Abstract

A discharge device for discharging a product from a tube having a delivery outlet and a deformable wall. The discharge device according to the invention comprises a housing with a chamber that has a chamber opening and in which the tube is accommodated. A movable stopper is arranged inside the tube and is placed at the end opposite the delivery outlet and closes this end of the tube. An advancing member can be connected to the stopper and is displaceable inside the tube in the direction of the delivery outlet for discharging the fluid product from the tube.

Claims

1. A discharge device for discharging a fluid product from at least one first container, comprising:

a first container in the form of a tube with a dispensing opening and a deformable wall;

a movable stopper arranged in the tube, said stopper being arranged at the end opposite the dispensing opening and closing said end of the tube;

a housing having at least one first chamber which has a first chamber opening and in which the first container is accommodated; and

a movable first advancing member for discharging the product,

the first advancing member is being adapted to be joined to the stopper and being movable within the tube in the direction of the dispensing opening in order to discharge the fluid product from the tube.

2. The discharge device as claimed in claim 1, wherein the housing is designed to be grasped between the fingers of a hand of a user, and wherein an actuating surface is formed on the first advancing member, said actuating surface being arranged in such a manner that it can be actuated with the thumb of the same hand with which the housing is grasped, in order to manually advance the first advancing member to discharge the product.

3. The discharge device as claimed in claim 1, wherein the dispensing opening is closed with a pierceable or severable covering.

4. The discharge device as claimed in claim 3, wherein an external thread which surrounds the dispensing opening is formed on the tube.

5. The discharge device as claimed in claim 1, wherein the discharge device is designed as a multiple syringe which has at least one second chamber with a second chamber opening, a second product which is accommodated in the second chamber and a second advancing member which is arranged movably in the second chamber, the first and the second advancing members being connected to each other at a rear end facing away from the first and second chamber opening.

6. The discharge device as claimed in claim 5,

wherein the dispensing opening of the tube is closed by a pierceable covering,

wherein, in the discharge device, an opening device which is displaceable relative to the tube is provided, with a puncturing element for piercing the covering,

wherein the tube is arranged movably in the first chamber of the discharge device in such a manner that the puncturing element pierces the covering upon movement of the tube in the direction of the first dispensing opening,

and wherein the first and the second advancing member are dimensioned in such a manner that, upon joint advancing of the advancing members, the first advancing member moves the tube in the direction of the first dispensing opening, and as a result, the puncturing element pierces the covering of the tube before the second advancing member ejects the second product from the second chamber.

7. The discharge device as claimed in claim 1, wherein a connecting device is provided, the connecting device connecting the first chamber opening to the dispensing opening of the tube.

8. The discharge device as claimed in claim 1, wherein the dispensing opening of the tube is closed by a covering, and an opening device is provided in the discharge device, in order to sever the covering of the dispensing opening.

9. The discharge device as claimed in claim 8, wherein the opening device is arranged displaceably relative to the tube.

10. The discharge device as claimed in claim 8, wherein the opening device comprises a puncturing element for piercing the covering of the dispensing opening of the tube.

11. The discharge device as claimed in claim 8, wherein the tube is mounted movably in the first chamber of the discharge device, and an actuating element is provided for advancing the tube relative to the first chamber in the direction of the first chamber opening.

12. The discharge device as claimed in claim 11, wherein the actuating element for advancing the tube relative to the chamber is provided by the advancing member for advancing the stopper in the tube.

13. The discharge device as claimed in claim 8, wherein the opening device, in a first position, is adapted to be advanced together with the tube relative to the chamber and, in a second position, abuts in the advancing direction against a stop of the chamber, in which case said opening device is stationary relative to the chamber and displaceable relative to the tube.

14. The discharge device as claimed in claim 8, wherein the opening device has an inner passage line which serves as the connecting device.

15. The discharge device as claimed in claim 8, wherein a guide means is provided for guiding the opening device from a first position into a second position relative to the tube, the guide means having a guide element which is adapted to be screwed onto the tube at the end with the covering, and the opening device being arranged on the guide element.
