Multi-chamber Container with Segmented Lid for Freshness and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container and lid systems lack flexibility and security features, as they often require multiple lids for multi-chamber applications and do not allow for individual prefilling of compartments, which can impact the rim closure and compromise the freshness of contents.
Innovation Solution
A multi-chamber container design featuring a main container with a level rim, inner containers with flat rim sections, and a main lid with a lower skirt section for secure attachment, allowing for individual compartment filling and sealing, with minimal impact on the rim closure and providing tamper-evidence through adhesive tape or shrink-wrapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple lids are used for multi-chamber applications, then each chamber can be sealed, but the device complexity increases and flexibility is reduced
Solution Approach 1:
The patent combines multiple sealing functions into a single lid structure. The lid includes a first portion that seals the main container opening and a second portion that forms a compartment with an opening, allowing one lid to perform multiple sealing functions that would traditionally require separate lids for each chamber.
Solution Approach 2:
The lid is designed with multi-functionality to serve different purposes: it seals the main container, creates a separate compartment for additives, and provides individual sealing capability through its first and second portions. This universal design eliminates the need for multiple specialized lids.
2Reliability
If compartments are pre-filled with additives, then freshness is maintained, but the ability to select desired amount is reduced
Solution Approach 1:
The lid is segmented into distinct portions: a first portion for sealing the main container and a second portion forming a separate compartment. This segmentation allows the compartment to be pre-filled with additives while maintaining the ability to control the amount added to the main container by removing only the necessary portion.
Solution Approach 2:
The lid design allows dynamic interaction where the first and second portions can be removed independently or together based on user needs. This dynamic capability enables users to select the desired amount of additive material while maintaining freshness during transport and storage.
3Reliability
If adhesive tape or shrink-wrapping is used for tamper-evidence, then security is improved, but the device complexity increases
Solution Approach 1:
The patent employs disposable sealing elements such as adhesive tape or shrink-wrapping that are applied to the lid or container opening. These single-use security features provide tamper-evidence without requiring complex mechanical locking mechanisms, adding minimal complexity while enhancing security.

AI summary
A multi-chamber container is provided having a main container and a main lid. The main container is configured to receive a first inner container which rests on the rim section of the main container. An optional cover for the first inner container is typically provided. A second inner container is releasably attached to, and held to, the lower surface of the main lid by an inner attachment section. The main container is sealed by a skirt section on the main lid so that the contents within the main container, the first inner container, and the second inner container, are only accessible when the lid has been detached from the container, and the first and second containers have been removed. A low cost, easily assembled, secure, single-use, multi-chamber container is provided.
