Pouch Package with Segmented Compartments and Seals

Solution Overview

Problem

Conventional packaging solutions fail to maintain the freshness of commodities like hand-rolled tobacco after the package is opened, as they do not provide a hermetic seal, leading to moisture loss and deterioration.

Innovation Solution

A pouch package design featuring multiple compartments with a combination of permanent and temporary seals, including peelable and resealable adhesive seals, allows for hermetic sealing and easy access while maintaining freshness by minimizing exposure to air.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a hermetically sealed package is used to maintain freshness, then the commodity remains fresh longer, but the package cannot be easily opened and resealed

Engineering Contradiction:

Improvefreshness maintenanceVSAvoidopening and resealing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The package is divided into multiple compartments separated by partition walls, with each compartment having its own temporary seal. This allows selective opening of individual compartments while maintaining hermetic sealing in others, resolving the contradiction between freshness maintenance and ease of operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The package incorporates both permanent seals (for hermetic sealing) and temporary seals (for easy opening and resealing). The temporary seals can be repeatedly opened and closed, providing dynamic functionality that adapts to different usage stages, while permanent seals maintain the hermetic barrier.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a single compartment design is used, then the package structure is simpler, but the commodity cannot be selectively accessed without exposing all contents to air

Engineering Contradiction:

Improveselective accessVSAvoidpackage structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The package is divided into multiple compartments separated by partition walls, with each compartment having its own temporary seal. This allows selective opening of individual compartments while maintaining hermetic sealing in others, resolving the contradiction between freshness maintenance and ease of operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the package (compartments) have different sealing characteristics - some compartments may have permanent seals for long-term storage, while others have temporary seals for frequent access. This local differentiation allows optimized functionality for different product types within the same package structure.

Inventive Principle:

Principle #3Local quality

3Reliability

If permanent seals are used along all edges, then the package provides complete hermetic sealing, but the package cannot be opened for access

Engineering Contradiction:

Improvehermetic sealingVSAvoidopenability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The package is divided into multiple compartments separated by partition walls, with each compartment having its own temporary seal. This allows selective opening of individual compartments while maintaining hermetic sealing in others, resolving the contradiction between freshness maintenance and ease of operation.

Inventive Principle:

Solution Approach 2:

The package incorporates both permanent seals (for hermetic sealing) and temporary seals (for easy opening and resealing). The temporary seals can be repeatedly opened and closed, providing dynamic functionality that adapts to different usage stages, while permanent seals maintain the hermetic barrier.

AI summary

A package in the form of a pouch comprises a first flexible sheet part 6 and a second flexible sheet part 7. The pouch comprises a first permanent seal 14 between the first sheet part 6 and the second sheet part 7 along a first edge 12 of the pouch. The pouch comprises a second permanent seal 15 between the first sheet part 6 and the second sheet part 7 along a second edge 13 of the pouch opposite to the first edge 12. The pouch comprises a first temporary seal 16 between the first sheet part 6 and the second sheet part 7, the first temporary seal 16 extending across the pouch between the first permanent seal 14 and the second permanent seal 15. The pouch comprises a second temporary seal 17 between the first sheet part 6 and the second sheet part 7, the second temporary seal 17 extending across the pouch between the first permanent seal 14 and the second permanent seal 15. The pouch comprises a first compartment 20 bounded by the first sheet part 6, the second sheet part 7, the first permanent seal 14, the second permanent seal 15 and the first temporary seal 16 and a second compartment 21 bounded by the first sheet part 6, the second sheet part 7, the first permanent seal 14, the second permanent seal 15, the first temporary seal 16 and the second temporary seal 17.
