Container stacking system with universal members
Universal members placed between containers having different stacking patterns permit stacking of these containers regardless of the type of container positioned as the bottom container. The universal members include an appropriate thickness and a plurality of openings configured to receive the different stacking patterns. Depending on the containers being stacked, the universal members may take different forms. For example, one universal member may include T-shaped openings while another universal member may include rectangular-shaped openings with offset members.
1. A container stacking system for stacking containers, the container stacking system comprising:
a first stackable container having a first stacking pattern including a first upper plurality of protrusions secured to and extending from an upward facing surface of the first stackable container and a first lower plurality of protrusions secured to and extending from a downward facing surface of the first stackable container;
a second stackable container having a second stacking pattern including a second upper plurality of protrusions secured to and extending from an upward facing surface of the second stackable container and a second lower plurality of protrusions secured to and extending from a downward facing surface of the second stackable container;
a third stackable container having a third stacking pattern extending from both an upward facing surface and a downward facing surface of the third stackable container;
a first universal member located between the first and second stackable containers when the first and second stackable containers are in a stacked configuration, the first universal member having a first arrangement of openings on a first side and a second side of the first universal member configured to receive at least a portion of the first lower plurality of protrusions on the first side and at least a portion of the second upper plurality of protrusions on the second side, the first lower plurality of protrusions have a first depth and a first lateral pattern, the second upper plurality of protrusions have a second lateral pattern different than the first lateral pattern, and the thickness of the first universal member is greater than a combined height of the first lower plurality of protrusions and the second upper plurality of protrusions; and
a second universal member located between the second and third stackable containers when the second and third stackable containers are in a stacked configuration, the second universal member having a second arrangement of openings configured to receive at least a portion of the second stacking pattern and at least a portion of the third stacking pattern.
2. The container stacking system of claim 1 , wherein the first stacking pattern includes at least two T-shaped protuberances.
3. The container stacking system of claim 1 , wherein the second stacking pattern includes at least two T-shaped protuberances.
4. The container stacking system of claim 1 , wherein the first stacking pattern includes a first plurality of rectangular-shaped protuberances located adjacent to a second plurality of rectangular-shaped protuberances.
5. The container stacking system of claim 1 , wherein the second stacking pattern includes a first plurality of rectangular-shaped protuberances located adjacent to a second plurality of rectangular-shaped protuberances.
6. The container stacking system of claim 1 , wherein the first arrangement of openings define a perimeter shape sized to receive both the first lower plurality of protrusions and the second upper plurality of protrusions.
