Description of the invention

The subject of the invention is a collective sleeve made of a single cardboard sheet cut out, intended for packing and carrying sets of individual packages.

Patent application No. 331,658 by the same applicant describes a bottle collection container made from a single sheet of cardboard or paperboard and bound with a tape, preferably polypropylene, comprising a cover with openings, extended on both sides by side walls, where one of these walls extends to a bottom, and the bottom is extended by a strip that is joined by adhesive to the other side wall, where each side wall consists of two panels separated by an overlap, with the panels partially overlapping one another. The overlapping panels, provided with appropriate pairs of teeth, create gaps in both side walls of the collection container, into which a tape is inserted, which wraps and tightens the entire container.

The technology of using a strapping tape is advantageous in the case of packing sets of individual packages with weight and dimensions exceeding the resistance of the cardboard to damage and tearing, but in the case of forming small and relatively light collective packages it is an economically unjustified technology and constitutes an inconvenience limiting the use of the invention described above.

Also known from patent application No. 332,792 by the same applicant is a transport sleeve designed for packaging and transporting sets of cans, jars, or bottles of beverages. It is made from a single sheet of cardboard or paperboard, comprising a lid, a bottom, and side walls with holes to stabilize the arrangement of the set of individual packages. According to the invention, this sleeve is also equipped with a flap located either in the lid or in one of the side walls. After being folded against the transport sleeve, the sleeve's circumference is reduced, and the packaged contents are clamped, the flap is secured using polypropylene tape, glue, a staple, or a sticker.

The disadvantage of using this solution is that all the methods mentioned above are intended to immobilize the folded tab relative to the transport sleeve. All of them require the use of an additional fastening element, which complicates the production process and increases its costs.

The invention aims to create a collective sleeve for packaging and transporting sets of individual packages that is free from the drawbacks outlined above. This goal is achieved by creating a sleeve made from a single cardboard sheet blank, the two ends of which are superimposed and joined with adhesive, containing holes to stabilize the position of the packaged set and at least one hole with a zipper ridge, as well as containing at least one flap bounded by two fold lines, wherein the flap is provided with a notch forming a zipper finger, the base of which is positioned on one of the fold lines of the collective sleeve.

Preferably, the second of the sleeve fold lines constitutes an axis of symmetry for the mutual positioning of the zipper ridge relative to the base of the zipper finger.

Preferably, the width of the zipper finger measured beyond its base is correspondingly greater than the width of the opening with the zipper back.

A bulk bag created according to the above invention includes at least one flap and one, two, or more zipper fingers and zipper-backed holes, positioned relative to the fold lines of the bag and forming snaps with which the bulk bag is fastened. After loading the bag with a set of individual packages and folding the flap, the entire bulk bag can be quickly and effectively secured by pressing the snaps, either manually or using an automatic fastening device.

The subject of the invention is shown in the embodiment examples shown in a perspective view in the drawing, where Fig. 1 shows the collecting sleeve in a simplified form before loading, Fig. 2 shows the collecting sleeve in an embodiment of a four-pack for cans before fastening the latch, and Fig. 3 shows the collecting sleeve in an embodiment of a four-pack for bottles after fastening the latches.

The collecting sleeve 1 (fig. 1) formed from one cardboard sheet blank, the two ends 29, 30 of which are superimposed and joined by means of glue, comprises at least one fold 11, delimited by fold lines 13, 14 provided with a cut 24 forming a locking finger 25, the base 26 of which is

PL 196 997 B1 located on the fold line 13, and the fold line 14 constitutes the axis of symmetry for the location of this base 26 in relation to the lock ridge 27 located on the edge of the opening 28.

The collecting sleeve in Fig. 2 shows the invention described above in an embodiment of a four-pack for beverage cans, where the collecting sleeve is additionally provided with holes 3. stabilizing the arrangement of the set of cans in the sleeve.

The collecting sleeve in Fig. 3 shows an example of a four-pack for bottles provided with stabilizing holes 3, two tabs 11 and two fastening clips.

The contents of the collective sleeve 1 are tightened by reducing the circumference of this sleeve caused by the fold of the fold 11 on the fold lines 13, 14. The elasticity of the cardboard causes the zipper finger 25 to automatically release from the notch 24 and, guided together with the fold 11 in relation to the axis of rotation defined by the fold line 14, to be applied to the opening 28 through which it is pushed into the interior of the sleeve and folded on the ridge of the zipper 27.

The fastening latch formed in this way provides a reliable and easy-to-use closure for the collecting sleeve. An additional safeguard preventing the latch from opening is the enlargement of the 25-inch width of the lock relative to the 28-inch width of the opening.

The cardboard collective sleeve, equipped with holes to stabilize the arrangement of a set of individual packages and easy-to-use latches, is a universal collective packaging, intended for widespread use not only in machine packaging technologies, but primarily for manual packaging, enabling the reuse of the same collective packaging when returning reusable individual packages.
