[0008] However, for the mask of Patent Document 6, the cosmetic material applied to the face may be attached to the high water-containing gel and peeled off. Because the gel has a sticky touch, the gel is cold at the initial stage of wearing, which is easy to bring Discomfort
For the mouth mask of patent document 7, it is necessary to use a double-sided adhesive tape to fix the mask main body on the cheek surface to resist the elasticity of the resin sheet and the metal sheet, so it is necessary to use a double-sided adhesive tape with high-intensity bonding force, Unavoidable strong discomfort on the jointed skin side of the double-sided adhesive tape, when the mask is used continuously for a long time, it is easy to feel pressure
In addition, it is difficult to select a double-sided adhesive tape that has high bonding strength and does not cause itching and rashes on the skin.

no. 1 approach

[0056] Figure 1 ~ Figure 3 One embodiment of the mask of this invention is shown. Figure 1 ~ Figure 3 The mask 1 of the present embodiment shown has: mask main body 2, as image 3 Shown is used to cover the face 21 (for example, the periphery of the mouth and nostrils) of the face 20 of the user;

[0057] Mask 1 is called a disposable so-called "pleated type", such as figure 1 As shown, a pleat 7 is provided near the center of the inner surface 6 of the mask 1 .

[0058] In this pleat part 7, a plurality of pleat crease parts 7a-7d which are folded with a predetermined width in the up-down direction of the mask main body 2 are formed in the width direction.

[0059] The creases 7a-7d are formed by folding the mask main body 2. When the mask main body 2 is opened up and down to unfold the folds 7, the mask main body 2 forms a mountain-shaped three-dimensional shape bulging outward.

[0060] The mask main body 2 has a quadrangular planar shape and is a laminate formed by o...

[0118] Figure 5 (a)-(d) is a figure for demonstrating one Embodiment of the manufacturing method of the mask of this invention.

[0119] In this embodiment, when the hot-melt material 10 is coated on the inner surface 6 of the mask 1 with the hot-melt spray gun 30, in the final process of coating, the function of the hot-melt spray gun 30 for spraying the hot-melt material 10 is closed. After the switch is turned off, the nozzle tip 30a of the hot melt spray gun 30 is in contact with the inner surface 6 of the mask 1 near the coating end of the hot melt material 10 .

[0120] Such as Figure 5 As shown in the front view observed from the side of the mask of (a), the hot-melt material 10 after heating and melting is applied to the inner surface 6 of the mask main body 2, and in the final process of coating using the hot-melt spray gun 30 , at position A, close the switch of the hot melt spray gun 30 to eject the hot melt material 10 . At this time, if Figure 5 As shown in...

[0124] Figure 6 ~ Figure 8 Another embodiment of the mask of the present invention is shown. In addition, the same code|symbol is attached|subjected to the part common to the said 1st Embodiment, and detailed description is abbreviate|omitted.

[0125] Such as Figure 6 As shown, for the mouth mask 1 of the present embodiment, near the upper end 4a of the peripheral edge 4, two upper end side thick parts 11, 11 and two upper end side thick parts 11 and 11 that are attached to the both sides of the nose 22 are provided near the upper end 4a of the periphery 4. The constricted part 12 between 11 and 11 is provided in a linear shape on the side opposite to the constricted part 12 of the upper thick part 11 and 11, and the upper thin parts 14 and 14 are respectively directed toward the side ends 4c and 4d.

[0126] These upper end side thick parts 11, 11, narrowed part 12 and upper end side thin parts 14, 14 form the upper end side thick part 11 and upper end side thin part 14 fr...

Abstract

Provided are: an inexpensive mask and a method for manufacturing the same, the mask itself having good fit and sealing to the face, being unlikely to fog glasses, and, having good adhesion to the face, being unlikely to be vertically displaced, tackiness not being so strong such that pain or other discomfort is experienced when the mask is removed, the elimination of release paper also being possible, etc., and in particular, the mask having good folding workability; and a mask and a method for manufacturing the same in which stringiness can be minimized when a hot-melt material is applied, and reduction in processability and product appearance can be minimized. This mask (1) is characterized by being provided with a hot-melt material (10) that is caused to adhere to a nonwoven cloth around the peripheral edge (4) of the mask inner surface (6), the hot-melt material (10) being in contact with the face (21) when the mask (1) is mounted on the face (21), and the A hardness of the hot-melt material (10) being less than 50. Also, the hot-melt material (10) is characterized by containing a thermoplastic elastomer, and by having a melt viscosity of 180,000 mPa*s or less at 190 DEG C.

Description

technical field [0001] The invention relates to a mask and a manufacturing method thereof. Background technique [0002] In the past, a kind of disposable mouth mask has been proposed, in terms of its contact portion with the nose, the upper end of the mouth mask main body is provided with a resin sheet or a metal sheet such as polyethylene that is used to keep the upper end crimped with the nose (patent document 1 ). The resin sheet and the metal sheet are also called nose fitting parts, and the disposable mask provided with the nose fitting parts is used as a commercial product. [0003] In addition, it has also been proposed to attach foamed plastic to the nonwoven fabric of the mask with an adhesive as an anti-fog measure for glasses at the contact portion between the mask and the nose (Patent Documents 2 to 5). The foamed plastic is also called a nose pad. The pad material that prevents breath leakage is attached and bonded to the non-woven mask to prevent the breath ...
