Description

[Detailed Description of the Invention] The present invention relates to a liquid cosmetic container suitable for containing liquid cosmetics such as mascara, liquid eyeliner, and liquid lipstick.

BACKGROUND ART Conventionally, containers for storing liquid cosmetics such as mascara and liquid eyeliner have been known to have a structure in which a squeeze stopper is provided inside and a brush barrel is squeezed by the squeeze stopper.

In this type of container, when the brush barrel is pulled out of the container, the squeezing stopper works to scrub off excess liquid cosmetics adhering to the brush barrel and the applicator brush at its tip, reducing the amount of cosmetics adhered to the brush barrel. It can be made into a uniform and constant amount.

By the way, there are generally individual differences in the amount of liquid cosmetics (hereinafter referred to as cosmetics) used; for example, people who want to emphasize their eyes more with mascara etc. use more, while people who want a natural finish use less. The amount used is small.

In such cases, with conventional containers with a built-in ironing stopper, the amount of cosmetics that adheres to the applicator brush is uniform and constant, as described above, so the amount of applied cosmetics can be adjusted as necessary. Therefore, people who want to use a lot of lotion have to put the applicator brush in and out of the container many times, while people who only use a small amount have to use the iron stopper. There were some problems, such as having to use it after squeezing it several times.

The present invention was created in consideration of the above points, and it is possible to steplessly adjust the amount of cosmetic liquid applied to the applicator brush to match the amount of cosmetic liquid required by the user. To provide a liquid cosmetic container which is extremely easy to operate and whose adjustment function works reliably.

The present invention will be explained below based on an embodiment shown in FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a container body, and 2 denotes a lid body having a brush shaft 4 with an applicator brush 3 that can be inserted into and taken out from the container body 1 freely.

In this embodiment, the container body 1 is composed of a bottomed cylindrical outer container 5 and an inner container 6 that is fixedly fitted into the outer container 5 and substantially contains the cosmetic liquid A. There is.

The outer circumferential diameter of the inner container 6 is approximately the same as the inner circumferential diameter of the outer container 5, and the length of the inner container 6 is such that the opening peripheral wall 6a of the inner container 6 is located above the opening of the outer container 5. It is formed longer than the outer container 5 so as to protrude toward the outer container 5.

Furthermore, inside the mouth peripheral wall 6a of the middle container 6, there is an annular projection 7 that projects radially inward from the inner wall surface of the middle container 6, and a small diameter part that extends upward (towards the lid 2) from the annular projection 7. A cylindrical portion 8 is integrally provided, and the brush shaft 4 is guided into the medium container 6 through this small diameter cylindrical portion 8.

On the outer circumferential side of the small diameter cylindrical portion 8, an ironing stopper 9 having a headed cylindrical shape and having a thread 9a on the outer circumferential surface is fitted by a rotation prevention mechanism so as to be slidable only in the axial direction of the small diameter cylindrical portion 8. There is.

The ironing stopper 9 has a circular ironing hole 9b in its head, through which the brush shaft 4 passes, and is made of a material having appropriate elasticity such as rubber as a whole.

As shown in FIG. 2, the rotation prevention mechanism of the ironing plug 9 includes a guide groove 8a formed on the outer peripheral surface of the small-diameter cylindrical portion 8 and extending in the axial direction of the cylindrical portion 8, and a guide groove 8a of the ironing plug 9. A guide rib 9 provided on the inner circumferential surface and fitted into the guide i8a.
It is composed of c.

Note that these guide grooves 8a and guide ribs 9C may be reversed.

In the inner container 6 of the container body 1, a cylindrical operating member 10 having a female thread 10a on the inner circumferential surface which is screwed into the male thread 9a of the ironing stopper 9 is rotated around the axis of the container body 1 by a removal prevention mechanism. It is fitted so that it can rotate freely.

The mechanism for preventing the operation member 10 from being removed is a mechanism for preventing the operation member 10 from being removed.
An annular convex portion 10b provided on the lower outer periphery of the inner container 6, and an annular concave portion 6b formed on the inner circumferential surface of the mouth peripheral wall 6a of the inner container 6 into which the convex portion 10b fits.

Note that the removal/stopping mechanism may also be reversed.

The operating member 10 has the inner container 6 at its longitudinally central portion.
The outer cylinder 11 has a large diameter portion 10c having an outer diameter substantially the same as that of the outer container 5, and an outer cylinder 11 having an outer diameter substantially the same as the outer diameter of the outer container 5 is fixed to the outer peripheral side of the large diameter portion 10c.

This outer cylinder 11 has a length dimension that allows the inner container 6 to cover the entire outer circumferential surface of the portion of the outer container 5 that protrudes from the mouth edge of the outer container 5, that is, the portion of the mouth edge peripheral wall 6a of the inner container 6. The inner diameter of the outer cylinder 11 is set so that it can rotate together with the operating member 10.

Also, of the inner circumferential surface of the operating member 10, at least a portion corresponding to the range from the normal position of the ironing plug 9 (the position shown by the solid line in the figure) to the sliding limit position (the position shown by the chain line in the figure) The inner circumferential surface is formed into a tapered surface 10e whose inner diameter gradually becomes smaller than the outer diameter of the ironing stopper 9 toward the sliding limit position side (lid body 2 side).

A male thread 10d is provided on the outer peripheral surface of the upper part of the operating member 10, and a male thread 10d is provided on the inner peripheral surface of the middle cylinder 2a of the lid body 2.
A female screw 2b is provided which is screwed into the hole d.

In the figure, 4a is a small diameter portion formed for the purpose of preventing interference between the brush shaft 4 and the straining hole 9b when the lid body 2 is in the closed position, and 12 is a gasket.

The operation of the liquid cosmetic container configured in this way will be explained below.

As shown in FIG. 1, when the lid body 2 is closed and the ironing plug 9 is in the fixed position shown by the solid line, the ironing plug 9 is kept in its original shape, and the inner diameter of the ironing hole 9b changes. There isn't.

Here, when the operating member 10 is rotated through the outer cylinder 11, the ironing stopper 9 is slidable only in the axial direction by the rotation prevention mechanism consisting of the guide groove 8a and the guide rib 9c. 9a and the female screw 10a, it slides upward.

When the ironing stopper 9 slides upward, the ironing stopper 9 is gradually elastically deformed inward by the action of the tapered surface 10e during the sliding process, and at the sliding limit position of the ironing stopper 9 is shown by the chain line in the figure. It transforms like this.

Therefore, the inner diameter of the straining hole 9b also becomes smaller.

Note that when the operating member 10 is rotated in the opposite direction, the ironing stopper 9 descends and returns to its home position, returning to its original shape.

As can be understood from the above operation, if the operating member 10 is rotated appropriately, the inner diameter of the straining hole 9b changes depending on the amount of rotation.

Therefore, the application brush 3 that is squeezed through the squeezing hole 9b
The adhesion of the cosmetic liquid can be adjusted steplessly by determining the amount of rotation of the operating member 10.

Further, this adjustment can be performed by simply rotating the operating member 10.

Furthermore, the ironing plug 9 slides due to the action of the male thread 9a and the female thread 10a that are screwed together, so that it operates reliably.

FIG. 3 shows another embodiment of the present invention, in which the ironing stopper 9 is composed of a lower member 13 and an upper member 14, and the lower member 13 is made of a material having appropriate hardness. The upper member 14 is made of plastic, and the upper member 14 is made of an elastic material such as rubber, and the lower half of the inner container 6 is cut out and a fixed lower ironing stopper 15 made of an elastic material is provided in this part. This embodiment differs from the previous embodiment in that the outer diameter of the large diameter portion 10c of the operating member 10 is made equal to the outer diameter of the outer container 5, so that the outer peripheral surface of the large diameter portion 10c is directly exposed.

The operation and effect of this embodiment are almost the same as those of the embodiment shown in FIG.
3 and an upper member 14, and the lower member 13 is made of a material with appropriate hardness, so the male thread 9a and the female thread 10a are well screwed together, and therefore the ironing stopper 9 can easily slide. This has the advantage of smoother movement.

Furthermore, the lower squeezing stopper 15 allows excess lotion adhering to the brush shaft 4 and applicator brush 3 to be squeezed off in advance.

As described in detail above, according to the present invention, the amount of cosmetic liquid applied to the applicator brush can be adjusted steplessly to match the amount of cosmetic liquid required by the user, and the adjustment operation is extremely easy. It has the excellent effect of being simple and its adjustment function working reliably.
