Definitions
- the invention relates to a method for opening the frangible shutter of a container type drink according to the preamble of the first claim, using a manipulator or manipulator reported reusable then for closing said drink box.
- the process is particularly interesting in that it brings many advantages in the manufacture and filling of beverage cans, as well as in their handling, storage and diffusion.
- a method of opening and filling a container of the formed beverage can type a normally metallic cylindrical body on which is crimped by a peripheral crimp hem a cover without grip and pull tab but provided with a frangible shutter which can be torn along a line of least resistance executed for this purpose to provide a partial opening by means of a manipulation, also called a case, which is just built in removably thanks to a capture well coming collaborate with a connecting member fixed by a rivet to the center of said cover to allow the case not only to pivot in the vertical plane by lifting its end close to the peripheral crimp hem around said organ, to leverage and push in the frangible shutter, by the other end provided with this effect of a reinforced leading edge, but still move in the horizontal plane around the same organ to close the opening by being clipped on the hem crimping device.
- the case that is used for opening and filling of the beverage cans is arranged on the cover in a very simple way; the case is indeed recessed on the connecting member by a simple pressure vertical, said member itself being shaped to lodge in a capture well located in the mass of the case in such a way that the leading edge at the front of said case comes to the frangible shutter right and that the back of the same case either to the right of the hem crimping, to initially constitute the element to break the frangible shutter, and the if necessary, in a second step, the element of filling by horizontal pivoting of the case around the rivet on a 180 ° angle sector.
- Such containers generally have a body cylindrical usually obtained by stamping a flat blank in mild steel or aluminum, one shrunk 3 being posteriorly made near the upper edge of said body on which a cover 4 is fixed also metallic by perimeter crimping forming a peripheral hem 5 particularly advantageous as it will be said later; the cover 4 is in known manner provided with a frangible shutter 6, which once torn following a line of least resistance executed at this effect, provides an opening 7 of overall shape sectoral, allowing consumption of the beverage contained in the box 2.
- the cutting of the shutter 6 is generally operated in the prior art by means of a pull tab usually including a grommet gripping, made from a thin sheet by bending adequate.
- This pull tab is secured to the box 2 by means of a rivet 8 in the center and above the cover 4 in such a way that by lifting said tab, it drives shutter 6 towards the inside of the levered container on rivet 8, before return naturally to a slightly tilted position from its original position.
- This connecting member 9 comprises essentially a horizontal axis 90 held in position horizontal a little above the upper face of the cover 4 by a deformable connecting piece joining the axis 90 to the cover 4.
- Axis 90 is such that it is able to collaborate with the case 1 provided for this purpose with a capture well in which is clipped or embedded axis 90 to secure the case 1 to the cover 4, as will be described later.
- the axis 90 can be mounted on a deformable connecting piece 91, for example a metal identical to that of the cover, as shown in Figure 3 a -left, c ' that is to say on the opposite side of the frangible obturator 6 with respect to the rivet 8, conversely on the same side as shown in FIG.
- the connecting member 9 consists of a deformable element advantageously made of metal similar to that of the cover 4, having the general shape of an L whose vertical wing 91 of rectangular shape horizontally supports the axis 90 by its longitudinal edge whose length is shorter than that of the axis 90 to create on either side of the wing 91 parts of overhanging axes 93 and 94; the horizontal wing of the element is intended to secure the connecting member 9 to the cover 4 by means of a rivet 8 from which it is derived (FIG. 3 c ) or which passes through it (FIG. 3 a and b ) allowing a rotation of the member centered on the rivet 8.
- the case 1 in general form of angular sector (without this form is not otherwise mandatory) is preferably obtained by injection of a material plastic inside a mold intended to produce great pace.
- Each case 1 has one side upper 11 and a lower face 12 intended to come in pressing on the cover 4, the two faces being joined by substantially vertical side walls 13 and 14 capable to form between them a volume to receive organs complementary likely to cooperate closely with the axis 90 and its connection to the cover 4, to form a device for opening and filling frangible shutter 6.
- a well is provided capture 10 from the underside 12 of the case 1, for extend vertically in the mass of the case symmetrically on either side of its plane of symmetry longitudinal, to form a longitudinal axis receptacle perpendicular to the longitudinal axis of symmetry of the case 1 coinciding substantially with a radius of the cover 4; such a well 10 is capable of accommodating freely but with a minimum clearance, the axis 90 which can thus gradually embed in it as you approach the case 1 of the surface of the cover 4 by a vertical translational movement as represented by the arrow A in figure 4.
- the capture well 10 presents according to a first execution of an entry area 101 whose vertical section in the longitudinal plane of symmetry is advantageously triangular flared down and narrowing vertically to a constriction 15 surmounted by a cavity 102 of circular section capable of receiving the axis 90 of the connecting member 9 when the case is in contact with the cover; it goes without saying that the passage section of the throttle 15 is smaller than the diameter of the axis 90 so as to retain it in the cavity 102, after a forceful passage through the constriction at the time of clipping.
- the well 10 has an area inlet 101 with parallel vertical walls or advantageously inclined from bottom to top; each wall is provided at the axis 90 attachment line on its connecting piece 91.92 of at least one flexible tab 103.104 extending substantially horizontally towards the other wall where it can, if necessary, lean vertically after being requested from bottom to top by the axis 90 at the time of its penetration into the cavity 102, during assembly; the tongues 103 and 104 are sized to come against the fixing line of axis 90 on its support, and / or under the parts protruding 93.94 from the axis 90 and resting on the wall in look, to constitute as many elements of restraint vertical of the axis 90 in the mass of the case 1.
- Case 1 further includes at one of its ends, a appendix 16 constituting a reinforced leading edge for act, as will be developed later, on the shutter frangible 6 which tears along a line of lesser resistance to form a definitive opening 7.
- a the other end of the case 1 means are provided for connection of the case to the crimping hem 5; such means are for example described in the European patent EP-0.558.422 already cited.
- these means 17 allow in particular to use the hem of crimping 5 of the cover 4 on the box 2 as a rail for circularly guide the case 1 when it is used for filling the opening 7 obtained by rotation said case 1 around the rivet 8 bringing its face lower 12 to the right of the opening 7 to close it; advantageously, the lower face 12 of the case 1 is provided with a bulge 18 whose shape is substantially identical to the general shape of the opening 7 and sufficient thickness to come fit just there and improve filling; of course and as outlined in the European patent, the connecting means 17 cooperating with the crimp hem 5 completes the compression of the bulge zone 18 inside the opening 7.
- the entrance to capture well 10 is arranged on the underside 12 of the case at one distance from the end comprising the connecting means 17 such as when they are on hem 5, member 9 fits exactly in well 10.
- this first alternative embodiment of the case 1 firstly provides the function of opening the beverage can, for example delivered with its case 1 factory fitted after filling and crimping the cover 4 on the case 2; the user must then release the connecting means 17 from the hem 5 in order to cause the case 1 in a vertical rotation around the connecting member 9 secured to the center of the cover 4 thanks to the rivet 8.
- the reinforced edge 16 comes to bear on the frangible shutter 6 which it smashes by leverage on the member 9.
- case 1 conforms to this second variant is broadly identical to case 1 of the previous variant, except for the connecting part coming to cooperate with the connection 9 and more particularly with the axis 90 integral with the cover 4 by means of a central rivet 8.
- the case 1 is provided with a capture well 20 arranged perpendicular to its longitudinal axis, but placed substantially in the center of the case 1 between its two ends 16 and 17 serving leading edge 16 respectively to detach the frangible cover 6 and clipping means 17 on the crimp hem 5 as mentioned in the previous variant.
- the well 20, allowing the vertical embedding of the axis 90 during the approximation from the case 1 to the cover 4, is associated with a channel translation 21 leading to well 20 and extending in a horizontal or inclined plane towards the edge reinforced 16 over a distance such as the axis 90, penetrating in the well 20 and passing through the translation channel 21 by retracting the case towards the hem of crimping in a plane substantially parallel to the plane of the cover and along a radial of it, either in abutment front of the translation channel, when the means of rear link 17 are in position to clip on the crimping hem 5.
- the front end of the translation channel 21 in this variant exactly coincides with the position of the well capture 10 in the first variant, which clearly shows the two half-views of Figure 1.
- the translation channel 21 ensuring the radial movement of case 1 after mounting on the member 9 must be such that once engaged, the axis 90 does not can no longer escape from said channel and join vertically the case 1 with the cover 4.
- the depth of the grooves 22 is chosen for just embed the overhanging parts 93 and 94 ( Figures 3) of the axis 90 relative to the part of link 91 of axis 90.
- the distance separating the two vertical blanks 24 of the channel translation 21 corresponds to the width of said piece of link 91.
- the capture well 20 can be improved by example by giving it a flared entry going in tapering to a similar longitudinal throttle at the throttle 15 of the well 10, above which opens into the translation channel 21 as described before.
- the advantage of this execution is to be able to clip the case 1 in the center of the cover 4 before filling and crimping on the box 2, in a single installation operation vertical.
- the box 2 as shown partially and schematically in Figure 5 is prepared with a cover 4 provided with a frangible shutter 6 (shown in solid lines in all the figures), crimped on the box 2 after filling, which provides a hem peripheral 5 in elevation relative to the face of the cover 4.
- the case 1 shaped according to the second variant is presented vertically along arrow C on the cover 4 so that the capture well 20 comes in line with the axis 90 horizontally disposed near the center of the cover 4 according to any of the variants detailed in FIGS. 3.
- the face lower 12 and more specifically the bulge 18 of the case 1 is found resting on the cover 4 of such so that it is fully included in the demarcated area by the peripheral hem 5 in accordance with FIG. 6; at at this instant, the connecting member 9 is fully implanted in the capture well 20 ensuring the maintenance, necessary case on the drink box 2 which can thus be stacked, stored and shipped anyway already known.
- the case 1 can be mounted on the connecting member 9 before the crimping of the cover 4, that is to say before filling, without interfering however, the subsequent crimping operation.
- This translation D will have the effect of displacing the axis 90 radially along the translation channel 21, the connecting element 91, 92 of the axis 90 sliding between the two lateral blanks 24 of said translation channel, and the protruding parts 93, 94 of the axis 90 passing through the two lateral grooves 22 emerging, as we have seen at the bottom of the capture well 20 and extending up to l 'before the translation channel 21 which abuts the axis 90 and thus secures the case 1 to the cover 4; the only possible movement is then a rotational movement in the direction of arrow E in FIG.
- the bottom 23 of the translation channel 21 may have an inclination relative to the flat bottom of the bulge 18.
- the inclination of the translation channel results from a slope given to the bottom 23 from the capture well 20 towards the center of the cover, that is to say towards the axis 90.
- the case 1 is translated towards the peripheral hem 5 as indicated by the arrow D in FIG. 7, it gradually undergoes a tightening between its bearing face and the upper face of the cover 4 so that at the time of the filling (FIG. 10) the pressure of the case 1 on the opening 7 is substantially increased, at least when that - it is clipped on hem 5.

Abstract
Description
L'invention concerne un procédé pour l'ouverture de l'obturateur frangible d'un récipient du type boíte à boisson conforme au préambule de la première revendication, utilisant un organe de manipulation ou un manipulateur rapporté réutilisable ensuite pour la fermeture de ladite boíte à boisson. Le procédé est particulièrement intéressant en ce qu'il apporte de nombreux avantages dans la fabrication et le remplissage des boítes à boisson, ainsi que dans leur manipulation, leur stockage et leur diffusion.The invention relates to a method for opening the frangible shutter of a container type drink according to the preamble of the first claim, using a manipulator or manipulator reported reusable then for closing said drink box. The process is particularly interesting in that it brings many advantages in the manufacture and filling of beverage cans, as well as in their handling, storage and diffusion.
On connaít déjà dans l'art antérieur quelques dispositifs de rebouchage de récipients de ce type comprenant un corps cylindrique, un fond et un couvercle sur lequel peut être pratiquée une ouverture de dimension globalement sectorielle inférieure à la dimension du couvercle, au moyen d'un obturateur frangible que l'on vient repousser à l'intérieur du récipient par l'effet de levier procuré par une languette de tirage maintenue au centre et au dessus dudit couvercle par un rivet.We already know in the prior art some closers for containers of this type comprising a cylindrical body, a bottom and a cover on which a dimension opening can be made overall sectoral less than the dimension of cover, by means of a frangible shutter which pushes back inside the container by the effect of lever provided by a pull tab held at the center and above said cover by a rivet.
Parmi les dispositifs de l'art antérieur, celui qui est décrit dans le brevet européen EP-0.558.422 est sans aucun doute le plus remarquable en ce qu'il est constitué d'un étui monté de manière amovible sur ou autour de la languette de tirage, avant ou après l'ouverture d'une boíte cylindrique métallique comportant un couvercle muni d'un obturateur frangible, pour constituer une patte mobile pivotante autour du rivet permettant de manipuler la languette de tirage sur la partie supérieure du couvercle, cet étui venant d'une part s'encastrer sur ladite languette de tirage, et d'autre part grâce à des bords périphériques extérieurs convenablement conformés, se clipper autour de l'ourlet périphérique de sertissage du couvercle sur le corps cylindrique de la boíte, cet ourlet servant alors de rail extérieur pour faciliter les déplacements circulaires de l'étui au dessus du couvercle.Among the devices of the prior art, that which is described in European patent EP-0.558.422 is without no doubt the most remarkable in that it is made up a case removably mounted on or around the pull tab, before or after opening a box cylindrical metal with a cover provided with a frangible shutter, to form a movable leg swivel around the rivet to manipulate the pull tab on the upper part of the cover, this case coming on the one hand to be embedded on said tongue on the other hand thanks to peripheral edges suitably shaped exteriors, clip around the peripheral crimping hem of the cover on the cylindrical body of the box, this hem then serving as outer rail to facilitate circular movements from the case above the lid.
Un avantage important de ce dispositif est que l'étui amovible peut être disposé sur la boíte après le remplissage et le sertissage du couvercle, ce qui constituait un progrès important par rapport aux solutions antérieures comme illustrées par exemple, dans le brevet US 4 463 866 qui prévoyait déjà une languette de tirage fixée par un rivet central au couvercle d'un récipient pour l'ouvrir par l'une de ses extrémités en enfonçant une partie frangible prévue sur le couvercle et refermer ensuite l'ouverture ainsi obtenue par rotation de 180° autour du rivet central de cette languette dont l'autre extrémité est conformée pour s'encastrer juste dans ladite ouverture.An important advantage of this device is that the case removable can be placed on the box after filling and crimping the lid, which was significant progress over solutions as illustrated for example in the US patent 4,463,866 which already provided for a fixed pull tab by a central rivet to the lid of a container for open it by one of its ends by pushing in a frangible part provided on the cover and close then the opening thus obtained by rotation of 180 ° around the central rivet of this tab, the other of which end is shaped to fit just in said opening.
De manière à proposer au consommateur une boíte à boisson équipée d'emblée de son étui de rebouchage, une opération de pose était donc nécessaire avant la diffusion commerciale du produit ; cette opération de pose se décomposait en trois phases essentielles
- levage de la languette de préhension saris déchirer l'obturateur frangible,
- propulsion de l'étui amovible pour l'encastrer sur ou autour de ladite languette,
- clippage par pression verticale de l'étui sur l'ourlet de sertissage.
- lifting the grip tab without tearing the frangible shutter,
- propulsion of the removable case for embedding it on or around said tongue,
- clipping by vertical pressure of the case on the crimp hem.
Cette opération de pose, technologiquement possible et économiquement abordable, se heurte néanmoins à une première série d'inconvénients : elle nécessite des automates de pose, du type carroussel ou peigne qui doivent travailler à très haute cadence avec beaucoup de précision pour soulever la languette métallique dans une première phase, sans pour autant perforer l'obturateur frangible ; d'un autre côté, il est nécessaire que les automates de pose soient implantés dans les locaux de remplissage du fabricant de boisson, en outre, l'implantation de l'étui sur le couvercle de la boíte apporte une surépaisseur sur l'ourlet périphérique qui peut gêner le transport et le stockage de telles boítes traditionnellement empilées les unes sur les autres.This laying operation, technologically possible and economically affordable, nevertheless faces a first series of drawbacks: it requires dispensing machines, of the carousel or comb type which must work at very high speed with great precision to lift the metal tab in a first phase, without piercing the frangible shutter; on the other hand, it is necessary that the automata of are installed in the filling rooms of the beverage manufacturer, in addition, the implantation of the case on the cover of the box provides extra thickness on the peripheral hem which can hinder transport and storage of such boxes traditionally stacked on top of each other.
Pour pallier tous ces inconvénients, il est proposé conformément à l'invention, un procédé d'ouverture et de rebouchage d'un récipient du type boíte à boissons formée d'un corps cylindrique normalement métallique sur lequel est serti par un ourlet périphérique de sertissage un couvercle démuni de languette de préhension et de tirage mais pourvu d'un obturateur frangible qui peut être déchiré selon une ligne de moindre résistance exécutée à cet effet pour procurer une ouverture partielle grâce à un organe de manipulation, appelé aussi étui, que l'on vient encastrer de manière amovible grâce à un puits de capture venant collaborer avec un organe de liaison fixé par un rivet au centre dudit couvercle pour permettre à l'étui non seulement de pivoter dans le plan vertical en soulevant son extrémité proche de l'ourlet périphérique de sertissage autour dudit organe, pour faire levier et enfoncer l'obturateur frangible, par l'autre extrémité munie à cet effet d'un bord d'attaque renforcé, mais encore de se déplacer dans le plan horizontal autour du même organe pour venir reboucher l'ouverture en étant clippé sur l'ourlet périphérique de sertissage.To overcome all these drawbacks, it is proposed according to the invention, a method of opening and filling a container of the formed beverage can type a normally metallic cylindrical body on which is crimped by a peripheral crimp hem a cover without grip and pull tab but provided with a frangible shutter which can be torn along a line of least resistance executed for this purpose to provide a partial opening by means of a manipulation, also called a case, which is just built in removably thanks to a capture well coming collaborate with a connecting member fixed by a rivet to the center of said cover to allow the case not only to pivot in the vertical plane by lifting its end close to the peripheral crimp hem around said organ, to leverage and push in the frangible shutter, by the other end provided with this effect of a reinforced leading edge, but still move in the horizontal plane around the same organ to close the opening by being clipped on the hem crimping device.
Pour une meilleure comparaison avec les dispositifs de l'art antérieur le plus proche déjà cités, à savoir le brevet européen EP-0.558.422, on préférera pour nommer l'organe de manipulation ou le manipulateur conforme à l'invention, utiliser systématiquement le terme étui, et ce, dans toute la suite du texte.For a better comparison with the devices of the closest prior art already cited, namely the European patent EP-0.558.422, we prefer to name the handling member or the manipulator according to the invention, systematically use the term case, and this, throughout the rest of the text.
Selon une première variante du procédé que l'on vient de décrire, l'étui qui est utilisé pour l'ouverture et le rebouchage des boítes à boisson est disposé sur le couvercle d'une manière très simple ; l'étui est en effet encastré sur l'organe de liaison par une simple pression verticale, ledit organe étant lui-même conformé pour se loger dans un puits de capture situé dans la masse de l'étui de telle façon que le bord d'attaque à l'avant dudit étui vienne au droit de l'obturateur frangible et que la partie arrière du même étui soit au droit de l'ourlet de sertissage, pour constituer dans un premier temps l'élément de tirage destiné à défoncer l'obturateur frangible, et le cas échéant, dans un deuxième temps, l'élément de rebouchage par pivotement horizontal de l'étui autour du rivet sur un secteur d'angle de 180°.According to a first variant of the process that we have just to describe, the case that is used for opening and filling of the beverage cans is arranged on the cover in a very simple way; the case is indeed recessed on the connecting member by a simple pressure vertical, said member itself being shaped to lodge in a capture well located in the mass of the case in such a way that the leading edge at the front of said case comes to the frangible shutter right and that the back of the same case either to the right of the hem crimping, to initially constitute the element to break the frangible shutter, and the if necessary, in a second step, the element of filling by horizontal pivoting of the case around the rivet on a 180 ° angle sector.
On comprend bien qu'une telle variante apporte d'indéniables avantages sur l'art antérieur en ce que la pose de l'étui en automatique, s'en trouve considérablement facilitée puisqu'il n'est plus nécessaire de soulever la languette ; il suffit d'une simple pression verticale pour amener l'étui sur la boíte et le clipper simultanément sur l'organe de liaison et l'ourlet de sertissage.We understand that such a variant brings undeniable advantages over the prior art in that the fitting the case automatically, is considerably facilitated since it is no longer necessary to lift the tongue; a simple vertical pressure is enough to bring the case on the box and clip it simultaneously on the connecting member and the crimp hem.
Néanmoins, un tel procédé conduit à disposer un étui d'emblée sur l'ourlet de sertissage, il est proposé selon une autre variante particulièrement achevée de l'invention, de solidariser l'étui au couvercle en deux temps : d'abord, par une pression verticale de l'étui sur l'organe de liaison qui vient s'encastrer dans un puits de capture prévu dans la masse de l'étui, ensuite par une translation radiale dans un plan sensiblement horizontal parallèlement au couvercle amenant le bord d'attaque de l'étui au droit de l'obturateur frangible et la partie arrière de l'étui à proximité de l'ourlet périphérique afin, ici encore, de constituer dans un premier temps l'élément de tirage pour défoncer l'obturateur frangible, et le cas échéant, dans un deuxième temps, l'élément de rebouchage par un pivotement horizontal de 180° de l'étui autour du rivet.However, such a method results in having a case immediately on the crimp hem, it is offered according to another particularly completed variant of the invention, to secure the case to the cover in two time: first, by vertical pressure of the case on the connecting member which comes to be embedded in a well of capture provided in the mass of the case, then by a radial translation in a substantially horizontal plane parallel to the cover bringing the leading edge of the case to the right of the frangible shutter and the part back of case near peripheral hem so here again to constitute at first the pulling element for smashing the frangible shutter, and if necessary, in a second step, the element of recapping by a 180 ° horizontal pivoting of the case around the rivet.
Selon cette dernière variante, il ressort de nouveaux avantages qui sont cette fois liés au fait que l'étui qui peut être translaté radialement sur le couvercle peut entièrement stationner dans l'espace intérieur délimité par l'ourlet de sertissage et la face du couvercle.According to this last variant, new ones emerge advantages which this time are linked to the fact that the case which can be translated radially on the cover can fully park in the interior space delimited by the crimp hem and the face of the cover.
On comprend alors que l'étui ainsi disposé ne constitue plus une gêne pour l'outil de sertissage du couvercle, avec l'heureuse conséquence qu'il peut être monté sur le couvercle avant le sertissage.We then understand that the case thus arranged does not is more of a nuisance for the crimping tool of the cover, with the happy consequence that it can be mounted on the cover before crimping.
De plus, un tel procédé simplifie la pose de l'étui et supprime des automates de pose sur les chaínes de remplissage ce qui évite en outre d'en perturber le déroulement ; le procédé permet également de réaliser une économie substantielle de métal tenant à la suppression partielle des languettes de tirage de l'art antérieur et d'économiser une partie des opérations de pliage liées à cette même languette. Enfin, un tel procédé qui évite les surépaisseurs de plastique sur l'ourlet périphérique l'étui étant provisoirement maintenu au centre du couvercle, est particulièrement avantageux pour le transport et le stockage des boítes à boisson qui s'effectueront de manière habituelle.In addition, such a method simplifies the installation of the case. and removes automatic machines from laying on the chains of filling which also avoids disturbing the unfolding; the method also makes it possible to carry out a substantial metal savings due to removal partial of the pull tabs of the prior art and to save part of the folding operations related to that same tab. Finally, such a process which avoids plastic extra thickness on the peripheral hem the case being temporarily held in the center of the cover, is particularly advantageous for transport and storage of beverage cans that will be done in a way usual.

En référence aux figures, on décrira ci-après deux
variantes préférées d'un étui amovible 1 mettant en oeuvre
le procédé tel qu'exposé au dessus, pour l'ouverture et le
rebouchage ultérieur de récipients du type boíte à
boisson 2.With reference to the figures, two below will be described
preferred variants of a
De tels récipients comportent généralement un corps
cylindrique habituellement obtenu par emboutissage d'un
flan plat en acier doux ou en aluminium, un rétreint 3
étant postérieurement réalisé à proximité du bord supérieur
dudit corps sur lequel on vient fixer un couvercle 4
également métallique par sertissage périmétrique formant un
ourlet périphérique 5 particulièrement avantageux comme il
sera dit plus loin ; le couvercle 4 est de manière connue
pourvu d'un obturateur frangible 6, qui une fois déchiré
suivant une ligne d'une moindre résistance exécutée à cet
effet, procure une ouverture 7 de forme globalement
sectorielle, permettant de consommer la boisson contenue
dans la boíte 2. Le découpage de l'obturateur 6 est
généralement opéré dans l'art antérieur au moyen d'une
languette de tirage comprenant habituellement un oeillet de
préhension, fabriquée à partir d'une tôle fine par pliage
adéquat. Cette languette de tirage est solidarisée à la
boíte 2 au moyen d'un rivet 8 au centre et au dessus du
couvercle 4 de telle manière qu'en soulevant ladite
languette, elle chasse l'obturateur 6 vers l'intérieur du
récipient par effet de levier sur le rivet 8, avant de
revenir naturellement à une position légèrement inclinée
par rapport à sa position initiale.Such containers generally have a body
cylindrical usually obtained by stamping a
flat blank in mild steel or aluminum, one
En référence aux figures 3 des dessins, et conformément à l'une des caractéristiques essentielles de l'invention, la languette de tirage équipant les solutions antérieures est supprimée pour être remplacée par un étui amovible 1 tel que représenté sur les figures 1 et 2 selon deux demi-vues présentant chacune une variante d'exécution.With reference to Figures 3 of the drawings, and in accordance with one of the essential characteristics of the invention, the pull tab fitted to the solutions is deleted to be replaced by a case removable 1 as shown in Figures 1 and 2 according to two half-views each presenting an alternative embodiment.
A la place de la languette de tirage, il est prévu un
organe de liaison 9 maintenu au centre du couvercle 4 par
un rivet 8. Cet organe de liaison 9 comporte
essentiellement un axe horizontal 90 maintenu en position
horizontale un peu au dessus de la face supérieure du
couvercle 4 par une pièce de liaison déformable
solidarisant l'axe 90 au couvercle 4.Instead of the pull tab, there is a
connecting member 9 held in the center of the
L'axe 90 est tel qu'il est apte à collaborer avec
l'étui 1 muni à cet effet d'un puits de capture dans lequel
vient se clipper ou s'encastrer l'axe 90 pour solidariser
l'étui 1 au couvercle 4, comme il sera décrit plus loin.Axis 90 is such that it is able to collaborate with
the
Conformément à des exécutions particulières
représentées dans les figures 3, l'axe 90 peut être monté
sur une pièce de liaison 91 déformable, par exemple un
métal identique à, celui du couvercle, telle que
représentée sur la figure 3a-gauche, c'est-à-dire du côté
opposé de l'obturateur frangible 6 par rapport au rivet 8
au inversement du même côté telle que représentée en
figure 3b-gauche, ou encore être directement issue du
rivet 8 grâce à une excroissance verticale 92, figure 3c ;
l'organe de liaison 9 est constitué d'un élément déformable
avantageusement en métal analogue à celui du couvercle 4,
ayant la forme générale d'un L dont l'aile verticale 91 de
forme rectangulaire supporte horizontalement l'axe 90 par
son bord longitudinal dont la longueur est plus courte que
celle de l'axe 90 pour créer de part et d'autre de
l'aile 91 des parties d'axes débordantes 93 et 94 ; l'aile
horizontale de l'élément est destinée à solidariser
l'organe de liaison 9 au couvercle 4 par le moyen d'un
rivet 8 dont il est issu (figure 3c) ou qui le traverse
(figure 3a et b) permettant une rotation de l'organe
centrée sur le rivet 8.In accordance with particular embodiments shown in Figures 3, the
Naturellement, on préférera l'une ou l'autre de ces exécutions ou leurs équivalents en fonction de critères de fabrication dans l'économie générale du dispositif de l'invention.Naturally, we will prefer one or the other of these executions or their equivalents based on manufacturing in the general economy of the device the invention.
Selon, une première variante mettant en oeuvre le
procédé conforme à l'invention, et en référence aux demi-vues
de droite des figures 1 et 2, et à la figure 4,
l'étui 1 en forme générale de secteur angulaire (sans que
cette forme ne soit d'ailleurs obligatoire) est
préférentiellement obtenu par injection d'une matière
plastique à l'intérieur d'un moule prévu pour produire à
grande cadence. Chaque étui 1 comporte une face
supérieure 11 et une face inférieure 12 destinée à venir en
appui sur le couvercle 4, les deux faces étant réunies par
des parois latérales 13 et 14 sensiblement verticales aptes
à former entre-elles un volume pour recevoir des organes
complémentaires susceptibles de coopérer étroitement avec
l'axe 90 et sa liaison au couvercle 4, pour former un
dispositif permettant l'ouverture et le rebouchage
ultérieur de l'obturateur frangible 6.According to a first variant implementing the
process according to the invention, and with reference to the half-views
on the right of Figures 1 and 2, and in Figure 4,
the
A cet effet, et conformément à cette première
variante économique de l'étui 1, il est prévu un puits de
capture 10 issu de la face inférieure 12 de l'étui 1, pour
se prolonger verticalement dans la masse de l'étui
symétriquement de part et d'autre de son plan de symétrie
longitudinal, pour former un réceptacle longitudinal d'axe
perpendiculaire à l'axe de symétrie longitudinal de
l'étui 1 coïncidant sensiblement avec un rayon du
couvercle 4 ; un tel puits 10 est susceptible d'accueillir
librement mais avec un jeu minimum, l'axe 90 qui peut ainsi
s'y encastrer progressivement au fur et à mesure que l'on
approche l'étui 1 de la surface du couvercle 4 par un
mouvement de translation vertical tel que représenté par la
flèche A de la figure 4.To this end, and in accordance with this first
economic variant of
Conformément eux dessins, notamment de la figure 4,
le puits de capture 10 présente selon une première
exécution une zone d'entrée 101 dont la section verticale
dans le plan de symétrie longitudinal est avantageusement
triangulaire évasée vers le bas et se rétrécissant
verticalement jusqu'à un étranglement 15 surmonté par une
cavité 102 de section circulaire apte à recevoir l'axe 90
de l'organe de liaison 9 lorsque l'étui est au contact du
couvercle ; il va de soi que la section de passage de
l'étranglement 15 est plus faible' que le diamètre de
l'axe 90 de manière à le retenir dans la cavité 102, après
un passage en force dans l'étranglement au moment du
clippage.According to their drawings, in particular of FIG. 4,
the capture well 10 presents according to a first
execution of an
Selon une autre exécution détaillée sur le deuxième
arraché de la figure 4, le puits 10 présente une zone
d'entrée 101 à parois verticales parallèles ou
avantageusement inclinées de bas en haut ; chaque paroi est
munie au niveau de la ligne de fixation de l'axe 90 sur sa
pièce de liaison 91,92 d'au moins une languette flexible
103,104 s'étendant sensiblement horizontalement vers
l'autre paroi où elle peut, le cas échéant, s'appuyer
verticalement après avoir été sollicitée de bas en haut par
l'axe 90 au moment de sa pénétration dans la cavité 102,
lors du montage ; les languettes 103 et 104 sont
dimensionnées pour venir contre la ligne de fixation de
l'axe 90 sur son support, et/ou sous les parties
débordantes 93,94 de l'axe 90 et en appui sur la paroi en
regard, pour constituer autant d'éléments de retenue
verticale de l'axe 90 dans la masse de l'étui 1.According to another detailed execution on the second
torn from Figure 4, the
L'étui 1 conformément à cette première variante
comporte en autre à l'une de ses extrémités, un
appendice 16 constituant un bord d'attaque renforcé pour
agir, comme il sera développé plus loin, sur l'obturateur
frangible 6 qui se déchire suivant une ligne de moindre
résistance pour former une ouverture définitive 7. A
l'autre extrémité de l'étui 1, on prévoit des moyens de
liaison de l'étui sur l'ourlet de sertissage 5 ; de tels
moyens sont par exemple décrits dans le brevet européen
EP-0.558.422 déjà cité. On notera d'ailleurs que ces moyens
de liaison 17 permettent notamment d'utiliser l'ourlet de
sertissage 5 du couvercle 4 sur la boíte 2 comme rail pour
guider circulairement l'étui 1 lorsque celui-ci est utilisé
pour le rebouchage de l'ouverture 7 obtenu par rotation
dudit étui 1 autour du rivet 8 amenant sa face
inférieure 12 au droit de l'ouverture 7 pour l'obturer ;
avantageusement, la face inférieure 12 de l'étui 1 est
munie d'un renflement 18 dont la forme est sensiblement
identique à la forme générale de l'ouverture 7 et
l'épaisseur suffisante pour venir s'y encastrer juste et
améliorer le rebouchage ; bien entendu et comme exposé dans
le brevet européen, les moyens de liaison 17 coopérant avec
l'ourlet de sertissage 5 viennent parfaire la compression
de la zone de renflement 18 à l'intérieur de l'ouverture 7.
Il est à noter que l'entrée du puits de capture 10
est disposée sur la face inférieure 12 de l'étui à une
distance de l'extrémité comportant les moyens de liaison 17
telle que lorsqu'ils sont sur l'ourlet 5, l'organe 9
s'encastre exactement dans le puits 10.Note that the entrance to capture well 10
is arranged on the underside 12 of the case at one
distance from the end comprising the connecting
Ainsi constituée, cette première variante d'exécution
de l'étui 1 procure d'abord la fonction d'ouverture de la
boíte à boisson par exemple livrée avec son étui 1 monté en
usine après remplissage et sertissage du couvercle 4 sur la
boíte 2 ; l'utilisateur doit alors dégager les moyens de
liaison 17 de l'ourlet 5 afin d'entraíner l'étui 1 dans une
rotation verticale autour de l'organe de liaison 9
solidaire du centre du couvercle 4 grâce au rivet 8. Dans
ce mouvement de rotation vertical, le bord renforcé 16
vient en appui sur l'obturateur frangible 6 qu'il défonce
par effet de levier sur l'organe 9. Une fois l'obturateur 6
enfoncé à l'intérieur de la boíte 2, il suffit de
rebasculer dans une rotation inverse l'étui 1 pour venir
suivant flèche B de la figure 4 clipper l'étui 1 sur
l'ourlet 5 au moyen de ses organes de liaison 17, l'étui 1
étant alors en position pour être utilisé en, rebouchage
après consommation du liquide contenu à l'intérieur de la
boíte 2 ; pour cela il suffira d'effectuer une rotation de
180° le long de l'ourlet 5 servant de guidage circulaire
pour amener la zone de renflement 18 au droit de
l'ouverture 7 et constituer un bouchage relativement
efficace comme il a été dit précédemment.Thus constituted, this first alternative embodiment of the
En référence aux demi-vues de gauche des figures 1 et 2 et aux figures 5 à 10, il sera maintenant décrit une variante particulièrement efficace et préférée d'un étui amovible 1 mettant en oeuvre le procédé général conforme à l'invention.With reference to the left half-views of Figures 1 and 2 and in FIGS. 5 to 10, there will now be described a particularly effective and preferred variant of a case removable 1 implementing the general method according to the invention.
Dans sa structure générale l'étui 1 conforme à cette
deuxième variante est globalement identique à l'étui 1 de
la variante précédente, sauf pour ce qui concerne la
partie de liaison venant coopérer avec l'organe de
liaison 9 et plus spécialement avec l'axe 90 solidaire du
couvercle 4 par le moyen d'un rivet central 8.In its general structure the
Conformément aux vues de gauche des figures 1 et 2
montrant la partie ventrale de l'étui 1 et sa section au
niveau du dispositif de liaison (figure 2), l'étui 1 est
muni d'un puits de capture 20 disposé perpendiculairement à
son axe longitudinal, mais placé sensiblement au centre de
l'étui 1 entre ses deux extrémités 16 et 17 servant
respectivement de bord d'attaque 16 pour détacher
l'opercule frangible 6 et de moyen de clippage 17 sur
l'ourlet de sertissages 5 comme il a été dit dans la
variante précédente.In accordance with the left views of Figures 1 and 2
showing the ventral part of
Selon une exécution préférée, le puits 20, permettant
l'encastrement vertical de l'axe 90 lors du rapprochement
de l'étui 1 vers le couvercle 4, est associé à un canal de
translation 21 débouchant sur le puits 20 et s'étendant
dans un plan horizontal ou incliné en direction du bord
renforcé 16 sur une distance telle que l'axe 90, pénétrant
dans le puits 20 et empruntant le canal de translation 21
par un recul de l'étui en direction de l'ourlet de
sertissage dans un plan sensiblement parallèle au plan du
couvercle et suivant une radiale de celui-ci, soit en butée
avant du canal de translation, lorsque les moyens de
liaison arrière 17 sont en position pour se clipper sur
l'ourlet de sertissage 5. On observera d'ailleurs que
l'extrémité avant du canal de translation 21 dans cette
variante, coïncide exactement avec la position du puits de
capture 10 dans la première variante, ce que montrent bien
les deux demi-vues de la figure 1.According to a preferred embodiment, the
Naturellement, le canal de translation 21 assurant le
mouvement radial de l'étui 1 après son montage sur
l'organe 9 doit être tel qu'une fois engagé, l'axe 90 ne
puisse plus s'échapper dudit canal et solidarise
verticalement l'étui 1 au couvercle 4. Pour cela il est
prévu sur chaque flan 24 délimitant verticalement le
canal 21, une rainure 22 élargissant latéralement le
fond 23 du canal 21 sur une hauteur équivalente ou
légèrement supérieure au diamètre de l'axe 90, donnant au
canal 21, une section verticale transverse en forme de T.Naturally, the
La profondeur des rainures 22 est choisie pour
encastrer juste les parties débordantes 93 et 94
(figures 3) de l'axe 90 par rapport à la pièce de
liaison 91 de l'axe 90. Avantageusement, la distance
séparant les deux flans verticaux 24 du canal de
translation 21 correspond à la largeur de ladite pièce de
liaison 91.The depth of the
Enfin il est clair que les rainures 22 débouchent en
fond du puits de capture 20, ce qui permet à l'axe 90 après
son déplacement vertical au moment de l'encastrement de
l'étui 1 sur le couvercle 4, d'entrer dans les rainures
latérales 22 pour permettre une translation radiale à
l'étui en direction de l'ourlet le sertissage 5 sur lequel
il sera ultérieurement clippé, comme il sera expliqué dans
les lignes qui suivent en référence aux figures 5 à 10.Finally, it is clear that the
Il va de soit que, à l'instar de la première
variante, le puits de capture 20 peut être perfectionné par
exemple en lui donnant une entrée évasée allant en
s'amenuisant jusqu'à un étranglement longitudinal, analogue
à l'étranglement 15 du puits 10, au dessus duquel on
débouche dans le canal de translation 21 tel que décrit
avant.It goes without saying that, like the first
alternatively, the capture well 20 can be improved by
example by giving it a flared entry going in
tapering to a similar longitudinal throttle
at the
L'avantage de cette exécution est de pouvoir clipper
l'étui 1 au centre du couvercle 4 avant remplissage et
sertissage sur la boíte 2, en une seule opération de pose
verticale.The advantage of this execution is to be able to clip
the
La boíte 2 telle que représentée partiellement et
schématiquement en figure 5 est préparée avec un
couvercle 4 muni d'un obturateur frangible 6 (figuré en
trait plein sur toutes les figures), serti sur la boíte 2
après son remplissage, ce qui procure un ourlet
périphérique 5 en surélévation par rapport à la face du
couvercle 4. L'étui 1 conformé selon la seconde variante
d'exécution, est présenté verticalement suivant flèche C
sur le couvercle 4 de telle manière que le puits de
capture 20 vienne au droit de l'axe 90 horizontalement
disposé à proximité du centre du couvercle 4 selon l'une
quelconque des variantes détaillées aux figures 3.The
Selon cette première approche verticale, la face
inférieure 12 et plus spécifiquement le renflement 18 de
l'étui 1 se retrouve en appui sur le couvercle 4 de telle
sorte qu'il soit entièrement compris dans l'aire délimitée
par l'ourlet périphérique 5 conformément à la figure 6 ; à
cet instant, l'organe de liaison 9 est entièrement implanté
dans le puits de capture 20 assurant le maintien,
nécessaire de l'étui sur la boíte à boisson 2 qui peut
ainsi être empilée, stockée et expédiée de toute manière
déjà connue. A noter d'ailleurs que l'étui 1 peut être
monté sur l'organe de liaison 9 avant le sertissage du
couvercle 4, c'est-à-dire avant remplissage, sans gêner
pour autant l'opération de sertissage ultérieur.According to this first vertical approach, the face
lower 12 and more specifically the
Conformément à la figure 7, lorsque l'on veut
consommer le liquide contenu dans la boíte 2 il convient
alors de détacher l'opercule 6 en utilisant bien entendu
l'étui 1 conformément au procédé de l'invention. Selon les
figures 7 et 8, pour l'ouverture de la boíte 2, l'opérateur
devra saisir l'extrémité de l'étui 1 la plus proche de
l'ourlet 5, la soulever légèrement pour échapper la
surélévation dudit ourlet 5 et imprimer une translation
dans le sens de la flèche D, figure 7. Cette translation D
aura pour effet de déplacer radialement l'axe 90 le long du
canal de translation 21, l'élément de liaison 91,92 de
l'axe 90 coulissant entre les deux flans latéraux 24 dudit
canal de translation, et les parties débordantes 93,94 de
l'axe 90 empruntant les deux rainures latérales 22
débouchant, comme on l'a vu au fond du puits de capture 20
et s'étendant jusqu'à l'avant du canal de translation 21 où
vient en buter l'axe 90 et vient ainsi solidariser l'étui 1
au couvercle 4 ; le seul mouvement possible est alors un
mouvement de rotation dans le sens de la flèche E de la
figure 8 ; lorsque cette rotation est prolongée
verticalement, le bord d'attaque renforcé 16 de l'étui 1
vient alors au contact de la zone frangible de
l'obturateur 6 et par effet de levier autour de l'organe
déformable 9 maintenu par le rivet 8, l'obturateur 6 est
repoussé à l'intérieur de la boíte conformément à la
flèche F de la figure 8. Bien entendu, l'obturateur 6 ainsi
repoussé reste en cette position et procure l'ouverture 7
pour la consommation du liquide. Pour mieux dégager
l'ouverture 7, l'étui 1, conformément à la figure 9, est
ensuite repoussé par une rotation inverse suivant la
flèche G de la figure 9 et clippé sur l'ourlet 5 au moyen
des organes de liaison 17 comme décrit plus haut. On
observera que ce clippage sur l'ourlet 5 s'impose puisqu'à
défaut l'étui 1 resterait en position inclinée tenant à la
déformation de la pièce de liaison 91,92 sollicitée dans le
mouvement de la figure 8 au moment de l'ouverture de
l'obturateur. Enfin et utilisant alors l'ourlet 5 comme
rail de guidage, l'utilisateur qui souhaite reboucher
momentanément la boíte 2 pour une consommation ultérieure,
pourra amener par une simple rotation horizontale autour du
rivet 8 selon la flèche R de la figure 10, l'étui 1 au
droit de l'ouverture 7 dans laquelle le renflement 18
viendra s'encastrer procurant un rebouchage pratiquement
étanche ne dépendant finalement que de la compression de
l'étui sur l'ouverture 7.According to Figure 7, when you want to consume the liquid in the
Selon une dernière caractéristique de l'invention, il
est possible d'augmenter la compression du rebouchage ; à
cet effet, le fond 23 du canal de translation 21 peut
présenter une inclinaison par rapport au fond plat du
renflement 18. L'inclinaison du canal de translation
résulte d'une pente donnée au fond 23 depuis le puits de
capture 20 vers le centre du couvercle, c'est-à-dire vers
l'axe 90. De cette façon, au fur et à mesure que l'étui 1
est translaté vers l'ourlet périphérique 5 tel qu'indiqué
par la flèche D en figure 7, il subit progressivement un
serrage entre sa face d'appui et la face supérieure du
couvercle 4 de sorte qu'au moment du rebouchage (figure 10)
on augmente sensiblement la pression de l'étui 1 sur
l'ouverture 7, du moins lorsque celui-ci est clippé sur
l'ourlet 5. According to a last characteristic of the invention, it is possible to increase the compression of the filling; for this purpose, the bottom 23 of the
Il est bien évident que toutes combinaisons
différentes des variantes d'exécution telles que décrites
ci-avant utilisant par exemple les diverses formes
d'organes de liaison liées au couvercle ou à l'étui, ou
d'autres solutions équivalentes non décrites, ne
sortiraient pas de l'invention pour autant que la nouvelle
variante mette en oeuvre le procédé conforme à
l'invention ; ce serait notamment le cas où l'on
remplacerait l'axe 90 par une sphère attachée au rivet 8
coopérant avec un puits de capture et, le cas échéant, un
canal de translation par exemple tubulaire.It is obvious that all combinations
different from the execution variants as described
above using for example the various forms
connecting members linked to the cover or to the case, or
other equivalent solutions not described, do not
not come out of the invention as far as the new
variant implements the process according to
the invention; this would be particularly the case where one
would replace the
