Description

The present invention relates to a mask capable of exposing the mouth when eating and drinking, and particularly to a mask capable of confirming the mouth when eating and drinking.

In recent years, masks have been used for the purpose of preventing droplet infection of infectious diseases. Such masks are used for various purposes such as measures against droplet infection of infectious diseases (that is, measures against viruses), measures against pollinosis, measures against colds, dust prevention, cold protection, etc., for industrial use, medical use, household use, etc. It is widely used in the applications of.

However, since the mask covers the wearer's mouth, it is not possible to eat or drink while wearing the mask. Therefore, the mask must be removed when eating or drinking. On the other hand, it is recommended to wear the mask during conversation to prevent the spread of droplets. Therefore, it was troublesome to put on and take off the mask when eating and drinking.

Therefore, in the past, studies have been conducted to reduce the time and effort required to put on and take off the mask when eating and drinking. For example, in Patent Document 1 (Utility Model Registration No. 3228351), the wearer's mouth can be easily exposed and covered without removing the ear hook and the mask body, and the mouth is exposed. Masks that make it easy to eat and drink when in a state have been proposed. That is, in this document, the mask body covering the wearer's mouth and nose and their surroundings includes an opening provided in a substantially central portion and a closing portion provided on the surface of the mask body to open and close the opening. We propose a mask provided with a core material at least a part of the peripheral edge of the opening.

Further, in Patent Document 2 (Utility Model Registration No. 3229085), the user's nose and the periphery of the mouth are covered as a mask that can be eaten and eaten while being worn and can prevent droplets from coming out of the mouth as much as possible. A mask having a linear shape-retaining member that also serves as a weight provided at the lower end of the mask body has been proposed.

Utility Model Registration No. 3228351 Utility Model Registration No. 3229085

As described above, some masks have been proposed in which only the mouth is exposed from the opening when the mask is worn. However, in the conventional mask, the obstruction covering the opening is opened laterally or upward, so that the obstruction is an obstacle to eating and drinking when the mouth is exposed. Therefore, one of the problems of the present invention is to provide a mask that allows eating and drinking while checking the mouth even when the mouth is exposed when the mask is worn.

Further, since the mask that exposes only the mouth, which has been proposed in the past, is configured to close the opening formed in the mask body with a closing portion, a gap is created between the mask body and the closing portion. The possibility that droplets would diffuse from this gap could not be denied. Therefore, one of the other problems of the present invention is to provide a mask that does not cause such a gap, or even if it does occur, can prevent the diffusion of droplets.

Furthermore, the previously proposed mask that exposes only the mouth has an opening and a blockage in the mask body through which inspiration and exhalation during breathing pass, so if the mask body becomes dirty, the mask itself should be replaced. I had to do it. Therefore, in the present invention, one of another problems is to provide a mask that can be used for a long period of time by making it possible to replace only the mask body through which inspiration and exhalation during respiration pass.

In order to solve at least one of the above problems, in the present invention, the screen member covering the wearer's mouth and nostrils is rolled downward (or folded back; the same applies hereinafter) to expose the mouth and nostrils. Provide such a mask.

That is, the mask according to the present invention includes a frame portion formed as a frame body that exposes at least the wearer's mouth portion, a pair of left and right string-shaped mounting portions that hold the frame portion on the wearer's face, and the above. It is a size that covers the wearer's mouth and nostrils, and is composed of a screen member whose upper end side is detachably provided with respect to the frame part, and the screen member has its upper end side rolled downward. In the state, it is configured to expose the wearer's mouth.

The string-shaped attachment portion may be a string body that is tied on the back of the head side of the wearer in addition to the ear hook string. Further, the frame portion includes an upper frame extending across the back of the nose (nasal muscle) of the wearer, a lower frame extending across the lower side of the wearer's mouth, and left and right of the upper frame and the lower frame. It can be formed by a connecting portion that connects both sides. The frame portion is preferably formed by using a cloth such as a non-woven fabric or a cloth, but may be formed by another material such as a resin.

Further, it is desirable that the upper edge portion of the screen member is detachably provided on the upper frame and the lower edge portion is detachably provided on the lower frame. If the upper edge portion and the lower edge portion of the screen member are made detachable from the frame portion and the side edge portion of the screen member is left free without being attached to the frame portion, the entire screen member can be attached to the frame portion. It is removable and can be replaced.

The screen member can be attached to the frame portion by using double-sided tape, or can be detachably attached to the frame portion by using an adhesive (including an adhesive gel), a hook-and-loop fastener, a hook, or a clip. When it is not necessary to replace the screen member, the lower edge portion of the screen member can be integrated with the lower frame by suturing, an adhesive or the like. It is also desirable that the upper edge portion of the screen member is detachably provided on the upper frame only on the left and right ends. By attaching at two points on the left and right, it is possible to eliminate the distortion when deformed along the back of the nose (nasal muscle).

It is desirable that the side edge portion of the screen member is configured to be in contact with the wearer's face, particularly the cheek portion, when worn. Therefore, the connecting portion connecting the upper frame and the left and right sides of the lower frame is formed in a string shape or a thin band shape, and the side edge portion of the screen member is in direct contact with the wearer's face (particularly the cheek portion). It is desirable to configure it as follows. By bringing the side edge portion of the screen member into direct contact with the wearer's face (particularly the cheek portion), the screen member can be brought into close contact with the wearer's face, and the occurrence of gaps can be avoided as much as possible.

Further, in the mask according to the present invention, it is desirable that the upper edge portion of the screen member is provided with a wire rod that can be plastically deformed along the upper edge portion, and in particular, the upper edge portion of the upper frame and the screen member. It is desirable that both the upper edges are provided with plastically deformable wires along the upper edges. However, the upper edge of the upper frame may not be provided with a plastically deformable wire, and the upper edge of the screen member may be provided with a plastically deformable wire. By providing at least a plastically deformable wire rod on the upper edge of the screen member, the screen member can be brought into close contact with the wearer's face and a gap between the two can be eliminated.

The mask according to the present invention includes a frame portion formed as a frame body that exposes at least the wearer's mouth, a pair of left and right string-shaped mounting portions that hold the frame portion on the wearer's face, and the wearer. The screen member has a size that covers the mouth and nostrils of the screen, and the upper end side thereof is detachably provided with respect to the frame portion. The screen member is in a state where the upper end side is rolled downward. , It is configured to expose the wearer's mouth. That is, the wearer's mouth and nostrils are exposed by rolling the screen member downward. As a result, even when the wearer eats and drinks, the rolled screen member can smoothly eat and drink while checking the mouth without obstructing the wearer's field of vision.

Further, a plastically deformable wire rod is provided along the upper edge portion of the screen member, and the side edge portion of the screen member is brought into direct contact with the wearer's face (particularly the cheek portion). The mask can be used so that there is no gap between it and the face, or even if it does occur, the spread of droplets can be prevented.

Further, when both the upper edge portion and the lower edge portion of the screen member are detachable from the frame portion, only the screen member through which inspiration and exhalation during respiration pass can be replaced, and the screen member can be used for a long period of time. It can be a mask that can be used.

Hereinafter, the mask 10 according to the present embodiment will be specifically described with reference to the drawings. FIG. 1 is (A) front exploded view, (B) front view, and (C) CC end view showing the mask 10 according to the first embodiment.

The mask 10 according to the first embodiment is composed of a holding member 20 including a frame portion 22 and a mounting portion 21, and a screen member 30 detachably provided on the front side of the holding member 20. .. The holding member 20 has a function of holding the screen member 30 in the vicinity of the wearer's mouth and nose, and the screen member 30 covers the vicinity of the wearer's mouth and nose to diffuse droplets. It can function as a filter that blocks suction.

In the present embodiment, the holding member 20 has a frame portion 22 formed as a frame body that exposes the wearer's mouth portion, and a pair of left and right string-shaped attachments that hold the frame portion 22 on the wearer's face. It is composed of a part 21. The frame portion 22 includes an upper frame 23 extending across the back of the nose (nasal muscle) of the wearer, a lower frame 25 extending across the lower side of the wearer's mouth, and the upper frame 23 and the lower side. It is composed of a connecting portion 24 that connects the left and right sides of the frame 25, respectively. The upper frame 23 and the lower frame 25 are formed in a band shape using a non-woven fabric, thereby improving the feel of the wearer. However, the upper frame 23 and the lower frame 25 can be formed by using a cloth such as a woven fabric or a knitted fabric, and further can be formed by using a resin such as a film. The upper frame 23 and the lower frame 25 are preferably formed in a strip shape having a width of 1 cm or more. This is to prevent the occurrence of gaps.

Further, in the present embodiment, the connecting portion 24 uses a rubber string (mask string). However, the connecting portion 24 may use a cloth such as a non-woven fabric, a woven cloth, and a knitted cloth. It is desirable that the connecting portion 24 is expandable and contractible. This is because the connecting portion 24 expands and contracts, so that the adhesion with the cheek portion of the wearer at the time of wearing can be improved. In particular, when the screen member 30 is rolled down as described later, the lower frame 25 is caught by the wearer's chin, and the wearability of the holding member can be improved. Therefore, the length of the connecting portion 24 is formed so that the vertical length (height) of the holding member 20 is shorter than the vertical length (height) of the screen member 30. .. This is to avoid the occurrence of a gap between the mask 10 and the cheek portion and improve the wearability of the holding member 20 by utilizing the elasticity of the connecting portion 24.

In particular, the holding member 20 according to the present embodiment is formed by cutting off the upper and lower central portions of a commercially available pleated (folded) non-woven fabric mask and connecting the left and right sides with a mask string. However, as shown in the second embodiment described later, the holding member 20 may be manufactured by using a cloth or the like.

The screen member 30 can be formed by using a material having a collection (filtration) ability suitable for the purpose, for example, a medical mask American standard defined by ASTM International (International Standardization and Standardization Organization) in the United States (American standard for medical use). Those with the desired collection (filtration) capacity can be used based on ASTM-F2100-19). In the present embodiment, the same filter portion (mask body portion) of a commercially available mask as a household mask or a medical mask can be used.

The screen member 30 is formed in a size that covers at least the wearer's mouth and nostrils, and a detachable member 40 that is detachably attached to the frame portion 22 of the holding member 20 is attached to the upper edge portion. It is provided. As the detachable member 40, it is desirable to use a member capable of ensuring a plurality of detachable operations between the screen member 30 and the frame portion 22, for example, a double-sided tape, an adhesive (including a gel-like adhesive), a hook-and-loop fastener, and a hook. Etc. are desirable. In particular, in the present embodiment, double-sided tape is used as the detachable member 40. This is because it is easy to install and has durability to withstand multiple uses.

The screen member 30 has its lower edge attached to the lower frame 25 of the frame portion 22 of the holding member 20. In addition to integrating the two by suturing or gluing, the attachment / detachment member 40 is used to attach / detach the lower edge portion of the screen member 30 to the lower frame 25 (that is, the frame portion 22). It can be provided freely. When the lower edge portion of the screen member 30 is also detachably provided, the screen itself can be removed from the holding member 20, and when it becomes dirty due to use, only the holding member 20 can be replaced. The mask 10 is realized. In particular, since the mask 10 according to the present embodiment is suitable for use when eating and drinking, when the screen member 30 becomes dirty during eating and drinking, the screen member 30 is immediately replaced with a new one. be able to.

A wire rod 50 that is plastically deformable is provided on the upper edge portion of the screen member 30 so as to be along the upper edge portion. The wire rod 50 is a resin wire having shape-retaining property (property to maintain a bent shape), may be a metal wire such as copper or aluminum, and is a paper band formed to a thickness having shape-retaining property. It may be. By providing the wire rod 50, the upper side of the screen member 30 can be bent so as to cross the wearer's nose, and a gap between the screen member 30 and the wearer's face can be eliminated.

In particular, in the mask 10 according to the present embodiment, the plastically deformable wire rod 50 is also provided on the upper edge portion of the frame portion 22. Therefore, the wire rod 50 of the upper frame 23 of the frame portion 22 is in close contact with the wearer, and the wire rod 50 provided on the screen member 30 can prevent the generation of a gap between the mask 10 and the wearer. it can. However, the plastically deformable wire rod 50 may be provided at least on the upper edge of the screen member 30. This is because the wire rod 50 can suppress the frame portion 22 (particularly the upper frame 23) existing on the face side of the wearer. Further, by providing the wire rod 50 on the upper edge side of the screen member 30, when the screen member 30 is rolled downward, it can be held under the chin. That is, the shape of the screen member 30 wound downward is held by the wire rod 50, and can be held under the wearer's chin. At this time, the detachable member 40 provided on the screen member 30 can also function to hold the screen member 30 rolled under the chin. That is, by attaching the detachable member 40 to the lower frame 25 or the like, the screen member 30 expands below the chin, and it is possible to avoid itself causing trouble in eating and drinking.

As shown in FIG. 1B, the holding member 20 and the screen member 30 configured as described above have the screen member 30 present on the front side of the holding member 20 so that the upper and lower edges of the holding member 20 and the screen member 30 are aligned with each other. Then, they are connected by the detachable member 40. At this time, since the vertical length (height) of the holding member 20 is shorter than the vertical length (height) of the screen member 30, as shown in FIG. 1C, the screen is formed at the side edge portion. The member 30 is curved so as to project toward the front side. As a result, the screen member 30 can be curved and deformed along the wearer's face in the vertical direction, and the side edge portion is brought into close contact with the wearer's face (cheek portion) by the extension of the connecting portion 24. Can be done. As a result, the mask 10 that does not create a gap with the wearer is realized.

FIG. 2 shows (A) an exploded front view and (B) a front view showing the mask 10 according to the second embodiment. In particular, in the mask 10 according to this embodiment, the frame portion 22 of the holding member 20 is formed as a rectangular frame made of cloth, and the outer edge shape (outer contour shape) of the frame portion 22 is the screen member 30. It is formed in the same shape as the outline shape of. That is, the vertical length of the frame portion 22 is formed to be substantially the same as the vertical length of the screen member 30. A string-shaped mounting portion 21 is provided on the frame portion 22 to form the holding member 20. The screen member 30 is the same as that of the first embodiment.

In the mask 10 according to the present embodiment, the frame portion 22 is not provided with the plastically deformable wire rod 50. However, the wire rod 50 provided on the upper edge of the screen member 30 can be molded so as not to create a gap with the wearer.

The screen member 30 is provided on the front side of the holding member 20 configured as described above. In particular, the screen member 30 is integrated with the holding member 20 by suturing or adhering the lower edge side thereof, while the upper edge portion thereof is detachably attached to the upper frame 23 by the detachable member 40. It is provided. As a result, the mask 10 according to this embodiment also has the upper end side of the screen member 30 turned downward when eating and drinking when worn, so that the mask 10 is present in the lower part of the chin of the wearer. It is possible to easily check the mouth when eating and drinking.
