Description

Multiple pack wrappers

The present invention relates to a multi-pack sleeve container made from a perforated paperboard blank for wrapping or carrying bundles of consumer packages.

Description of related technologies

In the Polish patent international application PCT/PL97/00012 of the same applicant, there is disclosed an existing bottle packaging container for carrying filled bottles, which container is preferably made of glued cardboard, consisting of two symmetrical The carrying section is formed in which the wall is reinforced to form the middle part of the container, the middle wall has an imposed opening and is connected by a lock to form a handle, however each carrying section comprises at least one section with a cut away inner opening cut out ring having a front wing, wherein each of said carrier parts comprises, in addition to a middle wall, a bottom wall and an outer wall forming the exterior of the carrier, said outer wall being fixed to the front wing and by means of The ring is connected to the outer middle portion of each carrier portion. In addition, each outer wall has two symmetrically arranged holes, the voids being used for threading the polypropylene straps. The strap prevents bottles located on the outside of the carrier fastening ring from falling out of the carrier.

A disadvantage of the known prior art described above is the relatively high manufacturing costs of a container with a convenient handle and protection of its contents from tipping over on the outside and inside of multiple packages. The higher manufacturing costs required for such containers are due to the need for a precise bonding of the supporting structure. Furthermore, the through-hole design of the elements clamping the middle and the outside of the container presents some problems in bearing the mechanical loads of the consumer packaging, which leads to a high rate of damage to the plate structure.

A prior simplified multiple packaging container is disclosed in utility model patent application W-109211 filed with the Polish Patent Office by the same applicant. The container takes the form of a cardboard sleeve bound with polypropylene tape for packaging and carrying bundles of consumer packages such as boxes, cans, bottles and the like. A plurality of packaging containers stamped from a one-piece cardboard blank or the like, superimposed on its two ends and connected to each other by bonding, the container comprising a top, a bottom and two front walls, wherein Each front wall extends beyond the sides along the fold line to form two bars. Midway along the length of each of said fold lines there is a hole edged against a polypropylene band binding the plurality of packaging containers.

A disadvantage of this simplified prior art solution is the opening of the tightly fitting sleeve for the package. While the tight fit of the sleeve openings for bundles of consumer packages prevents them from moving freely relative to each other, providing a tight fit of the sleeve openings will result in the consumer packages not being quickly loaded into the cardboard sleeve. This would clearly hamper packaging automation using containers of this design.

There are also known packaging containers having cardboard strips designed for packaging and carrying bundles of consumer packages stamped from one integral cardboard blank or the like and superimposed on it The two ends of the blank are connected to each other by a bond or a lock, wherein the two ends of the blank are cut with a locking edge at one end and a locking wedge at the other end, and the two ends are cut by a The straps are fastened together.

The disadvantage of this prior art solution is that only lighter and smaller bundled consumer packages can be used which form the usual four or six can or bottle beverage packages on the market. The downside is that it lacks comfort and tight binding and tends to tear apart while carrying it.

Another disadvantage of this prior art solution is that packaging bundled consumer packages on cardboard blanks requires certain technical factors such as suitable machinery and strong cardboard stiffness. The packaging process requires the use of automatic gluing machines, or equipment equipped with specially designed locks to close the cardboard strips. All of this for an automated packaging process and the equivalent expense is an economic evaluation of whether the commercial scale is sufficient to return the investment associated with the purchase of special machinery and equipment.

Detailed description of the preferred embodiment

A multiple wrapper container for packaging and carrying bundles of bottles in an embodiment of the invention is formed from a perforated cardboard blank or the like (FIG. 1) comprising a top 2 with regularly spaced holes 3, The top 2 extends across two fold lines 4 to form two side walls 5, one of which extends across a fold line 6 to form a bottom 7 which extends across a fold line 8 to form the other side wall by bonding to a cardboard blank. 5 fixed strips 9 .

Each side wall 5 is formed by a flat section 10 separated from the fold 11 by a fold line 13 , and a flat section 12 separated by a fold line 14 .

The planar section 10 suitably has two jaws 15 with cutouts 16 and the planar section 12 suitably has two jaws 17 with cutouts 18. The jaws 15 and 17 and the cutouts 16 and 18 surround the side walls. 5 sides are set symmetrically.

As shown in Figure 3, the sleeve container of the multi-pack bottle pack forms an endless band 1, each fold 11 being folded between planar sections 10 and 12, jaws 15 and 17 having cutout sections 16 and 18 Suitable symmetrically arranged cut-out portions are formed into which straps may be inserted for binding around the sleeve container of the entire multi-pack bottle pack.

The multi-pack sleeve container of the bottle pack is stored in the form of a punched cardboard blank folded in half along the fold lines 4 and 6 and secured with adhesive along the strip 9 and the edge of the corresponding side wall 5 .

The multi-pack sleeve container of the bottle pack forms a three-dimensional structure by opening the folded corners along the fold lines 4 and 6 and closing the angles along the fold lines 4 and 8 ( FIG. 2 ) at the same time. A multi-pack sleeve in the form of a loosely rigid ring 1 is then used to pack the bottles, the bottles arranged in bundles being placed on the bottom 7 of the multi-pack sleeve.

The container packed with the bottle is closed tightly by pressing each of the two folds 11 against the flat section 10 and then pressing the folds 11 together with the flat section 10 against the flat section 12, so that the flat sections 10 and 12 form the side walls 5 by overlapping each other and shorten the length of the two folds 11 ( FIG. 3 ).

At the same time, when the folds are depressed, the top 2 of the container descends, so that the necks of the bottles contained in the multi-pack sleeve enter the opening 3, where the bundled bottles in the multi-pack sleeve The bottle is clamped by the falling top 2.

The final stage of the packaging process of the multi-pack sleeve container is the overall fastening with strapping, preferably polypropylene strapping, which is usually stretched and its ends welded together in an automatic machine. In this operation, the strap is inserted into the cut-out portion of the side wall 5 , into the cut-out portion formed by the partially overlapping planar sections 10 and 12 relative to the fold 11 . The straps that wrap the sleeves of multiple packages in a horizontal plane also act simultaneously to press the flat section 10 against the folds 11 and the strong folds 11 against the flat section 12 and the flat section 12 against the package. The locking action on the bundled bottles prevents the vertically fastened cardboard sleeves from loosening. Lashing straps, especially polypropylene straps, due to their mechanical properties, elasticity, inextensibility and high tensile strength, are also used as handles for sleeved containers of multiple packages, enabling the packaged containers to be easily and safely removed from the Move from one place to another.

The sleeve container of the multipack bottle pack can be easily opened by tearing off the top 2 without cutting the binding band. These orientations for opening the sleeve container further facilitate the use of the container which can be returned together with the returnable bottle so that it can be collected, stored and transported more easily. The empty bottle can be put back into the same opened sleeve container and returned to the point of sale as a compact bottle package with a secure handle. New strategies based on the reuse of multiple packs of cardboard are particularly environmentally friendly. Commercial-scale production of these packages, not only for bottles but for other cans, would eliminate the use of packaging and plastic boxes with polypropylene surfaces, which are not recyclable And cannot be biodegraded.

Another embodiment of the present invention is a multipack sleeve container (FIG. 4) designed for packaging and carrying bundles of beverage cans, the container being formed from a punched cardboard blank or the like, which includes a top 2 , the top 2 extends across two fold lines 4 to form two side walls 5 with holes 3, wherein the side walls 5 extend across fold lines 6 to form two planar sections 12, which suitably have two A jaw 17 with a notched portion 18. These two planar sections 12 form the base 7 when glued together. The top 2 is composed of two flat sections 10 and a fold 11 , wherein the fold 11 is separated from the flat section 10 by a fold line 13 . The flat section 10 expediently has two jaws 15 , each with a cutout 16 , which are arranged symmetrically around the two sides of the top 2 .

The multi-packed sleeve container shown in Figure 4 is tightly closed by clamping the folds 11 between the planar sections 10 when the cans are packed into bundles and the containers are tied tightly by a binding strap, which binds The straps are preferably polypropylene straps and are inserted into the bottom 7 and top 2 notches. The notch of the top 2 is formed by a partially overlapping planar segment 10 with respect to the folds 11 and is separated from the side walls by two pairs of jaws 15 with cutouts 16 , whereas the cutouts in the edge of the bottom 7 are by parts Overlapping planar sections 12 are formed and separated from the side walls by two pairs of jaws 17 with cutout portions 18 .

The overlapping folds 11 and flat sections 10 of the top 2 of the sleeve container of multiple packages can be bonded together by adhesive without the need for strapping, especially where the cans are stacked in one or two packs. case.

A specific embodiment of the multi-pack sleeve container of the present invention is a container for packing nine or twelve jars, which needs to be bound with polypropylene strapping. One such container is used in the express packaging process, where the three-layer bundle of cans is wrapped in an unfolded cardboard sheet, and the two ends of the sheet are glued together in an automatic gluing machine. The container is formed from a cardboard blank or the like with punched holes and comprises a top 2 which extends across two fold lines 4 to form two side walls 5 which have holes 3 through which the side walls 5 pass The fold line 6 extends to form two planar sections 12 which, when glued together, form the bottom 7 . The edge 20 of the top 2 and the edge 20 of the bottom 7 suitably have two pairs of notches 21, with each notch 21 located on half the length of the edge 20 of the top 2 and the edge 20 of the bottom 7, each notch 21 having Two jaws 15 with cut-out portions 16 adapted to receive straps 22 .

The multi-pack sleeve container described above in an embodiment of the invention is particularly suitable for packaging bundled consumer packages having a three-row gang arrangement transverse to the edge of the cardboard blank and parallel to the plane of the polypropylene tape-bound container.

The two outer layers of the consumer package are held by forces properly distributed inside the openings on both sides of the container by the pressure exerted on the side walls, so that they are secured in the appropriately shaped openings in these walls, due to the fact that the packaging It is generated by the external pressure exerted by the middle layer, which is effectively prevented by the binding of the polypropylene strapping tape. The stability of this arrangement is ensured by the binding strap, which is fixed on the cut-out part of the container, lying on the axis of symmetry of the three-row bundle and in the same plane.

According to the present invention, narrow polypropylene strips are used as strapping straps for three-row packing sleeve containers to considerably reduce packaging costs for cans or bottles packed in multiple bundles, and for ease of delivery. Direct sale on stage. The three-row loading sleeve container proved to be the lowest cost and most functional package in the paperboard multipack market.

Another embodiment of the present invention provides a multi-pack sleeve container that is snap fastened without adhesive or strapping.

The multi-pack sleeve container (FIG. 5) is formed from a punched cardboard blank or the like, the two ends 29, 30 of which are overlapped and fixed together with adhesive, comprising at least one of the fold lines 13 and The fold 11 defined by 14 has a notch 24 forming a locking wedge 25, the bottom 26 of which rests on the fold line 13, which constitutes a lock for this bottom 26 to coincide with the edge of the hole 28. Axis of symmetry for wedge positioning.

The wrappers of the sleeves of multiple packages are clamped by folding down the folds 11 along the fold lines 13, 14 to shorten the sleeves. Because of the elasticity of the cardboard, the locking wedge 25 protrudes upwards from the blank along the cut 24, corresponding to the axis of rotation determined by the fold line 14, moving together with the fold 11 towards the locking wedge 27, which moves to Above the hole 28 , the sleeve container is pushed and folded inwardly over said locking wedge 27 to pass through said hole 28 .

The resulting snap lock thus constitutes a reliable and simple fastening of multiple wrapping containers. An additional security against disengagement of the hasp lock from the opening is achieved by making the locking wedge larger than the width of the hole 28 . Once the multi-pack sleeve is packaged into a bundle of consumer packages and the pleats are folded, the multi-pack sleeve can be quickly and efficiently secured by pushing the locks or by manual or automatic fastening machines.

While pointing out the aforementioned embodiments of the invention, the variety of possible applications by the applicant and the variety of materials can be adapted to manufacture new containers. In particular the use of corrugated cardboard as a different plywood can be applied for the invention of packaging large-sized and/or heavy products, the use of strapping, preferably polypropylene tapes, enables such locking packaging Easy and safe transport.

The multipack sleeve container of the present invention is a new versatile invention, suitable for both commercial and small craft scales.
