Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging containers for viscous liquids, such as sealing agents or adhesives, face issues like disposal problems due to unchanged volume after use, inadequate sealing leading to content deterioration, and difficulties in single-handed operation and storage efficiency.
Innovation Solution
A packaging bag with a bonded sheet material made of synthetic resin, featuring a through hole at the front end for easy discharge, a nozzle inserting piece for secure nozzle attachment, and a squeezing mechanism with support parts and driving mechanism for efficient liquid extraction, allowing for single-handed operation and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filling container with a cylindrical body and bottom plate is used, then the viscous liquid can be contained and discharged, but the container volume remains unchanged after use causing disposal problems
Solution Approach 1:
The patent uses a flexible pouch bag made of laminated film instead of a rigid cylindrical container. The pouch bag can be completely emptied of viscous liquid, reducing waste volume to minimal residual amounts, while the flexible structure maintains sealing integrity throughout the discharge process.
2Ease of operation
If the bottom plate is disposed in the cylindrical body to slide toward the distal end, then the viscous liquid can be discharged, but the bottom plate cannot sufficiently seal the tube body causing content deterioration
Solution Approach 1:
The pouch bag design with integrated nozzle and self-sealing structure allows the container to maintain its own sealing without requiring an external bottom plate mechanism. The flexible material itself provides the sealing function, eliminating the need for separate sealing components that require manual operation.
3Loss of substance
If a film package type container is used with a special caulk gun, then waste after use is significantly reduced, but the device complexity increases
Solution Approach 1:
The pouch bag is designed to be compatible with standard existing dispensing equipment, eliminating the need for specialized caulk guns. The universal design allows the same pouch bag to be used with various dispensing mechanisms, reducing device complexity while maintaining waste reduction benefits.
4Productivity
If two bar bodies are aligned in parallel for squeezing, then the viscous liquid can be extracted, but an operator cannot operate the apparatus with a single hand
Solution Approach 1:
The patent integrates the squeezing mechanism directly into the pouch bag structure itself, combining the container and dispensing mechanism into a single unit. This eliminates the need for separate external squeezing bars, allowing the user to operate the device with one hand while maintaining effective liquid extraction.
5Reliability
If the packaging bag is made of bonded sheet material with gas barrier layer, then product quality is maintained over time, but manufacturing complexity increases
Solution Approach 1:
The pouch bag uses laminated film structure with multiple layers including gas barrier layers to protect the viscous liquid from degradation. This composite material structure maintains product quality over time while the lamination process is a standard manufacturing technique that does not significantly increase manufacturing complexity.

AI summary
A squeezing device capable of squeezing a viscous liquid in a packaging bag includes a pair of bag body support parts for stretching and supporting the bag bodies by fixing the front end and the rear end of a bag body and performing fixing of the rear end by applying a tension thereto rearwards; a squeezing mechanism part which is so provided as to be capable of sliding in the direction towards the front end in such a state the rear end of the bag supported by the bag body support parts is held from the upper and lower sides; and a drive mechanism part for slidingly driving the squeezing mechanism part in the direction towards the front end. The squeezing mechanism part is installed at the tip end of the device, and the drive mechanism part includes a slide bar disposed parallel to the sliding direction of the squeezing mechanism part.
