<p><P>PROBLEM TO BE SOLVED: To provide a flexible container capable of easily discharging contents remaining at a neck section and in the vicinity of the neck section by facilitating collapse and deformation of the neck section formed by fusion bonding a film member. <P>SOLUTION: In the synthetic resin-made flexible container 10 wherein the content stored in a flexibly deformable container body 11 is pushed out from an opening 13 at the tip of a neck section 12 where a male screw 15 is arranged on an outer peripheral surface, a synthetic resin-made film member 30 covering the opening 13 at the tip of the neck section 12 and forming a discharge hole 31 in the middle part is fusion bonded. A plurality of opening-out lines 32 extending to a peripheral edge of the opening 13 at the tip of the peripheral edge of the discharge hole 31 and tearing with collapse and deformation of the opening 13 at the tip are formed on the film member 30 in the peripheral direction at regular intervals. The discharge hole 31 has a star-shape, and the opening-out line 32 is extended to a peripheral edge 13a from the tip of each outside corner section 31b of the star-shape. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
