Description

Title of the invention: Folding shopping bag FIELD OF INVENTION

[0001] The present invention relates to a folding shopping bag composed of a first panel and a second panel joined together, the two lateral sides and the bottom of which are connected by gussets to be folded flat, panel against panel and, if necessary, folded again, the bag having, in the unfolded state, a parallelepiped volume shape. STATE OF THE ART

[0002] Such folding shopping bags are known. They have the advantage of being very practical for shopping because they fold and unfold easily to have a reduced bulk and unfold to receive products while maintaining an overall parallelepiped shape facilitating the gripping and transport of the loaded bag, held by its two handles connected respectively to one and the other panels forming the bag.

[0003] But, such a bag cannot be easily closed and constitute a volume isolated from the outside, in particular, a volume thermally insulated from the outside.

[0004] Indeed, the load deforms the bag or at least does not allow the upper edges of the two panels to be brought together to close the volume and insulate the objects to protect them or maintain them at a certain temperature.

[0005] For such products, thermally insulated bags are used, which generally have very flexible walls. Such bags do not fold easily, but crumple into a shape that remains bulky.

[0006] However, these deformations deteriorate the thermal insulation properties. Furthermore, this insulating bag must be available at the same time as the general-purpose bag.

[0007] PURPOSE OF THE INVENTION

[0008] The present invention aims to develop a folding shopping bag, diversifying the storage capacity and which, in particular, allows certain products to be stored and isolated during their temporary storage in the shopping bag, and to separate them from the other products in the bag, without changing the overall size of the bag while being a single bag both in the folded and unfolded state and in the unfolded and loaded state.

[0009] DESCRIPTION AND ADVANTAGES OF THE INVENTION

[0010] To this end, the invention relates to a folding shopping bag comprising: a first panel and a second panel whose side panels and base are connected by gussets so that they can be folded flat panel to panel, and, if necessary, be further When folded, the bag, when unfolded, has a parallelepiped-shaped volume; the bag is characterized in that at least one of the panels is lined with an auxiliary panel, connected to the lateral edges of the first panel.

[0011] - an auxiliary bellows connecting the bottom edge of the associated panel to the auxiliary edge bottom edge of the auxiliary panel, and a bottom bellows connecting this bottom auxiliary edge to the bottom edge of the other panel.

[0012] In particular, the two lateral bellows directly connect the respective pairs of lateral edges of the two panels.

[0013] According to another feature, the upper edge of the first panel associated with the auxiliary panel and the upper edge of the latter form a closing line to access the compartment delimited by the associated panels and the auxiliary bellows.

[0014] Combining an auxiliary panel with one of the two panels allows for the creation of a separate compartment, isolated from the main volume; this combination allows the compartment to be closed to effectively isolate it from the environment, in particular, if the main panel and the associated auxiliary panel as well as the auxiliary bellows are made of a thermally insulating material or coated with such a material.

[0015] The close combination of the main panel to the auxiliary panel by the side edges makes the auxiliary panel perfectly suited for folding the gussets, to apply the two panels of the bag against each other with the interposition of the auxiliary panel; this also allows this assembly to be folded to reduce the bulky surface area accordingly.

[0016] According to another particularly interesting feature, the first panel lined with the auxiliary panel is made of a thermal insulation material at least on its face turned towards the auxiliary storage compartment, the auxiliary panel is made of a thermal insulation material at least on its face turned towards the first panel, and the auxiliary bellows is made of a thermal insulation material.

[0017] In addition, the insulating compartment is always available with the bag because it is integrated into the whole of the bag without this combination being bulky when only the non-insulated part is used.

[0018] If this compartment is not used, it remains flat and does not encumber the main volume of the bag, nor does it hinder the folding of the bag.

[0019] According to another feature, the upper edge of the first panel associated with the auxiliary panel and the upper edge of the latter form a closure line to access the compartment delimited by the associated panels and the auxiliary gusset, which makes it possible to produce, in a simple and efficient way, a bag with good stability when empty and when loaded.

[0020] The combination of the lateral edges of the bag and the associated auxiliary bag makes it possible to create a closure line that is not subjected to the transverse forces generated. due to the weight of the bag which pulls on the first and second panels and on the gussets not allowing the overall closure of such a bag.

[0021] The deployment of this compartment is limited by the auxiliary gusset which promotes the stability and support of the entire folding bag.

[0022] According to another advantageous variant, the second panel is also combined with an auxiliary panel to form another storage compartment, isolated within the overall enclosure defined by the two panels and the two side bellows.

[0023] The assembly of the panels and bellows is advantageously protected if the side edges and bottom edges are reinforced by tapes covering the edges of the assembled elements and integrated into the means of assembling the edges of the panels in particular a seam.

[0032] DESCRIPTION OF EMBODIMENT METHODS OF THE INVENTION

[0033] Figure 1 shows the folding shopping bag according to the invention, composed of a first panel 1PA and a second panel 2PA connected by overlapping side gussets SFL, and a bottom gusset SFF alongside panels 1PA and 2PA to create a folding shopping bag. When folded, the two panels overlap by compressing the gussets SFL and SFF to reduce the overall size to only the surface area of ​​the overlapping panels, which can be further reduced by folding it once or twice to divide the surface area by 2 or by 2 x 2.

[0034] In the unfolded and deployed state, the shopping bag 100 delimits a parallelepiped volume between its panels 1PA, 2PA and its side gussets SFL forming the side panels of the bag.

[0035] Bag 100 has an auxiliary PAX panel associated with one of the 1PA, 2PA panels to which it is connected.

[0036] This 1PA panel will be called the main 1PA panel to distinguish it from the other PAX panel without this designation implying any possible difference between the first and second panels.

[0037] The auxiliary PAX panel is connected to the main 1PA panel by:

[0038] - its sides attached to the sides of panel 1PA, and

[0039] - its upper edge BSX connected to the upper edge IBS of panel 1PA by a line LF closing;

[0040] - the lower edge of the first panel 1PA is connected to the first edge of a bellows auxiliary SFX forming the first bottom edge 1AF and by the second edge of the auxiliary bellows SFX connected to the lower edge of the auxiliary panel PAX thus forming an auxiliary bottom edge AXF to which is connected the first edge of the bottom bellows SFF; the other edge of the bottom bellows SFF is connected to the lower edge of the other panel 2PA thus forming the second bottom edge 2AF of the bag.

[0041] The folded ends of the auxiliary bellows SFX are integrated, folded respectively, into the two sides of the main panel 1PA in the two lateral edges 1AL. The auxiliary bellows SFX thus occupies the height H of the folded bellows SFX, in the two lateral edges 1AL of the main panel 1PA.

[0042] In this embodiment, the edges 1AL delimiting the edges of the panel 1PA are reinforced and stiffened by assembly at each of these two lateral edges 1AL:

[0043] - the two respective pairs of edges of the main panel 1PA and the panel PAX auxiliary

[0044] - the ends of the auxiliary bellows SFX partly in each of the two edges 1AL.

[0045] The lower edge of the panel is reinforced by its assembly to the edge of the bellows SFX, which is stiffened among other things by the integration of its two folded ends into the lower part of the lateral edges 1AL.

[0046] The transverse folding of the flattened bag 100 can also be easily done at mid-height by a transverse fold located above the lower part stiffened as described above by the bottom gussets SFF and FSX and the height H stiffened by the lateral edges 1AL.

[0047] At the top, the 1PA, PAX panels are connected by a closure line LF consisting of a zipper or micro-claw strips or other separable assembly means such as snap fasteners.

[0048] The combination of the two panels 1PA, PAX forms a compartment separate from the rest of the bag's volume and unfolds within the bag's volume delimited by the walls comprising the two panels 1PA, 2PA and the side gussets SFL. The bag 100 thus forms a parallelepiped-shaped volume, easy to carry thanks to its two handles 110, as it does not protrude laterally with bulky and cumbersome protrusions.

[0049] The compartment formed by the panels 1PA, PAX and the gusset SFX can hold products to be separated or isolated from other products placed in the bag.

[0050] According to one embodiment, the 1PA and PAX panels are made of a thermal insulation material, at least on the inner face facing the compartment. The same applies to the auxiliary bellows SFX so that the compartment can receive products to be insulated during the period of use of the bag 100.

[0051] The material of the panels and gussets is that generally used for such shopping bags having a certain firmness or rigidity, but accepting folding and allowing easy maintenance (washable).

[0052] Fig. 1 shows the parallelepiped outline of the unfolded bag with the folding lines PSFL, PSFF of the bellows SFL, SFF and the common edge AXF to the bottom bellows SFX, SFF.

[0053] The side view of [Fig.2A] shows the external shape of the bag 100 with the side gussets SFL deployed, also outlining the folding of the bottom gusset SFF.

[0054] Comparison of the side view of [Fig.2A] and the sectional view of [Fig.2B], according to the section plane II-II, (which does not pass through the lateral edges 1AL but in an intermediate position) shows that the bottom of the panel 1PA bulges outwards according to the deployment of the auxiliary bellows SFX while the top of the compartment is closed and the panels 1PA, PAX are brought together, connected by the closure line LF.

[0055] The [Fig.2C] which is a perspective view cut along the cutting plane (II-II) of the [Fig.1] shows the slightly deployed shape progressively of the auxiliary bellows SFX from its completely crushed, flattened form of its part integrated on its height H in the main lateral edge 1AL.

[0056] Figure 3 shows the bag 100 lying flat, with the gussets SFX and SFF in the lower part clearly visible. This view highlights the main bottom edge 1AF and the auxiliary bottom edge AXF, as well as the second main bottom edge 2AF, highlighting the gussets SFF and SFX, their folds PSFF and PSFX, and the three edges 1AF, AXF, and 2AF, showing the lenticular shape of the compartment bottom, delimited by edges 1AF and AXF, since the two ends of the gusset are integrated into the lower part of the two lateral edges 1AL of the first panel 1PA.

[0057] The view from below of the bag 100 in [Fig.4A] again shows the main edges 1AF, 2AF of the bottom, the auxiliary bellows SFX slightly open, delimited by the lens-shaped edges 1AF, AXF and the bottom bellows SFF slightly unfolded.

[0058] The top view of [Fig.4B] shows the opening of the bag and the LF closure line of the compartment between the first panel 1PA and the auxiliary panel PAX.

[0059] This view shows the upper edge IBS of the first panel 1PA, the upper edge BSX of the auxiliary panel PAX, the upper edge 2BS of the second panel 2PA and the lateral edge BLS formed by the two bellows SFL.
