Description

[Technical field]

[0001] The present invention relates to a mask shape retainer for retaining the shape of a mask. [Background technology]

[0002] Conventionally, in masks used for dust protection or pollen protection, a configuration is known in which a mask body is made of cloth or nonwoven fabric and a shape-retaining member is arranged inside the mask body (see, for example, Patent Document 1). Patent Document 1 describes a technique in which the mask body is made of a flexible sheet-like member on the outer surface side and a shape-retaining member made of an elastic material on the inner surface side. According to the mask described in Patent Document 1, the shape-retaining member formed into a three-dimensional shape that does not follow the contours of the face prevents the inside of the sheet-like member from contacting the surface of the face, such as the mouth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] A first embodiment of the present invention will be described below with reference to the drawings. A mask shape retainer (hereinafter simply referred to as "retainer") 1 according to this embodiment can be used in masks used for dust protection, pollen protection, splash prevention, etc. As shown in Figures 1 and 2, the retainer 1 is used by being placed inside the mask body M in a state where it is hung on the upper end edge MU of the mask body M, which is a sheet-like member made of cloth or nonwoven fabric.

[0015] In this way, the holder 1 according to this embodiment is configured separately from the mask body M and is detachable. That is, the holder 1 can be used repeatedly with disposable and other commercially available masks, making it possible to reduce maintenance costs.

[0016] In this specification, the direction of the holder 1 is defined from the viewpoint of a user wearing a mask. That is, as shown in Figures 1 and 2, the front in the field of vision of a user wearing a mask is the front of the holder 1, and similarly, the left side in the field of vision of the user (the right side as viewed from the user) is the left side of the holder 1.

[0017] The holder 1 according to this embodiment is made of soft resin and is formed in a bilaterally symmetrical shape. As shown in Figures 3 to 5, the holder 1 includes a main body 2 having a curved shape that protrudes forward, and locking portions 3, 3 extending from the left and right sides of upper sides 21t, 21t of the main body 2. The main body 2 according to this embodiment is configured in a mesh-like shape including an outer portion 21 that forms the outer shape of the main body 2 and is formed in a hollow ring shape on the inside, and connecting portions 22 that connect multiple points of the outer portion 21 to each other.

[0018] It is also possible to form the main body 2 in a continuous (closed) curved shape, rather than in a mesh shape as in this embodiment. However, from the viewpoint of breathability and weight reduction of the holder 1, it is preferable to form the main body 2 in a mesh shape as in this embodiment. In addition, the arrangement of the connecting parts 22 when forming the mesh shape is not limited to this embodiment, and other shapes are possible.

[0019] In addition, since the appropriate size of the main body 2 varies depending on the size of the user's face, it is preferable to select the most appropriate one for each user from among multiple types of retainers 1 with different sizes of main body 2. In this case, in order to increase the effect of the retainer 1, it is more preferable to adopt one in which the lower end of the main body 2 abuts against the front of the user's chin (see Figs. 2 and 6).

[0020] 3 to 5, the upper central portion of the main body 2 is formed to be inclined downward toward the front side. The upper central portion of the main body 2 is formed with an upper arch portion 21a that is curved into a substantially U-shape in a front view and a plan view.

[0021] As shown in Figures 1, 2, and 6, when the holder 1 is attached to the mask body M and used, the user's nose (bridge and tip of the nose) is inserted inside the upper arch portion 21a. In other words, the upper arch portion 21a is positioned so as to straddle the user's nose. This prevents the holder 1 from interfering with the user's nose. Even if the holder 1 is displaced up and down when the user talks while using the holder 1, the upper arch portion 21a displaces the outside of the nose, preventing interference between the holder 1 and the nose.

[0022] 3 to 6, a lower arch portion 21b curved to bulge forward is formed in the lower center of the main body 2. As a result, even if the retainer 1 is displaced up and down when the user talks while using the retainer 1, the lower arch portion 21b allows the jaw to displace, so the user can talk without hindrance.

[0023] In the retainer 1 according to this embodiment, as described above, the upper central portion of the main body 2 is formed as a curved upper arch portion 21a, and therefore the upper side 21t of the main body 2 is formed on both the left and right sides. The locking portions 3-3 extend from the inside to the outside at each of the upper sides 21t-21t. As shown in Figs. 4 and 5, the tip portions 3a-3a of the respective locking portions 3-3 are disposed forward of the upper sides 21t-21t. Also, as shown in Fig. 3, the tip portions 3a-3a are disposed at the same position as or below the upper sides 21t-21t in the up-down direction.

[0024] When using the holder 1, as shown in Figs. 1 and 2, the holder 1 is placed inside the mask body M, and the locking parts 3-3 are hooked onto the upper end edge MU. In this case, the tip 3a of the locking part 3 is located forward of the upper end edge 21t of the main body 2, and the tip 3a is located at the same position as or lower than the upper end edge 21t in the vertical direction. Therefore, when the holder 1 is locked to the mask body M, the upper end edge MU is sandwiched between the upper end edge 21t and the tip 3a, so that the holder 1 can be stably locked to the mask body M. In other words, the holder 1 can stabilize the position inside the mask body M, and can be made less likely to come off the mask body M.

[0025] 3 to 5, in the holder 1 according to this embodiment, the locking portions 3-3 extend from the upper edges 21t-21t in a back-to-back manner from the inside to the outside. This allows the holder 1 to be naturally locked to the upper end edges MU that extend backwards as they widen to both the left and right sides when the mask body M is worn along the user's face, as shown in Fig. 2. This allows the holder 1 to be easily attached to and detached from the mask body M.

[0026] In the holder 1 according to this embodiment, a projection 3b projecting rearward is formed on the tip 3a of each locking portion 3. This allows the projection 3b to be engaged with the upper end edge MU when the upper edge 21t and the tip 3a pinch the upper end edge MU, making it possible to more stably lock the holder 1 to the mask body M.

[0027] 5, the rear tip of the projection 3b in the holder 1 is disposed rearward of the front surface of the portion of the main body 2 that is closest to the projection 3b. This allows the projection 3b to be inserted deeper into the upper end edge MU when the upper end edge MU is sandwiched between the upper edge 21t and the tip 3a. This further stabilizes the position of the holder 1 inside the mask body M, making it even more difficult for the holder 1 to come off from the mask body M.

[0028] Next, a second embodiment of the present invention will be described with reference to the drawings. Like the holder 1 according to the above embodiment, the holder 101 according to this embodiment can be used for masks used for dust protection, pollen protection, splash prevention, etc. As shown in Figures 7 and 8, the holder 101 is used by being placed inside the mask body M in a state where it is hung on the upper end edge MU of the mask body M, which is a sheet-like member made of cloth or nonwoven fabric.

[0029] In this way, the holder 101 according to this embodiment is also configured separately from the mask body M and is detachable. That is, the holder 101 can be used repeatedly with disposable and other commercially available masks, making it possible to reduce maintenance costs.

[0030] Holder 101 according to this embodiment is made of soft resin and is formed in a bilaterally symmetrical shape. As shown in Figures 9 to 11, holder 101 includes main body 102 having a curved surface shape protruding forward, and locking portions 103 extending from the left and right sides of upper sides 121t of main body 102.

[0031] The main body 102 according to this embodiment includes an upper body part 121 that constitutes the upper part of the main body part 102 and is formed in a hollow ring shape on the inside, and a lower body part 122 that is formed below the upper body part 121 and constitutes the lower part of the main body part 102. A connecting part 123 that connects the upper side and the lower side of the upper body part 121 is provided in the center part in the left-right direction of the upper body part 121.

[0032] Since the appropriate size of the main body 102 varies depending on the size of the user's face, it is preferable to select the most appropriate one for each user from among multiple types of holders 101 with different sizes of main body 102. In this case, in order to maximize the effect of holder 101, it is more preferable to adopt one in which the lower end of main body 102 abuts against the front of the user's chin (see Figs. 8 and 12).

[0033] 9 to 11, the upper central portion of the main body portion 102 is formed to be inclined downward toward the front side. The upper central portion of the main body portion 102 is formed with an upper arch portion 121a that is curved into a substantially U-shape in a front view and a plan view.

[0034] As shown in Figures 7, 8, and 12, when the holder 1 is attached to the mask body M and used, the user's nose (bridge and tip of the nose) is inserted inside the upper arch portion 121a. In other words, the upper arch portion 121a is disposed so as to straddle the user's nose. This prevents the holder 101 from interfering with the user's nose. In addition, even if the holder 101 is displaced up and down when the user talks while using the holder 101, the upper arch portion 121a displaces the outside of the nose, so that interference between the holder 101 and the nose can be prevented.

[0035] 9 to 11, deformable portions 121b-121b that allow elastic deformation of the upper outer portion of main body portion 102 are formed on each of the left and right sides of upper main body portion 121. Specifically, deformable portions 121b in upper main body portion 121 are formed to be thinner than other portions, and bending deformation is allowed at deformable portions 121b. These deformable portions 121b-121b allow the upper outer portion of main body portion 102 to elastically deform in the front-rear direction.

[0036] As a result, when a user puts mask M with holder 101 attached on their face, holder 101 can be deformed to fit the contours of the user's face. In detail, deformation-allowing portions 121b-121b can elastically deform the upper outer side of main body portion 102 backward (toward the user). In this way, holder 101 according to this embodiment makes it possible to improve the fit when holder 101 is used.

[0037] 9 to 12, a lower arch portion 122a curved to bulge forward is formed in the lower center of the lower main body portion 122. As a result, even if the retainer 101 is displaced up and down when the user talks while using the retainer 101, the lower arch portion 122a allows the jaw to displace, so the user can talk without hindrance.

[0038] In the holder 101 according to this embodiment, as described above, the upper central portion of the main body 102 is formed as a curved upper arch portion 121a, and therefore the upper sides 121t of the main body 102 are formed on both the left and right sides. The locking portions 103 extend back-to-back from the inside to the outside on each of the upper sides 121t. When using the holder 101, as shown in Figures 7 and 8, the holder 101 is placed inside the mask body M, and the locking portions 103 are hooked onto the upper end side MU.

[0039] In the holder 101 according to this embodiment, as shown in Figures 9 to 11, the locking portions 103 extend from the upper edges 121t to the outside in a back-to-back manner. As a result, when the mask body M is worn along the face of a user, as shown in Figure 8, the holder 101 can be naturally locked to the upper end edge MU that extends backward as it widens on both the left and right sides. This makes it possible to easily attach and detach the holder 101 to and from the mask body M.

[0040] In the holder 101 according to this embodiment, a projection 103b projecting rearward is formed on the tip 103a of each locking portion 103. This allows the projection 103b to be engaged with the upper end edge MU when the upper end edge MU is sandwiched between the upper edge 121t and the tip 103a, making it possible to more stably lock the holder 101 to the mask body M.

[0041] 11, the rear tip of protrusion 103b in holder 101 is disposed rearward of the front surface of the portion of main body 102 closest to protrusion 103b. This allows protrusion 103b to be inserted deeper into upper end edge MU when upper edge 121t and tip 103a pinch upper end edge MU. This further stabilizes the position of holder 101 inside mask body M, making it even more difficult for holder 101 to come off mask body M.

[0042] Furthermore, when the user puts the mask M with the holder 101 attached on the face, if the deformation-allowing portions 121b-121b elastically deform the upper outer side of the main body 102 backward (toward the user), the protrusions 103b can be further inserted into the upper end side MU. This allows the holder 101 to be more stably engaged with the mask main body M. [Explanation of symbols]
