Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
171 words
An oral hygiene device comprising, a. fluid discharge means having a fluid outlet portion, b. brush means, and c. means pivotally interconnecting said brush means to said fluid discharge means to permit rotational movement of said brush means relative to said fluid discharge means for rotating said brush means to a first limit position whereat said brush means and said fluid outlet portion are disposed adjacent one another and to a second position whereat said brush means and fluid outlet portion are spaced away from one another to facilitate independent use of said fluid outlet portion for oral hygiene purposes. d. said brush means including a stem having a first surface with bristles provided thereon and a second surface opposite to said first surface and having a through opening extending from said first surface to said second surface, and said fluid discharge means including an elongated conduit having a discharge nozzle at one end in communication with said opening when said brush member is pivotally rotated to said first limit position.
Claim 2
Dependent Claim
171 words
An oral hygiene device comprising, a. fluid discharge means having a fluid outlet portion, b. brush means, and c. means pivotally interconnecting said brush means to said fluid discharge means to permit rotational movement of said brush means relative to said fluid discharge means for rotating said brush means to a first limit position whereat said brush means and said fluid outlet portion are disposed adjacent one another and to a second position whereat said brush means and fluid outlet portion are spaced away from one another to facilitate independent use of said fluid outlet portion for oral hygiene purposes. d. said brush means including a stem having a first surface with bristles provided thereon and a second surface opposite to said first surface and having a through opening extending from said first surface to said second surface, and said fluid discharge means including an elongated conduit having a discharge nozzle at one end in communication with said opening when said brush member is pivotally rotated to said first limit position.
Claim 3
Dependent Claim
14 words
