Refillable Bottle Locking Check Valve for Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refillable bottles face sealing issues during filling due to difficulties in correctly positioning the check valve for actuation, leading to inefficient product transfer and potential leakage.
Innovation Solution
A refillable bottle design with a filling valve that locks the check valve in a closed position, allowing for easy manipulation to release it into an open position, ensuring a reliable seal during filling, and a product source with a socket for secure connection, facilitating refilling without the need for additional force or complex positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the check valve is elastically held in the closed position and opened by jet bearing contact, then the valve can be actuated to open the passage, but sealing problems occur because it is difficult to position the jet correctly with sufficient force
Solution Approach 1:
The check valve is pre-positioned in a locked closed state before use. The locking device maintains the valve in this position until a specific triggering action occurs, ensuring proper positioning is achieved in advance rather than relying on difficult real-time positioning during actuation
Solution Approach 2:
A locking device acts as an intermediary mechanism between the valve seat and the check valve. This locking device engages with the valve to maintain it in the closed position, providing a reliable sealing interface without requiring direct jet-bearing contact to both position and actuate the valve simultaneously
2Quantity of substance
If the pump is actuated multiple times to inject sufficient product volume, then the reservoir can be filled, but the positioning difficulty and sealing problems worsen with repeated actuations
Solution Approach 1:
The locking device pre-positions the check valve in the closed state before filling begins. This ensures that when the pump is actuated multiple times, the valve maintains consistent sealing contact with the seat, eliminating positioning variability that would worsen with repeated actuations
Solution Approach 2:
The locking device automatically maintains the valve in the correct position throughout the filling process. The system self-regulates to keep the valve sealed against the seat during multiple pump actuations, without requiring external intervention to reposition or re-seal the valve between strokes

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a reliable and intuitive refilling process that prevents leakage and ensures efficient product transfer, making the refillable bottle easier to use and more environmentally friendly by eliminating the need for frequent replacements.
Implementation Method 1
a communication passage between the source and the reservoir, the passage having a seating fitted with a check valve free to move relative to the seating between a sealed closed position and a position in which the passage is open

AI summary
A refillable bottle for dispensing a fluid product including a body in which a reservoir designed for conditioning the product is formed, the bottle including a dispensing device of the conditioned product that is mounted sealed on the body, the bottle being fitted with a reservoir filling valve arranged to enable communication of a product source with the reservoir to refill it, the valve including a communication passage between the source and the reservoir, the passage having a seating fitted with a check valve that is free to move relative to the seating between a sealed closed position and an open position of the passage, the bottle including a device for locking the check valve in the closed position, the device being arranged to be deactivated leaving the check valve in the closed position to release subsequent displacement of the check valve into the open position.
