Definitions

  • Two-component cartridges for plastic compositions such as sealants, adhesives, dental molding compounds or other materials are known. They have two chambers, which are often arranged coaxially and often formed by two nested coaxial tubular body, which are nested with their mouthpiece areas.
  • a first chamber is formed by the interior of the inner tubular body and a second chamber is formed as an annular chamber between the outer and the inner tubular body.
  • the two tubular bodies are held in their coaxial position by the annular piston closing the outer annular chamber.
  • the nested mouthpieces of the two tubular bodies form outlets for the material components in the inner first chamber and the outer second chamber, respectively.
  • the two-chamber cartridge is closed by a cap, with which it is resealable even when work is interrupted.
  • a mixer is screwed onto the mouthpiece neck of the outer tubular body, which has a mixing tube in which a number of Mischkörpem is housed axially behind each other to the emerging from the first chamber first material component with the exiting from the second chamber material component as fast as possible to mix homogeneously. At the end of the mixing tube then a completely homogeneous mixture of the two material components should emerge.
  • the one problem is to ensure that the two components of the material are completely separate from each other before the two-component cartridge is broken and can not come into contact with one another to prevent premature reaction of the two components with each other and their setting or curing.
  • the cap on the one hand, the mouthpiece assembly of the two tubular body as a whole closes absolutely tight, and that the cap also makes a completely sealing separation of the outlets from the first chamber and the second chamber.
  • the second problem is the design of the mixing system such that a homogeneous mixing of the two material components with as few mixing elements containing the shortest possible mixing tube is made possible, because the necessary extrusion pressure of the two-component cartridge, of course, the greater, the greater the number of axially successive mixing elements in Mixing tube is, because every other mixing element increases the flow resistance. This problem is all the more significant the more viscous the material components to be squeezed out and mixed are.
  • the mouthpiece portion of the inner tube body which is inserted into the mouthpiece portion of the outer tube body, formed with a coronary arrangement of separate segmental or cylindrical outlet channels which sit like a star in the mouthpiece part of the outer tubular body, wherein the circumferential spaces between the individual outlet channels of the mouthpiece part of the inner Pipe body, which form the outlet channels for the first material component, forming the outlet channels for the second material component.
  • the material strands of the first material component and the second material component which alternate in the circumferential direction then enter into the inlet end of the mixer as a parallel strand bundle.
  • the object of the invention is to provide an arrangement which brings a significant improvement in this problem.
  • closure cap must individually close each of the outlet channels of the mouthpiece portion of the inner tube body and to have an engaging in the respective outlet channel and tightly closing pin must have.
  • the tightness is difficult to achieve even with a wreath of cylindrical pin for cylindrical outlet channels, and still significantly more difficult to achieve in cross-sectionally annular outlet channels.
  • the closure cap must be formed in two parts and have an inner plug part, on which the locking channels engaging in the outlet channels are formed, and have a threaded sleeve which is screwed onto the mouthpiece neck of the outer tubular body.
  • the invention should be able to remedy this further problem in a further embodiment.
  • the arrangement according to the invention consists essentially in that a single, approximately cylindrical outlet channel of the mouthpiece part of the inner tubular body extends only at its outlet end in the form of a coronary arrangement of several outwardly diverging pocket-like extensions in the light cross section of the annular to this outlet channel for the first Material component extending outlet channel for the second material component in the mouthpiece part of the outer tube body.
  • the central region of the mouthpiece part associated with the inner tubular body in the region of its outlet cross section is assigned a baffle plate which covers the central region approximately over a surface area corresponding to the cross sectional area of the cylindrical outlet channel, so that the material of the first material component emerging from the interior of the first tubular body is forced. past the baffle plate radially outward into the pocket-like extensions of the outlet channel, thereby forming a plurality of strands of material exiting the pocket-like extensions with an axial component and a radially outwardly diverging directional component.
  • the baffle plate is formed by a central body associated with the mixer and disposed at the inlet end in front of the first mixing element, which may be knob-shaped and is preferably formed with a deflecting tip pointing counter to the material flow direction, and the mixer the mouthpiece assembly is placed, projects into the outlet end of the outlet channel for the first material component from the interior of the first tubular body.
  • the cap can be made very simple. It only needs to have a central pin, which projects into the cylindrical outlet channel of the mouthpiece part of the inner tubular body and a forms this occluding stopper. Thus, a reliable seal can be achieved very easily.
  • the baffle plate is integrally formed with the mouthpiece part and connected by means of the inner wall of this outlet channel outgoing, rib-like or web-like or similarly formed support elements with the mouthpiece part.
  • the connecting elements are advantageously so far upstream connected to the inner wall of the cylindrical outlet channel, that downstream still a sufficiently long axial cylindrical or slightly conical portion of the outlet channel remains, in which a hollow cap formed on the cap can dip, which acts as a plug and on the Baffle plate is pushed.
  • the flowing through the annular outflow between the mouthpiece parts of the inner tube body and the outer tube body second material component is also divided by the flow obstacles, which are formed by the pocket-like extensions of the outlet channel of the first material component in several strands of material alternately in the circumferential direction with those through the pocket-like expansions emerging material strands of the first material component are arranged.
  • the second material component experiences a respective lateral flow deflection, which is why the material strands of the second material component are affixed with circumferential direction components, thereby immediately mixing with the material strands of the first material component. even before the strands of material reach the first mixing element in the mixing tube of the mixer.
  • the invention thus brings a very significant advantage in terms of the efficiency of mixing the two material components, the number of mixing elements required in the mixing tube, and consequently a very significant reduction of the necessary extrusion pressure, which brings a great advantage especially for viscous masses.
  • the arrangement according to the invention greatly simplifies the design of the closure cap and its sealing safety. Because the inner exit channel for the first material component is cylindrical and centered and only one such channel is present, the closure cap may be integrally formed and have a single central plug which engages the cylindrical portion of the exit channel for the first material component and this is completely sealed closes.
  • the Fig. 1 and 4 show as the first embodiment in each case in axial section the mouthpiece-side end region of a two-component cartridge.
  • the two-component cartridge after the Fig. 1 and 4 consists of an outer tube body 1 with a front end wall 2 and a mouthpiece part 3, which is provided with an external thread 4, and an inner tube body 5 with a mouthpiece part 6.
  • the inner tube body 5 is arranged coaxially in the outer tube body by the mouthpiece part 6 of inner tubular body 5 is inserted into the mouthpiece part 3 of the outer tubular body 1 and locked there.
  • the inner tubular body 5 forms with its inner space 7 a first chamber for receiving a first material component
  • the outer tubular body 1 forms between itself and the inner tube body 5, an annular second chamber 8 for receiving a second material component.
  • the mouthpiece part 6 of the inner tube body 5 forms a cylindrical outlet channel 9 for the first material component
  • the mouthpiece part 3 of the outer tube body 1 forms between it and the mouthpiece part 6 of the inner tube body 5 an annular outlet channel 10 for the second material component.
  • the axially rear, latched in the mouthpiece part 3 of the outer tubular body 1 portion of the mouthpiece part 6 of the inner tubular body 5 has along its circumference a plurality of passageways for connecting the annular second chamber 8 with the annular outlet channel 10, which in the drawing figures 1 and 4 are not visible, because the local section passes through the Verrastungsrippen 11 of the mouthpiece part 6 of the inner tube body 5.
  • Fig. 1 and 4 differ in that in Fig. 1 a mixer 12 is screwed onto the mouthpiece assembly while in Fig. 4 a cap 13 is screwed onto the mouthpiece assembly.
  • the mixer 12 has a mixing tube 14, which is widened at its inlet end to a threaded sleeve 15 which is screwed onto the external thread 4 of the mouthpiece part 3 of the outer tubular body 1, and takes in the mixing tube 14 a number of axially successive, known per se Mixing elements 16, which rotate and divide the strands of material again and again, thus causing the mixing.
  • Fig. 3 shows in perspective view the front end portion of the inner tube body 5 with its mouthpiece part 6.
  • Verrastungsrippen 11 and the circumferentially formed between these passageways 17 are visible in detail, which connect the second chamber 8 with the annular outlet channel 10.
  • the mixer insert 16 consisting of the mixing elements 16 of the mixer 12 has at its lower, ie inlet end a central pin 19 which terminates in a knob-like central body 20 which forms a baffle plate and, when the mixer 12 to the mouthpiece assembly 3, the sixth is placed, protrudes into the outlet end of the inner cylindrical outlet channel 9 and the center region closes, so that the emerging from this outlet channel 9 first material component is divided into four obliquely radially and axially through the pocket-like extensions 18 flowing material strands.
  • the central body 20 preferably has, as shown, an upstream pointing Ablenkspitze 21, which, as shown, may be formed as an approximately cylindrical and rounded pin or conical.
  • the emerging from the annular outlet channel 10 second material component is then also divided by the pocket-like extensions 18 of the outlet channel 9 in several strands of material extending between the strands of material of the first material component and obtained by each taking place in the circumferential direction marflection through the pocket-like extensions 18 a cross-directional component , which favors the immediate mixing with the material strands of the first material component.
  • Fig. 1 This consists of one piece and has on its end wall 22 a molded cylindrical hollow pin 23 whose axial length is dimensioned so that when screwing the cap 13 on the external thread 4 of the mouthpiece part. 3 of the outer tubular body 1 engages in the cylindrical part of the outlet channel 9 of the mouthpiece part 6 of the inner tubular body 5 and sealingly seals it.
  • the baffle plate which is formed by the central body 20 at the inlet end of the mixer end, separately formed by the mouthpiece assembly 3, 6 and comes only by the placement of the mixer with the mouthpiece part 3 in cooperation.
  • Fig. 5 and 6 show a second embodiment of the invention, which differs from the first embodiment in that the baffle plate is formed as part of the mouthpiece part.
  • Fig. 4 and 5 are the same or corresponding elements with the same reference numerals as in the Fig. 1 to 4 provided, and corresponding but modified elements are also provided with the same reference numerals, but with an addition.
  • Fig. 5 shows the mouthpiece side end portion of a two-component cartridge with outer tube body 1 and inner tube body 5 with mounted mixer, while Fig. 6 the end area without patch mixer shows.
  • the outer tubular body 1 with a front end wall 2 and a mouthpiece part 3, which is provided with external thread 4, and the inner tubular body 5 with its mouthpiece part 6 according to the arrangement of the Fig.

  • connection of the webs 19a with the inner wall of the mouthpiece part 6 takes place only at a certain axial distance from the end of the cylindrical portion of the outlet channel 9 upstream offset position and this point is downstream of this joint radially inwardly reset so that a short axial cylindrical end portion 9a of the outlet channel 9 is formed, in which a cylindrical annular sleeve can be immersed on a closure cap and thus can cooperate sealingly.
  • the diameter of the baffle plate 20a is slightly smaller than the light cross section of the cylindrical outlet channel 9, so that such a hollow cylindrical annular projection of a closure cap can slide over the baffle plate 20a and thereby come into cooperation with the end portion 9a of the outlet channel.
  • FIG. 5 and 6 Another possibility of modification of the invention, which is not shown in the drawing, but essentially the embodiment of the Fig. 5 and 6 corresponds, would be a snap connection between the arranged on the inner mouthpiece part 6 baffle plate 20a via correspondingly modified connecting webs 19a and provided in the inner wall of the mouthpiece part 6 counter-elements, for example in the form of a radial gradation.
  • the baffle plate 20a with the connecting webs 19a would then have to be manufactured separately and then inserted and locked. While such an embodiment is basically possible, currently in the Fig. 5 and 6 presented one-piece embodiment favors because it is less expensive to implement manufacturing technology and does not involve the risk that the material pressure on the baffle plate this could be pushed out at possibly incorrect latching.
