Solution Overview

Problem

Existing multiple chamber containers often discharge unmixed components, leading to discomfort or harm to patients due to the lack of a mechanism to ensure correct sequential opening of peel seals, allowing unmixed components to be dispensed.

Innovation Solution

A multiple chamber container design featuring a first peel seal with a lower peel seal force than a second peel seal, where the second peel seal is activated only after the first, ensuring that components are thoroughly admixed before being dispensed through the outlet, utilizing a symmetrical chamber geometry and varying peel seal forces and activation energies to facilitate correct sequential opening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single peel seal is used to separate chambers, then the structure is simple, but unmixed components may be dispensed through the outlet

Engineering Contradiction:

Improveprevention of unmixed component dispensingVSAvoidnumber of peel seals

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The single peel seal is divided into two separate peel seals: a first peel seal that separates the chambers and a second peel seal that isolates the outlet. This segmentation ensures that components must be mixed before the outlet can be accessed, preventing dispensing of unmixed components while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #1Segmentation

2Reliability

If peel seal forces are made equal, then the seals open simultaneously, but correct sequential opening cannot be ensured

Engineering Contradiction:

Improvecorrect sequential openingVSAvoidvarying peel seal forces

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The first and second peel seals are designed with different peel seal forces tailored to their specific functions. The first peel seal has a lower force for initial chamber separation, while the second peel seal has a higher force to ensure it opens only after mixing is complete, guaranteeing correct sequential opening through localized force differentiation.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If the second peel seal has lower activation energy, then it opens easier, but unmixed components may be dispensed

Engineering Contradiction:

Improveease of seal activationVSAvoidprevention of unmixed component dispensing

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The activation energy and peel seal force parameters are specifically differentiated between the two seals. The second peel seal is designed with higher activation energy and higher peel seal force than the first seal, ensuring it can only be activated after the first seal opens and mixing occurs, thus preventing dispensing of unmixed components while maintaining ease of operation through proper parameter sequencing.

AI summary

The present disclosure provides a multiple chamber container that includes a container body sealed around a peripheral edge and having an outlet. The container also includes a first peel seal having a projecting portion and a second peel seal that isolates the outlet. The second peel seal may also include a projecting portion. The first and second peel seals may be configured to define a symmetrical chamber. The chamber may include an axis of symmetry extending between the first and second projecting portions. The chamber geometry of the container ensures a correct sequential opening of the first and second peel seals.
