Definitions
- Multi-chamber container for storing and mixing a multi-component liquid
- the invention relates to a multi-chamber container for storing and mixing a multi-component liquid coating or adhesive system having a first chamber for a first mixture component and at least one further chamber for a further mixing component, wherein the first chamber and the at least one further chamber by at least one partition liquid-tight from each other wherein the at least one partition wall comprises a pierceable separating layer, and a piercing member for piercing the pierceable separating layer such that the first and another mixture components mix in the first or at least one further chamber. Furthermore, the present invention relates to a system for applying a coating or an adhesive and a method for mixing a multi-component liquid coating or adhesive system.
- Multi-chamber container of the type mentioned are known from the prior art. They are used, for example, together with paint spray paints for automotive refinish coatings. In one-component paints, these are simply filled into a cup-like container or provided in this, which is placed on the paint spray gun. If two-component coating systems are used, the components must first be mixed before being applied by the spray gun. Usually this is done manually. Be particularly advantageous to prove such systems in which both components are stored separately from each other in different chambers of a screw-on the paint spray gun cup. In this case, the partition wall between the chambers is destroyed for the purpose of mixing the components before the painting process, so that the components flow into each other and mix. The mixture can then be applied immediately afterwards by means of the spray gun.
- Typical two-component coating systems include a binder as a first component and a hardener as a second component.
- lacquer systems are polyurethane lacquers with an isocyanate-containing and an isocyanate-reactive, e.g. hydroxy-containing component, and epoxy paints with an epoxy-containing and an epoxy-reactive, e.g. aminic, component.
- a generic M ehrhunt system of the type described above is known from US2009 / 0188987 Al.
- the release film is pierced by means of a dome, so that the paint components in the lower chamber mix with each other.
- the multi-chamber container disclosed in this document comprises a flexible bag made of a liquid-tight material, which is stretched by an articulated frame. Due to the centrally arranged joint, the bag can be subdivided into two separate sub-volumes, into which the two mixture components can be filled. To blend the components, the frame is stretched so that the liquids can run into each other and mix. Subsequently, the mixture can be discharged via a marginal valve and introduced, for example, in a spray gun. Due to the flexible structure, this variant of a multi-chamber container has advantages in the field of waste disposal, but overall has too high a mechanical sensitivity.
- the spatial separation of the mixture components for the purpose of the longest shelf life is not optimal.
- the wall thicknesses of the flexible bag materials are rather low, so that for solvent-based coating systems a significant swelling or even instability has to be expected. If, on the other hand, foil composites with a metal foil, for example an aluminum foil, are used to prevent swelling, the user can not visually inspect the lacquer materials before they are used.
- the present invention seeks to provide a multi-chamber container for storing and mixing a multi-component liquid coating or adhesive system, on the one hand with a safe storage of Mi s chkomponent s and on the other hand a simple and safe feasible mixing process is possible and further allows a simple application of the mixture.
- a multi-chamber container for storing and mixing a multicomponent liquid coating or adhesive system according to the preamble of claim 1, characterized in that the at least one further chamber is arranged coaxially in the outer container, wherein the separating layer is partially formed in the partition wall , wherein the puncturing element is hollow, in particular cylindrical hollow, is formed and has at least two longitudinally offset openings for introducing one of the first or the further mixture component in the chamber of the other mixture component.
- the multi-chamber container comprises a first chamber for a first mixing component and at least one further chamber for a further mixing component, wherein the first chamber and the at least one further chamber are separated from each other by a partition liquid-tight.
- the number of chambers is therefore not limited, so that the multi-chamber container according to the invention is also suitable for liquid coating or adhesive systems with more than, for example, two components.
- the particular advantage of the multichamber container according to the invention lies in the safe storage of the individual mixture components, without the risk that, if the multichamber container is handled incorrectly, parts of the mixture components can flow into one another. This is ensured by the partition wall provided between the first and the at least one further chamber.
- the piercing element cooperating with the pierceable separating layer ensures the production of a defined liquid-conducting connection between the chambers, so that intensive mixing of the mixture components is possible.
- a partial partition also has the advantage that it is exposed to only slight mechanical stress when moving the multi-chamber container.
- the forces acting on the partition wall when shaking the liquid-filled container are greater, the larger the pierceable and thus inherently mechanically labile separation layer.
- a smaller, not full-surface separating layer of advantage In order to prevent inadvertent mixing due to vibrations, for example, during transport of the containers, therefore, a smaller, not full-surface separating layer of advantage.
- the separating layer is preferably formed by a film material, which on the one hand durable and sufficiently resistant to unintentional pressurization and the chemicals used in each case, on the other hand, however, can be easily and precisely pierced by the piercing element.
- Suitable film materials are metal foils such as aluminum foils, plastic films of ABS, CA, COC, CTA, E / P, ETFE, FEP, PA, PAEK, PAN, PBT, PC, PCCE, PCO, PCT, PDCPD, PE (PE-C, PE-HD, PE-LD, PE-LLD, PE-MD, PE-UHMW, PE-ULD), PEC, PEEK, PESTUR, PESU, PET, PEUR, PHB, PI, POM, PP, PS, PTT, PUR , PVC, PVDF (short designations according to DIN EN ISO 1043-1: 2012-03).
- composite films made of metal and plastic are preferably suitable. These combine properties such as preventing diffusion between the blend components of the individual chambers, sealability to tightly bond respective sheet materials to the material of the chamber container, and mechanical strength to withstand fluid movement in the chambers during transport of the container and easy pierceability.
- Corresponding film composites are known, for example, from the packaging sector for, for example, foods.
- the at least one further chamber is arranged coaxially with the first chamber.
- This coaxial arrangement ensures that, for example, when using the multichamber container according to the invention together with an application unit for the multicomponent liquid coating or adhesive system, in particular a paint spray gun, no disturbing overturning moments occur prior to mixing.
- coaxial arrangements can be realized by particularly simple structural configurations.
- the first chamber is formed by an outer container, wherein the at least one further chamber is formed in the outer container as a cup or cup-shaped insert.
- the relative volume ratio of the first chamber for the first mixture component to at least one further chamber for the further mixture component (s) 1: 1 to 9: 1, preferably 1: 1 to 5: 1. This takes into account the usual volumes to be mixed together in the provision and processing of common liquid coating or adhesive systems.
- the piercing element is hollow, in particular cylindrically hollow, and has at least two longitudinally offset openings for introducing one of the first or the further mixture component into the chamber of the respective other mixture component.
- the mixing process in particular the mixing rate, for example, quantitatively the size of the openings and the internal dimensions of the piercing element are precisely influenced. It makes sense to arrange at least one of the two longitudinally offset openings in the end face of the piercing element, in particular in the region of a cutting edge.
- the piercing element can be made of different materials and also have different geometries.
- the piercing element is pin-shaped or rod-shaped and has a sharpened tip or circumferential cutting edge, which allows a simple and secure piercing of the separating layer.
- the geometry of the piercing element should be designed such that, regardless of the vertical position of the piercing element during and after the piercing a complete emptying of the liquid is ensured from the upper chamber and the outlet opening is not blocked.
- the multi-chamber container according to the invention may comprise more than two chambers.
- the partition between the chambers may be designed so that the first chamber is separated from the second and third chambers via a common partition wall, a first partition wall section separating the first chamber from the second chamber second chamber and a second partition separates the first chamber from the third chamber.
- each door wall section has a puncturable separating layer which is part-surface-shaped with respect to the respective door wall section and which can be pierced by a puncturing element.
- a puncture element can be provided in each case for the second and the third chamber, which pierces the respective wall section on actuation, so that, as a result, the components preferably mix in the first chamber.
- each of the two partitions has a parting layer in each case. If the two partition walls are in alignment with one another, the separating layers of both partition walls can preferably be pierced successively by a single piercing element.
- the partial area extending over the partition wall separating layer is arranged centrally in the partition wall.
- the separating wall surrounding the separating layer is conical. This is due to gravity Leakage of a mixture component in the other chamber and there facilitates the mixing of the two mixture components after the piercing of the separating layer.
- the half opening angle of the cone to the longitudinal axis of the multi-chamber container is preferably not more than 85 °, preferably not more than 80 °.
- the mixing components As a material for producing the multi-chamber container and the first chamber and / or the at least one other chamber are plastics, metals, glass, ceramics and composite materials and coated materials and combinations of the aforementioned materials used. Their selection depends on the requirements arising from the material properties of the mixing components and on the expected mechanical stress profile (for example, use in a paint shop). In any case, the mixing components must not be affected by contact with the material or materials change so that they are unusable, nor may the mixing components themselves change the material or materials, so that they can not fulfill their function as packaging for the mixing components.
- plastic as a material, especially PA, PBT, PE (PE-C, PE-HD, PE -LD, PE-LLD, PE-MD, PE-UHMW, PE-ULD), PET (abbreviated to DIN EN ISO 1043-1: 2012-03).
- PE PE-C, PE-HD, PE -LD, PE-LLD, PE-MD, PE-UHMW, PE-ULD
- PET abbreviated to DIN EN ISO 1043-1: 2012-03
- the multi-chamber container and the first chamber and / or the at least one further chamber are formed from a transparent or translucent material.

- a comparatively long processing time pot life
- processing does not have to take place immediately after the mixing process, which is an advantage depending on the particular application.
- an accelerated chemical reaction crosslinking
- crosslinking takes place, through which the working time is shortened, so that, for example, in the case of an immediately following application of the mixture, rapid hardening takes place Surface takes place.
- the catalyst material may be designed in the form of a catalyst bed which contains a catalyst sorbed reversibly on a substrate.
- a catalyst bed in this case a defined volume is considered, which contains substrate and catalyst, wherein the catalyst can not leave the substrate (for example by using sieve inserts). It is provided according to the invention that the catalyst is reversibly sorbed on the substrate.
- both adsorption and absorption can be considered.
- the sorption can be carried out by soaking the substrate with a solution of the catalyst and then evaporating the solvent.
- the fact that the sorption is reversible means that a sorbed catalyst can also be released back to a liquid phase in an amount effective to catalyze the reaction. Therefore, it is also preferable that the substrate is not graphite or activated carbon.
- Suitable substrates may be solid catalysts and catalyst supports known from heterogeneous catalysis. This includes zeolites / molecular sieves such as zeolite A and zeolite X and other porous ceramics.
- suitable catalysts depend on the nature of the mixed components. If, for example, a polyurethane reaction is to be catalyzed since one mixed component contains one isocyanate-containing compound and the other mixed component contains an isocyanate-reactive compound, preference is given to titanium, zirconium, bismuth, tin and / or iron-containing catalysts. Particularly preferred in this case are dialkyltin dicarboxylates and bismuth carboxylates.
- the outlet opening can be closed with a simple, space-saving closure, for example a screw cap.
- a valve or a separate outlet nozzle when connecting the multi-chamber container, for example with a spray gun, to ensure a controlled discharge of the mixture.
- the multi-chamber container has a recess for receiving an outlet valve, wherein the outlet valve is connectable to the outlet opening.
- the outlet nozzle is held in this recess via a clamping, ie non-positively. This avoids that the outlet nozzle gets lost in the storage phase.
- the piercing element in order to achieve that a complete emptying of a chamber takes place after piercing the pierceable separating layer, the piercing element, as already mentioned, can be shaped in various ways. Preferred are cylindrical rod-shaped forms.
- the first chamber or the at least one further chamber has a guide for the piercing element. It is understood that the guide is adapted to the respective geometry of the major impact element, in order to allow the most precise and preferably axial puncturing movement.
- the piercing element is supported on a curved support surface, wherein the curved support surface merges upon application of force from a first position to a second position, such that the piercing element in the transition from the first to the second position from a first position is displaced to a second position, wherein the piercing element pierces the pierceable separating layer.
- a particularly precise piercing of the separating layer is made possible and at the same time limits the movement of the piercing element in such a way that, if the force applied to the piercing element is inadvertently too high, no damage is caused to the multi-chambered container.
- the arched supporting surface only passes from the first position to the second position when force is applied above a defined threshold.
- the first and / or the at least one further chamber has a closable opening for the introduction of a solvent.
- One of the openings may be identical to the outlet opening.
