Packaging Box With Score Line And Adhesive Tape Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packages sealed with adhesive tape require tools to open, risking damage to contents, and lack easy assembly and external pressure resistance.
Innovation Solution
A package design featuring pairs of opposed side walls, foldable top and bottom flaps, and a weakened area with an internal line that allows easy removal of adhesive tape without tools, ensuring structural integrity and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive tape is used to seal the package, then sealing reliability is improved, but opening difficulty increases requiring tools
Solution Approach 1:
The adhesive tape is pre-applied to the package in a factory setting, creating a pre-sealed state that maintains reliability during transport. The tape is positioned and adhered before the package reaches the consumer, ensuring proper sealing without requiring the consumer to perform sealing actions.
Solution Approach 2:
A score line is introduced as an intermediary element between the adhesive tape and the package flaps. This score line acts as a mediator that concentrates opening force at a specific location, allowing the tape to be removed by pulling along the score line rather than requiring cutting tools. The score line facilitates tape removal by providing a predetermined failure path.
2Ease of operation
If a knife is used to cut the tape for opening, then opening ease is improved, but product damage risk increases
Solution Approach 1:
The score line serves as an intermediary that replaces the need for a knife. Instead of using a sharp instrument that could slip and damage products, the score line provides a safe, predetermined path for force application. The consumer simply pulls the flap along the score line, and the tape releases without cutting into the package or contents.
Solution Approach 2:
The package structure itself, through the integrated score line, provides the opening mechanism without requiring external tools. The score line is built into the package design, allowing the package to open itself when force is applied along the predetermined line, eliminating the need for consumer-owned cutting instruments.
3Ease of operation
If the internal weakened line extends across the adhesive tape, then opening ease is improved, but structural integrity deteriorates
Solution Approach 1:
The score line is designed with local quality by positioning it to terminate before reaching the adhesive tape. This creates a localized opening path in the flap material without compromising the overall structural integrity of the package. The weakness is concentrated only where needed for opening, while the rest of the structure remains strong.
Solution Approach 2:
The score line provides partial opening action by creating a pathway that facilitates tape removal without extending the weakness across the entire tape area. The score line length is optimized to be sufficient for tape removal but not excessive enough to compromise structural integrity. This partial action achieves the opening function without over-weakening the structure.

AI summary
The present invention relates to a box of one or more absorbent articles, the box comprising pairs of opposed side walls, pairs of opposed top flaps foldably connected to corresponding side walls, pairs of opposed bottom flaps foldably connected to corresponding side walls, and a weakened area defined by an external weakened line at one of first opposed side walls. The weakened area comprises a first section and a second section divided by an internal weakened line, and an adhesive tape having a tape width and a tape end, and covering adjacent edges of the second opposed top flaps to seal top of the box. The adhesive tape extends along a portion of the one of first opposed side walls in such a way that the adhesive tape covers part of the second section so as not to cover the internal weakened line.
