Spray Dispenser Hinged Closure and Actuator Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol spray dispensers for personal care products lack user-friendly designs for easy replacement of cartridges and accidental actuation prevention, and they do not effectively display the type of contents within the dispenser.
Innovation Solution
A compact, portable spray dispenser with a hinged closure and latch mechanism for easy cartridge replacement, an actuator lock to prevent accidental actuation, and a viewing window to identify the contents, allowing users to see external markings on replaceable aerosol canisters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional sealed aerosol dispenser is used, then the product is protected from accidental actuation, but the cartridge cannot be easily replaced and the contents cannot be identified
Solution Approach 1:
The dispenser is divided into a reusable housing and replaceable cartridges, allowing easy cartridge replacement while maintaining the sealed protection of the housing. The hinged closure provides a clear opening for cartridge insertion and removal while maintaining security during use.
Solution Approach 2:
A hinged closure acts as an intermediary mechanism between the user and the cartridge compartment. It provides a controlled interface for cartridge replacement while maintaining the sealed protection of the dispenser body, preventing accidental actuation.
2Loss of information
If a viewing window is added to the housing, then the contents can be identified, but the device complexity increases
Solution Approach 1:
The viewing window utilizes the transparency or color properties of the housing material to provide visual identification of cartridge contents. This simple optical property allows users to identify contents without adding complex mechanical or electronic systems.
3Reliability
If an actuator lock mechanism is added, then accidental actuation is prevented, but the device complexity increases
Solution Approach 1:
The actuator lock mechanism is designed to automatically engage and disengage based on the natural movement of the actuator button. The spring-loaded latch portion self-activates when the button is pressed, eliminating the need for separate locking mechanisms or complex control systems.

AI summary
Spray dispensers and body spray systems are provided. The spray dispensers are suitable for use with aerosol personal care compositions, e.g., body sprays, and are configured to allow removal and replacement of an aerosol spray canister. In some implementations, the spray dispensers include an actuator lock.
