  • Patent number: 7491358
    Abstract: A method and device serve the tempering preforms of a thermoplastic material. The preforms are modeled subsequent to tempering into a container inside a blow-molding mold by the action of a medium under pressure. During tempering, the preforms are heated by being acted upon by a heat radiation as well as cooled by being blown upon with cooling air, at least in the surface region. For compensation of a change in the surface temperature of the preforms due to operating ambient parameters, a change in the intensity in the subjecting of the preforms to cooling air is conducted. This takes place such that with simultaneous heating and cooling a basically constant surface temperature of the preform is attained. In addition, the intensity of heat radiation can be regulated for adaptation to at least one operating parameter.

  • Patent number: 7485252
    Abstract: Apparatus and method for making a molded plastic article having a stretched and crystallized neck finish. In one embodiment, a series of platforms are carried by a conveying apparatus for transporting a series of molded plastic articles along a predetermined path of travel through one or more treatment stations. At a finish widening station, the molded article, having a relatively wide and thin-walled blow-molded body portion, and a relatively narrow and thick-walled unexpanded neck finish portion, is positioned to enable insertion of a mandrel into an open top aperture of the finish portion to widen the finish. The mandrel may include a lower heated tapered portion for expanding the finish, and an upper cooled body portion on which the expanded finish may be cooled. The article may then be sent to a finish crystallizing station having a heating device that heats the widened finish portion for a time and temperature selected to crystallize at least a portion of the widened finish.

  • Patent number: 7476355
    Abstract: An injection blow molding apparatus has a rotatable turret with three laterally facing faces. The turret is rotatable between an injection position, a blow position and an ejection position that are angularly spaced from each other around an axis of rotation of the turret. A mold core holder is mounted on each face of the turret. Each core holder has a track, a wing pivotally mounted on each end of the track for movement between folded positions overlying the track at the injection position, and unfolded positions extending from the ends of the track at the blow and ejection positions. Mold cores are mounted on each track at a reduced spacing. The spacing can be increased by moving the wings to the extended positions and spreading out the mold cores on the track and the two wings.

  • Patent number: 7476354
    Abstract: A mold assembly includes a collapsible mount for releasably holding an insert within a mold cavity of the assembly in order to integrally form the insert with a molded article such as a tank liner. The collapsible mount includes a number of fingers secured to the mount and capable of being inserted through and expanded to engage the insert. The fingers are expanded after insertion through the insert by a core engageable with the fingers in order to securely hold the insert in position on the fingers of the mount and within the mold cavity. After formation of the article around the insert, the core can be disengaged from the fingers, which then move to a collapsed position such that the mount can be quickly withdrawn from within the insert and the mold cavity.

  • Patent number: 7459119
    Abstract: A multiplayer perform having at least a medium or intermediate gas barrier layer is prepared in advance by the injection molding of this perform in a predetermined shape that corresponds to the shape of a finished molded product. The body portion of this perform is heated to a blow moldable temperature. The heated perform is set in a primary blow mold (12), and is blow molded in the biaxial orientation to give a primary molded intermediate (5). The primary intermediate (5) is then heated to deform it forcibly by thermal shrinkage and thereby to give the secondary molded intermediate (6). The shrunken secondary intermediate (6) is set in a secondary blow mold (13), and is subjected to the secondary blow molding in the biaxial orientation to obtain a finished molded product, which is fixed thermally to give heat history to the PET resin.

  • Patent number: RE40941
    Abstract: The present invention includes processes and resulting structures for producing a modified polymer having interconnecting channels. The interconnecting channels act as controlled transmission passages through the polymer. A hydrophilic agent is blended into the polymer so that it is distributed within the polymer. In one embodiment, a releasing material is blended into the polymer so that the releasing material is distributed within the product. The product is solidified so that the hydrophilic agent forms passages in the product through which a desired composition is communicable to the releasing material that is entrained within the product. The solidified product may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.
