Description

[Detailed description of the invention] Storehouse! TECHNICAL FIELD The present invention relates to a back-in-box container (a plastic bag is placed in a box made of paperboard or cardboard) for storing liquids, particularly highly viscous liquids.

A conventional box-bag container of this type is constructed as shown in FIG. In FIG. 5, a box 1 made of paperboard or cardboard has a plastic bag 2 inserted therein, and an opening 3 of the bag 2 protrudes from the side of the box 1.
This bag 2 contains a highly viscous liquid 4 (for example, printing press ink).

Problems that Ming attempts to solve: A boxed container constructed in this way is set in a printing machine with the side of the box body 1 with the opening 3 facing the side or the bottom.
If the inner diameter of the opening 3 is small, the liquid 4 with high viscosity will be transferred to the bag 2.
It takes time to take it out, and if the diameter of the opening 3 is increased, the liquid will spill out when the box 1 is folded down when the cap is removed from the opening 3 and set in a printing press.

In order to solve this problem, devices and automatic bottle openers are known in which a seal is pasted on the mouth portion 3 so that the seal can be torn when the bottle is set, but these devices have the drawback of high cost.

There is also known a device in which the box 1 is set in a printing press and the opening 3 is connected to a suction pump to suck out a liquid 4 such as ink, but in this case.

As shown in FIG. 6, even though the liquid 4 remains below the bag 2, a part of the bag 2 blocks the mouth 3, making it impossible to aspirate the liquid 4. .

In order to solve the above-mentioned drawbacks, the present invention is to place a bag container made of plastic film in a box made of paperboard or cardboard, etc., and to open the cylindrical opening of the bag container. A boxed bag container in which a liquid is protruded from an opening of the box body, and a guide for guiding the liquid is inserted into the opening.

In the present invention, when setting the spout in the printing machine after removing the spout cap, liquid does not come out even if the spout is placed downward for a short period of time, and by removing the dielectric from the spout, it is possible to prevent liquid from flowing during filling. The diameter of the mouth is made larger, the filling time is shortened, and the mouth is not blocked by a part of the bag when sucking the liquid, so that the liquid is sucked so that the suction does not become impossible midway through. .

Lost Garden Masu, Figure 1 shows a cross-sectional view of a boxed bag container according to an embodiment of the present invention. Then insert the cylindrical guide member 5. The outer diameter of the inductor 5 is almost equal to the inner diameter of the mouth portion 3, and the inner diameter is small, and a large number of holes 6 are provided in the side surface of the inductor 5.

In the boxed bag container of this embodiment configured in this way, when dispensing the liquid 4, the cap is removed from the opening 3 and the opening 3 is removed.
It is set in the printing press with the opening facing down, but at this time, since the inner diameter of the opening 3 is smaller than the inside diameter of the dielectric 5, the viscous liquid 4 will not fall even if the opening 3 is turned down for a short time. and,
After setting the boxed bag container in the printing machine, the pump receiver of the printing machine is brought into close contact with the mouth part 3, and the pump suctions the liquid 4, as shown in Fig. 2. Even if the film 2 closes the end 5' of the dielectric 5, the film of the bag 2 has stiffness, so it wrinkles, which creates resistance and prevents the bag 2 from closing.
Since the peaks and valleys are formed, all of the many holes 6 on the side surface of the dielectric 5 are not all blocked by the bag 2, and the liquid 4 is sucked from any of the holes 6.

Note that the dielectric 5 is not limited to one having a large number of holes 6 on the side surface of the cylinder as shown in FIG. 3(a) above, but also has elongated holes 6 on the side surface of the cylinder as shown in FIG. 7, or as shown in FIG. 3(c), a cross-shaped inductor 5b may be connected to a short cylinder 5a.

Tsunryu father-in-law? - Figure 4 shows a cross-sectional view of a boxed bag container according to another embodiment of the present invention, in which an appropriate taper is provided on the inside of the opening 5C of the inductor 5, and the pump receiver is connected to the taper of the part 8. When combined with 88, there is an advantage that adhesion is improved and pump suction becomes easier.

As is clear from the above explanation, in the present invention, by fitting and inserting the derivative into the first mouth part, no liquid will come out even if the cap of the first mouth part is removed and the mouth part is turned downward. The liquid does not spill when setting it on the printing machine, and since the dielectric is removed when putting the liquid into the bag, viscous liquid can be put in in a short time.Furthermore, when suctioning, since the dielectric is present This has the advantage that the mouth part is not blocked by the bag and most of the liquid inside the bag can be sucked out.
