Abstract

A plastic barrel for storing and transporting liquid, granular and pulverous materials. The barrel includes a conical, stackable barrel body and a closing cover for the upper filling opening. The wall of the barrel body has in the area of the bottom of the barrel inwardly directed stacking cams which are formed from the wall of the barrel body and are provided with support surfaces for supporting the barrel bottom of another barrel body stacked in the barrel.

Description

TONE OF SYNTHETIC MATERIAL DESCRIPTION OF THE INVENTION The invention relates to a cask of synthetic material for the storage and transport of contents in the form of liquids, granules and powders, which has a conical barrel body, capable of being stacked, and a closing lid for the upper filling opening. This type of barrels and barrels are generally known. Large volume containers of the type under consideration with a conical shape are characterized by the advantage that as an empty product they can be stacked one inside the other and thereby result in low storage costs and, in particular, low transport costs. · In the transport of the conical barrels stacked one inside the other there is a risk that, by virtue of the vibration movements, they get stuck in such a way that it becomes difficult to remove the individual barrels from the pile after transporting them. . The same problem occurs in the case of storage of conical drums. The wide-necked steel barrels known from EP 0 471 918 Al are provided in the lower base with a shutter opening which is sealed to liquids by a cover, which offers the possibility: that through the The runner opening is inserted into the base of the barrel stacked underneath an auxiliary element, such as an extraction device or a working spindle, so that an operator can push out with little effort, without damaging it, the internal stacked barrel that is stuck The separation of a larger stack of barrels in this way continues to present difficulties. The object of the invention is to produce a conical cask of synthetic material that can be removed from the stack in an easy and damage-free manner. This problem is solved according to the invention by means of a barrel of synthetic material having the features of claim 1. The dependent claims contain advantageous and convenient refinements of the invention. The conical tub of synthetic material according to the invention is characterized by the advantage that, by means of stacking cams with resting surfaces facing inwardly which conform to the wall of the barrel body in the region of the base to support the The barrel base of a barrel body stacked inside, when stacked one inside another the barrels are interstices between the walls themselves, so that the barrels can not be jammed and by this it is possible, without difficulties, to remove from the pile the barrels The. invention is explained below on the basis of the drawing figures, which represent the following: Fig. 1 an exploded representation of a barrel of synthetic material, Fig. 2 a top plan view of the open barrel, Fig. 3 a section longitudinal of the barrel cover area in amplified representation, and Fig. 4 a longitudinal section through the lower region of a stack of 4 barrels. Cask 1 made of synthetic material blow molded from; according to FIGS. 1 to 3, which preferably is used as a water barrel, comprises a conical barrel body 2 that is subdivided into six annular segments 3-8, whose diameter increases in a staggered manner from the lower base 9 of the barrel to the barrel. upper filling opening 10, which is closed with a closing lid 11. The closure lid 11 is fixed with a bayonet closure 12 on the body 2 of the barrel. On the wall 13 of the barrel body 2, in the region of the lower base 9 of the barrel, four prismatic stacking cams 14, facing inward, are formed, which have a triangular resting surface 15 for supporting the barrel base 9 a barrel body 2 stacked inside. By means of the stacking cams 14, gaps 16 are conserved between the walls 13 of the barrels 1 when stacking one another into several barrels, so that the barrels 1 can not be stuck, and thus it is possible to remove the barrels from the stacks 1. stack without difficulties- (Fig. 4). On the 13th barrel wall, in the base region 9 of the barrel is disposed a discharge opening 17 with internal thread, which can be closed with a screw cap 18. The :. closure lid 11 of barrel 1 of synthetic material, which is reinforced by radially extending reinforcing ribs 19 which are formed therein having an opening; 20 central that can be closed by a lid 21 and a clamping ring 22. In the central opening 20 of the closing lid 11, for example, the end of a downpipe of a drainage channel of the roof of a house can be inserted. By using the water barrel 1 in agriculture there is the possibility of intermixing the water with additives, for example, chlorine additives through the opening 20 of the lid.

In a form that differs from the described embodiment of the barrel 1 of the synthetic material, it is possible that a central runner pipe with a runner that can be closed with a runner plug is formed in the closing cover 11.
