Slidable Spout Cap with Sealing Ribs for Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing containers for flowable products lack an efficient and sanitary spout fitment and cap assembly that allows for easy dispensing without additional components, such as straws, and ensures secure closure to prevent leakage and contamination.
Innovation Solution
A spout fitment and cap assembly featuring a tubular shape with horizontal sealing ribs for secure attachment to the container, a slidable cap with flow openings, and interlocking rings for position retention, fabricated from polypropylene, which can be actuated between closed, open, and partially open positions using an ultrasonic bonding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional spout closure system is used, then the container can be sealed, but it requires additional components (straws) for dispensing and lacks sanitary dispensing capability
Solution Approach 1:
The cap integrates both the closure function and the dispensing function into a single component. The cap includes a closure portion that seals the spout and a dispensing portion with flow openings, eliminating the need for separate straws or dispensing mechanisms while maintaining both sealing and dispensing capabilities
Solution Approach 2:
The cap serves multiple functions simultaneously: it acts as a closure to seal the spout, provides a dispensing mechanism through flow openings, and includes retention features to maintain positional stability. This multi-functional design replaces traditional multi-component systems with a single versatile component
2Productivity
If the cap is made fully open for dispensing, then product flow is enabled, but leakage and contamination risks increase
Solution Approach 1:
The cap is designed to be movable relative to the spout fitment, allowing it to transition between different positions. The retention features enable the cap to be held in specific positions (open, closed, or partially open) while maintaining secure attachment, providing dynamic control over the dispensing state to balance productivity and contamination prevention
3Reliability
If the cap is secured tightly to prevent decoupling, then reliability is improved, but ease of operation for opening/closing deteriorates
Solution Approach 1:
The retention features are designed to automatically engage when the cap is in the closed or open positions, providing secure retention without requiring additional fastening actions. The features are pre-configured to interact with corresponding elements on the spout fitment, ensuring reliable attachment while maintaining easy operation for position transitions

AI summary
A spout fitment and cap assembly for a dispensing container is provided. The spout fitment and cap assembly includes a fitment and a cap. The fitment includes a generally tubular shape surrounding a central axial passage and multiple horizontal sealing ribs configured to secure the fitment to the dispensing container. The cap includes a generally tubular shape with an annular wall extending circumferentially about an exterior surface of the tubular shape, a central plug portion, and multiple flow openings surrounding the central plug portion. The cap is slidably coupled to the fitment and is configured to be actuated between a first position and a second position through an application of force to the annular wall.
