The number on the Heinz Ketchup bottle
You might have seen this number and guessed that it had something to do with advertising or part of the label of the company. However, it was designed to mark the spot where you should tap in order to get ketchup onto your food.
A spokesperson for Heinz said, “To release ketchup faster from a glass bottle, here is a little secret from Heinz. The sweet spot to tap on the Heinz bottle is the embossed 57 on the neck. All you need to do is apply a firm tap where the bottle narrows and the ketchup will come out easier.”
