Method and a device for preparing a mixture of a solid and a liquid component

A method of preparing a mixture of a solid, particulate or powdered first component and a liquid second component so as to provide a paste-like material, said method comprising:

• arranging the first component in a first cylinder, the size of particles of said first component being such that coherent liquid-receiving interstices are defined therebetween;
• arranging the liquid second component in a second cylinder having a closed first end and an opposite second end, a first end of the first cylinder being arranged in the second end of the second cylinder in a piston-like manner and in sealing relation thereto;
• forcing said liquid second component into the first cylinder by relatively moving the first cylinder towards the closed end of the second cylinder while venting the first cylinder at a second end of the first cylinder opposite to said first end thereof, whereby the liquid second component is received in said interstices in said first component thereby mixing said first and second components together, said step of mixing including venting any gaseous material in said first cylinder to the atmosphere during said relative movement thereby to achieve a substantially homogeneous mixture comprising said paste-like material;
• and
• subsequently expelling said mixture of said first component and said liquid second component mixed to form said paste-like material from the first cylinder, said step of expelling comprising forcing said paste-like material toward said closed end of said second cylinder, said closed end of said second cylinder having a discharge orifice disposed therein, through which said paste-like material is discharged.
