Emptying Tubes – Completely!
We’ll do anything to empty a tube – squeeze it, press it, fold it, roll it. Until now, all implements have tackled this problem from the outside. Roder Kunststofftechnik GmbH, Lübeck, Germany, joined forces with yello-motive, a concept and product developer, to devise a circular valve which is inserted in the tube and which the user pushes up toward the opening from the outside during use. And, voilà, the end result is a completely empty tube. Dubbed Tubedrain, this new development lends itself equally to all cylindrical aluminum, laminate and plastic tubes; the injection molded insert can be custom sized.
Tubedrain has a dovetail design that prevents the insert from slipping and sliding back down the tube. Lateral stabilizers create a tight seal with the tube wall and keep air out. This minimizes the risk of oxidation and contamination of the tube contents with germs. The contents therefore have a longer shelf life. The drain always remains facing the tube opening. As before, it only requires slight pressure of the thumb and forefinger to empty the tube evenly. Consequently, the outer tube shape and the advertising inscription are virtually unchanged during the product’s lifetime.
Roder Kunststofftechnik has a patent pending on Tubedrain. The developers are convinced that it will soon be in widespread use, not only for sensitive and high-quality contents, but also for personal care and adhesive products. Roder says that reputable brand companies have already made initial inquiries.
