2. Description of the Related Art As shown in Japanese Utility Model Publication No. Sho 62-21581, a lid attached to a container body for accommodating instant noodles is provided with a concave groove provided on an outer peripheral portion thereof at an opening edge of the container body. In most cases, the cover is attached to the container body by fitting it into the flange-shaped part provided in the part. This type of lid heats a thin synthetic resin sheet such as polystyrene or polypropylene. Often manufactured by plate forming. When a large number of such lids are stacked, and the suction tool is pressed against the upper surface of the top lid to adsorb, the suction tool is raised and the lid is taken up. In some cases, two or more sheets may be picked up at a time while the closed lids are fitted to each other via the recessed groove forming portions. Therefore, conventionally, a so-called blocking portion for preventing the concave groove of the upper lid from being fitted into the concave groove forming portion of the lid adjacent to the lower lid in each lid to be stacked. Is provided. In the conventional lid body, the blocking portion is formed on the inner wall portion of the recessed groove except for the location where the drain hole is formed, and the blocking portion protrudes outward from the recessed groove (that is, toward the center of the lid). It was formed by providing a part .

[0003]

By the way, in the above-mentioned conventional lid, the inner wall of the recessed groove and the inner surface of the container body (when the lid is mounted on the container body) are shrunk after the hot plate is formed. There is a problem in that a gap is formed between the two (the inside of the flange-shaped portion) and the fitted state of the two becomes too loose .

[0004] The present invention has been made in view of the above problems, and by devising the bulging direction and the location of the protruding portion serving as the blocking portion, blocking can be reliably performed. It is an object of the present invention to provide a lid for an instant food container in which a recessed groove of a lid can be securely fitted to a flange-shaped portion.

It is manufactured in. The thickness of the cover A is about 0.20 to 0.25 mm. A recessed groove 1 is provided on the outer periphery of the lid A in a substantially rectangular annular shape, and a required number of hot water outlets 2 are opened at two corners in the diagonal direction of the recessed groove 1. ing. Projections 41 to 45 are swelled toward the inside of the recess groove 1 at a plurality of inner wall portions 3 excluding the hot water outlet forming portion A in the recess groove 1. More specifically, as shown in FIGS. 1 and 2, one protruding portion 41 is provided at a predetermined position of the first side 31 on the substantially rectangular inner wall 3, and a predetermined interval of the second side 32 is provided. A total of two protrusions 42 and 43 are formed at two places apart, one protrusion 44 is formed at a predetermined position of the third side 33, and one protrusion 45 is formed at a predetermined position of the fourth side 34, respectively. ing. These projections 4
1 to 45 are respective side portions 31 to 34 provided respectively.
Has a flat planar shape whose width in the longitudinal direction 31a, 32a, 33a, 34a is longer than the width of protrusion into the recessed groove 1.

The outer peripheral edge of a portion (hereinafter referred to as a main body portion) 5 of the lid A surrounded by the recessed groove 1, that is, a portion provided continuously with the inner wall portion 3 of the recessed groove 1 is slightly downward. The protruding ridges 6 are formed in a rectangular ring shape, and the ridges 6 serve as reinforcing ribs to increase the bending rigidity of the entire cover A. FIG.
As shown in (1), a small step a is maintained between the inner surface of the ridge 6 and the inner surface of the protrusion 45, and the step a is formed between the inner surface of the ridge 6 and the inside of the main body 5. It is the same or substantially the same as the step b formed between the surface and the surface.

As shown in FIG. 3, a step c is also formed between the upper surface 51 of the recessed groove and the upper surface 51 of the main body. A bulging portion 7 protruding in the depth direction D of the concave groove 1 is provided at a predetermined position of the main body 5, specifically, as shown in FIGS. Have been. The bulging portion 7 has a protruding portion 42 in which a part thereof, that is, an outer edge surface 71 of the right end (the left end in FIG. 1) of FIG. 2 is provided on the second side portion 32 of the inner wall portion 3 as shown in FIG. At the position close to the outer surface 421 of the projection 42, and the position of the edge outer surface 71 is as shown in FIG.
Is located at a position that is continuous with the second side portion 32 via the. Therefore, as shown in FIG. 3, the distance H1 between the outer surface 71 of the edge of the bulging portion 7 and the outer surface 421 of the protruding portion 42.
Is wider than the distance H between the edge outer surface 71 and the outer surface of the second side portion 32. The intervals between the outer peripheral surface 71 of the bulging portion 7 other than the right end portion (left end portion in FIG. 1) of FIG. 2 and each side portion 31, 33, 34 of the inner wall portion 3 and the protruding portions 41, 43,

The cover A described above is manufactured by hot-plate molding a thin synthetic resin sheet as described above. At this time, the outer peripheral surface 71 of the edge of the bulging portion 7 is The outer surface of the second side 32 and the outer surface 421 of the protrusion 42
Is too close to the bulge 7 as described at the beginning.
And wrinkles such as a bridge extending between the inner wall 3 and the protrusion 42. However, in this embodiment, the edge outer surface 71 of the bulge 7 faces the outer surface 421 of the protrusion 42, and the edge outer surface 71 of the bulge 7 and the protrusion 4
2 is larger than the distance H between the edge outer surface 71 and the outer surface of the second side 32, and the distance H1 is sufficiently large. Even if it is performed, there is no possibility that wrinkles such as a bridge extending between the bulging portion 7 and the protruding portion 42 are generated.

Next, the container main body V is made of a synthetic resin foam such as styrene, and a flange 10
0 is provided. In the lid A attached to the container main body V, the groove width of the concave groove 1 is originally set between the flange 100 of the container main body V and the concave groove 1 when the concave groove 1 is fitted. Although it should be dimensioned so as not to create gaps, it is often the case that small gaps are actually created.
However, as in this embodiment, the protruding portions 41 to 45 are bulged toward the inside of the recessed groove 1 on the inner wall portion 3 of the recessed groove 1, and the flange 100 and the recessed groove 1 are connected to each other. When fitted, the protrusion 42 comes into contact with the inner surface of the container body V as illustrated for the protrusion 42 in FIGS.

A similar effect is exerted by 1, 43, 44, and 45.

By the way, the protrusions 41 to 45 are originally formed by pressing a suction tool on the upper surface of the uppermost lid of a plurality of lids stacked in a multi-stage manner, and then lifting the suction tool to cover the lid. It is provided to prevent blocking when performing an operation of picking up the body. In order for the projections 41 to 45 to exhibit such an anti-blocking action, at least one of the individual projections 41 to 45 is misaligned between two lids stacked on adjacent steps. Alternatively, it is necessary to determine whether the projections are different in size and that the protrusions cannot be fitted to each other between the lids of the adjacent steps. If the two lids stacked on the adjacent step are in a state where the protruding portions cannot be fitted to each other, FIG.
The protruding portion 45 of the upper lid A is supported by the upper surface of the lower lid A at the location where the recessed groove is formed between the two lids A, A stacked in the above manner. Blocking is prevented. The same applies to the other protrusions 41, 42, 43, and 44.

In this embodiment, although the cover A is formed in a substantially rectangular or rectangular shape in plan view, the shape of the cover is not limited to this, and the cover A may have another polygonal shape. The shape may be a circle having a corner portion only at a location.

[0015]

According to the lid of the instant food container according to the first and second aspects of the present invention, blocking when the plurality of stacked lids are picked up by the suction tool is prevented by the projecting portion, and furthermore, the blocking is achieved. The effect of improving the fitting property by the protruding portion provided to prevent the occurrence of the above-mentioned effect also brings about an effect that the fitting property of the recessed groove of the lid to the flange portion of the container body is also improved.
