FIG. 13 is a sectional view showing details of the internal structure of the upper half of the water server 1 according to the first embodiment of the present invention.

As shown in FIG. 1, the water server 1 according to the first embodiment of the present invention includes a main body 2 and a bottle holder 3 set on the upper portion of the main body 2. A cooling tank 4 for cooling the beverage liquid and a heating tank 5 for warming the beverage liquid are built in the main body 2, and a cooled beverage liquid or a heated beverage liquid is supplied to the front 2. Two supply ports 6 and 7 are provided. Here, although the case where drinking water is used as a drinking liquid is described, it is possible to use not only drinking water but also other drinking liquids.

In the cooling tank 4, the drinking water is cooled to a predetermined temperature by a cooling device built in the main body 2, and in the heating tank 5, the drinking water is warmed to a predetermined temperature by a heater built in the main body 2. Here, the capacity of the cooling tank 4 is 2.2 L, the capacity of the heating tank 5 is 2 L, the heating tank 5 is disposed under the cooling tank 4, and the drinking water sent to the cooling tank 5 Is configured to flow through the heating tank 5. The supply ports 6 and 7 are divided into a supply port 6 for supplying cold water and a supply port 7 for supplying hot water. However, a structure may be adopted in which cold water and hot water are switched by one supply port.

As shown in FIG. 13, the upper opening of the main body 2 closes the upper opening of the main body 2, holds the bottle holder 3, and allows drinking water to flow out from the bottle holder 3 to the cooling tank 4. A mortar-shaped packing holder 8 is provided, and the packing holder 8 is connected to the cooling tank 4. As shown in FIG. 2, a cylindrical recess 32 is formed at the center of the mortar-shaped portion of the packing holder 8, and an insertion rod 25 is installed at the center of the recess 32, and further surrounds the recess 32. A cylindrical connecting portion 24 connected to the opening of the cooling tank 4 is provided. A packing 14 is used for connection between the connection portion 24 of the packing holder 8 and the opening of the cooling tank 4 in consideration of water blocking.

As shown in FIG. 3, the packing 14 has a ring shape, and an inner peripheral surface is provided with a groove 26 that fits into the connecting portion 24, and an outer peripheral surface is provided with two upper and lower flanges 27 and 28, As for the said collars 27 and 28, the outer periphery of the upper stage collar 27 is formed larger than the lower stage collar 28. As shown in FIG. 4 (a), the packing 14 is first attached so that the lower end of the connecting portion 24 is fitted into the groove 26, and then the packing holder 8 is attached to the packing holder 8. Inserted from above so that the outer periphery of the packing 14 contacts the inner peripheral surface of the opening of the cooling tank 4 and is set in the opening of the main body 2.

Then, as shown in FIG. 4B, both the two-stage eaves 27 and 28 are deformed upward, and the water-stopping property between the cooling tank 4 and the packing holder 8 is ensured. In particular, by using the two-stage ridges 27 and 28, the waterstop is further improved. When the cooling tank 4 is filled with drinking water, the drinking water is stored up to the connecting portion between the packing holder 8 and the cooling tank 4. Is required to be watertight.

As shown in FIG. 5, the bottle holder 3 includes a side wall, a mortar-shaped bottom surface, a cylindrical bottom portion 15 provided at the center of the bottom surface, and a lid 13. The lid 13 is provided with a recess to form a handle. The bottom 15 of the bottle holder 3 is provided with an opening at the center of the upper surface, and the bottom is an opening. A hole is formed in the plastic bag 10 containing drinking water in the opening on the upper surface, and the drinking water is the main body. 2 is attached to the cooling tank 4, and the check valve 16 that opens when the insertion rod 25 provided in the packing holder 8 is inserted into the opening of the bottom 15 can be removed. Is attached. The bottle holder 3 is necessary for holding the plastic bag 10 because it is soft, and also serves to prevent the drinking water inside from flowing out to the surroundings if the plastic bag 10 is torn. And it is also necessary to reduce the amount of drinking water in the plastic bag 10 directly touching the outside air.

The check valve 16 includes a cap 33 that closes the opening of the bottom surface of the bottom portion 15 of the bottle holder 3 and a valve 34 that opens and closes a hole provided in the center of the cap 33, and the cap 33 is formed of the bottle holder 3. Is detachably attached to the bottom portion 15. In the state where the bottle holder 3 is not set in the packing holder 8, as shown in FIG. 5, the check valve 16 is in a state where the valve 34 is fitted in the hole of the cap 33 and the check valve 16 is closed. Even if drinking water remains in the bottom portion 15, it does not leak from the hole of the check valve 16.

However, when the bottle holder 3 is set in the packing holder 8, the insertion rod 25 is inserted into the hole of the check valve 16, the valve 34 of the check valve 16 is fitted at the tip of the insertion rod 25, and the cap 33 The check valve 16 is opened and the upper portion of the insertion rod 25 is inserted into the bottom portion 15.

Since the insertion rod 25 is provided with a passage inside, and an opening communicating with the passage is provided on a side surface of a portion to be inserted into the inside of the bottom portion 15, the insertion rod 25 is reversed as described above. In a state where the stop valve 16 is opened and inserted into the inside of the bottom portion 15, the drinking water in the bottom portion 15 flows from the opening of the insertion rod 25 to the cooling tank 4 through the internal passage.

When the bottle holder 3 is removed from the packing holder 8, the insertion rod 25 is removed from the hole provided in the cap 33 of the check valve 16, so that the valve 34 fitted to the tip of the insertion rod 25 is the cap 33. The check valve 16 is in a closed state, and even if drinking water is contained in the bottom portion 15, it does not flow out from the hole of the cap.

As shown in FIGS. 6 and 7, the needle 9 has a cylindrical shape with a pointed tip and a body portion 17 having two passages 19 and 20 that are partitioned in a vertical direction by a partition wall 30 inside and the bottle holder 3. It consists of a flange 18 that engages and is fixed to the upper surface of the bottom 15. A cylindrical portion having a concave side surface is provided below the flange portion 18, and when the needle 9 is attached to the upper surface of the bottom portion 15, a ring 29 is fitted into the concave portion, thereby Ensure water stop.

The two passages 19 and 20 include a drinking water passage 19 connected from an opening on the bottom surface of the main body portion 17 to a first opening 21 provided above the flange on the side surface of the main body portion 17, and a bottom surface of the main body portion 17. The air passage 20 is connected from the second opening 22 provided below the opening or the side flange 18 to the third opening 23 provided above the side flange 18 of the main body 17.

The tip of the main body portion 17 of the needle 9 has a sharp shape and is symmetrical in the cross-sectional view of FIG. 7, but the half surface of this tip is scraped to form a step as shown in FIGS. When the provided needle 9 ′ that is asymmetrical is used, when the needle 9 ′ is inserted into the plastic bag 10, the pressure concentrates on one side and can be smoothly inserted into the plastic bag 10. Further, when the hole is formed in the plastic bag 10, the plastic bag 10 is easily adhered to the tip of the needle 9 'without tearing the hole.

In order to set the bottle holder 3 in the packing holder 8, the bottom 15 of the bottle holder 3 is inserted into the recess 32 of the packing holder 8. At this time, positioning is performed so that the insertion rod 25 of the packing holder 8 is inserted into a hole provided in the bottom surface of the bottom portion 15 of the bottle holder 3. When the bottle holder 3 is set in the packing holder 8 in this way, the check valve 16 is opened and the state shown in FIG. 8 is obtained.

As described above, the bottle holder 3 and the packing holder 8 can be easily removed, and the needle 9 and the check valve 16 attached to the bottle holder 3 and the insertion attached to the packing holder 8. Since all the rods 25 are also removable, the cleaning is easy, and the water server 1 can be used in a constantly clean state by periodically disassembling and cleaning.

The drinking water in the plastic bag 10 is initially the drinking water passage 19 of the needle 9 inserted into the plastic bag 10 through a hole opened by the needle 9, as shown by an arrow in FIG. And flows through the air passage 20 to the bottom 15 of the bottle holder 3. The drinking water at this time flows from the first opening 21 and the third opening 23 to the two openings on the bottom surface of the needle 9, and the air passage 20 is used as a drinking water passage.

The drinking water that has flowed to the bottom 15 of the bottle holder 3 through the needle 9 has closed the hole of the cap 33 of the check valve 16 by the insertion rod 25 as shown by the arrow in FIG. Since the check valve 16 is in an open state by being moved upward, the check valve 16 flows from the side opening of the insertion rod 25 through the internal passage to the cooling tank 4. While there is a large amount of drinking water in the plastic bag 10 and a certain amount of drinking water flows, the bottom 15 is almost full of drinking water, and the second opening 22 is also temporarily stored. Located below the surface of drinking water.

When the drinking water in the plastic bag 10 decreases, the drinking water temporarily stored in the bottom 15 gradually decreases. When the drinking water temporarily stored in the bottom portion 15 becomes a predetermined amount or less, the second opening 22 is above the surface of the drinking water temporarily stored in the bottom portion 15 as shown in FIG. become. Then, as indicated by an arrow A in FIG. 10, the air existing in the bottom portion 15 or the air existing in the cooling tank 4 flows from the second opening 22 and passes through the air passage 20 and the air. Air flows into the third opening 23, and air flows into the plastic bag 10 from the third opening 23 as shown by an arrow B in FIG. At this time, the drinking water in the beverage use passage 19 is the same as before, and the vinyl has become difficult to flow in a state close to a vacuum due to the air entering the plastic bag 10 that only contained drinking water. Almost all the drinking water remaining in the bag 10 can be sent out to the cooling tank 4.

Thus, although the air passage 20 initially allows drinking water to pass therethrough, the drinking water in the plastic bag 10 can be almost used up by allowing air to pass conversely when drinking water is reduced. As a specific example, the amount of remaining water is about 20 ml, which is significantly reduced to about 1/5 of the remaining amount of water of 100 ml of a conventional water server using a PET bottle. Thereby, when supplying especially expensive drinking water etc., reducing a residual water amount significantly brings a big merit also for a user. In addition, the air sent into the plastic bag 10 is the air existing in the bottom 15 or the cooling tank 4 and does not directly enter the outside air. Therefore, when the outside air is introduced by opening a hole in the plastic bag 10. Compared with hygiene, the effect is excellent.

The plastic bag 10 containing drinking water used for the water server 1 has a two-layer structure composed of an inner layer and an outer layer using materials such as polyethylene having different properties, or an intermediate layer 3 provided between the inner layer and the outer layer. Layered vinyl is used. Since the inner layer is in contact with the beverage liquid, a material suitable for the beverage liquid is used, and the outer layer has high strength and impact resistance. When the needle 9 is inserted, the surface of the needle 9 is not broken by the impact. It is preferable to use a material that opens a hole while clinging to.

Here, a plastic bag made of vinyl using low density polyethylene for the inner layer, unstretched polypropylene for the outer layer, and nylon for the intermediate layer is used. When such a plastic bag 10 is used, it is possible to ensure strength that is not torn even when subjected to an impact during transportation. Further, after the hole is made with the needle 9, the vinyl around the hole becomes the needle. It becomes possible to prevent the drinking water from leaking from around the hole to the bottle holder.

Moreover, since the outer layer or intermediate | middle layer of the plastic bag 10 can be printed, the kind and property of the drinking water in the plastic bag 10, or other advertisements can also be printed. In the case of a conventional bottle, a method of winding a printed film around the bottle surface is used, but printing can be performed at a lower cost than that.

When drinking water is put in a plastic bag 10 and delivered to a user, for example, three plastic bags 10 containing 9 L of drinking water are put in one cardboard and delivered. As a result, the user can recycle the empty cardboard and the plastic bag 10 as recyclable waste, and the user can fold it small until it is disposed of, so no extra space is required. And it is possible to order new drinking water at any time without having to have it collected like a conventional bottle, and to transport overseas or order foreign water by packing in cardboard. Is also possible.

Next, a method for using the water server 1 will be described. As described above, to the user of the water server 1 of the present invention, three plastic bags 10 containing about 9 L of drinking water are packed in one cardboard and delivered.
