Sinusoidal Sidewall Channels for Beverage Container Elongation Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plastic beverage containers are susceptible to deformation due to thermal contraction and pressure differentials, leading to paneling and elongation, which affects their structural stability and stacking efficiency.
Innovation Solution
The beverage container features sinusoidal continuous channels and linear channel segments on its sidewall, which resist elongation and paneling by providing hoop strength and maintaining a cylindrical shape, even when filled with high-temperature beverages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If plastic beverage containers are used, then light weight and ease of production are improved, but structural stability and resistance to deformation deteriorate
Solution Approach 1:
The continuous channel is segmented into multiple sinusoidal sections with peaks and troughs, creating a series of reinforcing ribs that distribute structural support throughout the sidewall. This segmentation allows the plastic container to maintain strength while using minimal material, resolving the contradiction between light weight and structural stability.
Solution Approach 2:
The sinusoidal channel design introduces curved, wave-like patterns into the sidewall rather than using straight lines or flat surfaces. This curvature creates natural arches that distribute stress more effectively, enhancing structural stability without adding significant weight to the container.
2Adaptability or versatility
If high-temperature beverages are filled, then product versatility is improved, but container deformation and paneling worsen
Solution Approach 1:
The sinusoidal channels are pre-formed into the sidewall during manufacturing, creating preemptive structural reinforcement that counteracts the thermal contraction forces before they can cause deformation. This preliminary structural preparation allows the container to withstand high-temperature filling without paneling, enabling versatile beverage packaging while maintaining shape stability.
3Productivity
If container deformation is prevented, then stacking efficiency is improved, but manufacturing complexity worsens
Solution Approach 1:
The sinusoidal channel design combines multiple functions into a single structural feature: it provides deformation resistance, maintains cylindrical shape, and creates uniform stacking surfaces. By merging these functions into one integrated channel system rather than adding separate components, the design improves stacking efficiency without proportionally increasing manufacturing complexity.

AI summary
A beverage container that includes a base, a cylindrical sidewall extending from and integrally formed with the base, and an upper region extending from the sidewall and defining an upper opening. The beverage container includes a longitudinal axis extending in a direction from the base to the upper opening. The beverage container further includes a continuous channel formed in and extending around a circumference of the sidewall. The continuous channel is sinusoidal such that the continuous channel forms peaks and troughs. A height of the continuous channel as measured in a direction of the longitudinal axis from a peak to a trough is about 30% to 80% of a height of the sidewall, such that the continuous channels resists elongation of the beverage container in a direction of the longitudinal axis.
