Abstract: A steam-releasing pouch includes two laminated sheets forming an accommodation compartment that accommodates a content, a sealing portion that seals the two sheets to form an opening that opens part of the accommodation compartment, and a steam-releasing sealing portion formed in the sealing portion to open as pressure of the accommodation compartment increases in a state in which the opening is sealed. The steam-releasing sealing portion includes a first sealant layer having at least a first base layer that faces the accommodation compartment and a second base layer laminated with the first base layer and a second sealant layer having at least a third base layer that faces the accommodation compartment and a fourth base layer laminated with the third base layer. The first base layer and the third base layer are joined together.

Abstract: The steam-releasing flat pouch comprises a seal part, a steam-releasing seal part, and a steam discharge part. The seal part seals stacked sheets. The steam-releasing seal part is located in the inner parts of the sheet inside the seal part, and is configured to join parts of the sheet so that they are not continuous with the seal part. The steam discharge part is formed in the steam-releasing seal part and configured not to allow communication with the outside when the steam-releasing seal part is not peeled, and to allow communication with the outside when the steam-releasing seal part is peeled. The steam-releasing seal part includes an anterior peeling part including a part that peels apart first as the pressure increases, and a posterior peeling part including a part that peels apart last. The width of the posterior peeling part is smaller than the width of the anterior peeling part.

Abstract: A pouch includes two sheets placed one upon another, a seal, and a non-sealed portion. The seal includes a first seal portion and a second seal portion. The first seal portion extends along an edge of the two sheets. The second seal portion is depressed toward the accommodation cavity. The second seal portion includes a distal end portion and a connection portion. The distal end portion is configured to be ripped by stress concentration that occurs when steam generated from the contents raises pressure of the accommodation cavity. The connection portion is configured to connect the distal end portion and the first seal portion. The connection portion includes a ripping restriction portion configured to restrict ripping of the second seal portion that progresses from the distal end portion toward the first seal portion.

Abstract: Provided is an instant noodles container lid that provides indication according to elapse of time from the start of boiling water process. An instant noodles container lid includes a surface member, an intermediate member, and a seal base member having a sealant layer in order, respectively, from one surface side. The surface member has a printed layer in an area other than a first area. The intermediate member includes a paper layer, a printed layer, a filling layer, and a wax layer in order, respectively, from the one surface side, and the wax layer is in a second area that covers the first area. A first half cut is formed from the surface member into the paper layer, in the first area. A second half cut is formed in the second area from the filling layer into the paper layer in a portion outside of the first area.
