Food Container Lid Audible Tactile Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers with lids for food products lack effective audible and tactile feedback mechanisms to ensure full engagement and prevent spoilage, as they often require special configurations for sound production and do not consistently provide reassurance of proper sealing.
Innovation Solution
A container and lid design featuring an annular ring on the neck and an engagement mechanism with protrusions and recesses on the lid, which produce audible and tactile feedback upon full engagement, ensuring secure sealing and user confirmation of proper closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard container necks are used without special configurations, then manufacturing simplicity is maintained, but audible and tactile feedback for full engagement is not provided
Solution Approach 1:
The engagement confirmation function is segmented into two independent components: an annular ring attached to the container neck and an engagement mechanism on the lid. This segmentation allows the feedback mechanism to be added to standard containers without redesigning the entire container structure, maintaining manufacturing simplicity while providing reliable engagement confirmation through audible and tactile feedback when the lid is fully engaged.
Solution Approach 2:
The annular ring serves as an intermediary element between the container neck and the lid's engagement mechanism. It mediates the interaction by providing a distinct engagement surface that produces audible and tactile feedback when engaged, enabling reliable engagement confirmation without requiring complex integrated structures in either the container or lid.
2Reliability
If engagement mechanisms are added to provide feedback, then user confirmation of proper sealing is improved, but manufacturing complexity increases
Solution Approach 1:
The engagement mechanism is segmented into separate, independently manufacturable components: the annular ring for the container neck and the engagement mechanism for the lid. This allows each component to be manufactured using existing processes without requiring complex integrated tooling or assembly steps, maintaining ease of manufacture while providing reliable sealing confirmation through audible and tactile feedback.
Solution Approach 2:
The annular ring serves multiple functions: it provides structural reinforcement for the container neck, creates a distinct engagement surface for the lid, and generates audible and tactile feedback upon engagement. This multi-functionality reduces the need for additional specialized components, simplifying manufacturing while improving sealing confirmation reliability.
3Reliability
If the annular ring extends beyond the thread, then engagement security is improved, but device complexity increases
Solution Approach 1:
The annular ring is implemented as a separate, attachable component rather than an integrated part of the container neck molding. This segmentation allows the ring to extend beyond the thread for improved engagement security while keeping the container manufacturing process simple and modular, avoiding increased device complexity in the neck structure itself.
Solution Approach 2:
The annular ring is pre-formed and attached to the container neck before lid assembly. This preliminary action ensures proper positioning and alignment, allowing the ring to extend beyond the thread for enhanced engagement security without requiring complex real-time adjustments or integrated positioning mechanisms that would increase device complexity.

AI summary
The present invention relates to a container and a lid for food products, wherein the lid produces audible and tactile feedback when the container is closed with the lid. The invention further relates to a method for forming a lid for engagement with a container for food products. The container with a lid comprises a body with a neck surrounding an opening; at least one thread on the neck; at least one thread on the lid for engaging the at least one thread on the neck; and an engagement mechanism on the lid to secure the lid to the body when the lid is in a fully engaged position. Audible and tactile feedback are produced when the lid moves into the fully engaged position.
