Reusable Bottle Package Snap-Fit Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle packages for cosmetics lack sustainability and user-friendly reusability, as they do not allow for easy replacement and recycling of inner containers, leading to inefficiencies in product use and waste generation.
Innovation Solution
A reusable bottle package design featuring a snap-fit mechanism with a push-to-release button that secures and releases the inner bottle assembly from the outer bottle assembly, enabling easy replacement and recycling, using either a pliable or rigid button to disengage the snap feature, allowing for continuous use of the pump engine and outer bottle while the inner bottle is made disposable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional bottle package design is used, then the structure is simple, but the bottle cannot be reused and generates waste
Solution Approach 1:
The bottle package is divided into separate reusable and disposable components. The outer bottle, pump engine, and cap form a reusable outer assembly, while the inner bottle with cosmetic product forms a disposable inner assembly. This segmentation allows the reusable portion to be retained and refilled, reducing waste while maintaining a manageable package structure through modular design.
Solution Approach 2:
The inner bottle assembly is nested within the outer bottle assembly. The inner bottle containing the cosmetic product is placed inside the outer bottle that contains the pump engine and dispensing mechanism. This nesting arrangement allows for compact packaging, easy assembly, and enables the reusable outer assembly to protect and house the disposable inner assembly, facilitating reuse without excessive complexity.
2Ease of manufacture
If the inner bottle is made disposable for easy replacement, then waste is reduced through recycling, but the connection mechanism becomes more complex
Solution Approach 1:
The connection mechanism is extracted as a separate functional element between the inner and outer assemblies. The outer bottle includes a rim with engagement features, while the inner bottle has a corresponding base with matching engagement features. This extracted connection mechanism allows for tool-free attachment and detachment, making replacement easy for consumers while maintaining a structured connection system that isn't overly complex.
Solution Approach 2:
The connection mechanism is designed to be self-servicing through push-to-release buttons that automatically disengage the snap-fit connections. When the release buttons are pressed, the inner bottle assembly automatically detaches from the outer bottle assembly without requiring manual manipulation or special tools. This self-service feature simplifies the replacement process for users while the underlying snap-fit mechanism provides reliable connection.
3Ease of operation
If a snap-fit mechanism is used to secure the inner bottle, then the release mechanism becomes simpler, but the user friendliness decreases
Solution Approach 1:
Push-to-release buttons serve as intermediary elements between the user and the snap-fit connection mechanism. These buttons are strategically positioned on the outer cap and outer bottle, providing an intuitive and easy-to-operate interface for users. When pressed, these intermediary buttons trigger the disengagement of the snap-fit connections, allowing easy release of the inner bottle assembly. This intermediary mechanism enhances user friendliness while the underlying snap-fit structure maintains simplicity.

AI summary
A reusable bottle package includes an inner bottle, an inner base coupled to the inner bottle, an outer bottle, an outer base coupled to the outer bottle, and a push-to-release button contained by the outer base. The outer base cooperates with the inner base to form at least one snap feature. The inner bottle is secured to the outer bottle when the at least one snap feature is engaged. The at least one snap feature becomes disengaged when the push-to-release button is depressed, thereby allowing the inner bottle to be removed from the outer bottle.
