Definitions

  • Packaging in plastic containers such as plastic bottles, has the same disadvantages as that in glass bottles with regard to storage or stacking: the bottles must be housed in crates or rigid containers.
  • the permeability of thermoplastics to gases results in deterioration of the products during storage.
  • thermoplastic cubitainers do not have sufficient mechanical strength and must be packed in cardboard or plastic cases.
  • the products deteriorate either during storage or after partial racking which causes air substitution for the liquid volume, this latter drawback also being observed in all containers of relatively large capacity.
  • the object of the invention is to present a new type of packaging which eliminates these drawbacks, starting from the most advanced current techniques.
  • the container according to the invention is a double envelope container composed of a rigid box and a flexible internal pocket, characterized in that the box has the shape of a rectangular parallelepiped without internal partitioning, with entirely external ribs including ribs stacking, having a removable opening bottom in one piece, in the form of a rimmed cup fitting into the external box, the whole of the side walls of the box being provided with non-return hooking means of said bottom, said box being provided with a chimney, the wall of which projects partially outside the box, this external projection forming part of the annular ribs for stacking the box, and in that the flexible pocket is of volume greater than the internal volume of the body, consisting of a waterproof film extra flexible, of thickness less than 0.5 mm provided on its opening with a ring of external diameter close to the internal diameter of the chimney, provided with means for adapting a removable tap and carrying on its external face a flange cooperating with an internal flange of the chimney.
  • the internal pocket is produced by peripheral welding of two sheets or set of flat sheets of the extruded sheet type (and not blown), so that before filling it is absolutely flat and empty of air, and when filling it swells little by little until it occupies the entire volume of the box and then automatically collapses without air penetration during emptying. It is preferably produced by welding two sets of sheets, each set consisting of two sheets of the extra-thin polyethylene type (a few microns thick) between which is interposed a median film constituting an oxygen barrier.
  • the container according to the invention is then ready for transport; its rigidity allows its stacking as well as the protection of the internal pocket, and its shape ensures a useful volume of almost 80% of its size.
  • thermoplastics There is no risk of alteration of the products during storage due to the gas permeability of the thermoplastics, since the median film constituting the oxygen barrier is opposed to it, this which is not the case for cubitainer envelopes produced by blowing thermoplastics.
  • the container according to the invention is composed by the combination of two envelopes, namely an external envelope 1 constituting a rigid box in the shape of a rectangular parallelepiped having a removable bottom 11 forming an opening face, thus that a face 33 provided with a chimney 7; and an internal envelope 21 formed by a removable pocket with a volume greater than the internal volume of the box 1, consisting of a thin, waterproof plastic film of the order of 0.2 to 0.4 mm thick, of which l the opening carries a ring 22 hung in the chimney 7 and carrying a nipple-shaped drain plug 23 provided with a tap 24.
  • Box 1 is made of thermoplastic, molded by monobloc injection as well as the removable bottom 11,
  • the body 1 carries reinforcing ribs 24 on the lateral faces, and on the top it carries annular ribs 2, 3 which cooperate with the belt 6 for the straight or crossed embedding of containers during their stacking,
  • a retractable handle 4 is advantageously housed in these ribs.
  • One of the ribs 2 constitutes the lip or upper edge of the chimney 7.
  • Figures 2 to 5 show various variants for mounting the bottom 11.
  • the bottom has the shape of a bowl whose edges carry tabs, redents, or hooks 13 which cooperate with openings or lights 5 provided in the side walls of the box 1,
  • the bottom is locked which ensures the inviolability of the container.
  • the establishment and extraction of the bottom 11 are carried out as shown in dotted lines.
  • reliefs or recesses 26, 27 internal to the wall of the body 1 serve as support and locking for the bowl 11.
  • the role of support is provided by pins 28 fixed by clipping through the wall 1.
  • the advantage of the solution of Figures 1, 2 and 5 is that the hooks 13 oppose the deformation of the body 1 by swelling of the walls.
  • the hooks 13 are preferably surmounted or surrounded by a lip 12 extending the edges of the bowl 11 and obstructing the openings 5, so that the pocket 21 is protected and inaccessible from the outside.
  • such a film by means of several films of approximately 0.1 mm thick, laminated together, to give a multilayer film of the order of approximately 0.2 to 0.4 mm thick.
  • the pocket itself is made of two sheets of such a film welded together at their periphery,
  • the upper face 35 of the internal pocket 21, which carries the ring 22, is mounted on a relatively rigid chassis 37, made of plastic, the external dimensions of which are close to the internal dimensions of the face 33 of the body 1.
  • This arrangement has the effect that, once the pocket is in place, it deploys at the time of filling while retaining its upper face 35 suspended from the upper part of the box 1. As a result, it fills regularly while occupying the free volume of the box, filling which was not previously assured.
  • the chassis 37 advantageously includes lugs 38 which are fixed in attachment housings 39 provided in the wall of the body 1. Only three lugs 38 have been provided, at the corners of the chassis 37, the ring 22 constituting for its part a fourth point of attachment to the body 1.
  • the frame 37 is fixed to the face 35 by means of a plastic flange 41 of thickness of the order of 0.5 to 1 mm.
  • the chassis 37 to be sufficiently rigid must have a significant thickness, for example of the order of 3 mm and its fixing on the pocket would be difficult to achieve by welding, which on the contrary allows the use of a flange sufficiently thin.
  • the chassis 37 is shown as openwork in its central part, which is not essential.
  • the pocket 21 is produced by peripheral welding 34 of two flat sheets 21a, 21b, having the shape of a rectangle at knocked down corners (Figure 8). Each side of this rectangle is equal to one side of the upper face 35 of the pocket plus twice the half height of the pocket, the dimensions of the pocket being close to the dimensions of the useful internal volume of the case 1.
  • the angles are felled at approximately 45 ° to form cut sections 40 whose distance from the corners of the face 35 is approximately equal to the half-height d of the pocket.
  • the plug 23 provided with a tap is not put in place until the time of emptying, the pocket being temporarily closed, for storage and transported by a plug such as a lid screwed onto the ring. and the boucho; with tap coming to replace this cover at the time of use.
  • the invention preferably provides for the use of a plug 23 in the form of a flexible teat provided with a tap 24; thus after filling the final plug can be put in place, the valve 24 being retracted into the chimney 7 by pressing the teat during transport ( Figure 6) and extracted so that the valve 24 overflows out of the chimney 7 during employment.
  • the fixing of the plug 23 on the ring 22 is then produced after filling, by clipping onto a flange 28 carried by the ring.
  • an inviolable protective cap 9 is advantageously provided which covers the cap 24 and is clipped by the rods 8 in the washer 29 internal to the chimney 7. This protective cap can be used, in the case of wines, for affixing the holiday stamp.
  • the washer or flange 29 is also used, in the example shown for fixing the ring 22 in the chimney 7.
  • the ring 22 also carries a flange 30, of external diameter less than the internal diameter of the flange 29 and the ring 22 is forced in by elastic deformation, so that the flange 29 is located between the two flanges 30 and 31 of the ring 22.
  • the opening face 11 of the external rigid box 1 is that which carries the chimney 7 and to which the internal pocket 21 adapts.
  • the pocket 21 is adapted on the opening face 11, either directly or preferably by means of a chassis 37.
  • the fixing means 38 of this chassis 37 will preferably cooperate with housings 39 provided in the face 11.
  • the positioning of the pocket 21 in the body 1 is made by forcibly placing the legs 38 of the chassis 37 in the housings 39 and the plug 22 in the chimney 7 so that the flange 30, by elastic deformation, comes to protrude and is fixed on the flange 29,
  • the removable base 11 is placed after the pocket 21 has been put in place and the filling is carried out.
  • FIGS. 11 and 12 it is in face 11 that the pocket is put in place, and all of the face 11 and the pocket is put in place in the box 1 before filling.
  • the container shown may have an overall section of 200 mm x 300 mm and a height of approximately 340 mm for a stacked height of 320 mm (ie in stacking a volume of 19.2 1 for 15 useful liters hence a volume utilization coefficient of 78
