Fluid Bag With Opposite Openings for Complete Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container bags for fluid products often struggle to empty their contents effectively, leading to economic losses due to residual product disposal, especially when complex systems with electrical, pneumatic, or hydraulic elements are used, which are costly and complicated to maintain.
Innovation Solution
A container bag design featuring two laminar bodies with through openings arranged in a specific geometry, where the shortest distances between openings on opposite sides are equal and oriented in opposite directions, facilitating effective emptying by optimizing the discharge process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If complex systems with electrical, pneumatic or hydraulic operating elements are used to empty the bag, then the emptying effectiveness is improved, but the device complexity and maintenance costs increase substantially
Solution Approach 1:
The patent extracts and removes the complex electrical, pneumatic, and hydraulic operating elements from the emptying system. Instead, it employs a simple mechanical emptying system that uses the bag's own structure (the through opening and laminar body arrangement) to achieve effective emptying through gravity and controlled discharge, thereby eliminating the need for complicated maintenance and operation systems while maintaining high emptying effectiveness
Solution Approach 2:
The patent adopts a simple, inexpensive bag structure with through openings that can be easily manufactured and replaced. Rather than investing in complex, expensive electronic or hydraulic systems that require maintenance, the solution uses a disposable or easily replaceable bag design where the emptying function is integrated into the bag structure itself, reducing long-term operational costs and complexity
2Ease of manufacture
If the bag structure is simplified to reduce manufacturing costs, then the manufacturing ease is improved, but the ability to completely empty the bag deteriorates
Solution Approach 1:
The patent segments the bag structure into two separate laminar bodies, each with its own through opening positioned on opposite sides. This segmentation allows the fluid product to flow through the interior space from one opening to the other, ensuring complete drainage. The segmented design is simple to manufacture using standard lamination and sealing techniques while effectively solving the emptying problem that single-structure bags cannot resolve
3Volume of stationary object
If the through openings are positioned closer together to reduce bag volume, then the volume is reduced, but the discharge effectiveness and emptying completeness deteriorate
Solution Approach 1:
The patent positions the through openings on opposite sides of the bag rather than close together on the same side. By utilizing the three-dimensional interior space of the bag and arranging openings in opposite directions, the design ensures that fluid can drain completely from all regions of the bag interior. This spatial arrangement maintains optimal discharge effectiveness while efficiently utilizing the bag's volume capacity

AI summary
The invention relates to a bag for containing fluid products, comprising a first laminar body and a second laminar body, wherein each laminar body has an opening; and said openings are arranged in a mutual relative position that fulfils the property where the shortest rectilinear distance D1 between both openings measured along the outer contour and starting at one of the openings, and therefore on the respective side of the outer contour, is equal to the shortest rectilinear distance D2 between both openings measured along the outer contour and starting at the other opening, and therefore on the other opposite side of the same outer contour, where the measurement of the other distance D1 began, and the measurement of the distance D2 also starts in one direction and is oriented in the opposite way to the measurement of the distance D1.
