<p><P>PROBLEM TO BE SOLVED: To provide a straw hole layout structure for a paper container which is unnecessary to paste a patch film for shading in a straw hole with no shading layer and has a shading characteristic. <P>SOLUTION: The straw hole 29 formed on a pillow-shaped packaging material 27 has a diameter S of 6 mm, and is arranged at the position S1 of 0.5 mm in the vicinity of an upper side seal 26a. The height H of the upper side seal 26a is approximately 7 mm. A pair of upper flaps 31 are formed by folding the upper side seal 26a along a top surface 30c, and a pair of lower flaps 32 are also formed by folding a lower side seal 26b along a bottom surface 30b. The paper container 30 is formed in a brick-shaped rectangular parallelepiped so that the upper flaps 31 and lower flaps 32 are firmly fixed on a side face 30a and the bottom surface 30b of the paper container 30 with thermal force-sticking, respectively, and the straw hole 29 is covered by the upper side seal 26a. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
