Filed:

Nov 9, 2000

Appl. No.:

09/710777

Inventors:

David T. Carroll - Schofield WI

Assignee:

Preventive Dental Specialties, Inc. - Weston WI

International Classification:

A45D 4000

US Classification:

132286, 422300, 215309

Abstract:

Multiple plastic trays are covered with pivotable lids. Each tray is divided into distinct compartments into which infant and toddler toothbrushes, teething rings, pacifiers, or other such personal hygiene products may be placed. The lid is punctured by an array of air holes, which allow moisture to escape from the covered tray, while at the same time protecting the tray contents from contamination. The covered trays are received within an open front rack in a vertically spaced arrangement. Air cavities defined between stacked trays permit natural air flow over the trays, and the removal of moisture from the tray contents. A fan may be attached to the rear of the rack to blow air over the lids and to draw the moist air from within the compartments through the lid air holes.

Inventors:

David T. Carroll - Schofield WI

International Classification:

US Classification:

15105

Abstract:

A plastic looped handle has a front ring with two parallel members connected by a front brush head member. Bristles in curved rows extend from one side of the brush head for brushing of teeth, while convex protrusions extend from the other side of the brush head for tongue cleaning. A center bar extends across the front ring, and a rear ring extends rearwardly from the center bar. A front opening is defined between the front ring and the center bar and a rear opening is defined between the rear ring and the center bar. Both openings are sufficiently large to receive at least two human fingers therethrough. The center bar defines an angle with one of the front members of less than 90 degrees, to thereby define a wedge space, into which the hand of a user may be inserted and wedged to thereby retain control of the toothbrush. The two front members are spaced from one another a width to permit the insertion of the brush head into a user's mouth, while the rear ring is substantially wider than the front ring, to thereby permit the support of the brush within the non-extended fingers of a crabbed hand. The brush is particularly suited for use by those who have lost some gripping abilities, and by those who must brush the teeth of others.
