Description

The present disclosure relates to a container for applying a liquid content contained therein.

Conventionally, various containers have been known. Japanese Unexamined Patent Publication No. 2016-87094 describes a container body having a storage portion for accommodating a liquid content, a brush attached to the tip end side of the container body to apply the liquid content, and a liquid content contained in the storage unit. A container with a relay core for sending an object to a brush and a bellows member surrounding the relay core is described.

The rear end portion of the brush is held on the tip surface of the bellows member by a brush holding portion whose diameter is expanded from the rear end of the brush. Further, the brush is held by a brush holder housed on the tip side of the bellows member and inside the container body. A part of the tip side of the brush holder protrudes from the container body, and the brush holder bundles the brushes at a part of the tip side. By bundling the brushes with the brush holder, the tip of the brush is trimmed into a sharp shape.

Japanese Unexamined Patent Publication No. 2016-87094

By the way, in the above-mentioned container, the relay core exhibits a capillary phenomenon, and the liquid contents are sent to the brush by the capillary phenomenon. However, especially in recent years, the types of liquid contents contained in the storage portion have been diversified, such as the use of liquid cosmetics containing pearls as liquid contents. Therefore, depending on the type of the liquid content, the capillary force may be insufficient and the capillary phenomenon may not be appropriately exhibited, so that the liquid content may not be sufficiently supplied to the brush. If the supply of the liquid content to the brush is insufficient, the application of the liquid content may be troublesome, so there is room for improvement in terms of the usability of the container.

An object of the present disclosure is to provide a container capable of sufficiently supplying a liquid content to a brush and improving the usability.

The container according to the present disclosure is arranged inside a container body having an accommodating portion for accommodating liquid contents and a front cylinder portion which is formed in a tubular shape and has a tubular hole communicating with the accommodating portion. A brush that protrudes from the cylinder hole to the opposite side of the housing part, a relay core that is placed inside the container body and sends out the liquid contents contained in the storage part to the brush, and the inner surface of the tip cylinder part. It is provided with a tubular brush converging member which is arranged between the brush and the tip cylinder portion and is elastically deformable in the radial direction.

In this container, the liquid contents are stored in the storage portion of the container body. The liquid contents contained in the storage portion are sent to the brush placed inside the tip cylinder portion by the relay core arranged inside the container body. A tubular brush converging member is arranged between the inner surface of the tip tube and the brush. The brush converging member converges the brush inside the tip cylinder portion and is elastically deformable in the radial direction of the tip cylinder portion. Since the brush converging member that converges the brush is elastically deformable, the brush can be converged by an appropriate elastic force, so that the capillary force is increased and the liquid content is sufficiently supplied from the relay core to the brush. It is possible to promote the delivery of liquid contents to the brush. Specifically, for example, when the brush converging member is a rigid body and cannot be elastically deformed, the converging force for the brush may be too strong or too weak, and the supply of the liquid content to the brush may be insufficient. .. On the other hand, when the brush converging member is elastically deformable in the radial direction, the converging force on the brush can be appropriately adjusted to increase the capillary force. Therefore, the liquid content on the brush can be obtained by appropriately tightening the brush. Can be sufficiently supplied. As a result, the liquid content can be applied smoothly, so that the usability of the container can be improved.

Further, the brush converging member may have an air flow portion for flowing air along the axial direction of the tip cylinder portion between the brush converging member and the inner surface of the tip cylinder portion. In this case, the brush converging member has an air flow portion extending in the axial direction between the brush converging member and the tip cylinder portion, and an air flow portion extending in the axial direction is formed between the brush converging member and the tip cylinder portion to form the brush. Air recirculation can be formed inside and outside. Therefore, air flows from the air flow section between the brush converging member and the tip cylinder portion toward the relay core, and the delivery of the liquid content from the relay core to the brush can be promoted accordingly. Further, the space between the brush converging member and the tip cylinder portion can be effectively used as a space for recirculating air.

Further, the air flow portion may be recessed from the outer surface of the brush converging member and may have a concave shape extending in the axial direction. In this case, since air can be passed through the concave air flow portion, it is possible to avoid an increase in the diameter of the brush converging member, and the air can be smoothly flowed through the concave air flow portion along the axial direction. Can be done. Therefore, by smoothly flowing the air along the axial direction, the liquid content can be supplied to the brush more smoothly.

Further, at least a part of the brush converging member may have a corrugated shape extending along the circumferential direction of the brush converging member. In this case, at least a part of the brush focusing member has a bellows shape. Therefore, on the inner surface of the brush converging member, the brush can be pressed inward in the radial direction by the protruding portion having a short radial length, and a part of the brush can escape to the recess having a long radial length. Can be done. Therefore, it is possible to increase the surface tension of the liquid content between the bristles in the brush and between the bristles and the inner surface of the brush converging member to further promote the transmission of the liquid contents in the axial direction. As a result, the liquid content in the brush can be supplied more smoothly.

According to the present disclosure, it is possible to sufficiently supply the liquid content to the brush and to improve the usability.

It is a vertical sectional view of the container of FIG. It is a side view which shows the brush converging member of the container of FIG. It is a perspective view which shows the brush convergence member of FIG. It is a front view which shows the brush convergence member of FIG. FIG. 5 is a cross-sectional view schematically showing an enlarged state of a part of the brush converging member and the brush of FIG.

Hereinafter, embodiments of the container according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicate description will be omitted as appropriate.

FIG. 1 is a side view of the container according to the present embodiment. FIG. 2 is a side view showing a state in which the cap is removed from the container of FIG. As shown in FIGS. 1 and 2, the container 100 according to the present embodiment contains the liquid content L (see FIG. 3), and the user applies the liquid content L with the brush 3. The liquid content L is, for example, a liquid cosmetic such as an eyeliner or a lip liner, and the container 100 is a liquid cosmetic container. The container 100 has, for example, a round bar shape extending in the axial direction D1.

In the present specification, the "axis" and the "axis line" indicate the center line extending along the longitudinal direction of the container 100 in the container 100, and the "axis direction" is the direction along the axis line of the container 100 (the axis direction). For example, the longitudinal direction of the container 100) is shown. Further, the direction in which the brush 3 protrudes in the container 100 may be described as "front", and the opposite direction may be described as "rear". However, these directions are for convenience of explanation and do not limit the position or orientation of the object.

FIG. 3 is a vertical sectional view of the container 100. As shown in FIG. 3, the container 100 includes a container main body 1 having an accommodating portion 1c and a tip cylinder portion 1d for accommodating the liquid content L, and a liquid attached to the tip of the container main body 1 and accommodating in the accommodating portion 1c. It includes a brush 3 for applying the content L, a relay core 4 for sending the liquid content L to the brush 3, and a tubular bellows member 5 surrounding the relay core 4. The accommodating portion 1c has, for example, a cylindrical shape, and is provided behind the relay core 4 and the bellows member 5. The cylinder hole 1f of the tip cylinder portion 1d communicates with the accommodating portion 1c. In the present embodiment, the gripping cylinder 6 is attached to the container body 1 so that the user can easily hold the container 100 and apply the coating.

The container body 1 has, for example, a cylindrical shape. However, the shape of the container body 1 is not limited to a cylindrical shape, and may be another shape such as a rectangular cylinder. The gripping cylinder 6 has, for example, a bottomed cylindrical shape, and is attached to the container body 1 by screwing. The container body 1 is made of, for example, PP (Polypropylene). The container body 1 has, for example, a collar portion 1b near the center in the axial direction D1.

The tip cylinder portion 1d is provided on the front side of the flange portion 1b, and has a tapered shape that decreases in diameter toward the front side. The front end surface of the gripping cylinder 6 is abutted against the rear end surface of the collar portion 1b, and the open end surface of the rear end of the cap 8 described later is abutted against the front end surface of the collar portion 1b. Further, a bottomed cylindrical tail plug 7 is inserted into the opening at the rear end of the container body 1, and the tail plug 7 closes the opening at the rear end of the container body 1.

A bottomed cylindrical cap 8 that protects the brush 3 and the like is detachably attached to the front side of the container body 1. The cap 8 is attached to the tip cylinder portion 1d of the container body 1. The cap 8 is an outer cap that constitutes the appearance of the container body 1, and an inner cap 9 is provided inside the cap 8. The inner cap 9 is urged to the container body 1 side (rear side) by the coil spring C. When the cap 8 is attached to the container body 1, the inner cap 9 comes into close contact with the outer surface of the tip cylinder portion 1d to ensure airtightness and suppress the volatilization of the liquid content L.

The bellows member 5 is a member that controls the flow of the liquid content L, and has a groove (bellows) containing the liquid content L. The bellows member 5 is attached to the container body 1 by fitting the annular rear end portion 5a into the recess 1a on the inner peripheral surface of the container body 1. An accommodating portion 1c is formed between the rear end portion 5a of the bellows member 5 provided inside the container body 1 and the tail plug 7.

The relay core 4 is made of, for example, an acrylic resin. The relay core 4 extends in the axial direction D1 inside the tubular bellows member 5. The relay core 4 is attached to the bellows member 5 by fitting a part of the relay core 4 inside the bellows member 5. The portion including the rear end of the relay core 4 has entered the inside of the accommodating portion 1c.

The relay core 4 is arranged inside the container body 1, and sends out the liquid content L contained in the accommodating portion 1c to the brush 3. The front portion of the relay core 4 is embedded in the brush 3. In this way, one side (rear side) of the relay core 4 enters the accommodating portion 1c, and the other side (front side) of the relay core 4 enters the brush 3. That is, the relay core 4 is interposed between the liquid content L accommodated in the accommodating portion 1c and the brush 3.

Then, the relay core 4 sucks up the liquid content L inside the accommodating portion 1c by the capillary phenomenon and sends it to the brush 3. Inside the accommodating portion 1c, a stirrer M that is movable and agitates the liquid content L by moving is accommodated together with the liquid content L. The stirrer M is, for example, spherical, but may have other shapes such as a polyhedron or a cone.

The rear portion of the brush 3 is arranged inside the tip cylinder portion 1d, and projects from the cylinder hole 1f of the tip cylinder portion 1d to the opposite side (front side) of the accommodating portion 1c. The brush 3 has a plurality of hairs 3b to which the liquid content L is applied, and an annular brush holding portion 3c located at the rear end of the hairs 3b. The rear end portions of the plurality of hairs 3b are fixed to the brush holding portion 3c. The brush holding portion 3c is sandwiched in the axial direction D1 between the front end surface of the bellows member 5 and the tubular brush converging member 10 described later. As a result, the brush 3 is immovable along the axial direction D1.

FIG. 4 is a side view of the brush converging member 10. FIG. 5 is a perspective view of the brush converging member 10. As shown in FIGS. 3, 4 and 5, the brush converging member 10 is arranged between the brush 3 and the inner surface 1g which is concave inside the tip cylinder portion 1d. The brush converging member 10 has a tubular shape in which convex portions 11 and concave portions 12 extending along the axial direction D1 are alternately arranged along the circumferential direction D2 of the brush converging member 10.

As described above, since the brush converging member 10 includes portions in which the convex portions 11 and the concave portions 12 are alternately arranged, the brush focusing member 10 has a shape that is easily bent in the radial direction D3. The end portion 11b of the convex portion 11 in the axial direction D1 is rounded into a curved surface, for example, and the radius of curvature of the end portion 11b is 0.1 mm as an example.

The material of the brush focusing member 10 is, for example, PP or PE (Poly Ethylene). The brush converging member 10 is elastically deformable in the radial direction D3 of the tip cylinder portion 1d. That is, when an external force is applied to the brush converging member 10 from the outside in the radial direction D3, the brush converging member 10 bends inward in the radial direction D3. For example, the length of the brush focusing member 10 in the axial direction D1 is 5 mm or more and 10 mm or less (6.5 mm as an example). However, the length of the brush focusing member 10 in the axial direction D1 is not limited to the above example and can be changed as appropriate.

FIG. 6 is a front view (viewed from the axial direction D1) of the brush converging member 10. As shown in FIGS. 5 and 6, the brush converging member 10 has a corrugated shape in which the convex portions 11 and the concave portions 12 are alternately arranged along the circumferential direction D2. For example, the convex portions 11 and the concave portions 12 are sinusoidal. They are lined up in a wavy pattern. For example, the plurality of convex portions 11 and the plurality of concave portions 12 are arranged at equal intervals along the circumferential direction D2, and the number of the convex portions 11 and the concave portions 12 is 16.

In this case, the convex portion 11 and the concave portion 12 are both arranged with a phase angle of 22.5 ° (= 360 ° / 16), and the phase angle from the convex portion 11 to the adjacent concave portion 12 is 11.25 °. .. For example, the convex portion 11 and the concave portion 12 are both arcuate, and the radius of curvature of the convex portion 11 and the concave portion 12 is 0.25 mm or more and 0.30 mm or less.

The thickness T of the brush converging member 10 is, for example, constant along the circumferential direction D2, and is 0.2 mm or more and 0.4 mm or less (0.3 mm as an example). The diameter E1 of the convex portion 11 of the brush focusing member 10 is, for example, 5.0 mm or more and 5.5 mm or less (5.3 mm as an example). The inner diameter E2 of the convex portion 11 (diameter of the inner surface 10b of the convex portion 11) is, for example, 4.4 mm or more and 4.8 mm or less (4.6 mm as an example).

FIG. 7 is a diagram schematically showing a cross section of the hair 3b of the brush 3 that is enlarged and converged on the brush convergence member 10 of FIG. As shown in FIGS. 6 and 7, the brush converging member 10 has an air flow portion 13 that allows air to flow along the axial direction D1 between the brush converging member 10 and the inner surface 1 g of the tip cylinder portion 1d.

The air flow portion 13 is, for example, a region defined by the inner surface 1 g of the tip cylinder portion 1d and the concave portion 12 of the brush converging member 10, and the inner surface 1 g and the convex portion 11 of the brush converging member 10 are in close contact with each other. Since the air flow portion 13 extending in the axial direction D1 is formed between the pair of convex portions 11 that are in close contact with each other in this way, it is possible to smoothly flow air to the air flow portion 13 along the axial direction D1. In the present embodiment, since a plurality of air flow units 13 are arranged along the circumferential direction D2, it is possible to further smooth the air flow in the axial direction D1 between the brush converging member 10 and the container body 1. It will be possible.

For example, a brush pressing portion 10f and a brush relief portion 10g are formed on the inner surface 10b of the brush converging member 10, and the brush pressing portion 10f and the brush relief portion 10g are alternately provided along the circumferential direction D2. The brush pressing portion 10f is the inner surface 10b of the concave portion 12, and the brush relief portion 10g is the inner surface 10b of the convex portion 11.

The brush pressing portion 10f presses the bristles 3b of the brush 3 inward in the radial direction D3, and accordingly, the bristles 3b of the brush 3 escape from the brush pressing portions 10f to both sides in the circumferential direction D2 and enter the brush relief portion 10g. In this way, in the brush converging member 10, the hair 3b of the brush 3 can be pressed in the radial direction D3 by the brush pressing portion 10f, and the hair 3b of the brush 3 is released to the brush relief portion 10g so that the inner surface 10b and the brush 3 can be pressed. It can be used as a flow passage for passing the liquid content L in the axial direction D1 between the hair 3b and the hair 3b.

In the container 100 configured as described above, the liquid content L inside the accommodating portion 1c flows out toward the brush 3 (to the front side) through the relay core 4, and is used by the user of the container 100 by the brush 3. Used for application. When the container 100 is shaken by a user or the like, the liquid content L is agitated by the movement of the stirrer M. As a result, the agitated liquid content L can be efficiently supplied to the brush 3.

As described above, in the container 100 according to the present embodiment, the liquid content L is stored in the storage portion 1c of the container body 1. The liquid content L contained in the accommodating portion 1c is sent to the brush 3 arranged inside the tip cylinder portion 1d by the relay core 4 arranged inside the container body 1. A tubular brush converging member 10 is arranged between the inner surface 1g of the tip cylinder portion 1d and the brush 3. The brush converging member 10 converges the brush 3 inside the tip cylinder portion 1d and is elastically deformable in the radial direction D3 of the tip cylinder portion 1d. Since the brush converging member 10 that converges the brush 3 is elastically deformable, the brush 3 can be converged by an appropriate elastic force. Therefore, the capillary force is increased and the liquid content is transferred from the relay core 4 to the brush 3. It is possible to sufficiently supply L to promote the delivery of the liquid content L in the axial direction D1.

Specifically, for example, when the brush converging member is a rigid body and cannot be elastically deformed, the converging force with respect to the brush is too strong or too weak, and the supply of the liquid content L to the brush 3 is insufficient. Can be. On the other hand, when the brush converging member 10 is elastically deformable as described above, the converging force with respect to the brush 3 can be appropriately adjusted to increase the capillary force. Therefore, the brush 3 is appropriately tightened. The liquid content L can be sufficiently supplied to. As a result, the liquid content L can be applied smoothly, so that the usability of the container 100 can be improved.

Further, the brush converging member 10 according to the present embodiment has an air flow unit 13 that allows air to flow along the axial direction D1 of the tip cylinder portion 1d between the inner surface 1 g of the tip cylinder portion 1d. Therefore, the brush converging member 10 has an air flow portion 13 extending in the axial direction D1 from the tip cylinder portion 1d. Therefore, air reflux can be formed inside and outside the brush 3.

Further, air flows from the air flow unit 13 between the brush converging member 10 and the tip cylinder portion 1d toward the relay core 4 (rear side), and along with this, the liquid content L from the relay core 4 to the brush 3 Can be promoted. Therefore, since air can be smoothly flowed into the dead space between the brush converging member 10 and the tip cylinder portion 1d, the liquid content L can be supplied to the brush 3 more smoothly.

Further, the air flow unit 13 according to the present embodiment is recessed from the outer surface 10c of the brush converging member 10 and has a concave shape (recessed portion 12) extending in the axial direction D1. Therefore, since air can flow through the concave air flow portion 13 along the axial direction D1, it is possible to avoid an increase in the diameter of the brush converging member 10, and the concave shape (groove shape) extending along the axial direction D1. ), The air can flow smoothly through the air flow section 13. Therefore, the liquid content L can be supplied to the brush 3 more smoothly.

Further, the brush converging member 10 according to the present embodiment is formed with a corrugated shape extending along the circumferential direction D2 of the brush converging member 10. That is, the brush converging member 10 has a bellows shape. Therefore, of the inner surface 10b of the brush converging member 10, the brush pressing portion 10f, which is a protruding portion having a short length in the radial direction D3, can press the brush 3 inward in the radial direction D3 and presses the brush 3 in the radial direction D3. A part of the brush 3 can be released to the brush release portion 10 g, which is a recess having a long length.

Therefore, the surface tension of the liquid content L between the hair 3b and the hair 3b in the brush 3 and between the hair 3b and the inner surface 10b of the brush focusing member 10 is increased to transmit the liquid content L in the axial direction D1. It can be further promoted. As a result, the liquid content L in the brush 3 can be supplied more smoothly.

For example, even if the brush converging member 10 projects from the cylinder hole 1f of the tip cylinder portion 1d to the opposite side (front side) of the accommodating portion 1c. Good.

Further, in the above-described embodiment, the brush converging member 10 having a corrugated shape extending along the circumferential direction D2 of the brush converging member 10 has been described. However, the corrugated shape of the brush converging member may not be formed on the entire circumference of the brush converging member, or may be formed only on a part of the brush converging member. For example, a corrugated shape may be formed in a part of the circumferential direction D2 of the brush converging member 10, and a corrugated shape may not be formed in the remaining portion of the brush converging member 10 in the circumferential direction D2 and may be flat. ..

Further, in the above-described embodiment, the brush focusing member 10 having 16 convex portions 11 and 16 concave portions 12 has been described.
