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.

• 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.

• 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.

• the drum lid 24 is in turn held in the closed position by a clamping ring 26; the cover seal 34 is pressed against the sealing surface 60 and the semi-circular sealing strip 72 on the carrying and transport ring or is prestressed in a gas- and liquid-tight manner.
• the drum cover 24 is supported radially on the inner wall of the cover drum body or is centered by abutment on the essentially vertical bearing surface 48 of the carrying and transport ring 16 or the region of the inner drum wall located underneath.
• This lid barrel can also be gripped and transported with a barrel gripper tool, which is otherwise only suitable for conventional sheet drums, since it is ensured that the top barrel gripper claw can engage in the barrel lid from the inside without interference up to at least level 58 of the horizontal contact surface 46.
• a lid barrel body 20 in which a support edge 76 has been left behind the cut edge when cutting out the bung top surface, it is equally suitable - as shown in FIG. 12 - after inserting the filling material with one welded onto the support edge 76
• Barrel cover 80 to be closed gas-tight and liquid-tight as a weld-on cover.
• the weld-on cover 80 has an outer diameter of the same size or slightly smaller than the inner diameter of the barrel opening above the supporting edge 76.
• the carrying and transport ring 16 serves as a support and sealing surface for the attached barrel cover 24 with an inserted sealing ring 34.
• the carrying and transport ring 16 also serves its lower, almost horizontal contact surface 46 for the lower drum gripper claw 40 of a drum gripper as a counter-bearing for an overlapping or underneath clamping ring 26.
• the upper floor 12 cut out of the former bung barrel with a bunghole opening 14 can advantageously be provided with a separately prefabricated ring flange 28 be provided, and is processed in this way to a usable drum lid 24.
• the comparatively thin ring flange 28 is welded or glued to the bung top upper floor (12) 24 along the circumferential welding zone 32 and its cross-sectional shape is adapted to the upper cross-sectional shape of the carrying and transport ring 16.
• the barrel cover 24 or ring flange 28 is drawn in a little inwards or downwards - at least to below the level 58 of the horizontal contact surface of the carrying and transport ring 16 - running parallel to the barrel wall. This results in the barrel cover 24 an engaging groove 36 with an almost vertical contact surface for engaging the upper drum gripper claw of the special drum gripper, which is otherwise only suitable for sheet drums.
• the lid barrel body 20 is shown with a flat barrel lid 24.
• the drum lids used can generally be e.g. made from sheet steel (approx. 1.5 to 2 mm thick) or from injection-molded thin-walled plastic (approx. 2.5 to 3 mm thick).
• the plastic flat lid 24 shown here is preferably used in the lid barrel body 20, particularly when using thin-walled plastic adjusting containers or foil bags (inliners).
• a barrel lid 24 with an engaging groove 36 is placed on the lid barrel body characterized by the cutting edge 30 and by means of the U-shaped clamping ring Ges 26 clamped gas and liquid tight on the sealing surface on top of the carrying and transport ring 16.
• the lower load-bearing drum gripper claw 40 bears against the lower horizontal contact surface or on the lower leg of the clamping ring 26, while the upper drum gripper claw 38 engages in the engaging groove 36 of the drum cover and thus, so to speak, simultaneously into the filling opening 22 of the cover drum body bears on the vertical contact surface.
• a lid barrel closed and filled with a lid for example with a weight of 220 kg
• an empty unlocked lid barrel body can be gripped and handled by means of the barrel gripper.
• any bung barrel embodiments are cut to cover barrel bodies according to the invention by cutting out the top or even by cutting off the entire barrel head or also trimming existing peripheral rings and with an adapted barrel cover, optionally also with a tension ring. can be completed to a lid barrel.
