Description

Technical Field

[0001] This utility model relates to a mask, and more particularly to a multifunctional leak-proof mask with multiple functions. Background Technology

[0002] The existing masks consist of a mask body and fastening straps, which is too simple and has many shortcomings.

[0003] Viruses are dangerous substances, highly contagious, and spread rapidly. According to the inventor's research, most masks currently on the market have air leaks, meaning that exhaled air or outside air can leak in or out through the mask's edges. The simplest test is to exhale forcefully into the mask while wearing it; you can detect the leaks around the edges. Even N95 masks will move or develop gaps when speaking or moving.

[0004] Doctors face various unknown risks, especially emergency room and outpatient doctors, so the protection provided by masks should be considered in the same way as protection against viral hazards. However, most hospital doctors currently wear ordinary disposable medical masks or disposable surgical masks, which have the leakage problems mentioned above. Furthermore, because these masks are uncomfortable to wear, not many people are willing to wear them, easily posing a risk of infection.

[0005] Existing masks still have several problems: one is poor fit to the face, especially considering the variety of face shapes required, resulting in inadequate protection and gaps. Some highly protective masks, such as N95 masks, are generally made of thick materials with poor breathability, which can have health side effects with prolonged wear. They are also relatively expensive and unsuitable for long-term epidemic prevention. Furthermore, they can interfere with speech and communication, and can feel stuffy. Therefore, a middle-ground solution for mask-based protective equipment is still lacking.

[0006] Wearing masks for extended periods can also cause pressure on the skin, resulting in marks, tears, and damage. Furthermore, excessive temperature and humidity inside the mask can lead to oily and sweaty skin, making the skin prone to allergies and even inflammation.

[0007] To protect against these hazards, masks should be worn for extended periods, taking full advantage of this prolonged contact with the face and mouth / nose. This allows beneficial or protective ingredients to come into contact with the skin or mouth / nose.

[0008] Current patent applications involve adhesive structures around the edges of face masks, but these have too many problems, lack practicality, and haven't been commercialized. A new approach is urgently needed.

[0009] There are currently several problems with wearing masks: First, there is a risk of leakage.

[0010] Therefore, after a long period of effort, the inventor studied various existing documents, existing technologies, and implementation examples of existing technologies, but found that none of them could solve these problems.

[0011] Current disposable masks have obvious loopholes in epidemic prevention. For example, if an infected person sneezes or coughs, droplets can enter through gaps in the mask, causing infection. Therefore, related supporting products have been included in the catalog of emergency innovative products for epidemic prevention and control, which can be searched in the search bar of the Guangzhou Municipal Science and Technology Bureau's official website. Summary of the Invention

[0012] Based on this, the present invention proposes a mask that solves the problems in the existing ones.

[0013] The technical solution of this utility model is implemented as follows: 1. Because the virus is very dangerous, masks also need other auxiliary sealing devices.

[0014] 2. Because viruses are very dangerous, it is necessary to have an extra layer of protection to inhibit bacteria and viruses.

[0015] To solve this problem, the idea of ​​using adhesive masks was considered. Many years ago, efforts were made to address the issue of mask sealing, and existing patent applications primarily proposed using adhesive-like substances such as silicone tape, double-sided tape, Velcro, and self-adhesive labels. This was because adhesives could solve the sealing problem and eliminate the need for ear loops to secure the mask. However, over the years, this solution has not been widely adopted due to numerous problems.

[0016] Tests revealed the following problems with medical adhesives: Adhesive tape, pressure-sensitive adhesive, and medical double-sided tape, while possessing strong adhesive power, often damage skin follicles. Experiments showed that, for example, when adhesive tape was used to attach a mask to the face, removing it resulted in the removal of many fine hairs, damaging hair follicles, irritating the skin, and easily causing inflammation and allergies. With pressure-sensitive adhesive, removing it left the adhered skin white, and compared to the surrounding unadhesive skin, it was evident that epidermal cells such as the stratum corneum had been torn away. This is especially problematic for the delicate skin on the face. Furthermore, pressure-sensitive adhesive and adhesive tape are ineffective at attaching fabric items like masks, easily detaching. Therefore, a type of adhesive is needed for direct adhesion between fabric and the human body, capable of securing masks to the skin without causing damage and even benefiting the skin.

[0017] There's a significant technical bias among industry insiders: many people believe that any adhesive on the market can be used to stick masks, but this isn't the case. Early testing of existing Velcro, double-sided tape, self-adhesive tape, silicone adhesive, gel tape, and even high-viscosity glass glue and some viscous skincare products (details of the tests follow) revealed that none of them worked. The most common problem was that the mask would detach from the skin on both sides and in the middle, leading to leakage. This is fatal for mask protection, as safety in hazardous environments requires a tight seal; leakage renders the entire protection ineffective. Therefore, these methods were essentially abandoned.

[0018] Many years ago, there were prior applications for structures that could be attached to the perimeter of face masks. While similar applications have been filed over the years, none have achieved practicality or industrialization, and they are not readily available on the market. Unable to purchase corresponding products, the inventors implemented the embodiments described in the prior applications and discovered that regardless of whether gel, silicone, silicone gel, or pressure-sensitive adhesive is used, it all involves a thin layer of adhesive. The human face has rich three-dimensional curves and undergoes facial movements such as speaking, resulting in unique stress distribution. This thin adhesive layer itself cannot deform. Even when combined with soft materials like gel, silicone, or silicone gel, the adhesive at each point can only move in a two-dimensional direction. Therefore, when masks are attached to the face using these structures, problems such as detachment, poor fit, wrinkles, and leaks are prone to occur, posing a risk of leakage and even the mask falling off the face. Furthermore, these structures have poor adhesion to non-woven fabrics and other rough surfaces.

[0019] Therefore, the prior patent applications did not achieve industrialization, lacked practicality, and such products were not available on the market. This utility model, through extensive research, discovered this important principle: the face has rich three-dimensional curves, requiring a structure and composition of adhesive that allows movement in three dimensions after the mask is applied to the face, especially immediately after application.

[0020] However, it was later discovered by chance that by adjusting the paste of some components to be non-flowing, it could stick to the mask, preventing it from falling off or leaking. Therefore, the importance of this non-flowing property for applying masks was discovered.

[0021] The inventor studied and explained it through mechanics and other methods. The toothpaste-like, non-flowing paste, or what could be called a Bingham fluid, is designed to be non-flowing. The reason toothpaste needs to be non-flowing is that when brushing, the toothpaste is squeezed onto the bristles of the toothbrush; if it were fluid, it would quickly flow into the bristles. Using a non-flowing paste for adhesion effectively utilizes atmospheric pressure, ensuring that the paste itself does not deform and its structure remains intact.

[0022] In addition, in order to solve the three major problems of wearing masks, a solution was found through countless experiments and tests, a brand-new type of protective product was created, a new connection relationship and structure was proposed, and the concept of mask paste was put forward.

[0023] There's another technical bias: people assume that the adhesive structure in the earlier patent application was also a thick layer. However, the inventor has studied this field and mechanics, and that's not the case. The adhesive structure in the earlier patent application only has a thin layer of self-adhesive that actually serves an adhesive function. If a mask had such a thick layer of self-adhesive, it would easily deform and be difficult to store. Also, removing it would leave a lot of adhesive residue. The appropriate unit for describing their thickness is micrometers. The mask paste proposed by the inventor is a new thing, a new connection relationship, and its appropriate unit for thickness is millimeters.

[0024] It can be said that masks are the most difficult to stick on properly. It's not so easy to stick a mask on your face because a mask is not simply a flat piece of paper stuck to your face. It needs to be stretched to cover your mouth and nose, which creates a stretching force, as well as the pulling force from facial movements such as talking.

[0025] The inventor believed that a new substance and bonding relationship should be used to solve this problem, and proposed a mask paste, a paste-like substance, especially one with no fluidity like toothpaste, as the best solution. This was mainly based on the following two points: First, the superior texture of this ointment lies in its capacity. 1. It can hold a large amount of active ingredients, allowing for larger particle sizes and longer-lasting effects. The ointment's large capacity allows for many functions, including the containment of numerous active ingredients, and even their reactions and transformations. In contrast, a thin adhesive layer makes it difficult for effective active ingredients to be released and reach the mouth and nose area.

[0026] 2. The ointment can prevent allergies and irritation. When you sweat, the pressure-sensitive adhesive is not breathable, and sweat cannot be discharged, which can easily irritate the skin and cause allergies. The ointment has a large capacity, so it can absorb sweat and moisture better. The ointment has a large capacity and can absorb and store the moisture inside the mask and the sweat and oil from the skin. In particular, the ointment uses water-soluble ingredients, which makes it even more effective.

[0027] Therefore, after the product was released, it was unexpectedly found to improve the stuffiness and suffocation caused by masks, thus improving breathing. Attached are reviews from medical staff at several top-tier hospitals who have personally used the product. After expert evaluation, it was included in the catalog of innovative emergency products for epidemic prevention and control.

[0028] Second, this type of paste utilizes various forces, including atmospheric pressure, thus significantly reducing the amount of adhesive needed. Its non-flowing nature ensures that the paste itself does not deform or its structure is not damaged, allowing it to utilize atmospheric pressure.

[0029] Therefore, the inventor's earliest technical solution was to make the functional layer (adhesive structure) on the mask into a functional layer paste like toothpaste, with a certain degree of stickiness. The weaker adhesiveness would seal the gaps, while the stronger adhesiveness would stick the mask in place without the need for a fixing strap.

[0030] This ensures that the mask fits snugly against the face and / or fills the gaps between the mask and the face.

[0031] Furthermore, the addition of a film-forming agent enhances the effect significantly, a principle the inventor calls the "root principle." This allows the cream to penetrate the skin's crevices and fill in facial grooves. Once the film-forming agent solidifies, it adheres firmly, like tree roots placed in the facial grooves. The use of a film-forming agent solves three problems: first, it achieves the "root principle" effect; second, it is easily removed from the skin after drying; and third, it helps absorb and store sweat and oil.

[0032] In addition, the use of such a paste has the following significant advantages.

[0033] 1. The connection between the mask and the face ensures even stress distribution across the mask, reducing or preventing stress concentration and eliminating the risk of detachment or separation. 2. The face has varied curves, resulting in varying distances between the mask and the face. A paste is ideal for connecting these uneven surfaces, ensuring every point is connected. Compared to previous technologies, this significantly increases the contact area, greatly reducing adhesive usage while maintaining the same adhesive strength. This new connection structure drastically reduces adhesive usage, allowing for more skin-care ingredients. This transforms the mask adhesive from an adhesive to a skin-care product – a qualitative leap. Prioritizing skincare with secondary adhesive properties facilitates prolonged use and truly popularizes cordless masks that don't require straps.

[0034] The beneficial effects of this utility model are: it provides more thorough and comprehensive protection, and has multiple functions, resulting in better protective efficacy. This is thanks to the proposed new structure, which prevents the effectiveness of medicines and other active ingredients from being affected when stored together with the mask.

In this application, the use of the singular includes the plural, and unless otherwise expressly stated, the use of the terms “and” and “or” means “and / or”, unless otherwise stated. Furthermore, the use of the term “comprising” and other forms such as “including” and “contains” shall be considered non-exclusive.

[0039] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] The protective mask products of this utility model refer to: masks, related components on masks, mask-related products, or respiratory-related products, including small masks for the nose and large masks including face shields.

[0042] The adhesive properties referred to in this invention also refer to the bonding strength of the adhesive, which can be reflected in the peel strength.

[0043] Unless otherwise specified, the extract referred to in this utility model refers to all extractable substances that are harmless to the human body.

[0044] The active ingredients and functional ingredients referred to in this utility model are functional substances.

[0045] The following are examples of face masks: The inventor can also implement this using existing publicly available technology, and easily obtain some of this adhesive paste. Then, combine it with a mask structure. Of course, the less fluid the adhesive paste is, the better the effect.

[0046] The reason why existing masks, especially flat masks, leak air from the sides is because the mask material is too thin, mainly around the edges. The solution is to increase the thickness of the mask's perimeter by adding several layers of filter material around the outer edge.

[0047] The outer insulating layer of the mask extends inward and wraps around the inner surface of the mask to form a long edging.

[0048] When a mask is worn on a person's face, the mask and the person's face form a sealed area, and the effective substances and volatile components in the liquid, solid, and ointment in the mask bag will be fully distributed in this sealed area.

[0049] To achieve the same leak-sealing effect as adhesive tape, masks can also be applied in this way: The outer waterproof layer of the mask can also be multiplied with other layers, extending and wrapping inwards to form a long edging around the inner surface of the mask. As shown in the diagram, a leak-proof ring 24 is fixed to the inner surface of the mask. The outer edge of the leak-proof ring is tightly sealed to the perimeter of the mask, and the inner edge 25 of the leak-proof ring is raised relative to the inner surface of the mask. When a person wears the mask, the raised inner edge of the leak-proof ring comes into contact with the skin, thus sealing any leaks. The leak-proof ring can be made of the mask's filter material, or an impermeable material, or even a flexible material.

[0050] Or, since there is generally no air leakage at the bottom of the mask, a leak-proof ring is not needed at the bottom of the mask. The leak-proof ring is only retained on the left, top and right sides of the mask.

[0051] For example, square masks do not have a leak-proof ring at the bottom; the leak-proof ring is only present on the left, top, and right sides of the mask.

[0052] You can also fill the space between the mask and the leak-proof ring with a substance, such as adhesive tape, to make the inner edge of the leak-proof ring curl up more.

[0053] Adhesive can be applied to the material between the leak-proof ring and the mask; or a solvent-absorbing and swelling material, such as water-absorbing resin, can be placed in the material between the leak-proof ring and the mask. After applying adhesive or absorbing the moisture exhaled from the mouth and nose, the material expands, thereby continuously enhancing the effect of the baffle in filling the gaps.

[0054] The adhesive contains ingredients that can raise the temperature, i.e., heat-generating substances, to promote the volatilization of active ingredients and functional substances. The heat-generating substance composition is combined together on one adhesive, or the heat-generating substance composition is separately placed on two adhesives. After opening the packaging, the adhesive is applied to protective masks. When a person puts on the mask, the heat-generating substance begins to heat up, and the mask and the person's mouth and nose area form a sealed area, allowing the active ingredients to volatilize well and act on the respiratory system.

[0055] When a person wears a mask, the mask and the area around the mouth and nose form a sealed zone, allowing the active ingredients or substances to evaporate and act on the respiratory system effectively. It can also promote the evaporation of non-volatile drugs and other active substances, enabling them to be inhaled through the respiratory system.

[0056] Ending: This invention refers to adhesive properties similar to those of ordinary glue, that is, the average peel strength of ordinary solid glue sold in stationery stores.

[0057] The above examples of masks with fixing straps can be removed if the mask can be fixed to the face using adhesive tape, mask stickers, functional layers, or double-sided tape.

[0058] Since adhesive paste can be applied to face masks, the same substances contained in adhesive paste can also be contained in face masks.

[0059] For all the above-mentioned coatings, some components of the heating composition are located in the space between the mask and the face, in the space formed by the mask or (compared to ordinary masks) additional components (such as baffles, leak-proof rings) that do not contact the skin, or in liquid or paste-like adhesives containing additional heating components. The heating composition begins to generate heat by bringing the two into contact with each other; the active ingredients and functional substances are located in the space between the mask and the face, in the space formed by the mask or (compared to ordinary masks) additional components that do not contact the skin, or in adhesives; Alternatively, all components or the heating layer of the heating composition may be located in the space between the mask and the face, on the inner or outer surface of the mask or (compared to ordinary masks) that does not contact the skin. Upon opening the package, the heating composition generates heat. The active ingredients and functional substances may be located in the space between the mask and the face, on the inner or outer surface of the mask or (compared to ordinary masks) that does not contact the skin, or may be contained in an adhesive paste. When a person wears a mask, the mask and the area around the person's mouth and nose form a sealed zone, allowing the active ingredients or functional substances to evaporate and act on the respiratory system effectively.

[0060] A heating layer containing a heating element can be incorporated. The heating composition can also be one that generates heat through physical processes, such as compression, for example, a composition containing calcium oxide and magnesium chloride. Far-infrared heating materials can also be used. Heat-storage heating materials can also be used. Alternatively, a device with a directly fixed heating element can also be employed.

[0061] The original intention of this invention is to allow the active ingredients and functional substances to volatilize in the mask and the sealed mask in the mouth and nose area, so that the temperature of the heating composition can be greatly increased.

[0062] For ease of use, adhesive tape is pre-installed on various types of masks, creating masks with adhesive tape. Adhesive tape can also be pre-installed on various types of nose shields, creating nose shields with adhesive tape.

[0063] All of these structures are additional components added to existing ordinary disposable masks or N95 masks.

[0064] The embodiments of this utility model include an additional bag-like structure. The mask bag can be placed on the mask itself or added to other structures, such as baffles or leak-proof rings. To facilitate inhalation through the respiratory system, when the bag-like structure contains solid powdered active ingredients or drugs, the particle size of the powder should be as small as possible, for example, around 5 μm, preferably in the range of 0.5–5.0 μm. The opening of the bag faces the mouth and nose area and is in an open state. Because the mask and the human mouth and nose form a sealed space, when the human breathes, the exhaled air will blow the powder in the bag-like structure, promoting the formation of a powder mist. When inhaling, the powder mist is inhaled into the respiratory system.

[0065] A desiccant can be placed on the bag wall to keep the active ingredient in the solid powder dry. A fine metal wire can also be led from the bag to the area that contacts the skin, thus discharging static electricity from the solid powder through the human body. This promotes the flowability of the solid powder. The bag may also include a heating element, or the bag wall may be adjacent to a heating material, which can further maintain the dryness and flowability of the solid powder.

[0066] The various active ingredients and functional substances mentioned in this invention, including drugs, can also be supplied as solid powders. This differs from existing inhaled drug delivery methods, which involve inhaling a large amount of powder at once, irritating the respiratory system. This invention, utilizing a mask and its novel structure, makes inhaled drug delivery a slow and continuous process, which is more conducive to absorption and beneficial to the respiratory system.

[0067] This invention innovatively utilizes added leak-proof structures and components to prevent mask leakage, while cleverly using them to contain heat-generating substances, thereby promoting the volatilization of active ingredients and functional substances to assist in antibacterial or antiviral effects. It provides two types of protection and is highly practical.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely examples of several implementations of the utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
