The second connecting card slot is provided with a vertically provided raised card rib 213. Figure 3As shown;
[0022] The snap-fitting ridge 101 is arranged on the outer wall of the inner bottle assembly 1, and the horizontal length of the snap-fitting ridge 101 is less than or equal to the horizontal width of the first connecting groove 211, and the vertical height of the snap-fitting ridge 101 is less than or equal to the vertical height of the second connecting groove 212, so that the snap-fitting ridge 101 can enter the first connecting groove from the top starting end of the first connecting groove and then move in the second connecting groove and the second connecting groove; the middle part of the snap-fitting ridge 101 is provided with a vertically arranged positioning groove 102, when the snap-fitting ridge 101 enters the second connecting groove 212 and is snapped into place, the raised clip rib 213 can be snapped into the positioning groove 102, see Figure 2 shown.
[0023] In this embodiment, the inner bottle assembly 1 includes an inner bottle 11 with an opening at the top, and a lotion pump sealed and fixedly connected to the opening at the top of the inner bottle. The lotion pump includes a pump body 14, a piston seat 15, a piston rod 16, a connecting seat 17, a connecting rod 18, an elastic return member 13 and a connecting sleeve 10, wherein the piston seat 15 and the piston rod 16 are arranged inside the pump body 14, and the connecting seat 17 is sealed and installed at the upper end of the pump body 14; the lower end of the connecting rod 18 extends into the pump body 14 and cooperates with the piston seat 15 and the piston rod 16, and the upper end of the connecting rod 18 extends upward from the pump body 14, the elastic return member 13 is provided on the upper part of the pump body 14 and is sleeved on the outside of the connecting rod 18, the lower end of the elastic return member 13 abuts against the connecting seat 17, and the upper end of the elastic return member 13 abuts against the connecting rod 18, and the elastic return member 13 is a plastic elastic tube, see Figure 6 As shown, the connecting sleeve 10 is mounted outside the pump body and is fixedly connected to the piston seat 15. The top open outer wall of the inner bottle 13 is fixedly connected to the connecting sleeve 10. The engaging protrusions 101 and the positioning grooves 102 are provided on the outer wall of the connecting sleeve 10. The operating principle of the lotion pump can be found in the Chinese utility model patent publication number CN 219651758 U and will not be described in detail here.
[0024] The inner bottle assembly 1 further comprises a pressing cap 12 connected to the top of the lotion pump. An annular guide sleeve 121 is formed inside the pressing cap 12. The inner wall of the annular guide sleeve 121 is provided with a vertically arranged guide positioning rib 122. Figure 4 As shown; the connecting sleeve 10 is formed with an upwardly disposed annular positioning sleeve 105, an annular guide sleeve 121 is sleeved outside the annular positioning sleeve 105, the outer wall of the annular positioning sleeve 105 is provided with a guide positioning groove 103 that cooperates with the guide positioning rib 122, see Figure 5As shown. The outer wall of the annular positioning sleeve 105 is further formed with a transversely or obliquely arranged locking groove 104. The side of the locking groove 104 is connected to the guide positioning groove 103, and the upper end of the locking groove 104 extends to the upper opening of the annular positioning sleeve 102. The pressing cap 12 can rotate relative to the connecting sleeve 10. When the guide positioning rib 122 is located in the guide positioning groove 103, the pressing cap 12 can move up and down relative to the connecting sleeve 10, thereby exerting a force on the connecting rod 18 of the lotion pump. When the pressing cap 12 is rotated so that the lower end of the guide positioning rib 122 moves into the locking groove 104, the pressing cap 12 is locked and cannot move up and down relative to the connecting sleeve 10. The interior of the pressing cap 12 is formed with a pressing column 123 located at the center of the annular guide sleeve 121. The lower end of the pressing column 123 abuts against the upper end of the connecting rod 18 of the lotion pump. An annular clamping sleeve 106 arranged downward is formed inside the connecting sleeve 10 , and the outer side of the upper opening of the inner bottle 11 is clamped to the annular clamping sleeve 106 through a buckle.
[0025] The entire vacuum lotion bottle is gasket-free. Users rotate and replace the inner bottle by engaging the inner bottle assembly's snap-fitting ridges 101 and positioning grooves 102 with the outer bottle assembly's L-shaped slots 21 and raised retaining ribs 213. The user presses the cap 12 to close the bottle, preventing it from being pushed up or down. Turning it right opens the bottle, allowing it to be pressed up and down to dispense liquid. The entire lotion pump features an all-plastic pump core with no metal springs, ensuring environmental protection. The inner bottle and lotion pump utilize a snap-on connection for enhanced safety and contamination resistance, preventing consumers from easily opening the bottle and contamination.
