[Technical field]

[0001] Switching from disposable masks to reusable masks will help conserve resources and be more environmentally friendly. Attached to the entire front of the frame The aim is to improve hygiene and the environment by providing protection against saliva and droplets caused by coughing and sneezing through the attached resin film of the first mask, suppressing contamination of the antibacterial material of the internal second mask, preventing emissions from the wearer, and simplifying disinfection by separating the mask. [Background technology]

[0002] Disposable masks are simple, inexpensive hygiene products that provide protection against viruses, bacteria, pathogenic microorganisms, pollen, dust, and fine particles, and are attracting worldwide attention as they have a significant impact on life, hygiene, and health.

[0003] Wear it to protect against viruses, bacteria, dust, etc. Disposable masks For hygienic reasons, disposable masks are mainstream and are discarded after a single use. However, in the event of an epidemic, huge quantities are consumed, which results in large amounts of waste, which can lead to environmental degradation and marine pollution.

[0004] Disposable mask The structure is simple, mass production is possible, and the unit price is low, but since they tend to be used frequently and for long periods of time as a disease prevention measure against viruses and bacteria and due to environmental pollution such as hay fever and fine dust, they require a more advanced antibacterial and dustproof structure, improved usability, and measures to address environmental issues. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication 2019-049083 [Patent Document 2] Answer: 3225473 [Patent Document 3] Problems that Patent 6462793 Invention aims to solve

[0006] Disposable masks are widely used around the world, but the risk of pathogenic diseases such as viruses and bacteria, and environmental pollution particles such as PM2.5, are international issues, and the huge consumption of masks due to their long-term use by most of the world's population results in huge costs and a waste of resources as waste.

[0007] Disposable masks are generally used as a medical defense measure against viruses, bacteria, and pathogenic microorganisms, and as a defense measure in the living environment against hay fever, dust, and environmental particles. They are inexpensive and easy to use, but there are issues with their effectiveness in preventing viruses, bacteria, and pathogens, and with how to use them.

[0008] Disposable masks have a one-piece structure, with laminated sheets of hygienic materials such as gauze, nonwoven fabric, and cloth that protect the mouth and nose being attached directly to a frame. Issues with disposable masks include contamination from large droplets from coughs and sneezes sticking to the front of the fabric, penetration of fine droplets into the mask, and the passage of aerosolized viruses.

[0009] The antibacterial and dustproof material of disposable masks is a laminated set, and if the laminated fabric becomes contaminated, the entire mask will have to be discarded, which will generate waste along with the synthetic resin and chemical fibers that make up the frame, causing environmental and marine pollution.

[0010] Disposable masks and sanitary material sheets are of standard performance, so adding sanitary material directly to increase the defense against viruses, bacteria, etc., creates issues with the fit, as it feels uncomfortable on the skin and makes breathing difficult.

[0011] Disposable mask The ear loops are standardized according to individual differences such as face shape, gender, and child. If they are too short, ear pain may occur when wearing them for long periods of time. It's a pain to use, If the wire is too long, it can become loose or slip, making it difficult to use.

[0012] There are reusable masks with synthetic resin fabric frames, but because they are a one-piece structure, they can be washed before reuse. It is necessary, Issues include the deterioration of the antibacterial effect due to the used feel after washing and the misalignment and unevenness of the fiber weave.

[0013] Disposable masks usually need to be replaced at least once a day due to hygiene and health concerns, pathogens, and poor sanitary conditions. With the frequent occurrence of new pathogens and natural disasters, masks are worn for long periods of time, so there is a need to improve the fit and decorativeness of masks to reduce waste and reuse them.

[0014] The top edge of the reusable mask is It is located between the eyes and nose, the bottom edge fully covers the chin, and the left and right edges cover most of the cheeks, so it is flexible and stretchy all around. Resin strip frame Made of thin, strong and A flexible resin film is attached to the front surface of the resin strip frame. This will be the first mask.

[0015] Reusable masks have a resin film attached to the entire surface of the resin strip frame. Small holes are made around the mouth, nose, and cheeks to allow air in and out. Although incomplete The first mask is secured and used as the first mask, and a laminated sheet of antibacterial hygienic material such as gauze, nonwoven fabric, or cloth is placed inside the gauze bag to be used as the second mask. A resin strip is inserted from left to right on the inside of the upper part of the mask frame. Fix one side, The laminated sheet The mask is attached and detached by a clip between the resin film and a hook or belt fastener on the other side, and the lower part of the mask has the same structure.

[0016] Reusable masks The resin around the Band plate frame The parts are interconnected to maintain mobility, and the elasticity adjusts to fit the individual changes in the face. High, nose On the center line of the mouth The resin strip of Installed at the top and bottom It expands and widens the space between the nose and mouth to ensure easy breathing, and prevents the uncomfortable fit that can result in breathing difficulties and contamination by saliva and nasal mucus due to gauze or fabric coming into contact with the nose and mouth when inhaling.

[0017] Reusable masks The resin membrane has many small holes evenly spaced from the nose to the chin to allow for breathing. ensure, The resin membrane captures large droplets and small particles that are generated when coughing, sneezing, etc. First Mask It minimizes contamination and penetration of sanitary materials such as inner gauze, nonwoven fabric, and cloth.

[0018] The mask's blocking rate is determined by the ratio of the above-mentioned small hole area to the membrane area, and it prevents the penetration of large droplets, small droplets, and fine particles into the membrane, viruses, bacteria, and other aerosol particles, as well as airborne viruses. It prevents contamination of sanitary materials and maintains antibacterial properties. Greatly inhibits internal penetration and passage.

[0019] Reusable masks are separated into a first mask made of a resin membrane and a second mask made of hygienic material on the inside. After use, the first mask can be disinfected with a disinfectant spray or immersion, and can be reused immediately after disinfection by wiping with a disinfectant cloth. The hygienic material of the second inner mask can also be disinfected by immersion or replaced with a new material for reuse.

[0020] Inside the first mask The upper and lower parts are fitted with a resin strip that runs from left to right. Gauze, nonwoven fabric, cloth, tissue paper, and other hygienic material sheets with antibacterial and dust-proof properties are folded and inserted into bags, and combined into a layered set. The upper and lower two parts inside the mask Resin strips to clip sanitary materials In addition, a hook and eye fastener is fastened at one end to increase protection.

[0021] Second mask laminated material sheets and sets With resin strips Clip it on and fold it over the band plate to make it double, expanding the space between the mouth / nose and the seat surface to allow air to be circulated. It becomes comfortable and comfortable to wear. Improve.

[0022] Ear holes at the four corners of the first mask Equipped The ear loops can be used as holes for decorative strings such as strings, belt strings, braided strings, or elastic strings, and the length of the ear loops can be adjusted to the strength preferred by the user depending on the size of the head and face, gender, and age difference, eliminating the slippage and slackness of the mask and providing a comfortable fit.

[0023] First mask The entire frame is covered with resin This provides frontal protection and the inside of the mask. Antibacterial properties of the hygienic material Due to the division of roles, the shape of the mask changes with the front, causing pressure and breathing difficulties. Installation by Improve dislike. Effects of the invention

[0024] Globally, special viruses and pathogens are spreading across all continents, and the importance of wearing masks has become widely recognized. There is a huge global demand for masks, which helps prevent waste of resources and money and environmental degradation caused by disposable masks.

[0025] The resin membrane of the first mask prevents and significantly reduces the self-emission from the inside of the mask due to coughing, sneezing, and droplets, as well as the scattering and intrusion of droplets, fine particles, viruses, bacterial aerosols, etc. from external carriers. Mask sterilization performance Improving this increases the defensive effect.

[0026] The resin membrane of the first mask reduces external droplets and fine droplets from coughing, sneezing, etc., while the gauze, nonwoven fabric or cloth of the second mask can be soaked in disinfectant and then dried to make the inside antibacterial and dustproof gauze, nonwoven fabric and other hygienic materials, as well as tissue paper, paper towels and other readily available materials, expanding the range of options and enabling reuse in a short time.

[0027] Antibacterial and dustproof second mask The sanitary material is folded and laminated, and the upper and lower clips are Resin strip Adjust the width of the sheet so that the top and bottom overlap slightly and clip together at the top and bottom, then fasten and secure with hooks and fasteners to prevent the material from shifting or becoming distorted.

[0028] With the conventional method of reusing masks after washing, the antibacterial performance against the penetration and infiltration of viruses and bacteria is reduced due to clogged fibers or uneven fiber weave, and there is a feeling of wear and fatigue after washing, or the washing and drying take time, so reused masks are highly convenient in terms of cost-effectiveness.

[0029] The resin frame and resin film of the front mask are made from naturally degradable resin derived from organic matter, and the hygienic material of the second mask is layered with cellulose fiber, nonwoven fabric, cloth, and paper products to form a sheet or sheet set; the entire mask is made from natural materials, making it easy to separate when discarding.

[0030] As the world becomes more integrated through economy, information and travel, protection against pathogenic diseases such as viruses and bacteria, and environmental pollution such as fine dust and dust particles typified by hay fever and PM2.5 have come to the forefront of international attention. Disposable masks have become widespread worldwide, and as a result, environmental pollution problems caused by mass consumption due to daily replacement and disposal after use, and mass disposal caused by wearing masks for long periods of time and long-term use have been addressed. Reusable maskcan be solved. [Brief description of the drawings]
