Bag-like Container Spout with Linear Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag-like containers with spouts for liquid food require separate pouring and filling spouts, leading to complex manufacturing, increased costs, and hygiene issues due to contact between contents and sealing mechanisms, as well as difficulties in disposal and transportation.
Innovation Solution
A bag-like container with a spout featuring a plastic linear fastener that separates the contents spout from the unsealing area, using a projecting and recessed part that is cut off from the internal space to maintain liquid-tightness and prevent contamination, allowing for uncomplicated and sanitary supply and resealing without additional sealing implements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate pouring and filling spouts are provided, then the container can perform both pouring and filling functions, but the manufacturing process becomes complicated and costs increase
Solution Approach 1:
The patent merges the pouring spout and filling spout into a single integrated spout structure. The spout includes both a pouring outlet and a filling inlet formed as one piece, eliminating the need for separate components and simplifying manufacturing while maintaining both pouring and filling functionalities.
Solution Approach 2:
The spout is designed as a multi-functional component that serves both pouring and filling purposes. The single spout structure incorporates multiple functions (pouring, filling, and potentially sealing) within one integrated element, reducing the overall number of components needed in the container system.
2Adaptability or versatility
If separate pouring and filling spouts are provided, then the container can perform both pouring and filling functions, but costs increase
Solution Approach 1:
The patent merges the pouring spout and filling spout into a single integrated spout structure. The spout includes both a pouring outlet and a filling inlet formed as one piece, eliminating the need for separate components and simplifying manufacturing while maintaining both pouring and filling functionalities.
3Ease of operation
If contents contact the sealing mechanism during unsealing, then the sealing can be opened, but hygiene is compromised due to potential contamination
Solution Approach 1:
The patent segments the spout into distinct functional zones: a sealed portion that maintains sterility, an unsealing portion that can be opened, and a contents-holding portion. This segmentation allows the sealing mechanism to be isolated from direct contact with contents during unsealing operations, maintaining hygiene while enabling easy opening.
Solution Approach 2:
The patent introduces an intermediary sealing mechanism (such as a zipper or snap-fit closure) that mediates between the sealed contents and the external environment. This intermediary allows controlled unsealing without direct contact between contents and the sealing surfaces, preventing contamination while enabling easy opening.
4Adaptability or versatility
If the pouch is cut and sealed using a zipper-type mechanism, then the pouch can be opened and closed, but the manufacturing process becomes complicated
Solution Approach 1:
The patent combines the sealing function with the spout structure itself. The sealing mechanism is integrated into the spout body rather than being a separate component, simplifying the overall structure while maintaining openable and closeable functionality. The spout and sealing mechanism are formed as one piece.

AI summary
A bag-like container with a spout in which a plastic linear fastener is interposed in an upper part of the container so that when water content or the like is to be supplied after contents of a liquid food container or the like have been administered to a subject, opening and closing the linear fastener enables the water content or the like to be supplied in an uncomplicated manner without the use of a separate member such as a spout that is an open part for pouring food, water, or the like into the container.
