Description

  The present invention relates to a mask, and more particularly to a mask with high bulge shape stability when worn and excellent in feeling of use.

  2. Description of the Related Art Conventionally, a simple dust mask is known in which a pleated fold is provided on a mask body formed by molding so that the mask body can be folded, and a locking portion that locks in a folded state is provided (for example, Patent Document 1). reference.).

  In addition, a mask material having a predetermined width is provided with a plurality of folds (pleats) on a mask material, cut along a required length, and welded along the cutting lines at both ends thereof to form a mask body. Folded equally to the left and right, forming a joint line diagonally between the vertical center line and the upper edge to provide a triangular piece, a substantially V-shaped part is formed at the center of the upper edge of the mask body when worn It is also known that the adhesiveness from the base of the nose to the cheek is improved (see, for example, Patent Document 2).

  In addition, a mask in which a mask material having a predetermined width is provided with a plurality of folds (pleats), cut to a required length, and welded along cutting lines at both ends thereof to constitute a mask body. There is also known one in which a holder for keeping the main body bulging is fixed to the inside of the mask main body (see, for example, Patent Document 3).

Further, as shown in FIG. 7, the mask material 22 is bent into an M-shaped cross section, both ends are cut into a C-shape, and an adhesive portion 23 is formed along the cutting line to form a mask body 21, and the mask There is also known a mask 20 in which both ends of a mounting elastic string 24 are fixed between both ends of a main body 21.

  However, since the mask body of the configuration disclosed in Patent Document 1 is formed by molding the mask body, it has high shape retention so that it needs to be locked in a folded state. Although the swollen shape can be stably maintained, there is a problem that it is bulky even in a folded state.

  In addition, the mask disclosed in Patent Document 2 is not bulky because it is folded in two by folding the sheet-shaped mask material with both ends welded, but the folds are pushed out when worn. Even if a bulge is formed, the retention of the bulge shape is small, and the lips come into contact with the mask front during wearing, making it difficult to breathe and converse, lipsticks attached, and the mask front to the nose and mouth. There is a problem that there is a risk of pressure, and there is also a problem that the beauty when worn is not good.

  Further, the mask having the configuration disclosed in Patent Document 3 can hold the bulge shape to some extent by the holder, but there is a problem that the cost is high because the holder is required and an assembly process of the holder is also required. In addition, there is a problem that unless the holder is enlarged, a desired bulge shape that can form a required space around the mouth and nose cannot be maintained.

  Further, the mask 20 having the configuration as disclosed in FIG. 7 has the same problem as the mask disclosed in the above-mentioned Patent Document 2.

  In view of the above-mentioned conventional problems, the present invention provides a mask that can stably hold an appropriate bulge shape with a simple and low-cost configuration, is easy to breathe and converse while wearing, and has an excellent aesthetic appearance. This is the issue.

  The mask of the present invention forms a pair of laterally bent ridge lines and a valley fold line between them on the mask material, bends them into an M-shaped cross section, cuts both ends into a H-shape, and adheres along the cut lines. And a pair of vertically folded ridge lines that intersect the pair of horizontally folded ridge lines substantially vertically and a Y-shaped folded ridge line extending from both ends thereof to the side edge of the mask material, respectively, at the center. A valley fold line is formed.

  The mask material can be any material such as non-woven fabric, cloth, paper, soft plastic sheet, etc. It is not limited to a single sheet, but multiple sheets of the same or different materials can be stacked or a filter interposed. You may do it. For example, a laminate of 3 to 5 layers of nonwoven fabric of polyester fibers is suitable.

  According to this configuration, when the center part of the mask is pushed forward during wearing, a rectangular frame part surrounded by the center part of the pair of horizontally folded ridge lines and the pair of vertically folded ridge lines is formed, and the four corner parts thereof are vertically A bulge shape supported at both ends of a pair of Y-folded ridgelines and a pair of laterally-folded ridgelines that open in a V shape on the left and right sides can be formed, and an appropriate bulge shape can be stabilized around the mouth and nose. The mask front can squeeze your nose and mouth while wearing, there is no risk of breathing and talking with the lips coming into contact with the mask front, and lipstick. In addition, since it is not necessary to attach a holder only by forming a folding ridge line and a valley fold line, it can be configured easily and at low cost.

  In addition, if a package is folded in a M-shaped cross section at the center at a pair of vertically folded ridge lines and a Y-shaped folded ridge line and a valley fold line between them, it can be formed into a flat folded package and distributed and conveyed. Sometimes it is not bulky, it is easy to handle and transport costs can be reduced, and when it is pulled to open both sides with adhesive part, the center part of the horizontal folding ridge line is separated as the pair of vertical folding ridge lines separate Rises to form a rectangular frame portion, and the bulging shape is smoothly formed, so that a mask that is easy to use can be obtained.

  In addition, on one mask material surface between one side-folded ridgeline and the side edge that is continuous with the one side, the vicinity of the intersection of the cutting line and the side-folding ridgeline and the position spaced from the cutting line on the side edge When forming the valley fold line to connect, even if each part dimension such as the width dimension of the mask and the height dimension of the bulge part is arbitrarily set according to the race, age, etc. of the wearer, both sides of one mask material surface Is folded at a valley fold line, and the other mask material surface is overlapped in a flat state on it, so that it can be easily folded into a package that looks almost completely flat.

  According to the present invention, at the time of wearing, a rectangular frame part surrounded by a bent ridge line is formed, and the four corners thereof are supported by a Y-shaped or V-shaped bent ridge line, and are suitable around the mouth and nose. Since the bulge shape is held stably, there is no risk that the mask front will press on the nose or mouth while wearing, the lips will touch the mask front, making it difficult to breathe or converse, and lipstick Moreover, since the aesthetic appearance at the time of wearing is also excellent, and it is only necessary to form a bent ridgeline, it is possible to obtain a great effect that it can be configured easily and at low cost.

  Hereinafter, an embodiment of the mask of the present invention will be described with reference to FIGS.

A valley fold line 7 is formed, and the transverse fold ridge line 6 and the valley fold line 7 are folded into a cross-sectional M shape as shown in FIG. 4, and in this state, an appropriate length L and an appropriate inclination angle α are formed. The bonding margin 9 is formed along the cutting line 8, and the bonding margin 9 is bonded integrally by the bonding portion 3 bonded by thermal welding. The bonding portion 3 may be bonded with an adhesive or the like, but it is preferable that the bonding portion 3 is composed of a heat-welded portion because of high adhesion and productivity.

  And in the center part of the unfolded state of the mask 1 shown in FIG. 2, a pair of longitudinally bent ridgelines 10 and 10 that cross the pair of horizontally folded ridgelines 6 and 6 substantially perpendicularly are formed at an appropriate interval 2S. A Y-shaped folded ridge line 11 extending from both ends to the side edge of the mask material 2 is formed, and a valley fold line 12 is formed between the pair of vertical folded ridge lines 10 and 10 and at the center of the Y-shaped folded ridge line 11. The mask 1 is configured to be foldable in a cross-sectional M shape in the lateral direction by the pair of vertically bent ridge lines 10 and 10 and the Y-shaped bent ridge line 11 and the valley fold line 12. 13 is a valley fold line formed so as to connect both ends of the vertically folded ridge line 10 and the end of the valley fold line 7, when the vertically folded ridge line 10 is raised from the state of FIG. 4 as shown in FIG. The mask 1 is folded when folded in the transverse direction into an M-shaped cross section.

  In the wearing state of the mask 1, as shown in FIG. 1, a rectangular frame portion 14 is formed by the center portion of the pair of horizontally bent ridge lines 6 and 6 and the pair of vertically bent ridge lines 7 and 7, and the four corner portions thereof. Is supported at both ends of the upper and lower Y-shaped bent ridgelines 11 and the pair of laterally bent ridgelines 6 that open to the left and right V-shapes, and a stable bulge shape 15 having a square dome shape is formed. In addition, when the mask 1 is folded, the mask 1 is folded in a cross-sectional M shape in the lateral direction from the wearing state of FIG. 1 with a pair of vertically folded ridge lines 10 and 10 and a Y-shaped folded ridge line 11 and a valley fold line 12. Then, after the state shown in FIG. 5, as shown in FIG. 6, the package is folded into a flat shape.

  Further, in order to fold the mask 1 in the lateral direction so that it is folded into a flat shape as shown in FIG. 6, as shown in FIGS. 2 and 4, the length dimension L, the width dimension W, the depth of the valley fold portion Depending on the dimension D, S, and the inclination angle α of the C-shaped cutting line 8, etc., one mask material surface 2A between one side-folded ridgeline 6 and the side edge 2a continuous on one side thereof A valley fold line 16 is formed that connects the vicinity of the intersection of the cutting line 8 and the lateral folding ridge line 6 and a position 17 separated from the cutting line 8 on the side edge 2a.

  The dimensions of each part of the mask 1 are appropriately set according to the race of the wearer and the age group. Moreover, in those dimensional relationships, W and D naturally satisfy W> D. D and S can be arbitrarily set in the range of D / S = 0.5 to 1.5, but it is preferable that they are substantially the same. L, W, and α are preferably set such that L ≧ 2W and 45 ° ≦ α <90 °, and the inclination angle β of the valley fold line 16 is α <β <90 °.

  According to the embodiment described above, when the center portion of the mask 1 is pushed forward during wearing, the rectangular frame portion 14 surrounded by the center portion of the pair of horizontally bent ridge lines 6 and the pair of vertically bent ridge lines 10 is formed. At the same time, a square dome-shaped bulge shape 15 is formed in which the four corners are supported at both ends of a pair of upper and lower Y-shaped bent ridgelines 11 and a pair of laterally bent ridgelines 6 that open in a V shape on the left and right. The proper bulge shape 15 is stably held around the wearer's mouth and nose, and the mask front presses the nose and mouth during wearing, and the lips touch the mask front and makes breathing and conversation difficult. There is no risk of becoming lipsticks or lipsticks, and the aesthetics when worn are also excellent.

  In addition, as a package at the time of distribution of the mask 1, it is assumed that the package is folded in an M-shaped cross section at the center by a pair of vertically folded ridge lines 10 and a Y-shaped folded ridge line 11 and a valley fold line 12 therebetween.
