Description

DESCRIPTION DESCRIPTION
TITRE : Boîte de conserve avec ouverture de vidange de liquide TITLE: Tin can with liquid drain opening
[Domaine technique] [Technical area]
L'invention se rapporte à une boîte de conserve. The invention relates to a tin can.
Elle se rapporte plus particulièrement à une boîte de conserve comprenant un corps tubulaire présentant deux extrémités opposées fermées respectivement par un couvercle inférieur et un couvercle supérieur. It relates more particularly to a tin can comprising a tubular body having two opposite ends closed respectively by a lower lid and an upper lid.
[Etat de la technique] [State of the art]
De manière connue, dans une boîte de conserve, le couvercle supérieur présente une partie supérieure amovible délimitée par une ligne supérieure d'amorce de rupture et équipée d'un organe supérieur d'ouverture, formant ainsi un système d'ouverture dit facile ou « EOE » pour « Easy Open End ». In known manner, in a tin can, the upper lid has a removable upper part delimited by an upper line of incipient rupture and equipped with an upper opening member, thus forming a so-called easy opening system or " EOE” for “Easy Open End”.
Généralement, pour une boîte de conserve contenant un contenu solide (des denrées alimentaires) baignant dans un contenu liquide (un jus), la partie supérieure amovible présente une superficie au moins supérieure à 90% d'une superficie du couvercle supérieur pour pouvoir vider la boîte de conserve de l'intégralité de ses denrées alimentaires ; on parle classiquement d'une ouverture intégrale sur le couvercle supérieur. Generally, for a can containing a solid content (foodstuffs) immersed in a liquid content (a juice), the removable upper part has an area at least greater than 90% of an area of the upper cover to be able to empty the can of all of its foodstuffs; one speaks classically of an integral opening on the upper cover.
Cependant, pour séparer les denrées alimentaires du jus, il faut faire appel des solutions pas entièrement satisfaisantes, comme par exemple légèrement entrebâiller la partie supérieure amovible pour écouler le jus, ou employer une passoire dans laquelle on vide à la fois les denrées alimentaires et le jus. However, to separate the foodstuffs from the juice, it is necessary to resort to solutions that are not entirely satisfactory, such as for example opening the removable upper part slightly to drain the juice, or using a strainer into which both the foodstuffs and the juice are emptied. juice.
[Résumé de l'invention] [Summary of Invention]
L'invention propose une solution facile, rapide et économique pour séparer les denrées alimentaires du jus, autrement dit purger le contenu solide du contenu liquide, avec la boîte de conserve métallique, et sans faire appel à un appareil externe. The invention proposes an easy, fast and economical solution for separating the foodstuffs from the juice, in other words purging the solid content from the liquid content, with the metal can, and without using an external device.
Ainsi, l'invention propose une boîte de conserve comprenant un corps tubulaire présentant deux extrémités opposées fermées respectivement par un couvercle inférieur et un couvercle supérieur, dans laquelle le couvercle supérieur présente une partie supérieure amovible délimitée par une ligne supérieure d'amorce de rupture et équipée d'un organe supérieur d'ouverture, cette partie supérieure amovible présentant une superficie au moins supérieure à 90% d'une superficie du couvercle supérieur pour pouvoir vider la boîte de conserve de denrées alimentaires, ladite boite de conserve étant remarquable en ce que le couvercle inferieur présente une partie inférieure amovible délimitée par une ligne inférieure d'amorce de rupture et équipée d'un organe inférieur d'ouverture, une telle partie inférieure amovible présentant au moins une section principale longiligne présentant une largeur de valeur inférieure ou égale à 3 millimètres et une longueur de valeur supérieure ou égale à 10 millimètres, pour pouvoir vidanger la boîte de conserve d'un jus liquide en préalable de la vider des denrées alimentaires. Thus, the invention proposes a tin can comprising a tubular body having two opposite ends closed respectively by a lower lid and an upper lid, in which the upper lid has a removable upper part delimited by an upper line of incipient rupture and equipped with an upper opening member, this removable upper part having an area at least greater than 90% of an area of the upper cover in order to be able to empty the can of foodstuffs, said tin can being remarkable in that the lower lid has a removable lower part delimited by a lower line of incipient rupture and equipped with a lower opening member, such a removable lower part having at least one slender main section having a width of value less than or equal to 3 millimeters and a length of value greater than or equal to 10 millimeters, in order to be able to empty the can of a liquid juice before emptying it of foodstuffs.
L'invention propose donc de purger les denrées alimentaires du jus liquide au travers d'une ouverture inférieure définie par la partie inférieure amovible qui, une fois ouverte, présente au moins une telle section principale longiligne. Autrement dit, cette ouverture inférieure formera une ouverture inférieure de vidange servant à vider le jus liquide, sans laisser fuiter les denrées alimentaires, et ceci grâce à la forme mince et oblongue, plus longue que large, de la section principale longiligne. Sa finesse (largeur inférieure ou égale à 3 mm) assure que les denrées alimentaires ne viennent pas passer au travers de l'ouverture inférieure de vidange, et sa longueur (longueur supérieure ou égale à 10 millimètres) assure que les denrées alimentaires ne viennent pas boucher l'ouverture inférieure de vidange tout en offrant une superficie de vidange accrue pour pouvoir vidanger rapidement le jus liquide. The invention therefore proposes to purge the foodstuffs of the liquid juice through a lower opening defined by the removable lower part which, once opened, has at least such an elongated main section. In other words, this lower opening will form a lower drain opening serving to empty the liquid juice, without letting the foodstuffs leak out, and this thanks to the thin and oblong shape, longer than wide, of the slender main section. Its thinness (width less than or equal to 3 mm) ensures that foodstuffs do not come through the lower drain opening, and its length (length greater than or equal to 10 millimeters) ensures that foodstuffs do not come block the lower drain opening while providing an increased drain area to quickly drain the liquid juice.
Selon une possibilité, la section principale longiligne est rectiligne ou incurvée. According to one possibility, the slender main section is straight or curved.
Selon une autre possibilité, la longueur de la section principale longiligne présente une valeur comprise entre 10 et 50 millimètres. According to another possibility, the length of the elongated main section has a value of between 10 and 50 millimeters.
Selon une autre possibilité, la largeur de la section principale longiligne présente une valeur comprise entre 1 et 2 millimètres. According to another possibility, the width of the longilinear main section has a value of between 1 and 2 millimeters.
Dans une réalisation particulière, la partie inférieure amovible présente au moins une section secondaire longiligne, reliée à la section principale longiligne et s'étendant transversalement vis-à-vis de la section principale longiligne, où ladite section secondaire longiligne présente une largeur de valeur inférieure ou égale à 2 millimètres et une longueur de valeur supérieure ou égale à 5 millimètres. In a particular embodiment, the removable lower part has at least one elongated secondary section, connected to the elongated main section and extending transversely with respect to the elongated main section, where said elongated secondary section has a width of less or equal to 2 millimeters and a length of value greater than or equal to 5 millimeters.
Ainsi, l'ouverture inférieure de vidange présente deux ou plus sections longilignes et fines qui se croisent, augmentant ainsi la superficie de vidange, tout en évitant que ne s'échappent les denrées alimentaires car ces plus sections longilignes sont toutes fines (largeur inférieure ou égale à 3 mm). Thus, the lower drain opening has two or more elongated and thin sections which intersect, thus increasing the draining surface, while preventing foodstuffs from escaping because these longer slender sections are all thin (lower width or equal to 3 mm).
Selon une possibilité, la section secondaire longiligne est rectiligne ou incurvée. Dans un mode de realisation particulier, la section principale longiligne et la section secondaire longiligne définissent à elles deux une forme en « X », en « T », en « L », en « Y » ou en « V ». According to one possibility, the longilinear secondary section is rectilinear or curved. In a particular embodiment, the elongated main section and the elongated secondary section together define an "X", "T", "L", "Y" or "V" shape.
Ainsi, si une seule section secondaire longiligne est prévue, alors l'ouverture inférieure de vidange aura une forme en « X », en « T », en « L », en « Y » ou en « V ». Thus, if only one slender secondary section is provided, then the lower drain opening will have an "X", "T", "L", "Y" or "V" shape.
En variante, si deux ou plus sections secondaires longilignes sont prévues, alors l'ouverture inférieure de vidange peut avoir une forme plus complexe, par exemple en « E », en « H », en « W », en « F », en « Z », etc. Alternatively, if two or more slender secondary sections are provided, then the lower drain opening may have a more complex shape, for example "E", "H", "W", "F", “Z”, etc.
Selon une autre possibilité, la longueur de la section secondaire longiligne présente une valeur comprise entre 5 et 30 millimètres. According to another possibility, the length of the longilinear secondary section has a value of between 5 and 30 millimeters.
Selon une caractéristique, la largeur de la section secondaire longiligne présente une valeur comprise entre 1 et 2 millimètres. According to one characteristic, the width of the elongated secondary section has a value of between 1 and 2 millimeters.
Dans une réalisation avantageuse, l'organe inférieur d'ouverture comporte, de part et d'autre d'une partie centrale fixée sur la partie inférieure amovible, une languette de préhension et un bec d'appui adapté pour provoquer une cassure de la ligne inférieure d'amorce de rupture au niveau d'une extrémité de la section principale longiligne. In an advantageous embodiment, the lower opening member comprises, on either side of a central part fixed to the removable lower part, a gripping tongue and a support beak adapted to cause a break in the line lower incipient fracture at one end of the slender main section.
Ainsi, un utilisateur se saisit de la languette de préhension pour l'écarter de la partie inférieure amovible, de sorte que l'organe inférieur d'ouverture forme un levier qui amène le bec d'appui à provoquer une cassure locale de la ligne inférieure d'amorce de rupture, au niveau de cette extrémité de la section principale longiligne, et enfin l'utilisateur exerce une traction sur l'organe inférieur d'ouverture de sorte à poursuivre la déchirure de la ligne inférieure d'amorce de rupture et à dissocier tout ou partie de la partie inférieure amovible par rapport au couvercle inférieure, formant ainsi l'ouverture inférieure de vidange. Thus, a user grabs hold of the grip tab to move it away from the removable lower part, so that the lower opening member forms a lever which causes the support beak to cause a local break in the lower line initiator of rupture, at this end of the slender main section, and finally the user pulls on the lower opening member so as to continue the tearing of the lower line of initiator of rupture and to separate all or part of the removable lower part from the lower cover, thus forming the lower drain opening.
L'invention se rapporte également à un procédé d'ouverture d'une boîte de conserve selon l'invention, une telle boîte de conserve recevant intérieurement des denrées alimentaires baignant dans un jus liquide, ce procédé d'ouverture mettant en œuvre les étapes suivantes : The invention also relates to a method for opening a tin can according to the invention, such a tin can receiving internally foodstuffs bathed in a liquid juice, this opening method implementing the following steps :

[Description détaillée d'exemples de réalisation de l'invention] [Detailed description of exemplary embodiments of the invention]
En références aux Figures 1 à 9, une boîte de conserve 1, selon un exemple de réalisation de l'invention, comprend un corps tubulaire 10 métallique présentant deux extrémités opposées fermées respectivement par un couvercle inférieur 4 et un couvercle supérieur 3. With reference to Figures 1 to 9, a can 1, according to an exemplary embodiment of the invention, comprises a metallic tubular body 10 having two opposite ends closed respectively by a lower lid 4 and an upper lid 3.
Le couvercle supérieur 3 est du type couvercle à ouverture intégrale, et il présente : The top cover 3 is of the cover type with full opening, and it has:
- une partie périphérique 30 en forme de bague, qui est solidarisée à l'une des deux extrémités du corps tubulaire 10, par exemple par sertissage ; et - A peripheral part 30 in the form of a ring, which is secured to one of the two ends of the tubular body 10, for example by crimping; and
- un panneau central d'obturation 31 comprenant une partie supérieure amovible 32 délimitée par une ligne supérieure d'amorce de rupture 33 et équipée d'un organe supérieur d'ouverture 34. - a central closing panel 31 comprising a removable upper part 32 delimited by an upper line of rupture initiation 33 and equipped with an upper opening member 34.
Cette partie supérieure amovible 32 présente une superficie au moins supérieure à 90% d'une superficie du couvercle supérieur 3 pour pouvoir vider la boîte de conserve 1 de denrées alimentaires DA (comme visible sur la Figure 7). This removable upper part 32 has an area at least greater than 90% of an area of the upper cover 3 in order to be able to empty the can 1 of foodstuffs DA (as visible in FIG. 7).
L'organe supérieur d'ouverture 34 est par exemple du type « anneau d'ouverture », et il comporte, de part et d'autre d'une partie centrale fixée sur la partie supérieure amovible 32, une languette de préhension 37 et un bec d'appui 38 adapté pour provoquer une cassure de la ligne supérieure d'amorce de rupture 33. The upper opening member 34 is for example of the “opening ring” type, and it comprises, on either side of a central part fixed to the removable upper part 32, a grip tab 37 and a support nose 38 adapted to cause a break in the upper line of incipient fracture 33.
Aussi, pour séparer ou ouvrir la partie supérieure amovible 32, l'utilisateur manœuvre l'organe supérieur d'ouverture 34 pour déchirer partiellement la ligne supérieure d'amorce de rupture 33, puis il tire sur cet organe supérieur d'ouverture 34 pour poursuivre la déchirure de la ligne supérieure d'amorce de rupture 33 et ainsi ouvrir la partie supérieure amovible 32 suffisamment pour vider la boîte de conserve 1 des denrées alimentaires DA, voire dissocier complètement la partie supérieure amovible 32 par rapport au couvercle supérieur 3. Also, to separate or open the removable upper part 32, the user maneuvers the upper opening member 34 to partially tear the upper line of initiating rupture 33, then he pulls on this upper opening member 34 to continue the tearing of the upper line of incipient rupture 33 and thus open the removable upper part 32 sufficiently to empty the tin can 1 of foodstuffs DA, or even completely dissociate the removable upper part 32 from the upper lid 3.
Le couvercle inférieur 4 présente : The lower cover 4 presents:
- une partie périphérique 40 en forme de bague, qui est solidarisée à l'autre des deux extrémités du corps tubulaire 10, par exemple par sertissage ; et - A peripheral part 40 in the form of a ring, which is secured to the other of the two ends of the tubular body 10, for example by crimping; and
- un panneau central d'obturation 41 comprenant une partie inférieure amovible 42 (non visible sur la Figure 2) délimitée par une ligne inférieure d'amorce de rupture 43 et équipée d'un organe inférieur d'ouverture 44. - a central closing panel 41 comprising a removable lower part 42 (not visible in Figure 2) delimited by a lower line of rupture initiation 43 and equipped with a lower opening member 44.
En référence à la Figure 9, cette partie inférieure amovible 42 présente une section principale longiligne 45 présentant une largeur G1 de valeur inférieure ou égale à 3 millimètres, et par exemple une valeur comprise entre 1 et 2 millimètres, et une longueur L1 de valeur supérieure ou égale à 10 millimètres, et par exemple une valeur comprise entre 10 et 50 millimètres. Referring to Figure 9, this removable lower part 42 has an elongated main section 45 having a width G1 of value less than or equal to 3 millimeters, and for example a value between 1 and 2 millimeters, and a length L1 of greater value or equal to 10 millimeters, and for example a value between 10 and 50 millimeters.
L'organe inférieur d'ouverture 44 est par exemple du type « anneau d'ouverture », et il comporte, de part et d'autre d'une partie centrale fixée sur la partie inférieure amovible 42, une languette de préhension 47 et un bec d'appui 48 adapté pour provoquer une cassure de la ligne inférieure d'amorce de rupture 43 au niveau d'une extrémité de la section principale longiligne 45. The lower opening member 44 is for example of the “opening ring” type, and it comprises, on either side of a central part fixed to the removable lower part 42, a grip tab 47 and a bearing nose 48 adapted to cause a break in the lower line of incipient fracture 43 at the level of one end of the elongated main section 45.
Aussi, pour séparer ou ouvrir la partie inférieure amovible 42, l'utilisateur manœuvre l'organe inférieur d'ouverture 44 pour déchirer partiellement la ligne inférieure d'amorce de rupture 43 au niveau de l'extrémité de la section principale longiligne 45, puis il tire sur cet organe inférieur d'ouverture 44 pour poursuivre la déchirure de la ligne inférieure d'amorce de rupture 43 et ainsi ouvrir la partie inférieure amovible 42 suffisamment pour former dans le couvercle inférieur 4 une ouverture inférieure de vidange 49, pour pouvoir vidanger la boîte de conserve 1 d'un jus liquide JU en préalable de la vider des denrées alimentaires DA. Cette ouverture inférieure de vidange 49 est ainsi délimitée par la ligne inférieure d'amorce de rupture 43. Also, to separate or open the removable lower part 42, the user maneuvers the lower opening member 44 to partially tear the lower line of incipient rupture 43 at the level of the end of the slender main section 45, then he pulls on this lower opening member 44 to continue tearing the lower line of incipient rupture 43 and thus open the removable lower part 42 sufficiently to form in the lower cover 4 a lower drain opening 49, in order to be able to drain the can 1 of a liquid juice JU before emptying it of the foodstuffs DA. This lower drain opening 49 is thus delimited by the lower line of rupture initiation 43.
Dans l'exemple illustré sur les Figures 3, 4 et 9, cette partie inférieure amovible 42 présente également une section secondaire longiligne 46, reliée à la section principale longiligne 45 et s'étendant transversalement vis-à-vis de la section principale longiligne 45, où une telle section secondaire longiligne 46 présente une largeur G2 de valeur inférieure ou égale à 2 millimètres, et par exemple une valeur comprise entre 1 et 2 millimètres, et une longueur L2 de valeur supérieure ou égale à 5 millimètres, et par exemple une valeur comprise entre 5 et 30 millimètres. In the example illustrated in Figures 3, 4 and 9, this removable lower part 42 also has a slender secondary section 46, connected to the slender main section 45 and extending transversely vis-à-vis the slender main section 45 , where such an elongated secondary section 46 has a width G2 with a value less than or equal to 2 millimeters, and for example a value between 1 and 2 millimeters, and a length L2 with a value greater than or equal to 5 millimeters, and for example a value between 5 and 30 millimeters.
Dans cet exemple, la section secondaire longiligne 46 croise en son milieu la section principale longiligne 45 au niveau de l'une de ses extrémités, de sorte que la section principale longiligne 45 et la section secondaire longiligne 46 définissent à elles deux une forme en « T ». Ainsi, l'ouverture inférieure de vidange 49 présente une forme générale en « T ». In this example, the slender secondary section 46 crosses the slender main section 45 in the middle at one of its ends, so that the slender main section 45 and the slender secondary section 46 together define a " T”. Thus, the lower drain opening 49 has a general “T” shape.
Bien entendu, d'autres formes peuvent être prévues pour la partie inférieure amovible 42, et donc pour l'ouverture inférieure de vidange 49, comme par exemple une forme en en « V » (voir Figure 10 à gauche), une forme en « X » (voir Figure 10 au milieu), une forme en « L », une forme en « Y », ou des formes plus complexes comme celle visible en Figure 10 à droite. Il est également à noter que la section principale longiligne 45 et/ou la ou chaque section secondaire longiligne 46 est rectiligne ou incurvée. Of course, other shapes can be provided for the removable lower part 42, and therefore for the lower drain opening 49, such as example a "V" shape (see Figure 10 on the left), an "X" shape (see Figure 10 in the middle), an "L" shape, a "Y" shape, or more complex shapes such as the one visible in Figure 10 on the right. It should also be noted that the elongated main section 45 and/or the or each elongated secondary section 46 is straight or curved.
La suite de la description porte sur le procédé d'ouverture d'une boîte de conserve 1 selon l'invention, cette boîte de conserve 1 recevant intérieurement des denrées alimentaires DA baignant dans un jus liquide JU, ce procédé d'ouverture mettant en œuvre les étapes suivantes : The remainder of the description relates to the process for opening a tin can 1 according to the invention, this tin can 1 internally receiving foodstuffs DA bathed in a liquid juice JU, this opening process implementing the following steps:
- comme illustré sur les Figures 3 et 4, ouverture de la partie inférieure amovible 42 en agissant sur l'organe inférieur d'ouverture 44, formant ainsi dans le couvercle inférieur 4 l'ouverture inférieure de vidange 49 définie au moins par la section principale longiligne 45 et, le cas échéant, par la ou les sections principales longilignes 46 ; - as illustrated in Figures 3 and 4, opening of the removable lower part 42 by acting on the lower opening member 44, thus forming in the lower cover 4 the lower drain opening 49 defined at least by the main section slender 45 and, where appropriate, by the slender main section(s) 46;
- comme illustré sur la Figure 5, ouverture au moins partielle de la partie supérieure amovible 32 en agissant sur l'organe supérieur d'ouverture 34, créant un appel d'air suite à quoi s'opère une vidange du jus liquide JU au travers de l'ouverture inférieure de vidange 49 (comme illustré sur la Figure 6), tout en retenant les denrées alimentaires DA ; et - as illustrated in Figure 5, at least partial opening of the removable upper part 32 by acting on the upper opening member 34, creating a call for air following which the liquid juice JU is drained through of the lower drain opening 49 (as illustrated in Figure 6), while retaining the foodstuffs DA; and
- une fois le jus liquide JU purgé, ouverture complète (ou quasi-complète) de la partie inférieure amovible 42 afin de récupérer les denrées alimentaires DA vidées du jus liquide JU, comme illustré sur la Figure 7. - once the liquid juice JU has been purged, complete (or almost complete) opening of the removable lower part 42 in order to recover the foodstuffs DA emptied of the liquid juice JU, as illustrated in Figure 7.
