Abstract

A can container includes a can lid including a disk-shaped panel portion in which a circular score line defining a region for forming a drinking opening is formed on an outer peripheral edge side, a groove portion connected to the outer peripheral edge of the panel portion and recessed from the panel portion; and a can body including a cylindrical body portion, a fixing portion fixed to the flange portion, and a tapered portion provided between the body portion and the fixing portion and having a diameter reduced from the body portion toward the fixing portion, wherein a ratio between a diameter of the score line and an inner diameter of the body portion is 0.6 to 0.8.

What is claimed is: 
     
         1 . A can container comprising:
 a can lid including a disk-shaped panel portion in which a circular score line defining a region for forming a drinking opening is formed on an outer peripheral edge side, a groove portion connected to the outer peripheral edge of the panel portion and recessed from the panel portion, a rivet portion provided in the panel portion and adjacent to an inner side of the score line in a radial direction, a tab for an opening operation that is fixed to the rivet portion, and a flange portion connected to the groove portion, wherein the panel portion includes a panel outer peripheral portion in which a portion between the score line and the groove portion is inclined outward in an axial direction toward the inner side in the radial direction; and   a can body including a cylindrical body portion, a fixing portion fixed to the flange portion, and a tapered portion provided between the body portion and the fixing portion and having a diameter reduced from the body portion toward the fixing portion, the can body being filled with an effervescing content and having a positive internal pressure,   wherein   a ratio between a diameter of the score line and an inner diameter of the body portion is 0.6 to 0.8.   
     
     
         2 . The can container according to  claim 1 , wherein, in the tapered portion, a ratio between an inner diameter of an end portion on the fixing portion side and an inner diameter of an end portion on the body portion side is set to 0.75 to 0.9. 
     
     
         3 . The can container according to  claim 1 , wherein the can lid includes a convex portion provided on the score line side and the can body side of the panel outer peripheral portion. 
     
     
         4 . The can container according to  claim 2 , wherein the can lid includes a convex portion provided on the score line side and the can body side of the panel outer peripheral portion.
