Abstract

L'invention concerne un dispositif pour distribuer un produit qui se trouve sous pression, comprenant un sachet souple qui présente une ouverture de sortie, des moyens élastiques qui exercent sur le sachet une pression en direction de son centre étant disposés autour du sachet. Selon l'invention, pour créer un dispositif approprié pour distribuer un produit se trouvant sous pression, qui permet d'obtenir un vidage au moins sensiblement complet du dispositif avec un débit de sortie régulier, les moyens élastiques sont constitués par au moins un ruban élastique qui est disposé autour du sachet au moins dans certaines régions. Dans le cadre de l'invention, il a été constaté de façon surprenante qu'au moyen d'un ruban élastique qui est enroulé autour du sachet souple, il est possible d'obtenir une sollicitation en pression du sachet qui correspond sensiblement à la sollicitation en pression telle qu'elle se produit dans un récipient sous pression. Il est possible d'obtenir non seulement un débit de sortie régulier, de la première à la dernière application, mais encore un vidage pratiquement total du contenu du sachet.
