    摘要: Capless retractable sealed marking instruments have a single piece elastomeric seal incorporated in a marker casing. The seal includes an annular rim and a concave disk with cooperative sealing disk halves having lateral sealing surfaces which are moved out of contact by a linearly advanced marker nib to open the seal for extension of the marker nib. The concave configuration of the disk provides maximum sealing force between the lateral sealing surfaces of the disk halves. Retraction of the marker nib draws the disk halves back into the concave sealed configuration to protect the marker nib and cartridge from atmospheric degradation.
