Description

The present invention relates to a container with an applicator, for example, a container with an applicator having a shaft with an applicator formed at the tip for applying liquid cosmetics such as mascara, eyeliner, eyeshadow, and lip gloss.

Conventionally, as shown in FIG. 4, a container with an applicator having a shaft with an applicator formed at the tip for applying a liquid cosmetic product is commonly used, which includes a container body 1 for containing a liquid, a squeezing member 2 attached to the opening 11 of the container body 1, a cap 3, and a shaft 4 with an applicator (not shown) formed at the tip, which is attached to the cap 3 and inserted into the container body 1 via the squeezing member 2.

The scraping member 2 attached to the opening 11 of the container body 1 is intended to scrape off excess liquid cosmetic material adhering to the applicator and the shaft portion 4. However, when the applicator is removed from the container body 1, a pulling force is applied to the scraping member 2, which can cause the scraping member 2 to come out of the container body 1 together with the applicator, or to float up from the opening 11 of the container body 1.
To prevent this, in conventional containers with applicators, the inner diameter of the opening 11 of the container body 1 is made smaller than the inner diameter of the main body portion 12, and a locking portion 20 is formed on the outer peripheral surface of the brush member 2 which is larger than the inner diameter of the opening 11 of the container body 1 but smaller than the inner diameter of the main body portion 12 (see, for example, Patent Documents 1 and 2).

As described above, in conventional containers with applicator, a locking portion is formed on the outer peripheral surface of the handling member to prevent the handling member from slipping out or floating up. However, if the liquid cosmetic at the opening of the container body dries and solidifies, causing the handling member to adhere to the shaft portion formed at the tip of the applicator, a large pulling force is applied to the handling member when the applicator is removed from the container body, resulting in the problem that the handling member cannot be prevented from slipping out or floating up.
To solve this problem, it is necessary to increase the outer diameter of the locking portion, but there are limitations to increasing the outer diameter of the locking portion because this would cause problems when attaching the filtering member to the opening of the container body.

In consideration of the problems with the conventional containers with applicators described above, the first objective of the present invention is to provide a container with an applicator that can prevent the sieving member from coming loose when a large pulling force is applied to the sieving member without causing any problems when the sieving member is attached to the opening of the container body.

The second object of the present invention is to provide a container with an applicator that can prevent the squeegee from floating up and prevent liquid from leaking.

In order to achieve the first object, the container with applicator of the present invention comprises a container body for containing a liquid, a strainer attached to an opening of the container body, a cap, and a shaft portion having an applicator formed at its tip, the shaft portion being attached to the cap and inserted into the container body via the strainer,
The inner diameter of the opening of the container body is smaller than the inner diameter of the main body,
The striking member is characterized in that it has a first engagement portion on its outer surface which is larger than the inner diameter of the opening of the container body and smaller than the inner diameter of the body portion, and a second engagement portion which is located closer to the opening of the container body than the first engagement portion and which acts to increase the outer diameter of the first engagement portion when a pulling force is applied to the striking member.

In order to achieve the second object, the container with applicator of the present invention comprises a container body for containing a liquid, a strainer attached to an opening of the container body, a cap, and a shaft portion having an applicator formed at its tip, the shaft portion being attached to the cap and inserted into the container body via the strainer,
The shaft portion is provided with two or more concentric circular pressure contact portions which come into contact with the upper surface of the striking member.

According to the container with applicator of the present invention, the sieve member is formed with a first locking portion on its outer circumferential surface that is larger than the inner diameter of the opening of the container body and smaller than the inner diameter of the body portion, and a second locking portion that is located closer to the opening of the container body than the first locking portion and acts to increase the outer diameter of the first locking portion when a pulling force is applied to the sieve member. This makes it possible to prevent the sieve member from coming loose when a large pulling force is applied to the sieve member without causing any problems when the sieve member is attached to the opening of the container body.

In addition, by providing the shaft with two or more concentric circular pressure contacts on the upper surface of the striking member, it is possible to prevent the striking member from floating up and prevent liquid from leaking out.

FIG. 11 is a cross-sectional view of a main part showing a conventional applicator-equipped container.

Below, an embodiment of the container with applicator of the present invention will be described with reference to the drawings.

1 and 2 show a first embodiment of a container with an applicator according to the present invention.
This container with applicator, like the conventional container with applicator shown in Figure 4, comprises a container body 1 for containing a liquid, a striking member 2 attached to an opening 11 of the container body 1, a cap 3, and a shaft 4 having an applicator (not shown) at its tip which is attached to the cap 3 and inserted into the container body 1 via the striking member 2.
In this container with applicator, the inside diameter of the opening 11 of the container body 1 is formed to be smaller than the inside diameter of the main body portion 12, and the striking member 2 has a first locking portion 21 on its outer circumferential surface which is larger than the inside diameter of the opening 11 of the container body 1 and smaller than the inside diameter of the main body portion 12, and is located closer to the opening 11 of the container body 1 than the first locking portion 21. When a pulling force is applied to the striking member 2, the first locking portion 21 locks the opening 11 of the container body 1.
In this case, a second engaging portion 22 is formed which acts to increase the outer diameter of the engaging portion 21.

Specifically, as shown in FIG. 2(a), the second locking portion 22 is configured as a flexible, thin-walled ring-shaped piece or a discontinuous protruding piece so that when the stroke member 2 is inserted into the container body 1, it does not cover the first locking portion 21 and does not increase the outer diameter of the first locking portion 21, and as shown in FIG. 2(b), it covers the first locking portion 21 and acts to increase the outer diameter of the first locking portion 21 when the shaft portion 4, which has the applicator at its tip, is removed from the container body 1.

This allows the sieve member 2 to be easily attached to the opening 11 of the container body 1, and also prevents the sieve member 2 from coming loose when a large pulling force is applied to the sieve member 2.

Incidentally, in this embodiment (as well as the conventional applicator-equipped container shown in FIG. 4), the shaft portion 4 is provided with a pressure contact portion 40 that comes into planar contact with the upper surface of the upper edge portion 23 of the striking member 2.

On the other hand, as shown in the second and third embodiments of the container with applicator of the present invention shown in Figure 3, the shaft 4 can be provided with two (or more) concentric circular press contact portions (portions) 41, 42 that abut on the upper surface of the upper edge 23 of the stroker 2.

This prevents the sieve member 2 from floating up, and compared to the pressure contact portion 40 that contacts the upper surface of the upper edge portion 23 of the sieve member 2 in a planar manner, the movement of liquid is blocked between the two (or more) circularly contacting pressure contact portions (portions) 41, 42, thereby reliably preventing leakage of liquid.

The container with applicator of the second embodiment shown in FIG. 3(a) has a lower surface of the pressing contact portion 40 formed as an inclined surface that is lower on the inner periphery side, thereby forming a pressing contact portion (portion) 42 with the upper surface of the upper edge portion 23 of the scraping member 2.

The applicator-equipped container of the third embodiment shown in FIG. 3(b) has an inclined surface on the upper surface of the upper edge 23 of the scraping member 2 that is lower on the inner periphery side, and an annular hanging piece is formed on the inner periphery side of the pressing contact portion (portion) 41 of the pressing contact portion 40, thereby forming a pressing contact portion (portion) 42 with the upper surface of the upper edge 23 of the scraping member 2.

In this way, by forming the lower surface of the pressure contact portion 40 into an inclined surface that slopes downward toward the inner circumference, or by forming the upper surface of the upper edge portion 23 of the striking member 2 into an inclined surface that slopes downward toward the inner circumference, the formation of pressure contact portions (portions) 41, 42 reduces the contact area between the upper surface of the upper edge portion 23 of the striking member 2 and the pressure contact portion 40, making it less likely for liquid to accumulate.
This makes it difficult for the liquid to solidify, and prevents a large pulling force from acting on the straining member 2 when the applicator is removed from the container body 1 .
Furthermore, the outer diameter of the first engaging portion 21 (the same applies to the engaging portion 20 of the conventional applicator-equipped container shown in Figure 4) can be reduced, thereby improving operability when attaching the striking member 2 to the opening 11 of the container body 1.

The container with applicator of the present invention has been described above based on its embodiment, but the present invention is not limited to the configuration described in the above embodiment, and the configuration can be changed as appropriate within the scope of the spirit of the present invention.

The container with applicator of the present invention can prevent the squeegee from coming off when a large pulling force is applied to the squeegee without causing any trouble when the squeegee is attached to the opening of the container body, and further has the characteristics of preventing the squeegee from floating up and preventing liquid from leaking. Therefore, it can be suitably used as a container with applicator having a shaft with an applicator formed at the tip for applying liquid cosmetics such as mascara, eyeliner, eyeshadow, and lip gloss.
