By the way, in order to give appearance and a high-class feeling, there is a demand for the development of a cosmetic puff displaying decorative patterns (for example, symbols, characters, geometric patterns, characters) on the surface. As a method of displaying the decorative pattern on the surface of the cosmetic puff, a method of forming a plurality of protrusions or recesses on the surface of the cosmetic puff corresponding to the decorative pattern (generally, “embossing method”) Can be used).
As a method for forming the recesses on the surface of the cosmetic puff, for example, the method described in Patent Document 1 can be used. However, when the method described in Patent Document 1 is used, since the concave portion is firmly formed on the surface of the cosmetic puff, the water separation when the cosmetic puff is impregnated with lotion or the like is good. Absent.
The present invention was devised in view of such points, and is a technique capable of obtaining a cosmetic puff having a plurality of recesses on the surface while ensuring a desired water separation upon impregnation with skin lotion or the like. The purpose is to provide.

The cosmetic puff of the first invention is constituted by an airlaid nonwoven fabric sheet produced by a known airlaid method. The airlaid nonwoven sheet includes pulp fibers. This air laid nonwoven fabric sheet has a plurality of recesses formed on one of the opposing surfaces. A recessed part may be formed in one whole surface of an airlaid nonwoven fabric sheet, and may be formed in the one part area | region of one surface. If a recessed part is formed in the predetermined area | region of one surface of the air laid nonwoven fabric sheet, the surface of the said predetermined area | region will become an uneven surface. In this case, by appropriately setting the shape, size, arrangement position, etc. of the recesses, it is possible to display a decorative pattern on one side of the air-laid nonwoven fabric sheet, and to enhance the appearance, luxury, etc. of the cosmetic puff. it can.
Cosmetic puffs are often used in the state of being impregnated with lotion. Here, when the recessed part is formed firmly, when using it in the state impregnated with the skin lotion, desired water separation cannot be obtained. In particular, the first water separation amount (water discharge amount) after impregnating the skin lotion increases. The water separation of the sheet in the state where the skin lotion is impregnated can be evaluated using a wet weighted recovery rate indicating the degree of recovery of the wet sheet thickness. The recovery rate after wet weighting is obtained when a predetermined amount of test liquid is impregnated into a sheet evaluation piece of a predetermined size, and a predetermined force (also referred to as “load”) is applied to the sheet evaluation piece (when loaded). It is calculated by the thickness and the thickness when the application of the predetermined force is released. In the present invention, the recovery rate after load when wet is set to 7% or more for an airlaid nonwoven fabric having a recess formed on one surface. Thereby, in the state which is not impregnated with lotion, a decorative design is displayed by the recessed part formed in one surface of the air-laid nonwoven fabric sheet. On the other hand, when the lotion is impregnated, the concave portion becomes small, and a desired water separation is ensured. The upper limit value of the recovery rate after weighting when wet is set to a value that can be suitably used as a cosmetic puff. The recovery rate after weighting when wet is set by the material of the air laid nonwoven sheet constituting the cosmetic puff, the method of forming the recesses, and the like.
In addition, it is preferable that the fiber weight per unit length of the pulp fiber contained in the air laid nonwoven fabric sheet is 0.20 mg / m or more. In this case, the average pore size (the diameter of the void portion) is 100 μm or more, and a strong skeleton structure can be obtained. The recovery rate after wet weighting, the collective water separation rate, and the divided water separation rate can be increased.

In another form of the first invention, the air-laid nonwoven sheet includes hydrophobic synthetic fibers having hydrophobicity. As the “hydrophobic synthetic fiber”, typically, one or more of polyethylene terephthalate fiber (PET), polyethylene fiber (PP), and nylon fiber can be used. By using an airlaid nonwoven fabric sheet containing hydrophobic synthetic fibers having hydrophobicity, desired water separation can be more easily ensured.
In addition, it is preferable to use the airlaid nonwoven fabric sheet which contains a hydrophobic synthetic fiber in the ratio of 10 to 50 weight%. Thereby, the recovery rate after weighting of the air-laid nonwoven fabric sheet, the collective water separation rate, and the divided water separation rate can be increased.

  In still another form of the first invention. The air laid nonwoven fabric sheet has an outer layer portion made of rayon fibers. The outer layer part which consists of rayon fibers should just be provided in at least one of the outer layer parts. Thereby, the touch becomes smooth.

The cosmetic puff of the second invention is constituted by one air laid nonwoven fabric sheet produced by a known air laid method. The airlaid nonwoven sheet preferably includes pulp fibers or pulp fibers and hydrophobic synthetic fibers.
One air laid nonwoven fabric sheet has a first air laid nonwoven fabric sheet on one side and a second air laid nonwoven fabric sheet on the other side with a folding line interposed therebetween. And this 1 airlaid nonwoven fabric sheet is folded along the folding line, and the 1st airlaid nonwoven fabric sheet and the 2nd airlaid nonwoven fabric sheet are piled up. In addition, in one of the first airlaid nonwoven fabric sheet and the second airlaid nonwoven fabric sheet, a plurality of recesses are formed on the surface opposite to the surface facing the other. The recess may be formed on the entire surface, or may be formed in a partial region of the surface. By appropriately setting the shape, size, arrangement position, and the like of the recess, the decorative design can be displayed on the surface on which the recess is formed. Thereby, the appearance of a cosmetic puff, a high-class feeling, etc. can be improved.
In this invention, it can be used in the state with which the 1st air laid nonwoven fabric sheet and the 2nd air laid nonwoven fabric sheet were piled up. For this reason, among the opposing surfaces of the other air-laid nonwoven sheet (first air-laid nonwoven sheet or second air-laid nonwoven sheet) in which no recess is formed, one air-laid nonwoven sheet (second air-laid nonwoven sheet or second air-laid nonwoven sheet or first Putting etc. can be performed using the surface on the opposite side to the surface opposite to the airlaid nonwoven fabric sheet of 1). In this case, since the other air-laid nonwoven sheet is impregnated with lotion, the concave portion formed in one air-laid nonwoven sheet has little influence on the water separation of the cosmetic puff. As the first and second airlaid nonwoven fabric sheets, it is preferable to use airlaid nonwoven fabric sheets having a desired post-wet weight recovery rate, collective water separation rate, and divided water separation rate.

In another form of the second invention, one air-laid nonwoven sheet has a plurality of holes formed along the folding line. The hole is typically formed by perforation. In this embodiment, the first air-laid nonwoven fabric sheet and the second air-laid nonwoven fabric sheet can be separated along the folding line in which the holes are formed. The shape, spacing, and the like of the holes are selected so that the first air-laid nonwoven sheet and the second air-laid nonwoven sheet can be easily separated along the fold line when necessary.
In this embodiment, the first air-laid nonwoven sheet and the second air-laid nonwoven sheet are used in a stacked form, and the first air-laid nonwoven sheet and the second air-laid nonwoven sheet are used in a use form separated along a fold line. Can do.

In still another embodiment of the second invention, the first air-laid nonwoven fabric sheet and the second air-laid nonwoven fabric sheet are joined at a location away from the folding line by a set distance or more. As the “set distance”, typically, a finger insertion space in which the index finger or the index finger and the middle finger can be inserted is formed between the first air laid nonwoven sheet and the second air laid nonwoven sheet by the fold line and the joint portion. Distance to be selected. The joining portion only needs to be separated from the folding line by a set distance or more, and the joining location, joining shape, and the like can be appropriately selected. The joint is typically formed in parallel (including substantially parallel) to the fold line. In addition, the first air-laid nonwoven fabric sheet and the second air-laid nonwoven fabric sheet may be firmly joined or may be joined in a peelable manner. Moreover, a junction part may be formed continuously and may be formed in the location away from each other.
In this embodiment, since it can be used with a finger inserted into the finger insertion space, handling becomes easy and putting can be performed in a short time. In particular, in the present invention, both ends of the finger insertion space are open. Thereby, since a finger can be easily inserted into the finger insertion space, handling becomes easier.

In still another embodiment of the second invention, the first air-laid nonwoven fabric sheet and the second air-laid nonwoven fabric sheet are joined so as to be able to be peeled off at a position away from the folding line by a set distance or more. Various methods can be used as a method of bonding to the bond in a peelable manner, and a hot embossing method is preferably used. When the first airlaid nonwoven fabric sheet and the second airlaid nonwoven fabric sheet are joined in a peelable manner using a hot embossing method, the embossed part is joined. A decrease in bonding force due to penetration of water or the like can be suppressed. Thereby, it can prevent that a junction part peels. When the hot embossing method is used, the embossed shape is appropriately selected according to the bonding force, the visual effect, and the like.
In this embodiment, a finger insertion space is formed between the first air laid nonwoven sheet and the second air laid nonwoven sheet, and the first air laid is separated along the folding line or peeled off at the joint portion. Use in which the nonwoven fabric sheet and the second air laid nonwoven fabric sheet are spread, separated along the folding line and peeled off at the joint to separate the first air laid nonwoven fabric sheet and the second air laid nonwoven fabric sheet. can do.

3rd invention is comprised by the 1st airlaid nonwoven fabric sheet and the 2nd airlaid nonwoven fabric sheet which are manufactured by the well-known airlaid method. The first and second airlaid nonwoven sheets preferably include pulp fibers or pulp fibers and hydrophobic synthetic fibers.
The 1st air laid nonwoven fabric sheet and the 2nd air laid nonwoven fabric sheet are joined in the 1st joined location along one direction in the state where it piled up. The phrase “along the direction” typically means “parallel to (including substantially parallel to) the direction”. One of the first air-laid nonwoven fabric sheet and the second air-laid nonwoven fabric sheet has a plurality of recesses formed on the surface opposite to the surface facing the other. The recess may be formed on the entire surface, or may be formed in a partial region of the surface. By appropriately setting the shape, size, arrangement position, and the like of the recess, the decorative design can be displayed on the surface on which the recess is formed. Thereby, the appearance of a cosmetic puff, a high-class feeling, etc. can be improved.
In this invention, it can be used in the state with which the 1st air laid nonwoven fabric sheet and the 2nd air laid nonwoven fabric sheet were piled up. For this reason, among the opposing surfaces of the other air-laid nonwoven sheet (first air-laid nonwoven sheet or second air-laid nonwoven sheet) in which no recess is formed, one air-laid nonwoven sheet (second air-laid nonwoven sheet or second air-laid nonwoven sheet or first Putting etc. can be performed using the surface on the opposite side to the surface opposite to the airlaid nonwoven fabric sheet of 1). In this case, since the other air-laid nonwoven sheet is impregnated with lotion, the concave portion formed in one air-laid nonwoven sheet has little influence on the water separation of the cosmetic puff. As the first and second airlaid nonwoven fabric sheets, it is preferable to use airlaid nonwoven fabric sheets having a desired post-wet weight recovery rate, collective water separation rate, and divided water separation rate.

In another form of the third invention, the first air-laid nonwoven sheet and the second air-laid nonwoven sheet are joined in a peelable manner at the first joining location. Although various methods can be used as a method for bonding in a peelable manner, a hot embossing method is preferably used.
In this embodiment, the first air-laid nonwoven fabric sheet and the second air-laid nonwoven fabric sheet are used in an overlapping manner, and the first air-laid nonwoven fabric sheet and the second air-laid nonwoven fabric sheet are separated from each other at the joint portion. Can be used.

In still another embodiment of the third invention, the first air-laid nonwoven fabric sheet and the second air-laid nonwoven fabric sheet are further separated from the first joint location by a set distance or more in a direction intersecting in one direction. It is joined so that it can be peeled off at the joint. As the “set distance”, typically, a finger can be inserted between the first air-laid nonwoven fabric sheet and the second air-laid nonwoven fabric sheet by the first and second joints. The distance at which the space is formed is selected. The joining portion only needs to be separated from the folding line by a set distance or more, and the joining location, joining shape, and the like can be appropriately selected. The joint is typically formed in parallel (including substantially parallel) in one direction.
In this embodiment, the first insertion is performed at a location where the finger insertion space is formed between the first air-laid nonwoven sheet and the second air-laid nonwoven sheet, and the first and second joint portions are separated. Use in an expanded usage form of the airlaid nonwoven sheet and the second airlaid nonwoven sheet, and in a usage form in which the first airlaid nonwoven sheet and the second airlaid nonwoven sheet are separated by peeling at the first and second joints. can do.

The water separation of the sheet in the state where the skin lotion is impregnated can be evaluated using a wet weighted recovery rate indicating the degree of recovery of the wet sheet thickness. The recovery rate after weighting when wet is a thickness when a predetermined amount of test liquid is impregnated into a sheet evaluation piece of a predetermined size, and a predetermined force (also referred to as “load”) is applied to the sheet evaluation piece, It is calculated by the thickness when the application of the predetermined force is released.
In still another embodiment of the second and third inventions, the recovery rate after weighting of the first and second airlaid nonwoven sheets is set to 7% or more.
In addition, as the 1st and 2nd airlaid nonwoven fabric sheet | seat, the airlaid which contains at least one of the pulp fiber whose fiber weight per unit length is 0.20 g / m or more, or the hydrophobic synthetic fiber of the ratio of 10 to 50 weight% It is preferable to use a nonwoven sheet. In addition, the first roll that has a flat outer peripheral surface and generates heat, and the second roll that has a plurality of protrusions formed on the outer peripheral side, are recessed on one surface of one airlaid nonwoven fabric sheet. Is preferably formed.
By using the first and second airlaid nonwoven fabric sheets having a recovery rate after weighting when wet of 7% or more, the first and second makeup puffs make up the makeup puff while giving the makeup puff appearance and luxury. It is possible to ensure the desired water separation of each airlaid nonwoven sheet when wet.

The 4th invention is a crevice formation method which forms a plurality of crevice in one side of the surfaces which a nonwoven fabric sheet counters.
The present invention includes a first roll that has a flat outer peripheral surface, generates heat, and a second roll that has a plurality of protrusions formed on the outer peripheral side. The first roll and the second roll are arranged so that the shortest distance between the outer peripheral surface of the first roll and the protrusion of the second roll is shorter than the thickness of the nonwoven fabric sheet. Typically, it arrange | positions so that the axial direction of a 1st roll and the axial direction of a 2nd roll may become parallel (a substantially parallel is included). And the 1st roll and the 2nd roll are rotated in the state which made the other surface of the opposing surfaces of a nonwoven fabric sheet contact over the setting field of the peripheral surface of the 1st roll, A plurality of recesses are formed on one surface. The setting region includes a contact region where one surface of the nonwoven fabric sheet contacts the protrusion of the second roll, a front region along one direction of the rotation direction of the first roll with respect to the contact region, A rear region is included along the other direction of the rotation direction of the first roll with respect to the contact region. As a result, the nonwoven fabric sheet is heated (remaining heat) by the first roll in the front region, and then heated by the first roll in the contact region, while the outer circumferential surface of the first roll and the second roll. A recess is formed on one surface by the protrusion, and then heated by the first roll in the rear region. Therefore, a recess can be formed on one surface of the nonwoven fabric sheet without destroying the skeleton structure. In addition, when forming a recessed part in the one part area | region of the nonwoven fabric sheet, the control apparatus which controls contact | abutting and non-contacting of the protrusion of a 2nd roll with respect to one surface of a nonwoven fabric sheet is provided. It is done. For example, a control device that controls the position of the second roll is provided.
By using the recess forming method of the present invention, it is possible to produce a nonwoven fabric sheet in which a plurality of recesses are formed on one surface and the recovery rate after weighting when wet is 7% or more.
As the nonwoven fabric sheet, it is preferable to use an airlaid nonwoven fabric sheet containing at least one of pulp fibers having a fiber weight per unit length of 0.20 g / m or more or hydrophobic synthetic fibers in a proportion of 10 to 50% by weight.

  In another form of the fourth invention, the setting area is set as an area of a half or more along the rotation direction of the first roll, and the contact area is along the rotation direction of the first roll of the setting area. Located in the center. In this embodiment, the nonwoven fabric sheet can be sufficiently heated before and after the projection of the second roll is brought into contact with one surface of the nonwoven fabric sheet. Therefore, an air-laid nonwoven fabric sheet having a plurality of recesses formed on one surface and having a recovery rate after weighting when wet of 7% or more can be obtained more easily.

  By using the present invention, it is possible to obtain a cosmetic puff having a plurality of recesses on the surface while ensuring desired water separation when impregnated with lotion or the like.

Embodiments of the present invention will be described below with reference to the drawings.

A recess or protrusion for displaying a decorative pattern on the surface of a sheet is generally called “emboss”.
The air laid nonwoven fabric sheet 10 used in the present embodiment is manufactured by a known air laid method. As shown in FIG. 3, the air-laid nonwoven fabric sheet 10 includes an inner layer portion 11 and outer layer portions 12 </ b> A and 12 </ b> B provided on both surfaces of the inner layer portion 11. The outer layer portions 12A and 12B are typically composed of at least one fiber of rayon, cotton, silk, pulp, and the like. The inner layer portion 11 is typically composed of pulp fibers and polyethylene terephthalate fibers. Note that the inner layer portion 11 does not include polyethylene terephthalate fiber, and may be configured by pulp fiber. Further, the outer layer portions 12A and 12B can be made of the same fibers as the inner layer portion 11. Polyethylene terephthalate corresponds to the “hydrophobic synthetic fiber” of the present invention.

As shown in FIG. 1, the recess forming apparatus 100 according to the present embodiment includes a first roll 110 and a second roll 120. As the first roll 110, a roll having a flat outer peripheral surface 110A is used. Further, as the first roll 110, a heating roll capable of generating heat is used. For example, a roll having a heating device is used. As the second roll 120, a roll having a plurality of processing protrusions 121 and processing recesses 122 formed on the outer peripheral side is used. For example, a roll having a plurality of processing recesses 122 formed on the outer peripheral surface 120A is used. In this case, the outer peripheral surface 120 </ b> A is the tip of the processing projection 121. In FIG. 1 and FIG. 2, the processing protrusion 121 and the processing recess 122 are formed in the entire area on the outer peripheral side of the second roll 120, but may be formed in part. The locations of the processing projections 121 and the processing recesses 122 are appropriately set according to the desired decorative design. The outer peripheral surface 110A of the first roll 110 and the outer peripheral surface 120A of the second roll 120 (virtual outer peripheral surface including the tip of the processing projection 121) are viewed from a direction intersecting (orthogonal to) the axial direction. It has a circular shape. Further, the first roll 110 and the second roll 120 are driven by a drive device (not shown) such as an electric motor.
The first roll 110 and the second roll 120 are arranged so that the axial direction of the first roll 110 and the axial direction of the second roll 120 are parallel (including substantially parallel). Further, the first roll 110 and the second roll 120 are composed of the outer peripheral surface 110A of the first roll 110 and the tip of the processing protrusion 121 of the second roll 120 (in FIG. It arrange | positions so that the minimum space | interval with the outer peripheral surface 120A may become below the thickness of the air-laid nonwoven fabric sheet 10. FIG. That is, when the air-laid nonwoven fabric sheet 10 passes between the first roll 110 and the second roll 120, the air-laid nonwoven fabric sheet 10 has an outer peripheral surface 110A of the first roll 110 and a processing protrusion of the second roll 120. The first roll 1110 and the second roll 120 are disposed so as to be pressed by the front end portion of 121.

In addition, the air-laid nonwoven fabric sheet 10 has a surface 10B (the other of the opposing surfaces) on the outer peripheral surface 110A of the first roll 110 and a set region 111 along the circumferential direction (rotation direction) of the outer peripheral surface 110A. It arrange | positions so that it may contact over. For example, guide rolls 131 and 132 for guiding the movement of the air laid nonwoven fabric sheet 10 are provided. Here, in the setting region 111 where the surface 10B of the air laid nonwoven fabric sheet 10 and the outer peripheral surface 110A of the first roll 110 are in contact, the surface 10A of the air laid nonwoven fabric sheet 10 (one of the opposing surfaces) is the second. A contact region 111b that contacts the tip of the processing protrusion 121 of the roll 120, and a front region 111a on one side along the circumferential direction of the outer peripheral surface 110A of the first roll 110 with respect to the contact region 111b. And a rear region 111c on the other direction side. In the present embodiment, the setting area 111 is set to an area of at least a half circumference of the outer peripheral surface 110 </ b> A of the first roll 110. And the contact area | region 111b is arrange | positioned in the center location (a substantially central location is included) along the circumferential direction of 110 A of outer peripheral surfaces of the 1st roll 1110 of the setting area | region 111. FIG. In addition, the range of the setting area 111, the front area 111a, the contact area 111b, and the rear area 111c, the arrangement position of the front area 111a, the contact area 111b, and the rear area 111c in the setting area 111 are the surfaces of the airlaid nonwoven fabric sheet 10. It can be set as appropriate according to the decorative design displayed on 10A, the material and thickness of the air-laid nonwoven fabric sheet 10, and the like.
Then, in a state where the surface 10B of the air laid nonwoven fabric sheet 10 is in contact with the setting region 111 of the outer peripheral surface 110A of the first roll 110, the first roll 110 and the second roll 120 are opposite to each other (for example, FIG. 2 in the direction indicated by the arrow). At this time, the air-laid nonwoven fabric sheet 10 is first heated (preheated) by the first roll 110 in the front region 111a. Thereafter, in the contact region 111b, the outer peripheral surface 110A of the first roll 110 and the tip of the processing protrusion 121 of the second roll 120 are pressed to form a recess while being heated. Thereafter, in the rear region 111c, the first roll 110 is heated.
In addition, when forming a recessed part intermittently in the surface 10B of the air laid nonwoven fabric sheet 10, contact | abutting and non-contact | abutting of the front-end | tip part of the process protrusion 121 of the 2nd roll 120 with respect to the surface 10A of the air laid nonwoven fabric sheet 10 A control device is provided for controlling the above. For example, when forming a recess in the surface 10A of the air laid nonwoven fabric sheet 10, the second roll 120 is moved to the contact position, and when the recess is not formed, the second roll 120 is moved to the standby position. A control device is provided.

FIG. 4 and FIG. 5 show a cosmetic puff 200 constituted by an airlaid nonwoven fabric sheet 10 in which a concave portion is formed on one surface 10A by the concave portion forming apparatus 100 of the present embodiment. The cosmetic puff 200 shown in FIG. 4 and FIG. 5 uses the air-laid nonwoven fabric sheet 10 having a recess formed on one surface 10A as it is as a cosmetic puff. 4 is a plan view of the cosmetic puff 200, and FIG. 5 is a cross-sectional view taken along the line VV of FIG.
The cosmetic puff 200 (specifically, the airlaid nonwoven fabric sheet 10 with recesses formed therein) has a plurality of recesses 250 formed on one surface 200A. Thereby, the decorative design 260 is displayed on the one surface 200 </ b> A side of the nonwoven fabric sheet 200 by the plurality of recesses 250.

  In the conventional apparatus shown in FIG. 14, the cotton 550 is only in the contact area where the concave mold 511 (or flat outer peripheral surface) of the first roll 510 and the protruding mold 521 of the second roll 520 are in contact with the cotton material 550. The material 550 is heated by the second roll 520. For this reason, the cotton material 550 is cooled immediately after the recess 551 is formed, and the recess 551 is restored. Therefore, in the conventional apparatus, it is necessary to strongly press the protruding mold 521 of the second roll 520 against the cotton material 550 so that the skeleton structure of the cotton material 550 is destroyed and the recess 572A is not restored. In this case, the skeleton structure of the cotton material 550 is destroyed, so that the recovery rate after weighting when wet (details will be described later) is deteriorated, and a desired water separation cannot be obtained in a state where the lotion is impregnated. In particular, the amount of water separation during the first putting after impregnating the skin lotion is large.

In the present embodiment, a roll (heating roll) that has a flat outer peripheral surface 110 </ b> A and can generate heat is used as the first roll 110. Further, the air laid nonwoven fabric sheet 10 is brought into contact with the outer peripheral surface 110 </ b> A of the first roll 110 in the front region and the rear region before and after the contact region where the processing protrusion 121 of the second roll 120 contacts the air laid nonwoven fabric sheet 10. I am letting. That is, after the air laid nonwoven fabric 10 is heated (preheated) in the front region 110a, a concave portion 250 is formed on one surface 10A of the air laid nonwoven fabric 10 in the contact region 111b, and after the concave portion 250 is formed, further air laid in the rear region 111c. The nonwoven fabric sheet 10 is heated. Thereby, the recessed part 250 can be formed in one surface 10A of the air laid nonwoven fabric sheet 10 without destroying the skeleton structure of the air laid nonwoven fabric sheet 10. Therefore, the recovery rate after weighting of the airlaid nonwoven fabric sheet 10 in which the recesses 250 are formed becomes high, and a desired water separation can be obtained in a state in which the skin lotion is impregnated. Moreover, the air-laid nonwoven fabric sheet 10 containing a lot of pulp is used, and the concave portion 250 can be easily formed by this.
FIG. 6 shows a state in which a cosmetic puff 200 composed of an airlaid nonwoven fabric sheet 10 having a concave portion 250 formed on one surface 10A is impregnated with lotion using the concave portion forming apparatus 100 of the present embodiment. Since the skeleton structure of the airlaid nonwoven fabric sheet 10 constituting the cosmetic puff 200 of the present embodiment is not destroyed, the impregnated lotion 50 makes the recess 250 smaller as shown in FIG. 6 (typically Specifically, the depth of the concave portion 250 becomes shallow, and it becomes difficult to distinguish the decorative pattern constituted by the concave portion 250). Therefore, deterioration of water separation due to the recess 250 can be prevented.

  In addition, when the recessed part 250 is formed in the surface 10A of the air laid nonwoven fabric sheet 10 by the outer peripheral surface 110A of the first roll 110 and the processing protrusion 121 of the second roll 120, the air laid nonwoven fabric sheet 10 is preheated. There is a need. In the present embodiment, as the first roll 110, a roll (heating roll) that has a flat outer peripheral surface 110A and can generate heat is used, and the processing protrusion of the second roll 120 is used. The air laid nonwoven fabric sheet 10 is brought into contact with the outer peripheral surface 110 </ b> A of the first roll 110 over the front region 111 a and the rear region 111 c before and after the contact region 111 b where 121 contacts the air laid nonwoven fabric sheet 10. That is, the air laid nonwoven fabric sheet 10 is heated by the first roll 110 before the processing protrusion 121 of the second roll 120 abuts on the surface 10A of the air laid nonwoven fabric sheet 10 to form the recess 250. For this reason, in this Embodiment, the heating before forming the recessed part 250 in the airlaid nonwoven fabric sheet 10 and the heating after forming the recessed part 250 can be performed with the 1st roll 110, and the structure of the recessed part formation apparatus 100 is possible. Can be simplified.

In the recess forming apparatus 100 shown in FIGS. 1 and 2, heating (preheating) before forming the recess is performed by bringing the air-laid nonwoven fabric sheet 10 into contact with the setting region 111 of the outer peripheral surface 110 </ b> A of the first roll 110. However, in order to perform the formation process of the recess 250 at a high speed, it is necessary to sufficiently perform heating (preheating) before forming the recess. In such a case, a heating device for further heating the air-laid nonwoven fabric sheet 10 is provided before forming the recesses 250.
For example, as in the recess forming apparatus 100 of the second embodiment shown in FIG. 7, the hot air supply apparatus is located upstream from the first roll 110 (the side on which the airlaid nonwoven fabric sheet 10 is sent). 140 is provided. The hot air supply device 140 heats (preheats) the airlaid nonwoven fabric sheet 10 by supplying hot air to the airlaid nonwoven fabric sheet 10.
Or the heating rolls 151 and 152 are provided in the upstream from the 1st roll 110 like the recessed part formation apparatus 100 of 3rd Embodiment shown by FIG. The heating rolls 151 and 152 heat (preheat) the air-laid nonwoven fabric sheet 10 when the air-laid nonwoven fabric sheet 10 is sent in a state in contact with the outer peripheral surface.

The cosmetic puff 200 of the first embodiment uses the air-laid nonwoven fabric sheet 10 having the concave portion 250 formed on one surface 10A as it is, but the shape and configuration of the cosmetic puff can be appropriately set.
A cosmetic puff 300 according to a second embodiment is shown in FIGS. The cosmetic puff 300 according to the second embodiment is constituted by a first airlaid nonwoven fabric sheet and a second airlaid nonwoven fabric sheet that are overlapped by folding one airlaid nonwoven fabric sheet. FIG. 9 shows a state in which the air-laid nonwoven fabric sheet constituting the cosmetic puff 300 of the present embodiment is opened, and FIG. 10 shows a state in which the air-laid nonwoven fabric sheet is folded along the folding line 300h. Hereinafter, the air laid nonwoven fabric constituting the cosmetic sheet 300 is referred to as “air laid nonwoven fabric sheet 300”.
As shown in FIG. 9, one air-laid nonwoven sheet 300 constituting the cosmetic puff 300 of the present embodiment includes edge portions 300 a and 300 c having a length M1 and edges 300 b and 300 d having a length L1. It has a square shape. The airlaid nonwoven fabric sheet 300 has a first airlaid nonwoven fabric sheet 310 on one side of the fold line 300h and a second airlaid nonwoven fabric sheet 320 on the other side. The first airlaid nonwoven fabric sheet 310 is formed in a square shape having edge portions 30a and 300h having a length M1 and edge portions 300b1 and 300d2 having a length L2. The second air laid nonwoven fabric sheet 320 is formed in a square shape having edge portions 300c and 300h having a length M1 and edge portions 300b2 and 300d1 having a length L3 (L3> L2). A plurality of holes 300H are formed along the folding line 300h. The hole 300h is typically formed by perforation. The shape, size, arrangement position, and the like of the hole 300H are set so that the first air-laid nonwoven sheet 310 and the second air-laid nonwoven sheet 320 can be separated along the fold line 300h when necessary. The first air-laid nonwoven sheet 310 has a plurality of recesses 350 formed on one surface 300A by the recess forming apparatus 100 described above. By this recess 350, the decorative design 360 is displayed on the one surface 300A side.

Next, as shown in FIG. 10, one air-laid nonwoven sheet 300 is folded along a folding line 300 h, and the first air-laid nonwoven sheet 310 and the second air-laid nonwoven sheet 320 are overlapped. At this time, the concave portion 350 formed on one surface 300A of the first air-laid nonwoven sheet 310 is disposed on the outside, that is, one surface 300A is disposed on the outside and the other surface 300B is disposed on the inside. Wrap to be placed. This configuration is a configuration according to the present invention “one of the first airlaid nonwoven fabric sheet and the second airlaid nonwoven fabric sheet has a plurality of recesses formed on the surface opposite to the surface facing the other”. Corresponding to
Here, the length L2 of the edge portions 300b1 and 300d2 of the first air laid nonwoven fabric sheet 310 is set shorter than the length L3 of the edge portions 300b2 and 300d1 of the second air laid nonwoven fabric sheet 320 (L3> L2). . For this reason, when one airlaid nonwoven fabric sheet 300 is folded along the folding line 300h and the first airlaid nonwoven fabric sheet 310 and the second airlaid nonwoven fabric sheet 320 are overlapped, the edge 300a of the first airlaid nonwoven fabric sheet 310 is The second airlaid nonwoven fabric sheet 320 is arranged at a position separated by a distance n1 (= L3-L2) on the folding line 20h side from the edge portion 300c. The value of the distance n1 is set as appropriate.
In addition, the edge part 300a of the 1st airlaid nonwoven fabric sheet 310 is "the edge part of the 1st airlaid nonwoven fabric sheet facing the folding line", and the edge part 300c of the 2nd airlaid nonwoven fabric sheet 320 is “The edge of the second air-laid nonwoven sheet on the side facing the fold line”. In addition, the edge portions 300b1 and 300d2 of the first air laid nonwoven fabric sheet 310 are “edge portions of the first air laid nonwoven fabric sheet that extend in the direction intersecting the fold line from both ends of the fold line”. The edge portions 300b2 and 300d1 of the second air-laid nonwoven fabric 320 are “edge portions of the second air-laid nonwoven fabric sheet that extend in the direction intersecting with the folding line from both ends of the folding line”.

The first air-laid nonwoven fabric sheet 310 and the second air-laid nonwoven fabric sheet 320 are joined in a peelable manner at a place away from the fold line 300h by a set distance L4. At this time, the joining portion 370 is joined so as to be formed at a location away from the edge portion 300a of the first air-laid nonwoven fabric sheet 310 and the edge portion 300c of the second air-laid nonwoven fabric sheet 320. In the present embodiment, since [L3> L2], the joining portion 370 is formed at a location separated from the edge portion 300a of the first air-laid nonwoven fabric 310 by a distance n2 in the direction of the folding line 300h. Thereby, since the edge 300a of the 1st airlaid nonwoven fabric sheet part 310 and the edge 300c of the 2nd airlaid nonwoven fabric sheet 320 and the part between the junction parts 370 are not joined, the 1st airlaid nonwoven fabric sheet 310 of FIG. The part on the edge part 300a side and the part on the edge part 300c side of the second air-laid nonwoven fabric 320 can be easily grasped with a finger. Therefore, the first air-laid nonwoven sheet 310 and the second air-laid nonwoven sheet 320 and the edge 300c-side part of the second air-laid nonwoven sheet 310 can be easily pulled in the direction of separating, The second air laid nonwoven fabric 320 can be easily peeled off at the joint portion 370. Note that the values of n1 and n2 can be set as appropriate.
As a method of joining the first airlaid nonwoven fabric sheet 310 and the second airlaid nonwoven fabric sheet 320 so as to be peelable, various joining methods can be used. 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. In this case, the first airlaid nonwoven fabric sheet 310 and the second airlaid nonwoven fabric sheet 320 are thermocompression bonded at the uneven embossed portion. When joining by hot embossing, since it becomes difficult for skin lotion etc. to penetrate into the joint portion, it is possible to suppress a decrease in the joint strength of the joint portion.

In this case, the fold line 300h and the joint portion 370 fold back a finger insertion space between the first air-laid nonwoven fabric sheet 310 and the second air-laid nonwoven fabric sheet 320 so that both ends are open and at least one finger can be inserted. Joined to form along line 300h. Here, the interval between the finger insertion spaces is determined by a line 380 that is parallel to the folding line 300h and passes through the joint portion 370 and is closest to the folding line 300h. In the present specification, a line that is parallel to (including substantially parallel to) the center line of the finger insertion space and that passes through the joint portion is closest to the center line of the finger insertion space is referred to as a “joint line”. In the present embodiment, the line 380 shown in FIG. 10 corresponds to the “joining line”. In the present embodiment, the center line of the finger insertion space is parallel (including substantially parallel) to the direction in which the folding line 300h extends. In the present embodiment, joint portion 370 is formed such that distance L4 between joint line 380 and fold line 300 is equal to or greater than a set distance. As the set distance, for example, a distance that forms an insertion space into which the index finger or the index finger and the middle finger can be inserted is used.
In the present embodiment, the direction of the finger insertion space (the direction of the center line of the finger insertion space), that is, the direction of the fold line 300h (the direction in which the fold line 300h extends) corresponds to “one direction” of the present invention. To do. The direction intersecting (orthogonal) with the direction of the finger insertion space, that is, the direction intersecting (orthogonal) with the direction of the folding line 300h corresponds to the “direction intersecting with one direction” of the present invention. The direction of the return line 300h is, for example, the direction of a line connecting both ends of the return line 300h.
Moreover, the 1st airlaid nonwoven fabric sheet 310 and the 2nd airlaid nonwoven fabric sheet 320 are joined so that peeling is possible in the location which is mutually separated along the direction of the folding line 300h. That is, the joint portion 370 is formed at a location separated from each other along the direction of the folding line 300h. In the present specification, the description “along the direction” typically means “parallel to the direction (including substantially parallel)”. Thereby, even if the joint part on the end side (edge part 300b1, 300b2 side or edge part 300d1, 300d2 side) is peeled off, it is possible to prevent the joint part adjacent to the joint part on the end side from peeling off in conjunction. it can.

The recovery rate after wet weighting and the split 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 / cm ² )) and the second pressure (3.92 kPa (40 gf / cm ² )) were applied by a presser foot (1 cm ² (φ11.28 mm)) Was measured. 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 / cm ² ] 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. And the water separation rate (%) of the 1st time was computed using a formula [(Wf-We) / Wdx100].
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].

The recovery rate after weighting in Example 1 and Example 2 is 7% or more as in Comparative Example 1 and Comparative Example 2 in which no recess is formed. On the other hand, the recovery rates after weighting in Comparative Example 3 and Comparative Example 4 are both less than 7%. Thereby, Example 1 and Example 2 have substantially the same recovery performance after weighting as in Comparative Examples 1 and 2 in which no recess is formed, and when wet compared to Comparative Example 3 and Comparative Example 4. It was confirmed that the recovery performance after weighting was excellent. Therefore, 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 split water separation rate)
The water separation rate of Example 1 and Example 2 (first time + second time) was 85% or more in the same manner as in Comparative Example 1 and Comparative Example 2, and (First Time + Second Time) of Example 1 and Example 2 + 3rd time) The water separation rate is 90% or more in the same manner as in Comparative Example 1 and Comparative Example 2. Further, the water separation rates of Comparative Example 3 and Comparative Example 4 (first time + second time) are both 85% or more, and the water separation rates of Comparative Example 3 and Comparative Example 4 (first time + second time + third time) are both 90% or more.
However, the first-time water separation rate of Example 1 and Example 2 is less than 70% as in Comparative Example 1 and Comparative Example 2 in which no recess is formed, whereas Comparative Example 3 and Comparative Example 4 The first water separation rate is 80% or more. Thereby, it was confirmed that Example 1 and Example 2 were excellent in the first-time water separation rate compared with Comparative Example 3 and Comparative Example 4. That is, it is confirmed that Example 1 and Example 2 are superior in split water separation performance to Comparative Example 3 and Comparative Example 4 as in Comparative Example 1 and Comparative Example 2 in which no recess is formed. It was. Thereby, 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 performing the putting in a plurality of times and applying the lotion.
As described above, when the recovery rate after weighting when wet is 7% or more, the diameter (pore size) between the fibers constituting the air laid nonwoven fabric hardly changes even after wet weighting. As a result, the first water separation rate can be set to 80% or less.

By the way, when a cosmetic puff is constituted by an air laid nonwoven fabric having a recess formed on one surface, the makeup method in which the recess forming method and the structure (material and blending ratio) of the air laid nonwoven sheet are impregnated with skin lotion, etc. Affects water release of puffs. For Examples 3 to 9 and Comparative Examples 5 and 6 of the present invention, the recovery rate after weighting when wet, the collective water separation rate and the divided water separation rate were measured. The measurement results are shown in FIG.
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.

To do. 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 the top of 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].

From the measurement results of Examples 3 to 9 and Comparative Examples 5 and 64 shown in FIG.
(Evaluation result of recovery rate after weighting when wet)
Each of the test pieces of Examples 3 to 9 has a wet weighted recovery rate of 7% or more, and each of the comparative examples 5 and 6 has a wet weighted recovery rate of less than 7%. In other words, it was confirmed that Examples 3 to 9 were superior in recovery performance after weighting when wet compared to Comparative Examples 5 and 6. 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 3 to 9 are both 75% or more, and the collective water separation rates of Comparative Examples 5 and 6 are both less than 75%. That is, it was confirmed that Examples 3-9 were superior in collective water separation performance compared to Comparative Examples 5 and 6. 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 3 to 9, 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. Moreover, the comparative examples 5 and 6 have a water separation rate of less than 85% (first time + second time) and a water separation rate of less than 90% (first time + second time + third time). That is, it was confirmed that Examples 3 to 9 were superior in water separation performance in the division compared to Comparative Examples 5 and 6. 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 3 to 9, the lotion according to the putting power The release amount can be optimized.
Specifically, the air laid nonwoven fabric sheets corresponding to Examples 3 to 9 all include 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 airlaid nonwoven fabric sheets corresponding to Examples 4 to 8 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.
Airlaid nonwoven fabric sheets corresponding to Examples 3 to 9 have outer layer portions 12A and 12B 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 part 12A, 12B 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 (PET), polypropylene fibers (PP), polyethylene fibers (PE), and nylon fibers can be used.
While forming a concave portion on one surface of an airlaid nonwoven fabric sheet having at least one of such a configuration using the concave portion forming apparatus 100 described above, while ensuring a desired water separation at the time of skin water impregnation, A cosmetic puff having a plurality of recesses formed on the surface can be obtained more easily.

As described above, in the cosmetic puff according to the present embodiment, the recovery rate after wet weighting of the air-laid nonwoven fabric having a plurality of recesses formed on one surface is set to 7% or more. Thereby, when the cosmetic puff is not impregnated with lotion by the airlaid nonwoven fabric sheet having a plurality of recesses formed on one surface, the decorative pattern is displayed by the plurality of recesses formed on one surface. can do. On the other hand, when the cosmetic puff is impregnated with lotion, the concave portion formed on one surface becomes small, so that the water separation (especially, the first water separation) is not deteriorated and used multiple times. can do. Therefore, the decorative design can be displayed by the plurality of concave portions formed on one surface while ensuring the desired water separation during the skin water impregnation.
Further, in the recess forming apparatus or the recess forming method of the present embodiment, a first roll having a flat outer peripheral surface and having a heating function and a second roll having a processing projection on the outer periphery are used. . And the airflaid nonwoven fabric which comprises a makeup | decoration puff is made to contact the outer peripheral surface of a 1st roll over the setting area | region including the front area | region and back area | region arrange | positioned on both sides of a contact area | region. Thereby, a some recessed part can be formed in one surface of an airflaid nonwoven fabric sheet, without destroying skeleton structure. That is, an airlaid nonwoven fabric sheet having a plurality of recesses formed on one surface while ensuring a desired water separation during the impregnation of the skin lotion, and further a cosmetic puff constituted by such an airlaid nonwoven fabric sheet is obtained. Can do. In particular, in the recess forming apparatus or the recess forming method of the present embodiment, the first roller causes the airflaid nonwoven sheet to be overheated (preheated) before the recess is formed and the airflaid nonwoven fabric is heated after the recess is formed. Since this can be done, the configuration can be simplified.

In the case where a cosmetic puff is formed by stacking a first airlaid nonwoven sheet having a recess on one side and a second airlaid nonwoven sheet having no recess on both sides, the second airlaid A non-woven sheet can be impregnated with lotion and then put using the second air-laid non-woven fabric. In this case, it is not necessary to consider the influence on the water separation due to the recess formed in the first air-laid nonwoven fabric sheet. That is, an air laid nonwoven fabric sheet having a desired recovery rate after weighting when wet, a collective water separation rate, and a divided water separation rate can be used in a state where no recess is formed. Even in this case, it is possible to prevent the deterioration of the water separation due to the concave portions formed in the one airlaid nonwoven fabric sheet.
Moreover, although the recessed part was formed in one side (surface on the opposite side to the surface which opposes the other airlaid nonwoven fabric sheet) of one airlaid nonwoven fabric sheet, one surface (one airlaid nonwoven fabric) of the other airlaid nonwoven fabric sheet You may form a recessed part in the surface on the opposite side to the surface which opposes a sheet | seat.
Moreover, each structure demonstrated by embodiment mentioned above can be used individually or in combination with the some structure selected suitably.
