An oral care implement and/or a cleaning element for an oral care implement. The cleaning element may include an annular cleaning component having an inner surface defining a cavity. The annular cleaning component may be formed from a plurality of arcuate portions with each of the arcuate portions extending from a first end to a second end and terminating in a distal end. A height of each of the arcuate portions may be greater at the second end than at the first end. The plurality of arcuate portions may be arranged in a ring so that the first end of each of the arcuate portions is adjacent to the second end of another one of the arcuate portions.

An support structure of an article that has a tamper deterrent structure. The support structure, such as a handle, includes segments that are connected by a series of connectors. Both the segments and the connectors, on their own, are designed to prevent their use as a weapon. The connectors provide structure to the segments when the support structure is used as intended but are positioned so the support structure will fail upon intentional manipulation. This manipulation causes the support structure to break into smaller pieces in the event the support structure is attempted to be fashioned into or used as a weapon.

A toothbrush including: a body, the body having a head with bristles; and a manually operated pump formed in the body, the pump having a nozzle for drawing a liquid into the body and expelling the water from the body. The nozzle can be disposed on the head on a surface opposite to a surface on which the bristles are disposed. The pump can further include: a reservoir disposed in the body for containing the liquid, the nozzle being in fluid communication with the reservoir; a shaft movably disposed in the reservoir, the shaft having a first seal substantially disposed at a free end of the shaft; and a second seal disposed in the body for sealingly engaging with an outer surface of the shaft. The first seal can be a piston a grip can be disposed at an other end of the shaft.

An oral care implement including a head and a plurality of cleaning elements which may include a first annular cleaning component and a second annular cleaning component. The first annular cleaning component may have a first inner surface defining a first cavity and a first distal end that is sloped from a first low point to a first high point. The second annular cleaning component may a second inner surface defining a second cavity and a second distal end that is sloped from a second low point to a second high point. The first annular cleaning component may located within the second cavity of the second annular cleaning component. The first and second distal ends may be sloped in opposite directions.
