Oral care implement having multiple soft tissue cleaner components

摘要

An oral care implement with a soft tissue cleaner. The inventive oral care implement comprises different kinds of soft tissue cleaners that offer expanded in-mouth cleaning. In one aspect, the invention can be an oral care implement comprising: a handle; a head having a structural body having a front surface and a rear surface opposite the front surface; a basin formed into the rear surface of the structural body, the structural body comprising a protuberance extending upward from a recessed floor of the basin, the basin surrounding the protuberance; a first cleaner formed of a resilient material for cleansing soft oral tissue located within the basin, the protuberance of the structural body extending through a central hole of the first cleaner; and a second cleaner formed of a resilient material for cleansing soft oral tissue, the second cleaner located on the protuberance of the structural body.

主权项

1. A method of manufacturing a head of an oral care implement, the method comprising:
a) forming a structural body of the head out of a hard plastic, the structural body having a front surface, a rear surface, a basin formed into the rear surface, and a protuberance extending upward from a recessed floor of the basin, the basin surrounding the protuberance; b) injecting a first shot of thermoplastic elastomer via a first port into the basin of the structural body of the head to form a first cleaner for cleansing soft oral tissue surrounding the protuberance; and c) injecting a second shot of a thermoplastic elastomer via a second port into the protuberance of the structural body of the head to form a distinct second cleaner spaced and isolated from the first cleaner for cleansing soft oral tissue.
