Abstract: A pallet container includes a bottom pallet and a thin-walled inner container, made of thermoplastic material and resting on the bottom plate, for storing and transporting liquid or free-flowing goods. Closely surrounding the plastic container is a lattice tube frame which includes vertical and horizontal tubular rods welded to one another and which is securely fixed to the bottom plate. In order to improve the lattice tube frame durability while maintaining sufficient stacking load-bearing capacity, at least the vertical tubular rods have regions of low tubular profile height and high tubular profile height, wherein the regions of low tubular profile height are uniformly linear and positioned outside the intersections, and the regions of high tubular profile height are positioned in an area of the intersections.

Abstract: A blow-molding machine for producing blow-molded hollow bodies from a thermoplastic material, includes two blow-mold halves which can be horizontally displaced and provided with separate drive units for a transport drive and for the sequence of movements of the mold closing and locking device to open and close the blow mold halves. Conventional blow-molding machines are still equipped with hydraulic drives at least for the mold closing and locking device. In order to provide a blow-molding machine that can for example be operated under clean-room conditions, the drive unit of the blow-molding machine according to the invention is configured for the clamping elements of the mold closing and locking device as an electromotive direct drive with a spindle drive and a spindle mechanism with recirculating rollers.

Abstract: The invention relates to a pallet container with a thin-walled inner receptacle preferably made from thermoplastic material for the storage and transport of liquid or free-flowing goods, wherein the plastic container is closely surrounded by an outer cage jacket of crossed hollow bars which are configured with dimples by means of which bending points in the cage jacket are established so that when the pallet container is subjected to drops from certain heights, the cage jacket incurs a plastic deformation, thereby preventing fracturing or tearing of the hollow bars from the cage jacket.

Abstract: The invention relates to a method and a device for producing blow-molded plastic hollow bodies (60). The device is of enhanced design which avoids the shortcomings of traditional blow-molding technology. The extrusion die according to this invention is adjustable for different settings to produce different, partly overlapping wall thicknesses of the parison blank in order to compensate for the insufficiencies inherent in blow-molding and to obtain a finished blow-molded product with as consistent and uniform a wall thickness as possible, with an overlay, for instance in vertical wall areas, of evenly spaced longitudinal ribs (68). A technical concept is introduced whereby, as a novel process, the two conventional measures used to achieve a uniform wall thickness in the finished blow-molded hollow body are complemented by an additional, third step which makes it possible to produce containers whose hollow bodies (60) are provided with targeted, intentional and reproducible irregular wall thickness patterns.

Abstract: A pouring spout for liquid containers to allow for a dosed and continuous ventilation of the container interior and thus a regular pouring of the liquid independent of the degree of tilt of the container, includes a ring-shaped upper part and a tubular segment attached to the ring-shaped upper part and having at least one ventilation opening through which the air enters in a dosed manner. Provided in the lower part of the tubular segment is a partition which extends on an inner side of the tubular segment in substantial parallel relationship to the tubular segment and is connected laterally with the tubular segment. The partition wall has an upper part distal bottom wall for connection to the tubular segment to form a so-called air trap.

Abstract: The invention relates to an extrusion head for producing a tubular parison (22) in order to manufacture large-volume, blow molded plastic hollow bodies. The inventive extrusion head has an adjustable ring-shaped tube outlet nozzle for selectively adjusting the nozzle opening (20) in order to alter the wall thickness of the exiting parison (22). In order to provide a multiple adjustability of the extruded tube cross section, the invention provides that the extrusion head comprises at least three separate nozzle/mandrel gap adjustment elements (D 0=mandrel, DS I, DS II, DS III) which are differently profiled and exchangeable. The elements can be individually and/or simultaneously brought into working contact with the exiting parison (22) in the mandrel gap (20) from inside and/or outside, whereby at least two of the adjustment elements (D 0=mandrel, DS I, DS II, DS III) are configured such that they can be adjusted.

Abstract: A lidded plastic barrel (10) consisting of a barrel body (12), a barrel lid (14) and a clamping ring or ferrule (16). The U-channeled rim (20) of the barrel lid (14) includes an additional, rotationally symmetrical sealing web (36) and a gasket (22) is positioned between the outer circular side wall (26) of the lid and the said sealing web (36). Between the sealing web (36) and the inner circular side wall (28) of the lid an annular recess (38) opens up toward the bottom while the sealing web (36) and the inner circular side wall (28) are spaced apart and are mutually connected by way of an upper flange (40).

Abstract: The invention refers to a pallet container (10) including a bottom pallet (12), a plastic receptacle (14) arranged thereon and a support jacket (16) closely surrounding the plastic receptacle (14) and fixedly connected (but detachably) on the bottom side with the bottom pallet (12). Conventionally, the thickened pinch-off seam produced in the lower receptacle plate (and also in the upper receptacle plate (22)) through pinching off the tubular parison interferes with a flow of the residual liquid to the bottom-side discharge valve (28). Thus, in accordance with the invention, the inner plastic receptacle (14) is provided with welded pinch-off seams (30) on two diametrically opposing side walls, preferably with one seam ending directly in the integral discharge valve (28). The discharge valve (28) thus lies in the middle of the side walls with the joining weld for the first time entirely in the tube pinch-off area around the blow mandrel within the tube.

Abstract: A reusable container, made of a thermoplastic material, with at least one filler and drain opening (18) in the top panel (20) and with a circumferential upper and lower stacking ring (12, 16). To permit reuse, direct stackability, good residual drainability as well as good manipulability of the container, this invention provides for the upper stacking ring (12) to have a slightly larger diameter than the lower stacking ring (16) and to feature on the inside of its upper rim a recess matching the diameter of the lower stacking ring (16) and on the outside a vertically protruding circular flange, so that, when stacked one container atop the other, the lower stacking ring of the upper container fits into the recess in the upper stacking ring of the barrel underneath and is snugly centered therein by the vertically protruding circular flange. This allows for the direct, multiple, secure stacking of the containers that are the object of this invention.
