JP 2005-137858 A JP 2007-68892 A

Here, the inventor has already developed a mask cover for solving such sanitary problems (Patent Document 1 and Patent Document 2).
Each of the mask covers described in any of the documents is composed of a flat sheet covering the mask body, and the vent hole is provided in the sheet in order to reduce the burden on breathing. In this case, the sheet is in contact with the surface of the mask body, and it is difficult for the user to breathe.

  Accordingly, an object of the present invention is to provide a mask cover having a high sterilization / dust removal function without a burden during breathing.

  The mask cover of the present invention covers the entire surface of the mask body and shields the mask body from the outside, that is, from viruses, bacteria, dust, impacts, and the like. The nose opening covering portion covering the mask body from the left end portion to the right end portion is made of a single sheet material, and in the sheet material, the horizontally long belt-like portion at the center thereof is raised in a horizontally long mountain shape. When the mask cover is overlaid on the surface of the mask main body, a pair of ventilation holes are formed between the left and right ends of the band-shaped portion and the surface of the mask main body at the left and right ends of the chevron. It is characterized by.

  With such a configuration, a cavity is formed between the surface of the mask body and the sheet material at the position where the sheet material is raised in a chevron shape with the mask cover attached to the mask body. Since the vents communicate with the outside air at both ends, the burden when the user breathes is about the same as when the mask cover is not used even if the sheet material is not provided with a notch for ventilation. To be reduced.

The mask cover of the present invention has a mask body that has a vertical and horizontal width substantially equal to or greater than the vertical and horizontal width of the mask body on which the mask cover is mounted. A covering shape is preferable.
The nose mouth covering part may partially cover the central part of the mask main body as long as it covers from the left end to the right end of the mask to which the mask cover is attached. The mask cover may be configured to cover the whole. The mask cover of the present invention is characterized in that it is not necessary to provide a cutout for ventilation in the nose mouth cover part from the viewpoint of ensuring high sterilization / dust removal and the like. You may provide the notch concerning a mouth covering part.
The nose mouth covering part also has a desired additional function such as a holding part for securely attaching the nose mouth covering part to the mask body and an eye covering part for providing an eye protection function. An appropriate configuration may be added.

The mask cover can be attached to the mask body using an appropriate coupling means such as a staple. Moreover, especially when the nose mouth covering part has the holding part, it can be appropriately attached to the mask by the holding part.
In the mask cover, at least the nostril covering portion is made of a sheet material, but the mask cover may be made entirely of a sheet material. As such a sheet material, for example, paper or non-woven fabric can be used. However, the sheet material is not limited to these, and any paper-like material that can hold the horizontally long chevron shape itself and is airtight can be used as appropriate. As such a sheet material, a material having higher airtightness is suitable so that viruses, bacteria, and the like can be surely blocked. For example, a plastic sheet can also be used appropriately.

  The mask cover of the present invention allows the user to breathe comfortably with the mask cover attached to the mask body without providing a cutout for ventilation in the sheet material. According to the present invention, it is possible to provide a mask cover having an extremely high shielding effect from the outside.

The present invention will be specifically described by the following examples. The following examples are merely examples and do not limit the present invention.
