Cylindrical Container Inner Pouch Support for Complete Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cylindrical container inner bags are prone to bending and tilting within the container, leading to incomplete filling and potential rupture due to the weight of the filler, necessitating manual adjustment to center the bag's bottom.
Innovation Solution
A cylindrical container inner bag with a support mechanism, including a bar-shaped support member, regulates the position of the bag's bottom within the container, ensuring it remains centered and preventing bending during filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inner bag is made with width equal to half the inner circumferential length of the cylindrical container, then the inner bag can be inserted into the container, but the inner bag bends and tilts during filling, preventing complete filling
Solution Approach 1:
The bottom of the inner bag is pre-formed with a curved shape matching the cylindrical container's bottom curvature. This preliminary shaping ensures that when the bag is inserted and filled, the bottom naturally conforms to the container without bending or tilting, enabling complete filling without manual adjustment.
2Quantity of substance
If the inner bag is filled to the same capacity as the cylindrical container, then the container capacity is fully utilized, but the films may be stretched and ruptured due to the weight of the filler
Solution Approach 1:
The bottom portion of the inner bag is formed with a curved shape that matches the cylindrical container's bottom, creating a localized structural feature that distributes the weight of the filler evenly across the bottom surface. This local quality enhancement prevents concentrated stress that could cause film rupture while enabling full capacity filling.
3Productivity
If manual lifting and adjustment of the inner bag is performed to center the bottom, then the inner bag can be fully filled, but the process increases complexity and risk of film rupture
Solution Approach 1:
The bottom of the inner bag is pre-formed with a curved shape that automatically centers it on the cylindrical container's bottom during insertion. This preliminary geometric configuration eliminates the need for manual lifting and adjustment operations, simplifying the process while ensuring complete filling.

AI summary
Provided are a cylindrical container inner bag (1) and a composite container using the cylindrical container inner bag (1) for the purpose of easily filling the cylindrical container inner bag (1) housed in a cylindrical container with a filler to the substantially same capacity as that of the cylindrical container without the need for the process of lifting the cylindrical container inner bag (1) filled with the filler to unbend the bottom of the cylindrical container inner bag (1) and adjusting the position of the bottom (8) of the cylindrical container inner bag (1) onto the vicinity of the center of the bottom of the cylindrical container. The cylindrical container inner bag (1) formed in such a manner that one or more films (2) folded back or overlapping with each other are closed at least at a right or left end portion (3) or a lower portion (4) has a filler housing portion (5) and a support mechanism portion (6) positioned below the filler housing portion. The support mechanism portion (6) has a support mechanism (7) configured to regulate the position of the bottom (8) of the inner bag in a cylindrical container.
