I've been using plastic pitchers with lids and plastic beverage storage bottles with lids purchased from a dollar store of which there seem to be a growing number. They work extremely well even for long term (a week or two) storage and they also have spouts for pouring. As mentioned above, they do not have reliable measurement markings so make your own with a Sharpie by pouring in reliably measured quantities of water. As the stock in dollar stores seems to change often, if you see ones you like, don't hesitate to buy them as they may not be there again next week.
