[0001] The utility model relates to the technical field of coffee filter cup production, in particular to a coffee filter cup. Background Art

[0002] The coffee filter cup is used to store solid concentrated ingredients and is used in conjunction with extraction equipment to make coffee.

[0003] In the prior art, such as the Chinese authorized utility model patent CN201821304342.2, a disposable capsule filter cup is disclosed, which includes a cup body and a filter layer, wherein the filter layer has a bag mouth portion and a bag body portion, wherein the bag body portion extends from the cup mouth to the cup bottom and is pocket-shaped, and the filter layer is assembled in the inner cavity of the cup body from the water inlet of the cup body in the vertical direction. Due to the special pocket-shaped shape, the following deficiencies exist during assembly: (1) The bottom shape is uncertain, resulting in that several pocket-shaped filter layers to be assembled cannot be stacked in the vertical direction, thereby requiring a larger placement area; (2) It is necessary to cooperate with the expansion mechanism to act on the inner side of the pocket-shaped filter layer so as to facilitate the insertion into the cup body; (3) The filter layer is difficult to manufacture. Utility Model Content
