A roll-out cart includes a lid and a cart body supported on wheels. The cart body is comprised of a base wall, a front wall, a rear wall, and a pair of side walls that cooperate with each other to define a cart interior. The lid is attached to the cart body with a hinge connection and is moveable between an open position to provide access to the cart interior and a closed position to prevent access to the cart interior. A latch is pivotally mounted to the lid to lock the lid in the closed position.

The cart according to claim 1 wherein the latch includes a first retaining portion that cooperates with the cart to hold the lid in the closed position until an unlatching force is exerted on the latch and a second retaining portion that cooperates with the lid to hold the latch in an unlatched position until a re-latching force is exerted on the latch. 7. The cart according to claim 1 wherein the latch is pivotally connected to the lid at one end and extends to a pair of spaced apart retaining portions at an opposite end that snap-fit under the flange of the cart to latch the lid in the closed position. 8. The cart according to claim 7 wherein the latch includes a handle portion that connects the pair of spaced apart retaining portions, the handle portion being selectively actuatable to latch and unlatch the lid. 9. The cart according to claim 8 wherein the latch includes a pair of hinge member portions that extend inwardly toward each other, a pair of side arm portions that extend from the hinge member portions, and a pair of front arm portions that extend from the side arm portions to the retaining portions. 10. The cart according to claim 9 wherein the hinge member portions are mounted within holes formed within the lid. 11. The cart according to claim 9 wherein, when in a latched position, the side arm portions curve inwardly toward each other and extend forwardly toward a front of the cart, and the front arm portions extend forwardly and downwardly from the side arm portions to the retaining portions which extend inward and upward under the flange. 12. The cart according to claim 8 wherein the latch includes a connection portion that cooperates with the lid to firmly hold the latch in an unlatched position until a re-latching force is exerted on the latch. 13. The cart according to claim 12 wherein the connection portion comprises a pair of base portions that extend toward each other and a pair of inward arm portions that are pivotally secured to the lid, the base portions being non-collinear with the inward arm portions to create an offset between the inward arm portions and the base portions. 14. The cart according to claim 13 wherein the latch includes a pair of side arm portions that extend from the inward arm portions and a pair of front arm portions that extend from the side arm portions to the retaining portions, and including a pair of transition portions that extend between the inward arm portions and the base portions to create the offset. 15. The cart according to claim 13 wherein the lid includes at least one upwardly extending mounting boss for each inward arm portion. 16. The cart according to claim 15 wherein, as the inward arm portions pivot within the mounting bosses, the base portions react against an upper surface of the lid to generate a biasing force that holds the latch in the unlatched position. 17. The cart according to claim 13 wherein the lid includes a housing portion that extends upwardly from an upper surface of the lid and forms a corresponding recess underneath the lid, and wherein the inward arm portions extend into the recess. 18. The cart according to claim 17 wherein the latch includes a pair of transition portions that extend between the inward arm portions and the base portions to create the offset, and wherein, as the inward arm portions pivot with the lid, the base portions react against walls of the recess to generate a biasing force that holds the latch in the unlatched position. 19. The cart according to claim 1 wherein the cart body includes one or more supports extending rearwardly from the lip adjacent the rear wall and a pull handle that is secured to the supports, and wherein the lid includes arms located along a rear edge of the lid that hingeably secures the lid to the pull handle. 20. The cart according to claim 1 wherein the lid includes an upper flange that is spaced outwardly of a forward end of the lid, the upper flange comprising a handle to lift the lid. 21. A cart comprising: a base wall, front wall, rear wall, and a pair of side walls that cooperate with each other to define a cart interior;a lid moveable about a hinge connection between an open position to provide access to the cart interior and a closed position to prevent access to the cart interior; anda latch mounted to the lid to lock the lid in the closed position, wherein the latch is pivotally connected to the lid at one end and extends to a pair of spaced apart retaining portions at an opposite end that snap-fit under a flange of the cart to latch the lid in the closed position,wherein the latch includes a handle portion that connects the pair of spaced apart retaining portions, the handle being selectively actuatable to latch and unlatch the lid,wherein the latch includes a connection portion that cooperates with the lid to firmly hold the latch in an unlatched position until a re-latching force is exerted on the latch,wherein the connection portion comprises a pair of base portions that extend toward each other and a pair of inward arm portions that are pivotally secured to the lid, the base portions being non-collinear with the inward arm portions to create an offset between the inward arm portions and the base portions,wherein the latch includes a pair of side arm portions that extend from the inward arm portions and a pair of front arm portions that extend from the side arm portions to the retaining portions, and including a pair of transition portions that extend between the inward arm portions and the base portions to create the offset, andwherein the handle portion, the inward arm portions, and the base portions are generally parallel to each other. 22.
