[0008] The inner core includes a pump head and a bottle body. The inner cavity of the bottle body is used to fill cosmetics. The pump head is connected to one end of the bottle body. The pump head can be communicated with the first opening. A positioning column is provided on the outside of the bottle body. The positioning column can pass through the guide hole and extend into the slide groove. The rotation of the connecting ring can drive the positioning column to move between the locking area and the unlocking area.

[0009] In a feasible implementation, a first limit block is provided on the outer side of the outer cylinder, and a second limit block is provided on the inner side of the connecting ring. The cooperation between the first limit block and the second limit block enables the connecting ring to rotate between a first position and a second position.

Specifically, in the process of connecting the inner core to the outer shell, the connecting ring is rotated so that the slide groove corresponds to the unlocking area, and the inner core is inserted into the outer cylinder, so that the pump head moves toward the first opening and finally communicates with the first opening, so that the cosmetics in the bottle body can be discharged from the first opening by pressing the pump head, and the positioning column passes through the unlocking area of ​​the guide hole and extends into the slide groove. After the connecting ring is rotated again, the slide groove rotates relative to the guide hole, thereby driving the positioning column to move from the unlocking area to the locking area, so that the positioning column is now fixed in the locking area, so that the position of the inner core and the outer cylinder is limited within a certain range, that is, the inner core is installed on the outer shell. After all the cosmetics in the inner bottle are used up, the connecting ring is rotated in the opposite direction, thereby driving the positioning column to move from the locking area to the unlocking area, and the inner core is pulled out of the outer cylinder, and a new inner core can be installed in the outer cylinder.

[0020] In summary, in the cosmetic packaging bottle provided in the present application, the outer shell and the inner core are detachably connected, and the outer shell can be used multiple times, which saves costs, reduces the difficulty of recycling the cosmetic packaging bottle, and reduces waste.

[0042] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0043] First embodiment

[0044] Please refer to Figure 1 - Fig.12 This embodiment provides a cosmetic packaging bottle, which includes an outer shell and an inner core, and the outer shell and the inner core are detachably connected.

[0045] Specifically, the outer shell includes an outer cylinder 1 and a connecting ring 2 . The connecting ring 2 is sleeved on the outer side of the outer cylinder 1 and is rotatably connected to the outer cylinder 1 .

[0046] The inner core includes a pump head 4 and a bottle body 5. The inner cavity of the bottle body 5 is used to fill cosmetics. The pump head 4 is installed at one end of the bottle body 5. The end of the bottle body 5 where the pump head 4 is installed extends into the inner side of the outer tube 1. At least a part of the bottle body 5 extends into the inner side of the outer tube 1. Of course, the entire area of ​​the bottle body 5 can also be extended into the inner side of the outer tube 1.

[0047] A first opening 8 is provided at the first end of the outer tube 1, and a second opening is provided at the opposite second end. The first opening 8 is used for allowing cosmetics to pass through, and the second opening is used for allowing the pump head 4 and the bottle body 5 to pass through. The pump head 4 and the bottle body 5 are inserted into the inner side of the outer tube 1 from the second opening. After the bottle body 5 and the pump head 4 are inserted into place, the pump head 4 is connected to the first opening 8. The pump head 4 can be squeezed to discharge the cosmetics in the bottle body 5 through the first opening 8 for the user to take.

[0048] A guide hole 10 is provided on the side wall of the outer tube 1, and the guide hole 10 has an unlocking area and a locking area 13. A slide groove 14 is provided on the inner wall of the connecting ring 2. When the connecting ring 2 rotates relative to the outer tube 1, the position of the slide groove 14 changes. The rotation of the connecting ring 2 can make the slide groove 14 switch from being relative to the unlocking area to being relative to the locking area 13, or switch from being relative to the locking area 13 to being relative to the unlocking area.

[0049] Preferably, an exhaust hole 6 is provided on the side wall of the outer tube 1 , and the exhaust hole 6 is located at the first end of the outer tube 1 or in an area close to the first end. When the inner core is inserted into the outer tube 1 , the air in the outer tube 1 is discharged through the exhaust hole 6 .

[0050] Further, preferably, the outer cylinder 1 can be made of a transparent material, such as transparent plastic or glass, etc. The transparent outer cylinder 1 allows the user to see the outer side of the inner core through the side wall of the outer cylinder 1. In this way, the product information can be printed on the outer side of the inner core, and the outer cylinder 1 can protect the information printed on the outer side of the inner core to prevent it from being worn.

[0051] In a feasible embodiment, the cosmetic packaging bottle further comprises a top cover 3, which is used to cover one end of the bottle body 5. Specifically, the top cover 3 can cover the first opening 8 to prevent the cosmetics at the first opening 8 from drying out.

[0052] Preferably, if Fig.12As shown, a sealing outer ring 17 and a sealing protrusion 18 are arranged on the inner side of the top cover 3, the sealing outer ring 17 is arranged around the peripheral area of ​​the sealing protrusion 18, and a sealing groove is formed between the sealing outer ring 17 and the sealing protrusion 18. A discharge pipeline 19 is arranged at the first end of the outer cylinder 1, and the outer diameter of the discharge pipeline 19 is smaller than the outer diameter of the main part of the outer cylinder 1. The discharge pipeline 19 extends along the axial direction of the outer cylinder 1, and the first opening 8 is the end surface opening of the discharge pipeline 19. The pump head 4 is connected with the first opening 8 through the discharge pipeline 19. After the top cover 3 is covered on the first end of the outer cylinder 1, the end of the discharge pipeline 19 extends into the sealing groove, and the sealing protrusion 18 extends into the first opening 8 to seal the first opening 8. The sealing outer ring 17 covers the peripheral area of ​​the end surface of the discharge pipeline 19, and the sealing outer ring 17 cooperates with the sealing protrusion 18 to play a radial limiting role for the discharge pipeline 19. Furthermore, the sealing protrusion 18 is a variable diameter structure along the axial direction of the outer tube 1. When it is buckled on the outer tube 1, its outer diameter gradually decreases from one end away from the outer tube 1 to the other end, and its minimum outer diameter is smaller than the diameter of the first opening 8, and its maximum outer diameter is larger than the diameter of the first opening 8. The small end is conducive to the sealing protrusion 18 extending into the first opening 8, and the variable diameter structure is conducive to the sealing protrusion 18 playing a good sealing role for the first opening 8.

[0053] The pump head 4 is connected to one end of the bottle body 5, and the pump head 4 can be communicated with the first opening 8. A positioning column 20 is arranged on the outer side of the bottle body 5, and the positioning column 20 can pass through the guide hole 10 and extend into the slide groove 14. During the rotation of the connecting ring 2, the positioning column 20 is driven to move between the locking area 13 and the unlocking area through the inner wall of the slide groove 14. When the slide groove 14 is opposite to the unlocking area, the positioning column 20 can extend into the slide groove 14 and the unlocking area. When the slide groove 14 is opposite to the locking area 13, the positioning column 20 is confined in the locking area 13.

[0054] like Figure 5 As shown, in a feasible implementation, the unlocking area includes a first section 11 and a second section 12, and both ends of the second section 12 are connected to the locking area 13 and the first section 11 respectively, and the extension direction of the first section 11, the extension direction of the locking area 13 and the extension direction of the slide groove 14 are all parallel to the axial direction of the outer tube 1. The second section 12 is a transition section, so that the positioning column 20 will switch between the unlocking area and the locking area 13 only after the connecting ring 2 is screwed to a certain angle, thereby avoiding the phenomenon of false touch.

[0055] In a feasible embodiment, the second section 12 is an arc section. Of course, in other feasible embodiments, the second end can also be an inclined section.

[0056] like Figure 6 - Fig.11As shown, in a feasible implementation scheme, a first limit block 21 is provided on the outer side of the outer cylinder 1, and a second limit block is provided on the inner side of the connecting ring 2. The cooperation between the first limit block 21 and the second limit block enables the connecting ring 2 to rotate between the first position and the second position. When the connecting ring 2 is in the first position, the slide groove 14 is opposite to the first section 11. When the connecting ring 2 is in the second position, the slide groove 14 is opposite to the locking area 13.

[0057] like Fig. 9 - Fig.11 As shown, the slide groove 14 can be formed by two convex ribs protruding from the inner wall of the connecting ring 2. The two convex ribs are arranged at intervals, and the slide groove 14 is formed between the two convex ribs. One of the convex ribs can be used as a second limit block. Fig.10 and Fig.11 In the embodiment, the first rib 22 is used as the second limit block.

[0058] For ease of naming, the two ribs forming a slide groove 14 are respectively referred to as the first rib 22 and the second rib 23. The slide groove 14 has three surfaces, namely two side surfaces and a bottom surface. The two side surfaces are respectively formed by a surface of the first rib 22 and a surface of the second rib 23, and the bottom surface is located between the two side surfaces.

[0059] Furthermore, if Fig.10 and Fig.11 As shown, the slide groove 14 includes a first groove portion 15 and a second groove portion 16, the first groove portion 15 is connected to the second groove portion 16, and the depth of the first groove portion 15 is greater than the depth of the second groove portion 16, and the transition surface between the bottom surface of the first groove portion 15 and the bottom surface of the second groove portion 16 is an inclined surface, so that the positioning column 20 can move between the two groove portions. When the connecting ring 2 is installed to the second end of the outer cylinder 1, the first groove portion 15 can be opposite to the positioning hole during the rotation process, while the second groove portion 16 cannot be opposite to the positioning hole. In the process of extending the inner core into the outer shell, the positioning column 20 first enters the second groove portion 16, moves along the second groove portion 16 for a certain distance, and then enters the first groove portion 15. Since the first groove portion 15 is opposite to the positioning hole, the positioning column 20 enters the positioning hole at the same time as entering the first groove portion 15. Since the transition section between the first groove portion 15 and the second groove portion 16 is an inclined surface, it is easier for the positioning column 20 to enter the first groove portion 15. After the positioning column 20 enters the first groove portion 15, the inclined surface plays a certain limiting role for the positioning column 20, which can prevent the positioning column 20 from entering the second groove portion 16 from the first groove portion 15 without the action of external force to a certain extent.

[0060] To facilitate squeezing the pump head 4 so that the pump head 4 can pump the cosmetics to the first opening 8, in a feasible embodiment, the first end of the outer tube 1 can be set as a pressable structure, and the first end of the outer tube 1 is pressed to squeeze the pump head 4 located on one side of the first end, so that the pump head 4 pumps the cosmetics to the first opening 8.

[0061] Alternatively, in another feasible implementation, the outer tube 1 is an integrated structure, and the pump head 4 is squeezed by pressing the inner core at the second opening, so that the pump head 4 pumps the cosmetics to the first opening 8 .

[0062] To facilitate pressing the inner core, preferably, the length of the locking area 13 along the axial direction of the outer cylinder 1 is greater than the length of the positioning column 20 along the axial direction of the outer cylinder 1, so that the positioning column 20 can move axially along the outer cylinder 1 within a set range in the locking area 13. The limitation of the locking area 13 on the positioning column 20 allows the positioning column 20 to only move axially along the outer cylinder 1 within the limited range of the locking area 13, that is, the inner core and the outer cylinder 1 are limited within a certain range, and the inner core can move axially within a certain range relative to the outer cylinder 1, that is, the operation of pressing the inner core can be achieved in a locked state. When pressing the inner core, insert a finger from the second opening to push the inner core to move axially relative to the outer cylinder 1, and the positioning column 20 moves within the limited range of the locking area 13.

[0063] The length direction of the locking area 13 is parallel to the axial direction of the outer cylinder 1, and the width direction of the locking area 13 is perpendicular to the length direction. The maximum distance of the positioning column 20 along the length direction of the locking area 13 is X, and the maximum distance of the positioning column 20 along the width direction of the locking area 13 is Y. Preferably, the length of the locking area 13 is greater than X, and the width of the locking area 13 is slightly greater than Y, or in other words, the width of the locking area 13 matches Y, so that the locking area 13 has a limiting effect on the positioning column 20 in the width direction, that is, the positioning column 20 can only move in the locking area 13 along the length direction of the locking area 13, and will not shake in the width direction.

[0064] The positioning post 20 may be a cylinder, a prism or an irregularly shaped cylinder.

[0065] Preferably, the positioning post 20 is a cylinder, and its side surface in contact with the side wall of the locking area 13 is a curved surface, which facilitates the movement of the positioning post 20 relative to the locking area 13. When the positioning post 20 is a cylinder, X and Y are both the outer diameters of the positioning post 20, and X=Y.

[0066] Furthermore, if Figure 2 - Figure 7 As shown, in a preferred embodiment, the guide hole 10 is provided at the second end of the outer tube 1, and the connecting ring 2 is sleeved on the second end of the outer tube 1. Fig.12 As shown, a partial area of ​​the connecting ring 2 is sleeved on the outside of the second end of the outer tube 1, and a partial area is not opposite to the outer tube 1. The hollow chamber surrounded by the partial structure of the connecting ring 2 protruding from the outer tube 1 is used to cover the partial structure of the inner core protruding from the outer tube 1, thereby improving the aesthetics of the cosmetic packaging bottle, preventing the inner core from being pressed accidentally, and protecting the partial structure of the inner core protruding from the outer tube 1.

[0067] In a feasible embodiment, the inner core further includes a bottom cover 7 , which is connected to the other end of the bottle body 5 away from the pump head 4 , and the outer diameter of the bottom cover 7 is larger than the outer diameter of the outer tube 1 and smaller than the inner diameter of the connecting ring 2 .

[0068] In a feasible implementation, the number of guide holes 10, slide grooves 14 and positioning posts 20 are all two, and the two positioning posts 20 are symmetrically arranged on the outer side of the inner core relative to the axis of the inner core. The guide holes 10 and the positioning posts 20 are arranged in a one-to-one correspondence, and the guide holes 10 and the slide grooves 14 are arranged in a one-to-one correspondence, that is, one guide hole 10 and one slide groove 14 are one group, and another guide hole 10 and another slide groove 14 are another group. When one positioning post 20 extends into one group of guide holes 10 and slide grooves 14, the other positioning post 20 extends into another group of guide holes 10 and slide grooves 14. With such an arrangement, when the inner core is pressed, the two relative positioning posts 20 move along their corresponding guide holes 10 respectively, and the guide holes 10 play a limiting role for their corresponding positioning posts 20, so that the movement of the inner core is more stable.

[0069] In order to facilitate the reset of the inner core, in a preferred embodiment, an elastic reset member 9 is sleeved on one end of the bottle body 5, and the two ends of the elastic reset member 9 are respectively in contact with the outer tube 1 and the bottle body 5. When the bottle body 5 is pressed, the elastic reset member 9 is compressed and stores force, and after the hand is released, the elastic reset member 9 pushes the bottle body 5 to move in the opposite direction to reset the inner core.

[0070] Or, if Fig.12 As shown, in a preferred embodiment, both ends of the elastic reset member 9 are respectively in contact with the pump head 4 and the bottle body 5. Specifically, the elastic reset member 9 is a spring, and the spring is sleeved on the pump head 4. When the bottle body 5 is pressed, more areas of the pump head 4 extend into the bottle body 5, thereby squeezing the spring. The spring is compressed and stores force. After the bottle body 5 is released, the spring pushes the end of the pump head 4 to move in the opposite direction, so that more areas of the pump head 4 extend out of the bottle body 5, thereby pushing the bottle body 5 to move in the opposite direction, so that the inner core is reset.

[0071] In addition, by selecting a suitable elastic reset member 9, in the initial state of the elastic reset member 9, a part of the inner core extends out of the outer shell. When installing the inner core and the outer shell, a certain pressure needs to be applied to the inner core so that the positioning column 20 enters the positioning hole, so that the positioning column 20 is limited by the positioning hole. At this time, the elastic reset member 9 completes the pre-compression process, which compresses the elastic reset member 9 to a certain extent, and can be further compressed on this basis to achieve the subsequent reset operation after pressing the inner core to squeeze the pump head 4. When disassembling the inner core, after rotating the connecting ring 2, when the positioning column 20 moves to the vicinity of the inclined surface, due to the elastic force of the elastic reset member 9, the elastic reset member 9 pushes the inner core so that the positioning column 20 moves upward along the inclined surface to the second groove body, and part of the structure of the inner core extends out of the outer shell, which is convenient for pulling out the inner core.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
