Leak Proof Container Push Lock Body Rollover Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leak-proof containers made from corrugated material face issues with foreign object contamination due to trim debris and difficulty in secure assembly, as they can be prone to leakage and require precise setup to maintain the lock.
Innovation Solution
A leak-proof container design featuring a blank with specific folding patterns and locking mechanisms, including corner panels with notches and hinge portions, and locking tabs that engage with gussets to secure the assembly, reducing the risk of contamination and ensuring easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If corrugated material is used to form leak-proof containers, then fluid leakage is prevented, but foreign object contamination occurs due to trim debris
Solution Approach 1:
The patent removes the problematic trim areas from the container design by using a seamless blank formation process. The container is formed from a single piece of corrugated material without internal trim or overlap areas, eliminating the source of contamination debris while maintaining the leak-proof properties of the corrugated structure.
Solution Approach 2:
The blank is divided into specific panels (bottom panel, side panels, end panels, corner panels) that are formed and connected in a predetermined sequence. This segmentation allows each panel to be optimized for its function while ensuring no trim debris is generated during assembly, as all connections are formed from the original blank structure.
2Reliability
If self-locking design is used in containers, then assembly security is improved, but assembly difficulty increases and secure assembly may not be maintained
Solution Approach 1:
The blank is pre-configured with score lines, fold lines, and panel arrangements that guide the assembly process. The corner panels, side panels, and end panels are positioned and connected in a predetermined sequence during formation, so that the locking structure is established automatically as the container takes shape, reducing the need for complex manual locking operations.
Solution Approach 2:
The container structure is designed to lock itself through the interlocking of panels formed from the blank. The corner panels and end panels naturally engage with each other through the predetermined fold lines and connections, creating a self-locking mechanism that maintains assembly security without requiring additional fastening operations or complex manual intervention.
3Ease of manufacture
If traditional container construction is used, then manufacturing is simpler, but contamination risk increases due to trim debris
Solution Approach 1:
The patent eliminates the trim debris generation step by forming the container from a seamless blank that requires no internal trimming or overlapping operations. The entire container structure, including corner panels and end panels, is formed from the original blank material, removing the source of contamination while maintaining manufacturing efficiency.
Solution Approach 2:
The container is formed as a unified structure from a single blank of corrugated material, merging all panels and connections into one continuous formation process. This eliminates the need for separate trimming, cutting, or assembly operations that would generate debris, while the corrugated structure itself provides both strength and leak-proof properties.

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 at opposing lateral edges of the blank, and opposing end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel, an outer end panel hingedly connected to the inner end panel at hinge portions, and first and second corner panels, each corner panel forming a gusset between one of the side panels and the inner end panel, each gusset including a notch area for receiving one of the hinge portions. First and second locking tabs are defined in the outer end panel. The outer end panel can be folded over the inner end panel to position the hinge portions in the notch areas, and the locking tabs can be positioned between the gussets and the inner end panel.
