The invention relates to a container (1) for receiving a liquid content, comprising a container wall (10) which surrounds a container interior (12) and comprises an opening (8). The container wall has an opening region (2) at the opening, a base region (4) arranged opposite the opening region, and a lateral region (3) which extends between the opening region and the base region, and the container wall has a dimensionally stable central region (22) in the base region and a flexible flat region (24) which encircles the central region. The container wall transitions from the central region into the flat region at an angle such that an edge (26) which encircles the central region is formed in the container wall between the central region and the flat region. The invention further relates to a blow mold (31) for producing such a container.

An air root pruning container for growing a plant includes a base and a sidewall upwardly extending from the base. The sidewall includes stepped sidewall sections, each stepped sidewall section including a plurality of generally vertical sidewall panels having successively larger cross-sectional dimensions with distance from the base and horizontal ledges extending between an upper edge of an adjacent lower one of the sidewall panels and a lower edge of an adjacent upper one of the sidewall panels. The sidewall further includes a plurality of ribs, each rib formed between two of the stepped sidewall sections and extending inwardly across the ledges of the two stepped sidewall sections, wherein each rib has two legs that extend apart to form an outwardly-directed open channel. Still further, the sidewall includes holes formed in the sidewall, each hole formed directly between a ledge and a leg of one of the ribs.

Mold bottom for the manufacture by blow molding of a container that has a bottom that is equipped with a seat, with this mold bottom including a unit that has a molding face bearing the at least partial impression of the bottom of the container, with a pressure-release air vent being formed in the unit and emptying out, via an inner opening, on the molding face and, via an outer opening, into a pipe for exposure to air, with this mold bottom also including an insert that is provided with at least one projection housed in the air vent and that has a terminal face bearing the impression of at least one part of the seat of the container, with this insert being provided with an inner circuit for heat regulation of the projection and being mounted to move in relation to the unit.

A mold system for forming a container having a longitudinal axis and a transverse direction that extends transverse to the longitudinal axis. The mold system includes a sidewall system for molding the sidewall portion of the container. The mold system also includes a base system for molding the base portion of the container. The base system is operable for forming the entire base portion of the container including a central pushup portion, a contact surface for supporting the container, and at least one strap extending along the base portion in the transverse direction. The strap defines a strap surface that is spaced offset in a direction parallel to the longitudinal axis from the contact surface. The strap surface extends in the transverse direction to be adjacent the sidewall portion such that the at least one strap surface is visible from a side of the container.

A blow molding tool (1) for a blow molding machine (1). The blow molding tool (1) comprises at least one first blow mold half (2) and one second blow mold half (3). The first blow mold half (2) has a baseplate (4) and a molding body (5). At least one mold cavity (6) with an inner wall (51) is arranged in the molding body (5). At least one region (511) of the inner wall (51) of the mold cavity (6) comprises, in the associated section of the molding body (5), separate temperature control channels (54) for controlling the temperature of the region (54).

A mold half, especially for blow molding of thermoplastic articles, has a mold body defined at least in part by a single piece of aluminum or aluminum alloy mold material having a cavity and a pinch-off or other feature area and further having a metal-matrix composite (MMC) layer formed integrally in the mold body at the pinch-off or other feature area. A mold is fabricated from two mated mold halves. A process of producing a mold half involves machining a single piece of mold material to provide a mold body having a cavity and a pinch-off or other feature area, the pinch-off or other feature area being of smaller dimension than required for the mold half, integrally forming a metal-matrix composite layer in the pinch-off or other feature area to build up the pinch-off or other feature area to at least a dimension required for the mold half. The metal-matrix composite comprises an aluminum-nickel alloy matrix (e.g. AI-12Si alloy alloyed with Ni) having WC particles embedded therein or a aluminum matrix (e.g. AI-12Si alloy) having TiC particles embedded therein and has greater wear resistance, greater strength, greater toughness or any combination thereof than the mold material.

A bottle having good mechanical properties and lightness due to its bottom design includes a bottom, a body, and a neck. The bottom has a dome, a coronal arch, an annular seat, a side wall, six main radial grooves, five secondary radial grooves situated between the main grooves, each having an end Ev in the arch, and a peripheral end Ep in the side wall. The bottom is such that the ratio Mf/Vuf, wherein Mf is the weight of the bottom and Vuf is the useful volume of the bottom, is less than or equal to 0.050 g/mL and the ratio ?.sup.do/H.sup.do, wherein ?.sup.do is the diameter of the dome at its base and H.sup.do is its apex height along an axis Z, is greater than or equal to 4.4. The invention also relates to a manufacturing method and a mold for the bottle.

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 blow molding device in which a preform is injection-molded, the injection-molded preform is temperature-controlled by a temperature adjusting unit, and the temperature-adjusted preform is blow-molded, wherein the temperature adjusting unit has a multistage structure in which an uppermost stage has the highest temperature structure, and the mold surface temperatures of lower stages and other than the uppermost stage are set to be 10? C. or more lower than the glass transition temperature of the preform.

The present disclosure includes a thread insert for a blow mold assembly configured to form a polymeric container. The thread insert includes: an inner mold surface defining threads, the inner mold surface configured to form a finish of the container; a first bore defined by the thread insert; and a first heating element seated within the first bore and configured to heat the inner mold surface.
