Two-Piece Bliss Container Sloped Interior Bottom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bliss-type container designs lack the necessary strength and stability to efficiently carry and dispense liquid or flowable products, particularly due to their flat interior bottom walls which do not facilitate easy product release.
Innovation Solution
A two-piece bliss container design featuring a sloped interior bottom wall is created by combining a liner blank and a body wrap blank, constructed from formable materials like cellulose-based or polymer materials, with specific folding and scoring patterns to form a container that allows for easy product dispensing and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat interior bottom wall is used in conventional bliss-type containers, then the manufacturing process is simple, but the container lacks strength and stability and does not facilitate easy product release
Solution Approach 1:
The container is divided into two separate blanks (liner blank and body wrap blank) that are assembled together. The liner blank forms the interior bottom panel with slope while the body wrap blank forms the exterior, allowing each component to be optimized independently for both manufacturing simplicity and structural strength.
Solution Approach 2:
The interior bottom panel is designed with a sloped configuration rather than a flat surface. This curvature facilitates easy product release and improves container strength and stability while maintaining manufacturing simplicity through the two-piece blank design.
2Device complexity
If a flat interior bottom wall is used in conventional bliss-type containers, then the structure is simple, but the container does not facilitate easy product dispensing
Solution Approach 1:
The interior bottom panel incorporates a slope that guides liquid or flowable products toward the discharge opening. This curved/sloped surface design facilitates easy product dispensing while the two-piece blank construction maintains reasonable structural complexity.
Solution Approach 2:
The slope is applied specifically to the interior bottom panel where product flow is needed, while other portions of the container maintain simpler geometry. This localized application of complexity optimizes product dispensing without unnecessarily increasing overall structural complexity.
3Ease of operation
If a sloped interior bottom wall is implemented, then product release is improved, but the manufacturing process becomes more complex
Solution Approach 1:
By separating the container into two blanks, the sloped interior bottom panel can be formed in the liner blank independently. This segmentation allows the complex sloped geometry to be manufactured separately and then assembled, reducing overall manufacturing complexity compared to forming the slope in a single-piece container.

AI summary
A two-piece bliss-type container blank and resulting container for easily dispensing products contained within is disclosed. Specifically, the container is designed to have an exterior bottom panel that is essentially flat, while having an internal bottom panel that is inclined toward a front panel. The front panel includes structure to permit the removal of product from within the container. The two-piece bliss-type structure provides a strong and stable container that may be constructed to varying sizes and geometries.
