| 摘要 |
<p>This invention is concerned with the destruction of filled but rejected aerosol containers (5) during manufacture thereof. Apparatus is provided with a support for such containers, preferably a tube (1) having a slit therein adjacent which a rejected container is held. A cutter (4) such as a rotary blade is arranged to pass through the slit and pierces the container whereupon the contents of the container under pressure pass through a duct (3) into a collecting tank (2). Propellant gas is conveniently removed by an extractor whilst the product collects in the tank. A pump (14) energized through a float switch (15) for example pumps the product out when it reaches a predetermined level. Advantageously, the propellant gas and product are not released into the atmosphere and therefore the process and apparatus are environmentally friendly, whilst the propellant gas and product are reusable.</p> |
