BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube winding shaft device in a squeezer for products containing tubes such as toothpaste, cosmetics, and adhesives.

[0002]

2. Description of the Related Art Heretofore, a squeezer for a product containing a tube having a tube winding shaft device, in which a slit for inserting a tube tail end which is long in the axial direction is provided on a pipe winding shaft, is known.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the tube winding shaft device in the squeezing device for a tube-containing product described in the above-mentioned prior art, the tail end portion of the tube held in the inserting slit is likely to come off. . An object of the present invention is to provide a novel tube winding shaft device for a squeezer for a product containing a tube, which is devised so as to prevent the tube tail end from coming off.

[0004]

In order to achieve the above object, a tube winding shaft device in a squeezing device for a tube-containing product according to the present invention is provided with a pipe-shaped winding shaft 7. A slit 8 for inserting a tube tail end which is long in the axial direction is opened on the peripheral wall of 7, and a folding edge 23 bent inward is formed on an edge 11 on the front side when rotating in the inserting slit 8. It is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the drawings, the rear portion of the horizontal portion 2 is provided with screws 3 at the upper end of the vertical portion 1 which functions like a pistol stock.
To form a main body 4 having a hook-like shape, and a concave groove 9 is formed on the lateral portion 2 of the main body 4 and a contact portion of the tube 22 is provided at a front end portion of the bottom wall of the concave groove 9. 10 are provided respectively, the state where the pipe-shaped winding shaft 7 is rotatable and cannot be pulled out between the left and right walls 5, 6 of the concave groove portion 9 behind the contact portion 10, and the left end is the concave groove portion 9. The horizontal slit in the state of penetrating outside the left wall 5 of the above, and cut the slit 8 for inserting the tail end of the tube having a length reaching both ends of the left and right walls 5 and 6 on the peripheral wall of the winding shaft 7. The edge 1 which is provided and is the front side when rotating in the inserting slit 8
1 is provided with a folding edge 23 bent in the centripetal direction, and a serration 24 is provided on the tip edge of the folding edge 23. Further, the left end protruding portion 12 of the winding shaft 7 is provided with a portion near the upper end of the trigger member 13. A pawl wheel 14 which is rotatably supported and is integrally attached to a hand-turning knob 25 is non-rotatably fixed to the outer end of the penetrating portion 12 by a cotter 26, and a feed pawl 16 with a spring 15 is attached to an upper end portion of the trigger member 13. , The outer wall of the left wall 5 is supported by the spring 18 with the spring 18 in a state of being engaged with the ratchet wheel 14 in a detachable manner.
Further, a torsion spring 19 that gives a returning force to the trigger member 13 is sandwiched between the trigger member 13 and the vertical portion 1, and a releasing finger rest portion 20 is provided at the base end of the feed claw 16, and The contact portion 2 that is pressed down together with the base end of the lever 18 when the unlocking finger rest portion 20 is pressed to bring the lever 18 into the released state.
1 are provided respectively.

[0006]

In operation, first, the tail end of the tube 22 is inserted into the tube inserting slit 8 and, in this state, the vertical portion 1 of the main body 4 and the trigger member 13 are squeezed with one hand. By repeating the operation and the releasing operation, the ratchet wheel 14 and the winding shaft 7 are rotated by the feed claw 16, and the tail end portion of the tube 22 is bent at the start of the winding shaft 7 as shown by the phantom line in FIG. The tip end of the edge 23 and the edge 27 on the rear side when engaging in the insertion slit 8 are engaged with each other so as not to come off, and the tail end portion of the tube 20 is gradually attached to the winding shaft 7. The tube 22 is wound around, and the winding operation such as the squeezing operation and the releasing operation are repeatedly performed as necessary to increase the winding amount, so that the contents are put in the tube 22.
You can push it toward your mouth.

[0007]

The tube winding shaft device in the squeezing device for a tube-containing product according to the present invention comprises a pipe-shaped winding shaft 7, and a tube tail end which is long in the axial direction is sandwiched between peripheral walls of the winding shaft 7. Since the insertion slit 8 is opened and the edge 11 on the front side when rotating in the insertion slit 8 is provided with the bent edge 23 bent inward, in the above operation As described above, when the winding shaft 7 starts to rotate, as shown in FIG.
As shown by the phantom line, the tail end of the tube 22 engages with the tip of the folded edge 23 and the edge 27 on the rear side when the insertion slit 8 rotates so that it does not come off. It has a remarkable effect of completely achieving the intended purpose.
