Description

[Detailed Description of the Invention] The present invention relates to the structure of a magic bottle stopper.

Conventional magic bottle stoppers are of the type in which a female thread is carved into the shoulder body provided at the mouth of the bottle, and a male thread is carved into the outer periphery of the stopper, which is screwed onto the female thread. , which are sold in large numbers as having a highly safe structure. However, with this type of system, when pouring water, you have to rotate the tap to loosen it and raise it to a certain level before you can pour water, and after pouring water, you have to turn the tap again to tighten it, which is a hassle. . or,
It is also known that a valve is attached to the stopper, and when the magic bottle is tilted, the valve opens and water can be poured, but all of these types of devices have a complicated structure and a large number of parts. It was easy to break down and expensive.

The object of the present invention is to provide a magic bottle stopper which can be filled with water by simply tilting the magic bottle, and which has an extremely simple structure and is inexpensive.

The present invention will be explained below based on the drawings.
The figure shows a charm bottle 2 with a stopper 1 of the present invention. The magic bottle 2 has an inner bottle 4 housed in a body 3, and a shoulder member 6 having a water inlet 5 is provided at the mouth of the bottle.
A female thread 7 is formed on the inner periphery.

The stopper 1 has a structure as shown in FIG.
The lower part of the side wall 8 forms a hollow cylindrical side wall 8, and the lower part of the side wall 8 has a male screw 9 protruding from its outer periphery, and the upper end thereof protrudes outward to provide a flange 10 over the entire circumference. A knob 11 is provided protruding from the upper part of the flange 10. and tsuba part 1
A plurality of water injection holes 12 are opened on the entire circumference of the side wall 8 directly under the side wall 8 .

When this stopper 1 is screwed into the female thread 7 of the water inlet 5 of the magic bottle 2, the screwing is completed because the male thread 9 of the stopper 1 protrudes only from the lower part of the side wall 8. When the male thread 9 passes through the female thread 7, the stopper 1 falls into the water inlet 5, and the flange 10 of the stopper 1 comes into contact with the upper surface of the shoulder member 6 around the water inlet 5 and is supported. This state is shown in FIG. In this state, the plug 1 can freely swing up and down with respect to the shoulder member 6, but cannot be removed upward.

Next, when the magic bottle 2 is tilted, the outflow pressure of the liquid inside pushes the stopper 1 upward as shown in Fig. 3, and the liquid inside flows out from the water injection hole 12 as shown by the arrow. It can be released. At this time, since the female thread 7 and the male thread 9 are engaged, the plug 1 will not fall out. Furthermore, if the magic bottle is placed upright after the water has been poured, the stopper 1 will fall down again due to its own weight, returning to the state shown in Figure 1.

Since the present invention has the above-mentioned structure, there is no need to rotate the stopper when pouring water, and water can be easily poured by simply tilting the magic bottle.Moreover, the structure is extremely simple, and it is made of plastic. It can also be produced in one step using the injection molding method, and it is inexpensive and does not break down. Also water injection hole 1
Since a plurality of openings 2 are provided along the entire circumference of the side wall of the stopper 1, the stopper 1 has no directionality, and water can be injected from any position. There is no need to check.

Furthermore, as shown in the drawing, the magic bottle is provided with a lid 13 that can be opened and closed, and the back surface of the lid 13 and the top surface of the stopper are very close to each other when the lid is closed, as shown in FIG. Even in the event of a fall, the stopper 1 will not be pushed up and the liquid content will not leak out, making it safe. Also, when removing stopper 1, remove stopper 1.
It can be easily removed by pulling it up and rotating it.

In the present invention, when the magic bottle 2 is in an upright state, the upper surface circumference of the bottle opening is covered by the lower surface of the flange 10 of the stopper 1, so the heat retention effect is sufficient. However, in order to further increase the heat retention effect, If the bottom of the stopper 1 is covered with a net-like cover, a higher heat retention effect can be obtained. The heat retention effect can also be enhanced by fitting a heat insulating material such as styrofoam or cork inside the knob 11.
