A method of making a carburetor float by first creating a homogeneous mixture of gas and polymer in a plastic injection machine. The gas/polymer mixture is injected into a tool having a mold cavity. A moveable portion of the mold cavity allows the gas/polymer mixture to expand in that area thus forming a foamed portion of the finished float. The portion of the mold that is stationary does not allow the gas/polymer mixture to foam and thus forms a portion of the finished float with a higher density that the foamed portion. The result is a float made of the homogeneous mixture with two differing densities in two different portion of the float.

Rounded safety closure

A dispensing tap for beverages that comprises an actuator and a valve housing. A conical spring washer is joined and/or sealed to an actuator base to form the actuator. The actuator is then inserted into the valve housing to form the dispensing tap for attachment to a container containing a liquid. In use, a force is exerted on the conical spring washer to actuate the actuator base within the valve housing and thereby create an opening and/or passageway in the dispensing tap. Once opened and as the force is maintained, the liquid in the container can flow through the opening or passageway for dispensing the liquid out the dispensing tap. Upon releasing the force, the conical spring washer returns back to its original position. This movement of the conical spring washer causes the actuator base to move in the reverse direction within the valve housing thereby closing the opening and/or eliminating the passageway in the dispensing tap. The resultant seal of the actuator base to the valve housing prevents any further liquid from being dispensed from the container.

Container closure

A staged, sequentially separated injection mold () for forming a container spout () having a peripheral flange (), a generally cylindrical sidewall (), a removable panel () fixed within the sidewall, and a pull ring () connected to the removable panel. The mold includes a base (), and a first element () coupled to the base including a gate (). A core plate () movable with respect to the base, and a core element () confronting the first mold element. A sleeve () surrounds the core element having a channel () to define the pull ring. The sleeve moves with respect to the core element to permit release of a molded pull ring. A stripper ring () surrounds the sleeve with an edge () positioned contiguous to the sleeve outward facing surface, the stripper ring being movable along the sleeve.
