Solution Overview

Problem

Drinking vessels with multiple or non-planar shaped drinking openings are difficult to seal, leading to potential leakage and temperature loss when not in use.

Innovation Solution

A closure assembly comprising a positioning member and a sealing member that can be rotated into a sealing orientation to engage with the spout, compressing a sealing member between the cap and the spout to effectively seal both drinking openings, even when the spout has a curved or angled upper surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a closure assembly is used to seal multiple drinking openings, then leakage prevention is improved, but the device complexity increases

Engineering Contradiction:
Improveleakage preventionVSAvoidclosure assembly structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The closure assembly is divided into distinct functional components: a positioning member with engagement features for each drinking opening, and a sealing member with corresponding sealing surfaces. This segmentation allows each component to perform its specific function effectively while maintaining overall system reliability for sealing multiple openings.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The closure assembly is designed as a multi-functional device that can seal multiple drinking openings simultaneously. The positioning member includes multiple engagement features that can accommodate different opening configurations, while the sealing member provides corresponding sealing surfaces, allowing a single assembly to handle various spout designs (single opening, dual openings, angled, or curved) without requiring multiple different closure types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If the spout has curved or angled upper surface, then drinking convenience is improved, but sealing difficulty increases

Engineering Contradiction:
Improvedrinking convenienceVSAvoidsealing mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The sealing member is designed with sealing surfaces that specifically match the local geometry of the spout upper surface. Whether the spout has curved or angled features, the sealing member incorporates corresponding contoured surfaces that conform to these local variations, enabling effective sealing while preserving the drinking convenience benefits of the curved or angled design.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The sealing member incorporates curved or contoured sealing surfaces that match the curved or angled upper surface of the spout. This curvature matching allows the sealing member to conform to non-planar spout geometries, maintaining both drinking convenience (through preserved spout shape) and sealing effectiveness (through matching contour contact).

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A drinking vessel including a beverage container and a closure assembly attachable to the beverage container. The beverage container has a spout defining a first drinking opening and a second drinking opening. The closure assembly includes a positioning member and a sealing member. When the positioning member is in a sealing orientation, the positioning member can extend deep enough into the first drinking opening for the sealing member to seal the first drinking opening and the second drinking opening. When the positioning member is not in the sealing orientation, the positioning member cannot extend deep enough into the first drinking opening for the sealing member to seal the first drinking opening and the second drinking opening.
