Description
RELATED APPLICATIONS
[0001] This application (Attorney's Ref. No. P217844) claims
benefit of U.S. Provisional Application Ser. Nos. 61/793,315,
61/801,537, and 61/800,653, all filed Mar. 15, 2013, the contents
of which are incorporated herein by reference.
TECHNICAL FIELD
[0002] The present invention is adapted to facilitate the use of
dispensing systems employing an aerosol system with different types
of actuator assemblies to dispense coatings such as texture
material and may be configured to protect the valve of an aerosol
system manufactured, shipped, and sold without an outlet
assembly.
BACKGROUND
[0003] Interior wall surfaces of a structure are typically formed
by sheets of drywall material secured to the framing of the
structure. After the drywall material is secured to the framing,
the seams between adjacent sheets are typically taped and mudded
and sanded flat. At that point, a primer is typically applied to
the taped and mudded sheets of drywall material. A finish coat of
paint may be applied directly to the primer, but a texture coat may
be applied to the primer before the finish coat is applied.
Typically, a second primer coat is applied to the texture material.
If used, a texture coat forms a bumpy, irregular surface that hides
irregular mudding, taping, and sanding and creates an aesthetically
pleasing textured look to the finished wall surface.
[0004] When an interior wall is damaged (e.g., scratch, hole,
etc.), it is desirable that the wall be repaired such that the
repaired portion substantially matches wall surrounding the
repaired portion. The present invention is of particular importance
when used to apply coatings in the context of repairing a wall
surface.
SUMMARY
[0005] The present invention may be embodied as a dispenser for
aerosol material, comprising an aerosol assembly, an adapter
assembly, and an actuator assembly. The aerosol assembly comprises
a valve structure and defines a rim structure that extends at least
around the valve structure. The adapter assembly comprises a fixed
member adapted to be attached to the rim structure and a removable
member adapted to detachably attached to the fixed member. The
actuator assembly is adapted to be detachably attached to the fixed
member. The dispenser is in a first configuration when the fixed
member is attached to the rim structure and the removable member is
detachably attached to the fixed member. The dispenser is in a
second configuration when the fixed member is attached to the rim
structure and the actuator assembly is detachably attached to the
fixed member. The removable member substantially covers the valve
structure when the dispenser is in the first configuration. The
actuator assembly engages the valve assembly to allow product to be
dispensed from the aerosol assembly when the dispenser is in the
second configuration.
[0006] The present invention may also be embodied as a method of
dispensing aerosol material, comprising the following steps. An
aerosol assembly is provided. The aerosol assembly comprises a
valve structure and defines a rim structure that extends at least
around the valve structure. An adapter assembly is provided. The
adapter assembly comprises a fixed member adapted to be attached to
the rim structure and a removable member adapted to detachably
attached to the fixed member. An actuator assembly adapted to be
detachably attached to the fixed member is provided. The dispenser
is arranged in a first configuration by attaching the fixed member
to the rim structure and the removable member to the fixed member
such that the removable member substantially covers the valve
structure. The dispenser is arranged in a second configuration by
attaching the fixed member to the rim structure and the actuator
assembly to the fixed member such that the actuator assembly
engages the valve assembly. The actuator assembly is operated to
dispense product from the aerosol assembly when the dispenser is in
the second configuration.

DETAILED DESCRIPTION
[0042] Referring initially to FIGS. 1 and 2 of the drawing,
depicted therein is an example of an adapter system 20 constructed
in accordance with, and embodying, the principles of the present
invention. The example adapter system 20 is used with an aerosol
system 22. The example aerosol system 22 is or may be conventional
and will be explained herein only to that extent necessary for a
complete understanding of the present invention.
[0043] The example aerosol system 22 comprises an aerosol container
30 and a valve cup 32. The valve cup 32 is mounted to the container
30 at a rim structure 40 formed by a container crimped portion 42
and a valve cup crimped portion 44. The example aerosol assembly 22
further comprises a valve assembly 50 and a dip tube 52. The
example valve assembly 50 comprises a valve housing 60, a valve
seat member 62, a valve member 64, and a valve spring 66. The valve
member 64 defines a valve member cavity 70 and a valve member
projection 72 that extends into the valve cavity 70.
[0044] The example valve cup 32 defines an exterior surface 80
having a mouth portion 82, a throat portion 84, and an undercut
portion 86. A diameter of the mouth portion 82 is smaller than a
diameter of the throat portion 84. The undercut portion 86 extends
between the mouth portion 82 and the throat portion 84 and has a
vector component that is substantially perpendicular to an axis A
defined by the container 30 when the valve cup 32 is joined to the
aerosol container 30 by the rim structure 40. The exterior surface
80 of the valve cup 32 further defines an outermost portion 90 and
an end portion 92. The diameter of the outermost portion 90 is
larger than that of the end portion 92, so the end portion 92 also
has a vector component that is also substantially perpendicular to
the container axis A when the valve cup 32 is joined to the aerosol
container 30.
[0045] The aerosol system 22 thus defines certain components and
features that will be accommodated by the various examples of the
adapter system 20 of the present invention as described herein. To
the contrary, the example adapter system 20 of the present
invention facilitates the use of aerosol systems of many sizes,
shapes, and configurations. In that context, the example aerosol
system 22 will not be described again in detail in connection with
other examples of the aerosol dispensing system 20 of the present
invention.
[0046] Turning again back to FIGS. 1 and 2, it can be seen that the
example adapter system 20 comprises an example adapter assembly 120
comprising a fixed member 122 and a removable member 124. The fixed
member 122 defines a plug portion 130 and a perimeter portion 132.
The example plug portion 130 defines an outer surface 140 and an
inner surface 142. The example inner surface 142 is threaded to
define a transition surface as will be described in further detail
below.
[0047] The example outer surface 140 of the plug portion 130
defines a proximal portion 150, a distal portion 152, and a
transition portion 154. The perimeter portion 132 of the fixed
member 122 defines an engaging surface 160 having a widest portion
162 and a tip portion 164.
[0048] The example removable member 124 defines a base portion 190
and an extension portion 192. The extension portion 192 defines a
threaded surface 194.
[0049] The example adapter assembly 120 is assembled and used as
follows. The fixed member 122 is displaced until the plug portion
130 engages the valve cup exterior surface 80 and the perimeter
portion 132 engages the rim structure 40. In particular, the distal
portion 152 of the outer surface 140 of the plug portion 130 is
forced past a restriction formed by the mouth portion 82 of the
valve cup exterior surface 80. At the same time, the tip portion
164 of the engaging surface 160 on the perimeter portion 132 is
forced past the outermost portion 90 of the valve cup exterior
surface 80. When the distal portion 152 passes the mouth portion 82
and the tip portion 164 passes the outermost portion 90, the fixed
member 122 snaps into place on the aerosol system 22 in an attached
position as shown in FIGS. 1 and 2. In this attached position, the
transition portion 154 engages the undercut portion 86 and the tip
portion 164 engages the end portion 92 to positively lock the fixed
member 122 into the attached position.
[0050] With the fixed member 122 in the attached position, the
removable member 124 may be detachably attached to the fixed member
122 using internal threads formed on the inner or transition
surface 142 on the fixed member 122 and mating external threads on
the threaded surface 194 of the extension portion 192 of the
removable member 124. When the removable member 124 is attached to
the fixed member 122 as shown in FIG. 1, access to the valve member
cavity 70 and valve member projection 72 is restricted. When the
removable member 124 is detached from the fixed member 122 as shown
in FIG. 2, access to the valve member cavity 70 and valve member
projection 72 is allowed.
[0051] Turning now to FIGS. 3 and 4, depicted therein is an example
adapter assembly 220 that may be used to form an example adapter
system of the present invention. The example adapter assembly 220
comprises a fixed member 222 and a removable member 224. The fixed
member 222 defines a plug portion 230, a perimeter portion 232, and
a transition portion 234. The example plug portion 230 defines an
outer surface 240.
[0052] The example outer surface 240 of the plug portion 230
defines a proximal portion 250, a distal portion 252, and a
transition portion 254. The perimeter portion 232 of the fixed
member 122 defines an engaging surface 260 having a widest portion
262 and a tip portion 264. The transition portion 234 of the fixed
member 222 defines a transition surface 270.
[0053] The example removable member 224 defines a base portion 290
and an extension portion 292. The extension portion 292 defines a
threaded surface 294.
[0054] The example adapter assembly 220 is assembled and used as
follows. The fixed member 222 is displaced until the plug portion
230 engages the valve cup exterior surface 80 and the perimeter
portion 232 engages the rim structure 40. In particular, the distal
portion 252 of the outer surface 240 of the plug portion 230 is
forced past a restriction formed by the mouth portion 82 of the
valve cup exterior surface 80. At the same time, the tip portion
264 of the engaging surface 260 on the perimeter portion 232 is
forced past the outermost portion 90 of the valve cup exterior
surface 80. When the distal portion 252 passes the mouth portion 82
and the tip portion 264 passes the outermost portion 90, the fixed
member 222 snaps into place on the aerosol system 22 in an attached
position as shown in FIGS. 3 and 4. In this attached position, the
transition portion 254 engages the undercut portion 86 and the tip
portion 264 engages the end portion 92 to positively lock the fixed
member 222 into the attached position.
[0055] With the fixed member 222 in the attached position, the
removable member 224 may be detachably attached to the fixed member
using external threads formed on the transition surface 270 on the
fixed member 222 and mating internal threads on the threaded
surface 294 of the extension portion 292 of the removable member
224. When the removable member 224 is attached to the fixed member
222 as shown in FIG. 3, access to the valve member cavity 70 and
valve member projection 72 is restricted. When the removable member
224 is detached from the fixed member 222 as shown in FIG. 4,
access to the valve member cavity 70 and valve member projection 72
is allowed.
[0056] Turning now to FIGS. 5 and 6, depicted therein is an example
adapter assembly 320 that may be used to form an example adapter
system of the present invention. The example adapter assembly 320
comprises a fixed member 322 and a removable member 324. The fixed
member 322 defines a plug portion 330, a perimeter portion 332, and
a transition portion 334. The example plug portion 330 defines an
outer surface 340.
[0057] The example outer surface 340 of the plug portion 330
defines a proximal portion 350, a distal portion 352, and a
transition portion 354. The perimeter portion 332 of the fixed
member 322 defines an engaging surface 360 having a widest portion
362 and a tip portion 364.
[0058] The transition portion 334 of the fixed member 322 defines a
transition opening 370. As perhaps best shown in FIG. 8, one or
more lock bumps 372 are formed on the transition portion 334, and
one or more key notches 374 are formed on opposing sides of the
transition opening 370. Locking portions 376 of the transition
portion 334 of the fixed member 322 are formed between each of the
key notches 374.
[0059] The example removable member 324 defines a base portion 380
and an extension portion 382. A locking lip 390 is formed on the
extension portion 382 for each of the key notches 374. One or more
locking recesses 392 are formed on the extension portion 382 as
shown in FIG. 7.
[0060] The example adapter assembly 320 is assembled and used as
follows. The fixed member 322 is displaced until the plug portion
330 engages the valve cup exterior surface 80 and the perimeter
portion 332 engages the rim structure 40. In particular, the distal
portion 352 of the outer surface 340 of the plug portion 330 is
forced past a restriction formed by the mouth portion 82 of the
valve cup exterior surface 80. At the same time, the tip portion
364 of the engaging surface 360 on the perimeter portion 332 is
forced past the outermost portion 90 of the valve cup exterior
surface 80. When the distal portion 352 passes the mouth portion 82
and the tip portion 364 passes the outermost portion 90, the fixed
member 322 snaps into place on the aerosol system 22 in an attached
position as shown in FIGS. 5 and 6. In this attached position, the
transition portion 354 engages the undercut portion 86 and the tip
portion 364 engages the end portion 92 to positively lock the fixed
member 322 into the attached position.
[0061] With the fixed member 322 in the attached position, the
removable member 324 may be detachably attached to the fixed member
using a latch system formed by the locking lip 390 and the locking
portions 376. In particular, the removable member is oriented such
that the locking lip(s) 390 are aligned with the key notch(es) 374
and displaced such that the locking lip(s) 390 pass through the
transition opening 370. The removable member 324 is then rotated
such that the locking lip(s) 390 are arranged under the locking
portion 376. The locking recesses 392 receive the locking
projections 372 to inhibit inadvertent rotation of the removable
member 324 relative to the fixed member 322. The removable member
324 may be detached by reversing this process.
[0062] When the removable member 324 is attached to the fixed
member 322 as shown in FIG. 5, access to the valve member cavity 70
and valve member projection 72 is restricted. When the removable
member 324 is detached from the fixed member 322 as shown in FIG.
6, access to the valve member cavity 70 and valve member projection
72 is allowed.
[0063] Turning now to FIGS. 9 and 10 of the drawing, depicted
therein is an embodiment 420a of an example actuator assembly 420
that is adapted to be connected to the aerosol system 22 using the
example fixed member 122 described above. The example actuator
member 420 comprises a handle housing 422, an outlet member 424, a
trigger member 426, and an outlet assembly 428. Optionally, the
outlet assembly 428 may define an adjustable orifice. The example
trigger member 426 comprises a finger portion 430 and a trigger
projection 432. The trigger member 426 is rotatably connected to
the handle housing 422 at an axis 434. Displacing the finger
portion 430 in a first direction causes the trigger member 426 to
rotate about the axis 434 such that the trigger projection 432
displaces the outlet member 424 downwardly relative to the handle
housing 422.
[0064] The example handle housing 422 defines an interface portion
440 comprising a threaded surface 442. The example interface
portion 440 is below the handle housing 422 during normal use of
this example actuator assembly 420a. The threaded surface 442 is
adapted to mate with the inner transition surface 142 of the
example fixed member 122 to detachably attach the example actuator
assembly 420a to the aerosol system 22 such that the outlet member
424 engages the valve assembly 50. The aerosol system 22 is
supported below the example actuator assembly 420a during normal
use. So attached, downward movement of the trigger projection 432
caused by displacement of the finger portion 430 causes the outlet
member 424 to move downward, place the valve assembly 50 in its
open configuration, and dispense contained material through the
outlet assembly 428.
[0065] FIG. 11 illustrates an embodiment 420b of the example
actuator assembly 420 that is adapted to be connected to the
aerosol system 22 using the example fixed member 222 described
above. In the embodiment 420b, the example handle housing 422
defines an interface portion 450 comprising a threaded surface 452.
The threaded surface 452 is adapted to mate with the transition
surface 270 of the example fixed member 222 to detachably attach
the actuator assembly 420b to the aerosol system 22 such that the
outlet member 424 engages the valve assembly 50. So attached,
displacement of the finger portion 430 causes material to be
dispensed through the outlet assembly 428.
[0066] FIG. 12 illustrates an embodiment 420c of the example
actuator assembly 420 that is adapted to be connected to the
aerosol system 22 using the example fixed member 322 described
above. In the embodiment 420c, the example handle housing 422
defines an interface portion 460 comprising a locking lip 462 and
one or more locking recesses 464. The locking lip 462 and locking
recesses 464 are adapted to engage the locking portions 376 of the
example fixed member 322 to detachably attach the actuator assembly
420c to the aerosol system 22 such that the outlet member 424
engages the valve assembly 50. So attached, displacement of the
finger portion 430 causes material to be dispensed through the
outlet assembly 428.
[0067] Turning now to FIG. 13, depicted therein is an example
actuator assembly 520 that is adapted to be connected to the
aerosol system 22 using the example fixed member 122 described
above. The example actuator assembly 520 comprises a handle housing
522, an outlet member 524, a trigger member 526, and an outlet
assembly 528. Optionally, the outlet assembly 528 may define an
adjustable orifice. The example trigger member 526 comprises a
finger portion 530 and a trigger projection 532. The trigger member
526 is pivotably connected to the handle housing 522 at a hinge
point 534. Displacing the finger portion 530 in a first direction
causes the trigger member 526 to pivot about the hinge point such
that the trigger projection 532 displaces the outlet member 524
upwards relative to the handle housing 522.
[0068] The example handle housing 522 defines an interface portion
522a comprising a threaded surface 442. The example interface
portion 522a is above the handle housing 522 during normal use of
this example actuator assembly 520. The example interface portion
522a is similar to the interface portion 440 described above, and a
threaded surface 442 defined by the interface portion 522a is
adapted to mate with the inner transition surface 142 of the
example fixed member 122 to detachably attach the example actuator
assembly 520 to the aerosol system 22 such that the outlet member
524 engages the valve assembly 50. The aerosol system 22 is
supported above by the example actuator assembly 520 during normal
use. So attached, upward movement of the trigger projection 532
caused by displacement of the finger portion 530 causes the outlet
member 524 to move upward, place the valve assembly 50 in its open
configuration, and dispense contained material through the outlet
assembly 528.
[0069] While not explicitly shown in the interests of brevity and
clarity, the example actuator assembly 520 may be adapted to be
connected to the aerosol system 22 using the interface portions 450
or 460 and the example fixed members 222 and 322 described
above.
[0070] Turning now to FIG. 14, depicted therein is an example
actuator assembly 550 that is adapted to be connected to the
aerosol system 22 using the example fixed member 122 described
above. The example actuator member 550 comprises a handle housing
552, an outlet member 554, a trigger member 556, and an outlet
assembly 558. Optionally, the outlet assembly 558 may define an
adjustable orifice. The example trigger member 556 comprises a
finger portion 560 and a trigger projection 562. The trigger member
556 is pivotably connected to the handle housing 552 at a hinge
point 564. Displacing the finger portion 560 in a first direction
causes the trigger member 556 to pivot about the hinge point such
that the trigger projection 562 displaces the outlet member 554
rearwards relative to the handle housing 552.
[0071] The example handle housing 552 defines an interface portion
552a that faces behind the handle housing 552 during normal use of
this example actuator assembly 550. The example interface portion
552a may be the same as the example interface portions 440
described above. The example interface portion 552a thus defines
the threaded surface 442 adapted to mate with the inner transition
surface 142 of the example fixed member 122 to detachably attach
the example actuator assembly 550 to the aerosol system 22 such
that the outlet member 554 engages the valve assembly 50. The
aerosol system 22 is supported behind the example actuator assembly
550 during normal use. So attached, rearward movement of the
trigger projection 562 caused by displacement of the finger portion
560 causes the outlet member 554 to move rearward, place the valve
assembly 50 in its open configuration, and dispense contained
material through the outlet assembly 558.
[0072] While not explicitly shown in the interests of brevity and
clarity, the example actuator assembly 550 may be adapted to be
connected to the aerosol system 22 using the interface portions 450
or 460 and the example fixed members 222 and 322 described
above.
[0073] Turning now to FIGS. 15 and 16, depicted therein is an
example actuator assembly 570 that is adapted to be connected to
the aerosol system 22 using the example fixed member 122 described
above. The example actuator member 570 comprises a handle housing
572, an outlet member 574, a trigger member 576, and an outlet
assembly 578. Optionally, the outlet assembly 578 may define an
adjustable orifice. The example trigger member 576 comprises a
finger portion 580 and a trigger projection 582. The trigger member
576 is supported for sliding, linear, front and back movement on
the handle housing 572 by rails 584. A cam surface 586 is formed on
top of the example outlet member 574. Displacing the finger portion
580 in a first direction causes the trigger member 576 to slide
rearwardly along the rails 584 such that the trigger projection 582
acts on the cam surface 586. The cam surface 586 is configured to
translate rearward linear movement of the trigger projection 582
into downward movement of the outlet member 574.
[0074] The example handle housing 572 defines an interface portion
572a configured to face below the handle housing 572 during normal
use of this example actuator assembly 570. The example interface
portion 572a is similar to the interface portion 440 described
above and thus defines a threaded surface 442. The threaded surface
442 is adapted to mate with the inner transition surface 142 of the
example fixed member 122 to detachably attach the example actuator
assembly 570 to the aerosol system 22 such that the outlet member
574 engages the valve assembly 50. The aerosol system 22 is
supported below the example actuator assembly 570 during normal
use. So attached, rearward movement of the trigger projection 582
caused by displacement of the finger portion 580 causes the outlet
member 574 to move downward, place the valve assembly 50 in its
open configuration, and dispense contained material through the
outlet assembly 578.
[0075] While not explicitly shown in the interests of brevity and
clarity, the example actuator assembly 570 may be adapted to be
connected to the aerosol system 22 using the interface portions 450
or 460 and the example fixed members 222 and 322 described
above.
[0076] Turning now to FIGS. 17 and 18, depicted therein is an
example actuator assembly 620 that is adapted to be connected to
the aerosol system 22 using the example fixed member 122 described
above. The example actuator member 620 comprises a handle housing
622, an outlet member 624, a trigger assembly 626, and an outlet
assembly 628. Optionally, the outlet assembly 628 may define an
adjustable orifice. The example trigger assembly 626 comprises a
trigger member 630 and a trigger link 632. The trigger member 630
is supported for pivoting movement relative to the handle housing
622 about a first pivot axis 634. The trigger link 632 is supported
for pivoting movement relative to the handle housing 622 about a
second pivot axis 636. The trigger member 630 and trigger link 632
are further operatively connected to allow relative rotation about
a moving pivot axis 638. Rotating the trigger member 630 in a
clockwise direction causes the trigger member 626 to rotate the
trigger link 632 downwardly in a counterclockwise direction such
that the trigger link 632 displaces the outlet member 624 downward
relative to the handle housing 622.
[0077] The example handle housing 622 defines an interface portion
622a configured to face below the handle housing 622 during normal
use of this example actuator assembly 620. The example interface
portion 622a is similar to the interface portion 440 described
above and thus defines a threaded surface 442. The threaded surface
442 is adapted to mate with the inner transition surface 142 of the
example fixed member 122 to detachably attach the example actuator
assembly 620 to the aerosol system 22 such that the outlet member
624 engages the valve assembly 50. The aerosol system 22 is
supported below the example actuator assembly 620 during normal
use. With the aerosol system so supported by the interface portion
622a, clockwise movement of the trigger member 630 results in
counterclockwise movement of the trigger link 632, which in turn
causes the outlet member 624 to move downward, place the valve
assembly 50 in its open configuration, and dispense contained
material through the outlet assembly 628.
[0078] While not explicitly shown in the interests of brevity and
clarity, the example actuator assembly 620 may be adapted to be
connected to the aerosol system 22 using the interface portions 450
or 460 and the example fixed members 222 and 322 described
above.
[0079] Turning now to FIGS. 19 and 20, depicted therein is an
example actuator assembly 650 that is adapted to be connected to
the aerosol system 22 using the example fixed member 122 described
above. The example actuator member 650 comprises a handle housing
652, an outlet member 654, a trigger assembly 656, and an outlet
assembly 658. Optionally, the outlet assembly 658 may define an
adjustable orifice. The example trigger assembly 656 comprises a
trigger member 660 and a trigger link 662. The trigger member 660
is supported for pivoting movement relative to the handle housing
662 about a first pivot axis 664. The trigger link 662 is supported
for pivoting movement relative to the handle housing 652 about a
second pivot axis 666. The trigger member 660 defines a first gear
portion 670 and the trigger link 662 defines a second gear portion
672, and the first and second gear portions 670 and 672 are
operatively connected such that clockwise rotation of the trigger
member 660 results in counterclockwise rotation of the trigger link
662. Accordingly, rotating the trigger member 660 in a clockwise
direction causes the trigger member 656 to rotate the trigger link
662 upwardly in a counterclockwise direction such that a trigger
projection 674 on the trigger link 662 displaces the outlet member
654 upward relative to the handle housing 652.
[0080] The example handle housing 652 defines an interface portion
652a configured to face above the handle housing 652 during normal
use of this example actuator assembly 650. The example interface
portion 652a is similar to the interface portion 440 described
above and thus defines a threaded surface 442. The threaded surface
442 is adapted to mate with the inner transition surface 142 of the
example fixed member 122 to detachably attach the example actuator
assembly 650 to the aerosol system 22 such that the outlet member
654 engages the valve assembly 50. The aerosol system 22 is
supported above the example actuator assembly 650 during normal
use. With the aerosol system so supported by the interface portion
652a, clockwise movement of the trigger member 660 results in
counterclockwise movement of the trigger link 662, which in turn
causes the outlet member 654 to move upward, place the valve
assembly 50 in its open configuration, and dispense contained
material through the outlet assembly 658.
[0081] While not explicitly shown in the interests of brevity and
clarity, the example actuator assembly 650 may be adapted to be
connected to the aerosol system 22 using the interface portions 450
or 460 and the example fixed members 222 and 322 described
above.
[0082] Turning now to FIGS. 21 and 22 of the drawing, depicted
therein is an example actuator assembly 720 that is adapted to be
connected to the aerosol system 22 using the first example fixed
member 122 described above. The example actuator assembly 720
comprises a handle housing 722, an outlet member 724, a trigger
member 726, and an outlet assembly 728. Optionally, the outlet
assembly 728 may define an adjustable orifice. The example trigger
member 726 comprises a finger portion 730 and a trigger projection
732. The trigger member 726 is rotatably connected to the handle
housing 722 at an axis 734. Displacing the finger portion 730 in a
first direction causes the trigger member 726 to rotate about the
axis 734 such that the trigger projection 732 displaces the outlet
member 724 downwardly relative to the handle housing 722. The
example actuator assembly 720 further comprises limit member 740 in
the form of a set screw, but the limit member 740 can take other
forms.
[0083] The example handle housing 722 defines an interface portion
722a comprising a threaded surface 442 that is similar to the
interface portion 440 described above. The example interface
portion 722a is below the handle housing 722 during normal use of
this example seventh example actuator assembly 720. The threaded
surface 442 is adapted to mate with the inner transition surface
142 of the example fixed member 122 to detachably attach the
example actuator assembly 720 to the aerosol system 22 such that
the outlet member 724 engages the valve assembly 50. The aerosol
system 22 is supported below the example actuator assembly during
normal use. So attached, downward movement of the trigger
projection 732 caused by displacement of the finger portion 730
causes the outlet member 724 to move downward, place the valve
assembly 50 in its open configuration, and dispense contained
material through the outlet assembly 728.
[0084] The limit member 740 is movably supported by the handle
housing 722 to limit movement of the trigger member 726. The limit
member 740 may thus be configured to limit operation of the trigger
member 726, which thereby limits an opening defined by the valve
assembly 50, which in turn limits the amount of material dispensed
when the trigger member 726 is displaced to open the valve assembly
50.
[0085] FIG. 23 depicts an example actuator assembly 820 that is
adapted to be connected to the aerosol system 22 using the example
fixed member 122 described above. The example actuator member 820
comprises a handle housing 822, an outlet member 824, a trigger
member 826, and an outlet assembly 828. Optionally, the outlet
assembly 828 may define an adjustable orifice. The example trigger
member 826 comprises a finger portion 830 and a trigger projection
832. The trigger member 826 is pivotably connected to the handle
housing 822 at a hinge point 834. Displacing the finger portion 830
in a first direction causes the trigger member 826 to pivot about
the hinge point such that the trigger projection 832 displaces the
outlet member 824 upwards relative to the handle housing 822.
[0086] The example handle housing 822 defines first and second
interface portions 840 and 842. In the example actuator member 820,
both the first and second interface portions 840 and 842 are
located above the handle housing 822 during normal use. However,
the first interface portion 840 may be located behind, below, or
within the handle housing 822. As will be described in detail
below, the second interface portion 842 supports material that is
fed by gravity into the handle housing 822, in which case the
second interface portion must be arranged above the handle housing
822. The position of the second interface portion 842 may be
changed, however, with other feed systems such as a Venturi feed
system or the like.
[0087] The first interface portion 840 is similar to the interface
portion 440 defined above and comprises a threaded surface 442. The
threaded surface 442 defined by the interface portion 840 is
adapted to mate with the inner transition surface 142 of the
example fixed member 122 to detachably attach the example actuator
assembly 820 to the aerosol system 22 such that the outlet member
424 engages the valve assembly 50.
[0088] The second interface portion 842 comprises a valve assembly
850 and a hopper structure 852 defining a bag interface portion
854. The hopper structure 852 is adapted to support a product bag
860 comprising a bag opening structure 862. The bag opening
structure 862 is received by the bag interface portion 854 to allow
fluid to flow out of the product bag 860 and to the valve assembly
850.
[0089] The valve housing defines a fluid flow path extending from a
feed chamber 870, through a feed channel 872, through a mixing
chamber portion 874, and an outlet channel 876. The outlet channel
876 is in fluid communication with the outlet assembly 828.
[0090] In use, the product bag 860 is supported by the hopper
structure 852 with the bag opening structure 862 engaged with the
bag interface portion 854 such that product within the product bag
860 may flow towards the valve assembly 850. When the valve
assembly 850 is opened, the product is allowed to flow into the
mixing chamber 874.
[0091] The aerosol system 22 is supported above the example
actuator assembly 820 during normal use. So attached, upward
movement of the trigger projection 832 caused by displacement of
the finger portion 830 causes the outlet member 824 to move upward,
place the valve assembly 50 in its open configuration, and dispense
contained material through the outlet assembly 828. In the example
actuator assembly 820, the contained aerosol material dispensed
from the aerosol system 22 is mixed with the product within the
mixing chamber. The aerosol material dispensed from the aerosol
system 22 is pressurized and entrains the product in the mixing
chamber 874 and carries the product out of the outlet assembly 828
in a spray.
[0092] While not explicitly shown in the interests of brevity and
clarity, the example actuator assembly 820 may be adapted to be
connected to the aerosol system 22 using the interface portions 450
or 460 and the example fixed members 222 and 322 described
above.
[0093] Turning now to FIGS. 24-26 of the drawing, depicted therein
is an example actuator assembly 1020 adapted to be connected to an
aerosol system 1022 to facilitate the dispensing of material from
the aerosol system 1022. The example actuator assembly 1020 and
aerosol system 1022 are of particular significance in the
dispensing of coatings such as texture material, and that
application of the invention will be described herein below.
[0094] The example aerosol system 1022 is or may be conventional
and will be described herein only to that extent necessary for a
complete understanding of the present invention. The example
aerosol system 1022 comprises a container 1024, a valve assembly
1026, and first and second crimp portions 1028a and 1028b. The
container 1024 defines a container axis A1.
[0095] The example actuator assembly 1020 comprises a handle
housing 1030, an outlet member 1032, a trigger member 1034, and an
outlet assembly 1036.
[0096] The handle housing 1030 comprises a support wall 1040 and a
handle wall 1042, and detent projections 1044 and 1046 are formed
in the support wall 1040. The support wall 1040 further extends
rearwardly from the handle wall 1042 such that, in use, the support
wall 1040 can rest on or otherwise engage the user's forearm when
the user's hand is gripping the handle wall 1042 and the trigger
member 1034 as will be described in further detail below. Further,
the support wall 1040 is configured to support the aerosol system
1022 as will be described in further detail below.
[0097] The outlet member 1032 comprises a connecting end 1050, a
distal end 1052, and an outlet ring 1054. The outlet member 1032 is
supported for sliding movement relative to the handle housing 1030
along an outlet axis A2.
[0098] The outlet assembly 1036 is secured to the distal end 1052
of the outlet member 1032. Optionally, the outlet assembly 1036 may
define an adjustable orifice to facilitate the dispensing of
texture material in different texture patterns.
[0099] The example trigger member 1034 comprises a finger portion
1060 and a trigger projection 1062. The trigger member 1034 is
rotatably connected to the handle housing 1030 about a trigger axis
A3. Further, the trigger projection 1062 on the trigger member 1034
engages outlet ring 1054 such that pivoting or circular movement of
the trigger projection 1062 causes linear movement of the outlet
member 1032 along the outlet axis A2.
[0100] In use, the container 1024 is arranged such that the
container axis A1 is aligned with the outlet axis A2 and displaced
along the outlet axis until the connecting end 1050 of the outlet
member 1032 engages the valve 1026. The housing support wall 1040
supports the container 1024 when the outlet member connecting end
1050 engages the valve 1026. Further, the detent projections 1044
and 1046 engage the first crimp portion 1028a to inhibit movement
of the container 1034 along the outlet axis A2 when the outlet
member connecting end 1050 engages the valve 1026.
[0101] At this point, the user grips the handle wall 1042 and
squeezes the finger portion 1060 of the trigger member 1034 towards
the handle wall 1042. Rotating movement of the finger portion 1060
causes similar rotating movement of the trigger projection 1062.
Movement of the trigger projection causes linear movement of the
outlet member 1032 towards the valve assembly 1026. The connecting
end 1050 of the outlet member 1032 places the valve assembly 1026
in its open configuration, allowing dispensed material to flow out
of the aerosol system 1022 through the outlet member 1032 and the
outlet assembly 1036.
[0102] FIG. 26 illustrates that the support wall 1040 extends along
a substantial portion, or at least half, of a length of the
container 1024 in a direction along the container axis A1. The
support wall 1040 thus provides support for the container 1024 of
the aerosol system 1022 when in use.
[0103] FIG. 27 illustrates an example actuator assembly 1120
adapted to be connected to aerosol systems 1122a and 1122b to
facilitate the dispensing of material from an aerosol system. The
example actuator assembly 1120 and aerosol system 1122a and 1122b
are of particular significance in the dispensing of coatings such
as texture material, and that application of the invention will be
described herein below.
[0104] The example aerosol systems 1122a and 1122b are or may be
conventional and will be described herein only to that extent
necessary for a complete understanding of the present invention.
The example aerosol systems 1122a and 1122b comprise containers
1124a and 1124b, valve assemblies 1126a and 1126b, and crimp
portions (not visible in FIG. 27), respectively. The containers
1124 define container axes A3 and A4, respectively.
[0105] The example actuator assembly 1120 comprises a handle
housing 1130, first and second outlet members (not visible), a
trigger member (not visible), and first and second outlet
assemblies 1136a and 1136b.
[0106] The handle housing 1130 comprises a support wall 1140 and a
handle wall (not visible), and detent projections 1144 and 1146 are
formed in the support wall 1140. The support wall 1140 further
extends rearwardly from the handle wall such that, in use, the
support wall 1140 can rest on or otherwise engage the user's
forearm when the user's hand is gripping the handle wall and the
trigger member. Further, the support wall 1140 is configured to
support the aerosol systems 1122a and 1122b as shown in FIG.
27.
[0107] Turning now to FIGS. 28 and 29 of the drawing, depicted
therein is an example actuator assembly 1220 adapted to be
connected to an aerosol system 1222 to facilitate the dispensing of
material from the aerosol system 1222. The example actuator
assembly 1220 and aerosol system 1222 are of particular
significance in the dispensing of coatings such as texture
material, and that application of the invention will be described
herein below.
[0108] The example aerosol system 1222 is or may be conventional
and will be described herein only to that extent necessary for a
complete understanding of the present invention. The example
aerosol system comprises a container 1224, a valve assembly 1226,
and crimp portions 1228a and 1228b. The container 1224 defines a
container axis A5.
[0109] The example actuator assembly 1220 comprises a handle
housing 1230, an outlet member 1232, a trigger member 1234, and an
outlet assembly 1236.
[0110] The handle housing 1230 comprises a support wall 1240 and a
handle wall 1242, and detent projections 1244 and 1246 are formed
in the support wall 1240.
[0111] The outlet member 1232 comprises a connecting end 1250 and a
distal end 1252. The connecting end 1250 is arranged at
substantially a right angle to the distal end 1252. The outlet
member 1232 is supported for sliding movement relative to the
handle housing 1230 along an outlet axis A6. The outlet axis A6 is
substantially vertical during normal use of the example actuator
assembly 1220.
[0112] The outlet assembly 1236 is secured to the distal end 1252
of the outlet member 1232. Optionally, the outlet assembly 1236 may
define an adjustable orifice to facilitate the dispensing of
texture material in different texture patterns.
[0113] The example trigger member 1234 comprises a finger portion
1260 and a trigger projection 1262. The trigger member 1234 is
rotatably connected to the handle housing 1230 about a trigger axis
A7. Further, the trigger projection 1262 on the trigger member 1234
engages outlet member 1232 such that pivoting or circular movement
of the trigger projection 1262 causes linear movement of the outlet
member 1232 along the outlet axis A6.
[0114] In use, the container 1224 is arranged such that the
container axis A5 is aligned with the outlet axis A6 and displaced
along the outlet axis A6 until the connecting end 1250 of the
outlet member 1232 engages the valve 1226. The housing support wall
1240 supports the container 1224 when the outlet member connecting
end 1250 engages the valve 1226. Further, the detent projections
1244 and 1246 engage the crimp portion 1228b to inhibit movement of
the container 1224 along the outlet axis A6 when the outlet member
connecting end 1250 engages the valve 1126.
[0115] At this point, the user grips the handle wall 1242 and
squeezes the finger portion 1260 of the trigger member 1234 towards
the handle wall 1242. Rotating movement of the finger portion 1260
causes similar rotating movement of the trigger projection 1262.
Movement of the trigger projection causes linear movement of the
outlet member 1232 towards the valve assembly 1226. The connecting
end 1250 of the outlet member places the valve assembly 1226 in its
open configuration, allowing dispensed material to flow out of the
aerosol system 1222 through the outlet member 1232 and the outlet
assembly 1236.
[0116] Turning now to FIGS. 30 and 31 of the drawing, depicted
therein is an example actuator assembly 1320 adapted to be
connected to an aerosol system 1322 to facilitate the dispensing of
material from the aerosol system 1322. The example actuator
assembly 1320 and aerosol system 1322 are of particular
significance in the dispensing of coatings such as texture
material, and that application of the invention will be described
herein below.
[0117] The example aerosol system 1322 is or may be conventional
and will be described herein only to that extent necessary for a
complete understanding of the present invention. The example
aerosol system comprises a container 1324, a valve assembly 1326,
and crimp portions 1328a and 1328b. The container 1324 defines a
container axis A8.
[0118] The example actuator assembly 1320 comprises a handle
housing 1330, an outlet member 1332, a trigger member 1334, and an
outlet assembly 1336.
[0119] The handle housing 1332 comprises a support wall 1340 and a
handle wall 1342, and detent projections 1344 and 1346 are formed
in the support wall 1340. The support wall 1340 is configured to
support the aerosol system 1322 as will be described in further
detail below.
[0120] The outlet member 1332 comprises a connecting end 1350 and a
distal end 1352. The connecting end 1350 is arranged at
substantially a right angle to the distal end 1352. The outlet
member 1332 is supported for rotating movement relative to the
handle housing 1330 along an outlet axis A9. The outlet axis A9 is
substantially vertical during normal use of the example actuator
assembly 1320.
[0121] The outlet assembly 1336 is secured to the distal end 1352
of the outlet member 1332. Optionally, the outlet assembly 1336 may
define an adjustable orifice to facilitate the dispensing of
texture material in different texture patterns.
[0122] The example trigger member 1334 comprises a finger portion
1360 and a trigger projection 1362. The trigger member 1334 is
rotatably connected to the handle housing 1330 about a trigger axis
A10.
[0123] In use, the container 1324 is arranged such that the
container axis A8 is aligned with the outlet axis A9 and displaced
along the outlet axis A9 until the connecting end 1350 of the
outlet member 1332 engages the valve 1326. The housing support wall
1340 supports the container 1324 when the outlet member connecting
end 1350 engages the valve 1326. Further, the detent projections
1344 and 1346 engage the crimp portion 1338a to inhibit movement of
the container 1324 along the outlet axis A9 when the outlet member
connecting end 1350 engages the valve 1326.
[0124] At this point, the user grips the handle wall 1342 and
squeezes the finger portion 1360 of the trigger member 1334 towards
the handle wall 1342. Movement of the trigger projection causes
linear movement of the outlet member 1332 towards the valve
assembly 1326. The connecting end 1350 of the outlet member 1326
places the valve assembly 1326 in its open configuration, allowing
dispensed material to flow out of the aerosol system through the
outlet member 1332 and the outlet assembly 1336.
[0125] Turning now to FIG. 32 of the drawing, depicted therein is
an example actuator assembly 1420 adapted to be connected to an
aerosol system 1422 to facilitate the dispensing of material from
the aerosol system 1422. The example actuator assembly 1420 and
aerosol system 1422 are of particular significance in the
dispensing of coatings such as texture material, and that
application of the invention will be described herein below.
[0126] The example aerosol assembly 1422 is or may be conventional
and will be described herein only to that extent necessary for a
complete understanding of the present invention. The example
aerosol assembly comprises a container 1424 and a valve assembly
1426.
[0127] The example actuator assembly 1420 comprises a handle
housing 1430, an outlet member (not visible), a trigger member
1434, and an outlet assembly 1436.
[0128] The actuator assembly 1420 further comprises a conduit 1440
adapted to be connected between the handle housing 1430 and the
valve assembly 1426.
[0129] With the conduit 1440 connected between the handle housing
and the valve assembly 1426, the user squeezes the trigger member
1434 in order to dispense the material contained with the aerosol
system 1422. Any of the mechanisms described herein for causing
linear movement of an outlet member based on rotating or pivoting
movement of the trigger member may be used in the example actuator
assembly 1420.
[0130] Referring initially to FIGS. 33 and 34 of the drawings,
depicted therein is an example of an aerosol protection system 2020
constructed in accordance with, and embodying, the principles of
the present invention. The example protection system 2020 is used
with an aerosol system 2022. The example aerosol system 2022 is or
may be conventional and will be explained herein only to that
extent necessary for a complete understanding of the present
invention.
[0131] The example aerosol system 2022 comprises an aerosol
container 2030 and a valve cup 2032. The valve cup 2032 is mounted
to the container 2030 at a rim structure 2040 formed by a container
crimped portion 2042 and a valve cup crimped portion 2044. The
example aerosol assembly 2022 further comprises a valve assembly
2050 and a dip tube 2052. The example valve assembly 2050 comprises
a valve housing 2060, a valve seat member 2062, a valve member
2064, and a valve spring 2066. The valve member 2064 defines a
valve member cavity 2070 and a valve member projection 2072 that
extends into the valve cavity 2070.
[0132] The example valve cup 2032 defines an exterior surface 2080
having a mouth portion 2082, a throat portion 2084, and an undercut
portion 2086. A diameter of the mouth portion 2082 is smaller than
a diameter of the throat portion 2084. The undercut portion 2086
extends between the mouth portion 2082 and the throat portion 2084
and has a vector component that is substantially perpendicular to
an axis A defined by the container 2030 when the valve cup 2032 is
joined to the aerosol container 2030 by the rim structure 2040. The
exterior surface 2080 of the valve cup 2032 further defines an
outermost rim portion 2090 and a rim end portion 2092. The
cross-sectional area (and thus diameter) of the outermost rim
portion 2090 is larger than that of the rim end portion 2092, so
the rim end portion 2092 also has a vector component that is also
substantially perpendicular to the container axis A when the valve
cup 2032 is joined to the aerosol container 2030.
[0133] The aerosol system 2022 thus defines certain components and
features that will be accommodated by the various examples of the
protection system 2020 of the present invention as described
herein. To the contrary, the example protection system 2020 of the
present invention facilitates the use of aerosol systems of many
sizes, shapes, and configurations. In that context, the example
aerosol system 2022 will not be described again in detail in
connection with other examples of the aerosol assembly protection
systems of the present invention.
[0134] FIGS. 33 and 34 further show that the example protection
system 2020 comprises an example adapter member 2120 having a rim
portion 2122, a perimeter portion 2124, and a center portion 2130.
As perhaps best shown in FIG. 34, the example center portion 2130
is defined by a score line 2132 and a score opening 2134. The
perimeter portion 2124 extends between the score line 2132 and/or
score opening 2134 defined by the center portion 2130 and the rim
portion 2122.
[0135] As shown in FIG. 33, the example score line 2132 is a
V-shaped depression or cavity extending from an outer surface 2140
of the adapter member 2120 towards, but not completely to, an inner
surface 2142 of the adapter member 2120. The example score opening
2134 is a rectangular hole extending completely through the adapter
member 2120 from the outer surface 2140 to the inner surface 2142.
The score opening 2134 allows a tool 2150 such as a screwdriver to
be inserted at least partly through the score opening 2134.
[0136] The example rim portion 2122 is sized and dimensioned to
form a snap fit with the rim structure 2040. In particular, the
inner surface 2142 of the adapter member 2120 defines an outermost
surface portion 2160 and a return surface portion 2162. A
cross-sectional area (and thus diameter) of the outermost surface
portion 2160 substantially matches a cross-sectional area (and thus
diameter) defined by the outermost rim portion 2090 of the rim
structure 2040, and a cross-sectional area (and thus diameter) of
the surface return portion 2162 is slightly smaller than the
cross-sectional areas of the outermost surface portion 2160 and the
outermost rim portion 2090 of the rim structure 2040.
[0137] To assemble the example adapter member 2120 onto the aerosol
system 2022, the adapter member 2120 is displaced until the return
surface portion 2162 engages the outermost rim portion 2090.
Further displacement of the example adapter member 2120 causes the
rim portion 2122 of the adapter member 2120 to deflect or deform
slightly to allow the return surface portion 2162 to pass beyond
the slightly larger outermost rim portion 2090 and into a connected
configuration as shown in FIGS. 33 and 36. In the connected
configuration, the outermost surface portion 2160 is in contact
with the outermost rim portion 2090, and the return surface portion
2162 is in contact with the rim end portion 2092. Because of the
relative size relationships of the return surface portion 2162 and
the rim portions 2090 and 2092, the return surface portion 2162
positively engages the rim structure 2040 to inhibit inadvertent
removal of the adapter member 2120 from the aerosol system
2022.
[0138] At this point, a protected chamber 2170 is formed between a
portion of the cup exterior surface 2080 and a portion of the inner
surface 2142 of the example adapter member 2120. FIG. 33 further
shows that the center portion 2130 may be sized and dimensioned
relative to the rim portion 2122 such that a portion of the inner
surface 2142 of the adapter member 2120 defined by the center
portion 2130 may be in contact with the cup exterior surface 2080
to inhibit entry of contaminants into the valve member cavity
2070.
[0139] As shown in FIGS. 34 and 35, the center portion 2130 of the
adapter member 2120 may be removed from the rim portion 2122 and
the perimeter portion 2124 by inserting the tool 2150 through the
score opening 2134 and into the protected chamber 2170 and pivoting
the tool 2150 such that the adapter member 2120 is broken into a
first piece 2180 and a second piece 2182. The first piece 2180
corresponds to the rim portion 2122 and intermediate portion 2124
and remains in place on the aerosol system 2022, and the second
piece 2182 is formed by the center portion 2130. The second portion
2182 may be discarded at this point.
[0140] With the second piece 2182 formed by the center portion 2130
removed from the first piece 2180 formed by the rim portion 2122
and intermediate portion 2124 as shown in FIG. 36, access to the
protected chamber 2170, and also to the valve member cavity 2070 is
allowed. In this case, an actuator member or actuator assembly such
as an example actuator assembly 2190 depicted in FIG. 36 may be
engaged with the valve assembly 2050 to allow material to be
dispensed from the aerosol system 2022.
[0141] FIG. 37 shows that the example protection system 2020 may be
formed by an example adapter member 2220 having a rim portion 2222,
a perimeter portion 2224, a plug portion, 2226, and a center
portion 2230. The example center portion 2230 is defined by a score
line 2232 and a score opening 2234. The perimeter portion 2224
extends between the score line 2232 and/or score opening 2234
defined by the center portion 2230 and the rim portion 2222.
[0142] The example score line 2232 is a V-shaped depression or
cavity extending from an outer surface 2240 of the adapter member
2220 towards, but not completely to, an inner surface 2242 of the
adapter member 2220. The example score opening 2234 is a
rectangular hole extending completely through the adapter member
2220 from the outer surface 2240 to the inner surface 2242. The
score opening 2234 allows a tool such as a screwdriver to be
inserted at least partly through the score opening 2234.
[0143] The example rim portion 2222 is sized and dimensioned to
form a snap fit with the rim structure 2040. The plug portion 2226
extends from the perimeter portion 2224 of the second example
adapter member 2220 towards the valve cup 2032 when the adapter
member 2220 is secured to the aerosol assembly as shown in FIG.
37.
[0144] In particular, an outer surface 2250 of the plug portion
2226 defines a proximal surface portion 2252, a distal surface
portion surface portion 2254, and a transition surface portion
2256. A cross-sectional area (and thus diameter) of the proximal
surface portion 2252 substantially matches a cross-sectional area
(and thus diameter) defined by the mouth portion 2082 of the valve
cup 2032, while a cross-sectional area (and thus diameter) of the
distal surface portion 2254 substantially matches a cross-sectional
area (and thus diameter) defined by the throat portion 2084 of the
valve cup 2032. Further, a cross-sectional area (and thus diameter)
of the proximal surface portion 2252 is slightly smaller than the
cross-sectional area of the distal surface portion 2254 and of the
throat portion 2084 of the valve cup 2032.
[0145] To assemble the example adapter member 2220 onto the aerosol
system 2022, the adapter member 2220 is displaced until the distal
surface portion 2254 of the plug portion 2226 engages the mouth
portion 2082 of the valve cup 2032. Further displacement of the
example adapter member 2220 causes the plug portion 2226 to deflect
or deform slightly to allow the distal surface portion 2254 to pass
beyond the slightly smaller mouth portion 2082 and into a connected
configuration as shown in FIG. 37. In the connected configuration,
the rim portion 2222 is in contact with the rim structure 2040, and
the distal surface portion 2254 is beyond the undercut portion 2086
such that the plug portion 2226 positively engages the valve cup
2032 to inhibit inadvertent removal of the adapter member 2220 from
the aerosol system 2022.
[0146] At this point, a protected chamber 2270 is formed between a
portion of the cup exterior surface 2080 and a portion of the inner
surface 2242 of the example adapter member 2220. FIG. 37 further
shows that the center portion 2230 may be sized and dimensioned
relative to the rim portion 2222 such that a portion of the inner
surface 2242 of the adapter member 2220 defined by the center
portion 2230 may be in contact with the cup exterior surface 2080
to inhibit entry of contaminants into the valve member cavity
2070.
[0147] The center portion 2230 of the adapter member 2220 may be
removed from the rim portion 2222 and the perimeter portion 2224 by
inserting a tool through the score opening 2234 and into the
protected chamber 2270 and pivoting the tool such that the adapter
member 2220 is broken into a first piece and a second piece. The
first piece corresponds to the rim portion 2222 and intermediate
portion 2224 and remains in place on the aerosol system 2022, and
the second piece is formed by the center portion 2230. The center
portion 2230 may be discarded at this point.
[0148] With the second portion 2230 removed, access to the
protected chamber 2270 and the valve member cavity 2070 is allowed.
In this case, an actuator member or actuator assembly may be
engaged with the valve assembly 2050 to allow material to be
dispensed from the aerosol system 2022.
[0149] FIG. 38 shows that the example protection system 2020 may be
formed by an example adapter member 2320 having a rim portion 2322,
a perimeter portion 2324, a plug portion, 2326, and a center
portion 2330. The example center portion 2330 is defined by a score
line 2332 and a score opening 2334. The perimeter portion 2324
extends between the score line 2332 and/or score opening 2334
defined by the center portion 2330 and the rim portion 2322.
[0150] The example score line 2332 is a V-shaped depression or
cavity extending from an outer surface 2340 of the adapter member
2320 towards, but not completely to, an inner surface 2342 of the
adapter member 2320. The example score opening 2334 is a
rectangular hole extending completely through the adapter member
2320 from the outer surface 2340 to the inner surface 2342. The
score opening 2334 allows a tool such as a screwdriver to be
inserted at least partly through the score opening 2334.
[0151] The plug portion 2326 extends from the perimeter portion
2324 of the example adapter member 2320 towards the valve cup 2032
when the adapter member 2320 is secured to the aerosol assembly as
shown in FIG. 38.
[0152] In particular, an outer surface 2350 of the plug portion
2326 defines a proximal surface portion 2352, a distal surface
portion 2354, and a transition surface portion 2356. A
cross-sectional area (and thus diameter) of the proximal surface
portion 2352 substantially matches a cross-sectional area (and thus
diameter) defined by the mouth portion 2082 of the valve cup 2032,
while a cross-sectional area (and thus diameter) of the distal
surface portion 2354 substantially matches a cross-sectional area
(and thus diameter) defined by the throat portion 2084 of the valve
cup 2032. Further, a cross-sectional area (and thus diameter) of
the proximal surface portion 2352 is slightly larger than the
cross-sectional area of the distal surface portion 2354 and of the
throat portion 2084 of the valve cup 2032.
[0153] In addition, the inner surface 2342 of the adapter member
2320 defines an outermost surface portion 2360 and a return surface
portion 2362. A cross-sectional area (and thus diameter) of the
outermost surface portion 2360 substantially matches a
cross-sectional area (and thus diameter) defined by the outermost
rim portion 2090 of the rim structure 2040, and a cross-sectional
area (and thus diameter) of the surface return portion 2362 is
slightly smaller than the cross-sectional areas of the outermost
surface portion 2360 and the outermost rim portion 2090 of the rim
structure 2040.
[0154] To assemble the example adapter member 2320 onto the aerosol
system 2022, the adapter member 2320 is displaced until the distal
surface portion 2354 of the plug portion 2326 engages the mouth
portion 2082 of the valve cup 2032 and the return surface portion
2362 engages the outermost rim portion 2090. The plug portion 2326
engages the valve cup 2032 in a manner similar to that of the plug
portion 2226 described above, and the rim portion 2322 engages the
rim structure 2040 in a manner similar to that of the rim portion
2122 described above.
[0155] At this point, a protected chamber 2370 is formed between a
portion of the cup exterior surface 2080 and a portion of the inner
surface 2342 of the example adapter member 2320. FIG. 38 further
shows that the center portion 2330 may be sized and dimensioned
relative to the rim portion 2322 such that a portion of the inner
surface 2342 of the adapter member 2320 defined by the center
portion 2330 may be in contact with the cup exterior surface 2080
to inhibit entry of contaminants into the valve member cavity
2070.
[0156] The center portion 2330 of the adapter member 2320 may be
removed from the rim portion 2322 and the perimeter portion 2324 by
inserting a tool through the score opening 2334 and into the
protected chamber 2370 and pivoting the tool such that the adapter
member 2320 is broken into a first piece and a second piece. The
first piece corresponds to the rim portion 2322 and intermediate
portion 2324 and remains in place on the aerosol system 2022, and
the second piece is formed by the center portion 2330. The center
portion 2330 may be discarded at this point.
[0157] With the center portion 2330 removed, access to the
protected chamber 2370 and the valve member cavity 2070 is allowed.
In this case, an actuator member or actuator assembly may be
engaged with the valve assembly 2050 to allow material to be
dispensed from the aerosol system 2022.
[0158] FIG. 39 shows that the example protection system 2020 may
also comprise an example adapter member 2420 having a rim portion
2422, a spacing portion 2424, and a center portion 2430. As perhaps
best shown in FIG. 39, the example center portion 2430 is defined
by a score line 2432 and a score opening 2434. The spacing portion
2424 extends between the score line 2432 and/or score opening 2434
defined by the center portion 2430 and the rim portion 2422.
[0159] As shown in FIG. 39, the example score line 2432 is a
V-shaped depression or cavity extending from an outer surface 2440
of the adapter member 2420 towards, but not completely to, an inner
surface 2442 of the adapter member 2420. The example score opening
2434 is a rectangular hole extending completely through the adapter
member 2420 from the outer surface 2440 to the inner surface 2442.
The score opening 2434 allows a tool such as a screwdriver to be
inserted at least partly through the score opening 2434.
[0160] The example rim portion 2422 is sized and dimensioned to
form a snap fit with the rim structure 2040 in the same basic
manner as the example rim portion 2122 described above. To assemble
the example adapter member 2420 onto the aerosol system 2022, the
adapter member 2420 is displaced until the rim portion 2122 forms a
snap fit with the rim structure 2040.
[0161] At this point, a protected chamber 2470 is formed between a
portion of the cup exterior surface 2080 and a portion of the inner
surface 2442 of the example adapter member 2420. However, the
example spacing portion 2424 takes the form of an elongate cylinder
extending from the rim portion 2422 to allow the use of a valve
assembly 2050 having a preassembled male actuator member 2472 as
shown in FIG. 39. FIG. 39 further shows that the spacing portion
2424 and the center portion 2430 may be sized and dimensioned to be
in contact with the actuator member 2472 to inhibit entry of
contaminants into the valve member cavity 2070.
[0162] As above, the center portion 2430 of the adapter member 2420
may be removed from the rim portion 2422 and the spacing portion
2424 by inserting a tool through the score opening 2434 and into
the protected chamber 2470 and pivoting the tool such that the
adapter member 2420 is broken into a first piece and a second
piece. The first piece corresponds to the rim portion 2422 and
intermediate portion 2424 and remains in place on the aerosol
system 2022, and the second piece is formed by the center portion
2430. The center portion 2430 may be discarded at this point.
[0163] With the center portion 2430 removed, access to the
protected chamber 2470, and also to the valve member cavity 2070 is
allowed. In this case, an actuator member or actuator assembly may
be engaged with the valve assembly 2050 to allow material to be
dispensed from the aerosol system 2022.
[0164] Turning now to FIG. 40 of the drawing, depicted therein is
an example adapter member 2520 that may be used to form the adapter
system 2020 of the present invention. The example adapter member
2520 is similar to the example adapter member 2320, except that an
internal threaded adapter surface 2522 is formed on a plug portion
2524 of the adapter member 2520. The adapter surface 2522 allows a
separate dispensing assembly to be securely attached in a
predetermined relationship relative to the valve assembly 2050 of
the aerosol system 2022.
[0165] FIG. 41 depicts an example adapter member 2620 that may be
used to form the adapter system 2020 of the present invention. The
example adapter member 2620 is also similar to the example adapter
member 2320, except that an externally threaded adapter surface
2622 is formed on a spacing portion 2624 of the adapter member
2620. The adapter surface 2622 allows a separate dispensing
assembly to be securely attached in a predetermined relationship
relative to the valve assembly 2050 of the aerosol system 2022.
[0166] FIG. 42 depicts an example adapter member 2720 that may be
used to form the adapter system 2020 of the present invention. The
example adapter member 2720 is also similar to the example adapter
member 2320, except that snap projections 2722 are formed on a
lower wall 2724 of a perimeter portion 2726 of the adapter member
2720. The snap projections 2722 engage recesses formed on a
separate dispensing assembly such that the separate dispensing
assembly may be secured in a predetermined relationship relative to
the valve assembly 2050 of the aerosol system 2022.
