The concave rib in side cross-section includes a radiused transition surface extending from the base portion to an angled inner surface, the radiused transition surface has a radius of curvature r.sub.1 of at least 0.10 inches and the angled inner surface has an angle a relative to the reference plane of between 28 degrees and 80 degrees. A method and mold assembly for making the container is also provided.

A plastic container having a mouth as well as a main body on an outer surface of the plastic container and/or through the outer surface of the plastic container itself using a wall material and in the form of a raised wall portion or a wall depression in the form of a wall structure. Container information is attached, wherein the container information on the finished plastic container replaces a label. The finished produced plastic container is free of a label, and at least one stiffening region is formed on an outer surface of the plastic container and/or is formed by a wall material of the container itself, in particular the stiffening region defines at least two regions on the outer surface which are separated from each other by the at least one stiffening region and the wall structures are distributed on at least these two regions.

Disclosed is molding unit for the forming of containers made of thermoplastic material including: two half-molds delimited by a front joint face and by a rear assembly face, with the two half-molds being able to occupy a joined position via their joint face; and a molding cavity that is made of two parts in each joint face, where the cavity opens vertically upward via a passage opening. In the joined position, the assembly faces of the mold have two planes of symmetry that intersect at a central vertical axis of the mold. The central axis of the passage opening is offset transversely in relation to the central axis of the mold.

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 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 method for transferring a negative structure of a surface of an inner wall (51) of a blow molding tool (1) onto a surface of a plastic container. The method comprises the steps of heating at least one region (511) of a mold cavity (6) of a molding body (4) of the blow molding tool (1), on which the negative structure is formed, inserting a preform into the mold cavity (6), closing the blow molding tool (1), molding the plastic container by inflating the preform and bringing the preform to lie against the inner wall (51) of the mold cavity (6), cooling the region (511) by supplying a coolant through temperature control channels (54), and removing the plastic container from the mold.

The invention relates to a blow molding tool for a blow molding machine for producing plastic containers in an extrusion or stretch blow-molding process. The blow molding tool comprises two blow mold halves, each of which comprises at least one molding body in which at least one mold cavity is disposed, and a baseplate that receives said molding body. An insulation block consisting of a thermally insulating material is arranged between the molding body and the baseplate and, optionally, further components of the blow mold halves.

An injection head for the fabrication of a container from a preform. The injection head interfaces with a preform to establish fluid communication between a liquid supply and the preform. An injection valve is disposed within the injection head and is configured to selectively permit fluid communication through the injection head. A liquid supply control mechanism and a control mechanism of the injection valve's opening allow fluid communication through the injection head. The control mechanism of the injection valve's opening is activated by the liquid under pressure in the injection head cavity when the liquid supply is opened.

A blow mold for making PET containers comprising an inner surface corresponding to the outer outline of the container, on which there are one or more cavities or projections configured to make corresponding respective projections or cavities of the outer surface of the container, wherein the mold comprises one or more venting grooves along the edge delimiting said cavities or projections. A plurality of venting holes are possibly arranged along such grooves, as well as it is also possible for some venting holes to be arranged outside thereof. The width and depth of these are selected according to the wall thickness of the container to be blown to prevent that the deformation of the container during the blowing obstructs the venting grooves and leaves visible marks on the container.

An injection head for the fabrication of a container from a preform. An injection head interfaces with a mouth of the preform to establish fluid communication between a liquid supply and the mouth. The injection head includes an injection valve disposed within an outer shell of the injection head and configured to selectively permit fluid communication through the injection head upon displacement between an opened and a closed position. The injection head also includes an injection head cavity disposed between the injection valve and the outer shell and connected to the liquid supply. A liquid supply control mechanism and a control mechanism of the injection valve's opening allow fluid communication through the injection head. The control mechanism of the injection valve's opening is activated by the liquid under pressure in the injection head cavity when liquid supply is opened.
