Resealable Inner Package With Hinged Lid And Flap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Access to consumer goods within hinge-lid containers can be challenging due to partial coverage of the extraction opening by a cover flap, and grasping goods is difficult as the opening is typically limited to the front and top sides, not the back.
Innovation Solution
A container design with a hinged connector connecting the lid to the back wall, featuring an inner package with a flap that separates from the lid to uncover the access opening from multiple sides, allowing easier access and resealing, and an inner frame for structural reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover flap is used to close the extraction opening of the inner package, then the airtight seal is improved, but the access to consumer goods is restricted and difficult to grasp from multiple sides
Solution Approach 1:
The patent divides the inner package structure into separate components: the rigid cup-shaped container, the flexible lid, and the cover flap. The extraction opening is segmented to allow the lid to be peeled away partially, exposing the goods while the cover flap remains attached to seal the opening. This segmentation enables both airtight sealing and easy access from multiple sides.
Solution Approach 2:
The lid is designed as a flexible, removable component that can be dynamically adjusted. Users can peel the lid away to the extent needed to access goods, while the cover flap remains attached to the rigid container to maintain the seal. This dynamic structure resolves the contradiction between maintaining a seal and enabling access.
2Ease of manufacture
If the extraction opening is limited to front and top sides only, then the manufacturing complexity is reduced, but the usability and access to goods are compromised
Solution Approach 1:
The rigid cup-shaped container with its open top design serves multiple functions: it provides structural support, defines the extraction opening geometry, and allows access from multiple sides (front, top, and back). The cover flap universally seals the opening regardless of the access direction, making the package usable from any side while maintaining manufacturing simplicity.
3Stability of the object's composition
If the inner package is permanently affixed to the rigid container, then the structural stability is improved, but the ability to reseal after opening is lost
Solution Approach 1:
The cover flap acts as an intermediary element between the rigid container and the flexible lid. It remains permanently attached to the rigid container via adhesive, providing structural stability, while the flexible lid can be removed and reattached. This intermediary structure enables the package to be opened and resealed multiple times while maintaining overall structural integrity.
4Shape
If a hinged connector is used to connect the lid to the back wall, then the lid positioning is improved, but the device complexity increases
Solution Approach 1:
The hinged connector merges the lid attachment function with the back wall structure. By integrating the hinge mechanism into the back wall of the rigid container, the design achieves precise lid positioning and alignment without adding separate, complex positioning components. This merging reduces overall device complexity while maintaining proper lid geometry and positioning.

AI summary
A container includes a housing that has a box and a lid, where the box includes a front wall and a back wall. A hinged connector is connected to the lid at a first hinge line and connected to the back wall of the box at a second hinge line. The container also includes an inner package disposed within the housing. The inner package includes a first layer that defines a flap and a second layer at least partially attached to an inner surface of the first layer, where the second layer defines an access opening through which the consumer goods can be removed. The lid is movable between a closed position and an open position. The inner package is covered by the lid and the box when the lid is in the closed position and at least partially uncovered when the lid is in the open position.
