Description

  The present invention relates to a lid material for a container for storing contents that need to be drained when cooking, such as instant fried noodles and instant ramen, which are prepared by pouring hot water.

  Traditional noodle-type instant ramen and instant fried noodles that are cooked by pouring hot water require a hot water drain (hot water) when cooking, and a hot water cut hole is formed in part of the lid. There are many things.

  For example, instant yakisoba uses a container 65 as shown in FIG. The lid member 60 has an unsealing tab 61 for unsealing the lid member, and a hot water cut hole for peeling off a part of the lid material in a peripheral region opposite to the unsealing tab 61 and causing a hot water cut hole to appear. Forming tabs 62 and cut lines 63 are formed. A hot water cut hole 64 communicating with the inside of the container body as shown in FIG. 13 is formed by picking the hot water cut hole forming tab 62 and peeling the hot water cut hole forming region along the cut line 63. It is.

  When eating the contents, the following operations are generally performed. After pulling the opening tab 61 in the opening direction, opening the lid 60 from the container body to the vicinity of the center to form an opening, taking out a sachet of seasonings, etc., and adding seasonings as necessary Then, hot water is poured, and then the opened lid is placed over the opening and resealed, and steamed cooking is performed. Thereafter, the hot water cut hole forming tab 62 is picked, the hot water cut hole forming region is peeled off to make the hot water cut hole 64 appear, and hot water is cut off, and then the opening tab 61 is picked to peel the lid from the container body. And eat the contents.

  Such work is cumbersome and burdens consumers. In addition, when hot water is contained in the container main body, there is a problem that there is a risk of burns if the hot water hole is made to appear.

  The following proposals have been made for such problems. Opening pull tab protruding outward on the outer peripheral edge of the lid body, and a semi-elliptical hot water cutting opening having a plurality of hot water cutting openings in the vicinity of the inner periphery of the outer peripheral edge facing the opening pull tab. There is a proposal that includes a pull tab provided in a state where the arc-side tip of the hot water cut pull tab is within a seal region to the container flange (Patent Document 1).

  When the circular arc portion is placed on the container flange portion, even when hot water is filled in the container, the hot water outlet pull tab can be peeled off without feeling particularly hot. However, there is a difficult problem in positioning the arc portion on the flange portion. For example, if it shifts inward from the flange portion, the hot water is felt and there is a risk of burns. Moreover, there is a problem that it is mistaken for a pull tab for opening if it is shifted outward from the flange portion.

  Further, the lid material has a structure in which the outer lid and the inner lid are laminated so as to be peelable through the release layer, and has a knob portion protruding outward on the outer peripheral edge. A peeling start cut is formed in the vicinity, a hot water cut hole cut is formed in the center side from the peeling start cut, and an arc shape or a circle that protrudes to the side of the symmetrical knob crossing the line connecting the knob and the center of the lid. There is a proposal in which a shape-shaped inner lid break is formed, and a release layer is formed in a region surrounded by the separation start break, the inner lid break, and the periphery of the lid member (Patent Document 2).

Pulling the knob in the opening direction to form a hot water cut hole and an opening at the same time, which is intended to reduce cumbersome work, but to peel off the lid from the container body and then pour hot water to cook In addition, there is a problem that steam cooking cannot be performed and the quality of the contents is deteriorated.

  There is a demand for a lid material that can be handled safely and does not reduce the cooking effect during hot water cutting.
