Definitions
- This invention relates to mixing paint components, such as colorants, tints and pearls, to create automotive paint formulas.
- the present invention is a fluid seal structure positioned between a pour spout and a linearly movable cover element of a paint container lid that can be secured to an original paint component container and is useable with a semi-automated system for dispensing paint components according to a desired paint formula.
- the fluid seal structure prevents contaminants from entering the original paint component container through the pour spout and prevents undesired leakage of the paint component out of the pour spout and past the cover element.
- Patent Number 6,053,218 issued April 25, 2000 both of which were filed on November 10, 1998, assigned to the same assignee as herein, and incorporated herein by reference thereto.
- this patent application is a Continuation-In-Part of U.S. Patent Application Serial Number 09/417,933 , entitled “Semi-Automated Automotive Paint Dispensing System;” of U.S. Patent Application Serial Number 09/416,729 , entitled “Lid Member For A Paint Container Useable With A Semi-Automated Automotive Paint Dispensing System;” and of U.S. Patent Application Serial Number 09/416,728 , entitled “Universal Paint Container Lid Member", all of which were filed on October 13, 1999, assigned to the same assignee as herein, and incorporated herein by reference thereto.
- paint vendors provide auto body repair businesses, such as body shops and jobbers, with their paint formulas.
- these paint formulas are a composition (i.e., mixture) of paint components, such as colorants, tints, pearls, metallics, binders and/or balancers, that, once mixed, produce the desired color of paint to be applied to a repaired vehicle.
- the paint formulas of the paint vendors are formulated to match the colors that have been applied to vehicles by new car manufacturers over the years.
- these paint formulas include variants, to match the color fading of paint that can occur to a vehicle over years of service.
- palettes of paint formulas of the paint vendors also have custom colors (i.e., unconventional colors not typically used by vehicle manufacturers) that may be used to produce special finishes for custom or show cars.
- paint vendors provide body shops and jobbers with literally thousands of paint formulas for producing the vast spectrum of colors needed in the automotive body repair industry.
- paint vendors would provide the body shops and jobbers with microfiche containing their paint formulas.
- Today the paint formulas are stored in computer memory.
- a system operator such as an employee of the body shop or jobber, first obtains the color code from the vehicle.
- This color code is typically part of the vehicle's identification number.
- the code for a particular color is obtained from a catalog.
- This color code is then entered into the microprocessor of the computer, which accesses the computer memory, and displays, via a monitor, the paint vendor's paint formula which matches the identified vehicle color code.
- the paint formulas are displayed according to the weight of the different paint components for mixing specific quantities of the paint formula, and the order in which the displayed paint components are to be mixed.
- paint formula mixing quantities are listed in quart, half gallon and gallon sizes, while the weight of the particular paint components needed to mix the desired quantity of paint, are listed in grams to a precision of a tenth of a gram.
- the paint components comprising tints, colorants, pearls and/or metallics are mixed first, while the paint components comprising binders and/or balancers are added last.
- the paint formula can require just a few paint components, or over a dozen paint components, that must be mixed with a great degree of precision, to achieve a perfect color match.
- the operator places a paint receptacle on a weigh cell that is linked to the microprocessor of the computer.
- a receptacle larger than the quantity of paint formula to be mixed is used to accommodate any excess paint inadvertently mixed by the operator.
- the weigh cell is zeroed by the operator, to make ready for the process of adding paint components to the receptacle to mix the desired color paint formula.
- the various paint components (of which there are dozens) are stored in containers kept within a rack.
- the rack has a mechanism that periodically stirs the paint components within the containers, so that the various paint components are ready to be dispensed as part of the paint formula mixing process.
- these containers are the original quart and gallon sized metal containers within which the paint components are shipped to the body shop or jobber. In metric system countries, these containers are the original one liter and four liter sized metal containers within which the paint components are shipped to the body shop or jobber.
- the original covers of these containers are replaced by specialized paint container lids that include stirring paddles that work with the stirring mechanism of the rack.
- These specialized paint container lids also have pour spouts that allow the paint components of the containers to be dispensed (i.e., poured out) into the receptacle atop the weigh cell.
- the pour spout of the specialized paint container lid is covered by a cover element that helps to protect the paint component within the container from contaminants.
- the cover element for the pour spout is movable between an opened state in which the paint component can be poured from its container through the pour spout by tipping (i.e., tilting) the container, and a closed state.
- the specialized paint container lid typically includes a vent to allow air to enter the container to displace the liquid paint component dispensed from the pour spout.
- United States Patent No. 4,750,648 discloses a lid with a manually-operable "guillotine"-type pouring arrangement which is especially adapted for mounting on paint containers intended for car bodywork and which are employed in stirring machines.
- the lid has at least one latching member for fastening it to an open paint container, a pouring spout with a flat-surfaced opening portion, a sliding element conforming with the opening portion of the pouring spout and being slidable on its flat surface, and a flat spring for urging the sliding element into contact with the pouring spout.
- the system operator begins by identifying the first listed paint component of the paint formula to be mixed. The operator then pours, by hand, the paint component into the weigh cell supported paint receptacle, until the weight of the paint component dispensed (i.e., poured) into the receptacle matches what is displayed on the computer monitor. The operator continues along on this course (i.e., hand pouring the paint components from their containers), until the correct weight of all paint components, needed to mix the desired color paint formula, have been added to the paint receptacle atop the weigh cell.
- over pouring errors are also costly in the amount of additional paint formula that is mixed because of the errors.
- Automotive paint can cost in excess of $ 100. 00 per quart.
- An over pouring error of just one pint may translate into an additional cost of $50.00 that a body shop or jobber may have to absorb, unless this additional paint cost can be justified to an automobile collision insurance carrier.
- this additional paint if not used in the rcpair/paint job, becomes a hazardous waste that must be disposed of properly, thereby adding still more costs that are attributable to paint component over pouring errors.
- paint container lid members that can be used with the original containers of the paint components, and are compatible with a system for dispensing paint components according to a paint formula that substantially eliminates system operator errors, specifically over pouring errors, that can be costly to a body shop or jobber.
- the paint container lid members together with the paint component dispensing system should be easy to use, so as not to require a highly skilled operator, and should make better use of an operator's time to allow an operator to mix a greater number of paint formulas during a work day.
- the paint container lid members should prevent contaminants from entering the original paint component container through the pour spout/cover element interface and prevent undesired leakage of the paint component out of the pour spout and past the cover element in the closed state of the cover element.
- the paint component lid members and the paint component dispensing system should comply with all regulations and laws governing the handling and mixing of paint components for the duplication of automotive paint formulas.
- the present invention is a lid member for an original container of a pourable component, as defined according to claim 1.
- Preferred embodiments of the invention are defined in the dependent claims.
- the lid member of the present invention can be used with the original container of a liquid paint component, and the seal mechanism prevents contaminants from entering the original paint component container through the pour spout/cover element interface.
- the seal mechanism of this lid member prevents undesired leakage of the paint component out of the pour spout and past the cover element in the closed state of the cover element.
- the guide mechanism also helps to prevent undesired leakage of the paint component out of the pour spout, by ensuring that the cover element is accurately aligned with the pour spout and guided during movement of the cover element between the closed and opened states.
- the securing mechanism ensures that the seal mechanism is properly and securely mounted to the cover element so as to be unaffected by the attributes of the paint component.
- the lid member of the present invention is compatible with a semi-automated system for dispensing liquid paint components from their original containers that virtually eliminates system operator errors, in particular over pouring errors, that can be costly to a body shop or jobber.
- the lid member and the semi-automated dispensing system are easy to use, and do not require a highly skilled operator, since operator interface with the lid members and the dispensing system is substantially limited to identifying the desired paint formula, and loading and unloading the proper containers of the liquid paint components to and from the dispensing apparatus.
- the dispensing system automatically dispenses (i.e., pours) the liquid paint components from their containers, thereby ensuring a highly accurate, precision liquid paint component pour.
- the lid member of the present invention together with the paint dispensing system makes efficient use of the operator's time, since the operator is free to perform other duties instead of manually pouring the proper amounts of the liquid paint components from their containers. This efficiency gain allows the operator to mix a greater number of paint formulas during a work day.
- the paint component lid member of the present invention together with the semi-automated dispensing system complies with all regulations and laws (such as being explosion protected) governing the safe handling and mixing of liquid paint components for the duplication of automotive paint formulas.
- FIGS. 1 and 2 A semi-automated dispensing system 10 for dispensing liquid paint components according to a paint formula to form a liquid paint mixture in accordance with the present invention is illustrated generally in FIGS. 1 and 2.
- the dispensing system 10 generally comprises a dispensing apparatus 12 for dispensing a liquid paint component 14 from its original container 16A and 16B, and a control apparatus 18 for controlling the dispensing apparatus 12.
- FIGS. 1, 3-8 show the quart size original container 16A having a lid member 20A
- FIG. 11 illustrates the gallon size original container 16B having a lid member 20B.

- liquid paint components 14 such as tints, colorants, pearls, metallics, binders and balancers (used to mix automotive paint according to a paint formula) are shipped from a liquid paint component manufacturer to customers, such as body shops and jobbers.
- the quart size and gallon size containers 16A and 16B are substantially identical. Therefore, only the quart size original container will be described with particularity.
- the lid members 20A and 20B are substantially similar, therefore the quart size lid member 20A will be described with particularity, and only the differences in the gallon size lid member 20B relative to the quart size lid member 20A will be described with particularity.

- Each of the cam lock mechanisms 28A is defined by a cam element 30A connected to a cam actuator 32A by way of a post member 34A. Pivotally moving the cam actuators 32A by hand, as represented by double headed arrow 36 (see FIG. 4), moves the cam elements 30A into and out of engagement with the lip 24A to secure and release the lid member 20A from the original container 16A.
- the lid member 20A further includes a handle 38A, for easy handling of the original container 16A when the lid member 20A is secured thereto.
- the handle 38A includes a first portion 39A generally parallel to the lip 24A of the original container 16A, a second portion 41 A (grasped by a user) that extends substantially perpendicular to the first portion 39, and a pair of oppositely directed dispensing system latch lugs 43A positioned at the intersection the first and second portions 39A, 41 A.
- the purpose of the pair of dispensing system latch lugs 43A will become clear below.
- the gallon size lid member 20B as illustrated in FIG.
- the pair of oppositely directed dispensing system latch lugs 43B are positioned along the length of the first portion 39B of the handle 38B instead of at the intersection of the first and second portions 39A and 41A as in the quart size lid member 20A.
- this different positioning of the dispensing system latch lugs 43A, 43B constitutes the main and only real difference between the lid members 20A and 20B.
- the lid member 20A also includes a liquid paint component pour spout 40A having a rear wall 81A, first and second opposed side walls 83A and 85A, respectively, and a front pour wall 87A. Also as seen in FIG. 5, immediately adjacent to (i.e., to the rear of) the rear wall 81 of the pour spout 40A, the lid member 20A includes first and second spaced guide surfaces 89A and 91A, respectively, the purpose of which will be made clear below.

- the cover element 44A When the thumb actuator 46A is positioned as shown in FIG. 3B, the cover element 44A is in its opened state. The cover element 44A is moved, from its closed state to its opened state, through the connecting wire loop 50A by pivoting the thumb actuator 46A about the pivot pin 48A against the bias of the spring element 54A. The cover element 44A is allowed to return to its closed state from the opened state by simply releasing the thumb actuator 46A.
- the lid member 20A also includes a rotatable roller element 51A (see FIGS. 4 and 5) that bears against the wire loop 50A to help maintain a seal between the cover element 44A and the pour spout 40A.

- the resilient seal member 450 provides an excellent fluid seal that prevents contaminants from entering the original container 16A through the pour spout 40A, and prevents leakage, upon tilting of the original container 16A, of the liquid paint component 14 out of the pour spout 40A past the cover element 44A in the closed state of the cover element 44A.
- the securing mechanism 460 is entirely mechanical in nature, the securing mechanism 460 is unaffected by attributes of paint components 14. Unlike some adhesives which may lose some of their adhesion qualities as a result of prolonged exposure to paint components 14, the securing mechanism 460 is capable of properly securing the resilient seal member 450 to the cover element 44A despite prolonged exposure to paint components 14.
- the resilient seal member 450 includes a guide mechanism 470 positioned between the pour spout 40A of the lid member 20A and the movable cover element 44A for guiding and aligning the cover element 44A on the pour spout 40A as the cover element 44A is moved between the closed and opened states.
- the guide mechanism 470 is defined by the cup shaped protruding portions 466. The protruding portions 466 slidably engage the first and second opposed side walls 83A and 85A (FIG. 14E) of the pour spout 40A and the first and second spaced guide surfaces 89A and 91A (FIG.

- the thumb actuator 46A is coupled to the plug element 63A by way of a wire loop element 67A that engages a groove 69A in the plug element 63A. Movement of the thumb actuator 46A between the positions shown in FIGS. 3A and 3B moves the plug element 63A (by way of the wire loop element 67A) between the sealed and unsealed positions. In the sealed position of the plug element 63A, contaminants are prevented from entering the vent passage 55A.
- the second open end 59A of the vent passage 55A is located radially exterior to the cylindrical side wall 71A of the original container 16A. This location of the second open end 59A of the vent passage 55A prevents the liquid paint component 14 from flowing out of the original container 16A through the vent passage 55A and the subsequent fouling of the exterior portions of the lid member 20A. This undesirable condition is prevented because the second open end 59A of the vent passage 55A is located above the fluid level of the liquid paint component 14 in the dispensing state of the liquid paint component illustrated in FIGS. 8 and 11.

- the force applying plate member 155 includes apertures 157 that freely receive the legs 151 of the U-shaped wire member 149 to permit movement of the plate member 155 along the legs 151.
- a compression spring 159 surrounds each of the legs 151 and acts between the operating device 141 and the plate member 155 to provide a biasing force urges the plate member 155 against the cover element 44A to prevent inadvertent leakage of the liquid paint component 14 from the pour spout 40A of the lid member 20 atop the original container 16A when the original container 16A is mounted in the dispensing system 10 (see FIG. 7) and the cover element 44A is in a closed position.
- a transit mechanism 150 of the dispensing mechanism 140 can pivotally move the operating device 141 between a first position and a second position.
- the cover element 44A of the lid member 20A In the first position of the operating device 141 (FIG. 7), the cover element 44A of the lid member 20A is in its closed state which prevents the liquid paint component 14 from being dispensed from the original container 16A with the help of the force applying mechanism 147.
- the cover element 44A In the second position of the operating device 141 (FIG. 8), the cover element 44A is in its opened state which allows the liquid paint component 14 to be dispensed (i.e., poured) from the original container 16A into a paint receptacle 152 (FIG. 1).
- the handles 38A and 38B of each of the lid members 20A and 20B include the latch lugs 43A, 43B.
- the difference in positioning of these latch lugs 43A and 43B between the quart size lid member 20A and the gallon size lid member 20B results in the latch lugs 43A, 43B being the same position relative to the alignment slot 56A, 56B.

Further, this patent application is a Continuation-In-Part ofU.S. Patent Application Serial Number 09/417,933 , entitled "Semi-Automated Automotive Paint Dispensing System;" ofU.S. Patent Application Serial Number 09/416,729 , entitled "Lid Member For A Paint Container Useable With A Semi-Automated Automotive Paint Dispensing System;" and ofU.S. Patent Application Serial Number 09/416,728 - In the automotive body repair industry, paint vendors provide auto body repair businesses, such as body shops and jobbers, with their paint formulas. Generally, these paint formulas are a composition (i.e., mixture) of paint components, such as colorants, tints, pearls, metallics, binders and/or balancers, that, once mixed, produce the desired color of paint to be applied to a repaired vehicle. The paint formulas of the paint vendors are formulated to match the colors that have been applied to vehicles by new car manufacturers over the years. In addition, these paint formulas include variants, to match the color fading of paint that can occur to a vehicle over years of service. Moreover, the palettes of paint formulas of the paint vendors also have custom colors (i.e., unconventional colors not typically used by vehicle manufacturers) that may be used to produce special finishes for custom or show cars. Hence, paint vendors provide body shops and jobbers with literally thousands of paint formulas for producing the vast spectrum of colors needed in the automotive body repair industry.
- In the past, paint vendors would provide the body shops and jobbers with microfiche containing their paint formulas. Today the paint formulas are stored in computer memory. To determine the particular paint formula for a particular vehicle repair/paint job, a system operator, such as an employee of the body shop or jobber, first obtains the color code from the vehicle. This color code is typically part of the vehicle's identification number. In the case of an unconventional color, to be used to produce a custom paint finish, the code for a particular color is obtained from a catalog. This color code is then entered into the microprocessor of the computer, which accesses the computer memory, and displays, via a monitor, the paint vendor's paint formula which matches the identified vehicle color code.
- The paint formulas are displayed according to the weight of the different paint components for mixing specific quantities of the paint formula, and the order in which the displayed paint components are to be mixed. Typically, paint formula mixing quantities are listed in quart, half gallon and gallon sizes, while the weight of the particular paint components needed to mix the desired quantity of paint, are listed in grams to a precision of a tenth of a gram. Generally, the paint components comprising tints, colorants, pearls and/or metallics are mixed first, while the paint components comprising binders and/or balancers are added last. Depending on the desired color, the paint formula can require just a few paint components, or over a dozen paint components, that must be mixed with a great degree of precision, to achieve a perfect color match.
- Once the system operator determines that the correct desired paint formula is displayed on the computer monitor, the operator places a paint receptacle on a weigh cell that is linked to the microprocessor of the computer. Generally, a receptacle larger than the quantity of paint formula to be mixed is used to accommodate any excess paint inadvertently mixed by the operator. With the receptacle on the weigh cell, the weigh cell is zeroed by the operator, to make ready for the process of adding paint components to the receptacle to mix the desired color paint formula. Generally, the various paint components (of which there are dozens) are stored in containers kept within a rack. The rack has a mechanism that periodically stirs the paint components within the containers, so that the various paint components are ready to be dispensed as part of the paint formula mixing process. Typically, these containers are the original quart and gallon sized metal containers within which the paint components are shipped to the body shop or jobber. In metric system countries, these containers are the original one liter and four liter sized metal containers within which the paint components are shipped to the body shop or jobber. The original covers of these containers are replaced by specialized paint container lids that include stirring paddles that work with the stirring mechanism of the rack. These specialized paint container lids also have pour spouts that allow the paint components of the containers to be dispensed (i.e., poured out) into the receptacle atop the weigh cell. The pour spout of the specialized paint container lid is covered by a cover element that helps to protect the paint component within the container from contaminants. The cover element for the pour spout is movable between an opened state in which the paint component can be poured from its container through the pour spout by tipping (i.e., tilting) the container, and a closed state. The specialized paint container lid typically includes a vent to allow air to enter the container to displace the liquid paint component dispensed from the pour spout.

United States Patent No. 4,750,648 discloses a lid with a manually-operable "guillotine"-type pouring arrangement which is especially adapted for mounting on paint containers intended for car bodywork and which are employed in stirring machines. The lid has at least one latching member for fastening it to an open paint container, a pouring spout with a flat-surfaced opening portion, a sliding element conforming with the opening portion of the pouring spout and being slidable on its flat surface, and a flat spring for urging the sliding element into contact with the pouring spout. - To reproduce the desired paint formula, the system operator begins by identifying the first listed paint component of the paint formula to be mixed. The operator then pours, by hand, the paint component into the weigh cell supported paint receptacle, until the weight of the paint component dispensed (i.e., poured) into the receptacle matches what is displayed on the computer monitor. The operator continues along on this course (i.e., hand pouring the paint components from their containers), until the correct weight of all paint components, needed to mix the desired color paint formula, have been added to the paint receptacle atop the weigh cell.
- Although the above described system for mixing paint components (according to a paint formula), using the original containers of the liquid paint components and the above described specialized container lids, allows a skilled system operator to dispense the needed paint components to adequately recreate paint colors needed for repair/paint jobs, there are some disadvantages to this system. For example, during the process of dispensing the liquid paint component from the specialized container lid, the liquid paint component often undesirably flows out of the pour spout past the cover element when the cover element is in the closed position. In addition contaminants can enter the original container through the cover element/pour spout interface thereby adversely affecting the quality of the paint component contained within the original container. Moreover, to mix a desired paint formula requires that the paint components be added to the paint receptacle, atop the weigh cell, with a great degree of accuracy. This accuracy, as stated earlier, is typically to a precision of 0.1 grams. For even a highly skilled operator this great degree of precision is difficult to obtain when hand pouring the paint components needed to mix the desired paint formula. It is especially difficult when many paint components must be poured into the paint receptacle in order to duplicate the paint formula.
- The most common error on the part of the system operator of the body shop or jobber is over pouring which is due primarily to the manual labor intensive nature of the paint component dispensing process. Over pouring occurs when the weight of the paint component added to the receptacle atop the weigh cell, exceeds the weight of the component shown on the computer display for the desired paint formula. When this happens, the microprocessor of the computer recalculates the weights of the other paint components that need to be added to the receptacle to compensate for the over poured component. This recalculation is done automatically by the microprocessor since the weigh cell is linked to the computer. Based upon this recalculation, the system operator then needs to re-pour the other paint components to offset the over poured component of the paint formula.
- While this re-pouring task may not be difficult when the paint formula only has a few paint components, the re-pouring task is particularly time consuming when there is a great number of components in the paint formula. Specifically, if an over pouring error is made in the last paint component of a series of ten components of a paint formula, then all of the previous nine components may have to be re-poured to compensate. This re-pouring task may be further complicated if another error is made during the re-pouring of the paint components, as this further error may require that some components be re-poured two or three times until the paint formula is finally accurately reproduced. Hence, over pouring errors can be costly to a body shop or jobber because of the additional man hours needed to mix the paint formula.
- Not only are over pouring errors expensive because of the additional man hours needed to reproduce the paint formula, over pouring errors are also costly in the amount of additional paint formula that is mixed because of the errors. Automotive paint can cost in excess of $ 100. 00 per quart. An over pouring error of just one pint may translate into an additional cost of $50.00 that a body shop or jobber may have to absorb, unless this additional paint cost can be justified to an automobile collision insurance carrier. Moreover, this additional paint, if not used in the rcpair/paint job, becomes a hazardous waste that must be disposed of properly, thereby adding still more costs that are attributable to paint component over pouring errors.
- There is a need for an improved system for mixing paint components according to a paint formula. In particular, there is a need for paint container lid members that can be used with the original containers of the paint components, and are compatible with a system for dispensing paint components according to a paint formula that substantially eliminates system operator errors, specifically over pouring errors, that can be costly to a body shop or jobber. The paint container lid members together with the paint component dispensing system should be easy to use, so as not to require a highly skilled operator, and should make better use of an operator's time to allow an operator to mix a greater number of paint formulas during a work day. Moreover, the paint container lid members should prevent contaminants from entering the original paint component container through the pour spout/cover element interface and prevent undesired leakage of the paint component out of the pour spout and past the cover element in the closed state of the cover element. In addition, the paint component lid members and the paint component dispensing system should comply with all regulations and laws governing the handling and mixing of paint components for the duplication of automotive paint formulas.
- The present invention is a lid member for an original container of a pourable component, as defined according to
claim 1. Preferred embodiments of the invention are defined in the dependent claims. - The lid member of the present invention can be used with the original container of a liquid paint component, and the seal mechanism prevents contaminants from entering the original paint component container through the pour spout/cover element interface. In addition, the seal mechanism of this lid member prevents undesired leakage of the paint component out of the pour spout and past the cover element in the closed state of the cover element. The guide mechanism also helps to prevent undesired leakage of the paint component out of the pour spout, by ensuring that the cover element is accurately aligned with the pour spout and guided during movement of the cover element between the closed and opened states. The securing mechanism ensures that the seal mechanism is properly and securely mounted to the cover element so as to be unaffected by the attributes of the paint component.
- The lid member of the present invention is compatible with a semi-automated system for dispensing liquid paint components from their original containers that virtually eliminates system operator errors, in particular over pouring errors, that can be costly to a body shop or jobber. The lid member and the semi-automated dispensing system are easy to use, and do not require a highly skilled operator, since operator interface with the lid members and the dispensing system is substantially limited to identifying the desired paint formula, and loading and unloading the proper containers of the liquid paint components to and from the dispensing apparatus. The dispensing system automatically dispenses (i.e., pours) the liquid paint components from their containers, thereby ensuring a highly accurate, precision liquid paint component pour. This highly accurate liquid paint component pour substantially limits the additional cost of the added paint components attributable to over pouring errors. In addition, the lid member of the present invention together with the paint dispensing system makes efficient use of the operator's time, since the operator is free to perform other duties instead of manually pouring the proper amounts of the liquid paint components from their containers. This efficiency gain allows the operator to mix a greater number of paint formulas during a work day. Lastly, the paint component lid member of the present invention, together with the semi-automated dispensing system complies with all regulations and laws (such as being explosion protected) governing the safe handling and mixing of liquid paint components for the duplication of automotive paint formulas.

- A
semi-automated dispensing system 10 for dispensing liquid paint components according to a paint formula to form a liquid paint mixture in accordance with the present invention is illustrated generally in FIGS. 1 and 2. The dispensingsystem 10 generally comprises a dispensingapparatus 12 for dispensing aliquid paint component 14 from itsoriginal container control apparatus 18 for controlling the dispensingapparatus 12. FIGS. 1, 3-8 show the quart sizeoriginal container 16A having alid member 20A, while FIG. 11 illustrates the gallon sizeoriginal container 16B having alid member 20B. In metric system countries, thelid member 20A fits a one liter size original container and thelid member 20B fits a four liter size original container. Thecontainers lid members liquid paint components 14, such as tints, colorants, pearls, metallics, binders and balancers (used to mix automotive paint according to a paint formula) are shipped from a liquid paint component manufacturer to customers, such as body shops and jobbers. Beyond their size differences, the quart size andgallon size containers lid members size lid member 20A will be described with particularity, and only the differences in the gallonsize lid member 20B relative to the quartsize lid member 20A will be described with particularity. - As seen best in FIGS. 3A and 3B, the
original container 16A is cylindrical shaped having an open top 22A defined by acircumferential lip 24A. As seen best in FIGS. 3-5, thelid member 20A includes abase portion 26A adapted to engage and seal the open top 22A of thecontainer 16A to protect theliquid paint component 14 within thecontainer 16A. Thebase portion 26A of thelid member 20A includes a pair of spaced, pivotablecam lock mechanisms 28A that are used to releasably secure thelid member 20A to theoriginal container 16A. Each of thecam lock mechanisms 28A is defined by acam element 30A connected to acam actuator 32A by way of apost member 34A. Pivotally moving thecam actuators 32A by hand, as represented by double headed arrow 36 (see FIG. 4), moves thecam elements 30A into and out of engagement with thelip 24A to secure and release thelid member 20A from theoriginal container 16A. - The
lid member 20A further includes ahandle 38A, for easy handling of theoriginal container 16A when thelid member 20A is secured thereto. Thehandle 38A includes afirst portion 39A generally parallel to thelip 24A of theoriginal container 16A, asecond portion 41 A (grasped by a user) that extends substantially perpendicular to the first portion 39, and a pair of oppositely directed dispensing system latch lugs 43A positioned at the intersection the first andsecond portions size lid member 20B, as illustrated in FIG. 11, the pair of oppositely directed dispensing system latch lugs 43B are positioned along the length of thefirst portion 39B of thehandle 38B instead of at the intersection of the first andsecond portions size lid member 20A. Other than the size differences between the quartsize lid member 20A and the gallonsize lid member 20B, this different positioning of the dispensing system latch lugs 43A, 43B constitutes the main and only real difference between thelid members - As seen best in FIG. 5, the
lid member 20A also includes a liquid paint component pourspout 40A having arear wall 81A, first and secondopposed side walls wall 87A. Also as seen in FIG. 5, immediately adjacent to (i.e., to the rear of) the rear wall 81 of the pourspout 40A, thelid member 20A includes first and second spacedguide surfaces spout 40A is covered by a linearly movable, as represented by double headed directional arrow 42 (see FIGS. 3A and 3B),cover element 44A. Thecover element 44A is linearly movable between a closed state (shown in FIG. 3A) and an opened state (shown in FIG. 3B). In the closed state of thecover element 44A, theliquid paint component 14 is prevented from being poured (i.e., dispensed) from theoriginal container 16A through the pourspout 40A. In the opened state of thecover element 44A, theliquid paint component 14 can be poured from theoriginal container 16A through the pourspout 40A by tilting thecontainer 16A using thehandle 38A. - As seen when comparing FIGS. 3A and 3B, the
cover element 44A is movable between its closed and opened states via athumb actuator 46A that is pivotally secured to thebase portion 26A by way of apivot pin 48A. Thethumb actuator 46A is pivotally movable as shown by double headeddirectional arrow 47. As seen best in FIG. 4, thethumb actuator 46A is connected to thecover element 44A via awire loop 50A. When thethumb actuator 46A is positioned as shown in FIG. 3A, thecover element 44A is in its closed state. Thethumb actuator 46A is biased to this normal position in a known manner by acoil spring element 54A (see FIGS. 3A and 3B). Thecoil spring element 54A acts between thebase portion 26A and thethumb actuator 46A. When thethumb actuator 46A is positioned as shown in FIG. 3B, thecover element 44A is in its opened state. Thecover element 44A is moved, from its closed state to its opened state, through the connectingwire loop 50A by pivoting thethumb actuator 46A about thepivot pin 48A against the bias of thespring element 54A. Thecover element 44A is allowed to return to its closed state from the opened state by simply releasing thethumb actuator 46A. Thelid member 20A also includes arotatable roller element 51A (see FIGS. 4 and 5) that bears against thewire loop 50A to help maintain a seal between thecover element 44A and the pourspout 40A. As seen in FIGS. 3-5, thecover element 44A also includes aslot 49A the purpose of which will be made clear below. - As seen best in FIGS. 5 and 14A-G, the
walls spout 40A define a circumferential,planar edge surface 350A, and thecover element 44A includes a planarlower surface 352A. Aresilient seal mechanism 354 is positioned at anengagement interface 356 between the circumferential,planar edge surface 350A of the pourspout 40A and the planarlower surface 352A of thecover element 44A. Theresilient seal mechanism 354 prevents leakage, upon tilting of theoriginal container 16A, of theliquid paint component 14 out of the pourspout 40A past thecover element 44A in the closed state of thecover element 44A. - As illustrated in FIG. 14A, in a background example, the
resilient seal mechanism 354 is defined by aresilient seal member 357 that covers the entire planarlower surface 352A of thecover element 44A. Theresilient seal member 357 comprises afirst substrate 358 of a resilient material, such as foam, and asecond substrate 360 of a smooth material, such as polyethylene. Alternatively, thesecond substrate 360 could comprise TEFLON. In a variant, thefirst substrate 358 has a thickness of approximately 7.62 µm (0.0003 inches) and thesecond substrate 360 has a thickness of 2.54 µm (0.0001 inches). Theresilient seal member 357 is secured, via thefirst substrate 358, to the planarlower surface 352A of thecover element 44A via a suitable adhesive. Thesecond substrate 360 engages the circumferential,planar edge surface 350A of the pourspout 40A. The smoothness of thesecond substrate 360 allows thecover element 44A to readily move relative to the pour spout between the open and closed states. As seen in FIG. 14A, the resiliency of thefirst substrate 358 allows theresilient seal member 357 to conform to the shape of the circumferential,planar edge surface 350A of the pourspout 40A. By conforming to the shape of the pourspout 40A, theresilient seal member 357 provides an excellent fluid seal that prevents contaminants from entering theoriginal container 16A through the pourspout 40A, and prevents leakage, upon tilting of theoriginal container 16A, of theliquid paint component 14 out of the pourspout 40A past thecover element 44A in the closed state of thecover element 44A. - FIG. 14B illustrates an alternative background example of a
resilient seal member 370. Theresilient seal member 370 is defined by a rubber O-ring 372 that is mounted within acircumferentially extending channel 374 in the circumferential,planar edge surface 350A of the pourspout 40A. The resiliency of the rubber O-ring 372 allows theresilient seal member 370 to conform to the shape of the planarlower surface 352A of thecover element 44A. By conforming to the shape of thecover element 44A, theresilient seal member 356 provides an excellent fluid seal that prevents contaminants from entering theoriginal container 16A through the pourspout 40A, and prevents leakage, upon tilting of theoriginal container 16A, of theliquid paint component 14 out of the pourspout 40A past thecover element 44A in the closed state of thecover element 44A. - FIG. 14C illustrates another alternative background example of a
resilient seal member 380. Theresilient seal member 380 is defined by a generally U-shaped,rubber seal element 382 having anengagement channel 384 for receiving the circumferential,planar edge surface 350A of the pourspout 40A for mounting theresilient seal member 380 to the pourspout 40A. Anupper surface 385 of theseal element 382 includes acircumferential ridge 386 that engages the planarlower surface 352A of thecover element 44A. The resiliency of theridge 386 allows theresilient seal element 382 to conform to the shape of the planarlower surface 352A of thecover element 44A. By conforming to the shape of thecover element 44A, theresilient seal element 382 provides an excellent fluid seal that prevents contaminants from entering theoriginal container 16A through the pourspout 40A, and prevents leakage, upon tilting of theoriginal container 16A, of theliquid paint component 14 out of the pourspout 40A past thecover element 44A in the closed state of thecover element 44A. - FIG. 14D illustrates a further alternative background example of a
resilient seal member 390. Theresilient seal member 390 is defined by a generally U-shaped,rubber seal element 392 having anengagement channel 394 for receiving the circumferential,planar edge surface 350A of the pourspout 40A for mounting theresilient seal member 390 to the pourspout 40A. Anupper surface 395 of theseal element 392 includes acircumferential extension 396 that is directed exterior to the pourspout 40A and engages the planarlower surface 352A of thecover element 44A. The dashed line representation of theextension 396 is the normal inoperative state of theextension 396. The solid line representation of theextension 396 is the flexed operative state of theextension 396. The resiliency of theextension 396 allows theresilient seal element 392 to conform to the shape of the planarlower surface 352A of thecover element 44A. By conforming to the shape of thecover element 44A, theresilient seal element 392 provides an excellent fluid seal that prevents contaminants from entering theoriginal container 16A through the pourspout 40A, and prevents leakage, upon tilting of theoriginal container 16A, of theliquid paint component 14 out of the pourspout 40A past thecover element 44A in the closed state of thecover element 44A. - As illustrated in FIGS. 14E-14G, in a preferred embodiment, the
resilient seal mechanism 354 is defined by aresilient seal member 450 that covers the entire planarlower surface 352A of thecover element 44A. Theresilient seal member 450 comprises afirst substrate 452 of a resilient material, and asecond substrate 454 of a flexible and smooth material. In one preferred embodiment, the resilient material of thefirst substrate 452 is high density polyethylene closed cell foam, and the flexible and smooth material of thesecond substrate 454 is ultra high molecular weight polyethylene plastic sheet. Alternatively, thesecond substrate 454 could comprise TEFLON. In one preferred embodiment, thefirst substrate 452 has a thickness of approximately 12.7 µm (0.00050 inches) and thesecond substrate 454 has a thickness of 5.08 µm (0.00020 inches). - The
resilient seal member 450 is secured, via asecuring mechanism 460, to the planarlower surface 352A of thecover element 44A. As seen in FIGS. 14E-14G, 15 and 16, thesecuring mechanism 460 includes a plurality of spacedprotrusions 462 that are integrally formed with thecover element 44A and extend from the planarlower surface 352A thereof In one preferred embodiment, there are four spacedprotrusions 462. The spacedprotrusions 462 engage the first andsecond substrates resilient seal member 450 to secure thesubstrates 452, 454 (i.e., the resilient seal member 450) to thecover element 44A. To accomplish this securing function, thefirst substrate 452 includes a plurality of spacedopenings 464. In one preferred embodiment, there are four spacedopenings 464 that are formed via die cutting. Each of theopenings 464 is sized to closely receive one of theprotrusions 462 to secure thefirst substrate 452 against the planarlower surface 352A of thecover element 44A. Theprotrusions 462 cooperate with the closelyfitting openings 464 to hold thefirst substrate 452 to thecover element 44A via only frictional engagement. - To further accomplish the securing function of the
securing mechanism 460, thesecond substrate 454 includes a plurality of cup shaped protrudingportions 466. In one preferred embodiment, there are four cup shaped protrudingportions 466 that are formed in thesecond substrate 454 during the injection molding process used to form thesecond substrate 454. Each of the protrudingportions 466 is sized to closely receive one of theprotrusions 462 to secure thesecond substrate 454 against thefirst substrate 452 and to the planarlower surface 352A of thecover element 44A. Theprotrusions 462 cooperate with the closely fitting cup shaped protrudingportions 466 to hold thesecond substrate 454 to thecover element 44A via only frictional engagement. Thesecond substrate 452 includes an upstandingperipheral wall 468 that acts to enclose thefirst substrate 452. - The
first substrate 452 engages the planarlower surface 352A of thecover element 44A, and thesecond substrate 454 engages the circumferential,planar edge surface 350A of the pourspout 40A. The smoothness of thesecond substrate 454 allows thecover element 44A to readily move relative to the pourspout 40A between the open and closed states. As seen in FIG. 14E, the resiliency of thefirst substrate 452 combined with the flexibility of thesecond substrate 454 allows theresilient seal member 450 to conform to the shape of the circumferential,planar edge surface 350A of the pourspout 40A. In addition, as can be seen when comparing FIGS. 14G and 16, the cup shaped protrudingportions 466 slidably receive theprotrusions 462 so as to allow some movement of thesecond substrate 454 relative to thecover element 44A upon compression and extension of thefirst substrate 452. This movement of thesecond substrate 454 relative to thecover element 44A is substantially perpendicular to the planarlower surface 352A of thecover element 44A and allows theresilient seal member 450 to engage and conform to the shape of the circumferential,planar edge surface 350A of the pourspout 40A. FIG. 16 illustrates thefirst substrate 452 in an uncompressed state with a first length L1 existing between the bottom of theprotrusions 462 and the bottom of the cup shaped protrudingportions 466. FIG. 14G illustrates thefirst substrate 452 in a compressed state with a second length L2 that is less than the first length L1 existing between the bottom of theprotrusions 462 and the bottom of the cup shaped protrudingportions 466. By conforming to the shape of the pourspout 40A, theresilient seal member 450 provides an excellent fluid seal that prevents contaminants from entering theoriginal container 16A through the pourspout 40A, and prevents leakage, upon tilting of theoriginal container 16A, of theliquid paint component 14 out of the pourspout 40A past thecover element 44A in the closed state of thecover element 44A. Since thesecuring mechanism 460 is entirely mechanical in nature, thesecuring mechanism 460 is unaffected by attributes ofpaint components 14. Unlike some adhesives which may lose some of their adhesion qualities as a result of prolonged exposure to paintcomponents 14, thesecuring mechanism 460 is capable of properly securing theresilient seal member 450 to thecover element 44A despite prolonged exposure to paintcomponents 14. - As seen in FIGS. 14E and 14F, the
resilient seal member 450 includes aguide mechanism 470 positioned between the pourspout 40A of thelid member 20A and themovable cover element 44A for guiding and aligning thecover element 44A on the pourspout 40A as thecover element 44A is moved between the closed and opened states. Theguide mechanism 470 is defined by the cup shaped protrudingportions 466. The protrudingportions 466 slidably engage the first and secondopposed side walls spout 40A and the first and second spacedguide surfaces lid member 20A for guiding and aligning thecover element 44A on the pourspout 40A during movement of thecover element 44A. As seen in FIGS. 14E and 14F, each of the protrudingportions 466 slidably engages only one of the first and second side walls or guidesurfaces - As seen in FIGS. 3-4, the
base portion 26A of thelid member 20A includes avent member 53A defining avent passage 55A that has a firstopen end 57A and an opposite secondopen end 59A. Thevent passage 55A passes through thebase portion 26A such that the firstopen end 57A communicates with aninterior region 61 A of theoriginal container 16A and the secondopen end 59A communicates with atmosphere. The secondopen end 59A is sealable by way of a linearlymovable plug element 63A. As seen best when comparing FIGS. 3A and 3B, theplug element 63A is linearly movable between a sealed position (see FIG. 3A) wherein a cone shapedend 65A of theplug element 63A is engaged with the secondopen end 59A of thevent passage 55A, and an unsealed position (see FIG. 3B) wherein the cone shapedend 65A of theplug element 63A is disengaged from the secondopen end 59A of thevent passage 55A. - The
plug element 63A is linearly movable between the sealed and unsealed positions by actuation of thethumb actuator 46A. Thethumb actuator 46A is coupled to theplug element 63A by way of awire loop element 67A that engages agroove 69A in theplug element 63A. Movement of thethumb actuator 46A between the positions shown in FIGS. 3A and 3B moves theplug element 63A (by way of thewire loop element 67A) between the sealed and unsealed positions. In the sealed position of theplug element 63A, contaminants are prevented from entering thevent passage 55A. In the unsealed position of theplug element 63A (which occurs when theliquid paint component 14 is being dispensed from theoriginal container 16A through the pourspout 40A upon actuation of thethumb actuator 46A), air is allowed to enter thevent passage 55A through the secondopen end 59A so that the air passes into theinterior region 61 A of theoriginal container 16A through the secondopen end 57A to fill the void of the dispensedliquid paint component 14. - As seen best in FIGS. 3-8, the second
open end 59A of thevent passage 55A is located radially exterior to thecylindrical side wall 71A of theoriginal container 16A. This location of the secondopen end 59A of thevent passage 55A prevents theliquid paint component 14 from flowing out of theoriginal container 16A through thevent passage 55A and the subsequent fouling of the exterior portions of thelid member 20A. This undesirable condition is prevented because the secondopen end 59A of thevent passage 55A is located above the fluid level of theliquid paint component 14 in the dispensing state of the liquid paint component illustrated in FIGS. 8 and 11. Thevent passage 55A extends substantially perpendicular to and radially from acentral axis 73 of theoriginal container 16A (see FIG. 3A). - As seen best in FIGS. 3 and 4, the
lid member 20A further includes analignment slot 56A positioned at a first portion of thelid member 20A at the pourspout 40A adjacent to thecover element 44A.

engaging mechanism 100 includes first and second spacedarms registration rod 108 rigidly connects together the first andsecond arms free ends registration rod 108 is adapted to releasably receive (i.e., engage) thealignment slot 56A of thelid member 20A. As seen in FIG. 6, interengagement of thealignment slot 56A with theregistration rod 108 mounts (i.e., secures) and aligns a first portion of thecontainer 16A andlid member 20A combination to thereceiving mechanism 98 of the dispensingapparatus 12. - The second
engaging mechanism 102 includes first and second spacedplates support frame 80. Free ends 113a and 113b of theplates latch slots 115a and 115b, respectively. The secondengaging mechanism 102 further includes first and second spaced L-shapedarms support frame 80 via apivot pin 116. Ahandle member 118 rigidly connects together the first and second L-shapedarms first ends arms notches notches handle 38A of thelid member 20A for theoriginal container 16A to secure the latch lugs 43A in thelatch slots 115a and 115b of theplates arms engaging mechanism 102 are pivotally movable as a unit, as represented by double headedarrow 125, between an unlatched state, wherein theoriginal container 16A of theliquid paint component 14 can be engaged with and disengaged from the first and secondengaging mechanisms 100 and 102 (shown in FIG. 6); and a latched state, wherein theoriginal container 16A is securely held between the first and secondengaging mechanisms 100 and 102 (shown in FIG. 7). As such the L-shapedarms support frame 80 and the first engaging mechanism 100 (i.e., the first and second spacedarms tension spring element 126 is coupled between a mountingpeg 128 of thesupport frame 80 and a mountingpeg 129 of anextension arm 130 on the L-shapedarm 114a. Thetension spring element 126 biases the L-shapedarms engaging mechanism 102 to the latched state against thestop 133. A handle/stop member 134 limits movement of the L-shapedarms - As seen best in FIGS. 2 and 6, the dispensing
apparatus 12 of the dispensingsystem 10 further includes dispensingmechanism 140 mounted to thesupport frame 80 for moving thecover element 44A of thelid member 20A between its closed and open states. Thedispensing mechanism 140 includes outwardly extending, first andsecond arms operating device 141 pivotally movable, as a unit, as represented by double headed directional arrow 143 (FIG. 8), relative to thesupport frame 80 about anaxle 145. The free ends 146a and 146b, of the first andsecond arms slot 49A in thecover element 44A on thelid member 20A (see FIGS. 6-10). Theforce applying mechanism 147 includesU-shaped wire member 149 havinglegs 151 and a connectingportion 153. Thelegs 151 are rigidly mounted to theoperating device 141. As seen best in FIGS. 9 and 10, the connectingportion 153 is releasably received within theslot 49A of thecover element 44A. Theforce applying mechanism 147 further includes a force applyingplate member 155 that is linearly movable relative to theU-shaped wire member 149 as represented by double headedarrow 330. The force applyingplate member 155 includesapertures 157 that freely receive thelegs 151 of theU-shaped wire member 149 to permit movement of theplate member 155 along thelegs 151. Acompression spring 159 surrounds each of thelegs 151 and acts between the operatingdevice 141 and theplate member 155 to provide a biasing force urges theplate member 155 against thecover element 44A to prevent inadvertent leakage of theliquid paint component 14 from the pourspout 40A of the lid member 20 atop theoriginal container 16A when theoriginal container 16A is mounted in the dispensing system 10 (see FIG. 7) and thecover element 44A is in a closed position. - As seen in FIG. 8, with the connecting
portion 153 of theforce applying mechanism 147 of theoperating device 141 engaged with theslot 49A of thecover element 44A, atransit mechanism 150 of thedispensing mechanism 140 can pivotally move theoperating device 141 between a first position and a second position. In the first position of the operating device 141 (FIG. 7), thecover element 44A of thelid member 20A is in its closed state which prevents theliquid paint component 14 from being dispensed from theoriginal container 16A with the help of theforce applying mechanism 147. In the second position of the operating device 141 (FIG. 8), thecover element 44A is in its opened state which allows theliquid paint component 14 to be dispensed (i.e., poured) from theoriginal container 16A into a paint receptacle 152 (FIG. 1). - As set forth previously, the
handles lid members size lid member 20A and the gallonsize lid member 20B results in the latch lugs 43A, 43B being the same position relative to thealignment slot engaging mechanisms 100 and 102) and thedispensing mechanism 140 to accommodate quart sizeoriginal containers 16A (FIGS. 6-8) and gallon sizeoriginal containers 16B (FIG. 11). - As seen best in FIGS. 6, the
transit mechanism 150 of thedispensing mechanism 140 includes apiston member 154 linearly movable, along directional arrow 143 (FIG. 6), relative to acylinder member 156. Opposite ends 253a and 253b of the first andsecond arms piston member 154. Apad member 158 of the piston member rides on aroller member 259 rotatably mounted to thearms piston member 154 within thecylinder member 156 causes theoperating device 141 to move between its first and second positions.Tension spring elements 160 are coupled between the opposite ends 253a, 253b of thearms member 162 on thesupport frame 80. The tension springs 160 bias theoperating device 141 to its first position (also known as the primary position of the piston member 154). - As seen in FIG. 1, a
drive mechanism 170 of thetransit mechanism 150 moves thepiston member 154 relative to thecylinder member 156. Thedrive mechanism 170 includes apiston member 172 linearly movable, along double headeddirectional arrow 173, relative to acylinder member 174 mounted to aframe 176 viabracket structure 177. A drive motor, such as astepper motor 178, is also mounted to theframe 176. Thedrive motor 178 includes adrive screw 179 that is telescopically received within adrive tube 180 that is secured at one end to thepiston member 172. Thedrive tube 180 is slidably received within a bearing 181 of theframe 176 to allow movement of thedrive tube 180, and thepiston member 172 therewith, relative to theframe 176, drivemotor 178 andcylinder member 174. An opposite end of thedrive tube 180 includes adrive nut 183 that threadably receives thedrive screw 179 of thestepper motor 178. Operation of thestepper motor 178 turns thedrive screw 179 within thedrive nut 183. This in turn moves thedrive tube 180 and therewith thepiston member 172 within thecylinder member 174 alongdirectional arrow 173. Afluid reservoir 182 containing ahydraulic fluid 184 is in fluid communication with thecylinder member 174. Afluid line 188 couples thefluid reservoir 182 to thecylinder member 156. In operation, movement of thepiston member 172, via thestepper motor 178, forceshydraulic fluid 184 to move to and from thecylinder member 174 and thefluid reservoir 182 through theline 188 then into and out of thecylinder member 156 to move thepiston member 154. Movement of thepiston member 154, via the above described hydraulic fluid pressure, in turn moves theoperating device 141 which in turn moves thecover element 44A of thelid member 20A between its opened and closed states. - As seen in FIGS. 12 and 13, the dispensing
system 10 includes anautomatic bleeder valve 300 to aid in initially filling the dispensingsystem 10 withhydraulic fluid 184. Thehydraulic bleeder valve 300 includes abody member 302 defining anorifice 304 that extends through thebody member 302 from afirst end 306 to asecond end 308. Theorifice 304 is in fluid communication with thefluid line 188 and thecylinder member 156. A linearlymovable ball valve 310 is positioned at thefirst end 306 of thebody member 302. Theball valve 310 is movable between a first position, wherein theball valve 310 forms a fluid seal and air/hydraulic fluid 184 is prevented from passing into the orifice 304 (see FIG. 12), and a second position wherein theball valve 310 acts as a check valve and air and/orhydraulic fluid 184 may pass through theorifice 304 from thefirst end 306 to the second end 308 (see FIG. 13). Thebody member 302 threadably engages thesupport frame 80 viathreads 307 so as to be movable linearly relative thereto. Thebody member 302 includes anut 314 at thesecond end 308 used to twist thebody member 302 to move thebody member 302 relative to thesupport frame 80. Near thefirst end 306, thebody member 302 includes an O-ring seal member 312 to prevent air/hydraulic fluid 184 from flowing past thebody member 302 through thethreads 307. Aninner end 316 of thebody member 302 bears against acompression spring 318 that in turn bears against theball valve 310. - In operation, to fill the
cylinder member 156 withhydraulic fluid 184, thebody member 302 is loosened using thenut 314 which decompresses thespring 318 and allows theball valve 310 to move to the position shown in FIG. 13.Hydraulic fluid 184 is then pumped through thefluid line 188 from thereservoir 182 via thepiston member 172 of thedrive mechanism 170. Thehydraulic fluid 184 passes from thefluid line 188 into thecylinder member 156 primarily due to gravity and because this is the fluid path of least resistance. Air within thefluid line 188 and thecylinder member 156 is automatically bled out (by the introduction of the hydraulic fluid 184) through theautomatic bleeder valve 300. The air passes around theball valve 310, through thespring 318 and through theorifice 304 as represented by thearrows 325 in FIG. 13. Thefluid line 188 andcylinder member 156 are full ofhydraulic fluid 184 when thehydraulic fluid 184 passes out of theorifice 304. Thebody member 302 is then tightened using thenut 314 which causes theinner end 316 of thebody member 302 to bear against thespring 318 which compresses the spring against theball valve 310 sealing off theorifice 304 of thebleeder valve 300, thereby completing the filling process (see FIG. 12). - As seen in FIG. 1, the
control apparatus 18 of the dispensingsystem 10 includes aweigh cell 190 for supporting thepaint receptacle 152 and acontrol module 192. Theweigh cell 190 determines the weight of the liquid paint component dispensed (i.e., poured) from theoriginal container 16A into thepaint receptacle 152. Thecontrol module 192 includes adisplay monitor device 194 having adisplay 195, amicroprocessor device 196, adata storage device 198 and a user interface device, such as akeyboard 200. Thekeyboard 200 is coupled to themicroprocessor device 196 via a communication line 202. Themicroprocessor device 196 and thedata storage device 198 are linked through acommunication line 204. Themicroprocessor device 196 is linked to thestepper motor 178 and to asensor 205 for monitoring the position of thedrive screw 179 through thecommunication line 206. Themicroprocessor device 196 is linked to thedisplay monitor device 194 throughcommunication line 208 and is further linked to theweigh cell 190 viacommunication line 210. Since the control module 192 (i.e., microprocessor device 196) is linked to thestepper motor 178 and thesensor 205, thecontrol module 192 can control operation of thestepper motor 178, and thereby movement of thepiston members cover element 44A to dispense theliquid paint component 14 from theoriginal container 16A. In addition, since thecontrol module 192 is further linked to theweigh cell 190, thecontrol module 192 can control the amount (i.e., the weight) of theliquid paint component 14 dispensed from itsoriginal container 16A to the paint receptacle 152 (atop the weigh cell 190) based upon data (i.e., information) obtained from theweigh cell 190. Moreover, since the control module 192 (i.e., the data storage device 198) stores the paint formulas, thecontrol module 192 can determine whichliquid paint components 14 and the weights of these components needed to duplicate a particular paint formula and can control thedispensing mechanism 140 in accordance therewith. - As seen in FIG. 1, the
control module 192 and thedrive mechanism 170 are positioned in another room such that thecommunication line 210 and thefluid line 188 pass through awall 212 so as to provide explosion protection for the dispensingsystem 10. Alternatively, one or more of thedisplay monitor device 194, themicroprocessor device 196, and thekeyboard 200 could be located next to thedispensing system 10 provided that these components are explosion protected. - In operation, to mix a particular paint formula, the operator of the
semi-automated dispensing system 10 first accesses thecontrol module 192 through thekeyboard 200 to call up the desired paint formula using themicroprocessor device 196 thedata storage device 198. The paint formula (i.e., the liquid paint components 14) is then displayed on thedisplay 195 of thedisplay monitor device 194. The operator then loads thefirst container apparatus 12. - As seen in FIG. 6, to mount (i.e., load) an
original container 16A of aliquid paint component 14 to thereceiving mechanism 98 of the dispensingapparatus 12, the operator of the dispensingsystem 10 first needs to pivot the second engaging mechanism 102 (defined by the L-shapedarms stop member 134 mounted to thesupport frame 80. The operator, while gripping both thehandle member 118 and the handle /stop member 134 to hold the secondengaging mechanism 102 in its unlatched state (against the bias of the spring element 126), then engages thealignment slot 56A of thelid member 20A with theregistration rod 108 of the first engaging mechanism 100 (FIG. 6). Next, while still holding the secondengaging mechanism 102 in its unlatched state, the operator pivots thecontainer 16A andlid member 20A combination clockwise (as viewed in FIG. 6) until the connectingportion 153 of theforce applying mechanism 147 of theoperating device 141 is fully seated in theslot 49A of thecover element 44A, and the latch lugs 43A are fully seated in thelatch slots 115a, 115b of theplates registration rod 108, the connectingportion 153 of theoperating device 141 fully seated in theslot 49A of the cover element, and the latch lugs 43A fully seated in thelatch slots 115a, 115b, the operator pivots the secondengaging mechanism 102 counterclockwise to its latched state, so that the latchingnotches lid member 20A securing theoriginal container 16A lid member 20A combination to thereceiving mechanism 98 the dispensingapparatus 12. To remove thecontainer 16A for the dispensingapparatus 12, this above described process is simply reversed. - The operator then starts the dispensing process using the
keyboard 200 of thecontrol module 192. Since the control module 192 (i.e., microprocessor device 196) is linked to thestepper motor 178 and thesensor 205, thecontrol module 192 controls operation of thestepper motor 178, and thereby movement of thepiston members cover element 44A to dispense (i.e., pour) theliquid paint component 14 from theoriginal container 16A into thepaint receptacle 152. The arrangement of the secondengaging mechanism 102 and the latch lugs 43A prevents movement of thecover element 44A from inadvertently disengaging thealignment slot 56A from thefirst registration rod 108. The weight of theliquid paint component 14 dispensed into thepaint receptacle 152 is monitored by thecontrol module 192 through theweigh cell 190, thereby ensuring an accurate liquid paint component pour. Once the firstliquid paint component 14 is poured, itscontainer paint component container components 14 of the paint formula have been added to thepaint receptacle 152, thereby completing the paint formula mixing process. - This
lid member original container liquid paint component 14 and theresilient seal mechanism 354 prevents contaminants from entering the originalpaint component container cover element interface 356. In addition, theresilient seal mechanism 354 of thelid member paint component 14 out of the pourspout 40A and past thecover element 44A in the closed state of thecover element 44A. Unwanted leakage of just four drops of theliquid paint component 14 from pourspout 40A, when thecontainer dispensing system 10, can result in the addition of 0.1 grams ofunwanted paint component 14 to thepaint receptacle 152 which could require the operator of the dispensingsystem 10 to re-pour other paint components to compensate for this error. Theguide mechanism 470 also helps to prevent undesired leakage of thepaint component 14 out of the pourspout 40A, by ensuring that thecover element 44A is accurately aligned with the pourspout 40A and guided during movement of thecover element 44A between the closed and opened states. Thesecuring mechanism 460 ensures that theseal mechanism 354 is properly and securely mounted to thecover element 44A so as to be unaffected by the attributes of thepaint component 14. - In addition, this
lid member semi-automated dispensing system 10, for dispensingliquid paint components 14 from theiroriginal containers lid member semi-automated dispensing system 10 is easy to use, and does not require a highly skilled operator, since operator interface with thelid members system 10 is substantially limited to identifying the desired paint formula, and loading and unloading theproper containers liquid paint components 14 to and from the dispensingapparatus 12. The operator need no longer manually pour thepaint components 14 from theircontainers liquid paint components 14 from theircontainers vent passage 55A, 55B arrangement prevents liquid paint component from flowing out of the secondopen end 59A, 59B of the vent passage during dispensing of the paint component from thecontainer lid members paint dispensing system 10, makes efficient use of the operator's time, since the operator is free to perform other duties instead of holding thecontainers liquid paint components 14. This efficiency gain allows the operator to mix a greater number of paint formulas during a work day. Lastly, the paintcomponent lid members semi-automated dispensing system 10 comply with all regulations and laws, such as being explosion protected, governing the handling and mixing ofliquid paint components 14 for the duplication of automotive paint formulas. - Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the scope of the invention. For example, although the
lid members semi-automated dispensing system 10 have s been described as useable to dispense liquidautomotive paint components 14 from theiroriginal containers lid members system 10 could be used in laboratory or pharmaceutical organizations to accurately dispense liquid and powdered chemicals according to a desired formula.
