[Prior art and its problems]

 This type of container is generally referred to as a ball mill, a pot mill, a vibration mill, a planetary mill, etc. depending on its form. In principle, small particles such as beads, balls, etc., or a stirring medium composed of a combination of these is enclosed in a wear-resistant container such as ceramics, and the container is tumbled or vibrated by an external drive source. The materials inside the container are agitated, and mixed, crushed, dispersed, and the like. Since the stirring mill container used for this is required to have wear resistance, it is formed of a hard material such as metal, resin, or ceramics. In addition, it is necessary to securely seal the opening so that the material inside does not leak during rolling or the like. From the viewpoint of wear resistance, it is desirable to use ceramics, and the following sealing structure for the opening has been conventionally used for this.

In the structure shown in FIG. 6, a hole is vertically formed in the periphery of the opening of the container body 101, and a bolt 102 is inserted into the hole and bonded. The lid that closes the opening is provided with a notch for inserting a bolt, and a wing nut 102 is fastened with a washer sandwiched between the lid closed. A sealing ring 105 is interposed between the container body and the lid, and a nut 104 is fastened to provide a seal. As another form, in the one shown in FIG. 7, the outer peripheral surface of the container body 201 is covered with a metal case 202, a pair of projecting pieces 203 is provided at the upper end of the metal case, and a supporting rod 204 is provided between these projecting pieces 203. It is constructed such that a butterfly head bolt 206 is screwed into the center of the support rod, the lid 205 is pressed against the container body, and a sealing ring 207 between the lid and the container body seals.

In the structure shown in FIG. 6, it is necessary to make holes for bolts in the peripheral edge of the container opening, and especially when the container is made of ceramics, it is necessary to make holes before firing. However, there is a problem that the holes may penetrate when the holes are made. Also, the adhesive strength of the bolt in the hole was weak, and durability was lacking. On the other hand, the one shown in FIG. 7 has no problem in terms of strength, but it has a drawback that the whole case is heavy and the volume is large because the metal case is used.

An object of the present invention is to solve the above conventional problems and provide a stirring mill container which is easy to manufacture and has excellent durability.

In this example, the bolt 4 and the butterfly nut 5 form a fastener for the lid 2. This container is connected to a drive source having a rotating body or a vibrating body in a state in which a material to be stirred for crushing, dispersing or mixing and a stirring medium such as beads, balls, or liquid are enclosed to perform stirring operation. To do. In this example, the height of the container body 1 is 160 mm, the outer diameter is 164 mm, and the diameter of the opening is 94 mm. The wall thickness of the container body and the lid is 7 mm. The metal ring 3 has an outer diameter of 140 mm, a width of 20 mm, and a thickness of 4 mm.

FIG. 2 shows an example of a stirring mill container which is placed and rotated on two parallel rotating rollers. This container is larger than the example of FIG. 1, and a metal ring 3 is adhered to the peripheral edge of an opening provided on the end surface of the cylindrical container body 1. A bolt 4 is erected on the metal ring 3 in the same manner as in FIG. 1, and a lid 2 having a notch portion through which the bolt is inserted is attached. A wing nut 5 is fastened from above the lid, and a sealing ring 6 between the lid 2 and the container body 1 forms a seal inside the metal ring 3. In this container, an air hole 10 is provided on the end face opposite to the material inlet / outlet opening. The air holes are for facilitating material removal. In this example, a metal ring 13 is also adhered to the periphery of the air hole 10, a bolt 14 is planted in the metal ring, and a lid 12 having a notch portion through which the bolt is inserted is attached. A wing nut 15 is fastened from above the lid 12, and a sealing ring 16 interposed between the lid 12 and the container body 1 forms a seal.

As shown in FIG. 3, metal rings 20 are fitted on both ends of a cylindrical container body 1, and the metal rings 20 are supported and rotated by two parallel rotating rollers. In this example, both the opening and the air hole for material input and output are provided on the peripheral surface of the container body. Therefore, the metal ring 3 bonded to the peripheral edge of the opening has a flat upper surface and a bottom surface that is a concave curved surface along the peripheral surface of the container body.
