Dual-Opening Beverage Lid With Pivot Closure for Spill Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beverage containers are unsuitable for use during exercise or travel due to their tendency to spill, difficulty in opening and closing, and limited portability, making them inconvenient for consuming liquids on the go.
Innovation Solution
A container with a lid that features a threaded or screw-type connection for easy attachment, a watertight seal, and a lever mechanism for effortless opening and closing, along with multiple openings for pouring and drinking, including a spout and straw option for flexible use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a watertight or airtight seal is used between the cover and the drinking aperture to prevent spilling, then the container prevents beverage from spilling, but substantial effort is required to open and close the cover
Solution Approach 1:
The closure is divided into a cover portion and a closure portion that can move relative to each other. The cover remains stationary maintaining the seal, while the closure portion pivots to open/close the aperture. This segmentation allows the seal to remain intact while reducing the force needed to operate the opening mechanism.
Solution Approach 2:
The closure portion is made movable relative to the cover portion through a pivoting mechanism. This dynamic element allows the closure to transition between open and closed positions without requiring substantial force, as the pivot point provides mechanical advantage while maintaining the watertight seal when closed.
2Productivity
If the cover is opened suddenly and abruptly to allow drinking, then the user can quickly access the beverage, but some of the contents may spill
Solution Approach 1:
The gradual opening mechanism allows the closure portion to pivot slowly from the closed to open position, enabling controlled beverage flow. This dynamic movement prevents sudden release of contents while still allowing quick access to the beverage, maintaining both speed and spill prevention.
Solution Approach 2:
The closure portion acts as a temporary barrier that can be quickly deployed and repositioned. Unlike a permanent sealed cover, this disposable-style closure can be opened, used, and reclosed multiple times without compromising the seal, allowing rapid repeated access without spillage.
3Reliability
If a small cover is used over the drinking aperture to prevent spilling, then the container prevents contents from spilling, but the cover is difficult to securely close
Solution Approach 1:
The closure system is segmented into a stationary cover and a movable closure portion. The cover provides the seal structure while the closure portion provides the operable element. This division allows the sealing function to be maintained while the operating element becomes easier to manipulate and secure.
Solution Approach 2:
The closure mechanism is designed to be self-latching through the pivoting action. When the closure portion is pushed to the closed position, the geometry of the pivot mechanism automatically maintains the closed state without requiring additional securing actions from the user, making it easy to securely close.
4Adaptability or versatility
If multiple openings are provided in the lid for pouring and drinking, then the container allows flexible use for pouring and sipping, but the lid structure becomes more complex
Solution Approach 1:
The lid is designed with multiple openings that serve different functions: one opening for pouring and another for drinking with a straw. This multi-functionality allows a single lid structure to handle both pouring and sipping needs, providing versatility without requiring separate components for each function.
Solution Approach 2:
Multiple openings and their associated closure mechanisms are merged into a single integrated lid assembly. Rather than having separate removable covers for each opening, the design combines them into one unified structure where each opening has its own closure portion, reducing overall complexity while maintaining versatility.

AI summary
A lid may include first and second openings disposed within a spout. The first opening may provide a first fluid pathway to a fluid disposed in an attached container and the second opening may provide a second fluid pathway to a fluid disposed in the container. The lid may also include a spout at least partially defined by an outer wall. First and second openings may be disposed within the spout and the openings may be at least partially defined by the outer wall of the spout. A conduit, such as a straw, may be coupled to an opening. If desired, a closure may be connected to the lid and the closure may selectively close one or more of the openings.
