Paper Slip Stack Packaging With Pull-Tab Tear Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging methods for paper slip stacks are cumbersome, as they require cutting the packaging sheet, making it difficult to maintain the stack's order during refilling and can lead to disarrangement, and the uppermost slip must protrude for easy removal, complicating the process.
Innovation Solution
A packaging system using a synthetic-resin film or shrink film with a tab and perforation lines allows for easy removal of the packaging sheet by pulling a tab, maintaining the stack's order and facilitating insertion and removal from a paper holder without cutting, using a fragile cutting part that can be torn with minimal force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the packaging sheet is cut with scissors to remove it, then the paper slip stack can be accessed, but the paper slip stack may slip out of hand and become disarranged
Solution Approach 1:
The packaging sheet is segmented into a main body and a tab portion that can be pulled separately. The tab is formed by folding back a portion of the packaging sheet and adhering it to itself, creating a dedicated pulling element that allows users to remove the packaging without directly handling the paper slip stack, thus preventing disarrangement while enabling easy removal.
2Stability of the object's composition
If the packaging sheet is made secure to hold the paper slip stack, then the stack remains stable, but the packaging sheet becomes difficult to remove
Solution Approach 1:
The packaging sheet is divided into a stable main body that secures the paper slip stack and a separate tab portion that facilitates removal. The tab is formed by folding back and adhering a portion of the packaging sheet, creating a dedicated pulling element that allows easy removal without compromising the overall security of the bundled paper slip stack during storage and handling.
3Volume of moving object
If the uppermost paper slip does not protrude, then the packaging is compact, but it becomes difficult to pull the paper slip out of the holder
Solution Approach 1:
The tab serves as an intermediary element that connects the user's pulling action to the paper slip stack. When the tab is pulled, it gradually releases the packaging sheet from the paper slip stack, allowing the uppermost paper slip to emerge from the holder without requiring it to protrude beforehand. This mediator mechanism enables easy paper slip removal while maintaining a compact package structure.

AI summary
There is provided a package for paper slip stack, which can steadily and stably store the paper slip stack bundled by a packaging sheet and being easily released from the packaging sheet after being contained in a paper holder. The paper slip stack is formed by alternately interlocking half parts 5a and 5b of twofold paper slips 5 with one another oppositely in their folded directions so as to stack the paper slips 5 in piles in their mutually interconnected state and bundled by a packaging sheet 3 which is provided with a tab 4 protruding outward from one side opposite to either of upper or lower surfaces of the paper slip stack 2 and a fragile cutting part 7 formed anywhere in a longitudinal direction of the packaging sheet 3 so as to be cut by a tensioning force produced by pulling the aforesaid tab 4.
