Abstract:
A spray system for formulating an ambient curable clear coat product includes a first container containing a mixture of a polymer with primary hydroxyl functionality and an amino crosslinker with alkoxymethyl functionality and a propellant and a second container containing a catalyst formulated to initiate a polymerization reaction of the polymer and crosslinker when added to the first container. The system also includes a charging device configured to transfer the catalyst from the second container to the first container.
Abstract:
A dispenser (1) includes a container (3) for the storage of a liquid, a gas cartridge receiving portion (5) for holding a gas cartridge (4) so that the contents of the container may be pressurized by gas in a gas cartridge, a dispensing arrangement for dispensing the liquid as a spray. The dispenser includes an activator (13) for moving a gas cartridge so that the gas cartridge is in position to pressurize the container, and an inhibitor (17) which inhibits movement of the dispensing arrangement. The activator is associated with the inhibitor so that movement of the inhibitor from the first to second inhibitor positions causes the activator to move the gas cartridge so that the gas cartridge is in position to pressurize the container.
Abstract:
The invention relates to a pressurized can comprising a body (2), a dome (3) accommodating a valve (4), a concavely shaped bottom (5), an inner casing (7) attached to a cup (6) located in bottom (5), a push rod (9) arranged in the inner casing (7), said push rod (9) being actuated through the cup (6) and intended to force open the inner casing (7), with said inner casing (7) being joined to the cup (6) via a spring cage (11), said spring cage (11) containing a spring-loaded trigger (12) the bottom-side end of which extending through the cup (6) and acting on the push rod (9), said push rod (9) acting on a membrane (8) arranged at the valve-side end of inner casing (7), said membrane at its valve-side end sealing off the inner casing (7) hermetically against the contents of the pressurized can (1) and being forced open by the push rod (9) actuated by means of trigger element (12), with the spring cage (11) being designed so as to be closed off at its valve side and the trigger element (12) being provided at its bottom side with a sealing element (26) acting against the inner wall of the spring cage.
Abstract:
An aerosol system or method for mixing first and second materials comprising first and second container assemblies and a coupler. The first container assembly contains the second material and a propellant material that pressurizes the second material. The second container assembly contains the first material and at least a partial vacuum. The coupler comprises first and second coupler connecting portions and is arranged such that the first coupler connecting portion engages the first container assembly and the second coupler connecting portion engages the second container assembly. The propellant material and the partial vacuum in the second container assembly cause a portion of the propellant material and at least a portion of the second material to flow into the second container assembly to form a mixture in the second container assembly. The propellant material within the second container assembly forces at least a portion of the mixture from the second container assembly.
Abstract:
A cartridge for assembly to the dispensing head of a Bio Cannister M-11 decontamination dispenser for maintaining booster chemicals separated from the liquid decontamination solution until ready for use thus preserving the shelf life of the decontamination system. The cartridge is configured to fit within the canister of the M-11 dispenser when assembled with the dispenser head.
Abstract:
Two-part reactive polymeric coatings are prepared and applied from an integral dispensing system. The reactive components are held in two separate containers held together by a coupling. Each container is sealed by a pierceable membrane. A piercing tube is disposed within the coupling. In use, the containers are twisted together to cause the tube within the coupling to pierce each of the membranes. Breakaway tabs protect against inadvertent displacement of the containers and provides a clear indication of whether the tube has pierced the membranes. Differential pressure between the containers causes the components to mix and begin to react; a net positive pressure with respect to the ambient atmosphere permits the mixed components to be applied as a spray. An externally mounted spray feed tube provides great flexibility in application of the paint being sprayed.
Abstract:
An aerosol dispenser having a transparent container for storing a propellant and a first compound under pressure. An actuator cap normally closes a valve mounted on top of the container to control the dispensing of the materials from the container. An ampule containing a second material separate from the first material until the ampule is broken is positioned generally along the bottom of the container with a saddle shaped foot. A push rod extended through the valve holds the foot in engagement with the ampule and breaks the ampule when the valve is first moved to its open position. The materials are mixed within the container and are dispensed through a filter mounted on a dip tube leading to the valve.
Abstract:
An aerosol dispenser having a transparent container for storing propellant and a first compound under pressure. A normally closed valve is mounted on top of the container to control the dispensing of the materials from the container. An ampule containing a second material separate from the first material until the ampule is broken is positioned generally longitudinally along the length of the container with a sleeve. A push rod connected to the valve and extended through a generally cylindrical filter surrounding the valve has a convex shaped finger and an inclined shoulder that cooperates with a beveled edge of the sleeve to break the ampule when the valve is first moved to an open position. The materials are mixed within the container and move through the filter before entering the valve. The mixed materials and propellant are dispensed through a nozzle of an actuator member mounted on the container when the actuator member is depressed causing the valve to open.

An ampule containing a second material separate from the first material until the ampule is broken is positioned generally longitudinally of the length of the container with a sleeve. A push rod connected to the valve has an inclined shoulder that cooperates with an edge of the sleeve or a ring to break the ampule when the valve is first moved to its open position. The push rod alternatively pivots an angle member pivotally supported on the sleeve to break the ampule. The materials are mixed within the container and are dispensed through a filter mounted on a dip tube leading to the valve.
Abstract:
An additional container (29) for receiving further components is arranged in the container (21) for discharging preferably polyurethane foam. The additional container (29) receives a rod (37) cooperating with an inner cover (45) sealed in said container (29). The rod is led to the outside through a packing (31) in an additional container connection connected to the bottom (20) of container (21) and is movable into container (21) for blowing off cover (45). A disk (24) inserted in a recess of container bottom (20) and fixed by its beaded edge secures a sleeve (31) penetrated by the rod (37) constructed as an axially movable plunger. The outer and inner edges (39, 40) of sleeve (31) bring about a sealing action on in each case one radial collar (38, 39) of the plunger when rod (37) is inserted, and resiliently gives way during the axial movement of the plunger.
