Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers for viscous substances face challenges in complete emptying, particularly for high viscosity fluids, and exposure to ambient air during discharge affects shelf life.
Innovation Solution
A container design utilizing an airtight structure with an outer and inner body, where manual pressure on the outer body forces air between the bodies to expel fluid through an orifice, ensuring complete discharge and preserving the fluid in vacuum to prolong shelf life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional container design is used for viscous substances, then the container structure is simple, but complete emptying cannot be achieved and residues remain
Solution Approach 1:
The container is divided into two distinct bodies: an outer body and an inner body. The inner body contains the fluid while the outer body provides structural support. This segmentation allows the inner body to be collapsed completely by external pressure, enabling complete emptying of viscous fluids without complex internal mechanisms.
Solution Approach 2:
The invention uses air pressure as a counteracting force against the weight and viscosity of the fluid. By applying manual pressure to the outer body, air is compressed and forces the inner body to collapse, pushing the fluid out through the orifice. This counterpressure mechanism enables complete discharge regardless of fluid viscosity or gravitational direction.
2Reliability
If conventional container emptying is used, then the discharge process is simple, but ambient air enters the container and affects shelf life
Solution Approach 1:
The container maintains a vacuum or inert atmosphere inside the inner body during storage and discharge. The airtight seal between the outer and inner bodies prevents ambient air from entering, preserving the fluid in a protected environment. This extends shelf life by preventing oxidation and contamination while maintaining a simple manual discharge operation.
3Ease of manufacture
If thin fabric is used for inner body to minimize resource consumption, then manufacturing cost is reduced, but structural strength may be compromised
Solution Approach 1:
The invention uses pneumatic pressure from compressed air to provide the force needed to collapse the inner body and discharge the fluid. This external pressure compensates for the limited structural strength of the thin fabric inner body, allowing it to be made from minimal material while still achieving complete emptying of viscous fluids.
Solution Approach 2:
The mechanical properties of the inner body are optimized by changing parameters such as material composition, thickness, and structural design of the thin fabric. These parameter adjustments allow the inner body to maintain sufficient strength for its function while minimizing material usage and resource consumption.
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 container achieves complete emptying against gravity and maintains fluid integrity by using captive air for pressure transfer, enhancing thermal insulation and reducing resource consumption.
Implementation Method 1
manual pressure on the airtight container. Air retained in the space between the two packaging bodies transfers the force to the fluid inside the inner body. The overpressure induced by this pumping action unloads the fluid from an orifice of the inner body
Implementation Method 2
Air retained in the space between the two packaging bodies transfers the force
Implementation Method 3
Owing to the captive air enclosed between its outer and inner bodies, the proposed container exhibits improved thermal insulation, akin to the operating principle of a vacuum flask

AI summary
Problem A container for viscous substances, especially liquids, is typically operated such that discharge is effected by, for example, folding or pumping action exerted by a means provided atop the container. Complete emptying of a conventional container in most cases cannot be achieved. Some residues may be removed by the action of gravity. However, for substances of higher viscosity, retrieving residues from the container remains a challenge. Furthermore, the shelf life of the fluid may be adversely affected by ambient air entering the container as it is being emptied. The invention aims to facilitate an almost complete discharge of a container, regardless of gravity. Moreover, the viscous fluid is to be preserved in vacuum to prolong its shelf life. Solution Container for a preferably viscous fluid having a compressible, preferably elastic, outer body (1) and an inner body (2) opening out of the container and comprising the fluid, characterized in that captive air is enclosed between the outer body (1) and inner body (2) and the inner body (2) is affixed within the outer body (1) such that when compressive force is applied upon the outer body (1), the captive air transfers the force unto the inner body (2), displacing and discharging the fluid from the container.
