JPS6468205A - Tooth cleaner of chewing type - Google Patents

Abstract

PURPOSE: To enable a user to easily and rationally clean the oral teeth when and where needed by connecting disks to the front surface and rear surface of a minor axis cylinder and forming many thorn-like projections, of which the tips are directed diagonally inward, in the respective outer peripheral parts of both disks. CONSTITUTION: The many thorn-like projections 4, 5 of which the tips are directed diagonally inward are formed on the respective outer peripheral parts of the disks 2, 3 connected to the front surface and rear surface of the minor axis cylinder 1. The thorn-like projections 6 are formed on the outer peripheral surface of the minor axis cylinder 1 as well. All these projections are integrally molded by a rubber material. The rear surface disk 3 is picked up and is put into the mouth. After the upper and lower dentitions 12, 13 are opened from each other, the front surface disk 2 is inserted deep therein and the minor axis cylinder is chewed by the dentitions 12, 13. The thorn-like projections 4, 5 are then pressed to the rear surfaces and front surfaces of the dentitions 12, 13. The projections 4 to 6 clean the tooth surfaces and the inter-dentition spacings when the chewing is repeated.
