A resin composition for injection forming containing a high-density polyethylene, an ethylene-vinyl alcohol copolymer and an acid-modified linear low-density polyethylene, characterized in that the ethylene-vinyl alcohol copolymer is contained in an amount of 35 to 90 parts by mass and the acid-modified linear low-density polyethylene is contained in an amount of 10 to 35 parts by mass per 100 parts by mass of the high-density polyethylene.

Resin composition for injection forming

A container lid () can be removed from a mouth-neck section () of a container without the need for a tool. Following the breakage of a breakable thin-walled line () in a transition region (), the breakage of a breakable thin-walled connection wall () in a side wall separation region () can be started sufficiently smoothly in the container lid (). For this purpose, the breakable thin-walled line () formed in a side wall () in the transition region () is brought into a form in which at least a part thereof extends obliquely downwardly in a counterclockwise direction.
