Unit dose oral cleaning device and product dispensing system
An oral cleaning device includes an elongated, hollow body, a cleaning head, and a neck portion extending between the hollow body and the cleaning head. The neck portion forms a fluid channel between the hollow body and the cleaning head and the cleaning head includes at least one opening in fluid communication with the fluid channel. The device further includes a plunger located within the hollow body, movable between a first position and a second position, and a solution chamber formed within the hollow body which contains a cleaning solution and is in fluid communication with the fluid channel in the hollow neck portion. A cleaning end of the plunger is configured to move the cleaning solution in the solution chamber through the fluid channel and through the at least one opening in the cleaning head when the plunger is moved from the first position toward the second position.
1. A method of using an oral cleaning device for oral care, comprising:
providing an oral cleaning device comprising:
an elongated, hollow body having a bottom end and a cleaning end;
a cleaning head;
a neck portion extending between the cleaning end of the hollow body and the cleaning head;
wherein the neck portion forms a fluid channel between the hollow body and the cleaning head and wherein the cleaning head includes at least one opening in fluid communication with the fluid channel;
a hollow plunger located within the hollow body, wherein the plunger comprises a seal at a first end of the plunger proximate the cleaning end of the hollow body so as to form an airtight closure across the first end of the plunger, and wherein the plunger is movable between a first position proximate the bottom end and a second position proximate the cleaning end; and
a solution chamber formed within the hollow body at the cleaning end, wherein the solution chamber contains a cleaning solution and is in fluid communication with the fluid channel in the neck portion; and
moving the plunger from the first position toward the second position, thereby forcing the cleaning solution in the solution chamber through the fluid channel in the hollow neck portion and through the at least one opening in the cleaning head; and
providing suction in the hollow plunger, and wherein moving the plunger to the second position causes a break in the seal such that suction is further provided through the fluid channel and through the at least one opening in the cleaning head.
2. The method of claim 1 , wherein providing suction in the hollow plunger comprises providing the oral cleaning device with a vacuum port located at a bottom end of the plunger and a suction channel formed in the hollow plunger.
3. The method of claim 1 , wherein the oral cleaning device further comprises an opening in the hollow body and a suction activation opening extending between the suction channel and an exterior of the hollow body through the opening in the hollow body; and
further comprising covering the suction activation opening so as to provide suction from the vacuum port to the cleaning head.
4. The method of claim 1 , wherein the oral cleaning device further comprises a piercing element which pierces the seal when the plunger is moved to the second position.
