Description

[Technical Field]

[0001] The present invention relates to a mask inner that has the functions of preventing glasses from fogging up, training facial muscles, and preventing the inhalation of fine dust particles such as pollen. [Background technology]

[0002] For example, for people for whom anti-allergy medications are not very effective, people who want to reduce their medication due to a chronic illness, or people who simply dislike taking medication, wearing a sanitary mask is the first thing they consider to be a countermeasure against hay fever.However, when wearing a mask in combination with glasses, the lenses tend to fog up, which can be stressful.Also, a certain amount of pollen inevitably enters through the gap between the sanitary mask and the skin on the face, and there is also the sense of futility that comes with having to endure wearing a sanitary mask for long periods of time.

[0004] The invention in Patent Document 1 (the "fine dust absorber" invented by the inventor) uses a stretchable material, but this was because the inventor placed importance on ease of use. However, it was necessary to prepare a material that was simply made from the stretchable material (for example, the sheet used to make bandages) in the form of double-sided tape, and mass production of this would require building a new production line, which would require a huge investment. Therefore, a realistic production method was considered in which the double-sided tape was attached to the sheet used to make the bandages, but the double-sided tape available on the market is not stretchy, making it unavoidably uncomfortable to use. Another disadvantage is that it does not have an anti-fogging function for glasses, which makes it very stressful for people who use glasses to continue using it over the long pollen season. (Incidentally, even if a hood portion that guides exhaled air downward, which is expected to have an anti-fogging effect for glasses as newly invented in this invention, were formed, it would quickly crumple and not retain its shape, making it difficult to realize, for example, with the sheet used to make bandages.) Therefore, aiming to commercialize it using elastomer resin, Repeated wearing experiments with prototypes with hooded sections revealed that while there was no problem with absorbing fine dust particles such as pollen, the adhesive strength to the facial skin gradually decreased with sweat, resulting in breath leakage from the area below the eyes, making it difficult to achieve anti-fogging effects for eyeglasses. The inventors then reversed their approach and repeatedly tested wearing prototypes using non-elastic materials. They confirmed that the hooded section was easy to form, adequately shielded the area below the eyes (hereinafter referred to as the "breath shield section"), and at the same time, effectively guided breath downward along the hooded section, preventing eyeglasses from fogging. An unexpected benefit was that the use of non-elastic materials placed a certain strain on the facial muscles when laughing, talking, or simply going about daily life while keeping the facial skin in place, which ultimately served to train the facial muscles and potentially improve sagging around the cheeks and mouth, for example.

[0005] The invention of Patent Document 2 is an invention in which the mask is attached from above to the edge of the mask worn on the face and over exposed skin, and is not an invention in which it is attached to the inside of a sanitary mask like the present invention.Furthermore, it does not have the function of training facial muscles or the function of suppressing the inhalation of fine dust.

[0006] The inventions of Patent Documents 3 to 5 are inventions that add some kind of structure that has the function of preventing glasses from fogging to the sanitary mask side, but are not inventions that adhere to the facial skin side like the present invention.Furthermore, they do not have the function of training facial muscles or the function of suppressing the inhalation of fine dust.

[0007] The invention of Patent Document 6 is described as having an anti-fogging effect on glasses when adhered to the skin of the face, but since it does not have the function of directing exhaled air downward like the present invention, its effect must be considered extremely small. Furthermore, the adhesive layer 2 of the invention can be considered to correspond to the facial-side adhesive sheet 10 in the light of the present invention, but since it does not have double-sided tape 22, no gap is formed with the sanitary mask, and therefore it cannot adsorb fine dust that is sucked in through the gap.

[0008] The invention in Patent Document 7 is a smile formation aid for learning the state of facial muscles when smiling through physical experience, not an invention for training facial muscles. In addition, it cannot be attached inside a sanitary mask, and does not have the function of preventing glasses from fogging up or preventing the inhalation of fine dust.

[0009] The inventions of Patent Documents 8 to 13 are inventions in which the mask is attached to the face by covering the back of the head with a belt or the like, but are not inventions in which the mask is attached directly to the face like the present invention. In addition, they cannot be attached inside a sanitary mask, and do not have the function of preventing glasses from fogging up or preventing the inhalation of fine dust.

[0010] The inventions of Patent Documents 14 to 19 are either small enough to fit inside a sanitary mask, or are themselves sanitary masks, but they basically utilize the properties of elastic materials, not the properties of non-elastic materials as in the present invention. Furthermore, they do not have the function of preventing glasses from fogging up or the function of preventing the inhalation of fine dust particles. [Means for solving the problem]

[0011] The present invention provides a mask inner made of an adhesive sheet that is attached to the inside of a sanitary mask and is characterized by having a hood part with breathing holes corresponding to the nose and mouth, and an exhalation shield part that adheres to the facial skin below the eyes.

[0012] The present invention provides a mask inner characterized in that a non-elastic adhesive sheet is used as the adhesive sheet, and the adhesive sheet adheres to the facial skin.

[0013] The present invention provides an adhesive surface on the side of the adhesive sheet that comes into contact with the sanitary mask, and the pollen and fine dust particles that are sucked in through the gap between the sanitary mask and the adhesive surface are adsorbed onto the adhesive surface. The present invention provides a mask inner characterized by the above.

[0014] The present invention provides a mask inner characterized in that an uneven structure is formed on the adhesive surface. [Effects of the Invention]

[0015] According to the present invention, the exhalation shield part that adheres to the facial skin below the eyes prevents exhaled air from leaking upward, and the hood part guides the exhaled air downward, preventing glasses from fogging up.

[0016] According to the present invention, by fixing the facial skin using a non-elastic material, the subcutaneous fat acts as a cushion and moderately restricts the facial muscles, so that in this state, you can laugh, talk, and in other words, train your facial muscles without being restricted by time by going about your daily life (for example, you can expect to see improvement in sagging around the cheeks and mouth just by going about your daily life, without being restricted by time such as going to a beauty salon or taking the trouble to train your facial muscles in front of a mirror).

[0017] According to the present invention, by providing an adhesive surface on the side of the adhesive sheet that comes into contact with the sanitary mask, fine dust particles that are sucked in through the gap between the sanitary mask and the adhesive surface can be adsorbed onto the adhesive surface, preventing them from being sucked into the body (for example, this could be another option for people who suffer from hay fever and for whom anti-allergy medication is not very effective, or for people who want to reduce medication due to a chronic illness, or for people who simply dislike medication).

[0018] According to the present invention, by forming an uneven structure on the adhesive surface that comes into contact with the sanitary mask, the flow of intake air passing near the facial skin can be randomized, further enhancing the ability to adsorb fine dust (for example, there is a possibility of achieving high effectiveness in adsorbing fine dust such as bacteria, viruses, yellow sand, and PM2.5).

[0019] According to the present invention, the mask fits inside a sanitary mask, so it looks completely natural even when used daily. Furthermore, since it can be used to combat pollen while simultaneously training facial muscles, it can motivate people who are troubled by sagging skin around the cheeks and mouth to get through the depressing pollen season in a positive way, and they are less likely to give up after three days.

[0020] According to the present invention, there is a high possibility that mass production can be performed at low cost, which may lead to savings in costs for, for example, anti-allergic drugs and medical treatments, or costs for cosmetics and beauty treatments.

[0022] First, let us explain the process that led to the present invention. As described in

[0004] , a prototype was created using a non-elastic material to explore its usefulness (specifically, a prototype was created by attaching double-sided tape to both sides of a commercially available clear file material, and then attaching surgical tape to one side of the tape so that the adhesive side of the surgical tape was exposed. The inventor, who is also a sufferer of severe hay fever, served as the test subject and wore the prototype for almost 24 hours a day for one season). It was found that the hood portion was easy to form and its adhesive strength did not decrease with sweat, so the underside of the eyes was accurately shielded and breath did not leak from that area (the breath shield portion) and cause glasses to fog up. Next, although it is true that the facial skin is fixed in place and is uncomfortable to use, it was found that there is an advantage in that the facial muscles are trained by deliberately laughing and talking in that state, in other words, by going about one's daily life (specifically, as the facial muscle training progressed, the discomfort became less of a concern, and the subject's cheeks and sagging around the mouth almost disappeared. Incidentally, the subject was 63 years old at the time.) However, when used for long periods of time, it was found that the area around the cheeks below the corners of the eyes was prone to coming into contact with the edge of the clear file material, causing pressure wrinkles, and for the same reason, the jaw, which is subject to a lot of stress when moving the mouth, was accompanied by slight pain and left slight pressure marks. It was found that to solve this problem, it would be better to slightly bend the area around that point so that the edge was raised above the facial skin. Furthermore, since it was found that the bell-shaped cross section of the hood puts pressure on the nostrils and makes breathing difficult, it was found that in order to solve this problem, it is better to fold the hood from the area corresponding to the inner corner of the eye to the area corresponding to the corner of the mouth so that the cross section is bowl-shaped before use. Furthermore, it was also thought that in order to further enhance the fine dust absorption effect of the present invention, it must be better to form countless uneven structures on the adhesive surface so that the intake airflow flowing near the facial skin flows randomly (in theory, by simply researching the optimal size and arrangement of the unevenness, it is possible to improve the absorption effect not only of pollen but also of fine dust such as bacteria, viruses, yellow sand, and PM2.5).

[0023] Figure 1 shows the basic structure of a mask inner 1x. Specifically, double-sided tape 22 is attached to both sides of non-stretchable sheet 11, and facial-side adhesive sheet 10 is attached to one side of the sheet in the direction that the adhesive side of facial-side adhesive sheet 10 is exposed. Release papers 20 and 21 are attached to both sides of the sheet and are cut into a desired shape, with pairs of fold lines 30a, 31a, and 32a on the left and right sides at desired positions. (Note that fold lines 30a, 31a, and 32a can be created in two ways: by pre-creasing the folds or by printing them on release paper 21. The former has the advantage of being easy to fold, while the latter has the advantage of allowing the fold position to be finely adjusted to fit the user's face.)

[0024] FIG. 2 shows step 1 of putting on the mask inner 1, illustrating the process of folding the mask inner 1x along the fold lines 30a and 32a (or near the fold lines 30a and 32a) to create a pair of valley folds 30 and 32 on the left and right sides.

[0025] FIG. 3 shows a second step of wearing the mask inner 1, in which the fold line 31a (or 10 illustrates a process of folding the paper along the crease line 31a (or near the crease line 31a) to form a pair of valley creases 31 on the left and right.

[0026] FIG. 4 shows the third step of putting on the mask inner 1, and is a view of the mask inner 1x with the valley folds 30, 31, and 32 formed.

[0027] FIG. 5 shows step 4 of putting on the mask inner 1, in which the release papers 20 and 21 of the mask inner 1x with the valley folds 30, 31 and 32 formed are peeled off to expose the mask inner 1.

[0028] FIG. 6 shows the mask inner 1 in step 5 of putting on the mask inner 1, and is a view of the mask inner 1 in a state where the valley folds 30, 31, and 32 have been formed.

[0029] FIG. 7 shows a procedure 6 for putting on the mask inner 1, in which both ends of the mask inner 1 are opened so as to be in a positional relationship on the same plane, thereby forming the hood portion 1a.

[0030] FIG. 8 shows step 7 of putting on the mask inner 1, in which both ends of the mask inner 1 are bent in an L shape while remaining in the same plane, to form the hood portion 1a into a sharper semi-conical shape.

[0031] Figure 9 shows step 8 of putting on the mask inner 1, which shows the procedure of attaching the mask inner 1 to the facial skin 12 by fitting the hood portion 1a with the user's nose and using the adhesive force of the facial skin-side adhesive sheet 10.

[0032] FIG. 10 is a diagram showing the state in which the mask inner 1 is worn, and explains that the facial skin-side adhesive sheet 10, which includes the inside of the hood portion 10a and the exhalation shield portion 10a, adheres to the facial skin 12, including the facial skin on the surface of the user's nose and the facial skin below the eyes, and that in this process, the band-shaped area corresponding to the chin is overlapped and attached to form the breathing hole 1b.

[0033] FIG. 11 is an explanatory diagram of the effect of the valley folds 30 and 32. Specifically, it is a front view (a) and (b) showing that when there are no valley folds 30 and 32, the pressed wrinkles 30x and the stress marks 32x are likely to occur, and a front view (c) and (d) showing that when there are valley folds 30 and 32, the pressed wrinkles 30x and the stress marks 32x are unlikely to occur.

[0034] Figure 12 is an explanatory diagram of the effect of the valley folds 31. Specifically, Figure 12 (a) explains that when there are no valley folds 31, the cross section of the part that becomes the hood-like structure becomes bell-shaped, generating a vector 1x that compresses the nostrils, and Figure 12 (b) explains that by forming the valley folds 31, a bowl-shaped hood portion 1a is formed, which does not compress the nostrils.

[0035] FIG. 13 shows step 9 of putting on the mask inner 1, in which the sanitary mask 40 is about to be put on over the mask inner 1 that has been stuck to the facial skin 12.

[0036] FIG. 14 shows the procedure 10 for putting on the mask inner 1, in which the sanitary mask 40 is lightly pressed from above with both hands to make it fit snugly.

[0037] 15 is an explanatory diagram of the anti-fogging effect on eyeglasses. Specifically, the exhalation shield portion 10a prevents the exhalation airflow 100 from leaking upward, and the exhalation airflow 100 is guided by the hood portion 1a and passes through the breathing hole 1b, passes through the sanitary mask 40, and is exhausted downward, making it difficult for the exhalation airflow to flow toward the eyeglasses 50.

[0038] FIG. 16 is an image showing the state of training facial muscles using the mask inner 1. Specifically, image (a) shows a state of laughing and image (b) shows a state of shouting. The image (b) shows that the facial skin 12 is fixed while making facial expressions, which places stress on the facial muscles and trains them.

[0039] 17 and 18 are explanatory diagrams of the adsorption mechanism of fine dust particles such as pollen. Specifically, these diagrams show how fine dust particles 200 (e.g., pollen) flow in on the intake airflow 101 through gaps between the sanitary mask 40 and the double-sided tape 11, created by the nap 41, but most of the fine dust particles are adsorbed by the adhesive force of the double-sided tape 11. Figure 17 is a front view showing the overall concept, and Figure 18 is a cross-sectional view explaining the mechanism in more detail.

[0040] FIG. 19 is a diagram showing the basic structure of a mask inner 2 provided with a porous double-sided tape 22a as an adhesive surface in order to enhance the effect of adsorbing fine dust particles.

[0041] FIG. 20 is an image diagram showing that the intake airflow 101a flows randomly due to the concave structure 22b and convex structure 22c of the mask inner 2 equipped with the porous double-sided tape 22a, making it easier for the fine dust particles 200 to be adsorbed by the porous double-sided tape 22a.

[0042] Figure 21 is an illustration of the case where porous double-sided tape 22a and double-sided tape 22 are attached together to further increase the adsorption power of the mask inner 2 for fine dust particles 200 (incidentally, the mechanism by which the intake airflow 101a flows randomly is the same as in Figure 20).

[0043] Figure 22 suggests the next step, assuming that the present invention has been refined to create a product with sufficient functionality for preventing the inhalation of bacteria and viruses. Specifically, the present invention was originally conceived with the goal of preventing the inhalation of bacteria and viruses to prevent illness, but the benefits are limited to the user of the invention. Therefore, it is suggested that an exhaled breath sterilization device A that can be enjoyed by an unspecified number of people would be even better. (The structure is as shown in Figure 22, but to put it very simply, the system works as follows: an inflow airflow 102 is constantly generated in the gap between the mask 40 and the mask cover A1 via a duct A2 driven by an exhaust fan A4; exhaled breath is sterilized by a sterilizer A3 and then exhausted to the surrounding space as an exhaust airflow 103. Incidentally, because the exhaust airflow 103 is exhausted away from the face, it does not fog up glasses, so it is possible to use it in conjunction with the invention described in Patent Document 1, which takes user comfort into consideration.) The reason for suggesting this is that, for example, if one comes into close contact with a person with a disease of severity risk Class 2 or higher, even if the present invention could minimize the risk of infection, one would still be forced to restrict going out. However, simply wearing breath sterilization device A would almost completely eliminate the possibility of a cluster, which could potentially resolve the absurdity of, for example, social workers and other lifeline workers being forced to restrict going out even if they are not showing symptoms. In other words, if the present invention can minimize the risk of infection and breath sterilization device A can minimize the risk of infection to others, it would be possible to physically respond to new pandemics (such as the new COVID-19) whose occurrence is unpredictable, and this could provide a new option for people who do not want to get vaccinated (or it could buy time for the development of a safer and more secure vaccine).
