<p><P>PROBLEM TO BE SOLVED: To provide a flexible container which allows its contents left over in the vicinity of its neck part to be efficiently and easily extruded from a container body with its cross sectional area so formed as if it is squeezed as it extends toward the neck part. <P>SOLUTION: The flexible container 10 is made of synthetic resin, capable of extruding and delivering, from the outlet port 13 at the tip of the neck part 12, the contents encased in the container body 11 which is equipped with a pair of pressing surfaces 20a, 20b respectively on the front surface side and rear face side, which are given pressing forces toward mutually approaching directions, while having a cross sectional area of squeezed shape toward the neck part 12, and which is provided with depressed guiding lines 19 extending from the vicinity of the neck part 12 to downward, respectively at the central portions of the pair of pressing surfaces 20a, 20b. The external thread 15 formed on the outer peripheral surface of the neck part 12 is provided with intermittent lacks 16, each of which lacks a protrusive bar constituting the thread 15, for arrangement along the extensions of the depressed guiding lines 19, parallel to the axial direction X of the neck part 12, while concave channels 17 are formed, traversing longitudinally through these intermittent lacks 16. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
