DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag-in-box type liquid container for storing a bag filled with a liquid in a box and discharging the liquid.

[0002]

2. Description of the Related Art In a liquid dispensing apparatus for automatically dispensing beverages of various juices, a plastic film bag is used as a container for filling a liquid such as the above-mentioned beverage syrup. The liquid is filled, the bag containing the liquid is placed in a rectangular parallelepiped box made of cardboard or the like, and an outlet of the bag protruding from one end of the box and a discharging mechanism including a discharging valve of a liquid discharging device are provided. A liquid container called a bag-in-box, which is connected by a tube and sucks out the tube or pressurizes the outer peripheral surface of the bag with pressurized air to discharge the liquid in the bag, is used. It has become.

The above bag-in-box (hereinafter referred to as BIB)
Since the bag for storing the liquid (hereinafter abbreviated as) has a bag structure, when the liquid is discharged from the spout, the liquid lower than the level of the spout is not discharged, and the loss increases.

Conventionally, as shown schematically in FIG. 6, a box b of BIBa is placed in a BIB storage section (in a dispenser or in a BIB storage section separate from the dispenser) of a liquid dispensing apparatus such that a spout port c faces downward. An inclined plate d as shown in FIG. 7 is provided in such a manner as to be loaded in such a manner as to be inclined forward to the inclined position, and the inclined plate d is set in the BIB storage section of the dispensing device, and BIBa is loaded thereon. In this way, the BIBa is placed in the forward inclined posture, or the above-mentioned inclined plate is built in the BIBa (for example, Japanese Patent Laid-Open No.
No. 4567).

[0005]

However, the conventional BIB
In the case where the box b of FIG. 6A is loaded with the tilt, the virtual space when tilted in FIG. 6 is indicated by the dead spaces e, e. Occurs. For example, the volume of the box b of BIBa is about 1
When the capacity is 3 liters, the space required for the BIB storage unit is about 19 liters, and there is a problem that the use efficiency of the space for installing the BIBs is more than about 40% and wasteful.

Further, in the case where the inclined plate is formed in the box b, the space below the inclined plate becomes a dead space, and the point that the volume of the box is required to be larger than that of the bag is not improved much. There is.

According to the present invention, there is provided a BIB storage portion of a liquid dispensing device,
Another object of the present invention is to provide a bag-in-box type liquid container that does not generate a dead space in a BIB box and that can minimize the remaining amount of liquid in a bag.

[0008]

According to the present invention, there is provided a bag for storing a bag filled with liquid in a box and discharging the liquid from a spout of the bag projecting from the box. In the in-box, a bag receiving plate is provided on the inner surface of the bottom of the outer box, and an elastic body is provided on the lower surface of the bag receiving plate. When the bag is filled with liquid, the bag is opposed to the elastic body. The bag receiving plate is placed in a flat shape, and the bag receiving plate is pushed upward with the spout of the bag as a fulcrum by the elastic restoring force of the elastic body with the decrease of the liquid by the pouring. Is arranged to lean forward.

As a result, the bag can be initially filled to the full volume in the box, so that no dead space is generated in the box, and the rear portion of the bag receiving plate is gradually added as the liquid in the bag is discharged. , The amount of liquid remaining in the bag is reduced to an extremely low level, and the usage efficiency can be increased. Also, since the BIB may be loaded into the BIB storage unit in a horizontal posture, the volume of the BIB storage unit can be minimized.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes the entire BIB,
Reference numeral 2 denotes the box, in which a bag 3 filled with a liquid such as syrup is stored, and a spout 4 of the bag 3 is projected from one end of the box 2 to the outside.

The bottom 2a of the box 2 is provided on the upper surface of the bottom 2a.
A bag receiving plate 5 having substantially the same size as a is provided.

The bag receiving plate 5 is a plate made of plastic, paperboard, or the like having rigidity enough to withstand the weight of the bag 3 filled with liquid, and has an elastic body 6 on its lower surface.
Is provided.

The elastic body 6 is made of a resilient member such as a sponge as shown in FIGS. 1 to 4 or a plate made of an elastic plastic or metal material as shown in FIG. When the inside of the bag 3 is filled with liquid, the elastic body 6 bends flat by its weight, as shown in FIGS. The bag 3 has elasticity to gradually push up the rear side as the pouring proceeds. An installation position of the elastic body 6 can be appropriately selected in consideration of a repulsive force, an inclination angle, a physical property of the elastic body, and the like.

Accordingly, the bag 3 filled with liquid is placed in the box 2
When the box 2 is placed in the box 2, the bag receiving plate 5 is placed on the upper surface of the bottom 2a of the box 2, the bag 3 is stored thereon, and the spout 4 is projected out of the box 2 as before, and the box 2 is closed. This forms BIB1.

As a result, the elastic body 6 on the lower surface of the bag receiving plate 5 is compressed by the weight of the bag 3 as shown in FIGS. 1 and 3, and the back receiving plate 5 is placed in a substantially flat shape. Are housed in the entire internal volume of the box 2.

Thus, the box 2 containing the bag 3 is stored in the BIB storage section of the liquid discharging device, and is used for discharging the liquid in the bag 3.

As the liquid in the bag 3 is poured out, the rear side of the bag receiving plate 5 gradually rises due to the restoring force of the elastic body 6 crushed by the weight of the bag 3, and the bag 3
4 is pushed up so that the liquid can be poured up to the level indicated by L in FIG.

According to an experiment, in the case of a bag containing 9 to 9.5 liters, the inclination angle of the bag receiving plate 5 at the time of the highest rise is the box 2.
When the angle was set to 10 ° with respect to the bottom 2a, the remaining amount of the liquid in the bag 3 was about 1.4% of the initial liquid amount. Incidentally, when no inclination is given, the remaining amount of 6% to 7% occurs.

[0020]

As described above, according to the present invention, B
A bag receiving plate is provided on the bottom of the IB box, and an elastic body is provided on the lower surface on the rear side of the bag outlet of the bag receiving plate. Is compressed and the bag receiving plate is flattened, so that the bag can be filled to the full internal volume without changing the internal volume of the box, and the size of the box is minimized relative to the volume of the bag. The BIB storage section of the liquid dispensing device is about 4
The BIB storage space efficiency can be increased by 0%, and the BIB can be poured out in a stack.

Further, as the liquid is poured out, the rear portion of the bag is lifted, so that the bag can be poured out as much as possible, and the amount of liquid remaining in the bag can be reduced to the utmost, thereby significantly increasing the yield. it can.
