The utility model provides a can replace well bundle core's packing tube that uses at present, wherein restraint the knot position cooperation structure that adopts between core and the drain pan relatively more complicated, easy damage, the utility model provides a simply can replace the lipstick packing tube of restrainting the core in, can make well bundle core and base realize quick separation and combine.

As shown in fig. 1-3, the present application is a packing tube capable of replacing a middle sleeve, and the packing tube includes a middle bundle core 3, a base and a top cover, wherein the top cover and the base are respectively connected to the middle bundle core 3, the top cover is inserted into and matched with the middle bundle core 3, the base is fixedly connected to the middle bundle core 3, and the base and the top cover surround to accommodate the middle bundle core 3.

As shown in fig. 1 to 3, the base includes an outsole 6, an insole 5 and a middle sleeve 4 fixedly connected to the middle core 3, as shown in fig. 6, the sidewall of the insole 5 is provided with a spiral guide groove 52 having a start end and a stop end, the middle sleeve 4 has a protrusion 44 extending into the guide groove 52 and slidably engaged therewith, and when the middle sleeve 4 rotates relative to the insole 5, the protrusion 44 slides along the guide groove 52, so that the middle sleeve 4 can extend into or be removed from the insole 5.

In order to prevent the protrusion 44 from being separated from the guide groove 52, a limit bump 54 for limiting the movement of the protrusion 44 to the starting end is further disposed near the terminating end of the guide groove 52, and the interference of the limit bump 54 with the middle sleeve 4 determines the blocking force of the limit bump 54.

In one embodiment, the through hole 53 is formed right below the position-limiting protruding point 54 and above the protruding ring 51, so that the position-limiting protruding point 54 has certain elasticity.

In one embodiment, the initial end of the guide groove 52 is located at the top of the insole 5 and is open to facilitate the protrusion 44 entering the guide groove 52.

In one embodiment, the terminating end is located above the protruding ring 51 and is disposed horizontally for receiving the protrusion 44 of the middle sleeve 4, so as to conveniently dispose the position-limiting protrusion 54.

In order to keep the structure stable, in one embodiment, the number of the guide grooves 52 is 2, and the number of the corresponding protrusions 44 is two, and the guide grooves are symmetrically arranged.

The outer sole 6 is an aluminum piece, internal components are protected through metal rigidity, the inner sole 5 is plastic and has no bottom wall, a convex ring 51 is arranged on the outer wall of the inner sole 5, the inner sole 5 and the outer sole 6 can be fixed in an existing connection mode, for example, an axial limiting structure can adopt the convex ring 51 and an annular groove which are mutually matched, and the inner wall of the outer sole 6 is provided with the annular groove, so that the convex ring 51 and the annular groove are axially fixed.

In one embodiment, a first positioning rib extending along the axial direction is arranged below the inner bottom 5, a second positioning rib extending along the axial direction is arranged on the inner wall of the outer bottom 6, and the first positioning rib and the second positioning rib are circumferentially abutted to each other to realize circumferential limiting.

In one embodiment, the insole 5 and the outsole 6 are fixed by 3M glue, and the protruding ring 51 has a function of preventing the 3M glue from overflowing to the guiding groove 52.

As shown in fig. 4 and 5, in one embodiment, the middle sleeve 4 has an annular shoulder 42, both sides of the annular shoulder 42 abut the top cover and the outsole 6, respectively, and the outer peripheral surface of the annular shoulder 42 is flush with the outer peripheral surfaces of the top cover and the outsole 6. When the cover is not used, the annular convex shoulder 42 of the middle sleeve 4 is exposed on the outer surface, so that the matching of surface process colors can be richer and more diversified, and more customer preferences can be met.

The annular shoulder 42 is provided with projections 41 matching with the top cover, and the projections 41 are evenly distributed, so that the top cover has certain resistance to opening.

In one embodiment, an annular groove 43 is provided below the annular shoulder 42, and a key 45 is provided below the annular groove 43 so as to be fixed to the core bundle 3.

Well bundle core 3 can adopt current structure, for example well bundle core 3 includes the pearl, well festival, spiral and well bundle, the pearl is including the flourishing cream section of thick bamboo that is used for splendid attire lotion, the bottom has the actuating lever that stretches into the spiral, the inner wall of spiral is provided with the guide way, the lateral part of actuating lever has the arch that stretches into spiral and guide way complex, well festival and spiral axial fixity, but can rotate relatively, the center is provided with the through-hole with the actuating lever complex, circumference relatively fixed between through-hole and the guide bar, well bundle and well festival fixed connection, accomodate the tubular structure of pearl wherein.

The bottom of the middle bundle core 3 is provided with a groove 32, an annular bulge 31 is arranged above the groove 32, when the middle bundle core 3 is inserted into the middle sleeve 4, the groove 32 is buckled with the key 45 to realize axial limiting, and the annular bulge 31 enters the annular groove 43 to realize axial positioning.

The top cap comprises an outer cap 1 and an inner cap 2, wherein the tail end part of the inner cap 2 facing the middle bundle core 3 is provided with a first bottom wall 22 extending in the axial direction, the first bottom wall 22 is tightly matched with the outer cap 1 in a fixed mode and abuts against one side of an annular shoulder 42, the periphery of the outer cap 1 is flush with the annular shoulder 42, and the attractiveness is improved.

Be provided with protruding strip 21 and evenly distributed on the periphery wall of inner cup 2, quantity can be 4, and the edge at protruding strip 21 beginning end has chamfer or fillet structure, and when inner cup 2 impeld to enclosing cover 1, chamfer or fillet can play the effect on transition inclined plane. The internal perisporium of inner cup 2 is provided with the ring channel near 3 one side of well bundle core, can with the protruding thing 41 lock of well cover 4, and the internal perisporium top of inner cup 2 is provided with rectangular shape protruding strip, and rectangular shape protruding strip is provided with the transition step near 3 one side of well bundle core, can further support well bundle core 3, prevents that well bundle core 3 from rocking between the top cap unnecessary.

When the middle sleeve 4 is installed, the bulge 44 of the middle sleeve 4 is matched with the guide groove 52 of the inner bottom 5, so that the bulge 44 slowly enters the inner bottom 5 in a spiral mode and gradually approaches the limit bump 54 until the limit bump 54 is blocked. Further force is applied at this time, the protrusion 44 goes over the elastic limit bump 54 and is held at the end of the guide groove 52 by the limit bump 54.

When the middle sleeve 4 is disassembled, the bulge 44 is blocked by the limit salient point 54, so that a slight force is required to be applied to relatively rotate the middle sleeve 4 and the inner bottom 5 during the disassembly, the bulge 44 can cross the limit salient point 54 and further move towards the initial end of the guide groove 52, and after the bulge is separated from the initial end of the bottom shell, the middle sleeve 4 and the bottom shell can be pulled away from each other, so that the disassembly is completed.

This application utilizes the spacing bump 54 of elasticity of inner bottom 5 and the protruding 44 interference tight fit of well cover 4, and cover 4 and inner bottom 5's locking in the realization is difficult for losing efficacy for long-time the use, and replacement convenient operation.

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.
