Description
BACKGROUND OF THE INVENTION
Containers for pills designed to package, protect and dispense the
product have heretofore been proposed. Ideally containers of this
type are compact, relatively tightly sealed so as to exclude dust
and moisture and should be characterized by the ease by which they
are used. An important consideration is the ease of filling the
pill compartment and manipulation of the dispensing mechanism. A
common expedient is to use snap-on or hinged covers of various
designs all directed to providing a container which is flat,
compact and free of protuberances, while at the same time being
convenient to extract from the pockets of clothing or a purse. Such
devices must be easy to clean and reassemble. Any dispensing
mechanisms used should be not only easy to use, and essentially
foolproof but also be positive in their action so that the pills
are not broken or accidentally dispensed in one's pocket.
Characteristically in an art of this kind the dispenser which looks
the best is not always the easiest to fill or use and the container
that is easiest to fill and use may be grotesque or may not always
dispense the pills without breakage or lockup. Protection of the
contents of the container from contamination appears to be
secondary in some designs. The mere act of filling and closing some
pill dispensers is a problem in dexterity. For others a person must
watch the sequence of parts rotation and registry very carefully to
get a pill out and prevent lockup of the parts. Changes in
temperature and humidity sometimes adversely affect the operation
of the moving parts of a pill box. Other designs are annoying to
carry on the person and still others are either expensive to
manufacture or too cheaply made to be practical.
SUMMARY OF THE INVENTION
The instant invention concerns a pill dispenser formed of two or
three simple molded parts which are readily assembled by inspection
and wherein the selection of a particular pill for ejection from
the container is a positive simple stroke or rotation of one of the
parts in relation to the other in a natural sequence. The
dispensers of this invention are easy to take apart for cleaning
and refilling. They are assembled by bringing the mating parts
together in a press fit or snap-fit relationship. The dispensers in
assembled condition are essentially flat and circular with smooth
rounded edges so as to be convenient to carry and use and can be
formed from molded plastic parts.
In one embodiment of this invention a two-part molded plastic
dispenser is provided to include a circular flat bottom member with
an outer circumferential upstanding wall having an outer opening or
slot for a pill at one point in the circumference. A secondary
arcuate dividing wall spaced inwardly therefrom defines the pill
receptacle space and is provided with a pill slot offset from the
first pill slot. Two smaller inner walled recesses or compartments
serving as radial guide spaces are also provided substantially
opposite the outer pill slot. At the base of the walls at
appropriate points arcuate recesses are provided. The cover
comprises a flat disc matching the circular shape of the bottom
member, having a pattern of interconnecting and spaced subwalls
depending from one surface and also having ribs at appropriate
places which snap into the recesses to hold the cover and bottom
together in a rotative relationship.
One configuration of subwalls on the cover member locks into walled
recesses to form limit stops for the relative rotational movement
of the bottom and cover members. The other configuration of
subwalls forms a radially movable stop and opening so that in
closed position the inner pill slot is closed while the outer pill
slot is open. By rotation of the top and bottom members, within the
limits of the stops, the opening registers with the inner slot to
receive a pill in one position and with outer slot to eject the
pill from the container in a second position. The walls of this
form of dispenser are always closed.
In another embodiment the outer upright subwall of the bottom
member has two openings, one a pill slot and the other a longer
handle slot; and the inner subwall, defining the pill compartment,
has an enlarged pill slot opening. The outer wall of the cover
member has a pill slot and a handle slot matching these openings in
the subwall of the bottom member but set inwardly the depth of the
outer wall to be rotative and concentric therewith. An arcuate flat
U-shaped pill expelling member is sandwiched between the top and
bottom members fitting concentrically between the inner wall of the
top member and the inner wall of the bottom member. The impeller
has an inner camming surface terminating in a radial slot on one
side and a tab or handle member on the opposite side. In this
embodiment all three members, the cover, the bottom and the
impeller are rotatable with respect to each other within the limits
of the tab which extends radially into the longer handle slot. The
parts can thus assume four positions; a closed position, a position
to receive a pill in the radial slot of the impeller, a position
conveying the pill to the outer pill slot and cutting off the entry
of more pills by the camming action and a position of delivery of
the pill outside the dispenser.
A pill dispenser is also provided wherein multiple radially spaced
pockets are provided for rotation in respect to a fixed opening in
the sidewall of the cover. An inner wall segment is provided
opposite the opening to engage upon the pockets and seal a selected
pill from the balance of the pills in the dispenser for ejection
out of the opening.
In addition a pill dispenser is provided operating on a simple
principle of sequentially opening a space on the inside to the pill
contents to select a pill and then closing that side while the
opposite or outside of the space is opened for ejection of the
pill.
All embodiments of this invention are characterized by the shape,
tolerances, spacial relationships and dimensions of the parts to
attain the smoothness of operation of the parts and the unique
facility with which a pill is selected for ejection from the
dispenser. Furthermore an aspect of the invention is the provision
of sealing and snap-fit relationships between the cover and bottom
members and also between certain of the pill-selecting means that
are practical, easy to manipulate and do not increase the molding
or material costs.

THE PREFERRED EMBODIMENT
Throughout the description of the detailed parts of the dispenser
container of this invention the terms "cover member" and "bottom
member," "depending" and "extending" or "top" and "bottom" are used
to describe the principal elements and their parts as they are
oriented in the drawings and it is to be understood that the
dispensers of this invention can be otherwise oriented so that
these elements and their parts are in a reversed spacial
relationship and perform the same functions without regard to such
spacial attitude and are so regarded without the necessity of
changes in such nomenclature. It is further to be understood that
the items to be contained and dispensed, though referred to herein
as pills and tablets and illustrated to be spherical, can be any
shape or configuration including capsules or gelation balls or
other small objects which one may desire to store or contain for
individual release in the manners illustrated.
Referring to FIG. 1 there is shown the cover member 10 and the
bottom member 12 of a round flat dispenser as these parts appear in
disassembled relationship, e.g., as produced by the molding machine
or as opened for the purpose of inserting the pills or tablets 14,
shown in FIGS. 3-5. The cover member 10 is formed with a
disc-shaped flat body 16 having the circular outer peripheral edge
18.
The cover member 10 has a pair of downwardly depending flat tabs or
stop members 20 and 22 affixed to the underside or molded as
integral parts of the cover member 10. The tabs 20 and 22 are
essentially rectangular in configuration and are positioned
radially on the cover member, being spaced inwardly from the
periphery 18 and outwardly from the center 19 of the disc 16. The
tabs 20 and 22 can have other solid shapes, as will become apparent
from this description, and may also be circumferentially spaced
from each other different distances than that illustrated, as will
also be further described or become apparent.
The next feature of the cover member 10 is the depending arcuate
wall 24 having at the ends the radially disposed guide walls 26 and
28. Circumferentially spaced from the wall 28 there is provided the
retainer wall 29 the functions of which will be described. The
arcuate wall 24 is concentric with the periphery 18 and a segment
of a circle whose center is coincident with the center 19 of the
disc 16. The guide walls 26 and 28 are essentially identical as
will be described. The guide walls 26 and 28 and arcuate wall 24
combine to form a gate which closes and opens the container and
functions as an actuator or pistonlike member, as will be
described.
The bottom member 12 has the circular peripheral edge 30,
substantially the same diameter as the cover member 10 and
comprises the flat disc body 32 the center which is indicated at
34. The bottom member 12 is provided with the upstanding circular
outer wall 36, which is spaced inwardly, as at 38 from the
periphery 30, with the opening 40 therein, formed by the spaced
ends 42 and 44. Secondary or intermediate walls 46 and 48 are
similarly provided with their outer ends joining the inside of the
wall 36 at opposite sides of the bottom member, as indicated at 50.
The walls 46 and 48 (See FIG. 3) have the spaced end portions 46a
and 48a that are arcuate and concentric with and spaced inwardly
from the outer wall 36 on each side of the opening or slot 50
defined at their termini. The opening 50 is offset
circumferentially from the opening 40 in the wall 36. FIG. 3 also
shows that the retainer wall 29 is spaced from the wall 28 a
distance slightly greater than the circumferential width of the
opening 40 in wall 36.
On the opposite side from both openings the bottom 12 has the
arcuate wall 52 and the radial walls 54, 56 and 58 formed
integrally therewith to the inner surface of the wall 36 and
providing the arcuate recesses or pockets 60 and 62 therebetween.
In the circumferential and radial spacing illustrated it is seen
that the cover member 10 fits down upon the bottom 12 with the tabs
20 and 22 in the recesses 60 and 62 respectively, and, with the
guide wall or actuator 24 within the space 64 between inside of the
arcuate wall 36 and the outer surfaces of the concentric wall
portions 46a and 48a as shown in FIG. 3, while the spaced top and
bottom surfaces of the discs 16 and 32 and the balance of the walls
form a compartment to contain the tablets or pills 14. All of the
top edges of the walls 36, 46 and 48, and the walls of the actuator
are coplanar so that the under surface of the disc 16 forms a
dusttight and moistureproof seal against these edges.
It is to be observed that the walls 26 and 28 have the ribs or
beads 66 and 68 at their outer corners and the retainer wall 29
also has the rib or bead 70 at the outer corner, all spaced from
the underside of the disc 16. Also the wall 36 has the inner
circumferential recess or groove 72 at the juncture with the face
of the disc 32. As the cover member 10 and bottom member 12 are
brought into the mating relationship shown in FIG. 3 these beads
and the recesses mate as shown in FIG. 6, in a snap-fit
relationship that holds the cover and bottom members together and
allow them to be rotated in relation to one another. The
relationship illustrated in FIG. 6 wherein the recess 72 of the
wall 36 of the bottom member 12 is shown in engagement with the
bead 70 of the guide wall 29 extending from the cover member 10, is
representative of the structures of other bead-recess parts in this
embodiment and other embodiments of the invention. Although the
recess 72 is shown to extend around the periphery of the bottom
member 12, it is apparent that this recess can be discontinuous and
be provided in suitably dimensioned segments at those places to
engage a bead of an adjacent part of the cover member 10. Also
those parts of the cover member 10 shown to have beads are not all
inclusive and it is only necessary that a sufficient distribution
of the beads 66, 70, etc., on one side and the bead 74 on the other
side, be provided so that the cover and bottom members are held in
a snap-fit rotational relationship. If desired the bead-recess
relationship can be reversed on these parts.
Referring to FIGS. 3, 4 and 5 the operation of the device is as
follows. With pills 14 in the space defined by the walls 46, 48 and
36 and 52 between the cover and bottom members snapped together,
the closed position of the dispenser is shown in FIG. 3. The tabs
20 and 22 are against the walls 54 and 60, the arcuate wall 24
closes the opening 50 and the space 80 between the wall 28 of the
actuator and the wall 29 registers with the opening 40 defined by
the termini 42-44 of the wall 36. This position of the parts is the
same as shown in FIG. 5.
The dispenser is tilted slightly so that the pills 14 slide to the
inside of the walls 46-48 and gather at the opening 50. The cover
10 is rotated clockwise, indicated by the arrows 82, or in relation
to the bottom member 12 (or the bottom member 12 can be rotated
counterclockwise, or both members moved simultaneously in opposite
directions) to attain the open position shown in FIG. 4. Here the
tabs 20 and 22 have swept through to the other ends of the arcuate
spaces 60 and 58, respectively, and the space 80 has moved to
register with the space 50 so that the pill 14' falls or slides
therein. The combined spaces 50 and 80 only accommodate one pill at
a time and reversal of the position of the cover and bottom members
causes the actuator wall 28 to push the pill 14' to a point
opposite the opening 40 and be dispensed. The arcuate wall 24
sweeps by the opening 50 and closes the container as before, e.g.,
into the position of FIG. 3 or FIG. 5.
To assist in the finger manipulation of the dispenser the outer
surfaces or peripheral edges of the cover and bottom members can be
knurled, as illustrated at 86. The top surface of the cover member
10 or the bottom surface of the bottom member can bear indicia to
label the contents or type of tablet contained in the dispenser.
The space between the walls 26--28 can be molded in a solid
configuration if desired and, similarly, the walls 20 and 22 can be
any desired thickness with appropriate change in the size of the
spaces 60 and 62 to accommodate same. Only one tab or buttress 20
and recess 60 can be used if desired. The spaces 88 can be filled
or differently shaped in the molding of the bottom member as long
as the arcuate concentric relationships of the walls 46a -48a and
the outer wall 36 opposite the openings 50 and 40-44 are
maintained.
Referring to FIGS. 7-11 a modification of these structures is shown
wherein the actuator or impeller is made as a separable movable
structure between the cover and bottom members which bear the
snap-fit rotational relationship heretobefore described. In this
embodiment (FIG. 7) the top member 100 has the disc-shaped flat
bottom wall 102 and the depending peripheral walls 104 and 106
broken or spaced from each other by the opening 108 on one side and
the longer opening or slot 110 on the other side.
The bottom member 112 has the flat disc body 114 and the upwardly
depending circumferential walls 116 and 118 separated from each
other by the opening 120 on one side and the longer slot 122 on the
other side. The walls 116 and 118 are radially inset to provide the
shoulder or flange 124 around the inner side of the bottom member
112 and have the outer snap beads 126 and 128 which mate with the
inner circumferential grooves or recesses 130 and 132 at the base
of the walls 104 and 106 in the assembled condition of these
parts.
The bottom member 112 has the inner circular wall 134 which is
discontinuous to define the larger opening 136 directed toward the
wall 116. The concentric arrangement of walls 116 and 118 with the
discontinuous wall 134 about the center 138 defines a circular
channel or annulus to slideably receive the circular flat impeller
140 having the handle or tab 142 on its periphery and the slot 144
opposite thereto. The wall 134 forms a hub or bearing for the
impeller which engages same by means of the essentially circular
inner surface 146, except for the outwardly directed cam surface
148 leading to the opening 144. Thus the end 150 of the impeller
140 fills the cross-sectional area of the annulus between the walls
134 and 116-118 while the end 152 is smaller than this annulus. The
impeller has a depth substantially the same as the depth of the
annulus between the assembled cover and bottom members and this
depth is slightly greater than the thickness of the tablets 14 so
that the tablets can pass therethrough.
FIG. 8 shows the assembled condition of the cover, bottom and
impeller members wherein the tab 142 extends through the
overlapping elongated openings 110 and 122, the wall 118 extends
over and closes the slot 120 and the cam 148 partly closes the
opening 136 while the slot 144 is closed within the annulus.
Thus by turning the bottom 112 counterclockwise in relation to the
cover 100, e.g., in the direction of the arrow 154, the elongated
slots 110 and 122 now register with one another (FIG. 9) and the
opening 136 and cam 148 provide access to the slot 144 of the
impeller 140 so that, with the dispenser held at a slight angle the
pill 14' falls into the slot 144 of the impeller. Also the slots
108 and 120 register in this position of the parts.
Then the tab 142 is pushed in the direction of the arrow 156 in the
registered slots 110 and 122 (FIG. 10) which causes the next tablet
14" and those behind it to be lifted or pushed up or along the cam
148 as the wall 134 moves in relation to the impeller and the
tablet 14' is entrapped in the slot of the impeller. As the tab 142
reaches the end of the registered slots 110 and 122 (FIG. 11) the
slot 144 containing the tablet registers with the slots 108 and 120
and the tablet 14' is dispensed.
The dispenser of this invention can take still another modified
form in which the impeller and the inner retaining walls are
omitted and a plurality of peripheral openings on the bottom member
cooperate with a closure member and outer slot in the cover member
to accomplish these purposes of selective dispensing of a tablet or
pill as shown in FIGS. 12-16.
Here the cover member 200 has the flat disc body 202, the circular
peripheral edge 204 and the depending circular wall 206 which is
inwardly offset from the edge 204 to form the flange 208. The wall
is discontinuous to define the outer slot 210 between the ends 212
and 214. Radially spaced inwardly and opposite to the slot 210
there is provided the retainer wall 216 having the small notched
corners 218 and 220 on the outer surface which extend the height of
the wall. The inner peripheral junction of the wall 206 with the
body 202 bears the circumferential recess 222 (FIG. 17) similar to
the embodiment shown in FIG. 7.
The bottom member 224 has the flat disc-shaped body 226 whose
center is illustrated at 228 and a series of peripherally equally
spaced, identically shaped segmental wall members 230. Each wall
member 230 has an outer surface 232 which is concentric with the
circular edge 234 and spaced inwardly therefrom to form the
peripheral circumferential flange 235. At the top of each wall
segment there is provided the segmental or arcuate bead 236. Each
wall segment 230 is triangular in shape, having the converging
walls 238 and 240 and is spaced from the neighboring wall segment
to define a pocket or radial recess 242. The walls 238 and 240
converge to form an inner resilient pointed edge 244 thereon.
The effective height or radial width of each wall segment from the
inner point 244 to the arcuate base wall 232 is slightly greater
than the radial distance between the inner surfaces of the wall 206
and the outer surface of the retainer wall 216. This difference is
represented by the depth of the respective notches 218 and 220. The
effective length of the retainer wall 216 is slightly greater than
the opening 210 and also greater than the radial recesses 242
between adjacent pairs of said segmental wall members 230. The
beads 236 snap fit into the circular recess 222.
Thus the cover member 200 fits upon the bottom member 224 with the
wall 206 encompassing the outer surfaces 232, the segmental wall
members 230 and with these wall segments adapted to pass between
the wall 206 and the retainer wall 216 as shown in FIG. 15, with a
stop action each time a pair of points 244 of the wall segments
comes opposite the notches 218 and 220 (shown in FIGS. 14 and
16).
The cover 200 and the bottom 224 are rotatable with respect to each
other to the closed position shown in FIGS. 14 and 15 with the
retainer wall across the points of a pair of segmental walls and
rotatable in either direction, such as in the direction of the
arrow 250 (FIG. 15) whereby the space between the next pair of
segmental walls 230 and 230' becomes accessible to or already
contains a tablet 14' and continued rotation of the parts will
bring this tablet opposite the opening or slot 242 for ejection
from the dispenser. Conversely the cover can be rotated opposite to
the direction of the arrow 250 in which event the tablet 14" will
be ejected. In the closed position the tablet compartment is
effectively sealed by the closely fitting parts. Each partial turn
of the cover and bottom members causes a stepwise or intermittent
stop point as the points 244 engage and disengage from the notches
218 and 220. The dispenser shown in FIG. 12-17 can be operated by
relative rotation in either direction. If desired the inner surface
of the bottom member 224 can have a slight recess to provide the
circumferential edge 252 contiguous to each of the points 244 to
provide a slight retaining wall over which the tablets must be
jiggled to be dispensed.
The next embodiment of this invention is shown in FIGS. 18-23
wherein the cover member and impeller member of the embodiment
shown in FIGS. 7-11 have been combined. In FIG. 18 the cover member
300 has the circular recess 302 having a central blind bore 304
with the undercut or enlargement 306 in the bottom. The outer wall
308 (FIG. 21) and the inner wall 310 of the recess 302 are
concentric in part and the cover is provided with the tangential
flat walls 312 and 314 joined to the outer concentric wall 316
which is interrupted by the opening or notch 318 defined by the
ends 320 and 322. The opening 318 has the top wall 324 connecting
between ends 320 and 322. The wall or side 314 has the depending
tab 326.
The bottom member 330 has the flat disclike body 332 and the curved
edge 334 whose center is occupied by the protuberance or stub axle
336 having the head 338. Concentric with the axle 336, the wall 340
extends around the surface of the flat disc 332 and is interrupted
to define the notch or opening 342 between the ends 344 and
346.
The bottom member has the flat sides 348 and 350 connecting to the
outer edge 352 having the flange wall 354 interrupted by the notch
356 defined between the ends 358 and 360. The edge 352 and the wall
354 have a circular curvature about the central axle 336.
As illustrated the cover member 300 snaps upon the bottom member
330 with the bore 304 and undercut 306 receiving the axle and head
as illustrated in FIG. 20 and with the circular wall 340 nested
within and concentric with the wall 310 of the recess 302. The edge
316 fits concentrically within the inner surface of the flange 354
as shown in FIG. 21 with the recess 302 encompassing the wall 340
to define a compartment to contain the tablets 14. The tab 326
extends just sufficiently beyond the bottom surface 362 to form a
stop member and engage the surface 348 of the bottom member 330 as
shown in FIG. 22.
Thus the cover member 300 and the bottom member 330 have limited
rotation in one direction about their common axis 340-336 as
determined by the angular difference between the surface edges 314
and 448 (FIG. 21) and the limitation imposed by the stop tab 326.
It is apparent that a convenient form of tablet dispenser if formed
by these structures since partial rotation of the cover 300 from
the position shown in FIG. 21 to the position shown in FIG. 22 is
accomplished by holding the container between the cradled fingers
of the hand and pressing the sides 314 and 348 into coplanar
relationship (FIG. 22). This brings the notch 318 into registry
with the opening 342 to allow one tablet 14' to enter. Then pushing
the surface 312 so that it is flush with the surface 350, on the
other edge of the assembly and by the same thumb and finger action,
returns the parts to the closed condition of FIGS. 21 and 23, but
carries the tablet 14' to a position opposite the opening 356 in
the wall 352, whereby it is released.
