Back bumper for can rack systems

A can rack system comprising:

• a plurality of back bumpers, each back bumper of the plurality of back bumpers comprising:
• a first flap, the first flap configured to flex, from a first position, downward to a second position in response to pressure exerted by a can descending through a compartment of the can rack system while the can is in contact with the first flap, and the first flap configured to flex upward from the second position to first position when the can descending through the compartment is below and no longer in contact with the first flap;
• a second flap positioned substantially perpendicular to the first position of the first flap;
• a raised step positioned between the second flap and the first flap, the raised step configured to enable the first flap to move independently of the second flap;
• and
• a flange protruding from the second flap, the flange and the second flap configured to removably couple the back bumper to the can rack system by hooking on to a back wall of the can rack system such that the second flap is positioned on an inner side of the back wall and the flange is positioned on an outer side of the back wall.

A method comprising:

• installing a plurality of back bumpers in a can rack system by:
• inserting, for each back bumper of the plurality of bumpers, a flange through a slot in a back wall of the can rack system, the flange protruding from a second flap:
• hooking, for each back bumper of the plurality of bumpers, the flange and the second flap onto the back wall by positioning the second flap on an inner side of the back wall and by positioning the flange on an outer side of the back wall;
• and
• positioning, for each back bumper of the plurality of bumpers, a first flap in a compartment of the can rack system to cause the first flap to contact each can of a plurality of cans descending through the compartment of the can rack system, the first flap configured to flex, from a first position, downward to a second position in response to pressure exerted by the can descending through the compartment while the can is in contact with the first flap, and the first flap configured to flex upward from the second position to first position when the can descending through the compartment is below and no longer in contact with the first flap.
