DEVICE FOR STORING AND PACKAGING MATERIALS The present invention relates to a device for storing and packaging materials, and more particularly to a holder for holding and closing removable flexible bags which can be used either for storing rubbish or household refuse, or for the packaging and presentation of merchandise such as foodstuffs.

In the present state of the art, devices of this type are generally complicated to construct and difficult to use.

The invention aims to overcome this disadvantage and its object is to produce a device of the abovementioned type which is simple to make and to handle and is suitable for hermetically sealing the removable bag.

According to the present invention there is provided a device for holding and closing a removable flexible bag, such device comprising a deformable band consisting of two equal length strips having a profiled cross section to form a spring, said strips being juxtaposed parallel to one another and located opposite one another with-their opposed faces each having at least one convex part, and connected to one another at each of their ends such that at rest the said strips are in contact with one another or very close to one another along at least one longitudinally extending zone, and means for mounting one of the strips in a central zone of its length to a supporting surface, whereby a flexible bag can be removably held by the deformable band with the neck of the bag being passed through the said band and folded back over the outer face of the band.

Thus, in this new device, it is possible to enclose materials, for example waste materials, after having placed these waste materials in the removable bag held by the device. This eliminates foul smells and prevents the spread of germs by parasitic insects, and furthermore means that the device may in some embodiments serve a frame holding the bag to enable the bag neck to be tied while the bag is gripped between the two strips at rest.

Where the stored materials consist of foodstuffs, the air enclosed in the bag at the time of the closing movement of the band assists the heat insulation of the said foodstuffs relative to the atmosphere.

Removal of the bag may be carried out very simply without tying up, if desired, merely by separating the strips from one another and by gripping the folded-over part of the neck of the said bag.

In order that the present invention may be better un derstood, the following description is given of three embodiments of the invention, merely by way of example, with reference to the accompanying drawings in which:

FIG. 1 is a view in perspective of a first embodiment of the device according to the invention;

FIG. 2 is a plan view of the device of FIG. 1;

FIG. 3 is a view corresponding to an elevation and vertical cross-section along the line III-III of FIG. 2 but showing a second embodiment of the device; and

FIG. 4 is a partial view in perspective showing a third embodiment of the device.

FIGS. 1 to 4 represent various embodiments of a device for storing and packaging for example household or industrial rubbish or foodstuffs such as meat, sausages, citrus fruits and the like. This device has means for holding and hermetically sealing a removable flexible bag, for example, a plastics bag 1 of rectangular shape.

As can be seen in FIGS. 1 to 3, the means for holding and closing the removable bag consist of a deformable band 2.

The neck of the bag 1 is passed through the deformable band 2 and is folded back over the outer face of the latter (as shown in FIG. 3 which illustrates a modified embodiment of the device of FIGS. 1 and 2). The deformable band 2 is produced from two

strips

3 and 4 which have a general elongated rectangular shape with rounded angles. The

strips

3 and 4 are both of identical shape and have a cross-section along their entire length following a constant profile in the shape of an arc of a circle. Thus, despite their profile they form a spring by virtue of their low thickness and of the elastic property of the material of which they are made, which material can be a metal such as steel or an elastic plastics material.

In other words, it is possible to make the

strips

3 and 4 undergo flexural elastic deformation in the direction of their length as is represented by the broken lines 30 and 4a of FIG. 2. The

strips

3 and 4 are juxtaposed parallel to one another and are located opposite one another in such a way that their convex faces 3b and 412 face each other. In order to form the deformable band 2, the

strips

3 and 4 are connected to one another at each pair of adjacent ends in such a way that, at rest, the said

strips

3 and 4 are in contact with one another or very close to one another, along a generatrix and over their entire length.

For this purpose, the

strips

3 and 4 are attached to one another at their ends by means of deformable connecting U-clamps 5 which, in the example represented, are made of rubber. Each connecting U-clamp 5 forms a hinge between the ends of the

said strips

3 and 4 and covers the outside of the latter in a median zone of their corresponding end edge (see FIG. 1). Each arm 5a of a connecting U-clamp 5 is firmly fixed, for example by gluing, to the

corresponding strip

3 or 4.

The centre part 5b of each connecting U-clamp 5, which forms the hinge axis, extends transversely relative to the

strips

3 and 4, is situated very close to the adjacent end of the said

strips

3 and 4, and is practically inextensible. Because of this characteristic, the perimeter of the deformable band 2 remains substantially constant when the

strips

3 and 4 are moved apart from one another into an unstable position such as that represented by broken lines at 3a and 4a, in FIG. 2. Thus, no additional stress is applied to the neck of the bag 1 during opening of the said bag 1 by separating movement of the

strips

3 and 4 into a position such as 3a and 4a.

Advantageously, the convex or outer face 5c of each U-clamp 5 is rounded so that the flexible bag 1 can rest against the said outer face 50 without running the risk of being torn.

One of the strips, the so-called back strip, 3, is attached by means of rivets at 6 in a median zone of its length to a supporting component. In the present case this supporting component consists of a plane vertical surface such as a wall 7. The back strip 3 is attached to the wall 7 via a sheet or plate 8 which is applied and attached, by its back face equipped with a self-adhesive layer 8a, to the said surface 7. A spacer component of parallelepipedonal shape 9 is interposed between the back strip 3 and the plate 8 and attachment rivets 6 pass right through it.

When the bag is filled with material the above described device can only hold the bag in a vertical position. In the example represented in FIG. 3, the bag 1 is not sufficiently deep for its base to rest on the floor and it is therefore in this embodiment necessary that each of the

strips

3 and 4 should be profiled over its entire length, so as to prevent the bag 1 from opening spontaneously due to the effect of forces exerted on the ends of the pair of

strips

3 and 4, these forces resulting from the weight of the bag 1 itself.

The

strips

3 and 4 are attached to the supporting surface 7 in such a way that the longitudinal axis of each

strip

3 and 4 is substantially horizontal and that the chordal plane of each profiled strip is substantially vertical.

Advantageously, the perimeter of the deformable band 2 is slightly greater than that of the neck of the bag 1 and, as can be seen in FIGS. 1 and 3, the foldedover part la of the said neck of the bag 1 has a greater width than that of the

strips

3 and 4 so that the free edge of the said folded-over part 1a can be stretched over the band outer perimeter and can press against the wall of the bag 1 to make the suspension of the said bag 1 on the band 2 very secure.

The strip 4 opposite the back strip 3, the so-called front strip 4, is connected to an opening member in the form of a handle 11 (FIG. 1) formed as a square ring 1] attached to the said front strip 4 in a median Zone of the length of the latter. In FIG. 3, the opening member is a ring which is connected to a pedal member, will be described below.

The pedal member of FIG. 3, consists of a lever 12 hinged at its end nearest the surface 7 to a fixed horizontal axis 13. The level 12 is connected at a point 12a a certain distance from the hinge axis 13, to a pull rod whose upper end engages the square ring 14 attached to the front strip 4. The lever 12 thus defines a pedal portion 15 at its end opposite the hinge axis 13. The upper end of the transmission rod 16 is in the shape of a hood 160 which is inserted in the said connecting ring 14.

FIG. 4 shows a variant of the pedal member of FIG. 3 and in this embodiment the lever consists of a rigid U-bar 17, whose centre part 170 forms the pedal portion of the said lever and whose arms 17b are attached at their free ends to one and the same horizontal rod 18 which pivots in fixed bearings 19 and forms the hinge axis. The pull rod in this embodiment consists of two rigid rods 20, each of which is attached at its lower end at 170 to a respective arm 17]) of the U-bar at the same distance a from the hinge axis 18 in each case. At its upper end each rod 20 is connected to a corresponding end of a rigid rod 21 which forms a connecting component and extends parallel to and alongside the front strip 4 and is attached to the latter in a median zone of its length by way of spacer components 22.
