A handleless cabinet latch uses a guide pin riding on a heart-shaped cam track to convert one inward push into a lock and the next into a pop; the sliding pin drops into one notch of the track to hold the plunger back, and on the next push, the pin finds the exit ramp, releasing the loaded spring to kick the door open.

Why This Cabinet Door Opens When You Push It ClosedAdded:
This cabinet opens when you push it closed.
The push drives a hidden plunger inward loading a tiny spring behind the door.
A sliding pin is the memory. It drops into one notch of the heart-shaped track holding the plunger back. On the next push the pin finds the exit ramp. The loaded spring kicks the door out. So the next click lets you predict the pop.
