Oblique Perforated Bottle Pack Panel for Easy Access Without Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shrink-wrapped bottle packaging lacks efficient access to individual bottles while maintaining structural rigidity, often causing damage to bottles during perforation.
Innovation Solution
A perforated panel assembly with alternating series of cuts and lands, including oblique-oriented perforations, is integrated into the shrink-wrapped bottle pack to facilitate easy access without damaging the bottles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional shrink-wrapped bottle packaging is used, then structural rigidity is maintained, but access to individual bottles is inefficient and may cause damage
Solution Approach 1:
The packaging structure is segmented into a removable panel portion and a remaining shrink wrap portion. The perforated panel is divided into multiple perforations that can be sequentially removed, allowing access to individual bottles without compromising the integrity of the remaining packaging. This segmentation enables selective access while maintaining overall structural rigidity.
Solution Approach 2:
The removable panel is extracted as a separate functional element from the main shrink wrap. This extracted panel can be removed independently to access individual bottles, separating the access function from the structural containment function. The extraction allows the main packaging to maintain rigidity while providing efficient access points.
2Ease of operation
If perforations are added for bottle access, then ease of access is improved, but structural rigidity of shrink wrap deteriorates
Solution Approach 1:
The shrink wrap is segmented into a removable panel portion containing the perforations and a remaining portion that maintains structural integrity. By separating these functions into distinct segments, the perforations provide access without compromising the strength of the main packaging structure.
Solution Approach 2:
The removable panel is positioned at specific locations (top, bottom, or sides) where access is needed, while the rest of the shrink wrap maintains its full structural rigidity. This local modification approach concentrates the access functionality in specific areas rather than compromising the entire packaging structure.
3Productivity
If oblique-oriented perforations are used, then access efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The perforations are configured with oblique orientations rather than uniform straight lines, creating asymmetric patterns that provide better access efficiency. The alternating series of oblique perforations allows for more effective bottle removal while the pattern can be designed to match the bottle arrangement geometry.
Solution Approach 2:
The perforations extend across multiple dimensions of the packaging structure, with portions on top panels and side panels. This three-dimensional configuration of perforations provides superior access efficiency compared to two-dimensional flat perforations, allowing users to access bottles from multiple angles.

AI summary
A perforated panel assembly disposed in a shrink-wrapped bottle pack includes a first perforation extending from a customer access portion on a top side of the shrink-wrapped bottle pack. The first perforation includes a portion thereof positioned on a first side of the shrink-wrapped bottle pack and defining a first plane. A second perforation extends from the customer access portion on the top side of the shrink-wrapped bottle pack. The second perforation includes a portion thereof positioned on the first side of the shrink-wrapped bottle pack and defining a second plane. The first plane is oriented obliquely to the second plane.
