SOLUTION: This tableware accepts food, soup, and the like, consists of a metal inner container 1 and an external container 2 made of a synthetic resin, the inner and outer containers 1 and 2 are joined at an upper end, and at the same time a hollow part 3 is formed between the inner and outer containers 1 and 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tableware for holding food and soup.

[0002]

2. Description of the Related Art Conventionally, metal (stainless steel) tableware has been proposed as a tableware for holding food and soup, but it has a drawback that it cannot be held when a hot thing is put in. There are drawbacks, such as the appearance of a metallic color, which makes it feel cold.

[0003] The present invention is to provide a tableware which solves such disadvantages.

[0004]

The gist of the present invention will be described with reference to the accompanying drawings.

[0005] A tableware for holding food, juice, etc., comprising a metal inner container 1 and a synthetic resin outer container 2, wherein the inner container 1 and the outer container 2 are joined at an upper edge, and The present invention relates to a tableware characterized in that a hollow portion 3 is formed between an inner container 1 and an outer container 2.

Further, in the tableware according to the first aspect, the upper edges of the inner container 1 and the outer container 2 are joined by a wrapping process.

[0007] Further, in the tableware according to any one of claims 1 and 2, a projection 4 which is in contact with the outer surface of the inner container 1 is formed at a predetermined position on the inner surface of the outer container 2. It relates to tableware.

[0008] The tableware according to any one of claims 1 to 3, wherein the inner container 1 is made of stainless steel and the outer container 2 is made of polypropylene resin.

[0009]

Since the present invention comprises a metal inner container 1 and an outer container 2 made of synthetic resin, it has excellent heat insulating properties as compared with metal tableware. Since the hollow portion 3 is interposed between the outer container 2 and the outer container 2, the heat insulating property is further improved by the hollow portion 3.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS The drawings are one embodiment of the present invention,
This will be described below.

The tableware according to the present embodiment is a tableware for school lunch, in which an inner container 1 made of stainless steel (SUS 304) and an outer container 2 made of polypropylene are arranged with a hollow portion 3 interposed therebetween. Both upper edges are rolled together and polymerized. In the case of the present embodiment, the temperature difference between the inner surface of the inner container 1 and the outer surface of the outer container 2 is set to be 20 ° C. or more.

A ridge 4 serving as a protrusion is integrally formed on the bottom and side portions of the inner surface of the outer container 2, and the ridge 4 is in contact with the outer surface of the inner container 1. In addition to the case where the protrusion 4 is formed by forming the protrusion 4 in the horizontal direction as shown in FIGS. 1 to 3, the protrusion 4 is formed by forming the protrusion 4 vertically and horizontally as shown in FIG. 4. In the case where the projections 4 are formed in a state where the projections 4 are interspersed as shown in FIG. 5, or when the projections 4 are formed in a state where the projections 4 intersect as shown in FIGS. Any configuration that exhibits the characteristics of the present embodiment, such as a configuration or a configuration in which the ridges 4 are formed in a V shape as illustrated in FIGS. 8 and 9, can be appropriately adopted. In addition, the protrusion 4 may be provided at the bottom and the side of the outer surface of the inner container 1.

Reference numeral 5 denotes a ground leg.

Since this embodiment is constructed as described above, it has the following functions and effects.

1 Because of the two-layer structure of the inner container 1 and the outer container 2, compared to the conventional metal tableware having a single-layer structure, it has excellent heat insulation properties, and it is difficult to hold even a hot dish. Does not occur.

Further, since the outer container 2 is not entirely metal but has a synthetic resin portion (outer container 2) in appearance, the outer container 2 is appropriately colored to eliminate the unique coldness of the metal tableware. And the commercial value will be significantly increased.

Further, because of the double structure of the inner container 1 and the outer container 2, there is no problem that the environmental hormones in the tableware of one layer of synthetic resin elute into the food.

2 Since the inner container 1 and the outer container 2 are polymerized by the entanglement process at the upper edge thereof, the intrusion of water into the inside is prevented, and the durability and hygiene are excellent.

3 Since the hollow portion 3 exists, the heat insulating property is further improved, and the thickness of the outer container 2 made of synthetic resin can be made thinner accordingly. Therefore, the outer container 2 is lightweight and the resin portion is thin. Therefore, even if tableware is piled up, it becomes a tableware that is not bulky and excels in storage.

Further, since the hollow portion 3 exists, the inner container 1 and the outer container 2 are separated well, and the recyclability is improved accordingly.

4 Since there is not a hollow layer between the outer surface of the inner container 1 and the inner surface of the outer container 2 but a ridge 4 (projection), the ridge 4 performs a reinforcing action, and Tableware with excellent durability.

5. Since no adhesive or the like is used for the polymerization between the inner container 1 and the outer container 2, adverse effects due to the adhesive or the like, for example, outflow of environmental hormones do not occur, and the security of the tableware can be ensured. Become.
