US manufacturer of rigid packaging, TricorBraun, has received a patent for a locking configuration that enables two bottles to be slid together and locked.
The system requires a pair of bottles with opposing dovetails that fasten into themselves.
“The design provides remarkable marketing support for two liquid products that a manufacturer wants to be used in combination. This configuration is a logical choice for personal care products such as shampoo and conditioner or hand lotion and sanitizer,” according to Craig Sawicki, Tricorbraun’s executive vice president.
