A puffer device includes a cabinet having a printed circuit board and a gear train assembly coupled to the printed circuit board. The gear train assembly includes a motor and a gear driven by the motor. A cam is coupled to the gear. The cabinet further includes a plunger configured to be contacted and driven by the cam. The puffer device further includes an aerosol can assembly configured to be releasably coupled to the cabinet, wherein movement of the plunger is configured to dispense a material from the aerosol can assembly.

A remotely controlled attractant or repellent dispersing apparatus housing a remotely controlled actuator system where an aerosol spray can is mountable for engagement with the actuator system. A receiver in communication with a transmitter is configured to receive one or more commands from the transmitter and relay the command to the actuator system for opening and/or closing a valve on the spray can for dispersing the contents of the aerosol can at selected times and for selected durations. The dispersing system is mountable in an outdoor environment and the transmitter is a hand-held remote control. A removable base support is provided to retain aerosol spray cans of different sizes in alignment with the actuator system.

An aerosol dispenser, outer container for an aerosol dispenser and a preform for an outer container, each include an open neck at the top and a closed end bottom. The open neck may include a first surface having a first surface diameter, a second surface disposed interior to the first surface and having a second surface diameter less than the first surface diameter, and a transition distinguishing the first surface from the second surface. For a dispenser and a container, a product delivery device may be disposed on the second surface and not interfere with a valve operable by a user when the valve is attached to the open neck in engagement with the first surface. At least one of the first and the second surfaces may be a sealing surface to prevent escape of propellant from the outer container to ambient when a valve is attached.

An automated flowable material dispenser for dispensing flowable material from a flowable material container is provided. In one embodiment, the dispenser may include a dispenser housing configured to receive the flowable material container therein, a solenoid valve assembly positioned within the dispenser housing, and a biasing member configured to bias the flowable material container toward the solenoid valve assembly and to move the flowable material container from an unactuated configuration to an actuated configuration. The dispenser housing may define a dispensing opening along a bottom end of the dispenser housing and may be configured to move between an open configuration and a closed configuration. The solenoid valve assembly may be positioned above the dispensing opening and configured to control dispensing of the flowable material from the dispenser.

The present invention relates to a method for manufacturing a pressurizable cylindrical vessel for use in a pressure control system for maintaining a constant predetermined pressure in a fluid container configured to dispense when in use a fluid contained in said fluid container at said constant predetermined pressure, characterized in that the manufacturing is by injection moulding. The invention also relates to a method for assembling a pressurizable fluid container configured to dispense when in use a fluid contained in said container at a constant predetermined pressure. In addition, the invention relates to a pressurizable cylindrical vessel, a pressurizable unit, a pressure control system, a bottom plate and a dispenser; as well as their methods of manufacturing. In a final aspect the invention relates to uses of said parts in a bag-on-valve type packaging or metal can type packaging.

A plural preform assembly having nested preforms. The preforms are held together by an interference fit. The interference fit is provided by the friction between the preforms which occurs when the inner preform is inserted into the outer preform. At least one preform may have ribs extending radially towards the other preform. The ribs provided concentricity and interference to hold the preforms together during subsequent operations. The preforms may later be blow molded to provide a bag in bottle or similar container.

The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

A method and apparatus of making an aerosol container. A polymeric container may be provided. The container may have a closed end bottom and a neck longitudinally opposed to the closed end bottom. The container has an internal container volume. A valve and a bag may be provided and a portion of the valve and the bag may be disposed within the container. The bag has a first bag volume. A portion of the at least one of the neck and the bag may contact a portion of the valve to form a temporary seal. Propellant may be introduced into the container. The bag may be collapsed from the first bag volume to a second bag volume. The pressure of the propellant and the pressure within the bag equilibrate. The valve may be joined to the container and the propellant may be sealed within the container.

A container for dispensing pressurized fluid, such as an aerosol. The container includes a plastic bottle having a top portion, tapered neck, main body and a bottom. The top portion and tapered neck are covered by an adapter collar for providing a safety cover. The adapter collar can further have a valve assembly for dispensing the fluid contained in the bottle. A based cover can be further provided to cover the bottom of the bottle. The bottle, adapter collar and base cover can be covered and secured together, in part, by a sleeve such as a heat shrink sleeve.

An aerosol dispenser, an outer container for an aerosol dispenser, and a preform for an outer container. The aerosol dispenser, outer container, and preform each have a neck including a crimp ring. The crimp ring may be configured to receive a valve cup, which is clinched thereto. The crimp ring includes one or more vents. The vents may be used to control overpressurization within the dispenser. The vents may be exposed to pressurized propellant and product due to deformation of the neck during undue overpressurization. The vents allow propellant and/or product to be released therethrough in the event of overpressurization.
