In describing the universal cap 53 and the cartridge extraction beverage maker M, in particular, the universal beverage maker according to the present invention, for the sake of convenience, the approximate direction of the rigidity is shown in FIGS. 1, 6, 9 and FIG. Specific reference to 10,

The upper, lower, right, and left sides are divided in the state as shown in the drawing, and the direction is specified in accordance with the reference in the description related to the other drawings.

First, the universal cap 53, which is one of the cores of the present invention, which can be used in the beverage maker for extracting cartridges according to the present invention, is shown in Figs.

Regardless of the cartridge (CR) (see FIG. 1), the size and shape of each manufacturer may be used in a universal beverage maker (M) for extracting cartridges having a plurality of receptacles 30 to accommodate and use all of them. have.

Components of the rotating body 20, the rotating means R, and the other beverage makers having the same or different coupling parts 21 to accommodate the same or different cartridges will be described later with reference to FIG.

The universal cap 53 covers the receptacle 30 in which the cartridge CR is accommodated, and an extraction solvent, especially high temperature and high pressure water, passes through the cartridge to extract the extraction object (mainly coffee powder), and extraction. With the basic function of preventing the situation of the discharge of unauthorized matter without

Even if heterogeneous cartridges of different shapes and sizes are introduced, even if one cap is used universally for all of these heterogeneous cartridges, the sealing property is guaranteed to prevent the extraction solvent from being discharged without extraction. For this purpose, the universal cap 53 is provided with a plurality of seals.

The depicted cartridge CR is in the form of a capsule (or pod), which, if desired, can also be applied in the form of a pack type cartridge packaged in a porous casing, such as a nonwoven fabric.

In the structure of the illustrated capsule (or pod) type cartridge CR, the lower mesh disk 57 is first embedded in the container-shaped body C and then the extraction target body, that is, the coffee powder P, The upper mesh disk 53B is covered with the upper mesh disk 53B and the opening Ca of the body C is covered with the cover film C1 in the vacuum packaging state as much as possible and attached to the upper flange Cb of the body C to be.

The mesh disk 53B has a plurality of dispersion grooves, in particular, dispersion grooves 53g having a unique concentric circular shape and a radial structure overlapping each other.

Hydrothermal passage holes 53w are formed along this dispersion groove, and a central projection 53n having an upper and lower narrow shape is formed at the center of the lower surface of the mesh disk 53B (three right sides of FIG. 10). From the bottom observation perspective in the second (from top) single-dot chain line).

10 and 1, the central projection 53n is the extraction solvent distribution means 50, in particular, the nozzle having the tip in the form of a needle, that is, the upper destruction means 50A having the core 53A as a core. ,

The breakage of the cartridge cover sheet C1 by the perforation pin 53A and the high temperature and high pressure solvent supplied from the pump after the puncture,

Due to the central projection 53n (see Fig. 10) having an upper and lower narrowing shape in the upper mesh disk 53B,

Despite the thinness of the mesh disk

Radially spread and move in the groove portion 53r (see FIGS. 1 and 2) formed in the center at the top,

Is spread widely by the dispersing grooves 53g and the hot water passage holes 53w to meet with the extraction object, that is, the coffee powder P, and starts extraction.

Next, the high-temperature, high-pressure water that has smoothly passed through the inside of the body C of the cartridge CR is extracted,

Only the extracted liquid is discharged by the lower mesh disk 57, and the residue remains on the lower mesh disk 57.

In addition, the lower mesh disk 57 has an upward protrusion 57n at its upper portion. Since the upward protrusion has its unique cross-over shape, the hot water passing through the cartridge and performing the extraction function is changed into a drink And can be discharged downward through the holes of the mesh disk 57 while spreading over the upward protrusion.

The illustrated capsule type cartridge includes a body having an opening Ca and a flange Cb and a cover sheet C1 which is coupled to the flange of the body in a state where the extraction target body P is embedded in the body, .

The basic configuration of these cartridges, however, is the same for packed cartridges packaged in a porous envelope in the abstracted concept.

That is, the porous 'lower shell' can be classified as 'body' and the 'upper shell' can be classified as 'cover sheet'

The upper and lower outer shells having the extraction object embedded therein can be separated regardless of the manufacturing method and the assembling order, and the separated lower outer shell has the " opening ", and the upper and lower outer shells, Quot; and " flange ", respectively.

In addition, packed cartridges packed in porous shells should also be prevented from discharging the waste water without extracting solvent, ie, high-temperature, high-pressure water, without passing through the cartridge. For this purpose, a method of sealing the upper and lower shells from the flange .

Accordingly, the universal cap of the present invention and the universal drink maker using the universal cap have a concept that can be universally applied irrespective of the type of the cartridge.

Next, the receptacle 30 includes a main body 31 having a fitting portion 31A for accommodating the cartridge CR.

Essentially, the shape and size of the fitting portion are deformed in accordance with the cartridge CR. In the present invention, a plurality of receptacles 30 are introduced to implement the universal beverage maker M, and the fitting portions of the main body are heterogeneous or homogeneous.

The pod type cartridge CR is required to be punched in the bottom surface of the cover sheet C1 and the body C,

The extraction solvent circulation means comprises an upper breaker means 50A essentially comprising a perforation pin 53a,

And a lower breaking means 50B constituted by a perforated disk 55 having a perforation projection 55a as its essence.

However, the destruction and puncturing of the cartridge is not essential, so it is referred to as an extraction solvent 'distribution means'.

The bottom surface (C) of the illustrated pod type cartridge (CR)

Upon mounting the receptacle main body fitting portion 31A of the cartridge,

Or upon completion of locking by the lever L of FIG.

Or the supply of water for extraction at high temperature and high pressure through the perforation pin 53a, the bottom surface of the cartridge body C is deformed by water pressure

The punching and breaking may be performed by contacting the punching protrusion 55a of the punching disk 55.

A foam disk 59 is arranged below the punch disk 55.

The foam disk is preferably made of a silicon material or other safety material resistant to heat and low risk of environmental hormone exposure,

1 and 2 after the extraction beverage discharged through the extraction beverage passing portion 55b inclined to the center of the perforated disk 55 is spread out to the outside of the foam disk 59 along the radially arranged guide path (59b),

(Crema, which covers espresso shots with a dense golden brown foam) that enhances the coffee, especially the espress specific flavor, by increasing the residence time through the through holes 59a at the end of each guide path .

In addition, as can be seen from a perspective view in the lower right one-dot chain line circle in FIG. 1, the receptacle 30, the bottom surface 37 of the main body 31 is provided.

A radial passage 37a corresponding to the guide passage 59b of the bubble disk 59 is formed and these passages are connected to the central discharge hole 37c,

A plurality of radial spaced apart pillars 37b protrude around the central discharge hole 37c,

The center engaging projection 59c of the foam disk 59 in the discharge hole 37c of the bottom of the receptacle body 37 (it is possible to maintain an easy assembling process and stable coupling state in the shape of a light beam) (second point of FIG. 1 right) See the bottom perspective view in the dashed circle)

Spaced column 37b is stably coupled to the annular groove (see FIG. 2) around the lower center engaging projection 59c of the foam disk 59,

The extracted beverage is discharged from each discharge hole 37c of the bubble disk 59 through the radial passage 37a and the central discharge hole 37c without clogging

Finally, abundant crema is formed and falls through the nozzle communication hole 20n at the center position of the coupling part 21 and the nozzle 13 of the housing to the cup located in the beverage container 10A.

Through the passage portion 55b of the bubble disk 59 and then through the bubble disk 59 guide path 59b → through hole 59a → through hole 59a → the main body 31 of the receptacle 30, The zigzag extract liquid flow path passing through the communication path 37a of the bottom portion 37 → the discharge hole 37c and the separation column 37b and the bubble disc 59 of the bottom portion 37 of the receptacle 30 main body 31, The lower central engaging projection 59c and the like can reduce the discharge pressure of the extracted liquid after being extracted at a high pressure to improve safety and convenience of use.

1 and 2, the universal cap 53, particularly the cap body T, which is one of the cores of the present invention, covers the fitting portion 31A of the main body 31 of the receptacle 30, and the cartridge CR The first sealing part T1 is in contact with the edge C1a of the cover sheet C1 and the second sealing part T2 is in contact with the inner top surface of the edge c1a of the cover sheet C1.

In FIG. 1, the edge C1a of the cover sheet C1 is divided by a dotted line to indicate an area.

The first sealing portion T1 is supplied to the space between the cap 53 and the cover sheet C1 of the cartridge so that the solvent for extracting through the cartridge CR leaks out of the area of the cartridge CR, And thus,

The second sealing part T2 serves to prevent leakage of the extraction solvent by coming into close contact with the edge of the cover sheet of the smaller cartridge if the cartridge CR shown is the largest cartridge that can be employed.

A plurality of protrusions constituting the second sealing portion T2 may be provided,

The first and second hermetically sealed portions T1 and T2 may have various shapes such as a circular shape, a square shape and a triangle shape in conformity with the rim shape of the cartridge CR to be employed. Basically, It is preferable to have the same height without disconnecting (constituting a closed circuit).

Next, the beverage maker of the present invention further includes a circulation means (50) including a nozzle for supplying an extraction solvent into the inside of the cartridge (CR)

Furthermore, it is preferable that the universal cap 53, particularly the cap body T, further includes a third sealing portion T3 surrounding the nozzle and contacting the upper surface of the cover sheet C1.

The third sealing portion T3 is accommodated in the main body 31 of the receptacle 30 and is sealed by the universal cap 53 so that the extraction solvent, particularly, the high-temperature and high-pressure water, As a result,

Essentially, the extraction residue is exposed through the extraction hole of the cartridge cover sheet (C1) when the cartridge (CR) is removed after the extraction is completed, so that the user may be exposed to the hand of the drink maker, It serves to prevent the occurrence of pollution-causing situations.

The third sealing portion T3 is arranged adjacent to the nozzle, particularly, the perforation pin 53a of the upper breaking means 50A in the figure, so that the extraction solvent surrounds the nozzle (perforation pin) So that it is prevented from leaking to the top.

The third sealing portion is formed to fit the shape of the edge of the nozzle, but it is preferable that the third sealing portion is circular, and it is preferable that the third sealing portion has the same height without disconnection (constituting a closed circuit) so as to be uniformly adhered to the upper surface of each cartridge cover sheet edge.

On the other hand, the second sealing portion (T2) in contact with the inner side of the cover sheet of the used cartridge also performs a function of the third sealing portion, that is, to prevent the exposure of the extraction solvent balance to some extent. Therefore, the second sealing part and the third sealing part, which are components of a comprehensive and some degree of abstraction, are the same height when they are actually implemented (materialized) and have one projection or groove (without disconnection (which constitutes a closed circuit)). (Or preferably have a depth).

On the other hand, the universal cap 53 according to the present invention is raised and lowered by the locking member 40 associated with the lever (L) as described later, the punching pin 53a performs a cartridge cover sheet drilling operation,

In addition, the cap 53 is composed of an assembly of a pressurizing disk 53A coupled to the lifting drum 51 and a cap body T having a sealing part to enable the lifting and lowering of the cap 53.

More specifically, as can be seen in FIGS. 1 and 10,

The pressing disk 53A is fitted into each of the screw holes 51b of the corresponding elevating drum 51 through the screw projections 53p so that the bolts are inserted into the three screw projections to ensure firm fixing,

In addition, before the pressurizing disc 53A is coupled to the elevating drum, the perforation pin 53a is constrained to the center mount hole 53h by the engagement protrusion 53a ', and the watertightness is detected by the O- 53b.

In addition, as can be seen in the perspective view of the incision in the first one-dot chain line circle of Figure 1,

The body T of the cap 53 has an inward coupling groove Ta in which the pressing disc 53A is received and coupled to each other and the coupling groove Ta of the soft flexible cap body T for ensuring the hermeticity, On the bottom of

An annular recessed portion Tb is formed

The edge of the hard pressurizing disc 53A for facilitating the pressurizing force transmission and the hermeticity can be easily assembled.

As can be seen in FIGS. 1, 2 and 3, the receptacle 30 has a close contact 35A around the fitting portion 31A of the main body 31, and the universal cap 53, in particular a cap. The body T further preferably includes a fourth sealing portion T4 in contact with the contact portion 35A of the receptacle body 31.

The fourth sealing portion T4 prevents the extraction solvent of high temperature and high pressure (for example, 15 bar) from leaking out and spraying from the outside in the state where the cap 53 and the receptacle 30 are in tight contact with each other, And is intended to improve the stability of the closed state and the stability in order to reliably prevent it.

The tight fitting portion 35A is in the form of a projection formed without being cut along the fitting portion 31A of the receptacle body 31,

The fourth sealing portion T4 is formed as a recessed groove formed along the rim of the lower surface of the cap body T so as to be engaged with each other (When the outer sole making up the outer surface of the contact portion 35A and the fourth sealing portion T4 focuses on the skirt).

Further, in FIG. 3, the stability of the coupling state of the cap 53 and the receptacle 30 is also supported by the main body 31 of the receptacle 30 supporting the lower portion of the flange Cb of the cartridge CR body C. It is improved by the part 35B. This is because the sealing force can not be sufficiently ensured only by pressing the first sealing portion T1 of the cap body T on the upper surface of the thin cartridge body C.

On the other hand, the cap body (T) is the bottom surface, that is, the ceiling (Tc) (see the perspective view incision in the first one-dot chain line circle of Figure 1) as can be confirmed in more detail in Figure 2,

Except for the first to third sealed portions T1 (T2) and T3, the plate has a flat plate shape, and the extraction solvent having a high temperature and high pressure is ejected from the nozzle of the distribution means 50, that is, the drilling pin 53a. When the inside of the cartridge C is filled (faster than the embodiment of FIG. 3), the cover sheet C1 of the cartridge CR may be in close contact with the ceiling Tc.

In contrast, the cap 53 of the alternative embodiment shown in the upper one-dot chain line of FIG. 2 has a cap body ceiling protruding downwards,

Due to the smoothly projecting cap body ceiling, the high temperature and high pressure extraction solvent is ejected from the nozzle of the distribution means 50, that is, the drilling pin 53a, to fill the inside of the cartridge C (Fig. 2). The cover sheet C1 of the cartridge CR may be in close contact with the ceiling Tc more quickly than the basic form and the embodiment of FIG. 3.

In addition, in the alternative embodiment shown in the upper one-dot chain line of FIG. 2, even if the extraction solvent or the remaining liquid after the extraction is leaked upward through the hole of the cover sheet formed by the destruction by the punching pin 53a,

Due to the protruded ceiling, the cover sheet is deformed into a tilted shape toward the center

Upon separation of the cap 53 before or after completion of the cap extraction, the extraction solvent or the extracted filtrate enters the center hole which flows through the inclined surface of the cartridge cover sheet C1 by its own weight.

On the other hand, the cap 53 shown in FIG. 3 has a cap body T ceiling Tc alternatively formed in an arch shape, so that the extraction solvent having a high temperature and high pressure is applied to the nozzle of the distribution means 50. As it is ejected from the punch pin 53a and fills the inside of the cartridge C,

When the lower surface of the body C is inflated and descended to be destroyed by the perforation protrusions 55a of the perforation disc 55,

As the extraction solvent fills the space S (see Fig. 3) between the upper mesh disk 53B and the cover sheet C1, the cover sheet is first raised to allow the space S to be enlarged so that the extraction solvent is sufficient. While staying, it is dispersed and spread widely, so that it can instantly and evenly penetrate the whole extraction object (i.e., the whole coffee P),

The cover sheet C1 is brought into close contact with the second and third sealing portions T2 and T3 by the upward and downward expansion of the cover sheet C1 to firmly achieve the functions of the respective sealing portions, The space between the ceilings Tc is removed so that the residual liquid after the extraction solvent or extraction is leaked to the upper portion through the hole of the cover sheet formed by the breakage by the puncturing pin 53a is prevented from the occurrence of the third The function of the sealing portion is assisted.

In FIGS. 3 and 4, the cover sheet C1 is actually perfectly in contact with the ceiling Tc of the cap body T, but is illustrated in an uneven form for checking the deformation state of the cover sheet for convenience.

In addition, the cartilage body C is shown in a state where the lower surface thereof is expanded and lowered and broken by the perforation disk perforation projection 55a,

Furthermore, the extraction object is omitted for convenience.

The variant shown in FIG. 4 is adjacent to the second and third closure parts T2 and T3 and further to the first sealing part T1, in particular, each sealing part T1 as compared to the embodiment shown in FIG. 3. Inside the (T2) and (T3), auxiliary recesses T1a, T2b, and T3b of separate recessed shapes are provided.

The grooves of the auxiliary sealing portions T1a, T2b, and T3b are preferably continuous and have a uniform depth without interruption in consideration of improvement in airtightness and ease of manufacture.

If necessary, the auxiliary sealing portion may be provided outside the main sealing portion, alternatively formed inside or outside the sealing portion, or may be deformed to be spaced apart from the main sealing portion,

In view of the essential function of the first sealing portion, that is, the pressing function of the cover sheet edge (C1a), it is preferable that the auxiliary sealing portion is formed only inside the main second and third sealing portions.

In addition, as shown in FIG. 4, the degree of deformation during expansion of the cover sheet C1 is more fully in close contact with the sealing parts T1, T2, T3, and the auxiliary sealing parts T1a, T2b, and T3b. It is deformed in the form, and also shown as there is a slightly open gap in Figure 4 is easy to check the shape of each of the main and secondary sealing portion (T1) (T2) (T3) (T1a) (T2b) (T3b). It is only one.

Therefore, the universal use and sealing performance using the universal cap 53 of the present invention can be further improved.

On the other hand, as shown in Figures 6 to 10, the universal beverage maker (M) for extracting cartridges according to the present invention that can use the universal cap is largely equipped with a housing 10, a cartridge ( A receptacle 30 for CR (see FIG. 1), a rotating body 30 having a plurality of engaging portions 21 to which the plurality of receptacles are respectively coupled, and a rotating means R for the rotating body. .

The housing 10 has a shape in which the beverage accommodating part 10 is opened forward as if the animal has an open mouth as shown in the front-oriented perspective view of FIG. 19 is provided, and a detachable grill 19a is provided above the storage space of the remaining liquid tray 19.

 Therefore, the coffee maker according to the present invention is formed by the first shaft of the second link of the locking member 40 coupled to the shaft guide 47b provided on the mounting drum and along the displacement path formed on the mounting drum of the housing. The displacement jaw of the lifting drum is configured to move up and down, and the lifting drum and the angular link are not separated from the mounting drum during the lifting operation.

When the lever L is lowered, the lever L and the links 41, 43 and 45 are diversified in force acting points, and according to the Camlock principle, the pressure of the hot water for extraction in the receptacle 30 is reduced. L) and the loosening and rocking of the linking member are prevented.

As can be seen in the left first and second single-dot dashed circles of FIGS. 10 and 10,

The elevating drum 51 has a bending type nozzle 51A through which a water tank, a boiler and a pipe (not shown) connected to the pump are passed. The nozzle and the drilling pin are connected to each other so that hot water is supplied, so that the tubular body is not damaged even after repeated movement of the lifting drum 51 as can be seen in the first one-dot chain line circle of FIG. 10. The rear side of the drum 47 is formed with a long hole (47A) through which the tubular body passes, it is preferable to ensure the displacement space of the tubular body in accordance with the lifting and lowering of the lifting drum.

A pressurizing disc 53A is fitted to each of the threaded holes 51b of the corresponding elevating drum 51 through a screw projection 53p so that the bolt is inserted into the three screw projections to secure a firm fixation do.

In addition, before the pressurizing disc 53A is coupled to the elevating drum, the perforation pin 53a is constrained to the center mount hole 53h by the engagement protrusion 53a ', and the watertightness is detected by the O- 53b.

Next, when the lifting drum 51 is lowered by the lowering of the lever L, the lifting drum 51 is pushed down by the pressing disk 53A to be in close contact with the flange around the container body opening of the cartridge C and discharged through the punching pin 53a. Cap 53, which constitutes the essence of the sealing means to prevent the hot water passing through only the inside of the cartridge and through the gap between the cartridge container outer surface and the receptacle 30 fitting portion 31A without passing through the cartridge, is formed at the center. The hollow h through which the punch pin 53a penetrates is formed.

The universal cap further includes a coupling member (53C) that prevents the cap body and the pressure disk from being separated from each other.

The engaging member 53C is formed so as to surround the outer circumferential surface of the engaging portion of the cap body and the pressing disc so that the pressing disc is not separated from the cap body.

It is also preferable that the engaging member is provided with a guide portion in the form of a knob coupled in the vertical direction.

Although not shown in FIG. 10, the guide part guides the lifting and lowering of the assembly of the universal cap including the lifting drum by the locking member along the guide path formed inside the cover 11A shown in FIGS. 6 to 9. Have,

Further, when the beverage maker is cleaned, it has a function as a handle for separating the assembly of the elevating drum 51, the pressure disk 53A and the cap 53 after the cover is removed.

The elevating drum 51 further includes an elastic jaw 51d protruding from the upper surface of the lifting drum 51, and further includes an elastic spring 51e engaged with the jaw.

The elastic spring 51e coupled with the supporting jaw 51 has a function of assisting the ascending and descending of the assembly after the lowering movement of the assembly including the universal cap by the pressing of the lever (ie, after the beverage extraction is completed).

Referring to the coupling operation of the locking member, the sealing means, the locking member described above as follows.

When the lifting drum 51 interlocks and descends by the lowering of the lever L, and the pressing disk 53A is deformable, the cap is contracted, in particular, in contact with the pressing disk 53A. While the edge of the upwardly projecting structure (which causes the space between the pressurizing disk and the cap) is contracted, deformed, and lowered, the upper edge of the body is closed by pressing the edge around the opening of the cartridge (CR) body (C),

The lower flange of the elevating drum 51 is engaged with the hinge around the fitting portion 31A of the receptacle body 31 to prevent secondary sealing and leakage of high-pressure hot water to ensure safety.

As the cap 53 contracts and the space between the pressing disk 53A and the cap disappears, the lower end (tip end) of the perforation pin 53a protruding from the lower surface of the pressing disk passes through the hollow h of the cap The film cover C1 of the cartridge CR is pierced.

The lower end of the perforation pin 53a then meets the center of the mesh disk 53B in the cartridge body, and does not descend anymore.

As shown in a plan view and a bottom perspective view side by side in the right third and fourth one-dot dashed circles of FIGS. 10 and 10, mesh discs 53B are arranged on the lower surface of the cap 53 so that the grooves have a unique concentric circular structure. 53g), a hydrothermal passage hole 53w is formed in this dispersion groove, and a central projection 53n in the shape of a light beam is formed at the center of the lower surface of the mesh disk 53B.

Subsequently, when high-temperature, high-pressure water is supplied by the pump, the hot water poured from the end hole of the perforation pin (53a)

Is spread widely by the dispersion grooves 53g of the mesh disk 53B and the hot water passage hole 53w to meet with the extraction object, that is, the coffee powder P, and starts extraction.

The upper protrusion 53n of the upper surface of the mesh disk 53B serves to form a recess in the center of the upper surface of the mesh disk 53 in spite of the thin thickness of the mesh disk, The end portion is accommodated and the high-pressure hot water impinges against the wall surface of the recessed portion to spread widely to ensure even extraction.

On the other hand, the hot water supplied through the hollow h of the body T of the cap 53 through the perforation pin 53a is maintained in watertightness due to the sealing structure of the sealing cap 53 and the pressure disk 53A,

In addition, an O-ring 53b is provided in the upper mounting hole 53h of the pressure disk 53A to ensure airtightness.

The hot water filling the inside of the cartridge body by the completely sealed state pressurizes the bottom surface of the cartridge body C which can be deformed to a predetermined degree,

As a result, the lower surface of the body C is exposed to the perforation protrusion 55a of the perforated disk 55.

The high-temperature, high-pressure water which smoothly passes through the inside of the cartridge CR is extracted,

Only the extracted liquid of the lower mesh disk 57 is discharged, and the debris is allowed to stay thereon. If necessary, the lower mesh disk may further include a filter as required.

The lower mesh disk 57 also has an upward protrusion 57n on its upper side, which has a unique cross-shaped upper (lower) shape, And spread out through the upward protrusions to be discharged through the holes of the mesh disk 57 downward.

A bubble disk 59 is arranged below the perforated disk 55 and is preferably made of silicone or other safe material which is strong against heat and low risk of exposure to environmental hormones,

The extracted beverage discharged through the extract beverage passing portion 55b centered on the perforating disk 55 is spread out to the outside of the bubble disk 59 along the radially arranged guide path 59b, 59a) and increases the residence time to increase the coffee, especially the foam or crema (which covers espresso shots with a dense golden brown foam) that improves the flavor peculiar to the espress.

As described above, since the high temperature and high pressure water supplied after drilling the upper and lower sides of the cartridge smoothly passes through the cartridge and is discharged only to the lower portion, the nozzle communication hole 20n at the center position of the coupling part 21 of the rotating body 20 and the nozzle of the housing ( 13) can be contained in the cup located in the beverage receiving portion (10A) through.

Depending on the need (or depending on the type and structure of the cartridge), the upper destructive means or the lower destructive means or both may be omitted,

For example, the bottom breaking means may be provided so as to be broken by the pressure of the extraction solvent filled in the cartridge body simply by the upper breaking means,

For example, the cartridge body has not only an upper opening but also a lower opening, which is a film member (synthetic resin film or metal (aluminum or its alloy)) foil which can be destroyed by the pressure of the extraction solvent supplied by the pump )). ≪ / RTI >

After extraction, the lever L is opened and the sliding member 23 which is the retraction means is opened and opened, and only the residue left after extraction is removed from the fitting portion 31A of the exposed receptacle 30.

Alternatively, the rotation means R can be turned to immediately extract the cartridge provided in the other receptacle 30.

Thereafter, if necessary, the receptacle 30 may be completely disadvantageous at the coupling portion 21 of the rotating body 20 to perform washing.
