A nozzle arrangement adapted to be fitted to a pressurized vessel and to permit fluid to be dispensed through it under pressure, is presented. The nozzle arrangement includes a body having an inlet, an outlet, an internal fluid flow passageway through which fluid can flow from the inlet to the outlet, and an actuator portion adapted, upon operation, to engage and open an outlet valve of the pressurized vessel. The nozzle arrangement further includes a resiliently deformable wall member that undergoes a resilient deformation from an initial resiliently-biased configuration to a distended configuration in response to the operation of the actuator portion, and to revert to the initial resiliently-biased configuration when the operation of the actuator portion has ceased and cause any fluid remaining in the passageway to be expelled.

A nozzle arrangement according to claim 1, wherein the outlet is defined, at least in part, by the resiliently deformable wall of the body, which is configured: (a) to undergo a resilient deformation from an initial resiliently-biased configuration, in which the outlet is closed, to a distended configuration, in which fluid can flow through said outlet when fluid is cause to flow through the nozzle arrangement in response to the operation of said actuator portion, (b) to revert to the initial resiliently-biased configuration when the operation of the actuator portion has ceased, said initial resiliently-biased configuration causing any fluid remaining in said outlet to be expelled. 3. A nozzle arrangement according to claim 2, wherein the outlet is an open end of said passageway and the resiliently deformable wall which defines the outlet is the end of the resiliently deformable wall member which defines said substantially the entire length of the internal fluid flow passageway. 4. A nozzle arrangement according to claim 1, wherein the resilience of the resiliently deformable wall member is uniform along its length. 5. A nozzle arrangement according to claim 1, wherein the resiliently deformable wall member is adapted such that, when the operation of the actuator portion has ceased and the resiliently deformable wall reverts to the initial resiliently-biased configuration, any fluid remaining in the passageway is expelled through the outlet. 6. A nozzle arrangement according to claim 1, wherein the resilience of said resiliently deformable wall member varies along its length. 7. A nozzle arrangement according to claim 5, wherein the resilience of the resiliently deformable wall member is greater at locations disposed away from the outlet than at locations proximate to said outlet so that, when operation of the actuator portion has ceased, the internal surface fluid flow passageway resiliently deformable wall elastically recoils to a collapsed configuration at positions further way from the outlet so as to cause any fluid remaining in said portion of the internal passageway to flow towards, and be expelled through, the outlet. 8. A nozzle arrangement according to claim 7, wherein the resiliently deformable wall defines an internal surface which extends for substantially the entire length of the fluid flow passageway, and the resilience of the resiliently deformable wall is greater at an inlet end of the passageway than at positions proximate to said outlet, so that, when the operation of the actuator is ceased, the resiliently deformable wall reverts to the initial resiliently-biased configuration at the inlet so as to cause any fluid remaining in said passageway to flow towards, and be expelled through, the outlet. 9. A nozzle arrangement adapted to be fitted to a pressurized vessel or container and to permit fluid present in said vessel or container to be dispensed through the arrangement under pressure, said nozzle arrangement comprising: a body including, an inlet, an outlet, an internal fluid flow passageway through which fluid can flow from said inlet to said outlet, an actuator portion adapted, upon operation, to engage and open an outlet valve of the pressurized vessel or container to which the arrangement is attached to enable fluid present in the pressurized vessel or container to be released into the nozzle arrangement, and wherein said body comprises a resiliently deformable wall member substantially defining the length of the fluid flow passageway, said resiliently deformable wall member being configured: (a) to undergo a resilient deformation from an initial resiliently-biased configuration, in which the passageway is closed, to a distended configuration, in which fluid can flow through said passageway and be dispensed through the outlet when fluid is caused to flow through the nozzle arrangement in response to the operation of said actuator portion, and (b) to revert to the initial resiliently-biased configuration when the operation of the actuator portion has ceased and thereby cause any fluid remaining in the substantially entire length of the passageway to be expelled, wherein the body comprises two interconnected parts, each of said interconnected parts having respective abutment surfaces which are contacted together, wherein portions of said respective abutment surfaces form walls of the body defining said internal fluid flow passageway, and at least one of said abutment surfaces of said portions forms said resiliently deformable wall member, and wherein a resilience of said resilient deformable wall member increases proportionally with increasing distance from the outlet. 10.
