DETAILED DESCRIPTION

[0019] A cap and a container with a cap according to an embodiment of the present invention will be described with reference to the drawings.

[0020] like Figure 1 and Figure 2 As shown, the container 10 with a lid includes a container body 30 and a lid 20 that closes the opening of the container body 30. The container 10 with a lid is a rice bowl for storing food, especially steaming food, such as cooked rice, that is, cooked rice. The container 10 with a lid is formed in a size that can store 0.2 liters of cooked rice.

[0021] The container body 30 is in the shape of a bottomed cylinder that opens upward. The above-mentioned food is contained in the container body 30. The container body 30 is a double-layer structure made of metal (for example, stainless steel) consisting of an inner cylinder 30a with a bottom and an outer cylinder 30b with a bottom that covers the outer side of the inner cylinder 30a, and has a vacuum insulation structure with a vacuum insulation layer 30c between the inner cylinder 30a and the outer cylinder 30b.

[0022] The cover 20 is formed in a substantially disk shape so as to close the opening of the container body 30. The cover 20 includes an outer cover 21, an inner cover 25, and a heat insulator 26. The outer cover 21 and the inner cover 25 are formed of, for example, heat-resistant resin.

[0023] In addition, in the following description, Figure 1 to Figure 5 The direction in which the central axis O shown in the figure extends is defined as the up-down direction, and the direction perpendicular to the central axis O is defined as the horizontal direction. The up-down direction can be referred to as the height direction. Figure 2 In the embodiment, the direction from the container body 30 toward the cover 20 is defined as the upper side, and the direction from the cover 20 toward the container body 30 is defined as the lower side. In addition, the horizontal direction can be referred to as the radial direction. Figure 2 The side close to the central axis O is set as the radial inner side, the inner peripheral side or just the inner side. Figure 2 In the diagram, the side away from the central axis O is referred to as the radially outer side, the outer peripheral side, or simply the outer side. In addition, the rotation direction around the central axis O is referred to as the circumferential direction.

[0024] like Figure 1 As shown, the outer cover 21 is exposed to the outside of the lidded container 10 when the cover 20 is mounted on the container body 30. The outer cover 21 includes a top surface 21a covering the upper part and a peripheral wall portion 21b provided to be suspended from the outer peripheral end of the top surface 21a over the entire circumference. In addition, the outer cover 21 includes a gripping portion 22 provided to protrude upward from the top surface 21a, vertical leg portions 23a to 23d, and engaging protrusions 29a to 29d.

[0025] The central axis O extends along the up-down (height) direction of the cover 20 and passes through the center of the top surface 21a of the cover 20. The gripping portion 22 is formed convexly upward in a manner passing through the central axis O of the cover 20 and along the radial direction of the top surface 21a. When the cover 20 is viewed from above, the gripping portion 22 is formed in a substantially rectangular shape in a manner that divides the top surface 21a of the cover 20 into two parts. The width W of the gripping portion 22 along the short side direction is formed to gradually increase as it moves away from the central axis O of the cover 20 in the radial direction. In other words, the width W of the gripping portion 22 along the short side direction is shortest on the central axis O. The gripping portion 22 is formed so as to be gripped by the user's fingers from the width W direction (short side direction).

[0026] In addition, Figure 1 and Figure 2 In the use state of the cover 20 shown in FIG. 1 , the top surface 21a is located at the top, and the peripheral wall portion 21b is located at the entire circumference in the horizontal direction. Figure 4A , Figure 4B As shown in FIG. 1 , a state in which one end side of the peripheral wall portion 21 b is located at a position facing a tabletop T described later is defined as a vertically placed state of the cover 20 or a vertically self-standing state.

[0027] like Figure 4B As shown, the upper surface of the gripping portion 22 is formed into a curved concave shape that becomes deeper downward as it approaches the central axis O in the longitudinal direction of the gripping portion 22. Thus, when two covers 20, namely, covers 20A and 20B are stacked (see FIG. 2 ), the upper surface of the gripping portion 22 is formed into a curved concave shape that becomes deeper downward as it approaches the central axis O. Figure 5 ), it is possible to suppress the upper surface of the gripping portion 22 of the cover 20A and the cover lower surface 25a (see Figure 3 )touch.

[0028] In addition, if Figure 1 As shown, the top surface 21a of the outer cover 21 is in a substantially hemispherical concave shape that becomes deeper downward as it approaches the central axis O. Since the top surface 21a is concave, the grip portion 22 is formed so that the height H of the side surfaces in the short direction increases as it approaches the central axis O in the long direction. As a result, the area of ​​the side surfaces in the short direction near the central axis O of the grip portion 22 becomes larger, and the user can easily grip the grip portion 22 from the width W direction (short direction).

[0029] like Figure 5As shown in the figure, when the cover 20B independent of the cover 20A is stacked on the upper surface of the cover 20A, the fitting protrusions 29a to 29d of the cover 20A are fitted into the fitting recesses 27a to 27d described later of the cover 20B independent of the cover 20A. At this time, the cover 20B is in a state of being rotated 90° in the circumferential direction with respect to the cover 20A around the central axis O of the covers 20A and 20B.

[0030] like Figure 1 As shown in FIG. 1 , the engaging protrusions 29a to 29d are erected on the outer peripheral side of the top surface 21a of the outer cover 21. The two engaging protrusions 29a and 29b are located on one end surface ( Figure 1 On both sides of the width W direction of the right end surface of the holding portion 22, it is in the shape of a wall extending in the long side direction of the holding portion 22. A gap portion 29e is formed between the two fitting protrusions 29a and 29b.

[0031] The two fitting protrusions 29c and 29d are located on the other end surface ( Figure 1 On both sides of the width W direction of the left end surface of the holding portion 22, it is in the shape of a wall extending in the long side direction of the holding portion 22. A gap portion 29f is formed between the two fitting protrusions 29c and 29d.

[0032] like Figure 1 and Figure 4A , Figure 4B As shown, the vertical legs 23a to 23d extend radially outward from the peripheral wall 21b of the cover 20 and are formed into a convex shape extending in the up-down (height) direction of the cover 20. The vertical legs 23a to 23d are formed in a range extending upward from the peripheral wall 21b in addition to the up-down width (height) of the peripheral wall 21b of the cover 20. The vertical legs 23a to 23d are formed in the same flat plate shape in a manner continuous with the corresponding engaging protrusions 29a to 29d. That is, the vertical legs 23a to 23d and the engaging protrusions 29a to 29d are integrally formed in an L-shaped plate shape along the outer peripheral side of the peripheral wall 21b and the top surface 21a of the cover 20. Two engaging protrusions 29a to 29d are formed at each of the two ends in the long side direction of the grip 22.

[0033] The vertical legs 23a and 23b are respectively arranged at positions separated by 180° from the vertical legs 23d and 23c along the circumferential direction of the central axis O of the cover 20 (so-called rotationally symmetrical positions). The two adjacent vertical legs 23a and 23b are approximately parallel on both sides of the width W direction of the gripping portion 22 through the gap 29e, and by simultaneously contacting the table top T, the cover 20 is vertically self-supporting with respect to the table top T in such a manner that the long side direction of the gripping portion 22 becomes the up-down direction. Similarly, the two adjacent vertical legs 23c and 23d are approximately parallel on both sides of the width W direction of the gripping portion 22 through the gap 29f, and by simultaneously contacting the table top T, the cover 20 is vertically self-supporting with respect to the table top T in such a manner that the long side direction of the gripping portion 22 becomes the up-down direction. In addition, the table top T is an example of a cover installation surface, and refers to a place where the cover 20 can be placed, such as a dining table, a kitchen counter, etc.

[0034] When the cover 20 stands on its own, the contact portion 23s (see Figure 4B ) is inclined in a manner approaching the central axis O as it goes upward. As a result, the cover 20 stands on its own in a direction from the upper side (top surface 21a side) toward the table top T, slightly (as an example, 3° to 7°) inclined relative to the vertical direction of the table top T. In this way, the cover 20 stands on its own in an inclined manner, so that the exposure portions 24a, 24b described later are inclined in a manner such that the lower front ends of the exposure portions 24a, 24b are away from the table top T.

[0035] The contact portion 23s is formed to be curved concavely radially inward. The contact portion 23s contacts the table top T at two points P1 and P2 at both ends. Therefore, the contact portion 23s can contact the table top T by point contact, and the cover 20 can stand independently in a vertical position stably.

[0036] like Figure 2 and Figure 3 As shown, the lid 20 is formed by disposing a heat insulating member 26 on the lower surface side of the outer lid 21, further disposing an inner lid 25 on the lower surface side of the heat insulating member 26 and overlapping them, and combining the outer lid 21 and the inner lid 25 around each other. The heat insulating member 26 is filled throughout the entire area of ​​the space between the inner lid 25 and the outer lid 21, thereby improving the heat preservation performance of the lidded container 10.

[0037] like Figure 3 As shown, the inner cover portion 25 includes a cover lower surface 25a and a wall portion 25b.

[0038] The cover lower surface 25a is dome-shaped and bulges downward convexly about the central axis O. This can improve the strength of the cover 20, and since the cover lower surface 25a is also dome-shaped when the cover 20 is thermally deformed, deformation of the cover lower surface 25a is less noticeable.

[0039] The cover lower surface 25a includes a steep slope surface 25c formed inside the periphery of the exposed portions 24a and 24b. The steep slope surface 25c is formed to have a greater slope than the region other than the steep slope surface 25c in the cover lower surface 25a.

[0040] The wall portion 25b is formed in a wall shape standing downward so as to surround the entire circumference of the lower surface 25a of the cover on the outer peripheral side. When viewed from the bottom direction of the cover 20, the wall portion 25b is roughly circular. The wall portion 25b of the cover 20 on the side having the longitudinal legs 23a and 23b on the radial outer side has the exposure portion 24a, and the wall portion 25b on the side having the longitudinal legs 23c and 23d on the radial outer side has the exposure portion 24b. That is, the exposure portion 24a and the longitudinal legs 23a and 23b are arranged to be arranged on the radial inner side and outer side of the cover 20, and similarly, the exposure portion 24b and the longitudinal legs 23c and 23d are arranged to be arranged on the radial inner side and outer side of the cover 20.

[0041] The wall portion 25b has fitting recesses 27a to 27d in a part thereof. The fitting recesses 27a to 27d are formed in a concave shape by cutting off a part of the wall portion 25b, and the fitting recesses 27a and 27b, and the fitting recesses 27c and 27d are respectively arranged to be adjacent in the circumferential direction. The locking protrusions 27e and 27f are respectively formed between the fitting recesses 27a and 27b and between the fitting recesses 27c and 27d in the wall portion 25b. The locking protrusions 27e and 27f are formed as a part of the wall portion 25b to stand upright in a wall shape facing downward, and their height H1 is formed to be lower than the wall height H2 of the part of the wall portion 25b where the exposed portions 24a and 24b are formed. The wall portion 25b has an inclined portion 25d, and the inclined portion 25d is formed so that the wall height becomes higher as it approaches the exposed portions 24a and 24b from the fitting recesses 27a to 27d.

[0042] like Figure 3 and Figure 5 As shown, the fitting recesses 27a to 27d of the cover 20B are fitted with the fitting protrusions 29a to 29d of the other cover 20A. The fitting recesses 27a to 27d are rectangular holes, and have a hole width greater than the thickness of the fitting protrusions 29a to 29d in the circumferential direction of the cover 20. The fitting recesses 27a and 27b are respectively provided at positions separated by 180° in the circumferential direction of the central axis O of the cover 20 with respect to the fitting recesses 27d and 27c (so-called rotationally symmetrical positions).

[0043] like Figure 3 and Figure 5 As shown, the locking protrusion 27e of the cover 20B is embedded in the gap 29e of the other cover 20A. Similarly, the locking protrusion 27f of the cover 20B is embedded in the gap 29f of the other cover 20A. The locking protrusions 27e and 27f are provided at positions separated by 180° in the circumferential direction of the central axis O of the cover 20 (so-called rotationally symmetrical positions).

[0044] like Figure 5 As shown, when the cover 20B is overlapped on the upper surface of the other cover 20A, even if the direction is slightly offset, the inclined portion 25d of the cover 20B slides relative to at least one of the engaging convex portions 29a to 29d and the gripping portion 22, so that the engaging convex portions 29a to 29d of the cover 20A can be guided to the engaging concave portions 27a to 27d. In addition, the engaging concave portions 27a to 27d and the inclined portion 25 can ensure a gap that communicates between the wall portion 25b of the cover 20B and the outside when the covers 20A and 20B are overlapped. The gap can be used to immerse the covers 20A and 20B in a cleaning liquid for cleaning in a state where the covers 20A and 20B are overlapped, and to efficiently dry them when they are placed in a dryer, thereby managing them hygienically.

[0045] When the covers 20A and 20B are stacked, the lower ends of the exposed portions 24a and 24b of the covers 20A and 20B are in contact with the top surface 21a or the storage surface G. The storage surface G is a place where the covers 20 can be placed, such as a kitchen counter or a storage rack.

[0046] The dew-receiving portions 24a and 24b receive water drops attached to the inner cover portion 25 due to condensation when the cover 20 is placed vertically on the table T, and together with the steep slope surface 25c and the wall portion 25b, form an enclosed space S. The dew-receiving portions 24a and 24b are respectively located between the fitting recesses 27a and 27b and the fitting recesses 27c and 27d around the central axis O of the cover 20. In this example, the fitting recesses 27a and 27b → the dew-receiving portion 24a → the fitting recesses 27d and 27c → the dew-receiving portion 24b are sequentially arranged at intervals of 90° in the circumferential direction of the wall portion 25b.

[0047] The exposed portions 24a and 24b can increase the wall height H2 of the exposed portions 24a and 24b by the steep slope surface 25c, thereby increasing the volume of the space S formed by the steep slope surface 25c, the exposed portions 24a and 24b, and the wall portion 25b, and forming the space S deeper downward. Figure 4A , Figure 4B As shown, when the cover 20 is tilted and self-supporting, the steep slope surface 25c is greatly inclined in the direction away from the lower front end of the exposed portion 24a, 24b, and the desktop T side ( Figure 4A , Figure 4B The lower front ends of the exposed portions 24a and 24b (the lower side in the figure) are further inclined relative to the table top T in a manner away from the table top T. Therefore, the volume of the space S can be increased, and the space S can be formed deeper downward.

[0048] When the cover 20 is placed vertically, the dew receiving portions 24a and 24b have the function of receiving water drops attached to the inner cover portion 25 due to condensation. In addition, the space S can store the water received by the dew receiving portions 24a and 24b inside. Thus, as the above-mentioned effect, the amount of water that can be stored (received) in the space S is increased, and the stored water can be prevented from flowing out from the lower front end of the dew receiving portions 24a and 24b to the outside.

[0049] In addition, the exposed portions 24a and 24b are formed so that a part of the wall portion 25b becomes a flat plate. Therefore, the water in the space S is accumulated in a spreading manner along the flat plate, and is not concentrated in one place, and a part of the exposed portions 24a and 24b can be prevented from becoming a flow path for the accumulated water, thereby preventing the water from flowing out from the lower front end of the exposed portions 24a and 24b to the outside.

[0050] Next, a method of vertically placing the lid 20 will be described. At the beginning of this description, food (cooked rice) is contained in the container body 30, and water droplets due to condensation adhere to the lid lower surface 25a of the lid 20 closing the opening of the container body 30.

[0051] The user holds the gripping portion 22 of the cap 20 in the width W direction (short side direction), and removes the cap 20 from the container body 30 while holding the gripping portion 22. Figure 1 As shown by the arrow Ar, the cover 20 is opened in such a manner that the long side direction of the gripping portion 22 is oriented along the up-down (height) direction. Figure 4A , Figure 4B As shown, the user makes the cover 20 vertically relative to the table T, makes the vertical legs 23a, 23b of the cover 20 contact the table T, and releases the hand from the grip 22. As a result, the vertical legs 23a, 23b contact the table T at the same time, and the cover 20 stands vertically. When the cover 20 is oriented vertically, water droplets attached to the cover lower surface 25a fall along the cover lower surface 25a or the inner surface of the wall 25b due to their own weight, and the fallen water accumulates in the space S. The dew receiving portion 24a suppresses the water accompanying condensation from falling onto the table T. In addition, the cover 20 stands vertically on the table T, so the cover lower surface 25a does not contact the table T, and water does not adhere to the table T.

[0052] Next, refer to Figure 5 The method of stacking the covers 20A and 20B will be described. The stacking operation is performed in a storage area or a workbench for the covers 20A and 20B.

[0053] First, the user sets the cover 20A on the storage surface G in such a manner that the lower front end portions of the exposed portions 24a and 24b of the cover 20A contact the storage surface G. Next, a cover 20B is prepared that is independent of the set cover 20A, and the other cover 20B is rotated 90 degrees relative to the cover 20A around the central axis O of the cover 20A, so that the lower surface of the cover 20B approaches the upper surface of the cover 20A. As a result, the fitting recesses 27a to 27d of the cover 20B are fitted into the fitting protrusions 29a to 29d of the cover 20A. As a result, the two covers 20A and 20B are stacked, and the covers 20A and 20B can be compactly placed and stored in a storage place or the like. In the stacked state of the covers 20A and 20B, the relative rotation of the covers 20A and 20B around the central axis O is restricted by the fitting protrusions 29a to 29d and the fitting recesses 27a to 27d. This can prevent the stacked covers 20A and 20B from collapsing.

[0054] Similarly, when the two covers 20A and 20B are stacked, the interspace 29e of the other cover 20A fits into the locking protrusion 27e of the cover 20B, and the interspace 29f of the other cover 20A fits into the locking protrusion 27f of the cover 20B. Thus, when the covers 20A and 20B are stacked, the interspaces 29e and 29f fit into the locking protrusions 27e and 27f, thereby limiting the relative rotation of the covers 20A and 20B around the central axis O and limiting the radial displacement of the grip 22 in the long side direction. Thus, the stacked covers 20A and 20B can be prevented from collapsing.

[0055] In this example, two covers 20A and 20B are stacked, but three or more covers 20 may be stacked.

[0056] In addition, when the lower surface of the cover 20B is brought close to the upper surface of the cover 20A in a state where the cover 20B deviates from a specified angle of 90° around the center axis O relative to the cover 20A, any one of the engaging protrusions 29a~29d of the cover 20A contacts and slides with the inclined portion 25d and the holding portion 22 of the wall portion 25b of the cover 20B, whereby the engaging protrusions 29a~29d are guided to be embedded in the engaging recesses 27a~27d.

[0057] (Effect)

[0058] According to the above-described embodiment, the following effects are achieved.

[0059] (1-1) The lid 20 for blocking the opening of the container body 30 for storing food comprises: a gripping portion 22 formed on the top surface 21a of the lid 20 and gripped by a user; and longitudinal legs 23a, 23b or 23c, 23d as an example of a self-supporting contact portion, formed on the peripheral wall portion 21b of the lid 20 and in contact with a table top T as an example of a lid setting surface in a manner that the lid 20 is longitudinally self-supporting relative to the table top T.

[0060] According to this structure, the cover 20 can stand on its own by the vertical leg parts 23a, 23b or 23c, 23d formed in the peripheral wall part 21b of the cover 20. Thus, the cover 20 can be made to stand on its own by a simpler structure.

[0061] Since the cover 20 can stand on its own and has a simple structure, the cover 20 can be easily stored in a dishwasher or a storage rack, and can be stored stably while saving space.

[0062] In addition, in the structure described in Patent Document 1, there is the work of pulling up the hanging portion in order to make the cover self-standing, but in the above structure, there is no such work, and the cover 20 can be easily made self-standing.

[0063] By making the cover 20 self-standing vertically, the space occupied by the cover 20 on the table T can be reduced. In addition, by making the cover 20 self-standing vertically, the cover lower surface 25a that may directly contact food does not contact the table T, and the cover lower surface 25a can be kept clean.

[0064] (1-2) The gripping portion 22 passes through the central axis O and its long side direction extends along the radial direction of the circular top surface 21a, and the gripping portion 22 is gripped by the user from the width direction (short side direction). The vertical legs 23a, 23b or 23c, 23d are located on the outer sides of the two ends of the gripping portion 22 in the long side direction, are convex on the peripheral wall portion 21b of the cover 20, and extend in the vertical (height) direction of the cover 20, so that the cover 20 is self-supporting in the longitudinal direction of the table T and contacts the table T at positions separated from each other at the same time.

[0065] According to this structure, when the cover 20 is made to stand on the table T, the plurality of vertical legs 23a, 23b or 23c, 23d come into contact with the table T, so that the cover 20 can be made to stand on its own more stably.

[0066] (1-3) The cover 20 includes: a liquid receiving portion 24a, 24b as an example of a liquid receiving portion, which is provided upright on the cover lower surface 25a, and receives liquid that falls on the cover lower surface 25a due to its own weight when the cover 20 stands vertically relative to the table T.

[0067] According to this structure, the water adhering to the cover lower surface 25a can be prevented from falling onto the table top T by the exposure portions 24a and 24b when the cover 20 is made to stand on its own.

[0068] (1-4) The exposure contact portion 24 a and the vertical leg portions 23 a and 23 b are arranged so as to be aligned on the radial inner side and the radial outer side of the cover 20 .

[0069] According to this structure, when the cover 20 stands on its own with the vertical legs 23a and 23b in contact with the table T, the exposure portion 24a is located closer to the table T (i.e., in the direction of gravity) relative to the central axis O. Therefore, the exposure portion 24a can more reliably receive water falling due to its own weight, so that the water received by the exposure portions 24a and 24b can be stored in the space S.

[0070] (1-5) The vertical legs 23a to 23d tilt the cover 20 in the vertical direction relative to the table T so that the exposure portions 24a and 24b are oriented away from the table T as they move away from the cover lower surface 25a when the cover 20 stands vertically on the table T.

[0071] According to this structure, the water received by the exposed parts 24a and 24b and accumulated in the space S can be prevented from falling onto the table top T. Thus, the table top T can be prevented from being contaminated by water or food.

[0072] (1-6) The cover 20 includes: engagement protrusions 29a to 29d as an example of an engagement portion, which are formed on the outer peripheral side of the top surface 21a of the cover 20 and are convex; and engagement recesses 27a to 27d as an example of an engaged portion, which are formed on the wall portion 25b on the outer peripheral side of the cover lower surface 25a and are concave, and are provided at positions that are different from the engagement protrusions 29a to 29d by a predetermined angle (for example, 90°) around the central axis O of the cover 20. The cover 20B is configured to be stacked on another cover 20A having the same shape as the cover 20B in the upper (height) direction. The engagement recesses 27a to 27d of the cover 20B are configured to fit into the engagement protrusions 29a to 29d of the other cover 20A when the cover 20B is stacked at an angle of 90° around the central axis O of the cover 20B relative to the other cover 20A.

[0073] According to this structure, the fitting protrusions 29a to 29d and the fitting recesses 27a to 27d are provided on the outer peripheral sides of the covers 20A and 20B and at positions separated around the central axis O of the cover 20. Thus, the plurality of covers 20A and 20B can be stacked more stably.

[0074] (2-1) The lid 20 for closing the opening of the container body 30 for storing food comprises: a gripping portion 22 to be gripped by a user; engaging convex portions 29a to 29d as an example of an engaging portion, which are formed on the outer peripheral side of the top surface 21a of the lid 20 and are convex; and engaging concave portions 27a to 27d, which are formed on the outer peripheral side of the lid lower surface 25a in the wall portion 25b, are concave, and are provided at positions that are different from the engaging convex portions 29a to 29d by a predetermined angle around the central axis O of the lid 20. The lid 20B is configured to be stackable on another lid 20A having the same shape as the lid 20B in the upper (height) direction. The engaging concave portions 27a to 27d of the lid 20B are configured to fit into the engaging convex portions 29a to 29d of the other lid 20A when the lid 20B is stacked at an angle rotated by a predetermined angle (90°) around the central axis O of the lid 20B relative to the other lid 20A.

[0075] According to this structure, the fitting protrusions 29a to 29d and the fitting recesses 27a to 27d are provided on the outer peripheral side of the covers 20A and 20B and at positions separated around the central axis O of the covers 20A and 20B. Thus, the plurality of covers 20A and 20B can be stacked more stably.

[0076] When accommodating food in a plurality of container bodies 30, the work can be performed while the plurality of lids 20A and 20B are stacked, thereby ensuring a larger work space.

[0077] (2-2) The gripping portion 22 passes through the central axis O and its long side direction extends along the radial direction of the circular top surface 21a, and the gripping portion 22 is gripped by the user from the width direction (short side direction). Two engaging protrusions 29a to 29d are formed in a convex shape at both ends of the long side direction of the gripping portion 22. The engaging recesses 27a to 27d are arranged at positions that are 90° different from the engaging protrusions 29a to 29d as a predetermined angle around the central axis O of the cover 20, and are formed in a concave shape on the wall portion 25b that is erected in a wall shape toward the bottom so as to surround the entire circumference of the cover lower surface 25a on the outer peripheral side.

[0078] According to this structure, the covers 20 can be stacked in directions that differ from each other by 90 degrees.

[0079] In addition, the fitting convex parts 29a, 29b and the fitting convex parts 29d, 29c, and the fitting concave parts 27a, 27b and 27d, 27c are respectively provided at two locations on the diagonal line passing through the central axis O. Therefore, when the cover 20B is stacked on the cover 20A, it is possible to stack the cover 20B regardless of whether the cover 20B is rotated 90° or 270° around the central axis O relative to the cover 20A.

[0080] (2-3) The cover 20 has a plurality of vertical legs 23a, 23b or 23c, 23d, which are located outside the respective ends of the grip 22 in the longitudinal direction and are convex on the peripheral wall 21b of the cover 20, extending in the vertical (height) direction of the cover 20 from the peripheral wall 21b to the range above the top surface 21a, and contacting the table T at mutually separated positions in a manner that the cover 20 is self-supporting in the longitudinal direction of the table T. The vertical legs 23a to 23d and the engaging protrusions 29a to 29d are provided in the same number, respectively, and are formed continuously on the same plane.

[0081] According to this configuration, the vertical leg portions 23a to 23d and the fitting protrusions 29a to 29d can be formed continuously, and a simpler configuration can be achieved.

[0082] (2-4) The long side direction of the gripping portion 221 extends along the radial direction of the top surface 21a, and the gripping portion 221 is gripped by the user from the width direction (short side direction). The cover 20 has: gaps 29e, 29f, respectively formed at both ends of the long side direction of the gripping portion 22; and locking protrusions 27e, 27f, formed on the wall portion 25b erected on the lower surface 25a of the cover. The locking protrusions 27e, 27f of the cover 20B are configured to fit into the gaps 29e, 29f of the other cover 20A when the cover 20B is stacked relative to the other cover 20A at an angle rotated by a predetermined angle around the central axis O of the cover 20B.

[0083] According to this structure, the covers 20A and 20B can be stacked stably by fitting the gaps 29e and 29f with the locking projections 27e and 27f.

[0084] In addition, the present disclosure is not limited to the above-mentioned embodiments and drawings. Changes (including deletion of constituent elements) can be appropriately added within the scope of not changing the gist of the present disclosure. An example of the modification is described below.

[0085] (Variation Example)

[0086] In the above embodiment, the container body 30 is in the shape of a bottomed cylindrical tube, but the present invention is not limited thereto and may be formed in the shape of a bottomed square tube. In this case, the cover 20 is in the shape of a substantially rectangular plate having four sides.

[0087] In the above embodiment, the outer cover portion 21 and the inner cover portion 25 are formed separately, but they may be formed integrally.

[0088] In the above-described embodiment, the heat insulating material 26 of the cover 20 may be omitted.

[0089] In the above embodiment, the engaging convex parts 29a, 29b and the engaging convex parts 29d, 29c, and the engaging concave parts 27a, 27b and 27d, 27c are respectively provided at two locations on the diagonal line. Therefore, the cover 20B is configured to be stacked on the upper surface of the cover 20A in a state rotated 90° around the central axis O of the cover 20B relative to the cover 20A. However, the engaging convex parts 29a, 29b and the engaging convex parts 29d, 29c, the engaging concave parts 27a, 27b and the engaging concave parts 27d, 27c may be respectively provided at two or more locations, and in this case, the covers 20A and 20B may be configured to be stacked at an angle other than 90°. For example, if three positions are provided, the laminate can be stacked in a state rotated by 60°, if four positions are provided, the laminate can be stacked in a state rotated by 45°, and if six positions are provided, the laminate can be stacked in a state rotated by 30°. The selection can be made appropriately. In this case, the fitting recesses 27a and 27b may be arranged at positions that differ from the fitting protrusions 29a and 29b at an angle other than 90° around the central axis O of the cover 20, for example, 10° to 80°.

[0090] In the above embodiment, two longitudinal legs are provided in two groups (a combination of longitudinal legs 23a and 23b and a combination of longitudinal legs 23c and 23d), but two longitudinal legs may be provided in only one group, or in three or more groups. In addition, one group is composed of two longitudinal legs, but one group may be composed of three or more longitudinal legs.

[0091] In the above embodiment, two fitting convex parts are provided in two groups (a combination of fitting convex parts 29a and 29b and a combination of fitting convex parts 29c and 29d), but two fitting convex parts may be provided in only one group, or in three or more groups. Similarly, two corresponding fitting concave parts may be provided in only one group, or in three or more groups.

[0092] Furthermore, in the above embodiment, two fitting protrusions 29a to 29d are provided at each end of the grip portion 22, but one fitting protrusion may be provided at each end of the grip portion 22, or three or more fitting protrusions may be provided at each end of the grip portion 22.

[0093] In the above-described embodiment, the fitting protrusions 29a to 29d are formed continuously with the vertically placed leg portions 23a to 23d, but may be formed discontinuously at separate positions.

[0094] In the above embodiment, the vertical legs 23a to 23d are also formed from the peripheral wall 21b of the cover 20 to the upper direction of the top surface 21a, but the present invention is not limited thereto and may be formed only in the vertical direction of the peripheral wall 21b of the cover 20.

[0095] In the above embodiment, the vertical legs 23a to 23d are in contact with the table top T at two points P1 and P2, but they may be in contact at three or more points, or may be in line contact or surface contact. In addition, the vertical legs 23a to 23d do not need to be of the same shape, and for example, the vertical legs 23a may be in contact with the table top T at two points (P1, P2) and the vertical legs 23b may be in contact with the table top T at one point (P3), for a total of three points (P1, P2, P3). Thus, the contact portion 23s can be in contact with the table top T at a total of three points, and the cover 20 can be vertically and stably self-supporting.

[0096] In the above embodiment, the peripheral wall 21b of the cover 20 may be partially formed into a flat surface instead of the vertical legs 23a to 23d, and the cover 20 may be self-standing by contacting the surface of the table top T with the flat surface as a self-standing contact portion.

[0097] In the above embodiment, the convex and concave of the fitting convex parts 29a to 29d and the fitting concave parts 27a to 27d may be reversed. In this case, a concave groove may be formed on the fitting convex parts 29a to 29d of the cover 20A, and a convex shape may be formed on the wall part 25b of the cover 20B instead of the fitting concave parts 27a to 27d, and the convex shape may be fitted into the groove, so that the covers 20A and 20B are stacked.

[0098] In the above embodiment, the grip portion 22 passes through the central axis O and has a substantially rectangular parallelepiped shape along the radial direction of the circular top surface 21 a , but the shape of the grip portion 22 can be changed as appropriate.

[0099] In the above embodiment, the cover 20 is inclined relative to the vertical direction of the table top T when standing vertically, but may be perpendicular to the table top T without being inclined.

[0100] In the above embodiment, the exposure portions 24a and 24b extend parallel to the central axis O, but may be inclined so as to approach the central axis O as they move from the cover lower surface 25a toward the front ends of the exposure portions 24a and 24b.

[0101] In the above embodiment, the exposure portions 24a and 24b are plate-shaped, but the present invention is not limited thereto and may have a concave shape for accumulating water.

[0102] In the above-described embodiment, the inclined portion 25d of the wall portion 25b may be omitted and the height of the wall portion 25b may be formed to be constant.

[0103] The steep slope surface 25c of the cover lower surface 25a may be omitted. In addition, the cover lower surface 25a, the top surface 21a, or the upper surface of the grip portion 22 may be formed by a flat surface.

[0104] The material of the cover 20 is not limited to resin, and may be formed of metal or wood.

[0105] Likewise, the material of the container body 30 is not limited to metal, and may be formed of resin or wood.

[0106] In the above-mentioned embodiment, any one of the vertical leg portions 23a and 23b and the vertical leg portions 23c and 23d may be omitted. In addition, all of the vertical leg portions 23a to 23d may be omitted.

[0107] In the above-described embodiment, one of the exposure portions 24 a and 24 b or both of the exposure portions 24 a and 24 b may be omitted.

[0108] In the above-described embodiment, the fitting protrusions 29 a to 29 d and the fitting recesses 27 a to 27 d may be omitted.

[0109] In addition, the present invention is not limited to the above-mentioned embodiments, and various changes can be made within the scope of each technical solution. That is, embodiments obtained by combining technical means appropriately changed within the scope of the technical solution are also included in the technical scope of the present invention.
