Liquid Storage Container Label Segmentation for Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid storage containers with label members attached to cover liquid supply ports face challenges in maintaining secure attachment during distribution and use, where one part of the label is detached, making it difficult to readily detach the label while keeping the other part securely attached, which increases the load required for detachment.
Innovation Solution
A liquid storage container design featuring a label member with a first area and a second area of different bonding strengths, where the second area covers the liquid supply port and has a score line along its boundary, allowing for easy detachment of the label member by applying a weak adhesive to the second area and a strong adhesive to the first area, enabling secure attachment of the information-bearing portion while allowing easy detachment of the other portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a label member is attached to cover the liquid supply port, then liquid leakage and evaporation are suppressed, but the label member becomes difficult to detach and requires high detachment load
Solution Approach 1:
The bonding face of the label member is divided into a first area with strong adhesive and a second area with weak adhesive. The second area includes a score line that facilitates easy detachment. This segmentation allows the label to remain securely attached during distribution while enabling easy removal when needed.
Solution Approach 2:
Different areas of the bonding face have different adhesive properties. The first area has strong bonding strength to ensure secure attachment during distribution, while the second area has weak bonding strength to allow easy detachment. This local quality differentiation resolves the contradiction between secure attachment and easy removal.
2Reliability
If the label member is securely attached during distribution, then liquid evaporation is prevented, but detachment load increases making it difficult to remove
Solution Approach 1:
The bonding face is segmented into regions with different adhesive strengths. The first area provides strong attachment for security during distribution, while the second area with weak adhesive and score line reduces the force required for detachment.
Solution Approach 2:
The adhesive strength parameter is changed across different areas of the bonding face. By varying the adhesive property from strong in the first area to weak in the second area, the label maintains secure attachment during distribution but requires minimal force for removal.
3Ease of operation
If one part of the label is detached, then accessibility is improved, but the information-bearing portion may become detached during use
Solution Approach 1:
The label member is segmented into a first area with strong adhesive for the information-bearing portion and a second area with weak adhesive for easy detachment. This ensures that when part of the label is removed, the important information-bearing portion remains securely attached.
Solution Approach 2:
Different functional qualities are assigned to different areas: the first area has strong bonding to maintain information-bearing portion attachment, while the second area has weak bonding to provide accessibility. This local differentiation resolves the contradiction between accessibility and reliability.

AI summary
A liquid storage container for storing a liquid has a label member attached to a surface thereof. A bonding face of the label member that is bonded to the surface includes a first area and a second area having a low bonding strength. The second area covers a liquid supply port. A score line is formed on the label member, and the score line extends along a boundary between the first area and the second area and is formed in the second area.
