Abstract

An ejection device (11) has an ejection unit (12) having a displacement mechanism with two piston rods (13), a receptacle unit (32) including receptacle (34) for a container (33), a head part for limiting the receptacle (34) at one of its ends, a holding device (21) which is arranged on the ejection unit (12) for securing the receptacle unit (32) thereto, and tension members (38) provided on the receptacle unit (32) and which extend along the receptacle (34) and are secured to the head part (35), each tension member (38) having a engageable-from behind section (39) at its end remote of the head part, the holding device (21) having locking elements which can engage the engageable-from behind sections (39) of the tension members (38) to lock the receptacle unit (32) with the ejection unit (12).

Claims

1. An ejection device, comprising an ejection unit (12) including a displacement mechanism having at least one piston rod (13);

receiving means (32) including a receptacle (34) for receiving a container (33) ejectable with the at least one piston rod (13), a head part (35) for limiting the receptacle (34) at one end (36) thereof, and tensioning members (38) extending along the receptacle (34), secured to the head part (35), and each provided, at an end thereof remote from the head part (35), with an engageable-from behind section (39); and

a holding device (21) mounted on the ejection unit (12) for releasably securing the receiving means (32) to the ejection unit (12), the holding device (21) having locking means engageable with the engageable-from behind sections (39) of the tensioning members (38) for locking the receiving unit (32) with the ejection unit (12).

2. An ejection device according to claim 1, wherein the engageable-from behind section (39) of each of the tensioning members (38) has an eyelet (40) having an engageable-from behind opening, and the locking means of the holding device (21) comprises locking hooks (22) each having a locking section (24) and pivotable about a pivot axis (23) into a respective engageable-from behind opening of a respective eyelet (40) for locking the receiving unit (32) with the ejection unit (12).

3. An ejection device according to claim 2, wherein each of the locking hooks (23) has a guide inclination (25) and each is spring-biased in a locking position thereof.

4. An ejection device according to claim 1, wherein the holding device (21) has an actuation member (26) acting on the locking means for unlocking of the receiving unit (32) from the ejection unit (12).

5. An ejection device according to claim 4, wherein the actuation member (26) has a transmitting member (28) having transmitting surfaces that can be brought in abutment with the locking means.

6. An ejection device according to claim 4, wherein the actuation member (26) is spring-biased.
