Hereinafter, the mask of the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.
<First Embodiment>
FIG. 1 is a plan view and a sectional view showing a first embodiment of the mask of the present invention. Hereinafter, the upper side in FIG. 1A is referred to as “upper” and the lower side is referred to as “lower”.

  As shown in FIG. 1A, the mask 10 includes a mask main body 11 and a string (fixing means) 12 for fixing the mask main body 11 to the face.

Hereinafter, the configuration of the mask 10 will be sequentially described.
The mask body 11 is made of a sheet material having a size enough to cover the mouth and nose of the mask user.

Examples of the sheet material constituting the mask main body 11 include a fabric such as a woven fabric, a non-woven fabric, and a knitted fabric, and a film or paper having air permeability. Of these, woven fabric or non-woven fabric is preferably used.
Specific examples of the woven fabric include gauze and the like.

  Non-woven fabric refers to clothing materials, packaging materials, and the like, in which fibers are arranged in an indefinite direction, entangled, welded, and bonded to each other without going through a woven process.

  Non-woven fabrics are entangled with fibers, and thus have no vertical and horizontal orientations, and are not easily frayed.

  Such non-woven fabric production methods include conventional non-woven fabric production methods, for example, a suction heat bond method for heat-treating a web obtained using a card machine, a mechanically entangled needle punch method, and a hydroentangled span. It can be produced by a lace method, a spunbond method, a meltblown method, an SMS method (bonding of a spunbond nonwoven fabric and a meltblown nonwoven fabric) or the like. Of these, the spunbond method is preferable because of its good productivity and low cost.

  Examples of the fibers constituting the mask body 11 include natural fibers such as wool, silk, linen and cotton, recycled fibers such as rayon and acetate, synthetic materials such as polyester, polyamide, vinylon, polyacrylonitrile, polyolefin and spandex. It can be composed of various fibers such as fibers. More preferred are polyolefins, polyesters and polyamides.

  Examples of the polyolefin include polyethylene, polypropylene, polybutene-1, polypentene-1, and random or block copolymers thereof, or non-methacrylic acid, acrylic acid, maleic acid, fumaric acid, crotonic acid, itaconic acid and the like. Examples thereof include polyolefin polymers obtained by copolymerizing at least one selected from saturated carboxylic acids and derivatives such as esters and acid anhydrides thereof. Furthermore, the graft copolymer which grafted at least 1 sort (s) of the said unsaturated carboxylic acid or its derivative (s) to the said polyolefin-type polymer can be mentioned.

  Examples of the polyester include polyethylene terephthalate and polybutylene terephthalate. Examples of the polyamide include nylon-6 and nylon-66.

  The strings (fixing means) 12 are attached to both ends of the mask main body 11 in the left-right direction.

  The string 12 is used to fix the mask body 11 to the face by putting it on an annular ear.

  Note that the fixing means may be, for example, an annular band or rubber string that is hooked to the ear, a band or string that is clung to the head, or a vine-shaped eyeglass that is applied to the upper part of the ear, instead of the string 12 shown in FIG. It can consist of things.

  The mask 10 of the present invention is provided along the vertical direction of the mask main body 11 and is characterized in that a plurality of shape holding members 13 are provided to partially deform the shape of the mask main body 11 and hold the state. Have. Thereby, the mask 10 which can deform | transform the mask main body 11 into a desired shape according to the shape of a person's face and the intended purpose of the mask 10 can be provided.

  In the present embodiment, as shown in FIG. 1, three shape holding members 13 are arranged along the vertical direction at both the left and right ends and the center of the rectangular mask body 11.

  Here, the up-down direction and the left-right direction of the mask body 11 refer to directions in a state where the mask 10 is mounted on the face, respectively.

  By providing the shape holding members 13 at the left and right ends of the mask main body 11, the shapes of the both ends of the mask main body 11 can be partially deformed to hold the state. As a result, the direction of the air flow due to breathing can be controlled in the left-right direction to prevent fogging and breathlessness of the glasses.

  Further, since the shape holding member 13 is provided at the center, a gap is formed between the mask main body 11 and the mouth, so that lipstick and the like can be prevented from adhering to the mask main body 11.

  The shape maintaining member 13 is formed of a strip-shaped (band plate-shaped) or linear (bar-shaped) member that can be plastically deformed.

  “Plastic deformable” (plastic deformability) refers to the property of maintaining the forced deformation state even after the bending force is released after the object (shape holding member 13) is bent into an arbitrary shape. . Therefore, the shape holding member 13 made of such a plastically deformable member can deform the mask body 11 into a desired shape and maintain the state.

  As the number of the shape holding members 13 increases, the mask can be freely deformed and adjusted according to the shape and purpose of the individual face. However, if the number is too large, the adjustment work becomes complicated. The number of the shape holding members 13 is preferably about 2 to 5 because the wearability or the feeling of wearing is impaired.

  In addition, the arrangement of the shape holding member 13 is not particularly limited, and may be appropriately arranged according to the shape and purpose of the mask 10, but considering the symmetry of the shape of the face, it is arranged symmetrically. Preferably it is done.

  As a material constituting the shape holding member 13, a material mainly made of a resin material is preferable. Although depending on the composition, the resin material is excellent in flexibility and plasticity, and can change its shape relatively easily by the force of a finger and can maintain the state. Further, since the specific gravity of the resin material is small, the shape holding member 13 can be lightened, and the weight of the mask 10 can be reduced.

  Moreover, as the shape holding member 13, what extended | stretched the resin material is preferable. Thereby, since the elasticity of the resin material is lowered, the shape retaining property of the shape retaining member 13 can be improved.

  Furthermore, when the resin material is stretched, the total stretching ratio is preferably about 10 to 40 times, and preferably about 15 to 35 times. When the total draw ratio is within the above range, the resin material can be sufficiently drawn out without breaking.

  Here, as a method of stretching the resin material, methods such as rolling and tension can be cited. Among these, in the case of rolling, it is obtained by rolling and stretching the resin material. The total stretching ratio is the product of the rolling ratio and the stretching ratio. The rolling ratio is 5 to 16 times and the stretching ratio is 1 3 to 2.5 times, and the total draw ratio is 10 to 40 times.

  In addition, although it varies depending on the thickness and outer diameter of the shape holding member 13, since the resin material can be changed in shape with the force of a finger and held in that state, the constituent material of the shape holding member 13 can be maintained. It is suitable as.

  Examples of the resin material include polyolefin-based resins, polyvinyl chloride-based resins, methacrylic-based resins, and the like. Among these, materials mainly composed of polyolefin-based resins are preferable. Since the shape holding member 13 made of polyolefin resin is highly flexible, its shape can be changed relatively easily. In addition, the polyolefin resin does not generate dioxins even when incinerated and has little environmental impact.

  Examples of polyolefin resins include high density polyethylene resins, medium density polyethylene resins, low density polyethylene resins, polyethylene resins such as linear low density polyethylene resins, polypropylene resins, ethylene-propylene copolymers, ethylene-pentene- 1 copolymer, ethylene-vinyl acetate copolymer, ethylene- (meth) acrylic acid ester copolymer, ethylene-vinyl chloride copolymer, ethylene-propylene-butene copolymer, etc., among these High density polyethylene resin is preferably used.

As a polyethylene-type resin, it is preferable that the density is 0.94 g / cm < ³ > or more, and it is more preferable that it is 0.96 g / cm < ³ > or more. If the density is within the above range, shape retention after the polyethylene resin is stretched is improved.

  The weight average molecular weight of the polyethylene resin is preferably about 50,000 to 500,000, and more preferably about 200,000 to 500,000. When the weight average molecular weight is within the above range, the polyethylene resin has high shape retention after being stretched, and can be more easily molded and stretched.

  Further, the melt index (MI) of the polyethylene resin is preferably in the range of about 0.1 to 20, more preferably about 0.2 to 10. Thereby, shaping | molding of the shape holding member 13 becomes easier.

  Moreover, although high density polyethylene may be used independently, what mixed other polyolefin resin may be used.

  Specifically, what mixed other polyolefin-type resin in the ratio of 30 weight part or less with respect to 100 weight part of high-density polyethylene can be used. Examples of other polyolefin resins used in combination include a low density polyethylene resin, an ethylene-vinyl acetate copolymer, and polyvinyl acetate. Further, the high-density polyethylene resin may be cross-linked.

  In addition, the shape maintaining member 13 preferably has an average thickness in a band plate shape of about 0.05 to 1.5 mm, more preferably about 0.15 to 1.0 mm. When the shape holding member 13 is thin, the shape holding force is reduced, and the shape is likely to be restored following the mask body. When the shape holding member 13 is thick, it is difficult to form the shape holding member 13 into a desired shape.

  Moreover, as a material which comprises the shape holding member 13, a metal material may be used as a main material. Since the metal material is easily plastically deformed by being applied with a stress higher than the yield stress, by setting the dimensions (thickness, width, outer diameter, etc.) of the shape holding member 13, The shape can be changed relatively easily with the force of and adjusted so as to maintain the state.

  For this reason, the metal material constituting the shape maintaining member 13 is preferably one having a low yield stress.

  Specific examples include Cu, Ni, Fe, and alloys containing these as main components, and one or more of these can be used in combination. Since these metal materials have relatively low yield stress, depending on the shape of the shape holding member 13, the shape of the shape holding member 13 can be changed relatively easily and adjusted to hold the state. it can.

  Such a shape holding member 13 is preferably provided inside the mask body 11. Thereby, it is possible to prevent the shape maintaining member 13 from being exposed from the mask main body 11. As a result, the safety of the mask 10 can be improved.

  From the above, it is preferable that the end portion of the shape maintaining member 13 is rounded. Thereby, while the safety | security of the shape holding member 13 improves more, it can prevent more reliably that the shape holding member 13 penetrates the mask main body 11, and is exposed outside.

  In addition, the shape holding member 13 is preferably fixed to the mask body 11. Thereby, it is possible to prevent the shape holding member 13 from being displaced with respect to the mask main body 11.

  In the mask 10 of the present invention, the method for fixing the shape holding member 13 to the mask main body 11 is not particularly limited, and examples thereof include sewing, adhesion with a hot melt adhesive, ultrasonic fusion, and the like. . Among these, for the attachment of the shape holding member 13 made of a resin material to the mask body 11, a hot melt adhesive or ultrasonic fusion is applied to the mask body 11 of the shape holding member 13 made of a metal material. For attachment, sewing is preferable in that each can be firmly attached to each other.

FIG. 1B shows a cross section of the mask 10 shown in FIG. 1A taken along line A, and shows a state in which the shape holding member 13 is sewn to the mask body 11 with a thread 14.
The fiber which comprises the thread | yarn 14 is not specifically limited, What kind of thing may be sufficient.

  The hot melt adhesive is not particularly limited, and conventionally known adhesives can be used. Examples of such hot melt adhesives include, for example, an ethylene-propylene copolymer system, a propylene-1-butene copolymer system, an ethylene-1-butene copolymer system, and a homopolypropylene copolymer mainly composed of amorphous polyolefin. Hot melt adhesion such as polymer systems, olefin copolymer systems such as EVA (ethylene-vinyl acetate copolymer) system, EVOH (ethylene-vinyl alcohol copolymer) system, EEA (ethylene-ethyl acrylate copolymer) system Agents.

  Further, the hot melt adhesive may contain other low molecular weight components such as other thermoplastic resins and waxes as necessary.

  As an adhesion method, for example, a hot melt adhesive heated by using a hot melt gun, a hot melt applicator, or the like is applied to the shape holding member 13, and the application surface is brought into contact with the surface of a necessary portion of the mask body 11. A method of sticking to is suitable.

  The ultrasonic fusion may be performed at any part of the shape maintaining member 13, but the shape retaining property of the shape retaining member 13 is obtained by fusing only both end portions of the shape retaining member 13 to the mask body 11. Can be fused with almost no loss. The method of ultrasonic fusion is not particularly limited, but it is usually preferable to apply a vibration of 10 kHz or more to the fusion part.

  Such a mask body 11 preferably has an average thickness of about 0.1 to 10 mm, and more preferably about 0.5 to 5 mm. When the average thickness of the mask main body 11 is within the above range, the mask main body 11 can surely exhibit the original function of the mask such as dust proofing and can obtain air permeability that does not hinder breathing.

  Further, an additional value member that gives a specific added value to the mask may be provided in the mask body 11. Examples of the value-added member include a filtering member that filters air during breathing, and an aromatic member that emits a pleasant scent such as herbs. The added value given to the mask by the added value member is not particularly limited.

  As described above, according to the present embodiment, a plurality of shape holding members 13 that are provided along the vertical direction and partially deform the shape of the mask main body 11 and hold the state thereof are arranged. It is possible to provide a mask 10 that can be deformed according to the shape.

  In addition, since the mask 10 can arbitrarily create a passage for air, it does not cause breathing. For a person wearing glasses, the breathing through the mask 10 and the nose causes the glasses to leak. Can be prevented from clouding.

Second Embodiment
2 and 3 are plan views showing a second embodiment of the mask of the present invention. Hereinafter, the upper side in FIGS. 2 and 3 is referred to as “upper”, and the lower side is referred to as “lower”.

  Hereinafter, although the second embodiment will be described, the description will be focused on the differences from the first embodiment, and the description of the same matters will be omitted.

  In the mask 20 of this embodiment, in addition to the plurality of shape holding members 13 provided along the vertical direction described above, the mask 20 is provided along the left-right direction, and the shape of the mask body 11 is partially deformed. It is the same as that of the said 1st Embodiment except having the 2nd shape holding member 21 of the strip | belt shape (band plate shape) or linear (bar shape) which hold | maintains a state. Thereby, the mask 20 which can be deform | transformed more freely according to the shape of a person's face and the intended purpose of the mask 20 can be provided. Further, since the mask body 11 can be stably maintained in a deformed state and can be surely fitted to the face, it is ensured that the mask body 11 is displaced with respect to an external load caused by walking or exercise. Thus, the mask 20 is prevented.

  The second shape holding member 21 is connected to at least one of the plurality of shape holding members 13. Thereby, it can prevent more reliably that the mask main body 11 is twisted or wound.

  Further, the second shape holding member 21 may connect two or more shape holding members 13 to each other. Thereby, the effect of preventing the twisting and winding of the mask body 11 becomes more remarkable.

  The arrangement site of the shape holding member 21 is not particularly limited, and is appropriately arranged according to the shape and purpose of the mask 20.

  The mask 20 of the present embodiment has two second shape holding members 21 at the upper end portion and the central portion of the mask main body 11. Thereby, the second shape holding member 21 is arranged on the upper end portion (one end portion in the vertical direction) of the mask main body 11, so that the upper end portion of the mask main body 11 can be aligned with the nose (the contour of the face). And the displacement of the mask 20 can be prevented.

  In addition, a gap can be formed between the mask user's mouth and the mask body 11 by the second shape holding member 21 disposed at the center of the mask body 11, so that lipstick or the like is formed on the mask body 11. Adhesion can be prevented.

  According to such a mask 20, since the shape holding members are arranged in the left and right directions in addition to the vertical direction, the shape holding members 13 and 21 are placed when the mask body 11 covers a part of the face. It can be deformed more finely according to the unevenness of the face, particularly the unevenness of the nose and mouth, and can be more freely deformed and adjusted according to the shape and purpose of the individual face.
