Drinking Container Lid Self-Locking Spout Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking cup lids with flexible plastic tubes require an additional cap to maintain a tight seal, which complicates one-handed operation and can be a hindrance when drinking through the spout.
Innovation Solution
A drinking cup lid design where the kinked drinking spout is secured within a guide carriage on the base element, eliminating the need for an additional cap, with a guide carriage that articulates and displaces to lock the spout in place, providing a defined buckling point and ensuring a reliable seal through a meandering S-shaped configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional cap is used to secure the kinked drinking spout, then a tight seal is achieved, but the device complexity increases and one-handed operation becomes difficult
Solution Approach 1:
The patent combines the cap function and spout securing function into a single integrated component. The spout itself is designed to function as the securing mechanism through its S-shaped configuration that creates friction engagement with the base element, eliminating the need for a separate cap component while maintaining sealing reliability
Solution Approach 2:
The patent extracts the cap component from the system entirely, replacing it with the spout's own geometric configuration. The S-shaped spout design allows it to self-secure within the base element through friction engagement, removing the additional cap that complicated one-handed operation while preserving the tight seal function
2Reliability
If an additional cap is used to hold the kinked spout in position, then sealing is improved, but ease of operation deteriorates due to the need for two-handed operation
Solution Approach 1:
The spout design is self-sufficient, using its own S-shaped geometry to create the securing mechanism. The friction engagement between the spout and base element automatically maintains the kinked position and seal without requiring a separate cap or complex manual operation, enabling easy one-handed use
Solution Approach 2:
The flexible spout material allows the spout to be deformed into the S-shape and maintain that configuration through elastic memory and friction engagement with the base element. This flexibility enables the spout to self-secure without additional components, improving ease of one-handed operation while maintaining seal tightness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simple, one-handed operation with a self-locking mechanism that maintains a tight seal without the need for an additional cap, enhancing usability and security against unintentional opening or spillage.
Implementation Method 1
the drinking spout can return to its original shape due to the elastic restoring forces
Implementation Method 2
The guide carriage (30) is guided in a sliding link (13) in the base element (10)

AI summary
The invention relates to a drinking container lid (100) for a drinking bottle, consisting of a base element (10) having at least one pour opening (19) in a base plate (11), which is surrounded by a raised edge (15) and has a flexible drinking nozzle (23) with an internal flow channel (24), which can be blocked by bending the flexible drinking nozzle (23). The drinking nozzle (23) is retained in a guide carriage (30) pivotally mounted on the base element (10). The bent drinking nozzle (23) can be mounted within a receiving space (14) surrounded by the edge (15). A detachable blocking means is provided in the drinking container lid (100), which retains the guide carriage (30) in a blocking position against the restoring force of the bent drinking nozzle (23).
