Abstract
The present invention provides a valve cup (10) for use with a container (30) for dispensing a fluid medium stored under pressure. The valve cup (10) supports a valve (50) and seals an opening (32) of the container (30) and is formed from a semi-crystalline polyester. The present invention also provides a container (30), wherein at least a part of the container (30) surrounding an opening (32) is formed from a semi-crystal-line polyester. A further valve cup (10) is formed from a metal or rigid material and further includes a polyester lining (70). Dispensing systems (1) including the above containers (30) and valve cups (10) are provided, wherein welding is facilitated between the container (30) and valve cups (10).
