[0001] The present invention relates generally to a dispenser for holding a plurality of
individual items and allowing them to be dispensed.
[0002] A common form of dispenser of this type is a tablet dispenser for medicaments, sweeteners
or the like product. Tablet dispensers usually comprise a body for containing a plurality
of items to be dispensed, and an actuating means operable by the user to cause an
item to be dispensed from the body. The actuating means may be, for example, a push-button
(EP 0 894 736), a rotatable part (US 6,142,337) or a squeezable shell (WO 00/68109).
[0003] In known tablet dispensing systems the tablets are dispensed directly out of the
dispenser. For example, medicaments are dispensed directly into the hand of the user,
and sweetening tablets are dispensed directly into a beverage.
[0004] There are a number of disadvantages to this type of system, for example: tablets
may be misdirected and then lost as they are dispensed; if a user's hand is required
to catch the tablets as they are dispensed this prohibits two-handed operation of
the actuating means, which may be necessary for those without the strength or dexterity
to operate the actuating means with a single hand; the items which will be dispensed
may be water-soluble and therefore it would be preferable not to dispense them directly
onto a user's hand; if items are dispensed directly into a beverage the number of
tablets dispensed may be forgotten during the dispensing operation and therefore an
accurate dose will not be possible.
[0005] The present invention seeks to address the above problems.
[0006] The present invention provides a dispenser comprising a container body which, in
use, contains a plurality of items to be dispensed, a dispensing part having an orifice
movable from a non-dispensing position in which items cannot pass through the orifice
to a dispensing position in which an item can pass from the container body through
the orifice, and an actuating part operable to move the dispensing part to the dispensing
position, characterised that, the dispenser is arranged so that, in use, items passing
through the orifice are released into the actuating part.
[0007] The present invention therefore uses the actuating part not only to actuate item-release
means, but also to catch items as they are dispensed. Once the required number of
items has been dispensed the items can be removed from the actuating part.
[0008] The actuating part may be removable completely from the remainder of the dispenser
so that the items can be easily removed.
[0009] The dispenser may be adapted to dispense items individually into the actuating part.
This allows the required number of items to be accurately dispensed into the actuating
part prior to the items leaving the dispenser.
[0010] The dispensing orifice may be defined by one or more dispensing members movable in
response to movement of the actuating part. The or each dispensing member may be adapted
to move radially outwardly or inwardly to move the dispensing part to the dispensing
position.
[0011] The number and form of the dispensing member/s can be matched to any particular application.
The only essential requirement is that it/they define an orifice adapted to restrict/allow
the passage of items when the dispensing part is in the non-dispensing/dispensing
position.
[0012] The actuating part may include a projection which, together with the dispensing member/s,
defines a restricted dispensing zone adjacent the orifice into which a single item
can pass when the dispensing part is moved to the dispensing position. Inclusion of
the projection therefore allows items to be dispensed individually into the actuating
part.
[0013] The projection may also be adapted to cause the dispensing member/s to move as the
actuating part is moved. The projection therefore serves a dual function.
[0014] The dispensing part may be biassed towards the non-dispensing position so that following
the dispensing of one or more items, the dispensing part automatically returns to
the non-dispensing position.
[0015] The dispenser may further comprise a tamperband. The tamperband may be situated such
that it must be removed before the actuating part can be operated to move the dispensing
part. The dispenser cannot be operated before the tamperband is removed.
[0016] Where a plurality of dispensing members are used and they move radially outwardly
to move the dispensing part to the dispensing position, they may define a circular
orifice. In the non-dispensing position the orifice defined by the dispensing members
is smaller than an item. When the actuating part is operated the dispensing members
move radially outwardly and increase the size of the circular orifice.
[0017] Where the dispensing members move radially inwardly the members may define an ovoid
orifice in the non-dispensing position. When the actuating part is operated the dispensing
members move radially inwardly and circularise the orifice. The items are shaped such
that they cannot pass through an ovoid orifice but can pass through a circular orifice
which may have the same circumference; for example the items could be disc-shape or
spherical.
[0018] The present invention will now be more particularly described, by way of example,
with reference to the accompanying drawings, in which:

which illustrate the working of the dispenser;

according to a second embodiment of the present invention;
Fig.6 is a section of Fig.2 shown with an actuating part attached to form a complete
dispenser; and
Figs.7a to 7f show a series of magnified sections of part of the dispenser of Fig.6,
which illustrate the working of the dispenser.
[0019] Referring first to Figs. 1 and 2 there is shown a dispenser generally indicated (10)
comprising a body part (20), a dispensing part (30) and an actuating part (50) [Fig.1
shows just the parts (20, 30) before the part (50) has been added].
[0020] The body part (20) is a cylindrical container for holding items to be dispensed.
The body part (20) is closed at one end by a disc-shape end plate (21), and the dispensing
part (30) is connected to the other end of the body part (20).
[0021] Referring now also to Figs. 3a to 3f, the actuating part (50) is a cap comprising
a top plate (51) and a cylindrical skirt (52) which depends from the periphery of
the plate (51).
[0022] The top plate (51) includes a central frustoconical depression which forms a frustoconical
projection (53) in the interior of the actuating part (50). The projection (53) defines
an annular channel (55) around its periphery.
[0023] At the open end of the skirt (52) is an annular bead (54) the purpose of which is
described in more detail below.
[0024] The dispensing part (30) comprises a lower connecting portion (31) and an upper dispensing
portion (32). The connecting portion (31) comprises a lower tubular skirt (33) sized
to fit inside the body part (20). The outer wall of the connecting portion (31) has
a flange (34) approximately half way along its length. The flange (34) acts as a depth
stop to limit the amount the connecting portion (31) can be inserted into the body
part (20).
[0025] Below the flange (34) the outer wall of the connecting portion (31) has an annular
groove (35) sized and positioned so that when the connecting portion is fully inserted
into the body part (20) it aligns with an annular bead (22) on the inner surface of
the body part (best shown in Figs. 3a to 3f). The bead (22) thereby retains the dispensing
part (30) in the body part (20).
[0026] Above the flange (34) the connecting portion (31) extends with an upper tubular skirt
(36). The upper tubular skirt (36) includes an annular groove (37) which is trapezoidal
in section. The groove (37) receives the bead (54) from the inside surface of the
cap skirt (52) to clip the actuating part (50) onto the dispensing part (30) in such
a way that the actuating part (50) can move axially with respect to the dispensing
part (30), with the bead (54) sliding axially in the groove (37).
[0027] The dispensing portion (32) of the dispensing part (30) extends from the upper tubular
skirt (36). The dispensing portion (32) comprises three identical dispensing members
(38).
[0028] Each of the members (38) includes a link portion (39) which extends orthogonally
from the upper tubular skirt (36) to connect the member (38) to the skirt (36) in
such a way that the member (38) can resiliently flex in the radial direction. Each
member (38) further comprises a curved plate (40) which is shaped so that together
the members (38) form a frustoconical structure with a central circular orifice (41)
at its end remote from the link portions (38). The orifice (41) is shaped and configured,
i.e. adapted, to the items to be dispensed.
[0029] Each of the members (38) further includes a leg (42) which extends from the outer
surface of the plate (40).
[0030] The lower edge of the skirt (52) of the actuating part (50) is attached to the flange
(34) by an annular tamper evident band (60), the purpose of which is described below.
[0031] The operation of the dispenser will now be described in relation to Figs. 3a to 3f,
which show the upper part of the dispenser in an inverted, as used, state compared
to Figs.1 and 2
[0032] Fig.3a shows the dispenser in an unopened and unused configuration. The tamper band
(60) is connected between the lower edge of the skirt (54) and the flange (34).
The actuating part (50) is thereby locked in a first axial position in which the bead
(54) is at the upper end of the groove (37).
[0033] In the first axial position the dispensing member legs (42) are held away from the
actuating part projection (53) and the members (38) are in a rest position in which
the orifice (41) is too small for an item to pass through.
[0034] Fig.3b shows the dispenser with the tamper band (60) removed. There is now a gap
(G) between the lower edge of the skirt (52) and the flange (34).
[0035] In Fig.3c the actuating part (50) has been moved to a second, lower axial position.
This is possible because of the gap (G) and because the bead (54) can slide from the
upper end of the groove (37) to the lower end. The movement of the actuating part
(50) causes the legs (42) to contact the projection (53) and to move progressively
down its widening exterior surface. As a result the dispensing members (38) pivot
about the intersection between the link members (39) and the plates (40).
[0036] As the members (38) are splayed radially outwardly the circular orifice (41) increases
in size until a first item (70) can pass through. The first item (70) passes through
the orifice (41) and onto the projection (53). The space between the orifice (41)
and the projection (53) is sufficient only for a single item; accordingly only a single
item can be released from the orifice (41) whilst it is at its increased size. When
the actuating part (50) is released, the resilience of the dispensing members (38)
forces the actuating part (50) back to the first axial position, shown in Fig.3d.
The first item (70) can now fall into the channel (55) surrounding the projection
(53). A second item (75) cannot pass through the now constricted orifice (41).
[0037] If the dispenser (10) is operated again the second item (75) can now pass into the
space between the orifice (41) and the projection (53), as shown in Fig.3e. When the
actuating part (50) is released again the second item (75) falls into the channel
(55) and a third item (80) moves to the orifice (41), but cannot pass through.
[0038] When the required numbers of items has been dispensed into the channel (55) the actuating
part (50) can be removed by pulling it axially so that the bead (54) passes out of
the groove (37). The actuating part (50) now functions as a cup which contains the
items ready for use, as shown in Fig.4.
[0039] A second type of dispenser (110) is shown in Figs. 5 to 7, in which like reference
numerals refer to like parts in relation to Figs. 1 to 4. The dispenser (110) is of
the same general construction as the dispenser. However, whilst in the first dispenser
(10) the dispensing members (38) are adapted to move radially outwardly, in this second
dispenser (110) the members (138) are adapted to move radially inwardly.
[0040] In this embodiment the dispensing part (130) comprises two dispensing members (138)
each of which includes a link portion (139) extending from the top of the groove (137).
The plates (140) together define a hemispherical structure with an elliptical orifice
(141) at its centre.
[0041] The actuating part skirt (152) comprises a lower first skirt portion (156) and an
upper second skirt portion (157) of reduced diameter. The portions (156, 157) are
joined by an intermediate, inwardly inclined portion (158).
[0042] A central projection (153) depends from the top plate of the actuating part.
[0043] The operation of the dispenser (110) is similar to the dispenser (10) in that the
tamper band (160) is first removed and the actuating part (150) is then depressed.
In this dispenser (110), however, depressing the actuating part (150) causes the legs
(142) to progressively contact further down the intermediate skirt portion (158),
which forces the dispensing members (138) radially inwardly (Fig.7c). In this embodiment
the plates (140) are formed so that they contact each other in the rest position (see
Fig.5). Accordingly, when the dispensing members (138) are forced inwardly the plates
(140) are forced against each other and the areas around the orifice (141) are bowed
outwardly. This tends to circularise the oral orifice (141).
[0044] Accordingly, spherical items (170, 175, 180) can pass through the orifice (141) in
the same sequence shown for the first dispenser (10).
[0045] The central projection (153) does not cause the members (138) to move, but does restrict
dispensing of items in the same way as the projection (53) of the first embodiment.
