摘要:
A method of making a dispensing device for dispensing a substance comprises a step of providing a mold having a mold space for receiving a solidifyable material. The method further comprises steps of providing a valve member having a first portion formed between first and second areas of an outer surface of the valve member; placing the valve member into the mold space such that at the first area is isolated from the mold space and at least part of the second area is within the mold space; displacing the first portion at least partially relative to another portion of the valve member; and solidifying the material in the mold space and thereby fixing the displaced first portion in place. The method preferably helps minimizing manufacturing costs and maximizing shelf life of a device filled with substance.
