a cup-like clear plastic vessel having a flat bottom-wall with a round hole in its centre into which is inserted a downward facing food safe silicon umbrella valve plus 2 ¨
expression vent holes covered by the umbrella valve; a side-wall extending vertically from the bottom-wall with threads for a lid; a plastic inverted-U shaped lid with an air-tight food safe silicon gasket around its interior edge and shaped to press air-tight against the lip of the vessel with threads to allow the lid to be screwed tightly onto the vessel, and with a round hole in the center of the lid into which is inserted an upward facing food safe umbrella valve with a pressure release handle plus 1 or more pressure release vent holes covered by the umbrella valve; and a plastic and nylon mesh filter basket with a small flange on its bottom exterior to be inserted into the vessel and sit on the bottom-wall to create a shallow cavity above the bottom-wall umbrella valve and below the basket, and a larger cavity above the basket, into which are put ground coffee and water. A
flange extends from the exterior bottom-wall of the vessel with a lesser diameter than the vessel to enable the coffee-maker to sit securely in a cup or mug.
[0009] In order to make coffee, the coffee-maker sits on and slightly into a typical coffee cup or mug. A nylon mesh filter-basket, ground coffee and a cup of water are put into the filter-basket and the lid is screwed on tight to create an air-tight seal between the lid and the vessel. Both umbrella valves also make the vessel air-tight. As result, no water can escape from the vessel prior to the opening of the lower umbrella valve.
[0010] Next the coffee-maker and cup are put into a microwave oven. The device and contents are heated in the microwave oven at the high setting for the length of time the microwave oven requires to boil a cup of water (approximately two to two and a half minutes) plus 5-10 seconds. When the water in the vessel boils, the steam created generates the pressure required to open the lower umbrella valve and the hot coffee infusion (freshly brewed coffee) is rapidly expressed through the expression vent holes.
The nylon mesh prevents contamination of the coffee infusion with coffee grinds. If the lower umbrella valve fails to open, the upper umbrella valve opens to relieve the steam pressure in the vessel while the screwed on lid is designed to resist the pressure.
[0011] After the coffee has been made and the device removed from the microwave oven and begins to cool, the interior of the coffee-maker contains a partial vacuum and the upper umbrella valve has a small handle to enable it to be opened manually to allow air to enter the coffee-maker to equalize the pressure in order to easily remove the lid. It should be noted the device does not require metal or bi-metal parts, melting parts or essentially moving parts such as are typical with other patented or patent applied for microwave coffee-makers.
[0012] In one non-limiting aspect of the present invention, there is provided a clear plastic microwave coffee-maker that includes a round container vessel (1) having a bottom-wall with a downward facing exterior flange (11), a side-wall that extends upwardly from the bottom-wall to form a container cavity with threads around the lip (9); a nylon mesh filter basket (5) with a flange (13); and a screw on lid (2) with a gasket (12) and threads on the interior side wall (10). The bottom-wall includes a food safe umbrella valve (4) plus 2-4 expression vent holes (8) covered by the umbrella valve to enable a hot coffee infusion to be expressed from the container cavity. The lid is designed to create an air-tight seal with a food safe gasket around the interior diameter and has a food safe umbrella valve (3) with a pressure release handle (14) plus 1 or more pressure release vent holes (7) covered by the umbrella valve to allow for pressure release if the lower umbrella valve fails to open. The umbrella valves have concave flexible flaps (16) that become convex under sufficient steam pressure to allow venting. The nylon mesh filter basket is immersed in water and contains ground coffee. The nylon mesh (6) is sufficiently fine to prevent ground coffee granules from expressing out of the vessel expression vent holes and contaminating the freshly brewed coffee. There are one or more grooves (15) on the outside bottom of the coffee-maker to allow air to easily vent from the cup being filled with coffee. The vessel is made of clear plastic to visually monitor boiling and venting.
[0013] In another and/or alternative aspect of the present invention, the coffee-maker could be made of coloured plastic, ceramic pottery, glass or similar non-metallic material.
Said aspect would require a method to maintain the airtight seal other than threads such as making the lid heavy enough to resist the steam pressure generated in the coffee-maker or clamps to hold the lid tight against the lip. Visual monitoring might not be possible.
[0014] In another aspect of the invention the umbrella valves are made of food safe rubber or similar material in place of silicon.
[0015] In another aspect of the invention the lower umbrella valve could be a duckbill or similar pressure operated one-way valve.
[0016] In another aspect of the invention the lid is made entirely of food-safe rubber or silicon or similar material with an umbrella release valve that would release at a higher pressure than the bottom valve and designed to wrap around a lid similar to the lid on some travel mugs. The vessel would require an exterior facing lip for the lid to wrap around. Said lid would be ideal for a ceramic vessel.
