Description

Plastic barrel.

The invention relates to a plastic barrel for storage and transportation of fillers liquid, granulated and powdery, with a barrel body stackable, conical, which is divided into annular segments, whose diameter increase stepwise from the bottom of the barrel to the top loading opening, and with a closing lid for the top loading opening.

The container known from WO 95/25054 A, with a conical shape in the manner of the exposed genus, is characterized by the advantage that, as empty containers they can stack one inside the other and thus lower costs of warehouse maintenance and especially lower costs of transport.

In the transport of stacked conical barrels one inside another there is the danger of, that due to the movements of rattling seize each other in such a way that after the transport difficulties in unstacking the barrels individual. The same problem occurs in the storage of conical barrels

WO 95/25054 A describes a container plastic sterilization, especially for waste from sanatorium, with a lid that is held by a tension ring over the container, which consists of several stretches that narrow in diameter from top to bottom, which make possible a stacking several containers inside each other. On the stretch lower and on the bottom of the container are arranged ribs distanced on the periphery, which run on its inner wall up from the inside of the bottom of the container and increase in radial thickness. The nerves serve to support the container bottom of another container stacked in a container, as well as for the reinforcement of the container against the pressure of the hot steam produced by the container for sterilization of pollutant or health-threatening wastes.

The nerves of this sterilization vessel known have a narrow upper support edge, so that a plurality of nerves is required for stacking a container. In addition, the container can only be manufactured as plastic injected casting vessel due to plurality of supportive nerves and is expensive in correspondence.

For the document US-A-4 082 184 turns out a container plastic conical, which is divided into a cylindrical container top, five other segments and a bottom segment, decreasing staggered the diameter of the segments from the opening top load to the bottom of the container and being configured the slightly tapered segments and molded the somewhat thicker bottom segment, so that the container can Unmold without difficulty from a manufacturing mold. The steps in staggered mode between individual segments are formed in each case by an outer conical seat and an inner one. At stacked one inside another of several containers, it rests on each case the inner stacked container with conical seats exteriors of the individual container segments of the outer container, stacked under. In the inner wall of bottom vessel segment are formed three supports triangular distributed on the periphery of it. At stacked one inside another of several containers, in each case inner container is supported with the outer conical support, in the lower edge of the lower vessel segment, over the three brackets on the inner wall of the lower vessel segment of in each case outer container. The brackets have the function of adjusting the containers fitted against each other, of so that the outer seats of the container segments of the in each case inner container limit with the seats inside the container segments in each case outer container

This container has the disadvantage that containers stacked on each other are seized in the seats interior and exterior of individual container segments, so that unpacking of the containers causes difficulties.

Object of document DE 381 407 C is a box of rectangular shipping in the shape of a pyramid trunk, with a wooden lid for the transport of fruit, whose four walls widen from the bottom towards the upper edge. For stacking one in another of several empty boxes are installed at the bottom of box four wooden corner studs with a prismatic shape, serving as supports for the funds of the boxes stacked in one another.

The wooden box has the disadvantage that several boxes stacked one on another, whose walls are closely together, they seize each other and thus the unstacking the boxes causes problems.

The mission of the invention is based on developing a plastic conical barrel that can be easily unstacked and without damage.

This mission is solved according to the invention by a plastic barrel with the features of the claim.

The conical plastic barrel according to the invention is characterized by the advantage, that by the stacking cams with Support surfaces for supporting the bottom of a barrel Stacked barrel body, directed inward and molded into the bottom area in the barrel body wall, slits remain in the stacking of the barrels between the walls thereof, so that the barrels cannot be seized and in this way the barrels They can be dull without difficulties.

The invention is explained in what follows with the help of the figures in the drawing, which represent the following:

fig. 1 an exploded view of a plastic barrel,

fig. 2 a plan view from the top of the open barrel,

fig. 3 a longitudinal section of the area of barrel cover in augmented representation and

fig. 4 a longitudinal section through the area bottom of a 4 barrel stack.

1 barrel blow molded plastic according to figures 1 to 3, which is preferably used as a barrel of water, it has a conical body 2 barrel, which is divided into six annular segments 6-8, whose diameter increases staggered from the bottom 9 of the barrel to the opening top 10 load, which can be closed with a closing lid 11. The closure lid 11 is fastened with a bayonet closure 12 on the 2 barrel body.

On the wall 13 of the barrel body 2 are molded four stacking prismatic cams 14, directed towards inside, with a triangular support surface 15 for support from the bottom 9 of a barrel of a body 2 of stacked barrel. By stacking cams 14 remain in the stack one inside another of several barrels 1 grooves 16 between the walls 13 thereof, so that the barrels 1 cannot be seized and thus the barrels 1 can be dull (fig. 4) without difficulties.

In the barrel wall 13 it is arranged in the barrel bottom zone 9 a discharge opening 17 with a internal thread, which can be closed with a screw cap 18.

The closing lid 11 of the plastic barrel 1, which is reinforced by stiffness ribs 19 formed in it that run radially, it has a central opening 20 that can close with a cover 21 and a tension ring 22.

In the central opening 20 of the closing cover 11 for example the end of a gutter of a channel can be inserted of roof of a house. In the use of water barrel 1 in the agriculture there is the possibility of adding supplements to the water by the lid opening 20, for example chlorine supplements.

Departing from the described embodiment of the plastic barrel 1, in the closing lid 11 may be formed a short central spike tube with an opening of spike, which can be closed with a spike plug.
