The end of the arm on the pivoted trigger of a pump dispenser brushes against a projection on the wider end of a funnel-shaped seal to distort the wider end, breaking its seal against the inside of a tubular support for the pump dispenser and opening a vent to the atmosphere.

Pump dispenser having vent valve

Dispenser pump shroud has a forward T-shaped tongue which slides up an incline on rails atop the pump body distorting the nozzle cap and snaps down in front of the forward end of rails leaving an upward hook extending through an opening in the cap.

Pump dispenser having shroud locking means

Dispenser pump shroud has forward T-shaped tongue which slides up incline on rails atop the pump body distorting the nozzle cap and snaps down in front of the forward end of rails leaving an upward hook extending through an opening in the cap.

Outward flanges on top of pump outlet tube include a rearward latching section. A rearwardly extending horizontal shelf is formed on the vertical tubular support of the pump body. The shroud is open-fronted and includes a top wall, connected side walls and a rear end wall with an inward horizontal shoulder. Extending downward along the top wall of the shroud are a pair of opposed channels to the rear of which are unitary downward locking wedges. In assembly, the open-fronted shroud is moved forward onto the pump body in a simple unidirectional linear movement, the channels receiving the outward flanges respectively. The latching sections are flexed downward by the locking wedges and snap past them and the shoulder on the shroud slides under the shelf.

Dispensing pump having universal pump body and readily attachable shroud

An attachable shroud and a dispensing pump with universal pump body upon which is formed outward flanges on top of a pump outlet tube which includes a rearward latching section. A rearwardly extending horizontal shelf is formed on the vertical tubular support of the pump body. The shroud is open-fronted and includes a top wall, connected side walls and a rear end wall with an inward horizontal shoulder. Extending downward along the top wall of the shroud are a pair of opposed channels to the rear of which are unitary downward locking wedges. In assembly, the open-fronted shroud is moved forward onto the pump body in a simple uni-directional linear movement, the channels receiving the outward flanges respectively. The latching sections are flexed downward by the locking wedges and snap past the wedges and the shoulder as the shroud slides under the shelf.
