Description of the Prior Art : In general, masks of diverse forms and structures are used to prevent the influx of harmful substances into the human body such as flower powder, yellow sand, germs, dust etc through the mouth or nose.

However, the above mentioned hitherto masks are produced in sizes and forms that neglect the external appearance. Therefore, user catches the attention of other people when wearing them. Thus, wearing of hitherto masks is shunned. Moreover, hair band, string for hanging onto the ears and bandages etc were used to connect to the masks, which caused inconvenience at the time of wearing them. Furthermore, unpurified air inflows into the gap between the surrounding areas of the masks.

Moreover, communication was made difficult at the time of wearing the mask since it covered the mouth.

This invention is the nose mask that corrected many of the above mentioned problems, and it was pre-applied for patent in the domestic locality. (Utility Model Registration Application No. 1999-0027719. Denomination of the Invention: Nose Mask with Supplementary Injection Groove).

Figure 1 is the figure that depicts the above mentioned, pre patent applied nose mask for protection against dust. As is depicted, This invention forms the exterior into 4 surfaces of right side surface (l), frontal surface (2), left surface (3) and lower surface (4) where parts are open. Distance of wall (5) is integrated with the above mentioned lower surface (4) in parallel at the inner space that is connected into the above mentioned 4 surfaces. The configuration is one that is formed with groove where N shape can be injected where filter or aromatic etc can be input.

However, the above mentioned structure of the nose mask (A) enables communication since. the mouth is exposed, and it can block the gap between the areas near the masks, but it has no function that controls elasticity. Moreover, the above mentioned has fixed structure, devoid of compatibility that enables application to diverse forms and sizes of nose. According to the size of nose, nose mask can easily separate from the nose. Wearing the above mentioned does not ensure comfort since nose mask (A) is attached closely while surrounding entire nose. Another problem is unattractive appearance.

Moreover, in case bandages etc are used to prevent the separation of nose

mask (A), adhesion function is lost easily due to humidity. Thus, the problem lies in the falling off of the nose mask (A) from the nose.
