## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This disclosure claims the benefit of U.S. Provisional Application No. 61/823,348 filed on May 14, 2013 which is hereby incorporated by reference.


TECHNICAL FIELD
This disclosure is related to the dispensing of tablets, specifically the cleaning of dentures.
BACKGROUND
The statements in this section merely provide background information related to the present disclosure. Accordingly, such statements are not intended to constitute an admission of prior art.
Dentures, when worn daily, can pick up stains, especially if the wearer smokes or drinks a lot of tea, coffee or red wine. In most cases this staining is removable with regular cleaning. A common practice is to use an effervescent (fizzy) denture cleaner that is provided in tablet form. Denture cleaning tablets presently come in individually wrapped packaging where the consumer must squeeze the packaging and push the tablet through paper/foil to drop it into a cup. For older customers or customers with arthritis, such a routine can be difficult or painful, and some are physically unable to do so and must enlist the help of others. This individual foil/blister packaging is also wasteful and expensive, creating excessive waste that the consumer must then throw away.
SUMMARY
A dispenser can be utilized for selectively providing a denture cleaning tablet. The apparatus includes a rotatable storage container holding a plurality of columns of the tablets and a dispensing mechanism. The dispensing mechanism includes an input hole. A user of the dispenser can acquire a tablet through rotating the rotatable storage container to align one of the columns of tablets to the input hole and cycling the dispensing mechanism.

DETAILED DESCRIPTION
Referring now to the drawings, wherein the showings are for the purpose of illustrating certain exemplary embodiments only and not for the purpose of limiting the same, tablets are used for cleaning a denture. The tablet is acquired for the shipping packaging and dropped in water, wherein the chemicals in the tablet are activated and act to clean dentures dropped in the water. Packaging used for dentures can be difficult to open. In particular, a user with symptoms of age and/or arthritis can have difficulty opening individually wrapped tablets. An apparatus is provided that permits a column of tablets or several columns of tablets to be loaded into a dispenser and selectively provided through simple movements of the user's hand or of a cycling of a control tab.
FIG. 1 illustrates a dispensing device including a cylindrical storage container attached to a dispensing base. Storage container 10 holds in an organized fashion a product that is to be discreetly dispensed to a user. In one exemplary embodiment, the product to be dispensed includes denture cleaning tablets 8. In another embodiment, a granular denture cleaning product can be discreetly dispensed. While tablets 8 are illustrated in use throughout the application, it will be appreciated that very similar configurations can be used to discreetly cup and then dispense a granular product.
On the bottom of dispensing base 20, slot 22 is sized to permit a round tablet 8 to freely slide from within base 20 to outside the base. Slot 25 permits a user to slide a finger under slot 22 and manually move a tablet from an interior portion of base 20 to outside of base 20. A column of aligned tablets 8 can be stored within storage container 10, such that a tablet 8 on the bottom of the column of tablets is exposed to slot 22 and presented to the user for manual movement. As the bottom tablet 8 is removed, a next tablet 8 in the column falls to slot 22, such that it is present the next time the user needs a tablet. Tablet 8, once removed, can be placed in glass 30 filled with water 35 for use in denture cleaning known in the art.
Storage container 10 can be refillable. FIG. 2 illustrates storage container 10 removed from base 20 and flipped over. The interior of exemplary storage container 10 includes four cavities 62 which can be filled with columns of tablets 8. Two of the exemplary cavities 62 are illustrated filled, and two of the exemplary cavities 62 are illustrated unfilled.
Base 20 is illustrated including slot 22 and base surface 28 upon which, when storage container 10 is installed to base 20, storage container 10 rests. Base surface 28 includes an exemplary hole through which a tablet, when a column of tablets is aligned with the hole, can fall and be presented within slot 22 for manual movement by the user.
In one embodiment, storage container 10 snaps into and can rotate within base 20. Rotation of storage container 10 within base 20 permits a plurality of columns of tablets 8 to be aligned with the hole in base surface 28, such that each of the columns can be systematically used until the entire storage container is emptied. Each of the columns can be located at an equal radius from a center of the storage container 10, such that each of the columns can be placed in line with the hole in base surface 28. Details 40 and 42 illustrate matching tongue and groove details that enable a snapping function of storage container 10 into base 20, such that container 10 and base 20 are unified as a durable dispenser until the user pulls the container 10 from base 20. In order to install container 10 to base 20, one exemplary method is to fill container 20 in an upside down orientation, as illustrated in FIG. 2, install base 20 to container 10 while upside down, and then flip dispenser 5 into an upright position.

FIG. 12 illustrates an exemplary alternative embodiment of a base for use with a dispenser, wherein a base section includes a slot permitting a tabbed rotating plate to be situated within the base section. Base 720 includes base section 730 and tabbed flat plate 740. Base section 730 is configured to receive a storage container and includes a tongue and groove feature 732. Tabbed flat plate 740 fits within base section 730 and tab 744 of plate 740 fits through slot 734 of base section 730. Plate 740 includes hole 742 configured to receive a tablet as disclosed herein. As tab 744 is moved, a tablet can be fed to hole 736 in base section 730, permitting the tablet to fall through hole 736.
FIG. 13 illustrates an exemplary dispenser configured as a wall mounted dispenser configured for easy access to a disabled user. Base 720 of FIG. 12 is assembled to a storage container 710 and a wall bracket 750. Tab 744 can be easily cycled, for example, by a user with arthritis or other physical disability by simply pushing on the tab, thereby causing tablet 8 to be dropped from the dispenser.
FIG. 14 illustrates in schematic assembly view an exemplary dispenser including an easy install cartridge and a wall mount permitting rotation of a cylindrical storage container. Dispenser 800 is illustrated including cylindrical storage container 810, container base plate 820, and dispenser base plate 850. Stage container 810 and container base plate 820 rotatably connect together and create a cavity therebetween to store a plurality of columns of tablets 805. In the exemplary embodiment of FIG. 14, tablets are provided in a disposable easy install cartridge 860. Cartridge 860 includes a plurality of tube sections 870 and a flat base section 872. Cartridge 860 is installed to the inner portion of storage container 810, and container 810 is then installed to plate 820, such that flat base section 872 is resting upon the flat surface of plate 820. Container 810 is keyed to cartridge 860, such that the two turn in unison, and container 810 when turned lines up any of the four tube sections with hole 822 of plate 820. In this way, tablets within cartridge 860 can be aligned and provided within dispenser 800. In one embodiment, the flat section of container base plate 820 is relatively thin and hole 822 can include generously radiused or angled corners, such that a column of tablets sitting within a tube section 870 of cartridge 860 passing over hole 822 will easily be able to be rotated past the hole, with the tablets falling into hole 822 and being eased out of hole 822 by the rotating motion of cartridge 860 and container 810 relative to container base plate 820.
Starting with a depleted cartridge 860 within dispenser 800, installation of a new cartridge 860 to container 810 will typically include removing container 810 from plate 820 and flipping over container 810. The depleted cartridge 860 is removed and the new cartridge 860 is installed. The remainder of dispenser 800, including plate 820 and 850 encasing plates 830 and 840, can be described as an actuable cyclic tablet dispensing mechanism. Hole 822, which is selectively aligned to one a plurality of tablet columns stored in storage container 810, can be termed an input hole for the dispensing mechanism. The actuable cyclic tablet dispensing mechanism is flipped and installed to the flipped container 810 including the new cartridge 860 to recreate the dispenser 800. Dispenser 800 can then be flipped back to upright and installed to wall bracket 890.
Container base plate 820 and dispenser base plate 850 connect together and create a cavity therebetween to house a stationary bottom plate 840 and a rotating dispenser plate 830 to create a spring loaded mechanism for selectively presenting a hole for 832 for a tablet to drop into in order to be dispensed from dispenser 800, the assembly of plates being termed as an actuable cyclic tablet dispensing mechanism or a dispensing mechanism. Stationary bottom plate 840, as illustrated, includes an integrated spring feature 844 which is connected to dispenser plate 830. Dispenser plate 830 includes a tab which can be actuated to rotate dispenser plate 830 relative to plates 820, 840, and 850, which remain stationary. Through the rotation of dispenser plate 830, hole 832 is selectively aligned with hole 822 of plate 820, such that a tablet 805 can fall into hole 832. Because hole 820 and hole 842 of stationary bottom plate 840 are offset, a tablet falling into hole 832 when holes 832 and 822 are aligned will not fall out of the dispenser. Such an alignment of hole 822 and 842 would cause an entire column of tablets to immediately fall out of the dispenser. Instead, dispenser plate 830 has a thickness selected such that a single tablet 805 can fit within hole 832 and rest upon a flat surface of plate 840, and as dispenser plate 830 is rotated into alignment with hole 842, the single tablet can fall out of the dispenser. Dispenser base plate 850 includes hole 852 aligned with hole 842.
Denture tablets include chemicals that react to water. A column or set of tablets can be ruined by exposing them prematurely to water. In one exemplary embodiment, an o-ring 880 or a plurality of o-rings can be used to make dispenser 800 resistant to water intrusion. Such an o-ring can be used in a number of locations within the dispenser to seal one surface against another surface, for example, with the o-ring 880 being held in a circular channel, with a small portion of o-ring 880 extending above a surface of the part and connecting with a neighboring part, such that the o-ring is elastically deformed and creates a sealing contact with the neighboring part. In the illustrated exemplary embodiment of FIG. 14, a ring-shaped channel can be formed around hole 822 on a bottom surface of container base plate 820, such that the o-ring 880 causes the container plate to seal against the flat surface of a top side of dispenser base plate 830. In an alternative embodiment, a ring-shaped channel can be formed around hole 832 on a top surface of dispenser base plate 830, such that the o-ring 880 causes the dispenser plate to seal against the flat surface of a bottom side of container base plate 820. In this way, the cavity formed between container 810 and plate 820 containing cartridge 860 can be sealed, and moisture and humidity can be prevented from causing damage to the tablets within.
Plate 830 includes center hole 834, which accepts a post or rivet which permits the plate 830 to turn relative to plates 820, 840, and 850. In the exemplary embodiment of FIG. 14, plate 820, 840, and 850 also include center holes in alignment with hole 834, although in other embodiments, either plate 820 or 840 could project a post to extend through hole 834.
Wall bracket 890 is illustrated as a mechanism to securely mount dispenser 800 to a wall. Bracket 890 includes arm 892 configured to rotatingly connect to protruding feature 812 on top of container 810. Bracket 890 further includes base holding section 894 configured to accept dispenser base plate 850. According to one embodiment, in order to permit easy removal of dispenser 800 from bracket 890 so that the dispenser can be flipped over for refill, plate 850 and the holding section 894 can each include mating features that permit the dispenser 800 to be easily lifted out of holding section 894 but that prevent plate 850 from turning relative to holding section 894. With plate 850 and the rest of the dispensing mechanism (including plates 820, 830, and 840) held still, and with arm 892 permitting container section 810 to rotate relative to bracket 890, a user can selectively align one of the plurality of tablet columns within the container section 810 to the hole 822 in plate 820 such that the dispenser 800 can operate.
FIG. 15 illustrates the exemplary dispenser plate of FIG. 14 including a spring feature receiving slot. Dispenser plate 830 is illustrated including tab 836, hole 830, and center hole 834. Dispenser plate 830 is illustrated flipped over, such that a bottom side 831 is visible. Spring feature receiving slot 838 is illustrated, ready to receive a post from a spring feature located on neighboring stationary bottom plate 840.
FIG. 16 illustrates the exemplary stationary bottom plate of FIG. 14 including an integrated spring feature. Stationary bottom plate 840 is illustrated including hole 842, center hole 841, and spring feature 844 including spring feature post 846. Exemplary spring feature 844 is illustrated as an arm configured to bend an apply a spring force or torsion to dispenser plate 830 as it is turned, causing plate 830 to return to an original position as force is removed from tab 836. Spring feature 844 can utilize elastic deformation of the material of plate 840 made of ABS plastic or polypropylene to provide the spring force. The spring feature can be configured to accept or be molded with a piece of spring steel therewithin to provide repeatable and reliable spring force. Bottom plate 840 can alternatively be configured to receive a spring feature entirely made up of spring steel, such that features of plate 840 act as a holding feature for the ancillary spring feature. In another embodiment, plate 840 can be constructed of a thin piece of spring steel, with post 846 being riveted in place. Bottom plate 840 includes exemplary securing feature 849 which secures to a matching feature on dispenser base plate 850 to prevent plate 840 from turning relative to plates 850 and 820. One will appreciate that, in the alternative, the spring feature could be located on the dispenser plate and the slot interacting with the spring feature can be located on the stationary bottom plate. Spring feature 844 is illustrated as an exemplary arm connected to the rest of the stationary bottom plate 840, with the spring force being supplied by flexing the arm from its original orientation and elastic forces in the arm causing the arm to provide a force to return to its original orientation. One will appreciated that other springs and spring mechanisms, for example utilizing coil springs or a pair of spring steel levers could be used to provide the spring force, and the disclosure is not intended to be limited to the examples provided herein.
One will further appreciate that the stationary bottom plate need not be a separate piece from the dispenser base plate or the container base plate, with one of the spring feature or the slot being located on one of the dispenser base plate or the container base plate, and with the mating spring feature or slot being located upon the dispenser plate. In such a configuration, one could say that the stationary bottom plate is formed unitarily with the dispenser base plate or formed unitarily with the container base plate.
FIG. 17 illustrates the container base plate of FIG. 14 in detail including an exemplary o-ring channel that can make the dispenser resistant to water intrusion. Plate 820 includes hole 822 and o-ring channel 826 configured around hole 822 on bottom surface 824 of plate 820. Bottom surface 824 abuts the flat top surface of dispenser plate 830 when the two are assembled into the dispensing mechanism. When o-ring 880 is installed to o-ring channel 826, the o-ring seals to the flat surface of plate 830, thereby preventing moisture and humidity from entering the cavity formed by container 810 and plate 820.
FIG. 18 illustrates an exemplary cartridge of FIG. 14. Cartridge 860 includes a plurality of tube sections 870, each configured to hold a column of tablets. Tube sections 870 are each attached or formed unitarily with flat section 872 which is configured to rest upon a top flat section of plate 820. Cartridge 860 can be refillable. Cartridge 860 can be disposable (and made of recyclable material.) In the embodiment of FIG. 18, a foil seal 876 is illustrated removed from a open side 874 of cartridge 860. The cartridge can be manufactured according to a number of methods, for example, by injection molding, blow molding/vacuum forming, and by attaching (e.g. gluing, sonic welding, or any similar process known in the art) a plurality of tube sections to a carrier piece forming flat section 872. In one embodiment, the tub sections can be a thin film, capable of being easily crushed when the tablets are removed or depleted.
Dispensers as disclosed herein can be constructed of any of a number of materials including plastic materials known in the art and approved for use in household medical devices.
A number of different dispenser embodiments are disclosed herein. A number of different embodiments and configurations of features are envisioned for use with the provided examples, and the disclosure is not intended to be limited to the specific examples provided herein.
