Description

So-called "folding bags" are commonly known as flat-woven shopping bags that can be folded up and then placed in a case - for the purpose of saving space when carrying them in a bag or handbag, etc. The case, which is often designed as a type of wallet, is intended to limit the dimensions of this "take-away package".

problem

The only real support for the folding process in these bags is the edges or folds that are pre-formed by pressing or ironing. After a few uses at the latest, the corresponding folding edge definitions, which are hardly effective in this way to begin with, are lost in the fabric surface and it becomes a game of patience to "stuff" the bag together in an almost even manner, let alone flat; the entire process is imprecise, time-consuming and complicated to handle, compared to its suitability for everyday use.

For bags with folding aids (e.g. edge weakening), the problem remains that a clean (external) edge flush is not ensured after the folding process.

invention

This problem is solved by the measures of claim 1.

Advantageous effects of the invention Once you know the folding sequence, folding the bag is child's play: The bag collapses or "folds" step by step on two fingers forming an axis, practically by itself, without the slightest thought being necessary about the accuracy of the fold. When folded, the bag automatically achieves perfect edge alignment thanks to the efficient folding edge definition and is actually super-flat after folding is complete, so that it can be carried around with hardly any bulk, even in a small shirt pocket, for example.

Further developments of the invention

Advantageous embodiments of the invention are specified in claims 2 to 5.

Further training according to requirements ensures a longer lifespan of the floor with frequent use.

The embodiment according to claim 3 represents a technically simpler, i.e. for the user also more favorable, application of the folding edge definition principle.

The embodiment according to claim 4 refers, among other things, to the transferability of the principle to pockets that are not rectangular in their basic shape, so there is no restriction in the geometry of the pocket.

Claim 5 represents general functional extensions of the lightweight folding bag, such as the possibility of storing a small shopping cart chip directly in a small additional compartment of the bag.

Description of the invention

Examples of embodiments are explained using Figures 2 to 4.

Show it...:

...Figure 2 shows the surface segment reinforcement by means of a coating (3), whereby this can be done on one or both sides.

...Figure 3 shows schematically the detail of the weaving solution for defining the fold edges in the surface cross-section.

...Figure 4 in the detail the economically inexpensive folding edge definition through well-placed perforation or recess.

Claims (5)

that the front, back and side surfaces (1) of the bag are "plating", i.e. individual surface segments (2) are either made stronger by coating on both sides (not shown) or one side (3) or by weaving (4) than the connecting surfaces (5) between them, or the connecting surfaces (5) are made weaker than the predominantly (actually) surface-forming segments (2), and that the handle (1a) is integrated into the surface (woven in without seams), and the bag is woven either on each front, back or side surface or in its entirety without seams from a single continuous piece or at least in one piece beyond individual parts (segment/handle/base), furthermore by the fact that the bag has (woven in) air holes for the easy escape of air during the folding process, and then with regard to the coordination of the area segments by that the edge overhangs that occur during each multiple folding process are already differentially subtracted and added in the calculation/dimensioning of the surface segments and connecting surfaces so that the surfaces are clearly flush with the edges when folded multiple times, as they are calculated in such a way that the surface segments on the inside after the folding or folding process are smaller by the overhang to be avoided, and the surface segments on the outside after the folding process are larger by the underhang to be avoided, as well as offset from each other by the original equality to be avoided (here: of four surface segments) in the plane and/or on the normal or/and, if necessary, on multiple sides per segment, the angle is reduced or increased by the difference between the actually right-angled surface edges and the shear angle at their original exit (= intersection between two connecting surfaces (6)) due to the material thickness, and by the material thicknesses of the segments being adaptively reduced or increased inwards or are woven on the outside (direction of the material thickness exiting the plane), and in the overall arrangement (edge lengths, segment offsets in the plane and on the normal, segment spacing, spacing angle, and symmetrical or asymmetrical direction of the material thickness exiting the plane) the interlocking of the front and back of the bag as well as other additional (e.g. bottom) sides that occurs during the folding or folding process is taken into account.

Folding bag according to claim 1, characterized in that that one side of the base has an abrasion-resistant rubber coating or coating (not shown), without being too bulky. 3. Folding bag according to claims 1 and 2,
characterized, that the weakening of the connecting surfaces (5) is carried out by (precisely) calculated woven, punched or welded (long) holes (7) and the connecting webs (8) thus created between the surface segments when folding or folding the bag from the respective inner folding edge (row of webs (8a)) through the respective outer fold adjacent to it (row of holes (7a) by the (total) distance of the material thicknesses , which alternatively replaces the calculated surface and thickness variations in whole or in part or is combined with them. 4. Folding bag according to claims 1 to 3,
characterized, that the basic principles of fold edge weakening or surface segment reinforcement are implemented in practical basic geometric shapes (e.g. honeycomb or hexagon segment, rectangle, triangle, etc.), and additional base surfaces or other integrated additional surfaces are incorporated. 5. Folding bag according to claims 1 to 4,
characterized, that the bag can also have additional functions such as a shopping cart chip, a slot for money, chip card, typical wallet and purse contents, ballpoint pens, etc. IFolgendeSeKe(protection claims):! | none
