Branch Type Standing Pouch Nozzle Stability and Blockage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refill pouches face issues with nozzle blockage when dispensing high viscosity contents, unstable nozzle configurations leading to spills, increased manufacturing costs due to special members and processes, and difficulty in maintaining a compact size for efficient transportation and disposal.
Innovation Solution
A branch type standing pouch with a nozzle formed in a branched manner from the top, featuring symmetrical nozzle reinforcing areas and protrusions that allow the nozzle to be easily stood upright and maintained, reducing flow resistance and manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a nozzle portion is formed at the corner portion of the pouch, then the pouch structure is simple, but the nozzle is blocked when contents of high viscosity are poured out
Solution Approach 1:
The nozzle portion is repositioned from a corner location to the central upper portion of the pouch, changing its spatial dimension and relationship to the pouch body. This dimensional change allows the nozzle to be supported by the pouch body itself, preventing blockage while maintaining structural simplicity
2Ease of manufacture
If a nozzle portion is formed of a separated member, then the nozzle can be formed independently, but manufacturing cost and transportation cost increase
Solution Approach 1:
The nozzle portion is merged with the pouch body as an integrated structure, eliminating the need for separate nozzle components. The pouch body itself forms the nozzle through its configuration, combining the pouch and nozzle into a single manufactured unit, thereby reducing manufacturing complexity and transportation requirements
3Shape
If the nozzle portion is formed with opening and fold lines at the central portion, then the nozzle is centrally located, but the contents are spilt due to unstable configuration
Solution Approach 1:
The pouch body is designed with differentiated local qualities: the upper portion forms a rigid, triangle-shaped nozzle structure for stability, while the lower portion maintains flexibility for squeezing. This local differentiation ensures the nozzle remains stable and upright without spilling contents
4Ease of operation
If the pouch is squeezed to stand the nozzle diagonally upward, then the nozzle can be positioned upward, but the operation is unstable for children, weak women, and old persons
Solution Approach 1:
The pouch structure automatically positions the nozzle in an upright state through its own configuration and the user's simple squeezing action. The triangle-shaped nozzle structure and fold lines work together to self-correct and maintain the upright position without requiring precise diagonal squeezing, making operation stable and easy for all users

AI summary
A branch type standing pouch which includes a pouch front side member including a pouring-out nozzle backside portion which constitutes a backside of a pouring-out nozzle by being folded back and a pouch body front side portion continuous therewith; a pouch backside member constituting a backside of the pouch body; a pouring-out nozzle front side member; and a bottom member. The pouch front side member, the pouch backside member, the pouring-out nozzle front side member, and the bottom member are respectively formed of plastic film and heat-sealed to each other so that a pouring-out nozzle is formed in a branched manner from a top of a pouch body. In this pouch, two symmetrical nozzle reinforcing areas are formed on both sides of a first protrusion as a result of a provision of the first to fourth protrusions. As a result, the branch type standing pouch in which the pouring-out nozzle can be fixed upright at a time of opening is obtained.
