Drinking Bottle Closure with Segmented Clamping for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional closures for drinking bottles are difficult to clean due to their design, which often results in them being wetted by beverages, making the cleaning process cumbersome.
Innovation Solution
A closure design featuring a securing element with a pivotable clamping mechanism, a spring, and a seal that allows for easy removal and reassembly, ensuring the closure can be taken apart for cleaning without losing parts, utilizing heat-resistant food-grade plastics and silicone or TPE/TPR materials for durability and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional closure designs are used, then the closure can seal the drinking bottle, but the closure becomes difficult to clean due to beverage wetting and complex structure
Solution Approach 1:
The closure is divided into two separable clamping elements (first clamping element and second clamping element) that can be easily separated from each other. This segmentation allows the closure to be disassembled for thorough cleaning of all surfaces, including those that would otherwise be difficult to reach, while still maintaining a functional sealing structure when assembled.
Solution Approach 2:
The seal is extracted as a separate component that can be removed from the clamping elements. This allows the seal to be independently cleaned, replaced, or maintained without disassembling the entire closure mechanism, significantly improving cleaning ease while reducing the complexity of the integrated structure.
2Ease of operation
If the closure is designed for easy removal from the lid, then the closure can be easily taken apart for cleaning, but parts may be lost during the process
Solution Approach 1:
The latching elements are integrated directly into the clamping elements as integral components rather than separate parts. The first latching element is formed as part of the first clamping element, and the second latching element is formed as part of the second clamping element. This merging ensures that when the closure is disassembled for cleaning, no small separate parts can be lost, while still allowing easy removal through the reversible latching mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The closure is easy to clean, maintain, and assemble, preventing misalignment and ensuring no parts are lost during the process, while allowing for unhindered liquid flow and secure sealing.
Implementation Method 1
the spring is arranged between the two clamping elements in the direction of displacement
Implementation Method 2
a seal which is arranged on a pivot element end that pivots out

AI summary
A closure for a drinking bottle, including a securing element for releasably arranging the closure on a lid of the drinking bottle, a pretensioned pivot element which is arranged on the securing element so as to be pivotable away from said clamping element about a pivot axis, and a seal which is arranged on a pivot element that pivots out. The securing element includes a first clamping element, a second clamping element and a spring. The two clamping elements are arranged on one another so as to be linearly displaceable in one direction and the spring is arranged between the two clamping elements in the direction of displacement.
