Removable Bottle Packaging With Releasable Couplings for Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging devices for cosmetic products are difficult to disassemble and recycle due to complex fastening mechanisms, leading to inefficient disposal and recycling processes.
Innovation Solution
A packaging device with a removable bottle design that allows for easy disassembly and reassembly, featuring releasable coupling means such as bayonet-type connections and snap-type couplings, enabling the bottle to be separated from the case and dispenser assembly for recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex fastening mechanisms are used to secure the bottle in the case, then the reliability of the packaging device is improved, but the ease of disassembly and recycling is worsened
Solution Approach 1:
The packaging device is divided into separable modules: the case, the bottle, and the dispenser assembly. Each component can be independently removed and recycled, eliminating the need for complex fastening mechanisms while maintaining secure connection during use through simple snap-fit or screw couplings.
Solution Approach 2:
The coupling mechanism transitions from a static, permanent fastening system to a dynamic, reversible connection. The bottle and dispenser assembly can be easily coupled and decoupled multiple times, allowing for refilling, replacement, or recycling without damaging the components.
2Stability of the object's composition
If permanent fastening mechanisms are used to fix the container in the shell, then the stability of the packaging device is improved, but the productivity of disposal and recycling processes is worsened
Solution Approach 1:
The packaging system is segmented into removable components (container, shell, dispenser) that can be quickly separated. This allows recycling facilities to process each component independently and efficiently, dramatically increasing productivity compared to permanently bonded assemblies.
Solution Approach 2:
The design enables easy discarding of the outer shell and recovery of valuable components like the glass bottle and metal dispenser mechanisms. The simple coupling allows rapid separation and recovery of recyclable materials without complex disassembly tools or processes.
3Manufacturing precision
If tool insertion through shell side openings is required to engage fasteners, then the manufacturing precision of the packaging device is improved, but the device complexity is worsened
Solution Approach 1:
The complex tool-based fastening system is extracted and replaced with a simple manual coupling mechanism. The bottle can be directly inserted into the case and secured by simple snap-fits or threaded connections visible from the top, eliminating side openings and tool requirements while reducing overall device complexity.

AI summary
A packaging device includes a case, a bottle to contain a product to be dispensed, and a dispenser assembly situated at the top of the case and configured to dispense the product contained in the bottle. The bottle is housed in a manner such that the bottle is removable from the case, and can be mechanically coupled, in a removable fashion, to either the case or the dispenser assembly.
