Adhesive Label Comb Structure for Multi-Part Container Anti-Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive solutions for multi-part containers, particularly those with threaded members like Luer-lock syringes, often fail to provide a secure and reliable fixation, leading to unwanted rotation during use or handling.
Innovation Solution
An adhesive label with a comb-like structure and a first flat label portion attached to the threaded member and a second label portion with strip-shaped fixing elements attached to the container body, ensuring a stable and secure coupling of the threaded member to the container body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple adhesive label is used to attach the threaded member to the container body, then the manufacturing cost is reduced, but the reliability of fixation is insufficient
Solution Approach 1:
The adhesive label is divided into two distinct portions: a first label portion for attaching to the threaded member and a second label portion for attaching to the container body. This segmentation allows each portion to be optimized for its specific function while maintaining overall simplicity and cost-effectiveness.
Solution Approach 2:
The second label portion incorporates a comb-like structure with multiple strip-shaped fixing elements that extend in different directions (dimensions) from the main label body. This multi-dimensional arrangement increases the effective bonding area and mechanical interlocking capability, thereby improving fixation reliability without significantly increasing manufacturing complexity.
2Device complexity
If mechanical interlocking alone is used to secure the threaded member, then the device complexity is reduced, but the stability against rotation during use is insufficient
Solution Approach 1:
The invention merges mechanical interlocking (through the comb-like structure with strip-shaped fixing elements) and adhesive bonding (through the adhesive layer on the label portions) into a single integrated fastening system. This combination provides both structural complexity for anti-rotation stability and chemical bonding for secure attachment, achieving superior performance without requiring multiple separate components.
Solution Approach 2:
The fastening system utilizes a composite approach by combining the adhesive label material with the comb-like structural elements and adhesive layer. This composite structure integrates different functional characteristics: the label provides adhesive bonding, while the comb structure provides mechanical interlocking and anti-rotation capability, achieving both simplicity and stability.
3Reliability
If the adhesive label uses a comb-like structure with multiple fixing elements, then the fixation reliability is improved, but the device complexity increases
Solution Approach 1:
The adhesive label is designed as a flexible thin film structure that can be easily applied to the container surfaces. The comb-like structure is integrated into this flexible film, allowing it to conform to the container geometry while providing multiple fixing elements. This flexible film approach maintains simplicity in application and handling while achieving reliable fixation through the distributed comb structure.

AI summary
An adhesive label for a multi-part container having a threaded member and a container body includes a first, sheet-like label portion adapted to be attached to the threaded member of the container, and a second label portion adjacent the first label portion and adapted to be attached to the container body of the container. The second label portion has a comb-like structure with strip-shaped fixing elements such that the adhesive label couples the threaded member to the container body relative to a condition applied to the container and opposes movement of the threaded member relative to the container body.
