Abstract
Description
[Technical Field]
[0001] To provide a cosmetic container in which an inner tray can be detachably housed in a container body, the attachment and detachment operation is simple, and the entire container is compact and has a good appearance. [Background technology]
[0002] Conventionally, cosmetic containers have been widely used in which an inner tray filled with cosmetics such as foundation is detachably stored in the container body, and when the inner tray is used up, it can be replaced with a new inner tray, or multiple inner trays prepared for different types of cosmetics can be stored in a combination according to the purpose.
[0003] In such cosmetic containers with replaceable inner trays, if the inner tray is a metal tray, an adhesive layer is applied to the bottom of the recess in the container body for accommodating the inner tray, adhesively fixing the metal tray within the recess, and when replacing the tray, it is common to remove the metal tray using a thin pin through a through hole in the bottom of the recess.
[0004] On the other hand, when the inner plate is made of resin, the flexibility of resin is utilized to provide an engaging recess on the outer surface of the inner plate, and engaging claws or the like are provided on the wall of the recess for accommodating the inner plate in the container body, so that the inner plate can be attached and detached freely to the container body by engaging the two (Patent Documents 1, 2, etc.).
[0005] For example, in the cosmetic container of Patent Document 1, as shown in Fig. 10(a), a claw 4 for engaging with the inner tray 3 is provided on the left wall of the inner tray-receiving recess 2 of the container body 1, and a protrusion 5 for preventing removal is provided on the opposite right wall. The claw 4 and protrusion 5 engage with a groove 3a on the outer periphery of the inner tray 3, thereby removably holding the inner tray 3 in the recess 2 of the container body 1. To remove the inner tray 3, as shown in Fig. 10(b), which is a cross-sectional view taken along the X-X' line in Fig. 10(a), a notch 7 in a partition wall 6 on the container body 1 side is used to push the inner tray 3 to the left as shown by the arrow, thereby disengaging the inner tray 3 from the protrusion 5 and pulling it out diagonally upward. The cosmetic container of Patent Document 2 has a similar configuration. [Prior art documents] [Patent documents]
[0006] [Patent Document 1] Patent No. 3561560 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-177045 Summary of the Invention [Problem to be solved by the invention]
[0007] However, in the above-described detachable structure of the inner tray 3, the concave and convex portions for engaging the inner tray 3 are recessed and protruded horizontally, which necessitates thickening the peripheral wall of the inner tray 3 and the area around the recess 2 of the container body 1, and also requires a certain thickness in the vertical direction to ensure space for the concave and convex portions, which results in the container as a whole being bulky and makes it difficult to achieve a thin, sharp-looking container. In particular, when storing multiple inner trays 3 at the same time, there is a problem of not wanting to take up extra space.
[0008] Furthermore, in the conventional configuration, in order to remove the stored inner tray 3, it is necessary to provide a notch 7 [see Figure 10(b)] on the inner tray 3 for a finger to hook onto, or an alternative stepped portion, which makes it impossible to align the height of the top surface of the container body 1 and the inner tray 3 at a uniform height, which results in an unsightly appearance.
[0009] Therefore, consideration has been given to improving the appearance by thinning the area around the recess in the container body and the peripheral wall of the inner tray, and by making the height of the outline of the inner tray and the partition wall that appear on the top surface of the container body all uniform.However, doing so makes it difficult to ensure a structure that allows the inner tray to be attached and detached freely, and in reality, such a cosmetic container has not yet been realized.
[0010] The present invention has been made in consideration of the above circumstances, and its object is to provide an excellent cosmetic container in which the peripheral wall of the inner tray and the peripheral wall of the recess in the container body can be made thin, even though it is a cosmetic container with a detachable inner tray, and the heights of the inner tray on the top surface of the container body and the surrounding partition walls can also be made uniform. [Means for solving the problem]
[0011] In order to achieve the above object, the present invention provides the following [1] to [8]. [1] A cosmetic container comprising: a middle tray having a cosmetic filling recess formed on the top surface; a container body having a middle tray accommodating recess formed on the top surface for detachably accommodating the middle tray; and a lid for covering the container body, The inner tray and the container body are both made of resin and are integrally molded. An engaging member is formed on the underside of the inner tray so as to protrude downward and engage with the inner tray receiving recess of the container body, the engaging member is a generally cylindrical body having a space portion and a bottom portion extending along the underside of the inner plate, or a cantilevered insertion piece extending along the underside of the inner plate, The bottom surface of the inner tray accommodating recess of the container body is formed with an engaged member for engaging with an engaging member formed on the lower surface of the inner tray to protrude therefrom, and an opening for exposing a part of the engaging member from the lower surface of the container body when the inner tray is accommodated therein; The engaged member is a cantilevered insertion piece extending along the bottom surface of the inner tray accommodating recess, or a substantially cylindrical body having a space portion and a top surface portion extending along the bottom surface of the inner tray accommodating recess, An engaging piece for fixing the inner tray in the inner tray accommodating recess is provided on a part of the lower surface of the inner tray or the lower surface of the engaging member, and an engaged piece that can engage with the engaging piece is provided on a part of the bottom surface of the inner tray accommodating recess or the upper surface of the engaged member, By inserting the insertion piece of the engaging member or the engaged member into the inside of the approximately cylindrical body of the engaging member or the engaged member, the engaging piece and the engaged piece engage with each other, and the inner tray is fixed within the inner tray accommodating recess of the container body. [2] The engaging member is a generally cylindrical body having a space surrounded by a portion of the underside of the inner tray, a pair of side portions hanging down from the underside of the inner tray, and a bottom portion extending parallel to the underside of the inner tray while maintaining a predetermined gap, one end of which is an opening, and the other end of the bottom portion opposite the opening is provided with an engaging piece for fixing the inner tray in the inner tray accommodating recess, The engaged member is an insertion piece extending from one end edge to the other end edge of a notched opening provided in the bottom surface of the inner tray accommodating recess, and an engaged piece for engaging with the engaging piece is formed on the other end edge of the notched opening, The cosmetic container described in [1] is configured so that the opening of the engaging member of the inner tray faces the tip of the insertion piece, and by inserting the insertion piece into the engaging member, the engaging piece and the engaged piece engage with each other, and the inner tray is fixed within the inner tray accommodating recess of the container body. [3] The cosmetic container according to [1], wherein the engaging member is an insertion piece formed on the underside of the inner plate and is angled downward from the base to the tip at an angle of 0.5 to 3 degrees relative to the underside of the inner plate. [4] A cosmetic container according to [1] or [2], wherein the engaging member is an insertion piece formed on the bottom surface of the inner tray accommodating recess, and is angled with respect to the bottom surface of the inner tray accommodating recess so as to have an upward slope of 0.5 to 3 degrees from the base to the tip. [5] A cosmetic container as described in [2], in which a slit is formed in the inner tray accommodating recess of the container body, near the opening edge of the cutout opening in which the engaging piece is formed, extending along the opening edge and having a band-like shape in a plan view, and reaching the underside of the container body. [6] The cosmetic container according to [2], wherein a predetermined area of the bottom surface of the engaging member near the portion where the engaging piece is provided is recessed and thinner than other portions. [7] A cosmetic container as described in [2], in which the portion of the underside of the inner plate extending from the edge of the opening of the engaging member to the edge of the inner plate opposite the side on which the engaging member is provided is recessed and thinner than other portions. [8] The cosmetic container according to [1] or [2], wherein the thickness of the entire cosmetic container when the lid is closed is 9 to 13 mm. [Effects of the Invention]
[0012] In other words, whereas conventional cosmetic containers have engaged the inner tray using the outer surface of the inner tray and the inner wall surface of the recess in the container body, the cosmetic container of the present invention utilizes the underside of the inner tray and the bottom surface of the inner tray accommodating recess in the container body, allowing the inner tray to be easily attached and detached in the vertical direction.
[0013] This configuration eliminates the need for extra space in the horizontal direction and also allows the thickness of the entire container to be reduced, resulting in a compact overall configuration.
[0014] In the above configuration, the inner tray can be easily removed from the container body by simply pushing upward a portion of the inner tray's engaging member exposed in the opening on the underside of the container body. Therefore, the method for attaching and detaching the inner tray is easy to understand, and consumers can easily attach and detach the inner tray themselves. Furthermore, unlike conventional designs, there is no need to provide steps or notches around the inner tray and the inner tray receiving recess on the container body, or on the partition wall, and the top surface of the inner tray and the top surface of the container body can all be aligned at the same height, creating a neat and tidy appearance when the lid is opened.
[0015] Among the present inventions, those in which an engaging member consisting of a specific roughly cylindrical body is provided on the underside of the inner tray and an engaging member consisting of a specific insertion piece is provided on the bottom surface of the inner tray accommodating recess in the container body are particularly preferred as they allow the overall thickness of the cosmetic container to be thin and also make it easy to attach and detach the inner tray.
[0016] Furthermore, in the present invention, particularly when an insert piece is provided on the tray side as the engaging member, the insert piece is preferably angled so that it slopes downward at 0.5 to 3 degrees from its base to its tip. Conversely, when an insert piece is provided on the tray-receiving recess side as the engaged member, the insert piece is preferably angled so that it slopes upward at 0.5 to 3 degrees from its base to its tip. In other words, with such an angle, when the insert piece is inserted into the substantially cylindrical mating member to secure the tray, the tip of the insert piece presses against the bottom surface of the tray-receiving recess or the underside of the tray. Therefore, when the engaging member exposed on the underside of the container body is pushed up to remove the tray, the disengagement of the two components results in the tray being thrust upward with force, making it easier to remove.
[0017] Furthermore, among the present invention, in particular, an engaging member consisting of a specific approximately cylindrical body is provided on the underside of the inner plate, and an engaged member consisting of a specific insertion piece is provided on the bottom surface of the inner plate accommodating recess of the container body, and a specific slit is formed together with the specific engaged piece.The slit increases the degree of freedom of the engaged piece, allowing the inner plate to be attached and detached more smoothly.
[0018] Similarly, in particular, an engaging member consisting of a specific, roughly cylindrical body is provided on the underside of the middle plate, and an engaged member consisting of a specific insertion piece is provided on the bottom surface of the middle plate accommodating recess in the container body, and a specific engaging piece is provided on the engaging member on the middle plate side, and a specific area nearby is recessed and thinner than other parts, the degree of freedom of the engaging piece is increased, allowing the middle plate to be attached and detached more smoothly.
[0019] Similarly, in particular, an engaging member consisting of a specific, roughly cylindrical body is provided on the underside of the middle plate, and an engaged member consisting of a specific insertion piece is provided on the bottom surface of the middle plate accommodating recess in the container body.If a specific portion of the underside of the middle plate is recessed and thinner than other portions, the tip of the insertion piece, which is the engaged member, can be guided into the engaging member while aligning it with this recessed portion, allowing the insertion piece to be inserted smoothly.
[0020] Among the cosmetic containers of the present invention, those having an overall thickness of 9 to 13 mm when the lid is closed are particularly thin and convenient for carrying and storing. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0022] Next, an embodiment of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to the following embodiment.
[0023] FIG. 1 is a perspective view showing one embodiment of a cosmetic container of the present invention. This cosmetic container comprises a container body 10 and a lid 11 hinged to the rear end of the container body 10. A recess 12 for accommodating an inner tray is formed on the top surface of the container body 10. A cosmetic mirror 13 is attached to the inside of the lid 11.
[0024] Two inner trays 20, each with two cosmetic filling recesses 21 at the front and back, are fitted side by side in the inner tray accommodating recess 12 of the container body 10 (one inner tray 20 is shown removed).
[0025] The container body 10, lid 11, and inner tray 20 are all integrally molded from resin. The type of resin and molding method can be selected as appropriate, but in this example, injection-molded acrylonitrile-butadiene-styrene copolymer resin (ABS resin) is used for all of them.
[0026] First, we will explain the container body 10. As shown in Fig. 2, the inner tray accommodating recess 12 of this container body 10 has a bottom surface 12a provided with notched openings 30 for detachably attaching the inner tray 20 and cantilevered insertion pieces 40 (engaged members) at two locations, one on the left and one on the right, to match the attachment positions of the inner tray 20.
[0027] To explain in more detail, the cutout opening 30 has a rectangular shape in plan view that extends longitudinally in the front-to-back direction of the container body 10, and an insertion piece 40 that is inverted U-shaped in plan view extends from the opening edge 30a on the front end side to the opening edge 30b on the rear end side.
[0028] As shown in Figure 3, which is a cross-sectional view taken along the line A-A' in Figure 2, the thickness of the insertion piece 40 is thinner than other parts of the bottom surface 12a of the tray-accommodating recess 12. The thickness is further reduced at a boundary 41 where the insertion piece 40 connects to the opening edge 30a of the notched opening 30. This is to allow the insertion piece 40 to bend easily up and down, as indicated by the arrows in the figure.
[0029] The rear surface of the tip of each of the pair of left and right sides of the insertion piece 40 is gently tapered so that it becomes thinner as it approaches the tip. This taper is designed to make it easier to insert the insertion piece 40 into the engaging member 50 of the inner tray 20, which will be described later. The angle θ1 of the taper with respect to the underside of the insertion piece 40 is preferably 5 to 20°, and more preferably 3 to 10°.
[0030] The insertion piece 40 is angled slightly upward from its base to its tip, with the tip raised above the bottom surface 12a of the tray-receiving recess 12 within the notched opening 30. This is because when the tray 20 is fixed to this portion, the tip of the insertion piece 40 pushes up against the underside of the tray 20, so that the tray 20 is pushed upward when it is removed. The angle θ2 for the upward slope is preferably set to about 0.5 to 3° with respect to the bottom surface 12a of the tray-receiving recess 12, and more preferably 1 to 2°.
[0031] Furthermore, of the thin boundary portion 41 provided on the base side of the insertion piece 40, a portion sandwiched between two opposing sides of the insertion piece 40 protrudes slightly inside the cutout opening 30 to form a step portion 45. This step portion 45 is adapted to engage with a step portion 57 of the engaging member 50, which will be described later (see FIG. 8).
[0032] On the bottom surface 12a of the inner tray accommodating recess 12, an engaging piece 42 for engaging with an engaging piece 55 provided on an engaging member 50 of the inner tray 20 (described later) is formed on the opening edge 30b of the notched opening 30, which faces the tip of the insertion piece 40, and protrudes toward the inside of the opening. The lower end of the opening edge 30b on which the engaging piece 42 is formed protrudes slightly below the bottom end surface of the container body 10, forming a protruding piece 42b (see FIG. 9). The left-right width of the protruding piece 42b is slightly smaller than the left-right width of the opening edge 30b. The protruding thickness (vertical thickness) of the protruding piece 42b is within the range of the vertical thickness of the container support protrusions 80 provided at the four corners of the bottom surface of the container body 10, and does not interfere with the stability of the container.
[0033] Further, a slit 43, which is generally strip-shaped in plan view and extends in the left-right direction along the opening edge 30b at a slight distance from the opening edge 30b, is formed behind (near) the opening edge 30b of the cutout opening 30 on which the engaged piece 42 is formed (see FIG. 3). This slit 43 penetrates all the way to the underside of the container body 10, allowing the engaged piece 42 to move easily back and forth. The width of a lower opening 43a of the slit 43 increases toward the rear, making it easy to hook a finger on the underside of the container body 10 from the hinged side of the engaged piece 42.
[0034] On the other hand, the inner plate 20 attached to the container body 10 has an engaging member 50 protruding downward from its underside 20a for engaging with an insertion piece 40 provided on the container body 10 side, as shown in Figure 4(a), which is a side view of the inner plate 20 seen from the longitudinal side, Figure 4(b), which is a cross-sectional view of the inner plate 20 taken along line B-B', and Figure 5, which is an oblique view of the inner plate 20 shown upside down.
[0035] The engaging member 50 is a generally cylindrical body having a space surrounded by a part of the underside 20a of the inner tray 20, a pair of side surfaces 51 hanging down from the underside 20a of the inner tray 20, and a bottom surface 52 extending parallel to the underside 20a of the inner tray 20 while maintaining a predetermined gap therebetween. One end of the engaging member 50 forms an opening 53, and the other end is closed by a rear surface 54.
[0036] An engaging piece 55 for engaging with the engaged piece 42 provided on the container body 10 side is formed on the end of the bottom surface portion 52 on the side of the rear surface portion 54 so as to protrude toward the rear side.
[0037] In addition, a band-shaped recess 56 extending in the left-right direction is provided in the bottom surface portion 52 near the portion where the engaging piece 55 is provided, and this portion is thinner than other portions. The presence of this band-shaped recess 56 makes it easier for the engaging piece 55 to move at its base portion (the innermost end portion of the bottom surface portion 52). Therefore, the engaging piece 55 can be smoothly engaged with and disengaged from the engaged piece 42 on the container body 10 side.
[0038] Furthermore, a part of the lower surface of the front edge of the bottom surface portion 52 is cut out in a concave shape to provide a step portion 57 (see FIG. 8). As already mentioned, this step portion 57 is intended to engage with the step portion 45 provided at the base portion of the insertion piece 40 on the container body 10 side, and to guide the engaging member 50 so that it does not shift forward or backward or rattle.
[0039] Furthermore, the portion of the underside 20a of the inner tray 20 extending from the opening edge of the opening 53 of the engaging member 50 to the edge of the inner tray 20 on the side opposite to the side on which the engaging member 50 is provided (the portion indicated by diagonal lines in Figure 5) is recessed much more shallowly than other portions, forming a shallow recessed area S.
[0040] To accommodate the inner tray 20 in the inner tray accommodating recess 12 (see Figure 1) of the container body 10, as shown in Figure 6, the opening 53 of the engaging member 50 provided on the underside 20a of the inner tray 20 is faced against the tip of the insertion piece 40 provided on the bottom surface 12a of the inner tray accommodating recess 12, and the insertion piece 40 is inserted inside the engaging member 50.
[0041] When aligning the opening 53 of the engaging member 50 near the tip of the insertion piece 40, first tilt the inner tray 20 so that the recessed area S provided on the underside 20a of the inner tray 20 abuts the base of the insertion piece 40, and then guide the insertion piece 40 along the concave surface of this recessed area S while inserting it into the engaging member 50, thereby making the series of operations smoother.
[0042] By completely inserting the insertion piece 40 into the engaging member 50, as shown in FIG. 7, the engaging piece 55 of the engaging member 50 engages with the engaged piece 42 on the inner tray accommodating recess 12 side, and similarly, the stepped portion 57 on the bottom surface 52 of the engaging member 50 engages with the stepped portion 45 on the inner tray accommodating recess 12 side, thereby stably fixing the engaging member 50 to the bottom surface 12a of the inner tray accommodating recess 12 (see FIG. 8, which is an enlarged view of the area surrounded by the imaginary circle P in FIG. 7). This allows the inner tray 20 to be stably accommodated in the inner tray accommodating recess 12. At this time, the tip of the upwardly inclined insertion piece 40 presses and urges the underside 20a of the inner tray 20 within the engaging member 50.
[0043] When removing the middle tray 20 accommodated in the middle tray accommodating recess 12, the bottom surface 52 of the engaging member 50 exposed in the cutout opening 30 on the underside of the container body 10 is pushed up on the side where the engaging piece 55 is provided, thereby disengaging the engaging piece 55 from the engaged piece 42 on the middle tray accommodating recess 12 side, thereby easily removing the middle tray accommodating recess 20.
[0044] When pushing up the bottom surface portion 52 of the engaging member 50, it is preferable to push up the bottom surface portion 52 while pushing out the protruding piece 42b that protrudes slightly downward from the underside of the container body 10 toward the inside of the notched opening 30, as shown by the thick arrow in Figure 7, so that the engagement between the two is more easily released.
[0045] Thus, with the above-mentioned cosmetic container, the inner tray 20 can be easily removed by simply pushing upward the bottom portion 52 of the engaging member 50 exposed on the underside of the container body 10. Therefore, unlike conventional engagements that utilize the sides of the inner tray and the container body, it is easy for consumers to attach and remove the inner tray 20, making it convenient to use.
[0046] Moreover, because the inner tray 20 and the container body 10 are engaged without creating any irregularities on their sides, no extra space is required in the horizontal direction of the container, and the thickness of the peripheral walls of the container body 10 and inner tray 20 can be made thin, which has the advantage of allowing for a compact overall design. Incidentally, in this example, the overall thickness of the inner tray 20 in the height direction is 3 mm, the thickness of the engaging member 50 in the height direction is 2 mm, and the thickness of the entire cosmetic container is 11 mm, allowing for a thin and compact overall design.
[0047] Furthermore, since there is no need to provide steps or notches around the inner tray storage recess 12 of the container body 10 or on the partition wall, etc., as in the past, for removing the inner tray 20, the upper surfaces of the inner tray 20 and the upper surfaces of the container body 10 can all be aligned at the same height, which has the advantage of giving a neat impression and a good appearance when the lid body 11 is opened.
[0048] In the above example, a slit 43 was provided in the bottom surface 12a of the inner tray receiving recess 12 of the container body 10 to increase the degree of freedom of the engaging piece 42. However, depending on the shape of the engaging piece 42 and the flexibility of the resin material of the container body 10, the slit 43 is not necessarily required. However, when the slit 43 is provided, considering its effectiveness, the width of the slit 43 (indicated by W in FIG. 3) is preferably 1 to 2 mm, more preferably 1 to 1.3 mm. The length of the slit 43 in the left-right direction (indicated by L in FIG. 2) is preferably slightly longer than the width of the notch opening 30. The distance between the slit 43 and the opening edge 30b of the notch opening 30 (indicated by Y in FIG. 3) is preferably 1 to 2 mm, more preferably 1 to 1.3 mm.
[0049] In the above example, the engaging member 50 on the inner tray 20 side has a band-shaped recess 56 extending in the left-right direction near the portion of the bottom surface 52 where the engaging piece 55 is provided, but this is not necessarily required depending on the shape of the engaging piece 55 and the material of the inner tray 20. However, if a band-shaped recess 56 is provided, it is usually preferable to set the depth of the recess to 1 / 2 to 1 / 8 of the overall thickness of the bottom surface 52, although this depends on the arrangement of the band-shaped recess 56 (in this example, the thickness of the bottom surface 52 is 2 mm, and the recess depth of the band-shaped recess 56 is 0.3 mm).
[0050] Furthermore, a step 57 is provided on the front edge of the bottom surface 52, and a step 45 is provided on the insertion piece 40 on the container body 10 side to engage the two, but such engagement is not necessarily required. However, to attach the inner tray 20 in a more stable state, it is preferable to provide the step portions 57, 45 and engage the two.
[0051] In the above example, a recessed area S, which is recessed much shallower than the other areas, is provided on the underside 20a of the inner tray 20 from the opening 53 of the engaging member 50 to the edge of the inner tray 20. However, this recessed area S is not necessarily required. However, as mentioned above, if the insertion piece 40 on the container body 10 is inserted into the engaging member 50 while aligning it with this recessed area S, the series of operations can be performed smoothly. Furthermore, the presence of the recessed area S has the advantage that the gap in the vertical direction is wider by the amount of the recessed area S on the underside 20a of the inner tray 20, which is inserted into the inner tray receiving recess 12 at an angle, so that the insertion piece 40 can more easily enter the opening 53 of the engaging member 50 (see FIG. 6).
[0052] In the above example, the bottom surface portion 52 of the engaging member 50 occupies a relatively large proportion of the lower surface 20a of the inner tray 20 so that the inner tray 20 can be placed stably on a horizontal surface or when filling it with cosmetic material. If the area of the lower surface 20a of the inner tray 20 (the projected area on a horizontal surface excluding irregularities) is 1, it is preferable to set the lower surface area of the bottom surface portion 52 (the projected area on a horizontal surface excluding irregularities) to approximately 1 / 10 to 1 / 6. If this proportion is too small, the bottom of the inner tray 20 will become unstable and unsteady when filling it with cosmetic material, which is undesirable. Conversely, if it is too large, the overall weight of the container will increase, which is undesirable because it increases material costs.
[0053] In addition, in the above series of examples, an engaging member 50 which is approximately cylindrical is provided on the side of the inner tray 20, and an insertion piece 40 is provided as an engaged member on the bottom surface of the inner tray accommodating recess 12 of the container body 10, but it is also possible to provide an insertion piece that protrudes in a cantilevered manner extending in the planar direction from the underside of the inner tray 20, and to provide an approximately cylindrical body (engaged member) on the bottom surface of the inner tray accommodating recess 12 of the container body 10 for inserting the above-mentioned insertion piece.
[0054] In this case, it is desirable to provide a frame around the insertion piece on the underside 20a of the inner tray 20 to stably place the inner tray 20. In other words, the inside of this frame corresponds to the notched opening 30 in the above example (see Figure 2).
[0055] It is preferable to use the thickness of the bottom surface 12a of the inner tray accommodating recess 12 to form a space for holding the insertion piece, and to extend a portion of the bottom surface 12a to the underside of the container body 10, exposing the insertion piece on the inner tray 20 side from the opening.
[0056] The present invention is characterized by the detachable structure between the inner tray 20 and the container body 10, and as long as the characteristic configuration is present, the shape of the inner tray 20 and the shape of the entire cosmetic container are not particularly limited. However, one of the characteristics of the cosmetic container of the present invention is that it can be made thin overall, and it is suitable for application to a cosmetic container with an overall thickness of 9 to 13 mm, for example.
[0057] Any type of cosmetic material can be filled into the inner tray 20, but since the inner tray 20 is a one-piece molded resin product, it is desirable to fill it with a cosmetic material that is suitable for a resin tray. [Example]
[0058] Next, examples of the present invention will be described, but the present invention is not limited to the following examples.
[0059] Example 1 As the embodiment, a cosmetic container having the configuration shown in Figs. 1 to 9 was prepared in accordance with the above description.
[0060] <Evaluation> For the above-mentioned Example 1, five test subjects inserted and removed the tray from the tray-receiving recess of the container body five times. They then evaluated the ease of the attachment and detachment process, and the test results indicated that the tray could be attached and detached smoothly without damaging the engaging member on the underside of the tray. Furthermore, the test results indicated that the top surface of the container body with the tray housed in the tray-receiving recess had a very neat and beautiful appearance, since there was no gap between the periphery of the tray and the peripheral wall of the tray-receiving recess, and the peripheral wall of the tray-receiving recess was also thin. [Industrial Applicability]
[0061] To provide an excellent cosmetic container in which the peripheral wall of the inner tray and the peripheral wall of the recess in the container body can be made thin, even though the cosmetic container has a detachable inner tray, and the heights of the inner tray on the top surface of the container body and the surrounding partition walls can be made uniform.
