Removable Sealing Strip With Folded Tab For Container Lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing methods for containers, such as those using adhesive sealing labels, are difficult to remove once applied, making it challenging to initially open the container without damaging the seal.
Innovation Solution
A removable sealing strip with a foldable design and strategically placed adhesive, featuring indicia to guide users in folding and applying the strip, allowing for easy attachment and detachment from the container lid and body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high adhesive bond is used to seal the lid and container body, then the sealing effectiveness is improved, but the ease of removal deteriorates
Solution Approach 1:
The sealing strip is divided into three portions: a first portion with high-adhesive material for sealing to the container body, a second portion with low-adhesive material for easy removal, and a third portion serving as a tab. This segmentation allows different adhesive properties in different regions, achieving both strong sealing and easy removal.
Solution Approach 2:
Different adhesive properties are applied to different portions of the sealing strip. The first portion uses high-adhesive material (adhesive force ≥10 N) for strong bonding to the container body, while the second portion uses low-adhesive material (adhesive force <5 N) for easy removal, creating local quality variations that resolve the contradiction between sealing effectiveness and ease of removal.
2Ease of operation
If a removable bonding between the first and second portions is used, then the ease of removal is improved, but the sealing stability deteriorates
Solution Approach 1:
The bonding between the first and second portions is segmented into different adhesive materials with distinct properties. The first portion uses strong adhesive for stable sealing, while the second portion uses weak adhesive for easy removal, maintaining both stability and removability through segmentation.
Solution Approach 2:
The bonding characteristics are made dynamic rather than uniform: the first portion maintains strong bonding for sealing stability, while the second portion allows easy separation. This dynamic differentiation of adhesive properties resolves the contradiction between sealing stability and ease of removal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The sealing strip effectively seals the container while being easily removable, simplifying the opening process and reducing manufacturing costs.
Implementation Method 1
An adhesive is disposed on the inner surface of the first, second and third portions of the strip. The adhesive on the inner surface of the third portion of the strip is configured to attach to and interconnect the lid to the top portion of the container
Implementation Method 2
The strip, when removed from the substrate, is foldable along the fold line such that the inner surface of the first portion of strip is configured to be bound to inner surface of the second portion of strip

AI summary
A removable sealing strip and method is provided for sealing a lid removably secured to a top portion of a container. The removable sealing strip includes a strip removably affixed to a substrate and has a first portion extending from a first end thereof, a second portion extending from the first portion, and a third portion extending between the second portion of the strip and a second end thereof. The strip is foldable along a fold line such that an inner surface of the first portion of strip binds to an to inner surface of the second portion of the strip so as to define a tab on the strip. The inner surface of the third portion of the strip is affixable to the lid and to the top portion of the container to substantially inhibits removal of the lid from the top portion of the container. The tab is configured to facilitate removal of the third portion of the strip from the lid and the top portion of the container.
