Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a barrel stopper made of thermoplastic synthetic resin, comprising:
The supporting and carrying ring in a broad sense has an internal support and carrying ring placed on the barrel peripheral wall near the end face of the barrel to which it belongs;
Equipped with horizontal and vertical self-supporting surfaces for applying the chuck arm of the S gripping device! , -shi, and the supporting and carrying ring is in contact with the horizontal abutting surface a L
and is integrally connected to the barrel via a connecting ring that is continuous with the barrel peripheral wall, and the peripheral wall portion that protrudes from the ring-shaped groove formed by the connecting ring protrudes in a conical shape toward the barrel end surface. Regarding the format of

BACKGROUND OF THE INVENTION The barrel plug hole is manufactured entirely by blow molding method,
Although it is primarily intended for those in which the supporting and conveying ring is integrally molded from the brown peripheral wall during construction, barrel plug holes are also known in which the tubular barrel peripheral wall and the barrel end area are manufactured separately from each other. be. The end region produced by injection molding and provided with a supporting and carrying ring is welded to the tubular body in a separate operation.

Such supporting and conveying rings generally have a cross-section surface with horizontal and vertical webs, as disclosed in German Utility Model Registration No. 7600621 FA. The vertical webs have their free ends directed toward the head surface of the barrel, and the horizontal webs are directed radially outward from the barrel peripheral wall. According to such a configuration, it is difficult to successfully weld the problematic @joint area, so conventionally, the problematic welding area is not exposed to bending force and the ring is made elastic in the circumferential direction. The support and conveyance ring is configured such that the support and conveyance ring deforms relative to the cask wall when exposed to percussion loads and the connection between the support and conveyance ring and the cask circumference increases. The department was structured in a flexible manner. For this purpose, the supporting and conveying ring was connected to the barrel via a ring-shaped connecting web that was connected to the horizontal abutment surface and continuous with the barrel circumferential wall.

The ring-shaped connecting web is therefore only loaded by harmless tensile loads which are introduced into the barrel circumferential wall when the barrel is supported and transported by the barrel gripping device.

If the ring-shaped connecting web of the support and conveyance ring is continuous with the barrel circumferential wall at an acute angle to the hood, in order to ensure the connection is as elastic as possible, the support and conveyance ring is The bottom of the groove between the ring and the adjacent conically raised circumferential wall portion ends at the same level as the height of the mounting surface at the horizontal level of the ring. This not only makes the violet of the curve between this horizontal height plane and the conical circumferential wall of the barrel very narrow (but also makes it possible to remove another noodle that has been added to the filling). The stacking force generated on the two end faces during stacking is directly introduced into the peripheral wall of the remaining barrel via the conical bulge.Such a configuration is disclosed in German Patent Application No. 3526921/IW. ing.

Problem to be Solved by the Invention In this way, by narrowing the chamber between the dipping surface and the conical peripheral wall portion of the barrel in a horizontal sushi gripping device d.
is difficult to use, so the gripping device must be given a special shape. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a barrel bung hole which allows any barrel gripping device to be used, in particular also for barrels constructed from a firewood board.

Means for Solving the Problems According to the invention, the groove bottom between the connecting ring and the circumferential wall portion that rises conically towards the barrel end region is formed in the supporting and carrying ring. Spaced below the horizontal abutting surface, said connecting ring is integrally molded from an axial extension of the cylindrical barrel circumferential wall.

Effects and Effects This arrangement provides sufficient space for the barrel gripping device of the boat fishing, so that the upper gripping arm can be attached to the foil bearing surface of the support and carrying ring. It can be avoided to be installed behind the It is also ensured that the radially outer edge of the support and conveyance ring remains unchanged. This is because this is a prerequisite for stacking barrels.

Additionally, the increased chest space significantly reduces manual handling.

The groove bottom between the supporting and conveying ring and the circumferential wall section has a special advantage due to the lengthening of the connecting ring compared to previous proposals in which the bottom of the groove ends in the level plane of the mounting surface with a horizontal foil. As a result, a better elastic connection is achieved in the circumferential direction to the outer circumference of the barrel.

By increasing the height of the connecting ring according to the invention, a uniform wall thickness is obtained in the cylindrical region of the peripheral wall, in the adjacent region of the peripheral wall section which rises conically with respect to the end face, and in the region of the connecting ring. It will be done.

In particular, the wall thickness of the connecting ring is reduced as much as possible, thereby making it more flexible, so that when a barrel filled with filling is dropped laterally, all affected wall traverses Since a uniform deformation stress is generated on the surface, there is no undesirable tip stress that may cause material cracking.

Moreover, when the barrel is dropped laterally, the rotational stroke of the ring part that hits the floor is shortened in the deformed position, which in turn reduces the angular change applied to the transition part of the connecting ring to the cylindrical material part. become smaller. Due to the reduced shape change stroke and shape change angle, material stress is reduced.

According to the invention, it is further provided that the end face of the barrel ends below the horizontal, still-standing surface of the support and conveyance ring, and that the height of the conical outer circumferential area of the support and conveyance ring is It corresponds to at least the height of the ring. This ring height must be maintained to provide sufficient flexibility when the filled S is dropped laterally.

In order to obtain a so-called crushing zone in which the main impingement force is absorbed, it is advantageous to provide a region of material rising from the annular groove and rising towards the end face. This means that the groove bottom of each support and transport ring is 9II below the surface where the water XF is applied.
It is obtained by arranging it at an interval of mJ from I. The height of the conical material region with a continuous head end surface can extend up to and beyond the upper edge surface of the support and conveyance ring. If the end surface of the barrel is placed below the horizontal abutting surface of the support and conveyance ring, as mentioned above, the minimum width of the conical peripheral wall should be at least equivalent to the height of the support and conveyance ring. must be done.

Going slightly below this height is done in lightweight barrels where a sufficient crushing zone is maintained.

Embodiment Near the end face 6 of the barrel, an internal support and carrying ring 1 is provided. This support and carrying ring 1 has a horizontal abutment surface 2 and a vertical abutment surface 3 for the gripping arm (not shown) of the barrel gripping device. The upper edge surface of the support and conveyance ring 1 is flush with the barrel end surface 6 in FIG. 1 and projects beyond the barrel end surface 6 in FIG. 2 relative to fL. The support and conveyance ring 1 is integrally connected to the outer circumference of the barrel via a connecting ring 4 which is connected to a horizontal foil dressing surface 2 . w: The bottom of the groove between the continuation ring 4 and the circumferential wall portion 5 which rises conically towards the barrel end face 6 is spaced below the mounting face 2 by a horizontal foil of the support and conveyance ring 1. It is located.

As shown in FIG. 2, if the barrel end surface 6 ends below the horizontal contact surface 2 of the support and conveyance ring 1, the height dimension of the conical peripheral wall portion 5 will be at least This corresponds to the ring height dimension of the support and transport ring 1.

On the one hand, the conical shape is necessary to ensure the required space for the use of the barrel gripping device, and on the other hand, the minimum height of the so-called crushing zone is limited between the barrel end face 6 and the barrel peripheral wall 1.
Serves as a necessary elastic lock between.

As shown in Figure 6 +fC, the barrel end face 6 is outside 11i.
1 It is uniformly curved towards iC.

At the bottom of the connecting ring 4 a channel 8 is arranged for draining water. The groove bottom extends in an undulating manner around the circumference of the barrel, and one or more channels 8 are provided such that they are always located within this undulating groove bottom.
