Description

  The present invention relates to a sanitary mask for preventing common cold and influenza infection.

Common colds and influenza infections occur when viruses or bacteria enter the respiratory tract. For this reason, masks worn to prevent infections should cover the mouth and nostrils leading to the respiratory tract with gauze or non-woven fabric so that the particles such as viruses that scatter from coughs and sneezes are not directly inflamed (prevention of splash infection) In addition, we try not to inhale fine particles floating in the air (air infection).
In recent sanitary masks, various developments have been made to bring the peripheral edge of the mask into close contact with the face so that viruses and the like do not enter the body as much as possible. For example, a plastic deformation material is disposed on the back of the nose of the mask body, or a three-dimensional shape corresponding to the face shape is used to prevent a gap between the mask peripheral portion and the face (for example, a patent) Reference 1).

Utility Model Registration No. 3100600

By the way, even if there is a space between the mask body and the mouth or nostril, for example, the mask has a three-dimensional shape, because it is made so that there is no gap between the mask periphery and the face as much as possible. It is unavoidable that suffocation remains.
For this reason, if you understand the importance of masks, you can endure some of the shortness of breath, but if you do not understand the importance of masks, such as infants and demented elderly people, you can endure the shortness of breath. In many cases, the mask is peeled off.

Therefore, for infants etc., it is difficult to prevent even airborne infections and even droplet infections, even if they can keep the airway humidity by wearing them for a short time with a mask. I do not get.
In addition to airborne infection and droplet infection, there are direct infections in which bacteria and other attached hands touch the mouth and nose as well as common infections and influenza. However, for infants, etc., it is inevitable that the hand touches the mouth or nose by putting a hand into the mask or peeling the mask as described above due to the difficulty of breathing when wearing the mask. For this reason, there is a risk that a virus or the like may enter.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a sanitary mask that can effectively prevent common colds, influenza, etc. even if the person cannot understand the importance of the mask. .

According to the first aspect of the present invention, there is provided a mask main body that covers a wearer's mouth and nostril, and a pair of left and right ears that are locked to the ear to hold the mask main body on the wearer's face. An infant hygiene mask comprising a hanging portion, wherein the mask body bulges forward so as to form an inner space between the mask body and the mouth and nostril when worn; A rim that protrudes in a hook shape with respect to the bulging portion and maintains a shape even when an external force is applied, and the rim portion is worn along the rim of the bulging portion. A plurality of convex portions projecting toward the person side are formed, and an air passage connecting the inner space and the outer space between the plurality of convex portions and in the lower half region of the jaw side A portion is formed, and the convex portion has a region that hits the lower half cheek compared to the upper half region. Is solved by infants hygiene mask is greatly projected into the wearer's side.

According to the first aspect of the invention, the mask body covering the wearer's mouth and nostril bulges forward so as to form an inner space between the mask body and the mouth and nostril when worn. Since the bulging portion is provided, the mask main body is not in close contact with the mouth or nostril, and breathing is facilitated.
And since the peripheral part of this mask main body is provided with the some convex part which protruded in the wearer side along the peripheral part of the bulging part, this convex part played the role of the rib and the bulging part The shape can be maintained.
Furthermore, between each of the plurality of convex portions is an air passage portion that communicates the inner space and the outer space, breathing air can be taken in and out from the air passage portion. For this reason, the breathing difficulty felt by the wearer is greatly reduced, and even if the wearer does not understand the importance of the mask, there is a risk of putting his hand in the mask or peeling the mask. It can be effectively prevented.
Here, by providing this air passage portion, it becomes difficult to prevent air infection in which viruses or the like floating in the atmosphere enter the airway. However, the air passage portion is arranged on the peripheral portion protruding in a bowl shape with respect to the bulging portion (that is, outside the bulging portion covering the mouth and nostril), and a plurality of the peripheral portion protruding to the wearer side. Since it is arrange | positioned between each of these convex parts, it is located in the back side (wearer side) of a mask main body. Therefore, even if at least a splash due to an infected person's cough is blown from the front of the wearer, the splash can be prevented from directly entering the mouth or nostril.
From the above, if you analyze the behavior of those who cannot understand the importance of masks such as infants, you can not prevent airborne infections or even contact infections by removing the mask or putting your hand in the mask. The mask of the present invention that can prevent droplet infection and contact infection exhibits a particular wearing effect as compared with conventional masks.

  In addition, preferably, the air passage portion is arranged on the chin side when the outer space side is worn compared to the inner space side. For this reason, even if splashes, dust, etc. fall from the top or try to invade from the left and right, movement from the outer space side to the inner space side such as splashes can be avoided. Therefore, compared to the invention of claim 1 which mainly prevents splashes from the front, it is possible to more effectively prevent splash infection.

Preferably, the peripheral portion is formed so that the length in the longitudinal direction on the jaw side is larger than the length in the longitudinal direction on the back side of the nose .

Preferably , a pattern is represented on the surface of the bulging portion so that a region that substantially faces the nostril bulges further forward by making a crease. . Therefore, the shape of the bulging portion is maintained more strongly than the configuration of the first aspect due to the fold of the bulging portion. In addition, the pattern formed by the folds can attract the interest of, for example, infants and encourage the wearing of the mask. Furthermore, the breath exhaled in the bulging portion has a distance until it hits the inner surface of the bulging portion, and can reduce the breathing difficulty of infants mainly breathing from the nasal cavity.

  As mentioned above, according to this invention, even if it is a person who cannot understand the importance of a mask, the sanitary mask which can prevent a common cold, influenza, etc. effectively can be provided.

The perspective view which looked at the sanitary mask which concerns on embodiment of this invention from the back side. The perspective view which looked at the sanitary mask of FIG. 1 from the front side. The front view of the sanitary mask of FIG. 1 (note that the alternate long and short dash line is the face of the wearer when the sanitary mask is worn).

The figure showing the state by which the underside of the sanitary mask of FIG. The front view of the mask which concerns on the modification of embodiment of FIG.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these forms.
The sanitary mask 10 of FIGS. 1 to 4 (hereinafter simply referred to as “mask 10”) is a mask 10 intended for infants among those who cannot understand the importance of the mask. Intended for infants up to age. Infants at this time are at a time when the risk of suffocation is low even when the mask 10 is worn, and the significance of wearing the mask cannot be understood at all. Of course, the mask 10 may be used by a person over 3 years old.
In addition, the mask 10 is a mask for preventing infection that mainly prevents rhinovirus, coronavirus, influenza virus, bacteria, etc., which cause diseases such as common cold and influenza, from entering the body from the mouth and nostrils. It is. The mask 10 has a slight function of preventing the entry of harmful substances floating in the air, such as pollen and house dust, and is therefore distinguished from a work mask and the like and used as a sanitary mask.

As shown in FIGS. 3 and 4, the mask 10 has a mask body 12 that continuously covers the wearer's mouth M and nostril HL, and the mask body 12 to hold the mask body 12 on the wearer's face. It has a pair of left and right ear hooks 20 that are locked to the ear YE of the wearer.
The mask body 12 is a part mainly intended to capture viruses and bacteria harmful to the human body. The mask body 12 has a particle size of, for example, 5 except for a connecting part 19 with an ear hook part 20 described later. It is made of non-woven fabric that can capture up to about micron.
And the mask main body 12 has the bulging part 14 bulging ahead, and the peripheral part 16 arrange | positioned outside this bulging part 14 (XY direction of FIG. 3).

The bulging portion 14 is in a central area that occupies the approximate area of the mask body 12, and differs from a normal sanitary mask that covers up to the bottom of the chin, generally in the longitudinal direction Y from the back of the nose K to the chin groove Q. The area of the entire width of the area and the horizontal direction X is covered.
When the bulging portion 14 is worn, an inner space S1 is formed between the mouth M and the nostril HL so that the inner surface of the mask body 12 and the mouth M or the nostril HL do not come into contact with each other. It is easy.

The bulging portion 14 of the present embodiment is formed as follows particularly corresponding to an infant.
That is, as to how the bulging portion 14 bulges, the front view is generally elliptical as shown in FIGS. 3 and 4, corresponding to the face of an infant that is rounder than that of an adult. Or it swells to the extent which does not contact an inner surface, even if the nostril HL and the opening | mouth M are distribute | arranged inside.
In addition, the bulging portion 14 of the present embodiment is a laminated state in which a plurality of types of nonwoven fabrics are stacked, and the nonwoven fabric of polypropylene or polyester is molded on the front side so that the swelling is not easily crushed by external force. While making it high rigidity (hence, it does not have a stretching property and flexibility) and making the back side (wearer side) softer than the front side, it is improving the touch.

Further, in the bulging portion 14, a region 30 substantially facing the nostril HL bulges further forward, and the interval L between the nostril HL and the region 30 facing it is increased. In other words, the top of the bulging portion 14 is provided at a position that is biased downward from the center in the height direction so that a sufficient distance L can be secured for the breath that has come straight from the nostril HL to reach the inner surface of the bulging portion 14. (In the case of FIG. 4, the lower side further bulges out from the center in the height direction). Thereby, the breath exhaled in the bulging part 14 has a distance until it hits the inner surface of the bulging part 14, and the breathing difficulty can be reduced. In particular, since the infants of this age are mainly breathing from the nasal cavity, they have a shape that takes into account the breath exhaled from the nostril HL rather than the breath exhaled from the mouth.
Further, a pattern 28 is represented on the surface of the bulging portion 14. The symbol 28 of the present embodiment is a bear's face, but is not limited to this as long as it attracts the interest of infants, and may be a symbol of another animal or vehicle. Thereby, an infant's interest can be attracted and wearing of mask 10 can be urged.

The pattern 28 is formed by making a crease 15 so that the bulge of the bulging portion 14 is difficult to be crushed. This crease 15 is more preferably groove-shaped as shown in the outermost contour portion 15a of the pattern 28, so that even a baby who is likely to touch the mask 10 with his / her hand has a bulging portion. 14 is more difficult to collapse.
In the mask 10 of this embodiment, the contour portion 15a is grooved to enhance the function of maintaining the shape, and the mouth M and the nostril HL are within the range defined by the groove-shaped folds of the contour portion 15a. This is because the mask main body 12, the mouth M, and the nostril HL in the range of the contour portion 15a are more strongly prevented from closely contacting each other.

The peripheral edge portion 16 is provided on the entire outer periphery of the bulging portion 14, and as shown in FIG. 4, is formed into a flange-like shape protruding from the bulging portion 14, and when worn, It arrange | positions so that it may generally face with respect to a wearer's face. The peripheral edge portion 16 also captures viruses, bacteria, and the like harmful to the human body in the same manner as the bulging portion 14.
The peripheral edge portion 16 is formed by extending so that the edge of the bulging portion 14 protrudes in the vertical and horizontal directions. Like the bulging portion 14, the non-woven fabric is molded to have high rigidity and can be expanded and contracted. It is difficult to be deformed by an external force without having properties and flexibility. Further, the peripheral edge portion 16 is formed such that the length dimension W2 in the longitudinal direction Y on the jaw side is larger than the length dimension W1 in the longitudinal direction Y on the nose back K side. More specifically, as shown in FIG. 3, the peripheral edge portion 16 has a shape that protrudes to the outside of the XY plane when viewed from the front, and the protruding length dimension (the above W1 and W2 are also part of the dimension). ) Gradually increases from the nasal dorsal K side toward the chin side.

As shown in FIG. 3, such a peripheral edge portion 16 includes a connecting portion 19 to which the ear hooking portion 20 is connected by thermal welding, an adhesive, or the like on the left and right sides of the front view (up to four locations). Is provided.
The connecting portion 19 protrudes outward from the peripheral edge portion 16 and has lower rigidity and flexibility than the peripheral edge portion 16. Thereby, even if the infant plays by touching the ear hooking portion 20, the shape change of the peripheral edge portion 16 following the movement of the ear hooking portion 20 is prevented. Specifically, the connecting portion 19 is formed by a laminated non-woven fabric layer forming the peripheral edge portion 16 projecting outward in a tongue-like shape.
In addition, the outer periphery of the peripheral portion 16 is substantially similar to the outer shape of the bulging portion 14 in a front view except for the connecting portion 19.

A pair of left and right ear hooks 20 are provided to hold the mask main body 12 on the wearer's face, and are elastic members that exert elastic force in the longitudinal direction. As shown in FIG. By pulling diagonally upward (in the direction of arrow Q), the ear YE can be hung.
That is, the mask main body 12 does not have elasticity or flexibility in order to maintain its shape. Therefore, in order to easily wear the mask main body 12, an elastic force is applied only to the ear hooking portion 20. .
In addition, although what is called a rubber string is employ | adopted for the ear hook part 20 of this embodiment, if this elastic force is exhibited, this invention is not limited to this.
Further, the ear hooking portion 20 has an elastic force that does not extend until the infant passes through the head, for example, by pulling against the elastic force. Accordingly, it is possible to prevent an infant from accidentally spreading the ear hook 20 and covering it from the head.
The ear hooking portion 20 is connected to the surface side of the connecting portion 19 of the peripheral edge portion 16. Thereby, the hardened | cured site | parts, such as heat welding and an adhesive agent, do not hit skin.
Preferably, the connection force between the ear hooking portion 20 and the connecting portion 19 is a force that does not disconnect when the mask is normally worn. However, the connection force is such that the connection force is released when a certain amount of force is applied. It has become. Thereby, it can prevent beforehand that there is no unexpected event by tightening by use other than normal use.

The mask 10 of the present embodiment is configured to have the above characteristics, and further has the following characteristics.
First, the peripheral edge portion 16 has a convex portion 33 protruding toward the wearer along the peripheral edge 14 a of the bulging portion 14, and this convex portion 33 serves as a rib to maintain the shape of the bulging portion 14. doing.
In addition, the convex part 33 of this embodiment is contacting the peripheral edge 14a of the bulging part 14 without leaving a space | interval from the bulging part 14, For this reason, as shown in FIG. It is made to look like it bites into a wearer side rather than the flat part 16a of the peripheral part 16. FIG. The convex portion 33 has a groove shape when viewed from the front side, and is formed when the mask main body 12 is molded.
And this convex part 33 has the predetermined | prescribed height that substantially all of the front-end | tip part 33b closely_contact | adheres to a wearer's face, as FIG. 4 shows in the state worn normally.

A plurality of such convex portions 33 are formed. As shown in FIGS. 3 and 4, the convex portion 33-1 continuously provided on the upper half of the mask main body 12 and the lower half of the mask main body 12 are provided. Side protrusions 33-2 and 33-3.
When the lowermost convex portion 33-2 is worn, the lowermost convex portion 33-2 is disposed below the lower lip UL and up to the chin J to form a chin-side convex portion 33-2. And the front-end | tip part 33b of the chin side convex part 33-2 also has the height H2 which contacts the front surface of a face at the time of wear, and even if the mask 10 tries to pass up, the chin side convex part 33-2 is the lower lip UL. It can hit the lower slope and prevent it from slipping up. That is, when the mask 10 moves downward, the bulging portion 14 is locked to the nasal spine K, whereas when the mask 10 moves upward, it is not locked under the chin (a normal sanitary mask has a chin The mask 10 is not worn that way). Further, since the ear hooking portion 20 pulls up the mask main body 12 obliquely upward (Q direction in FIG. 4), the mask main body 12 is easy to move upward from below. Therefore, when the wearer's face is large, there is a possibility that the wearer tends to slip up, and this is prevented by the jaw-side convex portion 33-2 being locked to the lower slope of the lower lip UL.
In addition, the convex part 33-3 on both sides of the chin side convex part 33-2 is arrange | positioned in the lower part of a cheek substantially, and becomes the cheek lower convex part 33-3.

Here, when the mask 10 is worn, an air passage portion 35 that connects the inner space S <b> 1 and the outer space S <b> 2 is formed between a plurality of adjacent convex portions 33. In other words, the air passage portion 35 is formed so as to cut out the convex portions 33 provided on the entire circumference of the peripheral edge portion 16 in the thickness direction. As a result, as shown in FIG. 1, breathing air is taken in through the space surrounded by the back side (wearer side) of the flat portion 16a of the peripheral edge portion 16 and the side surface 33a where the adjacent convex portions 33 face each other. This can greatly reduce the wearer's breathlessness.
As shown in FIGS. 3 and 4, the air passage portion 35 is formed outside the bulging portion 14 that covers the mouth M and the nostril HL, and is further formed on the back side (wearer side) of the peripheral edge portion 16. Therefore, even if the infected person facing the wearer coughs, the splash does not hit the front surface of the bulging portion 14 or the peripheral portion 16 and enters the air passage portion 35, and the splash does not enter the mouth M or the nostril HL. It can prevent "splash infection" that enters directly.

Further, in the case of the present embodiment, unlike a normal sanitary mask in which the mask is placed under the chin, for example, in a normal wearing state, the tip 33b of the convex portion 33 contacts the front face of the face and bites into the skin somewhat. However, it has heights H1 and H2 at which the air passage 35 is not blocked by the unevenness of the face.
In the case of the present embodiment, the convex portion 33 is a convex portion on the lower half side while the height H1 of the convex portion 33-1 provided continuously in the upper half is 2.64 to 4.16 mm. The height H2 of 33-2 and 33-3 is 6.5 mm, and the height H2 of the lower cheek lower convex portion 33-3 which is a region hitting the soft cheek is higher.

More specifically, as shown in FIG. 3, the convex portion 33-1 provided continuously in the upper half has a lower end portion 33-1a slightly extending in the lower half region in front view. As shown in FIG. 4, the height H1 gradually decreases from the nose dorsal K side toward the lower end portion 33-1a.
In addition, regarding the lower half side jaw convex part 33-2 and the cheek lower side convex part 33-3, the jaw side convex part 33-2 facing the chin J and the cheek lower side convex part 33- facing the cheek. 3 is the same height H2 although the cheeks are swollen more than the chin.
Thus, in the relative relationship with the unevenness of the face, the lower cheek lower convex portion 33-3 is formed high, while the lower end portion 33-1a of the convex portion 33-1 is formed with a low height. Thus, a large step is formed in relation to the height between the cheek lower convex portion 33-3 and the lower end portion 33-1a.

Accordingly, as shown in FIG. 5 showing a state in which the lower side of the mask 10 is displaced under the chin, the lower jaw side convex portion 33-2 (FIG. 4) because the wearer's face is small. Even if it is in a state where it has entered the lower jaw, the tip 33b of the lower cheek lower convex portion 33-3 is in contact with the lower jaw bone BN, and the lower cheek lower convex portion 33- The space of the air passage part 35 between 3 and the convex part 33-1 can be made large. Further, the lower end 33-1a is lowered so that a space S3 is also formed between the lower end 33-1a and the cheek CP.
In this way, when the lower side of the mask 10 is shifted below the chin, the air passage between the chin-side convex portion 33-2 of FIG. 3 and the cheek lower-side convex portions 33-3 and 33-3 on both sides thereof. The portion 35 is blocked by the skin, but considering the blocked portion, the air passage portion 35 between the lower cheek lower convex portion 33-3 and the convex portion 33-1 shown in FIG. A space and a space S3 between the lower end 33-1a and the cheek CP are formed, and an air flow path can be secured.

Moreover, as shown in FIG. 3, the air passage part 35 is arrange | positioned at the jaw side (lower side of a figure) at the time of the outer space side 35b wearing compared with the inner space side 35a. In the case of this embodiment, since the front view of the mask body 12 is substantially circular, the air passage portion 35 is arranged on the outer space side by arranging the air passage portion 35 in the lower half region of the Y direction in FIG. It inclines so that 35b may be arrange | positioned below. For this reason, even if splashes, dust, etc. fall from the top due to gravity, or splashes, dust, etc. entered from the left and right sides adhere to the outer space side 35b, the splashes, dust, etc. enter the inner space S1. You can effectively avoid coming.
In addition, as shown in FIG. 6 which is a front view of the mask 10-1 which concerns on the modification of this embodiment, the air passage part 35 is when the outer space side 35b is worn compared with the inner space side 35a. As long as it is relatively arranged on the chin side, it may be arranged in the upper half region in front view. However, as shown in FIG. 3, when the air passage portion 35 is disposed in the lower half region, air can be supplied more smoothly to the nostril HL than when the air passage portion 35 is disposed in the upper half region. Since a large passage space can be ensured, the infant's nasal breathing can be facilitated.

The embodiment of the present invention is configured as described above, and breathing is facilitated by the bulging portion 14, and breathing air is taken in and out from the air passage portion 35 that connects the inner space S1 and the outer space S2. I can breathe easily. For this reason, even if the wearer is an infant or the like, it is possible to effectively prevent the possibility of touching the mouth or the like with the hand after removing the mask, thereby preventing “contact infection”.
The provision of the air passage portion 35 makes it difficult to prevent air infection, but the air passage portion 35 is disposed outside the bulging portion 14 covering the mouth and nostril, and the mask body. 12 is formed on the back side (wearer side). Therefore, it is possible to prevent “spray infection” in which at least splashes due to coughing or the like of an infected person directly enter the mouth or nostril.
As described above, according to the mask 10, it is possible to prevent splash infection and contact infection as compared with the conventional mask in which the mask is removed and not only air infection but also droplet infection and contact infection cannot be prevented. In particular, rhinoviruses, which are known to cause common cold, are said to have more contact infections than air infections and droplet infections. Under such circumstances, the wearing significance of the mask 10 is remarkably high.

By the way, the present invention is not limited to the above embodiment.
For example, although the air passage part 35 of this embodiment is formed in four places on the lower side, the present invention is not limited to this.
Further, the lower side of the mask 10 is displaced under the chin, and the air passage portion 35 between the convex portion 33-2 in FIG. 3 and the convex portions 33-3 and 33-3 on both sides thereof is blocked with skin. If this happens, only the space of the air passage portion 35 between the convex portion 33-3 and the convex portion 33-1 is widened without creating the space S3 shown in FIG. Thus, an air flow path may be secured.
