Description

  The present invention relates to a cosmetic puff.

  As a cosmetic puff, it is important that the user can apply cosmetics such as a foundation effectively and comfortably.

  For example, Patent Document 1 proposes a new configuration for a sponge as a core material of a puff.

Japanese Patent No. 4780597

  FIG. 8 shows a puff 200 as an example of a conventional puff. The puff 200 includes a substantially circular puff body and a band (ribbon) for holding the puff body. When applying the foundation with the puff 200, for example, first put the index finger and middle finger of the dominant hand or the index finger, middle finger and ring finger in the puff belt, and hold the puff with both thumbs and pinky fingers. Subsequently, the foundation is attached to the puff 200. Start applying the foundation from one cheek and then extend the foundation from the inside to the outside of the cheek. The foundation is applied so that the puff 200 is slid from below the eyes to above the ears, then from the nose to the middle of the ears, and from the chin to below the ears. Then, the foundation remaining in the puff 200 is stretched and attached to the forehead. Subsequently, the belt side of the puff 200 is folded in half, and the crease of the puff 200 is used to finish fine parts such as the nose and the eyes. Finish the puff 200 by spreading it out, without applying a foundation, and stroking the entire face with a puff. Thus, the puff 200 needs to be bent because the shape of the face is not uniform over the entire surface but is uneven. Sites such as around the eyes and mouth and in the vicinity of the small nose (regions G1 to G6 in FIG. 7) are difficult regions where it is difficult to make makeup cleanly compared to sites of relatively large areas such as cheeks and foreheads. In the case of the puff 200, when applying makeup to such a difficult area, for example, as shown in FIG. 9, the index finger is inserted between the puff upper surface 200a and the belt, and the thumb and middle finger are in contact with the puff lower surface 200b. Thus, the bottom surface of the puff body is made as small as possible by lifting both ends in the direction of the arrow Z1 and bending the puff body. However, since the puff body has a considerable thickness and is not suitably configured to bend, it is not easy to bend as intended by the user, and even if it is folded, the shape of the tip portion C1 is Since it does not change, there is a limit to reducing the area in contact with the face. In addition, when the puff body is folded, it is necessary to bring the finger into contact with the puff lower surface 200b, which is the surface to which the cosmetic is applied, so that there is a problem that the cosmetic is attached to the finger.

  Based on the above, the present invention provides a cosmetic puff that can make makeup beautifully even in difficult areas where makeup is difficult to make.

  A first invention is a cosmetic puff, which is formed in an oval shape in a plan view, and the oval shape has a blunt end portion and a pointed end portion, and is viewed from a direction orthogonal to the plan view. The end of the cosmetic puff has a curved surface and is a cosmetic puff.

  The inventor of the present invention has found that it is preferable to use a rod-shaped member having a spherical tip in order to make makeup beautifully in a difficult region. Furthermore, pay attention to the fact that the entire face is not a difficult region where makeup is difficult, there is an easy region where makeup is easy over a relatively large area, and there is also an intermediate region between them. The structure of cosmetic puffs was studied. According to the configuration of the first invention, the plan view has an oval shape, and the end portion of the cosmetic puff viewed from the direction orthogonal to the plan view is a curved surface. And is configured in a substantially spherical shape (more precisely, a shape of a part of the sphere). In other words, the pointed end portion of the cosmetic puff having the configuration of the first invention is technically equivalent (equivalent) to a bar-shaped member having a pointed spherical surface. Furthermore, the tip is not protruding from the other part of the cosmetic puff, but is an egg-shaped tip. In other words, a curved outer periphery having a radius of curvature larger than that of the tip portion has a structure that smoothly continues to the tip portion. For this reason, according to the cosmetic puff of the first invention, makeup can be made by smoothly moving the difficult region, the intermediate region, and the easy region. That is, the user can not only make the makeup easily, but also make the makeup in the difficult region neatly due to the substantially spherical shape of the tip.

  According to a second aspect, in the configuration of the first aspect, the ratio α1 (D1 / L1) of the length (D1) of the short axis of the egg shape to the length (L1) of the long axis is 0.70 or more and 0. .85 or less, and the position of the short axis approaches the blunt end side from an intermediate position corresponding to half the length of the long axis (L2), and the long axis of the offset length (L3) The ratio α2 (L3 / L1) to the length (L1) is 0.07 or more and 0.09 or less, and the ratio α3 (the thickness (h1) of the cosmetic puff to the length (L1) of the major axis is h1 / L1) is 0.08 or more and 0.16 or less, and the ratio α4 (h1 / D1) of the thickness (h1) of the cosmetic puff to the length (D1) of the minor axis is 0.10 or more and 0 A cosmetic puff that is 20 or less.

  According to the configuration of the second invention, the short axis is closer to the blunt end side, and in the oval shape, the apex side is formed with an acute angle and the blunt end side is formed with an obtuse angle. Moreover, the thickness of the cosmetic puff is formed thin in relation to the major axis and the minor axis. Thereby, since the spherical shape of a point part can be made small, the makeup | decoration of a difficult area | region can be performed more beautifully.

The third invention is the structure of either the first invention or the second invention,
A region near the tip of the egg shape is a first region, a region from the short axis to the blunt end of the egg shape is a third region, between the first region and the third region. When the area is the second area,
The ratio β1 (R1 / R2) of the curvature radius R1 of the outer periphery of the first region to the curvature radius R2 of the outer periphery of the second region is 0.15 or more and 0.25 or less,
The cosmetic puff has a ratio β2 (R1 / R3) of a curvature radius R1 of the outer periphery of the first region to a curvature radius R3 of the outer periphery of the third region of 0.35 or more and 0.45 or less.

  The inventor of the present invention can make makeup in a difficult area neatly, can efficiently perform makeup in an intermediate area and an easy area, and can easily hold and operate each part. The relationship between the radii of curvature was studied, and as a result of execution and error, it was found that according to the configuration of the third invention, these technical problems can be addressed.

According to a fourth aspect of the invention, in any one of the first to third aspects of the invention,
The shape of the makeup puff in the direction orthogonal to the plan view is a substantially rectangular shape with both ends rounded, and the end of the surface that the user touches during makeup is a curved surface, and the curvature radius of the curved surface The ratio γ1 (R4 / R1) of (R4) to the radius of curvature R1 of the first region is a cosmetic puff that is 0.90 or more and 1.10 or less.

  According to the configuration of the fourth aspect of the invention, the radius of curvature in the vicinity of the tip of the egg-shaped shape is almost the same when viewed from any direction, so the tip side becomes a beautiful spherical shape. With this shape, it is possible to cleanly make up difficult areas.

  According to the cosmetic puff according to the present invention, it is possible to cleanly apply even in difficult regions where it is difficult to cleanly apply makeup.

Note that description of configurations that can be appropriately implemented by those skilled in the art will be omitted, and only the basic configuration of the present invention will be described.

  As shown in FIG. 1, the cosmetic puff 1 includes a main body 10 that is a main body of the puff, a thin cover 30 that covers a substantially upper half of the main body 10, and a band (ribbon) 50 that is a holding portion. The main body 10 is a sponge having a large number of fine pores. The material of the main body 10 is, for example, latex foam, wet urethane foam, silicone rubber, or nitrile butadiene rubber. As shown in FIGS. 2 to 4, the cosmetic puff 1 has an oval shape in plan view. As shown in FIGS. 5 and 6, the shape of the cosmetic puff 1 viewed from the direction orthogonal to the plan view is a substantially rectangular shape with both ends having a predetermined roundness. As described above, the outer periphery of the region A1 (see FIG. 4) in the vicinity of the tip of the cosmetic puff 1 is curved in both a plan view and a direction orthogonal to the plan view. Part of the shape). This means that the region A1 is equivalent to a bar-shaped member having a spherical tip. And area | region A1 does not protrude from the other part of the cosmetic puff 1, but is an egg-shaped point. That is, the curved outer periphery of the region A2 having an outer periphery with a radius of curvature larger than that of the region A1 has a structure that smoothly continues to the outer periphery of the region A1. For this reason, according to the makeup puff 1, makeup can be made by smoothly moving the difficult region, the intermediate region, and the easy region. That is, the user can not only make easy makeup and an intermediate region where makeup is easy, but also can make makeup in difficult regions with the substantially spherical shape of the region A1.

  As elements defining the shape of the cosmetic puff 1 when viewed in plan, there are the major axis length L1, the minor axis length D1, and the minor axis position of the egg shape shown in FIG. As shown in FIG. 4, when the length of the major axis of the egg-shaped shape of the cosmetic puff 1 is L1, the portion corresponding to the half length L2 (the portion indicated by the auxiliary line X1) is the minor axis. It does not correspond to (the position having the maximum width), but the portion slightly closer to the blunt end side (corresponding to the length L3) is the short axis (the portion indicated by the auxiliary line X2), and the length D1. The auxiliary line Y <b> 1 indicates an egg-shaped center line of the cosmetic puff 1. The ratio α1 (D1 / L1) of the minor axis length D1 to the major axis length L1 is not less than 0.70 and not more than 0.85, and preferably not less than 0.73 and not more than 0.80. The ratio α2 (L3 / L1) of the length L3 of the short axis close to the blunt end to the length L1 of the long axis is 0.07 or more and 0.09 or less. In this embodiment, L1 is 63 mm (millimeters), D1 is 48 mm, and α1 is 0.76. L3 is 5 mm and α2 is 0.08.

  The ratio α3 (h1 / L1) of the thickness h1 (see FIG. 5) of the cosmetic puff to the length L1 of the major axis is 0.08 or more and 0.16 or less, and the minor axis of the thickness p1 of the cosmetic puff is The ratio α4 (h1 / D1) to the length D1 is not less than 0.10 and not more than 0.20. In the present embodiment, h1 is 7 mm. α3 is 0.11 and α4 is 0.15.

  For convenience of description of the egg shape of the cosmetic puff 1, the egg shape is divided into several regions. The region in the vicinity of the tip is the region A1 (see FIG. 4) as the first region, the region from the minor axis to the blunt end is the region A3 as the third region, and the region between the region A1 and the region A3 is the second. The region is an area A2. The ratio β1 (R1 / R2) of the curvature radius R1 of the outer periphery of the region A1 to the curvature radius R2 of the outer periphery of the region A2 is 0.15 or more and 0.25 or less, and the outer periphery of the region A1 with respect to the curvature radius R3 of the outer periphery of the region A3. The ratio β2 (R1 / R3) of the curvature radius R1 is 0.35 or more and 0.45 or less. In the present embodiment, R1 is 10 mm, R2 is 45 mm, and R3 is 25 mm. Β1 is 0.22 and β2 is 0.40.

  As shown in FIG. 5, there is a space K <b> 1 between the band 50 and the cover 30, and the user can hold the cosmetic puff 1 by inserting a finger into the space K <b> 1. As shown in FIGS. 5 and 6, the shape in the direction orthogonal to the plan view is substantially rectangular, and the end of the surface that contacts the user's face during makeup is a curved surface (see B1 in FIG. 6). . The ratio γ1 (R4 / R1) of the curvature radius (R4) of the curved surface (B1 in FIG. 6) to the curvature radius R1 of the region A1 is 0.90 or more and 1.10 or less. In the present embodiment, R4 is 10 mm and R1 is also 10 mm, so γ1 is 1. That is, the part in contact with the user's face is spherical (more precisely, it is the shape of a part of the sphere). Using this spherical shape, makeup can be carried out neatly in the difficult areas G1 to G6 shown in FIG.

  That is, it is possible to cleanly apply a small area such as the regions G1 to G6 in FIG. 7 without performing deformation such as bending the makeup puff 1.

  The cosmetic container of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.
