Usually, the nonwoven sheet is wound around a roller. And a cosmetic puff is manufactured by pulling out the nonwoven fabric sheet from the roller and processing the pulled-out nonwoven fabric sheet. In this case, the pressure applied to the nonwoven fabric sheet wound around the center of the roller is greater than the pressure applied to the nonwoven fabric sheet wound around the outer periphery of the roller.
Since the spunlace nonwoven fabric sheet used in the cosmetic puff described in Patent Document 1 is tightly entangled with water by a water jet, the thickness of the nonwoven fabric sheet wound around the center side of the roller and the outer peripheral side of the roller Although there is not much difference in the thickness of the nonwoven fabric sheet wound around, the thickness (bulk) is limited. On the other hand, the nonwoven fabric sheet used in the cosmetic puff described in Patent Document 2 has a large thickness (bulk), but the thickness of the nonwoven fabric sheet wound around the center of the roller and the outer peripheral side of the roller. The difference in the thickness of the wound nonwoven fabric sheet is large. For this reason, it is necessary to provide a thickness (bulk) recovery device for recovering the thickness of the nonwoven fabric sheet drawn from the center side of the roller.
The present invention has been made in view of such points, and an object of the present invention is to provide a technique for reducing a difference in thickness (bulk) of an airlaid nonwoven fabric sheet drawn from a roller.

One invention relates to a cosmetic puff. The cosmetic puff of the present invention is preferably used as it is or when pressed against the face with a cosmetic liquid, powder, gel, cream or the like attached thereto.
The cosmetic puff of the present invention includes an air laid nonwoven fabric that includes pulp fibers and is manufactured by a known air laid method. A moisturizing liquid containing a moisturizing agent and water is applied to the surface of the airlaid nonwoven fabric sheet. The moisturizing liquid contains 4 to 59% by weight of water, preferably 10 to 50% by weight. The moisturizing liquid is preferably applied to both surfaces of the airlaid nonwoven sheet, but may be applied only to one surface. Examples of the “humectant” include glycerin, diglycerin, triglycerin, ethylene glycol, propylene glycol, 1.3-butylene glycol, liquid paraffin, squalane, petrolatum, olive oil, soybean oil, safflower oil, coconut oil, jojoba oil. , Almond oil, castor oil, coconut oil, mink oil, vitamin E, dimethyl silicone, silicone oil, modified silicone, sorbitol, sucrose, glucose, maltose, maltose, beeswax, hyaluronic acid, placenta extract, aloe extract, chamomile extract, For example, momonoha extract, collagen, loofah extract, hinoki chile and the like can be used.
In the present invention, the airlaid nonwoven fabric wound on the center side of the roll swells when the pulp absorbs water contained in the moisturizing liquid and increases in thickness (recovers bulk). On the other hand, the thickness of the airlaid nonwoven fabric wound on the outer peripheral side of the roll is equal or slightly reduced by the pulp absorbing water contained in the moisturizing liquid. Thereby, the airlaid nonwoven fabric pulled out from the roll has a large thickness (bulk), but the difference in thickness is reduced. Therefore, the quality of the cosmetic puff can be easily improved. Moreover, the moisture of the user's skin can be supplemented by the moisturizing liquid.
The air laid nonwoven fabric sheet includes a fold line that folds the air laid nonwoven sheet, a plurality of holes provided along the fold line, a first sheet portion that is one side of the fold line, and the other side of the fold line. And a second sheet portion which is a portion.
As a result, the first sheet portion and the second sheet portion can be separated along the folding line.

As an airlaid nonwoven fabric, it is preferable to use an airlaid nonwoven fabric sheet containing pulp fibers and hydrophobic synthetic fibers. The “hydrophobic synthetic fiber” includes various synthetic fibers having hydrophobicity. Typically, one or more of polyethylene terephthalate fiber (PET), polyester fiber, polypropylene fiber (PP), polyethylene fiber (PE), nylon fiber, etc. can be used as the hydrophobic synthetic fiber.
In this form, since the hydrophobic synthetic fiber is contained in the airlaid nonwoven fabric sheet, the desired water separation in the cosmetic puff can be ensured. Thereby, the discharge | release amount of a lotion can be optimized according to a user's putting power.

Furthermore, as the airlaid nonwoven fabric sheet, it is preferable to use an airlaid nonwoven fabric containing hydrophobic synthetic fibers in a proportion of 10 to 50% by weight.
By using an airlaid nonwoven fabric containing 10 to 50% by weight of a hydrophobic synthetic fiber, it is possible to increase the recovery rate after weighting when wet, the collective water separation rate, and the divided water separation rate. “Wet-weighted recovery rate when wet” is determined by the thickness when a predetermined force (also referred to as “load”) is applied in a wet state (when loaded) and the thickness when the application of the predetermined force is canceled. It is calculated and indicates the degree of thickness recovery when wet. The “collective water separation rate” indicates the amount of water (water separation degree) that is separated at a time when a predetermined force is applied in a wet state. The “divided water separation rate” indicates the amount of water (water separation degree) that is separated (water discharged) when a predetermined force is applied in a plurality of times in a wet state.

Moreover, as an airlaid nonwoven fabric, it is preferable to use the airlaid nonwoven fabric in which the fiber weight per unit length of the pulp fiber is set to 0.2 mg / m or more.
Pulp fibers in which the fiber weight per unit length is set to 0.2 mg / m or more have a strong skeleton structure with an average pore size (diameter of the void portion) of 100 μm or more. Thereby, the recovery rate after weighting at the time of wet, a collective water separation rate, and a division | segmentation water separation rate become high.

  Moreover, as an airlaid nonwoven fabric sheet, it is preferable to use the airlaid nonwoven fabric sheet in which the outer layer part of the at least one side is formed with the rayon fiber. Since the outer layer portion of the air laid nonwoven fabric is formed of rayon fibers, the touch when using the cosmetic puff becomes smooth.

  Moreover, as a makeup | decoration puff, it is preferable to comprise the distance between the edge of a 1st sheet | seat part, and a folding line longer than the distance between the edge of a 2nd sheet | seat part, and a folding line. .

  In addition, as a makeup puff, in a state where the first sheet portion and the second sheet portion are overlapped, a place away from the folding line on the edge side of the first sheet portion, and the second sheet portion It is preferable to join the part away from the folding line on the edge side with a joint part.

  Moreover, as a cosmetic puff, it is preferable that a joining part joins a 1st sheet | seat part and a 2nd sheet | seat so that peeling is possible.

  In addition, as the cosmetic puff, it is preferable that a finger insertion space for inserting a user's finger is formed between the joint portion and the folding line by the first sheet portion and the second sheet portion.

Other invention is related with the manufacturing method of the cosmetic puff which manufactures a cosmetic puff using the airlaid nonwoven fabric containing the pulp fiber currently wound by the roll.
The present invention includes a drawing step of drawing an air laid nonwoven sheet containing pulp fibers from a roll, and a processing step of manufacturing a cosmetic puff by processing the air laid nonwoven sheet drawn from the roll. The processing step includes an application step of applying a moisturizing liquid containing a moisturizing agent and water to the surface of the airlaid nonwoven fabric sheet drawn from the roll. A coating process can be arrange | positioned in the suitable location in a processing process. In the application step, it is preferable to apply the moisturizing liquid to both surfaces of the air laid nonwoven sheet, but it may be applied to only one surface. As a method for applying the moisturizing liquid to the surface of the air laid nonwoven fabric sheet, various known application methods can be used. As the “humectant”, the aforementioned humectant can be used.
In the present invention, a moisturizing liquid containing a moisturizing agent and water is applied to the surface of the airlaid nonwoven fabric sheet containing pulp fibers drawn from the roll. As a result, the air-laid nonwoven fabric wound around the center of the roll swells when the pulp absorbs the water contained in the moisturizing liquid, and the thickness increases (the bulk is restored). On the other hand, the thickness of the airlaid nonwoven fabric wound on the outer peripheral side of the roll is equal or slightly reduced by the pulp absorbing water contained in the moisturizing liquid. Therefore, a cosmetic puff can be manufactured using an air-laid nonwoven fabric with a simple structure and a desired thickness (bulk) with little difference in thickness. Moreover, the moisture of the user's skin can be supplemented by the moisturizing liquid.
The air laid nonwoven fabric sheet includes a fold line that folds the air laid nonwoven sheet, a plurality of holes provided along the fold line, a first sheet portion that is one side of the fold line, and the other side of the fold line. And a second sheet portion which is a portion.
As a result, the first sheet portion and the second sheet portion can be separated along the folding line.

  In the application step, a moisturizing liquid containing 4 to 59% by weight, preferably 10 to 50% by weight of water is applied. When the blending ratio of water is too small, the increase rate (recovery rate) of the thickness (bulk) of the airlaid nonwoven fabric wound around the center of the roll becomes small. On the other hand, if the mixing ratio of water is too high, the rate of increase (recovery rate) of the thickness (bulk) of the airlaid nonwoven fabric wound on the center side of the roll increases, but the water tends to evaporate. Can not be maintained. By using the moisturizing liquid containing water at such a blending ratio, it is possible to reduce the difference in thickness of the airlaid nonwoven fabric drawn from the roll while maintaining softness.

  Moreover, it is preferable to use the airlaid nonwoven fabric in which the fiber weight per unit length of the pulp fiber is set to 0.2 mg / m or more. Pulp fibers in which the fiber weight per unit length is set to 0.2 mg / m or more have a strong skeleton structure with an average pore size (diameter of the void portion) of 100 μm or more. Thereby, the recovery rate after weight at the time of wet, a collective water separation rate, and a division | segmentation water separation rate become high.

  Moreover, it is preferable to use an airlaid nonwoven fabric sheet containing pulp fibers and hydrophobic synthetic fibers. As the hydrophobic synthetic fiber, the above-described hydrophobic synthetic fiber can be used. Preferably, the blending ratio of the hydrophobic synthetic fiber is set to 10 to 50% by weight. Thereby, the desired water separation in a cosmetic puff can be ensured, and the discharge amount of the lotion can be optimized according to the user's putting power.

  Further, as a method for producing a cosmetic puff, the distance between the edge of the first sheet portion and the fold line is configured to be longer than the distance between the edge of the second sheet portion and the fold line. It is preferable.

  In addition, as a method for manufacturing a cosmetic puff, in a state where the first sheet portion and the second sheet portion are overlapped, a place away from the folding line on the edge side of the first sheet portion, It is preferable to join the part away from the folding line on the edge side of the sheet part by the joining part.

  Moreover, as a manufacturing method of a cosmetic puff, it is preferable that a joining part joins a 1st sheet | seat part and a 2nd sheet | seat so that peeling is possible.

  Moreover, as a manufacturing method of the cosmetic puff, it is preferable to form a finger insertion space for inserting a user's finger between the joint portion and the fold line by the first sheet portion and the second sheet portion.

  By using the present invention, it is possible to easily provide a cosmetic puff using an airlaid nonwoven fabric having a desired thickness (bulk) and a small difference in thickness.

It corresponds to the “airlaid nonwoven fabric sheet” of the invention. The pulp fiber and polyethylene terephthalate fiber forming the inner layer sheet 120A correspond to the “pulp fiber” and “hydrophobic synthetic fiber” of the present invention, respectively.

As shown in FIG. 2, the sheet 120 used in the present embodiment has edge portions (short sides) 120a and 120c having a length M1, and edge portions (long sides) having a length L1 (L1> M1). It is formed in a square having 120b and 120d (for example, a square of 60 mm × 140 mm). The sheet 120 is folded along a line 120h connecting points obtained by dividing the edges 120b and 120d by [L2: L3] (L2> L3) (hereinafter, the line 120h is referred to as a “folding line 120h”). In the present embodiment, the sheet 120 includes a first sheet portion 121 that is a portion on one side from the fold line 120h and a second sheet portion 122 that is a portion on the other side from the fold line 120h. That is, the first sheet portion 121 includes edge portions (long sides) 120b2 and 120d1 having a length L2, edge portions (short sides) 120c having a length M1 (M1 <L2), and a folding line 120h having a length M1.

In addition, a plurality of holes 120H are formed in the sheet 120 along the folding line 120h. As the hole 120H, a perforation formed by a perforation processing apparatus is typically used. By the hole 120H, the first sheet portion 121 and the second sheet portion 122 can be separated along the folding line 120h. The shape and interval of the holes 120H are set as appropriate. The hole 120H corresponds to “a plurality of holes formed along the folding line” of the present invention.

  In the present embodiment, the first sheet portion 121 and the second sheet portion 122 are overlapped by folding the sheet 120 at the position of the folding line 120h. Here, the distance L2 between the edge 120c of the first sheet portion 121 and the folding line 120h is longer than the distance L3 between the edge 120a of the second sheet portion 122 and the folding line 120h (L2>). L3). Therefore, as shown in FIGS. 4 and 5, in the state where the first sheet portion 121 and the second sheet portion 122 are overlapped, the edge portion 120 a of the second sheet portion 122 is the first portion. The sheet portion 121 is disposed at a position separated by a distance n1 (= L2-L3) on the folding line 120h side from the edge portion 120c of the sheet portion 121. The distance n1 is set to 1 to 3 mm, for example. The edge portion 120c of the first sheet portion 121 is “the edge portion of the first sheet portion facing the folding line”, and the edge portion 120a of the second sheet portion 122 is “second edge”. The edge of the sheet portion on the side facing the fold line ”. Further, the edge portions 120b2 and 120d1 of the first sheet portion 121 are “the edge portions of the first sheet portion that extend from both end portions of the fold line in the direction intersecting with the fold line”. The edge portions 120b1 and 120d2 of the sheet portion 122 are “edge portions of the second sheet portion extending from both end portions of the fold line in a direction intersecting with the fold line”.

In a state where the first sheet portion 121 and the second sheet portion 122 are overlapped, the edge portion 120c side of the first sheet portion 121 and the edge portion 120a side of the second sheet portion 122 (separate from the folding line 120h). Are joined). In this case, a finger insertion space 111X (FIG. 6) having both ends opened between the first sheet portion 121 and the second sheet portion 122 by the fold line 120h and the joining portion 111 and into which at least one finger can be inserted. , See FIG. 7) are formed so as to be formed along the folding line 120h. Here, the interval between the finger insertion spaces 111X is determined by a line 111a that is parallel to the fold line 120h and passes through the joint portion 111 and is closest to the fold line 120h. In the present specification, a line that is parallel (including substantially parallel) to the center line of the finger insertion space 111X and that passes through the joint portion 111 and is closest to the center line of the finger insertion space 111X is referred to as a “joint line”. . In the present embodiment, the line 111a shown in FIG. 4 corresponds to the “joining line”. In the present embodiment, the center line of the finger insertion space 111X is parallel (including substantially parallel) to the direction in which the folding line 120h extends. Hereinafter, the line 111a is referred to as a “joining line 111a”. In the present embodiment, the joining portion 111 that joins the first sheet portion 121 and the second sheet portion 122 is formed so that the distance L4 between the joining line 111a and the folding line 120h is equal to or greater than the set distance. Has been. As the set distance, for example, an insertion space 111X in which an index finger or an index finger and a middle finger can be inserted is formed by the first sheet portion 121 and the second sheet portion 122 between the joining line 111a and the folding line 120h. Distance is used. Thereby, for example, as shown in FIG. 6, the putting can be performed with the index finger and the middle finger inserted into the finger insertion space 111 </ b> X of the makeup puff 110.
In the present embodiment, the direction of the finger insertion space 111X (the direction of the center line of the finger insertion space 111X), that is, the direction of the folding line 120h (the direction in which the folding line 120h extends) is “one direction” of the present invention. Corresponding to The direction intersecting (orthogonal) with the direction of the finger insertion space 111X, that is, the direction intersecting (orthogonal) with the direction of the folding line 120h corresponds to the “direction intersecting with one direction” of the present invention. The direction of the return line 120h is, for example, the direction of a line connecting both ends of the return line 120h.

Moreover, in this Embodiment, the 1st sheet | seat part 121 and the 2nd sheet | seat part 122 are joined so that peeling is possible. Various joining methods can be used as a method of joining the first sheet portion 121 and the second sheet portion 122 in a peelable manner. Preferably, a hot embossing method or a hot melt bonding method is used.
The hot embossing method is a method of performing embossing while applying heat. For example, heat is applied to a predetermined portion (embossed portion) on one side of the laminate in which the first sheet portion 121 and the second sheet portion 122 are overlapped, and force is applied to the laminate. A predetermined portion of the other surface is pushed up. Thereby, a convex processed shape (characters or patterns) is formed on the other side of the laminate, and the first sheet portion 121 and the second sheet portion 122 are thermocompression bonded at the embossed portion. When the 1st sheet part 121 and the 2nd sheet part 122 are joined by hot embossing, since a lotion etc. become difficult to penetrate to a joined part, a fall of joining power of joined part 111 can be controlled. The embossed shape also improves the appearance of the cosmetic puff. The emboss shape is appropriately selected in consideration of the bonding force of the bonding portion 111, the visual effect, and the like.
The hot melt bonding method is a method of bonding using a hot melt adhesive that melts at a high temperature and hardens and adheres when the temperature is lowered. For example, after applying a melted hot melt adhesive to the joining portion between the first sheet portion 121 and the second sheet portion 122, the first sheet portion 121 and the second sheet portion 122 are joined by cooling. In the case where the first sheet portion 121 and the second sheet portion 122 are detachably joined using a hot melt bonding method, an easily peelable hot melt adhesive is used.
In this embodiment mode, the peelable bonding portion 111 is formed using a hot embossing method.
In FIG. 4, the joint portion 111 that is continuous along the direction of the fold line 120 h is formed. However, a plurality of joint portions that are separated from each other may be formed along the direction of the fold line 120 h. it can. In this specification, the description “along the direction” typically means “parallel to (including substantially parallel to) the direction”. For example, a plurality of joints are formed along one row parallel to the direction of the folding line 120h. Alternatively, a plurality of first joints along the first row parallel to the direction of the fold line 120h and a plurality of second joints along the second row may be combined with the first joint and the second It forms so that a junction part may be alternately arrange | positioned along the direction of the folding line 120h. In this way, by forming the joints at locations apart from each other along the fold line, even if the joint part on the end side is peeled off, the joint part adjacent to the joint part on the end side is peeled off in conjunction with it. Can be prevented.
The shape, arrangement location, interval, and the like of the joint are set as appropriate.

In the present embodiment, the first sheet portion 121 and the second sheet portion 122 are closer to the folding line 120h than the edge portion 120c of the first sheet portion 121 and the edge portion 120a of the second sheet portion 122. It is joined at a distant place. In the present embodiment, since the edge portion 120a of the second sheet portion 122 is disposed on the folding line 120h side from the edge portion 120c of the first sheet portion 121, the first sheet portion 121 and the second sheet portion. 122 is joined at a location away from the edge 120a of the second sheet portion 122 toward the folding line 120h. That is, the joining portion 111 that joins the first sheet portion 121 and the second sheet portion 122 is formed at a position separated from the edge 120a of the second sheet portion 122 on the folding line 120h side by a distance n2 or more. Yes. For example, 1 to 3 mm is set as the distance n2.
Thereby, since the edge 120c of the 1st sheet part 121 and the part between the edge 120a of the 2nd sheet part 122, and the junction part 111 are not joined, the edge part 120c side of the 1st sheet part 121 is carried out. This part and the part on the edge 120a side of the second sheet part 122 can be easily grasped with a finger. Therefore, the edge part 120c side portion of the first sheet part 121 and the edge part 120a side part of the second sheet part 122 can be easily pulled in the direction of separating, and the first sheet part 121 and the second sheet part 121 The sheet portion 122 can be easily peeled off at the joint portion 111.
In the present embodiment, the edge portion 120c of the first sheet portion 121 and the edge portion 120a of the second sheet portion 122 are arranged so as to be shifted in a direction intersecting the direction of the finger insertion space. As a result, the edge portion 120c side portion of the first sheet portion 121 and the edge portion 120a side portion of the second sheet portion 122 can be more easily grasped with the fingers, and the first sheet portion 121 and the first sheet portion 121 The two sheet portions 122 can be more easily separated at the joint portion 111.

In step S6 (cutting step), the sheet 100 in which the first sheet portion 121 and the second sheet portion 122 are joined by the joining portion 111 is cut to a predetermined length to obtain a cosmetic puff 110 (FIG. 4, FIG. 4). (See FIG. 5).
In the present embodiment, the “processing step” of the present invention is constituted by the steps S2, S4, S5, and S6. The coating step S3 can be arranged at an appropriate location in the processing step.

The cosmetic puff 110 according to the first embodiment is configured by one sheet 120, but may be configured by a plurality of sheets.
A makeup puff 210 according to the second embodiment will be described with reference to FIGS. 11 and 12. The cosmetic puff 210 of the present embodiment is composed of a first sheet 221 and a second sheet 222. The first sheet 221 and the second sheet 222 are air laid nonwoven sheets having an inner layer sheet 120A and an outer layer sheet 120B, similar to the sheet 120 used in the cosmetic puff 110 of the first embodiment. In the present embodiment, the first sheet 221 has a rectangular shape having edges (short sides) 221a and 221c having a length M1 and edges (long sides) 221b and 221d having a length L2 (L2> M1). Is formed. The second sheet 222 has a rectangular shape having edges (short sides) 222a and 222c having a length M1, and edges (long sides) 222b and 222d having a length L3 (L2> L3, L3> M1). Is formed. A moisturizing liquid 222X containing a moisturizing agent and water is applied to the surfaces on both sides of the first sheet 221 and the second sheet 222. By applying the moisturizing liquid 222X, the first sheet 221 and the second sheet 222 have a moisturizing function and flexibility. Further, as will be described later, the difference in thickness (bulk) of the sheet drawn from the roll (see FIG. 1) 10 is reduced by the water contained in the moisturizing liquid 222X.
In the present embodiment, the first sheet 221 corresponds to the “first airlaid nonwoven fabric sheet” or “first airlaid nonwoven fabric sheet portion” of the present invention, and the second sheet 222 corresponds to the “second airlaid nonwoven fabric portion” of the present invention. The sheet 210 composed of the first sheet 221 and the second sheet 222 corresponds to the “airlaid nonwoven sheet” or “second airlaid nonwoven sheet portion” and corresponds to the “airlaid nonwoven sheet” of the present invention.

  The first sheet 221 and the second sheet 222 are overlapped. For example, the corresponding edge portion 221a of the first sheet 221 and the corresponding edge portion 222a of the second sheet 222 are overlapped so as to face (oppose) each other. Here, the length L2 of the edge portions 221b and 221d intersecting (orthogonal) the edge portion 221a of the first sheet 221 is the edge portion intersecting (orthogonal) the edge portion 222a of the second sheet 222. It is longer than the length L3 of 222b and 222d (L2> L3). For this reason, when the first sheet 221 and the second sheet 222 are overlapped so that the corresponding edges 221a and 222a face each other (opposite), the second sheet as shown in FIG. The edge 222c of the 222 is disposed at a position separated from the edge 221c of the first sheet 221 on the edge 222a (or 221a) side by a distance n1 (= L2-L3). The distance n1 is set to 1 to 3 mm, for example. The edge part 221c of the first sheet part 221 is an edge part of the first sheet part 221 on the side facing the edge part 222a. The edge 222c of the second sheet 222 is an edge of the second sheet 222 on the side facing the edge 222a.

And the 1st sheet | seat 221 and the 2nd sheet | seat 222 are joined in the state piled up. In the present embodiment, the first sheet 221 and the second sheet 222 are joined so that both ends are open and a finger insertion space into which at least one finger can be inserted is formed. For example, the direction of the edge 221a (or the edge 222a) so that the finger insertion space is formed along the direction of the edge 221a of the first sheet 221 (or the edge 222a of the second sheet 222). The first sheet 221 and the second sheet 222 are joined at a location separated in a direction intersecting with. In the present embodiment, the first joining portion 211 is formed on the edge portion 221a of the first sheet 221 and the edge portion 222a side of the second sheet 222, and the edge portion 221c side (one of the first sheets 221) A second bonding portion 212 is formed on the edge portion 221 a and the edge portion 222 c of the second sheet 222 (on the edge portion facing one edge portion 222 a).
In the present embodiment, the first insertion line is parallel to (including substantially parallel to) the center line of the finger insertion space (the opposite edge 221a of the first sheet 221 or the edge 222a of the second sheet 222). Among the lines passing through the joint part 211, the line closest to the center line of the finger insertion space, that is, the line 211a farthest from the edge part 221a or the edge part 222a (longest distance) is referred to as a first joint line. . In addition, a line that is parallel to (including substantially parallel to) the center line of the finger insertion space and passes through the second joint portion 212 and is closest to the center line of the finger insertion space, that is, the edge 221a or the edge The line 212a closest to the portion 222a (the shortest distance) is referred to as a second joining line. In the present embodiment, the first joint portion 211 and the second joint portion 212 are formed so that the distance L4 between the first joint line 211a and the second joint line 212a is equal to or greater than the set distance. As the set distance, for example, the first joint portion 211 and the second joint portion 212 form an insertion space in which the index finger or the index finger and the middle finger can be inserted between the first sheet 221 and the second sheet 222. Distance is used. Thereby, for example, the putting can be performed with the index finger and the middle finger inserted in the finger insertion space of the makeup puff 210.
In the present embodiment, the direction of the center line of the finger insertion space, that is, the direction of one edge 221a of the first sheet 221 or the edge 222a of the second sheet 222 is “one direction” of the present invention. Correspond. Further, the direction intersecting (orthogonal) with the center line of the finger insertion space, that is, the direction intersecting (orthogonal) with the direction of the edge 221a or the edge 222a is the “direction intersecting with one direction” of the present invention. Correspond. The direction of the edge 221a (edge 222a) is, for example, the direction of a line connecting both ends of the edge 221a (222a).

Moreover, the 1st sheet | seat 221 and the 2nd sheet | seat 222 are joined so that peeling is possible. As a method of joining the first sheet 221 and the second sheet 222 in a peelable manner, for example, the above-described hot embossing method or hot melt bonding method can be used. In this embodiment, a hot embossing method is used.
The first sheet 221 and the second sheet 222 are joined by the peelable first joining portion 211 and the second joining portion 212, whereby the first sheet 221 and the second sheet 222 are joined to each other. It can be peeled off at the junction 211 and at one or both of the second junction 212.
The first joint portion 211 and the second joint portion 222 may be formed continuously along one row as in the second embodiment, or may be separated by a set distance along one row. The plurality of joints along the first row that are parallel (including substantially balanced) and the plurality of joints along the second row are alternately arranged along the direction of the row. You may form so that it may be arrange | positioned. Thereby, it is possible to prevent the first sheet 212 and the second sheet 222 from being peeled off when the joint portion on the end side is peeled off during use of the cosmetic puff.

In the present embodiment, the first joining portion 211 (one joining portion) is formed in the vicinity of the edge portion 221 a of the first sheet 221 and the edge portion 222 a of the second sheet 222. On the other hand, the second bonding portion 212 (the other bonding portion) has an edge 221a (or second) of the first sheet 221 from the edge 221c of the first sheet 221 and the edge 222c of the second sheet 222. The sheet 222 is formed at a position away from the edge 222a) side. Here, in the present embodiment, the edge 222c of the second sheet 222 is disposed closer to the edge 212a (or 222a) than the edge 221c of the first sheet 221. For this reason, the 2nd junction part 212 is formed in the location away from the edge part 212c of the 2nd sheet | seat 222 to the edge part 212a (or 222a) distance n2. That is, the edge 221a of the first sheet 221 and the edge 222a of the second sheet 222 (one edge in the direction intersecting the center line of the finger insertion space) and the first joining line 211 (one) Between the edge 221c of the first sheet 221 and the edge 222c of the second sheet 222 (the edge in the direction on the other side of the direction intersecting the center line of the finger insertion space). The first joint portion 211 and the second joint portion 212 are formed so as to be shorter than the distance between the first joint line 212 and the second joint line 212 (the other joint line). The distance n2 is set to 1 to 3 mm, for example.
In the present embodiment, the edge 221c of the first sheet 221 and the edge 222c of the second sheet 222 and the second joint 212 are not joined, so the edge 221c of the first sheet 221 is not joined. The portion on the side and the portion on the edge 222c side of the second sheet 222 can be easily grasped with a finger. Accordingly, the first sheet 221 and the second sheet 222 are pulled to the second bonding portion 212 by pulling the edge 221 c side portion of the first sheet 221 and the edge portion 222 c side portion of the second sheet 222. Can be peeled off.
Further, in the present embodiment, the first joint portion 211 is formed in the vicinity of the edge portion 221 a of the first sheet 221 and the edge portion 222 a of the second sheet 222.

In the case where the first sheet 221 and the second sheet 222 are preferentially peeled off from the location of the second joint portion 212, the first joint portion 211 is used as a bonding force of the second joint portion 212. It is preferable to form a joint having a high joining force. In addition, for example, it is preferable to provide an instruction portion such as a mark or a display on the second joint portion 212 side and guide the first sheet 221 and the second sheet 222 to be peeled from the joint portion 212.
In the present embodiment, the edge 222 c of the second sheet 222 is closer to the edge 222 a of the second sheet 222 or the edge 221 a of the first sheet 221 than the edge 221 c of the first sheet 221 ( It is arranged at a location distant from the center of the finger insertion space. Thereby, the operation of gripping the portion on the edge 221c side of the first sheet 221 and the portion on the edge 221c side of the second sheet 222 with a finger is easier.

From the measurement results of Examples 1 to 3 and Comparative Examples 1 to 7 shown in FIG.
When the nonwoven fabric sheet is coated with a moisturizing liquid and then wound around a roller and pulled out from the roller to process the nonwoven fabric sheet (winding after coating), either the airlaid nonwoven fabric sheet of Comparative Example 5 or the air-through nonwoven fabric sheet of Comparative Example 7 Even if is used, the “winding core thickness (after processing)” is 80% or less (the difference is 20% or more) of the “outside winding thickness (after processing)”. Furthermore, when the spunlace nonwoven fabric sheet of Comparative Example 6 is used, both “outer winding thickness (after processing)” and “winding core thickness (after processing)” are small.
Further, even when the air laid nonwoven sheet coated with the moisturizing liquid is processed after applying the moisturizing liquid to the surface of the air laid nonwoven sheet pulled out from the roller, as in Comparative Example 1, (glycerin: water = 100% by weight: When a moisturizing liquid having a blending ratio of 0% by weight is used, the difference between the “outer winding thickness (after processing)” and the “winding core thickness (after processing)” is large (20% or more). On the other hand, when a moisturizing liquid having a blending ratio of (glycerin: water = 0% by weight: 100% by weight) as in Comparative Example 4 was used, “outer winding thickness (after processing)” and “winding core thickness ( The difference in “after processing” is small (20% or less). However, since there is much water contained in the moisturizing liquid, the softness cannot be maintained when the water is naturally dried. From the measurement results shown in FIG. 13, the range of (glycerin: water = 100% by weight: 0% by weight) (Comparative Example 1) to (glycerin: water = 97% by weight: 3% by weight) (Comparative Example 2). When a moisturizing liquid having a blending ratio of water, that is, a moisturizing liquid with a water blending ratio (0 to 3% by weight) is used, the “outer winding thickness (after processing)” and “winding core thickness” The difference of “S (after processing)” is large (20% or more). Further, a moisturizing liquid having a blending ratio in the range of (glycerin: water = 40% by weight: 60% by weight) (Comparative Example 3) to (glycerin: water = 0% by weight: 100% by weight) (Comparative Example 4) is used. In this case, the difference between the “outer winding thickness (after processing)” and “winding core thickness (after processing)” is small (20% or less), but the softness after water is naturally dried must be maintained. I can't. In addition, the moisturizing liquid having a blending ratio in the range of (glycerin: water = 90% by weight: 10% by weight) to (glycerin: water = 50% by weight: 50% by weight) (Examples 1, 2, 3), that is, When using a moisturizing liquid whose water content is in the range of (10 wt% to 50 wt%), there is a difference between the "outside winding thickness (after processing)" and "winding core thickness (after processing)" Stable and small.
Therefore, as the moisturizing liquid to be applied to the surface of the airlaid nonwoven sheet drawn from the roll, (glycerin: water = 96% by weight: 4% by weight) to (glycerin: water = 41% by weight: 59% by weight), preferably , (Glycerin: water = 90% by weight: 10% by weight) to (glycerin: water = 50% by weight: 50% by weight). 59% by weight), and preferably by using a moisturizing liquid in the range of (10% by weight to 50% by weight), while maintaining the softness, the “wound outer thickness (after processing)” and “winding core” The difference in “thickness (after processing)” can be reduced.

The above has focused on reducing the difference between the “outer winding thickness (after processing)” and the “core thickness (after processing)”, that is, the difference in the thickness of the nonwoven fabric sheet drawn from the roll. Water separation performance when putting a user's skin in a state of being impregnated (water-retained) with water or the like is also an important function of a cosmetic puff.
Therefore, in order to quantitatively confirm the water separation performance of the cosmetic puff, for Examples 4 to 10 and Comparative Examples 8 and 9, recovery rate after weighting when wet, collective water separation rate, split water separation rate (release of lotion, etc.) Amount) was measured.
Note that the “recovery rate after weighting when wet” indicates the degree of recovery of the thickness of the evaluation piece when a predetermined force is applied to the wet evaluation piece and then the application of the predetermined force is canceled. The “divided water separation rate” indicates the amount of water (water separation degree) that is separated (released) from the evaluation piece when a predetermined force is applied to the evaluation piece in a wet state in a plurality of times. The “collective water separation rate” indicates the amount of water (degree of water separation) that is separated from the evaluation piece at a time when a predetermined force is applied to the evaluation piece in the wet state.

The recovery rate after weighting when wet, split water separation rate, and batch water separation rate were measured by the following methods.
(Recovery rate after weighting when wet)
For each evaluation piece in a wet state (in which 2 ml of test solution is impregnated) with a size of [50 mm × 50 mm] using a small thickness measuring instrument (manufactured by Daiei Kagaku Seiki Seisakusho, model: CR-10A) The first pressure (1.96 kPa (20 gf / cm2)) and the second pressure (3.92 kPa (40 gf / cm2)) are applied by a presser foot (1 cm2 (φ11.28 mm)), and the thickness is measured. did. The measured thickness value when the first pressure is applied is Da, the measured thickness value when the second pressure is applied is Db, and the measured thickness value when the first pressure is applied again is Dc. Using the formula [(Dc−Db) / Db × 100], the weighted recovery rate (%) when wet was calculated.

(Split water separation rate)
A filter paper having a dimension of [50 mm × 50 mm] is overlaid on each evaluation piece in a wet state (a state in which 2 ml of test liquid is impregnated) having a dimension of [50 mm × 50 mm], and then a predetermined pressure [34.6 kgf / cm2] was applied in three stages. And after each pressure application, the moisture content which water-separated to the filter paper from each evaluation piece was computed.
Specifically, in the first step, the weight Wd of the test solution and the weight We of the 10 filter papers are measured in advance, and 10 sheets of the filter paper (weight We) are superimposed on each wet evaluation piece. . Next, a predetermined pressure [34.6 kgf / cm 2] was applied from above the filter paper for 5 seconds, and then the weight Wf of 10 filter papers was measured. Then, the first water separation rate (%) was calculated using the equation [(Wf−We) / Wd × 100].
In a second step subsequent to the first step, the weight Wg of 10 new filter papers was measured, and the 10 filter papers (weight Wg) were overlaid on each evaluation piece obtained in the first step. Next, a predetermined pressure [34.6 kgf / cm 2] was applied from above the filter paper for 5 seconds, and then the weight Wh of 10 filter papers was measured. And the water separation rate (%) of the 2nd time was computed using Formula [(Wh-Wg) / Wdx100].
In a third step following the second step, the weight Wi of 10 new filter papers was measured, and the 10 filter papers (weight Wi) were overlaid on each evaluation piece obtained in the second step. Next, a predetermined pressure [34.6 kgf / cm 2] was applied from above the filter paper for 5 seconds, and then the weight Wj of 10 filter papers was measured. And the water separation rate (%) of the 3rd time was computed using Formula [(Wj-Wi) / Wdx100].

(Collective water separation rate)
A filter paper having a size of 50 × 50 mm is placed on each evaluation piece in a wet state (in which 2 ml of test solution is impregnated) having a size of 50 × 50 mm, and then a predetermined pressure (17.5 kgf / cm 2) is applied. . And the moisture content which water-separated to the filter paper from each evaluation piece was computed. Specifically, the weight Wa of the test liquid and the weight Wb of 10 filter papers were measured in advance, and 10 sheets of filter paper (weight Wb) were stacked on each wet evaluation piece. Next, after applying the predetermined pressure (17.5 kgf / cm 2) for 15 seconds from above the filter paper, the weight Wc of 10 filter papers was measured. And the collective water separation rate (%) was computed by the formula shown by [(Wc−Wb) / Wa × 100].

The measurement results of Examples 4 to 10 and Comparative Examples 8 and 9 are shown in FIG. From the measurement results shown in FIG. 14, the following evaluation is made.
(Evaluation result of recovery rate after weighting when wet)
Each of the test pieces of Examples 4 to 10 has a wet weighted recovery rate of 7% or more, and Comparative Examples 8 and 9 have a wet weighted recovery rate of less than 7%. That is, it was confirmed that Examples 4 to 10 were superior in recovery performance after weighting when wet compared to Comparative Examples 8 and 9. Thereby, for example, when putting using a cosmetic puff impregnated with lotion, a sufficient amount of the lotion can be secured. Moreover, since the release of the lotion is good, the lotion is not wasted and economical.
(Evaluation result of collective water separation rate)
The collective water separation rates of Examples 4 to 10 are both 75% or more, and the collective water separation rates of Comparative Examples 8 and 9 are both less than 75%. That is, it was confirmed that Examples 4 to 10 were superior in collective water separation performance to Comparative Examples 8 and 9. Thereby, for example, when putting using a cosmetic puff impregnated with lotion, a sufficient amount of the lotion can be secured even when putting with a light force. In other words, it is not necessary to perform putting with such a strong force that puts a burden on the skin.
(Evaluation result of split water separation rate)
In Examples 4 to 10, the (first time + second time) water separation rate is 85% or more, and the (first time + second time + third time) water separation rate is 90% or more. In Comparative Examples 8 and 9, the water separation rate is less than 85% (first time + second time), and the water separation rate is less than 90% (first time + second time + third time). That is, it was confirmed that Examples 4 to 10 were superior in water separation performance in the division compared to Comparative Examples 8 and 9. As a result, for example, when putting in multiple times using a cosmetic puff impregnated with lotion, it is possible to continue the state in which the amount of the lotion is secured. The skin moisture content can be increased by putting the skin lotion several times and applying the lotion.

As described above, when the cosmetic puff impregnated with the lotion is put on the user's skin by using the airlaid nonwoven fabric corresponding to Examples 4 to 10, the lotion according to the putting power The release amount can be optimized.
Specifically, each of the airlaid nonwoven fabric sheets corresponding to Examples 4 to 10 contains pulp fibers having a fiber weight per unit length of 0.20 mg / m or more. Such a pulp fiber has an average pore size (diameter of the space between the fibers) of 100 μm or more and a strong skeletal structure, so that it is possible to increase the recovery rate after wet weighting, the collective water separation rate, and the divided water separation rate. Thereby, the lotion retained in the space portion between the fibers can be gradually discharged to the outer layer portion.
Moreover, all the air-laid nonwoven fabric sheets corresponding to Examples 5 to 9 contain polyethylene terephthalate fibers in a proportion of 10 to 50% by weight. Thereby, the recovery rate after weighting at the time of wet, a collective water separation rate, and a division | segmentation water separation rate can further be raised. Therefore, the effect of gradually discharging the skin lotion retained in the space between the fibers to the outer layer portion can be further enhanced.
Moreover, the air-laid nonwoven fabric sheet corresponding to Examples 4 to 10 has an outer layer portion containing rayon fibers. Thereby, the touch at the time of use of a cosmetic puff becomes smooth. In addition, any one outer layer part of outer layer parts can also be comprised with a rayon fiber.

The air laid nonwoven fabric sheet contains a binder. As the binder, styrene-butadiene rubber is typically used. Moreover, it is preferable to set the mixing ratio of the binder contained in the air laid nonwoven fabric sheet to 5 to 15 weight percent. When the mixing ratio of the binder is less than 5 percent by weight, the recovery rate after weighting when wet is lowered, and the first water separation amount is increased. On the other hand, if the mixing ratio of the binder exceeds 15% by weight, the material becomes hard and is not suitable for a cosmetic puff.
Moreover, it is preferable that the air-laid nonwoven fabric sheet includes polyethylene terephthalate fibers which are hydrophobic synthetic fibers. The content ratio of the polyethylene terephthalate fiber is preferably set to 10 to 50 weight percent. When the content ratio of the polyethylene terephthalate fiber exceeds 50% by weight, most of the absorbed skin water is released by the first putting. Furthermore, the amount of polyethylene terephthalate fiber increases, resulting in an increase in cost. Other hydrophobic synthetic fibers may be used in place of the polyethylene terephthalate fiber, or may be added to the polyethylene terephthalate fiber. As other hydrophobic synthetic fibers, for example, polyester fibers, polypropylene fibers (PP), polyethylene fibers (PE), and nylon fibers can be used.

Each configuration described in the embodiment can be used alone, or a plurality of appropriately selected configurations can be combined.
The moisturizing liquid is applied to the surfaces on both sides of the air laid nonwoven sheet, but it may be applied to at least one surface of the air laid nonwoven sheet.
Although the outer layer portion is provided on both sides of the inner layer portion, the outer layer portion only needs to be provided on at least one side of the inner layer portion. Furthermore, the outer layer portion can be omitted.
Although the first sheet portion 121 and the second sheet portion 122 (or the first sheet 221 and the second sheet 222) having different shapes are used, the first sheet portion and the second sheet portion having the same shape are used. A sheet portion (or a first sheet and a second sheet) can also be used.
