Embodiment Construction

[0023] The present invention relates to an improved method of coating the inner surface of a container, especially a container for storing pharmaceutical preparations, to prevent the pharmaceutical preparations stored in the container from adhering or chemically reacting with the surface of the container, so that the pharmaceutical preparations can be produced in a precise manner. Measured doses are dispensed. Additionally, the present invention relates to an improved method of coating the interior surfaces of containers for storing pharmaceutical formulations that are substantially free of leachable organic compounds that can react with the pharmaceutical formulations stored in the container.

[0024] In particular, the present invention generally relates to a method of coating at least one surface of a container for storing a drug or other ingestible non-pharmaceutical product, the method comprising the steps of:

[0025] a) cleaning at least one surface of the container wit...

Abstract

The invention discloses a method for cleaning and coating at least one surface of a container used for storing medicine or other ingestible non-medicinal products. The method comprises the step of adopting a water-based cleaning combination together with coating-containing water-based crosslinked acrylic resin. The cleaning and coating technologies based on the process conform to the current environmental regulations and workplace safety standards, and the process includes control over discharge of volatile organic compounds (VOCs). In addition, the concentration of organic compounds which can be separated out is lowered to the actual lowest level. The process can also be used for other base materials, and the process has the requirements that the amount of organic matters which can be separated out is low, and subsequently applied coating has high adhesiveness.

Description

technical field [0001] The present invention relates to a method of cleaning and coating at least one surface of a container for holding a medicament, using a unique composition of an aqueous cleaning agent and a special aqueous coating composition, wherein the aqueous cleaning agent is used to increase surface wetting properties and The aqueous coating composition is designed to significantly reduce leachable organics and provide effective drug barrier and low sticking tendency. Background technique [0002] Medications for the treatment of respiratory and nasal conditions are usually administered orally or nasally as aerosol compositions. One widely used method of formulating such aerosol drug compositions involves preparing the drug as a suspension or solution in finely divided powder form in a liquefied gas called a propellant. This suspension is stored in a sealed container (or tank) that can withstand pressure to keep the propellant liquid. The formulation can then b...
