Abstract

A cardboard package has a cardboard container and a cardboard tray. The cardboard container has a proximal end, a distal end, and a first wall extending between the proximal and distal ends, the cardboard container further having a first recess in the first wall, the cardboard container further having a first protrusion on the first wall, the first protrusion extending inwardly from the first wall, the first protrusion positioned proximal of the first recess. The cardboard tray has a first wall and a first resilient member, the first resilient member being a tab, the tab having at least one of a shape or a position selected such that the tab cannot extend into the first recess when the package is in a closed position, the tab further shaped and positioned to engage the first protrusion in the cardboard container, whereby the cardboard tray is maintained in the closed position.

What is claimed is: 
     
         1 . A cardboard package, comprising:
 a cardboard container, the cardboard container having a proximal end, a distal end, and a first wall extending between the proximal and distal ends, the cardboard container further having a first recess in the first wall, the cardboard container further having a first protrusion on the first wall, the first protrusion extending inwardly from the first wall, the first protrusion positioned proximal of the first recess; and   a cardboard tray, the cardboard tray having a first wall and a first resilient member, the first resilient member being a tab, the tab having at least one of a shape or a position selected such that the tab cannot extend into the first recess when the package is in a closed position, the tab further shaped and positioned to engage the first protrusion in the cardboard container, whereby the cardboard tray is maintained in the closed position.   
     
     
         2 . The package of  claim 1 , wherein:
 the first resilient member is disengageable from the first protrusion in response to an inward force applied to the first resilient member through the first recess.   
     
     
         3 . The package of  claim 1 , wherein:
 the first resilient member is shaped and positioned to engage an interior surface of the first wall and the first protrusion, whereby the cardboard tray is maintained in the closed position.   
     
     
         4 . The package of  claim 1 , wherein:
 folding the second cardboard sheet comprises forming the first resilient member and a second resilient member, the second resilient member being a second tab.   
     
     
         5 . The package of  claim 1 , wherein:
 the cardboard container further comprises a track; and   the cardboard tray further comprises a second tab; wherein the track is shaped and positioned to engage the second tab and limit motion of the cardboard tray to substantially linear motion relative to the cardboard container.   
     
     
         6 . The package of  claim 1 , wherein:
 at least a portion of the cardboard tray is corrugated and has a thickness of at least 0.2 centimeters; and   the cardboard tray is formed by folding a cardboard sheet at the portion having the thickness of at least 0.2 centimeters to form the first resilient member.   
     
     
         7 . A method of making a cardboard package, the method comprising:
 providing a first cardboard sheet;   providing a second cardboard sheet;   folding the first cardboard sheet into a container, the container having a proximal end, a distal end, and a first wall extending between the proximal and distal ends;   forming a first recess in the first wall;   providing a first protrusion on the first wall, the first protrusion extending inwardly from the first wall, the first protrusion positioned proximal of the first recess; and   folding the second cardboard sheet into a tray, the tray having a first resilient member a first wall, the first resilient member being a tab formed out of the second cardboard sheet, the tab having at least one of a shape or a position selected such that the tab cannot extend into the first recess when the package is in a closed position,   the tab further shaped and positioned to engage the first protrusion, whereby the tray is maintained in the closed position.   
     
     
         8 . The method of  claim 1 , wherein:
 the first resilient member is disengageable from the first protrusion in response to an inward force applied to the first resilient member through the first recess.   
     
     
         9 . The method of  claim 1 , wherein:
 the first resilient member is shaped and positioned to engage an interior surface of the first wall and the first protrusion, whereby the tray is maintained in the closed position.   
     
     
         10 . The method of  claim 1 , wherein:
 folding the second cardboard sheet comprises forming the first resilient member and a second resilient member, the second resilient member being a second tab.   
     
     
         11 . The method of  claim 1 , further comprising:
 sliding the tray into the container and allowing the first resilient member to removably engage the first protrusion.   
     
     
         12 . The method of  claim 1 , wherein:
 folding the first cardboard sheet further comprises forming a track; and   folding the second cardboard sheet further comprises forming a second tab; wherein   the track is shaped and positioned to engage the second tab and limit motion of the tray to substantially linear motion relative to the container.   
     
     
         13 . The method of  claim 1 , further comprising:
 coupling a cardboard strip to an interior surface of the first wall to form the first protrusion.   
     
     
         14 . The method of  claim 1 , wherein:
 at least a portion of the second cardboard sheet is corrugated and has a thickness of at least 0.2 centimeters, the method further comprising:   folding the second cardboard sheet at the portion having the thickness of at least 0.2 centimeters to form the first resilient member.
