A pouch according to an embodiment is a pouch having an accommodation space that accommodates contents, and including a pair of sheets, and a pair of side seal portions sealed to form the accommodation space, wherein at least one of the pair of side seal portions includes a first seal portion located near the top portion, a second seal portion located near the bottom portion and separated from the first seal portion, and a steam discharge seal portion configured to connect the first and second seal portions, to protrude to the accommodation space side, and to release steam, a portion formed by a first region between the first and second seal portions and a second region surrounded by the first region and the steam discharge seal portion is an unsealed region, and a penetration portion that passes through at least one sheet in a thickness direction is formed in the unsealed region of the at least one sheet.

Pouch

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.

Steam-releasing pouch

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.

Instant noodles container lid

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.
