Field of the Invention The present invention relates to an inner bag composite container in which a resin-made inner side container is provided in a steel outer side container. L. «θ' - ϋ. ] 3 BACKGROUND OF THE INVENTION For example, in a steel container for accommodating a food or a liquid medicine, in order to prevent corrosion of the food or chemical solution directly contacting the inner surface of the steel container, the food is stored. The inner container made of a resin liquid is stored in the inner bag composite container 10 as shown in Fig. 5 in a steel outer container. In the inner bag composite container 10, the inner container 1 is formed of a polyethylene bag and formed in a bag shape, and an inlet and outlet lb for inserting and discharging the filler into the upper portion of the container is integrally formed with the container body portion. Further, the outer peripheral surface of the inlet and outlet lb is formed into a male thread shape. On the other hand, in the outer container 2 of the inner bag composite container 10, the body 2a made of a cylindrical steel plate and the bottom plate 2b made of a steel plate are wound around the storage portion. Then, after the inner container 1 is placed in the accommodating portion, the rim 2b and the top plate 2c are wound and sealed in a state in which the opening lb is formed by the opening of the top plate 2c made of a steel plate. The outer container 2 receives the inner bag composite container 10 of the inner container 1 made of resin. After the filler is filled into the container 10, the Q lb screw body 3 protrudes from the top plate 2c, and the filling of the filler is sealed. 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 2011 2011 2011 2011 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物 废弃物In addition, there is a strong call for classification and disposal according to materials. Even in the case of the above-described inner bag composite container 10, the sense of classifying the inner container 1 made of resin and the outer container 2 made of steel has been highly increased. Further, in the inner bag composite container 10, the filling material is mostly the above-mentioned food or medicine, and after the filling of the filling material by the inner container 1 due to hygienic or characteristic problems, the same filling material cannot be reinjected toward the inner container 1. There are many situations. Therefore, the inner bag composite container 10 is often used only once, and most of the inner bag composite container 10 is waste immediately after being discharged, and the amount of waste is large. Therefore, the amount of classified work is inevitably increased. On the other hand, in the inner bag composite container 10, as described above, not only the bottom plate 2b but also the top plate 2c is wound and fixed to the body 2a, and the bottom plate 2b and the top plate 2c cannot be easily removed by the body 2a. Therefore, in order to classify the inner container 1 and the outer container 2, that is, when the inner container 1 is taken out from the outer container 2, for example, by the same method as when the can is opened, for example, a method of cutting the top plate 2c around the periphery thereof is employed. This operation is very cumbersome, time consuming and labor intensive, and the work efficiency is extremely poor. Therefore, it is a major cause of hindering the increase in the classification waste rate of the inner bag composite container. 201144180 The present invention has been made to solve the above problems, and an object thereof is to provide an inner bag composite container which can be classified and discarded more easily than before. Means for Solving the Problems In order to achieve the above object, the present invention has the following constitution. That is, the inner bag composite container according to the first aspect of the present invention includes: an inner container made of resin, a bag shape that accommodates the filling material, and an inlet and outlet of the filling; and a steel can The utility model comprises a top body which is wound with a bottom plate for accommodating the inner container and which is detachable with respect to an open end of the body, and has a top opening which can protrude from the inlet and the outlet; and corresponds to an outer container. Further, the top plate may have a multi-ear type in which the claw of the top plate is locked to the top body. Further, the top plate may further include a fixing belt that is locked to the body. According to the inner bag composite container of the first aspect of the present invention, the top plate of the steel can of the inner container made of resin can be attached to and detached from the body. Therefore, when the inner bag composite container is discarded, the top plate facing body can be easily removed earlier, and the inner container can be easily taken out from the outer container. Therefore, the sorting of the inner bag composite container can be carried out very easily. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing an example of a configuration of an inner bag composite container in an embodiment of the present invention. 201144180 Fig. 2 is a view showing another example of the configuration of the inner bag composite container in the embodiment of the present invention. Fig. 3 is a view showing a modification of one of the inner bag composite containers shown in Fig. 2. Fig. 4 is a view showing another modification of the inner bag composite container shown in Fig. 2. Fig. 5 is a view showing the constitution of the prior inner bag composite container. I. Embodiment 3 Mode for Carrying Out the Invention An inner bag composite container according to an embodiment of the present invention will be described below with reference to the drawings. In the drawings, the same or similar components are denoted by the same reference numerals. The inner bag composite container 101 of this embodiment is shown in Fig. 1. The inner bag composite container 101 roughly divides the inner container 111 made of resin and the steel can 121 corresponding to the outer container in which the inner container 111 is housed. The inner container 111 has a bag-shaped inner end portion 111a for accommodating the filling material, and an inlet/outlet 111b for inserting and receiving the above-mentioned filling material by integrally attaching the main body portion 11la to the upper surface of the main body portion 11la. The resin material forming the end portion 111a and the inlet and outlet 111b is, for example, polyethylene, and the body portion 111a can be produced, for example, by blow molding. The canister 121 is equivalent to the cans specified in JIS Z1620 (1995) "Steel Barrels", and is also a "top-plate type" multi-ear type and belt type can. Further, Fig. 1 is a view showing the above-described multi-ear type. Such a canister 121 is roughly distinguished from a carcass 122, a bottom plate 123, and a top plate 6 201144180 124. The carcass 122 is formed by forming a steel sheet into a cylindrical shape and welding it by seams. Further, as shown in the figure, a handle (suspension) 128 is attached to the outer surface of the outer surface of the body 122. The bottom plate 123 is crimped and fixed to the body 122 to form a cup-shaped container portion. Further, a flange 122a is formed on the body 122 at the open end of the container portion. The top plate 124 is formed of a steel plate and has a structure in which the body 122 is detachable. That is, the top plate 124 of the inner bag composite container 101 is of the above-described multi-ear type, in which the top plate 124 is fixed to the body 122, and a plurality of claws 125 which are bendable are radially formed on the peripheral edge portion of the top plate 124. Further, in the top plate 124, an opening 124a through which the inlet and outlet 111b of the inner container 111 can protrude is formed. Further, in the above-mentioned JIS Z1620, the type of the can is further defined as a "T" shape called a cone barrel in which the body 122 is tapered, and a "S" which is called a straight barrel in the case where the body 122 is straight. shape. The bucket can 121 in the present embodiment may be any of a "T" shape and an "S" shape. In the can 121 having such a configuration, the inner container m is filled in the cup-shaped container portion formed by the body 122 and the bottom plate 123 in a state where the opening end side of the body 122 is aligned with the inlet and outlet 11 lb of the inner container 111. Then, the top plate 124 is placed on the bead 122a of the body 122, and the claws 125 of the top plate 124 are bent along the bead 122a in a state where the port 111b is protruded from the opening 124a of the top plate 124. The top plate 124 is fixed to the body 122 by this bending operation. Further, the lid body 3 shown in Fig. 5 is screwed to the inlet and outlet 111b which protrudes from the top plate 124. As described above, the inner bag composite container 101 of the present embodiment is completed. On the other hand, when the inner bag composite container 101 is classified and discarded, the claws 125 of the top plate 124 that are locked toward the bead 122a are pulled up, and the connection between the top plate 124 and the 胴201144180 body 122 is released. Thereby, the top plate 124 can be removed by the body 122. Further, the cover body 3 is removed, and the inner container in and the can 1212 can be separated. As described above, according to the inner bag composite container 1〇1 of the present embodiment, the inner bag composite container can be classified and discarded more easily than before. As described above, the inner bag composite container is often used only once, and the amount of waste is large. Therefore, the inner bag composite barrage 1 〇 1 ' of the present embodiment can perform the sorting operation very simply, thereby reducing the number of pieces that have not been previously classified, and can contribute greatly to the effective utilization of resources, and can also Greatly contribute to the consideration of the environment. In Fig. 2, an inner bag composite container 102 having the above-described belt type can 126 is illustrated. The inner bag composite container ιοί in Fig. 1 differs from the inner bag composite container 102 in Fig. 2 in the barrel 121 and the can 126, and the inner container ill has no changed portion. The difference between the barrel 126 and the above-described barrel 121 is that the shape of the top plate is different from that of the top plate, and the other points are the same. Therefore, only the top plate 127 of the can 126 in the inner bag composite container 102 and the configuration of the fixing band 131 will be described. The top plate 127 has a shape in which the claws 125 are removed from the top plate 124, and has an opening i27a for projecting the entrance and exit 111b of the inner container 111. The fixing belt 131 has a C-shaped annular member 1313 and a rod portion 131b attached to the annular member 13la. The annular member i31a has a three-shaped cross section sandwiching the top plate 127 and the bead 122a placed on the bead 12a of the body 122, and the inner bag composite container 1〇2 can be attached and detached by the operation of the rod portion 131b. In the can 126 having such a configuration, the inner container ill is filled in the cup-shaped container portion formed by the body 122 and the bottom plate 123 in a state where the opening end side of the body 122 is aligned with the inlet and outlet 11 lb of the inner container 111. After the 201144180, the top plate 127 is placed on the above-mentioned bead 122a of the body 122, and the top plate 127 is sandwiched by the annular member 131a of the fixing tape i3 i in a state where the entrance and exit σ 111 b protrudes from the opening 127a of the top plate 127. The peripheral portion and the bead 12 are locked by the operation member portion 131b. With the locking operation, the top plate 127 is fixed to the body 122. Further, the above-mentioned cover 3 is slid at the entrance and exit 1Ub which protrudes from the top plate 127. As described above, the inner bag composite container 1 〇 2 of the present embodiment is filled. On the other hand, when the inner bag composite container 1 is classified and discarded, the rod portion 131 b of the solid H 31 is operated to unlock the ring member 131 a, and the fixing belt 31 is removed from the inner bag composite container 1 2 Take it down. Thereby, the connection of the top plate 127 and the body 122 is released. The top plate 127 can be removed from the body 122. Further, the lid body 3 is removed, and the inner container m and the tub 126 can be separated. As in the case of the inner bag composite container 101 shown in Fig. 1, the inner bag composite container 102 as shown in Fig. 2 can be easily discarded in the classification of the inner bag composite container as compared with the case of the inner bag composite container 101 shown in Fig. 1 . Moreover, by making the classification operation very simple, the number of pieces that have not been previously classified can be reduced, which can greatly contribute to the effective utilization of resources, and can greatly contribute to environmental considerations. Further, as a modification of the inner bag composite container 1A shown in Fig. 2, the inner bag composite container 102-2 shown in Fig. 3 and the inner bag composite container 102 shown in Fig. 4 may be used. Form of -3. With respect to the inner bag kneading container 102 shown in FIG. 2, in the can U6-2 of the inner bag composite container 1〇2_2 shown in FIG. 3, the handle 128 is removed from the body 122 of the can 126, and A handle 丨 28-2 is attached to the center of the top plate 127. Further, the carcass of the can 126-2 is labeled 201144180 "122-2", and the top plate is labeled "129". The top plate 129 is attached to the point where the handle 128 is attached and the point where the reinforcing embossing 129a is provided, unlike the top plate 127. Further, in the top plate 129, the formation of the embossing 129a may be omitted. Further, in the tank 126-3 of the inner bag composite container 102-3 shown in Fig. 4, the barrel 126-2 shown in Fig. 3 has a shape in which the convex portion 135 is further removed by the body 122-2. . In addition, the carcass of the bucket can be labeled "122-3". The other configuration of the inner bag composite container 102-2 shown in Fig. 3 and the inner bag composite container 102-3 shown in Fig. 4 is the same as that of the inner bag composite container 102 shown in Fig. 2. The inner bag composite container 102-2 shown in Fig. 3 and the inner bag composite container 102-3 shown in Fig. 4 are also fixed by the same as the inner bag composite container 102 shown in Fig. 2 The belt 131 is removed from the inner bag composite containers 102-2 and 102-3, and the inner bag composite container can be classified and discarded. At this time, in the inner bag composite container 102-2 shown in FIG. 3 and the inner bag composite container 102-3 shown in FIG. 4, since the handle 128-2 is provided on the top plate 129, it is as shown in FIG. The inner bag composite container 102 has an advantage that the top plate 129 can be attached and detached to the carcasses 122-2 and 122-3 more easily. Further, in the inner bag composite container 102-3 shown in Fig. 4, the manufacturing process without the convex portion 135 can be reduced, and the cost can be reduced. Further, an inner bag composite container having a configuration in which the respective inner bag composite containers 101, 102, 102-2, and 102-3 shown in Figs. 1 to 4 are appropriately combined can be produced. Industrial Applicability The present invention is applicable to an inner bag composite container in which a resin inner side 10 201144180 container is provided in a steel outer container.
