Therefore, it is within the purview of a skilled artisan to select a polymer suitable for a given application.
  • the oral care instrument 1 can be formed of polypropylene materials such as those available from M.A. Industries.
  • the head 20 formed of a polypropylene material is manufactured using a sintering process.
  • the head 20 can formed at the same time as the remaining portions of the oral care instrument 1 as a single, continuous member.
  • the head 20 can be manufactured as a component that is assembled as part of the instrument 1.
  • the head 20 can then be attached through a number of techniques including welding via ultrasonics, heat staking, laser, etc. or through mechanical methods that also permit the head 20 to be removed and discarded.
  • the term "cavity” is intended to refer to an opening in the head 20, whether present in the head material itself or intentionally formed therein, that preferably does not extend all the way through the head.
  • the term “exposed surface” relates to a surface that defines the shape of the head 20 and which generally defines the boundary between the head 20 and its environment.
  • the externally exposed cavities 50 are capable of receiving and retaining one or more of the dispensable oral care agents.
  • the cavities 50 can receive these agents in a powered form, a liquid form or both.
  • the cavities 50 will receive and retain the oral care agent(s) until a predetermined amount has been received or the cavity is filled.
  • the size and shape of these cavities 50 may be varied so they can include greater amounts of an oral care agent or an oral care agent with larger or different shaped molecules.
  • the oral care instrument 1 can have cavities 50 that deliver oral care agent(s) into the mouth of a user at different rates.
  • These rates can be controlled, for example, by the size of the exposed surface area of the respective cavity 50 and contained oral care agent in the outer surface 22, 24, 26 of the head, the shape of the cavities 50, the depth of the cavities 50 and/or the characteristics of the contained oral care agent(s).
  • Adjacent cavities 50 can have different sizes in order to accommodate different amounts of oral care agent(s) or different molecular sized oral care agent(s).
  • the oral care instrument 1 can have different oral care agent release characteristics that control when and how much of each oral care agent is delivered into the oral cavity.
  • a larger thermoplastic granule size for the head 20 may preferably be selected and, where it is desired that the oral care agent(s) be dispensed more slowly, a smaller thermoplastic granule size may preferably be selected.
  • Adjacent cavities 50 within the outer surfaces of the head 20 can carry the same or different oral care agents.
  • the same void 50 can carry different oral care agents (A, B), either layered on top of each other ( Figure 5) for controlled release timing or adjacent to each other ( Figure 6) so they will react simultaneously when they come into contact with an activator.
  • the active oral care agents can function as, for example, abrasives, mouth fresheners, tooth whiteners, vitamins, anti-bacterial/anti-microbial agents, plaque dispersants, de-sensitizing agents for the mouth and teeth, anti-cavity agents, and/or combinations of these functional agents to provide individual or combined, synergistic benefits.
  • Oral care agents can also include flavorings, decorations, nutritional and body supplements such as calcium. The calcium could, for example, be provided in 1 mg single use dosages. The flavorings could be released to indicate that the oral care element 1 is functioning properly or to indicate that the instrument 1 is exhausted and ready to be disposed or recharged. Also, the oral care agents could eliminate particular enzymes from within the mouth of the user.
  • the decorations applied by the oral care agents could temporarily add coloring, sparkle, glitter and/or indicia to the teeth of the user. Further, the lack of fluid within the mouth could trigger an oral care agent, such as stimulant for the salivary gland, provided within the cavities 50. The amount and rate of delivery for these agents will depend on the amount needed and the agent being applied.
  • the oral care agents can be delivered to the cavities in a solid and/or liquid compound.
  • the material of the oral care instrument 1 is immersed in a desired liquid so that the oral care agent(s) within the liquid can flow and remain within the cavities 50. As it dries, the oral care agent 20 becomes secure within the cavities 50. It is also possible to impregnate the cavities 50 of the portion of the head 20 with desired oral care agent(s) during production. It is also understood that a spent oral care instrument, i.e., one in which the oral care agent(s) has been depleted, may advantageously be recharged with an oral care agent by immersing it again in a liquid that carries the desired oral care agent(s).
  • the cavities 50 can be replenished (recharged) on a regular basis, including daily for those instruments providing single dosages of at least one oral care agent.
  • the head 20 may be advantageously used to dispense or release the oral care agent(s) within the mouth.
  • the oral care agents will typically leach from their respective cavities 50 when they come into contact with fluids and/or chemicals within the mouth.
  • active oral care agents that have been impregnated in the head material can be released into the mouth while brushing one's teeth.
  • water and chemicals present in the mouth of a user will come into contact with the oral care agent(s) within the cavities 50 in the head 20. This will create a reaction in which the impregnated oral care agent(s) will leach out from the cavities 50 within the head 20.
  • the use of different oral care agents in cavities 50 of the same head 20 has the capability of providing a synergistic benefit to the user. This can be especially useful when there are two beneficial oral care agent(s) which, in ideal circumstances, should be kept separated from each other until the desired time of use. In this manner the oral care instrument 1 can deliver multiple benefits to the user at one time.
  • the oral care instrument 1 is also able to deliver the benefits of a dentifrice by impregnating the head material with the chemicals and abrasives found in toothpaste, for example.
  • At least one of the dispensed oral care agents could also operate as a catalyst or enhancer for the toothpaste or other agents introduced into the mouth.
  • this oral care instrument 1 it may be possible to deliver the benefits of a chemical, such as chlorhexidine for example, in a more efficacious manner.
  • the delivery member 100 discussed above can provide or include the oral care agents discussed above and also function as a wear indicator. This member 100 can be located at any position on the head 20 and can provide notice to the user when the oral care agent is depleted. In a non-limiting illustrative embodiment, the delivery member 100 is shown as a strip 102 on the second surface 24. The delivery member 100 can have any shape and be located on or in any surface(s) on the instrument 1 that can be viewed by the user. In addition to identifying when the instrument 1 needs to be discarded or recharged, the delivery member 100 can also include and deliver at least one of the above-discussed oral care agents within the oral cavity.
  • the delivery member 100 is removable and one or more replacement strips 102 can be applied in its place, in series or in parallel, to perform the same function(s) as the delivery member 100.
  • These replacement strips 102 can be applied after each use of the instrument 1 or after repeated uses. Single or multiple strips can also be applied on a head surface to deliver multiple individual benefits or benefits that arise from the combined presence of multiple different strip actives. Such strips could be sold separately and applied by a user as desired. For the user's convenience, the replacement strips 102 could be carried within a recess or compartment in the handle 10 of the instrument 1.
  • Replacement/enhancement strips 102 that perform different functions within the mouth can also be provided.
  • the replacement/enhancement strips 102 can be designed to freshen breath, activate salivary glands, and/or desensitize teeth, etc.
  • these different functioning strips 102 can be applied to the instrument 1 in place of, or in addition to, the strips 102 that are regularly used on the head 20 to kill harmful bacteria within the mouth, for example.
