Beverage container with push sealing arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beverage containers lack a locking mechanism for the sealing handle, making it difficult for users to open and close the drinking hole, and they do not provide adequate sealing, leading to liquid spillage when the container is flipped or turned upside down.
Innovation Solution
A beverage container with a rotatable sealing arrangement featuring a cover assembly and a sealing piece that provides a double sealing effect, where the cover assembly slides to cover the access opening from the top and the sealing piece blocks from underneath, preventing liquid from spilling even when the container is inverted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sealing handle is tightly coupled to the lid body, then the sealing handle can rotate with respect to the lid body, but it is very hard for a user to rotate the sealing handle for opening and closing the drinking hole
Solution Approach 1:
The sealing handle is divided into a lid body portion and a sealing portion that can rotate relative to each other. The lid body has a recess that receives the sealing portion, allowing independent rotation of the sealing portion while maintaining the overall structural integrity for sealing.
Solution Approach 2:
A release member is introduced as an intermediary between the user and the sealing handle. The release member engages with the sealing handle and provides mechanical advantage through its lever arm, enabling users to easily rotate the sealing handle even with limited hand strength.
2Device complexity
If a conventional sealing handle is used, then the structure is simple, but there is no locking mechanism to restrict the rotational movement of the sealing handle
Solution Approach 1:
The locking mechanism is merged with the opening/closing mechanism. The release member serves dual functions: it enables rotation of the sealing handle and simultaneously locks it in position. The resilient element provides both the locking force and the mechanism for releasing the lock when actuated.
Solution Approach 2:
The resilient element automatically engages the release member with the sealing handle to maintain the locked position. The system self-locks without requiring additional components or complex mechanisms, using the inherent elasticity of the resilient element to provide continuous locking force.
3Device complexity
If conventional beverage containers are used, then they have a simple lid structure, but they do not have adequate sealing so that when the beverage container is flipped side way or turned upside down, liquid in the beverage containers may spill out of the container
Solution Approach 1:
The sealing system is segmented into multiple sealing portions: a first sealing portion on the lid body and a second sealing portion on the container body. These separate sealing surfaces work together to create a secure seal that prevents liquid leakage even when the container is inverted or tilted.
Solution Approach 2:
The sealing surfaces are designed with specific local qualities - the first sealing portion has a sealing surface that mates with a corresponding sealing surface on the container body. The recess in the lid body and the protrusion on the container body create localized sealing zones that maintain liquid containment under various orientations.

AI summary
A beverage container includes a container body, a lid having a support panel, and a push sealing arrangement. The push sealing arrangement includes a cover assembly, a main shaft and a sealing piece. The cover assembly includes a first cover. The sealing piece includes a second cover positioned underneath the first cover and the access opening. The cover assembly is arranged to move between an opened position and a closed position. In the closed position, the cover assembly is slid to drive the first cover to cover on top of the access opening, while the second cover is driven to move upwardly for blocking a bottom side of the access opening. In the opened position, the first cover is slid to expose the access opening to ambient environment, while the second cover is driven to move downwardly to allow liquid to flow out of the container body.
