Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, specifically to a packaging bottle for a sunscreen stick. Background Technology

[0002] While moderate sunlight exposure is beneficial, prolonged outdoor activities can lead to sunburn and damage from ultraviolet (UV) rays. Without proper sun protection, skin is highly susceptible to sun damage. Sunscreen products, as commonly used cosmetics, use sunblock agents to block or absorb UV rays, preventing sunburn and tanning. Currently, most sunscreens, whether in cream, pump dispenser, or spray form, require application by hand, resulting in UV-protective agents remaining on the palms and needing to be washed off.

[0003] To address the aforementioned issues, Chinese utility model patent CN202121720982.3 (publication number CN215707979U) discloses a packaging bottle for a sunscreen stick, comprising: a bottle body, a connecting post, and an adjusting knob. The upper part of the bottle body has a receiving cavity for holding the sunscreen stick, and the top of the bottle body has an outlet communicating with the receiving cavity. The lower part of the bottle body has a channel communicating with the receiving cavity, and an opening communicating with the channel. The connecting post is retractably disposed within the channel, and its upper end is used to connect the sunscreen stick. The adjusting knob is disposed at the opening and exposed therefrom. The adjusting knob drives the connecting post to move up and down within the channel by rotation.

[0004] This patent offers a more convenient alternative to traditional sunscreens that require opening the bottle and applying it by hand. However, the bottle is a single piece, making it inconvenient to insert the adjustment knob inside. Furthermore, the patent does not disclose how the adjustment knob is vertically fixed relative to the bottle, nor can it be seen from the drawings. If the knob shifts vertically, it will affect the extension and retraction of the connecting column, which in turn will affect the up-and-down movement of the sunscreen stick, ultimately impacting user experience. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a packaging bottle for a sunscreen stick that is easy to assemble into the bottle body and position vertically, in view of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a packaging bottle for a sunscreen stick, comprising...

[0007] The bottle body is vertically continuous, and a partition is horizontally arranged inside the bottle body. The partition divides the bottle body into an upper space and a lower space. The partition is provided with a through hole connecting the upper space and the lower space. The side wall of the bottle body is provided with an opening corresponding to and communicating with the lower space.

[0008] A knob, with its rotation axis extending vertically, is located in the lower space and partially within an opening;

[0009] The drive lever is coaxial with the knob and the two are fixedly connected.

[0010] A lifting rod is inserted into a drive rod and the two are threaded together, with the upper end of the lifting rod extending into the upper space;

[0011] The lifting frame, which is fixedly connected to the upper end of the lifting rod, is used to hold sunscreen sticks;

[0012] The feature is that the knob and the drive rod can enter the lower space of the bottle body from the bottom opening from bottom to top, and the periphery of the through hole is formed with a downwardly extending ring body, which is sleeved on the drive rod. The two are fixed relative to each other in the vertical direction but can rotate relative to each other in the circumferential direction.

[0013] The bottom of the bottle is provided with a base, which covers the bottom opening of the bottle when the knob and drive rod are in the lower space.

[0014] The annular body limits the upper part of the drive rod, so the base has a vertically extending limiting tube. When the annular body and the drive rod are assembled, the lower end of the drive rod is limited within the limiting tube, and in this state, the knob is partially located in the opening. This limiting tube thus limits the lower part of the drive rod to prevent it from wobbling during rotation and affecting the transmission of the lifting rod.

[0015] Preferably, the annular body is detachably connected to the drive rod, and the base is detachably connected to the bottle body. This allows for easy repair or replacement of the knob and drive rod when needed. The base can be removed, and the annular body can be detached from the drive rod. Since the drive rod and lifting rod are threaded together, they are also detachable, enabling repair or replacement of the knob and drive rod without discarding the entire packaging bottle, thus saving energy and protecting the environment.

[0016] To achieve detachable connection between the annular body and the drive rod, various methods can be used, such as magnetic attraction. However, this method is not convenient for achieving relative displacement between the two in the circumferential direction. Therefore, preferably, the annular body has a retaining foot on its inner circumferential wall, and the drive rod has a retaining groove along its circumference on its outer circumferential wall. The retaining foot is engaged in the retaining groove and can slide along the groove. Alternatively, the annular body has a retaining groove along its circumferential direction on its inner circumferential wall, and the drive rod has a retaining foot on its outer circumferential wall. The retaining foot is engaged in the retaining groove, and the two can generate relative displacement in the circumferential direction. The engagement method of the retaining foot and retaining groove is simple in structure and ensures that the annular body and the drive rod are vertically fixed without affecting their relative displacement in the circumferential direction.

[0017] To achieve a detachable connection between the base and the bottle, and with a simple structure, the outer peripheral wall of the base and the inner peripheral wall of the bottle are detachably connected together via protrusions and slots.

[0018] To improve the connection between the base and the bottle, a limiting plate is provided on the base. When the base and the bottle are connected, the two opposite sides of the limiting plate abut against the two walls of the bottle. The abutment between the limiting plate and the bottle increases the connection between the base and the bottle, but under the action of external force, the base can detach from the bottle.

[0019] In the above design, a stepped surface is formed on the outer peripheral wall of the bottle. The packaging bottle also includes a cap, which is detachably mounted on the top of the bottle, with its bottom resting on the stepped surface. The cap serves to protect the sunscreen stick from contamination and also enhances its appearance.

[0020] To further protect the sunscreen stick from contamination, a sealing cap is detachably provided at the top opening of the bottle, and the sealing cap can be covered by the bottle cap.

[0021] To improve the stability of the sunscreen stick placed on the lifting frame, the lifting frame includes a base plate and a limiting cylinder extending upward from the periphery of the base plate to limit the position of the sunscreen stick, and the lifting rod is fixedly connected to the base plate.

[0022] Compared with the prior art, the advantages of this utility model are: the bottom of the bottle body of this utility model is open, which makes it easy for the knob and drive rod to enter the lower space from bottom to top, so that the knob is partially located in the opening, and it is also easy to connect the ring body and the drive rod to achieve vertical positioning of the knob and drive rod; after the knob and drive rod are assembled, the base is then assembled on the bottle body to prevent foreign objects from entering the lower space and damaging the internal components.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1-8 As shown, the packaging bottle of the sunscreen stick in this preferred embodiment includes a bottle body 1, a knob 2, a drive rod 3, a lifting rod 4, a lifting frame 5, a ring-shaped body 6, a base 7, a bottle cap 8, and a sealing cap 9.

[0033] like Figure 3 , 4 As shown, the bottle body 1 is vertically continuous, and a partition 11 is horizontally arranged inside the bottle body 1. The partition 11 divides the inside of the bottle body 1 into an upper space 12 and a lower space 13. The partition 11 is provided with a through hole 111 connecting the upper space 12 and the lower space 13.

[0034] The side wall of the bottle body 1 has an opening 14 that communicates with the lower space 13. The rotation axis of the knob 2 extends vertically. The knob 2 is located in the lower space 13 and partially in the opening 14 to facilitate the user's operation of the knob 2. The drive rod 3 and the knob 2 are coaxial and fixedly connected. When the knob 2 rotates, it drives the drive rod 3 to rotate synchronously. In this embodiment, the drive rod 3 and the knob 2 are designed separately. The drive rod 3 passes through the knob 2 and the two are tightly fitted. Alternatively, they can be integrally formed.

[0035] The lifting rod 4 is inserted into the drive rod 3 and the two are threaded together. When the knob 2 drives the drive rod 3 to rotate, the lifting rod 4 moves up and down. The upper end of the lifting rod 4 extends into the upper space 12 and is fixedly connected to the lifting frame 5. The lifting frame 5 is used to hold the sunscreen stick and can move up and down synchronously with the lifting rod 4. In this embodiment, the lifting frame 5 includes a base plate 51 and a limiting cylinder 52 extending upward from the periphery of the base plate 51. The limiting cylinder 52 limits the sunscreen stick, and the lifting rod 4 is fixedly connected to the base plate 51.

[0036] During assembly, the lifting rod 4 and the lifting frame 5 are inserted from top to bottom through the top opening of the bottle body 1. The lifting frame 5 is located in the upper space 12, and the lifting rod 4 passes through the through hole 111 and is partially located in the lower space 13.

[0037] The knob 2 and the drive rod 3 can enter the lower space 13 of the bottle body 1 from the bottom opening of the bottle body 1 from bottom to top. The periphery of the through hole 111 is formed with a downwardly extending ring 6. The ring 6 is sleeved on the drive rod 3. The two are fixed relative to each other in the vertical direction but can rotate relative to each other in the circumferential direction. The bottom of the bottle body 1 is provided with a base 7. When the knob 2 and the drive rod 3 are in the lower space 13, the base 7 covers the bottom opening of the bottle body 1.

[0038] After the knob 2 and drive rod 3 are assembled, the base 7 is then assembled onto the bottle body 1 to prevent debris from entering the lower space 13 and damaging the internal components.

[0039] In addition, in this embodiment, the annular body 6 is detachably connected to the drive rod 3, and the base 7 is detachably connected to the bottle body 1. This allows for easy repair or replacement of the knob 2 and drive rod 3 when they need maintenance or replacement. The base 7 can be removed, and the annular body 6 can be detached from the drive rod 3. Since the drive rod 3 and the lifting rod 4 are threadedly connected, they are also detachable. This allows for maintenance or replacement of the knob 2 and drive rod 3 without discarding the entire packaging bottle, thus saving energy and protecting the environment.

[0040] The inner circumferential wall of the annular body 6 is provided with a latch 61, and the outer circumferential wall of the drive rod 3 is provided with a latch groove 31 along its circumference. The latch 61 is fastened in the latch groove 31 and can slide along the latch groove 31, so as to realize the detachable connection between the annular body 6 and the drive rod 3. The matching method of the latch 61 and the latch groove 31 is simple in structure, and while ensuring that the annular body 6 and the drive rod 3 are vertically fixed, it will not affect their relative displacement in the circumferential direction.

[0041] Alternatively, the inner circumferential wall of the annular body 6 may be provided with a groove 31 along its circumference, and the outer circumferential wall of the drive rod 3 may be provided with a foot 61. The foot 61 is fastened in the groove 31 and the two can generate relative displacement in the circumferential direction.

[0042] To enable the detachable connection between the base 7 and the bottle 1, the outer peripheral wall of the base 7 and the inner peripheral wall of the bottle 1 are detachably connected together via a protrusion 15 and a slot 71. In this embodiment, the protrusion 15 is provided on the base 7 and the slot 71 is provided on the bottle 1. Alternatively, the protrusion 15 can be provided on the bottle 1 and the slot 71 can be provided on the base 7.

[0043] The base 7 is also provided with a limiting plate 72. When the base 7 is connected to the bottle body 1, the two opposite sides of the limiting plate 72 abut against the two walls of the bottle body 1 respectively. The abutment between the limiting plate 72 and the bottle body 1 increases the connection between the base 7 and the bottle body 1. However, under the action of external force, the base 7 can also be detached from the bottle body 1.

[0044] As can be seen from the above, the annular body 6 limits the upper part of the drive rod 3. Therefore, in this embodiment, a vertically extending limiting tube 73 is also formed on the base 7. When the annular body 6 and the drive rod 3 are assembled in place, the lower end of the drive rod 3 is limited in the limiting tube 73, and in this state, the knob 2 is partially located in the opening 14. In this way, the limiting tube 73 limits the lower part of the drive rod 3 to prevent the drive rod 3 from shaking during rotation, affecting the transmission of the lifting rod 4, and ensuring that the knob 2 is always partially located in the opening 14 for easy operation by the user. Anti-slip strips can be provided on the outer peripheral wall of the knob 2.

[0045] A stepped surface 16 is formed on the outer peripheral wall of the bottle body 1. The packaging bottle also includes a bottle cap 8, which is detachably mounted on the top of the bottle body 1, with its bottom resting on the stepped surface 16. The bottle cap 8 serves to protect the sunscreen stick from contamination and for aesthetic purposes. The bottle cap 8 can be made of metal. The bottle cap 8 and the bottle body 1 are connected by a detachably connected insert 17 and a groove. The insert 17 is detachably embedded in the groove and can be dislodged from the groove under external force. In this embodiment, the insert 17 is located on the bottle body, and the groove is located on the bottle cap.

[0046] To further protect the sunscreen stick from contamination, a removable sealing cap 9 is provided at the top opening of the bottle 1, which can be covered by the bottle cap 8. When the sunscreen stick needs to be used, first remove the sealing cap 9, then remove the bottle cap 8, and then turn the knob 2 to extend the sunscreen stick upwards from the bottle 1 for use.
