A preform for being blow-molded to than a container is provided herein. The preform comprises a finish portion that includes an opening to an interior of the preform and includes a tamper evidence ledge. The tamper evidence ledge cooperates with a tamper-evident ring portion of a cap to indicate that the cap has not been previously loosened after being installed by the manufacturer. A neck portion is disposed adjacent to the tamper evidence ledge. A tapered portion transitions from a diameter of the neck portion to a smaller diameter of a cylindrical portion. The cylindrical portion comprises an elongate member that culminates in an end cap. Threads disposed on the finish portion are configured to threadably receive the cap. A handling valley is disposed between the tamper evidence ledge and the threads. The handling valley enables gripping fingers to engage with and air-convey the container along a manufacturing assembly.

The present application includes an injection molding step and a stretch blow molding step. The stretch blow molding step is configured to include: a first step in which preliminary blow air is introduced into a preform to stretch the preform in a state in which a stretching rod does not contact the bottom of the preform; a second step which is executed after the first step, and in which the preliminary blow air is introduced into the preform and the stretching rod is moved at a set speed and pressed against the bottom of the preform to stretch the preform; and a third step which is executed after the second step, and in which final blow air is introduced into the preform to stretch the preform.

An apparatus for producing plastic bottles includes a molding machine to receive and mold the preforms into bottles; a labeling machine to label the bottles; a filler to fill the bottles; a packer to package the bottles; and a distributor arranged at an outfeed of the labeling machine or the filler to transfer the bottles to the packer. No buffers are positioned between at least one of the molding machine, the labeling machine, and the filler and at least one of the packer and the distributor to bloc-synchronize the at least one of the molding machine, the labeling machine, and the filler with the at least one of the packer and the distributer. The at least one of the molding machine, the labeling machine, and the filler being spaced a distance from the at least one of the packer and the distributor via one or more transfer starwheels.

A method for forming a container with an integral handle includes heating a preform having an integral handle in a first oven, stretching the preform, closing a first mold having a first mold recess and a second mold having a second mold recess around the preform, and blowing air into the preform. A handle pocket wedge block is inserted into a handle pocket of the integral handle of the preform within the first mold and the second mold.

Apparatus and method for producing plastic bottles. An apparatus for producing plastic bottles includes a blow molding machine to receive and to stretch blow mold preforms into bottles. The apparatus includes a modular machine to receive the bottles from the blow molding machine and to at least one of label or print on the bottles. The modular machine includes a first unit to perform a first task. The first unit is replaceable with a second unit. The second unit is to perform a second task different from the first task. The blow molding machine is bloc-synchronized with the modular machine to space the blow molding machine a distance from the modular machine.

A heating unit for heating preforms made of plastics material and having a flange separating a body and neck. The heating unit comprising a plurality of supports, each bearing a gripping member for gripping the preforms. The supports are movable in the heating unit such that each gripping member moves along a conveying path of the preforms. The heating unit also comprises a plurality of shells secured to the supports, where each shell is connected to one or more supports by an actuating member. The actuating member is mounted on said support to pivot about an axis situated at a distance from the conveying path of the preforms. The heating unit further comprising means for pivoting the actuating member to drive the shell from an open position to a protection position when the support to which said shell is connected is passing from an admission/releasing zone to a holding zone.

Apparatus and method for producing plastic bottles. An apparatus for producing plastic bottles includes a molding machine to manufacture preforms for plastic bottles. The apparatus also includes a blow molding machine to receive the preforms from the molding machine and to stretch blow mold the preforms into bottles. The apparatus also includes a labeling machine to receive the bottles from the blow molding machine and to label the bottles. The molding machine is bloc-synchronized with the blow molding machine to space the molding machine a first distance from the blow molding machine. The blow molding machine being bloc-synchronized with the labeling machine to space the blow molding machine a second distance from the labeling machine.

A gripper system includes a gripper module carrier and a gripper module for holding containers or container preforms, the gripper module having a gripper base and two gripper arms with gripping elements for at least partially gripping around a holding region of containers or container preforms, the gripper arms being mounted on the gripper base such that they can pivot relative to one another, the gripper module being releasably connected to the gripper module carrier, wherein the gripper system further includes a locking device for locking the gripper module to the gripper module carrier, and wherein the locking device is movable into a locking position for locking the gripper module to the gripper module carrier.

A method and an apparatus for producing plastic bottles, including a blow molding machine, a labeler, at least one further treatment machine, and transfer starwheels provided and arranged for the machine-to-machine transportation of the bottles in such a way that the bottles are transported without buffers between the at least three machines.

A preform 20 comprises a neck portion 22 having an opening 21, a cylindrical barrel portion 23, and a bottom portion 24 larger in diameter than the barrel portion 23, and has a corner portion 25 at a boundary between the barrel portion 23 and the bottom portion 24.
