Abstract:
The present invention provides a manually rechargeable and reusable aerosol can system and method for refilling an aerosol can, the system comprising a container, a trigger mechanism, an air compressing mechanism and an interfacing mechanism. In one embodiment, the air compressing mechanism is a vane compressor.
Abstract:
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, which in turn has a crimp ring, to receive a valve cup clinched thereto. The crimp ring has slots which act as vents therethrough. The vents may be exposed to pressurized propellant and product due to deformation of the neck during undue internal pressurization. The cross section of the vents diverge in the downward direction to provide both flow area and for product and propellant and adequate area for the valve cup to be corrugatedly clinched to the crimp ring.
Abstract:
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, which in turn has a crimp ring, to receive a valve cup clinched thereto and a lower neck potion upon which the crimp ring is mounted. The lower neck portion extends between the bottom of the crimp ring and a shoulder which transitions into the sidewalls. The crimp ring preferably has a greater axial length than the lower neck portion. This geometry allows flexibility in the thickness throughout the thickness of the entire neck. The geometry advantageously minimizes distortion of the neck in the event of overpressurization.
Abstract:
A fluid dispensing apparatus may be used to dispense a paint fluid from a paint container that is under pressure and that has a pierceable membrane. The fluid dispensing apparatus may include a valve body having a bore, an adaptor having a bore and a piercing member, and a nozzle having a bore. The fluid dispensing apparatus may be operable to pierce the pierceable membrane to communicate the paint within the paint container with the adaptor bore and with the valve body bore. The nozzle may be operable to permit the paint to flow under the pressure out of the paint container, through the adaptor bore, through the valve body bore and through the nozzle bore to ambient.
Abstract:
A pressure relief device for venting an internally pressurized container and an aerosol can having a can bottom containing this pressure relief device. The pressure release device includes a coined pressure vent within a domed can bottom. The pressure vent is characterized by a venting pressure greater than about 500 psig. In addition, the can bottom resists eversion and/or failure along the mechanical attachment to the container body at all pressures between the venting pressure and the longitudinal rupture pressure in the container body.
Abstract:
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.
Abstract:
A refillable spray dispenser comprising a top compartment (6120) and a bottom compartment (6130) separated by a roof (6140); an exhaust hole in the bottom compartment (6130) and a passage extending from the exhaust hole to the bottom opening, and an upper sealing ring. A valve comprising a valve body and a valve core piston (6270), wherein: the core piston (6270) has a stem (6271) firmly inside the valve body and a head (6274) outside the valve body, and a valve groove extends along a portion of the stem (6271) that is inside the valve body; the upper sealing ring (6252) blocking the exhaust hole when the valve is at rest. Pushing a bottom sealing ring (6256) allows the bottom sealing ring (6256) and the valve to be moved toward the roof (6140), fluid to pass through the valve groove and the head groove into the top compartment (6120).
Abstract:
A self chilling beverage container including a heat exchange unit having a pressurized medium therein secured internally thereof and including an over-pressure relief valve. The valve includes a hollow housing within which there is first and second valves. The first valve is operable to inject and release the pressurized medium into the container. The second valve is normally closed and is continuously exposed to the pressurized medium and in response to the pressure thereof reaching a predetermined level opens to exhaust the pressurized medium to the atmosphere to relieve the excess pressure.
Abstract:
The invention relates to a measuring cap (1) for a pressurised container (2), comprising: a body (8) having an axial fluid channel (12), shaped in order to be inserted into the container (2) through the neck (5); a sealing joint (15) shaped bear on a portion of the body (8); an assembly ring (16) which is used for removably securing the measuring cap (1) to the container (2) and which is removable; and a closure member (17) for selectively closing and opening the fluid outlet channel (12).
Abstract:
The invention relates to a container (1), in particular for aerosols, with a container body (2) which comprises an expulsion opening (4) and a discharge opening (6), an expulsion valve (8) which is provided in the expulsion opening (4), and a discharge device (10) which is provided in the discharge opening (6). The container according to the invention is characterized in that the discharge device (10) comprises a first (12) and a second (14) element, wherein at least the second element (14) has at least one through-opening (16), and wherein, by displacing and/or rotating the second element (14) in relation to the first element (12) and/or the container body (2), the through-opening (16) can be brought into a discharge position in which the through-opening (16) connects the interior of the container body (2) to the outside of the container body.
