Hinged Secondary Dispensing for Complete Rigid Container Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rigid containers with primary dispensing systems often leave residual flowable substances due to ineffective dispensing mechanisms, particularly for viscous materials, and existing secondary systems are complex, costly, or require significant design modifications.
Innovation Solution
A secondary dispensing system with a flanged aperture, hinged surface panel, and headed pin that integrates with the container without altering its design, allowing complete gravity-based evacuation of residual substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a primary dispensing system (cap or valve) is used in a rigid container, then the container can store and dispense flowable substances, but residual substance remains inside the container and cannot be completely evacuated
Solution Approach 1:
The invention divides the dispensing function into two separate systems: a primary dispensing system (cap or valve) for controlled dispensing, and a secondary dispensing system (removable base with aperture) for complete evacuation of residual substance. This segmentation allows each system to optimize for its specific function, with the secondary system providing access to the container base where residual material accumulates.
Solution Approach 2:
The invention extracts the base segment of the container as a separate removable component. By making the base detachable, users can remove it entirely to access and completely empty residual substance from the container interior, which would otherwise be inaccessible through the primary dispensing system alone.
2Quantity of substance
If secondary dispensing systems with collapsible inserts or inflatable bladders are used, then dispensing capability is enhanced, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention uses a simple removable base segment that can be easily manufactured and replaced if needed. Rather than incorporating complex collapsible or inflatable mechanisms, the solution employs a straightforward detachable component that achieves the same functional goal with minimal complexity and lower manufacturing costs.
Solution Approach 2:
Instead of adding complex mechanisms inside the container, the invention extracts the base as a separate removable component. This simplifies the overall system by eliminating the need for collapsible inserts or inflatable bladders, achieving complete dispensing through a simple mechanical separation of the base from the main container body.
3Quantity of substance
If secondary dispensing systems require complete redesign of the container base to make it detachable, then complete evacuation is enabled, but manufacturing complexity and cost increase
Solution Approach 1:
The container is segmented into a main body and a removable base segment. This segmentation allows the base to be detached for complete evacuation while maintaining simplicity in manufacturing, as the separation interface can be designed as a straightforward mechanical connection rather than requiring complete redesign of the entire container structure.
4Quantity of substance
If the container internal surfaces are tapered to facilitate complete evacuation, then residual substance can be dispensed, but manufacturing precision requirements increase
Solution Approach 1:
Rather than modifying the internal surfaces of the container to be tapered, the invention extracts the base as a removable component. This approach achieves complete evacuation without imposing additional manufacturing precision requirements on the container's internal surface geometry, as the removal of the base itself provides access to residual material.
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
Ensures complete emptying of the container contents with minimal effort, reducing waste and manufacturing costs, while maintaining container integrity and usability across various industries.
Implementation Method 1
In the closed position, the headed pin is inserted into the flanged aperture, effectively sealing it and preventing leakage
Implementation Method 2
The surface panel is secured via a hinge, enabling articulated rotational movement between an open and closed position
Implementation Method 3
In the open position, the headed pin is removed, enabling gravity-based dispensing of the totality of the residual substance

AI summary
A secondary dispensing system for a rigid container of a flowable substance for improved dispensing capability is disclosed, which comprises a flanged aperture positioned along the outer perimeter of the base of the container, a surface panel configured to rest on the external surfaces of the container, a hinge that enables articulated rotational movement of the surface panel, and a headed pin affixed to the surface panel and configured to insert into and seal the flanged aperture. In the closed position of the system, the headed pin seals the flanged aperture. In its open position, the headed pin is disengaged to allow gravity-based dispensing of the totality of the residual flowable substance without requiring tapering of the container's internal surfaces. The system integrates with the container without materially modifying its design. The flowable substance may be a liquid, gel, mixture, or granular material.
