<p>The invention relates to a tube key for exuding a product (7) which is packed in a tube (5), comprising a handle (1) which carries two parallel legs (2) which are free at the ends (4) and which are provided on a distance from each other which is 0,25 -0,75 of the average diameter of the legs. At least the two legs (2) are made of a springy material, and the diameter or the average cross section width of the legs (2) is at least twelve times the thickness of the material of the tube (5) for which the tube key is intended to be used. The legs (2) of the tube key preferably are at least twice as long as the average diameter of the tube (5) for which the key is to be used and one of the legs can be formed with means for increasing the hold between the tube and the leg, for instance rifles (19) or a longitudinal slot (11) open at the end opposite the handle. </p> |
