1. A dispensing unit for dispensing non-pressurized materials
comprising a container having an upper container with a body formed
of a substantially rigid material with an opening in the bottom
thereof and a separate lower container extending directly below the
upper container, said lower container having a body formed of a
substantially rigid material and having a top opening substantially
that of the circumference of the lower container, a puncturable
partition extending completely across the top opening of the lower
container, said partition being planar and extending parallel with
the bottom of the lower container and separating said upper and
lower containers without reducing the volumetric capacity of each
container so that each container separately contains a separate
non-pressurized material, means for coupling said upper and lower
containers adjacent the bottom of the upper container and the top
of the lower container so that when coupled the bottom of the upper
container is immediately adjacent the top of the lower container
and they form an integral unit in which the circumference of the
upper and lower containers are substantially the same
circumference, an axially depressible member positioned within said
upper container and manually depressible to engage and puncture the
partition to permit the material within each container to be mixed
while said separate containers are connected as a unit, said
axially depressible member comprising a hollow tubular plunger
having a discharge spout at the outer end in axial alinement with
said tubular plunger and puncturing means at the opposite end for
puncturing the partition, said tubular plunger having an opening at
said opposite end adjacent said puncturing means so that when said
tubular member is depressed the material in said lower container
will pass into said plunger by gravity flow when the unit is
inverted, said plunger having an opening communicating with the
upper container through which the material passes and mixes with
the material from the lower container before it is discharged by
gravity flow through said axially alined discharge spout.

Description
BRIEF SUMMARY OF THE INVENTION
One of the objects of this invention is to provide a container
comprising a plurality of compartments with a partition or wall
between said compartments, with each compartment containing a
separate material so that the material is kept separated until it
is ready to be used by the consumer, at which time the separating
wall or walls may be ruptured or punctured to permit the separated
materials to be comingled and to be dispensed in such comingled
condition.
In handling a product such as hair coloring or the like, the
materials are usually contained in two individual and separate
containers, that is, one container will contain the hair coloring
material and the other container will contain a peroxide, which the
consumer mixes and then applies to the hair. The object of this
invention is to provide a single unit comprising two or more
compartments, containing in one compartment the coloring material
and in the other compartment the peroxide, and which has means for
puncturing or rupturing the partition between the compartments so
that the peroxide and the coloring material becomes mixed inside of
the containers and in this mixed condition can be dispensed through
a single spout.
Another object of this invention is to provide in a single unit a
multiplicity of compartments, each containing a different
ingredient or composition which can be combined within the unit and
be dispensed from the unit through a single nozzle.
Other objects will become apparent as this description
progresses.

FIG. 8 is a perspective view of the plunger and cutting member
shown in the second embodiment, and
FIG. 9 is a sectional view taken on line 9--9 of FIG. 7.
In FIGS. 1 through 5 there is shown a dispensing unit which is
generally indicated by the numeral 10 and same includes a lower
container indicated by the numeral 12 which may be made of glass of
the like and which forms a lower compartment 14. The neck 15 of
said container is externally threaded as at 16 and the neck has a
reduced diameter in relation to the body of said container. Adapted
to be secured to said bottom container 12 is a tubular member
generally indicated at 18, which serves to form a second or upper
compartment 20, as will be described. A partition generally
designated by the numeral 22 consists of a membrane which prior to
puncturing serves to keep the material in the compartments 14 and
20 separated. Said partition 22 which is capable of being punctured
is positioned over the top of the bottom container 12. An annular
sleeve 24 which is internally threaded as at 25 and having a top
flange 26 is adapted to be screwed to the neck 15 of the bottom
container 12 and to hold therebetween the partition of membrane 22
to close the top of the bottom container 12. The tubular body 18,
which may be made of plastic or like material, is positioned on the
sleeve 24 and engages the annular shoulder or lip 28 of the
sleeve.
Instead of having a sleeve separate from the tubular membrane 18,
the lower end of the tubular member may be internally threaded and
provided with an inwardly extending annular lip or shoulder above
the threads so that it can be screwed to the threaded neck of the
lower container. The tubular member 18 has a reduced externally
threaded neck 29.
As can be seen in FIG. 2, the lower container 12 forms a
compartment 14 which is separated from the upper compartment 20 in
the upper container 18 and each of the containers or compartments,
namely, the lower container and the upper container may be filled
with an appropriate material. For example, if used for a hair
coloring preparation the lower container may have the coloring
material and the upper container may be filled with a peroxide.
A cap 30 which is internally threaded as at 31 is adapted to be
secured to the threaded neck 29 of the upper container and said cap
is provided with a central annular opening 32, with an annular
depending sleeve 34 extending into the interior of the upper
compartment.
A plunger generally designated by the numeral 36 is mounted for
reciprocal movement in the cap 30. The plunger 36 has a lower
tubular body 38, a reduced tubular portion 40 and a tapered tip or
spout 42. A shoulder 44 is provided between the tubular body 38 and
the tubular portion 40. The tubular body 38 of the plunger is
provided with a plurality of spaced openings 46. Integrally formed
with the plunger and at the bottom thereof is an annular cutter
ring or member 48 of a greater diameter than the tubular body 38.
The bottom edge of the cutter ring has a knife edge 50 and the
bottom edge slopes or inclines downwardly from the narrowed portion
51 to the widest portion 52. It will be understood that the cutter
may be of any other shape or construction as long as it is capable
of puncturing the partition 22. The tapered tip 42 of the spout may
be molded to form a closed end 43 which is snipped off when ready
for use.
A truncated cone-shaped cap 53 may be positioned over the end of
the spout and same may be held on the spout frictionally, or it may
be internally threaded with respect to said spout. The cap 53 is
used to close the spout opening after the tip 43 has been snipped
off.
The plunger 36 is positioned so that the tubular portion 40 is
slidably received in the sleeve 34 of the cap 30 and the plunger is
manually operated by moving it inwardly. When the plunger is moved
inwardly relative to the partition or separating membrane 22, the
cutter member 48 will when in contact with the partition cut,
rupture or puncture the partition membrane, as shown in FIG. 2, to
provide a communicating passageway between the lower compartment 14
and the upper compartment 20 so that the material contained in the
two separate compartments will come together and comix. When the
dispenser is inverted, such as when the material is to be applied
to the hair, the mixed material will pass through the openings 46
in the plunger and through the single spout 42.
To prevent the plunger from being pushed inwardly while the unit is
being shipped, a snap-on clip 54 is positioned around the tubular
portion 40 of the plunger extending above the top of the cap 30 and
the clip will engage the bottom of the cone-shaped cap. While said
snap-on clip is thus secured to the plunger, the plunger will be
prevented from being moved inwardly relative to the container.
After the clip is manually removed the plunger may then be pushed
downwardly into the container for the purpose described. The
shoulder 44 limits the upward withdrawal of the plunger.
While the drawings illustrate two separate compartments with a
single partition therebetween, it will be understood that an
identically constructed unit may be formed with three or more
compartments, with each of said compartments containing a different
material and each of said compartments being separated by a
partition similar to the partition previously described so that
when the plunger is moved inwardly the cutter on the plunger will
puncture the two or more partitions so that all of said
compartments will be in communication with each other and the
material will flow from one compartment into the other. Thus, the
invention here is intended to cover a multiplicity of separate
compartments and is not limited to two compartments.
The embodiment shown in FIGS. 6 through 9, generally designated at
60, will now be described. It is generally similar to that
previously described, however, the unit forming the upper
compartment has a bellows which when manually compressed will move
the plunger inwardly to perform the cutting operation. In this
embodiment the lower container 61 has an externally threaded neck
62 and same may be formed of glass or the like. It forms
compartment 63. The upper compartment 64 is formed of a tubular
member 65, formed preferably of the polyethylene material, with the
bottom thereof open and having a reduced annular externally
threaded portion 66 of the same diameter as the neck 62. A
diaphragm or partition 68 is positioned between the two with a
washer 69 therebetween. An internally threaded coupling sleeve 70
connects the bottom with the top container. The upper portion of
the upper compartment has a bellowed portion 72 which terminates in
an externally threaded neck 74. An internally threaded cap 76 is
adapted to be secured to the neck 74 and the cap has a central
opening 78.
The plunger generally indicated at 80 has a tubular body 82 with an
inclined lower cutting edge 84, similar to that previously
described. The plunger has openings 83 and a truncated cone-shaped
tip 86 which forms the spout. The tip thereof is closed as at 87 to
be snipped off, with a cap 88 to be positioned thereon to close the
spout opening. The plunger is positioned inside the neck 74 and is
held to the neck of the cap with the shoulder 89 of the plunger
against the horizontal wall of the cap. The spout 86 of the plunger
extends through the cap opening 78 and outwardly thereof.
Normally, during shipment and until used, the unit is as shown in
FIG. 6, with the plunger in retracted position and the bellows 72
extended. By positioning a collar or tubular member 90 around the
bellows to hug the bellows, the bellows will be prevented from
being pressed inwardly during shipment. The tubular member 90 will
rest on the shoulder 91 of the upper container 65 and should extend
slightly above the cap 88. However, when the collar is removed
therefrom the bellows may be compressed, as shown in FIG. 7, to
cause the cutting edge 64 of the plunger to rupture the diaphragm
68 for the purpose previously described. Additional compartments
may be provided as previously described.
