HEAT TREATMENT PACKAGE

PROBLEM TO BE SOLVED: To provide a heat treatment package to which contents such as food materials are put by a consumer for heat treatment and which hardly generates a rupture sound at the time of steam passage with increase in internal pressure.SOLUTION: A heat treatment package is a package for treating contents with heating comprises: a chuck seal part which tightly seals the package after inputting of contents to the inside; and a facing-type seal part which releases pressure when internal pressure increases due to heat treatment of the contents. An H-shaped seal region having non-seal parts on both package inner side and package outer side of the facing-type seal part is formed on the center of the facing-type seal part. Inverse U-shaped seal regions having a non-seal part on the package inner side of the facing-type seal part are formed on both sides of the H-shaped seal region.SELECTED DRAWING: Figure 1 【課題】消費者が食材等の内容物を投入して加熱処理することができ、内部圧力が上昇して通蒸する際に破裂音が発生しにくい加熱処理用包装体を提供する。【解決手段】本発明に係る加熱処理用包装体は、内容物を加熱処理するための包装体であって、内容物を内部に投入して密封するチャックシール部と、前記内容物を加熱処理して内部圧力が上昇したときにその圧力を逃がす合掌シール部とを有し、前記合掌シール部の中央には、前記合掌シール部の包装体内部側及び包装体外部側の両方に非シール部を有するＨ字型シール領域が形成されており、前記Ｈ字型シール領域の両脇には、前記合掌シール部の包装体内部側に非シール部を有する逆Ｕ字型シール領域が形成されている。【選択図】図１
