Abstract
A three-level stacking container adapted to stack within a lower container of like construction in a low-level stack position or an intermediate-stack position, or stack on said lower container in a high-stack position, depending upon the orientation of said upper container with respect to said lower container. Opposing first and second wall structures of said container comprise bar members which extend in an upwardly direction between a lower border flange and an upper rim. Said bar members are arranged such that the bar members of an upper container parallel the bar members of a lower container when said upper container is stacked within said lower container.
Claims27
A generally rectangular container adapted for stacking with another like container at three different levels comprising a generally horizontally disposed bottom, and first and second opposed sidewalls projecting upwardly from the opposing first and second sides of said bottom, respectively, with each of said first and second sidewalls comprising:
- a border flange extending along the respective first or second opposite side of the bottom and being vertically disposed in a first vertical plane adjoining said respective side of said bottom,
- an upper rim being vertically disposed above and in a second vertical plane outside and parallel to that of said first vertical plane,
- a plurality of bar members extending vertically in a third vertical plane in an upwardly direction between the outer surface of said border flange and the inner surface of said upper rim, said bar members in one of said first and second opposed sidewalls being arranged with respect to the bar members and spacing thereof in the opposite of said first and second sidewalls so that another like container, when reversely oriented with respect to said container, will stack inside said container in a low stack position,
- a plurality of spaced-apart stacking feet on the outer surface of the bottom flange,
- a plurality of stacking saddles on the inner surface of said rim spaced above said stacking feet for registering in vertical alignment with said plurality of stacking feet of a like container placed upon said container in a like orientation so that the upper like oriented like container will stack inside said container in an intermediate stack position, said stacking feet and said stacking saddles being of such dimensions and so positioned as not to prohibit a like container from being placed in said container in said low stack position, and
- a pivotable bar means extending along and mounted to said rim, said bar means being capable of resting upon at least some of said stacking saddles inside said rim and being of such dimensions that when said bar means so rests upon said stacking saddles, another like oriented or reversely oriented like container will stack upon said bar means of said container in a high stack position, said bar means further being capable of being pivoted to a point which will allow a like container to be stacked in said container in either low stack or intermediate stack position.
A generally rectangular container adapted for stacking with another like container at three different levels comprisng a generally horizontally disposed bottom, and first and second opposed sidewalls projecting upwardly from the opposing first and second sides of said bottom, respectively, with each of said first and second sidewalls comprising:
- a border flange extending along the respective first or second opposite side of the bottom and being vertically disposed in a first vertical plane adjoining said respective side of said bottom,
- an upper rim being vertically disposed above and in a second vertical plane outside and parallel to that of said first vertical plane,
- a plurality of bar members extending in a third vertical plane in an upwardly direction between the outer surface of said border flange and the inner surface of said upper rim, said bar members in one of said first and second opposed sidewalls being arranged with respect to the bar members and the spacing thereof in the opposite of said first and second sidewalls so that another like container when like oriented will stack inside said container in a low stack position,
- a plurality of spaced-apart stacking feet on the outer surface of the bottom flange,
- a plurality of stacking saddles on the inner surface of said rim spaced above said stacking feet for registering in vertical alignment with said plurality of stacking feet of a like container placed upon said container in a reverse orientation so that the upper reversely oriented like container will stack inside said container in an intermediate stack position, said stacking feet and said stacking saddles being of such dimensions and so positioned as not to prohibit a like container from being placed in said container in said low stack position, and
- a pivotable bar means extending along and mounted to said rim, said bar means being capable of resting upon at least some of said stacking saddles inside said rim and being of such dimensions that when said bar means so rests upon said stacking saddles, another like oriented or reversely oriented like container will stack upon said bar means of said container in a high stack position, said bar means further being capable of being pivoted to a point which will allow a like container to be stacked in said container in either low stack or intermediate stack position.
A generally rectangular container adapted for stacking with another like container at three different levels comprisng a generally horizontally disposed bottom, and first and second opposed sidewalls projecting upwardly from the opposing first and second sides of said bottom, respectively, with each of said first and second sidewalls comprising:
- a border flange extending along the respective first or second opposite side of the bottom and being vertically disposed in a first vertical plane adjoining said respective side of said bottom,
- an upper rim being vertically disposed above and in a second vertical plane outside and parallel to that of said first vertical plane,
- a plurality of bar members extending upwardly in a third vertical plane between the outer surface of said border flange and the inner surface of said upper rim, said bar members in one of said first and second opposed sidewalls being arranged with respect to the bar members and spacing thereof in the opposite of said first and second sidewalls so that another like container will stack inside said container in a low stack position either when like oriented or when reversely oriented,
- a plurality of spaced-apart stacking feet on the outer surface of the bottom flange,
- a plurality of stacking saddles on the inner surface of said rim spaced above said stacking feet, said stacking feet and said stacking saddles being of such dimensions and so positioned as not to prohibit a like container from being placed in said container in a low stack position and so as to allow a like container to stack in an intermediate stack position wherein the stacking feet of the like container register in vertical alignment with the stacking saddles of said container when said like container is placed upon said container in an orientation reverse to that which allows said like container to stack in said container in the low stack position,
- a pivotable bar means extending along and mounted to said rim, said bar means being capable of resting upon at least some of said stacking saddles inside said rim and being of such dimensions that when said bar means so rests upon said stacking saddles, another like oriented or reversely oriented like container will stack upon said bar means of said container in a high stack position, said bar means further being capable of being pivoted to a point which will allow a like container to be stacked in said container in either low stack or intermediate stack position.
