  • Publication number: 20010015331
    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.

  • Patent number: 6116453
    Abstract: This invention relates to a cylindrical, blow-molded lidded barrel (wide-mouthed drum) with a barrel lid and tension-ring closure. Previously known lidded barrels have comparatively little ability to withstand falls and are therefore not well-suited for handling liquids. Owing to the special configuration of the barrel lid and the barrel mouth edges as well as by a special matching of the individual components to one another, the lidded barrel according to the invention can be manipulated in the filled state with the same barrel-gripping tool (parrot's beak), ans is universally employed and in industrial use for modem plastic L-ring bung barrels or normal steel bung barrels. By improving the strength of the lidded barrel when it is dropped, the barrel is also made especially well-suited for handling liquids since it remains liquidtight even when dumped or dropped from great heights.

  • Patent number: 5975881
    Abstract: A blow molding machine, includes a base frame, a blow mold adapted for receiving a tubular parison and having a first mold support plate for support one mold half and a second mold support plate for support of another mold half. A transport unit is mounted to the base frame for so moving the first and second support plates that the mold halves are free from any direct, form-fitting coupling, with the transport unit including a first drive mechanism operatively connected to the first support plate and a second drive mechanism operatively connected to the second support plate and operating independent of the first drive mechanism. Secured to the support plates is a locking mechanism for pinching off the tubular parison and clamping the mold halves during the blow molding operation.

  • Patent number: 5941406
    Abstract: The object of this invention is a lidded barrel with a barrel lid and a clamping-ring closure. Between its flat lid plate and its outer rim, the barrel lid is provided with a circular, perimetric groove while also featuring in its periphery at least one bung well with or without a bunghole. When a barrel is dropped, the areas around the bung well are most vulnerable to breakage, i.e. it is in these areas that the barrel lid is most likely to slip out of the clamping ring with leaks resulting. In order to improve leak resistance of a lidded barrel, especially one suitable and approved for hazardous liquids, under extreme stress-load conditions, the area around the bung wells of the barrel lid is to be stress-relieved in the event of overstress (dropped barrel).

  • Patent number: 5607075
    Abstract: The invention relates to a conical lidded drum made of thermoplastic.To avoid step-like changes in diameter or hollow borders as a stacking rim on the outer drum body, according to the invention, a second upset surface flange (12) is formed out in the region of the upper third of the drum (34) on the outer wall of the drum body (10). Advantageously, the conical drum wall (14) extends linearly in a straight line from the upper first surface flange (20) down to the vicinity of the drum base (18) over the entire periphery and in drum longitudinal direction. A third upset surface flange may be provided as a bottom rolling ring (38) in the transition region from drum wall to drum base.

  • Patent number: 5460504
    Abstract: The invention relates to a storage head for a blow moulding machine for discontinuous manufacture of multi-layer co-extruded and blow-moulded hollow bodies made of thermoplastic. To improve the product quality and to increase the throughput, each distributor element is designed as a spiral channel distributor (20) which distributes the individual molten plastic streams uniformly at the periphery. The ejector (14) consists of at least two concentric tubular pieces (42, 44) and the peripherally distributed plastic flows from the ejector (14) through an annular gap (46) into the storage space (16) in the storage head housing (10) below the ejector.

  • Patent number: 5425454
    Abstract: The invention concerns a large-capacity stackable drum with a substantially cylindrical sidewall and top and bottom ends. To improve the stackability in particular the long-term stackability an internal hydrostatic pressure which supports the side wall is initially produced, when stacking several drums one on top of the other, in the gas space above the content and in the contents, of the drums stacked underneath, by virtue of the elastic flexibility of the top and/or the bottom of the drum, until a reduced stacking load acting through the top rim or grip ring of the drum into the drumwall is produced or support provided through the bottom rim or grip ring.
