   La fermeture d'un récipient en matière thermoplastique, décrite dans le brevet N  520.327 du demandeur, est obtenue au moyen d'un couvercle à rabattement appliqué,avec interposition d'un anneau de joint et en soudant le bord du couvercle en différents endroits sur le récipient, et l'étanchéité de la fermeture est assurée par cet anneau et par la dépression qui s'établit après le chauffage du récipient fermé.. 



   Le présent additif a pour but de permettre de faire le vide dans un tel récipient après sa fermeture,' grâce à un disposi- tif spécial, dont est pourvu son couvercle. 

 <Desc/Clms Page number 2> 

 



   Conformément à l'invention, le couvercle à rabattement du récipient comporte un trou, dans lequel est placée une soupape, sus- ceptible de   l*obturer   de façon étanche, par la création de la   dépres.   sion dans le récipient et d'être soulevée librement par simple aspi- ration. 



   Selon un mode de réalisation, la soupape est constituée par un bout de tuyau de caoutchouc, dans lequel est engagé à force un rivet creux borgne formant bouchon, 
On comprendra que, avec une pompe à vide, on pourra faire le vide dans le récipient en aspirant l'air contenu à travers l'espace annulaire entre la soupape et son siège, c'est-à-dire l'orifice du trou prévu dans le couvercle, ce qui provoquera simultanément la le- vée de la soupape, et que, la dépression voulue ayant été obtenue,la soupape se colle sur son siège sous l'effet de la pression atmosphé- rique extérieure. 



   L'invention sera mieux comprise en regard du dessin annexé, dans lequel : la fig.1 monte le couvercle du. récipient fermé et la soupape ouverte; la fig.2 est une vue analogue, après la création de la dé- pression, la soupape étant en position d'application étanche sur l'orifice du trou. 



   Un récipient 1 de forme quelconque appropriée est muni à une ' certaine distance du bord 2 de son orifice et sur sa paroi extérieure d'un rebord 1 sur son pourtour. Le couvercle 4. conformément au bre-   vet N    520.327 du demandeur, présente un bord   rabattu .5   avec un re- bord circulaire 6 et, à la naissance du bord, une cannelure 1 desti- née à recevoir un anneau en caoutchouc formant joint   étanche.3,!.   



   Dans la partie centrale 8 du couvercle, est prévu, conformé- ment à l'additif,un trou 9, destiné à recevoir librement un bouchon.' 
10. constitué par une patie métallique 11, de forme conique creuse, sous la forme par exemple d'un rivet creux   borgne,insérée'dans   un   boutée tuyau de caoutchouc 12.

 <Desc/Clms Page number 3> 

 
Ce bouchon 10 constitue une soupape reposant librement sur l'orifice du trou   .   



   La soupape est soulevée par aspiration de la pompe utilisée pour créer la dépression voulue dans le récipient, au cours de son opération, et elle retombe ensuite librement en formant joint étanche, sous la différence de pression de la pression atmosphérique extérieu- re et de la dépression à l'intérieur du récipient. 



   Ce dispositif de soupape, qui peut rester à demeure sur le couvercle, peut être exécuté différemment, la pièce 11 pouvant d'ail- leurs être en une matière quelconque. 



   - REVENDICATIONS - 
1  - Dispositif permettant la création de la dépression à l'intérieur d'un récipient pourvu de l'organe de ferme- ture tel que couvercle à rabattement -conformément au brevet N  520.327, constitué par une soupape montée dans un trou pratiqué dans le cou- vercle, et susceptible de s'y déplacer librement, de façon à l'ob- turer de façon étanche par la création de la dépression dans le ré- cipient. 

**ATTENTION** fin du champ DESC peut contenir debut de CLMS **.

   The closure of a thermoplastic container, described in the patent N 520.327 of the applicant, is obtained by means of an applied hinged cover, with the interposition of a gasket ring and by welding the edge of the cover in different places on the container, and the tightness of the closure is ensured by this ring and by the vacuum which is established after the heating of the closed container.



   The object of the present additive is to make it possible to create a vacuum in such a container after it has been closed, by means of a special device, with which its cover is provided.

 <Desc / Clms Page number 2>

 



   According to the invention, the hinged lid of the container has a hole, in which is placed a valve, capable of sealing it off by the creation of the depression. in the container and to be lifted freely by simple suction.



   According to one embodiment, the valve is formed by a piece of rubber pipe, in which is forcibly engaged a hollow blind rivet forming a stopper,
It will be understood that, with a vacuum pump, it will be possible to create a vacuum in the container by sucking the air contained through the annular space between the valve and its seat, that is to say the orifice of the provided hole. in the cover, which will simultaneously cause the valve to lift, and that, the desired vacuum having been obtained, the valve sticks to its seat under the effect of the external atmospheric pressure.



   The invention will be better understood with reference to the accompanying drawing, in which: FIG. 1 mounts the cover of. closed container and open valve; FIG. 2 is a similar view, after the creation of the depression, the valve being in the sealed application position on the orifice of the hole.



   A container 1 of any suitable shape is provided at a certain distance from the edge 2 of its orifice and on its outer wall with a rim 1 around its periphery. The cover 4. in accordance with patent N 520.327 of the applicant, has a folded edge .5 with a circular rim 6 and, at the start of the edge, a groove 1 intended to receive a rubber ring forming a tight seal. .3,!.



   In the central part 8 of the cover, there is provided, in accordance with the additive, a hole 9, intended to freely receive a stopper.
10. consisting of a metal plate 11, of hollow conical shape, in the form for example of a hollow blind rivet, inserted into a rubber pipe end 12.

This plug 10 constitutes a valve resting freely on the orifice of the hole.



   The valve is lifted by suction from the pump used to create the desired vacuum in the vessel, during its operation, and it then drops freely, forming a tight seal, under the pressure difference of the outside atmospheric pressure and the pressure. depression inside the container.



   This valve device, which can remain permanently on the cover, can be made differently, the part 11 being able, moreover, to be of any material.



   - CLAIMS -
1 - Device allowing the creation of the vacuum inside a container provided with the closing member such as a hinged cover - in accordance with patent N 520.327, consisting of a valve mounted in a hole in the neck - circle, and capable of moving freely therein, so as to seal it off by creating a vacuum in the receptacle.

** ATTENTION ** end of DESC field can contain start of CLMS **.
