METHOD OF HANDLING A PLASTIC CONTAINER HAVING A MOVEABLE BASE
A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.
BLOW MOLD UNIT AND BLOW MOLDING DEVICE USING SAME
In a fixing member 110 formed with an insertion hole 113 for inserting an elevation rod 111, a communication hole 114 communicating with the insertion hole 113 is formed to open at a side surface of the fixing member 110. A key member 112 is inserted into the communication hole 114 and engaged with a key groove 118 provided at the distal end of the elevation rod 111. By so doing, the elevation rod 111 and the fixing member 110 are coupled together.
Method for producing containers, comprising a delayed boxing operation
A method for producing a container (2) from a blank (3) in a mold (1) provided with a wall (4) and a mold bottom (8) that is movable relative to the wall (4) between a retracted position and a deployed position, the method including: a phase of introducing the blank (3) into the mold; a preblowing phase including the injection, into the blank (3), of a fluid pressurized to a so-called preblowing pressure, a blowing phase following the preblowing phase and including the injection, into the blank (3), of a fluid pressurized to a so-called blowing pressure greater than the preblowing pressure; a boxing phase including the displacement of the mold bottom (8) from the retracted position thereof to the deployed position thereof, initiated after the pressure in the blank (3) has reached the blowing pressure.
Systems and methods for handling plastic containers having a deep-set invertible base
A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.

The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.
Method of handling a plastic container having a moveable base
Method for processing hot-filled plastic containers are provided. In some embodiments, the method may include hot-filling a plastic container, sealing the container, and conveying the sealed container, each with an inner annular wall and a push-up portion in a first position. In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning the push-up portion from the first position to a second position under a mechanical force.
Apparatus for blow-molding plastic containers
An apparatus for blow-molding plastic containers includes at least one blow-molding station which defines at least one molding cavity which extends around a main axis of extension and further includes at least two lateral bodies and a respective bottom for each molding cavity that is defined by the blow-molding station. The bottom defines a recessed central portion, which is arranged around the main axis of extension, and a lateral containment portion, which has petal-shaped regions which have a substantially radial extension.
Electric heated base for container blow-molding device
A device for blow molding a container from a preform. The device includes a mold base and a pedestal for supporting the mold base. An electric heating element is beneath the mold base for heating the mold base. An insulator is between the heating element and the pedestal.
MOLDING SYSTEM, APPARATUS FOR TAKING OUT MOLDED PRODUCT, MOLD EQUIPMENT, AND METHOD FOR MANUFACTURING HOLLOW MOLDED PRODUCT
An apparatus for taking out molded product in a molding system has an insert portion, abutting portion, recess, and suction port. The insert portion is inserted in a hollow molded product via an opening portion serving as a blow pin extraction port of the hollow molded product. The abutting portion is arranged at the circumference of the insert portion and abuts on an outer circumferential surface of the hollow molded product spaced a predetermined distance from the opening portion serving as the blow pin extraction port. The recess is provided between the insert portion and the abutting portion, accommodates the opening portion in the state where the outer circumferential surface of the hollow molded product abuts on the abutting portion, and forms a stretch of closed space to the inside of the hollow molded product. The suction port is provided in the insert portion and sucks an ambient atmosphere.
METHOD OF PROCESSING A PLASTIC CONTAINER TO INCREASE INTERNAL PRESSURE
A method of processing a plastic container to increase internal pressure including blow-molding the container to comprise an invertible panel in the base and a standing ring, hot filling and sealing the container, feeding the container into an apparatus with a holding device and forcing a volume reduction and pressure increase into the container, and stacking the containers in bulk pallets on top of one another to increase top load and create a positive pressure within the distribution load of containers.
