Drink-Through Spout Cap With Threaded Engagement And Membrane Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drink-through spout caps for beverage bottles require the container to be filled before use, making it difficult to transport and prone to contamination, and often leak when adapted for multiple containers.
Innovation Solution
A drink-through spout cap with a top wall, sidewall, and spout that can be directly attached to a beverage bottle, featuring a threaded region for secure engagement and a cap membrane seal to prevent leakage, along with a cover for protection, allowing for easy assembly and use without pre-filling the bottle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the container is filled with beverage before attaching the spout cap, then the spout cap can be properly sealed and used, but the manipulation becomes difficult and risky during transport and contamination may occur
Solution Approach 1:
The spout cap is designed to be attached to the bottle before filling with beverage. The preliminary attachment allows the sealing surfaces to be properly positioned and the threading to be engaged without the weight and spill risk of a full container, making the attachment operation easier and safer while ensuring reliable sealing is achieved before use
2Adaptability or versatility
If the spout cap is designed to fit multiple container types, then versatility is improved, but leakage occurs
Solution Approach 1:
The spout cap incorporates a lip with a specific height range (0.1-5 mm) that creates a localized sealing zone at the bottle opening. This localized sealing structure ensures reliable sealing at the critical interface between the cap and bottle, while the overall cap design can accommodate different bottle types through the threaded engagement mechanism
3Reliability
If the lip height is increased to improve sealing, then leakage prevention is enhanced, but the spout cap becomes more complex and harder to manufacture
Solution Approach 1:
The lip height is optimized within a specific range (0.1-5 mm) that provides effective sealing without excessive complexity. This parameter optimization ensures reliable leakage prevention while maintaining manufacturability, avoiding both too-small lips that fail to seal and too-large lips that complicate the molding process

AI summary
A drink-through spout cap for a beverage bottle having a body and a neck, a set of a cover and such a drink-through spout cap, a drinking device comprising a beverage bottle and a set, and methods of manufacturing or preparing a drinking device. The drink-through spout cap (10) has a top wall (32) and a sidewall (34) extending therefrom, the top wall (32) being provided with a spout (36) having an aperture (38) formed therein. The sidewall (34) has an inner surface (34A) and an outer surface (34B), the inner surface (34A) being provided with a threaded region (40) adapted to engage the threaded region (42) of the bottle (12). A lip (44) extends from the top wall (32) and has a lip height which is smaller than half of the sidewall length.
