Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical product packaging, in particular to an aerosol container. BACKGROUND

[0002] Aerosol is a commonly used medical device, which can spray the liquid in the container into mist by the pressure of propellant for the treatment of patients. The existing aerosol delivery device usually comprises a container and a valve system arranged above the container. The aerosol valve is a key component of the aerosol, which plays a very important role in the function of the aerosol, and is related to the sealing of the product, the spraying effect, and the stability of the product.

[0003] As shown in the prior art, Figure 1 The aerosol valve usually comprises a push button 1', a sealing cup 2', an outer sealing ring 3', an inner sealing ring 4', a valve rod 5', a valve body 6', a spring 7', a liquid guide pipe 8', and the like. In the non-working state, the valve is in the closed state under the action of the spring 7'. In the working state, when the push button 1' is pressed, the valve rod 5' moves downward, the valve rod spray hole 9' is away from the sealing ring and is in the open state, the rod body and the valve body mixing chamber are communicated, the contents are sprayed from the button spray hole through the conduit, the valve body spray hole, the mixing chamber, and the valve rod under the pressure of the propellant. When the spring pushes the valve rod back, the valve rod spray hole is sealed, and the valve is in the closed state again. The inner sealing ring 4' is used to seal the valve rod spray hole and the inner and outer spaces of the valve body and the sealing cup, and the outer sealing ring 3' is used to seal the sealing cup and the container. The push button is usually installed above the valve rod, and there is no strict sealing between the push button and the sealing cup, so that the valve rod is exposed to the air. When the push button pushes the valve rod downward, the part of the valve rod exposed to the air will mix with the liquid in the valve body by passing through the inner sealing ring, which will pollute the liquid to some extent.

[0004] In addition, after the existing aerosol valve delivers the liquid medicine, the button spray hole is always in the open state, so that the discharged liquid medicine may be left in the discharge port or the spraying channel for a long time, which will cause the liquid medicine to be exposed to the outside and be contaminated or deteriorated.

[0049] The technical solution protected by the present invention is described in detail below with reference to the accompanying drawings.

[0050] like Figure 1 As shown, the liquid outlet unit in existing aerosol valve systems consists of a valve stem 5' and an infusion channel within a valve body 6'. A push button 1' controls the opening and closing of the infusion channel through pumping motion. To prevent residual solution from the injection port or contamination of the solution remaining in the infusion channel by the injection port, a nozzle seal is typically installed at the nozzle. For other non-aerosol pumping valve systems, since the container has no pressure differential, when the pump head is pressed, the pressure inside the container is greater than the pressure outside the container. The pumped solution pushes the nozzle seal located within the nozzle, opening the nozzle. After the liquid is discharged, a spring returns the nozzle seal to the nozzle, continuing to seal. However, this antibacterial method is not suitable for aerosols due to the high pressure inside the bottle.

[0051] The present application provides an aerosol container, comprising a container body and a cover arranged at the opening of the container body, wherein the container body is used for storing an aerosol solution and propellant or compressed air, the container body can be one or two, the cover can play the role of the valve system of the existing aerosol container, and specifically, the cover has a containing space; the containing space of the cover is provided with a liquid outlet unit having a liquid outlet channel, a nozzle having a spray hole arranged at one side of the cover and communicated with the liquid outlet channel, a nozzle closure arranged at one side of the nozzle, and a control mechanism for controlling the communication between the liquid outlet channel and the spray hole by applying or removing force to the nozzle closure.

[0052] The cover structure of the present application will be described in detail below with reference to the drawings.

[0053] Please refer to Figures 2 to 12 , the cover comprises an upper cover assembly and a lower cover assembly, the lower cover assembly is used for sealingly connecting with the container body, the lower cover assembly comprises a sealing cup 40, the center of the sealing cup 40 is provided with an insertion hole 400, and the edge of the sealing cup 40 can be sealingly connected with the container body; the upper cover assembly can be connected with the sealing cup, the upper cover assembly comprises an upper cover unit, an upper cover body 10 and a valve rod 20 extending below the upper cover body 10; the valve rod 20 has a first liquid conveying channel 1300, the valve rod 20 can pass through the insertion hole 400, and when the nozzle closure without the nozzle is closed, the first liquid conveying channel 1300 is communicated with the spray hole of the nozzle.

[0054] A liquid outlet is arranged at one side of the upper cover body 10, the nozzle 11 is installed in the liquid outlet, and the nozzle closure 12 is assembled in the nozzle, specifically, the nozzle closure 12 comprises a closed cylinder 120 with one end open and a closing thimble 121 extending outside the bottom of the closed cylinder 120, when the closing thimble 121 is inserted into the spray hole 110 of the nozzle, the nozzle 11 can be closed, that is, the communication between the liquid outlet channel and the nozzle can be blocked; the control mechanism can control the position relationship between the nozzle closure 12 and the nozzle 11 by applying or removing force to the nozzle closure 12, so as to control the communication between the liquid outlet channel and the nozzle, compared with the existing aerosol valve system, the liquid outlet channel in the present application is always kept unblocked, the nozzle closure 12 can be pressed by the control mechanism to stably close the nozzle when no drug is given, and the antibacterial effect at the nozzle is realized.

[0055] Specifically, when the control mechanism cancels the force on the nozzle closure 12, the solution in the container body will push the nozzle closure 12 along the liquid outlet channel and be sprayed out of the spray hole 110 of the nozzle 11; that is, the nozzle closure 12 can move towards or away from the nozzle 11, in order to achieve controllable and stable movement of the nozzle closure 12, the nozzle closure 12 is sleeved on one end of the inner plug 13, the inner plug 13 is stably placed in the inside of the upper cover body 11, for example, a containing space 100 is formed in the upper cover body 11, the containing space 100 has a positioning step, the inner plug 13 is assembled in place through the positioning step, and in other embodiments, the inner plug 13 can also be integrally formed with the upper cover body 10; the inner plug 13 is in sealing connection with the nozzle closure 12, and the closure cylinder 120 can slide a certain distance relative to one end of the inner plug 13, that is, a certain elastic interference fit is achieved.

[0056] Please refer to Figure 7 In addition to the liquid delivery channel 1300 and the liquid delivery slit 1100, the inner plug 13 and the containing space 100 of the upper cover body are not allowed to communicate with each other. The liquid delivery slit 1100 is arranged on the inner wall of the containing space 100, the first liquid delivery channel 1300 is in communication with the containing space 100, and only the liquid delivery slit 1100 is in communication with the first liquid delivery channel 1300 when the inner plug 13 is assembled into the containing space 100. In one of the embodiments, the outer side wall of the inner plug 13 is provided with a positioning rib 130, as shown in the drawings, the positioning rib 130 is arranged in the liquid delivery slit 1100, and the positioning rib 130 partially fills the liquid delivery slit 1100 in the depth direction, that is, the positioning rib 130 is arranged to prevent mistakes and does not affect the use of the liquid delivery slit 1100. Figure 10

[0057] Meanwhile, the first liquid delivery gap 1200 is formed between the nozzle closure 12 and the inner wall of the containing space 100; the liquid delivery gap 1200 is in communication with the liquid delivery slit 1100, that is, when the first liquid delivery channel 1300, the liquid delivery slit 1100 and the first liquid delivery gap 1200 constitute the liquid outlet channel, liquid can be sprayed when the liquid outlet channel and the spray hole 110 are in communication; and when the control mechanism applies a pressing force to the nozzle closure 12, the communication between the first liquid delivery gap 1200 and the spray hole 110 is blocked.

[0058] The main point of the application is to keep the liquid outlet channel unobstructed, and the design of opening and closing the liquid outlet is placed at the nozzle, which prevents the nozzle from being contaminated and realizes the control of drug administration. The specific structure of the control mechanism of the application will be described in detail below. Embodiment​

[0059] See also Figures 2 to 7 In this embodiment, the control mechanism applies pressure or cancels the force on the nozzle closure 12 by its own rotational movement. Specifically, the control mechanism includes a pressure rod 14, and the pressure rod 14 has a rotation axis 140. The pressure rod 14 can rotate relative to the gland body 10 via the rotation axis 140. Figure 5 As shown, a plate body extends from the inner wall of the upper cover body 10, and a rotating hole 101 is opened on the plate body. The rotating shaft 140 of the pressure rod 14 rotates in the rotating hole 101; at the same time, a pressing portion 141 is provided at the end of the pressure rod 14 away from the nozzle closure 12. When a force is applied to the pressing portion 141, the pressure rod 14 abuts against one end of the nozzle closure 12, that is, it makes a circular motion with the center point of the rotating shaft 140 as the center, and moves away from the nozzle closure 12.

[0060] The plate extending from the inner wall of the upper cover body 10 can be on the upper wall of the upper cover body 10 or on the side wall. Of course, the plate can also be set at other positions, such as Figure 4 As shown, the plate can also be arranged on the cover unit, and at the same time, Figure 2 In the perspective, the pressure rod 14 can rotate within the current viewing plane, or can rotate perpendicular to the current viewing plane. Any rotation method that can move the pressure rod 14 away from the nozzle closure 12 is within the protection scope of the present invention.

[0061] Furthermore, a rotation stop is provided within the accommodation space. The rotation stop is used to limit the rotation angle of the pressure rod 14. The rotation stop comprises a first stop unit provided on the pressure rod and a second stop unit provided within the accommodation cavity of the pressure cover. Specifically, when the injection hole 110 of the nozzle 11 is to be closed from an open state, when a pressure force is applied to the pressing portion 141 of the pressure rod, causing the pressure rod to move in a circular motion near one end of the nozzle seal 12, the rotation stop can rotate the pressure rod to a specific position to abut against the nozzle seal 12 without excessive rotation. Specifically, when the control mechanism applies a pressure force to the nozzle seal, the second stop unit can restrict the first stop unit from further movement.

[0062] like Figure 2 As shown, in one embodiment, the first stop unit is a limiting plane opened on the pressure rod 14; the second stop unit is a support rod 102 arranged in the accommodating space. When the control mechanism applies pressure to the nozzle closure, the limiting plane fits with the upper end surface of the support rod. At this time, it means that the pressure rod has pressed the nozzle closure against the nozzle.

[0063] In other embodiments, the first and second stop units can also be implemented in other structures, such as clamping the edge of the pressing part of the pressing rod in the limiting slot correspondingly formed in the pressing cover to limit the rotation of the pressing rod. Embodiments

[0064] In the embodiment, as shown in Figures 8 to 12 The control mechanism applies or removes the force by horizontal push-pull movement relative to the nozzle closure 12. Specifically, the control mechanism comprises a pressing rod 14', one end of which is provided with a locking spring 140', and a locking limiting slot 101' is arranged in the pressing cover. When in the non-working state, the locking spring 140' is arranged in the locking limiting slot 101', thereby limiting the movement of the pressing rod 14 and making it abut against the nozzle closure 12. When the locking spring 140' is pressed to be separated from the locking limiting slot 101', the pressing rod 14' can be pulled to move away from the nozzle closure 12.

[0065] When the locking spring 140' is separated from the locking limiting slot 101', the pressing rod 14' can be directly manually pulled out, or a sliding guide 102' can be arranged on one side of the locking limiting slot 101', as shown in Figure 11 When the locking spring 140' is pressed, it slides along the sliding guide 102', which is an inclined surface. When the locking spring 140' slides a certain distance, it can also be limited in other limiting slots without falling off.

[0066] Based on the main improvement point of the present application, the valve rod 20 can directly extend into the container body, and sealing is achieved at the insertion hole. In addition, the present application can also be simply improved on the existing valve system to achieve the effect intended by the present application. Please refer to Figure 1 and Figure 7 The upper cover assembly further comprises a cover seat body 30, which can be integrally formed with the upper cover body 10, or can be separately formed to reduce the forming process. The sealing cup 40 is clamped with the cover seat body 30. During assembly, the sealing cup 40 and the valve body 50 are sealed and assembled with the container body through the corresponding assembly process, and then the assembly of the upper cover assembly and the sealing cup 40 is realized through the cover seat body 30.

[0067] The sealing cup 40 comprises a first side wall 401 extending in the circumferential and axial directions, a sealing cup flange 402 extending radially outward and downward from the upper end face of the first side wall 401, a sealing cup guide wall 403 extending radially upward and obliquely from the lower end face of the first side wall 402, a second side wall 404 extending axially from the end face of the sealing cup guide wall 403, and a sealing cup ring wall 405 extending radially from the upper end face of the second side wall 404. The center of the cup ring wall; a plurality of inner protrusions 410 are radially inwardly formed on the second sidewall 404, and a plurality of airtight grooves 500 are correspondingly formed on the outer peripheral wall of the valve body 50. The inner protrusions 410 are disposed within the airtight grooves 500, thereby achieving a reliable connection between the valve body 50 and the sealing cup 40; an inner seal 70 is disposed between the upper end surface of the valve body 50 and the inner wall of the sealing cup ring wall 405, and an outer seal 80 is disposed below the connection between the sealing cup flange and the first sidewall. One end of the valve stem 20 extends through the insertion hole 400 and the inner seal into the second infusion channel 1400 of the valve body 50.

[0068] like Figure 7 As shown, a valve seat 60 is provided in the second infusion channel 1400, and the valve seat 60 has a valve cavity 600. The valve stem 20 is inserted into the valve cavity 60, and a second infusion gap 1500 is formed between the valve stem 20 and the inner wall of the valve cavity 600, between the upper end surface of the valve seat 60 and the lower surface of the inner seal 70, and between the outer wall of the valve seat 60 and the inner wall of the second infusion channel 1400; the second infusion channel 1400, the second infusion gap 1500, the first infusion channel 1300, the infusion narrow channel 1100 and the first infusion gap 1200 constitute the liquid outlet channel.

[0069] An adjusting elastic member 61 is provided below the valve seat. When the upper cover body 10 is separated from the cover seat body 30, the valve seat 60 closes the insertion hole under the action of the adjusting elastic member 61. When the upper cover body 10 is assembled with the cover seat body 30, the valve stem 20 extends through the insertion hole 400 into the valve cavity 600. The lower end of the valve stem 20 can exert a certain force on the bottom of the valve cavity 600, causing the adjusting elastic member 61 to be compressed, thereby opening a second infusion gap between the upper end surface of the valve seat 600 and the inner seal 70, thereby maintaining the unobstructed flow of the liquid outlet channel. Of course, the lower outlet of the first infusion channel of the valve stem 20 can be provided on the side wall of its lower end, so that when the lower end of the valve stem 20 abuts against the bottom of the valve cavity 600, it will not block the first infusion channel 1300.

[0070] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
