1 to 4 are views for explaining the structure of a waterproof mask according to the present invention.

Referring to FIG. 1, the waterproof mask 1 according to the present invention may include a main body part 1A and a string part 1B.

The body portion 1A can sufficiently block dust, for example, fine dust, and may have a waterproof function.

The body part 1A may include a left part 10 and a right part 11.

The left part 10 may correspond to the right face of the mask wearer. In other words, the left portion 10 may cover or cover at least a portion of the mask wearer's right face.

The right part 11 may correspond to the left face of the mask wearer.

Here, the left part 10 and the right part 11 are divided from the observer's point of view, and the present invention may not be limited thereto.

The reason for dividing the body portion 1A into the left portion 10 and the right portion 11 will be sufficiently understood through the following description.

The string part 1B may be disposed on both sides of the main body part 1A to correspond to the user's ears.

The user can wear the waterproof mask 1 according to the present invention in the form of hanging the string part 1B on both ears and covering the mouth using the body part 1A.

As shown in FIG. 2, when looking at the cross section of the waterproof mask 1 cut along the line A1-A2, the main body 1A of the waterproof mask 1 has an outer layer 110 and an inner layer Layer, 120) and a vinyl layer (Vinyl Layer, 100).

In this case, the string part 1B may be connected to the outer skin layer 110 of the main body part 1A.

The skin layer 110 may be a surface facing the outside. This outer skin layer 110 may be exposed to the outside.

The outer skin layer 110 can suppress (prevent) foreign matter such as dust from the outside.

To this end, the outer skin layer 110 may include a water repellent that can prevent adsorption of moisture. From another point of view, the skin layer 110 may include fibers containing a water repellent.

Alternatively, the skin layer 110 may also include fibers containing a water and oil repellent agent to prevent adsorption of oil as well as moisture.

For example, the outer skin layer 110 includes at least one of a fluorine-based water repellent agent, a silicone-based water repellent agent, an acrylic-based water repellent agent, a polyethylene-based water repellent agent, a polypropylene-based water repellent agent, a polyamide-based water repellent agent, a polyester-based water repellent agent, and a polymethyl-based water repellent agent. can do.

The endothelial layer 120 may face the user's side, that is, the inside.

Here, the outer skin layer 110 side is referred to as 'outside' and the inner skin layer 120 side is referred to as 'inside', but this is set to aid understanding, and the present invention may not necessarily be limited thereto.

The vinyl layer 100 may be disposed between the outer skin layer 110 and the inner skin layer 120 .

The endothelial layer 120 may include a portion in direct contact with the user's skin. Accordingly, the density of the inner skin layer 120 may be sufficiently large for a user's comfortable touch.

In detail, the density of the inner skin layer 120 may be greater than that of the outer skin layer 110 .

The thickness T2 of the inner skin layer 120 may be thinner than the thickness T1 of the outer skin layer 110 . In this case, a more comfortable tactile feeling may be provided to the user.

As shown in (A) and (B) of FIG. 3 , the size of the opening OP2 of the inner skin layer 120 may be smaller than the size of the opening OP1 of the outer skin layer 110 . From another point of view, the aperture ratio of the inner skin layer 120 may be smaller than that of the outer skin layer 110 . In this case, a more comfortable tactile feeling may be provided to the user.

The vinyl layer 100 mainly performs a waterproof function, and may have a sufficiently thin thickness. Considering this, the thickness T3 of the vinyl layer 100 may be thinner than the thickness T1 of the skin layer 110 . In addition, the thickness T3 of the vinyl layer 100 may be thinner than the thickness T2 of the inner skin layer 120 .

The vinyl layer 100 can also perform an antibacterial function in addition to a waterproof function. To this end, the vinyl layer 100 may include a water quality material and an antibacterial material.

The antibacterial material applied to the vinyl layer 100 may be a powder type copper material.

Referring to Figure 4, the waterproof mask 10 according to the present invention may further include a middle layer (Middle Layer, 130).

The intermediate layer 130 is disposed between the outer skin layer 110 and the inner skin layer 120, and may be adjacent to the vinyl layer 100.

The intermediate layer 130 can improve the overall strength of the waterproof mask 1 and protect the vinyl layer 100 from damage.

Since the middle layer 130 is located between the outer skin layer 110 and the inner skin layer 120, it may have a relatively low density or a relatively thin thickness.

Considering this, it is possible that the density of the middle layer 130 is lower than the density of the inner layer 120 and/or the density of the outer layer 110 . In addition, the thickness of the middle layer 130 may be thinner than the thickness T1 of the skin layer 110 .

Alternatively, from the viewpoint of strongly protecting the vinyl layer 100, the density of the intermediate layer 130 may be higher than that of the skin layer 110.

In this case, the middle layer 130 may be made of the same material as the endothelial layer 120 . In addition, the density of the middle layer 130 and the density of the endothelial layer 120 may be the same or sufficiently similar to the same level.

As such, when the middle layer 130 and the inner skin layer 120 are manufactured using the same material, the manufacturing cost of the waterproof mask 1 can be reduced.

As shown in FIG. 4 , the intermediate layer 130 may be positioned between the vinyl layer 100 and the skin layer 110 .

In this case, the intermediate layer 130 can sufficiently protect the vinyl layer 100 from heat or shock applied in the direction of the outer skin layer 110 .

Alternatively, under the condition that the thickness T1 of the outer skin layer 110 is sufficiently thick, the middle layer 130 may also be positioned between the vinyl layer 100 and the inner skin layer 120.

The detailed configuration of the waterproof mask 1 having this structure is described in detail in relation to the manufacturing method of the waterproof mask 1 as follows.

5 to 22 are diagrams for explaining the detailed configuration of a method for manufacturing a waterproof mask and a waterproof mask according to the present invention. Hereinafter, description of the parts described in detail above may be omitted.

Referring to FIG. 5, in order to manufacture the waterproof mask 1, first, a fabric may be input (S100).

Thereafter, a seam part 150 may be inserted between the input fabrics (S200).

Thereafter, while cutting the input fabric, the cut fabric may be primarily thermally bonded together with the cut fabric (S300).

Thereafter, the left portion 10 and the right portion 11 may be thermally bonded (secondary thermal bonding) in the cut fabric (S400).

After that, the string part 1B may be bonded to the outer skin layer 110 . In detail, the string portion 1B may be bonded to the outer skin layer 110 by thermal bonding.

6 shows an example of a cylindrical mold (Mold, 140).

A mask pattern 141 corresponding to the waterproof mask 1 may be formed on the surface of the mold 140 .

The mask pattern 141 may correspond to at least one mark engraved on the surface of the waterproof mask 1 .

In addition, the mask pattern 141 may correspond to a joint part, which is a part where the outer skin layer 110, the inner skin layer 120, the vinyl layer 100, and the intermediate layer 130 of the waterproof mask 1 are joined. there is.

Marks and junctions can be more clearly explained through the following description.

A cutout 142 corresponding to an edge of the waterproof mask 1 may be installed on the surface of the mold 140 .

A heat sufficient to sufficiently bond the outer skin layer 110, the inner skin layer 120, the vinyl layer 100, and the intermediate layer 130 may be applied to the cylindrical mold 140.

Referring to FIG. 7 , the first, second, third, and fourth fabrics 100a, 110a, 120a, and 130a necessary for manufacturing the waterproof mask 1 may be put into the cylindrical mold 140.

The first fabric 100a may be a fabric for manufacturing the vinyl layer 100 .

The second fabric 110a may be a fabric for manufacturing the outer skin layer 110 .

The third fabric 120a may be a fabric for manufacturing the endothelial layer 120 .

The fourth fabric 130a may be a fabric for manufacturing the intermediate layer 130 .

In the course of inputting the first, second, third, and fourth fabrics 100a, 110a, 120a, and 130a, it is possible to insert the core portion 150 between two adjacent fabrics. In detail, the core 150 may be inserted between two adjacent fabrics in the direction of the rotational axis of the mold 140 .

Here, the mold 140 may be heated to a predetermined temperature and rotated by rotational force provided by a predetermined motor (not shown) or the like.

In this case, the first, second, third, and fourth fabrics 100a, 110a, 120a, and 130a are formed on the surface of the mold 140 by the cut portion 142 formed on the surface and the heat applied to the mold 140 to form the waterproof mask 1. It can be cut and cut according to the shape.

The first, second, third, and fourth fabrics 100a, 110a, 120a, and 130a cut to correspond to the shape of the waterproof mask 1 may be referred to as mask intermediate members 1Aa (hereinafter referred to as 'intermediate materials'). there is.

Intermediate material (1Aa) can be seen as a step before the waterproof mask (1) is completed.

In order to form a mark such as a logo on the surface of the outer skin layer 110, it is possible to put the second fabric 110a in contact with the mold 140.

In this case, heat generated in the mold 140 may be transferred to the first original fabric 100a serving as a raw material of the vinyl layer 100 through the second fabric 110a.

In order to minimize the heat transferred to the second fabric 110a and make the inner skin layer 120 the surface in contact with the user's skin, a second fabric 120a is placed between the first fabric 100a and the mold 140. ) and the fourth raw material 130a.

In this case, the intermediate layer 130 may be positioned between the vinyl layer 100 and the skin layer 110 in the waterproof mask 1 .

An example of the intermediate member 1Aa is shown in FIG. 8 .

Referring to FIG. 8 , the intermediate member 1Aa may be divided into a left portion 10 and a right portion 11 as a whole.

In this case, as shown in FIG. 9 , the outer skin layer 110, the inner skin layer 120, the vinyl layer 100, and the intermediate layer 130 may be divided into a left portion and a right portion, respectively.

When the edges of the outer skin layer 110, the inner skin layer 120, the vinyl layer 100, and the intermediate layer 130 shown in FIG. 9 are thermally bonded, the intermediate member 1Aa may be formed.

Referring to FIG. 10 , the vinyl layer 100 may include at least one opening OP.

The opening OP formed in the vinyl layer 100 may be larger than the opening OP1 of the skin layer 110 .

In this case, the waterproof mask 1 can have sufficient waterproof performance and allow the user to breathe smoothly.

As shown in (A) of FIG. 10 , the openings OP in the vinyl layer 100 may be evenly distributed throughout.

Alternatively, as shown in (B) of FIG. 10 , at least one opening OP is formed in the left and right side regions of the vinyl layer 100, and the opening OP is formed in the central region of the vinyl layer 100. It may not be.

Here, the central area of the vinyl layer 100 may be an area where the user's breathing is mainly performed.

Referring to FIG. 8 again, at least one joint part 160 may be formed on the surface of the intermediate member 1Aa. From another point of view, at least one bonding portion 160 may be formed on the surface of the waterproof mask 1 (the surface of the outer skin layer 110).

The process of forming the bonding portion 160 may be referred to as a primary thermal bonding process.

The joint portion 160 may include a first joint portion 161 , a second joint portion 162 , a third joint portion 163 , and a fourth joint portion 164 .

The first joint portion 161, the third joint portion 163, and the fourth joint portion 164 may be regarded as predetermined marks (Mark, M).

The bonding portion 160 and/or the mark M may be formed by bonding the outer skin layer 110, the inner skin layer 120, the vinyl layer 100, and the intermediate layer 130 by heat.

In detail, the bonding portion 160 and/or the mark M may be formed by pressing toward the inner skin layer 120 from the outer surface of the outer skin layer 110 by the mold 140 .

The first joining portion 161 may be used to join the string portion 1B. Considering this, the first bonding portion 161 may be referred to as a kind of alignment mark for bonding between the string portion 1B and the outer skin layer 110 .

Accordingly, the first bonding portion 161 may be referred to as a string mark corresponding to the string portion 1B.

The second bonding portion 162 may have a line shape having a relatively long length. The second bonding portion 162 may more strongly adhere the outer skin layer 110 , the inner skin layer 120 , the vinyl layer 100 and the intermediate layer 130 .

The third bonding portion 163 is formed on the edge of the middle member 1Aa (the edge of the waterproof mask 1) to seal the edge of the middle member 1Aa (the edge of the waterproof mask 1).

The fourth joint portion 164 may be a kind of logo.

The waterproof mask 1 according to the present invention may also include other joint portions in addition to the first, second, third, and fourth joint portions 161, 162, 163, and 164.

Even in a state where the waterproof mask 1 is manufactured from the intermediate member 1Aa, the left portion 10 and the right portion 11 can be distinguished.

The left portion 10 and the right portion 11 may be integrally formed.

Between the left part 10 and the right part 11, a bridge part 13 connecting the left part 10 and the right part 11 may be located.

The leg portion 13 may correspond to the user's nose. In detail, while the user is wearing the waterproof mask 1, the leg portion 13 of the waterproof mask 1 can cover the user's nose.

The core portion 150 having a bar shape may be disposed in a shape crossing the leg portion 13 . Accordingly, the leg portion 13 may correspond to the middle portion of the core portion 150 .

Looking at the cross section taken along the line B1-B2, as in the case of FIG. 11, the core 150 may be disposed between the outer skin layer 110 and the inner skin layer 120.

For example, as shown in (A) of FIG. 11 , a core portion 150 may be disposed between the skin layer 110 and the intermediate layer 130 .

In this case, it is possible to suppress or prevent the vinyl layer 100 from being damaged by the core 150 including a hard material.

Alternatively, as shown in (B) of FIG. 11, it is also possible that the core portion 150 is disposed between the intermediate layer 130 and the vinyl layer 100.

Referring to FIG. 12 , the seam part 150 may include a first seam part 151 and a second seam part 152 corresponding to the first seam part 151 .

The first core portion 151 may correspond to the left portion 10 of the waterproof mask 1, and the second core portion 152 may correspond to the right portion 11.

It is possible that the first core portion 151 and the second core portion 152 have sufficiently large strength, elasticity, and restoring force.

The first core portion 151 and the second core portion 152 can sufficiently withstand external force without being bent. Even if the first core part 151 and the second core part 152 are bent by an external force, they can be restored again when the applied force is removed.

In this case, a sufficient space through which air can flow may be provided between the first core portion 151 and the second core portion 152 and the user's face while the user is wearing the waterproof mask 1 .

Accordingly, the waterproof mask 1 according to the present invention can enable the user to breathe smoothly while implementing the waterproof function.

The core 150 may include any material as long as it can provide sufficiently high elasticity. In detail, considering manufacturing cost, elasticity, strength, and the like, the core 150 may include a plastic material.

The first core 151 and the second core 152 may be disposed to cross each other at a first angle θ1.

For example, it is possible to form the first core portion 151 and the second core portion 152 by bending the bar-shaped mother core portion at a first angle θ1.

The first core 151 and the second core 152 may be connected.

For example, as shown in (A) of FIG. 13 , the core part 150 may include a first core part 151 , a second core part 152 and a middle part 153 .

The middle portion 153 may be disposed between the first core portion 151 and the second core portion 152 and connect the first core portion 151 and the second core portion 152 .

Here, the thickness T22 of the middle portion 152 may be thinner than the thicknesses T21 of the first core portion 151 and the second core portion 152 .

In this case, while the first core portion 151 and the second core portion 152 each have sufficient elasticity and restoring force, the angle between the first core portion 151 and the second core portion 152 is increased due to external force. It may be possible to vary easily.

Alternatively, as shown in (B) of FIG. 13 , the first core portion 151 and the second core portion 152 may be separately divided.

Even in this case, the angle between the first core portion 151 and the second core portion 152 due to the force applied from the outside while the first core portion 151 and the second core portion 152 each have sufficient elasticity and restoring force. It may be possible that is easily varied.

Referring to (A) of FIG. 14 , a first area AR1 may be provided on the left portion 10, and a second area AR2 corresponding to the first area AR1 may be provided on the right portion 11. there is.

Here, the leg portion 13 may be folded so that the left portion 10 and the right portion 11 overlap.

Then, as shown in (B) of FIG. 14 , at least a portion of the first area AR1 of the left portion 10 and the second area AR2 of the right portion 11 may overlap each other.

In this way, pressure and heat may be applied to the first area AR1 and the second area AR2 in a state where the left portion 10 and the right portion 11 are folded.

Then, as shown in FIG. 15 , the first area AR1 and the second area AR2 are bonded by heat to form a new bonding portion 165 .

The junction part 165 formed through this process may be referred to as a central joint part 165, which is a part where the left part 10 and the right part 11 are thermally bonded.

The bonding portion 160 corresponds to the bonding portion 160 because the outer skin layer 110, the inner skin layer 120, the vinyl layer 100, and the intermediate layer 130 are bonded by heat in the width direction. The thickness of the body portion 1A in the region may be relatively thin.

For example, as shown in (A) and (B) of FIG. 16, the thickness of the body portion 1A in the area where the first bonding portion 161 is formed is the first bonding portion 161 in the peripheral area. It may be thinner than the thickness of the body portion 1A.

Referring to FIG. 17, a string joint part 166 corresponding to the string part 1B may be formed on the surface of the outer skin layer 110 of the body part 1A of the waterproof mask 1.

The string junction 166 may be referred to as a kind of junction part 160 as a part where the string part 1B and the outer layer 110 are joined.

An example of a method of forming the string joint 166 is shown in FIG. 18 .

As shown in FIG. 18, a part of the string part 1B may be disposed on the upper part of the skin layer 110 of the main body part 1A.

In this state, heat and pressure may be applied to the upper part of the string part 1B by using the press PP having the first width W1.
