Vending of drinks.

The present invention relates to a drinks vending machine composed of accommodation that incorporates a chamber formed with an opening through which you can inserting a beverage container into the chamber, said container provided with minus a portion of deformable wall and an outlet with which a beverage supply line can be connected to a faucet device; a lid to close the opening of the camera; a means of blocking and sealing to close the chamber tightly so that a pressurized space is formed between the deformable wall portion of the beverage container and a wall inside the chamber, and a means of pressurization to pressurize pressurized space so that the drink is forced out of the container by the exit.

This vending machine is disclosed in the WO-A-95/20540, in order to serve carbonated or non-carbonated drinks, namely beer. In this device, already known, a flexible bag containing a Drink is installed in a chamber of a container, after which the chamber is sealed tightly by a cover. The space between the chamber and the bag is pressurized. A flexible hose connect a bag outlet with a tap supplied drinks. To this end, the hose goes through an opening in the lid. A disadvantage of said construction is that the hose in said opening must be sealed very effectively because the hose is located at least partially in the pressurized space.

Another beverage vendor according to the preamble of claim 1 is known by the US-A-5251787.

It is an object of the invention to improve the vending machine of the type defined in the first paragraph, of so that the above-mentioned disadvantage is avoided and also, to make the device easier to use.

To this end, the beverage vending machine will characterized by the fact that the means of blocking and sealing it is arranged between the beverage container and the chamber, so that it according to the pressurized space between an interior wall of the chamber and at least the deformable wall portion of the container, the exit of the container being located outside the space pressurized

Now the pressurized space is no longer delimited by the lid. In the present invention the line or hose coupled to the outlet is located completely outside the pressurized space. There is no longer the problem of tightness of the mode indicated above in relation to the device according with WO-A-95/20540. Another advantage additional is that, due to the position of the blocking means and tightness, it is now possible to automatically and easily create a pressurized space when the beverage container is inserted into the housing chamber. The device is easier to handle for the user.

A preferred embodiment of the apparatus is characterized in that the locking means consists of locking wedges equipped with springs, which collaborate with a flange of the container for close the container in the chamber. When a beverage container is inserted in the chamber, the outer wall of the container pushes the wedges of backward lock, against the effort of the spring, until a container flange exceeds the locking wedges, after which the locking wedges return to their previous position to secure the container.

An embodiment that includes a variant of the blocking means indicated above is characterized in that a flange of the chamber opening has a piece annul in which the locking wedges are mounted so that they can move elastically in radial directions.

A preferred embodiment is characterized in that the device includes an annular collar mounted on a neck with the container outlet opening. Said collar is provided with a flange to collaborate with the locking wedges to hold the container in the  camera. Said collar can be joined in solidarity with the container Or it can be built as an independent removable piece. The middle sealing consists of sealing rings between the wall inside the chamber and an outer neck flange and, in the case from being an independent removable neck, a sealing ring additional between the neck of the container and an inner flange of the collar.

The apparatus also comprises a mechanism of Unlock to open the container. More details of the same in the description of an embodiment in relation to the Figures.

A further embodiment of the apparatus is characterized in that the pressurization means includes a pump that it can be activated and deactivated by a switch that can be act on the lid. The device also has a valve pressurization space safety, which can be operated through the lid. When the lid is closed the valve is closed safety and the pump is started. When the lid is opened it Turn off the pump and the space safety valve opens pressurized, after which the beverage container can be removed from the camera, once unlocked said container.

For reasons of hygiene, the mouth of a new container full of beverage is sealed by a membrane of perforable tightness. To pierce said membrane the container incorporates a drilling mechanism connected with a hose beverage supply, which automatically pierces the diaphragm of tightness as soon as the pressurized space is pressurized by first time. To this end, the apparatus is characterized in that, when a drink container is disposed and locked in the chamber, a determined distance between the container flange and the wedges of blocking, which allows the upward movement of the container to the pressurize the pressurized space, thereby drilling the membrane.

A construction through which you can pierce a sealing membrane is disclosed in the WO-A-95/20540. However, in said Construction drilling must be done manually.

In another preferred embodiment, the device faucet consists of two parts, of which a lower part is connected in solidarity with the housing and a part upper is articulated in relation to the lower part, being partially formed the beverage supply line by a flexible hose that can be hooked between the top and the bottom one This upper part has a crank of drive and said lower part has a closing mechanism which, together with the drive crank, can open or clamp the drink supply hose. In this way get a mechanism, simple operation for the user, to install the beverage supply hose to the point where that the drink has to be dosed. After coupling the hose of drinking supply with the bottom, the top is joins the bottom, hooking the hose in position to the time it clamps. When the drive crank is opened, the hose is no longer pinched and the drink comes out of the hose through the effect of pressure in the pressurized space.

The apparatus also has a series of elements of safety to prevent unwanted activation of pressure and unwanted discharge of the drink.

Due to the constructive measures employed, the operation of the device is very easy as well as safe for the user.

We will now describe the invention of more detailed form, by way of example, in relation to a Embodiment illustrated in the drawings. In these drawings:

The beverage vending machine illustrated in Figure 1 consists of a housing 1 with an opening 2 that provides access to a chamber 3. A cover 4 is articulated with the 1 housing to open and close the camera. Through the opening 2 a beverage container can be installed in chamber 3, for example A container of beer. The accommodation also incorporates a faucet device 6. A beverage supply line 7 has one end connected to an outlet 8 of the beverage container and the other end with the faucet device 6.

Figure 2 is a schematic representation of the beverage vending machine in which a container of drink 5. An annular piece 9, mounted on the upper flange of the housing 1 around opening 2, incorporates a means of blocking and sealing of the beverage container 5. The blocking means used to hold the beverage container in chamber 3 consists of a plurality of locking wedges with movable springs 10 in radial direction The beverage container has a collar 11, joined by articulated shape with a container wall and equipped with a flange 12 to collaborate with locking wedges 10. A sealing ring 13 is attached to the annular piece 9 to close the container in the camera tightly. When a beverage container is installed in the chamber, the container flange forces the locking wedges 10 to stand out against the effort of the springs 14. Once that the flange exceeds the wedges, they move inwards radial shape due to the pressure of the springs, closing the container in the camera like this. At that time the sealing ring 13 it is adjacent to the inner wall 15 of the chamber and next to the container flange 12 (see also Figure 3). Through this board a tight space 17 is formed between the inner wall 15 of the chamber and outer wall 16 of the container. Said space 17 is connected to a pump 19 through a conduit 18. Through the pump can increase the pressure in space 17. The means of Pressure is preferably air. The increase in pressure in said pressurized space means that external pressure is exerted on the deformable wall 16 of the beverage container and, consequently, in the drink. When a tap of the tap device 6 is opened, the drink is forced out through the supply hose of Drink and can be picked up in a glass or cup.

The sealing and blocking process (as well as the unlocking) will be described in more detail below, in relationship with the detailed drawings of Figures 3 and 4. The piece annular 9 with the locking mechanism and the gasket is mounted on the upper flange 20 of the housing 1. This annular piece 9 consists of a lower ring 9a, and, separated therefrom, an upper ring 9b, among which are locking wedges 10. For this purpose, the lower ring 9a incorporates pivots 21, which engage in openings 22 of the locking wedges (Fig. 4). The locking wedges are they press inwards by the effort of a coil spring 14. The inner ends of the locking wedges are shaped like "nose", such that both an upper surface 23 and a lower surface 24 thereof inclines downwards in radial direction inwards. During container installation in the chamber, the oblique upper surface 23 collaborates in separating the wedges 10 by means of the flange 12 of the collar 11 of the container 5. The Bevel 37 of the flange also contributes to this effect. The hoop of tightness 13 engages between a part of the upper flange 20 of housing and lower ring 9a. The sealing ring has a flexible lip 25 that is directed inwards and which also has a downward tilt. The flexible sealing lip forms a tight seal together with flange 12 of the disposed container in the camera. Pressurized space 17 can be pressurized by pump 19. Air is preferably used for said function. The air pressure ensures that the sealing lip 25 is pressed firmly against the flange and ensures a even more efficient sealing of pressurized space 17. The pressure in the pressurized space exerts an effort on the container, which therefore tends to move up. The locking wedges 10 prevent the container 5 from rising upwards.

When you have to remove an empty container from the chamber, first the pressure in the space has to be discharged pressurized and then the locking wedges 10 can be forced back against the effort of spring 14, that is to say they push or stretch out. To this end, a unlocking mechanism formed by an unlocking ring 26 with oblique cam surfaces 27. The ring 26 can be rotated on the axis 28. Each of the locking wedges 10 has been provided with a unlocking pivot 26. Such unlocking pivots collaborate with the oblique surfaces 27 of the release ring 26. To rotate the unlocking ring said ring has a small crank 30, which protrudes through an opening 31 in the upper ring 9b (the upper ring 9b is not shown in Figure 4.). The upper ring also has a small crank 32. Approaching the two cranks 30 and 32, the unlock ring 26 rotates in the direction anti-schedule This means that the surfaces of oblique cam 27 force the unlocking pivots 29, and in consequence to the release wedges 10, to move towards outside, so that flange 12 is no longer blocked and can be remove the empty container 5. It is not possible to remove a container from the chamber when pressurized space 17 remains under pressure. While the space 17 is pressurized, the flange 12 is pressed against the inclined lower surfaces 24 of the wedges 10. The inclined lower surfaces 24 make it virtually impossible to push the wedges 10 back.

Instead of a collar 11 joined together in solidarity with the wall of the container, it is possible to use a "collar removable independent ", as illustrated in Figure 5. After placing a container 5 in the chamber 3 of the apparatus, it is placed a collar 11 'on the neck 88 together with the outlet opening 8 of the container. An outer flange 12 'has a seal annular 13 'to seal it against the inner wall 15 of the chamber 3,  while a 12 '' inner flange has a gasket ring 13 '' to seal it against the neck 88 of the container. So analogous to the example in Figure 3, the flange 12 'collaborates with the locking wedges 10 to lock the container in the chamber of the apparatus.

For hygiene reasons, the beverage container is left tightly closed until used. To this end it is arranged a sealing membrane 33 over the outlet opening 8 and is secure it to the edge of the opening (see Figure 6). The beverage supply line 7 consists of a hose 34 with a perpendicular inlet tube 35 at its inlet end. Saying inlet tube extends to penetrate a joint 36 of the collar at a point just above the membrane 33. When the container 5 is the bottom surface 37 of the flange 12 is placed in the chamber 3 rests on a portion of the flange 38 of the inner wall 15 of the camera. The upper surface of the flange 12 is located at a distance A below the locking wedge 10. When the cover 4 is closed, the upper end 39 of the perpendicular inlet tube is arranged just below the closed lid 4. After start the pump 19, air is pumped into the pressurized space 17 and the pressure gradually increases, causing container 5 to move slowly up until flange 12 is adjacent to the locking wedge 10. During said upward movement the tip 40 of the inlet tube 35 perforates the membrane 33, forcing this mode to the drink to leave the container to the hose towards the faucet device 6.

The tap device 6 is appreciated detailed in Figures 7-10, in which we appreciate that it consists of a lower part 41, joined together solidarity with housing 1, and an upper part 42, articulated with the bottom part through a hinge 43 (Figures 8 and 10). Both parts have a slot 44 and 45, respectively (Fig. 10), in which the beverage supply hose 34 can be arranged. The outlet end of the hose has an outlet tube perpendicular 46. The bottom of the faucet device It has a vertical channel 47 through which the outlet pipe can pass.  For hygiene reasons, the end portion 46a of the outlet tube it is completely projected from channel 47, so that there cannot be contact between the beverage and the bottom 41 of the device faucet To facilitate operation, the outlet tube 46 It has a crank 48, which can incorporate an indication of the type of drink The faucet device also has a mechanism closure by means of which the hose can be clamped or opened flexible. Said closing mechanism consists of a holding block. 48, vertically movable against the force of a spring 50. The clamping block has two vertical pressure pivots 51, which includes a hose clamp 52, formed by a V-shaped pressure element. The hose 34 extends over said V-shaped pressure element. closing mechanism also consists of a lever 53, which is located at the top 42 of the faucet device, pivoting on a pivot 54. On one side of the pivot said lever has an arm bracketing 55 whose ends 56 collaborate with the pivots of pressure 51 of the clamping block 49. At the other end of the pivot 54 the lever 53 has an arm 60. The upper part 42 of the faucet device consists of a drive crank or tap 57, pivoting on a tap spindle 58. The spindle tap 58 supports an eccentric cam 59, which collaborates with the arm 60 of the lever. Figure 7 shows in continuous lines the situation in which the ends 56 of the bracketing arm 55 they are free of the pressure pivots 51, so that the spring 50 press the retaining block 49 butt up and the hose 34 is completely pinched by the clamp hose 52. When the tap 57 is turned according to the clockwise, eccentric cam 59 is pressed against arm 60 and cam 53 pivots counterclockwise. The 56 ends of arm 55 press down on pressure pivots 51 and consequently in the hose. Accordingly, the hose 34 is open and the drink can flow through the hose to the outlet tube 46. When the tap is tilted back the hose is clamped immediately and the outflow ceases. The upper part 42 of the faucet device can be attached to the bottom 41 by means of a locking mechanism 61.

The housing 1 of the apparatus has walls double, with a thermal insulation material 63 interposed between the outer wall 62 and the inner wall 15, which forms the wall of chamber 3 (Fig. 2). Accommodation 1 also houses the following parts: a cooling device 64, for example an element Peltier to cool the container 5. The cooling device has a cooling surface 65, in conductive contact direct thermal with the inner wall 15 of the chamber; the bomb previously indicated 19; a cooling fan for cool the heatsink of the cooling device and other parts electrical, for example a printed circuit board 67; a pressure controller to control the pressure in space pressurized 17; a temperature controller 69 to control the temperature of the cooling device; a switch of pump 70 to activate and deactivate pump 19, and a valve safety 71 to discharge the pressure in the pressurized space 17.

The device also has a tray to collect spilled liquid

The operation of both the switch of the pump 70 as the safety valve 71 is linked to the opening and closing of the cover 4 in the housing 1. A line 73 connect pressure controller 68 with line 18 between pump 19 and pressurized space 17. A line 74 extends from the pressure controller 68 to safety valve 71. In when the cover 4 is opened, the safety valve and the pressurized space 17 communicates with the outside (atmosphere) on lines 18, 73 and 74. Pressure is discharged into Pressurized space. Pump switch 70 deactivates the pump 19 when the lid 4 opens and activates the pump when the lid closes.

As we have already indicated, the upper part 42 of the fitting 6 is articulated with the part lower 41 and can be attached to said lower part by the locking mechanism 61. When the beverage vending machine is in use, that is when it is possible to serve drinks, it is not allowed the upper part 42 moves away from the lower part 41 because of otherwise the beverage supply hose 34 would already be pinched and the drink could come out. Tipping towards above the top part because a flange 75 of the lid is above the top in the closed state. The flange 75 It has a notch 76, which hooks over the top (see the Figure 1). The upper part 42 cannot be lifted until the lid has opened, after being unlocked. Conversely, the lid 4 cannot be closed until top 42 tilts on the bottom 41 since a side wall 77 of the upper part abuts against the flange 75 of the lid on the top position

It constitutes another security measure that the Pump switch 70 is not activated if it is not installed in the apparatus no beverage container 5 with a supply line of beverage 7. To this end, a detection mechanism 78 is provided in the inside of a lid 4 to detect the presence of a container. Said mechanism consists of a detection rod shaped of "L" 79. A spindle 80 is mounted transversely to said rod 79. Said spindle is rotatably mounted on the cover 4. The detection rod 79 can make a small movement in pivot on spindle 80. To this end, a support 81 extends on the detection rod 79 with wide clearance and is subject to the inside of the cover 4. The clearance between the support and the Detection rod limits the pivoting movement of the rod. The end of the spindle 80 incorporates an actuation pivot 82. Said actuation pin activates the pump switch 70. When a container 5 with its beverage supply line is present in the device and the lid is closed, the shortest arm of the detection rod 79 is adjacent to the line of beverage supply 7, which means that the spindle rotation and actuation pivot 82 acts on the Pump switch 70 and the pump turns on. Nevertheless, when no container with a line of beverage supply, or a container without line of supply, the spindle 80 with the detection rod 79 can lower, with the consequence that the actuation pivot 81 does not acts on the pump switch 69 and said switch does not It is powered.

The beverage vending machine is used from the Following way. It is assumed that there is no container in the device. The lid 4 is opened and a container full of drink. The locking wedges 10 move away. Once the container has reached to the bottom of the chamber, the wedges 10 move in again and hold the container. The top 42 of the fitting 6 is tilted upwards and the hose 34 is placed on the bottom 41 on the clamp of hose 52 and outlet tube 46 is inserted into channel 47 of the faucet device The upper part 42 swings over the bottom and fixed to it by the locking mechanism 61. At this time hose 34 is pinched and closed. Cover it can be closed and the pump switch 69 turns on automatically. They also turn on the device cooling 64 and cooling fan 66. Space pressurized 17 is progressively pressurized, raising the container 5. The sealing membrane is perforated and the drink is forced to enter the beverage supply line (hose). The liquid can be dosed after opening tap 57. Once After removing all the beverage from the container, the lid is opened. The switch of the pump immediately deactivates the pump and the valve opens safety 71, whereby the pressure in the space is discharged pressurized 17. Using the cranks 30, 31, the locking wedges 10 can be released and the empty container can be removed from the apparatus.

The embodiment described in this report Use air as a pressure medium to pressurize the container. How alternatively it is possible to use, for example, a pressure medium liquid. In addition, the flange 12 of the package described above is mount on a collar 11 connected in solidarity with the container. Obviously, said flange can be part of the wall of the Packaging directly, that is, it can be integral with it. In the present example the seal by means of the ring sealing 13 is effected in flange 12. However, said airtight closure can also be made on the wall of the self container. Instead of a beverage container in the form of a bottle with compressible walls, it is also possible to use other types of beverage containers in the apparatus according to the invention, to condition that they have at least one flexible deformable wall. In This case could be considered a membrane wall.
