Broken or clogged aerosol dispenser recovery tool

Abstract

An Aerosol salvage tool used for tapping and dispensing, for their intended use, aerosol products that have had their original dispensing actuators or nozzles broken or disabled. This tool comprises two separately formed handles pivotally attached to each other which form an adjustable circular containment for an aerosol container. This allows for multiple size aerosol containers to fit within the tool. One of the handles has a container piercing member mounted thereon. As the handles are pivoted towards each other the inside diameter closes in engaging the piercing member and aerosol container thereby piercing the container allowing it's content to flow through the member into it's spray actuator and nozzle. Simultaneously as the handles are drawn toward each other a staged locking devise and safety lock engages holding the tool in place on the container thereby preventing the tool from being released accidentally.

BACKGROUND OF THE INVENTION

(1) Field of the Invention

For many years aerosols have been an integral part of most everyone's daily lives for the delivery and dispensing of many products such as deodorants, hair sprays, medications, air fresheners, cleaners, lubricants, paints, insecticides, and many other products that are used daily all over the world. Since the first aerosol product dispensers were produced they have been plagued with various negative conditions which in most cases render the dispenser and it's product unusable. The most common of these conditions is a clogged spray actuator and/or nozzle, this condition is commonly caused by periods of storage or non-use. Another common cause for a disabled aerosol product is, many aerosol dispensers get accidentally dropped or mishandled which can cause the spray actuator and/or nozzle to break disabling it. Probably the most common problem is when the spray nozzle itself gets lost or misplaced, this condition only renders the product unusable when a suitable nozzle cannot be found to replace the lost or misplaced nozzle.

Aerosol products are packaged and marketed in convenient and economical cylindrical shaped metal vessels. These vessels come in many different sizes in diameter, height, and volume. Aerosols are typically pressurized with some form of gas or propellant that pushes it's content up through a dip tube into a spray actuator and spray nozzle, that when depressed by it's operator, delivers the content at a rate determined by the products application and/or use.

This invention was conceived by an inventor who has worked in the automotive industry for over 25 years. During that time he has seen an incredible amount of aerosol products being thrown away because their spray nozzles and/or actuators became broken or clogged. The problem was not only the wasted product, but the time involved in replacing the products was time consuming and costly. It also seemed a huge waste of resources sending unused aerosol products to a landfill, not to mention most aerosol products are toxic and/or have a negative environmental impact.

It is clear this invention will have a positive impact economically and environmentally by allowing for the intended use of aerosol products saving in resources, and preventing these products from polluting landfills and/or other such waste containments. Clearly this invention is a tool that will help to solve these problems in a positive way.

(2) Description of the Related Art

There are many inventions with patents issued for aerosol container evacuation for safe disposal. Many of these patents appear to be for large scale or multiple aerosol container processing (examples include: O'Neil U.S. Pat. No. 5,322,093, Cound U.S. Pat. No. 4,459,906, Gonzalez-Miller U.S. Pat. No. 5,174,344, Nash U.S. Pat. No. 5,088,526) which appear impractical because of the huge variety of aerosol products that can't or shouldn't be mixed during the evacuation process. There are also many patents issued for single container evacuation for disposal (examples include: Rubenic U.S. Pat. No. 6,481,470, Iglesis U.S. Pat. No. 4,428,510). These inventions address the evacuation and disposal issue, but none that allows for the consumer to immediately use the product for it's intended purpose. I was able to find two patents for pressurized vessel piercing tools, (Robertson U.S. Pat. No. 4,852,769, and Dudley U.S. Pat. No. RE41,263), both of which are for piercing and dispensing automotive Freon cans. The first one Robertson, is the tool the inventor used to make a working prototype shown in FIG. 1 of the drawings. Both of these patents are currently manufactured and sold, but neither are used or marketed for the salvage and use of disabled aerosol products.

Many of the classifications and subclasses provided for by the USPTO describe or can be applied either all or in part to the features found in this invention. I find the following U.S. patent classifications applicable to this invention:

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1 and 2, The photo and illustration for FIGS. 1 and 2 represent the inventors preferred embodiments for this invention.

FIG. 1, is a photograph of an actual working prototype assembled by the inventor as the need for this invention became apparent. Pictured is an automotive Freon “tap tool” with a few common pipe fittings and a spray actuator/nozzle, gathered and assembled by the inventor. This embodiment represents the idea of a simple tool cast in a one piece design that fit's a most common aerosol container diameter (2⅝″) which can be produced inexpensively as a disposable or reusable tool dependant on the care taken in use and/or variety of product it is used to dispense. It is to be understood that various embodiments of this invention may be utilized without departing from the scope and principles of this invention.

FIG. 2, represents a tool 1 that is diversely adjustable to fit any size aerosol container and has a receiver 19 that allows for placement or replacement of an actuator/nozzle 2 and/or interchangeable pump attachment 3 in case the need arises to use an aerosol product with content but void of propellant or pressure. This invention comprises of two generally symmetrical handles 13a,13b, formed with two generally semi-circular receiving surfaces 6,7, which pivot on a hinge 10 that joins the two handles 13a,13b, at the ends of the receiver portions 6,7, of the handles 13a,13b. Co-acting with the hinge 10 is a spring 16 that urges the handles 13a,13b apart upon release of the tool 1 from a closed position. Attached to the inside portion 44 of handle 13a is a fine toothed rack 11, that engages a pawl 12 attached to the inside portion 45 of the opposite handle 13b. At the top of the pawl 12 just below the receiver portion 6 of handle 13b is a pin 15 anchoring the pawl 12 through a hole 34, allowing the pawl 12 to pivot slightly on the pin 15, located at top of the pawl 12 just below the pin 15 is a pawl tension spring 14 that holds the pawl 12 engaged to the rack 11, thereby holding closed positions of the tool 1. Located on the pawl 12 just below the pawl tension spring 14 is a rack opening 36 which positions the rack 11, and allows for it's travel through the pawl 12, as the handles 13a,13b, are squeezed toward each other, the pawl tension spring 14 holds the pawl 12 engaged with the rack 11, as it clicks holding each closing adjustment as the receiver surfaces 6 and 7, close in onto the container. To release the tool 1 from it's lock positions the pawl 12 is simply pulled toward the inner surface 44 of handle 13b.

FIG. 2 a, is a side view of the handle 13a side of the tool 1 standing on end. FIG. 2a also provides a view of the outer surface 5 of handle 13b giving a general idea for placement of the male barbed connector 19 in handle 13b, and a general idea for the placement of the hinge 10 that attaches handles 13a and 13b. Additionally provided in FIGS. 2 and 2a, are measurements for the disclosed embodiment to be considered a reference for the general size of this tool 1. Represented in FIG. 4, is a cut-away view of the receiver portion of handle 13b near the hinge 10. Projecting inward on the receiving surface 6 is a piercing tube 17. Recessed 49 slightly into the receiver surface 6 of handle 13b, and surrounding the piercing tube 17 is a container sealing gasket 18. For illustrative purposes the piercing tube is represented in the illustrations as hollow and needle shaped, and protruding from the gasket 18. Preferably the gasket 18 contacts the container surface just before or simultaneously with the piercing tube 17, thus preventing any leakage upon engagement of the tool 1. Part of and in continuation of the piercing tube 17 extending through the inner surface 6 and outer surface 5 of the receiver portion of handle 13b is a male barbed connector 19 which has a threaded opening 4 in the end opposite of the piercing tube 17. This threaded opening 4 is fitted with a Schrader valve 20. Those familiar in the art know a Schrader valve shuts off the flow of air, gases, or fluids and the like until the valve is actuated.

FIG. 5, is a cut-away view of the Schrader valve 20 in place in the threaded opening 4 of the male barbed connector 19. FIG. 5 also provides a cut-away view of the piercing tube 17 and male barbed connector 19 as a one piece member.

Represented in FIGS. 8-11 are the Safety Lock Features. Below the rack opening 36 in the pawl 12 is a safety lock lever opening 38, incorporated into this opening 38 are two spindles 41 that allow the safety lock lever 39 to pivot in and out of the locked position. Incorporated onto the safety lock lever 39 is a thumb or finger knob 37 to allow the operator to flip the lever 39 out of a locked position, which is held automatically into the locked position by the safety lock spring 40. On either side near the thumb knob 37 of the safety lock lever 39 are two holes 42 that fits between the spindles 41 in the lever opening 38. Incorporated into the lever opening 38 and the safety lock lever 39 is a spring 40 that urges the lever into the locked position, requiring an effort to disengage the rack 11 and pawl 12 from the locked position, this prevents an accidental release of the tool 1 from an aerosol container.

Represented in FIG. 6 is a spray actuator/nozzle assembly 2, this assembly 2 has a circular shaped female barbed receiver portion 9. This receiver portion 9 is clearly shown from the receiving end in FIG. 6a, the receiver portion 9 comprises of two female barbed connectors 29 on either side of the receiver 9 circumference. As the female receiver 9 is engaged with the male barbed connector 19 the female connectors 29 lock under the lip 46 of the male barbed connector 19. As the female connectors 29 lock under the lip 46 an O-ring 47 located in the receiver 9 seals against the tapered portion 48 of the male barbed connector 19. Between the female connectors 29 on either side of the receiver 9 circumference are two release points 31 that when squeezed toward each other spread the female connectors 29 apart to allow installing or releasing of a receiver 9 from the male barbed connector 19. As the female receiver 9 is snapped onto the male barbed connector 19 an appendage 27 in the center of the female receiver 9 engages the Schrader valve 20 releasing the flow of the aerosol product into the spray actuator/nozzle assembly 2. With the actuator/nozzle in place the operator can now use the tool 1 by using the finger grips 32 to depress the nozzle 22 releasing the containers content for it's intended purpose.

FIG. 7, illustrates an interchangeable hand operated pump 3 that is used in the case of an aerosol container void of pressure but with useable content. This pump attachment 3 is interchangeable with the actuator/nozzle assembly 2. It is comprised of a circular shaped female barbed receiver 9 and two female barbed connectors 29. This receiver portion 9 is clearly shown from the receiving end in FIG. 6a, the receiver portion 9 comprises of two barbed connectors 29 on either side of the receivers 9 circumference. As the female receiver 9 is engaged with the male barbed connector 19 the female connectors 29 lock under the lip 46 of the male barbed connector 19. As the female connectors 29 lock under the lip 46 an O-ring 47 located in the receiver 9 seals against the tapered portion 48 of the male barbed connector 19. Between the female connectors 29 on either side of the receivers 9 circumference are two release points 31 that when squeezed toward each other spread the female connectors 29 apart, for installing or releasing the receiver 9 from the male barbed connector 19. As the female receiver 9 is snapped onto the male barbed connector 19 an appendage 27 in the center of the female receiver 9 engages the Schrader valve 20. With the pump attachment 3 in place the operator can use the finger grips 32 to aid in depressing the pump shaft and thumb rest to pump pressure into the aerosol container.

Much of the forgoing describes a tool 1 that is made to receive replaceable and/or interchangeable components, it is obvious that this tool 1 could be conceived with a fixed spray actuator and nozzle eliminating a certain degree of complications as illustrated in FIG. 1. Changes, alterations, and modifications of this invention are only limited by the imagination, In light of the illustrations and descriptions of this invention the spirit, scope, principles, and it's contributing usefulness should be clearly understood.
