The invention relates to a keg for storage where it is expediently made of a plastic and the transport of pressurized fluid material of essentially the same wall thickness, in particular beer, which are formed from one and which are also produced in plant with plastic The container and thus the cap surfaces fixed to the spherical container are adapted in their shape to the surface of the container, 5 spherical shape of the container,

Such barrels 15 The spherical shape of the central pressure order in a certain way a compromise between holder is known to be the ideal configuration for the endeavor to give a barrel the desired external pressure vessel. It has therefore been in the form of a conventional wooden barrel, and for a long time it has represented the desire for the construction of containers to hold as large a volume as possible, especially for pressurized liquids or gases. However, such containers usually consist of creating liquids. In addition to one made of steel or suitable metal alloys. In the one-piece injection-molded Kunststoffaß, plastic construction, especially in the construction of Kunststoffein Kunststoffein, has become known, in which for beer kegs, the pure spherical shape for the actual reinforcement of the actual container in its shape has not been used until now, however, since it was adapted to the surface of the container Plastic 25 this form of the conventional barrel form ziemarmierungen for the formation of rolling, supporting and borrowed differs widely and only through the caps a stacking rings are provided. These rings are used to create a container that actually comes very close to the conventional one at the same time as reinforcements for the relatively thin barrel shape. In addition, walled containers and serve to allow the volume formed on the caps or within the prescribed tolerances to keep the special rolling rings that can be inserted into the caps, ie an undesirable bulging, which and that also formed on the caps due to the internal pressure could be caused to prevent stacking rings, each one directed radially inward.

The first-mentioned barrel has, presumably conditionally, written below on the basis of the drawings due to its unusual at least for a beer barrel. In the drawing shows

If you put the caps and the central container out of the specially designed for this purpose suitable low-pressure polyethylene, this material combines very quickly and tightly with the from the same material existing pipes of the cavities 5. ίο

As one can see from FIG. 1 recognizes, the inner surfaces 6 coming to rest on the container 1 are the two caps 2 of the spherical shape of the container 1 adapted. This gives you the option of both parts in a simple manner to the one shown in FIG. 3 to connect the unit. There are central containers 1 and Caps 2 made of the same plastic, for example polyethylene, so you can use the prefabricated central container and weld caps under the action of heat.

In the F i g. 4 to 7 a second embodiment of the barrel is shown in which the caps 12 completely encompass the spherical container 10. The caps 12 are made of a plastic material formed by essentially the same wall thickness, with also the one in attachment with the spherical container 10 located cap surfaces 11 and 16 are adapted to the spherical shape of the container.

As one can see particularly well from FIG. 6 recognizes, the spherical container 10 is also made up of two spherical shell halves 10 a and 106 formed along their edge in the in F i g. 7 through a kind of tongue and groove connection 21 are connected to one another and thermally welded or glued. In this embodiment, the rolling rings 13 are not formed in one piece with the caps 12, but rather are only inserted into the grooves provided after the caps have been manufactured. Even with this one The embodiment has the spherical container, as can be seen from FIG. 4 recognizes two openings 14 for the inlet or dispensing of the pressurized liquid to be absorbed by the container 10. In order to save weight and in addition to simplify handling of the barrel according to FIGS. 4 to 7 the same is provided with elongated recesses 15. In a similar way to the one related with the F i g. 1 to 3 described first embodiment, the stacking rings 17 of the two Caps 12 each have an inwardly directed flange 9, which also serves to facilitate the handling of the Barrel to facilitate. The shape of the caps in this embodiment requires one steeper wall part 18 following the stacking ring 17, a flatter wall part 19, which extends into the area of the rolling ring 13, and finally a cylindrical area 20, which in the cylindrical region 20 of the second cap 12, the edges of the two caps 12 in in the same way as the edges of the two hollow hemispherical shells by a kind of tongue and groove connection according to FIG. 7 are connected to each other.
