Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
217 words
An article retainer for stacked assembly with a plurality of identical other article retainers, said article retainer comprising: a bottom and an upstanding rear wall which extends up from said bottom; a first socket rigidly attached to said rear wall at one end of the latter, said first socket extending vertically for substantially less than full height of said rear wall and terminating at its lower end in a downwardly-facing shoulder which is spaced a predetermined distance above said bottom; a second socket rigidly attached to said rear wall at the opposite end of the latter, said second socket extending vertically for substantially less than the full height of said rear wall and terminating at its upper end in an upwardly-facing shoulder which is spaced above said bottom by substantially said predetermined distance; one of said sockets having a vertical recess therein which is open at said shoulder on said one socket; and a post rigidly attached to the other of said sockets and projecting vertically beyond the respective shoulder thereon, said post being shaped and dimensioned to be slidably insertable into said recess in said one socket on an adjoining identical article carrier to releasably interlock the two article carriers at the same level with their respective downwardly and upwardly-facing shoulders substantially contiguous to each other.
