JPH07148058A - Liquid vessel such as sake cup or bowl, and its manufacture - Google Patents

Abstract

PURPOSE:To provide a liquid vessel such as a sake (Japanese rice wine) cup or a bowl wherein a pattern on the bottom of the liquid vessel is indistinct before a liquid is poured, but the pattern is clearly appeared by pouring the liquid, so that the pattern can call the interest to the appearance. CONSTITUTION:A transparent semi-spherical lens 3 is provided on the bottom surface of a vessel body 1 whose upper surface is opened, and a pattern 4 such as picture or print is formed on the opposite surface of the lens 3 which can be seen through the lens 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when pouring a liquid such as water or liquor into a liquid container such as a glass, a bite beer glass, a chisel, a bowl, etc., which has a large open upper surface, is used for painting or printing from the liquid surface. The present invention relates to a liquid container such as a cup and a bowl in which the pattern is unclear even though the pattern can be seen and when the liquid is not poured, and a manufacturing method thereof.

[0002]

2. Description of the Related Art As a conventional liquid container into which a liquid is poured, the upper surface of a cup, a pile, a bowl, etc. is widely opened.
Often made of opaque material such as carved wood, plastic, ceramics, etc.In the case of wood and plastic, the inner surface is colored with lacquer, and sometimes it includes bite beer glass. It may be made of transparent or translucent glass.

[0003]

The inner surface of these liquid containers to which the liquid is poured is the color of the cloth such as white in the case of ceramics, and the pattern, characters, etc., including the case of coloring such as lacquer. A pattern is rarely drawn, and a non-pattern is common. Even if a pattern is drawn or a liquid is poured, the pattern does not change, which is not very interesting.

The present invention is intended to solve the above-mentioned problems, and the purpose thereof is that the pattern on the bottom of the liquid container is unknown before the liquid is poured, but the pattern is obtained by pouring the liquid. The purpose is to provide a liquid container, such as a cup or bowl, that can be made to stand out clearly and bring out the interest in the rise of the design.

Further, according to the present invention, since the pedestal portion is heated to such a degree that it can be processed, and the excess glass becomes a lens shape by being sandwiched by the split gapper, it is easy to manufacture and the cost can be reduced. It is intended to provide a method of manufacturing a liquid container such as a bowl.

[0006]

The liquid container such as a cup and bowl according to the present invention is intended to achieve the above-mentioned object. The means is a transparent hemisphere on the bottom surface of the container body whose upper surface is open. It is characterized in that a lens having a shape is provided and a pattern such as a painting or a print is formed on the opposite surface of the lens which can be seen through the lens.

Further, a step of manufacturing a liquid container such as a cup and a bowl having a pedestal, a step of heating the pedestal of the liquid container to an extent that can be processed, and a pedestal with a split gapper having a volume smaller than the volume of the pedestal. It is composed of a step of forming a predetermined pedestal shape with sandwiching it and forming a lens by raising excess glass on the inner surface of the container, and a step of forming a pattern, a pattern by cutting, sand plast, painting etc. on the bottom surface of the pedestal. It is a manufacturing method.

[0008]

Since the liquid container such as the cup and bowl of the present invention is constructed as described above, the lens provided on the bottom surface of the container body
Paintings, prints, etc. formed on the opposite side of the lens can be seen through, but since this lens is hemispherical and the magnification is very large, only a part of the design such as paintings, prints, etc. can be seen through. Become.

Therefore, although it is not clear what the whole design depicts, when pouring hot water, liquor, etc. into the container body,
Since the lens and these liquids come into contact with each other, the refractive index in the case of interposing a liquid between the glass and the air is lower than the refractive index of the light rays of the glass and the air, so that the enlargement ratio becomes smaller. Through the lens, you can see the whole picture and design.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment in which the present invention has been fully implemented will be described below with reference to FIGS. In this embodiment, as shown in FIG. 2, a bowl-shaped container body 1 and a pedestal 2 whose upper surfaces are largely opened are integrally molded by transparent glass.

The pedestal 2 of the cup is preferably cylindrical, and the bottom surface of the container body 1 which is connected to the pedestal 2 is preferably formed flat. The cup is heated to such an extent that the pedestal 2 can be processed in preparation for the next step. deep.

In the next step, a split gapper A having a truncated conical tip sandwiching portion, as shown in a plan view of FIG. 3 and a side view of FIG. 4, is used. In this step, the side of the cup base 2 close to the container body 1 is sandwiched by the conical small-diameter side of the sandwiching portion of the split gapper A, and the entire cup is rotated in the split gapper part to finish the base 2 into a conical shape. .

Then, on the bottom surface of the container body 1, excess glass due to the conical shape of the pedestal 2 rises to form the lens 3 of FIG. 1 which is almost hemispherical. A pattern or pattern 4 is applied to the bottom surface of the pedestal 2 thus molded by cutting, sand plasting, painting, or the like.

The pattern of this painting or printing has a size that is transparent through the lens 3 due to the decrease in the refractive index caused by the contact between the glass and the liquid when pouring a liquid such as hot water or liquor into the container body 1. To do. When the liquid in the container main body 1 is discharged, the air and the glass come into direct contact with each other, so that the enlargement ratio becomes large, and only a part of the design is extremely magnified and seen through to see what the design is. It cannot be confirmed.

Although the above-mentioned embodiments are all carried out in a cup, the same action and effect can be obtained by carrying out in a bite beer glass, a guinea pig, a soup bowl or the like.

[0016]

As described above, according to the present invention, by the lens formed on the bottom surface of the container body, only a part of the painting or print provided on the opposite surface seen through the lens is extremely enlarged, and I cannot see through and cannot see the whole design.

Therefore, although it is not known what the design is, when the liquid is poured into the container body, the refractive index of the lens is lowered by this liquid, the magnification is reduced, and the entire design can be seen. Then, the rise of painting and printing by pouring this liquid aroused interest,
It can contribute to the sales increase of liquid containers such as cups, bite beer glasses, guinea pigs, and soup bowls.

Further, in forming the lens portion, since the pedestal portion is sandwiched by the split gappers and the surplus glass constitutes the lens portion, it is not necessary to attach the lens afterwards to manufacture the lens. It has an effect that it is simple and the cost can be reduced.
