[0003] A type of double-bin discharging package material currently on the market generally uses a press pump, and the material is squeezed out of two bottles and then discharged through the press cap outlet. When the outlet and the pump cores of the two bottles are in a straight line, the pump core near the press cap outlet will squeeze out the material first and discharge it through the outlet first, and the pump core far from the press cap outlet will squeeze out the material late and discharge it through the outlet late. This double-bin lotion pump structure has inconsistent discharge amounts of the two materials when first used and when the material is used up.

[0004] Another type of double-bin discharging package material has an outlet that is 90° relative to the pump cores of the two bottles, and the two pump cores can squeeze out the material at the same time, but the discharge is uneven, and the consumer needs to rub the two materials together in the palm after pumping out the material for use, which is inconvenient. Moreover, when the two materials are combined in the press cap, the material with good flowability will be pumped out first, and the material with poor flowability will be pumped out late, causing inconvenience in use.

[0005] In addition, all double-bin lotion pump package materials on the market do not have a replacement structure design, and when the lotion is used up, the entire package material is discarded, which not only wastes materials but also is not environmentally friendly. SUMMARY

[0020] Referring to Figures 1-6 , the dual-compartment dispensing package of the present application comprises an outer cover 1, a cap outer cover 2, a cap inner cover 3, an outer container 4, a shoulder cover 5, two pump cores 6, two inner bottles 7, and a base 8. The two inner bottles 7 contain liquid, and the two pump cores 6 are respectively inserted into the two inner bottles 7.

[0021] The cap inner cover 3 is provided with a liquid outlet groove 31 and a mixing channel 32. The front side of the liquid outlet groove 31 is provided with a liquid outlet hole 33, which is in communication with the outside through the mixing channel. The liquid outlet groove 31 is further provided with a partition rib 34, which divides the liquid outlet groove 31 into left and right liquid passages. The partition rib 34 also divides the liquid outlet hole 33 into left and right small holes, and the left and right liquid passages are respectively in communication with the left and right small holes. The left and right liquid passages are respectively in communication with the two inner bottles 7 through the two pump cores 6. When the cap outer cover 2 is pressed, the liquid in the two inner bottles is respectively pumped into the left and right liquid passages, mixed in the mixing channel 32, and then ejected from the cap inner cover 3. It is a known technology in the art to draw liquid from a liquid cavity through a cap and a pump core and pump it out, which is widely used in the fields of personal care products, spray pots, etc., and will not be described in detail.

[0022] By setting the internal position of the partition rib 34 relative to the liquid outlet hole 33, the proportion of the two liquids can be adjusted, so that the composition of the final mixed liquid can be adjusted according to different needs. For example, when the partition rib 34 is located at the middle position of the liquid outlet hole 33, the two liquids are ejected at a ratio of 1:1. In addition, in the prior art, the positions of the two pump cores for pumping out liquid and the position of the liquid outlet hole are almost in a straight line, so that the pump core close to the liquid outlet hole will pump out liquid first into the liquid outlet hole, thereby failing to achieve simultaneous liquid ejection. In the present application, since the outlets of the two pump cores are on both sides of the liquid outlet hole 33, simultaneous liquid ejection can be achieved.

[0023] The mixing channel 32 is provided with a mixing assembly 9, which comprises a first bearing 10, a second bearing 11, and a stirrer 12. The mixing channel 32 is externally provided with a nozzle 13.

[0024] The first bearing 10 is arranged at the inlet end of the mixing channel 32, and the second bearing 11 is arranged at the outlet end of the mixing channel 32. The stirrer 12 comprises a shaft 121 and blades 122 arranged in a spiral around the shaft 121. The two ends of the shaft 121 are supported by the first bearing 10 and the second bearing 11, respectively. When the two liquids pass through the mixing channel, the blades 122 are driven to rotate due to the obstruction of the blades 122, so that the stirrer 12 rotates around the shaft 121 in the mixing channel 32. Under the action of the stirrer 12, the two liquids are uniformly mixed and flow forward in the mixing channel 32, so that the mixed liquid is sprayed out of the nozzle 13 from the outlet end of the mixing channel.

[0025] The first bearing 10 comprises a cylinder wall 101 extending through the front and back, and a plurality of positioning ribs 102 arranged at intervals on the inner circumferential surface of the cylinder wall 101. The plurality of positioning ribs 102 extend from the inner circumferential surface of the cylinder wall to the inner center thereof, providing positioning and support for the shaft 121. Due to the structure of the positioning ribs, liquid can flow from one end of the first bearing 10 to the other end through the gaps between the positioning ribs 102.

[0026] At the end away from the shaft 121, the plurality of positioning ribs 102 are connected to each other at the end portion toward the center of the cylinder wall 101, thereby limiting the movement of the shaft 121 in the axial direction.

[0027] The second bearing 11 has substantially the same structure as the first bearing 10, and will not be described again.

[0028] The cap inner cover 3 further comprises a liquid outlet groove sealing cover 36 and a connecting plate 35. One end of the connecting plate 35 is hingedly connected to the cover of the cap inner cover 3, and the other end is connected to the liquid outlet groove sealing cover 36. By turning over the connecting plate 35, the liquid outlet groove sealing cover 36 is covered on the liquid outlet groove 31, thereby sealing the liquid outlet groove 31.

[0029] Further, the outer diameter of the first bearing 10 is smaller than the outer diameter of the second bearing 11. During the process of pumping out the liquid, on the one hand, the speed of the liquid is reduced due to the stirring and obstruction of the blades 122, and on the other hand, the flow rate of the liquid is reduced due to the expansion of the channel cross-sectional area during the outward flow of the liquid, because the outer diameter of the first bearing 10 is smaller than the outer diameter of the second bearing 11. The liquid is effectively prevented from being quickly pumped out and splashing everywhere.

[0030] In order to facilitate the replacement of liquid, the upper end outer wall of the shoulder cover 5 is provided with a first protrusion 51 and a second protrusion 52, the circumferential distance between the adjacent ends of the first protrusion 51 and the second protrusion 52 is d, the inner wall of the outer container 4 is provided with a positioning groove 41 and a limiting groove 42, the positioning groove 41 comprises a vertical groove 411 and a circumferential groove 412 communicated with the vertical groove 411, the distance between the end of the circumferential groove 412 away from the vertical groove 411 and the limiting groove 42 in the circumferential direction is also d, and the width of the vertical groove 411 is arranged to be capable of simultaneously accommodating the first protrusion 51 and the second protrusion 52 to move up and down therein.

[0031] When assembled, the shoulder cover 3 is inserted into the outer container 4, and the first protrusion 51 and the second protrusion 52 are aligned with the vertical groove 411, when inserted into the bottom end of the vertical groove 411, the shoulder cover 3 is rotated, the first protrusion 51 and the second protrusion 52 slide along the circumferential groove 412, when the first protrusion 51 abuts against the end face of the circumferential groove 412, it will be hindered, at this time, the torque is increased, under the elastic deformation of the first protrusion 51 or the outer container 4, the first protrusion 51 continues to move along the circumference by overcoming the positioning groove 41, the elastic force is released at the limiting groove 42, and is embedded in the positioning groove 42, at this time, the second protrusion is still in the circumferential groove 412, thereby preventing the two from being separated.

[0032] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
