Nestable Wide-Based Disposable Container with Flexible Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable containers lack efficient space-saving stacking capabilities and are prone to deformation during handling and transportation, and they often require cleaning after use.
Innovation Solution
A disposable container design featuring a wide, non-tipping base with a flexible center and a nested, stackable structure, combining a flared rigid portion with a flexible portion, allowing for increased holding capacity and robustness during use and transportation, and enabling easy disposal without cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If disposable containers are designed with a wide base for stability, then non-tipping property is improved, but stacking space efficiency deteriorates
Solution Approach 1:
The patent implements nesting by designing the container with a flared rigid portion that allows one container to be inserted inside another. The flexible portion is configured to be tucked into the rigid portion, enabling compact stacking of multiple containers while preserving the wide base stability feature for individual container use.
2Stability of the object's composition
If disposable containers are made rigid for shape sustenance, then shape stability is improved, but adaptability to surface conditions deteriorates
Solution Approach 1:
The patent applies local quality by using different material properties for different parts of the container. The rigid flared portion provides structural integrity and shape sustenance, while the flexible portion at the base adapts to various surface conditions. This localized differentiation of material properties resolves the contradiction between rigidity and adaptability.
Solution Approach 2:
The container is constructed as a composite structure combining rigid material (for the flared portion) and flexible material (for the base portion). This composite construction allows the container to simultaneously achieve shape stability from the rigid section and surface adaptability from the flexible section.
3Quantity of substance
If disposable containers are designed with high holding capacity, then storage capacity is improved, but material cost and complexity increase
Solution Approach 1:
The nested configuration of the flexible portion within the rigid portion creates an expandable volume that increases holding capacity without proportionally increasing material usage. The nesting structure allows the container to accommodate larger volumes while maintaining a compact form factor when empty.

AI summary
One example of a nestable-stackable wider-based disposable container is composed of a plastic-coated paper frustoconical tube having its wider end edge connected continuously to the mouth of a plastic bag whose capacity is larger than the tube size. For storage, let the wide end of one container to receive the narrow end of another container. The plastic bag of the former is forced to push up inwardly and to cleave tightly to the paper side wall, allowing the later to be compactly nested into the former. For usage, one stands a container on its non-tipping wider end, places items in via its upper narrower opening, discards it as a whole unit when done. Other examples are described and shown.
