Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a constant-quantity dispensing container capable of quantitatively dispensing contents such as cosmetic cream from the inside of the container body.

"Prior Art" Conventionally, as this kind of constant-volume discharge container, there is, for example, a structure as shown in Figs. In this fixed-quantity discharge container, a lid 2 is hinged to a wall of a container body 1 having an upper surface opening 1a, and a cartridge body 3 containing a liquid content is housed inside the container body 1. In addition, a liquid passage hole 4 is formed on the upper surface of the cartridge body 3 for discharging the liquid content onto the upper surface of the cartridge body 3 when the cartridge body 3 is pushed down. Cartridge body 3
Is provided with an elastic body 5 for urging up and down.

When this fixed-quantity discharge container is used, if the lid 2 is opened and the upper surface of the cartridge body 3 is pushed down, the liquid level of the liquid content inside the cartridge body 3 rises relatively and the liquid passage hole 4
Since the liquid content is discharged from above to the upper surface of the cartridge body 3, the discharged liquid content is soaked into the puff P and the like.

“Problems to be solved by the invention” However, in the above-mentioned conventional fixed-quantity discharge container, as described above, by pushing down the cartridge body 3 to relatively raise the liquid level of the liquid content inside the cartridge body 3, The liquid content passes through the liquid passage hole 4 to the cartridge body 3
Since it is configured to discharge on the upper surface of, the amount of discharge has to be adjusted by adjusting the pressure of fingers and the like, and adjustment of the amount of discharge is troublesome. Further, since the liquid level lowers as the liquid content is consumed, it is necessary to push down the upper surface of the cartridge body 3 in this case, and the cartridge body 3 itself is accompanied by a decrease in the volume of the content. Since it does not shrink, there is a drawback that the liquid tightness gradually decreases and the dischargeability of the liquid content gradually deteriorates. Further, according to this conventional example, when the content in the cartridge body 3 becomes zero, the cartridge body 3 itself is replaced. However, the liquid content can be easily added to the cartridge body 3 without replacing the cartridge body 3. If it can be filled in, it is beneficial from the economical point of view.

The present invention has been made in view of the above circumstances, and a fixed-quantity discharge container capable of easily and reliably discharging a fixed amount of liquid content from the container body, and moreover, easily filling and storing the liquid content in the container body.

The configurations of 3 and the inner valve 37 are not limited to those of this embodiment, and may be other configurations.

The recess 14 of the container body 10 and the pressing piece 23 of the case body 12 together form an operating mechanism 38 for operating the pump mechanism 27. Further, as the elastic member 30, a coil spring is applied in the embodiment, but any other structure may be used as long as it biases the piston 29 downward.

Next, the method of use and the operation of the constant-volume discharge container of the present embodiment configured as described above will be described.

This fixed-quantity discharge container, as the liquid content in the bag body 13,
For example, a liquid cosmetic material such as a cream foundation is stored, and the upper end portion of the pump mechanism 27 of the bag body 13 is fitted to the discharge port 18 of the movable plate 16 and the bag body 13 is held.
Is placed in the case body 12, and the case body 12
Will be stored and arranged at the intended position in the storage chamber 10a of the container body 10 for use.

When using this fixed-quantity discharge container, first, the lid 11 is opened, and as shown in FIG. 2, the movable plate 16 of the case body 12 is slid laterally (direction A in the figure) with a fingertip or the like. When it is dynamically operated, the pressing piece 23 of the bottom lid 17 rides on the inclined surface from the concave portion 14 of the storage chamber 10a and is pushed up, whereby the piston 29 is also pushed up. Then, as shown in FIG. 5, the flow path 3 between the inside 29a of the piston and the bag body 13 is
5 is closed and the inside 28a of the cylinder is pressurized. As a result, the outer valve 33 disposed in the first flow passage 31 is opened, and the liquid cosmetic inside the inside 28a of the cylinder is moved to the movable plate 1.
6 is discharged from the discharge port 18. At this time, the cylinder 28 closes the flow path 35, which prevents the cosmetic material from flowing back into the bag body 13. Therefore, the amount of the cosmetic material discharged onto the movable plate 16 is constant (that is, the amount accumulated in the cylinder interior 28a below the first flow passage 31).

After the cosmetic material is discharged into the bag body 13 in this manner, the puff P may be soaked with the cosmetic material and used. In addition,
When the amount of cosmetics discharged by one sliding operation is insufficient, the movable plate 16 is again slid laterally as necessary to allow the discharged cosmetics to soak into the puff P for use. do it.

The piston 29 that has been pushed up once is
Repulsive member (coil spring) 30 for urging 9 downward
6 returns to the original state shown in FIG. 6, and at this time, the outer valve 33 is closed and the cylinder interior 28a is depressurized, so that the second flow passage 3
4, the inner valve 37 provided at 4 opens and the piston inside 29
The liquid cosmetic of a flows into the cylinder interior 28a. Then, the flow path 35 between the piston inside 29a and the bag body 13 is opened and the piston inside 29a is depressurized, so that the liquid cosmetic material inside the bag body 13 flows into the piston inside 29a. At this time, the cosmetic material in the bag body 13 flows into the piston inside 29a, so that the bag body 13 is deflated by that amount, and the preparation for the next sliding operation is completed.

According to this embodiment, the pump mechanism 27 is mounted on the tubular plug body 26 that is provided in a liquid-tight manner with respect to the bag body 13, so that the filling port for the liquid cosmetic material can be increased and the bag body 1
Liquid cosmetics can be easily filled and housed in 3. Further, by mounting the pump mechanisms 27 having different discharge performances in the form of cartridges on the mouth plugs 26 provided in the bag body 13, it is possible to widen the range of application of the constant volume discharge container. Since only the type is required, it leads to a reduction in manufacturing cost.

FIG. 9 is a diagram showing a second embodiment of the present invention, in which the liquid content in the bag body 13 is discharged from the discharge port 18 to the upper surface of the movable plate 16 by pressing the movable plate 16 downward. It was done like this. As shown in the figure, the container body 1
At the center of the bottom surface inside 0, a convex portion 39 that abuts the lower surface of the piston 29 and lifts the case body 12 upward with a gap S ′ from the bottom surface is provided in a protruding manner. The case body 12 is configured only by the movable plate 16 that is vertically movable in a state of being in close contact with the inner wall surface of the container body 10. And
On the inner wall surface of the container body 10, a locking projection 40 is provided so as to prevent the movable plate 16 from coming off upward, and on the outer wall surface of the movable plate 16, the projection 4 that engages with the locking projection 40.
1 is projected.

According to this embodiment, since the liquid content is discharged by the downward pressing operation, the discharging operation becomes easier.
Moreover, since the number of parts of the case body 12 is small, the manufacturing cost can be further reduced.

[Advantage of Invention] As described in detail above, according to this invention, by operating the movable plate, it is possible to easily and reliably discharge a certain amount of the liquid content in the bag body. Since it is not necessary to adjust the amount by pressing the fingers, etc., it is very convenient. Also, when consuming liquid contents,
Since the bag body also squeezes as the liquid content decreases, the liquid tightness does not always decrease, and the liquid content can be efficiently discharged to the end due to the action of the pump mechanism.
Furthermore, when the liquid content in the bag becomes zero, the liquid content can be easily filled and stored in the bag simply by removing the pump mechanism from the plug body that is liquid-tight with respect to the bag. . Further, this allows the bag to be used repeatedly without replacement, which is advantageous from the economical point of view. Furthermore, if pump mechanisms having different discharge performances are attached to the mouth plugs in the form of cartridges, the range of use can be expanded, and other excellent effects can be obtained. Moreover, at the time of manufacturing this container, the quality (function) of the pump mechanism itself can be checked before the pump mechanism is attached to the plug body, so that the pump mechanism alone can be inconvenient. Even if there is, only the pump mechanism needs to be replaced. On the other hand, if the pump mechanism is not removable, the function of the pump mechanism cannot be checked until the container is assembled, and if there is a problem, the entire container becomes a defective product. . Thus, in the container of the present invention,
Even if there is a problem with the pump mechanism, it is easy to deal with it, and the cost of defective products can be reduced.
