Dual Overlapping Flap Closure for Simultaneous Pouring and Shaking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container closures do not efficiently allow for the simultaneous functions of shaking, pouring, and spooning products while maintaining cost-effectiveness and ease of use.
Innovation Solution
A dual overlapping flap closure system where a first flap with smaller apertures can be selectively opened or closed, and a second flap can be hingedly attached to overlay and seal the first flap, allowing for controlled dispensing through multiple states, enabling both pouring and shaking functions without requiring the user to remove the closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single flap closure is used, then the structure is simple and cost-effective, but it cannot simultaneously provide both pouring and shaking functions
Solution Approach 1:
The closure is divided into two separate flaps: a first flap for pouring and a second flap for shaking. Each flap can be independently opened or closed, allowing the user to select the desired dispensing function without requiring a complex multi-functional single flap structure.
Solution Approach 2:
The closure system provides multiple dispensing functions (pouring and shaking) through a unified closure structure. The first and second flaps work together to enable different product dispensing modes, making the closure versatile for various user needs while maintaining overall structural integration.
2Adaptability or versatility
If a dual flap system is implemented, then both pouring and shaking functions are enabled, but the manufacturing cost increases
Solution Approach 1:
By segmenting the closure into two separate flaps with distinct functions, each flap can be manufactured using standard single-flap closure designs and assembly processes. This modular approach simplifies manufacturing compared to creating a complex integrated multi-functional flap, as each component can be produced and assembled independently.
3Adaptability or versatility
If the first flap is made with small apertures, then shaking function is enabled, but the opening size is reduced which may affect pouring efficiency
Solution Approach 1:
The closure system separates the pouring function (first flap with larger opening) from the shaking function (second flap with small apertures). When the user needs to pour, they open only the first flap, providing adequate opening size for efficient pouring. When shaking is needed, they open the second flap with small apertures, enabling controlled shake dispensing without affecting the other function.

AI summary
A closure for a container having a mouth wherein the closure is adapted for sealable connection to the mouth of the container and includes an end wall at the upper end of the skirt for closing the mouth when the closure is mounted to the container. The closure includes an opening in the end wall for dispensing a product held by the container and a first flap that has at least one flap aperture that is smaller than the opening. The first flap is adapted for selectively opening and closing the opening. A second flap is adapted for overlaying the first flap and includes a first state wherein one or more of the flap apertures in the first flap are open and a second state wherein the flap apertures in the first flap are sealed.
