    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.

    (54) TUBE KEY
    one
    The invention relates to tools for chipping and can be used as a key for tubes used to extrude product from them by means of a rotary motion.
    A key for tubes is known, holding the handle and the gripper for tubes made of elastic material l attached to it.
    The disadvantage of this key is that it cannot be removed from the tube without unwinding the latter, since the grip is made in the form of rods connected at the end.
    In addition, the key cannot be used to extrude a product from various types of tubes.
    The purpose of the invention is to improve the usability.
    The goal is achieved by the fact that in a key containing a handle and a tube holder attached to it made of an elastic material, the latter is made in the form of two rods arranged with a gap, and the gap size exceeds
    0,, 75 times the width of the cross section of the rod and at least twelve times the thickness of the material from which 5 tubes are made.
    The length of the rods is at least twice the diameter of the tube.
    The rods have a longitudinal thread.
    Rods in cross section have the shape of a polyhedron.
    In one of the rods made a longitudinal groove.
    The handle consists of two hinged semi-shackles, on one of which an emphasis is made.
    The key can be made of an elastic metal or an elastic glass fiber material, or of a plastic material.
    O In FIG. 1 shows the proposed key in axonometric, general view; in fig. 2 - key type in operation; in fig. - key execution options.

    Claims (3)
    [1]
    The proposed key consists of a handle 1 made of round material and two parallel rods 2 fixed to it with a gap 3, which may have a cut k, one of the rods may have a longitudinal groove 5 and the handle 1 may consist of two pivotally connected poluskob 6, one of which has an emphasis 7. The key works as follows. The end of the tube 8 is inserted into the gap 3 between the rods 2, which is open on the side opposite to the fastening of the handle 1, the shortest distance between the legs should be 0.25 0.75 times the cross-section of the rods and at least 12 times exceed the thickness of the material from which the tube is made. When the handle 1 is rotated, in view of the fact that the legs 2 are made of an elastic material, they are to some extent squeezed together when the tube is squeezed in connection with the pressure from it. In doing so, the tube 7 is twisted around one rod 2 and held in a secured position with your thumb ,. when the key is rotated by the handle 1. Thus, the end of the tube is twisted into an S-shape, first around one rod 2 and then around the other. After that, the end of the tube is clamped between the first rod 2 and the subsequent turn of the tube 8. When the tube is fully extruded and its corresponding twisting around the bars 2, the key is easily released by simply pulling to the side, since the gap 3 between the bars is much larger than the two-layer material of the tube, and also because of the elasticity of the rods and the presence of the last open free ends. FIG. 6 shows an embodiment of a key in which the handle 1 is made of two half-shells 6 interconnected by a hinge 9. In this case, the stop 7 fixed on one of the half-bars 6 serves to ensure the correct distance between the straps 2. The rods 2 can be made a material having a polyhedron in cross section, such as a square or rectangle. For a more tight grip of the tube, the embodiments 1 and the key provide for the implementation of longitudinal rods or the formation of a narrow groove 5 on one of the rods 2 into which the compressed end of the tube can be inserted transversely. In this case, the groove bar 2 should have a larger diameter than the other bar. The key shown in FIG. 6, can also be used to remove screw caps and as a can opener. Using the proposed key will allow to obtain a significant economic effect due to the user friendliness and expansion of its functionality. Claim 1. A key for a tube containing a handle and a grip for tubes made of resilient material attached to it, such that, for ease of use, the grip is made in the form of two spaced rods, the gap size exceeding 0.25-0.75 times the width of the cross section of the rods and at least twelve times the thickness of the material from which the tube is made.

    2. The key according to claim 1, which means that the length of the rods is at least twice the diameter of the tube.
