APPARATUS FOR FORMING PLASTIC PREFORMS INTO PLASTIC CONTAINERS WITH A COVER DEVICE ARRANGED ON THE STRETCHING DEVICE
An apparatus for forming plastic preforms into plastic containers, includes a transport device, which has a rotatable transport carrier on which a plurality of forming stations is arranged. The forming stations each have application devices for applying fluid medium to the plastic preforms. The forming stations each have stretching devices for stretching the plastic preforms in the longitudinal direction thereof. The stretching devices each have at least one stretching rod which can be moved in the longitudinal direction of the plastic preforms. The apparatus has a clean room, within which the plastic preforms are expanded into the plastic containers, and a sealing device in order to seal the clean room from a non-sterile environment. The sealing device has at least one circumferential channel which can be filled with a liquid, characterized in that the clean room is closed with a cover device, and this cover device is fastened at least to at least one stretching device by fastening devices.

Apparatus for producing plastic bottles
An apparatus for producing plastic bottles comprising: a blow moulding machine including a blow moulding carousel being configured to transform a succession of plastic preforms into respective bottles; a filling machine including: a filling carousel, and a plurality of handling units; a labeling unit configured to feed a succession of labels to be attached to the respective bottles; and a conveying system configured to transfer the bottles within the apparatus. The labeling unit is arranged peripherally to the filling carousel and is configured to feed the labels to the handling units carrying the respective bottles while the handling units are advanced by the filling carousel. The conveying system includes a plurality of consecutive transport star wheels transferring the bottles in a continuous stream from the blow moulding carousel to the filling carousel.
NOZZLE FOR BLOW-MOLDING STEPPED FINISH PREFORM
An apparatus for a nozzle is provided for engaging with lightweight preforms for blow-molding the preforms into plastic containers without damaging the finish portion of the preforms. The nozzle comprises a first cylindrical portion including a first seal, a second cylindrical portion including a second seal, and a tapered portion between the first and second cylindrical portions. The first and second cylindrical portions include diameters that are less than respective diameters of interior surfaces within the finish portion. The first and second seals are disposed around respective circumferences of the first and second cylindrical portions and configured to tightly engage with the interior surfaces of the preform while maintaining clearance between the nozzle and the interior of the finish portion. In some embodiments, the seals are configured to stabilize an orientation of the preform after being pressed onto the nozzle and facilitate conveying the preform along a manufacturing line.
CONTINUOUS BLOW MOULDING MACHINE, PREFORMS, SYSTEM AND PROCESS
A continuously rotating, non-symmetric preform feed, stretch-blow-moulding machine dedicated to the stretch-blow-moulding of containers from non-symmetric injection moulded preforms; the non-symmetric preforms including an integral handle extending from a first junction point to a second junction point on a body of the preform; the body of the preform and the integral handle constituted from the same material.
Forming mold and injection mold
A forming mold is used when forming a preform, which has a neck portion and a barrel portion, and whose barrel portion is filled with a molding material over the entire axial direction thereof, by injection molding; forming a space part in the barrel portion of the preform to convert the preform into an intermediate molded product; and blow-molding the intermediate molded product to form a hollow container which is a final molded product. The forming mold is equipped with a boring rod which is inserted from the neck portion side into the barrel portion of the preform to form the space part of at least a predetermined depth in the barrel portion.

Method of delivering a liquid volume and associated apparatus
An apparatus and method of delivering a predetermined volume of a liquid product, defined as the liquid end product, formed by addition of a first and second liquid product, into a thermoplastic container formed from a heated preform positioned in a mold and having an opening opposite an injection head. Prior to injecting the second liquid product into the preform causing expansion of the container, the preform is at least partially, filled with the first liquid product.

Liquid blow molding apparatus and preform
A construction that prevents liquid from dripping from a nozzle and adhering to a product when the nozzle is separated from a mouth of the product after liquid-blow molding. A preform includes a mouth, a body, and a neck support portion, and is provided with a step surface on an inner peripheral face adjacent to the neck support part. A liquid blow molding apparatus includes a nozzle that is inserted in the mouth of the preform, a pressurized liquid-supply unit that supplies pressurized liquid to the nozzle, and a sealing member that is formed in a cylinder and fits on an outer peripheral face of the nozzle abuts the step surface, in an axial direction, when the nozzle is inserted in the mouth of the preform to seal the gap between the nozzle and the inner peripheral face of the preform.
