SUMMARY OF THE INVENTION

In the above-mentioned conventional beverage preparation machine 101, since the syrup box 120 and the steel cylinder 109 are arranged outside the main body 102 of the preparation machine, for example, at the lower part of the installation table of the beverage preparation machine 101 or in the warehouse of the store, it is an exception to the rule. In addition to the installation space of the main body 102 of the current adjusting machine, the installation space of the syrup tank 120 is also required.

Furthermore, since the BIB 130 and the syrup tank 120 are installed in different places, the remaining amount of each concentrated stock solution must be checked, and the replacement operation of the BIB 130 and the replenishment operation of the syrup tank 120 must be performed at different places. Furthermore, the laying operation at the initial installation of the raw solution supply line 117 connecting the syrup tank 120 and the main body 102 of the present brewing machine, and the cleaning operation after installation are troublesome, and the installation cost and maintenance cost are increased.

In view of the above-mentioned facts, the technical problem to be solved by the present invention is to provide a container for encapsulating the liquid used in a liquid adjusting machine that can save space, confirm the remaining amount of liquid, facilitate replenishment operations, and maintain low installation and maintenance costs. .

The container according to the present invention is characterized in that a container for sealing the liquid used in a liquid conditioning machine for discharging the liquid from the container for sealing the liquid is characterized by comprising: a bag-shaped sealing portion for for encapsulating the liquid; an outflow part for outflowing the liquid to the outside is protruded from the encapsulation part, and the top end of the outflow part is provided with an outflow port, and the encapsulation part is deformed by an external force. The liquid flows out from the outflow port.

For example, a liquid conditioning machine for discharging the liquid from a container for encapsulating the liquid is a beverage preparation machine for discharging the concentrated stock liquid from a stock liquid container for encapsulating the concentrated stock solution, and the present invention relates to a liquid conditioning machine for discharging the concentrated stock liquid from the container for packing the liquid. The container used for the liquid conditioning machine to seal the liquid is suitable for packaging the concentrated stock solution container, not only the stock solution container for encapsulating the concentrated stock solution of non-carbonated beverages as a liquid, but also for encapsulating carbonic acid as a liquid. The stock solution container of the concentrated stock solution of the beverage is also accommodated in the storage part of the beverage preparation machine, and it is not necessary to install the syrup tank of the concentrated stock solution of the carbonated beverage outside the beverage preparation machine as conventionally, so that space saving can be achieved. Furthermore, since the laying operation and cleaning operation of the raw liquid supply line and the like are not required, the installation cost and the maintenance cost can be reduced.

In this case, unlike the conventional BIB, the original solution container can be used in the beverage dispenser itself instead of being housed in a box-shaped box, so that space saving in the box-shaped box can be achieved. It should be noted that, in the same storage space, since a larger stock solution container or more stock solution containers can be housed, relative space saving can be achieved.

Furthermore, since the unsealing operation of the box-shaped box like the conventional BIB becomes unnecessary, the replacement operation of the stock solution container becomes easy. Since the box-shaped box is not required, cost reductions in material costs and manufacturing costs can be achieved. Furthermore, since there is no box-shaped case, the work of discarding the emptied raw material container is also facilitated.

Not only the stock solution container for encapsulating the concentrated stock solution of non-carbonated beverages, but also the stock solution container for encapsulating the concentrated stock solution of carbonated beverages is also accommodated in the storage part of the beverage preparation machine, so it is not necessary to install the syrup tank for the concentrated stock solution of carbonated beverages as in the past. It is located outside the beverage dispenser, so that space saving can be achieved.

Since the concentrated raw liquid sealed inside can be made to flow out from the outflow port by a simple operation such as deformation of the sealing part, the configuration of the outflow mechanism of the concentrated raw liquid included in the beverage preparation machine can be simplified.

In the present invention, it is preferable that the sealing portion and the outflow portion are formed by bending a single flexible resin sheet or stacking a plurality of sheets, and then heat-sealing the peripheral portion.

Since the container can be sealed, there is no concern that outdoor air or microorganisms will be mixed inside, and it is easy to maintain the quality.

Since the container is formed of a resin-made sheet, deformation of the sealing portion for flowing out the liquid sealed inside can be easily performed.

In addition, since the container is made of a resin sheet, for example, the liquid enclosed inside can be easily cooled by cooling the container only from the outside by the cooling mechanism.

In the present invention, it is preferable that the outflow part is configured such that when the container is used in the liquid conditioning machine, the volume of the liquid enclosed in the outflow part is equal to the volume of the liquid flowing out from the liquid conditioning machine.

In the present invention, it is preferable that the encapsulation portion includes a transition portion in which a cross-sectional area in a direction orthogonal to the axial center direction of the outflow portion is smoothly reduced from the encapsulation portion to the outflow portion in a boundary region with the outflow portion. .

Since the outflow portion is set to have a smaller cross-sectional area in a direction perpendicular to the axial direction of the outflow portion than the sealing portion, the pressure loss in the boundary region between the sealing portion and the outflow portion tends to increase.

Due to the existence of the transition portion, the change in the cross-sectional area of the boundary region between the sealing portion and the outflow portion and the degree of expansion of the container caused by the liquid transition smoothly, thereby reducing pressure loss. In addition, since the shape change from the encapsulation portion to the outflow portion is smoothed by the transition portion, the occurrence of wrinkles in the boundary region between the encapsulation portion and the outflow portion is suppressed. As a result, the liquid enclosed in the sealing portion smoothly flows down to the outflow portion.

In the present invention, it is preferable that the encapsulation portion includes a concave portion that expands in a fan shape around the center of the transition portion and is recessed in the thickness direction of the encapsulation portion.

Since the outflow portion is set to have a smaller cross-sectional area in a direction perpendicular to the axial direction of the outflow portion than the sealing portion, the pressure loss in the boundary region between the sealing portion and the outflow portion tends to increase. Since the encapsulation portion is provided with the concave portion, the change in the cross-sectional area of the encapsulation portion and the outflow portion is smoothed in the concave portion, so that the pressure loss can be reduced. Therefore, the liquid enclosed in the sealing portion smoothly flows down to the outflow portion.

In this invention, it is preferable that the said sealing part is provided with the convex part which longitudinally cuts the said transition part, and the cross-sectional view in the direction orthogonal to the axial center direction of the said outflow part protrudes outward.

On the inner surface of the sealing portion, the internal pressure generated by the liquid sealed in the sealing portion acts on the outside of the sealing portion. At this time, since the internal pressure acts on the inner surface of the protruding portion, the sealing portion is stretched in the thickness direction, so that the liquid sealed in the sealing portion can surely flow down to the outflow portion.

In this invention, it is preferable that the lower end of the said convex part reaches the front-end|tip part of the said outflow part.

On the inner surface of the outflow portion, the internal pressure generated by the liquid flowing through the outflow portion acts on the outside of the outflow portion. At this time, since the internal pressure acts on the inner surface of the convex portion, the outflow portion is stretched in the thickness direction, so that the liquid flowing through the outflow portion can surely flow down to the outflow port.

In this invention, it is preferable that the said outflow part is comprised so that the cross section in the direction orthogonal to the axial center direction of the said outflow part is circular.

The liquid flowing through the outflow portion can surely flow down to the outflow port.

In this invention, it is preferable that the front-end|tip part of the said outflow part is provided with the linear reinforcement part parallel to the axial center direction of the said outflow part.

When the liquid flows out, the oscillating motion of the distal end portion of the outflow portion can be reduced by the reinforcing portion.

In the present invention, it is preferable that the sheet is formed of a resin having excellent transparency.

Simple identification of the liquid enclosed in the container, observation of the remaining amount, and detection of color change, turbidity, etc. become easy.

In this invention, it is preferable that the peripheral edge part of the said outflow part is provided with the notch part which can be utilized when forming the said outflow port in the peripheral part of the said front-end|tip part vicinity.

From the notch portion as a starting point, it is possible to easily form an open end serving as an outflow port at the distal end portion by cutting it with a finger sterilized with alcohol spray, scissors, or the like, for example.

In this invention, it is preferable that the peripheral part of the said sealing part is provided with the hanging hole for hanging the container on the hook provided in the said liquid conditioning machine in the peripheral part of the opposite side to the said outflow part .

The container can be accommodated in the liquid conditioning machine by a simple operation of hooking the hanging hole on the hook.

In the present invention, the liquid is preferably a beverage.

It is possible to configure a container for encapsulating the beverage for use in a beverage preparation machine that can save space, confirm the remaining amount of the beverage, and facilitate replenishment and maintenance.

In the present invention, it is preferable that the liquid is a concentrated stock solution that constitutes a beverage by mixing with a diluent.

It is possible to configure a container for encapsulating the concentrated stock solution for use in a beverage preparation machine that can save space, confirm the remaining amount of the concentrated stock solution, and facilitate replenishment and maintenance.

FIG. 3( a ) is a diagram showing the stock solution container 30 .

The stock solution container 30 includes a bag-shaped sealing portion 31 for sealing the concentrated stock solution, and an outflow portion 32 for discharging the concentrated stock solution to the outside, and is provided downwardly protruding from the bag-shaped sealing portion 31 . The peripheral part of the sealing part 31 is provided with the hanging hole 33 for hanging the raw liquid container on the hook 18 provided in the beverage preparation machine 1 in the peripheral part on the opposite side to the outflow part 32 . Moreover, in the peripheral part of the outflow part 32, the peripheral part in the vicinity of a front-end|tip part is provided with the notch part 34 which can be utilized when forming the outflow port 35. FIG.

The raw liquid container 30 is formed by superimposing two sheets of flexible resin-made sheets, and then heat-sealing the peripheral portion so that they cannot be peeled off.

Specifically, for example, the stock solution container 30 can be formed into a bag shape by stacking two sheets, heat-sealing the peripheral edge of the sealing portion 31 other than the outflow portion 32, and pouring the concentrated stock solution into the sealing portion 31, and then heat-sealing the outflow portion 32. the perimeter of the rim to form a liquid tightness. However, the method of sealing is not limited to this. For example, instead of filling from the outflow part 32 , it may be filled from the peripheral part of the sealing part 31 . In addition, it is preferable to perform manufacture of the raw solution container 30 in an inert gas atmosphere. After that, the hanging hole 33 and the cutout portion 34 are formed.

The sheet forming at least the inner surface of the raw solution container 30 is made of synthetic resin. The sheet, for example, is composed of a single-layer or Multi-layer synthetic resin composition.

From the viewpoint of excellent transparency, flexibility, and hygienic properties, and low cost, polyolefin resins are preferred.

Examples of polyolefin resins include polyethylene-based resins such as high-density polyethylene, medium-density polyethylene, high-pressure low-density polyethylene, linear low-density polyethylene, and ethylene-vinyl acetate copolymers, ethylene- Olefin-based elastic materials such as α-olefin random copolymers, polypropylene-based resins such as polypropylene, ethylene-propylene random copolymers, and α-olefin-propylene random copolymers, cyclic polyolefin resins, and the like. These resins can also be blended for improved performance. For the purpose of improving heat resistance or the like, it may be partially crosslinked.

In the case of a multi-layered sheet, a configuration in which no adhesive or the like is used is preferable.

The two sheets may be the same or different, but from the viewpoint of ease of heat sealing, it is preferable that at least the opposing surfaces are made of the same kind of resin. In addition, from the viewpoint of easiness of production and disposal, the same sheet is preferable, and a sheet composed of a single synthetic resin is more preferable.

The stock solution container 30 is formed of a synthetic resin having excellent transparency, so that easy identification of the enclosed concentrated stock solution, observation of the remaining amount, and detection of color change or turbidity can be facilitated.

The surface of the sealing portion 31 of the stock solution container 30 may be marked with marks showing the type, remaining amount, and expiration date of the packed concentrated stock solution.

The thickness of the sheet is preferably about 30 to 600 μm, and more preferably about 100 to 400 μm.

After almost all of the concentrated undiluted solution is discharged, the undiluted solution container 30 becomes a thin sheet, and therefore it can be folded into a small size for disposal.

As shown in FIG. 3( b ), by hanging the hanging hole 33 on the hook 18 provided inside the accommodating portion 4 of the main body 2 of the current conditioning machine, the raw solution container 30 configured as above has the outflow portion 32 in the The state below is hung. In this state, the lower end of the outflow portion 32 forms an open end as shown in FIG. 3( b ), and the notch portion 34 shown in FIG. The fingers or scissors are broken horizontally or obliquely, and the open end constitutes the outflow port 35 .

Next, the raw liquid outflow mechanism 5 will be described.

A crimping valve 41 is disposed on the sealing portion 31 side of the outflow portion 32 .

The pressure valve 42 is disposed on the outflow port 35 side of the outflow portion 32 .

The pinch valves 41 and 42 are configured such that, for example, the plunger driven by electromagnetic force controls the flow of the concentrated stock solution from the sealing portion 31 side to the outflow port 35 side by clamping or not clamping the outflow portion 32 .

The pinch valve 41 is a first valve body disposed in the flow path from the sealing portion 31 to the outflow portion 32 , and a mechanism for opening and closing the pinch valve 41 by driving the plunger of the pinch valve 41 as the first valve body The first valve body opening and closing mechanism is constituted.

The pinch valve 42 is a second valve body disposed in the flow path from the outflow portion 32 to the outflow port 35 , and a mechanism for opening and closing the pinch valve 42 by driving the plunger of the pinch valve 42 as the second valve body A second valve body opening and closing mechanism is formed.

The first valve body opening and closing mechanism and the second valve body opening and closing mechanism are controlled by an opening and closing control mechanism not shown, respectively, so that they do not become both the plunger of the pressure valve 41 and the plunger of the pressure valve 42 at the same time. The state where the outflow part 32 is not clamped. The first valve body, the second valve body, the first valve body opening and closing mechanism, the second valve body opening and closing mechanism, and the opening and closing control mechanism constitute the raw liquid outflow mechanism 5 .

When the first valve body, namely the pressing valve 41, and the second valve body, namely the pressing valve 42, are closed, the plungers of the pressing valve 41 and the pressing valve 42 clamp the outflow portion 32, and the clamped portion does not flow from the sealing portion. When the concentrated stock solution on the side of the outflow port 35 flows through, and the first valve body, namely the compression valve 41 and the second valve body, namely the compression valve 42, are opened, the plungers of the compression valve 41 and the compression valve 42 are not clamped. The outflow portion 32 is held, and the concentrated stock solution flows from the sealing portion 31 side to the outflow port 35 side.

The distance between the pinch valve 41 and the pinch valve 42 is preferably set so that after the pinch valve 41 and the pinch valve 42 are closed, the amount of concentrated stock solution stored in the outflow part 32 between them becomes a predetermined amount per outflow. The valves 41 and 42 can also function as a metering mechanism for the concentrated stock solution.

In addition, it is preferable that the accommodating part 4 is equipped with the pressure control means which discharges the pressurized gas supplied by the pressurized gas supply means.

The pressurized gas supply mechanism causes the inside of the housing portion 4 to be in a positive pressure state, so that the deformation of the sealing portion 31 is accelerated, and the concentrated undiluted liquid sealed inside is surely squeezed out to the outflow portion 32 . The pressurized gas supply mechanism is a first pressurization mechanism capable of pressurizing the sealing portion 31 from the outside.

As shown in FIG. 4( a ), by controlling the pressurized gas supply mechanism, the interior of the housing portion 4 is maintained at a positive pressure, and a predetermined pressing force is applied to the raw solution container 30 , and the pressure valve 42 is closed. , and when the pressing valve 41 is opened, the concentrated stock solution in the sealing part 31 flows from the sealing part 31 to the outflow part 32 by gravity together with the pressing force based on the positive pressure.

Then, as shown in FIG. 4( b ), when the pinch valve 41 is closed while the pinch valve 42 is kept closed, the flow of the concentrated stock solution from the sealing portion 31 to the outflow portion 32 is stopped.

Finally, as shown in FIG. 4( c ), when the pinch valve 42 is opened while the pinch valve 41 is kept closed, the concentrated raw liquid in the outflow part 32 flows out from the outflow port 35 to the outside.

In this way, the control of the raw liquid outflow mechanism 5 and the gas supply mechanism is appropriately performed, so that a predetermined amount of concentrated raw liquid is appropriately discharged from the raw liquid container 30 .

In addition, the outflow amount of the concentrated stock solution flowing out from the outflow port 35 can also be controlled by simultaneously controlling the pressing force applied by the first pressurizing mechanism in conjunction with the opening and closing control of the pinch valves 41 and 42 . At this time, the first pressurizing mechanism also functions as a measuring mechanism.

When the user operates the selection button corresponding to the desired beverage, the raw liquid outflow mechanism 5 corresponding to the operated selection button is controlled, and the concentrated liquid contained in the raw liquid container 30 is controlled. The raw liquid flows out from the outflow port 35, and at the same time, the diluent corresponding to the concentrated raw liquid in the drinking water or carbonated water is supplied from the drinking water supply line 8 or the carbonated water supply line 14, and the prepared beverage passes through the beverage discharge port 16. is supplied to cup C.

In the above-mentioned embodiment, the case where the first valve body is the pressure valve 41 and the second valve body is the pressure valve 42 has been described, but the first valve body and the second valve body, the first valve body is opened and closed The structures of the mechanism, the second valve body opening and closing mechanism, and the opening and closing control mechanism are not limited to this.

For example, as shown in FIGS. 5( a ) to 5 ( c ), the raw liquid outflow mechanism 5 may be configured to include a hose pump mechanism.

This hose pump mechanism includes a rotor 52 having a plurality of rollers 51 arranged at equal intervals in the circumferential direction and held rotatably, and a pressure receiving wall 53 sandwiching the outflow portion 32 between the rotor 52 .

By arranging the outflow portion 32 between the rollers 51 and the pressure-receiving wall 53 , the rotor 52 is rotated in a certain direction, and the plurality of rollers 51 press the outflow portion 32 against the pressure-receiving wall 53 in sequence. While moving, the concentrated undiluted liquid flows out from the outflow port 35 by one division of the adjacent rollers 51 at a time, that is, a predetermined amount at a time.

In addition, when the operation button is operated, the hose pump mechanism continues to rotate the rotor 52, so that the concentrated raw liquid can be continuously discharged.

When the rotor 52 is rotating, the rollers 51 and the pressure-receiving wall 53 abutting the outflow portion 32 are the first valve bodies arranged in the flow path from the sealing portion 31 to the outflow portion 32, or are arranged in the flow path from the outflow portion 32. The second valve body of the flow path from 32 to the outflow port 35, and the rotor 52 for moving the first valve body or the second valve body constitutes a first valve body opening and closing mechanism and a second valve body opening and closing mechanism for For example, a driver that rotates the rotor 52 constitutes an opening/closing control mechanism.

Each of the rollers 51 is arranged at a predetermined position in the circumferential direction of the rotor 52 in a state where the outflow portion 32 is not sandwiched between any of the rollers 51 and the pressure-receiving wall 53 .

The first valve body, the second valve body, the first valve body opening and closing mechanism, the second valve body opening and closing mechanism, and the opening and closing control mechanism constitute the raw liquid outflow mechanism 5 .

When the first valve body, the second valve body, that is, the roller 51 and the pressure receiving wall 53 are closed, the roller 51 and the pressure receiving wall 53 clamp the outflow portion 32, and the clamped portion does not flow from the sealing portion 31 to the outflow port. When the first valve body, the second valve body, that is, the roller 51 and the pressure receiving wall 53 are opened, the roller 51 and the pressure receiving wall 53 do not clamp the outflow part 32, and the flow from the sealing part 31 is carried out. The flow of the concentrated stock solution on the side of the side outflow port 35 .

For example, as shown in FIGS. 6( a ) to 6 ( c ), the raw liquid outflow mechanism 5 may be configured to include a finger pump mechanism.

The finger pump mechanism includes: fingers 61 arranged at equal intervals along the arrangement direction of the outflow portion 32 ; a pressure receiving wall 63 sandwiching the outflow portion 32 between the fingers 61 ; and a cam mechanism 62 for sequentially moving the fingers 61 forward and backward. .

It is constructed in the following manner: by disposing the outflow portion 32 between the fingers 61 and the pressure-receiving wall 63, each finger 61 is moved forward and backward in sequence, so that the outflow portion 32 is crushed by the generated peristaltic motion, so that the concentrated stock solution flows from the outflow port 35. It flows out by one phase amount of each finger 61 at a time, that is, a predetermined amount at a time.

In addition, when the operation button is operated, the finger pump mechanism continues the peristaltic movement of each of the fingers 61 , so that the concentrated stock solution can be continuously discharged.

Among the fingers 61 , the finger 61 arranged on the sealing part 31 side of the outflow part 32 is the first valve body arranged in the flow path from the sealing part 31 to the outflow part 32 , and among the fingers 61 , the outflow port of the outflow part 32 is the first valve body. The finger 61 arranged on the 35 side is the second valve body arranged in the flow path from the outflow portion 32 to the outflow port 35, and the cam mechanism 62 for moving the first valve body and the second valve body forward and backward constitutes the first valve body. The valve body opening and closing mechanism, the second valve body opening and closing mechanism, and, for example, a driver for driving the cam mechanism 62 constitute an opening and closing control mechanism.

The outflow portion 32 is not sandwiched between any of the fingers 61 and the pressure receiving wall 63 , and is moved forward and backward by the cam mechanism 62 .

The first valve body, the second valve body, the first valve body opening and closing mechanism, the second valve body opening and closing mechanism, and the opening and closing control mechanism constitute the raw liquid outflow mechanism 5 .

When the first valve body and the second valve body, that is, the finger 61 and the pressure-receiving wall 63 are closed, the finger 61 and the pressure-receiving wall 63 clamp the outflow portion 32, and the clamped portion does not move from the sealing portion 31 side to the outflow port 35 side. When the first valve body and the second valve body, that is, the finger 61 and the pressure-receiving wall 63 are opened, the finger 61 and the pressure-receiving wall 63 do not clamp the outflow part 32, and the outflow port from the encapsulation part 31 is not clamped. The flow through of the concentrated stock solution on the 35 side.

In addition, although not shown, the raw liquid outflow mechanism 5 may be configured to include an upper holding member disposed on the sealing portion 31 side of the outflow portion 32 and a cap member disposed on the outflow port 35 side of the outflow portion 32 . Lower clamping member.

The two clamping members are, for example, driven by an actuator, and by clamping the outflow portion 32 , the concentrated stock solution does not flow from the sealing portion 31 side to the outflow port 35 side, and by not clamping the outflow portion 32 . , so that the concentrated stock solution flows from the sealing portion 31 side to the outflow port 35 side.

The upper holding member is a first valve body disposed in the flow path from the sealing portion 31 to the outflow portion 32 , and the lower holding member is disposed in the passage from the outflow portion 32 to the outflow port 35 . The driver for opening and closing the first valve body and the second valve body constitutes a first valve body opening and closing mechanism and a second valve body opening and closing mechanism. The first valve body opening and closing mechanism and the second valve body opening and closing mechanism are controlled by an opening and closing control mechanism.

The opening and closing control mechanism controls the first valve body opening and closing mechanism and the second valve body respectively in a state that the upper holding member and the lower holding member do not hold the outflow portion 32 at the same time. Opening and closing mechanism.

The first valve body, the second valve body, the first valve body opening and closing mechanism, the second valve body opening and closing mechanism, and the opening and closing control mechanism constitute the raw liquid outflow mechanism 5 .

When the first valve body and the second valve body, that is, the upper clamping member and the lower clamping member are closed, the upper clamping member and the lower clamping member clamp the outflow portion 32, and the clamped portion The first valve body and the second valve body, ie, the upper holding member and the lower holding member, are opened without flowing the concentrated stock solution from the sealing portion 31 side to the outflow port 35 side, and the upper holding member is opened. The member and the lower holding member do not hold the outflow portion 32, so that the concentrated stock solution flows from the sealing portion 31 side to the outflow port 35 side.

Furthermore, although not shown, the raw liquid outflow mechanism 5 may be configured to include an upper bending mechanism capable of bending the outflow portion 32 on the sealing portion 31 side and a lower bending mechanism capable of bending the outflow portion 32 on the outflow port 35 side.

For example, the two bending mechanisms may be configured as follows: driven by an actuator, the outflow portion 32 is bent so that the concentrated stock solution does not flow from the side of the sealing portion 31 to the outflow port 35, and the outflow portion 32 is not bent, thereby preventing the flow of the concentrated stock solution from the side of the sealing portion 31 to the outflow port 35. The flow of the concentrated stock solution from the side of the sealing portion 31 to the side of the outflow port 35 is performed.

The upper bending mechanism is a first valve body disposed on the flow path from the sealing portion 31 to the outflow portion 32 , and the lower bending mechanism is a second valve body disposed in the flow path from the outflow portion 32 to the outflow port 35 . Two valve bodies, the driver for opening and closing the first valve body and the second valve body constitutes a first valve body opening and closing mechanism and a second valve body opening and closing mechanism. The first valve body opening and closing mechanism and the second valve body opening and closing mechanism are controlled by an opening and closing control mechanism.

The opening and closing control mechanism controls the first valve body opening and closing mechanism and the second valve body opening and closing mechanism, respectively, so that the upper bending mechanism and the lower bending mechanism do not bend the outflow portion 32 at the same time. .

The first valve body, the second valve body, the first valve body opening and closing mechanism, the second valve body opening and closing mechanism, and the opening and closing control mechanism constitute the raw liquid outflow mechanism 5 .

When the first valve body and the second valve body, that is, the upper bending mechanism and the lower bending mechanism are closed, the upper bending mechanism and the lower bending mechanism bend the outflow portion 32, and the bent portion is not removed from the sealing portion. 31 When the concentrated stock solution on the side of the outflow port 35 flows, when the first valve body and the second valve body, that is, the upper bending mechanism and the lower bending mechanism are opened, the upper bending mechanism and the lower bending mechanism are not. The outflow portion 32 is bent, and the concentrated stock solution flows from the sealing portion 31 side to the outflow port 35 side.

In the above-described embodiment, the first pressurizing mechanism is described as follows: the accommodating portion 4 for accommodating the raw solution container 30 is constituted by a closed space, and the cylinder 9 is injected into the cylinder 9 by the pressurized gas supply mechanism connected to the closed space. The carbon dioxide gas is supplied as pressurized gas, and the inside of the housing portion 4 is in a positive pressure state, so that the concentrated undiluted liquid sealed in the sealing portion 31 is extruded to the outflow portion 32, but is not limited to this.

The first pressurizing mechanism may be configured to press the raw solution container 30 by supplying carbon dioxide gas in the cylinder 9 to a gas bag provided adjacent to the raw solution container 30 in the housing portion 4 to expand it. In addition, instead of the air bag, it may be constituted by a water bag that expands by supplying cooling water. At this time, the concentrated stock solution enclosed in the stock solution container 30 can also be cooled by the cooling water supplied to the water bag. By controlling the degree of squeezing by the air bag or the water bag, it is also possible to control the outflow amount of the concentrated dope solution flowing out from the outflow port 35 .

The first pressurizing mechanism is composed of a pressurizing member provided adjacent to the raw solution container 30 in the accommodating portion 4 , and may be configured by moving the pressurizing member toward the raw solution container 30 to press the raw solution container 30 . It should be noted that the movement of the pressurizing member may be performed mechanically by an actuator or hydraulically, or may be performed by the elastic force of an elastic body such as a spring and a sponge.

In addition, the movement of the pressing member may be performed by the self-weight of the pressing member. In this case, the raw solution container 30 may be placed without being hung in the housing portion 4 , and a pressurizing member may be placed above the raw solution container 30 placed in the housing portion 4 .

In addition, the first pressurizing mechanism may be configured to extrude the concentrated stock solution by twisting the sealing portion 31 .

The second pressurizing mechanism may have the same configuration as the first pressurizing mechanism described above, and a form in which the portion sandwiched between the first valve body and the second valve body in the outflow portion 32 is pressurized from the outside may be provided. The roller 51 shown in Figs. 5(a) to 5(c) or the fingers 61 shown in Figs. 6(a) to 6(c) can also function as a second pressing mechanism. In addition, the second pressurizing mechanism may be constituted by a pair of rollers arranged on both surfaces of the outflow portion 32 . By gripping the outflow part 32 by a pair of rollers, and rolling it from top to bottom, the concentrated stock solution can be discharged. When the first valve body is closed, by operating the second pressurizing mechanism when the second valve body is open, the concentrated raw liquid of the portion sandwiched by the first valve body and the second valve body can be more reliably flow out.

It should be noted that the beverage preparation machine 1 may not include the above-mentioned first pressurizing mechanism and second pressurizing mechanism. Constructed by its own weight. A flexible pipe body passing through at least the first valve body and the second valve body can be inserted into the outflow portion 32 . The first valve body and the second valve body close the outflow part 32 together with the first flexible pipe body, and when it is opened later, the concentrated stock solution of the sealing part 31 is forcibly sent to the outlet even without the first pressing mechanism. The outflow portion 32 may be opened by the restoring force of the flexible pipe body.

In addition, the raw liquid outflow mechanism 5 may be a structure in which the concentrated raw liquid flows out from the outflow port 35 by forcibly opening and closing the opening and closing mechanism of the outflow portion 32 of the raw liquid container 30 .

For example, as shown in FIGS. 7( a ) to 7 ( c ), the opening and closing mechanism includes a pair of push-pull members 71 , 72 , 73 or a pair of push-pull members 71 , 72 , and 73 protruding integrally on both surfaces of the outflow portion 32 .

Specifically, the push-pull member 71 is disposed on the sealing portion 31 side of the outflow portion 32 .

A push-pull member 73 is disposed on the outflow port 35 side of the outflow portion 32 .

A push-pull member 72 is arranged between the push-pull member 71 and the push-pull member 73 .

The push-pull members 71 , 72 , and 73 forcibly open and close the outflow portion 32 by pushing and pulling the outflow portion 32 , for example, by an actuator, thereby controlling the flow of the concentrated stock solution from the sealing portion 31 side to the outflow port 35 side.

The push-pull member 71 is a first valve body disposed on the flow path from the sealing portion 31 to the outflow portion 32 , and an actuator that pushes and pulls the push-pull member 71 as the first valve body constitutes a first valve body opening and closing mechanism.

The push-pull member 73 is a second valve body disposed on the flow path from the outflow portion 32 to the outflow port 35 , and an actuator that pushes and pulls the push-pull member 73 as the second valve body constitutes a second valve body opening and closing mechanism.

The push-pull member 72 is a third valve body disposed between the first valve body and the second valve body, and an actuator that pushes and pulls the push-pull member 72 as the third valve body constitutes a third valve body opening and closing mechanism.

The first valve body opening and closing mechanism to the third valve body opening and closing mechanism are respectively controlled by an opening and closing control mechanism (not shown), so that all the push-pull members 71 to 73 do not open the outflow portion 32 at the same time. The first valve body to the third valve body, the first valve body opening and closing mechanism to the third valve body opening and closing mechanism, and the opening and closing control mechanism constitute the raw liquid outflow mechanism 5 .

When the first valve body is the push-pull member 71 , the second valve body is the push-pull member 73 , and the third valve body is the push-pull member 72 , when the push-pull member 71 , the push-pull member 73 , and the push-pull member 72 close the outflow portion 32 , the closed Part of the concentrated stock solution does not flow from the side of the sealing portion 31 to the side of the outflow port 35. When the first valve body is the push-pull member 71, the second valve body is the push-pull member 73, and the third valve body is the push-pull member 72, when the push-pull member 72 is opened, the push-pull member 72 is opened. The member 71 , the push-pull member 73 , and the push-pull member 72 open the outflow portion 32 , so that the concentrated stock solution flows from the sealing portion 31 side to the outflow port 35 side.

The distance between the push-pull member 71 and the push-pull member 73 is preferably set so that the pair of push-pull members 71 and 73 is pushed so that the package portion 31 side of the outflow portion 32 and the outflow port 35 are closed, and the paired push-pull member 71 and 73 are pulled apart. When the member 72 opens the part where the push-pull member 72 of the outflow portion 32 is arranged, the amount of the concentrated stock solution stored in the outflow portion 32 becomes a predetermined amount per outflow, and the push-pull members 71, 72, 73 also serve as the The measurement agency plays a role.

As shown in FIG. 7( a ), even if the sealing portion 31 is not pressed by the first pressing mechanism, when the push-pull members 72 and 73 are closed, when the push-pull members 71 are opened, the force of gravity and the opening of the push-pull members 71 are separated. Together with the generated suction force to the outflow part 32 , the concentrated raw liquid in the sealing part 31 flows to the outflow part 32 .

Then, as shown in FIG. 7( b ), when the push-pull member 71 is closed while the push-pull member 73 is closed and the push-pull member 72 is opened, the flow of the concentrated stock solution from the sealing portion 31 to the outflow portion 32 is stopped.

Finally, as shown in FIG. 7( c ), when the push-pull member 73 is opened while the push-pull member 71 is kept closed, the concentrated raw liquid in the outflow portion 32 flows out from the outflow port 35 to the outside. In addition, the push-pull member 72 can also be closed in this state. At this time, the push-pull member 72 also functions as a second pressing mechanism. When the push-pull member 71 of the first valve body is closed, the first valve body and the second valve body can be sandwiched by operating the second pressurizing mechanism when the push-pull member 73 of the second valve body is open. A portion of the concentrated stock solution flows out more reliably.

In this way, the control of the raw solution outflow mechanism 5 is appropriately performed, so that a predetermined amount of concentrated raw solution is appropriately discharged from the raw solution container 30 .

In short, the first valve body and the second valve body are provided in the beverage dispenser 1 , but the valve body that opens and closes the outflow portion 32 may be provided on the beverage dispenser 1 side or on the raw liquid container 30 side.

Furthermore, the first valve body may be provided on the side of the beverage dispenser 1 , and the second valve body may be provided on the side of the raw liquid container 30 .

In the above-described embodiment, it has been described that the pressure valves 41 and 42, the hose pump mechanism, the finger pump mechanism, and the push-pull members 71, 72, and 73 can also function as the metering mechanism for the concentrated stock solution. The following configurations are possible.

Below the outflow port 35 , a metering mechanism for metering the concentrated stock solution flowing out from the outflow port 35 may be additionally provided.

For example, a suction mechanism that is attached to the outflow port 35 and sucks a predetermined amount of concentrated stock solution from the outlet port 35 and discharges it can flow out a predetermined amount of concentrated stock solution by controlling the discharge amount discharged by the suction mechanism.

In addition, it is also possible to measure the concentrated stock solution by a load cell mounted on the cup holder 6 for detecting the weight of the concentrated stock solution flowing out into the cup C. When a predetermined amount of concentrated stock solution is detected to flow out into the cup C, the control of the outflow of the concentrated stock solution can be stopped.

In the above-mentioned embodiment, the case where the raw solution container 30 is made liquid-tight by stacking two flexible resin sheets and then heat-sealing the peripheral edge part so that they cannot be peeled off has been described, but the present invention is not limited to this. In addition, in the following description, a part of description is abbreviate|omitted about the same structure as the structure already mentioned.

For example, as shown in FIG. 8 , the raw solution container 30 may be formed of a single flexible resin sheet. At this time, the stock solution container 30 can be obtained by bending one sheet, heat-sealing the peripheral edge of the sealing portion 31 other than the outflow portion 32 to form a bag shape, pouring the concentrated stock solution into the sealing portion 31, and heat-sealing the outflow portion 32 The perimeter of the liquid is thus formed. Since the raw liquid container 30 is made of one sheet, compared with the case of being made of a plurality of sheets, there are fewer places for heat sealing, and the cost is also low.

Further, as shown in FIG. 9 , the raw solution container 30 may further include a cover portion 36 that further covers the sealing portion 31 . The raw solution container 30 has a two-layer structure, and includes a pressurized gas injection part 37 in the cover part 36 . By injecting pressurized gas from the injection part 37 into the space 38 between the sealing part 31 and the cover part 36 , the inside of the space 38 is in a positive pressure state, and the concentrated raw solution sealed in the sealing part 31 can be surely squeezed to the outflow part 32 out. At this time, the cover portion 36 serves as a first pressurizing mechanism capable of pressurizing the sealing portion 31 from the outside. Carbon dioxide gas in the cylinder 9 may also be used as the pressurized gas. It should be noted that the pressurized gas supplied by the pressurized gas supply mechanism is not limited to the carbon dioxide gas in the cylinder 9 . That is, the pressurized gas supply mechanism may be constituted by a fan, a blower, or a piston. At this time, gas such as air is compressed and supplied as pressurized gas.

At this time, the stock solution container 30 is obtained by stacking four sheets, heat-sealing the peripheral edge portion of the sealing portion 31 other than the outflow portion 32 and the peripheral portion of the cover portion 36 to form a bag shape, and pouring the concentrated stock solution into the sealing portion 31, The peripheral edge portion of the outflow portion 32 is heat-sealed to be liquid-tight.

In addition, as shown in FIG. 10, the raw liquid container 30 may be formed of one sheet of flexible resin. At this time, the raw solution container 30 can be obtained by rolling up one sheet into a cylindrical body, heat-sealing the opposing end portions, and then heat-sealing all the peripheral portions of the sealing portion 31 other than the outflow portion 32 by heat-sealing. One end of the opening of the cylindrical body is formed into a bag shape, and after the concentrated stock solution is injected into the sealing part 31 , the other end of the opening of the cylindrical body constituting the peripheral part of the outflow part 32 is heat-sealed to form a liquid tightness.

As shown in FIG. 3( b ), for example, by suspending the hanging hole 33 on the hook 18 provided in the accommodating part 4 of the main body 2 of the current conditioning machine, any raw liquid container 30 becomes the outflow part 32 in the position The state below is hung. In this state, for example, the lower end of the outflow portion 32 is cut horizontally or obliquely with a finger sterilized by alcohol spray, scissors, etc., to form an open end, and the open end constitutes the outflow port 35 .

It should be noted that any stock solution container 30 may be configured such that the tip portion of the outflow portion 32 is formed in the shape of a bottle mouth portion having an outflow port 35, and an attached cap is screwed to the bottle mouth portion so that the outflow port 35 is closed. seal. In addition, a safety valve (valve body) that opens when a predetermined pressure is applied to the outflow port 35 may be provided.

At this time, the hanging hole 33 of the raw solution container 30 is hung on the hook 18 provided in the accommodating part 4 of the main body 2 of the current conditioning machine, and the outflow part 32 is hung downward, and the outflow opening 35 is exposed by opening the cover. .

When the outflow port 35 is provided with a safety valve, the beverage dispenser 1 includes any of the first valve bodies described above, and the safety valve can also function as a second valve body. In addition, the 2nd pressurization mechanism which applies predetermined pressure which can open a 2nd valve body can also function as a 2nd valve body opening-closing mechanism.

It should be noted that any raw solution container 30 may be inserted in advance into the inner circumference of the outflow portion 32 with an elastic hose having a length from the outflow port 35 to the sealing portion 31 , or may be inserted after the raw solution container 30 is opened. This is particularly effective from the viewpoint of stably flowing out the concentrated stock solution in the stock solution container 30 when the first pressurizing mechanism and the second pressing mechanism are not provided.

In addition, instead of the above-mentioned hose, or in addition, an elastic hose of at least a length from the outflow port 35 to the sealing portion 31 or between the outflow port 35 and the sealing portion 31 is pre-installed on the outer periphery of the outflow portion 32 of the raw solution container 30 . An elastic ring is pre-installed in the appropriate position of the sump, and it can also be installed after the lid of the raw liquid container 30 is opened.

In this way, by using an elastic hose or ring for the outflow portion 32 of the raw solution container 30, and using an easily stretchable or elastic member such as rubber or resin for at least a part of the outflow portion 32, it is possible to control a certain amount of stability with a simple structure. outflow.

The raw solution container 30 may further include the following structures. In addition, in the following description, the same code|symbol is attached|subjected to the structure corresponding to the structure already mentioned.

Fig. 12 to Fig. 14 show a stock solution container 30 according to another embodiment of the stock solution container 30 shown in Fig. 3(a).

The raw liquid container 30 includes a transition portion 80 in the boundary region between the sealing portion 31 and the outflow portion 32 .

The transition portion 80 is configured so that the cross-sectional area in the direction orthogonal to the axial center direction of the outflow portion 32 is smoothly reduced from the sealing portion 31 to the outflow portion 32 .

Since the outflow portion 32 is set to have a smaller cross-sectional area in a direction orthogonal to the axial direction of the outflow portion 32 than the sealing portion 31 , pressure loss in the boundary region between the sealing portion 31 and the outflow portion 32 tends to increase. By providing the transition portion 80 in such a place, the change in the cross-sectional area of the boundary region between the sealing portion 31 and the outflow portion 32 and the expansion of the stock solution container 30 due to the concentrated stock solution are smoothly transitioned, so that pressure loss can be reduced. In addition, since the transition portion 80 smoothly changes the shape from the sealing portion 31 to the outflow portion 32 , it is possible to suppress the occurrence of wrinkles in the boundary region between the sealing portion 31 and the outflow portion 32 . As a result, the concentrated stock solution enclosed in the sealing part 31 flows smoothly to the outflow part 32 .

Furthermore, as shown in FIG. 12 , the encapsulation portion 31 includes a concave portion 81 that expands in a fan shape around the center of the transition portion 80 and is recessed in the thickness direction of the encapsulation portion 31 as shown in FIG. 13 .

Furthermore, as shown in FIG. 12 , the encapsulation part 31 is provided with a longitudinal transition part 80 , and as shown in FIG. 13 , the cross section in the direction perpendicular to the axial center direction of the outflow part 32 is viewed as a protrusion that protrudes outward. Section 82. As shown in FIGS. 12 and 14 , the upper end of the convex portion 82 reaches a position higher than the concave portion 81 , and the lower end thereof reaches the distal end of the outflow portion 32 .

The concave portion 81 and the convex portion 82 can be obtained by molding the sheet constituting the raw solution container 30 by preliminarily hot pressing or the like.

Since the outflow portion 32 is set to have a smaller cross-sectional area in a direction orthogonal to the axial direction of the outflow portion 32 than the sealing portion 31 , pressure loss in the boundary region between the sealing portion 31 and the outflow portion 32 tends to increase. Since the encapsulation portion 31 is provided with the concave portion 81 , the change in the cross-sectional area of the encapsulation portion 31 and the outflow portion 32 in the concave portion 81 is smoothed, so that the pressure loss can be reduced. Therefore, the concentrated undiluted solution encapsulated by the encapsulation part 31 flows down smoothly to the outflow part 32 .

In addition, on the inner surfaces of the sealing part 31 and the outflow part 32 , the internal pressure generated by the concentrated stock solution enclosed in the sealing part 31 or the concentrated stock solution flowing through the outflow part 32 acts toward the outside of the sealing part 31 or the outflow part 32 . At this time, since the inner pressure acts on the inner surface of the convex portion 82, the sealing portion 31 and the outflow portion 32 are stretched in the thickness direction, so the concentrated stock solution enclosed in the sealing portion 31 surely flows down to the outflow portion 32, and simultaneously flows through the outflow portion 32. The liquid in the outflow portion 32 surely flows down to the outflow port 35 .

As shown in FIG. 12 , the distal end portion of the outflow portion 32 is provided with a plurality of linear reinforcing portions 83 that are parallel to the axial center direction of the outflow portion 32 .

The reinforcing portion 83 can be obtained by molding the sheet constituting the stock solution container 30 by preliminarily hot pressing or the like.

The reinforcement part 83 can reduce the vibration of the front-end|tip part of the outflow part 32 at the time of outflow of a concentrated raw liquid.

It should be noted that the raw liquid container 30 does not need to include all of the concave portion 81, the convex portion 82, and the reinforcing portion 83 at the same time, and may include only any one of the concave portion 81, the convex portion 82, and the reinforcing portion 83, or the concave portion 81 and the convex portion. 82 and two of the reinforcing parts 83 are combined.
