detailed description

The embodiments of the present application are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are intended to be illustrative, and are not to be construed as limiting.

The embodiment of the present application provides a coffee capsule, as shown in FIG. 1, comprising: an upper cavity 1 and a lower cavity 2, and a filter 3 is disposed between the upper cavity 1 and the lower cavity 2; The upper surface of the upper cavity 1 is covered with a first sealing film 11 and the lower surface is covered with a second sealing film 12; the lower surface of the lower cavity 2 is connected with a bottom case 21 which is recessed inward, and the bottom case 21 The center is provided with a small hole 211, and the outer edge of the bottom case 21 encloses a flat support plane.
