FIG. 2 is a half sectional view showing the state in which the cylindrical seal film 11 is folded and housed in the tray 7, and FIG. 1 shows a state where one side is contracted.

As described above, the body of the container 1 is formed such that a steel or resin-made cylindrical body having a different diameter is divided into a plurality of parts in the horizontal direction, and they are fitted in the outside, inside and inside in the vertical direction. The upper part of the outer cylinder 3 and the lid 2 are connected via flanges 3a and 2a, and the lower end of the inner surface of the same outer cylinder 3 and the upper part of the outer surface of the intermediate cylinder 4 which are next to the same. Around the end, a ring-shaped or intermittent suspension mechanism 8A, 8B is provided in the circumferential direction by attaching members such as ribs or flanges or bending the plate end of the body inward or outward, or the like. When they extend, they slide upward while meshing and suspending, which are successively fitted and provided with a similar mechanism at the upper end of the outer surface and the lower end of the inner surface of the intermediate cylinder 4 arranged inside and suspended from each other. And transmitted to the suspension mechanism at the upper end of the outer surface of the inner shell 5 Promote the extension of the body. A bottom plate 6 is provided below the inner body 5 to form a tray 7. Also, a fall prevention member 9 when each body is reduced and fitted is provided on the upper part of the inner surface of each body, and the plurality of bodies are combined to be slidable, and a suspension and drop-off prevention mechanism is provided. It is formed as a container having a structure. Further, a sheet in which a polymer such as rubber or resin is laminated or impregnated inside the container, or a cylindrical sealing film
Is provided as a cylindrical body corresponding to the inner diameter of the container and the length when the container is extended, and upper and lower ends of the cylindrical sealing film 11 are provided on the lid 2 and the upper portion of the outer body 3 with the flanges 2a, 3a and the tray 7 A mounting flange 7a is provided at the upper part, and each is fixedly joined to the inside of the container with a bolt, an adhesive, or a combination thereof, and the like. In addition, the container 14 can be extended and contracted or bent to support the container.
4A is provided.

Therefore, even when the slidable container 1 is extended and the powder fluid is accommodated therein, the container body is securely suspended, and the cylindrical sealing film 11 is provided between the cylindrical bodies. The gap is completely sealed, and when the contents are discharged and the container shrinks, the cylindrical sealing film 11 is folded and stored in the lower receiving pan B so that it can be used repeatedly.

When manufacturing the container main body 1 and mounting the cylindrical sealing film, as a procedure, a suspension mechanism 8 constituting each stage of a multi-stage system is used.
A and 8B are attached to the outer cylinder 3, the intermediate cylinder 4, and the inner cylinder 5 provided with the bottom plate 6 and the receiving plate 7 are sequentially fitted from the inner cylinder. The base 12 and the nozzle 13 are attached to the lower predetermined position to form the body and the lower part. At this time, the drop prevention member 9 is continuously or intermittently attached around the upper part of the inner surface of each body. Take measures to prevent falling when sliding down. However, the seal film mounting flange 7a on the upper part of the inner body 5 may be mounted before fitting and may be formed to protrude inside. In such a state, the lower end of the separately formed cylindrical sealing film 11 is first firmly fixed to the upper flange 7a of the inner body using a contact plate 10 or the like with bolts or the like, Further, the upper end of the cylindrical sealing film 11 is fitted to the outer body flange 3a via a gasket or the like, and this is firmly fixed by sandwiching it with the lid flange 2a to form the container body incorporating the sealing film of the present invention. I do. Note that the cylindrical seal film 11 can be fixed by bonding and can be used in combination. The cylindrical sealing film 11 mounted in this way conforms to the body even when each step of the body of the main body is extended, and is easy to bend when it is reduced. A plurality of self-supporting expandable / contractible or bendable columns are provided outside the container.

When the trunks 3, 4, and 5 of the container body 1 slide down and descend to the lower part, the trunks 12 receive the trunks and the fall prevention member 9 may not be provided. is there.
In addition, since the diameter of each upper body is large in this container, it has a structure that also prevents rainwater intrusion and dust prevention measures. Furthermore,
By providing a gradient at the bottom 7 and providing the nozzle 13 at the bottom of the bottom, liquid accumulation can be eliminated.
It is also possible to design the bottom mount 12, the nozzle 13 and the like smaller than the inner diameter of the intermediate drum 4 and to mount them in advance. Further, an opening / closing lid can be provided at the bottom of the container, and a large amount of contents can be discharged while the container is suspended.

Further, as shown in FIG. 5, the upper lid 2 and the outer trunk 3
Can be directly joined without using a flange member, and the sealing film 11 can be mounted inside the container. Or, FIG.
As described above, the upper end of the sealing film 11 can be bent outside the upper flange of the container and fixed using a member.
Further, the suspension member 8B and the fall prevention member 9 can be simultaneously joined to the upper portion of the intermediate body 4 and the inner body 5 by the integral member 20 after the body portion is fitted.

The plurality of columns of the container according to the present invention can be formed in a rod-like structure such as a plug-in type with a lower portion or a one-touch bending type. In the case of a large container, it is desirable to use a jack-up type support by air, hydraulic, electric, or mechanical operation. In addition, since it is a self-supporting type in which the lid can be lifted by the internal water level by water supply from the lower nozzle, it can be used without using a column.
In the case where the liquid is discharged from the lower nozzle without using the support, there is an advantage that the air need not be vented from the lid.

Further, the container has a multi-stage sliding structure as described above, and as shown in FIG. 4, the sealing film 17 is formed into a bag-like shape having the same shape as the container provided with each supply / discharge port, and is mounted on the entire inner surface of the container. Thus, the same function and performance as described above can be provided. In this case, it is desirable to provide a suspender 18 for supporting the weight of the seal film 17.

Further, the multi-stage slide type container with a built-in seal film of the present invention can be manufactured not only in a circular shape but also in a square shape, and can be adapted according to the application and purpose, so that space efficiency can be improved. . When the container is placed on the truck as a container, it can be provided in a rectangular shape in the vehicle width direction as shown in FIG. 8 and the container can be fixed from both sides of the vehicle.

In addition, by freely selecting the material of the main body and the sealing film, the material can be used as a corrosion-resistant material container, and at the same time,
By using an inner bag in combination, it can be used for more versatile purposes. In particular, it can be used as a container for transporting refrigerated vehicles, which is particularly suitable for means such as raw milk transport that requires a high degree of control under the Food Sanitation Law.

Further, the extension of the multi-stage body of the present invention is achieved by providing the lid 2 on the upper part of the inner cylindrical body 5 and the bottom plate 6 on the lower part of the outer cylindrical body 3 so that the inner body is positioned higher when extended. It is not refused to use a slide type container having a built-in seal film as described above, but in this case, it is preferable to use it indoors or cover it with a sheet for the purpose of preventing infiltration of rainwater or dust.

Although not shown, in addition to the above, the sealing film can be attached by joining the upper end directly to the lid, and provided on the entire upper half of the lid and the body. A method in which the lower part is not applied to the lower part or a method in which the lower part is provided in the lower half part of the body part and the bottom part and not applied to the upper lid part can be implemented.

When the container of the present invention is used for transportation,
Providing a fixing bolt 19 with a contact plate at each stage of the body is effective in preventing vibration during transportation.

The small and medium-sized containers of the present invention can be handled by a forklift and can be used in combination with a pallet. Furthermore, when storing in space, it is possible to stack each other, which is very convenient for storage.

In the event that the sheet film is damaged or aged, it can be repaired or replaced depending on the degree, so that it is very economical.

According to the present invention, as described above, the body portion of the steel or resin container body is divided in the horizontal direction to form a multi-stage vertical slide system having different diameters, and a lid and a bottom plate are provided on the upper and lower sides. At the same time, a suspension and a fall-prevention mechanism are provided at the upper and lower ends of each step body, and a seal made of a sheet or polymer alone laminated or impregnated with a polymer so as to be connected to the top and bottom inside the body. A membrane is fixed and attached, or a bag is provided on the entire inner surface of the container to completely seal external leakage of the powder fluid contained in the container, and furthermore, seal when the container body is reduced after discharging the contents. Since the membrane is folded and stored in the tray and the height of the container is reduced to one third to one fourth or less, the following excellent effects are obtained. This container, whose body is made up and down of an external container and an internal sealing film structure, can be used repeatedly for a long time.
It can be used as a container for all liquids including foods other than combustibles and dangerous substances, and many powders, and can be designed to have a free capacity, so it can be used as a stationary or transport container, and in addition to a tank lorry It can also be used as a means of transportation. In particular, it is extremely easy to install as a temporary container, or exhibits outstanding power in removing or periodically moving after completion of work. It is also suitable as a container for emergency replenishment of drinking water in case of emergency for disaster prevention. In addition, since the material of the container itself or the seal film can be freely selected, it can be widely used as a corrosion-resistant material container,
It can be used as a container that can be used repeatedly over a long period of time instead of conventional oil cans, drums, or 1000 liter cans, and can save resources. Furthermore, liquid or granular material is transported in place of the tank lorry, and loading on the return flight is also possible, so that the efficiency of the transport surface can be improved and the economic efficiency can be greatly improved.
Further, even when a high level of control is required under the Food Sanitation Law such as raw milk, many advantages can be expected by using an inner bag in combination. In addition, by reducing the gap between each body cylindrical body, it can be used as a medium-low pressure vessel, so that the content liquid can be sent to a distant or high place by pressure feeding, and
The discharge speed of the content liquid can be promoted. In addition, it can be applied to gas tanks and the like due to its advanced design. Even when used as a container, no assembling work is required at all, and an operation by a break lift is also possible. Further, since the injection and discharge of the liquid can be performed by the lower nozzle, the piping device can be simplified. Furthermore, when pouring by the lower filling method, there is no bubbling of the liquid, and the lid floats on the liquid surface of the filled liquid constantly, making it impossible to form an air layer. Also, there is no generation of bubbles on the liquid surface during transportation, which can help maintain quality.
