BACKGROUND OF THE INVENTION
[0002] Beads and other small objects, whether circular or irregular in shape, are commonly used in arts and craft activities for both adults and children. Plastic, wooden, glass or metal beads are used in making jewellery or decorating articles including clothing and other fabrics. In a non-decorative sense beads, such as ball bearings, are used in machinery and other mechanical devices.
[0003] Polyvinyl acetate (PVA) in the form of solid round beads are also known to be used in children's artwork activities whereby beads are arranged by colour on a template to produce a pattern, picture or the like. Water is then sprayed onto the template to dissolve the beads and allow them to run into one another and create blocks of colour separated by partitions in the template and thereby create a picture.
[0004] The problem with using beads and bead like objects, is that given their small size and often spherical nature they are difficult to handle and awkward to place and hold in position. This has brought about the present invention which addresses the difficulty in handling beads.
SUMMARY OF THE INVENTION
[0005] In accordance with the present invention there is provided a bead dispenser comprising:
an elongated housing in which beads are held in at least two separated bead columns, and a dispensing nozzle at one end of the elongated housing through which beads are dispensed; and
a dispensing mechanism to dispense beads from a bead column, whereby one of the bead columns is selected from which to dispense a bead through the dispensing nozzle.
[0006] Preferably, the bead dispenser dispenses at least two types of beads. In a preferred embodiment the bead dispenser includes four bead columns, and in another embodiment the dispenser may comprise six or more bead columns. The bead columns in the preferred embodiment are in the form of extruded or moulded plastic tubes that may be held in position in the housing by gluing and/or retaining the tubes by moulded partitions inside the housing.
[0007] The housing preferably comprises two co-axial components:
a dispensing casing which houses the dispensing mechanism; and a storage casing which holds the beads. The storage casing and dispensing casing are rotatable relative to one another such that one casing may be twisted relative to the other casing about a common axis. This is to align one bead column with the dispensing mechanism thereby allowing beads to be individually dispensed from that selected column.
[0008] The storage casing and dispensing casing are preferably held in locked engagement in the axial direction but are permitted to relatively rotate around the common axis. Preferably, the casings are rotatable over location points which urge the casings to stop rotating at the location points whereby each location point corresponds with a bead column. The location points are preferably defined by a node and recess engagement between the storage casing and dispensing casing.
[0009] The beads are preferably arranged in a single file within each bead column. The beads are typically of different colours and similar sizes.
[0010] The dispensing mechanism is preferably a biased mechanism including a moveable body having a cavity through which a bead is adapted to pass from an inlet to an outlet. A trigger associated with the dispensing mechanism is activated to align the inlet with a bead column to allow a bead in that column to enter the body. Releasing the trigger moves the dispensing mechanism body out of alignment with a bead column and into a position whereby the outlet is aligned with the dispensing nozzle to allow a bead in the dispensing mechanism to dispense through the nozzle.
[0011] A spring is preferably located between the body of the dispensing mechanism and the interior of the dispensing casing.
[0012] The storage casing preferably includes a moveable lid to allow for access for filling the storage casing with beads. The lid is preferably funnel shaped and contains a central hole through which a bead can pass. The lid is shaped to hold an amount of beads that is substantially equal to the number of beads required to fill a bead column.
[0013] The bead dispenser also preferably includes a removal tool for picking up a bead. The tool includes a stem and a portion of adhesive material on the end of the stem whereby the stem can be inserted into the hole of the lid. The adhesive material is preferably thermoplastic rubber (TPR).

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0015] Illustrated in the drawings is a bead dispenser 10 for dispensing beads 12 from an interior of the bead dispenser 10. The bead dispenser provides a useful and manageable means for handling beads in a controlled manner. In the preferred embodiment shown the bead dispenser is used for dispensing beads used in arts and crafts, and more particularly dissolvable PVA beads.
[0016] The bead dispenser 10 comprises an elongated housing 14 wherein the housing 14 consists of an upper storage casing 16 co-axially connected to a lower dispensing casing 18. The beads 12 are stored in the storage casing 16 and are adapted to enter the dispensing casing through a dispensing mechanism 20 and to exit the bead dispenser 10 through a dispensing nozzle 15 located at a lower end of the dispenser 10. The storage casing 16 is elongated and adapted to hold at least two separated bead columns 30.
[0017] The storage casing 16 and dispensing casing 18 extend coaxially along a common axis 50. They are held in locked engagement in the axial direction and are rotatably engaged such that the casings are rotatable relative to each other about axis 50. The rotational relationship between the storage casing 16 and dispensing casing 18 allows one casing to be twisted relative to the other about the common axis so as to align a selected bead column 30 with dispensing mechanism 20 and allow a bead from that column to be dispensed.
[0018] Location points between the storage and dispensing casings urge the casings to stop rotating at the location points. The location points are aligned with each bead column and define correct alignment of each bead column with the dispensing mechanism 20 such that bead dispensing can occur.
[0019] The interaction between the location points and bead column is defined by a node and recess type engagement. Specifically, the storage casing 16 is provided with either a node or recess and the dispensing casing 18 is provided with corresponding recesses or nodes. Typically, and as shown in the drawings and in particular Figure 3, a node 42 on the storage casing engages with a recess 44 provided on the dispensing casing. A recess 44 is provided with each bead column such that as the casings are rotated the node 42 will engage with a recess 44 corresponding to a bead column 30 and the user is made aware when a bead column is correctly aligned. The location points also hold the bead column correctly aligned during use. A further twisting force overcomes the node and recess engagement to allow the casings to rotate past a location point to the next location point.
[0020] Because the housing 14 includes at least two separated bead columns 30 the bead dispenser is capable of dispensing at least two types of beads, and usually similar shaped beads of different colours. In the preferred embodiment illustrated in the drawings the dispenser includes four bead columns 30 whereby four different beads may be dispensed. It is understood that larger versions of the bead dispenser may hold more than four bead columns, such as six bead columns.
[0021] The bead columns are in the form of extruded or moulded plastic tubes 32 which are filled with beads 12. Tubes 32 are typically glued in position inside the storage casing 16 and may be further held in position in a separated manner from the other tubes by moulded partitions 34 inside the storage casing 16. Partitions 34 have the effect of retaining tubes 32 in position before the glue used to position the tubes has set or if glue is not used.
[0022] It is understood that the bead columns may not be in the form of tubes but may simply be defined by the partitions 34 themselves or another arrangement for separating the beads, for example a hollow passage defined by the casing interior.
[0023] The beads 12 are preferably arranged in a single file within each column 30 although the columns may be wider to hold beads stacked randomly. In a preferred embodiment, the bead dispenser holds beads of different colours and of similar sizes.
[0024] The dispensing mechanism 20 is preferably a biased mechanism that includes a moveable dispensing body 22 having a cavity 24 where the body is moveable laterally across the width of the dispensing casing 18. An inlet aperture 26 is provided in the body 22 above the cavity 24 and an outlet aperture 28 is provided in the body 22 below the cavity 24. The apertures are offset such that the beads are made to follow a diverted path through the body from the inlet to the outlet and on through the dispensing nozzle. A sloping ramp 27 inside cavity 24 urges a bead entering through inlet aperture 26 towards outlet aperture 28 to place the bead in position at the outlet aperture 28 ready for dispensing when the mechanism is released.
[0025] The biased dispensing mechanism is activated by a trigger in the form of a push button 25 located on the exterior of the housing and forming an extension of the dispensing mechanism body. Figure 4(a) illustrates the dispensing mechanism 20 in a rest/released position. The button 25 extends through an opening 19 in the dispensing casing and is pressed in order to move the dispensing mechanism body radially across the dispensing casing to a pressed position as illustrated in Figure 4 (b) to align the inlet aperture directly underneath a bead column. This allows access of a bead 12 in the column into the cavity 24.
[0026] Releasing the button 25 allows the dispensing mechanism body 22 to return back across the dispensing casing to the released position illustrated in Figure 4(c) and thereby close the access of the bearing columns to the cavity. This in turn aligns the outlet aperture 28 with a corresponding aperture 29 in the dispensing casing 18. This allows access for beads in the body to pass under gravity through to and out of the dispensing nozzle.
[0027] When the mechanism is in a pushed position and the dispensing mechanism is ready to receive a bead, outlet aperture 28 is misaligned with its corresponding outlet 29 in the dispensing casing body so to prevent beads from escaping through the dispensing mechanism while the button 25 is pushed. In practice, the size and shape of cavity 24 may be such to hold two or more beads so that more than one bead is dispensed upon release of the button. Alternatively, the dispensing mechanism 20 may be structured to dispense only one bead with every press and release of the button.
[0028] The dispensing mechanism is spring biased towards the released/rest position illustrated in Figures 4 (a) and 4(c). A spring 23 is located between the movable body 22 and the dispensing casing 18.
[0029] At the opposite end of the elongated housing to the dispensing nozzle there is provided a removable lid 35 which is removed to provide access to the storage casing 16 for refilling the bead columns. The lid is preferably shaped as a funnel and has a central hollow sleeve 36 through which a bead can pass. The amount of beads that can be held in the funnel of the lid is substantially equal to the number of beads required to fill a bead column. To assist a user with filling the bead columns the sleeve 36 is placed inside a bead column tube and the funnel lid filled with beads. The beads will then flow under gravity through the shaft 26 and into the tube.
[0030] As illustrated in Figure 5 the bead dispenser 10 may also comprise a bead removal tool 52 which is used to pick up a stray or misplaced bead to replace the bead in the dispenser or elsewhere. Removal tool 52 comprises a stem 54 and an adhesive portion, or pad 56, which inserts into one end of stem 54. Adhesive pad 56 is made of a thermoplastic rubber or a similar material having adhesive and sticky qualities and to which a bead will attach for picking up.
[0031] Removal tool 52 may be stored in hollow sleeve 36 in the lid 35 with adhesive pad 56 exposed. Removal tool 52 may be used either on its own separated from the housing 14 of bead dispenser 10 as illustrated in Figure 5 or may be used while stored in situ in lid 35. A cap (not shown) may cover adhesive pad 56 and protect it from dirt and the like.
[0032] The bead dispenser is similar in shape to a pen. It allows a user to easily manipulate a variety of bead types in a simple and effective manner. In terms of beads used for decorating the bead dispenser 10 reduces any difficulties and frustrations associated with handling and placing beads in position where required.
