[0032] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiment is only one embodiment of the present invention, not all embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that, unless otherwise defined, the technical or scientific terms used in this application should have the common meanings understood by persons having ordinary skills in the field to which the invention belongs.

[0034] In the description of the embodiments of the present invention, “a plurality of” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] To address the aforementioned issues with existing technologies, related art has proposed a packaging container with a dual-chamber structure. The bottle has a mouth at one end and an opening at the other end. The opening houses an inner chamber and a pressing portion for connecting the inner chamber to the bottle's receiving chamber. The openings at both ends of the bottle reduce its strength and can easily cause damage. Furthermore, the presence of the pressing portion, which protrudes from the opening, makes it very easy to misuse the container, resulting in undesirable mixing of the material in the inner chamber with the material in the bottle's receiving chamber.

[0036] The present invention addresses the technical issues of accessories being easily lost and misoperation caused by the provision of an additional pressing portion. By providing a new packaging container, the present invention employs a method different from that used in prior art and related technologies to connect the inner cavity and the bottle's receiving cavity. The packaging container of the present invention can be used to package cosmetics. When used to package cosmetics, the packaging container of the present invention can be referred to as a cosmetic packaging container.

[0037] See also Figures 1 to 6 The packaging container of the embodiment of the present invention includes: an outer bottle body 20, an inner bottle body 50, a conducting member 70, a limiting ring 40 and a bottle cap 10.

[0038] The outer bottle body 20 defines an outer accommodating cavity 201 for accommodating a first material. The outer bottle body 20 includes an outer bottle body 21 and a bottle mouth portion 23 connected to the outer bottle body 21. The outer bottle body 20 may have an opening only at the bottle mouth portion 23, with the remaining portions being a closed structure, thereby improving both the structural strength of the outer bottle body 20 and the aesthetics of the outer bottle body 20. The diameter of the bottle mouth portion 23 is smaller than the diameter of the outer bottle body 21. The outer bottle body 21 may be connected to the bottle mouth portion 23 via a shoulder portion 22. The bottle cap 10 is connected to the bottle mouth portion 23 for opening or closing the bottle mouth portion 23.

[0039] The inner bottle body 50 is disposed within the outer accommodating chamber 201. The inner bottle body 50 defines an inner accommodating chamber, isolated from the outer accommodating chamber 201, for accommodating the second material. The first material and the second material can be liquids of different compositions. A conductive member 70 is removably disposed within the outer accommodating chamber 201, connecting the inner accommodating chamber and the outer accommodating chamber 201 to allow mixing of the second material with the first material.

[0040] The limiting ring 40 is detachably sleeved on the radial outer side of the bottle mouth portion 23. It is easy to understand that when the limiting ring 40 is sleeved on the radial outer side of the bottle mouth portion 23, the limiting ring 40 is located between the shoulder 22 and the bottle cap 10.

[0041] When the limiting ring 40 is sleeved on the radially outer side of the bottle mouth 23, the bottle cap 10 can move along the bottle mouth 23 toward the outer bottle body 21 to the first position where it abuts against the limiting ring 40 (see Figure 1 and Figure 2 ); When the limiting ring 40 is removed from the bottle mouth portion 23, the bottle cap 10 can move from the first position along the bottle mouth portion 23 to a second position closer to the outer bottle body 21 (see Figure 4 When the bottle cap 10 moves from the first position to the second position, the bottle cap 10 can drive the conducting member 70 to move in the outer accommodating cavity 201 in a direction away from the bottle mouth 23 , thereby connecting the inner accommodating cavity and the outer accommodating cavity 201 .

[0042] The embodiment of the present application provides an inner bottle body 50 and an outer bottle body 20, so that the first material and the second material can be stored separately; by providing a limit ring 40 and a conductive member 70, when the packaging container is not in use, due to the presence of the limit ring 40, the bottle cap 10 remains in the first position and cannot move to the second position, so that the conductive member 70 cannot connect the inner accommodating chamber and the outer accommodating chamber 201, so that the first material and the second material can be stored separately; when used for the first time, the limit ring 40 is removed first and then the bottle cap 10 is locked. During the locking process, the conductive member 70 is squeezed by the bottle cap 10 and moves in the outer accommodating chamber 201 in the direction away from the bottle mouth 23, thereby connecting the inner accommodating chamber and the outer accommodating chamber 201.

[0043] The limiting ring 40 in the embodiment of the present application is sleeved on the radial outside of the bottle mouth 23, so it is not easy to be lost when the package is not opened; and when using it for the first time, it is only necessary to remove the limiting ring 40 from the bottle mouth 23 and re-lock the bottle cap 10, which is simple to operate and greatly reduces the possibility of misoperation.

[0044] See also Figure 7 The outer side of the bottle mouth 23 of the outer bottle body 20 is formed with a thread. Figure 8 The bottle cap 10 is provided with a thread groove 121 for threaded connection with the bottle mouth 23. The bottle cap 10 includes an inner cap 12 and an outer cap 11. The inner cap 12 is threadedly connected with the bottle mouth 23 to close the liquid outlet channel 311 of the outer bottle plug 30. The outer cap 11 is sleeved on the inner cap 12. In some embodiments, see Figure 9 and Figure 10 The limiting ring 40 has a central through hole 401 , and the bottle cap 10 can be removed first, and then the limiting ring 40 can be removed from the bottle mouth 23 .

[0045] The end surface of the limiting ring 40 facing the bottle cap 10 includes a flat surface 41 located on the outside and an inclined surface 42 connected to the flat surface 41 and protruding toward the bottle cap 10. Correspondingly, the end surface of the bottle cap 10 facing the outer bottle body 21 forms a flat surface located on the outside and an inclined surface 122 connected to the flat surface 41, so that the limiting ring 40 can be locked by using the bottle cap 10.

[0046] In some embodiments, the inner bottle body 50 may be in the form of a capsule structure as a whole. When the conductive member 70 moves toward the capsule structure, it pierces the capsule structure, thereby releasing the second material inside the capsule structure into the outer accommodating cavity 201 .

[0047] In some embodiments, the inner bottle body 50 is provided with a first opening 513. In some embodiments, a sealing membrane is disposed at the first opening 513. When the bottle cap 10 moves from the first position to the second position, the bottle cap 10 drives the conductive member 70 toward the sealing membrane, thereby piercing the sealing membrane and establishing communication between the inner and outer receiving chambers 201, thereby enabling the first and second materials to be mixed. The first opening 513 can be positioned facing the bottle mouth 23 to facilitate piercing the sealing membrane by the conductive member 70. In other embodiments, the first opening 513 can be positioned away from the bottle mouth 23, allowing the conductive member 70 to enter the inner bottle body 50 and pierce the sealing membrane.

[0048] In some embodiments, a sealing film may not be provided at the first opening 513, and the packaging container further includes an inner stopper 60 for sealing the first opening 513 of the inner bottle body 50. During the movement of the bottle cap 10 from the first position to the second position, the conductive member 70 can drive the inner stopper 60 to move away from the bottle mouth 23 to open the first opening 513 (i.e., the inner stopper 60 no longer seals the first opening 513). After the inner stopper 60 opens the first opening 513, the inner accommodating chamber and the outer accommodating chamber 201 are connected, thereby allowing the first material and the second material to be mixed together. The first opening 513 can be provided facing the bottle mouth 23 so that the conductive member 70 can drive the inner stopper 60 to move. In other embodiments, the first opening 513 can also be provided facing away from the bottle mouth 23, and the conductive member 70 enters the inner bottle body 50 to drive the inner stopper 60 to move.

[0049] In some embodiments, see Figure 13 The inner bottle stopper 60 may include: a stopper body 61 and a plurality of stoppers 631. The stopper body 61 is used to close the first opening 513 of the inner bottle body 50. The plurality of stoppers 631 are connected to the stopper body 61. When the stopper body 61 moves in a direction away from the bottle mouth portion 23 to open the first opening 513, the plurality of stoppers 631 stop at the first opening 513. That is, when the bottle cap 10 moves to the second position, the conductive member 70 drives the inner bottle stopper 60 to slide to a suspended state, thereby connecting the inner accommodating chamber and the outer accommodating chamber 201. Since the inner bottle stopper 60 is in a suspended state, it will not fall into the outer accommodating chamber 201 and affect the appearance.

[0050] In some embodiments, the inner stopper 60 may further include a head portion 63 and a connecting portion 62. The connecting portion 62 is used to connect the head portion 63 to the stopper body 61. The diameter of the connecting portion 62 is smaller than that of the head portion 63, which in turn is smaller than the diameter of the first opening 513. A plurality of stoppers 631 extend radially outward from the head portion 63. This arrangement ensures that when the stopper body 61 is disengaged from the first opening 513, a gap remains between the first opening 513 and the connecting portion 62 of the inner stopper 60, thereby allowing the first material and the second material to mix.

[0051] In some embodiments, there may be two stoppers 631 , which are disposed opposite to each other on the circumferential surface of the head 63 .

[0052] In some embodiments, a first opening 513 is provided at one end of the inner bottle body 50 away from the bottle mouth 23. Figure 14 The conductive member 70 may include a sealing portion 71 and a rod portion 72. Figure 6 The sealing portion 71 is disposed in the inner receiving chamber, and the sealing portion 71 divides the inner receiving chamber into a first space 501 and a second space, wherein the first space 501 is used to accommodate the second material, and the first opening 513 is connected to the first space 501. The rod portion 72 extends from the sealing portion 71 to the inner bottle stopper 60 in the inner receiving chamber.

[0053] In the illustrated embodiment, the first space 501 is located below the second space, the first opening 513 is located at the bottom of the inner bottle body 50, and the sealing portion 71 is located above the stem portion 72. The sealing portion 71 and the inner stopper 60 together seal the first space 501, thereby storing the second material in a relatively sealed environment, which is beneficial for the preservation of the second material.

[0054] Continue to see Figure 6 The sealing portion 71 may include an end portion 711 and an annular side portion 712 extending downward from a radially outer peripheral edge of the end portion 711. The end portion 711 is connected to the rod portion 72. A plurality of protrusions may be formed on the surface of the annular side portion 712 to enhance the sealing between the annular side portion 712 and the outer bottle body 20.

[0055] See also Figure 12 The inner wall of the inner bottle body 50 forms an abutment surface 502; when the bottle cap 10 moves to the second position, the periphery of the sealing portion 71 abuts against the abutment surface 502. The abutment surface 502 supports the conductive member 70 and keeps it in the inner bottle body 50, preventing the conductive member 70 from moving further toward the inner bottle stopper 60 without support, thereby squeezing and deforming the stopper 631 of the inner bottle stopper 60 and causing the inner bottle stopper 60 to separate from the inner bottle body 50.

[0056] See also Figure 11 and Figure 12The inner bottle body 50 includes an inner bottle body 51. The inner bottle body 51 has a first opening 513 at one end away from the bottle mouth 23 and a second opening 512 at the other end facing the bottle mouth 23. The second opening 512 faces the bottle mouth 23. The conductive member 70 enters the inner housing chamber of the inner bottle body 50 through the second opening 512.

[0057] The packaging container may further include an outer stopper 30 having a liquid outlet passage 311, movably disposed radially inwardly of the bottle mouth 23. The bottle cap 10 is used to seal the liquid outlet passage 311. The inner cap 12 may be formed with a sealing post 123 adapted to fit within the liquid outlet passage 311. The sealing post 123 is embedded in the liquid outlet passage 311 to seal the liquid outlet passage 311.

[0058] During the movement of the bottle cap 10 from the first position to the second position, the bottle cap 10 can drive the outer bottle stopper 30 to move in the bottle mouth portion 23 toward the first opening 513, and then drive the conductive member 70 to move in the inner receiving cavity through the outer bottle stopper 30.

[0059] The inner bottle body 50 further includes a hanging portion 52 formed around the second opening 512 of the inner bottle body 51. The inner bottle body 51 is disposed within the outer accommodating cavity 201. The hanging portion 52 extends radially outward from the second opening 512 beyond the bottle mouth 23 to suspend the inner bottle body 51 from the bottle mouth 23. In this embodiment, the outer bottle stopper 30 is disposed within the second opening 512 of the inner bottle body 51.

[0060] The hanging portion 52 can be a flange extending outward from the second opening 512 of the inner bottle body 51, which engages with the bottle mouth 23. Specifically, the hanging portion 52 includes an annular portion 521 and an annular side portion 522. The annular side portion 522 extends downward from the radially outer periphery of the annular portion 521. The end of the annular side portion 522 can form a hook. Accordingly, a groove is formed radially outward of the bottle mouth 23, and the annular side portion 522 engages with the groove of the bottle mouth 23 via the hook.

[0061] The sidewall of the inner bottle body 51 is formed with an inner bottle lateral through-hole 511, through which the second space of the inner accommodating chamber communicates with the outer accommodating chamber 201. In this embodiment, material within the outer accommodating chamber 201 can enter the second space of the inner accommodating chamber through the inner bottle lateral through-hole 511, and then enter the liquid outlet channel 311 of the outer bottle stopper 30 through the second space.

[0062] See also Figure 15 and Figure 16The outer bottle stopper 30 may include: a sealing ring 32 and a tube portion 31. The sealing ring 32 is provided at the second opening 512 of the inner bottle body 51 and is sealedly connected to the inner bottle body 51. A liquid outlet channel 311 is formed inside the tube portion 31, and the tube portion 31 extends axially from the radial inner side of the sealing ring 32. The tube portion 31 is formed with a tube portion lateral through hole 312, and the second space of the inner bottle body 51 is connected to the liquid outlet channel 311 of the bottle stopper through the tube portion lateral through hole 312. Thus, the material entering the second space of the inner accommodating chamber through the inner bottle lateral through hole 511 can enter the liquid outlet channel 311 through the tube portion lateral through hole 312.

[0063] The sealing ring 32 may include an annular end portion 321 and an annular side portion 322. The annular side portion 322 extends downward from the radially outer periphery of the annular end portion 321. The surface of the annular side portion 322 may be formed with a plurality of protrusions to enhance the sealing performance with the inner bottle body 51.

[0064] In the initial position, the limiting ring 40 is sleeved on the radial outer side of the bottle mouth 23, the bottle cap 10 is in the first position, and the annular end 321 of the outer bottle plug 30 protrudes from the annular portion 521 of the inner bottle body 50 toward the bottle cap 10 (see Figure 3 When the limiting ring 40 is removed from the bottle mouth 23, the bottle cap 10 can continue to move along the bottle mouth 23 toward the outer bottle body 21, thereby driving the outer bottle plug 30 to move away from the bottle cap 10. When the bottle cap 10 moves to the second position, the annular end 321 of the outer bottle plug 30 is substantially flush with the annular portion 521 of the inner bottle body 50 (see Figure 6 ), thereby increasing the aesthetics of the packaging container when in use.

[0065] Regarding the embodiments of the present invention, it should also be noted that, in the absence of conflict, the embodiments of the present invention and the features therein may be combined with each other to obtain new embodiments.

[0066] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. The protection scope of the present invention shall be based on the protection scope of the claims.
