- I have a question, patent for a novel syringe device says:
A sealing label or heat stake may be disposed about the area of interface to
form a protective seal for those parts of barrel assembly which must be
maintained in a sterile and tamper proof environment.
I have a problem with that "heat stake". Basically, it is about fixing two
plastic parts together. Is it a heated device specifically designed for its
purpose, which melts the interface and thus creates the seal?
