Description

[Detailed description of the invention] (a) Field of the invention The present invention relates to a magic bottle stopper that allows liquid to be poured by lifting and tilting the main body of the magic bottle.

(b) Conventional technology and its problems Conventionally, the stopper used for this kind of magic bottle is
It is removably screwed onto the shoulder body of the magic bottle body, and by rotating this stopper to the open position, the sealing surface between the stopper and the shoulder body is separated, and by tilting the magic bottle body, the stopper can be opened. The liquid is injected through the gap between the shoulder and the body.

However, in this case, the main body of the magic bottle must be tilted after the cap is rotated to the open position, making it difficult to open and close the cap and inject liquid at the same time with one hand, making the operation cumbersome. Ta.

Therefore, as described in Japanese Utility Model Application Publication No. 57-196435, a liquid path is formed inside the stopper, and the valve element that opens and closes this liquid path is movable up and down and always urged upward by a spring. At the same time, a switch that moves forward and backward in the front and back direction is installed on the top of the stopper.
It is known that the inclined surface of the switch is brought into sliding contact with the upper end of the valve body, thereby converting the forward and backward movement of the switch into the vertical movement of the valve body, so that the valve body opens and closes the liquid passage.

In this case, by pressing the switch with the thumb of the hand holding the handle, it is possible to open and close the stopper and inject liquid at the same time with one hand. However, this not only complicates the internal structure of the stopper, but also requires the thumb to be pushed forward when opening and closing the stopper, which causes a forward rotational moment to act on the magic bottle body through the stopper. , there is a problem that the liquid injection port is wobbly and the streamlines are disturbed. Moreover, as the switch is pressed, the distance between the handle and the switch becomes longer, which requires the thumb to be fully extended, making it difficult for people with small hands to operate the switch.

(c) Purpose of the invention The present invention was developed in view of the drawbacks of the prior art.The purpose of this invention is to enable opening and closing of the stopper and injection of liquid at the same time with one hand, as well as to have a simple structure and a method for injection of liquid. To provide a cap for a magic bottle that does not have a wobbling opening, can be easily operated even by a person with small hands, and is resistant to leaking even if it falls over.

(d) Structure of the device In order to achieve the above object, the present invention is a magic bottle that is attached to the shoulder body of the magic bottle body, in which liquid is poured by holding the handle provided at the rear of the magic bottle body and tilting it. a valve body that is attached to the inside of the plug body so as to be able to swing vertically, and has a valve part at one end that opens and closes the sprue of the shoulder body; and an operating member rotatably mounted around a shaft, the operating member is provided with an involute curved guide groove or guide hole, and the other end of the valve body slides in this guide groove or guide hole. A stopper for a magic bottle, wherein a guide shaft is provided such that a rotation locus of the guide shaft is substantially orthogonal to the guide groove or the guide hole, and the valve body is configured to swing up and down as the operating member is rotated. It is.

(E) Description of the embodiments Figures 1 and 2 show the first embodiment of the present invention.
1 is an exterior body, 2 is a medium bottle housed inside the exterior body, and 3 is a shoulder body fixed to the upper end of the exterior body, and this shoulder body 3 has a mouth 2a of the medium bottle 2 and a mouth rubber 7. The sprue portion 4, the liquid injection port 5, and the handle 6, which are held via the sprue, are integrally molded.

Reference numeral 10 denotes a stopper according to the present invention, which is pivoted to the shoulder body 3 so that it can be opened and closed, for example, by screwing, fitting, or using its rear end as a fulcrum. This stopper 10 is generally composed of a stopper body 11, a valve body 14, and an operating member 20.

The valve body 14 has a valve portion 15 at one end for opening and closing the sprue portion 4, and a seal ring 16 is attached to the outer periphery of the valve portion 15 so as to be in close contact with the upper surface of the sprue portion 4. The center portion of the valve body 14 is attached to a shaft support 12 protruding from the lower surface of the plug body 11 via a support shaft 17 so as to be swingable in the vertical direction. Further, the other end 18 of the valve body 14 is divided into two limbs, and this other end 18
A guide shaft 19 is provided protruding from the inner surface of the holder.

The operating member 20 has a thick disk shape with a knurled outer periphery, and its horizontal central shaft 21 is rotatably supported by a bearing portion 13 of the stopper body 11.
Involute curved guide grooves 22 are formed on both sides of the operating member 20, and the guide shaft 19 of the valve body 14 is slidably engaged with the guide grooves 22. Note that the rotation locus of the guide shaft 19 is substantially orthogonal to the guide groove 22. A part of this operating member 20 is connected to the stopper body 11.
It protrudes from a window hole (not shown) formed at the rear end.

Note that a bottom cover 23 is fixed to the bottom opening of the stopper body 11.

Next, the operation of the stopper 10 having the above configuration will be explained. First, when the valve part 15 closes the sprue part 4, the guide shaft 19 of the valve body 14 as shown in FIG.
is the central axis 21 of the guide groove 22 of the operating member 20.
It is located closest to. Now, when the handle 6 is lifted and the operating member 20 is rotated toward the near side, that is, in the direction of the arrow in FIG. Along with this, the valve body 14 swings clockwise as shown by the dashed line in FIG. Therefore, if the seal ring 16 of the valve part 15 is separated from the sprue part 4 and the main body of the bottle is tilted with the handle 6, the liquid in the medium bottle 2 will be released from the sprue part 4 and the pouring spout 5.
It is poured out through.

To close the valve body 14, the operating member 20 is rotated in the direction opposite to the direction of the arrow in FIG. 2, and the guide shaft 19 is slid toward the center within the guide groove 22.
The valve body 14 swings counterclockwise in FIG. 2, and the seal ring 16 comes into close contact with the sprue 4, thereby closing the sprue 4.

Note that the guide shaft 19 of the valve body 14 is connected to the operating member 20.
The guide groove 22 is located below the central axis 21 of the
has an involute curve shape, and
Since the rotation locus of the guide shaft 19 is approximately orthogonal to the guide groove 22, even if an external force in the clockwise direction in FIG. 2 acts on the valve body 14 with the valve body 14 closing the sprue 4, The operating member 20 does not freely rotate, and the valve body 14
is held stably in the closed position. Therefore, even if the magic bottle falls over by mistake, the impact will damage the valve body 1.
4 will not open and is safe.

(f) Effects of the invention As described above, according to the invention, when opening the valve body, the operating member only needs to be rotated in the vertical direction.
Even if you operate the operating member with the thumb of the hand holding the handle of the magic bottle, no forward rotation moment will be applied to the main body of the magic bottle, and the fluid injection port will not wobble and the streamlines will be disrupted. There is no. In addition, when operating the operating member, the distance between the handle and the operating member does not change, so there is no need to stretch your thumb, and even those with small hands can easily operate the magic bottle. It is safe because the guide shaft of the valve body is fixed by the guide groove (hole) and the valve does not open. Furthermore, since there is no need to provide a spring for biasing a liquid path or a valve body inside the stopper, the internal structure of the stopper is simplified, and a stopper that is easy to assemble and is inexpensive can be obtained.
