Plastic insulated container with interchangeable lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic containers lack versatility and convenience in accessing and sealing liquid contents, particularly in terms of interchangeable lids that facilitate easy pouring, drinking, and storage.
Innovation Solution
A double-wall insulated plastic container with interchangeable lid assemblies, featuring removable caps with magnetic attraction, tethered caps, and rotatable spouts with sliders, allowing for various modes of access and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable cap is used to seal the spout, then the container allows easy pouring and drinking, but the cap may be lost or misplaced when removed
Solution Approach 1:
A tether acts as an intermediary element connecting the cap to the lid, allowing the cap to be removed for pouring and drinking while preventing it from being lost or misplaced. The tether serves as a mediator that maintains connection between the cap and container body during removal and reattachment operations.
2Adaptability or versatility
If multiple lid assemblies are made interchangeable with a single canister, then the container becomes more versatile for different uses, but the device complexity increases
Solution Approach 1:
The canister is designed with a universal threaded neck structure that accepts multiple different lid assemblies (drink lid, pour lid, storage lid), allowing a single container body to perform multiple functions. Each lid provides different access modes (drinking, pouring, storage) while sharing the same mounting interface on the canister.
Solution Approach 2:
The container system is segmented into a permanent canister body and removable interchangeable lids. This segmentation allows the functional elements (lids) to be separated and replaced independently while maintaining a common structural base (canister with threaded neck), reducing overall complexity compared to designing entirely different containers for each function.
3Ease of operation
If a rotatable spout with slider is used, then the container provides controlled access for drinking, but the mechanism becomes more complex
Solution Approach 1:
The spout is designed as a dynamic component that can rotate between closed and open positions, allowing controlled access to the liquid. The rotatable spout with slider mechanism provides adjustable opening/closing functionality that adapts to different user needs while maintaining a relatively simple structural implementation.

Function Achieved in This Case
Enhances convenience and versatility in accessing and storing liquid contents, providing easy pouring, drinking, and secure sealing options.
Implementation Method 1
a magnetic top surface; and a depression structure, recessed relative to the top surface. The depression structure may further comprise a magnetic surface onto which the magnetic top surface of the cap is magnetically attracted and retained

AI summary
A double-wall insulated plastic container configured to store a volume of liquid may include a lid assembly with a removable lid and cap. The plastic container may include various interchangeable removable lids. In a first example, the removable lid may have a spout opening that is sealed with a removable cap magnetically affixed to one or more surfaces of the lid or container for temporary storage while the liquid is being poured from the container. In a second example, the removable lid may include a removable cap that may be configured with a tether connected between the cap and the lid. In yet another example, the removable lid may include a slider with a rotatable spout and straw.
