Description

Technical Field

[0001] The present disclosure relates to an applicator and an application member for applying a coating material to a coated portion.

Background Art

[0002] Patent Document 1 describes a cosmetic applicator including an applicator body and a support portion to which the applicator body is attached at an end. The outer shape of the tip of the applicator body is spherical. The applicator body has a base portion that is fitted into a large-diameter end portion where the diameter expands in the support portion. The support portion has a shaft body extending from the large-diameter end portion, an outer cylinder into which the shaft body is inserted, and a rotation mechanism for rotating the applicator body and the shaft body with respect to the outer cylinder. Inside the outer cylinder, a spring and a sponge are provided as elastic bodies that resist the entry of the shaft body.

[0003] When the applicator body slides on the coated surface, a pressing force is applied to the shaft body, and the shaft body is pushed into the inside of the outer cylinder while rotating. When the applicator body is separated from the coated surface, the shaft body returns to its original position by the elastic force of the spring and the sponge. When applying a cosmetic with the applicator body, the applicator body moves on the coated surface while rotating with respect to the outer cylinder.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Incidentally, when the applicator is applied to the surface to be coated, it elastically deforms and indents. In order to apply the coating material smoothly with a gradient, it is necessary to give the applicator high elasticity and to indent the entire applicator during application. The aforementioned cosmetic applicator has a rotating mechanism that rotates the applicator and shaft relative to the outer cylinder, and a spring and sponge as elastic materials, resulting in a large number of parts and a complex structure. Therefore, it is necessary to simplify the structure.

[0006] The present disclosure aims to provide a coating material and a coating member that can be made to have high elasticity, allowing the entire coating material to be indented, and that can be constructed simply. [Means for solving the problem]

[0007] (1) The coating body according to the present disclosure applies a coating material to a part to be coated. The coating body comprises a cylindrical portion fixed to a holding member that holds the coating body, and a protruding portion that protrudes from the cylindrical portion, is hollow, and is made of an elastic material. The protruding portion has a curved portion that protrudes from the cylindrical portion, and an enlarged portion that is located between the cylindrical portion and the curved portion and is a portion that expands in diameter from the cylindrical portion toward the curved portion.

[0008] This coating body comprises a cylindrical portion and a protruding portion, and the coating body is held by the holding member by the cylindrical portion being fixed to the holding member. The protruding portion is made of an elastic body that protrudes from the cylindrical portion and is hollow. The protruding portion has a curved surface portion and an enlarged diameter portion located between the cylindrical portion and the curved surface portion, and the enlarged diameter portion expands in diameter from the cylindrical portion toward the curved surface portion. Therefore, the curved surface portion can be given high elasticity, and the structure can be simplified as springs, sponges, and rotating mechanisms are not required. When applying the coating by applying the curved surface portion to the surface to be coated, the enlarged diameter portion can be used to create an overall indentation in the curved surface portion. Therefore, by applying the coating material to the surface to be coated, the coating material adhering to the curved surface portion can be applied smoothly with a blurred gradient.

[0009] (2) In (1) above, the curved portion may have a portion where the thickness of the coating in the curved portion is greater than the thickness of the coating in the enlarged diameter portion. In this case, having a portion of the curved portion that is thicker than the enlarged diameter portion prevents the curved portion from being locally concave and allows the curved portion to be concave evenly.

[0010] (3) In (1) or (2) above, the thickness of the coating on the curved portion may increase as it moves away from the enlarged diameter portion. In this case, it is possible to prevent the curved portion from breaking at a specific point and to make the curved portion evenly and uniformly concave.

[0011] (4) The coating member according to the present disclosure comprises the coating body described above and a holding member that fixes the cylindrical portion of the coating body and holds the coating body. Since this coating member comprises the coating body described above, it provides the same effects as the coating body described above.

[0012] (5) In (4) above, the holding member may have an internal space that communicates with the outside of the coating member and the inside of the curved portion. In this case, when the curved portion is applied to the portion to be coated, the air inside the curved portion can be released to the outside of the coating member through the internal space of the holding member. Therefore, the elastic force of the curved portion can be further increased, making it easier to indent the curved portion. [Effects of the Invention]

[0013] According to this disclosure, it is possible to give the coated material high elasticity and create an overall indentation, while also simplifying the structure. [Brief explanation of the drawing]

[0014] [Figure 1] Figure 1 is a cross-sectional view showing a coating member according to an embodiment. [Figure 2] Figure 2 is a cross-sectional view showing the coating body and holding member of the coating member shown in Figure 1. [Figure 3] Figure 3 is a perspective view showing the retaining member of Figure 2. [Figure 4] Figure 4 is a perspective view showing the coated material from Figure 2. [Figure 5] FIG. 5 is a side view showing the coating body of FIG. 2. [Figure 6] FIG. 6 is a cross-sectional view showing the coating body of FIG. 2.

Embodiments for Carrying out the Invention

[0015] Hereinafter, embodiments of the coating body and the coating member according to the present disclosure will be described. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant descriptions will be omitted as appropriate. The drawings may be drawn with some parts simplified or exaggerated for ease of understanding, and the dimensional ratios and the like are not limited to those described in the drawings.

[0016] FIG. 1 is a cross-sectional view showing a coating member 1 including a coating body 10 according to the present embodiment. As shown in FIG. 1, the coating member 1 is a coating container that houses a coating material M and allows a user to apply the coating material M with the coating body 10. The coating material M is, for example, in a solid state. However, the coating material M may be in a semi-solid state, a soft state, or a gel state.

[0017] As an example, the coating material M is a cosmetic, and the coating member 1 is a cosmetic container. The coating body 10 applies the coating material M to the coated portion. The "coated portion" refers to an object to which the coating material is applied. The "coated portion" is, for example, the skin, eyebrows, hair, or paper of the user of the coating member 1.

[0018] In the coating member 1, some parts are cylindrical. In this specification, the "axis" and the "axis line" indicate the center line extending in the longitudinal direction of the coating member 1 in the coating member 1, and the "axis line direction" indicates the direction along the axis line L of the coating member 1. For example, in the coating member 1, in the assembled state of the parts, the directions in which the axis lines L of the plurality of cylindrical parts extend coincide with each other. Hereinafter, the direction in which this axis line L extends is referred to as the axis line direction D. The coating member 1 is, for example, in a rod shape extending in the axis line direction D. As an example, the coating member 1 is in a round rod shape.

[0019] The coating member 1 includes a coating body 10 and a container body 2 that holds the coating body 10. The container body 2 includes an outer cylinder 2A that constitutes the outer surface of the container body 2 and a holding member 3 that holds the coating body 10. For example, the outer cylinder 2A has a bottomed cylindrical shape (e.g., a bottomed circular cylindrical shape). A part of the holding member 3 is accommodated inside the outer cylinder 2A.

[0020] A part of the coating body 10 protrudes from the holding member 3. Hereinafter, the direction in which the coating body 10 protrudes from the holding member 3 may be referred to as "front", "front side" or "forward", and the opposite direction may be referred to as "rear", "rear side" or "backward". The "radial direction" indicates the direction toward the axis L and the direction away from the axis L in a plane orthogonal to the axis L of the coating member 1. "Radially outward" indicates the direction away from the axis L in the radial direction, and "radially inward" indicates the direction toward the axis L in the radial direction. The "circumferential direction" indicates the direction along a ring centered on the axis L. However, these directions are for the convenience of explanation and do not limit the position or orientation of the object.

[0021] The holding member 3 includes a middle cylinder 4 having a portion accommodated in the outer cylinder 2A and an inner cylinder 5 located inside the middle cylinder 4. The middle cylinder 4 is engaged with the outer cylinder 2A in the axial direction D. The inner cylinder 5 is located on the front side of the middle cylinder 4. The inner cylinder 5 is engaged with the middle cylinder 4 in the axial direction D inside the middle cylinder 4. The holding member 3 holds the coating body 10 by sandwiching the coating body 10 between the middle cylinder 4 and the inner cylinder 5.

[0022] The coating member 1 has a cap 6 that covers the coating body 10 and is attached to the container body 2. The cap 6 includes a cylindrical portion 6A and a tail plug 6B. The tail plug 6B closes one end of the cylindrical portion 6A in the axial direction D. The tail plug 6B has a bottomed cylindrical shape (e.g., a bottomed circular cylindrical shape). The cap 6 is detachable from the container body 2 (e.g., the middle cylinder 4). The cap 6 is attached to the container body 2 when the cylindrical portion 6A is engaged with the middle cylinder 4 in the axial direction D.

[0023] The cap 6 has a coating material storage section 7 located inside the cylindrical section 6A, and a spring 8 that biases the coating material storage section 7 backward. The coating material storage section 7 is bottomed cylindrical (for example, bottomed cylindrical). The coating material M is filled inside the coating material storage section 7. The coating material storage section 7 is movable in the axial direction D inside the cylindrical section 6A. When the cap 6 is attached to the container body 2, the coating body 10 enters the inside of the coating material storage section 7 and the coating body 10 comes into contact with the coating material M. As a result, the coating material M adheres to the coating body 10.

[0024] The spring 8 is positioned between the tail plug 6B and the coating material storage section 7. The spring 8 biases the coating material storage section 7 backward when the cap 6 is attached to the container body 2. For example, the coating material storage section 7 has a reduced diameter section at the end on the tail plug 6B side, and one end of the spring 8 is wrapped around this reduced diameter section.

[0025] The spring 8, together with the coating material storage section 7, biases the coating material M stored in the coating material storage section 7 toward the coating body 10. Therefore, even if the amount of coating material M in the coating material storage section 7 decreases, the coating material M can be reliably attached to the coating body 10, thus allowing the entire amount of coating material M stored in the coating material storage section 7 to be used.

[0026] Figure 2 is a cross-sectional view showing the coating body 10 and the inner cylinder 5. As shown in Figures 1 and 2, the inner cylinder 5 is part of the holding member 3. The coating body 10 has a cylindrical portion 11A that is fixed to the holding member 3 (inner cylinder 5) that holds the coating body 10, and a protruding portion 11B that protrudes from the cylindrical portion 11A.

[0027] Figure 3 is a perspective view showing the inner cylinder 5. As shown in Figures 1, 2, and 3, the inner cylinder 5 has an insertion portion 5b that is inserted into the cylindrical portion 11A, and a projection portion 5g that protrudes from the insertion portion 5b in the direction opposite to the coating body 10. The coating body 10 is made of a material that is non-permeable and non-penetrating. That is, the coating body 10 is made of a material that does not allow the coating material M to pass through.

[0028] The coating body 10 is made of, for example, an elastic material. For example, the coating body 10 is made of nitrile rubber (NBR). In this case, the cost of the material for the coating body 10 can be reduced, and a material that is compatible with the coating material M can be used. However, depending on the material of the coating material M, the coating body 10 may be made of a material other than NBR, such as silicone rubber.

[0029] The radial length of the insertion portion 5b is greater than the radial length of the projection portion 5g. The projection portion 5g has, for example, an annular projection 5h that engages with the inner surface of the inner cylinder 4 in the axial direction D. The insertion portion 5b engages with the inner surface of the cylindrical portion 11A in a manner that is immovable in both the axial and circumferential directions. The insertion portion 5b has a plurality of projections 5b1 and a plurality of recesses 5b2 arranged along the circumferential direction, with the projections 5b1 and recesses 5b2 alternating along the circumferential direction. The plurality of projections 5b1 abut against the inner surface of the cylindrical portion 11A. As a result, the inner cylinder 5 engages with the coating body 10 in the circumferential direction.

[0030] The insertion portion 5b has an annular recess 5c located at the rear end of the protrusion 5b1, an annular protrusion 5d protruding from the bottom surface of the annular recess 5c, and an annular protrusion 5f located behind the annular recess 5c. The inner surface of the cylindrical portion 11A (the annular protrusion 11b described later) fits into the annular recess 5c, and the annular protrusion 5d fits into the inner surface of the cylindrical portion 11A that has entered the annular recess 5c.

[0031] The annular recess 5c is shaped such that when the cylindrical portion 11A is inserted into it, the annular projection 5d penetrates its inner surface. The annular recess 5c is located between the projection 5b1 and the annular projection 5f, and the height of the annular projection 5d relative to the bottom surface of the annular recess 5c increases towards the rear. That is, the radial length of the annular projection 5d increases towards the rear. For example, by sharpening the radially outer end of the annular projection 5d, the annular projection 5d can be penetrated into the inner surface of the cylindrical portion 11A that has entered the annular recess 5c.

[0032] The coating body 10 will be described in more detail. Figure 4 is a perspective view showing the coating body 10. Figure 5 is a side view showing the coating body 10. Figure 6 is a cross-sectional view taken along line AA of Figure 5. As shown in Figures 4, 5, and 6, the protrusion 11B of the coating body 10 is hollow. The protrusion 11B is made of an elastic material. The above describes an example in which the coating body 10 is made of an elastic material. However, only the protrusion 11B of the coating body 10 may be made of an elastic material.

[0033] The protruding portion 11B has a curved surface portion 13 that protrudes from the cylindrical portion 11A and an enlarged diameter portion 12 located between the cylindrical portion 11A and the curved surface portion 13. The enlarged diameter portion 12 is the part that expands in diameter from the cylindrical portion 11A toward the curved surface portion 13. That is, the radial length of the enlarged diameter portion 12 increases from the cylindrical portion 11A toward the curved surface portion 13.

[0034] The curved portion 13 is the part to which the coating material M adheres and the part that contacts the area to be coated. When the curved portion 13 comes into contact with the area to be coated, it indents and applies the coating material M to the area to be coated. The curved portion 13 is non-penetrating. Therefore, the coating material M does not penetrate the curved portion 13, and the coating material M adheres thinly to the curved portion 13, allowing the coating material M to be applied to the area to be coated in a blurred manner. Thus, by adjusting the pressure of the curved portion 13 against the area to be coated, the coating material M can be applied while creating a gradient.

[0035] The enlarged diameter portion 12 has, for example, a first curved surface 12b extending from the cylindrical portion 11A toward the curved surface portion 13, a second curved surface 12d extending from the curved surface portion 13 toward the cylindrical portion 11A, and an inclined surface 12c extending from the first curved surface 12b toward the second curved surface 12d. The first curved surface 12b is curved so as to become concave from the inclined surface 12c toward the cylindrical portion 11A. The second curved surface 12d is curved so as to become bulging from the inclined surface 12c toward the curved surface portion 13. Because the enlarged diameter portion 12 has the first curved surface 12b and the second curved surface 12d, the curved surface portion 13 can be more effectively concave when the coating material M is applied.

[0036] The curved portion 13 has, for example, a cylindrical portion 13b extending forward from the enlarged diameter portion 12, a curved portion 13c that curves so as to gradually decrease in diameter as it extends forward from the cylindrical portion 13b, and a apex portion 13d located at the end of the curved portion 13c opposite to the cylindrical portion 13b. The cylindrical portion 13b is cylindrical, and the curved portion 13c is hemispherical. The apex portion 13d may have a flat surface extending along a plane perpendicular to the axis L.

[0037] As shown in Figures 1, 2, and 6, the cylindrical portion 11A has an outer surface 11f facing the inner surface of the inner cylinder 4. The cylindrical portion 11A has a curved portion 11h at the rear end of the outer surface 11f that gradually decreases in diameter towards the rear. The cylindrical portion 11A has an inner surface 11d facing the outer surface of the inner cylinder 5. The cylindrical portion 11A has an annular projection 11b on its inner surface 11d that engages with the inner cylinder 5 in the axial direction D.

[0038] The annular projection 11b protrudes radially inward from the inner surface 11d of the cylindrical portion 11A. In a cross-section when cut along a plane containing the axis L, the annular projection 11b is trapezoidal. The annular projection 11b has a first inclined surface 11b2 that protrudes radially inward from the rear end of the cylindrical portion 11A, a top surface 11b1 that extends from the first inclined surface 11b2 along the axial direction D and the circumferential direction, and a second inclined surface 11b3 that recesses from the top surface 11b1 toward the enlarged diameter portion 12. The annular projection 5d of the inner cylinder 5 enters radially outward into the annular projection 11b (top surface 11b1), thereby pressing the cylindrical portion 11A against the inner surface of the middle cylinder 4 (radially outward). This makes it possible to firmly sandwich the cylindrical portion 11A between the middle cylinder 4 and the inner cylinder 5.

[0039] The thickness of each part of the coated body 10 will now be described. The curved portion 13 has a portion where the thickness of the coated body 10 is greater than the thickness of the coated body 10 in the enlarged diameter portion 12. For example, the thickness of the coated body 10 in the curved portion 13 increases as it moves away from the enlarged diameter portion 12. That is, the thickness of the curved portion 13 increases from the cylindrical portion 13b toward the curved portion 13c, and increases from the curved portion 13c toward the top portion 13d.

[0040] For example, the thickness of the enlarged diameter portion 12 is thinner than the thickness of the parts of the coated body 10 other than the enlarged diameter portion 12. The thickness of the enlarged diameter portion 12 is constant. The thickness of the cylindrical portion 11A is thicker than the thickness of the enlarged diameter portion 12. The maximum thickness of the annular projection 11b of the cylindrical portion 11A (the thickness of the annular projection 11b at the top surface 11b1) is thicker than the thickness of the parts of the coated body 10 other than the annular projection 11b. In other words, the annular projection 11b of the cylindrical portion 11A is the thickest part of the coated body 10.

[0041] As an example, the maximum thickness of the annular projection 11b is 0.8 mm, the thickness of the cylindrical portion 11A other than the annular projection 11b is 0.6 mm, the thickness of the enlarged diameter portion 12 is 0.5 mm, and the thickness of the top 13d of the curved surface portion 13 is 0.6 mm. Furthermore, the thickness of the coated body 10 gradually increases from 0.5 mm to 0.6 mm as it moves from the enlarged diameter portion 12 towards the top 13d. The above describes an example of the thickness of the coated body 10. However, the thickness of the coated body 10 is not limited to the above values ​​and can be changed as appropriate.

[0042] The holding member 3 has an internal space 3A that communicates with the outside of the coating member 1 and the inside of the curved portion 13. In this embodiment, the internal space 3A is formed inside the inner cylinder 5 and inside the middle cylinder 4. The internal space 3A communicates with the outside of the coating member 1 through a gap S formed between, for example, the container body 2 (outer cylinder 2A) and the middle cylinder 4. As a result, when the curved portion 13 is pressed by coating or the like, the air inside the curved portion 13 is discharged to the outside of the coating member 1 through the internal space 3A and the gap S.

[0043] Next, the effects and advantages obtained from the coating member 1 according to this embodiment will be described. The coating body 10 comprises a cylindrical portion 11A and a protruding portion 11B, and the coating body 10 is held by the holding member 3 by fixing the cylindrical portion 11A to the holding member 3. The protruding portion 11B is made of an elastic body that protrudes from the cylindrical portion 11A and is hollow. The protruding portion 11B has a curved surface portion 13 and an enlarged diameter portion 12 located between the cylindrical portion 11A and the curved surface portion 13, and the enlarged diameter portion 12 expands in diameter from the cylindrical portion 11A toward the curved surface portion 13. Therefore, the curved surface portion 13 can be given high elasticity, and it is not necessary to provide a spring, sponge and rotating mechanism in the container body 2, so the structure can be simplified.

[0044] When applying the coating by bringing the curved portion 13 into contact with the area to be coated, the enlarged diameter portion 12 can cause the entire curved portion 13 to be recessed. Therefore, by bringing the curved portion 13 into contact with the area to be coated, the coating material M adhering to the curved portion 13 can be applied smoothly with a blurred gradient.

[0045] In this embodiment, the curved portion 13 has a portion where the thickness of the coating 10 is greater than the thickness of the coating 10 in the enlarged diameter portion 12. In this embodiment, the thickness of the top portion 13d is greater than the thickness of the enlarged diameter portion 12. In this case, because the curved portion 13 has a portion that is thicker than the enlarged diameter portion 12, it is possible to prevent the curved portion 13 from being locally concave and to concave the curved portion 13 evenly.

[0046] In this embodiment, the thickness of the coating 10 on the curved portion 13 increases as it moves away from the enlarged diameter portion 12. In this case, it is possible to prevent the curved portion 13 from breaking at a specific point and to create a uniform, overall indentation on the curved portion 13.

[0047] The coating member 1 according to this embodiment comprises a coating body 10 and a holding member 3 that fixes the cylindrical portion 11A of the coating body 10 and holds the coating body 10. Since the coating member 1 comprises the coating body 10 described above, it provides the same effects and advantages as the coating body 10 described above.

[0048] In this embodiment, the holding member 3 has an internal space 3A that communicates with the outside of the coating member 1 and the inside of the curved portion 13. In this case, when the curved portion 13 is applied to the part to be coated, the air inside the curved portion 13 can be released to the outside of the coating member 1 through the internal space 3A of the holding member 3. Therefore, the elastic force of the curved portion 13 can be further increased, making it easier to indent the curved portion 13.

[0049] Embodiments of the coating body and coating member according to the present disclosure have been described above. However, the coating body and coating member according to the present disclosure are not limited to the embodiments described above, and may be modified within the scope of the gist described in the claims. That is, the shape, size, material, number, and arrangement of each part of the coating body and coating member according to the present disclosure can be appropriately changed within the scope of the gist described above.

[0050] For example, in the embodiment described above, an example was described in which the holding member 3 includes a middle cylinder 4 and an inner cylinder 5. However, the holding member may be composed of multiple parts or a single part, and the configuration of the holding member can be changed as appropriate. In the embodiment described above, an example was described in which the holding member 3 for holding the coating body 10 is provided on the container body 2, and the container body 2 has an outer cylinder 2A and a holding member 3. However, the holding member does not have to be provided on the container body 2, and may be provided independently.

[0051] In the embodiment described above, a coating member 1 equipped with a cap 6 attached to the container body 2 was described. However, the coating member may not have a cap 6. For example, a coating material storage section for containing the coating material M may be provided separately from the coating body 10 and the holding member 3. In this way, the configuration of the coating member can also be changed as appropriate.

[0052] In the embodiments described above, the coating material M was a cosmetic, and the coating member 1 was a cosmetic container. However, the coating material may be something other than a cosmetic. For example, the coating material may be a drawing material. The coating body and coating member according to this disclosure are not limited to cosmetics, but can be applied to various drawing materials such as writing instruments or stationery.
