Technical Field of the Invention
[0001] The present invention relates to a cartridge system according to the preamble of
claim 1 for simultaneously dispensing two component materials.
Background Art
[0003] Dual dispenser cartridges for two-component reactive material systems, such as epoxy
glue, molding compounds, foams and sealants are known and typically have a pair of
parallel conjoined syringes, i.e., having a pair of barrels; for independently storing
two different components and a corresponding pair of conjoined plungers that are slidable
in the barrels in piston fashion. When the plungers are simultaneously pushed into
the pair of parallel conjoined barrels, the two different materials of the two-component
system are simultaneously and proportionally ejected at the outlet end of the syringe
pair. In simple, non-commercial systems, the ejecta is most likely to be deposited
upon a surface whereon it can be mixed, e.g., by a paddle. Commercial systems typically
utilize a nozzle which is threaded onto the outlet and which may include a static
mixer. In either case, it remains an objective to improve the simplicity and economy
of design of the cartridge, to provide an effective cap that can be removed and replaced
to store unused materials and to maintain the separation of chemically reactive components
until they are dispensed for their intended purpose, i.e., to prevent cross-contamination.
Cross-contamination is known to result in the unintentional chemical reaction between
the reactive components resulting in plugging of the cartridge and spoilage of the
contents.
Disclosure of the Invention
[0004] The problems and disadvantages associated with the conventional techniques and devices
utilized to store and dispense two-component reactive material systems are overcome
by the present invention with a cartridge system according to claim 1.

Best Mode for Carrying Out the Invention
[0006] FIGS. 1 and 2 show a dual cylinder cartridge 10 having a pair of cylinders 12, 14
for storing two different components, such as the two reactive compounds used in epoxy
glue or molding compound. A pair of plungers 16, 18 slide within the cylinders 12,
14 for ejecting the contents through a static mixer (See FIG. 9). Alternatively, the
contents may be ejected directly onto a substrate in certain simple, non-commercial
applications. The plungers 16, 18 are mechanically conjoined and/or are simultaneously,
activated, e.g., as shown in FIG. 9 and described below. In simple domestic glue dispensers,
the plungers 16, 18 may be conjoined by a common push pad. While two, cylindrical
cylinders 12, 14 are shown in FIG. 1, a greater number of cylinders could be employed
and they could have a non-circular cross-sectional shape, e.g., octagonal or hexagonal,
all within the intended scope of the present invention. The cylinders 12, 14 are mechanically
joined at the top by a bridge plate 20 from which extends a common outlet 22. A lower
bridging tab 24 mechanically connects the cylinders 12, 14 at the end distal to the
outlet 22. The outlet 22 has a cap 26 which maintains an air tight seal to preserve
the contents of both cylinders 12, 14 until the cap 26 is removed to expel the contents.
The cap 26 has indicia 28, 30 indicating orientation relative to the contents of the
cylinders 12, 14, which are also signified by matching indicia 32, 34 on the bridge
plate 20. In this manner, the cap portions (to be shown and described below) that
contact the components stored in cylinders 12, 14, respectively, will not cross-contaminate
any remaining compound to be stored after ejecting when the cap 26 is replaced, i.e.,
by reversing its original orientation. The outlet 22 has threads 36 to facilitate
threading a specialized nozzle (see FIG. 9) thereon, e.g., one having an elongated
conical shape to permit applying the compound(s) dispensed into a hard-to-reach area.
As noted above, a nozzle containing a static mixer can also be employed. FIG. 2 shows
that the cap 26 may be provided with indicia 38 on the side thereof matching that
provided on the top at 30. The same type of indicia 38 may be provided on the opposite
side of the cap 26 (but bearing a similarity to indicia 28).
[0007] FIG. 3 shows that the outlet 22 is divided into two separate conduits or passageways
54, 56 by a divider wall 55 (see FIG. 4) to permit the compounds separately stored
in cylinders 12, 14 to be dispensed through the outlet 22 without mixing. The divider
wall 55 may be provided with an internal hollow 40 (see FIG. 3) to decrease plastics
usage and to decrease material stress and distortion associated with the injection
molding process. The separation of the reactive components is also maintained by divider
wall extension 42 that extends from the dispenser end 44 of the outlet 22. Accordingly,
even after the reactive compounds are ejected out of the outlet 22, they are kept
separated. As noted above, commercial applications frequently utilize a nozzle/static
mixer 394, 395 (See FIG. 9) that is threadedly received and retained on the outlet
22. The divider wall 42 can be formed to partially insert into the nozzle/static mixer
394, 395 to insure that no mixing of components occurs prior to the entrance of the
compounds into the nozzle/static mixer 394, 395. The cap 26 has a pair of separate
nozzle plugs 46, 48 that are inserted into separate outlet apertures, e.g., 168, 170
(see FIG. 7) as will be seen and described below. The cap 26 also has an abutment
flange 50 to limit the insertion depth of the plugs 46, 48. A grasping orifice 52
is provided on the cap 26 to permit the insertion of a screwdriver blade or another
tool to provide leverage for breaking the cap 26 away from its integral mounting on
the outlet 22 to eject the stored compounds.
[0008] FIGS. 4 and 5 show that the outlet 22 has two separate passageways 54, 56 communicating
with cylinders 12, 14, respectively. The passageways 54, 56 are plugged by plugs 46,
48, which are still connected to the outlet 22, i.e., the cap 26 has not yet been
removed. FIG. 5 shows that the plugs 46, 48 (48 is shown) are connected to the dispenser
end 44 of the outlet 22 by a frangible bridge 58 extending between the outlet dispenser
end 44 and the plug 48. To release the compound(s) contained within the cylinders
12, 14, the cap 26 is bent back and/or away from the outlet 22 in order to break the
frangible bridge 58 and remove the plugs 46, 48 from their position blocking the passageways
54, 56. The plugs 46, 48 have a taper 60 on their peripheral edge to assist in inserting
them back into the passageways 54, 56 to reseal the dispenser 10 in the manner shown
in FIG. 6. Each of the plugs 46, 48 have an enlarged portion 62 terminating in a ledge
64. When the plugs 46, 48 are inserted and pressed into the passageways 54, 56 to
reseal the cartridge 10, the remnants of the frangible bridge 58 extending from the
dispenser end 44, clip over ledge 64, holding the cap 26 in position and increasing
the tightness of the seal made by the cap 26 to increase the length of time that the
compounds stored in the cartridge can be kept without degradation.
[0009] FIG. 6 shows the cap 26 positioned on the outlet 22 with the plugs 46, 48 extending
into and sealing the passageways 54, 56. The cartridge 10 may be injection molded
from polymers such as polypropylene or polyamide. It should be appreciated that the
cap 26 shown in the foregoing figures and described above, works in conjunction with
the divider wall extension 42, viz., by bridging thereover. More particularly, a central
hollow 66 disposed between the plugs 46, 48 accommodates the divider wall extension
42, both before and after removal and replacement of the cap 26.
[0010] FIG. 7 shows a first alternative embodiment of the present invention. In describing
this alternative embodiment and subsequent alternative embodiments, the same reference
numbers as were used above to refer to elements of the above-described embodiment
shall be used but incremented by 100, 200, etc. to describe features having the same
or similar form and function, unless otherwise noted. In FIG. 7, the passageways 154,
156 terminate in outlet apertures 168, 170, respectively having unique shapes relative
to one another. The plugs 146, 148 have complementary shapes in order to be received
within corresponding outlet apertures, 168, 170. In this manner, the cap 126 can only
be replaced on the cartridge outlet 122 in one orientation, thereby preventing cross-contamination
between the contents issuing from passageways 154, 156, respectively. The apertures
168, 170 have different cross-sectional areas, which would be particularly suitable
for a two-component system wherein the stoichiometric ratio of the first component
to the second is not 1:1, e.g., 2:1, 3:1, etc. While the apertures 168, 170 shown
have different cross-sectional areas, this is not required. For example, the present
invention could be practiced with apertures 168, 170 having a different shape but
the same cross-sectional area, e.g., circular and triangularly shaped apertures 168,
170.
[0011] FIG. 8a shows an outlet 222 with orientation features that allow the apertures 268,
270 to be the same shape and still constrain cap 226 replacement orientation , i.e.,
such that the cap 226 only inserts into the outlet 222 in one selected orientation
to prevent cross-contamination. More particularly, the cap 226 has a depending orientation
tab 272 that is accommodated in a mating notch 274 in the divider wall 242, but only
in the permissible resealing orientation. (Note that one of the plugs, viz., 248 in
FIGS. 8a and 8b and 246 in FIG. 8c , has been cut away to permit visualization of
the interaction between the tab 272 and the notch 274.) As shown in FIG. 8b, the notch
274 accommodates the tab 272 permitting the plug 246 to enter and reseal outlet aperture
268. The alternative orientation of the cap 226 relative to the outlet 222 is shown
in FIG. 8c wherein the interference between the divider wall 242 (opposite to the
notch 274) and the tab 272 prevents plug 248 from entering outlet aperture 268. Because
correct orientation is assured by the tab 272 and divider wall 242 with notch 274,
the apertures 268, 270 may either be the same shape and dimensions or of different
shapes and dimensions, as desired.
[0012] FIG. 9 shows a dispenser gun 376 for ejecting the compounds contained in a two-component
cartridge 310 and which has a cartridge tray 377 affixed to an actuator 378. The actuator
378 is of conventional design, such as might be encountered in a common caulking gun
having a friction or ratchet advance mechanism. The degree of advancement of the actuator
mechanism is controlled by squeezing handles 379, 380, one or both of which moves
relative to the other in a conventional manner. In addition to purely mechanical advance
mechanisms, the present invention would work equally well with a hydraulic, compressed
air or electromagnetic advance mechanism, e.g., as might be encountered on a production
line. The ejector gun 376 has at least one actuator rod 381 and a piston rod 382,
383 for each cylinder 312, 314, respectively. Alternatively, the actuator rod 381
can serve as a piston rod, e,g,. replacing 382.
[0013] The actuator rod 381 and piston rods 382, 383 are conjoined at one end by a bridge
bar 384 to which a pull knob 385 is attached, such that all rods 381, 382, 383 move
simultaneously as an assembly. A piston plate 386 is attached to piston rod 383 at
the end thereof proximate to the cartridge tray 377. A second, larger piston plate
387 is affixed to the end of piston rod 382 and actuator rod 381. In this manner,
the ejector gun 376 can be utilized for cartridges having cylinders 312, 314 of the
same or different diameters. As depicted in FIG. 9, the cylinders 312, 314 are the
same diameter but they could be of different diameters for the purpose of dispensing
reactive compounds in other than a 1:1 ratio. In that instance, the larger of the
cylinders 312, 314 can be positioned proximate the larger piston plate 387, with the
smaller of the cylinders 312, 314 positioned proximate piston plate 386. The present
invention does not require that the pistons 386, 387 have different dimensions, i.e.,
they may have the same dimensions.
[0014] The tray 377 is held to the actuator portion 378 by a plurality of fasteners 389,
by welding, gluing or other conventional means. Distal to the actuator 378, the tray
has an end plate 390 with a cartridge docking cutout 391 for slideably receiving and
embracing the cartridge 310 at the base of the outlet 322. A cap removal tab 392 extends
from an upper corner of the end plate 390 and has dimensions approximating the internal
dimensions of the grasping orifice 352 provided in the cap 326 (See FIG. 3, reference
number 52 for an enlarged view of a grasping orifice.) Given this relationship, the
cap removal tab 392 can be inserted into the grasping orifice 352 to exert a twisting
force to snap the cap 326 off the outlet 322 to open the cartridge 310. The removal
tab 392 may be dimensioned relative to the grasping orifice 352 to have a friction
fit therein such that cap 326 can be left on the removal tab 392 while the cartridge
310 is in use. In this manner, the cap 326 is not lost or subjected to contamination
while the cartridge 310 is in use and may be readily retrieved for resealing the cartridge
when ejecting is completed.
[0015] A nozzle tip orifice 393 may be incorporated in the end plate 390 for aiding in the
removal of portions of the nozzle tip. More particularly, a nozzle 394, which may
incorporate a static mixing element 395 (in dashed lines) is provided with a snap-off
tip 396. The tip 396 may be snapped off to control the outlet aperture size of the
nozzle 394, That is, the tip 396 has a predetermined outlet aperture size. When the
tip 396 is snapped off, a larger diameter outlet aperture results. The nozzle tip
orifice 393 accommodates the tip 396 therein and provides leverage over the tip 396
to aid in snapping it off. A cartridge support 397 extends up from the bottom of the
tray 377 and inserts between the cylinders 312, 314 to prevent lateral motion of the
cartridge 310 to retain the cartridge in alignment with the motion of the piston plates
386, 387 to maximize the transfer of force from piston plates 386, 387 to expel the
compound from the cartridge 310.
[0016] It should be understood that the embodiments described herein are merely exemplary
and that a person skilled in the art may make many variations and modifications without
departing from the scope of the invention as defined in the appended claims. Accordingly,
all such variations and modifications are intended to be included within the scope
