Leakproof Container with Push Lock Body and Trimless Corner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leakproof containers made from corrugated material face contamination issues due to potential foreign object contamination from trim debris, which can fall between stacked containers during manufacturing and contaminate the contents.
Innovation Solution
A leakproof container design featuring a blank with specific folding patterns and locking tabs that prevent trim debris from entering, including a bottom panel with side panels connected at opposing edges, end portions with inner and outer panels hingedly connected, and corner panels folded to create gussets that are locked by tabs to prevent fluid leakage and debris entry.

Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional corrugated container blanks are used with standard corner sealing, then the container can be manufactured and assembled, but trim debris can fall between stacked containers and contaminate the contents
Solution Approach 1:
The corner panel is divided into multiple segments including a first corner panel portion, a second corner panel portion, and a trimless corner panel portion. This segmentation allows the trim to be positioned in a dedicated external area rather than potentially falling into the container interior, thus preventing contamination while maintaining structural integrity.
Solution Approach 2:
The trim is extracted from the interior space to an exterior position on the container blank. By positioning the trim on the outer surface and securing it with adhesive, the potential source of contamination is removed from the interior environment, preventing debris from falling between stacked containers.
2Reliability
If the container blank includes additional panels and locking mechanisms, then leakproofing and debris prevention are improved, but the manufacturing complexity increases
Solution Approach 1:
Multiple functions are merged into the corner panel structure. The corner panel serves both as a structural connector between side and end panels and as a leakproof sealing mechanism through its folded configuration. The adhesive layer combines joining and sealing functions in one element, simplifying the overall assembly process despite the increased structural complexity.
Solution Approach 2:
The container blank is designed to be self-assembling through its pre-configured fold lines and adhesive placements. The structure naturally guides the assembly process without requiring complex external tooling or multi-step procedures, making the increased structural complexity manageable in manufacturing.

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, each corner panel having an edge connected to a respective one of the first and second side panels and having an edge connected to the inner end panel. First and second locking tabs are defined in the outer end panel, each locking tab being defined by a lateral separation line located longitudinally inward from an outer longitudinal edge of the outer end panel and extending laterally to define a free tab end.
