Pressure container

Abstract

A pressure container has inner and outer containers ( 10; 20 ) having, respectively, first and second chambers ( 11; 21 ) for receiving, respectively, first and second media ( 21, 22 ) and sealed with respect to each other, a cover ( 25 ) for closing both the inner container ( 10 ) and the outer container ( 20 ), a valve ( 40 ) provided in the cover ( 25 ) for delivering one of the first and second media from a respective one of the first and second chambers, and a protective jacket ( 30 ) for enclosing the outer container ( 20 ) and having a bottom ( 36 ) building toward a bottom ( 26 ) of the outer container ( 20 ) provided at an end of the outer container ( 20 ) remote from the valve ( 40 ), with the protective jacket ( 30 ) further having, at its end remote from its bottom, a crimp rim ( 34 ) engageable with a crimp ( 34 ) of the cover ( 25 ) for supporting the cover ( 25 ).

1 . A pressure container, comprising an inner container ( 10 ) having a first chamber ( 11 ) for receiving a first medium ( 12 ); an outer container ( 20 ) having a second chamber ( 21 ) for receiving a second medium ( 22 ) and sealed with respect to the first chamber ( 11 ) of the inner container ( 20 ); a cover ( 25 ) for closing both the inner container ( 10 ) and the outer container ( 20 ); a valve ( 40 ) provided in the cover ( 25 ) for delivering one of the first medium and the second medium from a respective one of the first chamber and the second chamber outwardly; and a protective jacket ( 30 ) for enclosing the outer container ( 20 ) and having a bottom ( 36 ) bulging toward a bottom ( 26 ) of the outer container ( 20 ) provided at an end of the outer container ( 20 ) remote from the valve ( 40 ), the protective jacket ( 30 ) further having, at an end thereof remote from the bottom thereof, a crimp rim ( 34 ) engageable with a crimp ( 24 ) of the cover ( 25 ) for supporting the cover ( 25 ).  
   
   
       2 . A pressure container according to  claim 1 , wherein the second chamber ( 21 ) of the outer container ( 20 ) is formed as a propellant chamber, with the second medium ( 22 ) being propellant.  
   
   
       3 . A pressure container according to  claim 1 , wherein an inlet opening ( 27 ) is formed in the bottom ( 26 ) of the outer container ( 20 ) for filling the outer container ( 20 ), and wherein the pressure container further includes means ( 29 ) for closing the inlet opening ( 27 ).  
   
   
       4 . A pressure container according to  claim 3 , wherein the bottom ( 36 ) of the protective jacket ( 30 ) supports the closing means ( 29 ) at a lower end of the closing means.  
   
   
       5 . A pressure container according to  claim 4 , wherein the bottom ( 36 ) of the protective jacket ( 30 ) has an opening ( 37 ) that insures access to the closing means ( 29 ) from outside.
