[0046] Embodiment: As shown in Figs. 1-22, a replacement packaging container comprises a pen body 10 and a middle bundle core detachably mounted in the pen body 10, the middle bundle core comprising a middle bundle 20, a bead 30 and a screw 40, the bead 30 being used to store cosmetic material, which can be lipstick, eye shadow, lip gloss, lip balm, eyeliner pencil body, sunscreen stick, body perfume or deodorant stick, etc. The middle bundle 20 is axially fixed and circumferentially movable mounted in the pen body 10, the screw 40 is axially fixed and circumferentially movable mounted in the middle bundle 20, and the screw 40 is circumferentially fixedly mounted in the pen body 10, i.e. the pen body 10 can drive the screw 40 to rotate synchronously when the pen body 10 rotates, the bead 30 is mounted in the middle bundle 20, and the bead 30 is screwed to the screw 40, in use, the user rotates the pen body 10, the screw 40 rotates synchronously, under the driving of the screw 40, the bead 30 can move along the axial direction of the middle bundle 20, so as to make the cosmetic material in the bead 30 extend out of the middle bundle 20 for the user to use, or make the cosmetic material in the bead 30 retract into the inside of the middle bundle 20. Fig. 14 shows the state that the bead 30 is completely retracted into the middle bundle 20; Figs. 17 and 18 show the state that the bead 30 is completely rotated out, i.e. the cosmetic material in the bead 30 is completely exposed to the outside of the middle bundle 20.

[0047] The middle bundle core is detachably installed in the pen body. When the cosmetic material in the bead is used up, the old middle bundle core is only needed to be detached and replaced with a new one, and the remaining parts can be reused, thereby reducing the waste of resources and lightening the economic burden of consumers. FIG. 21 and FIG. 22 show the replacement and delivery diagram of the middle bundle core. In the present application, the middle bundle 20 is axially fixed in the pen body 10, and the spiral member 40 is axially fixed in the middle bundle 20, so as to realize the axial fixation between the spiral member 40 and the pen body 10. When the pen body rotates relative to the middle bundle, the spiral member 40 rotates synchronously, but the spiral member will not move in the axial direction with the pen body, so that the spiral member can drive the bead to move axially in the middle bundle, thereby completing the action of extending or retracting the cosmetic material.

[0048] Optionally, the axial fixation between the middle bundle 20 and the pen body 10 is realized through a first clamping mechanism.

[0049] As shown in FIG. 2 and FIG. 3, the first clamping mechanism includes the first clamping groove 21 and the protrusion 13. The outer side wall of the middle bundle 20 is provided with the first clamping groove 21, or the inner side wall of the pen body 10 is extended radially inward to form the protrusion 13, or the inner side wall of the pen body 10 is provided with the first clamping groove 21, and the outer side wall of the middle bundle 20 is extended radially outward to form the protrusion 13. The protrusion 13 is clamped in the first clamping groove 21 to axially fix the middle bundle 20 and the pen body 10.

[0050] In a possible implementation, the inner side wall of the pen body 10 or the outer side wall of the middle bundle 20 is provided with a ring of protrusions 13. In another possible implementation, the inner side wall of the pen body 10 or the outer side wall of the middle bundle 20 is provided with a plurality of protrusions 13 arranged at intervals. As shown in FIG. 8, the outer side wall of the middle bundle 20 is provided with a ring of first clamping grooves 21 along the circumference, and as shown in FIG. 6, the inner side wall of the pen body 10 is provided with a plurality of protrusions 13 arranged at intervals along the circumference, or the outer side wall of the middle bundle 20 is provided with a plurality of protrusions 13 arranged at intervals along the circumference, and the inner side wall of the pen body 10 is provided with a ring of first clamping grooves 21 along the circumference. The distance between adjacent two protrusions 13 is equal. The pen body 10 can rotate relative to the middle bundle 20 when a ring of first clamping grooves 21 is arranged on the pen body 10 or the middle bundle 20. Correspondingly, the middle bundle 20 or the pen body 10 is provided with a plurality of protrusions 13 arranged at intervals, and the protrusions 13 are clamped in the first clamping grooves 21 to axially fix the middle bundle 20 and the pen body 10. When the cosmetic material in the bead 30 is used up, the middle bundle core can be easily pulled out of the pen body, so the disassembly is very convenient.

[0051] Optionally, the axial fixation between the middle bundle 20 and the spiral member 40 is realized through a second clamping mechanism.

[0052] As shown in FIG. 2 and FIG. 3, the second clamping mechanism comprises a second clamping groove 22 and a convex ring 43, the inner side wall of the middle beam 20 is provided with the second clamping groove 22, the outer side wall of the spiral member 40 is extended radially outward to form the convex ring 43, or the inner side wall of the middle beam 20 is extended radially inward to form the convex ring 43, the outer side wall of the spiral member 40 is provided with the second clamping groove 22, and the convex ring 43 is clamped in the second clamping groove 22 to axially fix the middle beam 20 and the spiral member 40.

[0053] In a possible implementation, the outer side wall of the spiral member 40 or the inner side wall of the middle beam 20 is provided with a ring of convex rings 43. As shown in FIG. 2 and FIG. 3, the inner side wall of the middle beam 20 is circumferentially provided with a ring of second clamping grooves 22, as shown in FIG. 11, the outer side wall of the spiral member 40 is circumferentially provided with a ring of convex rings 43, or the inner side wall of the middle beam 20 is circumferentially provided with a ring of convex rings 43, and the outer side wall of the spiral member 40 is circumferentially provided with a ring of second clamping grooves 22. The provision of a ring of second clamping grooves 22 on the middle beam 20 or the spiral member 40 can ensure that the spiral member 40 can rotate relative to the middle beam 20; correspondingly, the provision of a ring of convex rings 43 on the spiral member 40 or the middle beam 20 can ensure that the spiral member 40 and the middle beam 20 cannot axially move when the convex ring 43 is clamped in the second clamping groove 22, and the installation stability between the spiral member 40 and the middle beam 20 is improved.

[0054] In another possible implementation, a plurality of convex rings 43 are arranged at intervals on the outer side wall of the spiral member 40 or the inner side wall of the middle beam 20, the distance between two adjacent convex rings 43 is equal, and the spiral member 40 and the middle beam 20 cannot axially move when the convex ring 43 is clamped in the second clamping groove 22.

[0055] As shown in FIG. 1-5, the packaging container further comprises a cap 50, the cap 50 is pluggably sleeved on the pen body 10, as shown in FIG. 7, FIG. 13 and FIG. 15, the outer side wall of the pen body 10 is provided with a first clamping point 11 and a sealing ring 12, the outer side wall of the cap 50 is provided with a second clamping point 51 clamped with the first clamping point 11, and the sealing ring 12 is airtightly attached to the cap 50. As shown in FIG. 12 and FIG. 13, when the cap 50 is sleeved on the pen body 10, the second clamping point 51 is located above the first clamping point 11, and after the user presses the cap 50, as shown in FIG. 14 and FIG. 15, the second clamping point 51 passes the first clamping point 11, and the sealing ring 12 is airtightly attached to the inner side wall of the cap 50, so that the cap 50 and the pen body 10 are airtightly matched, and the mutual clamping of the first clamping point 11 and the second clamping point 51 effectively prevents the cap 50 from being separated.

[0056] As shown in Fig. 6, the bottom of the pen body 10 extends axially towards the inside of the pen body 10 to form a connecting rod 14, and the outer side wall of the connecting rod 14 is formed with a first clamping rib 15 in the axial direction, as shown in Figs. 11 and 16, the inner side wall of the spiral member 40 is formed with a second clamping rib 42 which is engaged with the first clamping rib 15. The first clamping rib 15 and the second clamping rib 42 are engaged with each other to enable the spiral member 40 to rotate with the pen body 10. The connecting rod 14 is provided only with the first clamping rib 15 without other engagement structures, so that the height of the connecting rod 14 can be shortened, and the space occupied by the connecting rod in the pen body is reduced, which is particularly suitable for products with large capacity.

[0057] As shown in Fig. 10, the bead 30 comprises a storage barrel 31 and a transmission rod 32 which are fixedly connected, and the inner side wall of the middle beam 20 extends radially inwardly to form a baffle 23, as shown in Figs. 2 and 9, the baffle 23 is provided with a limiting hole 25, the transmission rod 32 is rotatably inserted into the limiting hole 25, and the transmission rod 32 is screwed with the spiral member 40. The cosmetic material is placed in the storage barrel 31, as shown in Fig. 10, the outer side wall of the transmission rod 32 is provided with an external thread 33, as shown in Figs. 2 and 21, the inner side wall of the spiral member 40 is provided with an internal thread 41 which is matched with the external thread 33, and the shape of the limiting hole 25 is matched with the shape of the transmission rod 32. Optionally, the transmission rod 32 is a non-cylindrical structure, as shown in Fig. 10, the cross section of the transmission rod 32 is a long circular structure, as shown in Fig. 9, the limiting hole 25 is a long circular structure, i.e., the limiting hole 25 limits the circumferential rotation of the bead 30, so that the bead 30 can not rotate with the spiral member 40, but only axially move in the middle beam 20.

[0058] During assembly, the spiral member 40 is installed in the middle beam 20, and the spiral member 40 and the middle beam 20 are axially fixed and circumferentially movable assembled together through the convex ring 43 and the second clamping groove 22, the bead 30 is circumferentially fixed and axially movable installed in the middle beam 20, and the transmission rod 32 of the bead 30 is screwed with the spiral member 40 through the external thread 33 and the internal thread 41, thereby forming the middle beam core shown in Fig. 21, and then the middle beam core is installed in the pen body 10, the middle beam 20 and the pen body 10 are axially fixed and circumferentially movable assembled together through the first clamping groove 21 and the convex block 13, and the spiral member 40 and the pen body 10 are circumferentially fixed through the first clamping rib 15 and the second clamping rib 42. It should be noted that the middle beam core shown in Fig. 21 cannot be used alone without the pen body 10. Since the spiral member 40 is basically or entirely hidden in the inside of the middle beam 20, the user cannot rotate the spiral member 40 while holding the middle beam 20 to move the bead 30 along the axial direction of the middle beam 20. Therefore, the present application can avoid the middle beam core from being mistakenly rotated by the user when the middle beam core is separated from the pen body 10, and the cosmetic cream or other contents are damaged.

[0059] In use, the user rotates the pen body 10, the middle shaft 20 remains stationary, the screw member 40 rotates synchronously, and the screw member 40 drives the beads 30 to move along the axial direction of the middle shaft 20, so as to realize the extension or retraction of the cosmetic material in the beads 30. Since the middle shaft 20 is installed with the pen body 10 through the first clamping slot 21 and the protrusion 13, the user can pull out the middle shaft core from the pen body 10 by force, so as to realize the replacement of the middle shaft core.

[0060] As shown in FIGS. 19 and 20, a ring-shaped slot 24 is arranged at the connection between the inner side wall of the middle shaft 20 and the baffle 23. When the middle shaft 20 is made of a plastic material that is easy to shrink, the design of the ring-shaped slot 24 can reduce the deformation of the middle shaft 20 caused by the shrinkage of the material, so that the outer surface of the middle shaft 20 is smoother, and the aesthetic degree of the middle shaft 20 is increased.

[0061] It should be noted that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
