The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 4, the axial direction of the core 10 is the longitudinal direction, a is the top end, and B is the bottom end, unless otherwise specified.

As shown in FIGS. 1-5, one embodiment of the present application provides a packing tube 1 including a core 10 and a base 60. The middle bunch core 10 comprises a spiral 20, a fork 30 and beads 40 which are all cylindrical and coaxially sleeved together, wherein the spiral 20 is sleeved outside the fork 30, the inner wall of the spiral 20 is provided with a spiral groove 21, the side wall of the fork 30 is provided with a guide groove 31 arranged along the axial direction, the beads 40 are used for bearing cosmetics and are positioned inside the fork 30, the outer wall of the spiral 20 is provided with a protrusion 41 which penetrates through the guide groove 31 and is matched with the spiral groove 21, when the spiral 20 rotates relative to the fork 30, the beads 40 can be driven to move up and down along the axial direction, so that the cosmetics extend out of or retract into the middle bunch core 10, compared with the prior art, the middle bunch core is not arranged, the fork 30 is integrally positioned inside the spiral 20, and the spiral 20 is not only a functional component but also an ornamental component. The cosmetic is generally lipstick, etc.

Considering the environmental protection, the factor of being convenient for to retrieve, spiral 20, fork 30 and pearl 40 are the same, can select according to actual conditions, and the material that this application adopted is PET.

The specific fit between the prongs 30 and the beads 40 can be made using known techniques. The guide groove 31 is opened on the side wall of the fork 30 in the axial direction, and the protrusion 41 passes through the guide groove 31 so that the guide groove 31 restricts the rotation of the bead 40 and the bead 40 can only slide in the axial direction along the guide groove 31. When the screw 20 rotates relative to the fork 30, the spiral groove 21 cooperates with the guide groove 31 to drive the beads 40 to slide in the axial direction.

The spiral groove 21 may be one or a plurality of parallel grooves. Preferably, at least two spiral grooves 21 are provided, and the spiral grooves are arranged at even intervals, so that the guide grooves 31 and the protrusions 41 are arranged at positions corresponding to the spiral grooves 21, so that the beads 40 can simultaneously slide in a multi-angle driving manner, and the movement stability is high.

In some embodiments, the guide groove 31 has two bent positioning regions 36 at two ends, and when the beads 40 slide to the extreme position, the guide groove 31 is located in the positioning region 36 at the corresponding end. The positioning section 36 is provided on the outer wall of the fork 30 at the upper and lower ends of the guide groove 31, and the positioning section 36 extends in the circumferential direction of the fork 30 to allow the beads 40 to stay at the highest or lowest position.

In one embodiment, the middle core 10 includes a connecting seat 50 connected to the bottom of the fork 30, the bottom of the fork 30 is provided with a central hole, and the inside of the connecting seat 50 is provided with a first protruding pillar 54 inserted into the central hole of the fork 30. In order to limit the axial movement of the two, the outer circumference of the first protruding pillar 54 is provided with an annular groove 55, and correspondingly, the central hole is circumferentially provided with a third protruding ring 35 which is matched with the annular groove 55. In order to make the first protruding pillar 54 have a certain elasticity, the first protruding pillar 54 is a hollow structure, and the end portion of the first protruding pillar 54 has a chamfer and a notch, so that the first protruding pillar 54 can be conveniently inserted into the central hole.

As shown in fig. 4, the bottom end surface of the connecting seat 50 has a groove 51, the inner side wall of the groove 51 has a locking groove 52, and the bottom surface of the groove 51 is provided with a positioning hole 53. In the present application, the positioning hole 53 is a-shaped, although the positioning hole 53 is non-circular, and the other shapes have no specific requirement, and can be specifically set according to actual situations, such as a quadrangle, an octagon, a heart, and the like. In addition, the positioning hole 53 may be a through hole or a blind hole. The coupling socket 50 is located inside the screw 20 in consideration of the overall aesthetic appearance.

In one embodiment, as shown in fig. 1, the outer wall of the fork 30 has a first convex ring 32 and a second convex ring 33 for limiting the axial movement of the screw 20, the first convex ring 32 is disposed at the top end of the fork 30, and the second convex ring 33 is disposed at the bottom end of the fork 30; the inner wall of the spiral 20 has a first stop step 22 cooperating with a first male ring 32 and a second stop step 23 cooperating with a second male ring 33. For ease of assembly, the top end of the first male ring 32 is chamfered.

When the screw 20 is specifically assembled with the fork 30, the bottom end of the screw 20 is screwed into the top end of the fork 30, when the second limit step 23 of the screw 20 abuts against the first convex ring 32 of the fork 30, the screw 20 and the fork 30 can be screwed continuously until the first convex ring 32 abuts against the first limit step 22 due to the effect of the chamfer on the first convex ring 32 by using a small force, and at the moment, the second convex ring 33 abuts against the second limit step 23 to be buckled, so that the axial movement of the screw 20 and the fork 30 is limited.

In an embodiment, the base 60 is inserted into and pulled out from the connecting socket 50, the base 60 includes a circular peripheral wall 61 and a bottom wall 62 for closing an end of the peripheral wall 61, a second protrusion 63 is disposed at a central area of the bottom wall 62 facing one side of the connecting socket 50, a positioning block 64 engaged with the positioning hole 53 is disposed on a top surface of the second protrusion 63, and a top surface of the second protrusion 63 abuts against a bottom surface of the groove 51.

In an embodiment, the bottom wall 62 is provided with elastic pieces 65 surrounding the second protruding columns 63, the elastic pieces 65 may be arranged in a ring shape, or may be arranged at intervals, in this embodiment, preferably, the interval is arranged, and the number of the elastic pieces 65 is set to be 4. In addition, the elastic sheet 65 is provided with a flange 66 which is matched with the clamping groove 52, when the bundling core 10 and the base 60 need to be separated, the friction resistance of the two is increased due to the action of the flange 66, the two can be forcibly separated by using larger force, and therefore unnecessary falling off during transportation or use can be avoided.

As shown in fig. 4, the outer wall of the fork 30 is provided with a ring-shaped spring 34 for increasing the torsion force in consideration of the torsion force in practical use.

This application packing tube 1 adopts and detains the position cooperation and replace traditional glued structure, and is environmental protection more, and well bundle core 10 adopts the same material to make in addition, convenient the recovery.

When the middle binding core 10 is specifically installed, the connecting piece and the fork 30 are pressed by using a jig, then the beads 40 penetrate into the fork 30, finally the beads 40, the fork 30 and the connecting piece are screwed into the spiral 20 by using the jig, and at this time, the middle binding core 10 is assembled.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
