Description

DESCRIPTION attached to the patent application for industrial invention entitled? THERMOFORMED CONTAINER FROM FOLDED TAPE OF THERMOELABORABLE MATERIAL, COMPLETE WITH DISPENSING OR CONNECTION DEVICE?

FIELD OF TECHNIQUE

The invention relates to the construction technique of containers of fluid substances obtained by thermoforming from a folded strip of heat-processing materials.

STATE OF THE TECHNIQUE

Different types of containers are known obtained by heat-sealing strips of heat-processing materials, in particular the following patents are known: BO 94 A0Q0482, DEPS 1081335, DEAS 1189258, DEOS 3141069, CH 361662, CH 416445, CH 437102, BE 556274, FR 1134426 , FR 1199371, FR 1203209, FR 1265926, FR 1453508, FR 2201958, FR 2667843, WO 95/25665, EP 0169183, EP 0378027, EP 0479152, EP 0612664, EP 0662910, EP 0692364, EP 0692428, EP 071511708, US 299008 , US 3039246, US 3040380, US 3099043, US 3142089, US 3327035, US 3380608, US 3423902, US 3505705, US 4004397.

Do not all known containers solve the problem of? Reliable application of connecting or sealing devices, dispensing and sealing. In fact, in all the known types, the fixing of the aforementioned devices is not? performed with contrast crews external to the container. The problem to be solved? that of being able to dispose, on the container, of a flat area, shaped in such a way as to allow the intervention of contrast crews from the outside during the execution of the heat-sealing operations of the attachment flange of said devices.

DESCRIPTION

The present invention is now described in detail with reference to the figures of the attached drawings by way of non-limiting example.

The figure schematically represents the upper edges of the belt folded orthogonally one on one side and one on the other in the sealing plane of the container. Figure 2 schematically illustrates the heat sealing operation of a dispensing device whose attachment flange? positioned in correspondence with the filling channel of the container.

Figure 3 shows a plan view of the coplanar area for the attachment of the flange of the dispensing device.

Figure 4 represents the vertical section of the welding operation of a connection device.

Figure 5 shows the attachment of the connector device in a median front section. Figure 6 shows a plan view of the coplanar area for the attachment of the flange of a connection device.

In the figures, every single detail? cos? marked:

1 and 2 are the edges of the tape of heat-sealable material;

3? the tape of heat-sealable material;

4? the container heat-sealing surface;

5? the thermoformed container;

6 are the filling channels obtained during thermoforming in correspondence with the sealing plane of the container;

7 indicates a sealed opening, dispensing and reclosing device applied in correspondence with said filling channels;

8 indicates a connection device applied in correspondence with said filling channels;

9 indicates the attachment flange which must be heat-sealed on the folded edges of the container;

10 indicates the equipment that, from the outside of the container, counteract the thermo welding operations of said flange;

1 1 the heat sealing crew;

12 indicates the plane in which the condition of coplanarity occurs? of the two edges folded orthogonally;

13 indicates the flat bottom of the container;

14 indicates the appendix protruding from the bottom of the container;

15 indicates the hooking hole of the overturned container.

From the illustrations it is evident that the fastening of the connection or dispensing devices takes place in correspondence with the filling channels which are made during the thermoforming operations of the container from the folded belt. It can be seen, in figure 2, that the container can? show up with a flat bottom, or, as you can see in figure 3, can? be made with extremities? bottom with protruding fin with hooking hole to hang the container upside down. Of course the invention? susceptible of various variants of practical embodiment, as regards the structural proportioning and the various external shapes of the container. AND? It is clear that the inventive content consists in the fact that the two edges of the strip are folded orthogonally, one on one side and one on the other. other of the two sealing surfaces of the container. Therefore, all those containers obtained by heat-sealing from folded tapes of heat-sealable material which have coplanarity will fall within the basic principle of the present invention. of the edges turned orthogonally in correspondence of the filling channels to allow you to fix the attachment flange of dispensing or connection devices by means of contrast heat-sealing operations with crews acting on the exterior of the container, with the characteristics substantially described, illustrated and claimed hereinafter.

Claims (1)

CLAIM Thermoformed container from folded tape of thermo-processing material, complete with dispensing or connection devices, CHARACTERIZED BY THE FACT that the upper edges 1 and 2 of the tape 3, folded orthogonally one on one side and one on the other of the d? welding 4 of the container 5, are coplanar 12 and allow to fix on the container, in correspondence with the filling channels 6, crossing said welding plane 4, with dispensing or connection devices 8, fixed to said coplanar flaps (1,2, 12) by means of heat-sealing operations 11 of the relative attachment flange 9 opposed by equipment 10 external to the container 5.
