DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the structure and effects of a folder type dustproof mask according to the present invention will be described with reference to the accompanying drawings.

Fig. 1 is an exploded top plan view of two folding faces of a folding type dustproof mask according to the present invention before being joined.

As shown in FIG. 1, the folding type dustproof mask 10 according to the present invention forms a three-dimensional dust mask by combining the folder type of the first folder surface 11 and the second folder surface 12.

The folder surface may be composed of a laminated sheet or a single-layer sheet, and a filter or the like not shown may be formed outside the mask.

The first folder surface 11 is a panel having an upper joining portion 111 and first and second side joining portions 112 and 113 joined to the second folder surface 12 and a free end lower opening 114 And the nose clip 115 is inserted at an appropriate position. The bonding is generally performed by ultrasonic bonding.

The second folder surface 12 has an upper joint portion 121 and first and second side joint portions 122 and 123 which are joined to the first folder surface 11 and first and second side end openings 124 , 125, first and second lower openings (126, 127), and a cutout (128).

Each of the upper joining portion 111 and the first and second side joining portions 112 and 113 of the first folder surface 11 is connected to the upper joining portion 121 and the first and second side joining portions 121 and 113 of the second folder surface 12 122 and 123, and the joining structure of the joining portions of the first folder surface 11 assists the lower opening 114 to have a structure that can be folded and unfolded as free ends.

At this time, the point a and the point b are pulled to each other, so that the first lower surface opening 126 and the second lower surface opening 126 are smoothly joined together. The second lower surface openings 127 are connected to each other and the first and second lower surface openings 126 and 127 have a three-dimensional curvature instead of a straight line.

The left and right first and second side openings 124, 125 of the second folder surface 12 constitute the side openings as free ends.

The first folder surface 11 constitutes an upper surface, and the second folder surface 12 constitutes a central surface and a lower surface of the second folder surface 12. In other words, the first and second folder surfaces 11 and 12 are joined by using the two first and second folder surfaces 11 and 12, So that a foldable mask having a cup-shaped or dome-shaped predetermined space can be formed as a whole.

FIG. 2 is a front view of the folding type dustproof mask according to the present invention, and FIG. 3 is a rear view of the folding type dustproof mask according to the present invention when viewed from inside.

2 and 3, the foldable mask 10 of the present invention has a structure in which the upper face joints 111 and 121 of FIG. 1 are sandwiched between the first and second side joints 112, 113, 124 and 125 And a cup-shaped or dome-shaped space is ensured by the housing strength portion 216 according to the forced joining of the cut-out portion 128. [0051]

The first folder surface 11 has a top surface 11b that is folded and unfolded without being joined to the abutment surface 11a to be joined to the second folder surface 12. [ The joining face 11a is divided by the upper end joining line 213 and the joining line 214. The upper end face 11b is folded and unfolded by the upper joining line 213. [

The second folder surface 12 is forcibly formed into a three-dimensional shape by the housing force portion 216 and is divided into a center surface 12a and a bottom surface 12b.

The housing strength portion 216 is formed by being gathered along the both front end lines of the cutout portion 128, and the gathered portion is formed on the outer side of the mask so that the projections on the inner side of the mask are removed to improve the fit feeling .

The housing strength portion 216 is formed only on the side of the lower end face 12b so as to partition the center face 12a and the lower end face 12b. That is, when the incision portion 128 is formed, (128).

As a result, the length of the housing strength portion 216 determines the width size of the center face 12a and the bottom face 12b.

The length W2 of the housing strength portion 216 is preferably equal to or less than 1/2 of the width W of the second folder surface 12 and the length W2 of the housing strength portion 216 is equal to or greater than the width W2 of the center face 12a Is always smaller than the width W1.

This is because in the mask formation, the center face 12a forms the front face portion of the mask and the lower end face 12b formed with the upper face 11b and the housing force portion 216 form a three-dimensional mask in the form of an upper and lower wing. So that the lower end face 12b is prevented from protruding outside the center face 12a when folded together.

The lower end face 12b may be formed with a lower end contact wire 211 in order to improve the foldability when the mask is folded.

A longitudinal axis connecting wire 215 may be formed at the central longitudinal axis of the center face 12a so as to be in close contact with the face during wearing.

On both sides of the center face 12a, hook portions 212 that can be hooked to the ear can be formed.

4 is a plan view of the folding type dustproof mask according to the present invention.

As shown in FIG. 4, the foldable mask 10 of the present invention has a first folded surface 11 and a second folded surface 12 joined together, And the lower end face 12b is also folded on the inner side face of the center face 12a with respect to the lower end furring line 211 as the inner folding line 12a.

That is, the top end portion is joined using the two faces of the first folder surface 11 and the second folder surface 12 of FIG. 1 and the cutout portion 218 of the bottom end portion is forcedly joined to form the housing strength portion 216, It can be used as a cup-shaped or dome-shaped mask having a predetermined space defined by three surfaces when it is folded and used when it is not used by forming three surfaces of the surface 11b, the central surface 12a and the bottom surface 12b do.

FIG. 5 is a perspective view of a folding type dustproof mask according to another embodiment of the present invention, and FIG. 6 is a plan view of the dustproof mask in a reverse direction of FIG.

5 is a perspective view of a portion seen from the outside when worn on the face of a person, and Fig. 6 is a plan view showing a folded state on the opposite side thereof, but not in an unfolded state.

The folder type dustproof mask 20 shown in Figs. 5 and 6 is composed of the same two folding faces 11 and 12 as shown in Fig. 1, and is denoted by different reference numerals for convenience of explanation.

As shown in FIGS. 5 and 6, the foldable mask 20 of the present invention has a structure in which the upper face joints 111 and 121 of FIG. 1 are sandwiched between the first and second side joints 112, 113, 124 and 125 And a cup-shaped or dome-shaped space is ensured by the housing strength portion 216 according to the forced joining of the cut-out portion 128. [0051]

The first folder surface 51 has a joining surface 51a to be joined to the second folder surface 52 and a top surface 51b that can be folded and unfolded.

The second folder surface (52) is formed into a three-dimensional shape by the housing force portion (516).

The housing strength portion 516 is formed by being gathered along the both front end lines of the cutout portion 128 and is joined to the outside of the mask so that the projections and the like of the joining portion are removed from the inside of the mask .

The housing strength portion 516 is formed only on the side of the lower end face 52b so as to partition the center face 52a and the lower end face 52b, that is, in the portion where the lower end face 52b is formed when the incision portion 128 is formed, (128).

As a result, the length of the housing strength portion 516 determines the width size of the center face 52a and the bottom face 52b.

The center face 52a and the lower end face 52b are not physically separated but are formed by curving the two faces at an angle while forming an inner space by the housing strength portion 516 on one face. And the bottom surface.

6, the second folder surface 52 is folded so that the lower end surface 52b abuts against the inner surface of the center surface 52a, and the lower end surface 52b of the second folder surface 52 is joined to the opposite ends of the center surface 52a and the lower end surface 52b, . The junctions at both ends may be referred to as junctions 53 at both ends.

The reason for the double-end joint 53 is as follows. When the mask is worn to cover the nose and mouth of a person, it is hooked to the ear using both hooks. At this time, although the mask may be lifted at an angled portion between the bottom of the ear and the jaw, when the mask is unfolded, it is pulled from both sides of the lower end surface by the end joints 53 and the curved surface of the lower end is tightened, The effect is brought close to the face between the bottom of the ear and the jaw, thereby assisting the function as a mask.

7 is a plan view of a folder type dustproof mask according to another embodiment of the present invention when it is not used.

As shown in FIG. 7, the folding type dustproof mask 50 of the present invention can be folded at half the length of the vertical center line when not in use, as shown in the figure.

The folding type dustproof mask 50 according to another embodiment of the present invention is structured such that both ends thereof are joined by the both end joining parts 53, so that both ends are raised when folded as shown in Fig. 4, 7, the structure can be folded symmetrically with respect to the vertical center line.
