Description

mask {Mask}

The present invention relates to a mask and a method for manufacturing the same, and more particularly, it is possible to prevent the mask from adsorbing to the mouth and nose during breathing by improving the mask shape maintaining function while retaining the wearing convenience by using a thin fabric. A mask and its manufacturing method that can bond the center of the mask using an adhesive method instead of sewing, maximize the mask's shape retention force, and provide an optimal adhesive thickness that does not distort the mask adhesive part from side to side. it's about

Generally, a mask has the purpose of covering an object or protecting the object from various internal and external factors, and there are often a mask for heat preservation, a health mask, a dust mask, and a gas mask.

The double health mask uses a specially manufactured fabric to block various viruses that are spread in the air or spread through droplets. However, the health mask has a problem in that it is avoided to wear because the thickness of the mask increases as the blocking function is increased, so that the breathability is lowered and breathing becomes difficult.

In particular, in a situation where regular wearing of a mask is compulsory due to the recent outbreak of the Corona 19 virus, in the summer when the temperature is high, the thickness of the mask becomes thin due to problems such as breathing difficulties or a mask with a weakened droplet blocking function such as a dental mask There is a problem in that the original purpose of the mask is weakened in this case.

In addition to the functional problem of the mask, when the fabric of the mask is thinned, the shape retaining power of the mask is lowered when worn, so that a space for breathing between the mouth or nose is not well formed. There is a problem that it becomes more difficult to breathe because of the tightness.

In addition, when manufacturing a mask, a method of sewing the middle part after cutting the fabric in a developed shape is generally used, but in the case of sewing, a space may occur in the part through which the thread passes from the fabric, so there is a problem that the blocking power of the virus is lowered. .

Hereinafter, with reference to the drawings, a mask and a method for manufacturing the same according to the present invention will be described in detail.

The mask 1 according to an embodiment of the present invention has a mask body 11 and 21 and earring portions 13 and 23, respectively, and a pair of first mask portions 10 provided in a mutually symmetrical shape, and Including the second mask part 20, it is connected in the central vertical central part 30 to form a three-dimensional shape covering at least the mouth and nose of the wearer, and the vertical central part 30 is the extension part 31 and the lower adhesive part (331).

Prior to the description, since the present invention has a main feature in the vertical central portion 30 as shown in FIG. 3 , the shape or material of the mask body 11 , 21 or the earring portions 13 and 23 , etc., except for this, are various Modifications are possible, and even those not shown or described in the drawings for these parts are included in the scope of the present invention, of course.

Each configuration will be described in detail.

1 is an exploded view of a mask 1 according to an embodiment of the present invention.

Referring to the drawings, the first mask portion 10 and the second mask portion 20 having mutually symmetrical shapes are provided to the left and right around the central extension 31 .

Each of the first mask unit 10 and the second mask unit 20 includes a mask body 11 and 21 and earring parts 13 and 23, and the mask body 11 and 21 is a wearer's mouth and nose. And it is provided in a size that can cover the ball portion, the earring portions 13 and 23 extend from the ends of the mask body 11, 21 so that the mask body 11, 21 can be hung on the wearer's ear. The earring portions 13 and 23 may be provided to extend integrally from the mask body 11 and 21 as shown in FIG. 1 , but may be provided in various ways, such as separately manufactured and fixed.

As shown in FIG. 2, the first mask unit 10 and the second mask unit 20 are preferably provided in a shape symmetrical to the left and right about the vertical central part 30, but are not limited thereto. Of course, it may be provided in different shapes depending on the

Therefore, when manufacturing the mask 1 according to the present invention, after cutting the fabric in the shape shown in FIG. 1 , an adhesive is applied to the lower adhesive part 331 and the upper adhesive part 311 to be described later (or adhesion of a previously prepared shape). After adhering the tape), the mask can be manufactured through a simple step of folding into the shape shown in FIG. 2 , thereby maximizing productivity by minimizing the number of manufacturing processes and processing time.

Meanwhile, the vertical central part 30 includes an extension part 31 and a lower adhesive part 331 .

As shown in FIG. 3 , the vertical central part 30 forms the center of the mask 1 , and the first mask part 10 and the second mask part 20 are combined to form a three-dimensional shape.

The extension part 31 extends the first mask part 10 and the second mask part 20 integrally.

The extension part 31 may be provided in various lengths, for example, may have a length corresponding to the length of a typical wearer's reference nose.

As shown in FIG. 1 , the extension part 31 may be provided integrally with a single fabric, but when the first mask part 10 and the second mask part 20 are separately manufactured, adhesive or other methods are used. It is also possible to combine them in this way.

In the case where the extension part 31 is integrally formed as in the former case, as shown in FIG. 2 , in the state where the first mask part 10 and the second mask part 20 are adhered and folded, the shape of a straight line is obtained. will achieve

The lower adhesive part 331 is provided at the lower portion of the extension part 31 , and the cutout part 33 ends of the first mask part 10 and the second mask part 20 are adhered to each other with a set uniform adhesive width.

The lower adhesive part 331 is formed along the cutout 33 of the first mask part 10 or the second mask part 20 .

Here, the uniform adhesive width means that the adhesive force is uniformly maintained to have a uniform shape retaining force along the entire length of the lower adhesive part 331, and does not mean only the numerically identical width (this is due to the manufacturing process) may be impossible), even if a numerical error occurs locally, it should be interpreted as including maintaining the adhesive force evenly throughout the lower adhesive part 331 .

Here, as shown in FIG. 4, the shape retention force is not only maintaining the circular shape of the mask while wearing the mask (aesthetic aspect), but also depends on the suction force when the user breathes through the nose or mouth in the wearing state. This includes preventing (functional aspects) the mask from being crushed by the inhalation (inhalation is sucked into the nose or mouth, rendering breathing impossible).

If the shape holding force is excessive, it is advantageous in terms of functionality, but depending on the size or shape of the wearer's face, the lower adhesive part 331 does not form a straight line as shown in FIG. There is a problem of deterioration, and conversely, when the shape retention power is insufficient, there is a problem that the mask is crushed, which is of greater importance especially when using a thin fabric to increase wearability.

Accordingly, the present invention is to exhibit the optimal shape retention force even in thin fabrics through the selection of adhesive force as well as the shape of the mask (lower adhesive part, upper adhesive part, first curved part and second curved part).

The adhesive width of the lower adhesive part 331 may be provided in various ways depending on the type of adhesive, the adhesive thickness, and the application amount, but for example, a hot melt adhesive usually used for bonding fabrics has an adhesive thickness of 350 to 450 μm (about 400 μm). Adhesive width based on can be provided in the range of 5 ~ 7mm.

In the present invention, since the present invention uses an adhesive method using an adhesive such as hot melt rather than sewing as a method of fixing the end of the cutout 33, micropores that are inevitably generated during sewing are not formed.飛沫) penetration can be prevented in advance, thereby maximizing the droplet blocking function or waterproof function.

In addition, the bonding method can reduce the manufacturing cost and minimize the unit cost because the working time is relatively shorter than the sewing method and the process can be simplified to improve productivity.

The upper adhesive part 311 is provided on the extension part 31 to correspond to the lower adhesive part 331 , and has an adhesive width that gradually decreases toward the upper end from the adhesive width corresponding to the lower adhesive part 331 .

The adhesive width of the lower end of the upper adhesive part 311 may be provided in various ways, for example, as shown in FIG. 1 or 2 , the adhesive width of the lower adhesive part 331 may be the same as that of the lower adhesive part 331 . In this case, when providing one adhesive tape in which the upper adhesive part 311 and the lower adhesive part 331 are integrally formed, there is an advantage in that the manufacturing process is facilitated. Of course, the bonding width of the lower end of the upper bonding unit 311 may be provided to be wider or narrower than the bonding width of the lower bonding unit 331 if necessary, and this may be provided in response to the required shape retaining force.

The upper adhesive part 311 may be provided over the entire extension part 31 , or may be provided only in part.

For example, the upper adhesive part 311 may be provided over the entire extension part 31 as shown in FIG. 4, or a non-adhesive part (A in FIG. ), it is also possible to provide only some parts excluding the part. In this case, as shown in FIG. 4 , when the upper adhesive part 311 is provided over the entire extension part 31, the extension part 31 is lifted without being in close contact with the wearer's nose according to the shape of the nose tip of the wearer. Conversely, when the non-adhesive portion (A) is too long, the non-adhesive portion (A) may be rolled in or out by the shape retention force of the upper adhesive portion (311). Therefore, in a normal case, the non-adhesive portion (A) may be provided in a range of about 1 cm (about 0.5 to 1.5 cm).

On the other hand, as shown in FIGS. 1 and 2 , the upper bonding part 311 is provided such that the bonding width decreases from the bottom to the top. The shape (reduced width shape) of the upper bonding part 311 may be provided in various ways as needed, such as a straight shape such as a triangle, or a curved shape.

In the upper adhesive part 311, the adhesive width is provided to gradually decrease toward the top to reduce the adhesive force to maintain the shape of the upper adhesive part 311, and when the adhesive width is maintained as it is, the upper adhesive part 311 when worn It can solve problems of aesthetics or fit, such as wrinkles when pulled on both sides or lying on the left or right.

The first curved portion 333 is provided in an upwardly curved shape at the upper end of the cutout 33 corresponding to the lower end of the extended portion 31 .

Referring to FIG. 1 , the first curved part 333 is provided at the lower end of the extension part 31 , and has a substantially upwardly curved “∩” shape. Of course, it may be provided in a straight shape such as "∧", but when it is provided in a curved shape as described above, as shown in FIG. It not only forms an internal space at the tip of the nose, but also functions to prevent shape deformation of the lower adhesive part 331 and the upper adhesive part 311 around it. The first curved portion 333 may be formed at the same time when the fabric is cut.

The second curved portion 313 is provided on the upper end of the extended portion 31 and is provided in a downwardly curved shape. The second curved part 313 is closely attached to the sides of the nose bridge in the worn state shown in FIG. 4 to prevent a space from occurring between the tip of the nose and under the eyes to improve adhesion, and as shown in FIG. 3 , the gaze is focused Since it is formed in a position where it is used, it has the effect of improving the appearance.

As described above, the mask according to the present invention can maintain its shape even if it is thinner than a conventional mask due to the improvement of its characteristic shape maintaining function, thereby reducing the mask manufacturing cost, while adding various functional coatings or fabrics to the fabric Since the overall thickness of the mask is only the thickness of a conventional mask, it has the advantage of realizing multifunctionality and luxury of the mask. adsorption can be prevented.

Although the present invention has been described with reference to limited examples and drawings, the present invention is not limited thereto, and the technical idea and claims of the present invention are provided by those of ordinary skill in the art to which the present invention belongs. It goes without saying that various modifications and variations are possible within the equivalent range.
