Difference between Singleton design pattern & Spring Singleton bean scope

What is the difference between Spring Singleton bean scope & Singleton Design pattern? or how are they different ?

Singleton pattern is described at per class loader level.
Singleton bean scope is per spring container. Spring simply creates a new instance of that class and that is available in the container to all class loaders which use that container. 

Suppose you have two scenarios:
1. There are multiple class loaders inside the same spring container..
2. There are multiple containers using same class loader..

In first case - you will get 1 instance while in case 2 - you will get multiple instances ...
