A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.

A container production method by liquid blow molding. The method includes a head space forming step of forming a head space in the upper portion of a container, in which, with the container disposed in a cavity, a bottom panel portion molded into an upward convex shape on a bottom of the container is inverted by pushing it down with a pushing rod and is plastically deformed into a downward convex shape.

A method for forming a container with an integral handle includes heating a preform having an integral handle in a first oven, stretching the preform, closing a first mold having a first mold recess and a second mold having a second mold recess around the preform, and blowing air into the preform. A handle pocket wedge block is inserted into a handle pocket of the integral handle of the preform within the first mold and the second mold.

A mold for manufacturing, by extrusion blow-molding, containing two parts having at least a first section having a first molding surface having a plurality of contact regions configured to simultaneously form, by pressing, regions for fixing at least one internal component to the inside of a parison, and a second section having a second molding surface. The second section of the part of the mold is movable with respect to the at least one first section associated with the part of the mold.

A fuel tank has a built-in component with a head portion, a neck portion, and a shoulder portion, and has the built-in component anchored to a tank body with a parison wrapped around the neck portion during molding. The fuel tank includes a deformation prevention structure configured to prevent a wrapping parison portion wrapped around the neck portion from being deformed due to pressure acting on the tank body. The deformation prevention structure is configured to include one of a stepped portion provided in the shoulder portion, a convex portion, and a recess.

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.

A stretch-blown plastic container, includes a container body which encloses a filling volume with a container bottom; a container neck which adjoins an opposite end of the container body, having a container opening and an integrated handle region, the handle region being hollow and joined to the filling volume which is enclosed by the container body; and between the handle region and the container body, a through opening recessed and bordered over its entire periphery by wall parts of the container body and of the handle region which have been welded to one another.

Provided is a method for producing a double-layered container which can be easily produced using molding equipment that is not much different from conventionally used equipment and which comprises: a rigid outer layer container part; and a flexible inner layer container part of which the capacity can be changed inside the rigid outer layer container part, wherein, when a pair of partial molds are brought close to each other in order to be combined to form a split mold, at least parts of the joining faces of the pair of partial molds pinch a small outer diameter portion of a parison so as to form a gap burr, and, when a cap is screwed on, a gap for introducing external air in the interlayer of the double-layered container is formed at the small outer diameter portion from which the gap burr has been removed.

The invention relates to a plastics connecting seam for the fluid-tight connection of at least two plastics surfaces. The plastics connecting seam is in the form of a plastics connecting seam that supports strength under a load in such a way that a load acting in a standard load direction increases the connection strength of the seam.

A container consisting of plastic material that is produced using the blow, fill and seal method and the filler material of which, enclosed by a container wall (15, 20), can be autoclaved, is characterized in that at least one shaping means (19, 21, 23, 25, 29, 33) is provided in the container wall (15, 20), which ensures, despite a low relative air volume in the container, that when administering the filler material by infusion the container wall (15, 20) collapses at least partially reducing the volume, without aeration of the container.
