Definitions

  • the present invention relates to a metering valve that dispenses a predetermined quantity of material from a container, under a dispensing pressure of an aerosol or compressed gas, that is simple in structure and readily manufactured.
  • the present invention further relates to a high flow valve used in conjunction with a compressed gas, an aerosol or in bag-on-valve applications, and particularly to a valve having a housing that is supported by a mounting cup for a product container or can, and communicates with a product or product containment bag inside the can, where the radial opening of the valve is positioned closer to a lower seal of the valve stem rather than an upper seal or mounting cup gasket facilitating an increased flow rate for dispensing the product from the container and valve.
  • the valve stem serves as a metering chamber with a metering device within the valve stem that seals the valve stem from the container in a pre-dispensing position and seals the exit orifice of the chamber after dispensing from the valve stem metering chamber the predetermined quantity of material.
  • Standard aerosol valve and gasket assemblies for dispensing pressurized product from a container have an inherent structural problem which limits the flow rate of product through the valve stem and out of the container.
  • the gasket which seals the conventional radial opening of the spring biased valve in the valve housing of conventional aerosol valves also seals the valve stem with the mounting cup of the container, limiting the diameter of the opening relative to the valve stem extending through the gasket.
  • the valve stem is provided with both an axial and a radial opening for dispensing product from the container.
  • valve stem When the valve stem is depressed inward or pushed down by a user against a spring bias, the radial opening, which is initially blocked by the gasket, is moved into fluid communication with the product contained in the container so that this product is then permitted to flow through the radial opening and out the valve stem and be discharged or dispensed into the environment. Once the user releases the valve stem, the valve stem is automatically returned back into its sealed, closed position with the mounting cup gasket again blocking the radial opening.
  • the FR 1 598 257 A relates to the fractional distribution of substances under pressure as well as a method for dispensing. Furthermore, it also relates to a metering dispenser for dispensing.
  • the structural problem is two-fold; first, the diameter of the radial opening formed in the side all of the valve stem must be smaller than the thickness of the gasket so that the radial opening is adequately covered and sealed in the closed valve position, otherwise there is a substantial risk of the product leaking or flowing into the radial opening and inadvertently able to escape the product contained even when the valve is closed.
  • the thickness of a conventional gasket is typically in the range of 1.02 mm - 1.52 mm (0.04 - 0.06 inches), so that the diameter of the radial opening must be substantially within this range or slightly smaller. This along with tolerances necessary to ensure complete closure of the valve limits the size of the radial opening.
  • valve stem openings create the same or similar structural issues.
  • Collapsible and highly flexible product bags or pouches have become common in different industries for containing a variety of food, beverages, personal care or household care or other similar products.
  • product bags can be used alone to allow a user to manually squeeze and dispense a product from the bag or the product bag may be utilized in combination with a pressurized can and product, for example an aerosol.
  • Such product bags and valves contained in and used with aerosol cans are generally referred to in the aerosol dispensing industry as bag-on-valve (BOV) technology.
  • BOV bag-on-valve
  • These product bags, valves and cans may be designed to receive and dispense a desired product in either a liquid or semi-liquid form which has a consistency so as to be able to be expelled from the valve or outlet by the user when desired.
  • Bag-on-valve technology is known to utilize a product dispenser, such as a can, which has an empty collapsible product bag inserted therein prior to filling of the bag with the desired product to be dispensed.
  • the bag is initially flat and rolled up to form a smaller diameter so as to facilitate axial installation of the bag inside the can with a portion of a filling/dispensing valve communicating with an interior space of the product bag.
  • the product bag is filled with the desired product to be dispensed.
  • a desired product to be dispensed is inserted into the product bag via the two-way valve by conventional filling mechanisms.
  • the product bag expands inside the can.
  • the can is supplied with a pressurized gas, an aerosol or a compressed gas, in order to assist with squeezing the bag to expel the product contents thereof as is well known in the art.
  • a pressurized gas an aerosol or a compressed gas
  • the valve is a key component, which led to the design of multiple valve configurations for a variety of different applications.
  • valve housing engages with a mounting cup of a can, attaches to a bag that holds the product to be dispensed, and provides the framework for the valve stem.
  • the valve stem usually interacts with the interior of the valve housing through the use of a spring.
  • the spring allows the valve stem to move relative to the valve housing to open and close the valve.
  • product to be dispensed flows from the product bag, to and through the valve housing, then through a passage in the valve stem, and finally the product is discharged, via a discharge nozzle of some sort, into the environment.
  • the passage is normally limited in size and shape based on the sealing of the passage by the upper gasket that is used to seal the valve housing to the mounting cup.
  • the various product contents include, for example, liquids, creams, foams, gels, aerosols, colloids, and various other substances.
  • the present invention addresses the required increased flow rate necessary in some bag-on-valve applications, in some aerosol applications, however, the bag- on-valve containers may not be feasible due to volume constraints of the container and cost considerations, even though it may be undesirable to mix the propellant gas with the product material. In these instances, immiscible gases, such as nitrogen or carbon dioxide, may be preferred.
  • the present invention provides for liquefied propellants or compressed gas, such as air, nitrogen or carbon dioxide, to be used and further may provide metered doses of product to be dispensed as required in some aerosol applications.
  • the present invention is directed to a valve used in both conventional and bag-on-valve aerosol container applications that allows a high flow rate of various products, especially viscous substances.
  • the valve includes a valve housing, a valve stem, and a spring or other biasing element that permits the valve stem to move relative to the valve housing.
  • the valve stem is substantially hollow to allow the flow of product to the bag, during the filling process, and to the product to be dispensed from the bag during use.
  • the bag is attached to the valve housing in a conventional fashion. There is a radial bore or bores and a seal near the bottom of the valve stem that dictate the passage and flow rate of pressurized product to be dispensed between the product container and the environment.
  • the radial bore at the bottom or lower portion of the valve stem provides for flow directly from the product reservoir, defined by the bag, to the valve stem passage when a lower seal on the valve is opened.
  • the valve stem passage is sealed by the lower seal or ring which is a separate sealing gasket or ring from the upper gasket.
  • the lower seal may be located anywhere along the valve stem below the upper gasket and preferably at the bottom or lower portion of the valve stem facilitating communication to the product reservoir.
  • the upper portion of the valve stem and upper gasket both refer to the end of the valve stem and the gasket adjacent the orifice in the mounting cup.
  • the lower portion of the valve stem and the lower gasket or ring are spaced from and located axially below the upper portion and generally more interior of the container so that product ejected from the container when the valve is actuated travels from the lower portion of the valve stem past the lower gasket or ring up through the upper portion of the valve stem and out of the valve.
  • a lower sealing gasket or ring allows one or more larger diameter bore(s) to be radially formed in the lower portion of the valve stem without compromising the integrity of the valve stem itself.
  • the bore shape and larger size can be selected to facilitate a high volume flow rate for highly viscous substances.
  • a triangular or polygonal shape bore could provide a variable flow rate into and through the valve stem to ensure that highly viscous materials are dispensed at a desired flow rate, depending on an actuation pressure of a user. It is, therefore, an object of the present invention to overcome the above noted issues and produce a valve for both conventional aerosol valve and bag-on-valve systems which facilitates a high volume flow rate for liquids and semi-liquids of different viscosities.
  • a metering device such as a metal, ceramic or plastic ball is positioned within the valve stem to provide for dispensing a metered dose of product to be dispensed.
  • a metering device such as a metal, ceramic or plastic ball is positioned within the valve stem to provide for dispensing a metered dose of product to be dispensed.
  • the use of a metering device within a metering chamber is well known, with many aerosol valve designs of the prior art showing elaborate, costly and difficult to manufacture mechanisms having one or more mechanical springs, plungers, and other contrivances within the metering chamber to control the movement and positioning of the metering device. What is not shown in the prior art is the placement of the metering device within the valve stem.
  • the location of the sealing ring at the base of the valve stem provides for radial inlet passages to be positioned below a lower sealing rim that using the metering device seals the pre-determined quantity of product within the valve stem from the product within the container.
  • a propellant such as a compressed gas within the container can be used because the propellant acts directly on the metering device to force the metering device through the valve stem and dispense the predetermined quantity of product to be dispensed.
  • the propellant acts directly on the metering device to dispense the pre-determined quantity that is defined by the volume of the valve stem.
  • This volume may therefore be adjusted by changing the length and diameter of the valve stem, which as a single piece may be interchangeable and be easily replaced in the valve housing to provide for larger or smaller required dosage volumes for specific products and applications.
  • the valve stem is initially filled with product to be dispensed through a priming actuation by fully or partially compressing the valve stem.
  • the propellant which may be a compressed gas, forces the ball as a metering device off of a lower sealing rim to travel up and through the valve stem thereby dispensing the quantity of product to be dispensed within the valve stem.
  • the ball engages an upper sealing rim at the outlet orifice of the valve stem to seal and prevent further product from being dispensed to the inlet passage of the actuator and nozzle.
  • valve stem as the metering chamber is therefore filled with the pre-determined quantity of product for dispensing another metered dose.
  • a small conduit may be provided at the upper sealing rim. The conduit provides communication between the valve stem and air external to the aerosol container in order to provide a pressure differential on each side of ball to release the ball from the upper sealing position after the valve is released. It is therefore an object of the invention to provide for a metering device within the valve stem to simplify the assembly and cost of a metering valve.
  • Another object of the present invention is to provide a two-way valve which permits a substantial increase in the speed of filling a product container or bag, especially in the context of highly viscous substances.
  • the present invention relates to a dispensing valve according to claim 1.
  • the present invention also relates to a method of dispensing a product to be dispensed from a dispensing valve according to claim 15.
  • FIG. 1 illustrates a side view of an embodiment not forming part of the present invention depicting the valve 1 in conjunction with the mounting cup 5 for a product containing can or container (not shown) in a bag-on-valve system.
  • the valve stem 7 is arranged parallel to and extends out of the valve housing 3 and through the mounting cup 5.
  • the valve housing 3 has multiple sections or portions that correspond to different functions for the bag-on-valve application.
  • a top portion of the valve housing is engaged with the mounting cup, by crimping, to secure the valve housing 3 to the mounting cup 5.
  • the middle portion of the valve housing 3 accommodates a spring cavity 9, which generally houses a spring for controlling dynamic movement between the valve stem 7 and the valve housing 3.
  • the spring normally biases the valve stem 7 away from a bottom portion 11 of the valve housing 3 into a closed position which prevents the discharge of product from the container.
  • the bottom portion 11 of the valve housing 3 either engages with a dip tube, or as described in this embodiment, with a product bag in the case of a bag-on-valve.
  • a top edge of the product bag (not shown) engages and seals with the bottom portion 11, along a fitment 13, and the valve 1 is utilized to dispense the contents or product to be dispensed from the bag.
  • the valve 1 can be a two-way valve which would allow for product to be dispensed to be inserted into the bag during a filling process as well as dispensed therefrom.
  • the bottom portion 1 1 is better illustrated in the perspective view of FIG. 2 .
  • the fitment 13 on the bottom portion 11 assists in the sealing engagement between the base or bottom portion of the valve housing 3 and the product bag B is more fully described in U.S. Patent Application No. 12/667,423 .
  • This view also shows the entrance to cavity 15 of the valve housing 3 that receives the product to be dispensed from the bag when a user manipulates or operates the valve into an open position to dispense the product.
  • the entrance to cavity 15 may or may not communicate with a dip tube 16 which extends downward info the lower edges and corners of the bag to facilitate complete product dispensing.
  • FIG. 3 A cross-sectional view of a conventional valve 2, according to the prior art, is shown FIG. 3 .
  • the valve 2 is secured to a mounting cup 5 and has a valve stem 8, a valve housing 4, a valve spring 6 and valve gasket 10.
  • the valve 2 is actuated by depressing the valve stem 8 along axis A to a point below the seal of the gasket 10, against a restoring force supplied by the valve spring 6, so that product to be dispensed may commence flowing from the bag B through the product passage 12 and out from the valve container.
  • the gasket 10 also seals the valve housing 4 to the mounting cup 5 to prevent leakage therebetween.
  • the bag B is within the aerosol container 18.
  • the spring 6 normally biases the valve 2 in a normally closed position, as shown, with the opening to the product passage 14 being sealed by and against the gasket 10.
  • the product to be dispensed flows along the valve housing 4, up and around the valve stem 8 and into the product passage 12.
  • the valve 2 may or may not include a dip tube 16 to assist with dispensing product from the bag B.
  • FIGS. 3A and 3B are cross-sectional views of the bag-on-valve embodiment which show the valve housing 3 engaged with the mounting cup 5.
  • An inner gasket 29 is used to form a seal between the valve housing cavity 15, the valve stem 7 and the mounting cup 5.
  • the valve stem 7 extends through the mounting cup 5 and out of the valve housing 3 and is axially biased into a closed position by spring 33.
  • the valve stem 7 is provided with an end sealing portion 23 and a product entrance orifice(s) 21 located adjacent the end sealing portion 23 of the valve stem 7,
  • the valve stem 7 is axially disposed along axis A through the valve and can be made of for example PET, PTFE or other polymer material well known in the art.
  • the valve stem 7 defines a product passage 19 that extends substantially the entire length of the valve stem 7.
  • the product passage 19 commences at a radial bore(s) 21 which is formed adjacent a lower end of the valve stem 7.
  • positioning of the radial bore(s) 21 near the lower end of the valve stem 7 permits a larger bore opening which permits a greater flow of the product content from the bag B and into the product passage 19 and out of the valve stem 7, in comparison to conventional valves, without unduly compromising the integrity of the valve stem 7.
  • valve stem 7 By depressing the valve stem 7 along the axis A, the valve is opened, as shown in FIG. 3A , and product is permitted to flow and is dispensed through a main opening O located at the uppermost end of the valve stem 7.
  • a conventional nozzle, or some other conventional discharge or dispensing device may be supported by the valve stem 7 and communicate with the main opening O for directing or controlling discharge of the product.
  • the end sealing portion 23 At the opposing lower end of the valve stem 7, the end sealing portion 23 has a circumferential notch or channel 25 adjacent the tip 23 that receives a lower sealing ring 31, gasket, o-ring or some other type of seal including an overmolded seal.
  • the valve housing 3 is formed with a respective ledge 26 on an inner wall to provide a sealing edge 24 against which the sealing ring 31 abuts to facilitate closing of the valve and preventing the flow of product to be dispensed from the product bag B while the valve is in a closed position, as shown in FIG. 3B .
  • valve stem 7 is accommodated within the valve housing 3 and biased into the closed position via the spring 33, or some another biasing device, which forces the valve stem 7 axially upward against the gasket and into the closed position with the sealing ring 31 closing the valve against the sealing edge 24. It is to be appreciated that although there is no radial opening or bore in the region of the inner gasket 29, the inner gasket 29 still provides a seal between the valve housing 3, the sliding valve stem 7 and the mounting cup 5 so as to prevent any leakage.
  • the spring 33 maintains the valve stem 7 in the closed position so that the product in the product bag B cannot flow through the valve 1 and be discharged.
  • the spring 33 has an upper end which typically axially engages the valve stem 7 at a lip or stop 27 that extends partially or completely around an outer wall of the valve stem 7.
  • the lower end of the spring 33 is supported by the valve housing 3 at a circumferential edge 28 around the interior wall of the spring cavity 9.
  • the bias provided by the spring 33 allows depression and movement of the valve stem 7 relative to the valve housing 3 so as to enable the valve 1 to be alternately moved between its opened and dosed positions, as shown in FIG. 3A and 3B , respectively.
  • valve stem 7 When the valve is in the open position shown in FIG. 3A , the product to be dispensed is permitted to flow out of the valve and into the environment. The product contents are able to flow from the product bag or container, in through the radial bores 21, along the valve stem 7 and out of the valve 1.
  • the radial bores 21 are located at the lower end of the valve stem 7 adjacent the end sealing portion 23 of the valve stem 7.
  • the radial bores 21 are located immediately axially adjacent the lower sealing ring 31 and the end sealing portion 23 to allow substantially instantaneous flow of the product from the product reservoir through the valve stem 7 and subsequently discharged into the environment without having an intermediary chamber or circuitous flow path through the valve housing.
  • Product ejection occurs when the valve stem 7 is depressed by a user into the open position, moving the valve stem 7 down relative to the valve housing 3 against the bias provided by the spring 33 thereby forcing the lower sealing ring 31 sufficiently away the ledge 26 so as to expose and facilitate direct communication and the radial bore(s) 21 and the fluid contents of either the bag B or the container.
  • FIG. 3A illustrates the open position of the valve 1 that allows the radial bores 21 to communicate directly with a pressurized flow of the product to be dispensed from the product reservoir.
  • Previous valves have been known to locate such bores or openings at or near the upper portion of the valve stem, which limits the size of the passageway due to the inability to effectively shut off flow through a large passage.
  • Flow of the product to be dispensed is interrupted by the lower sealing ring 31, which allows the passages or bores 21 to be significantly larger than passages in previous valves that are positioned near the upper portion of the stem, as opposed to near the lower sealing ring 31.
  • the larger sized radial bores 21, which can be formed greater than 1.02 mm - 1 .52 mm (0.04 - 0.06 in.) in diameter, are formed closer to the lower sealing ring 31 and allow for a higher volume flow rate of product out of the product reservoir to the environment.
  • the bores 21, have a significantly larger diameter than the thickness of the upper inner gasket 29. Because of this significantly larger diameter, relative to known smaller diameters of radial openings adjacent the inner gasket 29, the present invention permits a substantially larger flow rate of product to be dispensed to flow into the valve passage 19, when the valve stem 7 is in a semi or fully open position.
  • FIGS. 4 , 5A, and 5B an embodiment not forming part of the present invention is discussed. It is noted that this embodiment is not a bag-on-valve embodiment such that the fitment for a B-O-V valve is not used and the end sealing portion 23 extends directly into an aerosol container with pressurized fluid product (not shown). It is to be appreciated that a dip tube 16 could also be attached to the end of the valve housing 3 for conventional style aerosol container, as desired or necessary.
  • FIG. 5A shows this embodiment in an open position allowing the product to be dispensed in the product bag to communicate with the valve stem 7 through the bores 35.
  • FIG. 5B shows the valve of this embodiment in a fully closed position with the lower sealing ring 31 preventing the flow of the product to be dispensed into the valve stem 7.
  • the bores 35 in this embodiment are shown having a circular profile as opposed to the straight or rectangular profile shown in FIGS. 3A and 3B .
  • the shape of the bores 35 can facilitate control over dispensing of product at a high flow rate through the valve.
  • FIG. 6 illustrates a side view of the valve stern 7 of this embodiment with the bore 35 having a substantially circular shape.
  • the bore 35 is a radial orifice in the sidewall of the valve stem 7, and adjacent the lower end thereof, which can have a diameter of between about 1.02 mm - 3.81 mm ⁇ 0.04 - 0.15 inches) and more preferably in the range of about 2,03 mm - 3.05 mm (0.08 - 0.12 inches). It is to be appreciated that the larger bores 35 do not significantly affect the structural integrity of the valve stem 7 since the bores 35 are located close to the bottom end of the valve stem 7 where radial forces from depression and actuation of the valve stem 7 by a user are insignificant.
  • the bores 35 are located vertically below the spring 33. It is to be appreciated that axial forces can significantly damage the valve stem where the radial opening is located closer to the top end of the valve stem 7 which the user pushes adjacent the inner gasket 29 as in the known valves.
  • the larger bores 35 permit a high amount of product volume to flow info and through the passage 19 of the valve stem 7 at a high flow rate and eventually be discharged into the environment.
  • the radial bores or passages can be formed in any desired shape or size which facilitates the desired flow rate of the product.
  • the bores can be designed to have a profile and area so that, depending upon how far the valve stem 7 is depressed relative to the sealing edge 24, a desired variable flow rate can be achieved which depends upon the extent that the bore 35 is exposed. Different shapes and sizes may be used for different products to achieve the desired product discharge results.
  • the valve stem 7 may have a radial bore 37 which is shaped as a polygon that gradually increases in area as the valve stem 7 and bore 37 are gradually moved axially relative to the sealing edge 24 of the valve housing 3. In the case of the polygon shown in FIG.
  • valve stem 7 as the valve stem 7 is depressed axially downward relative to the sealing edge 24, a larger cross-sectional area of the polygon bore 37 becomes progressively exposed to the product to be dispensed in the container and thus permits an increase in relative product flow the more the valve stem 7 is depressed.
  • the polygon and circular bores shown in these figures are merely two examples of the type of larger bore shapes, located near or adjacent the bottom end of the valve stem 7 that can readily facilitate dispensing of a larger volume of the product to be dispensed at increased flow rates.
  • the metering device comprises a movable ball 42, or possibly a slidable piston or some other member, located within the valve stem 7.
  • the metering valve 40 includes a conical or tapered lower ball seat or sealing rim 44 which tapers from the slightly larger diameter of the metering chamber 19 to a slightly smaller diameter of an axial inlet passage 46 that communicates with the radial bores 21 for delivering product to be dispensed from the container to the valve stem 7.
  • valve stem 7 also has a conical or tapered upper ball seat or sealing rim 50, located adjacent the outlet orifice 48, and the outlet orifice 48 has a slightly smaller diameter than a diameter of the metering chamber 19.
  • the metering ball 42 has a slightly smaller diameter than the diameter of the metering chamber 19 so as to permit the metering ball to dispense a pre-determined quantity of product to be dispensed, while also facilitating return of the metering ball 42, as discussed below in further detail.
  • a conventional coupling 52 facilitates coupling/interconnection of an inlet passage 74 of an actuator 60 to the free upper end of the valve stem 7.
  • the vertically upper most portion of the valve stem 7 is matingly received by a first end of the conventional coupling 52 while the opposite vertically upper most end of the conventional coupling 52 is received by a lower inlet passage 74 of the actuator 60.
  • the outlet orifice 48, of the valve stem 7 is axially aligned with a vertical first passage 56 formed in the actuator 60.
  • the product to be dispensed may be dispensed from the actuator 60 either radially, as shown, via a substantially horizontal second passageway 58 or substantially vertically (not shown) via a second passageway 58.
  • the substantially horizontal second passageway 58 connects the first passage 56 with a discharge nozzle 62 of the actuator 60 and facilitates dispensing of the product as an aerosol mist, for example.
  • the substantially vertical second passageway 58 is substantially vertically aligned with, or a continuation of, the first passage 56.
  • An actuation or depression area 66 may be provided along a top surface of the actuator housing 64 in order to facilitate depression of both the actuator 60 and the valve stem 7 and actuation of the metered valve 40.
  • An inwardly facing surface of both the upper ball seat or sealing rim 50 and the conventional coupling 52 is typically provided with one, and possibly more, micro groove(s), channel(s) or vent(s) 68.

  • Each micro groove(s), channel(s) or vent(s) 68 has a cross-sectional flow area which is designed to permit external air to flow there along to the upper ball seat or sealing rim 50 and eventually assist with breaking the surface tension seal achieved by the product to be dispensed, between the metering ball 42 and the upper ball seat or sealing ring rim 50.
  • Such cross-sectional flow area is also designed to be sufficiently small so as to prevent any significant amount of the product to be dispensed from flowing out through the micro groove(s), channel(s) or vent(s) 68.
  • the metering chamber 19 typically has a length of between 25.984 ⁇ 2.54 mm (1.023 ⁇ 0.100 inches) and between 8.484 ⁇ 2.54 mm (0.334 ⁇ 0.100 inches) and a diameter of between 3.556 mm (0.140 inches) and between 2.794 mm (0.110 inches), preferably about 3.226 mm (0.127 inches).
  • the metering chamber 19 typically has a volume of between 50 and 100 micrometers, depending upon the particular application. It is to be appreciated that the length and/or the diameter of the metering chamber 19 are designed or selected so as to accommodate the desired predetermined quantity of product to be dispensed during each dispensing cycle of the metering ball 42.
