Paint Can Squeegee with Ramp for Annular Recess Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Paint cans with removable and resealable lids often experience a less than airtight seal due to paint residue in the annular recess, leading to dryout and unusable paint, as well as potential mixing with usable paint when the dried paint is removed.
Innovation Solution
A squeegee apparatus designed to attach to paint cans, featuring channels for the can lips, a projection into the annular recess, and a ramp that directs paint or debris upwards and into the can, ensuring a clean seal and preventing paint loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If paint is poured into a painting tray by tipping the paint can, then paint can be transferred to the tray, but paint flows into and fills the annular recess causing seal failure and paint dryout
Solution Approach 1:
The squeegee apparatus is used before sealing the paint can to remove paint from the annular recess. By performing this cleaning action beforehand, the recess is cleared to receive the sealing rim, ensuring an airtight seal while maintaining the convenient tip-pour operation.
Solution Approach 2:
The squeegee apparatus extracts paint from the annular recess by scraping it off the surface. The channels receive the lips while the projection scrapes paint off the recess surface, separating the paint removal function from the pouring operation.
2Reliability
If paint resides in the annular recess, then the seal becomes less than airtight, but removing the lid causes dried paint to crack and fall into the paint can
Solution Approach 1:
The squeegee apparatus performs preliminary cleaning of the annular recess before the paint dries. By removing paint immediately after pouring and before sealing, the system prevents both seal failure and the subsequent problem of dried paint cracking and contaminating the usable paint.
Solution Approach 2:
The ramp structure redirects paint that would otherwise remain trapped in the recess (causing harm) and guides it back into the can interior (converting it to a beneficial action). This ensures paint is recovered rather than lost or dried in the recess.
3Reliability
If a projection extends into the annular recess to remove paint, then paint can be cleared from the recess, but the structure becomes more complex
Solution Approach 1:
The squeegee apparatus combines multiple functions in a single device: the channels receive and position the can lips, the projection scrapes paint from the recess, and the ramp redirects paint back into the can. This multi-functionality reduces the need for separate tools while maintaining simplicity.
Solution Approach 2:
The squeegee apparatus is designed to nest onto the existing can structure, with channels receiving the lips and the projection extending into the existing annular recess. This nesting approach allows the device to integrate with the can's geometry rather than adding independent complex structures.

AI summary
Various embodiments are described for a squeegee apparatus configured to facilitate a removal of paint or other debris in an annular recess of a can, such as a paint can. The squeegee apparatus may include a body having a first recess to receive a first lip of a can, a second recess to receive a second lip of the can, and a projection to extend into an annular recess of the can. The squeegee apparatus may include a guard wall projecting laterally from the body and a ramp at least partially defined by a distal end of the projection. The ramp and the projection can be positioned such that, when the body of the squeegee apparatus is pulled along the annular recess of the paint can, paint or other debris residing in the annular recess is forced up the ramp and redirected towards an interior chamber of the can.
