The present invention relates to a cartridge casing for firearm ammunition and to a method of manufacturing such casing. The casing () comprises an elongate interior cavity () and extends along a longitudinal axis (). The cavity () is open at the top end of the casing () and is defined radially by a circumferentially extending sidewall () formed by an elongate tubular portion and at the bottom by a bottom wall () which is connected to an axial end of the tubular portion and comprises a bore (). The casing () further comprises in a lateral outer surface an annular projection () located proximate the bottom end of the casing () and extending circumferentially in a plane perpendicular to the longitudinal axis () of the casing (). The casing () comprises an elongate tubular sleeve component () open at both axial ends and a separate bottom component () fixedly secured to the sleeve component (). The tubular portion is formed by the sleeve component (), and the bottom wall () is formed at least in part by the bottom component (). The bottom component () comprises a lower axial end surface (), an opposite upper axial end surface () and a circumferentially extending lateral outer surface on which the annular projection () is arranged. The casing () may be manufactured by providing the bottom component () and the sleeve component () and fixedly securing the sleeve component () to the bottom component ().

Cartridge casing and method of manufacturing a cartridge casing

A method of cleaning and coating at least one surface of a container for storing a medicament or other ingestible non-pharmaceutical product, the method comprising the steps of using a water-based cleaning composition in conjunction with a water-based crosslinked acrylic resin containing coating material. The process makes the cleaning and coating technology consistent with present environmental regulations and workplace safety requirements, including control of emissions of volatile organic compounds (VOCs). Further, the concentration of extractible organic compounds has been reduced to the lowest practical level. The process is also applicable to other substrates where it is desired to have low-extractable organics and high adhesion of the subsequently applied coating.
