Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper lid that fits over the lip of a round container body.

[Conventional technology]

As a paper lid for a round container, an inner rib is provided on the inside of the upper edge of the lid peripheral wall as in Japanese Utility Model Publication No. 52-10679,
The lower half of the peripheral wall is folded inward and the top plate is held between the folded piece and the inner rib.
As in Publication No. 50981, a hanging piece is provided on the outer edge of the top plate,
This hanging piece is attached to the surrounding wall, or
It is known that the lower part of the lid circumferential wall is folded inward and a hanging piece provided at the outer edge of the top plate is held between this folded piece and the circumferential wall, such as in Japanese Patent No. 59-27404 and Japanese Utility Model Application Publication No. 55-61506. . This paper lid is either directly fitted to the main body of the container containing the product, or a resin film is heat-sealed to the rim of the container containing the product and then fitted thereto.

[The problem that the idea aims to solve]

Among the paper lids for round containers mentioned in the prior art, paper lids that hold the top plate between the inner rib and the folded piece on the peripheral wall have the problem that the top plate tends to fall off, and the outer edge of the top plate In the case of a paper lid with a hanging piece, if the outer periphery of the top plate is bent downward all the way around to form the hanging piece, there is a problem that numerous vertical wrinkles will occur around the entire circumference of the hanging piece. Moreover, when the hanging pieces were glued to the peripheral wall, there was a problem that the glue leaked out and became unsightly.

Furthermore, when a pouch containing condiments such as sugar is attached to a paper container for storing food and beverages in addition to containing the product, there is a problem with the location of the pouch.

The present invention was developed in view of the problems of the prior art, and its purpose is to provide a paper lid that does not allow the top plate to fall off and creates a space under the top plate. It's about doing.

[Means to solve the problem]

In order to achieve the above object, the paper lid of the present invention is provided with a bulge on the inside of the upper edge of the inner ring body, and an inner rib on the inside of the upper edge of the outer ring that is fitted on the outside of the bulge. The lower end of the outer wall of the outer ring, which is folded inside the inner ring, holds the top plate between the outer ring and the inner rib.
The inner ring body cannot be removed, and a space corresponding to a bulge is created under the top plate.

[Effect]

Since the top plate is held between the bulge of the inner ring and the inner rib of the outer ring, the holding width is wide.

Since the bulge of the inner ring projects inward, the bulge engages the rim of the container body, creating a space between the top plate and the rim of the container.

〔Example〕

Hereinafter, the structure of the paper lid according to the present invention will be explained with reference to drawings of embodiments. The paper lid 1 includes an inner ring body 2, an outer ring body 4 that fits on the outside of the inner ring body 2, and a bulge provided on the inner periphery of the upper edge of the inner ring body 2. 6 and an inner rib 7 provided on the inner periphery of the upper edge of the outer ring body 4.
is wound around the inner periphery, and a bulging part 6 is provided on the inner periphery of the upper edge,
The outer ring body 4 is wider than the inner wall 3 and has the upper end 5a of the outer wall 5, which is one size larger, rolled inward to form an inner rolled rib 7 on the inner periphery of the upper edge.
The lower end 5b of the outer wall 5 is folded back inside the inner wall 5, and the inner wall 3 is irremovably held by the folded lower end 5b. The top plate 8 has a disc shape, and is fitted between the inner rib 7 of the outer ring body 4 and the inner ring bulge 6, and the outer edge of the top plate 8 is widely held and cannot be removed. A space A that is opposite to the thickness of the bulge 6 is formed below the bulge 8 .

The inner ring body 2, outer ring body 4, and top plate 8 that constitute the paper lid 1 are made of elastic paperboard or waterproof paper.

Since the paper lid of the present invention has the above-mentioned structure, the inner wall 3 and the outer wall 5 which is wider and one size larger than the inner wall 3 are formed in advance.
The upper ends 3a and 5a of both peripheral walls 3 and 5 are rolled inward, and the inner ring body 2 has a bulge 6 inside the upper edge of the inner wall 3, and the upper edge of the outer wall 5. An outer ring body 4 having an inner rib 7 provided therein is formed,
First, turn the top and bottom of the outer ring body 4 upside down, insert the top plate 8 into the outer ring body 4 from above, then insert the top plate 8 with the top and bottom of the inner ring body 2 upside down, and use the inner ring body 2 to insert the top plate 8 into the outer ring body. Push it in until it locks onto the inner rib 7 of 4.
A top plate 8 is held between the inner rib 7 and the bulging part 6.

Next, the lower end 5b of the outer wall 5 protruding from the inner ring 2 is folded back inside the inner wall 3, and the folded lower end 5b makes the inner ring 2 unremovable.

The paper lid 1 of the present invention is fitted until the bulge 6 of the inner ring body 2 that holds the top plate 8 comes into contact with the rim b of the container body B, and the bulge 6 is fitted between the top plate 8 and the rim b of the container. A space A corresponding to the thickness of the protrusion 6 is formed. In the case of a container body B in which a resin film C is heat-sealed to the rim b of the container, a small bag D containing seasonings, a spoon, etc. are placed in the space A.

[Effect of idea]

Since the paper lid of the present invention is constructed as described above, it produces the following effects.

Since the outer periphery of the top plate is widely held between the bulging part of the inner ring body and the inner rib of the outer ring body, it will not fall off even if downward pressure is applied to the top plate. Moreover, after the inner ring body is inserted into the outer ring body, it cannot be removed by simply folding the lower end of the outer wall that protrudes from the inner ring body inside the inner ring body, so there is no need for gluing, and the peripheral wall forms a three-layer structure. This not only dramatically improves durability, but also improves appearance as the outer wall does not wrinkle.

In addition, the bulging part of the inner ring not only helps in holding the top plate, but also forms a space between the top plate and the rim of the container, so this space can be used to hold small bags of sugar, spoons, etc. can also be stored.
