An encapsulated transformer includes a transformer coil assembly, a rigid core insert having an upstanding portion positioned within the hollow interior of the core and a base portion on which the core rests, and a thermoplastic rubber jacket that completely surrounds the transformer coil assembly and is bonded to the base portion of the core insert to provide a completely waterproof encapsulated transformer which is impervious to liquid and gasses that could be detrimental to the performance of the transformer. A method for producing such an encapsulated transformer includes placing a rigid core insert in a mold cavity of a mold, and positioning a transformer coil assembly in the mold cavity so that the transformer coil assembly rests on the core insert. Thermoplastic rubber is then injected into the mold cavity to completely encapsulate the transformer coil assembly in a jacket of thermoplastic rubber. During the injection step, gas in the mold cavity is vented through a vent space provided in the bottom surface of the mold cavity. A mold for encapsulating a transformer coil assembly in thermoplastic rubber includes a bottom mold portion having a mold cavity, an upstanding pin disposed within the mold cavity, a mold cover for closing the mold cavity, and a vent space positioned in the bottom surface of the mold cavity for venting gas within the mold cavity to the exterior of the mold during the injection of thermoplastic rubber into the mold cavity.

The method of claim 5, wherein the chimney core section of the third mold section includes opening-forming structure that engages one or more inner surface areas of the spout member end wall so as to form one or more openings in the spout member end wall. 7. The method of claim 1, wherein the first and second mold cavities are configured so as to form movement-limiting structure between the chimney member and the spout member. 8. The method of claim 7, wherein the first and second mold cavities are configured to form mating helical engagement structure between the spout member and the chimney member, for providing translational inward and outward movement of the spout member upon rotation of the spout member relative to the chimney member, and wherein the movement-limiting structure comprises stop member and recess structure associated with the spout member and the chimney member, wherein engagement of the stop member with at least one end of the recess is operable to limit rotational movement of the spout member relative to the chimney member, to thereby prevent further rotational movement of the spout member relative to the chimney member and resultant translational movement of the spout member relative to the chimney member. 9. The method of claim 8, wherein the stop member is formed on the side wall of the spout member and wherein the recess is defined by a base section of the chimney member, and wherein the chimney member further includes a chimney section extending from the base section and wherein the mating helical engagement structure is located between the side wall of the spout member and the chimney section of the chimney member. 10. The method of claim 1, wherein the spout member is movable relative to the chimney member for movement between an open position and a closed position, wherein the spout member and the chimney member are formed such that the spout member is initially in its closed position when the spout member and the chimney member are formed, and further comprising the step of forming a frangible tamper evident member integrally with one of the chimney member and the spout member which is engageable with the spout member for maintaining the spout member in its initial closed position, wherein the tamper evident member is removable so as to enable the spout member to be moved to its open position and to provide a visual indication as to movement of the spout member away from its initial closed position. 11. A method of forming a two-piece container closure assembly having a chimney member and a spout member, comprising the steps of: positioning first and second mold sections together, wherein the first and second mold sections cooperate to define a first cavity having a side wall portion and an end wall portion; injecting moldable material into the first cavity to form a spout member having an end wal l and a side wall which cooperate to form an internal cavity, wherein the first and second mold sections are configured to form an opening in at least one of the side wall portion and the end wall portion of the spout member; removing the second mold section while maintaining the spout member in engagement with the first mold section; positioning a third mold section in engagement with the first mold section, wherein the first and third mold sections cooperate with the spout member to define a second cavity having a base portion and a chimney portion, wherein the chimney portion of the second cavity is defined in part by inner surface areas of the spout member end wall and side wall; and injecting moldable material into the second cavity to form a chimney member having a base section and a chimney section, wherein the second cavity is configured to form an opening in the chimney section when the moldable material is injected into the second cavity; wherein the second cavity is further configured such that, during formation of the chimney member, the opening in the chimney section is closed by the material of the spout member and the opening in the spout member is closed by the material of the chimney member. 12.
