Description

The present invention relates to a cosmetic container.

Conventionally, a cosmetic holder containing cosmetics (cosmetics) is stored in a container so as to be movable in the axial direction, and a coil spring is provided between the cosmetic holder and the bottom of the container to bias the cosmetic holder forward. A cap that is removably attached to the container is provided with an applicator through a handle extending in the axial direction, and when the cap is attached to the container, the applicator enters into the container and removes the cosmetics stored in the cosmetic holder. The cosmetic holder is moved back in the axial direction against the biasing force of the coil spring while being in contact with and pressing down. On the other hand, when the cap is removed from the container, the cosmetic holder moves forward due to the biasing force of the coil spring, and the application part A cosmetic applicator is known that remains in contact with the cosmetic until it is separated from the applicator (for example, see Patent Document 1).

In this cosmetic applicator, when the cap is attached to the container, a space in contact with the cosmetic is formed between the cap and the cosmetic, and the cosmetic holder is moved between the cosmetic holder and the container. A moving gap (sliding gap) is formed to communicate with the space in contact with the cosmetic, and a moving space for the cosmetic holder to move back and forth between the cosmetic holder and the bottom of the container is formed in the moving gap. It is formed in a continuous manner.

Actual Publication No. 57-19045

In the above-mentioned cosmetic applicator, the space in contact with the cosmetics, the movement gap, and the movement space become the volatilization space where the cosmetics volatilize, so there is a problem that the volatilization space is large and the cosmetics dry quickly. In order to suppress this, it is desired to reduce the volatilization space.

Therefore, an object of the present invention is to provide a cosmetic container that can reduce the volatilization space.

The cosmetic container according to the present invention includes an inner container having a storage section that stores fluid cosmetic and allows the cosmetic to flow out from the opening, and an inner container that stores the inner container and allows the cosmetic that flows out from the opening to flow outside. The inner container includes an outer container having a hole that allows the water to flow out, and a valve that closes the hole by having a valve body at the tip seat on a valve seat provided around the hole. a cylindrical outer part whose bottom part is configured to be elastically deformable and stands up from the bottom; an inner part which stands inside the outer part in a cylindrical shape from the bottom and abuts against the valve in the movement direction of the valve; The accommodating part is formed between the inner circumferential surface of the outer part of the inner container, the outer circumferential surface of the inner part, and the bottom part, and the valve body is seated on the valve seat by an elastic body that comes into contact with the bottom part of the outer container. An elastic body is inserted into the cylindrical hole on the inner side, and the valve is in close contact with the inner side of the inner container over the entire circumference, and when the valve body of the valve is pressed, the valve It is characterized in that the inner part moves as the body moves, causing the bottom of the inner container to elastically deform, and a flow path is formed between the valve body and the valve seat to allow the cosmetic to flow out.

According to such a cosmetic container, when the valve body is pressed, the inner side of the inner container moves, the bottom of the inner container is elastically deformed, and the valve body is separated from the valve seat. The fluid can flow out of the flow path formed between the valve body and the valve seat. Here, the movement of the valve body from its seat is not caused by the movement of the entire inner container, but is performed by elastic deformation of the bottom of the inner container due to the movement of the inner part of the inner container. It is in close contact with the inner part of the inner container over the entire circumference. Therefore, there is no movement gap for the entire inner container to move, and the volatilization space is only the space from the valve body seated on the valve seat to the cosmetics stored in the storage part of the inner container, and the volatilization space is can be made smaller than before.

Here, the cosmetic is preferably a powder cosmetic. When the cosmetic is a powder cosmetic, the powder may remain attached to the bottom of the container containing the powder cosmetic and not come out even if the cosmetic container is turned upside down. As shown in the figure, when the valve body is pressed, the bottom of the inner container is elastically deformed, making it easier for powdered cosmetics adhering to the bottom of the inner container to come out.

In addition, if the bottom of the outer container is provided with a protrusion that abuts a part of the bottom of the inner container that is outside the inside part, the pressure of the valve body will cause the bottom part of the inner container to come into contact with the part that is inside of the part that abuts the protrusion. The portion can be easily elastically deformed in the direction of movement of the valve body.

Moreover, it is preferable that a valve is inserted into the cylindrical hole of the inner part, and that the outer circumferential surface of the valve is in close contact with the inner circumferential surface of the inner part of the inner container over the entire circumference. When such a configuration is adopted, when the pressure on the valve body is released, the valve body can be easily seated on the valve seat, and the valve body can be stably moved.

In addition, if the valve is provided with a plurality of protrusions extending laterally from the outer peripheral surface of the valve, the pressure of the valve body may cause the flow to flow out from the flow path formed between the valve body and the valve seat. The cosmetic can be suitably flowed out while being stirred by the plurality of protrusions provided on the outer peripheral surface of the bulb and extending laterally. Further, by repeatedly pressing and releasing the valve body to displace and seat the valve body on the valve seat, the cosmetic can be flowed out while being further agitated.

As described above, according to the present invention, the volatilization space can be reduced.

As shown in FIGS. 2, 3, 19, and 20, the puff 3 has a disc-shaped configuration, and a strap 47 is attached to the upper surface of the puff 3. This puff 3 is arranged between the covering part 28 of the stopper member 11 and the cap 2.

As shown in FIGS. 2 and 3, the cap 2 has a cylindrical shape with a cap, and the cap has a dome shape. A female screw 48 is formed on the inner circumferential surface of the cylindrical portion of the cap 2 and is screwed into the male screw 23 of the joint portion 10 .

Next, a procedure for assembling the cosmetic container 100 will be explained with reference to FIGS. 2 and 3.

First, the compression coil spring 8 is inserted into the cylindrical part 12 at the center of the base 9, and then the inner container 4 is inserted into the base 9, and the lower end surface of the flange part 16 of the outer part 33 of the inner container 4 is inserted into the outer part of the base 9. The inner container 4 is brought into contact with the upper end surface of the cylindrical portion 13 thereof, and the portion outside the outer peripheral edge a of the groove portion 38 of the bottom portion 35 of the inner container 4 is brought into contact with the protrusion 15 of the base 9. Then, a predetermined amount of cosmetic P is put into the accommodating portion 36 of the inner container 4.

Next, the joint part 10 is inserted and pushed into the outer cylindrical part 13 of the base 9, and the concave part 26 of the joint part 10 is fitted into the convex part 19 of the base 9 to be integrated, and the stepped part 22 of the joint part 10 and The flange 16 of the outer part 33 of the inner container 4 is sandwiched between the base 9 and the upper end surface of the outer cylindrical part 13. In this way, airtightness is achieved by sandwiching the flange 16 of the outer part 33 of the inner container 4 between the stepped part 22 of the joint part 10 and the upper end surface of the outer cylindrical part 13 of the base 9. .

Next, the lower cylindrical part 45 of the valve 7 is inserted and pushed into the cylindrical hole of the inner part 34 of the inner container 4, and the lower end surface of the upper cylindrical part 44 is brought into contact with the upper end surface of the inner part 34 of the inner container 4. The convex portion 46 of the lower cylindrical portion 45 is fitted into the concave portion 41 of the inner side portion 34 of the inner container 4 to be integrated. In this way, by fitting the convex part 46 of the lower cylindrical part 45 of the valve 7 and the recess 41 of the inner part 34 of the inner container 4, the lower cylindrical part 45 of the valve 7 can be inserted into the inner part of the inner container 4. The portion 34 is in close contact with the entire circumference and is airtight.

Next, the plug member 11 is inserted and pushed into the joint portion, and the convex portion 32 of the cylindrical portion 27 of the plug member 11 is fitted into the recess portion 24 of the joint portion 10 to be integrated. In this way, by fitting the convex part 32 of the cylindrical part 27 of the plug member 11 and the concave part 24 of the joint part 10, airtightness is achieved.

In this state, the lower end surface of the lower cylindrical portion 45 of the valve 7 comes into contact with the compression coil spring 8 and is urged upward, and the O-ring 18 of the valve body 29 of the valve 7 is pressed against the valve seat 30 of the plug member 11. It is in a seated state. FIG. 4 shows this state. In this way, the valve element 29 (including the O-ring 18) of the valve 7 and the valve seat 30 of the plug member 11 are in close contact with each other to ensure airtightness.

Next, the puff 3 is placed on the covering part 28 of the stopper member 11, the female screw 48 of the cap 2 is screwed into the male screw 23 of the joint part 10, and the cap 2 is tightened to form the structure shown in FIGS. 1 and 2. A cosmetic container 100 is obtained. In this state, as shown in FIG. 2, the puff 3 is sandwiched between the dome-shaped covering part 28 of the stopper member 11 and the dome-shaped crested part of the cap 2, and is deformed to follow the dome shape. There is. Further, the O-ring 25 of the joint portion 10 and the inner circumferential surface of the cylindrical portion of the cap 2 are in close contact with each other to ensure airtightness.

In such a cosmetic container 100, when the cap 2 shown in FIG. The space up to the cosmetic P accommodated in the part 36, more specifically, the space between the cylindrical part 27 of the plug member 11, the covering part 28 of the plug member 11, and the space below the covering part 28 of the plug member 11 in the valve 7. It is defined between the exposed portion and the cosmetic P of the inner container 4. Note that even in the state shown in FIG. 4 in which the cap 2 and puff 3 are removed from the container body 1, the volatilization space S is the same space as in FIG. 2.

Next, an example of how to use the cosmetic container 100 will be described with reference to FIGS. 2 and 5.

First, the cap 2 shown in FIG. 2 is removed from the container body 1, and the fingers F, such as the middle finger and index finger, are inserted into the strap 47 of the puff 3 (see FIG. 5) and the puff 3 is taken out.

Next, as shown in FIG. 5, the container body 1 is turned upside down. Then, the cosmetic P moves (falls) toward the valve body 29 as shown by the arrow, but since the valve body 29 closes the hole 5 (see Figure 2), the cosmetic P flows out to the outside. do not.

In this state, the puff 3 is pressed against the valve body 29 as shown by the arrow. Then, in the inner container 4, as shown in FIG. The contacting portion b is used as a point of effort, and the end c of the base 9 on the bottom 14 side of the inner portion 34 is used as a point of action, and the bottom portion 35 is elastically deformed on the principle of leverage (see FIG. 5). Specifically, the inner part 34 moves toward the bottom part 14 side of the base 9, and uses the edge a on the outer circumferential side of the groove part 38 of the bottom part 35 as a fulcrum, and moves the inner part from the edge a of the bottom part 35, that is, the bottom part 35. In this case, a portion of the base 9 on the inner side of the contact portion with respect to the projection 15 is curved toward the bottom portion 14 of the base 9 .

Further, as shown in FIG. 5, as the inner part 34 moves toward the bottom 14 of the base 9, the curvature of the part of the bottom 35 inside the part of the base 9 that is in contact with the protrusion 15 becomes larger, and the bottom part 35 becomes more curved. A bottom surface 50 (see also FIG. 10) of the groove (recess) 38 contacts the tip 51 of the protrusion 15 on the bottom 14 of the base 9. Then, using the portion d of the bottom surface 50 that contacts the tip 51 of the bottom portion 14 of the base 9 as a fulcrum, the inner portion of the portion d that contacts the portion d further curves toward the bottom portion 14 of the base 9 , and the base 50 at the inner portion 34 The end c, which is the point of action on the bottom 14 side, is close to the bottom 14 of the base 9.

In this state, since the valve body 29 is separated from the valve seat 30, a flow path R is formed between the valve body 29 and the valve seat 30, which allows the cosmetic P to flow out. be done. Cosmetic material P can flow out through this flow path R and be attached to the puff 3, and the user can apply the puff 3 to which the cosmetic material P has adhered to the area to be coated.

Here, when the cosmetic P flows out, the cosmetic P is suitably flowed out while being stirred by the plurality of protrusions 42 provided on the outer peripheral surface of the valve 7 and extending laterally. Then, by repeatedly pressing and releasing the valve body 29 and causing the valve body 29 to leave and sit on the valve seat 30, a desired amount of the cosmetic P can be deposited on the puff 3.

After use, the user returns the container body 1 from upside down to the original state shown in FIG. Then, the cap 2 is attached to the container body 1 to form the cosmetic container 100 shown in FIGS. 1 and 2.

Thus, in this embodiment, when the valve body 29 is pressed, the inner side 34 of the inner container 4 moves, the bottom part 35 of the inner container 4 is elastically deformed, and the valve body 29 is separated from the valve seat 30. Therefore, the cosmetic P in the inner container 4 can flow out from the flow path R formed between the valve body 29 and the valve seat 30.

Particularly in this embodiment, the movement of the valve body 29 from its seat is not due to the movement of the entire inner container, but is due to the elastic deformation of the bottom portion 35 of the inner container 4 due to the movement of the inner portion 34 of the inner container 4. Since the valve 7 having the valve body 29 is in close contact with the inner side 34 of the inner container 4 over the entire circumference, there is no movement gap for the entire inner container to move, and the volatilization space S is There is only a space from the valve body 29 seated on the seat 30 to the cosmetic P accommodated in the accommodating portion 36 of the inner container 4, and the volatilization space can be made smaller than before.

Here, when it comes to powdered cosmetics, even if the cosmetics container is turned upside down, the powdered cosmetics may remain attached to the bottom of the container containing the powdered cosmetics and not come out, but as mentioned above, When the valve body 29 is pressed, the bottom portion 14 of the inner container 4 is elastically deformed, so that powder cosmetics adhering to the bottom portion 14 of the inner container 4 can easily come out.

Further, in this embodiment, since the bottom 14 of the outer container 9 is provided with the protrusion 15 that comes into contact with a portion outside the inner side 34 of the bottom 35 of the inner container 4, the pressure of the valve body 29 allows the contents to be removed. The part of the bottom 35 of the container 4 that is inside the part that contacts the protrusion 15 can be easily elastically deformed in the moving direction of the valve body 29 (downward in FIG. 2; toward the bottom 14 of the base 9).

Further, in this embodiment, the valve body 29 is biased in the direction of seating on the valve seat 30 by the compression coil spring 8 that comes into contact with the bottom part 14 of the outer container 9, and the valve body 29 is provided in the cylindrical hole of the inner part 34. Since the compression coil spring 8 is inserted and the outer circumferential surface of the valve 7 is in close contact with the inner circumferential surface of the inner part 34 of the inner container 4 over the entire circumference, when the pressure on the valve body 29 is released, the valve body 29 is released. The valve body 29 can be easily seated on the valve seat 30, and the valve body 29 can be moved stably.

Furthermore, in this embodiment, the valve 7 is provided with a plurality of protrusions 42 extending laterally from the outer circumferential surface of the valve 7, so that the pressure of the valve body 29 causes the valve body 29 and the valve seat 30 to be connected to each other. Cosmetic material P that is about to flow out from the flow path R formed between them can be suitably flowed out while being stirred by the plurality of protrusions 42. Further, by repeatedly pressing and releasing the valve body 29 to displace and seat the valve body 29 on the valve seat 30, the cosmetic P can be flowed out while being further stirred.

Although the present invention has been specifically described above based on the embodiments thereof, the present invention is not limited to the above embodiments. For example, in the above embodiments, the base 9 and the joint portion 10 connect the inner container 4. Although the flange portion 16 is sandwiched between the joint portions 10, the joint portion 10 may be connected to the base 9 without sandwiching the flange portion 16. In this case, the inner container 4 may be fixed to the base 9 side by fitting the engaging portion or the like.

Further, in the above embodiment, the outer circumferential surface of the lower cylindrical portion 45 of the valve 7 is brought into close contact with the inner circumferential surface of the inner portion 34, but the diameter of the upper portion of the inner portion 34 is reduced and the lower portion of the valve 7 is The diameter of the cylindrical portion 45 of the valve 7 is expanded, and the structure is changed so that the cylindrical portion 45 of the lower part of the valve 7 is fitted onto the upper part of the inner part 34, and the cylindrical part 45 of the lower part of the valve 7 is attached to the outer peripheral surface of the upper part of the inner part 34. The inner peripheral surface of the portion 45 may be in close contact with each other. In this case, it is preferable that the compression coil spring 8 be in contact with the lower end surface of the upper part of the inner part 34 whose diameter has been reduced.

Further, in the above embodiment, an annular groove 38 is provided in the bottom surface of the bottom 35 of the inner container 4 in order to facilitate elastic deformation, but the groove 38 may not be provided. In this case, when the valve body 29 is pressed, the bottom 35 of the inner container 4 is elastically deformed toward the bottom 14 of the base 9 using the portion of the bottom 35 that is in contact with the tip 51 of the protrusion 15 of the base 9 as a fulcrum. I will do it. Note that it is sufficient that the bottom portion 35 of the inner container 4 can be elastically deformed by the pressure of the valve body 29.

Further, in the above embodiment, the valve body 29 of the valve 7 has the O-ring 18 and is airtight with the O-ring 18, but only the valve body 29 is seated on the valve seat 30 of the plug member 11 to ensure airtightness. If it can be removed, the O-ring 18 may be omitted.

Further, in the above embodiment, the cosmetic container 100 houses the puff 3, but the present invention can also be applied to a cosmetic container without the puff 3.
