AI Technical Summary
Existing cosmetic refill bottles have fixed capacities, which cannot adapt to changes in the amount of cosmetics during different times of the trip. This forces users to prepare refill bottles of various sizes, which is inconvenient.
An adjustable-capacity cosmetic dispensing bottle was designed. The capacity is changed by adjusting the sleeve and threaded connection. The capacity is adjusted by unfolding or folding the flexible connecting ring. The bottle includes a threaded connection of an upper connecting ring, a flexible connecting ring and a lower connecting ring, combined with the design of a sliding groove and a sliding boss.
It enables flexible adjustment of the capacity of cosmetic dispensing bottles, meeting the needs of different scenarios and improving user convenience.

Description
Technical Field
[0001] This utility model relates to the field of cosmetic bottles, and in particular to an adjustable-capacity cosmetic dispensing bottle. Background Technology
[0002] When traveling for business or leisure, women need to carry some cosmetics with them to meet their makeup needs during the trip. Since cosmetic packaging is often quite large, carrying it all increases the weight of luggage. As a result, various types of travel-sized bottles have appeared on the market. The capacity of travel-sized bottles is fixed, but the amount of cosmetics needed at different times of the trip is also different. Users need to prepare multiple sizes of travel-sized bottles to adapt to different usage needs, which is very inconvenient in actual use. Utility Model Content
[0003] To address the aforementioned problems, this utility model proposes an adjustable-capacity cosmetic dispensing bottle.
[0004] The technical solution adopted by this utility model is: an adjustable-capacity cosmetic dispensing bottle, comprising...
[0005] The upper bottle body has a liquid outlet and a first connection port at its upper and lower ends, respectively. The outer surface of the bottom end of the upper bottle body is provided with external threads, and a liquid outlet head is connected to the liquid outlet.
[0006] The lower bottle body has a second connection port at its upper end;
[0007] The adjustable bottle body includes a fixedly connected upper connecting ring, a flexible connecting ring, and a lower connecting ring. The upper connecting ring is threadedly connected to the first connecting port, and the lower connecting ring is threadedly connected to the second connecting port.
[0008] An adjusting sleeve is fitted onto the upper bottle body. The upper opening of the adjusting sleeve has an internal thread, which is threadedly connected to the external thread. The lower opening of the adjusting sleeve is rotatably connected to the lower connecting ring.
[0009] Furthermore, the lower connecting ring is provided with a sliding groove, and the lower opening of the adjusting sleeve is provided with a sliding boss, which is slidably connected to the sliding groove.
[0010] Furthermore, the surface of the flexible connecting ring is wavy, and the two ends of the flexible connecting ring are respectively bonded to the inner surfaces of the upper connecting ring and the lower connecting ring.
[0011] Compared with the prior art, this utility model has the following beneficial effects:
[0012] In this invention, the adjusting sleeve is threadedly connected to the upper bottle body. Users can rotate the adjusting sleeve to make the lower connecting ring rise or fall. During the adjustment process, the flexible connecting ring can be unfolded or folded, thereby changing the internal capacity of the dispensing bottle to meet the user's needs in different scenarios and provide convenience for the user's daily use.

[0019] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model proposes an adjustable-capacity cosmetic dispensing bottle, see reference. Figure 1 , 2The upper bottle body 1 is provided with a liquid outlet 11 and a first connection port 12 at its upper and lower ends, respectively. The outer surface of the bottom end of the upper bottle body 1 is provided with an external thread 13, and a liquid outlet head is connected to the liquid outlet 11. The lower bottle body 2 is provided with a second connection port 21 at its upper end.
[0022] See Figure 2 The adjustable bottle body 3 includes, from top to bottom, a fixedly connected upper connecting ring 31, a flexible connecting ring 32, and a lower connecting ring 33. The upper connecting ring 31 is threadedly connected to the first connecting port 12, and the lower connecting ring 33 is threadedly connected to the second connecting port 21.
[0023] See Figure 1 , 2 Adjusting sleeve 4 is fitted onto the upper bottle body 1. The upper opening of the adjusting sleeve 4 is provided with an internal thread 41, which is threadedly connected to the external thread 13. The height of the internal thread 41 is greater than that of the external thread 13. The lower opening of the adjusting sleeve 4 is rotatably connected to the lower connecting ring 33. The adjusting sleeve 4 and the lower connecting ring 33 maintain axial movement synchronization.
[0024] When using this product, the user rotates the adjusting sleeve 4. Driven by the internal and external threads 13, the adjusting sleeve 4 moves downward. The adjusting sleeve 4 drives the lower connecting ring 33 to move downward, gradually unfolding the flexible connecting ring 32, thereby increasing the internal capacity of the dispensing bottle. Similarly, when the adjusting sleeve 4 is rotated upward, the flexible connecting ring 32 gradually folds, which can reduce the internal capacity of the dispensing bottle. The capacity of the dispensing bottle can be changed according to the user's needs, thus providing convenience for the user's daily use.
[0025] See Figure 2 The lower connecting ring 33 is provided with a sliding groove 331, and the lower opening of the adjusting sleeve 4 is provided with a sliding boss 42. The sliding boss 42 is slidably connected in the sliding groove 331, and both the sliding groove 331 and the sliding boss 42 are annular.
[0026] See Figure 2 , 3 The surface of the flexible connecting ring 32 is wavy. The two ends of the flexible connecting ring 32 are respectively bonded to the inner surfaces of the upper connecting ring 31 and the lower connecting ring 33. There is a gap between the flexible connecting ring 32 and the adjusting sleeve 4, which allows the flexible connecting ring 32 in a folded state to be stored.
[0027] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
