Abstract

This invention is regarding the mask. It filters the contaminated air with automobile exhaust fumes and yellow sand during inline skating and recreation activities on the road and outdoors. As you can replace the filter only, it is very economical and environmentally friendly. It is very convenient as you can eat or communicate without taking off the mask. Additionally as it has the curved urethane sponge pad with spandex fabric inside of the body (100) which contacts the face directly, it has good contact to the face. Therefore it has enhanced comfort and absorption. As you can attach the scarf to protect from UV light and cold and it uses enforced plastic materials, it is highly safe and convenient to use.

Description

Description MASK

Technical Field

[1] This invention is about a Mask (1). It filters air contaminated with automobile exhaust and yellow sand through air filter (300) during the activities such as cycling and inline skating. It has an injection molded plastic body (100), which is molded according to the shapes of nose and mouth and a plastic frame for the mouth (200) which is movable. Therefore you can eat or communicate without taking off the mask during the outdoor activities. The air filter can be replaced.

[2] For the inner lining of the plastic mask (100) which contacts your face, it uses an urethane sponge pad (400)with spandex fabric lining (402) to give intimate contact to your face in order to enhance the air filtering, sweat absorption and the sense of comfort. Additionally, it has projections (101) and grooves (102) to fix the scarf to protect from Ultra Violet light or coldness at the outer lining of the plastic mask. Background Art

[3] Most of anti-dust masks are one-body masks where the filter and the fabric are integrated without sponge and silicon pad at the part that contacts the face intimately. As the mask does not contact to the face closely, you may breathe the contaminated air which does not go through the air filter. Even some other masks which have pads use silicon or rubber so that they do not absorb sweat and they do not give sense of comfort. Additionally, they are made in one so you should take off those masks when you want to eat or communicate. During the breathing, you may feel discomfort or the filter function may be deteriorated because of the moisture from the breathing. Disclosure of Invention Technical Problem

[4] Most of the conventional anti-dust masks are filter fabric unified mask without pad.

As the mask does not contact to the face closely, you may breathe the contaminated air which does not go through the air filter. Even some other masks which have pads use silicon or rubber so that they do not absorb sweat and they do not give sense of comfort. Additionally, they are made in one so you should take off those masks when you want to eat or communicate. During the breathing, you may feel discomfort or the filter function may be deteriorated because of the moisture from the breathing. Technical Solution

[5] To solve these problems, we project plastic body of the mask (100) according to the shapes of the nose and mouth and attach the plastic frame for the mouth (200) which is movable. The air filter (300) can be placed in or removed from the body (100) and can be replaced. You can breathe in easily through air filter (300) and out through air filter (300) and exhaust check valve sheet (202). As we use curved urethane sponge pad (400) with spandex fabric (402) at the edge of the inner lining of the body (100) which directly contacts to the face in order to increase intimacy between the face and the mask to enhance absorption and sense of comfort. It also has projections (101) and grooves (102) to fix the scarf to protect from UV light and coldness at the outer edge of the body (100).

Advantageous Effects

[6] This invention is regarding a mask. It is economical and environmentally friendly mask as you can replace the air filter only and it filters air contaminated with automobile exhaust and yellow sand through air filter during cycling and inline skating on the road and outdoors. It is very convenient as you can eat or communicate with others without taking off the mask. You can open the mouth part only. You will feel very comfortable because we use a curved urethane sponge pad with spandex fabric at the inner lining of the plastic body (100) which directly contacts to the face. It will enhance the absorption and sense of comfort when you wear it. As you can attach a scarf to the mask, you can use it to protect yourself from UV light and coldness. As the body is made of enforced plastic material, the safety and the convenience of use have been improved. Brief Description of the Drawings

Best Mode for Carrying Out the Invention

[19] We will explain this invention more concretely through the attached drawings.

[20]

[21] Drawing 1 is the skew drawing of the status of use of the invention.

[22] You can breathe clean air in through air absorption holes (103) which has air filters

(300) on the road and outdoors and exhaust the air through air filter (300) and exhaust check valve sheet (202) installed in the plastic frame for the mouth (200). [23] Drawing 2 is the skew drawing of the conventional masks.

[24] Drawing 3 is the skew drawing of the mask when plastic frame for the mouth (200) is open. [25] The mask (1) of this invention has movable plastic frame which has exhaust check valve sheet (202) so that you can eat or communicate without taking it off. You can conveniently open the plastic frame for the mouth (200) only to do that. [26] Drawing 4 is the back view of the invention.

[27] We implement the replaceable air filter (300) in the inner side of the plastic mask body (100) with air filter cover (301) through insert projection and ultra sound or heat adherence on the filter cover fixing projections (105) and implement a curved urethane sponge pad (400) with spandex fabric at the inner side of the mask which contacts to the face to enhance the contact between the face and mask and improve the sense of comfort when wearing it. [28] Drawing 5 is the skew drawing of the urethane sponge pad (400) with the spandex fabric (402) of this invention. [29] At the inner side of the plastic mask body (100) which contacts to the face, we use a curved urethane sponge pad (400) with spandex fabric (402) to enhance the absorption and sense of comfort. [30] In the urethane sponge pad (400), there will be urethane sponge pad fixing projections insertion holes (401) to attach to the urethane sponge pad fixing projections

(104) inside the plastic mask body (100). [31] Drawing 6 is the skew drawing of the mask when air filter cover (301) is attached to the air filter (300). [32] We install the replaceable air filter (300) and air filter cover (301) through insert inj ection molding or ultrasound or heat adhesion at the inner side of the plastic mask body (100) and place air filter cover fixing projections (105). [33] Drawing 7 and Drawing 8 are the front view of the mask and the scarf of this invention.

[34] We install scarf fixing projections (101) and grooves (102) to attach the scarf (500) to prevent UV lights and cold at the outer edge of the plastic mask body (100). When attaching the scarf (500) to the body (100), you can use fixing projections (101-1) or holes (102-1), or snap fasteners, or Velcro to attach the scarf (500) to the mask body (100) and remove it from the body (100).
