Rotating lid lock with securing bumps

Abstract

An invented container closure system includes a first side having one or more keys, which are pieces of material shaped to stick out from a substantively smooth container or cap shape, and a corresponding second side having one or more gaps in a ledge, such that if and only if the cap is turned to the correct position relative to the container, the keys fit through the gaps and are not blocked by the ledge, and the first side may be uncoupled from the second side. Additionally, one or more flexible nubs may be positioned beneath the ledge of the second side such that channels indented into the outward surface edges of the keys of the first side fit around the nubs, allowing the nubs to laterally traverse through the channels when the sides are coupled together.

I claim: 
     
         1 . A device comprising:
 a cap, the cap having a cover element, a circular vertical wall and at least three keys, each key extending from an exterior side of the circular vertical wall and distally from a central elongate axis of the cap, wherein at least one key has an arc length greater than the remaining two keys; and   a container section defining an open volume, a circular vertical wall and a bottom, the circular vertical wall extending along a central elongate axis of the container (“container axis”) from the bottom, and at least three ledges extending from the vertical wall and toward the container axis and along a same planar circle, the three ledges defining three separate release features, wherein a first release feature matches a first key, a second release feature matches a second key, and a third release feature matches a third key, whereby the cap is detachably engaged with the container section when the three keys are positioned between the three ledges and a bottom of the container.   
     
     
         2 . The device of  claim 1 , wherein the three ledges are shaped and positioned to allow decoupling of the cap from container when the three keys of the cap are placed in one unique alignment position relative to the container. 
     
     
         3 . The device of  claim 1 , wherein the container first release feature includes a first nub positioned between the planar circle and the container bottom, and the first nub extends from the container vertical wall toward the container axis. 
     
     
         4 . The device of  claim 3 , wherein the first key includes a receiver channel through which the first nub is sized to extend through while the cap is rotating relative to the container. 
     
     
         5 . The device of  claim 4 , wherein the container second release feature includes a second nub positioned between the planar circle and the container bottom, and the second nub extends from the container vertical wall toward the container axis. 
     
     
         6 . The device of  claim 5 , wherein the second key includes a receiver channel through which the second nub is sized to extend through while the cap is rotating relative to the container. 
     
     
         7 . The device of  claim 7 , wherein the cap third release feature includes a third nub positioned between the planar circle and the container bottom, and the third nub extends from the container vertical wall toward the container axis. 
     
     
         8 . The device of  claim 7 , wherein the third key includes a receiver channel through which the third nub is sized to extend through while the cap is rotating relative to the container. 
     
     
         9 . The device of  claim 1 , wherein the container first release feature includes a first nub positioned between two ledges and the container bottom and, the first nub extends from the container vertical wall toward the container axis. 
     
     
         10 . The device of  claim 9 , wherein the container second release feature includes a second nub positioned between the two ledges and the container bottom, and the second nub extends from the container vertical wall toward the container axis. 
     
     
         11 . The device of  claim 10 , wherein the container third release feature includes a third nub positioned between two ledges and the container bottom, and the third nub extends from the container vertical wall toward the container axis. 
     
     
         12 . The device of  claim 1 , wherein a first arc length of a first key of the three keys is sized to extend through only one container release feature. 
     
     
         13 . The device of  claim 12 , wherein a second arc length of a second key of the three keys is sized to be smaller than two container release features. 
     
     
         14 . The device of  claim 13 , wherein a third arc length of a third key of the three keys is sized to be smaller than two cap container features. 
     
     
         15 . The device of  claim 1 , wherein a first arc length of a first key of the three keys and a second arc length of a second key of the three keys are within 5% of divergence. 
     
     
         16 . The device of  claim 15 , wherein a third arc length of a third key of the three keys is more than 5% longer than either the first key or the second key. 
     
     
         17 . The device of  claim 1 , wherein a first arc length of the first release feature and a second arc length of a second release feature are within 5% of divergence. 
     
     
         18 . The device of  claim 17 , wherein a third arc length of the third release feature is more than 5% longer than either the first release feature or the second release feature. 
     
     
         19 . The device of  claim 7 , wherein the second nub extends further toward the container axis than the first nub. 
     
     
         20 . The device of  claim 18 , wherein the second nub extends further toward the container axis than the third nub. 
     
     
         21 . The device of  claim 3 , wherein the first nub is substantively angled to resist positioning of the first key directly underneath the first release feature. 
     
     
         22 . The device of  claim 5 , wherein the second nub is substantively angled to resist positioning of the second key directly underneath the second release feature. 
     
     
         23 . The device of  claim 7 , wherein the third nub is substantively angled to resist positioning of the third key directly underneath the third release feature.
