Description

[Technical Field]

[0001] The present disclosure relates to an applicator member for applying an application. [Background technology]

[0002] Patent Document 1 describes a brush tip. The brush tip is inserted into and fixed to a fixing tube, which is inserted into and fixed to a cylindrical shaft. The brush tip is made up of a collection of brush bristles that extend linearly and have a circular cross section, brush bristles that extend curvedly and have a circular cross section, and brush bristles that extend linearly and have a cross section other than a circular shape. This brush tip is manufactured by welding or gluing one end of a mixture of bristles containing the above three types of brush tips. The tip of the brush tip is formed so as to be inclined with respect to a cross section perpendicular to the longitudinal direction of the brush tip.

[0003] Patent Document 2 describes a brush for makeup and face washing. This brush is composed of a brush head, a ferrule that supports the brush head, and a handle that supports the ferrule. The brush head is made of artificial hair, natural hair, or a mixture of artificial and natural hair. The brush head has an inclined portion that is inclined with respect to the axial line of the brush head when viewed from the side. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-30335 [Patent Document 2] Japanese Patent Application Laid-Open No. 2014-113484 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the inclined portion at the end of a brush made of bundled bristles may be formed by cutting the tip of the brush with a blade after the brush is manufactured. In this case, a step of cutting the brush to form the inclined portion is required, which can result in a problem of increased manufacturing costs due to the additional steps required to manufacture the application part. When the inclined portion is formed by cutting the brush, the bundled bristles are cut at an angle, which can result in a problem of variation in the thickness of the bristles' tips. If the thickness of the bristles' tips varies, the lines formed during application may become thicker, resulting in a poor application finish.

[0006] An object of the present disclosure is to provide an applicator member that can avoid an increase in the number of manufacturing steps and prevent poor application finish. [Means for solving the problem]

[0007] (1) The applicator member according to the present disclosure comprises a cylindrical brush holder, a brush having a tip end protruding from an opening located at one end of the brush holder and a base end opposite the tip end, the brush including a plurality of bristles extending from the base end toward the opening, and an inclined portion that inclines the base end relative to a plane perpendicular to the axial direction, which is the direction in which the axis of the brush holder extends.

[0008] This applicator member has a brush containing multiple bristles, and the brush has a tip end that protrudes from an opening located at one end of a cylindrical brush holder. The brush has a base end, which is the end opposite the tip end, from which multiple bristles extend toward the opening. This applicator member has an inclined portion, which inclines the base end with respect to a plane perpendicular to the axial direction. Because the base end of the brush from which the multiple bristles extend is inclined, the tip ends of the multiple bristles are inclined, so the inclined portion can be formed without cutting. This eliminates the need for a brush cutting process, thereby reducing the cost of manufacturing the applicator member. Furthermore, by not cutting the brush, variation in the thickness of the bristles' tips can be avoided, thereby preventing poor application finish.

[0009] (2) In the above (1), the applicator may include a pressing member that presses the brush toward the opening, and the pressing member may have an inclined portion. In this case, the inclined portion of the pressing member presses the base end of the brush, thereby inclining the tip ends of the multiple bristles. Therefore, since the inclined portion can be formed by the pressing member pressing the brush, the applicator can be easily assembled.

[0010] (3) In the above (1) or (2), the base end may be a flange portion that expands in diameter relative to the remaining portion of the brush. The brush holder may have a step portion that protrudes from the inner surface of the brush holder. The flange portion may be sandwiched between the step portion and the inclined portion. In this case, the flange portion, which is the base end of the brush, is sandwiched between the step portion and the inclined portion of the brush holder, thereby more reliably maintaining the inclined state of the brush.

[0011] (4) In the above (1) or (2), the brush holder may have a rib that protrudes from the inner surface of the brush holder and bites into the brush moving inside the brush holder toward the opening. In this case, the rib can bite into the brush when the brush is assembled inside the brush holder. Therefore, the assembled brush can be prevented from moving toward the opening.

[0012] (5) In any of (1) to (4) above, the opening may have a flat shape with a long axis and a short axis when viewed along the axial direction. In this case, the tip of the brush protruding from the opening has a flat shape with a long axis and a short axis. Therefore, by contacting the flat tip of the brush with the surface to be coated, thick and thin lines can be freely drawn on the surface to be coated. This improves the quality of application by the brush bristles.

[0013] (6) In the above (2), the applicator may include a container body having a storage section for storing the liquid content to be supplied to the brush, and a bellows member for adjusting the amount of the liquid content to be supplied to the brush. The bellows member may be a pressing member. In this case, the bellows member for adjusting the amount of the liquid content to the brush can be effectively used as the pressing member. [Effects of the Invention]

[0014] According to the present disclosure, it is possible to avoid an increase in the number of manufacturing steps and prevent poor coating finish. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, an embodiment of an application member according to the present disclosure will be described with reference to the drawings. In the description of the drawings, identical or corresponding elements are designated by the same reference numerals, and duplicate explanations will be omitted as appropriate. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios and the like are not limited to those shown in the drawings.

[0017] FIG. 1 is a cross-sectional view showing an applicator member according to this embodiment. As shown in FIG. 1, the applicator member 1 according to this embodiment is an applicator container that contains liquid contents E and allows a user to apply the liquid contents E with bristles 2b. Below, an example will be described in which the applicator member 1 is a cosmetics container. In this case, the liquid contents E is, for example, a liquid cosmetic such as an eyeliner or lip liner, and the applicator member 1 is a liquid cosmetics container. The applicator member 1 has, for example, a rod shape extending in the axial direction D1. As an example, the applicator member 1 has a round rod shape.

[0018] In this specification, the terms "axis" and "axis line" refer to the center line of the applicator member 1 that extends along the longitudinal direction of the applicator member 1, and the term "axial direction" refers to the direction along the axis L of the applicator member 1 (for example, the longitudinal direction of the applicator member 1). In the following description, the direction in which the bristles 2b protrude from the applicator member 1 may be referred to as the "front," "front side," or "forward," and the opposite direction may be referred to as the "rear," "rear side," or "rear."

[0019] The "radial direction" refers to a direction toward or away from the axis L in a plane perpendicular to the axis L of the applicator member 1. The "radial outer direction" refers to a direction away from the axis L in the radial direction, and the "radial inner direction" refers to a direction toward the axis L in the radial direction. The "circumferential direction" refers to a direction along a ring centered on the axis L. However, these directions are for convenience of explanation and do not limit the position or orientation of an object.

[0020] The applicator member 1 has a container body 10 provided with a storage section 10b for storing the liquid content E therein, a brush 2 including a plurality of bristles 2b and to which the liquid content E is supplied, a brush holder 3 for holding the brush 2, a bellows member 4, a relay core 5, a cap 6, and a pressing member 7. The container body 10 has, for example, a front tube 11 for storing the brush holder 3 and the bellows member 4, a tail plug 12 for closing the end of the front tube 11 opposite the cap 6, and a rear tube 13 for storing a portion of the front tube 11 and extending rearward from the front tube 11.

[0021] The front tube 11 has a first portion 11b housed in the cap 6 and a second portion 11c housed in the rear tube 13. The first portion 11b has, for example, an inclined surface 11d that is inclined with respect to the axial direction D1 so that the diameter decreases toward the front, a protrusion 11f that protrudes from the inclined surface 11d, and an opening 11g from which the brush holder 3 protrudes. The protrusion 11f is the portion to which the cap 6 is attached.

[0022] The second portion 11c has a screw tube portion 11j with a male screw 11h formed on its outer periphery, and a cylindrical portion 11k with a storage portion 10b inside. A rear cylinder 13 is attached to the male screw 11h of the screw tube portion 11j. The storage portion 10b is formed inside the cylindrical portion 11k. The storage portion 10b stores the liquid content E to be supplied to the brush 2. The storage portion 10b stores a stirrer M that is movable and stirs the liquid content E by moving, along with the liquid content E.

[0023] The front tube 11 has a flange 11m located between the first portion 11b and the second portion 11c. The flange 11m protrudes radially outward from both the first portion 11b and the second portion 11c of the front tube 11. The flange 11m is exposed to the outside of the applicator member 1 when the cap 6 is attached to the front tube 11.

[0024] The rear tube 13 has an opening 13b into which the second portion 11c of the front tube 11 is inserted, and a female screw 13c extending rearward from the inside of the opening 13b. A male screw 11h of the front tube 11 inserted into the opening 13b is screwed into the female screw 13c. The front tube 11 is attached to the rear tube 13 by screwing the male screw 11h into the female screw 13c.

[0025] The cap 6 has a cylindrical outer cap 6b with a bottom, an inner cap 6c disposed inside the outer cap 6b, and a spring 6d that biases the inner cap 6c toward the front tube 11. The outer cap 6b has an opening 6f into which the first portion 11b of the front tube 11 is inserted, and an annular uneven portion 6g located inside and in front of the opening 6f. The annular uneven portion 6g engages with the convex portion 11f of the front tube 11 in the axial direction D1. The annular uneven portion 6g engages with the convex portion 11f in the axial direction D1, thereby attaching the cap 6 (outer cap 6b) to the front tube 11.

[0026] When the cap 6 is attached to the front tube 11, the front tube 11, the brush holder 3, and the brush 2 enter the interior of the inner cap 6c, and the inner surface of the inner cap 6c comes into contact with the outer surface of the front tube 11. This ensures airtightness for the front tube 11, the brush holder 3, and the brush 2. The inner cap 6c has a flange 6h that protrudes radially outward from the inner cap 6c.

[0027] The outer cap 6b has a bottom 6j on which a spring 6d is disposed. The spring 6d is disposed between the bottom 6j and a flange 6h of the inner cap 6c. The spring 6d biases the flange 6h toward (rearward of) the front tube 11. This causes the inner surface of the inner cap 6c to abut against the outer surface of the front tube 11, ensuring airtightness within the front tube 11.

[0028] The bellows member 4 is, for example, cylindrical. The relay core 5 passes through the interior of the bellows member 4 and extends from the storage section 10b to the interior of the brush 2. The relay core 5 extends in the axial direction D1. The front end of the relay core 5 protrudes from the bellows member 4 and is located inside the brush 2. The rear end of the relay core 5 is inserted into the storage section 10b. The relay core 5 delivers the liquid content E stored in the storage section 10b to the brush 2. The relay core 5 is made of, for example, acrylic resin.

[0029] Fig. 2 is an enlarged cross-sectional view of the brush 2, brush holder 3, bellows member 4, and relay core 5. Fig. 3 is a cross-sectional perspective view showing the brush 2, brush holder 3, bellows member 4, and relay core 5. As shown in Figs. 2 and 3, the brush holder 3 is cylindrical. The brush holder 3 has an opening 3b at the front end thereof through which the brush 2 protrudes.

[0030] The brush 2 has a tip end 2c that protrudes from an opening 3b located at one end of the brush holder 3, and a base end 2d that is the end opposite to the tip end 2c. The brush 2 includes a plurality of bristles 2b that extend from the base end 2d toward the opening 3b. The base end 2d is a flange 2f that expands in diameter relative to the rest of the brush 2.

[0031] FIG. 4(a) is a perspective view showing the brush holder 3. FIG. 4(b) is a perspective view of the brush holder 3 seen from behind. FIG. 5(a) is a cross-sectional perspective view showing the brush holder 3. FIG. 5(b) is a cross-sectional view showing the brush holder 3. As shown in FIGS. 4(a), 4(b), 5(a) and 5(b), the brush holder 3 has a stepped cylindrical shape.

[0032] The brush holder 3 has a first cylindrical portion 3c, a second cylindrical portion 3d, a third cylindrical portion 3f, and a fourth cylindrical portion 3g. The first cylindrical portion 3c, the second cylindrical portion 3d, the third cylindrical portion 3f, and the fourth cylindrical portion 3g are arranged in this order along the axial direction D1. The first cylindrical portion 3c has an opening 3b. When viewed along the axial direction D1, the opening 3b has a flattened shape having a major axis X1 and a minor axis X2.

[0033] For example, the opening 3b has an oval shape. The width of the opening 3b (the length in the minor axis direction D3, which will be described later) decreases from one side (the upper side in FIG. 4(a)) of the major axis direction D2 to the other side (the lower side in FIG. 4(a)). The major axis X1 extends in the major axis direction D2 intersecting with the axial direction D1, and the minor axis X2 extends in the minor axis direction D3 intersecting with the axial direction D1 and the major axis direction D2. When the opening 3b is viewed along the minor axis direction D3, the opening 3b is inclined obliquely rearward from one side to the other side of the major axis direction D2.

[0034] The first cylindrical portion 3c has, for example, an inclined surface 3h that is inclined with respect to the axial direction D1 so that the outer diameter of the first cylindrical portion 3c increases with increasing distance from the opening 3b, and an outer peripheral surface 3j that extends rearward from the inclined surface 3h. When cut along a plane perpendicular to the axial direction D1, the shape of the outer peripheral surface 3j is circular. When cut along a plane perpendicular to the axial direction D1, the cross section of the brush holder 3 changes from a circular shape to a flattened shape as it approaches the opening 3b.

[0035] The second cylindrical portion 3d and the third cylindrical portion 3f are cylindrical. The outer diameter of the second cylindrical portion 3d is larger than the outer diameter of the outer peripheral surface 3j. The outer diameter of the third cylindrical portion 3f is larger than the outer diameter of the second cylindrical portion 3d. The fourth cylindrical portion 3g has, for example, a first outer surface 3k extending rearward from the third cylindrical portion 3f, a second outer surface 3m extending rearward from the first outer surface 3k, and a third outer surface 3p extending in the circumferential direction D4 at the rear end of the second outer surface 3m.

[0036] The outer diameters of the first outer surface 3k and the second outer surface 3m increase toward the rear. The outer diameter of the third outer surface 3p is constant. The brush holder 3 has a recess 3q extending forward from the rear end of the brush holder 3. The fourth cylindrical portion 3g has a linear protrusion 3r between the first outer surface 3k and the second outer surface 3m.

[0037] The recess 3q and a portion of the protrusion 3r are aligned along the axial direction D1. The protrusion 3r is, for example, curved. The protrusion 3r is located at the frontmost position where it is aligned with the recess 3q along the axial direction D1, and extends obliquely rearward in the circumferential direction D4 as it moves away from the recess 3q.

[0038] The brush holder 3 has an inner surface 3z. The inner surface 3z includes, for example, a first inner surface 3s, a second inner surface 3t, a third inner surface 3v, a fourth inner surface 3w, and an annular uneven portion 3x. The first inner surface 3s, the second inner surface 3t, the third inner surface 3v, the fourth inner surface 3w, and the annular uneven portion 3x are aligned in this order along the axial direction D1. The first inner surface 3s extends rearward from the opening 3b.

[0039] When cut along a plane perpendicular to the axial direction D1, the shape of the first inner surface 3s becomes flatter as it approaches the opening 3b and becomes more circular as it moves away from the opening 3b. When cut along a plane perpendicular to the axial direction D1, the shapes of the second inner surface 3t and the third inner surface 3v are circular. The inner diameter of the third inner surface 3v is larger than the inner diameter of the second inner surface 3t. The annular uneven portion 3x is formed behind the fourth inner surface 3w inside the brush holder 3. A pressing member 7, described later, engages with the annular uneven portion 3x in the axial direction D1.

[0040] The brush holder 3 has a step portion 3y that protrudes from the inner surface 3z of the brush holder 3. The step portion 3y is formed between the third inner surface 3v and the fourth inner surface 3w. The step portion 3y is located at the front end of the fourth inner surface 3w and protrudes radially inward from the fourth inner surface 3w. The step portion 3y has an abutment surface 3y1 that abuts against the flange portion 2f of the brush 2 (see Figure 2 or 3). The step portion 3y is constituted by the abutment surface 3y1 and the third inner surface 3v.

[0041] When cut along a plane extending in the axial direction D1 and the longitudinal direction D2, the step portion 3y (abutment surface 3y1) is inclined with respect to both the axial direction D1 and the longitudinal direction D2. The step portion 3y is inclined toward the same side as the opening 3b. The abutment surface 3y1 is, for example, curved. The abutment surface 3y1 is located at the frontmost position where it is aligned with the recessed portion 3q along the axial direction D1, and extends obliquely rearward in the circumferential direction D4 as it moves away from the recessed portion 3q.

[0042] A brush 2 is inserted into the brush holder 3. The shape of the brush 2 when not inserted into the brush holder 3 is different from the shape of the brush 2 when inserted into the brush holder 3. Fig. 6 is a perspective view showing the brush 2 when not inserted into the brush holder 3.

[0043] As shown in Figure 6, the brush 2 has a conical shape when not inserted into the brush holder 3. The brush 2 is formed by bundling a plurality of bristles 2b. The bristles 2b are made of, for example, PBT (polybutylene terephthalate). However, the bristles 2b may also be made of nylon, and the material of the bristles 2b is not particularly limited.

[0044] When not inserted into the brush holder 3, the cross section of the brush 2 taken along a plane perpendicular to the axial direction D1 is circular. The flange 2f functions as a holder that holds the bristles 2b. The flange 2f is the portion where the bristles 2b are packed together.

[0045] For example, in the flange 2f, the plurality of brush bristles 2b are fixed by welding. However, the plurality of brush bristles 2b may also be fixed by adhesive, and the means for fixing the brush bristles 2b is not particularly limited. The flange 2f is, for example, disc-shaped. The flange 2f has a surface 2g facing rearward and a hole 2h extending forward from the surface 2g. The aforementioned relay core 5 is inserted into the hole 2h. The hole 2h, for example, penetrates the flange 2f in the axial direction D1.

[0046] When the brush 2 is inserted into the brush holder 3, the outer diameter of the brush 2 (plurality of bristles 2b) changes to match the shape of the inner surface 3z of the brush holder 3. The shape of the brush 2 inserted into the brush holder 3 becomes flatter as the brush 2 passes through the inner surface 3z and approaches the opening 3b. The shape of the bristles 2b protruding from the opening 3b is flat with a major axis and a minor axis, similar to the shape of the opening 3b. The shape of the brush 2 inserted into the brush holder 3 will be described in detail later.

[0047] Fig. 7 is a side view showing the bellows member 4 and the pressing member 7. Fig. 8(a) is a perspective view of the bellows member 4 and the pressing member 7 seen from the front. Fig. 8(b) is a perspective view of the bellows member 4 and the pressing member 7 seen from the rear. The bellows member 4 adjusts the amount of liquid content E supplied to the brush 2.

[0048] As shown in Figures 2, 7, 8(a) and 8(b), the bellows member 4 is arranged to surround the relay core 5. The bellows member 4 is made of, for example, PP (polypropylene). The bellows member 4 has a plurality of grooves 4b that hold the liquid contents E. The plurality of grooves 4b are aligned along the axial direction D1.

[0049] The bellows member 4 has an expanded diameter portion 4c that projects radially outward and a protruding portion 4d that projects rearward from the expanded diameter portion 4c. The expanded diameter portion 4c engages in the axial direction D1 with an annular recess 11q formed on the inner surface 11p of the front tube 11. The bellows member 4 has a plurality of (for example, two) protruding portions 4d.

[0050] The protruding portion 4d has a first portion 4f extending rearward from the expanded diameter portion 4c and a second portion 4g protruding radially inward from the rear end of the first portion 4f. The second portion 4g is a portion that holds the relay core 5. The second portions 4g of the multiple protruding portions 4d protrude in directions approaching each other. The multiple second portions 4g bite into the relay core 5, thereby holding the relay core 5.

[0051] For example, a flat surface 4h facing forward is formed on the end of the bellows member 4 opposite (on the front side) from the protruding portion 4d. The pressing member 7 is interposed between the bellows member 4 and the brush 2. The pressing member 7 is housed inside the container body 10 (front tube 11) in a state of contact with the flat surface 4h.

[0052] For example, the pressing member 7 is a separate part (a separate body) from the bellows member 4. However, the pressing member 7 may be integrated with the bellows member 4. For example, the bellows member 4 and the pressing member 7 may be integrally molded, or the bellows member 4 may be the pressing member. In this case, the number of parts of the applying member 1 can be reduced.

[0053] The pressing member 7 presses the brush 2 toward the opening 3b. In other words, the pressing member 7 presses the brush 2 forward. The pressing member 7 is cylindrical. The pressing member 7 has an annular protrusion 7b formed on an outer peripheral surface 7c of the pressing member 7, and a protrusion 7d protruding from the outer peripheral surface 7c to one side in the longitudinal direction D2 (the upper side in FIG. 8(a)). The annular protrusion 7b engages with the annular concave-convex portion 3x of the brush holder 3 described above in the axial direction D1, and the protrusion 7d enters the recess 3q of the brush holder 3 along the axial direction D1. As a result, the pressing member 7 engages with the brush holder 3 in the axial direction D1 and the circumferential direction D4.

[0054] The pressing member 7 has an inclined portion 7f that is inclined with respect to a plane perpendicular to the axis L. The inclined portion 7f is, for example, an inclined surface that inclines so as to protrude forward toward one side in the longitudinal direction D2. For example, the inclined portion 7f is a flat surface. The position of the inclined portion 7f in the axial direction D1 varies depending on the position of the inclined portion 7f in the circumferential direction D4. Specifically, the position of the inclined portion 7f in the axial direction D1 is the most protruding position at one end of the inclined portion 7f in the longitudinal direction D2, and the most recessed position at the other end of the inclined portion 7f in the longitudinal direction D2.

[0055] 2 and 3, when the pressing member 7 is engaged with the brush holder 3, the inclined portion 7f inclines the base end portion 2d of the brush 2 with respect to a plane perpendicular to the axial direction D1. The inclined portion 7f presses the base end portion 2d, causing the base end portion 2d to incline with respect to a plane perpendicular to the axial direction D1. When the base end portion 2d is inclined, the base end portion 2d is pressed unevenly, causing the entire brush 2 to incline.

[0056] More specifically, the base end 2d is inclined so that one side in the major axis direction D2 protrudes further forward than the other side. Accordingly, one side of the tip end 2c of the brush 2 in the major axis direction D2 protrudes further forward than the other side, forming an inclined portion 2j at the tip end 2c. When viewed along the minor axis direction D3, the inclined portion 2j extends in a direction inclined with respect to both the axial direction D1 and the major axis direction D2. When the pressing member 7 is engaged with the brush holder 3, the flange portion 2f of the brush 2 is sandwiched between the step portion 3y and the inclined portion 7f of the brush holder 3. Therefore, the inclined state of the brush 2 is maintained.

[0057] Next, we will explain the movement of each part when assembling the brush 2 and pressing member 7 to the brush holder 3. First, when the brush 2 is inserted into the brush holder 3 from the rear, the conical brush 2 changes to a flattened shape as it approaches the opening 3b. Then, the flattened brush 2 protrudes from the opening 3b.

[0058] When the pressing member 7 is assembled to the brush holder 3 in the above state, the inclined portion 7f biases the base end portion 2d of the brush 2, causing one side of the brush 2 to protrude more in the longitudinal axis direction D2 than the other side. Then, the flange portion 2f is sandwiched between the inclined portion 7f and the step portion 3y, and the pressing member 7 engages with the brush holder 3, causing the brush 2 to tilt as described above, and the assembly is completed with the inclined portion 2j formed at the tip end portion 2c.

[0059] Next, we will explain the effects obtained from the applicator member 1 according to this embodiment. The applicator member 1 has a brush 2 including a plurality of bristles 2b, and the brush 2 has a tip end 2c that protrudes from an opening 3b located at one end of a cylindrical brush holder 3. The brush 2 has a base end 2d, which is the end opposite to the tip end 2c, and the plurality of bristles 2b extend from the base end 2d toward the opening 3b.

[0060] In a conventional applicator member, as shown in FIG. 11 , the inclined portion 102f at the end of the brush 102, which is made up of a bundle of bristles 102b, is formed by cutting the tip 102c of the brush 102 with a blade after the brush 102 is manufactured. When the inclined portion 102f is formed by cutting the brush 102, the bundle of bristles 102b is cut at an angle, which can cause a problem of variation in the thickness T of the tip of the bristles 102b. When the thickness T of the tip of the bristles 102b varies, the line formed during application may become thicker, resulting in a poor application finish. For example, the line of applied cosmetic may become thicker, resulting in a poor makeup finish.

[0061] In contrast, as shown in Figures 2 and 3, the applicator 1 has an inclined portion 7f, which inclines the base end 2d relative to a plane perpendicular to the axial direction D1. The inclined base end 2d of the brush 2 from which the bristles 2b extend results in the inclined tip ends 2c of the bristles 2b, making it possible to form the inclined portion 2j without cutting. This eliminates the need for a step of cutting the brush 2, thereby reducing the cost of manufacturing the applicator 1. Furthermore, by not cutting the brush 2, it is possible to avoid variations in the thickness of the tip ends 2c of the bristles 2b. This prevents poor application finish, for example, poor makeup finish.

[0062] In this embodiment, the applicator 1 includes a pressing member 7 that presses the brush 2 toward the opening 3b, and the pressing member 7 has an inclined portion 7f. In this case, the inclined portion 7f of the pressing member 7 presses the base end 2d of the brush 2, thereby inclining the tip ends 2c of the multiple bristles 2b. Therefore, the inclined portion 2j can be formed by the pressing member 7 pressing the brush 2, making it easy to assemble the applicator 1.

[0063] In this embodiment, the base end 2d is a flange 2f that expands in diameter relative to the remaining portion of the brush 2. The brush holder 3 has a step 3y that protrudes from the inner surface 3z of the brush holder 3. The flange 2f is sandwiched between the step 3y and the inclined portion 7f. In this case, because the flange 2f, which is the base end 2d of the brush 2, is sandwiched between the step 3y and the inclined portion 7f of the brush holder 3, the inclined state of the brush 2 can be more reliably maintained.

[0064] In this embodiment, when viewed along the axial direction D1, the opening 3b has a flat shape with a major axis X1 and a minor axis X2. In this case, the tip 2c of the brush 2 protruding from the opening 3b has a flat shape with a major axis and a minor axis. Therefore, by bringing the flat tip 2c of the brush 2 into contact with the application target, it is possible to freely draw thick and thin lines on the application target. This improves the quality of application by the bristles 2b.

[0065] In this embodiment, the applicator 1 includes a container body 10 having a storage section 10b therein for storing the liquid content E to be supplied to the brush 2, and a bellows member 4 for adjusting the amount of the liquid content E to be supplied to the brush 2. As described above, the bellows member 4 may also be a pressing member. In this case, the bellows member 4 for adjusting the amount of the liquid content E to the brush 2 can be effectively used as a pressing member.

[0066] Next, a brush holder 23 according to a modified example will be described with reference to Figures 9(a), 9(b), and 10. Figure 9(a) is a perspective view showing the brush holder 23. Figure 9(b) is a cross-sectional view of the brush holder 23 taken along a plane extending in the axial direction D1 and the minor axis direction D3. Figure 10 is a cross-sectional view of the brush holder 23 taken along a plane perpendicular to the axial direction D1.

[0067] The brush holder 23 can be used in place of the brush holder 3 described above. Part of the configuration of the brush holder 23 is the same as part of the configuration of the brush holder 3 described above. For example, the outer shape of the brush holder 23 is the same as the outer shape of the brush holder 3. Therefore, in the following, parts that overlap with the above description will be denoted by the same reference numerals and will be omitted as appropriate.

[0068] The brush holder 23 does not have a stepped portion 3y. The brush holder 23 has ribs 23b protruding from an inner surface 3z of the brush holder 23. The ribs 23b extend in the axial direction D1 inside the brush holder 23. The ribs 23b bite into the brush 2 moving inside the brush holder 23 toward the opening 3b. The brush holder 23 has, for example, a plurality of ribs 23b. As an example, four ribs 23b are arranged at equal intervals along the circumferential direction D4. When the brush holder 23 is cut along a plane perpendicular to the axial direction D1, the cross-sectional shape of the ribs 23b is, for example, V-shaped. However, the cross-sectional shape may be trapezoidal, rectangular, or U-shaped, and is not particularly limited.

[0069] As described above, the brush holder 23 according to the modified example has a rib 23b that protrudes from the inner surface 3z of the brush holder 23 and bites into the brush 2 that moves inside the brush holder 23 toward the opening 3b. In this case, the rib 23b can bite into the brush 2 when the brush 2 is assembled inside the brush holder 23. Therefore, the assembled brush 2 can be prevented from moving toward the opening 3b. In addition, the step portion 3y described above can be eliminated. Furthermore, it is possible to assemble a brush 2 that does not have a flange portion 2f.

[0070] The above describes embodiments and modifications of the application member according to the present disclosure. However, the application member according to the present disclosure is not limited to the above-described embodiments or modifications, and may be further modified within the scope of the gist described in the claims. In other words, the function, shape, size, material, number, and arrangement of each part of the application member can be appropriately changed within the scope of the above-described gist.

[0071] For example, in the above-described embodiment, an example was described in which the liquid content E was a cosmetic. However, the liquid content may be something other than a cosmetic. For example, the liquid content may be ink or India ink, or the contents of a writing implement or stationery. The application member may be a container other than a cosmetic container, such as a writing implement or stationery. Furthermore, the application member may be a brush unit that does not have a liquid content, or may be at least a part of a cartridge.

[0072] In the above-described embodiment, the applicator 1 has been described in which the pressing member 7 interposed between the brush 2 and the bellows member 4 has the inclined portion 7f. However, for example, a component other than the pressing member 7, such as the bellows member 4, may have the inclined portion. Also, the applicator may not have the pressing member 7. Furthermore, the brush holder 3 may have the inclined portion. In this case, a groove corresponding to the stepped portion 3y may be formed on the inner surface 3z of the brush holder 3, and the inner surface of this groove may be the inclined portion. In this way, it is possible to appropriately change which component of the applicator has the inclined portion. [Explanation of symbols]
