Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a compact container for storing a liquid cosmetic, in which a liquid cosmetic such as a cream foundation and a puff are housed in one container.

``Prior Art'' Compact containers are generally used to store solid foundations among various cosmetic products, and are often used for simple makeup touch-ups on the go.

By the way, even when you are out and about, depending on the situation, you may need a cream foundation in addition to a solid foundation. By the way, conventional compact containers do not have a structure in which the container body is completely sealed even when the lid is closed, so it is difficult to store low-viscosity cosmetics such as cream foundation inside. It was impossible to contain them directly. Therefore, if you want to use the cream foundation on the go, you have to put it in a bottle or tube container and carry it around with the compact container, which makes it unusable. Also, cream foundations stored in containers such as bottles are much more difficult to use than solid foundations stored in compact containers in terms of opening and closing the lid and taking out the cosmetics. There was a drawback.

Therefore, recently, compact containers designed to store liquid cosmetics such as cream foundations in a bag have been developed, for example, in Utility Model Application No. 57-33013 (Utility Model Application No. 61-38501). issue)
is provided by. This compact container is the first
As shown in Figure 0, a lid 2 is attached to a container body 1, a bag (not shown) containing a liquid cosmetic is housed in the container body 1, and a push plate 3 is attached to the top of the bag. The frame body 4 is attached to the container body 1 with the container body 1 placed thereon. A puff holder 3a is formed in the push plate 3, and a discharge port 4a for the liquid cosmetic is formed in the frame 4. The lid 2 also includes a gasket 2a that closes the discharge port 4a when the container body 1 is closed by the lid 2.
is installed.

``The problem that the invention attempts to solve'' However, with the compact container mentioned above,
Although it has the advantage of being able to store the puff and liquid cosmetic in one container, it has the following problems in use.

That is, when using this compact container, first, the liquid cosmetic is pushed out from the discharge port 4a by pressing the puff holder 3a, and then,
A puff is taken out from the puff holder 3a, and the liquid cosmetic material discharged from the discharge port 4a is soaked into the puff.

For this reason, when extruding liquid cosmetics, an excess amount may be discharged due to momentum etc.
Even when cosmetics are not used, the puff container may be pressed inadvertently and the cosmetics may be discharged from the outlet, resulting in the cosmetics in the bag being wasted. It was hot. Furthermore, as the cosmetics inside the bag are consumed, the bag deflates and the positions of the push plate 3 and the puff holder 3a are lowered, which impairs the appearance of the surrounding area. There were problems such as it became difficult to put in and take out the puff, making it less convenient to use.

"Means for Solving the Problems" The present invention provides a compact container for effectively solving the above-mentioned problems, in which a liquid cosmetic is stored in a liquid cosmetic storage chamber of the container body. A flat box-shaped storage container for storing the bag body is attached so as to be slidable back and forth along the bottom surface of the storage chamber, and a pump mechanism for discharging liquid cosmetics is provided to the bag body, and a pump mechanism is provided on the top surface of the storage container. A discharge port for the liquid cosmetic is formed, and the pump mechanism further moves up and down at least a part of the bottom plate of the storage container when the storage container slides between the bottom plate of the storage container and the bottom plate of the storage chamber. The device is characterized by being provided with an operating mechanism for operating the.

"Operation" When the storage container is pressed laterally against the compact container for storing liquid cosmetics having the above structure and the storage container is slid along the bottom surface of the storage chamber, the bottom plate of the storage container and the bottom surface of the storage chamber are brought into contact with each other. An operating mechanism provided between the two bags works together to push up the bottom plate of the storage container, which activates the pump mechanism and discharges the liquid cosmetics inside the bag from the outlet.

"Example" The first embodiment of the present invention will be described below in Figures 1 to 6.
To explain with reference to the figures, in these figures,
The reference numeral 5 is a container body, the reference numeral 6 is a partition, the reference numeral 7 is a bag for storing the liquid cosmetic stored in the container main body 5, and the reference numeral 8 is a storage container for storing the bag 7.

Next, to explain these specifically,
As shown in FIG. 3, the container main body 5 has a storage chamber S therein for storing the storage container 8, and is formed as a whole in the shape of a saucer with a desired cross-sectional shape (for example, rectangular shape). . The container body 5 is hinged to a lid (not shown) via a pin or the like at the rear wall thereof so as to be freely openable and closable.

The inner partition 6 is fixedly arranged on the upper surface of the container main body 5, and on one side of the upper surface of the inner partition 6 is an insertion opening 9 for inserting the storage container 8 into the storage chamber S of the container main body 1. is formed. Also,
On the other side of the upper surface of the inner partition 6 is a storage chamber S in the container body 1.
A window 10 is formed to expose the upper surface of the storage container 8 inserted into the inner partition 6.
A notch 11 that opens into the insertion port 9 is formed in the central portion 6a.

The bag body 7 is formed of a synthetic resin such as polyethylene into a flat bag shape having an opening on the top surface, and a pump mechanism 12 for discharging the cosmetics in the bag body 7 is installed in this opening. It is being

The storage container 8 is formed into a flat box shape as a whole, and includes an upper lid 14 having a recess 13 that opens downward and holds the bag 7 inside, and an upper lid that contacts the lower surface of the bag 7. 14, and a lower lid 15 that is fitted into the recess 13 so as to be vertically movable. In this configuration, a liquid cosmetic discharge port 16 is formed on the upper surface of the upper lid 14, and locking protrusions 17 are protruded from the lower end of the inner surface of the recess 13 of the upper lid 14. Lid 1
Locking protrusions 17 and 17 are provided at the upper end of the outer surface of the side part of
Locking protrusions 18 and 18 are provided in a protruding manner to engage with.

Between the bottom plate of the storage container 8 (bottom plate of the lower lid 14) and the bottom surface of the storage chamber S is an operating mechanism 19 that operates the pump mechanism 12 by vertically moving the bottom plate of the storage container (bottom plate of the lower lid 14). The operation mechanism 19 has a convex portion 19a projecting from the lower surface of the lower lid 15 of the storage container 8, and a surface formed on the bottom surface of the storage chamber S and sloped in the sliding direction of the storage container 8. It is composed of a convex portion storage recess 19b.
The pump mechanism 12 operated by the operating mechanism 18 has a cylinder 20 as shown in FIG.
It is mainly composed of a piston 21 that is movable up and down in close contact with the inner wall surface of the cylinder 20, and an elastic member 22 that urges the piston 21 downward.

A first flow path 23 is formed at the center of the upper end of the cylinder 20, passing through the discharge port 16 of the upper lid 14 and the cylinder interior 20a, and a circumferential protrusion 24 is provided protruding from the inner periphery of the lower end of the cylinder 20. has been done. An annular recess 20b is formed around the upper end opening of the first flow passage 23.
An outer valve 25 having a valve body 25a that opens the first flow passage 23 when the hydraulic pressure inside the cylinder 20a exceeds a set pressure is attached to the outer valve b. This outer valve 25
The opening of the cylinder 20, that is, the first flow passage 23, is always kept in a closed state by the elastic force of the valve body 25a itself, and the hydraulic pressure inside the cylinder 20a is controlled according to the design of the pump mechanism 13. When a set pressure greater than the discharge pressure is exceeded, the fluid pressure opens the first flow passage 23 against the elastic force of the valve body 25a.

A second flow path 26 is formed at the center of the upper end of the piston 21, and the second flow path 26 passes through the cylinder interior 20a and the piston interior 21a.
A piston interior 21 is provided on the lower end side wall of the piston 21.
A and the bag body 7 are connected to each other, and a flow path 27 is formed which opens and closes according to the vertical movement of the piston 21. Further, on the outer periphery of the upper end of the piston 21, a circumferential protrusion 27 that engages with the circumferential protrusion 24 of the cylinder 20 is formed. 28 is provided protrudingly. Further, an annular recess 21b is formed around the upper end opening of the second flow passage 26, and the second flow passage 26 is opened in this annular recess 21b when the hydraulic pressure inside the cylinder 20a is below a set pressure. Valve body 29
An inner valve 29 having a shape is attached to the ring. This inner valve 29 always keeps the opening of the piston 21, that is, the second flow passage 26, in a closed state by the elastic force of the valve body 29a itself, and when the piston moves downward, the inner valve 29 keeps the opening of the piston 21, that is, the second flow passage 26, closed. The second flow passage 26 is set to be opened by negative pressure against the elastic force of the valve body 29a. Note that the configurations of the outer valve 25 and the inner valve 29 are not limited to those of this embodiment, and may have other configurations.

Furthermore, although a coil spring is used as the elastic member 22 in the embodiment, it may be of any other configuration as long as it urges the piston 21 downward.

Next, the method of use and operation of the compact container of this embodiment configured as described above will be explained.

In this compact container, a bag 7 containing a liquid cosmetic such as a cream foundation is stored in a storage container 8, and the storage container 8 is inserted into the container body 5 through an insertion opening 9 under a storage pressure S. It is used after being inserted into the desired position. When using this, first open the bag (not shown), and then open the notch 1 of the inner partition 6.
1 and press the storage container 8 sideways (direction A in the figure), as shown in FIG.
The lower lid 15 is pushed up while the protrusion 19a on the lower surface of the container main body 5 comes into contact with the inclined surface of the protrusion storage recess 19b on the bottom of the container body 5, and thereby the piston 21 is also pushed up. Then, as shown in Figure 6,
The flow passage 27 between the piston interior 21a and the bag body 7 is closed, and the cylinder interior 20a is pressurized. As a result, the outer valve 25 disposed in the first flow passage 23 opens, and the cylinder interior 20a is closed. The liquid cosmetic is discharged from the discharge port 16 of the upper lid 14. At this time, the piston 21 closes the flow path 27, thereby preventing the cosmetic from flowing back into the bag body 7.
Therefore, the amount of cosmetic material discharged onto the upper lid 14 is a constant amount (that is, the amount accumulated in the cylinder interior 20a below the first flow path 23).

Once the cosmetics in the bag body 7 have been discharged in this way, the puff can be soaked with the cosmetics and then used. In addition, if the amount of makeup dispensed with one pressing operation is insufficient, press the storage container 8 sideways (direction A in the figure) again as necessary, and then let it soak into the puff. Just use it.

The piston 21 once pushed up returns to its original state as shown in FIG. 7 due to the repulsive force of the resilient member (coil spring) 22 that urges the piston 21 downward, and When the outer valve 25 is closed and the pressure inside the cylinder 20a is reduced, the inner valve 29 disposed in the second flow path 26 opens, and the cosmetic inside the piston 21a flows into the cylinder inside 20a. . Then, the flow path 27 between the inside of the piston 21a and the bag body 7 is opened, and the pressure inside the piston 21a is reduced, so that the liquid cosmetic in the bag body 7 is transferred to the inside of the piston 21a.
flows into. At this time, the cosmetic in the bag 7 flows into the piston interior 21a, so the bag 7 deflates by that amount and is ready for the next pressing operation.

FIG. 8 shows a second embodiment of the present invention, in which a lower lid 15 is fixed to the upper lid 14 of the storage container 8, and the bottom of the lower lid 15 is made thin enough to be flexible. be. In this embodiment, the partition 6 is not provided, and grooves 30 and 30 are provided in the inner wall of the storage chamber S of the container body 5 along the pressing direction (direction A) as shown in FIG. Protrusions 31 and 31 that engage with the grooves 30 and 30 are provided on the outer surface of the side wall of the upper lid 15.
By providing slits 32 and 32 on both sides of the projections 31 and 31 so that the container 8 can be easily inserted into the storage chamber S from above, the storage container 8 can be easily inserted into the storage chamber S.
I try to keep it that way. Note that the length of the groove 30 may be set to the sum of the length of the protrusion 31 and the sliding distance of the storage container 8. According to this embodiment, when the storage container 8 is slid in the direction A, the bottom of the lower lid 15 bends and pushes up the piston 21 of the pump mechanism 12, so that the same effect as in the first embodiment can be obtained. .

Note that the same effects as in the first embodiment can also be obtained by forming the bottom of the lower lid 15 with a flexible slit structure.

"Effects of the invention" As explained above, according to the invention, by sliding the storage container laterally, a certain amount of liquid cosmetics inside the bag can be discharged.
Afterwards, you can use the dispensed cosmetic by simply dipping it into the puff. Therefore, the compact container is very easy to use and operate. Moreover,
Since there is no need to worry about discharging an excess amount of cosmetics from the discharge port, cosmetics will not be wasted and the cosmetics in the bag can be used efficiently. Furthermore, since the bag body is stored in the storage container, the cosmetics will not be discharged even if the storage container is pressed carelessly, and even if the bag body deflates due to consumption of cosmetics, the container will not close. It has no effect on appearance. Moreover, excellent effects such as easy exchange of the bag can be achieved.
