[0004] In view of this, the present application aims to provide a powder box assembly to improve the ease of operation of pulling the inner box out of the outer shell and enhance the user experience.

[0005] To achieve the above objectives, embodiments of this application provide a powder cartridge assembly, comprising:

[0006] The outer casing has a receiving cavity and an opening communicating with the receiving cavity;

[0007] An inner box is movably disposed within the receiving cavity, at least a portion of the inner box being able to extend out of the receiving cavity through the opening, and the inner box being provided with a limiting portion;

[0008] A locking unit is disposed on the outer shell for locking with the limiting part, and the inner box and the outer shell can be unlocked by pressing the inner box in the direction of the locking unit;

[0009] One of the outer shell and the inner box is provided with a sliding groove extending in a first direction, and the other is provided with a slide rail. The inner box and the outer shell slide in cooperation with each other through the sliding groove and the slide rail.

[0010] In some embodiments, at least one pair of the slide rails and the slide grooves are disposed in a region of one-quarter to three-quarters of the powder box assembly along a second direction, wherein the first direction intersects the second direction.

[0011] In some embodiments, the outer casing has the slide rail, the inner box has the slide groove, and the locking unit is disposed on both sides of the slide rail along the second direction.

[0012] In some embodiments, the outer casing includes a first sub-shell and a second sub-shell, which together define the receiving cavity. The bottom wall of the first sub-shell protrudes along the thickness direction of the powder cartridge assembly to form the slide rail. The thickness direction of the powder cartridge assembly intersects with the first direction and the second direction, respectively.

[0013] In some embodiments, the inner box protrudes on one side along the thickness direction of the powder box assembly to form a protrusion, so that the other side of the inner box is recessed to form a receiving groove for accommodating cosmetics, and at least a portion of the sidewall of the protrusion constitutes at least a portion of the groove wall of the slide.

[0014] In some embodiments, the inner box extends toward the locking unit along the first direction to form a reinforcing portion, the reinforcing portion forming at least a portion of the groove.

[0015] In some embodiments, the housing is provided with a clearance opening that communicates with the opening and is located in a region of one-quarter to three-quarters of the powder cartridge assembly along the second direction.

[0016] In some embodiments, the inner box is provided with the limiting protrusion on at least one end sidewall along the second direction, the limiting protrusion being used to abut against the outer shell when the inner box extends out of the receiving cavity to its maximum stroke.

[0017] In some embodiments, the outer casing is provided with a limiting groove, and the limiting protrusion engages with the limiting groove when the inner box extends out of the receiving cavity to its maximum stroke.

[0018] In some embodiments, the cavity wall of the receiving cavity protrudes to form a protrusion, the protrusion and the cavity wall of the receiving cavity located partially at the opening define the limiting groove, the dimension of the protrusion along the second direction being smaller than the dimension of the groove wall of the limiting groove on the side near the opening along the second direction.

[0019] The powder cartridge assembly provided in this application, on the one hand, allows the locking unit to switch between locked and unlocked states by pressing the inner cartridge towards the locking unit, thereby fixing or removing the inner cartridge from the receiving cavity, making the user's operation simpler and less strenuous, and improving the user experience. On the other hand, by providing a sliding groove and a sliding rail on the outer shell and the inner cartridge respectively, the inner cartridge and the outer shell slide together through the sliding groove and the sliding rail, thereby guiding the inner cartridge to extend and retract into the receiving cavity, increasing the structural strength at the sliding rail, and improving the situation where the inner cartridge is prone to deformation during pressing.

[0030] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0031] In the description of the embodiments of this application, it should be noted that the terms "upper," "lower," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0033] Cosmetics can enhance people's life experience. In addition to the function of the cosmetics themselves, the ease of use of the outer packaging is also an important factor for users when choosing cosmetics.

[0034] In related technologies, the inner box of a drawer-type powder box assembly can be pulled out from the outer shell for users to access cosmetics located on the inner box. However, the inner box usually needs to be pulled out manually, which is laborious and cumbersome, reducing the user's experience.

[0035] Based on the above, this application provides a powder cartridge assembly 10. Please refer to [link / reference]. Figures 1 to 8 The powder cartridge assembly 10 includes a housing 11, an inner cartridge 12, and a locking unit 13. The housing 11 has a receiving cavity 11a and an opening 11b communicating with the receiving cavity 11a. The inner cartridge 12 is movably disposed within the receiving cavity 11a. At least a portion of the inner cartridge 12 can extend out of the receiving cavity 11a through the opening 11b. The inner cartridge 12 is provided with a limiting portion 12a. The locking unit 13 is disposed on the housing 11 for locking engagement with the limiting portion 12a, and can be released by pressing the inner cartridge 12 toward the locking unit 13. One of the housing 11 and the inner cartridge 12 is provided with a groove 12b extending in a first direction, and the other is provided with a slide rail 11c, through which the inner cartridge 12 and the housing 11 slide in engagement via the groove 12b and the slide rail 11c.

[0036] The outer shell 11 has a receiving cavity 11a and an opening 11b communicating with the receiving cavity 11a. The inner box 12 is movably disposed in the receiving cavity 11a, meaning that the powder box assembly 10 is a drawer type. The inner box 12 can be pulled out from the receiving cavity 11a for the user to use the cosmetics 14 located on the inner box 12. The inner box 12 can also be stored in the receiving cavity 11a so that the outer shell 11 can protect and store the cosmetics 14 on the inner box 12, and also make the powder box assembly 10 easier to carry.

[0037] At least a portion of the inner box 12 can extend out of the receiving cavity 11a through the opening 11b, that is, the inner box 12 can extend completely out of the receiving cavity 11a or partially out of the receiving cavity 11a.

[0038] When the inner box 12 extends out of the receiving cavity 11a, the inner box 12 cannot be detached from the receiving cavity 11a, and the inner box 12 and the outer shell 11 are inseparable.

[0039] The locking unit 13 provided on the outer shell 11 locks with the limiting part 12a provided on the inner box 12, thereby realizing the interlock between the outer shell 11 and the inner box 12. At this time, the inner box 12 is fixed inside the outer shell 11, which can prevent the inner box 12 from sliding out of the receiving cavity 11a through the opening 11b, making it convenient to carry the powder box assembly 10.

[0040] It should be noted that the locking unit 13 has an unlocked state and a locked state.

[0041] By pressing the inner box 12 toward the locking unit 13, the inner box 12 and the outer shell 11 can be unlocked, thus disabling the locking engagement between the locking unit 13 and the limiting part 12a. Here, by pressing the inner box 12 toward the locking unit 13, the locking unit 13 can also be locked into the limiting part 12a, thereby achieving a lock between the inner box 12 and the outer shell 11.

[0042] Thus, by simply pressing the inner box 12 toward the locking unit 13, the locking unit 13 can be switched between the locked and unlocked states, thereby fixing or pulling the inner box 12 out of the receiving cavity 11a, making the user's operation simpler and less strenuous, and improving the user's experience.

[0043] For example, the powder box assembly 10 is generally rectangular, and the first direction is the width direction of the powder box assembly 10.

[0044] For example, the locking unit 13 is a bouncer.

[0045] For example, the locking unit 13 includes a main body 131 and a claw 132. The claw 132 is disposed at the end of the main body 131 near the opening 11b along a first direction. The claw 132 is slidable relative to the main body 131 along the first direction and is used to engage with the limiting part 12a. In the unlocked state, an external force along the first direction drives the inner box 12 to press inward. The limiting part 12a contacts and drives the claw 132 to move toward the main body 131. The main body 131 locks the claw 132 in a first position. At the same time, the claw 132... The limiting part 12a is kept closed and locked, thereby switching to the locked state. In the locked state, by applying an external force along the first direction, the limiting part 12a is driven to press the claw 132 inward along the first direction. The claw 132 moves toward the main body 131. The main body 131 releases the locking of the claw 132 in the first position and pops the claw 132 out toward the opening 11b along the first direction. The main body 131 locks the claw 132 in the second position. At the same time, the claw 132 opens, and the limiting part separates from the claw 132, thereby switching to the unlocked state.

[0046] One of the outer shell 11 and the inner box 12 is provided with a sliding groove 12b extending along a first direction, and the other is provided with a slide rail 11c. The inner box 12 and the outer shell 11 are slidably engaged by the sliding groove 12b and the slide rail 11c. The first direction is the extension direction of the inner box 12. The sliding groove 12b and the slide rail 11c are used to guide the extension and retraction of the inner box 12 into the receiving cavity 11a, increase the structural strength at the slide rail 11c, and improve the situation where the inner box 12 is prone to deformation during the pressing process.

[0047] The powder cartridge assembly 10 provided in this application embodiment, on the one hand, allows the locking unit 13 to switch between a locked state and an unlocked state by pressing the inner cartridge 12 toward the locking unit 13, thereby fixing or pulling the inner cartridge 12 out of the receiving cavity 11a, making the user's operation simpler and less strenuous, and improving the user experience. On the other hand, by providing a sliding groove 12b and a sliding rail 11c on the outer shell 11 and the inner cartridge 12 respectively, the inner cartridge 12 and the outer shell 11 slide together through the sliding groove 12b and the sliding rail 11c, thereby guiding the inner cartridge 12 to extend and retract into the receiving cavity 11a, increasing the structural strength at the sliding rail 11c, and improving the situation where the inner cartridge 12 is prone to deformation during pressing.

[0048] In some embodiments, please refer to Figure 4 and Figure 5 At least one pair of slide rails 11c and slide grooves 12b are disposed in a region of the powder box assembly 10 along a second direction, covering one-quarter to three-quarters of the area. The first direction intersects the second direction.

[0049] For example, the powder box assembly 10 is generally rectangular, with the first direction being the width direction of the powder box assembly 10 and the second direction being the length direction of the powder box assembly 10.

[0050] At least one pair of slide rails 11c and slide grooves 12b are disposed in the area of ​​the powder cartridge assembly 10 in the second direction, which means that the slide rails 11c and slide grooves 12b are disposed in the middle area of ​​the powder cartridge assembly 10 in the second direction.

[0051] Specifically, such as Figure 5 As shown, the overall dimension of the powder box assembly 10 along the second direction is represented by a, and the distance between the setting position of the slide rail 11c and the slide groove 12b and any end of the powder box assembly 10 along the second direction is represented by b. With a as the reference, the ratio of b to a ranges from one-quarter to three-quarters, that is, from 25% to 75%.

[0052] For example, the ratio of b to a can be 25%, 30%, 40%, 50%, 60%, 70%, or 75%, etc., and there is no limitation here.

[0053] It should be noted that the number of pairs of slide rails 11c and slide grooves 12b located in the area of ​​the powder box assembly 10 along the second direction of one-quarter to three-quarters can be one or more pairs, and there is no limitation here.

[0054] It is understandable that the slide rail 11c and the slide groove 12b can also be located outside the area of ​​the powder box assembly 10 along the second direction, which is not limited here.

[0055] The "multiple or multiple pairs" mentioned in the embodiments of this application refer to a quantity of two or more.

[0056] Thus, by setting at least one pair of slide rails 11c and slide grooves 12b in the area of ​​the powder cartridge assembly 10 along the second direction, such that the slide rails 11c and slide grooves 12b are located in the middle area of ​​the powder cartridge assembly 10 along the second direction, the structural strength of the inner box 12 and the outer shell 11 can be improved, thereby improving the stability and reliability of the inner box 12 sliding along the first direction, increasing the deformation resistance of the inner box 12 during pressing and sliding, and increasing the durability and service life of the powder cartridge assembly 10.

[0057] In some embodiments, please refer to Figures 4 to 7 The outer casing 11 has a slide rail 11c. The inner box 12 has a slide groove 12b. Locking units 13 are disposed on both sides of the slide rail 11c along the second direction.

[0058] Locking units 13 are disposed on both sides of slide rail 11c along the second direction, meaning there are at least two locking units 13. The two locking units 13 can increase the locking force on the inner box 12. At the same time, the slide rail 11c is located between the locking units 13, and the sliding cooperation between the slide rail 11c and the slide groove 12b can improve the accuracy of the docking between the locking units 13 on both sides and the limiting block, thereby improving the reliability of locking.

[0059] In some embodiments, please refer to Figures 1 to 3 The outer casing 11 includes a first sub-shell 111 and a second sub-shell 112. The first sub-shell 111 and the second sub-shell 112 together define a receiving cavity 11a. The bottom wall of the first sub-shell 111 protrudes along the thickness direction of the powder cartridge assembly 10 to form a slide rail 11c. The thickness direction of the powder cartridge assembly 10 intersects with a first direction and a second direction, respectively.

[0060] For example, the first direction is the width direction of the powder box assembly 10, the second direction is the length direction of the powder box assembly 10, and the thickness direction of the powder box assembly 10 is perpendicular to both the first and second directions.

[0061] For example, a portion of the opening 11b is formed in the first sub-shell 111 and another portion is formed in the second sub-shell 112. The first sub-shell 111 and the second sub-shell 112 are joined together in the height direction to jointly define the opening 11b.

[0062] Here, the outer shell 11 is divided into a first sub-shell 111 and a second sub-shell 112, which facilitates the assembly of the powder cartridge assembly 10. The bottom wall of the first sub-shell 111 protrudes along the thickness direction of the powder cartridge assembly 10 to form a slide rail 11c, which facilitates the integral processing of the slide rail 11c and the first sub-shell 111 and can increase the connection strength between the slide rail 11c and the first sub-shell 111.

[0063] In some embodiments, please refer to Figure 3 and Figure 6 The inner box 12 protrudes from one side along the thickness direction of the powder box assembly 10 to form a protrusion 12c, so that the other side of the inner box 12 is recessed to form a receiving groove 12d for accommodating cosmetic 14. At least a portion of the sidewall of the protrusion 12c constitutes at least a portion of the groove wall of the slide 12b.

[0064] The inner box 12 protrudes along one side of the powder box assembly 10 in the thickness direction to form a protrusion 12c, so that the other side of the inner box 12 is recessed to form a receiving groove 12d for accommodating cosmetics 14. That is, the position of the receiving groove 12d corresponds to the position of the protrusion 12c. The protrusion 12c can avoid the space of the receiving groove 12d, making the structure of the inner box 12 more reasonable and improving the utilization rate of the material and space of the inner box 12.

[0065] The statement that at least a portion of the sidewall of the protrusion 12c constitutes at least a portion of the groove wall of the slide 12b means that at least a portion of the sidewall of the protrusion 12c extending in the first direction constitutes at least a portion of the groove wall of the slide 12b. This includes the case where the entire sidewall of the protrusion 12c extending in the first direction constitutes a portion of the groove wall of the slide 12b.

[0066] For example, the sidewall between two adjacent protrusions 12c along the second direction defines a portion of the groove wall of the slide 12b.

[0067] For example, the protrusions 12c are spaced apart along the second direction, and the inner box 12 is also provided with reinforcing ribs. At least a portion of the sidewall of the protrusion 12c along the second and first directions is spaced apart from the sidewall of the inner box 12. A portion of the reinforcing ribs are disposed between the sidewall of the inner box 12 and the sidewall of the protrusion 12c to connect the sidewall of the inner box 12 and the sidewall of the protrusion 12c respectively, thereby increasing the structural strength of the inner box 12. A portion of the reinforcing ribs are disposed between two adjacent protrusions 12c, with one end along the second direction connected to the sidewall of the protrusion 12c and the other end spaced apart from the sidewall of the adjacent protrusion 12c. Thus, the sliding groove 12b is defined by the reinforcing ribs and the sidewall of the protrusion 12c. In this way, when the inner box 12 slides along the first direction, the slide rail 11c is in contact with the sidewall of the protrusion 12c on one side along the second direction and with the reinforcing rib on the other side. This not only improves the structural strength of the inner box 12, but also reduces the material and weight of the inner box 12, which is beneficial for carrying the powder box assembly 10.

[0068] In this way, the protrusion 12c of the inner box 12 can form at least part of the groove wall of the slide groove 12b, while also avoiding the space of the receiving groove 12d. The structure of the protrusion 12c is rationally utilized, making the structure of the inner box 12 more rational and improving the utilization rate of the material and space of the inner box 12.

[0069] In some embodiments, please refer to Figures 4 to 7 The inner box 12 extends toward the locking unit 13 along the first direction to form a reinforcing portion 12e. The reinforcing portion 12e forms at least a partial groove 12b.

[0070] On the one hand, the reinforcing part 12e, on which the groove 12b is formed, can increase the cooperation stroke between the groove 12b and the slide rail 11c, increase the contact area of ​​the sliding cooperation, and improve the sliding stability of the inner box 12 when it slides out of the outer shell 11 to the maximum stroke. On the other hand, the reinforcing part 12e can improve the structural strength of the inner box 12 on the side close to the locking unit 13 along the first direction, and reduce the probability that the inner box 12 is prone to deformation on the side close to the locking unit 13 along the first direction.

[0071] In some embodiments, please refer to Figures 1 to 5The outer casing 11 is provided with a clearance opening 11d. The clearance opening 11d communicates with the opening 11b. The clearance opening 11d is located in the area of ​​the powder cartridge assembly 10 from one-quarter to three-quarters along the second direction.

[0072] The connection between the clearance opening 11d and the opening 11b means that the end of the clearance opening 11d near the opening 11b is connected to the opening 11b.

[0073] During the process of the user pressing the inner box 12, the avoidance opening 11d can avoid the user's fingers, which can improve the interference between the user's fingers and the outer shell 11 when pressing, increase the contact area between the fingers and the inner box 12, and make it easier for the user to apply pressing pressure.

[0074] The clearance opening 11d is located in the area of ​​the powder cartridge assembly 10 along the second direction, from one-quarter to three-quarters. That is, the clearance opening 11d is positioned to correspond to the slide groove 12b and slide rail 11c located in the area of ​​the powder cartridge assembly 10 along the second direction, thereby guiding the user to press the inner box 12 at the clearance opening 11d, improving the stress situation of the slide groove 12b and slide rail 11c in the area of ​​the powder cartridge assembly 10 along the second direction, and reducing the stress concentration of the inner box 12.

[0075] In some embodiments, please refer to Figures 5 to 8 The inner box 12 has a limiting protrusion 12f on at least one end sidewall along the second direction. The limiting protrusion 12f is used to abut against the outer shell 11 when the inner box 12 is extended out of the receiving cavity 11a to the maximum stroke.

[0076] It should be noted that on a plane perpendicular to the first direction, a portion of the inner box 12 that can extend out of the receiving cavity 11a through the opening 11b has its projection located within the projection of the opening 11b, thereby allowing the inner box 12 to extend smoothly.

[0077] The limiting protrusion 12f is used to abut against the outer shell 11 when the inner box 12 is extended out of the receiving cavity 11a to the maximum stroke. This means that on a plane perpendicular to the first direction, the projection of the limiting protrusion 12f provided on the inner box 12 is outside the projection of the opening 11b, so that when the inner box 12 is extended out of the receiving cavity 11a to the maximum stroke, the limiting protrusion 12f interferes with the outer shell 11 at the opening 11b, preventing the inner box 12 from completely coming out of the receiving cavity 11a.

[0078] This improves the overall integrity of the powder box assembly 10 and reduces the risk of the inner box 12 being lost after it is completely separated from the outer shell 11.

[0079] In some embodiments, please refer to Figures 5 to 8 The outer casing 11 is provided with a limiting groove 11e. When the inner box 12 extends out of the receiving cavity 11a to its maximum stroke, the limiting protrusion 12f engages with the limiting groove 11e.

[0080] The outer shell 11 is provided with a limiting groove 11e. When the inner box 12 extends out of the receiving cavity 11a to its maximum stroke, the limiting protrusion 12f will abut against the outer shell 11 at the opening 11b, that is, against the cavity wall of the receiving cavity 11a at the opening 11b. In other words, at least a portion of the cavity wall of the receiving cavity 11a at the opening 11b constitutes the groove wall of the limiting groove 11e on the side of the first direction close to the opening 11b. The limiting groove 11e limits the limiting protrusion 12f along the groove wall of the first direction close to the opening 11b, preventing the inner box 12 from completely detaching from the receiving cavity 11a.

[0081] The limiting groove 11e is located on the side of the groove away from the opening 11b in the first direction, so that when the inner box 12 of the powder box assembly 10 extends out of the receiving cavity 11a to the maximum stroke, the inner box 12 is not easy to retract into the receiving cavity 11a due to accidental contact, thus improving the user experience of the powder box assembly 10.

[0082] Therefore, the limiting groove 11e has a certain locking force on the limiting protrusion 12f, which makes it easier for the user to sense that the inner box 12 has reached its maximum stroke. At the same time, when the inner box 12 is extended out of the receiving cavity 11a to its maximum stroke, the inner box 12 is not easy to retract into the receiving cavity 11a when the user takes out the cosmetics 14 on the inner box 12, thus improving the user experience of the powder box assembly 10.

[0083] In some embodiments, please refer to Figures 7 to 8 The cavity wall of the receiving cavity 11a protrudes to form a protrusion 11f. The protrusion 11f and the cavity wall of the receiving cavity 11a, which is partially located at the opening 11b, define a limiting groove 11e. The dimension of the protrusion 11f in the second direction is smaller than the dimension of the groove wall of the limiting groove 11e on the side near the opening 11b in the second direction.

[0084] The cavity wall of the receiving cavity 11a protrudes to form a protrusion 11f. The protrusion 11f and the cavity wall of the receiving cavity 11a located at the opening 11b define a limiting groove 11e. This means that when the inner box 12 is not extended out of the receiving cavity 11a to its maximum stroke, there is no contact between the cavity wall of the receiving cavity 11a and the limiting protrusion 12f. This makes it less likely for the limiting protrusion 12f to scratch the cavity wall of the receiving cavity 11a, reducing the sliding resistance between the inner box 12 and the outer shell 11, and improving the smoothness of the sliding of the inner box 12.

[0085] It is understandable that the larger the size of the protrusion 11f along the second direction, the greater the locking force of the limiting groove 11e on the limiting protrusion 12f. By setting the size of the protrusion 11f along the second direction to be smaller than the size of the groove wall of the limiting groove 11e near the opening 11b along the second direction, the elastic deformation required for the limiting protrusion 12f to enter the limiting groove 11e is smaller, and the locking force of the protrusion 11f on the limiting protrusion 12f is within a reasonable range. This makes it easier for the user to perceive that the inner box 12 has reached its maximum stroke, while making the user's operation more effortless and improving the user experience.

[0086] For example, the protrusion 11f has a guide surface formed on at least one side along the first direction. The guide surface facilitates the entry or exit of the limiting protrusion 12f into the limiting groove 11e and reduces the clamping force of the limiting groove 11e on the limiting protrusion 12f.

[0087] In some embodiments, please refer to Figure 7 The maximum value of the ratio of the dimension of the slide rail 11c along the first direction to the dimension of the housing 11 along the first direction is in the range of 0.8 to 0.9.

[0088] For example, the maximum value of the ratio of the dimension of the slide rail 11c along the first direction to the dimension of the housing 11 along the first direction is in the range of 0.8, 0.82, 0.85, 0.86, 0.88 or 0.9, etc., and is not limited here.

[0089] It should be noted that, as Figure 7 As shown, the overall dimension of the outer shell 11 along the first direction is represented by c, and the dimension of the slide rail 11c along the first direction is represented by d. With c as the reference, the maximum value of the ratio of d to c is 0.8 to 0.9, that is, 80% to 90%.

[0090] By setting the maximum value of the ratio of the dimension of the slide rail 11c along the first direction to the dimension of the outer shell 11 along the first direction to be between 0.8 and 0.9, the slide rail 11c can be made as long as possible, increasing the cooperation stroke between the slide rail 11c and the slide groove 12b, improving the guidance of the inner box 12 sliding along the first direction, and also improving the interference between the inner box 12 and the slide rail 11c when the inner box 12 is pressed.
