Supportable pressurizable container having a bottom for receiving a dip tube and base cup therefor

Abstract

A container having a curved bottom and base cup which allows the container to stand upright. The container and base cup are fitted together by a mechanical engagement having portions on the container and base cup. The mechanical engagement of the container is disposed within the bottom cone of the container. The mechanical engagement of the base cup is cantilevered from the bottom of the base cup. Such disposition reduces stress at the interface between the side wall of the container and edge of the base, providing for a smoother transition and better appearance. Also, this disposition provides resistance to separation of the container and base cup during drop impact. The bottom of the container may be curved and have a well therein for receiving the contents of the container and a dip tube.

1 . A container and a base cup attached thereto;
 the container having a curved bottom and side walls visible when the container is disposed on a horizontal surface, said container having side walls extending outwardly from said curved bottom and intercepting said curved bottom at a point of tangency;   the base cup fitting over at least a portion of said curved bottom of said container and having a bottom allowing said base cup and said container to sit upright on a horizontal surface, said base cup, having side walls extending outwardly from the bottom of said base cup and intercepting said side walls of said container at said plate of tangency;   a mechanical engagement which joins said base cup and said container and comprises complimentary engageable portions disposed on said container and on said base cup, a portion of said mechanical engagement be disposed on said bottom of said container, whereby said side walls of said container are free of said engagement when said base cup is attached thereto; and a well disposed in the bottom of said container for receiving contents of the container therein.   
   
   
       2 . A container and a base cup attached thereto according to  claim 1 , wherein said bottom of said container is hemispherically shaped. 
   
   
       3 . A container and a base cup attached thereto according to  claim 2 , wherein said container is pressurized and further comprising a dip tube for dispensing contents from said container, said dip tube having an end for receiving contents of said container, said end of said dip tube being disposed within said well of said container. 
   
   
       4 . A container and a base cup attached thereto according to  claim 1  wherein said well is congruent with said bottom of said container. 
   
   
       5 . A container and a base cup attached thereto according to  claim 4  wherein said bottom of said container is hemispherically shaped, and said well is round. 
   
   
       6 . A container and a base cup attached thereto according to  claim 5  wherein said container and base cup have a longitudinal axis therethrough, said well having a diameter and a longitudinal depth, said diameter being greater than said longitudinal depth. 
   
   
       7 . A container and a base cup attached thereto;
 the container being internally pressurized and having a curved bottom and side walls visible when the container is disposed on a horizontal surface, said container having side walls extending outwardly from said curved bottom and intercepting said curved bottom at a point of tangency;   the base cup fitting over at least a portion of said curved bottom of said container and having a bottom allowing said base cup and said container to sit upright on a horizontal surface, said base cup, having side walls extending outwardly from the bottom of said base cup and intercepting said side walls of said container at said plate of tangency;   a mechanical engagement which joins said base cup and said container and comprises complimentary engageable portions disposed on said container and on said base cup, a portion of said mechanical engagement be disposed on said bottom of said container, whereby said side walls of said container are free of said engagement when said base cup is attached thereto; and a well disposed in the bottom of said container for receiving contents of the container therein.   
   
   
       8 . A container and a base cup attached thereto according to  claim 7  pressurized to 80,000 to 120,000 ksm. 
   
   
       9 . A container and a base cup attached thereto according to  claim 8  pressurized to 90,000 to 110,000 ksm.
