Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a humidifying mask that allows the user to breathe in a state in which moisture is added to the air.

[Prior art] In most environments controlled by air conditioning equipment, such as the cabin of an airplane, the air is excessively dry, and people with weak respiratory organs are likely to get sick, and even healthy people can be exposed to such dry environments. Prolonged exposure to it can irritate the throat and even cause mild pneumonia. For this reason, the applicant proposed a humidifying mask as a mask for protecting the respiratory organs from a dry environment in Japanese Patent Application No. 64,180/1980.

This humidifying mask has a mask body shaped like a bag with a closed lower part.The mask body is provided with many small breathing holes in the part corresponding to the external nostrils and is impregnated with moisture. A water-retentive breathable sheet such as 100% water-retentive material is inserted into the mask body at the part corresponding to the breathing hole.

When you put this humidifying mask on your face from your nose to your mouth, the air passes through the water-retaining ventilation sheet and is inhaled into your respiratory system. It absorbs moisture and becomes appropriately moist, which protects the respiratory organs from dry air.

EProblem to be Solved by the Present Invention 1 In this humidifying mask, the water-retaining ventilation sheet impregnated with water is inserted into the opening at the upper end of the mask body and set inside the mask body. I have to. However, the mask body is thin in order to be worn on the face from the nose to the mouth, and it is extremely difficult to insert and set the ventilation sheet into the thin mask body through the opening at the top ( This was a problem in terms of ease of use.

The present invention has been made in view of the above points, and provides a humidifying mask that is easy to use and allows a water-retentive ventilation sheet impregnated with water to be easily set inside the mask body. The purpose is to

Means for Solving Problem E] The humidifying mask according to the present invention has an inner mask half 1 and an outer mask half each having a concave curved shape on the inner surface that follows the facial area extending from the nose to the mouth. At the same time, breathing holes 3.3 are formed in the parts corresponding to the external nostrils and mouth of the inner mask half body 1 and the outer mask half body 2, respectively, and the outer mask half body 1 is formed on the outside of the inner mask half body 1. The mask body 4 is formed by overlapping the bodies 2 and bringing the lower edges of each mask half 1 and 2 into close contact with each other, and joining the inner mask half 1 and the outer mask half 2 in a manner that can be freely worn under the skin.
It is characterized in that a water-retaining ventilation sheet 5 that forms and impregnates moisture is sandwiched between the inner mask half 1 and the outer mask half 2 at the breathing holes 3.3. be.

[Function J] By making it possible to divide the mask body 4 into two, the inner mask half 1 and the outer mask half 2, the ventilation sheet 5 can be set with the mask body 4 separated and wide open. This makes it possible to easily set the ventilation sheet 5 on the mask body 4, thereby increasing ease of use.

[Example] The present invention will be explained in detail below with reference to Examples.

The inner mask half 1 and the outer mask half 2 are formed by molding a flexible, soft or semi-hard plastic that has shape retention properties, such as polyethylene or polypropylene. The body 2 is formed in a concave shape so that the inner surface thereof is a concave curved surface that follows the facial area from the nose to the mouth. Inner mask half 1
Both of the outer mask half 2 have a large number of breathing holes 3.3 at positions corresponding to the external nostrils and mouth, as shown in FIGS. 2(a) and 3(b) and 3(a) and 3(b). Further, in the portion where the breathing hole 3 is provided, a large number of needle-like small protrusions 6, 6, . . . with sharp tips are protruded from the edge of each breathing hole 3. These needle-like small protrusions 6 are provided on the outer surface of the inner mask half 1 and the inner surface of the outer mask half 2, but it is not necessarily necessary to provide them on both the inner mask half 1 and the outer mask half 2. , may be provided on at least one of the outer surface side of the inner mask half body 1 and the inner surface side of the outer mask half body 2.

In the inner mask half 1, a recess s8 is formed in a concave manner on the outer surface side of the part where the breathing hole 3 is formed, and a locking flange is provided along the lower edge of the inner mask half 1. 9 is folded back to the outer surface side and integrally extends upward. Furthermore, string passing holes 10 are formed at both ends of the inner mask half 1, and a locking tube 11 is provided at the periphery of the string passing hole 10 so as to protrude toward the outer surface of the inner mask half 1. It is integrated.

Further, locking protrusions 12 are provided at a plurality of locations on the upper edge of the inner mask half 1 so as to integrally protrude outward.

On the other hand, on both side ends of the outer mask half 2, through holes 13 are provided at positions corresponding to the string passing holes 10 of the inner mask half 1, and furthermore, the upper edge of the outer mask half 2 A locking hole 14 is provided at a position corresponding to the locking protrusion 12 of the inner mask half 1.

Thus, the mask body 4 is constituted by the inner mask half 1 and the outer mask half 2. The ear hooks are passed through strings 15 to prevent both mask halves 1 and 2 from coming apart. The outer mask half 2 is then superimposed on the outer surface of the inner mask half 1 and polymerized to form a mask body 4 as shown in FIG. 1. A ventilation sheet 5 is inserted into the mask body 4. Set and use. As the ventilation sheet 5, a material such as a filter such as gauze, which has excellent ventilation and water retention properties, is used. When setting this ventilation sheet 5 inside the mask body 4, it is necessary to insert the inner mask half 1 and the outer mask half. With the half body 2 separated, the ventilation sheet 5 is sandwiched between the inner mask half body 1 and the outer mask half body 2, and then the inner mask half body 1 and the outer mask half body 2 are joined together. Just do it. Therefore, the ventilation sheet 5 can be easily set on the mask body 4 without any difficulty in operation as in the case of inserting and setting the ventilation sheet 5 into a narrow gap. When setting the ventilation sheet 5 in the mask body 4, it is desirable for operability to do so without impregnating the ventilation sheet 5 with moisture. It is preferable to insert a dropper through the breathing hole 3 to supply moisture to the ventilation sheet 5. The amount of moisture supplied to the ventilation sheet 5 is preferably adjusted depending on the dryness of the air.

In addition, when combining the inner mask half 1 and the outer mask half 2 to form the mask body 4, the inner mask half 1
The outer mask half 2+y is attached to the inside of the locking flange piece 9 provided on the lower edge of the
) By inserting the lower edge, the lower edge of the outer mask half 2 is brought into close contact with the lower edge of the inner sleeve half 1, so that the lower edge of the mask body 4 is sealed.

Furthermore, the locking tube 11 provided on the inner mask half 1 is inserted into the through hole 13 of the outer mask half 3, and the locking protrusion 12 provided on the inner mask half 1 is inserted into the locking hole 14 of the outer mask half 2. 4(a), the protrusion 16 provided at the tip of the locking tube 11 is locked to the periphery of the through hole 13, and the locking tube 11 is locked as shown in FIG. 4(b). The protrusion 17 provided at the tip of the protrusion 12 is engaged with the periphery of the engagement hole 14, and the mask body 4 is
The upper edge is also covered. Although the inner mask half 1 and the outer mask half 2 can be combined in this way, the inner mask half 1 and the outer mask half 2 can also be separated by the reverse operation. It is also possible to easily take out the ventilation sheet 5 in this state.

The ventilation sheet 5 set inside the mask body 4 as described above is sandwiched between the inner mask half 1 and the outer mask half 2, and is inserted into the breathing holes 3, 3 of each mask half 1, 2. At this time, the ventilation sheet 5 is fitted into the recess 8 of the inner mask half 1, as shown in FIG. In addition, it can hold the inner mask half 1
and needle-like small protrusions 6, 6, formed protruding from the outer mask half 2.
By digging into the surface of the ventilation sheet 5,
The ventilation sheet 5 is attached to the ventilation holes 3, 3 with needle-like protrusions 6, 6.
...so that it can be held securely.

The humidifying mask formed as described above is put into use by being worn on the face by covering the mask body 4 from the nose to the mouth and hanging the ear hooks 15 around the ears, as shown in FIG. When breathing, air passes through the ventilation sheet 5 through the breathing holes 3 and is inhaled into the respiratory organs.

At this time, when the air passes through the ventilation sheet 5, it absorbs the moisture contained in the ventilation sheet 5 and becomes excessively humid, thereby protecting the respiratory organs from dry air.

In the above embodiment, the locking flange piece 9 is attached to the lower edge of the inner mask half 1.
By inserting the lower edge of the outer mask half 2 into the inside of this locking flange piece 9, the lower edges of both mask halves 1 and 2 are brought into close contact with each other, so that the lower edge of the mask body 4 is sealed. However, by providing a protrusion on one of the lower edges of the inner mask half 1 and the lower edge of the outer mask half 2 and a concave on the other, and fitting the protrusions and recesses, the lower edges of the inner mask half 1 and the lower mask half 2 are The edges may be brought close together. It is sufficient to impregnate the ventilation sheet 5 with moisture to the extent that the ventilation sheet 5 contains moisture, and there is no need to strictly seal the lower edge of the mask body 4.

,! In addition, it is preferable that the inner mask half 1 and the outer mask half 2 be colored milky white or pink so that the nose and mouth cannot be seen through when the mask body 4 is attached to the face. In the above embodiment, a large number of breathing holes 3 are provided on the entire surface of the inner mask half 1 and the outer mask half 2 in the area corresponding to the external nostrils and the mouth. It is also possible to omit the breathing hole 3 and allow the breath from the nose and mouth to exit from both sides of the mask body 4 instead of coming out from the front, so that the person facing the person does not get breath. Of course, the humidifying mask according to the invention can also be used without impregnating the ventilation sheet 5 with moisture, and in this case, it can be used as a normal mask to prevent bacteria, dust, etc. from entering the respiratory organs. It is something.

[Effects of the Invention] As described above, in the present invention, the inner mask half and the outer mask half are formed in a concave shape having a curved surface on the inner surface that follows the facial area extending from the nose to the mouth. At the same time, ventilation holes are made in the parts of the inner mask half and the outer mask half that correspond to the external nostrils and mouth, and the outer mask half is stacked on the outside of the inner mask half, and the lower edge of each mask half is The mask body is formed by freely joining the inner mask half and outer mask half while keeping the inner mask half and outer mask half in close contact with each other, and a water-retaining breathable sheet that impregnates moisture is attached to the inner mask half at the breathing holes. Since it is sandwiched between the outer mask half and the outer mask, when breathing, the air passes through the ventilation sheet and is inhaled into the respiratory tract while absorbing moisture, separating dry air from dry air. The purpose is to protect the respiratory organs, and when setting the ventilation sheet inside the mask body, separate the inner and outer mask halves and insert the ventilation sheet into the inner mask half. This can be done by sandwiching it between the outer mask half and joining the inner mask half and outer mask half in this state. Therefore, it is similar to when setting by inserting a ventilation sheet into a narrow gap. The ventilation sheet can be easily set on the mask body without any difficulty, and it is easy to use.
