Packaging Container With Peelable Membrane Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging containers for bulk solids do not adequately protect the quality of goods during transport, storage, and dispensing, as they lack effective compartmentalization and sealing mechanisms to prevent contamination and exposure to air and moisture.
Innovation Solution
A packaging container with a container body having a series of peelable or tearable sealing membranes that form inner compartments, allowing for separate storage and protection of bulk solids, with gastight options to maintain freshness and reduce packaging material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a single large packaging container is used for bulk solids, then packaging material usage is reduced, but the quality protection and freshness of the bulk solids deteriorate due to prolonged exposure to air and moisture
Solution Approach 1:
The packaging container is divided into multiple inner compartments separated by peelable or tearable sealing membranes. Each compartment can be accessed independently, allowing consumers to use the bulk solids in one compartment without exposing the others to air and moisture. This segmentation maintains quality protection while using a single container structure.
2Reliability
If multiple inner compartments are introduced to improve quality protection, then the reliability of quality protection is improved, but the device complexity increases due to additional sealing membranes and compartment structures
Solution Approach 1:
Peelable or tearable sealing membranes are used to separate inner compartments instead of rigid dividers. These thin film structures provide effective sealing and protection while maintaining relative structural simplicity and ease of manufacturing.
3Ease of operation
If the entire container is opened to access bulk solids, then ease of operation is improved, but the loss of substance increases due to exposure of all contents to air and moisture
Solution Approach 1:
The container is segmented into multiple sealed compartments. Consumers can open only the specific compartment they need without exposing other compartments to air and moisture, thereby maintaining product freshness and reducing loss of substance while preserving ease of operation.
4Strength
If traditional rigid packaging is used, then strength and protection during transport are improved, but the ability to maintain freshness and reduce packaging material usage deteriorates
Solution Approach 1:
The rigid packaging container is divided into multiple inner compartments with peelable or tearable sealing membranes. This allows the container to maintain structural strength for transport protection while enabling selective access to compartments, thereby maintaining freshness of unused portions.
Solution Approach 2:
Peelable or tearable sealing membranes are integrated into the rigid container structure. These flexible thin film barriers provide effective sealing to maintain freshness while allowing easy opening when needed, combining the advantages of both rigid and flexible packaging.

AI summary
The present invention provides a packaging container for bulk solids. The container comprises a container body having a container wall extending from a container bottom to a container opening in a height direction of the container. The container wall and the container bottom delimit an inner space in the container, and a first peelable or tearable sealing membrane being attached to an inner surface of the container wall forms a roof over a first inner compartment in the inner space. A second peelable or tearable sealing membrane is applied between the first peelable or tearable sealing membrane and an edge of the container opening and is attached to the inner surface of the container wall. The first peelable or tearable sealing membrane forms a floor of a second inner compartment in the inner space and the second peelable or tearable sealing membrane forms a roof over the second inner compartment.
