Description

TECHNICAL FIELD

[0001] The present application relates to a lid unit and a container with a lid. BACKGROUND

[0002] In the past, there has been a container with a lid unit (lid body) that is detachably attached to a container body having an upper opening. Among them, a lid unit with a straw is proposed, which has a lid body that closes an upper opening portion of the container body and is provided with a straw having flexibility protruding from the upper portion, a lid body that is rotatably attached to the lid body via a hinge portion, a lid locking mechanism that fixes the lid body with respect to the lid body, and a waterproof packing (sealing member) that seals between the container body and the lid body (for example, refer to Patent Document 1 below).

[0003] In a beverage container provided with such a lid unit, when the lid body is fixed with respect to the lid body by the lid locking mechanism, the straw is housed inside the lid body in a bent state. In addition, the protruding portion provided inside the lid body abuts against the straw, and the straw is crushed, thereby closing the liquid passage of the straw. On the other hand, by releasing the fixation of the lid body by the lid locking mechanism, the lid body is rotated in the opening direction, and at the same time, the straw is elastically restored from the bent state to the original state. Thereby, it is possible to drink the beverage in the container body through the straw.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2018-008714

[0005] However, in the above-described lid unit with a straw, when drinking the beverage in the container body through the straw, as the beverage in the container body decreases, the pressure in the container body becomes negative. At this time, by the first air hole provided in the upper portion of the lid body, the outside air is introduced into the inside of the container body. Thereby, the pressure in the container body is restored to atmospheric pressure, so it is possible to continue drinking the beverage in the container body through the straw.

[0006] On the other hand, in the state where the lid body is fixed to the lid body by the above-described lid locking mechanism, in order to prevent the beverage in the container body from leaking to the outside from the first air hole, by making the straw crushed by the protruding portion and the periphery of the first air hole in close contact, the first air hole is closed. However, if the straw is bent at a position deviating from the first air hole, it is often not possible to properly close the first air hole, resulting in leakage of the beverage from the first air hole.

[0007] In addition, when the fixation of the lid body by the lid locking mechanism is released, in order to prevent the residual liquid in the straw from flying to the outside, the air in the container body is released to the outside from the second air hole provided in the upper portion of the lid body (the pressure in the container is released to the outside).

[0008] In this case, it is required to reliably open the second vent hole before the straw elastically returns from the bent state to the original state. On the contrary, it is necessary to reliably close the second vent hole when the lid body is fixed to the lid main body by the lid locking mechanism.

[0009] Further, the second vent hole is constituted by a central hole provided to the cylindrical protruding portion of the waterproof packing. The waterproof packing is constituted by a ring-shaped elastic member, and is fitted to the inside of the lid main body in a state where the cylindrical protruding portion protrudes upward from the through hole provided to the upper portion of the lid main body.

[0010] In this case, it is necessary to preliminarily press the cylindrical protruding portion with respect to the through hole to fix the waterproof packing to an appropriate position on the inside of the lid main body. Further, if the press of the cylindrical protruding portion with respect to the through hole is insufficient, it is difficult to appropriately perform the opening and closing of the above-mentioned second vent hole. Further, this also becomes a cause of leakage of the beverage in the container main body to the outside.

[0011] Further, if the press of the cylindrical protruding portion with respect to the through hole is insufficient, when the lid main body is attached to the neck portion of the container main body by screwing, there is a possibility that the waterproof packing deviates from the appropriate position. SUMMARY

[0080] like Figures 1-4 As shown, the lidded container 100 of this embodiment is a beverage container that has a lid unit 1 with a straw and a container body 2 on which the lid unit 1 is detachably installed, and can drink beverages (liquids) in the container body 2 through a flexible straw 7 described later.

[0081] In addition, in the lidded container 100 of this embodiment, the beverage (contents) contained in the container body 2 can be kept cold (or warm) through the container body 2 having a vacuum insulation structure.

[0082] Specifically, the container body 2 is composed of a double-layered container having an outer container 3 of a bottomed cylindrical shape composed of, for example, stainless steel or the like and an inner container 4, and is joined to each other with the inner container 4 housed in the inner side of the outer container 3 in a state where the mouth portions thereof are joined to each other. Further, a vacuum heat insulating layer 5 is provided between the outer container 3 and the inner container 4. The vacuum heat insulating layer 5 can be formed, for example, by plugging an exhaust hole provided in the central portion of the bottom surface of the outer container 3 in a chamber reduced in pressure (vacuumized) to a high vacuum.

[0083] The container body 2 has a substantially circular bottom surface portion 2a, a cylindrical portion 2b standing in a substantially cylindrical shape from the outer periphery of the bottom surface portion 2a, and a substantially cylindrical neck portion 2c which is reduced in diameter at the upper portion side of the cylindrical portion 2b. Further, the upper end portion of the neck portion 2c is circularly opened as an upper opening portion 2d of the container body 2.

[0084] Further, in the capped container 100 of the present embodiment, the container body 2 has a substantially cylindrical appearance shape as a whole, but the appearance shape of the container body 2 is not particularly limited and can be appropriately changed depending on the size, appearance design, or the like. Further, the outer peripheral surface of the container body 2 can be subjected to painting, printing, or the like.

[0085] As shown in FIG. 1, the capped container 100 of the present embodiment is provided with a container body 2, a lid unit 1, and a lid lock mechanism 20. Figures 2-6 As shown in FIG. 1, the capped container 100 of the present embodiment is provided with a container body 2, a lid unit 1, and a lid lock mechanism 20.

[0086] Further, in the capped container 100 of the present embodiment, the side of the lid unit 1 on which the first hinge portion 8 is provided is referred to as the "rear side", and the side opposite to the side on which the first hinge portion 8 is provided is referred to as the "front side".

[0087] The lid body 6 is composed of, for example, a synthetic resin such as polypropylene. The lid body 6 has a peripheral wall portion 6a formed in a substantially cylindrical shape and an upper wall portion 6b which covers the upper surface of the peripheral wall portion 6a.

[0088] The lid body 6 is detachably attached to the neck portion 2c of the container body 2 by screwing. Therefore, an inner thread portion 12 is provided on the inner peripheral surface of the peripheral wall portion 6a. On the other hand, an outer thread portion 13 which is screwed with the inner thread portion 12 is provided on the outer peripheral surface of the neck portion 2c of the container body 2.

[0089] The lid body 6 has an attachment hole 14 which penetrates the substantially central portion of the upper wall portion 6b, and a fitting peripheral wall 15 which protrudes in a ring shape from the lower surface of the upper wall portion 6b in a manner of surrounding the periphery of the attachment hole 14.

[0090] The straw 7 is made of, for example, a rubber such as silicone rubber, an elastic member, and the like, and has a straw portion 7a formed in a tubular shape, a flange portion 7b provided at a middle portion in a length direction of the straw portion 7a, and a tube connecting portion 7c provided at a lower end portion of the straw portion 7a.

[0091] The straw 7 is attached to the lid main body 6 in a state where the straw portion 7a penetrates the attachment hole 14, and the flange portion 7b is fitted to the inside of the fitting peripheral wall 15, thereby being attached to the lid main body 6 in a detachable manner. The straw portion 7a is curved toward the front in a state where it protrudes from the upper portion of the lid main body 6.

[0092] The attachment hole 14 is formed in a shape that is anisotropic when viewed in plan view (elliptical in the present embodiment). Corresponding to the shape of the attachment hole 14, the base end portion of the straw portion 7a is formed in an elliptical shape when viewed in cross section. That is, when the straw portion 7a is attached to the attachment hole 14, the orientation of the straw portion 7a attached to the attachment hole 14 has directionality, thereby enabling the straw 7 to be positioned with respect to the lid main body 6. Further, the attachment hole 14 is not limited to the above-described elliptical shape, and can be any shape other than a circular shape, as long as the orientation of the straw portion 7a can be clearly attached.

[0093] On the other hand, the liquid passage of the straw portion 7a is formed in a circular shape when viewed in cross section. Thereby, the durability of the straw portion 7a that is housed inside the lid body 9 in a curved state to elastic deformation can be improved. In addition, the restoring force when the straw portion 7a elastically returns from the curved state to the original state and the elastic force to push up the lid body 9 can be improved.

[0094] The tube connecting portion 7c is connected to a suction tube 16 that sucks up the beverage housed in the container main body 2. The suction tube 16 extends in a cylindrical shape from the tube connecting portion 7c to the vicinity of the bottom of the container main body 2. Thereby, even in the case where the beverage in the container main body 2 becomes less, it is possible to drink to the end.

[0095] In addition, the lower end portion of the suction tube 16 can be appropriately changed to a shape where a part thereof is obliquely cut, a shape where it is cut in a wavy shape, or the like. Thereby, even in the case where the lower end portion of the suction tube 16 abuts against the inner bottom surface portion of the container main body 2, it is possible to prevent the beverage in the container main body 2 from becoming difficult to drink.

[0096] A waterproof packing 11 is detachably attached to the inside of the lid main body 6. The waterproof packing 11 is made of, for example, a ring-shaped elastic member (sealing member) such as a rubber such as silicone rubber, an elastomer, and the like, and is fitted between the peripheral wall portion 6a and the fitting peripheral wall 15. In addition, a gripping portion 11a for gripping at the time of attachment and detachment is provided protruding from the inner peripheral portion on the lower surface side of the waterproof packing 11.

[0097] When the lid body 6 is attached to the neck portion 2c of the container body 2, the waterproof packing 11 is brought into a state of being in close contact with the upper opening portion 2d (the upper end portion of the neck portion 2c) over the entire circumference, thereby making the container body 2 and the lid body 6 airtight.

[0098] On the other hand, the waterproof packing 11 can be removed from the inside of the lid body 6 in a state of being pinched by the holding portion 11a. Thus, the waterproof packing 11 and the lid body 6 can be washed separately, and the waterproof packing 11 and the lid body 6 can be kept hygienic.

[0099] The waterproof packing 11 has a first cylindrical protruding portion 18 provided with a first air hole 17 for introducing air from the outside into the inside of the container body 2, and a second cylindrical protruding portion 20 provided with a second air hole 19 for releasing air in the container body 2 to the outside (releasing pressure in the container body 2 to the outside).

[0100] The first cylindrical protruding portion 18 and the second cylindrical protruding portion 20 are constituted by a pair of cylindrical protruding portions formed in a substantially cylindrical shape. The pair of cylindrical protruding portions (the first cylindrical protruding portion 18 and the second cylindrical protruding portion 20) have the same shape as each other, and are provided protruding upward from positions symmetric to each other on the upper surface of the waterproof packing 11.

[0101] On the other hand, the lid body 6 has a first through hole 21 and a second through hole 22 that penetrate the upper wall portion 6b. The first through hole 21 is circular in cross section and is provided penetrating the upper wall portion 6b on the rear side of the mounting hole 14. The second through hole 22 is circular in cross section and is provided penetrating the upper wall portion 6b on the front side of the mounting hole 14. The first through hole 21, the mounting hole 14, and the second through hole 22 are arranged in the front-rear direction connecting the first hinge portion 8 and a lock member 28 described later.

[0102] The waterproof packing 11 is fitted to the inside of the lid body 6 (between the surrounding wall portion 6a and the fitting surrounding wall 15) in a state where one of the pair of cylindrical protruding portions, which is the first cylindrical protruding portion 18, is inserted from the first through hole 21 and protrudes upward, and the other of the pair of cylindrical protruding portions, which is the second cylindrical protruding portion 20, is inserted from the second through hole 22 and protrudes upward.

[0103] That is, the waterproof packing 11 can be inserted with the pair of cylindrical protruding portions, which are the first cylindrical protruding portion 18 and the second cylindrical protruding portion 20, being replaceably inserted with respect to the first through hole 21 and the second through hole 22. Thus, when the waterproof packing 11 is attached to the lid body 6, it is not necessary to pay attention to the attachment direction of the waterproof packing 11, and the attachment direction is not mistaken.

[0104] Further, the first and second cylindrical protruding portions 18 and 20 have a substantially pointed shape toward the tip end. Thus, the first and second cylindrical protruding portions 18 and 20 can be easily inserted with respect to the first and second through holes 21 and 22.

[0105] Further, the first and second cylindrical protruding portions 18 and 20 are provided at positions overlapping the upper opening portion 2d (the upper end portion of the neck portion 2c) of the container body 2 when viewed from above. Thus, even if the insertion of the first and second cylindrical protruding portions 18 and 20 with respect to the first and second through holes 21 and 22 is insufficient, the waterproof packing 11 in sliding contact with the upper opening portion 2d (the upper end portion of the neck portion 2c) is pushed upward, and the first and second cylindrical protruding portions 18 and 20 can be reliably inserted into the first and second through holes 21 and 22. As a result, leakage of the beverage from the inside of the container body 2 due to the lack of installation of the waterproof packing 11 can be prevented.

[0106] Further, the waterproof packing 11 has a plurality of (two in the present embodiment) positioning protrusions 23. The plurality of positioning protrusions 23 have the same shape as each other, and are provided protruding inward from positions symmetric to each other of the inner circumferential portion of the waterproof packing 11. Further, the plurality of positioning protrusions 23 are arranged in the left-right direction crossing (orthogonal to, in the present embodiment) the front-rear direction in which the pair of cylindrical protruding portions are arranged.

[0107] On the other hand, the lid body 6 has a plurality of (two in the present embodiment) positioning recesses 24 corresponding to the plurality of positioning protrusions 23, respectively. The plurality of positioning recesses 24 have the same shape and positions as the plurality of positioning protrusions 23, and have a shape in which the left and right sides of the fitting circumferential wall 15 are recessed inward.

[0108] The waterproof packing 11 is fitted to the inside of the lid body 6 (between the circumferential wall portion 6a and the fitting circumferential wall 15) in a state in which each of the positioning protrusions 23 is fitted into each of the positioning recesses 24. Thus, the waterproof packing 11 in sliding contact with the upper opening portion 2d (the upper end portion of the neck portion 2c) can be prevented from being twisted or displaced when the lid body 6 is installed on the neck portion 2c of the container body 2 by screwing.

[0109] Further, in the waterproof packing 11, each of the positioning protrusions 23 can be fitted into each of the positioning recesses 24 more replaceably in correspondence with the pair of cylindrical protruding portions being more replaceably inserted with respect to the first and second through holes 21 and 22 as the first and second cylindrical protruding portions 18 and 20 described above.

[0110] Further, in the present embodiment, a structure is adopted in which the positioning protrusion 23 is provided on the side of the waterproof packing 11 and the positioning recess 24 is provided on the side of the cover main body 6, but a structure opposite thereto, in which the positioning recess is provided on the side of the waterproof packing 11 and the positioning protrusion is provided on the side of the cover main body 6, can also be adopted.

[0111] The cover body 9 is composed of, for example, a synthetic resin such as polypropylene. The cover body 9 has a peripheral wall portion 9a formed in a substantially elliptical cylindrical shape and a top wall portion 9b that covers the top surface of the peripheral wall portion 9a. The cover body 9 is rotatably attached to the cover main body 6 via a first hinge portion 8 provided on the upper portion of the rear end side of the cover main body 6.

[0112] Further, a protrusion portion 25 and a first peg 26 are provided on the lower surface of the inside of the cover body 9. The protrusion portion 25 is provided protruding downward from the lower surface of the top wall portion 9b in a manner so as to abut against the suction pipe portion 7a. The first peg 26 is provided protruding downward from the lower surface of the top wall portion 9b in a manner so as to abut against the upper portion of the first cylindrical protrusion portion 18.

[0113] The cover locking mechanism 10 has a locking member 28 rotatably attached to the front side of the cover main body 6 via a second hinge portion 27, a force applying member 29 that applies a force to the locking member 28 toward one side in the direction of rotation, and a second peg 30 provided on the locking member 28.

[0114] The locking member 28 has an upper side arm portion 28a that extends upward from the second hinge portion 27, a lower side arm portion 28b that extends downward from the second hinge portion 27, and a rear side arm portion 28c that extends rearward from the upper side arm portion 28a.

[0115] The force applying member 29 is composed of, for example, an elastic member such as a coil spring. The force applying member 29 is disposed between the lower side arm portion 28b and the peripheral wall portion 6a in a compressed state. Further, the force applying member 29 can also be, for example, a rubber such as silicone rubber, an elastomer, or the like.

[0116] The second peg 30 is provided protruding downward from the tip side of the rear side arm portion 28c in a manner so as to abut against the upper portion of the second cylindrical protrusion portion 20.

[0117] The cover locking mechanism 10 has a first locking portion 31 provided on the side of the locking member 28 and a first locked portion 32 provided on the side of the cover body 9. The first locking portion 31 is composed of a hook portion that protrudes rearward from the tip portion of the upper side arm portion 28a. The first locked portion 32 is composed of a hook portion that protrudes forward from the lower end portion of the front side of the cover body 9.

[0118] In the cover locking mechanism 10, as Figure 2As shown, when the lid body 9 closes the upper portion of the lid main body 6, the first locking portion 31 on the side of the locking member 28 to which the urging member 29 applies a force is locked to the first locked portion 32 on the side of the lid body 9, whereby the lid body 9 is locked with respect to the lid main body 6.

[0119] The locking member 28 is rotatable between a locking position at which the first locking portion 31 is locked to the first locked portion 32 and a locking release position at which the locking state of the first locking portion 31 and the first locked portion 32 is released.

[0120] Therefore, in the lid locking mechanism 10, as shown, Figure 3 the lower side arm portion 28b side of the locking member 28 is pressed to overcome the force of the urging member 29, whereby the locking member 28 is rotated from the locking position to the locking release position, and the locking state of the first locking portion 31 and the first locked portion 32 is released.

[0121] Further, the lid locking mechanism 10 has a second locking portion 33 provided on the side of the locking member 28 and a second locked portion 34 provided on the side of the lid body 9. The second locking portion 33 is constituted by a hook portion protruding upward from the front end portion of the rear side arm portion 28c. The second locked portion 34 is constituted by a hook portion protruding rearward from the lower end portion of the front side of the lid body 9.

[0122] In the lid locking mechanism 10, as shown, Figure 2 from the state in which the lid body 9 is fixed with respect to the lid main body 6, as shown, Figure 3 the lower side arm portion 28b side of the locking member 28 is pressed to rotate the locking member 28 from the locking position to the locking release position, whereby the locking state of the first locking portion 31 and the first locked portion 32 is released, and then the second locking portion 33 on the side of the locking member 28 is locked to the second locked portion 34 on the side of the lid body 9. Thus, the rotation to one side (opening direction) of the lid body 9 is restricted.

[0123] On the other hand, in the lid locking mechanism 10, from the Figure 3 locking release state shown, as shown, Figure 4 the pressing of the locking member 28 is released, and the locking member 28 to which the urging member 29 applies a force is rotated from the locking release position to the locking position, whereby the locking state of the second locking portion 33 and the second locked portion 34 is released. Thus, the lid body 9 becomes rotatable (openable and closable).

[0124] On the other hand, in the lid locking mechanism 10, from Figure 4The illustrated state starts, the cover 9 is rotated in the direction of closing the upper portion of the cover main body 6 (the opening direction), thereby the first locking portion 31 is in sliding contact with the first locked portion 32, and the locking member 28 is rotated from the locking position to the locking release position against the force of the force applying member 29. In addition, the first locking portion 31 passes the first locked portion 32, thereby the locking member 28 is rotated from the locking release position to the locking position by the force of the force applying member 29. At this time, the first locking portion 31 is locked to the first locked portion 32. Thus, as Figure 2 illustrated, the cover 9 is closed to the upper portion of the cover main body 6, the cover 9 can be fixed relative to the cover main body 6.

[0125] In the cover unit 1 of the present embodiment having the above structure, as Figure 2 illustrated, when the cover 9 is closed to the upper portion of the cover main body 6, the suction pipe portion 7a (the suction pipe 7) is housed in the inside of the cover 9 in the bent state by the protrusion portion 25. In addition, the protrusion portion 25 in contact with the suction pipe portion 7a crushes the suction pipe portion 7a while closing the liquid passage of the suction pipe portion 7a.

[0126] In addition, in the state that the cover 9 is closed to the upper portion of the cover main body 6, the first peg 26 is in close contact with the periphery of the first vent hole 17, thereby the first vent hole 17 is in the closed state. In addition, the second peg 30 is in close contact with the periphery of the second vent hole 19, thereby the second vent hole 19 is in the closed state. Thus, in the state that the cover 9 is closed to the upper portion of the cover main body 6, the beverage in the container main body 2 can be prevented from leaking to the outside.

[0127] In the cover unit 1 of the present embodiment, from the Figure 2 illustrated closed state, as Figure 3 illustrated, the lower side arm portion 28b side of the locking member 28 is pressed, thereby the locking member 28 is rotated from the locking position to the locking release position, and the locking state of the first locking portion 31 to the first locked portion 32 is released.

[0128] At this time, the second locking portion 33 is locked to the second locked portion 34. In addition, the second peg 30 is separated from the periphery of the second vent hole 19, thereby the second vent hole 19 is in the open state.

[0129] In addition, by the rotation of the locking member 28 from the locking position to the locking release position, the second vent hole 19 is in the open state before the cover 9 is rotated in the opening direction. In addition, the second vent hole 19 is in the open state before the locking state of the first locking portion 31 to the first locked portion 32 is released.

[0130] Thus, air in the container body 2 can be released from the second vent hole 19 to the outside (pressure in the container body 2 is released to the outside), and then the straw portion 7a elastically recovers, so that residual liquid in the straw portion 7a (straw 7) can be prevented from flying out to the outside.

[0131] In the lid unit 1 of the present embodiment, from the Figure 3 As shown in FIG. 6, the pressing operation on the locking member 28 is released, and thus the locking member 28, which is pressed by the force applying member 29, rotates from the locking release position to the locking position, and the locking state of the second locking portion 33 and the second locked portion 34 is released. Figure 4

[0132] At this time, the straw portion 7a pushes up the lid body 9, and at the same time, elastically recovers from the bent state to the original state. In addition, as the straw portion 7a elastically recovers, the lid body 9 rotates in the opening direction. In addition, the first peg 26 is separated from the periphery of the first vent hole 17, and thus the first vent hole 17 becomes an open state.

[0133] On the other hand, the second peg 30 is in close contact with the periphery of the second vent hole 19, and thus the second vent hole 19 again becomes a closed state. Thus, leakage of the beverage in the container body 2 to the outside can be prevented, and the beverage in the container body 2 can be drunk by the straw portion 7a (straw 7) while sucking the beverage in the container body 2.

[0134] In addition, as the beverage in the container body 2 decreases, the pressure in the container body 2 becomes negative pressure. At this time, external air is introduced into the inside of the container body 2 through the first vent hole 17. Thus, the pressure in the container body 2 recovers to atmospheric pressure, and thus the beverage in the container body 2 can be continuously drunk by the straw portion 7a.

[0135] In the lid unit 1 of the present embodiment, the waterproof packing 11 is provided with the first cylindrical protruding portion 18 in which the first vent hole 17 is formed, and the second cylindrical protruding portion 20 in which the second vent hole 19 is formed, and the waterproof packing 11 is fitted to the inside of the lid body 6 in a state in which the first cylindrical protruding portion 18 protrudes upward from the first through hole 21 of the lid body 6, and the second cylindrical protruding portion 20 protrudes upward from the second through hole 22. In addition, the pair of cylindrical protruding portions of the first cylindrical protruding portion 18 and the second cylindrical protruding portion 20 can be inserted with respect to the first through hole 21 and the second through hole 22 in a replaceable manner.

[0136] ​Thus, in the lid unit 1 of the present embodiment, the waterproof packing 11 can be fitted to the inside of the lid main body 6 (between the fitting peripheral wall 15 and the peripheral wall portion 6a) in a state in which one of the pair of cylindrical protruding portions, which is the first cylindrical protruding portion 18, is inserted from the first through-hole 21 and protrudes upward, and the other of the pair of cylindrical protruding portions, which is the second cylindrical protruding portion 20, is inserted from the second through-hole 22 and protrudes upward.

[0137] Therefore, the waterproof packing 11 will not be misaligned with respect to the lid main body 6. In addition, the waterproof packing 11 can be easily fixed to an appropriate position on the inside of the lid main body 6.

[0138] In addition, in the lid unit 1 of the present embodiment, by causing the pair of cylindrical protruding portions (the first cylindrical protruding portion 18 and the second cylindrical protruding portion 20) provided at the front and rear of the waterproof packing 11 to protrude upward from the first through-hole 21 and the second through-hole 22 provided at the front and rear of the lid main body 6, it is possible to prevent the waterproof packing 11 from being twisted or displaced in position when the lid main body 6 is attached to the neck portion 2c of the container main body 2 by screwing, in sliding contact with the upper opening portion 2d (the upper end portion of the neck portion 2c).

[0139] In addition, in the lid unit 1 of the present embodiment, by fitting the plurality of positioning protrusions 23 of the waterproof packing 11 arranged in the left-right direction to the plurality of positioning recesses 24 of the lid main body 6, it is possible to further prevent the waterproof packing 11 from being twisted or displaced in position.

[0140] In addition, in the lid unit 1 of the present embodiment, by the first peg 26 provided to the lid body 9 and the second peg 30 provided to the lock member 28, it is possible to appropriately open and close the first vent hole 17 provided to the first cylindrical protruding portion 18 and the second vent hole 19 provided to the second cylindrical protruding portion 20.

[0141] As described above, in the lid unit 1 of the present embodiment, it is possible to prevent the beverage inside the container main body 2 from leaking to the outside, and to appropriately open and close the first vent hole 17 and the second vent hole 19. Therefore, in the covered container 100 of the present embodiment, by having such a lid unit 1, it is possible to achieve further improvement in convenience of use.

[0142] Furthermore, the present application is not limited to the above-described embodiments, and various modifications can be made within the scope of the present application.

[0143] For example, instead of the structure in which the plurality of (four in this case) positioning protrusions 23A shown in FIG. 10 are provided to the waterproof packing 11, a structure in which the plurality of positioning protrusions 23 provided to the waterproof packing 11 are replaced with the plurality of positioning protrusions 23A provided to the lid body 9 can also be adopted. Figure 7

[0144] ​The plurality of positioning protrusions 23A have the same shape as each other, and are provided protruding upward from positions symmetrical to each other on the upper surface of the waterproof packing 11.

[0145] On the other hand, the lid main body 6 is provided with a plurality of (four in this case) positioning recesses 24A instead of the above-described positioning recess 24, as shown in the drawing. The plurality of positioning recesses 24A have the same shape and positions as the plurality of positioning protrusions 23A, and have a shape in which the lower surface between the peripheral wall portion 6a of the upper wall portion 6b and the fitting peripheral wall 15 is recessed. Figure 8

[0146] The waterproof packing 11 is fitted to the inside of the lid main body 6 (between the peripheral wall portion 6a and the fitting peripheral wall 15) in a state in which each of the positioning protrusions 23A is fitted in each of the positioning recesses 24A. Thus, it is possible to prevent the waterproof packing 11 from being twisted or displaced in position when the lid main body 6 is attached to the neck portion 2c of the container main body 2 by screwing, and slidingly contacting the upper opening portion 2d (the upper end portion of the neck portion 2c).

[0147] Further, in the present embodiment, the structure in which the positioning protrusions 23A are provided on the waterproof packing 11 side and the positioning recesses 24A are provided on the lid main body 6 side is adopted, but a structure opposite thereto, in which the positioning recesses are provided on the waterproof packing 11 side and the positioning protrusions are provided on the lid main body 6 side, can also be adopted.

[0148] Further, in the above-described embodiment, the case in which the present application is applied to the capped container 100 in which the cold-keeping (or heat-keeping) function is maintained by the container main body 2 having a vacuum heat-insulating structure is exemplified, but is not necessarily limited to the capped container 100 provided with such a container main body 2 having a vacuum heat-insulating structure. That is, the present application can be widely applied to capped containers in which a lid unit with a straw is attached to and detached from a container main body.​
