Description

Plastic barrel "" '

The innovation relates to a blown plastic barrel with a barrel lid, which is at a distance below the barrel opening has a self-contained, outwardly directed flange ring formed directly from the barrel jacket, against which the outwardly angled outer edge flange of the The lid placed on the opening neck of the lid rests in the event of an external axial load, with an over the inner edge of the lid protruding from the deep-drawn lid base against the opening neck, and a sealing ring inserted between the inner and outer edge of the lid against the upper edge of the Opening neck over one of the flange ring of the fcsses and the Lid outer flange encompassing clamping ring is pressed.

Such barrels can be palletized upright when full and stacked in columns without deformation and leaks in the barrel-lid connection are to be feared. The seal between the lid and the barrel can also be used cannot be crushed or displaced from their seat in the event of a strong increase in axial load from the outside, as the insertion path of the Cover through the flange ring of the barrel, which is attached to the outer edge flange of the lid is opposite, is blocked. The clamping ring holding the lid on the flange ring of the barrel prevents a lifting of the lid from its sealing position when the internal pressure of the barrel increases.

However, should such barrels be stored horizontally or closed horizontally several layers are stacked on top of each other, then leaks occur in the closed position of the lid, because the jacket area, which is even reinforced by the massive flange ring and the subsequent opening of the barrel will be at partial radial load deforms and pulls thereby out of its sealing seat on the drum cover.

With a certain barrel filling, storage of the However, a barrel is a prerequisite for the maintenance of the product. Fish, for example, are put in shipping drums together with brine stored. The barrels made of wood must be stored horizontally so that the fish are always washed around by the brine. For this purpose, each is at certain intervals To twist the barrel around its longitudinal axis.

Between each barrel layer when they are stacked on top of each other Barrels are placed in each row of barrels with two planks that cross the longitudinal axis of the barrel in the top and bottom area. In order to twist barrels * for the purpose of washing the fish, the Barrel layers repacked from top to bottom and stacked again after changing the rotational position.

Since metal barrels are not used for fish storage and shipping wooden barrels are used because they reduce the partial radial pressure when stored and stacked horizontally withstand and do not attack the filling. The production of such wooden barrels is expensive and the preparations for Filling, because the barrels have to be watered beforehand for the purpose of tightness. The possibility of using them is also a disadvantage only as one-way container. There is also the risk of breakage when filled wooden barrels fall out of the stack or connected particularly large in rough operating conditions.

The task at hand is to equip plastic barrels of the type described at the beginning so that they can be stored horizontally and is possible without the risk of leakage at the pressures that are partially acting laterally on the barrel jacket. Also is the lying one Stacking of filled barrels in several layers on top of each other even with a high specific surface load due to those pushed in between Planks desired. This makes use of the reusability Food-friendly plastic barrels of a conventional type with a capacity of 120 liters and more,

There should be at least four layers of filled barrels on top of each other be possible over longer periods of time.

These objects are achieved according to the invention in that the non-deformable one which is immersed in the opening neck of the barrel Inner edge of the lid supports the rigid radial support of the Flange ring of the barrel forms, with the Oeckelboden dipping below the flange ring surface in the barrel opening and between the bottom of the lid and the inner edge of the lid over the inner circumference of the cover star-shaped molded stiffening ribs are provided.

For particularly resistant reinforcement of the cover in ί embodiment of the invention, the lid 1st inner edge on the lid \ 'ground after extended downward and formed concentrically to the extension of a second annular projection on the lid base, wherein both ring projections have protruding from the lid bottom radial ribs to a circumferential box beam connected to each other,

In the drawing, an embodiment of the innovation is for example shown.

It show: C

Figure 1 shows a barrel with an attached lid in side view, partially | wisely trimmed, and ■

Figure 2 shows the barrel section according to Figure 1 in an enlarged version *

In the figures, the barrel 1 is closed with the cover 2. Immediately out of the barrel jacket, at a distance below the barrel opening, is the self-contained, radially outwardly directed one Flange ring 5 formed. The opening neck rising above the flange ring 5 is denoted by 9 (rig. 2).

When the cover 2 is in place, the flange ring 5 follows
outside angled outer edge flange 4 of the lid outer edge 14
opposite to. In the space between the outer edge of the lid 14 and
Inside edge 6 of the cover, the sealing ring 7 is inserted with that of the cover 2 against the upper edge of the likewise in the space
«Immersed barrel neck 9 is pressed sealingly via the clamping ring 8. The clamping ring 8 comprises the conical underside of the
Hanschringes 5 and the likewise conical upper side of the outer edge flange 4. If there is an axial load from the outside, the insertion path of the cover 2 is above the flange ring! blocked so that the Oichtring 7 cannot slip or be damaged.

The deep-drawn lid base 3 dips below the flange ring surface into the barrel opening. The lid inner edge 6 is
Designed to be dimensionally stable and forms an unyielding Radialabstlitzung of the flange ring 5, so that when a radial load occurs on the barrel 1 no change in the sealing position can occur. Lid base 3 and lid inner edge 6 are connected to one another via star-shaped reinforcing ribs Io.

The lid inner edge 6 is above the lid base 3 downwards
an annular projection 12 is extended. A second, smaller-diameter ring projection 13 is located concentrically with the projection 12. Both ring projections 12, 13 are connected to one another via radial ribs 11 formed from the cover base, so that
a kind of box girder is created, which creates an additional, circumferential stiffening of the lid base 3 and the inner edge 6 of the lid.
