LID-ATTACHED CONTAINER TO BE HEATED IN MICROWAVE OVEN

To provide a lid-attached container which can increase certainty that the lid member is partially peeled off so as to pass steam in the case that the container body is made of paper.SOLUTION: A lid-attached container comprises: a paper container body; and a lid member for sealing the container body. The lid member comprises: a base material layer; a sealant layer; and a heat-generating printing layer in a part between the base material layer and the sealant layer or in a part of the base material on a side opposite to sealant layer. The lid-attached container is sealed with a heat-sealed region formed through heat-seal of a flange and the sealant layer. The lid-attached container is arranged with the heat-generating printing layer in following Region 1 and Region 2, where the is a region connecting a part of an outer peripheral edge of the flange in a circumferential direction to a part of an inner peripheral edge of the flange in the circumferential direction, and the is a region continuous from the Region 1 and inside the inner peripheral edge of the flange.SELECTED DRAWING: Figure 3 【課題】容器本体が紙である場合に蓋材が部分的に剥離して蒸通する確実性を高めることができる蓋付容器を提供する。【解決手段】紙製の容器本体と、前記容器本体を密封する蓋材とを備えてなる蓋付容器であって、前記蓋材は、基材層及びシーラント層を有し、前記基材層と前記シーラント層との間の一部又は前記基材層の前記シーラント層とは反対側の一部に発熱印刷層を有し、前記蓋付容器は、前記フランジと前記シーラント層とがヒートシールされてなるヒートシール領域により密封されてなり、前記発熱印刷層を下記領域１及び領域２に有する、電子レンジ加熱用の蓋付容器。＜領域１＞前記フランジの外周縁の周方向の一部から前記フランジの内周縁の周方向の一部を結ぶ領域。＜領域２＞前記領域１から連続する領域であって、前記フランジの内周縁より内側の領域。【選択図】図３
