Multi-Compartment Package with Re-Closable Seals for Freshness

Solution Overview

Problem

Existing packages do not effectively maintain the freshness and flavor of consumer products by preventing exposure to ambient air, leading to flavor scalping and degradation.

Innovation Solution

A multi-compartment package design with re-closeable seals and tear-points allows for selective access to compartments, featuring a foldable configuration that includes compartments with different durations for product consumption and a gas/moisture-impermeable layer to minimize exposure to ambient air.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If a single-compartment package is used, then the structure is simple, but the product freshness cannot be maintained for extended periods

Engineering Contradiction:

Improveshelf lifeVSAvoidpackage structure

Core Design Contradiction:

Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The package is divided into multiple compartments (first compartment, second compartment, third compartment) that can be opened and closed independently. Each compartment can be accessed through its own re-closeable seal, allowing selective opening without exposing the entire package contents to ambient air, thereby extending shelf life while maintaining manageable structural complexity through modular design

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If the package is made completely impermeable, then flavor scalping is prevented, but the product cannot be accessed

Engineering Contradiction:

Improveflavor scalpingVSAvoidproduct access

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

Re-closeable seals are pre-installed on each compartment, allowing the package to be opened for product access and then securely closed to prevent flavor scalping. The tear-points are pre-positioned to enable easy initial opening without compromising the seal integrity, balancing accessibility with protection against ambient air exposure

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The package employs gas/moisture-impermeable layers in specific locations (between compartments and at seal areas) rather than making the entire package impermeable. This localized application maintains product freshness and prevents flavor scalping while allowing controlled access points through the re-closeable seals, resolving the contradiction between complete protection and ease of operation

Inventive Principle:

Principle #3Local quality

3Reliability

If multiple compartments are added, then product freshness is maintained, but the package complexity increases

Engineering Contradiction:

Improvefreshness maintenanceVSAvoidpackage structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The package is divided into multiple compartments (first compartment, second compartment, third compartment) that can be opened and closed independently. Each compartment can be accessed through its own re-closeable seal, allowing selective opening without exposing the entire package contents to ambient air, thereby extending shelf life while maintaining manageable structural complexity through modular design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The package utilizes a nested structure where the first, second, and third compartments are arranged within an outer package. The compartments can be folded onto each other in a compact configuration, with the gas/moisture-impermeable layers nesting between compartments. This nested arrangement maintains freshness through multiple barriers while minimizing the overall package footprint and reducing structural complexity

Inventive Principle:

Principle #7Nested doll (Nesting)
