Description

Technical Field

[0001] This utility model relates to a powder box container, specifically, to a convenient replacement powder box container. Background Technology

[0002] Foundation and other cosmetics are typically packaged in compact powder containers. These containers, also known as "compact powder boxes," generally have a simple structure: the lower housing holds the contents (cosmetics), while the upper housing is hinged to the lower housing. Powder products often have a powder puff on top, and a mirror is usually installed on the inside of the upper housing.

[0003] The simple hinge structure used in typical powder compact containers has a limited range of rotation. Due to this limitation, the maximum angle achievable between the upper and lower shells is typically only about 120 to 140 degrees. Since users usually look through a mirror on the inside of the upper shell to access the contents, expanding the rotation range of the upper shell would significantly improve user convenience. However, if a simple hinge structure were used to achieve a 180-degree rotation range, the hinge would protrude significantly towards the rear of the powder compact, potentially detracting from its aesthetics. A sophisticated appearance is important in all products, but it is especially crucial in the cosmetics industry; therefore, even products designed for user convenience must maintain a refined and elegant appearance.

[0004] On the other hand, a single powder compact container can only hold a limited amount of product. If the container is discarded after use, the effort put into achieving its sophisticated appearance can result in considerable waste. Making the powder compact container replaceable allows for refilling even after use, offering the advantage of continuing to use the elegantly designed cosmetic container while avoiding significant waste. In replaceable cosmetic containers, it is preferable to configure the replacement unit, which is normally intact but easily detachable when needed. However, achieving this balance in small cosmetic containers like powder compacts can be challenging. If the replacement unit is securely fixed, it may be difficult to detach when needed; conversely, if it is easily detachable, it may detach unintentionally. Utility Model Content

[0005] Therefore, this utility model is proposed to solve the above-mentioned problems. One aspect of this utility model is to provide a powder box container that can significantly expand the rotation range of the upper shell relative to the lower shell while maintaining an elegant appearance.

[0006] Another aspect of this invention is to provide a replaceable powder box container that securely fixes the replacement unit under normal conditions, while allowing the replacement unit to be easily separated when needed.

[0007] Other objectives of this invention will become clearer through the embodiments described below.

[0008] The technical solution of this utility model for solving the above-mentioned problems is as follows.

[0009] This utility model provides a powder box container, comprising: a lower frame having a first hinge portion; an upper frame having a second hinge portion; and a hinge support having a shielding portion that shields the outer sides of the first hinge portion and the second hinge portion, rotatably coupled to the first hinge portion about a first rotation axis, and rotatably coupled to the second hinge portion about a second rotation axis. The inner surface of the shielding portion includes a flat surface with a flat shape and an arc surface with an arc-shaped cross section. The first hinge portion and the second hinge portion each include a flat portion with a flat surface and an arc portion with an arc-shaped cross section. The upper frame is overlapped with the lower frame in a closed position, and the flat portions of the first hinge portion and the second hinge portion are adjacent to the flat surface of the shielding portion.

[0010] The first hinge portion is formed on the hinge beam. When the hinge bracket rotates at a pre-designed angle relative to the first hinge portion, the end of the shielding portion contacts the hinge beam.

[0011] The pre-designed angle is 90 degrees.

[0012] The first frictional force resisting the relative rotation of the first hinge portion relative to the hinge support is less than the second frictional force resisting the relative rotation of the second hinge portion relative to the hinge support.

[0013] The hinge bracket further includes a bracket body in which the first hinge portion and the second hinge portion can be rotatably coupled. A guide groove is formed on the surface of the bracket body facing the first hinge portion. The first hinge portion also includes a boss protruding towards the bracket body. When the first hinge portion is coupled to the hinge bracket, the boss is inserted into the guide groove.

[0014] The inner surface of the support body includes a flat surface with a flat shape. When the upper frame is rotated 180 degrees from the closed position, the flat surface of the inner surface of the support body is exposed upward between the upper frame and the lower frame.

[0015] The lower frame has a pair of first hinge parts, the upper frame has a pair of second hinge parts, and the bracket body is connected between the pair of first hinge parts and the pair of second hinge parts.

[0016] The outer surface of the shielding part includes a flat surface with a flat shape and an arc surface with an arc-shaped cross section.

[0017] The effects of this utility model are as follows.

[0018] Based on the technical solution of this utility model as described above, various effects, including the following, are expected to be achieved. However, it should be noted that this utility model does not necessarily require all of the following effects to be realized.

[0019] According to some embodiments of the present invention, a powder box container with a double-hinge structure is provided, wherein the upper shell and the lower shell are rotatably connected to the hinge bracket.

[0020] The hinge bracket and hinge structure in this powder box container allow the upper shell to move accurately to a 90-degree open position, a 180-degree open position, and a closed position. In particular, in the 180-degree open position, the bracket body of the hinge bracket can be exposed both upwards and downwards, thus making it highly usable as a design element.

[0021] On the other hand, according to some embodiments of this utility model, a powder cartridge container is provided that securely fixes the replacement unit during normal use, making accidental separation extremely unlikely. When a user of this powder cartridge container wants to separate the replacement unit, the replacement unit can be released by simply opening the upper housing to a 180-degree unfolded position, grasping the exposed hinge brackets at the top and bottom, and pulling the sliding base.

Detailed Implementation

[0044] This utility model can be modified in many ways and has many embodiments; therefore, specific embodiments are illustrated in the accompanying drawings and described in detail in the description. However, this is not intended to limit the utility model to the specific implementation, but should be understood to include all modifications, equivalents, and even substitutions falling within the spirit and technical scope of this utility model. In describing this utility model, detailed descriptions of relevant prior art are omitted when it is determined that specific descriptions of such art may obscure the main points of this utility model.

[0045] The terminology used in this application is for illustrative purposes only and is not intended to limit the scope of the invention. Unless explicitly defined differently in the context, singular expressions include plural forms. In this application, terms such as "comprising" or "having" are intended to specify the presence of features, numbers, steps, actions, constituent elements, components, or combinations thereof described in the specification, and should not be construed as pre-excluding the possibility of the presence or addition of one or more other features, numbers, steps, actions, constituent elements, components, or combinations thereof.

[0046] Terms such as “first” and “second” can be used to describe multiple constituent elements, but these constituent elements should not be limited by these terms. These terms are used only for the purpose of distinguishing one constituent element from other constituent elements.

[0047] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the description with reference to the drawings, the same or corresponding constituent elements are assigned the same reference numerals, regardless of the reference numerals, and repeated descriptions thereof are omitted.

[0048] For ease of explanation, this manual uses terms such as "front," "rear," "left and right," "side," "horizontal," "inner," "outer," "upper," and "lower." In the following description, "front," "rear," and "left and right" are based on the direction in which the sliding base 100 of the toner cartridge container 100 is pulled is considered to be forward. "Side" encompasses both left and right sides, and "horizontal" encompasses both front-back and left-right directions. "Inner" refers to the side closest to the object being described or the interior of the toner cartridge container 1000, and "outer" refers to the side furthest from the object being described or the interior of the toner cartridge container 1000. "Upper" and "lower" are defined with the toner cartridge container 1000 as shown in the image. Figures 1(a) to 4 The configuration shown is a baseline. Of course, in actual use of the powder box container 1000 of one embodiment of this utility model, the front-back, left-right, and up-down directions described in the specification may not be consistent with the actual front-back and up-down directions.

[0049] One embodiment of the powder cartridge container 1000 of this utility model aims to use a sliding structure to securely fix the replacement unit under normal conditions, while allowing the replacement unit to be easily detached when needed. Furthermore, the powder cartridge container 1000 utilizes a double-hinge structure, allowing the upper housing to rotate at an angle that maximizes user convenience.

[0050] Figures 1(a) and 1(b) are perspective views illustrating a powder container 1000 according to an embodiment of the present invention. Figure 1(a) depicts the upper part, front (front side) and left side of the powder container 1000, and Figure 1(b) depicts the upper part, left side and back (rear side) of the powder container 1000. Figure 2 This is an exploded 3D view of the powder box container 1000. Figure 3 and Figure 4 This is a cross-sectional view of the powder box container 1000. Figures 5 to 15 The components of the powder box container 1000 are shown in further detail.

[0051] Reference Figures 1(a) to 15 A powder box container 1000 according to one embodiment of the present invention generally includes a sliding base 100, a lower frame 200, a unit container 300, a retaining ring 400, a unit cover 500, an upper frame 600, a cover 700, and a hinge bracket 800. The sliding base 100 and the lower frame 200 can constitute a lower shell, the unit container 300, the retaining ring 400, and the unit cover 500 can constitute a replacement unit, and the upper frame 600 and the cover 700 can constitute an upper shell.

[0052] The sliding base 100 is part of the lower housing and constitutes part (lower part) of the overall appearance of the powder container 1000. The sliding base 100 is also slidably attached to the lower frame 200. Specifically, the sliding base 100 is configured to slide relative to the lower frame 200 in a front-rear direction within a range of motion including a first position and a second position. Here, the "first position" corresponds to the position where the replacement unit is fixed, and the "second position" corresponds to the position where the replacement unit can be separated.

[0053] Figure 5 A sliding base 100 of a powder box container 1000 according to an embodiment of the present invention is shown in further detail. For example... Figures 2 to 5 As shown, the sliding base 100 may include a base plate 110, a front wall 120, a side wall 140, locking protrusions 152 and 154, a cross rail 162 and 163, and limiting protrusions 172 and 173.

[0054] The base plate 110 can form the lower part of the sliding base 100. The bottom surface of the base plate 110 can form the bottom surface of the powder box container 1000.

[0055] The front wall 120 extends upward from the base plate 110 on the front side of the sliding base 100. Depending on the needs, the front wall 120 may be provided with components for the detachable connection of the upper and lower housings. For example, in the illustrated example, the inner side of the front wall 120 is provided with a support step 126 for placing a magnetic object (not shown). Here, the magnetic objects in the upper and lower housings refer to two objects that exert an attractive force on each other through magnetic interaction. Both the upper and lower housings may be magnets, or only one may be a magnet.

[0056] The support step 126 allows the magnetic body (not shown) to be supported at an upper position near the lower housing, thereby enabling it to interact more easily with a corresponding magnetic body (not shown) located on the upper housing. The support step 126 can extend inward from the inner surface of the front wall 120, and preferably, even when the sliding base 100 is pulled forward, a portion of the support step 126 can still extend to support the magnetic body (not shown).

[0057] The sidewall 140 may extend upward from the base plate 110 on the side of the sliding base 100. In the illustrated example, the sidewall 140 of the sliding base 100 is located outside the outer wall 240 of the lower frame 200.

[0058] The slidable base 100 and the lower frame 200 each include sliding portions corresponding to parts that interact with each other in a manner that allows the slidable base 100 and the lower frame 200 to slide relative to each other. To distinguish between the sliding portions of the slidable base 100 and the lower frame 200, the sliding portion of the lower frame 200 is referred to as the first sliding portion, and the sliding portion of the slidable base 100 is referred to as the second sliding portion. In the illustrated example, the sidewall 140 of the slidable base 100 corresponds to the second sliding portion, and therefore the cross rails 162, 163 and the limiting protrusions 172, 173 are formed on the sidewall 140. Of course, in other embodiments not illustrated, the base plate 110 may function as the second sliding portion, or a separate component provided on the base plate 110 or the sidewall 140 may function as the second sliding portion. In this case, the cross rails 162, 163 and the limiting protrusions 172, 173 may also be formed on this sliding portion.

[0059] Furthermore, in the illustrated example, the sidewall 140 of the sliding base 100 is located outside the outer wall 240 of the lower frame 200, and the cross rails 162, 163 and the limiting protrusions 172, 173 are provided on the inner surface of the sidewall 140. However, in some other embodiments not illustrated, the sidewall 140 of the sliding base 100 may also be located inside the outer wall 240 of the lower frame 200. In this case, similarly, the cross rails 162, 163 and the limiting protrusions 172, 173, as parts corresponding to the sliding portion, may also be provided on the outer surface of the sidewall 140.

[0060] The locking protrusions 152 and 154 can be configured as fixed protrusions 352 and 354 of the unit container 300, depending on the position of the sliding base 100. Therefore, the locking protrusions 152 and 154 can protrude horizontally at positions corresponding to the fixed protrusions 352 and 354. In the illustrated example, the locking protrusions 152 and 154 are formed on the top of the base plate 110 of the sliding base 100, and thus protrude upwards and then horizontally. Of course, the locking protrusions 152 and 154 can also be formed at positions other than the base plate 110, and depending on their location, they may not protrude upwards but only horizontally.

[0061] The horizontal rails 162 and 163 can be used to slidably attach the slidable base 100 to the lower frame 200. The horizontal rails 162 and 163 can be configured to insert into the guide groove 260. The horizontal rails 162 and 163 can be included in one of the first sliding portion and the second sliding portion, and the guide groove 260 can be included in the other of the first sliding portion and the second sliding portion. That is, in the illustrated example, the horizontal rails 162 and 163 are formed on the inner surface of the sidewall 140 corresponding to the second sliding portion, but if the position of the second sliding portion in the slidable base 100 changes, the position of the horizontal rails 162 and 163 may also change. Furthermore, in some embodiments, the horizontal rails 162 and 163 can be formed in the lower frame 200, while the guide groove 260 can be formed in the slidable base 100.

[0062] According to one embodiment of the present invention, in each second sliding portion of the slidable base 100, a cross rail 162 may be formed at a predetermined position on the front side, and another cross rail 163 may be formed at a predetermined position on the rear side. This helps the slidable base 100 maintain a horizontal position throughout its entire range of motion. Of course, a cross rail may also extend relatively long over the entire sliding portion. When the front cross rail 162 and the rear cross rail 163 are formed in the sliding portion, limiting protrusions 172, 173 or locking protrusions 270 may also be formed between the two cross rails 163.

[0063] The limiting protrusions 172 and 173 can be used to detachably fix the slidable base 100 to the lower frame 200. The limiting protrusions 172 and 173 can be configured to engage with the locking protrusion 270. The limiting protrusions 172 and 173 can be included in one of the first sliding portion and the second sliding portion, and the locking protrusion 270 can be included in the other of the first sliding portion and the second sliding portion. That is, in the illustrated example, the limiting protrusions 172 and 173 are formed on the inner surface of the sidewall 140 corresponding to the second sliding portion, but if the position of the second sliding portion in the slidable base 100 changes, the position of the limiting protrusions 172 and 173 may also change. Furthermore, in some embodiments, the limiting protrusions 172 and 173 may be formed in the lower frame 200, while the locking protrusion 270 may be formed in the slidable base 100.

[0064] According to one embodiment of the present invention, in each second sliding portion of the slidable base 100, limiting protrusions 172 and 173 are formed in pairs, thereby forming a limiting groove 175 therebetween. In the illustrated example, when the slidable base 100 is in a first position relative to the lower frame 200, a locking protrusion 270 is inserted into the limiting groove 175 for fixation. Thus, one locking protrusion 270 is inserted into the limiting groove 175 and contacts the limiting protrusions 172 and 173 on the front and rear sides respectively, so that the locking protrusion 270 can be firmly fixed. However, depending on the range and direction of movement of the slidable base 100, only one limiting protrusion 173 may be used. In addition to the first position, the structure of the limiting protrusions 172 and 173 may also be formed at points corresponding to the second position.

[0065] The lower frame 200 can form a lower housing together with the slidable base 100, as previously described, the slidable base 100 and the lower frame 200 can be slidably coupled relative to each other. Figure 6 and Figure 7 These are, respectively, a perspective view and a bottom view of the lower frame 200 of a powder box container 1000 according to an embodiment of this utility model. Figure 6 and Figure 7 As shown, the lower frame 200 may include an upper frame 210, a frame sidewall 220, an outer wall 240, guide rails 262 and 264, a locking protrusion 270, a stop protrusion 280, and a first hinge portion 290.

[0066] The upper frame 210 may form the upper part of the lower frame 200. When the upper housing is rotated open from the lower housing for use of the powder container 1000, all or part of the upper frame 210 may be exposed to the user and may surround the through hole 250 for accessing the contents (not shown).

[0067] Alignment slots 216 may be formed on one or both sides of the lower frame 200 in the upper part 210 of the frame. When a replacement unit is installed on the lower frame 200, a support piece 396 formed on the hinge portion 390 of the unit container 300 can be inserted into the alignment slot 216. This has the advantage of making it easier to recognize the orientation in which the replacement unit should be assembled to the lower frame 200, thereby simplifying the assembly and inspection process, and helping to maintain the correct alignment and secure connection of the replacement unit after installation.

[0068] As described below, in one embodiment of the present invention, the powder box container 1000 can be configured such that the orientation of the replacement unit can be changed according to the user's selection. In this structure, a plurality of alignment slots 216 can be formed in the upper part 210 of the frame, and a support piece 396 can be inserted into one of the alignment slots 216. In this case, the alignment slot 216 into which the support piece 396 is not inserted can serve to indicate the position of the protruding tongue 544 of the replacement unit and provide the user with more leeway to hold the protruding tongue 544. In some embodiments of the present invention, the alignment slot 216 can be omitted, in which case the hinge portion 390 or the support piece 396 can be located above the upper part 210 of the frame.

[0069] The frame sidewall 220 corresponds to the inner wall that defines the through hole 250 on its inner side. That is, the frame sidewall 220 may extend downward from the inner side of the upper part 210 of the frame and may be formed to surround the through hole 250. The through hole 250 may be formed in the vertical direction and the unit container 300 may be inserted into its inner side. If necessary, an inwardly protruding support protrusion 222 may also be formed on the inner surface of the frame sidewall 220.

[0070] On the other hand, in the portion corresponding to the front side of the lower frame 200, components for the detachable connection between the upper and lower housings may be provided on the frame sidewall 220. For example, in the illustrated example, a support piece 226 for fixing a magnetic object (not shown) is provided on the outer surface of the frame sidewall 220. The support piece 226 allows the magnetic object (not shown) of the lower housing to be accurately aligned with the position corresponding to the magnetic object (not shown) of the upper housing.

[0071] The outer wall 240 extends downward from the outside of the upper frame 210. In the illustrated example, the outer wall 240 of the lower frame 200 corresponds to the first sliding portion, and therefore the guide rails 262, 264, the locking protrusion 270, and the stop protrusion 280 are formed on the outer wall 240. Of course, other parts of the lower frame 200 can also function as the first sliding portion. Furthermore, in some other embodiments, the sidewall 140 of the slidable base 100 may be located inside the outer wall 240 of the lower frame 200. In this case, the guide rails 262, 264, the locking protrusion 270, and the stop protrusion 280 may be provided on the inner surface of the outer wall 240, and the outer surface of the outer wall 240 may form part of the appearance of the powder box container 1000. The front portion 246 of the outer wall 240, which is located on the front side of the lower frame 200, extends downward by a shorter distance than the rest of the outer wall 240, thereby providing leeway for the support steps 126 of the sliding base 100.

[0072] Guide rails 262 and 264 may form guide grooves 260 for insertion into cross rails 162 and 163. Guide grooves 260 may interact with cross rails 162 and 163 as described above, thereby allowing the sliding base 100 to slide relative to the lower frame 200.

[0073] Guide rails 262 and 264 can extend in the front-to-back direction to form a guide groove 260 between them. Of course, the guide groove 260 can be formed by various methods and does not necessarily have to be formed between the two guide rails 262 and 264. For example... Figure 6 As shown, guide rails 262 and 264 can be configured such that guide groove 260 opens at the front. This makes it easier for cross rails 162 and 163 to be inserted when they first enter guide groove 260.

[0074] When the locking protrusion 270 and / or the stopping protrusion 280 are formed in the same sliding portion where the guide rails 262 and 264 are formed, the guide rails 262 and 264 can be formed intermittently, and the positions where the locking protrusion 270 and / or the stopping protrusion 280 are provided are temporarily omitted. This, as will be explained later, helps to ensure that space can be formed for the cantilever beams 272 and 282 for the locking protrusion 270 and the stopping protrusion 280.

[0075] The locking protrusion 270, together with the limiting protrusions 172 and 173, serves to detachably fix the slidable base 100 to the lower frame 200. As previously described, when the slidable base 100 is in a first position and / or a second position relative to the lower frame 200, the locking protrusion 270 may be configured to contact the limiting protrusions 172 and 173. In a preferred embodiment of the present invention, an inclined surface 276 (see reference) may be formed on one or both sides of the locking protrusion 270 in the front-back direction. Figure 16 and Figure 17 The inclined surface 276 prevents the resistance in the locking protrusion 270 from being too great to overcome the limiting protrusions 172 and 173.

[0076] According to one embodiment of the present invention, at least one of the locking protrusion 270 and the limiting protrusions 172, 173 may be formed on the cantilever beam 272. For example, in Figure 6 and Figure 7 In the illustrated embodiment, a locking protrusion 270 is formed on a cantilever beam 272, which extends in a front-rear direction. The front side of the cantilever beam 272 is connected to the outer wall 240 of the lower frame 200, while the rear end of the cantilever beam 272 and the upper and lower parts of the cantilever beam 272 are not connected to the outer wall 240. The locking protrusion 270 is formed at the end (i.e., the rear side) of the cantilever beam 272.

[0077] This structure allows the locking protrusion 270 to retract in a direction away from the limiting protrusions 172 and 173 (inward direction) when the sliding base 100 is pulled and the locking protrusion 270 is about to pass over the limiting protrusions 172 and 173. When the limiting protrusions 172 and 173 are formed in a similar cantilever beam, the limiting protrusions 172 and 173 can retract in a direction away from the locking protrusion 270 (outward direction). The interaction between the locking protrusion 270 and the limiting protrusions 172 and 173 will be explained in more detail later.

[0078] The stop protrusion 280 interacts with the cross rail 163, limiting the range of movement of the sliding base 100 relative to the lower frame 200. Based on the front-to-back direction, one side of the stop protrusion 280 may have an inclined surface 286 (see reference). Figure 16 and Figure 17 On the other side, a locking step 288 may be formed. Furthermore, a stop protrusion 280 may be formed on the cantilever beam 282. For example, in... Figure 6 and Figure 7 In the illustrated embodiment, a stop protrusion 280 is formed on a cantilever beam 282, which has a front-to-back shape. The front side of the cantilever beam 282 is connected to the outer wall 240 of the lower frame 200, and the upper and lower parts of the cantilever beam 282 are not connected to the outer wall 240. The stop protrusion 280 is formed at the end (i.e., the rear side) of the cantilever beam 282.

[0079] This structure allows the stop protrusion 280 to retract in a direction away from the horizontal rail 163 (inward direction) when the sliding base 100 is pulled and the horizontal rail 163 is about to pass the stop protrusion 280. The interaction between the horizontal rail 163 and the stop protrusion 280 will be explained in more detail later.

[0080] The hinge portion 290 is used to allow the upper housing to open and close relative to the lower housing. Specifically, the hinge portion 290 of the lower housing and the hinge portion 690 of the upper housing are rotatably coupled to the hinge bracket 800, thus forming a double-hinge structure that allows the upper housing to open and close relative to the lower housing. For ease of explanation, the hinge portion 290 of the lower housing is referred to as the first hinge portion, and the hinge portion 690 of the upper housing is referred to as the second hinge portion. Although the figure depicts a structure in which the hinge portion 290 of the lower housing is formed on the lower frame 200, it is also possible for the hinge portion 290 to be formed on the sliding base 100.

[0081] A first hinge portion 290 may be formed in a hinge beam 292 extending rearward from the outer wall 240 of the lower frame 200. The hinge beam 292 may be formed with a thickness less than the vertical thickness of the first hinge portion 290. A hinge hole 295 may be formed in the center of the first hinge portion 290. When the hinge hole 295 of the first hinge portion 290 is aligned with the corresponding hinge hole 895 of the hinge bracket 800, and components such as hinge pins (not shown) are inserted into the hinge holes 295 and 895, the first hinge portion 290 can be rotatably engaged with the hinge bracket 800. Ultimately, the hinge holes 295 and 895 can be considered to correspond to the rotation axis of the first hinge portion 290. For ease of explanation, the rotation axis of the first hinge portion 290 is referred to as the first rotation axis, and the rotation axis of the second hinge portion 690 is referred to as the second hinge axis.

[0082] Reference Figure 18 The first hinge portion 290 may include an arc portion 294, a flat portion 296, and a curved portion 298.

[0083] The arc portion 294 is a portion having an arc-shaped cross-section. The arc portion 294 can be connected along an arc from the lower part of the hinge beam 292 to a predetermined position, preferably at a height corresponding to the center of the hinge hole 295 (first hinge axis). The center of the arc corresponding to the cross-section of the arc portion 294 can correspond to the center of the hinge hole 295 (first hinge axis). The arc portion 294 allows the first hinge portion 290 to rotate relative to the shielding portion 850 of the hinge support 800 within a predetermined range.

[0084] The flat portion 296 can connect from the arc portion 294 along the flat surface to a predetermined height above it. The flat portion 296 contacts the shielding portion 850 of the hinge bracket 800, thereby preventing the first hinge portion 290 from rotating relative to the shielding portion 850 of the hinge bracket 800 within a predetermined range.

[0085] The curved portion 298 can extend from the upper part of the flat portion 296 in a curved shape to the upper part of the hinge beam 292. The curved portion 298 can form a certain amount of slack space above the flat portion 296 to prevent the first hinge portion 290 and the second hinge portion 690 from hindering each other's rotation.

[0086] Refer again Figure 7As needed, one of the first hinge portion 290 and the second hinge portion 690 may include a boss 299. The boss 299 may protrude around the hinge hole 295 in a direction toward the bracket body 810 of the hinge bracket 800. When the hinge bracket 800 is engaged with the hinge portion 290, the boss 299 may be inserted into the guide groove 899 of the bracket body 810. With the formation of the boss 299, it becomes easier to distinguish which hinge portion 290, 690 should engage with each hinge hole 895 formed on the bracket body 810, thereby making the assembly of the powder box container 1000 easier.

[0087] The unit container 300 is part that forms a receiving space 350 for actually containing contents such as cosmetics (not shown). As previously mentioned, the unit container 300, together with the retaining ring 400 and the unit cap 500, can form a replacement unit. Figure 8 and Figure 9 This is a perspective view of the unit container 300 of a powder box container 1000 according to an embodiment of the present invention, viewed from above and below. Figure 8 and Figure 9 As shown, the unit container 300 may include a bottom 310, an inner wall 320, an outer wall 340, fixing protrusions 352 and 354, and a hinge portion 390. For reference, the hinge portion 390 is formed on the side of the unit container 300.

[0088] The bottom 310 may form the lower part of the unit container 300. The bottom 310 may define the receiving space 350 together with the inner wall 320 of the container. That is, the receiving space 350 may be formed above the bottom 310 and inside the inner wall 320 of the container.

[0089] The inner wall 320 of the container may extend upward from the bottom 310 and may form a receiving space 350 on the inside for receiving contents (not shown). The length of the inner wall 320 of the container in the vertical direction may be determined by taking into account the amount of contents to be provided to the receiving space 350.

[0090] The inner wall 320 of the container may be formed with protrusions and / or grooves for engaging with the retaining ring 400. For example, in Figure 3 and Figure 4 In the structure shown, a mating groove can be formed on the outer surface of the inner wall 320 of the container, and a mating protrusion configured to be inserted into the mating groove is formed on the mating edge 450 of the retaining ring 400.

[0091] The contents contained in the receiving space 350 of the unit container 300 can be provided in various forms, such as solidified agglomerated powders, creams, gels, liquids, etc. When the contents are not solid, they can be disposed in the receiving space 350 in a state of being immersed in an immersion part (not shown). The immersion part (not shown) is, for example, made of a porous material such as a sponge, and its internal pores can hold contents such as creams and liquids.

[0092] The outer wall 340 of the container can be formed at a predetermined distance from the inner wall 320 of the container, thus forming a connecting space between the inner wall 320 and the outer wall 340. Although the outer wall 340 is depicted in the illustrated example as extending upward from the bridging portion 330 protruding outward from the inner wall 320, the outer wall 340 can also be formed to extend upward from the bottom 310. However, since the bridging portion 330 connecting the outer wall 340 is located at a predetermined distance from the bottom 310 and the fixing protrusions 352, 354 formed at the same height thereon, a gap can be formed between the bridging portion 330 and the fixing protrusions 352, 354. The advantage of this structure is that when the slidable base 100 is in the first position, a portion of the locking protrusions 152, 154 can be inserted between the fixing protrusions 352, 354 and the bridging portion 330.

[0093] As needed, protrusions and / or grooves for engaging with the retaining ring 400 may also be formed on the outer wall 340 of the container. For example, although not shown in the figure, engaging protrusions may be formed on the inner surface of the outer wall 340 of the container, and engaging grooves may be formed on the outer surface of the engaging edge 450 of the retaining ring 400. When the retaining ring 400 is engaged with the unit container 300, the engaging protrusions of the outer wall 340 of the container can be inserted into the engaging grooves of the retaining ring 400.

[0094] Furthermore, a frame 346 may be formed on the upper part of the outer wall 340 of the container, as needed. The frame 346 may protrude outward from the upper part of the outer wall 340 of the container, and its outer portion may form a gentle curve. As the frame 346 protrudes outward from the outer wall 340 of the container, a step may be formed below the frame 346, and when the unit container 300 is inserted into the through hole 250 of the lower frame 200, the step below the frame 346 may be placed on the upper part 210 of the frame.

[0095] Protrusions and / or grooves for engaging with the unit cover 500 may be formed on the outer wall 340 of the container. For example, in Figure 3 and Figure 4In the structure shown, a sealing groove 356 is formed in the portion of the outer wall 340 of the container that protrudes upward from the upper part 210 of the lower frame 200 (the inner part of the frame 346). When the unit cover 500 is closed above the unit container 300 (in the closed position), the sealing protrusion 556 of the sealing ring 550 can be inserted into the sealing groove 356 of the outer wall 340 of the container, and the edge 520 of the unit cover 500 can be placed on the frame 346.

[0096] The fixing protrusions 352 and 354 engage with the locking protrusions 152 and 154 to fix or loosen the unit container 300 relative to the lower frame 200. The fixing protrusions 352 and 354 can protrude horizontally at positions corresponding to the locking protrusions 152 and 154. The fixing protrusions 352 and 354 can be formed at various locations on the unit container 300, but since the fixing protrusions 352 and 354 are fixed when the locking protrusions 152 and 154 are above them, forming them at a lower height may be advantageous. (See reference...) Figure 9 The fixed protrusions 352 and 354 are formed at the lowest position of the unit container 300, and the bottom surface of the fixed protrusions 352 and 354 is continuous with the bottom surface of the bottom 310.

[0097] Furthermore, for structural stability, the fixing protrusions 352 and 354 can be formed at multiple locations within the unit container 300, preferably at three or more locations. Figure 9 In the structure shown, the front fixing protrusion 352 protrudes forward from the outer surface of the inner wall 320 of the unit container 300 on the front side, and the side fixing protrusions 354 protrude outward from the outer surface of the inner wall 320 on the left and right sides of the unit container 300. In the structure shown, the fixing protrusions 354 on both sides are also connected to the rear side of the unit container 300 to form a rear fixing protrusion 353, but... Figure 9 In the embodiment shown, the rear fixing protrusion 353 formed on the rear side of the unit container 300 may also be omitted.

[0098] Conversely, in one embodiment of this invention... Figure 9The side fixing protrusion 354 of the fixing protrusions 352, 353, and 354 shown may also be omitted. That is, the unit container 300 may only include the front fixing protrusion 352 and the rear fixing protrusion 353. In this case, the rear fixing protrusion 353 may be configured to engage with a separate protrusion provided on the lower frame 200 or be inserted into a separate slot, rather than interacting with the locking protrusions 152 and 154 of the sliding base 100. For example, as the unit container 300 is mounted on the lower frame 200, the rear fixing protrusion 353 may be inserted under a separate protrusion (not shown), and the front fixing protrusion 352 may be fixed to or not fixed to the locking protrusion 152 depending on the position of the sliding base 100. Of course, in this case, the protrusion (not shown) that fixes the rear fixing protrusion 353 may protrude a shorter length to avoid seriously hindering the insertion and installation of the unit container 300, and the portion in contact with the rear fixing protrusion 353 may also have an inclined surface and / or a curved surface.

[0099] on the other hand, Figure 10 This is a perspective view of the unit container 300 of the powder box container 1000 according to another embodiment of the present invention, viewed from below.

[0100] like Figure 10 As shown, in one embodiment of this utility model, the fixing protrusions of the unit container 300 may include a front fixing protrusion 352, a rear fixing protrusion 353, and side fixing protrusions 354 and 355. The side fixing protrusions 354 and 355 may include a first side fixing protrusion 354 and a second side fixing protrusion 355 formed at a predetermined distance. The first side fixing protrusion 354 and the second side fixing protrusion 355 are both formed on the left and right sides of the unit container 300. The first side fixing protrusion 354 may be formed near the rear side of the unit container 300, and the second side fixing protrusion 355 may be formed near the front side of the unit container 300. However, as will be described later, in this case, the unit container 300 may not have a front-rear distinction.

[0101] According to one embodiment of the present invention, the unit container 300 may be configured such that the fixed protrusions on the front and rear sides are symmetrical. This symmetry can be linear symmetry with respect to a reference line extending in the left-right direction in the front-rear direction, or it can be rotational symmetry about the center of the unit container 300.

[0102] An example of a symmetrical structure of the fixed protrusions in the unit container 300 is depicted in Figure 10 .exist Figure 10In the example shown, the front fixing protrusion 352 has a shape corresponding to the rear fixing protrusion 353, and the second side fixing protrusion 355 has a shape corresponding to the first side fixing protrusion 354, so that the fixing protrusions of the unit container 300 are linearly and rotationally symmetrical. When the fixing protrusions are symmetrical in this way, it has the advantage that the orientation of the unit container 300 can be selected when the unit container 300 is mounted on the lower frame 200.

[0103] For example, from the perspective of a user using the toner cartridge container 1000, when the unit container 300 is in such a state... Figures 20(a) to 20(d) When the hinge portion 390 is mounted on the lower frame 200 with the user's left side facing it, the front fixing protrusion 352 interacts with the front locking protrusion 152 as the sliding base 100 moves, while the first side fixing protrusion 354 interacts with the side locking protrusion 154. If the user finds it more convenient to have the hinge portion 390 facing the user's right side due to left-handedness or other reasons, the user can change the orientation of the unit container 300 and mount it on the lower frame 200. In this case, the powder container 1000 still functions, and as the sliding base 100 moves, the rear fixing protrusion 353 interacts with the front locking protrusion 152, and the second side fixing protrusion 355 interacts with the side locking protrusion 154.

[0104] That is, with the fixing protrusions formed symmetrically, the front fixing protrusion 352 can be interchanged with the rear fixing protrusion 353, and the first side fixing protrusion 354 can be interchanged with the second side fixing protrusion 355. Ultimately, it becomes possible to install the unit container 300 and the replacement unit with the rear fixing protrusion 353 facing the front.

[0105] about Figures 8 to 10 The interaction between the fixed protrusions 352-355 and the locking protrusions 152 and 154 shown will be explained in more detail later.

[0106] Reference Figures 8 to 10A hinge portion 390 is formed on one side of the unit container 300 and can be used to rotatably engage the unit cover 500. In the illustrated example, the unit container 300 has a pair of hinge portions 390, and the hinge portion 590 of the unit cover 500 is inserted between the pair of hinge portions 390 of the unit container 300 for engagement. A support piece 396 is provided below the pair of hinge portions 390 to reinforce the hinge portions 390. The support piece 396 can be inserted into an alignment slot 216 formed in the upper frame portion 210 of the lower frame 200. As mentioned above, in a structure where the orientation of the hinge portions 390, 590 in the replacement unit can be selected according to the user's preferred orientation, multiple alignment slots 216 can be formed in the upper frame portion 210, and the support piece 396 can be inserted into one of the alignment slots 216. Of course, the support piece 396 can also be omitted, or the support piece 396 can be placed in the upper frame portion 210 instead of being inserted into the alignment slot 216.

[0107] Hinge holes 395 and 595 are formed on the hinge portions 390 and 590 of the unit container 300 and the unit cover 500, respectively. When the hinge portion 390 of the unit container 300 and the hinge portion 590 of the unit cover 500 are aligned with each other, and a hinge pin (not shown) is inserted into the hinge holes 395 and 595 of the hinge portions 390 and 590, the unit cover 500 can rotate relative to the unit container 300 about the hinge pin (not shown). When the user wants to use the contents in the containing space 350, the unit cover 500 can be rotated and lifted. In order to distinguish it from the hinge portion 290 of the lower housing and the hinge portion 690 of the upper housing, the hinge portion 390 of the unit container 300 and the hinge portion 590 of the unit cover 500 are respectively referred to as the third hinge portion 390 and the fourth hinge portion 590.

[0108] As shown in the example, when the first hinge portion 290 and the second hinge portion 690 are located at the rear of the powder container 1000, the third hinge portion 390 and the fourth hinge portion 590 can be configured to face either the left or the right. For example, the third hinge portion 390 and the fourth hinge portion 590 can be formed at a 90-degree angle with reference to the first hinge portion 290 and the second hinge portion 690. However, this invention is not limited by the position of the third hinge portion 390 and the fourth hinge portion 590.

[0109] As previously described, the replacement unit can be configured to attach to the lower frame 200 such that the third hinge portion 390 and the fourth hinge portion 590 can be selectively positioned at either a 90-degree angle to the left or a 90-degree angle to the right, with reference to the first hinge portion 290 and the second hinge portion 690. When the third hinge portion 390 and the fourth hinge portion 590 are positioned at a 90-degree angle to the left with reference to the first hinge portion 290 and the second hinge portion 690, the unit cover 500 rotates to the left around the third hinge portion 390 and the fourth hinge portion 590, so that when in the open state, it does not obstruct the upper housing (upper frame 600 and cover 700) or hinder the user's right hand from accessing the receiving space 350. Similarly, when the third hinge portion 390 and the fourth hinge portion 590 are positioned at a 90-degree angle to the right with reference to the first hinge portion 290 and the second hinge portion 690, the unit cover 500 rotates to the right with the third hinge portion 390 and the fourth hinge portion 590 as the center, so that when it is in the open state, it will not obstruct the upper shell, nor will it hinder the user's left hand from accessing the receiving space 350.

[0110] The retaining ring 400 can be attached to the upper part of the unit container 300 to prevent the contents (not shown) from leaving the receiving space 350. Figure 2 As shown in Figure 4, the retaining ring 400 may include a supporting flange 410 and a mating flange 450.

[0111] The support flange 410 may be integrally flat and may be located on the upper part of the inner wall 320 of the unit container 300. The support flange 410 may protrude inward from the upper end of the mating edge 450, while the mating edge 450 may extend downward from the outer edge of the support flange 410. Therefore, the support flange 410 and the mating edge 450 cause the retaining ring 400 to... Figure 3 and Figure 4 The figure shows A cross-section shaped like a character.

[0112] The support flange 410 may have a through hole formed on its inner side. When the retaining ring 400 is attached to the unit container 300, the support flange 410 may protrude inward from the upper end of the inner wall 320 of the container, and the through hole may be located above the receiving space 350.

[0113] The mating edge 450 can extend downward from the support flange 410, and when the retaining ring 400 is mated to the unit container 300, the mating edge 450 can be in close contact with the outer surface of the container inner wall 320.

[0114] Grooves and / or protrusions for engaging the retaining ring 400 with the unit container 300 may be formed on the mating edge 450. For example, in Figure 3 and Figure 4In the structure shown, a connecting protrusion is formed on the inner surface of the connecting edge 450. When the retaining ring 400 is connected to the unit container 300, the connecting protrusion of the connecting edge 450 is inserted into the connecting groove formed on the outer peripheral surface of the inner wall 320 of the container.

[0115] In one embodiment of this utility model, protrusions and / or grooves for engaging the retaining ring 400 with the unit container 300 may also be formed on the supporting flange 410. Figure 3 and Figure 4 In the example shown, a downwardly protruding engagement protrusion 430 is formed on the lower surface of the support flange 410. When the retaining ring 400 is engaged with the unit container 300, the upper end of the inner wall 320 of the container can be inserted between the engagement flange 450 and the engagement protrusion 430 of the support flange 410.

[0116] The unit cover 500, as part of the replacement unit, is the portion that is hinged to the unit container 300 and covers the upper part of the receiving space 350. Figure 11 This is a perspective view illustrating the unit cover 500 of a powder box container 1000 according to an embodiment of the present invention. Figures 2 to 4 and Figure 11 As shown, the unit cover 500 may include a cover portion 510, an edge portion 540, a sealing ring 550, and a hinge portion 590.

[0117] The cover portion 510, as the main part of the unit cover 500, corresponds to the portion covering the unit container 300. The cover portion 510 may have a flat bottom surface, which, in a preferred embodiment of the present invention, may be configured to completely cover the through hole of the retaining ring 400. When the unit cover 500 is closed, the flat bottom surface of the cover portion 510 may rest on the flat top surface of the support flange 410 of the retaining ring 400.

[0118] As shown in the example, the edge of the cover 510 can be bent upwards. Thus, on the one hand, a space for placing tools such as powder puffs is formed in the center of the upper part of the cover 510, and on the other hand, a mounting groove for inserting the sealing ring 550 is formed at the lower edge of the cover 510.

[0119] The edge portion 540 may extend downward from the edge of the cover portion 510. As the edge portion 540 extends obliquely downward from the upwardly curved portion of the cover portion 510, a mounting groove for inserting the sealing ring 550 may be formed on the inner side of the edge portion 540.

[0120] A protruding tongue 544 may be formed on the opposite side of the portion in the unit cover 500 where the hinge portion 590 is formed. The protruding tongue 544 functions as a handle, allowing the user to easily open the unit cover 500. The protruding tongue 544 may be formed on the cover portion 510 and / or the edge portion 540.

[0121] The sealing ring 550 can be inserted into the mounting groove formed by the cover portion 510 and the edge portion 520, thereby improving the sealing performance of the unit container 300 when the unit cover 500 is closed. The sealing ring 550 may include a mounting portion 552 having a shape corresponding to the mounting groove (see reference). Figure 3 A sealing protrusion 556 extending downward from the mounting portion 552. When the unit cover 500 covers the through hole of the retaining ring 400, the sealing protrusion 556 can be... Figure 3 and Figure 4 The sealing ring 550 is attached to the outer wall 340 of the container 300 and can be partially inserted into the sealing groove 356 formed in the outer wall 340. On the other hand, the mounting portion 552 of the sealing ring 550 can also be partially attached to the outer wall 340. The mounting portion 552 can be pressed to fit against the upper end of the outer wall 340, for example.

[0122] A hinge portion 590 (fourth hinge portion) may be formed in the unit cover 500, and a hinge hole 595 may be formed on the hinge portion 590 for a hinge pin (not shown) to pass through. The unit cover 500 may be configured such that the hinge hole 595 of the hinge portion 590 on the unit cover side aligns with the hinge hole 395 of the hinge portion 390 on the unit container side. When the hinge pin (not shown) is inserted through the hinge holes 395, 595 of the third hinge portion 390 and the fourth hinge portion 590, the unit cover 500 may be rotatably coupled to the unit container 300 around the hinge pin (not shown). Of course, the third hinge portion 390 and the fourth hinge portion 590 may be implemented in various structures, including structures that do not utilize a hinge pin.

[0123] The upper frame 600 can be combined with the cover 700 to form the upper shell. Figure 12 and Figure 13 These are perspective views of the upper frame 600 of a powder box container 1000 according to an embodiment of the present invention, viewed from above and below, respectively. Figure 12 and Figure 13 As shown, the upper frame 600 may include a frame platform 620 and a second hinge portion 690.

[0124] The frame platform 620 constitutes the main part of the upper frame 600 and bears the self-load of the upper shell and the external forces applied to the upper shell. In the illustrated example, the frame platform 620 has a through hole 650 formed on its inner side, configured to allow the mirror 715 provided on the cover 700 to be exposed through the through hole 650. Of course, it is also possible that the mirror 715 and other components are provided on the frame platform 620, instead of the frame platform 620 having a through hole 650.

[0125] Grooves and / or protrusions may be formed on the frame platform 620 for the engagement of the upper frame 600 and the cover 700. For example, in Figures 12 to 14In the structure shown, a connecting protrusion 626 is formed on the outer surface of the frame platform 620. When the cover 700 is connected to the upper frame 600, the connecting protrusion 626 of the frame platform 620 is inserted into the connecting groove 746 formed on the cover side wall 740 of the cover 700.

[0126] Depending on the needs, the front side of the frame platform 620 may be provided with components for the detachable connection of the upper and lower housings. For example, in the illustrated example, the front side of the frame platform 620 has a mounting groove 662 for placing a magnetic object (not shown). When the cover 700 is attached to the upper frame 600, the magnetic object can be arranged in the space created by the mounting groove 622. Furthermore, the front side of the frame platform 620 may have an insertion groove 624 that opens upwards. When the cover 700 is attached to the upper frame 600, the support piece 744 of the cover 700 can be inserted into the insertion groove 624. This structure serves to fix the magnetic object (not shown) in a relatively precise position.

[0127] The hinge portion 690 can be used to allow the upper housing to open and close relative to the lower housing. As previously described, the first hinge portion 290 of the lower housing and the second hinge portion 690 of the upper housing can be rotatably coupled to the hinge bracket 800, respectively.

[0128] The second hinge portion 690 may be formed in a hinge beam 692 extending rearward from the frame platform 620 of the upper frame 600. The thickness of the hinge beam 692 may be less than the thickness of the second hinge portion 690 in the vertical direction. As needed, the thickness of the hinge beam 692 of the second hinge portion 690 may be less than the thickness of the hinge beam 292 of the first hinge portion 290.

[0129] A hinge hole 695 may be formed in the center of the second hinge portion 690. When the hinge hole 695 of the second hinge portion 690 is aligned with the corresponding hinge hole 895 of the hinge bracket 800, and components such as a hinge pin (not shown) are inserted into the hinge holes 695 and 895, the second hinge portion 690 can be rotatably engaged with the hinge bracket 800. Ultimately, the hinge holes 695 and 895 can be considered to correspond to the rotation axis of the second hinge portion 690.

[0130] Similar to the first hinge portion 290, the second hinge portion 690 may include an arcuate portion 694, a flat portion 696, and a curved portion 698. The arcuate portion 694, having an arcuate cross-section, can be connected along an arc from the lower part of the hinge beam 692 to a predetermined position, preferably at a height corresponding to the center of the hinge hole 695 (the second hinge axis). The center of the arc corresponding to the cross-section of the arcuate portion 694 may correspond to the center of the hinge hole 695 (the second hinge axis). The arcuate portion 694 allows the second hinge portion 690 to rotate relative to the shielding portion 850 of the hinge support 800 within a predetermined range.

[0131] The flat portion 696 can connect to the arc portion 694 along the flat surface to a predetermined height above it. The flat portion 696 contacts the shielding portion 850 of the hinge bracket 800, thereby preventing the second hinge portion 690 from rotating relative to the shielding portion 850 of the hinge bracket 800 within a predetermined range. The curved portion 698 can connect to the upper part of the flat portion 696 in a curved shape and extend to the upper part of the hinge beam 692. The curved portion 698 can form a certain amount of slack space above the flat portion 696 to prevent the first hinge portion 290 and the second hinge portion 690 from hindering each other's rotation.

[0132] The cover 700 can be combined with the upper frame 600 to form the upper shell. The cover 700 can form the exterior of the upper shell and can constitute a major part of the overall appearance of the powder box container 1000. Figure 14 This is a perspective view illustrating the lid 700 of a powder box container 1000 according to an exemplary embodiment of the present invention. Figure 14 As shown, the cover 700 may include a cover plate 710 and a cover sidewall 740.

[0133] Cover plate 710, as the main part of cover 700, corresponds to the portion covering the replacement unit. Cover plate 710 may have a flat shape overall, and a mirror 715 may be mounted on its bottom surface. If necessary, a separate decorative panel 712 may be mounted on top of cover plate 710.

[0134] The cover sidewall 740 may project downward from the cover plate 710, forming an inner space for accommodating a replacement unit and tools such as a powder puff disposed above it. Protrusions and / or grooves may be formed on the cover sidewall 740 for engagement with the upper frame 600. For example, in Figures 12 to 14 In the structure shown, a mating groove 746 is formed on the inner surface of the cover sidewall 740. When the cover 700 is mated to the upper frame 600, the mating protrusion 626 of the frame platform 620 is inserted into the mating groove 746 of the cover sidewall 740.

[0135] As needed, the front side of the cover sidewall 740 may be provided with components for detachable connection between the upper and lower housings. For example, in the illustrated example, a support step 742 is formed on the front side of the cover sidewall 740, and support plates 744 extend further downward on both sides thereon. When the cover 700 is attached to the upper frame 600, a magnetic object (not shown) can be disposed below the support step 742 within a mounting groove 622. The support plate 744 can be inserted into the insertion groove 624 of the upper frame 600, and the magnetic object (not shown) can be fixed therebetween.

[0136] A space for the hinge bracket 800 may be formed on the rear side of the cover sidewall 740. This space may be sized to allow the hinge bracket 800 to rotate within a predetermined range and to allow the cover plate 710 to contact the hinge bracket 800 after reaching a specific angle.

[0137] The hinge bracket 800 can be combined with the hinge portions 290 and 690 of the upper and lower housings to form a double hinge. Figure 15 This is a perspective view illustrating the hinge bracket 800 of a powder box container 1000 according to an embodiment of the present invention. Figure 15 As shown, the hinge bracket 800 may include a bracket body 810 and a shielding part 850.

[0138] The bracket body 810 corresponds to the portion of the hinge bracket 800 that is actually engaged with the hinge portions 290 and 690 of the upper and lower housings. In the illustrated example, the lower frame 200 includes a pair of first hinge portions 290, and the upper frame 600 includes a pair of second hinge portions 690. The bracket body 810 is inserted between the pair of first hinge portions 290 and second hinge portions 690 for engagement. For this purpose, the bracket body 810 may extend relatively long in the left-right direction, and hinge holes 895 may be formed on its two end portions. As mentioned above, guide grooves 899 may be formed together in one or more of the hinge holes 895.

[0139] A flat surface 812 with a flat shape can be formed on the inner (front) surface of the support body 810. A flat surface 816 with a flat shape and an arcuate surface 814 with an arcuate cross-section formed on the upper and lower parts of the support body 810 can be formed on the outer (rear) surface of the support body 810. In the powder box container 1000 of one embodiment of the present invention, the flat surface 816 on the outer side of the support body 810 is always exposed to the outside, regardless of the configuration of the upper shell. Furthermore, in the 180-degree unfolded position where the upper shell is 180 degrees relative to the lower shell, the flat surface 812 on the inner side of the support body 810 is exposed between the mirror 715 and the replacement unit. Due to this structure, trademarks or patterns can be printed or engraved on the flat surfaces 812 and 816 of the support body 810, thereby improving the utilization as a design element.

[0140] The shielding portion 850 is the portion that shields the outer (rear) side of the first hinge portion 290 and the second hinge portion 690. The shielding portion 850 may extend in such a way that end portions 852 are formed at the upper and lower parts, and may be formed on the outer (rear) side of the hinge hole 895 of the bracket body 810.

[0141] An arcuate surface 840 and a flat surface 860 may be formed on the inner (front) surface of the shielding portion 850. The arcuate surface 840 corresponds to a surface having an arcuate cross-section, and the flat surface 860 corresponds to a surface having a flat shape. The arc formed by the cross-section of the arcuate surface 840 may have a radius of curvature corresponding to the arc formed by the cross-sections of the arcuate portions 294 and 694 of the first hinge portion 290 and the second hinge portion 690.

[0142] A flat surface 856 with a flat shape and an arc surface 854 with an arc-shaped cross section can be formed on the outer (rear) surface of the shielding part 850. The arc surface 854 and the flat surface 856 on the outer side of the shielding part 850 can be naturally connected to the arc surface 814 and the flat surface 816 on the outer side of the support body 810.

[0143] Refer to Figure 1 to... Figure 19 The operation of the sliding base 100 in the powder box container 1000 of one embodiment of the present invention will be described in more detail. Figure 16 and Figure 17 This is a conceptual diagram illustrating, by way of example, the states of the first sliding portion and the second sliding portion when the slidable base 100 in the powder box container 1000 is in the first position and the second position, respectively.

[0144] After fabricating the various components of the powder box container 1000, the sliding base 100 and the lower frame 200 can be combined to form the lower shell, the unit container 300, the retaining ring 400, and the unit cover 500 can be combined to form the replacement unit, and the upper frame 600 and the cover 700 can be combined to form the upper shell. The lower frame 200 and the upper frame 600 can be rotatably connected to the hinge bracket 800.

[0145] The sliding base 100 is initially attached to the lower frame 200 when the unit container 300 of the replacement unit is inserted into the through hole 250 of the lower frame 200 for installation. As mentioned above, the user can install the replacement unit by orienting the third hinge portion 390 and the fourth hinge portion 590 in the desired direction.

[0146] When the sliding base 100 is initially attached to the lower frame 200, the rear cross rail 163 can first be inserted into the guide groove 260 on the front side of the lower frame 200. As mentioned above, the guide rails 262 and 264 forming the guide groove 260 have a shape that opens towards the front side of the guide groove 260, allowing the cross rail 163 to enter easily.

[0147] The horizontal rail 163, inserted into the guide groove 260, can reach the locking protrusion 270. When the locking protrusion 270 is not formed on the cantilever beam 272, it may obstruct the entry of the horizontal rail 163. However, since the locking protrusion 270 is formed on the cantilever beam 272, it retracts in a direction away from the horizontal rail 163 (inward direction) due to the elastic deformation of the cantilever beam 272, thus allowing the horizontal rail 163 to enter. Because the locking protrusion 270 has an inclined surface 276, the locking protrusion 270 can naturally retract when the horizontal rail 163 contacts it. In the illustrated example, at the point when the horizontal rail 163 passes the locking protrusion 270, the limiting protrusions 172 and 173 can also be inserted into the front side of the guide groove 260.

[0148] The cross rail 163, having passed the locking protrusion 270, can then reach the stop protrusion 280. Similarly, when the stop protrusion 280 is not formed on the cantilever beam 282, it may obstruct the entry of the cross rail 163. However, since the stop protrusion 280 is formed on the cantilever beam 282, it retracts in a direction away from the cross rail 163 (inward direction) due to the elastic deformation of the cantilever beam 282, thus allowing the cross rail 163 to enter. Because the stop protrusion 280 has an inclined surface 286 formed on it, the stop protrusion 280 can naturally retract when the cross rail 163 contacts it.

[0149] After the horizontal rail 163 passes the stop protrusion 280, the stop protrusion 280 will return to its original position due to the elastic restoring force of the cantilever beam 282. At the point when the horizontal rail 163 passes the stop protrusion 280, the locking step 288 of the stop protrusion 280 faces the horizontal rail 163. Since the locking step 288 does not have an inclined surface, it will not move backward, but will only restrict the movement of the horizontal rail 163. Ultimately, the movement range of the horizontal rail 163 is limited to the area between the rear end of the guide groove 260 and the locking step 288 of the stop protrusion 280, and correspondingly, the movement range of the sliding base 100 is also limited to the range corresponding to this area.

[0150] Before the rear horizontal rail 163 reaches the rear end of the guide groove 260, the front horizontal rail 162 can also be inserted into the front of the guide groove 260. Since the front and rear horizontal rails 162 and 163 are inserted into the guide groove 260 and supported by the guide rails 262 and 264, the sliding base 100 can maintain a horizontal alignment with the lower frame 200.

[0151] As the rear transverse rail 163 approaches the rear end of the guide groove 260, the limiting protrusions 172 and 173 entering the guide groove 260 reach the locking protrusion 270. The rear limiting protrusion 173 presses against the inclined surface 276 of the locking protrusion 270. Through the elastic deformation of the cantilever beam 272, the locking protrusion 270 retracts in a direction away from the limiting protrusion 173 (inward direction), thereby allowing the limiting protrusion 173 to enter. Simultaneously as the limiting protrusion 173 passes the locking protrusion 270, the rear transverse rail 163 reaches the rear end of the guide groove 260. In the illustrated structure, the position of the sliding base 100 at this time corresponds to the first position.

[0152] Figure 16 This is a conceptual diagram illustrating the state of the first sliding portion and the second sliding portion when the slidable base 100 in the powder box container 1000 of an embodiment of the present invention is in a first position. Figure 16 The image shows both the first sliding part (the outer wall 240 of the lower frame 200) and the second sliding part (the side wall 140 of the sliding base 100).

[0153] When the sliding base 100 is in the first position, the rear transverse rail 163 is located at the rear end of the guide groove 260, the front transverse rail 162 is located at the front of the guide groove 260, and the locking protrusion 270 is located at the front of the limiting protrusion 173. When a pair of limiting protrusions 172 and 173 are provided, the locking protrusion 270 can be located in the limiting groove 175 between the limiting protrusions 172 and 173. The first position of the sliding base 100 can correspond to the position where the front wall 120 of the sliding base 100 is moved inward to the maximum extent, and the front surface of the front wall 120 can be located on the same plane as the front surface of the cover 700.

[0154] When the sliding base 100 is in the first position, the locking protrusions 152 and 154 of the sliding base 100 are located above the fixing protrusions 352 and 354 of the unit container 300, preventing the unit container 300 from moving vertically. That is, when the sliding base 100 is in the first position, the fixing protrusions 352 and 354 are engaged with the locking protrusions 152 and 154, resulting in the unit container 300 and the replacement unit being fixed together on the lower frame 200.

[0155] Furthermore, when the sliding base 100 is in the first position, such as Figure 17 As shown, the limiting protrusion 173 contacts the locking protrusion 270 to apply resistance, so the sliding base 100 will not disengage from this position unless an external force is applied. In particular, when the upper housing covers the lower housing, it is difficult to apply a force to separate the sliding base 100 from the lower frame 200 because most of the exposed portion of the lower housing is part of the sliding base 100. That is, in order to apply a force to separate the sliding base 100 from the lower frame 200, forces should be applied to both the sliding base 100 and the lower frame 200, but when the sliding base 100 is in the first position, almost all of the lower frame 200 is blocked by the sliding base 100, so the possibility of the sliding base 100 separating due to accidental force is extremely low.

[0156] When the contents of the replacement unit are exhausted or other replacement units need to be separated, the user can pull the sliding base 100 to the second position to separate the replacement unit. The limiting protrusion 173 contacts the locking protrusion 270 and applies resistance, but because the locking protrusion 270 and the limiting protrusion 173 form inclined surfaces 276 on the portions facing each other, when sufficient external force is applied, the limiting protrusion 173 again causes the locking protrusion 270 to retract inward, allowing the sliding base 100 to move.

[0157] As previously mentioned, when the upper housing covers the lower housing, it is difficult to pull the sliding base 100 alone. However, as shown in FIG20(b), when the upper housing is fully extended, the inner flat surface 812 of the support body 810 of the hinge bracket 800 faces upward and the outer flat surface 816 faces downward, and the hinge bracket 800 is firmly fixed to the lower frame 200, so the user can easily apply force to the sliding base 100 and the lower frame 200.

[0158] When the user pulls the sliding base 100 with sufficient force, the limiting protrusion 173 passes the locking protrusion 270, and the sliding base 100 slides forward. The rear cross rail 163 reaches the stop protrusion 280 again, and at this time, the locking step 288 of the stop protrusion 280 faces the cross rail 163, preventing the stop protrusion 280 from retracting inward. Figure 17 As shown, when the horizontal rail 163 contacts the stop protrusion 280, the movement of the slidable base 100 stops. That is, the stop protrusion 280 can stop the slidable base 100 in the second position by restricting the horizontal rail 163.

[0159] When the sliding base 100 is in the second position, the locking protrusions 152 and 154 of the sliding base 100 are not located above the fixing protrusions 352 and 354 of the unit container 300, and the unit container 300 can move upward after the lock is released. The user can separate the replacement unit as shown in FIG20(d), and can install the replacement unit in the through hole 250 of the lower frame 200 when the receiving space 350 is filled with contents as needed.

[0160] The following reference Figures 1(a) to 19 The operation of the double-hinge structure of the powder box container 1000 according to one embodiment of the present invention will be described in more detail. Figure 18 and Figure 19 This is a conceptual diagram exemplarily showing the states of the first hinge portion 290, the second hinge portion 690, and the hinge support 800 when the upper frame 600 in the powder cartridge container 1000 is in a closed position and a 180-degree open position, respectively. For reference, Figure 18 and Figure 19 The sliding base 100 and cover 700 are omitted from the text.

[0161] In one embodiment of this utility model, when the upper shell is in a closed position covering the lower shell, the powder box container 1000 can be in the state shown in Figures 1(a) and 1(b), and the first hinge portion 290 and the second hinge portion 690 can be as follows: Figure 18As shown, they overlap in the vertical direction. Here, the arcuate portions 294 and 694 of the first hinge portion 290 and the second hinge portion 690 can be adjacent to the arcuate surface 840 inside the shielding portion 850, and the flat portions 296 and 696 of the first hinge portion 290 and the second hinge portion 690 can be adjacent to the flat surface 860 inside the shielding portion 850.

[0162] According to one embodiment of the present invention, the first frictional force resisting the relative rotation of the first hinge portion 290 relative to the hinge support 800 can be less than the second frictional force resisting the relative rotation of the second hinge portion 690 relative to the hinge support 800. The frictional force on the hinge portions 290 and 690 of the hinge support 800 can be adjusted, for example, by the material, surface roughness, and diameter of the hinge pins (not shown) inserted into the respective hinge holes 295 and 695.

[0163] When the user wants to use the powder container 1000, the upper shell can be lifted. As the second hinge portion 690 rotates relative to the hinge bracket 800, the hinge bracket 800 rotates relative to the first hinge portion 290, allowing the upper shell to open. When the frictional force (first frictional force) of the first hinge portion 290 is less than the frictional force (second frictional force) of the second hinge portion 690, the upper shell will not rotate relative to the hinge bracket 800, and the hinge bracket 800 can rotate relative to the lower shell first.

[0164] Although the first hinge portion 290 includes a flat portion 296, when the hinge support 800 rotates in the open direction, the hinge support 800 moves in a direction away from the flat portion 296, and the arcuate surface 840 of the hinge support 800 moves along the arcuate portion 294 of the first hinge portion 290, thus allowing rotation. Furthermore, since the first hinge portion 290 and the second hinge portion 690 each include bent portions 298 and 698, respectively, the first hinge portion 290 and the second hinge portion 690 do not obstruct each other's rotation. On the other hand, the arcuate surface 854 on the outer surface of the hinge support 800 can be inserted below the cover plate 710.

[0165] According to one embodiment of the present invention, when the hinge bracket 800 rotates relative to the first hinge portion 290 by a predetermined angle, the end 852 of the shielding portion 850 contacts the hinge beam 292 of the first hinge portion 290. For example, in the illustrated example, when the hinge bracket 800 rotates 90 degrees, the end 852 of the shielding portion 850 contacts the bottom surface of the hinge beam 292. When the end 852 of the shielding portion 850 contacts the hinge beam 292 in this way, the hinge bracket 800 cannot rotate in the same direction. That is, the thickness of the hinge beam 292 limits the rotation range of the hinge bracket 800.

[0166] When the hinge bracket 800 is rotated 90 degrees as shown in the figure, the upper housing reaches the 90-degree unfolded position, and the powder box container 1000 will be configured as depicted in Figure 20(a). In this configuration, the user can lift the unit cover 500 to access the contents inside the receiving space 350, for example, to look at the mirror 715 installed on the inside of the cover 700 while applying cosmetics.

[0167] When the user continues to apply force to rotate the upper housing further, the hinge bracket 800 can no longer rotate relative to the first hinge portion 290, so the second hinge portion 690 begins to rotate relative to the hinge bracket 800. Although the second hinge portion 690 includes a flat portion 696, when the second hinge portion 690 rotates in the open direction, the flat portion 696 moves in a direction away from the hinge bracket 800, while the arcuate portion 694 of the second hinge portion 690 moves along the arcuate surface 840 of the hinge bracket 800, thus allowing rotation.

[0168] When the second hinge portion 690 rotates 90 degrees relative to the hinge bracket 800, the upper housing reaches the 90-degree unfolded position, and the powder cartridge container 1000 is configured as depicted in FIG20(b). In this configuration, the user can lift the unit cover 500 as shown in FIG20(c) to access the contents inside the receiving space 350, or pull the sliding base 100 as shown in FIG20(d) to separate the replacement unit.

[0169] Reference Figure 19 The thickness of the hinge beam 692 of the second hinge portion 690 can be less than the thickness of the hinge beam 292 of the first hinge portion 290. That is, the hinge beam 292 of the first hinge portion 290 can be manufactured with a pre-designed thickness, thereby configuring it such that when the hinge support 800 rotates a predetermined angle, the end 852 of the shield 850 contacts the hinge beam 292, while the hinge beam 692 of the second hinge portion 690 is not subject to this constraint. This has the advantage of relaxing the permissible manufacturing tolerances for the hinge beam 692. However, other structures that limit the rotation range of the second hinge portion 690 can be applied to the upper housing. For example, although... Figure 19 The illustration is omitted. The upper frame 600 is connected to the cover 700, as shown. Figure 19 As shown, when the upper housing reaches the 180-degree unfolded position, the cover plate 710 of the cover 700 will contact the flat surfaces 816 and 856 on the outer surface of the hinge bracket 800, thereby preventing further rotation.

[0170] When the powder box container 1000 of one embodiment of the present utility model is as follows: Figure 19When the hinge bracket 800 reaches the 180-degree unfolded position, as depicted in Figure 20(b), the inner (front) surface of the bracket body 810 is exposed to the user in a prominent position between the mirror 715 and the replacement unit. Manufacturers can, for example, print or engrave logos or patterns on the flat surface 812 of the bracket body 810, thereby increasing the utilization of the hinge bracket 800 as a design element.

[0171] Furthermore, as mentioned above, the lower frame 200 is normally located inside the sliding base 100, so it may be difficult to apply force in the direction of separating the sliding base 100 from the lower frame 200. However, when the upper housing is in the 180-degree unfolded position as shown in FIG20(d), the user can fix the lower frame 200 by holding the exposed support body 810 at the top and bottom, and can easily slide the sliding base 100 by pulling it in this state.

[0172] After using the powder cartridge container 1000, the user can close the upper housing again. The user can close the upper housing by rotating it in the opposite direction. Figure 19 When the hinge bracket 800 is lifted in the closed direction, it can rotate first relative to the first hinge portion 290, which has less friction. When the hinge bracket 800 rotates 90 degrees relative to the first hinge portion 290, the flat surface 860 of the shielding portion 850 contacts the flat portion 296 of the first hinge portion 290, thereby suppressing further rotation.

[0173] When the user continues to apply force to rotate the upper housing further, since the hinge bracket 800 can no longer rotate relative to the first hinge portion 290, the second hinge portion 690 begins to rotate relative to the hinge bracket 800. When the second hinge portion 690 rotates 90 degrees relative to the hinge bracket 800, the upper housing can reach the closed position and overlap the lower housing, and due to the magnetic bodies (not shown) respectively provided on the upper and lower housings, they can be fixed relative to each other.

[0174] Normally, when the upper and lower housings are rotatably coupled to separate components, the hinge portions of the upper and lower housings rotate at the same angle, raising concerns about misalignment between them. However, in the powder box container 1000 of one embodiment of this invention, the rotation between the hinge bracket 800 and the hinge portions 290 and 690 is precisely controlled at a pre-designed angle. Therefore, even if the upper and lower housings are opened and closed arbitrarily, they will always be accurately aligned with the lower housing when the upper housing returns to the closed position.

[0175] Based on the above-described embodiments of this utility model, a powder cartridge container 1000 is provided that securely fixes the replacement unit during normal use, minimizing the possibility of accidental separation. When a user of this powder cartridge container 1000 wishes to separate the replacement unit, the replacement unit can be released by simply opening the upper housing to a 180-degree unfolded position, grasping the exposed hinge brackets 800, and pulling the sliding base 100.

[0176] On the other hand, according to some embodiments of the present invention, a powder cartridge container 1000 with a double-hinge structure is provided, in which an upper shell and a lower shell are rotatably coupled to a hinge bracket 800. In this powder cartridge container 1000, the structure of the hinge bracket 800 and the hinge portions 290 and 690 allows the upper shell to be accurately moved to a 90-degree unfolded position, a 180-degree unfolded position, and a closed position. In particular, in the 180-degree unfolded position, the bracket body 810 of the hinge bracket 800 can be exposed both upwards and downwards, thus having high utilization as a design element, and as mentioned above, can be used as a part to hold when the sliding base 100 is pulled.

[0177] Although the present invention has been described above with reference to one embodiment, those skilled in the art will understand that various modifications and alterations can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims.
