Abstract: A method and apparatus for forming a soap bar from remnants of used soap bars. A molding base defining an internal molding cavity is provided with a pivotal closure also defining an internal die cavity. A forming die is movably supported by the closure and is movable from a retracted position out of the molding cavity to an extended position within said molding cavity where the forming die applies mechanical pressure to the soap fragments. The forming die is receivable within the die cavity at its retracted position and has a concave die surface of a configuration for forming a portion of the soap bar. A die actuator extends through the closure and may be provided with a spring for retraction of the die or for urging the die in a direction for continuous application of molding force to the forming die for a sufficient period of time for adhering and forming the soap bar fragments so as to define a resulting soap bar for subsequent conventional use.

Abstract: Method and system are disclosed for making a hollow-shaped body from molten resin wherein the method includes the step of cutting a hole through the resin after it is cooled and into a fluid aperture formed during a fluid injection step which distributes the molten resin over the interior surfaces of a mold of the system. The fluid aperture is in communication with the interior of the resulting hollow-shaped body and is preferably located in the runner or sprue of the mold. The fluid is preferably a gas, such as nitrogen. In each of the disclosed embodiments of the invention, a cutting member is located in the mold and has a surface which at least partially defines a resin flow path in the mold. Cutting is accomplished by moving the cutting member in a controlled fashion between a molding position and a relieving position so that the cutting member applies a cutting force to cut the hole. The cutting member includes a fluid-relieving aperture formed therein.
