Removable Spray Can Button With Tapered Nozzle and Hose Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray can nozzles and buttons for pressurized aerosol cans are prone to clogging, sputtering, and fail to securely retain accessory hoses, making them complicated and inefficient to use.
Innovation Solution
A removable spray can button with an improved nozzle, integral hose adapter, and stem connector, featuring tapered orifices and lumens to provide a direct pinpoint spray and securely hold accessory hoses, is designed for installation on pressurized aerosol cans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional spray can nozzles are used, then the spray can operates simply, but the nozzle clogs and sputters easily
Solution Approach 1:
The nozzle is divided into multiple functional segments: a button body, a stem connector for can attachment, and a tapered orifice for spray control. This segmentation allows each component to be optimized independently - the tapered orifice prevents clogging while maintaining simple operation
Solution Approach 2:
The orifice is designed with a specific taper angle that creates localized high-velocity spray flow. This local geometric modification prevents material accumulation and clogging at the critical spray outlet while keeping the rest of the nozzle structure simple
2Adaptability or versatility
If traditional spray can nozzles are used, then the device remains simple, but accessory hoses cannot be securely retained
Solution Approach 1:
The hose adapter function is merged into the button body structure itself. The button body includes an integrated adapter portion that receives and secures accessory hoses, combining what would traditionally be separate components into a single integrated unit
Solution Approach 2:
The button body serves multiple functions: it acts as the actuator, contains the hose adapter for accessory attachment, and integrates the orifice for spray delivery. This multi-functionality allows the nozzle to securely retain hoses while maintaining operational simplicity
3Reliability
If complex valve assemblies with external activators are used, then paint flow can be controlled precisely, but the system requires AC power and is unsuitable for aerosol cans
Solution Approach 1:
The complex external activator and armature mechanism is extracted and replaced with a simple internal button mechanism. The button directly actuates the valve through a stem connector, eliminating the need for AC power, external activators, and complex electromagnetic components while maintaining reliable paint flow control
Solution Approach 2:
The button mechanism is self-actuating through direct mechanical linkage. When the button is pressed, it directly opens the valve via the stem connector without requiring external power sources or complex control systems, making it suitable for aerosol can applications
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a targeted, clog-free spray and securely retains accessory hoses, enhancing user experience and operational efficiency compared to traditional spray can nozzles and buttons.
Implementation Method 1
an interior portion comprising a tapered interior lumen and at least one tapered orifice comprising a first upper tapered orifice and a second lower tapered orifice
Implementation Method 2
the lock ring comprises an elastic lock ring clamping part which can move back and forth along the radial direction of the lock ring, and when the elastic lock ring clamping part is not compressed, the elastic lock ring clamping part is flush with the inner peripheral edge of the lock ring or lower than the inner peripheral edge of the lock ring

AI summary
Improved replacement spray can buttons configured for removable installation on pressurized aerosol spray cans, include an integral stem, a hose adapter and an improved integral pin-point spray nozzle. Portions of the button may be injection molded. The improved nozzle provides a direct pin-point spray without the need of a straw, or red hose accessory provided with many spray lubricants. The button includes a tapered orifice and a tapered interior lumen. The button may beneficially be used to securely hold a hose accessory if desired, so it will not fall out during use. The button may accommodate the same size stem or orifice of existing spray cans, and be used as a replacement button for any suitable spray products. The button may be used by manufacturers and consumers to replace the button currently provided with such products, and may be installed in place of the existing button at the same location.
