[0041] The existing liquid makeup (such as lip gloss, lip balm), skin care and other liquid cosmetics are prone to stratification when standing, and some cosmetics have multiple different components, which are prone to deterioration after mixing for a long time.

[0042] To solve the above problems, see Figures 1-7 An embodiment of the present application provides a packaging tube for mixing multiple liquid cosmetics, comprising a tube body 100, an application element 200, a pushing element 300, a driving element 400 and a guide element 500.

[0043] The tube body 100 has multiple independent chambers 130 arranged along the axial direction for storing liquid cosmetics, and each chamber is used to store different liquid cosmetics. The specific number can be adaptively selected according to actual needs.

[0044] The application element 200 is fixedly installed at one end of the tube body 100 and has a mixing chamber 210 inside. The top has a liquid outlet hole 220 communicating with the mixing chamber 210. The application element 200 is provided with passages connecting each chamber to the mixing chamber 210. Preferably, each chamber has a passage connected to the mixing chamber 210.

[0045] The pushing element 300 is movably installed in the tube body 100 and comprises multiple pistons 310 and a transmission rod 330 connected to the multiple pistons 310. The transmission rod 330 is provided with a protrusion 331, and the multiple pistons are respectively arranged in the corresponding chambers. The driving element 400 is a cylindrical structure, and the inner wall is provided with a spiral groove 410 matched with the protrusion 331 of the transmission rod 330, which is used to drive the pushing element 300 to move along the axial direction, so that the pistons in each chamber move synchronously.

[0046] The guide element 500 is rotationally matched with the driving element 400 and fixedly connected with the tube body 100, and has a limiting hole 510 through which the transmission rod 330 passes to limit the rotation of the transmission rod 330 along the circumference of the driving element 400. Specifically, the guide element 500 is sleeved on the outer periphery of the driving element 400, and the top is provided with a limiting hole 510, and the transmission rod 330 passes through the limiting hole 510 and matches with the spiral groove 410. The fixing mode of the guide element 500 and the tube body 100 can be as shown in Figure 1 and Figure 5 The outer periphery of the guide element 500 is provided with a convex ring 501 and a positioning rib 502, and correspondingly, the bottom of the tube body 100 is provided with an annular groove 101 and a positioning groove 102. The convex ring 501 and the annular groove 101 are matched to realize axial limiting, and the positioning rib 502 and the positioning groove 102 are matched to realize circumferential limiting. Of course, in order to improve the operation feeling, a plurality of elastic pieces 420 can be arranged on the outer peripheral wall of the driving element 400 in the circumferential direction. When rotating, the elastic pieces 420 rub against the inner peripheral wall of the guide element 500 to generate a torsion.

[0047] The present application sets multiple chambers for storing liquid cosmetics in the pipe body, and sets corresponding pistons in the chambers. When the cosmetics are needed, the guide element is rotated relative to the driving element, the driving pushing element is axially moved, the pistons in the chambers are synchronously moved upward, the liquid cosmetics in the chambers are synchronously flowed into the mixing chamber through the channels, mixed and then squeezed out from the liquid outlet. Since the volume of the mixing chamber is small, the mixed liquid can be quickly used up, avoiding the phenomenon that the cosmetics are deteriorated after long time mixing in the prior art, and the liquid cosmetics which cannot be stored for a long time can be stored for a long time.

[0048] For convenience of illustration, the following embodiments are described by taking two chambers as an example, and the principles are the same in other cases.

[0049] As shown in Figures 1-6 , the chambers 130 include a first chamber 131 and a second chamber 132, and the pistons 310 include a first piston 311 arranged in the first chamber 131 and a second piston 312 arranged in the second chamber 132. The channels include a first channel 231 connecting the first chamber 131 and the mixing chamber 210 and a second channel 232 connecting the second chamber 132 and the mixing chamber 210.

In addition, the anti-disengagement structure is further provided between the positioning column 111 and the positioning hole 250, so that the two can be quickly and correctly assembled.

[0053] In the embodiment, the anti-disengagement structure comprises two positioning blocks 112 provided on the positioning column 111 and two clamping grooves 251 located at the bottom surface of the positioning hole 250 and matched with the two positioning blocks 112 one by one, wherein the axial heights of the two positioning blocks 112 are different, and during assembly, the two positioning blocks 112 can be inserted and matched according to the heights.

[0054] Further, the anti-disengagement structure comprises the ring groove 252 located on the peripheral wall of the positioning hole 250 and the protrusion 113 provided on the positioning column 111 and matched with the ring groove 252. In order to further prevent disengagement, the bottom of the application element 200 is further provided with the clamping hook 270 matched with the edge of the opening 103 of the sealing plate 110, and the number of the clamping hook 270 is two and symmetrically arranged.

This design can determine whether the assembly is in place, and further, the outer surface of the limiting portion 260 is flush with the outer surface of the pipe body 100, which makes the whole more beautiful.

[0056] In order to ensure the air tightness, referring to Figure 7 The piston of the present application comprises the plate-shaped portion 313 and the cylindrical portion 314 extending along the axis of the plate-shaped portion 313, and the top end of the cylindrical portion 314 has the flange 315 which is in interference fit with the inner wall of the pipe body 100.

[0057] In order to further strengthen the air tightness, the outer peripheral wall of each piston is provided with the recess 320, and the sealing ring 321 is installed in the recess 320, and the sealing ring 321 is also in interference fit with the inner wall of the pipe body 100. The present application has two air tightness structures, which makes the air tightness better.

[0058] Specifically, during assembly, the two sealing rings 321 are matched with the recess 320 of the piston, then the guide element 500 is matched with the driving element 400, and then the two parts are assembled, and then the pipe body 100 and the guide element 500 are buckled and assembled in place. After the liquid cosmetic is filled, the application element 200 is pressed into the pipe body 100, and the assembly is completed.

[0059] Any technical features in the above-described embodiments can be combined in any manner, and for the sake of brevity, the foregoing descriptions of various embodiments do not describe all possible combinations. However, it should be understood that any combination of these technical features, unless specifically excluded, is within the scope of the present disclosure.
