Dispensing Valve Structure for Precise Dose and Air Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dispensing devices for solid, powder, or liquid contents are inconvenient for precise dosage, prone to contamination, and expose contents to air, leading to oxidation and pollution issues when trying to extract a fixed amount.
Innovation Solution
A dispensing device with a contents passing means that adjusts the passing space to securely guide a fixed amount of contents, includes a valve to prevent excess passage, and a receiving part to resist excess contents, allowing for stable and controlled dispensing without tilting or shaking the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cap opening method is used to extract contents, then contents can be accessed, but contents are exposed to air and contamination
Solution Approach 1:
The dispensing device segments the content extraction process by providing a dedicated dispensing channel that separates the opening/closing function from the content access function. The cap can be opened for dispensing while the main storage remains closed, allowing content to be dispensed without exposing the entire contents to air and contamination.
Solution Approach 2:
The dispensing device acts as an intermediary mechanism between the closed storage container and the user. It provides a controlled passage through the cap that allows content to be dispensed without requiring full opening of the container, thus mediating between content protection and content accessibility.
2Measurement precision
If pump type containing apparatus is used to dispense contents, then contents can be dispensed one at a time, but operating distance is large and operation is complex
Solution Approach 1:
Instead of moving the entire containing apparatus body up and down as in conventional pump type devices, this invention inverts the approach by keeping the container stationary and using a dispensing mechanism within the cap that moves to dispense contents. This reduces operating distance and simplifies the operation while maintaining precise dispensing capability.
Solution Approach 2:
The dispensing device incorporates a movable dispensing component that can dynamically adjust its position and operation. The dispensing channel and associated mechanisms can move within the cap structure to control content flow, providing precise dosage without requiring large-scale movement of the entire apparatus.
3Ease of operation
If conventional tilting method is used to withdraw contents, then contents can be accessed, but precise dosage control is difficult and overuse occurs
Solution Approach 1:
The dispensing device incorporates a self-regulating mechanism that automatically controls the dispensing process. The cap structure with integrated dispensing channel and closing mechanism allows the system to self-regulate content flow and dosage without requiring user judgment or manual measurement, preventing overuse while maintaining ease of operation.
Solution Approach 2:
The dispensing device provides feedback control through its mechanical structure. The interaction between the dispensing channel, content pressure, and closing mechanism creates a self-regulating system that responds to content flow conditions, ensuring precise dosage control and preventing overdispensing.
4Ease of operation
If cap is opened to access contents, then contents can be taken out, but entire contents are exposed and oxidation occurs
Solution Approach 1:
The device segments the opening function from the storage function. The cap can be opened to activate the dispensing mechanism while the main storage container remains closed, allowing content retrieval without exposing the entire contents to air and preventing oxidation.
Solution Approach 2:
The dispensing channel within the cap serves as an intermediary that allows selective content removal without full exposure. It mediates between the closed storage environment and the external environment, enabling content retrieval while maintaining protection against oxidation for the remaining contents.

AI summary
The present invention relates to a dispensing device, a valve, a containing apparatus having same, a contents moving apparatus, and a contents apparatus, comprising a passing operation unit provided in the housing, for moving and guiding contents, wherein the passing operation unit comprises a contents passing means for moving the contents. Unlike conventional art, the present invention may secure a space for passing contents while preventing reception of contents, which exceeds a demand, by adjusting a passing space and a receiving space, stably induce passing of a demanded amount of contents within a predetermined range, and prevent remaining of contents more than necessary by limiting the space for receiving the contents, thereby enabling adjustment of the amount (number) of contents being received.
