Telescopically Stackable Container

Abstract

The container includes a superiorly opened tubular body formed by a peripheral side wall which affixes a bottom wall and which presents at least two inverted frusto-conical portions defining respective circumferential reductions in the contour of the tubular body, so that, upon fitting one container inside the other, the lower end edge of the peripheral side wall of the upper container is seated on the lower frusto-conical portion of the lower container; the lower frusto-conical portion of the upper container is seated on another frusto-conical portion of the lower container; and the upper frusto-conical portion of the upper container is seated on the upper end edge of the lower container.

1 . A telescopically stackable container, of the type which comprises a tubular body formed by a peripheral side wall which presents a lower end edge affixing a bottom wall, and an upper end edge surrounding an opening (A) and which is conformed to receive and retain an upper wall generally in the form of a lid, said container being characterized in that the peripheral side wall presents, axially spaced apart, at least two inverted frusto-conical portions with short height, defining respective progressive downwardly descending circumferential reductions in the contour of the tubular body, which are dimensioned and positioned so that, upon fitting a tubular body inside the other:
 the lower end edge of the peripheral side wall of the upper the tubular body is seated on a lower frusto-conical portion of the lower tubular body; the lower frusto-conical portion of the upper tubular body is seated on another frusto-conical portion of the lower tubular body, different from the lower frusto-conical portion of the latter; and—an upper frusto-conical portion of the upper tubular body is seated on the upper end edge of the lower tubular body.   
     
     
         2 . The container, as set forth in  claim 1 , characterized in that the lower frusto-conical portion of the upper tubular body is seated on an upper frusto-conical portion of the lower tubular body. 
     
     
         3 . The container, as set forth in  claim 1 , characterized in that the peripheral side wall further presents at least one inverted median frusto-conical portion of short height, axially spaced from the lower frusto-conical portion and the upper frusto-conical portion, defining a respective circumferential reduction in the contour of the tubular body, which median frusto-conical portion is dimensioned and positioned so that, upon fitting one tubular body inside the other:
 the lower frusto-conical portion of the upper tubular body is seated on the median frusto-conical portion of the lower tubular body; and   the median frusto-conical portion of the upper tubular body is seated on the upper frusto-conical portion of the lower tubular body.   
     
     
         4 . The container, as set forth in  claim 1 , characterized in that the peripheral side wall presents a tubular portion defined between each two consecutive frusto-conical portions and between each of the lower frusto-conical portion and upper frusto-conical portion and the adjacent lower end edge and upper end edge. 
     
     
         5 . The container, as set forth in  claim 4 , characterized in that the tubular portions of the peripheral side wall presents a constant cross-section throughout the height thereof. 
     
     
         6 . The container, as set forth in  claim 4 , characterized in that the tubular portions of the peripheral side wall present the same height. 
     
     
         7 . The container, as set forth in  claim 1 , characterized in that each of the frusto-conical portions has its inclined wall portion presenting an angle not superior to 45° in relation to the plane which contains the axis of the container. 
     
     
         8 . The container, as set forth in  claim 1 , characterized in that the frusto-conical portions present the same height and the same radial width (R).
