Laminated Cardboard Tool Packaging for Easy Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blister packs are environmentally unfriendly, difficult to open, and hinder waste sorting due to inseparable plastic and cardboard components.
Innovation Solution
A package arrangement using a support board made of laminated cardboard panels with a cavity and retention structure, allowing easy opening and recyclability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic clear shell and cardboard are combined using heat and pressure, then the package structure is secure and protective, but the components become inseparable making waste sorting difficult
Solution Approach 1:
The package is divided into separate functional layers: an outer carton box for structural support and an inner blister pack for product containment. These segments remain physically separable after use, allowing the blister pack to be removed and the carton box to be recycled independently, thus resolving the waste sorting difficulty while maintaining package security during transport.
Solution Approach 2:
The inner blister pack containing the packaged item is extracted as a separate removable component from the outer carton box. This extraction allows the blister pack to be taken out for proper disposal or recycling without requiring separation of adhesively bonded components, solving the waste sorting problem while maintaining structural integrity during shipping.
2Reliability
If plastic clear shell is used to enclose the packaged item, then the item is fully visible and protected, but the package becomes environmentally unfriendly
Solution Approach 1:
The material composition of the package is changed from plastic-based to paperboard-based. The outer carton box and inner blister pack are both made from paperboard materials, fundamentally changing the material parameter to eliminate plastic pollution while maintaining protective and visible enclosure functions through appropriate design.
Solution Approach 2:
The package uses disposable paperboard blister packs that can be easily discarded after use. These single-use paperboard containers replace durable plastic shells, accepting short service life in exchange for environmental compatibility and reduced harmful impacts, while still providing adequate protection and visibility during the product's shelf life.
3Ease of operation
If plastic clear shell is torn off from cardboard, then the package can be opened, but part of cardboard remains attached making complete separation impossible
Solution Approach 1:
The package structure is segmented into a removable inner blister pack and an outer carton box. The inner blister pack is designed to be completely separable from the outer box through the opening mechanism, ensuring that no cardboard remnants remain attached to the plastic shell after opening, thus enabling complete component separation for proper disposal or recycling.
4Ease of operation
If scissors or tools are used to cut the clear shell open, then the packaged item can be removed, but the process is laborious and damages the item
Solution Approach 1:
The package incorporates pre-formed opening features such as perforations or score lines on the paperboard blister pack. These preliminary structural preparations allow the package to be opened easily by hand without requiring scissors or other cutting tools, saving time and effort while preventing damage to the packaged item through gentle opening actions.

AI summary
A package arrangement includes a support board. The support board is formed of at least two layers of plate laminated and affixed together. Adjacent two plates of the at least two layers of plate define therebetween a cavity for receiving at least part of a hand tool. Each plate of the at least two layers of plate is fabricated from a material satisfying recycling requirements for the same class of materials.
