Abstract

PROBLEM TO BE SOLVED: To provide an ultrasonic welding method for securely welding the parts of cases and to provide a toner case in which at least the upper case and lower case are securely welded by ultrasonic welding. SOLUTION: In the upper case 2 and lower case 3 of the toner case 1, a projection 5 having a flat face is formed on the upper case 2, the face being opposite a face on which a weld rib 4 is formed, a horn is brought into contact with the projection 5, a receiving base is brought into contact with the underneath of the lower case 3. Then, the projection 5 is pressed down by the horn to apply vertical vibration thereto, and thus the upper case 2 and lower case 3 are welded together by the ultrasonic welding method. Therefore, even in case the welded portion of the upper case 2 having the weld rib formed thereon has surface sink, curve, un-uniform thickness, and inclination slightly, the vibration of the horn can be securely transmitted to completely melt the weld rub 4. This ensures welding of the upper case 2 and the lower case 3 and reliably prevents a minute leak of toner.

Description of the Related Art In a container for storing fine particles, for example, a toner case for sealing and storing toner in a toner cartridge or a developing unit of a copying machine or a printer, generally two or more parts are joined together. In many cases, for example, as shown in FIG. 5, in the toner case 100, the upper case 101 and the lower case 102 are joined, and the toner 103 as fine particles is stored inside. In this case, as a method for joining the upper case 101 and the lower case 102, an ultrasonic welding method is mainly used from the viewpoint of productivity and sealing property. In addition, in FIG. 5, a portion indicated by a circle is a welded portion.

あっても発生することがある。That is, an important point for surely performing the welding by the ultrasonic welding method is that the vibration of the horn 111 is reliably transmitted to the welding rib 104 of the upper case 101.
Is to melt the upper case 1 as shown in FIG.
If there is a recess 105 due to a sink mark or the like on the surface opposite to the welding rib 104 of No. 01, the vibration of the horn 111 causes the welding rib 104
Directly, the defective welding occurs at that portion, and fine gaps are formed, or the strength is insufficient and peeling easily occurs, which causes toner leakage. Further, as shown in FIG. 7, the pedestal 110 of the lower case 102
The same phenomenon occurs when the concave portion 106 due to sink marks is present on the surface contacting with, causing toner leakage. Such defective welding may occur even when the depth d1 of the recess 105 and the depth d2 of the recess 106 are only 0.02 to 0.05 mm.

Even if the lower case 102 has a slope 107 due to a molding defect such as warpage or uneven thickness, the vibration of the horn 111 is not directly transmitted to the welding ribs 104, which causes welding defects.

害となることが多く、改良の必要性が高まっている。[0007] In particular, as the fine particles contained in the container, for example, the particle diameter of the toner has become as small as several μm, there is a slight gap in the joining between the upper case 101 and the lower case 102. However, since toner leakage occurs, reliable welding is an important issue.
In addition, the shapes of the upper case 101 and the lower case 102, which are the molded parts constituting the toner case 100, are also space-saving
Since the shape tends to be complicated due to the demand for multi-functionality, the possibility of forming defects (warping, sinking, burrs, etc.) increases, and it becomes an obstacle when performing ultrasonic welding. However, the need for improvement is increasing.
