Frangible Dispensing Package with Adapter for Controlled Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing single-dose flexible dispensing packages lack controlled dispensing mechanisms and are not designed to direct content to fluid transport devices, often resulting in uncontrolled dispensing and requiring two-hand operation.
Innovation Solution
A dispensing package with a rigid backing, a fold line, and a frangible section that incorporates a fluid transport device and adapter to direct the product flow through the adapter to the transport device, allowing controlled dispensing and resealing of the outlet port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a frangible section is used to enable easy opening, then ease of operation is improved, but controlled dispensing capability deteriorates
Solution Approach 1:
The package wall is segmented into a frangible section that breaks upon folding and a separate adapter component that provides controlled dispensing. The frangible section is divided into first and second portions that separate to create an opening, while the adapter with its valve mechanism handles the controlled release of contents.
Solution Approach 2:
An adapter serves as an intermediary component between the frangible opening and the dispensing mechanism. The adapter includes a valve that controls the flow of contents from the package, mediating between the simple break-open action and the desired controlled dispensing outcome.
2Ease of operation
If the package is designed for direct application to surfaces, then ease of operation is improved, but adaptability to fluid transport devices deteriorates
Solution Approach 1:
The adapter is designed with universal compatibility features that allow it to work with various fluid transport devices including syringes, droppers, and sprayers. The adapter's standardized interface and valve mechanism enable it to serve multiple dispensing functions while maintaining ease of operation for direct application.
3Ease of operation
If the frangible wall section ruptures completely, then ease of opening is improved, but manufacturing precision deteriorates
Solution Approach 1:
The frangible wall section has differentiated local qualities with a first portion designed to break and a second portion designed to remain intact. This local differentiation ensures reliable opening while maintaining structural integrity where needed, achieving both ease of operation and manufacturing precision.
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
Enables controlled dispensing of products through fluid transport devices, such as needles or sprayers, and allows for resealing, improving usability and reducing the need for two-hand operation.
Implementation Method 1
a frangible section in form of a score or a groove such that when said backing is bent or folded this frangible section will break

AI summary
A dispensing device includes a backing, at least a first product compartment and a fluid transport device. The backing is a frangible section adapted to at least partially open as the backing is moved from a first position toward a second position. The product compartment and the fluid transport device are each disposed on the backing in confronting relationship to the frangible section. According to a method, a dispensing device is provided in which the backing is moved from the first position toward the second position to compress the first product compartment and cause the content to be dispensed through the fluid transport device.
