The input port permits brushing by-products to pass through the input port and into the cavity while restricting passage of the brushing by-products outward from the cavity. In one form, the toothbrush device includes an elongated handle with a reservoir having at least a portion disposed within the handle. The reservoir is sized to hold a predetermined amount of oral care product, and a mouthpiece is in fluid communication with the reservoir to discharge the oral care product from the reservoir. ## Claims ### Claim 1 An oral care device comprising: a body; an oral care implement connected to the body; an oral care byproduct cavity of the body; an inlet in communication with the oral care byproduct cavity and permitting oral care byproducts to pass into the oral care byproduct cavity; and an absorbent material in the oral care byproduct cavity. ### Claim 2 (depends on 1) The oral care device of claim 1 wherein the body includes an air vent in communication with the oral care byproduct cavity. ### Claim 3 (depends on 2) The oral care device of claim 2 further comprising a wall in the oral care byproduct cavity separating the absorbent material from the air vent. ### Claim 4 (depends on 1) The oral care device of claim 1 wherein the body has a wall defining a portion of the cavity; and at least one spacer extending between the wall and the absorbent material to space at least a portion of the absorbent material a distance away from the wall. ### Claim 5 (depends on 4) The oral care device of claim 4 wherein the absorbent material includes a leading end portion and a trailing end portion, the leading end portion being closer to the inlet than the trailing end portion; and the at least one spacer spaces the leading end portion of the absorbent material a distance away from the wall of the body that is greater than a distance between the trailing end portion of the absorbent material and the wall of the body. ### Claim 6 (depends on 1) The oral care device of claim 1 wherein the oral care byproduct cavity includes an inner surface extending about the absorbent material; and a harness separates a portion of the absorbent material from the inner surface. ### Claim 7 (depends on 6) The oral care device of claim 6 wherein the harness includes a plurality of arms and gaps between the arms that permit oral care byproducts to travel through the gaps. ### Claim 8 (depends on 1) The oral care device of claim 1 wherein the body includes a wall disposed between the inlet and the absorbent material. ### Claim 9 (depends on 1) The oral care device of claim 1 wherein the inlet includes a one-way input port permitting oral care byproducts to pass into the oral care byproduct cavity and restricting passage of the oral care byproducts outward from the oral care byproduct cavity. ### Claim 10 (depends on 1) The oral care device of claim 1 wherein the inlet includes a plurality of movable flaps. ### Claim 11 (depends on 1) The oral care device of claim 1 wherein the body includes assembled first and second body portions. ### Claim 12 (depends on 11) The oral care device of claim 11 wherein the assembled first and second body portions define the oral care byproduct cavity. ### Claim 13 (depends on 1) The oral care device of claim 1 wherein the body includes a handle, a head, and a neck connecting the handle and the head; and the oral care implement includes a plurality of bristles supported by the head. ### Claim 14 (depends on 1) The oral care device of claim 1 further comprising a reservoir containing an oral care product, an outlet in communication with the reservoir, and a suction-drawn piston of the reservoir configured to be drawn toward the outlet in response to suction being applied to the outlet. ### Claim 15 (depends on 1) The oral care device of claim 1 wherein the oral care implement includes a plurality of bristles. ### Claim 16 (depends on 1) The oral care device of claim 1 wherein the oral care implement includes a toothpick. ### Claim 17 (depends on 1) The oral care device of claim 1 further comprising a reservoir containing a liquid, an outlet in communication with the reservoir, and a suction-drawn piston of the reservoir configured to be drawn toward the outlet in response to suction being applied to the outlet.
