We’ve all seen those videos from the news of a dry Christmas tree going up in flames and the fire hazard that an unwatered Christmas tree is. Every year I struggle with watering our Christmas tree. I have to crawl on the ground underneath the tree, undo the tree skirt, then check if it even needs water and if so how much. Then crawl back out making a mess of pine needles, if it does need water you struggle to pour water into the stand without spilling it everywhere. There has to be a better way to do this, so I turned to a quick patent search in InnovationQ to see what creative ways people have come up with to make this task easier. Here are six patents I found with different ways to solve the problem:

US5349997 System for watering inside trees

Granted: September 27, 1994

Many patents I found were similar to this basic version of a funnel apparatus (11) so that you can water the tree without having to climb underneath. The benefit of this system is that it is a series of tubes (8) that fit together. By being collapsible it’s a small item to store away and have in easy reach when you need to water the tree.

US6082043 Christmas tree watering device

Granted: July 4, 2000

This option with a “Reindeer” head (10) caught my eye right off. In this patent, the filler is left attached to the tree as a decoration, so there is no storage issue. Besides just being a way to fill the tree it includes a notification via a blinking nose (50) or audible “HO HO HO” when the water level in the base has fallen below a predetermined level using a sensor (34) in the base.

US20040124987 Fluid level monitor for tree stands

Published: July 1, 2004

This one is similar to the “reindeer” head above but splits the filler ornament (50) separate from the indicator ornament (20). Where this one stands out is that the buttons on the snowman ornament are a series of lights that give an indication of the water level in the tree stand. This feature lets you judge how much water is needed to fill the stand, not just if the water was below a certain level.

US5157868 Passive Christmas tree waterer and monitor

Granted: October 27, 1992

Here is an alternative to filling using the funnel and at standing height. There were many patents similar to this one where a decorative water reservoir (100) is provided separately from the tree stand base. To fill the tree base you would take the lid off the present and add the water to it. A benefit of this design is the stability of the reservoir being placed on the floor rather than a funnel/object being placed in the tree. For a visual indicator of water level, this patent uses by a buoyant object (104) visible in monitoring column 103. One additional goal of this patent was to not use any electrical current as a safety feature.

US4075614 Christmas tree fire detector and alarm

Granted: February 21, 1978

An alternative way of addressing the issue of dry Christmas trees and the fire danger they create is disclosed in this patent. While not assisting with filling the tree this patent was of interest as it is an ornament (12) with a built-in fire alarm. It is disclosed as being able to be powered by a socket (29) in the tree lights or by a battery. Since a dry Christmas tree burns so quickly the concept is that if the alarm is located at the source of the fire homeowners will be notified much faster and be able to evacuate and alert the fire department.

US20090050339 System and method for extinguishing a fire

Published: February 26, 2009

Besides using one of the watering systems or a fire alarm, here is a patent that discloses a system for putting out the Christmas tree once it has caught fire.  This system uses tree topper (504) and ornaments (510) as a way to quickly disperse flame extinguishing materials like those found in a fire extinguisher. The tubing (512) for the system is disclosed as being made to appear as ribbon or garland on the tree.
