BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a lid used for packaging containers such as instant noodles, and more specifically, a sheet-like lid used for performing hot water draining after tempering noodles in a container like instant foods such as fried noodles and raw noodles. It is about the body.
[0002]
[Prior art]
Conventionally, containers used by sipping noodles in a container typified by yakisoba or raw noodles and then draining hot water are instant noodles such as fried noodles and bag noodles in a plastic molded container body such as expanded polystyrene, It is generally used in a form that contains ingredients, seasonings, etc., and a plastic molded lid with a notch to be used as a hot water cut hole is fitted to the plastic molded container body and the whole is wrapped in a shrink film Has been.
[0003]
This kind of container has a problem that the operation of attaching and detaching the lid to the container body is troublesome, the operation of raising the notch provided in the lid and securing the through hole is quite troublesome, and the finger is not used when raising the notch with fingers. There are problems such as injuries, and notches for securing through holes can only be formed in part of the flange, so it takes some time to drain the hot water. Although it must be held and drained, there is a risk that hot water may be spilled due to the large amount of hot water required for reconstitution with respect to the capacity of the container. There is a problem that there is a risk, when the hot water drains, the container must be tilted and the hot water must be discharged from the through hole, but a considerable weight of noodles containing hot water is unevenly distributed on one side, so that the lid does not come off from the container body container The body and lid must be pressed with a force greater than the specified level, the fingers get tired and hot, and sometimes the spilled noodles are spilled from the container. However, the container body and the lid are not sealed, and there is a problem that insects or the like may be mixed.
[0004]
In order to solve the above problem, for example, a lid disclosed in Japanese Utility Model Publication No. 61-3810 has been developed. That is, the lid disclosed in Japanese Utility Model Publication No. 61-3810 is composed of a front base material and a back base material, and a half cut (drainage) is formed on the back base material by peeling the front base material. The part of the hot water forming half cut line) is cut out together with the front substrate side to form a hot water outlet, and the hot water is cut from this hot water outlet.
[0005]
However, the lid described in Japanese Utility Model Publication No. 61-3810 has a peeling region between the front substrate and the back substrate, an adjacent non-peeling region adjacent thereto, and an independent non-peeling region within the peeling region. It is necessary to form the hot water outlet forming half cut so as to coincide with the independent non-peeling region, but when forming the hot water outlet forming half cut (half-cut line for forming the hot water outlet) Since the peeling region exists between the front substrate and the back substrate, it cannot be visually confirmed. Since this positioning operation is quite complicated, the productivity is low, and the independent non-peeling region and this If the position of the half cut for forming the hot water outlet (half cut line for forming the hot water outlet) is shifted, a fatal problem that the hot water outlet cannot be formed occurs.
[0006]
[Problems to be solved by the invention]
Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is a sheet-like lid body that has good productivity and can reliably form a hot water outlet. Thus, it is an object of the present invention to provide a sheet-like lid that has excellent sealing properties as a container and can be easily, quickly, safely, and reliably cut off hot water without the need for hot water cutting operations.
