Claim:
A container comprising: a first portion having a first volume formed by a bottom surface, a first and second sidewall, and an end wall; a second portion having a second volume formed by a bottom surface, a first and second sidewall, and an end wall, the second volume of the second portion overlapping the first volume of the first portion, and the second portion being slidably coupled with the first portion such that the first portion and the second portion are selectively adjustable between a retracted position and an extended position; a retention portion disposed on the first sidewall of the first portion; and a receiving portion disposed on the second sidewall of the first portion, the receiving portion on the second sidewall of the first portion being structured differently than the retention portion on the first sidewall of the first portion, the receiving portion being configured to selectively engage with a retention portion of an adjacent container placed next to the container defined by the first portion and the second portion, the retention portion of the adjacent container being substantially identically structured as the retention portion of the container defined by the first portion and the second portion, and the retention portion of the container being configured to selectively engage with a receiving portion of another adjacent container placed next to the container defined by the first portion and the second portion, the receiving portion of the another adjacent container being substantially identically structured as the receiving portion of the container defined by the first portion and the second portion.
