  • Patent number: 8945459
    Abstract: A plastic film preform is expanded to form a container. The preform has a longitudinal axis that extends from an open top to a closed bottom. The preform is pressurized with a first pressure sufficient to cause side walls of the preform to expand outwardly and the bottom of the preform to be drawn inwardly thereby reducing a length of the preform along the longitudinal axis. Side molds are closed around the side walls of the preform, the closed side molds being larger than the expanded side walls. A bottom mold is closed to be adjacent to the bottom of the preform after pressurizing the preform with the first pressure. The preform is pressurized with a second pressure sufficient to expand the preform to fill the closed molds. The preform is thereby significantly stretched in a direction perpendicular to the longitudinal axis and minimally stretched along the longitudinal axis.

  • Publication number: 20130219831
    Abstract: A container can have a body with an integrally formed base attached to the body. The base includes a concave annular wall extending from the container sidewall to a standing surface, and an inner wall extending from the standing surface to a substantially flat inner annular wall. The inner annular wall is recessed in the base and is substantially perpendicular to the container sidewall. The inner annular wall includes a centrally located dimple. The dimple includes a plurality of spaced apart and radially extending indented ribs. One or more of the ribs extend radially into a brace that tapers to meet the inner annular wall.

  • Patent number: 8460599
    Abstract: A method and an apparatus for the economical production of containers from thermoplastic material with a blow moulding machine (3) are disclosed. For shaping the containers at least one first pressure channel (21) is provided, supplying a first pressure. Likewise at least one second pressure channel (22) is provided, supplying a second pressure, wherein the first pressure is lower than the second pressure. The air in the first pressure compartment (21) is used for the pre-blowing or for other blowing steps of the containers. The air in the second pressure compartment (22) is used for the final blowing of the containers. The final blown containers are vented into the first pressure compartment (21). A control unit is provided which maintains an essentially constant pressure in the first pressure compartment during the pre-blowing and the venting into the first pressure compartment. A pressure level of the external pressure reservoir (20) can be adjusted accordingly.

  • Patent number: 8409490
    Abstract: The technical problem to be solved by this invention is to develop a polyester resin container that can be retort-processed at a temperature in the range of above 120° C. to about 130° C. The object of this invention is to provide a polyester resin container, which is capable of improving the productivity and quality of retort foods, and a molding process thereof. The process of this invention is a double blow molding process, which comprises a primary blow molding step in which a preform is biaxially drawn and blow molded into a primary intermediate product, a thermally shrink-molding step in which the primary intermediate product is heated and forcibly shrink-molded into a secondary intermediate product, and a secondary blow molding step for blow molding the secondary intermediate product into a container, wherein the process is characterized in that a mold temperature higher than 210° C. is used in the secondary blow molding step.

  • Publication number: 20120299224
    Abstract: A method of forming a plastic container from a preform. The method comprises injecting a forming liquid into the preform at a predetermined system pressure range, a predetermined flow rate, and a predetermined duration sufficient to create a pressure spike at a peak pressure. The peak pressure being greater than the system pressure to urge the preform into the mold cavity, thus creating enhanced container definition, reduced post mold shrinkage, lower residual material stresses, and/or an improved transfer of the mold geometry and engraving to the final formed container.
