Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a stopper for a dispenser used for a natural spray, a pump and the like.

2. Description of the Related Art Dispensers used for natural sprays, pumps, etc. have been widely known. This type of dispenser has a plug body fitted and fixed to a container body for shampoo, rinse, cosmetic liquid, etc., and a push button fitted in this plug body. A fixed amount chamber is provided in the stopper body, and a piston is slidably accommodated in the fixed amount chamber.
The hollow piston shaft is slidably held by the plug and protrudes upward, and the push button is fitted to the piston shaft.

Therefore, when this push button is pushed down, the piston moves by a certain distance, which pressurizes the metering chamber,
The liquid in the metering chamber is discharged to the outside through the hollow hole of the piston shaft from the discharge port of the push button by a fixed amount.

However, in the above dispenser, if the push button is pressed by mistake during transportation, storage, etc., the liquid in the metering chamber will be inadvertently discharged. As a device to prevent such a situation, the cover is covered from the upper surface of the lid to the outer periphery of the pressing to prevent malfunction of the dispenser and protection from external impact.
The inventions disclosed in Japanese Utility Model Publication No. 60-41340 and Japanese Utility Model Publication No. 63-144464 are known.

In addition, it is possible to adjust the discharge amount of the content liquid,
There is a device described in Japanese Utility Model Laid-Open No. 63-131953. In this invention, a restriction piece for adjusting the movement stroke of the piston shaft is fitted to the piston shaft.

However, the devices described in Japanese Utility Model Publication Nos. 59-126956, 60-41340, and 63-144464 have a push button depression amount, that is, a stroke of movement of a piston shaft. Is fixed, a fixed amount of liquid is ejected each time the push button is pressed. Therefore, there is an inconvenience that it is impossible to discharge a desired amount of the user or an appropriate amount of contents according to the place of use, for example, by discharging a liquid amount more than the amount required by the user.

Further, the device disclosed in Japanese Utility Model Laid-Open No. 63-131953 cannot prevent malfunction and protect from external impact even though the discharge amount can be adjusted.

The present invention was made in order to solve the above-mentioned conventional problems, and one of the purposes is to connect a conventionally known dispenser and to supply an appropriate amount of contents according to the user's preference and use location. Is to be able to discharge.

Another object of the present invention is to prevent malfunction of the dispenser and protect it from external impact when the dispenser is not used, transported, or stored. Then, these two purposes are to be made possible by a single cover provided detachably on the dispenser.

Means for Solving the Problems In order to solve the above problems, the present invention has a stopper body slidably holding a piston shaft of a piston disposed in a metering chamber, and a piston body fitted to press the piston shaft. In a dispenser consisting of a push button that is operated and discharges the contents corresponding to the movement amount of the piston from the fixed quantity chamber to the outside, the piston shaft of this dispenser is slidably inserted to make a stopper. The outer periphery of the cover is detachably covered, and on the side surface in the axial direction, a covering body is formed in which a split groove through which the piston shaft can be inserted is formed up to the top plate, and the axial diameter of this covering body is set to the maximum protruding state of the piston shaft. The push button with the piston shaft inserted to the bottom dead center between the lower end of the push button and the upper end surface of the cover attached to the stopper, and the piston shaft is inserted to the bottom dead center. And And the plug body can be covered and stored.

Operation In the above-mentioned structure, when the dispenser is operated to discharge the contents, when the maximum amount of liquid is to be discharged, the piston shaft should be inserted to the bottom dead center without using the stopper of the present invention. For example, the maximum amount of liquid in the metering chamber is discharged from the push button.

Further, in order to adjust the discharge liquid amount, the piston shaft is slidably inserted to removably cover the outer periphery of the plug body. In this state, a lowering interval of the push button is formed between the lower end of the push button and the upper end surface of the cover, and the lowering of the push button is possible only with this lowering interval. This descending interval is naturally smaller than the amount of movement of the piston shaft to the bottom dead center, and the push button and the piston shaft move by this descending interval, and the discharge amount can be reduced.

Therefore, the user can adjust the desired amount of liquid by lowering the piston shaft without using the coating according to the intended content amount or by removing the coating from the outer periphery of the stopper. It can be taken out accurately.

Also, when the dispenser is not used, transported, stored, etc., the cover is removed from the piston shaft, the piston shaft is lowered to the bottom dead center and fixed, and the cover is attached to the stopper from the top surface. By covering the outer circumference, malfunction of the dispenser can be prevented and protection from external impact can be achieved.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(1) is a stopper, which is airtightly fitted and fixed to the mouth and neck of a container (2) containing contents such as shampoo, rinse, and cosmetic liquid, and a fixed quantity chamber (not shown) is provided therein. A piston (not shown) is slidably accommodated in the fixed amount chamber.

Then, one end of a hollow piston shaft (3) is fixed to this piston, and the other end of the piston shaft (3) is slidably upward from the holding cylinder (4) of the plug body (1). A screwing portion (not shown) is provided which can be biased and protruded and which can fix the position when it is inserted into the fixed amount chamber up to the bottom dead center.

In addition, the split groove (6) is formed from the upper end surface of the top plate (5) to the axial side surface.
Is provided to form the covering (7). Then, the outer periphery of the plug body (1) is detachably coated with the coating body (7), and the piston shaft (3) is slidably inserted into the split groove (6) in the maximum protruding state.

Further, when the piston shaft (3) is in the maximum protruding state, the plug body (1) is
When the covering body (7) is attached to the upper part of the piston shaft (3), the lower end of the push button (8) is fixed between the lower end of the push button (8) fixed to the upper end of the piston shaft (3) and the upper end surface of the covering body (7). ), The axial diameter of the covering (7) is determined. Further, this axial diameter is the push button (8) and the plug body (1) in the state where the piston shaft (3) is inserted into the plug body (1) up to the bottom dead center.
Is long enough to cover and store.

When the dispenser is actuated to discharge the contents in the structure as described above, when the maximum amount of liquid is to be discharged, the piston (7) which is the stopper of the present invention is not used, and the piston is used. When the shaft (3) is inserted to the bottom dead center, the maximum amount of the content in the metering chamber is discharged from the push button (8).

Further, in order to adjust the discharge liquid amount, the piston shaft (3) in the maximum discharge state is slidably inserted into the split groove (6) of the covering body (7) to remove the stopper body (1). The outer periphery is removably coated with a coating (7). In this state, the lowering interval (10) of the push button (8) is formed between the lower end of the push button (8) and the upper end surface of the cover (7).

Then, the push button (8) can be lowered only during the lowering interval (10), but the lowering interval (10) is equal to the piston shaft (3).
The amount of movement up to the bottom dead center is naturally less than this, and only the lowering interval (10) corresponds to the push button (8) and piston shaft (3).
Can be moved, and the discharge amount can be reduced. Therefore,
The user selects the covering body (7) according to the intended amount of contents.
It is possible to accurately take out a desired amount of liquid by lowering the piston shaft (3) with or without.

When the dispenser is not used, transported, stored, etc., the cover (7) is removed from the piston shaft (3) and the piston shaft (3) is lowered to the bottom dead center and fixed.
By covering the outer circumference of the stopper with the cover from the upper surface of the push button (8), malfunction of the dispenser can be prevented and protection from external impact can be achieved.

Effect of the Invention Since the present invention is configured as described above, the content amount can be adjusted and discharged according to the user's preference and use location, and the content can be effectively utilized without waste.

When not in use, remove the cover from the piston shaft,
It can be used as a cap and can prevent malfunction of the dispenser and protect from external impact.

In addition, the above-mentioned technical effect is made possible by a single cover provided detachably on the dispenser, and an economical and inexpensive product can be obtained.
