Abstract
Description
La présente invention concerne un nouveau conteneur étanche pour produits divers et à ouverture manuelle qui peut être avantageusement fabriqué en matière plastique et qui de plus est inviolable. The present invention relates to a new sealed container for various products and with manual opening which can advantageously be made of plastic and which is also tamper-proof.
Le conteneur de l'invention permet aussi le cas échéant d'amener la stérilisation des produits contenus. The container of the invention also makes it possible, if necessary, to bring about the sterilization of the products contained.
En outre le conteneur de l'invention comporte un couvercle pouvant permettre sa réutilisation après une première ouverture. In addition, the container of the invention has a cover which can allow its reuse after a first opening.
La technique antérieure a déjà fait connaitre- des conteneurs comportant une partie en forme de botte, un couvercle et des moyens pouvant etre déchirés pour séparer le couvercle de la boîte; c'est le cas des réalisations décrites dans le FR-A-i 335 350 , le
US-A-2 941 660, le US-A-3 463 347 ou le FR-A-2 409 202.The prior art has already made known containers containing a boot-shaped part, a cover and means which can be torn apart to separate the cover from the box; this is the case of the embodiments described in FR-Ai 335 350, the
US-A-2,941,660, US-A-3,463,347 or FR-A-2,409,202.
Il est apparu que la fermeture étanche et la facilité d'ouverture ultérieure présentent des difficultés, soit du fait de la flexibilité de la matière constitutive de la botte et du couvercle, soit du fait que la matière est plus ou moins rendue cassante lorsqu'elle a vieilli et cela notamment lorsque le produit qu'elle contient a été stérilisé car la stérilisation entraîne un vieillissement accéléré de la matière constitutive de la botte et du couvercle. It appeared that the tight closure and the ease of subsequent opening present difficulties, either because of the flexibility of the material of the boot and of the cover, or of the fact that the material is more or less brittle when it has aged and this especially when the product it contains has been sterilized because sterilization results in accelerated aging of the material of the boot and of the cover.
La présente invention remédie aux inconvénients ci-dessus. The present invention overcomes the above drawbacks.
Conformément à l'invention, le conteneur à ouverture manuelle pour produits divers, comportant une partie en forme de boîte reliée par une bride à un couvercle prenant appui sur la bride et soudé à celleci, et des organes de rupture prévus entre le couvercle et la bride de la partie en forme de boîte, est caractérisé en ce qu'une gorge est délimitée dans la bride contre un côté de la paroi périphérique externe de la partie en forme de boite, en ce qu'un rebord annulaire est prévu à la base du couvercle, en ce qu'une rainure périphérique est prévue dans le rebord annulaire pour correspondre au moins en partie à la gorge et en ce que la partie de la bride et du rebord annulaire se trouvant au-delà de la gorge et de la rainure périphérique sont réunis de façon étanche et indémontable. According to the invention, the container with manual opening for various products, comprising a box-shaped part connected by a flange to a cover bearing on the flange and welded thereto, and rupture members provided between the cover and the flange of the box-shaped part, is characterized in that a groove is delimited in the flange against one side of the external peripheral wall of the box-shaped part, in that an annular flange is provided at the base of the cover, in that a peripheral groove is provided in the annular rim to correspond at least in part to the groove and in that the part of the flange and the annular rim lying beyond the groove and the groove device are joined together in a sealed and non-removable manner.
L'objet de l'invention est représenté, à titre d'exemple aux dessins annexés auxquels se réfère la description qui suit. The object of the invention is shown, by way of example in the appended drawings to which the following description refers.
La fig. 1 est une coupe-élévation d'un conteneur conforme à l'invention. Fig. 1 is a sectional elevation of a container according to the invention.
Les fig. 2 et 3 sont des coupes-élévations partielles à plus grande échelle montrant une variante et illustrant deux positions caractéristiques de la partie formant boîte et du couvercle qui la recouvre. Figs. 2 and 3 are partial sectional elevations on a larger scale showing a variant and illustrating two characteristic positions of the box part and of the cover which covers it.
La fig. 4 est une élévation schématique illustrant la façon de procéder pour une première ouverture du conteneur. Fig. 4 is a schematic elevation illustrating the procedure for a first opening of the container.
La fig. 5 est une coupe-élévation, analogue à la fig. 3, illustrant un développement de l'invention. Fig. 5 is a sectional elevation, similar to FIG. 3, illustrating a development of the invention.
La fig. 6 est une vue prise sensiblement suivant la ligne VI-VI de la fig. 5. Fig. 6 is a view taken substantially along line VI-VI of FIG. 5.
Le conteneur illustré aux dessins comporte une partie 1 formant boîte et délimitant un fond 2 duquel fait saillie une paroi périphérique montante 3 formant extérieurement et à distance de son bord supérieur 4 une bride périphérique 5. The container illustrated in the drawings comprises a part 1 forming a box and delimiting a bottom 2 from which protrudes a rising peripheral wall 3 forming externally and at a distance from its upper edge 4 a peripheral flange 5.
Le segment 6, qui s'étend depuis le bord supérieur 4 jusqu'au-dessus de la bride 5 sert au guidage du bord vertical 7 d'un couvercle 8. Le bord vertical 7 du couvercle délimite, à sa partie basse, un rebord annulaire 9 qui correspond à la bride 5 du corps. The segment 6, which extends from the upper edge 4 to above the flange 5 is used for guiding the vertical edge 7 of a cover 8. The vertical edge 7 of the cover delimits, at its lower part, a rim annular 9 which corresponds to the flange 5 of the body.
Tant la boîte 1 que le couvercle 8 sont fabriqués en une matière plastique, thermoplastique soudable et pouvait supporter une température élevée de stérilisation, c'est-à-dire au moins 105 C et de pré férence environ 1300C. De nombreuses matières plastiques peuvent être utilisées pour satisfaire aux conditions ci-dessus, par exemple le polypropylène, des polychiorures de vins, des polyamides, des poLyacétals, etc.Le polypropylène est particulièrement avantayeux, tant au point de vue prix de revient que des résultats qu'il procure, particulièrement lorsque le conteneur a subi une stérilisation dans la gamme des températures indiquées ci-dessus, au cours de laquelle cette matière, ainsi que la plupart des autres matières mentionnées, subit un vieillissement accéléré tendant à augmenter la durete. Both the box 1 and the cover 8 are made of a plastic, weldable thermoplastic and could withstand a high sterilization temperature, that is to say at least 105 ° C. and preferably about 1300 ° C. Many plastics can be used to satisfy the above conditions, for example polypropylene, wine polychiorides, polyamides, polyacetals, etc. Polypropylene is particularly advantageous, both in terms of cost and results that it provides, particularly when the container has undergone sterilization in the range of temperatures indicated above, during which this material, as well as most of the other materials mentioned, undergoes accelerated aging tending to increase the hardness.
La bride 5 présente une gorge 10- dont le côté 1 Od est formé par la paroi externe du corps 1 et dont le côté 10b est avantageusement vertical ou légèrement en contre-dépouille. The flange 5 has a groove 10- whose side 1 Od is formed by the external wall of the body 1 and whose side 10b is advantageously vertical or slightly undercut.
Au-deld de la gorge 10, la bride 5 délimite un anneau 11 dont le dessus est par exemple plan. La bride 5 est conformée un peu à la manière d'une console pour que l'anneau 11 soit aussi rigide que possible, en particulier sous l'effet de charges verticales qui peuvent lui être appliquées. Beyond the groove 10, the flange 5 delimits a ring 11 the top of which is for example flat. The flange 5 is shaped somewhat like a console so that the ring 11 is as rigid as possible, in particular under the effect of vertical loads which can be applied to it.
Le rebord annulaire 9 du couvercle 7 délimite une rainure 12 sur toute sa périphérie. Un côté de la rainure 12 est délimité par le côté extérieur du bord vertical 7 du couvercle, lorsque ce bord tombé présente la même épaisseur en section que celle du corps 1 de façon que la rainure 12 se trouve au dessus du bord 10b de la gorge 10. The annular rim 9 of the cover 7 defines a groove 12 over its entire periphery. One side of the groove 12 is delimited by the outer side of the vertical edge 7 of the cover, when this fallen edge has the same thickness in section as that of the body 1 so that the groove 12 is located above the edge 10b of the groove 10.
Au-delà de la rainure 12, le rebord annulaire 9 délimite un anneau 13 dont le diamètre extérieur correspond à celui de l'anneau 11. Beyond the groove 12, the annular rim 9 delimits a ring 13 whose outside diameter corresponds to that of the ring 11.
Comme le montre la fig. 1, le fond du couvercle 8 est séparé du bord supérieur 4 par un intervalle pour ne pas venir en contact ensemble lorsque les anneaux 11 et le rebord annulaire 13 sont appliqués l'un sur l'autre. As shown in fig. 1, the bottom of the cover 8 is separated from the upper edge 4 by an interval so as not to come into contact together when the rings 11 and the annular rim 13 are applied one on the other.
Lorsque la partie formant boîte décrite cidessus a reçu le produit qu'elle doit contenir et que le couvercle a été mis en place, le rebord annulaire 13 est soudé par vibration, notamment par ultrasons au moyen de sonotrodes, sur l'anneau 11. When the box-forming part described above has received the product which it must contain and the cover has been put in place, the annular rim 13 is welded by vibration, in particular by ultrasound by means of sonotrodes, to the ring 11.
Les fig. 2 et 3 illustrent une variante dans laquelle la bride 5-est conformée un peu à la manière d'une console pour que l'anneau 11 soit aussi rigide que possible, en particulier sous l'effort de charges verticales qui peuvent lui être appliquées. Figs. 2 and 3 illustrate a variant in which the flange 5 is shaped a little like a console so that the ring 11 is as rigid as possible, in particular under the force of vertical loads which can be applied to it.
En outre l'anneau 13 présente une nervure 14 formant concentrateur d'énergie facilitant l'exécution de la soudure 16.In addition, the ring 13 has a rib 14 forming an energy concentrator facilitating the execution of the weld 16.
Les fig. 2 et 3 montrent en outre immédiatement à l'extérieur de la rainure 10, un couteau 16 qui est formé sur toute la périphérie de l'anneau 11 par une rainure 17 en V. Le dessin montre alors que le couteau 16 correspond à la rainure 12. Figs. 2 and 3 also show immediately outside the groove 10, a knife 16 which is formed over the entire periphery of the ring 11 by a V-shaped groove 17. The drawing then shows that the knife 16 corresponds to the groove 12.
Lorsqu'on désire ouvrir le conteneur réalisé comme à la fig. 1 ou aux fig. 2 et 3, on le saisit, par exemple entre le pouce et l'index, et on exerce sur une partie du couvercle une force f1 (fig. 4) qui est appliquée sur une faible longueur seulement de la périphérie. When you want to open the container made as in fig. 1 or in figs. 2 and 3, it is grasped, for example between the thumb and the index finger, and a force f1 (fig. 4) is applied to a part of the cover which is applied over only a short length of the periphery.
De cette manière, même si la force f1 n'est pas très élevée elle engendre au niveau du bord 1Ob de la rainure ou au niveau du couteau 16 un effort pratiquement ponctuel qui produit la rupture du segment 18 (fig. 3) formant le fond de la rainure 12.In this way, even if the force f1 is not very high, it generates at the edge 10b of the groove or at the level of the knife 16 a practically punctual force which produces the rupture of the segment 18 (fig. 3) forming the bottom. of the groove 12.
L'opérateur exerce ensuite une force en f2 (fig. 4), ce qui a pour effet de continuer à rompre le segment 18. The operator then exerts a force at f2 (fig. 4), which has the effect of continuing to break the segment 18.
La fig. 4 montre la déformation progressive qu'il est possible de donner au couvercle 8 pour produire la rupture décrite ci-dessus. On procède ensuite de proche en proche, c'est-d-dire qu'un effort suivant est exercé en f et ainsi de suite. Fig. 4 shows the progressive deformation that it is possible to give to the cover 8 to produce the rupture described above. We then proceed step by step, that is to say that a next effort is exerted at f and so on.
Lorsque l'ensemble du segment 18 a été rompu, ce qui est facilité par le couteau 16 lorsqu'il existe, le couvercle 8 peut être extrait par arrachement ou rotation combinée avec un arrachement. Pour faciliter la préhension du couvercle 7, il est avantageux que celui-ci présente des aspérités ou bossages qui ne sont pas représentées pour ne pas compliquer le dessin. When the entire segment 18 has been broken, which is facilitated by the knife 16 when it exists, the cover 8 can be removed by tearing or rotation combined with a tearing. To facilitate gripping of the cover 7, it is advantageous for the latter to have roughness or bosses which are not shown so as not to complicate the drawing.
Le retrait du couvercle donne évidemment accès à l'intérieur du conteneur qui peut ensuite être refermé puisque le couvercle peut être remis en place et qu'il peut être engagé éventuellement jusqu'au fond de la gorge 10 en assurant ainsi une très bonne fermeture. Le couvercle est capable de supporter des efforts de compression relativement élevés sans risque de rupture du segment 18 bien qu'il serve à rompre ce segment. En effet, l'ouverture par le moyen décrit n'est possible qu'en exerçant une force pratiquement ponctuelle et en appliquant cette force progressivement sur toute la périphérie du couvercle. Par suite une force s'exerçant sur l'ensemble du couvercle devrait être très élevée pour rompre l'ensemble du segment 18.En effet, une telle force répartie uniformément, ou à peu près uniformément, n'aurait pas tendance à produire la courbe 19, schématisée à la fig. 4, qui seule permet la création de la force ponctuelle produisant la première rupture. The removal of the cover obviously gives access to the interior of the container which can then be closed since the cover can be replaced and that it can possibly be engaged up to the bottom of the groove 10 thereby ensuring a very good closure. The cover is capable of withstanding relatively high compressive forces without risk of breaking the segment 18 although it serves to break this segment. Indeed, the opening by the means described is only possible by exerting a practically punctual force and by applying this force gradually over the entire periphery of the cover. Consequently, a force exerted on the whole of the cover should be very high to break the whole of the segment 18. Indeed, such a force distributed uniformly, or almost uniformly, would not tend to produce the curve 19, shown diagrammatically in FIG. 4, which alone allows the creation of the point force producing the first rupture.
Bien que la présence de l'anneau 11 et du rebord annulaire ne soit pas gênante dans la plupart des cas, après une première ouverture du conteneur, il est possible, le cas échéant, d'éliminer cet anneau et ce rebord. Pour cela, comme l'illustrent les fig. 5 et 6, une fente arquée 19 est formée en dessous de l'an neau 11 pour s'étendre jusqu'à une rainure 20 formée en dessous de l'anneau 11 contre la paroi externe montante 3. La rainure 20 délimite avec le fond de la gorge 10 un segment 21 qui peut être facilement rompu lorsque le couvercle est retiré et qu'on exerce une pression ou une traction sur la partie saillante en porte-à-faux que constituent l'anneau 11 et le rebord annulaire 13 qui sont soudés entre eux. Although the presence of the ring 11 and the annular rim is not troublesome in most cases, after a first opening of the container, it is possible, if necessary, to eliminate this ring and this rim. For this, as illustrated in figs. 5 and 6, an arcuate slot 19 is formed below the ring 11 to extend to a groove 20 formed below the ring 11 against the rising external wall 3. The groove 20 delimits with the bottom from the groove 10 a segment 21 which can be easily broken when the cover is removed and pressure or traction is exerted on the cantilever projecting part constituted by the ring 11 and the annular flange 13 which are welded together.
