The bulk bin sleeve pack includes a base that forms the bottom wall of the bulk bin. First and second wall members form the perimeter wall and are attached to one another and the base. The first and second wall members overlap a portion of the base. Locking tabs are associated with at least one of the base and the first and second wall members. Locking openings are associated with at least one of the base and the first and second wall members. The locking openings oppose the locking tabs when the first and second wall members are attached to the base to form the perimeter wall of the bulk bin. The locking tabs are lockingly inserted into the locking openings to secure the first and second wall members to the base to form the bulk bin. ## Claims ### Claim 1 A bulk bin sleeve pack for being repeatably erected to form a bulk bin having a bottom wall and a perimeter wall and collapsed when not in use, the bulk bin sleeve pack comprising: a base configured to form the bottom wall of the bulk bin; a first wall member configured to form a portion of the perimeter wall of the bulk bin, the first wall member having a bottom edge margin, a top edge margin, and first and second side margins, the bottom edge margin configured for attachment to the base so that the first wall member overlaps at least a portion of the base; a second wall member configured to form another portion of the perimeter wall of the bulk bin, the second wall member having a bottom edge margin, a top edge margin, and first and second side margins, the bottom edge margin of the second wall member being configured for attachment to the base so that the first side margin of the first wall member overlaps the second side margin of the second wall member, the second side margin of the first wall member overlaps the first side margin of the second wall member, and the second wall member overlaps at least a portion of the base; locking tabs associated with at least one of the base and the first and second wall members; locking openings associated with at least one of the base and the first and second wall members, the locking openings opposing the locking tabs when the first and second wall members are attached to the base to form the perimeter wall of the bulk bin; the locking tabs being configured to be lockingly inserted into the locking openings to secure the first and second wall members to the base to form the bulk bin. ### Claim 2 (depends on 1) The bulk bin sleeve pack as set forth in claim 1, wherein the locking tabs are configured to be repeatedly inserted into and withdrawn from the locking openings to erect and collapse the bulk bin. ### Claim 3 (depends on 1) The bulk bin sleeve pack as set forth in claim 1, wherein the first and second wall members include the locking openings and the base includes the locking tabs. ### Claim 4 (depends on 3) The bulk bin sleeve pack as set forth in claim 3, wherein the base includes a rim, the first and second wall members configured for attachment to the base so that the first and second wall members overlap the rim. ### Claim 5 (depends on 4) The bulk bin sleeve pack as set forth in claim 4, wherein the rim includes a plurality of sides, each side of the rim including at least one locking tab of the locking tabs. ### Claim 6 (depends on 5) The bulk bin sleeve pack as set forth in claim 5, wherein each of the locking tabs comprising a spine portion and a pair of wing portions connected to the spine portion at a free end thereof, the spine portion having a width less than a width of the locking openings and the locking tab at the free end having a width greater than the locking openings. ### Claim 7 (depends on 1) The bulk bin sleeve pack as set forth in claim 1, wherein the locking tabs are connected to the base for folding about a generally horizontal fold line. ### Claim 8 (depends on 1) The bulk bin sleeve pack as set forth in claim 1, wherein each of the locking tabs are hingedly connected to the respective base and/or first and second wall members. ### Claim 9 (depends on 8) The bulk bin sleeve pack as set forth in claim 8, each of the locking tabs is formed as one piece of material with the respective base and/or first and second wall members. ### Claim 10 (depends on 1) The bulk bin sleeve pack as set forth in claim 1, wherein the base, the first wall member and the second wall member are each formed from a single board. ### Claim 11 (depends on 10) The bulk bin sleeve pack as set forth in claim 10, wherein each of the boards comprises fluted plastic. ### Claim 12 (depends on 1) The bulk bin sleeve pack as set forth in claim 1, wherein each of the locking tabs comprising a spine portion and a pair of wing portions connected to the spine portion at a free end thereof, the spine portion having a width less than a width of the locking openings and the locking tab at the free end having a width greater than the locking openings. ### Claim 13 (depends on 1) The bulk bin sleeve pack as set forth in claim 1, wherein the first and second wall members are sized to be received in the base in a collapsed configuration of the bulk bin sleeve pack. ### Claim 14 A bulk bin comprising: a base having a perimeter; a perimeter wall extending circumferentially around a bulk bin interior and having a top edge margin and an opposite bottom edge margin arranged adjacent the perimeter of the base such that the base defines a bottom end of the bulk bin interior; and an interlocking connection securing the base and the perimeter wall together, the interlocking connection including at least one opening formed in either the base or the perimeter wall and at least one locking tab extending from the other of the base or the perimeter wall, the at least one locking tab extending through one of the at least one opening and locking the base and perimeter wall together. ### Claim 15 (depends on 14) The bulk bin as set forth in claim 14, wherein the at least one locking tab extends substantially perpendicular to the perimeter wall. ### Claim 16 (depends on 14) The bulk bin as set forth in claim 14, wherein the base includes the at least one locking tab and the perimeter wall includes the at least one opening, the at least one locking tab extending through one of the at least one opening and into the bulk bin interior to lock the base and perimeter wall together. ### Claim 17 (depends on 14) The bulk bin as set forth in claim 14, further comprising a locking tab of the at least one locking tab on each side of the base and an opening of the at least one opening on each side of the perimeter wall. ### Claim 18 (depends on 14) The bulk bin as set forth in claim 14, wherein the perimeter wall comprises a first wall member having a first side margin and a second side margin and a second wall member having a first side margin and a second side margin, the first side margin of the first wall member attached to the second side margin of the second wall member and the second side margin of the first wall member attached to the first side margin of the second wall member. ### Claim 19 A method of making a bulk bin sleeve pack comprising: forming from a blank a perimeter wall member having an opening adjacent to a bottom edge margin of the perimeter wall member; and forming from a blank a base having a perimeter, the base including a locking tab, the perimeter wall member being sized and shaped for attachment to the base to form a perimeter wall on the base so that the opening of the perimeter wall member is aligned with the locking tab of the base. ### Claim 20 (depends on 19) The method as set forth in claim 19, wherein forming the base comprises forming a rim and forming the locking tab from the rim.
