Description:FIELD OF INVENTION
[0001] Embodiments of the present disclosure relate to the field of pharmaceutical fluid medication accessories and more particularly to a nasal spray pump and a method thereof.

BACKGROUND
[0002] Typically, a nasal spray dispenser play an essential role in the administration of nasal medications, offering a targeted delivery method that ensures drugs are directly applied to the nasal mucosa. These medical care devices are particularly useful in treating conditions like allergies, nasal congestion, and sinusitis, where quick, localized drug absorption is key to providing relief. Unlike oral medications, nasal sprays can bypass the digestive system, reducing the chances of systemic side effects while promoting faster therapeutic action. As the demand for efficient and precise drug delivery systems continues to rise, nasal spray dispensers are evolving to meet the needs of both patients and healthcare providers.

[0003] The existing nasal spray dispensers typically rely on mechanical or pressurized mechanisms to dispense medication. Most commonly, the devices are designed with a housing that holds the drug and a movement control mechanism when activated, releases a specific dose into the nasal cavity. In these dispensers, the internal components and locking structures work together to ensure that the correct amount of medication is dispensed with each movement. The nasal spray dispenser aims to maintain a stable spray pattern and consistent dose, while providing ease of use and reliability in delivery.

[0004] Despite there are several existing designs for nasal spray pumps, there remain a significant drawback persist to their design and operation. Firstly, the potential for inconsistent dosing due to variations in how the movement control mechanism is utilized leads to suboptimal drug delivery. The presence of locking elements and peripherals, while designed to secure a movement control unit and piston, may also create friction or wear, impacting the smoothness of the spray and causing clogging or difficulty in movement. In some cases, the spray pattern may not be uniform, affecting the therapeutic effectiveness of the medication. Additionally, the complexity of the components and potential for buildup over time can reduce the overall durability and reliability of the device, leading to patient frustration.

[0005] In response to these challenges, there exists a need to address these challenges and provide a solution that addresses the consistency of dose delivery and improves the smoothness of operation. The proposed designs by refining an organization of the key components including supporting structures can achieve smoother and more consistent motion, minimizing resistance and the likelihood of obstructions. Incorporating additional strategically positioned openings in an internal mechanism improves force transmission, promoting more controlled and uniform output with broader distribution, thereby enhancing overall performance and efficiency during operation.

[0006] Hence, there is a need for an improved nasal spray pump which addresses the aforementioned issue(s).

OBJECTIVES OF THE INVENTION
[0007] The primary objective of the invention is to provide a nasal spray pump with a novel housing design, featuring ribs extending radially between the housing's inner and outer surfaces. These ribs have an L-shaped structure, with free end tips connected to a curved surface for enhanced structural integrity. This design ensures improved durability and support for the pump mechanism.

[0008] Another objective of the invention is to utilize an actuator of the nasal spray pump adapted to incorporate three locking structures evenly spaced around the inner periphery, enabling easy attachment, removal, and smooth movement. Each locking structure is equipped with four ribs, providing additional stability and reliability during operation. This configuration allows for effective control over the actuator’s movement.

[0009] Yet another objective of the invention is a piston of the pump featuring four equidistant rectangular holes, which enhance spray accuracy. These windows provide a stable, focused thrust, resulting in a precise and consistent spray pattern. The combination of these features ensures a wider spray angle and better overall performance, making the invention highly efficient.

Furthermore, the actuator unit includes a spring coupled to the piston wherein the spring is adapted to compress when the actuator unit is operated by the user, causing the piston to move downward to create a vertical reciprocation motion and simultaneously cause the ball to move downward to prevent backflow of the fluid.
[0017] It is to be noted that the nasal spray pump discussed herein is called as ‘Nasipod’.
[0018] FIG. 1 is a schematic representation of the nasal spray pump of FIG. 1 in accordance with an embodiment of the present disclosure. Typically, the nasal spray pump is used to deliver a fine mist of liquid medication into the nasal passages of a user ( a patient). The nasal spray pump includes a housing unit (105) and an actuator unit (125) . The housing unit (105) protects and supports the internal components of the nasal spray pump. The actuator unit (125) is the part of the nasal spray pump that the user interacts with. The actuator unit (125) includes a nozzle (130, FIG. 2) that is enclosed by an over cap unit (155). Typically, the over cap unit (155) is accountable to prevent from any environmental dust.
[0019] The fluid that needs to be sprayed is accommodated in a container (110). In the foregoing discussion, the container (110) may also be referred to a ‘reservoir’ or ‘a bottle’. Examples of the fluid includes, but is not limited to, decongestants, antihistamines, steroids, other medical formulations and other solutions.
[0020] FIG. 2 is a cross sectional view of a nasal spray pump in accordance with an embodiment of the present disclosure. The housing unit (105) is adapted to interlock with the container (110). In one embodiment, the interlock is a ‘snap fit’ (push-to-lock). Examples of snap fit includes, but is not limited to, cantilever snap fit, annular snap fit and torsional snap fit. It will be appreciated to those skilled in the art that the interlock may also be a treaded connection or crimped seals and is not limited to the said. Typically, when force is applied, a flexible part of the housing unit (105) deforms temporarily and then snaps back into place, thereby locking the housing unit (105) with the container (110). The flexible part is made from durable materials such as polypropylene (PP), polyethylene (PE), or ABS plastic.
[0021] Further, the housing unit (105) includes a hollow protruding tube (115)to accommodate a dip tube (120)wherein the dip tube (120)is adapted to draw the fluid from the container (110).
[0022] Furthermore, the housing unit (105) includes a plurality of first ribs extending radially between an inner surface of the housing unit (105) and an outer surface of the hollow protruding tube. Each of the plurality of first ribs (402) comprises an L-shaped structure (404) with a free end tip joined to a curved surface of the tube.
[0023] The actuator unit (125) is positioned on a top section of the housing unit (105) wherein the actuator unit (125) is adapted to move in a reciprocal motion upon application of a downward pressure by a user to initiate a dispensing action of a fluid. Typically, the actuator unit (125) is accountable for triggering a pump mechanism (when the actuator unit (125) is pressed, it activates the pump inside the housing unit (105). Further, the actuator unit (125) ensures that the fluid is dispensed in a fine mist or controlled droplets.
[0024] In one embodiment, the actuator unit (125) is conical or tapered cylindrical in shape. The actuator unit (125) gradually narrows from a wider base to a smaller top, similar to a cone. This type of shape is used when a compact, pointed design is required. Alternatively, the actuator unit (125) may have a cylindrical body that gradually decreases in diameter toward the nozzle (130) end. This type of design provides better grip and ergonomic handling. It must be noted that the shape of the actuator unit (125) is intentionally designed to improve the user experience and spray performance.
[0025] The actuator unit (125) includes a nozzle (130) adapted to dispense the fluid. The nozzle (130) fits comfortably in an ergonomic surface for easy pressing. Further, in one embodiment the nozzle (130) is enclosed by an over cap unit (155) to prevent from any environment dust. The over cap unit (155) acts as a sealing mechanism that covers the nozzle (130) opening when the spray is not in use, ensuring hygiene, and product longevity. Further, the over cap unit (155) is a removable or hinged cover that fits over the nozzle (130). In one embodiment, the over cap unit (155) is made of plastic (polypropylene or polyethylene), ensuring lightweight, durability, and chemical resistance.
[0026] The actuator unit (125) also includes a plurality of locking structures positioned around an inner periphery (inner circumference) of the actuator unit (125) . The plurality of locking structures are positioned equidistance from each other and adapted to facilitate fixing, removal and a reciprocating movement of the actuator unit (125) . The locking structures prevents accidental detachment during use. Despite being securely fixed, the actuator unit (125) should be removable for refilling, cleaning, or replacement. The locking structures allow controlled detachment when needed. The reciprocating movement refers to up-and-down motion when the user presses and releases the actuator. The locking structures guide this movement smoothly, ensuring efficient pumping of the liquid from the container (110).
[0027] Further, each of the plurality of locking structures (302a, 302b, 302c) comprises a plurality of second ribs (304a, 304b, 304c) adapted to provide strength and rigidity to the plurality of locking structures. Typically, the plurality of second ribs are thin and raised sections to provide extra strength. Particularly, the second ribs (304a, 304b, 304c) reinforce the locking structures (302a, 302b, 302c).
[0028] The housing unit (105) and the actuator unit (125) are sealed via an annular gasket (135) to prevent inadvertent leakage of the fluid. The annular (ring-shaped) gasket is positioned within at least one groove formed inside the housing unit (105) . The sealing mechanism between the housing unit (105) and the actuator unit (125) plays a crucial role in ensuring the proper functioning of the nasal spray pump. The annular gasket, positioned within a groove inside the housing unit (105) ,is the key component that prevents leakage. The groove is a recessed channel or indentation where the gasket fits securely. This ensures that the gasket remains in place during use and effectively seals the connection.
[0029] Further, the annular gasket (135) is made of a material that is flexible, durable, resistant to chemicals and leak-proof. Examples of the material includes, but is not limited to, silicone rubber, Ethylene Propylene Diene Monomer (EPDM) rubber or Thermoplastic Elastomer (TPE).
[0030] In one embodiment, the annular gasket (135) comprises a dual-layer structure, with an inner core made of a rigid or semi-rigid material and an outer layer made of a flexible sealing material. This combination prevents leakage.
[0031] Further, the actuator unit (125) includes a piston (140) adapted to cause a pressure to facilitate controlled dispensing of the fluid. The piston (140) is a critical component that generates pressure to enable the controlled release of liquid from the nasal spray pump. The piston (140) includes at least four rectangular shaped holes (502a, 502b, 502c, 502d) arranged equidistantly from each other. Further, the at least four rectangular shaped holes (502a, 502b, 502c, 502d) are adapted to provide a stable, focused, and robust thrust ensuring an accurate, stable and wider spray angle and spray pattern from the nozzle (130) during actuation. Specifically, the at least four rectangular shaped holes (502a, 502b, 502c, 502d) ensures smooth airflow and liquid flow through the piston (140) and also divides the pressure evenly across multiple exit points. It must be noted that the equidistant spacing ensures consistent and uniform airflow around the liquid. Further, the equidistant spacing ensures even pressure distribution, thereby preventing erratic spray patterns.
[0032] In one embodiment, a lubricant is applied inside the piston (140 to ensure that the housing unit (105) moves smoothly inside the piston (140).
[0033] The actuator unit (125) also includes a spring coupled to the piston (140) wherein the spring is adapted to compress when the actuator unit (125) is operated by the user, causing the piston (140) to move downward to create a vertical reciprocation motion and simultaneously cause a ball (150) to move downward to prevent the backflow of the fluid.
[0034] In one embodiment, the spring is adapted to expand when the actuator unit (125) is operated by the user, causing the piston (140) to move upward, thereby creating a vacuum that enables the dip tube (120)to draw the fluid from the container (110) and simultaneously causing the ball (150) to move upward, thereby priming for a next dispensing cycle.
[0035] In one embodiment, the spring is composed of a metallic material. The metallic material provides elasticity, high strength and durability. Examples of the metallic material includes, but is not limited to, stainless steel, music wire, phosphor bronze, beryllium copper and nickel-titanium.
[0036] In one embodiment, the housing unit (105) includes the ball (150) positioned at a top section of the hollow protruding tube (115)to regulate flow of the fluid. The ball (150) is a small spherical component, typically made of plastic, rubber, or stainless steel, that controls the flow of the liquid inside the pump mechanism. In this case, it is placed at the top section of the hollow protruding tube, which is the fluid pathway connecting the dip tube (120)to the nozzle (130). The ball (150) acts as a one-way valve, meaning it only allows fluid to move in one direction (from the container (110) to the actuator) while preventing backflow. When the spray pump is not in use, the ball (150) remains in its default position, blocking the fluid pathway. Gravity and internal pressure keep the ball (150) seated, preventing fluid leakage. When the user presses down on the actuator, the piston (140) moves downward, creating pressure inside the hollow protruding tube. This pressure forces the ball (150) to move downward to prevent the backflow of the fluid. At this point, the fluid is dispensed. As the user releases the actuator, the spring inside the pump expands, moving the piston (140) back to its original position. The fluid is drawn from the container into the dip tube (120). .
[0037] Typically, the operation of the nasal spray pump involves the functionality of five main components namely, the spring, piston (140), dip tube, ball (150) and nozzle (130). The spring creates a return force after compression thereby ensuring that the actuator unit (125) returns to its original position after each use. The piston (140) typically moves downwards when the user presses the actuator unit (125) . This creates the pressure that draws the fluid from the container (110) and pushes it through the nozzle (130). The dip tube (120)is responsible for lifting the fluid upward as the piston (140) creates a suction. The ball (150) acts as a one-way valve, thereby ensuring that fluid moves only towards the nozzle (130) and not back into the container (110). The final exit point is through the nozzle (130) where the pressurized liquid is converted into a fine mist for nasal delivery.
[0038] Consider a non-limiting example where a patient ‘X’ uses the nasal spray pump to nasal congestion relief. User ‘X’ picks up her nasal spray pump. Inside the container (110), there is a hollow protruding tube (115) that holds a dip tube. The dip tube (120)is already submerged in the medicated liquid, ensuring that fluid can be drawn up when pressure is applied. The housing unit (105) inside the container (110) has first ribs that ensure structural stability. These ribs support the hollow tube, preventing it from bending or breaking when User ‘X’ presses the spray. User ‘X’ places her index and middle fingers on the sides of the actuator unit (125) and her thumb on the base of the container (110).
[0039] . Inside the actuator unit (125) , locking structures ensure that User ‘X’ can remove or reattach the actuator if needed. These structures also help guide the reciprocating motion, preventing misalignment. To ensure durability, second ribs (304a, 304b, 304c) reinforce the locking structures inside the actuator unit (125) . This prevents deformation of the actuator, ensuring the spray mechanism remains functional even after multiple uses. User ‘X’ notices that even after multiple uses, there is no leakage from the nozzle (130). The annular gasket (135) inside the housing unit (105) prevents liquid from leaking.
[0040] In operation, when User ‘X’ presses the actuator for the first time, the actuator, piston and ball moves downwards. Consequently, when User ‘X’ releases the pressure, the actuator moves upwards causing the piston and the ball to move upwards as well. At this point, the dip tube is adapted to draw the fluid from the container. Now, User ‘X’ presses the actuator for the second time. This again causes the actuator, piston and ball to move downwards and causes the fluid to be dispensed through the nozzle. Further, the position of the ball prevents backflow of the liquid into the container. This completes one cycle of dispensing the fluid. The same operation is performed for additional dispense of the fluid. It must be noted that at every dispense, a predetermined volume of the fluid is sprayed for use. In other words, the nasal spray pump is a metered dose pump that releases a precise and metered dose at each operation. The nasal spray is successfully released, delivering the medication in the right dose and spray pattern.

[0042] FIG. 3a is a schematic representation of an exterior view of the actuator unit (125) . The actuator unit (125) includes a plurality of ribs (300a, 300b, 300c) for better griping.
[0043] FIG. 3b is a schematic representation of an interior view of the actuator unit (125) . It can be seen in FIG. 3b that there are three locking structures (302a, 302b, 302c) arranged equidistantly from each other around the inner periphery. Each of the three locking structures includes three ribs (304a, 304b, 304c).

[0049] FIG. 7a, FIG. 7b and FIG. 7c are schematic representations of the working of the nasal spray pump of FIG. 1 in accordance with an embodiment of the present disclosure.
[0050] FIG. 7a illustrates a normal position of the nasal pump spray (100) before operation.
[0051] FIG. 7b illustrates a partial compression of the nasal pump spray (100) to dispense the spray from the nozzle. The partial compression causes the piston (140) and the actuator (125) to move downwards. Simultaneously, the ball (150) moves downward allowing the fluid to pass through the nozzle (130) for release. Additionally, the ball (150) prevents the backflow of the fluid.
[0052] FIG. 7c illustrates a completely compressed pump upon dispensing the spray. The complete compression causes the piston (140) and the actuator (125) to move upwards. Subsequently, the ball (150) moves upwards to allow the fluid to be drawn into the dip tube (120) from the container (110). FIG. 8a illustrates a flow chart representing the steps involved in a method (800) to operate the nasal spray pump in accordance with an embodiment of the present disclosure. FIG. 8b illustrates continued steps of the method (800) of FIG. 8a in accordance with an embodiment of the present disclosure. The method (800) includes accommodating, by a hollow protruding tube of a housing unit, a dip tube (120)wherein the dip tube (120)is adapted to draw the fluid from the container (110) wherein the housing unit is adapted to interlock with a container (110) accommodating a fluid in step 805.
[0053] The hollow vertical tube is a vertical tube inside the nasal spray pump’s housing unit. It extends downward into the container (110) and serves as a fluid passageway. The dip tube (120)is a thin, elongated tube that is inserted into the hollow protruding tube. Its function is to draw the liquid medication from the bottom of the container (110) when the pump is activated. It must be noted that the main body of the nasal spray pump is the housing unit that holds and secures all components.
[0054] In one embodiment, the ball (150) positioned at a top section of the hollow protruding tube to regulate flow of the fluid.
[0055] When the actuator unit is pressed, a vacuum effect occurs inside the hollow protruding tube. The dip tube (120)inside the fluid container (110) draws the liquid medication upward. The liquid passes through the hollow tube and reaches the nozzle, where it is released as a fine mist.
[0056] The method (800) includes extending radially, by a plurality of first ribs of the housing unit, between an inner surface of the housing unit and an outer surface of the hollow protruding tube, wherein each of the plurality of first ribs comprises an L-shaped structure with a free end tip joined to a curved surface of the tube in step 810.
[0057] The plurality of first ribs creates a stable connection, ensuring that the hollow tube stays in place and does not shift when the actuator is pressed. Each rib has an L-shape, which means that one side of the rib extends along the inner wall of the housing unit and the other side attaches to the curved surface of the hollow protruding tube. The free end tip of each rib is attached to the curved surface of the hollow tube. This ensures that the hollow tube is firmly supported and does not bend or become misaligned over time.
[0058] The method (800) includes moving, by an actuator unit positioned on a top section of the housing unit, in a reciprocal motion upon application of a downward pressure by a user to initiate a dispensing action of a fluid in step 815. The user presses the actuator unit downward, forcing the internal piston and spring mechanism to move down This downward movement creates pressure inside the pump. The pressure forces the ball inside the pump to open. Liquid medication is drawn from the container through the dip tube and into the hollow protruding tube. The fluid travels up through the hollow protruding tube and reaches the nozzle. It is then atomized into a fine mist and sprayed into the user's nasal passage. When the user releases the actuator, the spring pushes it back up. This restores the original position of the internal components, closing the ball and stopping the fluid flow. The reciprocal motion resets the pump for the next actuation cycle.
[0059] In one embodiment, the actuator unit is conical or tapered cylindrical in shape.
[0060] The method (800) includes dispensing, by a nozzle of the actuator unit, the fluid in step 820. It must be noted that, the piston, ball, and dip tube inside the actuator work together to push the fluid up from the container and through the nozzle.
[0061] In one embodiment, the nozzle is enclosed by an over cap unit to prevent from any environmental dust.
[0062] The method (800) includes facilitating, removing and causing a reciprocating movement of the actuator unit, by a plurality of locking structures of the actuator unit positioned around an inner periphery of the actuator unit, wherein the plurality of locking structures are positioned equidistance from each other in step 825. The locking structures guide the actuator’s downward motion, ensuring a smooth, controlled press. When the actuator unit is released the spring pushes it back up, and the locking structures help it return to its original position.
[0063] The method (800) includes providing, by a plurality of second ribs of each of the plurality of locking structures, strength and rigidity to the plurality of locking structures in step 830. It must be noted that without these second ribs, the locking structures could weaken, leading to lose or unstable movement, making the nasal spray pump less effective.
[0064] The method (800) includes preventing, by an annular gasket that seals the housing unit and the actuator unit, inadvertent leakage of the fluid in step 835. The annular gasket is positioned within at least one groove formed inside the housing unit. The groove inside the housing unit holds the annular gasket securely in place. This prevents the gasket from shifting or becoming loose over time. When the actuator unit is assembled with the housing unit, the gasket compresses to form a leak-proof seal. This stops fluid from escaping around the actuator, e1nsuring all liquid exits only through the nozzle.
[0065] In one embodiment, the annular gasket comprises a dual-layer structure, with an inner core made of a rigid or semi-rigid material and an outer layer made of a flexible sealing material.
[0066] The method (800) includes causing, by a piston, a pressure to facilitate controlled dispensing of the fluid in step 840. The piston comprises at least four rectangular shaped holes arranged equidistantly from each other. The plurality of rectangular shaped holes are adapted to provide a stable, focused, and robust thrust ensuring an accurate, stable and wider spray angle and spray pattern from the nozzle during actuation.
[0067] When the user presses down on the actuator, the piston moves downward, compressing the fluid in the chamber. This creates pressure inside the pump system, which pushes the fluid toward the nozzle. As fluid moves through the piston, it passes through multiple rectangular-shaped holes. These holes regulate the pressure and control the fluid flow, preventing uneven spraying. The rectangular holes ensure that the fluid is dispersed evenly and with a consistent force. This prevents uneven bursts and ensures a smooth, controlled release from the nozzle. The positioning of the holes helps create a uniform mist, ensuring a wider spray coverage. The result is a well-distributed, fine mist that effectively reaches the nasal cavity.
[0068] The method (800) includes compressing, by a spring coupled to the piston when the actuator unit is operated by the user, causing the piston to move downward to create a vertical reciprocation motion and simultaneously cause the ball to move downward to prevent backflow of the fluid in step 845.
[0069] In one embodiment, the spring is adapted to expand when the actuator unit is operated by the user, causing the piston to move upward and simultaneously causing the ball to move upward to dispense the fluid to pass through the nozzle for release.
[0070] In one embodiment, the spring is composed of a metallic material.
[0071] Various embodiments of the nasal spray pump provides several advantages. The snap fit locking mechanism prevents accidental opening or contamination. The annular gasket creates a tight seal between the actuator and housing unit thereby ensuring that the fluid is not wasted or lost. It also blocks air entry to keep pressure stable inside the pump. Further, the annular gasket Regulates pressure buildup and release during actuation. Another benefit is the use of the first ribs that play a crucial role in structural stability, durability, and efficient fluid flow within the nasal spray pump. Their L-shaped structure and radial positioning provide multiple advantages that enhance the performance and longevity of the device. The at least four rectangular shaped holes (502a, 502b, 502c, 502d) in the piston (140) adapted to provide a stable, focused, and robust thrust ensuring an accurate, stable and wider spray angle and spray pattern from the nozzle during actuation.
