<P>PROBLEM TO BE SOLVED: To provide a squeezing type extraction container which can be uniformly squeezed, and which can be smoothly extracted to the very last by the formation of a bonding strip having little effects in the appearance as a technical subject. <P>SOLUTION: This extraction container has an extraction cap body which is separably laminated, and assembled with and fixed to the mouth part of a delaminating bottle type container main body. The extraction container is constituted by providing a pair of vertical strip-form restricting strips formed of a pair of vertical thin strip-form bonding strips for which external and internal layers are bonded extending to an approximately total height range of the container main body to be approximately axially symmetrical to the central axis of an external container body. Then, on the discharging cap body, a first check valve part for preventing a reverse flow of a content into an internal container body from occurring and preventing the outside air from entering the internal container body is provided. Also, on the external container body, an air suction part for introducing the outside air to a space between the external and internal layers is formed. Then, a second check valve part is provided in a manner to open/close the air suction part so that the discharge of air from the air suction part is made impossible. <P>COPYRIGHT: (C)2004,JPO |
