Protective mask of mobile phone

Abstract

The present invention relates to a protective mask of mobile phone comprising an upper cover body and a lower cover body. The upper and lower cover bodies can be joined with a front and a rear phone housing of a mobile phone, respectively, to effectively prevent abrasion of the mobile phone due to carelessness of a user, thereby preventing ill-favored scars on the mobile phone. Therefore, the deterioration of the quality of the mobile phone and the fall of its value can be avoided. Moreover, trend and fashion of the mobile phone can be achieved without the need of replacing the mobile phone. Therefore, waste of money can be avoided, and economic burden to the user can be lessened.

         7 . The protective mask of  claim 6 , wherein the protective mask further comprises at least one retainer having an extension protruding laterally inward from the integrally-formed mask body and toward and into the integrally-formed mask body interior space, wherein the at least one retainer is retained to the exterior housing at an exterior housing edge when the mask is coupled to the mobile communication device, the at least one retainer participating in retaining the integrally-formed mask body to the mobile communication device. 
     
     
         8 . The protective mask of  claim 6 , wherein the mobile communication device includes a socket for battery charging and the integrally-formed mask body defines at least a battery-charging socket opening permitting a power supply to be connected to the socket. 
     
     
         9 . The protective mask of  claim 6 , wherein the mobile communication device includes an earphone-connection socket and the integrally-formed mask body defines at least one earphone-connection socket opening permitting an earphone to be connected to the earphone-connection socket. 
     
     
         10 . A mask for attachment to a hand-held mobile phone, the mobile phone having user input and output interfaces, internal components including circuitry and a battery, and an exterior housing completely enclosing the circuitry and battery when the mobile phone is fully assembled and ready for use, the exterior housing including a first face, a second face and opposed side surfaces there between, the mask comprising:
 an integrally-formed mask body molded to conform to a shape of the exterior housing; and   inner and outer surfaces, the surfaces defining at least one opening in the integrally-formed mask body providing access to at least one of the user input and output interfaces, the integrally-formed mask body being configured such that, when the mask is attached to the mobile phone, the integrally-formed mask body is coextensive with, contours to and overlies the opposed side surfaces, with substantially no space between the mask body and the opposed side surfaces.   
     
     
         11 . The protective mask of  claim 10 , further comprising at least one inwardly-protruding flange forming a portion of the mask and engaging an edge of the exterior housing when the protective mask is coupled to the mobile phone, the flange-and-edge engagement participating in retaining the mask to the mobile phone.
