Definitions

  • the invention relates to a container for storing a multicomponent mass, comprising at least a first container and at least one arranged next to the first container second container for separately stored components of the multicomponent mass and at least one intrinsically stiff head part having a common outlet nozzle and a first attachment portion for one end the first container and a laterally disposed second attachment portion for one end of the second container, wherein the first attachment portion via a first passageway and the second attachment portion via a second passageway is in flow communication with the common outlet nozzle. Furthermore, the invention relates to a separating element.
  • Packages such as foil packs or hard cartridges have proven in the past as packaging for chemical compositions such as mortar, foam, dowel or sealants, which usually consist of several components, which are mixed together only when pressed out of the container.
  • the container is usually inserted into a receptacle of a squeezing device, for example a dispenser.
  • a squeezing device for example a dispenser.
  • the multicomponent mass through a common outlet nozzle on Squeezed head and then passed to mix the Einzelkomponeneten by a screwed onto the outlet nozzle static mixer attachment having a plurality of arranged in its interior mixer elements.
  • a separating element is arranged, which divides the mass flow of at least one container into a plurality of partial streams.
  • Achieving a good mixing effect is particularly necessary if the ratio of the components to be mixed is extremely different, that is, for example, if one component makes up 90% and the other component accounts for 10% of the total mass. With the embodiment according to the invention, good mixing effects can be achieved even with such extreme mixing ratios.
  • Packages in the sense of the invention include both foil packs and hard cartridges.
  • the film bundles comprise at least two foil bags as a container in which the NASA passportde mass is contained.
  • the hard cartridges comprise at least two chambers as containers, which in one embodiment comprise an inner bag containing the mass to be dispensed, contained within the hard plastic chamber.
  • film packs with film bags that are not inherently rigid in the unfilled state are characterized by a less expensive and simpler manufacture and a smaller proportion of material to be disposed of after use. Therefore, film packs are preferred.
  • the separating element delimits, with the inner wall of the outlet nozzle, a first channel and a second channel, both of which are in flow connection with the first fastening portion via the first passage, the first channel extending completely in the axial direction and the second channel having a first axial portion , a second axial portion and an intermediate therebetween extending obliquely to the axial deflection region.
  • a particularly simple embodiment results from the fact that the deflection region has at least one deflection wall running at an angle to the axial direction. This directs the mass flow in the second channel in the desired direction and this also gives a cross-directional component, which also favors the subsequent mixing with the mass flow from the other container.
  • the deflection region also serves as a throttle for the mass flow from the second passageway. This ensures that the possibly different flow velocities of the mass flows from the two containers is compensated by braking the mass from the second container.
  • the second axial portion of the second channel extends in the axial direction seen downstream of the second passageway.
  • the first channel and the second axial portion of the second channel in a plan view of an outlet opening of the outlet nozzle are arranged diagonally to each other.
  • the mass flow from the first container is thus divided so that it is arranged evenly when leaving the outlet nozzle between the mass flow from the second container, which contributes to a particularly homogeneous subsequent mixing.
  • both channels are executed closed except for one inlet opening and one outlet opening.
  • both inlet openings are in the region of the first passage opening in the head part, and the outlet openings are arranged in the region of the outlet opening of the outlet nozzle. Due to the fact that both channels are otherwise closed, no mixing of the material components takes place in the region of the outlet nozzle; through the two channels, only the mass flow from the first container is divided and rearranged. Since no premixing of the components takes place, premature reaction of the material components and their setting or curing is effectively prevented.
  • the cross-sectional areas of both channels over its length are the same size, so that the material component from the first container is divided into two equal mass flows and the predetermined by the outlet openings of the container mixing ratio of the mass flow from the first container to the mass flow from the second container unchanged remains.
  • the separating element advantageously extends over the entire height of the outlet nozzle, which prevents unwanted premature reaction of the material components.
  • the separating element is designed as a separate insert part.
  • the separating element can also be used in conventional containers and is also characterized by a simple production.
  • the separating element is in particular formed in one piece.
  • the outlet nozzle preferably has an external thread for a separately alsschraubbaren static mixer attachment, in which case a commercial static mixer can be used. Due to the separating element is an improved mixing of the material components, especially at extreme mixing ratios achieved. Likewise, of course, the use of a comparison with the prior art shortened static mixer attachment with the same mixing effect is possible.
  • the first container has a smaller diameter along its entire length than the second container.
  • the first container then contains, for example, a hardener, while the second container is filled with resin. Since the first container contains the smaller volume, a particularly good mixing of the two components is ensured by dividing the mass flow from the first container.
  • the object set in the introduction is likewise achieved by a separating element for an outlet nozzle of a container as described above, wherein the separating element has a first guide channel and a second guide channel which define an inner wall of the outlet connector with a first and a second channel, which at least divide a container of the container into several streams.
  • the separating element of the invention with which a pre-separation of the mass flows to be mixed is achieved, can be used in ordinary, commercial containers and is characterized by a simple production and assembly.
  • the embodiments shown comprise a film container as a container, the invention is not limited thereto. It will be understood by those skilled in the art that the described embodiment can be transferred to other types of containers, such as a hard cartridge, without further adjustments.
  • the Figures 1 and 2 show a container 10 according to the invention in the form of a film container for storing a multi-component mass comprising a first foil bag as the first container 12 and a second foil bag arranged next to the first container 12 as a second container 14 for separately mounted components of the multicomponent mass.
  • the film bag 12, 14, in the Figures 1 and 2 are merely indicated, are elongated and not rigidly formed in the unfilled state.
  • the first film bag 12 has a smaller diameter along its entire length and thus a lower capacity than the second film bag 14.
  • the film package 10 also has an intrinsically stiff head portion 16, which has a common outlet nozzle 18 with an outlet opening 19 and a first attachment portion 20 for one end 22 of the first foil bag 12 and a laterally disposed second attachment portion 24 for one end 26 of the second foil bag 14.
  • Both foil bags 12, 14 are closed at its upper end 22 and 26 with a clip, similar to a sausage package, and have z. B. over a predetermined breaking point, which is not shown in the figures.
  • the first attachment portion 20 is connected via a first passageway 28 with the outlet nozzle 18 in flow communication; the second attachment portion 24 is fluidly connected to the common exit port 18 via a second passageway 30.
  • the outlet nozzle 18 has an external thread 32 on which a separately formed static mixer attachment (not shown) can be screwed.
  • a separating element 34 is provided, which is formed in one piece and as a separate insert and is inserted or inserted into the outlet connection 18 (see FIG. 2 ).
  • the separating element 34 extends over the entire height of the outlet nozzle 18 and has a first guide channel 36 which defines a first channel 40 with an inner wall 38 of the outlet nozzle 18 (see also FIG FIGS. 3 to 5 ).
  • the first channel 40 extends completely in the axial direction A and is arranged at the end facing the passage channel 28 immediately adjacent to a second channel 42 which is bounded by a second guide groove 43 and the inner wall 38 of the outlet nozzle 18.
  • Both channels 40, 42 are via the first passageway 28 with the first mounting portion 20 and thus in fluid communication with the first film bag 12.
  • the second channel 42 is not completely parallel to the axial direction A, but has a first axial portion 44, to which an obliquely to the axial direction A extending deflection region 46 connects, which in turn into a second axial section 48 passes.
  • the deflection region 46 has two deflection walls 50 and 52 running obliquely to the axial direction A.
  • the second channel 42 a partial mass flow is deflected by the first passageway 28, wherein the second axial portion 48 of the second channel 42 seen in the axial direction A downstream of the second passageway 30, which is in flow communication with the second mounting portion 24 extends.
  • the first channel 40 and the second axial portion 48 of the second channel 42 are arranged diagonally to each other, in particular from FIG. 4 is apparent.
  • the first channel 40 thus has an inlet opening 54, which is arranged in the region of the first passageway 28, and an outlet opening 56, which is located in the region of the outlet opening 19 of the outlet nozzle 18.
  • the second channel 42 has an inlet opening 58 arranged next to the inlet opening 54, likewise in the region of the first passage channel 28 (FIG. FIG. 5 ), and an outlet opening 60, which is arranged in the region of the outlet opening 19 of the outlet nozzle 18, in a plan view of the outlet opening 19 diagonally opposite the outlet opening 56 (see FIG. 4 ).
  • both channels 40, 42 are designed so that no mixing of the mass flows from the first foil bag 12 and the second foil bag 14 takes place in the region of the outlet nozzle 18.
  • both channels 40, 42 are the same size, whereby the separating element 34 divides the mass flow from the first film bag 12 into two equal partial mass flows.
  • the deflection region 46 which deflects the partial mass flow in the second channel 42 at an angle to the axial direction A, simultaneously serves as a throttle for the mass flow from the second passage 30 and thus from the second film bag 14.
  • the separating element 34 which in the FIGS. 6 to 14 is shown separately from different perspectives, so divides the mass flow of the first film bag 12 of the film pack 10 in two equal partial flows, whereby in a subsequently passed static mixer better mixing of the material components is achieved.
  • the partial flow in the second channel 42 crosses the mass flow from the second film bag 14.
  • three mass flows arrive at the outlet opening 19 of the outlet nozzle 18, which provides for improved mixing.
