[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-173542 Summary of the Invention [Problem to be solved by the invention]

[0004] When carrying a beverage container equipped with the above-described stopper, a user holds the handle with one hand. When attempting to open the lid while holding the handle with one hand, the user holds the beverage container with the other hand and operates the operating part. Therefore, with the above-described stopper, if the handle is held with one hand and the other hand is occupied (for example, the other hand is holding luggage), it becomes difficult to open the lid, making it difficult to use.

[0005] An object of the present invention is to provide a stopper whose lid can be opened while holding the handle with one hand without changing the gripping hand. [Means for solving the problem]

[0006] The plug according to the present invention comprises: a plug body having a latched portion and a discharge port; a cover that covers the discharge port in an openable and closable manner; a handle provided on the lid; a locking mechanism that has a locking portion that can be locked to the locked portion, and that can switch between a locked state in which the locking portion is locked to the locked portion and the lid body is in a closed state, and a released state in which the locking state is released and the lid body can be in an open state by being operated; an operation unit for operating the locking mechanism so that the locking mechanism changes from the locked state to the released state, The operating portion is provided on the cover so as to be located inside the handle.

[0007] According to the above configuration, the operating part for operating the locking mechanism is provided on the lid so as to be located inside the handle, so that with this plug, the lid can be opened while holding the handle with one hand without changing the hand holding it.

[0008] In the present invention, a connecting portion connected to the locking mechanism and the operating portion and provided inside the lid, It is preferable that the operating portion operates the locking mechanism via the connecting portion.

[0009] According to the above configuration, it is possible to maximize the degree of freedom in designing the locking mechanism, the operating portion, and the lid.

[0010] In the present invention, Preferably, the operating section can be switched between an operable state in which the locking mechanism is operable and an inoperable state in which the locking mechanism is inoperable.

[0011] With this configuration, the user can switch the operating part to an inoperable state except when trying to open the lid, which makes it possible to prevent the lid from being opened accidentally due to a finger or other object accidentally coming into contact with the operating part.

[0012] In the present invention, It is preferable that the operating portion is switched from the operable state to the inoperable state when the cover body transitions from the open state to the closed state.

[0013] According to the above configuration, it is possible to prevent forgetting to switch the operating section from an operable state to an inoperable state after the cover is closed.

[0014] In the present invention, a valve portion that closes the discharge port when the lid body is in the closed state, It is preferable that the valve portion biases the lid body in a direction to open the lid body when the locking mechanism is in the released state.

[0015] According to the above configuration, when the locking mechanism is switched from the locked state to the released state, the lid can be automatically opened by the biasing force of the valve portion.

[0016] The beverage container according to the present invention comprises: The plug described above; and a container to which the stopper is attached.

[0017] According to the above configuration, the above-described stopper is attached to the beverage container, and therefore the beverage container can achieve the above-described effects. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] <Configuration of beverage container according to an embodiment of the present invention> As shown in Figures 1 and 4, a beverage container 1 according to an embodiment of the present invention is composed of a vacuum double container 10 and a stopper 100. The beverage container 1 is assembled by attaching the stopper 100 to the vacuum double container 10. Each of these components will be described in detail below.

[0020] 1. Vacuum double container The vacuum double vessel 10 is a vessel made of metal such as stainless steel, and is mainly formed of a bottomed inner cylinder 11 (see FIG. 4) and a bottomed outer cylinder 12 (see FIGS. 1 and 4). Specifically, the upper end of the inner cylinder side wall portion 11A of the inner cylinder 11 and the upper end of the outer cylinder side wall portion 12A of the outer cylinder 12 are joined together so that an insulating space is formed between the inner cylinder 11 and the outer cylinder 12, and then the insulating space is evacuated, thereby forming the vacuum double vessel 10.

[0021] The inner cylinder 11 is mainly formed by an inner cylinder side wall portion 11A (see FIG. 4) and an inner cylinder bottom wall portion (not shown). The inner cylinder side wall portion 11A has a substantially cylindrical shape. The inner cylinder bottom wall portion has a central portion that rises in a spherical shape toward the opening side, and corners that are concave arc-shaped. The inner cylinder bottom wall portion is located below the inner cylinder side wall portion 11A.

[0022] As shown in Figures 1 and 4, the outer cylinder 12 is mainly formed by an outer cylinder side wall portion 12A, an outer cylinder bottom wall portion (not shown), and an externally threaded portion 12B. As shown in Figure 1, the outer cylinder side wall portion 12A has a substantially cylindrical shape. The outer cylinder bottom wall portion has a substantially disk shape and is joined to the lower end portion of the outer cylinder side wall portion 12A. As shown in Figure 4, the externally threaded portion 12B is formed on the outer peripheral surface of the upper end portion of the outer cylinder side wall portion 12A. When the plug 100 is attached to the vacuum double container 10, this externally threaded portion 12B can be threadedly engaged with the internally threaded portion CV3 of the plug body cover member CV of the plug 100 (see Figure 4).

[0023] 2.Bung body 1 to 4, the plug 100 is mainly composed of a plug body 110, an annular packing PK, a plug body cover member CV, a lid body 120, an operating mechanism 124, and a hinge mechanism 140. Each of these components will be described in detail below.

[0024] (1) Plug body As shown in Figures 2, 4, and 5, the plug body 110 is mainly composed of a drinking spout 111, a front claw receiver 112, a front protrusion 113, a rear claw receiver 114, an annular rib 115, and a packing attachment portion 116. The plug body 110 is attached to the plug body cover member CV as shown in Figures 2 and 4. As shown in Figures 2, 4, and 5, the drinking spout 111 has a generally cylindrical shape with its upper end sloping downward from the front to the rear. The drinking spout 111 functions as a drinking spout for a beverage contained in the vacuum double container 10, and the interior of the drinking spout 111, together with the interior of the packing attachment portion 116, functions as a beverage passage PD via a lower opening 111a of the drinking spout 111 (see Figures 2, 4, and 5). As shown in FIG. 4, when the lid 120 is in the closed state, the gasket mounting portion 121C of the lid body 121 of the lid 120 and the gasket 123 are positioned inside the spout 111, and the gasket 123 abuts against the lower end of the spout 111 to close the lower opening 111a of the spout 111. As shown in FIGS. 2, 4, and 5, the front claw receiver 112 has a box shape with an open front and is formed at the front end of the spout 111. As shown in FIG. 4, the front claw receiver 112 is engaged with the claw OP5 of the opening / closing lever part OP of the locking mechanism LM of the operating mechanism 124. As shown in FIGS. 2 and 5, a pair of front protrusions 113 are formed on the left and right sides of the front claw receiver 112. As shown in FIGS. 2 and 4, when the plug body 110 is attached to the plug body cover member CV, the front protrusion 113 rides on the base portion CV6 of the plug body cover member CV. As shown in FIGS. 2, 4, and 5, the rear claw receiving portion 114 is formed at the rear end of the spout portion 111. As shown in FIG. 4, when the plug body 110 is attached to the plug body cover member CV, the rear claw receiving portion 114 engages with the claw portion CV4 of the plug body cover member CV. As shown in FIGS. 4 and 5, the annular rib 115 is a rib for determining the upper end position of the annular packing PK. It extends outward from near the boundary between the spout portion 111 and the packing attachment portion 116 and has a generally annular shape. The packing attachment portion 116 has a generally cylindrical shape and extends downward from the lower end of the spout portion 111, as shown in FIG. 4.As described above, the interior of the packing attachment part 116 functions as the beverage passage PD together with the interior of the drinking spout part 111. Also, as shown in Figure 4, an annular packing PK is attached to the outer peripheral surface of the packing attachment part 116.

[0025] (2) Annular packing The annular packing PK is a rubber / elastomer member having a generally annular shape. As shown in Fig. 4, when the plug 100 is attached to the vacuum double container 10, the annular packing PK serves to seal the gap between the inner cylinder side wall 11A of the inner cylinder 11 of the vacuum double container 10 and the packing attachment portion 116 of the plug body 110.

[0026] (3) Plug body cover member As shown in FIGS. 1 to 4 and 6, the plug body cover member CV is primarily composed of an upper wall portion CV1, a side wall portion CV2, an internal thread portion CV3, a claw portion CV4, a cover portion-side connecting portion CV5, and a base portion CV6. As shown in FIGS. 2, 4, and 6, the upper wall portion CV1 constitutes the upper wall of the plug body cover member CV and has a generally circular shape. As shown in FIG. 6, the upper wall portion CV1 is formed with a plug body insertion port CV1a for inserting the plug body 110. As shown in FIGS. 1 to 4 and 6, the side wall portion CV2 has a generally cylindrical shape and extends downward from the outer edge of the upper wall portion CV1. As shown in FIGS. 4 and 6, the internal thread portion CV3 is formed on the inner circumferential surface of the side wall portion CV2. As described above, when the plug 100 is attached to the vacuum double container 10, the female thread portion CV3 can be threadedly engaged with the male thread portion 12B of the outer tube 12 of the vacuum double container 10. As shown in FIGS. 4 and 6, the claw portion CV4 is formed on the lower side of the rear end portion of the upper wall portion CV1. As described above, when the plug body 110 is attached to the plug body cover member CV, the claw portion CV4 engages with the rear claw receiving portion 114 of the plug body 110. The cover side connecting portion CV5 is one of the components that constitute the hinge mechanism 140, and as shown in FIGS. 2, 4, and 6, extends rearward and upward (diagonally) from the rear end portion of the upper wall portion CV1. As shown in FIGS. 4 and 6, the cover side connecting portion CV5 has a through hole CV5a formed therein through which the hinge pin Pn1 is inserted. As shown in Fig. 6, the base portions CV6 extend rearward from the front end of the upper wall portion CV1 so as to be located on both the left and right sides of the front end of the plug body insertion opening CV1a. As shown in Fig. 6, the upper surface of the base portion CV6 is located below the upper surface of the upper wall portion CV1. As described above, when the plug body 110 is attached to the plug body cover member CV, the front protrusions 113 of the plug body 110 ride on the base portions CV6.

[0027] (4) Lid 1 to 4, the lid body 120 is mainly composed of a lid main body 121, a lid main body cover member 122, and a packing 123. Each of these components will be described in detail below.

[0028] (4-1) Lid bodyAs shown in FIGS. 2 to 4, 7, and 8, the lid main body 121 is primarily formed of an upper wall portion 121A, a side wall portion 121B, a packing mounting portion 121C, a lid main body side connecting portion 121D, an upper pin receiving portion 121E, a front pin receiving portion 121F, and a spring installation portion 121G. As shown in FIGS. 2 and 4, the lid main body 121 is attached to a lid main body cover member 122. As shown in FIGS. 4, 7, and 8, the upper wall portion 121A forms the upper wall of the lid main body 121 and slopes downward from the front to the rear. As shown in FIGS. 4 and 8, the upper wall portion 121A has a recess that is recessed downward from the middle portion in the front-to-rear direction to the rear end. As shown in FIG. 4, a spring installation portion 121G is formed on the upper surface of this recess, and a packing mounting portion 121C is formed on the lower surface of the recess. As shown in Figures 4, 7, and 8, the side wall portion 121B extends downward from the outer edge of the upper wall portion 121A. As described above, the packing attachment portion 121C is formed on the underside of the recess in the upper wall portion 121A and has a substantially cylindrical shape. As shown in Figure 4, a packing 123 is attached to the outer peripheral surface of the packing attachment portion 121C. As shown in Figures 2, 3, 7, and 8, a pair of lid body side connecting portions 121D are formed on the left and right sides at the rear end of the lid body 121. As shown in Figures 7 and 8, the lid body side connecting portion 121D has a through hole 121d formed therein, through which the hinge pin Pn1 is inserted. 2 and 3, the lid main body side connecting portion 121D is disposed outside the cover portion side connecting portion CV5 of the plug main body cover member CV and inside the pin receiving portion 122E of the lid main body cover member 122 (in other words, it is sandwiched between the cover portion side connecting portion CV5 of the plug main body cover member CV and the pin receiving portion 122E of the lid main body cover member 122), and constitutes a part of the hinge mechanism 140. As shown in FIGS. 7 and 8, a pair of upper pin receiving portions 121E are formed on the left and right sides of the upper end of the top wall portion 121A. As shown in FIGS. 7 and 8, a through hole 121e through which the lever pin Pn2 is inserted is formed in the upper pin receiving portion 121E. As shown in FIGS. 7 and 8, a pair of front pin receiving portions 121F are formed on the left and right sides of the front end of the side wall portion 121B.7 and 8, a through-hole 121f through which the pivot pin Pn3 is inserted is formed in the upper end of the front pin receiving portion 121F. As described above, the spring installation portion 121G is formed on the upper surface of the recess in the upper wall portion 121A and has a substantially cylindrical shape. As shown in FIG. 4, one end of the front coil spring Sf2 is disposed inside the spring installation portion 121G.

[0029] (4-2) Lid body cover member As shown in FIGS. 1 to 4, the lid main body cover member 122 is mainly composed of an upper wall portion 122A, a side wall portion 122B, a bottom wall portion 122C, a handle 122D, and a pin receiving portion 122E. As shown in FIGS. 1, 3, and 4, the upper wall portion 122A constitutes the upper wall of the lid main body cover member 122 and has a generally disk shape. As shown in FIGS. 1 to 4, the side wall portion 122B extends downward from the outer edge of the upper wall portion 122A and has a generally cylindrical shape. An opening is formed at the rear end of the side wall portion 122B for fitting the slide portion SP of the operation mechanism 124 (see FIGS. 3 and 4). The role of a blocking portion 122b (see FIG. 4) located above this opening in the side wall portion 122B will be described later. As shown in FIGS. 1 to 3, the bottom wall 122C extends outward from the lower edge of the side wall 122B. When the lid 120 is closed, the lower surface of the bottom wall 122C faces the upper surface of the upper wall CV1 of the plug body cover member CV. The handle 122D is provided to allow a user to carry the beverage container 1 by hand, and is generally U-shaped on the right side (see FIGS. 1 to 4). As shown in FIGS. 1 to 4, one end of the handle 122D is connected to the rear end of the upper wall 122A, and the other end of the handle 122D is connected to the rear end of the bottom wall 122C. An opening is formed at the lower end and in the left-right middle of the handle 122D, exposing a portion of the cover-side connecting portion CV5 of the plug body cover member CV (see FIG. 1). As shown in Figures 1 to 3, a pair of pin receiving portions 122E are formed on the left and right ends of handle 122D. As shown in Figures 1 to 3, pin receiving portion 122E is formed with a through-hole 122e through which hinge pin Pn1 is inserted. Note that pin receiving portion 122E constitutes a part of hinge mechanism 140 as shown in Figures 1 to 3.

[0030] (4-3) Gasket Gasket 123 is a flexible member made of rubber or elastomer, and as shown in Figures 2 and 8, has a generally cylindrical shape with a bottom. As described above, gasket 123 is attached to the outer peripheral surface of gasket attachment portion 121C of lid body 121. Also, as described above, when lid body 120 is in the closed state, gasket 123, together with gasket attachment portion 121C of lid body 121, is located inside spout 111 of plug body 110 and abuts against the lower end of spout 111 of plug body 110. At this time, gasket 123 is compressed due to its flexibility, blocking lower opening 111a of spout 111 of plug body 110 and keeping plug body 110 and lid body 120 watertight. Then, when the claw portion OP5 of the opening / closing lever part OP of the locking mechanism LM of the operating mechanism 124 is released from its engagement with the front claw receiving portion 112 of the plug body 110, allowing the lid body 120 to be opened, the compressed state of the packing 123 is released. Then, due to the repulsive force (biasing force) of the packing 123 when the compressed state of the packing 123 is released, the lid body 120 is biased in the opening direction and rotates in the opening direction around the hinge pin Pn1. Note that at this time, the lid body 120 is not in a fully open state, but is in an open state to the extent that the claw portion OP5 of the opening / closing lever part OP of the locking mechanism LM of the operating mechanism 124 is positioned above the front claw receiving portion 112 of the plug body 110 (see FIG. 13).

[0031] (5) Operation mechanism 4, 7, and 8, the operation mechanism 124 is disposed inside the lid 120 (between the lid main body 121 and the lid main body cover member 122), and is mainly composed of a slide part SP, a connecting part CP, a lever pin Pn2, a rear coil spring Sf1, and a locking mechanism LM. Each of these components will be described in detail below.

[0032] (5-1) Slide section As shown in Figures 3, 4, 7, and 8, the slide portion SP is mainly composed of a vertical slide member VS and a horizontal slide member HS. As shown in Figures 3 and 4, the slide portion SP is fitted into an opening formed at the rear end of the side wall portion 122B of the lid main body cover member 122. The slide portion SP is provided on the lid body 120 so as to be positioned inside the handle 122D of the lid main body cover member 122, and a portion of the slide portion SP is exposed so that it can be operated by the user. Each component of the slide portion SP will be described in detail below.

[0033] (5-1-1) Vertical sliding member The vertical slide member VS is attached to the horizontal slide member HS so as to be slidable in a diagonal direction (in other words, in the biasing direction of the rear coil spring Sf1 and the direction opposite to this biasing direction), and as shown in FIGS. 4 and 7 to 9, is mainly formed of a base portion VS1, a finger receiving portion VS2, a first extension wall portion VS3, a second extension wall portion VS4, and a spring installation portion VS5. As shown in FIGS. 4 and 7 to 9, the base portion VS1 is a substantially rectangular plate member. When the vertical slide member VS is in the upper position (i.e., when the slide portion SP is in the locked state), the upper end of the base portion VS1 closely faces the blocking portion 122b of the side wall portion 122B of the lid main body cover member 122 (see FIG. 4). On the other hand, when the slide lock component 151 is in the lower position (i.e., when the slide portion SP is in the unlocked state), the upper end of the base portion VS1 does not closely face the blocking portion 122b of the side wall portion 122B of the lid body cover member 122 (see FIG. 11). As shown in FIGS. 4, 7, and 9, the finger receiving portion VS2 extends rearward from the vertically intermediate portion of the base portion VS1. The finger receiving portion VS2 functions as a portion on which the user places his or her finger when operating the vertical slide member VS. As shown in FIGS. 4, 8, and 9, the first extension wall portion VS3 extends forward from the vertically intermediate portion of the base portion VS1. As shown in FIGS. 8 and 9, the second extension wall portion VS4 extends laterally from the front end of the first extension wall portion VS3. As shown in FIGS. 4, 8, and 9, the spring installation portion VS5 extends downward from the underside of the first extension wall portion VS3. One end of the rear coil spring Sf1 is fitted into this spring installation portion VS5 (see FIGS. 4 and 8).

[0034] (5-1-2) Horizontal sliding member The horizontal slide member HS is a member that can slide in the front-rear direction and, as shown in FIGS. 4, 7, 8, and 10, is mainly formed of a pressing portion HS1, a pin receiving portion HS2, a bottom wall portion HS3, a front wall portion HS4, a rear wall portion HS5, and a spring installation portion HS6. The pressing portion HS1 has a generally concave shape in plan view (see FIGS. 7 and 8). As shown in FIG. 4, the pressing portion HS1 is located in front of the blocking portion 122b of the side wall portion 122B of the lid main body cover member 122. As shown in FIGS. 4 and 7, the pressing portion HS1 can come into contact with the pin receiving portion CP2 of the connecting part CP. Therefore, when the horizontal slide member HS slides forward, the pressing portion HS1 presses the pin receiving portion CP2 of the connecting part CP forward, causing the connecting part CP to rotate forward about the lever pin Pn2. The pressing portion HS1 is indirectly biased rearward by the front coil spring Sf2 via the opening / closing lever part OP and the connecting part CP (see FIG. 4). As shown in FIGS. 4, 7, 8, and 10, a pair of pin receiving portions HS2 are formed on the left and right sides below the pressing portion HS1 and extend in the front-to-rear direction. As shown in FIGS. 4, 8, and 10, an elongated hole HS2a through which the lever pin Pn2 is inserted is formed at the upper end of the pin receiving portion HS2. Since the lever pin Pn2 is fixed within the cover body 120, the lateral sliding member HS can slide in the front-to-rear direction along the elongated hole HS2a. As shown in FIGS. 4, 8, and 10, the bottom wall portion HS3 extends inward from the lower end of the pin receiving portion HS2. As shown in Figures 4 and 10, the front wall portions HS4 are formed as a pair on the left and right, and extend obliquely upward (in the biasing direction of the rear coil spring Sf1) from the left and right portions of the front end of the bottom wall portion HS3. As shown in Figures 4 and 10, the rear wall portion HS5 extends obliquely upward (in the biasing direction of the rear coil spring Sf1) from the rear end of the bottom wall portion HS3 to a height position at the vertical middle portion of the pin receiving portion HS2. As shown in Figures 4 and 10, the spring installation portion HS6 extends upward from the upper surface of the bottom wall portion HS3 so as to be located between the pair of left and right front wall portions HS4. One end of the rear coil spring Sf1 is fitted into this spring installation portion HS6 (see Figures 4 and 8).

[0035] Here, we will explain the positional relationship between the vertical sliding member VS and the horizontal sliding member HS when the vertical sliding member VS is attached to the horizontal sliding member HS. The base portion VS1 of the vertical sliding member VS is located between the pair of left and right pin receiving portions HS2 of the horizontal sliding member HS, above the bottom wall portion HS3 of the horizontal sliding member HS, behind the front wall portion HS4 of the horizontal sliding member HS, and in front of the rear wall portion HS5 of the horizontal sliding member HS. The first extension wall portion VS3 and the spring installation portion VS5 of the vertical sliding member VS are located between the pair of left and right front wall portions HS4 of the horizontal sliding member HS. The second extension wall portion VS4 of the vertical sliding member VS is located in front of the front wall portion HS4 of the horizontal sliding member HS (see FIG. 4). In this way, the vertical sliding member VS can slide diagonally downward. The vertical sliding member VS can slide diagonally downward until the finger receiving portion VS2 contacts the upper end of the rear wall portion HS5 of the vertical sliding member VS (see FIG. 11).

[0036] (5-2) Connecting parts As shown in FIGS. 4, 7, and 8, the connecting part CP is mainly composed of a pressing part CP1 and a pin receiving part CP2. The pressing part CP1 is a plate member having a generally concave shape in a plan view (see FIGS. 7 and 8). As shown in FIGS. 4 and 7, the pressing part CP1 and the pressed part OP1 of the opening / closing lever part OP of the locking mechanism LM come into contact with each other, thereby connecting the connecting part CP and the locking mechanism LM. The pressing part CP1 is indirectly biased upward by the front coil spring Sf2 of the locking mechanism LM via the opening / closing lever part OP of the locking mechanism LM (see FIG. 4). When the connecting part CP rotates forward around the lever pin Pn2, the pressing part CP1 presses the pressed part OP1 of the opening / closing lever part OP of the locking mechanism LM downward (see FIG. 12). As shown in FIGS. 4, 7, and 8, the pin receiving portions CP2 are a pair of left and right portions extending downward from the rear end and left and right end portions of the pressing portion CP1. As shown in FIGS. 4 and 7, the pin receiving portions CP2 are disposed outside the pin receiving portion HS2 of the lateral slide member HS of the sliding portion SP and inside the upper pin receiving portion 121E of the lid main body 121. In other words, the pin receiving portions CP2 are sandwiched between the pin receiving portion HS2 of the lateral slide member HS of the sliding portion SP and the upper pin receiving portion 121E of the lid main body 121. As shown in FIG. 8, a through-hole CP2a through which the lever pin Pn2 is inserted is formed at the lower end of the pin receiving portion CP2. As shown in FIGS. 4 and 7, the pin receiving portions CP2 and the pressing portion HS1 of the lateral slide member HS of the sliding portion SP come into contact with each other, thereby connecting the connecting part CP and the sliding portion SP. When the horizontal slide member HS of the slide part SP slides forward, the pin receiving part CP2 is pressed forward by the pressing part HS1 of the horizontal slide member HS of the slide part SP, and the connecting part CP rotates forward about the lever pin Pn2 against the biasing force of the front coil spring Sf2 of the locking mechanism LM (see FIG. 12). As described above, when the connecting part CP rotates forward about the lever pin Pn2, the pressing part CP1 presses downward the pressed part OP1 of the opening / closing lever part OP of the locking mechanism LM, and the slide part SP can operate the locking mechanism LM via the connecting part CP.

[0037] (5-3) Lever pin 4 and 7, the lever pin Pn2 is inserted, from the outside, through the through hole 121e of the upper pin receiving portion 121E of the lid main body 121, the through hole CP2a of the pin receiving portion CP2 of the connecting part CP, and the elongated hole HS2a of the pin receiving portion HS2 of the lateral sliding member HS of the sliding part SP, and is fixed inside the lid body 120. The connecting part CP is then rotatable about the lever pin Pn2. As described above, the lever pin Pn2 allows the lateral sliding member HS of the sliding part SP to slide in the front-to-rear direction along the elongated hole HS2a.

[0038] (5-4) Rear coil spring The rear coil spring Sf1 biases the vertical slide member VS of the slide portion SP diagonally upward (upward and forward). As described above, one end of the rear coil spring Sf1 is fitted into the spring mounting portion VS5 of the vertical slide member VS of the slide portion SP, and the other end of the rear coil spring Sf1 is fitted into the spring mounting portion HS6 of the horizontal slide member HS of the slide portion SP. At this time, the rear coil spring Sf1 is located between the pair of left and right front wall portions HS4 of the horizontal slide member HS of the slide portion SP (see FIG. 4).

[0039] (5-5) Locking mechanism The locking mechanism LM is mainly composed of an opening / closing lever part OP, a pivot pin Pn3, and a front coil spring Sf2, as shown in Figures 4, 7, and 8. Each of these components will be described in detail below.

[0040] (5-5-1) Opening and closing lever parts The opening / closing lever part OP is rotatable around the pivot pin Pn3, and as shown in FIGS. 4, 7, and 8, is mainly formed of a pressed part OP1, a spring installation part OP2, a first extension wall part OP3, a second extension wall part OP4, and a claw part OP5. As shown in FIGS. 4, 7, and 8, the pressed part OP1 is a plate-shaped member and can come into contact with the pressing part CP1 of the connecting part CP. As shown in FIGS. 4 and 8, the spring installation part OP2 extends downward from the lower surface of the pressed part OP1. One end of the front coil spring Sf2 is fitted into this spring installation part OP2 (see FIGS. 4 and 8). As shown in FIGS. 4, 7, and 8, the first extension wall part OP3 extends forward from the front end of the pressed part OP1. As shown in FIGS. 4, 7, and 8, the second extending wall portion OP4 extends downward from the front end of the first extending wall portion OP3 and is disposed between the pair of left and right front pin receiving portions 121F of the lid main body 121. As shown in FIG. 8, a through hole OP4a through which the pivot pin Pn3 is inserted is formed in the vertically intermediate portion and left and right portions of the second extending wall portion OP4. As shown in FIGS. 4 and 8, the claw portion OP5 extends rearward from the lower end of the second extending wall portion OP4. As described above, the claw portion OP5 can be engaged with the front claw receiving portion 112 of the plug main body 110.

[0041] (5-5-2) Rotating shaft pin As described above, the pivot pin Pn3 is inserted through the through-hole 121f of the front pin receiving portion 121F of the lid main body 121 and the through-hole OP4a of the second extending wall portion OP4 of the opening / closing lever part OP, and is fixed inside the lid body 120. Then, the opening / closing lever part OP becomes rotatable about the pivot pin Pn3.

[0042] (5-5-3) Front coil spring As described above, one end of the front coil spring Sf2 is disposed inside the spring mounting portion 121G of the lid main body 121, and the other end of the front coil spring Sf2 is fitted into the spring mounting portion OP2 of the opening-closing lever part OP. As shown in Fig. 4, the front coil spring Sf2 urges the pressed portion OP1 of the opening-closing lever part OP upward, urges the portion of the second extending wall portion OP4 of the opening-closing lever part OP that is located above the through-hole OP4a forward, and urges the portion of the second extending wall portion OP4 of the opening-closing lever part OP that is located below the through-hole OP4a and the claw portion OP5 of the opening-closing lever part OP backward. As described above, the front coil spring Sf2 indirectly biases the pressing portion CP1 of the connecting portion CP upward via the opening / closing lever part OP, and indirectly biases the pressing portion HS1 of the lateral slide member HS of the slide portion SP backward via the opening / closing lever part OP and the connecting portion CP (i.e., indirectly biases the slide portion SP backward).

[0043] (6) Hinge mechanism The hinge mechanism 140 is made up of the cover portion-side connecting portion CV5 of the plug body cover member CV, the lid body-side connecting portion 121D of the lid body 121, the pin receiving portion 122E of the lid body cover member 122, and the hinge pin Pn1. As shown in Figures 1 to 4, when the lid body-side connecting portion 121D of the lid body 121 is sandwiched between the cover portion-side connecting portion CV5 of the plug body cover member CV and the pin receiving portion 122E of the lid body cover member 122, and the through hole 122e of the pin receiving portion 122E of the lid body cover member 122, the through hole 121d of the lid body-side connecting portion 121D of the lid body 121, and the through hole CV5a of the cover portion-side connecting portion CV5 of the plug body cover member CV communicate with each other to form a single communication hole, the hinge pin Pn1 is inserted into this communication hole, thereby completing the hinge mechanism 140. As described above, when the claw portion OP5 of the opening / closing lever part OP of the locking mechanism LM is released from its engagement with the front claw receiving portion 112 of the plug body 110, the repulsive force of the packing 123 when the compressed state of the packing 123 is released urges the lid body 120 in the opening direction, causing it to rotate in the opening direction around the hinge pin Pn1.

[0044] <Method of use and operation of beverage container according to an embodiment of the present invention> The following describes how to use the beverage container 1 according to an embodiment of the present invention, as well as its operation. First, a user of this beverage container 1 pours a desired beverage into the vacuum double container 10. Next, as shown in FIG. 4 , the user engages the claw portion OP5 of the opening / closing lever part OP with the front claw receiving portion 112 of the plug body 110 to close the lid body 120 of the plug body 100 and lock the slide portion SP of the plug body 100. At this time, the packing 123 is compressed, blocking the lower opening 111a of the drinking spout portion 111 of the plug body 110 and maintaining a watertight seal between the plug body 110 and the lid body 120. Next, the user attaches the plug body 100 to the vacuum double container 10 by threading the male thread portion 12B of the outer tube 12 of the vacuum double container 10 with the female thread portion CV3 of the plug body cover member CV of the plug body 100, thereby completing the beverage container 1. At this time, the annular packing PK abuts against the upper end of the inner cylinder side wall 11A of the inner cylinder 11 of the vacuum double vessel 10, as shown in FIG. 4, to keep the vacuum double vessel 10 and the plug 100 watertight.

[0045] As shown in FIG. 4, when the claw portion OP5 of the opening / closing lever part OP is engaged with the front claw receiving portion 112 of the plug body 110 and the lid body 120 is in the closed state, the front coil spring Sf2 urges the pressed portion OP1 of the opening / closing lever part OP upward, urging the portion of the second extending wall portion OP4 of the opening / closing lever part OP located below the through-hole OP4a and the claw portion OP5 of the opening / closing lever part OP rearward. Also, as shown in FIG. 4, the front coil spring Sf2 indirectly urges the pressing portion CP1 of the connecting part CP upward, thereby indirectly urging the sliding portion SP rearward. Therefore, the sliding portion SP is in the rear position. As shown in FIG. 4, when the sliding portion SP is in the locked state, the vertical sliding member VS of the sliding portion SP is in the upper position, and the upper end of the base portion VS1 of the vertical sliding member VS of the sliding portion SP is closely opposed to the blocking portion 122b of the side wall portion 122B of the lid body cover member 122. Therefore, when the slide part SP is in the locked state, the user cannot move the slide part SP from the rear position to the front position, and cannot operate the opening / closing lever part OP via the connecting part CP. Therefore, the engagement between the claw part OP5 of the opening / closing lever part OP and the front claw receiver 112 of the plug body 110 is not released, and the lid body 120 does not enter the open state.

[0046] When a user opens the lid body 120 to drink the beverage in the beverage container 1, the user must first unlock the sliding portion SP. To do this, as shown in FIG. 11 , the user places their finger on the finger receiving portion VS2 of the vertical sliding member VS of the sliding portion SP and pushes down the vertical sliding member VS of the sliding portion SP against the biasing force of the rear coil spring Sf1, sliding the vertical sliding member VS of the sliding portion SP from the upper position to the lower position. As a result, as shown in FIG. 11 , the upper end of the base portion VS1 of the vertical sliding member VS of the sliding portion SP and the blocking portion 122b of the side wall portion 122B of the lid body cover member 122 are not in close proximity to each other. Then, as shown in FIG. 12 , when the user presses the vertical sliding member VS of the sliding portion SP forward while placing their finger on the finger receiving portion VS2 of the vertical sliding member VS of the sliding portion SP, the horizontal sliding member HS of the sliding portion SP is pressed forward via the vertical sliding member VS of the sliding portion SP and slides forward. In other words, the slide portion SP moves from the rear position to the front position. At this time, as shown in FIG. 12, the pin receiving portion CP2 of the connecting part CP is pressed forward by the pressing portion HS1 of the lateral slide member HS of the slide portion SP, and the connecting part CP rotates forward about the lever pin Pn2 against the biasing force of the front coil spring Sf2. The pressing portion CP1 of the connecting part CP presses the pressed portion OP1 of the opening / closing lever part OP downward, causing the opening / closing lever part OP to rotate about the pivot pin Pn3, and the claw portion OP5 of the opening / closing lever part OP disengages from the front claw receiving portion 112 of the plug body 110. When the lid 120 can be opened in this way, the compressed state of the packing 123 is released. The lid 120 is then biased in the open direction by the repulsive force (biasing force) of the packing 123 and rotates in the open direction around the hinge pin Pn1, reaching an open state in which the claw portion OP5 of the opening / closing lever part OP is positioned above the front claw receiving portion 112 of the plug body 110 (see FIG. 13). The user then removes their finger from the finger receiving portion VS2 of the vertical sliding member VS of the sliding portion SP. At this time, as shown in FIG. 13, the sliding portion SP is again locked by the biasing force of the front coil spring Sf2 and the biasing force of the rear coil spring Sf1.The user then inserts their fingers into the gap between the lid 120 and the plug body cover member CV and fully opens the lid 120. Then, while holding the lid 120 in the fully open position with their fingers, the user lifts the beverage container 1 with their hand and brings the drinking spout 111 of the plug body 110 to their mouth to drink the beverage in the beverage container 1.

[0047] After finishing the beverage, the user pushes the lid 120 downward with their finger to close the lid again. At this time, the claw portion OP5 of the opening / closing lever part OP is pushed downward while abutting against the front claw receiving portion 112 of the plug body 110, and the opening / closing lever part OP rotates slightly around the pivot pin Pn3 against the biasing force of the front coil spring Sf2. When the claw portion OP5 of the opening / closing lever part OP is positioned below the front claw receiving portion 112 of the plug body 110, the claw portion OP5 of the opening / closing lever part OP is biased rearward by the biasing force of the front coil spring Sf2. As a result, the claw portion OP5 of the opening / closing lever part OP is engaged with the front claw receiving portion 112 of the plug body 110, and the lid 120 is again closed while the slide part SP remains locked. Furthermore, when a user is carrying a beverage container 1 in which the claw portion OP5 of the opening / closing lever part OP is engaged with the front claw receiving portion 112 of the stopper body 110, the lid body 120 is in the closed state, and the slide portion SP of the stopper body 100 is in the locked state, by holding the handle 122D of the lid body cover member 122 with one hand, the user can use only that hand (without using the other hand) to release the locked state of the slide portion SP and set the lid body 120 to the open state, and then set the lid body 120 to the closed state again.

[0048] <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, the slide portion SP of the operating mechanism 124 is fitted into an opening formed at the rear end of the side wall portion 122B of the lid body cover member 122, and is provided on the lid body 120 so as to be positioned inside the handle 122D of the lid body cover member 122. Therefore, in this beverage container 1, the lid body 120 can be opened while holding the handle 122D of the lid body cover member 122 with one hand without changing the hand holding it.

[0049] (2) In the beverage container 1 according to the embodiment of the present invention, the operating mechanism 124 is disposed within the lid 120, and the connecting part CP of the operating mechanism 124 is connected to the locking mechanism LM of the operating mechanism 124 and the sliding part SP of the operating mechanism 124. Furthermore, the sliding part SP of the operating mechanism 124 can operate the locking mechanism LM of the operating mechanism 124 via the connecting part CP of the operating mechanism 124. Therefore, in this beverage container 1, the degree of freedom in designing the locking mechanism LM of the operating mechanism 124, the sliding part SP of the operating mechanism 124, and the lid 120 can be maximized.

[0050] (3) In the beverage container 1 according to the embodiment of the present invention, the sliding portion SP of the operating mechanism 124 can be switched between a locked state and an unlocked state. Therefore, in this beverage container 1, the user can switch the sliding portion SP of the operating mechanism 124 to the locked state except when attempting to open the lid body 120. Therefore, in this beverage container 1, it is possible to prevent as much as possible the lid body 120 from being accidentally opened due to a finger or the like accidentally coming into contact with the sliding portion SP of the operating mechanism 124.

[0051] (4) In the beverage container 1 according to the embodiment of the present invention, when the lid body 120 changes from the closed state to the open state, the biasing force of the front coil spring Sf2 of the operating mechanism 124 and the biasing force of the rear coil spring Sf1 of the operating mechanism 124 change the sliding portion SP of the operating mechanism 124 from the unlocked state to the locked state. When the lid body 120 changes from the open state to the closed state, the sliding portion SP of the operating mechanism 124 remains in the locked state. Therefore, in this beverage container 1, it is possible to prevent forgetting to switch the sliding portion SP of the operating mechanism 124 from the unlocked state to the locked state after the lid body 120 has changed to the closed state.

[0052] (5) In the beverage container 1 according to the embodiment of the present invention, when the lid 120 is in the closed state, the packing 123 is in a compressed state and blocks the lower opening 111a of the spout 111 of the plug body 110. When the claw portion OP5 of the opening / closing lever part OP of the locking mechanism LM of the operating mechanism 124 disengages from the front claw receiving part 112 of the plug body 110, the lid 120 is biased in the opening direction by the biasing force of the packing 123. Therefore, in this beverage container 1, the lid 120 can be automatically opened when the claw portion OP5 of the opening / closing lever part OP of the locking mechanism LM of the operating mechanism 124 disengages from the front claw receiving part 112 of the plug body 110.

[0053] <Modification> (A) In the beverage container 1 according to the previous embodiment, the connecting part CP of the operating mechanism 124 was arranged inside the lid body 120. However, the connecting part CP of the operating mechanism 124 does not have to be arranged inside the lid body 120, and may be arranged, for example, outside the lid body 120. Also, in the beverage container 1 according to the previous embodiment, the sliding part SP of the operating mechanism 124 was able to operate the locking mechanism LM of the operating mechanism 124 via the connecting part CP of the operating mechanism 124. However, the connecting part CP of the operating mechanism 124 may be removed so that the sliding part SP of the operating mechanism 124 can directly operate the locking mechanism LM of the operating mechanism 124.

[0054] (B) In the beverage container 1 according to the previous embodiment, the sliding portion SP of the operating mechanism 124 can be switched between a locked state and an unlocked state by the vertical sliding member VS of the sliding portion SP of the operating mechanism 124. However, the vertical sliding member VS of the sliding portion SP of the operating mechanism 124 may be removed so that the sliding portion SP of the operating mechanism 124 is always in the unlocked state. In other words, the sliding portion SP of the operating mechanism 124 may always be movable from the rear position to the front position.

[0055] (C) In the beverage container 1 according to the previous embodiment, when the lid body 120 changes from the closed state to the open state, the sliding portion SP of the operating mechanism 124 changes from the unlocked state to the locked state due to the biasing force of the front coil spring Sf2 and the biasing force of the rear coil spring Sf1 of the operating mechanism 124. Then, when the lid body 120 changes from the open state to the closed state, the sliding portion SP of the operating mechanism 124 remains locked. However, even when the lid body 120 changes from the closed state to the open state, the sliding portion SP of the operating mechanism 124 does not necessarily change from the unlocked state to the locked state. Then, after the lid body 120 changes from the open state to the closed state, the vertical sliding member VS of the sliding portion SP of the operating mechanism 124 may be moved from the lower position to the upper position by the user, and the sliding portion SP of the operating mechanism 124 may change from the unlocked state to the locked state.

[0056] (D) In the beverage container 1 according to the previous embodiment, when the claw portion OP5 of the opening / closing lever part OP of the locking mechanism LM of the operating mechanism 124 is locked in the front claw receiving part 112 of the plug body 110, the packing 123 is compressed and blocks the lower opening 111a of the spout 111 of the plug body 110. When the claw portion OP5 of the opening / closing lever part OP of the locking mechanism LM of the operating mechanism 124 is disengaged from the front claw receiving part 112 of the plug body 110, the lid body 120 is biased in the opening direction by the biasing force of the packing 123. However, when the claw portion OP5 of the opening / closing lever part OP of the locking mechanism LM of the operating mechanism 124 is locked in the front claw receiving part 112 of the plug body 110, the packing 123 may block the lower opening 111a of the spout 111 of the plug body 110 without being compressed. Even if the claw portion OP5 of the opening / closing lever part OP of the locking mechanism LM of the operating mechanism 124 comes off the front claw receiving portion 112 of the plug body 110, the packing 123 does not need to bias the lid body 120 in the opening direction.

[0057] (E) Although not mentioned in the beverage container 1 of the previous embodiment, the hinge mechanism 140 may be provided with a torque hinge spring that urges the lid body 120 in the opening direction, and when the claw portion OP5 of the opening / closing lever part OP of the locking mechanism LM of the operating mechanism 124 disengages from the front claw receiving portion 112 of the stopper body 110, the lid body 120 may be brought into an open state (e.g., a fully open state) by the torque hinge spring.

[0058] (F) In the beverage container 1 according to the previous embodiment, the sliding member SP of the operating mechanism 124 is locked when the vertical sliding member VS of the sliding member SP of the operating mechanism 124 is in the upper position, and is unlocked when the vertical sliding member VS of the sliding member SP of the operating mechanism 124 is in the lower position. However, the sliding member SP of the operating mechanism 124 may be locked when the vertical sliding member VS of the sliding member SP of the operating mechanism 124 is in a position other than the upper position (e.g., the lower position), and may be unlocked when the vertical sliding member VS of the sliding member SP of the operating mechanism 124 is in a position other than the lower position (e.g., the upper position). In such a case, it is preferable that a blocking portion be formed on the lid body cover member 122 or the like, which can come into close contact with the vertical sliding member VS of the sliding member SP of the operating mechanism 124 when the vertical sliding member VS of the sliding member SP of the operating mechanism 124 is in a position other than the upper position (e.g., the lower position).
