Definitions
- the present invention refers to a paper bag, of the type used to package fruit and vegetable products, such as grapes, without ruling out any other product, and which are supplied both in supermarkets and in large areas.
- the object of the invention is to provide a bag with a structure that allows it to be supplied in monobloc groups, in which a large number of bags participate in a minimum volume, being perfectly stabilized with each other, being easy to extract, deploy and use, all with a simple structure that minimizes manufacturing and handling costs.
- paper bags are known for packaging or transporting very different types of fruit and vegetable products, these bags have an "independent" character with respect to other bags of the same type, so that when large volumes of bags are to be supplied, these they tend to separate from each other, occupying more space, or causing, after the removal of one of them, the accidental fall of one or more bags from the support through which they are supplied.
- the grouped bag for the packaging of fruit and vegetable products solves the aforementioned problem based on a simple but highly effective solution.
- the bag of the invention is obtained from a reel of paper on which shrinking lines, folding lines and finally die-cut lines are applied continuously from which a plurality of bags are to be obtained. They will be linked together in the same stack with a monobloc character, from which the bags can be detached, through pre-cut lines, in a unitary way.
- each bag is obtained from a rectangular and transversal sector of the reel, and on which three longitudinal folding lines are established, one intermediate and two others close to each side of it, which delimit the lateral walls of the bag and a folding bottom in *W, so that after folding the bottom adopting said "W" configuration, adhesive is applied on the side edges of the side walls forming a body that is completely flat in an inoperative situation, but that can be unfold by virtue of the "W" configuration of its bottom, so that the line of adhesive provided on the side walls of the bag can extend from end to end of the same, or in its lower section extend through some converging fold lines in correspondence with the upper and lower ends of the two longitudinal fold lines that determine the lateral faces of the bag, so that the lateral walls of The bag has a rectangular configuration, with an inverted isosceles trapezoidal lower sector in an inoperative situation.
- the upper edges of the mouth of the bag extend into a rectangular sector, the same height as the handle, and which are folded over said mouth, adjoining by gluing, determining a double-walled handle, increasing the resistance of the bag.
- the side walls of the bag in correspondence with its free edge that determines the mouth of said bag, have cut and pre-cut lines in correspondence with the upper lateral edges of the bag, so that in the tearing of said lines a handle for the bag is determined, which will present a hole for the introduction of the fingers of the hand, while the torn lateral sectors determine the means of fastening and dispensing of the set of bags in an inoperative situation, incorporating holes for hanging the group.
- This grouping of bags is possible thanks to the presence of adhesive in these fastening areas, which allows the bags to be joined together, forming a group both at the time of transport and when hanging them for dispensing.
- the bag to incorporate rows of small ventilation holes both in correspondence with its base and on the lower edge of its side walls, rows of holes that coincide with each other when folded.
- Both the die-cuts that determine the handle, as well as the holes for hanging the bag in stacks, as well as the ventilation holes in the lower part of the bag, are made with the bag already formed and glued, in order to reduce the number of tools for necessary cut.
- the bag could be obtained from three parallel coils, two end coils of paper, and an intermediate coil of transparent material, which would be joined longitudinally to each other , so that the same structuring of the folding, gluing and die-cutting lines would be maintained, nevertheless obtaining a bag in which the bottom and the lower middle area of the side walls would be transparent, while the upper middle area of the walls of the bag, and the means of grasping, grouping and untying the stack would be made of paper.
- Figure 1 shows a perspective view of a group of bags for packaging horticultural products made in accordance with the object of the present invention.
- Figure 2.- Shows the plan development of one of the bags object of the invention.
- Figure 3. Shows a perspective view of the bag of figure 2 in an operating situation.
- Figure 4.- Shows a variant embodiment of the bag of the invention in which it includes a transparent area.
- Figure 5 - Shows, finally, a perspective view of the bag of figure 4 in an operative situation.
- the bag of the invention is obtained from a reel of paper on which parallel transverse die-cutting lines (1) are applied continuously. its cut determines a rectangular sector that will constitute the bag itself, as well as a longitudinal folding line (2) on each side of which two folding lines (3) determining a W-folding bottom are located in proximity, as well as two extreme longitudinal folding lines (4) that determine rectangular sectors that will be glued and folded on said lines internally, to reinforce the mouth of the bag at the level of the handle.
- the sectors between the fold lines (3 and 4) determine the side walls (5) of the bag whose side edges are fixed by gluing lines (6) that can extend from one end of the wall to the other. of the bag, as in the example of figure 1 with a rectangular configuration, or else undergo a change of direction (6') converging in its lower section, so that the side walls of the bag have a rectangular configuration, with an inverted isosceles trapezoidal lower sector in a situation inoperative, as shown in figure 3.
- pre-cut lines ( 7) in correspondence with the upper lateral edges of the bag, so that in the tearing of said lines a handle (8) is determined on which a hole (9) for the introduction of the fingers of the hand will be made, while the torn side sectors (10) determine the means for dispensing and grouping the set of bags in an inoperative situation, incorporating holes (11) for the passage of hanging elements (12) of the stack of bags.
- This grouping of bags is possible thanks to the presence of adhesive in the lateral fastening sectors (10), which allows the bags to be joined together, keeping them grouped both during transport and when hanging them through these holes (11).
- the bag incorporates lines of small ventilation holes (13) both in correspondence with its base and on the lower edge of its side walls, ideal for the conservation of fruit and vegetable products, so that these holes will be made in a single maneuver. when they are aligned when the bag is folded, the same happens with the dies that determine the double-walled handle and the holes for hanging the bag.
- the continuous band from which the product is obtained can be formed by a triple band, that is, from three coils in parallel, two extreme coils of paper (P), and an intermediate coil of transparent material (C), which would be joined longitudinally to each other by means of adhesive, obtaining a bag on the that the bottom and the lower middle area of the side walls would be transparent, while the upper middle area of the walls of the bag, and the means for gripping, stacking and untying the stack would be made of paper.
