Description

  The present invention relates to a transporting container having an inner bag for storing a liquid or a viscous body, in particular, a discharge auxiliary tool used in a container for storing a viscous body having a high viscosity, and a discharge method using the same.

  Containers used for transporting industrial oils and fats such as grease, creamy products such as printing inks, adhesives, paints, body soaps, kneaded foods such as mayonnaise and various other highly viscous liquids, i.e. Conventionally, metal or plastic tanks have been used. However, such tanks are relatively expensive, and the transport and storage efficiency of empty tanks is inferior. The cleaning of the pipes was troublesome.

  In recent years, a bag made of a synthetic resin film or the like is used as an inner bag in combination with an outer container such as an outer frame made of a rigid material that can be folded or disassembled, and the inner bag is discarded after one use. A liquid container that simplifies the cleaning work has been proposed (for example, Patent Document 1).

  In this case, in transporting a liquid having a relatively low viscosity, filling and discharging can be easily performed using the fluidity of the liquid, but a liquid having a high viscosity, a kneaded material having almost no fluidity, etc. In the case of this slime body, it is difficult to fill and discharge only by the fluidity of the viscous body itself. For this reason, for example, it is filled from a discharge port at the bottom of the bag by being pumped and filled by a pump, or sucked and discharged by a pump.

  By the way, when the stored item such as the viscous body is discharged by the suction force of the pump, the stored item is sucked and discharged from the vicinity of the discharge port, so that the upper surface of the stored item starts from the central portion. In accordance with this, the top of the inner bag is drawn from the center, and a part of the inner bag is sucked into the discharge port, thereby closing the discharge port, and as a result stored There is a possibility that the discharge of objects may be hindered, and there is a risk that the stored items may remain without being discharged sufficiently at the peripheral portion in the inner bag. In particular, in the case where the stored item is a high-viscosity viscous material having almost no fluidity, the above-described problem is likely to occur.

  For this reason, a flange cylinder having a long hole through which a stored item is passed is provided on the cylindrical discharge body attached to the discharge port portion so as to protrude inwardly, so that the inner bag is connected to the discharge port portion. An inner bag for a container has been proposed in which it is prevented from being sucked into the container and completely closing the discharge port (Patent Document 2).

In addition, it is a synthetic resin film container that is used as an inner bag inside an outer container such as a drum tube, and when the contents are sucked and dispensed in a container that stores frozen liquid, etc., the blocking of the dispensing path is prevented. In order to efficiently suck and dispense the contents, it has been proposed to insert a flow path securing member made of a net-like tube or the like (Patent Document 3).
Japanese Patent No. 3769653 JP 2004-182275 A JP 2005-298038 A

  As in the case of Patent Document 2, simply preventing the inner bag from adhering to the discharge port part, the stored matter such as a viscous body is discharged from the vicinity of the discharge port part by suction by the pump. When the stored item is discharged to some extent and the inner bag is adsorbed so as to cover the entire discharge body, the discharge of the stored item is hindered. As a result, the stored item inside is completely discharged. There is a risk that it will remain. Further, as the stored items are discharged and reduced, even if the inner bag for the container is folded and overlapped on the bottom of the container, the stored items become more difficult to be discharged and the remaining undischarged residue. The amount increases.

  In addition, as in Patent Document 3, it is necessary to insert a flow path securing member inside a synthetic resin film container used as an inner bag because the manufacturing of the container (inner bag) is troublesome. When the flow path securing member is a rigid body, the container (inner bag) cannot be folded down in a low volume in handling until it is installed and set in the outer container, which makes it difficult to handle. In particular, in a container such as a high-viscosity viscous body, as an inner bag to be used for convenience such as a cleaning operation, it is configured by inserting the flow path securing member therein The flow path securing member is also discarded together with the inner bag, and cannot be used repeatedly, which is uneconomical.

  The present invention has been made in order to solve the above-described problems, and in a container having an inner bag for storing a liquid or a viscous body, when the stored item is sucked and discharged by a pump, the inner bag is provided. The discharge port can be prevented from being blocked up to the end, and can be discharged with almost no remaining contents, and can be used by being inserted into the inner bag as appropriate. The discharge assisting tool which can be easily separated and can be used repeatedly is provided, and further, a discharge method using the discharge assisting tool is provided.

  The present invention for solving the above-mentioned problems is a discharge auxiliary tool used in a container having an inner bag for storing a liquid or a viscous body, and is inserted into the inner bag through an opening or an inlet provided in the upper portion of the inner bag. It is possible to have a main part of a required length that can be inserted from the upper side of the stored item to the bottom of the inner bag or the vicinity thereof, and the main unit is formed by a net-like body having an opening through which the stored item can pass over the entire outer periphery. It has a cylindrical shape and is provided with a connecting cylindrical portion at one of the upper and lower ends of the main body, and is formed so that the stored items can be discharged in a state where a discharging pipe is connected directly or indirectly to the connecting cylindrical portion. It is characterized by becoming.

  The discharge auxiliary tool of the present invention is used when discharging a stored item such as a liquid or a viscous body in a container including the inner bag, and is a main component of the discharge auxiliary tool inserted and set in the inner bag. A discharge pipe is connected directly or indirectly to a connecting cylinder part at one end of the part, and is sucked and discharged by a pump. As a result, the inner bags can be brought into close contact with each other as the amount of the stored items decreases, and the discharge can be performed with almost no remaining until the end without fear of closing the discharge port.

  In particular, the main part of the discharge assisting tool has a cylindrical shape with a mesh body having openings in the entire outer periphery, and the suction force of the pump reaches the openings in the entire outer periphery through the inner holes of the main part. Even if the object is a viscous body, it can be efficiently discharged by being sucked over the entire outer periphery. Further, even if a part of the inner bag is in close contact with a part of the main part of the discharge assisting tool and closes some of the openings, the last part is sucked from the other opening part. Can be discharged. Further, the discharge assisting tool can prevent the inner bag from being folded on the bottom of the container.

  Further, the discharge assisting tool can be inserted into the inner bag and can be used by being inserted and set appropriately, and can be handled separately from the inner bag, so that it does not interfere with the folding until the inner bag is used, and after use. By removing the discharge assisting tool, only the inner bag can be discarded, and the discharge assisting tool can be used repeatedly.

  In the discharge assisting tool, in a container having an inner bag having a discharge port part to which a discharge pipe is connected at the bottom, the main part has a larger diameter than the discharge port part of the inner bag. And a connecting cylinder part that can be fitted into the discharge port part is provided at the lower end, and can be held in an upright state by fitting the connecting cylinder part into the discharge port part. It can be made.

  In this case, when discharging the sticky body or the like stored in the inner bag, the discharge assisting tool is inserted from the opening or inlet of the upper portion of the inner bag, and the connecting cylinder portion at the lower end portion is connected to the bottom portion of the inner bag. It is inserted into the discharge port and inserted and held in a standing state. In this use, the opening or inlet of the upper part of the inner bag is closed, and the upper part of the inner bag is engaged with and held by the upper end part of the discharge assisting tool or the opening part with the lid of the outer container. deep. Thereby, while restricting the inner bag from being folded on the bottom of the container, as described above, the stored item inside can be efficiently removed from the outlet port through the opening and the inner hole of the main part of the discharging auxiliary tool. Can be discharged.

  In the discharge assisting tool, it is preferable that an insertion guide for the discharge port portion is provided at the lower end of the connecting tube portion, which is tapered in a shape that does not hinder the flow of stored items. Thus, even if the discharge port at the bottom of the inner bag is not visible from above due to the stored items inside, the tip of the discharge port can be found by searching the position of the discharge port with the insertion guide. As long as it is inserted into the connector, the connecting tube portion can be inserted into the discharge port portion as if it is dropped, and it is easy to insert and set from above the stored items during discharge. In addition, as described above, it is possible to efficiently discharge the stored items in the interior with almost no remaining.

  In the discharge assisting tool, a connecting cylinder portion for connecting a suction discharge tube to the upper end of the main body portion may be provided. In this case, in a container that sucks and discharges the stored items from the inlet at the top of the inner bag by a pump, for example, a container having an inner bag that does not have a discharge port at the bottom, The auxiliary tool can be inserted and set in the inner bag, and the discharge tube can be connected to the connecting tube portion protruding from the inlet. In this use as well, the suction force by the pump can be applied to the entire area of the main body as described above, and the internal storage can be efficiently discharged without remaining almost to the end.

  In the discharge assisting tool according to the present invention, the main body is formed by arranging a plurality of rod-shaped wires at a required interval in the circumferential direction on the outer peripheral portion of an annular disk arranged at intervals in the longitudinal direction. It is possible to form an elongated hole defined by an annular disk and the rod-shaped wire material in the entire outer periphery. As a result, the rigidity as a discharge assisting tool is high and easy to handle, and when the connecting cylinder part is inserted into the discharge port part and standing, the standing state can be satisfactorily maintained, and cleaning after use is also possible. Easy to do.

  The main body may be formed in a cylindrical shape by a perforated plate having a large number of apertures or a mesh-like body having a shape-retaining property.

  Further, the present invention provides a discharge container connected to the discharge port part in a container including an inner bag having a discharge port part at the bottom and containing a liquid or a viscous body and an outer container covering the outside of the inner bag. As a discharging method when discharging the stored liquid or viscous body with the suction force of the pump through the pipe, the discharging auxiliary tool provided with a connecting cylinder part at the lower end of the main part is used, and the discharging is performed. The auxiliary tool is inserted into the inner bag from the opening or injection port at the upper part of the inner bag, and the connecting cylinder part is held in the standing state by being fitted into the discharge port part of the inner bag bottom part, With the opening or inlet of the upper part of the inner bag closed, the upper part of the inner bag is engaged with the upper end part of the discharge assisting tool or the opening part with the lid of the outer container so as not to fall downward. It is characterized by holding and discharging. Thus, as described above, while restricting the inner bag from being folded on the bottom of the outer container, the stored item inside can be discharged through the opening and the inner hole in the entire main portion of the discharge assisting tool. It can be discharged efficiently from the section.

  As described above, according to the discharge assisting tool of the present invention, in a container having an inner bag for storing a liquid or a viscous body, it is used when discharging stored matter such as a viscous body, and is inserted into the inner bag. The discharge tube is connected to the connecting cylinder portion at the upper and lower ends of the main portion of the discharge assisting tool set, and the suction or suction port is sucked by the pump while the opening or the injection port is closed. By discharging, the inner bags can be brought into close contact with each other as the amount of stored items decreases, and the discharge can be efficiently performed without remaining almost to the end without clogging the discharge port, so that substantially complete discharge is possible.

  Moreover, since the discharge assisting tool can be handled separately from the inner bag, it does not interfere with the folding up to the use of the inner bag, and the discharge assisting tool can be easily separated from the inner bag after use. Even when the bag is disposed of, it can be repeatedly used semipermanently by washing the discharge assisting tool, and it is not necessary to prepare each container, which is very economical.

  Next, the best mode for carrying out the present invention will be described based on an embodiment shown in the drawings.

It is a schematic sectional drawing shown. FIG. 5 is a cross-sectional view of a state in which the discharge assisting tool of the present invention is set in a state in which the liquid or viscous body to be stored is stored in the inner bag of the container, FIG. 6 is a partially cutaway perspective view of the upper side of the same, FIG. 7 is an enlarged cross-sectional view of the same discharge port portion, FIG. 8 is an enlarged cross-sectional view of the same injection port portion, and FIGS. 9A, 9B, 9C, and 9D illustrate the inner bag. FIG.

  In the figure, symbol A indicates a discharge assisting tool according to the present invention, and B indicates an example of a container for liquid or mucilage that uses the discharge assisting tool A. For example, as shown in FIG. 5, the container B has a discharge port 22 at the bottom 21, an inner bag 20 that stores liquid or viscous material, and an outer shape that is a rectangular parallelepiped shape, and supports the inner bag 20 from the outside. And an outer container 30.

  In the case of the figure, the outer container 30 has a bottom frame portion 32 mounted on a pallet portion 31, and a funnel-shaped bottom portion continuously inclined from the side plate in the bottom frame portion 32 toward the center portion. 33, and an opening 34 for setting a discharge port 22 of the inner bag 20 and a discharge pipe 25 with an open / close valve connected to the discharge port 22 at the center of the bottom 33. Is provided. On the bottom frame portion 32, four corners of the column 35 and four side wall plates 36 supported by the column 35 are provided, and an upper frame 37 is mounted thereon. A box body 38 is assembled and configured, and the box body 38 is configured as an outer container 30 that holds the inner bag 20 from the outside. The box body 38 is provided so that it can be assembled and disassembled, and the column 35 and the side wall plate 36 may be configured to be foldable.

  The inner bag 20 is made of a bag made of a single layer or multiple layers of a synthetic resin film such as a polyethylene film, a bag made of a combination of these and a tarpaulin sheet, or a rubber bag. A synthetic resin mouth member 22a composed of a cylindrical portion 22a1 and a flange portion 22a2 is joined to the central portion of the bottom portion 21 of the inner bag 20 by heat fusion means at the flange portion 22a2, thereby discharging the discharge. A mouth portion 22 is formed. In use, the cylindrical portion 22a1 of the mouth member 22a is inserted into the opening 34 provided in the bottom 33 of the outer container 30, and the flange portion 22a2 is supported by the receiving member 22b. The discharge pipe 25 is fastened to the downwardly facing cylindrical portion 22a1 of the mouth member 22a by clamping means or other fastening means. At the upper part of the inner bag 20 is provided an injection port 23 in which a synthetic resin port member 23a is joined by heat fusion means or the like, and can be opened and closed by a cap 24 screwed to the port member 23a. ing.

  The inner bag 20 is not limited to the case in which the discharge port 22 by the mouth member 22a is provided in the bottom portion 21 and the inlet 23 by the mouth member 23a is provided in the upper portion as in the above example. Can be implemented. For example, as shown in FIG. 10 (a), the opening 20a is continuously opened to the upper end with the same diameter as the trunk formed by folding into a gusset shape, and the opening 20a is placed in a band or a state in which liquid or viscous material is stored. A string opening (not shown) that is tightened to close or a cylindrical opening 20b having a diameter smaller than that of the trunk is continuously formed as shown in FIG. The cylindrical opening 20b is tightly closed with a band or string (not shown) in a state where the container is stored, or the same cylindrical opening 20b as shown in FIG. The shoulder 20c that is continuous from the body to the body is formed obliquely, or the front and back bodies 20-1 and 20-2 are vertically stacked and joined together at the periphery by means of fusion, as shown in FIG. And the same inlet in the center of the upper and lower front and back bodies 20-1 and 20-2. 3 and can be made in which a discharge mouth 22.

  And the discharge auxiliary tool A which concerns on this invention used for the said container B is generally provided with the following structures.

  As shown in FIGS. 1 to 4, the discharge auxiliary tool A of the present invention has an opening 20 a at the upper portion of the inner bag 20 while having an outer diameter larger than the discharge port 22 of the inner bag 20. 20b or the injection port 23, and a required length that can be inserted from the position above the stored item a to the bottom 22 or the vicinity thereof in the storage state of liquid or viscous body, particularly preferably before the start of discharge. The main body 10 has a length that reaches the bottom 22 from above the full storage item a, and the main body 10 has a cylindrical shape having an opening 11 through which the storage item a can pass over the entire outer periphery. I am doing.

  In the case of the figure, the main body 10 has a plurality of, for example, 10 as shown in the figure on the outer peripheral portion of the annular disc 12 made of a rigid material arranged at a predetermined interval in the longitudinal direction. An opening 11 having a long hole shape in the longitudinal direction defined by the annular disk 12 and the rod-like wire 13 is formed in the entire outer periphery, which is formed by a net-like body formed by arranging the rod-like wire 13 of the book, The stored item a is provided so as to pass through the opening 11. Reference numeral 14 denotes an inner hole that continues through the main body portion 10 in the longitudinal direction so that the stored item a can circulate in the longitudinal direction.

  The arrangement interval of the annular disks 12 and the arrangement interval of the rod-shaped wires 13 can be arbitrarily set in consideration of the shape retention strength and the discharge performance of the stored items a. For example, as shown in the figure, the arrangement interval of the annular disks 12 can be made smaller than the central portion at both ends in the longitudinal direction, or can be arranged at the same interval over the entire length.

  The main body 10 is formed in a net shape by the circular disk 12 and the rod-shaped wire 13 and, for example, a shape retaining property such as a perforated plate having a large number of openings such as punching metal or a wire net having a relatively coarse mesh. It is also possible to use what is formed into a cylindrical shape by a net-like body having a certain shape. From the viewpoint of shape retention strength in use or ease of cleaning after use, it is preferable to use the annular disk 12 and the rod-shaped wire 13.

  In any case, when used in the container B having the inner bag 20 having the discharge port 22 at the bottom 21, for example, at the upper and lower ends of the main body 10, the discharge port 22 is connected to the lower end. A connecting cylinder portion 15 connected to the discharge pipe 25 with the opening / closing valve is provided. Specifically, the main body portion 10 has an outer diameter larger than the discharge port portion 22 of the inner bag 20, and the connecting cylinder portion 15 formed at the lower end is smaller in diameter than the main body portion 10. It is formed so as to be able to fit into the discharge port 22, and is provided so that it can be held upright by the fitting of the connecting tube portion 15 into the discharge port 22.

  The connecting tube portion 15 has an outer diameter slightly smaller than the inner diameter of the discharge port portion 22 by the port member 22a, and can be fitted into the discharge port portion 22 with almost no gap. It is formed. That is, if a large gap is generated between the connecting cylinder portion 15 and the discharge port portion 22, the stored material enters the gap during suction and discharge by the pump. Therefore, the gap is preferably as small as possible. . On the other hand, the smaller the gap is, the more difficult it is to insert the connecting tube portion 15 into the discharge port portion 22, and it becomes difficult to perform the insertion operation when it is dropped from above the stored item a and inserted. Preferably has a gap due to a diameter difference of about 1 mm in diameter.

  In particular, an insertion guide 17 having a tapered shape is provided at the lower end of the connecting cylinder portion 15 so as not to obstruct the flow of the stored item a, and the distal end 17a of the insertion guide 17 is connected to the discharge port portion 22. It is more preferable in terms of the insertion operation that the connecting cylinder part 15 is provided so as to be fitted into the discharge port part 22 as long as it enters.

  The shape of the insertion guide 17 is a cross-shaped or Y-shaped guide member 18 bent as shown in the figure so that the crossing portion is at the lower end, and the tip 17a is rounded and formed in an inverted triangular shape. In addition, it is possible to implement various shapes that can exhibit the guide effect when fitted into the discharge port 22 without obstructing the flow of the stored item a. For example, the guide member 18 may be implemented by bending the lower end of the guide member 18 into a parabolic shape or semi-oval shape with a smaller diameter. In any case, it is preferable that the front end (lower end) is rounded as shown in the figure so that the inner bag 20 is not damaged during the insertion operation by dropping from above.

  Note that the end of the discharge assisting tool A opposite to the connecting cylinder 15, that is, the upper end, is provided with a cylinder 19 having the same diameter as the connecting cylinder 15 as shown in the figure. In addition, it is possible to close the end portion of the cylindrical portion 19, to be able to close the cylindrical portion 19 so that a cap (not shown) can be screwed to the cylindrical portion 19, The cylindrical portion 19 may be omitted, and the end portion may be formed by the annular disk 12.

  The usage state of the discharge assisting tool A of the present invention configured as described above will be described. When the inner bag 20 is assembled and set in the outer container 30 in the container B, the discharge assisting tool A is inserted into the inner bag 20 and the connecting cylinder 15 is inserted into the discharge port 22 at the same time. Although it can be set, there is a problem that a means for regulating swinging during transportation is necessary, so normally, when transporting by container B, etc., it is separated without being incorporated in container B. It is inserted and used when discharging the stored item a at the transportation destination.

  In this use, for example, when used in a container B provided with an inner bag 20 having a discharge port 22 at the bottom 21, the upper portion of the inner bag 20 or the inlet 23 is passed through the upper part with respect to the stored item a. The discharge assisting tool A is inserted so as to drop, and the connecting cylinder portion 15 provided at the lower end of the main body portion 10 is fitted into the discharge port portion 22 and held in the standing state. At this time, even if the stored item a is an opaque liquid or viscous body and the discharge port portion 22 is not visible from above, the discharge auxiliary tool A is moved up and down slightly, so that the connecting tube portion The insertion guide 17 connected to the lower end of 15 can be easily fitted so as to find the position of the discharge port 22. That is, if the distal end of the insertion guide 17 enters the discharge port portion 22, the connecting cylinder portion 15 can be fitted into the discharge port portion 22 as it is dropped.

  As described above, with the discharge assisting tool A inserted and standing, the upper opening of the inner bag 20 is tightly closed with a band or string body, or the inlet 23 is closed with a cap 24. The upper portion of the inner bag is held by the upper end portion of the discharge assisting tool A, the upper portion of the outer container 30, or a separately provided locking member so as not to fall.

  For example, as shown in FIGS. 6 and 8, the inner bag 20 is placed on two support frames 27 and 27 detachably mounted on frame portions 37 a and 37 a on opposite sides of the upper frame 37. Two split-type locking members 28a and 28b are provided to be held between both sides of the mouth member 23a forming the inlet 23, and the mouth member 23a is locked by the locking members 28a and 28b. And keep it from falling down. In the case of the figure, the one locking member 28a is provided on the support frames 27 and 27 so as to be slidable toward and away from the other locking member 28b, and fixed at an arbitrary position by a screw member 29. It is configured to be able to.

  Further, the upper end portion of the discharge assisting tool A is positioned so as not to swing so as to be positioned inside the injection port 23. Therefore, the discharge assisting tool A has a container size or the like such that the upper end portion is located inside the injection port 23 in a state where the connection cylinder portion 15 is fitted into the discharge port portion 22 and is erected. Accordingly, the length of the main body 10 is set. When the upper end portion has the cylindrical portion 19, the length is set so that the cylindrical portion 19 is positioned inside the injection port 23 and the end surface is in contact with or close to the inner surface of the cap 24.

  Thus, the stored item a is sucked and discharged by the suction force of the pump connected to the discharge pipe 25 connected to the discharge port 22 of the inner bag 20. Even if the inner bag 20 is slackened due to the decrease due to the discharge of the stored item a, there is no possibility that the inner bags 20 may be in close contact with each other or may block the discharge port portion 22 and hinder the discharge. It can be discharged smoothly with almost no residue until the end.

  In particular, the main body 10 of the discharge assisting tool A has a cylindrical shape with a mesh body having openings 11 in the entire outer periphery, and the suction force of the pump is opened in the entire outer periphery through the inner holes 14 of the main body 10. Therefore, even if the stored item a is a viscous body, it can be efficiently discharged by being sucked over the entire outer periphery. Even if a part of the inner bag 20 is in close contact with a part of the main body 10 of the discharge assisting tool A and closes some of the openings 11, It can be sucked out and discharged. Furthermore, the discharge assisting tool A can prevent the inner bag 20 from being folded on the bottom 33 of the outer container 30. For this reason, it is possible to efficiently discharge the stored item a to the end without almost remaining, and substantially complete discharge is possible.

  The discharge assisting tool A can be inserted into the inner bag 20 and inserted and set as necessary. Since the discharge auxiliary tool A can be handled separately from the inner bag 20, it is folded until the inner bag 20 is used. In addition, by removing the discharge assisting tool A after use, only the inner bag 20 can be discarded, and the discharge assisting tool A can be used repeatedly.

  The discharge auxiliary tool A according to the present invention is used by being inserted and set in the inner bag 20 as described above before the start of suction and discharge of the stored item a, and depending on the form of the container B, In a state where the suction and discharge of the stored item a from the mouth portion 22 has progressed to some extent, it can be inserted into the inner bag 20 and used.

  That is, with the suction and discharge of the internal storage item a by the pump, the atmospheric pressure acts on the outer surface of the inner bag 20, and the storage item a in the inner bag decreases so that the upper surface is lowered. Therefore, the discharge is hardly hindered until a certain amount of discharge has progressed. For example, when the discharge of about 1/3 to 2/3 has progressed, the upper opening of the inner bag 20 or the inlet 23 is opened. The discharge assisting tool A is inserted into the inner bag 20 in the same manner as described above, and the connecting cylinder 15 at the lower end is fitted into the discharge port 22 and held in the standing state in the same manner as in the above-described embodiment. The upper opening of the inner bag 20 or the inlet 23 is closed, and if necessary, the upper portion of the inner bag 20 is locked to the upper portion of the outer container 30 and the like so as not to fall, and suction and discharge are performed. In particular, if the outer container 30 of the container B is formed of a box body 38 in which the side wall plates 36 on the four side surfaces can be folded, the above-described insertion setting operation can be easily performed by opening the side wall plate 36 on one side surface. be able to. Also in this case, the stored item a can be discharged to the end efficiently with little remaining. Further, when the discharge assisting tool A is used as described above, the discharge assisting tool A may be shorter than the above-described embodiment.

  In the above-described embodiment, the case of using the container A including the bag body 20 having the discharge port portion 22 in the bottom portion 21 has been described. However, the discharge auxiliary tool A of the present invention is provided on the upper portion of the inner bag 20. It can also be used when the stored matter a such as a liquid or a viscous body is sucked and discharged from the inlet 23 by a pump, that is, when an inner bag having no discharge port is used. For example, depending on the type of liquid or viscous material to be stored, a structure that discharges from a discharge tube with a valve at the bottom of the container cannot be adopted due to the risk of leakage and the problem of cleaning work after discharge. It is necessary to suck and discharge the stored items from the upper part of the container without using a part. At this time, the discharge auxiliary tool A of the present invention can be used.

  In this case, as shown in FIG. 10, the discharge assisting tool A having the connecting cylinder portion 16 provided at the upper end of the main body 10 is used, and the discharge assisting tool A is located above the stored item a in the inner bag 20. The pumping tube 26 for suction by a pump is connected to the connecting cylinder portion 16 with the lower end positioned so as to be in contact with or close to the bottom portion 21 and used. Therefore, the connection pipe 16 is provided so that the end of the discharge pipe 26 can be connected.
