Spraying Device With Inverted Nozzle Shaft For Container Mouth Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray devices for cleaning containers, particularly the mouth area, are inadequate in ensuring thorough cleaning due to the limitations of external cleaning methods, which often fail to effectively reach and clean the opening.
Innovation Solution
A spray device with a combination of internal and external nozzles positioned on a common nozzle shaft, driven by a cam control, where the external nozzles direct spray jets from below to reach the container's mouth and exterior, while internal nozzles spray from below to clean the interior, with the external jets extending beyond the container's length to create effective water currents for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If external nozzles spray from above onto the bottom of the container, then the exterior cleaning is achieved, but the mouth area cannot be satisfactorily cleaned
Solution Approach 1:
The patent inverts the conventional spraying direction by positioning nozzles below the container and spraying upwards. The external nozzles spray from below to clean the exterior surface, while internal nozzles spray through the opening to clean the interior and mouth area. This inverted arrangement allows the spray jets to converge at the mouth area from opposite directions, achieving thorough cleaning without complex nozzle arrangements above the container.
Solution Approach 2:
The patent combines internal and external cleaning functions into a single spraying device located below the container. Both internal nozzles (for interior cleaning) and external nozzles (for exterior cleaning) are positioned together below the container opening, with their spray jets converging at the mouth area. This merging of functions simplifies the overall device structure while achieving comprehensive cleaning of both interior and exterior surfaces.
2Manufacturing precision
If spray jet from external nozzle extends beyond container length to create water currents, then cleaning effectiveness is improved, but spray system complexity increases
Solution Approach 1:
The patent employs a rotatable nozzle shaft that can be rotated by a cam control to dynamically align nozzles with containers of different sizes and positions. The nozzle shaft rotates to bring appropriate nozzles into alignment with the container opening, allowing the spray jet to extend beyond the container length and create effective water currents along the exterior surface. This dynamic adjustment simplifies the spray system compared to having multiple fixed nozzle positions.
Solution Approach 2:
The patent changes the operational parameters of the spray system by using a cam control mechanism that adjusts the rotation angle of the nozzle shaft. This allows the spray jet direction and extension length to be varied according to container dimensions, creating optimal water currents for cleaning the exterior surface while maintaining a relatively simple nozzle structure.

AI summary
The spraying device (1) has a container conveyor for transporting a container (3) with the mouth facing downwards. A spray nozzle (6) acts on the container from the bottom. An external spray nozzle (6a) acts on an outer surface of the container. Another external spray nozzle is directed to the outer surface of the container next to an internal spray nozzle (6i) directed to spray through the mouth of the container. The external and internal spray nozzles are arranged on a common nozzle shaft (8). An independent claim is also included for a method for cleaning containers.
