Interproximal brush device having hinged brush retainer cap

Claim 2

An interproximal brush handle comprising: (a) an elongated handle having a grip portion and an end portion including opposed side surfaces, a bottom surface and a transverse hole; (b) a cap pivotally mounted to the end portion and including a section adapted and arranged for communication with the end portion to cover at least part of the end portion surface; (c) a longitudinal groove carried by the end portion or the cap and adapted and arranged for communication with the transverse hole; and (d) means for releasably attaching the section to the end portion.

Claim 3

A handle of claim 1 where the end portion is bent upwardly at an angle of from about 5° to about 25° with respect to the longitudinal axis of the handle.

Claim 4

A handle of claim 1 where the groove is carried by the end portion.

Claim 5

A handle of claim 1 where the groove is carried by the cap.

Claim 6

A handle of claim 1 where the thickness of the end portion is less than the thickness of the grip portion.

Claim 7

A handle of claim 1 where the section comprises an opening having an inner surface which corresponds to the cross-sectional shape of the end portion and includes opposed side surfaces terminating at opposed side edges and the side surfaces are dimensioned to extend downwardly at least to the center of the end portion when the section is attached to the end portion.

Claim 8

A handle of claim 6 where the inner surface has a cross-sectional shape corresponding to the cross-sectional shape of the opposed end portion.

Claim 9

A handle of claim 7 where the inner surface is curved in shape.

Claim 10

A handle of claim 7 where the inner surface is cylindrical in shape.

Claim 11

A handle of claim 7 where the inner surface is rectangular in shape.

Claim 12

A handle of claim 6 where the means for releasably attaching the section to the end portion includes a section having an inner surface having opposed side surfaces terminating at opposed flexible side edges spaced apart from each other by a dimension which causes at least a portion of the edges to flex outwardly on engagement with opposed end portion side surfaces and the end portion has a cross-sectional shape whereby the flexible side edges can relax inwardly after flexing outwardly.

Claim 13

A handle of claim 11 where the end portion has a cross-sectional shape in which the thickness decreases toward the end portion bottom surface.

Claim 14

A handle of claim 1 where the means for releasably attaching the section to the end portion includes a bar adapted for latchable engagement with a recess.

Claim 15

A handle of claim 13 where the bar is carried by the cap.

Claim 16

A handle of claim 13 where the bar is carried by the end portion.

Claim 17

A handle of claim 1 where the section includes an opening having an inner surface including opposed side surfaces terminating at opposed side edges and the means for releasably attaching the section to the end portion includes ribs and recesses arranged and adapted for engagement with each other when the section is attached to the end portion.

Claim 18

A handle of claim 1 where the section includes an opening having an inner surface including opposed side surfaces terminating at opposed side edges and the means for releasably attaching the section to the end portion includes projections arranged at the opposed side edges extending toward each other and adapted for engagement with the end portion bottom surface.

Claim 19

A handle of claim 1 including an interproximal brush having a stem which is inserted through the hole and retained in the groove.

Claim 20

A handle of claim 1 including a second end portion having a tapered transverse hole to retain a rigid or flexible insert for cleaning between teeth or gums.

Claim 21

A handle of claim 19 where the insert is rigid.

Claim 22

An interproximal brush handle comprising (a) an elongated handle having a grip portion and an end portion including opposed side surfaces, a bottom surface, a transverse hole and a longitudinal groove adapted and arranged for communication with the transverse hole; (b) a cap pivotally mounted to the end portion and including a section adapted and arranged for communication with the end portion, said section including an inner surface including opposed side surfaces terminating at opposed side edges and said inner surface having a cross-sectional shape corresponding to the cross-sectional shape of the opposed end portion; and (c) means for releasably attaching the section to the end portion.

Claim 23

An interproximal brush handle comprising (a) an elongated handle having a grip portion and an end portion including opposed side surfaces, a bottom surface, a transverse hole and a longitudinal groove adapted and arranged for communication with the transverse hole; (b) a cap pivotally mounted to the end portion and including a section adapted and arranged for communication with the end portion, said section including an inner surface including opposed side surfaces terminating at opposed side edges and said inner surface having a cross-sectional shape corresponding to the cross-sectional shape of the opposed end portion; and (c) means for releasably attaching the section to the end portion.

Claim 24

A handle of claim 21 where the end portion is bent upwardly at an angle of from about 5° to about 25° with respect to the longitudinal axis of the handle.

Claim 25

A handle of claim 21 where the means for releasably attaching the section to the end portion includes a section having flexible opposed side edges spaced apart from each other by a dimension which causes at least a portion of the edges to flex outwardly on engagement with opposed end portion side surfaces and the end portion has a cross-sectional shape whereby the flexible side edges can relax inwardly after flexing outwardly.

Claim 26

A handle of claim 23 where the end portion has a cross-sectional shape in which the thickness decreases toward the end portion bottom surface.

Claim 27

A handle of claim 21 including an interproximal brush having a stem which is inserted through the hole and retained in the groove.
