TECHNICAL FIELD

[001] The present disclosure generally relates to a wrap for closing the top open housing of a primary container of a multipack, and further to a multipack for beverage containers comprising such wrap. ; More particularly it relates to a portable cooling multipack for cooling the beverage containers contained therein.

BACKGROUND

[002] Containers enclosing liquid foods such as for example, water, beer, beverages, etc. have lately been proved invaluable in a wide array of situations. For example, water containers have widely been used across the globe by the people during travel. Also, campers, hikers and backpackers use portable beverage containers for excursions in remote areas. These containers range from small sized portable containers to large size barrel shaped containers, depending upon the quantity of the beverage enclosed therein.

[003] Most of the beverages such as juices, beer, wines and others are preferably consumed when cold, ideally around 45°F for juices, and between 50°F to 60°F for wines. Therefore, in order to accommodate the various outdoor activities enjoyed by people today, it has long been known to utilize various portable ice receptacles to keep food and drinks cool while away from sources of power and refrigeration.

[004] To avoid the problem of breakage / damage of containers / bottles while transportation and to further enable a proper handling, there has been a many-fold increase in the trend of grouping large number of beverage containers together in the form of multipacks. Most of these include multipack cartons are made of paperboard and / or cardboard material. Further, there has further been many developments for keeping the containers stored within these multipacks in a ready to drink state, many multipack containers were designed to accept ice or other cooling means in order to chill containers in the package without having to use a separate cooling source.

[005] For example, U.S. Pat. No. 5,495,727. discloses an expandable package adapted to accommodate ice for facilitating chilling of the beverage containers stored within. Further, the package includes one or more drain holes for enabling a drainage of fluids formed due to melting of ice and due to any leakage from the beverage containers during shipment and handling. Additionally, the package includes a waterproof lining to prevent or substantially reduce leakage of liquids from within the package.

[006] U.S. Pat. No. 8,100,320. discloses a cooler carton for items such as beverage containers. The carton is formed by folding a carton blank in an erected configuration. The erected carton includes an inner space for holding beverage containers and a containment skirt that extends above the level of the containers stored within the carton. Ice can then be added atop the items to cool their contents and the ice is contained by the skirt. Gussets are formed at lower corner portions of the carton and, along with a moisture barrier, prevent accumulated water from leaking from the bottom region of the carton.

[007] However, various above mentioned multipack coolers, including others currently known carton-based multipacks have certain disadvantages which are common to the prior art in general. One prominent disadvantage in many of the prior art inventions is that the cartons or packages are structurally complex, and are, therefore, expensive to manufacture. Additionally, although many prior art devices are structurally complex, they are not configured in a reinforced manner to hold ice or water for long periods of time. Another disadvantage of many of the prior art devices is that cooled water from melted ice is allowed to drain away from the package, which minimizes the cooling effect of melted ice.

[008] To overcome above problems, there were formed several other multipack cooling containers which included various kind of ice chests. For example, one commonly used ice chest included a double walled metal container with the space between the walls filled with some type of insulation. Such ice chests were prevalent throughout the early part of the century and were used to a fair extent. However, these ice chest, or ice boxes as they were known, while presenting problems of both weight and bulkiness, were not configured to properly hold a group of containers together but randomly contained within the box and therefore had to be taken out individually. Additionally, these individually stored containers and / or bottles, were more prone to damage / breakage during the transportation and therefore were not preferred. To overcome this, a various kind of separator trays were designed to keep the beverage containers separated from each other, but still the problem of weight, bulkiness and the like were not resolved.

[009] Accordingly, as can be seen from the foregoing discussion, there still exists a need for an improved multipack for beverage containers / bottles which while being able to light weight and easy to handle, is strong, cost effective, and is well suitable to be used for carrying the beverage containers while cooling them.

SUMMARY

[0010] In an aspect of the invention, a closing wrap for closing the top open surface of the housing of a primary container of a multipack is provided, as well as a multipack for holding a plurality of beverage containers comprising such closing wrap. In particular, the multipack may be a portable cooling multipack. The multipack includes a primary container formed from an open top housing, having a bottom surface, and a plurality of sidewalls connected and extended away from the bottom surface to define an inner surface there between, accessible through a top open surface. The multipack further includes a closing wrap for closing the top open surface of the housing of the primary container. The closing wrap includes a plurality of panels defining a first end panel connected to a second end panel through a bottom panel at one end in a first direction and extending towards a top panel at another end in a second direction opposite to the first direction. In use, the closing wrap is wrapped around a pair of sidewalls of the primary containers in a vertical direction such that the top panel of the closing wrap sealingly covers the open top surface of the primary container.

[0011] A benefit of a wrap sealingly closing the open top surface of the primary container is that, when a user lifts the handle, or tries to move the multi pack in a way that the open top housing would typically compress and deform, the top panel acts as the sixth primary container wall, giving the structure much more strength that a typical open five- sided container with a wrap.

[0012] This wrap and using in this wrap in a multipack for beverage containers allows to use lightweight materials and to reduce raw material cost ombined with automation cost reduction.

[0013] Preferably, the beverage container is a bottle shaped container having a bottom surface extended towards a neck portion through a shoulder portion.

[0014] Alternatively, the beverage container is a can shaped container having a cylindrical body extended between a top surface and a bottom surface.

[0015] Possibly, the primary container may be made in the form of any suitable geometric shape selected from but not limited to a cuboidal, cubical, circular, hexagonal, and the like. [0016] Further possible, each of the plurality of sidewalls of the housing has a height substantially greater than the height of the beverage containers to be stored there within.

[0017] Potentially, the first end panel of the closing wrap is adapted to cover a first sidewall of the housing and extended in towards the second end panel adapted to cover a second sidewall opposite to the first sidewall, through the bottom panel adapted to cover the bottom surface of the housing. Further, the first end panel is extended in the second direction towards the top panel adapted to cover the open top surface of the housing of the primary container.

[0018] Further potentially, each of the panels of the closing wrap is shaped and dimensioned according to the shape and dimension of a corresponding surface of the housing of the primary container.

[0019] Yet further potentially, the second end panel further comprising a closing flap adapted to be complementary engaged with the top panel thereby locking the closing wrap onto the primary container.

[0020] Yet furthermore potentially, the closing flap is engaged with the top panel using an engagement mechanism selected from one or more of but not limited to glue-based affixation, notch-based engagement, adhesive strips, and the like.

[0021] Additionally, one or panels of the plurality of panels, and preferable the bottom panel of the closing wrap may include an adhesive patch adapted to adhere it onto the bottom surface of the housing of the primary container.

[0022] Optionally, the closing wrap includes a handle affixed / glued onto an outer surface of the top panel for facilitating gripping of multipack.

[0023] Further optionally, the handle includes an expandable gripping portion extending out of a pocket handle at each of its end such that when a user lifts the multipack the gripping portion stretches out and retracts back once released by the user.

[0024] Preferably, the top panel of the closing wrap is a multilayer structure having a top layer and a bottom layer, the bottom layer adapted to be faced towards the interior of the housing.

[0025] Further preferably, the bottom layer of the top panel includes a plurality of holes for supporting each of the beverage container at its neck portion.

[0026] Alternatively, the top panel of the closing wrap is a single layer structure. [0027] Further alternatively, the top panel of the closing wrap includes an insert adapted to be glued onto the inner surface thereof. This insert contributes to the strength of the structure by even more acting as a rigid sixth primary container wall and avoiding that the open top housing would typically compress and deform.

[0028] Optionally, the insert is a fluted / corrugated cushioning pad having a plurality of holes for supporting each of the beverage container at its neck portion.

[0029] Alternatively, the insert is a cushioning pad with no holes and adapted to stabilize the beverage containers from the top.

[0030] Generally, the closing wrap is made of a foldable carton blank formed of a material selected from one or more of but not limited to all kind of papers, fiberboard, paperboard, any hybrid material and the like.

[0031] Alternatively, the closing wrap may be made of a light-weight plastic material.

[0032] Potentially, the primary container may be made of a material selected from one of but not limited to an integrated molded plastic, a metal tin, a paper thermoform, and the like.

[0033] Further potentially, the primary container includes a layer of a heat-insulating material configured onto the inner sidewalls of the housing.

[0034] Possibly, the primary container comprising a plurality of spaced apart depressions configured onto the inner bottom surface of the housing.

[0035] Further possibly, each of the plurality of spaced apart depression has a depth ranging between 5mm and 30 mm and preferably between 10 mm and 20 mm.

[0036] Yet further possibly, each of the plurality of spaced apart depression has a shape and dimension complementary to a bottom surface of the beverage container so as to facilitate retaining a beverage container thereupon.

[0037] Optionally, the primary container includes one or more handle openings / elongated slots configured on a pair of opposite sidewalls thereof.

[0038] Further optionally, the handle opening is shaped to facilitate gripping of the container by user hands.

[0039] Possibly, the primary container includes one or more, optionally corrugated, spacer tray, each having a plurality of cutouts for horizontally supporting the plurality of the beverage containers together within the housing.

[0040] Further possibly, the one or more, optionally corrugated, spacer trays are arranged in a vertically spaced apart manner wherein further each of the (optionally corrugated) spacer tray is of a dimension same as the inner dimension at a point of contact with the housing. Note that in the above embodiment, one or more crosslinks may or may not be provided coupling the separate spacer trays while fixing the vertical separation thereof. The crosslinks can be provided in many forms, for instance as strips (of varying width, ranging from several mm to several cm, up to a majority of the length or width of the spacer trays themselves) or bars/pillars of material (cardboard, paper, thermoform, metal, plastic, etc.) connecting two layers of spacer trays at one or more positions (preferably symmetrically divided). In some embodiments, the crosslinks will substantially comprise the same material as the spacer tray, in others this will be different, depending on the needs and circumstances (for instance stronger crosslinks, crosslinks more resistant to humidity, heat, etc.). In certain embodiments, the separate spacer trays may comprise or consist of different materials, again depending on circumstances.

[0041] Yet further possibly, each of the plurality of cutouts have a diameter equal to a diameter at a position of the beverage container at a height corresponding to the point of contact between the spacer tray and the housing.

[0042] The closing wrap may further include an additional flap extending away from the closing flap and being adapted to be folded inwardly into the primary container housing, said additional flap putting pressure on the spacer tray to avoid that it moves upwardly in case the multipack is shaken during carrying or transportation. Said additional flap may be further adapted to interact with the spacer tray, for instance by providing protrusions that are positioned to correspond to the positioning of cutouts. As such, the protrusions may be partly introduced into the cutouts, further securing the wrap and spacer trays in their respective positions.

[0043] In a preferred embodiment, the packaging comprises a two-level spacer tray, which levels are vertically interconnected via a number of crosslinks, preferably the levels separated over a vertical distance of at least 2 cm, preferably at least 4 cm. We note that this embodiment is especially advantageous for multipacks for holding bottles. The specific shape of a bottle, and the variation in diameter between neck and body, allows the spacer tray to dimension its apertures through which the bottles fit, so that the lower aperture (that of the lower layer) allows the insertion of (at least part of) a body of a bottle, while the upper aperture (of the upper layer) is dimensioned to allow insertion of (part of) the neck section of said bottle while not allowing insertion of the body. This ensures that the spacer is delimited in its vertical movement downwardly, and remains suspended above the bottom of the primary container, thereby providing a double horizontal fixation of the held bottles (at body and at neck level). Particularly preferable, the wrap is adapted to have the additional flap as mentioned above, which can interact with the spacer tray and delimit its vertical movement in the upwards direction. As such, the bottles are entirely fixed.

[0044] Note that the above may or may not be combined with a dimensioning of the overall length and width of the spacer tray to 'fit' inside of a primary container with a decreasing size along its depth dimension (being smaller towards the bottom).

[0045] In another aspect of the invention, a method for assembling the multipack is disclosed. The method includes receiving one or more beverage containers within the primary container such that each of the beverage container is placed onto one of the plurality of spaced apart depressions configured on the bottom surface of the housing.. The method further includes vertically wrapping the closing wrap around a pair of opposite sidewalls of the primary container by folding the foldable blank such that the top panel of the closing wrap covers the open surface of the housing. The method further includes locking the closing wrap by engaging the top panel with the closing flap of the second end panel.

[0046] The method further includes attaching a handle onto the top panel of the closing wrap.

[0047] Optionally, the method includes gluing the bottom panel onto the bottom surface of the primary container.

[0048] Further optionally, the method includes gluing the insert on the inside of the top panel before closing the top panel.

[0049] In the case that the multipack is a cooling multipack, the method may include placing one or more cooling medium such as crushed ice, and the like within the primary container within the space between the plurality of spaced apart dimensions.

[0050] It should be noted that the invention expertly aims at separating functionalities of the two distinct parts of the packaging. The primary container being suitable for providing the necessary strength and support in holding the beverage containers therein, and is therefore sufficiently rigid and strong. In this light, the appropriate materials can be chosen, preferably lightweight such as aluminum, and the container itself can be adapted to fit the functionalities it is intended for, while leaving certain other aspects to the second part of the packaging. As such, for instance apertures can be provided at strategic places, which in themselves do not jeopardize structural strength, but can reduce weight (and material costs), allow aeration, allow liquid to drain out of the primary container, etc. Furthermore, decorations can be provided more easily on 'hard' support surfaces. A rigid primary container finally allows to stack the primary containers on top of each other without relying on the beverage containers held therein to provide sufficient support, as would be the case in the prior art embodiments. Even in embodiments wherein the base of the primary container is smaller than the open top, (and a higher placed primary container would then rest on beverage containers of the underlying primary container), this can be easily avoided by providing support plates between layers of primary containers, ensuring that the weight rests on the primary containers, whereas in such prior art as US 3,066,795 this still would rest on the beverage containers.

[0051] Accordingly, the second part of the packaging, the (foldable) wrap does not substantially contribute to the structural strength (aside from linking the tops of at least two opposite side walls, thereby avoiding compression or deformation). Therefore, other aspects can be considered when choosing material(s) and characteristics such as thickness, elasticity, resistance and the likes. It is for this matter that in a preferred embodiment, the wrap material at least comprises flexible material, such as cardboard, paper and/or plastic materials. The functionality of this wrap layer lies, amongst others, in covering the insides of the primary container, and sealingly closing it, thereby protecting the beverage containers within from outside influences (dirt, dust, water, etc.).

[0052] The applicant thus proposes a preferred embodiment, wherein the primary container is substantially rigid (i.e. at least the bottom and at least two oppositely positioned sidewalls, preferably all of the side walls). Under 'rigid', it is to be understood that the primary container sidewalls are suitable for supporting at least the weight of one other multipack according to the invention, filled with (full) beverage containers. Preferably, the primary container is suitable for supporting several times this weight, which can be accomplished by material choice and/or variation in material characteristics (thickness, form, etc.).

[0053] In a preferred embodiment, the wrap is substantially thinner than the walls of the primary container.

[0054] In a preferred embodiment, the wrap is waterproof, in the sense that it does not absorb or allow transit of water through it.

[0055] The details of one or more implementations are set forth in the accompanying drawings and the description below. Other aspects, features and advantages of the subject matter disclosed herein will be apparent from the description, the drawings, and the claims.

[0096] Fig. 6 with reference to Figs. l through 5, is a flow diagram illustrating a method 600 of assembling the multipack 100 of the present disclosure. The method starts at step 602 and proceeds to step 604 where the primary container 200 having housing 210 having a plurality of depression is formed from any predetermined method to receive a plurality of predetermined number of beverage containers 290. Thereafter the method proceeds to step 606 where a plurality of beverage containers is placed within the receiving portion 315 of the housing 310 such that each of the depression within the housing 210 receives one of the plurality of beverage containers 190. Once the containers are placed, the method 600 proceeds to step 608 where the one or more (optionally corrugated) spacers are installed within the primary container 200 such that each of the beverage containers is supported at a predetermined portion thereof. Preferably, two (optionally corrugated) spacer trays are installed, with one at the bottom of the housing and other at the neck portion such that any part of (optionally corrugated) spacer tray does not impact the packaging and labels of the beverage containers. Thereafter at step 612, the closing wrap 300 is installed over the housing 310 such that the top panel 311 sealingly covers the top open surface of the housing 310. Further, each of the plurality of holes is engaged with a corresponding beverage container at its neck portion. Thereafter, the method 600 proceeds to step 614, where the closing flap 300 is locked by locking the closing flap 318 onto the top panel 311 using the one or more engagement mechanism 318a. Further, in some embodiments, where the engagement mean 318a is an upwardly directed adhesive patch, as disclosed earlier, the closing flap 318 is folded down first to cover the top open surface 213 and thereafter the top panel 311 is closed onto the closing flap 318 such that it glues thereupon with the adhesive portion of the adhesive patch 318a Optionally, the method 600 may include an additional step 616 of attaching a predetermined handle [not shown] onto one of the top panel 311 of the closing wrap. In some embodiments, the optional step 616 may be performed either before the step 612 or after the step 612. Further, in the case the multipack is a cooling multipack, the method may have a step 610 where any known cooling medium is placed within the spaces between the plurality of beverage containers 290.

INDUSTRIAL APPLICABILITY

[0097] The present disclosure relates to a multipack 100 formed of a primary container 200, and having a closing wrap 300, enclosing and securely carrying container containing liquids, such as beer, wine, cider, hard liquor (e.g., distilled beverage, spirit, liquor, hard alcohol, etc.), soft drinks (e.g., cola, soda, pop, tonic, seltzer), iced tea, soda water and other types of carbonated / non-carbonated beverages. The multipack 200 while being cost-efficient and portable, is able to cool the beverage containers stored therein. Further, the multipack of the current disclosure is easy to be assembled by retail consumers, or by the retailers, and offers an easy yet comfortable shipping, handling and transporting of beverage cans of any shape, size or any variety of configurations. While the multipack 100 is described for holding and carrying beverage cans having a generally bottle shape, it is also contemplated for a person skilled in the art that the multipack 200 of the current disclosure may be implemented in various industries such as food industry, transport industry, house hold appliance industry in transportation of any kind of containers of any shape, size or any variety of configurations, without limiting it to the beverage industry.
