Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for selling beverages such as juices, alcoholic beverages, soft drinks, and seasonings such as soy sauce and sauces in large quantities using cardboard or other decorative boxes. This relates to liquid containers used for

[Prior art] Containers for selling beverages such as milk and alcoholic beverages have traditionally been made of cardboard or other decorative boxes, coated with synthetic resin on the inside, or with bags made of synthetic resin placed inside. There are also known containers that are equipped with spouts made of simple synthetic resin.

[Problems with the prior art] However, although conventional containers of this type are sufficient to store items that are unlikely to deteriorate, such as seasonings and juices, they do not allow air to enter or gas to leak out. The sealing properties are not good enough to prevent this, especially for beer, cola, etc., which require sealing properties.
There was a problem in that it was not suitable for storing or selling sparkling beverages such as cider or high-quality wines that were particularly sensitive to oxidation. However, in order to improve the sealing performance and make it possible to store these beverages, there is the problem that the structure of the container, such as the spout, becomes complicated, which increases manufacturing costs and makes the container unsuitable for manufacturing and selling in large quantities. Ta. In addition, conventional containers with a spout that protrudes from the side or top of the container have an irregular overall shape, making it inconvenient to stack, transport, or sell in large quantities.

Although the present invention has an extremely simple structure, it has good airtightness and enables long-term storage of liquids such as all kinds of beverages, including beer and wine, and can be stacked in a compact shape when being transported or sold. The present invention provides a liquid container that can be transported and sold in large quantities with little risk of breakage.

[Means for Solving the Problems] As described in the claims, the present invention accommodates a non-ventilated airtight bag in a presentation box made of a material such as cardboard or synthetic resin, and A fixed cylinder having a communication port with the inside of the bag and one end of which is attached to the inner surface of the cosmetic case directly or through a member and whose interior is a liquid passage, and the fixed cylinder is screwed into the fixed cylinder and rotated. a movable tube whose interior is a liquid passage that moves in the axial direction of the fixed tube; a first valve located at one end of the movable tube and opened and closed by movement of the movable tube; and a first valve located at the other end of the movable tube. and a second valve having an injection outlet, the double valve spout having a structure in which the first valve is opened by rotating a movable cylinder and the spout is projected outside the cosmetic case. The first valve is tightly closed when the fixed cylinder and the movable cylinder are sealed by the relative movement of the fixed cylinder and the movable cylinder, and the spout opening is housed in the cosmetic case, and the first valve is opened when the cylinder is opened. A movable cylinder having a pouring port and a pouring port protrudes outside the cosmetic case, and liquid can be poured in and out by operating a second valve. Because of this double-valve structure, the container is highly airtight, and the spout is housed inside the cosmetic case when the container is closed.

[Embodiment] Fig. 1 is a partial sectional view of one embodiment of the present invention, in which 1 is a decorative box made of cardboard, 2 is an airtight bag made of a plastic sheet, and 3 is a fixed tube with a seal at one end. A tubular projection 13 with a passage 8 with the bag 2 is provided. An annular member 11 having a screw-shaped protrusion 12 inside is fitted to the other end of the fixed cylinder 3.
The screw-like protrusion 12 is screwed into a groove 7 threaded on the surface of the movable cylinder 4, and thereby the movable cylinder 4
can be moved from side to side in the figure by rotating it around its axis. Of course, the screwing of the movable tube and the fixed tube is not limited to the above-mentioned embodiment, and may be of any configuration, for example, by threading the movable tube and the fixed tube, respectively. The right end 14 of the movable cylinder 4 in the figure and the tubular projection 13 constitute a first valve, and when the valve is closed, the end 14 closes the passage 8 in the tubular projection 13 as shown in FIG. When opening, the passage 8 is opened by rotating the movable cylinder 4 about its axis and moving it to the left in the figure. Reference numeral 10 denotes a ring-shaped seal member that is provided as necessary to completely seal the first valve, but it may be omitted depending on the materials of the movable cylinder 4 and fixed cylinder 3, etc.
A second valve consisting of a second valve cylinder 15 and a cock 5 is formed at the other end of the movable cylinder 4. The pot 5 is located so as to intersect with the axial direction of the second valve cylinder 15 and closes the spout port 6. When opening the valve, the second valve is opened by rotating the pot 5 and aligning the axis of the hole 16 with the axial direction of the second valve cylinder 15.
A liquid passageway is formed leading to the valve.

The second valve cylinder 15 is not limited to a separate member from the movable cylinder 4, and may be formed integrally with the movable cylinder 4.

In the liquid sales container of the above embodiment, when filling liquid, the movable cylinder 4 is rotated around its axis and moved to the left in the figure to open the first valve and at the same time, the second valve cylinder is projected from the cosmetic case 1. By rotating the pot 5 to open the second valve, applying a nozzle from a high-speed filling machine to the pouring inlet 6 and injecting the liquid, the sealed bag 2 can be filled with liquid without resistance.

When filling the container with liquid using a high-speed filling machine, the spacer 9 resists the pressure of the filling machine and prevents the container from being deformed or damaged. This spacer 9 may have any shape, for example, it may be an extension of the fixed cylinder as it is, or it may have a structure in which a simple protrusion is provided. Further, depending on the type of filling machine, it may not be on the axial extension of the fixed cylinder 3, and may support the side surface of the fixed cylinder 3.

When transporting and storing, rotate Kotoku 5, close the second valve, rotate the movable cylinder around its axis, and open the first valve.
By closing the valve, the seal is completely sealed, and the spout 6 is housed in the cosmetic case, so it does not take up much space, is sanitary, and is extremely convenient for transportation and storage. To take out the liquid, open the valve in the same manner as when filling.

The container of the present invention is not limited to the embodiments described above, and as long as the first valve is closed and opened by the movement of the movable cylinder and the fixed cylinder, as described in the claims. As for the second valve, for example, as shown in FIG. 2, FIG. 3, and FIG. Any configuration that closes and opens the second valve may be used. In Fig. 2, reference numeral 4 denotes a movable cylinder, 20 a cylinder, and 21 a hole provided in one side of the cylinder.The valve is opened by rotating the cylinder 20 and aligning the hole 21 with the liquid passage inside the cylinder. . In Fig. 3, 4 is a movable tube, 23 is a pot, 24 is a hole in a part of the pot, 2
Reference numeral 5 denotes a hole in a part of the movable cylinder 4, and the hole 23 is rotated to align the hole 24 and the hole 25 to open the valve. In FIG. 4, 26 is a pot, 27 is a hole provided in a part of the pot, and 28 is a hole provided in the movable cylinder 4. The holes 27 and 28 are brought into alignment to open the valve.

[Effects of the Invention] Due to the structure described above, the liquid container of the present invention has a simple structure, is economical, and has good sealing properties, so it can be used to store foaming liquids that are difficult to enclose in conventional cardboard disposable containers. It is possible to seal and preserve even liquids that are highly sensitive to air infiltration, and is suitable for manufacturing and selling in large quantities. Further, when the user uses the container, the container can be resealed by closing the valve. The spout is housed inside the container and can be made into a neat box shape without unnecessary protrusions, so it has many advantages such as being able to stack large quantities quickly during transportation and storage.
