In one example, a structure is provided that includes a plastic body having a unitary, single-piece construction. The plastic body further includes a substantially hollow interior, and a parting line that extends around a portion of the perimeter of the structure. The structure also includes a solid compression molded element that is integral with the plastic body. The solid compression molded element is configured and arranged such that the parting line is not connected to the solid compression molded element.

A multiple-chamber container that is extrusion blow molded with a single neck finish and a method to trim the single neck finish is provided. The physical appearance of the multiple-chamber container before the trimming process differs from the multiple-chamber container after the trimming process. The multiple-chamber container includes multiple openings that are configured to engage with a single cap after the trimming process to create a seal. The multiple-chamber container may contain different materials, such as liquids, gel-like substances, granular materials, food, etc. that are not permitted to flow from one chamber to the other chamber when the cap is engaged with the chamber openings.

A double walled container has a container bottom that is blow molded after an intermediate portion of a parison in the vertical direction is sandwiched by a split mold from the horizontal direction; at least a portion of the container bottom is sandwiched by the split mold; the container bottom has a bottom projection on the underside of the container bottom made of the outer layer of a rigid outer layer container and the outer layer of a flexible inner layer container; in the bottom projection, an extended portion of the rigid outer layer container and an extended portion of the flexible inner layer container have protrusions and recesses of different heights in the horizontal direction; and the protrusions and recesses are combined so that the extended portions of the rigid outer layer container and the flexible inner layer container do not shift vertically with respect to each other.

Method for processing hot-filled plastic containers are provided. In some embodiments, the method may include hot-filling a plastic container, sealing the container, and conveying the sealed container, each with an inner annular wall and a push-up portion in a first position. In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning the push-up portion from the first position to a second position under a mechanical force.

A tank that includes a tank wall composed of a plastic material, and at least one reinforcing profile member configured to minimize deformation of the plastic tank. The at least one reinforcing profile member is configured for arrangement on an outer side of the tank wall to be engaged by the tank wall and establish a positive material bond connection therewith. The at least one reinforcing profile member has a retaining geometry region with a plurality of openings through and/or into which material of the tank wall extends and onto a rear side of the reinforcing profile member facing away from the tank wall to thereby establish the positive material bond connection between the tank wall and the at least one reinforcing profile member at the retaining geometry region.

A tool case with single and double wall sections, the double wall sections extend from one edge or from a corner of part of the case and are defined by a cut line, the cut line changes in height as the double wall sections have contours to conform to the tool to be held. The double wall sections may include supporting portions which are sections where the inner surfaces of the two walls are fused or welded together to create a support which transfers load from the tool between the two walls of the double wall section. In certain aspects, the cut line defines a large internal area of single wall as compared to the overall perimeter of the case or case half.

A liquid-containing container manufacturing method includes: a liquid blow molding step of, in a state in which a reversal panel formation part forms a convex surface projecting toward inside of a cavity, supplying a pressurized liquid into a preform placed inside a cavity, to mold the preform into a container including a reversal panel; and a headspace formation step of pressing the container by a press part to reverse the reversal panel, and thereafter releasing press by the press part to increase a volume of the container and thereby form a headspace.

A method for producing a container from a blank, inside a forming unit having a mold and a movable insert controlled by a variable-flow solenoid valve, a control unit linked to the solenoid valve. The method comprises developing a boxing curve characterizing the successive positions of the insert; determining, based on a reference blowing curve, points of inflection; measuring, on the boxing curve, distances actually travelled by the insert between points in time, some of which correspond to these points of inflection; and comparing the values of the measured distances with nominal values. If there is a difference between a measured value and a nominal value, controlling, by the control unit, a modification in the flow rate setpoint of the solenoid valve for the next production cycle.

In one example, a structure is provided that includes a plastic body having a unitary, single-piece construction. The plastic body further includes a substantially hollow interior, and a parting line that extends around a portion of the perimeter of the structure. The structure also includes a solid compression molded element that is integral with the plastic body. The solid compression molded element is configured and arranged such that the parting line is not connected to the solid compression molded element.

A method for producing a shoe sole. To be able to produce the shoe sole in an economical fashion and with easily selectable spring and damping characteristics, the invention has the following steps: a) extruding a plastic hose and feeding the plastic hose into a blow mold; b) blow molding the plastic hose into a sole hollow body, wherein recesses are introduced on mutually opposing walls of the sole hollow body during the blow molding process, such that parts of the walls are brought into contact with one another and form a supporting structure between the mutually opposing walls; c) removing the blow-molded sole hollow body from the blow mold; d) at least partially filling the blow-molded sole hollow body with plastic bodies, wherein the plastic bodies are added through a first opening in the sole hollow body.
