Description

Technical Field

[0001] This utility model relates to the field of packaging, and in particular to a novel aerosol delivery device. Background Technology

[0002] Aerosol delivery devices typically include an aerosol actuator and a canister containing liquid medication and propellant mounted on it. In use, pressing the actuator and canister compresses the gas, and releasing the pressure causes the liquid medication to be sprayed out in an atomized form, thereby delivering the medication.

[0003] Normally, when a user performs the pressing action, they place their thumb on the bottom of the actuator, their index finger or index and middle fingers on the top of the canister, and the remaining fingers on the outer periphery of the actuator. They then apply force to displace the two parts relative to each other to administer the medication. However, most existing actuators use a standardized cylindrical design that is not adapted to hand shape, making it inconvenient for users to hold and requiring repeated attempts to master the operation method.

[0004] In addition, some users have a need to clean the actuator, which requires removing the canister from the actuator, and the existing cylindrical design is not convenient for operation. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a novel aerosol delivery device.

A second opening is provided on one side of the lower portion of the first housing, and the liquid outlet channel communicates with the accommodating space through the second opening. A valve seat adapted to the aerosol valve stem is provided on the inner wall surface of the pressing bottom wall.

[0008] The lower part of the outer wall of the first housing is provided with a reinforcing wing. The reinforcing wing includes two wing pieces.

Detailed Implementation

[0025] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0026] This invention proposes a novel aerosol delivery device, including an actuator 1 adapted to the aerosol can. The actuator has been improved to facilitate user handling, use, and cleaning.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the actuator includes a main body 10 and a liquid outlet 11. The main body is an accommodating space with one end open, enclosed by a first housing 100 and a pressing bottom wall 101. An aluminum can containing liquid medicine and propellant is disposed within the accommodating space, with the can body partially placed outside the accommodating space. In one embodiment, a valve seat 12 is provided on the pressing bottom 101, and correspondingly, a valve stem is disposed on the can body. When the can body is placed within the accommodating space, the valve stem is disposed within the valve seat 12, forming a valve component. By applying pressing pressure to the actuator or the can body, the valve component is opened, allowing the liquid medicine to be sprayed out in a mist form through the liquid outlet, completing one administration.

[0028] The liquid outlet includes a liquid outlet channel 111 with openings at both ends, enclosed by a second housing 110. The central axis of the second housing 110 forms a certain angle with the central axis of the first housing 100; in this design, the angle is an obtuse angle. Specifically, the liquid outlet channel 111 connects to the bottom side of the accommodating space. A second opening 102 is provided on the lower side of the first housing 100, and the liquid outlet channel 111 communicates with the accommodating space through the second opening 102. In one embodiment, the first housing 110 and the second housing 110 are integrally formed.

[0029] Furthermore, in order to ensure the atomization effect and the accuracy of drug delivery, the valve seat 12 includes a valve stem hole 120 adapted to the valve stem and a nozzle 121 opened on one side of the valve seat 12 and communicating with the valve stem hole 120. The nozzle 121 is opposite to the liquid outlet channel 111, so that the atomized drug liquid sprayed from the nozzle 121 can be delivered to the user through the liquid outlet channel 111 with as little residue as possible.

[0030] Furthermore, such as Figure 5 As shown, the bottom of the valve seat 12 is integrally connected to the inner wall of the liquid outlet channel through the guide plate 15; and the guide plate 15 has a concave arc surface, which to a certain extent ensures that the liquid can be delivered with less residue.

[0031] Please combine Figure 2 , Figure 3 and Figure 4 The biggest improvement of this utility model compared to the prior art lies in the fact that a reinforcing wing 13 is provided protruding from the lower part of the outer wall surface of the first housing 100. Specifically, the reinforcing wing 13 includes two wing pieces, which extend from both sides of the second opening along the outer wall surface of the first housing away from each other and extend downward to the pressing bottom wall 101. More specifically, each of the two wing pieces includes a first wall 130 extending along the outer wall surface of the first housing 100 and a second wall 131 extending to the pressing bottom wall; Figure 3 As shown, the first ends of the two wing pieces extend from both sides of the second opening 102 along the outer peripheral wall of the first housing 100, and the two wing pieces do not intersect after extension, that is, there is a clearance interval 132 between the second ends of the two wing pieces. When the actuator is picked up, the friction between the hand and the actuator is increased. More importantly, the clearance interval 132 is arranged opposite to the liquid outlet, that is, it is respectively arranged on the opposite side of the first housing. When picking up the actuator in daily life, such as when holding the actuator with your hand, the palm part can be placed on the clearance interval 132, while the fingers hold the reinforcing wing 13.

[0032] Furthermore, the thickness of the first wall 131 gradually increases from the first end connected to the edge of the second opening towards the second end away from the second opening; this makes it more suitable for the hand. Also, the upper edge of the first wall 121 has a contoured arc surface, which makes it more suitable for the hand when holding or separating the actuator, increasing comfort and convenience.

[0033] Furthermore, the two second walls 132 completely or partially cover the pressing bottom wall 101, thereby forming a thickened wall on the outer surface of the pressing bottom wall 101. This not only increases the force application area of ​​the pressing bottom wall, but also provides enhanced protection when a certain pressure is applied to the valve seat during drug administration. In addition, a pressing part 14 is formed in the middle region of the thickened wall or the middle region of the pressing bottom wall. The pressing part 14 is a concave arc surface that conforms to the thumb, making it fit the thumb better. At the same time, the pressing part 14 includes several anti-slip protrusions 140.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
