Description

Technical Field

[0001] The invention relates to a cover unit and a container with a cover. Background Art

[0002] Conventionally, there is a container with a lid including a lid unit detachably attached to a container body having an upper opening.

[0003] In addition, in the cover unit, there is a cover unit comprising: a cover body, which closes the upper opening of the container body and is provided with an opening at the upper part; a mouth forming component, which is installed around the opening of the cover body and is provided with a liquid through hole connected to the inner side of the container body; and a mouth disassembly mechanism, which detachably installs the mouth forming component around the opening of the cover body (for example, refer to the following patent document 1).

[0004] The mouth disassembly mechanism comprises a locking member slidably mounted on the cover body, and a force applying member that applies force to one side of the locking member in the sliding direction. In the mouth disassembly mechanism, the locking member is slid toward the other side in the sliding direction in a manner that overcomes the force of the force applying member, thereby releasing the locking state of the mouth forming member relative to the cover body. Thus, the mouth forming member can be removed relative to the periphery of the opening of the cover body.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2015-013675

[0006] However, in the above-mentioned conventional cover unit, when the cover unit is installed on the container body, if the locking part is slid incorrectly, the locking state of the mouth forming part relative to the cover body is released, sometimes causing the cover body to fall off from the container body.

[0007] That is, in the conventional port attaching and detaching mechanism, a locking mechanism for preventing the sliding of the locking member is not provided in response to the erroneous sliding operation of the locking member, and thus the usability is not necessarily good.

[0008] On the other hand, when the above-mentioned locking mechanism is added, there are also problems such as an increase in the number of components, a complicated structure, and an increase in the size of the product. Summary of the invention

[0055] like Figure 1 to Figure 6 As shown in FIG. 1 , a container 100 with a lid according to the present embodiment includes a lid unit 1 according to the present embodiment and a container body 2 to which the lid unit 1 is detachably mounted.

[0056] The container with a lid 100 is a beverage container that can keep a beverage (liquid) contained in the container body 2 cold (or warm) by using the container body 2 having a vacuum heat-insulating structure.

[0057] Specifically, the container body 2 is composed of a double-layer container, which has an outer container 3 with a bottom cylindrical shape, for example, made of stainless steel, and an inner container 4, and the peripheries of the opening edges of each other are joined while the inner container 4 is accommodated inside the outer container 3.

[0058] 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 exhaust holes provided on the bottom surface of the outer container 3 in a chamber decompressed (evacuated) to a high vacuum.

[0059] The container body 2 has a substantially circular bottom 2a, a barrel portion 2b substantially cylindrically rising from the outer periphery of the bottom 2a, and a substantially cylindrical neck portion 2c having a reduced diameter at the upper side of the barrel portion 2b.

[0060] The upper end of the neck portion 2c is opened in a circular shape as the upper opening 2d of the container body 2. In addition, the inner circumference of the neck portion 2c (the upper side of the barrel portion 2b) is reduced in diameter compared with the inner circumference of the barrel portion 2b. In addition, an annular extension portion 6 is provided protrudingly over the entire circumference of the lower portion of the inner circumference of the neck portion 2c (below the reduced diameter portion on the upper side of the barrel portion 2b).

[0061] In addition, a shoulder member 7 is installed all around the lower part of the neck opening 2c on the upper side of the barrel 2b. The shoulder member 7 is composed of, for example, a cylindrical resin member, and is embedded in the stepped portion 2e formed by reducing the diameter on the upper side of the barrel 2b in a manner that is substantially coplanar with the outer peripheral surface of the barrel 2b.

[0062] The lidded container 100 of the present embodiment has a generally cylindrical appearance as a whole, but the appearance of the lidded container 100 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 may be painted, printed, etc.

[0063] The cover unit 1 of this embodiment comprises: a cover body 8, which closes the upper opening 2d of the above-mentioned container body 2; a cover body 10, which is rotatably mounted on the cover body 8 via a first hinge part 9; and a handle part 12, which is rotatably mounted on the cover body 8 via a second hinge part 11.

[0064] In addition, in the following description, the side on which the cover body 10 is installed on the cover main body 8 via the first hinge portion 9 is set as the "rear side (back side)" of the cover unit 1 (container with cover 100), and the opposite side is set as the "front side (front side)" of the cover unit 1 (container with cover 100), and the direction connecting them is set as the front-to-back direction for description.

[0065] In addition, Figure 1 In the description, the side where the cover 10 is located relative to the container body 2 is set as the "upper side", the direction where the container body 2 is located relative to the cover 10 is set as the "lower side", and the direction connecting them is set as the up-down direction. In addition, the direction perpendicular to the up-down direction is set as the radial direction, and the direction perpendicular to the front-back direction in the radial direction is set as the left-right direction for description.

[0066] like Figure 2 to Figure 6 As shown, the cap body 8 includes an outer cylinder member 13 and a port forming member 14 made of, for example, a heat-resistant resin.

[0067] The outer tube member 13 includes a peripheral wall portion 13a formed in a substantially cylindrical shape in continuity with the barrel portion 2b of the container body 2, and an upper wall portion 13c having an opening 13b or a through hole formed at the upper portion of the peripheral wall portion 13a and having a reduced diameter compared to the peripheral wall portion 13a.

[0068] The outer cylinder member 13 (cap body 8) is detachably mounted on the neck portion 2c of the container body 2 by screwing. Therefore, a first external thread portion 15 is provided on the outer peripheral surface of the neck portion 2c (the upper side of the cylinder portion 2b). On the other hand, a first internal thread portion 16 screwed with the first external thread portion 15 is provided on the inner peripheral surface of the peripheral wall portion 13a of the outer cylinder member 13 (cap body 8).

[0069] like Figures 4 to 8 As shown, the port forming member 14 includes an upper port forming portion 14 a forming the upper side of the opening 13 b of the outer tube member 13 and a lower port forming portion 14 b forming the lower side of the opening 13 b of the outer tube member 13 .

[0070] The upper port forming portion 14a has a nozzle portion 17 protruding upward in a substantially cylindrical shape. A circular liquid passage 17a communicating with the inside of the container body 2 is provided at the front end of the nozzle portion 17 as a drinking port or a pouring port.

[0071] That is, when the cap body 8 is mounted on the neck portion 2c of the container body 2, it closes the upper opening 2d of the container body 2 and connects the inside and outside of the container body 2 via the nozzle 17 (liquid passage 17a).

[0072] The lower port forming portion 14 b is a portion that is inserted into the inner side of the container body 2 from the upper opening portion 2 d of the container body 2 , and is provided so as to protrude in a substantially cylindrical shape from the lower side of the upper port forming portion 14 a .

[0073] The opening forming member 14 is formed by Figures 4 to 15 The port attaching and detaching mechanism 18 shown is detachably mounted around the opening 13 b of the outer cylinder member 13 .

[0074] Specifically, the mouth disassembly and assembly mechanism 18 comprises: a locking part 19, which is slidably mounted on the outer tube part 13 (cover body 8) in the front-to-rear direction; a force-applying part 20, which applies force to the locking part 19 on one side (front side) in the sliding direction; a first locking part 21, which is located on the side (front side) opposite to the side of the mouth forming part 14 opposite to the locking part 19; a second locking part 22, which is located on the side (rear side) of the mouth forming part 14 opposite to the locking part 19; a first locked part 23, which is located on the front side around the opening part 13b of the outer tube part 13 (cover body 8); and a second locked part 24, which is located on one side (front side) in the sliding direction of the locking part 19.

[0075] like Figure 7 to Figure 9 , Fig.10 (A) Fig.10 As shown in (B), the lock member 19 is made of, for example, a heat-resistant resin, and includes an operating portion 19a, a cover portion 19b, a spring receiving portion 19c, a pair of fitting portions 19d, and a pair of anti-detachment portions 19e.

[0076] The operation portion 19a is located on the upper surface side of the lock member 19 and has a recessed shape for facilitating a sliding operation of the lock member 19 with a finger. The operation portion 19a is not limited to such a shape and can be modified as appropriate.

[0077] On the other hand, a cutout recess 13 d is provided on the upper surface (upper wall portion 13 c of outer cylinder member 13 ) side of the cap body 8 , and the lock member 19 is accommodated in the cutout recess 13 d .

[0078] The cutout recess 13d is located on the side of the first hinge portion 9 (the rear side of the cover body 8) around the opening portion 13b of the upper wall portion 13c (cover body 8) and is cut out along the sliding direction of the locking member 19 (the front-rear direction of the cover body 8).

[0079] The locking member 19 is located inside the cutout recess 13 d , and the operating portion 19 a is provided to face the upper surface side of the cover body 8 .

[0080] In addition, a step portion 13e is provided on the upper surface (upper wall portion 13c of outer cylinder member 13) side of the cover body 8, and the step portion 13e is formed by recessing the periphery of the opening portion 13b of the upper wall portion 13c (cover body 8) toward the side opposite to the first hinge portion 9 (the front side of the cover body 8). Thus, the cutout recess 13d is provided by cutting out a part of the step portion 13e (the rear side of the cover body 8).

[0081] In the cover detaching mechanism 18, the operating portion 19a of the locking member 19 facing outward from the cutout recess 13d is arranged to be inclined upward along the inclination of the step portion 13e toward the rear side of the cover body 8. Thus, it is easy to slide the operating portion 19a of the locking member 19 facing outward from the cutout recess 13d toward the other side (rear side) of the sliding direction with a finger.

[0082] In addition, if Figure 7 As shown, the upper surface side of the locking member 19 is substantially coplanar with the upper surface side of the cover body 8 formed by the upper wall portion 13c and the step portion 13e of the outer cylinder member 13. As a result, even when the cover body 10 is in the closed position, the cover body 10 and the locking member 19 do not interfere with each other, and the cover unit 1 can be made into a space-saving and simple structure. In addition, the operating portion 19a of the locking member 19 can be easily operated, and a beautiful appearance with a sense of unity is formed.

[0083] The cover portion 19 b is located on the lower surface side of the locking member 19 , is exposed on the lower surface side so as to cover the inner lower surface of the cover body 8 including the urging member 20 (the lower surface of the upper wall portion 13 c ), and is formed in a substantially rectangular flat plate shape.

[0084] The spring receiving portion 19c is composed of a protrusion that protrudes rearward from the center portion of the back side of the operating portion 19a.

[0085] The pair of fitting portions 19d are located on both sides of the lock member 19 in the left-right direction, and are formed of guide grooves formed concavely inward in the left-right direction between the operation portion 19a and the cover portion 19b over the front-rear direction.

[0086] A pair of anti-detachment parts 19e are located on both sides in the left-right direction sandwiching the spring receiving part 19c, protrude rearward from the back side of the operating part 19a, and have front ends composed of hook parts protruding outward.

[0087] On the other hand, Figure 7 to Figure 9 , Fig.11 , Fig.12 As shown, the cap body 8 has a spring receiving portion 25a, a pair of guide portions 25b, and a pair of stopper portions 25c on the lower surface inside the outer cylinder member 13 (the lower surface of the upper wall portion 13c).

[0088] The spring receiving portion 25a is located at the front end side of a portion protruding forward from the rear center portion of the cutout recess 13d, and is composed of a pair of protrusions protruding forward from both sides in the left-right direction.

[0089] The pair of guide portions 25b are located on both sides of the cutout recess 13d in the left-right direction, and are formed of guide protrusions that extend from the lower end of the cutout recess 13d in the front-rear direction and protrude inward in the left-right direction.

[0090] The locking member 19 is mounted inside the cutout recess 13d so as to be slidable in the front-rear direction by fitting the pair of guide portions 25b in the pair of fitting portions 19d.

[0091] The pair of stopper portions 25c are located on both sides of the cutout recess 13d in the left-right direction, and are constituted by claw portions that protrude inward from the side surface on the rear side of the cutout recess 13d.

[0092] The lock member 19 is prevented from falling off from the inside of the cutout recess 13d by the pair of anti-falling portions 19e coming into contact with the pair of stopper portions 25c on one side (front side) in the sliding direction.

[0093] like Fig.11 , Fig.12 As shown, the urging member 20 is composed of, for example, a coil spring, and is arranged between a spring support portion 25a on one side of the outer tube member 13 (cover body 8) and a spring support portion 19c on the other side of the locking member 19, and always urges the locking member 19 to one side (front side).

[0094] The locking member 19 is urged toward one side (front side) in the sliding direction by the urging member 20 , so that the pair of anti-detachment portions 19 e abut against the pair of stopper portions 25 c , thereby preventing the locking member 19 from detaching toward the front side from the inside of the cutout recess 13 d .

[0095] On the other hand, the lock member 19 is pushed in against the urging force of the urging member 20 , and can be slid toward the other side (rear side) in the sliding direction, that is, toward the first hinge portion 9 side.

[0096] In addition, as for the urging member 20 , an elastic member such as rubber or elastomer may be used instead of the spring member such as the coil spring described above.

[0097] like Figure 13 to Figure 15 As shown, the first locking portion 21 is located at the boundary between the upper port forming portion 14 a and the lower port forming portion 14 b of the port forming member 14 , and is composed of a claw portion protruding forward from the front side of the port forming member 14 .

[0098] The second locking portion 22 is located at a boundary between the upper port forming portion 14 a and the lower port forming portion 14 b of the port forming member 14 , and is composed of a claw portion that protrudes rearward from the rear side of the port forming member 14 .

[0099] The first locked portion 23 is formed by a stepped portion formed by recessing a portion of the upper wall portion 13 c (stepped portion 13 e ) along the front side of the opening 13 b .

[0100] The second locked portion 24 is composed of a claw portion that protrudes forward from below the operation portion 19 a on the front side of the lock member 19 .

[0101] In the mouth disassembly and assembly mechanism 18, first, as Fig.15 As shown, the first locking portion 21 is locked to the first locked portion 23 while the upper port forming portion 14a of the port forming member 14 is fitted into the inner side of the opening portion 13b of the outer tube member 13 (cap body 8) from the bottom.

[0102] Next, the rear side of the port forming member 14 is pushed upward, whereby the second locking portion 22 moves upward while pressing the locking member 19 to the other side (rear side) in the sliding direction against the urging force of the urging member 20 .

[0103] Next, if Fig.13 As shown, the locking member 19 slides toward the locking position on one side (front side) of the sliding direction by the urging force of the urging member 20, thereby urging the second locking portion 22 to the second locked portion 24. Thus, the port forming member 14 can be mounted around the opening 13b of the outer tube member 13 (cover body 8).

[0104] On the other hand, in the mouth disassembly mechanism 18, from the Fig.13 As shown in the state, Fig.14 As shown, the lock member 19 is slidably operated from a lock position on one side (front side) in the sliding direction toward an unlock position on the other side (rear side) in the sliding direction against the urging force of the urging member 20 .

[0105] Therefore, if Fig.15 As shown, the locking state of the port forming member 14 relative to the outer tube member 13 (cover body 8) is released, and the port forming member 14 can be removed downward relative to the periphery of the opening portion 13b of the outer tube member 13 (cover body 8).

[0106] like Figure 4 and Figure 5 As shown, the water stop packing 26 is detachably mounted on the port forming member 14 .

[0107] The waterproof packing 26 is an annular sealing member for sealing the extension portion 6 (container body 2) and the port forming member 14 (cap body 8), and is made of heat-resistant rubber such as silicone rubber or an elastic member such as an elastomer.

[0108] The water stop packing 26 is fitted to the outer peripheral portion of the lower flange portion 14 c provided on the outer peripheral portion of the lower end side of the lower port forming portion 14 b (port forming member 14 ).

[0109] Furthermore, two elastic flange portions 26 a are provided on the outer peripheral surface of the waterproof packing 26 so as to protrude over the entire circumference in the diameter expansion direction.

[0110] When the cover unit 1 is installed on the container body 2 in a manner to close the upper opening 2d, the water-stopping seal 26 becomes the lower side opening forming portion 14b (opening forming component 14) embedded in the inner side of the container body 2, so that the elastic flange portion 26a is elastically deformed while being tightly attached to the extension portion 6 throughout the entire circumference.

[0111] Thus, the space between the extension portion 6 (container body 2 ) and the port forming member 14 (lid body 8 ) can be sealed (waterproofed) via the water-stopping packing 26 .

[0112] On the other hand, the waterproof packing 26 can be removed from the lower flange portion 14c (the port forming member 14) by elastically deforming (stretching and extending) itself.

[0113] Thus, the waterproof packing 26 and the port forming member 14 can be cleaned separately, and the space between the waterproof packing 26 and the port forming member 14 can be kept clean.

[0114] In addition, the waterproof packing 26 is not necessarily limited to the above-mentioned shape. For example, the number of the elastic flanges 26a is not limited to the above-mentioned two, but can be set to one or more than three. In addition, the waterproof packing 26 is not necessarily limited to the structure provided with the above-mentioned elastic flange 26a, and its shape and the like can be appropriately changed.

[0115] The waterproof packing 26 may be integrally formed so as to be non-detachable from the port forming member 14. In this case, liquid and dirt can be prevented from entering between the waterproof packing 26 and the port forming member 14, and hygiene can be maintained.

[0116] like Figure 1 to Figure 5 As shown, the cover body 10 includes a rotating member 27 and a cover member 28 made of, for example, a heat-resistant resin.

[0117] The rotating member 27 is configured such that its base end side is rotatably mounted via the first hinge portion 9 and has a circular annular ring portion 27a at its front end side. The ring portion 27a is formed so that a portion of the inner peripheral surface (two locations in the front-rear direction in this embodiment) has a concave cross-section.

[0118] The cover member 28 has a peripheral wall portion 28a formed in a substantially cylindrical shape, a top wall portion 28b covering the upper portion of the peripheral wall portion 28a, and a convex ring portion 28c intermittently protruding from the outer peripheral portion of the lower end side of the peripheral wall portion 28a over the entire circumference. The cover member 28 is fixed in a state where the convex ring portion 28c is inserted into the inner side of the ring portion 27a, thereby being mounted to be freely rotatable around its central axis.

[0119] In addition, the width of the convex shape of the convex ring portion 28c in the vertical direction is smaller than the width of the concave shape of the cross section of the ring portion 27a in the vertical direction, so that the cover member 28 can slide in the vertical direction relative to the rotating member 27. In addition, the cover member 28 can move with respect to the ring portion 27a (rotating member 27) so that the lower end side is slightly inclined toward the entire circumferential direction.

[0120] The cap member 28 is detachably mounted on the nozzle portion 17 by screwing, thereby opening and closing the liquid passage 17a of the nozzle portion 17. Therefore, a second internal thread portion 29 is provided on the inner peripheral surface of the peripheral wall portion 28a (cap member 28). On the other hand, a second external thread portion 30 screwed with the second internal thread portion 29 is provided on the outer peripheral surface of the nozzle portion 17.

[0121] In addition, as described above, the convex ring portion 28c of the cover member 28 is locked inside the ring portion 27a of the rotating member 27. Therefore, when the cover member 28 is removed from the nozzle portion 17, the rotating member 27 can also follow the movement of the cover member 28. That is, it is possible to switch Figure 3 , 5 The open position shown, Figure 1 , 2 , the closed position shown in 4.

[0122] As described above, the cover member 28 can slide in the vertical direction relative to the rotating member 27, and the lower end side of the cover member 28 can be moved in a manner slightly inclined toward the entire circumferential direction. Therefore, when the cover body 10 is in the closed position and the second internal thread portion 29 and the second external thread portion 30 are screwed together, the cover member 28 is rotated in a horizontal position and can be screwed together smoothly without paying attention to the rotating member 27.

[0123] In the cover unit 1 of this embodiment, as Figure 1 and Figure 2 As shown, in a state where the cover member 28 (cover body 10 ) closes the liquid passage port 17 a of the nozzle portion 17 , the rotation member 27 is in a state where the operation portion 19 a of the lock member 19 is covered.

[0124] Therefore, when the cap member 28 (cap body 10) closes the liquid passage 17a of the nozzle portion 17, the locking member 19 cannot be operated, and the port forming member 14 does not fall off from the outer tube member 13. As a result, the port forming member 14 does not fall off accidentally, which is more secure.

[0125] like Figure 1 to Figure 5 , Fig.16 and Fig.17 As shown in (A) and (B) of FIG. 1 , the cover packing 31 is detachably mounted on the cover body 10 .

[0126] The cap packing 31 is a plug-shaped sealing member for sealing the front end side (liquid passage 17a) of the nozzle portion 17. The cap packing 31 is made of an elastic member, and the same material as the waterproof packing 26 can be used for the elastic member.

[0127] The cover packing 31 includes a substantially cylindrical shaft portion 31 a , a plug portion 31 b protruding from the lower end of the shaft portion 31 a over the entire circumference in the direction of diameter expansion, and a protrusion 31 c protruding downward from the center of the plug portion 31 b .

[0128] On the other hand, the cover member 28 (cover body 10) has a hole 28d that penetrates the center of the top wall 28b. In addition, a circular convex portion 28e is provided at the lower end side of the hole 28d, and the circular convex portion 28e protrudes downward from the top wall 28b over the entire circumference of the hole 28d.

[0129] The end side of the shaft portion 31a is expanded in diameter over the entire circumference. In addition, a reduced diameter portion 28f having the most reduced diameter is provided in the middle of the upper side of the hole portion 28d.

[0130] The cover packing 31 is attached to the inner lower surface of the cover member 28 (the lower surface of the top wall 28b) by inserting the shaft 31a into the hole 28d from below so that the enlarged diameter portion of the shaft 31a fits into the reduced diameter portion 28f of the hole 28d.

[0131] In addition, in order to insert the shaft portion 31a into the hole portion 28d, the shaft portion 31a needs to have a certain degree of rigidity. Therefore, the cover packing 31 is preferably a solid component without a cavity inside the shaft portion 31a. On the other hand, the cover packing 31 can also reduce the material and achieve weight reduction by setting the interior of the shaft portion 31a as a cavity. In this case, it is necessary to select a material with appropriate hardness to ensure rigidity.

[0132] Furthermore, the cap packing 31 is mounted on the lower surface of the inner side of the cap member 28 through the hole 28d, so that even when the cap member 28 (cap body 10) closes the liquid passage 17a of the nozzle portion 17, the top surface of the shaft portion 31a can be visually confirmed from the outside on the substantially same plane as the top wall portion 28b. Thus, it is easy to confirm that the cap packing 31 has not been forgotten to be installed.

[0133] The protrusion 31c can enter the inside of the nozzle 17 from the liquid passage 17a, and protrudes downward to such an extent that it can be pinched with fingers. In addition, the protrusion 31c is formed in a flat plate shape to facilitate pinching with fingers.

[0134] The front end (lower end) of the protrusion 31c is provided with a flange 31d on the long side of the flat plate shape so as to protrude in the diameter expansion direction. The flange 31d functions as a non-slip portion and a finger hook portion when the protrusion 31c is pinched with fingers.

[0135] The lower end of the protrusion 31c is located above the lower end of the cover member 28 and below the central axis of the first hinge 9. If the protrusion 31c is too long, it is difficult to introduce it into the nozzle 17 when the cover 10 is in the closed position, and if it is too short, it is difficult to hold.

[0136] In the cap unit 1 of the present embodiment, when the cap member 28 (cap body 10 ) closes the liquid passage 17 a of the nozzle 17 , the plug 31 b is in close contact with the periphery of the front end side of the nozzle 17 .

[0137] Here, the plug portion 31b is formed into a hemispherical shape with a convex shape at the bottom, and has an upper rib 31e convexly arranged upward in a concentric circle on its upper side. When the cover packing 31 is installed on the lower surface of the inner side of the cover member 28 through the hole portion 28d, the circular convex portion 28e is inserted into the valley between the shaft portion 31a and the upper rib 31e.

[0138] Therefore, when the plug 31b is in close contact with the periphery of the front end side of the nozzle 17, the plug 31b is pressed from above by the circular protrusion 28e, and the upper end of the upper rib 31e abuts against the lower surface side of the top wall 28b.

[0139] Thus, the center side (protrusion 31c side) of the plug portion 31b is less likely to elastically deform upward, and only the outer peripheral side of the plug portion 31b abutting against the front end side of the nozzle portion 17 can be elastically deformed and bent.

[0140] Therefore, the actual bending length of the plug portion 31b is reduced, and since it is pressed from above by the circular protrusion 28e and from below by the front end side of the nozzle portion 17, it is more firmly in close contact with the periphery of the front end side of the nozzle portion 17.

[0141] Thus, the front end side (liquid passage 17 a ) of the nozzle portion 17 can be reliably sealed via the cap packing 31 .

[0142] On the other hand, in the cap unit 1 of the present embodiment, the cap packing 31 can be easily removed from the inner side of the cap member 28 (cap body 10 ) by pulling downward while pinching the protrusion 31 c .

[0143] In addition, in the cover unit 1 of the present embodiment, the cover packing 31 can be easily installed on the lower surface of the inner side (the lower surface of the top wall portion 28b) of the cover part 28 (cover body 10) by pressing upward from the lower surface side of the cover part 28 side while pinching the protrusion 31c of the above-mentioned cover packing 31.

[0144] Furthermore, since the cover packing 31 removed from the cover member 28 (cover body 10 ) can be washed separately from the cover member 28 (cover body 10 ), the space between the cover packing 31 and the cover member 28 (cover body 10 ) can be kept hygienic.

[0145] like Figure 1 to Figure 3 As shown, the handle member 12 is composed of a partially opened annular member and is rotatably mounted on the outer tube member 13 via a second hinge portion 11 provided on the side surface (peripheral wall portion 13a) on the rear side of the outer tube member 13 (cover body 8).

[0146] Thus, in the lidded container 100 including the lid unit 1 of the present embodiment, the container can be carried while holding the handle member 12 .

[0147] In the covered container 100 having the cover unit 1 of this embodiment having the above-described structure, the port detaching mechanism 18 is described in a state where the cover body 8 is mounted on the container body 2 and the cover member 28 (cover body 10) opens the liquid passage 17a of the nozzle portion 17.

[0148] like Figure 6As shown, when the cap body 8 is mounted on the container body 2, if the locking member 19 (mouth detaching mechanism 18) is slid toward the unlocking position located on the other side (rear side) of the sliding direction, a part of the locking member 19, that is, the rear end of the cover portion 19b is brought into contact with the inner surface of the neck opening portion 2c of the container body 2. At this time, before the locking state of the second locking portion 22 and the second locked portion 24 is released, the rear end of the cover portion 19b is brought into contact with the inner surface of the neck opening portion 2c of the container body 2.

[0149] Thus, the locking member 19 can be prevented from sliding against an erroneous sliding operation, and the locking state of the port forming member 14 relative to the outer tube member 13 (cover body 8) can be prevented from being released, thereby preventing the port forming member 14 from falling off.

[0150] Furthermore, when the covered container 100 is dropped, the port forming member 14 can be prevented from falling off from the outer tube member 13 (cover body 8 ) due to an erroneous sliding operation of the locking member 19 caused by the impact of the drop.

[0151] In the cover unit 1 of the present embodiment, there is no need to separately provide a locking mechanism for preventing the locking member 19 from sliding. Therefore, the port attaching and detaching mechanism 18 can be formed into a space-saving and simple structure without increasing the number of components.

[0152] In addition, the cover portion 19b is exposed on the lower surface side in a manner covering the inner lower surface of the cap body 8 (the lower surface of the upper wall portion 13c), so that the internal structure of the port detachable mechanism 18 including the biasing member 20 cannot be visually observed from the outside, and the aesthetics are good.

[0153] As described above, in the lidded container 100 having the lid unit 1 of the present embodiment, the above-mentioned mouth disassembly mechanism 18 has a simple structure, and can prevent the locking member 19 from sliding in the event of an erroneous sliding operation, thereby further improving the ease of use.

[0154] In addition, the present invention is not necessarily limited to the above-mentioned embodiment, and various modifications can be added within the scope not departing from the gist of the present invention.

[0155] For example, in the above-mentioned embodiment, a cover unit 1 is illustrated which includes a mouth-forming component 14 having a nozzle portion 17 which forms the above-mentioned liquid passage port 17a. However, the mouth-forming component 14 is not limited to such a structure, and for example, a liquid passage port may be provided on the bottom surface of the mouth-forming component which forms a drinking port or an injection port.

[0156] In addition, in the above-mentioned embodiment, the cover component 28 (cover body 10) is illustrated as being freely installed and detachably mounted on the cover unit 1 of the above-mentioned nozzle portion 17 by screwing, but it is not limited to such a structure. For example, it can also be configured that the cover body for opening and closing the liquid port is freely installed on the cover body via a hinge portion, and has a cover locking mechanism for fixing the cover body relative to the cover body.

[0157] In addition, in the above-mentioned embodiment, the present invention is illustrated as being applied to a beverage container having a heat preservation / cooling function by means of a container body 2 having the above-mentioned vacuum insulation structure, but the present invention can be widely applied to a lidded container having a container body and a lid unit that is freely and detachably mounted on the container body.
