Description

  The present invention relates to a compact container for storing cosmetics and cosmetics in a portable manner. Specifically, the present invention relates to a sealed compact container that can store cosmetics in a sealed state.

  Many recent cosmetics contain a large amount of a solvent such as moisture because of a good feeling of use. As a matter of course, since the solvent evaporates or volatilizes, the cosmetic (volatile cosmetic) containing the solvent is stored in a sealed container in order to prevent drying. Of course, even in a compact container in which a cosmetic such as a puff is made portable together with the cosmetic, if the cosmetic is a volatile cosmetic, hermeticity is required.

  Therefore, in a sealed compact container that can store cosmetics in a sealed state, a container main body that collectively stores cosmetics and cosmetics, an outer lid that covers the container main body so as to be openable and closable, and a container main body Inside, an inner lid for sealing the cosmetic storage space is provided. The following Patent Documents 1 to 3 include an inner lid formed with a so-called bulge that swells upward on the upper surface, and when the outer lid is closed, the inner lid is inserted through the bulge by the back surface of the outer lid. Is sealed down, and the packing on the lower surface of the inner lid is in close contact with the edge surface of the opening of the cosmetic storage space to seal the cosmetic storage space.

  In addition, in the compact container of patent document 1 and 2, the compact container provided with the mechanism in which an inner cover opens automatically in response to the operation | movement which opens an outer cover is described. Patent Document 3 discloses that the hinge of the inner lid is moved up and down in order to prevent the hermeticity from being deteriorated by tilting the open end side and the hinge side of the inner lid obliquely with respect to the opening surface of the cosmetic storage space. Describes a closed compact container that can be moved.

  Conventionally, in a sealed compact container, the cosmetic is sealed with an inner lid using a hinge. Therefore, the sealed compact container requires a space for providing a hinge for the inner lid and a closing means such as a hook for maintaining the openable inner lid in a closed state. Miniaturization has been difficult. In addition, each part of a sealed compact container is usually a plastic molded product, and in addition to the outer lid, if the inner lid is provided with a hinge or closing means with a complicated structure, the manufacturing cost of the sealed compact container is increased. Will increase.

  Furthermore, cosmetics easily adhere to the back side of the inner lid, and when the inner lid is open, the back side is exposed to the outside. Therefore, it is also conceivable that the cosmetics attached to the back side of the inner lid reattach to unintended parts (clothes, fingers, etc.) and stain those parts.

  As described above, the present invention has been made in view of various problems in the conventional sealed compact container, and its purpose is to be small and inexpensive, and to store cosmetics in a sealed state. Another object of the present invention is to provide a sealed compact container that does not contaminate other parts with the amount of makeup adhered to the back surface of the inner lid.

=== Technical idea of the present invention ===
The inventor of the present application considered the structure of an ideal hermetic compact container in order to solve various problems in the conventional hermetic compact container having an inner lid using a hinge. And if the inner lid is plate-shaped, and it is a slide-type inner lid that can move within the plate surface (horizontal plane), there is no need for hinges or closing means for the inner lid, and space for forming these is saved. As a result, the outer size of the sealed compact container can be made smaller without sacrificing the storage space for substantial cosmetics and cosmetics, and the structure can be simplified and the price can be reduced. Thought. Furthermore, since the back surface of the inner lid and the bottom surface of the container body are always facing each other, the back surface of the inner lid is not exposed, and it is considered that unintended parts are not soiled by the cosmetics attached to the back surface. It was. In addition, as the slide type inner lid, for example, a groove extending in the horizontal direction on the two opposite surfaces of the inner surface of the flat box-shaped container body is formed as a guide rail, and the edge of the plate-shaped inner lid A structure in which the end is slid in a state of being fitted into the guide rail is conceivable.

  Next, as in the sealed compact container described in each of the above patent documents, the plate-shaped inner lid is also provided with a portion (pressing portion) that is pressed by the back surface of the outer lid such as a bulge on the outer surface. When closed, the entire inner lid was urged toward the bottom side of the container body (hereinafter referred to as “downward”) to seal the cosmetic storage space. However, it has been found that it is difficult to securely seal the cosmetic by simply sliding the inner lid.

  Specifically, when the outer lid is closed, the inner lid is urged downward via the pressing portion, and the inner lid is supported by the guide rail. That is, since the inner lid needs to be slid in the horizontal direction perpendicular to the urging direction with respect to the container body, the downward movement is restricted. As a result, in the plate-shaped inner lid, only the forming part of the pressing portion is bent downward, and the cosmetic storage space is sealed by the bent inner lid. Therefore, if the pressing state by the outer lid is slightly loosened, the inner lid in the bent state is restored by elasticity, and the sealing performance cannot be maintained. Before that, since the peripheral part of the inner lid is fixed by the guide rail, the entire inner lid cannot move downward, and there is a possibility that the cosmetic storage space cannot be securely sealed. . Therefore, it was considered to provide play in the slide mechanism by increasing the vertical width of the groove that becomes the guide rail and to suppress the elastic deformation of the inner lid as much as possible. This makes it difficult to smoothly slide the inner lid along the guide rail.

  Therefore, the inventor of the present application has a structure that can securely seal the cosmetic storage space while keeping the inner lid elastically deformed as much as possible and allowing it to slide smoothly with respect to the sealed compact container having the sliding inner lid. Various thought experiments and prototypes were conducted. The present invention has been conceived. Below, the structure about the airtight compact container which concerns on one Example of this invention, and the structure and operation | movement of each component are demonstrated.

=== Appearance of sealed compact container ===
In FIG. 1, the external appearance of the airtight compact container (henceforth, compact container) 1 which concerns on the present Example of this invention was shown. FIG. 1 shows the appearance when the outer lid 10 is closed. The appearance of the compact container 1 is the same as that of a general compact container, and is connected to a container body 2 having a flat box shape having a space for storing cosmetics and cosmetics inside, and the container body 2 via a hinge. And an outer lid 10 that covers the opening of the container body 2 so as to be openable and closable.

  Here, as shown in FIG. 1, the vertical and horizontal directions and the front and rear directions are defined for convenience. With respect to each direction of the container body 2, the bottom side is the lower side, and the opening side covered with the outer lid 10 is the upper side. Moreover, let the side connected with the outer cover 10 by the hinge be the back, and let the open end side of the outer cover 10 be the front. For the left-right direction, the direction when viewed from the front is adopted. On the other hand, since the outer lid 10 is accompanied by an opening / closing operation, the directions of up / down, front / rear, and left / right are defined regardless of the opening / closing states with reference to the closed state shown in FIG. That is, when the outer lid 10 is in the closed state, the directions of the outer lid 10 and the container body 2 coincide.

  FIG. 2 shows an external view of the compact container 1 when the outer lid 10 is opened. Engaging structures (11, 31) for maintaining the closed state of the outer lid 10 are formed at the front ends of the container body 2 and the outer lid 10. Further, a mirror 12 is attached to the back surface, that is, the bottom surface of the outer lid 10. In the following drawings including FIG. 2, each direction in the outer lid 10 is indicated by a dotted arrow. The compact container 1 includes an inner lid 60 that can slide in the horizontal direction above the container body 2.

  2A and 2B respectively show a state when the inner lid 60 is closed and a state when the inner lid 60 is opened. In this example, the interior of the container body 2 is a makeup The material storage space 51 and the cosmetic storage space 3 are partitioned so as to be arranged in parallel on the left and right. The inner lid 60 slides in the left-right direction in which the cosmetic storage space 51 and the cosmetic storage space 3 are parallel. In this embodiment, the cosmetic storage space is on the left. Further, the inner lid 60 includes a bulge 62 as a pressing portion protruding upward on the upper surface, and when the outer lid 10 is closed, the inner lid 60 is urged downward through the bulge 62 to seal the cosmetic storage space 51. To do.

=== Configuration of compact container ===
<Configuration>
FIG. 3 shows an exploded perspective view of the compact container 1 of the present embodiment. The compact container 1 includes a container main body 2 for storing cosmetics and cosmetics, and an outer lid that is connected to the container main body 2 via a hinge and covers the upper opening of the container main body 2 so as to be freely opened and closed. 10 and a basic component consisting of a rectangular dish-shaped middle dish 50 fixed in the container body 2 as a cosmetic container, and can be slid to the left and right, and the opening of the middle dish 50 can be freely opened and closed. A covering plate-like inner lid 60 and a frame body (guide frame) 40 having a structure for guiding the sliding operation of the inner lid 60 are provided. In the compact container 1 of the present embodiment, the structure of the guide frame 40 and the inner lid 60, the arrangement relationship and engagement structure between these components (40, 60) and other components, or other components. There is a great feature in the interlocking structure and the like, and by the feature, the opening of the inner tray 50 is securely sealed by the inner lid 60, and the sealed state is not easily released. In addition, when the sealed state is intentionally released, the inner lid 60 slides smoothly.

  In the present embodiment, the container body 2 includes a thin flat box-shaped bottom plate 20 that forms an outer shape, and a frame (main body frame) 30 that is different from the guide frame 40 mounted along the inner shape of the bottom plate 20. The bottom plate 20 is an outermost frame for accommodating the main body frame 30, the guide frame 40, and the inner tray 50 in a nested manner. Further, a plate-like portion 22 extending in the front-rear direction is formed at the center of the bottom surface of the bottom plate 20, and this plate-like portion 22 serves as an interior space of the container body 2 as a cosmetic storage space 51, i.e., a middle dish. It becomes the partition plate 22 for partitioning into the space 21 in which 50 is arrange | positioned, and the storage space 3 of cosmetics. In this example, the space partitioned on the right side is the storage space 3 for the cosmetic tool, and the inner tray 50 is disposed in the space 21 partitioned on the left side.

  The main body frame 30 supports the thin bottom plate 20 from the inside to constitute the high-strength container main body 2 and can be connected to the outer lid 10 via a hinge at the rear end to open and close the outer lid 10. It is said. Specifically, the rear side surface of the bottom plate 20 is cut out in a rectangular shape with a part thereof reaching the bottom surface, and the rear side surface of the main body frame 30 is formed with an opening 32 corresponding to the cutout portion. The opening 32 constitutes one part of a hinge and is connected to the hinge part on the outer lid 10 side to form a hinge. In the present embodiment, two hollow cylindrical bearings 13 are formed at the rear end of the outer lid 10 so as to be spaced apart from each other on the left and right, and these two bearings 13 serve as hinge parts on the outer lid 10 side. ing. A closing structure for maintaining the outer lid 10 in a closed state is formed on the front end of the outer lid 10 and the front outer surface of the container body 2. In this example, a rectangular cutout 23 is formed on the front side surface of the bottom plate 20 from the upper edge to the bottom, and an outer lid is formed on the front outer surface of the main body frame 30 in an area exposed from the cutout 23. A protrusion (closing protrusion) 31 that engages with the hook 11 formed at the front end of the head 10 is formed. Of course, the closing structure is not limited to the example shown here.

  On the other hand, a hole (through hole) 33 that is coaxial with a hole (through hole) 14 that penetrates the bearing 13 of the outer lid 10 is formed on the left and right inner surfaces of the opening 32 on the rear side surface of the main body frame 30. A hinge is formed by inserting the two pins 15 into the receiving hole 33 and the through hole 14 while holding the two bearings 13 between the two receiving holes 33 on the main body frame 30 side. In this embodiment, in a state where the bearings 13 are sandwiched between the receiving holes 33, the pins 15 are inserted into the through holes 14 from the inner side to the outer side where the two bearings 13 face each other, and the tip ends of the pins 15 are received. 33 is inserted. As a result, the outer lid 10 can be opened and closed with respect to the main body frame 30. Of course, the structure of the hinge is not limited to this example. For example, instead of passing a common pin through the bearing 13 of the outer lid 10 and the receiving hole 33 of the main body frame 30, a projection corresponding to the tip of the pin 15 is provided on the outer lid 10. A structure may be adopted in which the protrusion is formed at the front end and is rotatably inserted into the receiving hole 33. In any case, it is only necessary that the rear end of the outer lid 10 and the rear end of the main body frame 30 are connected to each other by hinge parts to form a hinge.

  The guide frame 40 is mounted inside the main body frame 30 described above. Cylindrical protrusions (hereinafter referred to as guide protrusions) 34 projecting inwardly are formed on the left and right inner side surfaces of the main body frame 30 at two front and rear sides. A hole (hereinafter referred to as a guide hole) 41 into which 34 is inserted is formed. Further, the guide frame 40 is formed with a groove (hereinafter referred to as a guide rail) 42 extending in the left-right direction above the front and rear inner side surfaces.

  The inner lid 60 has a packing 64 disposed on the lower surface of a plate-shaped inner lid main body 61. In this embodiment, the packing 64 is a rectangular flat rubber sheet, and this packing 64 is the lower surface of the inner lid main body 61. It is affixed to. And this packing 64 closely_contact | adheres to the edge end surface of the opening of the inner tray 50, and the inside 51 of the inner tray 50 is sealed. Further, the edges 63 at both front and rear ends of the inner lid main body 61 have a shape that engages with the guide rail 42 in the guide frame 40. The inner lid 60 slides left and right while being engaged with the guide rail 42 groove. Furthermore, a pressing portion 62 that protrudes upward is formed on a part of the upper surface of the inner lid body 61 so that when the outer lid 10 is closed, the inner lid 50 is biased downward. Yes. In this embodiment, a bulge 62 is formed that bulges upward like a partial surface of a spherical surface.

<Assembly state>
The structure outline of each component of the compact container 1 has been described above. Next, the positional relationship and assembly state between these components in the compact container 1 will be described. In FIG. 4, the positional relationship and assembly | attachment state of each component in the container main body 2 were shown. FIG. 4A is an enlarged view of the left end side of the cross section taken along the line aa in FIG. 1, and shows a cross section at a position where the guide protrusion 34 is formed. 4B is an enlarged view of the front end side of the cross section taken along the line bb in FIG. 2, and shows a cross section at a position crossing the inner lid 60 in the front-rear direction. In these drawings, the outer lid 10 is omitted.

  As shown in FIG. 4, a main body frame 30 is mounted in a nested manner on the inner side of the bottom plate 20, a guide frame 40 is mounted on the inner side, and an inner tray 50 is disposed on the inner side of the guide frame 40. ing. The middle tray 50 is fixed by being adhered to the bottom surface of the bottom plate 20. That is, the inner tray 50 is fixed so as not to move relative to the main body frame 30, and is not fixed to the guide frame 40 mounted on the inner side of the main body frame 30.

  As shown in FIG. 4A, the main body frame 30 and the guide frame 40 are assembled to each other by inserting the guide protrusions 34 into the guide holes 41. In this example, an inclined surface 43 is formed at the lower end of the left and right outer surfaces of the guide frame 40 at the front and rear positions where the guide hole 41 is formed. Thus, when the guide frame 40 is inserted inside the main body frame 30, the guide protrusion 34 is inserted into the guide hole 41 after the inclined surface 43 smoothly passes over the guide protrusion 34. The guide protrusion 34 does not penetrate the guide frame 40 so as not to interfere with the inner tray 50 disposed inside the guide frame 40. Therefore, the guide hole 41 is not necessarily a through hole. The guide hole 41 has a long hole shape with play in the vertical direction with respect to the guide protrusion 34. Thereby, the guide frame 40 can be moved in the vertical direction within the formation range of the guide hole 41 with respect to the container body 2 and the inner tray 50.

  Further, as shown in FIG. 4B, the edge 63 at both front and rear ends of the inner lid body 61 has a shape in which the lower end protrudes outward in a bowl shape, and the edge 63 is a guide rail of the guide frame 40. 42 is engaged. As a result, the inner lid 60 can slide in the left-right direction. A slope 44 is formed on the upper end surface of the guide frame 40 so as to incline downward toward the inside of the guide frame 40, and the lower end of the edge 63 protruding like a bowl of the inner lid body 61 is formed on the slope 44. An inclined surface 65 is formed at an angle along. Accordingly, when the inner lid 60 is inserted into the guide frame 40 from above, the inner lid 50 is smoothly bent while being bent by the slope 44 above the guide frame 40 and the inclined surface 65 formed on the edge 42 of the inner lid 50. An edge 63 that is inserted into the frame and protrudes like a bowl engages with the guide rail 42, and the inner lid 60 is slidably mounted in the left-right direction.

=== Outer lid closing structure and inner lid sealing structure ===
The compact container 1 of the present embodiment having the above-described configuration and assembly structure will be described in more detail below with respect to the sealing structure of the inner tray 50, the operation of each component when sealed, and the like.

<Outer lid closing structure>
As described above, the outer lid 10 and the container body 2 are connected at their rear ends by hinges, and are provided with a closing structure (11, 31) for maintaining the outer lid 10 in a closed state at the front end. FIG. 5 shows the closing structure. 5A and 5B are enlarged views of the rear end side and the front end side, respectively, taken along the line cc in FIG. As shown to (A), the tip of the pin 15 inserted by the through-hole 14 of the bearing 13 of the outer cover 10 is rotatably inserted in the receiving hole 34 of the main body frame 30, and the hinge is comprised. In addition, a convex portion (hereinafter referred to as an opening assisting portion) 16 that protrudes downward and bends forward is formed between the left and right bearings 13 at the rear end of the outer lid 10. Further, a recess 25 is formed on the rear end side of the bottom surface of the bottom plate 20 along the outer shape of the opening assisting portion 16 so as not to interfere with the operation of the opening assisting portion 16 when the outer lid 10 is opened and closed. . The opening assisting portion 16 and the guide frame 40 constitute an opening interlocking mechanism that opens the inner lid 60 in conjunction with the operation of opening the outer lid 10. The details of the opening interlock mechanism will be described later.

  On the other hand, at the center of the front end of the outer lid 10, a tongue piece 18 is formed that extends downward and rearward and bends downward. The lower end of the tongue piece 18 forms a hook portion 11 that protrudes backward in a hook shape. . The front outer side surface of the main body frame 30 is exposed at a position corresponding to a rectangular cutout 23 formed at the center of the front side surface of the bottom plate 20, and a closed projection having a substantially triangular cross section protruding forward at the exposed portion. 31 is formed. The lower end of the hook portion 11 of the outer lid 10 is cut obliquely, and the hook portion 11 slides on the closing protrusion 31 of the main body frame 30 while the tongue piece 18 is bent forward in accordance with the operation of closing the outer lid 10. The lower surface of the projection 31 and the upper surface of the hook portion 11 are engaged, and the outer lid 10 is maintained in the closed state. When the outer lid 10 is opened, the closed state is released and the outer lid 10 is opened if a finger is placed on the front lower end of the outer lid 10 from the notch 23 on the front side surface of the bottom plate 20 and lifted upward.

<Sealing structure of the inner plate>
In the compact container 1 of the present embodiment, the inner tray 50 is sealed by the inner lid 60 in accordance with the closing operation of the outer lid 10 described above. FIG. 6 and FIG. 7 show the aa cross-section and the bb cross-section in FIG. 1, respectively. These cross sections taken along the arrows aa and bb are the same as those shown in FIG. 4, but the entire cross section is shown here. As shown in these drawings, when the outer lid 10 is closed while the inner lid 60 is slid to the left end side and disposed above the middle tray 50, the inner lid 60 is pressed downward via the bulge 62. . Since the inner lid 60 is engaged with the guide rail 42 of the guide frame 40, the guide frame 40 is urged downward together with the inner lid 60. As described above, the guide frame 40 can move up and down within the formation range of the elongated hole-shaped guide hole 41, and when the outer lid 10 is in the closed state, the lower limit of movement or above it. If it is located in, the inner lid 60 will move downward together with the guide frame 40 with almost no bending by pressing downward. And since the packing 64 which consists of a rubber sheet is arrange | positioned in the lower surface of the inner lid | cover 60, the packing 64 closely_contact | adheres to the opening edge end surface of the inner tray 50, and the space in the inner tray 50 is sealed. Further, when the inner lid 60 is pressed downward, the air in the inner tray 50 escapes outward, the sealed inner tray 50 is in a negative pressure state, and the packing 64 causes the inner lid 60 to have an opening edge of the inner tray 50. Adsorbs to the end face. Thus, since the inner lid 60 moves downward together with the guide frame 40 and closes the opening of the inner tray 50, the inner lid 60 hardly bends. That is, even if the closed state of the outer lid 10 is released, the inner lid 50 is not restored by its own elasticity, so that the adsorbed state is maintained and the cosmetic in the inner tray 50 is reliably prevented from drying. be able to.

=== Open interlocking mechanism ===
As described above, in the compact container 1 of the present embodiment, when the outer lid 10 is closed, the inner lid 60 seals the opening of the middle tray 50 via the packing 64, and the inner lid 60 is sealed by the negative pressure. Adsorb to. When the outer lid 10 is opened and the inner lid 60 in the suction state is opened, a finger or a nail may be put on the edge of the inner lid body 61 or the guide frame 40 and lifted upward. However, if it is adsorbed more firmly, some force is required to open the inner lid 60. If the suction state is suddenly released while applying force to open the inner lid 60, the cosmetics stored in the container body 2 may be scattered. There is a slight possibility that the compact container 1 is disassembled by disengaging the inner lid 60 and the guide frame 40 or between the guide frame 40 and the main body frame 30.

  Therefore, the inventor of the present application utilizes the characteristic structure in the compact container 1 of the present embodiment in which the inner tray 50 is sealed by moving the guide frame 40 itself supporting the inner lid 60 downward. Even if the lid 10 is opened carelessly, the sealing performance of the inner tray 50 is reliably maintained, and when the outer lid 10 is intentionally fully opened, the inner lid 60 is operated with a light force in conjunction with the fully opening operation. I came up with an open interlocking mechanism that automatically releases the sealed state. The outline of the open cooperative mechanism has been described above, but here, the structure related to the interlocking mechanism, the operation of each component, and the like will be described in more detail.

  8A to 8C show the interlocking state between the operation of opening the outer lid 10 and the operations of the inner lid 60 and the guide frame 40. FIG. First, in a state where the outer lid 10 is slightly opened, the inner lid 60 is adsorbed by the negative pressure in the inner tray 50, and the sealed state is maintained (A). Furthermore, when the outer lid 10 is opened, the tip 17 of the opening / closing auxiliary portion 16 at the lower end of the outer lid 10 comes into contact with the lower end of the rear surface of the guide frame 40 (B). In the present embodiment, at this time, the front-rear direction of the outer lid 10 and the front-rear direction of the container body 2 are at an angle that is substantially orthogonal. When the outer lid 10 is further opened from this orthogonal state, the tip 17 of the opening assisting portion 16 moves further upward and pushes up the guide frame 40. At this time, there is a sense of resistance when the suction state is opened, but if the outer lid 10 is opened by holding the front end side of the outer lid 10 by hand, the front end is used as a power point, and the tip 17 of the opening assisting portion 16 is moved. The guide frame 40 is pushed up with a light force by the lever principle with the action point and the hinge shaft 15 as a fulcrum. That is, the inner lid 60 engaged with the guide rail 42 of the guide frame 40 is pushed upward, and the lower surface of the packing 64 is separated from the opening edge end surface of the inner tray 50. Further, if the outer lid 10 is fully opened, the opening assisting portion 16 always supports the guide frame 40 from below, so that the inner lid 60 floats with respect to the opening edge end surface of the inner tray 50, The lid 60 can be easily slid.

  Furthermore, in the compact container 1 of the present embodiment, when the rear end side of the guide frame 40 is urged upward by the opening assisting portion 16, the front end side is not pushed up, and the inner lid 60 is against the opening surface of the inner tray 50. In order to prevent the inner lid 60 from tilting obliquely toward the front end with the rear end up, the inner lid 60 is moved parallel to the opening edge surface of the inner tray 50 to maintain a completely floating state. It has a parallel mechanism that can slide 60 very smoothly. The parallel movement mechanism is formed by guide protrusions 34 projecting from the left and right inner surfaces of the main body frame 30 and a long guide hole 41 on the guide frame 40 side into which the protrusions 34 are inserted.

  The parallel movement mechanism will be specifically described with reference to FIG. 8. The guide protrusions 34 on the left and right inner surfaces of the main body frame 30 are formed at the same height position with respect to the main body frame 30. The guide holes 41 on the left and right side surfaces are formed at the same height with respect to the guide frame 40. Further, the long hole-shaped guide hole 41 is inclined in the major axis direction from the lower front to the upper rear rather than the vertical direction. Then, the outer lid 10 is opened from the state (A) in which the outer lid 10 is closed, and further from the state (B) in which the tip 17 of the opening assisting portion 16 is in contact with the lower end of the rear surface of the guide frame 40. As the opening is opened, the tip 17 of the opening assisting portion 16 moves further upward, and the lower end of the rear surface of the guide frame 40 is biased upward. At this time, since the guide hole 41 is inclined upward and rearward, the guide frame 40 is guided by the guide protrusion 34 inserted into the guide hole 41, as indicated by the white arrow in FIG. 8C. In parallel, it moves diagonally upward and backward. Further, since the guide hole 41 is inclined obliquely, the guide frame 40 is supported via the guide protrusion 34 inserted into the guide hole 41, and the front end side of the guide frame 40 pushed upward falls by its own weight. There is no.

  On the other hand, when the outer lid 10 is closed in the order of FIGS. 8C, 8 </ b> B, and 8 </ b> A, the guide frame 40 is not supported by the opening / closing auxiliary portion 16, and tends to drop due to its own weight. However, also in this case, since the guide frame 40 is supported via the guide protrusion 34 inserted into the inclined guide hole 41, the guide hole 41 slides relative to the guide protrusion 34 with friction, The guide frame 40 translates diagonally downward and forward smoothly without dropping suddenly. Also, when the outer lid 10 is closed, the guide frame 40 moves in parallel, and the plate-shaped inner lid 60 is biased downward while maintaining the horizontal. Therefore, the packing 64 is in close contact with the opening edge end surface of the inner tray 50.

=== Other Embodiments ===
In the above embodiment, the container main body 2 is composed of the thin bottom plate 20 and the main body frame 30 provided with the closing protrusion 31 for closing the outer lid 10 while reinforcing the bottom plate 20 from the inside. Without providing the main body frame 30, the bottom plate 20 may be thickened, or the thick bottom plate 20 may be provided with a closing structure of the outer lid 10 corresponding to the closing protrusion 31.

  In the above embodiment, the bulge 62 is formed on the inner lid 60 in order to bias the inner lid 60 downward by the operation of closing the outer lid 10. Of course, not only the bulge 60 but also a protrusion. Further, a protrusion or a bulge protruding downward may be provided on the lower surface of the outer lid 10.

  In the parallel movement mechanism of the guide frame 40 in the above embodiment, the guide hole 41 is inclined in the direction along the movement direction of the guide frame 40. However, the guide hole 41 is not limited to this example, and the guide hole 41 has a long axis in the vertical direction. It may be a long hole. Of course, the direction of inclination may be reversed. In any case, the guide frame 40 can be smoothly translated up and down by being guided by the guide protrusions 34 inserted into the guide holes 41. In the above-described embodiment, when the outer lid 10 is fully opened, the tip 17 of the opening assisting portion 16 draws a trajectory heading upward and rearward, so the lower end of the rear surface of the guide frame 40 is in friction with the tip 17 of the opening assisting portion 16. Therefore, it is urged rearward and upward. That is, it coincides with the inclination direction of the guide hole 41. Therefore, it is more preferable that the guide hole 41 is inclined from the lower front side toward the upper rear side in order to move the guide frame 40 more smoothly with a lighter force.

  The guide rail 42 formed in the guide frame 40 is not formed into a groove shape, but is a monorail that protrudes in the front-rear direction and extends to the left and right, and grooves that engage with the monorail are formed on the front and rear edges of the inner lid 60. Good.

  The opening shape of the inner tray 50 and the storage space 3 for the cosmetics is not limited to a rectangle, but may be an appropriate shape. In this case, what is necessary is just to shape | mold the inner lid | cover 60 so that it may become a planar shape match | combined with the opening shape. For example, if the opening shape of the inner tray 50 or the storage space 3 of the cosmetic tool is circular, the inner lid 50 has a disk shape, and protrusions or the like that engage with the guide rails are provided at the front and rear edges of the disk. Good.

  In the said Example, although the container main body 2 divided the space 21 which arrange | positions the inner tray 50, and the storage space 3 of cosmetics in the right and left, you may arrange | position in the front-back direction. And the guide frame 40 is equipped with the guide rail 42 extended in the front-back direction at both right and left ends, and the inner cover 60 may slide in the front-back direction.

  In the above embodiment, the packing 64 has a simple flat plate shape. However, the present invention is not limited to this, and FIG. 9 illustrates a compact container 1b having a different shape of the packing 64b. As illustrated, the packing 64b is formed with a rib 66 that contacts the inner surface of the opening of the inner tray 50. The packing may be frame-shaped. In any case, the packing may be disposed on the lower surface of the inner lid body 61 so as to be in close contact with the opening edge surface of the inner tray 50. Further, in the compact container 1b shown in FIG. 9, the guide hole 41b has a long hole shape with the vertical direction as the long axis, and a modification of the parallel movement mechanism is also shown. FIGS. 9A and 9B show a state where the outer lid 10 is opened and a state where the outer lid 10 is closed, respectively. The guide frame 40 is translated in the vertical direction (the white arrow in the figure).

  In the above embodiment, the middle dish 50 is fixed so that it cannot be removed by being bonded to the container main body 2. However, if the middle dish 50 is fixed to the container main body in the assembled state, the middle dish 50 is detachable. It is good. FIG. 10 shows an example of the attachment / detachment structure of the inner tray 50b. FIG. 10A is a perspective view of the structure. Here, the bottom plate 20b, the main body frame 20, and the inner tray 50b are shown. (B) is sectional drawing which shows the state which mounted | wore the inner tray 50b, and respond | corresponds to the dd arrow cross section in (A). On the bottom surface of the bottom plate 20b, in addition to the partition plate 22b for partitioning the storage spaces (21, 3) for cosmetics and cosmetics, a plate-like portion 26 similar to the partition plate 22b is formed on the left end side. ing. The left end side plate-like portion 26 is slightly separated from the left inner surface of the bottom plate 20b. When the main body frame 30 is mounted on the bottom plate 20b, the left side surface 26 of the main body frame 30 is inserted into the separated gap. Is done. The plate-like portion 26 and the partition plate 22b are respectively provided with protrusions (27, 28) so as to face each other, and the portions of the protrusions are formed in grooves 52 formed on the side surface of the inner plate 50b. By engaging, the inner tray 50b is detachably fixed to the container body 2.
