Definitions

  • the present invention relates to a multi-component packaging for adhesion promoters.
  • Adhesion promoters have been used for some time to improve the adhesion, in particular of adhesives and sealants, to surfaces to be bonded or sealed. Adhesion promoters are used in particular where adhesives adhere insufficiently to a substrate. Adhesion promoters are mostly reactive substances and typically form a film on the surface of a substrate to be bonded or sealed and bond to the substrate to develop a sufficiently high adhesive force to act as a primer, i. that they can transmit forces which act on a bonded or sealed substrate to the adhesive or sealant, as well as the joining partner, without the adhesive or sealing compound is destroyed.
  • a moisture-reactive compound is mixed with a volatile solvent (VOC) and stored in suitable packaging.
  • VOC volatile solvent
  • the volatile solvent evaporates and the humidity causes crosslinking.
  • Two- or multi-component adhesion promoters are characterized in particular by the fact that the components are separated from each other and therefore can be stored for a long time. However, when mixing the components, these two or more components react with each other or one component causes a crosslinking reaction of the other component. It is thus intrinsic to the system that such two- or multi-component adhesion promoters can only be stored for a very short time after mixing the components before application, without losing the adhesion-promoting function with them. When mixing two or more components, it is also important that they are mixed in the correct mixing ratio.
  • this object is achieved by a multi-component packaging having the features of patent claim 1 and / or by a pack having the features of patent claim 15.
  • a multi-component package for a primer consisting of at least a first and second component.
  • the multi-component packaging in this case has a first chamber for receiving the first component of the adhesion promoter, wherein the first chamber has a removal opening for removal of the adhesion promoter.
  • the multi-component packaging has a closure means which closes the removal opening in a fluid-tight manner.
  • the multi-component package is further formed with a second chamber for receiving the second component of the adhesion promoter.
  • the multi-component packaging is provided with a shut-off means, which closes fluid-tightly in a closed position connecting the first and second chamber passage opening and releases in a release position.
  • a seal of the multi-component packaging obstructs access to the closure means in a storage position and releases the access to the closure element in a standby position, wherein actuation of the seal from the storage position to the ready position at the same time the shut-off from the closed position to the release position for mixing the first and second component actuated.
  • the idea underlying the present invention is that for applying the adhesive, the closure means must be removed from the removal opening, the access to the closure means to remove this, however, is blocked by the seal as long as this is in the storage position located. Accordingly, in particular a user, the seal must first spend from the storage position in the ready position to get to the closure element.
  • the seal is in this case coupled to the blocking means that actuation of the seal from the storage position into the standby position simultaneously requires actuation of the blocking means from the closed position into the release position. If the blocking means is now in the release position, the through opening connecting the first and second chambers is at least partially open, so that the first and second components at least partially, if possible completely, mix and the two components can react with each other in the correct mixing ratio.
  • the inventive multi-component packaging especially in the field of manufacturing safety-related components is well usable.
  • a "chamber” is understood to mean a volume together with a wall, wherein the wall encloses the volume almost completely or completely.
  • release of the passage opening in the present case is also understood to mean only a partial release.
  • an upsetting section is provided between the passage opening and the second chamber and the closing means is inserted as a stopper which is inserted into the passage opening in its closed position, a counter surface arranged towards the second chamber pushing the stopper out of the passage opening during upsetting of the upsetting section and thus spends this in the release position, wherein the upsetting of the compression portion associated with the actuation of the seal from the storage position in the standby position.
  • the seal is substantially envelope-shaped, wherein the seal from the storage position in which it surrounds the closure element inaccessible, in particular for a user's hand, in the standby position in which it is the closure element in particular for the hand of the User accessible, movably provided.
  • the closure means, the removal opening, the first chamber, the passage opening, the compression portion and / or the second chamber in the compression direction substantially successively - and preferably in this order - lying on an axis and / or substantially formed symmetrically or rotationally symmetrical with respect to the axis.
  • the seal is provided movably substantially along the axis.
  • the seal can be easily moved from the storage position to the standby position along the axis.
  • the seal could also be accordion-like, wherein it is then set at one end, in particular at the second chamber and is provided to be movable at its other end along the axis, wherein a concertina-shaped portion connects the one and the other end.
  • the seal is provided on the outside of the second chamber guided guided. In this way, the mobility of the seal along the axis can be easily provided.
  • the seal has a substantially hollow cylindrical portion and an at least partially closing end face portion, wherein the hollow cylindrical portion in the storage position of the seal at least the closure means, the removal opening, the first chamber, the through hole and the compression portion accommodates in itself and the front-side portion having an opening for a passage of the closure element when moving the seal from the storage position to the standby position.
  • hollow cylindrical is meant in particular hollow circular cylindrical. The hollow cylindrical portion and the frontal portion together prevent access in the storage position of the seal to the closure element for a user's hand.
  • the opening in the end-side section has a diameter which is smaller than that of the closure element, wherein the seal has an elastic material at least in the region of the opening, wherein the pressure required for expanding the elastic material on the closure element exceeds the necessary pressure for upsetting the compression portion.
  • the removal opening on the outside has a projection which is arranged on the side facing the first chamber of the closure element and has approximately the diameter of the closure element, wherein the frontal portion engages behind the projection with respect to the closure element in the standby position.
  • the opening in the frontal section is closed by means of a sticker in the storage position, wherein the necessary pressure for releasing the sticker on the closure element exceeds the pressure for upsetting the compression section.
  • a sticker is very easy to apply.
  • the sticker may also contain information about the contents of the multi-component packaging. The sticker would thus advantageously have a dual function.
  • the opening in the frontal section is closed by an insert in the storage position, which is coupled to the edge of the opening by means of a predetermined breaking point, wherein the necessary for a breaking of the predetermined breaking point pressure on the closure element the necessary pressure for Upsetting of the upsetting section exceeds.
  • an insert can be advantageous in one piece, in particular in an injection molding process, produce with the seal.
  • a ring of an elastic material between the front-side portion and the first chamber is provided, which has a diameter which is smaller than that of the first chamber, wherein the pressure necessary for an expansion of the ring on the first chamber exceeds the necessary pressure for upsetting the compression portion.
  • the multi-component packaging has a mechanism for preventing an automatic movement of the seal from the ready position to the storage position.
