  • Patent number: 6024237
    Abstract: A pallet container (10) has a thin-walled plastic container (12), a support casing (14) made of a wire grating and a bottom pallet (16). In order to improve the falling resistance of such a pallet container (10), some of the vertical rods (18) that form the wire grating of the support casing (14) are prolonged, extend through bores (20) provided in the bottom pallet (16) and are screwed from below against the bottom pallet by a screw nut (28).

  • Patent number: 5975338
    Abstract: The invention relates to a bung drum of thermoplastic synthetic material, having a circumferential carrying and transport ring disposed on the drum wall in the vicinity of the upper end and having at least one bung hole located in the edge region of the upper end. The upper end of the drum has a slope surface on both sides of the bung hole. When seen in the normal position of the barrel, the slope surface slopes downwardly in the direction of the edge of the drum with its lowest point in the vicinity of the bung hole.

  • 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: 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.

  • Patent number: 5201437
    Abstract: A widemouthed, open topped steel drum of conical shape, having a large filling and emptying opening capable of being closed, in liquid-tight condition, by means of a lid and a tension ring. The sidewall of the drum has an encircling bead which, upon nesting of two empty drums, rests on the top edge of the drum beneath. The bottom of the drum has at least one closeable bunghole through which the upper drum can be engaged to remove it from the lower drum of a stacked pair.
