Description

Récipient avec sa fermeture.Container with its closure.
La présente invention concerne un récipient avec sa fermeture, ledit récipient étant de forme sensiblement cylindrique et comportant un col avec un rebord sur lequel est soudé une membrane et ladite fermeture comprenant un fond et une jupe à la périphérie dudit fond et perpendiculairement à celui-ci, la partie intérieure de la jupe comportant un filetage prévu pour coopérer avec le filet extérieur du récipient.The present invention relates to a container with its closure, said container being of substantially cylindrical shape and comprising a neck with a rim on which a membrane is welded and said closure comprising a bottom and a skirt at the periphery of said bottom and perpendicular thereto. , the inner part of the skirt comprising a thread intended to cooperate with the outer thread of the container.
Jusqu'à présent sur le marché, il existe des systèmes de fermeture de bocal de forme sensiblement cylindrique, dans lesquels il est prévu à l'intérieur du couvercle un coussin. L'intérêt d'avoir ce coussin est qu'il permet après la première ouverture de garantir une étanchéité secondaire, c'est-à-dire l' étanchéité lors des refermetures du bocal. Dans ce type de conditionnement, le bocal est fermé avec un opercule en aluminium qui est scellé par induction sur l'ouverture dudit bocal.Hitherto on the market, there are closure systems of jar of substantially cylindrical shape, in which there is provided inside the lid a cushion. The advantage of having this cushion is that it allows after the first opening to guarantee a secondary seal, that is to say the seal during reclosings of the jar. In this type of packaging, the jar is closed with an aluminum seal which is sealed by induction on the opening of said jar.
Lors de la première ouverture , on arrache complètement cet opercule et il faut donc garantir l'étanchéité secondaire. Le problème avec la solution actuelle est que d'une part le coussin est cher et d'autre part, il faut prévoir une étape supplémentaire pour le combiner avec l'opercule avant la dépose à l'intérieur du couvercle.During the first opening, this cover is completely torn off and it is therefore necessary to guarantee the secondary seal. The problem with the current solution is that on the one hand the cushion is expensive and on the other hand, it is necessary to envisage an additional stage to combine it with the cover before the deposit inside the cover.
Le brevet US 4'531'649 concerne un système de fermeture de bocal, dans lequel on fait un scellage par induction d'une membrane composite sur le rebord du bocal et on dispose d'une fermeture comportant un système de trois lèvres concentriques. Dans cette solution, il n'y a aucune spécificité sur la dimension desdites lèvres, ce qui conduit à un risque de fusion desdites lèvres lors du scellage, qui peuvent ensuite ne plus remplir leur rôle d'étanchéité secondaire. Le modèle d'utilité GM 8133968 consiste aussi en un système de fermeture à trois lèvres et dans ce cas aussi, on a un risque de fusion desdites lèvres au moment du scellage par induction.US Patent 4,531,649 relates to a jar closure system, in which an induction seal is made of a composite membrane on the rim of the jar and there is a closure comprising a system of three concentric lips. In this solution, there is no specificity on the dimension of said lips, which leads to a risk of fusion of said lips during sealing, which can then no longer fulfill their secondary sealing role. The utility model GM 8133968 also consists of a three-lip closure system and in this case too, there is a risk of fusion of said lips at the time of induction sealing.
Le but de la présente invention est de mettre au point un couvercle en une seule pièce et qui cependant permettrait de garantir une étanchéité secondaire équivalente à celle obtenue avec le coussin avec un système d'operculage avec aluminium du bocal. La présente invention concerne un récipient avec sa fermeture, ledit récipient étant de forme sensiblement cylindrique et comportant un col avec un rebord sur lequel est soudé une membrane et ladite fermeture comprenant un fond et une jupe à la périphérie dudit fond et perpendiculairement à celui-ci, la partie intérieure de la jupe comportant un filetage prévu pour coopérer avec le filet extérieur du récipient , dans lequel la membrane est soudée par induction sur le rebord du récipient et l'intérieur du fond de la fermeture comporte à proximité de la jupe un système de trois lèvres concentriques, à savoir lèvre intérieure, lèvre médiane et lèvre extérieure, prévues pour s'appuyer sur le rebord du récipient, la lèvre extérieure a une hauteur x supérieure à la hauteur y de la lèvre intérieure et la lèvre médiane une hauteur z inférieure à celle de la lèvre intérieure, la distance qui sépare la lèvre intérieure de la lèvre extérieure correspond sensiblement à l'épaisseur du récipient sur lequel est disposé ladite fermeture.The purpose of the present invention is to develop a cover in one piece and which however would guarantee a secondary seal equivalent to that obtained with the cushion with a sealing system with aluminum of the jar. The present invention relates to a container with its closure, said container being of substantially cylindrical shape and comprising a neck with a rim on which a membrane is welded and said closure comprising a bottom and a skirt at the periphery of said bottom and perpendicular thereto. , the inner part of the skirt comprising a thread intended to cooperate with the external thread of the container, in which the membrane is welded by induction on the rim of the container and the interior of the bottom of the closure comprises near the skirt a system of three concentric lips, namely inner lip, middle lip and outer lip, intended to rest on the rim of the container, the outer lip has a height x greater than the height y of the inner lip and the middle lip a height z less than that of the inner lip, the distance between the inner lip and the corresponding outer lip It is substantially the thickness of the container on which said closure is placed.
La fermeture selon l'invention convient particulièrement bien pour les récipients comportant une membrane qui est une feuille en aluminium , le scellage de ladite membrane sur le bord supérieur dudit récipient ayant été fait par induction. En effet, ce scellage par induction se fait avec le contenu et avec la fermeture et la membrane déjà mis en place. La présence des trois lèvres concentriques précitées ayant des hauteurs différentes permet en tout cas trois fonctionnalités : le lèvre extérieure garantit un bon positionnement de la membrane avant que la lèvre intérieure ne plaque la membrane en la déformant partiellement autour du rebord du récipient au moment du scellage par induction et la lèvre médiane garantit après la première ouverture une bonne étanchéité secondaire. Comme la lèvre médiane est la plus courte des trois, on garantit totalement ladite étanchéité secondaire.The closure according to the invention is particularly suitable for containers comprising a membrane which is an aluminum sheet, the sealing of said membrane on the upper edge of said container having been done by induction. Indeed, this induction sealing is done with the content and with the closure and the membrane already in place. The presence of the three aforementioned concentric lips having different heights allows in any case three functions: the outer lip guarantees a good positioning of the membrane before the inner lip does not plate the membrane by partially deforming it around the rim of the container at the time of sealing by induction and the middle lip guarantees a good secondary seal after the first opening. As the middle lip is the shortest of the three, said secondary seal is completely guaranteed.
Au moment du scellage par induction , tout élément en contact avec la membrane va subir une montée en température : les lèvres extérieure et intérieure subiront cet échauffement. Par contre , s'agissant de la lèvre médiane, il ne faut pas qu'elle subisse ledit échauffement, car elle pourrait fondre et ne plus remplir au moment de la première ouverture sa fonctionnalité d'étanchéité secondaire. Pour parvenir à ce résultat, on prévoit une lèvre médiane ayant une hauteur inférieure aux deux autres lèvres, c'est-à-dire une lèvre qui ne touche pas le rebord du col du récipient. La fermeture selon l'invention convient particulièrement bien pour le bouchage de bocaux en verre ou en plastique contenant des produits en poudre, comme de la poudre de cacao ou de la poudre de café instantané.At the time of the induction sealing, any element in contact with the membrane will undergo a rise in temperature: the outer and inner lips will undergo this heating. On the other hand, as regards the middle lip, it must not undergo said heating, because it could melt and no longer fill its secondary sealing functionality at the time of the first opening. To achieve this result, there is provided a middle lip having a height less than the other two lips, that is to say a lip which does not touch the rim of the neck of the container. The closure according to the invention is particularly suitable for closing glass or plastic jars containing powdered products, such as cocoa powder or instant coffee powder.
Comme la fonctionnalité des deux lèvres intérieure et extérieure est de bien maintenir en place l'opercule, ces deux lèvres sont normalement disposées à une distance qui correspond sensiblement à l'épaisseur du bocal sur lequel est disposé ledit couvercle. Cette distance est normalement comprise entre 1 et 4mm. S'agissant de la hauteur de ces mêmes lèvres, elle est comprise pour la hauteur x entre 4/10 mm et 4 mm, pour la hauteur y entre 1/10 mm et 3 mm et pour la hauteur z entre 5/100 mm et 1,8 mm.As the functionality of the two inner and outer lips is to keep the cover in place, these two lips are normally arranged at a distance which corresponds substantially to the thickness of the jar on which said cover is placed. This distance is normally between 1 and 4mm. As regards the height of these same lips, it is included for the height x between 4/10 mm and 4 mm, for the height y between 1/10 mm and 3 mm and for the height z between 5/100 mm and 1.8 mm.
Il est prévu selon l'invention des hauteurs de lèvres décroissantes, depuis la lèvre extérieure jusqu'à la lèvre médiane. Par exemple, on peut envisager un mode de réalisation avec des lèvres extérieure, intérieure et médiane respectivement de hauteur 1,5 , 0,8 et 0,6 mm .According to the invention, decreasing lip heights are provided, from the outer lip to the middle lip. For example, an embodiment can be envisaged with outer, inner and middle lips of 1.5, 0.8 and 0.6 mm height respectively.
La suite de la description est faite en référence aux dessins sur lesquelsThe following description is made with reference to the drawings on which
Figure 1 est une coupe schématique du couvercle selon l'invention,FIG. 1 is a schematic section of the cover according to the invention,
Figure 2 est un agrandissement de A de la figure 1 et Figure 3 est une représentation schématique du couvercle disposé sur un bocal.Figure 2 is an enlargement of A of Figure 1 and Figure 3 is a schematic representation of the lid disposed on a jar.
La fermeture (1) comprend un fond (2) et une jupe latérale (3). L'intérieur de la jupe comprend un filetage (4) pour accrocher sur le filet correspondant du récipient contenant le produit à conserver. La fermeture est normalement en matière plastique, comme du polyéthylène haute densité ou du polypropylène. La fermeturee est de préférence dans cette dernière matière. On voit bien sur la figure que la partie A comportant les trois lèvres concentriques est située sur la face intérieure du fond et proche de la jupe.The closure (1) comprises a bottom (2) and a side skirt (3). The interior of the skirt includes a thread (4) for hanging on the corresponding net of the container containing the product to be preserved. The closure is normally made of plastic, such as high density polyethylene or polypropylene. The closure is preferably in the latter material. We can clearly see in the figure that part A comprising the three concentric lips is located on the inner face of the bottom and close to the skirt.
La figure 2 montre bien le système de trois lèvres. La lèvre extérieure (5) a une hauteur x plus élevée que la hauteur y de la lèvre intérieure (6). La lèvre médiane (11) est celle qui a la dimension z la plus faible. La figure 3 montre la fermeture (1) disposée pour la fermeture du récipient (7). On voit très bien que les lèvres extérieure (5) et intérieure (6) reposent respectivement sur les parties extérieure (8) et intérieure (9) du rebord (10) du col (13) du récipient. Après délaminage de la membrane (12), c'est la lèvre médiane ( 11) qui garantit pleinement l'étanchéité de la fermeture.Figure 2 clearly shows the three-lip system. The outer lip (5) has a height x greater than the height y of the inner lip (6). The middle lip (11) is the one with the smallest dimension z. Figure 3 shows the closure (1) arranged for closing the container (7). We can clearly see that the outer (5) and inner (6) lips rest respectively on the outer (8) and inner (9) parts of the rim (10) of the neck (13) of the container. After delamination of the membrane (12), it is the middle lip (11) which fully guarantees the sealing of the closure.
La forme des lèvres n'est pas critique. On peut très bien les envisager, vu en coupe, de forme triangulaire comme sur la figure 2. Mais il est aussi possible de les avoir sous forme de languettes , comme sur la figure 3. La seule obligation est que la lèvre médiane ne touche pas, au moment du scellage, le rebord (10) du récipient. The shape of the lips is not critical. We can very well consider them, seen in section, of triangular shape as in Figure 2. But it is also possible to have them in the form of tongues, as in Figure 3. The only requirement is that the middle lip does not touch , at the time of sealing, the rim (10) of the container.
