DETAILED DESCRIPTION

[0079] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0080] To facilitate the inflow of hot water and the outflow of coffee liquid, the coffee capsule box in the related art generally adopts a shell structure in which an upper cover and a lower cover are matched, and openings for the inflow and outflow of fluid are fixedly provided in the upper cover and the lower cover respectively, and the upper cover and the lower cover are usually connected by threads. After the capsule is loaded, it is often necessary to twist the upper cover and the lower cover for multiple turns. During this process, the capsule often cannot withstand the shear force caused by the relative rotation of the upper and lower parts, and then the surrounding surfaces are broken, causing coffee powder to overflow. The leaked coffee powder stains the user's clothes and home work environment, and leaves coffee stains on the inner and outer surfaces of the coffee capsule box and the coffee machine.

[0081] In order to solve the above technical problems, as one aspect of the utility model, a coffee capsule box is provided. Figures 1 to 10 As shown, the coffee capsule box includes an upper cover 100, a base 200, an upper bin body 300 and a lower bin body 400, wherein the upper bin body 300 is disposed in the upper cover 100, and the lower bin body 400 is disposed in the base 200, and when the bottom opening of the upper cover 100 is butted with the bottom opening of the base 200, the upper bin body 300 and the lower bin body 400 are buckled together to form a capsule bin for accommodating the capsule 10;

[0082] like Figures 1 to 6As shown, the top of the upper cover 100 has an injection port 110 communicating with the interior of the upper chamber body 300, and the bottom of the base 200 has an outlet 210 for collecting the fluid flowing out of the capsule chamber;

[0083] like Fig. 9 , Fig.10 As shown, the outer side wall of one of the upper cover 100 and the base 200 has a plurality of tenons 610 distributed circumferentially around the corresponding opening, and the inner side wall of the other of the upper cover 100 and the base 200 has a plurality of slots 620, the slots 620 include an avoidance slot 621 and a limiting slot 622, the limiting slot 622 extends along the circumferential direction, the avoidance slot 621 is connected between the limiting slot 622 and the corresponding opening end surface, and the plurality of tenons 610 can respectively pass through the avoidance slots 621 of the plurality of slots 620, and enter the corresponding limiting slots 622 as the upper cover 100 and the base 200 rotate relative to each other, so as to fix the upper cover 100 and the base 200 in connection.

[0084] In the coffee capsule box provided by the utility model, the upper compartment body 300 and the lower compartment body 400 are used to directly contact the capsule 10, and confine the capsule 10 in the capsule compartment formed by the buckling of the upper compartment body 300 and the lower compartment body 400. When brewing coffee, fluid (such as steam, hot water or water vapor) is poured in from the injection port 110 on the top of the upper cover 100, flows through the interior of the capsule 10 and extracts the effective ingredients in the coffee powder to form coffee liquid, and finally the coffee liquid flows out from the outlet 210 at the bottom of the base 200.

[0085] In addition, in the present invention, a plurality of latches 610 are provided on the outer side wall of one of the upper cover 100 and the base 200, and a plurality of slots 620 are provided on the inner side wall of the other.

The upper cover 100 and the base 200 are fixed together by the abutment relationship between the latches 610 and the side walls of the limiting slots 622. Compared with the threaded connection scheme in the prior art, in the present invention, the relative rotation angle of the upper cover 100 and the base 200 when they are twisted can be smaller, thereby preventing the foil around the capsule 10 from breaking due to excessive rotation and preventing coffee powder from escaping, thereby ensuring the cleanliness of the coffee capsule box and the coffee capsule extraction device (such as a coffee machine), reducing the cleaning time cost, and ensuring that the user's clothes and home working environment are clean, thereby improving the user experience.

[0086] As a preferred embodiment of the present invention, Fig.11 As shown, there is a feed angle α between the extension direction of the limiting groove 622 and the bottom end surface of the upper cover 100 (or the top end surface of the base 200).

[0087] In the embodiment of the utility model, there is a feed angle α between the limiting groove 622 and the bottom end surface of the upper cover 100, so that as the upper cover 100 and the base 200 rotate, the tenon 610 drives one of the upper cover 100 and the base 200 closer to the other when entering the limiting groove 622, thereby ensuring the stability of the connection between the two.

The avoidance grooves 621 of the slots 620 are connected between the limiting grooves 622 and the bottom opening of the upper cover 100. The top of the base 200 can enter the bottom opening of the upper cover 100, and the plurality of latches 610 can pass through the avoidance grooves 621 of the plurality of slots 620 one by one, and be inserted into the corresponding limiting grooves 622 as the upper cover 100 and the base 200 rotate relative to each other.

[0091] In other embodiments of the present invention, the tenons 610 may also be formed on the upper cover 100.

[0093] In the embodiment of the utility model, a clamping portion 623 protruding from the bottom of the limiting groove 622 is further formed in the limiting groove 622. When the tenon 610 slides into the limiting groove 622 along the circumferential direction, the clamping portion 623 is also squeezed into the clamping groove 611, thereby fixing the rotation angle between the upper cover 100 and the base 200, and further improving the stability of the coffee capsule box after buckling.
