AI Technical Summary
Conventional adhesive handling systems face issues with premature curing due to water vapor diffusion, particularly during extensive handling processes, leading to high technical requirements and costs due to insufficient storage stability.
A dual-packaging system is employed, using a water vapor diffusion-tight composite film for Pack 1 and a container with handling functions for Pack 2, which includes a tube shoulder for application, and a twisting mechanism to apply adhesive while compressing Packs 1 and 2 simultaneously, creating a peel seam for application.
This system effectively prevents premature curing by ensuring stable adhesive handling and storage, meeting handling requirements without compromising storage stability and reducing costs.
Abstract
Description
[0001] Conventional adhesive handling systems, especially with moisture-curing adhesives, have numerous problems with premature curing of the adhesive during handling due to water vapor diffusion.
[0002] These problems occur more frequently as soon as the adhesive handling is more extensive than just in the packaging of a sealing edge film.
[0003] Weaknesses in the handling functions lead to high technical requirements, costs and complaints due to often insufficient storage stability.
[0004] With our invention, we can easily eliminate these problems and ensure that handling requirements are met regardless of the adhesive packaging.
[0005] These objectives are achieved with the invention described in the claims.
[0006] Pack 1 is based on a simple packaging of the adhesive in a container, preferably in a flexible aluminum composite foil. Other metallic and non-metallic materials are possible.
[0007] This Pack 1 has no problem areas, as in its original form it preferably consists only of a water vapor diffusion-tight composite film.
[0008] Pack 2 includes all technical details for handling, such as a tube shoulder in a free design for applying or back-injecting the adhesive.
[0009] The application device can also be a contour rake to apply the adhesive in a metered, even application.
[0010] These handling applications are only examples and can be individually adapted to the requirements.
[0011] Finally, Pack 1 is placed inside Pack 2 and Pack 2 is closed at the back.
[0012] The adhesive handling now has two functions in independent packaging thanks to Pack 1 and Pack 2.
[0013] By applying the adhesive, preferably with a twisting key, Pack1 and Pack2 are automatically rolled up and compressed simultaneously, whereby the compressed adhesive in Pack1 preferably opens a peel seam or predetermined breaking point and is applied through the handling functional elements or back-injected.
