Abstract

An actuator tip diffuser may be retrofitted onto existing pump dispensers to create a scatter flow. The scatter flow can be induced by using patterns with larger area sections produce separate, individual streams. Increasing the length of the orifice adapter and adding a center outer ring also reduced spatter. In all instances, the actuator tip diffuser includes a through-channel, with an inlet fitted to the existing actuator nozzle on one end and a downwardly disposed outlet for discharging fluid via the pattern of orifices/structure noted above. The tip may also include one or more retainer tabs to create a snap fitting to existing dispenser pumps.

Claims (31)

1. A dispensing system comprising:

a fluid container with an opening;

an actuator pump having a dispensing channel, said actuator pump coupled to the opening;

a selectively detachable diffuser head fitted to and partially held within the dispensing channel, said diffuser head having a downward-facing outlet divided into an array of teardrop-shaped apertures and wherein each aperture is evenly spaced from:

(i) a central axis of a flow channel defined by the diffuser head, and

(ii) all adjacent apertures, and

wherein the array conforms to a periphery of the outlet to divide fluid flowing thereform.

2. The system of claim 1 wherein there are 5 or 6 apertures.

3. The system of claim 1 wherein each aperture in the array has an identical surface area and shape.

4. The system of claim 1 further comprising a central post held concentrically within the outlet by way of one or more connecting bridges spanning an inner facing of the outlet.

5. The system of claim 1 further comprising a hollow, tubular ring on the diffuser head proximate to the outlet by way of one or more connecting bridges spanning an inner facing of the outlet.

6. The system of claim 5 wherein the ring is flush with an outer facing of the diffuser head at the outlet.

7. The dispensing system according to claim 1 wherein the array is arranged in a circular pattern.

8. A dispensing system comprising:

a fluid container with an opening;

an actuator pump having a dispensing channel, said actuator pump coupled to the opening;

a selectively detachable diffuser head fitted to and partially held within the dispensing channel, said diffuser head having:

(i) a downward-facing outlet divided into an array of apertures centered and evenly spaced around the periphery of the outlet to divide fluid flowing thereform,

(ii) a diffuser body,

(iii) one or more connecting bridges connected to the diffuser body and defining the array of apertures, and

(iv) a ring secured to at least one of the one or more connecting bridges and extending downwardly and away from the dispensing channel and outlet.

9. The system according to claim 8 further comprising a central post held concentrically within and aligned along an axis of the flow channel, said post secured to at least one of the one or more connecting bridges and spaced apart from the ring to create a flow path therebetween.

10. A dispensing system comprising:

a fluid container with an opening;

an actuator pump having a dispensing channel, said actuator pump coupled to the opening;

a selectively detachable diffuser head fitted to and partially held within the dispensing channel, said diffuser head having:

(i) a downward-facing outlet divided into an array of apertures centered and evenly spaced around the periphery of the outlet to divide fluid flowing therefrom,

(ii) a diffuser body,

(iii) one or more connecting bridges connected to the diffuser body and defining the array of apertures,

(iv) a ring secured to at least one of the one or more connecting bridges and extending downwardly and away from the dispensing channel and outlet, and

(v) a central post held concentrically within and aligned along an axis of the flow channel, secured to at least one of the one or more connecting bridges, and spaced apart from the ring to create a flow path therebetween.
