[Solution] The tableware, which is at least one of a dish, a dish holder, or a food utensil used on a dining table, is characterized by comprising a dish body 10 made of a resin or rubber material, and an external colored portion dyed with a dye on the surface of the dish body.

Description

[Technical Field]

[0001] The present invention relates to tableware that is used on a dining table as a dish, dish holder, or food container. [Background technology]

[0002] Tableware made from resin is widely used because it is durable and lightweight. There are two ways to color resin tableware: internal coloring, in which a colorant is mixed into the resin before molding (Patent Documents 1 and 2), and external coloring, in which only the surface of the resin after molding is colored (Patent Document 3).

[0003] Internal coloring allows colored tableware to be obtained during molding, making it suitable for mass production. However, internal coloring requires changing the molding machine for each color, making it unsuitable for small-lot production.

[0004] External coloring is usually performed by painting a colored synthetic resin paint on the surface of the resin after molding, as in Patent Document 3. This eliminates the need for color changes on the molding machine and is suitable for small-lot production. However, external coloring by painting has problems such as the risk of the paint film peeling off and fading, and the thickness of the paint film changing. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0013] <1> tableware In this specification, tableware refers to a dish, dish holder, or food serving implement used on a dining table. A vessel is an implement for placing or containing food or drink, and examples thereof include, but are not limited to, bowls, teacups, glasses, plates, and bowls. The container support is a device that supports the container to prevent it from falling over, and is not particularly limited, but examples thereof include devices that support the outer surface of the container. Food pick-up tools are tools used to pick up food from a dish, and include, but are not limited to, chopsticks, spoons, forks, etc.

[0014] <2> Tableware body The tableware body is made of a resin or rubber material, and may include a portion made of a resin and a portion made of a rubber material. Examples of resins include, but are not limited to, phenol, urea, melamine, unsaturated polyester, polyethylene, polypropylene, polystyrene, acrylonitrile butadiene styrene (ABS), methacrylate, polyvinyl chloride, polycarbonate, polybutylene terephthalate (PBT), polyethylene terephthalate (PET), silicone, acrylonitrile styrene (AS), polyurethane, and vinyl chloride. The rubber material is not particularly limited, but examples thereof include rubber, elastomer, and rubber-like soft resin.

[0015] <3> External colored part The dye used in the external coloring portion is not particularly limited as long as it can dye the surface of the resin or rubber material. The external colored portion is a type of the external coloring described above, but does not exclude the dish body having a color (e.g., white, gray, etc.) different from that of the external colored portion. [Example]

[0016] The present invention will be described with reference to the accompanying drawings, in which: the structures, materials, numerical values, shapes, and dimensions shown in the embodiments are merely examples and may be modified as appropriate without departing from the spirit and scope of the invention.

[0017] [Examples 1 and 2] 1 to 3 show a bowl 10 of a first embodiment and a bowl support 1 of a second embodiment.

[0018] The bowl 10 includes a bowl body molded into a bowl shape from melamine resin, and an external colored portion formed by dyeing the surface of the molded bowl body with a dye.

[0019] The bowl support 1 includes a bowl support body and an external colored portion dyed with a dye on the surface of the bowl support body. The bowl support body consists of a cylinder 2 (resin portion) molded from polyvinyl chloride resin, and three rings 3 (rubber portion) molded from a rubber material and wrapped around the top, outer, bottom, and inner surfaces of the cylinder 2 at three locations spaced equally around the circumference (central angle of 120 degrees). The top surface is sloped downward toward the inside. The portion of the rings 3 that covers the top surface forms the support portion 4, and the portion that covers the bottom surface forms the anti-slip portion 5. Alternatively, four rings 3 may be provided at four locations spaced equally around the circumference of the cylinder 2 (central angle of 90 degrees).

[0020] The external colored portion is formed by dyeing the surface of the molded cylindrical body 2, and also by dyeing the surface of the molded ring 3. The external colored portion can be formed by dyeing using, for example, a disperse dye and a carrier agent. Regarding the color types, for example, yellow can be obtained using Nippon Kayaku's disperse dye "Product Name: KM Yellow AQ-LE," red can be obtained using the same "Product Name: KM Red AQ-LE," and blue can be obtained using the same "Product Name: KM Blue AQ-LE." An example of a carrier agent is Meisei Chemical Industry's "Product Name: Melyer TWF."

[0021] The external colored portion may be a single color for the entire bowl 10, or may be a plurality of colors that are color-coded for different parts of the bowl 10 (for example, the outer part of the bowl may be blue and the inner part of the bowl may be red). The external colored portion may be a single color for the entire bowl support 1, or may be a multi-colored portion with different colors for different parts of the bowl support (for example, the bowl support body may be red and the rubber may be blue).

[0022] (Action and effect) In Examples 1 and 2, the coloring is applied externally by attaching a colorant to the surface of the molded resin or rubber material, so there is no need to change the color of the molding machine for the bowl body, bowl support body, and ring, making them suitable for small-lot production. Moreover, because the external coloring is applied to the surface of the resin or rubber material with a dye, it does not peel off like a paint film, so the color is resistant to fading and there is no change in thickness.

[0023] 3, when bowl support 1 of Example 2 is placed on table 11 and bowl 10 of Example 2 is supported at three circumferentially spaced locations on three support parts 4 that are circumferentially spaced apart in a plan view, bowl 10 is less likely to float from support parts 4 and is less likely to rattle. Furthermore, because support parts 4 are made of rubber, bowl 10 is less likely to slide relative to support parts 4. Therefore, when young children or people with reduced motor skills use a spoon or chopsticks to eat rice, soup, etc. in bowl 10 supported as described above, even if they push bowl 10 sideways with the spoon or chopsticks, bowl 10 will not fall over, so they can eat safely. In addition, rubber anti-slip part 5 prevents bowl support 1 from sliding sideways against dining table 11.

[0024] [Example 3] 4 and 5 show the bowl support 21 of the third embodiment together with the bowl 10 of the first embodiment.

[0025] Like the bowl support 1 of Example 2, the bowl support 21 includes a bowl support main body and an external colored portion dyed with a dye on the surface of the bowl support main body. The bowl support body includes a cylindrical body 22 molded from vinyl chloride resin, similar to the bowl support body of Example 2, and a ring 23 molded from a rubber material, as well as hook-and-loop fasteners 24a and 24b that detachably attach ring 23 to the inner surface of cylindrical body 22. The hook-and-loop fasteners consist of a male and a female, one of which, 24a, is attached to the inner surface of cylindrical body 22, and the other, 24b, is attached to both ends of ring 23, engaging the two together.

[0026] The lower end of the cylinder 22 forms a reduced diameter section 25 that is bent inward, and the opening diameter of the reduced diameter section 25 is relatively smaller than the opening diameter of the upper end. The lower surface (flat surface) of the reduced diameter section 25 is the lower end surface of the cylinder 22. The upper end surface of the cylinder 22 is a slope that becomes lower toward the inside. The portion of the ring 23 that covers the upper end surface forms the support section 26, but becomes a non-slip section when the cylinder is turned upside down, and the portion that covers the lower end surface forms the non-slip section 27, but becomes a support section when the cylinder is turned upside down.

[0027] The external colored portion is formed by dyeing the surface of the molded cylindrical body 22, and also by dyeing the surface of the molded ring 23. The external colored portion may be similar to that in the first and second embodiments.

[0028] In addition to the same effects as those of the first embodiment, the third embodiment also has the following effects. The opening diameter at the top is relatively large, so that it can support a relatively large bowl 10 when not turned upside down as shown in FIG. Since the opening diameter at the bottom is relatively small, it can support a relatively large bowl 10 when turned upside down as shown in FIG. As shown in FIG. 4, the ring 23 can be removed from the cylindrical body 22 by releasing the hook-and-loop fasteners 24a and 24b, which makes it easier to clean the ring 23 and the cylindrical body 22.

[0029] [Example 4] FIG. 6 shows a bowl support 31 according to a fourth embodiment.

[0030] Like the bowl support 1 of Example 2, the bowl support 31 includes a bowl support main body and an external colored portion dyed with a dye on the surface of the bowl support main body. The bowl support body consists of a cylindrical body 32 molded from the same vinyl chloride resin as the bowl support body of Example 2, support parts 33 molded from a rubber material and fitted into three recesses formed on the upper end face of cylindrical body 32 at equal circumferential intervals (central angle of 120 degrees) and protruding from the upper end face, and anti-slip parts 34 molded from a rubber material and fitted into three recesses formed on the lower end face of cylindrical body 32 at equal circumferential intervals (central angle of 120 degrees) and protruding from the lower end face.

[0031] The external colored portion is formed by dyeing the surface of the molded cylindrical body 22, and also by dyeing the surfaces of the molded support portion 33 and anti-slip portion . The external colored portion may be similar to that in the first and second embodiments.

[0032] [Examples 5 and 6] FIG. 7 shows a cup 50 of the fifth embodiment and a cup support 41 of the sixth embodiment.

[0033] The cup 50 includes a cup body molded into a cup shape from methacrylic resin, and an external colored portion formed by dyeing the surface of the molded cup body with a dye. The cup holder 41 includes a cup holder body formed into a cylindrical shape from vinyl chloride resin, and an external colored portion whose surface is dyed with a dye. The external colored portion may be similar to that in the first and second embodiments.

[0034] [Examples 7, 8, and 9] FIG. 8 shows (a) chopsticks 60 of Example 7, (b) spoon 70 of Example 8, and (c) fork 80 of Example 9.

[0035] The chopsticks 60 include a chopstick body molded into a chopstick shape from polycarbonate resin, and an external colored portion formed by dyeing the surface of the molded chopstick body with a dye. The spoon 70 includes a spoon body molded into a spoon shape from polycarbonate resin, and an external colored portion formed by dyeing the surface of the molded spoon body with a dye. The fork 80 includes a fork body molded into a fork shape from polycarbonate resin, and an external colored portion formed by dyeing the surface of the molded fork body with a dye. The external colored portion may be similar to that in the first and second embodiments.

[0036] In Examples 4 to 9, similar to Example 1, there is no need to change the color of the molding machine, and not only is it suitable for small-scale production, but the color does not fade easily and there is no change in thickness.

[0037] The present invention is not limited to the above-described embodiments, and can be embodied by making appropriate modifications within the scope of the invention. [Explanation of symbols]
