Travel case

Abstract

An example of a carrying case includes an inner cover and an outer cover. The inner cover includes a first end and a second end. The outer cover also includes a first end and a second end. The first end of the outer cover is rotatably connected to a first pivot point at the first end of the inner cover and the second end of the outer cover is rotatably connected to a second pivot point at the second end of the inner cover. The outer cover can be rotated around the inner cover along the longitudinal axis of case to open and close the carrying case. The inner and outer covers form a storage compartment.

1 . A portable carrying case comprising:
 an inner cover having a first end and a second end; and   an outer cover having a first end and a second end, the first end of the outer cover being rotatably connected to a first pivot point at the first end of the inner cover, and the second end of the outer cover being rotatably connected to a second pivot point at the second end of the inner cover;   wherein the outer cover is rotatable relative to the inner cover along a longitudinal axis of the inner and outer covers;   wherein the outer cover is rotatable to an open position relative to the inner cover and the outer cover is rotatable to a closed position relative to the inner cover;   wherein the inner cover is received by the outer cover when the outer cover is rotated to the open position relative to the inner cover;   wherein an inner surface of the outer cover and an inner surface of the inner cover form a storage compartment when the outer cover is in a closed position relative to the inner cover; and   wherein at least one of the inner cover or the outer cover includes a retention mechanism to retain the inner cover and the outer cover in the closed position.   
     
     
         2 . The carrying case of  claim 1  wherein the inner cover defines a longitudinal opening to provide access through the inner cover to a chamber defined by the inner cover. 
     
     
         3 . The carrying case of  claim 1  wherein the inner cover and outer cover comprise a portion forming an asymmetrical, approximately dual-frustoconical shape. 
     
     
         4 . The carrying case of  claim 3 , wherein the inner cover and outer cover comprise a portion forming dual-truncated obovoids. 
     
     
         5 . The carrying case of  claim 1  wherein the outer cover comprises a portion forming approximately one half of a cylinder bisected along the longitudinal axis of the cylinder. 
     
     
         6 . The carrying case of  claim 1  wherein the inner cover and the outer cover are rotationally symmetric. 
     
     
         7 . The carrying case of  claim 1  wherein when the outer cover is rotated to the closed position relative to the inner cover, the storage comportment is surrounded by the inner cover and the outer cover. 
     
     
         8 . The carrying case of  claim 1  wherein when the outer cover is rotated to the open position relative to the inner cover, the storage compartment is accessible through an opening in the inner cover and an opening in the outer cover. 
     
     
         9 . The carrying case of  claim 1  wherein the retention mechanism also retains the outer cover in the open position relative to the inner cover. 
     
     
         10 . The carrying case of  claim 9  wherein the retention mechanism comprises magnets, wherein the inner cover includes a first set of magnets and the outer cover includes a second set of magnets, the first set of magnets being aligned with the second set of magnets when the outer cover is in the open position relative to the inner cover. 
     
     
         11 . The carrying case of  claim 9  wherein the retention mechanism comprises a first retention element on one of the covers and a second retention element on the other of the covers, and wherein frictional force between the first retention element and the second retention element maintains the outer cover in the closed position. 
     
     
         12 . The carrying case of  claim 11  wherein the first retention mechanism comprises a recess and the second retention mechanism comprises a knob corresponding to the recess. 
     
     
         13 . The carrying case of  claim 1  further comprising a retaining member affixed to an interior wall of the storage compartment configured to retain an object disposed in the storage compartment in place when the object is inserted into the storage compartment. 
     
     
         14 . The carrying case of  claim 13  wherein the retaining member comprises a deformable material that conforms to the shape of the object stored in the storage compartment of the carrying case. 
     
     
         15 . The carrying case of  claim 1  wherein outer surfaces of the outer cover and the inner cover include a soft-touch coating. 
     
     
         16 . The carrying case of  claim 1  wherein the inner cover and the outer cover surround the storage compartment when the outer cover is in a closed position relative to the inner cover. 
     
     
         17 . A portable carrying case for a Venturi apparatus comprising:
 an inner cover having a first end and a second end;   an outer cover having a first end and a second end, the first end of the outer cover being rotatably connected to a first pivot point at the first end of the inner cover, and the second end of the outer cover being rotatably connected to a second pivot point at the second end of the inner cover,   wherein the outer cover is rotatable relative to the inner cover along a longitudinal axis of the inner and outer covers,   wherein the outer cover is rotatable to an open position relative to the inner cover and the outer cover is rotatable to a closed position relative to the inner cover,   wherein the inner cover is received by the outer cover when the outer cover is rotated to the open position relative to the inner cover,   wherein an inner surface of the outer cover and an inner surface of the inner cover form a storage compartment when the outer cover is in the closed position relative to the inner cover, the storage compartment having a shape that approximates the shape of the Venturi device,   wherein the storage compartment receives the Venturi device, and   wherein the inner cover and the outer cover surround the Venturi device when the outer cover is in the closed position relative to the inner cover; and   a retention mechanism to retain the inner cover and the outer cover in the closed position.
