When the inner container becomes empty, it can be replaced with a new inner container filled with drinking liquid, and the compressed gas pressure is applied to the drinking liquid in the inner container via the compressible airtight inner container. This is characterized in that the quality of the stored beverage can be maintained over a long period of time by preventing the beverage from being exposed to the gas in the outer container.

[Embodiment 1] An embodiment of the first invention will be described in detail below with reference to FIGS. 1 and 2.

FIG. 1 shows a vertical cross-sectional view of the beverage liquid supply device of this embodiment, and the inside of the cylindrical outer container 6 has an external shape that can be taken in and out through the upper opening 6a, and a part of the upper wall or A completely open inner container 7 for storing syrup is housed therein.

The opening 6a of the outer container 6 is connected to the lid 9 through the O-ring 8.
It is closed airtight. A gas introduction pipe lO communicating with the inside of the outer container 6 is inserted through the lid body 9, and is configured to introduce compressed carbon dioxide gas into the outer container 6 from a carbon dioxide gas cylinder (not shown) through the gas introduction pipe 10. ing.

Separately, a syrup extraction tube 11 is inserted through the lid 9, and one end of the syrup extraction tube 11 hangs down from the opening 7a of the inner container 7 to a position close to its inner bottom. There is.

The lid 9 is configured to be pressed by a lid pressing mechanism 14 consisting of an arm 12 and a handle 13 for tightening, so that the opening 6a of the outer container 6 is kept in a sealed state by the lid 9. 6. The lid pressing mechanism 14 has hook portions formed at both ends of the arm 12, as shown in FIG. 12a, 12a are engaged with a bottle 15.15 protruding from the outer periphery of the upper side wall of the outer container 6, the arm 12 is hung above the lid body 9, and a tightening handle is attached to the center of the arm 12. The screw portion 13a of the handle 13 is screwed together and the lower end of the screw portion 13a is pressed against the upper surface of the lid body 9.Tightening is performed by forming an engagement groove on the upper end circumferential surface of the screw portion 13a of the handle 13. 13b is provided around the periphery, and the knock pin 16 screwed into the annular wall 9a at the center of the upper surface of the lid body 9 that receives the lower end of the threaded part 13a is engaged with the above-mentioned engagement al 3b, thereby tightening the handle 13. The lid body 9 is connected to the lid body 9.Thus, tightening can be done by turning the handle 13 in the opposite direction to that when pressing the lid body, and the handle 13 lifts the lid body 9 and opens the outer container 6. The lid 9, which is press-fitted into the lid 6a, can be easily opened.

The syrup extraction pipe 11 extending from the lid 9 to the outside of the outer container 6 is controlled to open and close by a solenoid valve (not shown) provided in the middle thereof, and the pressure of the compressed carbon dioxide gas introduced into the outer container 6 is controlled. When the solenoid valve is opened, the syrup in the inner container 7 that receives the syrup is drawn out from the syrup extraction pipe 11 in an amount corresponding to the valve opening time, diluted with water or carbonated water in the mixing mechanism, and poured into the desired amount from the supply port. It is configured to be dispensed as a concentrated soft drink.

The gas introduction pipe 10 and the syrup extraction pipe 11 are removably connected to each other by a union joint (not shown), so that opening and closing of the lid 9 with respect to the outer container 6 is possible between the gas introduction pipe 10 and the syrup extraction pipe 11. 11 so that it can be easily performed without being hindered.

In this beverage liquid supply device, when the syrup in the inner container 7 is sequentially extracted from the syrup extraction pipe 11 and the inner container 7 becomes empty or the amount of syrup remaining becomes small, first, the outer container 6 or the lid is removed. The relief pulp (not shown) attached to the outer container 6 is opened to release the pressure gas from the outer container 6, and the outer container 6 is removed.
Bring the internal pressure to atmospheric pressure. After that, the lid 9 is removed from the opening 6a of the outer container 6, the inner container 7 is taken out from inside the outer container 6, and another new inner container 7 filled with syrup is placed inside the outer container 6, By closing the opening 6a of the outer container again with the lid 9, the syrup can be replenished. Therefore, the inside of the "F-W" line 6 is not contaminated with syrup, and the trouble of cleaning the outer container 6 every time the syrup is replenished is saved.

By using the so-called one-way method in which the inner container 7 is not intended to be reused, it is possible to eliminate the need for cleaning the entire container, but after removing the inner container 7 from the outer container 6, it can be cleaned and reused. You may also use it.

[Embodiment 2] Figures 3 and 4 show an embodiment of the second invention, in which the inner container 7' for storing syrup is a contractible airtight container made of soft plastic or the like. A container is used. It should be noted that in the other configurations, the members with the same reference numerals as those in the first embodiment have the same structure, so the explanation thereof will be omitted.

In the process of manufacturing and shipping syrup, the inner container 7' is sealed by sealing the syrup injection lower a' with a thin film 17, as shown in an enlarged view in FIG. 4, after the syrup is filled. It's being measured. Also, the above syrup inlet? a'
An open cylindrical portion 7b' made of a hard material is formed around the .

On the other hand, an O-ring 18 is connected to one end of the Shironobu extraction tube 11 facing into the inner container 7'.
A stopper lid 19 that can be press-fitted is integrally formed, and as this stopper 1t9 is fitted into the opening cylindrical portion 7b' of the inner container 7', a syrup extraction hole formed in the shape of a cutting edge is formed. tube 11
One end of the syrup injection lower member a' breaks through the thin film 17 of the syrup injection lower a' and faces into the inner container 7' as shown in FIG.

In this embodiment, the inner container 7' is housed in the outer container 6 in an inverted position, that is, with the open cylinder portion 7b' facing downward, and the syrup extraction tube 1 facing into the inner container 7'
1 is bent into a hook shape so that the syrup extraction tube 11 faces into the inner container 7' from below, so that the white knob that deviates downward due to its own weight remains in the inner container 7'. The structure is such that the syrup can be extracted more efficiently than the syrup extraction tube 11. Note that, as in the first embodiment, the inner container 7'
The syrup extraction tube 11 may be exposed inside. The syrup extraction tube 11 is made of stainless steel or the like to provide sufficient strength, and as shown in FIG. 3, the inner container 7' is suspended and supported only by the syrup extraction tube 11.
For example, as shown in phantom lines in FIG.
A middle bottom plate 20 having a structure that does not hinder the vertical movement of the inner container 7' may be added to the outer container 6, and this middle bottom plate 20 may support the inner container 7'.

In the beverage liquid supply device of this embodiment, the compressed carbon dioxide gas introduced from the gas introduction pipe 10 increases the pressure inside the outer container 6, and the increased pressure causes the inner container 7' to contract and deform. syrup is pressurized. Therefore, the inner container 7'
The syrup inside is not directly exposed to the compressed carbon dioxide gas introduced into the outer container 6, and the quality of the syrup inside the inner container 7' is maintained well over a long period of time.

Incidentally, as in Example 1, the syrup in the inner container 7 is transferred to the outer container 6.
If the inner container 7' is directly exposed to the compressed gas introduced into the inner container 7', using carbon dioxide gas as the compressed gas is effective in preventing the quality of the syrup from deteriorating and improving the flavor of the carbonated beverage. In this embodiment, air may be used as the compressed gas.

Although each of the above embodiments has been described for the case where syrup is stored as a drinking liquid in the inner containers 7, 7', it goes without saying that the invention can also be applied to cases where other drinking water is supplied.
