Description

Technical Field

[0001] This invention relates to a mask and a method for manufacturing the same, and more specifically, to a mask and a method for manufacturing the same by bonding a pair of ear loop components to the mask body. Background Technology

[0002] Traditionally, masks have been proposed that consist of a pair of sheet-like ear loop components glued to the mask body. For example, Figure 11 This is a plan view of mask 110, showing its unused state as seen from the skin's surface. Figure 11 As shown, in the mask 110, ear loop sheets 130a constituting a pair of ear loop components 130 are bonded to the mask body 120.

[0003] Each of the ear loop components 130 has an adhesive portion 131 and an annular portion 132. The adhesive portion 131 is bonded to the end region 121 of the mask body 120 by fusion via adhesive point 122. The annular portions 132 of the ear loop components 130 are joined together at a joining portion 134. Ear loop holes 133 are formed inside the adhesive portion 131 and the annular portion 132. When the mask 110 is used, the ear loop components 130 separate at the joining portion 134, and the ear is inserted into the ear loop hole 133.

[0004] Figure 12 This is an illustrative diagram illustrating the manufacturing process of face mask 110. (For example...) Figure 12 As shown, the mask body 120 is conveyed in the direction of arrow 140 while being held on the sheet holding surface 142 of the holding roller 141. Simultaneously, the sheet holding surface 124 of the die-cutting machine 123 conveys a continuous sheet 121b in the direction indicated by arrow 220, on which portions that will become ear loop sheets 130a are formed. Then, the mask body 120 on the holding roller 141 and the portions of the continuous sheet 121b that will become ear loop sheets 130a are placed and bonded together, and then cut into individual masks 110 (see, for example, Patent Document 1).

[0005] Patent document 1: Japanese Patent No. 5762804.

[0006] However, when the ear hook component is made of sheet material, part of the sheet material must be cut off to form the ear hook hole, which results in a waste of material.

[0007] Furthermore, the continuous sheet material used to cut off unnecessary portions to form the ear loop components is difficult to transport at high speeds. This hinders the high-speed production of masks. Summary of the Invention

[0008] The purpose of this invention is to provide a mask that can be produced with less material waste and at high speed, as well as a method for producing the mask.

[0009] The technical solution of this invention is:

[0010] To address the above problems, the present invention provides a face mask with the following structure:

[0011] A face mask comprising: (a) a single mask body having first and second peripheries extending in a first direction and third and fourth peripheries extending in a second direction intersecting the first direction; (b) a first ear loop member disposed on the surface of the mask body and bonded to a first side edge portion of the third periphery of the mask body; and (c) a second ear loop member disposed on the surface of the mask body and bonded to a second side edge portion of the fourth periphery of the mask body. The first ear loop member comprises: (i) first and second extensions, one end of which is bonded to the first side edge portion and extends along the first or second periphery in the first direction, and spaced apart from each other in the second direction; and (ii) a first connecting portion, distinct from the first and second extensions, bonded to the other end of the first and second extensions and extending in the second direction. The second ear hook component has: (i) third and fourth extensions, one end of which is bonded to a second side edge portion and extends along a first periphery or a second periphery in a first direction, and spaced apart from each other in a second direction; (ii) a second connecting portion, different from the third and fourth extensions, which is bonded to the other end of the third and fourth extensions and extends in a second direction; defining a first ear hook hole surrounded by the first and second extensions and the first connecting portion of the first ear hook component; defining a second ear hook hole surrounded by the third and fourth extensions and the second connecting portion of the second ear hook component. In the unused state, the first extension of the first ear hook component and the third extension of the second ear hook component constitute a first extension member, the second extension of the first ear hook component and the fourth extension of the second ear hook component constitute a second extension member different from the first extension member, and the first connecting portion of the first ear hook component and the second connecting portion of the second ear hook component constitute a connecting member.

[0012] According to the above structure, since the first and second extensions and the first connecting portion are different from each other, and the third and fourth extensions and the second connecting portion are different from each other, the continuous sheet of ear loop components used to form the first and second ear loop components can be configured to be conveyed at high speed, and masks can be produced at high speed. Furthermore, since it is not necessary to cut off the portion corresponding to the entire ear loop hole from the material, material waste can be reduced.

[0013] Preferably, in the mask, in the unused state, (a) in the first extension member, the other ends of the first extension of the first ear loop member and the other ends of the third extension of the second ear loop member are connected to each other at the center of the mask body along a first direction; (b) in the second extension member, the other ends of the second extension of the first ear loop member and the other ends of the fourth extension of the second ear loop member are connected to each other at the center of the mask body along a first direction; and (c) in the connecting member, the first connecting portion of the first ear loop member and the second connecting portion of the second ear loop member are connected to each other at the center of the mask body along a first direction. The other ends of the first extension of the first ear loop member and the other ends of the third extension of the second ear loop member are separable from each other at the center of the mask body in the first direction.

[0014] The other end of the second extension of the first ear loop component and the other end of the fourth extension of the second ear loop component can be separated from each other at the center of the mask body in the first direction.

[0015] The first connecting portion of the first ear loop component and the second connecting portion of the second ear loop component can be separated from each other at the center of the mask body in a first direction; when the mask is used, the first and second ear loop components are separated at the center of the mask body along the first direction.

[0016] In this situation, masks can be produced continuously and efficiently.

[0017] Preferably, when the mask is not in use, the first and second ear loop components are located on the non-skin surface side of the mask body.

[0018] In the above situations, you can avoid touching the skin surface of the mask when wearing it to ensure the mask's hygiene.

[0019] Preferably, when the mask is not in use and is viewed from a third direction perpendicular to the first and second directions, the ends of the first connecting portion of the first ear loop component and the second connecting portion of the second ear loop component protrude from the mask body on the same side in the second direction.

[0020] In this case, the ear loops can be easily separated from the mask body, making it convenient to put on the mask.

[0021] Preferably, when the mask is not in use, (a) the first connecting portion of the first ear loop component is disposed on the side opposite to the mask body of the first ear loop component and the first and second extensions of the first ear loop component, and (b) the second connecting portion of the second ear loop component is disposed on the side opposite to the mask body of the third and fourth extensions of the second ear loop component.

[0022] In this configuration, when the mask is not in use, no space is formed between the first to fourth extensions and the mask body. Furthermore, when the mask is not in use, its appearance is simple because one end of the first to fourth extensions is covered by the first and second connecting portions.

[0023] Preferably, when the mask is not in use, the first and second ear loop components are connected to each other along a first direction at the center of the mask body. When the mask is in use, the first and second ear loop components separate along the first direction at the center of the mask body and fold to the outside of the mask body along the first direction.

[0024] In this case, when wearing a mask, the first to fourth extensions are easy to unfold, and the first and second side edges of the mask body are pressed against the face, making it easy for the mask to fit tightly against the face.

[0025] Preferably, the first and second extensions of the first ear loop component and the third and fourth extensions of the second ear loop component are all formed by an elastic member that can be stretched in a first direction, sandwiched between two nonwoven sheets or between a folded nonwoven sheet.

[0026] In this case, by utilizing the tension of the elastic components, the mask body can be made to fit tightly against the face.

[0027] To address the above problems, the present invention also provides a method for manufacturing a face mask having the following structure:

[0028] A method for manufacturing a face mask comprising: (a) a single face mask body having first and second peripheries extending in a first direction and third and fourth peripheries extending in a second direction intersecting the first direction; (b) a first ear loop member bonded to a first side edge portion of the third periphery of the face mask body; and (c) a second ear loop member bonded to a second side edge portion of the fourth periphery of the face mask body, wherein the first and second ear loop members are formed by: (i) first and second extension members, which are different from each other and disposed on the surface of the face mask body and extend in a second direction at a distance spaced apart from each other along the first or second periphery, one end of which is bonded to the first side edge portion of the face mask body and the other end of which is bonded to the second side edge portion of the face mask body; and (ii) a connecting member, different from the first and second extension members, extending in the first direction at the center of the face mask body along the second direction and bonded to the first and second extension members, and defining first and second ear loop holes surrounded by the first and second extension members and the connecting member. The mask manufacturing method includes the following steps: (i) a first step: in which a continuous sheet of mask body has first and second side edges parallel to each other, wherein a first periphery of the mask body is formed by the first side edge, a second periphery of the mask body is formed by the second side edge, and a third periphery of the mask body and a fourth periphery of another mask body are simultaneously formed by cutting in a direction intersecting the first and second side edges, the mask body being conveyed in a direction extending from the first and second side edges; (ii) a second step: wherein the first and second extension continuous sheets are each continuous and different from each other in one direction, and wherein one end of the first and second extension members and the other end of the other first and second extension members are simultaneously formed by cutting in a direction intersecting the one direction, the first and second extension continuous sheets being conveyed parallel to each other at a predetermined interval in the one direction; (iii) a third step: wherein a plurality of connecting members are bonded to the first and second extension continuous sheets at predetermined intervals in the direction in which the first and second extension continuous sheets are conveyed, thereby spanning between the conveyed first and second extension continuous sheets, thereby forming an ear loop continuous sheet; (iv) a fourth step: In the fourth step, the conveyed ear loop component continuous sheet and the mask body continuous sheet are stacked on top of each other, such that the first extension continuous sheet of the ear loop component continuous sheet is along the first side edge of the mask body continuous sheet, the second extension continuous sheet of the ear loop component continuous sheet is along the second side edge of the mask body continuous sheet, and the first and second extension continuous sheets of the ear loop component continuous sheet and the mask body continuous sheet are bonded together in the middle between adjacent connecting members to form a mask continuous sheet; and (v) the fifth step: wherein the conveyed mask continuous sheet is cut in a direction intersecting the direction of conveying the mask continuous sheet to obtain individual masks.

[0029] According to the above method, the continuous ear loop component sheet formed by the continuous first extension sheet and the continuous second extension sheet can be conveyed at high speed, thus enabling high-speed manufacturing of masks. Since the continuous ear loop component sheet can be formed without cutting off the portion corresponding to the entire ear loop hole, material waste can be reduced.

[0030] Preferably, in the third step, the first and second extension continuous sheets with elastic stretchability are conveyed in a stretched state along the conveying direction of the first and second extension continuous sheets; and in the fourth step, the first and second extension continuous sheets of the ear loop component continuous sheet are conveyed in a contracted state along the conveying direction of the first and second extension continuous sheets.

[0031] In this case, a mask in which the first and second extension members are stretchable can be produced.

[0032] Preferably, the first extension continuous sheet has: between two consecutive nonwoven sheets or a folded nonwoven sheet in the conveying direction of the first extension continuous sheet; and a first elastic member sandwiched between the two nonwoven sheets or the folded nonwoven sheet, the first elastic member being stretchable and continuous in the conveying direction of the first extension continuous sheet. The second extension continuous sheet has: between two additional consecutive nonwoven sheets or another folded nonwoven sheet in the conveying direction of the second extension continuous sheet; and a second elastic member sandwiched between the additional two nonwoven sheets or the other folded nonwoven sheet, the second elastic member being stretchable and continuous in the conveying direction of the second extension continuous sheet.

[0033] In this case, the first and second extension member continuous sheets are conveyed at a higher speed than when the first and second extension member continuous sheets are formed only by elastic members, thereby enabling high-speed production of masks.

[0034] Preferably, the first extension continuous sheet has: between two continuous nonwoven sheets or a folded nonwoven sheet in the conveying direction of the first extension continuous sheet; and a first elastic member sandwiched between the two nonwoven sheets or the folded nonwoven sheet, the first elastic member being continuous in the conveying direction of the first extension continuous sheet. The second extension continuous sheet has: between two more continuous nonwoven sheets or another folded nonwoven sheet in the conveying direction of the second extension continuous sheet; and a second elastic member between the two more continuous nonwoven sheets or the other folded nonwoven sheet, the second elastic member being continuous in the conveying direction of the second extension continuous sheet. Before the fourth step, the first extension continuous sheet is stretched in the conveying direction of the first extension continuous sheet and has stretchability in the conveying direction of the first extension continuous sheet, and the second extension continuous sheet is stretched in the conveying direction of the second extension continuous sheet and has stretchability in the conveying direction of the second extension continuous sheet.

[0035] In this case, during the second and third steps, the first and second elastic members of the first and second extension continuous sheets do not need to be in a stretched state.

[0036] Preferably, the first and second extension continuous sheets conveyed in the second step are formed in such a way that the first and second elastic members are sandwiched between two continuous nonwoven sheets or between a nonwoven sheet folded and continuous along the fold line direction, spaced apart from each other so as to be continuous in the continuous direction of the two nonwoven sheets or the nonwoven sheet, thereby forming a common continuous sheet, and the common continuous sheet is cut between the first and second elastic members along the continuous direction of the first and second elastic members so as to be divided into a first extension continuous sheet including the first elastic member and a second extension continuous sheet including the second elastic member.

[0037] In this case, the first and second extension continuous sheets can be formed more efficiently than forming the first and second extension continuous sheets separately.

[0038] Preferably, the first and second elastic members are rubber threads or shrink films.

[0039] In this case, it is easy to form first and second extension members with tensile properties.

[0040] Preferably, the connecting component is formed by cutting a continuous sheet into strips.

[0041] In this case, material waste in the form of connecting components can be reduced.

[0042] Preferably, the connecting member is pre-cut into a curved shape so that the outer shapes of the two sides of the connecting member in the first direction are close to each other in the middle in the second direction.

[0043] In this case, compared to the case where the external shapes of the connecting members on both sides in the first direction are linear, the first and second ear loop components are more likely to fit the ears, making the mask less likely to fall off.

[0044] Preferably, after the third step and before the fourth step, a cut is formed in the middle of the connecting member in the direction in which the connecting member is conveyed together with the first and second extension continuous pieces, in a direction orthogonal to that direction.

[0045] In this situation, the first and second ear loop components of the mask can easily separate along the cut.

[0046] Preferably, the cut includes a perforation formed in the middle of the connecting member in the second direction.

[0047] In this case, cutting can be started from the perforation of the connecting member, making it easy to separate the first and second ear loop components.

[0048] This invention can reduce material waste and enable high-speed production of face masks. Attached Figure Description

[0061] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0062] Example 1: The following will refer to Figures 1 to 8 The mask of Embodiment 1 of the present invention and its production method are described below.

[0063] First, refer to Figures 1 to 4 The mask 10 of Embodiment 1 of the present invention will be described. Figure 1 This is a front view of the mask 10 in an unused state, viewed from the non-skin surface side. Figure 2 This is a rear view of the mask 10 in an unused state, viewed from the skin surface side. Figure 3 (a) is a schematic representation of along Figure 1 A schematic diagram of the cross-sectional structure of line AA. Figure 3 (b) schematically shows along Figure 1 A schematic diagram of the cross-sectional structure of line BB. Figure 3 (c) is a schematic representation of along Figure 1 A schematic diagram of the cross-sectional structure of line CC. Figure 4 (a) is a front view of the mask 10 in its used state, viewed from the non-skin surface side. Figure 4 (b) is a schematic representation of along Figure 4 (a) Schematic diagram of the cross-sectional structure of line XX. Schematic cross-sectional view of the mask of the present invention in its unused state (Example 1).

[0064] like Figures 1 to 3 As shown, in the unused mask 10, first and second ear loop components 11a and 11b are disposed on the non-skin surface 12s of the mask body 12. Figure 4 As shown, when the mask 10 is in use, the first and second ear loop components 11a and 11b are separated.

[0065] like Figures 1 to 4As shown, the mask body 12 has first and second periphery 12a, 12b extending along the horizontal direction (i.e., the first direction 10x) of the mask 10, and third and fourth periphery 12c, 12d extending along the vertical direction (i.e., the second direction 10y intersecting the first direction 10x) of the mask 10.

[0066] For example, a mask body 12 is formed by using a composite sheet, wherein a filter sheet is laminated between two nonwoven sheets. The composite sheet is folded so that multiple fold lines 12x, 12y extending along a first direction 10x are aligned with processing positions offset along a second direction 10y, and body adhesive portions 12m, 12n, 12u, 12v and 12w are formed along the first to fourth peripheries 12a to 12d by heat sealing (heat welding, heat fusion), ultrasonic sealing (ultrasonic welding, ultrasonic fusion) etc. (see...) Figure 2 In the composite sheet, the layers at the main adhesive portions 12m, 12n, 12u, 12v, and 12w are bonded together and integrated. Inside the mask body 12, a malleable linear fitting member 11 is disposed to extend along the first periphery 12a. The fitting member 11 is surrounded by the main adhesive portions 12m and 12w.

[0067] When the mask 10 is used, the distance between the first and second peripheries 12a and 12b is increased near the center in the first direction 10x, and the pleats formed on the mask body 12 are unfolded so that the mask body 12 becomes a semi-circular three-dimensional shape, and the fitting member 11 is deformed to conform to the shape of the nose protrusion, thereby the mask body 12 fits tightly to the face.

[0068] The mask body 12 may be properly formed using appropriate sheets only when necessary. For example, the mask body 12 may be formed from a single sheet. The sheet constituting the mask body 12 may not be pleated.

[0069] The first ear loop component 11a has first and second extensions 14a and 16a that are spaced apart from each other in the second direction 10y and extend along the first direction 10x, and a first connecting portion 18a that extends along the second direction 10y. The first extension 14a extends along the first periphery 12a of the mask body 12, while the second extension 16a extends along the second periphery 12b of the mask body 12. One end 14p, 16p of the first and second extensions 14a and 16a is bonded to the first side edge 12p adjacent to the third periphery 12c of the mask body 12 by a first side edge adhesive portion 22a. The first connecting portion 18a is bonded to the other ends 14s, 16s of the first and second extensions 14a and 16a by a first center adhesive portion 20a. The first connecting portion 18a is different from the first and second extensions 14a and 16a.

[0070] The second ear loop component 11b has third and fourth extensions 14b and 16b that are spaced apart from each other in the second direction 10y and extend along the first direction 10x, and a second connecting portion 18b that extends along the second direction 10y. The third extension 14c extends along the first periphery 12a of the mask body 12, while the fourth extension 14d extends along the second periphery 12b of the mask body 12. One end 14q and 16q of the third and fourth extensions 14c and 16d are bonded to the second side edge 12q adjacent to the fourth periphery 12d of the mask body 12 by means of the second side edge adhesive portion 22b. The second connecting portion 18b is bonded to the other ends 14t and 16t of the third and fourth extensions 14c and 16d by means of the second center adhesive portion 20b. The second connecting portion 18b is different from the first and second extensions 14b and 16b.

[0071] First and second side edge adhesive portions 22a, 22b and first and second center adhesive portions 20a, 20b are formed by ultrasonic sealing or heat sealing.

[0072] The first and second ear loop components 11a and 11b are formed by a first extension member 14, a second extension member 16 and a connecting member 18 that are different from each other, and are separably connected to each other at the center of the mask body 12 in a first direction 10x.

[0073] The first extension member 14 constitutes the first extension 14a of the first ear loop member 11a and the third extension 14b of the second ear loop member 11b, and is configured such that the other ends 14s and 14t of the first and third extensions 14a and 14b are separably connected to each other at the center of the mask body 12 in the first direction 10x.

[0074] The second extension member 16 constitutes the second extension 16a of the first ear loop member 11a and the fourth extension 16b of the second ear loop member 11b, and is configured such that the other ends 16s and 16t of the second and fourth extensions 16a and 16b are separably connected to each other at the center of the mask body 12 in the first direction 10x.

[0075] like Figure 1 and 3 As shown in (a), the first and second extension members 14, 16 are members in which first and second elastic members 15, 17, which are extendable and continuous in a first direction 10x, are sandwiched between nonwoven sheets 50, 52. The nonwoven sheets 50, 52 are folded along fold lines 50x, 52x; 52s, 52t, between a pair of side edges 50s, 50t. The first and second extension members 14, 16 can be members in which elastic members 15, 17, which are extendable and continuous in the first direction 10x, are sandwiched between two nonwoven sheets, as in the second variation described later.

[0076] Figure 1 and Figure 2 The illustration shows the side edges 50t and 52t of the extension members 14 and 16 configured to coincide with the peripheries 12a and 12b of the mask body 12. The invention is not limited thereto; the side edges 50t and 52t of the extension members 14 and 16 may protrude beyond the mask body 12, or the side edges 50t and 52t of the extension members 14 and 16 may be located inside the peripheries 12a and 12b of the mask body 12.

[0077] Nonwoven sheets 50 and 52 and elastic members 15 and 17 are bonded together at portions of a plurality of first and second side edge adhesive portions 22a and 22b and portions of a plurality of first and second center adhesive portions 20a and 20b. Specifically, elastic members 15 and 17 are bonded to the nonwoven sheets 50 and 52 at both ends of extensions 14a, 14b and 16a, 16b. Elastic members 15 and 17 are rubber threads, shrink films, etc. There may be more than one elastic member 15 and 17, for example, more than one rubber thread.

[0078] The connecting member 18 constitutes the first connecting portion 18a of the first ear loop member 11a and the second connecting portion 18b of the second ear loop member 11b, and is configured such that the centers of the first and second connecting portions 18a and 18b are separably connected to each other in the first direction 10x. That is, the adjacent side edges 18m and 18n of the first and second connecting portions 18a and 18b (see...) Figure 4 The first and second connecting portions 18a and 18b are connected to each other. The side edges 18u and 18v on the opposite sides of the first and second connecting portions 18a and 18b are bent so that the middle portions in the second direction 10y are close to each other.

[0079] On the connecting member 18, perforations 30 and slits 32 extending along a second direction 10y are formed at the center of the mask body 12 in a first direction 10x. The perforations 30 are multiple cuts passing through the main surfaces of the connecting member 18 and are formed in the middle portion of the connecting member 18 in the second direction 10y. Slits 32 are formed on both sides of the perforations 30 so as to be aligned with the perforations 30 in a straight line. The slits 32 may be formed passing through the main surfaces of the connecting member 18, or may be formed from one main surface of the connecting member 18 just before the other main surface. The cuts may be formed appropriately; for example, the perforations 30 may be formed on both sides of the slits 32 aligned with the slits 32 in a straight line, or only either the perforations 30 or the slits 32 may be formed.

[0080] like Figure 1 and 2As shown, when the mask 10 in its unused state is viewed from a direction perpendicular to the first and second directions 10x and 10y, the ends 18p, 18q; 18s, 18t on both sides of the first and second connecting portions 18a, 18b protrude from the mask body 12 in the second direction 10y. This allows the first and second connecting portions 18a, 18b to be easily separated from the mask body 12, and also allows the first and second ear loop components 11a, 11b to be easily separated. The first and second ear loop components 11a, 11b are also easily separated when only any one of the ends 18p, 18q and the ends 18s, 18t protrudes from the mask body 12. A structure in which the ends 18p, 18q; 18s, 18t of the first and second connecting portions 18a, 18b do not protrude from the mask body 12 is also possible.

[0081] To facilitate the separation of the first and third extensions 14a, 14b and the second and fourth extensions 16a, 16b, notches, slits, etc., can be formed on the first and second extension members 14, 16; or the elastic members 15, 17 can be pre-cut.

[0082] like Figure 1 and Figure 3 As shown, when the mask 10 is in an unused state, the connecting member 18 is disposed on the side of the first and second extension members 14, 16 opposite to the mask body 12, and no space is formed between the first and second extension members 14, 16 and the mask body 12. Since the connecting member 18 covers the adjacent ends 14s, 14t of the first and third extensions 14a, 14b and the adjacent ends 16s, 16t of the second and fourth extensions 16a, 16b, the appearance near the center in the first direction 10x is simple. A structure can be adopted in which, when the mask 10 is in an unused state, the connecting member 18 is disposed on the side of the first and second extension members 14, 16 opposite to the mask body 12.

[0083] When the mask 10 is used, the first and second ear loop components 11a and 11b are separated. That is, the connecting member 18 is cut along the perforation 30 and the slit 32 to separate the first and second connecting portions 18a and 18b, the first extension member 14 is cut to separate the first and third extension portions 14a and 14b, and the second extension member 16 is cut to separate the second and fourth extension portions 16a and 16b.

[0084] like Figure 4As shown, in the mask 10 in use, the first and second ear loop components 11a and 11b are separate and unfold towards opposite sides of each other in the first direction 10x toward the outside of the mask body 12, and the first and second ear loop components 11a and 11b are folded onto the mask body 12. The first and second ear loop holes 13a and 13b are defined by the first and third extensions 14a and 14b, the second and fourth extensions 16a and 16b, and the connecting portions 18a and 18b of the first and second ear loop components 11a and 11b, and the ears are inserted into these first and second ear loop holes 13a and 13b.

[0085] When wearing the mask 10, it is more comfortable to wear than when the side edges 18u, 18v of the first and second ear loop parts 11a, 11b along the wearer's ears are straight, because the side edges 18u, 18v are curved.

[0086] The mask 10 is hygienic because the first and second ear loop components 11a and 11b are positioned on the non-skin surface 12s side of the mask body 12 when not in use, and for this reason, the mask 10 can be worn without contacting the skin surface 12t of the mask body 12. A structure in which the first and second ear loop components 11a and 11b are positioned on the skin surface 12t side of the mask body 12 when not in use is possible.

[0087] In the mask 10, since the first and second extensions 14a, 16a and the first connecting portion 18a are different from each other, and the third and fourth extensions 14b, 16b and the second connecting portion 18b are different from each other, the ear loop member continuous piece 56 (described later) used to form the first and second ear loop members 11a, 11b can be configured such that the portions forming the first and third extensions 14a, 14b and the portions forming the second and fourth extensions 16a, 16b are continuous. Since the ear loop member continuous piece 56 (described later) constructed as described above can be conveyed at high speed and does not hinder the high-speed production of the mask 10, the mask 10 can be produced at high speed. Therefore, the number of masks 10 produced per unit time can be increased.

[0088] Furthermore, since the first and second extensions 14a, 16a and the first connecting portion 18a are different from each other, and the third and fourth extensions 14b, 16b and the second connecting portion 18b are different from each other, it is not necessary to cut portions of material corresponding to the entire ear loop holes 13a, 13b. For this reason, material waste can be reduced.

[0089] Next, we will refer to Figures 5 to 8 Describes a method for producing face masks 10. Figure 5This is an explanatory diagram of the steps for forming the first and second extension continuous sheets 51 and 53. Figure 6 This is a step diagram illustrating the process of forming the continuous piece 56 of the ear hook component. Figure 7 This is a diagram illustrating the steps involved in forming a continuous sheet 60 of a mask to obtain a single mask 10.

[0090] The method for producing face mask 10 generally includes first and second steps.

[0091] In the first step, such as Figure 7 As shown in (a), a continuous sheet 58 of the mask body having first and second side edges 58p and 58q parallel to each other is conveyed in a direction extending from the first and second side edges 58p and 58q. The first side edge 58p forms the first periphery 12a of the mask body 12, and the second side edge 58q forms the second periphery 12b of the mask body 12. By cutting the continuous sheet 58 of the mask body in a direction intersecting the first and second side edges 58p and 58q, a third periphery 12c of the mask body 12 and a fourth periphery 12d of another mask body 12 are formed.

[0092] For the continuous sheet 58 of the mask body, for example, during conveying, a continuous sheet having one or more layers is folded such that the fold line 58x extends in the conveying direction, and then integrated at appropriate locations by means of ultrasonic sealing, heat sealing, etc., thereby forming the main adhesive parts 12m, 12n, 12u, 12v, 12w (see... Figure 1 , 2 4. Figure 7 (Not shown in the image).

[0093] In the second step, such as Figure 5 As shown in (d), the first and second extension continuous sheets 51 and 53, which are continuous in one direction, are conveyed parallel to each other at a predetermined distance from each other and at the same speed in their continuous direction. By cutting the first and second extension continuous sheets 51 and 53 in a direction intersecting their continuous direction, one end 14p and 16p of the first and second extension members 14 and 16 and the other end 14q and 16q of the first and second extension members 14 and 16 are formed.

[0094] The first and second extension continuous sheets 51, 53 are manufactured using a nonwoven fabric sheet 54, for example, as Figure 5 As shown.

[0095] First, such as Figure 5 As shown in (a), a strip of nonwoven fabric 54 having a pair of main surfaces 54s, 54t parallel to each other and a pair of side edges 54p, 54q is conveyed in a direction where the side edges 54p, 54q are continuous.

[0096] Then, as Figure 5 As shown in (b), first and second elastic members 15 and 17, indicated by double-dotted lines and in a stretched state, are provided on a main surface 54s of the nonwoven sheet 54 being conveyed, and are conveyed together with the nonwoven sheet 54. The first and second elastic members 15 and 17 are arranged parallel to the conveying direction of the nonwoven sheet 54 and are spaced apart from each other by a certain distance. The elastic members 15 and 17 are rubber threads, shrink films, etc. There may be more than one elastic member 15 and 17, for example, more than one rubber thread.

[0097] Then, as Figure 5 As shown in (c), the nonwoven sheet 54 is folded along fold lines 54m and 54n, such that the side edges 54p and 54q of the nonwoven sheet 54 are arranged at a certain distance from each other on a main surface 54s of the nonwoven sheet 54, thereby forming a common continuous sheet 55, wherein elastic members 15 and 17 are sandwiched between the nonwoven sheets 54.

[0098] Then, as Figure 5 As indicated by the dotted line 54x in (c), a common continuous sheet 55 is cut along the conveying direction between the side edges 54p and 54q of the nonwoven sheet 54 to divide it into a first extension continuous sheet 51 including a first elastic member 15 and a second extension continuous sheet 53 including a second elastic member 17. Then, as... Figure 5 As shown in (d), the positions of the first and second extension continuous sheets 51 and 53 are changed so that the fold lines 54m and 54n face each other, and the first and second extension continuous sheets 51 and 53 are conveyed at a predetermined distance from each other, parallel to each other, and at the same speed.

[0099] It is effective to form the first and second extension continuous sheets 51, 53 by forming and separating the common continuous sheet 55. However, the first and second extension continuous sheets 51, 53 can be formed separately.

[0100] In the third step, such as Figure 6 As shown in (a), multiple connecting members 18 are bonded to the first and second extension continuous sheets 51, 53 by ultrasonic sealing, heat sealing, etc., so that they span the first and second extension continuous sheets 51, 53 at a predetermined distance in the direction of transmission of the first and second extension continuous sheets 51, 53, thereby forming an ear loop member continuous sheet 56. The bonding at this time forms the first and second central adhesive portions 20a, 20b. Specifically, the following portions are formed: in the nonwoven fabric sheet 54 forming the first and second extension continuous sheets 51, 53 and the first and second elastic members 15, 17, only the portion of the nonwoven fabric sheet 54 bonded to the connecting member 18; and the portion of the nonwoven fabric sheet 54 bonded together with the first or second elastic member 15 or 17 and the connecting member 18.

[0101] Figure 8 This is a schematic diagram illustrating the steps involved in forming the connecting member 18. The connecting member 18 is formed by cutting the continuous sheet 70 into strips, thus reducing material waste compared to punching the continuous sheet 70 one strip at a time. Figure 8 As the continuous strip 70 shown in (a) is conveyed along its length, unnecessary portions are removed to form a pair of side edges 72, 74 and a hollow hole 76, as shown. Figure 8 As shown in (b). Then, as Figure 8 As indicated by the dotted line 60x in (b), a continuous piece 70 is cut at the position where the hollow hole 76 is divided into two halves, thereby obtaining the following... Figure 8 (c) shows a single connecting member 18. The side edges 18u, 18v of the connecting member 18, formed by the inner periphery of the cut hollow hole 76, are curved so that they are close to each other in the middle portion. By continuously cutting the continuous sheet 70 into strips and conveying the connecting members 18 obtained by cutting at predetermined intervals, the connecting members 18 can be bonded to the first and second extension continuous sheets 51, 53 at predetermined intervals, so that the formation of the continuous sheet can be synchronized with the formation of the ear hook component continuous sheet 56.

[0102] Then, as Figure 6 As shown in (b), aligned perforations 30 are made in a direction perpendicular to the conveying direction, i.e., near the center of the connecting member 18, forming multiple cuts between the main surfaces of the connecting member 18, and the connecting member 18 is bonded to the first and second extension continuous pieces 51, 53.

[0103] Then, as Figure 6 As shown in (c), slits 32 are formed on both sides of the perforation 30. The slits 32 may be formed only on the connecting member 18, or they may be formed on the connecting member 18 and the first and second extension continuous pieces 51, 53. The slits 32 may be cuts that pass through the connecting member 18 and the first and second extension continuous pieces 51, 53, or they may be cuts that are formed in the middle instead of passing through.

[0104] The perforation 30 and the slit 32 are formed such that the two sides clamping the perforation 30 and the slit 32 are connected to each other. By forming the perforation 30 and the slit 32 on the connector 18, the first and second ear hook parts 11a, 11b can be easily separated along the perforation 30 and the slit 32.

[0105] However, masks can be produced without forming perforations 30 or slits 32. In this case, the first and second ear loop components 11a, 11b that are connected to each other need to be cut, for example, by using a cutter, scissors, etc., to separate the first and second ear loop components 11a, 11b.

[0106] Then, as Figure 6 As shown in (d), the first and second extensions 51 and 53 of the ear loop component continuous sheet 56 contract in the transport direction, thereby releasing the elastic members 15 and 17 from the stretched state. By doing so, the distance L between adjacent connecting members 18 is reduced. Since the first and second extensions 51 and 53 have elastic extensibility, the first and second extensions 51 and 53 can contract.

[0107] In the fourth step, such as Figure 7 As shown in (b), the conveyed ear loop component continuous sheet 56 and the mask body continuous sheet 58 are stacked on top of each other, such that the first extension continuous sheet 51 of the ear loop component continuous sheet 56 is along the first side edge 58p of the mask body continuous sheet 58, and the second extension continuous sheet 53 of the ear loop component continuous sheet 56 is along the second side edge 58q of the mask body continuous sheet 58, and as... Figure 7 As shown in (c), in the middle between adjacent connecting members 18, the first and second extension continuous pieces 51, 53 of the ear loop component continuous piece 56 and the mask body continuous piece 58 are bonded together by ultrasonic sealing, heat sealing, etc., thereby forming a mask continuous piece 60. The bonding at this time forms the first and second side edge adhesive portions 22a, 22b. Specifically, the following portions are formed: among the nonwoven fabric sheets 54 constituting the first extension continuous pieces 51, 53 of the ear loop component continuous piece 56 and the first and second elastic members 15, 17, only the portion of the nonwoven fabric sheet 54 is bonded to the mask body continuous piece 58; and the portion of the nonwoven fabric sheet 54 and the first or second elastic member 15 or 17 are bonded to the mask body continuous piece 58.

[0108] When the ear loop component continuous piece 56 and the extension continuous pieces 51 and 53 of the mask body continuous piece 58 are stacked on each other, the side edges 51x and 53x on the opposite sides of the extension continuous pieces 51 and 53 (see...) Figure 7 (b) can be attached to the side edges 58p and 58q of the continuous piece 58 of the mask body (see... Figure 7 (a) The overlap can extend to the outside of the continuous piece 58 of the mask body, or it can be located inside the side edges 58p and 58q of the continuous piece 58 of the mask body.

[0109] In the fifth step, such as Figure 7 As indicated by the dotted line 60x in (c), the conveyed mask continuous sheet 60 is cut along a direction intersecting with (e.g., an orthogonal direction) the direction of the conveying mask continuous sheet 60, thereby obtaining the following... Figure 7 (d) shows a single mask 10.

[0110] The third and fourth peripheries 12c and 12d of the mask body 12 are formed by cutting the mask body continuous piece 58 of the mask continuous piece 60. The first and second extension members 14 and 16 of the mask body 12 are formed by cutting the first and second extension continuous pieces 51 and 53 of the mask continuous piece 60.

[0111] When the first and second elastic members 15 and 17 are released from the stretched state in the fourth step, the mask 10 is obtained in the fifth step in a flat state, wherein the first and second stretching members 14 and 16 with elasticity are arranged along the mask body 12.

[0112] By using the above method to produce the mask 10, the continuous ear loop component 56 of the first and second extension continuous sheets 51, 53 can be conveyed at high speed, thereby enabling high-speed production of the mask 10. Furthermore, the continuous ear loop component 56 can be formed without cutting off portions corresponding to the entire ear loop holes 13a, 13b, thereby reducing material waste.

[0113] The first and second extension continuous sheets 51, 53 can be stretched in the direction in which they are conveyed before the fourth step, thus possessing stretchability. For stretching, for example, the first and second extension continuous sheets 51, 53 or the ear-hook component continuous sheet 56 are conveyed while being clamped between a pair of rollers having uneven outer peripheral surfaces that mesh with each other.

[0114] In this case, the first and second elastic members 15 and 17 need not be in a stretched state in the second and third steps, and the first and second extensions 51 and 53 of the ear loop member continuous piece 56 need not be contracted in the transmission direction before the fourth step.

[0115] Variation Example 1: Figure 9 and 10 This is an explanatory diagram showing a first modified example of the steps for forming the first and second extension continuous sheets, and is a schematic diagram of a cross section in the width direction.

[0116] The first and second extension continuous sheets can be formed as follows: Figure 9 As shown in (a), the first and second elastic members 15 and 17 are disposed on a side edge 62q of a nonwoven sheet 62, and then, as Figure 9 As shown in (b), the other edge 62p of the nonwoven sheet 62 is folded to sandwich the first and second elastic members 15, 17 between the nonwoven sheet 62, and the nonwoven sheet 62 is cut between the first and second elastic members 15, 17 as indicated by the dotted line 62y.

[0117] The first and second extension continuous sheets can be formed as follows: Figure 9 As shown in (c), the first and second elastic members 15 and 17 are sandwiched between two nonwoven sheets 64a and 64b, and the nonwoven sheets 64a and 64b are cut at the position indicated by the dotted line 64x between the first and second elastic members 15 and 17. In this case, as Figure 10 As shown in (a), two nonwoven sheets 64a, 64b can be obtained by cutting and separating a nonwoven continuous web 64 along the length direction at the position indicated by the dotted line 64y.

[0118] The first and second extension continuous sheets can be formed as follows: Figure 9 As shown in (d), the elastic member 66 is sandwiched between a nonwoven sheet 62 folded between one side edge 62p and the other side edge 62q, and the nonwoven sheet 62 and the elastic member 66 are cut and separated at the position indicated by the dotted line 62y.

[0119] The first and second extension continuous sheets can be formed as follows: Figure 9 As shown in (e), the elastic member 66 is sandwiched between a nonwoven sheet 62 folded between one side edge 62q and the other side edge 62p, and the nonwoven sheet 62 and the elastic member 66 are cut and separated at the position indicated by the dotted line 62x.

[0120] The first and second extension continuous sheets can be formed as follows: Figure 9 As shown in (f), the elastic member 66 is sandwiched between two nonwoven fabric sheets 64a and 64b, and the nonwoven fabric sheets 64a and 64b and the elastic member 66 are cut and separated at the position indicated by the dotted line 64x. In this case, as Figure 10 As shown in (a), two nonwoven sheets 64a, 64b can be obtained by cutting and separating a nonwoven continuous web 64 along the length direction at the position indicated by the dotted line 64y.

[0121] The first and second extension continuous sheets can be formed as follows: Figure 10 As shown in (b), a continuous nonwoven web 64 is cut along its length at three locations indicated by the dotted line 64z to form four nonwoven sheets 64k, and then, as... Figure 10 As shown in (c), the first and second elastic members 15 and 17 are each sandwiched between two nonwoven fabric sheets 64k.

[0122] Variation 2: When producing a mask with rubber threads as elastic members 15, 17 disposed on the extension members 14, 16 constituting extensions 14a, 14b; 16a, 16b, the first and second extension continuous sheets 51, 53 can be formed as follows: the rubber threads are stretched, and with the rubber threads sandwiched between nonwoven sheets, the rubber threads and the nonwoven sheets are intermittently fused together in the conveying direction by ultrasonic waves or heat. In this case, it is not necessary to bond the rubber threads and the nonwoven sheets together in the first and second side edge adhesive portions 22a, 22b and the first and second central adhesive portions 20a, 20b.

[0123] In summary, based on the above-mentioned masks and methods for their production, material waste can be reduced and masks can be produced at high speed.

[0124] This invention is not limited to the above embodiments and can be implemented with various modifications.

[0125] For example, the mask of the present invention can be produced by a method different from that described above. The mask body can have a shape other than a rectangle. For example, the angle between the first and second peripheries of the mask body and the third and fourth peripheries can be acute or obtuse. Furthermore, the periphery of the mask body can be curved, or it can have a shape with repeated folded portions and / or curved portions.
