Description

  The present invention relates to a sanitary mask that covers a nostril and a mouth of a human body, and more particularly, to a sanitary mask that can prevent fogging of spectacle lenses when worn together with spectacles.

  Conventionally, sanitary masks have been widely used for the purpose of preventing suction of foreign matters such as viruses, pollen and dust, preventing the scattering of viruses and bacteria, and preventing drying of the nasal cavity and oral cavity. Especially in recent years, sanitary masks are increasingly used in public places regardless of the season due to the increase in allergic patients and the epidemic of new influenza.

  A problem with conventional hygiene masks is that when they are worn with eyeglasses, exhaled air leaking from the hygiene mask causes the spectacle lens to become cloudy. In particular, in recent years, the number of sanitary masks that fit the user's face, such as masks using highly stretchable nonwoven fabric and three-dimensional structure masks, has been increased, and the filter performance of the mask substrate constituting the sanitary mask has been improved. Due to the increased airtightness of breath, exhalation leaks began to concentrate in the gap created by the difference between the nose and cheeks. As a result, the exhaled air in the mask flows upward along the nasal bridge toward the eyeglasses, so that the spectacle lens becomes more cloudy.

  Therefore, sanitary masks with various measures have been developed so far. For example, a wire that easily deforms is inserted in the center of the upper side of the mask that hits the user's nasal bridge, and the user enters the wire that closes the gap around the nose by bending the wire according to the shape of the nose. Sanitary masks are well known. In addition, a device that folds the upper part of the mask to close the gap around the nose, and a device in which a pad made of sponge or the like is provided at the center of the upper side of the mask have been developed.

  Furthermore, a sanitary mask that prevents fogging of glasses by providing an opening at a position near the user's nostril or mouth and releasing expiratory air from the opening is also known (for example, see Patent Document 1).

No. 7-1159

  However, with the conventional sanitary masks with wires, the gaps are often created again due to subtle deviations after wearing, and other types of sanitary masks that close the gaps around the nose also have various nasal bridge thicknesses. Due to the fineness and height, it was very difficult to completely close all the gaps. In addition, since a member for closing the gap is newly provided, the structure is complicated and the cost is increased, and as a result, there is a possibility that the disposable use is expensive.

  Furthermore, in a sanitary mask that provides an opening near the nostril and mouth, by providing an opening near the nasal cavity and oral cavity that is a path for viruses to enter the body and a discharge path for viruses and the like in the body, Sanitary mask performance may be significantly reduced.

  Accordingly, an object of the present invention is to provide a sanitary mask that can prevent fogging of a spectacle lens with a simple configuration when worn together with spectacles in view of the above-described conventional problems.

  In order to solve the above-mentioned problem, the present invention provides a sanitary mask having a mask body that covers a user's nostril and mouth, and an ear-hook portion that fixes the mask body to the user by hanging on the ear. There is provided a sanitary mask characterized by comprising one or a plurality of ventilation portions for discharging air flowing through a step portion between a user's nose and cheek at the center of the upper side of the mask body.

  Here, the ventilation part is configured by an opening. Alternatively, it is composed of an opening and a mesh material covering the opening. Or it may comprise an opening formed by incision, and the incision may be a valve that opens with exhalation and closes with inspiration.

  The plurality of ventilation portions are preferably arranged symmetrically with respect to the center line of the mask main body.

  According to the sanitary mask of the present invention, fogging of spectacle lenses can be effectively prevented even when worn with spectacles with a very simple configuration. This effect can be exhibited regardless of the deviation after wearing or the thickness or height of the user's nasal bridge. In addition, since the configuration is simple and the cost can be kept low, it can be used in a disposable manner. In addition, by providing a ventilation part in the center of the upper side of the mask body, not in the vicinity of the user's nostril or mouth, that is, in the vicinity of the step between the nose and cheek, it prevents fogging of the spectacle lens while maintaining the function as a sanitary mask. can do.
