Abstract: The invention is a round, flexible, hollow tubular insert to be affixed in a central position within pressurized sprinkler pipes, water pipes and water mains. The insert will be employed to prevent sprinkler pipe, water pipe and water main ruptures due to the water within the sprinkler pipe, water pipe or water main freezing. The insert is constructed of a thin-walled, flexible material that is capable of being deformed (e.g. compressed), thereby absorbing the expansion pressures exerted by the water in a frozen state (i.e., ice). The insert is constructed with guides to maintain a position in the center of sprinkler pipes, water pipes and water mains to absorb the radial freezing of water. By such absorption, the outer sprinkler pipe, water pipe or water main itself will not be over-pressurized, thereby avoiding the possibility of a rupture. Upon the thawing of the frozen water, the flexible, hollow, tubular insert will return to its original shape.

Abstract: A toothbrush is made of molded plastic and has a handle which is largely hollow with an open wall and transverse ribs providing structural rigidity and defining compartments. Pre-packaged dentifrice packages are received in the compartments and have peel-off covers secured to the packages and severable from each other and the container to permit individual removal of packages from the handle while, at the same time, preserving the integrity of the remaining packages and the sealing of the compartments in which the packages are received.
