Description
JOINT THERMOSCELLABLETHERMOSCELLABLE JOINT
L'invention a pour objet un nouveau type de joint thermoscellable. The invention relates to a new type of heat-sealable seal.
L'obturation de récipients par bouchon ou capsule préalablement à leur première ouverture peut être effectuée au moyen de joints thermoscellables. Ces joints comprennent traditionnellement un opercule thermoscellable destiné à être appliqué sur le buvant du récipient, ledit opercule étant associé à un support en contact avec le fond du bouchon ou de la capsule. The closure of containers by cap or capsule prior to their first opening can be performed by means of heat sealable seals. These seals traditionally comprise a heat-sealable seal intended to be applied on the rim of the receptacle, said seal being associated with a support in contact with the bottom of the stopper or the cap.
De manière connue, les opercules dits "thermoscellables" consistent en l'association, au moyen d'agent liant, d'un film plastique choisi en fonction de la nature du matériau constitutif du récipient, avec un film réalisé en un matériau diélectrique, en pratique de l'aluminium, destiné à ramollir par induction ou conduction ledit film plastique avec lequel il est en contact aboutissant au scellement de l'opercule sur le buvant du récipient. In known manner, so-called "heat-sealable" covers consist of the combination, by means of binding agent, of a plastic film chosen according to the nature of the material constituting the container, with a film made of a dielectric material, practice of aluminum, intended to soften by induction or conduction said plastic film with which it is in contact resulting in the sealing of the lid on the rim of the container.
S'agissant du support, les supports traditionnels utilisés sont des mousses polyoléfines et en particulier des mousses de polyéthylène ou de polypropylène d'une épaisseur comprise entre 120 m et 250 m présentant nécessairement, sur au moins la face en contact avec le fond de la capsule, un film PET solidarisé au moyen de colle. La présence de ce film est indispensable en ce qu'elle évite tout risque de thermosoudage du joint sur la capsule au moment de l'opération de thermoscellage, dans la mesure ou les capsules sont généralement réalisées en polypropylène (PP) ou polyethylène haute densité (PEHD). En outre, elle permet, en combinaison avec la feuille d'aluminium, d'améliorer la rigidité du joint évitant ainsi tout risque de sortie accidentelle du joint de la capsule lorsque les opercules thermoscellants sont livrés déjà incorporés dans le fond du bouchon ou de la capsule, l'opération de thermoscellage proprement dite étant effectuée ultérieurement. Enfin, le support permet d'absorber les tolérances entre le fond de la capsule et/ou du bouchon. As regards the support, the traditional supports used are polyolefin foams and in particular foams of polyethylene or polypropylene with a thickness of between 120 m and 250 m necessarily having, on at least the face in contact with the bottom of the capsule, a PET film secured with glue. The presence of this film is essential in that it avoids any risk of heat sealing the seal on the capsule at the time of the heat sealing operation, insofar as the capsules are generally made of polypropylene (PP) or high density polyethylene ( HDPE). In addition, it allows, in combination with the aluminum sheet, to improve the rigidity of the seal thus avoiding any risk of accidental release of the seal of the capsule when the heat sealing lids are delivered already incorporated in the bottom of the cap or the capsule, the heat sealing operation itself being performed later. Finally, the support makes it possible to absorb the tolerances between the bottom of the capsule and / or the stopper.
Le problème que se propose de résoudre l'invention est de mettre au point des joints thermoscellables présentant une structure la plus simple possible en limitant au maximum le nombre d'éléments nécessaires et par conséquent, le coût de fabrication. 1 Le Demandeur a constaté que de manière tout à fait surprenante, la substitution d'une mousse polyoléfine, en particulier de polyéthylène ou de polypropylène, par une mousse polyester permettait de s'affranchir de la présence nécessaire d'un film PET appliqué à la surface du support. En outre, quand bien même un film PET serait appliqué, par exemple pour améliorer l'état de surface du joint, il le serait par coextrusion et non par collage comme c'est le cas dans l'art antérieur. On supprimerait donc dans cette hypothèse une étape dans le procédé de fabrication. The problem to be solved by the invention is to develop heat sealable seals having the simplest structure possible by limiting as much as necessary the number of elements and therefore the cost of manufacture. The Applicant has found that, quite surprisingly, the substitution of a polyolefin foam, in particular of polyethylene or polypropylene, with a polyester foam makes it possible to overcome the need for a PET film applied to the surface of the support. In addition, even if a PET film would be applied, for example to improve the surface state of the seal, it would be by coextrusion and not by bonding as is the case in the prior art. In this case, a step in the manufacturing process would be abolished.
Dès lors, l'invention a pour objet un joint thermoscellable comprenant un support associé à un opercule thermoscellable sur le buvant d'un récipient qui se caractérise en ce que le support se présente sous la forme d'une couche de polyester expansé. Therefore, the subject of the invention is a heat-sealable seal comprising a support associated with a heat-sealable seal on the rim of a receptacle which is characterized in that the support is in the form of an expanded polyester layer.
Selon une première caractéristique, le polyester expansé est choisi dans le groupe comprenant le polyéthylène téréphtalate et l'acide polylactique. According to a first characteristic, the expanded polyester is chosen from the group comprising polyethylene terephthalate and polylactic acid.
Dans un mode de réalisation avantageux, le support est réalisé en PET expansé. In an advantageous embodiment, the support is made of expanded PET.
Dans cette hypothèse, le PET expansé a une densité comprise entre 30 et 500 kg/m2, avantageusement comprise entre 100 et 200 kg/m2 c'est-à-dire une densité moyenne. In this case, the foamed PET has a density of between 30 and 500 kg / m 2, advantageously between 100 and 200 kg / m 2, that is to say a mean density.
Selon une autre caractéristique, l'épaisseur de la mousse PET est comprise entre 50 m et 4 mm, avantageusement entre 100 et 300 m, de préférence de l'ordre de 150 m. According to another characteristic, the thickness of the PET foam is between 50 m and 4 mm, advantageously between 100 and 300 m, preferably of the order of 150 m.
Comme déjà dit, les joints connus de l'art antérieur comprennent un film appliqué par 25 collage à la surface du support destiné à être en contact avec le fond du bouchon. Or, il apparaît qu'un des avantages de la mousse PET, lié à ses caractéristiques mécaniques, est de pouvoir s'affranchir de ce film. Néanmoins et dans un autre mode de réalisation, pour améliorer l'état de surface de la mousse PET, ladite mousse présente sur sa face destinée à être en contact avec le fond du bouchon, un film de PET appliqué par coextrusion. 30 Selon une autre caractéristique, la partie opercule du joint est thermoscellable. As already stated, the known prior art seals comprise a film adhered to the surface of the support intended to be in contact with the bottom of the plug. However, it appears that one of the advantages of PET foam, related to its mechanical characteristics, is to be able to overcome this film. Nevertheless, and in another embodiment, to improve the surface state of the PET foam, said foam has on its face intended to be in contact with the bottom of the stopper, a PET film applied by coextrusion. According to another feature, the seal portion of the seal is heat sealable.
Dans ce cas, l'opercule est obtenu par association d'une feuille supérieure réalisée en un matériau diélectrique, avantageusement l'aluminium, d'une épaisseur comprise en 20 3 pratique entre 5 et 50 m, avantageusement entre 7 et 40 m et d'un film thermoscellant dont la nature est fonction de la matière constitutive du récipient. In this case, the cover is obtained by combining an upper sheet made of a dielectric material, advantageously aluminum, having a thickness of between 5 and 50 m, advantageously between 7 and 40 m, and a heat-sealing film whose nature is a function of the constituent material of the container.
En pratique, le film thermoscellant est réalisé en un matériau choisi dans le groupe comprenant le polyéthylène, le polypropylène ou le polyester. In practice, the heat-sealing film is made of a material chosen from the group comprising polyethylene, polypropylene or polyester.
Selon une autre caractéristique, la feuille d'aluminium et le film thermoscellant sont associés au moyen d'un liant tel que par exemple une colle bicomposant isocyanate - hydroxyle. According to another characteristic, the aluminum foil and the heat-sealing film are combined by means of a binder such as, for example, an isocyanate-hydroxyl two-component adhesive.
Dans un mode de réalisation perfectionné, la feuille d'aluminium est séparée du film thermoscellant par un film plastique, de polypropylène orienté, ou avantageusement de PET destiné à renforcer l'indéchirabilité du joint. Dans ce cas, le film plastique est solidarisé au film thermoscellant par collage au moyen d'une colle du type par exemple colle bicomposant isocyanate - hydroxyle. In an improved embodiment, the aluminum foil is separated from the heat-sealing film by a plastic film, oriented polypropylene, or preferably PET to enhance the joint's non-tearability. In this case, the plastic film is secured to the heat-sealing film by gluing with a glue of the type, for example two-component isocyanate-hydroxyl glue.
Dans un mode de réalisation préféré, l'opercule et le support sont associés au moyen d'un liant permanent, par exemple du type colle bicomposant isocyanate - hydroxyle. In a preferred embodiment, the lid and the support are associated by means of a permanent binder, for example of the two-component isocyanate-hydroxyl glue type.
Dans un autre mode de réalisation, lorsque l'utilisateur souhaite disposer d'un joint désolidarisable, c'est-à-dire d'un joint dont le support se sépare de l'opercule au moment de l'ouverture du récipient, l'opercule et le support sont associés au moyen d'un liant temporaire. Le liant temporaire est avantageusement du polyéthylène modifié ou un copolymère éthylène vinyl acétate. Dans un mode de réalisation particulier, le liant contient deux copolymères polyéthylène-monomère vinylique distincts. In another embodiment, when the user wishes to have a releasable seal, that is to say a seal whose support separates from the lid at the time of opening of the container, the operculum and the support are associated by means of a temporary binder. The temporary binder is advantageously modified polyethylene or an ethylene vinyl acetate copolymer. In a particular embodiment, the binder contains two different polyethylene-vinyl monomer copolymers.
Bien entendu, la forme du joint thermoscellable de l'invention sera déterminée en fonction de la forme du bouchon. Of course, the shape of the heat-sealable gasket of the invention will be determined according to the shape of the plug.
L'invention et les avantages qui en découlent ressortiront bien de la description à l'appui des figures annexées. The invention and the advantages which result therefrom will emerge from the description in support of the appended figures.
La figure 1 est un schéma en coupe du joint thermoscellable de l'invention. La figure 2 est une vue en coupe d'un second mode de réalisation du joint thermoscellable de l'invention. Figure 1 is a sectional diagram of the heat sealable seal of the invention. Figure 2 is a sectional view of a second embodiment of the heat seal seal of the invention.
Le joint scellable de l'invention présente deux parties, respectivement un support (1) et un opercule thermoscellant (2), l'opercule et le support étant réunis au moyen d'un adhésif permanent (3) tel qu'une colle bicomposant isocyanate ù hydroxyle. Le support selon l'invention se présente sous la forme d'une mousse polyéthylène téréphtalate (4) d'une épaisseur de 150 m et d'une densité égale à 150 kg/m2. The sealable seal of the invention has two parts, respectively a support (1) and a heat-sealable seal (2), the seal and the support being joined by means of a permanent adhesive (3) such as a two-component isocyanate adhesive hydroxyl. The support according to the invention is in the form of a polyethylene terephthalate foam (4) with a thickness of 150 m and a density of 150 kg / m 2.
La partie opercule est traditionnellement obtenue par association d'une feuille 10 d'aluminium (5) d'épaisseur égale à 20 m et d'un film thermoscellable (6) de polyéthylène basse densité d'épaisseur 40 m. La feuille d'aluminium et le film thermoscellable sont associés au moyen d'un liant (7) sous forme d'une colle bicomposant isocyanate ù hydroxyle. The operculum portion is conventionally obtained by combining an aluminum foil (5) with a thickness of 20 m and a heat-sealable film (6) of low density polyethylene with a thickness of 40 m. The aluminum foil and the heat-sealable film are combined by means of a binder (7) in the form of a two-component isocyanate-hydroxyl glue.
15 Dans un second mode de réalisation, représenté sur la figure 2, l'opercule présente, entre la feuille d'aluminium (5) et le film thermoscellable (6), un film supplémentaire de polyéthylène téréphtalate (9) rendu solidaire du film thermoscellable au moyen, d'un liant identique au précédent. In a second embodiment, shown in FIG. 2, the lid has, between the aluminum foil (5) and the heat-sealable film (6), an additional film of polyethylene terephthalate (9) made integral with the heat-sealable film. by means of a binder identical to the previous one.
20 L'invention et les avantages qui en découlent ressortent bien de la description qui précède. On note en particulier la substitution des complexes mousse PE/ film PET par une simple mousse PET qui permet de simplifier la fabrication et diminuer le coût des joints. 25 The invention and the advantages thereof are apparent from the foregoing description. In particular, the substitution of the PE foam / PET film complexes by a simple PET foam makes it possible to simplify the manufacture and reduce the cost of the joints. 25
