Description
Mask containing oxygen-generating composition and method for manufacturing same
[0001] The present invention relates to a mask capable of supplying oxygen to a user by generating oxygen through a reaction when an emergency situation occurs by including an oxygen-generating composition in a container, and a method for manufacturing the same. In addition, the present invention relates to a protective mask capable of rapidly generating and supplying oxygen in the event of an emergency disaster such as a fire or explosion, thereby preventing casualties by blocking the inflow of toxic gases into a person's respiratory system. In addition, the present invention relates to a mask capable of smoothly supplying oxygen to a user in an oxygen-deficient situation such as a high-altitude area, and capable of urgently providing oxygen in an emergency situation due to oxygen deprivation to prolong the life of the user.
[0002] In the event of a disaster such as a fire or explosion, the primary cause of casualties is not the direct flames, but rather the smoke and toxic gases that spread through the air. Furthermore, vulnerable citizens frequently miss the golden evacuation window due to inhalation of toxic gases or smoke suffocation.
[0003] In a disaster situation such as a fire or explosion, it is important to avoid the flames, but first and foremost, cover your nose and mouth to prevent inhalation of toxic gases and smoke containing a large amount of toxic substances, and prevent life-threatening situations such as brain damage or cardiac arrest due to lack of oxygen, thereby securing the golden time and surviving until rescue teams can arrive, ultimately preventing casualties.
[0004] In the past, it was common to cover the mouth and nose with a wet towel in an emergency to prevent inhalation of toxic gases and smoke. However, finding a towel and wetting it in the event of a disaster is cumbersome and delays the preparation process, which can lead to dangerous situations where toxic gases are inhaled. Furthermore, covering the respiratory system with a towel can make it difficult for young children or the elderly to breathe normally, and evacuees have difficulty actively responding to the initial disaster or quickly evacuating while keeping the towel in close contact with their hands and respiratory system.
[0005] There is a need for a product that can effectively block toxic gases or smoke that can enter the human respiratory system while also quickly supplying oxygen to the user, thereby extending their survival time.
[0006] Meanwhile, in high altitudes, oxygen becomes scarce as altitude increases. This can cause dizziness and, in severe cases, loss of consciousness or even death. Climbers climbing extremely high mountains around the world, such as the Himalayas, are particularly susceptible to oxygen-depleted environments. To address this, they often carry oxygen cans, which are stored in separate cans. However, these cans are bulky and heavy, making them difficult and inconvenient to carry for extended periods of time while climbing. Therefore, there is a need for a product that is easy to carry while also providing emergency oxygen in the event of a health emergency due to oxygen deficiency.
[0007] Accordingly, the problem to be solved by the present invention is to provide a mask and a method of manufacturing the same that can effectively block toxic gases or smoke that may enter the respiratory system of a person in an emergency situation while quickly supplying oxygen to the user, thereby extending the survival time.
[0008] In addition, we aim to provide a mask that is easy to carry and a method for manufacturing the same that can immediately supply oxygen when needed in high-altitude environments such as oxygen-deficient areas.
[0009] In addition, we aim to provide a mask that can be worn by multiple people with various face shapes and sizes and a method for manufacturing the same.
[0010] In addition, the present invention aims to provide a mask and a method for manufacturing the same, which prevent undesired generation of oxygen even when stored for a long period of time by maintaining excellent airtightness before use of an oxygen generating material sealed and stored in an oxygen storage container.
[0011] In addition, the present invention aims to provide a mask and a method for manufacturing the same, which have excellent durability and can prevent other components combined with the filter of the mask from being unintentionally separated or damaged.

[0056] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0057] FIG. 1 illustrates a view of a mask according to an embodiment of the present invention viewed from one direction, FIG. 2 illustrates a view of a mask according to an embodiment of the present invention viewed from another direction, and FIG. 3 illustrates a view of a mask according to an embodiment of the present invention viewed from a direction in which a user wears the mask.
[0058] Referring to FIGS. 1 to 3, a mask according to one embodiment of the present invention includes a filter sheet (100), an oxygen generating container (500) coupled to the filter sheet (100), an oxygen generating material (10) stored in a sealed state inside the oxygen generating container (500), and a wearing strap (200) connected to both ends of the filter sheet (100), wherein the wearing strap (200) includes at least two first wearing straps (210) and second wearing straps (220) of different lengths.
[0059] The mask of the present invention can be used in dangerous disaster situations such as fires. In this case, it can block the inflow of toxic gases into the user's respiratory system, and for this purpose, a separate blocking filter placed on the filter sheet (100) can be additionally included. Furthermore, the filter sheet (100) can contain a liquid natural extract to provide a sense of security to the user while blocking harmful gases. Furthermore, the mask of the present invention can be used to urgently supply oxygen to climbers in emergency situations in oxygen-poor high-altitude areas, or to supply oxygen to those in need of oxygen through a reaction. The filter sheet of the mask used for this purpose may not contain a separate liquid extract. The mask of the present invention can provide oxygen to the user even in an oxygen-free environment by opening the oxygen generating container only when necessary, and the oxygen generating material generates oxygen through a reaction. Furthermore, it occupies a very small volume, making it easy to store and carry, making it very convenient for the user.
[0060] The filter sheet (100) may be formed in a state in which the first surface (110) and the second surface (120) are bonded to each other. In addition, the filter sheet (100) may have various filter layers as needed. For example, the filter sheet (100) may include a first layer made of a material including rayon, a second layer made of a material including activated carbon in a polypropylene material, a third layer made of a melt-blown filter including a polypropylene material, a fourth layer made of a material including activated carbon in a polypropylene material, and a fifth layer made of a material including rayon. By providing the filter sheet (100) in a state in which the first to fifth layers are sequentially arranged, it is possible to block external harmful gases. That is, it is possible to filter harmful gases such as carbon dioxide, formaldehyde, sulfur dioxide, nitrogen dioxide, and ammonia. However, the present invention is not limited thereto.
[0061] The above filter sheet (100) may include a liquid natural substance extract. The natural substance extract may include at least one selected from the group consisting of propolis extract, green tea extract, tea tree extract, lavender extract, rosemary flower extract, peppermint extract, corn mint leaf extract, matricaria extract, and water lily flower extract.
[0062] The mask can perform the function of blocking harmful gases by the above extract, and can be used as a gas mask. The filter sheet (100) that functions as a harmful gas filter layer contains a natural extract, so that it can block external harmful gases, prevent harmful gases from entering the user's respiratory system in an emergency situation such as a fire, and generate oxygen from an oxygen generating substance into the user's respiratory system, thereby allowing the user to survive for as long as possible. Furthermore, the mask of the present invention has a wearing strap (200) attached to both ends so that it can be hung on both ears of the user, thereby blocking harmful gases and supplying oxygen while allowing the user to evacuate more conveniently without using their hands.
[0063] Meanwhile, the filter sheet (100) may contain, in addition to the natural extracts, at least one ingredient selected from the group consisting of boswellia, ylang-ylang, cinnamon, neroli, bergamot, lemongrass, sweet orange, lavender, rose, rosemary, clary sage, Roman chamomile, and peppermint essential oils, and these extracts may be additionally used. By impregnating the filter sheet (100) with the extracts, it is possible to provide a sense of stability to the user and block toxic gases together with the oxygen generated from the oxygen generating material.
[0064] More specifically, the above Boswellia essential oil is made from the resin of trees of the genus Boswellia, and its main common components are a-Pinene, Limonene, a-Thujene, Myrcene, Sabinene, and Para-Cymene, which have anxiolytic properties and can affect sleep and wakefulness behavior.
[0065] In addition, the above ylang ylang essential oil can be extracted by distilling the flowers and stems of the ylang ylang tree, and is composed of 150 molecules including monoterpenes, sesquiterpenes, aliphatic compounds, phenylpropanoids, and nitrogen-containing compounds, and the main components Benzylbenzoate, Linalool, and Benzyl Alcohol can help relieve anxiety and have a sedative effect.
[0066] In addition, the above cinnamon essential oil is extracted from the brown bark of the Cinnamomum Verum tree, and most of its components are phenolic compounds, and the main active compounds of sesquiterpene and monoterpene hydrocarbons control the secretion of adrenaline, which helps treat depressive disorders and provides a sense of stability to the user.
[0067] In addition, the above neroli essential oil is obtained by distilling the flowers of the bitter orange tree and is rich in limonene, b-myrcene, and b-pinene, which can significantly reduce stress levels and have an excellent effect in relieving menopausal symptoms.
[0068] Additionally, the aforementioned bergamot essential oil is extracted from the exocarp and pith of the bergamot fruit and is primarily composed of limonene, linalyl acetate, and linalool. These compounds can minimize symptoms of stress-induced anxiety and mild mood disorders. Bergamot essential oil possesses anxiolytic and antidepressant properties, which can provide users with a sense of stability.
[0069] In addition, the above lemongrass essential oil is obtained by hydrodistillation from the leaves of lemongrass, and is mostly composed of Citral such as Neral and Geranial, and the compounds of b-Myrecene, Limonene, Citronellol, Geraniol, 1,8-Cineole, Nerole, a-Terpineol, Burneol, Eugenol, Geranyl Acetate, and Elemicin contained in the components can exhibit a significant effect of reducing anxiety and subjective tension.
[0070] In addition, the above sweet orange essential oil is obtained from the bark of the sweet orange tree by cold pressing with highly volatile compounds such as d-Limonene, b-Myrcene, a-Pinene, Sabinene, Linalool, Geranial, and Neral, and can significantly reduce the concentration of oxyhemoglobin in the right prefrontal cortex and increase a feeling of comfort, thereby providing powerful anxiety relief.
[0071] In addition, the above lavender essential oil is extracted from lavender flowers by steam distillation, and its main compounds are Linalyl Acetate, Linalool, Lavandulyl Acetate, Myrcene, Terpinen-4-ol, Terpineol, cis-Linalool Oxide, trans-Linalool Oide, and Ocimene. Lavender essential oil can treat mild stress and anxiety, and has a significantly beneficial effect on the quality and duration of sleep, so it can be effective in alleviating symptoms of anxiety disorders.
[0072] Additionally, the above rose essential oil can be obtained by distilling the flowers of Rosa Damascena. The majority of the components of rose essential oil are monoterpene alcohols, and other components such as 2-Phenethyl alcohol, citronellol, geraniol, methyl eugenol, and eugenol can significantly improve sleep quality and contribute to an anxiety-relieving effect by increasing blood oxygen saturation and reducing autonomous arousal.
[0073] In addition, the above rosemary essential oil is an essential oil obtained by distilling the aerial part and is composed of 16 compounds, namely Cineole, Camhor, a-Pinene, Camphene, and a-Terpineol. A-Pinene may be involved in anxiety-relieving properties and may have the effect of improving memory and mood.
[0074] In addition, the above clary sage essential oil is obtained by distilling the entire aerial part of clary sage, and the compounds of Linalool, a-Terpineol, Geraniol, Geraniol Acetate, and Myrcene Acetate contained therein are involved in the antidepressant effect and can exhibit remarkable anxiolytic properties.
[0075] In addition, the above Roman chamomile essential oil is an oil distilled from the flower head of Roman chamomile, and its constituent compounds, Isobutyl Angelate, Isoamyl Angelate, and 2-Methylbutyl Isobutylrate, have a psychostimulant effect and can have anxiolytic and sedative effects.
[0076] In addition, the above peppermint essential oil is an essential oil obtained by steam distillation from the leaves of peppermint, and among the compositions consisting of 26 or more compounds, Menthol and Iso-Menthone are the majority, and these components can improve concentration and memory.
[0077] Meanwhile, the oxygen generating container (500) can be coupled to the filter sheet (100) to store the oxygen generating material (10) inside, and can be sealed by the cover member (300) to prevent oxygen from being generated before use. The oxygen generating container (500) can be configured such that the container body penetrates a cut area formed in a part of the filter sheet (100), and one end is completely sealed (closed), and the other end is bent in a flange shape to form a border portion and is open. The cover member can be coupled to the border portion of the container body so as to seal the open portion by isolating it from the outside. That is, the closed portion of the oxygen generating container (500) can be defined as facing outward opposite to the user's face, and the open portion can be defined as facing inward facing the user's face so as to supply oxygen to the user's respiratory system. Meanwhile, the container body can be fixed to the filter sheet (100) by the coupling frame (550). That is, the oxygen generating container (500) can be fixed to the filter sheet by connecting the container body and the connecting frame with a filter sheet interposed between a part of the container body and the connecting frame.
[0078] Meanwhile, the oxygen generating material (10) may include, for example, potassium peroxide (KO2) and calcium hydroxide (Ca(OH)2), and may be characterized in that the weight ratio of the potassium peroxide to the calcium hydroxide is in the range of 8:2 to 5:5. A reaction may occur to generate water (H2O) by carbon dioxide transmitted from the user's respiratory system or carbon dioxide transmitted from the surroundings by the calcium hydroxide, and the potassium peroxide may react with the generated water to generate oxygen (O2).
[0079] For example, the oxygen-generating composition of the present invention can generate oxygen according to sequential reactions such as the following reaction formulas (1) and (2). That is, as in the following reaction formula (1), calcium hydroxide (Ca(OH)2) can generate calcium carbonate (CaCO3) and water (H2O) by carbon dioxide (CO2) generated from the user's mouth or nose or introduced from the surroundings, and the water (H2O) generated by the reaction formula (1) can react with potassium peroxide (KO2) through the reaction of the following reaction formula (2) to generate products such as oxygen (O2), potassium hydroxide (KOH), and hydrogen peroxide (H2O2), thereby ultimately generating oxygen.
[0080] Reaction formula (1)
[0081] Ca(OH)2+ CO2→ CaCO3+ H2O
[0082]
[0083] Reaction formula (2)
[0084] 2KO2+ 2H2O → O2+ 2KOH + H2O2
[0085]
[0086] Meanwhile, by satisfying the weight ratio of the potassium peroxide to the calcium hydroxide in the range of 8:2 to 4:6, oxygen can be generated more quickly and more oxygen can be generated compared to the introduced carbon dioxide. Preferably, for example, the weight ratio of the potassium peroxide to the calcium hydroxide can be in the range of 8:2 to 5:5, in the range of 7:3 to 5:5, in the range of 7.5:2.5 to 5.5:4.5, or in the range of 7:3 to 6:4. Meanwhile, when the content of potassium peroxide is excessive, for example, when the weight ratio of the potassium peroxide to the calcium hydroxide exceeds 8:2, the moisture generated in the first reaction with the calcium hydroxide may react with the powdery compound to form a paste, which may cause a problem of delayed reaction.
[0087] Meanwhile, the oxygen-generating composition may be characterized by further including manganese dioxide (MnO2). By including the manganese dioxide, more oxygen can be generated. For example, when H2O2 is generated through the above reaction formula (2), additional oxygen and water can be generated through a reaction as shown in the following reaction formula (3), and the additionally generated water can again generate more oxygen through the process of the above reaction formula (2).
[0088]
[0089] Reaction formula (3)
[0090]
[0091]
[0092] For example, the manganese dioxide (MnO2) may be in a range of 5 to 20 parts by weight relative to 100 parts by weight of the potassium peroxide and the calcium hydroxide. In the above range, a sufficient amount of oxygen can be generated while oxygen can be generated more quickly.
[0093] Meanwhile, the oxygen-generating composition may be characterized by further comprising potassium nitrate (KNO3) or potassium chloride (KCl). In the process in which the oxygen-generating composition reacts with carbon dioxide and ultimately generates oxygen through the water produced thereby, a rapid exothermic reaction may occur, and ultimately, the temperature of the oxygen-generating composition may rise to a high temperature due to the high reaction temperature. In this case, the user may experience skin damage or respiratory damage due to the high temperature. However, by including potassium nitrate (KNO3) or potassium chloride (KCl) as described above, the heat generated by the reaction can be absorbed, and thereby the temperature of the oxygen-generating material can be prevented from rising during the process in which the oxygen-generating material reacts to generate oxygen, thereby allowing the user to use the oxygen-generating material more safely.
[0094] For example, the potassium nitrate or the potassium chloride may be present in an amount ranging from 100 to 240 parts by weight relative to 100 parts by weight of the potassium peroxide and the calcium hydroxide. Within the above range, it is possible to effectively control the exothermic reaction while ensuring a sufficient amount of oxygen generation.
[0095] In addition, the potassium nitrate or the potassium chloride may be included in a range of 3 to 5 times the weight ratio of the potassium peroxide, for example, the potassium nitrate or the potassium chloride may be included in a range of 3.5 to 4.5 times the weight ratio of the potassium peroxide. In the above range, the temperature increase due to the exothermic reaction when the oxygen generating material reacts can be very effectively prevented, while the amount of oxygen generated can be prevented from decreasing. That is, when the potassium nitrate or the potassium chloride is less than 3 times, the temperature increase control effect may be minimal, and when it exceeds 5 times, a paste phenomenon may occur frequently, which may reduce the amount of oxygen generated. Therefore, it is possible to generate a large amount of oxygen while effectively controlling the temperature in the above range.
[0096] Meanwhile, the oxygen-generating composition may be characterized by further comprising sodium bicarbonate (NaHCO3). The sodium bicarbonate allows the oxygen-generating composition to generate an excess of oxygen during the initial reaction, thereby enabling the immediate generation of an excess of oxygen in an emergency situation, and particularly, in a disaster situation such as a fire in which toxic gases spread, it can generate a large amount of oxygen more quickly. For example, the substances generated by the above reaction formulas (1) and (2) may be basic, and by adding the sodium bicarbonate, the basicity may be neutralized through an acid-base reaction, thereby promoting the reaction so that the reactions of the above reaction formulas (1) and (2) actively proceed. Ultimately, by removing the KOH compound generated by the reaction formula (2) through the acid-base reaction of sodium bicarbonate, the reaction may proceed more toward the product, thereby rapidly generating a large amount of oxygen.
[0097] The above sodium bicarbonate may be included in an amount of 20 to 40 parts by weight relative to 100 parts by weight of the potassium peroxide and the calcium hydroxide. In the above range, a sufficient amount of oxygen can be generated while allowing oxygen to be generated more quickly.
[0098] Meanwhile, the oxygen-generating composition may be characterized by further comprising silica (SiO2). During the process of generating oxygen by reacting the potassium peroxide and the calcium hydroxide, the resulting mixture may form lumps due to agglomeration, thereby reducing the amount of oxygen generated. However, by further comprising the silica, the agglomeration can be prevented, thereby ensuring a sufficient amount of oxygen generation. The silica may be included in an amount of 10 to 40 parts by weight, or in an amount of 10 to 30 parts by weight, based on 100 parts by weight of the potassium peroxide and the calcium hydroxide. Within the above range, a sufficient amount of oxygen generation can be secured while preventing agglomeration.
[0099] Meanwhile, the oxygen-generating material (10) may be stored inside a bag having micropores and positioned inside the oxygen-generating container (500). The oxygen-generating material is in the form of a mixed powder and may be stored inside the bag having micropores to prevent the oxygen-generating material from leaking out, and when oxygen is generated, the oxygen may be released to the outside (into the user's respiratory system) through the micropores. The bag may be placed inside the oxygen-generating container (500) and maintained in a sealed state by a cover member (300) while preventing it from leaking out to the outside by a barrier frame (300). When sealed by the cover member (300), no separate reaction occurs and the oxygen-generating material may remain in a powder state. If the cover member (300) is removed and carbon dioxide (from the user's breath or the surrounding air) is supplied from the outside and moisture (from moisture present in the user's breath or moisture present in small amounts in the surroundings) is supplied, a reaction of generating oxygen begins. The oxygen generated thereafter can pass through the pores of the pouch and provide oxygen to the user's respiratory system.
[0100] Meanwhile, the wearing strap (200) is connected to both ends of the filter sheet (100) and may include at least two first wearing straps (210) and second wearing straps (220) of different lengths. By including the first wearing straps (210) and second wearing straps (220) of different lengths, even users with different face sizes can easily use the mask. For example, a child with a small face can use a short wearing strap to wear the mask on his or her face, and an adult with a relatively large face can use a long wearing strap to wear the mask on his or her face. Therefore, in the event of an emergency, anyone, regardless of age or gender, can quickly and easily put on the mask to escape the emergency.
[0101] The first wearing strap (210) and the second wearing strap (220) may be characterized by being bonded to the same point on the filter sheet (100). By bonding them to the same point, the area in which the filter function is performed in the mask can be secured to the maximum extent. In addition, the first wearing strap (210) and the second wearing strap (220) may be characterized by being ultrasonically bonded to the filter sheet (100). By placing the first wearing strap (210) and the second wearing strap (220) at the same position and then bonding them ultrasonically at the same time, the bonding strength can be increased and the two wearing straps (200) can be joined to the filter sheet (100) in a simplified process. In addition, a more solid bonding strength can be secured by performing the ultrasonic bonding only once. When performing the ultrasonic bonding multiple times, a problem may occur in which the part that was bonded first is separated by the part that is bonded later. However, by performing the ultrasonic bonding simultaneously, such a problem can be prevented.
[0102] In addition, the first wearing strap (210) and the second wearing strap (220) may be formed of an elastic material, but the first wearing strap (210) may be shorter than the second wearing strap (220), and the first wearing strap (210) may have lower elasticity than the second wearing strap (220). That is, the first wearing strap (210) having a shorter length has a weaker restoring force to return to its original length when stretched compared to the second wearing strap (220), and thus, may be stretched longer with less force. Accordingly, when the first wearing strap (210) and the second wearing strap (220) are joined to the same point of the filter sheet (100), the force applied to the first wearing strap (210) and the second wearing strap (220) in the joining machine can be adjusted to a level that is almost equivalent to each other, thereby enabling the joining to be done at a more precise position.
[0103] To be more specific, in a mass production process of a continuous process, when the filter sheet (100) moves, the first wearing strap (210) and the second wearing strap (220) can be pulled to join at the same position of the filter sheet (100) starting from the same position by a mechanical device or configuration, thereby forming a joining. In this case, since the elasticity of the first wearing strap (210) is formed weakly due to the short length, the restoring force generated when the first wearing strap (210) and the second wearing strap (220) are stretched is formed weaker for the first wearing strap (210), and ultimately, the force applied to the mechanical device by the first wearing strap (210) and the second wearing strap (220) can be adjusted to an equivalent level. Therefore, it is possible to prevent an error from occurring in the position where the first wearing strap (210) and the second wearing strap (220) are joined due to different forces (elasticity, restoring force).
[0104] Meanwhile, it may be characterized by further including a first reinforcing strap (160) that is physically connected while penetrating the filter sheet (100) with the first wearing strap (210) and the second wearing strap (220) interposed between the filter sheet (100). The first wearing strap (210) and the second wearing strap (220) may be bonded to the filter sheet (100) by ultrasonic bonding for a mass production process, but if a strong force is applied to the wearing strap (100), a phenomenon of separation from the filter sheet (100) may occur. In addition, if the filter sheet (100) contains liquids such as various extracts in order for the mask to be used in a disaster situation such as a fire, the bonding strength of the wearing strap (200) may be further weakened. Accordingly, the first reinforcing strap (160) is physically coupled to the filter sheet (100) while penetrating the filter sheet (100) with the first wearing strap (210) and the second wearing strap (220) interposed between the filter sheet (100), thereby very effectively preventing the wearing strap (200) from being separated from the filter sheet (100).
[0105] Meanwhile, the filter sheet (100) may be characterized in that the first side (110) and the second side (120) facing each other are joined by ultrasonic bonding, and further include a second reinforcing strap (170) that repeatedly passes over the first side (110) and the second side (120) and is physically joined at the end where the first side (110) and the second side (120) face each other. The filter sheet (100) may be configured such that the first side (110) and the second side (120) having symmetrical shapes are connected at the top (or bottom), and the central curved portion may be joined to each other to form a three-dimensional shape. The central portion may be joined by ultrasonic welding. Therefore, the ends of the parts that are not connected and joined by ultrasonic welding can be separated with a relatively small force. Accordingly, the second reinforcing strap (170) repeatedly passes through the first surface (110) and the second surface (120) to physically connect them, thereby preventing the first surface (110) and the second surface (120) from being easily separated. In particular, when the mask of the present invention is used for fire evacuation and the filter sheet (100) contains a liquid extract, separation of the first surface (110) and the second surface (120) may occur more easily, and thus separation of the filter sheet (100) can be more effectively prevented by the second reinforcing strap (170).
[0106] FIG. 4 is a drawing showing a mask according to another embodiment of the present invention as viewed from the direction in which the user wears the mask.
[0107] Referring to FIG. 4, the oxygen generating container (500) may be characterized by being coupled to both the first side (110) and the second side (120). That is, the masks of FIGS. 1 to 3 have the oxygen generating container coupled to only one side of the mask, but as shown in FIG. 4, the oxygen generating containers may be coupled to both sides of the mask to provide more oxygen. The user may appropriately adjust the coupling of the oxygen generating container to one or both sides of the mask as needed.
[0108] FIG. 5 is an exploded perspective view schematically showing how each component of an oxygen generating container is coupled to a filter sheet in a mask according to an embodiment of the present invention, and FIG. 6 is a drawing showing a state of use of a mask according to an embodiment of the present invention. In addition, FIG. 7 is a drawing schematically showing a relationship in which a cover member is coupled to a container body of an oxygen generating container in a mask according to an embodiment of the present invention, and FIG. 8 is a drawing showing a barrier frame of an oxygen generating container in a mask according to an embodiment of the present invention, and FIG. 9 is a drawing showing an operating unit coupled to a cover member in a mask according to an embodiment of the present invention.
[0109] Referring to FIGS. 5 to 9, the oxygen generating container of the present invention will be described in more detail. The oxygen generating container (500) may include a container body (510) that is coupled to the filter sheet (100), has one side open and the other side closed to form a receiving space (C) on the inside, and includes a rim portion (520) formed by being bent in a flange shape, and a step (530) formed by being bent in the inner receiving space (C), a barrier frame (300) that includes a plurality of air passages (310) and is coupled to the container body (510) by being accommodated on the inside of the container body (510) and seated on the step (530), and a cover member (400) that is coupled to the upper end of the rim portion (520) of the container body (510) to seal the oxygen generating material (10) on the inside. In addition, a joining frame (550) may be further included to join the container body (510) to the filter sheet (100) by interposing the filter sheet (100) on the rear side of the edge (520) of the container body (510).
[0110] The closed other side of the above container body (510) is inserted into an empty space formed on the inside of the filter sheet (100), and a joining frame (550) is arranged on the other side of the filter sheet (100), so that the container body (510) can be joined to the filter sheet (100) interposed in the middle by the joining of the container body (510) and the joining frame (550). In addition, a bag (bag) containing an oxygen-generating substance is arranged in the space on the inside of the container body (510), and a barrier frame (300) is placed and joined to the step (530) on the upper part thereof to prevent the oxygen-generating substance from leaking out, while allowing gas or moisture to move. A cover member (400) is attached to the upper part of the container body (510) to seal the inside of the container body (510), and as shown in FIG. 6, when the cover member (400) is removed and moisture and carbon dioxide are introduced as an oxygen generating material, a reaction that generates oxygen can begin.
[0111] In other words, the container body (510) may be formed in a flange shape with one side open and the other side closed to form a receiving space (C) on the inside, and may be formed with a rim (520) and may be coupled to a filter sheet (100). The container body (510) may be provided with a receiving space (C) on the inside to store an oxygen generating substance, and may be coupled to a filter sheet (100) so that when a user removes the cover member (400), carbon dioxide and moisture, etc. may be supplied to the oxygen generating substance (10) received through the open side to cause a reaction and generate oxygen. Therefore, oxygen can be supplied to the user's respiratory system and the user's survival time can be increased.
[0112] The container body (510) can be configured such that the other side, i.e., the lower side, is closed and one side, i.e., the upper side, is open, so that oxygen can only proceed in the direction of the user's respiratory tract and external toxic gases can be prevented from proceeding to the user's respiratory tract. In other words, the closed part of the other side of the container body (510) and the outer side of the filter sheet (100) form one closed side on the outer side based on the user's face, and the supply of moisture or carbon dioxide to the oxygen generating substance and the supply of oxygen through a reaction can be performed on the inner side of the filter sheet (100) facing the user.
[0113] The above-described joining frame (550) can join the container body (510) to the filter sheet (100) by interposing the filter sheet (100) on the rear side of the edge portion (520) of the container body (510). That is, the joining frame (550) can perform the function of fixing the container body (510) to the filter sheet by joining the filter sheet (100) on the other side (rear side) of the edge portion (520) constituting the open upper surface of the container body (510). Meanwhile, the joining of the joining frame (550) and the container body (510) with the filter sheet (100) interposed therebetween can be performed by ultrasonic welding, but is not limited thereto, and can be performed by a thermal welding method. The oxygen generating container (500) can be maintained in a state of being joined to the filter sheet (100) by the joining frame (550).
[0114] Meanwhile, the barrier frame (300) may be formed with a plurality of air passages (310) and accommodated inside the container body (510) and coupled to the container body (510). The barrier frame (300) may be mounted on a step (530) in the empty space (C) inside the container body (510) and may be coupled or joined by the arranged components, for example, may be coupled by a protruding / concave joint or may be adhered by a separate adhesive layer. However, in order to prevent the generation of toxic gases due to adhesive substances in a high-temperature environment such as a fire, a joint by a protruding / concave joint or a fitting joint by a physical configuration may be preferable. This will be described in more detail later.
[0115] The above barrier frame (300) can prevent (block) the bag (bag) containing the oxygen-generating substance within the container body (510) from leaking out to the outside. The air passage (310) formed by a plurality of empty spaces of the barrier frame (300) can serve as a passage function to allow oxygen to move to the outside of the container body (510) while preventing the oxygen-generating substance (10) from escaping, thereby serving as an oxygen movement passage. That is, the barrier frame (300) can accommodate a relatively large oxygen-generating substance (10) in the inner empty space (C) of the container body (510) and prevent it from escaping to the outside while allowing gas to pass through, thereby allowing gases such as carbon dioxide, moisture, and oxygen to easily flow in and out.
[0116] Meanwhile, the cover member (400) can be coupled to the upper end of the edge portion (520) of the container body (510) to seal the oxygen generating material (10) inside. In addition, the cover member (400) can include a protruding area (430) that protrudes more than the edge portion (530) of the container body (510). That is, the cover member (400) can include a coupling area (420) coupled along the surface of the edge portion (520) of the container body (510), an inner area (410) that is present on the inside of the coupling area (420) and faces the empty space and barrier frame on the inside of the container body (510), and a protruding area (430) that is present on the outside of the coupling area (420) but protrudes in a specific direction. The joining area (420) of the cover member (400) can be joined to the upper end of the edge portion (520) of the container body (510) and can form a closed curve with a shape corresponding to the surface shape of the edge portion (520) so as to completely seal the oxygen generating material (10) inside. Accordingly, the empty space (C) inside the container body (510) can be completely sealed, so that excellent airtightness can be maintained.
[0117] The protruding area (430) of the cover member is formed to protrude outward from the joining area (420) but not outward from the area formed by the filter sheet (100) so that the user can easily remove the cover member (400) by hand when removing the cover member (400) from the container body (510) to use the mask (i.e., when a situation arises where oxygen must be generated). Accordingly, when the mask is not being used and is stored, the protruding area (430) of the cover member (400) exists only on the inside of the filter sheet (100), thereby preventing the cover member (400) from being unintentionally separated. If the protruding area (430) of the cover member (400) is formed wider (larger, further) than the area where the filter sheet (100) is formed and is exposed to the outside of the filter sheet (100), force may be applied to the cover member from the outside of the filter sheet of the mask, and the cover member may be undesirably separated or a leak may occur in the sealed area, thereby reducing the airtightness. Therefore, the protruding area (430) of the cover member (400) may be formed only in the inner area of the filter sheet (100), thereby preventing the airtightness from being reduced.
[0118] Meanwhile, the cover member (100) may have a multilayer structure composed of one or a mixed layer of polypropylene (PP), ethylene vinyl alcohol (EVOH), polycarbonate (PC), polyvinyl chloride (PVC), polyethylene terephthalate (PET), and aluminum foil to maintain airtightness and effectively block moisture. Among these, it may be preferable that the surface facing the inner empty space (C) of the container body (510) be composed of a layer formed of a material including aluminum foil to effectively block moisture while preventing it from being easily damaged.
[0119] Meanwhile, the cover member (400) may further include an operating part (600) coupled to the protruding area (430). In addition, the protruding area of the cover member (100) to which the operating part (600) is coupled may be characterized in that it is arranged in a downward direction based on the user's face. The operating part (600) may be formed of a hard material molded from various resin materials, and may enable the user to grasp and detach the cover member (400) more easily and quickly. The operating part (600) may be formed of a polymer resin material such as, for example, a polypropylene (PP) resin material, a polycarbonate (PC) resin material, or a mixture thereof, but is not particularly limited thereto.
[0120] It is possible to make it possible to understand that the cover member (400) is configured to be easily detachable by the user in an emergency disaster situation or a situation that requires urgent use by the operating unit (600) due to the material formed firmly, unlike other soft materials, and to detach the cover member (400) that is firmly connected to the edge portion (520) of the container body (510) by grasping the relevant portion and applying force to detach it, thereby making it easier to detach it. The operating unit (600) may have Braille formed on it, or a separate mark (letters, etc.) engraved or embossed so that it can be confirmed that it is a position where the cover can be detached even in a situation where it is not visually visible, and this may be formed during the process of injecting the operating unit (600).
[0121] The above operating unit (600) may be positioned downward relative to the user's face to allow for easier removal of the cover member (400). The shape of a human face generally has a narrower surface area toward the chin compared to the cheeks or the cheek area. Therefore, if the operating unit (600) is positioned downward relative to the user's face, a large space is created for the user to manipulate the operating unit (600) with their hands, allowing for easier removal of the cover member (600).
[0122] The above-described operating part (600) may include a first plate (610) disposed on one surface of the cover member (400) and including a penetrating groove (630), a second plate (620) disposed on the other surface of the cover member and protruding, and including a connecting pillar (640) penetrating the cover member and connected to the groove (630), and a cavity (650) formed as an empty space at a connecting portion of the first plate (610) and the second plate (620), and the first plate (610) and the second plate (620) may be formed integrally and connected to the cover member in a folded state at one end.
[0123] Specifically, the operating part (600) may include a first plate (610) disposed on one surface of the cover member (400) and including a groove (630), and a second plate (620) disposed on the other surface of the cover member and including a protruding connecting pillar (640), wherein the connecting pillar (640) may be characterized in that it penetrates the cover member (100) and is connected to the groove (630). The above-described operating unit (600) has a groove (630) formed on the first plate (610), and a coupling pillar (640) facing the groove (630) is formed on the second plate (620) facing the first plate (610), so that the groove (630) and the coupling pillar (640) are coupled to each other, thereby allowing the first plate (610) and the second plate (620) to be coupled to the cover member (400). Accordingly, the cover member (400) can be more easily removed from the container body (510) by the operation of the operating unit (600).
[0124] The first plate (610) and the second plate (620) of the operating part (600) can be formed integrally and joined to the cover member (400) in a folded state at one end. The operating part (600) can be formed integrally by injection molding, and the position where the first plate (610) and the second plate (620) are connected can be folded so that the first plate (610) and the second plate (620) face each other and the groove (630) and the joining pillar (640) face each other, so that the operating part can be easily joined and fixed to the cover member (400). In addition, when the cover member (400) is separated from the operating member (600) by the combination of the home part (630) and the connecting pillar (640), the operating member (600) can be prevented from easily coming off from the cover member (400) due to an external force.
[0125] The cavity (650) is formed at a location where the first plate (610) and the second plate (620) are connected, and may be formed at a location where the first plate (610) and the second plate (620) are folded, and may be formed as an empty space. As shown in the drawing, the locations where the first plate (610) and the second plate (620) are connected may be formed at both ends, and the central portion may be formed as an empty space. Accordingly, by combining the integrally formed operating part with the cover member, the mask can be manufactured in a simplified process while minimizing the weight of the operating part, thereby minimizing the weight of the mask.
[0126] FIG. 10 shows a cross-section taken along line A-A' in FIG. 7 according to one embodiment.
[0127] Referring back to FIGS. 7 and 10, the barrier frame (300) may be characterized in that it is mounted and coupled to a step (530) formed on the inside of the container body (510). In addition, it may be coupled in various ways, such as by using a separate bonding member such as an adhesive or a physical bonding such as a concave-convex bonding. Meanwhile, the height (P2) from the upper surface of the step (530) of the container body (510) to the upper end of the rim (520) of the container body (510) may be characterized in that it is equal to or higher than the height (P1) from the upper surface of the step (530) of the container body (510) to the upper end of the barrier frame (300). In other words, the height (P2) from the upper surface of the step (530) of the container body (510) to the upper end of the rim (520) of the container body (510) may be the same as the height (P1) from the upper surface of the step (530) of the container body (510) to the upper end of the barrier frame (300), or the height (P2) from the upper surface of the step (530) of the container body (510) to the upper end of the rim (520) of the container body (510) may be higher than the height (P1) from the upper surface of the step (530) of the container body (510) to the upper end of the barrier frame (300).
[0128] That is, the upper end of the barrier frame (300) can be formed at a position that is the same as or lower than the horizontal plane on which the cover member (400) is coupled to the rim portion (520) of the container body (510). When the cover member (400) is coupled to the rim portion (520) of the container body (510), the upper end of the barrier frame (300) can be in contact with the lower end of the cover member (400) but can be configured at the same height. Alternatively, when the cover member (400) is coupled to the rim portion (520) of the container body (510), the upper end of the barrier frame (300) can be prevented from being in contact with the lower end of the cover member (400), thereby preventing the barrier frame (300) from affecting the cover member (400) and reducing the airtightness. In other words, the cover member (400) is prevented from coming into contact with any part other than the rim portion (520) where it is coupled to the container body (510), thereby increasing the bonding strength between the cover member (400) and the rim portion (520) and preventing the bonding strength from being weakened by other parts. Even if the cover member (400) comes into contact with the barrier frame (300), the lower surface of the cover member (400) and the upper surface of the barrier frame (300) are substantially arranged on the same horizontal plane, thereby preventing a decrease in the airtightness of the cover member (400).
[0129] In the past, the barrier frame was placed on the upper edge of the container body, and a sealing member was formed on the upper part of the barrier frame to seal the container body and the upper part of the barrier frame to ensure airtightness, and then the space between the barrier frame and the sealing member had to be sealed again to ensure airtightness. In this case, the problem of airtightness deteriorating in other locations could occur during the two sealing processes. In particular, in order to increase airtightness, prevent damage to the sealing member, and ensure rapid production, an ultrasonic welding method is mainly used, but in this process, a problem of airtightness deteriorating in the part that was processed first could occur. Therefore, as in the present invention, the barrier frame (300) is placed on a step (530) on the inside of the container body (510), and the height of the barrier frame (300) is made equal to or lower than the height of the cover member (400), thereby preventing the deterioration of airtightness. That is, the airtightness can be increased by making the upper surface of the barrier frame (300) in contact with the lower surface of the cover member (400) but arranged on the same horizontal plane, or by making the upper surface of the barrier frame (300) not in contact with the lower surface of the cover member (400) (by substantially making the barrier frame and the cover member not in contact). That is, only the upper surface edge portion (520) of the container body (510) is made in contact with the cover member (400), and the cover member (400) is coupled and sealed only through this portion, and the impact on the cover member (400) at other locations is minimized, thereby maximizing the airtightness.
[0130] Meanwhile, in order to prevent a decrease in airtightness, the barrier frame (300) may be preferably positioned spaced apart from the cover member (400) on the inside of the container body (510). Alternatively, the cover member (400) may be coupled (joined) only to the edge portion (520) of the container body (510), and the barrier frame (300) may not be coupled (joined) to the cover member (400). That is, the barrier frame (300) may partially contact the cover member (400), but is not in a coupled state, so that when the cover member (400) is separated and removed, the barrier frame (300) may not be affected in any way.
[0131] Meanwhile, FIG. 11 shows a drawing showing a cross-section taken along line A-A' in FIG. 7 according to another embodiment. Also, FIG. 12 shows a drawing showing a cross-section taken along line A-A' in FIG. 7 according to another embodiment.
[0132] Referring to FIGS. 11 and 12, the barrier frame (300) may further include a hole (321) or a protruding projection (322), and the container body (510) may further include a protrusion (540) or a hole (545) that can be combined with the hole (321) or the protruding projection (322) of the barrier frame (300). This may be formed in various directions, such as being formed vertically or horizontally. The oxygen generating container (501, 502) can be configured so that the barrier frame (301, 302) is not separated from the container body (510) by combining the hole (321) or the protruding projection (322) of the barrier frame (300) with the projection (540) or the hole (545) formed on the inside of the container body (510) in a recessed and protruding manner. Accordingly, even when the user removes and uses the cover member (400), the barrier frame can be prevented from being separated and the oxygen generating material inside from leaking out. However, the combination of the barrier frame and the container body is not limited to the recessed and protruding combination, and the combination can be performed in various ways, such as by bonding using a separate adhesive material.
[0133] Meanwhile, the present invention provides a method for manufacturing the above-described mask, and below, a method for manufacturing a mask according to various embodiments of the present invention will be described with reference to the various drawings described above. The mask manufacturing method of the present invention can be applied to all of the various embodiments of the mask described above, and any redundant descriptions will be omitted. However, even if the redundant descriptions are omitted, each component can be applied to the mask manufacturing method of the present invention.
[0134] A method for manufacturing a mask according to one embodiment of the present invention comprises the steps of: preparing a filter sheet (100); placing the rear side of the frame (520) of a container body (510) including a frame (520) formed along the outer periphery of the upper surface by being folded in a flange shape to form a receiving space on the inside and a step (530) formed by being folded in the inner receiving space, on one side of the filter sheet (100); placing a joining frame (550) so as to face the rear side of the frame (520) of the container body (510) and joining it with the filter sheet (100) interposed therebetween; placing a bag (10) containing an oxygen generating substance in the receiving space (C) of the container body (510); placing a barrier frame (300) including a plurality of air passages (310) on the inside of the container body (510), wherein: It includes a step of arranging and combining on a step (530), a sealing step of combining a cover member (400) to the upper end of the edge portion (520) of the container body (510), and a step of joining a wearing strap (200) including two or more first wearing straps (210) and second wearing straps (220) of different lengths to both ends of the filter sheet (100).
[0135] In addition, the step of joining the container body (510) may be characterized by joining the other surface of the edge portion (520) of the container body (510) and the joining frame (550) through ultrasonic fusing or thermal fusing while interposing the filter sheet (100). In addition, the sealing step may be characterized by joining the upper end of the edge portion (520) of the container body (510) and the cover member (400) through ultrasonic fusing.
[0136] In addition, when the cover member (400) is coupled to the container body (510) by the sealing step, the barrier frame (300) may be characterized in that it does not come into contact with the cover member (400), and the upper end of the rim portion (520) of the container body (510) may be characterized in that it is higher than the height of the barrier frame (300). Accordingly, the barrier frame (300) may not affect the sealing between the rim portion (520) of the container body (510) and the cover member (400), thereby increasing airtightness. The conventional step of performing multiple times to maintain airtightness may be limited to only one time between the rim portion (520) of the container body (510) and the cover member (400), thereby increasing airtightness and simplifying the process.
[0137] Meanwhile, the container body joining step may join the rear surface of the rim of the container body and the joining frame by ultrasonic welding while interposing the filter sheet, and the sealing step may join the upper surface of the rim of the container body and the cover member (400) to the container body (510) by ultrasonic welding. In the sealing step, the barrier frame (300) is seated on a step (530) formed in the inner empty space (C) of the container body (510), and is formed at a low height so as not to come into contact with the cover member (400), thereby not affecting the sealing of the cover member (300), thereby increasing the airtightness of the oxygen generating container (500).
[0138] Meanwhile, the barrier frame (300) may be joined to the container body (510) by a protruding and protruding joint or by a joint material, and may be joined to the container body (510) in various other ways. The form and various joint forms of the joint between the container body (5 10) and the barrier frame (300) have already been sufficiently described above, and thus, a redundant description will be omitted.
[0139] Meanwhile, the step of joining the wearing straps may be characterized by joining the first wearing strap (210) and the second wearing strap (220) simultaneously, and the first wearing strap (210) and the second wearing strap (220) may be formed of an elastic material, but the first wearing strap (210) may be shorter than the second wearing strap (220), and the first wearing strap (210) may have lower elasticity than the second wearing strap (220). Accordingly, even when a plurality of wearing straps (210, 220) of different lengths are joined to the same position of the filter sheet (100), an equal force may be applied to the mechanical device handling the first wearing strap (210) and the second wearing strap (220), thereby enabling more precise joining (or bonding).
[0140] Meanwhile, the first wearing strap (210) and the second wearing strap (220) may be characterized in that they are joined at the same point on the filter sheet (100). In addition, the first reinforcing strap (160) may be further included that is physically connected by penetrating the filter sheet (220) with the first wearing strap (210) and the second wearing strap (220) interposed between the filter sheet (100). Meanwhile, since this has already been described in the description of the mask, a redundant description thereof will be omitted.
[0141] Meanwhile, the first wearing strap (210) and the second wearing strap (220) may be formed of an elastic material, but the first wearing strap (210) may be shorter than the second wearing strap (220), and the first wearing strap (210) may have lower elasticity than the second wearing strap (220). The difference in length and elasticity between the first wearing strap (210) and the second wearing strap (220) have already been described in the description of the mask, and therefore, a duplicate description will be omitted.
[0142] In addition, the filter sheet (100) may be characterized in that the first side (110) and the second side (120) facing each other are joined by ultrasonic bonding, and further include a second reinforcing strap (170) at the end where the first side (110) and the second side (120) face each other, which repeatedly passes over the first side (110) and the second side (120) and is physically joined. The second reinforcing strap (170) has already been described in the description of the mask, and therefore, a redundant description thereof will be omitted.
[0143] It may be characterized by further including a liquid natural extract contained in the above filter sheet (100). The types of ingredients that may be contained in the above natural extract and the functions and roles of each ingredient have already been described while describing the above mask, so any redundant description will be omitted.
[0144] The above oxygen generating container (500) may be characterized by being connected to both the first surface (110) and the second surface (120). This allows for a greater supply of oxygen to the user, and as this has already been described in relation to the mask, a redundant description thereof will be omitted.
[0145] The oxygen generating container (500) may include a container body (510) having one side open and the other side closed to form a receiving space inside and a rim formed in a flange shape, a joining frame for joining the container body (510) to the filter sheet (100) by interposing the filter sheet (100) on the rear side of the rim (520) of the container body (510), a barrier frame (300) having an air passage (310) formed of a plurality of empty spaces and received inside the container body (510) and joined to the container body (510), and a cover member (400) joined to the upper end of the rim (520) of the container body (510) to seal the oxygen generating material (10) inside, wherein the barrier frame (300) is disposed spaced apart from the cover member (400) on the inside of the container body (510).
[0146] In addition, the cover member (400) may include a protruding area (430) that protrudes more than the edge (520) of the container body (510), and may further include an operating part (600) coupled to the protruding area (430) of the cover member (400), and the protruding area (430) to which the operating part (600) of the cover member (400) is coupled may be characterized in that it is positioned in a downward direction based on the user's face.
[0147] In addition, the barrier frame (300) is characterized in that it is mounted and coupled to a step (530) formed on the inside of the container body (510), and the height (P1) from the step (530) of the container body to the top of the rim (520) of the container body (510) is characterized in that it is equal to or longer than the height (P2) from the step (530) of the container body (510) to the top of the barrier frame (300).
[0148] In addition, the operating part (600) may include a first plate (610) disposed on one surface of the cover member (400) and including a groove (630), and a second plate (620) disposed on the other surface of the cover member (400) and including a protruding coupling pillar (640), wherein the coupling pillar (640) penetrates the cover member (400) and is coupled to the groove (630), and the first plate (610) and the second plate (620) may be formed integrally and coupled to the cover member (400) in a folded state at one end.
[0149] The specific embodiments of the above oxygen generating container and the form of various embodiments that can be modified, the specific forms and various embodiments of each component, the cover member and the barrier frame, and the operating part have already been described while describing the above mask, so a detailed description of overlapping matters will be omitted.
