Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foamed resin double-walled soup insulation container provided with a heat insulating space between a combination of an inner wall and an outer wall.

[0002]

2. Description of the Related Art Containers of this kind are used, for example, as soup powder, stewed bowls, cups of cup noodles (registered trademark), and the like. The heat insulation space is provided inside by molding both of them and integrating them. Conventionally, for the integration, means for welding the joint at the upper edge by ultrasonic waves has been used.

[0003]

According to the above-mentioned welding means, the welding portion is formed as a joining surface, and the joining surface is melted and joined by ultrasonic vibration. Since it is very difficult to equalize both the vertical and horizontal forces over the entire circumference, gaps and steps are likely to occur due to poor adhesion, and when the inside of the container becomes a seam, There is a problem in that there is a risk of intrusion, and when the outside becomes a seam, it becomes unsightly. A similar problem is also caused by bonding with an adhesive.

The present invention has been made in view of the above-described circumstances,
An object of the present invention is to provide a soup insulation container in which adhesion between an inner wall and an outer wall is accurate and reliable.

[0005]

In order to achieve the above-mentioned object, the present invention provides an inner wall and an outer wall which are molded as a foamed resin and are joined together at their edges so that both walls are assembled. In the soup heat insulation container provided with a heat insulating space between the inner wall and the outer wall, both the inner and outer wall portions face each other at the joint between the inner wall and the outer wall so that the adhesive applied to the portion accumulates by capillary action. A soup warmth container was provided in which a reservoir between surfaces and a reservoir between lateral surfaces were provided, and bonding was strengthened and bonded by shrinkage due to curing of the adhesive in the reservoir.

[0006] According to the above configuration, the full curing of the adhesive in the pool portion not only results in a water-tight barrier block that never leaks, but also applies an adhesive to the pool portion during assembly. When the inner wall and the outer wall are combined, the adhesive fills the pool due to the capillary phenomenon, and the adhesive hardens and shrinks. The pools come close to each other with a vertical force and are bonded and bonded by vertical and horizontal forces. Therefore, accuracy is obtained, and no gaps or steps are formed at the seams.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. The drawing shows an embodiment in which the present invention is embodied as an insulated soup bowl of soup powder or the like. The soup insulated container is composed of a body 1 and a lid 2, each of which has a bowl-shaped inner wall 3 and an outer wall 5 made of urethane foam. And a heat insulating space 7 is provided between them, and the adhesive 6
Is used. In addition, in the case of a cup such as a cup noodle, an embodiment in which there is no lid and only the body is provided. First, the embodiment shown in FIGS. 1 to 3 will be described.

The outer wall 5 has a vertical surface 8a formed on the inner peripheral surface near the edge at a step 9 (see FIG. 3). On the other hand, the inner wall 3 is provided with a step 11 in the middle between the upper and lower sides facing the drawn-in vertical surface 8a. A pool 13 is generated (FIG. 2). In other words, the inside has a vertical surface 8b of the internal wall 3 facing the vertical surface 8a of the external wall 5, and a space 13 therebetween. Further, a hooking portion 17 is provided at the edge of the inner wall 3 to cover the end surface as the lateral surface 15a of the outer wall 5, and a recess 19 is formed on the back side of the hooking portion 17, so that a lateral space pool portion 21 is provided. Inside it has a lateral surface 15b of the inner wall 3 facing the lateral surface 15a of the outer wall 5.

When the inner wall 3 and the outer wall 5 are combined, the adhesive 6 is applied to both sides or one side of the portion that becomes the inter-vertical surface pool portion 13 and the inter-lateral surface pool portion 21 so as to be slightly excessive. Then, the adhesive 6 fills the pool 13 between the vertical surfaces and the pool 21 between the horizontal surfaces generated by the assembly by capillary action. This forms a barrier block, but due to shrinkage due to the curing of the adhesive 6, the two vertical surfaces 8a and 8b are shifted sideways in the vertical surface pooling portion 13, and the two horizontal surfaces 15a and 15b in the horizontal surface pooling portion 21. Accuracy is obtained by tightening the joining force in the vertical and horizontal directions, and the two joining surfaces 23 are strongly pressed against each other and securely adhered without any gap.

The inner walls 3, 3 of the body 1 and the lid 2 have
Ceramics 2 radiating far-infrared rays facing thermal insulation space 7
5 is applied to enhance the heat retaining effect. In addition, the action of far-infrared rays improves the flavor of foods, and the foods warm the body. Next, another embodiment will be described.

The above (FIGS. 1 to 3) are of an independent reservoir type, while the following FIGS. 4 to 6 are of a continuous reservoir type. Also in this case, the body 1 and the lid 2 are each assembled from a bowl-shaped inner wall 3 and an outer wall 5 made of urethane foam, and a heat insulating space 7 is provided between both of them. 3 and the outer wall 5, there is a vertical space 13 and a horizontal space 21.
The formation of 3, 21 is different from that of the above embodiment as follows.

At the end face of the outer wall 5, a step is provided on the inside at a low level, and a recessed groove 31 is formed between the steps. Inside the step, an inner inner peripheral surface is provided at regular intervals along the circumference. , Are provided with projections 33, 33,. Meanwhile, the inner wall 3
As in the above embodiment, a hooking portion 17 is provided at an end of the hooking portion 17. On the lower surface of the hooking portion 17, a ridge 35 is provided so as to be fitted into the gap 31. It is formed so as to match with the peripheral projection 33.

The vertical surface pooling portion 13 is a gap in which the peripheral surface projection 33 is formed as a separate portion, and is formed between the inner peripheral surface of the differential groove 31 and the ridge 35 at the height of the peripheral surface projection 33. In this case, the pool 13 is formed such that the inner side surface of the difference groove 31 is one vertical surface 8a and one surface of the ridge 35 is the other vertical surface 8b. In addition, the pool portion 21 between the lateral surfaces
The hook 17 of the inner wall 3 is formed by the step of the end face of the outer wall 5.
And the lower surface is one side surface 1
5a, the surface of the hook portion 17 facing the other side surface 15b
This reservoir 21 is formed.

In the case of this embodiment, the remainder of the adhesive 6 in the pool 21 between the lateral surfaces advances between the inner peripheral surface of the outer wall 5 and the outer peripheral surface of the inner wall 3, and the space therebetween is vertically separated. Inter-surface pool 13
a. In other words, this vertical surface accumulation portion 13a
The inner peripheral surface of the outer wall 5 and the outer peripheral surface of the inner wall 3 are vertical surfaces 8a, 8b.
It has become. Although the tip of the ridge 35 has a semi-circular cross-sectional shape, the shape may be various such as a wedge as shown in FIG.

[0015]

As described above, according to the present invention, not only does the adhesive form a high-level watertight barrier block, but also the adhesive between the vertical-side pool and the horizontal-side pool is bonded. Due to the overwhelming force of shrinkage when the agent cures, the inner wall and the outer wall are exactly aligned and adhered vertically and horizontally, and gaps between them that cause juice leakage and appearance There is an excellent effect that a high-quality soup insulation container without a step or a step can be provided.
