FR2587304A1 - Anti-shock case for the transportation of fragile objects and for their display - Google Patents

Abstract

The subject of the invention relates to an anti-shock case for the transportation of fragile objects and for their display. It is constituted by the combination of an outer envelope 1, 2 made of strong but flexible material comprising on its internal walls a lining which is shock-absorbing and isothermal because of closed air cells 4, 5, with a closing flap 3, 3' also comprising a shock-absorbing and isothermal lining with spaced and closed air cells. It is more particularly intended for the dispatch and return of several models of dental impressions and of dentures between laboratories and practitioners but may also be used for electronic and computer parts or the like.

Description

 The object of the invention relates to an anti-shock case for the transport of fragile objects and their presentation.

 It is more particularly intended for the to-and-fro of several models of dental impressions and prostheses between laboratories and practitioners but also be used for electronic, computer or similar parts.

 It is known to use envelopes or paper cases and shock-absorbing shock-absorbing linings, but in the event of friction, pressure or the like, the product transported could deform or break.

 The device according to the invention eliminates these drawbacks and makes it possible, by the new application of closed-cell shock-absorbing air bubble film covering the internal wall of the resistant external envelope which with folding doubling the shock-absorbing walls on one side achieves a triple protective screen allowing to obtain a double effect, first the stabilization of the transported objects and then their protection against shocks or thermal effects with the sealing shutter; this case is made of a very flexible covering so that it can be inserted and get stuck or even roll up in a rigid box for shipping; it also ensures in the case of dental prosthesis the retention of a certain necessary humidity; it is also planned to obtain decorative presentation effects.

 I1 is constituted by the combination of an external envelope of resistant but flexible material comprising on its internal walls a damping and isothermal lining by air cells with closed honeycombs with a closing flap also comprising a damping and isothermal lining with cells air spaced and closed.

In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention
Figure 1 shows in elevation and in longitudinal section the case and the deployed closing flap.

 Figures 2 and 3 show the folding modes with closing flap forming a shock absorbing wall.

 Figures 4 and 5 show alternative embodiments.

 Figure 6 is an elevational view of the front face of the case.

 The case is formed by an enveloping surface with sector 1, 2 forming a sealed capacity and a folding closing flap 3.

 A damping film constituted by a flexible surface with the closed cell bubbles 4, 5 completely covers the sectors 1, 2, 3.

 The sector 3 is formed by folding the strands 3, 3 ′ enclosing the axial film 6.

 On the external face 1 are provided two loops 7, 8.

 The objects 9, 10, 11 are introduced into the case 1, 2, and the flap 3 is placed, either inside, FIG. 2, or outside and immobilized by the passers-by 7, 8.

 In any event, the object is protected by a double lining and on one side by three thicknesses of anti-shock lining.

 We can even roll the flap 3, 3 'around a room and introduce it in the pocket to increase the protections.

 The case may include a pocket closed by the walls 11, 12 with impact-resistant insulating lining 13, 14 on the internal faces and free extension 15, that is to say not adherent to the wall. This flap 15 serves as a housing between 3 and 3 'or fold 18, for placing a work sheet or plan or other document relating to the object contained in the case. This same flap can also, folded, be introduced between the lining 5 and the wall 12 (FIG. 4) by removing the junction point 17. Finally, this flap 15 covered by an adhesive or the like can be applied to the external face 12 and make a closure.

Junction points 16, 17 immobilize the lining
The folding sector 18 does not have a lining, only the flap 15 provides the closure 19, fig 4, 5.

 In any event, the case 20, fig 6, allows a tight closure by the flaps 3 or 18 and with folding of the insulating lining. This folding can be immobilized either by passers-by 7, 8, or by the use of an adhesive substance or still according to the applications by a welding or still be introduced in the case, fig 2 ..

 The transported objects are stabilized in their position by the slight pressure of the air bubbles and the carrier film.

This elastic pressure is distributed by the external envelope and this stabilizing effect avoiding any deformation of transported objects, the impact protective effect by the external and internal triple wall of the envelope of the case and its lining.

 It is possible to make an equivalent case from two pockets made in isolation, the protective pocket being smaller for its introduction into the lower part of the other. The junction points 16, 17 or others being established next.

 The folded pocket 18 serving as a closure and document holder could be added by bonding or other welding.

 The outer wall of the case as well as the trim can be transparent, which makes it possible to check the condition at the same time as the contents.

 Finally the shock absorbing lining is thermally insulating can be fixed to the envelope by bonding points, by welding points or adhere with a coating repainted over the entire internal surface of said envelope.

 The ease of insertion through the total upper opening facilitates access and positioning of the transported objects.

 However the forms, dimensions and arrangements of the various elements, as moreover the nature of the materials used may vary within the limit of equivalents as well as the volumes and spacing of the air bubbles without changing for this, the general design of the invention which has just been described.
