Viscous Material Container with Movable Disc Seal for Complete Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for viscous materials, such as adhesives or sealants, suffer from inefficiencies in utilizing interior space and leave residual amounts of material due to the folding of the film against the container bottom during removal, limiting the movement of the follower plate and preventing complete evacuation.
Innovation Solution
A container design featuring a disc-shaped element that is detachably sealed to the side wall, allowing for the element to move closer to the container bottom without folding, facilitated by a releasable sealing mechanism, enabling full utilization of the container interior and simplified filling and removal processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a film bag is used to line the container interior and hold viscous material, then the material can be contained and removed using a follower plate, but the film folds against the container bottom during removal, forming an undesirable limitation that prevents complete evacuation and leaves residual material
Solution Approach 1:
The invention extracts the sealing function from the continuous film bag and concentrates it into a discrete disc-shaped element. This disc element can be detached from the container wall and moved freely to the container bottom, eliminating the folding limitation that prevented complete material evacuation. The sealing function is maintained through a sealing ring on the disc that engages with the container wall, while the disc itself can be positioned optimally for complete removal.
Solution Approach 2:
The disc-shaped element transitions from a static sealed position against the container wall to a dynamic removable position at the container bottom. This dynamic repositioning allows the sealing element to adapt during the removal process, first sealing the material in place, then moving to allow complete evacuation without film folding limitations.
2Reliability
If the follower plate is pressed against the folded film at the container bottom, then the film can be sealed to contain material, but the folded film limits the removal movement and prevents the follower plate from evacuating the entire amount of material
Solution Approach 1:
The sealing function is extracted from the bulk film material and concentrated into a dedicated sealing ring on the disc-shaped element. This separates the sealing function from the limitation of film folding, allowing the seal to be reliable while the disc itself can be moved freely to enable complete evacuation without being constrained by folded film.
Solution Approach 2:
The continuous film bag is segmented into a disc-shaped element that can be independently positioned and moved. This segmentation allows the sealing portion (disc with sealing ring) to be detached and repositioned at the container bottom, separating the sealing function from the evacuation limitation and enabling complete material removal.
3Volume of moving object
If the container interior is filled to maximum volume, then space utilization is improved, but the folded film at the bottom creates dead space where residual material cannot be removed
Solution Approach 1:
The sealing function is extracted and concentrated into a movable disc element that can be positioned at the container bottom. This removes the folding limitation that created dead space, allowing the container to be filled to maximum volume while enabling complete evacuation of all material including what would have been trapped in the folded film area.
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 design significantly reduces residual material and allows for nearly complete evacuation of the container, enhancing space utilization and simplifying the filling and removal processes, including automated filling capabilities.
Implementation Method 1
a compressive force applied in the direction of the container bottom, preferably downwards, which acts on the disc-shaped element, wherein the compressive force exceeds a holding force, in particular adhesive force, of the first sealant for holding the disc-shaped element
