Definitions

  • the invention relates to a two-component cartridge for two separate plastic masses with a cartridge tube having at one end a front end wall and an integrally formed thereon, arranged centrally to the cartridge tube mouthpiece, which forms an outlet channel, which communicates with the cartridge interior, has, and with an inner tube arranged in the cartridge interior of the cartridge tube, the longitudinal axis of which runs coaxially with the longitudinal axis of the cartridge tube and which at its front end merges into a tubular outlet tube which extends into the outlet channel and communicates with the interior of the inner tube.
  • tubular film cartridge Various types of such two-component cartridges are already known. This includes, for example, the so-called tubular film cartridge.
  • the case used tubular film has two separate chambers, each filled with only one component. This tubular film is compressed when the standard gun is actuated. The two components are pressed out of the cartridge.
  • a disadvantage of this system is the effort that must be operated to fill the 2-chamber tubular film with the two components and thus produce.
  • Coaxial cartridges which are composed of a cylindrical outer tube and a cylindrical inner tube located therein, so that two separate chambers in a coaxial "tube-in-tube" arrangement are present.
  • the bounded by the inner tube chamber serves to receive a component, while the chamber formed between the inner tube and the outer tube for receiving the other component is used.
  • Both chambers or tubes are each closed with a specially adapted piston.
  • a coaxial cartridge with a central, central mouthpiece or outlet is from the DE 199 19 748 A1 known.
  • This cartridge is made up of two plug-in tube parts, wherein these two tube parts are connected by latching in the cartridge neck area.
  • the mass in the inner tube is extruded together as a strand together with the other mass, which is located in the outer tube.
  • the central strand of the inner tube is completely surrounded by the annular emerging other component or mass from the outer tube and is thus embedded as an internal strand in the other component.
  • Object of the present invention is to provide a two-component cartridge in the form of a coaxial cartridge, which is simple and thus inexpensive to produce and leads to a better mixing result.
  • the cartridge tube has at one end a front end wall.
  • a mouthpiece arranged centrally with respect to the cartridge tube is formed, which forms an outlet channel for one of the masses stored in the cartridge and communicates with the interior of the cartridge, so that the mass located in the interior of the cartridge can exit from this outlet channel.
  • the two-component cartridge according to the invention is equipped with an inner tube arranged in the cartridge interior of the cartridge tube, whose longitudinal axis is coaxial with the longitudinal axis of the cartridge tube and thus coincides with it.
  • the inner tube merges into a tubular outlet port which extends into the outlet channel, which communicates with the interior of the inner tube. The mass located in the inner tube can thus be squeezed out via the outlet connection.
  • the inner tube is closed to its open end, after it has been filled with a mass, with a piston.
  • a piston also applies to the annular space around the inner tube, which is formed between the inner tube and the wall of the cartridge tube.
  • this piston is an annular piston or a kind of annular disc.
  • Such pistons and also the cooperating extrusion guns are known.
  • Such extrusion guns have an annular disk-shaped pressing piston and a central and centrally arranged pressing piston.
  • the two-component cartridge according to the invention is characterized in that the inner tube is equipped with at least two outlet nozzles extending into the outlet channel and is in communication.
  • the mass located in the inner tube is thus no longer - as was the case in the prior art - pressed out as a central, completely surrounded by the other mass strand. Rather, the originating from the inner tube mass is distributed to at least two outlet and thus discharged in the form of at least two strands of the mouthpiece. As a result, a rough pre-mixing occurs. In addition, the mixing section is shortened so that significantly lower extrusion forces must be used.
  • Another advantage of the two-component cartridge according to the invention is that when inserting the cartridge in the Auspresspistole not due to the central and centric arrangement of the mouthpiece on the insertion position of the cartridge must be respected.
  • the latter advantage is given in particular when the cartridge tube of the two-component cartridge according to the invention represents a hollow cylinder tube.
  • the two-component cartridge according to the invention is manufactured in one piece and in particular injection molded in one piece, for example of a suitable plastic material.
  • the inner tube is preferably provided at its front end with at least one web which serves for fastening and holding the inner tube.
  • This web preferably extends from the front end of the inner tube to the opposite front end wall of the cartridge tube and extends in the longitudinal direction. This ensures that the mass which is located in the annular space surrounding the inner tube can pass from radially outward to radially inward in the upper region of the cartridge tube and also into those regions within the outlet channel which are not filled by the outlet nozzles or be taken.
  • the arrangement of the outlet nozzle within the outlet channel may be arbitrary in the two-component cartridge according to the invention.
  • the longitudinal axis of the outlet nozzle extends axially parallel to the longitudinal axis of the outlet channel, wherein in turn preferably the longitudinal axis of at least one of the outlet pipe extends laterally offset parallel thereto.
  • one of the outlet nozzle run centrally in the middle, while another is arranged radially outside in the outlet channel.
  • the outlet ports are spaced as far as possible from each other. This is the case, for example, when the outer circumferential surface of the outlet nozzle rests against or coincides with the inner lateral surface of the outlet channel.
  • the outlet connections should furthermore preferably be arranged uniformly distributed in the outlet channel. For example, are two Outlets available, then they should be on the diameter of the outlet channel. If there are three outlet ports, which is preferred, then they form an equilateral triangle in view of the outlet channel or the mouthpiece. In this way, the outlet are as far away from each other, so that the above-described coarse pre-mixing is optimal.
  • the outlet can have any outer and / or inner cross section, for example, polygonal, in particular four, five or hexagonal, or round, have.
  • the outlet ports are cylindrical tubes.
  • the above-mentioned webs are preferably formed as ribs on the outlet.
  • One or more of the outlet ports may terminate or extend beyond or in the plane defined by the end of the mouthpiece or outlet port.
  • all the outlet ports and the outlet channel open in the same plane, which is formed by the end of the outlet channel.
  • FIG. 1 shown in side view two-component cartridge 1 (hereinafter also referred to only as a cartridge) has a cylinder tube-shaped cartridge tube 2, which is closed at one end by a front side wall 3. Formed on it is a centric mouthpiece 4, which forms an outlet channel 9 and externally has a thread 17 to which a corresponding thread of a cap, not shown, can be screwed to seal the outlet channel 9 to the outside. If the cartridge 1 according to the invention is used, then a nozzle with a static spiral mixer can be screwed onto the thread 17. Such a spiral mixer is shown for example in German Utility Model G 94 05 922.5.
  • the cartridge is open at its opposite end of the mouthpiece 4 and can be closed with suitable pistons, which will be discussed in more detail below.
  • the longitudinal axis 6 coincides with the longitudinal axis 6 'of the cartridge tube 2 and also the longitudinal axis 6 "of the mouthpiece 4 and der Auslasskanals 9.
  • the inner tube 7 has at its front end 12 an end wall 15 which has three holes, which are divided into three separate, Altogether there are thus three outlet ports 5, 5 'and 5 ", as is also the case with the exhaust ports 5, 5' and 5" FIGS. 4 to 6 evident.
  • the outlet ports 5, 5 'and 5 represent cylinder tubes, via which a mass 10 (not shown) located inside the inner tube 7 is pressed out of this inner tube 7 when acted upon by a piston, not shown, at the free end of the inner tube 7.
  • the outlet ports 5, 5 ', 5 are arranged radially outside in the outlet channel 9 and uniformly distributed therein, so that the radially outer outer circumferential surface of these outlet 5, 5', 5" with the inner circumferential surface 16 (see. FIG. 4 which shows a top view of the cartridge 1 according to the invention) of the outlet channel 9 coincides.
  • the longitudinal axes 14 of the outlet 5, 5 ', 5 lie on the vertices of an isosceles triangle.
  • the inner tube 7 is provided at its front end 12 with three webs 13, which are arranged distributed uniformly on the periphery of the inner tube 7 and extend in the axial direction, see. also FIG. 5 , It can be seen in particular from the last figure that the webs 13 form ribs in the area between the end wall 15 of the inner tube 7 and the end wall 3 of the cartridge tube 2, which extend along the outlet ports 5, 5 ', 5 "and, based on the section, from this outlet port 5, 5 ', 5 “protrude radially outward.
  • the cartridge 1 according to the invention in a known Auspresspistole with an annular disc-shaped plunger for acting on the annular piston, which closes the cartridge interior 8 at the open end and is not shown, and with a central plunger against the central piston for closing the interior 10 of the inner tube. 7 is used and is also not shown in the drawings, used, and pressure is exerted on the annular piston and the central piston, then the in the masses inside the cartridge 8 and the interior 10 of the inner tube 7 are pressed out of the mouthpiece 4.
  • the mass in the cartridge interior 8, which is in itself an annular space is squeezed out through the outlet channel 9, whereas the mass inside the inner tube 7 is pressed out through the three outlet sockets 5, 5 ', 5 ".
