Solution Overview

Problem

Current security packages made of paperboard are difficult to open and re-close, making them unusable for storage after initial use, and they often become damaged, rendering them unsuitable for resale.

Innovation Solution

A two-piece blister package design featuring a stationary inner blister and a rotatable outer blister, allowing for secure opening and re-closure, using tear-resistant paperboard materials like NATRALOCK®, with a mechanism that allows the outer blister to rotate and align with detents for secure closure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a security package is made of tear-resistant paperboard to prevent theft and tampering, then security and sustainability are improved, but the package becomes difficult to open and cannot be easily re-closed for storage or resale

Engineering Contradiction:
ImprovesecurityVSAvoidopenability and re-closability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The package is divided into two separate components: a stationary base portion and a rotatable blister portion. This segmentation allows the package to maintain security through its robust paperboard construction while enabling easy opening and re-closing through the rotatable mechanism. The blister portion can be rotated to access contents and then rotated back to reclose, solving the contradiction between security and ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The package incorporates a dynamic rotatable mechanism that transitions between locked and open states. The blister portion rotates on a pivot point, allowing it to move from a closed secure position to an open access position and back again. This dynamic feature enables multiple open/close cycles while maintaining the security integrity of the paperboard construction, resolving the contradiction between security and re-closability.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a blister package requires a tool such as scissors or knife to open, then security is improved, but the package becomes damaged and unusable for future storage or resale

Engineering Contradiction:
ImprovesecurityVSAvoidreusability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The rotatable blister mechanism provides a dynamic opening method that does not require cutting tools. The blister portion simply rotates to open, maintaining the integrity of the paperboard package. After use, the blister can be rotated back to reclose the package, preserving it for future storage or resale, thus resolving the contradiction between security and reusability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The design allows the package to be recovered and reused after opening. Unlike traditional security packages that are damaged during opening, this rotatable mechanism preserves the package structure, allowing it to be recovered for continued use as storage or for resale as returned goods, solving the contradiction between security and reusability.

Inventive Principle:
Principle #34Discarding and recovering

3Loss of substance

If a package is made primarily of paperboard for sustainability, then environmental impact is reduced, but the package lacks the durability and re-closability needed for ongoing storage use

Engineering Contradiction:
ImprovesustainabilityVSAvoidre-closability
Core Design Contradiction:
Loss of substanceVSEase of operation

Solution Approach 1:

The package separates the sustainability function (paperboard base) from the operational function (rotatable blister mechanism). This segmentation allows the paperboard to provide sustainable packaging while the rotatable mechanism provides easy re-closability, resolving the contradiction between sustainability and ease of operation for ongoing storage use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dynamic rotatable mechanism enables the sustainable paperboard package to be easily opened and re-closed multiple times. This dynamic feature adds functionality to the sustainable package design, allowing it to be reused for storage without compromising the environmental benefits, thus resolving the contradiction between sustainability and re-closability.

Inventive Principle:
Principle #15Dynamics

AI summary

A package is disclosed comprising an outer blister portion and an inner blister portion, each blister portion having a flange, the flanges enclosed between paperboard cards, arranged so that upon rotation of the outer blister portion access is obtained to compartments within the inner blister portion. The compartments may hold product items.
