Abstract
A pressure gauge for an aerosol container includes a scale attached to the container body and a pointer associated with and movable relative to the scale. The pointer is operatively coupled to a valve assembly of the aerosol container. The pointer moves relative to the scale in response to movement of at least a portion of the valve assembly due to internal pressure in the container body to provide a reading.
Claims20
A pressure gauge for an aerosol container including a container body and a valve assembly secured to the container body, the pressure gauge comprising:
- a scale configured to be attached to the aerosol container;
- and
- a pointer associated with and movable relative to the scale, wherein the pointer is configured to be operatively coupled to the valve assembly such that the pointer moves relative to the scale in response to movement of at least a portion of the valve assembly due to internal pressure in the container body to provide a reading.
An aerosol container assembly for a flowable product, the aerosol container assembly comprising:
- a container body defining an interior configured to contain the flowable product under pressure;
- a valve assembly secured to the aerosol container;
- and
- a pressure gauge for detecting the internal pressure in the container body, the pressure gauge including
- a scale attached to the container body;
- and
- a pointer associated with and movable relative to the scale, wherein the pointer is operatively coupled to the valve assembly such that the pointer moves relative to the scale in response to movement of at least a portion of the valve assembly due to internal pressure in the container body to provide a reading.
A dip tube adaptor for an aerosol container that contains a flowable product under pressure using a propellant within an interior of the aerosol container, the aerosol container including a selectively operable valve assembly to allow selective dispensing of the flowable product from the aerosol container and a dip tube, the dip tube adaptor comprising:
- a housing having upper and lower ends, the upper end configured to be coupled to the valve assembly and the lower end configured to be coupled to the dip tube, the housing defining:
- a mixing chamber positioned between the upper and lower ends of the housing, the mixing chamber configured to be in fluid communication with the valve assembly when the upper end of the housing is coupled to the valve assembly;
- a flowable product inlet in fluid communication with the mixing chamber, the flowable product inlet configured to be in fluid communication with the dip tube when the lower end of the housing is coupled to the dip tube;
- and
- at least one propellant inlet in constant fluid communication with the mixing chamber, the at least one propellant inlet configured to be in fluid communication with the interior of the container when the upper end of the housing is coupled to the valve assembly;
- wherein the housing is configured to provide fluid communication between the dip tube and the valve assembly and between the interior and the valve assembly such that when the valve assembly is selectively operated to dispense the flowable product from the aerosol container the flowable product flows into the mixing chamber through the flowable product inlet and, simultaneously therewith, the propellant flows into the mixing chamber through the at least one propellant inlet, wherein the flowable product and propellant mix in the mixing chamber such that the flowable product foams before moving into the valve assembly.
