Adhesive Tape Cut Trigger for Tool-Free Box Unsealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for unsealing boxes sealed with adhesive tape often require tools, risk damage to contents, or are difficult to execute, especially when unintentional forces are applied, leading to potential injury or unintended unsealing during transportation.
Innovation Solution
A method and device that form a cut on the adhesive tape at a specific location near the mating portion, using a tool or device with a roller and guide to create a trigger cut that can be easily extended with minimal force, allowing for tool-free unsealing without damaging the contents or inadvertently opening the box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive tape is used to seal the box, then sealing ability is improved, but unsealing becomes difficult and may require tools
Solution Approach 1:
A cut line is formed on the box at a predetermined position before the adhesive tape is applied. This preliminary cut line serves as a guide for subsequent unsealing operations, allowing the adhesive tape to be easily peeled off along the marked line without requiring tools or excessive force.
2Ease of operation
If the adhesive tape is peeled off strongly to unseal the box, then unsealing is achieved, but the nail may be damaged
Solution Approach 1:
The cut line is pre-formed on the box to provide a designated path for peeling the adhesive tape. This allows the unsealing process to proceed with minimal force applied along the cut line, preventing concentrated stress that could damage the nail while still achieving effective unsealing.
3Ease of operation
If the cut line is formed on the box, then adhesive tape can be easily peeled off, but the outer liner is peeled off together with the adhesive tape
Solution Approach 1:
The cut line is formed at a specific location on the box where the outer liner and adhesive tape can be separated. By positioning the cut line strategically, the adhesive tape can be peeled off independently without removing the outer liner, preserving the box's sealing capability for future use.
4Manufacturing precision
If the adhesive tape is adhered carefully to the correct position, then sealing precision is improved, but the work becomes more time-consuming
Solution Approach 1:
The cut line is pre-formed on the box at the correct position before adhesive tape application. This preliminary marking serves as a visual guide during tape application, ensuring accurate positioning without requiring careful measurement or adjustment, thereby reducing the time needed for proper tape placement.
Data Source
AI summary
A box sealed by fixing a surrounding area of a mating portion of outer flaps and an end face plate by an adhesive tape made of a film as a base material. Information showing a forming position of a cut to function as a trigger to unseal the box is preliminarily indicated on the box. According to the information, the cut is formed on the adhesive tape only at a portion facing to the mating portion in a state that the outer flaps are sealed.
