Dual Hinge Flip Cap Closure for Flexible Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional dispensing closures with multiple flaps do not allow for a fully open dispensing option, limiting user flexibility in dispensing products from containers.
Innovation Solution
A dual hinge flip cap closure system that includes a skirt and a top connected via a first hinge, with a lid attached via a second hinge, allowing for full-open or less-than-full-open dispensing capabilities by opening at opposite angles, and featuring indented portions and tabs for easy identification and locking mechanisms for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional dispensing closures incorporate multiple flaps with different sizes or styles of openings, then users can dispense products at different rates, but a fully open dispensing option is precluded
Solution Approach 1:
The closure is divided into multiple functional segments: a top portion with a first hinge for partial opening, and a lid portion with a second hinge for full opening. This segmentation allows each portion to serve different dispensing needs - the top provides controlled dispensing when partially opened, while the lid enables full-open dispensing when opened completely, thus resolving the contradiction between versatility and full-open capability.
Solution Approach 2:
The closure employs dynamic hinge mechanisms that allow the top and lid to move independently between multiple positions. The first hinge enables the top to rotate to a first position for controlled dispensing, while the second hinge enables the lid to rotate to a second position for full-open dispensing. This dynamic capability allows the closure to adapt between different dispensing modes, achieving both versatility and full-open capability.
2Adaptability or versatility
If a dual hinge system is implemented to provide full-open and controlled dispensing options, then dispensing versatility is improved, but device complexity increases
Solution Approach 1:
The closure merges multiple functions into a single integrated structure. The top and lid portions are combined in one closure assembly, with both hinge mechanisms integrated into the same structure. This merging allows the closure to provide both controlled and full-open dispensing capabilities without requiring separate closure devices, thus improving versatility while managing complexity through integration.
Solution Approach 2:
The closure is designed as a multi-functional device where the same structure serves multiple purposes: the top portion with its hinge provides controlled dispensing functionality, while the lid portion with its hinge provides full-open dispensing functionality. This universality allows a single closure device to replace what would traditionally require multiple separate components, achieving versatility without proportionally increasing complexity.

AI summary
The disclosed aspects relate to a dual hinge flip cap closure. The closure includes a skirt that operatively engages a container. The closure also includes a top connected to the skirt at a first hinge, wherein the top is movable relative to the skirt. Further, the closure includes a lid operatively attached to the top at a second hinge, wherein the lid is movable relative to the top, and wherein a distal end of the lid is at an opposite of the top relative to the first hinge and the second hinge is between the first hinge and the end of the lid.
