Title:
RESIN CAP
Document Type and Number:
WIPO Patent Application WO/2012/020637
Kind Code:
A1
Abstract:
Provided is a resin cap which is easy to produce and makes it possible to prevent adhesion of ink on the back surface of a top plate during the printing process without causing an increase in weight. A one-piece resin cap (1) comprises: a top plate (2); a side wall part (3) which extends axially in one direction from an outer peripheral edge (2a) of the top plate (2); and an inner ring (6) which extends as a single unit from a back surface (2b) of the top plate (2) toward the inside, and adheres to the inside surface of a container opening. The width of the interval between a printing blanket (51) and a mandrel (50) is increased without changing the thickness of the top plate (2), by forming, on the back surface (2b) of the top plate (2), a rib (13) for preventing the mandrel (50) from directly touching the back surface (2b) when printing is performed on the front surface (2d) of the top plate (2).
