Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the case of the one-way opening bottle as described above, when the locking claw of the locking member is locked to the engaging portion of the one-way opening lid and the one-way opening lid is closed and the unlocking member is in the initial position before the preliminary operation, the facing position between the stopper of the plug body and the unlocking member is located on the side opposite to the side where the locking claw of the locking member is disposed with respect to the fulcrum of the locking member in a front view. And when the locking member, the one-way opening lid, etc. are formed of a material with relatively low strength such as resin, if a large load in the direction of opening the one-way opening lid is applied to the one-way opening lid, the one-way opening lid side cannot resist the load, and a large load is also applied to the locking claw of the locking member and the engaging portion of the one-way opening lid, and there is a risk that the locking claw of the locking member and the engaging portion of the one-way opening lid will be deformed or damaged.

[0005] An object of the present invention is to provide a plug body that can reduce the risk of deformation and breakage of the locked portion of the lid body and the locking portion of the locking mechanism as much as possible even when a large load in the direction of opening the lid body is applied to the lid body.

Means for Solving the Problems

[0006] The plug body according to the present invention is a plug body having a discharge port formed therein, a lid body having a locked portion and covering the discharge port in an openable and closable manner, a locking mechanism having a locking portion capable of locking the locked portion, a rotation axis, and a locking state in which the locked portion is locked to the locking portion and the lid body is in a closed state, and an unlocking state in which the rotation axis is rotated around the rotation axis by being operated and the locking state is released and the lid body can be opened, and the locking mechanism is attached to the plug body, a locking member attached to the plug body, which can be operated to switch between a releasable state in which the locking mechanism can be changed from the locked state to the unlocked state and a non-releasable state in which the locking mechanism is blocked from changing from the locked state to the unlocked state at a first position, The first position is located on the side where the locking portion is disposed with respect to the rotation axis in a front view of the locked state, and is a position where the lid body and the locking member face each other.

[0007] According to the above configuration, the lock member can prevent the locking mechanism from changing from the locked state to the released state at the first position. The first position is located on the side where the locking portion is disposed with respect to the rotation axis in a front view of the locked state, and is a position where the lid body and the lock member face each other. Therefore, in this plug body, even if a large load in the direction of opening the lid body is applied to the lid body, it can resist on the lid body side rather than on the plug body side against the load, and the locked portion of the lid body and the locking portion of the locking mechanism can be reduced as much as possible the risk of deformation and breakage.

[0008] In the present invention, it is preferable that the operation on the locking mechanism is performed via the lock member.

[0009] According to the above configuration, the user can operate the lock member with a finger so that the lock member changes from the non-releasable state to the releasable state, and then further operate the lock member with a finger as it is to release the locking mechanism and open the lid body. Therefore, with this plug body, the opening operation of the lid body can be performed smoothly.

[0010] In the present invention, it is preferable that the lock member is switched to the releasable state by being operated along the direction from the locking portion toward the rotation axis in a front view of the locked state, and is switched to the non-releasable state by being operated along the direction from the rotation axis toward the locking portion in a front view of the locked state.

[0011] According to the above configuration, compared with the case where the lock member is operated along the direction from the rotation axis toward the locking portion in a front view of the locked state and switched to the releasable state, or the case where the lock member is operated along the direction from the locking portion toward the rotation axis in a front view of the locked state and switched to the non-releasable state, the operation direction of the lock member can be intuitively recognized by the user.

[0012] In the present invention, The locking member prevents the locking mechanism from changing from the locked state to the released state at the first position and the second position. The second position is preferably located on the side opposite to the side where the locking portion is disposed with respect to the rotation axis in a front view of the locked state.

[0013] According to the above configuration, the locking member can prevent the locking mechanism from changing from the locked state to the released state at two positions, namely the first position and the second position. Therefore, with this plug body, even if a large load in the direction of opening the lid is applied to the lid, the risk of deformation or breakage of the locked portion of the lid and the locking portion of the locking mechanism can be further reduced.

[0014] In the present invention, the lid further has a first opposing portion that opposes the locking member at the first position. the plug body has a second opposing portion that opposes the locking member at the second position. It is preferable that the direction of the surface on the side of the first opposing portion that faces the locking member and the direction of the surface on the side of the second opposing portion that faces the locking member are opposite to each other.

[0015] According to the above configuration, when the locking member is in a non-lockable state, it is possible to prevent the unlocking impossible state from being unexpectedly released due to a load for rotating the locking member being unexpectedly applied to the locking member and the locking member rotating, by means of the first opposing portion and the second opposing portion disposed at the rotation end of the locking member.

[0016] In the present invention, the locking member has an operating portion that is operated during an operation on the locking member, and an interlocking portion that interlocks with the operating portion. The first opposing portion faces the interlocking portion at the first position. The second opposing portion preferably faces the operating portion at the second position.

[0017] According to the above configuration, when the locking member is in a non-lockable state, it is possible to prevent the unlocking impossible state from being unexpectedly released by the rotation of the locking member due to an unexpected load applied to the locking member by arranging a first opposing portion and a second opposing portion disposed at the rotation destination of the locking member.

[0018] In the present invention, It is preferable that the interlocking portion has a color different from that of the operation portion, is not exposed in the unlocking impossible state, and is exposed in the unlocking possible state.

[0019] According to the above configuration, it is possible to clearly make the user recognize whether the locking member is in an unlockable state or an unlocking impossible state, and it is possible to prevent the locking member from remaining in the unlockable state after the lid body is closed as much as possible.

[0020] In the present invention, The locking mechanism further has a lever portion through which the rotation shaft is inserted. The interlocking portion has a position holding portion for holding the unlockable state and the unlocking impossible state, is slidably fitted to the lever portion, and preferably rotates together about the rotation shaft when the locking mechanism rotates about the rotation shaft by an operation on the locking mechanism.

[0021] According to the above configuration, it is possible to prevent the locking member from being unexpectedly switched to the unlockable state or the unlocking impossible state as much as possible.

[0022] The beverage container according to the present invention A plug body according to any one of claims 1 to 8, And a container to which the plug body is attached.

[0023] According to the above configuration, the above-described plug body is attached to this beverage container. Therefore, this beverage container can exhibit the above-described effects.

Then, as shown in FIGS. 1 to 5, 9, and 11, a convex finger receiving portion 151a extending forward is formed at the upper part of the front portion of the main body portion 151A. This finger receiving portion 151a functions as a portion where the user places a finger when operating the slide lock component 151. When the slide lock component 151 is in the upper position (i.e., when the lock member LM is in the locked state), the lower end portion 151b of the main body portion 151A is in proximity to and opposed to the lower protrusion 111D of the base portion 111 of the plug body 110 (see FIG. 5). On the other hand, when the slide lock component 151 is in the lower position (i.e., when the lock member LM is in the unlocked state), the lower end portion 151b of the main body portion 151A does not oppose the lower protrusion 111D of the base portion 111 of the plug body 110 (see FIG. 13). Further, as shown in FIGS. 5, 10, and 11, a recess 151c is formed on the rear side of the finger receiving portion 151a in the main body portion 151A. By fitting the fitting protrusion 152D of the intermediate connecting component 152 into this recess 151c, the slide lock component 151 and the intermediate connecting component 152 are connected so as to be interlockable. When the fitting protrusion 152D of the intermediate connecting component 152 is fitted into the recess 151c, the left and right end portions of the base portion 152A of the intermediate connecting component 152 are respectively located above the pair of wing portions 151B (see FIGS. 8 and 11). The wing portions 151B extend rearward from the lower portions and the central portion of the left and right ends of the main body portion 151A as shown in FIGS. 8 to 11. Further, as shown in FIGS. 8 to 11, a long hole HL1 is formed in this wing portion 151B. A shaft SH is inserted through this long hole HL1. Since this shaft SH is fixed, the slide lock component 151 can slide in the vertical direction along this long hole HL1. Further, as shown in FIGS. 8, 10, and 11, retaining portions 151d are respectively formed at the lower portions on the opposing surface side of the pair of wing portions 151B.When a part of the intermediate connecting component 152 and a part of the opening / closing lever component 153 are accommodated between the pair of wing portions 151B, the retaining portion 151d serves to restrict the movement of the intermediate connecting component 152 and the opening / closing lever component 153 in the front-rear direction.

[0047] (2-5-2) Intermediate Connecting Component The intermediate connecting component 152 is a component with a color different from that of the slide lock component 151, and serves to connect the slide lock component 151 and the opening / closing lever component 153 so that the slide lock component 151 can slide relative to the opening / closing lever component 153, to maintain the slide lock component 151 in the upper position when the lock member LM is locked, and to maintain the slide lock component 151 in the lower position when the lock member LM is unlocked. As shown in FIGS. 5, 8 to 12, the intermediate connecting component 152 is mainly formed of a base body portion 152A, a plate portion 152B, a position holding projection portion 152C, a fitting projection portion 152D, a pair of outer slide portions 152E, and a pair of inner slide portions 152F. The base body portion 152A is a plate member having a substantially reverse concave shape in a front view (see FIGS. 8 to 11). When the slide lock component 151 is in the upper position, the upper end portion of the base body portion 152A is close to and opposed to the front wall portion 125B of the cover portion 125 (see FIG. 5). On the other hand, when the slide lock component 151 is in the lower position, the upper end portion of the base body portion 152A is located below the front wall portion 125B of the cover portion 125 and is in a state of not facing the front wall portion 125B of the cover portion 125 and is exposed (see FIGS. 4 and 13). The plate portion 152B extends downward from the lower portion of the central portion in the width direction of the base body portion 152A as shown in FIGS. 8 to 11. The position holding projection portion 152C is a convex portion extending forward from the lower portion of the front portion of the plate portion 152B as shown in FIGS. 5, 9 to 11. When the slide lock component 151 is in the upper position, the position holding projection portion 152C is located above the position holding projection portion 153G of the opening / closing lever component 153 and abuts against the position holding projection portion 153G of the opening / closing lever component 153, and the slide lock component 151 is maintained in the upper position. Further, when the slide lock component 151 is in the lower position, the position holding projection portion 152C is located below the position holding projection portion 153G of the opening / closing lever component 153 and abuts against the position holding projection portion 153G of the opening / closing lever component 153, and the slide lock component 151 is maintained in the lower position. The fitting projection portion 152D extends forward from the left and right portions of the base body portion 152A as shown in FIGS. 9 and 10.As described above, the fitting projection portion 152D is a portion for being fitted into the concave portion 151c of the slide lock component 151 to connect the slide lock component 151 and the intermediate connection component 152 in an interlockable manner. As shown in FIGS. 9 and 10, the outer slide portion 152E extends downward from the left and right portions of the base body portion 152A, respectively. As shown in FIGS. 9 and 10, the inner slide portion 152F is formed on the opposed surface side of a pair of the outer slide portions 152E of the intermediate connection component 152. The inner slide portion 152F is accommodated in the accommodation space 153a of the opening / closing lever component 153, and the intermediate connection component 152 is fitted with the opening / closing lever component 153 so as to be slidable in the vertical direction (see FIG. 12). Note that the slide movement of the intermediate connection component 152 is performed together when the slide lock component 151 connected to the intermediate connection component 152 slides in the vertical direction along the long hole HL1.

[0048] (2-5-3) Opening / Closing Lever Component As shown in FIGS. 5, 8 to 12, the opening / closing lever part 153 is mainly formed by a claw part 153A, a rear wall part 153B, side wall parts 153C, a front wall part 153D, a bottom wall part 153E, a spring fitting part 153F, a position holding projection part 153G, and a bearing part 153H. The claw part 153A is formed at the upper end side of the rear part of the rear wall part 153B of the opening / closing lever part 153 as shown in FIGS. 5, 8 to 11. As described above, when the lid body 120 is in the closed state, the claw part 153A and the claw part 122 of the lid body 120 are in a locked state. The rear wall part 153B extends downward from the left and right parts of the claw part 153A as shown in FIGS. 9 to 11. The side wall parts 153C extend forward from the opposite sides of the pair of rear wall parts 153B as shown in FIGS. 9 to 12. The front wall part 153D is a substantially rectangular plate member formed on the front side of the side wall parts 153C as shown in FIGS. 9 and 12. The bottom wall part 153E extends from the lower ends of the pair of rear wall parts 153B to the lower end of the front wall part 153D as shown in FIGS. 9 and 12. As shown in FIGS. 9 and 12, an accommodation space 153a is formed by the rear wall part 153B, the side wall parts 153C, the front wall part 153D, and the bottom wall part 153E. As described above, the inner slide part 152F of the intermediate connection part 152 is accommodated in this accommodation space 153a. The spring fitting part 153F is a convex part extending rearward from the lower part of the rear part of the front wall part 153D as shown in FIGS. 5, 8, 10, and 11. As shown in FIG. 5, one end of a forward biasing coil spring Sf is attached to this spring fitting part 153F. The position holding projection part 153G is a convex part extending rearward from the upper part of the rear part of the front wall part 153D as shown in FIG. 11. As described above, this position holding projection part 153G is in contact with the position holding projection part 152C of the intermediate connection part 152. The bearing parts 153H are respectively formed at the rear parts of the pair of rear wall parts 153B as shown in FIGS. 8 to 12. As shown in FIGS. 8 to 12, a bearing hole HL2 is formed in the bearing part 153H, and a shaft SH is inserted into this bearing hole HL2.

[0049] (2-5-4) Shaft As described above, the shaft SH is inserted through the long hole HL1 of the wing portion 151B of the slide lock component 151 and the bearing hole HL2 of the opening / closing lever component 153. Therefore, the slide lock component 151, the intermediate connection component 152, and the opening / closing lever component 153 can rotate about this shaft SH in the unlocked state. Further, the slide lock component 151 and the intermediate connection component 152 can slide in the vertical direction along the long hole HL1 with respect to the shaft SH.

[0050] (2-5-5) Front biasing coil spring One end of the front biasing coil spring Sf is attached to the spring fitting portion 153F of the opening / closing lever component 153 as described above. Also, the other end of the front biasing coil spring Sf is attached between the lower protrusion 111D and the upper protrusion 111E of the outer wall portion 111C of the base portion 111 of the plug body 110 as shown in FIG. 5. And this front biasing coil spring Sf biases the portion of the opening / closing lever component 153 located below the bearing portion 153H forward. Since the opening / closing lever component 153 is pivotally supported by the shaft SH as described above, the portion of the opening / closing lever component 153 located above the bearing portion 153H (that is, the claw portion 153A) is indirectly biased rearward.

[0051] <Regarding the usage method and operation mode of the beverage container according to the embodiment of the present invention> Hereinafter, the usage method and operation and the like of the beverage container 1 according to the embodiment of the present invention will be described. First, the user of this beverage container 1 pours a desired beverage into the vacuum double container 10. Next, the user closes the lid body 120 of the plug body 100 and sets the plug body 100 in the locked state (see FIG. 5). Then, the user attaches the plug body 100 to the vacuum double container 10 by screwing the male screw portion 113a of the lower cylindrical wall portion 113 of the plug body 100 into the female screw portion of the inner cylinder of the vacuum double container 10 to complete the beverage container 1. At this time, the packing PK1 abuts against the upper end of the vacuum double container 10 to keep the vacuum double container 10 and the plug body 100 watertight.

[0052] As shown in FIG. 5, when the lock member LM of the plug body 100 is in the locked state, the claw portion 122 of the lid body 120 is locked to the claw portion 153A of the opening / closing lever component 153. At this time, the portion of the opening / closing lever component 153 located below the bearing portion 153H is biased forward by the forward biasing coil spring Sf. Therefore, the claw portion 153A of the opening / closing lever component 153 located above the bearing portion 153H is biased rearward. Also, when the lock member LM of the plug body 100 is in the locked state, the slide lock component 151 is in the upper position, the upper end portion of the base portion 152A of the intermediate connection component 152 is in proximity and opposition to the front wall portion 125B of the cover portion 125 at the opposing position L1 (see FIG. 5), and the lower end portion 151b of the main body portion 151A of the slide lock component 151 is in proximity and opposition to the lower protrusion portion 111D of the base portion 111 of the plug main body 110 at the opposing position L2 (see FIG. 5). For this reason, even when the user presses the lower portion of the main body portion 151A of the slide lock component 151 with a finger in the locked state, the locked state of the claw portion 153A of the opening / closing lever component 153 and the claw portion 122 of the lid body 120 is not released and the lid body 120 does not open. In the front view when the claw portion 153A of the opening / closing lever component 153 and the claw portion 122 of the lid body 120 are in the locked state, the opposing position L1 is located on the side where the claw portion 153A of the opening / closing lever component 153 is disposed with respect to the axis SH, and the opposing position L2 is located on the side opposite to the side where the claw portion 153A of the opening / closing lever component 153 is disposed with respect to the axis SH. And the orientation of the surface of the front wall portion 125B of the cover portion 125 on the side facing the base portion 152A of the intermediate connection component 152 (that is, the rearward direction) and the orientation of the surface of the lower protrusion portion 111D of the base portion 111 of the plug main body 110 on the side facing the lower end portion 151b of the main body portion 151A of the slide lock component 151 (that is, the forward direction) are opposite to each other. Also, when the lock member LM of the plug body 100 is in the locked state, the position holding protrusion portion 152C of the intermediate connection component 152 is located above the position holding protrusion portion 153G of the opening / closing lever component 153 and is in contact with the position holding protrusion portion 153G of the opening / closing lever component 153. Also, when the lock member LM of the plug body 100 is in the locked state, the intermediate connection component 152 is not exposed (that is, the intermediate connection component 152 is hidden by the cover portion 125 and the slide lock component 151).)(See Fig. 5).

[0053] When the user of the beverage container 1 opens the lid 120 to drink the beverage in the beverage container 1, the user first needs to release the locked state of the lock member LM of the plug body 100. To do this, the user first places a finger on the finger receiving portion 151a of the slide lock part 151 and presses down the slide lock part 151 with the finger to slide the slide lock part 151 from the upper position to the lower position. At this time, as shown in FIG. 13, the intermediate connecting part 152 also slides downward together with the slide lock part 151. As shown in FIG. 13, when the intermediate connecting part 152 slides downward, the position holding projection 152C of the intermediate connecting part 152 rides over the position holding projection 153G of the opening / closing lever part 153 while abutting against the position holding projection 153G of the opening / closing lever part 153 and comes to be located below the position holding projection 153G of the opening / closing lever part 153. As a result, the upper end part of the base part 152A of the intermediate connecting part 152 is in a state of not facing the front wall part 125B of the cover part 125, and the lower end part 151b of the main body part 151A of the slide lock part 151 is also in a state of not facing the lower projection 111D of the base part 111 of the plug body 110. At this time, the upper end part of the base part 152A of the intermediate connecting part 152 is exposed (that is, the upper end part of the base part 152A of the intermediate connecting part 152 is not hidden by the cover part 125 and the slide lock part 151 and is visible.) (see FIGS. 4 and 13). Then, when the user places a finger on the lower part of the main body part 151A of the slide lock part 151 and pushes the lower part of the main body part 151A of the slide lock part 151 backward against the biasing force of the forward biasing coil spring Sf, the slide lock part 151, the intermediate connecting part 152, and the opening / closing lever part 153 rotate about the axis SH, and the claw part 153A of the opening / closing lever part 153 falls forward, and the claw part 122 of the lid 120 comes off from the claw part 153A of the opening / closing lever part 153 (see FIG. 14). As described above, since the lid 120 is biased backward by the torque hinge spring Sp, at the moment when the claw part 122 of the lid 120 comes off from the claw part 153A of the opening / closing lever part 153, the lid 120 rotates backward about the hinge pin Pn and the lid 120 is in an open state.Then, after the user releases the finger from the lower part of the main body 151A of the slide lock component 151, the user grips the vacuum double-wall container 10 portion of the beverage container 1 and lifts the beverage container 1, bringing the upper cylindrical wall portion 112 of the plug body 110 to the mouth, and then directly lifts the beverage container 1 to drink the beverage in the beverage container 1.

[0054] Then, when the user finishes drinking the beverage, the user closes the lid body 120. When the claw portion 122 of the lid body 120 abuts against the claw portion 153A of the opening / closing lever component 153 and is pushed in as it is during the closing of the lid body 120, the claw portion 153A of the opening / closing lever component 153 slightly rotates forward about the shaft SH against the biasing force of the forward biasing coil spring Sf. Then, when the claw portion 122 of the lid body 120 comes to be located below the claw portion 153A of the opening / closing lever component 153, the claw portion 153A of the opening / closing lever component 153 is biased rearward by the biasing force of the forward biasing coil spring Sf. As a result, the claw portion 122 of the lid body 120 is locked to the claw portion 153A of the opening / closing lever component 153. Then, the user places a finger on the finger receiving portion 151a of the slide lock component 151 and pushes up the slide lock component 151 with the finger to slide the slide lock component 151 from the lower position to the upper position. At this time, the intermediate connecting component 152 also slides upward together with the slide lock component 151. When the intermediate connecting component 152 slides upward, the position holding protrusion 152C of the intermediate connecting component 152 rides over the position holding protrusion 153G of the opening / closing lever component 153 while abutting against the position holding protrusion 153G of the opening / closing lever component 153 and comes to be located above the position holding protrusion 153G of the opening / closing lever component 153. In this way, the plug body 100 is again brought into the locked state.

[0055] <Features of the beverage container according to the embodiment of the present invention> (1) In the beverage container 1 according to the embodiment of the present invention, when the plug body 100 is in the locked state, the slide lock component 151 is located at the upper position. When the user pushes in the lower end portion of the slide lock component 151 with a finger, the locking state of the claw portion 153A of the opening / closing lever component 153 and the claw portion 122 of the lid body 120 is released, and it is possible to prevent the lid body 120 from being in the open state at the opposing position L1. The opposing position L1 is a position where the upper end portion of the base portion 152A of the intermediate connecting component 152 is in close proximity to and opposed to the front wall portion 125B of the cover portion 125, and is located on the side where the claw portion 153A of the opening / closing lever component 153 is disposed with respect to the axis SH in a front view. Therefore, in this beverage container 1, even if a large load in the direction of opening the lid body 120 is applied to the lid body 120, it is possible to reduce the risk of deformation or breakage of the claw portion 122 of the lid body 120 and the claw portion 153A of the opening / closing lever component 153.

[0056] (2) In the beverage container 1 according to the embodiment of the present invention, when the slide lock component 151 slides from the upper position to the lower position, the locking state of the lock member LM of the plug body 100 can be released. Further, in this beverage container 1, when the slide lock component 151 slides from the lower position to the upper position, the plug body 100 can be brought into the locked state. Therefore, in this beverage container 1, compared to the case where the slide lock component 151 slides from the lower position to the upper position and the locking state of the lock member LM of the plug body 100 is released, or the case where the slide lock component 151 slides from the upper position to the lower position and the plug body 100 is brought into the locked state, the operation direction of the slide lock component 151 can be intuitively recognized by the user.

[0057] (3) In the beverage container 1 according to the embodiment of the present invention, the direction of the surface of the front wall portion 125B of the cover portion 125 facing the base portion 152A of the intermediate connecting component 152 and the direction of the surface of the lower protrusion portion 111D of the base portion 111 of the plug body 110 facing the lower end portion 151b of the main body portion 151A of the slide lock component 151 are opposite to each other. Therefore, in this beverage container 1, when the lock member LM of the plug body 100 is in the locked state, a load for rotating the lock member LM about the axis SH is unexpectedly applied and the lock member LM rotates, thereby unexpectedly releasing the locked state. This can be prevented by the cover portion 125 disposed at the rotation destination of the intermediate connecting component 152 and the lower protrusion portion 111D of the base portion 111 of the plug body 110 disposed at the rotation destination of the slide lock component 151.

[0058] (4) In the beverage container 1 according to the embodiment of the present invention, the intermediate connecting component 152 is different in color from the slide lock component 151. Further, the upper end portion of the base portion 152A of the intermediate connecting component 152 is exposed when the locked state of the lock member LM of the plug body 100 is released. Therefore, in this beverage container 1, the user can clearly recognize whether the lock member LM is in the locked state or the locked state of the lock member LM has been released, and can prevent as much as possible that the locked state of the lock member LM remains released after the lid body 120 is closed.

[0059] (5) In the beverage container 1 according to the embodiment of the present invention, the slide lock component 151 is maintained in the upper position or the lower position by the position holding protrusion portion 152C of the intermediate connecting component 152. Therefore, in this beverage container 1, it is possible to prevent as much as possible the lock member LM from unexpectedly entering the locked state and the locked state of the lock member LM from being released.

[0060] <Modification example> (A) In the beverage container 1 according to the previous embodiment, the user places a finger on the finger receiver 151a of the slide lock component 151 and presses down the slide lock component 151 with the finger to slide the slide lock component 151 from the upper position to the lower position. Then, by pushing the lower part of the main body 151A of the slide lock component 151 backward, the claw part 122 of the lid body 120 can be rotated about the axis SH. In other words, the operation on the opening / closing lever component 153 was performed via the slide lock component 151. However, the operation on the opening / closing lever component 153 does not necessarily have to be performed via the slide lock component 151.

[0061] (B) In the beverage container 1 according to the previous embodiment, in a front view of the state where the claw part 122 of the lid body 120 is locked to the claw part 153A of the opening / closing lever component 153, when the lock member LM is operated along the direction from the claw part 153A of the opening / closing lever component 153 toward the axis SH, the locked state of the lock member LM of the plug body 100 is released. When the lock member LM is operated along the direction from the axis SH toward the claw part 153A of the opening / closing lever component 153, the lock member LM of the plug body 100 was in the locked state. However, in a front view of the state where the claw part 122 of the lid body 120 is locked to the claw part 153A of the opening / closing lever component 153, when the lock member LM is operated along the direction from the claw part 153A of the opening / closing lever component 153 toward the axis SH, the lock member LM of the plug body 100 may be in the locked state, or when the lock member LM is operated along the direction from the axis SH toward the claw part 153A of the opening / closing lever component 153, the locked state of the lock member LM of the plug body 100 may be released.

[0062] (C) In the beverage container 1 according to the previous embodiment, when the plug body 100 is in the locked state, the lower end portion 151b of the main body portion 151A of the slide lock component 151 was in the facing position L2 and was closely opposed to the lower protrusion portion 111D of the base portion 111 of the plug main body 110. However, the lower end portion 151b of the main body portion 151A of the slide lock component 151 does not necessarily have to be closely opposed to the lower protrusion portion 111D of the base portion 111 of the plug main body 110 (for example, the lower protrusion portion 111D of the base portion 111 of the plug main body 110 may be deleted). That is, when the plug body 100 is in the locked state, at the facing position L1, it is only necessary that the upper end portion of the base portion 152A of the intermediate connection component 152 and the front wall portion 125B of the cover portion 125 are closely opposed, and the lower part of the main body portion 151A of the slide lock component 151 may be prevented from being pushed in by the user.

[0063] (D) In the beverage container 1 according to the previous embodiment, when the lock member LM of the plug body 100 is in the locked state, the orientation of the surface of the front wall portion 125B of the cover portion 125 on the side facing the base portion 152A of the intermediate connection component 152 and the orientation of the surface of the lower protrusion portion 111D of the base portion 111 of the plug main body 110 on the side facing the lower end portion 151b of the main body portion 151A of the slide lock component 151 were opposite to each other, but they do not necessarily have to be opposite to each other.

[0064] (E) In the beverage container 1 according to the previous embodiment, when the plug body 100 is in the locked state, the intermediate connection component 152 was in the facing position L1 and was closely opposed to the front wall portion 125B of the cover portion 125, and the slide lock component 151 was in the facing position L2 and was closely opposed to the lower protrusion portion 111D of the base portion 111 of the plug main body 110. However, when the plug body 100 is in the locked state, the slide lock component 151 may be in the facing position L1 and be closely opposed to the front wall portion 125B of the cover portion 125, and the intermediate connection component 152 may be in the facing position L2 and be closely opposed to the lower protrusion portion 111D of the base portion 111 of the plug main body 110.

[0065] (F) In the beverage container 1 according to the previous embodiment, the intermediate connecting component 152 had a different color from the slide lock component 151. However, only the upper end portion of the base body portion 152A of the intermediate connecting component 152 may have a different color from the slide lock component 151. Alternatively, the intermediate connecting component 152 and the slide lock component 151 may have the same color. When the upper end portion of the base body portion 152A of the intermediate connecting component 152 has a different color from the slide lock component 151, or when the intermediate connecting component 152 and the slide lock component 151 have the same color, a pattern, decoration, or the like may be applied to the upper end portion of the base body portion 152A of the intermediate connecting component 152.

[0066] Also, when the locking state of the locking member LM of the plug body 100 was released, the intermediate connecting component 152 was exposed, but the intermediate connecting component 152 may not be exposed.

[0067] (G) In the beverage container 1 according to the previous embodiment, when the opening / closing lever component 153 rotated about the axis SH, the intermediate connecting component 152 also rotated together about the axis SH. However, when the opening / closing lever component 153 rotates about the axis SH, the intermediate connecting component 152 may be designed not to rotate together about the axis SH.

[0068] (H) In the beverage container 1 according to the previous embodiment, when the locking member LM of the plug body 100 was in the locked state, the claw portion 153A of the opening / closing lever component 153 and the claw portion 122 of the lid body 120 were located above the axis SH. However, the claw portion 153A of the opening / closing lever component 153 and the claw portion 122 of the lid body 120 may be designed to be located below the axis SH.

[0069] (I) In the beverage container 1 according to the previous embodiment, the fitting projection portion 152D of the intermediate connecting component 152 was fitted into the concave portion 151c of the slide lock component 151, and the slide lock component 151 and the intermediate connecting component 152 were connected in an interlocking manner. However, the slide lock component 151 and the intermediate connecting component 152 may be integrally formed.

[0070] (J) In the beverage container 1 according to the previous embodiment, the handle 200 was configured, but the handle 200 may not be configured.

[0071] (K) In the beverage container 1 according to the previous embodiment, the slide lock component 151 was slidable in the vertical direction along the long hole HL1 of the wing portion 151B. That is, the slidable distance of the slide lock component 151 and the intermediate connection component 152 in the downward direction was defined by the vertical length of the long hole HL1 of the wing portion 151B. However, the slidable distance of the slide lock component 151 and the intermediate connection component 152 in the downward direction may be defined by the height position of the bottom wall portion 153E of the opening / closing lever component 153. That is, when the slide lock component 151 and the intermediate connection component 152 slide downward and the outer slide portion 152E of the intermediate connection component 152 abuts against the bottom wall portion 153E of the opening / closing lever component 153, it may be the lowest height position in the vertical direction of the slide lock component 151 and the intermediate connection component 152.

[0072] (L) In the beverage container 1 according to the previous embodiment, the cover portion 125 was attached to the lid body 120. However, the cover portion 125 and the lid body 120 may be integrally formed. In such a case, all of the cover portion 125 may be integrally formed with the lid body 120, or only the front wall portion 125B of the cover portion 125 may be integrally formed with the lid body 120.
