Cap and capped container

Abstract

To provide a cap and a capped container that prevent a user from feeling a sense of discomfort about a torque when the cap is opened while reliably preventing the inversion of a flap when the cap is opened. Provided is a cap ( 10 ) having a TE band ( 30 ), with this TE band ( 30 ) having a flap ( 32 ), the flap ( 32 ) has a flange engaging part ( 32 b ) and an attitude maintaining piece ( 32 c ), and an inner peripheral wall of the band body part ( 31 ) has a release part ( 22 c ) that forms a gap between an outer peripheral wall of the attitude maintaining piece ( 32 c ) and the inner peripheral wall of the band body part ( 31 ) when the cap is attached to the container. A circumferential width of the attitude maintaining piece ( 32 c ) is formed to be narrower than a circumferential width of a flap body ( 32 a ).

1 . A cap having a cap body and a TE band connected to a lower end of the cap body via a weakening part, wherein
 the TE band has an annular band body part connected to the lower end of the cap body and a flap provided consecutively to a lower end of the band body part and folded back toward an inner peripheral side of the band body part,   the flap has a flap body provided consecutively to the lower end of the band body part, a flange engaging part formed on an inner peripheral side of the flap body and capable of engaging with a lower side of a container flange when the cap is attached to a container, and an attitude maintaining piece formed on an upper end side of the flap body and arranged on an outer peripheral side of the container flange when the cap is attached to the container,   an inner peripheral wall of the band body part has a release part that forms a gap between an outer peripheral wall of the attitude maintaining piece and the inner peripheral wall of the band body part when the cap is attached to the container, and a circumferential width of the attitude maintaining piece is formed to be narrower than a circumferential width of the flap body.   
     
     
         2 . The cap according to  claim 1 , wherein
 the flange engaging part and the attitude maintaining piece are formed so as not to overlap each other in the cap circumferential direction.   
     
     
         3 . The cap according to  claim 2 , wherein
 the attitude maintaining piece is formed at each of both ends in a circumferential direction of the flap body.   
     
     
         4 . The cap according to  claim 1 , wherein
 a thickness of the attitude maintaining piece is formed to be thinner than a thickness of the flap body at the thinnest spot thereof.   
     
     
         5 . A capped container having the cap according to  claim 1  and a container, wherein
 the container has a container mouth cylindrical part, a container-side thread part formed on an outer periphery of the container mouth cylindrical part, and the container flange formed on the outer periphery of the container mouth cylindrical part below the container-side thread part, and 
 a gap is formed between the outer peripheral wall of the attitude maintaining piece and the inner peripheral wall of the band body part when the cap is attached to the container.
