Diiculties are often encountered in the transport of geometrically shaped articles or of pasty or solid goods, either because the materials have a regular shape which makes it impossible to t them conveniently inside a package or because the goods tend to adhere to the o sides of the packaging.

For these and other reasons, particularly the difficulty of extracting the transported material from its packaging, it was usual to transport such materials by means of rigid packaging such as woden packing cases or metal drums, the cost of which was high in relation to the material transported, and which, moreover, were genarally damaged during unloading or in transit and for this reason could not be re-used. Indeed, some materials could not be extracted from the packaging without destroying the latter.

The invention has as its object a method of constructing packagings, particularly flexible packagings made from cloth, canvas or the like, of vegetable or synthetic material, permitting a complete and immediate opening and reassembly without destroying any stitching or slitting any fabric, and also the'folding up of the packaging enabling its return under a small volume.

According to the invention, the packaging consists of different panels of which the edges to be assembled are provided with rigid or flexible rods, the adjacent rods of two panels being pressed together for closing by means of Amovable clips or simply brought together by any means.

One of the important advantages of the invention is that when it is applied to the manufacture of bags it permits the construction of bags the cross-section of which may be of any shape, polygonal or round, accordingto the shape of the articles to be inserted, so as to use the maximum available spacea construction which was' hitherto impossible or at least very difficult to achieve in an economic manner.

According to one application which seems particularly advantageous, the invention is used for the construction of packagings for carrying articles on motor cars, and particularly with a view to being associated with the luggage carriers mounted on the roofs of the cars.

The characteristics and advantages of the invention will become clear on reading the following description of various embodiments, given by way of example, with reference to the accompanying drawing, in which:

Figure l shows an ordinary bag according to the invention, consisting of a single element;

Figure 2 is a view, in cross-section, of two rods brought together and Y Y Figure 2a shows a section as in Figure 2 with an assembly clip disposedV securedV about the rods;

Figure 3 is a form of bag made by means of two crossed panels;

Figure 4 is a perspective view of the same bag with the panels assembled;

Figure 5 is a View of a pair of clip-pincers;

Figures 6 and 7 show another possible modiflcationfor making a package;

Fig. 7a is a sectional view taken approximately along the line 7a'-7a of Fig. 4;

Figures 8 and 9 show packagings according to the invention adapted for the transport of articles on motor cars, and

Figure l0 shows a pair of pincers for operating the clips.

A package according to the invention, for example a cloth bag, is made by using panels, of which the sides to be assembled are provided with rods.

Thus a bag as shown in Figure 1 is formed from a rectangular element l, folded along its minor axis to form two panels and of which the sides to be brought together,which would be sewn in the normal-method of making, are provided with

members

2, 3, 4, 5, inserted in hems 6 provided on the edges.

These members may consist of rods made of wood, metal, rubber or synthetic material and they may be solid or hollow, rigid or exible.

According to the invention, these rods are held together in pairs by clips 7, made of curved strips, preferably metal and having a suitable elasticity.

These clips are shaped so as to permit them to hold the joints together; they may end in loops 8, 9, which reinforce their rigidity at these points and permit them to be handled easily and to be pressed into locking engagement by means of a pair of mounting and dismounting pincers as shown in Fig. 5. As a matter of fact, the clip should have a strong joining power and it may not be possible to work them by hand. It will be an advantage to use a pair of pincers as shown in Figure 5. These pincers consist of two arms 1G, i1, pivoting about an axis 12 and ending at i3, 14 in hooks which are inserted in the closed loops of the clip. Simply by pressing and bringing the two arms together, the hooks will separate and undo the clips either for mounting or for removal; the length of the lever arms ofthe pincers depends on the effort to be applied.

Figure l shows one of the most simple shapes possible, which is that of the normal bag. It should, however, be understood that one of the advantages of the invention is to permit the making of packages, of cloth or exible material, having any geometric shape.

Thus, by means of two crossed

rectangular elements

15, 16 as shown in Figure 3, it is possible to form a bag in the form of a parallelopiped, as in Figure 4, the sides of which are assembled by means of rods and clips; the bottom i7, formed by two superimposed layers of cloth may also be reinforced, if desired, by providing rods 18 arranged along the line of superposition.

It would also be possible to form the bottom, either by starting with one panel, the sides of which are sewn to the corresponding sides of the panels forming the arms of the cross, or by sewing the strips one on top of the other as shown in Figure 3 where the parts are superimposed, or by using a detachable bottom comprising joints on the edges which would be xed by clips to four panels forming the sides. A detachable lid 19 can be made in the same manner.

Any geometrical shape is possible for the base according to the invention. Thus it is possible to make bags with a square, rectangular, trapezoid, triangular or round cross-section, which permits the bag to be lled to its maximum capacity with articles of various shapes which could not be tted exactly into a bag of the usual make. Similarly, the panels forming the sides may have any polygonal shape. Y

The bag, with detachable joints, could be made in the same manner by means of a lid of the same shape as the inserted in Vthe, edges of the clips.

vbottom, the cover being completely detachable or being rigidly secured to one of the side panels.

Alternatively, the bottom panels and the lid may beV formed in one as shown in Figures 6 and 7. In. general it is possible to'usel all'the shapesshown for making paper Yor card-board boX'es.In this case,1too, edges formed inside a panel-may be reinforced'.kwithjlfods:V ifY The invention Yhas beenirdeiscribed with reference ftoV the manufactureof bags of ilexible material; papier, any textile, or a sheet of synthetic'material or rubber, but

it should be understood that the invention could be usedV to make packaging` of rigid material such as Wood lor,

' hering to the sides, to permit the removal of the goods Without damaging the packaging since, in order to overcome the adhesion, it is then possible to apply a separate traction to each of the `panels forming the packaging which is a simple operation. y

It will likewise be understood that Yanother essential advantage of the invention is'to enable the various panels to be folded up upon each other so that the packaging, when emptied, can be returned under a small volume.

According to one rather special application of the invention, which seems most advantageous, a trunkis made of independent flexible panels as has been described, with a View to transporting articlesk in a motor vehicle Vand particularly on the roof of the vehicle. Its dimensions may beadapted, if necessary, ,to t the size of thelugg'age rack used; Y l *l y V Such a packaging or Ytrunk easilyV conforms to` the curve of the luggage rack or roof in both directons of the roof of the vehicle, longitudinal and transverse, and it can beV rolled up when not in use, thereby reducing the spacerthat it takes up and finally it can be used for other purposes Vif necessary.

A trunk of this kind is illustrated in Figure 8 on the accompanying drawing, whileV Figure 9 shows two such I Y 4 the lid may be secured to the trunk form a kind of hinge.k
