Definitions
- the present invention relates to a container having an opening provided with a hermetic closure element for packaging a product, the wall of this container being intended to be subjected to a pressure greater than its resistance, at least part of this wall being of a malleable material and being shaped with zones of different resistance to pressure, so as to generate, once subjected to said pressure, a controlled deformation of the parts of lower resistance.
- JP-32-58253 a cylindrical container comprising a tabular body, one end of which is hermetically closed by a cover, while the other end is closed by a flexible hermetic closure member capable of undergoing deformation. without the rest of the container deforming.
- the deformable part forms a single piece with the non-deformable part, for example, by thinning the deformable part, one is limited by the materials that can be used and this limitation is likely to harm the presentation of the product packaged in such packaging.
- the object of the present invention is to remedy, at least in part, the above-mentioned drawbacks.
- the subject of this invention is a container of the aforementioned type, characterized in that said closure element has a peripheral portion which extends beyond the edge of said opening and that this peripheral portion is made integral with both the edge of this opening and of the edge of the opening of an external container receiving the hermetically sealed container, the wall of this external container having at least one opening intended to bring the wall of the hermetically sealed container into contact with the medium surrounding the outer container.
- the outer container protects the more fragile inner container, insofar as it can be made of a more rigid material. It also allows you to modify the information it can receive without modifying the inner container. This allows a different presentation on different markets, by simply changing the outer container, the inner container always remaining the same. This simplifies the production tool.
- Figure 1 is a sectional elevation view of a first embodiment.
- Figure 2 is an elevational view of Figure 1 during the processing of the packaged commodity.
- Figure 3 is a side elevational view of a second embodiment.
- Figure 4 is a sectional elevational view of a third embodiment.
- Figure 5 is a sectional elevation view of a fourth embodiment.
- the embodiment illustrated in Figures 1 and 2 comprises two containers, an inner container 1 provided with a flange 2 and an outer container 3 provided with a staircase flange 4, the internal part of this flange 4 serving to receive the collar 2 of the inner container 1.
- the two containers 1 and 3 are closed, for example, by the same cover 5, fixed to the respective collars 2 and 4 by simultaneous heat-welding of two concentric zones, with a suitable electrode profile 9.
- This cover 5 can be replaced by a rigid cover hermetically fixed to the two containers.
- the bottom 6 of the outer container 3 is perforated with at least one opening 7 to allow the passage of the treatment liquid under high pressure.
- the commodity 8 contained in the inner container 1 for example occupies about 90% of the volume of this container at ambient pressure, during tests carried out.
- one of the principles used for the production of the internal flexible container on which the packaging container object of the invention is based is the following: the internal container 1 has a wall thermoformed by suction in a mold. By very quickly triggering the suction phase of the material heated to the shaping temperature, a container is obtained whose wall has a thickness gradient going from the flange to the bottom of the container, the thinnest part being in the center of the bottom.
- this thickness gradient which can range, for example, from 0.65 mm towards the collar 2 to 0.2 mm in the center of the bottom
- the pressure isostatic exerted by the process water slightly deforms the thinner part of the wall of the inner container 1, that is to say the cover 5 but above all, due to the low extensibility of this cover, the bottom for compress the volume of gas as well as the inlet 8 contained in this container 1 which takes a shape similar to that illustrated in FIG. 2.
- the container After the treatment, when the container regains atmospheric pressure, it returns to its initial shape provided that the lid 5 closes the container tightly. Indeed, in this case, the air and the food find their initial volume and the container because of the malleability of the tooth material it is made, having undergone a controlled deformation, finds its initial firm.
- the inner container 1 was produced under the following conditions:
- a 0.9 mm thick PS container was thermo-formed with an average diameter of 63 mm and a height of 79 mm using an imprint connected to a suction source and a punch .
- the speed of descent of the punch into the cavity is 240 mm / s with stopping at 5 mm from the bottom of the cavity by triggering the suction 0.5 s after the start of the descent, the total stroke of the punch being 385 mm.
- the internal container 1 representing an easily deformable part, the presence of the external container 3 serves as a comparatively rigid element allowing handling, stacking, transport under the conditions of normal packaging.
- FIG. 3 illustrates another embodiment comprising an inner container 11, relatively rigid, provided with a flange 12, an outer container 13 provided with a flange 14.
- the flanges of these two containers are connected to each other. 'other by a flexible sleeve 19 whose two ends are welded respectively and successively to the flanges 12 and 14.
- the end of the flexible sleeve 19 fixed to the flange 14 is further secured to the latter and with a lid or a closure cover sealed 15 of the inner container 11.
- the sealing system 15 can be made in two stages, or simultaneously. as in the case of FIG. 1.
- a first flat thermoscel lage is produced between the sleeve 19 and the inner container 12, with a suitable see binding ring.
- the bottom 16 of the outer container 13 is pierced, here for example, with a central opening 17 for the passage of the pressurizing liquid.
- the commodity 18 fills for example about 90% of the volume of the internal container in the case of the tests carried out. During the pressure treatment of this commodity 13, it is therefore the flexible sleeve 19 which deforms to allow the reduction in volume of the inner enclosure 11 to be absorbed.
- the containers 11 and 13 can be made of a multilayer complex PS / EVOH / PE 0.75 mm thick, the PE being inside and the flexible sleeve 13 is made of a laminate of FE / PA / PE 0.3 mm thick.
- the cover is made of Al coated with PE.
- This type of packaging makes it possible, by removing the cover 15, which can be made peelable with suitable materials, to release the assembly of external container 13, sleeve 19 and internal container 11.
- FIG. 4 illustrates another variant of FIG. 3 in which the flexible sleeve is here constituted by a thermo-formed sleeve in a flexible material in the form of steps 21 allowing progressive deformation and the internal edge of which is welded to the flange 12 of the inner container 11 and the outer edge is welded to the collar 14 of the outer container 13.
- the thermoscel 1 age of the sleeve 21 is made, for example, in two successive steps.
- a first seal is formed between the sleeve 21 and the flange 12.
- the second seal concerns the simultaneous welds of the outer part of the sleeve 21, of the flange 14 and of the cover 15, as in the case of the embodiment illustrated in Figure 1.
- This embodiment allows the demolding of a gelled commodity.
- the embodiment illustrated in FIG. 5 does not differ from the previous figure, in that the flexible sleeve 19 is replaced here by a bellows 20 formed by two rings 20a, 20b cut from a PE / PA / PE film by example welded together along their internal edges. The outer edges of these two rings 20a, 20b are welded respectively to the collar u of the outer container 13 and to that 12 of the inner container 11. The heat sealing is done as in the previous case in two stages. An insulating material is positioned between the rings 20a and 20b to allow the flat sealing of the ring 20a with the ring 12 at first. The sealing of the outer flange 14 with the ring 20b and the cover 15 takes place as in the case of the embodiment illustrated in FIG. 1.
- This embodiment of FIG. 5 does not allow the release of the foodstuff which is conditioned therein when it is solid, so that this form of packaging lends itself essentially to a liquid foodstuff capable of being consumed with a straw, for example.
- the invention which is the subject of the present invention can be used in particular in the case of the treatment of products under high pressure. However, it is in no way limited to such an application and applies to all cases where the product packaged in a hermetically sealed container is liable to change volume after this closure. This allows in particular the hot filling, or the hot sterilization of the product after its packaging.
