Abstract

The box forming a container comprises a body forming a flange at a distance of the upper edge. A lid encases the body of the box and has a flange which is soldered typically through ultra-sounds, the soldered area extending not exactly up to breakage grooves.

Description

La présente invention concerne une nouvelle boîte pour contenir des produits divers qui doivent être conservés d'une manière étanche à l'air pendant un laps de temps plus ou moins long et qui doit être inviolable jusqu'au moment de l'utilisation du produit contenu.The present invention relates to a new box for containing various products which must be kept in an airtight manner for a more or less long period of time and which must be inviolable until the time of use of the product contained. .

L'invention s'étend en particulier à la réalisation de boîtes pouvant contenir des produits devant être conservés longuement, boîtes qui étaient jusqu'à présent fabriquées en métal.The invention extends in particular to the production of boxes which can contain products which must be kept for a long time, boxes which have hitherto been made of metal.

La technique antérieure a fait connaître de très nombreux modes de réalisation de boîtes qui comportent un corps recouvert par un couvercle fixé, soit par soudure, soit par sertissage, soit par une combinaison de ces deux moyens, des zones de moindre résistance étant prévues soit à la partie supérieure de la boîte soit dans le couvercle pour permettre de déchirer la boîte ou le couvercle et d'avoir ainsi accès au produit contenu.The prior art has made known numerous embodiments of boxes which comprise a body covered by a fixed cover, either by welding, or by crimping, or by a combination of these two means, zones of least resistance being provided either the upper part of the box is in the cover to allow the box or the cover to be torn and thus to have access to the product contained.

Le brevet des Etats-Unis 2 941 660 concerne un récipient présentant un couvercle pouvant être soudé de façon étanche après une opération de remplissage et il est conçu pour être facilement séparé du récipient par l'utilisateur tout en permettant une mise en place nouvelle ultérieure sur le récipient. Le récipient est, de préférence, réalisé en matière thermoplastique.U.S. Patent 2,941,660 relates to a container having a lid which can be sealed with a seal after a filling operation and is designed to be easily separated from the container by the user while allowing subsequent subsequent placement on the recipient. The container is preferably made of thermoplastic material.

Le brevet français 78 32472 concerne un récipient en matière plastique muni d'un couvercle également en matière plastique et ce couvercle est soudé sur le récipient, de préférence par vibrations, notamment des vibrations ultrasoniques. Une partie de rupture est prévue de préférence dans le récipient près de sa partie supérieure. La déchirure de la partie de rupture a pour effet de munir le couvercle d'une partie en forme d'anneau qui peut être emboîtée sur la partie restante du récipient et ainsi constituer un couvercle amovible.French patent 78 32472 relates to a plastic container provided with a cover also made of plastic and this cover is welded to the container, preferably by vibrations, in particular ultrasonic vibrations. A rupture part is preferably provided in the container near its upper part. The tearing of the breaking part has the effect of providing the cover with a ring-shaped part which can be fitted onto the remaining part of the container and thus constitute a removable cover.

Le brevet des Etats-Unis 3 463 347 décrit une fermeture pour un récipient, cette fermeture comprenant un organe venant s'appliquer sur une bride du récipient. La fermeture elle-même comporte des couteaux qui peuvent être déplacés dans une rainure au moyen d'une barre transversale.US Patent 3,463,347 describes a closure for a container, this closure comprising a member which is applied to a flange of the container. The closure itself has knives which can be moved in a groove by means of a cross bar.

Le brevet français 1 335 350 décrit un récipient présentant une ouverture en forme de gorge à sa partie supérieure,cette ouverture contenant une lame annulaire destinée à couper un couvercle qui est relié par soudure au-dessus du récipient.French patent 1 335 350 describes a container having a groove-shaped opening at its upper part, this opening containing an annular blade intended to cut a cover which is connected by welding above the container.

Le brevet français 1 511 724 concerne aussi un récipient en matière plastique dont une partie de la paroi latérale est souple, ce récipient étant, en outre, muni de soufflets ou autre parties déformables pour compenser les différences de température.French patent 1,511,724 also relates to a plastic container, one part of the side wall of which is flexible, this container being, moreover, provided with bellows or other deformable parts to compensate for temperature differences.

La présente invention crée une nouvelle boîte de très faible prix de revient, qui peut être stérilisée et remplie sous vide et dont l'ouverture est ensuite facile, sans nécessiter aucun outillage, sans que l'utilisateur puisse se blesser, la boîte présentant en outre l'avantage de pouvoir ensuite être réutilisée.The present invention creates a new box of very low cost price, which can be sterilized and filled under vacuum and whose opening is then easy, without requiring any tools, without the user being able to injure himself, the box also having the advantage that it can then be reused.

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, est caractérisée en ce qu'elle comporte un corps formant une bride et un couvercle prenant appui sur ladite bride et soudée à celle-ci sur une largeur inférieure à la largeur de la bride qui comporte des moyens de rupture, au moins de la partie contenant la soudure.According to the invention, the box forming a container for various products, in particular for food products, is characterized in that it comprises a body forming a flange and a cover bearing on said flange and welded thereto over a smaller width. the width of the flange which comprises breaking means, at least of the part containing the weld.

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.

La fig. 1 illustre de façon schématique un mode de réalisation d'une boîte selon l'invention, cette boîte comportant un corps 1 formant un fond 2 de préférence ondulé à partir duquel fait saillie une paroi latérale montante 3, la paroi 3 formant, extérieurement et à distance de son bord supérieur 3a, une bride périphérique 4. Le segment 5, qui s'étend depuis le bord supérieur 3a jusqu'au-dessus de la bride 4, sert au guidage du bord tombé 6 d'un couvercle 7 dont le dessus est aussi de préférence ondulé. Le bord tombé 6 du couvercle délimite, à sa partie basse, une bride 8 qui correspond à la bride 4 du corps.Fig. 1 schematically illustrates an embodiment of a box according to the invention, this box comprising a body 1 forming a bottom 2 preferably corrugated from which protrudes a rising side wall 3, the wall 3 forming, externally and at distance from its upper edge 3a, a peripheral flange 4. The segment 5, which extends from the upper edge 3a to above the flange 4, serves to guide the fallen edge 6 of a cover 7, the top of which is also preferably wavy. The dropped edge 6 of the cover delimits, at its lower part, a flange 8 which corresponds to the flange 4 of the body.

Tant le corps 1 que le couvercle 7 sont fabriqués en une matière soudable et choisie de préférence parmi celles pouvant supporter une température de stérilisation, c'est-à-dire au moins 105°C et de préférence voisine de 130°C. Un grand nombre de matières, notamment de matières plastiques, peuvent être utilisées pour remplir les conditions ci-dessus et parmi ces matières le polypropylène, dit stérilisable, semble particulièrement avantageux,car il permet une fabrication simple par moulage et il présente des qualités appréciées pour la réalisation de conteneurs de produits alimentaires.Both the body 1 and the cover 7 are made of a weldable material and preferably chosen from those capable of withstanding a sterilization temperature, that is to say at least 105 ° C. and preferably close to 130 ° C. A large number of materials, in particular plastics, can be used to fulfill the above conditions and among these materials polypropylene, said to be sterilizable, seems particularly advantageous, because it allows a simple manufacture by molding and it has qualities appreciated for the creation of food product containers.

Comme le montre la fig. 2, les brides 4 et 8 présentent des rainures 9, 9a formées sur tout ou partie de leur périphérie, ces rainures constituant des amorces de rupture.As shown in fig. 2, the flanges 4 and 8 have grooves 9, 9a formed over all or part of their periphery, these grooves constituting incipient fractures.

Les brides présentent aussi au moins une languette 10 saillant à proximité des amorces de rupture 11 pour permettre de déchirer les brides 4, 8 le long du fond des rainures 9, 9a.The flanges also have at least one tab 10 protruding near the breaking points 11 to allow the flanges 4, 8 to be torn along the bottom of the grooves 9, 9a.

Lorsque la boîte décrite ci-dessus est remplie, les brides 4 et 8 sont soudées ensemble le long d'une zone de soudage 12 qui s'étend sur toute la périphérie desdites brides sans toutefois atteindre une ligne passant par le fond des rainures 9, 9a. La soudure 12 assure une fixation étanche du couvercle sur le corps. Cette soudure est avantageusement réalisée par ultra-sons au moyen de sonotrodes lorsque la boîte est fabriquée en matière plastique, comme expliqué dans ce qui précède. Dans le cas d'une boîte métallique, elle pourrait être réalisée par tous moyens connus de la technique ou, éventuellement, par une colle appropriée.When the box described above is filled, the flanges 4 and 8 are welded together along a welding zone 12 which extends over the entire periphery of said flanges without however reaching a line passing through the bottom of the grooves 9, 9a. The weld 12 ensures a tight fixing of the cover on the body. This welding is advantageously carried out by ultrasound using sonotrodes when the box is made of plastic, as explained in the foregoing. In the case of a metal box, it could be produced by any means known in the art or, possibly, by an appropriate adhesive.

Lorsque le fond 2 de la boite et le couvercle 7 sont ondulés au moins partiellement, cela permet qu'ils soient déformés lorsque le remplissage de la boîte et sa fermeture sont exécutés sous vide. Il est remarquable de constater que lorsque la boîte est ouverte, c'est-à-dire après que les brides 4, 8 ont été déchirées comme expliqué, la boîte reste utilisable puisque le couvercle 6 peut être remis en place en l'enfilant sur le segment saillant 5. Ainsi un produit alimentaire contenu dans la boîte peut être protégé et conservé, soit à l'air libre, soit dans une atmosphère réfrigérée suivant sa nature.When the bottom 2 of the box and the cover 7 are at least partially corrugated, this allows them to be deformed when the filling of the box and its closing are carried out under vacuum. It is remarkable to note that when the box is open, that is to say after the flanges 4, 8 have been torn as explained, the box remains usable since the cover 6 can be replaced by threading it on the protruding segment 5. Thus a food product contained in the box can be protected and stored, either in the open air, or in a refrigerated atmosphere depending on its nature.

La fig. 4 montre que des boîtes réalisées comme décrites ci-dessus peuvent être prévues de façon à être gerbées les unes sur les autres. Dans ce cas la paroi latérale montante 3 du corps 1 présente, au moins, un bourrelet d'appui 14 saillant vers le bas et correspondant à une rainure annulaire 15 formée dans le couvercle 7.Fig. 4 shows that boxes produced as described above can be provided so as to be stacked on top of each other. In this case the rising side wall 3 of the body 1 has, at least, a support bead 14 projecting downward and corresponding to an annular groove 15 formed in the cover 7.

Les fig. 5 et 6 illustrent une légère variante selon laquelle le couvercle 7 est formé à partir du bord supérieur de la paroi latérale montante 3. Dans ce cas, le couvercle 7 est prévu pour présenter un bord montant 16 à sa périphérie. Une bride 8 est formée comme précédemment pour faire saillie à partir du bord montant 16 qui est emboîté dans le corps de boîte. La bride 8 délimite dans sa partie voisine du bord montant 16 un logement périphérique 17 dans lequel est disposé un fil 18, par exemple en acier, ce fil étant ancré par une de ses extrémités comme illustré en 19, soit dans la bride 8, soit sur le dessus du couvercle 7. L'extrémité libre du fil 18 est passée entre les parties en contact des brides 4 et 8 et est munie d'un organe de préhension 20. Les brides 4 et 8 sont ensuite soudées de préférence par ultra-sons, comme expliqué dans ce qui précède, ce mode de liaison ayant pour effet de noyer une partie au fil 18 dans la soudure 21 qui est réalisée de sorte que la liaison entre les brides est parfaitement étanche. Pour ouvrir la boîte, il suffit d'exercer une traction sur l'organe de préhension 20, le fil 18 assurant le cisaillage de la soudure 21.Figs. 5 and 6 illustrate a slight variant according to which the cover 7 is formed from the upper edge of the rising side wall 3. In this case, the cover 7 is provided to present a rising edge 16 at its periphery. A flange 8 is formed as above to protrude from the rising edge 16 which is fitted into the box body. The flange 8 delimits in its part near the rising edge 16 a peripheral housing 17 in which is disposed a wire 18, for example of steel, this wire being anchored by one of its ends as illustrated in 19, either in the flange 8, or on the top of the cover 7. The free end of the wire 18 is passed between the parts in contact with the flanges 4 and 8 and is provided with a gripping member 20. The flanges 4 and 8 are then preferably welded by ultra- sounds, as explained in the above, this mode of connection having the effect of drowning a part of the wire 18 in the weld 21 which is produced so that the connection between the flanges is perfectly sealed. To open the box, it suffices to pull the gripping member 20, the wire 18 ensuring the shearing of the weld 21.

La forme concave du couvercle 7, dans l'exemple de réalisation qui vient d'être décrit, permet de gerber facilement les boîtes, soit en prévoyant comme à la fig. 4 un décrochement périphérique 13 près du fond 2, soit en prévoyant que les parois latérales 3 soient en dépouille, c'est-à-dire que la boîte forme un tronc de cône ou un tronc de pyramide suivant qu'elle est de section circulaire ou polygonale.The concave shape of the cover 7, in the embodiment which has just been described, makes it possible to stack the boxes easily, either by providing as in FIG. 4 a peripheral recess 13 near the bottom 2, either by providing that the side walls 3 are undercut, that is to say that the box forms a truncated cone or a truncated pyramid depending on whether it is of circular section or polygonal.

Les fig. 7 à 9 illustrent une variante des moyens d'ouverture de la boîte qui peut être réalisée indifféremment, comme décrit en référence aux fig.l à 4 ou en référence à la fig. 6.Figs. 7 to 9 illustrate a variant of the means for opening the box which can be produced indifferently, as described with reference to FIGS. 1 to 4 or with reference to FIG. 6.

Dans cette réalisation, la soudure 21 est exécutée entre deux parties saillantes 4a et 8a des brides 4 et 8 et ces brides délimitent, à la périphérie de la soudure 21, un logement 22 fermé par des couronnes d'appui 23 et 24. Les couronnes 23 et 24 servent au maintien d'un anneau séparateur 25, par exemple constitué par un jonc de section rectangulaire qui forme des parties de coupe 26, par exemple au nombre de trois et décalées de 120° les unes par rapport aux autres.In this embodiment, the weld 21 is carried out between two projecting parts 4a and 8a of the flanges 4 and 8 and these flanges delimit, at the periphery of the weld 21, a housing 22 closed by support rings 23 and 24. The rings 23 and 24 are used to maintain a separating ring 25, for example constituted by a rod of rectangular section which forms cutting parts 26, for example three in number and offset by 120 ° relative to each other.

Des gâchettes 27 sont prévues en regard des parties de coupe 26 pour faire saillie à l'extérieur des brides 4 et 8. Pour ouvrir la boîte il suffit d'appliquer les doigts contre les trois gâchettes 27 afin de resserrer l'anneau séparateur 25 dont les parties de coupe 26 sectionnement la soudure 21. On fait effectuer ensuite à l'anneau séparateur une rotation de 120° pour que les parties de coupe 26 tranchent complètement la soudure 21.Triggers 27 are provided opposite the cutting parts 26 to project outside the flanges 4 and 8. To open the box, it suffices to apply the fingers against the three triggers 27 in order to tighten the separating ring 25, the cutting parts 26 of which cut the weld 21. The separating ring is then made to rotate by 120 ° so that the cutting parts 26 completely cut the weld 21.

Il est remarquable de constater que les modes de réalisation décrits, tant en référence aux fig. 5 et 6 qu'aux fig. 7 à 9 permettent, tout comme dans le mode de réalisation précédent des fig. 1 à 4, un usage continu de la boîte après son ouverture initiale.It is remarkable to note that the embodiments described, both with reference to FIGS. 5 and 6 as in fig. 7 to 9 allow, just as in the previous embodiment of FIGS. 1 to 4, continuous use of the box after its initial opening.

Aux fig. 10 à 14, le corps 1 de la boîte comporte une paroi montante 3 qui forme une bride périphérique 4. La boîte est munie d'un couvercle 7 délimitant aussi une bride 8 qui correspond à la bride 4 du corps.In fig. 10 to 14, the body 1 of the box has a rising wall 3 which forms a peripheral flange 4. The box is provided with a cover 7 also delimiting a flange 8 which corresponds to the flange 4 of the body.

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. Le bord des segments 29, 30 qui jouxtent la gorge 28 est à angle vif.The flange 4 has in its upper wall a peripheral groove 28 on either side of which two segments 29, 30 are delimited. 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 ci-dessus 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 above edges, 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 boîte 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. Lorsqu'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 boîte 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 exert a pressure on the button 34, which breaks the flange 8 at the level of the breaking primers 31, 32. By pulling on the button 34, the entire annular segment 33 is then torn. 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 in its entirety.

Les fig. 12 et 13 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. 12 and 13 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, pressure is exerted as before first of all 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.

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.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.
