A rapid packaging aerosol quantitative valve

Abstract

The invention discloses a rapid-packaging aerosol metering valve, comprising a metering valve, wherein the metering valve can quantitatively spray medicine, and adopts the existing principle which will not be described here. A sealing ring is assembled on the valve cover of the metering valve, wherein the sealing ring is in the shape of a circular ring, wherein one end of the sealing ring is a plane cross section, and the other end is a conical cross section, wherein one end of the conical surface faces downward, and the sealing ring is coaxially sleeved on the valve cover of the metering valve, wherein the valve cover of the metering valve is provided with a pre-assembly surface, and one end of the sealing ring is sleeved on one end of the pre-assembly surface on the valve cover of the valve. During packaging, the sealing ring is pressed downward, so that the valve cover of the valve is deformed and contracted at a position different from the pre-assembly surface, and the inner diameter becomes smaller, so that the aerosol bottle with an elastic sealing device is tightly embraced to be sealed, thereby achieving a rapid sealing effect.

Description

Technical Field

[0001] The invention relates to an aerosol quantitative valve, in particular to a rapid packaging aerosol quantitative valve. Background Art

[0002] As air pollution becomes increasingly serious, the number of patients suffering from respiratory diseases at home and abroad is increasing, and respiratory drugs are gradually entering the field of vision of pharmaceutical companies, doctors and patients. Asthma and chronic obstructive pulmonary disease (COPD) are the two most serious respiratory diseases that affect patients. According to statistics from the World Health Organization in 2013, respiratory diseases have jumped to the third highest mortality rate, with a mortality rate of 14.09%. However, as new technologies have made great progress in lung inhalation drug delivery, the majority of patients also prefer to use inhalation drug delivery to treat lung and bronchial diseases.

[0003] When treating asthma, using an aerosol valve to spray the medicine into the trachea is the most effective treatment method. Because the inhalation aerosol medicine bottle occupies an extremely important position in ensuring the production quality of inhalation aerosol medicines, and the aerosol metering valve is the most important component of the aerosol medicine bottle, the packaging of the aerosol metering valve has always been a major difficulty. Traditional aerosol metering valves are packaged using special sealing machines, which require cumbersome measurements and calculations to calibrate the position of the valve cover grip and the compression of the sealing gasket, and then use special gripping equipment for packaging. The present invention designs a fast-packaging aerosol metering valve, which only needs to press down the sealing ring to break the valve cover to deform and shrink, and the inner diameter becomes smaller, and the aerosol bottle with an elastomeric sealing device is tightly held to seal it, thereby achieving the purpose of rapid packaging. No complicated measurements and calculations are required, and no special gripping equipment is required. Summary of the invention

[0004] The main purpose of the present invention is to provide a rapid packaging aerosol metered dose valve

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: a rapid encapsulation aerosol metering valve, including a metering valve, the metering valve can quantitatively spray medicine, the existing principle is not described here, a sealing ring is installed on the valve cover of the metering valve, the sealing ring is in the shape of a circular ring, one end of the sealing ring is a plane cross-section, the other end is a conical cross-section, one end of the conical surface faces downward, the sealing ring is coaxially sleeved on the valve cover of the metering valve, the valve cover of the metering valve has a pre-assembled surface, and one end of the sealing ring is sleeved on one end of the pre-assembled surface on the valve cover of the valve.

[0006] Preferably, it comprises a sealing ring sleeved on the pre-assembly surface on the valve cover, the sealing ring is coaxially sleeved on the valve cover, and the inner diameter of the sealing ring is consistent with the outer diameter of the pre-assembly surface on the valve cover.

[0007] Preferably, the sealing ring can be pressed downward, and when pressed downward, the sealing ring forces the valve cover to deform and shrink, and the diameter becomes smaller.

[0008] Preferably, a pre-assembly surface for fitting a sealing ring is provided on the valve cover.

[0009] Preferably, the sealing ring is made of stainless steel, coated steel or iron, high-strength engineering material, etc.

[0010] Preferably, the outer diameter of the sealing ring is 21.15 mm.

[0011] Preferably, the outer diameter of the sealing ring is 20 mm.

[0012] Preferably, the outer diameter of the sealing ring is 23.2 mm.

[0013] Preferably, the thickness of the sealing ring is 0.5 mm, 1 mm, 2 mm, 3 mm, etc.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The aerosol metering valve only needs to press down the sealing ring to deform and shrink the valve cover, reduce the inner diameter, and hold the aerosol bottle with the elastic sealing device tightly to seal it, so as to achieve the purpose of rapid packaging. No complicated measurement and calculation is required, and no special gripping equipment is required. BRIEF DESCRIPTION OF THE DRAWINGS
