Foldable Liquid-Resistant Paperboard Container with Concealed Gussets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable paper packaging is weak, prone to leakage when exposed to liquids, and lacks versatility in accommodating items of varying sizes, often requiring additional materials and visible structural features that detract from aesthetics and functionality.
Innovation Solution
A foldable packaging design featuring inwardly folded gussets and flaps with concealed securing structures, made from liquid-resistant material, allowing for secure containment of items without external hardware or visible folds, enabling stackability and easy decoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If paper material is made pliable for easy folding, then ease of manufacture is improved, but strength and ability to withstand weight or pressure deteriorates
Solution Approach 1:
The patent uses a composite structure combining paperboard with internal gusset elements and locking tabs that distribute mechanical loads. The gussets act as structural reinforcement while the paperboard provides the folding capability, creating a composite packaging system that achieves both pliability and strength.
2Ease of manufacture
If external gussets are used to facilitate folding, then ease of manufacture is improved, but aesthetic appearance deteriorates due to visible external structures
Solution Approach 1:
The patent places the gusset structures inside the container body rather than on the exterior. The internal gussets are nested within the container walls, providing the necessary folding facilitation and structural support while remaining hidden from external view, thus maintaining aesthetic appearance.
3Reliability
If external locking tabs with bulbous portions are used, then reliability of containment is improved, but device complexity increases and aesthetic appearance deteriorates
Solution Approach 1:
The patent extracts the locking function from complex external bulbous tabs and implements it through simpler integrated features. The locking tabs are designed as flat, planar elements that interlock with corresponding slots in the container walls, removing the unnecessary bulbous portions while maintaining reliable containment.
4Manufacturing precision
If paper packaging is designed for specific standardized sizes, then manufacturing precision is improved, but adaptability to various product sizes deteriorates
Solution Approach 1:
The patent incorporates adjustable and flexible elements such as movable dividers, expandable gussets, and elastic retention mechanisms that allow the container to adapt to different product sizes. These dynamic features enable a single container design to accommodate a range of dimensions while maintaining precise fit and secure containment.

AI summary
A foldable packaging which may include a liquid-resistant paperboard form that is foldable to provide an attractive stackable container that resists water leakage, can be assembled without fastening hardware and has concealed gussets. The packaging can be folded into overlapping flaps and wings which are folded and interlocked to define a generally trapezoidal packaging which can receive a variety of different pot sizes and types. The die cut pattern forming the packaging can be of a universal shape but formed in a variety of different sizes to accommodate different sized potted plants.
