Multi-compartment Packaging Segmentation for Freshness

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional single compartment packaging for bulk or economy sizes exposes the entire contents to air and moisture upon opening, leading to spoilage and staleness, especially in products that lose potency or freshness quickly.

Innovation Solution

A multi-unit storage device with two separate compartments joined in a way that accessing one compartment does not compromise the product in the other compartment, allowing for independent sealing and access, and featuring perforations for easy detachment when one compartment is depleted.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If single compartment packaging is used for bulk or economy sizes, then packaging cost and complexity are reduced, but the entire contents are exposed to air and moisture upon opening leading to spoilage and staleness

Engineering Contradiction:

Improvepackaging structureVSAvoidexposure to air and moisture

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The packaging is divided into multiple compartments that are sealed together. Each compartment contains a portion of the product and can be opened independently. When one compartment is opened, the other compartments remain sealed and protected from air and moisture exposure, thus resolving the contradiction between simple packaging structure and protection from harmful factors.

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If bulk or economy size packaging is used, then cost savings per serving are achieved, but product spoilage and staleness increase due to prolonged exposure to air

Engineering Contradiction:

Improveproduct quantityVSAvoidproduct freshness

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The bulk product is segmented into multiple sealed compartments. This allows consumers to purchase economy sizes while only exposing one compartment at a time to air, maintaining product freshness and reliability throughout the usage period.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The compartments are pre-sealed at the factory in a controlled environment. This preliminary sealing action protects the product from air exposure until the moment of consumer use, ensuring freshness is maintained throughout storage and usage.

Inventive Principle:

Principle #10Preliminary action

3Object-generated harmful factors

If preservatives are removed from products, then product safety and health benefits are improved, but susceptibility to spoilage and staleness upon air exposure increases

Engineering Contradiction:

Improvepreservative contentVSAvoidspoilage and staleness

Core Design Contradiction:

Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

By segmenting the product into separately sealed compartments, the packaging compensates for the removal of preservatives. Each compartment remains protected from air until opened, reducing susceptibility to spoilage and staleness even without chemical preservatives.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent converts the potential harm of removed preservatives into a benefit by using physical barriers (sealed compartments) instead of chemical preservation. The sealed environment replaces the protective function previously provided by preservatives.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

Described herein are multi-unit storage devices where two separate compartments are joined in a manner such that accessing one of the compartments does not compromise product held in the other compartment. The separate compartments may be vacuum or otherwise sealed such that when the seal is broken, access to the products contained therein is provided. Each of the compartments may be independently sealed.
