A glass inner wall is inserted inside of the wooden outer wall and the upper edge or the vicinity of the upper edge of the wooden outer wall is sealed with the glass inner wall.SELECTED DRAWING: Figure 7

Description

  This article relates to a drinking cup having a double wall for the purpose of keeping warm and keeping cold, which is widely used in glass, metal, resin, and ceramics. The present invention relates to a drinking cup in which glass is combined as an inner wall to double the wall.

  For the purpose of preventing burns, such as using a paper coffee cup as a resin cover on the outside, a separate cup and its cover are nested and set regardless of screw tightening. The type of drinking cups that can be easily detached is not sealed by using a sealing material at the joint between the cup and the cover, and the effect of heat insulation and cooling is greatly reduced due to the large amount of air going in and out. The purpose is different, such as liquid invasion and soiling but easy washing. Other than paper cups, separate cups and their covers are in a nested set.Drinking cups for the purpose of preventing burns are not widespread. Market size is very different. Therefore, these types of cups are excluded.

  Drinking cups having a double wall for the purpose of keeping warm and cold are often made of glass, metal, resin, or ceramic, but drinking cups having a double wall made of wood are not found in the market. In addition, there is a drinking cup (see, for example, Patent Document 1) having a double wall composed of a different material such as a resin outer wall and a metal inner wall, and different materials such as a wooden outer wall and a glass inner wall. A drinking cup comprising a double wall can be easily devised.

  In the case of a drinking cup that consists of different materials, such as wood and glass, the drinking glass is different from the same material such as glass or metal in order to prevent liquid intrusion and air ingress and egress at the seams of different materials. Can not be melted and welded. For this reason, it is necessary to seal the joints of different materials using a seal material made of a material different from wood or glass, such as a gasket, packing, or adhesive. Alternatively, by forming and tightening screw grooves on the outer wall of the wood and the inner wall of the glass, sealing can be performed by bringing different materials into close contact with each other, thereby achieving the purpose of heat insulation and cold insulation. Further, in the case of tightening by screw machining, sealing can also be performed using a sealant simultaneously with the screw machining.

  For the purpose of heat insulation and cold insulation, which is widely used in glass and metal, etc., for wood used for furniture and panels of luxury cars for the sensory reasons such as the beauty of the grain and healing It is technically possible to produce as a drinking cup with a double wall. However, when a double wall is made of wood, there are many problems such as high manufacturing costs for hollowing out the wood and difficulty in mass production. Therefore, it is possible to easily devise a drinking cup having a double wall made of different materials, using the characteristics of wood, while the outer wall remains wooden and the inner wall is made of glass. However, in actual use and manufacturing, there are several problems in the sealing technology between different materials and the characteristics of the material, such as wood. is there.

  A drinking cup having a double wall such as glass or metal is composed of an outer wall and an inner wall, and usually the outer wall and the inner wall are in contact with each other at or near the upper end of the cup. When actually manufacturing a drinking cup having a double wall with the outer wall made of wood and the inner wall made of glass, for example, as in Non-Patent Documents 1, 2, 3, and 4, the upper end of the cup or the vicinity of the upper end is It is necessary to perform sealing by using a sealing material or screw processing so that liquids and air do not enter and exit from this seam because they are in contact with different materials. The upper end portion of the cup or the vicinity of the upper end portion is a portion directly touched by the human lips. Therefore, the seam of different materials is required to be a surface free from unevenness or an adhesive due to an adhesive or the like so as not to deteriorate the touch. In addition, if there are irregularities in the joints of different materials, dirt is likely to accumulate in the recessed groove portions and it becomes unsanitary, so it is required that there are no irregularities. However, in order to finish a seam between different materials that cannot be melted and welded, such as glass or metal, in manufacturing, it requires high sealing technology and manufacturing cost, and mass production becomes difficult.

  In the same way as the cypress and cypress, I often make high-quality cocoons, etc., but in the same way, I seek the beauty of the wood grain, the outer wall using soft wood is wooden, the inner wall is made of glass If you make a drinking cup with a double wall sealed at or near the top of the cup, it will easily dent if a young child bites the cup rim or an adult bites and carries the cup. Since the tooth profile is attached, there are disadvantages that the aesthetic appearance is impaired and the life is shortened. Even if you want to use even softer, beautifully grained wigs or economically cheap cedar trees, for this reason, there are challenges that you cannot use for drinking cups.

  For example, wooden bowls with lacquering or urethane coatings will shorten the life of lacquer and paint painted on the surface of the wood as they are used. Unlike those with no material, it is not recommended to rub strongly or wash with a strong detergent. In particular, high-quality paints such as beeswax and strawberries, and those using unpainted wood such as cypress baths are also vulnerable to washing. Therefore, when manufacturing a drinking cup that has a double wall that is made of glass with an outer wall made of glass and an inner wall made of glass and bonded at or near the upper end of the cup, the double wall is made of glass, metal, or ceramics. It is necessary to handle it more carefully than the cups that make up. In spite of this, the part that is touched by human lips is the most dirty part with sticky tea astringents and lipsticks, oil contained in cooking on the lips, etc. Inconveniences such as being unable to wash by rubbing more strongly, such as made of metal or ceramics.

  The present invention employs the following configuration in order to solve the above problems. Figure 1 shows a white ceramic drinking cup that has been measured with a ruler to determine that the soiling area is more than 1 centimeter from the top edge of the cup as a result of an experiment to determine the soiling area without washing with detergent for about 3 months. It is. Even for people with large lips, it was assumed that the part where many people's lips hit the cup is more than 1 centimeter from the upper end of the cup and is about 2 centimeters or less depending on the person. The part where the lip hits is the part where the unevenness is felt, it is easy to get dirty, or the tree is recessed when chewed, as described in the problem to be solved by the invention. Therefore, when commercializing a drinking cup having a double wall composed of a wooden outer wall and a glass inner wall, the outer wall is not simply made of wood up to the upper end or near the upper end, but the upper end of the cup. The part of the lip that touches the human lips, from about 2 cm down to about 2 centimeters, is made of single-walled glass connected from the inner wall so that the lips do not hit the wooden outer wall.

  Even though it is a drinking cup with a double wall with the outer wall made of wood and the inner wall made of glass, the part where the human lips come in contact can be made into a surface that is free from unevenness due to joints between different materials and the roughness caused by adhesives, etc. Improves the touch on the surface and makes it difficult for dirt to accumulate in the concave and convex grooves.

  Even though it is a drinking cup having a double wall with the outer wall made of wood and the inner wall made of glass, even if the edge of the cup is chewed, the tooth shape is attached and the aesthetic appearance is not impaired and the life is extended.

  Although it is a drinking cup with a double wall with the outer wall made of wood and the inner wall made of glass, you can use soft types of trees, so you can increase the number of beautiful trees that can be used, or use economically cheap trees be able to.

  Although it is a drinking cup with a double wall with the outer wall made of wood and the inner wall made of glass, the part where the human lips hit is made of glass used in chemical experiments, so use strong detergent or rub it hard. It is easy to remove stains such as tea astringents, lipsticks and oils, and high-quality painted trees such as beeswax and strawberries, and unpainted trees such as cypress baths can be used on the outer wall, and the type of cup design It can be greatly increased.

  Although it is a drinking cup with a double wall with the outer wall made of wood and the inner wall made of glass, when you drink whiskey and other Western liquors, the touch when touched by the mouth has the same reminiscent as a bowl used in rice cake or sake. There is little discomfort because it is made of glass, not wooden. At the same time, you can also enjoy the beautiful tree appearance reminiscent of a whiskey barrel.

  The portion of the cup that hits the lips from the upper end of the cup to around 2 centimeters is not a double wall and is a single wall of glass, but when you actually pour a drink into the cup, you can spill it. In many cases, the beverage is not put up to the top or near the top of the cup, and even if it is put up to the single wall part, the time that the drink is put up to the single wall part is the drink If you look at the ratio of the total time it takes for a person to drink up, it is often short, so even if the upper end or near the upper end is not a double wall, the decrease in the effect of heat insulation and cold insulation is a big difference in practical use. It is hard to produce.

  The effects of the above device can be realized with low manufacturing technology and low manufacturing costs, and mass production can be facilitated.

As a result of an experiment to determine the dirty area without washing with detergent for about 3 months, it was a white ceramic drinking cup that was measured with a ruler that the dirty area was 1 cm or more from the top of the cup.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. Figure 1 shows a white ceramic cup that has been tested for about 3 months to determine the extent of soiling without washing with detergent. The experimental result shows that the area where the lips touch and become soiled with tea astringents is 1 cm from the top of the cup. It is shown that there is more. The range where the actual lips touch the cup is larger than the range where it gets dirty, and if you become a large person such as a Westerner, the lips will touch the cup more. Therefore, even for people with large lips, the portion where many people's lips hit the cup was assumed to be about 2 centimeters below from the upper end of the cup. The person's lips 3 represent the situation where the person's lips are in contact with the cup when drinking with a cup by an imaginary line by a two-dot chain line. 2, 3 and 4 are drinking cups having a double wall sealed at or near the top of the cup, representing a situation where a person tilts the cup and drinks. FIG. 2 shows an example in which sealing is performed at the upper end of the cup using a sealing material made of an adhesive having almost no thickness. FIG. 3 shows an example in which sealing is performed in the vicinity of the upper end of the cup using a sealing material made of an adhesive having almost no thickness. FIG. 4 shows an example of sealing in the vicinity of the upper end of the cup by processing and tightening thread grooves on the outer wall of the wood and the inner wall of the glass. The cases of the cups of FIGS. 2, 3 and 4 are sealed at or near the upper end of the cup, so that the human lips 3 are in contact with the wooden outer wall 1, and the problem to be solved by the invention The problem described in the above will occur.

  In the present invention, in order to prevent the lips from coming into contact with the wooden outer wall 1 when the wooden inner wall 2 is put inside the wooden outer wall 1 in the process of manufacturing the wooden outer wall 1 and the glass inner wall 2, 2 is designed to be longer than the upper end 1a of the wooden outer wall so that the width of the lip of the person hits is long. And the glass inner wall 2 is put inside the wooden outer wall 1, and it seals with the glass inner wall 2 by the upper end part 1a of a wooden outer wall.

  5, 6, and 7 are cups in which the glass inner wall 2 is placed above the upper end 1 a of the wooden outer wall so that the human lips do not hit the wooden outer wall 1, and the width that the human lips hit is longer, The joint between wood and glass is an example in which sealing is performed at the upper end portion 1a of the wooden outer wall using a sealant made of an adhesive having almost no thickness.

  FIG. 8 is a cup in which the glass inner wall 2 is placed above the upper end 1a of the wooden outer wall so that the human lips do not hit the wooden outer wall 1 and the width of the human lips hit is increased.
