Cylindrical vessel with a base ring and with a coupling device

In this cylindrical vessel with a base ring and with a coupling device, the base ring has two guide segments located opposite one another. On the head of the vessel there are supports which carry two ring segments arranged opposite one another. When two vessels are coupled to one another, the ring segments engage behind the guide segments to make a bayonet connection.

The invention relates to a cylindrical vessel with a base ring and with a 
coupling device which makes it possible to connect such vessels to one 
another. 
To avoid the need to cover unnecessary distances to obtain additional 
stores, it is expedient, for example in the maintenance of refrigerating 
plants, to have many different refrigerating agents on hand at all times. 
The object is, therefore, to provide a vessel, especially for gases and/or 
liquids, which can be ganged to identical vessels, e.g., by suspending one 
from another or mounting one atop another, to form interconnected units. 
The object is achieved by means of a cylindrical vessel with a base ring 
and with a bayonet coupling device, wherein 
(a) the base ring has two guide segments located opposite one another, and 
(b) there are on the head of the vessel supports which carry two ring 
segments arranged opposite one another. 
The guide segments can be made self-locking and can be inclined up to 
3.degree. relative to the normal of the vessel axis. 
The advantages achieved as a result of the invention are to be seen 
basically in that by means of the coupling device cylindrical vessels can 
be coupled rigidly to form relatively large units and can consequently 
also be stacked advantageously. Several vessels can be carried at the same 
time. For transport, the vessels can be fastened simply and effectively to 
the transport vehicle, provided that, for example, the base ring is 
mounted on the transport bed by means of the segments located opposite one 
another.

The cylindrical vessel 1 is provided with a base ring 2 which has two guide 
segments 3 located opposite one another. The guide segments 3 can be made 
self-locking, for example they can be gummed or surface-treated in another 
way. Furthermore, they can be inclined up to 3.degree. relative to the 
normal of the vessel axis. Supports 4 are located opposite the base ring 
2, that is to say consequently on the head of the vessel 1, so that they 
can carry two ring segments 5 located opposite one another. When two 
vessels are coupled to one another, the ring segments 5 engage behind the 
guide segments 3, as a result of which the rigid connection between the 
vessels is made. 6 denotes orifices in the base ring and 7 denotes the 
filling connection of the vessel.
