Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid for an instant food container cooked with hot water, and more particularly to a lid which does not use a metal foil such as an aluminum foil as a constituent material.

[0002]

2. Description of the Related Art Conventionally, instant foods represented by cup noodles are prepared by simply pouring boiling water into a cup-shaped container and waiting for a few minutes to restore the noodles, and then eating and drinking the restored noodles together with soups and the like. They are eaten in large quantities because they are easy to do. To describe its use in more detail, for example, in the case of cup ramen, remove the transparent shrink film wrapping the container, and then hand-pinch the knob of the lid material that has been thermally bonded to the container body. And lifted up, peeled off the lid material from the container body to about 1/2 of the container opening and opened it, and in some cases, removed the ingredients and soup attached to the noodles from the packaging bag and put them on the noodles, Next, pour the hot water into the container body from the opened portion, and then contact the opened portion of the lid material with the upper surface of the flange portion of the container body, and place the knob on the container body so that the lid material does not roll up. Fold it on the side and bottom of the flange part, put a weight on the lid material, or hold the knob piece to the container body with tape so that the heat inside the container does not escape, After cooking for the required time in the state Material to be food noodles from the container opening exposed removed from the container body together with the soup or the like.

[0003] By the way, a laminated material composed of paper / aluminum foil / polyethylene / heat-adhesive adhesive layer is generally used as a lid material for such an instant food container. The reason for this is to make the lid member plastically deformable by using aluminum foil in the laminated material. That is, by using a lid material using aluminum foil in the laminated material in this way, a knob of the lid material that is thermally bonded to the container body to pour boiling water is picked up by a finger and turned up to open the container opening. This is because, when the lid is peeled off from the container body to about 1/2 of the case and opened, the lid can be kept in a rolled-up state, and hot water can be easily poured.

However, in recent years, as environmental problems have been highlighted, the use of aluminum foil for laminated materials that are difficult to separate and collect has become a problem. Therefore, we will consider alternative materials for aluminum foil.However, there is no material that has the same plastic deformability as aluminum foil as a lid material that can hold the rolled-up state when pouring hot water. It is the current situation.

A lid made of a laminated material that does not use aluminum foil as a constituent material generally has elastic deformability, and a finger piece of the lid, which is thermally bonded to a container body for pouring hot water, is picked up by a finger. And roll it up to about 1 /
Even if the lid is peeled off from the container body to about 2 and opened, if the knob is released, the lid with elastic deformation returns to its original state so as to close the opened container opening. It is necessary to fix the lid material opened with a weight or tape etc. so that it does not return to the original position and pour boiling water.This type of lid material is extremely inconvenient and unstable and burns due to boiling water etc. There was also a problem in terms of safety.

One solution to this problem is to provide a-(minus) notch at the end of the lid facing the knob, and peel off the container from the container body to pour hot water into the notch and open it. It is a method to prevent the lid material from returning to the original state by inserting the knob piece of the lid material,
With this method, the hot water can be safely and reliably poured into the container because the lid material is fixed so as not to return, and the above problem can be solved, but this method inserts a knob piece into the notch This operation is quite troublesome, and when pouring hot water and cooking for the required time later, it is necessary to remove the knob from the cut again, and this operation is quite troublesome, and in actual use it is operable. There was a problem in the point.
