## Abstract

A mixing and dispensing device (1) for preparing and applying an adhesive consisting of at least two components, comprises a syringe body (2) which encloses a substantially cylindrical cavity (3), wherein the cavity (3) is divided into at least two chambers separated from each other by a movable separating element (6), wherein—a first chamber (4) has a first component (13) of the adhesive and—a second chamber (5) has a second component (14) of the adhesive, wherein a flow path (11) between the first chamber (4) and the second chamber (5) can be released by moving the separating element (6).

## Claims

### Claim 1

A device for storing, mixing and dispensing a two component adhesive, the device comprising:
a syringe body having a dispensing end and an opposing sealable end, the syringe body having an inner wall defining a substantially cylindrical cavity, the syringe body having a fluid flow path between the dispensing end and the sealable end, the cavity being fluidly connected to a dispensing opening at the dispensing end;
a piston disposed in the cavity adjacent the sealable end for movement toward the dispensing end by a user;
a separating element disposed within the cavity, the separating element and cavity defining a first chamber between the separating element and dispensing end and a second chamber between the separating element and piston, the separating element movable from a first position between the flow path and piston, through a second position adjacent the flow path to a third position between the flow path and the dispensing end, wherein the first chamber and second chamber are fluidly separated by the separating element in the first position, the first chamber and second chamber are fluidly connected by the flow path when the separating element is adjacent the second position and the first chamber and second chamber are fluidly separated by the separating element in the third position.

### Claim 2 (depends on 1)

The device according to claim 1, wherein the first chamber contains a first component of the two component adhesive and the second chamber contains a second component of the two component adhesive.

### Claim 3 (depends on 1)

The device according to claim 1, wherein the fluid flow path is external to the inner wall of the syringe body.

### Claim 4 (depends on 1)

The device according to claim 1, wherein the fluid flow path is defined by a channel in the inner wall of the syringe body.

### Claim 5 (depends on 1)

The device according to claim 1, wherein the fluid flow path is formed in an outward bulge of the syringe body.

### Claim 6 (depends on 1)

The device according to claim 1, wherein movement of the piston toward the dispensing end moves the separating element from the first position towards the third position.

### Claim 7 (depends on 1)

The device according to claim 1, wherein the first chamber contains a liquid first component of the two component adhesive having a first color and the second chamber contains a liquid second component of the two component adhesive having a second color.

### Claim 8 (depends on 1)

The device according to claim 1, further comprising a mixing device fluidly connected to the dispensing opening.

### Claim 9 (depends on 1)

The device according to claim 1, further comprising a stopper for fluidly sealing the dispensing opening.

### Claim 10 (depends on 1)

The device according to claim 1, containing a two component anaerobically curing adhesive.

### Claim 11 (depends on 1)

The device according to claim 1, containing a two component methyl methacrylate adhesive.

### Claim 12 (depends on 1)

The device according to claim 1, having a singular syringe body.

### Claim 13 (depends on 1)

A method for preparing a two part adhesive; comprising:
providing the device according to claim 1, wherein the first chamber contains a first component of the two component adhesive and the second chamber contains a second component of the two component adhesive;
moving the separating element from the first position to the second position to fluidly connect the first chamber and the second chamber; and
mixing the second component of the two component adhesive with the first component of the two component adhesive in the first chamber.

### Claim 14 (depends on 13)

The method of claim 13, further comprising the step of moving the piston toward the dispensing end.

### Claim 15 (depends on 13)

The method of claim 13, further comprising the step of moving the piston toward the dispensing end to displace the separating element from the first position toward the second position.

### Claim 16 (depends on 13)

The method of claim 13, further comprising the step of moving the piston toward the dispensing end to displace the separating element from the first position toward the second position and discharge mixed two component adhesive from the dispensing opening.
