  However, since a conventional face mask is composed of a single sheet body, when it is placed on the entire face of a three-dimensional concavo-convex shape, wrinkles and slack are partially generated, and the face is evenly adhered to the entire face. I can't let you. For this reason, there is a problem that cosmetic liquid or the like cannot be evenly supplied from the face mask to the entire face.

  In addition, there are cuts around the face mask, but not only the troublesome work of picking and sticking each part sandwiched between the cuts around the face mask when using it, but also about the center part of the face Cannot improve the adhesion.

  Furthermore, the lower end of the face mask is only placed from the lower part of the chin to the upper part of the neck, and there is a problem that the face mask is easily peeled off when the face is moved left and right.

  The object of the present invention is to join a sheet body facing the left side surface and the right side surface of the face as a whole at the front end portion facing the median line of the face that is convex outwardly, so that the three-dimensional face An object of the present invention is to provide a method of manufacturing a three-dimensional face mask that can realize a three-dimensional shape along the unevenness with a simple configuration and can be easily brought into close contact with the entire face including the jaw.

  The manufacturing method of the three-dimensional face mask according to the present invention includes a three-dimensional face mask composed of a planar left sheet and a right sheet that are symmetrical to each other, except for tabs that are asymmetrical to each other and extending from the same location in the periphery. A manufacturing method comprising preparing two sheet bodies including an adhesive material on the entire surface in the thickness direction or on the entire surface in at least one surface, and having a shape excluding the base portion of the tab on each of the two sheet bodies A step of forming a cut-out, a step of stacking the two sheet bodies with the one surface facing each other so that the bases match, and a midline of the face The front end portion facing the face and the portion facing the periphery of the face are cut out by a continuous cutting line except for the base portion, and are opposed to the nostril and mouth in the front end portion. The ranges excluding minute; and a molding step of bonding at a predetermined width.

Further, another manufacturing method of a three-dimensional face mask according to the present invention comprises a planar left sheet and a right sheet that are symmetrical to each other except for mutually asymmetrical tabs that extend from the same location around each of them. A method for manufacturing a three-dimensional face mask, two locations facing each other across a central portion in the width direction of a sheet body containing an adhesive material over the entire surface in at least one surface in the thickness direction or at least a part of a predetermined width Forming a cutout having a shape excluding the base portion of the tab, folding the sheet body in half at the center of a part of the predetermined width with the one surface inward, and in the sheet body portion and said base portion front end facing the midline of the face in a state included in at least part of said predetermined width to face around the front end and the face With crop cutting lines contiguous with the exception, including a molding step of bonding the range excluding a portion facing the nostrils and mouth with a predetermined width of the front end.

  It is preferable that the adhesive material has thermoplasticity, and the forming step is a step of heating and bonding a range of the front end portion excluding a portion facing the nostril and mouth with a predetermined width from the front end.

  Moreover, it is preferable that the left side sheet and the right side sheet are made of a nonwoven fabric, and the adhesive material is a powder.

  According to the present invention, the front end portions of the left and right sheets facing the midline of the face are bonded to each other as a convex shape, thereby separating the unbonded portions of the left and right sheets from each other. This makes it possible to create a three-dimensional shape that matches the unevenness of the face. A three-dimensional face mask can be uniformly adhered to the entire face without causing partial wrinkles or slack, and a liquid such as a cosmetic liquid can be uniformly applied to the entire face.

It is a figure which shows another manufacturing process of a solid face mask. It is a top view of the solid face mask which concerns on embodiment of this invention. It is a figure which shows the manufacturing process of the solid fisse mask which concerns on embodiment of this invention.

  As shown in FIG. 1, the three-dimensional face mask 10 includes, for example, a right sheet 1 that faces the left side of the face and a left sheet 2 that faces the left side of the face by punching from a sheet body made of a nonwoven fabric. It is configured to overlap each other with the inner side surfaces in close contact with each other. The right seat 1 and the left seat 2 have a bilaterally symmetric shape. FIG. 1 is a plan view seen from the right seat 1 side, and the left seat 2 is not shown because it is located below the right seat 1.

  The right sheet 1 has a hole 11, a recess 12, and a cut 13. The hole 11 faces the eye. The recess 12 faces the lips. The incision 13 faces the nose. The right seat 1 has a shape in which an upper end 14 protrudes upward and a lower end 15 protrudes downward. The right-side sheet 1 has a thermoplastic adhesive material on the inner surface of the width W portion on the front end 16 side facing the median line of the face rather than the line drawn from the upper end 14 toward the jaw 18 facing the jaw. I have. The adhesive material is, for example, a thermoplastic resin powder. A notch 17 is formed in an intermediate portion of the rear end portion 18 on the opposite side of the front end portion 16 in the peripheral edge portion of the right sheet 1. The left seat 2 is configured in a similar manner with a shape symmetrical to that of the right seat 1.

  The upper and lower ends of the line L drawn from the upper end 14 toward the jaw portion 18 facing the jaw coincide with the upper end 14 and the lower end 15 of the front end portion 16.

  The front end portion 16 of the right seat 1 has a shape that protrudes outward as a whole by a plurality of arcs. As shown by a broken line in FIG. 1, the front end portion 16 is joined to the left-side seat 2 except for a portion facing the nostril and the concave portion 12 with a predetermined width between the upper end 14 and the lower end 15.

  Note that the eyebrow portion 16A facing the eyebrows at the front end portion 16 is formed by an arc that protrudes inward. When the right sheet 1 and the left sheet 2 are opened so as to be separated from each other, the three-dimensional face mask 10 is 3 It exhibits a dimensional curved surface shape. For this reason, the three-dimensional face mask 10 can be reliably adhered to the central portion including the midline of the face.

  Further, since the front end portion 16 of the right seat 1 and the left seat 2 is bonded to the lower end 15 protruding downward, when the three-dimensional face mask 10 is applied to the face, it contacts from the lower surface of the chin to the upper portion of the neck. In this state, the shape of the front end portion 16 is maintained. For this reason, the three-dimensional face mask 10 reliably adheres to the entire face, and the lower part of the three-dimensional face mask 10 can be prevented from being detached from the chin when the head is moved left and right.

  Since the three-dimensional face mask 10 has a three-dimensional curved surface, the three-dimensional face mask 10 can be closely attached to the entire face without forming cuts around the periphery, but in order to further improve the adhesion, the peripheral edges of the right sheet 1 and the left sheet 2 Instead of the notch 17 or together with the notch 17, another notch or the like may be formed in a range excluding the front end portion 16.

  As shown in FIG. 2, when using the three-dimensional face mask 10, the three-dimensional face mask is opened when the ranges excluding the front end portion 16 at the peripheral edge portions of the right sheet 1 and the left sheet 2 are opened in a direction away from each other. 10 forms a three-dimensional shape that is convex outward as a whole.

  For this reason, the three-dimensional face mask 10 adheres uniformly to the entire face of the three-dimensional concavo-convex shape without causing wrinkles or slack. In particular, since the interbrow portion 16A is formed by an arc that is convex inward, the front end portion 16 can be brought into close contact with the midline of the face. As a result, the effect of a liquid such as a beauty essence preliminarily impregnated in the three-dimensional face mask 10 can be uniformly applied to the entire face.

  Further, before use, the three-dimensional face mask 10 is formed into a planar shape by superimposing the right sheet 1 and the left sheet 2 so that the inner side surfaces thereof are in contact with each other. For this reason, it is not bulky when a plurality of three-dimensional face masks 10 themselves are overlaid or when a plurality of packaging bags each containing one-dimensional face masks 10 are overlaid. Handling becomes easy.

  With reference to FIGS. 3A to 3D, an example of a manufacturing process of a three-dimensional face mask will be described below. When manufacturing the three-dimensional face mask 10, first, as shown in FIG. 3A, the sheet 101 that is the material of the three-dimensional face mask 10 is pulled out from the roll, and the surface that is the inner surface of the three-dimensional face mask 10 is pulled out. A thermoplastic adhesive material 102 with a predetermined width S is applied to a central portion in a direction orthogonal to the direction. The predetermined width S when applying the adhesive material is slightly wider than twice the width W shown in FIG.

  Thereafter, the adhesive material 102 may be once melted and fixed to the sheet 101 by heating the sheet 101 for a predetermined time. Thereby, especially when the adhesive material 102 is powder, it is possible to prevent the adhesive material 102 from being detached from the three-dimensional face mask 10 during transportation or use.

  Next, as illustrated in FIG. 3B, the sheet 101 is cut with a predetermined length that is longer than the length in the vertical direction of the three-dimensional face mask 10 in the drawing direction.

  Further, as shown in FIG. 3C, the cut sheet 101 is folded in half along a center line parallel to the drawing direction.

  Finally, as shown in FIG. 3D, the folded sheet 101 is punched into the shape of the right sheet 1 as an example. At this time, the nostril portion 16B facing the nostril and the front end portion 16 excluding the concave portion 12 are heated and bonded with a predetermined width. This heating can be performed, for example, by oscillation of ultrasonic waves by an ultrasonic vibrator.

  Accordingly, the upper right sheet 1 and the lower left sheet 2 can be bonded to each other by the adhesive material 102 at the front end portion 16 excluding the nostril portion 16B and the concave portion 12, and the three-dimensional face mask 10 having the shape shown in FIG. Is obtained.

  In addition, the adhesion process with respect to the front-end part 16 can also be performed before a punching process. In this case, as an example, the heating divided into a range from the upper end portion 14 to the portion facing the lower end of the nose bridge and a range from the portion facing between the nose and the upper lip to the lower end portion of the jaw portion 15. After heating using the member, it is punched into the shape of the right sheet 1. Thereby, the alignment of the heating part and the punching part in the sheet 101 can be facilitated.

  Further, by using a sheet containing the adhesive material 102 in the entire thickness direction over the entire surface, the application process of the adhesive material 102 and the heat treatment of the entire sheet 101 can be omitted. The adhesive material 102 does not need to be powder, and the film-like adhesive material 102 may be attached to the upper surface of the sheet 101. Moreover, you may abbreviate | omit the cutting process of FIG. 3 (B).

  Specifically, a non-woven fabric or woven fabric made of natural fibers containing thermoplastic fibers as an adhesive material, or a non-woven fabric or woven fabric made only of thermoplastic fibers as an adhesive material is used as the sheet 101. Also, one surface of a nonwoven fabric or woven fabric made of natural fibers is coated with a thermoplastic powder as an adhesive material and then heat-treated, or one surface of a nonwoven fabric or woven fabric made of natural fibers is coated with an adhesive material. A sheet 101 that is heat-treated after applying a certain thermoplastic film is used as the sheet 101.

  By these, the application | coating or sticking process of an adhesive material can be abbreviate | omitted and the cost reduction by simplification of an operation | work process is realizable.

  Further, as shown in FIG. 1, the adhesive material 102 in the sheet 101 is applied only to the outside of the line connecting the upper and lower end portions of the front end portion 16 bonded to the right sheet 1 and the left sheet 2. The coating range of 102 can be reduced. Further, by matching the shape of the application member with the shape of the joint portion, the adhesive material 102 can be applied only to the adhesion range where the application member contacts, and the application range of the adhesive material 102 can be minimized.

  In addition, the adhesive material 102 is not limited to a material having thermoplasticity, and a material that can bond the end portions of the right sheet 1 and the left sheet 2 by pressurization or a photocurable material can also be used.

  Further, as shown in FIG. 4, each of the sheet 121 for the right sheet 1 and the sheet 122 for the left sheet 2 can be pulled out from another roll 1 and overlapped. The entire surface 121 </ b> A of the sheet 121 and the surface 122 </ b> A of the sheet 122 are covered with a sheet-like adhesive material 123. As shown in FIG. 4A, the sheet 121 and the sheet 122 are overlapped with the surface 121A and the surface 122A facing each other. Thereafter, as shown in FIG. 4B, for example, an ultrasonic vibrator is used to punch the shape of the left-side sheet 2 as an example while heating the front end portion 16 excluding the nostril portion 16B and the concave portion 12 with a predetermined width. .

  As shown in FIG. 5, the three-dimensional face mask 20 manufactured by the manufacturing method according to the embodiment of the present invention is a portion facing the forehead of the right sheet 21 and the left sheet 22 (the left sheet 22 is not shown in the drawing). Tabs 211 and 221 are formed to protrude from the upper end. Other configurations are the same as those of the three-dimensional face mask 10.

  In the three-dimensional face mask 20, the base portion of the tab 211 (extension position in the left sheet 21) and the base portion of the tab 221 (right sheet 22) in a state where the inner surfaces of the right sheet 21 and the left sheet 22 are brought into contact with each other. However, the upper portion of the tab 211 does not overlap with the upper portion of the tab 221. Therefore, the tab 211 and the tab 221 are not symmetric with respect to the front end portion 16 facing the midline.

  When the three-dimensional face mask 20 is folded in half at the front end portion 16, the tab 211 and the tab 221 can be distinguished from each other. Therefore, the tab 211 and the tab 221 are grasped by the left and right fingers respectively. The left sheet 21 and the right sheet 22 can be expanded left and right. When the three-dimensional face mask 20 is used, when the left-side sheet 21 and the right-side sheet 22 are overlapped, further folded, or wound, the three-dimensional face mask 20 is impregnated with a cosmetic liquid or the like. The right sheet 22 can be easily expanded to the left and right.

  With reference to FIG. 6 (A)-(C), the manufacturing method of the solid face mask which concerns on embodiment of this invention below is demonstrated. In this manufacturing method, a sheet 111 containing a thermoplastic adhesive material at least on the entire upper surface in advance is used.

  First, as shown in FIG. 6A, the sheet 111 is pulled out from the roll, and the tab 211 and the tab 221 are cut out. Since the shapes of the tab 211 and the tab 221 are not symmetrical, the tab 211 and the tab 221 are cut out before the sheet 111 is folded in half. FIG. 6A shows a case where the right and left sheets 21 and 22 constituting the three-dimensional face mask 20 are formed so that the vertical direction is perpendicular to the drawing direction of the sheet 111.

  Next, as shown in FIG. 6B, the sheet 111 is folded in half along a center line parallel to the drawing direction.

  Thereafter, as shown in FIG. 6C, the sheet 111 folded in half is punched into the shape of the left sheet 22 as an example. At this time, the extension position of the tab 221 in the shape of the left sheet 22 is matched with both ends of the cut line of the tab 221 in the sheet 111. At the same time, the portion excluding the nostril portion 16B and the concave portion 12 in the front end portion 16 of the right sheet 21 is heated and bonded with a predetermined width. This heating can be performed, for example, by oscillation of ultrasonic waves by an ultrasonic vibrator.

  As a result, the upper left sheet 22 and the lower right sheet 21 are bonded to each other by the adhesive material contained in the sheet 111 at the front end portion 16 excluding the nostril portion 16B and the concave portion 12, and the three-dimensional face mask 20 can be obtained. The right sheet 21 does not appear in FIG.

  Note that the adhesive material is not limited to the one having thermoplasticity, and similarly to the three-dimensional face mask 10, a material that can bond the end portions of the right sheet 21 and the left sheet 22 by pressurization or a photocurable material is used. You can also.

  As with the three-dimensional face mask 10, the three-dimensional face mask 20 can also draw out a sheet for the right sheet 21 and a sheet for the left sheet 22 from different rolls and superimpose them. In this case, the tabs 211 and 221 are formed on the right-side sheet 21 and the left-side sheet 22 before being overlaid.

  In addition, the three-dimensional face mask 10 and the three-dimensional face mask 20 are both configured with a uniform thickness, but for example, another sheet may be attached to the sheet 101 or the sheet 111 for a part of the portion facing the periphery of the eyes. By sticking, the thickness may be increased to increase the content of the cosmetic liquid or the like. In this case, for example, during the steps shown in FIGS. 6A to 6C, before the tabs 211 and 221 are punched or after the tabs 211 and 221 are punched in the step of FIG. Prior to this step, another sheet having a predetermined width is pasted along the drawing direction of the sheet 111, for example, at a position facing the eyes in the sheet 111. This sticking can be performed by heating a thermoplastic adhesive material or applying an adhesive material.
