In the present invention, after the beverage capsule 2 is fixed in the brewing device 1, the membrane tearing mechanism 14 can push the capsule flanging of the beverage capsule 2 along the axial direction of the beverage capsule 2, so that the membrane tearing mechanism 14 can form the tearing opening 25 at the cup edge of the beverage capsule 2 by the axial pushing force applied on the capsule flanging, thus, compared with the traditional brewing device 1 that the beverage capsule 2 is pierced by the bottom piercing pin fixed in the brewing device 1 to form the beverage capsule outlet for the beverage to flow out, in the present technical solution, the tearing opening 25 for the beverage to flow out is creatively formed on the beverage capsule 2 by the membrane tearing mechanism 14 in the manner of tearing, because the membrane tearing mechanism 14 only applies the axial pushing force on the capsule flanging of the beverage capsule 2, and does not directly contact with the beverage, i.e. the beverage does not adhere to the membrane tearing mechanism 14, so that the membrane tearing mechanism 14 tears the beverage capsule 2 in the next process of tearing the beverage capsule 2, the next brewed beverage is not polluted, so that the user can safely and sanitarily enjoy the brewed beverage, and the use experience of the user can be greatly improved. In addition, in the conventional brewing device 1, the beverage remained on the bottom prickling needles is easy to emit unpleasant odor, so in the technical scheme, the tearing opening 25 for allowing the beverage to flow out is formed at the top of the beverage capsule 2 in a tearing and tearing mode, and unpleasant odor such as musty odor, rancid odor and the like which is emitted by the brewing device 1 and the beverage machine and is unpleasant for users can be avoided. Wherein, the beverage capsule 2 can be fixed in the brewing device 1 through the capsule fixing mechanism, and the beverage capsule 2 can also be axially pressed against the beverage capsule 2 on the capsule pressing plate 12 through the capsule pressing mechanism 13 so as to fix the beverage capsule 2 in the brewing device 1, and the like.

In addition, the brewing device 1 further comprises a capsule pressing plate 12 and a capsule pressing mechanism 13, the capsule pressing plate 12 is fixedly connected to the capsule support 11 and is provided with a liquid supply puncture needle 121 for puncturing the beverage capsule 2, the capsule pressing mechanism 13 can move between an initial position and a pressing position, and the capsule pressing mechanism 13 can axially press the beverage capsule 2 on the capsule pressing plate 12 at the pressing position.

The invention also provides a beverage capsule 2, referring to fig. 1 and 11, the beverage capsule 2 comprises an inner cup 21, an outer cup 22 and a sealing film 23, wherein the top edge of the inner cup 21 is provided with an inner cup flanging 211, the inner cup flanging 211 is attached to the top edge of the peripheral wall of the outer cup 22 to form a ring surface seal, the inner cup flanging 211 is provided with an extension portion 2111 extending to the radial outer side of the outer cup 22, and the sealing film 23 seals the top end opening of the inner cup 21.

In addition, the present invention also provides a beverage machine comprising a capsule holder 11 adapted to hold a beverage capsule 2 and a tear mechanism 14, the tear mechanism 14 being capable of partially separating the inner cup flange 211 from the peripheral wall rim of the outer cup 22 to form a tear 25. The beverage machine is a capsule type beverage machine, such as a capsule coffee machine, a capsule soymilk machine or other capsule type beverage machines capable of brewing the beverage capsules 2, which is not illustrated herein.

In the present invention, after the beverage capsule 2 is fixed in the beverage machine, the film tearing mechanism 14 can push the extension portion 2111 of the beverage capsule 2 (i.e. the capsule flanging of the beverage capsule 2) from the bottom to the top of the beverage capsule 2 along the axial direction of the beverage capsule 2, so that the bottom surface of the inner cup flanging 211 and the peripheral wall top edge of the outer cup 22 can be at least partially separated, i.e. the inner cup flanging 211 of the inner cup 21 is torn away from the peripheral wall top edge of the outer cup 22, and a tearing opening 25 for the beverage to flow out from the beverage capsule 2 is formed at the cup edge of the beverage capsule 2. Compared with the traditional mode that the beverage capsule 2 is punctured by the bottom puncture needle fixedly arranged in the beverage machine to form a capsule beverage outlet for beverage to flow out, the beverage capsule 2 can be torn by the film tearing mechanism 14 to form the tearing opening 25 between the outer flange 211 of the inner cup and the top edge of the peripheral wall of the outer cup 22 in the technical scheme, and the part (namely the film tearing mechanism 14) forming the tearing opening 25 can not be directly contacted with the beverage, so that the beverage flowing out of the beverage capsule 2 can not be polluted by the film tearing mechanism 14, and a user can enjoy the brewed beverage safely and sanitarily, and better use experience is provided for the user. In addition, because the drink can not remain on dyestripping mechanism 14, be favorable to avoiding dyestripping mechanism 14 to give out the unpleasant peculiar smell of making the user such as musty or rancid owing to the drink that remains, also can improve user's use and experience. The beverage capsule 2 may be fixed in the brewing device 1 through the capsule holder 11, and the beverage capsule 2 may also be axially pressed against the capsule pressing plate 12 through the capsule pressing mechanism 13 to fix the beverage capsule 2 in the brewing device 1, and the like, without being limited thereto.

Preferably, referring to fig. 11 to 13, the extending portion 2111 includes a bent portion 2111A located at the outer periphery, and the bent portion 2111A extends obliquely toward the cup bottom direction relative to the plane where the top edge of the peripheral wall of the outer cup 22 is located, so that, compared to the structure where the outer edge portions extend laterally and outwardly, the outer periphery of the extending portion 2111 is configured to extend obliquely toward the cup bottom direction relative to the plane where the top edge of the peripheral wall of the outer cup 22 is located, so that the tearing mechanism 14 can tear the inner cup flanging 211 more easily by pushing the bent portion 2111A axially. The bent portion 2111A may extend downward and outward, may also extend downward and inward, and may also extend downward along the axial direction of the beverage capsule 2. In addition, the inner cup flange 211 is configured to extend laterally outward and then extend downward to form a bent portion 2111A, so that the sealing film 23 is connected to the inner cup flange 211 extending laterally outward by thermocompression bonding or ultrasonic welding.

To avoid the situation where the mould for producing the inner cup 21 is inverted, the bent portion 2111A should preferably be arranged to extend radially outwards or axially of the beverage capsule 2, see fig. 11 and 13. Specifically, when the beverage capsule 2 is placed transversely (i.e., the axis of the beverage capsule 2 is changed from the vertical state to the transverse state), the beverage flowing downward from the tear opening 25 has a tendency to splash outward along the axial direction, and thus, the bent portion 2111A is set to extend outward along the radial direction or extend outward along the axial direction of the beverage capsule 2, so that the function of a baffle is achieved, that is, the beverage can be prevented from splashing outward along the axial direction, which is beneficial to preventing other components of the beverage machine from being polluted by the beverage. Further, in order to facilitate the tearing of the inner cup outward flange 211 by the film tearing mechanism 14 and to make the beverage capsule 2 more beautiful, the horizontal included angle of the bending portion 2111A should be not less than 120 ° and not more than 150 °.

Specifically, a pushing groove for pushing the extending portion 2111 is formed in the film tearing mechanism 14, the pushing groove is formed with an axial pushing surface 1412A and a radial stopping surface 1412B which are connected, referring to fig. 1, 2 and 8, and for facilitating the tearing of the inner cup flanging 211 by the film tearing mechanism 14, the axial pushing surface 1412A of the film tearing mechanism 14 should be set to be capable of just touching the extending portion 2111 of the inner cup flanging 211 or just not touching the extending portion 2111. Therefore, the axial projection of the extension portion 2111 on the plane where the top edge of the peripheral wall of the outer cup 22 is located is set to have a radial width of 2mm to 5mm, which not only can prevent the extension portion 2111 from slipping out of the pushing recess, but also can make the pushing recess have a sufficient depth to tear the inner cup flange 211. Preferably, the radial width of the extension 2111 projected in the axial direction of the plane in which the top of the peripheral wall of the outer cup 22 lies is not less than 2mm and not more than 3 mm.

In order to facilitate the separation of the inner cup flange 211 from the peripheral wall top edge of the outer cup 22 by the tear film mechanism 14, referring to fig. 1 and 11, preferably, the outer cup 22 is provided with an outer cup flange 221 or an outer cup flange, and the bottom surface of the inner cup flange 211 is connected to the top surface of the outer cup flange 221 or the outer cup flange by thermocompression bonding or ultrasonic welding, but not limited thereto. The inner cup flanging 211 and the outer cup flanging 221 or the outer cup inner flanging are connected to form a ring surface sealing structure, so that outside air cannot enter the beverage capsule 2 through a gap between the inner cup flanging 211 and the outer cup flanging 221 or the outer cup inner flanging, and the beverage capsule 2 can be kept fresh.

Specifically, the peripheral wall of the inner cup 21 is located radially inside the peripheral wall of the outer cup 22, the inner cup 21 is provided with an inner cup cavity for containing a beverage consumable (such as coffee, milk tea or tea leaves), the top end opening of the inner cup cavity (i.e., the top end opening of the inner cup 21) is sealed with the sealing film 23, the peripheral wall and/or the bottom wall of the inner cup 21 is provided with the inner cup filtering hole 212, and an overflowing cavity communicating the tearing opening 25 with the inner cup filtering hole 212 is formed between the cup wall of the inner cup 21 and the cup wall of the outer cup 22, so that after the liquid supply puncturing needle 121 of the beverage machine punctures the sealing film 23, the beverage can be brewed in the inner cup cavity, and then the beverage formed can sequentially flow through the inner cup filtering hole 212, the overflowing cavity and the tearing opening 25 and flow out from the beverage capsule 2.

In order to make the inner cup 21 suitable for containing not only the extraction type small particle beverage consuming agent, but also the dissolution type large particle beverage consuming agent, i.e. neither the extraction type beverage consuming agent nor the dissolution type beverage consuming agent, will not leak into the flow passage cavity through the inner cup filtering holes 212, referring to fig. 11 to 13, preferably, the inner cup filtering holes 212 are provided on the peripheral wall and/or the bottom wall of the inner cup 21, and the aperture of the inner cup filtering holes 212 should be not less than 0.2mm and not more than 1.5 mm.

In addition, in order to adapt the beverage capsule 2 to a K-CUP type capsule beverage machine, with reference to FIG. 2, an axial gap of 5mm-20mm should be formed between the bottom wall of the inner CUP 21 and the bottom wall of the outer CUP 22 to prevent the bottom wall of the inner CUP 21 from being pierced by the bottom wall piercing needles that pierce the bottom wall of the outer CUP 22. In particular, the K-CUP type capsule beverage machine is provided with a bottom wall piercing needle for piercing the bottom wall of the beverage capsule 2 to form a liquid outlet, in addition to the liquid feed piercing needle 121 for piercing the sealing membrane 23 of the beverage capsule 2.

Optionally, referring to fig. 2, 11 and 14, the top of the inner cavity of the inner cup 21 is provided with an upper splitter plate 24, and the upper splitter plate 24 is formed with a plurality of upper overflowing holes 241, so that, by adding the upper splitter plate 24, an even splitting effect is achieved, especially for the extraction type beverage capsule 2, liquid can uniformly and slowly flow into the beverage consumable through the plurality of upper overflowing holes 241 arranged on the upper splitter plate 24, a better even extraction effect can be achieved, and the brewed beverage has a more savoury and mellow beverage taste. In order to prevent the extraction type small particle beverage consuming agent and the dissolution type large particle beverage consuming agent from leaking through the upper overflowing hole 241, the pore size of the upper overflowing hole 241 should preferably be not less than 0.2mm and not more than 1.5 mm. Specifically, if the aperture of the upper overflowing hole 241 is set too large, it is not beneficial for the liquid to uniformly flow to the beverage consumable through the upper overflowing hole 241, and therefore, in order to make the upper overflowing hole 241 have a better uniform flow dividing effect, the aperture of the upper filtering hole should be set to be not larger than 1.0 mm. Of course, the upper splitter 24 may not be provided in the dissolving-type beverage capsule 2 in order to provide a good brewing and dissolving effect for the dissolving-type beverage consumable, but is not limited thereto.

Preferably, the central portion of the upper splitter 24 is formed with a central depression 242 depressed toward the cup bottom, as shown in fig. 11, 14 and 15, so that the liquid sprayed from the lancet 121 can be prevented from directly flowing into the beverage consumable through the upper overflowing hole 241 by the blockage of the central depression 242, and the beverage consumable can be sufficiently extracted, thereby making the extracted beverage more savoury and mellow. In order to keep the central depression 242 clear of most types of commercially available lancets 121 (i.e. most types of lancets 121 do not collide with the central depression 242 after piercing into the beverage capsule 2), the depression depth of the central depression 242 should be 2mm to 10mm and/or the port diameter of the central depression 242 should be 1mm to 5 mm. Further, the port diameter of the central depression 242 is not less than 2mm and not more than 4 mm.

Optionally, tear mechanism 14 is configured to: in the process that the capsule pressing mechanism 13 moves from the initial position to the pressing position, the capsule pressing mechanism 13 is driven to move along the axial direction of the beverage capsule 2 so as to push the outward flanging of the beverage capsule 2, and then the tearing opening 25 is formed on the beverage capsule 2. Of course, there are also a number of suitable arrangements of the film tearing mechanism 14 to move relative to the stationary beverage capsule 2 and to axially push the capsule flange, for example, the film tearing mechanism 14 is arranged to: in the process of the capsule pressing mechanism 13 moving from the initial position to the pressing position, the capsule pressing mechanism 13 is triggered to move along the axial direction of the beverage capsule 2 to push the capsule flanging and the like of the beverage capsule 2, but not limited thereto. The capsule pressing mechanism 13 drives the film tearing mechanism 14 to move axially along the beverage capsule 2, that is, in the process that the capsule pressing mechanism 13 moves from the initial position to the pressing position, the capsule pressing mechanism 13 pushes the film tearing mechanism 14 to move axially along the beverage capsule 2, and the capsule pressing mechanism 13 triggers the film tearing mechanism 14 to move axially along the beverage capsule 2, that is, in the process that the capsule pressing mechanism 13 moves from the initial position to the pressing position, the capsule pressing mechanism 13 triggers the film tearing mechanism 14 to move axially along the beverage capsule 2 by touching the film tearing mechanism 14 or touching a switch button, for example, by triggering the capsule pressing mechanism 13, the film tearing mechanism 14 can eject axially along the beverage capsule 2, and further, the capsule flanging is pushed axially to form a tearing opening 25 and the like. In this technical solution, it is preferable that the capsule pressing mechanism 13 drives the film tearing mechanism 14 to move along the axial direction of the beverage capsule 2, so that compared with the capsule pressing mechanism 13 triggering the film tearing mechanism 14 to move along the axial direction of the beverage capsule 2, the capsule pressing mechanism 13 drives the film tearing mechanism 14 to move, which has higher operation reliability, and the structure of the brewing device 1 is simpler. Wherein, in the process that the membrane tearing mechanism 14 axially pushes the capsule flanging, the beverage capsule 2 is fixed in the capsule bracket 11.

Preferably, referring to fig. 1, the film tearing mechanism 14 includes a return spring 142 and a sliding frame 141 slidably mounted on the capsule holder 11, the return spring 142 is disposed along the axial direction of the beverage capsule 2, and two ends of the return spring 142 are respectively connected to the capsule holder 11 and the sliding frame 141, the sliding frame 141 can be driven by the capsule pressing mechanism 13 to overcome the return force of the return spring 142 and move along the axial direction of the beverage capsule 2 to push the capsule flanging of the beverage capsule 2, so that the sliding frame 141 can be driven to overcome the return force of the return spring 142 and move along the axial direction of the beverage capsule 2 in the process that the capsule pressing mechanism 13 moves towards the capsule pressure plate 12, and further the sliding frame 141 can axially push the capsule flanging to form the tear opening 25 on the beverage capsule 2. Further, the carriage 141 can be reset by the return spring 142 during the movement of the capsule pressing mechanism 13 from the pressing position to the initial position.

Further, the through sliding grooves 111 extending in the axial direction of the beverage capsule 2 are symmetrically formed on the side wall of the capsule holder 11, the sliding rack 141 is provided with the sliding shafts 1411 extending into the through sliding grooves 111 and the pushing arms 1412 located at the bottom of the capsule holder 11 and connected between the sliding shafts 1411, the capsule pressing mechanism 13 pushes the sliding shafts 1411 to enable the pushing arms 1412 to apply pushing force on the outward flanging of the beverage capsule 2, and referring to fig. 1, 5 and 6, the sliding rack 141 can be pushed by the capsule pressing mechanism 13 more stably, the sliding rack 141 can be enabled to push the outward flanging of the beverage capsule 2 smoothly, the operation reliability of tearing and tearing the beverage capsule 2 by the sliding rack 141 can be improved, and the success rate of tearing and tearing the beverage capsule 2 to form the tear opening 25 by the sliding rack 141 can be improved. Of course, the structure of the sliding frame 141 and the corresponding capsule holder 11 may be various, for example, sliding grooves extending in the axial direction of the beverage capsule 2 are symmetrically formed on the inner side wall of the capsule holder 11, the sliding frame 141 has sliding shafts 1411 extending into the sliding grooves, and pushing arms 1412 located at the bottom of the capsule holder 11 and connected between the sliding shafts 1411, etc., but not limited thereto.

Specifically, referring to fig. 1 and 8, the pushing arm 1412 is formed with a pushing groove for pushing the outward flanging of the capsule, and the pushing groove is formed with an axial pushing surface 1412A and a radial stopping surface 1412B which are connected, so that during the movement of the capsule pressing mechanism 13 driving the sliding rack 141, the outward flanging of the beverage capsule 2 firstly falls into the pushing groove, and then the outward flanging of the capsule is given with axial pushing force by the axial pushing surface 1412A, and the outward flanging of the capsule is prevented from continuously sliding outwards along the radial stopping surface 1412B by the radial stopping surface 1412B, so that the outward flanging 211 of the inner cup 21 is separated from the top edge of the peripheral wall of the outer cup 22 to form the tearing opening 25.
