Abstract: Container having a container body comprising a bottom, a rim and a lid securing portion located adjacent the rim. A lid includes a lid base sized and configured to secure the lid to the lid securing portion of the container body and a lid door assembly movably mounted to the lid base. The lid door assembly includes a main door that can assume at least a closed position with respect to the lid base and an open position with respect to the lid base, a first side door that can assume at least a closed position with respect to the main door and an open position with respect to the main door, and a second side door that can assume at least a closed position with respect to the main door and an open position with respect to the main door.

Abstract: A composite lined closure for use with a container having a container neck crown includes a top having a periphery and an underside, a skirt depending downward from the periphery, the skirt including an inner surface and a locking bead radially extending inward from the skirt, and a resilient seal liner extending along the underside and along the inner surface above the sealing bead. Preferably, the liner is formed of an elastomeric material. A method of using the composite lined closure is also described.

Abstract: A staged, sequentially separated injection mold (40) for forming a container spout (14) having a peripheral flange (18), a generally cylindrical sidewall (20), a removable panel (30) fixed within the sidewall, and a pull ring (32) connected to the removable panel. The mold includes a base (42), and a first element (44) coupled to the base including a gate (45). A core plate (60) movable with respect to the base, and a core element (62) confronting the first mold element. A sleeve (76) surrounds the core element having a channel (84) 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 (96) surrounds the sleeve with an edge (98) positioned contiguous to the sleeve outward facing surface, the stripper ring being movable along the sleeve.

Abstract: Screw on caps for bottles that have an anti back off feature formed on a hinged tab of the cap engaging detent teeth below the threads on the bottle. The hinge has a unique configuration that enables the tab to snap into and hold a gripping position while avoiding temporary distortion or creep. The detent teeth are particularly suited for use with blow molded bottles and are capable of restraining a cap within a small angle of a fully tightened position to avoid any significant back off and potential leakage. In one embodiment, the anti back off feature is provided in a child resistant cap while in another embodiment this feature is provided in a simpler continuous thread cap.

Abstract: A tamper-indicating closure of integrally molded plastic construction that includes a base wall having a peripheral skirt with an internal thread for affixing the closure to the container finish. A tamper-indicating band is connected to an edge of the skirt by frangible bridges. A stop flange extends from an edge of the band remote from the skirt for abutment with a bead on the container finish to inhibit removal of the closure absent fracture of the frangible means. A plurality of circumferentially spaced openings extend radially through the skirt at a position between the frangible bridges and the internal thread. These openings provide for ingress of cleansing solution during a washing operation after the closure is applied to a container to flush any residue from between the tamper-indicating band and the closure finish.

Abstract: A tamper-indicating closure of integrally molded plastic construction that include a base wall having a peripheral skirt with internal threads for engaging external threads on a container finish. A tamper-indicating band is connected to the edge of the skirt by a plurality of circumferentially spaced integral frangible bridges. A stop flange extends from an edge of the band remote from the skirt for engagement with a bead on the container finish. The stop flange has a circumferentially continuous free edge remote from the band disposed in a plane parallel to the base wall. A plurality of circumferentially spaced openings are disposed in the stop flange adjacent to the band for drainage of liquid from between the closure skirt and the container finish. A plurality of circumferentially spaced gussets in the stop flange are at the free edge of the ring, with each gusset being disposed between an adjacent pair of drainage openings.

Abstract: A vacuum-indicating closure includes a top wall 12 and a skirt 14 depending from the periphery of the skirt with a tamper-evident band 24 formed on the lower edge of the skirt. The top wall has a center deflectable portion 30 formed by a thinned circumferential hinge 32 and the deflectable portion is divided into pie-shaped segments 44 by a plurality of radially-extending thinned hinged 40. The center deflectable portion is moved between a convex position and a concave position with the presence or absence of vacuum within the container to which it is applied.

Abstract: A mold for forming a plastic closure includes a first mold part defining a female cavity and a second mold part defining a male mold cavity surface, with the second mold part including a core having a knock-out pin reciprocated therein and surrounded by a fixed sleeve which cooperate to define a tamper-evident band on the cavity for the closure. Vents are provided for venting the lower edge of the cavity during the ejection-molding process. Also, the knock-out pin has a lubricant pocket formed on the peripheral surface thereof.

Abstract: Apparatus for forming objects from molten material includes a mold frame and a movable mold side having complementary faces that define molding cavities. The mold frame includes a mold housing having an internally heated manifold which has a molten plastic distribution channel system for conducting molten plastic to injection nozzle passageways, each having a restricted discharge nozzle that discharges the plastic into a molding cavity. Within each injection nozzle passageway is a heater probe which has an internal heater, preferably an electrical cartridge heater. The probe is secured by an integral seating flange to the mold housing to hold the probe coaxially aligned in the injection nozzle passageway and to hold the probe against shifting with thermal expansion and contraction of the manifold. The integral rear flange is positioned in front of manifold block and has a connecting passageway that communicates the manifold distribution channel with the injection nozzle passageway.
