Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a cylindrical beverage container with a bottom made of paper, plastic film, etc. Regarding the top.

0002

[Conventional technology]

Wrap a slightly thick paper such as cardboard into a hollow cylinder, and wrap it around the inside circumference of the bottom end. Beverage cups, which are formed by pasting together circular bottoms, are commonly used as containers for various beverages. It has been widely known since then.

0003 FIG. 4 is a perspective view of the beverage cup, and FIG. 5 is a cross-sectional view thereof. In these figures , 4 is a drinking cup, 41 is its cylinder, 42 is a disc-shaped bottom, and 43 is a cylinder. This is a ring portion formed by rolling the upper edge of 41 outward. This ring portion 43 This makes the beverage cup 4 strong and does not lose its shape. ing.

[Problem that the idea aims to solve]

By the way, the beverages that can be filled in such a beverage cup 4 include soft drinks. In addition to drinking it chilled, like hot coffee, there are also many drinks that are warmed up, like hot coffee.

[0005] However, in the above-mentioned conventional drinking cup, the drink placed inside the cup is No consideration has been given to keeping the food warm, so drink it warm. It was unsuitable as a beverage cup.

[0006] Also, the fact that internal heat easily escapes to the outside means, conversely, that heat from the outside can easily escape from the inside. This also means that it is easier for the body to pass on to the body, so the opposite is true for well-chilled drinks. The drawback was that it easily warmed up quickly.

[0007] The present invention was developed based on this background, and overcomes the deficiencies of the prior art described above. We aim to provide a drinking cup that solves these problems and improves insulation performance with a simple structure. The porpose is to do.

[0008]

[Means to solve the problem]

In order to achieve the above objectives, the present invention provides an outer side of the inner cup into which the beverage is placed. and at least one outer cup, and an air layer is formed between the two cups. It is characterized by.

[0009]

[Effect]

The cylindrical outer surface of the inner cup, which serves as the beverage container, has a low coefficient of thermal conductivity and has an excellent insulation effect. As long as the top surface of the cylinder is covered with a cap, it will not heat up. Minimizes the heat dissipation of heated beverages and increases heat retention efficiency. Also, chilled beverages The heat transfer from the outside is minimized and the cooling efficiency is increased.

0010 Note that the bottom of the inner cup is located slightly above the lower edge of the cylinder, and the bottom of the outer cup is If an air layer is formed between it and the bottom of the side cup, the insulation efficiency will be even higher. .

[0011]

【Example】

Next, an embodiment of this invention will be described based on the drawings.

0012 FIG. 1 is an exploded perspective view of a beverage cup according to this embodiment, and FIG. 2 is an exploded perspective view of the beverage cup according to this embodiment. 3 is an enlarged view of section A in FIG. 2.

[0013] As shown in FIG. 1, the beverage cup according to this embodiment includes an inner cup 1 and an intermediate cup. It consists of a cup 2 and an external cup 3.

[0014] The internal cup 1 is formed by wrapping relatively thick paper such as cardboard or kraft paper. The inner periphery of the cylinder 11 is placed inside the cylinder 11 at a position slightly above the lower edge 13. Reinforcement provided at the upper edge of the disk-shaped bottom 12 and the cylinder 11, which are closely bonded to each other. It is composed of a ring part 14 for use.

[0015] The intermediate cup 2 is composed of a cylinder 21 made of corrugated paper wound together. As clearly shown in FIG. 3, this cylinder 21 has valleys 23 and peaks 24 that are arranged alternately. It has a corrugated shape, and as shown in Figure 1, vertical grooves 22 are formed in parallel at equal intervals. ing.

[0016] The external cup 3 is also made from a cylinder 31 made of rolled cardboard, kraft paper, etc. It is configured.

[0017] The material for each cup 1, 2, and 3 can be paper, plastic, or synthetic paper. good.

[0018] As shown in FIG. 2, the cylinder 11 of the inner cup 1 is inside the cylinder 21 of the intermediate cup 2. The cylinder 21 of the intermediate cup 2 is fitted onto the circumferential surface of the cylinder 3 of the outer cup 3. 1, but as shown in FIG. The inner peripheral surface of the cylinder 31 is brought into contact with the crest 24 of the cylinder 21. By doing so, the inner cup 1, intermediate cup 2, and outer cup 3 are fixedly held. can be done.

[0019] As described above, the cylinder 21 of the intermediate cup 2 has valleys 23 and peaks 24 alternately. Since the grooves 22 are continuously provided, the overall shape is wavy, and the grooves 22 are formed continuously. However, as shown in FIG. 3, the groove 22a formed between the valleys 23, 23 is cylindrical An air layer is formed between the outer peripheral surface of 11, and similarly, an air layer is formed between the peaks 24, A space layer is also formed between the groove 22b and the inner peripheral surface of the cylinder 31.

[0020] Therefore, the cylinder 11 of the inner cup 1 that accommodates the beverage is not directly exposed to the outside air. It is surrounded by an air layer formed by the grooves 2a and 2b. Therefore, If the ring part 14 is covered with a cap (not shown) to completely cover the top surface, the internal The insulation efficiency for beverages can be increased. In addition, the external cup 3 has a bottomed shape. Since the bottom 12 of the inner cup 1 is slightly above the lower edge 13, the outer cup An air layer can also be formed between the bottom of the cup 3, and in that case, the insulation effect is further improved. It will increase the fruit.

[0021] In addition, in this embodiment, the outer cup of the inner cup 1 into which the beverage is directly poured is , two are provided, an intermediate cup 2 and an external cup 3, but the main point is that the internal cup 1 All you need to do is surround the outside of the cup with an air layer that has an insulating effect, so there is only one type of outer cup. or, conversely, there may be three or more types.

[0022] In addition, in this embodiment, the vertical groove 22 of the corrugated intermediate cup 2 is used to create an air layer. However, this groove 22 may be formed in the horizontal direction, or In addition, the air layer may be formed by various configurations other than the groove.

[0023]

[Effect of the idea]

As mentioned above, according to the beverage cup according to this invention, the inner cover that serves as the beverage container is It has a simple structure that includes a cup and an outer cup, and forms a space layer between them. It can insulate beverages, increasing the heat retention effect for hot beverages. In addition, it is possible to improve the cooling effect for cold beverages.
