Paint Can Accessory Spout and Wiper for Lid Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paint can accessories fail to prevent paint from drying in the lid indentation, leading to stuck lids, rust, and contamination, while also causing paint to drip and obscure label information, and hinder stacking and handling of paint cans.
Innovation Solution
A paint can accessory with a spout and wiper rod that allows the original lid to be used for sealing, preventing paint from entering the lid indentation, and features a design that allows secure stacking and easy handling of paint cans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If paint is poured from the can, then paint can be transferred to another container, but paint enters the lid indentation causing it to dry and stick the lid
Solution Approach 1:
The patent extracts the harmful element (paint) from the critical area (lid indentation) by introducing a spout that directs paint flow away from the indentation, preventing paint from entering and causing sticking
Solution Approach 2:
The spout acts as an intermediary device between the paint can interior and the pouring destination, controlling the paint flow path to bypass the lid indentation area entirely
2Productivity
If paint is poured from the can, then paint can be transferred, but paint drips down the outside of the can causing mess and obscuring labels
Solution Approach 1:
The spout extracts and redirects the paint flow away from the can exterior surfaces, channeling it through a controlled path that prevents drips from reaching the outside of the can and obscuring labels
3Ease of operation
If the lid is removed to pour paint, then paint can be accessed, but the can must be resealed which requires tools and time
Solution Approach 1:
The spout is pre-installed on the can, allowing paint to be poured directly through it without removing the lid, eliminating the need for repeated opening and resealing operations
Solution Approach 2:
The spout enables continuous painting operation by allowing the can to remain sealed throughout the pouring process, maintaining the useful action of having paint accessible without interruption while preserving the sealed state
4Reliability
If a replacement lid or accessory is used to prevent paint from entering the indentation, then lid sticking is prevented, but the original lid with label information is lost
Solution Approach 1:
The invention segments the lid system into two functional parts: the original lid retained for its information-bearing and sealing functions, and a separate spout added for the pouring function, allowing both to coexist without interfering with each other
5Ease of operation
If paint is wiped from the brush against the inside of the can, then excess paint is removed, but paint is squeezed into the lid indentation
Solution Approach 1:
The spout serves as an intermediary surface for wiping the brush, providing a dedicated area for paint removal that is spatially separated from the lid indentation, preventing paint from being squeezed into the sealing area

AI summary
Apparatus is provided for an accessory for a paint can. The apparatus presented comprises a roughly cylindrical frame disposed for being securely seated on a paint can and which may securely receive the original lid of the paint can. The apparatus further comprises, in selected aspects, a sealable spout for pouring paint; an air vent to allow smooth pouring; a rod for wiping paint from a brush; sealants on surfaces to provide a good seal between the accessory and the lid and/or the accessory and the paint can, and concavities to allow the handle to be used.
