Description

container with applicator

technical field

The present invention relates to a container with an applicator, and more particularly to a container with an applicator for the purpose of storing a liquid such as cosmetics and discharging and applying the contained liquid.

Background technique

As a conventional container with a coating tool, for example, there is a container with a coating tool disclosed in Patent Document 1. When the container is not in use, by putting a cover on the container body, the pen base and the pen tube are pushed backward against the force of the spring in the joint, so that the valve seat is crimped on the front end of the valve body. As a result, the outflow of the cosmetic self-storage liquid to the application body is prevented. On the other hand, when in use, by removing the cap from the main body, the pen holder and the pen tube are pushed forward due to the biasing force of the spring, and the valve seat is separated from the valve body. As a result, the cosmetics flow from the storage liquid to the application body.

In addition, in this container, an O-ring is provided between the combination and the barrel from the viewpoint of ensuring watertightness between the combination and the barrel.

Patent Document 1: Japanese Patent Publication No. 3-33303

However, in addition to the valve mechanism including the O-ring, the valve body and the valve seat, the above-mentioned conventional container with a coating tool also needs a spring for applying force to the pen tube in the axial direction. Therefore, its components The number is large and the composition state is inefficient.

Contents of the invention

Therefore, an object of the present invention is to provide a container with an applicator that can reduce the number of components, avoid inefficient configurations, and achieve reduced manufacturing costs.

The container with the applicator of the present invention comprises: a main body having a storage part for storing a liquid and a neck having a communication port communicating with the storage part; The coating tool head connected to the neck; the valve seat located at the rear end of the coating tool head; the partition wall located in the neck and isolating the communication port; set to correspond to the valve seat from the partition wall to the A valve body protruding forward and having a discharge hole for discharging the liquid; and a ring-shaped elastic member provided between the partition wall and the head of the applicator to play a watertight function. The elastic member applies force to the applicator head to separate the valve seat from the valve body. When the coating tool head is pushed backward, the elastic member elastically deforms, and the valve seat approaches or abuts against the valve body.

In this container with a coating tool, the elastic member can not only ensure the watertightness between the partition wall and the brush cover, but also exert force on the brush cover to separate the valve seat from the valve body. Compared with the case where the components that perform these functions are properly arranged, the number of components can be reduced, and an inefficient configuration can be avoided, thereby reducing the manufacturing cost.

The applicator head preferably has a cylindrical brush cover, an applicator fixed in the brush cover, and a pipe member whose rear part is fitted into the brush cover and whose front part is inserted into the applicator member. The valve seat is preferably located at the rear of the pipe member. In this way, the liquid can be supplied to the application unit through the pipe member.

The container with the applicator is preferably further provided with a cap attached to the neck of the main body and having a locking portion for pushing the head of the applicator backward. When the cap is installed on the neck, the head of the applicator is pushed backward by the locking portion, and it is preferable that the elastic member elastically deforms so that the valve seat approaches or abuts against the valve body. When the cover is removed from the neck, the elastic part recovers, and it is advisable to separate the valve seat from the valve body. In this way, the valve mechanism can be automatically opened and closed by attaching and removing the cover.

Preferably, the thickness of the elastic member along the direction of the central axis is greater than the thickness along the direction perpendicular thereto. In particular, the elastic member preferably has a substantially elliptical cross section. Alternatively, the elastic member is preferably provided with an annular groove on at least one of its inner peripheral surface and outer peripheral surface. In this way, since the moving distance of the applicator head can be increased, the degree of freedom in selecting the material for forming the elastic member can be increased.

For the container with the coating tool, it is advisable to be provided with continuous protrusions on the surface of the partition wall receiving the elastic member. In this way, the elastic member can be surely crushed over its entire circumference, so that the watertightness between the partition wall and the applicator head can be ensured more sufficiently.

The neck preferably has a stopper that prevents the applicator head from detaching from the neck. In this way, the applicator head can be prevented from detaching from the neck, and the watertightness between the partition wall and the applicator head can be ensured more sufficiently.

A more complete understanding of the present invention can be obtained through the following detailed description and accompanying drawings. These descriptions and drawings are by way of example only, and should not be construed as limiting the present invention.

The container with the applicator of the present invention can avoid inefficient configuration by reducing the number of parts, and can reliably achieve the effect of reducing the manufacturing cost.

<Example 2>

9 is a sectional view showing the overall structure of a container with a coating tool according to Example 2 of the present invention (when the cover is installed), and FIG. 10 is a sectional view showing the partial structure of the same container (when the cover is installed), and FIG. 11 shows Fig. 12 is a cross-sectional view showing a partial structure of the same container (with the cap removed) as a cross-sectional view of the overall structure of the same container (with the cap removed).

In addition, the same reference numerals as in the first embodiment are assigned to the same constituent elements as in the first embodiment, and detailed descriptions thereof are omitted here.

As shown in FIGS. 9 to 12 , the container with an applicator of the second embodiment differs from the first embodiment in that it includes an annular elastic member 7 having a unique cross-sectional shape.

Here, the annular elastic member 7 has a substantially elliptical cross-sectional shape over its entire circumference. More specifically, the ring-shaped elastic member 7 has an elliptical cross-sectional shape whose major axis is the direction of the central axis and whose minor axis is the direction perpendicular thereto.

Here, the reason why the ring-shaped elastic member 7 is required to be formed into an elliptical cross-sectional shape is to make the ring-shaped elastic member 7 into a shape that can move the brush cover 3 for a relatively long distance, so that the belt coating tool The container becomes capable of realizing its efficient configuration with the annular elastic member 7 made of a wider variety of materials. Therefore, as long as such a function can be exerted, it is also possible to have an annular elastic member having an elliptical cross-sectional shape similar to a rectangular cross-sectional shape with a long central axis direction, or an annular elastic member having an approximately elliptical cross-sectional shape with a long central axis direction. The ring-shaped elastic member replaces the ring-shaped elastic member 7 having an elliptical cross-sectional shape long in the central axis direction.

Specifically, as the ring-shaped elastic member, in addition to being made of synthetic rubber as a general-purpose product, it is also possible to use a relatively hard one that has been considered difficult to ensure the moving distance of the brush cover when the cross-sectional shape is circular. The components made of materials can be used to manufacture ring-shaped elastic parts in a wider range of materials.

That is, the container with the applicator of the second embodiment can realize not only an efficient configuration state, but also an efficient configuration state by the annular elastic member made of a wider variety of materials.

<Example 3>

Fig. 13 is a sectional view showing the overall structure of a container with a coating tool according to Example 3 of the present invention (when the cover is installed), Fig. 14 is a sectional view showing the partial structure of the same container (when the cover is installed), and Fig. A sectional view of the overall structure of the same container (when the cover is removed), Figure 16 is a sectional view showing the partial structure of the same container (when the cover is removed), Figure 17 is a perspective view showing the appearance of the annular elastic member, Figure 18 Fig. 19 is a sectional view showing another part of the same container (when the cover is removed), and Fig. 20 shows another part of the same container. 21 is a cross-sectional view showing another part of the same container (when the lid is removed).

In addition, the same reference numerals as in the first embodiment are assigned to the same constituent elements as in the first embodiment, and detailed descriptions thereof are omitted here.

As shown in FIGS. 13 to 16 , the container with the applicator of the third embodiment differs from the configuration of the first embodiment in that it includes an annular elastic member 16 having a unique cross-sectional shape.

Here, the annular elastic member 16 has an annular groove 16a provided on the outer peripheral surface. The ring-shaped elastic member 16 can elastically deform the groove 16a into a substantially closed state when the cover 5 is mounted on the main body 2 .

In other words, as shown in FIG. 17 , in the annular elastic member 16 of the third embodiment, the groove 16a is formed by concavely sinking the entire circumference of the central region of the outer peripheral surface extending in the axial direction, and the groove 16a is formed in the groove 16a. The opposite upper and lower regions on both sides are respectively provided with side wall portions 16b protruding outward, so that when the cover 5 is installed on the body 2, the annular elastic member 16 can be crushed to the opposite inner surfaces of the two side wall portions 16b. The state of being close to or touching each other.

Here, the reason why the ring-shaped elastic member 16 is required to have the groove 16a in a specific shape is to enable the brush cover 3 to move for a relatively long distance by forming the ring-shaped elastic member 16 so that the tape can be coated. The container of the tool becomes possible to achieve its efficient configuration by means of the ring-shaped elastic part made of a wider variety of materials. Therefore, as long as this effect can be exerted, an annular elastic member 17 having a groove 17a opening only inwardly as shown in FIGS. Instead of the annular elastic member 16 having the grooves 16a opened only outward, the annular elastic member 18 having the grooves 18a opened inwardly and outwardly or another annular elastic member is used.

Specifically, as the ring-shaped elastic member, in addition to a general-purpose synthetic rubber member, it is also possible to use a relatively hard material that has traditionally been considered difficult to ensure the movement distance of the brush cover when the cross-sectional shape is circular. The obtained member can be used to manufacture ring-shaped elastic parts with a wider range of materials.

That is, the container with the coating tool of the present embodiment 3, the same as the container with the coating tool of the embodiment 2, not only can realize the high-efficiency configuration state, but also can be obtained by the ring shape made of a wider range of materials. The elastic member realizes the high-efficiency constitution state.

In addition, this invention is not limited to the said Example, Various deformation|transformation is possible. For example, in addition to using a brush (bristle) 1 made of polyester fibers processed into a tapered tip, porous materials made of sponge, polyethylene, polypropylene, polyurethane, etc. can be used as the coating member. A mat made of fibers such as polyester bundled and bonded with an adhesive, and a plurality of fibers are fluffed on the surface of a tubular member formed of a thermoplastic elastomer or the like with a hole in the center through electrostatic fluffing processing, etc. wait.
