Description

ENSEMBLE DE BOUCHAGE POUR EMBALLAGE ET PKOCEDE D'OBTURATION D'EMBALLAGE PACKAGING ASSEMBLY FOR PACKAGING AND PKOCEDE PACKING SHUTTER
La présente invention concerne, de façon générale, le domaine des emballages pour produits consommables dont la conservation nécessite un certain niveau d'asepsie de l' emballage.The present invention relates generally to the field of packaging for consumables whose conservation requires a certain level of asepsis of the packaging.
Plus particulièrement, l'invention concerne un ensemble de bouchage pour un emballage destiné à contenir un produit consommable comportant une embase ayant une première partie adaptée pour être assemblée avec l'emballage et un bouchon adapté pour être assemblé avec une deuxième partie de l'embase et pour obturer une ouverture pratiquée dans cette embase, cette ouverture de l'embase débouchant sur une face de contact avec le produit de l'embase, cette face de contact de l'embase étant sensiblement plane et destinée à être mise en regard avec l'intérieur de l' emballage.More particularly, the invention relates to a closure assembly for a package for containing a consumable product comprising a base having a first portion adapted to be assembled with the package and a cap adapted to be assembled with a second portion of the base and to close an opening made in this base, this opening of the base opening on a contact face with the product of the base, this contact face of the base being substantially flat and intended to be placed in line with the inside the packaging.
Il est connu notamment dans le domaine des emballages souples ou semi rigides d'avoir des embases en matière plastique rigide adaptées pour être assemblées avec l'emballage. Une embase comporte une ouverture traversant l'embase afin de réaliser un passage entre l'intérieur et l'extérieur de l'emballage et permettre ainsi la distribution du produit contenu dans l'emballage. L'embase est adaptée pour, recevoir un bouchon d'obturation de l'ouverture afin de rendre étanche l'ouverture lorsque le bouchon est assemblé avec 1' embase .It is known in particular in the field of flexible or semi-rigid packaging to have rigid plastic bases adapted to be assembled with the packaging. A base comprises an opening through the base to make a passage between the inside and outside of the package and thus allow the distribution of the product contained in the package. The base is adapted to receive a closure cap of the opening to seal the opening when the cap is assembled with one base.
Pour éviter les risques de dégradation du produit contenu dans l'emballage, et pour des questions d'hygiène il est nécessaire d'aseptiser toutes les parties de l'emballage, de l'embase et du bouchon qui peuvent entrer en contact avec ce produit.To avoid the risk of degradation of the product contained in the packaging, and for hygiene reasons it is necessary to sanitize all parts of the packaging. the packaging, the base and the plug that may come into contact with this product.
Pour cela, le bouchon et l'embase sont fabriqués puis aseptisés et insérés dans un suremballage étanche afin d'être stockés et transportés vers le lieu de conditionnement de produit. Sur le lieu de conditionnement on extrait alors le bouchon et l' embase du suremballage de protection hygiénique puis on assemble l'embase et l'emballage, on remplit l'emballage du produit à conserver et enfin on obture définitivement l'emballage contenant ce produit.For this, the cap and the base are manufactured and sanitized and inserted into a sealed overpack to be stored and transported to the product packaging site. At the place of packaging then extract the cap and the base of the hygienic overwrap and then assemble the base and the packaging, fill the packaging of the product to be preserved and finally permanently closes the packaging containing this product .
Pour éviter les risques de contamination du produit, les opérations d'assemblage de l'emballage avec l'embase et le bouchon ainsi que l'opération de remplissage de l'emballage sont réalisées dans un environnement aseptisés par exemple sous un flux d' air laminaire purifié.To avoid the risk of contamination of the product, the assembly operations of the package with the base and the cap and the filling operation of the packaging are performed in a sanitized environment for example under a stream of air purified laminar.
Un ensemble de bouchage pour un emballage du type précédemment défini est par exemple présenté dans le document brevet WO03/06461. Cet ensemble de l'art antérieur qui est représenté sur la figure 2 comporte une embase 1 dont l'ouverture 2 s'étend depuis la base de l'embase jusqu'à former une portion tubulaire allongée 3 permettant de verser le produit. Le bouchon 4 possède une collerette interne de forme complémentaire du rebord interne supérieur 5 de l'ouverture 2 permettant ainsi un assemblage étanche entre le bouchon et l'embase à l'extrémité de la portion tubulaire allongée 3.A closure assembly for a package of the type previously defined is for example presented in the patent document WO03 / 06461. This assembly of the prior art which is shown in Figure 2 comprises a base 1 whose opening 2 extends from the base of the base to form an elongate tubular portion 3 for pouring the product. The plug 4 has an internal flange of complementary shape of the upper internal flange 5 of the opening 2 thus allowing a tight connection between the plug and the base at the end of the elongated tubular portion 3.
Un tel ensemble de bouchage est difficilement stérilisable en ligne car il comporte de nombreux replis, zones creuses pouvant contenir des impuretés. Seules des techniques de stérilisation par ionisation ou par bain chimique permettent d'obtenir une stérilisation acceptable mais ces techniques présentent des inconvénients et peuvent laisser des traces sur le bouchon et l'embase (traces de radioactivité ou traces chimiques) .Such a closure assembly is difficult to sterilize online because it has many folds, hollow areas may contain impurities. Only ionization or bath sterilization techniques chemical allow to obtain an acceptable sterilization but these techniques have drawbacks and may leave traces on the cap and the base (traces of radioactivity or chemical traces).
Dans ce contexte, la présente invention a pour but de proposer un ensemble de bouchage pour un emballage ainsi qu'un procédé d'obturation d'un emballage facilitant la mise en œuvre d'une stérilisation en ligne de l'ensemble.In this context, the present invention aims to provide a closure assembly for a package and a method of sealing a package facilitating the implementation of online sterilization of the assembly.
A cette fin, l'ensemble de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule défini précédemment, est essentiellement caractérisé en ce que le bouchon comporte une portion d'obturation de forme complémentaire de l'ouverture de l'embase telle qu'une fois le bouchon assemblé avec l'embase, la portion d'obturation est montée étanche avec au moins une zone de l'ouverture située à l'endroit ou à proximité immédiate de ladite face de contact de l'embase, la portion d'obturation du bouchon comportant en outre une face d'extrémité de contact avec le produit, sensiblement plane, telle qu'une fois le bouchon. assemblé avec l'embase, lesdites faces de contact respectives, du bouchon et de l'embase sont sensiblement coplanaires.To this end, the assembly of the invention, furthermore in accordance with the generic definition given in the preamble defined above, is essentially characterized in that the plug comprises a shutter portion of shape complementary to the opening of the base such that once the cap is assembled with the base, the closing portion is sealed with at least one area of the opening located at or in the immediate vicinity of said contact face of the base, the closure portion of the plug further comprising a substantially contact-like end surface of the product, such as once the plug. assembled with the base, said respective contact faces, the plug and the base are substantially coplanar.
Pour la compréhension de la présente invention, il est à noter que le terme face de contact avec le produit de l'embase, désigne une surface de l'embase s' inscrivant sensiblement dans un plan et sur laquelle débouche l'ouverture. Une telle surface plane de l'embase peut être par exemple une couronne plane 9 au centre de laquelle débouche l'ouverture, comme c'est par exemple le cas sur la figure 2. La surface de l'ensemble de l'invention devant être mise en contact avec le produit est sensiblement plane et est formée par une face de contact appartenant au bouchon et par une face de contact appartenant à l' embase. Grâce à cette disposition coplanaire des faces de contact respectives de l'embase et du bouchon, la surface à stériliser ne comporte pratiquement pas de zones d'ombres, ou de creux, ou replis, facilitant ainsi la stérilisation.For the understanding of the present invention, it should be noted that the term contact face with the product of the base, designates a surface of the base s' registering substantially in a plane and on which opens the opening. Such a flat surface of the base may be for example a flat ring 9 in the center of which opens the opening, as is the case, for example, in FIG. 2. The surface of the assembly of the invention to be brought into contact with the product is substantially flat and is formed by a contact surface belonging to the plug and a contact surface belonging to the base. Thanks to this coplanar arrangement of the respective contact faces of the base and the plug, the surface to be sterilized has virtually no areas of shadows, or recesses, or folds, thus facilitating sterilization.
Pour la compréhension de la présente invention le terme « sensiblement » utilisé dans les expressions « face de contact avec le produit sensiblement plane », « face d'extrémité de contact avec le produit, sensiblement plane » et « lesdites faces de contact respectives du bouchon et de l'embase sont sensiblement coplanaire » précise que ces faces, ont des formes planes et coplanaire aux imprécisions prêts et dans la seule mesure où ces imprécisions sont suffisamment faibles pour que des zones d'ombres ne soient pas générées au niveau des faces de contact avec le produit lors d' une stérilisation par lumière puisée.For the understanding of the present invention the term "substantially" used in the expressions "contact face with the substantially flat product", "product contact end face, substantially flat" and "said respective contact faces of the plug and the base are substantially coplanar "said that these faces, have flat shapes and coplanar inaccuracies ready and only to the extent that these inaccuracies are low enough that shadows are not generated at the faces of contact with the product during pulsed light sterilization.
Grâce à l'invention, il est possible d'effectuer une stérilisation en ligne par lumière puisée en éclairant simplement la surface plane formée par les faces de contact du bouchon et de l'embase. L'ensemble de l'invention est donc avantageux d'un point de vu hygiénique et également économique car l'opération de stérilisation peut être accélérée sans nuire à la qualité de la stérilisation.Thanks to the invention, it is possible to perform a line sterilization by pulsed light by simply illuminating the flat surface formed by the contact faces of the plug and the base. The whole of the invention is therefore advantageous from a hygienic point of view and also economical because the sterilization operation can be accelerated without affecting the quality of the sterilization.
A cette même fin, l'invention porte également sur un procédé d'obturation d'un emballage caractérisé en ce que : on fournit un emballage adapté pour contenir un produit consommable ou des éléments constitutifs dudit emballage, une embase ayant une face sensiblement plane de contact avec le produit, l'embase comportant une ouverture débouchant sur la face de contact de l' embase et un bouchon adapté pour être assemblé avec l'embase et pour en obturer l'Ouverture, ce bouchon présentant une face de contact avec le produit ; on assemble le bouchon avec l'embase de telle manière qu'une portion d'obturation du bouchon soit montée étanche avec au moins une zone de l'ouverture située à l'endroit, ou à proximité immédiate, de ladite face de contact de l'embase et de telle manière que lesdites faces de contact respectives, du bouchon et de l'embase soient sensiblement coplanaires entre elles ; on aseptise lesdites faces de contact coplanaires ; on assemble l'emballage ou les éléments constitutifs de l'emballage avec une première partie de l'embase de telle manière que les faces de contact aseptisées, de l'embase et du bouchon, soient en vis-à- vis avec l'intérieur de l'emballage.For the same purpose, the invention also relates to a method for sealing a package, characterized in that: a package adapted to contain a consumable product or constituent elements of said package is provided, a base having a substantially flat face of contact with the product, the base having an opening opening on the contact face of the base and a suitable cap to be assembled with the base and to close the opening, this plug having a contact surface with the product; the plug is assembled with the base in such a way that a closing portion of the plug is sealed with at least one zone of the opening located at or in the immediate vicinity of said contact face of the base and such that said respective contact faces, the plug and the base are substantially coplanar with each other; said coplanar contact faces are sanitized; the packaging or the constituent elements of the packaging are assembled with a first part of the base in such a way that the sanitized contact faces of the base and the plug are in facing relation with the inside. of the packaging.
On peut également faire en sorte que l'on aseptise les faces de contact coplanaires du bouchon et de l'embase par un rayonnement lumineux puisé tel qu'un rayonnement ultraviolet.It is also possible to ensure that the coplanar contact faces of the plug and the base are sanitized by pulsed light radiation such as ultraviolet radiation.
Il est également possible en référence à l'ensemble de l'invention qu'une fois le bouchon assemblé avec l'embase, les faces de contact du bouchon et de l'embase soient au plus éloignées l'une de l'autre d'une distance de 1 mm et préférentiellement de 0.5 mm, préférentiellement inférieure à 0.1 mm. Ce mode de réalisation précise que les faces de contact du bouchon et de l'embase sont considérées comme sensiblement coplanaires et sensiblement planes si elles sont éloignées entre elles d'au plus 1 millimètre.It is also possible with reference to the assembly of the invention that once the plug is assembled with the base, the contact faces of the plug and the base are at most distant from each other. a distance of 1 mm and preferably of 0.5 mm, preferably less than 0.1 mm. This embodiment specifies that the contact faces of the plug and the base are considered substantially coplanar and substantially flat if they are distant from each other by at most 1 millimeter.
On cherche en effet à réduire au maximum la distance entre les faces de contact respectives du bouchon et de l'embase pour minimiser les zones dr ombres qui pourraient nuire à la qualité de la stérilisation.Indeed, we try to minimize the distance between the respective contact surfaces of the cap and base to minimize areas r shadows that could harm the quality of sterilization.
On peut également faire en sorte qu'une fois le bouchon assemblé avec l'embase la face de contact du bouchon et la face de contact de l'embase forment une surface dont le défaut de rugosité est inférieur à 100 μm et préférentiellement inférieur à 10 μm. Pour les mêmes raisons de qualité de stérilisation, on cherche à ce que la rugosité de la surface formée par les faces de contact soit la plus faible possible.It can also be ensured that once the plug assembled with the base the contact face of the plug and the contact face of the base form a surface whose roughness defect is less than 100 microns and preferably less than 10. .mu.m. For the same reasons of sterilization quality, it is sought that the roughness of the surface formed by the contact faces is as low as possible.
On peut également faire en sorte que l'ensemble comprenne un emballage souple ayant la forme d'une poche et que l'embase soit assemblée avec cet emballage pour en permettre l'obturation.It can also be ensured that the assembly comprises a flexible packaging in the form of a pocket and that the base is assembled with this packaging to allow sealing.
On peut également faire en sorte que le bouchon et l'embase soient dans des matériaux différents l'un de l'autre. La différence de matériau entre l'embase et le bouchon est avantageuse car il est ainsi possible de conférer certaines propriétés au bouchon et certaines autres propriétés à l'embase. Par exemple on peut faire en sorte que le matériau constitutif du bouchon ait une dureté supérieure à la dureté du matériau constitutif de l'embase (évitant ainsi que le bouchon ne se détériore par écrasement contre l'embase) et/ou que le matériau constitutif de l'embase ait une température de fusion inférieure à la température de fusion du matériau constitutif du bouchon (évitant ainsi un risque de soudure de l'embase avec le bouchon notamment lors de l'assemblage de l'emballage sur l'embase).It can also ensure that the cap and the base are in different materials from one another. The difference in material between the base and the plug is advantageous because it is thus possible to confer certain properties to the plug and some other properties to the base. For example, it is possible to ensure that the material constituting the plug has a hardness greater than the hardness of the material constituting the base (thus preventing the plug from deteriorating by crushing against the base) and / or that the constituent material the base has a melting temperature lower than the melting temperature of the material constituent of the cap (thus avoiding a risk of welding the base with the cap especially during assembly of the package on the base).
Dans ces conditions, on peut faire en sorte que le matériau constitutif du bouchon soit du PEHD (c'est-à- dire du polyéthylène haute densité) ou du PP (c'est-à- dire du polypropylène) et que le matériau constitutif de l'embase soit du PEHD ou du PEBD (c'est-à-dire du polyéthylène basse densité) .Under these conditions, it is possible to ensure that the material constituting the plug is HDPE (that is to say high density polyethylene) or PP (that is to say polypropylene) and that the constituent material the base is HDPE or LDPE (that is to say low density polyethylene).
On peut également faire en sorte que l' embase comporte un filetage femelle situé à l'intérieur de l'ouverture et que le bouchon comporte un filetage mâle complémentaire dudit filetage femelle permettant ainsi de fileter une portion du bouchon dans l'ouverture de l'embase jusqu'à ce que le bouchon et l'embase soient assemblés avec lesdites faces de contact respectives, du bouchon et de l'embase sensiblement coplanaires.It is also possible for the base to have a female thread located inside the opening and for the cap to have a male thread complementary to said female thread, thus making it possible to thread a portion of the plug into the opening of the opening. base until the cap and the base are assembled with said respective contact faces, the cap and the substantially coplanar base.
Grâce au positionnement de du filetage entre le bouchon et l'embase à l'intérieur de l'ouverture, la zone extérieure de l'embase peut être exempte de filetage et peut être lisse ce qui en facilite l'accès lors du nettoyage et améliore l'ergonomie de l'embase dans le cas où l'embase est destinée à être mise en bouche (par exemple lorsque l'embase est montée sur une gourde) .Thanks to the positioning of the thread between the plug and the base inside the opening, the outer zone of the base can be thread-free and can be smooth which facilitates access during cleaning and improves the ergonomics of the base in the case where the base is intended to be put in the mouth (for example when the base is mounted on a gourd).
On peut également faire en sorte que le bouchon et l'embase possèdent des zones de butées axiales pour limiter l'enfoncement du bouchon dans l'ouverture de l'embase lorsque les faces de contact du bouchon et de l'embase sont coplanaires.It can also be ensured that the plug and the base have axial abutment areas to limit the depression of the plug in the opening of the base when the contact faces of the plug and the base are coplanar.

Comme annoncé précédemment, l'invention concerne le domaine des ensembles pour le bouchage d'emballages et pour le conditionnement de produit consommable.As previously announced, the invention relates to the field of assemblies for the closure of packaging and for the packaging of consumable product.
La figure 1 représente un emballage connu par exemple pour l'emballage de liquide ou produits pâteux alimentaires tels que de la compote ou de la mayonnaise.FIG. 1 represents a known packaging, for example for the packaging of liquid or pasty food products such as compote or mayonnaise.
Ce type d'emballage est formé de deux films souples mis en vis-à-vis l'un par rapport à l'autre et soudés généralement par thermo soudage ou soudure ultrason ou collage au niveau de leurs périphéries 15 respectives . Le produit à conserver est introduit dans la zone creuse ainsi définie entre les films grâce aux soudures périphériques 15.This type of packaging is formed of two flexible films placed opposite each other and welded generally by thermo welding or ultrasonic welding or bonding at their respective peripheries. The product to be preserved is introduced into the hollow zone thus defined between the films thanks to the peripheral welds 15.
I/ embase 1 sur laquelle est assemblé le bouchon 4 est positionnée dans un passage réservé à la périphérie des films. Chacun des films est soudé avec une première partie de l'embase, à l'endroit du passage réservé, permettant d'une part de lier l'embase à l'emballage et d'autre part de définir une zone rigide pour l'ouverture et la fermeture de l'emballage et pour la distribution de produit ou le remplissage de l'emballage.I / base 1 on which is assembled the plug 4 is positioned in a passage reserved for the periphery of the films. Each of the films is welded with a first part of the base, at the place of the reserved passage, allowing on the one hand to bind the base to the package and on the other hand to define a rigid zone for opening and closing the package and for dispensing product or filling the package.
Comme le montre la figure 3 qui représente également une embase et un bouchon de l'art antérieur, la première partie 6 de l'embase 1 qui est adaptée pour être assemblée avec les films 7 possède une section transversale en forme d'œil dont le pourtour est effilé en deux zones diamétralement opposées. Ces zones effilées permettent un écartement progressif des films à l'endroit de la première partie 6 de l'embase 1 ce qui évite les pliures des films facilitant d'autant la soudure des films avec l'embase 1.As shown in Figure 3 which also shows a base and a stopper of the prior art, the first part 6 of the base 1 which is adapted to be assembled with the films 7 has an eye-shaped cross-section whose The rim is tapered into two diametrically opposite areas. These tapered zones allow a progressive separation of the films at the location of the first part 6 of the base 1 which avoids the folds of the films facilitating all the welding of the films with the base 1.
La figure 4 est une vue en coupe de l'ensemble de l'invention avec une vue partielle de l'emballage 7 avant son assemblage avec la première partie 6 de l'embase 1.Figure 4 is a sectional view of the assembly of the invention with a partial view of the package 7 before its assembly with the first part 6 of the base 1.
L'embase 1 possède une face de contact alimentaire 9 destinée à être mise en vis-à-vis avec l'intérieur de l'emballage 7. Une ouverture 2 de forme cylindrique est formée au travers de l'embase 1 et s'étend selon un axe de longitudinal d'ouverture 17. Cette ouverture 2 est disposée de façon que l'axe longitudinal 17 soit sensiblement perpendiculaire à la face de contact alimentaire 9 et que l'ouverture 2 ait une extrémité débouchante sur la face 9 et une autre extrémité débouchante à l'opposé de la face 9, de l'autre côté de l' embase .The base 1 has a food contact face 9 intended to be put face to face with the inside of the package 7. A cylindrical opening 2 is formed through the base 1 and extends along an axis of longitudinal opening 17. This opening 2 is arranged so that the longitudinal axis 17 is substantially perpendicular to the food contact face 9 and the opening 2 has one end opening on the face 9 and another open end opposite the face 9 on the other side of the base.
Le bouchon 4 qui s'étend au travers de l'ouverture 2 possède une face de contact alimentaire 12 formée à une extrémité et disposée pour être mise en vis-à-vis avec l'intérieur de l'emballage et avec le produit emballé.The plug 4 which extends through the opening 2 has a food contact face 12 formed at one end and arranged to face the inside of the package and with the packaged product.
Cette face de contact 12 -du bouchon est prévue pour être coplanaire avec la face de contact de l'embase 9 lorsque le bouchon est assemblé avec l'embase comme c'est le cas sur les figures 4 et 6.This contact face 12 of the plug is intended to be coplanar with the contact face of the base 9 when the plug is assembled with the base as is the case in Figures 4 and 6.
Grâce à cette disposition, la surface formée par la face 9 et la face 12 est plane et sans zone d'ombre. Il est donc aisé d'aseptiser les portions 9, 12 de l'embase 1 et du bouchon 4 qui vont être mises en contact avec le produit en les éclairant, en ligne, à l'aide d'une simple source lumineuse puisée.With this arrangement, the surface formed by the face 9 and the face 12 is flat and without shadow area. It is therefore easy to sanitize the portions 9, 12 of the base 1 and the cap 4 which will be brought into contact with the product by illuminating them, in line, using a simple pulsed light source.
Une fois les faces 9 et 12 aseptisées chaque film est positionné en vis-à-vis d'une face de la première partie 6 de l'embase de telle manière que les portions effilées 16a et 16b de la première partie de l'embase aillent en s' effilant jusqu'à rejoindre un plan coplanaire aux films d' emballage 7.Once the faces 9 and 12 sanitized each film is positioned vis-à-vis a face of the first portion 6 of the base so that the tapered portions 16a and 16b of the first part of the base go tilting to a coplanar plan for packaging films 7.
Enfin les films 7, qui sont également aseptisés, sont soudés ou collé le long de leurs périphéries.Finally the films 7, which are also sanitized, are welded or glued along their peripheries.
La figure 5 représente le bouchon 4 de l'invention avant sont assemblage avec l'embase 1 de l'invention. Le bo-uchon 4 est une première pièce monobloc en plastic et l'embase 1 forme une seconde pièce monobloc également en plastic, ces plastics étant de nature différente pour éviter les, risques de soudure/collage entre l'embase et le bouchon. Le bouchon comporte une portion tubulaire cylindrique creuse sur une majeur partie de sa longueur ce qui permet de réduire la quantité de matière injectée à refroidir, réduisant d'autant le temps de démoulage du bouchon et son coût de production. Cette portion tubulaire cylindrique du bouchon est complètement obturée à une de ses extrémités par la face de contact alimentaire 12 perpendiculaire à l'axe longitudinal 17 du bouchon.Figure 5 shows the plug 4 of the invention before being assembled with the base 1 of the invention. The bo-uchon 4 is a first one-piece plastic part and the base 1 forms a second piece monobloc also plastic, these plastics being of different nature to avoid the risk of welding / bonding between the base and the plug. The cap has a hollow cylindrical tubular portion over a major portion of its length which reduces the amount of injected material to be cooled, thereby reducing the release time of the plug and its production cost. This cylindrical tubular portion of the plug is completely closed at one of its ends by the food contact face 12 perpendicular to the longitudinal axis 17 of the plug.
La zone de l'Ouverture 2 de l'embase 1 avec laquelle la portion d' obturation 10 du bouchon est montée étanche est constituée par un rétrécissement de l'extrémité de l'ouverture qui est adjacente à la face de contact de l'embase. Cette zone de l'ouverture rétrécie est formée par un alésage cylindrique de diamètre inférieur au reste de l'ouverture.The region of the opening 2 of the base 1 with which the sealing portion 10 of the cap is sealingly mounted is constituted by a narrowing of the end of the opening which is adjacent to the contact face of the base . This area of the narrowed opening is formed by a cylindrical bore of smaller diameter than the remainder of the opening.
La portion d'obturation 10 du bouchon a une forme complémentaire de zone de l'ouverture telle que lorsque le bouchon est assemblé avec l'embase, la portion d'obturation est alors serrée uniquement à sont extrémité, dans la zone de l'ouverture 2 pour permettre une étanchéité exclusivement localisée à la périphérie de la portion d'obturation 10.The closing portion 10 of the plug has a complementary shape of the opening area such that when the plug is assembled with the base, the closing portion is then clamped only at its end, in the zone of the opening. 2 to allow sealing exclusively localized at the periphery of the sealing portion 10.
La portion d' obturation 10 de forme annulaire est lisse et adjacente à la face de contact 12, ce qui réduit ainsi au maximum les zones creuses situées entre les faces de contact 9, 12 et la zone d' étanchéité .The annular closure portion 10 is smooth and adjacent to the contact face 12, thereby minimizing the hollow areas between the contact faces 9, 12 and the sealing area.
La zone d' étanchéité est de surface réduite ce qui facilite les efforts de dévissage du bouchon qui ne doivent pas dépasser 10 N*m-1.The sealing zone is of reduced surface which facilitates the unscrewing efforts of the plug which must not exceed 10 N * m-1.
Un filetage annulaire 14 est formé sur la périphérie de la portion tubulaire du bouchon de manière à se fileter avec un filetage complémentaire 13 disposé à l'intérieur de l'ouverture 2 de l'embase 1. Ces filetages 13, 14 permettent de forcer le bouchon dans l'ouverture 2 jusqu'à ce qu'il y ait une étanchéité et jusqu'à ce que les faces 9 et 12 soient coplanaires.An annular thread 14 is formed on the periphery of the tubular portion of the stopper. to be threaded with a complementary thread 13 disposed inside the opening 2 of the base 1. These threads 13, 14 make it possible to force the plug into the opening 2 until there is a seal and until the faces 9 and 12 are coplanar.
Les filetages permettent de visser ou dévisser le bouchon de l' embase entre H et 5 tours au maximum, pour cela on peut prévoir que les filetages comprennent plusieurs spirales.The threads make it possible to screw or unscrew the plug of the base between H and 5 turns to the maximum, for this reason it is possible for the threads to comprise several spirals.
Le bouchon comporte une portion extérieure de préhension 18 permettant sa manipulation notamment lorsque l'utilisateur souhaite retirer le bouchon pour verser le produit contenu dans l'emballage.The cap has an outer gripping portion 18 allowing its handling especially when the user wishes to remove the cap to pour the product contained in the package.
Une bague d' inviolabilité 19 est intégrée au bouchon 4 pour venir se cliper dans une gorge externe complémentaire 20 formée sur l'embase 1.A tamperproof ring 19 is integrated in the plug 4 to snap into a complementary external groove 20 formed on the base 1.
Cette bague est reliée au bouchon par des picots de faible résistance mécanique et possèdes des ergots 21 qui une fois engagés dans la gorge 20 empêchent les déplacements axiaux de la bague 19 selon l'axe 17. Ainsi, lorsque l'utilisateur souhaite dévisser le bouchon pour le retirer de l'ouverture 2, une traction s'exerce sur la bague qui retenue par les ergots 21 jusqu'à ce que les picots 22 finissent par se rompre et libérer le bouchon.This ring is connected to the cap by pins of low mechanical strength and has pins 21 which once engaged in the groove 20 prevent axial displacements of the ring 19 along the axis 17. Thus, when the user wishes to unscrew the cap to remove it from the opening 2, traction is exerted on the ring which retained by the lugs 21 until the pins 22 eventually break and release the cap.
Ce système permet d'indiquer à l'utilisateur que l'emballage a déjà été ouvert.This system makes it possible to indicate to the user that the package has already been opened.
L'invention permet d'améliorer les conditions de stockage du produit consommable en assurant une meilleure asepsie de l'embase et du bouchon. L'invention peut être utilisée pour le conditionnement de pâte ou un liquide alimentaire ou cosmétique ou pharmaceutique/médical . The invention makes it possible to improve the storage conditions of the consumable product by ensuring better asepsis of the base and the plug. The invention can be used for the packaging of dough or a liquid food or cosmetic or pharmaceutical / medical.
