Abstract
A squeezable vessel contains a whitening compound and an elongated applicator tip extending outwardly from the vessel. A cap closed and seals the applicator tip, but may be removed under manual force. Once the cap is removed, the walls of the vessel may be squeezed together to urges the contents of the vessel to flow through a fluid passage through the elongated applicator tip to reach an accommodating surface. The accommodating surface may either be impregnated with a different material that reacts with the contents of the vessel upon contact or covers a chamber that in turn contains such a different material.
Description
DISPENSER AND APPLICATOR THAT BRING REACTIVE SUBSTANCES INTO CONTACT WITH EACH OTHER AT THE TIME OF USE
BACKGROUND-FIELD OF INVENTION
[0001] The present invention relates to a dispenser and an applicator that leaves two reactive substances separate until time of use. Such uses may include a tooth whitening or polishing system, a treatment for skin and other dermatologic applications, a delivery system for glues or other commercial compounds wherein the substrates are separate until delivery, pharmaceuticals, hemostatic agents, sealants and many other uses. With respect to tooth whitening or polishing in particular, one of the two substances may be hydrogen peroxide and/or carbamide peroxide that is isolated from the other of the two substances, such as sodium bicarbonate. The substances are subsequently mixed together at the time of use, for and during application of the mixture.
DESCRIPTION OF RELATED ART
[0002] Peroxide is the active ingredient in many tooth whitening products.
There are two types - carbamide peroxide and hydrogen peroxide - both work similarly. The peroxide breaks down, allowing oxygen into the enamel layer of the teeth, thereby bleaching them. Used properly and in safe concentrations, peroxide will not damage the enamel or any other part of teeth.
[0003] A mixture of hydrogen peroxide based whitening compounds with sodium bicarbonate produces notable effervescence in whitening if used immediately after mixing them together. As a result, the efficacy of hydrogen peroxide based whitening compounds is enhanced because of the mixing with the sodium bicarbonate.
_ l _
[0004] Teeth whitening systems contain different strengths of peroxide.
Those with higher concentrations of peroxide can produce faster, more dramatic whitening of teeth. However, there is an increased risk of creating temporary but uncomfortable tooth sensitivity with the higher concentration formulas. Products with a lower concentration of peroxide carry less risk of unpleasant side-effects, but they do not whiten as quickly as those with higher concentrations.
[0005] Some teeth whitening products are Ph buffered, to reduce the likelihood and severity of side effects. Carbamide peroxide is hydrogen peroxide combined with urea (an aqueous solution). Carbamide peroxide is found in professional tooth whitening formulas, teeth bleaching gels, light-activated tooth whitening gels and whitening toothpastes. Tooth whitening products containing carbamide peroxide typically range from concentrations of less than 10% to about 22%. Professional products may contain as much as 35%.
[0006] Hydrogen peroxide is found in whitening strips, paint on whiteners and whitening mouth rinses. A solution of about 10% carbamide peroxide is about as effective as a solution of 3% hydrogen peroxide. Similarly, a solution of about 22% carbamide peroxide is about as effective as a solution of 7.5% hydrogen peroxide.
[0007] Sodium bicarbonate (baking soda) helps clean teeth, freshen breath and neutralize mouth acids that can destroy tooth enamel. Used for decades for dental care, the FDA recognizes it as safe. It has been mixed conventionally with whitening compounds to whiten teeth.
[0008] Magnesium peroxide is recognized as an oxidizer that whitens teeth and aluminum oxide is recognized as a tooth surface polisher.
[0009] A need to improve conventional techniques for whitening teeth is discussed in US Patent No. 7,201 ,577, US Patent No. 6,929,475, US Patent No. 6,726,482 B2 and US Patent No. 7,070,413.
[0010] Various approaches have evolved for at-home teeth whitening procedures (without the need for the dental practitioner). Among the early at- home teeth whitening systems was a paste or gel containing a hydrogen peroxide or carbamide peroxide constituent. The gel or paste was applied to tooth surfaces by, for example, a toothbrush, a cotton swab, etc., as discussed in US Patent No. 7,070,413.
[0011] There are many well-known two-part substrates that, when combined or mixed, form a desired reaction. Such materials may be sealants, adhesives, hemostatic agents, whitening agents, and numerous other equivalent two-part materials that when combined form a material having desired properties, as discussed in US Patent No. 6,929,475.
[0012] US Patent No. 6,929,475 discloses a single use applicator of chemical or medicament material to be applied to a surface to be treated. The material, which may be a stable, inactive solid powder, is placed on an absorbent portion of the applicator. A liquid activating agent is released onto the absorbent portion of the applicator to activate the otherwise stable, inactive solid powder. The activated powder is applied to surfaces of the tooth with the applicator to whiten and polish the tooth. The absorbent portion may be a cotton swab.
[0013] Conventional dispensers that dispense contents from bottles and tubes trap significant amounts of their contents in corner regions. Users therefore, are generally unable to retrieve such trapped contents. Such dispensers may leak if not sealed securely.
[0014] It would be desirable to keep two reactants isolated from each other within a dispenser, yet allow them to blend together to form a blended mixture at the time of desired application of the blended mixture to the tooth being treated. It is further desired to apply the blended mixture to the treatment area of the tooth in a direct and even manner of application.
[0015] It is also desired to minimize an amount of the contents of the dispenser that cannot be retrieved by a user by preventing the contents from becoming trapped at corners of the dispenser. It is further desired to securely seal the dispenser to prevent leakage,
SUMMARY OF THE INVENTION
[0016] The present invention is directed to a tooth whitening and polishing system that does not require a professional, such as a dentist, to provide assistance or application.
[0017] The present invention comprises a dispenser that includes a squeezable vessel or fluid container, an applicator tip that defines a fluid passage, a compliant surface at a distal end of the applicator tip, and a cap that closes and seals the applicator tip. A compliant surface is a surface that is yielding or accommodating, as exemplified by foam. The contents of the squeezable vessel or fluid container may be urged out under manual pressure by squeezing together walls of a hollow body of the vessel or fluid container into a flattened condition from a non-flattened condition. The compliant surface may be porous and impregnated with a different material from the contents of the vessel or fluid container, or may cover a chamber that contains such a different material. The applicator tip is elongated to define a length sufficient to reach even deep and hard to reach tooth surfaces to be treated.
[0018] As an example, the contents of the vessel or fluid container may be a whitening compound gel whose active ingredient includes hydrogen peroxide or carbamide peroxide. The different material that impregnates the porous compliant surface may be a solid powder such as sodium bicarbonate or baking soda. The porous, compliant surface may be sponge-like. The sodium bicarbonate or baking soda may be in cake form if the porous compliant surface covers a chamber that contains the different material.
[0019] When a user squeezes the vessel, its content (e.g., tooth whitening compound gel) passes through (is urged through) the fluid passage to reach the compliant surface where it mixes or blends with the solid powder to preferably produce foam. The foam is applied to the teeth by pressing the compliant surface against the areas of the teeth to be treated and scrubbing same to whiten the teeth.

[0060] An applicator tip 26 is elongated to terminate at a distal end where there is a porous and compliant surface 40, which may be of a foam or sponge material. The compliant surface 40 is used to evenly apply the whitening
compound 44 (FIG. 3) to the tooth surfaces being treated and can additionally be used to gently scrub the tooth surface.
[0061] In FIG. 3, a stopper 12 passes through the porous and compliant surface 40 to seal a fluid passage 32 that projects outwardly from a body of the vessel or fluid container 20. A sealing bead 18 provides an annular type seal with the cap 10 to prevent leakage of the contents of the vessel or fluid container 20.
[0062] Turning to FIG. 4, the vessel or fluid container 20 may be squeezed in the direction indicated by arrows F, although such squeezing may occur at other areas and does not require pressure from two opposite sides or areas; pressure on one side or area may also be sufficient. A whitening compound 44 (or, for other applications, the corresponding compound) is urged through the fluid passage 32 and through the passage 48 of the applicator tip 26, where the whitening compound 44 mixes with sodium bicarbonate, producing a reactant 46 that becomes accessible on the porous and compliant surface 40.
[0063] Referring to FIG. 5, it can be seen that the vessel or fluid container
20 is able to flatten under manual squeezing pressure, allowing almost all of the contents to be expelled from the interior volume 50. The sides 56 conform closely to the contours of bulkhead 52. There are lugs 38 that act to further force remaining fluid from the vessel interior 50.
[0064] FIG. 6 shows a bulkhead 52 attaching applicator tip 26 to fluid container sides 56, having a wedge shape, allowing said sides 56 to drape.
[0065] Turning to FIGS. 7 and 8, opposite end views of the vessel or fluid container 20 with applicator tip 26 are depicted. Sides 56 (FIG. 6) come to a sharp seam without sidewalls, allowing them to collapse flat.
[0066] Turning to FIG. 9, an angle of inclination B of the compliant surface
40 is preferably within a range of 30° to 45° for optimal application of the activated reactants on the compliant surface 40. That is, the reactants become active by squeezing on the surface, thereby causing the whitening compound contents (e.g., hydrogen peroxide or other contents for other applications) to move within the vessel or fluid container 20 through the applicator tip 26 and to deposit onto the impregnated absorbent, compliant surface 40 (impregnated with sodium bicarbonate, baking soda or other substrates for other applications).
[0067] If desired, additional ingredients may be added, such as ingredients suited to polish teeth, for added benefit.
[0068] Turning to FIGS. 10 and 12, a further embodiment of a dispenser is depicted that includes a vessel 60 that has an integrally formed rigid substructure 62. Turning to FIGS. 11 and 13, a dispenser 70 is shown that includes the vessel 60 of FIGS. 10 and 12 and includes a contoured, soft, elastomeric application tip 72 that is fitted over or with the rigid substructure 62. The contoured, soft, elastomeric application tip 72 allows for squeegee like, even spreading of the gel over the tooth surfaces and its softness helps prevent injury to the gums or teeth (or skin, etc. for other applications) that is more apt to occur with harder material.
[0069] The rigid substructure 62 may be elongated with a central tube 64 that extends in a direction of elongation of the rigid substructure 62. On both sides may be formed a series of spaced apart channels 66 that likewise extend in a direction of elongation of the rigid substructure 62 substantially parallel to each other.
[0070] Turning to FIGS. 13-20, the structure of the vessel 60 can be seen in greater detail. The rigid structure 62 preferably widens toward the central tube 64 from the opposite ends to define an elliptical outline broken by the spaced apart channels 66 (see FlG. 19). Turning to FIGS. 21-27, the structure of the contoured, soft, elastomeric application tip 72 can be seen in greater detail. The
contoured, soft, elastomeric application tip 72 includes a recess 74 at one end and a slot 76 that spaces two symmetric legs 78 apart from each other. The shape of the contoured, soft, elastomeric application tip 72 may be such that it diverges outwardly from the recess 74 to a location near the recess and then converges or tapers along the symmetric legs 78 until termination. The symmetric legs may each have grooves 79 spaced apart from each other. FIGS. 28-33 show the dispenser 70 in greater detail when closed by a cap 80. The cap 80 may be formed with structures that complement the symmetric legs 78 and slot 76 so as to engage and seal off the dispenser 70.
[0071] Referring to FIGS. 34-35, a preferred embodiment is depicted for attaching a bicarbonate of soda treated sponge foam pad 90 to the tip 100. The sponge foam pad 90 is formed of a die cut open cell foam rubber that has been dipped in a solution of bicarbonate of soda and allowed to dry. This treated sponge foam pad 90 is then attached to a recess 112 at an end of the tip 100 with adhesive or heat sealing. The sponge foam pad 90 holds a quantity of treated gel at the tip 100 during application without having the gel drain or slide off. This allows for thicker, more even coating.
[0072J Alternately, as seen in FIG. 36, the tip 100 can have additional ribbing in the form of tabletized inserts 120, which captures powdered or tabularized bicarbonate of soda. The tabletized inserts 120 are fitted into complementary-shaped channels 122 in the end of the tip 100.
[0073] Alternatively, treated blotter paper material 130 (see FIG. 37) can replace the sponge material of the sponge foam pad 90 of FIGS. 34-35 at the tip 100. This provides a means of capturing larger amounts of powder in the grooves of the tip by sealing to the perimeter, thereby forming a cover.
[0074] FIGS. 38-40 show a progression of views for filling the dispenser 70 with contents to be dispensed. Initially, the dispenser 70 and cap 80 are formed separately, with the dispenser 70 being open at opposite ends. One of the open
ends is closed and sealed by cap 80. Thus, the assembly is ready to be filled as in FIG. 38. After filling the dispenser through the open end with contents to be dispensed, the opening is closed by heat sealing inwardly from the periphery (within heat seal area 130) in the manner of FIG. 39. The portion of the dispenser between the heat seal and the periphery may be trimmed off (trim area 132) to yield the finished product of FIG. 40.
[0075] As stated above, the applicator of the present invention may be used other than for teeth whitening or polishing. For instance, the following applications are contemplated: dermatological applications by delivering skin treatment applications; adhesives, such as epoxies, sealants, pharmaceutical treatments, remedies and drugs; naturopathic applications; and many others.
[0076] While the foregoing description and drawings represent the preferred embodiments of the present invention, it will be understood that various changes and modifications may be made without departing from the spirit and scope of the present invention.
