Description

Method of assembling bag of liquid container and liquid container

〔Technical field〕

The present invention relates to a method for assembling a bag of a liquid container used for transporting various chemicals, liquid foods, and other liquids, and a liquid container.

[Background technology]

Conventionally, metal or plastic tanks have been commonly used as containers for storing and transporting liquids such as various chemicals and liquid foods or beverages and liquid paints, but this kind of tank is quite expensive In addition, the efficiency of transporting and storing empty containers when returning them from the destination was inferior, and cleaning for repeated use, especially cleaning of discharge pipes with valves, was extremely troublesome. Therefore, in recent years, a bag made of a synthetic resin film or the like has been used in combination with a rigid outer frame, and this bag has been discarded in a single use, thereby simplifying the cleaning process. There has been proposed a liquid container capable of smoothly discharging to the end (for example, Japanese Patent Application Laid-Open No. H8-3373288). .

By the way, the liquid container disclosed in the above-mentioned document includes a bottom receiver for receiving a bag for a container on a pallet body, and has an opening at a center of a funnel-shaped bottom of the bottom receiver. A locking portion is provided on a lower surface of an opening peripheral portion of the bottom so that a mounting flange provided at an end of the discharge pipe with a valve can be fitted and locked from the side. The discharge pipe with pulp is detachably attached by the engagement of the flange. In the bag, the cylindrical portion of the outlet member attached to the bottom of the bag is fitted into the inside of the end of the discharge tube. And the connection is made.

In the case of this liquid container, even when working below the bottom receiver, the discharge pipe with the valve can be incorporated and set relatively easily, but on the other hand, the discharge pipe and the bottom member of the bag body bottom part Since the connection with the shaft is simply made by inserting in the axial direction, even if a packing such as an O-ring is interposed in the sliding contact portion by this fitting, the sealing performance of the sliding contact portion is not sufficiently satisfactory. However, there is a risk of leakage due to hydraulic pressure, and this may cause anxiety to the user, especially when the contents are dangerous substances such as chemicals.

In addition, when returning the one-way bag from the outer frame or when removing the drain pipe with a valve at the time of return from the destination, it is necessary to pull out the mouth member at the bottom of the bag from the drain pipe. At the time of removal, the residual liquid in the bag body may drip from the member, and the floor surface may be soiled. The present invention has been made in view of the above, and can easily perform an assembling set operation such as a container bag and a discharge pipe with a valve, and furthermore, a connection part between a mouth member at the bottom of the bag and the discharge pipe. It provides a built-in method and a liquid container that can be easily and safely operated without having to worry about leakage of liquid, etc., with high sealing performance, and without having to worry about drip of residual liquid when taking out the bag. I am trying to do it.

[Disclosure of the Invention]

A method for assembling a bag or the like of a liquid container according to the present invention, which solves the above-mentioned problems, comprises: a container bag having a bottom having a mouth member for a discharge port attached thereto; In a liquid container comprising a pipe and an outer frame having a bottom receiving portion for receiving a bottom portion of the container bag, when the container bag is assembled into the outer frame and set, A discharge pipe with a valve is fastened to the mouth member at the bottom of the body. And through the opening in the bottom receiving portion, the fixing member is taken out below the bottom receiving portion, and the mouth member is fixed so as to be supported by a peripheral portion of the opening.

The work can be performed easily and efficiently, and the sealing property at the connection between the mouth member and the discharge pipe can be maintained well.

Also when the bag is taken out from the outer frame, the discharge pipe can be pulled out upward from the opening in the opposite direction, so that the take-out and disassembly work can be easily performed. Further, fastening and separation of the discharge pipe with respect to the b member can be easily performed outside the outer frame. In addition, especially when the discharge pipe is separated from the mouth member, even if liquid remains inside the bag body, since the work is performed outside the outer frame, the residual liquid drip from the member. It is also possible to separate them easily without any work, making the work easier.

Further, the liquid container of the present invention includes a container bag having a mouth member for a discharge port at a bottom portion, a discharge pipe with a valve fastened to the mouth member, and a bottom portion of the container bag member. A liquid container comprising an outer frame having a bottom receiving portion, wherein the lower portion of the container bag body has a tubular portion for fastening to a discharge pipe with a valve; and the tubular portion. And a flange portion connected to one end of the outer frame.

A bottom plate having a funnel shape inclined at a center thereof, and an opening through which a discharge pipe with a valve fastened to the cylindrical portion of the mouth member can be inserted at a central portion thereof. The flange portion of the member is supported by the periphery of the opening.

Thereby, the work of assembling and taking out and disassembling the container bag and the discharge pipe can be easily performed.

On the peripheral edge of the opening of the bottom receiving portion, loosely fits on the outer periphery of the cylindrical portion of the mouth member or It is preferable to provide a receiving plate for supporting the flange portion in a fitted state so as to be freely set. Thereby, even if the opening of the bottom receiving portion has a relatively large opening so that the discharge pipe can pass through, the mouth member is reliably and stably held on the peripheral edge of the opening by the receiving plate. In addition, the work of setting the receiving plate can be easily performed simultaneously with the work of setting the discharge pipe.

In particular, in a state where the receiving plate has a split shape and the discharge pipe is passed through the opening, the receiving plate is fitted to an outer periphery of a cylindrical portion of the mouth member, and an opening peripheral portion of the bottom receiving portion. More preferably, the discharge pipe is fitted on the outer periphery of the cylindrical portion of the mouth member while the discharge pipe is passed through the opening, and is set on the peripheral edge of the opening. Can be easily performed without any problem, and the above-mentioned setting work is further easily performed.

In the liquid container, it is preferable that the end of the cylindrical portion of the mouth member and the end of the discharge pipe with a valve are liquid-tightly fastened by a clamp-type fastening structure.

As the clamp-type fastening structure, a convex edge is provided on the outer periphery of the end of the cylindrical portion of the mouth member and on the outer periphery of the end of the discharge pipe, the side surfaces of the side opposite to the opposing side forming an inclined surface. And a clamp member having a tapered surface on the inner periphery capable of being fitted to the outer periphery of the two convex edges and tightening the two convex edges in the proximal direction, and by tightening the clamp member, It is preferable that the end portion and the end portion of the discharge pipe have a structure that can be liquid-tightly fastened by interposing a packing means therebetween. Thereby, the end of the mouth member and the end of the discharge pipe can be easily and securely fastened with good sealing, and a connection state free from liquid leakage or the like can be obtained.

The mouth member is integrally formed of a synthetic resin, and a circumferential annular annular ridge for packing is provided on the end surface of the cylindrical portion of the member facing the discharge pipe. The top of the ridge on the end face of the discharge pipe facing this May be provided with a circumferential concave streak for fitting. Also in this case, the end of the mouth member and the end of the discharge pipe can be easily and securely fastened, and a connection state free from liquid leakage or the like can be obtained.

In order to assemble, the valve-equipped discharge pipe 3 is fastened to the discharge port B member 2 at the bottom of the bag 1 outside the outer frame 5 in advance, that is, before the assembly is started. As shown in FIG. 4, for example, this fastening operation is performed by connecting the end of the cylindrical portion 21 of the mouth member 2 and the end of the discharge pipe 3 to the concave grooves 23 b, A ring-shaped packing 4a such as a ring or the like is fitted to 33b so as to be fitted and sandwiched, and in this state, a clamp member is provided for the annular projections 23, 33 provided on the outer periphery of both ends. 7 and the clamp member 7 is tightened with the screw member 7 4, and the clamp members 7 are tightened in the direction close to each other by using the inclined surfaces 2 3 a, 3 3 a of the both convex edges 23, 33. As a result, both ends are liquid-tightly fastened via the packing 4a. This fastening operation can be easily performed in a wide place outside the outer frame 5.

Then, the container bag body 1 is placed inside the outer frame 5 with at least one of the four side plates 8 a, 8 b, 8 c, 8 d, for example, the front side plate 8 a opened. As shown in FIG. 9, the discharge pipe 3 is passed through an opening 52 having a central portion of the bottom receiving portion 50 from the inside downward, and is pulled out below the bottom receiving portion 50. At the same time, inside the bottom receiving portion 50 of the outer frame 5, the half bodies 55 a and 55 b of the split receiving plate 55 are attached to the lower member 2 to which the discharge pipe 3 is fastened. Under the flange portion 22 of the cylindrical portion 21 and fit the notches 56a, 56b at the divided ends of the two halves 55a, 55b to the outer periphery of the cylindrical portion 21. Then, the two halves 55 a and 55 b are abutted against each other, and set in this state on the opening peripheral portion 53 in the central region 51 a of the bottom plate 51. The flange part 22 of the member 2 is supported.

When the receiving plate 55 made of one plate material is used, the receiving plate 55 is fitted to the outer periphery of the cylindrical portion 21 of the member 2 before the discharge pipe 3 with the valve is connected. Then, after connecting the discharge pipe 3 to the cylindrical portion 21, similarly to the above, pull out the discharge pipe 3 downward from the inside as shown in FIG. 12, and as shown in FIG. The receiving plate 55 is set on the peripheral edge 53 of the opening, and the flange 22 of the member 2 is supported.
