1. A child-resistant closure system for a pump sprayer, comprising:
a cap having a rim at its lower end and including at least one leg extending downward from the rim, the leg including an outwardly projecting vertical protrusion and an outwardly extending horizontal rib, with an undercut provided between the rib and the rim of the cap; a dispensing tip configured to receive the cap thereon, a lower end of the dispensing tip including a horizontal circumferential portion and a pair of finger-depressing shoulders in opposite relation to one another extending horizontally outward from the horizontal circumferential portion, at least one slot defined in the horizontal circumferential portion of the dispensing tip, the slot comprising a wider insertion/removal portion for inserting or removing the leg of the cap therethrough and a narrower locking portion for engaging the leg for locking the cap to the dispensing tip, the dispensing tip having a cylindrical collar provided beneath the shoulders, the collar including at least one button on a vertical facing of the collar, the button comprising a vertical protrusion on an internal side that engages with the vertical protrusion of the leg to prevent rotation of the cap relative to the dispensing tip from a locked condition to an unlocked condition, the button configured to be actuated to enable rotation of the cap relative to the dispensing tip from the locked condition to the unlocked condition so as to enable removal of the cap off of the dispensing tip; and a base secured to the collar of the dispensing tip and secured to a dispenser bottle which contains fluid, the dispenser bottle including a sprayer pump unit which partly extends into an interior of the dispenser bottle and which is actuated by depressing the shoulders on the dispensing tip to spray the fluid within the dispenser bottle; wherein the cap is selectively received by the dispensing tip by inserting the leg of the cap into the wider insertion/removal portion of the slot until the leg contacts the top of the base; wherein the cap is selectively secured to the dispensing dip so as to prevent actuation of the sprayer pump by rotating the cap such that the leg moves from the wider insertion/removal portion of the slot to the narrower locking portion of the slot, such that at least a portion of an edge of the narrower locking portion of the slot engages the undercut provided between the rib of the leg and the rim of the cap, and such that the vertical protrusion of the leg engages with the vertical protrusion on the internal side of a corresponding button; wherein, with the cap in place on the dispensing tip, the leg extends downward through the slot to contact the top of the base so as to allow for the sprayer pump unit to be locked out from operation; and wherein, to remove the cap so as to permit actuation of the sprayer pump unit via the shoulders, the button on the collar is pressed to disengage the vertical protrusion of the leg and the vertical protrusion on the internal side of the button so that the cap may be rotated from the locked condition to the unlocked condition so as to enable removal of cap off of the dispensing tip. |
