Utility Model Registration No. 3153844 Japanese Unexamined Patent Publication No. 9-224733 Japanese Unexamined Patent Publication No. 61-179313

By the way, since the full face mask of Patent Document 1 has a skeleton that covers the face and the head, there is a problem that there is a strong sense of discomfort when worn. Therefore, as in

Patent Documents

2 and 3, it is conceivable to use a full face mask capable of covering the entire face and head with a highly breathable cloth material without providing a framework. In

Patent Documents

2 and 3, since the opening is provided with a rubber cord, the opening can be easily expanded and attached by extending the elastic cord at the time of attachment, and the opening is contracted after the attachment. It is possible to keep the mask from coming off.

However, in the case of

Patent Documents

2 and 3, since the rubber cord of the mask in the worn state is arranged so as to surround the wearer's neck, for example, when the mask is unexpectedly pulled, it wraps around the neck. It may cause a feeling of strangeness.

The present disclosure has been made in view of such a point, and an object thereof is to reduce discomfort when a part is pulled while making it possible to easily wear a mask covering the entire face and head. There is.

In order to achieve the above object, the present disclosure is made of a breathable and translucent cloth material, and includes a bag-shaped main body portion that covers the face and head above the neck of the wearer. It is a mask that allows the outside to be seen through the main body, and around the opening through which the wearer's neck is inserted in the bag-shaped main body, the head is reduced in diameter from the neck. A stretchable rubber that expands the diameter so that the portion can be inserted is provided, and the rubber is characterized in that a part of the opening in the circumferential direction is discontinuous.

According to this configuration, when a force is applied in the direction of widening the opening, the rubber stretches, which causes the opening to expand in diameter, so that the face and head can be inserted into the opening. When the face and head are completely inserted into the bag-shaped body, the opening reaches the neck, the rubber shrinks and the opening becomes a diameter-reduced state, so the mask is difficult to remove from the wearer, and the mask once worn is, for example. It is possible to prevent it from falling off naturally while sleeping or unintentionally removing it by yourself.

Also, assuming that the bag-shaped main body is pulled unexpectedly with the mask attached, a force may act in the direction of stretching the rubber. Since a part of this rubber in the circumferential direction is not connected and is discontinuous, the discontinuous part of the rubber opens. This prevents the rubber from wrapping around the neck.

The second disclosure is that the rubber is located on the anterior side of the wearer's neck and is continuous from left to right, and is located on the posterior side of the wearer's neck and is continuous from left to right. It is characterized in that the front rubber and the rear rubber are discontinuous, including the side rubber.

According to this configuration, discontinuous parts of rubber are arranged on the left side and the right side of the wearer, respectively. Therefore, no matter which direction the bag-shaped main body is unexpectedly pulled, the rubber will not wrap around the neck.

The third disclosure is characterized in that the bag-shaped main body portion is provided with a weakened portion extending upward from a portion corresponding to the discontinuous portion of the rubber.

According to this configuration, when the discontinuous part of the rubber opens, the weakened part of the bag-shaped main body breaks. Since the weakened portion extends upward of the bag-shaped main body portion, the bag-shaped main body portion is continuously broken upward from the opening, and the bag-shaped main body portion can be prevented from wrapping around the neck.

According to the present disclosure, a rubber having a discontinuous portion is provided around the opening of the bag-shaped main body portion, and a weakening portion is provided so as to correspond to the discontinuous portion of the rubber, so that the bag-shaped main body portion is pulled. It is possible to reduce the feeling of strangeness at the time.

FIG. 1 is a side view showing a wearing state of a mask according to an embodiment of the present invention. FIG. 2 is a view of the mask viewed from below. FIG. 3 is a view corresponding to FIG. 1 according to a modified example of the embodiment.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is essentially merely an example and is not intended to limit the present invention, its application or its use.

FIG. 1 is a side view showing a wearing state of the mask 1 according to the embodiment of the present invention. The mask 1 includes a bag-shaped main body 2 and a rubber 3. The bag-shaped main body 2 is made of a breathable and translucent cloth material, and is formed so as to be able to cover the wearer's neck and above, that is, the face and head. As the cloth material constituting the bag-shaped main body 2, various cloth materials can be used, and examples thereof include non-woven fabrics. The non-woven fabric is preferably one having filter performance like the cloth material used for conventional general masks, and has high filtration performance that hardly allows various allergens, pollen, dust, dust, viruses, etc. to permeate, for example. ing. Further, the cloth material may have an adsorptive property for adsorbing a virus or the like.

As the cloth material constituting the bag-shaped main body 2, a stretchable material or a flexible material can be used. By using a cloth material having elasticity and flexibility, for example, the bag-shaped main body 2 can be easily attached and detached when the mask 1 is attached and detached, and the discomfort when worn can be reduced. .. The above-mentioned cloth material may be, for example, a cloth material used for covering hair in a food processing factory, a sanitary facility, or the like.

The cloth material constituting the bag-shaped main body 2 can be visually recognized from the inside to the outside. For example, a wearer wearing a mask 1 can visually see the outside through the mask 1 outdoors in the daytime or indoors illuminated. As a result, it is possible to move, read a book, and watch TV while wearing the mask 1, and there is almost no hindrance to life. The degree of external visibility can be changed, for example, by the basis weight of the cloth material, the thickness of the cloth material, the degree of density of the fibers constituting the cloth material, etc. Can be selected.

At the lower part of the bag-shaped main body 2, an opening 2a for inserting the face and the head into the bag-shaped main body 2 is formed. Around the opening 2a, a stretchable rubber 3 is provided to change the diameter of the opening 2a from a reduced diameter state that is smaller than that of the neck to an enlarged diameter state that allows the head to be inserted. A part of the rubber 3 in the circumferential direction of the opening 2a is discontinuous.

That is, the rubber 3 is located on the front side of the wearer's neck and is continuous from left to right as the first rubber 3a, and is located on the rear side of the wearer's neck and is continuous from left to right. It contains a rear rubber 3b as a second rubber to be used. The front rubber 3a is provided in a range from the left side to the front and the right side of the peripheral edge of the opening 2a of the bag-shaped main body 2. Further, the rear rubber 3b is provided in a range from the left side portion to the rear side portion and the right side portion in the peripheral portion of the opening portion 2a of the bag-shaped main body portion 2. The lengths of the front rubber 3a and the rear rubber 3b are such that the diameter of the opening 2a is smaller than that of the neck in the free state, that is, the circumference of the opening 2a is shorter than the circumference of the neck. It is set. The front rubber 3a and the rear rubber 3b may be sewn to the peripheral edge of the opening 2a, or may be attached by adhesion or the like. In the free state, the opening 2a may be almost crushed.

When a force is applied to the opening 2a in the diameter-expanding direction, the front rubber 3a and the rear rubber 3b are stretched to expand the diameter of the opening 2a. At this time, the elongation rates of the front rubber 3a and the rear rubber 3b are increased so that the diameter of the opening 2a is larger than that of the head, that is, the circumference of the opening 2a is longer than the circumference of the head. It is set. The front rubber 3a and the rear rubber 3b can be made of, for example, a string-shaped rubber.

The left end of the front rubber 3a and the left end of the rear rubber 3b are not connected. Further, the right end portion of the front rubber 3a and the right end portion of the rear rubber 3b are not connected. Therefore, the left end of the front rubber 3a and the left end of the rear rubber 3b are discontinuous, and the right end of the front rubber 3a and the right end of the rear rubber 3b are discontinuous. As a result, two discontinuous portions of the rubber 3 are provided, and are arranged on the left side and the right side of the mask 1, respectively. The discontinuous portion of the rubber 3 may be provided on the front side and the rear side. Further, three or more discontinuous portions of the rubber 3 may be provided. Further, the position where the discontinuous portion of the rubber 3 is provided is not particularly limited, and may be anywhere in the circumferential direction of the opening 2a. Further, the rubber 3 may include a left rubber (not shown) that is continuous from the front to the left side and the back, and a right rubber (not shown) that is continuous from the front to the right side and the back. In this case, the front end of the left rubber and the front end of the right rubber are not connected, and the rear end of the left rubber and the rear end of the right rubber are not connected.

Note that the rubber 3 may have only one discontinuous portion, and in this case, only a part of the rubber 3 in the circumferential direction is not connected. The discontinuous portion of the rubber 3 may be only the left side, only the right side, only the front side, or only the rear side.

The bag-shaped main body 2 is provided with a left side weakening part 2b and a right side weakening part 2c. The left side weakening portion 2b and the right side weakening portion 2c extend upward from the portion corresponding to the discontinuous portion of the rubber 3. Specifically, the left weakening portion 2b reaches the vertical intermediate portion of the bag-shaped main body portion 2 starting from between the left end portion of the front rubber 3a and the left end portion of the rear rubber 3b, or near the left end portion thereof. ing. The right side weakening portion 2c reaches the vertical intermediate portion of the bag-shaped main body portion 2 starting from between the right end portion of the front rubber 3a and the right end portion of the rear rubber 3b, or near the right end portion thereof. The left side weakening portion 2b and the right side weakening portion 2c are portions that break with a smaller force than other portions, such as a portion where perforations are formed. The left side weakening portion 2b and the right side weakening portion 2c can be formed of a portion in which perforations are formed, may be a portion in which a large number of small holes are formed at predetermined intervals, or a large number of thin-walled portions. May be a portion formed at a predetermined interval, or may be a fragile portion.

A front weakening portion 2d extending in the left-right direction is formed in the vertical middle portion on the front side of the bag-shaped main body portion 2. The formation position of the anterior weakening portion 2d is preferably below the eyes of the wearer and above the nose, but may be above the eyes, below the nose, or below the mouth. It may be. The right end of the anterior weakening portion 2d is positioned near the wearer's right cheek or right ear. Further, the left end portion of the front weakening portion 2d is positioned near the left cheek and the left ear of the wearer. The front weakening portion 2d may be continuous in the left-right direction or may be intermittent. The front weakening portion 2d can be configured in the same manner as the left weakening portion 2b. The front weakening portion 2d may be provided as needed, or may be omitted.

A highly filterable cloth material 4 having higher filtration performance than the cloth material constituting the bag-shaped main body portion 2 can be provided on the front side of the bag-shaped main body portion 2. The range in which the highly filterable cloth material 4 is provided is a portion extending from the nose to the mouth of the wearer, and can be a range in which the nose and the mouth can be completely covered. As a result, when the wearer breathes, the air that has passed through the highly filterable cloth material 4 can be sucked, and the air exhaled from the wearer passes through the highly filterable cloth material 4 and flows out to the outside. The highly filterable cloth material 4 is not essential and may be omitted.

Further, a transparent portion (not shown) may be provided on the front side of the bag-shaped main body portion 2 so as to correspond to the height of the wearer's eyes. By providing the transparent portion, the wearer can clearly see the outside through the transparent portion. The transparent portion may be colorless and transparent, or may be a lightly colored transparent portion. The transparent portion may be made of a member separate from the bag-shaped main body portion 2. In this case, the eye-high portion of the bag-shaped main body 2 may be broken to provide a gap that allows the outside to be visually recognized, and the transparent portion may be attached to the bag-shaped main body 2 so as to close the gap. ..

Further, on the bag-shaped main body 2, a display indicating the wearer's symptom may be written in characters or the like. For example, in the case of pollinosis, "pollen allergy" is described in the bag-shaped main body 2, and in the case of a cold, "cold" is described in the bag-shaped main body 2.

The bag-shaped main body 2 can hold, for example, an aroma oil composed of essential oils and essential oils. As a result, it is possible to enhance the sleep-rest effect when sleeping while wearing the mask 1. The aroma oil may be impregnated into the bag-shaped main body 2, or may be supported on a carrier and attached to the bag-shaped main body 2.

Various vitamin preparations, hyaluronic acid, moisturizing ingredients, etc. can be retained in the bag-shaped main body 2. These components may be impregnated into the bag-shaped main body 2, or may be supported on a carrier and attached to the bag-shaped main body 2, but it is preferable that these components are in contact with the wearer's face or head. .. As a result, the beauty effect of the skin and the beauty effect of the hair are enhanced.

Next, the procedure for attaching the mask 1 will be described. For example, when a hand is put into the opening 2a and a force is applied in the direction of expanding the opening 2a, the rubber 3 is stretched, whereby the opening 2a is expanded in diameter. While expanding the diameter of the opening 2a, the face and the head are inserted into the opening 2a. When the face and head are completely inserted into the bag-shaped main body 2, the opening 2a reaches the neck. Then, the rubber 3 shrinks and the opening 2a is in a reduced diameter state, so that the mask 1 is difficult to be removed from the wearer, and the mask once worn may fall off naturally while sleeping, or may be unknowingly removed by oneself. It can be prevented from being lost.

Mask 1 is breathable as a whole, so you will hardly feel stuffy. In addition, if the wearer has acne, facial or head injuries, or infected wounds, the affected area may be coated with a drug to sleep. In this case, by wearing the mask 1, the drug does not adhere to the bedding such as pillows and futons, the effect of the drug can be obtained for a long time, and the bedding can be prevented from becoming dirty. Further, by wearing the mask 1, it becomes difficult for sebum and bacteria adhering to the bedding to come into contact with the infected wound such as acne, so that the deterioration of the infected wound can be suppressed.

When the wearer breathes while wearing the mask 1, the exhaled breath fills the inside of the mask 1 and then flows out to the outside. Since the exhaled breath contains water vapor, the humidifying effect of the exhaled breath can suppress the dryness of the skin.

In addition, when an infection such as a cold or influenza occurs, it is necessary to isolate it in the home, facility, or hospital. Is less likely to scatter around. As a result, the possibility of infecting another person is significantly reduced, so that it is not necessary to isolate the infected person, which is very effective in terms of mental health. In particular, patients with droplet infections such as SARS (Severe Acute Respiratory Syndrome), coronavirus, influenza, etc. are placed in the same space with others, for example, in hospital rooms, waiting rooms, treatment rooms, various facilities, airplanes, buses, trains, etc. The spread of the infection can be minimized without special isolation. This is especially effective when the number of infected people increases significantly.

In addition, when pollen is scattered or when there is an animal allergy, the probability of contact with an allergen can be significantly reduced by wearing the mask 1 according to the present embodiment at bedtime. In addition, since the eyes are covered with the mask 1, it is possible to prevent the eyes and the like from being suddenly irritated by the fingers to which the allergen is attached, which also prevents eye diseases such as allergic conjunctivitis.

The size and shape of the mask 1 can be changed arbitrarily according to the wearer. For example, the shape shown in FIG. 1 is mainly suitable for men or women with short hair. For example, the modified example of the embodiment shown in FIG. 3 has a shape suitable for a woman with long hair, and a hair accommodating portion 2e is provided at the rear portion of the bag-shaped main body portion 2. The hair accommodating portion 2e is a portion capable of accommodating the wearer's hair, and is formed so as to bulge downward from the opening 2a. The size, position, and shape of the hair accommodating portion 2e can be changed according to the hairstyle.

In addition, a mask 1 having a size suitable for a child can be used, and masks 1 for infants, children, and adults can be prepared. For example, in the case of the mask 1 for infants and children, it is preferable that the left weakening portion 2b, the right weakening portion 2c, and the front weakening portion 2d are more easily broken than those for adults.

Assuming that the bag-shaped main body 2 is unexpectedly pulled while the mask 1 is attached, a force may act in the direction of stretching the rubber 3. Since a part of the rubber 3 in the circumferential direction is not connected and is discontinuous, the discontinuous portion of the rubber 3 is opened. Specifically, the distance between the right end of the front rubber 3a and the right end of the rear rubber 3b is widened, and the distance between the left end of the front rubber 3a and the left end of the rear rubber 3b is widened. When the distance between the right end of the front rubber 3a and the right end of the rear rubber 3b is widened, a breaking force acts on the lower end of the left weakening portion 2b of the bag-shaped main body 2, and this breaking force acts on the left weakening portion. 2b breaks. The right weakened portion 2c also breaks in the same manner. As a result, the rubber 3 and the bag-shaped main body 2 do not wrap around the neck, so that a sense of discomfort is reduced. Depending on how the force is applied, only one of the left side weakening portion 2b and the right side weakening portion 2c may be broken.

In addition, if you want to improve the visibility or feel stuffy while wearing the mask 1, you can break the front weakening part 2d. When breaking the front weakening portion 2d, the wearer may manually grasp and pull the vicinity of the front weakening portion 2d of the bag-shaped main body portion 2, whereby the front weakening portion 2d is broken and the visibility is improved. As well as getting better, the suffocation is eliminated.

(Action and effect of the embodiment)
As described above, according to this embodiment, the front rubber 3a and the rear rubber 3b are provided around the opening 2a of the bag-shaped main body 2, so as to correspond to the discontinuous portions of the

rubbers

3a and 3b. Since the weakening

portions

2b and 2c are provided, it is possible to reduce a sense of discomfort when the bag-shaped main body portion 2 is pulled.

The above embodiment is merely an example in every respect and should not be construed in a limited way. Furthermore, all modifications and modifications that fall within the equivalent scope of the claims are within the scope of the present invention.

As described above, the mask according to the present invention can be used by, for example, a healthy person in daily life, as well as a patient with various infectious diseases, an allergic patient, and the like.
