Title:
LAMINATED SEPARATING CONTAINER FOR HIGH-VISCOSITY SUBSTANCES
Document Type and Number:
WIPO Patent Application WO/2016/125784
Kind Code:
A1
Abstract:
Provided is a laminated separating container for high-viscosity substances, with which it is possible to discharge the content thereof appropriately, and with which it is possible to appropriately suppress the intrusion of outside air into the inner bag after discharge, even if a high-viscosity substance is stored therein. According to the present invention, this laminated separating container comprises a container body for housing high-viscosity substances having a viscosity of at least 100mPa·s at 20°C, and a cap which is fitted to an opening of the container body, the container body comprising an outer shell and an inner bag, the inner bag separating from the outer shell and contracting in response to the reduction in content. The cap comprises a cylindrical portion and a valve part positioned inside the cylindrical portion, the valve part comprising a base portion which protrudes into the inside of the container body, and a connecting part that connects the base portion and the cylindrical part. The base portion is equipped with a flat part having provided thereto an intersecting slit-shaped discharge port, and the connecting part is equipped with a curved part which protrudes towards the outside of the container body. The base part is constituted in such a manner that when pressure is applied to the container body, the flat part is pressed by the high-viscosity substance so as to be pushed out towards the outside of the container body, and the discharge port is opened, and when the pressure on the container body is removed, the flat part returns to a state of protruding into the interior of the container, and the discharge port is closed, thereby preventing the intrusion of outside air into the interior of the inner bag.
