Tampon Applicator Wrapper with Partial Tear Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tampon and applicator wrappers are difficult to open and often result in small, separate pieces of wrapper that are hard to manage and dispose of hygienically.
Innovation Solution
A wrapper design with strategically placed lines of weakness, such as perforations, allows for easy opening while maintaining the wrapper as a single piece, enabling the tampon and applicator assembly to be removed and then reused to hygienically wrap and discard the used applicator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a serrated edge is provided in the wrapper, then multiple tearing points are provided for opening the wrapper, but small pieces of the wrapper are separated from the wrapper making it difficult to manage and dispose of hygienically
Solution Approach 1:
The wrapper is divided into two functional zones: a tearable zone with a tear strip containing serrated edges for easy opening, and a non-tearable zone that maintains structural integrity. This segmentation allows the wrapper to be opened easily while preserving the main body for hygienic disposal of the used applicator.
Solution Approach 2:
Different portions of the wrapper have different properties: the tear strip portion has serrated edges that facilitate tearing, while the remaining wrapper maintains full integrity. This local differentiation of properties allows the wrapper to serve dual purposes: easy opening and intact disposal.
2Ease of operation
If a tear strip extending the length of the wrapper is provided, then the wrapper can be opened by pulling the tab, but the wrapper is completely torn open along its length requiring separate disposal of the applicator and wrapper
Solution Approach 1:
The tear strip is segmented to extend only partially along the wrapper rather than its full length. This partial segmentation allows the wrapper to be opened sufficiently to remove the applicator while leaving the majority of the wrapper intact for combined disposal with the applicator.
3Reliability
If conventional wrapper designs are used, then the tampon and applicator can be enclosed and protected, but the wrapper becomes difficult to open or results in separate pieces that are hard to dispose of hygienically
Solution Approach 1:
The wrapper is pre-configured with a tear strip and serrated edges during manufacturing, preparing the opening mechanism in advance. This preliminary action ensures that the wrapper maintains full protective integrity until use, at which point the pre-prepared tear features enable easy and clean opening without compromising hygienic protection.

AI summary
A package includes a tampon and applicator assembly and a wrapper for enclosing the tampon and applicator assembly. The wrapper is selectively configurable between a sealed configuration wherein the tampon and applicator assembly are sealingly enclosed in the wrapper and an opened configuration for allowing the tampon and applicator assembly to be removed from the wrapper. The wrapper has a front panel, a back panel, two side edges, two end edges, an interior space, a longitudinal axis, and a transverse axis. The front panel has, in the opened configuration of the wrapper, a pair of spaced-apart longitudinal components extending generally parallel to each other and longitudinally of the wrapper to define an opening in the wrapper. Each of the longitudinal components is spaced inward from the respective side edge.
