Abstract

Metallic package with a "peelable" heat-sealed cover in which the fixing of the said cover is facilitated by the structure of the container body. According to the invention, the container body (12) is defined by deep drawing a sheet metal blank, the bottom wall of this deep-drawn body is recessed in order to define a filling opening in it and a cover (16) is fixed to a flat rim (13) of the container body.

Description

I "Emballage métallique à opercule thermoscellé et procédé de fabricationI "Metal package with heat seal and process for manufacturing

d'un tel emballage" L'invention se rapporte à un nouveau type d'emballage à opercule thermoscellé dit "pelable", notamment destiné à la conserve apertisée, elle concerne également un procédé de  The invention relates to a new type of sealable seal packaging, especially for the apertised can, it also relates to a method of

fabrication d'un tel emballage.manufacture of such a package.

Dans le domaine des emballages métalliques, on distingue généralement les boîtes dites "trois pièces" et les boîtes dites "deux pièces" Une boîte "trois pièces" comporte un corps de boîte, par exemple cylindrique, un fond et un  In the field of metal packaging, there are generally three-piece boxes and two-box boxes. A three-piece box includes a box body, for example a cylindrical box, a bottom and a box.

couvercle rapportés aux deux extrémités dudit corps de boîte.  cover attached to both ends of said box body.

Dans ce type d'emballage, le fond est généralement fixé par sertissage tandis que le couvercle peut éventuellement comporter ou être constitué par un opercule thermoscellé sur un rebord dudit corps de boîte Ce dernier est défini par une plaque rectangulaire dont deux bords opposés sont rejoints et soudés Un tel corps de boîte comprend donc une soudure longitudinale et donc une surépaisseur plus ou moins prononcée, suivant la technique de soudure utilisée Dans le cas o l'emballage métallique comporte un opercule thermoscellé, cette surépaisseur pose un problème à la fois pour la formation du rebord de fixation de l'opercule et  In this type of packaging, the bottom is generally fixed by crimping while the lid may optionally comprise or be constituted by a heat seal on a rim of said box body The latter is defined by a rectangular plate whose two opposite edges are joined and Thus, such a box body comprises a longitudinal weld and therefore a greater or lesser thickness, depending on the welding technique used. In the case where the metal package comprises a heat seal, this extra thickness is a problem both for the formation the sealing flange of the lid and

pour la faisabilité et la fiabilité de son thermoscellage.  for the feasibility and reliability of its heat sealing.

Par ailleurs, une boîte dite "deux pièces" comporte un corps de boîte obtenu par emboutissage et un couvercle Ce  Furthermore, a so-called "two-piece" box comprises a box body obtained by stamping and a lid Ce

dernier peut aussi être un opercule thermoscellé.  last can also be a heat seal.

Il est à noter que l'industrie de la conserve alimentaire se répartit essentiellement en deux branches d'activité: le fabricant d'emballages métalliques et l'utilisateur de tels emballages, c'est-à-dire par exemple le conserveur qui traite les denrées alimentaires, remplit les boîtes et les ferme Une boîte "trois pièces" à opercule thermoscellé est appréciée du conserveur dans la mesure o le remplissage peut se faire par le fond, laissé ouvert, le sertissage de la paroi de fond étant une opération simple pouvant être réalisée facilement chez le conserveur En revanche, ce type de boîte est délicat à fabriquer et plus particulièrement, comme mentionné ci-dessus, le sous-ensemble constitué du corps de boîte et de l'opercule D'un autre côté, une boîte "deux pièces" à opercule thermoscellé doit être remplie par l'ouverture et l'opercule doit par conséquent être scellé chez le conserveur Il s'agit d'une opération délicate surtout lorsqu'elle est effectuée en  It should be noted that the food canning industry is essentially divided into two branches of activity: the manufacturer of metal packaging and the user of such packaging, that is to say, for example, the canner which processes the food, fills boxes and closes A box "three pieces" with heat seal is appreciated by the canister insofar as the filling can be done by the bottom, left open, crimping the bottom wall is a simple operation that can However, this type of box is difficult to manufacture and more particularly, as mentioned above, the subassembly consisting of the box body and the lid On the other hand, a box " two pieces "with heat-sealed lid must be filled by the opening and the seal must be sealed in the canner This is a delicate operation especially when it is performed e in

milieu "pollué"."polluted" environment.

L'invention propose un nouveau type de boîte réunissant tous les avantages des deux types de boîte connus, à la fois pour le fabricant d'emballage, s'agissant de la fixation de l'opercule et pour l'utilisateur ou conserveur, s'agissant du remplissage et des opérations finales de  The invention proposes a new type of box bringing together all the advantages of the two known types of box, both for the packaging manufacturer, with regard to the fixing of the lid and for the user or canner, acting on the filling and final operations of

fermeture de l'emballage.closing the package.

L'invention concerne donc un emballage métallique caractérisé en ce qu'il comporte en combinaison: un corps de boîte embouti; un opercule thermoscellé sur un rebord de l'ouverture dudit corps de boîte; et un fond rapporté et fixé à la place d'au moins une  The invention thus relates to a metal package characterized in that it comprises in combination: a stamped box body; a heat seal on a rim of the opening of said can body; and a bottom attached and fixed in place of at least one

partie de la paroi de fond dudit corps de boîte embouti.  part of the bottom wall of said pressed box body.

Ainsi, le corps de boîte ne comporte plus de soudure longitudinale puisqu'il est obtenu par emboutissage d'une t Ole et la formation du rebord de fixation de l'opercule de même que le thermoscellage peuvent s'effectuer dans de  Thus, the box body no longer comprises longitudinal welding since it is obtained by stamping a t Ole and the formation of the sealing flange of the seal as well as the heat sealing can be carried out in

meilleures conditions.best conditions.

Par ailleurs, l'utilisateur dispose d'une ouverture de remplissage ménagée dans le fond de l'emballage et la fermeture de ce dernier peut s'effectuer d'une façon  Furthermore, the user has a filling opening in the bottom of the package and closure of the latter can be done in a way

traditionnelle par le sertissage d'une paroi de fond.  traditional by crimping a bottom wall.

L'invention concerne également un procédé de fabrication d'un emballage métallique caractérisé en ce qu'il comprend notamment les opérations consistant: à emboutir un flan de métal de façon à définir un corps de boîte; à défoncer la paroi de fond dudit corps de boîte pour définir une ouverture munie d'un rebord de sertissage, et a thermosceller un opercule sur l'ouverture dudit  The invention also relates to a method of manufacturing a metal package characterized in that it comprises in particular the operations of: stamping a metal blank so as to define a box body; knocking down the bottom wall of said box body to define an opening provided with a crimping rim, and heat-sealing a lid on the opening of said

corps de boîte.box body.

Les opérations indiquées ci-dessus aboutissent à l'élaboration d'un élément d'emballage métallique prêt à remplir et destiné à être fermé par un simple sertissage d'une paroi de fond; ces deux dernières opérations étant  The above operations result in the development of a metal packaging element ready to fill and intended to be closed by a simple crimping of a bottom wall; these last two operations being

effectuées chez l'utilisateur.carried out at the user's premises.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la  The invention will be better understood and other advantages thereof will appear more clearly in the light of the

et faite en référence aux dessins annexés dans lesquels: les figures la, lb, lc illustrent schématiquement les principales opérations d'élaboration de l'emballage métallique conforme à l'invention, effectuées chez un fabricant d'emballages; les figures 2 a, 2 b illustrent schématiquement les opérations supplémentaires mises en oeuvre chez l'utilisateur; la figure 3 est une vue en élévation d'un emballage métallique conforme à l'invention, en forme d'assiette; la figure 4 est une vue de dessus de la figure 3; et  and with reference to the accompanying drawings, in which: FIGS. 1a, 1b, 1c schematically illustrate the main operations of producing the metal packaging according to the invention, carried out at a packaging manufacturer; Figures 2a, 2b schematically illustrate the additional operations implemented at the user; Figure 3 is an elevational view of a metal package according to the invention, shaped plate; Figure 4 is a top view of Figure 3; and

la figure 5 est une vue de dessous de la figure 3.  Figure 5 is a bottom view of Figure 3.

Sur les figures 1 et 2 illustrant la fabrication de l'emballage et son remplissage, les outillages, classiques en eux-mêmes, n'ont pas été représentés La fabrication du corps de boîte commence par le découpage d'un flan de t 8 le 11 (figure la) de forme et dimensions adéquates Ce flan subit ensuite un emboutissage (généralement par passes successives) analogue à celui qui serait mis en oeuvre pour la fabrication d'un corps de boîte d'une botte dite "deux pièces" Au niveau ou au voisinage de l'ouverture du corps de boîte 12, on définit un rebord annulaire plat 13 pour la fixation d'un  In Figures 1 and 2 illustrating the manufacture of the packaging and its filling, the tools, conventional in themselves, have not been shown The manufacture of the can body begins with the cutting of a blank of t 8 the 11 (Figure la) of adequate shape and dimensions This blank is then stamped (generally in successive passes) similar to that which would be implemented for the manufacture of a box body of a boot called "two pieces" At the level or in the vicinity of the opening of the box body 12, a flat annular flange 13 is defined for fixing a

opercule thermoscellé (figure lb>.heat sealed lid (Figure lb).

Selon une caractéristique importante de l'invention, l'emboutissage s'achève par un défonçage qui aboutit à la formation d'une ouverture de remplissage 14 s'ouvrant ici sur la plus grande partie de la paroi de fond du corps de boîte 12 Ce défonçage est effectué en laissant subsister une longueur droite permettant de former le rebord nécessaire au sertissage 15 La partie de la paroi de fond ainsi ouverte est destinée à recevoir ultérieurement un fond rapporté par sertissage Après la formation d'un tel corps de boîte défoncé à sa partie inférieure, un opercule 16 "pelable" est thermoscellé sur le rebord 13 (figure la) A titre d'exemple cet opercule est découpé dans une feuille composite elle- même composée d'une couche d'aluminium et d'une couche de matière plastique collées l'une contre l'autre, ce qui n'exclut pas l'utilisation d'autres matériaux L'opération de thermoscellage est classique et s'effectue dans les meilleures conditions puisque le rebord plat 13 est dépourvu de toute surépaisseur De plus, cette opération est réalisée chez le fabricant d'emballages métalliques Le dispositif intermédiaire représenté sur la figure lc est livré à l'utilisateur (le conserveur> en même temps qu'un fond 18 de forme et dimensions adaptées à celles de l'ouverture de remplissage 14 Ledit dispositif intermédiaire est alors rempli par l'ouverture 14 <figure 2 _ 1 et l'emballage est achevé par le sertissage du fond 18 <figure 2 b) qui vient  According to an important feature of the invention, the stamping is completed by a ripping which results in the formation of a filling opening 14 opening here over most of the bottom wall of the box body 12 Ce The portion of the bottom wall thus opened is intended to receive subsequently a crimped back base After the formation of such a box body smashed at its end, it is made to leave a straight length forming the flange required for crimping. lower part, a seal 16 "peelable" is heat-sealed on the flange 13 (Figure la) For example this operculum is cut in a composite sheet itself composed of a layer of aluminum and a layer of material plastics glued against each other, which does not exclude the use of other materials The heat sealing operation is conventional and is performed in the best conditions since the flat edge 13 is devoid of any extra thickness In addition, this operation is performed at the manufacturer of metal packaging The intermediate device shown in Figure lc is delivered to the user (the canister> together with a bottom 18 of shape and dimensions adapted to those of the filling opening 14 Said intermediate device is then filled by the opening 14 <Figure 2 _ 1 and the package is completed by crimping the bottom 18 <Figure 2 b) which comes

fermer définitivement l'ouverture de remplissage 14.  permanently close the filling opening 14.

Les figures 3 à 5 montrent, à titre d'exemple, un autre mode de réalisation d'un emballage métallique obtenu par mise en oeuvre de l'invention Il s'agit d'un emballage plus particulièrement destiné à contenir des produits alimentaires cuisinés Il est conformé en une sorte d'assiette permettant la consommation directe dans l'emballage On reconnaît les éléments principaux décrits plus haut, à savoir un corps de boîte embouti 12 a en forme de couronne de métal, un large rebord 13 a défini à la partie supérieure du corps de botte et formant également ici le rebord de l'assiette, un fond rapporté 18 a serti à la place d'une partie de la paroi de fond du corps de boîte embouti et enfin un opercule 16 a, souple et "pelable" thermosoudé sur le rebord 13 a de façon à obturer l'ouverture de l'emballage formant assiette Il est à noter que, comme précédemment, le thermoscellage de l'opercule 16 a est facilité par l'absence de toute surépaisseur sur le rebord 13 a, puisque le corps de boîte n'a pas été matérialisé par soudure. Il va de soi que l'invention couvre aussi le dispositif intermédiaire vide, tel que schématisé à la figure lc, et ne comportant que le corps de boîte embouti à fond ouvert et l'opercule 16 thermoscellé à une extrémité dudit  FIGS. 3 to 5 show, by way of example, another embodiment of a metal package obtained by implementation of the invention. It is a packaging more particularly intended to contain cooked food products. is formed in a kind of plate allowing direct consumption in the packaging is recognized the main elements described above, namely a stamped box body 12a in the form of a metal crown, a wide rim 13 has defined the party top of the boot body and also forming here the edge of the plate, an attached bottom 18 has crimped in place of a portion of the bottom wall of the stamped box body and finally a cap 16a, flexible and "peelable "heat-sealed on the rim 13a so as to seal the opening of the packaging plate It should be noted that, as before, the heat-sealing of the lid 16 is facilitated by the absence of any extra thickness on the flange 13 could the box body was not materialized by welding. It goes without saying that the invention also covers the empty intermediate device, as shown diagrammatically in FIG. 1c, and comprising only the open-bottomed box body and the heat-sealed lid 16 at one end of said device.
