Description

  The present invention relates to a three-dimensional variable sanitary mask that can deform a flat mask into a three-dimensional shape.

In such a three-dimensional variable sanitary mask, the three-dimensional shape of the mouthpiece part deformed into a three-dimensional shape is maintained by giving tension to the mouthpiece part.

  Patent Document 1 discloses that a folded portion (folded portion) is formed in a mouthpiece portion of a mask. When this folding part is pulled up and down, the folding line of the folding part spreads in a V-shaped cross section and extends to the left and right (see FIGS. 3 and 4 of Patent Document 1), and a tensioning action is obtained at the mouthpiece. Therefore, the shape of the three-dimensionally formed mouthpiece is maintained.

  Patent Document 2 discloses that a mouthpiece portion is formed by superimposing left and right flat sheet members in a palm form and joining one side extending vertically. This joint portion is positioned in the longitudinal direction at the center of the mouthpiece when the sheet is opened to the left and right. Moreover, this junction part is hard. Therefore, a tensioning action is obtained in the longitudinal direction at the center of the mouthpiece. Therefore, the shape of the mouthpiece portion of the mask formed in three dimensions is maintained.

  The three-dimensional mask of Patent Document 1 can adjust the vertical dimension by adjusting the degree of opening of the folded portion (folded portion). However, when the mouthpiece becomes wet, the tensioning action of the folding line is weakened. Therefore, when the mouthpiece is damp due to breathing or the like, the three-dimensional shape of the mouthpiece is likely to collapse.

  The three-dimensional mask of Patent Document 2 is hard to be affected by moisture because the vertical direction at the center of the mask is bonded and hardened. Therefore, even if the three-dimensionally formed mouthpiece is damp, its shape is difficult to collapse. However, this mask cannot freely adjust the three-dimensional shape or size of the mouthpiece.

  The present invention can maintain the three-dimensional shape of the mouthpiece even when used for a long time, and can adjust the three-dimensional shape to match the size of the user's face. The problem is to provide a mask.

  The three-dimensionally variable sanitary mask of the present invention (Claim 1) includes a flat mouthpiece having a folded portion extending in the left-right direction in a state where a plurality of nonwoven fabrics are overlapped, and both sides of the mouthpiece. In the three-dimensionally variable sanitary mask comprising a hook for wearing on the ear, the shape holding member having flexibility is accommodated in the folded portion.

  It is preferable that a slit-shaped bag extending in the left-right direction is formed between the folded portions, and the shape holding member is accommodated in the slit-shaped bag.

  In such a mask, it is preferable that the folding part for accommodating the shape holding member is provided at the center part in the vertical direction of the mouthpiece part (Claim 3).

  In addition, it is preferable that a plurality of the folding parts are arranged in the vertical direction, and the shape maintaining members are respectively accommodated in the adjacent folding parts.

  Furthermore, it is preferable that both ends of the shape holding member are fixed to both ends of the folded portion.

  In addition, it is preferable that a flexible support member is provided at the upper end of the mouthpiece so as to allow the upper end to follow the nose.

  Moreover, it is preferable that a slit-shaped bag is formed in the folding portion, and the shape holding member is accommodated in the slit-shaped bag.

  The three-dimensionally variable sanitary mask of the present invention (Claim 1) includes a flat mouthpiece having a folded portion that is elongated in the left-right direction in a state where a plurality of nonwoven fabrics are overlapped, and the mouthpiece Since the hook part is attached to the ears on both sides of the part, the mouthpiece part can be formed three-dimensionally by pulling the folding part up and down and expanding. In addition, the size of the three-dimensional shape of the mouthpiece can be adjusted by adjusting the tension of the folding portion. In this invention, since the flexible shape holding member is accommodated in the folding part, the mouthpiece has a tensioning action. Therefore, the three-dimensionally formed mouthpiece can hold the three-dimensional shape more reliably. Therefore, the mouthpiece portion of the sanitary mask of the present invention can be formed and adjusted to a three-dimensional shape having a size corresponding to the user's face by combining the actions of the folding portion and the shape holding member. In addition, the three-dimensional shape can be more reliably maintained.

When a slit-like bag extending in the left-right direction is formed between the folding parts, and the shape holding member is accommodated in the slit-like bag (Claim 2), the shape holding member is an inner surface of the bag. It is accommodated in a state of being in close contact with. Therefore, when the mouthpiece portion is three-dimensionally formed, the folding portion and the shape holding member are in close contact with each other, so that the three-dimensional shape of the mouthpiece portion is more reliably held.

  When the folding part that accommodates the shape holding member is provided at the center part in the vertical direction of the mouth pad part (Claim 3), the three-dimensional mouth pad part has a tensile force at its center, Its shape is more difficult to collapse. Moreover, the shape is stable. Therefore, when the mask is used, the space formed between the mouthpiece and the mouth facing the center of the mouthpiece is maintained even during long-time use.

  Further, when a plurality of the folding parts are arranged in the vertical direction, and the shape holding member is accommodated in each of the adjacent folding parts (Claim 4), the tension of the mouthpiece part increases the strength. . Moreover, the three-dimensional shape of the mouthpiece is further stabilized. Therefore, the space formed between the mouthpiece and the mouth is more reliably maintained.

  Furthermore, when both ends of the shape holding member are fixed to both ends of the folded portion (Claim 5), the shape holding member and the mouthpiece portion are integrated. Therefore, both ends of the curved shape-holding member are supported by both ends of the mouthpiece. Therefore, since the shape of the three-dimensionally formed mouthpiece is prevented, its shape is maintained for a long time.

  Moreover, when the flexible support member for making the said upper end along a nose is provided in the upper end of the said mouth rest part (Claim 6), it becomes possible for the mouth rest part to latch an upper end to a nose. ing. Therefore, the mouthpiece is easily stabilized on the face and the mouth. Therefore, the space formed between the mouthpiece portion and the mouth that are three-dimensionally formed is more reliably maintained.

Further, when a flexible support member is provided at the lower end of the mouthpiece portion so as to follow the lower end to the chin (Claim 7), the mouthpiece portion is more stable on the face and mouth. Become. Therefore, the space formed between the mouthpiece portion and the mouth that are three-dimensionally formed is more reliably maintained. Further, the shape of the three-dimensional mouthpiece is further maintained even when used for a long time.

It is the front view which notched some masks of this invention. 2 is a schematic view of a central longitudinal section of the mask of FIG. 1. It is an expanded sectional view of the AA line of FIG. It is an expanded sectional schematic of the BB line of FIG. It is a front view of the shape holding member of FIG. It is a side view of the use condition which formed three-dimensionally the mask of FIG.

  FIG. 1 shows a mask A of the present invention. The mask A includes a mouthpiece 1 and ear hooks 2 provided on both sides of the mouthpiece 1.

As shown in FIGS. 2 and 3, the mouthpiece 1 includes a nonwoven fabric body 3 formed by superposing three layers of a nonwoven fabric 3 a on the front side, an intermediate nonwoven fabric 3 b, and a nonwoven fabric 3 c on the backside, and the mouthpiece 1 It consists of the shape holding member 4 accommodated in the inside. The intermediate layer nonwoven fabric 3b has antibacterial properties.
In addition, the total number of the said nonwoven fabric body is not restricted to this embodiment. Further, the number of antibacterial nonwoven fabrics is not limited to the above. The antibacterial nonwoven fabric is preferably provided, but may not be provided.

  As shown in FIG. 1, the mouthpiece 1 forms a folded portion 6 by horizontally folding the center of the nonwoven fabric body 3 in the vertical direction and heat-sealing the periphery. Although a plurality of the folding parts 6 are provided, it is preferable to provide them symmetrically as shown in FIG. Therefore, since the folding part 6 is heat-sealed at both ends and the center is not welded, it can be expanded in the vertical direction.

Since the folding part 6 opens equally by pulling the upper side and the lower side of the mouthpiece part 1 outwardly, a vertically symmetrical three-dimensional shape can be obtained easily and reliably (see FIG. 6). Moreover, it can also return to an original flat state from this shape.
Thus, since the folding part 6 opens symmetrically and expand | deploys, the mouthpiece part 1 exhibits a favorable appearance. However, it may be formed with the folding direction aligned in one direction.

  The shape holding member 4 is made of synthetic resin and has flexibility. As shown in FIG. 5, the width is as narrow as about 3 mm and the thickness is as thin as about 1 mm, and the length is the same as the lateral width of the mouthpiece 1 as shown in FIG. 1. The shape holding member 4 can be formed into a three-dimensional shape by bending it into a mountain shape or bending it into a convex shape. It is also possible to hold a three-dimensionally formed shape. And it is also possible to return to the original flat state.

  As shown in FIGS. 1 to 3, the shape holding member 4 is accommodated in the folding portion 6. In detail, it arrange | positions in parallel with the folding line of the folding part 6a in the center of the folding part 6a located in the center of the mouthpiece part 1 (refer FIG. 1), and between the nonwoven fabric 3b of an intermediate | middle layer, and the nonwoven fabric 3c of the back side (See FIG. 2), both ends thereof are overlapped with both side ends of the mouthpiece 1. Both ends of the shape holding member 4 are welded to both ends of the mouthpiece 1 when the periphery of the mouthpiece 1 is heat-sealed 5 as described above (see FIG. 3).

  Furthermore, since the three-layered nonwoven fabric 3a, 3b, 3c is heat-sealed 5a immediately above the upper side and immediately below the lower side, the shape holding member 4 has a form accommodated in the slit-like bag 7. It has become. Thus, since the shape holding member 4 is integrated with the folding portion 6a and the bag 7, it is prevented from moving in the vertical direction of the mouthpiece portion 1, and since it is permanently installed at a fixed position, Can be bent easily and reliably. Therefore, the mouthpiece 1 can be three-dimensionally formed reliably and rapidly, and the tensioning action at the center is reliable and stable, so that it is prevented from being easily deformed. For example, even if the center of the surface of the mouthpiece 1 is pressed, or even if the mouthpiece is damp due to breathing or the like, the overall deformation of the mouthpiece is prevented by the tensioning action at the center of the mouthpiece.

  Therefore, as shown in FIG. 5, the mouthpiece portion 1 formed in a three-dimensional manner is integrated with the center portion in the vertical direction and the shape holding member 4 in a very stable state, and thus the center obtains a certain tension. ing. Therefore, the three-dimensionally formed mouthpiece 1 can maintain its appearance beautifully by its tension.

  Further, as shown in FIG. 1, the three layers of the nonwoven fabrics 3a, 3b, and 3c are heat-sealed 5a at the center in the vertical direction of the mouthpiece, so that the nonwoven fabric 3c on the back side has the folded portion 6 Even in the expanded state, it can be integrated with the other two layers of nonwoven fabrics 3a and 3b. Therefore, when the mask is worn, the uncomfortable feeling that the nonwoven fabric 3c on the back surface side is sucked into the mouth and comes into contact with the lips is prevented.

  Further, as shown in FIG. 6, a space S is formed between the mouthpiece 1 and the mouth M facing the center in the vertical direction. Further, the space S is securely held by the tensioning action by the shape holding member 4. Further, the mouthpiece 1 is prevented from coming into contact with the mouth M, but especially in the case of women, the lipstick is prevented from adhering. Therefore, this sanitary mask is very hygienic.

  Since the space S is held in a very stable state, the mouth M is always easy to move. Therefore, since it is possible to speak with a clear pronunciation even when the mask is worn, there is no complication such as dare to wear the mask.

  Further, as shown by a two-dot chain line in FIG. 6, it is preferable that the same folding member 6 accommodates the same one as the shape holding member 4 in the same manner. In this case, the space formed between the mouthpiece and the mouth can be further reliably held.

  The ear hook 2 is a thin string having elasticity. The thin string is preferably a rubber string. The elastic cord gently touches the cheek at the end of the mouthpiece and expands and contracts in response to the movement of the cheek. Therefore, the three-dimensional shape can be reliably retained. However, even if it is a thin string with no elasticity, it may not be a rubber string as long as the mouthpiece is easily adhered to the cheek.

  In addition to the above-described embodiment, as shown by the two-dot chain line in FIG. 6, the shape holding member 4 may be provided in the same folding section 6b as described above. In this case, the three-dimensional shape of the mouthpiece 1 is further maintained in a certain state.

  In addition, as shown by a two-dot chain line in FIG. 6, a flexible support member 10 may be provided at the upper end of the mouthpiece portion 2 of the above-described embodiment so that the upper end is aligned with the nose. Moreover, you may provide the support member 11 which has the flexibility for making a lower end follow a jaw. These supporting members are preferably made of the same material as the shape maintaining member. Moreover, it is preferable that the both ends are welded to the both ends of a mouthpiece part similarly to the said shape holding member.
