The invention relates to a package system with an expander device for keeping an opening in a pouch open and to a method of using the package system. Technical background

Consumer products, such as food, cosmetics, cleaning supplies or medicine, are often filled and packaged in bags or pouches large enough to provide consumers with multiple servings. Commonly, the consumer opens the packaging along a tearing line or by cutting an opening in the packaging to access the contents of the packaging. If not all the product is used at once, the consumer is confronted with the problem of storing the remaining content for later use. Depending on the product, the consumer may choose to empty the product from the packaging into a storage box. Alternatively, the consumer may decide to leave the product inside the packaging and close the opened packaging with a clip, adhesive tape or rubber band that are often supplied with the packaging.

A known disadvantage of using a storage box in this manner is that there is a risk that substances or microorganisms left inside the storage box may contaminate or damage the product and thus, reduce product integrity and safety. This is particularly problematic for products that demand a high level of hygiene, product integrity and product safety, such as food products for infants or vulnerable persons.

While it is possible to circumvent the problem of initial product contamination by simply leaving the product inside the original packaging, it can be found that this solution is not only inefficient, difficult to use and unsuitable for performing accurate product dosing, but also that the initial level of hygiene inside the packaging cannot be maintained over an extended period of time. For example, depending on the size of the opening in the packaging, it can be difficult to retrieve the product inside the packaging with a dosing device, such as a scoop or cup. This problem may be aggravated each time the product filling level decreases. Thus, the dosing accuracy may be limited, inconsistent and/or deteriorate over time. Also, it is often relatively difficult to empty the packaging fully. Thereby, product utilisation is reduced and product is wasted. Further, before retrieving the product from the opened packaging, the user is often required to straighten up the packaging and to widen the opening by inserting fingers or the handle of a spoon to form a suitable access opening. However, this increases the risk of contaminating the product. Moreover, recycling of rubber bands, clips and adhesive tape can be challenging. Often, they are designed for single-use only so that it is difficult to reuse them. Accordingly, every packaging is commonly shipped including such closing means, which leads to a deterioration of the ecological footprint of each packaging. Thus, it becomes clear that known multi-serve packaging solutions are insufficient for storing and accessing products in a manner required for ensuring hygiene, safety and integrity of the product while keeping the ecological footprint of each packaging low.

Therefore, it is an object of the present invention to provide a device, a system and a method that allow to overcome known drawbacks of established packaging solutions, respectively. In particular, it is an object of the present invention to provide packaging solutions for safely storing the product inside its packaging after being opened while reducing the ecological impact of the packaging solution and ensuring usability, hygiene, product integrity and product safety, respectively.

Summary of the invention

These and other objects, which become apparent upon reading the description, are solved by the subject-matter of the independent claims. The dependent claims refer to preferred embodiments of the invention.

A first aspect of the present invention relates to an expander device for keeping a pouch opening of a pouch open. The expander device comprises a ring member, by which a central opening is at least partially surrounded. The ring member comprises an outer circumferential fitment section that at least partially surrounds the central opening and faces away from the central opening so as to be fitted against an inner side surface of a circumferential rim section of the pouch opening. The ring member is convertible between two constitutions, namely a collapsed constitution and an expanded constitution. In the collapsed constitution, the expander device can preferably be energized and/or be inserted into the pouch via the pouch opening with at least the fitment section. In the expanded constitution, the central opening can preferably be provided as an access opening to the pouch when the fitment section is (circumferentially) fitted against the rim section to keep the pouch opening (by exerting a compressive force) open. In its collapsed constitution, an outer circumferential perimeter of the ring member at the fitment section is smaller than in its expanded constitution. In other words: an expander device is provided that is suitable for keeping an opening (e.g. an aperture, orifice, perforation) in a pouch open. The expander device comprises a ring member with a central opening. For example, the ring member may comprise a (not necessarily circular, e.g. oval) body with an (e.g. oval) opening that may be arranged centrally thereon. The ring member may be a hollow cylinder (also called a cylindrical shell), for example. The central opening may extend along an axis that may be a rotation or symmetry axis of the hollow cylinder or ring member. The ring member comprises an outer circumferential fitment section that faces away from the central opening and that is suitable (or configured) for being fitted inside the pouch opening. Fitment of the fitment section against the inner side surface of the pouch opening may be achieved, for example, by the circumferential fitment section being engaged with or applying contact pressure to the inner side surface of the pouch opening. The circumferential fitment section may be at least a part (a section) of an external surface of the ring member, preferably of a mantle (shell) surface of the ring member. Preferably, the circumferential fitment section may extend at least partially along the circumference (i.e. complete outside edge) of the ring member. The ring member is preferably reversibly convertible (i.e. changeable, transformable) between two constitutions (configurations or states), namely a collapsed constitution (configuration/state) and an expanded constitution (configuration/state). In the collapsed constitution (configuration/state), the expander device may be configured for being inserted at least with the outer circumferential fitment section into the pouch via the pouch opening. In the expanded constitution (configuration/state), the expander device may be configured to provide the central opening as an access opening to the pouch when the outer circumferential fitment section is (circumferentially) fitted against the rim section to keep in this way the pouch opening (by compressive force) open. In its collapsed constitution (configuration/state), an outer circumferential perimeter (i.e. outside edge or circumference) of the ring member at the fitment section is smaller than in its expanded constitution (configuration/state). Preferably, the expander device may have a higher strain energy in the collapsed constitution (configuration/state) than in the expanded constitution (configuration/state). For example, the expander device maybe configured to change its shape under compressive load (e.g. so that the outer circumferential perimeter changes).

Thus, a device is provided, by which the pouch opening can be expanded so that, for example, the pouch opening (or pouch material defining the pouch opening) is straightened out, spread out, unfolded, and/or increased in its extension (e.g. diameter, width). This is facilitated by the expander device’s capability of being convertible between the following two constitutions: (i) A first constitution (the collapsed constitution) exists for inserting the expander device in the pouch opening. It is advantageous that the outer circumferential perimeter is reduced in this constitution so that the expander device can be adapted to access smaller pouch openings or openings that are crumpled or partially obstructed by flexible pouch material.

(ii) A second constitution (the expanded constitution) exists, where the expander device is securely held in place with respect to the pouch opening. By expanding the outer circumferential perimeter of the ring member in comparison to the collapsed constitution, the circumference and/or the outer circumferential fitment section expands (increases in size) so that through engagement (e.g. pressurizing) of the outer circumferential fitment section against the inner side surface of the pouch opening a holding force can be generated. Thus, the expander device can be secured by being fitted against the inner side surface.

Moreover, by providing the pouch with the central opening as a suitable access opening, it is possible to access the entire content of the packaging more easily. Once the packaging is emptied, the expander device can be cleaned and reused, thereby improving the environmental footprint of the individual packaging.

Thus, the expander device allows to overcome the drawbacks of known packaging solutions. According to a preferred embodiment, the ring member may be biased towards its expanded constitution when being converted from the expanded constitution into the collapsed constitution.

Thereby, the ring member can be designed to return automatically into a configuration of larger size (diameter) when the ring member is free from any external influences or forces. Thus, the ring member will be driven towards the expanded constitution as a state of equilibrium. Accordingly, excess energy (e.g. obtained through manual deformation) stored inside the ring member can be utilized for generating (compressive) holding forces that secure the ring member inside the pouch opening.

Alternatively or additionally, the ring member may be elastically deformed when being converted from the expanded constitution into the collapsed constitution. By configuring the conversion between the constitutions as elastic deformations, the ring member is reversibly convertible between the two constitutions. Thus, the ring member can be provided with the ability to resist a distorting influence and to return to its original shape when that influence is removed.

Preferably, the ring member may be elastically deformable single handedly and/or by applying (compressive) forces below tooN, more preferred below 50 N. Thereby, the ring member can be converted between the two constitutions by human strength. For example, the handgrip strength between thumb and middle finger may be used to define the maximum strength required to deform the ring member elastically.

According to a further preferred embodiment, the ring member may extend substantially within a plane. Preferably, the ring member may be configured such that its conversion between the collapsed constitution and the expanded constitution takes place within the plane.

Thereby, handling of the expander device is improved, as it is easier to hold the expander device in each constitution with one hand. Moreover, the planar extension of the ring member can be used for balancing and levelling dosing devices on the expander device as well as for receiving and storing dosing devices within the expander device. Also, manufacturing of the expander device is simplified. According to a preferred embodiment, the ring member may be circumferentially closed in at least the collapsed constitution. Preferably, the ring member may be circumferentially closed also in the expanded constitution. More preferred, the ring member maybe circumferentially closed independently from its respective constitution. Alternatively or additionally, the ring member maybe circumferentially closed (entirely) in the collapsed position and (partially) circumferentially open in the expanded position.

A closed profile of the ring member facilitates that pressure is exerted equally along fitment section onto the pouch opening. Thereby, the expander device can be secured more safely in the pouch opening. Also, mechanical characteristics, e.g. bending stiffness and rigidity, of the expander device can be improved. Further, handling as well as manufacturing can be simplified. According to a further preferred embodiment, the ring member may comprise circumferentially overlapping end sections. Alternatively, the ring member may comprise end sections that preferably may be formed as free ends (circumferentially) facing each other. Preferably, the end sections maybe configured to move (slide) relative to each other in a preferably guided manner.

Therein, the ring member may extend between the end sections. Preferably, the end sections may be free ends, respectively. The ring member maybe bendable. Preferably, the ring member may be configured such that the end sections may be moved relatively to each other under the influence of compressive force onto the fitment section. More preferred, the compressive force may be applied onto two sections of the fitment section that may be (provided) on opposite sides with respect to the end sections. Preferably, at least one of the end sections may be biased towards the respective other end section. More preferred, the end sections may be formed by a (stepwise) reduction in material. Preferably, the end sections may be configured such that the (combined) material thickness in an area of overlap between the end sections is similar or the same as for a section of the ring member extending between the end sections. It is also conceivable to provide one of the end sections with a circumferential insertion opening (such as a slit, e.g. in a wall portion of the ring member) that may correspond with the respective other end section to slide the end sections relatively to each other (in circumferential direction). For example, the expander device maybe configured as a clip collar.

Thereby, it is possible to change the size of the outer circumference of the ring member (expander device) by compressing and/ or expanding the ring member. In particular, the change in size (and/or constitution) can be achieved faster by providing both of the overlapping end sections relatively movable to each other. Thus, it is possible to change the constitution of the ring member by simply compressing two external points of the ring member. With other words: the size of the ring member can be changed by squeezing the ring member. Accordingly, the handling of the expander device is improved. Moreover, the level of hygiene can be increased as the expander device is only contacted by the operator on an outside (external) surface of the expander device that does not come into contact with the product inside the pouch.

According to a preferred embodiment, the expander device (or the ring member) may comprise gripping sections for receiving fingers of a user for gripping. Preferably, the gripping sections may be provided by dents in the expander device (or the ring member) that project towards the central opening. Preferably, the gripping section may be provided on opposite sides with respect to the overlapping end sections.

Thereby, handling of the expander device can be simplified and its ergonomics can be improved. Moreover, the hand span width required for gripping the expander device with one hand can be reduced, thus further improving handling of the expander device.

According to a further preferred embodiment, the fitment section may at least partially comprise an inhibiting feature. The inhibiting feature may be a structured surface that may comprise a rib and/or a dot structure. Alternatively or additionally, the inhibiting feature may be an outer inhibiting layer, such as a coating, a laminate or a sticker. Preferably, the inhibiting feature maybe made of an anti-skid material, such as rubber.

Thereby, it is possible to increase the friction between the (outward facing) surfaces of the ring member and the inner side surface of the pouch opening so that the expander device is held more firmly in the desired position. For example, the risk can be reduced that the expander device suddenly loosens from the pouch while travelling.

According to a further preferred embodiment, the expander device may comprise a(n upper) circumferential device rim section for supporting the expander device on the rim section of the pouch opening. The device rim section may protrude away from the central opening. Preferably, the device rim section may be provided adjacent to the fitment section and/or parallel to the plane. Preferably, the gripping sections maybe provided in the device rim section. Alternatively or additionally, the device rim section may be provided for supporting the expander device on a (support) rim section of a support for receiving the pouch with the expander device (in the expanded constitution). The support may be a storage container for receiving the pouch with the expander device (in the expanded constitution), the storage container having a container rim section as the support rim section. Alternatively, the support may be a support frame for receiving the pouch with the expander device (in the expanded constitution). The support frame having a frame rim section as the support rim section.

Thereby, it is possible to provide the expander device, for example, with a flange-like structure facing towards and/or away from the central opening. This facilitates, for example, exact positioning of the expander device on the pouch and/or the support, e.g. the storage container or the support frame. Moreover, hygiene and product integrity can be improved as product cannot fall between a support (e.g. a container wall of the storage container) and the pouch when being retrieved from the pouch.

According to a preferred embodiment, the expander device (or at least its ring member) may have a round, circular, oval, square, rectangular, elliptic, or polygonal shape. For example, when looking onto the central opening, the ring member (and/or the central opening) may have a round, circular, oval, square, rectangular , elliptic, or polygonal shape. The expander device (or at least or only the ring member) may be made of plastic material or bioplastics. For example, polypropylene (PP), polyethylene (PE), polyphenylene ether (PPE) or resin may be used. Preferably, a combination of PE and silicone, or a combination of plastic and metal, or a combination of plastic and paper may be used. Preferably, the expander device may be made of a bendable material or a material having a shape memory. Preferably, recyclable and/or biodegradable materials may be used. Alternatively or additionally, an antibacterial material or coating may be used. A synthetic or natural resin may be used, for instance.

Thereby, manufacturing the expander device can be simplified. Also, the expander device can be used in a multitude of different applications.

According to a further preferred embodiment, the expander device may further comprise a lid for closing the central opening at least in the expanded constitution. Preferably, the lid may be provided separately or it may be formed integrally with the expander device (or the ring member).

Thereby, it is possible to increase the functionality of the expander device as it is not only possible to keep the pouch opening open, but also to provide means for closing the pouch after completion of a dosing process, for example. Thus, a pouch being provided with such expander device can be stored advantageously and the product can be kept fresh and hygienic. Moreover, no extra storage box for placing the opened pouch inside may be needed. Thus, the ecological footprint of the packaging solution can be improved.

According to a preferred embodiment, the expander device may comprise (at least one or multiple) support elements for receiving a dosing device at or within the ring member. For example, the dosing device maybe a spoon or scoop. Thereby, a dosing device can be stored securely at or preferably even within the expander device. At least one of the support elements may protrude laterally inward from the ring member (into the central opening). Preferably, the support elements may be arranged opposite to each other (e.g. with respect to the central opening) and/ or facing each other. The support elements may project into the central opening. Preferably, the support elements may be arranged at one of the two opposite ends of the ring member. The support elements may be arranged equally distanced from each other along the perimeter (circumference) of the ring member. Preferably, the support elements may (at least) partially cover the central opening. Preferably, the support elements may have a (hollow) semicircle or arc shape. Preferably, the support elements may be integral with the ring member. However, it is also conceivable that the support elements may be removable or detachable. Preferably, the support elements may extend within the same plane as the ring member.

Alternatively or additionally, the support elements may comprise surface features for securing (attaching/holding) the dosing device to the ring member. For example, the surface features may be fasteners, protruding structures, clips, latches or spring locks, and/ or a surface for increasing friction or adhesive forces between the ring member and the dosing device. It is also conceivable that the handle and/or the bowl maybe provided with locking structures that may be configured to correspond with the surface features provided on the support elements.

A further aspect of the present invention relates to a package system. The package system comprises a pouch carrying a food product. The package system comprises also an expander device as described above. In the collapsed constitution of the ring member, the expander device with at least its fitment section is to be inserted into a pouch opening of the pouch to keep the pouch opening open by fitting the fitment section against an inner side surface of a circumferential rim section of the pouch opening when the ring member is converted into the expanded constitution. For example, the fitment section maybe engaged with the inner side surface and/or the fitment section may apply contact pressure onto the inner side surface in the expanded constitution.

Thereby, all effects described above for the expander device can also be achieved with the package system. Furthermore, it is possible to provide a package system with an expander device that is easy to clean and reusable so that packaging material can be reduced. In particular, the provision of separate elements for retrieving product from the pouch, such as a spout, can be avoided. Therein, it can be achieved that instead of having to provide each pouch with a separate opening means, the expander device only lO needs to be provided once for the consumer and can be reused subsequently. Thus, the package system can overcome the drawbacks of known packaging solutions.

According to a preferred embodiment, the package system may further comprise a support for supporting the pouch through the expander device fitted thereto in its expanded position. Preferably, the support may have a support opening for receiving the pouch and the expander device.

By providing a support, pouches that do not possess sufficient rigidity to stand upright on their own can be used more easily in the package system. Such configuration may also be advantageous once filling levels of the product become low. Also, the package system can be used for travelling or in applications subjected to movement.

Preferably, the device rim section, if present, is supported on a support rim section delimiting the support opening.

Thereby, a secure and stable support can be provided.

According to a preferred embodiment, the package system may comprise a storage container as the support. Preferably, the storage container may have a container opening as the support opening for receiving the pouch and the expander device.

By providing a storage container, pouches that do not possess sufficient rigidity to stand upright on their own can be used more easily in the package system. Such configuration may also be advantageous once filling levels of the product become low. Also, the package system can be used for travelling or in applications subjected to movement. Also, the storage container may completely house the pouch, which is thus securely protected inside the storage container.

According to a preferred embodiment, the package system may comprise a support frame as the support. The support frame may comprise a base, an upper ring defining the support opening (in the following also referred to as “frame opening”), and a frame structure connecting the base and the upper ring so as to surround a receiving space for receiving the pouch.

By providing a support frame, pouches that do not possess sufficient rigidity to stand upright on their own can be used more easily in the package system. Such configuration may also be advantageous once filling levels of the product become low. Using a frame structure also allows for a rigid but lightweight support. Moreover, the open frame structure allows for making the interior visible, so that the content of the support can be easily inspected without removing the pouch. For instance, this allows for information on the pouch be visible, like product information, nutrition facts, preparation instructions, etc.

The frame structure may comprise vertical bars, which are preferably evenly distributed over the circumference of the support.

Thereby, a stable construction with minimal material and high visibility of the interior can be obtained.

According to a further preferred embodiment, in the expanded constitution, the expander device (preferably at least its ring member) may press the rim section towards or against a circumferential inner wall section of the support, e.g. the storage container or the support frame, preferably of the or at its upper ring. Preferably, the expander device (preferably at least its ring member) may press the rim section against a circumferential inner wall section at or adjacent to the support opening, e.g. the container opening or the frame opening. Preferably, in the expanded constitution, the rim section may be squeezed or clamped between the ring member and the inner wall section.

Thereby, the pouch opening can be kept safely in place inside the storage container. Moreover, with this configuration, it can be ensured that the space inside the storage container is used and that no gaps exist between the storage container and the pouch at least near (adjoining) the container opening. Thus, hygiene can be improved.

According to a preferred embodiment, the package system may further comprise a dosing device such as the above-mentioned dosing device.

For example, the dosing device may be a spoon or scoop. The dosing device may comprise a handle and a bowl preferably having a defined volume with an opening. The handle maybe adjustable in length (e.g. comprising a telescopic slide-out mechanism or by attaching extension elements). Thereby, it is possible to provide a dosing device that is easy to operate and that is adjustable in size (length) to correspond with the size of the central opening, the size of the pouch opening and/or the depth of the pouch. The handle may comprise structures, such as ribs, for improving the bending stiffness and rigidity of the handle. Thereby, dosing (scooping) of substances can be facilitated that require a certain amount of force to be retrieved. For example, if powdery substances clump together it can be difficult to retrieve the substance without putting some strain on the dosing device.

Preferably, the dosing device (e.g. the handle and the bowl) may extend within a single plane. The handle may extend laterally away from the opening of the bowl. Preferably, the bowl may have a similar (or maximum) height to the height of ring member.

Thereby, the dosing accuracy can be improved as excess powder can be removed easily from the bowl. Also, it is possible to place the dosing device on a flat side, which simplifies storage and securing the dosing device. The dosing device may be made from any material, such as plastic (e.g. PE), metal, and/or a fiber-based material, such as paper, cardboard or pulp. Thereby, the ecological impact of providing a package system with a dosing device can be reduced as the dosing device maybe produced from sustainable, recyclable and/or compostable materials. Preferably, the dosing device may be configured to be arrangeable within the central opening such that the dosing device is (entirely enclosed) within the ring member. Preferably, the expander device may be arranged inside the pouch opening such that the dosing device maybe received by the support elements at a lower end of the ring member (preferably, the lower end being the end facing towards a substance contained inside the pouch when the expander device is inserted in the pouch opening).

A further aspect of the present invention relates to a method for use of a package system. Therein, a package system as described above is provided. The ring member is converted (e.g. compressed or squeezed) from the expanded constitution into the collapsed constitution. The expander device is inserted into the pouch opening with at least the fitment section. The ring member is converted (e.g. released) from the collapsed constitution into the expanded constitution so that the fitment section fits against the inner side surface of the rim section to keep the pouch opening open. For example, the fitment section may engage with the inner side surface or the fitment section may apply contact pressure to the inner side surface in the expanded constitution. Preferably, the pouch may be opened, for example with an opening device, to provide a pouch opening. The pouch may be closed with a lid suitable for closing the central opening. The lid maybe preferably attached to the expander device. Thereby, it is possible to derive all effects of the package system. The method allows for leaving the product inside its original packaging. Advantageously, its original packaging commonly already supplies the properties required for safely storing the product. Further, the method allows for a hygienic and safe use of the package system and improves the utilisation of product contained inside the pouch. Filling the product in a separate storage container is not required so that the risk of contaminating product with external substances or bacteria can be reduced. By providing a reusable and washable expander device, the environmental impact of using package systems can be improved.

According to a preferred embodiment, a support, preferably a storage container or a support frame, of the package system may be provided. The pouch may be received inside the support, e.g. the storage container or the support frame. Preferably, when converting the ring member from the collapsed constitution into the expanded constitution, the rim section may be pressed at least with the ring member towards or against a circumferential inner wall section of the support, e.g. the storage container of the support frame. Alternatively or additionally, the rim section may be preferably pressed at least with the ring member towards or against a circumferential inner wall section of the support, e.g. the storage container or the support frame, at or adjacent to the support opening (e.g. the container opening or the frame opening). Optionally, the expander device, once being connected to the pouch, may be attached to (e.g. hung into) the support (e.g. the storage container or the support frame), preferably at the support opening (e.g. the container opening or the frame opening). Preferably, the support (e.g. the storage container or the support frame) (and/or the support opening, e.g. the container opening or the frame opening) may be closed with a support lid (e.g. a container lid or a frame lid). Preferably, the dosing device maybe placed (and secured) inside the expander device.

Such specifications of the method allow to use pouches that are (significantly) smaller than the provided support (e.g. the storage container or the support frame) as the expander device is suitable for providing sufficient holding forces and guidance for using the pouch with the support (e.g. the storage container or support frame). In addition, the method can be applied to a multitude of different applications. - Brief description of drawings

The Figures show different views and aspects of embodiments of the invention.

A first aspect of the present invention relates to a package system 200. Figures 1, 2, 6 and 13 to 15 show exemplarily different embodiments and aspects of the package system

200.

The package system 200 comprises a pouch 400 for carrying a food product. An example for the pouch 400 is exemplarily illustrated in Figures 1, 2, 6 and 13 to 15. The pouch 400 may be suitable to carry food products and/or it may carry food products, for example. Preferably, the pouch 400 may carry granular or powdery food products, such as milk powder or coffee beans. However, it is also conceivable that the pouch 400 may carry different food products or non-food products, such as washing powder. The pouch 400 may be provided, for example, as stand-up packaging, sachet, or bag, such as a gusseted bag. Preferably, the pouch 400 may be made of a paper, cardboard, metallic, metallized and/ or plastic material. Preferably, the pouch 400 may be made of a material that comprises at least sufficient rigidity to stand upright on its own. Preferably, the pouch 400 may be made of a stretchable material. The pouch 400 may be circumferentially sealed by heat sealing and/or may comprise tearing lines for opening the pouch 400 along one of its edges to provide an opening therein. Preferably, the pouch 400 may comprise a volume between 200 ml and 10 litres. More preferred, the pouch 400 may comprise a volume between 200 ml and 3.5 litres. However, this is not a complete enumeration and other configurations of the pouch 400 are conceivable.

The pouch 400 may comprise an opening, such as the pouch opening 411, preferably on an upper end or an upper side portion of the pouch 400. Figures 2, 6, 14 and 15 show this exemplarily. For example, the pouch opening 411 may be provided by cutting an opening in the pouch 400 or by opening the pouch 400 along one of its edges, seams or sealing lines. Preferably, the pouch opening 411 may comprise a circumferential rim section 412. The circumferential rim section 412 may define the pouch opening 411. The pouch opening 411 maybe formed by an inner side surface 413. The inner side surface 413 may comprise the rim section 412. Figures 2, 6, 14 and 15 show this exemplarily. The pouch opening 411 may have any shape or form. For example, the pouch opening 411 may be round or rectangular.

The package system 200 further comprises an expander device too for keeping the pouch opening 411 of the pouch 400 open. Figures 1 to 15 show exemplarily different views and aspects of different embodiments of the expander device too. The expander device too may also form an independent part of the invention.

The expander device too may have a preferred operational orientation with respect to the pouch 400. Therein, for example, the expander device too may be preferably configured such that in operation, it is arrangeable on the pouch 400 such that one of the expander device’s too two opposite ends (sides) faces upwards (away) from the pouch opening 411 (thus, being an upper end of the expander device too) while the respective other end (side) faces towards the pouch opening 411 (thus, being a lower end of the expander device too). Figures 2, 6, 9, 11, 12, 14 and 15 show such an operational orientation exemplarily. However, the Figures are only examples and the expander device too may take other orientations in operation or may be used independently from its orientation.

Preferably, the expander device too may have a shape, layout or form that may correspond with the shape of the pouch opening 411. The size of the expander device too may correspond with and/ or may exceed the size of the pouch 400 or pouch opening 411. The expander device too maybe designed such that it can be handled by an operator with one or two hands. Figures 2 and 6 to 8 as well as Fig. 15 show this exemplarily. A maximum size (diameter or width) of the expander device 100 maybe delimited by the average hand span width of a human.

Preferably, the expander device 100 may be made of metal or plastic material, such as PP, PE, PPE or resin. Alternatively or additionally, combinations of these materials may be used. Preferably, sustainable, recyclable and/or biodegradable materials may be used. For example, the expander device 100 may be made from pulp or natural resin. More preferred, the expander device 100 may be made from a combination of such materials, such as a combination of PE and fibre (molded) based materials, or of PE and silicon, or of PE and a thermoplastic. However, these are only examples and not a complete enumeration.

The expander device too comprises a ring member 110, which surrounds at least partially a central opening 111. This is exemplarily illustrated in all Figures.

The ring member 110 (and/ or the expander device too) may have any shape or form. For example, the ring member 110 (and/or the expander device too) may have a round, circular or oval shape such as exemplarily illustrated in Figures 1 and 3 to 15. Alternatively, the ring member too (and/ or the expander device too) may have a square, rectangular, or polygonal shape such as exemplarily shown in Figure 2. The ring member 110 may be circumferentially closed. Preferably, the ring member 110 (and/or the expander device too) may extend substantially within a plane. This is shown in all Figures. Preferably, the ring member 110 (and/or the expander device too) may be a hollow volume or body, such as a hollow cylinder (e.g. Figures 1 and 3 to 15) or hollow block (e.g. Figure 2).

Preferably, the central opening 111 maybe centred with respect to the ring member 110. Further, the central opening 111 maybe surrounded completely by the ring member 110 as illustrated in all Figures. However, this is not to be considered delimiting. For example, the ring member 110 may be slotted. The central opening 111 may completely penetrate the ring member 110 and/or the expander device too. For example, the central opening 111 may form a passage between opposite ends (e.g. the upper end and the lower end) or sides of the expander device too. The central opening 111 may have any shape and form. The central opening 111 may have dimensions, such as width or diameter, that may be sufficient for accessing the inside of the pouch 400 with a dosing device, like a spoon or cup. For example, the central opening 111 may have a diameter within the range of 1 cm to 30 cm. The ring member no comprises an outer circumferential fitment section 112 for being fitted against the inner side surface 413 of the circumferential rim section 412 of the pouch opening 411. Therein, the outer circumferential fitment section 112 surrounds at least partially the central opening 111 and faces away from the central opening 111. For example, the circumferential fitment section 112 may be (at least a section of) a (external) mantle surface of the ring member no. All Figures show this exemplarily.

The outer fitment section 112 may taper with increased distance from one (the upper) side of the central opening 111 to the other (the lower) side of the central opening 111. While shown in all Figures, it appears that Figures 3, 4, 7, 8, 11, 12 and 13 are particularly suitable for exemplarily illustrating this configuration. Preferably, the operational orientation may be determined by the different diameters on the different sides. Preferably, the upper side of the central opening 111 may have a larger diameter than the lower side.

Preferably, the outer fitment section 112 may at least partially comprise an inhibiting feature (not illustrated). The inhibiting feature maybe a structured surface or an outer layer for inhibiting relative movement between the outer fitment section 112 and the inner side surface 413, for example. Therein, the inhibiting structure may be a rib structure or a dot structure. Alternatively or additionally, the inhibiting structure may be a coating, a laminate or a sticker. The inhibiting structure may be made of an anti skid material like rubber.

The ring member no is convertible between at least two constitutions, namely a collapsed constitution, where the expander device 100 is to be inserted with at least the fitment section 112 into the pouch 400 via the pouch opening 411, and an expanded constitution, where the central opening 111 provides an access opening to the pouch 400 by being fitted with the fitment section 112 (circumferentially) against the rim section 412 to keep the pouch opening 411 open. An outer circumferential perimeter of the ring member no at the fitment section 112 is smaller in its collapsed constitution than in its expanded constitution. Figures 6, 8 and 15 show the ring member no exemplarily in its (“a”) collapsed constitution. Figures 1 to 7, 9 to 12, 14 and 15 show the ring member no exemplarily in its (“a”) expanded constitution, respectively.

The expander device 100 is configured for being inserted into the pouch opening 411 in the collapsed constitution. Preferably, at least the fitment section 112 is to be inserted. This is done to allow for the expander device 100 to keep the pouch opening 411 open by fitment of the fitment section 112 against the inner side surface 413 of the pouch opening 411 when the ring member 110 is converted into the expanded constitution. This is exemplarily illustrated in all Figures but particularly illustrated in Figures 2, 6 and 15.

Preferably, the ring member 110 may be configured such that its conversion between the collapsed constitution and the expanded constitution takes place within a plane or within the same plane, in which the ring member 110 may substantially extend. The ring member 110 may be circumferentially closed at least in the collapsed constitution and preferably also in the expanded constitution. This is exemplarily illustrated in all Figures. Preferably, in the expanded constitution, the ring member 110 may have a lateral extension (e.g. diameter, length and/or width) in one extension direction (within the plane) of 3 cm to 90 cm, more preferred of 3 cm to 35 cm.

Generally, it is to be noted that while the Figures may show only individual examples for the respective constitutions of the ring member 110, it may be still possible to arrange the ring member 110 in different constitutions that may still fall within the specifics of a “collapsed constitution” or of an “expanded constitution” as defined above. Thus, if, for instance, the pouch material cannot be compressed or expanded by the ring member 110 in the manner illustrated in Figures 2, 6 and 15, the ring member 110 may take a constitution different from the illustrated constitution, which, however, can still be compliant with the definition of the expanded constitution.

For reducing the outer circumferential perimeter of the ring member 110 at the fitment section 112 in its collapsed constitution when compared to its expanded constitution, a circumference reduction mechanism may be provided on the expander device too. For example, the circumference reduction mechanism may comprise elements that may be compressible, shrinkable, relatively pivotable or linearly movable with respect to each other. However, these are only examples and other ways of reducing the circumference of the outer circumferential perimeter of the ring member 110 are conceivable.

For example, the ring member 110 may comprise circumferentially overlapping end sections 115, 116, 117, 118 (in the following referred to as “115-118”), which may be configured to move or slide relative to each other (preferably in a guided manner). This is exemplarily illustrated in all Figures. The ring member 110 (or the expander device 100) may preferably extend between the overlapping end sections 115-118. Alternatively, it is also conceivable that the ring member 110 may comprise end sections that overlap at least in the collapsed constitution (but may or may not overlap in the expanded constitution). The respective end sections may be separated from each other by a gap provided in the ring member no. The end sections may comprise a corresponding clip structure 130, respectively, to slidably connect the free ends and keep the ring member no in a pre-tensioned state in the expanded configuration, as exemplarily illustrated in

Figures 13 to 15. Therefore, one of the end sections may comprise a circumferential insertion opening (such as a slit, e.g. in a wall portion of the ring member) as a first part 131 of the clip structure 130, and the respective other end section may comprise a clipable tip (e.g. a snap lug) as a second part 132 of the clip structure 130 to be snapped into the insertion opening 131 for slidably securing these free end sections. From this pre-tensioned state, the ring member 110 can then be transferred into the collapsed constitution as described, i.e. by sliding the end sections relatively to each other (in circumferential direction). Thereby, the end section comprising the clipable tip 132 may slide and thus be guided within the insertion opening 131. For example, the expander device too may be configured as a clip collar. This example is illustrated in Figures 13 to

15·

Preferably, at least one of the end sections 115-118 may be (radially) biased (preloaded) towards the respective other end section 115-118. In the Figures, for example, first end section 115 may be biased against second end section 116 so that a rigid structure is formed by the two end sections 115, 116. Similar can be found for third end section 117 and fourth end section 118.

The ring member 110 (or the expander device 100) maybe configured such that the end sections 115-118 may be moved relatively to each other under the influence of a compressive force being applied onto two (different) sections of the fitment section 112 opposite to each other with respect to end sections 115-118. The ring member 110 may be elastically deformed (bent) when being converted from the expanded constitution into the collapsed constitution. This is exemplarily shown by Figures 7 and 8, where the ring member 110 may be bent slightly inwards in the collapsed constitution.

The two sections of the fitment section 112 for applying a compressive force may be provided as dedicated structures of the expander device 100. For example, the expander device 100 may comprise gripping sections 160 for receiving fingers 700 of a user for gripping the expander device 100. The gripping sections 160 may be provided by dents in the ring member 110 (or the expander device 100). The dents may project towards the central opening 111. The gripping sections 160 may be provided on opposite sides with respect to the overlapping end sections 115-118. This is exemplarily illustrated in Figures 1 to 8. Naturally, the examples illustrated in Figures 9 to 15 may also be provided with gripping sections 160. The gripping sections 160 may be provided along the circumference of the ring member 110. Preferably, the gripping sections 160 may be provided equally spaced from the end sections 115-116 and/ or may be provided such that a connecting line of two gripping sections 160 intersects with the centre of the ring member 110. However, these are only examples and the gripping sections 160 may be arranged freely on the ring member 110.

Preferably, the ring member 110 may be biased towards its expanded constitution when being converted from the expanded constitution into the collapsed constitution. This may be achieved, for example, by providing the ring member 110 from a material, which may have a shape memory. Alternatively or additionally, the ring member 110 may be a (bendable) spring.

The end sections 115-118 may be free ends 115-118 of the ring member 110, for example. Alternatively or additionally, the end section 115-118 may be formed as guiding fingers 114 and corresponding guiding tracks 119. This is exemplarily illustrated in Figures 3 to 5 and 7 to 12.

The guiding fingers 114 may be formed as recesses from the fitment section 112. The guiding tracks 119 may be formed as recesses from an inner surface 113 of the ring member 110 delimiting the central opening 111. Preferably, the guiding tracks 119 and the guiding fingers 114 are configured such that the ring member 110 has a constant ring thickness at the overlapping end sections 115-118. This is exemplarily illustrated in Figures 3 to 5 and 7 to 12. This configuration can be advantageous since, in the connected state of the expander device 100 and the pouch 400, there is uniformity along the edges of the pouch opening 411 as the ring member 110 has a uniform thickness along its circumference. Accordingly, the fitment section 112 pushes uniformly against the pouch material so that steps or bulges on the outside of the rim section 412 can be avoided. Thereby, the aesthetics of the packaging system 200 can be improved. Moreover, the risk of the pouch 400 being torn, cut or burst on sharp edges of such steps or bulges can be reduced.

Preferably, the guiding fingers 114 may be guided on the inside of the ring member 110 along the guiding tracks 119. Therein, preferably, the guiding tracks 119 maybe provided on the inner surface 113 of the ring member 110. Preferably, the guiding fingers 114 may contact the guiding tracks 119 to overlap with a surface facing away from the central opening 111. Thereby, it can be avoided that the ring member 110 becomes tangled inside the pouch 400 when being inserted into the pouch opening 411.

Preferably, the guiding fingers 114 and/ or the guiding tracks 119 may be arranged one below the other as exemplarily illustrated in Figures 3 to 5 and 7 to 8. Depending on the orientation of the guiding fingers 114 with respect to their free ends 116, 117, the free ends 115, 118 of the guiding tracks 119 may be provided on the same side or on opposite sides with respect to the center of the central opening 111. In the expanded constitution, the guiding fingers 114 may overlap with the guiding tracks 119 at least with their respective free ends 115-118.

The expander device 100 maybe manufactured by injection molding.

The expander device 100 may comprise a lid for closing the central opening 111 at least in the expanded constitution (not illustrated). The lid maybe provided separately or it may be integrally formed with the expander device 100 or the ring member 110. For example, the lid may be connected to the expander device 100 via a hinge.

Preferably, the package system 200 may further comprise a support 500 with a support opening 511, which may be suitable for receiving the pouch 400 and the expander device 100.

Preferably, the support 500 maybe a storage container with a container opening as the support opening 511, which may be suitable for receiving the pouch 400 and the expander device 100. The storage container 500 is exemplarily illustrated in Figures 1, 2 and 6.

Alternatively, the support 500 may be a support frame. This is exemplarily illustrated in Figures 13 to 15. The support frame 500 comprises a base 501 for a stable stand of the support 500. Moreover, the support frame 500 comprises an upper ring 502 defining the support opening 511; i.e. the frame opening 511. The support frame 500 further comprises a frame structure 503 connecting the base 501 and the upper ring 502 so as to surround a receiving space 505 for receiving the pouch 400. The frame structure 503 may comprise vertical bars 504. In the illustrated embodiment of Fig. 13, the vertical bars 504 are evenly distributed over the circumference of the support 500. While the support frame 500 as shown comprises three vertical bars 504, the invention is not limited to a number or layout of the frame structure 503.

The support (e.g. the storage container or support frame) 500 may have any shape or form. The support (e.g. the storage container or support frame) 500 may be suitable for receiving the pouch 400 and the expander device 100. Preferably, the support (e.g. the storage container or the support frame) 500 may have a volume between 200 ml and 10I. The support (e.g. the storage container or the support frame) 500 maybe made of a glass, metal, plastic and/or paper material. Preferably, the support (e.g. the storage container or the support frame) 500 may have an opening, such as the support opening

(e.g. the container opening or the frame opening) 511, on one (an upper) end. The support opening 511 may comprise a support rim section 513. In case of a storage container as support 500, the container opening 511 may comprise or be defined by a container rim section 513. In case of a support frame as the support 500, the support opening 511 may comprise or be defined by the frame rim section 513 (e.g. of the upper ring 502) Preferably, the support opening (e.g. the container opening or the frame opening) 511 may be defined (on the inside) by the support rim section (e.g. the container rim section or frame rim section) 513. In case of a storage container as the support 500, a circumferential inner wall of the storage container 500 may define the inside of the storage container 500. A circumferential inner wall section 512 may be adjacent to the container opening 511. This is exemplarily illustrated in Figures 1 and 6.

The expander device 100 may be configured to sit on or be fitted onto the support (e.g. the storage container or support frame) 500. Preferably, the shape of the expander device 100 may correspond with the shape of the support opening (e.g. the container opening or the frame opening) 511. For example, the expander device 100 maybe fitted with the ring member 110 into the support opening (e.g. the container opening or the frame opening) 511. This is exemplarily illustrated in Figures 2, 6, 14 and 15. For supporting the expander device 100 on the support rim section (e.g. the container rim section or the frame rim section) 513, the expander device 100 may comprise a circumferential device rim section 180 protruding away from the central opening 111. The device rim section 180 may extend parallel to the plane (including extending within that plane), in which the ring member 110 may substantially extend. This is exemplarily shown in Figures 1 to 8 and 13 to 15 but Figures 1 and 3 to 5 and 13 appear to be particularly suitable for exemplarily illustrating this configuration. Naturally, the example illustrated in Figures 9 to 12 may also comprise the device rim section 180. The device rim section 180 may be and/ or function, for example, as a collar or flange, by which relative movement of the expander device 100 with respect to the support (e.g. the storage container or support frame) 500 and/ or the pouch 400 may be restricted in at least one, preferably at least two directions. It is also conceivable that the expander device 100 comprises the circumferential device rim section 180 for providing additional support for the expander device 100 on the rim section 412 of the pouch opening 411.

Further, in the expanded constitution, the expander device 100 (the ring member 110) may be configured to press the rim section 412 of the pouch opening 411 towards or against the circumferential inner wall section 512, which may preferably at or adjacent to the support opening (e.g. the container opening or the frame opening) 511. For example, the inner wall section 512 may be at a distance of up to 5 cm from the support opening (e.g. the container opening or the frame opening) 511, more preferred within 0,2 cm to 5 cm from the support opening (e.g. the container opening or the frame opening) 511. This is exemplarily shown in Figures 2 and 6. Alternatively or additionally, in the expanded constitution, the rim section 412 of the pouch 400 may be squeezed or clamped between the ring member 110 and the device rim section 180 of the expander device 100.

Preferably, the expander device too may comprise at least one support element 131, 132 for receiving a dosing device (such as the below described dosing device 300) within (and/or inside) the ring member 110. Preferably, two or more support elements 131, 132 may be provided. The support elements 131, 132 may have any configuration (shape, size, and/or their respective arrangement within the ring member 110) that is suitable for blocking a dosing device from falling through the central opening 111. The support elements 131, 132 maybe configured such that a dosing device is storable inside the ring member 110. For example, the support element 131, 132 may be a platform or a ledge protruding laterally inward from the inner surface 113 of the ring member 110. This is exemplarily illustrated in Figures 9 to 12 and 14. By providing the support elements 131, 132 in this manner, a dosing device can be stored securely within the expander device too. Thereby, the risk of contaminating the interior of the pouch 400 can be reduced since the operator can place a dosing device immediately after its usage inside the expander device too and thus, any contact with external surfaces or substances can be avoided.

At least one of the support elements 131, 132 may protrude laterally inward from the ring member 110 (into the central opening 111). Thereby, the support elements 131, 132 may (at least) partially cover the central opening 111. Preferably, the support elements 131, 132 may be arranged opposite to each other with respect to (the center of) the central opening 111. Preferably, the support elements 131, 132 may be arranged at one of the two opposite ends between which the ring member 110 extends (longitudinally). The support element 131, 132 may at least partially extend between the two opposite ends of the ring member 110. The support elements 131, 132 may be provided integral with the ring member 110. Preferably, the support elements 131, 132 may extend within the same plane (mentioned above) as the ring member 110. This is exemplarily shown in Figures 9 to 12. However, the support elements 131, 132 can be arranged also at any other position between the two opposite ends of the ring member 110. For example, the support elements 131, 132 may be arranged halfway between the two opposite ends of the ring member 110. The support elements 131, 132 may have the same shape and size, or they may be configured to be different to each other. For example, the support elements 131, 132 may have a (hollow) semicircle, arc or bow shape. This is exemplarily shown in Figures 9 to 12. Therein, a first support element 131 is exemplarily shown with a semicircle shape. In this illustrated example, a second support element 132 has the shape of a segment of a semicircle. However, these are only examples and other shapes are conceivable.

Further, the support elements 131, 132 may comprise surface features for securing (attaching/holding) a dosing device to (inside) the ring member 110. For example, the surface features may be fasteners, protruding structures, clips, latches or spring locks, and/or a surface layer for increasing friction and/or adhesive forces between the ring member 110 and a dosing device. Thereby, it can be achieved that a dosing device is not only kept from falling through the central opening 111 but also secured (fixed) in a defined position within the expander device too.

The package system 200 may further comprise a dosing device 300 for measuring and dispensing a suitable amount of product contained inside the pouch 400. For example, the dosing device 300 maybe a scoop, spoon or measuring cup. Figures 1, 2, 6, and 11 to 15 show the dosing device 300 exemplarily.

The dosing device 300 may comprise a handle 310 for being gripped and a bowl 320 for retrieving a defined amount of product from the pouch 400. Figures 11 and 12 illustrate certain aspects of the dosing device 300 exemplarily. Preferably, the bowl 320 may have a defined volume that may be open towards one side in a filling direction. The bowl 320 may comprise a defined surface structure. For example, slits penetrating a portion of the bowl 320 or ribs protruding therefrom may be provided as such surface structure. For example, the ribs may be used to indicate a certain filling level. Preferably, the bowl 320 may have a similar height as the ring member 110 so that the dosing device 300 can fit inside (within) the expander device 100. Thereby, the dosing device 300 can be stored inside the expander device 100.

The handle 310 may extend along a longitudinal direction. Preferably, the filling direction of the bowl 320 may be perpendicular to the longitudinal direction of the handle 310. Preferably, the handle 310 may comprise structures, such as ribs, for improving the bending stiffness and/or rigidity of the dosing device 300 in order to reduce the risk of the dosing device 300 breaking during scooping. The handle 310 may be adjustable in length. For example, the handle 310 may comprise a telescopic mechanism. Preferably, the handle 310 may be extendable in size through a spring mechanism (biased towards maximum length) or by attaching extension elements. Such configurations may be advantageous if the package system 200 is used with pouches 400 of different sizes. Preferably, the handle 310 may be attached to the bowl 320. The handle 310 may be integral with the bowl 320. The handle 310 may extend laterally away from the bowl 320 with respect to its opening. Preferably, the dosing device 300 (preferably the handle 310 and the bowl 320) may extend within a single plane.

The dosing device 300 may be made from any (food safe) material, such as plastic (e.g. PE), metal, and/or a fiber-based material, such as cardboard or pulp. The dosing device 300 may extend longitudinally with a length that corresponds with the diameter of the central opening 111. Preferably, the dosing device 300 may have a length that is smaller than the central opening 111 (at the lower end, for example).

It is also conceivable that, for example, the handle 310 and/or the bowl 320 may be provided with locking structures that may be configured to correspond with the surface features provided on the support elements 131, 132. The dosing device 300 may have a length that is larger than the distance (gap) between the two opposite support elements 131, 132. This is exemplarily illustrated in Figures 11 and 12.

Preferably, the expander device too may be arranged inside the pouch opening 411 such that - in the connected state of the pouch 400 and the expander device too - the support elements 131, 132 are at the lower end of the expander device too. Figures 9, 11 and 12 illustrate this orientation of the expander device 100 exemplarily. Thereby, it can be achieved that the dosing device 300 can be stored within the expander device 100 while not contacting any part of the substance contained inside the pouch 400. Accordingly, the risk of a user touching the substance when retrieving the dosing device 300 from the pouch 400 can be reduced.

Preferably, the dosing device 300 and the expander device 100 may be configured such that the dosing device 300 may be placeable onto the support elements 131, 132 such that the opening of the volume of the bowl 320 faces towards the lower end of the expander device 100 (and thus, towards the substance contained inside the pouch 400). Thereby, substances from a previous dosing process can fall back into the pouch 400 so that an accumulation and waste of substance can be reduced. The dosing device 300 may be placed and/or stored inside the expander device 100 in the collapsed constitution and/or in the expanded constitution.

The package system 200 may also comprise a support lid (e.g. a container lid or a frame lid) 550 for closing the support (e.g. the storage container or the support frame) 500, or at least the supporting opening (e.g. the container opening or the frame opening) 511. The support lid (e.g. the container lid or the frame lid) 550 may be a snap on lid, for example. Preferably, the support lid (e.g. the container lid or the frame lid) 550 may be a twist-off lid. This is exemplarily illustrated in Figures 1, 2 and 6. Alternatively or additionally, the support lid (e.g. the container lid or the frame lid) 550 may be connected to the support (e.g. the storage container or support frame) 500 via a hinge 551, as exemplarily illustrated in Fig. 14.

The lid 550 may comprise the support elements 131, 132, preferably at an inner surface facing towards the pouch 400 when closing the support 500 or its support opening 511. The dosing device 300 can thus be securely stored inside the package system 200.

Moreover, the package system 200 may also comprise an opening device 600 for opening the pouch 400. For example, the opening device 600 maybe scissors. Figures 1, 2, 6 and 15 show this exemplarily.

A further aspect of the present invention relates to a method for use of the package system 200. Figures 2, 6 and 15 show exemplarily various steps of different embodiments of a method for use of the package system 200. The method comprises the step of providing the package system 200 as described above. Preferably, the package system 200 may be provided with the a support (e.g. the storage container or the support frame) 500. The pouch 400 may be placed inside the support (e.g. the storage container or support frame) 500. Alternatively or additionally, the support (e.g. the storage container or the support frame) 500 may receive the pouch 400 inside. Preferably, the pouch 400 maybe opened to provide the pouch with an opening, such as the pouch opening 411. For example, the pouch opening 411 may be provided by manually tearing a tearing line of the pouch 400 with hand 700 or by using the opening device 600. This is exemplarily illustrated in Figures 2, 6 and 15.

The package system 200 is provided such that the ring member 110 is already in the collapsed constitution. Alternatively, the expander device 100 is provided in the expanded constitution and the ring member 110 is converted into the collapsed constitution. For example, the hand 700 maybe used to squeeze the ring member 110 in application directions AD, which are exemplarily indicated by arrows in Figure 6.

The expander device 100 is inserted with at least the fitment section 112 into the pouch opening 411. The ring member 110 is converted from the collapsed constitution to the expanded constitution so that the fitment section 112 fits against the inner side surface 413 of the rim section 412 to keep the pouch opening 411 open.

For example, the compressive force applied via the gripping sections 160 in the application directions AD may be released so that the ring member 110 strives to return to its original shape in the expanded constitution. Thereby, the ring member 110 may engage with the inner side surface 413 as it may obstruct a full recovery of the ring member 110 into the ring member’s 110 shape at equilibrium. Accordingly, the fitment section 112 may apply contact pressure onto the inner side surface 413 of the pouch 400. This is exemplarily illustrated in Figures 2, 6 and 15.

Optionally, when converting the ring member 110 from the collapsed constitution into the expanded constitution, the rim section 412 of the pouch 400 may be pressed (also) at least with the ring member 110 towards or against the circumferential inner wall section 512 of the support (e.g. the storage container or the support frame) 500 (preferably at or adjacent to the support opening 511, e.g. the container opening or the frame opening). This is exemplarily illustrated in Figures 2 and 6. Thereby, for example, the pouch opening 411 may be converted from a folded configuration that is less accessible to an unfolded configuration that allows easy access to the product inside the pouch 400. This is exemplarily indicated in Figures 6 and 15, where at first gussets block the available space in the pouch opening 411, and subsequently the expander device too provides the central opening 111 as an access opening to the pouch 400.

The support (e.g. the storage container or the support frame) 500 or at least its support opening (e.g. the container opening or the frame opening) 511 may be closed with the lid 550. It is also conceivable that the expander device too being already connected to the pouch 400 may be attached to (e.g. hung into) the support (e.g. the storage container or the support frame) 500 preferably at the support opening (e.g. the container opening or the frame opening) 511; this preferably such that the device rim section 180 is supported on the support rim section 513, as exemplarily illustrated in Fig. 14. The pouch opening 411 may then be closed by the lid 550 and/or the lid, which may be attached to the expander device too.

Preferably, the dosing device 300 maybe placed and stored on the support elements 131, 132 inside the expander device too, preferably in the expanded constitution, or at the lid 550. The dosing device 300 may be placed into the expander device too with the opening of the bowl 320 facing towards the inside of the pouch 400. Preferably, the dosing device 300 may be fastened to the support elements 131, 132 inside the ring member 110 or at the lid 550 by interlocking structures provided on the support elements 131, 132 and the dosing device 300.

The invention is not limited by the embodiments as described hereinabove, as long as being covered by the appended claims. All the features of the embodiments described hereinabove can be combined in any possible way and be provided interchangeably. In particular, as mentioned above, it is also conceivable that the above described expander device too may form an independent part of this invention.
