  • Patent number: 8177098
    Abstract: A one-piece plastic container includes a body defining a longitudinal axis and having an upper portion, a sidewall portion and a base portion. The upper portion has a spout defining an opening into the container and a finish offset radially outwardly from the spout. A trough defines a passage into the body. The trough slopes toward the passage and defines a non-orthogonal angle relative to the longitudinal axis. According to other features, the sidewall portion is integrally formed with and extends from the upper portion to the base portion. The base portion closes off an end of the container. The finish defines at least one thread, for attaching a closure thereon.

  • Patent number: 8113370
    Abstract: A container structure for a hot fill liquid may employ an upper portion defining a mouth, a shoulder portion integrally formed with and extending downward from the upper portion, a bottom portion defining a base, and a body and sidewall extending between and joining the shoulder and bottom portions. The sidewall may employ a pair of opposing columns oriented diagonally relative to the base and concave inward relative to a container central vertical axis before the container is filled. The columns become concave inward to a lesser extent when the bottle is under an interior vacuum. The sidewall may also employ a pair of opposing, compound angle vacuum panels oriented diagonally relative to the base. A vacuum initiator groove is formed in each of the vacuum panels to initiate panel movement during liquid content cooling. The vacuum initiator groove is generally coincident with a vacuum panel longitudinal centerline.

  • Patent number: 8113369
    Abstract: A blow molded container has a neck portion defining a mouth. The neck portion leads into a shoulder portion and a bottom portion forms a container base. A sidewall portion connects the shoulder portion and the bottom portion and employs a first pair of opposing convex vacuum panels and a second pair of opposing convex vacuum panels. The first pair of opposing convex vacuum panels is larger in surface area than the second pair of opposing convex vacuum panels. A vertical column at each corner of the container joins the first pair of opposing vacuum panels to the second pair of opposing vacuum panels. A structural convex arch resides above and below each convex vacuum panel. Each of the vertical columns are molded into the structural convex arches. Vacuum initiator grooves may be molded into the first and second pair of opposing vacuum panels to control vacuum panel movement.

  • Publication number: 20110300249
    Abstract: An apparatus for simultaneously forming and filling a plastic container is provided. A mold cavity defines an internal surface and is adapted to accept a preform. A pressure source includes an inlet and a piston-like device. The piston-like device is moveable in a first direction wherein liquid is drawn into the pressure source through the inlet and in a second direction wherein the liquid is urged toward the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and creating a resultant container. The liquid remains within the container as an end product.

  • Publication number: 20110220668
    Abstract: A heat set container having a shoulder portion and a sidewall portion extending from the shoulder portion to a base. The base closes off an end of the container. The shoulder portion, the sidewall portion, and the base cooperate to define a receptacle chamber within the container into which product can be filled. The sidewall portion defines a major container diameter of the container. The sidewall portion includes an upper vacuum absorbing region joined to a lower vacuum absorbing region at a reduced waist section. The reduced waist section forms a minor container diameter which is less than the major container diameter. In some embodiments, such configuration forms an hourglass, heat-set container, wherein the upper vacuum absorbing region and the lower vacuum absorbing region are collectively shaped to provide flexible absorption of an internal vacuum within the receptacle chamber.

  • Publication number: 20110217494
    Abstract: A blow-molded plastic container comprising a base portion having a flexible standing ring radially extending therefrom. The flexible standing ring is disposed about a lowest most portion of the container and operable to support the container on a surface. The flexible standing ring defines an annular groove thereabout that collapses in response to internal vacuum forces and/or external loading forces. The container further comprises a body portion that extends from an upper portion to the base, such that the upper portion, the body portion and the base cooperate to define a receptacle chamber within the container into which product can be filled.

  • Patent number: 7918355
    Abstract: A blow-molded plastic container includes an upper portion having a finish, a body portion and a base. At least one groove is formed in a radial sidewall of the finish. The groove slopes gradually downward along the radial sidewall and away from an opening into the container. A method of making the blow-molded plastic container includes disposing a preform into a mold cavity having a surface defining a body forming region, a finish forming region and a moil forming region. The preform is blown against the mold surface to form an intermediate container having a body portion, a finish and a moil portion. The moil is severed from the finish to define the opening into the container. A closure member is adapted to selectively mate with the finish on the container. At least one thread is formed on the closure member.
