Actuator for a dispensing apparatus

摘要

The invention relates to a dispensing apparatus for containing a pressurized composition. The dispensing apparatus comprises a reservoir for containing the composition, a flow conduit in fluid communication with the reservoir having a distal end forming a flow conduit orifice; and a displaceable actuator head comprising a side wall having an interior surface and a dispensing orifice formed through the side wall. An intermediate member having an aperture extending there through is interposed between the interior surface of the displaceable actuator head and the distal end of the flow conduit. The intermediate member is affixed to either the interior surface of the actuator head aligning the aperture with the dispensing orifice or to the distal end of the flow conduit aligning the aperture with the flow conduit orifice. The intermediate member seals the dispensing orifice when the displaceable actuator head is biased to an at-rest position.

主权项

1. A dispensing apparatus for containing a pressurized composition, the dispensing apparatus comprising:
a. a reservoir for containing a composition; b. a flow conduit comprising a proximal end in fluid communication with the reservoir and a distal end forming a flow conduit orifice; c. a displaceable actuator head, the actuator head comprising a side wall having an interior surface, the actuator head forming a dispensing orifice through the side wall; d. an intermediate member having an aperture extending there through, the intermediate member is interposed between the interior surface of the displaceable actuator head and the distal end of the flow conduit, wherein the intermediate member is affixed to the interior surface of the displaceable actuator head aligning the intermediate member aperture with the dispensing orifice of the displaceable actuator head, wherein the intermediate member comprises a thermoplastic material selected from TPE, silicon, or a mixture thereof; wherein the displaceable actuator head is biased to an at-rest position sealing the flow conduit orifice against the intermediate member for the intermediate member affixed to the interior surface of the displaceable actuator head and wherein the displaceable actuator head can be movably actuated to at least partially engage the intermediate member in a dispense position thereby at least partially aligning the dispensing orifice with the flow conduit orifice through the aperture, and a foaming or post foaming composition within said reservoir.
