Description

technical field [0001] This invention relates to accessories for electrophotographic equipment or electrostatic recording equipment, in particular toner bottle caps for supplying developing toner to these equipment. Background technique [0002] Because the mouth of a common toner bottle is relatively large, while the toner cartridge has a relatively small inlet, when using a toner bottle to add toner to the toner cartridge, the following methods are generally used: use a funnel-shaped auxiliary tool to add toner to the toner cartridge. Adding carbon powder in this way requires additional auxiliary tools such as a funnel, which causes some inconvenience to the user, and may cause the carbon powder to fly, pollute the air, and be harmful to the health of the operator.

Problems solved by technology

Adding toner in this way requires additional auxiliary tools such as a funnel, which causes some inconvenience to the user, and may cause the toner to fly, pollute the air, and harm the health of the operator.

[0003] There are also toner bottles that directly use a funnel-shaped pointed bottle cap. When in use, directly cut off the top of the pointed bottle cap and add carbon powder to the toner cartridge. It is relatively long, and the top is relatively sharp. The toner bottle cannot be stored in multiple layers. If a flat cover is added to the pointed bottle cap, it will take up too much space.
