A typical bead dispenser includes a plunger housed in a chamber that has a lower exit opening that is horizontally misaligned relative to an upper feed hole into the chamber. The plunger has a receptacle hole for receiving a bead that is aligned with the upper feed hole in a non-actuated position of the plunger. A manual actuation of the plunger horizontally displaces the plunger within the chamber such that a bead carried in the plunger receptacle hole is carried to and over the lower exit opening in the chamber whereby the bead can drop out of the dispenser device.
A conventional pill dispenser includes a threaded neck and a central funnel portion by which pills can be directed to an opening. At the bottom of the opening is a slide having a stop portion which prevents the pills from being discharged from the pill dispenser. When the slide is depressed, the stop is moved and the pill is discharged from the opening. However, as one of ordinary skill in the art would know, the funnel may become blocked or bridged by several pills.
Another conventional pill dispenser includes a dispenser mechanism having a sliding plate disposed between a reservoir and a base plate. The sliding plate, reservoir and base plate all have corresponding holes therein, and the sliding plate is biased by a spring. When the sliding plate is moved, all of the holes between the sliding plate, reservoir and base are aligned within one another so as to allow several pills to be simultaneously discharged from the dispenser. However, it appears that the pills may block the holes of the sliding plate such that the pills cannot be properly dispensed therefrom.
Moreover, many prior art devices require complex mechanizations, the use of two hands and/or a manual strength to dispense the beads. This can be particularly difficult for the elderly, infirm, or handicapped individuals who cannot assert the necessary pressure.
Accordingly, there is a need for a bead dispensing device that is capable of ensuring that beads do not block or otherwise bridge a bead receiving channel, which would otherwise result in a flawed bead distribution, and can be operated single-handedly with a slight amount of pressure.
Disclosed herein is an apparatus for dispensing beads that enables a user to quickly fill and dispense beads effortlessly.
In one embodiment of the present disclosure, the apparatus for storing and dispensing items includes a loading chamber situated at an upper end of a housing of the apparatus and used for storing the items to be dispensed, a turn table located in the loading chamber and on which the loaded items are kept for dispensing, wherein the turn table includes a central opening and a plurality of protrusions that enable an agitation and a guidance of the loaded items towards the central opening during a spinning of the turn table, and a wheel rotationally mounted in the housing near a lower end of the housing, wherein the wheel includes a cavity formed at a circumferential edge of the wheel for storing one of the items received from the turn table through a transition channel, and wherein the wheel includes a shaft that extends centrally in opposite directions from each side of the wheel. The apparatus further includes an actuator for manually triggering a vertical rotation of the wheel so as to move the cavity from a first alignment position with the transition channel to a second alignment position with a dispensing hole to dispense there through one of the items stored in the cavity, and for triggering the spinning of the turn table to agitate and dispense the loaded items through the central opening.
In an additional embodiment, the turn table includes a hollow cylindrical protrusion extending from a bottom surface and having vertical teeth extending radially and outwardly, wherein the shaft includes a cylindrical protrusion having horizontal teeth extending radially and outwardly, and wherein the actuator includes a vertical body having at an upper end a set of vertical teeth facing sideways and configured to engage with the vertical teeth of the turn table teeth, and at a lower end a set of horizontal teeth facing downwards and configured to engage with the horizontal teeth of the wheel.
In an additional embodiment, the apparatus further includes a tube element that fits within the central opening, wherein the tube element includes a top part that includes two diametrically opposed openings formed by two vertical walls and a cover that is connected to top ends of the two vertical walls.
In yet another embodiment, the transition channel is configured to provide a pathway for the beads between the central opening of the turn table and the cavity of the wheel, and is shaped as a cylindrical tube that is sized and shaped to contain a single line of beads.

As shown in
As shown, in one exemplary embodiment bead dispensing device 100 includes a cap 116 that defines internally loading chamber 102. Cap 116 includes a cap opening 118 through which the beads can be loaded. The beads can be loaded by scooping bead dispensing device 100 into a container of beads, holding cap opening 118 under a bulk dispensing device or funnel, and the like.
As shown, cap 116 may engage a top end of the main body of bead dispensing device 100 by screwing on, snapping on, utilizing a friction fit and the like. Cap 116 may include a rotatable cover 120 to seal/close cap opening 118, thereby preventing the loaded beads from spilling out. Alternatively, cap 118 may be sealed or closed by a slidable flap, a hinged flap, and the like. In one embodiment, bead dispensing device 100 may not have a cap, leaving the main body with an uncovered loading end 101 thereby permitting a loading and unloading of beads at any time without opening or removing a cap.
Now referring to FIGS. 3 and 4A-4B, turn table 104 is configured to have a slightly slanted top surface 401 from a circumference to a central opening 402 to facilitate the feeding/sliding of the beads into openings 109 of tube 108, which is configured to fit within central opening 402. Turn table 104 further includes a plurality of angularly distributed protrusions 404, each of which may have a triangular shape with angled sides oriented towards the center of turn table 104, thereby enhancing a sliding movement of the beads towards tube 108 during agitation of the beads generated by a spinning of turn table 104. Moreover, turn table 104 includes a plurality of radial protrusions 406 that also angularly distributed, each of which is positioned between two adjacent triangular protrusions 404. Alternatively, turn table 104 may include a plurality of angularly distributed radial grooves that have a narrowing shape from the outside circumference of turn table 104 to central opening 401 when getting closer to tube 108.
As shown in
Turn table 104 can be placed on the top end of bead dispensing device 100, when cap 116 is not affixed to it, where it is rotationally supported by an internal circular flange or ridges. Turn table 104 and the device's circular flange may be made of a plastic having low friction properties, thereby permitting turn table 104 to spin easily within loading chamber 102.

Now referring to
As shown, shaft 604 includes a multitude of circular flanges 606, each of which is located at one of its opposite ends. Shaft 604 further includes a cylindrical protrusion 608 formed with a circumferentially serrated external surface that forms extension teeth 610, hereafter referred to as dispensing wheel teeth 610.
To enable a rotation of dispensing wheel 112, dispensing device 100 includes a pair of bearings formed on its internal walls and on which opposite ends of shaft 604 can be mounted. In one embodiment, the bearings may be cylindrical to rotationally accept there within the ends of shaft 604. Alternatively, the bearings may be semicircular with grooves in which circular flanges 606 can be rotationally supported.
Now referring to
As stated above, bead dispensing device 100 includes transition channel 110 positioned in a middle portion between a lower end of tube 108 and an opening of cavity 114 of dispending wheel 112, in which the beads can be arranged in a vertical line. As such, transition channel 110 provides a pathway for loading and storing beads in a particular orientation in order to provide an accurate and efficient dispensing of the beads. Transition channel 110 is preferably a cylindrical tube that is sized and shaped to contain a single line of beads having the same orientation. Alternatively, any other suitable size and shape may be used for transition channel 110.
During operation, the user will hold bead dispensing device 100 in one hand and remove or open cap 116. The user will then scoop bead dispensing device 100 into a container of beads, filling loading chamber 102 with a desired amount of beads. Once loading chamber 102 is loaded with a desirable amount of beads, the user will replace or close cap 116. To dispense the beads, the user holds dispensing end 103 of bead dispensing device 100 over a desired surface, such as a previously placed glue area, and presses push button 106 from a resting position, as shown in
When pressed by the user, push button 106 presses via notch 716 the above-discussed spring, which pushes back/biases push button 106 to its resting position after the user stops pressing push button 106. Then when push button 106 is biased back to its resting position, transition channel 110 is aligned again with cavity 114 thereby enabling a loading of another bead into cavity 114 if there was at least one bead in transition channel 110, thereby enabling a shift down by one bead length of the beads still in transition channel 110.
Moreover, during operation, when push button 106 is pressed into dispensing device 100 turn table 104 is configured to spin clockwise or counterclockwise horizontally, and dispensing wheel 112 is configured to spin vertically about 180 degrees to line up the opening of cavity 114 with an upper end of dispensing hole 113 to dispense a bead stored in cavity 114.
During the returning movement of push button 106 to its resting position, turn table 104 is configured to spin backward in a counterclockwise or clockwise manner, thereby agitating again beads remaining thereon to feed at least one of them into transition channel 112, and dispensing wheel 112 is also configured to spin backward to line up the opening of cavity 114 with the bottom end of transition channel 110.
In one exemplary embodiment, a series of partial pressings of push button 106 can enable a continuous filling of transition channel 110 without any dispensing of beads via dispensing wheel 112 because each partial pressing does not enable a line-up of cavity 114 with dispensing hole 113.
In an alternate exemplary embodiment of the present disclosure, in order to dispense more than one bead (for example three beads) during a single full pressing of push button 106, dispensing wheel 112 may include three cavities distributed within a particular arc along its circumference. Push button 106 is configured to have a longer sliding length within dispensing device 100 when pressed by the user and a wider teethed lower end so as to rotate dispensing wheel 112 more than 180 degrees when fully pressed by the user, thereby enabling a sequential alignment of the three cavities with dispensing hole 113. Moreover, the user may be able to release only one bead by pressing push button 106 into dispensing device 100 for a first length that is equal to about one third of its longer sliding length, or two beads by pressing push button 106 for a second length that is equal to about two thirds of its longer sliding length.
While the present disclosure has been described in terms of exemplary embodiments, those skilled in the art will recognize that the present disclosure can be practiced with modifications in the spirit and scope of the appended claims. For example, dispensing of the beads may be gravity based, spring based and the like. These examples given above are merely illustrative and are not meant to be an exhaustive list of all possible designs, embodiments, applications or modifications of the present disclosure.
A person of ordinary skill in the art would appreciate the features of the individual embodiments, and the possible combinations and variations of the components. A person of ordinary skill in the art would further appreciate that any of the examples could be provided in any combination with the other examples disclosed herein. Additionally, the terms “first,” “second,” “third,” and “fourth” as used herein are intended for illustrative purposes only and do not limit the embodiments in any way. Further, the term “plurality” as used herein indicates any number greater than one, either disjunctively or conjunctively, as necessary, up to an infinite number. Additionally, the word “including” as used herein is utilized in an open-ended manner.
