  • the flow of water caused by the increase in pressure during this initial time period T is substantially constant. At a certain point in time there is a substantial increase in the flow rate of the water from the reservoir. This increased flow causes a drop in pressure within the chamber due to the substantial reduction in water volume therein, without a corresponding increase in pressure due to a rise in water temperature.

  • By being able to spray fluid into the cup there is created a foam in the cup. This can be useful for many different kinds of beverages.
  • the unit be of a disposable nature and for single use only, it may be possible to develop the unit for multiple use in microwave oven. In such a form, different bags of essences or components which water or flavoring must be forced can be provided separately. Also, in other cases, the drinking cup can be optional. As such, the consumer may be able to use their own drinking cups in combination with the base reservoir. Although the configuration is shown whereby water is forced upwardly through the device, there could be configurations wherein use of the water is located in the top reservoir and drips 12 into the cup below. In different situations, it may be necessary to provide a temporary seal between the water and dairy containing fluid and the coffee so that premature mixing inadvertently or otherwise does not take place before the unit is placed in the microwave oven. This seal may be manually removable or may break under the pressure of steam generating in the one reservoir and forcing itself into the second reservoir through a coffee bag or the like.

Abstract

L'invention concerne un système de préparation et de cuisson de composants comestibles, dans un four à micro-ondes comprenant différentes cellules ou compartiments (18, 20) contenant différents composants du produit consommable voulu. Sous la pression des micro-ondes sur les composants, la pression d'un des composants rompt les séparations entre les cellules, de sorte que les composants peuvent se mélanger et que le produit fini voulu, qui peut se présenter sous forme liquide ou solide, soit produit. Ledit système jetable permet la fabrication de boissons chaudes, comme l'expresso et le capuccino, dans un four à micro-ondes. Un des ingrédients peut être un produit laitier comme le lait, et l'autre peut être de l'eau.
