Description

Mask with separated hangers

Technical Field

The present invention relates to a mask which stably covers a nose and a mouth of a wearer and continuously filters air inhaled through the nose and the mouth, and more particularly, to a mask having a separable ear hanging cord, which is manufactured to be capable of separating the ear hanging cord from a mask body and reusing the ear hanging cord in a new mask body.

Background

Generally, a mask is an article that covers the nose and mouth of a wearer in order to hygienically prevent inhalation and scattering of germs, dust, and the like. This mask was developed for the purpose of preventing the occurrence of a phenomenon that the probability of infection with influenza increases by reducing the resistance of the nasal cavity or the oral cavity when a person inhales cold air from the time of occurrence of influenza, which is a spanish cold that prevails in 1919. In the case of the mask developed in the early stage, cold air can be prevented from flowing into the nasal cavity or oral cavity of a human, but viruses or bacteria contained in the air cannot be screened, and influenza cannot be prevented.

Then, various technologies have been developed, and a filter cotton having an antibacterial function of screening viruses or bacteria contained in the air has been developed, so that flu is prevented, but actually, with the industrial development, environmental pollution such as air, water, soil, etc. occurs, and the air is polluted by substances having a particle size of less than 10, such as sulfur dioxide gas, nitrogen oxides, lead, ozone, carbon monoxide, fine dust, etc.

Thus, it is difficult to artificially remove the pollutants such as fine dust, which have been contained in the air, and a technology for filtering the pollutants contained in the air has been developed. In particular, in the case where a person performs an external activity, pollutants such as fine dust are directly inhaled, and a mask covering the nose and mouth and filtering the pollutants through filter cotton has been developed.

Generally, a mask comprises: a mask body part which is mounted on the face of a wearer in such a manner that the inner side surface covers the nose and mouth of the wearer, and into which air flows from the outside; and ear hanging ropes combined with the left side and the right side of the mask main body part and hung on ears of a wearer. That is, the ear hanging string is hung on the ear of the wearer to provide a function of preventing the mask body from slipping off the face of the wearer. However, depending on the size of the face of the wearer wearing the mask, the mask body portion may press the face of the wearer due to the length of the ear hanging string being too short, which may cause inconvenience in wearing the mask, or may slip off the face of the wearer due to the length of the ear hanging string being too long, which may not be in close contact with the face of the wearer, thereby causing the external air to flow directly into the nose and mouth of the wearer.

Recently, new coronavirus pneumonia-19 (COVID-19) has occurred worldwide, using millions of masks in a day and then thrown away.

In particular, for the production of the electrostatic filter constituting the mask, a melt-blowing method is used in which a compressed polypropylene (PP) solution is sprayed through a high-temperature, high-pressure nozzle to which a high voltage (+) is applied, to produce a nonwoven fabric having a random mesh pattern with a nanometer thickness.

Therefore, the mask body is made of PP (polypropylene) as a main material, but the ear hanging ropes are made of a material different from that of the mask body, so that the mask which is not reusable and is thrown away needs to be disposed of by burning and the like, and a large amount of fine dust is generated.

Further, since there are a lot of failures in the ear hanging cord when manufacturing the mask and a lot of manufacturing time is required when attaching the ear hanging cord to the mask body in the total time of manufacturing the mask, it is required to develop a mask in which the ear hanging cord can be reused in order to increase the production speed of the mask and reduce the failure rate of the mask.

Detailed Description

Hereinafter, a mask having a separable ear hanging string (hereinafter, referred to as "mask") according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view illustrating a first embodiment of a mask according to the present invention, fig. 2 is a perspective view illustrating a second embodiment of a mask according to the present invention, fig. 3 is a perspective view illustrating a third embodiment of a mask according to the present invention, and fig. 4 is a rear view illustrating a third embodiment of a mask according to the present invention.

Referring to fig. 1 to 4, the mask of the present invention includes: a mask body 100 covering the mouth and nose of the wearer; hangers rope 200 sets up respectively the left side and the right side of gauze mask main part 100 still include: the hanger rope connector 300 selectively connects both ends of the hanger rope 200. In this case, the mask body 100 has a cut line or a concave-convex portion for selectively detaching the ear hanging string 200 from the mask body 100.

The ear hanging rope is configured to have an open curve (open curve) structure as shown in fig. 1 and 2, or a closed curve (closed curve) structure as shown in fig. 3 and 4.

Hereinafter, each constituent element will be described in more detail with reference to the drawings.

Referring to fig. 1 to 4, the mask of the present invention includes: a mask body 100.

The mask body 100 is worn on the face of a wearer so as to cover the nose and mouth of the wearer, filters harmful substances such as fine dust contained in air flowing in from the outside direction, and allows only clean air to flow into the interior.

Therefore, the mask body 100 is formed by laminating two or more of cotton, synthetic resin, nonwoven fabric filter, synthetic resin filter, and electrostatic filter, respectively or in combination. For example, the mask body 100 may be composed of two or three nonwoven fabric filters, two nonwoven fabric filters and one electrostatic filter, or one nonwoven fabric filter and one electrostatic filter.

Here, the electrostatic filter is a filter electrostatically processed by an ultra high voltage current, and an electrostatic device captures fine dust having a polarity by a positive charge or a negative charge, thereby improving a dust-proof effect.

As a specific example, the mask body 100 of the present invention includes: the outer filter and the inner filter are used for smoothly flowing air and improving the cutting rate of filtering harmful substances such as fine dust, and a central filter is selectively arranged between the outer filter and the inner filter.

The outer filter cotton is used for enabling air flowing in from the outer direction to flow in from the inner direction, and has a waterproof function so as to prevent moisture from permeating. In this case, the outer filter can be formed of any fiber having a waterproof function, and for example, a synthetic fiber or a nonwoven fabric filter is used. Also, preferably, the outer filter is formed three-dimensionally in such a manner that sufficient air flows between the inner side surface of the inner filter and the wearer's face to make the wearer comfortable to breathe.

The inner filter is combined with the outer filter in a manner of being positioned on the inner side surface of the outer filter, covers the nose and the mouth of a wearer, and flows air flowing in through the outer filter in the inner direction, and has a waterproof function to prevent moisture from permeating. In this case, the inner filter can be made of any fiber having a waterproof function, and for example, a synthetic fiber or a nonwoven fabric filter is used.

The inner filter is manufactured by dividing the inner filter into upper and lower parts so as to form a space between the nose and mouth of the wearer, thereby making the wearer feel comfortable. That is, after the upper part and the lower part are divided and manufactured, the upper part and the lower part are joined to each other so as to form a predetermined angle, and the inner filter is not horizontally formed but formed in a circular shape or a zigzag shape in a side cross section.

Therefore, the inner filter forms a space between the nose and mouth of the wearer and the mask body 100, and an air layer is formed in the space, thereby facilitating the breathing of the wearer.

Between the outer and inner filter cloths is a nose bridge strip 160 deformed to correspond to the shape of the wearer's nose, as required. The nose bridge piece 160 may be formed of a metal wire or the like, which is deformed in accordance with the shape of the wearer's face so as to be in close contact with the inner surface of the inner filter and the wearer's face, and then maintains its outer shape.

That is, after the wearer brings the mask body 100 into close contact with the face, the wearer applies pressure to the nose bridge strip to deform the nose bridge strip in accordance with the shape of the nose of the wearer, thereby bringing the upper portion of the inner filter and the nose of the wearer into close contact, and completely cutting off the inflow of unfiltered air.

The nose bridge strip 160 is made of the same material as the mask body 100 as needed, and is reused together with the mask body 100.

The center filter is disposed between the outer filter and the inner filter to improve the filtering ability of the mask body 100, and may be formed of melt-blown filter (MB filter) or electrostatic filter. The central filter is constructed to have a double structure in which melt-blown filter and electrostatic filter are stacked as necessary.

Thus, when the inner filter is provided with a waterproof function, moisture contained in the breath is not transmitted to the center filter, thereby preventing the performance of the electrostatic filter from being lowered by the moisture.

As an embodiment, the mask body 100 of the present invention includes, as shown in fig. 4: a mouth patch 102 covering the mouth and nose of the wearer; a nasal patch 104 engaged with an upper portion of the mouth patch 102 to cover the nose of the wearer; and a chin patch 106 engaged with a lower portion of the mouth patch 102 to cover a wearer's chin.

The mouth patch 102, nose patch 104 and chin patch 106 are each composed of an outer filter and an inner filter, or an outer filter and a central filter and an inner filter, as described above.

As necessary, a bridge hanging portion 105 having a curved recess is formed in a portion of the nasal patch 104 contacting the nose of the wearer, and a chin hanging portion (not shown) having a curved recess is formed in a portion of the chin patch 106 contacting the chin of the wearer.

The mask body 100 is formed with an upper joining line 143 between the mouth piece 102 and the nose piece 104 and between the mouth piece 102 and the chin piece 106 by thermal welding, ultrasonic welding, or the like, and the nose piece 104 and the chin piece 106 are spread from the mouth piece 102 along the upper joining line 143 to expand the contact area covering the face.

The bonding wire 140 includes: a first edge join line 141 formed in a solid line or a wave line or a pattern along the edge of the mouth patch 102 between the nose patch 104; a second edge join line 142 is formed along the edge of the mouth patch 102 between the chin patch 106.

Also, the bonding wire 140 further includes: an upper joining line 143 which is formed below the first edge joining line 141 so as to extend the joining surface 150 between the mouth patch 102 and the nose patch 104 without passing air when the wearer breathes; and a lower joining line 144 which is formed above the second edge joining line 142 so as to be spaced apart from the second edge joining line 142 in such a manner that the joint surface 150 between the mouth patch 102 and the chin patch 106 is expanded without passing air when the wearer breathes.

The nose patch 104 is closely attached to the back of the mouth patch 102, and when the mask is used by the wearer, it is spread along the upper joining line 143 and closely attached to the nose and face of the wearer.

The chin patch 106 is in close contact with the back of the mouth patch 102 and when the mask is used by the wearer, it is spread along the lower joining line 144 to be in close contact with the wearer's chin and face.

Thus, the mask body 100 of the present invention is configured as a three-dimensional 3D mask including a mouth patch 102, a nose patch 104, and a chin patch 106.

In another embodiment, the mask body 100 of the present invention is formed in a flat type 2D mask structure.

As shown in fig. 3 and 4, in the case where the

ear hanging strings

210 and 220 are formed in a closed curve structure, the uneven portion 130 forms a hanging space from the edges of the left and right ends of the mask body 100 toward the inside of the mask body 100 so as to be wound around the left and right ends of the mask body 100. In other words, the concave-convex portion 130 provides a space around which the

ear hanging cords

210 and 220 pulled toward the ears of the wearer are wound according to the selection of the user.

More specifically, the concave-convex portion 130 includes a concave portion 132, a convex portion 134, and all. For example, as shown in fig. 2, the concave portion 132 is formed to be concave from the edges of the left and right ends of the mask body 100, and the convex portion 134 is formed to protrude from the edges of the left and right ends of the mask body 100.

Further, it is preferable that the cut line is provided on the joining surface 150 of the mask body 100 so as not to interfere with the movement of air during breathing of the wearer.

More specifically, the cut line is provided at the interface 150 between the mouth patch 102, nose patch 104, chin patch 106, or the interface between the outer and inner filter cloths.

In other words, the cut line is provided at the interface between mouth patch 102 and nose patch 104; the interface between the mouth patch 102 and the chin patch 106; more than one of the interfaces between mouth patch 102 and nose patch 104 and chin patch 106. In the case where the mask body 100 is formed as a flat 2D mask, the cut line is provided at a joint surface between the outer filter and the inner filter.

Fig. 5 is an exploded front view showing a fourth embodiment of the mask of the present invention, and fig. 6 is a front view showing a hanging string coupled to the mask body of fig. 5.

As a first embodiment, the cutting line of the present invention, as shown in fig. 5, includes: the hanging string 110 and the hanging string 115 are provided in the shape of a hanging piece inside the mask body 100 such that the ear strings 210 and 220 are wound around the left and right ends of the inside of the mask body 100. At this time, the hanging cut line 110 and the hanging cut line 115 are provided on the joint surface 150 of the mask body 100.

More specifically, the hanging string 110 may be temporarily provided on the surface of the mask body 100 with a hanger wound around the hanging

string

210 or 220 by an external force of a user so as to be fixed to the mask body 100 even in a state where the hanging

string

210 or 220 does not pass through the mask body 100.

For this reason, the hanging cut line 110 has an open curved structure so that the hanging member is not separated from the mask body 100. In other words, the hanging cut line 110 is omitted at the portion where the hanging piece is connected to the mask body 100.

The hanging cut line 110 is a line that cuts the outer shape of the hanger from the mask body 100 by an external force supplied by the user so that the hanger wound around the ear strings 210 and 220 protrudes from the mask body 100.

In the case where the hanging cut line 110 provides a profile around which the

lug cords

210, 220 are wound, it may have any profile. Specifically, the hanging cut line 110 has an arrow-shaped, triangular, quadrangular, circular, or the like structure.

The hanging cut line 110 is formed to be opposite to the adjacent hanging

ear strings

210 and 220 in such a manner that the hanging member is inserted into the hanging cut line 115 to be coupled and to perform the function of the hanging loop, as shown in fig. 5, and it is preferable that the hanging member is formed to be opposite to the hanging

ear strings

210 and 220 adjacent to the portion connected to the mask body 100.

One or more hanging cut lines 110 are provided at the right end of the mask body 100, and one or more hanging cut lines are provided at the left end of the mask body 100.

For example, in the case where the mask body 100 has two hanging strings at the left and right ends thereof, the first hanging string 210 is provided at the left end of the mask body 100 and wound around the two hanging strings forming the hanging loop, and the second hanging string 220 is provided at the right end of the mask body 100 and wound around the two hanging strings forming the hanging loop, as shown in fig. 6.

If necessary, in the case where two hanging strings 110 and two hanger strings 115 are vertically provided in the mask body 100, an auxiliary string 116 is provided between the hanging string and the hanging string or between the hanger string and the hanger string. The secondary cut line 116 is positioned at the engagement surface 150 to allow the wearer to manually adjust the length of the lug cord.

More specifically, as shown in fig. 6, the auxiliary cutting line 116 provides a passage in which one end of the ear string, which is disposed to entirely wrap the first hanging cutting line disposed at the upper end of the mask body 100 and the second hanging cutting line disposed at the lower end of the mask body 100, is inserted into a loop shape such as an 'Ω' shape.

Thus, when the wearer pulls the end of the lug rope passing through the auxiliary cutting line 116 as shown by the first lug rope 210 in fig. 6, the length of the lug rope wrapping the ear is shortened, and when the end of the lug rope is disposed so as not to pass through the auxiliary cutting line 116 as shown by the second lug rope 220 in fig. 6, the length of the lug rope wrapping the ear is increased.

As a second embodiment, as shown in fig. 1 and 2, the cutting lines according to the present invention include a plurality of ear hanging string cutting lines 120 formed at the left and right ends of the mask body 100 so that the both ends of the

ear hanging strings

210 and 220 are fixed to the left and right ends of the mask body 100 through the inside of the mask body 100.

More specifically, the ear strap slit line 120 temporarily provides a space through which the

ear strap

210 and 220 passes by the external force of the user so that the

ear strap

210 and 220 are fixed in a state of passing through the mask body 100.

When the supply of the external force is interrupted by the user, the string 120 for the ear string compresses the ear strings 210 and 220 inserted so as to penetrate the expanded space by reducing the expanded space, thereby providing pressure to keep the ear strings 210 and 220 coupled to the mask body 100.

For this purpose, the string-cutting line 120 is formed in a cross shape, a line shape, an arrow shape,

Glyphs, and the like. In this case, the straight line can also be formed as a 'straight' line or

A font.

For example, in the case where four ear hanging cord cutting lines 120 are provided at the right end of the mask body 100, the

ear hanging cords

210 and 220 are provided on the mask body 100 so that the ear hanging cord cutting lines abut on the ends of the

ear hanging cords

210 and 220, as shown in fig. 2.

Specifically, one end of the second strap 220 is passed through any of the first strap cutting line and the second strap cutting line, and the other end of the second strap 220 is passed through any of the fourth strap cutting line and the third strap cutting line. At this time, the first ear string cut line, the second ear string cut line, the third ear string cut line, and the fourth ear string cut line are arranged in the upper-lower direction of the plurality of ear string cut lines provided at the right end of the mask body 100.

Fig. 7 is an exploded front view showing a fifth embodiment of the mask of the present invention, and fig. 8 is an exploded front view showing a sixth embodiment of the mask of the present invention.

As shown in fig. 7 and 8, in the case where a plurality of ear hanging cord cutting lines 120 are provided at both ends of the mask body 100, the centers of the

ear hanging cords

210 and 220 are adjacent to the ear hanging cord cutting lines, and the

ear hanging cords

210 and 220 are provided on the mask body 100 so that the ends of the

ear hanging cords

210 and 220 are distant from the mask body 100. At this time, one end and the other end of the hanger rope 220 are fastened to each other to form a closed curve structure of the hanger rope, or a hanger rope connector 300 is provided between the one end and the other end to form a closed curve structure of the hanger rope.

For example, in the case where four ear string cutting lines 120 are provided at one end of the mask body 100, the second ear string 220 passes through the first ear string cutting line from the back surface of the mask body 100, and then passes through the second ear string cutting line at the front surface of the mask body 100. Further, the second strap 220 passes through the third strap cut line on the back surface of the mask body 100, and then passes through the fourth strap cut line on the front surface of the mask body 100.

As shown in fig. 8, in the case where three ear string cutting lines 120 are provided at one end of the mask body 100, an upper ear string cutting line is provided at an upper portion in a line shape, and an upper ear string cutting line is provided at a middle portion

The middle part of the shape is used as a cutting line for the hanger rope, and the lower part is provided with a 'straight' shape for the lower hanger rope. At this time, the ear string passes through the first ear string cut line at the rear surface of the mask body 100, and then passes through the second ear string cut line at the front surface of the mask body 100. Further, the ear strap has a loop structure such as an "Ω" shape on the rear surface of the mask body 100 so that the length of the ear strap can be adjusted by the wearer, and then passes through the second ear strap cut line again on the rear surface of the mask body 100 and passes through the third ear strap cut line on the front surface of the mask body 100.

Thus, in the case where the ear hanging cord is combined with the mask body 100 in a manner of passing through the plurality of ear hanging cord cutting lines provided at the mask body 100, both side ends of the mask body 100 are sewn as if the ear hanging cord is used, thereby providing an effect of reducing the air leakage rate of the mask.

As a third embodiment, as shown in fig. 3, the cutting lines according to the present invention include length-adjusting cutting lines 125 formed at both ends of the mask body so that one ends of the

ear hanging lines

210 and 220 pass through the mask body 100 to adjust the ear hanging lines.

In the mask body 100 of the present invention, a receiving opening or a multi-purpose cutting line is provided on the inner surface or the outer surface of the mask body 100 so that a spacer is inserted as required.

The multi-purpose cutting line is a structure in which a plurality of spacers for providing additional functions are inserted into the joint surface 102.

As a specific example, the multi-purpose cutting lines of the present invention are formed in a single piece on each of four sides of a diamond edge line on the surface of the mask body 100 so as to be inserted into the apex portion of a spacer having a quadrangular structure.

More specifically, the multi-purpose cutting line comprises: a first multipurpose cutting line provided at an upper portion of a left end of the mask body 100; a second multi-purpose cutting line at a lower portion of the left end; a third multipurpose cutting line provided at an upper portion of a right end of the mask body 100; and a fourth multipurpose cutting line provided at a lower portion of the right-side end. At this time, the second multi-purpose cutting line is laterally symmetrical to the first multi-purpose cutting line, and the third multi-purpose cutting line is vertically symmetrical to the first multi-purpose cutting line. For example, the multi-purpose cut line has a length of 5 mm to 20 mm.

The pad is a functional pad such as a propaganda pad, a humidifying pad, an aromatic pad, an oxygen pad, and a deodorizing pad.

Here, the functional mat means a mat used for a special purpose in daily life or sleeping. For example, the humidification pad prevents the problem of pain caused by dry throat in the case where a rhinitis patient breathes in the mouth while breathing through the nose is difficult when sleeping. A pad for absorbing a liquid containing a green tea component or a chamomile component having a good humidification effect is used as the humidification pad.

A pad that absorbs essential oil-containing liquid for resting and skin-care purposes is used as the fragrant pad.

A gasket coated or impregnated with oxygen powder is used, and a gasket having oxygen particles attached or embedded therein is used as the oxygen gasket.

A pad coated or impregnated with or incorporating a deodorizer that adsorbs harmful gases or odors is used as the deodorizing pad.

The functional pad may be used by inserting a multi-purpose cutting line into one end thereof, but the functional pad may be built in by providing the cutting line with a level of accommodating the gasket in the inner filter or the outer filter.

Therefore, the propaganda pad of the invention combines various functional pads such as a humidifying pad, an aromatic pad and the like with the mask for the purpose of treatment or body-building.

Fig. 9 is an exploded front view showing a seventh embodiment of the mask of the present invention, and fig. 10 is a perspective view showing the seventh embodiment of the mask of the present invention.

As a specific example, the mask body 100 of the present invention has a close contact member.

The close fitting members temporarily reduce the vertical lengths of both ends of the mask body 100 so that the left end and the right end are not spaced apart from the face of the wearer when the mask body 100 is worn on the face of the wearer, thereby providing an effect of closely fitting both ends of the mask body 100 to the face of the wearer.
