Unitary Dispenser Cap With Rotating Measuring Ducts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring and dispensing bulk substances from storage containers are cumbersome, imprecise, and prone to contamination, requiring multiple items and increasing the risk of spills and user error, especially in healthcare settings where accuracy and consistency are critical.
Innovation Solution
A single unitary dispenser and measuring cap device that attaches to storage containers, featuring one or more measuring chamber ducts with predetermined volumes, allowing for precise measurement and dispensing without exposing the substance to contaminants, by rotating the duct between filling and dispensing positions, thus preventing direct contact with the external environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional separate measuring devices are used, then measurement capability is provided, but device complexity and time consumption increase
Solution Approach 1:
The patent combines the storage container closure, measuring device, and dispensing mechanism into a single integrated unitary closure. The closure includes a closure body with a closure opening, a closure cap, and a closure body cap that work together as one system, eliminating the need for separate measuring devices and reducing the number of components required for measurement and dispensing operations.
Solution Approach 2:
The unitary closure serves multiple functions simultaneously: it seals the storage container, provides a measuring mechanism for precise dosing, and acts as a dispensing device. The closure cap and closure body cap can be configured to provide both sealing and measuring capabilities, allowing one component to perform what previously required multiple separate items.
2Measurement precision
If multiple separate items are used for measuring and dispensing, then measurement function is achieved, but ease of operation deteriorates
Solution Approach 1:
By integrating the measuring and dispensing functions into a single unitary closure system, the patent eliminates the need for users to handle multiple separate items. The closure cap and closure body cap work together as one coordinated system, simplifying the operation to a single integrated action that achieves both measurement and dispensing.
3Measurement precision
If traditional open-top measuring devices are used, then measurement is possible, but contamination risk increases
Solution Approach 1:
The patent integrates the sealing function directly with the measuring and dispensing mechanism in the unitary closure. The closure cap and closure body cap form a sealed system that encloses the substance during measurement and dispensing operations, preventing exposure to contaminants while maintaining measurement capability through the integrated measuring chambers or markings on the closure components.

AI summary
Spill and contaminant resistant dispensers and measuring cap devices and methods for measuring and dispensing a desired amount of a bulk particulate, powdery, granular or viscous liquid substance from a storage container through a cap or a dispenser are provided. A dispenser and measuring cap is attached to a storage container or comprises an integral storage container. The dispenser and measuring cap has one or more measuring chamber ducts, each having a different predetermined volume. The measuring chamber ducts are selectively and separately operationally aligned with an internal funnel stem and a dispensing spout. A selected measuring chamber duct is filled with the substance by inverting the cap and attached container. A measured amount of the substance is captured and dispensed, and the unused portion of the substance retained in the storage container without exposure to outside contaminants or implements, by rotating the duct into operational alignment with the spout.
