Polymeric Container Grip Panel Side Load Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing polymeric containers are prone to denting and deformation under side-load forces during handling and transportation, which compromises their structural integrity and visual appeal.
Innovation Solution
The development of polymeric containers with grip panels that have a specific depth, height, and width configuration, providing enhanced rigidity and resistance to denting and crushing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing container grips are used, then grasping function is provided, but resistance to denting and crushing is insufficient
Solution Approach 1:
The patent applies local quality by creating grip panels with specific dimensional proportions (depth at least 17% of height and at least 10% of width) in the grip area. These panels have different structural characteristics than the rest of the container body, providing enhanced local strength and dent resistance where mechanical stress is most likely to occur during handling and transportation.
Solution Approach 2:
The grip area is segmented into multiple discrete grip panels rather than being a continuous structure. This segmentation allows each panel to independently absorb and distribute point-load forces, preventing force concentration that would lead to denting and crushing while maintaining the overall grip functionality.
2Loss of substance
If container wall thickness is reduced for light-weighting, then material usage decreases, but structural resistance to point-loading decreases
Solution Approach 1:
Instead of uniformly thickening the entire container wall, the patent implements localized structural enhancement through grip panels with specific depth, height, and width proportions. This allows material to be concentrated where it is most needed for point-load resistance while keeping the rest of the container lightweight, achieving light-weighting without sacrificing structural integrity.
Solution Approach 2:
The grip panels create a composite structure within the monolithic container body, where the panel regions provide enhanced mechanical properties (strength and dent resistance) compared to the base container material. This composite approach allows the container to achieve high point-load strength with overall reduced material usage.

AI summary
A polymeric container including a finish defining an opening. A base is configured to support the container upright. A grip area is between the opening and the base. A plurality of grip panels are at the grip area. Each one of the grip panels has a depth, a height, and a width. The depth is at least 17% of the height, and the depth is at least 10% of the width.
