Two-Part Container Lid With Detachable Hatch Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grab-and-go fast food outlets lack a viable means for customers to safely dunk baked confections like biscotti into beverages without risking spills and injuries, due to disposable lids designed for secure but non-reversible attachment to containers, which conflicts with the on-the-go consumption philosophy.
Innovation Solution
A disposable two-part container lid with a reclosable hatch cover part connected to a brim mount via a detachable hinge, allowing the lid to pivot between fully closed and fully opened positions for unobstructed access to the beverage while remaining attached to the container, enabling dunking and sipping without removing the lid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable lids are designed for secure attachment to containers, then spill prevention is improved, but customer access to beverage for dunking confections is worsened
Solution Approach 1:
The lid is divided into two functional segments: a secure brim mount portion that attaches to the container and a separate hatch cover that can be opened independently. This segmentation allows the lid to maintain secure attachment while providing controlled access through the hatch opening, resolving the contradiction between spill prevention and customer access for dunking confections.
Solution Approach 2:
The hatch cover acts as an intermediary mechanism between the secure lid and the beverage contents. It provides a controlled access point that mediates between the need for secure closure and the need for customer access, allowing dunking operations without compromising overall lid security or causing spills.
2Reliability
If disposable lids are designed for secure attachment to containers, then spill prevention is improved, but lid removal for access becomes more difficult and risky
Solution Approach 1:
The access function is extracted from the main lid body and implemented through a separate hatch cover mechanism. This extraction eliminates the need to remove the entire securely attached lid for dunking operations, thereby removing the harmful factor of injury risk associated with lid removal while maintaining spill prevention through the secure brim mount.
3Device complexity
If a single-piece lid design is used, then device complexity is reduced, but adaptability for multiple functions (dunking, sipping, cooling) is worsened
Solution Approach 1:
The hatch cover is designed with dynamic characteristics, allowing it to be opened to various degrees (fully open for dunking, partially open for sipping or cooling). This dynamic capability enables multiple functions within a relatively simple structure, as the same hatch mechanism adapts to different customer needs without requiring complex additional components.

AI summary
A two part container lid for a container including a separately moulded brim mount part with a hatch opening in a top portion, reversibly clamped onto an rolled rim of the container and a separately moulded hatch cover part, sized and shaped to reversibly fit over the hatch opening. The hatch cover part is coupled to the top wall of the brim mount part by a detachable hinge thus pivoting the hatch cover part over the hatch opening between a fully closed position and a fully opened position and any intermediate position therein, thereby providing access to the beverage within the container without removing the two part container lid from the container. Detaching the hatch cover part from the brim mount part converts the two part container lid into a hybrid lid covering partially covering the container while permitting access to the contents within the container through the hatch opening.
