Definitions
- the present invention relates to a technique for providing a cosmetic puff.
- Japanese non-examined laid-open Patent Publication No. 2007-195614 discloses a cosmetic puff for use in applying skin lotion by patting.
- the known cosmetic puff includes an air-laid non-woven fabric sheet.
- it is required to provide a cosmetic puff having enhanced usability to release an appropriate amount of lotion according to the force with which a user pats the skin with the cosmetic puff impregnated with skin lotion.
- the representative cosmetic puff according to this invention includes an air-laid non-woven fabric sheet manufactured by an air-laid technique.
- the representative cosmetic puff is preferably applied to the structure of a cosmetic puff which is used, as it is or with cosmetic liquid, powder, gel or cream contained in or on it, to pat the user's face when wearing makeup.
- the representative cosmetic puff particularly includes pulp fibers and hydrophobic synthetic fibers.
- the “hydrophobic synthetic fibers” here may include various kinds of hydrophobic synthetic fibers, and typically, one or more of polyethylene terephthalate (PET) fibers, polypropylene (PP) fibers, nylon fibers or the like can be used as hydrophobic synthetic fibers.
- PET polyethylene terephthalate
- PP polypropylene
- nylon fibers or the like can be used as hydrophobic synthetic fibers.
- the air-laid non-woven fabric sheet contains the hydrophobic synthetic fibers at the rate of 10 to 50% by weight.
- the “rate of recovery after loaded” is defined as the rate of recovery of the thickness of the specimen based on the difference of the thickness measured before and after application of a predetermined load to the wetted specimens.
- the “rate of one-time moisture release” here is defined as the rate of moisture release based on the amount of moisture which is released at one time from the specimen to filter paper when a predetermined load is generally applied to the wetted specimen with the filter paper stacked on top of the specimen.
- the “rate of fraction moisture release” here is defined as the rate of moisture release based on the amount of moisture which is finally released from the specimen to filter paper when a predetermined load is generally applied several times to the wetted specimen with the filter paper stacked on top of the specimen.
- the pulp fibers of the air-laid non-woven fabric sheet have a fiber weight per unit length of 0.20 mg/m or more.
- a pulp fiber having a relatively heavy fiber weight per unit length has an average pore size (void diameter) of 100 ⁇ m or more and has a strong skeleton structure, so that the cosmetic puff having a higher rate of recovery after loaded in the wet state, a higher rate of one-time moisture release and a higher rate of fraction moisture release can be realized.
- a cosmetic puff according to another embodiment of this invention includes an air-laid non-woven fabric sheet, and the air-laid non-woven fabric sheet contains pulp fibers with a fiber weight per unit length of 0.20 mg/m or more.
- pulp fibers having a relatively heavy fiber weight per unit length has an average pore size (void diameter) of 100 ⁇ m or more and has a strong skeleton structure, so that the cosmetic puff having a higher rate of recovery after loaded in the wet state, a higher rate of one-time moisture release and a higher rate of fraction moisture release can be realized.
- the air-laid non-woven fabric sheet includes surface layers, and at least one of the surface layers is formed of rayon fibers.
- either one of the surface layers of the air-laid non-woven fabric sheet may be formed of rayon fibers, or both of the surface layers of the air-laid non-woven fabric sheet may be formed of rayon fibers.
- At least one of the surface layers of the air-laid non-woven fabric sheet includes moisturizer application regions to which a moisturizer is applied and moisturizer non-application regions which are regions other than the moisturizer application regions. Further, this surface layer has an area in which the moisturizer application regions and the moisturizer non-application regions are alternately arranged at least in one of the directions of the width and the length of the air-laid non-woven fabric sheet.
- either one of the surface layers of the air-laid non-woven fabric sheet may include an area in which the moisturizer application regions and the moisturizer non-application regions are alternately arranged, or bath of the surface layers of the air-laid non-woven fabric sheet may include an area in which the moisturizer application regions and the moisturizer non-application regions are alternately arranged.
- the “moisturizer” here may preferably include diglycerin, triglycerin, ethylene glycol, propylene glycol, 1,3-butylene glycol, liquid paraffin, squalane, vaseline, olive oil, soy oil, safflower oil, camellia oil, jojoba oil, almond oil, castor oil, palm oil, mink oil, vitamin dimethyl silicone, silicone oil, modified silicone, sorbitol, sucrose, glucose, maltose, bees wax, hyaluronan, placental extract, aloe extract, chamomilla recutita , peach leaf extract, collagen, loofah extract, hinokitiol.
- the cosmetic puff in the moisturizer application regions, can be provided with a moist texture and thus can provide an improved texture.
- the moisturizer non-application regions are kept with an apparent sheet thickness (kept bulky) without application of the moisturizer, so that it is effective in improving the appearance of the cosmetic puff (adding a quality appearance to it). Therefore, the cosmetic puff can be provided with both of an improved texture and an improved appearance.

- FIG. 2 shows results of evaluation of each specimen in the working examples 1 to 7 and the comparative examples 1 and 2 in this embodiment on criteria A, B, C. Further, in this embodiment, the fiber length and the fiber weight of the pulp fibers are the “average fiber length” and the fiber weight (also referred to as the “fiber roughness”) per unit length, respectively. From the evaluation results shown in FIG. 2 , evaluations are made as follows:
- the rate of recovery after loaded of every specimen in the working examples 1 to 7 exceeds 7%, and it is thus verified that the specimens in the working examples 1 to 7 have higher performance of recovery after loaded, compared with the specimens of the comparative examples 1 and 2 in which the rate of recovery after loaded is below 7%. Therefore, when, for example, a cosmetic puff impregnated with skin lotion is used for patting, a sufficient amount of release of skin lotion can be provided. Further, due to the higher performance of releasing skin lotion, such a cosmetic puff is economical without wasting skin lotion
- the rate of one-time moisture release of every specimen in the working examples 1 to 7 exceeds 75%, and it is thus verified that the specimens in the working examples 1 to 7 have higher performance of one-time moisture release (at one time or in one step), compared with the specimens of the comparative examples 1 and 2 in which the rate of one-time moisture release is below 75%. Therefore, when, for example, a cosmetic puff impregnated with skin lotion is used for patting, a sufficient amount of release of skin lotion can be provided even by lightly patting the skin. In other words, it is not necessary to pat the skin with a strong force which may put a strain on the skin.
- the rate of (first to second) moisture release of every specimen exceeds 85%, and the rate of (first to third) moisture release of every specimen exceeds 90%. It is thus verified that the specimens in the working examples 1 to 7 have higher performance of fraction moisture release (in several steps), compared with the specimens of the comparative examples 1 and 2 in which the rate of (first to second) moisture release is below 85% and the rate of (first to third) moisture release is below 90%. Therefore, when, for example, a cosmetic puff impregnated with skin lotion is used for patting several times (in several steps), a sufficient amount of release of skin lotion can be continuously provided. Application of skin lotion to the skin by patting in several steps is effective for increasing moisture in the skin.
- a cosmetic puff having enhanced usability can be provided by designing it to release an appropriate amount of skin lotion according to the force with which a user pats the skin with the cosmetic puff impregnated with skin lotion.
- each of the air-laid non-woven fabric sheets corresponding to the specimens of the working examples 1 to 7 contains pulp fibers with a fiber weight per unit length of 0.20 mg/m or more.
- a pulp fiber has an average pore size (void diameter) of 100 ⁇ m or more and has a strong skeleton structure, so that the rate of recovery after loaded in the wet state, the rate of one-time moisture release and the rate of fraction moisture release can be increased.
- void diameter average pore size
- such a sheet is effective for gradually discharging the skin lotion retained in space between the fibers, to the surface layer.
- each of the air-laid non-woven fabric sheets corresponding to the specimens of the working examples 2 to 6 contains 10 to 50% of polyethylene terephthalate fibers by weight.
- the rate of recovery after loaded in the wet state, the rate of one-time moisture release and the rate of fraction moisture release can be further increased, so that the effect of gradually discharging the skin lotion retained in space between the fibers, to the surface layer can be further enhanced.
- each of the air-laid non-woven fabric sheets corresponding to the specimens of the working examples 1 to 7 contains rayon fibers in areas corresponding to the surface layers 120 , so that the cosmetic puff provide a smooth texture in use. Either one of the two surface layers 120 may be formed by the rayon fibers, as necessary.
- the mixture ratio of a binder contained in the air-laid non-woven fabric sheet is preferably set to 5 to 15% by weight. If the mixture ratio of the binder is decreased to below 5% by weight, disadvantageously, the rate of recovery after loaded in the wet state is decreased, and the amount of first moisture release is increased. Further, if the mixture ratio of the binder exceeds 15% by weight, disadvantageously, the material is hardened and rendered unsuitable for a cosmetic puff.
- the content of polyethylene terephthalate fibers in the air-laid non-woven fabric sheet is preferably set to 10 to 50% by weight.
- the polyethylene terephthalate fibers are hydrophobic, and if the content of polyethylene terephthalate fibers exceeds 50% by weight, disadvantageously, most of the skin lotion absorbed therein is immediately released by first patting, and an increase in the amount of polyethylene terephthalate fibers leads to cost increase.
- other hydrophobic synthetic fibers may be used. In this case, polypropylene (PP) fibers, nylon fibers or the like can be used as the other hydrophobic synthetic fibers.

Description
- 1. Field of the Invention
- The present invention relates to a technique for providing a cosmetic puff.
- 2. Description of the Related Art
- Japanese non-examined laid-open Patent Publication No. 2007-195614 discloses a cosmetic puff for use in applying skin lotion by patting. The known cosmetic puff includes an air-laid non-woven fabric sheet. In designing such cosmetic puff it is required to provide a cosmetic puff having enhanced usability to release an appropriate amount of lotion according to the force with which a user pats the skin with the cosmetic puff impregnated with skin lotion.
- Accordingly, it is an object of the invention to provide an effective technique for releasing an appropriate amount of skin lotion according to user's patting force with respect to a cosmetic puff having an air-laid non-woven fabric sheet formed of pulp fibers.
- The above-described problem can be solved by the features of the claimed invention.
- The representative cosmetic puff according to this invention includes an air-laid non-woven fabric sheet manufactured by an air-laid technique. The representative cosmetic puff is preferably applied to the structure of a cosmetic puff which is used, as it is or with cosmetic liquid, powder, gel or cream contained in or on it, to pat the user's face when wearing makeup. The representative cosmetic puff particularly includes pulp fibers and hydrophobic synthetic fibers. The “hydrophobic synthetic fibers” here may include various kinds of hydrophobic synthetic fibers, and typically, one or more of polyethylene terephthalate (PET) fibers, polypropylene (PP) fibers, nylon fibers or the like can be used as hydrophobic synthetic fibers. With such a structure, by provision of the hydrophobic synthetic fibers, the cosmetic puff can provide a desired moisture releasing property, so that an appropriate amount of skin lotion can be released according to user's patting force.
- Further, in a further embodiment of the cosmetic puff according to this invention, preferably, the air-laid non-woven fabric sheet contains the hydrophobic synthetic fibers at the rate of 10 to 50% by weight. With such a structure, by defining the content of the hydrophobic synthetic fibers, particularly, the rate of recovery after loaded in the wet state, the rate of one-time moisture release and the rate of fraction moisture release can be increased. The “rate of recovery after loaded” here is defined as the rate of recovery of the thickness of the specimen based on the difference of the thickness measured before and after application of a predetermined load to the wetted specimens. The “rate of one-time moisture release” here is defined as the rate of moisture release based on the amount of moisture which is released at one time from the specimen to filter paper when a predetermined load is generally applied to the wetted specimen with the filter paper stacked on top of the specimen. Further, the “rate of fraction moisture release” here is defined as the rate of moisture release based on the amount of moisture which is finally released from the specimen to filter paper when a predetermined load is generally applied several times to the wetted specimen with the filter paper stacked on top of the specimen.
- Further, in a further embodiment of the cosmetic puff according to this invention, preferably, the pulp fibers of the air-laid non-woven fabric sheet have a fiber weight per unit length of 0.20 mg/m or more. Such a pulp fiber having a relatively heavy fiber weight per unit length has an average pore size (void diameter) of 100 μm or more and has a strong skeleton structure, so that the cosmetic puff having a higher rate of recovery after loaded in the wet state, a higher rate of one-time moisture release and a higher rate of fraction moisture release can be realized.
- A cosmetic puff according to another embodiment of this invention includes an air-laid non-woven fabric sheet, and the air-laid non-woven fabric sheet contains pulp fibers with a fiber weight per unit length of 0.20 mg/m or more. Such a pulp fiber having a relatively heavy fiber weight per unit length has an average pore size (void diameter) of 100 μm or more and has a strong skeleton structure, so that the cosmetic puff having a higher rate of recovery after loaded in the wet state, a higher rate of one-time moisture release and a higher rate of fraction moisture release can be realized.
- In a further embodiment of the cosmetic puff according to this invention, preferably, the air-laid non-woven fabric sheet includes surface layers, and at least one of the surface layers is formed of rayon fibers. In this respect, either one of the surface layers of the air-laid non-woven fabric sheet may be formed of rayon fibers, or both of the surface layers of the air-laid non-woven fabric sheet may be formed of rayon fibers. With such a structure, the cosmetic puff can provide a smooth texture in use.

This detailed description is merely intended to teach a person skilled in the art further details for practicing preferred aspects of the present teachings and is not intended to limit the scope of the invention. Only the claims define the scope of the claimed invention.

- A representative
cosmetic puff 100 as a preferred embodiment according to the invention is now described with reference to the drawings.FIG. 1 is a perspective external view showing acosmetic puff 100 according to this embodiment. - As shown in
FIG. 1 , thecosmetic puff 100 according to this embodiment has a sheet-like or plate-like form as a whole and includes aninner layer 110 in the form of a sheet andsurface layers 120 in the form of laminated sheets on the both sides of theinner layer 110. Thecosmetic puff 100 is formed by an air-laid non-woven fabric sheet which is manufactured by a known air-laid technique. Thecosmetic puff 100 is a cosmetic tool which is used, as it is or with cosmetic liquid, powder, cream or gel contained in or on it, to pat the user's face when wearing makeup. The cosmetic puff is also referred to as a “cosmetic cotton”. Each of thesurface layers 120 is typically formed by a non-woven fabric primarily made of at least one kind of fibers of rayon, cotton, silk, pulp or the like. Theinner layer 110 contains at least pulp fibers and polyethylene terephthalate (PET) fibers. Alternatively, theinner layer 110 may be formed by an air-laid non-woven fabric sheet containing pulp fibers and not containing polyethylene terephthalate (PET) fibers, as necessary. Further, thesurface layers 120 may be formed by the same fibers as theinner layer 110. Theinner layer 110 and thesurface layers 120 are features that correspond to the “air-laid non-woven fabric sheet” and the “surface layers”, respectively, according to this invention. Further, the pulp fibers and polyethylene terephthalate fibers in theinner layer 110 are features that correspond to the “pulp fibers” and the “hydrophobic synthetic fibers”, respectively, according to this invention. - In developing cosmetic puffs of this kind, particularly in order to realize release of an appropriate amount of skin lotion according to the force with which a user pats his or her skin with a cosmetic puff impregnated with skin lotion, it is required to provide the cosmetic puff having a desired moisture releasing property so that the lotion once retained in the cosmetic puff can be released by an appropriate amount under predetermined conditions. Therefore, applicants of this invention have studied on the structure and performance of cosmetic puffs of this kind. As the results of the study, they successfully found that a cosmetic puff having a desired moisture releasing property can be realized by forming the above-described
inner layer 110 in the form of a non-wove fabric sheet which is formed by an air-laid non-wove fabric sheet containing pulp fibers and hydrophobic synthetic fibers. - Now, performance evaluations conducted for quantitative verification of the effects of the cosmetic puff according to the invention are explained in detail. For the performance evaluations, particularly, criterion A (rate of recovery after loaded), criterion B (rate of one-time moisture release), and criterion C (rate of fraction moisture release) were measured on each of specimens in working examples 1 to 7 and comparative examples 1 and 2 which are described below. The “rate of recovery after loaded” here is defined as the rate of recovery of the thickness of the specimen based on the difference of the thickness measured before and after application of a predetermined load to the wetted specimens. The “rate of one-time moisture release” here is defined as the rate of moisture release based on the amount of moisture which is released at one time from the specimen to filter paper when a predetermined load is generally applied to the wetted specimen with the filter paper stacked on top of the specimen. Further, the “rate of fraction moisture release” here is defined as the rate of moisture release based on the amount of moisture which is finally released from the specimen to filter paper when a predetermined load is generally applied several times to the wetted specimen with the filter paper stacked on top of the specimen.

- (Rate of Recovery after Loaded)
- For measurements of the rate of recovery after loaded, a portable thickness gage (CR-10A of Daiei Kagaku Seiki Mfg. Co., Ltd.) is used to measure the thickness of each of the wetted specimens while applying a first pressure (1.96 kPa (20 gf/cm2)) or a second pressure (3.92 kPa (40 gf/cm2)) by a pressure-foot (1 cm2 (φ11.28 mm)). The rate of recovery after loaded is obtained by the equation of (Dc−Db)/Db×100.
- For measurements of the rate of one-time moisture release, first, filter paper having dimensions of 50×50 mm is laid on top of each specimen having dimensions of 50×50 mm and wetted (impregnated with 2 ml of test liquid). Thereafter, a predetermined pressure (17.5 kgf/cm2) is applied thereto and the amount of moisture released from each specimen to the filter case is calculated. Specifically, a weight Wa of each wetted specimen and a weight Wb of ten pieces of filter paper are measured in advance, and then the ten pieces of filter paper (of the weight Wb) are laid on top of each wetted specimen. Subsequently, the above-described predetermined pressure is applied to the filter paper from above for 15 seconds and thereafter a weight Wc of the ten pieces of filter paper is measured. Then, the rate of one-time moisture release (%) is obtained by the equation of (Wc−Wb)/Wa×100.
- For measurements of the rate of fraction moisture release, first, filter paper having dimensions of 50×50 mm is laid on top of each specimen having dimensions of 50×50 min and wetted (impregnated with 2 ml of test liquid). Thereafter, a predetermined pressure (34.6 kgf/cm2) is applied thereto in three steps and the amount of moisture released from each specimen to the filter case is calculated after each application of pressure. Specifically, in the first step, a weight Wd of each wetted specimen and a weight We often pieces of filter paper are measured in advance, and then the ten pieces of filter paper (of the weight We) are laid on top of each wetted specimen. Subsequently, the above-described predetermined pressure is applied to the filter paper from above for 5 seconds and thereafter a weight Wf of the ten pieces of filter paper is measured. Then, the rate of the first moisture release (%) is obtained by the equation of (Wf−We)/Wd×100.
- Subsequently, in the second step, a weight Wg of ten new pieces of filter paper is measured, and then the ten pieces of filter paper (of the weight Wg) are laid on top of each wetted specimen obtained in the first step. Subsequently, the above-described predetermined pressure is applied to the filter paper from above for 5 seconds and thereafter a weight Wh of the ten pieces of filter paper is measured. Subsequently, in the third step, a weight Wi of another ten new pieces of filter paper is measured, and then the ten pieces of filter paper (of the weight Wi) are laid on top of each wetted specimen obtained in the second step. Subsequently, the above-described predetermined pressure is applied to the filter paper from above for 5 seconds and thereafter a weight Wj of the ten pieces of filter paper is measured. Then, the rate of the second moisture release (%) is obtained by the equation of (Wh−Wg)/Wd×100.
- Subsequently, in the third step, a weight Wg of ten new pieces of filter paper is measured, and then the ten pieces of filter paper (of the weight Wg) are laid on top of each wetted specimen obtained in the first step. Subsequently, the above-described predetermined pressure is applied to the filter paper from above for 5 seconds and thereafter a weight Wh of the ten pieces of filter paper is measured. Subsequently, in the third step, a weight Wi of another ten new pieces of filter paper is measured, and then the ten pieces of filter paper (of the weight Wi) are laid on top of each wetted specimen obtained in the second step. Subsequently, the above-described predetermined pressure is applied to the filter paper from above for 5 seconds and thereafter a weight Wj of the ten pieces of filter paper is measured. Then, the rate of the third moisture release (%) is obtained by the equation of (Wj−Wi)/Wd×100.
-
FIG. 2 shows results of evaluation of each specimen in the working examples 1 to 7 and the comparative examples 1 and 2 in this embodiment on criteria A, B, C. Further, in this embodiment, the fiber length and the fiber weight of the pulp fibers are the “average fiber length” and the fiber weight (also referred to as the “fiber roughness”) per unit length, respectively. From the evaluation results shown inFIG. 2 , evaluations are made as follows: - As for the criterion A, the rate of recovery after loaded of every specimen in the working examples 1 to 7 exceeds 7%, and it is thus verified that the specimens in the working examples 1 to 7 have higher performance of recovery after loaded, compared with the specimens of the comparative examples 1 and 2 in which the rate of recovery after loaded is below 7%. Therefore, when, for example, a cosmetic puff impregnated with skin lotion is used for patting, a sufficient amount of release of skin lotion can be provided. Further, due to the higher performance of releasing skin lotion, such a cosmetic puff is economical without wasting skin lotion
- As for the criterion B, the rate of one-time moisture release of every specimen in the working examples 1 to 7 exceeds 75%, and it is thus verified that the specimens in the working examples 1 to 7 have higher performance of one-time moisture release (at one time or in one step), compared with the specimens of the comparative examples 1 and 2 in which the rate of one-time moisture release is below 75%. Therefore, when, for example, a cosmetic puff impregnated with skin lotion is used for patting, a sufficient amount of release of skin lotion can be provided even by lightly patting the skin. In other words, it is not necessary to pat the skin with a strong force which may put a strain on the skin.
- As for the criterion C, in the working examples 1 to 7, the rate of (first to second) moisture release of every specimen exceeds 85%, and the rate of (first to third) moisture release of every specimen exceeds 90%. It is thus verified that the specimens in the working examples 1 to 7 have higher performance of fraction moisture release (in several steps), compared with the specimens of the comparative examples 1 and 2 in which the rate of (first to second) moisture release is below 85% and the rate of (first to third) moisture release is below 90%. Therefore, when, for example, a cosmetic puff impregnated with skin lotion is used for patting several times (in several steps), a sufficient amount of release of skin lotion can be continuously provided. Application of skin lotion to the skin by patting in several steps is effective for increasing moisture in the skin.
- As described above, by using an air-laid non-woven fabric sheet corresponding to any one of the specimens of the working examples 1 to 7, a cosmetic puff having enhanced usability can be provided by designing it to release an appropriate amount of skin lotion according to the force with which a user pats the skin with the cosmetic puff impregnated with skin lotion.
- Specifically, each of the air-laid non-woven fabric sheets corresponding to the specimens of the working examples 1 to 7 contains pulp fibers with a fiber weight per unit length of 0.20 mg/m or more. Such a pulp fiber has an average pore size (void diameter) of 100 μm or more and has a strong skeleton structure, so that the rate of recovery after loaded in the wet state, the rate of one-time moisture release and the rate of fraction moisture release can be increased. Thus, such a sheet is effective for gradually discharging the skin lotion retained in space between the fibers, to the surface layer. Further, each of the air-laid non-woven fabric sheets corresponding to the specimens of the working examples 2 to 6 contains 10 to 50% of polyethylene terephthalate fibers by weight. Therefore, in this case, the rate of recovery after loaded in the wet state, the rate of one-time moisture release and the rate of fraction moisture release can be further increased, so that the effect of gradually discharging the skin lotion retained in space between the fibers, to the surface layer can be further enhanced.
- Further, each of the air-laid non-woven fabric sheets corresponding to the specimens of the working examples 1 to 7 contains rayon fibers in areas corresponding to the surface layers 120, so that the cosmetic puff provide a smooth texture in use. Either one of the two
surface layers 120 may be formed by the rayon fibers, as necessary. - Further, the mixture ratio of a binder contained in the air-laid non-woven fabric sheet is preferably set to 5 to 15% by weight. If the mixture ratio of the binder is decreased to below 5% by weight, disadvantageously, the rate of recovery after loaded in the wet state is decreased, and the amount of first moisture release is increased. Further, if the mixture ratio of the binder exceeds 15% by weight, disadvantageously, the material is hardened and rendered unsuitable for a cosmetic puff.
- Further, the content of polyethylene terephthalate fibers in the air-laid non-woven fabric sheet is preferably set to 10 to 50% by weight. The polyethylene terephthalate fibers are hydrophobic, and if the content of polyethylene terephthalate fibers exceeds 50% by weight, disadvantageously, most of the skin lotion absorbed therein is immediately released by first patting, and an increase in the amount of polyethylene terephthalate fibers leads to cost increase. Further, alternatively or in addition to the polyethylene terephthalate fibers, other hydrophobic synthetic fibers may be used. In this case, polypropylene (PP) fibers, nylon fibers or the like can be used as the other hydrophobic synthetic fibers.
- In the
cosmetic puff 100 having the above-described structure, preferably, a moisturizer is applied to the surface layers 120 in order to provide a moist texture. Now, acosmetic puff 200 with a moisturizer applied thereto is explained with reference toFIGS. 3 and 4 .FIG. 3 is a plan view of thecosmetic puff 200 according to this embodiment, andFIG. 4 is a sectional view of thecosmetic puff 200 which is taken along line A-A inFIG. 3 . - As shown in
FIG. 3 , thecosmetic puff 200 as a representative embodiment according to the invention has surface layers 220 each includingmoisturizer application regions 221 to which a moisturizer is applied andmoisturizer non-application regions 222 or regions other than themoisturizer application regions 221. Thecosmetic puff 200 has an area in which themoisturizer application regions 221 and themoisturizer non-application regions 222 are alternately arranged in the direction of the width of the cosmetic puff 200 (which direction is set to coincide with the horizontal direction inFIG. 3 ). Specifically, each of themoisturizer application regions 221 is defined as an elongated region having an application width d1 in the horizontal direction and an application width d2 in the vertical direction. Themoisturizer application regions 221 are arranged with pitches d3 in the horizontal direction. Further, each of themoisturizer non-application regions 222 is defined as a region between adjacentmoisturizer application regions 221. As shown inFIG. 4 , due to application of the moisturizer, a sheet thickness h1 of themoisturizer application region 221 is rendered smaller than a sheet thickness h2 of themoisturizer non-application region 222. By such arrangement of themoisturizer application regions 221 shown inFIG. 3 , a so-called “stripe pattern” is formed. Themoisturizer application regions 221 and themoisturizer non-application regions 222 here are features that correspond to the “moisturizer application regions” and the “moisturizer non-application regions”, respectively, according to this invention. - As the moisturizer to be applied to the
moisturizer application regions 221, typically, glycerin can be used. This moisturizer has a softening property as well as the moisturizing property, so that it is also referred to as a softener. As the moisturizer other than glycerin, at least one of the following materials can be used: diglycerin, triglycerin, ethylene glycol, propylene glycol, 1,3-butylene glycol, liquid paraffin, squalane, vaseline, olive oil, soy oil, safflower oil, camellia oil, jojoba oil, almond oil, castor oil, palm oil, mink oil, vitamin E, dimethyl silicone oil, modified silicone, sorbitol, sucrose, glucose, maltose, bees wax, hyaluronan, placental extract, aloe extract, chamomilla recutita, peach leaf extract, collagen, loofah extract, hinokitiol. Further, polyhydric alcohol or surface active agent may also be added as an auxiliary to the moisturizer. - With such a structure, in the
moisturizer application regions 221, the cosmetic puff can be provided with a moist texture and thus can provide an improved texture. Themoisturizer non-application regions 222 are kept with an apparent sheet thickness (kept bulky) without application of the moisturizer as shown inFIG. 4 , so that it is effective in improving the appearance of the cosmetic puff (adding a quality appearance to it). Therefore, the cosmetic puff can be provided with both of an improved texture and an improved appearance. - To this end, preferably, the
moisturizer application regions 221 and themoisturizer non-application regions 222 are evenly arranged over the entire surface layers 220. Therefore, instead of the arrangement of themoisturizer application regions 221 and themoisturizer non-application regions 222 in thecosmetic puff 200 as shown inFIG. 3 , for example, an arrangement shown inFIG. 5 may be used.FIG. 5 is a plan view of acosmetic puff 300 according to another embodiment of the present invention. - As shown in
FIG. 5 , thecosmetic puff 300 as a representative embodiment of the invention has surface layers 320 each includingmoisturizer application regions 321 to which a moisturizer is applied andmoisturizer non-application regions 322 or regions other than themoisturizer application regions 321. Thecosmetic puff 300 has an area in which themoisturizer application regions 321 and themoisturizer non-application regions 322 are alternately arranged in the directions of the width and the length of the cosmetic puff 200 (wherein the direction of the width is set to coincide with the horizontal direction inFIG. 5 ). Specifically, each of themoisturizer application regions 321 is defined as a rectangular region (typically a square region) having an application width d4 in the horizontal direction and an application width d5 in the vertical direction. Themoisturizer application regions 321 are arranged with pitches d6 in the horizontal direction and with pitches d7 in the vertical direction. Further, each of themoisturizer non-application regions 322 is defined as a region between adjacentmoisturizer application regions 321. Like in the case shown inFIG. 4 , the sheet thickness of themoisturizer application region 321 is rendered smaller than the sheet thickness of themoisturizer non-application region 322. By such arrangement of themoisturizer application regions 321 shown inFIG. 5 , a so-called “lattice pattern” or “checkered pattern” is formed. Themoisturizer application regions 321 and themoisturizer non-application regions 322 here are features that correspond to the “moisturizer application regions” and the “moisturizer non-application regions”, respectively, according to this invention. - As described above with reference to
FIGS. 3 to 5 , in this embodiment, the moisturizer application regions and the moisturizer non-application regions are preferably provided in the surface layers of the cosmetic puff. Applicants of this invention further found successfully that improvements in texture and appearance can both be realized at a higher level by defining the shape, dimensions, pitches or the like of the moisturizer application regions. - Specifically, applicants conducted quantitative evaluations of the texture and the appearance of the
moisturizer application regions 221 shown inFIG. 3 and themoisturizer application regions 321 shown inFIG. 5 in varying dimensions and pitches.

moisturizer application regions 221 shown inFIG. 3 are arranged to extend in the vertical direction, having the application width d1 of 2.0 mm and the pitches d3 of 1.0 mm. - As for the specimen of the comparative example 14, the specimen of the working example 1 is used as a base, and a moisturizer (glycerin:water=70% by weight:30% by weight) is applied to the both sides of the specimen at the rate of 20% by weight. Further, a plurality of the
moisturizer application regions 321 shown inFIG. 5 are arranged, having the application widths d4, d5 (d4=d5) of 2.0 mm, the horizontal pitches d6 of 3.0 mm and the vertical pitches d7 of 3.0 mm. - For evaluations on the criterion D (dry thickness), the thickness of each dry specimen (which corresponds to the sheet thickness h2 in
FIG. 4 ) is measured by using a portable thickness gage (CR-10A of Daiei Kagaku Seiki Mfg. Co., Ltd.). For evaluations on the criterion E (flexural property), a value B (gf·cm2/cm) of the flexural property is obtained by using a flexural property measuring equipment (KES-FB2 ALTO-A of Kato Tech Co., Ltd.). -
FIG. 6 shows results of evaluation of each specimen in the working examples 11 to 16 and the comparative examples 11 to 14 in this embodiment on criteria D, E. From the evaluation results shown inFIG. 6 , evaluations are made as follows: - As fix the criterion D, the dry thickness of every specimen of the working examples 11 to 16 exceeds 1.2 mm, and it is thus verified that the specimens in the working examples 11 to 16 are kept bulky, compared with the specimens of the comparative examples 12 to 14 in which the dry thickness is far below the initial thickness (1.322 mm) of the comparative example 11. Therefore, the cosmetic puff can be improved in appearance (or provide a quality appearance).
- As for the criterion E, the value B (gf·cm2/cm) of the flexural property of every specimen of the working examples 11 to 16 and the comparative examples 12 to 14 is far below the value B (0.2300 gf·cm2/cm) of the comparative example 11. It is thus verified that improvement in texture is realized by application of a moisturizer.
- From the above-described evaluation results on the criteria D and E, it is quantitatively verified that improvements in texture and appearance can both be realized at a higher level by forming the cosmetic puff of materials corresponding to the specimens of the working examples 11 to 16.
- The specimens of the comparative examples 12 to 14 each have relatively small pitches, compared with the specimens of the working examples 11 to 16. Therefore, the pitches between adjacent moisturizer application regions are kept unchanged only shortly after application of the moisturizer, but the moisturizer may spread with the passage of time and reduce the pitches finally to almost zero (almost in the state of overall application). As a result, the dry thickness may be reduced. Therefore, if the initial pitches between adjacent moisturizer application regions can be kept unchanged even during use of the product by the user, the pitches and the application width of the moisturizer are not limited to the settings defined in the working examples 11 to 16, but can be appropriately set as necessary.
