Description

Technical Field

[0001] The utility model belongs to the technical field of caps for packaging bottles, and more specifically, particularly relates to a cap for a lotion packaging bottle with a suction function. Background Art

[0002] In daily life, personal care products such as lotions are widely used in skin care, providing users with various functions such as cleaning and nourishing. As key components of lotion products, packaging bottles and their caps affect the user experience. During use, when the user presses the cap, excessive lotion often flows out.

[0003] For example, the Chinese utility model patent with the patent number 202322032435.1 provides a cap for a lotion packaging bottle with a suction function. Through the settings of a pump head, a lotion pump, a liquid outlet, a suction channel, a return pipe, and a suction pump, when in use, by pressing the pump head, the lotion flows out from the liquid outlet through the lotion pump. When the pump head rebounds after being pressed, the suction pump discharges the air in the packaging bottle to form a negative pressure, enabling the suction channel and the return pipe to recycle the excess lotion. However, the traditional cap needs to first press the pump head to discharge the lotion, and can only be recycled during the rebound of the pump head. When not enough is recycled at one time, it is necessary to press the pump head again to pump out the lotion and then recycle it again, with relatively complex operations, resulting in a lack of convenience. Summary of the Utility Model

[0028] The following further describes in detail the embodiments of the present utility model with reference to the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0029] Example:

[0030] As shown in Figure 1 to Figure 9 the figure:

[0031] The utility model provides a bottle cap for emulsion packaging with a back suction function, which includes a cap body 11. A first installation groove 12 and a second installation groove 13 are opened at the top of the cap body 11. The first installation groove 12 is used for installing a liquid pumping component, and the second installation groove 13 is used for installing a recovery component. This separated design enables the two functions of liquid pumping and recovery to be operated independently, allowing users to flexibly choose whether to perform liquid pumping or recovery operations according to actual needs, without the need for complex steps such as first pumping out the emulsion and then recovering it like traditional bottle caps, greatly improving the convenience of use. The recovery component includes a negative pressure pump 21 and a telescopic recovery hose 22. The negative pressure pump 21 is installed on the second installation hole 14 at the bottom of the second installation groove 13, and the pumped emulsion can be sucked back into the bottle through suction. A slidable recovery pressing block 23 is arranged at the opening of the second installation groove 13. A recovery channel 24 is opened on the recovery pressing block 23. One end of the recovery hose 22 is connected to the negative pressure pump 21, and the other end passes through the recovery channel 24. Users only need to press the recovery pressing block 23 to drive the negative pressure pump 21 to suck the overflowed emulsion back into the bottle through the recovery hose 22, avoiding waste. It not only improves the recovery efficiency but also can adjust the length of the recovery hose 22 according to actual needs to minimize the risk of emulsion overflow. The recovery channel 24 on the pressing block can not only provide a channel for the recovery hose 22 but also ensure its sealing performance, further improving the recovery effect.

[0032] Please refer to as Figure 3 , Figure 4 and Figure 5 shown, a recovery pipe 25 communicating with the recovery channel 24 is arranged at the bottom of the recovery pressing block 23. A connection kit 26 is further arranged at the bottom of the recovery pipe 25, and the bottom of this connection kit 26 is connected to the liquid inlet end of the negative pressure pump 21, combining the user's operation behavior with the suction force of the negative pressure pump 21, enabling the overflowed emulsion to be quickly and efficiently sucked back into the bottle, improving the convenience of use.

[0033] Please refer to as Figure 4 and Figure 5 shown, the recovery component further includes a second return spring 27. A second return spring 27 is sleeved on the top of the negative pressure pump 21, and the top of this second return spring 27 is connected to the connection kit 26. In this way, after the user presses the recovery pressing block 23 to complete the recovery operation, the second return spring 27 can automatically reset the pressing block 23, providing convenience for the next use. At the same time, a strengthening structure 28 is arranged on one side of the recovery pressing block 23 corresponding to the recovery channel 24, and one end of the recovery hose 22 passes through this strengthening structure 28 and is connected with a recovery end 29, which can not only ensure the sealing performance of the recovery hose 22 but also effectively guide the backflow of the emulsion, thus further improving the recovery effect.

[0034] Please refer to asFigure 6 , Figure 7 and Figure 8 As shown, the pump assembly includes a liquid outlet pump 31. A first mounting hole 15 is provided at the bottom of the first mounting groove 12. The liquid outlet pump 31 is installed at the bottom of the first mounting hole 15. The liquid inlet end of the liquid outlet pump 31 is also connected to a liquid inlet hose 32 for extracting the emulsion from the container into the liquid outlet pump 31.

[0035] Please refer to Figure 7 and Figure 8 As shown, in addition, a pump liquid pressing block 33 is also arranged in the first installation groove 12, and the bottom of the pump liquid pressing block 33 is connected to a connecting tube 34, and the bottom of the connecting tube 34 is provided with a connecting head 35, and the bottom of the connecting head 35 is directly connected to the liquid outlet pump 31, which plays a role of receiving and transmitting. At the same time, one end of the first return spring 36 is in contact with the connecting head 35, and the other end is sleeved on the outside of the liquid outlet pump 31, which not only ensures the smooth connection between the liquid outlet pump 31 and the upper component, but also can automatically reset the pump liquid pressing block 33 through the action of the first return spring 36 after the user operation is completed, providing convenience for the next use.

[0036] Please refer to Figure 7 and Figure 8 As shown, a liquid outlet channel 37 communicating with the connecting tube 34 is also provided on the pump liquid pressing block 33, and a liquid outlet nozzle 38 is provided at the end of the liquid outlet channel 37 away from the connecting tube 34, one end of the liquid outlet nozzle 38 is connected to a liquid outlet hose 39, and the other end of the liquid outlet hose 39 is connected to the liquid outlet end of the liquid outlet pump 31; in this way, when the liquid outlet pump 31 is working, the emulsion can be transported to the liquid outlet nozzle 38 through the liquid outlet hose 39, and finally sprayed out; it is worth mentioning that the liquid outlet hose 39 is penetrated inside the liquid outlet channel 37 and the connecting tube 34, which can not only ensure the smoothness of liquid transportation, but also effectively avoid the occurrence of problems such as squeezing or kinking of the hose, further improving the reliability of the product.

[0037] Please refer to Figure 9 As shown, a threaded opening 16 which can be connected to the packaging bottle is provided at the bottom of the bottle cap body 11, so that the entire bottle cap can be firmly installed on the packaging bottle. In order to facilitate the user to twist the bottle cap, an anti-slip structure 17 is also provided on the surrounding side of the bottle cap body 11, which not only increases the feel when twisting, but also improves the overall convenience of operation.
