Definitions

  • the present invention is in the field of packaging and relates more particularly to a container intended to be filled with a product in any form whatsoever (liquid, powder, paste, etc.) and which can, after filling, be closed and opened several times by the consumer so that he can withdraw the desired quantity of product according to his needs, this container allowing a tight closure each time.
  • a product in any form whatsoever (liquid, powder, paste, etc.) and which can, after filling, be closed and opened several times by the consumer so that he can withdraw the desired quantity of product according to his needs, this container allowing a tight closure each time.
  • trays intended especially for foodstuffs.
  • these trays consist of a body made of synthetic material, most often by thermoforming, provided with a cover.
  • Document FR-A-2 651 749 describes a hermetically sealed container, after filling with a liquid, with a cover. In this case, we certainly obtain the original seal and the necessary seal, but the container can only be used for a single use since, once removed, the cover cannot be replaced.
  • Document FR-A-2 656 590 describes, for its part, a tray comprising a body made of synthetic material and closed with a removable cover, also made of synthetic material, by fitting covering a groove provided around the perimeter of the cover, on a rib located around the perimeter of the body.
  • a tray comprising a body made of synthetic material and closed with a removable cover, also made of synthetic material, by fitting covering a groove provided around the perimeter of the cover, on a rib located around the perimeter of the body.
  • the same tray can be opened and then closed several times, but the lid exceeds the outline of the body and can easily be opened by accident.
  • the seal is very uncertain for liquid products.
  • the cover is secured to the body.
  • Containers which have a body and an orifice located at the end of a neck of smaller dimensions:
  • Document US-A-3,380,608 describes a completely molded plastic bottle with a body and a neck. It is made from a thermoformed sheet to present two shells integral and symmetrical with respect to a fold line, which each have a part of the neck, then which are folded towards each other and welded, the plane of seal passing through the neck.
  • the neck is formed of two halves located on either side of the joint plane, so that this neck is not smooth and strictly circular:
  • margins welded in pairs diametrically opposite with respect to the axis of the neck. Internally, at the right of these pairs of margins, it has two small grooves resulting from the inevitable existence of connecting leaves between the interior surface of the neck and the four margins.
  • this bottle is integral with a stopper intended for closing the neck, by means of a tab which is attached not to the bottle itself but to the neck itself.
  • this neck is secured to a radial outer tab carrying a screw cap which can visibly be placed in the closed position only by covering the collar externally, by its pitch.
  • Document FR-A-2,314,877 describes a container which does not have a neck and which cannot be opened and closed successively since it provides for the opening to be made by definitive tearing of a hollow appendage communicating with the interior of the container.
  • Document US-A-3,297,208 describes a container traversed by an interior orifice with a protruding neck, with smooth interior and exterior walls, integral with a shutter for repetitive use which is located on a leg articulated with said container, and not at the neck, and which has a cylindrical part which can be inserted into the neck.
  • the object of the invention is to provide a container having a small orifice relative to the body of said container, originally sealed to guarantee that the content is intact, associated with a shutter for repetitive use with an excellent seal.
  • the subject of the invention is a container crossed by an interior orifice with a protruding neck, with smooth interior and exterior walls, secured to a shutter for repetitive use which is located on a leg articulated to said container, and not at the neck, and which has a cylindrical part which can be inserted into the neck, characterized in that the neck is continuously cylindrical, made of a flexible material, and insulated, that is to say that it projects away from any other relief, the cylindrical part insertable into the neck, having a height at least equal to that of said neck, the inner wall, at least, of the neck and the outer wall, at least, of the cylindrical part being made of synthetic material.
  • Figures 1 to 5 illustrate a first embodiment of a container according to the invention as well as the different steps for obtaining said container.
  • a container 1 is produced in one piece, from a plastic film 2 by thermoforming in a mold 4 provided with suction channels 6, as shown diagrammatically in FIG. 1.
  • the body 10 of the container 1 is first produced by forming two concave parts 12 and 14 as well as an articulated tab 16 formed from the part 12 and provided with a shutter 18.
  • the two concave parts 12 and 14 are joined by one of their edges and the film of synthetic material constitutes, in this area, a hinge 15.
  • the shutter 18 comprises a cylindrical part 30 and a frustoconical end 32, the cylindrical part 30 contributing to the sealing of the shutter as explained below.
  • a filling and emptying orifice 20 is produced on the body 10 in a zone distinct from the edges of the concave parts which form reliefs.
  • a pilot hole 22 is drilled in the face 14 a of the part 14 of the body, in an area facing the shutter 18 after the hinged leg 16 has been folded down. towards part 14.
  • the chosen surface is advantageously flat.
  • the actual orifice is then formed by passing a heating punch 24 through the pilot hole 22, as shown diagrammatically in FIG. 2 b .
  • the heating punch 24 is calibrated to the internal diameter which the orifice 20 must ultimately have.
  • Figure 3 shows the part from the process described above.
  • margins 28 have been provided on the edges of each of the parts 12 and 14, during the thermoforming step.
  • the two parts 12 and 14 are assembled according to the arrow F1 and the margins 28 are joined in pairs, for example by heat sealing, the parts 12 and 14 facing each other by their concavity.
  • the smooth neck 26 is located far from the margins 28 and, in particular, that it is not created partially on the part 12 and partially on the part 14, so that it is not crossed by the plane of seal margins 28.
  • the product is introduced into the container either before the parts 12 and 14 are joined, or after these parts are joined, by the orifice 20.
  • Figures 4 and 5 show the container 1 respectively in the open position and the closed position. It can be seen that in order to close the filling and emptying orifice 20, the articulated tab 16 secured to the part 12 is folded down, towards the part 14 according to the arrow F2. The frusto-conical end 32 of the obturator 18 is then introduced into the orifice 20 and pressure is exerted on it to push it in until the cylindrical part 30 comes into contact with the smooth neck 26.
  • the obturation thus obtained is completely sealed thanks on the one hand to the presence of the cylindrical part 30 of the obturator 18 whose height h 1 is at least equal to the height h 1 'of the smooth neck 26.
  • the outside diameter d 1 of the cylindrical part 30 is substantially equal to the inside diameter d 2 of the smooth neck 26 and on the other hand, thanks to the contact between synthetic material and synthetic material that is created between said cylindrical part 30 and col 26.
  • the user raises the articulated tab 16 in the direction of the arrow F3 to extract the shutter 18 from the orifice 20.
  • the consumer can take the product in small quantities from the container and close the latter with an excellent seal each time.
  • Sealing is called an operation which ensures that the container has not already been opened.
  • connection means initially making the articulated lug 16 provided with the shutter 18 integral with the body 10 of the container 1, these connection means then being annihilated during the first opening of the orifice 20, as described with reference to Figures 6 and 7.
  • the free end 16 a of the articulated lug 16 is made integral with the face 14 a of the body 10 in which the orifice 20 has already been made, far from it and from the smooth neck 26.
  • at least one welding point 40 is created which causes a deformation towards the interior of the container 1 relative to the face 14 a , by applying in a localized and relatively rapid manner, a sufficient heat source. , taking into account the characteristics of the material of the container.
  • This operation carried out after filling and closing the container with the shutter 18, fixes the end 16 a to the face 14 a .
  • sealing is used here only for inviolability and does not participate in any way in the initial closure of the container as in subsequent closings. This is therefore entirely different from certain known containers which are only leaktight by sealing, which means that the seal disappears as soon as it is opened for the first time.
  • FIGS. 4 and 5 the shape of the constituent parts 12 and 14 chosen in the example given here is particularly advantageous. Indeed, these have flat parts 12 b and 14 b , in the region of the hinge 15, which together constitute a base making it possible to place the container 1 in stable equilibrium.
  • the articulated tab 16 provided with the shutter 18 and the filling and emptying orifice 20, are located on constituent parts 12 and 14 different from the body 10, and not partially on the two parts 12 and 14.
  • the articulated lug and the orifice can be on the same constitutive part of the body of the container, since the orifice and its neck , at least, are not partially on two parts at the same time, crossed by the parting line because this arrangement would be opposed to obtaining a good seal of the successive obturations.
  • a container 50 is formed from a synthetic film 52 by thermoforming in a mold 54 having a plurality of suction channels 56.

  • FIG. 9 shows more precisely the position of the film 52 before thermoforming and the structure of the mold 54 in the area of the shutter. Thanks to the presence of the ring 58, there is obtained, after the thermoforming operation, a shutter 68 having on the one hand, a groove 80 defining a cylindrical part 82 and on the other hand, a bottom 84, as can be see it in more detail in Figure 12.
  • the orifice 70 is produced in a manner analogous to the diagram of FIGS. 2 a , 2 b and 2 c for the orifice 20, that is to say, by first making a pilot hole of small diameter then by calibrating it and simultaneously forming a smooth neck 76 by passing a heating punch through this pilot hole.
  • Figure 8 shows the part obtained at the end of the above steps.
  • Margins 78 have been provided during thermoforming, on each of the sides of parts 62 and 64, except of course, at the level of hinge 65.

  • the part 82-84 of the shutter 68 intended to enter the filling and emptying orifice 70 has a slightly frustoconical shape and the outside diameter d 3 of the bottom 84 is substantially equal to the inside diameter d 4 of the neck 76
  • the adjustment of the diameters d 3 and d 4 facilitates the entry of the shutter 68 into the neck 76.
  • the shutter 68 exerts on the neck 76 a push towards the exterior of the orifice 70 which, taking into account, in addition, the elastic properties of the film 52, deforms radially.
  • the closed position is detailed in FIG. 14 and it can be seen that the neck 76 abuts in the bottom of the groove 80.
  • the smooth neck 76 is forced into the groove 80 since the thickness e of the film is slightly greater than the width l of the groove 80, which leads to a very good seal.
  • the insertion of the neck 76 into the groove 80 is possible thanks to the fact that this neck 76 is smooth internally and externally, which allows it to slide against the two opposite faces of the groove 80.
