By the way, in a state where the applicator is inserted into the container body, the inside of the container body is sealed by the squeezing piece and the applicator, so that the pressure inside the container body increases and decreases each time the applicator is taken in and out. In particular, when the applicator is inserted, the pressure inside the container body may increase excessively. Thereafter, when the applicator is extracted, the air inside the container body is ejected and at the same time the liquid is scattered outside the container body. There is a fear.
Patent Document 1 discloses that a vertical rib is formed on the outer peripheral surface of the applicator in order to solve this problem. In this case, the outer peripheral surface of the applicator is also removed when the applicator is extracted. There is a possibility that a gap is formed between the inner peripheral edge of the ironing piece, and excess liquid adhering to the applicator cannot be sufficiently scrubbed off.

  The present invention has been made in consideration of such circumstances, and prevents an excessive increase in the pressure inside the container body when the applicator is inserted, and is extra when the applicator is withdrawn from the container body. An object of the present invention is to provide a container with an applicator capable of sufficiently scrubbing off a liquid.

In order to solve this problem, a container with an applicator according to the present invention includes a container body that stores a liquid, a cap that is detachably attached to a mouth tube portion of the container body, and is fixed to the cap and the cap. A rod-shaped applicator accommodated inside the container body in a state of being mounted on the mouth tube portion, and the container disposed inside the container body and gradually moving downward in the axial direction of the container body A squeezing piece that is formed in a cylindrical shape extending inward in the radial direction of the body and through which the applicator is inserted, and the squeezing piece has an inner diameter dimension at the lower end in the axial direction of the applicator. It is formed so as to be smaller than the outer diameter dimension, and is formed so as to be elastically deformable along with the movement of the applicator along the axial direction, and a plurality of lower end portions in the axial direction on the inner peripheral surface of the ironing piece rib is projected, the cap While wearing the mouth tube portion of the container body, the portion positioned in the axial direction below the lower axial end of the wiping strip in the applicator, and wherein a step portion is formed.

  According to the container with the applicator of the present invention, when the applicator is inserted into the container body while being inserted inside the ironing piece, the axial lower end of the ironing piece is placed in the axial direction of the container body by the outer peripheral surface of the applicator. Elastically deforms so that it turns downward. At this time, since the rib formed on the inner peripheral surface of the lower end portion of the ironing piece is pressed against the outer peripheral surface of the applicator by the elastic force of the ironing piece, the inner peripheral surface of the lower end portion of the ironing piece is in contact with the outer peripheral surface of the applicator tool. It becomes non-contact with respect to it. Therefore, when the applicator is inserted into the container body, the frictional force generated between the applicator and the iron piece can be weakened. Also, the outer peripheral surface of the applicator and the axial lower end of the iron piece can be reduced. A gap can be formed between them.

And since a clearance gap arises between the outer peripheral surface of an applicator tool, and the axial direction lower end of an ironing piece, since the inside of a container body is connected to the exterior, the pressure inside a container body rises with insertion of an applicator tool. Can be prevented.
Further, since the frictional force generated between the applicator and the iron piece is weakened, the operability in inserting the applicator is enhanced.

On the other hand, when the applicator is pulled out from the inside of the container body, the lower end portion of the ironing piece is elastically deformed so as to be turned up in the axial direction of the container body. Power rises. Therefore, the lower end in the axial direction of the squeezing piece is pressed against the outer peripheral surface of the applicator over the entire circumference, and excess liquid adhering to the outer peripheral surface of the applicator can be surely scraped off by the squeezing piece.
Furthermore, in the process of extracting the applicator, the lower end in the axial direction of the ironing piece is caught by the stepped portion, and the lower end portion of the ironing piece is turned up in the axial direction of the container body by the stepped portion. Excess liquid adhering to the outer peripheral surface of the applicator can be more reliably scraped off.

In the applicator-equipped container, the plurality of ribs may be arranged at equal intervals along the circumferential direction of the ironing piece.
In this case, when the applicator is inserted into the container body, the frictional force generated between the applicator and the iron piece can be weakened uniformly over the entire circumference of the iron piece, These communication paths (gap) can be provided uniformly.

Furthermore, in the said container with an applicator, the said rib may be formed in hemispherical shape.
In this case, the contact between the outer peripheral surface of the applicator and the rib can be point contact, and the contact area can be suppressed. Therefore, when inserting the applicator, a gap can be reliably formed between the outer peripheral surface of the applicator and the axial lower end of the ironing piece, and the applicator can be inserted with a small force. It becomes.

In the container with the applicator, when the applicator is elastically deformed by inserting the applicator into the container body while being inserted inside the iron, the inner periphery of the iron The rib may be arranged so as to form a gap between the lower end of the surface in the axial direction and the outer peripheral surface of the applicator .
In this case, when the applicator is pulled out, the lower end in the axial direction of the ironing piece is surely pressed against the outer peripheral surface of the applicator over the entire circumference, so that excess liquid adhering to the outer peripheral surface of the applicator can be reliably Can be squeezed off.

According to the present invention, when the applicator is inserted into the container body, an excessive increase in pressure inside the container body can be prevented, so that when the applicator is withdrawn from the container body, the liquid is removed from the container body. Prevents splashing outside.
Also, when the applicator is pulled out of the container body, the lower end in the axial direction of the squeezing piece is pressed against the outer peripheral surface of the applicator over its entire circumference, so that the excess liquid adhering to the outer peripheral surface of the applicator is sufficiently scrubbed off. be able to.

Embodiments of a reference example of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the container A with an applicator according to this embodiment is fixed to the container body 1, a cap 10 that is detachably attached to the mouth tube portion 2 of the container body 1, and the cap 10. An applicator 20 and a ironing member 30 disposed inside the container body 1 are provided.
The container body 1 has a shoulder portion that is gradually reduced in diameter as it goes upward at the upper end (upper side in FIG. 1) of the bottomed cylindrical barrel portion 3 that contains liquid such as cosmetic liquid, chemical liquid, adhesive liquid, and cleaning liquid. 4 is connected to the upper end of the shoulder 4, and a mouth tube 2 extending upward along the axis L <b> 1 of the container body 1 is connected to the upper end of the shoulder 4. A male screw 2 </ b> A is formed on the outer peripheral surface of the mouth tube portion 2.
Specific examples of the cosmetic liquid described above include mascara, eyeliner, lip gloss, and the like.

The cap 10 includes an attached cylinder portion 11 in which a female screw 11A that can be screwed into the male screw 2A of the mouthpiece portion 2 is formed, and is thereby detachable from the mouthpiece portion 2. Further, the cap 10 includes a fixing cylinder 12 that is connected to the upper end of the adherend cylinder 11 and extends upward along the axis L1.
The applicator 20 is formed in a rod shape whose outer diameter is sufficiently smaller than the inner diameter of the cap 10 and the mouth tube portion 2, and a large-diameter cylindrical portion 21 fitted to the inside of the fixing tube portion 12 at the upper end thereof. Is formed. The applicator 20 extends downward along the axis L <b> 1 in a state of being fixed to the cap 10, and is accommodated inside the container body 1 with the cap 10 attached to the mouth tube part 2. Although not shown, an applicator that can contain a liquid is provided at the lower end of the applicator 20. Specific examples of the application portion include brush shapes, brush shapes, sponge shapes, and the like.

The ironing member 30 is made of an elastically deformable soft material such as nitrile rubber (NBR), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), etc. A cylindrical portion 31 that is fixed to the cylindrical portion 2 and extends in the direction of the axis L1 and an ironing piece 32 that is integrally formed on the inner peripheral surface 31a of the cylindrical portion 31 are provided.
The cylindrical part 31 is fitted in the mouth cylindrical part 2, and a flange part 33 is projected from the upper end of the cylindrical part 31 outward in the radial direction. The flange portion 33 is in contact with the upper end surface of the mouth tube portion 2 so that the ironing member 30 is positioned relative to the mouth tube portion 2 in the direction of the axis L1.

The ironing piece 32 is provided at an intermediate portion in the direction of the axis L1 on the inner peripheral surface 31a of the cylindrical portion 31, and gradually goes inward in the radial direction of the container body 1 as it goes downward in the direction of the axis L1 of the container body 1. It is formed in a cylindrical shape that extends. The applicator 20 described above is inserted inside the ironing piece 32 while being accommodated in the container body 1.
Here, since the inner diameter dimension at the lower end 32a in the axial line L1 direction of the ironing piece 32 (hereinafter referred to as the axial lower end 32a) is formed smaller than the outer diameter dimension of the applicator 20, the ironing piece 32 is elastically deformed. By doing so, the applicator 20 can pass through the inside of the ironing piece 32 at the lower end 32a in the axial direction.

  Further, the ironing piece 32 is formed so as to be elastically deformed as the applicator 20 moves in the direction along the axis L1. That is, when the applicator 20 is moved downward along the axis L <b> 1 in a state where the applicator 20 is inserted inside the ironing piece 32, the axial lower end 32 a of the ironing piece 32 is caused by the outer peripheral surface 20 a of the applicator 20. The ironing piece 32 is elastically deformed so as to be turned downward in the direction of the axis L1 of the container body 1 (see FIG. 3). Further, when the applicator 20 is moved upward along the axis L1, the ironing piece 32 is elastically deformed so that the axial lower end 32a of the ironing piece 32 is turned upward in the axis L1 direction of the container body 1 (see FIG. 4). .

  A plurality of (four in the illustrated example) ribs 34 project from the lower end portion of the inner circumferential surface 32b of the ironing piece 32 in the direction of the axis L1. Each rib 34 is formed in a hemispherical shape, and is arranged with a space between the inner peripheral surface 32b of the ironing piece 32 and the lower end 32c in the direction of the axis L1. That is, the thickness of the axially lower end 32 a of the ironing piece 32 is formed thinner than the thickness at the position where the rib 34 is formed. Further, the plurality of ribs 34 are arranged at equal intervals along the circumferential direction of the ironing piece 32.

  In the container A with the applicator configured as described above, as shown in FIG. 3, when the applicator 20 is inserted into the container body 1 while being inserted inside the ironing piece 32, as described above. The lower end portion 32e in the axial direction of the ironing piece 32 is elastically deformed so as to be turned down in the direction of the axis L1 of the container body 1. The lower end portion 32e of the ironing piece 32 indicates a lower portion of the ironing piece 32 including the axial lower end 32a and the position where the rib 34 is formed.

In this way, the rib 34 is pressed against the outer peripheral surface 20a of the applicator 20 by the elastic force of the ironing piece 32 by elastically deforming the ironing piece 32 so that the inner peripheral surface of the lower end portion 32e of the ironing piece 32 is obtained. 32 b is not in contact with the outer peripheral surface 20 a of the applicator 20. Accordingly, when the applicator 20 is inserted into the container body 1, the frictional force generated between the applicator 20 and the ironing piece 32 can be weakened, and the outer peripheral surface 20 a of the applicator 20 and the ironing piece 32 can be reduced. A gap can be formed between the lower end 32a in the axial direction.
Here, since the rib 34 is formed in a hemispherical shape, the contact between the applicator 20 and the rib 34 when the applicator 20 is inserted becomes a point contact, and the contact area can be suppressed. Thereby, when the applicator 20 is inserted, a gap can be surely formed between the outer peripheral surface 20a of the applicator 20 and the axial lower end 32a of the ironing piece 32, and the frictional force described above is further increased. Can weaken.

  Further, since the plurality of ribs 34 are arranged at equal intervals along the circumferential direction of the ironing piece 32, when the applicator 20 is inserted as described above, the rib 34 is interposed between the applicator 20 and the ironing piece 32. The generated frictional force can be weakened evenly over the entire circumference of the ironing piece 32, and the communication path between the inside and the outside of the container body 1 including the gaps described above can be evenly provided.

On the other hand, as shown in FIG. 4, when the applicator 20 is extracted from the inside of the container body 1, the lower end portion 32 e of the ironing piece 32 is elastically deformed so as to be turned upward in the axis L <b> 1 direction of the container body 1. This elastic deformation is performed so that the axial lower end 32a of the ironing piece 32 enters the inner side of the ironing piece 32 itself, so that the elastic force presses the axial lower end 32a of the ironing piece 32 against the outer peripheral surface 20a. Power rises. Therefore, the lower end 32a in the axial direction of the squeezing piece 32 is pressed against the outer peripheral surface 20a of the applicator 20 over the entire circumference, and the excess liquid attached to the outer peripheral surface 20a of the applicator 20 is reliably squeezed by the squeezing piece 32. Can be dropped.
Here, since the rib 34 is arranged with a space between the inner peripheral surface 32b of the ironing piece 32 and the lower end 32c in the direction of the axis L1, the ironing piece 32 is taken out when the applicator 20 is extracted. Can be reliably pressed against the outer peripheral surface 20a of the applicator 20 over its entire circumference.

As described above, according to the applicator-equipped container A according to the above-described embodiment, when the applicator 20 is inserted into the container body 1, the lower end in the axial direction of the outer peripheral surface 20 a of the applicator 20 and the ironing piece 32. Since a gap can be formed between the container 32 and the container body 1, an excessive increase in pressure inside the container body 1 can be prevented, and when the applicator 20 is extracted from the container body 1, the liquid splatters outside the container body 1. Can be prevented.
Further, when the applicator 20 is extracted from the container body 1, the entire axial lower end 32 a of the squeezing piece 32 is pressed against the outer peripheral surface 20 a of the applicator 20, so that excess liquid adhered to the outer peripheral surface 20 a of the applicator 20. Can be removed with sufficient and certainty.
Further, when the applicator 20 is inserted, the frictional force generated between the applicator 20 and the squeezing piece 32 can be weakened, so that the applicator 20 can be inserted with a small force. Can be increased.

Next, a description will be given of an embodiment of the present invention, the the same site as the embodiment and a description thereof will be omitted given the same reference numerals, and only different points will be explained.

In the container B with an applicator according to the present embodiment, as shown in FIG. 5, the lower end 41b in the axial direction of the squeezing piece 41 in the applicator 40 with the cap 10 mounted on the mouth tube part 2 of the container body 1. A step portion 42 is formed at a portion located below the axis L1 direction.
In the illustrated example, in the applicator 40, a portion 40a connected to the step portion 42 from above in the axis L1 direction has a smaller outer diameter than a portion 40b continuous to the step portion 42 from below in the axis L1 direction.
Further, the ironing piece 41 gradually extends linearly inward in the radial direction of the container body 1 as it goes downward in the direction of the axis L1 of the container body 1. Then, with the cap 10 attached to the mouth tube portion 2 of the container body 1, the tip 41 a of the squeezing piece 41 protrudes into the portion 40 a that continues from the upper side in the axis L 1 direction to the stepped portion 42 on the outer peripheral surface 20 a of the applicator 40. It has been applied. Further, the lower end 41b and the front end 41a of the ironing piece 41 are opposed to the stepped portion 42 in the direction of the axis L1.

As described above, according to the container B with an applicator according to the present embodiment, in addition to the operational effects exhibited by the container A with an applicator shown in FIGS. 1 to 4, in the process of extracting the applicator 40, FIG. ), When the lower end 41b in the axial direction of the ironing piece 41 is hooked on the step portion 42, the lower end portion 32e of the ironing piece 41 is formed as shown by the solid line in FIG. 5C. will be raised turning the axial line L1 direction above the container body 1 by the stepped portion 42, it can be dropped ironing excess liquid adhering to the outer peripheral surface of the applicator 40 by wiping piece 41 more reliably.

  Furthermore, in the present embodiment, the ironing piece 41 gradually extends linearly inward in the radial direction of the container body 1 as it goes downward in the direction of the axis L1 of the container body 1, and thus the ironing piece as described above. When the lower end 41b in the axial direction of 41 is caught by the stepped portion 42, it becomes possible to apply a bending force to the squeezing piece 41, and the squeezing piece 41 can be easily and reliably removed in the direction of the axis L1 in the process of extracting the applicator 40. It can be turned up.

As mentioned above, although the container A with an application tool which is embodiment of the reference example of this invention and the container B with application tool which is one embodiment of this invention were demonstrated, the technical scope of this invention is limited to this. However, it can be appropriately changed without departing from the technical idea of the present invention.
For example, even if a plurality of ribs 34 are arranged at non-uniform intervals along the circumferential direction of the ironing pieces 32, 41, or even if arranged on the lower end 32c in the direction of the axis L1 on the inner peripheral surface 32b of the ironing pieces 32, 41, It is possible to prevent the pressure inside the container body 1 from increasing when the applicators 20 and 40 are inserted, and it is possible to sufficiently squeeze out the liquid when the applicators 20 and 40 are extracted.

Further, the number of ribs 34 is not limited to a plurality, and for example, only one rib 34 may be provided.
Moreover, in the said embodiment, although the rib 34 was formed in hemispherical shape, if it protruded at least on the inner peripheral surface 32b of the ironing pieces 32, 41, the outer peripheral surface 20a of the applicator 20, 40 By appropriately setting the dimensions and shape of the ribs 34 so as to reduce the contact area, the distance between the outer peripheral surface 20a of the applicators 20 and 40 and the lower end 32a in the axial direction of the ironing piece 32 and the tip 41a of the ironing piece 41 can be reduced. It is possible to form a gap in the gap.

In addition, the ironing pieces 32 and 41 are connected to the intermediate portion of the cylindrical portion 31 in the direction of the axis L1. However, the ironing pieces 32 and 41 may be disposed at least inside the container body 1. It may be connected to the lower end portion in the direction of the axis L1.
Furthermore, although the ironing pieces 32 and 41 are formed on the ironing member 30 separate from the container body 1, the ironing pieces 32 and 41 may be integrally formed on the inner peripheral surface of the mouth tube portion 2 of the container body 1, for example. This configuration can be applied, for example, by using the applicator-equipped container A as a tube body.

Also, instead of the applicator-equipped container B shown in FIG. 5, as shown in FIG. 6, ironing is performed on the outer peripheral surface 20 a of the applicator 40 with the cap 10 attached to the mouth tube portion 2 of the container body 1. An applicator-equipped container C in which an annular groove 43 is formed in a portion corresponding to the piece 41 may be adopted, and the lower end portion of the annular groove 43 in the direction of the axis L <b> 1 may be the stepped portion 42.
5 and FIG. 6, as the ironing piece 41, the structure gradually extending linearly inward in the radial direction of the container body 1 toward the lower side in the axis L1 direction of the container body 1 is shown. Instead, for example, a configuration may be adopted in which the container body 1 gradually extends inward in the radial direction toward the lower side in the axis L1 direction.
5 and 6 show a configuration in which the tip 41a of the ironing piece 41 is abutted against the outer peripheral surface 20a of the applicator 40 in a state where the cap 10 is attached to the mouth tube portion 2 of the container body 1. Instead of this, if at least the tip 41a of the squeezing piece 41 and the stepped portion 42 are opposed to each other in the direction of the axis L1, there is a gap between the tip 41a of the squeezing piece 41 and the outer peripheral surface 20a of the applicator 40. May be provided.
