Problems solved by technology

Therefore, controlling the flow rate is important to the quality of the coffee, as too slow a flow rate will result in over-extraction and the coffee will be bitter, and too fast a flow rate will result in weak extraction and the coffee will lack flavor

Embodiment Construction

[0027] Figure 1a A section of the capsule 1 is shown with the body 2 having a generally frusto-conical form. The upper end 3 of the capsule has a second frusto-conical portion 4 of smaller diameter than the lower end. The upper end 3 is further provided with a further frusto-conical recess 5 at the center of the upper end 3 . The capsule is provided with a flange 7 at the end of the body 2 remote from the upper end 3 .

[0028] To ensure that the capsule functions effectively in the wide variety of capsule coffee machines on the market, the four dimensions marked V, W, X and Y are critical, and if problems with the insertion and ejection of the capsule in the machine are to be avoided, Need to take advantage of these dimensions.

[0029] Figure 1b A further dimension on the capsule is shown, namely A, which is the distance from the sealing surface of the capsule to the surface of the capsule at the top of the capsule that interfaces with the machine blade, Figure 1c Dim...

Abstract

A capsule for use in a coffee machine having a brew chamber, which capsule is formed from a ductile metal such as aluminium. The capsule has a generally frusto-conical form with an upper surface and a lower surface, an annular flange being provided at the lower surface. An annular seal is provided on the annular flange having first and second layers, wherein the first layer comprises long, well-bound fibres of a cellulose material.

Description

technical field [0001] The invention relates to a beverage capsule for an espresso machine, in particular for making espresso under high pressure. Background technique [0002] Electric espresso machines are well known. A traditional espresso machine consists of a water chamber and a heating element adapted to heat the water to around 95-98 degrees Celsius, which is then pumped at high pressure of 15 to 19 bar to the filter holder or pre-filter. Low pressure systems also exist. Filter holders generally comprise a handle portion and a frame portion provided with two or three lugs adapted to engage in a mounted position with a machine brewing head into which water is pumped. The frame portion is adapted to receive a filter, usually a metal bowl with a plurality of perforations through its bottom. In use, the filter is filled with finely ground coffee and water is forced through the coffee at high pressure generated by the pump to produce espresso, which is collected in a cu...
