Definitions
- the invention relates to a dispensing apparatus for operating double cartridges provided with holding flanges, which has a front face retaining guide with slide-in opening on one side for receiving the holding flange as well as two dispensing plungers, which can be moved out of the front of the apparatus along parallel axes.
- the present invention is based on the task of achieving rigid anchoring, which can be subjected to high stress, between dispensing apparatus and exchangeable cartridges through suitable apparatus design and without increased costs for the cartridges.
- FIG. 1 shows, as first embodiment, a manually operated dispensing apparatus together with a double cartridge (only partially shown) to be slid in laterally;
- FIG. 2 shows a vertical section through the front area of the apparatus along line II--II in FIG. 1;
- FIG. 3 shows, as second embodiment, a dispensing apparatus with pneumatic plunger drive and cartridge insertion from above;
- FIG. 4 is the front view of an additional apparatus variant for cartridges with unequal cylinders, the outline of which is indicated above the apparatus with dot-dash lines.
- the dispensing apparatus 1 serves for the exchangeable reception and operation of double cartridge 10, one of which is partially shown next to the apparatus in FIG. 1 ready to be inserted.
- double cartridges 10 (known per se) have, in general, a rectangular holding flange 11, from which two parallel hollow cylinders 12 extend (shown broken).
- the two cylinders of cartridge 10 serve for separate storage and distribution of two substances generally pasty or viscous, components of a so-called two-component system, which, during dispensing from the cartridge cylinders, are mixed for the purpose of application.
- each cylinder contains a delivery piston (not shown), each of which is intended to be actuated upon by one of two delivery plungers 5 of the apparatus 1 (see also EP-A 0 252 401; U.S. patent application Ser. No. 070,033).
- the dispensing apparatus 1 has an apparatus body 2 to which a holding grip 6 is fixedly connected.
- an actuation lever 7 is articulated, which acts through a mechanism in the interior of the apparatus body 2 (not shown here) upon the two plungers 5.
- the plungers 5 are shown in FIGS. 1 and 2 in their starting position, i.e. inserted in the apparatus body 2.
- a retaining guide 4 is provided on the apparatus front 3.
- the retaining guide 4 has a slide-in opening 9, which is--in the represented apparatus design with plungers 5 arranged side by side--located on a (left or right) lateral edge of the apparatus front 3. Consequently, the slide-in opening 9 extends transversely to a straight line 8, which connects the centers of the two plungers 5.
- the retaining guide 4 is continuous on both sides of the mentioned straight line 8, and at its end opposing the slide-in opening 9, it forms a stop for positioning the holding flange 11.
- the front opening 4a is shaped semi-circularly corresponding to the circumference of a cartridge cylinder 12, with the guide 4 itself ending tangentially to the semi-circle.
- the holding flange 11 of an inserted double cartridge 10 consequently, is held continuously by the retaining guide 4 on the one narrow side as well as on both longitudinal sides; only the second narrow side is free over a distance corresponding to the diameter of a single cartridge cylinder.
- the retaining guide With apparatus of known design, in which the retaining guide has only one longitudinal side, but comprises both narrow sides of the holding flange, the flange by necessity must project on both narrow sides by sections 13 beyond the outer cylinder diameter as is indicated in FIG. 1 in dot-dash lines.
- these sections 13 can be omitted, i.e. the holding flange 11 can end at its two narrow sides tangentially and flush with the cartridge cylinders 12.
- the present design of the retaining guide permits savings of material in the disposable cartridge 10, which is to be produced in large numbers and as inexpensively as possible.
- the present retaining guide can, of course, also be designed for receiving conventional double cartridges with lateral sections 13 projecting on the holding flange.
- the present design of the dispensing apparatus also permits the receipt of individual, i.e. separate cartridge cylinders provided with holding flange in pairs or individually (for one-component systems), which is completely impossible with apparatus according the to prior art.
- the dispensing apparatus 20 is, in a manner known per se, intended to be driven with compressed air.
- the apparatus body is accordingly formed essentially by a cylinder/piston unit 22.
- a compressed air connection 21 is connected below at handle 26 to the apparatus front 23.
- a compressed air control valve (not visible) to be actuated by grip 27 is built into handle 26.
- the two dispensing plungers 25, which can move out of the apparatus front 23 along parallel axes, are connected with the piston (not shown) in the interior of the apparatus body 22 and arranged vertically above one another in the apparatus.
- the slide-in opening 29 of the retaining guide 24 in this plunger arrangement is at the upper edge of the apparatus front 23; it extends again transversely to the straight line 28, which connects the centers of the two plungers 25.
- the retaining guide 24 is continuous on both sides of the straight line 28 and formed in the lower region preferably corresponding to the first embodiment, in that the front recess 24a forms a semi-circle adapted to the circumference of a cartridge cylinder and the guide 24 extends at the lower end tangentially to this semi-circle.
- double cartridges 10 are inserted from above, and, specifically, with vertically extending longitudinal sides of the holding flange 11, i.e. in a position rotated by 90° relative to FIG. 1.
- rigid anchoring of the double cartridges in the retaining guide 24 design possibilities of the retaining guide and of the cartridge holding flange as well as possibilities of inserting independent single cartridges, the description relative to the embodiment according to FIGS. 1 and 2 is applicable.
- a dispensing apparatus 30 can readily be designed along the same principle for receiving and operating double cartridges 10', the two cylinders 12' of which have unequal diameters and the holding flanges 11' of which have, accordingly, the shown outline.
- the front opening 34a is preferably shaped so that, on an inserted cartridge, it is laterally in contact with both cylinders and below is led around the smaller cylinder. Hence, rigid dynamic anchoring of the holding flange is again brought about, which would not be possible according to prior art.
- a holding flange on the double cartridges be unitarily connected with the cartridge cylinders; a loose flange plate (for example made of metal, to be used repeatedly, essentially rectangular) with openings, through which the cylinders can be inserted, would also be conceivable, which then would only be provided with narrow annular flanges for contact on the flange plate.
