Abstract

The invention makes it possible to keep air away from liquid products. It consists of a rigid sealed container 1, a closure member 2 for the filling or using of the product, possibly a drawing-off orifice 3, an expandable chamber 4 with its orifice 5 making it possible to inflate the chamber 4 in order to remove the air in contact with the liquid or to bring the chamber 4 to atmosphere in order to expand it by the reduced pressure of the liquid when the vent 6 is closed off. The device according to the invention is intended for the storage of liquid products.

Description

la présente invention concerne un dispositif permet- tant d'évacuer, d'un récipient rigide et étanche, le volume d'air en contact avec un produit liquide à stocker. the present invention relates to a device making it possible to evacuate, from a rigid and sealed container, the volume of air in contact with a liquid product to be stored.

le dispositif suivant l'invention a pour fonction de permettre d'évacuer le maximum d'air en contact avec le produit liquide à stocker dans un récipient rigide et étanche muni d'un obturateur servant au remplissage ou à l'utilisation du produit "et" ou à permettre un soutirage du produit liouide sans avoir de contact avec l'air pénétrant par dépression dans le récipient lors d'un soutirage. the device according to the invention has the function of making it possible to evacuate the maximum amount of air in contact with the liquid product to be stored in a rigid and sealed container fitted with a shutter used for filling or using the product "and "or to allow a withdrawal of the liquid product without having contact with the air penetrating by vacuum into the container during a withdrawal.

Dans les récipients de stockage classiques le volume d'air emmagasiné augmente avec l'utilisation des produits et provooue une réaction chimioue,due à l'oxygène,ou la volatisation d'éléments nécessaires à une bonne utilisation de ces produits liouides stockés. in limitant le volume d'air en contact avec le produit celui-ci aura une durée de conservation jusqu'à l'épuisement du stock ou jusque la date limite de conservation. In conventional storage containers the volume of stored air increases with the use of the products and provokes a chemical reaction, due to oxygen, or the volatilization of elements necessary for a good use of these stored liquid products. by limiting the volume of air in contact with the product, it will have a shelf life until the stock is exhausted or until the expiry date.

Suivant la figure I schématisée en coupe,il se compose d'un récipient rigide et étanche (1) muni d'un obturateur (2) permettant le rentlissage ou l'utilisation du produit liquide, ce sera un couvercle ou un bouchon suivant le récipient et l'utilisation,d'un orifice d'écoulement (3) si l'utilisation du produit liquide nécessite un soutiraEe,d'une chambre expan- sible (4) formée par une membrane, une vessie ou un soufflet, occupant en expansion le volume du récipient (i) et constituée d'une matière compatible avec le produit contenu dans le récipient (4),d'un orifice (5) pour le gonflage ou la mise à l'atmosphère de la chambre expansible (4),d'un évent (6) permettant l'évacuation de l'air en contact avec le produit licuide emmagasiné après la fermeture du récipient (1). Cet évent (6) possède un système d'obturateur pouvant rendre étanche le récipient (i) après l'évacuation de l'air. According to Figure I schematically in section, it consists of a rigid and sealed container (1) provided with a shutter (2) allowing the lamination or the use of the liquid product, it will be a cover or a cap according to the container and the use, of a flow orifice (3) if the use of the liquid product requires a filling, of an expandable chamber (4) formed by a membrane, a bladder or a bellows, occupying in expansion the volume of the container (i) and consisting of a material compatible with the product contained in the container (4), of an orifice (5) for the inflation or venting of the expandable chamber (4), a vent (6) allowing the evacuation of the air in contact with the liquid product stored after the closure of the container (1). This vent (6) has a shutter system which can seal the container (i) after the air has been removed.

La figure 2 schématisée en coupe,représente le récipient (1),après l'utilisation d'une ouantité quelconque du produit liquide ou après un remplissage incomplet, fermé par son obturateur (2). le système d'étanchéité de l'évent (6) étant libéré. Figure 2 schematically in section, shows the container (1), after using any quantity of the liquid product or after an incomplete filling, closed by its shutter (2). the vent sealing system (6) being released.

la figure 3 schématisée en coupe,représente la chambre expansible (4) en partie gonflée par l'orifice (5). le volue du produit manquant est compensé par la chambre expansible (4). Figure 3 schematically in section, shows the expandable chamber (4) partially inflated by the orifice (5). the volume of the missing product is compensated by the expandable chamber (4).

le produit liquide restant monte dans le récipient (1),évacue l'air contenu dans le haut du récipient (1) par l'évent (6).the remaining liquid product rises in the container (1), evacuates the air contained in the top of the container (1) through the vent (6).

La figure 4, schématisée en coupe, représente la chambre expansible (4) avec son orifice (5) libéré pour la mise à l'atmosphère de la chambre expansible (4) après aue l'évent (6) ait été rendu étanche. Sous l'effet de la dépression,provoqueé par le liquide, sur la paroi extérieure de la chambre expansible (4) et de la pression atmosphèrique agissant à l'intérieur de la chambre expansible (4) celle-ci reste en contact avec le produit liquide. Dans le cas d'un soutirage par l'orifice d'écou lement (3) l'expansion de la chambre (4) sera automatique en fonction du volume soutiré. Figure 4, shown schematically in section, shows the expandable chamber (4) with its orifice (5) released for the venting of the expandable chamber (4) after aue the vent (6) has been sealed. Under the effect of the depression, caused by the liquid, on the outer wall of the expandable chamber (4) and of the atmospheric pressure acting inside the expandable chamber (4) the latter remains in contact with the product. liquid. In the case of withdrawal by the flow orifice (3), the expansion of the chamber (4) will be automatic as a function of the volume withdrawn.

Le produit restera à l'abri de l'air donc de l'oxygène et pourra ainsi être stocké. The product will remain sheltered from air and therefore from oxygen and can thus be stored.

l'expansion du liquide,due aux différences de tempêra- ture ambiante,sera compensée par la chambre expansible (4) mise à l'atmosphère. the expansion of the liquid, due to the differences in ambient temperature, will be compensated by the expandable chamber (4) vented.

Des variantes peuvent être apportées:
A l'emplacement de l'orifice (5) de mise à l'atmosphère de la chambre expansible (4). Son usage sera identique s'il est fixé sur l'obturateur (2) ou sur le récipient (1).Variants can be made:
At the location of the orifice (5) for venting the expandable chamber (4). Its use will be identical if it is fixed on the shutter (2) or on the container (1).

k l'orifice d'évent (6) cui peut être à la fois orifice de remplissage dans certains types de récipients. k the vent orifice (6) which can be both a filling orifice in certain types of receptacles.

le dispositif selon l'invention est destin au stockage des produits liquides et cencerne l'industrie de l'emballage et du conditionnement.  the device according to the invention is intended for the storage of liquid products and surrounds the packaging industry.
