BEST MODE FOR CARRYING OUT THE INVENTION

Next, embodiments of the present invention will be described in detail below with reference to the drawings.

(First shape example)

FIG. 1 shows a pocket type mask 1. The mask 1 includes a main body portion 2 that covers the mouthpiece and the nasal cavity, and a locking portion 3 for locking the main body portion 2 to the body. The main body 2 includes a left portion 2L and a right portion 2R that are symmetric with respect to the center line in the width direction. Both the portions 2L and 2R are formed of a flat material and are joined at the edge 4 on the center side in the width direction. Further, the joint portion 4 has a curved shape in which an intermediate portion bulges outward from both upper and lower sides.

On the other hand, the locking portion 3 is an annular flat member having an opening 5 for hanging on the ear, and is joined to the left and right side edges 2e, 2e of the main body portion 2. [0021] The main body 2 and the locking portion 3 are flat when the left portion 2L and the right portion 2R are overlapped. On the other hand, the main body 2 is cup-shaped in a use state (shown state) in which the space between the left portion 2L and the right portion 2R is widened. In this state, if the wearer's mouth and nasal cavity are covered, the space around the mouth and nasal cavity can be left and covered.

[0022] (Second shape example)

In the first shape example, the main body 2 and the locking portion 3 are formed as separate members and joined together. However, as shown in FIG. It can be formed as a single member.

[0023] (Third shape example)

Although not shown, in the pocket type form, it is not necessary to form the joining line along the vertical direction. For example, it can be formed along the width direction.

[0024] (Fourth shape example)

3 and 4 show a flat type mask 11. This mask 11 has a main body 2 that covers the mouthpiece and the nasal cavity, and a locking portion 3 for locking the main body 2 to the body. I have. The main body part 2 has a plurality of pleats 6 (an heel formed by zigzag folding) along the width direction, and rubber hooks for hooking ears as locking parts 3 are attached to both sides of the pleats 6 in an annular shape. It is. The number of pleats is preferably 2 to 3.

[0025] In this example, when the upper end and the lower end are pulled apart from each other in the intermediate portion in the width direction of the main body 11, the pleat 6 expands so that the central portion bulges outward, and the cup shape as a whole is formed. Deformed to Therefore, as shown in FIG. 5, if a force S is applied to cover the mouth or nasal cavity of the wearer in this state, the space can be covered around the mouth or nasal cavity.

[0026] As the shape of the main body 2, an appropriate shape such as an ellipse or a rhombus can be employed in addition to the rectangular shape shown in the figure.

[0027] (Fifth shape example)

As shown in FIG. 6, the fifth shape example is obtained by omitting the pleats from the fourth shape example having the pleats 6. Such a simple form can also be adopted.

[0028] (Sixth shape example)

The locking portion 3 of the form shown in FIGS. 1 to 4 is a type that hooks the annular member to the ear. In addition, a type in which both side portions of the main body portion are connected by a belt-like member, and the belt-like member is hung around the head portion or the neck portion and locked (not shown) can also be adopted. This type of locking portion is disclosed, for example, in JP-A-9 313631.

[0029] (Main body structure and materials)

The main body 2 may have a single-layer structure, but preferably has a structure having a plurality of layer forces. For example, as shown in FIG. 2, it has a two-layer structure having an outer layer 2A and an inner layer 2B, or has an outer layer 2A, an inner layer 2B, and an intermediate layer 2C interposed between them as shown in FIGS. Or a three-layer structure. In particular, as shown in FIG. 2, the main body 2 and the locking portion 3 are integrally formed as a single member by the outer layer 2A (which may be the inner layer), and the inner layer is formed on the inner surface of the corresponding portion of the main body. By laminating 2B, the main body 2 is made into a two-layer structure.

[0030] In the case of a plurality of layers, at least one layer, for example, an inner layer 2B in a two-layer structure as shown in FIG. 2, or an intermediate layer 2C force in a three-layer structure as shown in FIGS. It is preferable that the functional layer has a fragrance function, virus' allergen inactivation function, antibacterial function, shape retention function, etc.

[0031] It is also preferable that such a functional layer is detachably attached to the main body 2. For example, as shown in FIG. 6, when the intermediate layer 2C in the three-layer structure is a functional layer, the functional layer may be connected via the edge of the main body 2 (or an opening provided in the outer layer 2A or the inner layer 2B). By making 2C freely accessible, the functional layer can be made detachable. Such a layer structure composed of a plurality of layers can also be employed in the locking portion.

[0032] Here, the feature of the present invention is that, regardless of whether the main body portion is a single layer or a multilayer structure, at least a layer constituting a surface in contact with the face of the main body portion is a nonwoven fabric, and It is characterized in that a smoothing agent is contained in all or a part of the surface of the main body that comes into contact with the face. That is, the present invention is characterized in that a smoothing agent is contained by impregnating or applying a smoothing agent to all or a part of the non-woven fabric layer constituting the face that comes into contact with the face. To do. It is easy to manufacture in the form of a single-layer nonwoven fabric structure with a smoothing agent applied to the entire contact surface, but in a form in which the smoothing agent is contained only in a portion that easily rubs against the skin. May be. [0033] Here, the portion that is easily rubbed with the skin is a portion that requires close contact with the skin in order to prevent entry of dust, pollen, etc., as shown in FIG. 7 as an example of a rectangular main body. Peripheral part A of the surface 20 that comes into contact with the skin of a certain main body part, as well as the surface that comes into contact with the skin of the main body part that is easy to contact with the nasal head as shown in the example of the rectangular main body part in FIG. In this case, there is a portion B in the vicinity of the center line extending in the vertical direction at the center in the left-right direction. Therefore, a form in which a smoothing agent is applied only to the peripheral edge A or the vicinity of the center line B may be used. Of course, a smoothing agent may be applied to both portions A and B. In addition, the peripheral part A means a range in which the distance L1 from the peripheral edge E of the main body part is approximately 1 to 5 cm, preferably about 2 to 3 cm, and the vicinity of the center line B is a distance from the center line C. L2 is generally in the range of about 1 to 3 cm, preferably about 1.5 to 2 cm, toward the left and right (in the direction of the locking part). Of course, although not shown, of course, even when the body-shaped main body shown in FIGS. 1 and 2 is adopted, a smoothing agent is applied only to the periphery of the main body and the vicinity of the center line. Can do.

[0034] Here, as the smoothing agent, a known smoothing agent used for sanitary thin paper such as tissue paper can be used. Specific examples include wax, MPC polymer, glycerin, diglycerin, polyethylene glycol having an average molecular weight of 200 to less than 1,000, sorbitol, propylene glycol, 1,3-butylene glycol, glycine betaine, pyrrolidone carboxylic acid, pyrrolidone carboxylic acid. Examples include one or more of acid salts, maltitol, sodium lactate and the like. Preferred are wax, MPC polymer, and glycerin.

[0035] In order to manufacture a mask in a form in which a smoothing agent is contained on the surface of the main body, a smoothing agent is applied or impregnated in advance on the non-woven fabric before being cut into the size of the main body. Good. For the application of the smoothing agent to the nonwoven fabric, a known method such as spraying or roll transfer can be used. If in-line application is adopted as the form of the smoothing agent applied to the non-woven fabric, it can be appropriately applied to the required place, and it is not necessary to adjust the cut pitch.

[0036] As described above, when a smoothing agent is applied, it is desirable to use a hydrophilic material as the nonwoven fabric constituting the layer in contact with the face. It has a high affinity with a smoothing agent and an excellent holding power of the smoothing agent, and it is also difficult to dry and has the ability to further reduce irritation to the skin. Examples of hydrophilic non-woven fabrics include those using hydrophilic fibers, rayon fibers Examples thereof include those using fibers, those using cotton, pulp mixed nonwoven fabrics, and the like.

[0037] The coating amount of the smoothing agent is 1 to 15 gsm, preferably 3 to 8 gsm, particularly preferably 4 to 6 gsm. If it is less than lgsm, the moisturizing effect is small, and if it exceeds 15 gsm, stickiness is produced and it becomes rather uncomfortable.

[0038] Here, on the other hand, since the skin irritation is reduced, it is desirable that a part or all of the layer constituting the surface of the main body contacting the face is made of a melt blown nonwoven fabric. In addition, it is easy to manufacture, and it may be slidable with the force of the skin, which is a single layer structure in which all the layers are made of a melt blown nonwoven fabric, or only a part may be made of a melt blown nonwoven fabric. Here, the portion that easily rubs with the skin is the portion B that easily comes into contact with the peripheral edge portion A and the nose of the mask main body as described above.

[0039] The melt-blown nonwoven fabric can be produced by a conventionally known method. For example, a raw material polymer such as a crystalline propylene-based polymer is melt-extruded, and fibers spun from a melt-blow spinneret are made ultrafine by high-temperature and high-speed gas. It can be blow-spun as a fiber stream, made into an ultrafine fiber web on a collection device such as a wire mesh or a belt, and manufactured through an adhesion process. The average fiber diameter of the fibers forming the melt blown nonwoven fabric is not limited, but is usually about 1 to 30 / ζ πι, preferably about 2 to about LO m.

[0040] The basis weight of the nonwoven fabric constituting the main body is usually 15 to 70 gZm ² , preferably 20 to 60 g / m ² . If it is less than 15 g / m ^2, it is difficult to ensure the required strength, and if it exceeds 70 g / m ² , the texture is lowered, which is desirable! /.

[0041] On the other hand, when the main body portion has a two-layer structure, the layers other than the layer constituting the surface in contact with the face may be a nonwoven fabric other than the melt blown nonwoven fabric. Therefore, for example, a non-woven laminate obtained by laminating two or more layers of a spunbond nonwoven fabric (S) layer formed with a web by the spunbond method and a meltblown nonwoven fabric layer (M) formed with a web by the meltblown method is masked. It can be used as a material for the main body. In this way, it is possible to form a main body portion having a laminated structure in which a part of the surface in contact with the face is a melt blown nonwoven fabric.

[0042] That is, when obtaining a laminate, for example, fibers formed by a melt blown method are directly deposited on a part (or all of them) of a spunbonded nonwoven fabric to melt the laminate. After forming a blown nonwoven fabric, heat-spun the spunbond nonwoven fabric and the meltblown nonwoven fabric, overlaying the spunbond nonwoven fabric and the meltblown nonwoven fabric, and fusing both nonwoven fabrics with heated caloric pressure, the spunbond nonwoven fabric and the meltblown nonwoven fabric If a method of bonding with an adhesive such as a hot-melt adhesive or a solvent-based adhesive is adopted, it becomes easy to make a part of the surface in contact with the face a melt-blown nonwoven fabric.

[0043] Here, a method of directly forming a meltblown nonwoven fabric on a spunbonded nonwoven fabric is obtained by a meltblown method in which a melt of thermoplastic resin is sprayed on a part or all of the surface of the spunbond nonwoven fabric to deposit fibers. It can be carried out. At this time, with respect to the spunbond nonwoven fabric, the surface opposite to the surface on which the melt is sprayed is set to a negative pressure, and the fibers formed by the melt blown method are sprayed and deposited, and at the same time, the spunbond fabric is not spun. The woven fabric and the meltblown nonwoven fabric are integrated to obtain a flexible nonwoven fabric laminate having a spunbond nonwoven fabric layer and a meltblown nonwoven fabric layer. If the two nonwoven fabrics are not sufficiently integrated, they can be sufficiently integrated with a heat and pressure embossing roll or the like.

[0044] As a method of fusing the spunbond nonwoven fabric and the meltblown nonwoven fabric by heat fusion, a method of heat fusing the entire contact surface between the spunbond nonwoven fabric and the meltblown nonwoven fabric, There is a method of heat-sealing part of the contact surface.

[0045] (Material for locking part)

The material of the locking part 3 can be selected with the same material strength as that of the main part 2. However, it is preferable to select a material that is rich in elasticity and elasticity and has little irritation to the skin.

[0046] For example, in the case of the pocket-type mask 1, a laminated nonwoven fabric obtained by attaching a nonwoven fabric to both the front and back sides of the elastic stretch film, and performing a stretch improvement process such as a needle stick process as necessary, In addition to a stretchable nonwoven fabric obtained by heat-treating a web made of heat-crimpable composite fiber, a pair of nonwoven fabrics are bonded together, and a stretchable material such as thread rubber is sandwiched between the nonwoven fabrics. A suitable non-woven fabric can be used.

[0047] Further, for example, in the case of the flat mask 11, in addition to selecting the same material as in the case of the pocket mask 1, flat rubber, round rubber or the like can be used.

[0048] Further, a material obtained by combining these materials and the materials described in the section of the main body 2 by lamination or the like. Can also be used as the locking portion 3.

[0049] Of course, as long as the stretchability for locking is not hindered, it is possible to adopt a form in which the surface contacting the face of the locking portion is formed of a melt blown nonwoven fabric, and a smoothing agent is applied. Can be.

[0050] (Size of main unit)

The size of the main body 2 can be determined as appropriate and is not particularly limited.

In case of pocket type, length 90 ~ 150mm, width 60 ~: L can be 10mm, and in case of flat type (if you have pleat 6, unfolded pleat 6), length 80 ~ 110mm

The width can be 80 to 180 mm.

[0051] (Other)

The members and the layers can be bonded to each other by a known bonding means such as heat sealing, hot melt bonding, or ultrasonic welding.

Industrial applicability

[0052] The present invention can be applied to a wide range of uses in addition to a mask covering the nose and mouth for the purpose of blocking allergens in hay fever and the like, and preventing infection in colds and the like.
