Tamper-Evident Header with Displaceable Segment for Slider Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reclosable packaging solutions with zipper closures and slider devices lack efficient accessibility and display/transport capabilities, particularly in ensuring limited access to the combined closure while maintaining tamper evidence and convenience.
Innovation Solution
A reclosable package design featuring a tamper-evident header with a displaceable segment that allows access to the slider device, combined with a hang hole or handle for enhanced display and transport, where the segment is either completely removable or partially severable to facilitate easy access and resealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tamper-evident header completely surrounds the slider device, then tamper evidence is maintained, but access to the slider device becomes difficult
Solution Approach 1:
The tamper-evident header is divided into a fixed portion and a displaceable segment. The fixed portion remains attached to the package to maintain tamper evidence, while the displaceable segment can be moved or removed to allow access to the slider device. This segmentation resolves the contradiction by separating the tamper evidence function from the access function.
Solution Approach 2:
The header transitions from a static completely-surrounding structure to a dynamic structure with a displaceable segment. The segment can be moved from its initial position covering the slider to a displaced position that allows access, while the fixed portion maintains the tamper evidence indication. This dynamic capability allows the header to adapt between protecting and accessing the slider.
2Reliability
If the tamper-evident header is made fully secure and sealed, then tamper evidence is enhanced, but the package becomes harder to handle and display
Solution Approach 1:
The header is segmented into a fixed portion that provides tamper evidence and a displaceable segment that can be moved for handling. The fixed portion maintains security while the displaceable segment can be configured to allow hanging or carrying operations.
Solution Approach 2:
The tamper-evident header structure serves multiple functions: it provides tamper evidence through the fixed portion, allows access to the slider through the displaceable segment, and enables hanging or carrying when the segment is in its displaced position. This multi-functionality resolves the contradiction by making the header adaptable to different operational requirements.

AI summary
A reclosable package includes first and second side panels connected to each other along respective side edges and bottom edges. A zipper closure is secured to the first and second side panels along upper edges thereof. A slider device is operably mounted on the zipper closure for opening and closing the zipper closure and a tamper-evident header is connected to the zipper closure and surrounds the slider device. The tamper-evident header has a front portion and a rear portion with upper ends connected together above the slider device and lower ends connected to the zipper closure. The front portion includes a segment displaceable therefrom to allow access to the slider device. A rear portion of the header may be formed with a hole for suspending or carrying the package.
