Flexible Flap Medicine Container Adapter for Secure Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for dispensing liquid medicine are prone to contamination and unauthorized access due to the vulnerability of the source container during transfer, particularly when using a simple plunger.
Innovation Solution
A medicine container with a flexible flap that seals the opening, which can be opened by a hand-operated plunger to allow controlled dispensing, providing a tamper-evident and child-resistant seal that re-closes after use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple plunger is used to dispense liquid medicine, then the dispensing operation is simple and easy to operate, but the source container becomes vulnerable to contamination and unauthorized access
Solution Approach 1:
The patent introduces an adapter as an intermediary component between the container and the plunger. The adapter includes a flexible flap that acts as a mediator to control access to the container contents. The plunger operates the flap through the adapter without directly exposing the container opening, thus maintaining security while enabling simple operation.
Solution Approach 2:
The system is segmented into distinct functional components: the container, the adapter with flap mechanism, and the plunger. This segmentation allows the adapter to provide security functions (flap coverage) while the plunger provides dispensing function, resolving the contradiction between security and ease of operation.
2Productivity
If the container opening is left open for dispensing, then the dispensing process is fast and efficient, but bacteria and contaminants can fall into the container and spoil the medicine
Solution Approach 1:
The flexible flap transitions dynamically between closed and open states. During dispensing, the flap opens to allow rapid liquid flow. When dispensing stops, the flap automatically returns to closed position to prevent contamination. This dynamic behavior enables both fast dispensing and contamination prevention.
Solution Approach 2:
The dispensing action occurs rapidly through the open flap, minimizing the time the opening is exposed. The quick in-and-out motion of the plunger rushes through the dispensing process before the flap can close, reducing contamination risk while maintaining high productivity.
3Reliability
If a secure seal is implemented to prevent unauthorized access, then child resistance and tamper evidence are improved, but the operation may become more complex and difficult for individuals with impairments
Solution Approach 1:
The flexible flap is designed to be self-operating through the plunger mechanism. When the plunger is inserted and pressed, it automatically pushes the flap open without requiring additional actions from the user. The system serves itself by converting the simple plunger pressing motion into flap opening, maintaining ease of operation while providing secure access.
Solution Approach 2:
The flap material and geometry are designed to change its mechanical parameters (flexibility, opening force) to be easily actuated by the plunger. This parameter optimization ensures that even individuals with limited hand strength can operate the secure seal without complex mechanisms.
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 solution effectively prevents contamination and unauthorized access while allowing easy operation by individuals with impairments, ensuring a secure and efficient dispensing process.
Implementation Method 1
A flexible flap is disposed at the distal end of the inner sidewall such that the liquid medicine in the container cannot flow through the opening when the flexible flap is in a resting position
Implementation Method 2
The plunger is shaped to apply a force to the flexible flap, thereby operating the flexible flap

AI summary
Disclosed in this specification is a medicine container with a flexible flap covering the opening of the container. The opening is closed by the flexible flap when the flexible flap is in a resting position and the opening is opened when the flexible flap is in a flexed position. A hand-operated plunger is equipped with an end configured to mate with the opening such that a seal is established between the plunger and the opening. The plunger is shaped to apply a force to the flexible flap, thereby operating the flexible flap.
