Abstract

La présente invention concerne un récipient de séparation stratifié pour substances de viscosité élevée, dont il est possible d'évacuer le contenu de manière appropriée, et avec lequel il est possible de supprimer de manière appropriée l'intrusion d'air extérieur dans le sac interne après évacuation, même si une substance de viscosité élevée est stockée à l'intérieur de celui-ci. Selon la présente invention, ce récipient de séparation stratifié comprend un corps de récipient destiné à loger des substances de viscosité élevée ayant une viscosité d'au moins 100 mPa·s à 20 °C, et un capuchon qui est adapté à une ouverture du corps de récipient, le corps de récipient comprenant une coque externe et un sac interne, le sac interne se séparant de la coque externe et se contractant en réponse à la réduction du contenu. Le bouchon comprend une partie cylindrique et une partie soupape positionnée à l'intérieur de la partie cylindrique, la partie soupape comprenant une partie base qui fait saillie à l'intérieur du corps de récipient, et une partie de raccordement qui relie la partie base et la partie cylindrique. La partie base est équipée d'une partie plate ayant disposé sur celle-ci un orifice d'évacuation en forme de fente d'intersection, et la partie de raccordement est équipée d'une partie incurvée qui fait saillie vers l'extérieur du corps de récipient. La partie base est constituée de telle manière que lorsqu'une pression est appliquée sur le corps de récipient, la partie plate est pressée par la substance de viscosité élevée de manière à être poussée vers l'extérieur du corps de récipient, et l'orifice d'évacuation est ouvert, et lorsque la pression sur le corps de récipient est retirée, la partie plate retourne à un état de saillie à l'intérieur du récipient, et l'orifice d'évacuation est fermé, ce qui permet d'empêcher l'intrusion de l'air extérieur à l'intérieur du sac interne.
