Bag-In-Box Packaging With Removable Top Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bag-in-box packaging requires positioning at the edge of a table for dispensing, limiting user options and creating isolated pockets of liquid as the bag collapses, necessitating gravity-based dispensing.
Innovation Solution
A bag-in-box packaging design with a removable top wall and hinged flaps, allowing for use with a pressure-assisted dispensing device, enabling the bag to be positioned inverted with the tap at the top and ensuring complete dispensing without gravity reliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tap is located near the bottom of the bag-in-box packaging for gravity-based dispensing, then the dispensing mechanism is simple, but the packaging must be positioned at the edge of a table which limits user options
Solution Approach 1:
The patent inverts the conventional dispensing configuration by positioning the tap at the top of the packaging instead of the bottom. This allows the packaging to be placed on a table surface rather than at the edge, providing positioning flexibility. The inversion is้ ๅ with pressure-assisted dispensing to overcome gravity's role in conventional bottom-tap designs.
2Productivity
If the bag collapses upon itself as liquid is withdrawn, then the structure is simple, but pockets of liquid are isolated from the tap and cannot be withdrawn
Solution Approach 1:
The patent segments the bag structure into multiple chambers or compartments that can be independently collapsed. This segmentation prevents the formation of isolated liquid pockets by ensuring that liquid pathways remain open to the tap as each chamber collapses sequentially, enabling complete dispensing of all contents.
3Adaptability or versatility
If pressure-assisted dispensing is used to enable inverted configuration with tap at top, then positioning flexibility is improved, but the device complexity increases
Solution Approach 1:
The patent designs a pressure-assisted dispensing device that can function in multiple configurations - both inverted with tap at top and conventional positions. This multi-functionality provides positioning versatility while managing device complexity by using a single integrated pressure mechanism that adapts to different orientations and dispensing modes.

AI summary
A bag-in-box packaging includes an outer box, a collapsible inner box disposed within an interior of the outer box, and a dispensing tap coupled to the inner bag. The outer box includes a side wall, a tap access feature formed in the side wall, and a removable top wall. The top wall includes overlapping first and second top flaps. The first top flap is hingedly connected to a front side of the side wall along a first tear line. The second top flap is hingedly connected to a rear side of the side wall along a second tear line. The rear side of the side wall is disposed opposite the front side. The top wall is separable from the side wall along the first and second tear lines.
