Description

The present invention relates to a bag or a bag having a substantially closed bottom end and an opposite opening end, comprising a front side with an opening-side edge and a rear side with an opening-side edge, in the region of their side edges and bottom edges at least partially directly or through side walls and / or gussets and / or a bottom fold are connected to each other.

Bags and bags for transporting articles are known in the art. It is desirable that such bags and pouches can be easily opened, especially if there are no objects in them.

A bag may have a handle; wherein a bag has no reinforcement at or in the region of the handle. A bag basically has a handle, preferably with a reinforcement on or in the region of the handle.

The DE 10 2009 041 341 A1 describes an easy-open package comprising a plurality of layers and a non-thermoformed packaging element.

From the DE 201 01 296 U1 A plastic bag is known, the walls of which consist wholly or partly of at least two interconnected foils and which may comprise two holes within the foils arranged side by side, the pouches being suitable for packaging machines.

To save on manufacturing costs and for a more cost-effective transport, the material thickness of bags and bags is reduced further and further. In particular, thinner films are therefore used to produce such containers.

A disadvantage of the existing bags and bags is that they are difficult to open. For example, knot bags for fruits and vegetables are often provided in the form of an endless belt and / or rolled up to a customer. After tearing or removal of such a bag or such a bag must be opened for the introduction of the goods to be packaged. This is made more difficult, not only in the knot bags exemplified by ever thinner material thicknesses of the bags or bags. In particular, it is often difficult to open bags or bags with one hand.

Accordingly, it would be desirable to be able to resort to such bags or bags that are easy to open even with very small thicknesses and / or very thin films for producing such bags or bags for a user.

Accordingly, it is an object of the present invention to provide bags or pouches, in particular shipping bags or pouches or transport bags or pouches, which are free from the disadvantages of the prior art and which are easy to open.

The object of the present invention is achieved in that the front of the bag or the bag at least a first recess, in particular in the region of and / or formed by the opening edge and / or a side edge of the front comprises, and the back of the bag or the bag at least one second recess, in particular in the region of and / or formed by the opening edge and / or a side edge of the back, comprising, wherein the first and the second recess are offset from one another.

Under a recess in the context of the present invention, a recessed space to be understood. This can be understood in particular such that the front and / or back of a bag or a bag in this area no material, from wherein the respective side is formed, although a configuration of the bag or the bag in this area provides material.

By way of example, a recess in the sense of the present invention can be understood as meaning that a recess of the front releases at least in one section an arial of the rear side, and / or a recess of the rear releases at least in one section an arial of the front side. Also, a recess can be understood as meaning that the opening edge and / or a side edge of the front releases at least in one section an arial of the rear side and / or that the opening edge and / or a side edge of the rear side releases at least in one section an arial of the front side.

For example, and not by way of limitation, a recess may be provided by punching, cutting, and / or the like of material from a front and / or back of a bag or pouch.

In the area of one of the side edges and / or the opening edges in the sense of the present invention is intended to be understood as being both directly at the said edges and at a distance from them. In the area of one of the side edges and / or the opening edges, it can also include, for example, that a recess is arranged on the opening edge and / or on the side edge. At the side edge and / or the opening edge can be conveniently understood as a distance of a recess of one of the edges, in particular less than 10% of the longitudinal and / or transverse extent of the bag or the bag, or directly to the side edge and / or opening edge. Forming a recess through an opening edge and / or a side edge can be understood, for example, in the sense of the present invention, that a side edge and / or an opening edge is designed such that it provides a recess. For the purposes of the present invention, forming a recess can also be understood, for example, as meaning that the recesses form an integral part of an opening edge and / or side edge of a bag or pocket, in particular by subsequent provision of a recess in an existing opening and / or side edge ,

The terms front and back are to be understood as examples only and are intended to facilitate understanding of the invention. Of course it is for one It is obvious to a person skilled in the art that the side designated as the front side of a bag can also represent the rear side and vice versa.

An offset arrangement in the sense of the present invention is to be understood as meaning that the first and / or second recesses do not overlap completely congruently. This can be achieved in one embodiment of the invention, for example, by an offset between the recesses and / or by different geometric shapes of the recesses.

By arranged offset on the front and back of a bag or bag recesses can be achieved that a user engages with his fingers in the recesses. After the intervention in the recesses, these allow the front and the back to move against each other and thus open the bag or bag. Also, the edges of the recesses may be attack or friction points for mutually displacing manual manipulations.

It can be provided that a user rubs the front and back, in particular with one hand, against each other, ie laterally to each other. This is particularly advantageous if only one hand is to be used to open the bag or bag. An inventive bag or bag according to the invention can thus be opened in one-handed operation. After an opening of the bag or bag has been made to a certain opening width of the opening end of the bag or bag by such a lateral displacement of the front and back against each other, a user can for example with a finger in the bag or the bag between front and rear side engage and this open further, a desired opening width has not yet been reached.

By staggered recesses can thus be achieved that a user when moving the front and the back against each other to open is not affected by too low static friction of the surfaces of the front and / or the back of the bag or the bag. Rather, the edges or edges of the recesses allow the user even with very smooth and / or thin front and / or rear sides of bags a secure intervention in this for easier opening.

In principle, an increase in the static friction for a hand and / or a finger for opening a bag or a pocket can also be achieved by the opening edge protruding from the front or rear side of a bag or a pocket beyond the opening edge of the other side. Such a projection may provide easier gripping of a front and / or a back. However, such a configuration of a bag or a bag has the disadvantage that can be damaged in a filling of the bag or the bag in the region of the side edges, in particular tears.

As an alternative to rubbing the front and back of a bag or a bag against each other, a user can also open a bag or a bag according to the invention by intervening in the staggered recesses and pulling the front and the back apart. It can be made possible by the recesses a user to grab both the front and the back independently.

In one embodiment of the invention, it may be advantageous for the first recess and the second recess of the front or rear side to overlap only partially or not, wherein the first and / or second recess in particular comprises or forms a punched-out.

This may be advantageous in particular in order to allow a secure pulling apart of the front and back. In particular, in the case that opening of a bag or bag is to be realized by pulling apart the front and back, non-overlapping recesses may prevent a user from inadvertently gripping the front and back simultaneously and pulling in the same direction.

An only partial or no overlapping of the recesses may be advantageous in particular for opening a bag or a pocket by rubbing the front and back against each other. Are the recesses adjacent to each other, and not, for example, on each opposite side edges, so it can intervene with a hand in this, and the bag or the bag can be opened.

It can also be provided that the first and / or the second recess in the region of one of the side edges and / or the opening edge of the bag or the bag is arranged, in particular on one of the side edges and / or an opening edge, preferably comprising a portion of an opening edge of the Front and / or the back.

It may be advantageous according to an embodiment of the invention, when the recesses are arranged laterally on one of the edges of the bag or the bag. In particular, according to one of the embodiments, it can be advantageous if the recesses are arranged on the opening edge of the front and / or rear side.

With such an arrangement of the recesses opening the bag or the bag is particularly simple.

In particular, it may be advantageous that the first and / or second recess is circular, elliptical, and / or sinusoidal, in particular a semicircle, a semi-elliptical shape, a rectangular shape, a triangular shape, square, polygonal, and / or the shape a sine function with values from 0 to Π or from Π to 2Π.

Such a configuration of the recesses may be advantageous according to an embodiment of the invention, since especially in round or curved recesses particularly simple fingers of different sizes can be introduced.

In an embodiment of the invention, it may be advantageous for the first and / or second recess comprising a region of an opening edge of the front side and / or the back side to form a half ellipse whose main vertex, in particular substantially, along or spaced from the opening edge the front and / or the back extends and whose side apex extends in particular in the direction of the bottom end and / or a side edge of the bag or bag and / or the first and / or second recess comprising a portion or spaced from an opening edge of the front and / or or the back side forms a sine function from 0 to Π or from Π to 2Π, the zeros and / or inflection points of which are preferably along or spaced from the opening edge of the front side and / or the back side and the maximum of which extends in particular in the direction of the bottom end and / or a side edge of the bag or the bag.

It can also be provided that the longitudinal extent of the back, measured from the bottom end of the back to the opening end of the back, the longitudinal extent of the front measured from the bottom end of the front to the opening end of the front, preferably substantially corresponds, and / or that the Front and back, especially in the more essential, congruent.
