In the beverage maker according to the present invention, the second cover lid (11B) covers the fitting portion of the receptacle body and has a first sealing portion which comes into contact with the rim of the cartridge cover sheet, and a second sealing portion which comes into contact with the inside upper side of the rim of the cover sheet And a universal cap having a sealing portion. FIG. 3 is an exploded perspective view illustrating the universal cap, and FIGS. 4 to 6 are cross-sectional views illustrating respective embodiments of the universal cap.

In Fig. 4, the edge C1a of the cover sheet C1 is divided into dotted lines for convenience.

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 portion T2 serves to prevent the leakage of the extraction solvent in contact with the edge of the cover sheet of the smaller cartridge if the cartridge CR shown is the largest among the cartridges to which the cartridge CR 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, which is in contact with the inside of the cover sheet rim of the used cartridge, functions to some extent as a function of the third sealing portion, that is, the function of preventing exposure of the extraction solvent balance. Thus, the second enclosure and the third enclosure, which are components of a comprehensive and somewhat abstracted concept, are designed to have a single protrusion or recess (without closure (constituting a closed circuit) at the same height (Or preferably have a depth).

The universal cap 53 according to the present invention includes the first cover lid 11A and more particularly the second cover lid 11B forming part of the first cover lid 11A, Lt; / RTI >

Up and down by the opening / closing operation of the cover cover, the perforation pin 53a performs the operation of perforating the cartridge cover sheet,

And an assembly of a cap body (T) having a pressure disk (53A) and a sealing part so that the cap (53) can be lifted and lowered.

More specifically, as can be seen in Fig. 3,

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.

As can be seen from the incision view in the first one-dot chain line on the right side of FIG. 3,

The receptacle 30 has a tight fitting portion 35A around the fitting portion 31A of the main body 31. The universal cap 53 and in particular the cap body T is attached to the fitting portion 31A of the receptacle main body 31 35A in contact with the first sealing portion T4.

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).

4, the stability of the engagement between the cap 53 and the receptacle 30 is further improved by the fact that the support (not shown) of the main body 31 of the receptacle 30, which supports the lower portion of the flange Cb of the cartridge C, Portion 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.

4, the bottom surface of the cap body T, that is, the ceiling Tc (see a perspective view of the first one-dot chain line on the right side in FIG. 3)

The high-temperature and high-pressure extraction solvent is ejected from the nozzles of the circulation means 50, that is, the perforation pins 53a, except for the first to third sealing portions T1, T2 and T3, The cover sheet C1 of the cartridge CR can be brought into close contact with the ceiling Tc more quickly than in the case of filling the inside of the cartridge C.

On the other hand, the cap 53 of the alternative embodiment shown in the upper one-dot chain line of Fig. 4 has the cap body ceiling protruding downward,

This cap body ceiling protruded in a smooth gradient form causes the extraction solvent of high temperature and high pressure to be ejected from the nozzle of the distribution means 50, that is, the punch pin 53a, The cover sheet C1 of the cartridge CR can be brought into close contact with the ceiling Tc faster than the basic shape and the embodiment of Fig.

In the alternative embodiment shown in the upper one-dot chain line in Fig. 4, even if the residual solvent after the extraction solvent or extraction is leaked through the hole of the cover sheet formed by the breakage by the perforation pin 53a

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

This form illustrates an example of a cartridge.

The essential function of the distribution means for such a capsule (or pod) type cartridge is that the upper and lower breaking means 50A, 50B, i.e. the perforation pin 53a and the perforation projection 55a, are carried out.

First, the upper breaking means 50A is basically composed of a perforation pin 53a, and the breaking operation is performed by the upward and downward swings of the cover cover.

7 and 8, the second cover lid 11B of the beverage maker according to the present invention is provided with the universal apparatus including the circulating means and the upper breaking means, as shown in the left first and second dash- And an elevating drum for fixing and mounting the cap.

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 punch pin are connected to each other to supply hot water. Thus, as can be seen in the first one-dot chain line on the right side in Fig. 8, the mounting and dismounting drum 51 is prevented from being damaged A long hole (47A) through which the tube passes is formed on one side of the rear surface of the drum (47), and it is preferable to secure a displacement space of the tube due to the rising and falling of the elevation 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 lifting swing of the cover lid, the lifting drum 51 is pressed by the pressure disk 53A to come into close contact with the flange around the opening of the container body of the cartridge C and is discharged through the piercing pin 53a The cap 53, which constitutes the essence of the sealing means for preventing the hot water from passing through the cartridge only and passing through the gap between the outer surface of the cartridge container main body and the fitting portion 31A of the receptacle 30 without passing through the cartridge, And a hollow h through which the 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.

The following is a brief description of the connection operation of the sealing means and the sealing of the receptacle described above.

The lifting drum 51 is lowered by the lowering of the cover lid and the pressing disk 53A presses the deformable cap 53 so that the cap is contracted, The peripheral edge of the opening portion of the cartridge body C is pressed while the rim of the structure contracts, deforms, or descends (thereby causing the spacing space between the pressing disk and the cap) to seal off the upper surface of the body,

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.

Mesh disks 53B are arranged on the lower surface of the cap 53 as shown in a plan view and a bottom perspective view in the right third and fourth dash-dot line circles in Fig. 8, and the dispersion grooves 53g having a concentric circular structure And a water passage hole 53w is formed in the dispersion groove and a central protrusion 53n having a top surface shape is formed at the bottom center 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 the upper and lower portions of the cartridge smoothly passes through the cartridge and is discharged only to the lower portion, the nozzle communicating hole 20n in the central position of the engaging portion 21 of the storing portion 20, 13, and the cup located in the beverage storing portion 10A.

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 >

When the extraction is completed, the cover cover is opened, the sliding member 23 serving as the advancing / retreating means is pulled open, and the cartridge CR having only the residue left after the extraction from the fitting portion 31A of the exposed receptacle 30 is removed.
