Container Lid Finger Application Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers with lid-opening mechanisms are difficult to identify by sight or feel, especially in dim environments, and lack distinct external characteristics, making it hard to distinguish authentic from imitation products, and they often require specific fingertip placement for easy operation, which can lead to deformation or difficulty in opening.
Innovation Solution
A container design featuring a wave-like finger application part protruding from the front edge of the lid, formed by a break line and fold line, which allows easy identification of the lid opening edge by sight or feel, and provides a distinct external characteristic to prevent imitation, while ensuring easy insertion and opening of the lid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a finger groove or cutout portion is added to the insertion part to identify the opening edge, then the ease of operation is improved, but the device complexity increases and requires specific fingertip placement
Solution Approach 1:
The finger application part is formed with a wave-like shape that protrudes from the front wall, creating a localized distinct feature at a specific location. This local quality modification allows users to easily identify the opening edge by sight or feel without requiring complex structures throughout the entire container.
Solution Approach 2:
The finger application part is positioned asymmetrically on the front edge of the lid, creating a unique visual and tactile characteristic that distinguishes the opening edge. This asymmetric design makes it immediately recognizable to users while maintaining simplicity in the overall container structure.
2Ease of manufacture
If the front edge of the lid sinks in from the opening face to simplify the structure, then the ease of manufacture is improved, but the reliability deteriorates causing deformation of contained products
Solution Approach 1:
The finger application part is formed with a wave-like shape that protrudes from the front wall, creating a localized distinct feature at a specific location. This local quality modification allows users to easily identify the opening edge by sight or feel without requiring complex structures throughout the entire container.
Solution Approach 2:
The finger application part is pre-formed to protrude from the front wall during the manufacturing process, providing a ready-made reference point for users. This preliminary action eliminates the need for users to search for the opening edge or apply force to a sinking lid edge, thereby preventing product deformation while maintaining manufacturing simplicity.
3Ease of operation
If a finger groove and cutout portion are formed to enable easy opening, then the ease of operation is improved, but the container becomes easily imitated lacking distinct external characteristics
Solution Approach 1:
The finger application part is positioned asymmetrically on the front edge of the lid, creating a unique visual and tactile characteristic that distinguishes the opening edge. This asymmetric design makes it immediately recognizable to users while maintaining simplicity in the overall container structure.
Solution Approach 2:
The wave-like shape of the finger application part creates a distinct visual pattern that can be easily perceived by sight or feel. This visual differentiation serves as a unique identifier that is difficult for imitators to replicate, thereby protecting against product counterfeiting while maintaining ease of operation.

AI summary
The container of the present invention is provided with a box body 1 having front and rear walls 4 and 5, left and right walls 6, and a bottom wall 7; a lid 2 continuous with the rear wall 5; and an insertion part 3 continuous with the front edge of the lid 2. A plurality of finger application parts 20 is integrally connected to the front edge of the lid 2 at at least one second connecting portion of the lid. With the insertion part 3 inserted in the inner face of the front wall 4, the finger application parts 20 protrude frontward from the front wall 4, so by applying fingertips to the finger application parts 20, it is possible to conveniently insert or remove the insertion part 3 and open or close the lid 2.
