Food and crayon snap-locking containers and adjustable shelving

Abstract

The inventions are a food and crayon snap locking container and adjustable shelving system for containers for use in bags. The food snap locking container invention allows for multiple containers to lock together so one hand can be used to move them. The crayon snap locking box invention allows for one hand to search for and remove a crayon without the box tipping over, and it allows for easy access to the favorite crayon. The adjustable shelving system allows for food containers of all sizes to be placed in a bag in an orderly manner that prevents leakage and fixes the containers in place.

1 . A storage system comprising:
 a plurality of storage containers, each storage container comprising:
 a container body, the container body comprising:
 at least one wall comprising a slot, the slot configured to receive a protrusion from another of the plurality of storage containers; 
 at least one wall comprising a protrusion, wherein the protrusion extends outward from an exterior surface of the at least one wall comprising a protrusion; and 
 
 a lid configured to engage a top surface of the container body; 
   wherein receipt of a protrusion of a first storage container by a slot of a second storage container at least partially prevents movement in at least one direction of the first storage container and the second storage container relative to one another.   
     
     
         2 . The storage system of  claim 1 , wherein each protrusion comprises one or more connecting arms and an outer plate, each connecting arm positioned generally perpendicular to a plane defined by the exterior surface of the at least one wall comprising a protrusion, wherein a proximal end of each connecting arm extends from the exterior surface of the at least one wall comprising a protrusion, and wherein the distal end of each connecting arm extends to the interior surface of the outer plate. 
     
     
         3 . The storage system of  claim 1 , wherein a cavity is defined by an interior surface of the protrusion and the exterior surface of the at least one wall comprising a protrusion, wherein the at least one wall comprising a slot further comprises at least one locking tab configured to extend into the cavity. 
     
     
         4 . The storage system of  claim 1 , wherein each of the plurality of storage containers comprises at least two protrusions and at least two slots. 
     
     
         5 . The storage system of  claim 1 , where the at least one wall comprising a protrusion further comprises at least one locking tab extending perpendicularly from the exterior surface of the at least one wall comprising a protrusion, wherein the at least one wall comprising a slot further comprises at least one locking tab receptacle configured to receive the at least on locking tab extending perpendicularly from the exterior surface of the at least one wall comprising a protrusion. 
     
     
         6 . The storage system of  claim 5 , wherein the receipt of the at least one locking tab of the first container by the locking tab receptacle of the second container at least partially prevents movement in at least one direction different from the at least one direction at which movement is partially prevented by the receipt of the protrusion of the first storage container by the slot of the second storage container. 
     
     
         7 . The storage system of  claim 1 , wherein the at least one wall comprising a slot comprises a plurality of slots and the at least one wall comprising a protrusion comprises a plurality of protrusions. 
     
     
         8 . The storage system of  claim 1 , wherein each storage container is configured to engage four other storage containers. 
     
     
         9 . The storage system of  claim 2 , wherein the outer plate extends at an angle from the one or more connecting arms such that the outer plate is not parallel to the exterior surface of the at least one wall comprising a protrusion. 
     
     
         10 . A storage container comprising:
 a container body comprising a plurality of walls, wherein a protrusion extends from at least one wall; and   a removable lid comprising a slot configured to engage with the protrusion, wherein upon engagement of the slot with the protrusion, movement of the lid and storage container relative to one another is at least partially prevented in at least one direction.   
     
     
         11 . The storage container of  claim 10 , wherein the protrusion is t-shaped. 
     
     
         12 . The storage container of  claim 10 , wherein the lid comprises a connection surface configured to detachably engage a top surface of the container body by a press fit. 
     
     
         13 . The storage container of  claim 10 , wherein an exterior surface of the lid comprises a recessed portion for storage of one or more items. 
     
     
         14 . The storage container of  claim 13 , wherein the recessed portion is configured to removably secure one or more writing instruments. 
     
     
         15 . The storage container of  claim 10 , wherein when the slot is engaged to the protrusion, a long axis of the lid is positioned generally perpendicular to a long axis of the container body. 
     
     
         16 . The storage container of  claim 15 , wherein the lid is sized to prevent tipping of the container body when the slot is engaged to the protrusion and the container body is positioned on a flat surface. 
     
     
         17 . The storage container of  claim 10 , wherein the container body comprises a stop configured to prevent movement of the lid in at least one direction along a length of the protrusion, the stop being wider than an opening of the slot in at least one dimension.
