Description

The present invention relates to a coating container equipped with an applicator for applying a content liquid.

2. Description of the Related Art Application containers equipped with a brush-like or brush-like applicator as shown in Patent Document 1, for example, are known as containers for storing liquids such as nail polish, lip gloss, mascara, eyeliner, and the like. Such applicator containers have an applicator at the tip of the shaft and a cap with an applicator that is attached to the container containing the liquid content, so it is not necessary to use a separate applicator when applying the liquid content. There is no need to prepare anything and it is very convenient. Furthermore, by attaching the cap with applicator to the mouth part, the liquid content can be attached to the applicator, so the cap with applicator can be removed and the liquid can be applied immediately. On the inside of the mouth part, there is provided a straining part whose diameter decreases downward and through which the shaft part is inserted when the applicator-equipped cap is attached to the mouth part. The tip of the squeezing part is in elastic contact with the periphery of the shaft when the cap with applicator is attached to the mouth, so when the cap with applicator is removed, the tip of the squeezing part can be removed from the shank or around the applicator. The content liquid can be scraped off with the tip of the squeezing part.

Japanese Patent Application Publication No. 2010-88516

In a dispensing container equipped with a squeezing part in this way, by removing the cap with the applicator, it is possible to scrape off excess liquid that has adhered to the shaft or around the applicator; Since the liquid is not scraped off, the liquid may remain in the form of icicles at the tip of the applicator. For this reason, it may be necessary to scrape off the excess liquid by rubbing the tip of the applicator against a squeezing member or wipe it off with a tissue paper or the like before applying the liquid to the destination.

It is an object of the present invention to solve these problems, and the present invention provides an applicator in which the excess liquid adhering to the tip of the applicator can be scraped off by removing the cap with the applicator. The purpose is to provide a container.

The present invention is a coating container comprising a container that stores a liquid inside a mouth opening at the top, and a cap with an applicator that has an applicator at the tip of a shaft and is attached to the mouth. , the container includes a container body having the mouth and a storage space for the liquid content, an elastically deformable partition wall provided inside the mouth part and convex upward, and a slit penetrating the partition wall. When the cap with applicator is attached to the mouth, the slit opens to allow the shaft to pass through, and when the cap with applicator is removed from the mouth, the slit closes. A slit valve is provided at the lower end of the applicator, and a tip applicator is provided at the lower end of the applicator and tapers downward from above, and the applicator protrudes radially outward from the lower end of the partition wall, which is circular in top view. A mating protrusion is provided, and the engaging protrusion is hooked from below on the lower end of the mouth within the container, and extends from the portion of the partition wall where the engaging protrusion is provided coaxially with the partition wall . A cylindrical portion extending downward is provided with respect to the mating projection , and when the applicator is pulled up and the partition wall comes into contact with the tip application portion, the partition wall has an upwardly convex shape. When restored, the coating container has a portion formed at the central tip of the partition wall to bend downward along the outer circumferential surface of the tip application section and come into contact with the outer circumferential surface.

The container is provided inside the mouth part and is capable of scraping off the content liquid adhering to the applicator, and has a strainer through which the shaft part is inserted when the cap with the applicator is attached to the mouth part. Equipped with a cylindrical part,
It is preferable that the slit valve is provided closer to the housing space than the squeezing cylinder part.

It is preferable that the applicator includes a brush portion configured with a plurality of protrusions that protrude in a direction away from the axis of the shaft portion, and the tip applicator is provided below the brush portion .

The applicator is
a holding part located on the base side of the applicator and held by the shaft part;
a rod-shaped part extending from the holding part toward the distal end side of the applicator, having the protruding part protruding from the outer peripheral surface, having the brush part around the periphery, and having the distal application part at the distal end;
It is preferable that the protruding part is formed of a material having a lower hardness than the holding part, the rod-shaped part, and the tip application part.

The slit valve included in the application container of the present invention is pushed so that the upwardly convex partition wall is rolled up downward by the applicator that is pressed when the cap with applicator is attached. When the cap with applicator is removed, the partition wall that has been rolled up downward returns to its original state while remaining in contact with the applicator moving upward. That is, since the partition wall of the slit valve remains in contact with the applicator until the applicator moving upward comes out of the partition, any excess liquid remaining at the tip of the applicator can be scraped off.

FIG. 1 is a sectional view in an upright position showing one embodiment of a coating container according to the present invention. FIG. 2 is a sectional view and a bottom view of the slit valve shown in FIG. 1 in plan view. It is a figure shown about the situation where the cap with an applicator is removed from the mouth part. It is a figure shown about the state where the content liquid is applied with the cap with the removed applicator, and (a) shows the state where mascara is applied, and (b) shows the state where eyeliner is drawn. It is a figure showing a modification of an application part.

Hereinafter, one embodiment of a coating container (coating container 10) according to the present invention will be described with reference to the drawings. In this specification, etc., the "up" direction and the "down" direction refer to a state in which the application container 10 is in an upright position as shown in FIG. This refers to the orientation when the main body (code 3) is positioned upward.

The application container 10 of this embodiment includes a container body 1 and a squeezing member 2, which constitute a "container" in this specification and the like. Further, the coating container 10 includes a lid main body 3, a shaft member 4, and an applicator 5, which constitute a "cap with applicator" in this specification and the like. All of these members are shaped around the axis O as shown in FIG.

The container body 1 is shaped like a cylinder with a bottom. Specifically, the bottom part 1a has a disc shape and is curved upward at the center, a cylindrical body part 1b that rises upward from the edge of the bottom part 1a, and an open upper part and a lower end. It is provided with a cylindrical mouth part 1c which is connected to the body part 1b and whose outer diameter is smaller than the body part 1b, and a male threaded part 1d provided on the outer peripheral surface of the mouth part 1c. The container body 1 also includes a space (housing space S) surrounded by a bottom portion 1a, a body portion 1b, and a mouth portion 1c, and as shown in FIG. The content liquid L to be used is stored.

The straining member 2 is made of a soft material such as rubber or elastomer, and can be elastically deformed. The straining member 2 of this embodiment is attached to the inside of the mouth portion 1c, and before being attached to the container body 1, it has a form as shown in FIG.

As shown in FIG. 2, the ironing member 2 of this embodiment includes a flange portion 2a extending in the horizontal direction, a cylindrical portion 2b extending downward from the inner edge of the flange portion 2a, and a cylindrical portion 2b. It is provided with an engagement protrusion 2c that protrudes radially outward from the outer circumferential surface of. As shown in FIG. 1, when the squeezing member 2 is attached to the container body 1, the flange portion 2a is caught on the upper end of the mouth portion 1c, and the engaging protrusion 2c is caught on the lower end of the mouth portion 1c. , the squeezing member 2 will not fall into the inside of the container body 1 or accidentally slip out from the mouth portion 1c.

The ironing member 2 also includes an ironing cylinder part 2d that protrudes radially inward from the inner circumferential surface of the cylindrical part 2b, slopes downward as it goes radially inward, and has a circular hole in the center. ing. As will be described later, the squeezing cylinder portion 2d is used to scrape off excess liquid L adhering to the applicator 5.

The straining member 2 has an upwardly convex shape below the straining tube portion 2d (with the straining member 2 attached to the inside of the mouth portion 1c, closer to the accommodation space S than the straining tube portion 2d). The partition wall 2e is elastically deformable and has a dome-like shape.

The partition wall 2e is provided with a slit 2f extending through the partition wall 2e. As shown in the bottom view of FIG. 2, the slit 2f of this embodiment has two linearly extending slit portions intersecting at the center of the partition wall 2e to form a cross shape. The central part of 2e is divided into four parts. Since the partition wall 2e is elastically deformable, the slit 2f is normally closed, but when force is applied to the partition wall 2e, the portion separated by the slit 2f is elastically deformed and the slit 2f opens. That is, the portion of the straining member 2 where the partition wall 2e and the slit 2f are provided functions as a slit valve.

The lid main body 3 has a cylindrical shape with a lid, as shown in FIG. The lid main body 3 of this embodiment includes a disk-shaped top wall 3a and a cylindrical outer peripheral wall 3b extending downward from the outer edge of the top wall 3a. Furthermore, a female threaded portion 3c corresponding to the male threaded portion 1d is provided on the inner peripheral surface of the outer peripheral wall 3b.

The shaft member 4 includes an upper annular wall 4a having a circular cylindrical shape. The upper annular wall 4a is formed to fit into the inner circumferential surface of the outer circumferential wall 3b, and thereby the shaft member 4 is held on the lid main body 3. A disk-shaped wall 4b is connected to the lower end of the upper annular wall 4a, and a cylindrical shaft portion 4c extending downward is provided at the center of the disk-shaped wall 4b. A fitting hole 4d for holding the applicator 5 is provided at the tip of the shaft portion 4c. As shown in FIG. 1, the fitting hole 4d of this embodiment has a lower inner diameter smaller than an upper inner diameter.

The applicator 5 includes a holding portion 5a that is located on the base side (upper side) of the applicator 5 and is inserted into the fitting hole 4d and is fitted and held. The holding portion 5a is formed so that the outer diameter at the lower side is smaller than the outer diameter at the upper side in correspondence with the fitting hole 4d, and is thereby firmly held against the shaft member 4. A rod-shaped portion 5b having a circular cross-sectional shape and extending along the axis O is provided below the holding portion 5a. A plurality of protrusions 5c that protrude away from the axis O (radially outward) are provided on the outer circumferential surface of the rod-shaped portion 5b, and these protrusions 5c constitute a brush portion 5d. Furthermore, a conical tip application portion 5e that tapers downward from above is provided at the tip of the rod-like portion 5b.

The applicator 5 may be formed from a single material or from two or more kinds of materials. In this embodiment, the holding part 5a, the rod-shaped part 5b, and the tip application part 5e are formed of a relatively hard material (for example, a synthetic resin such as polypropylene (PP)), while the protruding part 5c is made of a relatively hard material. It is made of a material with low resistance (for example, a soft material such as rubber or elastomer). Note that in order to form one member from a plurality of materials in this way, for example, two-color molding or insert molding may be used.

In such a coating container 10, when attaching the lid body 3 to the container body 1, the lid body 3 is pushed downward while the applicator 5 is inserted inside the squeezing member 2, and as shown in FIG. The male threaded portion 1d and the female threaded portion 3c are screwed together. Here, when the lid main body 3 is pushed downward while inserting the applicator 5 inside the squeezing member 2, the partition wall 2e having a convex shape upward is pushed in by the tip applicator 5e and elastically deforms. Then, as shown in FIG. 1, it comes into contact with the outer peripheral surface of the shaft portion 4c in a state where it is rolled up downward.

Further, in this state, the flange portion 2a of the squeezing member 2 is held between the upper end portion of the mouth portion 1c of the container body 1 and the disc-shaped wall 4b of the shaft member 4. That is, since volatilization of the liquid content L accommodated in the storage space S can be suppressed, the quality of the liquid content L can be maintained even after a relatively long period of time. Further, in this state, since the tip of the squeezing cylinder portion 2d is also in contact with the outer circumferential surface of the shaft portion 4c, volatilization of the content liquid L can be further suppressed.

To apply the liquid content L, the lid main body 3 is rotated with respect to the container main body 1 to release the threaded engagement between the male threaded portion 1d and the female threaded portion 3c, and the lid main body 3 is pulled up as it is. Thereby, the shaft member 4 can be pulled out from the squeezing member 2. Note that, for example, when the container body 1 is tilted, the content liquid L may adhere to the outer circumferential surface of the shaft portion 4c, but the content liquid L may be attached to the outer circumferential surface of the shaft portion 4c toward the tip of the squeezing cylinder portion 2d or downwardly. Since the partition wall 2e is in contact with the lid body 3, the content liquid L adhering to the outer peripheral surface of the shaft portion 4c can be scraped off by pulling up the lid main body 3.

Further, as the lid main body 3 continues to be pulled up, the squeezing cylinder part 2d and the partition wall 2e remain in contact with the outer peripheral surface of the brush part 5d, as shown in FIG. 3(a). This makes it possible to scrape off excess content liquid adhering to the outer circumferential surface of the brush portion 5d.

Then, as the lid main body 3 continues to be pulled up, the tip application portion 5e approaches the partition wall 2e, as shown in FIG. 3(b). The tip application part 5e is tapered from the top to the bottom, but the partition wall 2e, which was rolled up downward, is restored to a convex shape upward, so the partition wall 2e is tapered from the top to the bottom. It remains in contact with the outer peripheral surface of the application section 5e. Therefore, the excess liquid L adhering to the outer peripheral surface of the tip application section 5e can be scraped off by the partition wall 2e until the tip application section 5e comes out of the partition wall 2e as shown in FIG. 3(c).

After pulling up the lid body 3 and pulling out the shaft member 4 and applicator 5 from the squeezing member 2 as described above, as shown in FIG. The content liquid L adhering to the applicator 5 can be applied to the application destination. Since the applicator 5 of this embodiment includes the brush portion 5d, it is possible to apply the liquid content L (mascara in this case) to the eyelashes, as shown in FIG. 4(a). At this time, as described above, since the excess liquid content is scraped off by the brush portion 5d, it is less likely to clump due to eyelashes, and the application work can be performed satisfactorily. Further, since the protruding portion 5c constituting the brush portion 5d is formed of a material with relatively low hardness, the tip of the eyelid will not be damaged during the application operation.

Since the applicator 5 of this embodiment also includes a tip applicator 5e, it is also possible to draw an eyeline as shown in FIG. 4(b). In this case as well, since the excess liquid content is scraped off from the tip application portion 5e, the liquid content L does not adhere too much to the eyelids, and the application work can be performed satisfactorily.

In addition, if you want to further scrape off the liquid content L adhering to the brush part 5d and tip application part 5e, for example when finishing, you can rub the brush part 5d and tip application part 5e against the squeezing cylinder part 2d. good.

As described above, the applicator 5 of this embodiment can be used satisfactorily both when applying the liquid content L to the eyelashes and to the eyelids. That is, in general, there are many tools required for eye makeup, and if you try to use all the tools on the go, your luggage will become bulky, but according to the applicator 5 of this embodiment, you can use it even when applying mascara. It can also be used to draw lines, so it has the advantage of reducing the amount of luggage you carry.

Note that the applicator 5 used in the applicator container 10 is not limited to the one shown in the figure; for example, as shown in FIG. However, it is also possible to use fibers (flocks are flocked at intervals with respect to the wire). In this case as well, by pulling up the lid main body 3, excess liquid content adhering to the tip of the applicator 6 can be scraped off.

Although one embodiment of the present invention has been described above, the present invention is not limited to such specific embodiment, and unless specifically limited by the above explanation, the gist of the present invention described in the claims Various modifications and changes are possible within the range. Furthermore, the effects of the embodiments described above are merely illustrative of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above effects.
