DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug having a so-called push-push mechanism for opening and closing an opening of a liquid container.

[0002]

2. Description of the Related Art The applicant of the present invention has previously filed a patent for a liquid container having a built-in push-push mechanism which can be realized with a simple structure (Japanese Patent Laid-Open No. 7-3278).
No. 45).

[0003]

The stopper according to the above-mentioned patent application has an advantage that the structure is simpler than the conventional one, but the operation button pressed down by the user's fingertip is operated in accordance with the opening and closing of the valve body. It also serves as a rotating operation member (sometimes called a mechanism axis, a mechanism rotation axis, etc.) that rotates, as well as being moved up and down by operation of a fingertip. For this reason, when pressing down the operation button with a fingertip, the operation button may be difficult to rotate due to friction with the fingertip,
There was a possibility that opening and closing of the valve body became uncertain.

In addition, a plug provided with a push-push mechanism may cause a user to generate a sound due to collision of components inside the mechanism when operating an operation button to open and close the valve body. Although it is desirable for realizing the opening and closing of the device, conventionally, there was no active sound generation mechanism, and as described above, the push-push mechanism was passive and generated by collision of the components. . For this reason, there is a problem that the sound is indistinct and the user feels that opening and closing is weak.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a stopper for a liquid container which ensures the opening and closing of a valve body and generates a clear sound when the valve is opened and closed.

A valve-opening sliding inclined surface 35 parallel to the inclined surface 33 is formed through an engaging surface 34 that descends downward from the upper end of the inclined surface 33. The above engagement surface 3
4 and the valve-opening slide inclined surface 35 constitute a valve-opening positioning groove 36. The above-described valve-closing slide inclined surface 33 and the valve-opening slide inclined surface 35 are not necessarily parallel, but are desirably parallel in operation described later.

The lower end 3 of the valve opening positioning groove 32
7 is also an inclined surface parallel to the slide inclined surfaces 33 and 35.

On the other hand, on the inner peripheral surface of the guide cylinder 21 of the plug cover 11, a vertical positioning projection 38 is fitted in the valve closing groove 32 at the same pitch as the valve closing positioning groove 32 in the circumferential direction. It is formed to be removable. This positioning projection 38
Is inclined in parallel with the lower end 37 of the valve closing positioning groove 32.

An inward flange 39 is provided at the upper end of the guide cylinder 21 (see FIG. 2).

As shown in FIGS. 2 and 3, the operation button 23 has a cap shape having an outward flange 41. Inside the guide tube 21, the inward flange 39 and the rotary operation member 22 are provided. , And the outward flange 41 is engaged with the inward flange 39 to prevent the guide tube 21 from coming off.

The operation button 23 is put on the rotation operation member 22 by vertically inserting the head 24 of the rotation operation member 22 into the lower end opening portion, and the upper end of the operation button 23 is plugged. It protrudes from the upper surface of the cover 11.

In the valve-closed state in which the positioning projection 38 is fitted in the valve-closing positioning groove 32, as shown in FIG.
There is a slight phase shift P ′ from the triangular waveform unevenness 31 on the rotation operation member 22 side. Also, the small sound projection 43 and the small recess 44 have the same phase shift.

On the other hand, on the upper surface of the stopper cover 11, the guide cylinder 21
An operation button guard 45 slightly surrounding the outside of the cover cover 11 is provided integrally with the plug cover 11, and viewing windows 46 are provided on both sides of a column 47 provided between the insertion button guard 45 and the top surface of the plug cover 11.

Can be seen through the viewing window 45 through the insertion button 23.

Instead of coloring the head 24, character display such as "close" may be performed.

When the rotary insertion member 22 is in the valve closed state, the head 24 can be seen from the outside (see FIG. 5A), and the view port 45 is in the open state. Sometimes, it is provided at a position that cannot be seen through (FIG. 5B)
reference).

The stopper according to the embodiment is as described above.
Next, its operation will be described.

When the user pushes down the top of the operation button 23 with a fingertip in the valve closing state as shown in FIGS. 2 and 4A, the rotary operation member 22 moves down and the valve closing positioning groove 36 is moved. It comes off from the lower end of the positioning projection 38,
At the lower end of the depression stroke, the triangular waveform irregularities 31 on the rotation operation member 22 side mesh with the triangular waveform irregularities 31 ′ on the plug body 9 side. Due to the engagement, the rotation operation member 22 rotates in the direction of arrow A by an amount obtained by subtracting the phase shift P ′ from １ ／ of one pitch of the triangular waveforms 31 and 31 ′, and completely meshes (FIG. 4B )reference).

By the above rotation of the rotary operation member 22, the small sound generating concave portion 44 is fitted to the small sound generating convex portion 43 of the operation button 23. At this time, since the downward force of the fingertip is acting on the operation button 23, the small sound projection 43 and the small recess 4 are generated.
4. A large and clear sound is generated when they are fitted to each other, which makes the user sense the opening of the valve audibly and tactilely through the fingertip.

When the finger is released from the operation button 23, the valve member 14, the rotation operation member 22 and the operation button 23 are pushed upward by the elastic member 18, and the triangular waveform unevenness 31, 3
1 'is disengaged, and the lower end of the positioning projection 38 contacts the valve-opening slide inclined surface 35. The horizontal operating force caused by the inclination angle causes the rotation operating member 22 to rotate in the direction of arrow A, and the positioning projection 38 is moved to the valve-opening positioning groove. Fits 36. Thus, the valve body 14 is prevented from rising, and is kept in the valve-open state (FIG. 4C). At the same time, the fitting of the small sound projection 43 and the small recess 44 is released.

In the above-described valve-open state, the position of the rotary operation member 22 is lower than in the valve-closed state, so that the head 24 cannot be seen through the viewing window 46. Thereby, it can be visually recognized from the outside that the valve is open.

Next, when the operation button 23 is depressed again, the rotary operation member 22 is lowered and its valve opening positioning groove 3 is opened.
6 is disengaged from the lower end of the positioning projection 38, and the triangular corrugations 31 and 31 'mesh with each other to form
Rotate by the same amount as in the above case (see FIG. 4D). As a result, the sounding small convex portion 43 and the small concave portion 44 are fitted again, and a large and clear sound is generated due to the collision at that time, and the user is audibly and tactilely closed as in the above case. Make the valve sense.

When the finger is released from the operation button 23, the valve 1
4. The rotation operation 22 and the operation button 23 are pushed upward by the elastic member 18, and the triangular waveform irregularities 31, 31 'are formed.
Is disengaged, the valve closing slide inclined surface 33 comes into contact with the lower end of the positioning projection 38, and the rotation component 23 rotates in the direction of arrow A by the horizontal component force generated by the inclination angle. As a result, the positioning projection 38 fits into the next valve closing positioning groove 36, and the small sounding projection 43 and the small recess 4
4 is released and returns to the original state (see FIG. 4A).
At this time, the head 24 of the rotary operation member 22 is
Since it rises within 3, it can be visually recognized that the valve is in a closed state by looking at the head 23 from the viewing window 46.

During the operation of the operation button 23 as described above, the small sounding convex portion 43 and the small concave portion 44 generate a large and clear sound when the valve is opened and closed, and the collision of each member can be prevented. Some sound is generated due to contact or the like, but these sounds are indistinct noises compared to the sound when the small sounding protrusion 43 and the small recession 44 are fitted, and should be clearly distinguished. Can be.

[0039]

As described above, in the plug according to the present invention, when operating the operation button with a fingertip, the operation button itself does not rotate, and the rotary operation member rotates according to the vertical movement of the operation button. For this reason, the opening and closing of the valve is not affected by the frictional resistance generated between the operation button and the fingertip, and the valve is reliably opened and closed.

Further, by using the rotation of the rotary operation member with respect to the operation button and fitting the small sound projection and the small recess provided on the opposing surfaces thereof, a clear sound is generated according to the opening and closing of the valve. Therefore, the user can sense opening and closing of the valve by hearing and touch. Further, according to the third aspect of the present invention, it is possible to sense visually.
