Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a restricting device which is mounted on a screw portion of a discharge nozzle of a pump container for storing a liquid material such as a shampoo or a rinse and restricts a discharge amount of contents.

[0002]

2. Description of the Related Art Conventionally, pump-type containers have been widely used as containers for shampoos, rinses, liquid soaps and the like used in bathrooms at home. The container is
A pump mechanism is provided from the center of the cap to the inside of the container, and a discharging nozzle is disposed above the cap, and the contents are discharged by pushing down the discharging nozzle with a palm. The depressing stroke is about 15 to 18 mm with a value of 700 cc or more.
The discharge amount is about 3 cc.

[0003]

However, the above discharge amount is a predetermined amount by the manufacturer, and whether or not the discharge amount is optimal depends on the condition of each user. For example, in the case of a shampoo, the amount is too large if the user is a child or a person with little hair, and the amount is too small if the user is heavily soiled or has a lot of hair. If the amount is too large, the shampoo cannot be returned to the container, so the shampoo must be used as it is, and the contents are wasted. Furthermore, even when rinsing, a large amount of water is used, which is a waste of water.

[0004] If the pushing-down stroke of the dispensing nozzle is adjusted so as to stop at an intermediate position, an amount of less than 3 cc can be dispensed. However, it is difficult to adjust the force, and the desired amount can be dispensed. Did not. In particular, it was almost impossible if the user was a young child.

[0005] The present invention has been made in view of the above problems, and reduces the discharge amount of the contents of the pump container by about 1 /.
Reducing the volume to 2/3 reduces waste of contents and water, and also limits the discharge amount of the pump container, which makes it easy to pinch even when used by children and enhances the willingness to clean the appearance. The purpose is to provide tools.

[0006]

In order to solve the above-mentioned problems, in the discharge amount limiting device for a pump container according to the present invention, two fulcrum portions of two sandwiching pieces like a washing sandwicher are fitted and a spring is engaged. Then, the two sandwiching pieces are integrated. A clamping portion is formed on the tip side of the two clamping pieces, and a push-off piece is disposed on the other end side. Further, a screw groove of the same size as the screw pitch of the screw portion of the ejection nozzle is formed in the holding portion of the two holding pieces, or an appropriate elasticity and friction such that the screw portion of the ejection nozzle is engaged. A strong elastic material is provided.

The discharge amount restricting device 1 for a pump container according to the present invention fits a fulcrum 3 of two sandwiching pieces 2 and 2 ′ like a washing pinch, and engages a spring 6 to connect the two clamping pieces 2. 2 'is integrated. In FIG. 1, the fulcrum 3 (not shown) of the holding piece 2 is convex, the fulcrum 3 of the holding piece 2 ′ is concave, and each support 3 has a hole 7 for inserting a pin 8. There is. Then, insert the pin 8 into the hole 7
The two sandwiching pieces 2, 2 'are integrated. Although two springs 6 are used in FIG. 1, any number may be used as long as appropriate strength is obtained. In addition, the fulcrum 3 may be fitted by any method such as simply combining the convex fulcrum and the concave fulcrum without using the pins 8 and fitting them.

[0008] A clamping portion 4 is formed at the tip end of the two clamping pieces 2 and 2 ', and a push-off piece 5 is disposed at the other end of the two clamping pieces 2 and 2'. Set up. In FIG. 1, the opposing sandwiching portions 4 are linear and rectangular, but may be rounded. The push-off piece 5 has a large disk shape so that even a child can easily push open the discharge amount limiting tool 1 and pinch it to the pump container 11. If a character or the like that a child likes is drawn on the surface of the pushing piece 5, it will look cute. The shape and size of the pushing piece 5 and the contents to be drawn on the pushing piece 5 may be arbitrary. Further, a three-dimensional structure may be used.

FIG. 2 is a sectional view taken along the line A--A in FIG. 1, in which a screwing groove having the same thread pitch as that of the screw portion of the ejection nozzle is formed in the clamping portion. By reliably screwing the discharge amount restricting tool 1 with the screw portion 14, the discharge amount restricting tool 1 does not wobble. The screwing groove 9 may be formed in the same manner as the material of the sandwiching pieces 2 and 2 ', or may be provided so as to embed a metal fitting.

FIG. 3 is a cross-sectional view taken along the line A--A in FIG. 1, in which an elastic material is disposed at the clamping portion. Since the elastic material 10 has appropriate elasticity and frictional force, the ejection nozzle 15 is provided.
The discharge amount restricting tool 1 does not wobble by engaging the screw portion 14 of FIG. As the elastic material 10, soft rubber or soft resin is preferable.

[0011]

An embodiment of the present invention will be described with reference to the drawings. FIG.
FIG. 3 is a view showing a state before the discharge amount restricting device of the pump container of the present invention is inserted into the pump container and a procedure for inserting the same. FIG.
In this case, the downward stroke of the ejection nozzle 15 is L1, and is generally about 15 to 18 mm. Here, in order to clamp the discharge amount restricting tool 1 to the pump container 11, the push-off piece 5 of the discharge amount restricting tool 1 is pushed to open the distal end portions of the clamping pieces 2 and 2 '. Since the diameter of the screw portion 14 of the ejection nozzle 15 is thicker than the stem 13 and it is difficult to pinch the screw portion 14 as it is, the screw portion 14 of the holding pieces 2 and 2 ′ is passed through the stem 13 and pulled up. The discharge amount restricting tool 1 is clamped between the screw portions 14.

FIG. 5 is a view showing a state after the discharge amount restricting device of the pump container according to the present invention is clamped to the pump container. In FIG. 5, the width of the discharge amount restricting tool 1 is set to L3, and the pushing stroke is limited by the width.
L2 obtained by subtracting L3 is the extrusion stroke in this case. In the threaded portion 14 of the ejection nozzle 15, the threaded portion 1 at the base of the ejection nozzle 15 opposite to the stem 13.
No. 4 cannot be completely inserted into the cap 12 and has a space of about 4 mm. For this reason, if the width L3 of the discharge amount restricting tool 1 is set to about 12 mm, L2 becomes about 7 to 10 mm, and the discharge amount of the pump container 11 can be limited to about 1/2 in FIG. In addition, by adjusting the holding position of the discharge amount restricting tool 1 while shifting it, it is possible to limit to about 1/3.

If the discharge amount restricting device 1 of the present invention is sandwiched between the pump container 11 as described above,
If the limit value is set to about 1/2 for a pump container 11 of a value-type pump container 11 of cc or more, the content of about 1.5 cc is discharged by pushing down the discharge nozzle 15 once for a small amount of use. be able to. In addition, the content of about 3 cc can be discharged by pushing down the discharge nozzle 15 twice for normal use, and the discharge nozzle 15 is used for a large amount of use.
By pushing down three times, the contents of about 4.5 cc can be discharged.

[0014]

As described above, the following effects can be obtained by clamping the discharge amount restrictor of the pump container of the present invention to the screw portion of the discharge nozzle of the pump container. Since the discharge amount of the contents of the pump container can be reduced from about 1/2 to 1/3, for example, in the case of shampoo, even a small amount of people such as a child or a person with little hair can pour without waste. it can. Since the used amount of the contents becomes an appropriate amount, the amount of water used for rinsing or the like can be reduced. Since the pushing piece is made large, even a child can easily pinch and adjust, and drawing a character or the like which a child likes on the pushing piece is also cute in appearance, so that the motivation to wash can be increased. .
