Packaging Combination With Plait-Like Portion For Viscous Material Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging combinations for viscous or granular materials are expensive due to the use of large, rigid dispensing tubes made from costly plastics, and they often result in accidental discharge of filling material when the bag-shaped casing is opened outside the tube for reuse, leading to environmental pollution.
Innovation Solution
A packaging combination featuring a tubular casing with a plait-like portion at one end and a dispensing device that allows easy opening and dispensing by extending the closure means beyond the dispensing opening, preventing accidental discharge, and includes a closure cap for secure storage and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large rigid tube is used to accommodate the bag-shaped casing, then the casing can be safely stored and transported, but the cost increases due to expensive plastics and the device becomes more complex
Solution Approach 1:
The invention extracts the dispensing function from a large rigid tube and relocates it to a small cap that attaches to the dispensing device. The cap contains a dispensing nozzle and can be screwed onto the dispensing device, eliminating the need for a large rigid tube while maintaining safe storage and transport capabilities.
Solution Approach 2:
The dispensing system is segmented into separate functional components: the tubular casing, the dispensing device, and the removable cap with dispensing nozzle. This segmentation allows each component to be optimized independently and reduces the overall complexity by eliminating the need for a large rigid tube to accommodate the entire casing.
2Ease of repair
If the bag-shaped casing is opened outside the rigid tube for reuse, then the rigid tube can be reused multiple times, but filling material is accidentally discharged and pollutes the environment
Solution Approach 1:
The plait-like portion is pre-formed at the end of the tubular casing during manufacturing, creating a built-in opening mechanism that eliminates the need to open the casing outside the dispensing device. The closure means can be easily removed from the plait-like portion, allowing the casing to be opened safely within the controlled environment of the dispensing device.
Solution Approach 2:
The plait-like portion acts as an intermediary structure between the sealed tubular casing and the dispensing opening. It provides a controlled transition zone that allows the closure means to be removed and the casing to be opened without risking accidental discharge of filling material, thus preventing environmental pollution while enabling reuse.
3Reliability
If a closure means is used to seal the tubular casing, then the filling material is contained securely, but the opening process becomes more difficult and may require tools
Solution Approach 1:
The plait-like portion is pre-formed at the end of the tubular casing during manufacturing, creating a built-in opening mechanism that eliminates the need for additional tools. The closure means can be easily removed from the plait-like portion by simple pulling or twisting motions, making the opening process straightforward while maintaining secure containment during storage and transport.
