Description

  The present invention relates to a drinking cup.

Conventionally, in drinking cups, a heat-retaining cup has a double structure made of glass or metal and is welded in the vicinity of the opening. In recent years, there is a double layer made of plastic or paper and stacked near the opening. Furthermore, there is a combination of plastic products and metals.
However, joining and welding near the opening, and overlapping near the opening, for example, when putting a hot drink in the cup and making it into the mouth, it makes the mouth without feeling the heat and burns the lips etc. And from past experiences such as burns, it could be a horrible drink. In addition, the outer shape of the cup itself was a substantially cylindrical or inverted truncated cone, so it was difficult to hold and it was difficult to turn the wrist.

Patent Document 1 describes a mug in which the outer side with a handle portion is molded from a synthetic resin material, an appropriate space portion is formed inside, and the inner side of the container is formed of metal, but when a hot drink is put inside If the drink inside is not detected hot, it can be put in the mouth and burned in the lips and mouth.
Patent Document 2 describes a non-condensing container having a simple structure that does not cause condensation on the outer surface even when a low-heat liquid is poured, but does not consider the temperature felt on the lips.
Patent Publication No. 7-327803 Patent Publication No. 2005-88898

  While keeping the hot drink moderately warm and feeling the inside temperature with the lips before drinking, it prevents the lips and the like from being burned when drinking the hot drink. Also, when you drink cold things, put a lot of cold things in your mouth at once to prevent freezing on your teeth. Also, when drinking, elderly people are difficult to hold and may drop the cup. In addition, if the cup is not tilted greatly, the liquid inside the cup does not flow out, and if the head is not tilted back, it is difficult to drink the drink inside, and it is easy to spill from the side of the lips.

The easy-to-drink cup of the present invention is a double-structured drinking cup with improved heat retention,
A drinking mouth was provided near the opening of the cup, and the drinking mouth was formed in a single layer.

A depression was provided on the inner wall of the drinking mouth.

The area of the drinking mouth was 4 square centimeters or more.

A handle portion was provided on the outer shape of the cup in a direction substantially opposite to the drinking mouth portion.

The inner wall has a shape that gradually narrows from the opening along the back from the opening,
The tilt angle of the cup, which is necessary for all the drinks in the cup to flow out of the mouth,
The angle was 85 degrees or less with respect to the vertical.

The cup is made of ceramic, glass or metal, or paper or plastic,
Furthermore, it is an easy-to-drink cup characterized by a combination of these.

  The easy-to-drink cup of the present invention, for example, when hot drink is put and drunk, heats the lip to be drunk from the mouth by making the mouth opening near the opening non-double. Is transmitted. For this reason, it can be urged to say it little by little when it is hot. In addition, by having a double structure except for the vicinity of the opening, heat retention is maintained and heat is not easily transmitted to the hand and is easily held. As the heat retaining property, for example, when drinking tea or coffee, it is considered that the heat retaining property for a long time is not necessarily required. Therefore, a simple heat retaining cup can be obtained. In addition, the amount of disposable paper and plastic cups can be reduced.

The top view and sectional drawing of Example 1 of an easy-to-drink cup are shown. The top view and sectional drawing of Example 2 of a cup which are easy to drink are shown. The use condition of Example 2 of the cup which is easy to drink is shown. The top view of the state which grasped the cup of Example 2 of the cup which is easy to drink is shown. Sectional drawing of Example 3 of the cup which is easy to drink is shown. Sectional drawing of Example 4 of the cup which is easy to drink is shown.

FIG. 1 shows Example 1 of a cup that is easy to drink, (a) shows the outer shape of the cup 1, and (b) shows a cross-sectional view of the cup 1. The cup 1 is composed of an inner cup 2 and an outer cup 3, joined in the vicinity of the opening 5, and has a hollow portion 4 inside. A single drinking mouth 6 is formed in a part of the opening 5. The provided state is shown.
The cup 1 has an indentation 20 near the middle in the vertical direction, and the upper part of the cup 1 is hung on the finger turned by the indentation 20 when held by hand, making it difficult to drop the cup 1 from the hand. . In addition, the entire structure has a double structure, and the lower bulge portion 30 easily fits inside the palm of the hand and has a shape that is easy to hold. In addition, there is heat retention, for example, it is difficult to transmit heat to the hand that is held when a hot drink is put. In addition, the structure of the lower bulging part 30 and the hollow part 20 allows the hand to be gripped almost like a ball, so that the wrist can be moved freely and even the elderly with a hard wrist adjusts the angle of the hand by gripping. be able to.
As shown in FIG.1 (b), the drinking mouth part 6 provided in the opening part 5 does not become a double structure, but forms the single part. For this reason, when the cup 1 is tilted and touches the lips, heat is transmitted in the vicinity of the opening of the drinking mouth 6 and the lips know the heat before drinking. By these things, the amount of tilting is adjusted, and for example, instructions to keep in mind to drink little by little are transmitted to the brain. This prevents burns on the lips.
For example, the cup 1 is made of porcelain, the hollow portion 20 has a diameter of 50 mm to 80 mm, and the diameter of the bulge portion 30 is increased by 10 mm to 20 mm from the diameter of the hollow portion 20.
The drinking mouth 6 is 4 to 8 square centimeters from the opening 2 to the periphery, for example, semicircular.
In this way, for example, when it comes to hot drinks, even if you know the heat, you can keep warm, and the hands you hold are not hot, and it is easy to hold, so it becomes a cup easy to drink for the elderly and small children.
The bottom of the outer cup 3 is provided with an air hole 40 through which air is leaked so as not to be ruptured or destroyed due to expansion of air inside when heated in a microwave oven or the like. The air hole 40 is closed with a cap. The air hole may be closed with a putty or a putty. Further, when a metal such as a stainless steel is used, there is no need for an air hole.

FIG. 2 shows an easy-to-drink example 2 of the cup, and the inner wall surface of the cup 1a is narrowed toward the back with the opening 5 widened outwards. It has a structure that flows down, and can suppress (reduce) the amount that the drinker falls back.
An inclination line 7 is shown with a rising angle α of, for example, 85 degrees to 70 degrees with respect to the horizontal.
(In other words, the tilt angle of the cup required for all the drinks in the cup to flow out of the opening is 85 to 70 degrees with respect to the vertical.)
Further, a handle 8 is provided on the side of the opening that is substantially opposite to the drinking mouth.
FIG. 3 shows an example of use of a cup 2 which is easy to drink. By grasping the cup 1a with a hand and putting the finger under the handle 8 and holding it, the finger grasped with the key part 81 above the handle is raised. Stable gripping is possible by pressing in such a direction as not to slip.
For this reason, it is a cup that is easy to drink even for people who are hard to put into their hands, and elderly people who have little power.
In addition, by drinking with the drinking mouth 6a placed on the lips 10, the drinking mouth 6a spreads more laterally than the opening, and the drink flows from this range to the mouth. This makes it difficult to spill from the lips by suppressing spreading and flowing sideways.
In addition, the drinking mouth has a recessed portion recessed inside, and a drink reservoir 6aa is provided in this portion, where the drink is once retained, so that it does not flow into the mouth at once, but is temporarily accumulated in the beverage reservoir 6aa. From the drink reservoir 6aa, it is possible to taste the drink little by little, for example, to lick it. Effective for elderly people who are thirsty and want to damp their mouth.
FIG. 4 shows a usage example of the embodiment 2 of the easy-to-drink cup, and shows a view from the top of the state where the cup 1a is grasped by hand and a finger is put under the handle.
A mode that the handle | steering-wheel 8 is provided in the side substantially opposite to the drinking mouth 6a with respect to the opening part 5 is shown.
Hereinafter, the points with the same description will be omitted.

FIG. 5 shows a cross-sectional view of Example 3 of the easy-to-drink cup, and the cup 1b shows a main body made of, for example, stainless steel.
The cup 1b shows what the outer cup 3 and the inner cup 2 were shape | molded, each was welded, and the surface was grind | polished.
By making it stainless steel, it is possible to make a cup that is versatile and hard to break, such as drinking beer. At that time, a curl or an edge may be provided near the opening 5.
Further, the handle 8 can be held more stably by providing the finger holes 8aa and passing the fingers through the finger holes.

As another example, a cup made of glass and welded after molding the outer side and the inner side, for example, can be made suitable for drinking wine or beer while keeping it cold.
Further, it may be made of plastic.

FIG. 6 shows a cup 1c of Example 4 which is an easy-to-drink cup, and shows the cup 12 formed by covering the outer cup 3c with the inner cup 2c. For example, the inner cup 2c is formed of stainless steel, and the outer cup 3c is insert-molded with plastic. At that time, a protrusion or a hole may be provided on the joint surface between the cup inner side 2c and the cup outer side 3c to enhance the joint. Further, instead of insert molding with plastic resin, it may be molded separately and then fitted or bonded.
Further, a combination of these including paper, plastic, and metal may be used. The inner cup 2c and the outer cup 3c may be fitted or assembled by bonding with an adhesive or the like. Moreover, although not shown in figure, it is good also as a structure which forms the base, for example, the base which cross-assembled the thin plate in the state which stood inside the outer side cup 3c, and mounts the bottom of the inner side cup 2c on it.
