Party Pump

Great name!

From the website:

Party Pump™

Make a batch for a bunch in this unbreakable jar — carefree entertaining with this self-serve dispenser that holds more than two gallons, so there's no need for constant replenishing.

While this big dispenser comes with a mix and recipes for margaritas, it’s perfect for any summer thirst-quencher.

Serve lemonade, sangria, fruit juice or punch to a crowd — guests can serve themselves.

A flat bottom lets you place it on a table, or put it in a cooler full of ice.

Holds almost 2½ gallons (37 8-ounce drinks).

Plastic — won’t break if knocked to the ground.

....................

That last feature's key.

$19.95 (Flautist, yours comes pre-filled with margaritas — everyone else, you're on your own).
