Label Cut-Outs for Stronger Container Glue Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large labels on containers limit the availability of strong glue joints, as many potential locations for forming glue joints are covered, resulting in weaker bonds and making it difficult to join containers effectively.
Innovation Solution
Creating cut-out sections on the labels, particularly on the rear side, allows for the placement of adhesive points directly on the container, enabling stronger glue joints and increased flexibility in arranging containers without compromising the label's functionality or aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If large labels are used to cover the container surface for publicity or product information, then the label's advertising function is improved, but the number of available locations for forming strong glue joints is reduced
Solution Approach 1:
The label surface is segmented by creating cut-out sections that remove specific portions of the label material. This segmentation allows glue joints to be formed on the container surface in areas where the label would otherwise block adhesive contact, while the remaining label portions maintain their information display function. The cut-out sections create localized openings that enable direct container-label-glue joint formation without compromising the overall label coverage.
Solution Approach 2:
Specific portions of the label are extracted or removed to create cut-out sections. These extracted areas are strategically positioned to provide access to the container surface for forming glue joints. The removed label material is minimal (no more than 20%, preferably no more than 10% or 5% of the total label surface), yet sufficient to enable reliable adhesive bonding while preserving the majority of the label's information display capability.
2Reliability
If cut-out sections are created on the label to enable direct container bonding, then the reliability of glue joints is improved, but the label surface area is reduced
Solution Approach 1:
The label is designed with non-uniform local quality through the introduction of cut-out sections. These localized modifications create specific areas (the cut-outs) with different properties - allowing direct container contact for bonding - while the surrounding label areas maintain their original information display function. The cut-out sections are positioned strategically to provide the minimum necessary access for reliable glue joint formation without unnecessarily reducing the overall label surface area.
Solution Approach 2:
Rather than removing large portions of the label, only partial action is taken by creating small cut-out sections that constitute no more than 20% of the label surface area. This partial removal is sufficient to enable the formation of glue joints with adequate strength while preserving the majority of the label's surface area for displaying product information and branding.
3Shape
If cut-out sections are made small to preserve label appearance, then the aesthetic appeal is maintained, but the flexibility in positioning glue joints is limited
Solution Approach 1:
The solution moves from considering only the two-dimensional label surface to utilizing the third dimension by creating cut-out sections that provide access to the container surface beneath the label. This dimensional approach allows glue joints to be positioned in multiple locations around the container, including areas that would otherwise be completely blocked by the label, thereby increasing placement flexibility without requiring large cut-out sections that would compromise appearance.
