Description

Technical Field

[0001] The invention relates to the field of pharmaceutical product packaging, in particular to a novel aerosol container. Background Art

[0002] Aerosol is a commonly used medical device that can spray the liquid in the container into mist with the help of the pressure of the propellant for the treatment of patients. Existing aerosol delivery devices usually include a container and a valve system configured above the container. The aerosol valve is a key component of the aerosol and plays a very important role in the function of the aerosol. It is not only related to the product sealing, but also to the spraying effect and the stability of the product.

[0003] like Figure 1 As shown, the aerosol valve usually consists of a push button 1', a sealing cup 2', an outer sealing ring 3', an inner sealing ring 4', a valve stem 5', a valve body 6', a spring 7', a liquid guide tube 8' and other parts. In the non-working state, the valve is in a closed state under the action of the spring 7', and in the working state, when the push button 1' is pressed, the valve stem 5' moves downward, and the valve stem spray hole 9' leaves the sealing ring and is in an open state, so that the stem body and the valve body mixing chamber are connected, and under the pressure of the propellant, the contents are sprayed through the conduit, the valve body spray hole, the mixing chamber, and then through the valve body spray hole, the valve stem, and finally from the button spray hole. When the spring pushes the valve stem back, the valve stem spray hole is sealed, and the valve is in a closed state again. Among them, the inner sealing ring 4' is used to close the valve stem 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 achieve the seal between the sealing cup and the container; the push button is usually installed above the valve stem, and there is no strict seal between the push button and the sealing cup, so that the valve stem is partially exposed to the air. When the push button pushes the valve stem downward, the part of the valve stem exposed to the air will pass through the inner sealing ring and mix with the liquid in the valve body, causing pollution to the liquid to a certain extent.

[0004] In addition, after delivering the liquid medicine, the button spray hole of the existing aerosol valve is always in an open state, so that the discharged liquid medicine may remain in the discharge port or the injection channel and be exposed to the outside for a long time, resulting in contamination, deterioration and other unsanitary conditions.

[0052] The technical solution protected by the present invention is described in detail below with reference to the accompanying drawings.

[0053] like Figure 1 As shown, the liquid outlet unit in the existing aerosol valve system is composed of a valve stem 5' and an infusion channel in the valve body 6', and the push button 1' controls the opening and closing of the infusion channel through the movement of the pump; in order to avoid the possibility of residual solution at the injection hole or the contamination of the solution remaining in the infusion channel through the injection hole, a nozzle seal is usually provided at the nozzle. For other non-aerosol pumping valve systems, since there is no pressure difference in the container, when the pump head is pressed, the pressure in the container is greater than the pressure outside the container, and the pumped solution can push the nozzle closure configured in the nozzle to open the nozzle. After the liquid is discharged, the spring is used to reset the nozzle closure to the nozzle to continue sealing. However, for aerosols, due to the high pressure in the bottle, this anti-bacterial method is not suitable.

[0054] The present invention proposes a novel aerosol container, comprising a container body and a gland arranged at an opening of the container body, wherein the container body is used to store an aerosol solution and a propellant or compressed air, the container body may be a single element or a dual element, and the gland can play the role of a valve system of an existing aerosol container, specifically, the gland has a containing space; the containing space of the gland is provided with: a liquid outlet unit having a liquid outlet channel, a nozzle having a spray hole connected to the liquid outlet channel and arranged on one side of the gland, a nozzle closure arranged on one side of the nozzle, and a control mechanism for controlling the connection between the spray hole and the liquid outlet channel by applying or removing a force on the nozzle closure.

[0055] The gland structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] Please refer to Figures 2 to 12 The pressure cover includes an upper cover assembly and a lower cover assembly, the lower cover assembly is used to be sealed with the container body, the lower cover assembly includes a sealing cup 40, the center of the sealing cup 40 is provided with an insertion hole 400, and its edge can be sealed with the container body; and the upper cover assembly can be connected with the sealing cup, the upper cover assembly includes an upper cover unit, the upper cover unit upper cover body 10 and a valve stem 20 extending below the upper cover body 10; the valve stem 20 has a first infusion channel 1300, the valve stem 20 can pass through the insertion hole 400, and when the nozzle closure member of the nozzle is not closed, the first infusion channel 1300 is connected with the injection hole of the nozzle.

[0057] A liquid outlet is provided on 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 includes a closing cylinder 120 with an opening at one end and a closing ejector pin 121 extending outside the bottom of the closing cylinder 120. When the closing ejector pin 121 is inserted into the injection hole 110 of the nozzle, the nozzle 11 can be closed, that is, the connection between the liquid outlet channel and the nozzle can be blocked; the control mechanism can control the positional relationship between the nozzle closure member and the nozzle 11 by applying pressure to the nozzle closure member 12 or canceling the force, so as to control the connection between the liquid outlet channel and the nozzle. Compared with the existing aerosol valve system, the liquid outlet channel in the present invention is always kept in a smooth state. The control mechanism can control the drug administration and apply pressure to the nozzle closure member 12 when no drug administration is performed to stably close the nozzle, thereby achieving a bacteria-blocking effect at the nozzle.

[0058] Specifically, when the control mechanism cancels the force applied to the nozzle closure 12, the solution in the container body will push the nozzle closure 12 away along the liquid outlet channel and be sprayed out through the injection hole 110 of the nozzle 11; that is, the nozzle closure 12 can move toward 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, and the inner plug 13 is stably placed inside the upper cover body 11, such as a accommodating space 100 is formed in the upper cover body 11, and a positioning step is provided in the accommodating space 100, and the inner plug 13 is assembled into place through the positioning step. In other embodiments, the inner plug 13 can also be integrally formed with the upper cover body 10; the inner plug 13 is sealed and connected to the nozzle closure 12, and the closed cylinder 120 can also slide a certain distance relative to one end of the inner plug 13, that is, a certain elastic interference fit is achieved.

[0059] See also Figure 7 , and no solution is allowed to flow between the inner plug 13 and the receiving space 100 of the upper cover body except for the narrow infusion channel 1100 connecting the first infusion channel 1300 and the injection hole 110. The narrow infusion channel 1100 is opened on the inner wall of the receiving space 100, and the first infusion channel 1300 is connected to the receiving space 100. When the inner plug 13 is assembled into the receiving space 100, only the narrow infusion channel 1100 is connected to the first infusion channel 1300. In one embodiment, the outer wall of the inner plug 13 is convexly provided with a positioning rib 130, such as Fig.10 As shown, the positioning ribs 130 are arranged in the infusion narrow channel 1100, and the positioning ribs 130 partially fill the infusion narrow channel 1100 in the depth direction, that is, through the arrangement of the positioning ribs 130, while preventing mistakes, the use of the infusion narrow channel 1100 is not affected.

[0060] At the same time, a first infusion gap 1200 is formed between the nozzle closure 12 and the inner wall of the receiving space 100; the infusion gap 1200 is connected with the infusion narrow channel 1100, that is, when the first infusion channel 1300, the infusion narrow channel 1100, and the first infusion gap 1200 constitute a liquid outlet channel, when the liquid outlet channel and the injection hole 110 are connected, liquid can be sprayed out; and when the control mechanism applies pressure to the nozzle closure 12, the connection between the first infusion gap 1200 and the injection hole 110 is blocked.

[0061] The invention of the present invention is mainly to keep the liquid outlet channel unobstructed, and to place the design of opening and closing the liquid outlet at the nozzle, thereby preventing the nozzle from being contaminated and achieving drug administration control. The specific structure of the control mechanism of the present invention is first described in detail below.

[0062] Embodiment 1

[0063] 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 through 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.

[0064] 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 body 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.

[0065] Furthermore, a rotation stopper is also provided in the accommodation space, and the rotation stopper is used to limit the rotation angle of the pressure rod 14, and the rotation stopper includes a first stopper unit provided on the pressure rod and a second stopper unit provided in the accommodation cavity of the pressure cover; that is, when the injection hole 110 of the nozzle 11 is to be changed from an open state to a closed state, when a pressure force is applied to the pressing portion 141 of the pressure rod to make the pressure rod move along a circle close to one end of the nozzle closure 12, the rotation stopper can make the pressure rod rotate to a specific position to abut against the nozzle closure 12 without excessive rotation. That is, when the control mechanism applies a pressure force to the nozzle closure, the second stopper unit can limit the first stopper unit from continuing to move.

[0066] 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.

[0067] In other embodiments, the first stop unit and the second stop unit may also be implemented by other structures, such as clamping the edge of the pressing portion of the pressure rod in a corresponding limiting groove on the pressure cover to limit the rotation of the pressure rod.

[0068] Embodiment 2

[0069] In this embodiment, Figures 8 to 12 As shown, the control mechanism applies pressure or cancels the force by performing horizontal push-pull movement relative to the nozzle closure 12. Specifically, the control mechanism includes a pressure rod 14', one end of which is provided with a locking spring 140', and a locking limit groove 101' is provided in the pressure cover. When in a non-working state, the locking spring 140' is arranged in the locking limit groove 101', thereby limiting the movement of the pressure rod 14 and making it abut against the nozzle closure 12; and when a pressure force is applied to the locking spring 140' to make it disengage from the locking limit groove 101', the pressure rod 14' can be pulled to move in a direction away from the nozzle closure 12.

[0070] When the locking spring piece 140' is separated from the locking limit slot 101', the pressing rod 14' can be directly pulled manually, or a sliding guide 102' can be provided on one side of the locking limit slot 101'. Fig.11 As shown, when a force is applied to the locking spring piece 140', it slides along the sliding guide 102'. The sliding guide 102' is an inclined surface. After the locking spring piece 140' slides a certain distance, it can also be limited in other limiting grooves without falling.

[0071] Based on the main improvement of the present invention, the valve stem 20 can be directly inserted into the container body, and the sealing is done at the insertion hole. In addition, the present invention can also achieve the desired effect of the present invention by simply improving the existing valve system. Figure 1 and Figure 7 The upper cover assembly also includes a cover seat body 30, and the cover seat body 30 can be integrally formed with the upper cover body 10, or can be formed separately to reduce the molding process; the sealing cup 40 is snap-connected 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 upper cover assembly and the sealing cup 40 are assembled through the cover seat body 30.

[0072] 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 insertion hole 400 is formed in the sealing cup. The center of the cup ring wall; a plurality of inner protrusions 410 are radially inwardly protruded on the second side wall 404, and a plurality of air-avoiding grooves 500 are correspondingly opened on the outer peripheral wall of the valve body 50, and the inner protrusions 410 are arranged in the air-avoiding grooves 500, so as to realize the reliable connection between the valve body 50 and the sealing cup 40; an inner seal 70 is arranged 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 arranged on the lower side of the connection between the sealing cup flange and the first side wall. One end of the valve stem 20 passes through the insertion hole 400 and the inner seal to extend into the second infusion channel 1400 of the valve body 50.

[0073] 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.

[0074] 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 passes through the insertion hole 400 and extends 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 to compress the adjusting elastic member 61, thereby opening the second infusion gap between the upper end surface of the valve seat 600 and the inner sealing member 70, thereby keeping the liquid outlet channel unobstructed. Of course, the lower outlet of the first infusion channel of the valve stem 20 can be opened 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, the first infusion channel 1300 will not be blocked.

[0075] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
