Liquid Dose Container With Stabilization Chamber Spill Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for dispensing liquids, particularly for individuals with dysphagia or for precise medication dosing, often result in accidental over-delivery or spillage due to inclination or shaking, and fail to provide accurate volume dosing, especially when hot or cold beverages are involved.
Innovation Solution
A spill-resistant container design featuring a nonconcentric liquid withdrawal and deposit chamber system with a stabilization chamber and a single aperture for both air and liquid flow, allowing precise control of liquid dosage through a dosing chamber with a threaded plug for regulating volume, ensuring liquid delivery only when the container is upright.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional dosing device is used, then liquid can be dispensed, but accurate volume dosing cannot be achieved and spillage occurs during inclination or shaking
Solution Approach 1:
The container is divided into distinct functional zones: a deposit chamber for receiving liquid, a withdrawal chamber for dispensing, and a stabilization chamber with baffle structures. This segmentation allows each zone to perform its specific function independently, enabling accurate dosing while preventing spillage during movement.
Solution Approach 2:
The withdrawal chamber is nested within the deposit chamber, and the stabilization chamber is integrated into the structure. This nested configuration allows the baffle structures to effectively block liquid flow paths during inclination while maintaining compact dimensions for precise dosing.
2Reliability
If the container is designed to deliver liquid in upright position only, then spillage during inclination is prevented, but liquid delivery fails when container is inclined
Solution Approach 1:
The baffle structures are strategically positioned at specific locations within the stabilization chamber to create directional flow control. This local differentiation allows liquid to be blocked during unwanted inclination while permitting flow during intentional dispensing operations.
Solution Approach 2:
The baffle structures act as intermediary elements that mediate between the deposit chamber and withdrawal chamber. They selectively allow or block liquid passage based on the container's orientation, enabling conditional liquid delivery.
3Ease of manufacture
If a simple container structure is used, then manufacturing is easy, but accidental over-delivery of liquid occurs during shaking or inclination
Solution Approach 1:
The baffle structures are designed as simple geometric forms that can be integrated into standard manufacturing processes. Their straightforward geometry maintains ease of manufacture while providing effective flow control to prevent over-delivery.
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
The container effectively prevents accidental liquid delivery when inclined or shaken, providing repeatable and precise dosing of predetermined volumes, enhancing safety and convenience for dysphagia patients and medication administration.
Implementation Method 1
An air flow aperture in the withdrawal chamber allows air to flow into the deposit chamber
Implementation Method 2
A liquid flow aperture in the withdrawal chamber allows liquid to flow into the withdrawal chamber from the deposit chamber
Implementation Method 3
The baffle structures effectively block the liquid from entering into the withdrawal chamber when the container is inclined or shaken

AI summary
The present invention relates to a container for dispensing a predetermined volume of liquid wherein the container comprises: a liquid deposit chamber having an open first end and an opposing closed second end, a nonconcentric liquid withdrawal chamber having a open first end and an opposing closed second end, one or more apertures between said deposit and withdrawal chambers adapted to selectively permit liquid communication in controlled doses from the liquid deposit chamber to the liquid withdrawal chamber, a liquid stabilization chamber surrounding the liquid withdrawal chamber, and a base cap having a nonconcentric cavity in axial alignment with the liquid stabilization chamber and in liquid communication with the liquid deposit and withdrawal chambers.
