Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible container for transporting a liquid having a specific structure made of a rubberized cloth or the like for transporting a liquid by enclosing the liquid, a method for cleaning the container, and a cleaning facility therefor.

[0002]

2. Description of the Related Art Conventionally, when a specific liquid is transported by a liquid transport vehicle equipped with a tank, for example, a specific liquid can be stored and transported on an outward route, and another liquid can be stored and transported on a return route. In this case, there is no particular inconvenience, but when the liquid is not transported on the return path, the return trip is performed in an empty state, which is not very efficient in terms of economy.

In order to solve such a problem, Japanese Patent Laid-Open No.
In Japanese Patent Application Laid-Open No. 275485/1993 and Japanese Utility Model Application Laid-Open No. 5-13993, on the outward route, liquid is enclosed in a foldable flexible container and transported to the destination, and the liquid enclosed in the destination is transferred to another container. After swapping, a flexible container for liquid transport is disclosed, which folds the flexible container and allows the vehicle to carry another normal load and transport the return path. Each of these containers has an inlet / drainage port.

[0004] When a flexible container is loaded in a container and transported in a state where the liquid is sealed, the flexible container is less moved especially when the vehicle is running at a constant speed without acceleration / deceleration. Although the deformation of the liquid is small, when the vehicle is braked, started, or accelerated, the inertia causes the liquid to move in the front-rear direction of the vehicle and locally swell above the flexible container for transport, thereby increasing the flexibility for transport. Due to the repeated occurrence of local distortion in the container, not only the durability is reduced, but also the movement of the liquid due to the inertial force during braking is large. Becomes larger than at the time of other acceleration / deceleration, and a shocking load acts on the driver every time braking is performed, which may hinder subsequent driving.

[0005] The proposal in the above-mentioned publication is to adopt a structure for minimizing deformation of the flexible container due to liquid movement as much as possible in order to eliminate the above-mentioned reduction in durability of the flexible container and discomfort to the driver. For example, Japanese Patent Laid-Open No. 3-2
In JP-A-75485, the material up to the front quarter position of the container, which is most liable to be deformed at the time of braking, in particular, the Young's modulus of the upper base material is set to be larger than other parts to reinforce the material. In Japanese Utility Model Laid-Open No. 5-13993, a band is fixed to a peripheral surface having a height of 1/2 or less from the bottom of a flexible cylindrical container, or a core reinforcing layer and a high elastic body are laminated and integrated. To increase rigidity.

[0006]

As described above, if it is possible to eliminate the deterioration of the durability of the flexible container and the discomfort to the driver, the advantage of the transportation by such a flexible container as described above. In recent years, even in the beverage and edible oil industries, attention has been focused on transportation using these flexible containers, and fresh milk and various juices are particularly enclosed in the containers and consumed from the production area. If the transportation to the ground is possible, as described above, the improvement of transportation efficiency will make it possible to obtain sufficient profit economically even in consideration of the price of the container. However, freshness of this type of edible liquid is important, and there are great restrictions in terms of food hygiene.

That is, if the liquid transported by such a flexible container is an edible liquid or beverage, the inside of the container must be constantly cleaned and hygienically controlled. Therefore, after the above-mentioned flexible container has been transported, it is necessary to perform liquid treatments such as washing, sterilization, and disinfection treatments. In order to facilitate such treatments, for example, US Pat. , 953, 1 m ³
An airtight waterproof slide fastener having a length of 5 cm is attached in the longitudinal direction at the center of the upper surface of a horizontally long cubic flexible container having a liquid storage capacity, and the portion can be opened and closed.

However, the above-mentioned US Pat. No. 3,965,9
Just like the flexible container disclosed in the specification of JP-A-53-53, a small-sized slit-shaped opening formed at the center of the upper surface of the container so as to be openable and closable by an airtight and waterproof slide fastener only cleans and sterilizes the inside of the container. If the disinfection treatment is to be performed without fail, not only is it extremely time-consuming, but also there remains such a problem that the subsequent drying treatment requires a long time. Further, when an airtight waterproof slide fastener is attached to the upper surface of the flexible container as in the flexible container disclosed in U.S. Pat. No. 3,965,953, the flexibility generated during transportation is reduced. A large stress is repeatedly applied to the airtight and waterproof slide fastener due to repeated bulging of the watertight container, and the airtight and waterproof property is reduced, leading to the occurrence of liquid leakage. Further, needless to say, the flexible containers disclosed in the above-mentioned publications, none of the flexible containers disclosed in the above-mentioned U.S. Pat. Even if the cleaning is performed, there is no guarantee that the inside of the container is surely cleaned because it cannot be visually confirmed.

On the other hand, the present inventors have previously described Japanese Patent Application Nos.
No. 7709 has proposed a flexible container for transporting liquid having a structure that can be largely expanded as required, and has a structure that is unlikely to leak even when repeatedly transported. The structure is a flexible container for transporting liquid having a top surface, a bottom surface, and a peripheral surface connecting the top surface and the bottom surface, and an airtight waterproof slide fastener can be opened and closed on the peripheral surface. And the mounting height h of the slide fastener from the bottom surface is less than or equal to の of the total height H.

The present invention has been made by paying attention to the characteristic structure of the earlier application filed by the present inventors, and enables more efficient cleaning, sterilization / disinfection processing and drying processing, and at the same time, has the required durability. It is an object of the present invention to provide a flexible container for transporting a liquid, which secures airtightness and airtight waterproofness, and a method and equipment for cleaning the container.

[0011]

Means for Solving the Problems and Effects of the Invention The present inventors have succeeded in achieving the above object following the earlier application by improving the structure of each part of the container to achieve efficient cleaning, sterilization and disinfection. It was thought that a container capable of performing processing and the like, securing required strength, and having no liquid leakage could be obtained. Since the invention of the flexible container according to the earlier application employs a structure in which most of the inner surface of the container can be visually observed from the outside at least after washing, if the structure is effectively used, the above-described treatment with a liquid is performed. It was also concluded that drying could be effected in a short time and effectively.

The previously proposed flexible container for transporting liquids comprises:
It is made of an airtight waterproof sheet material, and has a top surface, a bottom surface, and a peripheral surface connecting the top surface and the bottom surface.A liquid stirring port is formed on the top surface, and the top surface has a liquid stirring port. An openable and closable liquid discharge port is formed near the bottom surface, and an airtight waterproof slide fastener is attached to the peripheral surface except for a part of the non-openable / closable part.

[0013] With this configuration, the liquid agitating port and the pouring / discharging port are effectively used for cleaning the flexible container, and at least two places on the peripheral edge of the top surface are located above the container when transporting the liquid. And a suspension bar attached to a support bar (wave-dissipating bar) installed on the vehicle to suspend the container, and at least a peripheral edge of the bottom surface to fix the bottom surface to the vehicle floor surface when transporting the liquid. We considered to make effective use of the bottom surface fixing pieces attached at two places. Furthermore, it has been found that it is advantageous for the liquid stirring port to have a deaeration means according to the pressure in the container in order to perform effective cleaning.

That is, the invention according to claim 1 of the present invention comprises an airtight waterproof sheet material, and has a top surface, a bottom surface, and a peripheral surface connecting the top surface and the bottom surface. Is formed with a liquid agitating port, and an openable and closable liquid discharge port is formed near the bottom surface of the peripheral surface, and an airtight waterproof slide fastener is attached to the peripheral surface except for a part of the non-opening / closing part. A flexible container for transporting liquid, comprising: a container hanging piece at at least two places of a peripheral edge of the top face part; and a bottom part fixing piece at at least two places of a peripheral edge of the bottom face part. Preferably, the liquid stirring port has a degassing means corresponding to the internal pressure.

The waterproof tape constituting the fastener stringer used in the present invention is obtained by coating or laminating synthetic rubber, polyvinyl chloride resin, polyurethane resin, or the like on a base fabric woven by warps and wefts. It is a tape provided with waterproofness and elasticity. On the other hand, various metals are used for the teeth and the slider.

With this configuration, as in the invention according to claim 6, the airtight waterproof slide fastener is closed in an empty container state, the container is adjusted to an expanded state, and the liquid stirring port is opened. Injecting the cleaning liquid toward the inner wall of the flexible container through the stirring port, and discharging the residue adhering to the inner wall and the residual liquid in the container together with the cleaning liquid to the outside of the container through the above-described injection / drain port. And a method for cleaning a flexible container for transporting liquid.

[0017] Here, the condition of the container means that, when the inside of the flexible container which is in a deflated state after discharging the transport liquid is washed, the container is filled with the liquid and has the same wrinkle-free form as when it is swollen. To do. As means for adjusting the volume, it is preferable to blow air into the inside of the flexible container as in the invention described in claim 9, and the blowing of air is described in claim 10. As in the present invention, the liquid supply / discharge port, which is a liquid supply / discharge port for transportation, is used.

Further, as another means for arranging the container, the container may be pulled up and stretched at a plurality of locations in the container as in the invention of claim 11. Moreover,
This stretching can be carried out by using the container hanging piece and the bottom surface fixing piece attached to the container of the present invention for fixing the container during liquid transport. That is, for example, the container hanging piece is suspended and supported by a support bar installed above a container in a vehicle or a washing facility, and the bottom fixing piece is tension-fixed to the floor of the vehicle or the washing facility, thereby providing flexibility. The wrinkle-free three-dimensional form similar to that when the sexual container is filled with liquid can be obtained. Of course, in this state, air can be further blown into the container as described above.

The washing of the container is performed as described above, with the airtight waterproof slide fastener on the peripheral surface being closed, and using the stirring port for the transport liquid attached to the top surface, For example, hoses are inserted into the container through the stirring port, and the cleaning liquid is sprayed toward the inner wall of the container under a predetermined pressure. Injection at this time may be a mere ordinary nozzle, but as described in claim 12, when the injection is performed using an injection nozzle that radially injects a cleaning liquid or the like, the inner wall of the container is uniformly cleaned, and the cleaning time is reduced. This is preferable because it can shorten the time. It is more preferable to simultaneously discharge the cleaning liquid to the outside of the container at the time of this cleaning because the residue and the residual liquid adhering to the inner wall surface of the container and the cleaning liquid can be effectively discharged. Further, at the time of spraying the cleaning liquid,
If the cleaning liquid is sprayed toward the inner wall of the flexible container and air is blown from the liquid agitating port at the same time as described in, the cleaning liquid can be positively discharged out of the container by the same air pressure, and the cleaning can be performed. The container does not shrink and wrinkles do not occur.

According to a fourteenth aspect of the present invention, the processing liquid such as the cleaning liquid is discharged to the outside of the container by using the inlet / outlet of the transport liquid of the container. The bottom of the flexible container, which is opposite to the liquid inlet / drain port, is raised to tilt the container, thereby facilitating discharge of the cleaning liquid and the like to the outside of the container.

The invention according to claims 15 and 16 defines the cleaning solution and the sterilizing / disinfecting solution, wherein the cleaning solution uses warm water of 40 to 70 ° C., and the sterilizing / disinfecting solution has a concentration of 300 ppm or less. An aqueous solution of sodium hypochlorite is used.

The flexible container for transporting liquids can transport not only drinking liquids such as milk and juice but also edible oils, for example. Therefore, in the invention according to claim 2, the constituent members of the container are made to be flame-retardant to ensure safety against fire. In order to impart flame retardancy, for example, a fire-resistant material is used for the material of the container constituent sheet and the material of the airtight waterproof slide fastener, and the surfaces thereof are plated with metal. Or, add an appropriate flame retardant to those materials.

According to a third aspect of the present invention, there is provided an air venting means according to the first aspect, wherein the liquid stirring port has an airtight waterproof slide fastener for opening and closing the stirring port. The above-mentioned air-extraction means of the stirring port utilizes the same airtight and waterproof slide fastener, and adjusts the amount of air evacuation by the degree of opening and closing of the same airtight and waterproof slide fastener. In the invention according to the tenth aspect, in the case where the volume adjustment of the flexible container is performed by blowing air from the filling / discharging port, if the amount of air blown is excessive, the container is damaged by expansion. there is a possibility. Therefore, in the present invention, the airtight and waterproof slide fastener attached to the liquid agitating port is opened as necessary to release the air in the container to the outside.

[0024] In addition, if this kind of flexible container transports the internal transport liquid to the destination and discharges it, then folds it and returns to the destination, mold is easily generated in the residual liquid in the container. This is not only not only complicated but also unfavorable in terms of hygiene. Therefore, it is desirable to perform temporary cleaning immediately after transporting the internal transport liquid to the destination and transferring it to another container, as a pre-process for performing subsequent main cleaning.

According to a twenty-third aspect of the present invention, before the main cleaning and after discharging the transport liquid, the flexible container after discharging the transport liquid is adjusted to a swollen state without wrinkles, and The above washing liquid is injected from the liquid port. At this time, the air in the container is discharged together with the increase in the amount of the cleaning liquid through the degassing means of the liquid stirring port, and after the amount of the cleaning liquid reaches a predetermined filling amount, the cleaning liquid is transported. The temporary cleaning is performed by discharging the liquid together with the remaining liquid to the outside through the inlet / drain port. In addition, other examples of the degassing means include a pressure relief valve. If the air in the container is not evacuated during the temporary cleaning, the internal pressure of the container will be too high, and the airtight waterproof slide fastener attached to the container and the peripheral surface may be damaged.

According to a fourth aspect of the present invention, the mounting height of the airtight waterproof slide fastener for opening and closing the peripheral surface portion from the bottom surface portion can be flexibly set when starting or braking while the vehicle is running as in the previous application. Stipulates that the distribution of stress acting on the watertight container is 1/10 to 1/2 of the total height of the container, so that excessive stress during transportation does not act on the airtight waterproof slide fastener to improve durability. ing.

As described in the earlier application, according to many experiments, the behavior of the liquid in the flexible container due to acceleration and deceleration at the time of starting or braking during transportation is almost half as high as the liquid level. It has been found that the cradle moves back and forth greatly, and that the depth of movement is extremely small at a depth greater than that. In other words, the liquid in the container moves the largest near the front surface of the top surface, and the amount of movement gradually decreases as the depth increases, and almost no movement occurs when the depth becomes deeper than half the depth of the container.
When the amount of movement changes in this manner, the stress acting on the front or rear surface of the container also changes, and the amount of expansion of the flexible container also depends on the amount of change.

According to a fifth aspect of the present invention, the form of the container for securing reliable washing and ease of washing, the method of attaching the airtight waterproof slide fastener, and the attaching positions of both ends thereof are specified. ing. That is, the container is a horizontally long cubic container in which the peripheral surface portion includes a front surface portion, a rear surface portion, and first and second side surfaces, and the airtight waterproof slide fastener includes the front surface portion and the rear surface portion. And the non-opening / closing portion is arranged on the other surface portion except the front surface portion, while being continuously attached over three of the first and second side surface portions.

According to a cleaning method described in claim 17, which is different from the cleaning method described in claim 6,
To expand and clean the flexible container of the present invention,
The mounting position of the airtight and waterproof slide fastener attached to the peripheral surface of the horizontally long cubic container is preferably three positions on the peripheral surface. However, in such a horizontally elongated cubic container, the stress on the container due to the movement of the liquid during braking of the vehicle during liquid transportation, especially when sudden braking is applied without stopping, is the largest. It is the front part of the surface part. On the other hand, in the hermetically sealed waterproof slide fastener in the closed state, the portions most susceptible to the instantaneously acting stress are the upper and lower stopper portions arranged at both ends of the non-opening / closing portion. is there. Therefore, in the present invention, the top stop and the bottom stop which are most susceptible to the stress of the hermetic waterproof slide fastener are attached so as to avoid the front portion of the container where the stress is applied most.

The invention according to claim 7 specifies that after the completion of the above-mentioned cleaning according to claim 6, finish cleaning for sterilization and disinfection is performed. In other words, in the present invention, after discharging the cleaning liquid according to claim 6, the sterilizing / disinfecting liquid is jetted toward the inner wall of the flexible container through the liquid stirring port, and the sterilizing / disinfecting liquid is discharged and discharged. This includes draining out of the container through the liquid port. Usually, the residual liquid in the container is washed away after the final cleaning with the sterilizing / disinfecting liquid. The invention according to claim 8 defines a method for washing away. That is, after the sterilizing / disinfecting liquid is discharged, water is further injected through the liquid stirring port, and the water is discharged out of the container through the injection / draining port.

The invention according to claim 17 is a method of cleaning a flexible container having the above-mentioned configuration different from the invention of the cleaning method according to claim 6, wherein the method of cleaning the flexible container after discharging the transport liquid. Opening the airtight waterproof slide fastener, opening and closing the container with the slide fastener opened, with the top and bottom portions of the flexible container being separated from each other with the non-opening / closing portion as a base, and the inner surface of the container. Exposed to the outside, pre-cleaning the flexible container with the inner surface exposed with a cleaning liquid,
And finish-cleaning the container with a sterilizing / disinfecting solution, and heating and drying the flexible container after the cleaning. That is, in the present invention, pre-cleaning and finish cleaning are performed in a state where the entire container is largely unfolded and its inner wall surface is exposed to the outside. Therefore, the washing, sterilization / disinfection and drying of the container can be performed continuously and efficiently, and the result of the washing can be visually confirmed, so that the container can always be used as a clean container. Hygienic management is easier when transporting beverages such as milk and juice.

[0032] The invention according to claim 18 specifies the method of deploying the container. That is, the flexible container is in the peripheral portion of the non-opening / closing portion, and has a container hanging piece at at least two places on the periphery of the top surface, and a bottom part fixing piece at at least two places on the periphery of the bottom part. The flexible container is automatically opened and opened when the container hanging piece and the bottom surface fixing piece are pulled up so as to be pulled.

[0033] The invention according to claim 19 defines the method of cleaning between the pre-cleaning with the cleaning liquid and the finish cleaning with a sterilizing / disinfecting solution, and the pre-cleaning and the finish cleaning are performed by using at least a flexible container. Immerse in cleaning solution and disinfectant solution,

The sterilizing and disinfecting solution is an aqueous solution of sodium hypochlorite having a concentration of 300 ppm or less.

According to a twenty-third aspect of the present invention, provisional cleaning is performed before the cleaning method according to the sixth or seventeenth aspect is performed, as described above. That is, the preliminary cleaning is performed before the cleaning and after the discharge of the transport liquid, by adjusting the size of the flexible container after the discharge of the transport liquid to an inflated state, by injecting the cleaning liquid from the inlet / drain port, Through the degassing means of the liquid stirring port, the air in the container is discharged together with the increase in the injection amount of the cleaning liquid, and after the injection amount of the cleaning liquid reaches a predetermined filling amount, the cleaning liquid is transferred to the transport liquid. Discharging the liquid from the inlet / outlet together with the residual liquid to the outside.

According to a twenty-fourth aspect of the present invention, after the cleaning liquid is discharged by the temporary cleaning, the flexible container is further folded to guide the remaining liquid therein to the liquid discharge port,
The remaining liquid is discharged from the inlet / drain port. As described above, this temporary cleaning is to temporarily transfer the liquid to be transported from the flexible container to another container at the destination, and then to perform temporary cleaning on the spot. Will be loaded on a transport vehicle and return to the return route. At this time, if the flexible container is loaded on the vehicle with the spread, the other articles cannot be transported. Therefore, after the temporary cleaning is completed, the flexible container is naturally folded and stored in a portion that does not hinder the loading. However, in the present invention, the remaining liquid in the container is filled and drained in this folding. And most of the remaining liquid in the container is naturally discharged from the inlet / drain port at the stage of folding.

As shown in the figure, the front and rear support wall portions 44 installed on the loading platform 41 of the vehicle 40 are wound around the hooking portions 44e, and the hook-and-loop fastener engaging portions 10b 'are engaged with each other and fixed.

In the present invention, the container suspension piece 10
a and the bottom surface fixing piece 10b, the airtight waterproof slide fastener 20 is opened, and the flexible container body 10 is unfolded.
When the container 1 is subjected to cleaning, sterilization / disinfection, or drying processing, the container 1 is used to be suspended from a hook of a hoist 130 as shown in FIGS.

In the present invention, the mounting position of the airtight waterproof slide fastener 20 is particularly important. FIG. 4 shows the relationship between the mounting positions. According to the drawing, the airtight waterproof slide fastener 20 is placed at a height h from the bottom surface 12.
Is approximately 1/3 of the height H of the entire container, and the airtight waterproof slide fastener 20 is attached to the front surface portion 13a, the left side surface portion 13d, and the rear surface portion 13b of the peripheral surface portion 13 of the container body 10.
1, and the end of the airtight waterproof slide fastener 20 is separated from the front surface 13a and the rear surface 13b to the right side 1 as shown in FIG.
The upper and lower stoppers 20a and 20b of the airtight and waterproof slide fastener 20 extend from the front and rear ends of the right and left sides 13c to a position where the required length is inside.
c at the extending positions.

The upper stopper 20a and the lower stopper 20 are most susceptible to an impact load during liquid transport, and it is particularly preferable to avoid attaching them to the front surface 13a. In the embodiment shown in FIG. The reason why the stoppers 20a and 20b are provided on the front and rear end sides of the right side surface portion 13c of the container body 10, respectively, is that the portion where the load applied to the container body 10 during liquid transportation is the largest is the front and rear surface portions 13a and 13b of the container body 10.
In particular, when the stoppers 20a and 20b are arranged on the front portion 13a where a large impact load acts upon a sudden stop, the stopper 2
This is because 0a and 20b are easily damaged at an early stage.

Incidentally, according to an experiment, in the above-described flexible container 1 having the form shown in FIG.
290mm × width 2290mm × height 1140mm,
When 11 m ³ of liquid was sealed in the container 1 and the stress acting during transportation at the positions indicated by to in the figure was analyzed, the stress applied during braking was the position near the front surface 13 a of the container top surface 11. Is the largest, then the position of the front portion 13a 200 mm below the container top surface 11, and the portion with the lowest stress is the position of the front portion 13 a 200 to 300 mm above the container bottom 12. In particular, the stress at the position of the front part 13a of 200 to 300 mm above the container bottom part 12 is extremely small with respect to other parts, and is approximately one third of the position of the container top part 11 near the front part 13a.

According to the results of this analysis, the mounting position of the airtight waterproof slide fastener 20 with respect to the flexible container 1 is set closer to the lower side than the upper side, so that abrupt braking due to sudden braking during liquid transport or the like. It can be seen that the change in stress is small and the lateral pulling force acting in the transverse direction of the airtight waterproof slide fastener 20 can be reduced. The mounting position of the airtight waterproof slide fastener 20 is determined by the number of times the container 1 is used, the number of braking operations during the liquid transport (the number of times of normal braking and rapid braking), the service life of the container 1, and the service life of the airtight waterproof slide fastener. However, it cannot be uniformly defined, but in FIG. 4, at least the mounting height h from the bottom surface 12 of the container body 10 is 1/1 / the total height H.
It is preferable to mount at a height position of 2 or less.

FIGS. 5 and 6 show the structure of the airtight waterproof slide fastener 20 and the manner in which the slide fastener 20 is attached. As can be understood from these drawings, the airtight waterproof slide fastener 20 has a substantially lateral Ω-shaped one side edge of a waterproof tape 21 in which a waterproof layer such as a polyurethane resin having elasticity is coated on a fiber base cloth. And a pair of fastener stringers 23, 23 with the engaging teeth 22 attached to the bent portions 21c, disengage the opposed engaging teeth 22 and oppose the upper and lower vertical parts 21c ',
21c "and a slider 24 for bringing them apart from each other. Examples of the material of the waterproof layer include various synthetic rubbers and polyvinyl chloride resins in addition to the polyurethane resin.

The bent portion 21c having a substantially lateral Ω shape constitutes a service tooth holding portion. The service tooth holding portion 22 holds the service tooth 22 on the service tooth holding portion so that the engaging head 22a protrudes. ,
The bent portion 21c is formed into a C-shaped work tooth clamper 2 from the outside.
5 to hold the engagement teeth 22 in place. The upper and lower ends of the bent portion 21c extend substantially vertically in a planar shape, and when the engagement teeth 22 are engaged, the corresponding portions of the other party are in close contact with each other to form an airtight waterproof structure. .

The airtight and waterproof slide fastener 2
0 is opened and closed by a sliding operation of the slider 24. At this time, the outside of the bent portion 21c to which the engagement tooth 22 is fixed is connected to the guide path 24 of the slider 24 as shown in FIG.
Guided by a. The guide path 24a of the slider 24 has a guide groove 24b on its ceiling surface and a slit on its bottom as shown in the figure to guide the upper and lower vertical portions 21c 'and 21c "of the bent portion 21c. 24c are respectively formed.

The airtight and waterproof slide fastener 20 is preferably attached to the container body 10 by high frequency welding or ultrasonic welding, not by sewing, in order to secure airtight and waterproofness. In the case of (1), the higher the affinity is, the higher the welding strength is. Therefore, it is preferable to use the same type of thermoplastic resin. In the present embodiment, a polyurethane resin is used as the coating material of the waterproof tape 21 and the container main body is used. Polyurethane resin is used as a resin material for covering the fiber reinforcing layer that constitutes 10. Of course, in the present invention, the coating material of the waterproof tape 21 and the coating material of the fiber reinforcing layer are not limited to the polyurethane resin, and other thermoplastic synthetic resin materials described above can also be used.

The hooks of the container hanging piece 10a and the bottom fixing piece 10b are provided at positions where they can be hooked as close as possible to each other. Therefore, when the container hanging piece 10a and the bottom fixing piece 10b are hooked on the hanging metal fitting 124, the flexible container 1 is developed in an inverted V-shape with the non-opening / closing portion 13e as a base point, and the inside of the container is exposed to the outside. I do.

When the container is unfolded in an inverted V-shape, the container suspension piece 10a and the bottom surface fixing piece 10b are pulled by a wire or the like in a direction away from each other as shown in FIG. Wash. At this time, the cleaning is performed in a state where the injection nozzle 129 is at least 1 m away from the surface of the flexible container 1 in the same manner as the cleaning by the facility 100 of the first embodiment. Next, as shown by a solid line in FIG. 14, the hoist 130 is driven to move the flexible container 1 directly above the cleaning tank 127.

FIG. 14 shows a cleaning procedure performed by the second cleaning equipment 120. As described above, the cleaning tank 127 is used.

After being immersed in an aqueous solution containing sodium hypochlorite for about 10 minutes to perform sterilization and disinfection, the container 1 is pulled out of the aqueous solution to complete the finish washing. Although illustration is omitted, in the present embodiment, after finishing cleaning is completed, the hoist 130 is driven to immerse the cleaned flexible container 1 in hot water in a hot water tank (not shown) to perform all cleaning steps. Is to be completed.

As described above, not only can the container 1 be washed, sterilized, and disinfected at a stretch in the opened state, but also in the first cleaning equipment, the same applies to the above-mentioned hoisting apparatus when shifting to the next drying step. By moving the container 130, the container 1 can be easily moved.
Since the liquid is exhausted in 0, the drying efficiency is also improved.

In such cleaning and sterilizing / disinfecting processes, the cleaning liquid and the sterilizing / disinfecting solution are sprayed without spray nozzles 131 and 13 as shown in FIG.
According to 2, it is also possible to sequentially inject into the developing inside of the container body 10 for processing. In the cleaning method shown in FIG. 15, the exclusive injection nozzles 131 and 132 for the cleaning liquid and the sterilizing / disinfecting liquid are used.

[0086] The equipment and method for main cleaning of the flexible container 1 for transporting liquid according to the present invention have been described above. The liquid transported by this type of flexible container 1 is a fresh beverage. Often it is. Therefore, if you return to the destination while replacing the liquid in the container with another container at the destination, the residual liquid in the container or the residue adhering to the inner wall of the container when returning to the source may generate bacteria or mold. It often rots. Therefore, according to the present invention, the empty flexible container 1 is temporarily cleaned immediately after the liquid in the container is replaced with another container at the destination depending on the type of the liquid to be transported.

FIG. 17 to FIG. 19 show that the preliminary cleaning can be performed on a transport vehicle. In the first place, as described above, when filling the flexible container 1 with the liquid, the hand blower 45 for blowing air into the container 1 to inflate the container 1 and the above-described liquid discharge port are provided on the floor of the transport vehicle 40. 1
5 is provided with an opening / closing valve 47 used for connecting a hose, and a supporting wall portion 44 made of a steel material panel for restricting and supporting movement of the front and rear surface portions 13a and 13b of the container 1 after liquid filling. A wave-dissipating bar (not shown) for regulating the vertical movement of the top surface 11 of the flexible container 1 during liquid transport can be installed above the container 1. Therefore, in the present embodiment, the temporary cleaning is performed by using the above-described members mounted on the vehicle 40.

Now, in order to temporarily clean the flexible container 1 on the vehicle, first, the support wall portion 44 and the wave-dissipating bar are set at predetermined positions, and the bottom portion 12 is placed on the floor between these members. The flexible container 1 immediately after discharging the liquid is placed downward and placed in an expanded state (see FIG. 17). At this time, an opening / closing valve 47 is attached to the liquid supply / discharge port 15 of the container 1 and all other openings are closed. In the illustrated example, the floor surface of the vehicle 40 is used in a horizontal plane, but for example, as shown in FIG. 20, a wedge-shaped washing table 40 ′ is placed on the floor surface of the vehicle 40,
The flexible container 1 may be spread and placed on this in the same manner as in the first cleaning equipment to perform the temporary cleaning. The washing table 4
If 0 'has a structure that can be disassembled and assembled, it can be always provided in the vehicle.

Next, a hand blower 45 is attached to the opening / closing valve 47, the valve 47 is opened, and air is blown into the container 1 to adjust the container to an inflated state without wrinkles (FIG. 1).
8). Next, after closing the open / close valve 47, the hand blower 45 is detached from the valve 47, a drainage hose 48 is connected, the open / close valve 47 is opened, and hot water of about 60 ° C. is injected through the drainage port 15. (See FIG. 19).
At the time of this liquid injection, the airtight waterproof slide fastener 35 attached to the liquid stirring port 14 is opened as necessary,
The air in the container 1 is discharged according to an increase in the amount of the cleaning liquid injected. After the injection amount of the warm water reaches the predetermined filling amount, the warm water is discharged to the outside from the injection / discharge port 15 together with the remaining liquid of the transport liquid.

When it is confirmed that the hot water has been discharged, the flexible container 1 is folded. FIG. 21 shows an example of a procedure for folding the flexible container 1 on a vehicle. First, the flexible container 1 in a state where the cleaning liquid inside is discharged and spread as shown in FIG. 3A is divided into 1/3 of the left and right widths as shown by arrows in FIG. Is folded upward.
Next, the container 1 is folded back from the front end side toward the rear end side. At this time, the remaining liquid inside the container 1 flows out from the liquid inlet / outlet port 15 projecting from the rear end so as to be squeezed. The flexible container 1 thus folded
Is unloaded from the bed of the vehicle 40 and stored in a predetermined container storage unit (not shown). Note that the procedure for folding the flexible container 1 can also be applied to the procedure for folding the flexible container 1 at the time of storage in the storage shelf after the main washing.

As is clear from the above description, the flexible container 1 for transporting liquid according to the present invention has a non-opening / closing portion formed on a part of the peripheral surface and an airtight waterproof slide fastener on the peripheral surface. Since the top 20 and the bottom can be separated by attaching the slide fastener 20, the inside of the container can be exposed to the outside by opening the slide fastener 20 as needed. As a result, for example, when the cleaning of the flexible container 1 is completed, the state of the inside of the container can be visually confirmed, so that reliable cleaning can be performed.

Further, by attaching the airtight and waterproof slide fastener 20 as described above, the inside of the container 1 can be opened and the inside and outside can be washed simultaneously by opening the slide fastener 20 for washing, thereby enabling efficient washing. It becomes possible. Further, since the flexible container 1 has the container suspension pieces 10a and the bottom surface fixing pieces 10b attached to at least four corners, the container 1 can be simply fixed to the floor of the vehicle. Thus, they can be effectively used at the time of washing.

Further, in the cleaning method according to the present invention, the liquid agitating port 14 and the pouring / discharging port 15 formed in the flexible container 1, or the liquid is filled in the flexible container 1 for transportation. Therefore, various devices and members equipped in the transport vehicle are used not only for the stirring operation at the time of filling the transport liquid and the injection and discharge of the liquid, but also at the time of transport, as described above. The present invention effectively utilizes structures and devices for various types of cleaning, and is an extremely useful invention in the technical field.

It should be understood from the above description that the present invention is not limited to the above embodiment.
Various modifications are possible within the scope described in the claims.
