Abstract

The contents of a paint can are preserved by means of an inflatable internal rubber or plastic membrane having an inflation valve. The membrane is stuck on the bottom. There is a transparent indicator and a vent in the lid so that the user can purge the air from the can.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

Description de l'invention : De tout temps l'usage de contenants fut nécessaire. Description of the invention: The use of containers has always been necessary.

Aujourd'hui plus qu'hier de la bouteille au pot de peinture les contenants étanches ou semi-étanches sont d'usage courant. Today, more than yesterday, from the bottle to the paint can, sealed or semi-sealed containers are in common use.

Cette invention les concerne en particulier. This invention relates to them in particular.

Je la décris ci-dessous pour un pot de peinture. I describe it below for a can of paint.

Objectif de l'invention : Améliorer la conservation du contenu en chassant l'air indésirable dans un pot de liquide entamé avant sa fermeture. Objective of the invention: To improve the preservation of the contents by expelling the undesirable air in a jar of liquid started before it is closed.

Moyens : Par mise en place d'un ballon de type caoutchouc ou d'un sac en plastique fin et résistant collé ou fixé par des clips à l'intérieur et au fond du pot. Ce pot est traversé par une soupape permettant le gonflage du ballon ou du sac au moyen d'une pompe. Means: By placing a rubber balloon or a thin and resistant plastic bag glued or fixed by clips inside and at the bottom of the pot. This pot is crossed by a valve allowing the inflation of the balloon or the bag by means of a pump.

Une pompe à vélo ou de type poire peut suffire. A bicycle or pear-type pump may suffice.

Mode d'emploi : Apres avoir consommé la moitié de son pot de peinture l'utilisateur souhaite le conserver longtemps. Instructions for use: After having consumed half of its paint can the user wishes to keep it for a long time.

1/L'utilisateur adapte la pompe sur la valve et gonfle doucement le ballon collé sur une face au fond du pot ce qui provoque une élévation du niveau de la peinture restante.  1 / The user adapts the pump to the valve and gently inflates the balloon stuck on one side to the bottom of the pot, which causes the level of the remaining paint to rise.

2/Lorsque le niveau atteint le bord du pot l'utilisateur referme le couvercle du pot et l'opération est terminée.  2 / When the level reaches the edge of the pot the user closes the lid of the pot and the operation is finished.

La peinture en l'absence de contact avec l'air ne formera pas de croûte.  Paint in the absence of contact with air will not form a crust.

Remarques qualitatives : La membrane du ballon ou du sac doit rester imperméable à l'air, ne pas être percée ni dissoute par le liquide. Qualitative remarks: The membrane of the balloon or bag must remain impermeable to air, not be pierced or dissolved by the liquid.

La pression à l'extérieur et à l'intérieur du pot s'équilibrera toute seule par les fuites de la valve qui a pour seule mission de permettre au ballon ou au sac de rester gonfler le temps nécessaire à la fermeture du pot. The pressure outside and inside the jar will balance itself by leaking the valve which has the sole mission of allowing the balloon or bag to remain inflated for the time necessary to close the jar.

Le liquide à l'intérieur du pot ne devra pas fuir par la valve solidement fixée sur le pot The liquid inside the jar should not leak through the valve securely attached to the jar

<Desc/Clms Page number 2> <Desc / Clms Page number 2>

Le système utilise de l'air mais pourrait dans certains cas utiliser de l'eau ou tout autre matière liquide ou gazeuse pour gonfler un sac ou un ballon. The system uses air but could in some cases use water or any other liquid or gaseous material to inflate a bag or balloon.

Améliorations possibles : Une amélioration du couvercle du pot est possible par adjonction d'un purgeur pour évacuer l'air et d'un indicateur de niveau pour permettre de réaliser la même opération que décrite ci-dessus mais à couvercle fermé ce qui présente l'avantage de ne pas risquer de renverser le pot pendant l'opération du gonflage du ballon et de chasser le maximum d'air de l'intérieur. Possible improvements: An improvement of the lid of the pot is possible by adding a steam trap to evacuate the air and a level indicator to allow to carry out the same operation as described above but with closed lid what presents the advantage of not risking overturning the pot during the inflation process of the balloon and expelling the maximum amount of air from the inside.

La purgeur devra alors être refermé L'indicateur de niveau peut être un insert transparent dans le couvercle. The steam trap must then be closed. The level indicator can be a transparent insert in the cover.

Un usage industriel du système peut permettre d'employer toujours la même taille de pot indépendamment de la quantité de liquide à l'intérieur. Industrial use of the system can make it possible to always use the same pot size regardless of the amount of liquid inside.

Le coût réduit de la mise en place d'un tel système peut permettre de l'installer sur des pots de quelques euros sans grever lourdement leurs prix de vente.The reduced cost of setting up such a system can allow it to be installed on pots of a few euros without severely burdening their selling prices.
