Abstract
Improvements in the manufacture of ampoules, applicable to capsules of garland-bulbs, to be made in rotating machines, of the type used to manufacture injectables, characterized by the fact that the tube is stretched at both ends to produce in the center the body of the bulb, and then a lug is made at only one end to produce the strangulation through which the vacuum will be made; next the end is opened, where only a lug has been produced, and the filaments are introduced, then closing said end in a watertight manner by heating and pressing and finally the other end of the tube is opened and attached to the end to a Vacuum producing installation, to realize this, finally heating the throttling to realize in it a welding that closes the body of the bulb, which is thus constituted.
