Definitions

  • the invention relates to a lid barrel with a lid barrel body made of thermoplastic material, which can be closed gas and liquid-tight if necessary by means of a barrel lid and clamping ring for the storage and transport of solid or liquid filling goods.
  • the invention further relates to a new method for producing this lid barrel body.
  • Cover barrel bodies are usually produced in the blow molding process in a special split blow mold.
  • Modern lid drums have a compressed solid or stable jacket flange on the upper outer rim of the drum for supporting the drum lid and as a counter bearing for the clamping ring below.
  • the stable jacket flange is compressed directly from the material of the barrel body wall within the blow mold by means of a ring-shaped slide valve.
  • the waste pieces (slugs) are separated off at the squeezing areas of the tubular preform at the top and bottom.
  • the waste piece On the side of the filling opening of the barrel body, the waste piece consists of a cap-shaped ring part which was designed to avoid large amounts of waste around a blow mandrel with the largest possible diameter; this piece of cap is cut cleanly in the vicinity of the upset jacket flange.
  • a manufacturer of plastic drums for example only one blow molding machine is available, would like to meet different customer requirements and produce different drum shapes, drum sizes or products (e.g. sheet piles, lid drums, canisters etc.) on his machine. For this he needs a special blow mold for each product. Does the barrel manufacturer now want a product, e.g. a bung on another product, e.g. a cover drum, he must stop the blow molding machine and dismantle the sheet drum blow mold halves from the mold clamping plates and peripheral supply lines (such as for hydraulic oil, cooling water, thermostats etc.) and then remove the cover drum Put on the blow mold halves and reassemble the pipe connections. This causes comparatively long downtimes and the resulting failure costs on the blow molding machine.
  • a product e.g. a bung on another product, e.g. a cover drum
  • This object is achieved according to the invention in that a finished bung with an upper carrying and transport ring (handling ring) and with at least one bunghole opening in the top floor is used as the starting product and the barrel body of the lid barrel by cutting the top bottom out of the bung is manufactured in such a way that a filler opening with a large diameter is created, the carrying and transport ring remaining as a support for a correspondingly adapted drum cover and, if appropriate, as a counter bearing for an engaging clamping ring at the top of the drum body.
  • the cap-shaped upper waste piece at the filling opening was usually separated by an almost horizontal cut in the essentially axially extending barrel wall protruding above the outer jacket flange; the cutting edge is thus directly at the top of the barrel.
  • the lid barrel according to the invention is characterized by a striking, essentially axially running cutting edge or surface on the inside of the barrel wall or within the upper carrying and transport ring, with a distance (about 20 mm to 80 mm) below the upper edge of the barrel or the surface of the carrying and transport ring.
  • the carrying and transparent ring remains as a solid upper end on the lid barrel body, so that even a lid barrel body without a barrel lid (clamping ring or an empty barrel) has a handy handle ring and is easy to manipulate.
  • Another very important advantage of the new lid barrel is that it can be gripped and transported with the barrel gripper tools (parrot beak) common for steel bung barrels in the closed state with barrel lid and clamping ring as well as in the unlocked state without barrel lid.
  • barrel gripper tools parrot beak
  • special drum gripper tools are required, with which, however, sheet drums cannot be gripped or transported.
  • cover drums can be produced from newly manufactured sheet drums immediately or later (after intermediate storage or storage).
  • any used sheet drums can be used as starting products for a subsequent reworking into cover drums after their first use or multiple use (as a bung).
  • the measure according to the invention of converting used sheet drums into cut-out barrel bodies by cutting out the topsoil makes a very substantial contribution to reducing the current packaging volume and reducing environmental pollution.
  • the container thus reconditioned and converted into a cover barrel body is provided with a barrel cover with a cover seal corresponding to the cut-in large container opening and sealed gas and liquid-tight by means of a corresponding clamping ring.
  • This measure which is simple in itself, allows a previously closed container, such as a plastic sheet drum, to be used further as a cover barrel body or to be used for further industrial purposes.
  • the lid barrel produced in this way "from old make new" is particularly suitable for use with an inliner or film bag or plastic adjusting container if contact of the new filling material with the (used) possibly contaminated barrel wall is to be avoided.
  • lid barrel bodies made from old sheet piling in accordance with the invention in comparison with the production of a customary completely new lid barrel body.
  • a correspondingly adapted, separately prefabricated circumferential outer ring flange is glued or welded onto the cut-out top floor with at least one bunghole opening as a lid edge or as an upper counterbearing for the tension ring closure, so that the top floor of the bung can be used as a barrel lid for the lid barrel body.
  • the lightweight lid barrels manufactured according to the invention from sheet pans are particularly particularly suitable when used with inliners or thin-walled adjusting containers for the field of use of fiber drums.
  • FIG. 1 shows a broken longitudinal sectional view of a conventional plastic sheet drum with a high-level handling ring (prior art)
  • FIG. 2 shows a plastic cover barrel body according to the invention in a side view with a partial sectional view
  • FIG. 3 shows another conventional plastic sheet drum with an additional bottom roll ring ( State of the art)

  • reference numeral 10 denotes a large-volume plastic sheet drum for storing and transporting, in particular, dangerous and liquid filling goods with an almost cylindrical barrel wall 18.
  • At least one gas and liquid-tight closable bunghole opening 14 with a comparatively very small diameter is arranged in the upper floor 12 of the bung barrel 10.
  • the bung drum 10 On the upper outer circumference, the bung drum 10 has, in an almost axial extension of the drum wall 18, a circumferential carrying and transport ring 16 or handling ring for the use of mechanical drum grippers.
  • the drum grippers - for example on a forklift truck - have an upper and a lower drum gripper claw (parrot beak) and are suitable for plastic sheet drums with a raised handling ring as well as for conventional steel sheet drums.
  • the bung 10 from FIG. 1 has been simply removed from the top bottom 12 near the inside diameter of the upstanding handling ring 16 and, as shown in FIG. 2, an easy-to-clean lid barrel body 20 with a large upper filling opening is obtained 32, which is now also suitable for the use of solid filling goods.
  • this cover barrel body 20 has a striking cut edge 30 on the inside of the barrel wall 18, along which the top floor 12 of the former bung barrel 10 was separated.
  • FIG. 3 shows another bung 42 with a bottom roller ring 44, which is also suitable as a starting product for the production of a lid barrel.
  • the sheet pans can be produced in various ways.
  • sheet drums are manufactured in one piece using the blow molding process.

So a barrel body with a bottom e.g. be produced in the blow molding process, then an upper base, prefabricated by injection molding, with an integrated hand ring is welded onto this barrel blank.
  • FIG. 4 shows an enlarged partial section of a bung barrel (10, 42).
  • the carrying and transport ring 16 is formed in a direct axial extension of the barrel wall.
  • the carrying and transport ring 16 has an almost horizontal contact surface 46 that is accessible from below on the outside and an almost vertical contact surface 48 that is accessible from above on the inside.

  • the connection point or the engaging groove 54 formed there for the upper barrel gripper claw lies with its groove base at a distance below the level 58 of the horizontal contact surface 46 of the carrying and transport frame 16.
  • the cover barrel body 20 shown in FIG. 5 has been created by separating the top shelf 12 from the bung 42 according to FIG.
  • the cut edge 30 lies on the inside of the barrel wall 18 at a distance below the height plane 48 or even further below the top edge 56 of the barrel, which is formed by the surface of the carrying and transport ring 16.
  • a lid barrel body 20 according to the invention is completed with a barrel lid 24 made of hard plastic and a clamping ring 26 to form a lid barrel.
  • An annular seal 34 is inserted into the edge of the barrel cover 24, which seals the barrel cover 24 against the beveled sealing surface 60 of the carrying and transport ring 16.
  • the sealing surface 60 is expediently located next to the top edge 56 of the barrel, since this is already in use, for example, when a barrel body is used, and can possibly have damage such as scoring or scratches.
  • This embodiment is suitable, for example, in combination with an inliner (film bag) for viscous fillers.
  • the lid barrel body 20 is provided with a barrel lid 62 made of sheet steel, which is fixed on the carrying and transport ring 16 in a gas-tight and liquid-tight manner by means of the overlapping clamping ring 26.
  • This version of the lid barrel is particularly suitable, for example, in combination with a thin-walled but stable adjustment container for low-viscosity fillers.
  • FIG. 8 Another embodiment with a self-locking snap cover 64 made of plastic is shown in FIG. 8. No clamping ring is required for this cover.
  • the lower edge of the snap cover 64 is segmented and provided with radially inwardly projecting latching cams 66 which, in the closed state, automatically engage under the essentially horizontal contact surface 48 of the carrying and transport ring and fix the cover.
