Definitions

  • the invention relates to a blow molded thermoplastic barrel with barrel jacket, molded barrel bottom, molded barrel cover, ventilation bung training and filling and emptying bung training, the bung training are arranged in the barrel lid and a handling ring is connected to the barrel jacket in the region of the barrel lid, this Handling ring has a collar that surrounds or projects above the sheet formations at the same level, and a handling ring is connected to the barrel jacket in the region of the barrel bottom.
  • the ventilation bung education and the filling and emptying bung education are provided with appropriate bung caps and / or bung valves.
  • Barrels with a barrel jacket, molded barrel bottom, molded barrel lid, ventilation bung formation and filling and emptying bung formation, the bung formation being arranged in the barrel lid, that are produced by blow molding are known in various embodiments.
  • the sheet formations lie in cover recesses.
  • the handling rings are integrally formed, namely with respect to the drum cover or the drum base, offset towards the middle of the drum (cf. DE 37 07 724 A1, DE-GM 87 05 915).
  • the measures known so far, particularly for mass production, are complex in terms of production technology and can be improved with regard to the so-called full emptying behavior.
  • the bung designs protrude above the level of the drum lid. On the barrel bottom and the barrel lid in the transition area between the barrel bottom and the barrel lid on the one hand and the barrel jacket on the other hand with overhanging handling rings protruding upwards. They also support the sheet piling.
  • the document DE-U-7440181 discloses a barrel molded by blow molding from thermoplastic material with barrel jacket, molded barrel bottom, molded barrel lid, ventilation bung formation as well as filling and emptying bung formation, the bung formation being arranged in the barrel lid and a handling ring being connected to the barrel jacket in the area of the barrel lid, this handling ring having a collar that points the bung formation upwards surrounds or towers at the same level, and a handling ring is connected to the barrel jacket in the region of the barrel bottom.
  • the invention has for its object to further design a barrel formed by blow molding from thermoplastic material of the basic structure described at the beginning such that it can be easily manufactured as a mass product and preferably has a very good full emptying behavior.
  • the invention is based on the knowledge that the manufacture of a barrel of the type described above basic structure can be considerably simplified by blow molding if the handling rings are not molded on by blow molding, but are designed as independent components and are subsequently connected to the blow molded barrel body.
  • the connection can be made in a form-fitting manner by means of corresponding form-fitting elements or also materially by welding. With this type of production, the barrel body can be shaped without difficulty so that a very extensive full emptying takes place.
  • the barrel 1 shown in the drawing consists of thermoplastic material and is shaped by blow molding.
  • the basic structure includes the barrel casing 2, a molded barrel bottom 3, a molded barrel cover 4, a ventilation bung formation 5 and a filling and emptying bung formation 6.
  • the bung formation 5, 6 are arranged in the barrel cover.
  • a handling ring 8 with an L-shaped cross section is connected to the drum casing 2.
  • a handling ring 8 with an L-shaped cross section is connected to the barrel jacket 2 in the region of the barrel bottom 3.
  • the arrangement is such that the handling rings 8 have an L-foot flange 9 which is arranged in the region of the barrel jacket 2 and projects freely outwards.
  • the arrangement is also such that the handling rings 8 have an L-web collar 10, which surrounds or surmounts the sheet formations 5, 6 upwards and the recess 7 in the barrel base 3 downwards at the same level.
  • the drum cover 4 has a circumferential collecting channel 11 which is concave to the interior of the drum and projects above the level of the drum cover 4.
  • the collecting trough 11 has the sheet formations 5, 6.
  • the arrangement is such that the collecting trough 11, with barrel 1 rotated through 180 °, has its lowest point in the area of the filling and emptying bung 6, which is not very clearly visible in the drawing for reasons of scale.
  • the training is also such that the barrel cover 4 drops when the barrel 1 is rotated through 180 ° toward the collecting trough 11 as a run-off slope.
