US12741805 - Dispensing systems, dispensers, and methods of use

The patent describes a dispensing system for pressurized products that features a cap, a translatable nozzle, and an actuator, all designed to work together to control the release of the product. The system includes a biasing member that maintains the actuator and nozzle in an unactuated position until the actuator is fully translated, allowing the nozzle to release the pressurized product through a passageway.

Claim 1

1 . A dispenser comprising: a cap configured to attach to a canister that contains a pressurized product, the cap having a hollow shape that defines a central axial bore and a lower axial opening; a nozzle disposed within the central axial bore of the cap so as to be translatable relative to the cap, the nozzle being configured to attach to a valve stem of the canister, the nozzle comprising a passageway through which the pressurized product is able to pass from the container and be dispersed by the nozzle, the lower axial opening of the cap being sized to enable the nozzle to be inserted into the cap therethrough; an actuator disposed in the central axial bore of the cap so as to be translatable relative to the cap and relative to the nozzle, the lower axial opening of the cap being sized to enable the actuator to be inserted into the cap therethrough; a biasing member operatively interposed between the actuator and the nozzle and generating a biasing force that urges the actuator and the nozzle apart from each other and urges the actuator toward an unactuated position of the dispenser; wherein the dispenser has a partially actuated position and a fully actuated position, the partially actuated position follows a first actuation stage resulting from the actuator being translated toward the valve stem of the canister until the actuator abuts the nozzle without causing the nozzle to translate and therefore without causing the valve stem to translate, and the fully actuated position follows a second actuation stage resulting from the actuator being further translated toward the valve stem to cause the nozzle to simultaneously translate with the actuator and therefore also cause the valve stem to translate and release the pressurized product through the passageway within the nozzle; wherein: the biasing member bears against a bearing surface of the nozzle that causes the biasing member to be flexed and pivoted in the unactuated position of the dispenser; during the first actuation stage a distal end of the biasing member slides along the bearing surface of the nozzle; translating of the actuator during the first actuation stage causes the biasing member to further flex and pivot; and the biasing force generated by the biasing member increases during the first actuation stage and does not increase during the second actuation stage. a cap configured to attach to a canister that contains a pressurized product, the cap having a hollow shape that defines a central axial bore and a lower axial opening; a nozzle disposed within the central axial bore of the cap so as to be translatable relative to the cap, the nozzle being configured to attach to a valve stem of the canister, the nozzle comprising a passageway through which the pressurized product is able to pass from the container and be dispersed by the nozzle, the lower axial opening of the cap being sized to enable the nozzle to be inserted into the cap therethrough; an actuator disposed in the central axial bore of the cap so as to be translatable relative to the cap and relative to the nozzle, the lower axial opening of the cap being sized to enable the actuator to be inserted into the cap therethrough; a biasing member operatively interposed between the actuator and the nozzle and generating a biasing force that urges the actuator and the nozzle apart from each other and urges the actuator toward an unactuated position of the dispenser; wherein the dispenser has a partially actuated position and a fully actuated position, the partially actuated position follows a first actuation stage resulting from the actuator being translated toward the valve stem of the canister until the actuator abuts the nozzle without causing the nozzle to translate and therefore without causing the valve stem to translate, and the fully actuated position follows a second actuation stage resulting from the actuator being further translated toward the valve stem to cause the nozzle to simultaneously translate with the actuator and therefore also cause the valve stem to translate and release the pressurized product through the passageway within the nozzle; wherein: the biasing member bears against a bearing surface of the nozzle that causes the biasing member to be flexed and pivoted in the unactuated position of the dispenser; during the first actuation stage a distal end of the biasing member slides along the bearing surface of the nozzle; translating of the actuator during the first actuation stage causes the biasing member to further flex and pivot; and the biasing force generated by the biasing member increases during the first actuation stage and does not increase during the second actuation stage.
