Adjustable Locking Mouthpiece for Leak-Proof drinking Bottles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional water bottles face significant challenges with leakage and spilling due to ineffective seals in conventional closures, leading to messy situations and potential damage to personal belongings.
Innovation Solution
An adjustable locking mouthpiece with a locking mechanism that creates a tight seal, even when the bottle is turned upside down or subjected to physical impacts, using a circumferential ridge and groove system for a secure fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional screw-on caps or snap-on lids are used, then the bottle is easy to open and close, but the seal becomes ineffective over time leading to leakage
Solution Approach 1:
The closure system transitions from a static seal to a dynamic locking mechanism. The spout can rotate between open and closed positions, and the locking mechanism dynamically engages or disengages based on user action. This dynamic design maintains seal effectiveness while preserving ease of operation.
Solution Approach 2:
The closure is divided into separate functional components: the spout assembly, the locking mechanism, and the sealing elements. This segmentation allows each component to perform its specific function optimally - the spout for drinking, the lock for securing, and the seal for preventing leakage.
2Device complexity
If simple screw-on caps are used, then the device complexity is low, but leakage prevention is insufficient
Solution Approach 1:
The locking mechanism is nested within the cap structure, with the spout assembly nested within the cap. The circumferential groove and ridge system is integrated into the cap's interior. This nesting approach adds leakage prevention functionality without significantly increasing external complexity.
Solution Approach 2:
Multiple functions are merged into a single closure assembly: sealing, locking, and spout positioning. The circumferential groove serves both as a structural feature and as part of the locking mechanism, combining multiple functions into unified components.
3Ease of operation
If the bottle is designed for easy drinking with spouts, then the ease of operation is improved, but the sealing capability deteriorates when the bottle is dropped or overfilled
Solution Approach 1:
The locking mechanism is engaged before any impact or overflow can occur, creating a pre-established seal that resists subsequent forces. The circumferential ridge and groove create a mechanical lock that prevents the spout from moving or leaking even when subjected to sudden impacts or overfilling conditions.
Solution Approach 2:
The circumferential groove and ridge create a curved, interlocking interface between the spout assembly and cap. This curved geometry distributes impact forces more evenly and creates a more robust mechanical lock compared to flat sealing surfaces, improving resistance to impact while maintaining drinking convenience.

AI summary
The invention discloses an adjustable locking mouthpiece for leak-proof drinking bottles designed for enhanced convenience and leak prevention. The disclosure further discloses a drinking container features a body extending from a neck to a base at the bottom, and is equipped with a cap that includes a lid assembly housing and a removable lid assembly. The lid assembly housing contains a cylindrical hole with a circumferential groove near an edge. The lid assembly features a straw with a proximal end for drinking and a distal end submerged in the container. The lid assembly includes a base member with circumferential ridge that fits securely into the circumferential groove of the lid housing by way of male-female type joint creating a leak-proof seal, ensuring that no liquid escapes even when the container is inverted.
