kinetic energy
Let's say you compress the spring. Work (mechanical energy) is required to compress the spring; this energy is stored in the spring and can be recovered (converted to another type of energy) when the spring returns to its normal position.
The energy that is used by you to compress the spring to close the box is stored in the spring until some one opens the box and releases the energy in the spring.
elastic potential energy
Thermal energy is not the energy stored by things that stretch or compress. This type of energy applies to strain potential energy. Thermal energy refers to motion energy due to the random vibration of atoms or molecules within an object.
The potential energy of a spring is defined by this equation: U=.5kx2 U= potential energy (in joules) k= the spring constant x= the displacement of the spring from equilibrium. (the amount that the spring is stretched or compressed) This equation tells us that as a spring is compressed by a distance x, the potential energy increases proportionately to x2

It is produced by converting some other type of energy into potential energy. For example, it takes an effort to lift an object up (against the force of gravitation) or to compress a spring.

That's called elastic energy, and it is a type of potential energy.
