  • the package is parallelepipedic, in a flexible material and its opening is closed by four flaps.
  • the invention also relates to the use of such a packaging for storing food under relative vacuum.
  • the closure device 1 comprises three superimposed plates 2, 3, 4.
  • the lower plate 2 comprises an area with at least one through hole 5 of 0.5 to 15 mm in diameter.

  • the intermediate plate 3 also comprises an area provided with through holes 5 positioned to be superimposed with the holes 5 of the lower plate 2 when the two plates are fixed to one another as will be described later.
  • This intermediate plate 3 normally comprises lateral longitudinal rails 8 and a transverse flange 9, so as to allow a sliding connection of the upper plate 4, which can be inserted into the slides 8 by the last side 10 of the intermediate plate 3 and slide in the slideways 8 to abut against the opposite flange 9.

  • the figure 2 illustrates the three superimposed plates in an open position, in which the opening 11 is superimposed on the through-hole zones 5 of the two plates 2, 3.
  • the device can easily be placed in the closed position by sliding the upper plate 4 to the left up to abut against the flange 9.
  • the through holes 5 will be covered by the solid zone 12 of the upper sliding plate 4 which thus closes these openings and seals the system.
  • the third plate 4 could also, according to another embodiment not shown in the figures, be mounted on the intermediate plate 3 by means of an axis of rotation allowing it to perform a rotary movement to reach its two positions.
  • the upper plate 4 preferably does not have a large diameter circular through opening 11 as mentioned above, but has at least one opening of smaller diameter, preferably of the same diameter as through the through holes 5.
  • the axis of rotation can thus be arranged symmetrically between the holes 5. It is also possible to provide in this case a coloration of certain parts of the upper surface of the intermediate plate 3 so that these parts are visible through the openings of smaller diameter in the upper plate 4 as soon as it is in the closed position. All these measures are obviously also conceivable for the first embodiment with linear displacement of the upper plate 4.
  • the third plate 4 could also have, in the aforementioned embodiments, a connection means in the form of a tip protruding from its upper surface surrounding the opening 11 respectively the set of smaller openings diameter and adapted by its diameter to receive said tip of a standardized vacuum cleaner.
  • this protruding tip can serve as a lever to perform the movement of the third plate 4, whether it is a linear or rotary movement.
  • a groove in the upper plate 4 surrounding the opening 11 respectively smaller diameter openings and adapted to receive said nozzle of a standardized vacuum cleaner may be provided.
  • an adaptation means in the form of a gearbox adapter for mounting on a standardized vacuum cleaner or any other means intended to create a vacuum. This gearbox adapter is arranged so that it can be mounted at one of its ends on the vacuum cleaner and at the other on the opening or openings of the upper plate 4.
  • the through holes 5 of the lower plate 2 and / or of the intermediate plate 3 may be equipped with a filter having holes of smaller diameter, preferably ranging from 0.1 to 1 mm. This filter is useful depending on the product to be put in the bag or packaging.
  • the figure 3a illustrates in greater detail the arrangement of the three plates 2, 3, 4 of an embodiment of a closure device according to the present invention schematically showing an explosion view partly in longitudinal section along the line II to the figure 2 .
  • the device is at the figure 3a in the position just before assembly and corresponding to its closed position.
  • the second plate 3 comprises at least one tube 6 fixed substantially perpendicular to its surface facing said first plate 2.
  • the tube 6 houses a channel in communication with said at least one opening 5 of the second plate 3, the channel having a diameter chosen according to the diameter of the through hole 5, preferably about 2 to 10 mm.
  • the tube 6 has a length capable of at least partially passing through said at least one opening 5 of the first plate 2 when the second plate 3 is positioned on the first plate 2. It should be noted here that said at least one tube 6 could alternatively or simultaneously, be also disposed on the surface of the first plate 2 facing said second plate 3, with a length adapted to at least partially pass through said at least one opening 5 of the second plate 3.

  • the at least one tube 6 of the second - 3 respectively of the first plate 2 has an outside diameter C corresponding to the diameter A of said at least one opening 5 of the first - 2 respectively of the second plate 3, so that said at least one tube 6 of the second - 3 respectively the first plate 2 is adapted to cooperate with the first - 2 respectively the second plate 3 to fix the two plates 2, 3 together.
  • the closure device does not need separate fastening means such as pins or fixing pins on a board and fastening openings with a complementary geometry on the other board, this would require additional through holes in the package or the bag.
  • the present invention then makes it possible to ensure a mechanical fastening between the first-2 and the second plate 3 using only said at least one tube 6.
  • This tube simultaneously houses the channel allowing, in the open position of the device, a circulation of gas through the device.
  • the figure 3a also shows that said at least one tube 6 of the second plate 3, respectively of the first plate 2 in the inverse constellation, may be a separately manufactured part having a diameter fixing head exceeding the outside diameter of its part comprising the majority of the channel.
  • This type of tube 6 is incorporated in the second - 3 respectively the first plate 2 by placing the fixing head in a housing of the plate 3, 2 and then covering it with a fixing plate having at least one opening superimposed on said at least one opening 5 of the plate 2, 3.
  • Any other suitable means can be used for this purpose, as long as it ensures that the fixing head of each tube 6 is fixed in the mass of the plate 2 , 3.
  • said at least one tube 6 of the second - 3 respectively of the first plate 2 can be manufactured in one piece with said plate 3, 2.
  • the Figures 3a and 3b also show, by way of example, that the layer 7 of flexible material of the first - 2 and / or second plate 3, depending if said at least one tube 6 is disposed in the second - 3 and / or in the first plate 2, is fixed inside the plate 2, 3 or on its surface facing the second - 3 respectively the first plate 2.
  • this layer 7 of flexible material of the first - 2 and / or the second plate 3 is fixed in the plate 2, 3 so as to be easily replaceable, which is advantageous because the closure device according to the present invention is reusable and can therefore be damaged in certain parts in case of dismantling and repeated reassembly.
  • the layer 7 of flexible material of the first - 2 and / or the second plate 3 is advantageously made of elastomer, silicone or rubber.
  • the figure 3c shows schematically and by way of example a form of execution corresponding to the figure 3b , but in which the arrangement of said at least one tube 6 and the layer 7 of flexible material is reversed with respect to the embodiment illustrated in FIG. figure 3b .
  • the plate 2, 3 comprising the layer 7 of flexible material may also include a portion of greater thickness to receive said elastomeric layer or other suitable material.
  • the through openings 5 of the board 2, 3 receiving said at least one tube 6 are advantageously arranged so as to have, at the end opposite the end receiving the tube 6, a portion of smaller diameter corresponding to the inner diameter of said tube 6, that is to say corresponding to the diameter of the channel in the tube.
  • the Figures 3a, 3b and 3c also show that the third plate 4 has, on its surface facing the second plate 3 and covering its superimposed zone in the second position of the third plate 4 to said at least one through opening 5 of the other two plates 2, 3, a layer 4.1 of flexible material.
  • This layer 4.1 of flexible material of the third plate 4 is preferably housed freely in a housing 4.2 provided in the third plate 4 at its surface facing the second plate 3.
  • This arrangement of the layer 4.1 allows, once the packaging is under relative vacuum and the third board 4 is in the closed position, that is to say that the inside of the packaging is under pressure and that the layer 4.1 is superimposed on the through openings 5 first and second planks 2, 3, that the underpressure causes the adhesion of this layer 4.1 against the inlet of said at least one opening 5, thus reinforcing the tightness of the closure device 1.
  • This effect can still be reinforces by making said layer 4.1 of the third plate 4 of a flexible material such as elastomer, silicone or rubber. These materials allow at the same time an easy sliding of the third board 4 in the slides and on the surface of the second board 3.
  • FIGS. 4a, 4b and 4c illustrate a possible use of the closure device on a package, for example a bag 20 flexible and very simple rectangular parallelepiped shape, provided with an upper opening 21 can be closed by four flexible flaps, two large flaps 22, 23 placed on the large side of the bag and two small flaps 24, 25 placed on the short side of the bag.

  • the lower plate 2 of the closure device is placed under the two flaps 22, 23, in a central zone of the opening 21 not covered by the flaps 24, 25, and the intermediate plate 3 is arranged. of the device on the two large flaps 22, 23, superimposed on the lower plate 2, so as to fix the two plates together with each other via said at least one tube 6 on at least one board 2, 3 cooperating with the corresponding through openings 5 on the other board 3, 2 respectively with the layer 7 of flexible material in this board.
  • Said at least one tube 6 is during this step put through the flaps 22, 23, all of the flaps being in their folded closure position of the bag 20.
  • the flexibility of the bag and the flaps facilitates this installation of the closure device 1.
  • Openings are then made in the two flaps 22, 23 at the through holes 5 of the closure device 1 with the aid of adapted points.
  • openings of similar size to the opening 11 of the upper plate 4 of the closure device may be pre-cut in the area corresponding to that of the through holes 5, to obtain an equivalent result. It then remains to integrate the upper plate 4 in the slides 8 of the plate 3 to finalize the installation of the closure device 1 of the invention on the package or the bag 20.
