Definitions
- the invention relates to a multi-chamber foil pouch for a curable multicomponent composition and to the use of the multichamber foil pouch for packaging and / or processing the multicomponent mass. Furthermore, the invention relates to the use of the multi-chamber foil bag in a process for producing a multicomponent composition, in particular a topical foam and in particular an inorganic fire protection foam.
- 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.
- Bulk and liquid masses are mechanically mixed together in an open vessel using a stir bar or other mixing aids.
- the mixed mass can then be manually introduced into the opening to be filled and / or be brought into the desired shape, or filled in other application aids such as a dough press and introduced into the opening.
- Multicomponent systems for the production of gypsum foams and / or cement foams by mixing in open vessels are known, for example, from EP 2 045 227 A.
- the hydraulically setting composition described therein serves for the production of inorganic fire-resistant or insulating local 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.
- a powder is to be mixed with liquid in a closed container, further aids such as balls are needed in a partially air-filled space. To empty the container, a substantially liquid consistency of the mixture is required.
- liquid two-component potting resins are known, which are introduced into a two-chamber foil bag with clamp closure.
- the liquid potting resin is mixed manually after removing the clamp closure and then poured, for example, in cable lugs.
- a simple and inexpensive packaging for good mixing and application of curable multi-component compositions in a closed container is not known.
- Two-component cartridges or two-component film containers with static mixers have a certain dead volume in the mixer. Furthermore, the mixing quality at the beginning of the mixture is insufficient, so that a flow has to be removed, which is to be discarded. Furthermore, a residual amount remains in the static mixer. In commercial systems, this residual amount is about 30 g of the two-component mass, and the amount taken as a preliminary amount is about 15 g. Per application is therefore expected to be about 45 g loss of curable material. If the user only needs to make a small number of four to five attachment points that require about 10 to 15 grams of mass per attachment point, the percent loss amount is about 50% or more. In addition, a new static mixer is required if additional applications are to be carried out with the same container. When using small amounts of the two-component mass must therefore be expected with high losses and correspondingly high material costs.
- Clamp bags are sufficient for liquid casting resins because the mass can flow out of the bags. Stable pasty masses are worse to work with conventional clamping bags, since the masses must be manually pressed out of the bag with pressure. The emptying of the sack is generally unsatisfactory and users attempt to empty the remainder by crumpling or twisting the sack.
- the invention has for its object to provide a simple, user-friendly and cost-effective application form and packaging for good mixing and application of curable multi-component compositions in a closed container, in particular for chemical anchor or for an inorganic foam based on gypsum or cement mortar for insulation or fire protection applications with solid, powdery and liquid components.
- the application form should allow the mixing of components without expensive tools and allow the introduction of the mass in tight and / or difficult to access openings. In this case, even small quantities without flow losses and / or residual quantity losses should be processed.
- the invention further relates to the use of the multi-chamber film bag according to claim 13 for packaging and / or processing a curable multi-component composition, and a method for producing and processing a curable multi-component material using the inventive multi-chamber foil bag having the features of claim 14.
- the invention provides a multi-chamber foil pouch for a curable multicomponent composition having at least two chambers separated from one another in a liquid-tight manner, one of the chambers being filled with a first component and at least one other chamber being filled with a hardener component for the first component.
- the multi-chamber foil bag comprises a separator which liquid-tightly separates the chambers from each other in a stored condition and, in a condition of use, provides flow communication between the chambers for mixing the first component and the hardener component.
- the bag has an opening portion that can be opened to discharge the mixed multicomponent mass.
- the separating element comprises a clamping rail provided with a longitudinal groove and a clamping strip.
- Either the clamping rail or the clamping strip is firmly connected to an edge of the film bag opposite the opening section.
- the firmly attached to the foil bag edge part of Separating member has an engaging portion, which allows a rotational movement of the fixedly connected part for winding the film bag on the firmly connected part.
- the separator thus combines the function of mutual sealing of the chambers with the function of a retractor. This ensures that the reel for squeezing the bag contents does not have to be provided separately. In addition, eliminates the time-consuming threading of the bag seam in the reel. Since the mixing of the components takes place after the removal of the clamping strip in the closed bag, the mixed mass can be fully utilized. There is no flow, which would have to be disposed of because of insufficient mixing of the components. The reel also allows almost complete emptying even when using foil bags made of plastic, which can not be guaranteed by manual squeezing the bag contents. The use of special Auspresstechnikn can thus be dispensed with.
- the multi-chamber foil pouch according to the invention also makes it possible to provide foil packs with fixed quantities of the reactive components for the curable multicomponent mass predetermined by the pack. Thus, a misdosing by the user can be safely avoided and the mixture is ready for immediate use.
- small containers of about 30 to 100 g can be provided in this way easy and cost-saving.
- the separating element of the multi-chamber foil bag can be easily opened without tools. By simply kneading the components, good mixing results can be achieved.
- the firmly connected to the film bag part of the separating element allows easy operation with one hand, so that the opening portion out with the other hand and the mixed multicomponent compound from the opening portion can be selectively applied in an on-site opening.
- the opening portion may be further formed as a nozzle tip and thus allow a targeted application of the mass in narrow and difficult to access openings.
- the composition may already be in a stable consistency in order to prevent the mass from flowing out of the openings to be filled.
- the invention further provides a cost-effective and space-saving film packaging. During mixing, contact between the user and the reactive components is excluded, so that a health hazard is avoided. Finally, no additional mixing elements such as static mixers and no mixing tools and mixing containers are necessary because the mixing of the components takes place within the film packaging. This eliminates the otherwise necessary cleaning work on the tools.
- the curable multicomponent composition is a curable organic material, in particular based on epoxides, (meth) acrylates or polyurethane.
- the multicomponent composition is an inorganic multicomponent composition
- a hydraulically setting component as a reactive component, which may also be pulverulent, and a water-containing component as a hardener component.

- the multi-chamber foil bag has an opening portion which can be opened to discharge the mixed multicomponent mass.
- the opening portion is preferably comprised by one of the two chambers.
- the at least two chambers are arranged at a distance from each other and between the chambers, a bag section is arranged with a reduced cross-section.
- a better mixing is achieved because the mass can be mutually pressed by a constriction.
- the component of that chamber which is not delimited by the separating element, can be separated from the reduced-section bag section by a further separating element, for example a clamp-type peel seam.
- a further separating element for example a clamp-type peel seam.
- it is also provided to fill the bag section of reduced cross section with another reactive component. The bag section then forms itself a liquid-tight separated from the other chambers chamber.
- the opening portion in this embodiment is preferably comprised of the reduced cross section bag portion.
- the opening section is provided with a screw-in closure welded into the foil bag.
- a screw cap allows the attachment of commercially available cartridge nozzles or nozzle tips with which the multicomponent mass can be discharged from the foil bag depending on the desired application at the application site.
- the opening section for discharging the multicomponent mass may be formed by a nozzle tip or plastic nozzle which is welded into the film bag and preferably has a pointed or conical taper.
- the nozzle tip or plastic nozzle is closed at its free end and is cut at the application site depending on the desired size of the nozzle opening or at an intended weakening zone, such as an annular predetermined breaking point, stopped. If the nozzle tips are provided with weakening zones, no scissors or knife is required to open the extrusion tips. If necessary, the nozzle tip can also be extended by attaching another plastic tip.
- nozzle tips with a conical or tapered extrusion opening and a predetermined opening cross-section allows targeted introduction of the foam system in narrow gaps with poor accessibility.
- on-site openings can be filled quickly, easily and inexpensively with the curable multi-component compound.
- the portion for discharging the foam system is formed by an integrally formed on the film bag spout.
- the spout may be tubular or conical or tapered toward its free end opposite the chamber.
- the spout is provided at its free end with a weakening zone, such as a tear seam, which allows tearing of the spout without tools. In this way, even inaccessible openings can be quickly, easily and inexpensively filled with the multi-component mass.

- one of the chambers 12, 14 of the multi-chamber foil bag 10 is filled with a reactive component 16 and the other chamber 12, 14 with a hardener component 18 for the reactive component 16.
- the chambers 12, 14 separated by the separating element 22 liquid-tight from each other.
- the clamping rail 24 is placed on a flat side of the film bag 10 and the film bag 10 from the opposite Flat side of the film bag 10 held by pressing the clamping strip 28 in the longitudinal groove 26 of the clamping rail 24 ( Figure 2). This results in two separate chambers 12, 14 which are liquid-tightly separated from each other by the compression of the film walls of the film bag 10 in the longitudinal groove 26 of the clamping rail 24.
- the separating element 22 is opened by removing the clamping strip 28 from the longitudinal groove 26 of the clamping rail 24 and so a flow connection between the chambers 12, 14 provided.
- the reactive component 16 is mixed with the hardener component 18 with closed film bag 10 by manual kneading.
- After mixing the components 16, 18 of the opening portion 30 is opened by tearing at the tear seam 38 and the film bag 10 from the edge 32 in the direction of the opening portion 30 on the clamping rail 24 or the clamping strip 28 rolled up. The rolling can take place via the engagement section 34 with one hand while the opening section is guided with the other hand on or in the opening to be filled.
- the separating element 22 by removing the clamping strip 28 from the longitudinal groove 26 of the clamping rail 24 and the further separator 36 (heat-sealed peel Seam) is opened by pressure on the chamber 14, thus providing a flow connection between the chambers 12, 14 via the reduced cross section bag portion 40.
- the reactive component 16 is transferred by pressing and completely emptying the bag 14 in the chamber 12 and mixed with the hardener component 18 with closed film bag 10 by manual kneading. Backflow of the components can be prevented, for example, by pinching off the bag 14 in the area of the bag section 40 of reduced cross-section.
- the bags 12 and 14 separated from each other and is the Opening portion 30 is opened and the film bag 10 from the edge 32 in the direction of the opening portion 30 on the clamping rail 24 or the clamping strip 28 rolled up.
- the rolling can take place via the engagement section 34 with one hand while the opening section is guided with the other hand on or in the opening to be filled.
