FIG. 17 is a schematic four-sided view showing a cover 1 for a cup-shaped container in a third modified example of the first embodiment. In FIG. 17, a schematic plan view is shown in the upper left side, a schematic side view is shown in the upper right side, a schematic front view is shown in the center of FIG. 17, and a schematic bottom view is shown in the lower part of FIG. 17. FIG. 18 is a cross-sectional view taken along the line AA in FIG. 17. FIG. 19 is a schematic cross-sectional view showing a cover 1 for a cup-shaped container in a fourth modified example of the first embodiment. FIG. 20 is a schematic cross-sectional view showing a lid 1 for a cup-shaped container in a fifth modified example of the first embodiment.

[0020] As illustrated in FIG. 1, a lid 1 for a cup-shaped container in the first embodiment has a skirt 2 and a top plate 3.

[0021] The skirt 2 is attached to a side wall 91 of a cup-shaped container 9 capable of containing food or drink D1.

[0022] The top plate 3 has a top surface 31a and a bottom surface 31b. The top plate 3 also has an outer edge portion 32 that is continuous with the skirt 2, and a central portion 35 that closes the opening OP of the cup-shaped container 9.

[0023] The central portion 35 has a tip 36 and a tapered surface TP. The tapered surface TP is configured so that, when steam is generated from food or drink D1 contained in the cup-shaped container 9, water droplets D2 originating from the steam are collected at the tip 36 (see FIG. 2). The water droplets D2 collected at the tip 36 become drops D3 and fall toward the food or drink D1 or the bottom wall 93 of the cup-shaped container 9 (see FIG. 2).

[0024] 3, the lid 1' in the comparative example does not have a pointed tip or a tapered surface. When the lid 1' is removed from the cup-shaped container 9, the water droplets on the lid 1' turn into drops D3' and fall onto the desk DK or the like. In this case, the user needs to wipe the desk or the like with tissue or a cloth.

[0025] In contrast, in the lid 1 for a cup-shaped container in the first embodiment, the water droplets D2 adhering to the lid 1 easily return to the cup-shaped container 9 via the tapered surface TP and the cusp 36. Therefore, as illustrated in Fig. 4, the water droplets D2 adhering to the lid 1 are unlikely to turn into drops and fall onto the desk DK or the like.

[0026] In the example shown in Fig. 2, hot food or drink D1 is contained in the cup-shaped container 9. It goes without saying that cold food or drink may also be contained in the cup-shaped container 9. In this case, steam is not generated from the food or drink, and water droplets do not adhere to the lid 1. Therefore, in this case, drops do not fall from the lid 1 onto the desk DK or the like.

[0027] (Optional configuration) Next, optional additional configurations that can be adopted in the lid 1 for a cup-shaped container in the first embodiment will be described with reference to Figs.

[0028] (Skirt 2) 2, the skirt 2 is configured to be attached to an inner surface 91n of a side wall 91 of the cup-shaped container 9. More specifically, the skirt 2 is configured to fit into the inner surface 91n of the side wall 91 of the cup-shaped container 9. The top plate 3 also has a first bottom surface 35b that defines the tapered surface TP, and a second bottom surface 32b that abuts against a top surface 91u of the side wall 91.

[0029] 2, the skirt 2 is disposed between the first bottom surface 35b on which the tapered surface TP is provided and the second bottom surface 32b. Therefore, the skirt 2 prevents or inhibits the water droplets D2 adhering to the first bottom surface 35b from moving to the second bottom surface 32b.

[0030] (Slot SL) Assume that the lid body 1 is to be washed. In the example shown in FIG. 5, when the lid body 1 is turned over after being washed, the cleaning liquid W accumulates on the inside of the skirt 2. In this case, the inside of the skirt 2 is difficult to dry. Therefore, the lid body 1 cannot be quickly reused.

[0031] Therefore, in the example shown in Fig. 6, a slot SL is formed in the skirt 2. More specifically, as shown in Fig. 7, the skirt 2 has a plurality of skirt walls (21a, 21b, 21c). In addition, a slot SL is formed between two adjacent skirt walls 21.

[0032] The slots SL function as drainage slots. In the example shown in Fig. 6, the cleaning liquid inside the skirt 2 is quickly drained to the outside of the skirt 2 through the slots SL (see the dashed arrows in Fig. 6). Therefore, the inside of the skirt 2 is quickly dried, and the lid 1 can be quickly reused.

[0033] (Multiple Ribs LB) In the example shown in FIG. 7, the skirt 2 (more specifically, each of the multiple skirt walls 21) has multiple ribs LB that abut against the inner surface 91n of the side wall 91 of the cup-shaped container 9. It is preferable that two or more ribs LB are arranged on each skirt wall 21. In this specification, the direction from the top surface of the top plate 3 toward the bottom surface of the top plate 3 is defined as a first direction DR1. In the example shown in FIG. 7, each rib LB extends along the first direction DR1.

[0034] As illustrated in FIG. 8, when the multiple ribs LB come into contact with the inner surface 91n of the side wall 91, the skirt 2 (more specifically, each of the multiple skirt walls 21) is configured to elastically deform inward (see the dashed arrow in FIG. 8). In the example illustrated in FIG. 8, the slot SL has a function of promoting the inward elastic deformation of the skirt 2 (more specifically, each of the multiple skirt walls 21). In the example illustrated in FIG. 8, the multiple ribs LB and the force of the elastically deformed skirt 2 to return to its original shape allow the skirt 2 to be firmly fitted to the inner surface 91n of the side wall 91 of the cup-shaped container 9. Therefore, the lid 1 is unlikely to come off from the cup-shaped container 9.

[0035] As illustrated in Fig. 8, when the skirt 2 is attached to the side wall 91 of the cup-shaped container 9, a minute space SP exists between the inner surface 91n of the side wall 91 of the cup-shaped container 9, the outer surface 2t of the skirt 2, and two adjacent ribs LB. The minute space SP allows steam generated from food and drink in the cup-shaped container 9 to pass through. Therefore, when the skirt 2 is attached to the side wall 91 of the cup-shaped container 9, the internal pressure of the cup-shaped container 9 is prevented from increasing excessively. As a result, the lid 1 is prevented from coming off the cup-shaped container 9 with force due to an increase in internal pressure.

[0036] Furthermore, in a state where the skirt 2 is attached to the side wall 91 of the cup-shaped container 9, the minute space SP allows air to communicate between the internal space of the cup-shaped container 9 and the outside of the cup-shaped container 9. Therefore, the internal pressure of the cup-shaped container 9 does not drop excessively due to the food or drink in the cup-shaped container 9 cooling down. In addition, the lid 1 does not become unable to be removed from the cup-shaped container 9 due to an excessive drop in the internal pressure of the cup-shaped container 9.

[0037] In the example shown in Fig. 8, the lid body 1 is not provided with a packing. Therefore, the communication of air between the internal space of the cup-shaped container 9 and the outside of the cup-shaped container 9 is not hindered by the packing. In the example shown in Fig. 8, even when the lid body 1 is completely attached to the cup-shaped container 9, the cup-shaped container 9 is not completely sealed by the lid body 1. In other words, even when the lid body 1 is completely attached to the cup-shaped container 9, if the cup-shaped container 9 and the lid body 1 are turned upside down, the liquid in the cup-shaped container 9 will seep out from between the cup-shaped container 9 and the lid body 1.

[0038] In the example shown in FIG. 8, the lid 1 functions as a stopper for the cup-shaped container 9. In this specification, the stopper refers to an internally fitted lid that fits inside the opening of the container. In the example shown in FIG. 8, the lid 1 is not provided with a screw. In the example shown in FIG. 8, the lid 1 can be attached to the cup-shaped container 9 with a single touch by simply pushing the lid 1 into the cup-shaped container 9.

[0039] (Ring Wall 23) As illustrated in Fig. 9, it is assumed that the inverted lid 1 is placed on a placement surface such as a desk DK. In this case, water droplets D2 attached to the lid 1 flow along the tapered surface TP and tend to flow onto the placement surface through the slots SL. Also, as illustrated in Fig. 10, when the lid 1 is removed from the cup-shaped container 9, the water droplets D2 attached to the lid 1 tend to fall downward through the slots SL.

[0040] Therefore, in the example shown in Fig. 11, the skirt 2 has a ring wall 23. The ring wall 23 connects the top plate 3 and the multiple skirt walls 21. As shown in Fig. 12, the ring wall 23 functions as a bank that prevents water droplets D2 from flowing out from the inside of the skirt 2 to the placement surface when the inverted lid body 1 is placed on the placement surface. Also, as shown in Fig. 13, the ring wall 23 prevents or suppresses the water droplets D2 from falling downward through the slot SL when the lid body 1 is removed from the cup-shaped container 9.

[0041] (Shape and size of each part of the lid 1) In the example shown in Figures 4, 7, and 11, the central portion 35 of the tabletop 3 has a pyramid 37. The pyramid 37 protrudes further in the first direction DR1 than the outer edge portion 32 of the tabletop 3. In the example shown in Figures 4, 7, and 11, the pyramid 37 is a circular cone 370. Alternatively, the pyramid 37 may be a pyramid. The side surface of the pyramid 37 (e.g., the circular cone 370) defines the tapered surface TP described above, and the apex of the pyramid 37 (e.g., the circular cone 370) is the cusp 36 described above.

[0042] 6 and 9, the cone 37 (for example, the cone 370) is solid. When the cone 37 is solid, the strength of the cone 37 is high. The cone 37 is, for example, a rigid body.

[0043] 14, the pyramid 37 is a multi-stage pyramid. More specifically, the pyramid 37 has a first portion 371 connected to the outer edge portion 32 of the tabletop 3 and a second portion 372 connected to an inner edge portion 371n of the first portion 371.

[0044] 14, the tapered surface TP (more specifically, the first portion 371 of the pyramid 37) is connected to the outer edge portion 32 of the table top 3 and includes a first tapered surface TP1 that faces in the first direction DR1 toward the center of the table top 3. The tapered surface TP (more specifically, the second portion 372 of the pyramid 37) is connected to the inner edge of the first tapered surface TP1 and includes a second tapered surface TP2 that faces in the first direction DR1 toward the center of the table top 3.

[0045] In the example shown in FIG. 14, the inclination angle α1 of the first tapered surface TP1 with respect to the plane PL perpendicular to the central axis AX1 of the tabletop 3 is larger than the inclination angle α2 of the second tapered surface TP2 with respect to the plane PL perpendicular to the central axis AX1 of the tabletop 3.

[0046] 14, the angle α2 between the tapered surface TP (the second tapered surface TP2 in the example shown in FIG. 15) forming the cusp 36 and the plane PL perpendicular to the central axis AX1 of the tabletop 3 is preferably 1 degree or more and 30 degrees or less. The angle α2 is more preferably 3 degrees or more and 20 degrees or less, and even more preferably 5 degrees or more and 15 degrees or less.

[0047] When the angle α2 is sufficiently large, the water droplets D2 adhering to the tapered surface TP are effectively collected at the peak 36. Furthermore, when the angle α2 is 30 degrees or less (more preferably, 20 degrees or less, or 15 degrees or less), the amount of protrusion of the peak 36 from the outer edge portion 32 of the tabletop 3 in the first direction DR1 does not become excessive.

[0048] 14, the inclination angle α1 is about 30 degrees. The inclination angle α1 is 5 degrees or more and 45 degrees or less, 15 degrees or more and 40 degrees or less, or 25 degrees or more and 35 degrees or less. The large inclination angle α1 allows the groove V1 described below to be formed appropriately.

[0049] 15, the amount of protrusion of the peak 36 in the first direction DR1 from the outer edge portion 32 of the table top 3 (more specifically, the base of the skirt 2) is defined as a first protrusion amount AM1. Also, the amount of protrusion of the skirt 2 in the first direction DR1 from the outer edge portion 32 of the table top 3 (more specifically, the base of the skirt 2) is defined as a second protrusion amount AM2. In the example shown in FIG. 15, the first protrusion amount AM1 is smaller than the second protrusion amount AM2.

[0050] In the example shown in Fig. 15, the second protrusion amount AM2 is 8 mm. The second protrusion amount AM2 is preferably set to a size that prevents the skirt 2 from unintentionally coming off the cup-shaped container 9. The second protrusion amount AM2 is preferably set to, for example, 5 mm to 20 mm, 6 mm to 15 mm, or 7 mm to 10 mm. The first protrusion amount AM1 is, for example, 2 mm to 15 mm, 3 mm to 12 mm, or 4 mm to 8 mm.

[0051] In the example shown in FIG. 15, an annular groove V1 is formed by the inner circumferential surface 23n of the ring wall 23, the tapered surface TP, and the annular surface 24 connecting the inner circumferential surface 23n and the tapered surface TP. When the lid body 1 is in an inverted state, a small amount of water droplets D2 can be stored in the groove V1 (see FIG. 12). The depth of the groove V1 is set to an appropriate depth. Since the depth of the groove V1 is not too small, the amount of water that can be stored in the groove V1 is not too small. Furthermore, since the depth of the groove V1 is not too large, the time required for drying the groove V1 is not too long.

[0052] As illustrated in Fig. 15, the height of the ring wall 23 in the direction along the central axis AX1 of the top plate 3 is defined as a first height H1. In the example illustrated in Fig. 15, the first height H1 is 2 mm. It is preferable that the first height H1 is set to, for example, 1 mm or more and 4 mm or less, 1.5 mm or more and 4 mm or less, or 2 mm or more and 4 mm or less. In addition, it is preferable that the first height H1 is smaller than the above-mentioned first protrusion amount AM1.

[0053] 14 , the skirt 2 includes five skirt walls 21. Also, five slots SL are formed in the skirt 2. When the number of skirt walls 21 included in the skirt 2 is defined as "K" (or when the number of slots SL provided in the skirt 2 is defined as "K"), "K" is, for example, 2, 3, 4, 5, 6, 7, 8, 9, or 10.

[0054] The multiple skirt walls 21 are preferably arranged along a circle centered on the central axis AX1 of the top board 3.

[0055] In the example shown in Fig. 13, the skirt 2 of the lid 1 is only a skirt that contacts the inner surface 91n of the side wall 91 of the cup-shaped container 9, and the lid 1 is not provided with a skirt that contacts the outer surface 91t of the side wall 91 of the cup-shaped container 9. When two skirts are provided to sandwich the side wall 91 of the cup-shaped container 9, it is difficult to clean the area between the two skirts. In contrast, in the example shown in Fig. 13, since no other skirt is provided opposite the skirt 2, it is easy to clean the entire skirt 2.

[0056] In the example shown in Fig. 16, the top plate 3 is not formed with a hole for a straw or the like. As exemplified in Fig. 16, the outer diameter of the top plate 3 is defined as outer diameter L1. In the example shown in Fig. 16, the outer diameter L1 is 72 mm. The outer diameter L1 is set to, for example, 60 mm or more and 100 mm or less, or 60 mm or more and 80 mm or less.

[0057] 16, the area of ​​the tapered surface TP when viewed in a direction along the central axis AX1 of the tabletop 3 (i.e., the area of ​​the projected portion formed by projecting the tapered surface TP onto a plane perpendicular to the central axis AX1 in a direction along the central axis AX1 of the tabletop 3) is defined as a first area ME1. In FIG. 16, the first area ME1 is the area of ​​the portion indicated by hatching with dots.

[0058] As illustrated in Fig. 16, the area of ​​the closed region defined by the inner edge of the skirt 2 when viewed in a direction along the central axis AX1 of the tabletop 3 (i.e., the area of ​​the projected portion formed by projecting the closed region onto a plane perpendicular to the central axis AX1 of the tabletop 3 in a direction along the central axis AX1) is defined as the second area ME2. In Fig. 16, the second area ME2 is the area of ​​the portion indicated by hatching with diagonal lines.

[0059] 16, the first area ME1 is 0.89 times the second area ME2. Because the ratio of the first area ME1 to the second area ME2 is sufficiently large, most of the water droplets D2 adhering to the top plate 3 are collected at the cusp 36 by the tapered surface TP. The first area ME1 (the area of ​​the portion hatched with dots) is 0.5 to 1 times the second area ME2 (the area of ​​the portion hatched with diagonal lines), more preferably 0.6 to 1 times, and even more preferably 0.7 to 1 times.

[0060] In the example shown in FIG. 2, the top surface 31a of the tabletop 3 is a flat surface without a recess. Alternatively, as shown in FIG. 17 and FIG. 18, the top surface 31a of the tabletop 3 may have a recess 311a. As shown in FIG. 17 and FIG. 18, the recess 311a may have a letter or a pattern DS protruding therefrom. When the letter or pattern DS protrudes from the recess 311a, the letter or pattern DS is less likely to deteriorate due to abrasion or the like. In the example shown in FIG. 18, the letter or pattern DS is formed on the upper surface of the pyramid 37. The pyramid 37 is thicker than other parts (for example, the outer edge part 32 of the lid 1). Therefore, the pyramid 37 can stably support the part on which the letter or pattern DS protrudes.

[0061] In the example shown in Fig. 17, the cusp 36 is located on the central axis AX1 of the cover 1. Alternatively, the cusp 36 may be located at a position slightly offset from the central axis AX1 of the cover 1. In the example shown in Fig. 17, the cusp 36 is configured to be visible through the slot SL when viewed in a direction perpendicular to the central axis AX1 of the cover 1 (see the front view shown in the center of Fig. 17).

[0062] The lid body 1 is made of, for example, resin. The lid body 1 is made of opaque resin (for example, black resin). In the example shown in FIG. 17, the lid body 1 is made of only one resin part formed by integral molding. Since the number of parts of the lid body 1 is one, the manufacturing cost of the lid body 1 is reduced.

[0063] The lid 1 preferably has a rigidity that does not cause plastic deformation during normal use. In the example shown in FIG. 15, the thickness T1 of the skirt 2 is, for example, 0.7 mm or more, more preferably 1 mm or more. The thickness T2 of the top plate 3 is, for example, 1 mm or more, more preferably 2 mm or more. The lid 1 is preferably capable of being repeatedly used 10 times or more by being washed. The repeated use of the lid 1 reduces the burden on the environment. The cup-shaped container 9 to which the lid 1 is attached is preferably a rigid container. The cup-shaped container 9 is, for example, made of metal (more specifically, made of stainless steel).

[0064] In the example shown in FIG. 15, the cone 37 (e.g., the cone 370) is solid. Alternatively, as illustrated in FIG. 19, the cone 37 (e.g., the cone 370) may be hollow. When the cone 37 is hollow, the heat insulating properties of the top plate 3 are improved. In the example shown in FIG. 19, the top plate 3 has a top wall 30a and a bottom wall 30b. In addition, an insulating space 3p is formed between the top wall 30a of the top plate 3 and the bottom wall 30b of the top plate 3. The insulating space 3p is filled with air, for example. The lid 1 shown in FIG. 19 differs from the lid 1 shown in FIG. 15 in that the cone 37 is hollow and that the top surface 31a of the top plate 3 is a flat surface without a recess. In other respects, the lid 1 shown in FIG. 19 is similar to the lid 1 shown in FIG. 15. In the example shown in FIG. 19, the top surface 31a of the top plate 3 may have a recess.

[0065] In the example shown in Fig. 15, the pyramid 37 is thicker than other parts of the top plate 3 (e.g., the outer edge portion 32 of the top plate 3). Alternatively, as illustrated in Fig. 20, the thickness of the pyramid 37 may be equal to the thickness of other parts of the top plate 3 (e.g., the outer edge portion 32 of the top plate 3).

[0066] In the example shown in FIG. 15, the thickness of the cone 37 increases toward the central axis AX1 of the top plate 3. Alternatively, as illustrated in FIG. 20, the thickness of the cone 37 may be substantially constant regardless of the distance from the central axis AX1 of the top plate. When the thickness of the cone 37 is constant, defective products are less likely to be produced when the cone 37 is molded. In the example shown in FIG. 20, the cone 37 is a shell-shaped (in other words, shell-shaped) cone. When the cone 37 is shell-shaped (in other words, when the thickness of the cone 37 is not excessively large), defective products are less likely to be produced when the cone 37 is molded.

[0067] 15, bottom surface 312a of recess 311a formed in top surface 31a of table top 3 is a surface that is approximately perpendicular to central axis AX1 of table top 3. In contrast, in the example shown in Fig. 20, bottom surface 312a of recess 311a formed in top surface 31a of table top 3 is an inclined surface that becomes deeper toward central axis AX1 of table top 3.

[0068] Second embodiment A combination of a lid 1 for a cup-shaped container and a cup-shaped container 9 in the second embodiment will be described with reference to Figures 1 to 21. Figure 21 is a schematic cross-sectional view showing the combination of a lid 1 for a cup-shaped container and a cup-shaped container 9 in the second embodiment.

[0069] In the second embodiment, the differences from the first embodiment will be mainly described, and the repetitive description of the matters already described in the first embodiment will be omitted. Therefore, it goes without saying that the matters already described in the first embodiment can be adopted in the second embodiment even if they are not explicitly described in the second embodiment. Furthermore, the matters described in the second embodiment can be applied to the first embodiment.

[0070] The combination of the lid body 1 for a cup-shaped container and the cup-shaped container 9 in the second embodiment is the combination of the lid body 1 for a cup-shaped container and the cup-shaped container 9 in the first embodiment. Since the lid body 1 for a cup-shaped container has been described in the first embodiment, repeated description of the lid body 1 for a cup-shaped container will be omitted.

[0071] The cup-shaped container 9 is made of, for example, metal (more specifically, stainless steel). The cup-shaped container 9 is preferably a heat-insulating container. In this case, when cold food or drink is stored in the cup-shaped container 9, water droplets are unlikely to adhere to an outer surface 91t of the side wall 91 of the cup-shaped container 9. This prevents or suppresses water droplets from dripping onto a placement surface such as a desk DK. In the example shown in FIG. 21, the side wall 91 of the cup-shaped container 9 has an outer wall 911, an inner wall 912, and a cavity 913 disposed between the outer wall 911 and the inner wall 912. The cavity 913 may be a vacuum. Alternatively, the cavity 913 may be filled with a gas such as air.

[0072] It is preferable that the cup-shaped container 9 is more durable than the lid 1. In this case, the cup-shaped container 9 can be reused a greater number of times than the lid 1. This further reduces the burden on the environment.

[0073] 21, the distance L2 between the outer edge e1 of the top surface 31a of the tabletop 3 and the central axis AX1 of the tabletop 3 is greater than the distance L3 between the outer edge e2 of the bottom surface 31b of the tabletop 3 and the central axis AX1 of the tabletop 3. In this case, it is easy to hook a finger on the outer side surface 31c of the tabletop 3. This makes it easy to remove the lid 1 from the cup-shaped container 9.

[0074] 21, the distance L3 is greater than the distance L4 between the upper end of the outer surface 91t of the side wall 91 of the cup-shaped container 9 and the central axis AX1 of the top plate 3. In this case, it is even easier to hook a finger on the top plate 3. This makes it easier to remove the lid 1 from the cup-shaped container 9.

[0075] The cup-shaped container 9 may be a container with a handle or a container without a handle. Food and drink contained in the cup-shaped container 9 are, for example, coffee-based drinks such as hot coffee and hot caffe latte, hot black tea, hot Japanese tea, hot soup, hot miso soup, hot clear soup, hot water, iced coffee, iced coffee-based drinks, iced tea, alcoholic drinks, non-alcoholic drinks, carbonated drinks, non-carbonated drinks, cold water, and the like.

[0076] The present invention is not limited to the above-mentioned embodiments or modifications, and it is clear that each embodiment or modification can be appropriately modified or changed within the scope of the technical idea of ​​the present invention. In addition, various techniques used in each embodiment or modification can be applied to other embodiments or other modifications as long as no technical contradiction occurs. Furthermore, any additional configuration in each embodiment or modification can be omitted as appropriate. [Explanation of symbols]
