It relates to a mask provided with.

In modern cities, everyday life is led by changes in the natural environment such as climate change, desertification, yellow dust, and exposure to air polluted by artificially produced fine dust such as automobile smoke and factory smoke. In particular, the bronchus is directly exposed to fine dust due to respiration, and thus, the occurrence of respiratory diseases such as cough, asthma and bronchitis is increasing. As the harmful substances in the air increase, the number of deaths from respiratory diseases is gradually increasing. In particular, Seoul has higher dust concentration than other large cities due to the effects of fine dust and yellow dust.

According to information released by the Ministry of Environment Air Quality Annual Report 2013, as in many big cities in the fine dust concentration in Seoul 45μg / m ³ of about 1.5 times the level of about three times in London ^{18μg / m 3, LA 30μg /} m 3 You can see the high. Therefore, it is necessary to protect the bronchus from fine dust and various harmful substances, and many people wear a mask when going out for this purpose.

Conventional general health masks or dust masks have been invented to prevent inhalation of airborne dust and fine dust, and have a much higher rate of blocking fine dust than normal masks and can be shaped to fit the surface of the face. It comprises a metal implant. In addition, by including a filter for blocking harmful substances inside the mask can block the fine dust or other harmful substances contained in the outside air.

Conventional masks, however, are often in the form of soft, linear aluminum strips where the contact with the nose is malleable, which fits snugly over the wearer's nose, but can often lead to discomfort by putting tight pressure on the wearer's nose and cheekbones. have. Therefore, there was a difficulty in using a mask when you feel a foreign body when worn for a long time.

Much research has been conducted to solve the above-mentioned problem, and in particular, Japanese Patent Laid-Open No. 2005-035148 discloses a nose mask formed of a resin material having shape retention characteristics, and a face mask including a nose clip. The shape retaining material is formed of an oriented polyolefin-based resin having a rolling ratio of 5 to 16 times, a draw ratio of 1.3 to 2.5 times, and a total draw ratio of 10 to 40 times.

However, the nose clips added to these masks not only have the ability to deform, including bending and twisting, to accommodate a wide variety of nose shapes of the wearer, but also the ability to retain the shape so that the deformed shape is maintained at least against its own weight and self-resilience. It does not include the technical features with. In addition, it is embedded in the mask may degrade the function of the mask several times. Therefore, there is a demand for development of a COClip technology that can compensate for the problems of the COClips embedded in such masks and thus do not feel foreign objects even when used for a long time.

Since the airgel of the present invention is mass-produced through a sol-gel process, various materials such as TiO2 (Titanium Dioxide) and Aluminum can be applied, and are classified into ceramic silica airgel and polymer carbon airgel. Aerogels can be applied to all industrial fields requiring insulation and low dielectric properties, and the most popular field is the transparent insulation material market. Silica airgel has 100 times the insulation and visible light transmittance of glass windows, so it transmits light but does not transmit heat, thus replacing the glass market for construction. In fact, the application of transparent granular aerogels to building exterior wall insulation in Ardon, Switzerland, is reported to have reduced the average annual oil use to 1/10. However, silica airgel has been recognized for its applicability as a coating material because it is difficult to improve strength. It is considered to be very useful as an insulating coating material for semiconductor Low-K by applying super insulation. In addition, silica aerogels are expected to greatly improve thermal insulation by coating on double glazing glass, and to replace PU foam in refrigerators and freezers, and contribute to the efficiency of air conditioning systems.

The nose band 20 of the present invention can produce a transparent nose band by surface-treating the aerogel on the polymer resin, it is excellent in heat insulation and can effectively use a mask having a nose band warm even in winter.

Traditional hydrogels have limited mechanical properties and are limited in their application, but are complemented by the addition of reversible crosslinks to hydrogels.

In particular, recently developed dual network hydrogels have been developed to reinforce mechanical properties by simultaneously incorporating physical crosslinking and chemical crosslinking into hydrogels. The hydrogel of the present invention is preferably used to increase the adhesiveness by coating the polymer resin, it may be effective to use the nose band in close contact with the nose.

The nose band 20 of the present invention can increase the adhesiveness by including the adhesive layer 22 can further enhance the adhesion and seating of the nose 5 and the nose band 20, accordingly the mask 10 It can be used in close contact. Therefore, it is possible to prevent the fine dust from being introduced into the mask and to prevent the oxygen from being discharged to the outside of the mask.

In addition, the adhesive layer 22 of the present invention may be provided with a plurality of layers, and may further include a support film provided between the adhesive layers to separate the adhesive layers. Although not shown in the drawings, the plurality of layers is preferably composed of two or three layers, and by including a support film between the laminated pressure-sensitive adhesive layer can be removed by removing the support film peel off the adhesive layer. Therefore, when the user uses the mask several times, the nose band 20 in which the adhesive force is deteriorated by hand is peeled off by the support film to expose a new adhesive layer, even when using the mask 10 including the nose band 20 several times. Adhesion can be maintained.

In addition, although not shown in the drawings, the adhesive layer which increases the adhesiveness according to the outer peripheral surface of the mask in contact with the skin may be surface treated. In addition to the nose band, by providing an adhesive layer on the mask can further increase the adhesion of the skin and can reduce the leakage rate of the upper, lower and side of the mask when the oxygen generated inside the mask.

In addition, the adhesive layer 22 may include 0.1 mm to 3 mm, preferably 1 mm to 2 mm. If the pressure-sensitive adhesive layer 22 is less than 0.1mm, it is difficult to sufficiently increase the adhesiveness of the nose band 20, and if the pressure-sensitive adhesive layer 22 exceeds 3mm, it is difficult to significantly increase the adhesiveness compared to the coating amount.

8 is a view schematically showing an example of a nose band including a punching hole according to an embodiment of the present invention.

As shown in FIG. 8, the nose band 20 may further include a punching hole 20 ′. In particular, when using the nose band 20 for a long time in the summer, sweat can flow from the skin in close contact with the nose band 20, users with sensitive skin may cause skin problems on the contact area. Therefore, the nose band 20 is provided with a plurality of punching holes 20 ′, and the mask 10 may be effectively used for a long time by maintaining the adhesion and allowing the air to move. In addition, the nose band 20 of the present invention can be used in a detachable manner, can be reused many times by washing in water.
