Summary of the Invention

Problems to be Solved by the Invention

[0004] The ice pack body and the lid member have a one-to-one set relationship, and only one type of lid member corresponding to the frame is attached to the frame attached to the opening of the ice pack body. Therefore, since the ice pack is unified as a single design as a whole, it has been necessary to replace the ice pack according to the mood, trend, or scene of use.

[0005] An object of the present invention is to provide an ice pack that can selectively replace lid bodies with different designs.

Means for Solving the Problems

[0006] The ice pack according to claim 1 comprises a bag-shaped body formed to gradually contract from the bottom to the top, a fixed base fixed to the periphery of the upper opening of the body and having an opening for inserting ice pieces, and a lid detachably attached to the fixed base and closing the opening, wherein the lid comprises a first lid having a three-dimensional decorative part and a second lid having a three-dimensional decorative part different from the first decorative part, and either the first lid or the second lid can be selectively attached to the fixed base.

[0007] According to the ice pack invention of claim 1, the main body and the fixing base are common parts, and the first lid and the second lid can be selectively attached to the fixing base according to the user's preference.

[0008] The ice pack according to claim 2 has a female thread on the inner circumferential surface of the opening, and the lid has a male thread on its outer circumferential surface that screws into the female thread, and comprises a shaft portion that is mounted in the opening, and a lid portion fixed to one end of the shaft portion that closes the opening when the shaft portion is mounted in the opening, and a first decorative portion may be provided on the upper surface of the lid portion of the first lid, and a second decorative portion may be provided on the upper surface of the lid portion of the second lid. As a result, the ice pack according to this embodiment can reliably close the opening of the fixed base.

[0009] The outer circumference of the lid of the ice pack according to claim 3 may be provided with one or more protrusions projecting radially outward. This allows the lid of the ice pack in this embodiment to be easily attached to and detached from the fixing base, as a finger can be placed on the protrusions provided on the outer circumference of the lid.

[0010] In a plan view of the lid of the ice pack according to claim 4, the first decorative part and the second decorative part may be positioned inward from the outer periphery of the lid. As a result, since both the first decorative part and the second decorative part are positioned inward from the outer periphery of the plate, the lid is easier to grasp.

[0011] The lid of the ice pack according to claim 5 comprises a plate portion and a peripheral wall projecting upward along the outer circumference of the plate portion, wherein the peripheral wall may surround the lower part of the first decorative portion or the second decorative portion. Since the peripheral wall surrounds the lower part of the first decorative portion or the second decorative portion, the connection portion between the plate portion and the first decorative portion, and the connection portion between the plate portion and the second decorative portion are covered by the peripheral wall. This prevents the user's fingers from touching these connection portions.

[0012] A hemispherical transparent cover covering the first decorative part or the second decorative part may be detachably attached to the lid of the ice pack according to claim 6. Since the first decorative part or the second decorative part is covered by the hemispherical transparent cover, it is possible to prevent the hands from touching the first decorative part and the second decorative part when gripping the first lid and the second lid.

[0013] The ice pack according to claim 7 is provided with a first projection on the upper surface of the lid that protrudes upward in a rod shape, and the bottom of the first decorative part and the second decorative part may be provided with a first hole that fits detachably with the first projection. This allows the first decorative part of the first lid to be replaced with the second decorative part, or the second decorative part of the second lid to be replaced with the first decorative part.

[0014] The ice pack according to claim 8 is provided with a second projection on the upper surface of the lid, which protrudes upward in a rod shape and has a male thread formed on its outer circumference, and the bottom of the first decorative part and the second decorative part are provided with a second hole, which has a female thread that engages with the male thread of the second projection. This allows the first decorative part of the first lid to be replaced with the second decorative part, or the second decorative part of the second lid to be replaced with the first decorative part.

Mode for Carrying Out the Invention

[0016] Hereinafter, embodiments of the present invention will be described. The configurations described below are not intended to be limited to only those, without specific description, but are merely illustrative examples. The drawings are used to explain the technical features that can be adopted by the present invention. The following description uses the directions indicated by the arrows in the drawings. Note that the orientation (direction) of the ice pack 1 defined in this embodiment is for convenience in explanation and is not necessarily limited.

[0017] The structure of the ice pack 1 will be described. As shown in FIGS. 1 and 2, the ice pack 1 includes a main body 2 and a first lid 5. The main body 2 is in a bag shape. Ice water is contained inside the main body 2. The first lid 5 is detachably attached to a fixing base 3 described later that is fixed to the upper part of the main body 2.

[0018] The structure of the main body 2 will be described. The main body 2 is formed in a bag shape from a flexible material. The side wall 2B of the main body 2 has a plurality of folds and gradually contracts while being twisted upward from the bottom 2A. A resin fixing base 3 is fixed to the peripheral edge of the opening at the upper part of the main body 2.

[0019] The fixing base 3 is in a short-axis substantially cylindrical shape that penetrates in the vertical direction. An opening 3A (see FIG. 2) is provided inside the fixing base 3. The opening 3A is an opening for inserting ice pieces. The fixing base 3 includes a base part 31 and a cylindrical part 32. The base part 31 is formed in a ring shape and is fixed to the peripheral edge of the opening at the upper part of the main body 2. The cylindrical part 32 is in a short-axis substantially cylindrical shape that extends upward from the upper part of the base part 31. The cylindrical part 32 has a larger diameter than the diameter of the base part 31. A female screw 32A is provided on the inner peripheral surface of the cylindrical part 32.

[0020] The structure of the first lid 5 will be described. As shown in FIG. 2, the first lid 5 is detachably attached to the opening 3A of the fixing base 3. The first lid 5 includes a lid part 6 and a first decorative part 10.

[0021] The lid part 6 includes a shaft part 7 and a dish part 8 and is an integrally molded resin product. The shaft part 7 is in a short-axis substantially cylindrical shape that extends in the vertical direction. The outer diameter of the shaft part 7 corresponds to the inner diameter of the cylindrical part 32 of the fixing base 3. A male screw 7A is provided on the outer peripheral surface of the shaft part 7. The male screw 7A is screwed with the female screw 32A inside the cylindrical part 32.

[0022] For example, the direction (R1 direction) of rotating the first lid 5 clockwise is the direction of tightening the male screw 7A to the female screw 32A. Conversely, the direction (R2 direction) of rotating the first lid 5 counterclockwise is the direction of loosening the male screw 7A with respect to the female screw 32A.

[0023] The disc portion 8 is provided perpendicular to the upper end of the shaft portion 7. The disc portion 8 comprises a plate portion 81, a peripheral wall 82, and two protrusions 9, 9.

[0024] The plate portion 81 is a disc and has an area that can close the opening 3A of the fixed base 3 from above. The upper end of the shaft portion 7 is connected perpendicularly to the center of the lower surface of the plate portion 81.

[0025] The peripheral wall 82 is provided along the outer periphery of the plate portion 81 and protrudes upward in a rib-like manner from the upper surface of the plate portion 81. The height of the peripheral wall 82 is such that, for example, when the dish portion 8 is viewed from the side, the connection between the upper surface of the plate portion 81 and the first decorative portion 10, which will be described later, is hidden. Therefore, the peripheral wall 82 surrounds the lower part of the first decorative portion 10.

[0026] The two protrusions 9, 9 are provided on the right and left sides of the outer periphery of the peripheral wall 82, facing each other. The protrusions 9 project radially outward from the outer periphery of the peripheral wall 82, and their outer surfaces are formed in a smooth, tapered shape without corners. The protrusions 9 extend in the circumferential direction and have one end 9A and the other end 9B. The one end 9A is the downstream end in the R1 direction, and the other end 9B is the upstream end in the R1 direction.

[0027] In the R1 direction, one end 9A rises gently from the outer circumference of the peripheral wall 82. In contrast, in the R2 direction, the other end 9B rises from the outer circumference of the peripheral wall 82 at a steeper angle than the one end 9A. When rotating the first lid 5 in the R1 direction to attach it to the fixing base 3, or rotating it in the R2 direction to remove it from the fixing base 3, the user hooks their fingers onto the protrusions 9,9 and rotates the first lid 5.

[0028] Since the other end 9B rises at a gentle angle, when you place your finger on the other end 9B and rotate the first cover 5 in the R1 direction to screw the male thread 7A into the female thread 32A, your finger will slide appropriately along the other end 9B. This prevents the male thread 7A from being overtightened against the female thread 32A.

[0029] On the other hand, since one end 9A rises at a steep angle, when you place your finger on one end 9A and rotate the first cover 5 in the R2 direction to loosen the male screw 7A against the female screw 32A, your finger will catch on one end 9A. As a result, even if the male screw 7A is tightly fastened against the female screw 32A, you can apply a strong force to one end 9A in the R2 direction.

[0030] The first decorative part 10 is a three-dimensional ornament made of resin, modeled after, for example, the head and face of a cartoon character. The first decorative part 10 comprises a face part 10A and a head part 10B. The head part 10B is a roughly spherical shape with no corners and occupies most of the first decorative part 10. Therefore, even if the hand strongly touches the head part 10B when the first lid 5 is grasped, its outer surface will not dig into the hand. The bottom of the first decorative part 10 is integrally fixed to the approximate center of the upper surface of the plate part 81 of the lid part 6 by means of adhesive or welding, for example.

[0031] Furthermore, although there are no specific requirements regarding the height of the first decorative part 10, as shown in Figure 3, it is preferable that the first decorative part 10 be positioned inward from the outer circumference of the dish part 8 when the first lid 5 is viewed in plan. This prevents the first decorative part 10 from interfering with the operation of the first lid 5 when the fingers are hooked onto the protrusions 9, 9.

[0032] The method of using the ice pack 1 will now be explained. As shown in Figure 4, the user first removes the first lid 5 from the fixing base 3 of the main body 2. Specifically, the user hooks their fingers onto the two protrusions 9,9 of the first lid 5 and rotates the first lid 5 in the R2 direction (see Figure 3). This allows the first lid 5 to be removed from the fixing base 3.

[0033] Here, the connection between the upper surface of the plate portion 81 of the first lid 5 and the bottom of the first decorative portion 10 is surrounded by a peripheral wall 82. This prevents the first decorative portion 10 from falling off when the user's hand touches the connection.

[0034] Next, the user places ice pieces and a small amount of water into the opening 3A, filling the main body 2 to about three-quarters of its capacity. Then, while removing the air, the first lid 5 is attached to the opening 3A of the fixing base 3. At this time, the first lid 5 is attached to the fixing base 3 by rotating it in the R1 direction relative to the fixing base 3. This completely seals the opening 3A of the fixing base 3 with the lid portion 6 of the first lid 5.

[0035] Then, press the bottom 2A of the main body 2 of the ice pack 1 against the affected area and cool it for, for example, 15 to 20 minutes. In addition to being used as a medical bag in this way, the ice pack 1 can also be used to cool the face, hands, and feet slowly as a measure against heatstroke. It can also be used as a substitute for a water bottle.

[0036] Incidentally, as shown in Figure 4, in this embodiment, the ice pack 1 can have a second lid 15 attached to the fixing base 3 of the main body 2 instead of the first lid 5 described above.

[0037] The structure of the second lid 15 will now be described. As shown in Figure 4, the second lid 15 is basically the same as the structure of the first lid 5, but differs in that it has a second decorative part 11 instead of the first decorative part 10. The second lid 15 comprises a lid part 16 and a second decorative part 11.

[0038] The lid portion 16 comprises a shaft portion 17 and a dish portion 18, and is a single molded resin product. The shaft portion 17 is a roughly cylindrical shape with a short axis extending in the vertical direction. The outer diameter of the shaft portion 17 corresponds to the inner diameter of the cylindrical portion 32 of the fixed base 3. A male thread 17A is provided on the outer circumferential surface of the shaft portion 17. The male thread 17A is screwed into the female thread 32A on the inside of the cylindrical portion 32.

[0039] The dish portion 18, like the dish portion 8 of the first lid 5, comprises a plate portion (not shown), a peripheral wall 182, and two protrusions 19, 19.

[0040] The second decorative part 11 is made of resin and is a three-dimensional ornament, but its design is completely different from that of the first decorative part 10, and is modeled after the shape of a volleyball, for example. The bottom of this second decorative part 11 is integrally fixed to the approximate center of the upper surface of the plate portion of the lid 16 by means of adhesive or welding, for example. Since a volleyball is a spherical shape with no corners, even if the hand strongly touches the second decorative part 11 when grasping the second lid 15, its outer surface will not dig into the hand.

[0041] Furthermore, although there are no specific height requirements for the second decorative part 11, it is preferable that, similar to the first decorative part 10, the second decorative part 11 be positioned inward from the outer circumference of the dish portion 18 when the second lid 15 is viewed in plan. This prevents the second decorative part 11 from interfering with the operation of the second lid 15 when the fingers are hooked onto the protrusions 19, 19.

[0042] As shown in Figure 5, this second cover 15 can be attached to the fixing base 3 of the main body 2 in place of the first cover 5. The method for attaching and detaching the second cover 15 to the fixing base 3 is exactly the same as the method for attaching and detaching the first cover 5 described above.

[0043] As shown in Figures 1 and 5, the appearance and impression of the ice pack 1 with the first lid 5 attached to the main body 2 is significantly different from that of the ice pack 1 with the second lid 15 attached to the main body 2. This allows the user to appropriately select and attach the lid to the main body 2 depending on the situation and mood in which they will be using the ice pack 1. Thus, the design of the ice pack 1 can be changed to suit various situations. Since there is no need to purchase multiple ice packs with different designs, the cost of the ice pack 1 can be reduced compared to conventional ice packs.

[0044] As described above, the ice pack 1 of this embodiment comprises a main body 2, a fixing base 3, a first lid 5, and a second lid 15. The main body 2 is bag-shaped and is formed to gradually contract from the bottom 2A towards the top. The fixing base 3 is fixed to the periphery of the opening at the top of the main body 2 and has an opening 3A for inserting ice pieces.

[0045] The first lid 5 has a first decorative part 10. The first decorative part 10 has a three-dimensional shape. The second lid 15 has a second decorative part 11. The second decorative part 11 has a different three-dimensional shape from the first decorative part 10.

[0046] Furthermore, either the first lid 5 or the second lid 15 can be selectively attached to the fixing base 3 of the main body 2. This allows the ice pack 1 to use the main body 2 and the fixing base 3 as common parts, and to selectively attach either the first lid 5 or the second lid 15 to the fixing base 3 depending on the user's preference or the situation in which it will be used.

[0047] It should be noted that this invention is not limited to the above-described embodiment, and various modifications are possible. Five modified examples are described below.

[0048] Referring to Figures 6 and 7, the first modified example will be described. In the above embodiment, either the first cover 5 or the second cover 15 can be selectively attached to the fixing base 3 of the main body 2, but a third cover 25 may also be attached. The third cover 25 is a modified version of the first cover 5 and the second cover 15.

[0049] The structure of the third lid 25 is basically the same as that of the first lid 5, but it differs in that it has a third decorative part 12 instead of the first decorative part 10, and also has a transparent cover 40. The third lid 25 comprises a lid part 26, a third decorative part 12, and a transparent cover 40.

[0050] The lid portion 26 comprises a shaft portion 27 and a dish portion 28, and is a single molded resin product. The shaft portion 27 is a roughly cylindrical shape with a short axis extending in the vertical direction. The outer diameter of the shaft portion 27 corresponds to the inner diameter of the cylindrical portion 32 of the fixed base 3. A male thread (not shown) is provided on the outer circumferential surface of the shaft portion 27. The male thread engages with the female thread 32A on the inside of the cylindrical portion 32.

[0051] The dish portion 28, like the dish portion 8 of the first lid 5, comprises a plate portion 281, a peripheral wall 282, and two protrusions 29, 29.

[0052] The third decorative part 12 is made of resin and is a three-dimensional ornament, but its design is completely different from that of the first decorative part 10 and the second decorative part 11, and is, for example, modeled after the shape of a piano. This third decorative part 12 is integrally fixed to the approximate center of the upper surface of the plate part 281 of the lid part 26 by adhesive or welding.

[0053] Furthermore, although there are no specific height requirements for the third decorative part 12, similar to the first decorative part 10, it is preferable that the third decorative part 12 be positioned inward from the outer circumference of the dish part 28 when the third lid 25 is viewed in plan. This prevents the third decorative part 12 from interfering with the operation of the third lid 25 when hooking fingers onto the protrusions 29, 29.

[0054] However, since the third decorative part 12 is a decoration for the piano, unlike the first decorative part 10 and the second decorative part 11, it has multiple corners. Therefore, if you touch the third decorative part 12 directly, there is a possibility that your hand will come into contact with one of the corners. Also, due to the shape of the piano, foreign objects such as strings or clothing are likely to get caught on the corners. For this reason, in this embodiment, the third decorative part 12 is covered with a transparent cover 40 to prevent direct contact with the third decorative part 12.

[0055] As shown in Figures 6 and 7, the transparent cover 40 is made of transparent resin and has a roughly hemispherical dome shape, and is attached to the lid portion 26 so as to cover the third decorative portion 12. The lower end portion 40A of the transparent cover 40 is roughly circular in shape when viewed from the bottom. Six engaging claws 41 are provided on the lower end portion 40A at equal intervals in the circumferential direction. The engaging claws 41 protrude downward from the lower end portion 40A.

[0056] In contrast, six engagement holes 285 are provided at equal intervals in the circumferential direction on the outer periphery of the upper surface of the plate portion 281. Each of the six engagement holes 285 corresponds to each of the six engagement claws 41. Each of the six engagement claws 41 is detachably engaged with each of the six engagement holes 285. Thus, the transparent cover 40 is detachably attached to the upper surface of the plate portion 281.

[0057] As shown in Figure 6, when the third cover 25 is attached to the fixing base 3 of the main body 2, the appearance and impression it gives are significantly different compared to when the first cover 5 or the second cover 15 is attached.

[0058] Furthermore, since the area around the third decorative part 12 is covered by the transparent cover 40, it is possible to prevent the hand from directly touching the third decorative part 12 when gripping the third lid 25. This prevents foreign objects such as strings or clothing from getting caught on the corners of the third decorative part 12.

[0059] A second modified example will be described with reference to Figures 8 and 9. In the first lid 5 of the above embodiment, the first decorative part 10 is fixed to the upper surface of the plate portion 81 of the lid portion 6 and integrally formed (see Figure 4). In contrast to this configuration, the first decorative part 10 may be detachably attached to the upper surface of the plate portion 81.

[0060] The fourth cover 35 shown in Figure 8 is also a modified version of the first cover 5 and second cover 15 of the above embodiment. The fourth cover 35 is equipped with a cover portion 60, and either the fourth decorative portion 70 or the fifth decorative portion 90 can be selectively attached to or detached from the cover portion 60.

[0061] The lid portion 60 comprises a shaft portion 67 and a dish portion 68, and is a single molded resin product. The shaft portion 67 is a roughly cylindrical shape with a short axis extending in the vertical direction. The outer diameter of the shaft portion 67 corresponds to the inner diameter of the cylindrical portion 32 of the fixed base 3. A male thread 67A is provided on the outer circumferential surface of the shaft portion 67. The male thread 67A is screwed into the female thread 32A on the inside of the cylindrical portion 32.

[0062] The dish portion 68 comprises a plate portion 681, a peripheral wall 682, and two protrusions 69, 69. The plate portion 681 has a base portion 61 at the center of the upper surface of the disc. The base portion 61 is a roughly cylindrical shape with a short axis that protrudes upward. Furthermore, a projection 62 is provided at the center of the upper surface of the base portion 61. The projection 62 is a round rod that protrudes upward. The tip of the projection 62 is formed in a tapered shape without corners.

[0063] The fourth decorative part 70 is modeled after, for example, the same cartoon character as the first decorative part 10, and comprises a face part 70A and a head part 70B. A fixing hole 71 is provided at the bottom of the face part 70A. The fixing hole 71 extends upward.

[0064] The fifth decorative part 90 is modeled after a volleyball, just like the second decorative part 11. A fixing hole 91 is provided at the bottom of the fifth decorative part 90. The fixing hole 91 extends upward.

[0065] For example, when attaching the fourth decorative part 70 to the lid part 60, the fixing hole 71 of the fourth decorative part 70 is fitted into the projection 62 of the plate part 681 from above until it is fully inserted. At this time, it is fitted until the bottom of the face part 70A contacts the upper surface of the base part 61 (see Figure 9). This securely fixes the fourth decorative part 70 to the dish part 68. In this way, the fourth lid 35 equipped with the fourth decorative part 70 is constructed.

[0066] On the other hand, when attaching the fifth decorative part 90 to the lid part 60, the fixing hole 91 of the fifth decorative part 90 is fitted into the projection 62 of the plate part 681 from above until it is fully inserted. At this time, the bottom of the fifth decorative part 90 is fitted until it contacts the upper surface of the base part 61. This securely fixes the fifth decorative part 90 to the dish part 68, and a lid body equipped with the fifth decorative part 90 is formed.

[0067] Thus, in the second modified example, not only the main body 2 and the fixing base 3 of the above embodiment, but also the lid 60 can be used as common parts. Furthermore, depending on the user's mood or the situation in which it is used, either the fourth decorative part 70 or the fifth decorative part 90 can be selectively fixed to the lid 60.

[0068] In the description of the second modified example above, the base portion 61 and the projection 62 are examples of the "first projection" of the present invention. The fixing hole 71 of the fourth decorative portion 70 and the fixing hole 91 of the fifth decorative portion 90 are examples of the "first fixing hole" of the present invention.

[0069] Referring to Figure 10, the third modified example will be described. Since the third modified example is a further modification of the second modified example, only the differences from the second modified example will be described. The lid portion 160 is basically the same as the lid portion 60 of the second modified example, but a male thread 62A is formed on the outer circumferential surface of the projection 62. Parts common to the lid portion 60 will be denoted by the same reference numerals and described accordingly.

[0070] The sixth decorative section 170 has basically the same structure as the fourth decorative section 70. The seventh decorative section 190 has basically the same structure as the fifth decorative section 90.

[0071] A female thread 71A is formed on the inner circumferential surface of the fixing hole 71 of the sixth decorative part 170. The male thread 62A of the projection 62 can be screwed into the female thread 71A. Also, a female thread 91A is formed on the inner circumferential surface of the fixing hole 91 of the seventh decorative part 190. The male thread 62A of the projection 62 can also be screwed into the female thread 91A.

[0072] In this configuration, the female thread 71A of the fixing hole 71 of the sixth decorative part 170 is screwed all the way into the male thread 62A of the projection 62 of the plate portion 681 of the lid portion 160, and the bottom of the face portion 70A is brought into contact with the upper surface of the base portion 61. As a result, the sixth decorative part 170 is stably fixed to the lid portion 160, and the lid body with the sixth decorative part 170 is formed as a single unit.

[0073] On the other hand, the female thread 91A of the fixing hole 91 of the seventh decorative part 190 is screwed all the way into the male thread 62A of the projection 62 of the plate portion 681 of the lid portion 160, and the bottom of the seventh decorative part 190 is brought into contact with the upper surface of the base portion 61. As a result, the seventh decorative part 190 is stably fixed to the lid portion 160, and the lid body with the seventh decorative part 190 is formed as a single unit.

[0074] Thus, in this third modification as well, not only the main body 2 and the fixing base 3, but also the lid 160 can be used as a common part. Furthermore, depending on the user's mood or the situation in which it will be used, either the sixth decorative part 170 or the seventh decorative part 190 can be selected and fixed to the lid 160.

[0075] Furthermore, in the third modified example, the male screw 62A is fixed by screwing it into the female screw 71A, and the male screw 62A is fixed into the female screw 81A, so the sixth decorative part 170 or the seventh decorative part 190 can be fixed more firmly to the lid part 160 than in the second modified example.

[0076] In the second and third modified examples, the base portion 61 may be omitted. Also, although the base portion 61 is cylindrical, it may also be rectangular. Furthermore, by matching the height of the base portion 61 to the height of the surrounding wall 682, the fourth decorative portion 70 and the fifth decorative portion 90 (see Figure 8), and the sixth decorative portion 170 and the seventh decorative portion 190 (see Figure 10), which are fixed to the projection 62, can be easily seen from the surroundings.

[0077] In the description of the third modified example above, the base portion 61 and the projection 62 are examples of the "second projection" of the present invention. The fixing hole 71 of the sixth decorative portion 170 and the fixing hole 91 of the seventh decorative portion 190 are examples of the "second fixing hole" of the present invention.

[0078] Referring to Figures 11 and 12, the fourth and fifth modifications will be described. The fourth and fifth modifications involve changing the shape and number of the protrusions 9, 9 on the lid portion 6 of the first lid 5 of the above embodiment.

[0079] As shown in Figure 11, the lid portion 56 of the fifth lid 150 is provided with a dish portion 58. The dish portion 58 comprises a plate portion 581 and a peripheral wall 582. Multiple protrusions 59 are continuously provided in the circumferential direction on the outer periphery of the peripheral wall 582, projecting radially outward in a curved shape when viewed from above.

[0080] As shown in Figure 12, the lid portion 66 of the sixth lid 250 is provided with a dish portion 68. The dish portion 68 comprises a plate portion 681 and a peripheral wall 682. Multiple protrusions 69 are provided continuously in the circumferential direction on the outer periphery of the peripheral wall 682, projecting in a substantially trapezoidal shape radially outward in a plan view.

[0081] In these fifth lids 150 and sixth lids 250 as well, the user can hook their fingers onto the multiple protrusions 59 and 69 provided on the outer circumference of the lid portions 56 and 66. Therefore, the user can easily rotate the fifth lid 150 and sixth lids 250, similar to the above embodiment.

[0082] Furthermore, the shape and number of the protrusions 9 can be changed in various ways, not limited to the fourth and fifth modified examples. For example, there may be one protrusion 9, or two or more. Also, the protrusions 9 may be omitted.

[0083] Other variations will be described. In the above embodiment, the first decorative part 10, the second decorative part 11, the third decorative part 12, the fourth decorative part 70, the fifth decorative part 90, etc. were described as examples of decorative parts, but other three-dimensional shapes are also possible. For example, a decorative part may have a decorative plate that stands upright in the vertical direction, and cartoon characters or patterns, etc., may be printed on the decorative plate.

[0084] In the above embodiment, a female thread 32A is formed in the opening 3A of the fixed base 3, and the male thread 7A of the lid 6 is screwed into the female thread 32A. However, other fixing methods are also possible. For example, the fixed base 3 may be provided with a plurality of engagement holes, and the lid 6 may be provided with a plurality of engagement parts that can engage with these engagement holes, thereby allowing the lid 6 to be attached to and detached from the fixed base 3.
