Description

Mask comprising pocket unit}

The present invention relates to a mask including a pocket portion. Specifically, it relates to a mask including a conventional mask and a pocket portion that improves the airtightness of the area around the nose.

Masks have been used limitedly as products related to disease. It was used as an auxiliary means to prevent spreading one's disease to others or to prevent infection from others. Due to the influence of yellow dust and fine dust, the number of people wearing masks has increased, but this is also to prevent diseases.

Due to the COVID-19 (coronavirus infection-19) pandemic, awareness of masks has changed rapidly. Masks were treated so precious that they were in short supply, and it was socially learned that masks alone were highly effective in preventing disease. The experience of living with a mask on for most of the day was also widely shared. Negative views about covering one's face by wearing a mask have also eased regardless of whether it is Eastern or Western.

Masks have become a daily necessity like glasses. All households are always stockpiling the minimum quantity. Wearing a mask has become very natural, even when it comes to pollen in spring, yellow dust, car fumes in the middle of summer, and even a mild cold in winter. Just as wearing glasses is not strange at all, wearing masks has also become a very natural part of our culture.

As the temporal, spatial, and cultural environment for masks has changed rapidly, a new concept of mask that transcends the current concept is needed. Conventional masks are manufactured with only the functionality of temporary wear in abnormal cases in mind, so a new type of mask that can be worn not only on a regular basis but also for a long time and that takes into account the user's fashion is needed.

The problem of the device not fitting properly on the face and lifting up is a common problem found in masks, goggles, gas masks, VR headsets, etc. The surrounding area, including the nose, is more curved than other parts of the face, the skin is thin, so there is little cushioning, and the height is high, making it difficult to fit accurately with the face. Additionally, this is an area that leaks more easily as facial muscles move when breathing or speaking.

In order to solve the above problem, deformable elastic material was inserted into the peripheral area, including the nose, of the mask or attached to the surface, but it still does not adhere accurately to the face. In most masks, metal such as wire is modified so that even if the mask is briefly attached to the face, there are no supporting parts, so gaps easily form due to the movement of facial muscles. This problem is very simple and appears to have already been solved, but in reality, it remains unfinished and unresolved for a long time.

Movement of facial muscles due to conversation, etc. causes movement of the mask. When a mask must be worn for a long time, such as with COVID-19, skin damage occurs due to friction between the bridge of the nose and the mask. Nurses and other medical staff attach a band or bandage to the bridge of the nose and wear a mask over it to prevent skin damage caused by frequent friction.

Gas masks can increase adhesion to the face by applying elastic sealing parts such as silicone to the band mounted behind the head to compress the surrounding area, including the nose. In this case, the force pressing the surrounding area, including the nose, is relatively large, making it difficult to operate for a long time. In addition, the problem that women avoid because marks remain on their faces is also a problem that needs to be solved.

Masks and gas masks are devices that block air flow, but VR headsets require both air flow and light blocking at the same time. When wearing a VR headset, if the surrounding area, including the nose, is not sealed, problems with reduced concentration due to light exposure occur. All currently released products do not seriously consider this problem and instead present unfinished technologies that apply strong pressure, such as gas masks, as a solution.

Patent Document 1 relates to a mask aimed at eliminating respiratory leakage, selecting a filter part with optimal pores, relieving suffocation, and also providing a function to prevent glasses from spilling. It consists of a fixing frame part that has good adhesion to the skin contact area, a filter part that can be freely separated and attached, and an attachment part to be fixed to the face. Each part is made of different materials and functions are divided. Notches are placed on the skin-contacting parts of the fixing frame to expand the contact area by the tension of the mounting part, and shape memory resin or skin-adhesive resin that shrinks at the temperature of the skin is used as the material. The upper part of the contact part uses an elastic resin that expands and contracts in response to facial muscle and skeletal deformation due to changes in conversation or facial expression. The filter part can be separated from the fixing frame part, and a mask is provided in which the necessary material can be selected depending on the purpose.

Patent Document 2 relates to a mask including a nose-sealing portion, and provides a mask having an improved nose-sealing portion that covers at least one of the user's nose and mouth because it supplies breathing gas under positive pressure, and includes a first paddle. and a second paddle.

Patent Document 3 relates to a mask with a nose pad attached, and is composed of a mask body, a nose pad, and an inner layer wrinkle. The mask body has an outer layer surface, a middle layer surface, and an inner layer surface, the nose pad is disposed on the outer layer surface, and the inner layer The wrinkles are formed by extending and folding from the inner layer surface, and the inner layer wrinkles and the outer layer surface simultaneously cover the nose pad, providing a mask in which protrusions corresponding to the nose pad are formed on the mask body.

Patent Document 4 relates to a close-fitting mask equipped with an elastic band, and a secondary close-fitting portion with elasticity and flexibility is formed along the edge of the mask body, and the upper inner part of the mask body is tightly attached by wrapping the bridge of the user's nose from above. A nose pad is provided, and a side lower membrane is formed in a closed curve shape downward from both sides of the nose pad and surrounds the nose and mouth, and the edge of the side lower membrane is made of an elastic and elastic material for close contact with the skin. It is characterized by forming a close contact part and providing a separate elastic band with elasticity at the upper position as one side of the secondary close contact part to increase the adhesion of the nose pad 40 to the bridge of the nose and prevent upward outflow of internal air. .

Patent Document 5 relates to a mask, and the center of the inner upper part of the cover is provided with a receiving groove for receiving the bridge of the nose, and the skin is inserted into the space formed between the bridge of the nose and both cheekbones under the eyes of the face on both sides of the receiving groove. A mask provided with a sealing means provided with a protrusion that is in close contact with the mask is provided.

Patent Document 6 relates to a mask that can prevent gas from flowing into the inside of the mask without being filtered by the filter sheet, and provides a mask including a nose clip and/or nose pad.

Patent Document 7 relates to a dust mask that prevents fine dust from entering the respiratory tract. It has an upper cover with a nose support formed on the inner side at the top and bottom, and a lower cover with a chin support with an air discharge part formed so that the user can wear the mask. Provides a mask that can be easily worn with the nose support formed on the upper cover in close contact with the nose without any additional manipulation when worn.

Patent Document 8 relates to an eco-friendly traditional Korean paper mask, which includes a mask body 100 that is formed to fit the curvature of the face to shield the mouth and nose, and a fixing strap formed on both sides of the mask body 100 so that it can be hung on the ears. It enjoys the unique functions of Hanji, including (200), and effectively absorbs and filters fine dust, pollutants, and various harmful bacteria, while maintaining a comfortable condition for a long time due to its excellent breathability, thermal insulation, quick drying, and antibacterial properties. It is especially harmful to the human body. We provide eco-friendly masks that can be safely used by children and the elderly.

In this way, Patent Documents 1 to 8 disclose various means for close contact between the mask and the surrounding area, including the nose.

The conventional technology is that 1) the degree of adhesion is weak even if it is temporarily adhered when worn, and 2) since it is an area of the face where the user's muscles have no choice but to move, not only is the adhesion easily weakened by the movement of the facial muscles, but also the skin such as the bridge of the nose is affected. Skin damage occurs due to frequent friction with the face, 3) if the user moves while wearing a mask or VR headset even without facial muscle movement, the degree of adhesion is weakened due to vibration, and 4) the contact area is like a nose pad, It provides a form of strong pressure to the area, which causes female users to avoid wearing it because their makeup is removed. 5) In the case of some gas masks, the degree of pressure cannot be adjusted, so only strong pressure is possible, and 6) the user's Since the degree of adhesion varies depending on the level of skill, users who are not familiar with controlling the device or equipment, such as the elderly or children, may achieve incomplete adhesion. 7) If a face shield is added, it is still double-fixed to the face. There is a problem that needs to be addressed.
