Abstract: Provided is a container provided with a zipper tape including: a container body including at least a first area and a second area that are opposed to each other; a zipper tape including a first base strip being at least partially bonded to the first area, a second base strip being at least partially bonded to the second area, a first engagement portion and a second engagement portion respectively protruding from the first base strip and the second base strip and being engageable with each other; and a hinge is provided at at least one position that satisfies m/n<0.25, where “n” represents a length of an opening portion of the container body, and “m” represents a distance from the hinge to an inner end portion of the opening portion in a longitudinal direction of the zipper tape.

Abstract: A thin portion is provided near an opening of a bag body to a main body of a belt-like base connected to an engagement portion. The thin portion is provided between a thick first projecting portion and a thick second projecting portion. The thin portion is thinner than the first projecting portion and the second projecting portion. On the thin portion, ribs are provided in plural lines.

Abstract: A seal base, which is thicker than a thick portion and is bondable to an inner surface of a bag body, is continuously connected to one of belt-like bases of a zipper tape via a belt-like cutting portion that is thinner than the thick portion and separates a containing space from an outside. A first linking portion having a first corner (a) is defined by a cutting outer surface of the cutting portion and a seal outer continuous surface of the seal base. A second linking portion having a second corner (b) is defined by a contained cutting surface of the cutting portion and a contained seal continuous surface of the seal base.

Abstract: A thick portion is formed thick at an end of a female belt-like base near a containing space. To the thick portion near the containing space, a cut portion thinner than the female belt-like base is provided. To the cut portion near the containing space, a seal base that is thicker than the female belt-like base and is sealed to an inner surface of a bag body to which a male belt-like base is attached, is provided. Seal strength of the thick portion to the inner surface is lower than that of the seal base. The cut portion is provided to have a lower seal strength than that of the seal base. An area surrounded by the thick portion, the cut portion, the seal base and the inner surface becomes hermetically sealed. Even when external pressure is applied on the bag body, damages to the cut portion can be prevented.
