BACKGROUND OF THE INVENTION The invention relates to a barrel made of thermoplastic barrel, axially extended from the barrel to the barrel bottom, extending axially between the barrel and the barrel extending radially from the barrel casing to the barrel casing. Such is disclosed, for example, in EP 88 100 868. notification.

Conventionally, the barrels are provided with a robust, cross-sectional, carrier and transport ring near their end surface, having a horizontal and a vertical contact surface for a barrel gripping tool.

In most cases, these barrels are made by a blow molding process in which these support and carrier rings are formed integrally with the barrel during manufacture. However, barrels are known in which the tubular barrel part and the end region of the barrel are made separately. The end ranges made by injection molding are welded to the barrel in a separate session with the support and bearing rings thereon. Plastic barrels with such three prefabricated and welded parts are known, for example, from DE-GM 8 631 318. description.

Given that such a barrel falls from a certain height and the support and support ring is inclined obliquely to the ground, it is endangered by the relatively thin wall thickness, and therefore a so-called barrel is placed in front of the support and support ring. a crumple zone should be created to absorb the energy generated in the collision. This is done so that the ring is at a certain distance from the head and bottom and the barrel extending beyond the groove of the ring is tapered relative to the barrel axis.

In an oblique or vertical collision, the end regions of the elastic barrel above the ring are deformed.

Due to the relatively small distance of the ring from the barrel head or bottom, the barrel can be rolled in an oblique position. it is easy to grip, which allows favorable barrel movement.

In the case of a barrel full of oblique positioning, the bottom of the barrel is pressed flat by the weight of the barrel, thus causing disturbing effects. By supporting the support and bearing ring, deformation at the bottom can be partially eliminated and also its adverse effect.

Despite this, rolling the barrel is still very difficult. In addition, the transition of the edge region into the barrel jacket is relatively thin at the bottom of the barrel and may result in overload when slanting. In addition, the risk of an accident increases when the barrel is tilted or when the barrel is rolled up with a rolling ring.

Since only the upper support and carrier ring serves as a support surface for the barrel holder, the lower support and carrier ring can be provided for other functions. However, for this to be taken into account, the deformation forces are also considered when the filled barrel falls.

For this purpose, the lower support and carrier ring must be converted into a rolling ring, which occupies a slightly different position on the barrel casing.

This is accomplished in accordance with the present invention such that the cross-section of the rolling ring has an approximately trapezoidal shape and the narrowest position of the rolling ring is in the region of the groove bottom and the thickness of the rolling ring gradually increases from this end to the end surface of the barrel bottom.

In this way, the barrel can only be rolled on the roll ring.

In the case of a barrel obliquely or vertically colliding, the collision energy is absorbed directly by the rolling ring, which, at a narrow connection point, bends inwardly towards the barrel shell and is elastically deformed until it rests on the conical shell portion. Thus, the impact energy is absorbed by the deformable rolling ring.

The forces exerted on the vertical stacked barrels are absorbed by the rolling ring and the bottom of the barrel, while the force is distributed through the cylindrical casing. The end surface of the barrel bottom can be bounced axially relative to the rolling ring to provide a perfectly good rest on the ground.

When rolling, the transverse load according to the invention can be better absorbed in that the rolling ring is slightly inclined starting from the groove bottom, while the center axis displaced by the ring cross-section intersects the center of gravity of the barrel. In this way, the roller ring is largely protected from bending stress, and the storage forces are transmitted directly to the barrel shell by the roller ring.

By making the outer diameter of the end face of the rolling ring equal to the largest diameter of the barrel shell, an economical palette of the barrel can be ensured.

Finally, according to the invention, it may be advantageous for the rolling ring to be immersed in a narrower cross-section at its outer and inner regions with uniformly distributed ribs.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail with reference to the drawing, wherein:

Figure 1 is a side view of a barrel, while

Figure 2 is a larger sectional view of the barrel head, and a

Figure 3 is a larger sectional view of the bottom of the barrel.

In the figures, the cylindrical portion of the barrel 4, the end surface of the head 10 and the end surface of the bottom of the barrel 7 are indicated.

In the vicinity of the barrel head, a strong transport ring 11 is formed with a horizontal bearing surface 13 and a vertical receiving surface 14 for the handle of the barrel not shown.

The transport ring 11 is formed integrally with the barrel jacket 4 by the connecting ring 15 which is connected to the horizontal bearing surface 13.

The groove bottom between the connecting ring 15 and the conical portion 12 rising conically to the head end surface 10 is, in this embodiment, located at a distance below the horizontal bearing surface 13 of the transport ring 11.

The roller ring 1 formed in the barrel bottom region has an approximately trapezoidal cross-section. The narrowest point of the scroll ring 1 is at the groove bottom 2. In addition to improved weldability, a certain weakened part is formed here so that the roller ring 1 can be bent inward in the event of lateral deformation forces. Starting from the narrowest point, the scroll ring 1 rises to the thickened end region.

The end surface 5 of the roller ring 1 ends in the plane of the base 7 of the barrel, which passes through the conical portion 6 into the cylindrical portion 4. The diameter of the end face 3 corresponds to the cylindrical diameter of the barrel jacket.

The roller ring 1 is inclined slightly conically outward from the groove bottom 2. The continuation of the dotted centered center axis 8 across the annular cross-section intersects the center of gravity of the barrel 9, not shown.
