GROUPABLE BAG FOR PACKAGING FRESH PRODUCE

Abstract

Disclosed is a bag that is produced continuously, forming a group of bags that occupy a minimum volume, the bags being individually detached from the group by means of precut lines, such that the bags are supported on dispensing means by means of upper and lateral sectors (10) delimited by precut lines (7), the tearing of which determines a handle (8) for the bag with the corresponding hole (9) thereof for inserting the fingers of a hand, the bag being separated from the lateral sectors (10). The bags have a bottom determined by three parallel folding lines that allow a W shape to be obtained, such that the bag is flat when not in use, incorporating a double-wall reinforcement at the level of the handle. The bag could optionally be produced using three bands, two end paper bands and a transparent intermediate band, fastened parallel to one another.

Claims

1. Groupable bag for packing fresh produce, comprising, a continuous sheet of paper with transversal die-cut lines defining a rectangular section with a longitudinal folding line that has corresponding folding lines on each side thereof, with said lines defining a W-shaped foldable bottom, as well as respective end longitudinal folding lines defining rectangular sections that are folded over said lines and glued using adhesive in order to define reinforcing elements, with the sections comprised between the folding lines defining the side walls of the bag and the side borders thereof bonding by means of glue lines, with the bag comprising pre-cut lines in correspondence with the upper borders of the side walls of the bag, so that tearing said lines defines a handle for the bag featuring an orifice for inserting the fingers of the hand, with the lateral sections featuring orifices for threading through hanging elements for distributing and separating the bags from a grouping of said bags.

2. Groupable bag for packing fresh produce according to claim 1, wherein the side borders of the bag are bonded by means of glue lines that can extend from one end of the side wall of the bag to the other.

3. Groupable bag for packing fresh produce according to claim 1, wherein the side borders of the bag are bonded by means of glue lines that can extend from one end of the side wall of the bag to the other, comprising a converging change of direction on the lower section thereof so that, when the bag is formed, the side walls thereof have a rectangular configuration with a lower section in the shape of an inverted isosceles trapezoid.

4. Groupable bag for packing fresh produce according to claim 1, further comprising lines of small orifices for ventilation, both in correspondence with the base and the lower border of the side walls thereof.

5. Groupable bag for packing fresh produce according to claim 1, wherein the continuous sheet used to create the product is a triple reel, with two end paper reels and one middle reel made of a transparent material, which are joined together longitudinally by means of adhesive.

6. Groupable bag for packing fresh produce according to claim 1, wherein the bag is fixed to other bags of the same type using adhesive applied between the lateral sections f of each bag.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] To complete the invention described below and in order to give a better understanding of the characteristics of the invention, according to a preferred embodiment thereof, this description is accompanied by a set of drawings in which the figures described below have been represented, for purely illustrative purposes and should not be construed as limiting:

[0015] FIG. 1.Shows a perspective view of a grouping of bags for packing fruit and vegetable produce designed according to the object of the present invention.

[0016] FIG. 2.Shows a plan view of the machine of one of the bags that is the object of the invention.

[0017] FIG. 3.Shows a perspective view of the bag of FIG. 2 when it is in use.

[0018] FIG. 3.Shows an embodiment of the bag of the invention that comprises a transparent section.

[0019] FIG. 5.Shows, finally, a perspective view of the bag of FIG. 4 when it is in use.

PREFERRED EMBODIMENT OF THE INVENTION

[0020] In light of the drawings detailed above, and particularly FIG. 2, we can see that the bag of the invention is produced from a paper reel that comprises continuous transversal parallel die-cut lines (1) defining a rectangular section that gives form to the bag when said lines are cut, with the reel also comprising a longitudinal folding line (2) that has corresponding folding lines (3) on each side thereof, with said lines defining a W-shaped foldable bottom, as well as respective end longitudinal folding lines (4) defining rectangular sections that are glued and folded inwards over said lines in order to reinforce the mouth of the bag at the level of the handle.

[0021] In this way, the sections comprised between the folding lines (3 and 4) define the side walls (5) of the bag, with the side borders thereof bonding by means of glue lines (6) that can extend from one end of the bag to the other, as in the example of FIG. 1 comprising a rectangular configuration, or alternatively, comprising a converging change of direction (6) on the lower section thereof so that the side walls of the bag have a rectangular configuration with a lower section in the shape of an inverted isosceles trapezoid when the bag is not in use, as shown on FIG. 3.

[0022] In either of the two cases and once the mouth of the bag has been reinforced by means of gluing the section defined by the end longitudinal folding lines (4), said border will comprise pre-cut lines (7) in correspondence with the upper borders of the side of the bag, so that tearing said lines defines a handle (8) for the bag featuring an orifice (9) for inserting the fingers of the hand, while the torn lateral sections (10) define means for dispensing and grouping the set of bags when they are not in use, featuring orifices (11) for threading hanging elements (12) through the stack of bags. This grouping of bags is possible thanks to the adhesive on the lateral sections (10) for holding the bag, which makes it possible to join the bags together to form a grouping, both when the bags are being transported as well as when they are hanging from these orifices (11).

[0023] Finally, the bag comprises lines of small orifices for ventilation (13), both in correspondence with the base and the lower border of the side walls of the bag, which are ideal for preserving fruit and vegetable produce, so that said orifices are made with a single manoeuvre since they are lined up when the bag is folded, which is what also happens with the die-cut lines defining the double wall handle and the orifices for hanging the bag.

[0024] Lastly, according to the example embodiment of FIGS. 4 and 5 and maintaining the same structure of the die-cut, folding and gluing lines described above, the continuous reel used to create the product could be formed by a triple reel, that is, three reels in parallel, with two end paper reels (P) and one middle reel made of a transparent material (C), which would be joined together longitudinally by means of adhesive, producing a bag comprising a transparent bottom and lower middle section of the side walls, while the upper middle section of the bag and the means for handling, grouping and separating the bag from the stack are made of paper.

[0025] It is worth clarifying that the set of bags designed according to FIG. 1 could be embodied without the lateral section (10), thus comprising a set of individual finished bags for immediate use.
