[0042] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] See also Figures 1 to 8 A spring-free cosmetic packaging container is shown, comprising:

[0044] An outer bottle 1 having a mounting cavity;

[0045] A container bottle 2, which is fixedly disposed in the mounting cavity and has a receiving cavity for receiving cosmetics;

[0046] A pump core assembly 3 is mounted at the mouth of the container bottle 2. The pump core assembly 3 includes at least a connecting rod 30 extending in the vertical direction. The connecting rod 30 defines a liquid outlet channel 31 extending in the vertical direction. The liquid outlet channel 31 communicates with the accommodating chamber of the container bottle 2. When the connecting rod 30 moves downward relative to the container bottle 2, the cosmetics in the accommodating chamber can be pumped out through the liquid outlet channel 31.

[0047] A button 4 is fixedly mounted on the top of the connecting rod 30 and is provided with a liquid outlet 41. The liquid outlet 41 is connected to the liquid outlet channel 31 so that the pumped cosmetics can be sprayed out of the liquid outlet 41 through the liquid outlet channel 31 for use by the user.

[0048] The shoulder sleeve 5 is fixedly mounted on the top of the outer bottle 1. The button 4 is slidably mounted on the shoulder sleeve 5 in the vertical direction. An installation space Z is formed between the top of the outer bottle 1, the shoulder sleeve 5, and the button 4. The upper portion of the connecting rod 30 is located within the installation space Z and is fixedly connected to the button 4. An opening 51 is formed on the outer periphery of the shoulder sleeve 5, and the opening 51 is in communication with the installation space Z.

[0049] The bracket 6 can be rotatably arranged on the top of the outer bottle 1 around a rotation center line extending in the horizontal direction. The bracket 6 has a clamping rod 61 and a pressing piece 62 respectively arranged on different sides of the rotation center line. The clamping rod 61 has at least a clamping sleeve portion 61a that is fitted on the outer periphery of the connecting rod 30, wherein the pressing piece 62 can be fitted through the opening 51.

[0050] The packaging container has a first use state and a second use state. When the packaging container is in the first use state, the button 4 is not pressed, the pressing piece 62 is cooperatively arranged in the opening 51, and the outer side surface of the pressing piece 62 is flush with the outer side surface of the shoulder sleeve 5; and when the packaging container is switched to the second use state, the button 4 is pressed downward, and the clamping rod 61 of the bracket 6 moves downward with the connecting rod 30, so that the bracket 6 rotates around the rotation center line, and the pressing piece 62 rotates outward and cooperatively passes through the opening 51, and at least part of the pressing piece 62 is exposed outside the opening 51. When the packaging container is switched from the first use state to the second use state, when the button 4 is pressed downward, as shown in FIG. Figure 6 As shown, the connecting rod 30 can be moved downward to pump the cosmetics in the container bottle 2 outward. At this time, the bracket 6 rotates so that the pressing piece 62 extends out of the opening 51. Then, the pressing piece 62 is pushed toward the shoulder sleeve 5, or the button 4 is pulled upward, as shown. Figure 7 As shown, the bracket 6 can be rotated around the center line of rotation, so that the clamping portion 61a of the clamping rod 61 swings upward, and then the connecting rod 30 and the button 4 move upward and reset. After the connecting rod 30 and the button 4 are completely reset, the packaging container is reset to the first usage state.

[0051] See also Figures 1 to 8 As shown, the pressing piece 62 of the bracket 6 extends in the up-down direction. When the packaging container is in the second use state, that is, after the button 4 is pressed downward, the lower end of the pressing piece 62 extends outside the opening 51, and the outer side surface of the pressing piece 62 extends outward from top to bottom. The packaging container also includes an outer cover 7 that can be fitted on the outer periphery of the shoulder sleeve 5. In the process of the outer cover 7 being fitted onto the shoulder sleeve 5 and covering the upper part of the shoulder sleeve 5, the outer cover 7 can act downward on the outer side surface of the pressing piece 62, thereby driving the pressing piece 62 to rotate inward toward the shoulder sleeve 5, thereby automatically converting the packaging container from the second use state to the first use state. In this way, it is very simple to use the packaging container. That is, when it is necessary to pump out the cosmetics, open the outer cover 7 and then press the button 4 downward; when it is not needed, directly cover the outer cover 7 onto the shoulder sleeve 5.

[0052] The packaging container can be a single-cavity or multi-cavity type. Accordingly, the outer bottle 1 has one or more mounting cavities, each of which is provided with a container bottle 2, and each of which is provided with a group of pump core assemblies 3. The clamping rod 61 of the bracket 6 is provided with multiple clamping sleeves 61a, and the number of the clamping sleeves 61a is consistent with the number of the container bottles 2. All the clamping sleeves 61a are respectively and correspondingly clamped on the connecting rods 30 of the multiple pump core assemblies 3. When the button 4 is pressed, all the connecting rods 30 can be driven downward at the same time to simultaneously pump out the cosmetics in all the container bottles 2.

[0053] This embodiment provides a dual-chamber cosmetic packaging container, that is, the outer bottle 1 has two mounting cavities, and correspondingly, the container bottle 2 and the pump core assembly 3 are each provided with two. The bracket 6 has two clamping parts 61a, and the two clamping parts 61a are respectively clamped on the connecting rods 30 of the two pump core assemblies 3, so that the cosmetics in the two container bottles 2 can be pumped out simultaneously when the button 4 is pressed.

[0054] See also Figures 1 to 24 As shown, the structures of the various components in the packaging container of this embodiment are detailed as follows:

[0055] The outer bottle 1 has two mounting cavities for the two container bottles 2 to be removably mounted therein. The upper portion of the container bottle 2 has a cylindrical mounting cylinder 21. The upper portion of the outer bottle 1 is provided with two mounting holes 11 into which the two mounting cylinders 21 can be inserted. The mounting cylinders 21 can be inserted into the mounting holes 11 in a mating manner, and a screw-on structure is provided between the outer periphery of the mounting cylinder 21 and the inner periphery of the mounting hole 11 to rotate with each other to securely mount the mounting cylinder 21. Here, the screw-on structure includes a plurality of positioning grooves 12 provided on the inner periphery of the mounting hole 11, and a plurality of positioning protrusions 22 provided on the outer periphery of the mounting cylinder 21. During the process of inserting the mounting cylinder 21 into the mounting hole 11, the container bottle 2 is rotated, so that the positioning protrusions 22 slide along the positioning grooves 12 and finally engage with the positioning points on the positioning grooves 12, thereby achieving the fixed installation of the container bottle 2 on the outer bottle 1.

[0056] Each container bottle 2 is provided with a bottom cover 9 for rotating the container bottle 2. Specifically, the bottom of the container bottle 2 is an open structure, and the bottom cover 9 is also used to close the bottom of the container bottle 2. During assembly, the piston 8 is first placed in the designated position in the container bottle 2, and then the bottom cover 9 is sealed on the open bottom of the container bottle 2. Figure 13 、 Figure 14 As shown, the bottom cover 9 includes a plug body 91 that fits snugly into the container bottle 2, and a mounting ring 92 located below the plug body 91. The outer diameter of the mounting ring 92 is larger than that of the plug body 91. One or more radially outwardly extending positioning protrusions 93 are provided on the outer periphery of the mounting ring 92 for mating with the mounting slots 24 at the bottom of the container bottle 2. A radially extending rib 94 is also fixedly disposed within the mounting ring 92. Both sides of the rib 94 form an operating space for a user's fingers to penetrate. This allows a user to rotate the container bottle 2 by gripping the rib 94, thereby enabling screwing and removal of the container bottle 2 from the outer bottle 1.

[0057] The bottom of the outer bottle 1 is also detachably provided with a limiting bottom plate 10 for limiting the two container bottles 2 in the vertical direction, see Figure 15As shown, the limiting base plate 10 is provided with two through holes 101, through which the ribs 94 at the bottom of the two groups of container bottles 2 can be exposed for rotation operation. The outer periphery of the limiting base plate 10 is also provided with positioning protrusions 102 protruding radially outward, which are used to cooperate with the positioning grooves (not shown in the figure) at the bottom of the outer bottle 1 to achieve fixed installation.

[0058] The shoulder sleeve 5 is installed on the top of the outer bottle 1 and is installed in correspondence with the two container bottles 2. Figure 18 As shown, the shoulder sleeve 5 is provided with two assembly rings 52. The two assembly rings 52 can be correspondingly inserted into the mouths of the two container bottles 2 to form a sealed connection between the container bottles 2. The main bodies of the two sets of pump core assemblies 3 are inserted into the assembly rings 52 and installed in conjunction with the shoulder sleeve 5, thereby achieving a fixed installation on the mouths of the container bottles 2. The outer periphery of the shoulder sleeve 5 has an upwardly protruding annular flange 54, and the opening 51 is formed in the annular flange 54. The upper portion of the connecting rod 30 of the pump core assembly 3 is located within the inner space of the annular flange 54 and is connected to the bracket 6 within this inner space.

[0059] See also Figure 9 、 Figure 10 As shown, the top of the outer bottle 1 has an upwardly projecting, annular mounting flange 16. The outer peripheral wall of this mounting flange 16 is provided with a plurality of outwardly projecting ribs 15. The shoulder sleeve 5 is fitted over the outer peripheral portion of the mounting flange 16 and secured to the top of the outer bottle 1 via these ribs 15. A connecting post is also formed on one sidewall of the mounting flange 16. This connecting post constitutes the rotating shaft 13 for the bracket 6 to be rotatably connected relative to the outer bottle 1. A latching hole 14 is formed below the rotating shaft 13.

[0060] See also Figure 19 、 Figure 20 As shown, the outer end of the clamping rod 61 of the bracket 6 has a clamping column 64 extending downward, and the lower end of the clamping column 64 has a protrusion 65 protruding and extending toward the pressing piece 62. When the bracket 6 is installed on the outer bottle 1, the rotating shaft 13 is axially passed through between the clamping column 64 and the pressing piece 62, and the protrusion 65 is correspondingly clamped in the clamping hole 14, which enables the bracket 6 to be stably installed on the top of the outer bottle 1 and can rotate relative to the outer bottle 1 around the axis of the rotating shaft 13.

[0061] Here, the clamping rod 61 of the bracket 6 includes a connecting rod portion 62b and two clamping sleeve portions 61a provided on both sides of one end of the connecting rod portion 62b. The two clamping sleeve portions 61a are both open U-shaped, and the opening of the clamping sleeve portion 61a is away from the connecting rod portion 62b. Figure 17As shown, the upper portion of the connecting rod 30 of the pump core assembly 3 has a cylindrical connecting rod portion 32 and an annular limiting flange 33 located at the top of the connecting rod portion 32. The clamping portion 61a is clamped on the outer periphery of the connecting rod portion 32 through its U-shaped opening, allowing the clamping portion 61a to both rotate relative to the connecting rod 30 and slide relative to the length of the connecting rod 30, thereby cooperating with the up and down movement of the connecting rod 30 and the rotation of the bracket 6 about the rotation axis 13. The outer diameter of the limiting flange 33 is larger than the outer diameter of the connecting rod portion 32 to axially limit the clamping portion 61a.

[0062] The connecting rod portion 62b extends in an arcuate shape. The bottom of the connecting rod portion 62b is also provided with a plurality of reinforcing ribs 66 extending along its length to increase the strength of the clamping rod 62. The other end of the connecting rod portion 62b is connected to the pressing plate 62. A stepped stop surface 63 is formed at the junction of the clamping rod 61 and the pressing plate 62. When the button 4 is not pressed, that is, when the packaging container is in the first use state, the stop surface 63 abuts upward against the upper side wall of the opening 51, thereby completely sealing the opening 51 with the pressing plate 62.

[0063] See also Figures 1 to 8 As shown, the button 4 is slidably inserted into the inner space formed by the annular flange 54 and slidably connected to the inner peripheral wall of the annular flange 54, and the button 4 is fixedly mounted on the top of the two connecting rods 30. Specifically, see Figures 21 to 23 As shown, the bottom of the button 4 has two hollow mounting posts 42, each designed to be mounted correspondingly with the two sets of connecting rods 30. In this embodiment, the bottom of the button 4 is also provided with two liquid outlet pipes 43. The two liquid outlet pipes 43 extend outward from the mounting posts 42 toward the liquid outlet 41. Here, the two liquid outlet pipes 43 extend in a V-shape. The lumens of the two liquid outlet pipes 43 connect the inner lumens of the mounting posts 42 and the liquid outlet 41. The inner lumens of the mounting posts 42 and the lumens of the liquid outlet pipes 43 cooperate to form a liquid spray channel on the button 4 that connects the liquid outlet channel 31 on the connecting rod 30 with the liquid outlet 41 on the button 4. Of course, in other embodiments, the two liquid outlet pipes 43 can extend in parallel or in other configurations and converge at the liquid outlet 41. The cosmetics in the two container bottles 2 can enter the two liquid spray channels of the button 4 through their respective liquid outlet channels 31. Then, they merge through the liquid outlet 41 and are sprayed out together for mixing and simultaneous use by the user.

[0064] A plurality of ribs 53 are further provided on the outer periphery of the shoulder sleeve 5 for elastically engaging with the outer cover 7 for detachable installation.

[0065] During use of the dual-chamber cosmetic packaging container of this embodiment, the user simply opens the outer cover 7 and presses the button 4 downward, causing the connecting rods 30 of the two pump core assemblies 3 to move downward simultaneously, thereby simultaneously pumping the cosmetics from the two container bottles 2 outward. The cosmetics from the two container bottles 2 flow through the respective liquid outlet channels 31 of the two connecting rods 30, then through the two spray channels on the button 4, and converge at the liquid outlet 41, where they are simultaneously pumped outward for use by the user. While the button 4 is being pressed, the sleeve portion 61a of the bracket 6 is driven downward, causing the bracket 6 to rotate about the rotation axis 13, causing the pressing piece 62 to extend outward from the opening 51. In the absence of external force, the bracket 6 remains in the state in which the pressing piece 62 extends outward and cannot automatically reset.

[0066] When the next pressing operation is required, the user can push the pressing plate 62 inward toward the shoulder sleeve 5 so that the pressing plate 62 returns to the opening 51. During this process, the bracket 6 rotates around the rotation axis 13, the clamping sleeve portion 61a moves upward and drives the connecting rod 30 to move upward and reset.

[0067] If the cosmetics do not need to be pumped out any more after being pumped out once, the user can also put the outer cover 7 on the shoulder sleeve 5. In the above process, the pressing piece 62 is also pushed toward the shoulder sleeve 5, thereby resetting the bracket 6 and the connecting rod 30.

[0068] In summary, the spring-free cosmetic packaging container of this embodiment no longer uses elastic parts, but uses a bracket 6 to allow the connecting rod 30 to reset upward after pumping out the cosmetics. The bracket 6 can be obtained by mold molding using recyclable plastic materials, so that the entire cosmetic packaging container can be recycled, avoiding environmental pollution and waste of resources. At the same time, the bracket 6 can be directly set in the space between the shoulder sleeve 5 and the button 4, occupying a small space, and can be used in various types of push-type packaging containers, and is also relatively easy to install.
