Reclosable Container Lid Guide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flip top containers with hinged lids often face difficulties in re-closing due to obstruction by internal elements, making reliable reclosing inefficient.
Innovation Solution
A reclosable container design featuring a sloping division line on the side panels and a downwardly extending flap from the inner front part, guiding the lid during rotation to prevent unintended engagement with internal components, combined with a pre-provided folding line in the rear panel for easier closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hinged lid is used in a flip top container, then the container can be opened and closed, but the reclosing operation becomes obstructed by internal elements
Solution Approach 1:
A guide element is introduced as an intermediary component between the lid and the container body. This guide element actively directs the lid's movement path during closing, preventing obstruction by internal elements and ensuring reliable engagement with the closure surface.
Solution Approach 2:
The guide element is pre-positioned within the container structure to anticipate and prevent potential obstruction issues before they occur. By having the guide element in place beforehand, the lid is steered along the correct path from the start of the closing motion, eliminating the need for corrective actions during closure.
2Productivity
If the lid is rotated towards closing position, then the container can be closed, but internal elements block the passage of the lid
Solution Approach 1:
The guide element serves as a mediator that facilitates smooth lid movement by preventing direct contact between the lid and obstructing internal elements. This intermediary structure enables efficient closing operations without interference from container contents.
3Adaptability or versatility
If internal elements are placed inside the container, then the container can hold contents, but these elements obstruct the lid's closing path
Solution Approach 1:
The guide element acts as a mediator that allows both functions to coexist: the container can hold internal elements while maintaining reliable closure. The guide element creates a dedicated path for the lid that is independent of the internal elements, ensuring closure reliability regardless of container contents.

AI summary
The present invention relates to a reclosable container comprising a bottom panel, a front panel, two side panels, a rear panel and a top panel. The front panel and the two side panels having a division line extending downwardly sloping from the rear panel in the side panels and horizontally in at least a part of the front panel thereby defining a lid. The lid comprises the top panel and the sections of the front panel and side panels above the division line, and the lid is moveable by rotation along a folding line in the rear panel between a closing position, where the lid closes the container, and a position where an open end of the container is not covered by the lid. The container further comprises an inner side part and an inner front part extending above the division line. Each inner side part has an upper margin sloping downwardly towards the rear panel The inner front part comprises a flap extending downwardly from an upper margin of the inner front part.
