<P>PROBLEM TO BE SOLVED: To provide a mask which has simple structure and is manufactured at low costs and where fogging of glasses is suppressed when the mask is worn. <P>SOLUTION: In the mask 1A, a mask main body 2 having a wrap size for both nostrils and a mouth is provided with a sticky layer 4 at a part above the nostrils when the mask is worn. Since the mask 1A is provided with the sticky layer 4 at the part above the nostrils of a user, rising of exhaled breath is prevented by sticking the sticky layer 4 to the face surface of the user. As the result, fogging of the glasses positioned above the mask is suppressed. It is possible either to put codes for hanging the mask to the ears separately to the mask main body 2 or to provide a part for hanging the mask to the ears integrally to the mask main body. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a mask used for cold prevention and the like. More specifically, the present invention relates to a mask having a configuration in which the mask body covering both nostrils and the mouth is configured to suppress fogging of spectacles (glasses) users.

  Conventionally, a mask has been widely used for catching a cold, preventing it, or preventing dust from being sucked. Furthermore, the mask is used to relieve hay fever in the early spring when pollen comes in. A general mask has a structure including a mask main body that covers a nostril and a mouth of a face, and an ear hook rubber for holding the mask main body. However, since the mask body covers the user's nostril and mouth, the breath (sigh) discharged by the user himself rises along the inner surface of the mask. Therefore, when the user wears glasses, the glasses lens may be fogged by his / her breath. In particular, this is likely to occur in winter when colds are prevalent.

  As mentioned above, when the glasses are clouded, the front cannot be seen, which is very inconvenient. In this regard, Patent Document 1 proposes a sanitary mask to which a structure for suppressing fogging of glasses is added. This mask is formed of a mask main body with an ear hook and a thin-film band. A thin film strip is integrally attached to the upper edge of the mask body and protrudes upward.

  The thin film strip is made of an elastic material. As such a thin film-like strip, a thin film of a material such as silicon resin, polyethylene resin, vinyl chloride resin, elastomer resin, rubber or the like is used. In addition, it is desirable that this thin film-like strip is transparent or translucent so that it is as inconspicuous as possible when worn. The thin-film band is integrated by sewing or bonding the lower end edge side over the entire width of the upper end edge of the mask body.

  The mask of patent document 1 which has said structure is used, setting it as the state which presses down the upper surface of a thin film-like strip at the lower edge of a spectacles frame. When used in this manner, the face and the thin film band are in close contact with each other, so that exhalation does not leak upward and fogging of the glasses can be prevented.

JP 2001-565 A

  However, the mask disclosed in Patent Document 1 is one in which a thin-film band formed of a material having completely different properties is integrated with an upper end of a mask body formed of gauze or the like by stitching or the like. For this purpose, it is necessary to prepare a thin film strip separately from the mask body and sew it. For this reason, the number of parts increases, and the number of manufacturing steps increases, resulting in a significant increase in cost. In addition, this mask is very troublesome because it is necessary to perform an operation of pressing the thin film strip on the lower edge of the frame of the glasses every time it is worn.

  Furthermore, the shape of a person's face varies. For example, the relative position of the lower edge of the glasses and the upper edge of the mask differs between a person with a long face and a high nose and a person with a round face and a low nose. As a result, it is preferable for a person with a long face and a high nose to have a long thin film band in the direction of the nasal muscles, but this same thin film band is too long for a round face with a low nose. Will get in the way. As described above, since it is difficult to commonly use a mask of Patent Document 1 that has a pre-made size like a conventional mask, a mask suitable for the user's face is manufactured, or a considerably large number of ready-made products are available. It is necessary to prepare a type of mask. This also increases the cost.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a mask that can be manufactured at a low cost with a simple structure and can suppress fogging of glasses when worn. Is.

  The above object can be achieved by a mask characterized in that a mask main body having a size covering both the nostrils and the mouth is provided with an adhesive layer in a portion above the nostrils when worn.

  According to the present invention, since the mask main body is provided with the adhesive layer in a portion above the user's nostril, the increase in the breathing is prevented by the adhesive layer sticking to the user's face. As a result, fogging of the glasses positioned above the mask can be suppressed. In addition, a string for ear hooks or rubber may be added separately to the mask main body, or an ear hook portion formed integrally with the mask main body may be provided.

  Moreover, you may employ | adopt the structure where the said adhesion layer is extended to the both sides part of the said mask main body. In this case, since exhalation that leaks from the side is suppressed, fogging of the glasses can be prevented more reliably and the mask position can be prevented from shifting.

  Further, a structure in which the adhesive layer is formed in an annular shape on the peripheral edge of the mask main body may be adopted. In this case, since exhalation leaking from the peripheral portion is suppressed, fogging of the glasses can be prevented more reliably and the mask position can be prevented from shifting. In addition, when an adhesive layer is provided in an annular shape in this way, dust and pollen entering from the outside can be cut, so that a mask with an improved original function is obtained. Further, when the mask body can be held on the face only by the adhesive layer, the ear hooking portion may be omitted.

  Further, a structure may be employed in which a collar portion folded inward is added to the peripheral edge portion of the mask main body, and the adhesive layer is provided on the collar portion. Providing the buttock in this way can provide a margin between the inner surface of the mask body and the user's face. And what is necessary is just to form the said adhesion layer continuously or discontinuously as needed.

  According to the present invention, it is possible to provide a mask that can be manufactured at a low cost with a simple structure and that can suppress fogging of glasses when worn.

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

  FIG. 1 shows the mask 1A of the first embodiment. The mask 1A shown in FIG. 1 is sized to cover both nostrils and mouth, and has a substantially rectangular mask body 2 and ear-hook rubbers 3, 3 provided on both sides of the mask body 2. And. The mask body 2 is formed of a material having air permeability like a conventional mask and having a filter function for capturing dust and pollen. As such a material, for example, artificial fibers such as gauze, bleached cotton, hemp, polyamide synthetic fiber, non-woven fabric, paper, synthetic paper, sponge and the like can be adopted. These materials may be formed in multiple layers as necessary. The same material may be laminated to form a laminated structure, or a laminated structure in which different materials are combined.

  Similar to a conventional general mask, both sides of the mask body 2 are sewn together at predetermined widths from both ends, and passage portions 2a and 2a penetrating vertically are formed. Ring-shaped earring rubbers 3 and 3 are passed through the left and right passage portions 2a and 2a. When gauze, bleached cotton or the like is used as the material of the mask body 2, the structure as described here is obtained. However, when a nonwoven fabric, sponge or the like is used as a material, the degree of freedom in shape processing is high. Moreover, the material may be rich in elasticity. In such a case, the mask main body 2 and the ear hook portion may not be formed separately, and an integrated mask may be used. Furthermore, the shape of the mask main body 2 is not limited to the rectangle illustrated in FIG. 1, and may be a curved shape according to an uneven face shape. In short, in the present invention, the shape and material of the mask body 2 are not particularly limited.

  An adhesive layer 4 is provided above the inner surface (the surface on the side in contact with the face) of the mask body 2. The adhesive layer 4 is formed at least in a portion above the nostril when the user wears the mask 1A on the face. The adhesive layer 4 is a portion formed so as to stick to a part of the face when the user wears the mask body 2. The adhesive layer 4 is formed, for example, by applying an adhesive on the mask body 2. What is necessary is just to select suitably the adhesive used here while being stably hold | maintained on the raw material of the mask main body 2, and being detachable with respect to a human skin, and obtaining desired adhesive force. . In addition, it is preferable to select a pressure-sensitive adhesive that does not cause irritation to the user even when used for a long time and whose adhesive strength does not easily decrease even when used repeatedly. As such an adhesive, for example, an acrylic adhesive can be used. Among acrylic pressure-sensitive adhesives, it is particularly preferable to employ a solvent-type pressure-sensitive adhesive made of an acrylic copolymer with a small amount of residual monomer. This type of pressure-sensitive adhesive is less irritating to stuck skin and can be suitably used because it has a function of retaining appropriate moisture.

  In addition, when the mask body 2 is formed of gauze, bleached cotton or the like, it is assumed that the mask body 2 is repeatedly used after being washed. Therefore, when a mask material that can be washed with water is used, an adhesive that can maintain the adhesive strength without detaching from the mask body 2 even if washed with water, or that restores the adhesive strength by washing with water, is appropriately selected. It is desirable to adopt. Also in this respect, the above solvent-type pressure-sensitive adhesive can be employed.

  FIG. 2 is a diagram showing an example of wearing the mask 1A. The mask 1A shown in FIG. 1 is used as shown in FIG. As shown in this figure, since the adhesive layer 4 provided on the upper part of the mask body 2 sticks to a part of the user's face (above the nostril), there is a gap between the upper part of the mask body 2 and the face. Disappears. As a result, since it is possible to prevent the mask user's own breath from rising, it is possible to suppress the lens 11 of the glasses 10 positioned above the mask 1A from being clouded.

  As described above, the mask 1 </ b> A of the first embodiment can suppress the lens fogging of the glasses due to the mask user's own breath with a simple device that the adhesive layer 4 is provided on the inner surface on the upper side of the mask body 2. In particular, a process of simply applying an adhesive to a part of the mask body 2 does not include a cumbersome process such as stitching a thin film-like band formed of an elastic material on the upper edge of the mask body as in the prior art. Can be manufactured at low cost. Moreover, the mask 1A of the present embodiment is simply mounted in the same manner as the conventional mask, and the adhesive layer 4 sticks to the face above the user's nostril to prevent an increase in sigh. Therefore, since it is not necessary to perform troublesome operations such as pressing the upper surface of the thin film strip with the lower edge of the spectacle frame, it may be used in the same manner as a conventional general mask.

  Further, since the adhesive layer 4 acts to stop the mask body 2 on the user's face, the ear hooking rubbers 3 and 3 can be weakened. Even when a conventional mask is worn, even if the user feels uncomfortable due to the tightness of the rubber for the ear, it is possible to obtain a secondary effect that the mask is easy to use.

  Hereinafter, another embodiment according to the present invention will be described. However, the same parts as those of the mask 1A shown in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 3 is a view showing the mask 1B of the second embodiment. In the mask 1 </ b> B shown in FIG. 3, the adhesive layer 4 extends on both side portions of the mask body 2. When the adhesive layer 4 is provided also on the side portion of the mask body in this way, a structure that can suppress the exhalation that leaks from both sides of the mask and rises is obtained. Therefore, the lens fogging of the glasses can be suppressed more reliably than the mask 1A of the first embodiment. Further, since the portion of the adhesive layer 4 is increased, the mask body 2 can be stably held on the face, so that the mask can be prevented from being displaced. Further, the ear hook rubber 3 can be further weakened.

  The adhesive layers 4 provided on both side portions may be arranged so as to be continuous with the adhesive layer 4 (adhesive layer 4 shown in FIG. 1) present in the upper portion from the viewpoint of reliably preventing an increase in exhalation. preferable. However, it is not essential to always provide the adhesive layer 4 continuously. Therefore, you may arrange | position the adhesion layer 4 provided in a side part discontinuously as shown in FIG. Of course, you may form continuously also about the adhesion layer 4 provided in both sides.

  The pressure-sensitive adhesive layer 4 (the pressure-sensitive adhesive layer 4 shown in FIG. 1) disposed above the nostril is preferably formed continuously long in order to prevent the increase in exhalation with certainty. However, in the central portion, the root of the nose (nasal root portion) rises, so even if the adhesive layer 4 is cut slightly (that is, even if the central portion 4CE shown in FIG. Can be suppressed.

  FIG. 4 is a view showing the mask 1C of the third embodiment. In the mask 1 </ b> C shown in FIG. 4, the adhesive layer 4 is continuously formed on the entire periphery of the mask body 2. Thus, if the adhesion layer 4 is formed in a perfect ring shape, the gap between the face and the mask body 2 can be eliminated. Therefore, since the sigh leaking out between the face and the mask main body 2 can be almost eliminated, the fogging of the glasses can be more reliably suppressed. And since the mask 1C of this Example 3 implement | achieves the structure which prevented air from entering from a clearance gap, it can shutter out dust and pollen reliably. Therefore, the mask 1C according to the third embodiment can not only suppress the lens fogging of the glasses, but also enhances the original function of reliably protecting the user from dust and pollen. In addition, when the adhesive force of the adhesive layer 4 is increased and the adhesive force capable of holding the mask body 2 on the face is applied, a mask (stringless mask) in which the rubber 3 for the ear hook is eliminated can be obtained.

  FIG. 5 is a view showing the mask 1D of the fourth embodiment. The mask 1D shown in FIG. 5 is the same as 1C of Example 3 in that the adhesive layer 4 is provided on the entire periphery of the mask body 2, but the adhesive layer 4 other than the upper part is formed discontinuously. Is different. This mask 1D has a structure in which air permeability is considered more than the mask 1C of the third embodiment. This mask 1D has a function of preventing eyeglass lens fogging and a function of shuttering out dust and pollen in accordance with the mask 1C of the third embodiment. Moreover, this mask 1D can suppress the adhesive to be used and can reduce cost rather than the mask 1C of Example 3. FIG. This mask 1D can also be used as a stringless mask when the adhesive strength of the adhesive layer 4 is increased and an adhesive force capable of holding the mask body 2 on the face is applied.

  FIG. 6 is a view showing the mask 1E of the fifth embodiment. 6A is a perspective view of the mask 1E, and FIG. 6B is a side view thereof. The mask 1E shown in FIG. 6 is provided with a gusset (gusset) portion 5 that is turned inwardly on the upper portion of the mask body 2, and the adhesive layer 4 described above is provided on the heel portion 5. The collar portion 5 is provided, for example, by forming the same material as that of the mask body 2 in a band shape and sewing or adhering. Providing the collar portion 5 in this way can provide a space between the inner surface of the mask body 2 and the user's face. Therefore, it becomes easy to stick the adhesive layer 4 to the face while corresponding to the face having the uneven portion. As a result, the mask body 2 can also be prevented from shifting. Although FIG. 6 shows an example in the case where the adhesive layer 4 of Example 1 is formed on the flange portion 5, it is not limited thereto. The structure of this embodiment may be applied to the mask 1C of the third embodiment shown in FIG. Although not shown as an example, the structure of this example may be applied to a mask in which the adhesive layer 4 continuous on the upper part and both side parts is formed.

  As described above, the masks 1A to 1E according to the embodiments have the adhesive layer on the portion where the mask body is above the nostril of the user, so that the fogging of the glasses positioned above the mask with a simple structure is provided. Can be suppressed.

  The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims.・ Change is possible.
