Claim 1
Independent Claim
325 words
A protective cover for a toothbrush of the type having a handle connected to a head portion with bristles extending from one side thereof comprising a housing forming an elongated chamber which is of a size to enclose the head portion of said toothbrush, said housing having an elongated generally cylindrical portion, said cylindrical portion having a first end which is open to provide a first opening and having a second end which is closed by a first transverse wall which extends normal to the axis of said cylindrical portion, a pair of converging walls which are generally tangential to said cylindrical portion and form a bristle enclosing portion of said housing which is in open communication with said cylindrical portion, said bristle enclosing portion having a second transverse wall which is parallel to said first transverse wall and adjacent the first end of said cylindrical portion, said bristle enclosing portion of said housing having one end which is adjacent said first transverse wall and open to provide a second opening in said elongated chamber, a pair of parallel spaced inwardly directed ribs on opposed faces of said converging walls to support the bristles of said toothbrush, said first opening in said first end of said cylindrical portion being of a size to receive said head portion of said toothbrush and said second opening in said bristle enclosing portion being sufficiently small to prevent said head portion of said toothbrush from passing therethrough, said bristle enclosing portion of said housing having an elongated cylindrical edge which interconnects said converging walls, said cylindrical edge having an axis which is parallel to and spaced from the axis of said cylindrical portion of said housing, said spaced inwardly directed ribs supporting said bristles in spaced relationship to said cylindrical edge and retaining the head portion and bristles on one side of the ribs to increase the exposure of the bristles to air for drying said bristles after brushing.

Dependent Claim
20 words
The protective cover of claim 1 wherein said cylindrical portion and said cylindrical edge are formed with lengthwise extending serrations.
Claim 4
Dependent Claim
41 words
The protective cover of claim 1 wherein said first and second transverse walls are displaced laterally from each other whereby said housing may be molded with the parting lines at said transverse walls with no side cores required in the mold.
