Description

The present invention relates to a face guard used in combination with a mask and which can be used to prevent droplet infection.

Conventionally, an eye protection shield used in combination with a mask to protect the user's eyes has been known. For example, Patent Document 1 discloses a shield composed of an attachment portion E1 attached to a non-woven fabric mask and an eye protection portion E2 capable of protecting the user's eyes. In this shield, the attachment portion E1 can be connected to the non-woven fabric mask by using a hook-and-loop fastener (mechanical fastener) or an adhesive that can be connected to the non-woven fabric.

Japanese Unexamined Patent Publication No. 2018-115418

However, when manufacturing the eye protection shield according to Patent Document 1, in addition to the eye protection portion E2 made of a relatively inexpensive resin, the mounting portion E1 is manufactured, and the manufactured mounting portion E1 is attached to the eye protection portion E2. A process is required, and there has been a demand for a face guard that can be manufactured by a simpler manufacturing process and can reduce the manufacturing cost. Further, the eye protection shield according to Patent Document 1 is intended to improve convenience for medical professionals, and a surface fastener is engaged with a non-woven fabric mask used by medical professionals or adhered with an adhesive. Since it is configured to be adhered to a non-woven fabric mask, it may not be usable depending on the type of mask material (for example, a cloth gauze mask that is not used by medical staff). Further, since the mounting portion E1 is composed of a hook-and-loop fastener or an adhesive, once it is removed, the connection strength with the mask is lowered, and it is difficult to use it repeatedly from the viewpoint of infection prevention.

An object of the present invention is to provide a face guard that can be manufactured easily and inexpensively, can be used regardless of the type of mask, and can be used repeatedly.

<< First Embodiment >>
FIG. 1 is a front view showing the face guard 1 according to the first embodiment. Further, FIG. 2 is a diagram showing a state in which the face guard according to the first embodiment is combined with a mask. As shown in FIG. 2, the face guard 1 according to the present embodiment is used in combination with the mask 2, and the mask 2 is passed through the openings 13 and 14 of the face guard 1 through the strings 21 and 22 of the mask 2. By attaching the face guard 1, the face guard 1 is supported by the mask 2, and the face guard 1 can be attached.

Further, as shown in FIG. 1, when not combined with the mask 2, the face guard 1 is flat without being curved. As a result, space can be saved even if a plurality of face guards 1 are laminated, which is also excellent in terms of distribution. Further, the face guard 1 according to the present embodiment can be disposable, but can also be used repeatedly by disinfecting or washing with alcohol or the like.

The configuration of the face guard 1 will be described below. As shown in FIG. 1, the face guard 1 according to the present embodiment is composed of only the eye shield 10 which is a single member. Further, the eye shield 10 is provided on a pair of left and right cheeks 11 and 12 that cover the area around the user's cheeks and temples when the face guard 1 is worn, and a pair of left and right cheeks 11 and 12, respectively. It has openings 13 and 14, a nose pad 15, and a notch 16.

The eye shield 10 is a thin plate-shaped member made of a transparent resin such as polypropylene. As the material of the eye shield 10, transparent resins such as polypropylene, polyethylene, polystyrene, polyvinyl chloride, polyester, polymethyl methacrylate, and polyvinyl acetate can be used, but from the viewpoint of improving visibility, the eye shield 10 is used. It is preferably composed of a highly transparent polypropylene resin.

The eye shield 10 has flexibility and can be curved in the left-right direction. The thickness of the eye shield 10 is preferably 0.5 mm or less, and more preferably 0.3 mm or less. On the other hand, the thickness of the eye shield 10 is preferably thicker than 0.1 mm so that the eye shield 10 does not bend. Further, since the face guard 1 according to the present embodiment is supported at a position close to the face of the user, the eye shield 10 may become cloudy due to the breath of the user or the like, and the visibility may be deteriorated. Therefore, it is preferable that the eye shield 10 is subjected to a boardon (anti-fog) process.

The vertical length L1 of the eye shield 10 is preferably 13 cm or more, more preferably 15 cm or more, and even more preferably 20 cm or more. In this way, by setting the vertical length L1 of the face guard 1 to 13 cm or more, the face guard 1 can be set to a length that protects the user's face from the cheeks to the area around the temples. It is possible to cover not only the area around the eyes or the area around the mouth (around the mask 2) but also the area around both the eyes and the mouth (around the mask 2) of the user.

Further, the eye shield 10 is formed in a tapered shape in which the width W in the left-right direction is long on the upper side and short on the lower side. As a result, as shown in FIGS. 3 and 4, when the user wears the face guard 1, the side edges 11A and 12A of the edge of the eye shield 10 are brought into contact with the edge of the user's face. It is possible to prevent droplet infection from the side of the user's face. 3 is a front view showing a state in which the face guard 1 according to the first embodiment is attached in combination with the mask 2, and FIG. 4 is a front view showing a state in which the face guard 1 according to the first embodiment is attached in combination with the mask 2. It is a side view which shows the state.

Further, the width W1 in the left-right direction at the center position in the vertical direction of the eye shield 10 is preferably 17 cm or more, more preferably 20 cm or more, and further preferably 23 cm or more. Further, in the present embodiment, the width W2 of the eye shield 10 is longer than the width W3 of the mask 2 even at the position where the width of the eye shield 10 is the narrowest (the lower end of the eye shield 10 in the present embodiment). It is said to be 17 cm or more. As a result, in the face guard 1 according to the present embodiment, as shown in FIG. 3, the entire mask 2 can be covered by the face guard 1, so that the inhalation of the virus from the side portion of the mask 2 or the like can be reduced. can. In the present embodiment, the width of the largest portion of the width of the eye shield 10 is 25 cm or more.

Openings 13 and 14 are formed on the left and right cheeks 11 and 12 of the eye shield 10, respectively. As shown in FIG. 2, the openings 13 and 14 are openings for passing the strings 21 and 22 of the mask 2. In the present embodiment, the vertical length L2 of the openings 13 and 14 is shorter than the vertical length L3 of the mask 2 (or the upper string 21 near the side edges 23 and 24 of the mask 2). The openings 13 and 14 are formed so as to be shorter than the distance between the lower string 22 and the lower string 22).

The vertical length L2 of the openings 13 and 14 is not particularly limited, but may be ½ or more and 9/10 or less of the vertical length L3 of the side edges 23 and 24 of the mask 2. preferable. For example, when the vertical length L2 of the mask 2 is 10 to 9 cm, the vertical length L1 of the opening 20 can be 7 to 5 cm. As a result, when the user hangs the string of the mask 2 on the ear, the upper string 21 of the mask 2 pushes up the openings 13 and 14 upward due to the tension of the strings 21 and 22 of the mask 2, and the mask 2 The face guard 1 can be supported by the mask 2 by the lower string 22 pushing down the openings 13 and 14 downward. Further, it is preferable that the openings 13 and 14 are configured such that the opening width of the central portion in the longitudinal direction is wider than the opening width of the end portion in the longitudinal direction. This is because it becomes easy to insert the strings 21 and 22 by making the opening width of the central portion wide. In the present embodiment, the openings 13 and 14 are substantially triangular, but the present invention is not limited to this, and may be, for example, a rhombus.

Further, when the face guard 1 is attached in combination with the mask 2, as shown in FIGS. 3 and 4, the mask 2 is arranged inside the face guard 1, and the strings 21 and 22 of the mask 2 are placed in the openings 13 and. It is used by passing it from the inside to the outside of 14. Therefore, the cheeks 11 and 12 on the side edges 11A and 12A of the openings 13 and 14 are pressed from the outside to the inside (the face side of the user) by the strings 21 and 22 of the mask 2, and the face guard. The side edges 11A and 12A of 1 can be brought into close contact with the edge of the user's face.

The eye shield 10 (face guard 1) is formed with cutouts 16 at positions corresponding to the user's mouth and nose so that the face guard 1 does not cover the user's mouth and nose. By forming the notch portion 16, it is possible to prevent the face guard 1 from fogging due to the breath of the user, and the lower edge portion of the eye shield 10 which is the innermost part of the notch portion 16 of the face guard 1 is formed. Since it functions as a nose pad 15 that supports the user's nose portion, the face guard 1 can be supported more firmly. In addition, in order to improve the wearability, a detachable nose pad may be provided on the nose pad 15.

Next, a method of manufacturing the face guard 1 according to the present embodiment will be described. In the present embodiment, first, a boardon-processed material is prepared on a sheet of highly transparent polypropylene resin (for example, a thickness of 0.2 mm). Then, the eye shield 10 is cut out from the sheet using a mold. At the same time that the eye shield 10 is cut out, the openings 13 and 14 are also cut out. As a result, the face guard 1 according to the first embodiment can be manufactured. As described above, since the face guard 1 according to the present embodiment can be manufactured by only one punching step, it can be manufactured easily and at low cost.

Subsequently, a method of attaching the face guard 1 according to the present embodiment will be described. First, as shown in FIG. 2, the face guard 1 is arranged so as to overlap a part of the mask 2, and the strings 21 and 22 of the mask 2 are faced from the inside (face side) of the face guard 1 to the outside. Pass the openings 13 and 14 of the guard 1. Then, by hanging the strings 21 and 22 of the mask 2 on the user's ear as they are, the face guard 1 can be attached together with the mask 2 as shown in FIGS. 3 and 4.

As described above, the face guard 1 according to the first embodiment is a face guard used in combination with the mask 2, through which the eye shield 10 made of transparent resin and the strings 21 and 22 of the mask 2 are passed. Therefore, the eye shield 10 has a pair of openings 13 and 14 provided on both the left and right cheek portions 11 and 12, and the user can use the mask 2 in a state where the mask string is passed through the openings 13 and 14. By installing, it becomes possible to install. As described above, in the face guard 1 according to the present embodiment, since the mask 2 can be attached only by passing the strings 21 and 22 of the mask 2 through the openings 13 and 14 and attaching the mask 2, the face guard 1 can be easily used. Can be done. Further, since the mask 2 has a structure in which the cheeks 11 and 12 are pressed against the user's cheeks by the strings 21 and 22 and fixed, there is no possibility of falling unless the strings 21 and 22 come off the ears. Moreover, since the structure is adopted in which the strings 21 and 22 are passed through the openings 13 and 14, even if the openings 13 and 14 are used repeatedly, there is no risk of deterioration of adhesion like a hook-and-loop fastener or an adhesive, and it is hygienic. ..

Further, since the side edges 11A and 12A of the face guard 1 have a length L1 of 13 cm or more in the vertical direction, it is possible to cover both the periphery of the user's eyes and the periphery of the mouth (around the mask 2). Further, since the face guard 1 according to the present embodiment has notches 15 at positions corresponding to the mouth and nose of the user, it is possible to prevent the face guard 1 from becoming cloudy due to the breathing of the user. In addition, since the face guard 1 according to the present embodiment is composed of the eye shield 10 which is a single component, it is not necessary to assemble a plurality of components and it can be easily manufactured.

Further, in the face guard 1 according to the present embodiment, the vertical length L2 of the openings 13 and 14 is shorter than the vertical length L3 of the side edges 23 and 24 of the mask 2 (or the mask 2). (Because it is shorter than the distance between the upper string 21 and the lower string 22 at the side edges 23 and 24 of the mask 2), the tension of the upper string 21 and the lower string 22 of the mask 2 allows the mask 2 to properly support the face guard 1. It is possible. Further, in the above-mentioned face guard 1, when the face guard 1 is used in combination with the mask 2, the widths W1 and W2 of the face guard are longer than the length W3 in the left-right direction of the mask, so that the mask is masked by the face guard 1. The entire 2 can be covered, and suction of viruses and the like from the left and right sides of the mask 2 can be prevented.
