Bottle Panel Ribs for Pressure Absorption and Label Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bottles with recessed panel portions in the radial direction for pressure reduction often result in a poor appearance of labels due to deformation, compromising both pressure absorption performance and aesthetic quality.
Innovation Solution
A bottle design featuring panel portions recessed in the radial direction with ribs protruding outward, supported by pillar portions, which restrict label movement and maintain pressure absorption while preventing angular deformations and crimping, ensuring a smooth label appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If panel portions are recessed toward the inside in the radial direction to absorb pressure reduction, then pressure reduction-absorbing performance is improved, but label appearance deteriorates due to deformation and angular portions
Solution Approach 1:
The body is segmented into panel portions and pillar portions, where panel portions absorb pressure reduction through radial deformation while pillar portions maintain structural integrity and support the label, preventing the label from following the deformation and maintaining its appearance
Solution Approach 2:
Different regions of the body are given different properties: panel portions are designed to deform radially for pressure absorption, while pillar portions are designed to remain relatively rigid to support the label and prevent deformation-induced appearance degradation
2Shape
If panel width is reduced to prevent label displacement, then label appearance is improved, but pressure reduction-absorbing performance deteriorates
Solution Approach 1:
The body is divided into panel portions for pressure absorption and pillar portions for structural support, allowing the panel portions to be sufficiently wide for pressure absorption while the pillar portions maintain label support function
Solution Approach 2:
The pillar portions act as intermediaries between the panel portions and the label, providing structural support that prevents the label from being displaced by pressure-induced deformation while allowing the panel portions to deform for pressure absorption
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The bottle effectively absorbs pressure changes while maintaining a desirable appearance by supporting labels from the inside and preventing displacement, thus combining pressure reduction performance with aesthetic integrity.
Implementation Method 1
when the temperature of contents sealed in the bottle is lowered, and a pressure in the bottle is reduced, the panel portions are preferentially deformed toward the inside of the body in the radial direction. Thereby, the pressure in the bottle is configured to be absorbed
Implementation Method 2
a rib which protrudes toward the outside in the radial direction while having a gap with respect to a longitudinal lateral wall portion of the lateral wall portion is provided at the panel bottom wall portion

AI summary
A bottle (1) includes a cylindrical body portion (13) in which a plurality of panel portions (15), which is recessed toward an inside in a radial direction of the body portion, are provided at intervals in a circumferential direction and pillar portions (52) are each provided between the panel portions (51) adjacent to each other in the circumferential direction. The panel portions (51) each have a panel bottom wall portion (53) located at an inside of the body in the radial direction and have a lateral wall portion (54) extending from an outer circumferential edge of the panel bottom wall portion (53) to an outside in the radial direction. A rib (55) which protrudes toward the outside in the radial direction while having a gap with respect to the panel bottom wall portion is provided at the panel bottom wall portion (54), and a longitudinal lateral wall portion (54a) is at least directed in the circumferential direction.
