Definitions

  • the upparatus comprises a pump including means for positively locking and sealing the pump in position on the canister in surrounding relation to the valve assembly such that said pump may be operated to withdraw liquid from a source and inject said liquid under pressure into said canister.
  • the novel pump apparatus employs a check valve which precludes back flow during the injection procedure.
  • This invention relates to a pump assembly which can be used to inject a small quantity of a liquid or liquidlike substance into a pressurized aerosol container.
  • the aerosol can or similar container is a very popular packaging means for supplying a relatively small quantity of a sprayable material in a convenient form for use by the ultimate consumer. Aerosol cans are widely used for a wide variety of products, such as paints and other protective coatings, hair sprays, personal products, and the like.
  • the typical aerosol container is a Iight-weight sheet metal can provided with a valve at its upper end surrounded by an upstanding circular rim. The valve is biased by an internal spring which presses the valve components into sealing engagement. To operate the valve, a short length of a hollow tube is forced into the valve, opposing the action of the biasing spring, thereby opening the valve and permittingthe enclosed propellant to discharge the contents of the can in the form of a fine spray.
  • the pump assembly of the invention permits such additions to be made to pressurized aerosol cans in a simple, economical, and safe manner.
  • the pump assembly has built-in safeguards which prevent its operation unless it is properly locked to the can, so that the proper seal is always maintained. If for any reason the adjustment of the pump assembly to the can is improper, the can valve remains closed under its own pressure and no loss of its contents can occur.
  • FIG. I is a front view in partial section of the pump assembly in locked position onto an aerosol can shown in fragmentary view;
  • FIG. 2 is an exploded view of the parts of the assembly, showing the locknut in position on an aerosol can and the pump body before it is inserted into the locknut to complete the assembly;
  • FIG. 3 is a sectional view along the line 3-3 of FIG. 1;
  • FIG. 4 is a sectional view along the line 4-4 of FIG. 1;
  • FIG. 5 is a bottom view of the plunger piston shown in partial section in FIG. 1;
  • FIG. 6 is a bottom view of the locknut assembly shown in position on an aerosol can in FIG. 2.
  • the pump assembly comprises three major components, housing 11, plunger 31 and locknut 51.
  • Plunger 31 and a portion of housing 11 cooperate to form the pump proper, while locknut 51 serves to lock the pump assembly onto the neck of an aerosol can 61.
  • housing 11 comprises a base plate 12 to one end of which is attached a screw cap 13 into which is screwed vial 14 containing the material 15 to be added to the aerosol can.
  • the other end of base plate 12 is connected to pump body 16, which as shown in FIG. 1 is a cylindrical body closed at its lower end by plate 17 and provided with a circular sleeve 18 which extends downwardly around the perimeter of the body.
  • Cylindrical pumping chamber 19 is concentrically located within body 16, the respective walls of the pumping chamber and the body forming an annular space 21.
  • the top of chamber 19 is open, while the bottom is drawn to an elongated noule 25.
  • plunger 31 Fitted within housing 11 is plunger 31, the upper end of which is a flattened head 32 which is connected to circular plate 33 by means of vertical plates 34 and 35.
  • the lower portion of plunger 31 contains a cylindrical portion 36 containing a bore 37 into which is fitted plug 38 and check valve ball 39.
  • the upper end of the bore 37 is formed as a valve seat 41 with which check valve ball 39 cooperates to seal the bore against the flow of liquid in an upward direction.
  • Plug 38 contains a cylindrical body portion 38a to which are attached a plurality of elongated ribs 38b which are deformed when the plug 38 is inserted into bore 37 to make a permanent pressed fit. Ribs 38b also define longitudinal annular channels for the flow of liquid within bore 37. The lower portion of plug 38 is a flattened 51 serves to lock the pump assembly onto the neck of an aerosol can 61.
  • housing 1 1 comprises a base plate 12 to one end of which is attached a screwcap 13 into which is screwed vial 14 containing the material 15 to be added to the aerosol can.
  • the other end of base plate 12 is connected to pump body 16, which as shown in FIG. 1 is a cylindrical body closed at its lower end by plate 17 and provided with a circular sleeve 18 which extends downwardly around the perimeter of the body.
  • Cylindrical pumping chamber 19 is concentrically located within body 16, the respective walls of the pumping chamber and the body forming an annular space 21.
  • the top of chamber 19 is open, while the bottom is drawn to an elongated nozzle 25.
  • plunger 31 Fitted within housing 11 is plunger 31, the upper end of which is a flattened head 32 which is connected to circular plate 33 by means of vertical plates 34 and 35.
  • the lower portion of plunger 31 contains a cylindrical portion 36 containing a bore 37 into which is fitted plug 38 and check valve ball 39, which has a density less than that of the liquid to be pumped.
  • the upper end of the bore 37 is formed as a valve seat 41 with which check valve ball 39 cooperates to seal the bore against the flow of liquid in an upward direction.
  • Plug 38 contains a cylindrical body portion 38a to which are attached a plurality of elongated ribs 38b which are deformed when the plug 38 is inserted into bore 37 to make a permanent pressed fit. Ribs 38b also define longitudinal annular channels for the flow of liquid within bore 37.
  • the lower portion of plug 38 is a flattened circular plate 38c which is perforated (see FIG. 3) to permit liquid within bore 37 to pass into the interior of pumping chamber 19.
  • Adjacent the lower end of cylindrical portion 36 of plunger 31 is a circumferential rib 360 which with plate 380 defines a groove containing O-ring 36b which is in sealing engagement with the wall of pumping chamber 19.
  • helical return spring 42 which biases plunger 31 in an upward direction.
  • the upward travel of plunger 31 is limited by radial lugs 33a which protrude into vertical slots 22 and 23 (see FIG. 4) diametrically located opposite each other in the wall of body 16.
  • connection between pump body 16 and base plate 12 is strengthened by vertical, approximately triangular plates 26 and 27.
  • a horizontal tubular receiver 43 which accepts one end of flexible tubing 44, the other end of which passes through screwcap 13 and acts as a dip tube 24 in vial 14 containing the liquid or liquidlike substance 15 to be added to the aerosol container.
  • a passage for liquid flow from the end of tubing 44 in receiver 43 is provided by channels 46 and 47 to check valve seat 41 and thence to the bore 37 of plunger 31.
  • the wall section of housing 11 between plates 26 and 27 and above base plate 12 is cut away, as shown, to provide clearance for receiver 43 on vertical movement of plunger 31.
  • locknut 51 In order to lock the pump assembly securely onto the aerosol can 71 with which it is to be used, locknut 51 is employed.
  • Locknut 51 is generally cylindrical in shape, and is provided in its upper portion with internal threads 52 adapted to receive the partial threads 28 on diametrically opposite sides of the exterior of body 16.
  • Vertical ribs 53 provide a gripping surface for rotation of the nut.
  • locknut 61 in its lower portion, locknut 61 is provided with a pair of opposed locking wings 54 defined in part by slots 56. The locking wings 54 are deformable to clear the upstanding rim 72 of the can 71 and to engage the undercut portion of the cans rim when the locknut is put in position on the valve of an aerosol can.
  • injection nozzle 25 has entered the discharge opening of the cans valve into contact with resilient sealing pad 76, which forms an atmospheric seal around the perimeter of nozzle 25. As shown in FIG. 2, injection nozzle 25 has a length which is insufficient to open the valve 73 of the aerosol.
  • plunger 31 creates a partial vacuum in pumping chamber 19 which produces a syphon effect, drawing liquid from vial 14 through tube 44 and channels 46 and 47 and check valve 41 and into the bore 37 of plunger 31.
  • the liquid passes through the channels defined by cylinder 38a and ribs 38b, through the openings in the plate 380, and into the pumping chamber 19.
  • the initial downward movement of plunger causes check valve ball 39 to rise because of the hydraulic impact of the liquid into sealing engagement with seat 41, thus preventing the escape of the liquid from the pumping chamber.
  • the construction of the pump assembly of the invention has a number of built-in safety features.
  • housing 11 in order to establish a sealing relationship between injection nozzle 25 and the valve member 73 of the can, housing 11 must be fully inserted into locknut 51, thereby locking wings 54 into engagement with the rim of the can. Accordingly, until the assembly has been locked into position, the device is inoperative since a seal must be established at the end of injection nozzle 25 before a vacuum can be established in pumping chamber 19 in order to draw over any of the liquid to be added to the can. lf at any point the downward stroke of plunger 31 is stopped, the reduced pressure in pumping chamber 19 permits the valve 73 of the can to close immediately, thus preventing the loss of the contents of the can.
  • the pump assembly of the invention cannot pressurize the aerosol can by pumping air after the contents of vial 14 are exhausted.
  • the presence of liquid in pumping chamber 19 is necessary in order to actuate check valve ball 39.
  • the pump assembly cannot be used to pump a dangerous amount of air into the can.
  • the pump assembly of the invention may be constructed of any material which is adequately strong and rigid to withstand the imposed stresses while being impervious to the liquid materials with which it comes into contact.
  • a suitable material is nylon or a similar plastic, which is strong yet somewhat resilient, pennitting slight deformation which facilitates the assembly of the individual parts.
  • the pump assembly of the invention permits great flexibility in the use of the product.
  • a paint retailer need only stock a supply of pressurized cans containing paint of a neutral color, to which he or the user can add the desired pigments or colors before use, thus greatly reducing his inventory space requirements.
  • the device of the invention permits the convenience of aerosol packaging to be applied to certain synthetic polymeric materials, such as polyesters, polyamides, polyurethanes, epoxies, and the like which cure to form a hard or tough material on the addition of a catalyst material which initiates a chemical reaction.
  • a pumping means located within said housing means, said pumping means including an inlet means and an outlet means;
  • first liquid flow path means located within said housing wherein said first liquid flow path provides a means for transferring said liquid from said liquid container to said inlet means;
  • second liquid flow path means located within said housing between said outlet means and said aerosol container, said second liquid flow path means being adapted to cooperate with the valve of said aerosol container to effect a vacuum seal and to allow a vacuum to be drawn in said pumping means;
  • a check valve means located within said first liquid flow path means for controlling the flow of liquid therethrough;
  • locking means for locking said housing means to said aerosol container while said assembly is in operation.
  • said pumping means comprises a pumping chamber located within said housing means, said pumping chamber having its top end open and its bottom end reduced to an elongated nozzle; and a plunger piston slidably positioned within and in sealing engagement with the wall of said pumping chamber.
  • check valve means is adapted to be actuated by the presence of said liquidlike substance within said pumping chamber in order to close said inlet.
  • said locking means comprises a cylindrical sleeve attached to the lower end of said housing means and-a locknut threadedly engaging said housing means and encircling said sleeve, said nut being pro vided with a plurality of flexible undercut wings which are outwardly biased into locking engagement with said aerosol container by axial relative movement of said sleeve on rotation of said nut.
  • said plunger has a longitudinal bore, the upper end of which serves as the inlet to said pumping means, a movable sealing ball within said bore which cooperates with the upper end of said bore to seal said inlet, and a plug inserted into the lower end of said bore to limit the free movement of said ball, said plug being provided with openings permitting the flow of liquid from said bore into said pumping chamber.
