Abstract

The invention relates to a device comprising a piston lid 1 provided with a piston head 2 which slide by friction, while allowing the evacuation of air, in a cylindrical or parallelepipedic container in order to come into contact with the product contained in the container 3 and to thus maintain it shielded from air. The piston lid 1 has three notches 7 for the evacuation of air, a shoulder 8 positioning the piston head 2. The piston head is a thin flexible membrane in the shape of a slightly splayed bowl. This device according to the invention is particularly intended for the preservation of food or industrial products liable to deterioration in air, during consumption or use.

Description

La présente invention concerne un dispositif pour conserver les produits altérables à l'air. Bien qu'hermétiques les couvercles de boîtes de produits alimentaires ou chimiques altérables à l'air n'éliminent pas traditionnellement la présence d'air au contact du produit restant après un début d'utilisation. Ce qui gêne ou interdit parfois le réemploi de ces produits. The present invention relates to a device for storing weatherable products in air. Although airtight, the covers of boxes of food or chemical products which can be altered in air do not traditionally eliminate the presence of air in contact with the product remaining after a start of use. This sometimes hinders or prohibits the reuse of these products.

Le dispositif suivant notre invention permet de remédier à cet inconvénient. The device according to our invention overcomes this drawback.

Il comporte un couvercle piston (1) muni d'une tête de piston (2) qui coulissent par frottement en permettant l'évacuation de l'air dans un récipient cylindrique (3) ou parallèlépipédique afin de venir au contact du produit contenu dans le récipient et de le maintenir ainsi à l'abri de l'air. Le bord supérieur du récipient légèrement évasé (4) pour faciliter l'introduction du couvercle peut comporter un bec verseur (5). Le couvercle piston possède une poignée (6) pour sa manoeuvre et trois encoches (7) à sa périphérie permettant l'évacuation de l'air. Sa forme est telle qu'il coulisse par frottement à l'intérieur du récipient. Il possède un épaulement (8) permettant le positionnement de la tête de piston.La tête de piston constituée d'une fine membrane souple est mise en place au contact du produit par le couvercle piston et peut descendre jusqu'au fond du récipient suivant son remplissage. Sa forme en cuvette légèrement évasée permet l'échappement de l'air par effacement de ses bords face à la pression d'air lors de son enfoncement dans le récipient. Son diamètre extérieur est légèrement supérieur au diamètre intérieur du récipient. It comprises a piston cover (1) provided with a piston head (2) which slide by friction allowing the evacuation of air in a cylindrical container (3) or parallelepiped in order to come into contact with the product contained in the container and keep it well away from air. The upper edge of the slightly flared container (4) to facilitate the introduction of the cover may include a pouring spout (5). The piston cover has a handle (6) for its operation and three notches (7) at its periphery allowing the evacuation of air. Its shape is such that it slides by friction inside the container. It has a shoulder (8) allowing the positioning of the piston head. The piston head consisting of a thin flexible membrane is placed in contact with the product by the piston cover and can descend to the bottom of the container according to its filling. Its slightly flared bowl shape allows the air to escape by erasing its edges when faced with air pressure when it is pushed into the container. Its outside diameter is slightly greater than the inside diameter of the container.

L'ensemble du dispositif peut être réalisé de préférence en matière plastique. The entire device can preferably be made of plastic.

La tête de piston sera utilisee lors de conservation de longue durée ou dans le cas de produit durcissant à l'air. Elle est destinée à être détruite avant la réutilisation du produit. Dans d'autres cas de conservation seul le piston peut être utilisé pour assurer l'étanchéité à l'air souhaitée. The piston head will be used for long-term storage or in the case of air-hardening product. It is intended to be destroyed before the product is reused. In other conservation cases only the piston can be used to ensure the desired airtightness.

Le dispositif selon notre invention est particulièrement destiné à la conservation de produits alimentaires ou industriels altérables à l'air, en cours de consommation ou d'utilisation.  The device according to our invention is particularly intended for the conservation of food or industrial products alterable to the air, during consumption or use.
