Lid comprising drinking closure for a drinking vessel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking vessel lids with integrated drinking spouts require a thin drinking tube for consumption, which is inconvenient and requires more cleaning effort, and the design restricts direct drinking due to the limited pivot range of the closure cap.
Innovation Solution
A lid with a laterally bent or curved pivot arm and a laterally offset drinking spout, allowing for easy opening and closing without a drinking tube, enabling unhindered drinking and reduced interference during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a straight linear pivot arm with closure cap is used, then the drinking opening can be closed, but the drinking tube must be thin which requires greater cleaning effort and cannot be omitted due to limited pivot range
Solution Approach 1:
The pivot arm is designed with a lateral bend or curve instead of being straight, allowing the closure cap to clear the drinking opening path without requiring a thin drinking tube. This curved geometry enables the pivot arm to rotate through the necessary range while maintaining structural integrity and eliminating the need for a separate drinking tube component.
Solution Approach 2:
The drinking spout is positioned laterally offset from the hinge axis, creating a three-dimensional arrangement where the closure cap approaches the drinking opening from a different spatial dimension. This lateral offset allows the pivot arm to open the drinking spout without interference, eliminating the need for a thin drinking tube while maintaining effective closure functionality.
2Device complexity
If the pivot arm is made straight, then the structure is simpler, but the drinking process is hindered as the person bumps against the pivot arm with nose
Solution Approach 1:
The laterally bent or curved pivot arm design allows the closure cap to follow a curved trajectory during rotation, clearing the direct path to the drinking opening. This curvature prevents the closure cap from obstructing the user's nose during drinking while maintaining structural simplicity through a single-piece molded construction.
Solution Approach 2:
The pivot arm features asymmetric geometry with a lateral bend that creates an uneven rotation path. This asymmetric design allows the closure cap to approach the drinking opening from an offset angle, avoiding direct contact with the user's face during the drinking process while maintaining effective sealing capability.
3Device complexity
If the hinge is positioned centrally, then the lid structure is simpler, but the closure cap cannot open the drinking spout without interfering with drinking
Solution Approach 1:
The drinking spout is positioned laterally offset from the hinge axis rather than being centrally aligned. This lateral displacement creates a rotational path that allows the closure cap to open the drinking spout without blocking the user's access to the opening, solving the interference problem while maintaining a relatively simple hinge-based structure.
Solution Approach 2:
The lid structure features localized functional zones with different properties: the hinge area provides rotational support while the laterally offset drinking spout area provides unobstructed access. This spatial differentiation of functional qualities allows both simple structure and effective operation to coexist.

AI summary
The invention relates to a lid with drinking closure (5) for a drinking vessel (15) that includes an upwardly curved cover element (1), which internally comprises a screw thread (16) for connection with the drinking vessel (15) and comprises a drinking opening (2) with an upwardly oriented round drinking spout (6), whereby a hinge (3) is arranged on the upper cover surface (14) of the cover element (1) and is connected with a pivot arm (7) with a closure cap (8), and which closes the drinking spout (6) in a form-fitting manner upon downward pivoting. The invention is characterized in that the drinking opening (2) with the drinking spout (6) is arranged laterally offset relative to a straight line (11) through the hinge center (13) and the center point (12) of the cover element (1), and in that the pivot arm (7) is laterally bent or curved from the hinge (3) to the drinking spout (6).
