Sliding Container Locking Mechanism for Inadvertent Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for consumer goods, such as aerosol generating articles, often face issues with lids inadvertently opening during transport, leading to potential damage or loss of freshness due to accidental exposure.
Innovation Solution
A container design featuring an outer sleeve and a slidable inner box with a locking mechanism, where the inner box engagement flap engages with a corresponding element on the outer sleeve back wall, preventing unintended opening, and a release element allows controlled access, minimizing visual impact and maintaining container integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inner box is made slidable within the outer sleeve for easy access, then ease of operation is improved, but the risk of inadvertent opening increases
Solution Approach 1:
The locking mechanism is engaged in advance during assembly, preventing the inner box from sliding out unintentionally. The engagement flap is positioned to automatically lock with the sleeve, ensuring the container remains secure during transport before the user intentionally activates the release mechanism.
Solution Approach 2:
The engagement flap acts as an intermediary element between the inner box and outer sleeve. This flap provides a controlled interface that allows the box to be locked securely while still enabling intentional access through the release element, mediating between the conflicting needs of security and accessibility.
2Ease of operation
If the locking mechanism is made visible for user interaction, then ease of operation is improved, but the aesthetic appearance deteriorates
Solution Approach 1:
The release element is extracted as a separate, discrete component that can be positioned strategically on the container. This allows the functional element to be minimized and placed in a location that has the least impact on the overall aesthetic design, while still being accessible to users who need to open the container.
3Ease of manufacture
If the engagement flap structure is simplified for manufacturing, then ease of manufacture is improved, but the locking reliability may worsen
Solution Approach 1:
The locking mechanism is segmented into distinct functional elements: the engagement flap on the inner box and the corresponding engagement structure on the outer sleeve. This segmentation allows each component to be manufactured separately using standard processes, then assembled together to form a reliable locking system that is both simple to manufacture and effective in function.

AI summary
A container (1) for consumer goods, the container comprises an outer sleeve (20) and inner box (10) disposed within the outer sleeve (20), and configured to be slidable with respect to the outer sleeve (20) between: a first position, in which the interior of the inner box (10) cannot be accessed by a user; and a second position, in which the interior of the inner box (10) can be accessed by a user. The container (1) having a locking mechanism for preventing the inner box (10) from sliding from the first position to the second position, when the inner box (10) is in the first position in the outer sleeve (20).
