Bottle With Varying Wall Thickness For Top Load Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bottles face challenges in balancing structural integrity and weight, as they often require significant material to withstand top loads during handling and shipping, which can lead to increased weight and material usage.
Innovation Solution
The bottle design features varying wall thickness with material redistribution, particularly thickening areas around the shoulder and heel, while reducing material in other sections, to enhance structural rigidity and support higher top loads without increasing overall weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional bottles use uniform wall thickness to withstand top loads, then structural integrity is maintained, but weight and material usage increase
Solution Approach 1:
The bottle employs varying wall thickness throughout its structure, with thicker walls at the heel and shoulder regions where mechanical stress is highest during handling and shipping. The body portion uses thinner walls to reduce weight. This localized differentiation of material properties optimizes strength where needed while minimizing weight overall, resolving the contradiction between structural integrity and weight reduction.
2Strength
If material is redistributed to reinforce specific areas, then load rating efficiency improves, but manufacturing complexity increases
Solution Approach 1:
The invention changes the wall thickness parameter along the height and circumference of the bottle, creating a non-uniform distribution that concentrates material in high-stress areas. This parameter variation is achieved through controlled manufacturing processes that can produce the varying thickness profile in a single forming operation, thereby improving load rating efficiency without proportionally increasing manufacturing complexity.

AI summary
A container includes a body that at least partially defines a product storage region. The container further includes a neck that extends upwardly from the body and that has an opening that opens into the product storage region to allow filling of the product storage region with contents and discharge of those contents. The container further includes a floor and a heel. Some areas of the container have varying material distribution or wall thickness.
