[Embodiment of device]

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of a container according to an embodiment, FIG. 2 is a perspective view showing an outer appearance of the container, and FIG. 3 is an enlarged sectional view of a portion A shown in FIG.

In FIGS. 1, 2, and 3, the container is a container commonly referred to as an 18-liter can. The container comprises an inner container 1, an outer container 2 and a lid 3.

The inner container 1 is formed into a bag shape by blow molding or vacuum molding of a synthetic resin material or the like. Further, the inner container 1 is provided with an injection / pouring port 10 on the upper surface for filling the liquid substance inside and discharging it to the outside. An annular recess 10a is formed on the outer peripheral surface of the pouring / spouting port 10. The injection / spout port 10 can be opened and closed by the cap 4.

The outer container 2 has rigidity by being formed by pressing a plated steel plate or the like. Further, the outer container 2 has an inlet / outlet 20 that is open upward so that the inner container 1 can be housed inside and taken out. As the outer container 2, a used conventional 18-liter can can be used by cutting the upper surface (the surface on which the pouring / spouting port is provided) and cleaning the inner portion.

The lid 3 is for press-molding to cover the inlet / outlet 20 of the outer container 2, and is formed by press molding. As shown in FIG. 3, the periphery of the inlet / outlet 10 of the inner container 1 is covered by the lid 3. It has an opening 30 that is fixed to. The opening 30 has an inner diameter substantially equal to the maximum outer diameter of the pouring / spouting port 10 so that the pouring / spouting port 10 can be inserted. Further, the annular recess 10a of the pouring / pouring port 10 is caulked. An annular convex portion 30a that is in close contact with is projected upward. The annular convex portion 30a is formed in the concave portion 30b, and is formed so that the upper end of the pouring / spouting port 10 does not project above the upper end of the lid 3 when it is brought into close contact with the annular concave portion 10a by caulking. This makes it possible to stack containers. It should be noted that the lid body 3 indicated by a chain double-dashed line in FIG. 1 shows the lid body 3 in a state of being fixed to the inner container 1.

The container configured as described above is assembled as follows.

First, the injection / pouring port 10 of the inner container 1 is inserted into the opening 30 of the lid 3, and the annular projection 30a of the opening 30 is caulked with a tool to form the annular projection 30a. Is brought into close contact with the annular recess 10a of the injection / pouring port 10. As a result, the inner container 1 and the lid 3 are integrally fixed.

Next, the inner container 1 and the lid body 3 integrated as described above are mounted on the outer container 2, and then a liquid substance is filled into the inner container 1 through the pouring / spouting port 10. .

When the filling is completed, the injection / spout port 10 is closed with the cap 4. Then, a binding band 5 is placed around the outer container 2 and the lid 3 so that the lid 3 and the inner container 1 do not fall off from the outer container 2.

When using the container, the cap 4 is opened and the liquid substance is discharged to the outside through the injection / pouring port 10.

When all the liquid substances are discharged to the outside and the container is used, the binding band 5 is removed to separate the lid 3 and the inner container 1 from the outer container 2, and the lid 3 and the inner container 1 are separated. Is disposed of, and a new integrated lid 3 and inner container 1 are attached to the outer container 2. After that, the inner container 1 is filled with a liquid by the same method as described above, and then used.

As described above, according to this embodiment, the inner container 1 and the lid 3 are integrally attached to and detached from the outer container 2. Therefore, when the liquid substance filled in the inner container 1 is completely discharged to the outside through the pouring / spouting port 10, the inner container 1 and the lid 3 are separated from the outer container 2 and the inner container 1 is removed. 1 and the lid 3 are discarded, and a new inner container 1 and lid 3 are attached to the outer container 2, and a liquid substance is filled into the inner container 1 through the injection / pouring port 10. As a result, since the liquid substance does not adhere and remain on the inner surface of the outer container 2, the outer container 2 can be reused as it is, which can contribute to resource saving. Further, as the outer container 2, a conventional 18 liter can whose upper surface is cut off and whose inner surface is cleaned can be used, which can further contribute to resource saving. Moreover, the inner container 1 and the lid 3 can be integrally fixed to each other by a simple caulking process using a normal tool. In order to fix the lid 3 to the outer container 2, an adhesive tape may be used instead of the method using the binding band 5 described above. In addition, since the inner container is in direct contact with the liquid material, it has excellent acid resistance and alkali resistance, depending on the chemical properties of the liquid material. desirable.
