Drinking cups

Abstract

To provide a drinking cup which is easy to hold, easy to drink from, and does not easily tip over. [Solution] The drinking cup is made of a short cylinder with the same diameter as large and small truncated cones at the upper part, and is drum-shaped with an inverted truncated cone at the upper part and a truncated cone at the lower part, with the two parts joined at a gentle angle.

Description

[Technical field]

[0001] The present invention is a design that adapts the shape of a drinking cup to the current lifestyle.

[0002] Generally, cups for holding hot drinks such as coffee, or cold drinks, are shaped like an inverted truncated cone, or a stable cylindrical or truncated cone. However, inverted truncated cone cups tend to tip over when the top is touched, and cylindrical and truncated cone cups have the disadvantage that they cannot be used to drink from unless they have a handle. Summary of the Invention [Problem to be solved by the invention]

[0003] When you go to a takeaway or cafe in town and order coffee, it is served in an inverted cone-shaped paper cup or a cylindrical ceramic cup, but sometimes you knock it over when you try to pick it up, or when you place it next to your computer and you are working while drinking from it, the cup can tip over when you try to pick it up or just by touching it, causing the coffee inside to spill onto the table or onto your PC, interrupting your work or, in the worst case, making your PC unusable. These are real experiences. At that time, we thought that if there was a cup that would not tip over just by touching it, it would be possible to place it next to a PC while working with peace of mind, and so we came up with the drum-shaped drinking cup. [Means for solving the problem]

[0004] This invention is a drinking cup that is shaped like a drum by stacking a small inverted cone at the top, a large cone at the bottom, and a low cylinder in the middle, making it difficult to tip over, easy to hold, and stylish.

[0005] This device is drum-shaped, but by making the angle between the generatrix of the truncated cone and the perpendicular line constant and by having a cylinder, it is stable and easy to hold, allowing beverages to be drunk smoothly, and is unlikely to tip over even if touched when placed down. Effect of the Invention

[0006] This cup is suitable for modern lifestyles and can be placed next to you while reading a book or using a PC. The material can be resin-coated, double-walled stainless steel, glass, etc. Ceramic cups can be made with handles to improve heat transfer, allowing you to enjoy a variety of textures.

[0008] When the drum-shaped cup of this invention is disassembled, it becomes an inverted truncated cone-shaped upper part 6 with an open top surface of a diameter that makes it easy to drink from, a cylindrical middle part 7 with a low central part that forms a band with the same diameter as the diameter of the bottom of the inverted truncated cone upper part 6, and a truncated cone-shaped lower part 8 with a bottom 5, all joined together as one piece.

[0009] The generatrix from the bottom of the upper part 6 of the inverted cone at the top to the top surface part that becomes the drinking spout forms an angle of approximately 7.5 degrees.

[0010] The angle of the generatrix from top to bottom of the lower truncated cone 8 is also approximately 11 degrees. The diameter of the bottom is approximately 1 cm larger than the diameter of the upper surface of the upper part 6 of the inverted truncated cone.

[0011] The height of the cylindrical middle part 7 is 5 to 10 mm, which is easy to hold and provides a sense of stability when holding the cup. The diameter of the top surface of the upper part of the inverted truncated cone shape 9 is approximately 1.5 cm larger than the diameter of the middle part 7.

[0012] The ratio of the height of the top to the height of the bottom is 1:55 mm to 1:13, the ratio of the diameters is 1:77 mm to 1:13, and the diameter of the base is 1:0.8. These numbers were obtained by actually creating the bottle several times using a 3D printer and checking its comfort when drinking and how unlikely it was to tip over.

[0013] The volume of the cup was determined by measuring how much drink a number of cups contained, and this drum-shaped figure was derived from the figures.

[0014] The corners of the inside bottom of the cup are rounded to make it easier to wash.

[0015] By creating an inner bottom surface that is open about 1.5 mm from the bottom surface of the bottom part 5, the part directly placed on the food can be prevented from becoming hot.

[0016] The cup should be made of resin so that it can hold both hot and cold drinks, but stainless steel, glass, or ceramic are also acceptable.

[0017] If the material is ceramic, it will easily transmit heat, so a handle 14 is attached.

[0018] While a cylinder is not particularly interesting in terms of design, a drum-shaped drinking cup is easy to grab wherever you place it, and its stylish design will attract attention if placed in a cafe. [Explanation of symbols]
