Definitions

  • This invention relates generally to a manually actuated pump dispenser, and more particularly to a rotatable nozzle assembly for such dispenser capable of being easily and effectively locked in its off position against rotation from such position, thereby rendering the nozzle child-resistant.
  • One of such safety closures is of the "squeeze and turn” cap variety, having a closed end and a flexible skirt.
  • the skirt has one or more internal locking lugs which engage one or more external locking detents on the container neck, the cap being threaded to the neck and being locked when being fully threaded upon such lug/detent engagement.
  • the cap skirt must be inwardly flexed to force its locking lugs radially outward from engagement with the neck detents.
  • U.S. Patent Nos. 3,941,268 and 4,117,945 disclose such safety closures.
  • the closures are not structured for effective use as a nozzle assembly for a pump dispenser.
  • U.S. Patent 4,358,031 discloses a squeeze and turn child-resistant safety closure with a dispensing spout.
  • the closure includes an inner snap cap press-fitted within the closure and snapped onto the outer rim of the container neck.
  • the cap is provided with a dispensing spout which is closed by the outer closure.
  • the nozzle has a discharge orifice in its end wall, and threadedly engages a forward end of the dispenser body for rotation between discharge open and closed positions.
  • a discharge valve element at the forward end of the body seats against the orifice in the discharge closed position.
  • the forward end of the body has one or more external locking detents located adjacent the terminal edge of the nozzle.
  • the nozzle has a flexible skirt portion and a pair of internal locking lugs in engagement with the detents for locking the nozzle against rotation from its discharge closed position.
  • the lugs are disengageable from the detents upon manual application of inward pressure to the skirt portion at locations other than that of the lugs to thereby deform and unlock the nozzle and permit nozzle rotation toward its discharge open position.
  • a nozzle cap is generally designated 10 in Figures 1 and 2, shown mounted on a pump dispenser 11 which may be of the trigger-operated variety having a trigger actuator 12, as disclosed in U.S. Patent 4,204,614, commonly owned herewith.
  • pump dispenser 11 may comprise any of the other known trigger actuated dispensers without departing from the scope of the invention.
  • the dispenser has a body 13 terminating in a forward end 14, having external threads as at 15.
  • the dispenser body includes the discharge passage 16 located adjacent a discharge valve 17 which may be in the form of a needle valve or which may take the form of another type valve element known in the art.
  • Nozzle 10 has an end wall 18 containing a coaxial discharge orifice 19 through which product is dispensed upon pump actuation.
  • the discharge orifice is in communication with discharge passage 16.
  • the nozzle has a slightly tapered annular skirt 21 extending from end wall 18 and terminating in a free edge 22.
  • the skirt is internally threaded as at 23 for thread engagement with external threads 15 for thread mounting the nozzle in place on forward end 14 of the dispenser body.
  • the nozzle In the Figure 2 position, the nozzle is threaded into its discharge closed position at which edge 22 abuts against the forward end of a shroud cover 24 of the dispenser, or against some other portion of the dispenser body.
  • valve 17 is seated against orifice 19 for closing the discharge.
  • a sleeve 25 extends inwardly of end wall 18 and is slightly bulged at its free end as at 26. Bulged end 26 bears against the inner wall of forward end 14 to provide a seal thereat and to form a forward extension of the discharge passage.
  • a pair of arcuate walls are mounted on the inner surface of end wall 18 (only one such wall 27 being shown in Figure 2), and extend a short distance toward valve element 17. These arcuate walls define a swirl chamber surrounding the discharge orifice, and present tangential slots therebetween so that, when fluid is forced into the swirl chamber through these slots, it is caused to rapidly swirl adjacent the discharge orifice before it is discharged outwardly therethrough, all as specifically described in U.S. 4,204,614.
  • Skirt 21 of the nozzle has one or more internal locking lugs 28, such as a pair of such locking lugs spaced 180° apart.
  • the locking lugs may be located adjacent free edge 22 of the nozzle.
  • Forward end 14 of the dispenser body has a corresponding number of external locking detents 29, each having a ledge 31 and being tapered as at 32.
  • skirt portion 33 of the nozzle skirt is sufficiently flexible and deformable in response to the application of manual external pressure.
  • skirt portion 33 is squeezed by applying external pressure, as by the thumb and forefinger, inwardly against the skirt portion, at locations other than that of lugs 28, as illustrated by the arrows in Figure 4.
  • the skirt portion 33 is therefore caused to deform, whereupon lugs 28 shift radially outwardly from engagement with detents 29 for unlocking the nozzle and permitting nozzle rotation in a counter-clockwise direction toward the discharge open position.
  • skirt portion 33 may be spaced a predetermined distance from forward end 14 so as to present an annular gap 34. This will assure that the skirt portion is easily deformed to effect a radial outward shift of lugs 28 for unlocking.
  • This gap may be relatively shallow, since the lug/detent engagement presents but a small overlap, which is all that is required to maintain the nozzle locked in place.
