Sealant cartridges and method of making the same.

摘要

Sealant cartridges which have non-slip off labels can be made by heat-shrinking a resin film tube (17) on a cartridge which has a cylindrical cartridge body (11) with an outside diameter which increases toward the extrusion part (14) end and an inside diameter which remains constant along the length. The heat-shrunk resin film end extending toward the extrusion part covers the outer margin of the shoulder (18).
