    Abstract: In that process for the production of hollow bodies from thermoplastic material by extrusion blow molding in which discontinuously extruded preforms are expanded in a blow molding mold, at least during that part of the filling phase which is typical of such a process, for an extrusion head, the distance covered by an ejection piston associated with a storage chamber and the speed at which the ejection piston is displaced within the storage chamber by the plasticised material are detected and compared by a central control and regulating device to the respective reference values. On the basis of the result of the comparison operation at least one operating parameter of the process, for example the delivery output of the extruder or the extent of the emptying strike movement of the ejection piston can then be adapted while still in the same working cycle in such a way that substantially the required preform volume is ejected.

    Abstract: An apparatus for the production of hollow bodies from thermoplastic material by blow molding using a blow molding mold which includes at least first and second mold portions to enclose a generally tubular extruded preform which is expanded within the mold under the effect of an increased internal pressure within the preform. To provide for asymmetric closing and/or opening movements of the mold portions relative to the preform, the blow molding mold is displaced as an entirety parallel to the direction of the opening and/or closing movements of the mold portions, more especially during the mold closing and/or opening procedure, so that an additional motion is superimposed on the movements of the mold portions.

    Abstract: A moulding apparatus having a two-part mould movable between a receiving station at which thermoplastics synthetic material is extruded into the mould and a release station at which a moulded hollow body is removed from the mould. This hollow body is then supported by a blowing and calibrating member before being gripped by a two-part gripper which moves the body from the release station to a transfer station in synchronism with the mould movement. The gripper parts are mounted on arms or levers supporting and/or guiding the mould parts.

    Abstract: A barrel of thermoplastic material has at least one connecting portion having an emptying opening and arranged in a trough-like depression in the upper end part of the barrel. In the region of the connecting portion the barrel has at least one inclined surface which extends between the upper end part of the barrel and the side wall of the barrel. The inclined surface is of such a configuration that in a barrel emptying position the emptying opening forms the lowest part of the interior of the barrel to permit at least almost complete emptying of the barrel.

    Abstract: A closure adapted to be applied to a neck of a vessel or container so as to seal a comparatively wide mouth in said neck has a rim or skirt which is divided up into a plurality of sections by slits between the sections depending from a lid portion of the closure and a stressing or tensioning band placed around the rim, the arrangement being such that there is at most only slight engagement between corresponding screw threads or the like on the neck and in the skirt when the closure is applied to the neck, full sealing engagement between the said screw threads being produced by tensioning of said band after the closure is in position on the neck, such tensioning causing the initially radially outwardly splayed said sections to be pulled radially inwardly on to the neck. The vessel and closure are preferably of thermoplastic material. Preferably tensioning of said band also causes the closure to move axially into more intimate contact with the vessel to compress a sealing ring and thereby improve the seal therebetween.
