Lids for drinking cups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling and use of separate lids, mixing devices, and individually packaged condiments for beverages pose health risks, lead to high theft and waste, and are inconvenient and time-consuming, particularly in the context of take-away coffee culture, while also straining waste management systems due to single-use plastics.
Innovation Solution
A lid for drinking cups with a built-in mixing device that includes telescopically extendable mixing elements and a condiment holder, allowing for mixing and dispensing of condiments directly into the beverage, reducing the need for separate components and minimizing handling and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate lids, mixing devices, and individually packaged condiments are provided, then customers can access condiments and mix beverages, but health risks increase due to handling and transmission of communicable diseases
Solution Approach 1:
The patent combines the lid, mixing device, and condiment holder into a single integrated unit. The condiment is pre-loaded in the holder, and the entire assembly is disposed of after use, eliminating the need for customers to handle separate condiment packages and mixing devices, thereby reducing health risks associated with handling and transmission of communicable diseases.
Solution Approach 2:
The integrated lid and mixing device assembly is designed as a disposable item. After the condiment is dispensed and the beverage is mixed, the entire unit is discarded, eliminating the need for cleaning and reducing the risk of cross-contamination and disease transmission between customers.
2Ease of operation
If separate lids, mixing devices, and individually packaged condiments are provided, then customers can prepare beverages, but theft and wastage increase
Solution Approach 1:
By integrating the lid, mixing device, and condiment holder into one unit, the patent reduces the number of separate items that can be stolen or wasted. The condensed design makes it harder to pilfer individual components, and the pre-loaded condiment ensures that each unit is used as intended, reducing wastage.
3Ease of operation
If separate lids, mixing devices, and individually packaged condiments are provided, then beverage preparation is possible, but time consumption increases
Solution Approach 1:
The condiment is pre-loaded into the holder during manufacturing, and the entire assembly is prepared in advance. When the customer receives the beverage, they simply need to attach the lid and mix, eliminating the time-consuming steps of opening separate condiment packages and preparing mixing devices at the point of service.
4Ease of operation
If separate lids, mixing devices, and individually packaged condiments are provided, then beverage preparation is possible, but logistics complexity increases for vendors
Solution Approach 1:
The patent reduces the number of separate inventory items that vendors need to manage. Instead of stocking separate lids, mixing devices, and individually packaged condiments, vendors only need to stock the integrated units, simplifying logistics and reducing the complexity of maintaining adequate stock levels of each item.
5Ease of operation
If separate mixing devices are provided, then beverage mixing is possible, but waste management burden increases due to single-use plastics
Solution Approach 1:
By integrating the mixing device with the lid and condiment holder, the patent creates a single disposal unit. This reduces the total volume of waste compared to separate mixing devices, and the compact design facilitates more efficient waste management and recycling processes.
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
This integrated solution reduces health risks, minimizes waste, enhances convenience, and simplifies logistics for vendors by providing a single, recyclable unit that simplifies the preparation and consumption of beverages, thereby addressing the challenges of hygiene, theft, waste, and convenience in the beverage industry.
Implementation Method 1
at least two mixing elements which are displaceably connected to one another so as to be extendable in order to increase an effective length of the mixing member
Implementation Method 2
The lid cover may include an annular attachment formation for releasable attachment to a corresponding formation of the drinking cup
Implementation Method 3
a condiment holder for holding a condiment, which is integrated with one of the mixing elements, the condiment holder having at least one discharge opening through which the condiment is discharged from the condiment holder

AI summary
An open-topped drinking cup and a lid comprising a lid cover and a mixing device for holding and mixing a condiment into a beverage held in the dinking cup. The lid cover defines a circular mounting aperture within which the mixing device is displaceably located. The mixing device includes at least two mixing elements which are connected to another so as to be telescopically displaceable relative to one another between a retracted condition and an extended condition wherein the mixing device extends into the beverage. The mixing device includes a condiment chamber which is defined within a mixing element for holding a condiment such as sugar. The mixing device further includes a mixing element which has a number of circumferentially-spaced slots through which the condiment is discharged into the beverage.
