Description

       

   <Desc/Clms Page number 1> 
 



  Couvercle pour boites et récipients de tous genres,       en particulier pour bottes à conserve   @   
La présente invention concerne un couvercle qui est destiné de préférence-à fermer de façon étanche à l'air des boites à conserve utilisées. 



   Jusqu'à présent les anciennes boîtes à conserve qui devaient être utilisées à nouveau étaient découpées par des machines et fermées de nouveau par des machines d'obtura- tion. Dans cette façon de procéder, la capacité de la boite à conserve découpée devient plus petite. Dans le ménage on ne dispose par de semblables machines de découpage et de fermeture, de sorte que les boites à conserve ouvertes doi- vent être rejetées. 



   Suivant la présente invention, les boites à conserve ouvertes sont fermées par un couvercle qui est enfoncé sans -aucun moyen accessoire, à la main, sur la boite et ferme celle-ci immédiatement de façon étanche à l'air. Cette fermeture hermétique est obtenue par le fait que dans une rainure annulaire du fond du couvercle est posé un anneau 

 <Desc/Clms Page number 2> 

 de caoutchouc d'environ 3 à 6 mm. d'épaisseur et que la paroi périphérique cylindrique du couvercle est   pourvue''de   languettes ou de pattes formant ressorts qui, lors de   l'ap-   plication du couvercle, s'adaptent en-dessous du bord épais- si de la boîte à conserve et maintiennent le couvercle en position de façon sûre. La boite remplie au préalable peut alors être soumise à une cuisson sans que le couvercle saute. 



   Pour assurer dans chaque cas un' engagement des pattes de façon sûre, les coins des pattes peuvent être recourbés vers l'intérieur du couvercle. En outre, le fond du couver- cle possède une partie centrale plane entourée d'un bourre- let et qui se raccorde à une partie en tronc de cône, ainsi que différents renfoncements annulaires de sorte qu'il peut se bomber vers le haut sous l'effet de la pression prenant naissance lors de la cuisson. 



   Le dessin représente à titre d'exemple une forme de réalisation du nouveau couvercle. 



   La fig. 1 est une vue du dessus du couvercle. 



   La fig. 2 est une coupe verticale dans le couvercle. 



   La fig. 3 est une vue en perspective à plus grande échelle de la patte. 



   La fig. 4 montre une boîte à conserve fermée au moyen du nouveau couvercle- 
Dans la forme de réalisation du couvercle suivant les figs. 1 et 2, le fond consiste en une partie centrale plane 1 qui est délimitée par un bourrelet ou un renfoncement 2 refoulé vers l'intérieur du couvercle. Le renfoncement an-   nulaire 2   se raccorde à une partie en tronc de   cône µ   qui possède avantageusement un gradin   plat 4.   La partie 5 en forme de tronc de cône est délimitée par un renfoncement ou par un bourrelet 5 refoulé vers l'extérieur qui se raccorde au bord proprement dit 6, relativement épais. 



   Dans une rainure annulaire de la partie 6 est placé 

 <Desc/Clms Page number 3> 

 un anneau en caoutchouc 7. La paroi périphérique 8 du cou- vercle possède un certain nombre de languettes ou de pattes 
9 qui sont recourbées quelque peu vers l'intérieur du cou- verole et s'engagent en-dessous du bord replié 10 de la boi- te à conserve. Le bord de la boîte à conserve est donc ser- ré solidement entre l'anneau de caoutchouc souple 7 et les différentes pattes 9, ce qui produit une fermeture herméti- que de la boîte. Pour obtenir une fixation sûre par les pattes 9, ces dernières possèdent des coins repliés vers l'intérieur 11 et 12. 



   Des essais approfondis faits avec des boîtes à conser- ve qui ont été fermées au moyen du nouveau couvercle ont prouvé que le contenu de la boite reste pratiquement stérile et que l'on peut cuire les boites sans inconvénient, sans que le couvercle saute ou que de l'air   pénètre.   



   Le nouveau couvercle peut êgalement être employé pour la fermeture de cruches à lait, de boîtes de tôle, de réci- pients à huile, etc.. Partout où on désire réaliser une fermeture simple et hermétique de boîtes ou de récipients, on se sert d'un couvercle suivant la présente invention qui doit être conformé d'après la forme du récipient.

  Lid for boxes and containers of all kinds, in particular for canning boots @
The present invention relates to a lid which is preferably intended to seal airtight cans in use.



   Until now, old cans that were to be used again were cut by machines and closed again by sealing machines. In this way of proceeding, the capacity of the cut tin can becomes smaller. Similar cutting and sealing machines are not available in the household, so open cans must be rejected.



   According to the present invention, the open cans are closed by a cover which is pressed without any accessory means, by hand, on the can and immediately closes the latter in an airtight manner. This hermetic closure is obtained by the fact that in an annular groove in the bottom of the cover is placed a ring

 <Desc / Clms Page number 2>

 about 3 to 6 mm rubber. thick and the cylindrical peripheral wall of the lid is provided with tabs or spring tabs which, when the lid is applied, fit below the thick edge of the tin can and hold the cover securely in position. The box filled beforehand can then be subjected to cooking without the lid popping up.



   To ensure secure engagement of the tabs in each case, the corners of the tabs may be curved inwardly of the cover. In addition, the bottom of the cover has a flat central part surrounded by a bead and which connects to a truncated cone part, as well as various annular recesses so that it can bulge upwards under the effect of pressure arising during cooking.



   The drawing shows by way of example an embodiment of the new cover.



   Fig. 1 is a top view of the cover.



   Fig. 2 is a vertical section through the cover.



   Fig. 3 is a perspective view on a larger scale of the tab.



   Fig. 4 shows a tin can closed with the new lid -
In the embodiment of the cover according to figs. 1 and 2, the bottom consists of a flat central part 1 which is delimited by a bead or a recess 2 forced towards the inside of the cover. The annular recess 2 is connected to a portion in the form of a truncated cone µ which advantageously has a flat step 4. The portion 5 in the form of a truncated cone is delimited by a recess or by a bead 5 forced outwards which is connects to the actual edge 6, relatively thick.



   In an annular groove of part 6 is placed

 <Desc / Clms Page number 3>

 a rubber ring 7. The peripheral wall 8 of the cover has a number of tabs or tabs
9 which are curved somewhat inward of the lid and engage below the folded edge 10 of the can. The edge of the can is therefore firmly clamped between the flexible rubber ring 7 and the various tabs 9, which produces a hermetic seal of the can. To obtain a secure fixing by the legs 9, the latter have corners bent inwards 11 and 12.



   Extensive tests with cans which have been closed with the new lid have shown that the contents of the can remain practically sterile and that the cans can be cooked without inconvenience, without the lid popping or air enters.



   The new cover can also be used for closing milk jugs, tin cans, oil containers, etc. Wherever it is desired to achieve a simple and airtight closing of cans or containers, use is made of a cover according to the present invention which is to be shaped according to the shape of the container.
