Embodiments for Carrying Out the Invention
[0010] Hereinafter, embodiments of the cosmetic container and the bottom body used therefor according to the present invention will be specifically described based on the drawings. Note that the present invention is not limited to these embodiments in any way.
[0011] <Overall Configuration of Cosmetic Container 100> FIG. 1 is a perspective view of a cosmetic container 100 according to the present embodiment. As shown in FIG. 1, the cosmetic container 100 includes a container body 200, a lid 7 that can be attached to an opening of the container body 200, and a bottom body 1 attached to the bottom of the container body 200. Note that the cosmetic container 100 of the present embodiment is formed so as to be able to hold a spatula 9 for applying cosmetics.
[0012] FIG. 2(a) is an exploded perspective view of the cosmetic container 100 according to the present invention. As shown in FIG. 2(a), the container body 200 includes an outer container 3 and a refill container 5 formed so as to be able to be housed inside the outer container 3. Details of each part will be described below. In the following description, the upper and lower sides of the cosmetic container 100 of the present embodiment are defined by the directions of the arrows shown in FIGS. 1 and 2, that is, the vertical directions in FIGS. 1 and 2.
[0013] <Outer container 3> FIG. 3 is a cross-sectional view taken along line III-III of FIG. 1. Hereinafter, the configuration of the outer container 3 will be described in detail while referring to the exploded perspective view of FIG. 2(a) and the cross-sectional view of FIG. 3. As shown in FIG. 2, the outer container 3 of the present embodiment includes a main body 31 formed in a bottomed cylindrical shape and a neck portion 33 formed above the main body 31 and formed so as to be able to attach the lid 7. And inside the main body 31, there is a refill accommodating portion 305 that can accommodate the refill container 5. Further, the refill container 5 can be taken in and out from the upper opening 301 of the outer container 3.
[0014] As shown in FIG. 3, the main body 31 of the present embodiment has an outer peripheral wall 311, an inner peripheral wall 313, and a bottom wall 39. The main body 31 is formed in a double structure by the outer peripheral wall 311 that constitutes the outer peripheral surface of the container body 200 and the inner peripheral wall 313 provided on the inner side in the radial direction of the outer peripheral wall 311. Both the outer peripheral wall 311 and the inner peripheral wall 313 are formed in a cylindrical shape and are arranged concentrically with a predetermined interval therebetween. The inner circumferential wall 313 and the outer circumferential wall 311 are formed integrally via a shoulder portion 317. This shoulder portion 317 is formed to protrude substantially horizontally from the upper part of the inner circumferential wall 313 outward from the inner circumferential wall 313. The outer circumferential wall 311 is formed to extend downward from the tip of the shoulder portion 317. In this way, a gap 307 is formed between the inner circumferential wall 313 and the outer circumferential wall 311 for the length of the shoulder portion 317 that protrudes outward.
[0015] The lower part of the inner circumferential wall 313 is covered by a bottom wall 39. This bottom wall 39 is provided continuously from the inner circumferential wall 313 and constitutes the bottom of the outer container 3. The inner circumferential wall 313 and the bottom wall 39 are formed in a shape that substantially conforms to the shape of the refill container 5 so that the refill container 5 can be housed inside the refill storage section 305 formed by them. Specifically, the bottom wall 39 is formed in a substantially flat shape. A concave portion 391, which is recessed in a concave curved shape, is provided in the center of the surface of the bottom wall 39 facing the bottom body 1. Furthermore, the boundary between the bottom wall 39 and the inner circumferential wall 313 is formed in an arc shape so as to be a curved surface.
[0016] A cylindrical neck portion 33 is provided at the upper part of the inner circumferential wall 313. A male screw 331 is formed on the outer circumferential surface of the neck portion 33, to which the lid 7 can be attached. In this embodiment, the male screw 331 is formed as a double-start screw. By forming the male screw 331 as a double-start screw in this way, the lid 7 can be opened and closed with fewer rotations. In other words, compared to a configuration with a single-start screw, the rotation angle of the lid 7 required to open and close it can be reduced. Therefore, for example, when operating with one hand, opening and closing becomes easier.
[0017] Furthermore, above the portion of the neck 33 where the male screw 331 is provided, a thin wall portion 35 is provided, which is formed to be thinner in the radial direction than the portion where the male screw 331 is provided. In this way, the upper edge portion 333 is formed by providing the thin wall portion 35. The thin-walled portion 35 is formed to be thinner than the portion of the neck 33 where the thin-walled portion 35 is not provided, by the thickness of the outer periphery 57 of the refill container 5, which will be described later. Furthermore, the vertical height of the thin-walled portion 35 is formed to be approximately the same as the vertical height of the outer periphery 57. In other words, the thin-walled portion 35 is formed as a recess on the outer periphery of the neck 33, with a size and shape that allows the outer periphery 57 to be fitted into it.
[0018] As shown in Figure 2(a), the neck portion 33 of this embodiment is provided with a recess 37 in which the upper edge portion 333 is recessed downward. In other words, a part of the thin wall portion 35 is recessed downward so as to fit into the male screw 331 side, forming the recess 37. Multiple recesses 37 of this embodiment are provided spaced apart from each other in the circumferential direction of the neck portion 33. In the illustrated example, two recesses 37 are provided so as to be on opposite sides of the neck portion 33. These recesses 37 are formed to be substantially the same shape and dimensions as the protrusion 59 of the refill container 5, which will be described later, so that the protrusion 59 can be placed in these recesses 37.
[0019] Specifically, as shown in the enlarged view of Figure 2(b), the recess 37 has an opening 390 that opens upward. It also has a bottom portion 371 formed substantially parallel to the upper edge portion 333 of the neck portion 33, and a pair of side portions 373 extending from both ends of the bottom portion 371 to the upper edge portion 333. Both side portions 373 are formed at an angle so that the circumferential width widens from the bottom portion 371 side to the opening 390 side. Furthermore, the corners formed by the bottom portion 371 and the side portions 373 are rounded to facilitate the attachment and detachment of the refill container 5, which will be described later.
[0020] Furthermore, the thin-walled portion 35 has a raised ridge portion 353 that extends along the circumferential direction. This raised ridge portion 353 is formed so that the locking projection 573 of the refill container 5, which will be described later, can engage with it. In this embodiment, the raised ridge portion 353 extends parallel to the upper edge portion 333 and is formed in an annular shape that is continuous in the circumferential direction.
[0021] In this embodiment, the outer container 3 is formed so that the cross-sectional shape of the outer peripheral wall 311 is circular. However, considering ease of gripping and slip resistance when held in the hand, the cross-sectional shape may be formed to be non-circular, elliptical, polygonal, or the like.
[0022] Figure 4 is a view of the outer container 3 of this embodiment, as seen from the bottom side, with the bottom body 1 not attached. Now, with reference to Figure 4, the configuration of the bottom side of the outer container 3 will be explained. As shown in Figure 4, the outer container 3 has an opening at the bottom and a bottom wall 39 is provided inside. To explain further, the lower end 3111 of the outer peripheral wall 311 forms the edge of the opening 303 at the bottom side of the outer container 3. When the bottom body 1 is not attached, the bottom wall 39 is exposed to the outside.
[0023] As shown in Figure 4, a vertical groove 319 is formed on the inner surface 315 of the outer peripheral wall 311, extending upward for a predetermined length from the lower end 3111 of the outer peripheral wall 311. The protruding portion 175 of the bottom body 1 (see Figure 2(a)), which will be described later, can be inserted into this vertical groove 319.
[0024] <Refill container 5> As shown in Figures 2(a) and 3, the refill container 5 has an opening 501 from which cosmetics can be put in and taken out. The refill container 5 of this embodiment comprises a cylindrical peripheral wall 51, a bottom wall 53 formed continuously from the peripheral wall 51 and constituting the bottom surface of the refill container 5, a flange 55 provided at the upper end of the refill container 5, and an outer peripheral body 57 supported by the flange 55 and surrounding the outer circumference of the peripheral wall 51. The peripheral wall 51 and bottom wall 53 are formed in a shape that substantially follows the inner peripheral wall 313 and bottom wall 39 of the outer container 3, and cosmetics can be stored inside.
[0025] Here, the flange 55 and outer periphery 57 of the refill container 5 will be described in detail. First, the flange 55 is provided on the peripheral wall 51 of the refill container 5 and protrudes radially outward in a flange shape from the end on the opening 501 side. The outer periphery 57 is formed by folding back from the outer end of the flange 55 toward the bottom wall 53 side. This outer periphery 57 is formed to have a thickness and height that allows it to be fitted into the thin wall portion 35 provided on the upper part of the neck portion 33. That is, when the refill container 5 is placed inside the outer container 3, the outer periphery 57 is positioned to cover the thin wall portion 35, and the lower edge 571 of the outer periphery 57 and the upper edge 333 of the neck portion 33 come into contact or nearly come into contact. With this configuration, when the refill container 5 is housed inside the outer container 3, the flange 55 is supported by the tip 351 of the thin wall portion 35 of the outer container 3, and the outer peripheral body 57 fits into the thin wall portion 35, supporting the lid 7 together with the neck portion 33.
[0026] The outer periphery 57 is provided with a protrusion 59 that extends from a part of its lower edge 571 toward the bottom wall 53. In this embodiment, multiple protrusions 59 are provided on the outer periphery 57 in the circumferential direction, spaced apart from each other. In the illustrated example, two protrusions 59 are provided so as to be in opposing positions. The number and position of the protrusions 59 are not limited, but by providing multiple protrusions in opposing positions as in this embodiment, the user can grasp the refill container 5 more securely when attaching or detaching the refill container 5 to the outer container 3. Furthermore, the protrusions 59 provided in opposing positions can be held with the thumb and index finger, improving operability.
[0027] The protrusion 59 is formed to be substantially the same shape and dimensions as the recess 37 of the outer container 3 so that it can be inserted into the recess 37. Specifically, as shown in Figure 2(b), the protrusion 59 has a tip portion 591 formed substantially parallel to the lower edge portion 571, and a pair of side portions 593 extending from both ends of the tip portion 591 to the lower edge portion 571. The side portions 593 are formed to be inclined so that the width in the circumferential direction narrows from the lower edge portion 571 side to the tip portion 591 side. In addition, the corners formed by the tip portion 591 and the side portions 593 are rounded to facilitate the attachment and detachment of the refill container 5, which will be described later.
[0028] Furthermore, as shown in Figure 3, a locking projection 573 is formed on the inner surface of the outer periphery 57 so as to protrude toward the peripheral wall 51. This locking projection 573 is formed to lock with the protruding ridge 353 of the thin wall portion 35 when the refill container 5 is housed in the outer container 3. In this way, the locking projection 573 of the outer periphery 57 locks with the protruding ridge 353 of the thin wall portion 35, thereby more securely holding the refill container 5 in relation to the outer container 3.
[0029] <Bottom body 1> As shown in Figure 2(a), the bottom body 1 of this embodiment comprises a substantially disc-shaped main body 11 formed to be attachable to the bottom of the outer container 3, a peripheral wall 17 provided on the top surface of the main body 11, and a spatula holding portion 191 provided to protrude radially outward from the main body 11. The main body 11 is formed in the shape of a single plate and is shaped and sized to be able to close the opening 303 of the outer container 3.
[0030] Figure 5 is a partially enlarged view of Figure 3. The details of the base 1 will be described below with reference to Figure 5. As shown in Figure 5, the main body 11 has a first member 13 and a second member 15 that are positioned to overlap each other. To further explain, the first member 13 is positioned to face the bottom wall 39 of the outer container 3 when attached to the outer container 3. The second member 15 is also positioned to be exposed to the outside when attached to the outer container 3. This second member 15 constitutes the bottom surface of the cosmetic container 100. Of these two members, the first member 13 is made of a relatively hard material, while the second member 15 is made of a material that is easily elastically deformable. In other words, the second member 15 is made of a material that is more elastically deformable than the first member 13.
[0031] In this embodiment, the first member 13 and the second member 15 are both formed to be substantially the same shape and dimensions. That is, the second member 15 is provided so as to cover the entire surface of one side of the first member 13, the side opposite to the side facing the bottom wall 39 of the outer container 3.
[0032] The first component 13 is molded from a resin material that is harder than the second component 15. Specifically, it is molded from a resin material selected from polypropylene resin (PP resin), acrylonitrile butadiene styrene resin (ABS resin), etc.
[0033] Furthermore, the second member 15 is molded from a softer material than the first member 13. Specifically, it is formed from an elastic material such as a thermoplastic elastomer, thermosetting elastomer, synthetic rubber, or silicone rubber.
[0034] The first member 13 and the second member 15 are integrally formed, and in this embodiment, they are formed by two-color molding. Two-color molding makes the bond between the first member 13 and the second member 15 stronger, making them less likely to separate. Note that the method for integrally forming the first member 13 and the second member 15 is not limited to two-color molding; other molding methods, such as insert molding, may also be used.
[0035] From the top surface 131 of the first member 13, a peripheral wall 17, formed in a substantially cylindrical shape, is provided along the peripheral edge of the first member 13, slightly inward from the surrounding area. The peripheral wall 17 is formed rising almost vertically from the top surface 131 of the first member 13, and is positioned so that when the bottom body 1 is attached to the outer container 3, the peripheral wall 17 is radially inward of the outer peripheral wall 311 of the outer container 3. In the illustrated example, the outer surface 171 of the peripheral wall 17 is formed to be in contact with the inner surface 315. In this way, the contact between the outer surface 171 of the peripheral wall 17 and the inner surface 315 of the outer peripheral wall 311 creates frictional resistance between them, and the bottom body 1 is fixed in a fitted state to the outer container 3. In other words, by inserting the peripheral wall 17 into the inner surface 315, the movement of the peripheral wall 17 within the inner surface 315 is restricted.
[0036] Furthermore, by ensuring that the outer surface 171 of the peripheral wall 17 is in contact with the inner surface 315 of the outer peripheral wall 311 of the outer container 3, that is, by inserting the peripheral wall 17 into the interior of the inner surface 315, it is possible to prevent water from entering the internal space of the outer container 3 through the gap between the bottom body 1 and the outer peripheral wall 311. In particular, when using the cosmetic container 100 in places with water, the risk of water ingress is eliminated.
[0037] In this embodiment, the peripheral wall 17 is provided with a tapered portion 173 on which a part of its outer surface 171 slopes inward toward the inner surface towards the tip. This tapered portion 173 facilitates the insertion of the peripheral wall 17 when attaching the bottom body 1 to the outer container 3.
[0038] The height of the peripheral wall 17 should be sufficient to secure the base body 1 in a fitted state relative to the outer container 3, without excessively hindering the attachment of the base body 1 to the outer container 3. Specifically, the ratio of the length of the base body 1 in the thickness direction to the length of the peripheral wall 17 in the height direction should be 1:2 to 1:5. In this embodiment, the peripheral wall 17 is provided on the first member 13, but it may be provided on the second member 15. Specifically, it may be provided so as to rise directly from the top surface of the second member 15, and the first member 13 may be formed to cover the area of the second member 15 other than the portion where the peripheral wall 17 is formed.
[0039] As a means of fixing the bottom body 1 to the outer container 3, the peripheral wall 17 may be forcibly fixed by inserting it into the outer peripheral wall 311 of the outer container 3. In addition to this fixing means, other fixing means may be used, for example, by using an adhesive such as a hot melt adhesive to bond the top surface 131 of the first member 13 and the bottom wall 39 of the outer container 3 together. Alternatively, these fixing means may be combined.
[0040] As shown in Figure 3, the main body 11, consisting of a first member 13 and a second member 15, is formed to be plate-like with substantially the same thickness, except for a portion in the center. In the central part of the main body 11, the second member 15 is formed to be thicker than the other parts and is formed to protrude toward the bottom wall 39 of the outer container 3. The first member 13, formed along this, also protrudes toward the outer container 3, forming a convex portion 137. This convex portion 137 is formed to substantially conform to the concave portion 391 provided on the bottom wall 39 of the outer container 3. The convex portion 137 makes it difficult for forces that cause horizontal displacement to occur between the first member 13 and the second member 15, thereby preventing them from separating. Furthermore, by positioning the convex portion 137 of the main body 11 within the concave portion 391 of the outer container 3, horizontal displacement between the main body 11 and the outer container 3 is suppressed.
[0041] Furthermore, as shown in Figure 5, the second member 15 is formed to a uniform thickness except for a portion. It also has a thin-walled portion 151, which is formed circumferentially along the periphery of the second member 15, resulting in a portion with a different thickness. This thin-walled portion 151 is positioned below the peripheral wall 17 of the first member 13. When the lid 7 is opened and closed while the cosmetic container 100 is placed on a table or the like, the bottom 1 is pressed against the outer peripheral wall 311 of the outer container 3. In the thin-walled portion 151, this downward stress is easily transmitted to the back side without being absorbed and dispersed by the elastic second member 15. As a result, pressure is applied to the bottom 1 from the center towards the periphery by the surface it is placed on, creating strong frictional resistance between the second member 15 and the surface it is placed on.
[0042] In this way, strong frictional resistance is generated between the base 1 and the mounting surface near the periphery rather than the center, which prevents rotational movement of the container body 200 that occurs when opening and closing the lid 7 or attaching and detaching the refill container 5 while the container is placed on a table or the like.
[0043] Furthermore, the inner circumference of the thin-walled portion 151 is provided with an inclined portion 155 that gradually increases in thickness towards the center of the second member 15. Because this inclined portion 155 is in contact with the inclined portion 133 of the first member 13, which will be described later, it becomes less likely for forces that cause horizontal displacement to occur between the first member 13 and the second member 15, thereby preventing them from separating.
[0044] Furthermore, a rising portion 157 is provided from the outer peripheral end of the thin-walled portion 151, such that the second member 15 rises up along the peripheral edge of the first member 13. The top surface 159 of this rising portion 157 and the top surface 131 of the first member 13 are formed to lie on the same plane. The top surface 159 of the rising portion 157 is formed to abut against the lower end portion 3111 on the bottom side of the outer peripheral wall 311 of the outer container 3. In this embodiment, the rising portion 157 is formed to be continuous in the circumferential direction along the peripheral edge of the first member 13.
[0045] In this way, the top surface 159 of the rising portion 157 and the lower end portion 3111 of the outer peripheral wall 311 of the outer container 3 come into contact, causing the stress applied in the direction of the bottom body 1 via the outer peripheral wall 311 when the lid 7 is opened and closed to act on the top surface 159 of the rising portion 157. This generates strong frictional resistance at the contact surface between the lower end portion 3111 and the top surface 159, preventing circumferential displacement of the bottom body 1 relative to the outer container 3.
[0046] Furthermore, the first member 13 is formed to a uniform thickness, except for a portion. It also has a thickened portion 139 formed circumferentially along its periphery, where the thickness differs. The thickened portion 139 is formed at a location that overlaps with the location where the thinned portion 151 of the second member 15 is formed. This thickened portion 139 improves the strength of the peripheral wall 17. It also prevents so-called sink marks from occurring during injection molding of the peripheral wall 17.
[0047] Furthermore, the inner circumference of the thickened portion 139 is provided with an inclined portion 133 such that the thickness gradually decreases toward the center of the first member 13. Because this inclined portion 133 is in contact with the inclined portion 155 of the second member 15, forces that cause horizontal displacement between the first member 13 and the second member 15 are less likely to occur, thereby preventing the two from separating.
[0048] In this embodiment, a projection 175 is formed on the outer surface 171 of the peripheral wall 17 so as to extend from the top surface 131 of the first member 13 to the tip side of the peripheral wall 17. When the bottom body 1 is attached to the outer container 3, this projection 175 is inserted into a vertical groove 319 formed on the inner surface 315 of the outer peripheral wall 311, thereby preventing the bottom body 1 from shifting in the circumferential direction relative to the outer container 3. Furthermore, these protrusions 175 allow for positioning when attaching the base body 1. There is no particular limit to the number of such protrusions 175, but when used for positioning, it is preferable to provide one or two.
[0049] The main body 11 of this embodiment is formed to have approximately the same dimensions as the outer peripheral wall 311 of the outer container 3, but a part of it protrudes outward from the outer peripheral wall 311 to form a protruding portion 19. The protruding portion 19 of this embodiment is provided by extending a part of the first member 13 and the second member 15 of the bottom body 1. The protruding portion 19 is provided with a spatula holding portion 191 that can hold a spatula 9 upright. The spatula holding portion 191 of this embodiment is formed as a roughly rectangular parallelepiped with an opening into which the end of the spatula 9 can be inserted. The spatula holding portion 191 is provided at the position furthest radially from the center of the bottom body 1. Therefore, the anti-slip effect of the second member 15 in the spatula holding portion 191 can effectively prevent slippage, especially in the rotational direction. In addition to the spatula holding part 191 of this embodiment, a holding means for directly attaching the spatula 9 to the outer container or lid by means of magnetism, for example, may also be used. Furthermore, the cosmetic applicator attached to the cosmetic container 100 may be something other than the spatula 9.
[0050] <Lid 7> As shown in Figure 3, the lid 7 of this embodiment has a female thread 73 formed on its inner surface into which the male thread 331 of the outer container 3 can be inserted. An O-ring 77 is provided on the back surface of the top wall 71 of the lid 7. A packing 75 is provided so as to sandwich the O-ring 77 between the top wall 71 and the packing 75.
[0051] <Method for opening and closing the lid 7> Next, the method for opening and closing the lid 7 of the cosmetic container 100 in this embodiment will be described. When opening and closing the lid 7 with one hand, the cosmetic container 100 can be placed on a table or the like, and the lid 7 can be opened and closed by operating it with one hand. When performing a rotational operation on the container body 200 to open or close the lid 7, it is preferable to apply force to the lid 7 in a downward direction. This causes the cosmetic container 100 itself to receive a force that presses it against the surface it is placed on, and the anti-slip effect of the second member 15 of the bottom body 1 prevents the container body 200 from rotating on the table or the like. As a result, the lid 7 can be easily opened and closed with just one hand. In addition, as with typical cosmetic containers, instead of placing the container on a table or other surface, the main body 31 of the outer container 3 can be held with one hand, or the container may be placed on a table or other surface and the main body 31 of the outer container 3 can be held with one hand while the lid 7 is rotated with the other hand to open and close it.
[0052] <How to replace refill container 5> As shown in Figures 3 and 6(a), when the refill container 5 is housed in the outer container 3, the outer periphery 57 is positioned so as to cover the thin wall portion 35. The protrusions 59 of the outer periphery 57 are inserted into the recesses 37 of the thin wall portion 35. Furthermore, the locking protrusions 573 of the outer periphery 57 lock onto the protruding ridges 353 of the outer container 3, thereby fixing the refill container 5 to the outer container 3. Then, from the state in which the refill container 5 is stored in the outer container 3, the refill container 5 can be removed by moving the refill container 5 and the outer container 3 relative to each other. In other words, the refill container 5 can be removed by moving the bottom wall 53 of the refill container 5 relative to the bottom wall 39 of the outer container 3 in a direction that separates them.
[0053] The method for removing the refill container 5 will be explained below with reference to Figures 6(a) to 6(c). Figure 6(a) shows the refill container 5 housed in the outer container 3. As shown in Figure 6(b), when the refill container 5 is rotated relative to the outer container 3 (see arrow F1 in the figure), the side portion 593 of the diagonally formed protrusion 59 slides against the side portion 373 of the similarly diagonally formed recess 37. As a result, the protrusion 59 moves in the direction of rotation and diagonally upward (see arrow F2 in the figure), and the refill container 5 also moves away from the outer container 3. In this way, the locking protrusion 573 of the outer periphery 57 can be released from its locking with the protrusion 353 of the thin wall portion 35. When the refill container 5 is rotated further relative to the outer container 3, the protrusion 59 becomes detached from the recess 37 (see Figure 6(c)), and the refill container 5 can be completely removed by pulling it out of the outer container 3.
[0054] In the removal operation of the refill container 5 described above, just as when opening and closing the lid 7, it is recommended to hold the protrusion 59 of the refill container 5 with your fingers and rotate it while lightly pressing the container body 200 against a surface such as a table. This causes the cosmetic container 100 itself to be pressed against the surface, and the anti-slip effect of the second member 15 of the base 1 prevents the container body 200 from rotating. As a result, the refill container 5 can be easily attached and detached with just one hand. Furthermore, as the refill container 5 rotates, the side portion 593 of the protrusion 59 moves along the side portion 373 of the recess 37, applying a downward pressing force to the container body 200. This improves the anti-slip effect and makes it easier to remove the refill container 5. In addition, as with typical cosmetic containers, instead of placing the container on a table, you may hold the main body 31 of the outer container 3 with one hand, or, while the container is on a table, you may hold the main body 31 of the outer container 3 with one hand and rotate the refill container 5 with the other hand to remove it. Alternatively, you may hold the main body 31 of the outer container 3 with one hand and pull the refill container 5 straight away without rotating it with the other hand to remove it.
[0055] <Example 1> Figure 7(a) shows Modification 1 of the base body 1 of the present invention. In Modification 1, the base body 1001 has a second member 15 provided in a limited area relative to the first member 13. Specifically, the second member 15 is provided only in an area along the outer edge of the first member 13. In this modification, since the first member 13 is formed in a circular shape, the second member 15 provided along its outer edge is formed in an annular shape.
[0056] In this way, when the second member 15 is provided in a limited area along the outer edge of the first member 13, the first member 13 surrounded by the second member 15 is exposed on the bottom side of the cosmetic container 100. The manufacturer can then affix a sticker or other label displaying information such as ingredient information to this portion of the first member 13. Furthermore, since the first member 13 is made of a hard material, the sticker is unlikely to peel off even if it is directly attached to it.
[0057] Furthermore, because a gap is created between the first member 13 and the surface on which it is placed, equal to the thickness of the second member 15 which is provided along the outer edge of the first member 13, the seal attached to the first member 13 does not come into contact with the surface on which it is placed. As a result, peeling or fading of the lettering due to contact between the surface on which the seal is placed is less likely to occur.
[0058] <Modification 2> Figure 7(b) shows a modified example 2 of the base 1 of the present invention. In the base 2001 of modified example 2, the second member 15 is provided in a limited area relative to the first member 13. Specifically, a plurality of circularly formed second members 15 are provided at predetermined intervals from each other. In this way, by providing multiple second members 15 on the first member 13, it is possible to prevent air from escaping between the smooth mounting surface and the second members 15, which would cause them to stick together. Here, the second members 15 may have a configuration other than circular. Also, they may be provided all around the first member 13 or in off-center positions.
[0059] <Variation 3> Figure 8 shows a third modification of the cosmetic container 100 of the present invention. In the cosmetic container 1100 of the third modification, a portion of the neck portion 33, where the male screw 331 is provided, has a protrusion 375 that protrudes upward so as to fit into the thin wall portion 35. In addition, the outer periphery 57 is provided with a recess 555 formed so as to be recessed toward the flange 55 from a portion of its lower edge 571. When the refill container 5 is housed in the outer container 3, the protrusion 375 is inserted into the recess 555.
[0060] When removing the refill container 5 in Modification 3, rotating the refill container 5 relative to the outer container 3 causes the side portion 377 of the protrusion 375 to slide against the side portion 557 of the similarly angled recess 555. As a result, the recess 555 moves diagonally upward so as to move over the protrusion 375 as the refill container 5 rotates, and the refill container 5 moves away from the outer container 3. In this way, the refill container 5 of Modification 3 can be easily removed.
[0061] <Modification 4> Figure 9 shows a modified example 4 of the cosmetic container 2100 of the present invention. In the cosmetic container 100 of modified example 4, the spatula holding portion 191 is not provided on the bottom body 1. In this way, the manufacturing cost can be reduced by not providing the spatula holder 191. Furthermore, the absence of the spatula holder 191 also gives the container a cleaner appearance. The general shape of the cosmetic container 100 of the present invention does not have to be approximately cylindrical. For example, it may be triangular prism, quadrangular prism, polygonal prism, or elliptical prism.
[0062] Furthermore, the cosmetic container of the present invention may not include a refill container 5. That is, the cosmetic may be filled directly into the outer container 3. Furthermore, the base 1 may include a third member made of a different material in addition to the first member 13 and the second member 15. For example, the third member may be sandwiched between the first member 13 and the second member 15 and laminated together.
[0063] The cosmetics to be stored in the cosmetic container of the present invention may include skincare cosmetics such as creams, lotions, serums, eye creams, lip balms, and removers; hair cosmetics such as treatments, hair styling products, hair dyes, and hair creams; and makeup cosmetics such as face powder, foundation, primer, concealer, blush, eye color, lip gloss, lip color, lip overcoat, topcoat, mascara, eyebrow pencil, and eyeliner. The dosage form may be a viscous liquid cosmetic, a powder-solid cosmetic, an oil-solid cosmetic, or a powder cosmetic, and may be an emulsion or a non-emulsified type.
[0064] Now, although various embodiments and modifications have been described above, these embodiments and modifications can of course be combined to form a complete system. Furthermore, this disclosure is not limited in any way to the embodiments described above, and can be implemented in various forms without departing from the gist of this disclosure.
