Abstract

The present application relates to respiratory masks that tightly cover the mouth and nose together. The mask is made up of at least two medical tissue layers and can be manufactured with N95 technology. The mask is characterized by the presence of a respiratory element having a unique cover (cap) containing a tablet impregnated with a medical or perfumed substance for inhalation by the user. The tablet closely covers the periphery of the cap of the breathing member from the inside and is connected to the cap. The cap may have an opening (hole or window) on the surface for air to enter the mask through the tablet, and the cap may not have an opening to increase the concentration of inhalation and prevent any leakage of air through the respiratory cap.

Description

Respiratory mask with replaceable odorous or medical cap

Technical Field

The application relates to a respiratory mask capable of covering the mouth and nose together, the mask being made up of two or more medical tissue layers. These layers of medical tissue shield most viruses, bacteria, germs and dust. Medical tissue layers may also be manufactured with N95 mask technology. The outer layer of the mask is liquid impermeable and the inner layer of the mask absorbs liquid towards the user. The mask is provided with a cord that is connected to the mask and can be tied behind the wearer's head, or two rubber bands on either side that can be rotated behind the wearer's ears, or rubber bands that can be behind the wearer's head. A flexible metal nose bridge is also provided. When the nose bridge is pressed against the sides of the nose by two fingers, the mask is pulled taut around the nose, thereby reducing air leakage.

The arrangement of the respiratory component is a particular feature of the mask described herein. The respiratory has a lid (cap) that is removed or secured in a rotational fashion similar to a water bottle cap. The interior of the cap of the respiratory element contains a respiratory tablet impregnated with a medical or fragrance substance for inhalation. The tablets may be made of cotton, fabric, special paper or the like. The cap of the respiratory component may not contain a respiratory tablet if the user does not need to be scented or medical substances.

Background

One of the closest techniques is described in US patent application No. 2005/0081856. It comprises a mouth and nose mask provided with two rubber bands on both sides, allowing the mask to be attached to the wearer's face by placing the rubber bands behind the wearer's ears. The mask features a flexible nose bridge that bridges to cinch the mask to the nose. On both sides of the nose bridge are provided flexible capsules containing a flavoured substance, which can be released by squeezing the capsule so that the flavoured liquid in the capsule flows out to the absorption tissue behind the capsule. One disadvantage of this type of mask is that any mechanical pressure present on the flavored capsules can rupture the capsules prior to donning the mask, which is common in handling and shipping. Thus, the scented material is expelled early before donning the mask, and the scented liquid material may flow onto the mask to wet the mask. This can lead to allergies in people allergic to this liquid. The mask cannot stop inhalation of the scented material and inhalation continues without stopping until the mask is disposed of. In the present application, the respiratory component has a cap containing a tablet impregnated with a medical or flavored substance. The cap may be replaced or disposed of at any time. The present application differs from the prior art in that it makes it possible to carry the mask itself with it any medical or fragrance-carrying substance, unlike what has been described in the prior art which comprises a fixed fragrance-carrying material that can only be replaced by replacing the mask itself. Moreover, the present application can be manufactured with N95 mask technology to filter bacteria and viruses.

In the prior art of US patent application No.2006/0107959, there is described the fusion of the mask described in the prior art with capsules in the middle of the mask, in front of the user's mouth and nose, which are easily ruptured to release a flavoured substance. The pouch in which the capsule can be secured is glued to the mask. The glue may contain substances that are not suitable for inhalation. In addition, the liquid material flowing from the capsule may flow onto the mask and contact the user's face. This can lead to allergies. In addition, the capsule may be broken under any mechanical pressure during transport and storage, thereby releasing the scented material prior to donning the mask. In the present application, a medical or flavored substance is contained within a tablet inside the cap of a respiratory device. The lid containing the tablets is held in a special enclosure (package) that is not connected to the mask. The package is opened just prior to use and then the cap holding the medical or perfumed tablet impregnated therein is secured to the neck of the wearer. Because of the barrier (mesh) between the tablet and the user's face, the tablet containing the medical or flavoured substance does not contact the user's face. The prior art scented material is also fixed into the mask and cannot be replaced unless the mask itself is replaced with each other. In the present application, different medical or fragrance materials can be used with the same mask without the need to replace the mask itself. The present application can also be manufactured with N95 mask technology to filter bacteria and viruses.

Respiratory masks with folds are described in the prior art of US patent No. 10486001. When the mask is donned, the fold is pulled away from the top and bottom to open the fold. Between the folds is a scented body. When the folder is opened, the cover is removed from the scented material, thereby diffusing the scent. The body carrying the scented material is prone to evaporation from the exterior of the mask rather than inhalation by the wearer of the mask. Unlike the description of the present application, the fragrance of the mask cannot be altered. The present application can also be manufactured with N95 mask technology to filter bacteria and viruses.

In the prior art of US patent No.5538013, a mouth-nose mask provided with a fragrance-bearing fabric material independent of the mask is described. The scented material may be attached to the mask from the inside, in front of the nose and mouth, in three different ways described by the present application: by internally securing the fabric containing the scented material to the mask, or by a perforated base to which the scented material is secured with an adhesive, or by a pouch containing tissue into which the scented material is inserted. The pouch is perforated to allow air and scented material to pass therethrough. The difference of the present application is that the sachets, carriers and flavoured tablets mentioned in the previous art are fixed using an adhesive (glue) or Velcro. The mounting of Velcro may require glue that can be inhaled by the user and may have a dangerous health effect. The present application provides advantages over the prior art in that: a medical or scented respiratory element is positioned to control the passage of air through its cover. A breathing member with a perforated cap allows air to pass through the tablet and if the cap is not perforated, air will not pass through it. In the prior art, the user must inhale the total amount of the scented material, even though the concentration and amount of the scented material is not appropriate for the user, in the present application the respiratory cap may or may not contain a medicinal or scented material tablet. Moreover, the respiratory cap containing the scented or medical material may or may not be perforated as described above. A perforated cover provided with holes on its outer surface allows air to pass through the tablet containing inhaled substance, thereby reducing the flow of exhaust gas to the outside of the mask. The present application can also be manufactured with N95 mask technology to filter bacteria and viruses.

In the prior art of US patent No.9629401, there is described an oronasal mask in which a further mask containing a flavoured or medical substance is mounted over the mask. The medical or scented mask is installed, removed, and covers approximately the size of the original mask. Such large size add-on masks consume large amounts of medical or scented substances. This is a waste of material. As there is no external protection against the dispersion of medical or scented substances into the external environment. In addition, the original mask adjacent the mouth and nose may absorb a significant amount of medical substances before contacting the user. In the present application, the absorbent member is partially expanded from the interior facing the user and a cover on the absorbent member prevents evaporation of the medical or fragrance-bearing substance to the outside environment (if the cap is not perforated) or limits evaporation (if the cap is perforated). The present application can also be manufactured with N95 mask technology to filter bacteria and viruses.

U.S. patent No.5243708 discloses a nose-only mask in which the bottom attachment for the wearer is held in the mouth. The mask contains a fragrance-bearing substance in the form of circumferential and transverse lines intersecting at the front of the nose. Each line contains a higher concentration of the scented material and the mask includes means operable to produce sound. The mask is often used when changing diapers and the sound is made to distract the child. The scented material serves to avoid inhalation of unpleasant odors during diaper changing. This prior art differs from the present application in that the technology is only used on the nose and the scented material is incorporated into the mask. The mask cannot be used without the scented material. Nor can the scented material be replaced with another material for the same mask. Moreover, this technique does not cover the mouth. These challenges do not exist with the present application. The present application can also be manufactured with N95 mask technology to filter bacteria and viruses.

One of the prior art is U.S. patent application No. 2003/0127202, which describes a medical mask for hospital patients. A tube for supplying medical gas is connected to the mask. The mask is characterized by a graphic shape containing vaporizable fragrance-bearing substances, and a medical gas is supplied to the wearer of the mask. Because of the need to contact a medical gas supply connected to the mask, this type of mask requires the wearer to remain in a position that does not allow people to move around on the road or walk around a studio or home or other location. The scented material in the mask is also fixed and cannot be removed or replaced unless the mask itself is replaced. These challenges do not exist with the present application. The present application can also be manufactured with N95 mask technology to filter bacteria and viruses.

In the prior art, US patent application No.2017/0021063 discloses a protective mask, the undesirable odors being fixed to known medical masks. The mask includes five layers, an outermost first layer distal from the mask securing the eyebrows, and second and third layers with ground coffee particles therebetween. Between the third and fourth layers there are activated carbon and sodium bicarbonate particles. The fifth layer has an adhesive adhered to the outer layer to attach the mask layer to the medical mask. In the present application, the ground coffee particles are used to absorb undesirable odors and provide a comfortable taste to the mask wearer. The document also mentions pellets with aromatic oil as a replacement for coffee, but this requires a large area of freshener surface. In addition, the fragrance is immobilized in a cover layer for the mask. Moreover, the presence of activated carbon and sodium bicarbonate can lead to the absorption of the flavoured substances. Also, the technique differs from the present application in that the medical or scented material cannot be replaced without replacing the mask itself. The present application can also be manufactured with N95 mask technology to filter bacteria and viruses.

Another prior art case is us patent application No.2012/0144556, which describes a mask for eyes and forehead and does not cover the nose and mouth. A pouch containing a cooling gel is provided which cools the forehead and eyes. The mask carries means for securing the package with the fragrance material inside. The package is provided with a door for controlling the width of the flavour release slot for controlling the amount of flavourant released from the package. Notably, the principle of the prior art fragrance material is that the face is released to the outside, i.e. to the environment surrounding the wearer of the mask. In the present application, the mask covers and protects the mouth and nose. The respiratory component is an essential part of the mask of the present application and medical or scented substances are transported inside the mask towards the surface of the wearer of the mask and not to the external environment. The present application can also be manufactured with N95 mask technology to filter bacteria and viruses.

One of the closest prior art is patent application No.120410582, filed to the sandy intellectual property office, which describes a respiratory mask with a respiratory element containing a tablet impregnated with a scented or medical substance. The cap of the respiratory has a side opening (slot) in the present application that matches in size with the opening on the neck of the respiratory. When the opening in the cap coincides with the opening in the neck, air passes through the breathing member; when the opening in the cap does not coincide with the opening in the neck, air does not pass through the breathing member. In the present application, the user must remove the tablet from the package and hold it by hand and place it inside the breathing member. This can cause bacterial and viral contamination of the tablets. Because the user's head is continually moving, for example while walking, the mechanism that coincides the side opening on the cap with the opening on the neck of the wearer may have difficulty maintaining the desired fit. The present application overcomes this difficulty by providing a cover that is not easily removable (the cover rotates securely on the neck of the wearer, i.e., the cover remains stationary when mounted on the respiratory component). At the same time, the present application does not provide openings in both the sides and neck of the respiratory, so that movement of the cap of the present application (if any) is not important to the mechanism by which the respiratory operates. The problem of touching the scented or medical tablet by hand is also overcome by connecting the scented tablet internally to the respiratory cap. The cap containing the tablets in a special package allows the user to hold the cap from the outside without touching the tablets from the inside. In the present application, two types of covers are designed, one type of cover being provided with holes (windows) of different shapes on its outer surface, so as to allow air to pass through the tablet to the user; another type of cap is not provided with a window on its outer surface so that volatile substances in the tablet are slowly discharged from the tablet into the interior by inhalation, without air passing through the breathing member. This will reduce evaporation of the tablet contents to the outside and also protect the user from inhalation of harmful bacteria by breathing.

Disclosure of Invention

The present application relates to respiratory masks that closely cover the mouth and nose regions together so that the wearer can inhale medical or scented substances without allowing the inhaled substances to directly contact the skin of the user. The present application can also be manufactured with N95 technology for better protection of the user from infection by micro-bacteria and viruses. The mask is secured by straps attached to both ends of the mask and is cinched behind the wearer's head; or the mask is secured by two rubber bands on either side of the mask, each rubber band rotating behind the wearer's ear; or one or more elastic strands are worn behind the wearer's head. A flexible metal nose bridge is provided. The mask is suitably secured around the nose when the nose bridge is pressed with two fingers towards both sides of the nose.

In the present application, the mask is comprised of at least two layers, both layers filtering inhaled and exhaled air. The mask may also be manufactured with N95 technology. The mask layer is composed of a nonwoven fabric, typically made of a polymer, such as polypropylene (as one example). The fabric holes are designed to prevent the passage of dust, bacteria, viruses, and other contaminating suspensions in the air. The outer layer of the mask is formed of tissue that does not allow liquid to pass therethrough. Such liquids may include droplets resulting from sneezing or coughing by another person near the wearer of the mask, as well as various body fluids (such as blood, mouth water, etc.) of the patient in the mask used by medical personnel. The inner layer, which contacts the user's face, is composed of tissue that absorbs liquid (e.g., droplets derived from the user's cough, sneeze, or mouth water). All layers are composed of tissue that allows air to pass through and decontaminate bacteria, viruses, dust and other things.

The mask of the application is characterized in that a breathing member is provided, which is mounted on one or both sides of the mask, or in front of the mouth-nose area. The breathing member carries a lid (cap) shaped to resemble the neck of a water bottle. The cover is spirally rotated to be closed and opened. The cover may have holes (windows) on its surface or may not have any openings. The bottom of the respiratory has an annular lip that is mounted to the mask layer. The breathing member is open from the inside (hollow). The outer (upper) portion of the respiratory member is covered by a cover (cap) that can be completely removed from and installed against the neck of the respiratory member. The interior of the respiratory member has a mesh disposed therein to inhibit contact with the skin of the wearer of the mask. There may be no lateral window (slot) in the breathing member or its cover.

The cover of the respiratory element contains a tablet inside, made of cotton (or any other suitable tissue). The tablets may be impregnated with a volatile medical or scented substance. The tablet fills the cap of the breathing member tightly from the inside. The lid containing the tablets therein is individually wound in a sealed enclosure (package). When the mask user wishes to use a particular medical or flavored substance, he or she tears the package and withdraws the cap (cap) containing the tablet, and then installs the cap on the mask respiratory without touching the tablet inside the cap.

Description of the embodiments

Figures 1, 2, 3 and 4 illustrate a respiratory mask (11) that covers the mouth and nose area of a user (40). The mask has an inner layer (13) (fig. 4) that contacts the wearer's face and an outer layer (12) that faces the external environment of the user (40). The mask (11) may be composed of two or more layers. The outer layer (12) illustrates a respiratory component (20) that may contain a tablet impregnated with a medical or flavored substance. Fig. 4 illustrates the shape of the respiratory element (20) from inside the mask (11), with protruding mesh (25) at the bottom of the respiratory element (20). The protruding mesh prevents the contents of the respiratory element (20) from contacting the skin of the wearer (40) of the mask (11). The mask (11) has means for securing to the face (40) of the wearer. The securement means may be annular rubber or elastic bands (14) on both sides of the mask (11) such that each elastic band (14) wraps around the head of the wearer (40). -providing two rubber bands (or more) connected to the side of the mask (11), each rubber band rotating from the rear around the head of the wearer (40); or a fabric strip tied behind the user's head (40). A flexible metal nose bridge (15) is provided over the upper portion of the mask (11). The nose bridge (15) is positioned over the nose, which causes the mask (11) to tighten around the position of the nose when the nose bridge (15) is pressed against the sides of the nose by two fingers, thereby reducing air leakage.

The face mask (11) is made up of at least two fabric layers. Each layer is made of nonwoven fibers that are breathable and air-filterable to prevent the ingress of bacteria, viruses, pathogens and dust particles. The outer layer (12) of the mask (11) -in addition to the above-is characterized by tissue that absorbs small droplets formed by coughing or sneezing of the user (40) of the mask to prevent these secretions flowing from the mask to the external environment. Furthermore, the present application can be manufactured with N95 mask technology to purify minute bacteria and viruses.

The respiratory element (20) is used for placing a tablet (24) impregnated with a medical or perfumed substance with inhalation. The tablet (24) is attached to the lid (cap) (21) from the inside. Fig. 5 illustrates the detailed structure of the respiratory member (20) with the tablet (24). The respiratory member (20) has a cylindrical neck (26) with an open end, and a lid (cap) (21) that is completely removable from the cylindrical neck (26) of the respiratory member (20) and is mounted on the cylindrical neck (26) of the respiratory member (20).

The base of the respiratory element (20) is formed by one or two rings. If two layers, the two layers have the same diameter and thickness. The upper ring (31) appears to be located on the surface of the outer layer (12) of the mask (11) and the lower ring (32) appears to be located on the surface of the inner layer (13) of the mask (11). The respiratory element remains empty from the inside of the layer of the mask (11). The base of the respiratory element (20) may be formed of only one ring, the respiratory element (20) base being mounted in the mask (11), the respiratory element (20) base being secured to the mask (11) by ultrasonic welding or any other securing means.

Fig. 5 and 6 illustrate the internal structure of the cap (21) of the breathing member (20). The cover (21) may be provided with openings (holes or windows) on its surface. The cover (21) may be provided with no openings (holes or windows) on its surface as shown in fig. 6. Fig. 7 illustrates a tablet (24) located inside a cap (21) provided with an opening (hole or window) (23). The interior contains tablets (24), caps (21), whether with (23) or without holes on their surface, individually packaged in a package (pack) (35), as shown in fig. 11. The tablet (24) is attached internally to the lid (cap) 21 and is impregnated with a flavoured or medical substance.

The tablet (24) inside the cap (21) may be impregnated with one or more fragrances or perfumes. The tablet (24) may contain a medical substance to be inhaled, such as a substance that can treat symptoms associated with colds, influenza, asthma, and the like. The tablet (24) may be made of natural material (cotton, linen, or the like), any synthetic, paper, or other substance that allows the fragrance or medical substance to remain as long as possible in the tissue and not evaporate quickly from the tissue. After removing the cap (21) containing the tablet (24) from the package (35), the cap (21) is tightly secured to the neck (26) of the wearer by rotation.

Notably, the fabric of each layer of the face mask (11) is a nonwoven fabric made of, for example, but not limited to, polypropylene (PP) or polyethylene terephthalate (PET), or both. The tissue of each layer of the mask (11) may be made of any suitable material with micro-holes that prevent the passage of dust, bacteria, viruses and other contaminants.

The mask (11) described in the present application may be made of two or more layers, depending on the nature of the use of the mask (11); and an additional layer comprising activated carbon that can be added to absorb undesirable odors from the external environment.

The method of securing the mask (11) to the face of the wearer varies according to the requirements. The mask may have two rubber bands (14) on either side so that either rubber band wraps around the ears of the wearer (40). Furthermore, the mask (11) may be fixed to the face by a rubber band (two rubber bands) wound around the head of the wearer (40) from the rear. The mask may also be secured by a fabric strap (two or more on each side of the mask (11)) that is tied behind the head of the mask wearer (40).

The respiratory member (20) is made of a lightweight resilient (or similar) material so that the respiratory member does not rupture due to any mechanical pressure and its fragments do not harm the mask wearer (40) or others.

The mask (11) may have different shapes including, but not limited to, the following: cup or bowl shape, folded shape, duckbill shape, fish mouth shape, or any other shape.
