Apparatus for feeding toner to a copying machine

An apparatus for supplying toner is known, for example, from EP-B-152 415. This known device consists of a bottle with aufgesiegelter on the bottle neck film. The film is cut when inserting the bottle into a filler neck over part of the circumference, so that the contents of the bottle poured over the filler neck into a reservoir of the copying machine.

The present invention has for its object to form a device of the type mentioned in such a way that it can be closed before removing it from the copying machine, so that contamination by remaining toner residues in the container can be avoided. This object is achieved by the feature combination of the claims.

Hereinafter, an embodiment of the invention will be explained with reference to the drawings. It shows:

Sections along the lines III-III and IV-IV in Figure 2.

The device consists of a bottle-shaped container 1, on the neck 2, a closure head 3 is screwed, a closure 4 and a flat seal 5 inserted between the head 3 and 4 closure and a sealing ring 6, which seals the head 3 against the container 1. The head 3 has a container-1 facing, roof-shaped elevation 10, which forms a funnel, and two diametrically opposite approximately

Quarter-circle-shaped openings 11 and three extending over slightly more than 90 ° in the circumferential direction, arranged in a common radial plane slots 12th

The seal 5 and an end wall 13 of the closure 4 also have two diametrically opposite openings 14, 15 of the same outline shape as the opening 11 but somewhat larger dimensions. The disc 5 is made of abrasion-resistant and lubricious foam rubber and is glued to the wall 13. From the shutter 4 are above three evenly distributed over the circumference of the cam 16 from whose top is tapered wedge-shaped. The cams 16 are engaged in the slots 12. The lower, plate-shaped foot 20 of the closure 4 has one of four drawn, standing F. color coding cam 21st The relevant cam 21 is formed by means of inserts in the injection mold on the closure 4. The cams 21 ensure that the device can only be inserted on the appropriate opening for the relevant color on the copying machine. On one side of the foot 20 is a locking cam 22 from. On the opposite side, a slider 23 is used for securing the device in the copying machine. The slider 23 consists of an inserted into a rectangular opening 24, cuboid slide member 25 with a protruding latch 26 and an actuating member 27 which inserted through a slot 28 in the foot 20 and with two hook-shaped, resilient tongues 29 in a corresponding opening 30th of the part 25 is engaged. Thus, the slider 23 is held inextricably in the foot 20. The part 27 projects beyond the top 31 of the foot.

The emptying of the toner into the machine via a rotation of the container 1 by 90 °, so that the openings 11, 14, 15 are aligned. Before removing the device from the machine, the container 1 is rotated back to the starting position. The two rotational positions are defined by stopping the cam 16 at the ends of the slots 12. The device allows easy handling and sealing prior to removal from the machine. As a result, the pollution by residual toner can be avoided.
