Description

mask {Mask}

The present invention relates to a mask that can be safely stored and reused while preventing contamination even in a situation of temporarily taking off by spreading each layer of a support member formed of a plurality of layers on both sides and folding the outer and inner parts, respectively. .

In general, a mask is a personal health device that protects the respiratory system. In particular, a mask for infection prevention has been developed in various ways to perform different functions and roles depending on the target contaminant or purpose of use. Filtering to prevent inhalation is a universal role. The worn mask is worn continuously for a certain period of time according to the purpose. Even while wearing it, if it is unavoidable such as eating or drinking, it is temporarily taken off and stored and then put on again.

In general, in a mask worn more than once, there is a possibility that respective contaminants may already be stained on the outer surface of the support member or the inner lining of the support member. Therefore, as the number of times of removing and re-wearing a mask increases, the possibility of contaminant transmission or cross-contamination increases. Therefore, a method of temporarily storing an unused mask is very important.

However, masks that have been temporarily removed have no choice but to be stored open or folded, and most of them are hung on a hanger, placed somewhere, or put in a bag or pocket, so it is not only not safe from potential contamination, but rather the spread of contamination such as cross-contamination. there is a problem.

Accordingly, things such as a foldable mask protective cover have been developed, but since it can only be used when carrying it separately from the mask, it is inconvenient to always carry the protective cover when wearing a mask, and the flat mask There is a problem that it can be used only for a specific type of mask, such as

US Patent Publication B2 No. 10660385 ‘Mask’ US Patent Publication B2 No. 10668308 ‘Filter mask having one or more malleable’ stiffening members’

An object of the present invention is to solve the problems of the prior art, and to provide an improved mask that can be used more hygienically and safely by lowering the possibility of potential contamination in the process of wearing, undressing, and storage.

The present invention mask for achieving the above object is a plurality of layers such that the outer and inner lining are spaced apart from each other; a support member having a; And the plurality of ply is an outer ply comprising an outer material, respectively; and an inner ply including a lining; and a fixing part coupled to a portion of each ply of the support member for fixing, and it is characterized in that the fixing part is capable of expanding or folding each ply about the axis.

In addition, it is characterized in that it is conveniently detachable and stored by providing a detachable part on the contact surface of each layer.

In addition, the hook portion of the mask is characterized in that it further reduces the possibility of contamination by connecting the respective layers to each other to bind and serve as a handle.

According to the mask of the present invention, each face of the mask being worn is hidden so as not to be exposed to the outside and isolates so that each face is not physically in contact by unfolding each layer of the support member formed in layers to both sides and folding the outer and inner parts, respectively. Thus, it is possible to reduce the possibility of transmission such as cross contamination when temporarily storing the mask, and by providing a detachable part on the contact surface of each layer and attaching the folded surface parts once more, the mask can be more easily installed while maintaining the object of the present invention It has the effect of being able to store it.

In addition, by connecting the respective layers to each other and using the hook serving as a handle, direct contact between each face of the mask and the hand is reduced, thereby reducing the possibility of contamination.

A normal mask is a personal health device that covers the mouth and nose. In addition, there are a cold protection mask to protect the respiratory system from the cold and a dust mask to prevent inhalation of fine dust, ultrafine dust and dust during work. also follow

Therefore, a mask is used for the purpose of preventing inhalation through the respiratory tract from an external threat, and among them, a mask worn for the purpose of preventing infection such as a pathogenic virus can be said to be an infection prevention mask.

These infection prevention masks not only filter out pathogens and contaminants in aerosols, but also prevent harmful viruses from spreading to the outside through droplets discharged by an infected person breathing, coughing, sneezing, or speaking. It also acts as a barrier.

The KF99 mask, KF94 mask, KF80 mask, KF-AD mask, dental mask (aka dental mask) and N95 mask are representative types of masks approved by the Ministry of Food and Drug Safety.

In the above name, KF is an abbreviation of Korea Filter, meaning that it was certified by the Ministry of Food and Drug Safety in Korea, and N is an abbreviation of NIOSH, meaning it was certified by the National Institute for Occupational Safety and Health.

In addition, the numbers and abbreviations used in the name refer to the grade and performance measured and evaluated by the relevant testing institution in consideration of the correlation between dust collection efficiency, facial intake resistance, and leakage rate. It means that there is an effect of collecting and filtering more than 99% and more than 94%, KF80 means that there is an effect of filtering more than 80% of fine particles of 0.6 size, and N95 means that there is an effect of filtering more than 95% of fine particles of 0.3 size means that there is And, AD is an abbreviation of Anti Droplet, meaning it is for droplet blocking.

Depending on the characteristics of the target material to be prevented, it is necessary to wear an appropriate mask to perform its role.

However, in actual use, determining whether the efficiency is high or low is somewhat different from the high and low rating criteria described above. When it is necessary to thoroughly block contamination and infection, such as for the purpose of blocking ultra-fine dust or having to come in contact with an infectious disease patient, it is most effective to use a KF94 or N95 grade mask, but suffer from uncomfortable breathing. On the other hand, it is more efficient to wear a low-grade KFAD mask than to wear a high-grade mask like KF94, which is inconvenient to breathe, in order to block substances such as droplets with larger particles than ultra-fine dust.

According to the shape, the mask can be divided into a face mask type such as a flat type or a flat type, a face mask type such as a three-dimensional type (mainly three-fold folds or three-fold fold, etc.) and a cup type, and a conventional support member (for example, a fiber Materials, fiber layers, fabrics, porous meshes, etc.) and functional elements and members (air filters, etc.) are separated or manufactured respectively by separating or combining them. , quadruple structure, etc.

The KF94 mask is composed of a total of 4 layers of outer material, intermediate material (or support member, filter, and lining), and the KF-AD mask is composed of a total of 2 layers of outer material and lining including the filter. In this way, conventional masks have several layers. It has the shape of an integrated surface by using a member of

It can be assumed that the outer and inner linings of the worn mask are already covered with various substances of very small sizes, even if they are invisible to the naked eye. As mentioned above, among these various substances, there is a possibility that microscopic substances that are concerned about infection through the respiratory tract, such as pathogenic bacteria and infectious viruses, may be included.

In addition to direct breathing, hand contact with the mask wearer is the main route of infection. Misuse and storage of a mask with a contaminated surface provides an environment that easily causes infection or cross-contamination through contact.

Medical experts point out the fact that wearers are particularly negligent about hand contact and cross-contamination that occurs when taking off and storing masks, and require careful attention from mask wearers.

The above-mentioned problems can be prevented through the structures, devices, and methods described below.

The scope of the present invention should not be construed as being limited to the embodiments described below, and various modifications may be made by those of ordinary skill in the art within the scope not departing from the technical gist of the present invention. can

It may vary depending on Accordingly, definitions of these terms should be made based on the content throughout this specification.

In addition, the same or similar reference numerals in each drawing refer to the same or similar form items or functions.

In the present invention, a plurality of plies (110a, 110b, 120a, 120b) such that the outer and inner linings are spaced apart from each other; a support member 100 having; And the plurality of ply (110a, 110b, 120a, 120b) is an outer ply (110a, 110b) comprising an outer material, respectively; and an inner ply (120a, 120b) including a lining; and a fixing part 130 in which a portion of each ply (110a, 110b, 120a, 120b) of the support member 100 is coupled for fixing; , We propose a mask, characterized in that it can be expanded or folded each of the plies (110a, 110b, 120a, 120b) with the fixing part 130 as an axis.

The mask according to the present invention, characterized in that it is safely used from contamination sources by changing its shape when worn and stored, when worn, the outer ply (110a, 110b) and the inner ply (110a, 110b) and the inner ply ( Since the contact surfaces (112a, 112b, 122a, 122b) of 120a and 120b are in close contact, there is no difference from the state of wearing a conventional mask having the integrated support member 100 .

2 is a view showing the overall appearance of the mask according to the present invention, the detailed structure and shape are as follows.

Each of the plys 110a, 110b, 120a, and 120b of the support member 100 is an outer ply 110a, 110b including an outer surface portion 111a, 111b (outer material portion of a conventional mask) and an inner surface portion 121a, 121b ) (the lining portion of the conventional mask) including the inner ply (120a, 120b) and the outer ply (110a, 110b) and the inner ply (120a, 120b) to the contact surface portions (112a, 112b, 122a, 122b) in contact with each other. divided The contact portions (112a, 112b, 122a, 122b) are outer contact portions (112a, 112b) that are one surface of the outer ply (110a, 110b) and inner contact portions (122a, 122b) that are one surface of the inner ply (120a, 120b) is divided into

Fixing unit 130 is a plurality of plies (110a, 110b, 120a, 120b) in order to fix the support member 100 consisting of a portion of each plies (110a, 110b, 120a, 120b) in the form of points, lines, or planes. It is a part that is attached and joined with

Based on the fixing portion 130, the outer gyeop (110a, 110b) and the inner gyeop (120a, 120b) and again the outer gyeop (110a, 110b) is the outer gyeop (110a, 110b) as, the inner gyeop ( 120a, 120b) is bisected once more as the inner folds (120a, 120b), respectively.

Therefore, while the conventional mask can be folded in only one direction of the outer material or the lining side, the mask according to the present invention has the outer material side, that is, the outer surface parts (111a, 111b) side, and the lining side, that is, the inner side part (121a, 121b) side. Each can be folded separately.

Figure 3 is a perspective view showing the process of folding each of the folds (110a, 110b, 120a, 120b) on both sides of the unfolding from the outer surface portion (111a, 111b) side, Figure 4 is the inner surface portion (121a, 121b) It is a perspective view shown from the side.

By folding the outer ply (110a, 110b) and the inner ply (120a, 120b), respectively, the outer surface parts (111a, 111b) and the inner surface parts (121a, 122b) are hidden and instead of the outer ply as shown in FIG. 5 according to an embodiment The contact surfaces (112a, 112b, 122a, 122b) hidden between the (110a, 110b) and the inner ply (120a, 120b) are fully exposed.

When the mask is worn, the outer surfaces (111a, 111b) are exposed to the outside and come into contact with various substances (aerosols, droplets, etc.) contained in the air, and the inner surfaces (121a, 121b) are exposed to various substances contained in the wearer's breathing or coughing. come into contact

Therefore, when the mask wearer temporarily removes the mask and wants to store it, the removed mask is divided into an outer layer (110a, 110b) and an inner layer (120a, 120b). Each layer (110a, 110b, 120a, 120b) By folding toward the outer surface portions 111a and 111b and the inner surface portions 121a and 121b, respectively, the outer surface portions 111a and 111b and the inner surface portions 121a and 121b that have already come into contact with different materials can be completely separated from each other do.

That is, since the outer surface portions 111a and 111b and the inner surface portions 121a and 121b can be stored in a state where they do not come into contact with each other, various materials that are in contact with the outer surface portions 111a and 111b and the inner surfaces 121a and 121b, respectively. prevent potential contamination, including cross-contamination with each other.

As described above, the structure and method in which the remaining parts except for the fixing part 130 can be freely folded and unfolded do not infringe on the original functional characteristics of the mask, and thus can be applied to all types of masks.

1 to 7 , the fixing unit 130 can be more easily understood.

The fixing unit 130 may be disposed singly or plurally, and may be formed in a variety of structures and methods different from one embodiment, and according to the number and shape of the fixing unit 130 , the supporting member 100 , that is, each layer The folding method or shape of (110a, 110b, 120a, 120b) may be different.

6 is a perspective view illustrating the process of folding the contact surfaces 112a, 112b, 122a, 122b once more with the second folding portion 140 as an axis in the state of FIG. 5, and FIG. 7 is the contact surface portions 112a, 112b. , 122a, 122b) is a perspective view showing a fully folded state.

As shown in FIG. 5 , in a state in which the contact surface portions 112a, 112b, 122a, 122b of the mask are fully exposed, the one side hooking part 200a and the other side hooking part 200b meet so that the one side contacting surface parts 112a, 112b, 122a, 122b ) with the second folding part 140 as the axis, the size and area are reduced when folded, providing more advantages for storage and movement.

At this time, the detachable parts 151a, 151b, 152a, 152b formed on the contact surfaces 112a, 112b, 122a, 122b are provided with a detachable member on one side of the detachable parts 151a, 151b, and the other detachable parts 152a, 152b. ) is provided with a female detachable member and attached to each other, so that the already folded mask can be stored without fear of opening or loosening.

In order to more easily detach the detachable parts (151a, 151b, 152a, 152b), the detachable member is formed with a light and simple structure and means or method as much as possible.

In one embodiment of the present invention, a velcro tape generally called a snap is used. Male tape is placed on one side of the removable parts (151a, 151b), and a female tape is placed on the other side of removable parts (152a, 152b), so that it can be conveniently detached. can

The hook 200 formed in the conventional mask is generally made of a string using a material such as nylon or nylon spandex, and is located at both ends of the mask and used to hang behind the wearer's head or ears.

The hook 200 of the mask according to the present invention connects and binds each of the layers 110a, 110b, 120a, 120b to each other and serves as a handle.

It is fixed to both end portions of the inner piezo (120a, 120b) and consists of a string passing through a hole or ring formed at both ends of the outer pup (110a, 110b).

3 to 4, the hook 200 passing through the hole of the outer ply (110a, 110b) spreads each ply (110a, 110b, 120a, 120b) to the outer surface portions (111a, 111b) and the inner surface portion (121a) , 121b) when folded toward each other comes out between the outer surface portions (111a, 111b) of the already folded outer ply (110a, 110b) as shown in FIG.

Therefore, when re-wearing, grabbing the hooks 200 on both sides exposed between the outer surfaces 111a and 111b and pulling them outward, the outer surface portions 111a and 111b and the inner surfaces 121a and 121b are spread out and each layer 110a, 110b, 120a, and 120b) are folded and the length of the hook 200 exposed toward the outer surface portions 111a and 111b becomes longer and longer, so that it can be easily worn.
