[0002] Generally speaking, liquid or paste cosmetics (hereinafter referred to as "liquid contents") are usually stored in a cosmetic container equipped with a pump dispenser. The user dispenses a specific amount of liquid contents from the cosmetic container by repeatedly pressing the pump dispenser head of the cosmetic container.

[0003] However, there has recently been a trend toward hybrid cosmetics that offer multiple benefits in a single product. These products may combine a liquid base with additional ingredients, such as powders or special-effect liquids (e.g., vitamins or brighteners). To maintain the effectiveness of these functional cosmetics and prevent spoilage during distribution, consumers typically mix the base and additional ingredients before using the product. Consequently, there is a growing demand for dual cosmetic containers that can simultaneously mix and dispense multiple cosmetics.

[0004] This dual cosmetic container allows users to mix and use a variety of cosmetics with different raw materials, each with its own unique shelf life. This ensures an extended overall shelf life and maximizes the efficacy of the mixed cosmetics.

[0049] Figure 1 -8 shows a cosmetic container 1 for dispensing a fluid product, such as a liquid or any other fluid-like product, according to a preferred embodiment of the present disclosure. The product may be more viscous than water, or, optionally, even pasty. The cosmetic container 1 according to the present disclosure is used to uniformly mix two different types of liquid products during initial use, and then discharge the mixed contents in a single pumping operation. Figure 2 As shown, cosmetic container 1 is configured for mixing a first product P1 with a second product P2. The first and second products are liquid products. First product P1 is contained in first product container 30, and pump dispenser 20 is secured to neck 31 formed at the upper end of first product container 30. Second product P2 is contained in second product container 70.

[0050] Cosmetic container 1 includes a first product container 30, a second product container 70, a pump dispenser 20, an outer cap 10, a sealing cap 40, a piston 50, a lifter 60, and a dialer 80. The open lower end of first product container 30 is sealingly attached to second product container 70. Cosmetic container 1 allows the user to easily mix the first and second products within cosmetic container 1 by simply twisting dialer 80 before first use. Dialer 80 is designed to rotate around and enclose second product container 70. Simultaneously, lifter 60 is securely screwed into the lower portion of second product container 70, located below its reservoir chamber 72. Piston 50 is slidably positioned within reservoir chamber 72 below the second product P2. When dialer 80 rotates relative to first and second product containers 30, 70, it activates upward movement of lifter 60, which in turn applies pressure to piston 50 located within second product container 70. When the piston 50 rises toward the upper end of the second product container 70, the central rod 57 located on the upper side of the piston 50 pierces the rupturable area 43 of the sealing cap 40, which seals the upper portion of the second product container 70. As a result, the second product P2 contained in the second product container 70 is discharged into the first product container 30.

[0051] In this embodiment, the second product container 70 has a generally cylindrical shape along the main axis of the cosmetic container 1, and is tightly and hermetically mounted on the lower end of the first product container 30. The first product container 30 has a cylindrical sidewall 32 with a hollow interior to accommodate the first product P1, and a neck 31 with a neck external thread 31a is provided on the top thereof to mount the pump dispenser 20. In addition, the lower portion of the cylindrical sidewall 32 of the first product container 30 is open and has a portion 33 with an enlarged inner diameter, while forming a stepped jaw 34 so that the second product container 70 can be attached to the open lower interior. Figure 2 As shown, the inner surface of the lower portion of the cylindrical sidewall 32 of the first product container 30 includes a locking recess 35 that receives a corresponding second locking protrusion 78 b formed on the outer surface of the second product container 70 .

[0052] like Figure 4 and Figure 5As shown, second product container 70 includes at least one reservoir sidewall 71 defining a reservoir cavity 72 for storing a second product P2. Second product container 70 includes an open upper end 71a defined by the upper end of reservoir sidewall 71. Reservoir sidewall 71 includes a transversely extending annular wall 74 located at the lower end of reservoir cavity 72. Annular wall 74 defines a lower opening 79 of reservoir cavity 72. Furthermore, a cylindrical skirt 75 depends axially downward from an inner edge 74a of annular wall 74. Cylindrical skirt 75 also includes a locking point 75a located at or adjacent to the upper end of cylindrical skirt 75.

[0053] Second product container 70 includes an outer sidewall 73 positioned radially outwardly to dialer sidewall 81 of dialer 80. The upper end of outer sidewall 73 is connected to reservoir sidewall 71 by a transverse shoulder wall 76 located in the middle portion of reservoir sidewall 71. The lower end of outer sidewall 73 defines an open lower end 71b of second product container 70.

[0054] Reference Figure 2 The open upper end 71a of the second product container 70 is defined by the open upper end of the reservoir sidewall 71 and is adapted to be sealed by the sealing cap 40. The lower portion and the lower open end 71b of the outer sidewall 73 of the second product container 70 are engaged by the dialer 80. The dialer 80 is rotatably connected to the outer sidewall 73 of the second product container 70.

[0055] Reference Figure 2 , the second product P2 is accommodated in the reservoir chamber 72 on the upper side of the piston 50, and the open upper end 71a of the reservoir chamber 72 is closed by the sealing cover 40. Figure 6 and Figure 7 As shown, the sealing cover 40 includes a sealing cover top wall 41 and a sealing cover side wall 42 depending from the sealing cover top wall 41. The sealing cover top wall 41 includes a rupturable area 43, the thickness of which is less than the thickness of the remaining portion of the sealing cover top wall 41. The rupturable area 43 is an annular groove 44 formed on the upper surface of the sealing cover top wall 41. In addition, the sealing cover side wall 42 of the sealing cover 40 includes a sealing cover annular locking groove 45 formed on the inner surface thereof. The sealing cover annular locking groove 45 of the sealing cover 40 receives a corresponding first locking protrusion 78a formed on the outer surface of the reservoir side wall 71 of the second product container 70, for connecting the second product container 70 to the sealing cover 40.

[0056] The circumferential size of the upper portion of the outer sidewall 73 of the second product container 70 complements the circumferential size of the inner circumference of the lower portion of the first product container 30 so that the lower portion of the outer sidewall 73 of the second product container 70 is sealedly disposed inside the first product container 30 .

[0057] like Figure 2 As shown, the second product container 70 accommodates the lifter 60 so that the lifter 60 closes the lower opening 79 of the reservoir cavity 72. The lifter 60 is threadedly engaged to the cylindrical skirt 75 of the second product container 70 by engaging the locking point 75a of the second product container 70 with the side wall thread 67 formed on the outer surface of the lifter 60. The locking point 75a of the second product container 70 is protruding, while the side wall thread 67 of the lifter is a grooved thread.

[0058] Refer to Figure 8 and Figure 9 The lifter 60 includes a transverse top wall 65 and a lower cylindrical side wall 63 extending downward from the lower surface of the transverse top wall 65. A connecting skirt 64 extends upward from the upper surface of the transverse top wall 65 and is located in the center of the transverse top wall 65. The lower cylindrical side wall 63 also includes a closed side wall upper end 61 and an open side wall lower end 62 opposite to its side wall upper end 61. The transverse top wall 65, the side wall lower end 62 and the lower cylindrical side wall 63 of the lifter 60 define an internal cavity 66. A side wall thread 67 is formed on the outer surface of the lower cylindrical side wall 63 of the lifter 60. The transverse top wall 65 includes an annular flange 68, which extends radially outward as a radial extension of the transverse top wall 65.

[0059] Reference Figure 2 In the second product container 70, the annular flange 68 of the transverse top wall 65 of the lifter 60 abuts against the annular wall 74 of the second product container 70 and closes the opening of the reservoir cavity 72. In this state, the connecting skirt 64 of the lifter 60 protrudes into the reservoir cavity 72 of the second product container 70, and the lower cylindrical side wall 63 is threadedly engaged with the inner surface of the cylindrical skirt 75 via the corresponding side wall threads 67 and the locking point 75a.

[0060] The sidewall threads 67 of the lifter 60 are grooved threads with stop protrusions 67a and 67b at their ends. The stop protrusions 67a and 67b define the retraction and advancement ends of the lifter 60. When the locking point 75a of the second product container 70 abuts the stop protrusion 67a at the upper end of the sidewall threads 67 of the lifter 60, the lifter 60 is prevented from further descending. When the locking point 75a of the second product container 70 abuts the stop protrusion 67b at the lower end of the sidewall threads 67 of the lifter 60, the lifter 60 is prevented from further ascending.

[0061] Reference Figure 10 and Figure 11The dialer 80 includes a dialer sidewall 81 having an open dialer upper end 82 and a dialer lower end 83 enclosed by a bottom wall 84. The dialer 80 includes an inner post 86 coaxially arranged with and integrally formed with the dialer 80. The inner post 86 extends axially upward from the inner surface of the bottom wall 84. The dialer 80 is rotatably connected to the second product container 70 and moves the lifter 60 through its rotation. The outer diameter of the dialer sidewall 81 is formed to be the same as the outer diameter of the first product container 30. Therefore, a stepped portion is not formed on the outer surface of the cosmetic container 1, but can be formed smoothly.

[0062] A dialer annular locking groove 87 is formed on the inner surface of the dialer side wall 81 of the dialer 80. A third locking protrusion 78c is formed on the outer surface of the outer side wall 73 of the second product container 70. The dialer annular locking groove 87 of the dialer 80 receives the third locking protrusion 78c of the second product container 70. Therefore, the dialer 80 can be rotated relative to the second product container 70 without being separated from the second product container 70.

[0063] A receiving cavity 89 is formed between the dialer side wall 81 and the inner column 86 of the dialer 80. The receiving cavity 89 is configured to receive the lower portion of the second product container 70 (see FIG. Figure 2 When the lower portion of the second product container 70 is received in the dialer 80, the outer sidewall 73 and the cylindrical skirt 75 are received in the receiving cavity 89 of the dialer 80. The inner column 86 of the dialer 80, the lower cylindrical sidewall 63 of the lifter 60, and the cylindrical skirt 75 of the second product container 70 are coaxially sleeved in sequence from the inside to the outside.

[0064] Reference Figure 2 , piston 50 is movably received in reservoir chamber 72 of second product container 70. When the second product P2 in reservoir chamber 72 is to be discharged, piston 50 is axially movable toward the upper end of second product container 70, as will be explained in more detail later. Piston 50 is movable, for example, by being pushed upward by lifter 60. Lifter 60 is specifically designed so that piston 50 is positioned on top of lifter 60. When the second product P2 is to be discharged from second product container 70 to be mixed with the first product P1, piston 50 is moved from the lower end of reservoir chamber 72 toward the upper end of reservoir chamber 72 by means of lifter 60.

[0065] Reference Figure 12 and Figure 13 The piston 50 has a piston body 51 and a first piston lip 52 and a second piston lip 53 formed on the outer periphery of the piston body 51. The first piston lip 52 and the second piston lip 53 are configured to slide in contact with each other in a reservoir cavity 72 formed by the inner surface of the reservoir side wall 71 without leaking (see Figure 2 ). The piston 50 is advantageously made as a single part. The first piston lip 52 and the second piston lip 53 form a seal for the second product P2, by which the second product P2 is prevented from being discharged from the lower end of the reservoir chamber 72. In addition, the piston 50 comprises a connecting annular sleeve 55 which extends downwardly from the piston body 51 and is configured to be securely connected to the connecting skirt 64 of the lifter 60, see Figure 2 . Thus, when the lifter 60 moves axially upwardly therewith in the reservoir chamber 72, the piston 50 is also urged to move in an upward direction. In addition, the piston body 51 includes a central rod 57 coaxially positioned on and extending upwardly from the piston body 51. The central rod 57 of the piston 50 includes an inclined upper edge 56 that is configured to exert a force on the rupturable region 43, causing it to rupture and separate from the remainder of the sealing cap 40. As a result of this action, a hole 46 is formed in the sealing cap 40. This hole 46 serves as a conduit that enables the second product P2 to be discharged into the first product container 30 to be mixed with the first product P1.

[0066] The lifter 60 is coupled to the dialer 80 to convert the rotary motion of the dialer 80 into a linear reciprocating motion. Figure 2 、 Figure 8B and Figure 10 , the inner post 86 of the dialer 80 has a non-circular cross-section, and similarly, the lower cylindrical sidewall 63 of the lifter 60 has an inner periphery configured to match the non-circular cross-sectional shape of the inner post 86. In the illustrated embodiment, as Figure 10 As shown, the inner column 86 of the dialer 80 has a rectangular shape with two opposing flat sides 86a and two opposing curved sides 86b. The lower cylindrical sidewall 63 of the lifter 60 is mounted on the rectangular inner column 86 of the dialer 80 to prevent any relative rotational movement between the lifter 60 and the dialer 80 during operation. Therefore, when in use, the lifter 60 moves in unison in the axial direction relative to the dialer 80. Therefore, the lifter 60 can be lifted within the reservoir chamber 72 in conjunction with the rotation of the dialer 80. In other words, the lifter 60 is coupled to the dialer 80 to convert the rotational motion of the dialer 80 into linear reciprocating motion.

[0067] The pump dispenser 20 includes a support body 21 threadedly mounted on the neck 31 of a first product container 30. The support body 21 includes a coupling portion 22 having coupling threads 22a, which engage with external neck threads 31a formed on the outer surface of the neck 31 of the first product container 30. The support body 21 is configured to secure a pumping assembly disposed within the neck 31 of the first product container 30. The pumping assembly includes a cylinder 23 having a pressure chamber 23a formed therein to temporarily store product from the first product container 30. This product is drawn into the cylinder via a suction tube 24 secured to the lower end of the cylinder 23. The pumping assembly also includes a hollow piston rod 25, the lower end of which is located within the cylinder 23 and the upper end of which passes through the center of the support body 21. The hollow piston rod 25 is configured to move / slide vertically. Furthermore, a check valve 26 is provided, which opens and closes a cylinder inlet 27 formed at the bottom of the cylinder 23 in response to changes in pressure within the pressure chamber 23a. A dispensing head 28 is fixed to the upper end of the hollow piston rod 25 and has a discharge port 28a formed on one side. A coil spring 29 is disposed between the hollow piston rod 25 and the support body 21, elastically supporting the hollow piston rod 25 upwards together with the dispensing head 28. When the dispensing head 28 is pressed downward, the hollow piston rod 25 moves downward, compressing the coil spring 29. Consequently, the pressure in the pressure chamber 23a increases, and the product temporarily stored therein is transferred to the hollow piston rod 25 and discharged to the outside through the discharge port 28a of the dispensing head 28. When the external force pressing the dispensing head 28 is removed, the hollow piston rod 25 rises again under the elastic supporting force of the coil spring 29, and the check valve 26 opens. The product stored in the first product container 30 is again drawn through the suction tube 24. Various other types of dispensing mechanisms or other pump mechanisms known in the art may be used to dispense product from the first product container 30 within the scope and range of the present disclosure.

[0068] Next, we will refer to Figure 2 、 Figure 14 and Figure 15 The use and effects of the cosmetic container 1 according to the present disclosure constructed as described above are described.

[0069] Initially, before the first use of the cosmetic container 1 according to the present disclosure, as Figure 2As shown, a first product P1 is contained within a first product container 30, while a second product P2 is stored within a second product container 70. Thus, the first product P1 and the second product P2 remain separate. To initiate mixing of the two liquid products P1 and P2, the user rotates the dialer 80 relative to the first product container 30. This action causes both the inner column 86 and the lifter 60, driven by the dialer 80, to rotate synchronously. Assuming that the second product container 70 remains stationary relative to the first product container 30, the lifter 60 simultaneously moves upward along the locking point 75a of the second product container 70 during its rotational movement. As the lifter 60 rises, it exerts upward pressure on the piston 50, forcing it to move in an upward direction. As the piston 50 rises, the center rod 57 of the piston 50 applies pressure, causing the rupturable area 43 to rupture, thereby forming an opening (hole 46) in the sealing cap 40, see FIG. Figure 14 The hole 46 allows the second product P2 to flow into the first product container 30, promoting its mixing with the first product P1. The piston 50 eventually reaches its highest position, displacing the entire second product P2 from the reservoir chamber 72 into the first product container 30 and contacting the inner surface of the sealing cap 40, see Figure 15 .

[0070] Then, the user can shake the cosmetic container 1 to evenly mix the first product P1 and the second product P2. When the user removes the outer cover 10 and presses the dispensing head 28 of the pump dispenser 20, the first product P1 and the second product P2 mixed in the first product container 30 are discharged to the outside.

[0071] The present disclosure is not limited to the broadest disclosure based on the basic ideas disclosed herein. It should be interpreted as having a scope. Those skilled in the art can achieve patterns in non-real-time manners by combining or replacing the disclosed embodiment shapes, which does not depart from the scope of the present invention. In addition, those skilled in the art can easily change or modify the disclosed embodiments based on this specification, and it will be obvious that such changes or modifications also fall within the scope of the present disclosure.
