What is the significance of sealing the regularly used china cabinets during Passover?

My mother worked for a Hasidic rabbi and Rabitz when I was in high school, and who shared their memories of important holidays and traditions that accompanied holidays. He mentioned that during Passover, cabinets, where regular plates had to be kept closed - special dishes (one for meat, one for dairy products) is used instead - but could not remember the traditional meaning of closure cabinets.
I understand how to seal the windows prevents the use of plates inside them, but what I'm looking for is cultural or religious meaning of the act of closing cabinets.If there is no cultural or religious significance, and it really is just a physical, visual reminder not to use the dishes, that's fine too.

There is no special religious significance. We sealed up, because it is easy to forget when you are reaching a plaque in the middle of the night or early morning, waiting, we have to use Easter dishes.

Additionally, for those people who sell their chametz (foods containing yeast or grains forbidden), which prevents them from going to the deck to be held on items that are no longer "legally" theirs.
