I used to have one of these, but it broke and I cant find a replacement or similar item anywhere.  It was a plastic screw-on dispenser/spout that screws onto a Chlorox bottle.  It replaces the normal bottle cap and remains tightly sealed on the bleach container until empty.  The top has a 1/2 turn twist-to-open action and an extended, no-drip spout for dispensing the bleach without spilling or splashing a drop.  This item is reusable and could be sold as a bleach accessory item in grocery stores.

It is such a great idea and no one makes it anymore, at that I can find.  If anyone knows where to get one of these, please let me know.  Otherwise, it would be a great item for Chlorox to market.
