Definitions
- the invention relates to systems for dispensing a concentrated chemical into a dilution tank. Specifically, the invention relates to systems for hermetically dispensing and diluting a concentrated chemical which includes a means for hermetically rinsing the concentrated chemical container.
- the shipping containers for concentrated chemicals also present a significant problem.
- the residual concentrated chemical inherently retained within an otherwise empty container pose a significant threat to the environment if the container is simply discarded as routine refuse. While appropriate rinsing of the container can substantially alleviate this problem, such a rinsing process further exposes an end-user to the concentrated chemical.
- the system includes (i) a means for hermetically providing fluid communication from the container to the dilution tank, (ii) a means for unsealing the container after the container has been hermetically coupled to the fluid communication means, (iii) a means for hermetically providing fluid flow from a source of water into the dilution tank, and (iv) a means for hermetically directing fluid flow from the source of water into the container for rinsing residual chemical from the container into the dilution tank.
- the system prevents exposing either the concentrated or diluted forms of a chemical to the atmosphere during dispensing of the chemical, dilution of the dispensed chemical, and rinsing of the empty container.
- the system includes (i) a conduit having a main passageway which defines a main run and which is operably couplable at an upstream end to a container of concentrated chemical so as to sealingly place the main run in fluid communication with the container, (ii) a first fitting downstream from the conduit which includes [aa] a main passageway in fluid communication with main passageway of the conduit so as to continue the main run, and (bb) a branch passageway defining a branch run which is in fluid communication with main run so as to define a junction of the main run and the branch run, (iii) a first main valve located within the main run between the upstream end of the conduit and the junction of the branch run and the main run which is operable in a first position for opening the main run to fluid flow and operable in a second position for
- valves permit flow control of concentrated chemical and water through the system and cooperate with the coupling for permitting disconnection of the container from the dilution tank without exposing the user- to ' the concentrated chemical remaining in the container or the diluted chemical retained within the dilution tank.
- Figure 1 is a perspective view of one embodiment of the invention.
- Figure 2 is an exploded perspective view of the invention depicted-in Figure 1.
- Figure 3 is a cross-sectional side view of the primary conduit portion of the invention depicted in Figure 1 taken along line 3-3.
- Figure 4 is a perspective view of one embodiment of a bracket useful for supporting a contaner attached to the invention above a dilution tank.
- the system which I have developed may be utilized to hermetically dispense substantially any chemical and dilute the chemical with substantially any solvent. However, for the purposes of facilitating discussion of the system, the system will be described with respect to the dispensing of a concentrated chemical into a dilution tank where the dispensed chemical is diluted with water.
- concentrated chemical may flow through the system in both directions depending upon the vertical positioning of the system with respect to the container (above/belo )
- the components of the system will be referenced with respect to an upstream end and a downstream end in accordance with the flow of concentrated chemical through the system when the concentrated chemical is being dispensing from the container into the dilution tank.
- Concentrated chemicals such as pesticides and herbicides are generally sold in glass or plastic containers 600 which are provided with a single opening 604 through the top 601 of the container 600.
- the opening 604 is typically protectively sealed by a mylar film (not shown) bonded to the periphery of a threaded collar 605 surrounding the opening 604.
- the system 100 provides for controlled hermetic dispensing of a chemical from a container 600 into a tank 500 and controlled hermetic dilution of the dispensed chemical in the tank 500.
- the system 100 also provides for hermetic rinsing of the container 600 when emptied with drainage of the residual chemical and rinse water into the dilution tank 500.
- a primary conduit 120 of the system 100 is operably attachable to a container 600 by means of an inner threaded cap 110 which encompasses an outer annular flange 122 at the upstream end 120a of the primary conduit 120 and threadably engages an outer threaded collar 605 surrounding the opening 604 in the container 600.
- the primary conduit 120 defines a main passageway 121 which is placed in fluid communication with the chamber 606 of the container 600 through the opening 604 in the container 600 when the cap 110 engages the collar on the container 600.
- the main passageway 121 through the primary conduit 120 initiates a main run for directing concentrated chemical (not shown) from the container 600 to the dilution tank 500.
- An inclined annular blade 123 is provided at the upstream end 120a of the primary conduit 120 surrounding the main passageway 121 through the primary conduit 120 for cutting the seal (not shown) which is secured over the opening 604 in the container 600.
- the annular blade 123 is recessed such that the seal is cut by the blade 123 only after the container 600 has been sealincly secured to the system 100 by the cap 110.
- the blade 123 is operable so that the central portion of the seal cut by the blade 123 remains attached to the container 600 and will not interfere with fluid flow through the system 100.
- a one-way breather valve 124 is provided through the primary conduit 120 for permitting aspiration of air into the container 600 during dispensing of concentrated chemical from the container 600.

- a first main valve 150 is threadably coupled to the downstream end 120b of the primary conduit 120 and the upstream end 170a of the main section 171 of the wye fitting 170 for controlling fluid flow through the main run upstream of the junction point 175.
- a second main valve 180 is threadably coupled to the downstream end 170b of the main section 171 of the wye fitting 170 for controlling fluid flow through the main run downstream from the junction point 175.
- a first branch valve 200 is coupled to the upstream end 170c of the branch section 173 of the wye fitting 170 for controlling fluid flow through the branch run.
- a triple branched crotch fitting 220 is threadably coupled through an adaptor 210 to the upstream end 200a of the first branch valve 200 at a second branch 222 of a crotch fitting 220.
- the first branch 221 of the crotch fitting 220 is coupling to a hose 700 which is in fluid communication with source of pressurized water.
- the third branch 223 is threaded to a reducer 230 which in turn is coupled to tubing 240.
- a second branch valve 227 is provided in the second branch 222 of the crotch fitting 220 for controlling fluid flow through the passageway 225 in the second branch 222.
- a third branch valve 228 is provided in the third branch 223 of the crotch fitting 220 for controlling fluid flow through the passageway 226 in the third branch 223.
- a primary coupling 160 is provided within the main run between the first main valve 150 and the wye fitting 170 which is operable in a first mode for permitting disconnection of the system 100 so as to create separate upper 100a and lower 100b portions of system 100 and operable in a second mode for sealing connecting the upper 100a and lower 100b sections of the system 100 so as to provide a continuous main run through the system 100.
- the male portion 162 of the primary coupling 160 is threadably engaged to the downstream end 150b of the first valve 150 while the female portion 161 of the primary coupling 160 is threadably engaged to the upstream end 170a of the main section 171 of the wye fitting 170.
- the female 161 and male 162 portions of the primary coupling 160 are sealingly connected and disconnected by a pair of clamping levers 165 which restrict the periphery of the female portion 161 when placed in an up position and expand the periphery of the female portion 161 when placed in a down position.
- a translucent receptacle 300 is threadably engaged to the downstream end 180b of the second valve 180 at a threaded inlet orifice 305 in the top 301 of the receptacle 300.
- the cavity 304 defined by the receptacle 300 is thereby placed in direct fluid communication with the container 600 through the main run of the system 100.
- the receptacle 300 includes a volumetric scale 307 along the side wall-30i- of the receptacle 300 for measuring the quantity of concentrated chemical dispensed through the system 100 and into the receptacle 300.
- the quantity of concentrated chemical dispensed into the receptacle 300 may be controlled by operation of the first main valve 150.
- a metering gauge 190 may be employed within the main run between the first main valve 150 and the receptacle 300.
- Such metering gauges 190 for in-line measurement of fluid flow are readily available form such suppliers an Great Plains Industries, Inc. of Wichita, Kansas.
- Placement of the metering gauge 190 upstream of the junction 175 of the main run and the branch run provides for measurement of only the quantity of concentrated chemical flowing through the main run while placement of the metering gauge 190 downstream from the junction 175 permits measurement of both concentrated chemical and diluting solvent passing through the main run.
- Concentrated chemical dispensed into the receptacle 300 is released from the receptacle 300 into the dilution tank 500 through an outlet orifice 306 in the bottom 302 of the receptacle 300.
- the outlet orifice 306 is sealed by a spring biased valve 350 which maintains the valve 350 in a closed position for preventing the flow of fluid from the receptacle 300 into the dilution tank 500.
- the spring biased valve 350 includes a supporting frame 354 forming a bubble over the outlet orifice 306 in the receptacle 300, a plug 352 over the outlet orifice 306 in the receptacle 300, a stem 351 with one end coupled to the plug 352 and the other end extending through a central orifice 355 in the frame 354, an annular gasket 353 surrounding the outlet orifice 306, and a spring 356 surrounding the stem 351 and retained between the plug 352 and the frame 354 for biasing the plug 352 towards the outlet orifice 306 and against the gasket 353.
- the frame 354 is securely attached to the bottom 302 of the receptacle 300.
- the spring biased valve 350 is forced against the bias and into an open position for releasing the contents of the receptacle 300 when the receptacle 300 is full inserted within a sleeve 400 which includes a central finger 452 for contacting the plug 352 of the spring biased valve 350.
- the sleeve 400 includes an inwardly extending guiding projection 407 mated for engagement within a guiding channel 310 in the sidewall 303 of the receptacle 300.
- the guiding channel 310 includes a lower longitudinal length 311, a lower lateral length 312, an upper longitudinal length 313, and an upper lateral length 314.
- the configuration of the guiding channel 310 is such that the spring biased valve 350 remains in the closed position when the guiding projection 407 is retained within the lower lateral length 312 of the guiding channel 310 but is forced into an open position by the finger 452 when the guiding projection 407 is retained within the upper lateral length 314 of the guiding channel 310.
- the guiding channel 310 is configured such that the guiding projection 407 may pass from the lower lateral length 312 to the upper lateral length 314 of the guiding channel 310 only by rotating the receptacle 300 with respect to the sleeve 400 after the projection 407 has travelled completely up the lower longitudinal length 311 of the guiding channel 310.
- the finger 452 is provided within the sleeve 400 as part of an independent and separate inset 450 which includes the central finger 452 and an annular base 451.
- the inset 450 is supported within the sleeve 400 by an inner annular shoulder 405 on the sleeve 400 which is proximate the bottom 402 of the sleeve 400.
- the base 451 of the inset 450 is configured to provide unrestricted passage of fluid through the inset 450 and into the dilution tank 500 while providing sufficient structural integrity to support the central finger 452 against the bias of the spring 356.
- the passageway 404 through the sleeve 400 is configured and arranged to sealingly engage the sidewall 303 of the receptacle 300 so as to prevent fluid flow between the receptacle 300 and the sleeve 400.
- the sleeve 400 is sealably secured within the opening 502 of a dilution tank 500 by an outer annular shoulder 408 proximate the top 401 of the sleeve 400 which engages the dilution tank 500 around the opening 502 through the dilution tank 500.
- a telescoping nozzle 130 is provided within the main passageway 121 of the primary conduit 120.
- the telescoping nozzle 130 includes a spray head 131 at one end for providing an effective rinsing spray pattern within the container 600.
- the telescoping nozzle 130 is coupled to the tubing 240 at the other end so as to provide for pressurized fluid flow to the spray head 131 from the source of pressurized water when the third branch valve 228 is open to fluid flow.
- the flow of .pressurized fluid through the tubing 240 and into the telescoping nozzle 130 causes the telescoping nozzle 130 to telescope into the container 600 and provide a rinsing spray within the container 600 to remove residual concentrated chemical from the container 600.
- the nozzle 130 is provided in telescoping form so that the nozzle 130 does not interfere with the initial unsealing of the container 600 by the annular blade 123 and provides a more effective rinse of the container 600 than obtainable by a single jet stream directed from inside the main passageway 121 in the primary conduit 120 into the container 600.
- the tubing 240 is connected to the telescoping nozzle 130 by means of a quick-release coupling 140 which includes a female portion 141 secured to the telescoping nozzle and a male portion 142 secured to the tubing 240.
