Capsule for a substantially cylindrical vessel

Abstract

The present invention relates to a capsule for a substantially cylindrical vessel with a shell surface, an upper open end, and a lower closed end, wherein the shell surface, at least in the area of the open end, is of substantially cylindrical design. In order to protect substantially cylindrical vessels against breakage in cost-effective manner, it is suggested in the scope of the invention that the shell surface above the closed end comprises at least one means for forming a free space, which is a crimp, directed at least partially inwards on the shell surface. Here, the capsule is configured in such a way, that it can be fitted onto the bottom-side end of the substantially cylindrical vessel. The tolerance limits of the substantially cylindrical vessel are thereby compensated.

         8 . A capsule ( 1 ) for fitting onto the bottom-side end of a substantially cylindrical vessel ( 2 ), with a shell surface ( 1   a ), an upper open end ( 1   b ) and a lower closed end ( 1   c ), wherein the shell surface ( 1   a ), at least in the area of the open end ( 1   b ), is of substantially cylindrical design, wherein the shell surface ( 1   a ) and the lower closed end ( 1 ) comprise a plastic film, wherein the shell surface ( 1   a ), above the closed end ( 1   c ), comprises at least one means ( 3 ) for forming a free space ( 4 ), wherein the means ( 3 ) for forming a free space ( 4 ) protrudes into the inner area of the capsule ( 1 ), whereby a tapering of the internal cross-section of the capsule ( 1 ) is achieved, and wherein the means ( 3 ) for forming a free space ( 4 ) is formed as a crimp ( 3   c ) extending at least over a part of the circumference of the shell surface ( 1   a ) and directed inwards, against which the bottom of the substantially cylindrical vessel ( 2 ) abuts when fitting the capsule ( 1 ) and which prevents the substantially cylindrical vessel ( 2 ) from being inserted further into the capsule ( 1 ), wherein the shell surface ( 1   a ) comprises above the means ( 3 ) for forming a free space ( 4 ) at least one crimp ( 5 ), perpendicular to the axis of the capsule ( 1 ) and directed towards the interior of the capsule ( 1 ), and/or inwardly-directed nubs ( 6 ) and/or at least one crimp ( 7 ) parallel to the axis of the capsule ( 1 ) and directed towards the inside of the capsule ( 1 ), for compensating tolerances of the vessel diameter of the substantially cylindrical vessel ( 2 ). 
     
     
         9 . The capsule ( 1 ) according to  claim 8 , wherein the free space ( 4 ) is filled with a gas, in particular air, or a damping material. 
     
     
         10 . The capsule ( 1 ) according to  claim 8 , wherein the shell surface ( 1   a ) and the closed end ( 1   c ) are produced from polyvinyl chloride (PVC). 
     
     
         11 . The capsule ( 1 ) according to  claim 8 , wherein the capsule, in the area of the closed end ( 1   c ), comprises a perforation ( 8 ) for venting the interior area of the capsule ( 1 ). 
     
     
         12 . The capsule ( 1 ) according to  claim 8 , wherein the free space ( 4 ) is filled with a gas, in particular air, or a damping material. 
     
     
         13 . The capsule ( 1 ) according to  claim 12 , wherein the damping material comprise a material that is suitable to dampen mechanical movements, such as sponges, rubber or other resilient materials. 
     
     
         14 . A substantially cylindrical vessel ( 2 ) with an opening at the upper end ( 2   b ) and a bottom at the lower end ( 2   c ), with a capsule ( 1 ) according to  claim 8 , wherein the capsule ( 1 ) is fitted onto the lower end of the substantially cylindrical vessel ( 2 ). 
     
     
         15 . A substantially cylindrical vessel ( 2 ) with an opening at the upper end ( 2   b ) and a bottom at the lower end ( 2   c ), with a capsule ( 1 ) for a substantially cylindrical vessel ( 2 ) according to  claim 8 , wherein the substantially cylindrical vessel ( 2 ) is produced from glass or another material in which chemicals may be stored. 
     
     
         16 . The cylindrical vessel ( 2 ) with a capsule ( 1 ) according to  claim 15 , wherein the cylindrical vessel ( 2 ) is integrally formed.
