Abstract

PROBLEM TO BE SOLVED: To solve the problem of devising so that an inner mask is attached to the inside of a cloth member with permeability of a mask worn on a person's face, and, when the face of the wearer faces the front and the wearer inhales, air that is present at the height higher than the nasal cavity entrances of the wearer passes through clearances of fiber-like meshes of the cloth-like member and is sent to the nasal cavity entrances or the mouth of the wearer.SOLUTION: In a state where the radioactive material-preventive inner mask 1 is worn on a person facing the front, a substantially cylindrical part 32 is formed, and the air can go in and out only through the upper face 34 thereof that is located at the height higher than the nasal cavity entrances of the person, or the wearer. When the person wearing the radioactive material-preventive inner mask 1 inhales, air entering through the fiber-like meshes of the cloth-like member 3 that covers an object 10 formed by attaching a balloon-like object to the inner mask body of the radioactive material-preventive inner mask 1, enters from the upper face 34 to the inside of the cylindrical part, and is carried to the nasal cavity entrances or the mouth of the wearer.

Description

The present invention relates to a radioactive substance countermeasure inner mask having a structure in which the amount of radioactive substance scattered from the ground surface and taken into the human body in the air can be made smaller than when a conventional mask is attached.

Except for special masks such as gas masks and dust masks, the masks currently used in the world are rectangular fiber-like shapes that exist in the center across the string-like portions 40 that serve as ear hooks on the left and right. When the portion is attached to the face of a person, the mask as shown in FIG. 1 is formed so as to cover the nose of the person, and the rectangular fibrous portion 39 is the person's face. When mounted on the face, most of them are a three-dimensional mask as shown in FIG. 3 in which the portion in front of the nose of the person is inflated in front as shown in FIG.

However, when inhalation is performed with these masks attached, the part that becomes the air intake of those masks is the fiber in front of the wearer's nasal cavity entrance when the wearer inhales with the nose. If the wearer inhales in the mouth, the part centered on the fibrous part is the part centered on the fibrous part in front of the wearer's mouth.

That is, when the person wearing the mask of FIG. 1 or FIG. 3 faces forward, and the person inhales from, for example, the nasal cavity entrance, the nasal cavity entrance of most persons is When the person's face is facing the front, the person is facing diagonally forward and down, so some of the air on the front side of the wearer is in the nasal entrance of the wearer. The air that is perpendicular to the nasal entrance when viewed from the side, i.e., the air that is diagonally below the front of the nasal entrance, gathers at the air intake from above, below, left, and right, and is A flow occurs that enters the nasal cavity entrance.

In addition, the following patent document 2 can be mentioned as a well-known technique regarding this invention.

Of the plurality of protrusions protruding from the lower surface of the inner mask body 11 having a substantially U-shaped outer periphery, the protrusion protruding from the bent portion of the U-shape of the inner mask body, that is, the root Except for the convex portion having the portion 45 where the bent portion of the U-shape of the inner mask main body enters the portion, all the convex portions protruding from the same inner mask main body 11 have the same shape and the same size. When the inner mask main body 11 having such a convex portion is vertical and the inner mask main body 11 thus made vertical is viewed from the front or the side, the plurality of convex portions present on the lower surface of the inner mask main body. The portions 23 and 24 are present side by side, but when the same portion of the convex portions, for example, the outer tip and the upper tip are connected with a line, Travel around line around the inner mask body caused by connecting these to wherein there to become horizontal.

[0015] If the same parts written in [0015] are connected by a line, the plurality of convex parts 23 and 24, which are in a horizontal line state, are formed in several steps on the lower surface of the inner mask body. The feature is that it exists separately.

The non-breathable stretchable bag-like object 12 has a ring-shaped portion 28 with strong stretchability at the tip, but the bag-like object 12 is attached to the vertical inner mask body. The bag-like object 12 is horizontal or substantially horizontal with the ring-shaped portion 28 of the bag-like object 12 at the upper end, and the bag-like object attached to the lower surface of the inner mask main body. The height of the annular portion 28 is characterized by being variable.

The non-breathable stretchable bag-like object 12 is characterized in that it can be attached to and detached from the inner mask body.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

When the inner mask 1 against radioactive substances is attached to a person's face, the bag-shaped mask 2 has a stretchable and breathable cloth-shaped member body 3 on the inner side of the ear-hook portion 4. The entire radiation substance countermeasure inner mask 1 is present except for the entire portion of the string-like member 29 serving as the part. (See FIGS. 33 and 40)

The mask 2 in the shape of a bag is viewed from the side when it is mounted on a person's face with the radioactive substance countermeasure inner mask 1 inside as described in [0020] above. In the case, the front tip of the bag-shaped mask 2 is located in a vertical straight line, or the middle part of the vertical straight line. There is what becomes the forefront part of the place that protrudes in front of the place of the neighborhood. (See FIGS. 10 and 12)

When the bag-shaped mask 2 is mounted on a person's face as described above when viewed from the back of the bag-shaped mask without the wearer's face. From the corners of the upper, lower, left and right four side portions 7, 8, 9 which are in the state of the rear end of the cloth-like member main body 3 existing in the state of becoming the majority of the bag-shaped mask 2. Two elastic string-like members 5 are connected to the upper and lower ends of the left and right vertical sides 9 of the four sides, and serve as two pairs of left and right ear hook portions of the bag-shaped mask. Although present, the bag-like mask 2 is composed of the cloth-like member main body 3 and the string-like member 5 which is an ear hook portion. (See Figure 31)

The four side portions 7, 8, 9 and the vicinity of the cloth-shaped member main body 3 are located on the inner side of the cloth-shaped member main body 3 when the bag-shaped mask 2 is attached to the face of a person. Part of the other cloth-like member main body 3 excluding the part where the magic tape described later is present because it is folded in the direction in which it is folded and further is sewn with a thread or the like from above. It is thicker than. (See FIGS. 6, 35, and 36)

When the person wears the bag-shaped mask 2, the four-side portions 7, 8, 9 of the cloth-shaped member body 3 of the bag-shaped mask 2 are the four-side portions 7, 8. , 9 is the upper skin of the nose below the wearer's eyes and the left and right skin of the upper skin of the nose, and the lower 8 is the surface facing the lower side of the wearer's chin and under the chin. The skin on the lower side of the side cheeks on the left and right sides of the facing surface, and the left and right vertical sides 9 are in close contact with the skin of the wearer's side cheeks or are in close contact with the inside of the cloth-like member body 3. The cloth-shaped member main body 3 is completely covered with the balloon-shaped object 12 attached to the inner mask main body 11 of the existing radioactive substance countermeasure inner mask 1. (See FIGS. 10, 11, 12, and 41)

The cloth-shaped member main body 3 has an extremely thin thread-like member on the inner surface of the cloth-shaped member main body 3 when the bag-shaped mask 2 is attached to a person's face. There are several tens or dozens of velcro tapes that are sewn in the vertical direction. The velcro mask 2 has the bag-shaped mask 2, and the most part of the radioactive substance countermeasure inner mask 1. When it is attached to the face of a person with the side facing the edge, it is in close contact with the magic tape affixed to the surface of the wall-shaped portion 13 of the inner mask body of the inner mask against radioactive material. ing. (See FIGS. 12, 13, 15, and 31)

A radioactive material countermeasure in which an inner mask body 11 in which the balloon-like object 12 is attached is present inside a cloth-like member body 3 of the bag-shaped mask 2 when worn on the face of a person. The inner mask 1 is constituted by the inner mask body 11, the balloon-like object 12, and a string-like member 29 which is a pair of left and right ear hook portions 14. (See FIGS. 8, 16, 19, 25, 29, and 30)

When the radioactive substance countermeasure inner mask 1 is mounted on the face of a person facing the front, behind the left and right upper portions of the wall-shaped portion 13 of the non-breathable inner mask main body 11 included in the radioactive substance countermeasure inner mask 1 On the side, there is a vertically elongated cheek rest portion 15 that is softer than the wall-shaped portion, but the cheek rest that is also the boundary between the wall-shaped portion 13 and the cheek rest portion 15. The vertical side of the rear end of the wall-like part that continues downward from the front-end vertical side 16 of the part, that is, the vertical side 17 of the rear end of the wall-like part of the inner mask body, or the back of the cheek rest part The state in which the vertical side 18 of the end is the cheek pad portion 15 is upward, that is, the inner mask body 11 included in the radioactive substance countermeasure inner mask or the radioactive substance countermeasure inner mask is placed on the face of the person facing the front. Radioactive State a state in which the quality measure inner mask are perpendicular in the same position as mounted radioactive materials countermeasure inner mask becomes vertical, like the inner mask body 11 becomes vertical

When the inner mask main body 11 of the radioactive substance countermeasure inner mask 1 is viewed from the side vertically, the front tip portion of the inner mask main body that looks like a vertically long rectangle is a vertical vertical line as a whole. What is visible and the height corresponding to the center of the vertical line is the front tip of the curve protruding forward, and the front tip of the curve protruding forward is the front tip of the inner mask body 11. There are things. (See FIGS. 8 and 32)

When the inner mask body 11 is also viewed from the side with the inner mask body 11 vertical, the upper surface 19 and the lower surface 20 of the wall-shaped portion 13 of the inner mask body 11 both have the same height on the left and right sides. The upper surface 19 and the lower surface 20 of the shaped portion are horizontal. (See FIGS. 32 and 38)

Then, on the rear side of the upper portion of the wall-shaped portion 13 of the inner mask body 11, the upper side 21 having a soft hardness as compared with the wall-shaped portion 13 is disposed on the upper surface of the wall-shaped portion. There is a portion 15 of the cheek rest that is a vertically long rectangle on the extended line that continues from the above. (See FIGS. 8, 14, 29, and 30)

And, the lateral side 22 below the cheek rest portion 15 of the vertical inner mask body 11 is horizontal, and is below the extension line in front of the horizontal side 22 below the level, that is, the inner mask body. A plurality of protrusions 23 and 24 are present on the lower surface, and these protrusions are the inner mask body of the plurality of protrusions protruding from the lower surface of the inner mask body 11 having a substantially U-shaped outer periphery. Except for the convex portion protruding from the bent portion of the U-shape, that is, the convex portion having the portion 45 where the bent portion of the U-shape of the inner mask body enters the base portion. All the convex portions protruding from the inner mask main body have the same shape and the same size, and the inner mask main body 11 having such convex portions is set to be vertical, and the vertical inner mask main body 11 is faced to the front. When viewed from the side, the portion 42 that appears as the upper side of the convex portion and the portion 43 that appears as the lower side are in a horizontal state and protrude outward, and the convex portion 23 , 24 are divided into several levels of height, and the same portion of the convex portion at each height, for example, the outer tip and the upper tip are connected by a horizontal line. In this case, the line surrounding the inner mask body generated by connecting them is horizontal. (See FIGS. 29, 30, 32, 38, 39, and 42)

The protrusions 23 and 24 projecting outward from the surface of the inner mask main body 11 are of two types, a substantially cylindrical shape and a substantially plate shape, and the main body 11 of the inner mask has only the substantially cylindrical protrusion and the Some of them have only a substantially plate-like convex portion, and each of the convex portions 23 and 24, particularly the substantially plate-like convex portion 24, is not a single sheet that surrounds the periphery of the surface of the inner mask body 11, but a plurality of them. The reason why they exist separately is that the left and right rear ends of the wall-shaped portion 13 of the inner mask body 11 can be easily spread to the left and right even with a weak force. (See FIGS. 8, 25, 29, 32, and 42)

Then, on the upper part of the front part of the wall-shaped partial surface of the inner mask main body 11, a velcro tape in a state where the vertical line 41 at the center of the front part of the inner mask main body 11 is centered is attached. (See FIGS. 25 and 29)

When the inner mask body 11 is viewed from the side with the inner mask body 11 in a vertical position from the left and right side surfaces of the wall-shaped portion 13 of the inner mask body 11 to the same position on both the left and right sides, that is, the positions where the respective sides are symmetrical. , There are two parts 25 for attaching a string-like member that exists in a vertical relationship with the upper part before the lower part, and there are a total of four parts on one side and four on the left and right sides. The part 25 to which the substantially rectangular string-like member that protrudes outward from the side surface of the inner mask main body is attached to all four bodies is closer to the side surface of the inner mask main body than the other left and right surface parts. It becomes the part 37 which becomes the concave recessed inside (refer FIG.5, FIG.18, FIG.37).

The plurality of substantially cylindrical or plate-like convex portions 23 and 24 protruding outward from the surface of the wall-shaped portion 13 of the inner mask main body 11 are stretchable and non-breathable bag-like. When the object, that is, the balloon-like object 12 is attached to the lower part of the inner mask body 11, the balloon-like object 12 attached to the inner mask body is moved from the lower position of the inner mask body to the lower surface. This is for preventing the balloon-like object 12 from being displaced in the direction or falling off from the inner mask body 11. (See FIG. 8, FIG. 25, FIG. 29, FIG. 30, FIG. 32, FIG. 33)

The balloon-shaped object 12 has a ring-shaped portion 28 that is thicker than the other portions, and the cross-sectional cut surface of the ring-shaped portion 28 is a substantially circular outer periphery. There is a material that is filled with a vinyl-like material or a rubber-like material of the same material as the other parts, or a material that is spirally wound toward the outside or inside of the ring. (See FIGS. 21, 22, 23, and 24)

The method of attaching the balloon-shaped object 12 to the inner mask body 11 is very simple, for example, with the balloon-shaped object 12 in a state where a ring-shaped portion is on the lower side, and Put all the fingers other than the thumb with the back of both hands facing left and right from the bottom of the ring, and all the fingertips other than the thumb face up. If the four fingers are bent inwardly, then the four fingers are opened outwards, and the four fingers are opened outwards and pulled to the left and right, the ring of the ring-shaped portion 28 becomes larger. The above-mentioned enlarged ring portion 28 was placed upside down on a flat surface of a desk or the like, with the lower surface 26, ie, the lower surface when it became a substantially cylindrical portion, facing up. Cover the inner mask body 11 from the lower surface. Mounted so as to cover the lower portion of the inner mask body 11, including the lower surface thereof. (See FIGS. 27 and 38)

The method of changing the height of the ring-shaped portion 28 of the balloon-like object when the balloon-like object 12 is attached to the inner mask body 11 is extremely simple. It is necessary to first remove the balloon-like object attached to the inner mask body.

The method of removing the balloon-like object 12 from the radioactive substance countermeasure inner mask is very simple, and the ring-shaped portion 28 of the balloon-like object is made to be larger than the outer periphery of the inner mask body by about two times. However, as a method of creating the first stage for achieving this state, hold the part of the inner mask body 11 of the radioactive substance countermeasure inner mask 1 other than the part not covered by the balloon-like object with one hand. One way is to put the other hand into the ring-shaped part 28 of the balloon-shaped object 12 and pull the hand to expand the ring in the ring-shaped part 28. is there. (See Figure 30)

When the balloon-like object is attached to the inner mask body in the manner of [0037], the ring-shaped portion 28 of the balloon-like object is divided into several stages, and the inner mask body 11 is now in the upper state. Between the rows of convex portions on the lower surface, or when the person wears the radioactive substance countermeasure inner mask 1, the uppermost convex portions 23 and 24 are arranged in rows, and the current lower row The height of the ring-shaped portion 28 of the balloon-like object 12 when it is attached to the inner mask main body 11 varies depending on whether it is placed below the row of the convex portions 23, 24. Further, even if the balloon-like object 12 attached to the inner mask body 11 is not removed from the inner mask body 11, the ring-shaped portion 28 of the balloon-like object 12 attached to the inner mask body 11 is extended. The height of the ring-shaped portion 28 can be changed. (See FIGS. 27 and 30 and FIG. 38)

And when the inner mask main body 11 made vertical is viewed from above, the wall-shaped portion 13 of the inner mask main body 11 is roughly divided into a substantially U-shape and a substantially U-shape. The substantially U-shaped and U-shaped wall-shaped portion 13 has a front tip portion that is vertical and a front tip portion that is a tip portion of a curve that protrudes forward. There is a thing, and the inner mask main body 11 that is all vertical is in a shape that is symmetrical when the center of those 11 is cut vertically. (See FIGS. 8, 15, 14, 32, and 33)

As described above, the cheek pad portion 15 of the inner mask body 11 is very soft compared to the wall-shaped portion 13, and the cheek pad portion 15 is a vertical inner mask. When the main body is viewed from above, it is opened to the outside at an angle of about 1 degree to 20 degrees from the invisible rear extension line of the rear part of the wall-like part in front of the wall part symmetrically when viewed from the left and right. For example, the inner mask main body 11 is made to lightly touch the left and right cheek pad portions 15 of the inner mask main body 11 on the surface of a flat wall protruding vertically from the ground, and the inner mask main body When a finger is applied to the front surface and a force is applied toward the surface of the flat wall, the left and right cheek support portions 15 are parallel to the surface of the flat wall, and the cheek support at that time Located in front of part 15 The rear part of the wall-shaped part is perpendicular to the surface of the flat wall, and when an additional force is applied to the finger applying a force toward the surface of the flat wall, the inner mask body 11 is in a state of floating in the air only by the pressure pressed by the finger and the pressure coming from the surface of the flat wall, but the wall-shaped portion 13 of the inner mask main body has the inner mask main body in the air as described above. It has a hardness that does not change its shape immediately after it floats. (See FIGS. 29, 32, and 34)

In addition, when viewed from the side in a vertical state instead of the inner mask body in which the front tip portion is swollen forward, the lower portion of the inner mask body having the front tip portion in a vertical vertical line state is When the object covered with the balloon-shaped object 12 is vertically viewed from below, the balloon-shaped object 12, the cheek pad portion 15 of the inner mask body, and the portion 25 for attaching the string-like member are A horizontal line in which the ring-shaped portion 28 of the balloon-like object 12 attached to the lower portion of the inner mask body is divided into several levels at the lower portion of the inner mask body and is connected to the same portion. If it is between the lines connecting the convex parts that exist in a horizontal state, see the inner mask body shown above with the balloon-like object attached from below. In addition to the state and becomes visible portions when, sometimes in a state in which a part is visible in the convex portion of the upper from the portion 28 of the annular. (See Figure 7)

When the radioactive substance countermeasure inner mask 1 attached to the face of a person and viewed in a vertical state is viewed from the side, the upper surface 19 of the wall-shaped portion is above the entrance of the wearer's nasal cavity and the lower surface 20 is In other words, the person should wear the radioactive substance countermeasure inner mask 1 that is at or near the lower tip of the wearer's chin and changes to the above state. (See Figure 33)

The balloon-shaped object 12 of the radioactive substance countermeasure inner mask 1 in the above [0044] state has a ring-shaped portion 28 facing the rear side, that is, the wearer side, below the mouth of the wearer. It is in close contact with the front-facing surface of the chin, and the lower part of the ring-shaped portion is the front-facing surface of the wearer's chin, or the front-facing surface of the chin and the bottom of the chin. Close contact with the surface. (See FIGS. 26 and 33)

When the radioactive substance countermeasure inner mask 1 is worn on a person's face, the person, that is, the wearer's mouth, a portion facing the skin around the mouth, the inner mask body 11 and the balloon-like shape. Is formed in a state of forming a substantially cylindrical portion formed by the object 12, but the internal state when the radioactive substance countermeasure inner mask 1 mounted on the face of a person is viewed from the side is There is always a gap between the front tip of the wearer's nose and the inner surface 31 of the wall-like portion located in front of the front tip of the nose. (Refer to FIG. 28 and FIG. 33)

Then, when the radioactive substance countermeasure inner mask 1 mounted on a person's face is viewed from the front, the upper surface 19 of the wall-shaped portion 13 of the inner mask body 11 is always above the nasal cavity entrance of the wearer. When the wall-shaped portion is horizontal, the cheek rest portion 15 having the upper end in the horizontal state at the same height as the upper surface of the wall-shaped portion is a measure against radioactive material. The inner mask is more open than when it is not worn on the face of the person and is in close contact with the cheek of the wearer, and the cheek rest 15 is in close contact with the cheek of the wearer. 15, the wall-shaped portion 13 including the boundary portion 16 between the wall-shaped portion and the cheek rest portion is the skin outside the left and right ends of the wearer's mouth. And the vertical side 18 at the rear end of the cheek rest 15 , In close contact with the cheek of the wearer in a state in which the lateral cheeks of the wearer does not protrude outside. (See FIGS. 26, 28, 29, and 33)

And, the lower surface 30 of the radioactive substance countermeasure inner mask in a state covered with the balloon-like object 12 when the radioactive substance countermeasure inner mask 1 mounted on the face of the person is vertically viewed from the front, It exists horizontally at or near the lower tip of the wearer's chin or at a height below the lower tip of the chin. (See FIGS. 15, 33, and 40)

The state of the portion on the back side of the balloon-like object 12 included in the radioactive substance countermeasure inner mask in the above [0048] state, that is, the wearer side, is that the annular portion 28 is horizontal, or It is in close contact with the skin of the part facing the front of the lower jaw from the wearer's mouth, and the lower part of the ring-shaped part is the surface facing the front of the jaw, or the jaw The skin is in close contact with both the front-facing side and the underside of the chin. (See FIGS. 26, 33, and 40)

Then, when the radioactive substance countermeasure inner mask mounted on a person's face is viewed from above, the inner surface 31 of the wall-shaped portion of the inner mask body 11 is the skin on the surface of the wearer's nose. It seems that it is not touched at all. (See FIGS. 28, 33, and 40)

The radioactive substance countermeasure inner mask 1 is mounted on a person's face in the above-described state, so that the wall-shaped portion 13 of the inner mask body 11 included in the radioactive substance countermeasure inner mask 1 and the wearer's mouth are provided. And the skin around the mouth can form a substantially cylindrical portion 32, and the substantially cylindrical portion of the wall-shaped portion 13 of the inner mask body forming the substantially cylindrical portion 32. The entire portion on the wearer side of the non-breathable balloon-like object 12 covering the lower portion of the wall-like portion including the lower portion 26 is in close contact with the skin under the wearer's mouth. The outside air cannot enter from the lower part of the substantially cylindrical part including the lower surface 33 of the substantially cylindrical part, and when the wearer inhales, The upper surface of the substantially cylindrical part is 4, and as described above, the upper surface 34 of the substantially cylindrical portion is that when the wearer is facing the front and the radioactive substance countermeasure inner mask 1 worn by the wearer is vertical, It is in a state above the nasal cavity entrance of the wearer. (See FIGS. 15, 25, 26, 33, and 40)

As described up to now, the vertically disposed radioactive substance countermeasure inner mask 1 mounted on the face of a person serves as an air intake port in a horizontal state. The upper surface 34 of the substantially cylindrical portion is above the nasal cavity entrance of the wearer. For example, when the wearer inhales from the nasal cavity entrance, It is unlikely that the air in front of the wearer at the height near the tip will rise once and then bend down near the air intake to enter the wearer's nasal cavity entrance. 1 and FIG. 3 has a structure in which the upper, lower, left, and right air existing in front of the air intake port enters from the air intake port when the person who wears inhales the air. Radioactive substances present in the body Has a can structure it to reduce the amount to take. (See FIGS. 1, 3, 33, and 40)

In addition to the above [0052], when radioactive materials are present on the ground surface, it is natural that the concentration of radioactive materials floating in the air soars due to wind etc. Since the closer to the ground, the darker it becomes, so when comparing the conventional mask of FIG. 1 and FIG. 3 with the radioactive substance countermeasure inner mask, it is natural that the person who inhales with the radioactive substance countermeasure inner mask 1 inspires. It is clear that it is good.

And the method of mounting the radioactive substance countermeasure inner mask 1 on the face of a person is very simple. First, the method is to use the cheek pad 15 of the inner mass body 11 of the radioactive substance countermeasure inner mask. The upper side which is horizontal if the inner mask body is vertical, i.e., above the height of the nasal cavity entrance of the wearer's face with the upper side 21 facing the front, and below the eyes, and The left and right cheek rests 15 are widened with both hands, the cheek rest 15 having the wide angle is brought into close contact with the wearer's cheek, and the front edge 16 of the cheek rest 16 That is, the vertical side of the boundary between the wall-like portion and the cheek rest is touched by both ends of the mouth, the skin outside the invisible vertical line 46, and the vertical side 18 behind the cheek rest is Protruding outside the wearer's side cheek In close contact with the skin, and when the cheek rest 15 is in the state described above, the wearer's nose front and front of the nose front tip It is confirmed that there is a gap between the inner surfaces 31 of the wall-like portion 13 in the wall. (See FIGS. 14, 15, 26, 28, 33, and 40)

Further, the distance between the straight lines connecting the vertical sides 17 at the left and right rear ends of the wall-shaped portion 13 of the inner mask body 11 in the shortest is shorter than the width of the wearer's mouth and the wall-shaped portion 13. When the cheek pad portion 15 of the inner mask 1 having radioactive substance is pressed against the face of the wearer, the front vertical side of the cheek pad portion is invisible to the invisible vertical line 46 that touches both ends of the wearer's mouth. When 16 touches or enters the inside of the invisible vertical line, the vertical sides 17 at the left and right rear ends of the wall-shaped portion 13 of the inner mask body of the radioactive substance countermeasure inner mask 1 are expanded to the left and right. [0054] is sufficient. (See FIGS. 26, 28, 14, and 45)

And when the radioactive substance countermeasure inner mask 1 is pressed against the wearer's face, the vertical side 18 at the rear end of the cheek rest part comes out of the wearer's lateral cheek, and the radioactive substance countermeasure inner mask 1 may be shifted to the back side of the wearer's face, the radioactive substance countermeasure inner mask 1 in the state of [0054] above is replaced with a radioactive substance countermeasure inner mask 1 having a size of [0055]. It ’s fine.

When the state of [0054] is reached, the ring-shaped portion 28 on the wearer side of the balloon-like object 12 mounted on the lower part of the inner mask body is below the mouth of the wearer. It is in close contact with the surface facing the chin, and the portion under the ring-shaped portion 28 on the wearer side faces the front surface of the wearer's chin or the front of the chin. It is in close contact with both the facing surface and the surface facing the chin. (See FIGS. 26, 33, and 40)

When a person tries to wear the radioactive substance countermeasure inner mask 1, the cheek rest part 15 of the radioactive substance countermeasure inner mask 1 is in the state of [0054], and the cheek rest part is in the state of [0054]. When the balloon-shaped object 12 included in the radioactive substance countermeasure inner mask 1 does not enter the state [0057], that is, the ring-shaped portion 28 on the wearer side of the balloon-shaped object 12 is mounted. When the person touches the person's mouth, the height of the balloon-like object 12 may be changed as shown in [0040], but the position of the balloon-like object may be changed. If the state does not become [0057], the person may wear it instead of the radioactive substance countermeasure inner mask 1 that becomes the state [0057] when [0054] is reached.

The portion on the back side of the inner mask 1 against radioactive material is pressed against the face of a person, and when the state becomes [0054] and [0057], a pair of left and right ear hooks extending from the side surface of the inner mask body 11 If the 14 elastic string-like members 29 are placed on the left and right ears, the work of mounting the radioactive substance countermeasure inner mask on the person's face is completed, and the upper part of the radioactive substance countermeasure inner mask 1 worn on the person is placed. The mask 2 in the shape of a bag is covered, and several or dozens of magic tapes and inner masks in the cloth-shaped member main body 3 of the bag-shaped mask 2 are provided. A pair of left and right ear hooks extending from the cloth-like member 3 is adhered to the surface of the cloth-like member main body by pressing the surface of the cloth-like member body inward with a finger or the like. If the four string-like members 5 are put on both ears of a person, and if the wearer inhales in that state, the cloth-like member main body 3 of the cloth-like member main body 3 of the bag-like mask 2 has A phenomenon occurs in which the air entering from the eyes enters through the air intake 34 of the inner mask 1 against radioactive material. (See FIG. 10, FIG. 11, FIG. 12, FIG. 13, FIG. 15, FIG. 25, FIG. 26, FIG. 33, FIG. 40)

Further, the string-like member 29 coming out from the portion 25 to which the string-like member of the inner mask main body of the radioactive substance countermeasure inner mask is attached is replaced, that is, the string coming out from the portion 25 to which the string-like member is attached. The member 29 can be removed, or a new string member can be attached to the portion 25 to which the string member is attached, but these methods are very simple and will now be described. To do.

The string-like members 29 that form the left and right ear hook portions are stretchable, and the portions 35 at both ends of the string-like members 29 have small ring shapes. (See FIGS. 16 and 19)

The end portions 35 of the string-like member 29 that are part of the pair of left and right ear hook portions of the radioactive substance countermeasure inner mask 1 are located on the side surfaces of the inner mask body 11. When the inner mask body 11 is viewed from the side when it is vertical, the upper part is close to the side surface of the side surface of the inner mask body, with the upper part located in front of the lower part. The portion is attached in a form that is substantially rectangular with a width compared to the other portions, and that tightens the portion 25 to which the string-like member protruding from the side surface of the inner mask main body is attached. (See FIGS. 15, 18, and 37)

The portion 35 at both ends of the string-like member 29 and the vicinity thereof are places where the width of the portion 25 to which the string-like member is attached is narrower than other portions near the side surface of the inner mask body, that is, from the left and right ends to the inside. It is attached in the form of tightening the recessed portion 37 which is recessed. (See FIGS. 18 and 37)

The method of removing the string-like member 29 from the portion 25 to which the string-like member of the inner mask body 11 is attached is such that the recess around the outside of the portion 37 that becomes the recess of the portion to which the string-like member is attached. The ring-shaped portion 35 at the end of the string-like member positioned in a state where the formed portion 37 is tightened or the vicinity thereof is pulled toward the front with a pinch pliers or the like. (See FIGS. 16 and 17)

[0064] By doing so, the ring of the ring-shaped part 36 having the small ring-shaped part rooted at the ring-shaped part at the end of the string-shaped member becomes large, that is, the part 25 for attaching the string-shaped member. Is a state in which there is a sufficient gap in the ring of the ring-shaped part 36 that is based on a small ring-shaped part that has been tightened itself 25 and that is larger than before. Therefore, the string-like member 29 can be easily removed from the portion 25 to which the string-like member is attached, that is, the inner mask main body. (See Figure 17)

Then, the method of attaching the string-like member 29 to the inner mask body 11 is as follows. First, a small ring-shaped portion 35 at both ends of the string-like member 11 is pinched with fingers to form a ring. The tip of the ring made by pinching, that is, the portion of the ring that seems to be farthest from the place pinched by the finger is made an acute angle, and the sharp tip of the sharpened portion 38 is made of the string-like shape. A ring-shaped portion having the small ring-shaped portion as a base is inserted into the ring-shaped portion 35 of the ring-shaped portion 35 at the end of the member, that is, inserted, and the inserted acute-angled tip is further inward. 36, so that the portion 25 for attaching the string-like member comes in the ring of the ring-shaped portion 36 having the small ring-shaped portion as the root, and the ring is gradually reduced, and Finally that day The concave portion 37 of the portion for attaching the member is tightened with the string-like member, and the operation is performed four times, and the inner mask main body 11 and the string-like member are brought into a state as shown in FIGS. This completes the work of attaching the string-like member to the inner mask body. (Refer to FIG. 16, FIG. 18, FIG. 19, FIG. 5, FIG. 43, FIG. 44)
