Bag with protective case

Abstract

Bags may include a protective case having a first enclosure and a second enclosure each defining a compartment for storing fragile or expensive items. The protective case may be disposed on the top end of the bag. The first enclosure may be partially or fully disposed within the bag, and the second enclosure may be hingedly connected to the first enclosure and rotatable between an open position and a closed position. Portions of the protective case may include support ribs to provide rigidity to the structure without adding substantial amounts of weight to the bag.

What is claimed is: 
     
         1 . A bag, comprising:
 a top end;   a bottom end;   a body portion defining a main compartment disposed between the top end and the bottom end; and   a protective case disposed at the top end, the protective case comprising:
 a first enclosure defining a first compartment, the first enclosure comprising a bottom portion, a sidewall extending from the bottom portion, and a first perimeter defining an opening, and 
 a second enclosure defining a second compartment, the second enclosure comprising a second perimeter having a first edge hingedly coupled to the first enclosure, wherein the second enclosure is rotatable between an open position and a closed position. 
   
     
     
         2 . The bag of  claim 1 , wherein the bottom portion of the first enclosure separates the first compartment from the main compartment. 
     
     
         3 . The bag of  claim 1 , wherein the bottom portion of the first enclosure comprises one or more support ribs. 
     
     
         4 . The bag of  claim 1 , further comprising an attachment flap coupled to the bottom portion of the first enclosure, wherein the attachment flap is disposed in the main compartment and coupled to an interior surface of the main compartment. 
     
     
         5 . The bag of  claim 1 , further comprising a zipper configured to couple the first perimeter of the first enclosure with the second perimeter of the second enclosure. 
     
     
         6 . The bag of  claim 1 , further comprising a cover configured to be disposed over the opening of the first enclosure. 
     
     
         7 . The bag of  claim 1 , wherein the volume of the first compartment is greater than the volume of the second compartment. 
     
     
         8 . The bag of  claim 1 , wherein in the closed position, the second enclosure is disposed over the first enclosure. 
     
     
         9 . The bag of  claim 1 , wherein the second enclosure comprises a substantially rigid member, wherein the substantially rigid member is more rigid than the body portion of the bag. 
     
     
         10 . A bag, comprising:
 a protective case, comprising:
 a first enclosure defining a first compartment, the first enclosure comprising a bottom portion, a sidewall extending from the bottom portion, and a first perimeter; and 
 a second enclosure defining a second compartment, the second enclosure comprising a second perimeter having a first edge hingedly coupled to the first perimeter, 
 wherein the second enclosure is disposed over the first enclosure in a closed position. 
   
     
     
         11 . The bag of  claim 10 , wherein in an open position, the first and second compartments of the protective case are accessible by a user. 
     
     
         12 . The bag of  claim 10 , wherein a second edge of the second enclosure is disposed opposite the first edge, wherein the distance from the volumetric center of the second compartment to the first edge is less than the distance from the volumetric center of the second compartment to the second edge. 
     
     
         13 . The bag of  claim 10 , wherein the second enclosure comprises a first angled portion extending in a first direction and a second angled portion extending in a second direction. 
     
     
         14 . The bag of  claim 13 , wherein the first angled portion and the second angled portion form an obtuse angle. 
     
     
         15 . The bag of  claim 13 , wherein an intersection point of the first angled portion and the second angled portion is closer to the first edge of the second perimeter than a second edge of second perimeter disposed opposite the first edge. 
     
     
         16 . The bag of  claim 10 , further comprising a hinge member coupled to the first enclosure and the second enclosure, wherein the hinge member is configured to limit the range of rotation of the second enclosure relative to the first enclosure. 
     
     
         17 . The bag of  claim 10 , wherein the bottom portion comprises one or more support ribs disposed between a top surface of bottom portion and a bottom surface of bottom portion. 
     
     
         18 . The bag of  claim 10 , wherein a cover is coupled around the second perimeter of the second enclosure, the cover comprising a first elastic portion and a second elastic portion, wherein the first elastic portion and the second elastic portion overlap. 
     
     
         19 . A method of attaching a protective case to a bag, comprising:
 inserting a first enclosure into an opening of the bag, wherein the first enclosure comprises:
 a bottom portion having a top surface, a bottom surface, and a support rib, 
 a sidewall coupled to the bottom portion and extending above the top surface of the bottom portion, and 
 an attachment flap coupled to the bottom portion and extending beneath the bottom surface of the bottom portion; and 
   attaching the attachment flap to an interior surface of the bag.   
     
     
         20 . The method of  claim 19 , wherein the attachment flap is configured to secure the bottom portion of the first enclosure in a substantially fixed position. 
     
     
         21 . The method of  claim 19 , further comprising attaching the sidewall to the interior surface of the bag. 
     
     
         22 . The method of  claim 19 , further comprising attaching a second attachment flap to the interior surface of the bag. 
     
     
         23 . The method of  claim 19 , further comprising attaching an edge of a second enclosure to the first enclosure, wherein the second enclosure is rotatable relative to the first enclosure.
