  • This well known and commercially successful manually operable liquid spraying or jetting device may be equipped with any one of the three embodiments of a seal disclosed hereinafter to thereby convert the dispenser to a leakproof and tamperproof shippable closure in accordance with the present invention.
  • the dispenser or trigger sprayer 10 has a bottle cap 16 adapted to screw onto the threaded spout of a liquid container 102 (FIGS. 1 and 2) to thereby mount the dispenser for operation while attached to the container.
  • cap 16 has the usual annular sealing washer or gasket 104 which provides a liquidtight seal with the upper end of surface spout 100.
  • Dispenser 10 has a dip tube 22 adapted to extend downwardly into container 102 so that its open lower end is positioned near the bottom of the container.
  • dispenser 10 is not equipped with a seal structure 122, 200 or 300 of the present invention as described hereinafter, or that such seals are present but are in their open condition as described hereinafter, that the passages 34, 35 and pump chamber 32 are empty of liquid and filled only with air, and that container 102 is filled with liquid to a level above the lower end of tube 22.
  • trigger 11 is manually squeezed to rapidly force the two-piece piston 12 inwardly of pump chamber 32, the air compressed by the piston will cause inlet check valve 17 to seat and outlet check valve 29 to open to thereby expel a quantity of pressurized air to atmosphere via nozzle orifice 25. If trigger 11 is then released, spring 14 will bias piston 12 back to the outward position thereof shown in FIG.
  • piston 12 due to the need of keeping manufacturing costs as low as possible, merely has a liquidtight sliding seal engagement with the cylinder bore of chamber 32 and is not fully airtight. Rather the piston only has sufficient sealing ability with respect to air to pick up a small head of liquid for the aforementioned self-priming purpose.
  • This inability of piston 12 to pump air above a very low pressure and the resulting leakage of air to the open outer end of the piston bore when the air pressure in chamber 32 is raised slightly above atmospheric pressure seemingly is a deficiency which is utilized to advantage in conjunction with the disabling seal of the present invention as described in more detail hereinafter.
  • Sprayer 10 as disclosed in U.S. Pat. No. 3,06l,202 i.e., without the seal 122, 200 or 300 of the present invention, cannot be used as a closure for container 102 for shipping purposes unless the container is empty of liquid. This is because inlet check valve 17 is lightly biased by spring 19 to open position, and outlet check valve 29 is also only lightly biased by spring 30 to closed position. Hence if container 102 is inverted when full ofliquid, any liquid contained in dip tube 22 will run down hill past valve 17, through passage 34, chamber 32 and passage 35 to valve 29. The stray liquid can then leak around valve 29 into the nozzle passages and then run out of unit 10 through orifice 25. This same condition also exists in a modification of sprayer 10 wherein a metal check ball is substituted for valve 17 and the force of gravity acting on the ball when sprayer 10 is upright is relied upon to lightly bias the ball to closed position.
  • the prior trigger sprayer 10 when sold with a packaged liquid has had to be packaged separately from the container and the container sealed by a separate closure, such as a conventional screw cap.
  • a separate closure such as a conventional screw cap.
  • the liquid dispensing unit 10 is inexpensively converted to a shippable closure by merely adding one simple element thereto; namely, a seal 122, 200 or 300 which closes or covers the nozzle orifice 25, preferably from the exterior side of the orifice, to thereby close liquid and air communication between the orifice and outside atmosphere.
  • FIGS. l illustrate one embodiment of a disabling seal 122 in accordance with the present invention particularly adapted for use with a so-called nonadjustable orifice sprayer of the type presently manufactured by The AFA Corporation of Florida of Miami Lakes, Florida, and sold under the trademark AFA.”
  • sprayer 10 has a nonadjustable nozzle which includes the externally threaded spout 31, a nose bushing 26 press fit in spout 31 and a misting element 28 mounted for limited axial movement in bushing 26.
  • the forward end of element 28 is biased into abutment with an end wall 108 of bushing 26 by spring 30 which also lightly biases valve 29 to closed position.
  • the nozzle spray orifice 25 is formed in an axially thickened conical portion 110 of wall 108.
  • Element 26 has longitudinal exterior ribs (not shown) to 7 provide a clearance space 45 for feeding liquid from the nozzle chamber 112 to the forward end of the bore 114 of bushing 26, from which the liquid is conducted to a whirling chamber 116 by tangentially directed slots 118 in the marginal rib at the forward end of element 28 in a manner similar to that disclosed in the aforementioned U.S. Pat. No. 3,06l,202.
  • bushing 26 Since bushing 26 is press fitted in spout 31, it is held immovable and therefore is set to produce only one spray pattern, and hence this nozzle cannot provide the adjustment disclosed in the aforementioned patent wherein if cap 23 is screwed outwardly on spout 31 the liquid ejection pattern is gradually converted from a spray to a solid stream.
  • cap 23 In this existing nonadjustable nozzle version of sprayer l0, cap 23 merely serves as a retainer for bushing 26, the inner face of the internal end flange 120 of cap 23 normally abutting the exterior end face of bushing 26.
  • these same existing parts of the commercial nonadjustable sprayer described above may be used in cooperation with a disabling seal 122 as best seen in FIGS. 3 and 4 to thereby convert the same to a sprayable closure.
  • Seal 122 comprises a hat-shaped member, preferably injection molded from plastic material such as polypropylene or polyethylene, having a dome-shaped nose portion 124 and a brim portion 126 in the form of a flat annular radially extending external flange, seal 122 preferably being made to scale from FIG. 4.
  • Brim 126 is clamped against the outer face of bushing 26 by flange 120 of cap 23, the cap being screwed down sufficiently tight to provide air and liquid sealing engagement between the interengaged surfaces of brim 126 and bushing 26 as well as between brim 126 and flange 120.
  • brim 126 The outside diameter of brim 126 is slightly smaller than the internal bore of cap 23, and the outside diameter of nose portion 124 at its junction with brim 126 is such that the nose portion has a light press fit through the cylindrical opening 128 nor mally provided in cap 23.
  • seal 122 may be readily preassembled to cap 23 prior to screwing cap 23 onto spout 31 merely by dropping seal 122 nose first into the hollow interior of the cap and pushing the nose of the seal through opening 128 until brim 126 abuts flange 120.
  • the seal and cap subassembly thus is retained as a unit for easy handling during manufacture of sprayer l0 and can be readily assembled to the sprayer by screwing cap 23 on spout 31.
  • a dispenser-closure unit 10-122 is provided which may be screwed onto container 102 with the container partially or completely full ofliquid, and this package can then be shipped without fear of the liquid contents of the container leaking out of the unit even though the same may be inverted and/or the sprayer tampered with; i.e., trigger ll squeezed to reciprocate piston 12.
  • seal 122 is effective to disable the self-priming and liquid pumping capability of the pump mechanism of sprayer 10, thereby rendering it tamperproof and obviating the need for any mechanical lockout structure for trigger 11.
  • Dispenser and the liquid-filled container 102 may be sold as a sealed unit to a customer or ultimate user since it is a very simple matter to unseal the unit and put it to use as a liquid dispenser. This is done by severing the nose portion 124 from the remaining portion of seal 122, as shown by the solid and broken line illustrations thereofin FIG. 4. The nose or tip 124 may be readily cut with a knife along a cut line 132 almost flush with the outer end face of cap 23. The customer may be instructed in how to perform this simple unsealing step by attaching a self-adhering peel-off label 130 (FIG. 1) bearing the legend Cut off with knife associated with a dotted out line 132 on a picture of the sealed nozzle on the label.

  • nozzle spout or nose 202 is not threaded but rather has a smooth cylindrical exterior surface with a circumferential external locking groove 204 therein spaced slightly outwardly from the main body 206 of the spray head.
  • Bushing 26 protrudes from the forward end of nose 202 and is press fitted therein as in the previous embodiment to provide a nonadjustable spray nozzle.
  • a snap-on cap 208 is provided as an integral part of seal 200.
  • Cap 208 has a skirt 210 with an internal circumferential locking rib 212 which, due to the flexibility of skirt 210, can be cammed past nose 202 when cap 208 is pushed open end first onto nose 202. Cap 208 is locked in place when rib 212 reaches groove 204, the resiliency of skirt 210 causing rib 212 to snap into groove 204.
  • the right-hand side of rib 212 (as viewed in FIGS. 7 and 8) is inclined relative to the axis of cap 208 to a greater extent than the left-hand side of rib 212 to facilitate insertion of the cap into thenozzle but to make withdrawal more difficult, this arrangement thus providing a permanent retention of cap 208 on nose 202.
  • seal 200 comprises a cover 220 best seen in FIG. 8 which illustrates the open condition of seal 200.
  • Cover 220 is pivotally connected to cap 208 by a thin flexible strip 222 preferably formed integrally with cap 208 and cover 220 to serve as a so-called living hinge, seal 200 preferably being injection molded in one piece from suitable plastic material such as polypropylene or polyethylene having the capability of unlimited repetitive flexure in portion 222.
  • Cover 220 has a skirt 224 adapted to nest with a squeeze fit over the cylindrical snout 226 of cap 208 when cover 220 is swung upwardly from its dependent open position shown in FIG. 8 to its seal closing position shown in FIG. 7.
  • Cover 220 also has an annular raised rib 228 (FIG.

  • the above-described modified seal 200 thus is effective in the closed position thereof to serve as a disabling seal for the dispenser to convert the same to a shippable closure in the manner of seal 122 described previously.
  • Seal 200 has the additional advantages of being permanently locked into position and being resealable by the ultimate user so that the dispenser may be safely stored between periods of use.
  • Seal 200 may be economically manufactured in one piece by injection molding techniques and is assembled easily to the sprayer during manufacture. Sealing cover 220 snaps securely into closed position and is retained reliably by the internal holding rib 236, thereby achieving a positive and permanent air and liquidtight seal.
  • the heat staked tip 240 locks the sealing cover 220 into permanent tamperproof position so that the consumer must cut the top along the molded notch in order to unsnap the cover and use the dispenser.

No. 3,06l,202.
  • Seal 300 thus has a cap 302 with a skirt 304 slidably received on nose 202 of the spray head, but cap 302 is axially movable along nose 202' to allow for spray pattern adjustment.
  • the sprayer in this version has an O-ring 27 and an open ended bushing 26 through which the misting element 28 projects so as to abut the inner face of a separate nozzle insert 306 which is press fitted into the aperture 307 in the end flange 308 of snout 310 of cap 302.
  • Insert 306 has the spray orifice 25 extending therethrough instead of the spray orifice being formed in the end of bushing 26'.
  • each groove 316 is angled relative to the axis of nose 202' to impart the desired axial travel to cap 302 as the same is rotated on nose 202, and the opposite ends 318 and 318' of groove 316 extend in a plane perpendicular to the axis to provide locking positions to hold the nozzle in either the innermost or outermost (spray or jetting) positions respectively.
  • cap 302 as well as cover 322 are injection molded as one piece from a resilient flexible material, such as polypropylene or polyethylene, so that cap 302 can be pressed open end first onto nose 202' and the follower nubs 314 will snap into groove 316 once they register therewith.
