DETAILED DESCRIPTION

[0040] As one embodiment of the present application, for example, a container with a lid provided with a lid as shown in Figures 1-4 will be described.

[0041] Further, Figure 1 is a sectional view showing the structure of a container with a lid 100 provided with the lid 1. Figure 2 is a perspective view showing the appearance of the lid 1. Figure 3 is a sectional view showing the structure of the lid 1. Figure 4 is a schematic view for explaining the use of the lid 1.

[0042] As Figure 1 shown, the container with a lid 100 of the present embodiment is provided with the lid 1 and a container main body 2. The container with a lid 100 is a tea cup (beverage container) that enables keeping warm or cold of a beverage (contents) housed in the container main body 2 by the container main body 2 having a vacuum heat insulating structure.

[0043] Specifically, the container body 2 is composed of a double-layered container, which has a bottomed cylindrical outer container 3 made of, for example, stainless steel, and an inner container 4, and the two are joined together at their mouths so that the inner container 4 is housed inside the outer container 3. Furthermore, a vacuum insulation layer 5 is provided between the outer container 3 and the inner container 4. The vacuum insulation layer 5 can be formed, for example, by blocking a degassing hole located at the center of the bottom surface of the outer container 3 within a chamber that has been depressurized (evacuated) to a high vacuum.

[0044] The container body 2 has a generally circular bottom part 2a and a generally cylindrical body part 2b that rises from the outer periphery of the bottom part 2a. The upper end of the body part 2b serves as the upper opening 2c of the container body 2 and has a circular opening.

[0045] Furthermore, while the container body 2 of this embodiment has a generally cylindrical shape as a whole, the shape of the container body 2 is not particularly limited and can be appropriately modified according to size, design, etc. In addition, the outer peripheral surface of the container body 2 can also be coated or printed.

[0046] like Figures 1-3 As shown, the lid 1 of this embodiment is used by inserting into the inside of the container body 2 from the upper opening 2c of the container body 2, and has a lid body 6, a leg 7 and a handle 8.

[0047] The cover 1 has an upper part 1a and a lower part 1b made of, for example, a heat-resistant resin such as polypropylene, and is formed by integrating the upper part 1a and the lower part 1b by means of welding or the like.

[0048] The lid body 6 and the inner side of the container body 2 are integrally formed into a generally circular plate shape. Furthermore, the outer diameter of the lid body 6 is slightly smaller than the inner diameter of the container body 2. Specifically, the difference between the outer diameter of the lid body 6 and the inner diameter of the container body 2 is preferably at least 0.5 mm. Moreover, in this embodiment, the optimal difference between the outer diameter of the lid body 6 and the inner diameter of the container body 2 is 2.7 mm.

[0049] A heat insulation layer 9 with a shape corresponding to the cover body 6 (generally a circular plate shape in this embodiment) is provided inside the cover body 6. The heat insulation layer 9 is disposed in the space K provided between the upper side member 1a and the lower side member 1b constituting the cover body 6.

[0050] The insulation layer 9 is made of a foamed insulation material, such as foamed polyurethane resin. Alternatively, instead of the aforementioned foamed insulation material, the insulation layer 9 can also be a space composed of air.

[0051] Therefore, in the lid 1 of this embodiment, the lid body 6 can be made heat-insulating. In addition, when embedded inside the container body 2, it can float in the beverage inside the container body 2.

[0052] Multiple legs 7 are arranged around the cover body 6 (three in this embodiment). The multiple legs 7 are arranged at equal intervals around the cover body 6 and have the same shape as each other.

[0053] Specifically, each leg 7 is configured to extend downward from around the cover body 6, which is composed of the lower part 1b. When viewed from above, each leg 7 has a shape that curves in an arc along the inner surface of the container body 2. On the other hand, when viewed from the side, each leg 7 has a shape that is inclined in a manner that draws a sine curve with its front end sandwiched between it.

[0054] Furthermore, the multiple legs 7 are not limited to a structure in which they are circumferentially separated from each other in the cover body 6, but can also be a structure in which they are circumferentially continuous in the cover body 6.

[0055] The gripping part 8 is a part for the user to hold, and it is configured to protrude in a fin-like shape from the center of the upper surface of the cover body 6, which is composed of upper components.

[0056] In the lidded container 100 of this embodiment, which has a lid 1 having the structure described above, such as Figure 1 As shown, with the lid 1 embedded inside the container body 2, the lid body 6 is kept floating in the beverage L inside the container body 2, thus covering the liquid surface.

[0057] From that state onwards, as Figure 4 As shown, when the container body 2 is tilted, the leg 7 abuts against the inner surface of the container body 2 while preventing the lid body 6 from tilting inside the container body 2. This allows the beverage L to flow out towards the upper opening 2c through the gap S formed between the inner surface of the container body 2 and the lid body 6.

[0058] In the lidded container 100 of this embodiment, the lid 1 is used such that when the container body 2 is tilted, the lid body 6 will not tilt inside the container body 2, so the lid body 6 will not touch the mouth until the beverage L is finished, and thus will not become an obstacle.

[0059] Here, when the container body 2 is tilted, in order to prevent the lid body 6 from tilting inside the container body 2, the relationship between the outer diameter of the lid body 6 and the length of the leg 7 can be calculated using the following formula.

[0060] (Outer diameter of lid body 6) = ((Inner diameter of container body 2) 2 - (Length of leg 7 + Height of outer perimeter of cover body 6)2 1 / 2

[0061] For example, in the present embodiment, the inner diameter of the container body 2 is formed to be 69 mm, and the height of the outer peripheral portion of the lid body 6 is formed to be 5.5 mm. Therefore, in a case where the outer diameter of the lid body 6 is formed to be y and the length of the leg portion 7 is formed to be x, the above-described relationship becomes the following equation (1), and therefore it is possible to express it using a graph as shown in FIG. 8. Figure 5

[0062] y = (69 2 - (x + 5.5) 2 ) 1 / 2 … (1)

[0063] In this case, as shown in the graph of FIG. 8, by making the length x of the leg portion 7 longer with respect to the outer diameter y of the lid body 6, it is possible to prevent the lid body 6 from tilting inside the container body 2 when the container body 2 is tilted. Figure 5

[0064] For example, in a case where the outer diameter y of the lid body 6 is 68 mm, if the length x of the leg portion 7 is made to be 6.2 mm or more (if the height of the outer peripheral portion of the lid body 6 is included, the total height is 11.7 mm), it is possible to prevent the lid body 6 from tilting inside the container body 2 when the container body 2 is tilted.

[0065] As described above, in the covered container 100 using the lid 1 of the present embodiment, it is possible to drink the beverage L inside the container body 2 while keeping it warm by the lid 1 without performing the conventional opening and closing operation based on the lid, and therefore it is possible to further improve the convenience of use.

[0066] Furthermore, the present application is not necessarily limited to the above-described embodiment, and various modifications can be applied within a range not departing from the gist of the present application.

[0067] For example, as another embodiment of the present application, it is also possible to form a structure as shown in a lid 1A of FIG. 9. Furthermore, Figure 6 is a perspective view showing the structure of the lid 1A. Figure 6

[0068] Specifically, the lid 1A has a lid body 6A, a plurality of (three in the present embodiment) leg portions 7A, a cutout portion 10, and a grip portion 8A, and is composed of a member molded in one piece by a heat-resistant resin such as polypropylene.

[0069] ​​​​The lid main body 6A is formed in a substantially circular plate shape corresponding to the inner side of the container main body 2. A plurality of leg portions 7A are arranged at intervals around the periphery of the lid main body 6A and are provided so as to extend downward from the periphery of the lid main body 6A. In the present embodiment, two of the three leg portions 7A are arranged on the two sides across the cutout portion 10, and one leg portion 7A is arranged on the side opposite the cutout portion 10.

[0070] When the lid 1A is viewed from above, each leg portion 7A has a shape curved in a circular arc shape along the inner surface of the container main body 2. On the other hand, when the lid 1A is viewed from the side, each leg portion 7A has a linear shape toward the front end thereof.

[0071] The cutout portion 10 is provided so as to cut a portion of the periphery of the lid main body 6 in a circular arc shape. The grip portion 8A is provided so as to protrude upward from the periphery of the cutout portion 10.

[0072] In the capped container 100 provided with the lid 1A of the present embodiment having the above-described structure, as in the case where the lid 1 illustrated in FIG. 1 is used, in a state where the lid 1A is fitted to the inner side of the container main body 2, the lid main body 6 covers the liquid surface in a state where the beverage L held in the container main body 2 is floating. Figure 1

[0073] From this state, when the container main body 2 is tilted, the center of gravity of the lid 1A is located on the cutout portion 10 side, and thus the lid 1A rotates in the container main body 2 in a manner such that the cutout portion 10 side becomes downward. In addition, when the container main body 2 is tilted, the leg portions 7A are brought into abutment with the inner surface of the container main body 2, and the lid main body 6A is prevented from tilting in the container main body 2. Thus, it is possible to drink the beverage L flowing out toward the upper portion opening 2c side through the liquid passage H formed between the inner surface of the container main body 2 and the cutout portion 10.

[0074] In the capped container 100 of the present embodiment, by using the lid 1A, when the container main body 2 is tilted, the lid main body 6A does not tilt in the container main body 2, and thus the lid main body 6A does not come into contact with the mouth until the beverage L is finished being drunk, and thus does not become an obstacle.

[0075] As described above, in the capped container 100 using the lid 1A of the present embodiment, it is possible to drink the beverage L in the container main body 2 while keeping warm by the lid 1A without performing the lid-based opening and closing operation as in the past, and thus it is possible to further improve the use convenience.

[0076] ​Further, in the above-described embodiments, the case where the present application is applied to a beverage container having a heat retaining or heat keeping function by the container body 2 having the above-described vacuum heat insulating structure is exemplified, but the present application is not necessarily limited to such a beverage container, and can be widely applied to a covered container using a lid body which is inserted into the inside of a container body from the upper opening of the container body.
