BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-insulating cup with a leak-preventing function that allows the user to drink an internal beverage by opening the spout even when the lid is covered.

[0002]

2. Description of the Related Art There are various types of beverage containers which can be kept warm, such as a small pot which is convenient to carry and a so-called mug cup having a double cylindrical shape. A regular small pot has a tightly-sealed inner lid at the upper opening of the container body, loosens the inner lid after removing the outer lid, and allows the beverage to flow out, and after drinking, tighten the inner lid and seal it tightly, An outer lid is placed over it.

[0003]

In such a conventional pot, it is troublesome to remove the lid because of the double lid structure of the inner lid and the outer lid, but once the beverage is once transferred from the container to the outer lid or the like. It took a lot of time to change, so it was unsuitable for drinking directly from a container like a glass.

[0004] Mug cups with a lid have a certain degree of heat retention, but this also has the same disadvantage in that it requires the trouble of removing the lid and then drinking it. There is an inconvenience. Further, the above-mentioned containers with a lid have a problem that if the lid is not tightly tightened, the beverage is spilled when the container is accidentally turned over, which may cause an unexpected situation.

[0005] The present invention has been made in view of such a conventional situation, the purpose is to be able to drink without removing the lid because the spout provided on the top of the lid can be opened with one touch. Another object of the present invention is to provide a heat-insulating cup in which the drinking mouth is automatically closed when drinking is completed, and the leakage of the beverage is prevented even if the container is turned over.

[0006]

In order to achieve the above object, according to the present invention, the container body comprises an inner cylinder and an outer cylinder made of a synthetic resin, and a heat insulating material is inserted into a space between the inner cylinder and the outer cylinder. The upper end of the inner cylinder is welded to the upper end of the outer cylinder located in the inverted portion of the upper end. Then, the upper opening is formed in the synthetic resin lid having a larger diameter at the lower part than the upper part. It has a guide piece which stops engaging with a projecting piece formed on the side wall. Furthermore, a drinking spout is provided on the top surface of the lid, and when a push button attached to the upper side surface of the lid is pressed on the back surface of the drinking spout, a base pivotally supported on the top surface by a pressing element connected to the push button is used as a fulcrum. The opening and closing piece that moves away from the spout is elastically exposed. In the case where the outer cylinder is transparent, images and advertisements can be seen through by winding decorative paper around the heat insulating material.

[0007]

[Function] When the push button on the side of the lid is pressed with a finger, the opening / closing piece which is in close contact with the drinking spout is lowered by the pressing element located inside the lid with the base as a fulcrum, so that the drinking spout is opened.
The beverage flows out of the spout, so you can drink it without removing the lid.

Since the push button automatically retracts when the finger is released, the opening / closing piece returns by its own spring action and closes the drinking spout.
Therefore, the beverage is in a form in which all outlets are closed, and does not leak even if the container is turned over.

When the lid is turned to one side, the lid is disengaged from the main body and can be removed. Therefore, the beverage is poured from the opened upper mouth. By turning and fixing, the whole container is sealed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a container body comprising an inner cylinder 2 made of synthetic resin and a transparent outer cylinder 3 made of synthetic resin. A space 4 exists between the inner cylinder 2 and the outer cylinder 3, and a vinyl is provided in the space. A heat insulating material 5 such as foam or urethane is charged. The heat insulating material 5 is arranged so as to be wound around the inner cylinder 2, and further, decorative paper 6 is wound around the heat insulating material 5. By printing images 7 such as various color patterns and advertisement phrases on the decorative paper 6, they can be viewed from the outside. If the outer cylinder 3 is not made transparent, an image is printed directly on the surface of the outer cylinder, so that naturally no decorative paper is required.

The upper opening 8 of the inner cylinder 2 is formed to be bent outward in an inverted manner, and the upper end of the outer cylinder 3 is positioned inside the side wall 9. Welding is performed using a welder, and a plurality of horizontally long protruding pieces 10 are formed at equal intervals on the lower portion of the outer peripheral surface of the side wall 9.

Numeral 11 denotes a synthetic resin lid which covers the main body 1.
The lower part is larger than the upper part in the shape of a two-tiered upper and lower part, and a concave part 12 is formed inside the lower part, in which the upper opening 8 of the main body is fitted. Guide piece 1 that engages with
4 are provided in the same number as the protruding pieces.

The guide piece 14 has a horizontal portion 14a and a vertical portion 14b.
When the lid is turned to the right with the lid over the upper opening, the protruding piece 10 is tightly engaged with the upper side of the horizontal
Stop at point b. The lower part of the lid 11 exerts an elastic function peculiar to the synthetic resin and fits tightly with the upper opening 8 of the main body. Does not leak out. In order to remove the lid 11, it is necessary to once rotate in the opposite direction, that is, to the left, to disengage the projection 10 and the guide piece 14.

The top surface 15 of the lid 11 is formed to be inclined, and an elliptical drinking opening 16 is provided at the lower part. Beverage is provided in the lower part, making it easier to drink and less likely to spill. The opening / closing piece 17 made of synthetic resin is elastically exposed to the back side of the mouthpiece 16, and the mouthpiece 16 is closed or opened when the opening / closing piece 17 comes and goes.

The opening / closing piece 17 is a kite-shaped support leg 1 formed on the left and right.
8 is pivoted to the back of the top surface 15 with a pin P,
The contact point 6 has a slightly larger elliptical shape so as to fit into the spout, and the upper surface intervenes in the spout. A slope 19 is provided at the center of the rear side, and when the slope is pushed, the opening / closing piece descends.

Reference numeral 20 denotes a push button attached to the upper side surface of the lid opposite to the drinking port 16, and the push button is integrally connected to a presser 21 inside the lid and in contact with the slope portion 19 of the opening / closing piece. When the push button is pressed, the pusher 21 is interlocked and the end of the pusher 21 is pressed against the slope, so that the opening / closing piece 17 descends with the pin P of the supporting leg 18 as a fulcrum and separates from the drinking spout 16. Since the end of a spring piece 22 integrally formed with the slope portion 19 is attached to the presser 21, the spring piece 22 contracts when the push button 20 is pressed, but expands when the finger is released from the push button. The pusher 21 is retracted together with the push button.

The opening / closing piece and the push button are not limited to the above-mentioned shapes. For example, as shown in FIG. Acts as a cam so that the opening / closing piece 17 can be opened. Also in this case, when the finger is released from the push button, the presser 21 automatically returns to its original shape, so that the opening / closing piece 17 also returns to its original position by its own spring action and closes the spout. Therefore, in such a structure, since the position of the pressing element is orthogonal to the opening / closing piece, it is convenient for a container in which the handle 30 is provided on the main body 1 as shown in FIG. In other words, when the handle 30 and the push button 20 are provided in the same direction, the push button 20 can be pressed with the thumb when the handle 30 is grasped, and the spout 1 is easily swallowed.
6 can be located on the near side.

The main body and the lid are not restricted to the shapes shown in the figure, but if they are formed in a rectangular shape, for example, it is convenient because they are difficult to roll even in an unstable place such as in a car.

The present invention has the following specific effects. (1) When the push button is pressed, the spout opens, so you can drink the internal beverage without having to remove the lid, and when you release your finger from the push button, the spout closes automatically, making operation extremely easy. Done. (2) Since the opening and closing of the drinking spout can be performed instantaneously, it is possible to handle the car with ease without spilling, for example, while driving a car. (3) Since the main body is composed of an inner cylinder and an outer cylinder, and a heat insulating material is inserted into the space, the beverage is kept warm and hard to cool. (4) The main body and the lid maintain a tight engagement state unless they rotate in a certain direction, and the drinking mouth does not open unless the push button is pressed, so that there is no danger of the beverage leaking even if the main body is turned over. . (5) Since the opening / closing piece and the pressing element can be crossed,
If the handle is attached to the main body and the push button is provided in the same direction as the handle, the drinking spout can be located on the near side for easy drinking, and there is an advantage that the push button can be easily operated. (6) When the outer cylinder is made transparent, the image can be freely displayed on the decorative paper, and the advertisement text and the company name can be made completely different just by changing the decorative paper. (7) Since the inner lid is not provided, the structure is simple and the main body and lid are made of synthetic resin, so that the product can be provided at low cost. It is treated with no interest.
