Abstract

L'invention porte sur un sac à vide pour conserver une fraîcheur avec une soupape d'extraction d'air (20) et un dispositif de fixation d'étanchéité (40), lequel sac comprend un film de sac en caoutchouc (10), une soupape d'extraction d'air (20) et un dispositif de fixation d'étanchéité (40). La soupape d'extraction d'air (20) est constituée par une feuille de soupape (21), un siège de soupape (22) et un revêtement de soupape (23), et est disposée entre des films supérieur et inférieur du sac en caoutchouc. Une face du siège de soupape (22) adhère fermement à la surface interne d'un film de sac en caoutchouc, et, sur la surface de l'autre face, se trouvent une pluralité de rainures (221), et le revêtement de soupape (23) encercle le siège de soupape selon une adaptation étroite. Au centre de la feuille de soupape (21), située entre le siège de soupape (22) et le film de sac en caoutchouc (10), fait saillie une tête effilée (211), la tête effilée (211) étant en adaptation étroite avec un trou effilé sur le siège de soupape (22). Le sac à vide pour conserver une fraîcheur peut être recyclé ou réutilisé de nombreuses fois, de façon à éviter ainsi les déchets. La rainure sur la face du siège de soupape forme un chemin d'air étroit avec le revêtement de soupape à adaptation étroite, permettant à de l'air dans le sac d'être filtré et empêchant ainsi de la crasse d'entrer sur la surface hermétiquement scellée de la feuille de soupape et du siège de soupape. La structure de la tête effilée de la feuille de soupape garantit encore davantage la fiabilité du joint d'étanchéité. Le sac à vide pour conserver une fraîcheur est apte à l'utilisation à la maison, dans des bars, dans des cantines et lors du voyage à l'extérieur, etc., et la coopération avec un appareil d'extraction d'air peut permettre un stockage sous emballage comprimé et sous vide d'aliments et d'articles précieux, etc.
