Container and container with enclosed contents

A container includes a bag, which has an internal space to accommodate contents and an opening, and a fastener to open and close the opening. The fastener includes a high engaging-strength portion and a low engaging portion. The bag includes a bag body forming the internal space and a vapor passage portion to remove vapor from the internal space, and places contents into the internal space through the opening.

A steam release standing pouch has a structure in which the sealing portion is reliably peeled, and a content sealing standing pouch formed using the pouch. The steam release standing pouch has a first vapor passage portion. The distance between the inner edge of the tip of the vapor passage portion and the center of maximum expansion, which is the center of the portion where expansion is expected to be maximal, is shorter than either the distance between the inner edge of the first upper side portion and the center of maximum expansion or the distance between the inner edge of the first intermediate side portion and the center of maximum expansion.

Steam release standing pouch and content-enclosing standing pouch

A container having: a bag body including an internal space to accommodate a content; an opening formed in the bag body and communicating the internal space to an outside of the container; and a fastener to open and close the opening, wherein the fastener includes a high engaging-strength portion and a low engaging-strength portion, the engaging strength of the low engaging-strength portion is less than the engaging strength of the high engaging-strength portion, the fastener includes a female track and a male track, and the low engaging-strength portion is a part of the fastener in which at least one of the female track and the male track is collapsed.
