Abstract

The vessel closure has a base (4) fixed to the vessel (1) and containing one or more apertures (9). A cover (11) can be secured to it (6,7,8) in two positions, forming a chamber (16) allowing fitting of an elastic disc (17) over the apertures. The cover has one or more apertures (14), also an internal protruding edge (15), which, in one of the positions, bears against the disc to form a seal. There are one or more holes (18) in the disc, inside the edge (15) when the cover is in the sealing position. A filter (10,30) can be provided on the base.

Description

La présente invention a pour objet un dispositif d'obturation à action rapide pour récipients. The present invention relates to a fast-acting closure device for containers.

L'invention est relative à un dispositif d'obturation applicable à un récipient de préférence flexible, à travers lequel on peut, en vue d'assurer une conservation optimale du produit contenu dans le récipient, faire le vide dans ce dernier puis y introduire un gaz inerte et enfin le fermer. The invention relates to a closure device applicable to a preferably flexible container, through which it is possible, in order to ensure optimal preservation of the product contained in the container, to evacuate the latter and then introduce a inert gas and finally close it.

te Brevet italien NO 989 172 au nom du Déposant de la présente Demande, décrit une valve permettant de faire le vide dans un récipient, puis, une fois le vide atteint, de fermer la valve d'une manière étanche. La valve en question est une valve unidirectionnelle, de sorte qu'il est impossible d'introduire, à travers cette valve, un gaz inerte dans le récipient, comme cela est exigé dans plusieurs applications.Ladite valve comprend un corps perforé de base, relié au récipient par une bride ou collerette et pourvu de parties alternativement en saillie et en creux avec lesquelles un couvercle perforé peut venir instantanément en prise, dans deux positions différentes, ledit couvercle et ledit corps délimitant entre eux une chambre servant de logement à un disque élastique susceptible d'obturer le trou percé dans ledit corps. lorsque le couvercle est dans l'une de ces positions, la valve exerce une action unidirectionnelle, en ce sens qu'elle permet de faire le vide dans le récipient mais ne permet pas d'introduire un gaz, tandis que dans l'autre position du couvercle, pour laquelle ce dernier est pressé à fond sur le corps de base, les gaz ne peuvent pas pénétrer dans le récipient ou en sortir. te Italian Patent NO 989 172 in the name of the Applicant of this Application, describes a valve making it possible to create a vacuum in a container, then, once the vacuum is reached, to close the valve in a sealed manner. The valve in question is a one-way valve, so that it is impossible to introduce, through this valve, an inert gas into the container, as is required in several applications. Said valve comprises a basic perforated body, connected to the container by a flange or flange and provided with alternately projecting and recessed parts with which a perforated cover can instantly come into engagement, in two different positions, said cover and said body delimiting between them a chamber serving as a housing for an elastic disc capable of closing the hole drilled in said body. when the cover is in one of these positions, the valve exerts a unidirectional action, in the sense that it makes it possible to create a vacuum in the container but does not make it possible to introduce a gas, while in the other position of the cover, for which the latter is pressed all the way onto the base body, the gases cannot enter or leave the container.

Le but de la présente invention est de réaliser un dispositif qui dérive de la valve précitée, mais qui soit établi pour permettre l'introduction d'un gaz inerte dans le récipient associé, après que l'on y ait fait le vide. The object of the present invention is to provide a device which derives from the aforementioned valve, but which is established to allow the introduction of an inert gas into the associated container, after a vacuum has been created there.

Selon l'invention, le dispositif en question se différencie de la valve antérieurement connue, par le fait que le disque élastique est muni d'un trou en son milieu, de telle façon que pour une position du couvercle, des gaz puissent pénétrer ou sortir du récipient, tandis que pour l'autre position du couvercle, cette condition est irréalisable. Ainsi, pour la première position du couvercle, il devient possible, en faisant appel à un organe en forme de cloche qui, au moyen d'une soupape, peut être mis sélectivement en liaison avec une source de vide ou une source de gaz sous pression, de créer d'abord le vide dans le récipient associé et d'y introduire ensuite un gaz de protection inerte. According to the invention, the device in question differs from the previously known valve, in that the elastic disc is provided with a hole in the middle, so that for a position of the cover, gases can penetrate or leave of the container, while for the other position of the lid, this condition is not possible. Thus, for the first position of the cover, it becomes possible, by using a bell-shaped member which, by means of a valve, can be selectively connected to a source of vacuum or a source of gas under pressure. , first create a vacuum in the associated container and then introduce an inert protective gas.

Ces caractéristiques et d'autres encore ressortiront de la suite de la description. These characteristics and others will emerge from the following description.

Pour bien fixer l'objet de l'invention, sans toutefois le limiter, aux figures du dessin annexé
la figure 1 est une vue en coupe verticale du dispositif selon l'invention ; le dispositif est illustré dans la position ouverte pour laquelle il est possible, au moyen d'une ventouse schématisée par des traits interrompus, de faire le vide dans un récipient (auquel le dispositif est associé), puis d'y introduire un gaz inerte ;
la figure 2 est une vue semblable à la figure i illustrant ledit dispositif dans la position d'obturation.To clearly define the object of the invention, without however limiting it, to the figures of the appended drawing
Figure 1 is a vertical sectional view of the device according to the invention; the device is illustrated in the open position for which it is possible, by means of a suction cup shown diagrammatically by broken lines, to create a vacuum in a container (with which the device is associated), then to introduce an inert gas there;
Figure 2 is a view similar to Figure i illustrating said device in the closed position.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative en se référant aux exemples de réalisation illustrés aux figures du dessin. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner with reference to the exemplary embodiments illustrated in the figures of the drawing.

On a référencé par (1) une paroi d'un récipient flexible tel par exemple un sachet ou une enveloppe, en matériau stratifié, dont la couche intérieure au moins, est en matière plastique thermosoudable. la paroi (1) est percée d'un trou (2) et tout autour du bord d'extrémité de ce dernier, est fixée par thermosoudage, une collerette (3) faisant partie du corps de base (4),en plastique thermosoudable, du dispositif selon l'invention. le corps de base (4) comprend une partie cylindrique faisant saillie au-dessus de l'ouverture (2) du récipient et qui est pourvue extérieurement de deux bourelets ou renflements annulaires (6, 7) que sépare une rainure (8).Te corps de base (4) est pourvu en outre, en son milieu, d'un trou (9) et au niveau de ce dernier, d'un croisillon ou d'un système d'éléments disposés en étoile (10) ayant pour fonction de retenir les particules de produit susceptibles d'être aspirées et dont la pénétration dans le dispositif pourrait être préjudiciable à son fonctionnement. Reference has been made to (1) a wall of a flexible container such as, for example, a sachet or an envelope, of laminated material, of which the inner layer at least, is of heat-sealable plastic. the wall (1) is pierced with a hole (2) and all around the end edge of the latter, is fixed by heat sealing, a flange (3) forming part of the base body (4), made of heat sealable plastic, of the device according to the invention. the base body (4) comprises a cylindrical part projecting above the opening (2) of the container and which is provided externally with two annular bulges or bulges (6, 7) which are separated by a groove (8). base body (4) is further provided, in the middle, with a hole (9) and at the level of this, a cross or a system of elements arranged in a star (10) having the function to retain particles of product which can be sucked in and whose penetration into the device could be detrimental to its operation.

le dispositif selon l'invention comporte aussi un couvercle (11) en matière plastique élastiquement déformable, muni d'un tablier ou jupe (12) dont la paroi intérieure est pourvue de renflements ou bourrelets annulaires. Te bourrelet inférieur (13) de ladite jupe coopère avec la rainure (8) lorsque le couvercle est dans la position de la figure 1. lorsque ce dernier est amené dans la position représentée figure 2, ledit bourrelet (13) vient en prise, par déformation élastique, sous le bourrelet (7) du corps de base (4).  the device according to the invention also comprises a cover (11) made of elastically deformable plastic, provided with an apron or skirt (12), the inner wall of which is provided with annular bulges or beads. Te lower bead (13) of said skirt cooperates with the groove (8) when the cover is in the position of FIG. 1. When the latter is brought into the position shown in FIG. 2, said bead (13) engages, by elastic deformation, under the bead (7) of the base body (4).

La partie supérieure du couvercle (ii) est munie de trous (14) et présente en outre un rebord continu (15) et une saillie conique (19) dirigés vers le bas. The upper part of the cover (ii) is provided with holes (14) and further has a continuous rim (15) and a conical projection (19) directed downwards.

Te couvercle (71) et le corps de base (4) délimitent entre eux, une chambre (16) dans laquelle est disposé un disque flexible (17) en caoutchouc, présentant dans sa partie centrale, un trou (18). The cover (71) and the base body (4) define between them, a chamber (16) in which is disposed a flexible rubber disc (17), having in its central part, a hole (18).

lorsque les produits à protéger sont des granulés fins, on les empêche de pénétrer dans le dispositif dont ils pourraient affecter le fonctionnement, au moyen d'une feuille ou d'un disque de papier filtrant (30) fixé sur le dessus du corps de base (4), par exemple par scellement à chaud ou à l'aide d'un adhésif. when the products to be protected are fine granules, they are prevented from entering the device, which they could affect the operation, by means of a sheet or a disc of filter paper (30) fixed on the top of the base body (4), for example by heat sealing or using an adhesive.

Après avoir introduit le produit dans le récipient puis fermé celui-ci d'une manière étanche, par exemple au moyen d'un scellement à chaud, l'utilisateur applique sur le dispositif, manuellement par exemple, un élément en forme de cloche (20) relié à une soupape "V" à travers un tube, par exemple un tube flexible (21). Cette cloche rigide, est pourvue de garnitures (31) et équipée d'un piston (32) dont la tige (33) traverse une ouverture appropriée, des garnitures d'étanchéité (34) étant également prd- vues. Par l'intermédiaire de la soupape "V", l'usager met la cloche en communication avec un conduit (22) relié à une source de vide,d'un type approprié quelconque, non représentée.Ainsi l'air est aspiré du récipient par les trous (9, 18 et 14) du dispositif, ces trous étant à ce moment tous ouverts. ;'opération d'évacuation étant achevée, la soupape "V" est amenée dans une position pour laquelle la cloche (20) est mise en liaison avec une source de gaz inerte sous pression (non représentée), à travers un conduit (23). After having introduced the product into the container and then closed the latter in a sealed manner, for example by means of a heat seal, the user applies to the device, manually for example, a bell-shaped element (20 ) connected to a valve "V" through a tube, for example a flexible tube (21). This rigid bell is provided with linings (31) and equipped with a piston (32), the rod (33) of which passes through a suitable opening, sealing linings (34) also being provided. Via the valve "V", the user puts the bell in communication with a duct (22) connected to a vacuum source, of any suitable type, not shown. Thus the air is drawn from the container by the holes (9, 18 and 14) of the device, these holes being at this time all open. the evacuation operation being completed, the valve "V" is brought into a position for which the bell (20) is connected to a source of pressurized inert gas (not shown), through a conduit (23) .

En conséquence, le gaz inerte pénètre dans le récipient par les trous (14, 18 et 9) qui servent alors d'arrivées de gaz. ;'opéra- tion de chargement en gaz étant terminée, l'utilisateur exerce, directement ou indirectement, par actionnement du piston (32) monté dans la cloche (20), une pression dans le sens de la flèche (A), sur le couvercle (11) qui, en conséquence, est amené instantanément dans la position de la figure 2, pour laquelle le bourrelet (13) du couvercle est en prise, par déformation élastique, sous le bourrelet (7) du corps de base (4), le rebord annulaire (15) s'étant enfoncé dans le disque élastique (17), obture le trou (18) dudit disque, supprimant ainsi toute liaison entre le récipient fermé d'une manière étanche, et l'extérieur, ledit récipient pouvant être soumis à d'autres opérations ultérieures,si nécessaire. le piston (32) peut entre, soit actionné à la main à l'encontre de l'action d'un ressort, soit commandé au moyen d'un vérin pneumatique, d'un électro-aimant ou d'une came.Consequently, the inert gas enters the container through the holes (14, 18 and 9) which then serve as gas inlets. the gas loading operation being completed, the user exerts, directly or indirectly, by actuating the piston (32) mounted in the bell (20), pressing in the direction of the arrow (A), on the cover (11) which, consequently, is brought instantaneously into the position of FIG. 2, for which the bead (13) of the cover is engaged, by elastic deformation, under the bead (7) of the base body (4) , the annular rim (15) having sunk into the elastic disc (17), closes the hole (18) of said disc, thus eliminating any connection between the container closed in a sealed manner, and the outside, said container possibly be subjected to other subsequent operations, if necessary. the piston (32) can either be actuated by hand against the action of a spring, or controlled by means of a pneumatic cylinder, an electromagnet or a cam.

L'invention ne se limite aucunement à celui de ces modes d'application, non plus qu'à ceux des modes de réalisation de ces diverses parties ayant plus spécialement été indiqués ; elle en embrasse au contraire toutes les variantes.  The invention is in no way limited to that of these modes of application, nor to those of the embodiments of these various parts which have been more particularly indicated; on the contrary, it embraces all its variants.
