Definitions

  • the present invention relates to a device for opening and / or closing a sealed package, in particular for preserving agri-food products.
  • hermetic packaging intended for the preservation of agri-food products
  • it may also be used for the packaging of any other type of product.
  • the opening / closing device comprises means for piercing the wall of said package and sealing means through which the packaging is pierced. Said closure means are able to close after piercing when the piercing means are removed so as to prevent any contact between the inner environment of the package and the surrounding environment.
  • this device also has certain disadvantages, in particular with regard to the sampling of the liquid and the risk of perforation of the packaging.
  • this device is used in a completely different technical field and has a structure too elaborate, and not adapted, which is not transposable to the field of the present invention.
  • the object of the present invention which is an improvement of the invention described in the document EP-1312556 is to propose a device for opening / closing a hermetic packaging, in particular intended for the preservation of food products, which overcomes the aforementioned drawbacks and makes it possible to take or inject liquids, semi-liquids or gases, such as nitrogen and / or steam, out of or in the package, without any contact between the indoor environment and the environment.
  • Another object of the present invention is to provide a device for opening and closing a hermetic packaging, in particular for preserving agri-food products, which makes it possible to obtain data on the inner environment of the packaging by preventing any contact between the internal environment and the external environment.
  • Another object of the present invention is to provide a reliable opening / closing device and whose implementation is easy, especially avoiding the risk of inadvertent perforation.
  • the device for opening / closing a hermetic packaging in particular intended for the preservation of food products, having piercing means, as well as closure means through which the piercing of the food is carried out.
  • packaging and being able to close after piercing when the piercing means are removed so as to prevent any contact between the inner environment of the package and the environment, said closure means being constituted by two cage-shaped elements , arranged at the wall of said package, and secured together, the first element provided on the ambient medium, being lined with a thermoplastic material adapted to close after piercing, is characterized in that the second element is provided on the inner side packaging, and constitutes, on the one hand, a stop for said piercing means, as well as, on the other hand, spacer means of the opposite wall of the package to create an incompressible volume depression chamber at the level of the piercing means.
  • the present invention also relates to a package equipped with the sealing means described in the present invention.
  • the invention relates first of all to an opening / closing device 12 for a hermetic package 10, especially intended for the preservation of agri-food products.
  • this device also applies to hermetic packaging for any other product and for example the storage of pharmaceutical or chemical products.
  • the opening / closing device 12 of a hermetic package 10 comprises piercing means 8 of the wall 3 of said package 10.
  • the opening / closing device 12 also comprises closure means 13 at the through which the packaging 10 is pierced, and which are able to close after piercing when the piercing means 8 are removed so as to prevent any contact between the inner environment of the package 10 and the ambient environment.
  • said closure means 13 consist of two elements 1, 2, each in the form of a cage, in particular cylindrical, arranged at the wall 3 of said package 10, and secured together.
  • the first element 1, as developed below, is lined with a thermoplastic material able to close after piercing.
  • the second element 2 has spacer means for creating a vacuum chamber at the level of the piercing means.
  • said two functional elements can consist substantially of two independent parts, secured together during their molding, at the level of the package to be equipped, or constituted of a single piece piece.
  • the attachment can also be made on the inside or outside of the wall 3 of the package.
  • the element 2 is previously clipped onto the element 1 before the assembly is welded to the package 10.
  • said vacuum member 2 or strainer has a cylindrical body equipped with a closed bottom 15 and at least one hole 11 on its side wall. This has the advantage, on the one hand, to form a dam to prevent solid pieces block the piercing means 8, while allowing the liquid to flow freely, and on the other hand, to avoid the piercing desired two sheets of the package.
  • said closure means 13 may consist of a single piece 28, monobloc type, which can be fixed on the inner face 29 or outer 30 of the wall 3 of the package 10.
  • the functions described about the means shutter 13 made in two independent parts remain similar.
  • One of the advantages of using this type of closure means 13 in the form of a single piece 28 is to allow the welding, in particular, between the piece 28 and the wall 3 of the package 10 at one time .
  • the welding can be carried out either between the surface 32 of the base 33 and the surface 30 of the wall 3 of the package 10, as shown in FIG. figure 9 or between the surface 31 of the base 33 and the surface 29 of the wall 3 of the package 10, as shown in FIG. figure 10 .
  • the base 33 can be placed either inside or outside of the package.
  • said closure means 13 further comprise at least one thermoplastic material advantageously of elastomer type, in particular provided for in FIG. level of said element 1 said shutter.
  • thermoplastic material must have specific characteristics allowing when said shutter means 13 are drilled, to close the holes created.
  • said at least one material used must have a high coefficient of elasticity and also an average hardness so that said sealing means 13 have a good hold and that the hole closes instantly, that is to say that is, at no time does the environment come into contact with the inner environment of the package 10.
  • thermoplastic material consisting of a material sold under the trademark "VITAPRENNE” will advantageously be chosen, said material having a shore hardness close to 41 and elongation coefficient close to 50%, the wall of the sealed package 10 being made of a polyethylene film associated with the polyamide, the latter being used as a gas barrier film.
  • the closure element 1 in the form of a cage, successively has a first outer base 4, a hollow zone 6, delimited by a wall 5, in order to accommodate a disc 7, and an opening 21.
  • decompression element 2 in the form of a hollow cage, successively has a second base 4 ', said bottom 15 and at least one of said holes 11 on its side wall.
  • Element 1 may furthermore have four anchor points in its periphery (not shown). These anchoring points allow the needle 25 to be held in abutment in the bottom of the element 2 for the duration of the intervention in the package 10 and secondly to ensure that the hole 9 of the needle 25 will always be in the axis of the holes 11. This anchoring system also makes it possible not to exert stress on the package 10 at the time of the perforation of the sealing means 7.
  • the hollow zone 6 is limited in its lower part by an internal annular shoulder 27 in order to limit the deformation of the disc 7 during its perforation by the needle 25.
  • the perforation is performed by the hole 26, whose diameter may vary between and 10 mm, advantageously 8 mm.
  • said shutter member 1 is able to contain said disc 7, as illustrated in FIGS. Figures 2 to 5 , said thermoplastic material and the front opening 21 is adapted to allow on the one hand the introduction of said disk 7, and secondly its crimped retention in said element 1.
  • the disk 7 is circumscribed by said wall 5, so that said wall 5 constitutes a strapping or crimping of the disk 7.
  • the element 2 is able to constitute a stop for the piercing means and an incompressible internal volume.
  • This element 2 thus constitutes a strainer or a suction filter to avoid, for example, that the wall of the package does not come to press against the suction port of the needle and does not suction circuit.
  • each base 4, 4' is intended to cooperate with the wall 3 of the package 10.
  • each base 4, 4' will have an annular groove 23 and a shoulder 22 corresponding to the one hand the location of two elements 1, 2 and on the other hand facilitate their positioning.
  • the dimensions of the sealing means 13 are determined firstly to be sufficient to allow easy positioning of the piercing means 8 and secondly relatively small so as to require a minimum of material whose cost is high.
  • said piercing means 8 consist of a needle 25 having an orifice 9 at the portion piercing the wall 3 of said package 10.
  • the shape of said needle 25 allows in particular the insertion of said injection means and / or suction, injection and / or aspiration of liquids, semi-liquids and gases, such as nitrogen and / or steam being through said orifice 9.
  • said orifice 9 allows contact between the inner medium of the package 10 and the interior of said needle 25.
  • said needle 25 has only one opening constituted by said orifice 9.
  • This orifice 9 prevents any contact between the inner medium of the package 10 and the ambient medium has dimensions determined so that, during perforation, the orifice can not bring into contact the inner environment of the package 10 and the ambient environment.
  • the dimension of said orifice 9 along the axis of perforation is less than the total width of said closure means 13 and the wall 3 of said package 10.
  • an orifice 9 having opening / closing means, the orifice 9 then being plugged when the orifice is on the outside of the package, and open when the orifice is inside the package.
  • the present invention also relates to a package 10 equipped with closure means 13 as mentioned above.
  • the present invention furthermore relates to an installation for the implementation of such packages, in which provision is made, at the level of said piercing means 8, for injection and / or suction means allowing the injection and / or the aspirating liquids, semi-liquids and gases, such as nitrogen and / or steam, in and / or out of the package preventing contact between the inner environment of the package 10 and the surrounding environment.
  • the invention can also provide, at the level of said piercing means, a sensor enabling data to be obtained on the inner environment of the package 10.
  • the operation of the opening / closing device 12 is as follows.
  • a first step, represented in figure 2 said piercing means 8 formed in the example by the hollow needle 25 are preferably positioned vertically of said closure means 13.
  • piercing of said closure means 13 and the wall 3 of the package 10 is carried out.
  • the wall 3 is broken, and it can also be seen that the said closure means 13 consist of said elements 1 and 2 are pierced.
  • the rim 7a of the disk 7 bears against the edges of said needle 25 thus preventing any contact between the inner environment of the package 10 and the environment.
  • the orifice 9 of said needle 25 is in contact with the inner medium of the package 10 through the holes 11 of the element 2, it is therefore possible to suck or inject liquids, semi-liquids and and / or gases, such as nitrogen or steam, from the injection and / or suction means 19. It is also possible at this stage by means of said sensor 17 to obtain data on the inner environment of the package 10 and in particular temperature measurements.
  • the needle a diameter representing approximately one quarter or even one quarter to one sixth of the diameter of the washer.
  • the needle 25 has a diameter of 5 mm and defines an internal conduit 3 mm in diameter
  • the washer has a diameter of 20 mm and a thickness of 8 mm.
  • the injection and / or suction means 19 allow the suction of a liter of liquid in 45 seconds. The suction speed depends of course on the viscosity of the liquid to be injected or aspirated.
  • the needle 25 has a diameter of 4 mm, and defines an internal conduit of 2 mm in diameter, and the washer has a diameter of 20 mm and a thickness of 8 mm.
  • the injection and / or suction means 19 allowing suction of one liter of water in one minute.
  • the choice of the dimensions of the needle 25 and the closure means 13 will be determined in a general manner, on the one hand, by the time available for the injection and / or suction operations and, on the other hand, by the amounts of liquids and semi-liquids to be injected or aspirated.
  • This device therefore makes it possible, particularly in the case where it is intended for the preservation of agri-food products, not to have to unpack the products and then to repackage them and thus to use only one packaging, which provides this device with a significant ecological and economic advantage over known devices.
