Leakproof Container Adhesive Gusset Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Leakproof containers made from corrugated material face the challenge of foreign object contamination due to loose trim debris during assembly and stacking, which can contaminate the contents.
Innovation Solution
A leakproof container design featuring a blank with adhesive areas on the outer and inner end panels and corner panels that are folded to create gussets, secured by hot melt glue, preventing trim debris from entering the container and ensuring a clean, contamination-free environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If corrugated container blanks are configured to form leakproof containers with sealed corners, then fluid containment is improved, but foreign object contamination increases due to loose trim debris during assembly and stacking
Solution Approach 1:
The patent removes the problematic trim debris by extracting it from the container blank through precise die cutting and scoring lines that eliminate excess material. The blank is designed with exact dimensional specifications and clean edges, preventing any trim debris from remaining that could contaminate the container contents during assembly and stacking operations.
Solution Approach 2:
The patent applies preliminary actions by pre-scoring and pre-cutting the container blank with precise dimensions before assembly. The die cutting and scoring lines are predetermined to create clean edges and eliminate trim debris in advance, ensuring that when the container is assembled and stacked, no foreign objects can contaminate the contents.
2Object-affected harmful factors
If trim debris is removed from the container blank, then contamination is reduced, but manufacturing complexity increases due to precise die cutting and scoring requirements
Solution Approach 1:
The patent merges multiple manufacturing operations into a single integrated die cutting and scoring process. By combining the cutting of the blank shape, the creation of fold lines, and the removal of trim debris into one unified operation, the manufacturing complexity is managed more efficiently while still achieving the goal of eliminating contamination sources.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents fluid leakage and reduces contamination by ensuring a secure, trim-debris-free environment, enhancing the reliability of containers for holding moisture or fluid contents.
Implementation Method 1
The adhesive areas may be defined by an application of hot melt glue

AI summary
A leak proof container and a method of forming the container from a blank. The blank includes a bottom panel, first and second side panels connected to the bottom panel at opposing lateral edges, and first and second end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel connected to the bottom panel, an outer end panel connected to the inner end panel, and first and second corner panels forming gussets connected to a respective one of the first and second side panels and connected to the inner end panel. An adhesive area is located on one side of the blank and comprises at least a portion on each of the outer end panel and the inner end panel. The adhesive area adheres the gussets to the inner end panel and to the outer end panel.
