ABSTRACT:
A valve device that is incorporated into the cap used on plastic bottles, which allow the bottles to receive the injection of gaseous pressure so that the walls of the plastic bottles become firm and rigid, which maximizes the bottles floatation potential. This allow the bottles to be handled and stored easily. These bottles have uses for many types of floatation needs, such as buoys, rafts, etc. The bottles are particularly useful as floatation devices in the sport of fishing, with the addition of fishing lines and hooks.
