Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper device which can be applied to a liquid container containing, for example, a lotion.

[0002]

2. Description of the Related Art Conventionally, as a liquid container for containing lotion or the like, there has been a container body made of glass or resin in which an inner stopper made of soft resin is fitted at its mouth. A minute water injection hole communicating with the inside of the container body is formed in this inner stopper, and the contents (lotion etc.) can be taken out by shaking the container body upside down.

In this type of liquid container, an outer lid, which covers the inner plug and enables the water injection hole to be tightly closed, can be externally fitted and screwed around the mouth of the container body. Of course, this outer lid is to be unscrewed from the container body in advance when the contents are taken out.

[0004]

In the conventional liquid container,
It is necessary to unscrew the outer lid for each use and screw it together after use. Therefore, it was troublesome. In addition, the screwed outer lid may be dropped and damaged or lost. Further, in the conventional liquid container, there is a problem that the amount of the content taken out by one swing of the container main body is not constant depending on the size of the shaking behavior.

Further, in the conventional liquid container, the outer lid is covered, but it is not completely screwed (that is, it is in a loose state, and the water injection hole of the inner plug cannot be sealed. Even if it was in (state), it could not be confirmed only by looking at it. Therefore, if the liquid container is made to reach sideways with the incompletely screwed state as described above, there is a problem that the contents are spilled.

The present invention has been made in view of the above circumstances, and by eliminating the need for screwing or unscrewing the outer lid,
In addition to facilitating handling, the contents can be taken out almost quantitatively, and at the first glance it can be confirmed whether or not they are in a tightly plugged state so that the contents can be prevented from leaking. The purpose is to provide a device.

[0007]

A first technical means of the present invention for solving this technical problem is a stopper base 2 provided at an opening 5a of a container body 5 and a vertical movement with respect to the stopper base 2. A lifting and lowering plug body 3 that is freely held and an operating cylinder body 4 that is rotatably fitted to the stopper base 2 are provided, and a spring 35 that biases a lifting force to the lifting and lowering plug body 3 is provided. The lifting plug 3 is provided
Is provided with a discharge port 3a at a position exposed from the operating cylinder 4 only when the plug base 2 is raised.
And the plug base 2, the discharge port 3a is communicated with the opening 5a of the container body 5 when the lifting / lowering plug body 3 is raised, and the discharge port 3a and the container body 5 are lowered when the lifting / lowering plug body 3 is lowered. The stopper means 8 for blocking the communication state with the mouth portion 5a of the plug is provided, the engaging portion 14 is provided on the lifting stopper body 3, and resists the pushing force of the spring 35 when the lifting stopper body 3 is lowered. Lift plug 3
Is provided with a locking portion 28 for engaging and disengaging the engaging portion 14 in a disengageable manner.

The second technical means of the present invention is that the engaging portion 14 is disengaged from the engaging portion 28 by the turning operation of the operating cylinder 4. According to a third technical means of the present invention, the locking portion 28 is provided on the operation cylinder body 4,
A cylindrical wall 17 for guiding the vertical movement of the lifting / lowering stopper body 3 to the stopper base portion 2.
Is provided, and the tubular wall 17 is provided with a guide path 20 that guides the engaging portion 14 to the locking portion 28 when the lifting plug 3 is lowered.

[0009]

When the contents are taken out from the liquid container 6, the operation cylinder 4 may be rotated from the normal state (non-use state) of the liquid container 6. When the operating cylinder 4 is rotated, the engaging portion 14 is disengaged from the locking portion 28, the lifting plug 3 is lifted by the elastic force of the spring 35, and the discharge port 3a is exposed to the outside. It becomes a state. At this time, the opening 5a of the container body 5 and the discharge port 3a of the elevating plug 3 are in communication with each other.

On the other hand, when the liquid container 6 is brought into the normal state (non-use state), when the elevating plug body 3 is pressed downward from the raised state where the discharge port 3a is exposed, the elevating plug body 3 pushes up the spring 35. Falls against. Then, the engaging portion 14 engages with the locking portion 28 from the lower side, and the lifting / lowering plug body 3 is held in the lowered state with respect to the operating cylinder body 4 to the plug base portion 2 so as not to move upward.
At this time, the mouth portion 5a of the container body 5 and the discharge port 3 of the elevating plug body 3
The communication state with a is cut off.

When the elevating plug 3 is pressed downward as described above, the liquid container 6 is tilted so that the discharge port 3a is on the lower side until the discharge port 3a is covered with the contents.
By pushing down the elevating plug 3 by a predetermined stroke, it is possible to substantially quantify the amount of the content taken out by causing a substantially constant volume reduction in the liquid container 6.

May become a watertight stab (see FIG. 1) or be pulled out (see FIG. 2). That is, this constitutes the plug means 8.

The mounting boss portion 16 is a ring-shaped member having a U-shaped cross section, and an annular middle bottom portion connecting the lower ends of the tubular wall 17 and the water passage 18 has a spring bearing. Zodiac 2
It is supposed to be 1. In addition, a fitting rail 22 that extends around the cylindrical wall 17 is formed on the attachment boss portion 16. On the other hand, in the operation cylinder 4, an inner peripheral wall 23 that can be externally fitted to the cylindrical wall 17 of the stopper base 2 in a rotatable state, and an upper peripheral flange portion 24 are provided on the inner peripheral wall 23. And an outer peripheral wall 25 provided so as to surround the inner peripheral wall 23.

The inner peripheral wall 23 is formed with a pair of guide passages 27 which can be engaged with the engaging portions 14 of the elevating plug body 3. These guide passages 27 are formed so as to present vertical grooves (recesses) on the inner peripheral surface of the inner peripheral wall 23. A locking portion 28 that engages the engaging portion 14 in the guide path 27.
Is protruding. The locking portion 28 has an inclined surface 28a whose upper portion gradually becomes thinner.

The inner peripheral wall 23 is provided with a peripheral groove 30 which can be fitted with the fitting rail 22 provided on the mounting boss portion 16 of the plug base 2. That is, as shown in FIGS. 1 and 6, with respect to the cylindrical wall 17 of the stopper base portion 2, the elevating stopper body 3 is fitted inside, and the operating cylinder body 4 is fitted outside. In this case, the engaging portion 14 of the lifting stopper 3 is inserted into the guide passage 20 of the stopper base 2, and the tip of the engaging portion 14 is inserted into the guide passage 27 of the operation tube body 4. Further, the spring 35 is formed by the peripheral space formed by the tubular wall 17, the water passage 18 and the spring seat 21 in the plug base 2, and the outer tubular part 12 and the inner tubular part 13 in the lifting plug body 3. It is loaded in the upper and lower spaces surrounded by the surrounding space.

Therefore, the spring 35 applies a pushing force to the lifting / lowering plug body 3, and when the lifting / lowering plug body 3 descends, the engaging portion 14 rides over the inclined surface 28a of the locking portion 28 to the locking portion 28. The engaging portion 14 and the locking portion 28 constitute engaging means for holding the elevating plug body 3 in a lowered state against the pushing force of the spring 35. Has been done.

In this embodiment, the discharge port 3a and the engaging portion 14 of the elevating plug 3 have an opening positional relationship of 90 ° in the plane direction as shown in FIG. However,
In FIG. 1, for convenience of description, the discharge port 3a and the engaging portion 1 are shown.
It is drawn so that 4 and 4 appear on the same plane. FIG. 5 (a)
3A and 3B are operation explanatory diagrams that are shown in a plain manner in the form of a front view of the guide path 20 and the guide path 27 (hatched hatched lines do not represent a cross section, but the outline of each member). It is for clarity).

The guide path 20 of the plug base 2 is a vertical path 37.
And an inclined path 38 and an L-shaped upper path 39. In the configuration as described above, the operating cylinder 4 is moved from the normal state (non-use state) of the liquid container 6 shown in FIG.
Rotate in the direction. Along with this, as shown in FIG. 5 (a), the guide passage 27 and the locking portion 28 of the operating cylinder 4 are not
Move in the X direction. Therefore, as shown in FIG. 5B, the engaging portion 14 is disengaged from the locking portion 28, and the lifting / lowering plug body 3 can be moved upward relative to the plug base portion 2. As a result, the elevating plug body 3 is lifted at once by the elastic force of the spring 35. At this time, the engaging portion 14 is connected to the guide passage 20 of the stopper base 2.
When the engaging portion 14 moves upward along the inclined path 38 of the guide path 20 along the upper path 39, the elevating plug body 3 moves in a direction opposite to the arrow X direction with respect to the plug base 2. While moving, the engaging portion 14 presses the step surface 40 of the guide path 27 in the direction opposite to the arrow X direction, whereby the operating cylinder 4 is opposed to the plug base 2 in the arrow X direction. Return to the direction and rotate.

In this way, when the lifting / lowering plug body 3 moves upward with respect to the plug base 2, the lifting / lowering plug body 3 is in a raised state with the discharge port 3a exposed as shown in FIG. 4 (b). At this time, in the stopper means 8 (see FIG. 2), the water pipe 1 of the stopper base 2 is
8, the pendant body 15 of the elevating plug body 3 is pulled out, and the mouth portion 5a of the container body 5 and the discharge port 3 of the elevating body 3 are opened.
Since it communicates with a, the contents in the container body 5 can be taken out from the discharge port 3a.

On the other hand, as shown in FIG. 4B, the discharge port 3a
When the lifting / lowering plug body 3 is pressed downward from the raised state in which the is exposed, the lifting / lowering plug body 3 is lowered against the pushing force of the spring 35. At this time, the raised engaging portion 14 descends along the guide path 20 of the stopper base 2, and when the engaging portion 14 moves down the inclined path 38 of the guide passage 20, the lifting stopper body 3 moves. To the arrow X direction, the engaging portion 14 slides over the locking portion 28 over the inclined surface 28a, and the engaging portion 14 engages with the locking portion 28 from below. To meet. Due to this engagement, the elevating plug body 3 is held in a lowered state so as not to be able to move upward relative to the operating cylinder body 4 or the plug base portion 2. In this way, when the lifting / lowering plug body 3 moves downward with respect to the plug base 2, the lifting / lowering plug body 3 returns to the stored state shown in FIG. 4A. At this time, in the stopper means 8 (see FIG. 3), the stopper pendant 15 of the lifting stopper body 3 is pierced into the water passage 18 of the stopper base 2, and the mouth portion 5 a of the container body 5 and the lifting stopper body 3 are inserted. Since the communication with the discharge port 3a is blocked, the contents in the container body 5 will not be spilled even if the liquid container 6 is laid on its side or upside down.

When the elevating plug body 3 is pressed downward as described above, the liquid container 6 is tilted so that the discharge port 3a is on the lower side until the discharge port 3a is covered with the contents.
Due to the volume decrease in the container body 5 due to the lowering operation of the elevating plug 3, the surface tension or viscosity of the contents generated in the discharge port 3a is given an action of shaking off the surface tension or viscosity of the container main body 5. The contents can be taken out. On this occasion,
The elevating plug 3 can be pushed down to the maximum with the stroke shown in FIG. 5, but by limiting the pushing down of the elevating plug 3 to a predetermined stroke, the amount of the content taken out by one pushing operation can be approximately quantified. can do.

By the way, in order to prevent the engaging portion 14 from slipping upward from the guide passage 20 and the guide passage 27 when the engaging portion 14 is raised, the operating cylinder body 4 has its rotation operation amount limited within a predetermined range. It is structured to be. That is, FIG.
As shown in (a), the step surface 40 of the guide path 27 closes the upper part of the guide path 20, and the step surface 41 of the guide path 20 keeps the upper part of the guide path 27 closed. ing.

As shown in FIG. 1 and FIG. 6, this structure for limiting the amount of rotation operation has a stopper piece 45 vertically hung on the operating cylinder 4 so as to circumscribe the inner peripheral wall 23, and an operating cylinder. 4 comprises an abutting piece 46 which projects radially outward from the mounting boss portion 16 of the plug base 2 so as to collide with and interfere with the stopper piece 45 at a predetermined position when the operation cylinder 4 is rotated. Four
The rotation amount with respect to the plug base portion 2 is regulated within the range of arrow C shown in FIG.
