Abstract

[PROBLEMS] To prevent the exhalation of air leaking from the front face of a mask from rising, a single nonwoven fabric (hereinafter referred to as a cover) is welded and fixed to the front face of the mask on the upper side, the left side, and the right side to provide a space between the mask and the cover. In the mask that prevents the rise of exhalation by the layer of space and the glasses do not cloud, the raised shape of this cover is distorted or deformed when masking, making it difficult to breathe, and it looks worse than anything else . To provide a mask that can be adjusted to the shape of the cover cleanly or according to the mask user's preference.
A core I such as a flexible plastic, aluminum or iron plate or wire is placed in a lower side portion of a cover and fixed in a non-woven fabric bonded or folded to reinforce the lower side portion. Thereby, the space H between the mask and the cover can be freely adjusted.

Description

    The present invention relates to a mask for preventing spectacles from fogging.

    When the mask is used, the glasses become cloudy because fine water droplets are deposited on the cold eyeglass lenses due to contact with warm exhaled water containing moisture. One of the directions in which exhalation leaks is that warm exhalation coming from the front through the mask rises and contacts the lens. In order to prevent exhalation from leaking and rising from the front surface of the mask, a single nonwoven fabric (hereinafter referred to as a cover) is welded and fixed to the front surface of the mask at the upper side, the left side, and the right side. The size of the cover is the same as the upper side length of the mask, and the length of the left and right vertical sides is 70 to 90% of the mask so that it does not protrude from the mask. In addition, the lower side has a trapezoidal shape longer than the upper side length so that a space rising from the left and right vertical sides to the center by 10 to 20 mm is formed at the center. When the mask is masked, the raised shape of the cover is distorted or deformed, making it difficult to breathe. This problem can be solved if the shape of the cover is clean or can be adjusted to the user's preference.

Utility model registration No. 317670

    In order to prevent exhalation from leaking and rising from the front of the mask, there is a “mask that does not cloud the glasses” in which a nonwoven fabric (hereinafter referred to as a cover) is welded and fixed to the front of the mask. (See Patent Document 1) However, the bottom side of the cover is distorted or deformed only by the welded and fixed cover, and it becomes difficult to breathe, or the appearance is poor.

    A flexible plastic, aluminum or iron plate, a core such as a wire is placed on the lower side of the cover and fixed in a pleated nonwoven fabric bonded or folded, and the lower side is reinforced.

    The space between the mask and the cover can be adjusted freely by fixing the reinforcing core to the lower side of the cover and bending and extending the core freely. In other words, the shape of the cover can be changed according to the mask user's preference to facilitate breathing and improve the appearance.

It is a front view of the mask before welding a cover. It is a front view of the cover welded to the mask front surface. It is a front view of the mask which welded the cover to the front. It is a rear view of the mask which welded the cover to the front. It is the figure which looked at the mask which welded the cover to the front from the top. It is the figure which looked at the mask which welded the cover to the front from diagonally upward. It is image sectional drawing which looked at the mask which welded the cover to the front from the side.

It is very easy to carry out because the idea is to weld the same non-woven fabric cover on the basis of a non-woven hygiene mask that is generally available. The point is to create a space between the mask and the cover so that exhaled air does not leak out from the front of the mask, and the contrivance for this is a trapezoidal cover shape with the cover lower side length longer than the mask lower side length. With this device, it can be applied to a mask of any of a planar shape, a pleated shape and a three-dimensional shape.
This will be described below with reference to the drawings.
A shape in which the cover of FIG. 2 is welded to the front surface of the mask of FIG. 1 is “FIG. 3”.
The welded part is “E” between “A & A1” and “B & B1” in “Fig. 3”.
Between “A & A1” and “C & C1” “F”
Between “B & B1” and “C & C1” “G”
Thereby, a space like “H” in “FIG. 6” can be created.
“I” in “FIG. 6” indicates a core made of flexible plastic, aluminum, iron, or the like, and the space like “H” can be freely changed by bending and stretching. it can.

1. “A” “A1” “B” “B1” “C” “C1” “D” “D1”
“A & A1”, “B & B1”, “C & CA1”, and “D & D1” indicate the welding positions of the mask and the cover.
A is welded according to the position of A1. "A &A1"
B is welded according to the position of B1. "B &B1"
C is welded according to the position of C1. "C &CA1"
D is welded according to the position of D1. "D &D1"
2. “E”, “F”, and “G” indicate welded portions.
E indicates welding between “A & A1” and “B & B1”.
F indicates welding between “A & A1” and “C & C1”.
G indicates welding between “B & B1” and “C & C1”.
3. “H” indicates a space.
4). “I” indicates a core such as a flexible plastic, aluminum or iron plate, or wire.

Claims (1)

  A mask comprising a non-woven fabric cover having a lower side reinforced with a flexible core material welded and fixed to the front side of the mask at a side other than the lower side.
