Package Kit with Closure Strap and Slits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packages fail to efficiently utilize material, are difficult to transport and prepare for use, lack mechanical stability, and are not conveniently reusable without damaging the package during resealing or reclosing.
Innovation Solution
A kit of blanks comprising a first blank to form a package and a second blank to form a closure strap, with slits allowing the elongated body part to extend into and out of the package, forming a tensioned closure strap that keeps the package closed without adhesives, and includes double-walled side walls for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is used to reseal or reclose the package, then the package can remain closed during handling and transportation, but the package may be damaged and becomes difficult to disassemble and recycle
Solution Approach 1:
The patent replaces the chemical bonding mechanism (adhesive) with a mechanical closure system consisting of a closure strap and locking mechanism. The closure strap extends around the package and engages with locking features on the package body, providing reliable closure through mechanical interlocking rather than adhesive bonding. This allows the package to remain securely closed during handling and transportation while enabling easy mechanical disassembly by simply releasing the locking mechanism, thereby maintaining recyclability without damage.
2Strength
If the package is designed to be mechanically stable, then it can withstand handling and transportation, but it may be difficult to transport and prepare for use
Solution Approach 1:
The package is divided into separate modular components: a package body, a closure strap, and locking mechanisms. These components can be flattened and packaged separately for efficient space utilization during shipping, then easily assembled at the point of use by simple folding and locking actions. The segmentation allows the package to achieve mechanical stability through proper assembly while maintaining ease of transport and preparation.
Solution Approach 2:
The closure strap and locking mechanisms are pre-configured in the blanks with predetermined fold lines and engagement features. This preliminary configuration allows for rapid assembly at the point of use without requiring complex tools or procedures. The pre-formed structure ensures mechanical stability is achieved through proper alignment of components, while the simplicity of the preliminary configuration maintains ease of operation during preparation.
3Loss of substance
If material is used efficiently in the package design, then waste is reduced, but the package may lack mechanical stability
Solution Approach 1:
The package utilizes thin-walled construction with strategically placed reinforcement elements rather than uniformly thick material. The closure strap acts as a flexible element that provides structural support where needed while allowing material savings in non-critical areas. The locking mechanism concentrates material usage at key stress points, achieving mechanical stability with overall material efficiency by avoiding unnecessary material in areas that do not contribute to structural integrity.
