Abstract
Abstract A rectangular or square stackable plastic carrier, more particularly a plastic crate, comprises a support bottom part 1 formed of a bottom 2 with an upright edge 3 at its periphery. Corner columns 4 are able to fit at their top end and bottom end respectively, into the bottom and top side of a carrier disposed thereon and therebeneath. The length H of the corner columns is a multiple of the height h of the bottom part 1. The external distance L 1 between two opposite set-back sides 5 of the bottom part 1 is substantially equal to or less than the internal distance L 2 between two corner columns measured between the same opposite set-back sides 5, said set-back sides being provided with a handle 6. The set-back part 5 corresponds to the transverse dimension of a corner column. In the space between two corner columns 4 and the set-back part 5 free ends of corner columns of a carrier being therebeneath in a staggered relationship, may be received. The short side of the carrier or crate is preferably at least (the multiple/2+1) times the column width B and the long side is preferably at least equal to the width of the crate+(the multiple/2-1) times the column width B. The construction of the carriers allows an easy stacking or nesting of carriers in a staggered position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
151 words
A plurality of rectangular trays for alternate transverse stacking one upon another each tray comprising (a) a rectangular bottom having upstanding side and end walls of the same vertical height, (b) four flat walled rectangular posts upstanding in pairs from each end of said end walls, (c) the height of said posts being of a multiple of the height of said side and end walls of a tray, (d) a flat walled handle extending from the outside of each end wall and lying intermediate said flat walled rectangular posts, and (e) the space between said flat walled handle and said rectangular posts defining a cutout to provide a sliding interlock between a flat wall of said handle and one wall of said flat walled corner posts to assure an interlocked vertical nested alternately transversely disposed stack of trays for transport facilitating quick and easy removal of the trays from the stack.
Claim 2
Dependent Claim
151 words
A plurality of rectangular trays for alternate transverse stacking one upon another each tray comprising (a) a rectangular bottom having upstanding side and end walls of the same vertical height, (b) four flat walled rectangular posts upstanding in pairs from each end of said end walls, (c) the height of said posts being of a multiple of the height of said side and end walls of a tray, (d) a flat walled handle extending from the outside of each end wall and lying intermediate said flat walled rectangular posts, and (e) the space between said flat walled handle and said rectangular posts defining a cutout to provide a sliding interlock between a flat wall of said handle and one wall of said flat walled corner posts to assure an interlocked vertical nested alternately transversely disposed stack of trays for transport facilitating quick and easy removal of the trays from the stack.
Claim 3
Dependent Claim
43 words
Stackable carrier according to claim 1, wherein the external distance between two opposite sides of the bottom part adjacent the rectangular corner post, is practically equal to or less than the internal distance between two corner posts measured between the same opposite sides.
Claim 4
Dependent Claim
71 words
Stackable plastic carrier for goods or articles, more particularly a plastic crate as claimed in claim 1, wherein said support bottom part provided near the corner of the post, the said and end walls of said support bottom part being provided with a cutout at least at two opposite sides near each post, each set-back part corresponding at least to the transverse dimensions of a corner column situated at that point.
Claim 5
Dependent Claim
26 words
Stackable carrier according to claim 3, wherein the cutout part at each opposite side of one post extends continuously from one post to the other post.
Claim 6
Dependent Claim
84 words
Stackable plastic carrier for goods or articles, more particularly a plastic crate as claimed in claim 1, wherein said support bottom part has upright post at the corners thereof, which upright post and support bottom part are made as a single plastic moulding, the columns on opposite sides being so disposed externally against the support bottom part that here is space available adjacent the columns at these opposite sides to receive free column ends of a carrier or crate disposed therebeneath in staggered relationship.
Claim 7
Dependent Claim
34 words
Stackable carrier according to claim 1, wherein the post are provided, at their bottoms, with connecting members which can engage around the top ends of post of a similar carrier or crate disposed therebeneath.
Claim 8
Dependent Claim
33 words
Stackable carrier according to claim 1, the post having a rectangular transverse periphery, their maximum transverse dimension being parallel to those sides of the support bottom part where the cutout parts are disposed.
Claim 9
Dependent Claim
90 words
Stackable carrier according to claim 1, wherein the carrier comprises at least one of the following features: the base of the bottom part has a rectangular pattern and the short side is at least (the multiple/2+1) times the column width; the base of the bottom part has a rectangular pattern and the long side is at least equal to the width of the carrier or crate+(the multiple/2-1) times the column width; the support bottom part is provided with an upright edge(s), said upright edge(s) being provided with correspondingly set-back parts.
Claim 10
Dependent Claim
29 words
Stackable carrier according to claim 3, wherein the base of the bottom part is practically square and the cutout parts are disposed on all four sides of the bottom.
