Definitions

  • the invention relates to a packaging system for a curable multicomponent composition and to the use of the packaging system for mixing and / or processing a multicomponent composition, in particular for an adhesive, a sealant or a construction foam. Furthermore, the invention relates to a method for processing the multicomponent mass using the packaging system.
  • a reactive material of two components is mixed on site and placed in the opening.
  • the reactive material should be stable until hardened and should not flow out of the opening again.
  • the stability is achieved by a corresponding adjustment of the viscosity of the material.
  • the reactive components are presented separately in two-component cartridges with a static mixer and mixed at the application site by pressing out of the cartridge in the static mixer.
  • the US 2013/0277393 A1 relates to a device for applying multicomponent masses with two exchangeable cartridges and a mixing unit.
  • two-component cartridges with static mixer have a certain dead volume in the mixer and the mixing quality is at the beginning insufficient. Therefore, one must take a lead, which is to be discarded. Furthermore, these systems always leave a residual amount in the mixer.
  • Static mixers are not suitable for mixtures of powder components and liquids, because bridging occurs in the powder component, which prevents mixing in the static mixer by pressure. From powder and liquid existing masses are therefore mechanically mixed together in an open vessel with the help of stirring rods or other mixing aids. The mixed mass can then be manually introduced into the opening to be filled and / or brought into the desired shape, or filled in other application aids such as dough presses and introduced into the opening.
  • the powder is to be mixed with the liquid in a closed rigid container, additional aids such as balls are needed in a partially air-filled space.
  • additional aids such as balls are needed in a partially air-filled space.
  • the application of the mixed mass from the rigid container is difficult.
  • a substantially liquid consistency of the mixture is required.
  • a partial emptying can be achieved by the use of a laterally somewhat compressible plastic bottle. A good emptying or even an application "overhead" is not possible.
  • Multi-component systems for the production of gypsum foams and / or cement foams by mixing in open vessels for example, from EP 2 045 227 A known.
  • the hydraulically setting composition described therein serves for the production of inorganic fire-resistant or insulating foams and comprises a pH-neutral or alkaline hydraulic binder and a foaming component as well as a foam stabilizer, the foaming component releasing oxygen or carbon dioxide.
  • the known inorganic fire protection systems are difficult to introduce into openings and are often applicable only as a potting compound with elaborate formwork devices.
  • liquid two-component casting resins which are introduced into a two-chamber foil bag with clamp closure.
  • the potting resin is mixed by hand after removing the clamp closure and then cast for example in cable lugs.
  • Clamp bags are sufficient for liquid casting resins because the mass can flow out of the bags.
  • Clamping bags are less suitable for stable masses, since the mixing of the components by kneading must be done by hand and therefore the mixing quality is difficult to control and reproduce. Therefore, the clamping bags are not used for eg chemical adhesive bucket, because even small quantities of subsets must be well mixed in order to ensure a sufficient load.
  • the pressing of the stable mass from the clamping bag is difficult, since a high pressure must be applied.
  • Rotary tube packages with two intermeshing tube sleeves have hitherto been used only for packaging but not for mixing and processing multicomponent systems due to the high "dead volume” of more than 50% after nesting.
  • the invention has for its object to provide a simple, user-friendly and cost-effective packaging for multi-component masses, with which the masses can be safely mixed and applied with a small residual amount from the package and applied.
  • the packaging should allow the mixing of the components without expensive tools and allow the introduction of the masses produced in tight and / or difficult to access openings.
  • the packaging should serve for the processing of inorganic and organic compounds such as chemical anchors and in particular also inorganic foams for fire protection applications.
  • the invention further provides a process for the production and / or processing of a multicomponent system, in particular for a local foam of a multicomponent inorganic foam system, having the features of claim 16 and preferably using the inventive Packaging system.
  • the invention relates to the use of the packaging system according to claim 18 for packaging and / or processing a multi-component system, in particular for an inorganic fire-resistant foam.
  • the invention provides a packaging system for a multi-component mass comprising a cylindrical housing and a foil bag received in the cylindrical housing.
  • the foil bag has a first end with an opening portion for discharging the multicomponent mass and a second end opposite the first end.
  • the cylindrical housing comprises a sleeve-shaped upper part and a sleeve-shaped lower part, which are in engagement with each other and can be moved against each other.
  • the upper part comprises an end wall with an outlet opening for the multicomponent mass and a means for fixing the first end of the foil bag, so that the opening section communicates with the outlet opening.
  • the lower part comprises a means for fixing the second end of the film bag, so that the film bag is rotatable in the cylindrical housing.
  • the present invention provides a Packaging for a multi-component mass ready, which has a sufficient rigidity of the housing for the mixing process.
  • the rigidity of the cylindrical housing also makes it possible to mix the multicomponent mass only by shaking, whereby a more controllable mixing behavior is achieved than crizspielswese by kneading. By specifying the number of shaking operations or the duration of the mixing, application errors by the user can be avoided.
  • the attachment of the film bag at the ends of the housing parts makes it possible to twist the foil bag and thereby wring out the mass of the foil bag, so that the mass previously mixed, for example, by shaking can be expelled from the foil bag.
  • the film bag is twisted and compressed from the end, so that easily sufficient forces for discharging the mass can be applied from the foil bag. In this case, a very good residual emptying is achieved and there are hardly any remains of the curable multicomponent composition in the bag.
  • the packaging system according to the invention is particularly suitable for mixing powders with liquids to form the multicomponent mass.
  • the user receives a multi-component compound which already has a high mixing quality in the packaging.
  • no lead must be removed, which would have to be discarded.
  • the sleeve-shaped housing parts can be produced inexpensively.
  • a necessary for the formulation of the finished mass liquid such as water can also be introduced on site through the opening portion in the foil bag. Thus, a reduction of the transport weight is possible.
  • the hand-held packaging system of the present invention is particularly suitable for various package sizes.
  • the film bag contained in the packaging system according to the invention makes it possible to provide a container with fixed, predetermined by the packaging quantities of To provide components for the multi-component mass. Thus, a misdosing by the user can be safely avoided and the mixture is ready for immediate use.
  • a foil bag in particular a multi-chamber foil bag, inserted into the cylindrical housing and the two ends of the bag can be fixed to the sleeve-shaped housing top and bottom, in particular by clamping the opening portion to an end wall of the upper part and the opposite end the foil bag at a bottom of the sleeve-shaped lower part in the receptacles provided therefor.
