Abstract
Description
emballage métallique, notamment pour produit en poudre et
procédé de fabrication d'un tel emballage"
L'invention se rapporte à un emballage métallique, notamment pour produit en poudre et concerne plus particulièrement une nouvelle structure de son bord d'ouverture; l'invention concerne également un procédé de fabrication d'un tel emballage.metal packaging, especially for powdered product and
process for manufacturing such packaging "
The invention relates to a metallic packaging, in particular for powdered product and relates more particularly to a new structure of its opening edge; the invention also relates to a method of manufacturing such packaging.
On connaît un emballage métallique pour produit pulvérulent, tel que café moulu ou lait en poudre, qui se compose d'un corps de boite, généralement tubulaire cylindrique, dont l'une des extrémités est obturée par un fond serti. Une large ouverture circulaire, occupe presque toute l'autre extrémité de l'emballage; elle est délimitée par un rebord périphérique interne de forme assez complexe, adapté à la fois pour accueillir un couvercle, souvent métallique et pour la fixation, par sa face intérieure, d'un opercule étanche, pouvant se présenter sous forme de feuillard (papier, plastique, aluminium, revêtus ou non, etc...) destiné à être découpé lors de la première ouverture de la boite. La présence de ce rebord périphérique interne présente plusieurs inconvénients.Sa structure relativement complexe rend l'emballage métallique coûteux à fabriquer. I1 doit en effet comporter une gorge assurant une certaine élasticité radiale pour faciliter l'encastrement étanche du couvercle tout en définissant une zone d'appui permettant de l'enlever à l'aide d'un objet quelconque formant levier. Le montage de l'opercule contre la face interne de ce rebord complique également la fabrication et oblige notamment à rapporter ledit rebord, par sertissage. De plus, la présence de ce rebord rend la boîte difficile à vider complètement de sorte qu'une certaine partie du produit en poudre est perdue. Enfin, le reste de l'opercule découpé forme une couronne relativement tranchante à la périphérie de l'ouverture, susceptible de blesser les utilisateurs, notamment les enfants. There is known a metallic packaging for powdery product, such as ground coffee or powdered milk, which consists of a box body, generally tubular cylindrical, one end of which is closed by a crimped bottom. A large circular opening occupies almost the entire other end of the packaging; it is delimited by an internal peripheral rim of a rather complex shape, suitable both for accommodating a cover, often metallic and for fixing, by its internal face, a tight seal, which can be in the form of a strip (paper, plastic, aluminum, coated or not, etc.) intended to be cut when the box is opened for the first time. The presence of this internal peripheral rim has several drawbacks; its relatively complex structure makes metallic packaging expensive to manufacture. I1 must indeed include a groove ensuring a certain radial elasticity to facilitate the tight fitting of the cover while defining a support zone allowing it to be removed using any object forming a lever. The mounting of the cover against the internal face of this rim also complicates the manufacture and in particular obliges to bring back said rim, by crimping. In addition, the presence of this rim makes it difficult to empty the box completely so that a certain part of the powdered product is lost. Finally, the rest of the cut lid forms a relatively sharp crown at the periphery of the opening, liable to injure users, in particular children.
L'invention permet de résoudre tous ces inconvénients. The invention overcomes all of these drawbacks.
Dans cet esprit, l'invention concerne donc essentiellement un emballage métallique comportant une ouverture dégageant sensiblement la totalité de l'une de ses faces d'extrémité, caractérisé en ce que ladite ouverture est délimitée par un rebord annulaire rabattu vers l'extérieur, et présentant un rétreint périphérique inclinant vers l'intérieur la face interne dudit rebord annulaire qui s'étend dans le prolongement de la paroi interne dudit emballage. In this spirit, the invention therefore essentially relates to a metal package comprising an opening which substantially releases all of one of its end faces, characterized in that said opening is delimited by an annular rim folded outwards, and having a peripheral constriction inclining inward the internal face of said annular rim which extends in the extension of the internal wall of said packaging.
Ainsi, la face interne du rebord annulaire rétreint se raccorde sans solution de continuité à la surface interne du corps de boite, puisqu'il s'agit en fait de la même paroi présentant en section un profil courbe ou un coude très ouvert. De ce fait, la boîte peut être complètement vidée, le rétreint définissant en fait une sorte d'entonnoir. Thus, the internal face of the narrowed annular rim is connected without continuity to the internal surface of the box body, since it is in fact the same wall having in section a curved profile or a very open bend. As a result, the box can be completely emptied, the constriction actually defining a sort of funnel.
En outre, une telle boîte, ainsi qu'il apparaîtra plus loin, est très simplifiée. Enfin, le profil d'une section d'un tel rebord annulaire est de préférence tel qu'il définisse extérieurement, une collerette d'extrémité plane sur laquelle un opercule étanche, du genre indiqué ci-dessus, peut être facilement adhérisé ou autrement fixé, par exemple, par thermo-scellage. Dans cet esprit, le rebord annulaire aura de préférence une section approximativement triangulaire. Le fait que l'opercule soit dorénavant scellé à la surface externe du rebord permet, à l'ouverture, de l'éliminer complètement, par exemple en le décollant, ce qui n'était pas possible avec l'emballage antérieur décrit ci-dessus.Pour la période de consommation du produit contenu dans l'emballage, ce dernier est obturé par un couvercle, en métal ou en matière plastique souple, livré emboîté sur la face externe du rebord annulaire de l'emballage, au-dessus de l'opercule. Ce couvercle protège ainsi efficacement l'opercule pendant la période de stockage. Son extraction est facilitée par un jonc circulaire asymétrique permettant l'appui d'une queue de cuillère, un ustensile ménager ou autre. In addition, such a box, as will appear below, is very simplified. Finally, the profile of a section of such an annular rim is preferably such that it defines externally, a flat end flange on which a tight seal, of the kind indicated above, can be easily adhered or otherwise fixed. , for example, by heat sealing. In this spirit, the annular rim will preferably have an approximately triangular section. The fact that the cover is now sealed on the outer surface of the rim allows, when opened, to eliminate it completely, for example by peeling it off, which was not possible with the prior packaging described above. .For the period of consumption of the product contained in the packaging, the latter is closed by a cover, of metal or flexible plastic material, delivered fitted on the external face of the annular rim of the packaging, above the operculum. This cover thus effectively protects the cover during the storage period. Its extraction is facilitated by an asymmetrical circular rod allowing the support of a spoon tail, a household utensil or other.
Enfin, il est à noter que le rebord rétreint à section triangulaire, tel que défini ci-dessus, présente un diamètre extérieur inférieur ou égal au diamètre extérieur du bourrelet de sertissage du fond, ce qui est avantageux pour le stockage et le transport de tels emballages. Finally, it should be noted that the narrowed rim of triangular section, as defined above, has an outside diameter less than or equal to the outside diameter of the bottom crimping bead, which is advantageous for the storage and transport of such packaging.
L'invention concerne par ailleurs, un procédé de fabrication d'un emballage métallique caractérisé en ce qu'il consiste successivement: - à définir un rebord annulaire enroulé vers l'extérieur le long du périmètre d'une ouverture d'un corps de boîte, et - à déformer ledit rebord annulaire roulé pour qu'il présente un rétreint périphérique. The invention also relates to a method of manufacturing a metallic package characterized in that it consists successively: - of defining an annular rim wound outwards along the perimeter of an opening of a box body , and - to deform said rolled annular rim so that it has a peripheral constriction.
L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre d'un emballage conforme à son principe et d'un procédé de fabrication d'un tel emballage, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels:
- la figure 1 est une vue partielle en coupe, selon un plan diamétral, de la partie supérieure d'un emballage métallique cylindrique en question; et
- les figures 2 à 5 illustrent schématiquement différentes étapes d'un procédé de fabrication possible de l'emballage de la figure 1.The invention will be better understood and other advantages thereof will appear more clearly in the light of the description which follows of a package conforming to its principle and of a method of manufacturing such a package, given only by way of example and with reference to the appended drawings in which:
- Figure 1 is a partial sectional view, along a diametral plane, of the upper part of a cylindrical metal package in question; and
FIGS. 2 to 5 schematically illustrate different stages of a possible manufacturing process for the packaging of FIG. 1.
L'emballage métallique tel que représenté à la figure 1 se compose d'un corps de boîte 12, cylindrique, dont une ouverture circulaire 13 occupe la presque totalité de l'une de ses faces d'extrémité. L'autre face d'extrémité du corps de boite est obturé par un fond, serti de façon classique. The metal packaging as shown in Figure 1 consists of a box body 12, cylindrical, of which a circular opening 13 occupies almost all of one of its end faces. The other end face of the box body is closed by a bottom, crimped in a conventional manner.
Sur le dessin, on distingue le fond 14 d'un autre emballage identique, empilé sur le premier, le sertissage définissant un bourrelet externe 15. L'ouverture 13 est obturée par un opercule 18 en aluminium lui-même protégé par un couvercle 19 en métal ou en matière plastique, susceptible de constituer un moyen de fermeture relativement hermétique, pendant la période d'utilisation de la boite par le consommateur. In the drawing, a distinction is made between the bottom 14 and another identical package, stacked on the first, the crimping defining an external bead 15. The opening 13 is closed by an aluminum cover 18 itself protected by a cover 19 in metal or plastic, capable of constituting a relatively hermetic closure means, during the period of use of the box by the consumer.
Selon l'invention, l'ouverture 13 est délimitée par un rebord annulaire 20 lui-même constitué par une portion de la paroi cylindrique du corps de boite 12, rabattue vers l'extérieur tout en présentant un rétreint périphérique R tel que la face interne 20a dudit rebord annulaire soit inclinée vers l'intérieur de l'emballage métallique tout en s'étendant dans le prolongement de la paroi interne 12a du corps de boite. Plus précisément, ladite face interne 20a du rebord annulaire est sensiblement tronconique et s'étend vers l'intérieur dans le prolongement de la paroi cylindrique 12a, sans solution de continuité avec celle-ci. According to the invention, the opening 13 is delimited by an annular rim 20 itself constituted by a portion of the cylindrical wall of the box body 12, folded outwards while presenting a peripheral constriction R such as the internal face 20a of said annular rim is inclined towards the inside of the metal packaging while extending in the extension of the internal wall 12a of the box body. More specifically, said internal face 20a of the annular rim is substantially frustoconical and extends inward in the extension of the cylindrical wall 12a, without a solution of continuity therewith.
Comme cela apparaît sur le dessin, le rebord annulaire peut se définir comme étant un roulé externe à section sensiblement triangulaire, en ce sens que le métal du corps de boite est roulé sur lui-même vers l'extérieur de façon à emprisonner son propre bord libre 22 tout en ayant une section radiale sensiblement triangulaire et définissant en particulier une collerette d'extrémité 24 plane. L'opercule 18 est simplement adhérisé par thermo-scellage sur cette collerette plane 24. il peut donc être le cas échéant, entièrement décollé, et non plus découpé, lors de la première ouverture de l'emballage. D'autre part, le roulé à section sensiblement triangulaire avec rétreint apparaît comme étant extrêmement peu encombrant radialement vers l'extérieur. Comme cela est visible sur la figure 1, la partie extérieure du rebord annulaire peut donc avoir un diamètre inférieur ou égal à celui du bourrelet extérieur 15 créé par le sertissage du fond.As can be seen in the drawing, the annular rim can be defined as being an external roll with a substantially triangular section, in the sense that the metal of the box body is rolled on itself towards the outside so as to trap its own edge free 22 while having a substantially triangular radial section and defining in particular a flat end flange 24. The cover 18 is simply adhered by heat-sealing on this flat flange 24. it can therefore be, if necessary, entirely detached, and no longer cut, when the packaging is opened for the first time. On the other hand, the roll with a substantially triangular cross-section with constriction appears to be extremely space-saving radially outwards. As can be seen in Figure 1, the outer part of the annular rim can therefore have a diameter less than or equal to that of the outer bead 15 created by crimping the bottom.
Les figures 2 à 5 illustrent les principales étapes de l'élaboration du roulé à section triangulaire 20. Pour ce faire, le corps de boîte 12 subit d'abord deux étapes de roulé externe (figures 2 et 3). Ceci peut se faire par enfoncement axial de deux outils 30, 31, successivement, présentant, chacun, une gorge de roulage; la gorge de l'outil 31 étant plus large que la gorge de l'outil 30. Le roulé à section approximativement circulaire ainsi obtenu est déformé entre deux outils 32, 33 pour lui donner une section approximativement rectangulaire. Cette opération est illustrée à la figure 4. L'outil 32, interne, présente une surface latérale approximativement cylindrique. L'outil 33 peut être constitué par une molette effectuant une rotation autour de l'outil 32 et comportant une gorge à section en C ou bien par un certain nombre de tronçons mobiles radialement et susceptibles d'être serrés simultanément en direction de la surface latérale de l'outil 32. Figures 2 to 5 illustrate the main steps in the development of triangular section rolled 20. To do this, the box body 12 first undergoes two external rolled steps (Figures 2 and 3). This can be done by axial insertion of two tools 30, 31, successively, each having a rolling groove; the groove of the tool 31 being wider than the groove of the tool 30. The roll of approximately circular section thus obtained is deformed between two tools 32, 33 to give it an approximately rectangular section. This operation is illustrated in FIG. 4. The internal tool 32 has an approximately cylindrical lateral surface. The tool 33 can be constituted by a knurling wheel rotating around the tool 32 and comprising a C-section groove or else by a certain number of sections movable radially and capable of being clamped simultaneously in the direction of the lateral surface. of tool 32.
Le roulé externe à section rectangulaire est ensuite à nouveau déformé entre deux outils 34 et 35 de façon à définir à la fois le rétreint périphérique et la section approximativement triangulaire. Pour cela, l'outil 34, interne, présente une gorge en V dont l'une des faces est perpendiculaire au corps de boite 12 pour définir le rebord annulaire 24. L'outil 35 a une structure équivalente à celle de l'outil 33 mais la ou les surfaces qui coopèrent avec l'outil 34 ne comportent aucune gorge. The external roll with rectangular section is then deformed again between two tools 34 and 35 so as to define both the peripheral constriction and the approximately triangular section. For this, the internal tool 34 has a V-shaped groove, one of the faces of which is perpendicular to the box body 12 to define the annular rim 24. The tool 35 has a structure equivalent to that of the tool 33 but the surface or surfaces which cooperate with the tool 34 have no groove.
