WALL OF A DISPENSER FOR WEB-SHAPED ABSORBENT MATERIAL

TECHNICAL FIELD

The disclosure relates to an outlet assembly for arrangement at a wall opening in an outer wall of a dispenser for web-shaped absorbent material. The disclosure further relates to a dispenser comprising an outlet assembly, and to a method for arranging an outlet assembly to an outer wall of a dispenser.

BACKGROUND

Dispensers for dispensing web-shaped tissue material for wiping or cleaning purposes are widely used. Web-shaped tissue material such as paper tissue material or nonwoven material come in a variety of shapes and sizes. Typically, the web-shaped tissue material may be provided in the form of a folded stack or in the form of a roll.

For example, for some applications, it is desired to provide the web-shaped tissue material in the form of a centrefeed roll, i.e. a roll where it is intended to feed the web material from the centre of the roll, by pulling the web material in a direction at least partly parallel to the roll centre axis.

The web shaped absorbent material may for example be perforated web-shaped absorbent material, where perforation lines may be arranged transverse the length of the web to divide the web shaped material into individual products.

Dispensers for dispensing perforated web-shaped absorbent materials may be provided with a dispensing element, such as a nozzle,

However, since it may sometimes be desired to provide for one-by-one product dispensing, whereas it is sometimes instead desired to provide for continuous dispensing of the web-shaped absorbent material, i.e., free flow dispensing, different dispensers having different dispensing outlets with e.g., different nozzles may be provided to meet the various needs. However, for reasons of efficiency and versatility, there is a desire to use the same basic dispenser with different dispensing outlets. As such, the dispenser may, for example, be used either for one-by-one dispensing or for free flow dispensing, depending on the dispensing outlet used.

However, to enable easy mounting and replacement of a dispensing outlet of a dispenser, it is required that the dispensing outlet may be arranged to the dispenser in a time efficient manner, while ensuring that the dispensing outlet is properly positioned at and arranged to the dispenser, such that the dispensing function is ensured.

In view of the above, there is a strive to develop improved technology relating to dispenser outlets, such as a need for an improvement or an alternative when it comes to providing a dispenser with the option of using different dispensing outlets with the same basic dispenser.

SUMMARY

An object of the disclosure is to provide a solution which fulfils one or more of the above- mentioned needs, and/or which at least provides a suitable alternative.

According to a first aspect of the disclosure, an outlet assembly according to claim 1 is provided.

Thus, an outlet assembly for arrangement at a wall opening in an outer wall of a dispenser for web-shaped absorbent material is provided. The outlet assembly is adapted to form an outlet for dispensing of the web-shaped absorbent material from the dispenser through the wall opening. The outlet assembly comprises:

- a first part defining a first outlet portion having an extension along a centre axis of the first part; and

- a second part defining a second outlet portion having an extension along a centre axis of the second part; wherein the first part comprises a first protruding portion extending in a direction along the centre axis of the first part and being configured to receive and hold a fastening member, and wherein the second part comprises a first fastening bore extending in a direction along the centre axis of the second part, the first fastening bore being configured to receive the fastening member, wherein the first part and the second part are configured to be attached to each other by providing the first part such that the first protruding portion faces the second part and by providing the second part such that the first fastening bore is aligned with the first protruding portion to allow insertion of the fastening member from the second part to the first part, and such that, when the first part and the second part are attached to each other, the first outlet portion and the second outlet portion form the outlet for dispensing of the webshaped absorbent material from the dispenser through the wall opening in a direction along an outlet axis.

By the provision of an outlet assembly as disclosed herein, an improved outlet assembly is provided which may facilitate attachment and detachment of the outlet assembly to and from a dispenser. This is achieved by the configuration of the first and second parts, which allows the fastening member to be inserted from the second part to the first part, implying, e.g., a robust and reliable attachment, and/or a fast and simple attachment/detachment procedure for a user. For example, by interconnecting the first and second parts of the outlet assembly as disclosed herein, the outlet assembly may be reliably attached to a dispenser without separately attaching the first part and/or the second part to the dispenser. Accordingly, by way of example, the outlet assembly may be reliably attached to a dispenser by providing an attachment between the first and second parts of the outlet assembly.

Optionally, the first part comprises a first protruding support portion extending in a direction along the centre axis of the first part and which is configured to be received in a wall bore of the outer wall when the first part and the second part are attached to each other, wherein the first protruding support portion is located radially outside the first outlet portion and at least partly radially inside the first protruding portion. A technical benefit may include that positioning and/or fixation of the first part to the second part and/or to the dispenser may be facilitated. For example, the first protruding support portion may allow a user to more easily position the first part with respect to the second part and/or to the dispenser. This may imply a faster attachment procedure, and/or a more reliable attachment, mitigating a risk of wrongly positioning the first part to the second part and/or to the dispenser. Further, the location of the first protruding support portion on the first part implies a compact configuration. Extending in a direction along an axis, such as along the centre axis of the first part, as used herein, may mean to extend in a direction parallel with the axis, or a direction substantially parallel with the axis, such as within a range of +- 5 degrees with respect to the axis.

Optionally, the first protruding support portion comprises a radially inner support portion extending in the direction along the centre axis of the first part, and the second part comprises a first recess extending in a direction along the centre axis of the second part and being located radially outside of the second outlet portion, and the radially inner support portion of the first protruding support portion is configured to be received in the first recess when the first part and the second part are attached to each other. A technical benefit may include that positioning and/or fixation of the first part to the second part and/or to the dispenser may be facilitated. For example, the first protruding support portion and the first recess may rotationally position the second part with respect to the first part and/or to the dispenser. Accordingly, this may imply a faster attachment procedure, and/or a more reliable attachment, mitigating a risk of wrongly positioning the first part to the second part and/or to the dispenser. By way of example, the mechanically cooperating features may facilitate positioning and/or fixation in that the person assembling the first and second parts may easily do so without having to visually check that the parts are correctly aligned. When attaching the first and second parts to each other, the mechanical connection between the first protruding support portion and the first recess may signal that the parts are correctly positioned in relation to each other.

Optionally, the first protruding support portion forms an X-shape, when viewed in a geometric sectional plane being perpendicular to the centre axis of the first part. A technical benefit may include that the first protruding support portion can be more easily manufactured, while still providing its intended function, e.g., to facilitate positioning and/or fixation of the first part.

Optionally, the first protruding support portion, such as the X-shaped first protruding support portion, comprises a first wall member extending radially and a second wall member extending in a tangential direction with respect to the centre axis of the first part, preferably wherein the radial extension of the first wall member and the tangential extension of the second wall member together form the X-shape. A technical benefit may include that the first protruding support portion can be more easily manufactured, while still providing its intended function, e.g., to facilitate positioning and/or fixation of the first part.

Optionally, the first protruding portion and the first protruding support portion are angularly offset by an angle, as seen in a circumferential direction of the centre axis of the first part, such that a first radially extending axis which extends from the centre axis of the first part and midway through the first protruding portion is angularly offset in the circumferential direction from a second radially extending axis which extends from the centre axis of the first part and midway through the first protruding support portion. A technical benefit may include that a more compact first part and/or outlet assembly can be achieved. For example, by the angular offset, a larger radial space for the first protruding portion and the first protruding support portion may be allowed without a need to expand the first part in the radial direction. Another technical benefit may include that the configuration of the dispenser may be facilitated, by more easily finding available space for receiving sections (e.g., the herein disclosed auxiliary opening and wall bore) for the first protruding portion and the first protruding support portion.

Optionally, the first part comprises at least two first protruding support portions, preferably three first protruding support portions, arranged spaced apart from each other in a circumferential direction of the first outlet portion. A technical benefit may include that positioning and/or fixation of the first part to the second part and/or to the dispenser may be further facilitated, e.g., allowing a user to find the right position of the first part more easily with respect to the second part and/or to the dispenser. This may also imply a further reliable attachment to the second part and/or to the dispenser.

Optionally, the at least two first protruding support portions, preferably the three first protruding support portions, are arranged equiangularly from each other in the circumferential direction of the first outlet portion. A technical benefit may include a facilitated positioning of the first part for a user during an attachment procedure, e.g., allowing the first part to be provided in more than one position with respect to the second part and/or to the dispenser.

Optionally, the first protruding portion comprises a first tower portion and a second tower portion extending in a direction along the centre axis of the first part, which first and second tower portions are separate with respect to each other such that they form a gap therebetween configured to receive and hold the fastening member. A technical benefit may include that a compact first protruding portion may be provided. This may for example provide more space for the outlet for dispensing of the web-shaped absorbent material.

Optionally, the first protruding portion has a maximum first length in a radial direction and a maximum second length in a tangential direction, as seen in a geometric sectional plane being perpendicular to the centre axis of the first part, wherein the second length is greater than the first length, such as at least two times greater than the first length. A technical benefit may include that a radially compact first protruding portion may be provided.

Optionally, the second part comprises a second recess extending in a direction along the centre axis of the second part and being aligned with the first fastening bore, wherein the second recess is configured to receive a top portion of the first protruding portion when the first part and the second part are attached to each other. A technical benefit may include that positioning and/or fixation of the first part to the second part and/or to the dispenser may be further facilitated, e.g., allowing a user to find the right position of the first part more easily with respect to the second part and/or to the dispenser. This may also imply a further reliable attachment to the second part and/or to the dispenser. By way of example, a more reliable attachment may be achieved in that the second recess may prevent the first protruding portion from expanding too much in the circumferential direction when the fastening member is inserted into the first protruding portion. Thereby, a more reliable attachment of the fastening member in the first protruding portion may be achieved, mitigating the risk of the fastening member being released from the first protruding portion.

Optionally, the second part comprises an outwardly facing peripheral surface which encloses the second outlet portion in a circumferential direction thereof, and the first fastening bore is located such that the fastening member, when being inserted into the first fastening bore, is at least partly located outside the outwardly facing peripheral surface. A technical benefit may include that the fastening member may thereby not interfere with the second outlet portion. This may imply a more reliable dispensing of webshaped absorbent material through the outlet assembly. For example, it has been realized that a uniform and smooth shape of the second outlet portion contributes to achieving a reliable dispensing of the web-shaped absorbent material. By the aforementioned location of the fastening bore, the shape of the second outlet portion may not be altered, e.g. a uniform and smooth shape can be provided.

Optionally, the outwardly facing peripheral surface comprises a third recess extending in a direction along the centre axis of the second part and being aligned with the first fastening bore, allowing the fastening member to be inserted into the first fastening bore. A technical benefit may include a more compact configuration, still allowing the fastening member to be easily inserted into the first fastening bore. A compact configuration may be advantageous in that it may give more room for other parts of the dispenser, and/or enable for a larger free space close to the dispenser, thereby allowing e.g. fingers of a person to grab the outlet assembly during mounting and dismounting.

Optionally, the second part comprises at least two first fastening bores, preferably three first fastening bores, arranged spaced apart from each other in a circumferential direction of the second outlet portion. A technical benefit may include a more stable and robust attachment between the first and second parts. This may also imply a more reliable dispensing of web-shaped absorbent material through the outlet assembly, e.g., a risk of departing from the intended shape of the outlet due to an incorrect attachment can be mitigated.

Optionally, the at least two first fastening bores, preferably the three first fastening bores, are arranged equiangularly from each other in the circumferential direction of the second outlet portion. A technical benefit may include a facilitated positioning of the second part for a user during an attachment procedure, e.g., allowing the second part to be provided in more than one position with respect to the first part and/or to the dispenser.

Optionally, the first part comprises at least two first protruding portions, preferably three first protruding portions, arranged spaced apart from each other in a circumferential direction of the first outlet portion. A technical benefit may include a more robust attachment between the first and second parts. This may also imply a more reliable dispensing of web-shaped absorbent material through the outlet assembly, e.g., a risk of departing from the intended shape of the outlet due to an incorrect attachment or movement between the first and second parts can be mitigated. A technical benefit may include a facilitated positioning of the first part for a user during an attachment procedure, e.g., allowing the second part to be provided in more than one position with respect to the first part and/or to the dispenser.

Optionally, the at least two first protruding portions, preferably the three first protruding portions, are arranged equiangularly from each other in the circumferential direction of the first outlet portion. A technical benefit may include a facilitated positioning of the first part for a user during an attachment procedure, e.g., allowing the first part to be provided in more than one position with respect to the second part and/or to the dispenser.

According to a second aspect of the disclosure, a dispenser according to claim 18 is provided.

Thus, there is provided a dispenser for web-shaped absorbent material comprising an outer wall defining a wall opening extending along an outlet axis through the outer wall, the dispenser further comprising an outlet assembly according to any one of the embodiments of the first aspect of the disclosure. When mounted at the wall opening of the dispenser, with the first and second parts of the outlet assembly attached to each other, a portion of the outer wall surrounding the wall opening of the dispenser is positioned between the first and second parts of the outlet assembly and is firmly held between the first and second parts of the outlet assembly.

Advantages and effects of the second aspect of the disclosure are largely analogous to the advantages and effects of the first aspect of the disclosure, and vice versa. It shall also be noted that all embodiments of the first aspect of the disclosure are applicable to and combinable with all embodiments of the second aspect of the disclosure, and vice versa.

Optionally, the outer wall further defines an auxiliary opening having an extension in a direction along the outlet axis through the outer wall and being located radially outside the wall opening, wherein the dispenser is configured such that, the first part and the second part are attachable to each other by providing the first protruding portion through the auxiliary opening from a first side of the outer wall such that the first protruding portion is exposed on a second opposite side of the outer wall, and by providing the second part from the second opposite side of the outer wall such that the first fastening bore is aligned with the first protruding portion, allowing insertion of the fastening member from the second part to the first part.

Optionally, and when the outlet assembly comprises a first protruding support portion as mentioned herein, the outer wall further defines a wall bore with an opening, the wall bore extending from the opening of the wall bore in a direction along the outlet axis and from the first side of the outer wall towards the second opposite side of outer wall, the wall bore being located radially outside the wall opening and at least partly radially inside the auxiliary opening, and the first protruding support portion being configured to be received in the wall bore when the first part and the second part are attached to each other.

According to a third aspect of the disclosure, a method according to claim 1 is provided.

Thus, there is provided a method for arranging an outlet assembly according to any one of the embodiments of the first aspect of the disclosure to an outer wall of a dispenser for web-shaped absorbent material, the outer wall defining a wall opening extending along an outlet axis through the outer wall. The method comprises:

- moving the first part from an initial unattached state outside a first side of the outer wall towards the first side of the outer wall until the first protruding portion extends through an opening of the outer wall such that the first protruding portion is exposed on a second opposite side of the outer wall, and

- moving the second part from an initial unattached state outside the second opposite side of the outer wall towards the second opposite side of the outer wall until the first fastening bore is aligned with and proximate the first protruding portion.

Advantages and effects of the third aspect of the disclosure are largely analogous to the advantages and effects of the first and second aspects of the disclosure, and vice versa. It shall also be noted that all embodiments of the first and second aspects of the disclosure are applicable to and combinable with all embodiments of the third aspect of the disclosure, and vice versa. For example, by the method, a facilitated attachment procedure for a user may be achieved, which also provides a reliable and robust attachment to the outer wall of the dispenser. By way of example, by the configuration of the outlet assembly and/or the dispenser as disclosed herein, it may be easy to connect the first and second parts, especially when they have mating physical features so that it can be felt when they are correctly positioned in relation to each other. Further benefits may be attained when physical features such as auxiliary openings (or protrusions) in the dispenser wall are provided and which can cooperate with physical features on the parts of the outlet assembly to ascertain mechanical engagement between the parts of the outlet assembly and the dispenser wall. Symmetrical arrangement of physical features on the first and second parts of the outlet assembly may allow the outlet assembly to be mounted in more than one position at the opening in the outer wall of the dispenser which means that less concern has to be taken when positioning the assembly parts in relation to each other. For example, a small rotation of the parts in relation to each other may suffice to bring them into correct alignment.

The actions of the method may not necessarily be performed in the order as disclosed herein. In addition, some actions may be performed simultaneously, or at least partly simultaneously. For example, moving of the first and second parts may be performed in any order, simultaneously, or at least partly simultaneously.

Optionally, the outer wall further defines an auxiliary opening extending in a direction along the outlet axis through the outer wall and being located radially outside the wall opening, wherein moving the first part comprises moving the first part from the initial unattached state outside the first side of the outer wall towards the first side of the outer wall until the first protruding portion extends through the auxiliary opening such that the first protruding portion is exposed on the second opposite side of the outer wall.

Optionally, the method further comprises:

- inserting a fastening member from the second part to the first part.

Inserting the fastening member from the second part to the first part as disclosed herein may imply a safer configuration, avoiding unwanted removal of the outlet assembly from the first side of the outer wall, which first side may be an outer side of the dispenser. The insertion of the fastening member will firmly attach the first and second parts to each other.

Further advantages and advantageous features of the disclosure are disclosed in the following description and in the dependent claims.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS OF THE INVENTION

Fig. 1 depicts a non-assembled outlet assembly 1 in exploded view according to an example of the present disclosure. Fig. 1 also depicts a portion of an outer wall 30 of a dispenser 40 for web-shaped absorbent material. More specifically, an outlet assembly 1 for arrangement at a wall opening 31 in an outer wall 30 of a dispenser 40 for web-shaped absorbent material is shown. By way of example, the outlet assembly 1 may be denoted a nozzle. The outlet assembly 1 is for example adapted to ensure that web shaped absorbent material is separated, such as along perforation lines of the web shaped absorbent material, when dispensed. As such, the dispenser 40 may provide for one-by- one product dispensing of individual products. Additionally, or alternatively, the outlet assembly 1 may provide for continuous dispensing.

The outlet assembly 1 is adapted to form an outlet for dispensing of the web-shaped absorbent material from the dispenser 40 through the wall opening 31. The outlet assembly 1 comprises:

- a first part 10 defining a first outlet portion 12 having an extension along a centre axis X1 of the first part 10; and

- a second part 20 defining a second outlet portion 22 having an extension along a centre axis X2 of the second part 20.

The first part 10 comprises a first protruding portion 14 extending in a direction along the centre axis X1 of the first part 10 which is configured to receive and hold a fastening member (not shown). The second part 20 comprises a first fastening bore 24 extending in a direction along the centre axis X2 of the second part 20. The first fastening bore 24 is configured to receive the fastening member. The fastening member may be any type of elongated fastening member, such as a screw, a rivet, a pin, or the like.

In the shown example, two first fastening bores 24, 24’ are shown. In addition, in the shown example, three first protruding portions 14, 14’, 14” are shown. It shall however be noted that any number of first fastening bores and/or first protruding portions may be provided, such as one, two, three, four or five portions on each respective first and/or second part. It may be preferred to provide more than one location for attachments between the first and second parts 10, 20, such as the three attachment locations shown in Fig. 1. By providing more than one attachment location, stability of the attachment between the first and second parts 10, 20 may be improved, in particular if the attachment locations are evenly distributed around the periphery of the first and second outlet portions 12, 22. An even distribution of the attachment locations may also provide the benefit that there are more than one way of attaching the first and second parts of the outlet assembly 1 to each other, which contributes to making mounting of the outlet assembly 1 to the dispenser 40 quick and easy.

The first part 10 and the second part 20 are configured to be attached to each other by providing the first part 10 such that the first protruding portion 14 faces the second part 20 and by providing the second part 20 such that the first fastening bore 24 is aligned with the first protruding portion 14 to allow insertion of the fastening member from the second part 20 to the first part 10, and such that, when the first part 10 and the second part 20 are attached to each other, the first outlet portion 12 and the second outlet portion 22 form the outlet for dispensing of the web-shaped absorbent material from the dispenser 40 through the wall opening 31 in a direction along an outlet axis X.

As may be gleaned from fig. 1, the second outlet portion 22 of the second part 20 may be formed with a tapering shape which tapers in the direction towards the first part 10 when the second part 20 is attached thereto. For example, as depicted, the second outlet portion 22 may have a funnel shape which tapers towards the first part 10 when the second part 20 is attached thereto, thereby facilitating web-shaped absorbent material to be dispensed from the dispenser 40.

As further depicted in fig. 1 , the first part 10 may comprise a first protruding support portion 16 which extends in a direction along the centre axis X1 of the first part 10 and which is configured to be received in a wall bore 33 of the outer wall 30 when the first part 10 and the second part 20 are attached to each other. As shown, the first protruding support portion 16 may be located radially outside the first outlet portion 12 and at least partly radially inside the first protruding portion 14. For example, as shown in fig. 1 , the first protruding support portion 16 may be completely located radially inside the first protruding portion 14. A radial direction as used herein is a direction which intersects the respective axis which it refers to and which also is perpendicular to the respective axis.

For example, as shown in fig. 1, the first protruding support portion 16 may form an X- shape, viewed in a geometric sectional plane which is perpendicular to the centre axis X1 of the first part 10.

In the shown example, the first protruding support portion 16, i.e. , the X-shaped first protruding support portion 16, comprises a first wall member 164 which extends radially and a second wall member 166 which extends in a tangential direction with respect to the centre axis X1 of the first part 10. The radial extension of the first wall member 164 and the tangential extension of the second wall member 166 together form the X-shape. It shall however be noted that an X-shape may be achieved by two other wall members, e.g., wall members which are not extending in in the radial and/or tangential direction with respect to the centre axis X1. It shall also be noted that the two optional wall members may not necessarily form an X-shape, but other shapes are also feasible, such as an L- shape, H-shape, U-shape, J-shape, T-shape, etc, viewed in a geometric sectional plane which is perpendicular to the centre axis X1 of the first part 10. Forming the first protruding support portion 16 by two wall members as disclosed herein has shown to be beneficial when manufacturing the first part 10. For example, if the first part 10 is manufactured by injection moulding, the space for forming the first protruding support portion 16 can be filled efficiently. In addition, less material may be required for providing the first protruding support portion 16.

For example, as further shown in fig. 1, the first protruding portion 14 and the first protruding support portion 16 may be angularly offset by an angle a, as seen in a circumferential direction of the centre axis X1 of the first part 10, such that a first radially extending axis r1 which extends from the centre axis X1 of the first part 10 and midway through the first protruding portion 14 is angularly offset in the circumferential direction from a second radially extending axis r2 which extends from the centre axis X1 of the first part 10 and midway through the first protruding support portion 16. Thereby, by way of example, more available space for the two portions may be provided, implying a compact configuration.

For example, as further shown in fig. 1, the first part 10 may comprise at least two first protruding support portions 16, 16’, 16” arranged spaced apart from each other in a circumferential direction of the first outlet portion 12. In the shown example, the first part 10 comprises three first protruding support portions 16, 16’, 16”, each one being associated with a respective first protruding portion 14, 14’, 14”. The number of first protruding support portions 16, 16’, 16” may be equal to the number of first protruding portions 14, 14’, 14”.

For example, as further shown in fig. 1, the at least two first protruding support portions 16, 16’, 16”, may be arranged equiangularly from each other in the circumferential direction of the first outlet portion 12. In the shown example, the three first protruding support portions 16, 16’, 16” are arranged equiangularly from each other in the circumferential direction of the first outlet portion 12.

Fig. 2 depicts a perspective view of a first protruding portion 14 according to an example of the present disclosure. The first protruding portion 14 in fig. 2 may for example be the first protruding portion 14 as shown in fig. 1. As shown, the first protruding portion 14 may comprise a first tower portion 142 and a second tower portion 144 extending in a direction along the centre axis X1 of the first part 10, which first and second tower portions 142, 144 are separate with respect to each other such that they form a gap 146 therebetween configured to receive and hold the fastening member (not shown). The gap 146 may as shown preferably extend in a direction along the centre axis X1 and in a radial direction such that it defines a section which separates the first and second tower portions 142, 144. The gap also preferably has a width w1 , viewed in a tangential direction of the first protruding portion 14, as seen in a geometric sectional plane which is perpendicular to the centre axis X1 of the first part 10.

The fastening member to be received in the gap 146 may be a screw with screw threads, such as with cutting screw threads, wherein the first and second tower portions 142, 146 may be arranged to receive and hold, i.e. retain, the screw in the gap 146. For example, the gap 146 may comprise corresponding threads for the screw threads. Additionally, or alternatively, a screw with cutting screw threads may be retained in the gap 146 by plastic deformation of the first and second tower portions 142, 144 caused by the insertion of the screw with the cutting screw heads into the gap 146.

For example, as further shown in fig. 2, the first protruding portion 14 may have a maximum first length rmax in a radial direction and a maximum second length Tmax in a tangential direction, as seen in a geometric sectional plane which is perpendicular to the centre axis X1 of the first part 10, wherein the second length Tmax is greater than the first length rmax. In the shown example, the second length Tmax is at least two times greater than the first length rmax. This implies a compact configuration which also is able to reliably retain the fastening member in the gap 146 during use. For example, a greater second length Tmax may imply higher bending stiffness in the tangential direction. The higher bending stiffness in the tangential direction may in turn imply a more reliable connection with the fastening member. Figs. 3a-b depict an example of a second part 20 in perspective view according to the present disclosure. As shown, the second part 20 may comprise a second recess 28 extending in a direction along the centre axis X2 of the second part 20 which also is aligned with the first fastening bore 24. The second recess 28 is configured to receive a top portion 148 (see fig. 2) of the first protruding portion 14 when the first part 10 and the second part 20 are attached to each other. For example, the second recess 28 may have an extension in a tangential direction which corresponds to the second length Tmax such that the first protruding portion 14 snugly fits in the second recess 28. The extension in the tangential direction of the second recess 28 may be such that the first and second tower portions 142, 144 are prevented from flexing away from each other in the tangential direction by no more than a maximum length, when the fastening member is inserted therein. The maximum length may be very small, such as 1 millimetre or less, thereby mitigating the risk of the tower portions 142, 144 flexing away from each other. This may imply a more reliable attachment of the first and second parts 10, 20.

As may be further gleaned from e.g., fig. 3a, the second part 20 may comprise an outwardly facing peripheral surface 202 which encloses the second outlet portion 22 in a circumferential direction thereof, and the first fastening bore 24 may be located such that the fastening member, when being inserted into the first fastening bore 24, is at least partly located outside the outwardly facing peripheral surface 202. For example, as shown, the outwardly facing peripheral surface 202 may comprise a third recess 2022 extending in a direction along the centre axis X2 of the second part 20 which is aligned with the first fastening bore 24, allowing the fastening member to be inserted into the first fastening bore 24. As further shown, the third recess 2022 is preferably configured such that it does not interfere with the second outlet portion 22. This may imply a more reliable dispensing of the web-shaped absorbent material. For example, the third recess 22 may as shown be provided radially outside a funnel-shaped second outlet portion 22, i.e. , it does not interrupt the funnel-shape of the second outlet portion 22.

For example, as e.g., shown in fig. 1 and fig. 3a, the second part 20 may comprise at least two first fastening bores 24, 24’, preferably three first fastening bores, arranged spaced apart from each other in a circumferential direction of the second outlet portion 22. Typically, the second part 20 may comprise the same number of first fastening bores 24, 24’ as the number of first protruding portions 14, 14’, 14” of the first part 10. By way of example, the at least two first fastening bores 24, 24’, preferably the three first fastening bores, may be arranged equiangularly from each other in the circumferential direction of the second outlet portion 22, e.g., by 120 degrees from each other.

For example, as e.g., shown in fig. 1 , the first part 10 may comprise at least two first protruding portions 14, 14’, preferably three first protruding portions 14, 14’, 14”, arranged spaced apart from each other in a circumferential direction of the first outlet portion 12. Further, the at least two first protruding portions 14, 14’, preferably the three first protruding portions 14, 14’, 14”, may be arranged equiangularly from each other in the circumferential direction of the first outlet portion 12, e.g., by 120 degrees from each other.

For example, as may be gleaned in fig. 1 , the first protruding support portion 16 may comprise a radially inner support portion 162 extending in the direction along the centre axis X1 of the first part 10. As such, which may be gleaned in fig. 3b, the second part (20) may comprise a first recess 26 extending in a direction along the centre axis X2 of the second part 20 and which is located radially outside of the second outlet portion 22, and wherein the radially inner support portion 162 of the first protruding support portion 16 is configured to be received in the first recess 26 when the first part 10 and the second part 20 are attached to each other. In the shown example there are three such recesses for receiving a respective radially inner support portion 162, which recesses are arranged spaced apart from each other in the circumferential direction.

Figs. 4a-d show perspective views of a wall portion 30 of a dispenser 40 according to the present disclosure. Figs. 4a-d further shows an example of a method according to the present disclosure.

Accordingly, figs. 4a-d depicts an outlet portion of a dispenser 40 for web-shaped absorbent material comprising an outer wall 30 defining a wall opening 31. The wall opening 31 extends along an outlet axis X through the outer wall 30. The dispenser 40 further comprises an outlet assembly 1 according to an example of the first aspect of the disclosure, such as the outlet assembly shown in fig. 1. As may be gleaned in figs. 4a-d, the centre axis X1 of the first part 10 and the centre axis X2 of the second part 20 are aligned with the outlet axis X when the first and second parts 10, 20 are attached to each other. For example, as shown in e.g., figs. 4a-b, the outer wall 30 further defines an auxiliary opening 32 having an extension in a direction X0 along the outlet axis X through the outer wall 30 which is located radially outside the wall opening 31. The dispenser 40 may be configured such that the first part 10 and the second part 20 are attachable to each other by providing the first protruding portion 14 through the auxiliary opening 32 from a first side A1 of the outer wall 30 such that the first protruding portion 14 is exposed on a second opposite side A2 of the outer wall 30. An example of the exposed first protruding portion 14 is shown in fig. 4b, i.e. , the first protruding portion 14 may be accessible and at least partly provided on the second opposite side A2. The dispenser 40 may be configured such that the first part 10 and the second part 20 are attachable to each other by also providing the second part 20 from the second opposite side A2 of the outer wall 30 such that the first fastening bore 24 is aligned with the first protruding portion 14, allowing insertion of a fastening member 50 (see figs.4c-d) from the second part 20 to the first part 10.

For example, as shown in e.g., figs. 4a-b, the outer wall 30 may further define a wall bore 33 with an opening, wherein the wall bore 33 extends from the opening of the wall bore 33 in a direction along the outlet axis X and from the first side A1 of the outer wall 30 towards the second opposite side A2 of outer wall 30. Further, the wall bore 33 is located radially outside the wall opening 31 and at least partly radially inside the auxiliary opening 32, and the first protruding support portion 16 is configured to be received in the wall bore 33 when the first part 10 and the second part 20 are attached to each other.

In the shown examples, three auxiliary openings 32, 32’, 32” are depicted. In addition, in the shown examples, three wall bores 33, 33’ 33” are depicted. Accordingly, by way of example, if the first part 10 comprises three first protruding portions 14, 14, 14”, the outer wall 30 may have three corresponding auxiliary openings 32, 32’, 32”. In a similar vein, by way of example, if the first part 10 comprises three first protruding support portions 16, 16’, 16”, the outer wall 30 may have three corresponding wall bores 33, 33’, 33”.

The first part 10 and/or the second part 20 may for example be manufactured by injection moulding. For example, the first part 10 and/or the second part 20 may be made of a polymer material. With reference to figs. 4a-d, and also with reference to fig. 5 which depicts a flowchart, a method for arranging an outlet assembly 1 as disclosed herein to an outer wall 30 of a dispenser 40 for web-shaped absorbent material according to an example of the disclosure will be described.

The method comprises:

S1: moving the first part 10 from an initial unattached state outside a first side A1 of the outer wall 30 towards the first side A1 of the outer wall 30 (see fig. 4a) until the first protruding portion 14, 14’, 14” extends through an opening 32, 32’, 32” of the outer wall 30 such that the first protruding portion 14, 14’, 14” is exposed on a second opposite side A2 of the outer wall 30 (see fig. 4b).

The method further comprises:

S2: moving the second part 20 from an initial unattached state outside the second opposite side A2 of the outer wall 30 towards the second opposite side A2 of the outer wall 30 (see fig. 4b) until the first fastening bore 24, 24’, 24” is aligned with and proximate the first protruding portion 14, 14’, 14” (see fig. 4c).

The method may further comprise:

S3: inserting a fastening member 50 from the second part 20 to the first part 10. In the shown example, there are three fastening members 50 in the form of screws with screw heads. The screws 50 may be screwed into the first fastening bores 24, 24’, 24” by use a screwdriver (not shown).

As mentioned in the above, the outer wall 30 of the dispenser 40 may further define an auxiliary opening 32, 32’, 32” extending in a direction X0 along the outlet axis X through the outer wall 30 and which is located radially outside the wall opening 31 , wherein moving the first part 10 may comprise moving the first part 10 from the initial unattached state outside the first side A1 of the outer wall 30 towards the first side of the outer wall 30 until the first protruding portion 14, 14’, 14” extends through the auxiliary opening 32, 32’, 32” such that the first protruding portion 14, 14’, 14” is exposed on the second opposite side A2 of the outer wall 30.

Fig. 6 shows a perspective view of a dispenser 40 according to an example of the disclosure. For example, the dispenser 40 may comprise an outlet assembly 1 as shown in any one of figs. 1, 2, 3 and 4. As depicted, the first side A1 is typically an outer side of the dispenser 40. Accordingly, the second opposite side A2 is typically an inner side of the dispenser 40. It is to be understood that the present invention is not limited to the embodiments described above and illustrated in the drawings; rather, the skilled person will recognize that many changes and modifications may be made within the scope of the appended claims.
