扑满，又名钱筒、储蓄罐、存钱罐、闷葫芦罐，在粤语中称为钱罂，是储存硬币的容器。从前多用竹筒或陶瓷制造，现代则多使用塑胶，人造橡胶或金属等其他材质。传统的扑满除了竹筒采用原型外，其余多制作成猪的造形，其大肚子象征着财富的积累与富足，近年来扑满的造形则比较多样化。

旧时的扑满除了顶端有一个用于投入硬币的狭长小缝外，别无其他出入口，如果真的要用里面的钱，就必须破坏它。这个设计可以教育小孩储蓄的概念：用钱时必须慎重考虑。现在的扑满多在底部开有小洞，并用橡胶封住，以便将钱取出。

在传统的中国家庭，父母总会给孩子一个扑满，以帮助孩子养成存钱和理性消费的习惯。

Piggy bank (sometimes penny bank or money box) is the traditional name of a coin container usually used by children. The piggy bank is known to collectors as a "still bank" as opposed to the "mechanical banks" popular in the early 20th century. These items are also often used by corporations for promotional purposes. The use of the name 'piggy bank' gave rise to its widely-recognized 'pig' shape, and many financial services companies use piggy banks as logos for their savings products.
