  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 12 show a first embodiment in which the present invention is applied to a face mask 1.

  The face mask 1 is an example of a pack sheet. As shown in FIGS. 1 to 4, the face mask 1 is composed of a sheet body 2 having high water absorption, such as nonwoven fabric impregnated with a cosmetic liquid, paper, and the like. At least a pair of unfolding knobs 3 for projecting outward are integrally formed on the left and right sides of the outer periphery. Each knob 3 is reinforced by a reinforcing material provided on one side thereof, for example, a reinforcing film 4 made of synthetic resin bonded to one side of the knob 3 by bonding or heat sealing.

  The sheet body 2 has a size that covers substantially the entire face, and is formed in a substantially circular shape, a rice ball shape, or another predetermined shape. And in the required location of the sheet | seat body 2, in order to improve the adhesiveness with respect to a face, several notches 5-8 are formed. For example, on the inner side of the sheet body 2, notches 5 and 6 such as slits are formed in a U-shaped portion corresponding to the eyes and nose of the face, and inverted U-shaped, and notches 7 such as openings are formed in a portion corresponding to the mouth. In addition, cuts 8 such as slits are formed radially at appropriate locations such as up and down, left and right on the outer periphery.

  Of the pair of knobs 3, one knob 3 is above the approximate center in the vertical direction of the sheet body 2, and the other knob 3 is below the approximate center in the vertical direction of the sheet 2. As shown in FIG. 4A, when the sheet body 2 is folded in a double-folded manner at a substantially centered folding line 9 in the left-right direction, the tabs 3 are vertically It is close to the top and bottom without overlapping at the approximate center of the direction.

  The reinforcing film 4 that reinforces each knob 3 is made of a synthetic resin film having appropriate elasticity and shape retention, and is provided corresponding to the shape of the knob 3. This reinforcing film 4 is provided with a strip-shaped extending portion 4a in the vertical direction on the inner end side thereof. The extending part 4 a slightly enters the sheet body 2 side from the knob part 3 and extends to both the upper and lower sides, and the outer side excluding the knob part 3 is along the outer shape of the sheet body 2.

  Both knobs 3 may be provided at a position where a part of the knobs 3 overlap when folded in two as shown in FIG. Of course, it is also possible to provide both the knobs 3 so that they substantially coincide. Further, the cuts 5 to 8 are formed in the sheet body 2 at substantially left and right symmetrical positions, but may be asymmetrical. The extending part 4a may be only one of the upper side and the lower side in addition to the upper and lower sides. Further, the length of the extended portion 4a may be set so as to be closer to the knob portion 3 side than the folding line of the sheet body 2. The reinforcing film 4 may extend to the boundary between the knob portion 3 and the sheet body 2 as shown by a two-dot chain line in FIG. 1, and the extension portion 4a may be eliminated.

  5 to 8 exemplify a face mask package 11 in which the face mask 1 is folded and sealed one by one in a wrap-wrap shape by the packaging bag 10. The face mask package 11 is an example of a pack sheet package. As shown in FIGS. 5 to 8, the face mask 1 is folded in two by folding the face mask 1 at the center folding line 9 at the left and right sides. The folded body 12 and the outer packaging film 13 are folded in a flat shape at a plurality of folding lines 14 and 15 in the direction of the folding line 9 and wrapped in a wrap-wrap shape. The packaging bag 10 is formed by sealing so as to be peeled off by the vertical seal portion 16 and the horizontal seal portion 17. For the packaging film 13, an easy peel film or other appropriate thin film is used.

At the time of packaging, as shown in FIG. 8, the folded body 12 of the face mask 1 is overlaid on the packaging film 13 (see FIG. 8A), and along the folding line 18 near the end of the folded body 12. after heavy proof folding packaging film 13 on the inner side (see FIG. 8 (B)), two-folded line 9 direction at two positions, for example, a pair of knob portions 3 on the opposite side of the clamshell line 9 clamshell 12 It is folded in a tri-fold shape that is flat in one direction along two folding lines 14 and 15 on both sides of the.

  Accordingly, as shown in FIG. 6, the folded body 12 of the face mask 1 has an inner portion 12b on one end side thereof superimposed on the intermediate portion 12a, and an outer portion on the other end side of the intermediate portion 12a on the inner portion 12b. 12c is folded in three, and the inner end side of the packaging film 13 is wound around the inner end portion of the inner side portion 12b from both the inner and outer sides. The space between the two folding lines 14 and 15 is such that the pair of knobs 3 are sandwiched from both sides, and the inner part 12b and the outer part 12c of the folded body 12 overlap each other with the packaging film 13 inside and outside. It has become.

  The packaging film 13 has a lateral seal portion 17 on both sides in the direction of the fold lines 14 and 15 with respect to the face mask 1 and an outer end portion of the packaging film 13 between the lateral seal portions 17 along the edge. It is sealed in a sealed manner with a vertical seal portion 16 that seals the packaging film 13. The packaging film 13 constitutes one packaging bag 10.

  In the vertical seal portion 16, a pressure-sensitive hot melt adhesive 19 or the like is applied along the outer edge of the packaging film 13 slightly inside the edge, and the pressure-sensitive hot melt adhesive 19 or the like is applied. The outer end portion of the packaging film 13 is heat-sealed so as to be peelable to the outside of the inner packaging film 13. Moreover, in the horizontal seal part 17, the overlapping part of the packaging films 13 is sealed so as to be peelable by heat welding, heat sealing, or other appropriate sealing methods. In addition, it is desirable that each seal part is easily peeled and bonded in order to facilitate opening of the packaging bag 10. However, when the packaging film 13 is a thin film that is easily broken when opened, the vertical seal portion 16 and the horizontal seal portion 17 do not need to be peelable.

  In the face mask package 11, when the face mask 1 is taken out from the packaging bag 10 and used, the outer edge 13 a of the packaging film 13 is picked and the packaging bag 10 is opened from the vertical seal portion 16 side. At the time of opening, first, the vertical seal portion 16 is peeled off, and then the horizontal seal portion 17 is sequentially peeled in the circumferential direction (the direction of the folding line 9), so that the folded body 12 of the face mask 1 is opened while the packaging bag 10 is opened. Can be easily expanded in a double fold.

  Since both the inner and outer ends of the bi-fold body 12 of the face mask 1 are in contact with other opposing portions of the bi-fold body 12 via the packaging film 13, the end portions of the bi-fold body 12 are in close contact with the other opposing portions. Thus, the end of the folded body 12 can be easily separated from the packaging film 13, and handling when the packaging bag 10 is opened and expanded into an unfolded form is very easy.

  After expanding to the half-folded shape, each tab 3 is held and the left half and the right half of the sheet body 2 are peeled off and expanded. In this case, the sheet body 2 and the knob part 3 are in a wet state impregnated with the cosmetic liquid, but the knob part 3 protruding outward from the sheet body 2 is reinforced by the reinforcing film 4, so the knob part. There is no problem such as the folding of 3 and each knob 3 can be easily distinguished. And since each knob | pick part 3 is reinforced with the reinforcement film 4, and there exists a preserving in the knob | pick part 3 itself, each knob | pick part 3 can be easily picked. Therefore, it is possible to easily expand and unfold the folded sheet body 2 as compared with the conventional case.

  Further, when the reinforcing film 4 has a thin extending portion 4a such as a vertical strip, the sheet body 2 can be reinforced in the vicinity of the top and bottom of the knob portion 3 by the extending portion 4a. For this reason, although the sheet body 2 has a plurality of cuts 5 to 8, the sheet body 2 can be further easily expanded.

  Even when the face mask 1 is applied to the face in an expanded state, each knob 3 is reinforced by the reinforcing film 4, and the sheet body 2 near the upper and lower sides of each knob 3 is reinforced by the extension 4a. Therefore, it is possible to easily carry the face mask 1 in a state in which each of the knobs 3 is picked and spread to the face. Further, since the reinforcing film 4 is adhered to the knob portion 3 by adhesion or heat sealing and the reinforcing film 4 is reinforced as a reinforcing material, the structure is very simple and can be manufactured easily and inexpensively. .

  9 and 10 illustrate a manufacturing process in the case of manufacturing the face mask 1 from the raw sheet material 20. The original fabric sheet material 20 is fed out from an original fabric roll 21 wound in a roll shape and sent in the longitudinal direction. Then, the face mask 1 is sequentially manufactured through, for example, a reinforcing film sticking step 22, a face mask cutting step 23, a face mask removing step 24, a trim collecting step 25 and the like while feeding the raw sheet material 20 in the longitudinal direction.

  In the reinforcing film sticking step 22, the reinforcing film pieces 28 having a predetermined size are sequentially stuck to the grip portion cutting planned portions 27 on both sides of the sheet body cutting planned portion 26 of the raw sheet material 20. The sheet body cutting scheduled portions 26 are set so as to be close to each other at a predetermined interval in the longitudinal direction of the original fabric sheet material 20, and each knob portion cutting planned portion 27 is located on the original fabric sheet material 20 with respect to the sheet body cutting planned location 26. It is on both sides of the diagonal direction intersecting the longitudinal direction. Then, as shown in FIG. 10 (B), a slightly larger reinforcing film piece 28 is attached to each knob part planned cutting location 27 so that a part thereof enters the sheet cutting planned site 26. To do.

  When the raw film sheet 20 passes between a pair of sticking rolls, the reinforcing film piece 28 is formed at the picking portion 27 to be cut out at a pitch corresponding to the pitch between the cutting portions 26 adjacent to each other in the longitudinal direction. Adhere by adhesion, heat sealing, etc. For example, when the reinforcing film piece 28 is attached to the raw sheet material 20 by a heat sealing method, it may be attached with a whole surface seal, a point seal, a line seal, a string-type seal, O You may stick so that it may become a mark pattern and a knurled pattern. Of course, any bonding method or heat sealing method can be used as long as it can bond or seal the raw fabric sheet material 20 such as a nonwoven fabric and the reinforcing film piece 28 by applying heat and pressurizing regardless of these. It may be adopted.

  In the face mask cutting step 23, the raw sheet material 20 after the reinforcing film piece 28 is adhered is fed between a pair of carter rolls, and the face mask 1 is cut by the carter rolls. The carter roll has a cutting blade corresponding to the outer peripheral shape of the face mask 1 including the sheet body 2 and the pair of knobs 3, and a cutting blade corresponding to each cut, and the raw sheet material 20 is a pair of carters. When passing through the roll, the face mask 1 is cut from the raw sheet material 20 by the cutting blade.

  In this case, when the sheet body cut scheduled portion 26 and the knob portion scheduled cut portion 27 of the original fabric sheet material 20 are cut and the sheet body 2 with the knob portion 3 is cut from the original fabric sheet material 20, the original fabric sheet is cut. The reinforcing film piece 28 is cut out along the shape of each of the knobs 3 together with the scheduled cutout portions 27 of the material 20. For this reason, the shape of the reinforcing film 4 corresponds to the knob portion 3.

  Since the face mask 1 is cut off in a state in which the face mask 1 is oriented obliquely with respect to the longitudinal direction of the original fabric sheet material 20, the yield of the face mask 1 with respect to the original fabric sheet material 20 is improved, and waste of materials can be prevented as much as possible. In addition, in order to cut out the knob portion 3 from the raw sheet material 20 together with the reinforcing film piece 28, a sticking of a reinforcing film piece 28 of a size covering the respective knob portion 27 to be cut out is provided. The waste of the reinforcing film piece 28 can also be prevented as compared with the case where a strip-like reinforcing film piece continuous in the longitudinal direction of the raw sheet material 20 is used.

  In the face mask removing step 24, each time the face mask 1 is cut out from the raw sheet material 20 in the face mask cutting step 23, the face mask 1 is taken out and transported to the next packaging step. In the trim collection step 25, the trim 29 after the face mask 1 is cut off is collected by winding up. The cosmetic liquid impregnation step is performed before the reinforcing film adhering step 22 for adhering the reinforcing film piece 28 to the raw fabric sheet material 20 or between the reinforcing film adhering step 22 and the face mask cutting step 23. Or before the packaging process.

  The face mask 1 is large enough to cover the face, is very large in the unfolded state, and is impregnated with a cosmetic liquid, so that the face mask 1 is packaged in a sealed state in a folded state folded into a predetermined size. In that case, in consideration of the usage pattern of the face mask 1, the sheets may be individually wrapped in the packaging bag 10, or may be wrapped in a state where several sheets or a plurality of more than one are stacked together. The bag 10 may be used for packaging.

  11 and 12 exemplify a packaging process in the case where the face mask 1 impregnated with the cosmetic liquid is wrapped on the sheet body 2 while being folded one by one. For the packaging of the face mask 1, a belt-like packaging film 13 is used, and this is fed out from a roll roll 31 and fed in the longitudinal direction. After the process 34, the folding process 35, the wrapping process 36, the sealing process 37, the face mask package take-out process 38, etc., it is packaged and finished as the face mask package 11.

  In the adhesive application process 32, the pressure-sensitive hot melt adhesive 19 for vertical sealing is applied to one end in the width direction of the packaging film 13 running in the longitudinal direction by a coating means such as a coating nozzle or a coating roll. It is applied in a strip shape along the longitudinal direction. The pressure-sensitive hot melt adhesive 19 is preferably applied at a position that is inside from the edge of the packaging film 13 by a pinch allowance of 39 when opened. Further, when the packaging film 13 coated with the pressure-sensitive hot melt adhesive 19 is used, the adhesive coating step 32 for packaging can be omitted.

  In the half-folding step 33, the face mask 1 is folded in a double-fold shape along a double-fold line 9 at the center in the left-right direction of the sheet body 2. In this case, even when the face mask 1 is in a wet state impregnated with a cosmetic liquid, each knob 3 is reinforced by the reinforcing film 4, so that the knob 3 is folded inward and folded in two. There is no problem of being sandwiched between the bodies 2, and the face mask 1 can be easily and reliably folded into two. In the folded state, the pair of knobs 3 are close to each other on the opposite side of the folding line 9 so that they do not overlap. In addition, when the face mask 1 is folded in half, it is desirable to fold so that the left and right cuts 5 to 8 of the sheet body 2 do not coincide.

  In the supplying step 34, the folded face mask 1, that is, the folded body 12, is sequentially supplied onto the packaging film 13 after the application of the pressure-sensitive hot melt adhesive 19. In this case, the bi-fold face mask 1 is supplied on the packaging film 13 at substantially equal intervals in the longitudinal direction with the bi-fold line 9 facing the substantially width direction of the packaging film 13. The folded face mask 1 fits within the width of the packaging film 13, and a seal margin 40 of a predetermined width remains on the edge side of the packaging film 13 to which the pressure-sensitive hot melt adhesive 19 is applied. It arrange | positions in the middle of the width direction so that the folding margin 41 of predetermined width may remain on the edge side.

  In the folding step 35, the packaging film 13 is formed so that, when passing through the folding means, a folding line 18 in the longitudinal direction substantially perpendicular to the folding line 9 is formed in the vicinity of the end of the folded body 12 of the face mask 1. Folding allowance 41 minutes on one end side is folded inward and folded on the two-fold body 12.

  In the wrapping step 36, the folded-up face mask 1 and the packaging film 13 are folded in two so that the folded portion 13c of the packaging film 13 folded on the face mask 1 in the folding step 35 is inside. It winds in one direction along the fold lines 14 and 15 at a plurality of positions in nine directions and wraps in a flat shape. In this embodiment, since the half-folded face mask 1 is folded in a three-fold manner at two folding lines 14 and 15 in the direction of the two-fold line 9, the wrapping step 36 includes the first folding step 42, The second folding step 43 is configured.

  In the first folding step 42, when the first folding means passes, the wrapping portion 13c of the wrapping film 13 is sandwiched between the intermediate portion 12a and the inner portion 12b of the foldable body 12, and the wrapping film 13 One end side of the face mask 1 is folded inward along the fold line 14. In the second folding step 43, the outer end portion of the outer portion 12c of the bi-fold body 12 overlaps the packaging film 13 on the inner portion 12b folded in the first folding step 42, and this outer end portion The other end side of the packaging film 13 and the two-folded body 12 is folded inward along the fold line 15 so that the pressure-sensitive hot melt adhesive 19 side of the packaging film 13 overlaps from above on the outer side.

  The sealing step 37 is a vertical sealing step 44 in which the other end of the packaging film 13 is pressure-sensitively bonded to the inner packaging film 13 with a pressure-sensitive hot melt adhesive 19, and the packaging films 13 are thermally welded to each other in both longitudinal directions. And a transverse sealing step 45 for fusing, and after folding in three, the packaging film 13 is sealed with the longitudinal sealing portion 16 and the transverse sealing portion 17 and sequentially melted between the transverse sealing portions 17 to form a packaging comprising the packaging film 13. One face mask package 11 in which the face mask 1 is sealed with the bag 10 is taken out through a face mask package take-out step 38. The fusing process may be separated from the horizontal sealing process 45 and provided after the horizontal sealing process 45.

  In this way, while folding the face mask 1 and the packaging film 13 together, the face mask 1 is wrapped and flattened by the packaging film 13, and the packaging film 13 is sealed by the vertical seal portion 16 and the horizontal seal portion 17. By constituting the sealed packaging bag 10, the face mask 1 can be individually packaged. In the first folding step 42 and the second folding step 43, the two-folded face mask 1 is further folded into a three-fold shape, but the face mask 1 and the outer packaging film 13 are folded together. Despite being there, the knob 3 is not folded inward. In particular, by reinforcing the knob 3 with the reinforcing film 4, the shape retention of the knob 3 is improved. For this reason, coupled with the presence of the packaging film 13 on the outside of the face mask 1, it is possible to reliably prevent the knob 3 from being folded. Accordingly, it is possible to easily accelerate the work.

  Moreover, the inner and outer end portions of the face mask 1 are opposed to other portions via the packaging film 13, and are not in direct contact with other portions of the face mask 1. Accordingly, the packaging film 13 constituting the packaging bag 10 can be used as a kind of inclusion, and the face mask 1 is confirmed to be separated from the inside and outside of the face mask 1 when opened, even though the face mask 1 is impregnated with a cosmetic liquid. The face mask 1 in a folded state can be easily expanded by grasping the end portion.

  FIG. 13 illustrates a second embodiment of the present invention. As shown in FIGS. 13A and 13B, the face mask 1 has tabs 3 formed on both sides of the sheet body 2 in the oblique direction, and the sheet body is formed by a left and right fold line 9 in the middle in the vertical direction. 2 is folded in two.

  As described above, the knob 3 may be provided at an arbitrary position as long as it is the outer periphery of the sheet body 2. Moreover, when the knob | pick part 3 is a pair, it is desirable to arrange | position at the position on the substantially opposite side, respectively. However, when the bifold body 12 is folded in a trifold shape, the fold lines 14 and 15 are located on the outer side or the inner side between the two fold lines 14 and 15. It is desirable to deviate from 3. Of course, the folding lines 14 and 15 may be folded so as to pass through the knob 3.

  FIG. 14 illustrates a third embodiment of the present invention. The reinforcing film 4 may be provided on the entire surface of the knob 3, but may be provided on a part of the knob 3 as shown in FIGS. 14 (A) to (C). In that case, in order to make it easy to find the edge of the knob 3, it is desirable to match the protruding edges of the reinforcing film 4 and the knob 3. In addition, a paint or other coating material may be applied to the knob portion 3 to form a reinforcing material.

  15 and 16 illustrate a fourth embodiment of the present invention. This face mask package 11 is obtained by folding the face mask 1 in an unfolded state together with the packaging film 13 in a three-fold or four-fold manner in one direction. The packaging method is the same as in FIGS. In this case, the length of the face mask package 11 is increased. However, when the packaging bag 10 is opened, the face mask 1 can be opened by opening from the side of the vertical seal portion 16 and then expanding while peeling off the horizontal seal portion 17 in sequence. Can be expanded into an unfolded shape.

  As mentioned above, although each Example of this invention was explained in full detail, this invention is not limited to each Example. For example, the pack sheet body 2 may be used as a pack for the knee and other parts in addition to the face mask 1 for the face. The sheet body 2 may be a sheet, non-woven fabric or other sheet-like material having excellent water absorption. Therefore, a composite sheet in which a plurality of sheets are stacked may be used.

  The reinforcing material of the knob part 3 is constituted by the reinforcing film 4, and the coating part or other material has a non-water-absorbing coating material or water repellency at the knob part scheduled cutting part 27 of the raw sheet material 20. You may form by apply | coating a coating agent. In addition, it is desirable that the knob portion 3 protrudes outward from the sheet body 2, but the entire periphery of the outer peripheral edge portion of the sheet body 2 or a part on both sides in the diagonal direction is set as the knob portion 3, and the knob is removed. The part 3 may be reinforced with a reinforcing material.

  The outer edge of the outer side of the packaging film 13 may substantially coincide with the edge of the packaging bag 10 in the width direction. When the bifold body 12 of the face mask 1 is folded, it is desirable to fold it in multiple folds of three or more folds, for example, the number of folds is four. In the case of the face mask package 11 in which the face mask 1 is hermetically packaged with the packaging bag 10 made of the packaging film 13, the knob 3 need not be reinforced with a reinforcing material. The pack sheet may be strip-shaped. The face mask 1 and the packing sheet tab 3 can be omitted. In addition, the present invention can also be applied to a therapeutic sheet in which the sheet 2 is impregnated with a chemical solution.
