Abstract
Abstract A pocket hair brush having a self-contained cover in an integral unit formed of a thermoplastic polymeric resin and includes a backing plate flexible rectangular panel having integrally formed bristles projecting from a face thereof. Rectangular side panels are joined to the backing plate by self-hinges and rectangular wing panels are joined to the side panel outer side edges and form dihedral angles therewith. A short notch is medially formed along the junction between one of the side and wing panels and extensions with enlarged ends are medially formed at opposite sides of the other wing panel. The side and wing panels are swingable between a closed position covering the bristles and releasably locked by coupling of one extension and the slot and an open rearwardly directed handle defining position with the other extension engaging the slot.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
137 words
A brush and cover device integrally formed of a polymeric resin comprising a flexible intermediate rectangular panel having bristles projecting upwardly from the top face thereof, a pair of side panels integral with and extending along the sides of said intermediate panel and joined thereto by self hinges of reduced thickness and swingable between a closed position upwardly along the sides of said bristles and a downwardly converging open position, wing panels extending along the outer side edges of said side panels and forming dihedral angles therewith, said wing panels overlying said bristles when said side panels are in closed position and diverging downwardly and outwardly when said side panels are in their open position and locking means integrally formed with said side panels for releasably locking said side panels in their respective open and closed positions.
Claim 2
Dependent Claim
137 words
A brush and cover device integrally formed of a polymeric resin comprising a flexible intermediate rectangular panel having bristles projecting upwardly from the top face thereof, a pair of side panels integral with and extending along the sides of said intermediate panel and joined thereto by self hinges of reduced thickness and swingable between a closed position upwardly along the sides of said bristles and a downwardly converging open position, wing panels extending along the outer side edges of said side panels and forming dihedral angles therewith, said wing panels overlying said bristles when said side panels are in closed position and diverging downwardly and outwardly when said side panels are in their open position and locking means integrally formed with said side panels for releasably locking said side panels in their respective open and closed positions.
Claim 3
Dependent Claim
39 words
The brush and cover device of claim 1 wherein said side and wing panels are substantially rectangular and the outer dihedral angles between said wing and side panels are obtuse when said side panels are in their open position.
Claim 4
Dependent Claim
34 words
The brush and cover device as in claim 1 wherein said bristles are integrally formed with said intermediate panel and the side panels are rectangular and extend along the length of said intermediate panel.
Claim 5
Dependent Claim
184 words
A brush and cover device integrally formed of a polymeric resin comprising a flexible intermediate rectangular panel having bristles projecting upwardly from the top face thereof, a pair of side panels integral with and extending along the sides of said intermediate panel and joined thereto by self hinges of reduced thickness and swingable between a closed position upwardly along the sides of said bristles and a downwardly converging open position, wing panels extending along the outer side edges of said side panels and forming dihedral angles therewith, said wing panels overlying said bristles when said side panels are in closed position and diverging downwardly and outwardly when said side panels are in their open position, locking means integrally formed with said side panels for releasably locking said side panels in their respective open and closed positions, and a coupling aperture formed at the junction of one of said wing and side panels, said locking means comprising coupling elements located along opposite sides of the other wing panel and alternatively releasably engaging said aperture when said panels are respectively in their open and closed positions.
Claim 6
Dependent Claim
184 words
A brush and cover device integrally formed of a polymeric resin comprising a flexible intermediate rectangular panel having bristles projecting upwardly from the top face thereof, a pair of side panels integral with and extending along the sides of said intermediate panel and joined thereto by self hinges of reduced thickness and swingable between a closed position upwardly along the sides of said bristles and a downwardly converging open position, wing panels extending along the outer side edges of said side panels and forming dihedral angles therewith, said wing panels overlying said bristles when said side panels are in closed position and diverging downwardly and outwardly when said side panels are in their open position, locking means integrally formed with said side panels for releasably locking said side panels in their respective open and closed positions, and a coupling aperture formed at the junction of one of said wing and side panels, said locking means comprising coupling elements located along opposite sides of the other wing panel and alternatively releasably engaging said aperture when said panels are respectively in their open and closed positions.
Claim 7
Dependent Claim
33 words
The brush and cover device of claim 4 wherein said aperture is a longitudinally extending slot and each of said coupling elements comprises a flap member terminating in a longitudinally extending enlarged head.
Claim 8
Dependent Claim
29 words
The brush and cover device of claim 5 wherein the flap member along the junction of the respective wing and side panels is longer than the other flap member.
Claim 9
Dependent Claim
43 words
The brush and cover device of claim 1 wherein said intermediate panel is upwardly convex with said bristles diverging when said side panels are in open position and is substantially concave with said bristles converging when said side panels are in closed position.
Claim 10
Dependent Claim
20 words
The brush and cover device of claim 7 wherein said intermediate panel has thicker edge portions than the center portion.
Claim 11
Dependent Claim
24 words
The brush and cover device of claim 1 including handle defining projections extending longitudinally from a pair of proximate ends of said side panels.
