Description

Nasal and oral sprays {SPRAYER FOR NASAAL CAVITY}

The present invention relates to a nasal and oral nebulizer having a nozzle structure capable of spraying a chemical solution contained in a container into the nasal cavity or the oral cavity.

Sprays containing medicinal solutions are often used to relieve or treat symptoms of respiratory diseases such as asthma or rhinitis. The user can self-treat and prevent respiratory diseases by widely applying a liquid containing pharmaceutical ingredients that relieve symptoms of respiratory diseases to a deep position inside the nose or inside the mouth.

A nebulizer for delivering this medicine to the inner mucous membrane of the nose, that is, the nasal cavity, is useful for the prevention and treatment of specific diseases or disorders related to the nose. Conventionally, a spray device for applying a chemical solution to the nasal cavity is known in various prior art. However, in order to spray the chemical liquid present in the liquid form in the container in the form of a spray, the spraying device may further include, for example, a manually or automatically operated pump. However, such devices have a number of disadvantages. In the case of a manual pump, the spraying usually did not reach the optimum characteristics due to fluctuations according to the degree of application of the driving force. In addition, when a pressurized aerosol canister or the like is used instead of a manual pump, the number of parts is increased, so that price competitiveness is lowered, the service life is short, and there are problems that it is only a one-time use.

On the other hand, the spraying device may spray the chemical not only in the form of a spray, but also in the form of a liquid, if necessary. When the chemical liquid is sprayed, the chemical liquid is sprayed in the form of a stream through the nozzle. In this case, a nozzle for separate injection should be further provided in the spraying device. This has a problem of complicating the structure of a single spraying device.

1 is a perspective view of a nasal and oral spray according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the nozzle tube portion of FIG. 1 in the maximum inserted state, FIG. 3 is an exploded perspective view of FIG. Fig. 2 is an enlarged view seen from the first position, and Fig. 5 is an enlarged view of Fig. 2 seen from the second position. 1 to 5, the nasal and oral spray according to an embodiment of the present invention includes a container portion 100, a container stopper 200, a nozzle tube portion 300, a nozzle tube cap 400, and the like. do.

The container unit 100 has an overall shape similar to that of a jar, and is formed of a flexible material such as synthetic resin. The container part 100 accommodates the chemical, and when an external force is applied, the container part 100 is temporarily deformed in shape and then restored. For this reason, when the user presses the container part 100 in a state in which the container part 100 is gripped, the internal pressure is adjusted by the temporary deformation of the container part 100 according to the pressing. That is, when the user presses the container part 100, the chemical liquid may be sprayed or sprayed to the outside of the nasal and oral sprayers through the nozzle tube part 300 due to a change in internal pressure. Alternatively, the container part 100 may be formed of a solid material. At this time, a button part is further disposed on the container part 100 or the container stopper part 200, and according to the operation (pressing, etc.) of the button part, the chemical is introduced into the nozzle pipe part 300 by, for example, pumping, etc. , then it may be sprayed or sprayed to the outside of the nasal and oral sprayers through the flow path.

The container closure part 200 is coupled to the upper end of the container part 100 . To this end, a stopper groove is formed on the lower side of the container closure part 200 , and a screw thread may be formed on the inner circumferential surface of the stopper groove. Correspondingly, a thread may be formed in the container part 100 as well. On the other hand, a sealing hole 220 through which the nozzle tube part 300 can be coupled is formed in the center of the container closure part 200 .

The nozzle pipe part 300 is coupled through the container closure part 200, a flow path is formed in the longitudinal direction, and the chemical liquid is sprayed through the spray hole 362 formed in the longitudinal direction, or at least one or more formed in the radial direction. It is formed to be discharged through the communication hole 340 . This nozzle tube part 300 is made of, for example, a silicon material, and its shape has a long and thin straight tube structure similar to a straw straw. In addition, the nozzle pipe part 300 can freely adjust the direction of the flow path by applying a bellows structure to a part thereof. At this time, the chemical liquid moves through the flow path formed in the nozzle pipe part (300).

On the other hand, the nozzle pipe part 300 is hermetically coupled to the container closure part 200 . This prevents the chemical from leaking into the gap existing between the nozzle pipe part 300 and the container stopper part 200 . In addition, an O-ring groove may be formed in a circumferential direction at any one location on the inner circumferential surface of the sealing hole 220 . In addition, an O-ring 240 (O-ring) made of a rubber material or the like may be disposed in the O-ring groove. Thereby, the sealing force is improved.

The nozzle pipe part 300 is hermetically coupled to the container closure part 200 in such a way that the O-ring 240 is penetrated again after penetrating the sealing hole 220 . On the other hand, the nozzle tube part 300 may be reciprocally moved in the vertical direction according to the pulling-in/out operation by the user in a state in which the nozzle pipe part 300 is penetrated and coupled to the container closure part 200 . In this case, the incoming and outgoing distance may be adjusted.

The user can pull the nozzle tube 300 to the maximum and withdraw it to the outside of the container 100 as much as possible. (See FIG. 1) When the nozzle tube 300 is withdrawn and extended to the outside of the container 100, the nasal and oral cavity The nebulizer for use will have the use of spraying or injecting a chemical|medical solution not only to a nasal cavity, but to a location deeper in an oral cavity, for example. Alternatively, the user can insert the nozzle pipe 300 into the container part 100 as much as possible by pushing it in. (See FIG. 2 ) When the nozzle pipe part 300 is inserted and inserted into the container part 100, the sprayer can spray or spray the chemical solution into the nasal cavity. In addition, in this state, the portability of the nasal and oral nebulizers can be further improved.

In addition, on the outer peripheral surface of the nozzle tube portion 300, a first jaw 310 for limiting the movement distance of one side of the nozzle tube cap 400 may be formed. The first jaw 310 may be at least one or more protruding jaws that are spaced apart from each other in the circumferential direction on the outer circumferential surface of the nozzle pipe part 300 . In addition, the first jaw 310 may be a protruding ring jaw that is continuously arranged in the circumferential direction on the outer peripheral surface of the nozzle tube portion (300). Here, one side means the direction in which the chemical is ejected through the nozzle tube cap 400 .

In addition, a second jaw 320 for limiting the movement distance of the nozzle tube portion 300 inserted into the container closure portion 200 may be formed. This second jaw 320 also serves to limit the movement distance of the other side of the nozzle tube cap 400 at the same time. The second jaw 320 may be the same protruding protrusion as the first protrusion 310 or may be a protruding ring protrusion. However, the second jaw 320 is formed to protrude more than the first jaw 310 . That is, the height of the second jaw 320 is formed to be higher than the height of the first jaw 310 .

In addition, a third jaw 330 may be formed on the outer peripheral surface of the nozzle tube portion 300 to prevent the nozzle tube portion 300 from being separated to the outside of the container stopper portion 200 . This, the first jaw 310 to the third jaw 330 are sequentially formed in the reverse order to the direction in which the chemical liquid moves in the nozzle pipe part 300 .

The chemical is introduced into one end of the nozzle pipe part 300 , and is sprayed through the spray hole 362 formed at the other end or discharged through the communication hole 340 formed at the end. In addition, the nozzle pipe part 300 may further include a spray head 360 fitted to the other end of the nozzle pipe part 300 . The spray head 360 is formed with a head groove on one surface, and at this time, the inner diameter of the head groove is formed to have the same size as the inner diameter of the nozzle pipe part 300 . At this time, the spray hole 362 is formed in the center of the bottom surface of the head groove. When the spray hole 362 is contaminated due to foreign substances contained in the chemical solution, the user can easily replace the spray head 360 .

The communication hole 340 provides a passage through which the chemical liquid moves from the nozzle pipe part 300 to the nozzle pipe cap 400 . Such, the communication hole 340 is formed perpendicular to the longitudinal direction of the nozzle pipe portion (300). In addition, the communication hole 340 may be formed perpendicular to the flow direction of the nozzle pipe portion 300 .

The nozzle pipe cap 400 allows the communication hole 340 to be opened and closed as the lower through-hole 410 reciprocates in the longitudinal direction of the nozzle pipe part 300 in a state coupled to the outer peripheral surface of the nozzle pipe part 300 . In addition, the end of the nozzle tube portion 300 is accommodated in the nozzle tube cap 400, and an inner space portion 420 through which the chemical liquid moves is formed. In addition, the nozzle pipe cap 400 has an ejection hole 440 is formed at the top so that the chemical is ejected to the outside.

The nozzle tube cap 400 may be moved by the user. In the first position where the nozzle tube cap 400 moves and closes the communication hole 340, a preset separation space 421 is formed between the spray hole 362 and the ejection hole 440 in the inner space portion 420, It is possible to reduce the scattering area of the chemical liquid sprayed through the ejection hole 440 . At this time, the inner space 420 provides a passage through which the chemical liquid sprayed through the spray hole 362 can move to the ejection hole 440 . The spaced space 421 according to an embodiment may include a cross-sectional area reduction space whose cross-sectional area is gradually reduced.

The inner space portion 420 is formed in a shape that can accommodate the nozzle tube portion 300 so that interference does not occur during the reciprocating movement of the nozzle tube portion 300 . This, the inner space portion 420, the lower end communicates with the through-hole 410, the upper end communicates with the ejection hole (440). In addition, the upper side of the inner space 420 may be formed in a truncated cone shape in consideration of the diameter size of the ejection hole 440 . For example, the inner space 420 may have a shape in which an empty cylinder and an empty truncated cone communicate with each other inside the nozzle tube cap 400 .

When the nozzle tube cap 400 is positioned at the first position, the user can spray the chemical by pressing the container unit 100 . At this time, when the chemical liquid in the container part 100 moves through the nozzle pipe part 300 and is sprayed through the spray hole 362, the state is converted from the liquid phase to the spray state. However, the chemical liquid in the spray state is not ejected directly to the outside of the nasal and oral sprays due to the separation space 421 formed between the spray hole 362 and the ejection hole 440 .

The chemical liquid converted into a spray state moves toward the jet hole 440, and can only be jetted to the outside of the nasal and oral nebulizer through the jet hole 440. That is, the scattering area of the chemical liquid initially sprayed through the spray hole 362 may be reduced due to the components of the separation space 421 and the ejection hole 440 . However, instead of decreasing the scattering angle of the chemical solution, the amount of the chemical solution ejected forward may increase.

In addition, in the second position where the nozzle tube cap 400 moves to open the communication hole 340 , the inner space portion 420 has a gap between the outer peripheral surface of the nozzle tube portion 300 and the inner peripheral surface of the nozzle tube cap 400 opposite thereto. A space 423 and a truncated conical space 424 in which the cross-sectional area is gradually reduced between the spray hole 362 and the ejection hole 440 may be formed, respectively.

When the communication hole 340 is opened at the second position, the chemical liquid moving through the nozzle pipe part 300 moves to the inner space part 420 through the communication hole 340 instead of the spray hole 362 . At this time, the chemical is maintained in a liquid state. Meanwhile, the chemical liquid discharged through the communication hole 340 may move through the gap space 423 and the truncated cone space 424 , and may be sprayed in a liquid state through the ejection hole 440 . Since the truncated cone space 424 has a shape in which the cross-sectional area is gradually reduced in the ejection direction, it is possible to increase the ejection speed of the chemical.

In summary, when the nozzle tube cap 400 moves and contacts the first jaw 310 , the chemical is sprayed through the ejection hole 440 , and the nozzle tube cap 400 moves and contacts the second jaw 320 . The chemical is injected through the ejection hole 440 . That is, when using the nasal and oral nebulizer in the spray mode, the user moves the nozzle tube cap 400 so that it comes into contact with the first jaw 310 and then pressurizes the container unit 100 . In addition, when you want to use the nasal and oral nebulizer in the spray mode, the user can move the nozzle tube cap 400 so that it comes into contact with the second jaw 320 and then pressurize the container unit 100 . In this aspect, the first jaw 310 may indicate that the nozzle tube cap 400 is located in the first position. In addition, the second jaw 320 may indicate that the nozzle tube cap 400 is located in the second position.

In the above, preferred embodiments of the present invention have been exemplarily described, but the scope of the present invention is not limited to such specific embodiments, and can be appropriately changed within the scope described in the claims.
