[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid which is placed on a cup-shaped container which stores food in a sealed state, and more particularly to a lid which is used for a food container which is heated and cooked in a microwave oven after opening. .

[0002]

2. Description of the Related Art In recent years, ready-to-eat foods cooked in a microwave oven in a container have become widely used. As such a container, a cup-shaped container storing food is sealed with a lid material laminated with aluminum foil or the like at the opening, and further covered with a heat-resistant resin lid having a vapor hole from above. I have. In other words, when heating with the lid material sealed, the pressure in the container rises and the container ruptures, causing a situation in which food is scattered in the microwave oven. The lid is put on again and heated.

[0003]

The lid made of a heat-resistant resin as described above can release pressure from the vapor hole at the time of heating, but requires post-processing by punching the vapor hole into the molded lid. There was a problem that the manufacturing cost was high.

The present invention has been made in view of the above problems, and has as its object to reduce the manufacturing cost without the need for post-processing for forming a steam hole. To provide a lid that can be used.

[0005]

In order to achieve the above object, according to the present invention, food is stored in a sealed state, and a lid material is peeled off.
Cup that is cooked in a microwave after opening
A lid made of a heat-resistant resin to be put on a container, comprising a cylindrical side wall portion and a top plate portion , wherein the side wall portion has at least one convex portion which bulges outward to a lower end of the side wall portion. Together with the cup-shaped container when placed on the cup-shaped container
The rib that contacts the opening edge of the
A plurality of ribs are provided across the side wall portion and the top plate portion, and the ribs
It is those lower end of the is characterized in that so as to be positioned below the upper end of the convex portion may be provided with a projection for spoon attached to the back side of the top plate.

[0006]

When the lid of the present invention having the above-mentioned structure is removed and the lid of the cup-shaped container storing the food is peeled off and then re-covered, the lower end of the rib comes into contact with the opening edge of the container so that the convex portion is formed. It is in a state of communicating between inside and outside. Then, when heated in a microwave oven in this state, the convex portions serve as steam holes, and act to release steam generated during heating.

[0007]

1 to 3 show a lid as an embodiment of the present invention. FIG. 1 is a top view, FIG. 2 is a bottom view, and FIG. 3 is a sectional view taken along line AA of FIG.

The lid 1 is made by injection molding of a heat-resistant resin, and has a disk shape comprising a cylindrical side wall 2 and a top plate 3 as shown in FIGS. The side wall portion 2 is provided with three convex portions 4 bulging outward to the lower end thereof at equal intervals at three locations. The side wall portion 2 and the top plate are formed so as to avoid the convex portions 4. Six ribs 5 are provided over the connecting portion of the portion 3. The top plate 3 has a shallow depression 3a over substantially the entire area for attaching a label.
Is provided.

A convex portion 4 formed by bulging a part of the side wall portion 2
The upper end of the rib 5 is provided in a shape extending to the vicinity of the top plate portion 3, while the rib 5 is provided in a shape in which the lower end is located below the upper end of the convex portion 4. Further, on the inner periphery of the side wall 2, a horizontally long ridge 6 is provided below the lower end of the rib 5,
In the middle of each rib 5 and 6
It is provided in three places. The ridge 6 serves to prevent the lid 1 from being disengaged by covering the cup-shaped container and engaging the edge of the container when the rib 5 comes into contact with the opening edge of the container.

Here, as shown in FIG. 3, it is preferable that the side wall portion 2 has a taper that spreads downward. This makes it easier to cover the lid 1 on the container, and when the lids 1 are stacked, the adjacent lids 1
As a result, they are separated from each other, so that a good stacking property can be obtained.

Further, in the lid 1 of the present embodiment, a spoon is attached to the back side of the top plate 3. That is, two appropriately-shaped protrusions 7 having hook portions 7a at the lower ends extend inward and downward from the top plate 3 with a length that does not reach the lower ends of the ribs 5, as shown in FIG. A spoon S of a type for connecting the handle portions is engaged with the projection 7. It is sanitary if the spoon S is engaged with the projection 7 in a state of being put in a film bag. The top plate 3 has a hole a at a position corresponding to the hook portion 7a of the projection 7. This hole is formed by the convenience of a mold used at the time of molding. By sticking a label having a barrier property to the depression 3a of FIG.

The above-mentioned lid 1 is put on a sealed container for microwave cooking, and the container is provided for sale in a form integrated with the lid 1 in this way. Then, when cooking by heating, the lid 1 is once removed from the container, the container is opened by peeling off the lid material for sealing and sealing the container, and then the lid 1 is put on the container again. Heat. In addition,
In the case of attaching the spoon S like the lid 1 of the present embodiment, the spoon S is removed when the lid 1 is removed.

When the lid 1 is put on the opened container, the lower end of the rib 5 contacts the opening edge of the container, and the ridge 6 on the inner peripheral surface of the side wall 2 engages with the edge of the container, so that the lid 1 is attached to the container. Fit in
The inside of the container and the outside communicate with each other by the convex portion 4. The steam generated when heated in a microwave oven in this state is
The food is cooked without the pressure in the container becoming excessive.

In the above-described embodiment, an example has been described in which the projection 7 is provided on the back side of the top plate 3 of the lid 1 to attach the spoon S. However, in the case of food that does not require a spoon, When the spoon S is separately prepared, it is not necessary to provide such a projection 7.

[0015]

As described above, the lid of the present invention can be removed by peeling off the lid material of the cup-shaped container for cooking the microwave oven in which the food is hermetically sealed, and then re-covering the lid. Since the convex portion contacts the inside and the outside of the container by contacting the edge, the vapor hole is formed by the convex portion without punching and forming the vapor hole after molding, so the manufacturing cost is reduced. Can be achieved.
