Description

  TECHNICAL FIELD The present invention relates to a lid member with a hot water cut hole used for a purpose of performing hot water cutting after opening a lid, injecting hot water and cooking the instant yakisoba in the container, like a container for instant fried noodles.

Conventionally, as in the case of instant fried noodles, as a lid for containers to be used after pouring hot water into a container and cooking the instant fried noodles, A base material and a surface sheet covering the base material are laminated via an adhesive layer, a release region where a release agent is applied between the base material and the surface sheet, and a non-release region disposed in the release region And the other non-peeling region disposed adjacent to the peeling region, and the non-peeling region in the peeling region has a half cut for forming a drain opening, from the base material on the inner surface side. Formed in a range extending to the adhesive layer, and a drain opening opening knob is linearly along the boundary line between the non-peeling region and the non-peeling region disposed adjacent to the peelable region, on the outer surface side From the top sheet to the adhesive layer An adhesive layer is formed from the base material at a position intersecting with the peeling half cut, starting from the outer peripheral end opposite to the peeling half cut, in the vicinity of the knob for opening the hot water outlet. There is known an instant noodle container lid material having a hot water discharge function provided with a half cut for peeling the knob part (see, for example, Patent Document 1). However, in the case of the lid having the above structure, when the consumer uses the container to which the lid is attached, since the opening has a knob for opening and a knob for opening the hot water outlet, Rather than opening the lid, it has the disadvantage of accidentally grabbing and peeling off the hot water outlet opening knob and forming the hot water outlet first, and the printing position of the release agent When the top sheet is peeled off from the base material when there is a shift in the half cut position for forming the hot water outlet opening, the substrate surrounded by the half cut for forming the hot water outlet opening is adhered to the top sheet. In such a case, there is a disadvantage that a predetermined hot water outlet is not formed on the base material.
