Definitions
- This invention relates to dispensing devices and more particularly to a combination of a dispensing device and a disposable mixing device employing stationary mixing elements for use therewith. Still more particularly, it relates to the combination of a dispensing device and a disposable mixer with means for both preserving the integrity of and preventing contamination between two or more fluids being dispensed, and for maximizing the mixing of the fluids with a minimum of pressure drop along the axis of the mixing device.
- Dispensing devices of this general type are useful in the application of a variety of pasty or highly viscous products such as adhesives, joint filler agents, foams, sealants, molding compounds etc., whereas the products consist of two or more components to be stored separately, before use to be mixed however in order to start a chemical reaction between them, usually causing a solidification or hardening of the mass.
- the content of the cartridge is pressed out of each barrel by actuation of a delivery plunger, the components flowing from the orifice into and through the attached mixer unit where they become closely intermixed.
- the content of a cartridge is dispensed intermittently in several portions, whereas the components joined within the mixer will steadily react during the idle intervals.
- the mixer will become inoperable and will have to be replaced. This is due to the fact that the components will cure at the interface between the cartridge and the mixer and, due to diffusion, this curing will extend back in to the cartridge. This may hinder the detachment of the mixer (ordinarily left on the cartridge), but even worse, solidified particles or "clods" formed in the mass will block the further dispensing of the cartridge content and will cause defective application, such as rippled surface on articles, faulty joints, etc.
- Dispersing and mixing combinations have been known in which fluids to be mixed have been dispensed by double barrelled syringe or caulking gun type dispensers (see e.g. U.S. Pat. Nos. . .3,309,814, 4,041,463.!. .Iadd.3,390,814, 4,014,463.Iaddend., and 4,538,920). These prior devices are included among those described above and have several specific drawbacks.
- the '814 patent employs a moving mixing element and it leaves the two fluids to be mixed in close juxtaposition at the delivery point of the syringe, and hence subject to cross-contamination.
- the mixer was not conveniently disposable, and leaves the orifice of the dispenser subject to contamination by admixture of the two fluids.
- the '463 patent discloses a disposable mixing device for use with a two barrelled dispenser and a baffle which extends into the mixer. Contamination between the two fluids at the orifice of the dispenser is avoided by a rubber seal.
- the '920 patent discloses a disposable mixing tube secured to a double barrelled syringe type dispenser in which a premix chamber is used to split each of the separate streams prior to their reaching the mixing elements.
- the disadvantages of this type of premixing are that it introduces a substantial pressure drop in the mixing line and does not cooperatively contribute to the mixing action of the stationary mixing elements further downstream.
- the objects of this invention are to overcome some or all of the disadvantages of the prior art. More particularly, it is an object to provide a dispenser and disposable mixer combination in which cross-contamination between a plurality of fluids is avoided at the orifice end of a multibarrelled dispenser without substantial pressure loss. Still another object is to accomplish the foregoing objectives and at the same time direct the moving streams in such a way as to enhance the mixing action of the stationary mixing elements downstream.
- a two-component dispensing device comprising a twin-barreled dispensing cartridge, with two dispensing channels separate by a partition wall and each of the barrels leading into a common orifice in which a baffle separates the two streams and terminates at its downstream end with a transverse radially extending end, and further comprising a static mixer unit releasably attached to said orifice, said mixer unit having a plurality of mixing vanes stacked in succession with alternating right-hand and left-hand twist and fixed in alternately offset rotary position within a mixing tube.
- a feature of the invention is that a ribbon-like separating element is used in the mixing tube with its upstream end in abuttment with the downstream end of the orifice baffle and its downstream end in abuttment and at right angles to the next mixing element downstream.
- connection between the mixing tube is arranged so that when it is fully connected to the dispenser there is a substantial residual spring compression between the separation element and the end of the baffle.
- Still another feature is that the separating means is arranged to direct the fluids in a helical path, and the mixing element next downstream is arranged at right angles to the separation means and to reverse the direction of the helical path to maximize the mixing action between the separation element and the mixer.
- FIG. 1 is a side view of a two-component dispensing device. consisting of a twin-barrelled dispensing cartridge and a static mixer unit, shown partly in section;
- FIG. 2 is a view of the cartridge of FIG. 1 as seen from the side of the orifice;
- FIG. 3 is an inlet end view of the mixer unit of FIG. 1.
- FIG. 4a is a view of a cartridge end for three fluids.
- FIG. 4b is a view of the inlet end of a mixer for three fluids. .Iaddend.
- the illustrative embodiment of the invention herein described comprises a dispensing device 1 shown in FIG. 1 employing two cylindrical parallel barrels 2, each having a delivery plunger or piston 3 for the delivery of the cartridge contents.
- a dispensing channel 5 communicates with a common orifice 6 of the cartridge, the two channels being separated up to and within the orifice by a baffle 4 the downstream end of whichis in the form of a line extending radially across the orifice 6 which is surrounded by a base plate 7 for detachably and fittingly mounting a static mixer unit 10 comprising a mixing tube 11 to the orifice.
- Said base plate 7 is provided with two juxtapositioned claws 8 for mounting the mixer unit 10 in the manner of a bayonet or quarter-turn fastener.
- the flange is put against the socket plate 7 between the claws 8 in a rotary position 90° offset from that in FIG. 3, and then rotated by a quarter turn whereby the flange grips under the claws 8.
- the static mixer unit 10 Within the tube 11 of the static mixer unit 10 are stacked longitudinally in succession, as known per se, a plurality of stationary mixing vanes 14, 16 with alternating right-hand and left-hand twist and fixed in the tube alternately at right angles.
- all of the mixing elements 14, 16 are preferably formed in a single molding so as to form a mixing element assembly and they are fixed as a single unit in the tube 1. A subdivision into two or more sectional elements is, however, possible.
- the first element 14 can be a ribbon-like separator having a transverse, radially disposed end corresponding to that of the downstream end of the baffle 4. Whatever its form is, it is placed in the inlet end of the tube 11, with its upstream end in tight . .abuttment.!. .Iadd.abutment .Iaddend.with the end of the baffle 4.
- This separator 14 may be contoured as one of the mixing elements, or it can merely serve to maintain the integrity and separation of the two streams with varying degrees of twist to flat.
- the first element 14 i.e. the separation means
- the first element 14 of the mixer unit be fixed relative to the mixing tube 11 such that its inlet edge 15, after connecting the mixer unit 10 to the twin cartridge 1, as described before, is oriented parallel to and in . .abuttment.!. .Iadd.abutment .Iaddend.with the downstream end of baffle 4 in the orifice.
- the separation means 14 continues a substantial distance into the mixing tube 11 beyond the interface 20 (delivery point) between the end of the orifice and the first point at which the two, usually reactive, fluids actually contact each other.
- This distance is selected to ensure that, even during lengthy idle periods after dispensing has begun, no reaction or hardening of the cartridge content can occur either at the delivery point 20 of the orifice or by diffusion back into the cartridge.
- substantially distance is intended to mean such a dimension.
- the necessary relative position of the separator 14 (and, consequently, of the following vanes 16) within the mixing tube 11 may be achieved preferably by means of a tight fit, i.e. by matching the diameters of the vanes and the bore of the tube.
- the separator 14 is somewhat extended at its inlet edge 15 in the direction of the tube diameter, the extensions resting in corresponding notches 17 provided in the tube wall (FIG. 3).
- axial pressure is provided between the inlet edge 15 and the downstream end of baffle 4 to ensure tight connection.
- the inlet end 15 may preferably be formed with a bevel.
- the elements 14, 16 are formed, as usual, as as a single piece including both right and left mixing elements (of molded plastic), it is possible to fix the mixing elements as a united assembly in the tube 11 at its exit end 18 axially and in rotary position with respect to the tube 11 (e.g. as known per se, by means of cam-like guides at the innerside of the tube) in order to ensure the correct connection of the inlet edge 15; by suitably dimensioning of the lengths of the mixing element assembly and the tube, . .in that case,.!. the inlet edge 15 may be urged with residual spring compression against the end of baffle 4 by slightly compressing the mixing element assembly axially when joining the mixer unit 10 with the cartridge 1.
