Candle Core Bubble Prevention via Bottom-Up Wax Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing candle manufacturing processes often result in air bubbles forming within the core's longitudinal orifice due to the filling method, which can lead to an unappealing appearance as bubbles rise during cooling or become apparent as the wax is consumed.
Innovation Solution
The core is designed with a configuration where the filler material is poured from bottom to top, using open channels to fill the core from the base, ensuring air is expelled before the material covers the core, preventing bubble formation by allowing the material to flow around the core and into the orifice from the bottom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the core's longitudinal orifice is filled with molten wax from top to bottom, then the filling process is simple, but air bubbles are trapped inside the core
Solution Approach 1:
The patent inverts the conventional filling direction by introducing molten wax through channels at the base of the core rather than from the top. This reversal allows air to escape naturally during filling while wax fills the orifice from bottom to top, eliminating trapped air bubbles without complicating the manufacturing process
Solution Approach 2:
The core is segmented with multiple channels (at least two) distributed around its base, allowing molten wax to enter through multiple points simultaneously. This segmentation ensures complete filling of the longitudinal orifice while providing multiple escape paths for air bubbles, preventing their entrapment
2Shape
If the core is completely submerged by molten wax, then the core is concealed from view, but air bubbles may remain trapped inside
Solution Approach 1:
By inverting the filling direction to enter through base channels, the patent ensures air bubbles escape during the submersion process rather than being trapped. The wax fills the longitudinal orifice from the bottom up, pushing air outward through the same channels or through the core's upper opening before complete submersion occurs
Solution Approach 2:
The channels are pre-positioned at the base of the core to facilitate air escape before the wax completely fills and submerges the core. This preliminary arrangement of entry points ensures that air is expelled during the filling process itself, preventing bubble entrapment while achieving complete submersion for aesthetic purposes
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
This method effectively prevents air bubbles from forming, resulting in a more aesthetically pleasing and high-quality candle by ensuring the core is filled without trapped air, maintaining a smooth appearance throughout its use.
Implementation Method 1
the core is provided on its upper base with an extension, with the outlet of said longitudinal orifice located on the apex thereof such that under gravity the filler material will slide toward the periphery of the core

AI summary
Method for manufacturing candles that comprises attaching the wick to a stand and threading the same to a core through a longitudinal orifice, where the method is performed by filling said orifice with a filler material from the bottom, forcing out the air from said orifice before covering the upper outlet thereof, for which purpose the core has lower channels that communicate the longitudinal orifice with the cavity present around the core.
