[0046] Example: Figure 1-22 As shown, a replaceable packaging container includes a pen body 10 and a middle bundle core detachably installed in the pen body 10, the middle bundle core includes a middle bundle 20, beads 30 and a spiral member 40, the beads 30 are used to store cosmetic materials, and the cosmetic materials can be lipstick, eye shadow, lip gloss, lip balm, eyeliner paste, sunscreen stick, body perfume or deodorant stick, etc. The middle bundle 20 is axially fixed and circumferentially movably installed in the pen body 10, the spiral member 40 is axially fixed and circumferentially movably installed in the middle bundle 20, and the spiral member 40 is circumferentially fixedly installed in the pen body 10, that is, when the pen body 10 rotates, it can drive the spiral member 40 to rotate synchronously, the bead 30 is installed in the middle bundle 20, and the bead 30 is screwed to the spiral member 40. When in use, the user rotates the pen body 10, and the spiral member 40 rotates synchronously. Driven by the spiral member 40, the bead 30 can move along the axial direction of the middle bundle 20, so that the cosmetic material in the bead 30 extends out of the middle bundle 20 for the user to use, or the cosmetic material in the bead 30 is retracted into the inside of the middle bundle 20. Fig.14 The bead 30 is shown in a state where it is completely retracted into the middle bundle 20; Fig.17 and Fig.18 The bead 30 is shown in a state where it is completely screwed out, that is, the cosmetic material in the bead 30 is completely exposed to the outside of the middle bundle 20 .

[0047] In the present application, the middle bundle core is detachably installed in the pen body. When the cosmetic material in the beads is used up, it is only necessary to remove the old middle bundle core and replace it with a new one. The remaining parts can be reused, thereby reducing the waste of resources and alleviating the economic burden on consumers. Fig.21 and Fig. 22 The figure shows the replacement shipment 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, thereby realizing 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 does not move axially with the pen body, so that the spiral member can drive the beads to move axially in the middle bundle, thereby completing the action of extending or retracting the cosmetic material.

[0048] Optionally, the middle bundle 20 and the pen body 10 are axially fixed via a first engaging mechanism.

[0049] like Figure 2 and Figure 3 As shown, the first engaging mechanism includes a first engaging groove 21 and a protrusion 13. The outer wall of the middle bundle 20 is provided with the first engaging groove 21, and the inner wall of the pen body 10 extends radially inward to form the protrusion 13. Alternatively, the inner wall of the pen body 10 is provided with the first engaging groove 21, and the outer wall of the middle bundle 20 extends radially outward to form the protrusion 13. The protrusion 13 is engaged in the first engaging groove 21 to axially fix the middle bundle 20 and the pen body 10.

[0050] In one possible embodiment, the inner wall of the pen body 10 or the outer wall of the middle bundle 20 is provided with a circle of protrusions 13. In another possible embodiment, the inner wall of the pen body 10 or the outer wall of the middle bundle 20 is provided with a plurality of protrusions 13 arranged at intervals from each other. Figure 8 As shown, the outer wall of the middle bundle 20 is provided with a circle of first grooves 21 along the circumferential direction. Figure 6 As shown, the inner side wall of the pen body 10 is provided with a plurality of mutually spaced protrusions 13 along the circumferential direction, or the outer side wall of the middle bundle 20 is provided with a plurality of mutually spaced protrusions 13 along the circumferential direction, and the inner side wall of the pen body 10 is provided with a circle of first clamping grooves 21 along the circumferential direction, and the distance between two adjacent protrusions 13 is equal. The pen body 10 or the middle bundle 20 is provided with a circle of first clamping grooves 21, which can ensure that the pen body 10 can rotate circumferentially relative to the middle bundle 20; accordingly, the middle bundle 20 or the pen body 10 is provided with a plurality of spaced protrusions 13, and the protrusions 13 are clamped into the first clamping grooves 21, which play a role in axially fixing the middle bundle 20 and the pen body 10; when the cosmetic material in the beads 30 is used up, it is convenient to pull the middle bundle core out of the pen body, so the disassembly is very convenient.

[0051] Optionally, the middle bundle 20 and the spiral member 40 are axially fixed via a second clamping mechanism.

[0052] like Figure 2 and Figure 3 As shown, the second engaging mechanism includes a second engaging groove 22 and a convex ring 43. The inner side wall of the middle beam 20 is provided with a second engaging groove 22, and the outer side wall of the spiral member 40 extends radially outward to form the convex ring 43. Alternatively, the inner side wall of the middle beam 20 extends radially inward to form the convex ring 43, and the outer side wall of the spiral member 40 is provided with a second engaging groove 22. The convex ring 43 is engaged in the second engaging groove 22 to axially fix the middle beam 20 and the spiral member 40.

[0053] In a possible implementation, the outer wall of the spiral member 40 or the inner wall of the middle bundle 20 is provided with a convex ring 43. Figure 2 and Figure 3 As shown, the inner side wall of the middle beam 20 is provided with a circle of second grooves 22 along the circumferential direction. Fig.11 As shown, the outer wall of the spiral member 40 is provided with a circle of protruding rings 43 along the circumferential direction, or the inner wall of the middle beam 20 is provided with a circle of protruding rings 43 along the circumferential direction, and the outer wall of the spiral member 40 is provided with a circle of second clamping grooves 22 along the circumferential direction. The middle beam 20 or the spiral member 40 is provided with a circle of second clamping grooves 22, which can ensure that the spiral member 40 can rotate relative to the middle beam 20; accordingly, the spiral member 40 or the middle beam 20 is provided with a circle of protruding rings 43, when the protruding rings 43 are clamped in the second clamping grooves 22, it can ensure that the spiral member 40 and the middle beam 20 will not move axially, and improve the installation stability between the spiral member 40 and the middle beam 20.

[0054] In another possible implementation, a plurality of spaced-apart convex rings 43 are provided on the outer wall of the spiral member 40 or the inner wall of the middle bundle 20, and the distance between two adjacent convex rings 43 is equal. When the convex ring 43 is inserted into the second slot 22, it can also ensure that the spiral member 40 and the middle bundle 20 will not move axially.

[0055] like Figure 1-5 As shown, the packaging container also includes a pen cap 50, which is pluggable and sleeved on the pen body 10. Figure 7 , Fig.13 and Fig.15 As shown, the outer wall of the pen body 10 is provided with a first clamping point 11 and a sealing ring 12, the outer wall of the pen cap 50 is provided with a second clamping point 51 that is engaged with the first clamping point 11, and the sealing ring 12 is airtightly attached to the pen cap 50. Fig.12 and Fig.13 As shown in FIG. 1 , when the pen cap 50 is put on the pen body 10, the second clamping point 51 is located above the first clamping point 11. When the user presses the pen cap 50 hard, as shown in FIG. Fig.14 and Fig.15As shown, the second clamping point 51 passes over the first clamping point 11, and the sealing ring 12 is airtightly attached to the inner wall of the pen cap 50, so that the pen cap 50 and the pen body 10 are airtightly matched, and the first clamping point 11 and the second clamping point 51 are engaged with each other to effectively prevent the pen cap 50 from falling off.

[0056] like Figure 6 As shown, the bottom of the pen body 10 extends axially toward the inside of the pen body 10 to form a connecting rod 14, and the outer side wall of the connecting rod 14 forms a first clamp 15 along the axial direction. Fig.11 and Fig.16 As shown, the inner side wall of the spiral member 40 forms a second clamping rib 42 along the axial direction to engage with the first clamping rib 15. The first clamping rib 15 and the second clamping rib 42 that engage with each other make the spiral member 40 rotate along with the rotation of the pen body 10. Only the first clamping rib 15 is provided on the connecting rod 14 without other engaging structures, so the height of the connecting rod 14 can be shortened, and the space occupied by the connecting rod inside the pen body is reduced, which is particularly suitable for large-capacity products.

[0057] like Fig.10 As shown, the bead 30 includes a storage bucket 31 and a transmission rod 32 that are fixedly connected. Figure 2 and Fig. 9 As shown, the inner wall of the middle bundle 20 extends radially inward to form a baffle 23, and a limiting hole 25 is provided in the baffle 23. The transmission rod 32 is inserted into the limiting hole 25 in a non-rotatable manner, and the transmission rod 32 is screwed to the screw member 40. The cosmetic material is placed in the storage barrel 31, as shown in FIG. Fig.10 As shown, the outer wall of the transmission rod 32 is provided with an external thread 33. Figure 2 and Fig.21 As shown, the inner wall of the spiral member 40 is provided with an inner thread 41 matching the outer thread 33, and the shape of the limiting hole 25 matches the shape of the transmission rod 32. Optionally, the transmission rod 32 is a non-cylindrical structure, such as Fig.10 As shown, the cross section of the transmission rod 32 is an oblong structure. Fig. 9 As shown, the limiting hole 25 is an oblong structure, that is, the limiting hole 25 limits the circumferential rotation of the bead 30 , so that it can be ensured that the bead 30 does not rotate with the spiral member 40 and only moves axially in the middle bundle 20 .

[0058] During assembly, the spiral member 40 is installed in the middle bundle 20. The spiral member 40 and the middle bundle 20 are assembled together by the convex ring 43 and the second groove 22 so as to be axially fixed and circumferentially movable. The bead 30 is circumferentially fixed and axially movable in the middle bundle 20. The transmission rod 32 of the bead 30 is screwed with the spiral member 40 by the external thread 33 and the internal thread 41, thereby forming Fig.21The middle bundle core is then installed in the pen body 10, and the middle bundle 20 and the pen body 10 are assembled together axially fixed and circumferentially movable through the first clamping groove 21 and the protrusion 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 Fig.21 The middle bundle core shown cannot be used alone when it is not matched with the pen body 10. Since the spiral member 40 is basically or completely hidden inside the middle bundle 20, the user cannot rotate the spiral member 40 while holding the middle bundle 20 to move the bead 30 along the axial direction of the middle bundle 20. It can be seen that the present application can prevent the middle bundle core from being rotated by the user when it is separated from the pen body 10, thereby damaging the cosmetic cream or other contents.

[0059] When in use, the user rotates the pen body 10, the middle bundle 20 does not move, the spiral member 40 rotates synchronously, and the spiral member 40 drives the bead 30 to move along the axial direction of the middle bundle 20, so as to extend or retract the cosmetic material in the bead 30. Since the middle bundle 20 and the pen body 10 are installed through the first slot 21 and the protrusion 13, the user can pull the middle bundle core out of the pen body 10 by force, so as to replace the middle bundle core.

[0060] like Fig.19 and Fig. 20 As shown, a circle of annular grooves 24 are provided at the connection between the inner side wall of the middle beam 20 and the baffle 23. When the middle beam 20 is made of a plastic material that is easy to shrink, the design of the annular grooves 24 can reduce the deformation of the middle beam 20 caused by the shrinkage of the material, making the outer surface of the middle beam 20 smoother and improving the aesthetics of the middle beam 20.

[0061] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these modifications and improvements are all within the scope of protection of the present application. Therefore, the scope of protection of the patent of the present application shall be subject to the attached claims.
