Definitions
- the invention relates to a coaxial cartridge set comprising a plurality of coaxial cartridges, each of which is designed to receive and store a first and a second component of a flowable two-component mass in separate coaxial chambers and to be placed in a support structure for squeezing the mass out of the cartridge.
- Various cartridge designs are known for receiving two components of free-flowing masses in separate chambers, which can be dispensed using a dispensing device.
- a dispensing device With regard to the arrangement of the chambers, a distinction is made between coaxial cartridges and cartridges or foil packs with individual cartridges or foil bags arranged next to one another for the various components of a two-component mass.
- the two-component mass can be, for example, a sealing or fastening mass such as mortar, adhesive and much more.
- suitable support structures for the cartridges, into which the cartridges are inserted for the squeezing process are to be used in most cases. These support structures absorb the pressure of the cartridges during the squeezing process and prevent the cartridges from expanding, which are mostly made of plastic and would therefore yield to a high pressure during the squeezing process without the support structure.
- a support structure is to be used here as well, which reduces deformation of the outer wall of the cartridge during the squeezing process to a minimum.
- the support structure must be as close as possible to the against the outer wall of the cartridge and be as stable as possible in relation to the pressure differences prevailing during the squeezing process.
- the object of the present invention is to provide a set of coaxial cartridges which are each designed to store a free-flowing two-component mass in different mixing ratios and to be placed in a support structure for pressing the mass out of the cartridge, as far as possible without the described disruptive pumping behavior based on restoring forces.
- a coaxial cartridge set includes a plurality of coaxial cartridges.
- Each of these coaxial cartridges is designed to receive and store a flowable two-component mass and to be placed in a support structure for extruding the mass from the cartridge and comprises a hollow cylindrical inner chamber for receiving a first component of the two-component mass and a coaxial (ie with the same cylinder axis) around it arranged hollow-cylindrical outer chamber for receiving a second component of the two-component mass.
- the inner chamber and the outer chamber are closed on one of the two end faces of the cartridge at which the mass is discharged from the cartridge (referred to herein as the “front end”), except for one discharge opening per chamber.
- each cartridge includes an inner piston which closes the inner chamber at the rear (ie towards the other end face of the cartridge) and can be moved axially therein, and an outer piston which closes the outer chamber at the rear and can be moved axially therein.
- the two-component mass thus comprises a first component and a second component, which are stored separately from one another in the cartridge and are only mixed with one another when they are dispensed from the cartridge.
- This can in particular be a sealing or fastening compound such as mortar, adhesive and the like.
- All cartridges in the set have an identical external geometry in the area intended for insertion into a support structure and for holding therein, which covers, for example, the entire cylindrical outer wall of the outer chamber and that part of the front face that does not cover the discharge openings or a mixer connection piece ( see. 1 ), may include. In this way, all cartridges can be used with one and the same support structure.
- Two or more cartridges of the set are designed for different mixing ratios of the two components, in that their inner chambers are of different sizes in (radial) cross section.
- the cross-section of coaxial cartridges is always referred to herein as the radial cross-section, i.e. a cross-section perpendicular to the cylinder axis of a cartridge.
- the outer chambers of all cartridges are of the same size on the outside and, with differently dimensioned inner chambers, have a correspondingly differently sized annular cross section.
- the two pistons - the inner piston and the outer piston - are dimensioned in each cartridge according to the cross-sectional dimensions of the inner and outer chambers in such a way that the piston can be axially displaced in its chamber and the mass can ideally be completely pressed out of this chamber through the discharge opening.
- the mixing ratio of a coaxial cartridge can be defined here, for example, by a cross-sectional ratio of the inner and outer chambers, not counting the respective wall thicknesses.
- One idea of the invention is therefore the creation of a set of coaxial cartridges, which are characterized in that with a mixing ratio that varies from cartridge to cartridge, only the diameter of the inner tube (which radially delimits the inner chamber) is varied. The outer diameter of the outer chamber - and thus of the entire cartridge - remains unchanged.
- the same high quality of the squeezing process can be guaranteed, in particular without the disruptive pumping behavior of the type mentioned at the outset.
- the hollow-cylindrical inner chamber of each cartridge of the set has a circular cross-section and the hollow-cylindrical outer chamber has a circular cross-section.
- all the cartridges in the set have the same outside diameter, with those cartridges which are designed for different mixing ratios differing in the different diameters of their inner chambers.
- a circular cross-section is not absolutely necessary for the functionality described herein, so that other cross-sectional geometries, such as oval or rectangular, can also be implemented.
- the coaxial cartridges of the set can in particular be made at least partially from plastic.
- the entire cartridge can be made of plastic, with its individual components being made of the same or different types of plastic, depending on better suitability. In principle, however, other materials, such as metal, can also be used.
- the cartridges in the kit may each be one-piece, i. H. in one continuous piece.
- production by injection molding from plastic can be suitable for this.
- the movable pistons can also be manufactured separately.
- an area ratio of the discharge openings of the inner and outer chambers is approximately equal to an area ratio of the cross sections of the inner and outer chambers.
- the coaxial cartridge set comprises several cartridges with different mixing ratios of between 1:1 and 10:1 for the second and the first component of the two-component mass.
- the coaxial cartridge set can have at least two cartridges with different mixing ratios of 1:1, 2:1, 3:1, 5:1, 7:1 and/or 10:1.
- this is not limiting.
- other mixing ratios which are fundamentally arbitrary, can also be realized in the manner described herein.
- each cartridge has a connecting piece on the side facing away from the inner and outer chambers, into which both the discharge opening of the inner chamber and the discharge opening of the outer chamber open and which is used to connect a mixer for mixing the first and the second component of the two-component mass is formed during the squeezing process.
- a connecting piece on the side facing away from the inner and outer chambers, into which both the discharge opening of the inner chamber and the discharge opening of the outer chamber open and which is used to connect a mixer for mixing the first and the second component of the two-component mass is formed during the squeezing process.
- a system for storing and dispensing a flowable two-component mass comprises on the one hand a coaxial cartridge set of the type presented here and on the other hand a support structure with a receptacle that is at least partially cylindrical on the inside, the shape and size of which are dimensioned for inserting and holding each individual cartridge for squeezing the two-component mass out of it.
- the inside shape and size of the receptacle of the support structure can essentially correspond to the mutually identical external geometry of the coaxial cartridges, so that for example only a minimal cylindrical annular gap remains between them, which is unavoidable for insertion and removal.
- the system also includes the mixer already mentioned above, which is designed to be connected to a connecting piece on the front face of the respective cartridge and to mix the first and the second component of the two-component mass during the squeezing process.
- FIG 1 shows in a schematic longitudinal section an example of a system 1 of the type presented herein, wherein in 1 only one of several coaxial cartridges 2 of the coaxial cartridge set is shown, which is inserted into a hollow-cylindrical receptacle of a support structure 3 for squeezing out the two-component mass contained therein.
- the cartridge 2 is off 1 in two different views without the support structure 3 can be seen.
- Figures 3a and 3b show corresponding views of another coaxial cartridge 20 of the system 1, which is designed for a different mixing ratio than the cartridge 2, but with the same support structure 3 as in FIG 1 is usable.
- the coaxial cartridges 2 and 20 are made of plastic. In order to simplify the manufacture of these cartridges, they can be manufactured in one piece, as can be seen in the figures, with the exception of the movable pistons. The same can also apply to the support structure 3 .
- Figure 2a shows cartridge 2 1 without the support structure 3 in one of 1 corresponding longitudinal section.
- the cartridge 2 comprises a hollow-cylindrical inner wall 4 and a hollow-cylindrical outer wall 5 arranged around it with a common cylinder axis A and in this example a circular cross-section (cf. Figure 2b ).
- an inner chamber 6 delimited radially by the inner wall 4 and an outer chamber 7 arranged radially between the inner wall 4 and the outer wall 5 are formed.
- a first component of the two-component mass to be dispensed is accommodated in the inner chamber 6
- a second component of the two-component mass is accommodated in the outer chamber 7 .
- the longitudinal section of Figure 2a is along the cylinder axis A and the (radial) cross-section of the Figure 2b taken perpendicular to the cylinder axis A of the cartridge 2.
- the cartridge 2 has a front face 8 provided for dispensing the two-component mass. This closes the inner chamber 6 and the outer chamber 7 forward in the axial direction, but has a discharge opening 9 for the first component in the area of the inner chamber 6 and a discharge opening 10 for the second component in the area of the outer chamber 7 .
- the two dispensing openings 9 and 10 open into a connecting piece 11. This is in the front face 8 on the outside of the inner and outer chambers 6, 7 for connecting (e.g. by putting on or screwing on) a mixer (not shown). designed for mixing the first and the second component of the two-component mass during the squeezing process.
- the cartridge 2 also includes an inner piston 12 that closes the rear of the inner chamber 6 and can be moved axially therein, and an outer piston 13 that closes the rear of the outer chamber 7 and can be moved axially therein 1 To the right, the two-component mass can be pressed out of the cartridge 2 through the dispensing openings 9 and 10 and the connecting piece 11 .
- Figure 2b shows a plan view of the front face 8 of the cartridge 2 according to FIG Figure 2a from outside the cartridge 2, ie with a view of its connecting piece 11.
- the cartridge 2 can be designed for a mixing ratio of 5:1 of the second component that can be accommodated in the outer chamber 7 to the first component that can be accommodated in the inner chamber 6.
- the mixing ratio corresponds to a cross-sectional ratio of the outer chamber 7 to the inner chamber 6.
- Figures 3a and 3b show in views accordingly Figures 2a and 2b an example of another cartridge 20 of the system 1 of 1 with one of the cartridge 2 the Figures 2a-2b different mixing ratio of e.g. 3:1. Incidentally, this applies to the Figures 2a and 2b as stated above.
- the connecting piece 11 with the dispensing openings 9 and 10 is also displaced radially in a corresponding manner in order to enable both masses to flow out.
- an area ratio of the discharge openings 9 and 10 according to the cross-sectional ratio of the two tubes (ie chambers 6 and 7) is advantageous in order to achieve an approximation of the discharge speed of both masses.
