JPH10316168A - Lid member - Google Patents

Abstract

PROBLEM TO BE SOLVED: To suppress a lid member from curling to the outside by steam, and improve the sealing property by providing a folding-in piece at two locations being confronted to each other in such a manner that the folding-in pieces may protrude from the mouth edge part of a container in the vertical direction to a tab piece of the circular lid member which is bonded on the mouth edge part of the cup-shaped container and closes the container opening part. SOLUTION: For this lid member 10 for a paper cup, etc., containing a food which is eaten by pouring hot water such as an instant noodle, a tab piece 11 in order to make a circular opening for the pouring of hot water, is formed in a manner to protrude from the mouth edge part of a cup-shaped container 20. In this case, in the vertical direction to the tab piece 11, folding-in pieces 12, 13 are provided additionally at two locations being confronted in a manner to protrude from the container mouth edge part. Then, by folding the tab piece 11 and the folding-in pieces 12, 13 at two locations to the container mouth edge part, and they are held by joining, and the outside is prevented from curling. These folding-in pieces 12, 13 are made into a size which can be kept in a square being externally joined to the peripheral edge of the lid member 10, and an efficient layer-out can be performed when the they are provided with multiple surfaces.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover material for a paper cup or a plastic cup, and more particularly to a cover material for a paper cup or a plastic cup into which foods such as instant noodles, instant soup, instant miso soup and the like are poured and heated.

[0002]

2. Description of the Related Art Conventionally, foods such as snack noodles which are poured into boiling water are those in which boiling water is poured into a cup-shaped container to restore the noodles and eat and drink with soups and the like. If the method of use is described in more detail, as shown in FIGS. 4 (a) to 4 (d), the knob 51 is picked up and pulled so as to lift it, and the cover member 50 is pulled to about 1/2 of the container opening. The lid is peeled off and opened, and hot water is poured. Then, the opened portion of the lid material is brought into contact with the upper surface of the lip 22 of the cup-shaped container 20, and the knob 51 is moved to the lip of the cup-shaped container. Is pressed against the side and lower surfaces of the cup, and the opened portion is held in close contact with the rim 22 of the head of the cup. In this state, the user waits for a required time, and after the required time has elapsed, the knob 5
1 is removed from the lip 22 to expose the container opening, and eat and drink contents such as noodles.

[0003] However, the lid material 50 peeled off from the rim portion.
When hot water is injected, it generally curls outward due to steam, resulting in poor adhesion to the lip. Specifically, even if the knob is pressed and folded so as to be folded into the lip, if the folding is weak, the opening may be opened (see FIG. 4C),
Also, even if the knob is folded well, the lid material has a curl property, so that both ends of the knob float and vapor escapes (see FIG. 4D). And so on.

Further, Japanese Utility Model Publication No. 56-31979 discloses a lid plate which is to be attached to the edge of the head of a container such as a noodle cup and peel off one side of a mark line to form a hot water inlet. There is disclosed a lid having a flap in which a portion in the vicinity of the mark line in the portion to be peeled is projected symmetrically on both sides.

The flap protruding from the edge of the container in the present invention is provided to adjust the width of the opening in two steps when the hot water is discharged from the container, and is used to prevent the curling of the lid material. Not for. In addition, there is a problem that the position of the flap is not specified, and the efficiency of the multi-imposition is not good.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate these problems in the prior art. Even if the lid material curls outward due to steam, the lid material does not curl upward. It is an object of the present invention to provide a lid material having good properties and high efficiency when multi-faced.

[0007]

Means for Solving the Problems A first invention of the present invention is:
A circular lid member having a knob piece that is adhered to the rim of the cup-shaped container and closes the container opening, and protrudes from the container rim in a direction perpendicular to the knob piece. Opposing 2
A lid member provided with a folding piece at a location.

According to a second aspect of the present invention, in the first aspect of the present invention, the knob and the folding piece are accommodated in a rectangle circumscribing the periphery of the lid.

[0009] As described above, according to the present invention, the two tabs are vertically opposed to the knob pieces so as to protrude from the edge of the container.
Since the folding piece is provided at the location, the knob piece and the two folding pieces are folded into the edge of the container and held in close contact, so that the lid material can be prevented from curling outward. Furthermore, since the folded piece is large enough to fit in a rectangle circumscribed on the periphery of the lid material, an efficient layout can be achieved when multiple pieces are provided.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments. FIG. 1 is a plan view of a lid member according to the present invention, FIG. 2 is an explanatory view showing a use state thereof, and FIG. 3 is an example of an allocation diagram when imposing the lid member on one sheet.

The lid 10 of the present invention has a circular shape, and a knob piece 11 for forming an opening 21 for pouring is formed so as to protrude from an edge 22 of a cup-shaped container 20.
Further, the folding pieces 12, 1, 2 are vertically opposed to the knob piece 11 so as to protrude from the container edge 22.
3 are provided.

The point is that the folding pieces 12 and 13 have a size that fits in a rectangle circumscribed on the periphery of the lid member 10. This makes it possible to provide an efficient layout when the cover is multi-faced (see FIG. 3).

As a material of the lid member 10, for example, a laminated sheet composed of four layers of paper / polyethylene / aluminum foil / heat-sealable adhesive layer can be mentioned, and it can be thermally bonded to the lip 22 of the cup-shaped container. Any material can be used if it exists.

As shown in FIG. 2, the method of using the cup-shaped container using the lid member is as follows. As shown in FIG. The container is peeled off from the rim 22 of the cup-shaped container and opened, a required amount of hot water is poured into the container, and the opened portion of the lid 10 is brought into contact with the upper surface of the rim 22 of the cup-shaped container, The gripping piece 11 and the two folding pieces 12 and 13 are press-fitted so as to be folded into the side and lower surfaces of the lip 22, and the opened lid portion is closely held to the lip 22 of the container. In this state, the user waits for a required time, and after the required time elapses, removes the gripping piece 11 and the two folding pieces 12 and 13 from the rim 22 to expose the container opening 21 and eat and drink contents such as noodles. I do.

Since the peeled portion of the lid material is pressed into the lip 22 by two folded pieces 12 and 13 in addition to the knob piece 11, the lid material curls outward even when the steam hits the closed lid material. It is difficult to float, and both ends of the opened lid material do not float, and there is little escape of steam.

[0016]

As described above, according to the present invention, since the peeled lid material and the container rim are pressed, the lid material does not curl to the upper surface and the steam of the hot water does not escape to the outside. , The heat retention function is improved. In addition, since the knob piece and the folding piece are set to fit in a rectangle circumscribed on the peripheral edge of the lid material, an efficient layout is possible when multiple mounting is performed, and the material can be effectively used.
