  • the warm food releases water vapor, which accumulates in the container and in particular on the lid of the container.
  • the water vapor condenses out and drips back to the warm food in droplet form.
  • the warm food is cooled and softened by the condensed water, giving, for example, crispy hot foods, such as fried French fries, a soft mushy consistency.
  • the food is usually covered by a cover.

Abstract

L'invention concerne un couvercle pour plats, en particulier pour plats chauds, comprenant un corps de couvercle destiné à être disposé au-dessus du plat (12, 26a, 26b, 50, 66, 84) et au moins un non tissé (20, 32, 58) pour l'absorption d'une vapeur d'eau (24) émise par le plat (12, 26a, 26b, 50, 66, 84), le corps de couvercle étant disposé au-dessus du plat (12, 26a, 26b, 50, 66, 84) et recouvrant le plat (12, 26a, 26b, 50, 66, 84), le non tissé (20, 32, 58) étant disposé sur le corps de couvercle et le non tissé (20, 32, 58) empêchant le reflux dans la direction du plat (12, 26a, 26b, 50, 66, 84) d'une vapeur d'eau (24) condensée refroidie à l'état liquide. L'invention permet d'obtenir ainsi un couvercle de structure simple, comprenant au moins un non tissé (20, 32, 58), qui empêche que le condensat ne goutte du non tissé (20, 32, 58) sur les plats (12, 26a, 26b, 50, 66, 84) lorsque le non tissé (20, 32, 58) est saturé.
