DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispenser, and more particularly to a dispenser for discharging a content containing granules in a liquid.

[0002]

2. Description of the Related Art For example, some emulsion or lotion containers are provided with a dispenser for discharging the contents by pressing a push button provided on the head. According to the dispenser-equipped container, it is not necessary to tilt the container to take out the contents, so that the container is easy to handle, and a fixed amount of contents can be taken out every time by operating the push button.

FIGS. 5 to 8 show a conventional dispenser 10.
FIG. 3 is a diagram for explaining the configuration of FIG. FIG. 5 is a cross-sectional view for explaining the overall configuration of the dispenser 10. still,
In the figure, the left part of the center line shows a state in which a pressing operation is performed to discharge the contents (hereinafter, referred to as an operation state), and the right part of the center line shows a state in which the pressing operation is released (hereinafter, referred to as an operation state). Operation release state).

In FIG. 1, 1 is a stem, 2 is a cylinder, 3 is a coil spring, 4 is a cap, and 8 is a piston. The stem 1 is a cylindrical nozzle pipe 5
And a cylindrical piston guide 6 having a bottom. The piston guide 6 is mounted on the cylinder 2 so as to be movable in the axial direction of the cylinder 2 (directions indicated by arrows X1 and X2 in the figure). Further, a cap 4 is fixed to an upper portion of the cylinder 2, and the dispenser 10 is fixed to the container by attaching the cap 4 to a container (not shown).
The coil spring 3 is mounted inside the cylinder 2, and the above-mentioned stem 1 is disposed so as to be located above the coil spring 3. Therefore, the stem 1 is always urged in the direction of the arrow X2 by the elastic force of the coil spring 3.

[0005] The piston 8 is arranged on the outer periphery of the piston guide 6 constituting the stem 1. This piston 8
Is located between the inner circumference of the cylinder 2 and the outer circumference of the piston guide 6 in the mounted state, and has a function of defining the both liquid-tight. Further, the piston 8 is configured to be slidable on the inner periphery of the cylinder 2, so that even if the stem 1 moves in the directions of the arrows X1 and X2 with respect to the cylinder 2, the stem 1
And the cylinder 2 are maintained in a liquid-tight state.

A valve housing 17 is formed at the lowermost end of the cylinder 2, specifically, below the position where the coil spring 3 is provided, and a ball valve 9 is provided in the valve housing 17. It is arranged. The ball valve 9 is a check valve that allows only the contents loaded in the container to advance into the cylinder 2. Therefore, when the contents in the container enter the cylinder 2, the ball valve 9 moves upward in the valve housing portion 17. However, in order to restrict the upward movement more than necessary, as shown in FIG. A restriction piece 18 formed in a spiral shape is formed on the reference numeral 3 so that the diameter dimension gradually decreases. The upward movement of the ball valve 9 is restricted by contacting the restricting piece 18, thereby preventing the ball valve 9 from functioning as a check valve that has penetrated deeply into the cylinder 2.

Here, FIG. 6 shows the stem 1 in an enlarged manner, and FIG. 7 shows the piston guide 6 in an enlarged manner. The structure of the stem 1 will be described in further detail. As described above, the stem 1 is constituted by the nozzle pipe 5 and the piston guide 6, and the piston guide 6 located at the lower part is fixed so as to be fitted inside the nozzle pipe 5 located at the upper part.

The piston guide 6 has a bottomed cylindrical shape having a bottom portion 13 at the lower end of a cylindrical portion 16. Tubular part 1
6, a hole 15 is formed, and the hole 15 is opened by the piston 8 in the operating state.
Further, it is configured to be closed in the operation release state. Further, a skirt portion 12 extending downward (in the direction of the arrow X1 shown in FIG. 5) is formed at an outer peripheral position of the bottom portion 13. The upper end of the coil spring 3 is engaged with the skirt portion 12, and an opening 14 is formed on a side portion.

Next, in the dispenser having the above-mentioned structure, the stem 1 is moved from the operation release state shown on the right side of the center line in FIG. 5 (assuming that the contents are sucked and filled in the cylinder 2). The operation of each component when is pressed will be described. When the stem 1 is pressed and moved in the direction of arrow X1 in the figure against the elastic force of the coil spring 3, a space 19 formed by the cylinder 2 and the bottom 13 of the stem 1 (contents are contained in this space). Is smaller).

For this reason, as shown by the arrow in the figure, the contents in the space 19 are formed by the opening 1 formed in the skirt 12.
4, the hole 15 formed in the cylindrical portion 16 (as described above,
In the operating state, the piston 8 advances through the hole 15) into the stem 1. Then, the contents move upward in the nozzle pipe 5 of the stem 1, and a discharge port 20 formed at the upper end of the nozzle pipe 5 (the discharge port 20 is provided with a normal injection nozzle or the like). ). At this time, the ball valve 9 prevents the contents in the space 19 from flowing back into the container.

On the other hand, when the pressing operation is released, the stem 1 is moved by an arrow X2 in FIG.
, And the volume of the space 19 increases accordingly. After the operation state, there is no (or little) content in the space 19, and the hole 15 formed in the cylindrical portion 16 is closed by the piston 8. Therefore, as the volume of the space 19 increases as described above, a negative pressure is generated in the space 19.

Therefore, the ball valve 9 is opened by moving upward, and the contents in the container are sucked into the cylinder 2.
As a result, the space 19 described above is filled with the contents, and is ready for the next discharge operation.

The stem 21 has a configuration in which a cylindrical nozzle pipe 25 and a bottomed cylindrical piston guide 26 are integrated, and is movable in the axial direction of the cylinder 22 (directions indicated by arrows X1 and X2 in the figure). It is mounted on the cylinder 22 with a simple configuration. The nozzle pipe 25 and the piston guide 26 are both resin molded products, and are integrated using a fixing method such as bonding or press fitting.

A cap 2 is provided above the cylinder 22.
The dispenser 20 is fixed to the container 27 (indicated by a dashed line) by attaching the cap 24 to the container opening.
For this reason, a screw portion 31 is formed on the inner peripheral portion of the cap 24, and the screw portion 31 is screwed to a screw portion (not shown) formed at the container opening of the container 27. I have.

The container 27 is loaded with a cosmetic (eg, serum, cream, etc.) in which a granular drug is mixed into a liquid cosmetic. This granular drug has, for example, a cigar shape having a diameter of φ0.6 mm and a length of 1.25 mm. The coil spring 23 is formed of an elastic metal selected so as not to deteriorate the contents, and is mounted inside the cylinder 22. The stem 21 is disposed so as to be located above the coil spring 23, and therefore, the stem 21 is
It is configured to be constantly urged in the direction of being pulled out from the cylinder 22 (the direction of the arrow X2).

The piston 28 is an annular member formed of, for example, silicone rubber or resin, and
Are arranged so as to surround the outer periphery of the piston guide 26 constituting the above. A large diameter portion 39 is formed below the piston guide 26, and a step 38 is formed at a fixed position between the piston guide 26 and the nozzle pipe 25. The piston 28 has a large diameter portion 39 and a step portion 38.
In this configuration, the piston guide 26 can be moved up and down by a small amount in the vertical direction (the directions of arrows X1 and X2 in the figure).

The piston 28 is located between the inner circumference of the cylinder 22 and the outer circumference of the piston guide 6 when the stem 21 is mounted on the cylinder 22.
2 has a function of defining liquid-tight. Also, the piston 28
Is configured to be slidable on the inner periphery of the cylinder 22,
Therefore, the stem 21 is moved with respect to the cylinder 22 by arrows X1, X2.
Even if the stem 21 moves in the direction, the stem 21 and the cylinder 22 are maintained in a liquid-tight state.

A valve housing 37 is formed at the lowermost end of the cylinder 22 (specifically, below the position where the coil spring 23 is provided), and a ball valve 29 is provided in the valve housing 37. Are arranged. This ball valve 29
In a state in which the discharge operation is not performed (hereinafter, referred to as an operation release state), the suction passage 44 that abuts the valve seat 43 provided in the cylinder 22 by its own weight and suctions the contents is closed.

However, as will be described later, the stem 21,
Space 45 formed by cylinder 22 and piston 28
When the internal pressure becomes negative, the ball valve 29 moves upward in the valve storage portion 37, and the contents in the container 27 are transferred from the suction passage 44 to the space portion 4.
5. Allow to proceed within 5. That is, the ball valve 29
Functions as a check valve that allows only the progress of the contents from the container 27 toward the cylinder 22.

As described above, when the contents in the container 27 enters the cylinder 22, the ball valve 29 is moved to the valve housing 37.
However, if it moves up to the inside of the cylinder 22 beyond the range of the valve housing portion 37, the function as the check valve may not be sufficiently performed. For this reason, in order to restrict the upward movement of the ball valve 29 more than necessary, a restriction piece 41 is formed on the coil spring 23 as shown in FIG.

In this embodiment, the regulating piece 41 is formed by bending the end of the coil spring 23 inward. Thereby, as shown in FIG. 4A, the restricting piece 41 is configured to extend in the radial direction when the coil spring 23 is viewed in a plan view, and thus the upward movement of the ball valve 29 is restricted by the restricting piece 41. can do.

The coil spring 23 of this embodiment is
A regulating piece 41 is provided at both the upper end and the lower end.
This is to avoid assembling the dispenser 20 in consideration of the up and down of the coil spring 23 when assembling the dispenser 20, thereby improving the assemblability. Here, referring to FIG. 2 and FIG.
Further, the configuration of the piston guide 26 will be described in more detail.
As described above, the stem 21 is constituted by the nozzle pipe 25 and the piston guide 26. The nozzle pipe 25 is a cylindrical member, and a discharge nozzle (not shown) for discharging contents is attached to a discharge port 46 formed at an upper end thereof. The discharge nozzle also functions as a button for pressing the stem 21.

The piston guide 26 has a bottomed tubular shape having a bottom portion 33 at the lower end of the tubular portion 36. Also,
A hole 35 is formed in the cylindrical portion 36.
5 is configured to be opened in the operation state and closed in the state in which the operation is released (hereinafter, referred to as an operation released state) due to the displacement between the step portion 38 and the large diameter portion 39 of the piston 28 described above. Have been.

In this embodiment, the shape of the above-mentioned hole 35 is rectangular, and is formed larger than the conventional hole 15 (see FIG. 7). Specifically, the maximum width dimension L1 of the hole 35 is larger than the maximum width dimension L2 of the granules (L2 <L
1) It is set to be. The maximum width dimension L1 is the length of the diagonal line of the hole 35 when the shape of the hole 35 is rectangular as in the present embodiment. Further, since the size and shape of the granules are known in advance, setting the maximum width dimension L1 of the hole 35 as described above can be easily performed.

The maximum width dimension L1 of the hole 35 is set to be smaller than the radial distance L3 of the piston guide 26 (see FIG. 2B) (L1 <L3). This is because if the hole 35 is set too large, the strength of the piston guide 26 may be reduced, and the operation of the stem 21 may not be performed smoothly. Also, the piston guide 26
At the outer peripheral position of the bottom portion 33, there is a downward (arrow X1 shown in FIG. 1).
(A direction)). The upper end of the coil spring 3 is configured to urge the stem 21 in the arrow X2 direction by engaging with the skirt portion 32.

An opening 34 is formed on the side of the skirt portion 32. In the present embodiment, the upper edge 34a of the opening portion 34 formed in the skirt portion 32 and the bottom surface 33a of the bottom portion 33 constituting the piston guide 26 are configured to be flush (see FIG. 2B). ). Next, the operation of the dispenser 20 configured as described above will be described mainly with reference to FIG. In the following description, each configuration when the stem 21 is pressed from the operation release state (assuming that the contents are sucked and filled in the cylinder 22) shown on the right side of the center line. Will be described.

When the discharge nozzle provided at the discharge port of the nozzle pipe 25 is pressed and the stem 21 moves in the direction of arrow X1 in the drawing against the elastic force of the coil spring 23, the stem 21 (bottom portion 33), The volume of the space 45 (containing the contents in this portion) formed by the cylinder 22 and the piston 28 is reduced. Therefore, as shown by arrows in the figure, the contents in the space 45 are filled with the suction passage 44, the opening 34 formed in the skirt 32, and the cylindrical portion 3.
6 through the hole 35 (the piston 28 opens the hole 35 in the operating state as described above) into the stem 21.

Then, the contents move upward in the nozzle pipe 25 of the stem 21, and the discharge port 4 of the nozzle pipe 25
The liquid is discharged to the outside from the discharge nozzle 6 through a discharge nozzle. In the operating state, the ball valve 29 prevents the contents in the space 45 from flowing back into the container 27. As described above, at the time of the discharging operation, the contents including the granules advance into the inside of the stem 21 through the suction passage 44, the opening 34, and the hole 35. At this time, the content that has entered the cylinder 22 from the suction passage 44 first passes through the position where the coil spring 23 is provided.

As described above, the coil spring 23 is formed with the regulating piece 41 located in the passage of the contents. However, the regulating piece 41 according to the present embodiment is formed by bending the end of the coil spring 23 inwardly as described above. Therefore, the passage area of the contents at the upper and lower ends of the coil spring 23 is widened, and even if granules are mixed in the contents, the granules can be surely passed without being clogged with the regulating piece 41. Can be.

The contents having passed through the coil spring 23 subsequently pass through the opening 34. As described above, the opening 34 of this embodiment is configured such that the upper edge 34 a thereof is flush with the bottom surface 33 a of the bottom portion 33. Therefore,
Compared to a conventional configuration in which the bottom portion 13 is located at a position facing the opening portion 14 (see FIGS. 6 and 7), the substantial area of the opening portion 34 through which the contents flow is increased, and thus granules are mixed. Even if the contents are the same, the granules can surely pass through the opening 34, and thus the opening 34 can be prevented from being clogged with the granules.

The contents having passed through the opening 34 subsequently pass through the hole 35. As described above, the hole 35 has a rectangular shape, and its size is set to be larger than that of the conventional hole 15. Further, the maximum width dimension L1 of the hole 35 is set to be larger than the maximum width dimension L2 of the granules (L2 <L1). Therefore, even if the content is a mixture of granules, the granules can reliably pass through the holes 35, thereby preventing the holes 35 from being clogged with granules.

In this embodiment, the shape of the hole 35 is a rectangle having short sides in the directions of arrows X1 and X2 and long sides in the circumferential direction, as described above. This is because the piston 28 is opened and closed by a minute displacement of the piston 28. Therefore, if the length in the directions of the arrows X1 and X2 is increased, it becomes difficult for the piston 28 to open and close the hole 35 accurately.

In the structure of this embodiment, the length of the short side of the hole 35 may be smaller than the maximum width L2 of the granule. However, according to the experiment of the present inventor, it has been proved that the granules pass through the holes 35 smoothly by forming a portion larger than the maximum width dimension L2 of the granules in a part of the holes 35. Was. On the other hand, when the pressing operation is released, the stem 21 moves in the arrow X2 direction in the figure due to the elastic restoring force of the coil spring 23, and the volume of the space 45 increases accordingly. After the end of the operation state, there is no (or little) content in the space 45, and the hole 35 formed in the cylindrical portion 36 is
8 is closed.

As a result, as described above, the volume of the space portion 45 is increased, so that the inside of the space portion 45 becomes a negative pressure, the ball valve 29 is opened by moving upward, and the contents in the container are transferred to the cylinder 22. Is sucked into. As a result, the space 45 described above is filled with the contents, and is ready for the next ejection operation.

[0046]

According to the present invention as described above, the following various effects can be realized. According to the first aspect of the present invention, it is possible to maintain the strength of the tubular member, and to reliably pass the contents containing the granules through the hole. Further, according to the second aspect of the present invention, since the opening is not substantially narrowed by the bottom portion, even the content in which granules are mixed can be surely passed through the opening. .

Further, according to the third aspect of the present invention, the unnecessary movement of the ball valve can be restricted, and the contents containing granules can be surely passed through the restriction piece. .
