Abstract

A dual-compartment cartridge, suitable for storing and dispensing a two-component reactive material which cures when the two different components are mixed, comprises an outer generally cylindrical casing (1) for storing one component and an inner generally coaxial chamber (4) for storing the other component, the inner chamber having a configuration such as to enable it to collapse in the direction of its longitudinal axis when subjected to pressure from one end thereof and having at its other end (6) a frangibly sealable outlet (7) which when unsealed communicates within the outer casing with a means (9, 12, 15) for mixing together the two components within the outer casing, the mixing means communicating with an outlet passage (2) formed at one end of the outer casing (1) and the other end of the outer casing having a disc-like plunger-movable closure means (3), so that when pressure is applied to the closure means, the inner chamber (4) is caused to collapse in an axial direction and thereby force the other component stored therein to flow into the mixing means (9, 12, 15) and be mixed therein with the one component and the resulting mixed material is caused to flow through the outlet passage (2) and be extruded from the outer casing (1). <IMAGE>

Description

COMPARTMENTAL CARTRIDGE This invention relates to a compartmental cartridge suitable for dispensing measured amounts of interreactive materials such as, for example, two component epoxy, silicone, urethane, acrylic, polysulphide, polyester and set-inhibited hydraulic cement systems.
Multi-compartment cartridges, generally dualcompartment cartridges, are widely used in the building and construction industries for storing and dispensing multi-component reactive materials commonly used in those industries as, for example, adhesives, structural fillers, coatings, fillers and the like. One such cartridge is described in U.S. Patent No.4,366,919 in which there is disclosed a cylindrical dual-compartment cartridge having an inner cylindrical chamber surrounded by an outer cylindrical chamber so as to provide an annular cylindrical space therebetween.The inner and outer chambers have separate exit passageways communicating with the neck of the cartridge to which can be fastened a disposable static mixing nozzle having located therein a series of shaped mixing elements which serve to mix together the two inter-reactive materials contained in the cartridge when these are caused to be extruded from the cartridge by application of manual or pneumatic pressure to the disc- and ring-like closure members located at the butt end of the inner and outer chambers respectively.
A disadvantage of such dual-compartment cartridges is that, because of the back pressure exerted by the relatively large number of mixing elements required in the static mixing nozzle, there are limitations in the type and nature of the inter-reactive materials which can be used in such cartridges.
It is an object of the present invention to provide a dual-compartment cartridge which will not require a static mixing device for the extruded reactive materials contained therein and hence will obviate the practical disadvantages resulting from the use of the static mixing nozzles as hereinabove described.
According to the present invention, there is provided a dual-compartment cartridge for storing and dispensing a two-component reactive material which cures when the two different components are mixed, comprising an outer generally cylindrical casing for storing one component and an inner generally coaxial chamber for storing the other component, the inner chamber having a configuration such as to enable it to collapse in the direction of its longitudinal axis when subjected to pressure from one end thereof and having at its other end a frangibly sealable outlet which when unsealed communicates within the outer casing with a means for mixing together the two components within the outer casing, the mixing means communicating with an outlet passage formed at one end of the outer casing and the other end of the outer casing having a disc-like plungermovable closure means, so that when pressure is applied to the closure means, the inner chamber is caused to collapse in an axial direction and thereby force the other component stored therein to flow into said mixing means and be mixed therein with the one component and the resulting mixed material is caused to flow through the outlet passage and be extruded from the outer casing.
Because the mixing of the reactive components is accomplished within the cartridge casing, the use of a static mixing nozzle such as described in U.S. Patent No.4,366,919 can be avoided, a plain smooth sided dispensing nozzle being sufficient for use with the cartridge of the invention. Furthermore, since the inner collapsible chamber can be of a pre-selected size, whilst the outer cylindrical casing can be of a standard commercially available size, the cartridge of the invention can be adapted for use with many different types of inter-reactive materials of varied rheology and viscosity.
In a preferred embodiment of the invention, the mixing means comprises a plurality of concentric baffles.
For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings in which: FIGURE 1 is a schematic longitudinal cross-section of a dual-compartment cartridge in accordance with the invention; FIGURE 2 is a partially cut-away perspective view of the cartridge shown in Figure 1; and FIGURE 3 is an exploded perspective view of the cartridge shown in Figure 1.
Referring to the drawings, a dual-compartment cartridge has an outer cylindrical casing 1 having an outlet neck 2 protruding from one end thereof. A moulded piston 3 is positioned adjacent the closed end of a concertina-like container 4 in which one of the reactive components 5 can be packed. The container 4 is designed to collapse when a pressure is exerted on it in the direction of its longitudinal axis by application of a pressure to the piston 3, for example by means of a pneumatically or manually operable dispense gun (not shown). The open end 6 of the container 4 is temporarily sealed by means of a frangible sealing disc 7 which is designed to break when the piston 3 is operated.The open end 6 of container 4 is force fitted into a neck 8 of a disc-like member 9 having three symmetrically positioned ribs 10, which provide a gap 11 between member 9 and a first baffle member 12 having a first set of concentric mixing baffles 13 which are located so as to be symmetrically offset with respect to a second set of concentric mixing baffles 14 of a second baffle member 15, which abuts the end of the casing 1 having the outlet neck 2. The baffle member 15 is formed with an opening 16 which communicates with the outlet neck 2. The neck 2 is formed with an external helical thread 17 on to which can be fastened a tapered plain (i.e. smooth interior surface) nozzle (not shown) having a corresponding internal helical thread for mating relationship with the neck 2 when the cartridge is required for use.If desired the open end of neck 2 can be sealed with a breakable seal, for example an aluminium foil seal. A second reactive component 18 is packed in the main interior of the cartridge 1.
Various two-component reactive materials may be packaged in the cartridge of the invention. Thus component 18 may be, for example, an epoxy or urethane material, and component 5 a hardener or curing agent therefor. Another example of a two-component reactive material which can be applied by means of the cartridge of the invention is a set-inhibited cementitious composition and a setting agent therefor. The locations of the reactive components may be reversed, e.g.
component 5 may be an epoxy material and component 18 may be the hardener therefor.
The elements from which the cartridge is constructed are formed from suitable organic plastics materials, for example polyethylene, polypropylene, nylon (polyamide), polystyrene or polyacetal material. Thus container 4 may, for example, be constructed from blow-moulded high density polyethylene; piston 3 may be formed from polypropylene; and cartridge casing 1 and members 9, 12 and 15 may be made from high density polypropylene or polyethylene.
In use, operation of piston 3 causes container 4 to gradually collapse in an axial direction towards its end 6 which results in component 5 being forced against and consequently breaking the frangible sealing disc 7 and flowing through the gap 11, from which it is caused to flow, together with component 18, into the mixing means constituted by the concentric baffles 13 and 14. After being mixed by flow through the baffles, the resulting mixture of the components 5 and 18 leaves the cartridge via opening 16 and neck 2 and can be directed to the required location by means of a nozzle fixed to neck 2.
