Description

TECHNICAL FIELD The present invention relates to a mask frame that is attached to the face side of a sanitary mask and is a means for enhancing breathability at the nostril, and more particularly to a mask frame that is gentle on the face and is not affected by the size of the sanitary mask. .

In general, masks typified by sanitary masks are used for anti-dust, anti-gas, anti-pollen, anti-bacterial, etc., as well as anti-virus, which is the cause of infectious diseases. Masks made of cloth or non-woven fabric can easily purify the air and provide the mask wearer with an environment that facilitates breathing and conversation. In the description of the present invention, not a mask that requires specialized and advanced functions such as a gas mask, but a general sanitary mask made of cloth or non-woven fabric as described above. ” shall be referred to as

However, when wearing a normal mask for a long time, it becomes difficult to breathe due to tight contact, and not only discomfort but also traces remain on the nose, cheeks, and chin of the face, and in some cases, rough skin. There is also For women, the mask may strip makeup or remove lipstick. In addition, an allergic person may develop an allergy due to the cloth or non-woven fabric that is the material of the mask.

In addition, recent masks with a nose wire have a soft wire or other material that can be easily bent on the top of the mask. be able to. However, this too does not fit well on the nose, and often exposes the nose to the outside when the mask is worn. Naturally, the exposure of the nose eliminates the antibacterial and antiviral function of nasal breathing.

In order to solve the above problems, various proposals have been made based on various studies in recent years, such as the prior art documents listed below.

For example, Patent Document 1 discloses a mask pad that is used by being attached to the inside of a mask. A face-facing side air intake/exhaust part made of a filter material having a specific property and attached to the periphery of the pad body, and a mask side air intake/exhaust part consisting of a hole provided at a position facing the mouth when the pad body is worn on the face. A technical idea related to a mask pad characterized by having the following is disclosed.

However, in this example, since the mask pad is large and covers the entire mouth, it is heavy and very troublesome when worn. Moreover, it can be imagined that the air penetration part is narrow and stuffy. In addition, since the mask pad is in the form of a mask that covers the mouth and nose, it cannot be said to be sanitary if it is repeatedly used. And it is hard to say that it can be easily used by general people.

Further, in Patent Document 2, a mask is provided in which attachment straps are arranged on both sides of a substantially rectangular mask body, and the mask body is bulged to form a space in front of the user's mouth. The shape-retaining means for securing the space includes both end portions fixed to both side edge portions inside the mask body, and a bridging portion elastically curving between the both end portions. and a support member for receiving the mask body from the inside, and fixing means for fixing at least the both end portions of the support member to the inside of the mask body. A technical idea is disclosed.

However, even in this example, the bridging part only lifts the mouth part of the mask to form a space around the mouth. Do not go beyond the already mentioned mask with nose wire. Furthermore, it is self-evident that misalignment during wearing of the mask causes problems such as the nose being exposed to the outside and the chin being disengaged.

The present invention intends to solve these problems in the conventional technology, and provides a sanitary mask that can be easily used by anyone, reduces the suffocation of breathing caused by wearing it for a long time, and improves adhesion to the facial skin. To develop and provide a mask frame capable of reducing rough skin and allergies by alleviating them, preventing makeup and lipstick from peeling off, and avoiding exposure of the nose and chin due to slippage of the mask. is the subject.

In addition, it can be commonly applied to cloth or non-woven masks of different sizes, and it is possible to dramatically improve the safety and workability of wearing the mask while greatly improving the economic efficiency such as manufacturing costs. It is an object of the present invention to provide a possible mask frame.

In order to solve such problems, the mask frame according to the present invention is
an upper holder portion having one or more first mask holding claw portions that fit and fix the upper side portion of the mask;
a lower holder portion having at least one second mask holding claw portion that fits and fixes the lower side portion of the mask;
A mask frame comprising a mask frame main body portion in which the upper holder portion and the lower holder portion are integrally or integrally connected,
The mask frame main body portion is a joined body for fitting and connecting the upper main body portion and the lower main body portion, wherein the fitting connection portion has a lock claw portion on the upper main body portion, and the lower main body portion has a lock claw portion. The mask frame has a plurality of locking openings arranged in a vertical direction for engaging the locking claws, and the mask frame is formed by selecting a fitting position between the locking claws and the locking openings and connecting them. It is possible to change and adjust the overall vertical length to fit regardless of the vertical size of the mask.
is characterized by
and,
When wearing the mask, forming a space between the mask and the mask and around the nostrils and mouth of the person,
In addition, it is characterized by forming a concave curved surface structure for bringing the mask into close contact with the skin in the vicinity of the nose and the vicinity of the lower jaw.

In other words, the mask frame according to the present invention is attached to the face, which is the back side of a mask such as a sanitary mask, and when a person wears the mask with the mask frame according to the present invention, the mask frame is worn from the top of the nose to the lower chin. is properly covered with a mask, and by forming a space between the mask and the face in the vicinity of the nostrils and mouth, it is possible to breathe and talk without stuffiness. .

In addition, the mask frame according to the present invention is a mask frame that extends from the vicinity of the tip of the nose to the vicinity of the center of the cheek to the lower chin. The mask can be softly adhered to the skin in the vicinity of the nose and the vicinity of the lower jaw. (See FIGS. 1, 2, 6, and 7. However, the present invention does not limit the outer shape of the mask frame to that shown in FIGS. 1, 2, 6, and 7. The essence of the present invention is , the technical idea of the mask frame that allows the selection of shapes that embody the functions of the above parts.)

The mask frame according to the present invention has an upper holder part, a lower holder part, and a mask frame body part, but these parts may be separate members or may be an integrated mask frame. It may also be a mask frame having a structure in which the whole is divided into two. In the description of the present invention, in order to explain the function of each part of the upper holder part, the lower holder part, and the mask frame body part in detail, they may be described as separate members for convenience.

In addition, the number of the upper holder part, the lower holder part, and the first mask holding claw part and the second mask holding claw part associated therewith should be one or more, and the present invention does not limit the number. do not have. As will be described later, it has a structure that can be easily attached to a mask worn by a person and can be easily removed, and can be used repeatedly.

The mask frame main body portion and/or the upper holder portion and/or the lower holder portion of the mask frame according to the present invention are made of a flexible and/or bendable material, and the upper holder portion holds the mask. The lower holder part is an L-shaped structure that covers the vicinity of the person's lower chin from above and below when the mask is worn. Due to this, it is possible to adopt a form that is softly and tightly bonded to the human face.

Since the mask frame main body, the upper holder, and the lower holder are made of flexible and bendable materials, they come into close and gentle contact with the human facial skin and do not cause discomfort. Materials having flexibility and bendability are preferably synthetic resin elastomers, silicone resins, or soft synthetic resins such as silicone rubber, urethane rubber, and neoprene rubber, but may also be natural rubber or soft metals. does not limit the soft material.

Again, the upper holder part and the lower holder part may be made of synthetic resin elastomer, silicon rubber, natural rubber, soft synthetic resin material such as urethane rubber or neoprene rubber, or other soft material. can. Since the upper holder and the lower holder are parts that come into contact with human skin, it goes without saying that they may be made of particularly soft materials and may be given functions such as anti-allergic properties. In the present invention, a soft synthetic resin having flexibility and bendability is referred to, but general thermoplastic resins or thermosetting resins used in injection molding processes also have flexibility and bendability. It is claimed that any material can be applied and is included in the technical idea of the present invention.

In addition, more specifically, the mask frame main body of the mask frame according to the present invention is a joined body for fitting and connecting an upper main body and a lower main body, wherein the upper main body and the lower main body are joined together. It is also possible to adopt a mode in which the length of the entire mask frame in the vertical direction is variable by providing a plurality of selectable fitting connection portions of the mask frame in the vertical direction.

In addition, since the upper holder part of the mask frame according to the present invention is a concave curved surface structure that covers the vicinity of the nose bone of a person from the left and right when the mask is worn, The concave curved surface structure of the upper holder part is applied to the slanted part of the mask, and both sides of the structure are formed deep enough to come into contact with both cheeks of a person, so that the mask can be worn without a gap on the sides of the nose. This is because the upper part of the mask fixed to the upper holder part is in close contact with the skin on the side of the nose in line with the shape of the upper holder part.

When the mask is worn, gaps on both sides of the nose facilitate the infiltration or diffusion of dust, viruses, etc. by respiration. The mask frame according to the present invention can protect against this by the structure of the upper holder portion. In addition, the mask frame according to the present invention eliminates the gaps on both sides of the nose for westerners with very high noses and allows them to wear the mask in close contact with the skin. It is also possible to prevent so-called wearing of a mask with a nose protruding.

The fitting connecting portion of the mask frame according to the present invention has a lock claw portion in the upper body portion, and a plurality of locking openings arranged in the vertical direction for fitting the lock claw portion in the lower body portion. The length of the entire mask frame in the vertical direction can be changed and adjusted by arbitrarily selecting the fitting position between the lock claw portion and the latching opening portion and fitting and connecting the lock claw portion and the latching opening portion. It can also take a form that can be adapted regardless of its size (see FIGS. 6, 7 and 8).

In other words, the masks used by people have various sizes, and the length in the vertical direction varies greatly depending on the difference between the mask for children, the mask for women, and the mask for adults. The length of the mask frame according to the present invention can be adjusted so that it can be applied to various masks having different dimensions.

In addition, the mask frame main body of the mask frame according to the present invention is divided into left and right two directions in the vicinity of the lower jaw of a person, and the lower holder portion connected or connected to the left and right divided parts is the lower jaw of the person. It is also possible to take a form in which two pairs are formed in the left and right portions.

Since the shape of a person's lower jaw differs from person to person, the lower part of the mask frame is branched in two directions, left and right, and a lower holder part is formed at the tip of the frame. By covering the lower jaw from both left and right sides in an L-shape, it can be brought into close and soft contact with the skin.

When the mask frame main body portion and the upper holder portion of the mask frame according to the present invention are separate parts, the fitting portion capable of joining and fixing the mask frame main body portion and the upper holder portion is the mask. A plurality of positions are provided in the vertical direction of the frame main body or the upper holder portion, and the fitting portion for joining and fixing the upper holder portion can be arbitrarily selected in the vertical direction to extend the overall length of the mask frame in the vertical direction. The height can be adjusted so that it can be adapted regardless of the vertical size of the mask.

Similarly, when the mask frame body portion and the lower holder portion of the mask frame according to the present invention are separate parts, the fitting portion capable of joining and fixing the mask frame body portion and the lower holder is The fitting part has a plurality of positions in the vertical direction of the mask frame main body part or the lower holder part, and the fitting part for joining and fixing the lower holder part is arbitrarily selected in the vertical direction of the entire mask frame. The length of the mask can be adjusted so that it can be adapted regardless of the size of the mask in the vertical direction.

In other words, a plurality of fitting portions for joining and fitting the mask frame body and the upper holder or the lower holder are arranged in the vertical direction of the mask frame, so that, for example, the fitting portions are located on the central side of the mask frame body. When the fitting portions are selected and joined and fitted, the length of the mask frame according to the present invention in the vertical direction is shortened as a whole. As a result, it is possible to harmoniously fit and fix a mask having a short length in the vertical direction (see FIGS. 3 and 4).

Conversely, when the fitting portions are selected from the upper and lower outer sides of the mask frame main body and are joined and fitted, the overall vertical length of the mask frame according to the present invention is increased. Thereby, it is possible to harmoniously fit and fix a mask having a long length in the vertical direction.

In addition, the first mask holding claw portion of the upper holder portion of the mask frame according to the present invention has a structure in which it is bent to sandwich the central portion of the upper side of the mask and is fixed by being latched to the hooking allowance of the upper holder. In addition, the second mask holding claw portion of the lower holder portion can be bent to sandwich the lower side portion of the mask and be fixed by being hooked to the hooking margin of the lower holder.

In other words, both the first mask holding claw portion of the upper holder portion and the second mask holding claw portion of the lower holder portion fold back and sandwich the upper side portion or the lower side portion of the mask, and the tip portion of the holding claw portion Since it has a structure in which the vicinity is locked and fixed by the hooking allowance of the holder, it can be easily attached to the mask with one touch, and can also be easily removed with one touch.

However, the mask frame according to the present invention does not strictly limit the structure of the holding claws of the upper and lower holders, and can be easily attached to the mask with a single touch as described above and can be removed with a single touch as well. As long as it is a presser claw portion structure, the conventional technology is also included. In other words, it is claimed that various structures are possible for the joining and fitting structure even in the prior art, and that the technical concept of the present invention includes correspondences based on the doctrine of equivalents.

The mask frame body of the mask frame according to the present invention may have a nose opening in the vicinity of the portion for receiving the tip of a person's nose and a mouth opening in the vicinity of the portion for receiving the person's mouth. .

Due to its structure, the mask frame main body comes into contact with the skin near the nose and mouth when the mask is worn. Therefore, in order to ensure sufficient clearances between the mask and the person's nostrils and mouth to facilitate breathing, the mask frame according to the present invention includes the nostrils and mouth of the mask frame main body. It is also possible to adopt a structure in which an opening is provided in the portion in contact with the . The present invention does not specifically limit the shape of the outer shape of the mask frame main body and the shape of the openings.

That is, since the entire structure of the mask frame according to the present invention is composed of the mask frame main body, the lower holder part, and the upper holder, various structures can be taken as a whole as described above. For example, the mask frame main body and the lower holder part, the upper holder integrated type or individual parts connection type, the entire mask frame divided into two types, the entire mask frame I-shaped type, inverted Y-shaped type, X-shaped type It can take various structures such as molds, and so on. The present invention does not limit the above-mentioned various forms and structures individually, and claims all forms and structures reflecting the technical ideas described in the claims as the scope of rights.

Similarly, the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the gist of the present invention. These are all part of this technical idea, including the correspondence in the doctrine of equivalents.

According to the present invention, a sanitary mask that can be easily used by anyone can reduce suffocation caused by wearing it for a long time, reduce rough skin and allergies by reducing adhesion to the facial skin, and can be used as a makeup mask. It is possible to provide a mask frame that prevents peeling of lipstick and prevents exposure of the nose and chin due to mask slippage.

In addition, it can be commonly applied to masks made of cloth or non-woven fabric, etc., of different sizes, and the safety and workability of wearing the mask can be greatly improved, and the economic efficiency such as manufacturing cost can be greatly improved. can provide a possible mask frame. In other words, it is possible to provide a mask frame that can achieve all of the problems and objects already described.
