Abstract
Abstract An elongated handle, of rectangular cross-section, has a round, flatted brush head mounted at either one end or both ends. The brush head, according to the invention is fabricated from an originally linear, twisted wire frame having a central core portion which secures diametral bristles which effectively project radially from the core portion, and free end portions. The core portion is formed into a circular core, with the free end portions extending transversely and being secured in an axial recess in the handle. The formed brush head, then, approximates a spherical head having opposite flatted sides. The handle end to which a head is secured is preferably bent at an obtuse angle, with the plane of one head core being transverse to the handle plane defined by the main handle portion and bent handle portion. When a second head of similar construction is mounted at the opposite end of the handle, the plane of the second head core is coincident with the above mentioned handle plane. Alternatively one head is a conventional toothbrush head.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
137 words
A brush for use in brushing of teeth and gums comprising an elongated narrow handle and an enlarged brush head disposed at one end of said handle; said brush head dimensioned to be fully received within the mouth of the user; said head comprising a ring-shaped, generally planar, twisted-wire core with bristles radiating outwardly in all directions from the wire of said core; said radiating bristles being of generally uniform length, and of sufficient length to enter embrasures between the teeth; said core being of a diameter that said head has substantially no opening at the center; said brush head thereby defining opposite generally flat faces, parallel with said core plane, and a rounded peripheral surface; and said bristles having a uniform thickness, and having a thickness in the range of about 0.001 inch to 0.005 inch.
Claim 2
Dependent Claim
137 words
A brush for use in brushing of teeth and gums comprising an elongated narrow handle and an enlarged brush head disposed at one end of said handle; said brush head dimensioned to be fully received within the mouth of the user; said head comprising a ring-shaped, generally planar, twisted-wire core with bristles radiating outwardly in all directions from the wire of said core; said radiating bristles being of generally uniform length, and of sufficient length to enter embrasures between the teeth; said core being of a diameter that said head has substantially no opening at the center; said brush head thereby defining opposite generally flat faces, parallel with said core plane, and a rounded peripheral surface; and said bristles having a uniform thickness, and having a thickness in the range of about 0.001 inch to 0.005 inch.
Claim 3
Dependent Claim
40 words
A brush as set forth in claim 1 said handle comprising a major linear portion; and said head being disposed with its core plane coincident with the axis of said major linear portion, and offset from said major linear portion.
Claim 4
Dependent Claim
35 words
A brush as set forth in claim 1 said handle comprising a major linear portion; and said head being disposed with its core plane inclined at an obtuse angle relative to said major linear portion.
Claim 5
Dependent Claim
34 words
A brush as set forth in claim 2 a second head disposed at the other end of said handle with its core plane inclined at an obtuse angle relative to said major linear portion.
Claim 6
Dependent Claim
31 words
A brush as set forth in claim 2 said handle including a minor linear portion at said one end thereof formed at an obtuse angle relative to said major linear portion.
Claim 7
Dependent Claim
182 words
A brush for teeth and gums comprising an elongated handle and first and second generally flat, rounded brush heads disposed at opposite ends of said handle; said heads each comprising a round generally planar core with bristles radiating outwardly in all directions from said core, to define opposite generally flat brush faces, parallel with the plane of the core, and a rounded peripheral surface; said handle comprising a major linear portion, and first and second minor linear portions at the opposite ends thereof; the axes of each of said minor linear portions being disposed at an obtuse angle relative to the axis of said major linear portion, with said major and minor linear portion axes being disposed in a common plane; said first brush head being disposed at one of said minor linear portions, with its core plane generally perpendicular to said handle common plane and inclined at an obtuse angle relative to said major linear portion; and said second brush head being disposed at the other of said minor linear portions, with its core plane coincident with said common handle plane.
Claim 8
Dependent Claim
182 words
A brush for teeth and gums comprising an elongated handle and first and second generally flat, rounded brush heads disposed at opposite ends of said handle; said heads each comprising a round generally planar core with bristles radiating outwardly in all directions from said core, to define opposite generally flat brush faces, parallel with the plane of the core, and a rounded peripheral surface; said handle comprising a major linear portion, and first and second minor linear portions at the opposite ends thereof; the axes of each of said minor linear portions being disposed at an obtuse angle relative to the axis of said major linear portion, with said major and minor linear portion axes being disposed in a common plane; said first brush head being disposed at one of said minor linear portions, with its core plane generally perpendicular to said handle common plane and inclined at an obtuse angle relative to said major linear portion; and said second brush head being disposed at the other of said minor linear portions, with its core plane coincident with said common handle plane.
Claim 9
Dependent Claim
101 words
A brush as set forth in claim 1 said brush head being formed from an initially linear frame of wire members twisted on each other, with radially extending bristles fixedly secured in place therebetween along a length of the frame intermediate its ends defining a core portion of said frame; said frame including free end portions; said frame core portion being formed to a generally planar, circular ring with bristles of said brush head projecting generally radially outward from the axis of said core ring; said brush head being secured to said handle by means of said frame free end portions.
Claim 10
Dependent Claim
57 words
A brush as set forth in claim 7 said head frame free end portions projecting transversely from said frame ring in side-by-side relation; said handle having an axial recess in one end to receive said frame end portions; and said frame end portions being secured within said recess whereby said head is rigidly fixed to said handle.
Claim 11
Dependent Claim
17 words
A brush as set forth in claim 1 said bristles having a thickness of about 0.003 inch.
