Abstract: A plastic container having a base portion adapted for vacuum pressure absorption. The base portion including a contact ring upon which the container is supported, an upstanding wall and a central portion. The upstanding wall being adjacent to and generally circumscribing the contact ring. The central portion being defined in at least part by a central pushup and an inversion ring which generally circumscribes the central pushup. The central pushup and the inversion ring being moveable to accommodate vacuum forces generated within the container.

Abstract: A sidewall portion of a plastic container adapted for vacuum pressure absorption. The sidewall portion including generally rectangular shaped vacuum panels equidistantly spaced about the container The vacuum panels being defined in at least part by an upper portion, a central portion and a lower portion formed in a compound curve shape. The vacuum panels being moveable to accommodate vacuum forces generated within the container thereby decreasing the volume of the container.

Abstract: A software system for specifying design of at least two links in a packaging chain includes first and second software modules for specifying designs of first and second links in the packaging chain. The software modules have respective parameters each of which should not normally be breached. A conversion system interconnects the first software module and the second software module to enable data representing the link in the packaging chain specified by either the first software module or the second software module to be recognized in the other of the software modules. A feedback system provides feedback when there is a breach.

Abstract: A plastic container having a sidewall extending between a shoulder portion and a bottom portion. The sidewall has a substantially oval shape in cross-section and includes a pair of opposing columns and a pair of opposing panels. The columns are located at opposing ends of the oval shape and the panels are located at opposing sides of the oval shape. This configuration allows for reduced as-packaged vacuum pressures when the container is used in hot-fill applications.

Abstract: A packaging product for forming a package is disclosed. The package product comprises a planar member, with at least one surface (3) of the planar member having a first array of parallel creases (11) and a second array of parallel creases (13) perpendicular to the first array of creases, which creases define cutting lines and/or fold lines for forming the sides and the end flaps of the package.

Abstract: The tamper indicating closure disclosed herein is designed for use with containers having a threaded neck section and an annular bead or flange located below the threaded neck section. The tamper indicating closure includes a cap with a top wall and a downwardly extending annular side wall. The cap includes a thread on the inner surface of the side wall for locating the closure on the threaded section of the container neck, and a tamper indicating member is connected to the lower section of the side wall. The tamper indicating member includes an annular band with a plurality of upwardly extending locking tabs. A plurality of flexible hinges are used to interconnect the locking tabs and the annular band. The locking tabs are configured to react against the annular head or flange of the container neck to prevent the removal of the annular band from the container when the closure is in a closed position.

Abstract: A paperboard corrugating machine for forming board having two corrugated mediums joined at their flute tips without any intervening liner. The machine comprises a relatively heavy main frame (11) and a second frame (12) which is mounted for movement on the main frame. The main frame (11) carries two rolls (13 and 14) and the second frame (12) carries two rolls (15 and 16). Frame (12) can be locked into position and loaded against the upper roll (13), and the four rolls (13, 14, 15 and 16) lie in a single plane when the rolls are operational. With this construction, movement and twisting of the rolls (13 and 15) relative to each other, between which the fluted mediums are aligned flute tip to flute tip, is reduced.

Abstract: A hot fill container formed from a polymeric material is disclosed. The container comprises a base (4), a body (2), and a neck (1), wherein the body (2) comprises an odd number of spaced-apart panels (5) that are responsive to internal pressure changes in the container. Hot fill bottles of a given capacity having an uneven number of deformable panels, e.g., five of a given wall thickness, unexpectedly accommodate significantly higher volume reductions before collapsing and distorting in an uncontrolled manner than known hot fill bottles of the same capacity having an even number of panels, e.g., six of the same wall thickness.

Abstract: This invention relates to a method and apparatus for obtaining data relating to the compressive failure characteristics of a liner of a board sample which includes the following. A sample is aligned within a pivotal retaining mechanism of a testing device adapted to rotate about a line. A displacement force is applied at a constant rate to at least one edge of the liner such that the rotatable retaining mechanism allows self-positioning of the sample. Measurements are taken regularly of load and/or deflection observed until the liner fails.
