<p><P>PROBLEM TO BE SOLVED: To provide a plastic container with buckling resistance which achieves much greater weight reduction and thin wall formation required for a container to be used for aseptic filling, and suppresses generation of a mark of buckling deformation causing decrease in appearance by bending the container when a load is applied. <P>SOLUTION: This plastic container with buckling resistance has a mouth part, a shoulder part, a label part, a barrel part and a bottom part orderly from the top. In the plastic container with a square shape in which a plurality of annular channel-like recessed stripe parts continuous on the whole periphery are provided horizontally and in parallel each other on respective side faces of the label part and the barrel part, and the side faces have wall face parts and corner parts, either one of the recessed stripe parts of the barrel part or the label part has such a structure that the depths of the channels of the uppermost stage and the lowermost stage are made deeper than other recessed stripe parts pinched by the recessed stripe parts, and the other recessed stripe parts of the barrel part or the label part have two step channel structures in which a channel is furthermore provided on the channel bottom of the recessed stripe passing on the wall face part. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
