Definitions

  • This invention relates to a method of setting a bag, etc. in a liquid container used for transporting a liquid, such as various kinds of chemicals or liquid food, and to a liquid container.
  • Metal or plastic tanks have usually been employed as containers for holding and transporting liquids, such as various kinds of chemicals, liquid food or beverages, or liquid paints, but these kinds of tanks have been considerably expensive, have been inefficient in transportation and storage when they are returned from the destination after having been emptied, and have been very inconvenient in their cleansing for repeated use, especially the cleansing of their discharge tubes having valves.
  • the liquid container disclosed in the above literature has a bottom supporting body for supporting a container bag on a pallet body, the bottom supporting body has an opening in the center of its funnel-shaped bottom and its bottom has under the periphery of its opening an engaging portion into which a mounting flange formed at one end of a discharge tube having a valve is laterally engageable, so that the discharge tube having a valve may be detachably mounted by the engagement of the flange with the engaging portion.
  • the bag can be connected with the discharge tube if the tubular portion of a mouth member attached for a liquid outlet at its bottom is fitted into the end of the discharge tube.
  • This liquid container allows the discharge tube having a valve to be set in position relatively easily even by a job done under its bottom supporting body, but as the connection between the discharge tube and the mouth member at the bottom of the bag is merely by axial fitting, the sliding contact surfaces formed therebetween are not sealed satisfactorily despite any O-ring or other packing disposed therebetween, so that it is likely that a leak may be caused by a liquid pressure and make the user feel uneasy especially in the event that the container holds a dangerous substance, such as a chemical.
  • this invention is aimed at providing a method and a liquid container which facilitate the work of setting a container bag, a discharge tube having a valve, etc. in position and enables it to be done easily and safely by sealing a joint between a mouth member at the bottom of the bag and the discharge tube so tightly that there may not be any fear of liquid leakage, or of any remaining liquid dripping down when the bag is taken out, and a liquid container.
  • the discharge tube can be set in the frame by being passed through the opening in its bottom supporting portion with the discharge tube having a valve connected to the mouth member at the bottom of the container bag, the work of setting it in position can be performed easily and efficiently, while the joint between the mouth member and the discharge tube can be held in a tightly sealed state.
  • the disconnecting work of taking it out can be performed easily, since the discharge tube can be drawn up through the opening in the way opposite to what has been stated above.
  • the work of connecting the discharge tube to the mouth member and disconnecting it therefrom can be performed easily outside the frame.
  • the work outside the frame is easy to perform, since it is easy to ensure, when disconnecting it, that no remaining liquid drips down through the mouth member, even if any liquid may remain in the bag.
  • a supporting plate be provided removably on the bottom supporting portion along the periphery of its opening so as to be loosely or tightly fitted about the tubular portion of the mouth member to support its flange.
  • the supporting plate provides a rigid and reliable support for the mouth member on the bottom supporting portion along the periphery of its opening even if its opening may have a relatively large diameter to pass the discharge tube therethrough, and the supporting plate can be set in position easily when the discharge tube is set in position.
  • the supporting plate is preferably of the type split in two parts so as to be fitted about the tubular portion of the mouth member and set on the bottom supporting portion along the periphery of its opening when the discharge tube has been passed through its opening, whereby the work of setting it in position is further facilitated, as it is undoubtedly easy to have the supporting plate fitted about the tubular portion of the mouth member and set on the bottom supporting portion along the periphery of its opening when the discharge tube has been passed through its opening.
  • the liquid container preferably has a clamp type connecting structure by which the end of the tubular portion of the mouth member and the end of the discharge tube having a valve are connected to each other in a liquid-tight fashion.
  • the clamp type connecting structure is preferably of such construction that, while a protruding edge is formed about each of the ends of the tubular portion of the mouth member and of the discharge tube and has an inclined surface on its side opposite its side where those ends face each other, it includes a clamp member having along its inner periphery a tapered surface capable of being fitted about the protruding edges and tightening them into close contact with each other and a packing device disposed between the ends of the tubular portion and the discharge tube to connect them in a liquid-tight fashion upon tightening of the clamp member. It makes it possible to connect the ends of the mouth member and the discharge tube easily and reliably with a tight seal therebetween and provides a state of connection which is free from any fear of liquid leakage, etc.
  • the mouth member may be formed as a single body from a synthetic resin and its tubular portion may have a circumferential annular packing ridge formed on its end surface facing the discharge tube, while the end surface of the discharge tube facing it has a circumferential groove in which the ridge may be fitted at its top. This arrangement also makes it possible to connect the ends of the mouth member and the discharge tube easily and reliably and provides a state of connection which is free from any fear of liquid leakage, etc.
  • 1 is a container bag having a bottom to which a mouth member 2 for a liquid outlet is attached
  • 3 is a discharge tube having a valve and connected to the mouth member 2
  • 5 is a frame having a bottom supporting portion 50 for supporting the bottom of the container bag 1 .
  • a pallet 6 is situated under the bottom supporting portion 50 as an integral part thereof.
  • the container bag 1 is, for example, a bag made of a sheet formed from one or more synthetic resin films, such as polyethylene films, a bag made of a combination thereof with a tarpaulin sheet, or a rubber bag, and has a liquid inlet 11 made substantially in the center of its top and having a cap, and a liquid outlet formed in the center of its bottom and having the mouth member 2 attached thereto as stated above.
  • the bag 1 is made by, for example, welding two upper and lower synthetic resin films 1a and 1b to each other along their periphery 1c to form a flat and spread bag and forming the liquid inlet 11 and the liquid outlet for the mouth member 2 substantially in the centers of the upper and lower films 1a and 1b, respectively, as shown in FIGS. 2A and 2B , so that it may expand as shown by chain lines in FIG. 2A when air or its contents are introduced thereinto.
  • a bag formed in any other way will, of course, be useful, too.
  • the mouth member 2 for the liquid outlet is a molded product of a synthetic resin, such as a polyethylene resin and has a tubular portion 21 for connection with the discharge tube 3 having a valve and a flange 22 extending from one end of the tubular portion 21, as shown in an enlarged form in FIG. 3 , etc. , and the bag 1 has its bottom welded under heat or otherwise secured along its liquid outlet to the flange 22 in a sealed way.
  • the other end of the tubular portion 21 and one end of the discharge tube 3 having a valve are so formed as to be capable of being connected end to end liquid-tightly by, for example, a clamp type connecting structure as will be described later, with a packing device 4 held therebetween.
  • the flange 22 usually has, for example, a substantially square shape with all the corners rounded or a circular shape, though it may alternatively have an oval or pentagonal shape or a polygonal shape with more angles.
  • the discharge tube 3 having a valve is of a metal, mainly stainless steel, and comprises a substantially L-shaped elbow 31 connected with the tubular portion 21 and a mouthpiece member 32 having a valve 34 and connected to the elbow 31 by an adequate connecting device.
  • a protruding edge 23 or 33 is formed about each of the ends of the tubular portion 21 of the mouth member 2 and of the discharge tube 3 and has an inclined surface 23a or 33a on its side opposite its side where those ends face each other and the protruding edges 23 and 33 can be tightened into close contact with each other by a clamp member 7 fitting their outer periphery, as shown in FIGS. 3 to 5 .
  • the clamp member 7 comprises two semi-annular portions 72 linked together by a link portion 73 of the hinge construction and each having along its inner periphery a tapered surface 71 fitting the inclined surface 23a or 33a, while the opposite ends of the semi-annular portions 72 from the link portion 73 can be united together by a screw member 74, so that the clamp member 7 may be able to connect the ends of the tubular portion 21 and the discharge tube 3 together rigidly if the screw member 74 is tightened when the semi-annular portions 72 are fitted about the protruding edges 23 and 33, as shown in FIG. 5 .
  • the mutually facing surfaces of the ends of the tubular portion 21 and the discharge tube 3 have grooves 23b and 33b, respectively, in which a packing ring 4a like an O-ring as the packing device 4 can be fitted on its opposite sides so as to be held between the ends connected to each other and thereby form a liquid-tight joint which is free from any fear of liquid leakage, etc.
  • the packing device 4 the packing ring 4a formed from a rubber material, etc. separately from the mouth member 2 as stated, it is also possible to, for example, utilize the material of the mouth member 2 formed from a synthetic resin and form a circumferentially extending annular ridge 4b on the end surface of the tubular portion 21 as an integral part thereof so that the ridge 4b may be fitted in the groove 33b in the end surface of the discharge tube 3 to perform a packing function between the ends of the tubular portion 21 and the discharge tube 3 when they are tightened together into close contact by the clamp member 7 as described before, as shown in FIG. 7 .
  • This arrangement eliminates the necessity of using any separate packing ring, is economical owing to a corresponding reduction in the number of parts as required and also makes their connection easier.
  • the clamp type connecting structure as described before is, among others, preferable from the standpoints of easy connection, joint sealing, etc.
  • clamp type connecting structure as described before can be used for connecting the elbow 31 and the mouthpiece member 32 for the discharge tube 3.
  • the bottom supporting portion 50 of the frame 5 has a funnel-shaped bottom plate 51 having four sides inclined inwardly and downwardly.
  • the angle of inclination of the bottom plate 51 may be selected to suit the viscosity of the liquid to be transported, etc.
  • the bottom plate 51 has in its center an opening 52 through which the discharge tube 3 having a valve and connected to the tubular portion 21 of the mouth member 2 can be passed, and a supporting plate 55, for example, a supporting plate 55 split in two parts as shown in FIGS. 8 to 10 , can be mounted removably on a peripheral portion 53 around the opening 52 for supporting the flange 22 of the mouth member 2 when it is loosely or tightly fitted about the tubular portion 21 of the mouth member 2.
  • the bottom plate 51 has in its center a, for example, square area 51a formed slightly below its surroundings and defining a substantially horizontal surface, the opening 52 being formed in the center of the area 51a defining a horizontal surface, and the supporting plate 55 can be fitted and set in the area 51a.
  • the opening 52 may be possible to shift the opening 52, as well as the area 51a, forward or backward or to the right or left within the central area of the bottom portion, it is in practice preferable to situate them in their central position.
  • the supporting plate 55 is formed from a synthetic resin board, a particle board or a board of another rigid material, and is composed of two split halves 55a and 55b formed by splitting centrally in two parts a, for example, square board capable of being fitted in the area 51a, as shown in FIG. 8 .
  • Each of the split halves 55a and 55b has a recess 56a or 56b formed in the middle of its split edge and capable of being fitted about the tubular portion 21 of the mouth member 2.
  • the split halves 55a and 55b can be inserted under the flange 22 of the mouth member 2, joined together by having its tubular portion 21 fitted loosely or tightly in their recesses 56a and 56b and set on the peripheral portion 53 in the area 51a to thereby support the flange 22 of the mouth member 2 after the discharge tube 3 connected to the mouth member 2 has been passed through the opening 52 as stated before.
  • 54 is a heat-insulating, as well as protective, board attached to the inside of the bottom plate 51.
  • the supporting plate 55 for supporting the flange 22 of the mouth member 2 can alternatively be formed from a single board of the same material having an opening 56 with a diameter larger than the outside diameter of the tubular portion 21 of the mouth member 2 at its end, particularly the outside diameter of its protruding edge 23, so that it may be fitted loosely about the tubular portion 21 of the mouth member 2 and set on the peripheral portion of the opening 52, as shown in FIGS. 11 to 13 .
  • the supporting plate 55 according to this example may remain loosely fitted about the tubular portion 21 of the mouth member 2, as shown by chain lines in FIG. 11 , until the discharge tube 3 having a valve is connected to the end of the tubular portion 21 by the clamp type connecting structure as described before, and after the discharge tube 3 having a valve has been connected to the end of the tubular portion 21 by the clamp member 7 , the discharge tube 3 may be passed through the opening 52 as shown in FIG. 12 to have the supporting plate 55 set on the peripheral portion of the opening 52, while the discharge tube 3 can be set in position as described before.
  • the opening 52 in the area 51a does not necessarily have to be circular as shown, but may also be of any other shape, such as oval or polygonal, if it allows the discharge tube 3 having a valve to pass therethrough.
  • the peripheral portion of the opening has the supporting plate 55 support the flange 22 of the mouth member 2, as described before.
  • the supporting plate 55 does not have to be used if the flange 22 has a width or diameter which is larger than the diameter of the opening 52.
  • the use of the supporting plate 55 as described is, however, preferred to provide a stable support for the mouth member 2.
  • the bottom supporting portion 50 includes side frame members 57 situated along the four sides of the bottom plate 51 and supported by supporting posts 61 erected at the four corners of the pallet 6 and has under the bottom plate 51 a space in which the discharge tube 3 can be set, while the area 51a in the center of the bottom plate 51 has its surroundings supported by supporting posts 62 erected in the interior of the pallet 6.
  • the bottom supporting portion 50 and the pallet 6 are formed from a metal or other rigid material.
  • a fixing mechanism is provided above the pallet 6 for fixing and supporting the discharge tube 3 passed down through the opening 52 of the bottom supporting portion 50, as will now be described.
  • Tube supporting members 64 facing each other and having therebetween a spacing allowing the passage of the discharge tube 3 are connected to and supported by transversely spaced apart reinforcing members 63 extending from front to back and each formed from an angle, etc. above the pallet 6, and a pair of mounting devices 65 are installed on the tube supporting members 64, respectively, having therebetween a spacing making room for the elbow 31 of the discharge tube 3.
  • Each of the mounting devices 65 includes one of two substantially hook-shaped supporting members 66 protruding upwardly from the tube supporting member 64 and facing each other and one of two fixing bolts 67 supported by the supporting members 66 so as to be capable of being erected and protruding above the top plates of the supporting members 66 when erected, tightening screws 68 being threadedly engaged with the fixing bolts 67, respectively, as shown inm FIGS. 14 and 15 .
