The top plate tooth includes a first state, a second state, and a third state. In the first state, the top plate tooth is located in the lower base channel and the first tooth wall abuts against the lower end of the top plate tooth. At this time, the insert does not contact the fastening device. As the insert rises and reaches the highest point, it is in the third state. The fastening seat protrusion disengages from the outer bottle groove. In the third state, the first tooth wall abuts against the lower end of the top plate tooth and the lower end of the top plate tooth is higher than the top of the second tooth surface. After that, the top plate tooth slides into the second tooth surface and pushes the second tooth wall to move down until the top plate tooth slides to the lower end of the second tooth surface. At this time, it is in the second state.

[0018] In summary, the present invention has the following beneficial effects:

[0019] By pressing the pressing disc upwards, the first spring is compressed, and the first tooth wall abuts against the inclined surface of the top plate tooth, causing the inclined surface of the top plate tooth to exceed the second tooth surface. This allows the top plate tooth to enter the second tooth surface and impact the contact surface. At this moment, the insert abuts against the inner ring of the buckle. The sound of this impact indicates that the buckle protrusion has disengaged from the outer bottle groove, and the replacement part can be removed for use. This replacement method is convenient, intuitive, easy to operate, and reliable. Attached Figure Description

[0050] Reference Figure 15 The inner bottle 71 includes an elliptical inner bottle end face 713 and a neck 712 located at the upper end of the inner bottle end face 713. The upper outer wall of the neck 712 is provided with an external thread 7121, and the lower outer wall of the neck 712 extends outward to form two symmetrical positioning blocks 711. The lower outer wall of the inner bottle 71 is provided with an inner bottle groove 714, and the inner bottle groove 714 is also provided with a groove protrusion 7141.

[0051] Reference Figure 4 , Figure 16 , Figure 17The shoulder sleeve 75 includes a first shoulder sleeve ring 751, a second shoulder sleeve ring 752, and a third shoulder sleeve ring 753, which are spaced apart from the inside to the outside. The first shoulder sleeve ring 751 and the second shoulder sleeve ring 752 are both circular rings, and the third shoulder sleeve ring 753 is an elliptical ring. A circular receiving groove 755 is formed between the first shoulder sleeve ring 751 and the second shoulder sleeve ring 752. Two annular channels 7511 are formed at the upper end of the first shoulder sleeve ring 751. A first protrusion 7512 and a second protrusion 7513 are formed at each annular channel 7511. The width of the annular channel 7511 at the location of the first protrusion 7512 and the second protrusion 7513 is smaller than the width of the annular channels 7511 in other parts. The first shoulder sleeve ring 751 is also provided with a vertical straight channel 7514. The upper end of the straight channel 7514 is connected to one end of the annular channel 7511. The entire straight channel 7514 is connected to the receiving groove 755. Two straight channels 7514, one large and one small, are designed for easy identification and positioning during assembly. The inner wall of the second shoulder collar 752 has an internal thread 7521 that matches the external thread 7121.

The inner wall of the nozzle ring 761 has two nozzle protrusions 762, one large and one small, corresponding one-to-one with the two straight channels 7514. Specifically, one nozzle protrusion 762 consists of two protrusions, making it wider overall, while the other is a single protrusion. The nozzle ring 761 and the receiving groove 755 are vertically aligned. In normal operation, when not in use, the nozzle protrusions 762 are located in the annular channel 7511, specifically at one end of the annular channel 7511 where the first protrusion 7512 is located. Thus, the nozzle protrusions 762 are constrained by the first protrusion 7512, and are positioned without external force. When in use, the nozzle protrusion 762 will not pass the first protrusion 7512, and the nozzle 76 is locked and cannot be pressed down. When it is necessary to press the nozzle 76 to use it, rotate the nozzle 76 so that the nozzle protrusion 762 passes the first protrusion 7512 and then the second protrusion 7513 and comes to the top of the straight channel 7514. At this time, press the nozzle 76, and the nozzle protrusion 762 can be inserted into the straight channel 7514, so that the packaging bottle can be used normally. The second protrusion 7513 plays a positioning role. During the rotation of the nozzle 76, the rotation stops after passing the second protrusion 7513, so that the nozzle protrusion 762 can be aligned with the straight channel 7514 below.

There are two guide heads 53 and two guide channels 43. When the guide head 53 is located at the end of the first channel 431, it is restricted by the second channel protrusion 4331. When the guide head 53 is located at the end of the third channel 433, it is restricted by the second channel protrusion 4331. The rotation angle of the guide head 53 from the end of the first channel 431 to the end of the third channel 433 is 180 degrees. Since the upper base channel 223 clamps the guide head 53, the rotating base 2 can drive the guide head 53 to move along the guide channel 43.

[0058] Reference Figure 13The top plate 6 includes a plate body 62 and a top plate protrusion 61 located at the lower end of the plate body 62. The outer wall of the top plate protrusion 61 is provided with an outwardly protruding protrusion block 611. The top plate protrusion 61 passes through the receiving plate 52 and is inserted into the guide post 5. The top plate protrusion 61 is fastened to the guide post 5 through the protrusion block 611. The protruding part inside the guide post 5 that cooperates with the protrusion block 611 is located above the protrusion block 611. In this way, the protrusion block 611 is not easy to pull out after passing through and can rotate relatively horizontally. The two ends of the plate body 62 are provided with upwardly extending plate body sides 63. The inner side of the plate body side 63 is provided with an inwardly extending side protrusion 631. The side protrusion 631 is also provided with a protrusion notch 6311. The side protrusion 631 is adapted to the inner bottle groove 714. The protrusion notch 6311 is adapted to the groove protrusion 7141. The side protrusion 631 is fastened to the inner bottle groove 714. This way, the replacement part 7 will not fall out when the entire packaging bottle is inverted, and it can be removed together when replacing the replacement part 7.

[0059] Reference Figure 14 , Figure 23 The fastening device 8 is slidably disposed above the positioning block 4. There are two fastening devices 8, distributed at both ends of the elliptical major axis. Each fastening device 8 includes a fastening seat 81 and a second spring 82. The fastening seat 81 includes a fastening seat body 811 and guide posts 812 located on both sides of the fastening seat body 811. The lower end of the fastening seat body 811 forms an outer ring 8112 and an inner ring 8113. The lower ends of both the outer ring 8112 and the inner ring 8113 are inclined and basically symmetrically inclined. An inner groove 8114 is formed between the buckle and the outer side of the upper end of the buckle body 811. A buckle protrusion 8111 is formed on the outer side of the buckle body 811. The buckle protrusion 8111 is fastened to the outer bottle groove 12 so that the replacement part 7 is held above the top plate 6. The buckle 81 includes a buckle shaft 813 located inside it. The second spring 82 is sleeved around the buckle shaft 813. The two ends of the second spring 82 abut against the inner side of the buckle body 811 and the support groove 471, respectively. When the second spring 82 is in a compressed state, the buckle protrusion 8111 is disengaged from the outer bottle groove 12. When the packaging bottle is in normal use, the outer end of the buckle 81 (specifically the buckle outer ring 8112) abuts against the stop point 413. The upper end of the insert 32 is inclined in the same direction as the lower end of the buckle inner ring 8113, so that the two can reliably abut against each other. The guide post 812 slides and engages with the extension channel 461.

[0060] Reference Figures 19-21The pressing device 9 includes a pressing block 91, a pressing toothed disc 92 and a top disc 93. The pressing block 91 includes a pressing disc 911 and a pressing block ring 912 located at the center of the upper end of the pressing disc 911. The outer wall of the pressing block ring 912 is provided with a pressing block protrusion 9121. The pressing toothed disc 92 includes a toothed disc ring 921, a guide block 923, and top teeth 922 circumferentially distributed on the outer side of the upper end of the toothed disc ring 921. The top teeth 922 are located inside the base toothed block 213. The toothed disc ring 921 passes through the central hole 2121 of the disc surface. The lower end of the toothed disc ring 921 abuts against the pressing disc 911. The inner wall of the toothed disc ring 921 is provided with a toothed disc ring protrusion 9211, which matches the pressing block protrusion 9121. The pressing block protrusion 9121 is located above the toothed disc ring protrusion 9211. The pressing block ring 912 is located inside the toothed disc ring 921. The inner diameter of the central hole 2121 of the disc surface is smaller than the outer diameter of the top teeth 922. Figure 25 This allows the pressing toothed disc 92 to hang on the outside of the hole 2121 in the disc surface without falling off.

[0061] The guide block 923 is located outside the top tooth 922. The guide block 923 is located in the lower base channel 214. The top tooth 922 includes an inclined first tooth wall 9221 and a second tooth wall 9222. The upper end of the entire pressing tooth disk 92 is formed by alternating circumferential connections of the first tooth wall 9221 and the second tooth wall 9222.

[0062] The top plate 93 includes a top plate ring 931 and top plate teeth 932 evenly distributed around the outer wall of the top plate ring 931. The top plate ring 931 is located inside the top teeth 922, and the lower ring 34 of the insert block is located inside the top plate ring 931. The lower end face of the top plate teeth 932 forms an inclined top plate tooth slope 9321. The first tooth surface 2131, the second tooth surface 2132, the first tooth wall 9221, and the top plate tooth slope 9321 are inclined in the same direction, that is, their height gradually decreases in the counterclockwise direction. The second tooth wall 9222 is inclined in the opposite direction to the first tooth wall 9221, that is, the height of the second tooth wall 9222 gradually increases in the counterclockwise direction.

[0063] Reference Figure 3 The upper base 22 and the insert plate 31 are connected by a first spring 35, which is located on the periphery of the upper ring 33 of the insert.

[0064] Reference Figure 23This is the first state of the top plate tooth 932. In this state, the packaging bottle can be used normally. Through the force of the first spring 35, the lower end of the insert plate 31 abuts against the upper end of the top plate ring 931, the inclined surface of the top plate tooth 9321 abuts against the first tooth wall 9221, and the lower end of the top tooth 922 abuts against the outer side of the central hole 2121 of the plate. At this time, the lower end of the pressing plate 911 is flush with or slightly higher than the lower end of the lower base 21. The top plate tooth 932 is located in the lower base channel 214, the upper end of the insert 32 does not exceed the upper base 22, and the buckle protrusion 8111 is in a buckling state with the outer bottle groove 12.

[0065] Reference Figure 24 This is the third state of the top plate teeth 932 after pressing the pressing disc 911. At this time, the pressing disc 911 has been pressed upward to the limit position, the upper end surface of the pressing disc 911 is close to the lower base plate surface 212, the first spring 35 is compressed, the first tooth wall 9221 abuts against the top plate tooth inclined surface 9321 and the lowest point of the top plate tooth inclined surface 9321 is higher than the highest point of the second tooth surface 2132, the insert 32 abuts against the inner ring 8113 of the buckle and the insert 32 continues to move upward, the buckle 81 moves horizontally inward, the top surface of the insert 32 extends into the inner groove 8114 of the buckle, the buckle protrusion 8111 disengages from the outer bottle groove 12 and the disengagement distance reaches the maximum.

[0066] After reaching the third state, since the first tooth wall 9221 and the top plate tooth inclined surface 9321 are in inclined engagement, the top plate tooth inclined surface 9321 will rotate into the second tooth surface 2132 under the force of the first spring 35. The top plate tooth inclined surface 9321 and the second tooth surface 2132 are also in inclined engagement. The top plate tooth inclined surface 9321 slides along the second tooth surface 2132. During the sliding process, the top plate tooth 932 will push the second tooth wall 9222, so that the pressing tooth plate 92 and the pressing block 91 slide down together along the lower base channel 214. After that, it enters the second state of the top plate tooth 932.

[0067] Reference Figure 25 In the second state of the top plate tooth 932, the pressing tooth plate 92 and the pressing block 91 have descended to their limit positions. The pressing tooth plate 92 does not contact the top plate 93 at this time. After opening the second tooth wall 9222, the top plate tooth 932 will slide to the limit position of the second tooth surface 2132. The top plate tooth 932 hits the contact surface 2133. At this time, a knocking sound will be heard, indicating that the top plate tooth 932 has reached the expected position and cannot be dislodged. The buckle protrusion 8111 and the outer bottle groove 12 remain dislodged, but the dislodging distance is shorter than that in the third state. At this time, the insert 32 slips off the buckle inner groove 8114, but the top inclined surface of the insert 32 still abuts against the bottom inclined surface of the buckle inner ring 8113.

[0068] In the second state, the base 2, insert block 3, positioning block 4, guide post 5, top plate 6, replacement part 7, fastening device 8 and pressing device 9 can be detached from the bottom of the outer bottle 1.

[0069] A method for replacing cosmetic packaging bottles includes the following steps:

[0070] a. Push the pressing device 9 upward, the first tooth wall 9221 abuts against the top plate tooth inclined surface 9321 upward, the insert 32 moves upward and abuts against the inner ring 8113 of the buckle and the insert 32 continues to move upward, the buckle 81 moves horizontally inward, the buckle protrusion 8111 gradually separates from the outer bottle groove 12 until the lowest point of the top plate tooth inclined surface 9321 is higher than the highest point of the second tooth surface 2132;

[0071] b. The top plate tooth inclined surface 9321 slides into the location of the second tooth surface 2132 until the top plate tooth 932 abuts against the abutment surface 2133, at which point the locking position is reached.

[0072] c. Disconnect the base 2, insert block 3, positioning block 4, guide post 5, top plate 6, replacement part 7, fastening device 8 and pressing device 9 from the bottom of the outer bottle 1.

[0073] After reinstalling the new replacement unit 7, there are two installation methods. One is based on the second state, as described in the following example. Figure 25 At this time, push the pressing block 91 upward, the first tooth wall 9221 abuts against the top plate tooth inclined surface 9321 and moves upward until the lowest point of the top plate tooth inclined surface 9321 is higher than the highest point of the first tooth surface 2131. At this time, the top plate tooth inclined surface 9321 will rotate and slide into the first tooth surface 2131. After sliding along the first tooth surface 2131, the top plate tooth inclined surface 9321 is inserted into the lower base channel 214 and returns to the first state. At this time, the entire bottom of the replacement part 7 can be inserted upward together. During the insertion process, the buckle protrusion 8111 will automatically compress the second spring 82 to avoid and finally buckle into the outer bottle groove 12.

[0074] Another method involves assembling the new replacement part 7 in the second state, inserting it directly, and then pushing the pressing block 91 upwards to perform the same operation after it is in place.
