Solution Overview

Problem

Existing packaging systems with child-resistant features often have structurally weak outer sleeves that can be compromised by children, leading to unintended access to medication, and their manufacturing processes are inefficient and cumbersome.

Innovation Solution

A packaging system with an improved false end wall design that is easily formed and secured within the outer sleeve, providing structural integrity and preventing manipulation without using the release mechanism, and can be efficiently constructed using automated processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a false end wall is added to provide structural support, then child resistance is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvechild resistanceVSAvoidmanufacturing process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The false end wall is integrated into the blank structure during manufacturing, combining the false end wall formation with the outer sleeve construction into a single integrated process. This eliminates the need for separate assembly steps and reduces manufacturing complexity while maintaining the structural support function.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The false end wall is pre-formed as part of the blank structure before the outer sleeve is assembled. By preparing the false end wall in advance during blank fabrication, the need for complex post-assembly operations is eliminated, simplifying the overall manufacturing process.

Inventive Principle:
Principle #10Preliminary action

2Strength

If multiple folding sequences are used to form the false end wall, then structural integrity is improved, but manufacturing time increases

Engineering Contradiction:
Improvestructural integrityVSAvoidmanufacturing time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

Multiple folding operations that previously required separate sequential steps are merged into a single coordinated folding sequence. The blank is designed with fold lines and panel arrangements that allow simultaneous formation of the false end wall and outer sleeve structure in one continuous operation, reducing manufacturing time while maintaining structural integrity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The blank is divided into specific panels with predetermined fold lines that enable the false end wall to be formed through a simplified folding sequence. By segmenting the blank into functional panels (front panel, back panel, side panels, false end wall panels), the folding process becomes more efficient and can be executed in fewer steps.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If specialized machinery is used to form the false end wall, then manufacturing precision is improved, but equipment complexity increases

Engineering Contradiction:
Improvefalse end wall formation precisionVSAvoidmachinery complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The false end wall formation is merged with standard straight-line folding and securing operations that can be performed by conventional packaging machinery. The blank design incorporates features that work with existing equipment capabilities, eliminating the need for specialized machinery while maintaining manufacturing precision through proper panel geometry and fold line placement.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A package includes a slide card that is received in an outer sleeve having a false end wall. The false end wall extends between a top wall and a bottom wall to enhance the structural integrity of the outer sleeve. The false end wall provides child resistance in that it prevents a user from manipulating the outer sleeve to inadvertently disengage a locking feature that lockably retains a slide card in the outer sleeve. The false end wall also prevents a user from accessing the slide card through an opening that is created by removing an end wall.
