Resin made container

Abstract

A resin made container includes a spout portion acting as an outlet for contents, a shoulder portion continuous with the spout portion, a body portion continuous with the shoulder portion, and a bottom portion continuous with the body portion and closing a lower end of the body portion. The body portion includes a plurality of approximately quadrangular shaped panel portions each having an upper side and a lower side thereof displaced; and between adjacent panel portions, a chevron-shaped rib is provided. Also, there is provided an annular receded rib which is receded to the inner side of the resin made container and which extends in a circumferential direction of the resin made container. The receded rib includes a plurality of protruding ribs protruding in a direction intersecting the extending direction of the receded rib, the protruding ribs being receded from the surface of the resin made container.

1 . A resin made container comprising:
 a spout portion acting as an outlet for contents;   a shoulder portion continuous with the spout portion;   a body portion continuous with the shoulder portion; and   a bottom portion continuous with the body portion and closing a lower end of the body portion;   wherein the body portion includes a plurality of approximately quadrangular shaped panel portions each having an upper side and a lower side thereof displaced; and   between adjacent panel portions, a chevron-shaped rib is provided.   
     
     
         2 . The resin made container of  claim 1 , wherein the respective panel portion has a parallelogram shape and widths of the respective panel portions are made equal. 
     
     
         3 . The resin made container of  claim 1 , wherein the chevron-shaped rib has an angle ranging from 90 to 160 degrees. 
     
     
         4 . The resin made container of  claim 1 , wherein the chevron-shaped rib has a sloped face which extends with a uniform width from the upper side to the lower side of the resin made container. 
     
     
         5 . The resin made container of  claim 1 , wherein the panel portion includes, in at least one of its upper and lower parts, an annular receded rib which is receded to the inner side of the resin made container and which extends in a circumferential direction of the resin made container. 
     
     
         6 . A resin made container including: a spout portion acting as an outlet for contents; a shoulder portion continuous with the spout portion; a body portion continuous with the shoulder portion; and a bottom portion continuous with the body portion and closing a lower end of the body portion;
 wherein the resin made container comprises an annular receded rib which is receded to the inner side of the resin made container and which extends in a circumferential direction of the resin made container; and   the receded rib includes a plurality of protruding ribs protruding in a direction intersecting the extending direction of the receded rib, the protruding ribs being receded from the surface of the resin made container.   
     
     
         7 . The resin made container of  claim 6 , wherein the container includes from eight to twelve of the protruding ribs. 
     
     
         8 . The resin made container of  claim 6 , wherein the occupancy of the protruding ribs in the receded rib ranges from 30 to 60%. 
     
     
         9 . The resin made container of  claim 6 , wherein the bottom of the receded rib has a width of less than or equal to 15 mm. 
     
     
         10 . The resin made container of  claim 6 , wherein the amount of recession of the protruding ribs from the surface of the resin made container ranges from 0.3 to 3 mm. 
     
     
         11 . The resin made container of  claim 6 , wherein the receded rib and the protruding ribs are provided in either upper half of the resin made container. 
     
     
         12 . The resin made container of  claim 6 , wherein at the connecting portion between the body portion and the bottom portion, there are provided two annular bottom face side receded ribs that are receded to the inner side of the resin made container and that extend in the circumferential direction of the resin made container.
