FIELD OF THE INVENTION
[0002] The present invention relates to the field of chemical
applicators, and more particularly to applicators operating under
pressure conditions both ambient and pressurized, for the delivery
of plant nutrients and treatments which are commercially available
in a more concentrated form than is required at application as a
dilute form of the concentrate.
BACKGROUND OF THE INVENTION
[0003] In the botanical maintenance field, workers are called upon
to apply a wide variety of chemicals to flora throughout the course
of a busy work day. At the worse case, a worker needs to obtain a
concentrated supply of a needed chemical or nutrient, measure a
given amount of the concentrated nutrient into a container, add
makeup diluent, typically water, to a level necessary to make up
the final concentration, and then close and put away the
concentrated supply container.
[0004] In terms of time, the worker is required to take a
significant amount of time in pouring, measuring, or weighing the
concentrated chemical, and in retrieving, handling, and re-storing
the concentrated chemical containers. Further, the process is not
only wasteful in terms of time, but it is likely to be messy and
produce significant spillage over a period of time. Further, where
the concentrate is left at the "fill site", a number of further
problems arise. Any time that concentrate is left at the job site,
hose bib, or utility sink, the disadvantages multiply. Functionally
it means that the user must return to the site, and that if extra
time had not been taken spills contaminate the site. Secondly,
leaving chemical at an additional site can lead to liability if
third parties come into contact with either the containers or the
spills.
[0005] Spillage creates further negative impact from lost
concentrate, the waste associated with clean up from paper towels
disposed of and rags which become soiled more quickly, and most
importantly from the increased contact with the chemical or
nutrient in its concentrated form by the worker. Many of the
chemicals and nutrients are harmful to workers, especially in their
concentrated state. Spillage directly onto the skin of the worker
is a particularly dangerous problem, with the degree of danger
dependent upon the type and concentration of the chemical in
question. Carriage is also a problem. Where a worker has one or two
containers of concentrated chemical or nutrient which comprises the
main ones of the materials to be used throughout the day, having to
separately handle the concentrated material containers in addition
to the main applicators, requires additional worker attention, time
and trouble. Taking up the attention of the worker when his or her
attention should be directed elsewhere enhances the danger
potential, especially around plants where a worker could be injured
upon impact by the plant.
[0006] What is needed is a system which frees the worker from
having to worry about handling and spillage, especially with regard
to the concentrated chemicals and nutrients which are used most
often. The needed system should include ease of dispensing and
re-stocking of the concentrated chemicals to eliminate worker
handling and the associated negative impact of spillage. The end
result of the needed system is reduced time for measuring, mixing
and diluting, and increased worker safety, as well as to promote
ease of usage so as to remove the barrier for people to feed their
plants regularly. The needed system should also increase the time
and ease of mixing and where possible prevent inadvertent spillage
of concentrated chemicals and nutrients.
SUMMARY OF THE INVENTION
[0007] The system of the present invention includes the provision
of a support of accommodation space on a gravity feed watering
device or on a pressurized applicator to both provide storage for
concentrated chemical containers, and metered measurement while
eliminating waste, make up time and minimizing contact between
workers and the chemicals or nutrients in their concentrated state,
and to encourage and facilitate the regular feeding of plants, by
reducing the trouble and bother associated with feeding plants to
increase the regularity with which plants are fed and watered. The
aforementioned mechanisms hold true for both commercial workers and
home plant enthusiasts, especially hobby growers. Further, the
invention makes it less dangerous to bring concentrated material
into sensitive areas such as hotel lobbies and restaurants, common
atrium areas and similar surroundings where minimum exposure is
desired. In terms of commercial workers, the invention should
reduce the liability while workers are on the job site by keeping
chemicals from children and by reducing or eliminating what would
be a further mixing station for the concentrated chemicals.
[0008] In normal usage, concentrated chemical or nutrient
containers are stored in a position near the periphery of the
entrance of the device, typically a watering device or applicator.
From an initial empty state, displacement dispensers atop the
concentrated chemical or nutrient containers applicators are
activated to meter a pre-determined amount or multiples of such
amount of concentrated chemical or nutrient into an opening of the
device. Typically water is then added under flowing pressure into
the opening to cause the metered chemical or nutrient to become
mixed upon the rapid gravity introduction of the water or other
mixture forming liquid.
[0009] Structure may be provided to prevent further concentrated
chemical or nutrient from being dispensed and may include structure
on the general device which blocks metering of the concentrated
chemical or nutrient, or blocking members may be placed directly on
the concentrated chemical or nutrient containers, or upon structure
connected with the main applicator housing which supports the
concentrated chemical or nutrient containers. In the alternative, a
raised concentrate reservoir may be combined with a catch bib to
insure that all chemical is either dispensed directly into the
reservoir or collected in the bib for drainage into the main
reservoir.
[0010] The manner of integration of the concentrated chemical or
nutrient containers into the main applicator can be controlled in
accord with shape to achieve important objectives. These objectives
may include permitting or encouraging the use of generally
compatible chemicals by integrating the container sizes to fit
within a provided space. Chemicals which should never be used
together can be placed in containers which will not physically fit
within the support space, for example.
[0011] Container support and holding spaces may be configured to
secure shapes and designs which are in existence or which may be in
existence. In some cases, the size of the accommodated containers
may be 7.5 inches, 8.5 inches, to 10.5 inches tall. The
accommodated containers may be round or cylindrical or triangular
or curved edge rectangular. The typical major width dimension may
be 3.5 inches, 4 inches 4.5 inches or 5.0 inches. A typical minor
width dimension may be 1.5 inches, 2.0 inches to 2.5 inches. The
volume of the liquid containers may be from eight ounces to sixteen
ounces to almost 40 ounces.
[0012] It is also contemplated that the applicator devices have
support spaces which may specifically match with a concentrated
chemical or nutrient container and in which the overall capacity of
the applicator structure matches with the volume of concentrated
chemical or nutrient metering capability of the concentrated
chemical or nutrient containers. This opens further the ability to
match concentrate containers with applicators. In some cases the
accommodation space can be maximized to, in essence, provide an
applicator with expanded concentrate containers. This in turn can
enhance the use of applicators which are built around a single or
even two or three concentrate containers.
[0013] In one stylish embodiment, the nutrient supply container is
situated largely within an integrally formed interfitting space
formed in a one piece embodiment of a gravity type applicator. A
nutrient container is fitted with a spout which extends into a slot
formed in the interfitting space, with the clearance such that the
spout is controlled laterally and vertically. While in the oval
shaped slot, the pump can be operated, but the spout is not free to
be turned or moved within the slot other than in an up-and-down
pumping action direction. Where the spout is fitted with an "eagle
beak" shaped spout, and where the pump is not spring urged to an
upper position, the spout can occupy a downward position after
dispensing nutrient and prevent any accidental actuation from an
inadvertent downward motion. The nutrient container is mounted
slightly higher than the bottom of the bottom of the gravity type
applicator to facilitate hand insertion underneath the nutrient
container to facilitate removal of the nutrient container. The
elimination of specialized structures mounted atop the reservoir
opening makes a cleaner appearance, but at the expense of lowering
the effective maximum fill level of the reservoir.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0055] The description and operation of the invention will be best
initiated with reference to FIG. 1 which illustrates a top view of
a gravity type applicator 11. The gravity type applicator 11 has a
housing 13 having a central opening 15, shown larger than it might
normally be provided for emphasis, to show common access by a first
container 17 within a first container accommodation space 19. Other
structure may be provided for stabilizing the first container 17
within its container accommodation space 19, however where the
first container 17 is largely surrounded and supported, further
structure is likely not necessary. First container 17 is typically
filled with a plant nutrient or chemical and may include a
pesticide, herbicide, nitrogen food or any concentrated chemical,
typically in the liquid state. Container 17 has, from an upper
perspective looking downward, a trapezoidal shape, or somewhat
truncated triangular shape, and includes a pump applicator assembly
21 with a spout extension 23 which preferably extends over central
opening 15 to allow for ease and secure gravitational deposition of
dispensed liquids from container 17 and into a main reservoir of
the gravity type applicator 11 and in which mixing may occur. An
optional "c" shaped locking clip 24 may be provided to lock the
spout extension 23 in an up position, to prevent further dispensing
of the concentrate, and such clip 24 may be attached loosely to the
pump applicator assembly 21. The central opening 15 can be smaller
so long as the extension 23 can gravitationally extend over it
enough to reliably deposit a desired amount of concentrated
material.
[0056] Further, it is preferable that the pump applicator assembly
21 have a known or pre-determined metering capability, typically in
terms of ab even number of full stroke vertical pump shaft
displacements to enable accurate metering of the nutrient or other
chemical through the central opening 13. This arrangement enables
the user to take the guess work out of measurements and to reduce
the reservoir replenishment steps to two, namely operating the pump
applicator assembly 21 followed by the introduction of solvent,
carrier or other effluent, typically water, into the reservoir
connected to the central opening 15.
[0057] Note that the first container accommodation space 19
registers the orientation of the first container 17 and insures
that the first container 17 must be inserted in a way in which the
pump applicator assembly 21 must be closest to the central opening
15. Despite this physical ordering, the spout extension 23 still
needs to be directed over the central opening 15. If the spout
extension 23 is ordered with respect to the first container 17,
either directly as by an upwardly extending boss which permits the
spout extension 23 to be depressed only when the spout extension 23
is over the central opening; or by registration from the first
container 17, through the pump applicator assembly 21 and thence to
the spout extension 23, it can be seen that a mechanical scheme can
be employed to prevent the pump operation when the spout extension
23 is in a position other than directly over the central opening
15. Such a scheme can further help to prevent spillage and also
prevent unwanted or inadvertent actuation of the pump mechanisms.
In other words, during times when liquid from the first container
17 is not being metered into the central opening 15, the turning of
the spout extension 23 can provide a lockout mechanism.
[0058] Also seen is a second container 25 within a second container
accommodation space 27. The shape of both the second container 25
and the a second container accommodation space 27 are both round or
cylindrical which is likely not to afford registration through the
second container accommodation space 27 and second container 25.
However, registration may be made through a structure extending
from the applicator 11 housing 13, which is not seen in FIG. 1 for
clarity of illustration.
[0059] Other structures seen in FIG. 1 include a flow tube 31 and
an angle brace 33 between flow tube 31 and the main housing 13. At
the end of the flow tube 31, a strainer or flow dispenser 35 is
pivotally mounted adjacent an open end 37 to enable flow dispersion
and also to limit the flow to a convenient rate. Pivotal attachment
enables the flow dispenser 35 to be selectively utilized and
possibly interchanged with other flow dispersers 35 having greater
and lesser aperture areas. The top view of FIG. 1 omits any handle
structure over the top of the applicator 11 so that the structures
can be shown with greater clarity.
[0060] Referring to FIG. 2, a side view of applicator 11
illustrates an integral handle 41 which extends from a rear side 43
of the gravity type applicator 11, upward and over the central
opening 15 and toward a portion of the top of the gravity type
applicator 11 near a front side 45. From the view seen in FIG. 2,
the view of first container 17 is most prominently seen. The first
container accommodation space 19 is shown as an opening and pocket
which allows the first container to take up or displace space
within the reservoir 49 which may include a water level 51. The
degree to which the first container accommodation space 19
"invades" the reservoir 49 area will depend upon the size and
configuration of reservoir 49 needed and the ability of one or more
of the first and second containers 17 and 25 to either invade the
space of the reservoir 49 or to become extended outboard of the
applicator 11.
[0061] Also seen in FIG. 2 is a pocket area 53 for insertion of an
information placard which may include information on one or more of
the concentrated chemicals or nutrients within first and second
containers 17 and 25, or relating to the use of gravity type
applicator 11 in its expected mode of use. The physical structure
of the pocket area 53 may include an attachable pocket onto a flat
surface or a depressed surface within which a label may be
attached.
[0062] FIG. 2 also illustrates the action of the flow dispenser 35
and its pivoting connection 55 onto the flow tube 31. As can be
seen, the flow dispenser 35 can be pivoted out of the way into a
storage position or into place over the open end 37. The user
controls the position of the flow dispenser 35 at will and the use
of flow dispenser 35, especially depending upon which types of
plant application is to be had such as a bulk application at the
base or a sprinkling application at top.
[0063] Referring to FIG. 3, a closeup view taken along line 3 of
FIG. 2 illustrates further details and including further details of
operation. Flow dispenser 35, seen from side view, may have a catch
57 and a pair of spaced apart centering lugs 59 which may engage
the inside edges of the flow tube 31. Referring to FIG. 4, a view
taken along line 4-4 of FIG. 3 illustrates a view looking onto the
flow dispenser 35 when it is in closed position. As can be seen,
the flow dispenser 35 has an array of apertures 59 to admit and
disperse liquid from the flow tube 31. Also seen are a pair of
holder structures 61 which are used to engaged the catch 57 when
the flow dispenser 35 is desired to be fixed in an out-of-the-way
upper position.
[0064] Referring to FIG. 5, a top view of a pressurizable
applicator 101 typically includes a relatively thick, pressurizable
body with a central opening 103 which may be threaded for
facilitating attachment with a pump unit (not shown). A curved
opening 105 may include an upper rail 107 for supporting several
individual concentrated chemical or nutrient containers, such as a
first concentrate container 111 or a second concentrate container
113. Each of the first and second concentrate containers 111 and
113 includes a pump assembly 115 having a spout extension 117. The
ends of the spout extensions extend over the opening 103 to enable
concentrate from the containers 111 and 113 to be dispensed
directly into the opening 103 which leads to the reservoir 119. The
upper portion of the pressurizable applicator 101 may have a drain
off collar 121 and spout 123 to assist in transfer of any dilute
solution which must be removed at the time of cleaning of the
pressurizable applicator 101.
[0065] Pressurizable applicator 101 is preferably fitted with a
hose 125 which is typically in constant communication with the
reservoir into which the opening 103 leads. In many pressurized
sprayers, the entire reservoir is pressurized while flow control is
effected with a wand mounted at the end of a hose, and the
pressurizable applicator 101 is shown in this type of
configuration. A pressure release valve 127 for venting pressure to
enable the pumping unit (not shown) to be removed from the
pressurizable applicator 101 without having to expel the liquid
from the reservoir 119.
[0066] Referring to FIG. 6, a top view of an integrated
pressurizable applicator 151 typically includes a relatively thick,
pressurizable body with a central opening 153 leading to a
reservoir 155. The central opening 153 may be threaded for
facilitating attachment with a pump unit (not shown). A curved area
157 identifies a liquid concentrate reservoir general area which is
built into the body of the integrated pressurizable applicator 151.
A blocking rail 161 is placed to cooperate with a pump assembly 163
having a pump depression handle 165 and extended spout 167 having a
tip end 169 positioned over the reservoir 155. When in an upward
position, as when the pump depression handle 165 is unactuated and
in the upper position, the extended spout 167 is above the level of
the blocking rail 161. As such, if the extended spout 167, which
typically can turn 360.degree. as in most pump assemblies including
163 is directed to any position other than a position where the tip
end 169 is over the reservoir 155 or a drain off collar 171 seen
adjacent the spout 173, the pump assembly 163 cannot be actuated.
Also seen is a short link chain 177 connected to the blocking rail
161 and also connected to a funnel 179. Where the area 157 as an
area for holding concentrate is integrated with the applicator 151,
a funnel 179 will help reduce spillage. Also seen are structures
previously seen in FIG. 5, including a hose 125 and release valve
127.
[0067] Referring to FIG. 7, a side view of the integrated
pressurizable applicator 151 is shown with a pumping unit 181
having a prominent handle 183. Typically the handle 183 can be
locked with respect to the pumping unit 181 to permit the handle
183 to be utilized to carry the whole integrated pressurizable
applicator unit 151. It is also seen more clearly that the blocking
rail 161 is an extension of the drain off collar 171.
[0068] The area seen as curved area 157 in FIG. 6 is in fact an
internally segregated reservoir area 157 now seen I FIG. 7. The
dashed barrier line 185 shows the boundary of the internal
concentrate reservoir generally represented by the area 157.
Barrier 185 provides a physical segregation between an internal
segregated area for holding concentrated chemicals or nutrients
which are fed through an opening over which the pump assembly 163
is secured. The shape of the actual area of the concentrate holding
volume will depend upon the shape and needs for the internal
pressurizable reservoir 155. As can be seen in FIG. 7, where the
extended spout 167 is swung to the right and over the blocking rail
161 that it cannot be depressed. The funnel 179 is mounted in a
manner that it will not be lost and in a position where it can be
brought over to an opening which is underneath the pump assembly
163, once the pump assembly 163 is removed to expose the opening
into the area 157 occupied by the concentrate reservoir. Also shown
is a pocket area 191 for placing instructions or labels onto the
applicator 151. It is understood that the blocking rail 161 could
be provided from the pump assembly 163 so long as the cap portion
of pump assembly 163 is registerable with respect to the
orientation of the central opening 153.
[0069] Referring to FIG. 8, a perspective view of an integrated
pressurizable applicator 201 is shown as having an integral
reservoir 203 mounted high upon what would otherwise be a
continuation of a shoulder 205 of the integrated pressurizable
applicator 201. The high mounting of the integral reservoir 203
enables a gravity safety system in lieu of the pump lockout
mechanism seen in FIG. 7. Rather than disable the operation of a
pump unit 211, a contoured gravity bib 213 is seen immediately
surrounding a cap 215. Regardless of the position of a spout 217,
any concentrate will flow into a reservoir 219. When the spout 217
is positioned directly over the reservoir 219, the concentrate
drops directly into the reservoir 219. When the spout 217 is
positioned elsewhere, any concentrate will flow onto the contoured
gravity bib 213 and then into the reservoir 219. Upon reaching the
filling with solute step, solute can be caused to run along the
contoured gravity bib 213 in order to wash it off, but with any
excess concentrate going directly into the reservoir 219.
[0070] As before, a hose 125 is seen, and also seen are threads 221
at the opening 223 which is again shown with a drain off collar
225. Further, the degree of integration of the integral reservoir
203 to the applicator 201 main body 227 will depend upon both
convenience and need. In the alternative, the contoured gravity bib
213 and drain off collar 225 could be made as a removable unit for
attachment about a neck 229 of applicator 201 where it is desired
to have a quick change complete applicator set.
[0071] Referring to FIG. 10, a left rear perspective view of a
second embodiment of a gravity type applicator 301 includes an
integral concentrate container 303. The integral concentrate
container 303 has a more gentle curve on the outside surface seen
in FIG. 10, and a curved rear and bottom sides which fit into an
accommodation space, not completely shown in FIG. 10 because it is
occupied by the interfitting integral concentrate container
303.
[0072] One aspect of the invention is the ability to provide a wide
variety of integral concentrate containers 303 of different colors
especially where any sort of applicator in this application is
utilized. This will enable personnel, especially un-skilled worker
personnel, to more easily keep up with the proper ones of the
integral concentrate containers 303 to be used. The integral
concentrate containers 303 may preferably be made of clear or light
dispersive plastic which transmits enough light to show the liquid
level inside. A tag may be used, especially which attaches onto a
neck of integral concentrate container 303 which shows specific
information including concentration, warnings, or special
instructions, including instructions on dispensing the
concentrate.
[0073] Most of the extent of the gravity type applicator 301, with
the exception of the integral concentrate container 303 forms a
reservoir for being filled with plant nutrient solution typically
predominantly including water. The gravity type applicator 301 is
predominantly hollow having a large top opening 305 leading into an
upper reservoir portion 307 which sits above an expanded base
reservoir portion 309. The expanded base reservoir portion 309
provides a wider and longer base which stabilizes the gravity type
applicator 301 to reduce the chances of spilling even when the
gravity type applicator 301 is inadvertently bumped or struck from
a position near an upper portion of its structure. A stepped
dividing zone 311 between the upper reservoir portion 307 and an
expanded base reservoir portion 309 is a slanted shelf which
extends from the front to the back of the gravity type applicator
301. The shelf nature of the dividing zone 311 becomes a more
steeply defined transition at the mid extent of the applicator 301.
At the rear extent, the dividing zone 311 forms its most horizontal
shelf extent and meets a heel portion 313 near the junction of an
arched handle 315. This area provides a hand hold to facilitate
plant feeding while the gravity type applicator 301 is raised over
the user's head, the user typically grasping the rear heel portion
313 with the user's hand with the user's fingers placed aside
either side of the arched handle 315 at the stepped dividing zone
311.
[0074] The base reservoir portion 309 curves gently upward toward
the front of the gravity type applicator 301 to provide some
forward loading when the applicator 301 is tilted forward. This
feature is combined with the arched handle 315 which extends from
the heel portion 313, across the top of the large top opening 305
and forward to the forward most end of the unified dividing zone
311 which forms the base of a spout portion 317. The area
immediately below the forward end of the arched handle 315 is an
upwardly tilted portion of the expanded base reservoir portion 309
underneath the more flattened upwardly disposed forward portion of
the dividing zone 311. This has the effect of extending the
expanded base reservoir portion 309 forward to both shift the
center of gravity forward upon tilting, and also to move the bulk
of the liquid away from the large opening 305 when the applicator
301 is tilted. This enables the user to worry less about spilling,
even when the applicator 301 is nearly full and tilted
significantly.
[0075] The spout portion 317 extends to an expansion fitting 319
and then to a cylindrical portion 323 which may support optional
engagement with a sprinkle screen assembly 325. The sprinkle screen
assembly 325 includes a cylindrical body portion 327 which supports
a pair of oppositely oriented hinge fittings 329, typically as a
pair of oppositely disposed apertures. A pair of oppositely
directed hinge projections 331 are integral with a sprinkle cover
333 which presents an outwardly curved multi aperture member. This
enables the sprinkle cover 333 to be folded back into "butterfly
style" held-open position where a user wants the sprinkle function
disabled, and out of the way of a more open flow.
[0076] The arched handle 315 may preferably be hollow both to
provide additional storage capacity especially at the rear of the
applicator 301, but also at the front of the applicator 301
adjacent the dividing zone 311. The front of the applicator 301
adjacent the dividing zone 311 also serves as a source of
displacement air so that as the applicator 301 is righted, all of
the balancing air need not come from back as being pulled through
the sprinkle cover 333.
[0077] Adjacent the large top opening 305 a vertical feature is
seen as a spout guide 339. This structure is attached, preferably
permanently, about a position adjacent and around a rim 341 of the
large top opening 305. It may be riveted with rivets 343 either to
the material of the applicator 301, or back onto its own material
where provided to hook around the rim 341.
[0078] The spout guide shown is designed to allow material to run
out a bottom 345 of a ramp not completely seen in FIG. 10 and over
a face 347 of a fitting 349 through which extends the rivet
343.
[0079] On either side of the ramp, and again the full extent of the
ramp is not seen in FIG. 10, are a pair of tall vertical
projections 351 and 353 which lie to either side of and displaced
slightly from a manual pump 355 having a spout 357. A portion of
spout 357 is obscured behind the projection 351. The manual pump
355 is threadably attached to the top of the integral concentrate
container 303.
[0080] When the integral concentrate container 303 is placed in its
accommodation space (to be more fully shown later), the spout 357
is simultaneously fitted into a position between the pair of
projections 351 and 353 as the integral concentrate container 303
is being fitted into place.
[0081] Once in place, the position of both the integral concentrate
container 303 and the projections 351 and 353 are such that the
manual pump 355 spout 357 is not free to turn either way. The
manual pump 355 may be actuated upwardly and downwardly by having
the user press onto the top of the manual pump 355 in a deliberate
manner. However, the manual pump 355 and spout 357 are protected
from any generalized downward striking motion by the protection
afforded by the projections 351 and 353.
[0082] Where the manual pump 355 and spout 357 structures are
upwardly spring loaded, they will return to their upper position as
is seen in FIG. 10. Where no spring loading is present, the manual
pump 355 and spout 357 may be left in a downward position (not
shown in FIG. 10) to provide even more protection against downward
actuation. However, since most pump assemblies available
commercially are spring loaded to assume an upward, ready-to-pump
orientation, the projections 351 and 353 will be of especial value
in providing coverage against inadvertent actuation when the manual
pump 355 and spout 357 are in the upward position.
[0083] Further, the projections 351 and 353 provide a "locked in"
guide which keeps the spout 357 in line and directly toward the
large top opening 305.
[0084] Reasonably non-destructive removal of the spout 357 from
between the projections 351 and 353 can effectively be accomplished
by removal of the integral concentrate container 303 from the
applicator 301. Conversely, and as can be seen in FIG. 10, the
integral concentrate container can be loaded in a different
orientation with the spout 357 not between the projections 351 and
353 so that reasonable care to load the integral concentrate
container 303 into the applicator 301 should be exercised. The
flared entrance to the space between the projections 351 and 353
facilitates the guiding of the spout 357 upon loading of the
integral concentrate container 303 into the applicator 301.
[0085] In terms of metering, the use of a guarded system provided
by the projections 351 and 353 prevents unintended actuation while
also facilitating the use of manual pumps 355 with different
metering capability. For a given neck size or metering plunger
area, metering limits are typically set by limiting the vertical
height over which manual pump 355 can travel. A small metered flow
would be accomplished by providing a manual pump 355 which might
have only a quarter inch stroke from the top of its travel path to
the bottom. In this case it would reside only in the lower area
between the projections 351 and 353. Since the projections 351 and
353 have a flared opening, it is not necessary for a high clearance
of the spout 357 over the projections 351 and 353. Manual pumps
similar to manual pumps 355 of any operating height may be utilized
in conjunction with the projections 351 and 353.
[0086] Also seen is a base collar 359 of the manual pump 355 which
further illustrates the advantages of the two projections 351 and
353 as a system which provides significant clearance for a wide
variety of fittings or base collars 359 of a manual pump 355.
Further, in terms of a stabilizing force, note that arched handle
315 is not only attached adjacent two dividing zones 311, but also
by attachment arm 361 at the more forward end of the applicator 301
and by attachment arm 363 at the more rearward end of the
applicator 301. Both the attachment arms 361 and 363 attach the
arched handle 315 to the upper sides of the upper reservoir portion
307. Preferably, but not required, is the presence and hollow
nature of the arched handle 315 and its communication with the
upper reservoir portion 307 as well as the expanded base reservoir
portion 309 at its two points of attachment adjacent the dividing
zone 311. This enables the arched handle 315 to hold additional
water on a level with water in the higher of the upper reservoir
portion 307 and expanded base reservoir portion 309 when the
applicator 301 is tilted. In essence, expanded water holding
capability combines with stability. In addition, displacement air
can also readily flow through the arched handle 315 especially from
its connection with the upper reservoir portion 307.
[0087] Referring to FIG. 11, a perspective view of the other side
of the applicator 301 illustrates a better view of the face 347 of
the spout guide 339. Now, above the bottom 345, a curved ramp 371
can be seen. The geometry seen in FIG. 11, combined with that of
FIG. 10 helps to complete an understanding of the flow of
concentrate after it leaves the end of the spout 357. The
concentrate drops onto the ramp 371 to flow over the face 347, and
through the large top opening 305 into the upper reservoir portion
307. The general configuration of the fitting 349 illustrates a
construction that is self contained, and prevents any dispensed
concentrate from entering any space between the fitting 349 and an
upper surface 373 of the upper reservoir portion 307. Further, the
ramp 371 will be continually washed with fresh amounts of
concentrate, of any type, and should generally operate to keep
itself clean. Clearing water can also be introduced down the ramp
371 on each subsequent filling of the applicator 303 to keep it
clean.
[0088] Notice also that gross volume measurement level marks are
present, including a volume mark 375 to indicate a two gallon level
and a volume mark 377 to indicate a one gallon level. Further
volume marks can be supplied both on the upper reservoir portion
307 and farther down on the expanded base reservoir portion 309
where necessary. However, given the precision metering ability of
the manual pump 355 and the more precise level measurement of
concentrate from the concentrate container 303, the user will be
able to control the concentrations accurately without having
smaller denomination measurements on the applicator 303
housing.
[0089] Referring to FIG. 12, an expanded view of the integral
concentrate container 303 being removed from the gravity type
applicator 301 illustrates further details thereof. The integral
concentrate container 303 is seen as having a front face 381
separate from the outer surface of the upper reservoir portion 307.
An upper surface 383 reveals that the integral concentrate
container 303 has a "D" shaped cross section which includes a
curved surface 385 which extends in a continuous curve from a left
to rear to right side smoothly.
[0090] This curved rear portion of its cross sectional shape allows
the integral concentrate container 303 to fit into a compartment
391 which includes a floor surface 393, a curved transition surface
395 and leading to a generally vertical, curved rear surface 397.
At the top of the compartment 391 a portion 399 of the upper
surface 373 comes forward in a thin "U" shape to engage a mating
surface located just below the base collar 359.
[0091] A series of relationships can be used to keep the integral
concentrate container 303 securely carried within the compartment
391. These can include for example making floor surface 393
slightly lower than an edge 401, or adjusting the portion 399 so
that it works in conjunction with the floor surface 393 to "trap"
the container 303, such as by being able to be deflected
upwardly.
[0092] Another mechanism is also shown in FIG. 12. A member 405 is
seen on the integral concentrate container 303 which may be either
a projection or a depression. Member 405 is positioned to
complementarily contact a member 407 on the inside of the generally
vertical, curved rear surface 397. Member 407 is the other of a
projection or depression and enables a hold in fit with the member
405. The fit relationship can be snap, interference, latch, spring
powered and the like or have a further relationship.
[0093] Also seen is the extension of the curved edge 401 along an
extent adjacent both the floor 393 and upward along both sides
adjacent to the generally vertical, curved rear surface 397. The
curvature of the edge can be severe or gentle to facilitate
handling by increasing or decreasing the ease with which the human
hand can grasp the integral concentrate container 303. The "D"
shaped curved surface 385 has a tighter radius of curvature at its
rearmost extent to facilitate the rapid, easy loading of the
integral concentrate container 303 into the compartment 391. The
integral concentrate container 303 can be, depending upon the
details of orientation, loaded by angling the bottom in first or by
first positioning the base collar 359 with respect to the portion
399 followed by pushing the bottom of the integral concentrate
container 303 into place. In some configurations integral
concentrate container 303 may be loaded in with a vertical
orientation. Removal of the integral concentrate container 303 can
be accomplished by grasping and pulling outwardly on the base
collar 359.
[0094] Front face 381 of the integral concentrate container 303 is
shown as being marked with volumetric indicator marks 411. Near the
bottom of the integral concentrate container 303, the front face
381 has an outward curvature 413 followed by a downward curvature
415 leading to a forwardly displaced vertical portion 417. However,
the integral concentrate container 303 need not have the exact
shape details seen in FIG. 12. Integral concentrate container 303
can also have manual assists for instances where it needs to be
changed more quickly or more often.
[0095] Referring to FIG. 13, a side view of the integral
concentrate container 303 is seen, without the manual pump 355 and
with the base collar 359 removed to expose an upper neck 421 having
a simple thread 423.
[0096] Referring to FIG. 14, a top view of the integral concentrate
container 303 again shows the upper neck 421 as having an opening
425. The curved surface 385 is shown as having about 180.degree. of
curvature having an even radius about the upper neck 421. The
180.degree. of curvature levels into a flat portion 427 and a flat
portion 429 identifiably seen for the first time in FIG. 14.
[0097] Referring to FIG. 15, a further embodiment of a pressurized
applicator is seen as integrated pressurizable applicator 501.
Applicator 501 has a body 503 having an integral internal reservoir
(not shown in FIG. 15) and a concentrate container system 505 which
includes a concentrate container 507, neck unit 509 and a pump unit
511 of which can be seen a collar 513, pump head 515 and spout
517.
[0098] Above the collar 513 and also mounted above the body 503 is
a potentially removable drainage basin 521. Drainage basin 521 can
be seen to act to prevent any downward motion on the pump head 515
by virtue of interference of the spout 517 with the drainage basin
521. Only when the spout 517 is directed over the entrance, which
is occupied by a pressurizing unit 523 in FIG. 15, will the pump
head 515 have the ability to be depressed freely. Even where the
spout 517 is not directly over the opening into the integral
internal reservoir (not shown in FIG. 15), any dispensed
concentrate will drain into such opening, assisted by the drainage
basin 521. An upper edge 525 of the drainage basin 521 radially and
blockingly "tracks" the spout 517 throughout the portion of its
radial pivot ability when it is not nearest the area within the
drainage basin 521 which is shown in FIG. 15 to be occupied with
the pressurizing unit 523.
[0099] The radial distance of the upper edge 525 is seen to engage
the spout 515 between its plunger 527 and spout tip 529. It is to
be emphasized that upper edge 525 may have a radially expanded
distance to simply catch any drips from the spout 517 to direct
those drips to the center opening (not shown in FIG. 15), or the
spout 517 may have a reduced radial distance. In this case, the
height of the upper edge 525 may be increased to block generally
all but deliberate access to the pump head 515. In an alternative
configuration the height of the pump head 515 may be lowered,
relative to the upper edge 525, to further prevent inadvertent
dispensing of concentrate. The rim 525 of the drainage basin 521
has an expanded radius portion surrounding the pressurizing unit
523 of which the pump handle 523 is visible in FIG. 15.
[0100] Also seen extending to one side of the body 503 is a hose
connection 531. Drainage basin 521 is also seen as having a lower
collar 533 which may form a partial or total support for the
drainage basin 521. A safety relief valve 535 is also seen on the
body 503.
[0101] Concentrate bottle 507 is shown as being supported by a
shelf extension 541 extending from a lower portion of the body 503.
Structures to be shown will illustrate some possible structure to
assist holding concentrate bottle 507 in place. Also seen is an
indented area 543 which defines the body 503 legs or stability
projections.
[0102] Referring to FIG. 16, a partially exploded view of the
integrated pressurizable applicator 501 is shown with the
concentrate container system 505 in a removed and exploded
position. The concentrate container 507 is seen as a generally
cylindrical container having an upper opening 555 surrounded by
threads 557 on a circumferentially indented land 559. From the land
559 the sides of the concentrate container 507 is generally
linearly cylindrical, terminating in a curved transition 561 to a
flat bottom 563. A rim 565 exists at the top of the land 559 which
is preferably enabled to accept a sealing member (not shown) and
which is to be further illustrated with respect to a concentrate
system.
[0103] A sealing member will preferably be of the type which
adheres to an upper rim and which can be either punctured or peeled
away. As will be shown, the integrated pressurizable applicator 501
utilizes a concentrate container system 505 which minimizes human
contact with the concentrate and minimizes spillage. In the
configuration shown, the puncturing of any covering seal will occur
at its center due to the generally concentric nature of the
concentrate container system 505.
[0104] The neck unit 509 has a set of internal threads adjacent its
underside for engagement with threads 557 of the concentrate
container 507. Neck unit 509 extends upwardly to a land 569 having
threads 571. Land 569 has an opening 573 at its upper end. The neck
unit 509 acts as an adapter to the concentrate container 507, and
can differ as needed to accommodate different configurations of
pump sets having different connection fittings. In the alternative
a single solid container can be utilized.
[0105] To the right of the neck unit 509 and concentrate unit 507
is a pump set 575 which includes a boss 577 above the collar 513,
and a main housing 579 below the collar 513. Below the main housing
579 is a pickup tube 581 having a lower end 583 which is cut at an
angle to form a sharp tip. Also seen is the fact that the plunger
527 extends down into the boss 577.
[0106] The concentrate container 507 is seen to fit into a curved
space 585 formed by a portion of the outside of the body 503. Space
585 has a projection 587 which engages an indentation (not shown)
on the concentrate container 507. The curved space 585 leads down
to a shelf 589 which supports both the concentrate container 507
and an upward button protrusion 591, which similarly fits into a
small indentation (not shown) on the concentrate container 507.
Each of the members including projection 587 and upward button
protrusion 591 limit the movement of the concentrate container 507
out of the curved space 585 by providing a general orthogonal entry
into the body of the concentrate container 507.
[0107] Changing of the concentrate container 507 is had by bringing
the bottom outward and over the relatively low height upwardly
projecting button protrusion 591. The more upwardly located
connection with the projection 587 enables a reduced removal angle.
Removal can be completed by either having the pump set 575 lowered
and angled out so that the spout 517 can clear an opening (not yet
shown) in the drainage basin 521. In the alternative, the collar
can be threadably removed from the threads 571 by turning the boss
577 from within the drainage basin 521 to remove the pump set 575.
After removal of the pump set 575, the empty concentrate container
501 with its attached neck unit 509 can be can be removed by either
urging the bottom or the top of the concentrate container 507
laterally away from the body 503.
[0108] Referring to FIG. 17, a sectional view of the integrated
pressurizable applicator 501 is seen. The details of the
pressurizing unit 523 are not shown beyond the partial and slight
detail of the handle shape. Typically this pressurizing unit 523
threadably disengages internally from a neck 597 of the body 503 by
turning the handle seen at the top of pressurizing unit 523 from
either a locked position or a position of maximum angular
displacement in one direction. In the unlocked (or un-threaded in
the case of a threaded hold down) position, a handle is usually
free to be raised and lowered to introduce pressure into a
reservoir 599.
[0109] As can be seen, the neck 597 forms an anchor to which the
lower collar 533 is attached. Attachment may be by close fit, pin
lock, gluing or any other acceptable method. In some of these
methods, the drainage basin 521 may be removable. In the
configuration shown, the locking down of the pressurizing unit 523
also causes the drainage basin 521 to be locked down and otherwise
supported.
[0110] To the right of the lower collar 533, the drainage basin 521
can be seen to have an opening 601 through which the boss 577 of
the pump set 575 is seen to immediately extend. Depending upon the
size of the pump head 515, it is possible to angle the concentrate
container 507 away from the body 503 with the drainage basin 521
still in place, and allow the plunger 527 to pass downwardly
through the opening 591 without having to disconnect the pump set
575 from the concentrate container 507. The ability and
desirability to do this may depend not only on the overall size of
the pump head 515, but also the height and diameter of the material
surrounding the opening 601. Further, the material surrounding the
opening 601 can be adjusted to engage the boss 577 or even the top
of the collar 513 to provide further support to the drainage basin
521.
[0111] As can be further seen, the concentrate container 507 is
held in place by the projection 587 extending into an indentation
605. Similarly, upward button protrusion 591 is seen protruding
into an indentation 607 located at the bottom center of the
concentrate container 507 and located at the center of generally
flat bottom 563.
[0112] Referring to FIG. 17, a more complete exploded view of the
concentrate container system 505 illustrates some of the
flexibility involved with the use of a wide mouth concentrate
container 507 along with a neck unit 509. As can be seen, the wide
mouth concentrate container 507 may be supplied with a sealing
plastic or foil or other thin planar sealing member 621 which
engages the upper rim 565 of the circumferentially indented land
559. Above the foil member 621, and as an option, a reinforcement
ring 623 having a smaller central aperture 625 is seen. The
reinforcement ring 623 is especially useful for concentrating any
puncturing forces from the pickup tube 583. Concentration of
puncture forces will prevent lateral wide tearing of the foil
member 621, and will prevent stretching of the surrounding areas of
the foil member 621. This can be particularly important if some
sealing is desired around the pickup tube 583. The reinforcement
ring 623 smaller central aperture 625 gives the ability to (1)
concentrate puncture area, (2) concentrate puncture forces, (3)
limit tearing to a small area, and (4) provide some sealing about
the pickup tube 583. The reinforcement ring 623 can be made of
flexible material to further accomplish this task.
[0113] Above the neck unit 509, a smaller diameter sealing plastic
or foil or other thin planar sealing member 631 is seen. Where a
small area of material is provided, and depending upon the
selection of material, a similarly small reinforcement ring 623 can
be eliminated. The user can be supplied with a bottle having the
dimensions of the combined concentrate container 507 and neck unit
509 or the user can be supplied with a simple concentrate container
507, especially sealed with a foil member 621 and optional
reinforcement member.
[0114] It is believed that where a liquid bottle is supplied, a
single bottle with a small opening 573 would be desirable. Where a
powder or dehydrated mixture is supplied, the concentrate container
507 may be supplied alone. This may include the case where water or
other fluid is added to an un-dissolved powder. In both cases the
system provides maximum flexibility to users, manufacturers, and
concentrate suppliers.
[0115] Referring to FIG. 19, a further embodiment is seen as a
gravity type applicator 651 which has features which are more
centered and vertically oriented. A concentrate container 653 is
seen a separated from the gravity type applicator 651. Concentrate
container 653 is vertically taller and thus has a little additional
volume capability for a given set of other dimensions.
[0116] The floor surface 393 and generally vertical, curved rear
surface 397 seen in gravity type applicator 301 is replaced by a
pure vertical axis horizontal indentation 655 which may have no
floor surface. A single projection 657 is seen extending from a
point generally near the middle of the horizontal indentation 655
and matches bore 659 shown in phantom at the rear of the
concentrate container 653. Aside from support had just below the
base collar 359, the bore 659 connection with the projection 657
provides the only other support for the concentrate container 653.
Note also that the concentrate container 653 has been located more
rearwardly than the position of concentrate container 303 with
respect to gravity type applicator 301. This offers different
advantages of enabling user contact directly with the bottom of the
concentrate container 653, as well as a more centered center of
gravity profile.
[0117] Projection 657 is seen as being cylindrical, but need not
be. Projection 657, as well as bore 659, can be angled upwardly to
obtain a better hold on the concentrate container 653. Further, the
projection 657/bore 659 holding system can be supplemented by other
holding structure possibly in conjunction with other
structures.
[0118] In addition, a matching one piece holding and flow directing
structure 661 is provided which includes a curved portion 663 and
an enclosed guide structure 665 having a side opening 667. The
enclosed guide structure 665 has a bottom opening (not shown)
preferably with a sleeved extension extending through a matching
opening in a top surface 671 upon which the guide structure 665 is
mounted. This enables dispensed concentrate to fall directly into
the inside of the upper reservoir portion 307 to further eliminate
surfaces, especially surfaces which are slightly horizontal which
might come into contact with, and delay the entry of concentrate.
The entry of the spout 357 into the opening 667 is by a slight
turning motion, similar to that seen in gravity type applicator
301. The flow directing structure 661 provides a more protected
structure to both guard against inadvertent actuation as well as
some added degree of isolation of the concentrate. Rivets 675 are
seen holding the flow directing structure 661 atop the top surface
671.
[0119] A more compact sprinkle screen assembly 681 is seen having a
housing 683. Referring to FIG. 20, a view of the detached compact
sprinkle screen assembly 681 is seen having a cover 685 having side
pinned projections 687. The cover 685 has a series of holes 689 to
enable a sprinkles flow when the cover 685 is rotated to a covering
position within the housing 683. The wall thickness of the
cylindrical portion 323 should ideally be thin enough to insure
that the cover 685 swings freely open. Detent notches both
forwardly and rearwardly adjacent the housing 683 near the pinned
projections 687, will enable the cover 685 to be held in the open
position.
[0120] Referring to FIG. 21, a side perspective view of a gravity
type applicator 701 has a few additional features of note. At the
left, a gravity type applicator 701 is seen to have a recessed
sprinkle screen assembly 703 to provide additional protection for
the sprinkle cover 685. A matching one piece holding and flow
directing structure 705 includes a neck reinforcement partially
surrounding boss 707 to provide a more strengthened lock between
the base collar 359 and top of a concentrate container 711. The
terminations of the boss 707 are wedge shaped which enable the gap
between the base collar 359 and top of a concentrate container 711
to be used to mount it on the wedge shaped boss 707 to get a good
lock on the holding of the concentrate container 711.
[0121] The concentrate container 711 includes a pair of wedge
shaped projections 713 near its base, one of which is seen in FIG.
1. The wedge shaped projections 713 slip past a matching pair of
interference structure projections (not shown in FIG. 21) on the
inside of the vertical axis horizontal indentation 655. The wedge
shape of the projections 713 assist in ease of locking and in
maintaining the concentrate container 711 into place. As before,
the spout 357 of the manual pump 355 is guided into the side
opening 667 as the concentrate container 711 is loaded onto the
matching one piece holding and flow directing structure 705. Also
note that as a variation, a set of volumetric indicator marks 717
are located on the side of the concentrate container 711.
[0122] Referring to FIG. 22, a further variation on the matching
one piece holding and flow directing structure 705 is shown. A
unitary combination matching one piece holding, rim and flow
directing structure 721 is shown in exploded view over the gravity
type applicator 701 seen in FIG. 21. The combination matching one
piece holding, rim and flow directing structure 721 may be
particularly advantageous for cases where the large top opening 305
is not as finished as would be desired or where the top opening 305
needs to be utilized for additional stability.
[0123] The unitary combination matching one piece holding, rim and
flow directing structure 721 has a downwardly directed flange 723
which fits into the opening 305 which helps to stabilize and
register the unitary combination matching one piece holding, rim
and flow directing structure 721. A pair of apertures, including
the aperture 725 which is seen on the unitary combination matching
one piece holding, rim and flow directing structure 721 are used to
hold it in place. With the additional stabilization of the flange
723, a lesser number of apertures may be necessary. A pair of
apertures 727 are seen on the upper surface 671 of the gravity type
applicator 701 which align wit the apertures 725.
[0124] In FIG. 22, one of two vertical projections 731 are seen
just inside the lower extent of the vertical axis horizontal
indentation 655.
[0125] Referring to FIG. 23, a sectional view taken along lines
23-23 of FIG. 21 shows a recessed sprinkle screen assembly 703
which is oriented to open by pivoting in one direction only. A
cover 741 has water flow apertures 743 and is mounted to pivot
adjacent an interference projection 745. On one side of the pivot
of the cover 741, an inside portion of the recessed sprinkle screen
assembly 703 is provided as a sweeping surface 751, so that the
cover 741 will sweep toward the main body of the gravity type
applicator 701. At the other side of the pivot of the cover 741, an
inside portion of the recessed sprinkle screen assembly 703
includes a stop lip 753 which prevents motion of an abutting
portion of the cover 741 from movement in the direction of the
gravity type applicator 701.
[0126] By providing movement in one direction only, a closer
tolerance can be provided to enable the cover 741 to become more
easily fixable in the open position. The interference projection
745 is used to keep the cover 741 in the open position. It is
preferable to mark the cover 741 to indicate the direction of
movement by pressing the side of the cover 741 nearest the sweeping
surface 751. Further, an extended forward portion of the housing of
the recessed sprinkle screen assembly 703 provides additional
protection for the cover 741 when it is in the open position.
[0127] Further, the flexibility for sealing will provide
manufacturers and users with new options for recycling. By
standardizing the containers in a way which maximizes their usage,
recycling is facilitated. Recycling includes cleaning, re-filling
with more concentrate and re-selling. The concentrate container
system 505 also facilitates the use of colors to identify different
types of concentrate.
[0128] Referring to FIG. 24, a one piece gravity type applicator
801 is seen as having a reservoir opening 803 located underneath an
arching handle 805. As before, the arching handle 805 assists in
balancing of the gravity type applicator 801 throughout the range
of fullness of the gravity type applicator 801 as the diluted
nutrient is dispensed. FIG. 24 illustrates an integrally formed
interfitting space 807 which is formed as if "pressed into" the
side of the gravity type applicator 801. Near the bottom of the
interfitting space 807 a slight shelf 809 is seen, but displaced
upwardly from the lowermost portion of the applicator 801. In the
upper left side of the interfitting space 807, a slot 811 is
seen.
[0129] To the left of the one piece gravity type applicator 801, a
nutrient concentrate container 815 is seen. Nutrient concentrate
container 815 has two pairs of scalloped protrusions, one pair of
which is seen in FIG. 24 as a pair of collinear scallops 817
located to the right of the front midline of the nutrient
concentrate container 815, and toward the interfitting space 807 of
the gravity type applicator 801. A mating set of indentations in
the interfitting space 807 will be shown in subsequent figures.
[0130] Also seen on the nutrient concentrate container 815 is a
pump assembly including a threaded cap 819, and pump head 821 with
a spout 823 which may optionally have a downwardly extending
distalmost extent as the shape of a hawk bill. A downward hook or
hawk bill shape insures that when the pump head 821 is in the down
position that some attachment support for the nutrient concentrate
container 815 will be had from the bottom of the slot 811 through
the spout 823. interfitting space 807 which is formed as if
"pressed into" the side of the gravity type applicator 801. which
is formed as if "pressed into" the side of the gravity type
applicator 801. This is especially true if the pump head 821 is not
spring urged upward with respect to the threaded cap 819. In this
mode of operation, the operator will manually lift the pump head
821 upwardly to draw a volume of concentrate from within the
nutrient concentrate container 815 and then push down on the pump
head 821 to dispense the liquid through the end of the spout 832
located on the inside of the gravity type applicator 801, through
the slot 811. Alternatively, the pump head 821 may be spring urged
upward with respect to the threaded cap 819, and it is preferable
that any such spring be strong enough to avoid inadvertent
activation of the pump head 819, and yet not so strong as to cause
any increased change of dislodgement of the nutrient concentrate
container 815 from the interfitting space 807 when the pump head
819 is activated.
[0131] Referring to FIG. 25 a perspective view of the gravity type
applicator 801 seen in FIG. 24 is seen, but with the nutrient
concentrate container 815 seen in an engaged position with respect
to the applicator 801. A finger space 825 is formed by the
attachment of the nutrient concentrate container 815 in an upward
position, atop shelf 809 of the applicator 801. The finger space
825 assists the user in grasping and pulling the nutrient
concentrate container 815 from engagement with the interfitting
space 807. The other structures of the one piece gravity type
applicator 801 in common with the embodiments seen in FIGS. 1-23
will not be further identified for expediency. In the embodiment of
FIGS. 24 & 25 the structure above the reservoir opening has
been dispensed with, but the reservoir into which the opening 803
opens cannot be filled above the height of the lowest extent of the
slot 811 or else water and nutrient would leak into the
interfitting space 807 between the one piece gravity type
applicator 801 and the nutrient concentrate container 815. The
elimination of any spout guide structures atop the nutrient
concentrate container 815 makes for a simpler construction and more
aesthetically pleasing lines.
[0132] Referring to FIG. 26, a top view of the gravity type
applicator 801 seen in FIGS. 24 & 25 emphasizes the shape of
the formed interfitting space 807 and illustrating the guide slot
811 and lower shelf partial support 809.
[0133] Referring to FIG. 27 is a bottom view of the gravity type
applicator 801 seen in FIGS. 24-26 emphasizes a continuous
peripheral support structure 827 for providing for added stability
about the bottom periphery of the applicator 801. The peripheral
support structure 827 insures that the applicator 801 will not tilt
in the direction of the interfitting space 807 if the area under
the interfitting space 807 were aligned with an irregular support.
Further, the shape of the peripheral support structure 827 provides
an ergonomically compatible hand hold for the user in manipulating
the applicator during the watering and feeding process. As seen,
the peripheral support structure 827 surrounds a generally flat
area 829.
[0134] Referring to FIG. 28, a perspective view of the gravity type
applicator seen in FIGS. 24-27 with the concentrate container 815
removed to better emphasize the structures of the interfitting
space 807 of the applicator 801. A pair of indentations 831 on
opposite sides of the interfitting space 807 (only one pair is seen
in FIG. 28) interfit with the pair of collinear scallops 817 on
each end of the nutrient concentrate container 815 (only one pair
of which were seen in FIG. 24). The indentations 831 accommodate
the pair of collinear scallops 817 to form a stable interference
fit to hold the nutrient concentrate container 815 within the
interfitting space 807 and onto the slight shelf 809. The
combination of the pair of collinear indentations 831 and matching
the pair of collinear scallops 817 and the slight shelf 809 act to
secure the nutrient concentrate container 815 securely within the
interfitting space 807 of the applicator 801.
[0135] FIG. 29 is a side elevational view of the gravity type
applicator 801 seen in FIGS. 24-28 and emphasizing the vertical
profile of the interfitting space 807 for supporting the nutrient
concentrate container 815. Only a slight portion of both pairs of
indentations 831 can be seen on opposite sides of the interfitting
space 807. Also seen is the height of the slot 811 and how close it
is to the top edge of the reservoir opening 803. An optional fill
line 833 seen on the interfitting space 807 as an aid to users as
an optical mark on filling to insure that the fill level does not
exceed the bottom of the slot 811.
[0136] The nutrient concentrate containers 815 can still be
interchanged, but the size of the nutrient concentrate container
815 is such that a user can be facilitated in using the one piece
gravity type applicator 801 far from a central station or service
vehicle such as watering the plants within a building, using the
water sources throughout the building without the need for
returning to the vehicle or central station. Further, the nutrient
concentrate containers 815 is so configured that it may be supplied
as seen in FIG. 24 in a ready-to-go container, possibly with a clip
to hold the pump head 821 into a locked "up" position. In this
manner, no special handling of the plant nutrient container is
needed. Where the pump portion is to be re-used, the nutrient
concentrate containers 815 can be provided with seals as described
for FIGS. 1-23.
[0137] Referring to FIG. 30, a perspective view of a pressurized
applicator 851. Pressurized applicator 851 may have a special
surface 853 for providing some accommodation for a concentrate
bottle or other structure. A hose fitting 855 is shown in broken
line format and which would normally continue with a hand held
sprayer, valve trigger and the like to enable the applicator to be
easily utilized. At the top of the pressurized applicator 851, a
handle and pump assembly 857 is seen as having a handle 861 and a
air pressurization unit 863. As is known in conventional
applications, the a handle and pump assembly 857 is threadably
removable from the remainder of the pressurized applicator 851
typically by turning the handle 861 through its engaged and
disengage lock position to cause the pump assembly 857 to become
threadably removed from the pressurized applicator 851. This can
typically only be performed manually once the pressurized
applicator 851 has zero internal pressure. The handle 861, once the
pump assembly 857 is in place, can also assume a lock position so
that the pressurized applicator 851 can be carried without
extending the pump rod to which the pump handle is attached.
[0138] A drainage structure 865 is seen as surrounding the upper
part of the air pressurization unit 863. Below the drainage
structure 865, the pressurized applicator 851 has a neck 867 which
is only partially seen in the Figures. The neck 867 assists in
vertical stabilization of other structures. Many conventional
pressurized applicators hav a naturally occurring neck 867 and even
where no neck occurs other structure can be had for vertical
stabilization.
[0139] A concentrate container support 871 is typically secured
around the neck 867. The concentrate container support 871 has an
overall "X" shape with the top space for garnering support from the
neck 867 and the bottom, opposite space for lending support to a
concentrate applicator bottle. A specialized groove 873 will be
used to fit a male and female extension adapter which can be used
with any concentrate bottle and lid to enable it to be supported by
the concentrate container support 871.
[0140] The concentrate container support 871 may also have a spout
guide and lock structure 875 which can be permanently or
temporarily fittable into the concentrate container support 871.
Attachment may be accomplished by ultrasonic welding, gluing,
melting, or by injection molding of the concentrate container
support 871 into a mold with the spout guide and lock structure 875
in place. This spout guide and lock structure 875 permits the spout
of a concentrate dispenser to move up and down when the concentrate
spout is moved to a position over the center of the drainage
structure 865.
[0141] The shape of the spout guide and lock structure 875 is that
of an "inverted U" shape in which a first portion of the width of
the "U" shape extends to a first height, while the remainder of the
width of the "U" shape extends over a second portion to a second
height less than the first height. A concentrate spout structure
under the first portion of width of spout guide and lock structure
875 will be enabled to extend upwardly and downwardly throughout a
full range (if arranged at the proper height) from its bottom most
position to its topmost position to enable a full metering stroke
of dispensed liquid. Conversely, a concentrate spout structure
under the second portion of width of spout guide and lock structure
875 will be enabled to neither extend upwardly nor downwardly
(again if arranged at the proper height) and remain in a locked
position.
[0142] The spout guide and lock structure 875 has a curved shape
when viewed from above, to accommodate a structure which pivots.
The spout guide and lock structure 875 could be made straight and
simply mechanically engage different portions of the spout. The use
of a curved structure, however, will help to keep the contact upon
a restrained structure consistent and even allow selection of the
wear point and its reinforcement.
[0143] As can be seen, the special surface 853 is positioned fairly
closely adjacent the innermost curvature of an inner surface 877
which is immediately next to the specialized groove 873. Other
embodiments may provide for a longer or shorter concentrate
container support 871. Where concentrate container support 871 is
longer, it may be that no special surface 853 is needed. Some of
the criterion will depend upon the overall shape of the pressurized
applicator 851, the use of an alternatively located carry handle
(which may exist in addition to the pump supported handle 861), and
the shape of a concentrate bottle. A pair of structures 879 may be
made integral with the pressurized applicator 851 and may be used
to hold the concentrate container support 871 in place. Threaded
members at the rear of the structures 879 may extend through
structures 879 and into the concentrate container support 871, as
one way to attach concentrate container support 871 to the
pressurized applicator 851.
[0144] FIG. 31 is a perspective view similar to that seen in FIG.
30 but with the air pressurization unit 863 removed and with a
concentrate bottle 891 assembly on approach. Concentrate bottle
assembly 891 may include a container 893, a collar adapter 895 with
circumferentially outwardly extending land 897 which is
complementary to the specialized groove 873. The use of a specific
sized groove 873 and a matching land 897 limits the vertical area
of contact and helps to lock the container 893 into place and make
it less likely to become dislodged upon application of a twisting
force. In other words, any twist applied about the collar adapter
895 will be transmitted and absorbed by the concentrate container
support 871 rather than looseness between the container 893 and the
concentrate container support 871.
[0145] The specialized groove 873 also more rigidly sets the height
and position of the collar adapter 895 and any pump dispenser unit
899 with respect to the concentrate container support 871, spout
guide and lock structure 875, and the height of any drainage
structure 865 present.
[0146] FIG. 31 illustrates the concentrate container 893 being
moved into place with respect to the concentrate container support
871 and in particular with the circumferentially outwardly
extending land 897 of the collar adapter 895 aligned with the
specialized groove 873 of the concentrate container support 871. A
spout 901 of the pump dispenser unit 899 is directed through the
spout guide and lock structure 875 which will enable the spout
guide and lock structure 875 to govern the operation of the pump
dispenser unit 899 in accord with the pivotal position of the spout
901. Once the concentrate container 893 is in place with the spout
901 extending through the collar adapter 895, the pivotal rotation
of the spout 901 will be restricted to pivoting within the width of
the vertical members of the spout guide and lock structure 875.
[0147] Referring to FIG. 32, a perspective view showing the
concentrate bottle 893 locked into place by its collar adapter 895
is shown. The tip of the spout 901 is directed over the drainage
structure 865 in a position to facilitate dispensing of the
concentrate from the concentrate bottle 893. In this position, the
pump dispenser unit 899 is free to be raised, either manually or by
spring action, to a position in which the spout 901 contacts the
horizontal portion of the uppermost extent of the spout guide and
lock structure 875.
[0148] Referring to FIG. 33, a perspective view the pump dispenser
unit 899 in its uppermost position is shown. This is the position
of the pump dispenser unit 899 just before liquid concentrate is
dispensed. When the pump dispenser unit 899 is brought back to the
position shown in FIG. 32, which liquid concentrate is dispensed.
Typically, the pump dispenser unit 899 will have a liquid
concentrate delivery characteristic such that one full horizontal
stroke will dispense the correct amount of concentrate. If not, it
is preferable for the proper amount of concentrate to be delivered
in an integer number of full strokes.
[0149] Referring to FIG. 34, a perspective view the pump dispenser
unit 899 with its spout 901, after dispensation, being pivoted into
the no-drip storage position under the spout guide and lock
structure 875, is shown. Note the FIG. 34 depicts the pressurized
applicator 851 just after dispensing concentrate and before the Air
pressurization unit 863 has been replaced. In FIG. 34, even if the
pump dispenser unit 899 is spring urged to an upward position, the
spout guide and lock structure 875 acts to hold the pump dispenser
unit 899 down and prevent its inadvertent upward motion.
Inadvertent upward motion might otherwise be followed by
inadvertent downward motion and a dispensing of concentrate outside
of the drainage structure 865, and thus spillage.
[0150] Referring to FIG. 35 a perspective view of the pressurized
applicator 851 is shown in which the concentrate pump dispenser
unit 899 and spout 901 is shown in a carriage position, where the
pump dispenser unit 899 and spout 901 are vertically locked into
place. Note the FIG. 34 depicts the pressurized applicator 851 just
after concentrate pump dispenser unit 899 and spout 901 have been
moved to one side and after the air pressurization unit 863 has
been replaced. The air pressurization unit 863 provides some
physical interference against the pivoting of the concentrate pump
dispenser unit 899 and spout 901 to a position which would enable
the pump dispenser unit 899 and spout 901 to pivot to a position
with respect to the spout guide and lock structure 875 in which the
concentrate pump dispenser unit 899 and spout 901 could be
vertically raised to a position in which downward motion and
inadvertent dispensing of concentrate could occur.
[0151] Referring to FIG. 36, an exploded view of the concentrate
bottle assembly 891 emphasizing the extent of the pump dispenser
unit 899 and pickup tube 903 with its cannulated tip 905. The
cannulated tip 905 facilitates the use of the pump dispenser unit
899 with a concentrate container 893 having a sealed top in order
to minimize spillage and eliminate the necessity to handle or come
into contact with the concentrate.
[0152] Further details of the collar adapter 895 are seen as
including an upper threaded member 907 and a lower threaded member
909 with the internal threads shown in dashed line format. A
threaded section 911 is seen on the concentrate container 893. The
pump dispenser unit 899 may preferably have an internal thread
section shown in dashed line format as thread section 913 which
interfits with thread section 907.
[0153] The collar adapter 895 is primarily present to provide
circumferentially outwardly extending land 897. However, collar
adapters 895 can also be used to provide threaded sections 909 and
907 which are of different size and which can provide the
circumferentially outwardly extending land 897 along with the
provision of an adaptation for differing thread size. In other
words, threaded section 909 can be larger or smaller than thread
section 907 in order to provide mating adaptation between pump
dispenser units 899 which are of a different size than concentrate
containers 893 with which they are utilized.
[0154] Referring to FIG. 37, further details of the concentrate
container support 871 are seen. A pair of generally flat opposing
sections 917 are seen which may be angled slightly outwardly to
facilitate entry of collar adapter 895. A vertically short length
of inner surface 919 is seen below the specialized groove 873. The
inner surfaces 919, specialized groove 873, and inner surface 877
form part of a concentrate bottle opening 921. The concentrate
bottle opening 921 has an arc which extends for more than
180.degree..
[0155] The structural components of the concentrate container
support 871 are seen as having a midline plate 923 reinforced by a
series of connecting vertical walls 925 only some of which are
numbered. An outside wall 927 acts structurally in the same manner
as many of the other vertical walls 925.
[0156] One of the outside vertical walls 927 and one of the inside
vertical walls 925 carry cylindrically reinforced bores 931 and 933
for the ends of the spout guide and lock structure 875 to fit. At
the end of the concentrate container support 871 opposite the
concentrate bottle opening 921 is a neck opening 941. As stated
earlier, the attachment to a pressurized applicator 851 could be
through structures 879. In this event, other cylindrical supports
such as cylindrical support 943 can be seen in FIG. 37 for
accepting a securing threaded member. The cylindrical support 943
seen is its outside partially supported by one of the inside
vertical walls 925 and one of the outside walls 927.
[0157] In the alternative, and still using the cylindrical support
943, a collar 945 can be used to form a complete circular enclosure
to fit about the neck of any container. Threaded members 947 can be
used to secure the cylindrical support 943 to the concentrate
container support 871 and about the neck of any container, or to
secure the concentrate container support 871 to support structures
879 as are seen extending from pressurized applicator 851.
[0158] Also seen integral with and extending slightly from the
concentrate container support 871 are a pair of ears 951 each
having a vertical bore 953. Cylindrical ears 951 and the vertical
bores 953 are simply further structures which can be utilized to
cause the concentrate container support 871 to be attached to
another structure, and especially a structures in approximate
conformity with the neck opening 941.
[0159] Referring to FIG. 38, an expanded view illustrates another
manner in which concentrate container support 871 can be attached
to another structure, especially having a neck 867. A rubber strap
961 can have a fitting end 963 supporting a swivel hook 965. An end
967 of the swivel hook 965 can be bent slightly to enable it to
extend through the vertical bores 953 of the ears 951 and
stabilized when placed under tensile strength. The strap 961 can be
stretched around the neck 867 and hooked into the ears 953 to form
a stable, solidly connected configuration.
[0160] Referring to FIG. 39, a sectional view of the collar adapter
895 seen in FIG. 38 illustrates an adaptive role where the threaded
opening for the concentrate container 893 is smaller than the
threads 907 presented to the pump dispenser unit 899. In addition
to the structures already seen, a cylindrical bore 971 leads
directly into the threaded section 909. When the collar adapter is
connected to the concentrate container 893, the cylindrical bore
971 will lead directly through an internal bore concentrically on
the other side of the threaded section 911.
[0161] Referring to FIG. 40, a plan view of the spout guide and
lock structure 875 seen in isolation enables further identification
of its structures. The spout guide and lock structure 875 may be of
one continuous length of metal rod and having a pair of ends 981
and 983. A first section 985 which extends the height of the spout
guide and lock structure 875. A short horizontal second section 987
is followed by a short, nearly half height third section 989. The
space between the first section 985 and third section 993 is
sufficiently wide that the spout 901 can slide freely up and down.
Following, the third section 989 is a short horizontal fourth
section 991. The length of the section 991 will determine,
especially based upon the distance the spout guide and lock
structure 875 is located from the center of pivot of the pump
dispenser unit 899, the extent to which the spout 901 can be
pivoted to one side, underneath the lock down restriction of
section 991. Fourth section 991 is followed by a fifth section 993
which terminates at end 983.
[0162] While the present invention has been described in terms of a
system for providing convenient metered concentrate with respect to
a dilute dispenser system, the principles contained therein are
applicable to other types of systems.
[0163] Although the invention is derived with reference to
particular illustrative embodiments, many changes and modifications
of the invention may become apparent to those skilled in the art
without departing from the spirit and scope of the invention.
Therefore, included within the patent warranted hereon are all such
changes and modifications as may reasonably and properly be
included within the scope of this contribution to the art.
