Abstract

The can forming a container comprises a body 3 delimiting a flange 4 distant from the upper edge. A lid 7 fits over the body of the can and has a flange 8 which is welded, particularly by ultrasonic means at 35, the welding not extending completely up to fracture grooves 31, 32.

Description

La présente invention concerne des perfectionnements apportés à la boîte du brevet principal qui est destinée à contenir des produits divers devant être conservés à l'abri de l'air pendant un laps de temps plus ou moins long et qui doit permettre une stérilisation desdits produits. The present invention relates to improvements made to the box of the main patent which is intended to contain various products to be kept away from air for a more or less long period of time and which must allow sterilization of said products.

Selon le brevet principal, la boite comporte un corps sur lequel est monté un couvercle et des brides formées respectivement par le corps et le couvercle sont soudées entre elles sur une partie de leur largeur, des moyens de rupture étant prévus pour permettre de déchirer la partie soudée des brides. According to the main patent, the box comprises a body on which a cover is mounted and flanges formed respectively by the body and the cover are welded together over part of their width, rupture means being provided to allow the part to be torn welded flanges.

Les boites auxquelles se réfère l'invention étant fabriquées en matière synthétique, la soudure est le plus souvent réalisée par vibration, c'est- -dire notamment par application d'ultra-sons au moyen de sonotrodes qui exercent une pression sur les parties des brides à souder. I1 est apparu que la soudure est souvent effectuée sur une largeur plus importante.que celle désirée ce qui conduit à des difficultés d'ouverture ou bien à un risque de-défaut dans la soudure si la largeur de celle-ci est trop limitée. The boxes to which the invention refers being made of synthetic material, welding is most often carried out by vibration, that is to say in particular by application of ultrasound by means of sonotrodes which exert pressure on the parts of the welding flanges. It has become apparent that the welding is often carried out over a greater width than that desired, which leads to opening difficulties or else to a risk of defect in the welding if the width of the latter is too limited.

La présente invention apporte des perfectionnements qui éliminent le risque de former une soudure trop large ou trop étroite et, de plus, l'ouverture de la boîte est rendue extrêmement facile. The present invention provides improvements which eliminate the risk of forming a weld that is too wide or too narrow and, moreover, the opening of the box is made extremely easy.

Conformément à l'invention, la boîte formant conteneur pour produits divers,notamment pour produits alimentaires, cette boîte comportant un corps formant une bride et un couvercle prenant appui sur ladite bride et soudé à celleci sur une largeur inférieure à la largeur de la bride qui comporte des moyens de rupture au moins de la partie contenant la soudure conformément à la revendication 1 du brevet principal est caractériséeen ce que la soudure est formée à la périphérie externe d'une gorge prévue dans l'une des brides de la boîte ou couvercle.  According to the invention, the box forming a container for various products, in particular for food products, this box comprising a body forming a flange and a cover bearing on said flange and welded to it over a width less than the width of the flange which comprises means for breaking at least the part containing the weld according to claim 1 of the main patent is characterized in that the weld is formed at the external periphery of a groove provided in one of the flanges of the box or cover.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics of the invention will also emerge from the detailed description which follows.

Des formes de réalisation de l'objet de l'invention sont représentées, à titre d'exemples non limitatifs, aux dessins annexés. Embodiments of the object of the invention are shown, by way of nonlimiting examples, in the accompanying drawings.

La fig. 1 est une coupe partielle schématique d'une botte selon l'invention. Fig. 1 is a schematic partial section of a boot according to the invention.

La fig. 2 est un plan vu de dessus correspondant à la fig. 1 mais à plus petite échelle. Fig. 2 is a plan seen from above corresponding to FIG. 1 but on a smaller scale.

La fig. 3 est une coupe partielle analogue à la fig. 1 d'une variante. Fig. 3 is a partial section similar to FIG. 1 of a variant.

La fig. 4 est une coupe vue suivant la ligne IV-Iv de la fig. 3. Fig. 4 is a section seen along the line IV-Iv of FIG. 3.

Comme au brevet principal, le corps 1 de la botte comporte une paroi montante 3 qui forme une bride périphérique 4. La botte est munie d'un couvercle 7 délimitant aussi une bride 8 qui correspond à la bride 4 du corps. As in the main patent, the body 1 of the boot has a rising wall 3 which forms a peripheral flange 4. The boot is provided with a cover 7 also delimiting a flange 8 which corresponds to the flange 4 of the body.

Suivant l'addition, la bride 4 présente dans sa paroi supérieure une gorge périphérique 28 de part et d'autre de laquelle sont délimités deux segments 29, 30. Depending on the addition, the flange 4 has in its upper wall a peripheral groove 28 on either side of which two segments 29, 30 are delimited.

Le bord des segments 29, 30 qui jouxtent la gorge 28 est à angle vif.The edge of the segments 29, 30 which adjoin the groove 28 is at a sharp angle.

La bride 8 présente en regard des bords cidessus des amorces de rupture périphériques 31, 32. De cette façon un segment annulaire 33 s'étend au-dessus de la gorge périphérique 28. Au moins un bouton 34 est prévu au-dessus du segment 33. The flange 8 has, opposite the edges above, peripheral breaking primers 31, 32. In this way an annular segment 33 extends above the peripheral groove 28. At least one button 34 is provided above the segment 33 .

Lorsque la boite est remplie et que le couvercle 7 est mis en place, il est procédé à la soudure du couvercle ce qui est réalisé, par exemple, par vibration. La soudure est formée à la périphérie des brides de manière que seule la partie de la bride 8 du couvercle s'étendant au delà de l'amorce de rupture 31 soit soudée sur le segment 30. La présence de la gorge périphérique 28 empêche que la soudure puisse s'étendre vers l'intérieur de sorte qu'un anneau soudé 35 de largeur bien uniforme est formé.Lors qu'on désire ouvrir la boîte il suffit d'exercer une pression sur le bouton 34 ce qui rompt la bride 8 au niveau des amorces de rupture 31, 32. En tirant sur le bouton 34 on déchire ensuite tout le segment annulaire 33 ce qui fait que le couvercle 7 peut être retiré facilement puis ensuite remis en place si le contenu de la boite n'est pas utilisé dans sa totalité. When the box is filled and the cover 7 is put in place, the cover is welded, which is achieved, for example, by vibration. The weld is formed at the periphery of the flanges so that only the part of the flange 8 of the cover extending beyond the rupture initiator 31 is welded to the segment 30. The presence of the peripheral groove 28 prevents the solder can extend inward so that a welded ring 35 of uniform width is formed. When it is desired to open the box, it suffices to press the button 34 which breaks the flange 8 at level of the breaking primers 31, 32. By pulling on the button 34, the entire annular segment 33 is then torn apart, which means that the cover 7 can be easily removed and then put back in place if the contents of the box are not used as a whole.

Les fig. 3 et 4 illustrent une légère variante selon laquelle le bouton 34a est formé à l'extrémité d'une patte 36 faisant elle-même partie du segment annulaire 33. Dans cette réalisation, pour ouvrir, on exerce comme précédemment tout d'abord une pression sur le bouton 34a pour rompre le segment annulaire 33 et ensuite on exerce une traction pour déchirer ledit segment 33. La présence de la patte 36 qui est souple facilite la déchirure du segment 33. Figs. 3 and 4 illustrate a slight variant according to which the button 34a is formed at the end of a tab 36 which itself forms part of the annular segment 33. In this embodiment, first of all, pressure is exerted as before on the button 34a to break the annular segment 33 and then a pull is applied to tear said segment 33. The presence of the tab 36 which is flexible facilitates the tearing of the segment 33.

L'invention n'est pas limitée aux exemples de réalisation représentés et décrits en détail car diverses modifications peuvent y être apportées sans sortir de son cadre. The invention is not limited to the embodiments shown and described in detail since various modifications can be made thereto without departing from its scope.

En particulier, la gorge périphérique 28 peut être formée dans la bride du couvercle et, dans ce cas, l'anneau ou segment annulaire de rupture 33 est formé dans la bride de la boîte.  In particular, the peripheral groove 28 can be formed in the flange of the cover and, in this case, the annular annulus or segment 33 is formed in the flange of the box.
