Description

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. It is intended to provide a structure.

[0007]

In order to achieve the above object, the present invention takes the following technical means. That is, according to the present invention, a stopper base portion provided at an opening of a container body, an elevating and lowering stopper body vertically movably held with respect to the stopper base portion, and rotatably fitted on the stopper base portion. An operating cylinder is provided, and the lifting / lowering plug is provided with a discharge port at a position exposed from the operating cylinder only when the lifting / lowering plug is raised with respect to the plug base, and between the lifting / lowering plug and the plug base. A stopper means for connecting the discharge port and the opening of the container body when the lifting plug is raised, and for blocking the communication state between the discharge port and the opening of the container body when the lifting plug is lowered. The interlocking means for moving the lifting / lowering plug up and down in accordance with the rotating operation of the operating cylinder is configured between the lifting / lowering plug, the plug base and the operating cylinder.

Further, the interlocking means is constructed so as to hold the lifting / lowering plug body raised by the turning operation of the operating cylinder so as to be able to be pushed down within a range in which the discharge port thereof is not hidden in the operating cylinder. In addition, it is possible to provide a structure in which a spring for urging a pushing-up force is provided to the elevating plug body against the pushing-down operation. In the process of raising the lifting stopper body in the lowered state by the rotating operation of the interlocking means,
The spring can also be configured to be used to push up the lifting plug.

The elevating plug has a driven pedestal and a discharge operating body which is movably connected to the upper part of the driven pedestal and is vertically movable. It is also possible that the spring is loaded in the. In the interlocking device, the stopper base is provided with a cylindrical wall that guides the vertical movement of the lifting / lowering plug body, and the lifting / lowering plug body faces the cylindrical wall of the stopper base and the inner surface of the peripheral wall of the operation cylindrical body. A protruding driven pin is provided, and vertical movement as a composite component is transmitted to the driven pin of the elevating plug on the cylindrical wall of the plug base and the peripheral wall of the operating cylinder by the rotation of the operating cylinder. It is possible to adopt a configuration in which each cam guide path is provided.

The cam guide path provided on the cylindrical wall of the plug base has a vertical path that allows vertical movement of the driven pin of the lifting plug and a lower peripheral path that extends in the circumferential direction at the lower part of the vertical path. The cam guide path provided on the peripheral wall of the operating cylinder is
At least the upper limit of the pushing surface and the pushing back surface for laterally moving the driven pin of the lifting / lowering plug body along the lower peripheral path of the plug base when the operation cylinder is rotated and the vertical movement of the driven pin along the vertical path. It is possible to adopt a configuration in which there is an upper contact surface that is restricted in.

In the cam guide path of the stopper base, the vertical movement of the lifting / lowering stopper body is limited to a predetermined stroke at a tip portion extending in the circumferential direction on the upper side of the vertical path and on the side opposite to the lower peripheral path. An auxiliary vertical path is additionally provided, and when the lifting stopper is rotated after being raised, the engagement of the driven pin is switched to the vertical path or the auxiliary vertical path, so that the lifting stopper is pushed down. In this case, the vertical stroke can be made variable.

Rotation of the operating cylinder about the stopper base is limited by engaging means provided at two or more positions, ie, a front stage position and a rear stage position, and the engaging means at the front stage position is operated at a high level. The height of the contact position of the driven pin with respect to the upper contact surface is different depending on whether the operating cylinder is locked at the front stage position or the rear stage position by applying force. By changing or configuring the engagement of the driven pin with respect to the vertical path and the auxiliary vertical path, it is possible to change the vertical movement stroke when pushing down the elevating plug body.

[0013]

The plug base is integrally provided and fixed to the container body. With respect to this stopper base, the lifting stopper is held so as to be movable up and down, and the operating cylinder is held so as to be rotatable around the stopper base. Then, in the normal state of the liquid container (when not in use), the elevating plug body is in a lowered state and is housed in the operating cylinder body.

In this state, when the operating cylinder is rotated with respect to the container body (plug base), the elevating plug body rises with the operation of the interlocking means, and the discharge port provided in the elevating plug body is opened. It is exposed on the operating cylinder. At this time, the stopper means formed between the lifting stopper and the stopper base brings the discharge port and the mouth of the container body into communication with each other. Therefore, the liquid container can be used (the contents can be taken out).

On the other hand, when the operating tube is rotated in the opposite direction to the above, the lifting stopper is lowered by the reverse operation of the interlocking means.
Therefore, the discharge port of the lifting plug is hidden below the operating cylinder. Further, in this case, the stopper means formed between the lifting stopper and the stopper base block the communication between the discharge port and the mouth of the container body. Therefore, the liquid container is returned to the normal state (closed stopper state in which the contents cannot be taken out).

In this way, the lifting / lowering stopper body is moved in and out by the rotating operation of the operating cylinder, and whether the contents can be taken out or not is switched. The switching state is as follows: It will be apparent at first glance if it is falling. The elevating plug may be configured to be pushed down within a range in which it is restricted that the discharge port is not hidden in the operating cylinder after being raised by the rotating operation of the operating cylinder. In this way, for the lifting plug,
By performing the pressing operation within a predetermined range, the amount of the content taken out by one pressing operation can be substantially quantified. The lifting / lowering plug body after the pushing-down operation can be automatically returned to the original raised position by the spring.

The above-mentioned spring may be used to raise the lifting / lowering plug body when the operating cylinder is rotated, or it may be used only for pushing down the lifting / lowering plug body without using it (the lifting / lowering plug body). May be composed of a driven pedestal and a discharge operation body, and both of them may be vertically movable, and a spring may be loaded therein. It is preferable that the interlocking means has a cam structure in which a driven pin provided on the lifting / lowering plug body and a cam guide path provided on the plug base and the operating cylinder so as to engage with the driven pin are combined. is there. With this cam structure, after the direction of the turning force by the operating cylinder is synthetically changed to the vertical direction, it is taken out as the vertical power for the lifting / lowering plug body.

In this case, the cam guide path provided on the cylindrical wall of the plug base has a vertical path that allows vertical movement of the driven pin of the lifting plug and a lower peripheral path that extends in the circumferential direction at the lower part of this vertical path. Shall have. On the other hand, the cam guide path provided on the peripheral wall of the operating cylinder has a pushing surface and a pushing back surface for laterally moving the driven pin of the lifting stopper engaged with the lower peripheral path of the stopper base when the operating cylinder rotates. And an upper contact surface that limits at least the upper limit of the vertical movement of the driven pin when the driven pin moves to the vertical path.

That is, in the normal state of the liquid container described above, the driven pin of the lifting / lowering plug is engaged with the lower peripheral path of the plug base. When the operating cylinder is rotated from this state, the pushing surface pushes the driven pin in the lateral direction and pushes the driven pin from the lower peripheral path to the vertical path. Then, after the driven pin reaches the vertical path, the lifting / lowering plug body is lifted by the cam action of the pushing surface or the spring action when the spring is used as described above.
Needless to say, the lifting / lowering plug body does not rise above the height at which the driven pin is limited by the upper contact surface.

When the operating cylinder is rotated in the opposite direction from the state where the lifting / lowering plug is raised, the driven pin is pushed downward in the vertical path by the cam action of the pushing back surface. Eventually it is sent to the lower peripheral route. After this, the driven pin is continuously pushed back by the push-back surface and stored in the inner part of the lower circumferential path. Therefore, in this state,
There is no risk that the elevating plug body will return to the state of being arbitrarily projected from the operating cylinder due to the spring action, or that the elevating plug body will be in a protruding state when the liquid container is turned upside down.

In the cam guide path of the plug base, if the auxiliary vertical path is provided at the upper part of the vertical path, the auxiliary vertical path extending in the circumferential direction on the side opposite to the lower circumferential path and facing up and down, is provided. By rotating the body after raising it, the engagement of the driven pin can be switched to either the vertical path or the auxiliary vertical path. If the vertical movement of the lifting stopper is limited to a predetermined stroke that is different from that of the vertical passage as an auxiliary vertical path, the vertical movement stroke when pushing down the lifting stopper can be changed by the above-mentioned switching. it can. That is, the amount of contents to be taken out when the lifting stopper is pushed down can be switched.

In the operation tube body, when rotating around the stopper base, engaging means are provided at two or more positions of the front stage position and the rear stage position so that locking (rotation limitation) can be performed at each position. Can be In this case, the engaging means at the front stage position can be overcome by applying a high operating force to the operating cylinder. In this case, the position where the driven pin abuts the upper contact surface when the operation cylinder is locked at the front stage position and when it is locked at the rear stage position (height dimension at each position is (Different)
Can be changed, or it can be switched whether the driven pin engages with the vertical path or the auxiliary vertical path. Therefore, it is possible to switch the vertical movement stroke when pushing down the elevating plug body, that is, the amount of contents to be taken out when the elevating plug body is pushed down.

FIG. 1A shows a normal state (when not in use) of the liquid container 6, in which the elevating plug 3 is in a lowered state, and most of the excluding upper surface thereof is housed in the operating cylinder 4. There is. Further, FIG. 1B shows a usable state of the liquid container 6, in which the elevating plug body 3 is in a raised state in which it is projected from the operation cylinder body 4 so that the discharge port 3a of the elevating plug body 3 is exposed. Has become.

A stopper means 8 to be described later is formed between the lifting stopper body 3 and the stopper base portion 2, and in the normal state of the liquid container 6 shown in FIG. Mouth 5a
The communication with the discharge port 3a of the lifting / lowering plug body 3 is cut off to make a tightly plugged state. Further, in the usable state of the liquid container 6 shown in FIG. 1B, the stopper means 8 serves as the mouth portion 5 of the container body 5.
a and the discharge port 3a of the elevating plug 3 are communicated with each other.

The lifting / lowering movement of the lifting / lowering stopper body 3 (which also serves as the opening / closing movement of the stopper means 8) can be performed by rotating the operating cylinder body 4, and therefore the lifting / lowering movement is performed. The following interlocking means 10 is configured between the plug body 3, the plug base portion 2, and the operation cylinder body 4. First, in the elevating plug body 3, the outer cylindrical portion 1 in the form of an inverted bottomed cylindrical body is provided.
2 and an inner cylindrical portion 13 provided in a hanging shape at the inner concentric position. Further, on the outer peripheral surface of the lower portion of the exterior tubular portion 12, a pair (two) projecting outwardly in opposite radial directions.
The driven pin 14 is provided. Reference numeral 15 is a stopper pendant which is a component of the stopper means 8.

In the plug base 2, a disc-shaped mounting boss 16 used for mounting the container body 5 on the mouth 5a is provided with a cylindrical wall 17 provided on the upper part thereof.
The water pipe 18 is provided upright at the inner concentric position. The cylindrical wall 17 is provided so as to be capable of being fitted into the exterior cylindrical portion 12 of the elevating plug body 3, and guides the vertical movement of the elevating plug body 3. A pair of cam guide paths 20 into which the driven pins 14 of the lifting plug 3 are fitted are formed on the cylindrical wall 17. These cam guide paths 20 are L-shaped notches formed so as to penetrate the cylindrical wall 17 and pass upward.

The water passage cylinder 18 is provided so as to be closely inserted into the interior cylindrical portion 13 of the elevating plug body 3, and together with the cylindrical wall 17, guides the vertical movement of the elevating plug body 3. A water blocking effect can be obtained between the water passage cylinder 18 and the interior cylinder portion 13. The inside of the water passage cylinder 18 serves as a passage for taking out the contents stored in the container body 5, and the stopper pendant 15 is provided as the elevator stopper body 3 moves up and down.
Becomes a watertight stab (see FIG. 3) or is withdrawn (see FIG. 6). That is, this constitutes the plug means 8.

The mounting boss portion 16 is a ring body having a U-shaped cross section, and an annular middle bottom portion connecting the lower ends of the cylindrical wall 17 and the water passage cylinder 18 is a spring receiving member. 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 cam guide paths 27 which can be engaged with the driven pins 14 of the lifting plug 3. These cam guide paths 27 are formed on the inner peripheral surface of the inner peripheral wall 23 so as to present grooves (recesses) inclined to the circumferential axis. The inner peripheral wall 23 is provided with a fitting rail 22 provided on the mounting boss portion 16 of the plug base 2.
A circumferential groove 30 that can be fitted with is recessed.

The interlocking means 10 is constructed by combining the lifting plug body 3, the plug base portion 2 and the operating cylinder body 4 as described above, and by loading a spring 35 between the lifting plug body 3 and the plug base portion 2. To be done. That is, as shown in FIGS. 3 and 4, with respect to the cylindrical wall 17 of the stopper base portion 2, the elevating stopper body 3 is fitted inside and the operation barrel body 4 is fitted outside.
In this case, the driven pin 14 of the lifting plug 3 is passed through the cam guide path 20 of the plug base 2, and the projecting end of the driven pin 14 is engaged with the cam guide path 27 of the operating cylinder 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.

In this embodiment, the discharge port 3a and the driven pin 14 in the elevating plug 3 have an opening positional relationship of 90 ° in the plane direction as shown in FIGS. However, in FIG. 3, for convenience of description, these discharge ports 3a are
And the driven pin 14 are drawn so as to appear on the same plane. 5 (a) and 5 (b) are operation explanatory views which are clearly shown in a front view of a state where the driven pin 14 is engaged with the cam guide paths 20 and 27 (hatched hatched lines are indicated by hatched lines). , Not for showing the cross section, but for clarifying the outline of each member).

As described above, the cam guide path 20 of the plug base 2
Is an L-shaped notch, and has a vertical path 37 and a lower peripheral path 38 that extends in the circumferential direction at the lower part thereof. The direction in which the lower peripheral path 38 extends with respect to the vertical path 37 is the left side in each of FIGS. 5A and 5B. This is because the operation cylinder 4 is first attached to the stopper base 2 (the normal state of the liquid container 6). To the usable state), the direction of rotation (see arrow X in FIGS. 1 and 5 (a)) in the case of rotating operation is related to the opposite direction. The lower circumferential path 38 is provided with a positioning projection 39 that is located near the extended end thereof and has a diameter corresponding to the diameter of the driven pin 14 and projects into the groove.

On the other hand, as described above, the cam guide passage 27 of the operating cylinder 4 is a groove inclined with respect to the circumferential axis, and the lower step surface inside the groove is the pushing surface 40 and the upper step part. The surface is the pushing back surface 41. Further, in a predetermined region on the upper side of the push-back surface 41, the driven pin 14 of the lifting / lowering plug body 3 acts as an upper contact surface 42. In the cam guide path 27, the inclination direction is such that the left side of each drawing in FIG. 5 is the upper side and the right side is the lower side. This is for rotating the operating cylinder 4 first with respect to the plug base 2. In this case, the engagement position with the driven pin 14 can be gradually increased along the rotation direction (see arrow X).

In the interlocking means 10 having such a structure,
It is assumed that the operating cylinder 4 is rotated in the arrow X direction from the normal state (non-use state) of the liquid container 6 shown in FIG. Along with this, as shown in FIG. 5A, the cam guide path 27 of the operation tube body 4 pushes the driven pin 14 of the elevating plug body 3 laterally by the pushing surface 40 thereof. Therefore, the plug base 2
With respect to the cam guide path 20, the driven pin 14 standing by at the left end position in the lower peripheral path 38 thereof rides over the positioning projection 39 and laterally moves toward the vertical path 37. At this time, of course, the lifting / lowering plug body 3 itself also rotates together with the operating cylinder body 4 (see FIG. 4).

When the driven pin 14 is pushed out to the vertical path 37, the lifting plug 3 is raised at once by the elastic force of the spring 35 as shown in FIG. Therefore, the driven pin 14 rises in the vertical path 37 of the cam guide path 20. During the ascending process, the driven pin 14 moves the pushing surface 4 of the cam guide path 27.
You will be pressing 1. Eventually, the operation tube body 4 will continue to rotate as the lifting plug 3 rises. Of course, the rotation of the operation tube body 4 at this time may be carried out voluntarily as an extension of the operation (without relying on the elastic force of the spring 35).

As described above, the cam guide path 2 is attached to the driven pin 14.
The ascending movement as a synthetic component by 0, 27 is transmitted, and the elevating plug body 3 is in an ascending state with the discharge port 3a exposed as shown in FIG. 1 (b). At this time, the stopper means 8 (see FIG.
In (1), the plug pendant 15 of the lifting / lowering plug body 3 is pulled out from the water cylinder 18 of the stopper base 2, and the mouth 5a of the container body 5 and the discharge port 3a of the lifting / lowering plug body 3 communicate with each other. ,
The contents in the container body 5 can be taken out from the discharge port 3a.

On the other hand, when the operating cylinder 4 is rotated in the opposite direction from this state, the lifted driven pin 14 is lowered by the push-back surface 41 of the cam guide path 27 pushing it laterally. Further, the driven pin 14 is driven from the vertical path 37 of the cam guide path 20 to the lower peripheral path 38.
In this way, the descending movement as a composite component by the cam guide paths 20 and 27 is transmitted to the driven pin, and the elevating plug body 3 returns to the housed state shown in FIG. 1A again. 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.

By the way, in order to prevent the driven pin 14 from slipping upward from the vertical path 37 of the cam guide path 20 when the driven pin 14 is raised, the operating cylinder body 4 has its rotational operation amount limited within a predetermined range. It is structured to be. That is,
As shown in FIG. 5B, a part of the pushing back surface 41 (the above-mentioned upper contact surface 42) in the cam guide path 27 keeps the upper part of the vertical path 37 closed.

As shown in FIG. 7, the rotating operation amount limiting structure has a stopper piece 45 hung vertically to the operating cylinder 4 so as to be circumscribed on the inner peripheral wall 23 thereof, and a rotation of the operating cylinder 4. It is composed of an abutting piece 46 that projects radially outward from the mounting boss portion 16 of the plug base portion 2 so as to collide and interfere with the stopper piece 45 at a predetermined position during movement (see FIG. 4). 47 is a state in which the stopper piece 45 is in contact with the butting piece 46 (that is,
It is an engagement protrusion that holds the liquid container 6 in a usable state).

In the present embodiment, the stopper base is provided so that the standby position of the operating cylinder 4 when the liquid container 6 is in the normal state (non-use state) is mechanically restricted. For the mounting boss 16 of 2, the abutting piece 4
Another abutting piece 48 and an engaging projection 49 were also provided at a position about 180 ° from 6. In addition, the interlocking mechanism 10 shown in the present embodiment is arranged such that, after the lifting plug 3 is lifted as shown in FIG. 1 (b), the lifting plug 3 is within a range in which the discharge port 3a is not hidden inside the operating cylinder 4. It can be pushed down (see Fig. 6). As shown in FIG. 5 (b), the cam guide path 2 of the operating cylinder 4 has a structure that enables such a pressing operation.
7, the flat surface portion 52 is formed in the upper region of the pushing surface 40. That is, the flat surface portion 52 is
When the driven pin 14 is brought into contact with the upper contact surface 42, it has a function of ensuring a predetermined descending allowance space below the driven pin 14. Also, this flat surface portion 5
2 also has an important action in limiting the vertical movement stroke when pushing down the lifting / lowering stopper body 3 at its lower limit.

By pushing down the elevating plug 3 in this manner within a predetermined range, an operation inertia is generated in the elevating plug 3 to prompt the discharge of the contents (for example,
The surface tension or viscosity of the contents generated in the discharge port 3a is shaken off. Since the operation inertia generated in the elevating plug 3 can always be kept the same, the amount of the content taken out by one pressing operation is substantially quantified each time. The lifting / lowering plug body 3 after the pushing-down operation is automatically returned to the original raised position by the spring 35.

FIGS. 8 and 9 show a second embodiment of the spigot device 1 according to the present invention. The difference between the second embodiment and the first embodiment is that the interlocking means 10 is a plug base. The shape and combination of the cam guide path 20 provided on the No. 2 and the cam guide path 27 provided on the operation tube body 4 are present. Note that regarding other configurations, detailed structures, and operations,
Since this embodiment is substantially the same as the embodiment, the same reference numerals are given to those having the same operation, and the detailed description thereof will be omitted.

That is, the cam guide path 20 of the plug base 2 is
It is an L-shaped notch formed by penetrating the cylindrical wall 17 and passing upward, and has a vertical path 37 and a lower peripheral path 38 that extends in the circumferential direction at the lower part thereof. Vertical path 37
An upper bent path 55 extending in the circumferential direction on the opposite side of the lower circumferential path 38 is provided in the upper part of the. This upper bent part 5
5 has a predetermined height in the vertical direction. The vertical path 37 is formed to be slightly inclined with respect to the lower peripheral path 38 toward the upper bent path 55 side.

Further, the cam guide path 27 of the operating cylinder 4 is formed on the inner peripheral surface of the inner peripheral wall 23 to form a stepped portion (recess) which is inclined over about half the circumference thereof.
The lower surface of the stepped portion is the push-back surface 41, and the highest part of the push-back surface 41 is the upper contact surface 4
It is 2. Further, the side surface of the vertical step portion formed at the boundary between the upper contact surface 42 and the push-back surface 41 of the cam guide path 27 (left side in each of FIGS. 9A and 9B) adjacent thereto is the push surface 40. Has been done.

Even if the cam guide passage 20 of the plug base 2 and the cam guide passage 27 of the operating cylinder 4 have the above-described shapes, the driven pin 1 of the lifting stopper 3 is a synthetic component thereof.
4, a predetermined lifting movement is transmitted, and the lifting plug body 3 after being lifted
First, the operation of the interlocking means 10 that the pressing operation (with the stroke corresponding to the upper bend 55) is allowed is
There is no difference from the example.

However, in the second embodiment, when the operating cylinder 4 is rotated from the normal state (non-use state) of the liquid container 6, the driven pin 1 pushed by the pushing surface 40 of the cam guide path 27.
4 is from the lower peripheral path 38 of the cam guide path 20 to the vertical path 37.
This is different from the operation of the first embodiment in that, after being driven out, the lifting is allowed at once without interfering with the pushing surface 40. This difference leads to an advantage that the operation can be performed smoothly and quickly because the operation cylinder 4 does not need to be rotated in the ascending process of the driven pin 14 (the ascending process of the elevating plug 3). Is.

It is in. In addition, the same reference numerals are given to those having the same operations as those of the first embodiment. That is, the lifting and lowering plug body 3 in the third embodiment has a driven base 58 and a discharge operation body 59 connected to an upper portion of the driven base 58 as shown in FIG. A spring 35 is mounted between the upper and lower sides of the operating body 59.

The discharge operation body 59 has an outer cylinder portion 12 and an inner cylinder portion 13, and the discharge port 3 is provided on the upper outer peripheral portion of the outer cylinder portion 12.
a is provided, and the stopper pendant 15 is provided inside the inner tubular portion 13.
Is provided. A pin through hole 62, into which the driven pin 14 is fitted and which allows the vertical movement of the driven pin 14, is formed in the outer peripheral portion of the lower portion of the exterior tubular portion 12. On the other hand, the driven pedestal 58 includes a pedestal main body 58a having a cylindrical shape, and a pair of driven pins 14 projecting radially outward in opposite directions on the lower portion of the outer peripheral surface thereof. As shown in FIG. 11, the pedestal body 5
8 a is formed in such a size that it fits into the peripheral space between the exterior cylinder portion 12 and the interior cylinder portion 13 of the discharge operation body 59. Further, the driven pin 14 has a length that further protrudes radially outward while being fitted in the pin through hole 62 of the discharge operation body 59.

The driven pedestal 58 and the discharge operation body 59 are biased in a mutually separated state by the spring 35, and the ridges 63 are provided on the outer periphery of the upper portion of the pedestal body 58a and the inner periphery of the lower portion of the exterior cylindrical portion 12 respectively. Is held in a non-separable state. Therefore, in the third embodiment, when the operating cylinder 4 is rotated, the lifting plug 3 moves up and down while the driven seat 58 and the discharge operating body 59 are in a mutually separated state.
When the elevating plug body 3 is raised and is pushed down, only the discharge operation body 59 moves up and down with respect to the driven base 58. In this way, the spring 35 is not used for pushing up when the lifting / lowering plug body 3 as a whole rises from the operation tube body 4, but only for restoring when the lifting / lowering plug body 3 (discharging operation body 59) is pushed down. It has been used.

As another structure of the third embodiment, as shown in FIG. 12, in the cam guide path 20 of the plug base 2, an upper bent path 55 is provided above the vertical path 37 (that is, the upper bent path 55 is provided). This point is almost the same as the second embodiment).
And the flat surface portion 5 in the cam guide path 27 of the operation tube body 4.
2 is not formed. These differences are
Both of them are due to the fact that the spring 35 is not used for lifting the lifting plug 3 as a whole as described above, so that the driven pin 14 is always moved while being uniquely positioned by the cam guide paths 20 and 27. It has become.

FIG. 13 shows a first modification of the first embodiment. The difference between the first modification and the first embodiment (see FIG. 5) is that the interlocking means 10 is provided on the plug base 2. It is in the shape of the cam guide path 20 provided. In addition, the same reference numerals are given to those having the same operations as those of the first embodiment. That is, the cam guide path 20 of the first modified example is
An upper peripheral path 66 extending in the circumferential direction on the side opposite to the lower peripheral path 38 is provided above the vertical path 37. Further, an auxiliary vertical path 67 having a predetermined height is provided at the extension destination of the upper circumferential path 66. This auxiliary vertical path 67 is
The up-and-down movement of the driven pin 14 (the lifting plug 3) can be restricted within a predetermined stroke shorter than the vertical path 37.

Therefore, the driven pin 14 is rotated by independently rotating the lifting / lowering plug body 3 after the lifting / lowering plug body 3 is raised with respect to the operation cylinder body 4.
Is engaged with the vertical path 37 (see FIG. 13A) or is engaged with the auxiliary vertical path 67 (FIG. 13B). That is, the lifting plug 3
It is possible to change the vertical movement stroke in the case of pushing down, and by this, the amount of contents to be taken out by pushing down the lifting plug 3 once can be switched to two stages.

FIG. 14 shows a second modification of the first embodiment, and like the first modification (see FIG. 13),
The up-and-down movement stroke when pushing down the lifting / lowering plug body 3 is made variable, but in the second modified example, the cam guide path 20 of the plug base 2 and the cam guide path 27 of the operating cylinder body 4 are made.
The same one as that of the first embodiment (see FIG. 5) is used. In addition, the same reference numerals are given to those having the same operations as those of the first embodiment.

That is, in this second modified example, by adopting a structure in which the rotating operation amount of the operating cylinder 4 is made variable by two engaging means, that is, the front stage position and the rear stage position, FIG. As shown in (a) and (b), the driven pin 14
The height position at which the cam contacts the upper contact surface 42 of the cam guide path 27 (that is, the separation distance between the upper contact surface 42 and the flat surface portion 52) can be changed.

As shown in FIGS. 14C and 14D, the stopper boss 4 of the operating cylinder 4 is attached to the mounting boss 16 of the plug base 2.
5 is provided with an abutting piece 46 and an engaging projection 47 which can be engaged with the engaging projection 4, but in the case of the second modification, the engaging projection 4 is provided.
7, further engaging projections 6 are arranged at a predetermined distance to the front side.
8 are provided. These abutting pieces 46, engaging projections 4
Of the 7, 68, the engaging means for locking the operating cylinder 4 at the rear stage position is the abutting piece 4 as shown in FIG. 14 (d).
6 and the engaging protrusion 47, the stopper piece 45 of the operating cylinder 4
It is configured by locking.

Further, as shown in FIG. 14C, the engaging means for locking the operating cylinder 4 at the front stage position is the stopper piece 45 of the operating cylinder 4 between the engaging projections 47 and 68. It is configured by locking. It should be noted that in the engagement means at the front stage position, a high operation force is applied when the operation tube body 4 is rotated, so that the stopper piece 45 is bent and deformed in the vertical direction, whereby the engagement protrusion 47 is formed. ，
68 can be overcome.

Although not shown, the first modification (see FIG. 13) is shown depending on whether the operating cylinder 4 is locked at the front stage position or the rear stage position as described above. As described above, the driven pin 14 can be switched between the vertical path 37 and the auxiliary vertical path 67.

FIG. 15 shows a first modification of the second embodiment. The first modification is the most different from the second embodiment (see FIG. 9) in that the interlocking means 10 is provided in the plug base 2. It is in the shape of the cam guide path 20 provided. In addition, the cam guide path 27 of the operation tube body 4 has the second embodiment (see FIG. 9).
The same thing as is used. In addition, the same reference numerals are given to those having the same operations as those of the second embodiment.

That is, the cam guide path 2 of the first modified example.
In No. 0, an upper peripheral path 66 is provided following the upper bent path 55 at the upper part of the vertical path 37, and an auxiliary vertical path 67 having a predetermined height is provided at the extension tip of the upper peripheral path 66. ing. The auxiliary vertical path 67 can limit the vertical movement of the driven pin 14 (lifting plug body 3) within a predetermined stroke that is slightly longer than the vertical path 37 (upper bent path 55).

Therefore, by rotating the lifting / lowering plug body 3 after it has been raised with respect to the operating cylinder 4, the driven pin 14
Is engaged with the upper bent path 55 (see FIG. 15A) of the vertical path 37 or with the auxiliary vertical path 67 (FIG. 15B). That is, it is possible to change the vertical movement stroke when pushing down the lifting / lowering plug body 3, whereby the amount of the contents to be taken out by pushing down the lifting / lowering plug body 3 once can be switched to two stages. it can.

FIG. 16 shows a second modification of the second embodiment, and like the first modification (see FIG. 15),
The stroke of vertical movement when the lifting plug 3 is pushed down is variable. In this second modified example, the cam guide path 20 of the plug base 2 is adapted to be directly connected to the auxiliary vertical path 67 from the upper bent path 55 at the upper part of the vertical path 37. The cam guide path 27 of the operating cylinder 4 is substantially the same as that of the second embodiment (see FIG. 9). In addition, the same reference numerals are given to those having the same operations as those of the second embodiment.

In this second modification, the operating cylinder 4
By adopting a structure in which the rotation operation amount of the driven pin 14 can be changed by two engaging means at the front stage position and the rear stage position, the driven pin 14 can move the driven pin 14 to the upper bent path 55 (FIG.
6 (a)) or the auxiliary vertical path 67.
It is possible to switch whether to engage (FIG. 16 (b)).

The engaging means at the front stage position and the engaging means at the rear stage position have the same structure as that of the second modified example of the first embodiment (see FIGS. 14 (c) and 14 (d)), and also have an action. Since they are the same, detailed description is omitted here. 17 (a) shows a fourth embodiment of the plug device 1 according to the present invention, and FIG. 17 (b).
Shows a fifth embodiment of the plug device 1 according to the present invention.
In the fourth embodiment and the fifth embodiment, in the stopper means 8 formed between the lifting stopper body 3 and the stopper base 2,
Different from the embodiment. In addition, the same reference numerals are given to those having the same operations as those of the first embodiment.

That is, in the stopper means 8 of the fourth embodiment shown in FIG. 17A, the mounting boss portion 16 of the stopper base 2 is
A cylindrical water blocking partition 72, which can be contacted in a watertight manner on the inner peripheral surface of the exterior tubular portion 12 of the elevating plug body 3, is provided upright.
In addition, at the bottom of the inner peripheral portion of the water blocking partition 72, the container body 5
There is provided a middle bottom portion 73 which closes the mouth portion 5a and is bulged so that it can come into watertight contact with the inner peripheral surface of the inner tubular portion 13 when the lifting plug 3 is lowered. A plurality of water passage holes 74 are formed in the middle bottom portion 73 around the bulging portion at predetermined intervals.

Therefore, when the lifting stopper 3 is descending,
Between the outer cylinder 12 and the water blocking partition 72, between the inner cylinder 13 and the inner bottom 73, and between the inner cylinder 13 and each water passage hole 74.
A sealed state can be obtained between above and below. When the elevating plug 3 is raised, the circumference of the inner tubular portion 13 and the inner bottom portion 73 and the upper and lower portions of the inner tubular portion 13 and each water passage hole 74 are in communication with each other.

On the other hand, in the stopper means 8 of the fifth embodiment shown in FIG. 17B, the mounting boss portion 16 of the stopper base 2 is watertight on the outer peripheral surface of the inner cylindrical portion 13 of the lifting stopper body 3. A cylindrical water blocking partition wall 77 that can come into contact with each other is erected. Further, an inner bottom portion 78 capable of closing the mouth portion 5a of the container body 5 is provided in the lower portion of the inner peripheral portion of the water blocking partition wall 77, and the middle bottom portion 78 is provided with a rising edge portion of the water blocking partition wall 77 from each other. A plurality of water passage holes 79 are formed at predetermined intervals.

Therefore, when the lifting plug 3 is descending,
Between the circumference of the interior tubular portion 13 and the water blocking partition 77, and the interior tubular portion 1
A tightly plugged state can be obtained between the upper and lower sides of 3 and each water passage hole 79. Further, when the lifting plug 3 is lifted, the upper and lower portions of the interior tubular portion 13 and each water passage hole 79 are in communication with each other. FIG. 18 shows a sixth embodiment of the plug device 1 according to the present invention. In the sixth embodiment, the operating cylinder 4 has a peripheral wall 23 having a single wall structure. This is different from the embodiment (the first embodiment has a double wall structure of the inner peripheral wall 23 and the outer peripheral wall 25 as shown in FIG. 3). In addition, the same reference numerals are given to those having the same operations as those of the first embodiment.

The present invention is not limited to the above-mentioned embodiments, and various detailed improvements and changes can be added. For example, in the interlocking means 10, by gradually changing the lead angles of the cam guide paths 20 and 27 provided in the plug base 2 and the operating cylinder 4, the amount of rotation operation of the operating cylinder 4, the operating torque, and the lifting plug 3 It is possible to change various lifting strokes and the like.

Further, in the interlocking means 10, the driven pin 1
It is also possible to make the combination of 4 and the cam guide paths 20, 27 into only one set, or in three or more sets. It is also possible to adopt a structure in which the elevating plug body 3 is not pushed down after being lifted from the operating cylinder body 4, and in this case, the spring 35 does not necessarily have to be loaded. That is, it is possible to control the lifting operation of the lifting / lowering plug body 3 only by the combined components of the cam guide paths 20 and 27.

In the case of limiting the amount of rotary operation of the operating cylinder 4, the structure of the engaging means can be selected as appropriate, and
The number of the engaging means is not limited to two, that is, the front position and the rear position. When the container body 5 is made of resin or the like, it is possible to integrally form the plug base portion 2 with respect to the opening 5a of the container body 5.

The liquid stored in the container body 5 is not limited at all.

[0073]

According to the present invention, which has the above-described structure, the stopper base is integrally provided with the container body, and the lifting stopper is vertically movable with respect to the stopper base. The operation cylinder is held so as to be rotatable around the stopper base. Then, in the normal state (non-use state) of the liquid container, the elevating plug body is in the descending state and is housed in the operating cylinder body. In this state, the container body (plug base)
On the other hand, when the operating cylinder is operated to rotate, the elevating plug is raised in association with the operation of the interlocking device, and the discharge port provided in the elevating plug is exposed on the operating cylinder. At this time, the stopper means formed between the lifting stopper and the stopper base brings the discharge port and the mouth of the container body into communication with each other, so that the liquid container is ready for use. On the other hand, when the operating cylinder is rotated in the opposite direction to the above, the lifting plug is lowered by the reverse operation of the interlocking means, and the discharge port of the lifting plug is hidden below the operating cylinder again. Further, in this case, since the plug means blocks the communication between the discharge port and the opening of the container body, the liquid container is returned to the normal state (unused state).

As described above, unlike the prior art, it is not necessary to unscrew the outer lid each time the liquid container is used and screw it into the liquid container after use, so that the liquid container is extremely easy to handle. Of course, there is no defect such as dropping the screwed outer lid to damage or lose it. In this way, the lifting / lowering stopper body is taken in and out by the turning operation of the operating cylinder, and whether the contents can be taken out or not is switched.The switching state is such that the lifting stopper body is raised or lowered. It will be apparent at first glance. Therefore, there is no failure such as accidentally laying down the liquid container that is not hermetically sealed, and leakage of the contents can be prevented.

The elevating plug body is constructed so that it can be pushed down within a range within which the discharge port is not hidden within the operating cylinder body after being raised by the rotating operation of the operating cylinder body. You can In this way, by causing the lifting / lowering stopper body to perform the pushing-down operation within a predetermined range, the amount of the content taken out by one pushing-down operation can be substantially quantified.

As the structure of the interlocking means, a cam structure in which a driven pin provided on the lifting / lowering plug and a cam guide path provided on the plug base and the operating cylinder so as to engage with the driven pin are combined is used. Is preferred. This cam structure, after synthetically changing the direction of the turning force by the operating cylinder to the vertical direction,
It is taken out as vertical power for the lifting plug, and has the advantages of being structurally simple and excellent in conversion efficiency. Therefore, the manufacturing cost is reduced,
The operation can be ensured and the life can be extended.

In the cam guide path provided in the stopper base, if the auxiliary vertical path that is parallel to and communicates with the vertical path is provided in the cam guide path, the lifting pin is rotated after it is lifted to engage the driven pin. It is possible to switch between the vertical path and the auxiliary vertical path. If the vertical movement of the lifting stopper is limited to a predetermined stroke that is different from that of the vertical passage as an auxiliary vertical path, the vertical movement stroke when pushing down the lifting stopper can be changed by the above-mentioned switching. it can. That is, the amount of contents to be taken out when the lifting stopper is pushed down can be switched as desired.

In the operation cylinder body, when rotating around the stopper base, engaging means are provided at two or more positions of the front stage position and the rear stage position so that locking (rotation restriction) can be performed at each position. The engaging means at the front stage position can be overcome by applying a high operating force to the operating cylinder.
The position where the driven pin abuts the upper contact surface when the operating cylinder is locked at the front stage position and when it is locked at the rear stage position (the height dimension may be different for each position). Or the driven pin is engaged with the vertical path or the auxiliary vertical path.
Even in the case of such a configuration, the vertical movement stroke when pushing down the lifting / lowering plug, that is, the amount of contents to be taken out when pushing down the lifting / lowering plug can be switched as desired. It is a thing.
