Description

MULTI USAGE FOLDABLE BAG
FIELD OF THE INVENTION
The invention relates to multi usage foldable bags.
DESCRIPTION OF THE PRIOR ART
There are a large number of foldable bags that can be folded from a first state of use, in which they have a shape of a parallelepiped, into a second state of use in which they have an essentially planar shape.
This kind of bag usually comprises two walls connected by a bottom gusset and two lateral gussets.
When the bag is not used, the gussets can be folded so that the bag presents a generally planar shape.
When the bag is used to carry objects, the gussets can be unfolded and the walls put at a distance from each other, so that the bag adopts the shape of a parallelepiped.
One of the drawbacks of these bags is that it is very uneasy to use them to carry things when the bag is in its planar shape.
Firstly, an attempt to put an object in the bag when it is in its planar shape would most certainly unfold the gussets and make the bag to adopt its parallelepiped shape.
Secondly, the usefulness of the internal space of such a bag is limited by the presence of the gussets. Thus, this bag can be used efficiently only in one shape for transporting objects.

The lower central portions 123, 223, the first lower corner portions 106, 206 and the second lower corner portion 116, 216 are reinforced portions.
In a non-illustrated variant, other portions of the bag can be reinforced.
The reinforcement of some portions is a way to ease or facilitate foldings of the foldable bag. Also, the reinforcement of some of the basic portions can be a way to prevent the foldable bag to accidentally "switch" from one state to another state.
In addition, the foldable bag comprises detachment means
60, 70.
The foldable bag comprises a first detachment means 60 that extends at least along the first vertical edges 101, 201 between the top horizontal edge 124, 224 and the bottom horizontal edge 122, 222.
The foldable bag also comprises a second detachment means 70 that extends at least along the second vertical edges 111, 211, between the top horizontal edge 124, 224 and the bottom horizontal edge 122, 222.
The first and second detachment means 60, 70 both here extend at least from the top horizontal edges 124, 224 to the bottom horizontal edges 122, 222.
On one hand, the first detachment means 60 is designed to allow the first vertical edges 101, 201 to be unfastened and separated from each other.
Similarly, the second detachment means 70 is designed to allow the second vertical edges 111, 211 to be unfastened and separated from each other.
The first detachment means 60 does not only extend along the first 101, 201 edges, but also extends from the first corners of the walls 10, 20 along at least a portion of the bottom horizontal edges 122, 222.
Similarly, the second detachment means 70 extends along the first 101, 201 edges and also extends from the second corners of the walls 10, 20 along at least a portion of the bottom horizontal edges 122, 222.
Here, the first 60 and second 70 detachment means are zippers. In a non-illustrated variant, for example, the detachment means can be a plurality of snap fasteners.
The foldable bag comprises handling means 130, 230. At Figures 1 to 5, the handling means are two holes or cuttings 130, 230, each hole being formed in one of the walls 10, 20. In a variant illustrated at Figure 6, the handling means comprises two handles 130, 230, each handle 130, 230 being fixed on one of the walls 10, 20.
In addition, the foldable bag comprises attachment means 80 designed so that two distinct foldable bags can be fastened to each other at their top horizontal edges 124, 224. For example, the attachment means 80 can be used to create a "giant" tablecloth during a picnic event. The foldable bag is designed so that it can be used according to a plurality of states. The different states correspond to predetermined shapes of the foldable bag. Specifically, the foldable bag is designed so that its shape can be transformed from one of the predetermined shapes to another predetermined shape by using the folding lines to fold or unfold the foldable bag. Here, the different states comprise at least four states among which are :
- a non-folded bag state of use,
- a first folded bag state of use,
- a second folded bag state of storage, and
- a tablecloth state of use.
THE NON FOLDED BAG STATE OF USE
As it can be seen in Figure 1, when the foldable bag is in the non-folded bag state of use, the walls 10, 20 are planar or slightly planar.
In this state, each wall 10, 20 is totally unfolded. This means that none of the folding lines described above is used. It can be noted that the entirety of the inner face of the first wall 10 faces the entirety of the inner face of the second wall 20.
An internal space of the foldable bag is delimited by the entire inner faces of the walls 10, 20 and by the bag mouth 30.
The width of the foldable bag equals the length of the bottom horizontal edges 122, 222. The height of the foldable bag equals the length of the first 101, 201 and second 111, 211 edges. The depth of the foldable bag is close to zero before introducing items therein.
This non folded bag state is especially useful for transporting large substantially planar objects. THE FIRST FOLDED BAG STATE OF USE
As it can be seen in Figures 2 and 3, when the foldable bag is in the first folded bag state of use, the foldable bag has the general shape of a parallelepiped. In this state, the internal space of the foldable bag has a the shape of a parallelepiped and is delimited by the upper central portions 100, 200, the lower central portions 123, 223, the top first portions 104, 204, top second portions 114, 214 and the bag mouth 30.
The top first portion 104, 204, the top second portion 114,
214, the lower central portion 123, 223 of each wall 10, 20 are essentially orthogonal to the upper central portion 100, 200 of the same wall 10, 20.
It is to be noted that, when the foldable bag is in this first folded bag state of use, the lower portion 102b, 202b of the first vertical folding line 102, 202 of each wall 10, 20 is adjacent to, or in contact with, the first portion 121a, 221a of the folding line 121, 221 of the same wall 10, 20, and the lower portion 112b, 212b of the second vertical folding line 112, 212 of each wall 10, 20 is adjacent to, or in contact with, the second portion 121b, 221b of the horizontal folding line 121, 221 of the same wall 10, 20.
As it can be seen at Figure 2, the triangular portions of the two walls 10, 20 form two triangular extensions 40, 50 of the foldable bag.
On one hand, the first upper corner portions 105, 205 and the first lower corner portions 106, 206 of the two walls 10, 20 form together a first triangular excrescence 40.
On the other hand, the second upper corner portions 115, 215 and the second lower corner portions 116, 216 of the two walls 10, 20 form together a second triangular excrescence 50.
As it can be seen at Figure 3, the two triangular extensions 40, 50 can be fastened to the top first 104, 204 and top second 114, 214 portions of the walls 10, 20. For this purpose, the foldable bag comprises fixing means or fasteners. Here, the fixing means are snap fasteners 107, 207, 117, 217.
Specifically, each wall 10, 20 comprises here a first snap fastener 107, 207 and a second snap fastener 117, 217. The first snap fastener 107, 207 comprises a female snap, referred to as the first female snap 107b, 207b and a male snap, referred to as the first male snap 107a, 207a. The second snap fastener comprises a female snap referred to as the second female snap 117b, 217b, and a male snap, referred to as the second male snap 117a, 217a.
On each wall, the first male 107a, 207a and second male 117a, 217a snaps are located to be respectively fastened to the first 107b, 207b and second 117b, 217b female snaps. Particularly:
- the first male snap 107a, 207a is located on the lower section 104b, 204b of top first portion 104, 204,
- the second male snap 117a, 217a is located on the lower section 114b, 214b of the second top portion 114, 214,
- the first female snap 107b, 207b is located on the first upper corner portion 105, 205,
- the second female snap 117b, 217b is located on the second upper corner portion 115, 215.
The snap fasteners are located here on the outer face of each wall 10, 20.
When the bag is in this first folded state, the snap fasteners are designed to maintain the first and second corners of each wall 10, 20 close to, or in contact with, a facing portion of the same wall 10, 20.
The snap fasteners are designed to fasten the two triangular extensions 40, 50 of the foldable bag with facing portions of the bag. The first triangular excrescence 40 can be fastened with the snap fasteners to the top first portions 104, 204 of the walls 10, 20 and the second triangular excrescence 50 can be fastened with the snap fasteners to the second top portions 114, 214 of the walls 10, 20.
It should also be noted that when the foldable bag is in the first folded state, the width of the foldable bag equals the length of the central portion 121c, 221c of the horizontal folding lines 121, 221. The height of the foldable bag equals the length of the upper portion of the first and second vertical folding lines. The depth of the foldable bag equals the addition of the lengths of the first portion 121a, 221a of the horizontal folding line 121, 221.
THE SECOND FOLDED BAG STATE FOR STORAGE
As can be seen in Figure 4, the second folded bag state of the foldable bag is a storage state of the foldable bag. The outer face of the lower central portion 123 of the first wall 10 faces the outer face of the lower central portion 223 of the second wall 20.
When the foldable bag is in the second folded state for storage, the lower portion 102b, 202b of the first vertical folding line 102, 202 of each wall 10, 20 is adjacent to, or in contact with, the first portion 121a, 221a of the folding line 121, 221 of the same wall 10, 20, and the lower portion 112b, 212b of the second vertical folding line 112, 212 of each wall 10, 20 is adjacent to, or in contact with, the second portion 121b, 221b of the horizontal folding line 121 , 221 of the same wall 10, 20.
Moreover, the outer face of the first lower corner portion 106, 206 of each wall 10, 20 faces the outer face of the upper section 104a, 204a of the top first portion 104, 204 of the same wall 10, 20.
Similarly, the outer face of the second lower corner portion 116, 216 of each wall 10, 20 faces the outer face of the upper section 114a, 214a of the top second portion 114, 214 of the same wall 10, 20.
It should also be noted that when the bag is folded into its second folded state, the width of the foldable bag equals the length of the central portion 121c, 221c of the horizontal folding lines 121, 221. The height of the foldable bag equals the length of the upper portion of the first and second vertical folding lines. The depth of the foldable bag is close to zero.
Here, the foldable bag has a general shape that is roughly rectangular and planar.
THE TABLECLOTH STATE OF USE
As it can be seen in Figure 5, in this tablecloth state, the foldable bag is designed to serve as a tablecloth.
In this state, the first vertical edges 101, 201 and the second vertical edges 111, 211 of the walls 10, 20 are respectively detached separated from each other so that the foldable bag can be totally unfolded and opened. In that state, the walls 10, 20 are only fastened to each other by at least a part of the bottom horizontal edges 122, 222. The two walls 10, 20 can be arranged so that they are located in the same plane, for example on a planar surface or on the ground.
In a variant, the foldable bag comprises a unique detachment means that extends along the first vertical edges 101, 201, the bottom horizontal edges 122, 222 and the second vertical edges 111, 211. The two walls 10, 20 can thus be completely detached from each other and serve as two distinct tablecloths.
