 The present invention relates to a cosmetic puff used for applying cosmetics, etc.
 As shown in
 With conventional cosmetic puffs such as those shown in
 Moreover, with such cosmetic puffs, the cosmetic applicator surface is a top surface
 With the cosmetic puff
 Accordingly, an object of the present invention is to provide a cosmetic puff which is easy to hold when applying cosmetics, which can easily apply cosmetics both to large, flat areas such as the forehead, and small, uneven areas such as around the nostrils and eyes, and which does not soil user's fingers even when the same puff is used repeatedly.
 The inventor discovered that by forming slant sides on a cosmetic puff in such a way that the slant sides can be used for applying cosmetics, it becomes possible to differentiate the cosmetic applicator surface from the surface to be held with the fingers when applying cosmetics, thus preventing use's fingers from being soiled when a cosmetic puff is used repeatedly, while rendering it unnecessary to bend the cosmetic puff so as to be wrapped around a finger when applying cosmetics, thus making the cosmetic puff more comfortable to hold.
 Namely, the present invention provides a cosmetic puff including a bottom surface and a slant surface without unevenness which constitutes the cosmetic application surface, wherein the thickness of the cosmetic puff increases gradually along the slant surface from the peripheral portion of the bottom surface towards the center portion of the puff.
 The present invention is explained in detail below with reference to the drawings. In each drawing, the same symbol indicates an identical or equivalent component.
 This cosmetic puff
 In the present invention, the absence of unevenness in the slant surface
 If a convex or concave portion is formed on part of a surface forming the cosmetic puff, cosmetics will accumulate unnecessarily in the concave portion or on the edge of the convex part; this can be prevented by forming the surfaces flat.
 This cosmetic puff
 Considering the ease of handling cosmetic puff
 Angle θ of slant surface
 From the standpoint of ease of handling, the size of bottom surface
 The cosmetic puff of the present invention can take a variety of forms, as long as it includes a slant surface without unevenness that is used to apply cosmetics. For example, cosmetic puff
 Furthermore, slant surface
 As shown in
 The cosmetic puff of the present invention need not have a cross-section with bilateral symmetry, so multiple slant surfaces
 In addition, the cosmetic puff of the present invention is not limited to a truncated cone or truncated pyramid shape or to a cone or semicircle, but can also be made with slant surfaces
 It is also possible for bottom surface
 A sponge or foam, etc. made of polyurethane rubber, silicone rubber, nitryl butadiene rubber or other resin may be used as the material forming the cosmetic puff of the present invention. Such sponges and foams, etc. may be the same foam materials as those used in known cosmetic puffs. By contrast, formation by wrapping cotton or other fibers is most often not desirable because cosmetics such as the powder, cream and foundation may not be taken up as well by the cosmetic puff, and may be more difficult to apply.
 The method of manufacturing the cosmetic puff of the present invention may be the same as for a conventional cosmetic puff. In this case, the cosmetic puff of the present invention is easy to manufacture because it does not require special convex or concave parts on the top, bottom or slant surface.
 There are no particular limitations on how the cosmetic puff of the present invention is contained, but as shown in
 With the cosmetic puff of the present invention, the ease of use of the cosmetic puff is improved, cosmetics can be easily applied both to large, flat areas such as the forehead and small, uneven areas such as around the nostrils and eyes, and soiling of the user's fingers holding the cosmetic puff can be prevented.
