摘要： The present invention is for a method of forming means to remove a seal that has been affixed to a collapsible tube in accordance with the method shown in U.S. Pat. No. 4,938,818. A laminate removal tab is cut integral with the seal when the seal is cut, and then bent out of the way along the tube neck when the seal is welded to the tube mouth. The seal is easily lifted and grasped by the fingers to pull the seal off the mouth.

摘要： The present invention is for a method of forming a seal in a prior art collapsible tube assembled in a prior art manner. A laminate seal is cut, positioned and held, and welded to the dispensing orifice of a rigid plastic head after the head is molded, but before it is assembled to the tube wall. The seal is protected during the welding of the wall to the head by the use of a heat sink.
