Definitions
- the present invention relates to a closure cover for a shaped jar.
- substantially cylindrical comprising a bottom and a skirt at the periphery of said bottom and perpendicular to it, the inner part of the skirt comprising a thread intended to cooperate with the external thread of the jar.
- jar closure systems substantially cylindrical shape, in which it is provided inside the cover 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 jar closings.
- the jar is closed with an aluminum seal which is welded to the opening of said jar.
- first opening we tear off this seal and we must therefore guarantee the seal secondary.
- the problem with the current solution is that on the one hand the cushion is expensive and on the other hand, there has to be an extra step to combine it with the seal before removal inside the cover.
- the object of the present invention is to develop a cover in a single part and which would however guarantee a secondary seal equivalent to that obtained with the cushion with a sealing system with aluminum jar.

Abstract
Description
La présente invention concerne un couvercle de fermeture pour bocal de forme sensiblement cylindrique, 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 bocal.The present invention relates to a closure cover for a shaped jar. substantially cylindrical, comprising a bottom and a skirt at the periphery of said bottom and perpendicular to it, the inner part of the skirt comprising a thread intended to cooperate with the external thread of the jar.
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 soudé sur l'ouverture dudit bocal. Lors de la première ouverture, on arrache 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.So far on the market, there are jar closure systems substantially cylindrical shape, in which it is provided inside the cover 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 jar closings. In this type of packaging, the jar is closed with an aluminum seal which is welded to the opening of said jar. When first opening, we tear off this seal and we must therefore guarantee the seal secondary. The problem with the current solution is that on the one hand the cushion is expensive and on the other hand, there has to be an extra step to combine it with the seal before removal inside the cover.
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.The object of the present invention is to develop a cover in a single part and which would however guarantee a secondary seal equivalent to that obtained with the cushion with a sealing system with aluminum jar.
La présente invention concerne un couvercle de fermeture selon le préambule de la revendication 1, dans lequel l'intérieur du fond du couvercle 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 supérieur du bocal.The present invention relates to a closure cover according to the preamble of claim 1, wherein the interior of the bottom of the cover comprises near the skirt a system of three concentric lips, namely lip inner, middle lip and outer lip, designed to rest on the rim top of the jar.
Le couvercle selon l'invention convient particulièrement bien pour les bocaux comportant un operculage en aluminium , le scellage dudit opercule sur le bord supérieur dudit bocal ayant été fait par induction. En effet, ce scellage par induction se fait avec le contenu et avec le couvercle déjà mis en place. La présence des trois lèvres concentriques précitées permet en tout cas deux fonctionnalités : les lèvres intérieure et extérieure garantissent un bon positionnement de l'opercule au moment du scellage et la lèvre médiane garantit après la première ouverture une bonne étanchéité secondaire.The lid according to the invention is particularly suitable for jars comprising an aluminum seal, the sealing of said seal on the edge upper of said jar having been made by induction. Indeed, this sealing by induction is done with the contents and with the lid already in place. The presence of the above three concentric lips in any case allows two features: the inner and outer lips guarantee a good positioning of the seal at the time of sealing and the middle lip guarantees after the first opening a good secondary seal.
Au moment du scellage par induction tout élément en contact avec l'opercule 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.At the time of induction sealing, any element in contact with the seal will undergo a temperature rise: the outer and inner lips will undergo this warming up. However, with regard to the middle lip, it should not be undergoes said heating, because it could melt and no longer fill at the time from the first opening its secondary sealing functionality. To achieve this result, a middle lip is provided having a height less than both other lips.
Le couvercle 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.The cover according to the invention is particularly suitable for plugging 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 entre entre 0,5 et 1,5 mm.As the functionality of both inner and outer lips is good keep the seal in place, these two lips are normally arranged at a distance which corresponds substantially to the thickness of the jar on which is placed said cover. This distance is normally between 1 and 4mm. Regarding the height of these same lips, it is between 0.5 and 1.5 mm.
Dans une autre forme de réalisation du couvercle selon l'invention, il est prévu 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 1,2 0,8 et 0,6 mm.In another embodiment of the cover according to the invention, there are provided decreasing lip heights, from the outer lip to the lip median. For example, we can consider an embodiment with lips exterior, interior and median respectively 1.2 0.8 and 0.6 mm in height.
La suite de la description est faite en référence aux dessins sur lesquels
Le couvercle (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 bocal contenant le produit à conserver. Le couvercle est normalement en matière plastique, comme du polyéthylène haute densité ou du polypropylène. Le couvercle 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 cover (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 jar containing the product to be stored. The cover is normally made of material plastic, such as high density polyethylene or polypropylene. The cover is preferably in the latter material. We can see on the figure that part A comprising the three concentric lips is located on the face inside the bottom and close to the skirt.
La figure 2 montre bien le système de trois lèvres. La lèvre extérieure (5) a une hauteur plus élevée que la lèvre intérieure (6). La lèvre médiane (11) est celle qui a la dimension la plus faible.Figure 2 clearly shows the three-lip system. The outer lip (5) has a higher than the inner lip (6). The middle lip (11) is the one that has the lowest dimension.
La figure 3 montre le couvercle (1) disposé pour la fermeture du bocal (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 bocal. Après délaminage de l'opercule (non représenté), c'est la lèvre médiane (11) qui garantit pleinement l'étanchéité de la fermeture.Figure 3 shows the cover (1) arranged for closing the jar (7). We sees very well that the outer (5) and inner (6) lips rest respectively on the outer (8) and inner (9) parts of the rim (10) of the jar. After delamination of the cover (not shown), it is the middle lip (11) which guarantees fully sealing 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.The shape of the lips is not critical. We can very well consider them, seen in section, triangular in shape as in Figure 2. But it is also possible to have them in the form of tabs as in Figure 3.
