Abstract
Can closure system, which allows them to be stoppered (re-closed) after opening. Cans, tins of beer, water, lemonade, etc. are opened by a lever arm crimped onto a cylindrical deformation of the lid. By lifting it, pressure is applied to a pre-cut area and a hole is thereby opened - the cut-out tab remains fastened by one edge to the lid, by a small unpre-cut part. Nothing is provided that can cover or block this hole. Often, the drinks are drunk in several stages, straight from the can. The drinks contained may attract wasps and bees, which, once inside, are invisible. There is therefore a risk of accident. The invention consists in giving to the lever arm the shape of the hole opening, in order to be able to cover it and/or to adjust to it and to do this, after a 180 degree rotation in the horizontal plane (lid plane). The rotation is carried out around the lever attachment point (crimping point on a cylindrical deformation on the lid). With a very small extra cost, modifying the shape of the existing opening lever and using a movement of...

DESCRIPTION Système de fermeture des canettes, qui permet d'obturer (refermer) ces dernières après ouverture.
L'invention se rapporte aux canettes, boîtes, contenants cylindriques en métal, contenant de la bière, des limonades, des eaux.... et permet de les obturer temporairement pendant leur utilisation.
Etat des techniques Le système le plus fréquent d'ouverture des canettes est bien connu (fig. 1)- (fig. 2).
L'ouverture est prédécoupée, tracée sur le couvercle (pièce supérieure de la canette).
Un levier (fig. 2) prenant appui et serti sur une déformation cylindrique du couvercle (fig. 1 c) (fig. 2c) permet de détacher la languette prédécoupée (fig. 2g) en appuyant dessus. Pour ce faire, on lève (fig. 1 la partie du levier opposée au trou prédécoupé (fig. 2a) par rapport au point de sertissage (fig. 1 c) (fig. 2c).
La languette n'est pas totalement prédécoupée, ce qui lui permet de rester accrochée au couvercle.
Problème existant.
Le trou (fig. 1 a) ouvert dans la canette par ce procédé ne peut pas être fermé. Les boissons contenues attirent de nombreux insectes tels que abeilles, guêpes, frelons,... Ces derniers peuvent s'introduire par l'ouverture, le trou de la canette (de la boîte) et sont alors invisibles.
Souvent des boissons sont bues directement à même) la canette en plusieurs épisodes.
Toute personne portant à la bouche une canette dans laquelle se serait introduit une abeille, ou une guêpe ou un frelon... risque un accident grave-voire même la mort.
L'invention concerne la pièce servant de bras de levier, sertie sur une déformation du couvercle (fig. 2a), (fig. 3d), (fig. 4), (fig. 4d).
Elle consiste à donner à la partie de cette pièce opposée à l'ouverture et devant être
EMI1.1
soulevée (fig. 3d) (fig. 4d), la même forme que l'ouverture, le trou, la découpe (fig. la) symétrique à cette dernière par rapport au point de rotation (fig. 3c) (point de sertissage de la pièce).
Une rotation de 1800 dans un plan horizontal (fig. 3b) (le plan de la partie supérieure de la boîte), permettra alors à la partie bras de levier (fig. 3d), (fig. 4d) de couvrir, d'obturer, le trou (l'ouverture) de la canette et si nécessaire d'y être légèrement sertie.
Mis aux formes actuelles des trous et ouvertures des canettes, le bras de levier (fig.
3d) (fig. 4d) sera légèrement plus grand que celui existant actuellement (fig. 2a) ; L'espace entre l'extrémité du bras de levier et le bord de la canette (fig. 3f) sera plus petit qu'actuellement (fig. 1 e), afin de pouvoir saisir aisément le bras de levier, il sera
<Desc/Clms Page number 2>
muni de deux petites ailettes latérales (fig. 4g) ou alors le dessin de la découpe devra être modifié.
Ces ailettes (fig. 4g) permettront également d'ôter le bras de levier (fig. 4d) quant après une rotation de 180 0, il aura servi à obturer la découpe en la couvrant ou en s'y emboîtant. L'épaisseur totale du bras de levier ne devrait pas dépasser la hauteur du rebord de la boîte (fig. 3h). Le bras de levier (fig. 4d) sera légèrement conique sur son épaisseur et sera muni d'une rainure, cannelure ou déformation (fig. 4h) permettant de le sertir légèrement sur le trou d'ouverture (fig. 3a) afin de l'y maintenir.
Un changement de la forme (fig. 1 h) de la légère défonce des couvercles permettra d'effectuer plus aisément la rotation (fig. 3e).
La découpe (fig. 4b), (fig. 2b) qui permet un levage aisé du bras de levier peut être ramenée à une simple fente dans sa partie qui après rotation couvrira le trou, ou si l'on désire une fermeture plus hermétique, la découpe sera légèrement modifiée ou la partie bras de levier-couvercle construite en repliant le métal vers le bas pour rejoindre le point de sertissage (fig. 3c) sous cette découpe (fig. 4b).

DESCRIPTION Cans closing system, which allows to close (close) them after opening.
The invention relates to cans, boxes, cylindrical metal containers, containing beer, lemonades, waters ... and allows to temporarily seal them during their use.
State of the techniques The most frequent system for opening cans is well known (fig. 1) - (fig. 2).
The opening is pre-cut, traced on the cover (upper part of the bobbin).
A lever (fig. 2) resting and crimped on a cylindrical deformation of the cover (fig. 1 c) (fig. 2c) makes it possible to detach the precut tab (fig. 2g) by pressing on it. To do this, lift (fig. 1 the part of the lever opposite the pre-cut hole (fig. 2a) relative to the crimp point (fig. 1 c) (fig. 2c).
The tongue is not completely pre-cut, which allows it to remain attached to the cover.
Existing problem.
The hole (fig. 1 a) opened in the bobbin by this process cannot be closed. The drinks contained attract many insects such as bees, wasps, hornets, ... These can be introduced through the opening, the hole in the can (of the box) and are then invisible.
Often drinks are drunk directly from the can in several episodes.
Anyone carrying in the mouth a can in which a bee, or a wasp or a hornet is introduced ... risks a serious accident - even death.
The invention relates to the part serving as a lever arm, set on a deformation of the cover (fig. 2a), (fig. 3d), (fig. 4), (fig. 4d).
It consists in giving to the part of this part opposite the opening and to be
EMI1.1
raised (fig. 3d) (fig. 4d), the same shape as the opening, the hole, the cutout (fig. la) symmetrical to the latter with respect to the point of rotation (fig. 3c) (crimping point of the room).
A rotation of 1800 in a horizontal plane (fig. 3b) (the plane of the upper part of the box), will then allow the lever arm part (fig. 3d), (fig. 4d) to cover, to shut off , the hole (opening) of the bobbin and if necessary be lightly crimped.
Put in the current shapes of the holes and openings of the cans, the lever arm (fig.
3d) (fig. 4d) will be slightly larger than the existing one (fig. 2a); The space between the end of the lever arm and the edge of the bobbin (fig. 3f) will be smaller than currently (fig. 1 e), in order to be able to easily grasp the lever arm, it will be
<Desc / Clms Page number 2>
provided with two small lateral fins (fig. 4g) or else the design of the cutout must be modified.
These fins (fig. 4g) will also make it possible to remove the lever arm (fig. 4d) as after a rotation of 180 0, it will have been used to close the cut by covering it or interlocking therewith. The total thickness of the lever arm should not exceed the height of the edge of the box (fig. 3h). The lever arm (fig. 4d) will be slightly conical over its thickness and will be provided with a groove, groove or deformation (fig. 4h) allowing it to be crimped slightly over the opening hole (fig. 3a) in order to 'keep it there.
A change in the shape (fig. 1 h) of the slight knocking of the covers will make it easier to rotate (fig. 3e).
The cutout (fig. 4b), (fig. 2b) which allows easy lifting of the lever arm can be reduced to a simple slit in its part which after rotation will cover the hole, or if a more hermetic closure is desired, the cut will be slightly modified or the lever arm-cover part constructed by folding the metal down to join the crimp point (fig. 3c) under this cut (fig. 4b).
