(57) 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 tear phone housings 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 ofits 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.

SUMMARY OF THE INVENTION 

The primary object of the present invention is to provide a 

protective mask of mobile phone to effectively prevent abrasion of a 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. 

45 can be joined with a rear phone housing 42 of the mobile 

phone 40, as shown in FIG. 4. The lower cover body 30 has a 

gap 31 to retain an antenna 43 of the mobile phone 40, as 

shown in FIG. 3.A plurality of cavities 32 are disposed beside 

the gap 31 of the lower cover body 30. The cavities 32 can 

The secondary object of the present invention is to provide 

a protective mask of mobile phone so that trend and fashion of 

50 correspond to an earphone cavity 44, an incoming-call 

informing light 45 and so on of the mobile phone 40 so that a 

user can conveniently use the functions of the mobile phone 

40. 

a mobile phone can be achieved without the need of replacing 55 

the mobile phone. Therefore, waste of money can be avoided, 

and economic burden to the user can be lessened. 

To achieve the above objects, the present invention provides a protective mask of mobile phone comprising an upper 

cover body and a lower cover body. The upper and lower 60 

cover bodies are integrally formed by means of mold ejection 

of plastic. Patterns, types, or nameplates can be printed on the 

upper and lower cover bodies. The upper and lower cover 

bodies can sheathe a mobile phone therein. A gap, cavities, 

and slots corresponding to an antenna, an earphone cavity, an 65 

incoming-call informing light and so on of the mobile phone 

are disposed on the lower cover body so that a user can 

Finger recessions 33 are respectively disposed at two sides 

of the lower cover body 30 so that a user can easily unfold the 

pivotally joined front phone housing 41 and rear phone housing 42 to receive a call or operate the mobile phone 40, as 

shown in FIG. 6. The finger recessions 33 can also let the user 

conveniently separate the mobile phone 40 and the lower 

cover body 30 for performing operations such as replacing a 

battery (not shown) of the mobile phone 40. A plurality of 

holes 34 are disposed at one side of the lower cover body 30. 

The holes 34 can correspond to function keys (not shown) of 

the-mobile phone 40 so that the user can successfully receive 

a call or set functions. 

A bottom of the lower cover body 30 has a slot 35, which 

can correspond to a socket 46 (shown in FIG. 5) of the mobile

As shown in FIG. 7, a different upper cover body 20 and a 

different lower cover body 30 are matched according to the 

outer look of a different mobile phone 40 so as to satisfy users 

having different mobile phones 40. The connection and disposition ways are the same as the above first embodiment of
