Utility assembly and coupling mechanism

A container assembly comprising:

• a first container comprising:
• a lid comprising a top surface of the first container, the lid pivotally attached to the first container;
• a front face;
• a handle coupled to the front face;
• a plurality of female couplers located on the lid of the first container, each of the plurality of female couplers comprising:
• a depressed surface recessed below the top surface;
• a rear wall extending upward from a rear portion of the depressed surface;
• a front wall extending upward from a front portion of the depressed surface;
• two opposing sidewalls each extending between the front wall and the rear wall and extending upward along opposing side portions of the depressed surface, wherein the rear wall and the front wall both extend between the two opposing sidewalls;
• and
• a rib extending from the rear wall in a first direction toward the front face, the rib located above the depressed surface and between the two opposing sidewalls;
• wherein one of the plurality of female couplers is located behind one of the other female couplers relative to the front face of the first container;
• a latch recess located on the lid of the first container, the latch recess comprising:
• a bottom wall recessed below the top surface;
• a front wall extending upward from the bottom wall;
• and
• a rear wall extending upward from the bottom wall;
• and
• a second container comprising:
• a front face;
• a bottom surface;
• a plurality of male couplers extending from the bottom surface of the second container, each of the plurality of male couplers comprising a tongue that is offset from the bottom surface and extends in a second direction away from the front face of the second container, the tongue of each of the plurality of male couplers of the second container is engageable below one of the ribs of the female couplers of the first container when the second container is stacked on top of the first container;
• and
• a latch positionable into a locked position in which a lower portion of the latch protrudes downward relative to the bottom surface of the second container and is received in the latch recess such that the latch prevents sliding displacement of the second container relative to the first container, preventing disengagement of the tongues of the male couplers of the second container from the ribs of the female couplers of the first container when the second container is stacked on top of the first container.
