Container having enhanced wall integrity and alignment element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thin-walled disposable plastic containers are prone to bending, distortion, and instability due to their thin walls, and they often fail to nest properly when stacked, leading to increased storage space requirements and potential instability.
Innovation Solution
The design incorporates a polygonal cross-sectional shape with a rotational alignment structure that allows containers to self-align and nest fully, enhancing structural integrity and reducing material thickness while ensuring proper stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If thinner material is used for container walls, then production cost is reduced, but the container becomes more prone to bending, distortion, and collapsing
Solution Approach 1:
The container sidewall is divided into multiple panel sections separated by reinforcement ribs. The ribs act as structural dividers that segment the thin-walled sections, preventing them from collapsing independently while maintaining overall container strength with minimal material usage.
Solution Approach 2:
Reinforcement is applied locally at critical areas where ribs are positioned, rather than uniformly thickening the entire sidewall. This allows the majority of the sidewall to remain thin for cost efficiency, while specific localized regions gain enhanced strength where structural support is most needed.
2Volume of stationary object
If containers are stacked for storage and shipment, then storage efficiency is improved, but containers may not fully nest and become unstable
Solution Approach 1:
The container features an asymmetric profile with a tapered sidewall that transitions from a larger top opening to a smaller bottom base. This asymmetric geometry allows containers to nest within each other like Russian dolls, maximizing storage density while the tapered shape provides natural stacking stability through gravitational alignment.

AI summary
A container having enhanced wall integrity is provided that includes a sidewall comprising at least one alignment structure formed therein or as a part thereof. The alignment structure is adapted for orienting the container with respect to a second container such that the containers become aligned or indexed such that they may be fully nested one within the other. The alignment structures can each include a protrusion that extends radially outwardly relative from the sidewall to form peaks along an external surface of the container and valleys along an inner surface of the container. Each alignment structure may further include an alignment ridge protruding from the peak of the alignment structure. Such alignment ridges may project outwardly from a remainder of the peak of the alignment structure at an angle, radius, or curvature that is different than that of the remainder of the peak.
