Definitions

  • the invention relates to a method for making a closure device for a container.
  • the invention also relates to a closure device for a container and to a container equipped with such a device.
  • the transfers between the interior and the exterior of a container should also be limited in order to prevent a degradation of the organoleptic properties or of the taste of a drink such as a fruit juice or mineral water.
  • a drink such as a fruit juice or mineral water.
  • an internal or external coating for example of silica oxide or polyamide, on this body.
  • the leakages of gas are concentrated at the level of the cap of the closure device.
  • the cap cannot be gas-tight by itself.
  • the material used for this pellet is relatively rigid, with the result that it cannot follow the shape of the neck with which it must cooperate sufficiently precisely, this inducing a risk of leakage at the interface between the neck and this pellet.
  • a supple material is used for constituting a seal as in EP-A-0 970 893, this material does not make it possible to limit efficiently the leakages of gas by permeability through the cap.
  • the same plastics material for example of the ethylene/l-butene copolymer type, may possibly be applied in successive layers but is not completely tight since its coefficient of oxygen transfer remains non-zero. Moreover, the seal obtained is not always satisfactory. These imperfect properties of barrier or of seal are a consequence of the necessary compromises to be employed in order to make the same material perform hardly compatible functions.
  • the invention relates to a method for making a closure device in which a cap moulded from plastics material is equipped with a seal adapted to be arranged in abutment against the neck of a container.
  • This method is characterized in that it comprises steps consisting in:
  • the method of the invention minimises the development of germs in the vicinity of the impermeable layer by isolating the latter from the ambient atmosphere thanks to the second layer which forms the seal.
  • This second layer is advantageously made by overmoulding on the first layer, this guaranteeing its adaptation to the exact geometry of the interior of the button (sic).
  • the material of the first layer may be chosen principally for the gas-tight properties of this first layer, while the material of the second layer may be chosen specifically as a function of its elasticity in order to perform its role of seal efficiently.
  • the method comprises a step consisting in overmoulding, by injection or compression, the first layer against the web. Thanks to this aspect of the invention, no interstice can be created between the first layer, which is impermeable, and the bottom web of the cap.
  • the first layer is projected onto the inner surface of the bottom web of the cap.
  • the invention also relates to a closure device capable of being manufactured in accordance with the method described hereinabove and, more precisely, to a closure device which comprises a layer of material impermeable to a predetermined gas or gases interposed between a seal and the bottom web of its cap, this layer being isolated from the ambient atmosphere by this cap and this seal which is made of a material different from that of the layer of gas-impermeable material.
  • this method and this device comprise one or more of the following characteristics:
  • the layer of impermeable material comprises a layer of silica oxide, or of carbon in diamond or amorphous form, integrated in a multi-layer complex arranged against the bottom web and covered with a layer of elastic material forming the seal.
  • the seal is made on the basis of a ethyl vinyl acetate (EVA) copolymer, of elastomer, in particular a derivative of polyamide (PA), of polyamide and/or polyether copolymer.
  • EVA ethyl vinyl acetate
  • PA polyamide
  • This seal may also receive, in its composition, a component which renders it adapted to absorb a gas such as oxygen, in particular the oxygen of the “top empty space” of a bottle and/or the oxygen coming from the product contained in a bottle.
  • the seal is in the overall form of a disc, with a radius substantially equal to the inner radius of the cap, with the result that it efficiently isolates the layer of impermeable material by simply being positioned in the cap.
  • the layer of impermeable material may thus be totally isolated from the outside medium, this allowing this layer to be made with specific materials which could not necessarily be used alone as they are capable of degrading upon contact with the product or with the air.
  • the invention relates to a container for liquid, particularly a bottle made of plastics material, equipped with a closure device such as described hereinabove.
  • a container for liquid particularly a bottle made of plastics material, equipped with a closure device such as described hereinabove.
  • FIG. 1 is a longitudinal section in perspective of a closure device according to the invention, during a first step of manufacture.
  • FIG. 2 is a view similar to FIG. 1 during a second step of manufacture.
  • FIG. 3 is a view on a larger scale of detail III in FIG. 2.
  • FIG. 4 is a view similar to FIG. 1 during a third step of manufacture.
  • FIG. 5 is a view similar to FIG. 1 at the issue of the method for manufacturing the device.
  • FIG. 6 is a view in detail on a larger scale of detail VI in FIG. 5.
  • FIG. 7 is a schematic representation of the closure device of FIGS. 1 to 6 , mounted on the neck of a container.
  • FIG. 8 is a schematic representation of an installation for manufacturing the device of FIGS. 1 to 6 .
  • FIG. 9 is a view similar to FIG. 2 for a device in accordance with a second form of embodiment of the invention.
  • FIG. 10 is a view similar to FIG. 9 during a third step of manufacturing the cap.
  • FIG. 11 is a view similar to FIG. 9 at the issue of manufacture of the device.
  • FIG. 12 is a view on a larger scale of detail XII in FIG. 11.
  • FIG. 13 is a view similar to FIG. 2 for a device in accordance with a third form of embodiment of the invention.
  • FIG. 14 is a view similar to FIG. 6 for the device of FIG. 13.
  • the cap 1 shown in FIGS. 1 to 7 is intended to be mounted on a bottle 2 provided with a neck 3 equipped with an outer threading 4 .
  • the cap 1 is provided with an inner thread 5 .
  • the cap 1 is moulded by compression in a barrel mould 101 of an installation 100 for continuously manufacturing closure devices according to the invention.
  • the cap 1 is moulded from rigid polyethylene, rigid polypropylene, rigid polyamide or from an equivalent material.
  • the complex 6 comprises a core 61 made of polypropylene or PET coated, on a face intended to come into contact with the surface 71 , with an adherence layer 62 made of polyethylene or polypropylene. On its opposite face, the core 61 is coated with a layer 63 of silica oxide which renders the complex 6 tight to oxygen and to carbon dioxide.
  • the complex 6 is placed in position in the cap 1 , as represented by arrow F 1 , by means of an automatic barrel device 102 supplied via a chute 103 from the mould 101 .
  • the afore-mentioned complex 6 might also be formed by:
  • PEN polyethylene napthalate
  • PVA polyvinyl alcohol
  • PPMA polymethylmethacrylate
  • the copolymers of butadiene, styrene, BOPP bi-oriented polypropylene or one of the mixtures thereof may also be used.
  • the material intended to form the seal 8 is deposited on the complex 6 before the introduction of the plunger 9 in the cap 1 .
  • the seal 8 may also be made of PA copolymer and/or polyether.
  • the seal 8 is formed so that it completely isolates and immobilizes the complex 6 against the surface 71 , which has the effect of preventing any development of germs or of bacteria.
  • the seal 8 may form a skirt filling a possible annular space remaining between the complex 6 and the cap 1 .
  • the seal 8 is in the form of a disc and R denotes its radius.
  • R′ denotes the inner radius of the cap 1 in its parts distinct from the thread 5 .
  • the radii R and R′ are substantially equal since the seal 8 extends up to contact with the annular partition 11 of the cap 1 .
  • the closure device formed by elements 1 , 6 and 8 when the closure device formed by elements 1 , 6 and 8 is terminated, it comprises a supple seal 8 capable of easily adapting itself to the geometry of the neck 3 , while the complex 6 , and in particular its layer 63 , opposes any migration of gas from the internal volume V of the bottle 2 towards the outside, this being represented by arrows F 3 , and from the outside towards this volume, this being represented by arrows F 4 in FIG. 7.
  • a cap 201 is provided with a bottom web 207 of which 271 denotes the inner surface.
  • plastics material impermeable to oxygen and to carbon dioxide On this inner surface there is deposited a quantity Q of plastics material impermeable to oxygen and to carbon dioxide. It may be question of polyvinylchloride (PVC), of polyvinylidene chloride (PVDC), of ethylene vinyl alcohol (EVOH), of polyamide or of a mixture based on one of these products.
  • PVC polyvinylchloride
  • PVDC polyvinylidene chloride
  • EVOH ethylene vinyl alcohol
  • PEN polyethylene naphthalate
  • PVA polyvinyl acohol
  • PPMA acrylate copolymer of polyacrylnitrile
  • PPMA polymethylmethacrylate
  • copolymer of butadiene, styrene, bi-oriented polypropylene (BOPP) may be used for this layer.
  • a plunger 110 is then applied on the quantity Q of material to distribute it and compress it so as to form a layer 206 of impermeable material covering the surface 271 .
  • the layer 206 is overmoulded inside the cap 201 .
  • a seal 208 of the type such as seal 108 of the first embodiment is then made in the manner described with reference to FIG. 4 of the first embodiment, which makes it possible to obtain the structure shown in FIGS. 11 and 12 which comprises a first gas-impermeable layer 206 applied on the bottom web 207 of the cap 201 , and a second layer 208 , elastically deformable and capable of being adapted to the exact geometry of the neck of a bottle and, more generally, of any container.
  • the impermeable layer 206 is embedded against the bottom web 207 of the cap 201 by the layer forming seal 208 , with the result that it is efficiently isolated from outside pollutions.
  • the closure device of this second form of embodiment may be obtained thanks to an installation similar to that shown in FIG. 8, the device 102 for positioning the complex 6 of the first embodiment being replaced by a barrel mould, in which the layer 206 is overmoulded.
  • a cap 301 is provided with a bottom web 307 of which 371 denotes the inner surface.
  • a layer 306 forming barrier to the migration of gases such as oxygen and/or carbon dioxide, is projected thanks to a nozzle 311 on the surface 371 , as represented by arrows F 5 .
  • the layer 306 is thus obtained by a deposit of silica oxide. It may also be question of a barrier varnish.
  • the layer 306 might be obtained by metallization. Although this has not been shown, the layer 306 may cover all or part of the inner surface of the annular partition of the cap.
  • a seal 308 is overmoulded on the bottom of the cap 301 , in manner similar to that described with reference to the first embodiment, this seal efficiently isolating the layer 306 from the ambient atmosphere.
  • the layer forming the seal 308 is made of an elastically deformable material adapted to create a tight abutment on the neck of a container.
  • the cap might equally well be moulded by injection.
  • the layer 8 , 208 , 308 forming seal may be made of a material absorbing oxygen. In that case, the second layer protects the first from possible alterations due to the oxygen.
