<p><P>PROBLEM TO BE SOLVED: To provide a paper packaging container that suppresses a liquid as its contents from flowing out of a straw inserted into the paper container formed by shaping a packaging strip into a tube and filling it with the liquid. <P>SOLUTION: The front face 12 and back face 14 of a paper container 1 each have three sets of embossed portions 17 of length W1. Both ends 17a of each embossed portion 17 is formed into an arcuate shape by round processing. When the dimension between the top face 10 and the bottom face 11 is a height H, the three sets of embossed portions 17 are located in positions vertically dividing the height H of the front 12 and back 14 by four so as to be parallel to the top face 10. The widths W of the front 12 and back 14 of the paper container 1 are greater than the widths S of a pair of sides 13 and 15. Each embossed portion 17 projects in the inward direction of the paper container 1 such that the width W1 is greater by 50% or more of the width W of the front 12. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
