[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Herein, the terms "upper", "lower", "inner", "outer", etc., indicating directions or positional relationships, are defined for reference based on the direction observed by the user when using the cosmetic packaging container. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present application.

[0032] Figures 1 to 10 The drawings are drawn in true proportion. To keep the specification concise, the proportions of each component are not listed one by one. However, the proportions and positions of each component should be regarded as part of the content of this specification.

[0033] See also Figures 1 to 10 A cosmetic packaging container is shown, which includes a container body 20 and a container cover 10. The container body 20 includes a base 4 with an inner cavity and a connecting seat 5 arranged on the upper part of the base 4. The inner cavity of the base 4 is used to hold cosmetics. The connecting seat 5 is fixedly arranged on the upper part of the base 4. The connecting seat 5 is hollow and annular, and its inner cavity is connected with the inner cavity of the base 4. The container cover 10 can be cooperatively sleeved on the circumferential outer side of the connecting seat 5 and detachably connected to the connecting seat 5. The cosmetics in the inner cavity of the base 4 can be obtained by removing the container cover 10.

[0034] As shown in the drawings, a connecting groove 51 is provided on the outer peripheral portion of the connecting seat 5. The connecting groove 51 is formed by being recessed radially inward from the outer peripheral portion of the connecting seat 5. The connecting groove 51 has a guide portion 511 and a stop portion 512 connected along the length direction. The guide portion 511 extends in the up-down direction. The stop portion 512 is located below the guide portion 511. The connecting groove 51 opens upward from the upper end of the guide portion 511 to form an opening 51c. The inner peripheral wall of the container cover 10 is provided with a protruding portion extending outward. The connecting seat 5 has a positioning protrusion 21, which can enter or leave the connecting groove 51 through the opening 51c. When the positioning protrusion 21 is inserted in the connecting groove 51, it can slide along the length direction of the connecting groove 51. A blocking portion 52 is also provided on the outer peripheral portion of the connecting seat 5. The blocking portion 52 is provided in the connecting groove 51 and separates the guide portion 511 from the limiting portion 512, so as to block the positioning protrusion 21 from sliding along the connecting groove 51 and limit the positioning protrusion 21 in the limiting portion 512.

[0035] In this way, when the user uses the cosmetic packaging container, when the container cover 10 needs to be connected to the container body 20, the container cover 10 is sleeved on the outer peripheral portion of the connecting seat 5, and when the positioning protrusion 21 corresponds to the opening 51c, the container cover 10 is pressed downward, and the positioning protrusion 21 will move downward along the length direction of the connecting groove 51, and after passing through the guide portion 511, it will pass over the blocking portion 52 under the pressing force and enter the limiting portion 512. Due to the blocking effect of the blocking portion 52, the positioning protrusion 21 is restricted in the limiting portion 512 and cannot slide into the guiding portion 511, so that the container cover 10 and the container body 20 are fixed to each other, completing the connection of the container cover 10 on the container body 20. When the container cover 10 needs to be opened, the user pushes the container cover 10 upward, and the positioning protrusion 21 will pass over the blocking portion 52 and enter the guiding portion 511 from the limiting portion 512, and further detach from the connecting groove 51 from the opening 51c, at this time, the container cover 10 can be taken off to obtain the cosmetics for use.

[0036] In this way, when opening the container cover 10 or connecting the container cover 10, the user only needs to drive the container cover 10 up and down to open or close the container cover 10. The corresponding operation can be completed with one hand, which is more convenient to use.

[0037] Specifically, the blocking portion 52 extends along the width direction of the connecting groove 51, and the blocking portion 52 has a first side surface facing the guiding portion 511 and a second side surface facing the limiting portion 512. The first side surface gradually extends from the blocking portion 52 along the radial direction of the connecting seat 5, and is specifically an inclined surface. The second side surface extends vertically along the radial direction of the connecting seat, and is specifically a plane. This makes it easy for the positioning protrusion 21 to pass over the blocking portion 52 from the guiding portion 511 and enter the limiting portion 512, but a greater external force is required to pass over the blocking portion 52 from the limiting portion 512 and enter the guiding portion 511.

[0038] The opening 51c is in a cone shape with a larger top and a smaller bottom, and both sides of the opening are formed into inclined surfaces, so that when the container cover 10 is mounted on the connecting seat 5, the positioning protrusion 21 can enter the connecting groove 51 along the inclined surfaces on both sides of the opening 51c, making it easier to find.

[0039] The guide portion 511 includes a first guide segment 51a extending vertically in the up-down direction, and a second guide segment 51b extending obliquely downward from the first guide segment 51a, the limiting portion 512 is connected to the second guide segment 51b, and the blocking portion 52 is arranged between the second guide segment 51b and the limiting portion 512, so that the limiting portion 512 is not located directly below the opening 51c, which is more conducive to ensuring the stability of the container cover 10 and the container body 20 after being connected, and avoiding accidental opening. In the process of the positioning protrusion 21 entering from the guide portion 511 to the limiting portion 512, and in the process of the positioning protrusion 21 entering from the limiting portion 512 to the guide portion 511, the container cover 10 rotates relative to the container body 20 at a certain angle.

[0040] Furthermore, the container cover 10 includes an outer cover 1 and an inner cover 2, and a positioning protrusion 21 is provided on the inner periphery of the inner cover 2. The outer cover 1 is sleeved on the inner cover 2. In some embodiments, the outer cover 1 and the inner cover 2 are fixed to each other, so that when opening the container cover 10 or connecting the container cover 10, the user's hand can feel the relative movement of the outer cover 1. In this embodiment, the outer cover 1 can be relatively rotatably sleeved on the inner cover 2, and a limiting structure is provided between the inner cover 2 and the outer cover 1 to limit the relative rotation angle of the two. Specifically, see Figure 8 As shown, a limiting groove 22 is provided on the inner cover 2, and a limiting protrusion (not shown in the figure) is provided on the outer cover 1. The width of the limiting protrusion is smaller than the width of the limiting groove 22, and the limiting protrusion is inserted in the limiting groove 22, so that the outer cover 1 and the inner cover 2 can rotate relative to each other by a certain angle. In this way, when the user presses or pushes the container cover 10, there is no relative movement between the hand and the outer cover 1, and the experience is better.

[0041] As shown in the drawings, in the cosmetic packaging container of this embodiment, a limiting protrusion 53 is provided on the connection seat 5, and a connection groove 51 is formed on both sides of the limiting protrusion 53, wherein the guide parts 511 of the two connection grooves 51 are respectively located on different sides of the limiting protrusion 53 and are arranged in a mirror image, and the limiting parts 512 of the two connection grooves 51 overlap and are located directly below the limiting protrusion 53. The positioning protrusion 21 can enter the limiting part 512 from the opening 51c of one of the connection grooves 51 to realize the connection of the container cover 10, and the positioning protrusion 21 can enter the guide part 511 from one side of the limiting protrusion 53 to realize the opening of the container cover 10, and the positioning protrusion 21 is more likely to cooperate with the connection groove 51 to realize the opening and closing of the cover.

[0042] Upper inclined surfaces 53a are formed on both sides of the upper part of the limiting protrusion 53, which also constitute one side wall of the opening 51c; a lower plane 53b is formed at the bottom of the limiting protrusion 53, and the lower plane 53b constitutes the upper groove wall of the limiting portion 512 to provide a barrier for the upward movement of the positioning protrusion 21 when it is located in the limiting portion 512.

[0043] In this embodiment, the limiting protrusion 53, the two connecting grooves 51 and the two blocking parts 52 form a group of guide structures, and multiple groups of the above-mentioned guide structures are arranged on the connecting seat 5 at intervals along the circumferential direction; there are multiple positioning protrusions 21, the number of positioning protrusions 21 is less than or equal to the number of groups of guide structures, and the positions of the multiple positioning protrusions 21 correspond to the positions of the connecting grooves 51 on the same side of the multiple groups of guide structures. Preferably, the number of groups of guide structures is more than three groups evenly spaced along the circumferential direction, specifically three groups here, and three positioning protrusions 21 are also arranged accordingly. In this way, the interval between two adjacent groups of guide structures in the circumferential direction is small, and the positioning protrusions 21 are more likely to correspond to the connecting grooves 51, and are connected in the entire circumferential direction, thereby reducing the probability of opening the cover by mistake.

[0044] In this embodiment, as shown in the drawings, the connection seat 5 includes a connection ring 54 at the bottom, which is correspondingly inserted on the mouth of the base 4 and fixedly connected to the base 4. During manufacturing, the connection seat 5 and the base 4 are injection molded separately, and then the connection ring 54 is correspondingly inserted on the upper part of the base 4 and fixed to the base 4. Figure 2 As shown, the outer side of the connecting ring 54 is provided with a plurality of alignment protrusions 541, and the inner wall of the mouth of the base 4 is provided with a plurality of alignment grooves 41. The plurality of alignment protrusions 541 are inserted into the plurality of alignment grooves 41 one by one, and the connection can be an interference fit, so that the connecting seat 5 is fixed on the base 4. The connecting seat 5 also has an extension portion 55 extending downward from the bottom of the connecting ring 54, and the outer diameter of the extension portion is smaller than the outer diameter of the connecting ring 54. The extension portion 55 can be inserted in the inner cavity of the base 4 to make the connection between the connecting seat 5 and the base 4 more reliable.

[0045] In this embodiment, the cosmetic packaging container is a smearable packaging container, such as a lipstick tube, a lip gloss tube, etc., which also includes an inner plug 6 and an applicator rod 3. The inner plug 6 is hollow and cooperatively inserted in the connecting seat 5. One end of the applicator rod 3 is fixedly arranged on the container cover 10 and can be inserted in the inner plug 6 in an axially sliding manner. Among them, the inner plug 6 is made of a soft plastic material and has a certain elasticity. The upper end of the applicator rod 3 is fixed or integrally arranged in the inner cover 2. The upper part of the applicator rod 3 is a cone with a larger upper part and a smaller lower part. It can be cooperatively inserted in the inner plug 6, so that the container cover 10 and the container body 20 are connected to form a seal between the two to prevent the cosmetics from leaking out. Of course, in other embodiments, the cosmetic container can also be a container without an applicator rod 3, such as a packaging container for facial cream.

[0046] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
