Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spout device with a pump 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 a lotion or the like, there is a container body made of glass or resin and having a pump device attached to its mouth. In this pump device, the contents (lotion, etc.) can be taken out by pushing down the elevating head held in a raised state by a spring.

By the way, in this type of liquid container, if the elevating head is erroneously pressed down or the elevating head is pushed in when the liquid container is dropped, the contents are discharged and wasted. was there. In particular, when the liquid container is dropped, the pump device may be broken. Therefore, in order to solve these problems, there is a type in which an outer lid that covers the entire pump device (ascended lift head) 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 having an outer lid attached, it is needless to say that the outer lid must be unscrewed before use and screwed after use. Therefore, it was troublesome. In addition, the screwed outer lid may be dropped and damaged or lost.

The present invention has been made in view of the above circumstances, and by eliminating the need for screwing or unscrewing the outer lid,
It is an object of the present invention to provide a cap structure with a pump for a liquid container, which facilitates handling and can prevent waste of contents due to malfunction of a pump device and failure of the pump device. .

[0006]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention relates to a plug base portion provided at the mouth of a container body, a pump device that is vertically movable with respect to the plug base portion, and an operation that is rotatably fitted to the plug base portion. A tubular body, and the pump device is provided with a discharge port at a position exposed from the operating tubular body only when the pump device is raised with respect to the stopper base,
Between the pump device, the plug base, and the operating cylinder, an interlocking device for moving the pump device up and down in accordance with the turning operation of the operating cylinder is configured.

In the interlocking device, the stopper base is provided with a cylindrical wall for guiding the vertical movement of the pump device.
The pump device is provided with a cylindrical wall of the stopper base and a driven pin protruding toward the inner surface of the peripheral wall of the operating cylinder, and the operating cylinder is provided on the cylindrical wall of the plug base and the peripheral wall of the operating cylinder. The driven pin of the pump device may be provided with a cam guide path for transmitting the vertical movement as a combined component by the rotation of the body.

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 pump device, and an upper peripheral path that extends in the circumferential direction at the upper part of the vertical path, 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 pump device along the upper peripheral path of the plug base when the operating cylinder is rotated. It can be configured.

[0009]

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

In this state, when the operating cylinder is rotated with respect to the container body (plug base), the pump device is raised in association with the operation of the interlocking means, and the discharge port provided in this pump device operates the operating cylinder. It becomes exposed on the body. Therefore, the pump device can be operated (the liquid container can be used). On the other hand, if the operating cylinder is rotated in the opposite direction to the above,
The pump device descends due to the reverse operation of the interlocking means. Therefore, the discharge port of the pump device is hidden below the operating cylinder. Therefore, the pump device is returned to the inoperable state (normal state of the liquid container).

In this way, the pump device is moved in and out by the turning operation of the operating cylinder to switch whether the contents can be taken out or not. The switching state is such that the pump device is raised or lowered. At first glance it becomes clear. It is preferable that the interlocking means has a cam structure in which a driven pin provided in the pump device and a cam guide path provided in the plug base and the operating cylinder so as to engage with the driven pin are combined. . With this cam structure, the direction of the turning force generated by the operating cylinder is synthetically converted to the vertical direction, and then extracted as vertical power for the pump device.

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 pump device, and an upper peripheral path that extends in the circumferential direction above the vertical path. It is assumed that 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 pump device, which is engaged with the upper peripheral path of the plug base, when the operating cylinder rotates. Shall have.

That is, in the normal state of the liquid container described above, the driven pin of the pump device is located at the lower end of the vertical path of the cam guide path of the plug base. When the operating cylinder is rotated in this state, the pushing surface of the cam guide path provided on the operating cylinder pushes the driven pin in the lateral direction, so that the driven pin is restrained from lateral movement by the vertical path. As a result, it rises and is eventually driven from the vertical route to the upper circumferential route. In this way, the pump device rises.

When the operating cylinder is rotated in the opposite direction from the state where the pump device is raised, the driven pin whose push-back surface is engaged with the upper circumferential path is pushed back toward the vertical path, You will be driven to this vertical path. Then, the driven pin continues to be lowered by the cam action of the push-back surface, and is eventually driven to the lower end of the vertical path. In this way, the pump device descends.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show the overall structure of a first embodiment of a stopper device 1 according to the present invention. The stopper device 1 includes a stopper base 2 and a stopper base 2 as shown in FIG. The pump device 3 is held so as to be movable up and down with respect to 2, and the operating cylinder body 4 is externally fitted and held so as to be rotatable around the plug base 2.

The spigot device 1 is integrally attached to the spout 5a of the container body 5 by the spigot base 2 (by screw connection, undercut structure or adhesion), and in this case, the liquid container 6 as a whole. Is configured.
The pump device 3 has a pump body 7 and an elevating head 8 attached to the upper end portion of the piston rod 7a of the pump body 7, and the elevating head 8 is attached to the pump body 7. By pushing down,
The contents stored in the container body 5 can be sucked up through the lower suction pipe 7b of the pump body 7 and taken out from the discharge port 3a provided on the upper outer peripheral portion of the elevating head 8.

FIG. 1A shows the normal state (when not in use) of the liquid container 6, the pump device 3 is in a lowered state, and most of the lifting head 8 except the upper surface is housed in the operating cylinder 4. It has become so. Further, FIG. 1B shows a usable state of the liquid container 6, and the pump device 3 is in a raised state in which the elevating head 8 projects from the operation cylinder body 4, and the discharge port 3
a is exposed.

The above-mentioned vertical movement of the pump device 3 can be performed by rotating the operating cylinder 4, and therefore, between the pump device 3, the plug base 2 and the operating cylinder 4. The interlocking means 10 as shown below is configured.
First, in the pump device 3, a socket 11 is externally fixed to the pump body 7. The upper portion of the socket 11 is enlarged in diameter around the piston rod 7a, and this enlarged diameter portion serves as a guide wall 12 capable of guiding and holding the vertical movement of the elevating head 8. Note that reference numeral 13 shown in FIG.
Is a concavo-convex engaging portion used to prevent rotation of the elevating head 8, and reference numeral 13 a shown in FIG. 2 is a notch that constitutes one part of the concavo-convex engaging portion 13.

On the outer peripheral surface of the lower portion of the guide wall 12, there are provided a pair of (two) driven pins 14 projecting outward in the opposite radial directions. In the plug base 2,
A cylindrical wall 17 is provided on an upper portion of a disc-shaped attachment boss portion 16 used for attaching the container body 5 to the mouth portion 5a. The tubular wall 17 is formed so that the guide wall 12 of the pump device 3 can be fitted therein, and guides the vertical movement of the pump device 3. A pair of cam guide paths 20 into which the driven pins 14 of the pump device 3 are fitted are formed on the cylindrical wall 17. These cam guide paths 20 are crank-shaped notches formed so as to penetrate the cylindrical wall 17 and pass upward.

The mounting boss portion 16 is a ring body having a U-shaped cross section, and a fitting rail 22 is formed on the outer peripheral surface thereof so as to project therefrom. Further, 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 inner peripheral wall 23 is provided so as to surround the inner peripheral wall 23 via an upper peripheral collar portion 24. The outer peripheral wall 25 is formed. A pair of cam guide passages 27 that can be engaged with the driven pins 14 of the pump device 3 are formed on the inner peripheral wall 23. The cam guide passages 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 about the half circumference thereof.

A peripheral groove 30 is formed on the inner peripheral surface of the lower portion of the inner peripheral wall 23 so as to be engageable with the engaging rail 22 provided on the mounting boss portion 16 of the plug base 2. The interlocking means 10 is, as shown in FIGS. 3 and 4, a cylindrical wall 1 of the plug base 2.
7, the pump device 3 is fitted inside and the operating cylinder 4 is fitted outside.
The driven pin 14 of the pump device 3 is connected to the cam guide path 2 of the stopper base 2.
0, and the protruding end of the driven pin 14 is engaged with the cam guide path 27 of the operating cylinder body 4.

In this embodiment, in the pump device 3, the discharge port 3a and the driven pin 14 have an opening positional relationship of 90 ° in the plane direction as shown in FIGS. However, in FIG. 3, for convenience of explanation, these discharge ports 3
It is drawn so that a and the driven pin 14 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 a crank-shaped cutout, and includes a vertical path 37, a lower peripheral path 38 extending in the circumferential direction at the lower part thereof, and an upper peripheral path extending at the upper part of the vertical path 37 in the circumferential direction opposite to the lower peripheral path 38. And 39. Lower peripheral path 38 is vertical path 3
The direction of extension with respect to 7 is the left side of each drawing of FIG. 5, and the upper circumferential path 39 is the right side of the same. In the lower circumferential path 38, this is the rotation direction when the operation cylinder 4 is first rotated with respect to the stopper base 2 (in order to switch from the normal state of the liquid container 6 to the usable state) (see FIG. 1 and It is related to the direction opposite to the arrow X in FIG. 5A and the same direction as the above-described rotation direction (see arrow X) in the upper circumferential path 39.

A projection 38a is formed in the lower peripheral path 38 near the bent corner with the vertical path 37, and in the upper peripheral path 39, near the bent corner with the vertical path 37. The protrusion 39a is formed. These protrusions 38a, 39a
Are for retaining the retained state of the driven pin 14 with respect to the lower peripheral path 38 or the upper peripheral path 39.

On the other hand, as described above, the cam guide path 27 of the operating cylinder 4 is a groove inclined with respect to the circumferential axis, and the lower step portion surface inside the groove is the pushing surface 40, and the upper step portion. The surface is the pushing back surface 41. Further, in the predetermined region on the upper side of the push-back surface 41, the driven pin 14 of the pump device 3 is
On the other hand, it functions as the 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 FIGS. 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 pump device 3 laterally by the pushing surface 40 thereof. for that reason,
With respect to the cam guide path 20 of the stopper base 2, the driven pin 14 initially engaged with the lower peripheral path 38 of the plug base section 2 starts to laterally move, gets over the protrusion 38a for retaining, and is expelled to the vertical path 37. become. At this time, of course, the pump device 3
The device itself also rotates together with the operating cylinder 4 (see FIG. 4).

If the operating cylinder 4 continues to rotate, the pushing surface 40
The sideways pushing of the driven pin 14 is continued by the driven pin 14
Moves up in the vertical path 37. Then, when the height corresponding to the upper circumferential path 39 is reached, it is driven into the upper circumferential path 39 by overcoming the retaining projection 39a. As described above, the cam guide paths 20 and 27 are provided with respect to the driven pin 14.
As a result, the pump device 3 is in a rising state in which the discharge port 3a is exposed as shown in FIGS. 1B and 6. Of course, in this state, the driven pin 14 is constrained by the upper circumferential path 39 so that it cannot move up and down.
The pump device 3 is also held in a state in which the vertical movement (particularly downward movement) is blocked.

On the other hand, when the operating cylinder 4 is rotated in the opposite direction from this state, the push-back surface 41 of the cam guide path 27 causes the driven pin 14 to move in the opposite direction to the above as shown in FIG. 5B. As it is pushed in the lateral direction, the upper circumferential path 39 to the vertical path 3
Drive through the lower circumferential path 38 via 7. In this way, the downward movement as a composite component of the cam guide paths 20 and 27 is transmitted to the driven pin 14, and the pump device 3 is again returned to FIG.
The stored state shown in (a) is restored. Of course, even in this state, the driven pin 14 is constrained by the lower peripheral path 38 so as to be unable to move up and down, so that the pump device 3 is also held in a state where vertical movement (particularly upward movement) is blocked.

By the way, in order to prevent the driven pin 14 from slipping upward from the cam guide path 20 (upper circumferential path 39) when it is raised, the operating cylinder body 4 has a rotation operation amount within a predetermined range. The structure is restricted by. That is, as shown in FIG. 5B, a state in which the upper exit of the upper circumferential path 39 is blocked by a part of the pushing back surface 41 (the above-mentioned upper contact surface 42) in the cam guide path 27 is maintained. It is like this.

As shown in FIG. 7, this rotation amount limiting structure is provided with a stopper piece 45 hung vertically on the operating cylinder 4 so as to circumscribe the inner peripheral wall 23 of the operating cylinder 4, and at a predetermined time when the operating cylinder 4 is rotated. The stopper piece 45 comprises a butting piece 46 that is provided so as to project outward in the radial direction with respect to the mounting boss portion 16 of the plug base portion 2 so as to collide and interfere with the stopper piece 45 at a position (see FIG. 4). Reference numeral 47 is an engaging projection that holds the stopper piece 45 in contact with the butting piece 46 (that is, the usable state of the liquid container 6). The engagement protrusion 47 is capable of inducing a bending deformation in the vertical direction of the stopper piece 45 by applying a high operation force when the operation tube body 4 is rotated, and thereby overcoming it. .

In the present embodiment, the stopper base portion 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 also 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. As the pump device 3, for example, one having a structure as shown in FIG. 8 can be used. The piston rod 7a is hollow and communicates with the discharge port 3a of the elevating head 8, and the spring 50 is pressed and held between the lower part and the inner bottom part of the pump body 7. The spring pressing tool 51 is integrally connected. A plunger 54 is held around the spring pressing tool 51 so as to be vertically movable.

The spring pushing tool 51 is provided with upper and lower water passages 55 and 56 for communicating the inside of the piston rod 7a and the inside of the pump body 7, respectively.
The upper and lower water passages 55 and 56 are communicated with each other (see FIG. 8 (a)) or blocked (see FIG. 8 (b)) by the vertical movement of the spring pusher 51. ing. In the pump body 7, 57 is an air vent hole for smoothing the vertical movement of the plunger 54, and 58 is a check valve for preventing backflow of the contents.

In the pump device 3 having such a structure, when the elevating head 8 is pushed down, the plunger 54 descends via the piston rod 7a to increase the internal pressure of the container body 5 as shown in FIG. 8 (b). Therefore, the content in the container body 5 is pushed up and reaches the inside of the piston rod 7a from the lower water passage hole 56 through the upper water passage hole 55, and the discharge port 3
It will be discharged from a. When the pushing down operation of the elevating head 8 is released, the elevating head 8 is returned to ascend by the spring 50 as shown in FIG. In the raised state of the elevating head 8 as described above, the upper and lower water passages 55 and 56 are blocked by the plunger 54 as described above, so that the liquid container 6 is laid on its side or upside down. However, the contents in the container body 5 will not spill.

FIG. 9 shows a second embodiment of the plug device 1 according to the present invention. In the second embodiment, the operating cylinder 4 has a peripheral wall 23 of a single wall structure. This is different from the first embodiment (in the first embodiment, as shown in FIG. 3, the inner peripheral wall 23 and the outer peripheral wall 25 have a double wall structure). Since the other configurations, detailed structures, and operations are substantially the same as those in the first embodiment, those having the same operation will be denoted by the same reference numerals and detailed description thereof will be omitted.

The present invention is not limited to the above-described embodiments, and various detailed improvements and changes can be added. For example, in the interlocking means 10, by changing the lead angles of the cam guide paths 20 and 27 provided in the plug base portion 2 and the operation tube body 4 gradually, the rotational operation amount of the operation tube body 4, the operation torque, and the pump device 3 can be changed. Various lifting strokes can be changed.

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. The presence or absence of a structure for limiting the amount of rotational operation of the operating cylinder 4 or the structure itself can be appropriately changed. Also, the configuration itself of the pump device 3 can be replaced with various conventionally known structures.

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.

[0038]

According to the present invention, which has the above-described structure, the plug base is integrally provided with the container body, and the pump device is vertically movable with respect to the plug base. The operating cylinder is held so as to be rotatable around the stopper base. Normal state of liquid container (not in use)
In this case, the pump device is in the lowered state and is housed in the operating cylinder body. However, when the operating cylinder body is rotated in this state, the pump device rises in association with the operation of the interlocking means, and the pump device is installed in this pump device. The discharge port is exposed on the operating cylinder. Therefore, the pump device can be operated, and the liquid container is ready for use. On the other hand, when the operation cylinder is rotated in the opposite direction to the above, the pump device descends due to the reverse operation of the interlocking means, and the discharge port of the pump device is hidden below the operation cylinder again. Therefore, the pump device cannot be operated, and the liquid container is returned to the normal state (non-use state).

As described above, unlike the prior art, it is not necessary to screw out the outer lid each time the liquid container is used and screw it into the liquid container after use, so that the handling is very easy. Of course, there is no defect such as dropping the screwed outer lid to damage or lose it. In this way, the rotation of the operating cylinder causes the pump device to be taken in and out to switch whether the contents can be taken out or not. The switching state depends on whether the pump device is moving up or down. At first glance it becomes clear. Therefore, there is no risk of operating the pump device by mistake, and the waste of the contents can be saved. Further, even when the liquid container is dropped, the malfunction of the pump device can be prevented. In particular, as described above, it is extremely advantageous in that the pump device is prevented from malfunctioning when the liquid container is dropped, as it prevents failure of the pump device.

The structure of the interlocking means may be a cam structure in which a driven pin provided in the pump device and a cam guide path provided in the plug base and the operating cylinder so as to engage with the driven pin are combined. It is suitable. This cam structure is designed such that the direction of the turning force by the operating cylinder is synthetically converted to the vertical direction and then extracted as the vertical power for the pump device, which is structurally simple and has the advantage of excellent conversion efficiency. Have Therefore, the manufacturing cost can be reduced, the operation can be reliably performed, and the life can be extended.
