Abstract: A container comprising walls. A first wall has a latch connected thereto by a flexible arm at a first lateral end. The latch comprises i) a latch body connected to the flexible arm and resiliently, outwardly movable, the latch body having an interior surface sloped to partially face a second lateral end of the first wall, and ii) a stop contact having a contact surface resiliently movable relative to the latch body. The stop contact is connected to the latch body at a location outward of where a stop contacts the contact surface. A second wall comprising a stop is located at the first lateral end, and is movable on a hinge. The stop is aligned to contact the contact surface as the second wall is rotated from an erected arrangement and to contact the interior surface as the second wall is rotated from the collapsed arrangement.

Abstract: A container having walls, one having a projection including a hook and an exterior surface opposite the hook having an external contact location, the hook extending away from the contact surface, the contact location disposed interiorly of the hook. The container includes a door, and a latch coupled to the door by a spring. The latch comprises a catch and a binding arm, and has a contact surface positioned to fit the projection between the catch and contact surface. The latch has a locked position in which the catch and hook maintain the door in the closed position, and an unlocked position in which the door is movable. The spring biases the latch into the locked position. Sufficient pressure on the latch overcomes the biasing to achieve the unlocked position, to allow the open position to be attained. When in the locked position, the contact surface faces the contact location.
