2. Description of the Related Art Conventionally, containers of irregular shapes such as elliptical or rectangular cross-sectional shapes obtained by processing cylindrical paper tubes have been produced by dividing the cylindrical paper tube of a predetermined diameter into a container 31 and a lid tube 32 and cutting them. Curled parts 33, 33 are formed by a curling machine that curls one end of the etc.
After forming the container cylinder 31 and the lid cylinder 32, the container cylinder 31 and the lid cylinder 32 are processed into a deforming machine having an elliptical or rectangular hot mold part to have an elliptical or rectangular cross section.
In the lid tube 32, a top plate 35 is fitted, and the bottom plate 34 and the top plate 35 are locked to the curled portions 33, 33 to form a bottomed container c having an irregular shape such as an ellipse or a rectangle.
This forms a lid body d with a top plate, and in use, the lid body d is removably fitted into a container c into which food or other stored items are placed.

[Problems to be Solved by the Invention] However, in the conventional irregularly shaped container, the container tube 31 and the lid tube 32 are in a cylindrical state, and one end is curled, and then the shape is transformed into an ellipse or a rectangle by using a deforming machine. After processing, a bottom plate 34 and a top plate 35 are fitted into the cylinder to be supported by the curled parts 33, 33. When the cylinder is cylindrical, the curled parts 33, 33 are uniformly rolled inward. However, when the shape is deformed into an ellipse or a rectangle, the curled portions 33, 33 expand outward in arcuate portions where the curvature becomes large, resulting in an open state, and the connection between the locked bottom plate 34 and top plate 35 is caused. There were problems in that gaps were formed between the two, resulting in a decrease in strength and airtightness, and rattling in the bottom plate 34 or the top plate 35. The present invention aims to solve the above-mentioned conventional problems, and its purpose is to apply adhesive to the inner periphery of the container cylinder and lid cylinder before curling. By gluing the curled end to the inner peripheral surface and then deforming it into an oval or rectangle, it is possible to prevent the curled end from opening, and to prevent the strength and airtightness from decreasing or the bottom plate and the top plate from wobbling due to this opening. It is an object of the present invention to provide a method for manufacturing a container for irregularly-shaped processing and a container for irregularly-shaped processing with no scratching.

One end of the container cylinder and lid cylinder is curled by applying an adhesive, and the curled end is adhered to the inner circumferential end of the cylinder with the adhesive, and then deformed to have a shaped part such as an ellipse or a rectangle. The container is shaped into an oval, rectangle, etc. by a processing means, and a bottom plate that matches the irregular shape is fitted to the container cylinder, and a top plate that matches the irregular shape is fitted to the lid cylinder, and these are locked to the respective curled parts. It is characterized by obtaining a container body and a lid body. In addition, the irregularly-shaped container according to the present invention has a container cylinder and a lid cylinder in which the end of the curled part is adhered to the inner circumferential end with an adhesive and is irregularly shaped into an ellipse, rectangle, etc. than a cylinder. The present invention is characterized in that it consists of a container body and a lid body, in which a bottom plate of a matching shape is fitted into the lid cylinder, and a top plate matching the irregular shape is fitted, and each is locked to the curled portion. Furthermore, in the manufacturing method of the present invention, an adhesive is applied slightly widely to the container and lid tube of the cylindrical paper tube, and this adhesive is used to bond the curled end, the bottom plate of the container, and the top plate of the lid tube. Sometimes I let them do it.

Effects of the Invention As described above, the method for manufacturing a irregularly shaped container according to the present invention includes applying an adhesive to the inner peripheral end of the container of the cylindrical paper tube and the lid of the cylindrical paper tube. One end of the cylinder and the lid cylinder is curled, and the curled end is adhered to the inner peripheral end of the cylinder with the adhesive, and then shaped into an ellipse, rectangle, etc. by a deforming means having an ellipse, rectangle, etc. mold part. A container and a lid are obtained by machining the container into an irregular shape, fitting a bottom plate with a shape that matches the irregular shape into the container cylinder, and fitting a top plate with a shape that matches the irregular shape into the lid tube, and locking them to the respective curled parts. In addition, the shaped container made by this method is made by bonding the end of the curled part to the inner circumferential end with an adhesive, and forming a container and a lid barrel which are shaped into an oval, rectangle, etc. from a cylinder. Since the lid cylinder is composed of a container body and a lid body, each of which is fitted with a bottom plate that matches the irregular shape and a top plate that matches the irregular shape, and which are respectively locked to the curled portions, the curled portions that support the bottom plate and the top plate are The ends are securely attached with adhesive, so even if the cylindrical shape is transformed into an ellipse or rectangle and the curled part exhibits a small curvature value, it will not expand outward. , there is no reduction in the strength or airtightness of the container or lid due to the expansion, and a container with high strength and airtightness can be obtained at all times;
This has the unique effect of making the container robust and always in good shape without causing rattling of the bottom plate or top plate. In addition, in the present invention, by applying adhesive in a slightly wide manner and using this adhesive to adhere the curled end, the bottom plate of the container, and the top plate of the lid cylinder, it is possible to increase strength, maintain airtightness, and ensure robustness. There is a practical effect of being able to obtain a specially shaped container.
