Plastic Ampoule Container With Integrated Valve for Precise Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers with detachable closure parts face issues with fluid leakage and inability to precisely dose or mix contents, especially when precise dosing or mixing is required, and they are not microbiologically safe during handling and removal.
Innovation Solution
A container with an integrated valve device that blocks and releases fluid flow, ensuring microbiological safety and precise dosing, allowing mixing and removal without external piercing, and featuring a modular design for various connection points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wall parts of the closure part are pressed into the hollow chamber to reduce the chamber cross-section, then the container prevents fluid leakage into the head part, but the container loses the ability to precisely dose or mix the dispensing medium
Solution Approach 1:
The container is divided into functionally distinct segments: the receiving body for fluid storage and the closure part with head space for dosing and mixing. This segmentation allows the receiving body to provide leakage prevention through its press-fit connection while the head space provides precise dosing and mixing capabilities, resolving the contradiction between reliability and measurement precision.
2Reliability
If the hollow chamber cross-section is reduced to prevent fluid penetration, then the container maintains hermetic sealing, but the container cannot allow controlled fluid transfer for dosing applications
Solution Approach 1:
The closure part is pre-formed with a reduced cross-section configuration that maintains hermetic sealing during storage and transport. When dosing is required, the closure part can be temporarily opened or accessed through the head space, allowing controlled fluid transfer while maintaining the hermetic sealing structure for the majority of the container's lifecycle.
3Reliability
If the closure part is detachably connected to prevent fluid escape, then the container achieves microbiological safety, but the container complexity increases with multiple connection and separation mechanisms
Solution Approach 1:
The closure part integrates multiple functions into a single component: the detachable connection provides both the hermetic seal for microbiological safety and the controlled access for dosing. The wall parts pressed into the hollow chamber simultaneously provide structural integrity, sealing, and dosing control, eliminating the need for separate complex connection mechanisms and reducing overall device complexity.

AI summary
Disclosed is a container, such as a filled and closed ampoule, comprising at least one plastic material, having a container part for receiving container contents and having ahead part which can be separated from the container part along a separation point and which is integrally connected to the container part before separation, wherein the container has a valve device which, in its closed position, blocks a fluid-conducting connection into the container part and, in its open position, releases this connection.
