We are SO impressed that many of you recognized this item easily!
Yes siree, Bob, it is indeed the sprinkler top for a spray starch bottle for perfectly pressed clothing. I (as many of you) remember my mother and grandmother frequently using one of these.
Thankfully, permanent press was invented, but you still can’t beat the look of a crisply pressed white button-down!
Please scroll down to read the comments that were left as guesses in our earlier post. Happy weekend to all!
Also, as any of you commented to us, the sprinkler cap shown above is topping a vintage coke bottle!

Is is just the sprinkler top for water in the bottle. To starch them you would dip them in the sink that had starch. They were separate things.
Agreed. We never used a sprinkler for starch – it only ever held distilled water.
