Description

Technical Field

[0001] This invention relates to lid units and lidded containers. Background Technology

[0002] Conventionally, there exists a lidded container comprising a lid unit (stopper) that is detachably mounted to the container body with an upper opening. One proposed lid unit includes: a lid body that closes the upper opening of the container body and has a flexible straw protruding from the upper part; a lid body that is rotatably mounted to the lid body via a hinge; a lid locking mechanism that secures the lid body relative to the lid body; and a sealing member that seals the container body and the lid body (see, for example, Patent Documents 1 and 2 below).

[0003] In a beverage container equipped with such a lid unit, when the lid is fixed relative to the lid body by a lid locking mechanism, the straw is housed inside the lid body in a bent state. Furthermore, a protrusion located inside the lid body abuts against the straw, crushing it and thereby closing the straw's liquid passage. On the other hand, by releasing the lid from the locking mechanism and rotating the lid in the opening direction, the straw elastically returns from its bent state to its original position. Thus, the beverage inside the container can be drunk through the straw.

[0005] Patent Document 2: Japanese Patent No. 5662536

[0006] However, in the aforementioned cap unit with a straw, when the cap is released from its locking mechanism, in order to prevent residual liquid in the straw from scattering to the outside, an action is taken to release the air inside the container body through the vent provided at the top of the cap body (releasing the pressure inside the container to the outside).

[0007] In this case, the vent must be reliably opened before the straw elastically returns to its original state from a bent position. Furthermore, the vent must be reliably closed beforehand when the cap is secured to the cap body by the cap locking mechanism.

[0008] Furthermore, the vent is formed by the central hole of the cylindrical protrusion provided in the water-stopping sealant. The water-stopping sealant is made of annular elastic member, which is fitted into the inner side of the cover body with the cylindrical protrusion protruding upward from the through hole provided in the upper part of the cover body.

[0009] In this situation, the cylindrical protrusion needs to be pressed into the through hole from below beforehand, and the sealing sealant needs to be fixed at an appropriate position on the inside of the cap body. Furthermore, if the cylindrical protrusion is not pressed sufficiently into the through hole, it may detach from the through hole after being pressed by the protrusion used to close the vent, or insufficient pressure on the protrusion may make it difficult to properly open and close the vent. This also contributes to leakage of beverage from the container body to the outside.

[0010] Furthermore, when the sealing sealant is installed inside the cap body, it is difficult to visually observe whether the cylindrical protrusion is reliably pressed into the through hole. If the cylindrical protrusion is not sufficiently pressed into the through hole, there is a possibility that the sealing sealant may deviate from its proper position when the cap body is screwed onto the neck of the container body. Summary of the Invention

[0011] The present invention was made in view of the existing situation, and aims to provide a lid unit with a straw that can prevent the beverage inside the container body from leaking out and properly open and close the vent, and a lidded container that can further improve the ease of use by having such a lid unit.

[0012] To achieve the above objectives, the present invention provides the following solutions.

[0013] [1] A cover unit, which is detachably mounted to a container body with an upper opening, characterized in that it comprises:

[0014] The cover body is installed with the upper opening of the container body closed.

[0015] A straw component, comprising a straw portion protruding from the upper part of the aforementioned cap body;

[0016] The lid is rotatably mounted to the lid body via the first hinge, and the straw is housed inside in a bent state.

[0017] A cover locking mechanism, located on the side of the cover body opposite to the first hinge portion, secures the cover body relative to the cover body when the upper part of the cover body is closed; and

[0018] The valve component is detachably mounted on the upper part between the suction tube portion and the cap locking mechanism of the cap body.

[0019] The aforementioned cover body has a fitting portion for inserting the aforementioned valve component, and a first through hole and a second through hole penetrating the bottom of the fitting portion.

[0020] The valve component described above has a first vent and a second vent.

[0021] With the first through hole connected to the first vent hole and the second through hole connected to the second vent hole, the valve component is fitted into the fitting portion.

[0022] [2] The cover unit described in [1] above is characterized in that,

[0023] The valve component described above has a cylindrical protrusion provided with the first vent or the second vent.

[0024] The aforementioned cylindrical protrusion is fitted into either the first through hole or the second through hole.

[0025] [3] The cover unit described in [1] or [2] above is characterized in that,

[0026] The aforementioned cover locking mechanism includes: a locking member, which is rotatably mounted to the front side of the cover body via a second hinge; a force-applying member, which applies force to the locking member toward the rotation direction; and a plug portion disposed on the locking member.

[0027] The aforementioned locking member can rotate freely between a locked position where the first locking portion on the locking member side is locked to the first locked portion on the cover side, and a locked-out position where the locking state of the first locking portion and the first locked portion is released.

[0028] When the locking member, which has been subjected to force by the aforementioned force-applying component, is in the locked position, the plug portion is in close contact with the periphery of the first vent, thereby closing the first vent.

[0029] When the locking member is in the unlocked position in a manner that overcomes the force applied by the force-applying member, the plug separates from the periphery of the first vent, thereby opening the first vent.

[0030] [4] The cover unit described in [3] above is characterized in that,

[0031] The locking member described above has an upper arm extending upward from the second hinge portion, a lower arm extending downward from the second hinge portion, and a rear arm extending rearward from the upper arm portion.

[0032] The first locking part is provided on the front end side of the upper arm.

[0033] The aforementioned plug is located on the front end side of the aforementioned rear arm.

[0034] [5] The cover unit described in [3] or [4] above is characterized in that,

[0035] The aforementioned cover locking mechanism has a second locking portion disposed on the side of the locking component and a second locked portion disposed on the side of the cover body.

[0036] From the state where the cover is fixed relative to the cover body, the locking member is rotated from the locked position to the unlocked position. This causes the second locking portion to engage with the second locked portion when the first vent is open, thus restricting the cover from rotating to that side.

[0037] From this state, the locking member is rotated from the unlocked position to the locked position, thereby releasing the locking state between the second locking part and the second locked part, and the cover rotates toward the aforementioned side.

[0038] [6] The cover unit according to any one of [1] to [5] above is characterized in that,

[0039] The aforementioned cover has a protrusion extending from its inner lower surface.

[0040] With the cap body fixed relative to the cap body by the cap locking mechanism, the protrusion that abuts against the straw part crushes the straw part and closes the liquid passage of the straw part. The straw part crushed by the protrusion is in close contact with the area around the second vent, thus closing the second vent.

[0041] [7] The cover unit according to any one of [1] to [6] above is characterized in that,

[0042] The aforementioned cover body has a peripheral wall portion, an upper wall portion covering the upper surface of the peripheral wall portion, a mounting hole penetrating the upper wall portion, and a fitting protrusion protruding from the lower surface of the upper wall portion.

[0043] The straw component described above has a sealing portion that protrudes from the middle portion in the length direction of the straw portion in the expansion direction, and a fitting hole provided in the sealing portion.

[0044] With the straw portion passing through the mounting hole and the fitting protrusion engaged in the fitting hole, the sealing portion is fitted into the inner side of the cap body, thereby allowing the straw component to be easily attached and detached from the cap body.

[0045] With the lid body installed on the container body, the sealing part seals the container body and the lid body together.

[0046] [8] A lidded container, characterized in that it comprises:

[0047] The cover unit described in any of [1] to [7] above; and

[0048] The container body is equipped with the aforementioned cover unit.

[0049] [9] The covered container according to [8] above is characterized in that,

[0050] The container body described above has a vacuum insulation structure.

[0051] As described above, according to the present invention, it is possible to provide a lid unit with a straw that can prevent beverage inside the container body from leaking out and to properly open and close the vent, and a lidded container that can further improve ease of use by having such a lid unit.

Figure 12 This is a perspective view showing the structure of the water-stopping and sealing component 34, which is separately set with the cover unit 1.

[0069] 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 installed in a detachable manner, and can drink beverages (liquids) inside the container body 2 through the straw part 7a described later.

[0070] Furthermore, in the lidded container 100 of this embodiment, the beverage (contents) contained in the container body 2, which has a vacuum insulation structure, can be kept cold (or warm).

[0071] Specifically, the container body 2 is composed of a double-layered container having a bottomed cylindrical outer container 3 made of, for example, stainless steel, and an inner container 4, which are joined together by connecting their opening edges so that the inner container 4 is housed inside the outer container 3. Furthermore, a vacuum insulation layer 5 is provided between the outer container 3 and the inner container 4. The vacuum insulation layer 5 can be formed, for example, by blocking an exhaust vent located at the center of the bottom surface of the outer container 3 within a chamber that has been depressurized (evacuated) to a high vacuum.

[0072] The container body 2 has a generally circular bottom 2a, a generally cylindrical cylindrical body portion 2b that rises from the outer periphery of the bottom 2a, and a generally cylindrical neck portion 2c that is narrowed at the upper side of the cylindrical body portion 2b. Furthermore, the upper end of the neck portion 2c has a circular opening as the upper opening portion 2d of the container body 2.

[0073] Furthermore, in the lidded container 100 of this embodiment, the container body 2 has a generally cylindrical external shape as a whole, but there is no particular limitation on the external shape of the container body 2, and appropriate changes can be made to match the size, appearance design, etc. In addition, painting, printing, etc. can also be performed on the outer peripheral surface of the container body 2.

[0074] like Figures 2-7As shown, the lid unit 1 of this embodiment includes: a lid body 6 that closes the upper opening 2d of the container body 2; a straw component 7 that includes a straw portion 7a protruding from the upper part of the lid body 6; a lid 9 that is rotatably mounted to the lid body 6 via a first hinge portion 8; a lid locking mechanism 10 that fixes the lid 9 relative to the lid body 6; and a valve component 11 that is mounted on the upper part between the straw portion 7a of the lid body 6 and the lid locking mechanism 10.

[0075] In addition, in the lidded container 100 of this embodiment, the side of the lid unit 1 where the first hinge portion 8 is provided is designated as the "rear side", and the side opposite to the side where the first hinge portion 8 is provided is designated as the "front side".

[0076] The cover body 6 is made of, for example, a synthetic resin such as polypropylene. The cover body 6 has a peripheral wall portion 6a formed in a generally cylindrical shape and an upper wall portion 6b covering the upper surface of the peripheral wall portion 6a.

[0077] The cap body 6 is screwed onto the neck portion 2c of the container body 2 for easy attachment and detachment. Therefore, an internal thread portion 12 is provided on the inner circumferential surface of the peripheral wall portion 6a. On the other hand, an external thread portion 13 that engages with the internal thread portion 12 is provided on the outer circumferential surface of the neck portion 2c of the container body 2.

[0078] The cover body 6 has a mounting hole 14 that passes through the general center of the upper wall portion 6b, and a fitting protrusion 15 that is located in front of the mounting hole 14 and protrudes from the lower surface of the upper wall portion 6b.

[0079] The straw component 7 is made of rubber such as silicone rubber, elastic components such as elastomers, and has: a straw portion 7a formed into a tube shape, a sealing portion 7b protruding from the middle of the straw portion 7a in the length direction in the expansion direction, a fitting hole 7c provided in the sealing portion 7b, and a tube connecting portion 7d provided at the lower end of the straw portion 7a.

[0080] The straw component 7 is installed on the inner side of the cap body 6 by having the straw portion 7a pass through the mounting hole 14 and the fitting hole 7c fitting with the fitting protrusion 15, thereby allowing the sealing portion 7b to be fitted into the inner side of the cap body 6 in a way that allows it to be easily installed and removed.

[0081] Furthermore, the straw component 7 can be removed from the lid body 6 and washed separately from the lid body 6, thereby maintaining hygiene between the straw component 7 and the lid body 6.

[0082] The straw portion 7a bends forward while protruding from the upper part of the cap body 6.

[0083] When the cap body 6 is installed on the neck 2c of the container body 2, the sealing part 7b is in a state of being tightly attached to the upper opening 2d (the upper end of the neck 2c) all around the circumference, thereby functioning as a water-stopping sealant to seal the container body 2 and the cap body 6.

[0084] A suction tube 16 for inhaling the beverage contained in the container body 2 is connected to the tube connection 7d. The suction tube 16 is cylindrical and extends from the tube connection 7d to near the bottom of the container body 2. Therefore, even if the amount of beverage in the container body 2 decreases, it is possible to drink until the last drop is consumed.

[0085] Furthermore, the lower end of the inhalation tube 16 can be appropriately modified to a shape in which a portion of it is cut at an angle, or to a shape cut in a wavy shape, etc. Therefore, even if the lower end of the inhalation tube 16 comes into contact with the inner bottom surface or inner side surface of the container body 2, it is possible to prevent the inhalation tube 16 from sticking to or making it difficult to drink the beverage inside the container body 2.

[0086] The cover 9 is made of, for example, a synthetic resin such as polypropylene. The cover 9 has a peripheral wall portion 9a formed in a generally cylindrical shape and a top wall portion 9b covering the top surface of the peripheral wall portion 9a. The cover 9 is rotatably mounted to the cover body 6 via a first hinge portion 8 provided on the upper part of the rear end side of the cover body 6.

[0087] Furthermore, a protrusion 17 is provided on the lower inner surface of the cover 9. The straw portion 7a is housed inside the cover 9 in a bent state by passing through the protrusion 17.

[0088] The cover locking mechanism 10 includes: a locking member 19 that is rotatably mounted on the front side of the cover body 6 via a second hinge portion 18; a force-applying member 20 that applies force to the side of the locking member 19 toward the rotation direction; and a plug portion 21 provided on the locking member 19.

[0089] The locking member 19 has an upper arm 19a extending upward from the second hinge portion 18, a lower arm 19b extending downward from the second hinge portion 18, and a rear arm 19c extending rearward from the upper arm 19a.

[0090] The force-applying component 20 is, for example, composed of an elastic component such as a coil spring. The force-applying component 20 is disposed in a compressed state between the lower arm portion 19b and the peripheral wall portion 6a. Alternatively, elastic components such as silicone rubber or elastomers can also be used for the force-applying component 20.

[0091] The plug 21 protrudes downward from the front end of the rear arm 19c.

[0092] The cover locking mechanism 10 has a first locking portion 22 provided on the side of the locking member 19 and a first locked portion 23 provided on the side of the cover body 9. The first locking portion 22 is composed of a hook portion that protrudes rearward from the front end of the upper arm portion 19a. The first locked portion 23 is composed of a hook portion that protrudes forward from the lower end of the front side of the cover body 9.

[0093] In the cover locking mechanism 10, such as Figure 2 As shown, when the cover 9 closes the upper part of the cover body 6, the first locking part 22 on the locking member 19 side, which is subjected to force by the force-applying member 20, locks with the first locked part 23 on the cover 9 side, thereby fixing the cover 9 relative to the cover body 6.

[0094] The locking member 19 can rotate freely between the locked position where the first locking part 22 and the first locked part 23 are locked, and the locked release position where the locking state of the first locking part 22 and the first locked part 23 is released.

[0095] Therefore, in the cover locking mechanism 10, as Figure 3 As shown, a pressing operation is performed on the lower arm 19b side of the locking member 19 in a manner that overcomes the force applied by the force-applying member 20, thereby enabling the locking member 19 to rotate from the locked position to the unlocked position while releasing the locking state of the first locking part 22 and the first locked part 23.

[0096] Furthermore, the cover locking mechanism 10 has a second locking portion 24 provided on the side of the locking member 19 and a second locked portion 25 provided on the side of the cover body 9. The second locking portion 24 is composed of a hook portion protruding upward from the front end of the rear arm portion 19c. The second locked portion 25 is composed of a hook portion protruding rearward from the lower end of the front side of the cover body 9.

[0097] In the cover locking mechanism 10, such as Figure 2 As shown, from the state where the cover 9 is fixed relative to the cover body 6, as Figure 3 As shown, a pressing operation is performed on the lower arm portion 19b of the locking member 19, causing the locking member 19 to rotate from the locked position to the unlocked position. This releases the locking state between the first locking portion 22 and the first locked portion 23. Subsequently, the second locking portion 24 on the locking member 19 side locks with the second locked portion 25 on the cover 9 side. This restricts the rotation of the cover 9 to one side (opening direction).

[0098] On the other hand, in the cover locking mechanism 10, from the Figure 3 From the locked state shown, as Figure 4As shown, by releasing the pressing operation relative to the aforementioned locking member 19, the locking member 19, which has been subjected to force by the force-applying member 20, rotates from the unlocked position to the locked position, thereby releasing the locking state of the second locking part 24 and the second locked part 25. As a result, the cover 9 can rotate freely (open and close).

[0099] On the other hand, in the cover locking mechanism 10, from Figure 4 From the indicated state, the cover 9 is rotated towards the upper part of the closing cover body 6 (closing direction). This causes the first locking part 22 and the first locked part 23 to slide into contact, and simultaneously, overcoming the force applied by the force-applying member 20, the locking member 19 rotates from the locked position to the unlocked position. Furthermore, the first locking part 22 passes over the first locked part 23, thereby causing the locking member 19 to rotate from the unlocked position to the locked position by the force applied by the force-applying member 20. At this time, the first locking part 22 and the first locked part 23 are locked together. Thus, as shown... Figure 2 As shown, the cover 9 closes the upper part of the cover body 6, thus fixing the cover 9 relative to the cover body 6.

[0100] like Figures 2-7 As shown, the valve component 11 is made of rubber such as silicone rubber, elastic components such as elastomers, and is formed as a generally rectangular flat plate. The valve component 11 has a cylindrical protrusion 27 with a first vent 26 on the front side and a second vent 28 on the rear side.

[0101] The cover body 6 has a fitting portion 29 into which the valve component 11 is inserted, a first through hole 30 through the front side of the bottom of the fitting portion 29, and a second through hole 31 through the rear side of the bottom of the fitting portion 29.

[0102] The valve component 11 is fitted inside the fitting portion 29 with the cylindrical protrusion 27 fitted into the first through hole 30, thereby being installed on the cover body 6 in a way that allows for easy installation and removal. As a result, the second vent hole 28 is connected to the second through hole 31.

[0103] Furthermore, by removing the valve component 11 from the cover body 6, it can be cleaned separately from the cover body 6, thereby maintaining hygiene between the valve component 11 and the cover body 6.

[0104] In addition, the fitting portion 29 in this embodiment is formed by a recess provided on the upper part of the cover body 6, but it is not necessarily limited to such a structure. For example, it can also be a structure that allows the rib that can be fitted into the valve component 11 to protrude from the upper surface of the cover body 6.

[0105] In the cover unit 1 of this embodiment, which has the structure described above, as follows: Figure 2As shown, when the cap 9 closes the upper part of the cap body 6, the straw portion 7a is housed inside the cap 9 in a bent state at two points. Furthermore, the protrusion 17 that abuts against the straw portion 7a crushes the straw portion 7a while closing the liquid passage of the straw portion 7a.

[0106] At this time, the plug portion 21 of the locking member 19 is in close contact with the periphery of the first vent 26 of the valve member 11, thereby closing the first vent 26. In addition, the straw portion 7a, which is crushed by the protrusion 17 of the cover body 9, is in close contact with the periphery of the second vent 28, thereby closing the second vent 28.

[0107] Therefore, with the lid 9 closing the upper part of the lid body 6, it is possible to prevent the beverage inside the container body 2 from leaking out.

[0108] In the cover unit 1 of this embodiment, from the Figure 2 From the closed state shown, as Figure 3 As shown, a pressing operation is performed on the lower arm portion 19b side of the locking member 19, thereby rotating the locking member 19 from the locked position to the unlocked position and releasing the locking state of the first locking portion 22 and the first locked portion 23.

[0109] At this time, the second locking part 24 is locked to the second locked part 25. In addition, the plug part 21 of the locking member 19 separates from the periphery of the first vent hole 26, thereby opening the first vent hole 26.

[0110] Furthermore, the first vent 26 rotates from the locked position to the unlocked position via the locking member 19, thus opening before the cover 9 rotates in the opening direction. At this time, the first vent 26 opens before the locking state of the first locking part 22 and the first locked part 23 is released.

[0111] This allows the air inside the container body 2 to be released to the outside through the first vent 26 (releasing the pressure inside the container body 2 to the outside), and then the straw section 7a elastically recovers, thereby opening the liquid passage of the straw section 7a, thus preventing the residual liquid inside the straw section 7a from scattering to the outside.

[0112] In the cover unit 1 of this embodiment, from the Figure 3 From the locked state shown, as Figure 4 As shown, when the pressing operation on the locking member 19 is released, the locking member 19, which was subjected to force by the force-applying member 20, rotates from the locked-out position to the locked position, thereby releasing the locking state of the second locking part 24 and the second locked part 25.

[0113] At this time, the straw portion 7a pushes up the cover 9 while elastically returning to its original state from a bent state. Furthermore, as the straw portion 7a elastically returns to its original state, the cover 9 rotates in the opening direction. Additionally, the straw portion 7a separates from the area around the second vent 28, thus opening the second vent 28.

[0114] On the other hand, by tightly fitting the plug 21 of the locking member 19 around the first vent 26, the first vent 26 is closed again. This prevents the beverage inside the container body 2 from leaking out, and allows the user to drink the beverage inside the container body 2 while sucking through the straw 7a.

[0115] Furthermore, as the beverage inside the container body 2 decreases, the pressure inside the container body 2 becomes negative. At this time, outside air is introduced into the interior of the container body 2 through the second vent 28. As a result, the pressure inside the container body 2 returns to atmospheric pressure, so the beverage inside the container body 2 can be continued to be consumed through the straw part 7a.

[0116] As described above, in the cover unit 1 of this embodiment, the valve component 11, which is provided with the first vent hole 26 and the second vent hole 28, is fitted into the fitting part 29 provided on the upper part of the cover body 6, thereby enabling the valve component 11 to be installed at an appropriate position on the cover body 6.

[0117] Furthermore, in the cover unit 1 of this embodiment, since the valve component 11, which is separate from the straw component 7, is installed on the outside of the cover body 6, the first vent hole 26 and the second vent hole 28 provided on the valve component 11 will not be misaligned.

[0118] Furthermore, in the cover unit 1 of this embodiment, the first vent hole 26 provided in the valve member 11 can be opened and closed appropriately by means of the plug portion 21 provided in the locking member 19. In addition, the alignment of the second through hole 31 provided in the cover body 6 and the second vent hole 28 provided in the valve member 11 is also easier.

[0119] Furthermore, in the cover unit 1 of this embodiment, a pressing operation is performed on the lower arm portion 19b side of the locking member 19 to overcome the force applied by the force-applying member 20. While the locking member 19 is rotated from the locked position to the unlocked position, the valve member 11 is attached to and detached from the cover body 6, thus preventing the valve member 11 from being mistakenly removed. Furthermore, the plug portion 21 of the locking member 19, which is subjected to force by the force-applying member 20, abuts against the valve member 11, thereby preventing the valve member 11 from falling off the cover body 6.

[0120] Furthermore, in the cap unit 1 of this embodiment, with the fitting protrusion 15 of the cap body 6 fitted into the fitting hole 7c of the straw component 7, a sealing portion 7b is fitted inside the cap body 6. Therefore, when the cap body 6 is screwed onto the neck portion 2c of the container body 2, twisting or positional deviation of the sealing portion 7b, which slides into contact with the upper opening 2d (the upper end of the neck portion 2c), can be prevented.

[0121] Furthermore, in the cover unit 1 of this embodiment, by using the straw component 7, which integrates the straw portion 7a and the sealing portion 7b, the structure can be simplified, thereby making it easier to assemble and disassemble the cover body 6.

[0122] As described above, in the lid unit 1 of this embodiment, the beverage inside the container body 2 can be prevented from leaking out, and the opening and closing of the first vent 26 and the second vent 28, which release air from inside the container body 2, can be appropriately performed. Therefore, in the lidded container 100 of this embodiment, by providing such a lid unit 1, the ease of use can be further improved.

[0123] Furthermore, the present invention is not necessarily limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0124] For example, in the cover unit 1 described above, the structure is not necessarily limited to that of the valve component 11 described above; for example, it can also be... Figure 8 The structure is as shown in the valve component 11A. The valve component 11A has a first vent 26 on the front side and a cylindrical protrusion 27 with a second vent 28 on the rear side.

[0125] In this configuration, when the cylindrical protrusion 27 of the valve component 11A is fitted into the second through hole 31 of the cover body 6, and the first vent hole 26 of the valve component 11A is connected to the first through hole 30 of the cover body 6, the valve component 11A is fitted into the fitting portion 29 of the cover body 6.

[0126] Furthermore, in the aforementioned cover unit 1, for example, Figure 9 As shown, it can also be configured such that a notch or recess 32 is provided around the fitting portion 29, making it easy to remove the valve component 11 from the fitting portion 29.

[0127] Furthermore, in the aforementioned cover unit 1, for example, Figure 10 As shown, the valve component 11 can also be configured such that a lifting piece 33 is provided on the valve component 11, and the valve component 11 can be easily removed from the fitting part 29 by pulling the lifting piece 33.

[0128] Additionally, when such a lifting plate 33 is set, such as Figure 11As shown, the straw portion 7a, which is crushed by the protrusion 17 of the cover 9, bends the lifting plate 33 while adhering tightly to the periphery of the second vent 28, thereby closing the second vent 28.

[0129] Furthermore, in the aforementioned cover unit 1, for example, Figure 12 As shown, it is also possible to configure the sealing part 7b of the straw component 7 as a water-stopping sealant 34 separately from the straw component 7.

[0130] Furthermore, the above embodiments illustrate the application of the present invention to a lidded container 100 that has a cold-keeping (or heat-keeping) function due to a container body 2 having a vacuum-insulated structure, but it is not necessarily limited to a container body 2 having such a vacuum-insulated structure. That is, the present invention can be widely applied to lidded containers with straws that are detachably mounted on the container body.
