DETAILED DESCRIPTION OF THE INVENTION

[0008] Beverage containers according to embodiments will be described in detail below with reference to the drawings.

[0009] In order to facilitate understanding of the invention, the position, size, shape, range, etc. of each component shown in the following drawings may not represent the actual position, size, shape, range, etc. Therefore, the present invention is not necessarily limited to the position, size, shape, range, etc. disclosed in the drawings, etc. In the embodiments, elements expressed in the singular include the plural unless otherwise clearly indicated in the context. First Embodiment

[0010] Fig. 1 is a perspective view showing a beverage container according to a first embodiment, Fig. 2 is an exploded perspective view showing a beverage container according to the first embodiment, and Fig. 3 is a perspective view illustrating a container body according to the first embodiment. The beverage container 1 of the embodiment is pot-shaped and has a container body 2 and a lid 3.

[0011] The container body 2 has, for example, a vacuum double-wall structure, and includes a storage section 20 in which a beverage is stored, and an annular opening 21 through which the beverage can flow into and out of the storage section 20, as shown in FIG. 3. The beverage is not particularly limited, but examples thereof include water, tea, and coffee. As shown in FIG. 3, a lid placement section 22 is located below the opening 21, in which a part of the lid section 3 (including the lock switch 321 shown in FIG. 2) is located. A threaded portion 23 that threadably engages with the threaded portion of the lid section 3 is provided below the lid placement section 22. As shown in FIG. 3, the lid placement section 22 is located closer to the opening 21 than the threaded portion 23. The container body 2 is also provided with a handle 24 and a flow path 25. The flow path 25 is a flow path for the beverage flowing out from the reservoir 20.

[0012] The lid part 3 is attached to the container body 2 so as to cover the opening 21. The lid part 3 is attached to the container body 2 so as to cover the opening 21, and is provided with a flow path for discharging the beverage from the storage part 20. 1 to 3 that have not yet been explained will be explained later. Fig. 4 is an exploded perspective view of the beverage container according to the embodiment, and Figs. 5 and 6 are exploded views of the lid of the embodiment.

[0013] The lid part 3 has an upper lid 31, a lower lid 32, and a flow path opening and closing mechanism 33. A part of the structure of the lower lid 32 and the flow path opening and closing mechanism 33 form an opening and closing mechanism that opens and closes the flow path when discharging the beverage from the storage part 20.

[0014] As shown in Figure 5, top cover 31 has top portion 311 and side portion 312 that cover the opening of bottom cover 32. Top cover 31 also has lever 313 and protrusion 314. Protrusion 314 is an example of a fitting portion. Lever 313 has shaft pressing portion 313a. When a user presses lever 313 downward with, for example, their thumb, shaft pressing portion 313a can press the tip portion of shaft 334. The protrusion 314 is provided at a position corresponding to the lock switch 321, and is a plate-like member that protrudes inward from the side of the top cover 31. As shown in FIG. 6, the lower cover 32 is provided with a pair of lock switches 321, 321, a screw-fitting portion 322, a lever arrangement portion 323, and a flow path 324, spaced 180 degrees apart.

[0015] The lock switches 321, 321 are part of a lock mechanism for fastening the upper cover 31 to the lower cover 32. The lock mechanism using the lock switches 321, 321 will be described in detail later. The protrusion 314 and the lock switch 321 form the main part of the support that supports the upper cover 31 so that it does not separate from the lower cover 32. The threaded portion 322 is threadably engaged with the threaded portion 23 .

[0016] The lever arrangement portion 323 has a shape corresponding to the lever 313. The lever 313 is arranged in the lever arrangement portion 323 when the upper cover 31 is fixed to the lower cover 32. The flow path 324 is a flow path for the beverage to flow out of the reservoir 20. 4 prevents the beverage in the container body 2 from entering anywhere other than the flow path 324. Note that the illustration of the packing 325 is omitted in FIG.

[0017] The flow path opening and closing mechanism 33 includes lock rings 331 and 332 , a spring 333 , a shaft 334 , a packing 335 , a spring 336 , a base 337 , and a packing 338 . Lock rings 331 and 332, a spring 333, a packing 335, a spring 336, a base 337, and a packing 338 are attached to a shaft 334.

[0018] Lock ring 331 engages with engaging portion 334a provided on shaft 334. This lock ring 331 serves to fasten spring 333 to shaft 334. Lock ring 331 can be disengaged from engaging portion 334a by rotating, and can be removed from shaft 334. Lock ring 331 is movable in the axial direction of shaft 334, but when it abuts against protrusion 334b ​​located midway along shaft 334, further movement toward lock ring 331 is restricted. The packing 335 prevents the beverage in the container body 2 from entering anywhere other than the flow path 324 of the lower lid 32.

[0019] The spring 336 is sandwiched between the lock ring 332 and the base 337 and in a contracted state biases the lock ring 332, causing the lock ring 332 to abut against the convex portion 334b ​​arranged midway along the shaft 334 described above.

[0020] The base 337 has a circular shape that rises slightly toward the center. An opening (described later) through which the shaft 334 of the base 337 passes is provided in the center of the base 337. The base 337 abuts against the packing 325 due to the bias of the spring 333. By moving the base 337 downward in the plane of the drawing, the beverage in the container body 2 can be made to flow into the flow path 324. The packing 338 closes the opening of the base 337 through which the shaft 334 passes. FIG. 7 is a diagram illustrating the arrangement of the lower cover and the flow channel opening and closing mechanism. As shown in FIG. 7, the lower cover 32 is provided with a shaft receiving portion 326 .

[0021] The shaft receiving portion 326 has a long, thin cylindrical shape with both ends 326a and 326b open. The shaft 334 is disposed inside the shaft receiving portion 326. Further, a recess 327 corresponding to the shape of the lock ring 332 (to accommodate the lock ring 332) is provided near the end 326b.

[0022] One end 333a of the spring 333 abuts against the lock ring 331, and the other end 333b abuts against the base 326c of the shaft receiving portion 326. The spring 333 is held in a contracted state between the lock ring 331 and the base 326c, urging the shaft 334 upward in the drawing.

[0023] The base 337 also has a recess 337a that corresponds to the shape of the packing 338. When the flow path opening / closing mechanism 33 is attached to the lower cover 32, most of the packing 338 is housed in the recess 337a in a side view. Next, the locking mechanism by the lock switch 321 will be described with reference to FIGS. 8 and 9 are side cross-sectional views illustrating a locking mechanism using a lock switch. Each lock switch 321 has a hook portion 321a, a recessed portion 321b, a pressing portion 321c, and a bearing portion 321d. The hook portion 321a is an example of a fitting portion.

[0024] The hook portion 321a is supported by a shaft of the bearing portion 321d, and can rotate clockwise and counterclockwise on the page around the bearing portion 321d.

[0025] The hook portion 321a is biased by a spring 321e toward the outside of the lower cover 32. Specifically, the hook portion 321a on the left side in Fig. 7 is biased toward the left side of the paper by the spring 321e, and the hook portion 321a on the right side in Fig. 7 is biased toward the right side of the paper by the spring 321e.

[0026] As shown in FIGS. 7 to 9, when the user grasps the edge of top cover 31 and brings it close to bottom cover 32, hook 321a comes into contact with protrusion 314. When the user applies further downward pressure to top cover 31 against the bias of spring 321e, hook 321a moves toward the inside of bottom cover 32 (for example, hook 321a on the left in FIG. 7 moves toward the right side of the drawing), and protrusion 314 climbs over the tip of hook 321a. When protrusion 314 climbs over the tip of hook 321a, hook 321a moves toward the outside of bottom cover 32 due to the bias of spring 321e, and protrusion 314 is positioned within recess 321b and is fixed by being fitted with hook 321a. In addition, shaft pressing portion 313a abuts the tip of shaft 334. In addition, the contact surfaces of the hook 321a and the protrusion 314 each have an oblique slope when viewed from the side so that the hook 321a can easily move to the inside of the lower cover 32 when the protrusion 314 presses the hook 321a. FIG. 10 is a side cross-sectional view illustrating the lock release mechanism.

[0027] When removing the top lid 31 from the bottom lid 32, the user grasps either one of the pressing portions 321c (the right pressing portion 321c in FIG. 10) and applies a force that contracts the spring 321e, thereby releasing the engagement between the right hook portion 321a and the convex portion 314 in FIG. 10. In this state, when the top lid 31 is lifted upward while rotating counterclockwise around the engagement portion between the left hook portion 321a and the convex portion 314 in FIG. 10, the convex portion 314 can be separated from the right hook portion 321a.

[0028] When one of the lock switches 321, 321 located at both ends is released from the engaged state and rotated around the other engagement portion as the center of rotation, the protrusion 314 can be easily separated from the left hook portion 321a by moving the top cover 31, for example, in the direction of the arrow in Figure 10, without pressing the pressing portion 321c for the other engagement portion (the portion circled in Figure 10). Next, an example of how to use the beverage container 1 of the first embodiment will be described with reference to FIGS.

[0029] The user attaches the flow path opening / closing mechanism 33 to the lower cover 32. Specifically, the user inserts the shaft 334, to which the lock ring 332, packing 335, spring 336, base 337, and packing 338 are attached, from the end 326b side of the shaft receiving portion 326 toward the end 326a side. Then, the user places the spring 333 so as to surround the shaft receiving portion 326, presses the upper end of the spring 333 with the lock ring 331, and rotates the lock ring 331 to engage with the engaging portion 334a provided on the shaft 334. This fixes the flow path opening / closing mechanism 33 to the lower cover 32, and the base 337 abuts against the packing 325.

[0030] Next, the user grasps the edge of the upper lid 31 and brings it close to the lower lid 32, and engages the two with the lock switch 321. As a result, the upper lid 31 is supported by the lower lid 32.

[0031] Then, the user grips the lid portion 3 and rotates the lid portion 3 clockwise in the lid placement portion 22 to screw the threaded portion 322 into the threaded portion 23. This fixes the lid portion 3 to the container body 2. 11 and 12 are diagrams illustrating the beverage container when the threaded portion is threadedly engaged with the mating portion.

[0032] 11, when the threaded portion 322 is threaded into the threaded portion 23, the lock switch 321 is disposed inside the lid placement portion 22 and is not visible from the outside, and the user cannot operate the lock switch 321. This makes it possible to prevent the upper lid 31 from coming off the lower lid 32 due to some kind of malfunction. 13 and 14 are diagrams illustrating an example of how the beverage container according to the first embodiment is used.

[0033] When a user presses down on lever 313, shaft pressing portion 313a comes into contact with the tip of shaft 334, causing shaft 334 to move downward against the bias of spring 333. As a result, base 337 also moves downward, and as shown in FIG. 14, a gap s (area surrounded by a dotted circle) through which beverage can pass is formed between packing 325 and upper surface 337a of base 337. When lever 313 is pressed down, lever 313 comes into contact with bottom portion 323a of lever placement portion 323. This causes shaft 334 to stop at the position where it has moved downward. In this state, if beverage container 1 is tilted to a certain extent, beverage will pass through gap s. The beverage that passes through gap s is released to the outside through flow path 324 and flow path 25.

[0034] 13, when the pressure inside storage section 20 is higher than atmospheric pressure due to temperature differences or the like, shaft pressing section 313a comes into contact with the tip of shaft 334 and shaft 334 starts to move downward, shaft 334 moves downward before base 337 (before base 337 starts to move). This is because the surface area of ​​packing 338 is smaller than the surface area of ​​the underside of base 337, and therefore the force it receives from the pressure inside container body 2 is smaller than that received by base 337.

[0035] When shaft 334 moves downward before base 337, a gap is formed between packing 338 and the opening of base 337 through which shaft 334 passes, allowing the pressure inside reservoir 20 to pass. The pressure inside reservoir 20 escapes through this gap (pressure relief mechanism). This allows the user to move base 337 downward with less force than if there was no pressure relief mechanism. When the pressure inside reservoir 20 returns to atmospheric pressure and base 337 moves downward, packing 338 closes the opening of base 337 through which shaft 334 passes.

[0036] When the user releases lever 313, base 337 is urged upward by spring 333 and comes into contact with packing 325. This results in the state shown in Figure 12, and the inside of reservoir 20 is again kept airtight. The beverage container 1 according to the embodiment includes a mechanism for preventing the lock switch 321 from malfunctioning. Next, a mechanism for preventing the lock switch 321 from malfunctioning will be described. FIG. 15 is a diagram illustrating a mechanism for suppressing malfunction of the lock switch according to the first embodiment.

[0037] When a force is applied to separate the top lid 31 from the bottom lid 32 without using the lock switch 321 (for example, when the top lid 31 is forcibly pulled upward from the state shown in FIG. 11 without releasing the engagement between the threaded portion 322 and the threaded portion 23), the protrusion 314 presses the hook portion 321a in a direction that contracts the spring 321e, causing the hook portion 321a to move slightly inward. At this time, the end portion 321f opposite the hook portion 321a across the bearing portion 321d of the lock switch 321 abuts against the side portion of the lid placement portion 22, restricting the movement of the hook portion 321a, i.e., preventing the hook portion 321a from climbing over the tip of the protrusion 314. Therefore, the engagement between the hook portion 321a and the protrusion 314 is not released, and the top lid 31 can be prevented from separating from the bottom lid 32.

[0038] As described above, the beverage container 1 of the first embodiment includes a container body 2 including a storage section 20 for storing a beverage therein and an opening 21 through which the beverage enters and exits; and a lid section 3 attached to the container body 2 to cover the opening 21 and opening and closing a flow path when discharging the beverage from the storage section 20. The lid section 3 includes a lower lid 32 having an opening, a flow path opening / closing mechanism 33 attached to the lower lid 32 and opening and closing the flow path by a predetermined operation, an upper lid 31 covering the opening of the lower lid 32, and a lock switch 321 supporting the upper lid 31 so as not to separate from the lower lid 32. When the lid section 3 is attached to the container body 2 with the upper lid 31 engaged with the lower lid 32, the lock switch 321 is hidden by the container body 2 and the upper lid 31. This prevents the lid from coming off due to an accidental operation. Therefore, a separate locking mechanism or the like for preventing the lock switch 321 from being released is not required. Furthermore, when the lid portion 3 is not attached to the container body 2, the user can easily separate the upper lid 31 from the lower lid 32 using the lock switch 321.

[0039] In addition, the structure of the container body 2 has been devised to place the lid placement section 22 right next to the lock switch 321, thereby restricting the movement of the lock switch 321 and providing a mechanism to suppress malfunction of the lock switch 321, thereby preventing malfunctions unintended by the user.

[0040] In this embodiment, the lock switch 321 is disposed on the lower cover 32 side, but this is not limiting and the lock switch may be disposed on the upper cover 31 side. That is, the hook portion may be disposed on the upper cover 31 side and the hook receiving portion may be disposed on the lower cover 32 side. Furthermore, the hook portion 321a and the protrusion 314 are examples of a fitting portion and a fitted portion, and the shapes of the fitting portion and the fitted portion are not limited to those shown in the drawings. Furthermore, the method of fixing the upper cover 31 and the lower cover 32 is not limited to fitting. For example, press fitting may be used. Furthermore, the mechanism for fixing the lid portion 3 to the beverage container 2 is not limited to a screw-type mechanism, and a conventionally known mechanism may also be used.

[0041] In this embodiment, a pair of combinations of the lock switch 321 and the protrusion 314 are provided, but the present invention is not limited to this and there may be only one combination of the lock switch 321 and the protrusion 314. <Second embodiment> Next, a beverage container according to a second embodiment will be described.

[0042] Below, the second embodiment of the beverage container will be described, focusing on the differences from the first embodiment described above, and similar items (parts that have the same functions as the first embodiment even if their shapes are slightly different) will be given the same symbols as the first embodiment and detailed descriptions will be omitted. FIG. 16 is a perspective view showing a beverage container according to the second embodiment. A beverage container 1a according to the second embodiment shown in FIG. 16 differs from the beverage container according to the first embodiment in the configuration and arrangement position of the lock switch. The beverage container 1 a of the second embodiment has a container body 2 and a lid portion 4 . FIG. 17 is a perspective view illustrating a cover according to the second embodiment. The lid portion 4 has an upper lid 41, a lower lid 42, and a flow path opening and closing mechanism 33.

[0043] The upper cover 41 is provided with a lever 411 and hooks 412a and 412b that are inserted into holes 421a and 421b formed in the lower cover 42. The hooks 412a and 412b are an example of a first fitting portion. The holes 421a and 421b are an example of a first fitted portion.

[0044] The lower cover 42 is provided with a screw portion 322, a flow path 324, and a packing 325. The holes 421a and 421b are arranged in positions that do not interfere with the flow path 324 (slightly diagonally above the flow path 324 in this embodiment). FIG. 18 is a perspective view illustrating the top cover of the second embodiment.

[0045] A shaft pressing portion 411a is provided on the lever 411. When the user presses the lever 411 downward with, for example, the thumb, the shaft pressing portion 411a can press the tip portion of the shaft 334.

[0046] Furthermore, the top cover 41 is provided with a push switch 413 and a housing portion 414. The push switch 413 has hook portions 413a and 413b and a pressing portion 413c. The hook portions 413a and 413b are an example of a second fitting portion. In this embodiment, the hook portions 413a and 413b and the pressing portion 413c are formed from a single member. The push switch 413 is biased by a spring (described later) in a direction that pushes the pressing portion 413c out of the housing portion 414. When the pressing portion 413c is pressed, the hook portions 413a and 413b move into the housing portion 414 as the pressing portion 413c moves. When the pressing portion 413c is released, the hook portions 413a and 413b jump out of the housing portion 414 to the position shown in FIG. 18 as the pressing portion 413c moves.

[0047] As shown in FIG. 18, the hooks 412a, 412b and the hooks 413a, 413b are provided at positions spaced apart by approximately 180 degrees in plan view (when the beverage container 1a is viewed from above). FIG. 19 is a perspective view illustrating the lower cover of the second embodiment. The lower cover 42 is provided with a push switch placement portion (cutout portion) 422 corresponding to the push switch 413.

[0048] In addition, hook receiving portions 423a and 423b are provided on the lower cover 42 at positions corresponding to the hook portions 413a and 413b. The hook receiving portions 423a and 423b are an example of second fitted portions. The hook receiving portions 423a and 423b have recesses that accommodate the hook portions 413a and 413b. FIG. 20 is a plan view showing the cover of the second embodiment, and FIG. 21 is a cross-sectional view taken along line AA in FIG.

[0049] When upper lid 41 is fitted onto lower lid 42, hooks 412a and 412b are positioned within holes 421a and 421b, respectively. Hooks 413a and 413b are positioned in recesses provided in hook receivers 423a and 423b, respectively. As described above, push switch 413 is biased by spring 415 in a direction that pushes pressing portion 413c out of housing portion 414. Next, an example of how to use the beverage container 1 of the second embodiment will be described. The user attaches the flow path opening and closing mechanism 33 to the lower cover 42 . FIG. 22 is a diagram illustrating a method for attaching the top cover according to the second embodiment.

[0050] The user grasps top cover 41 and inserts hooks 412a and 412b into holes 421a and 421b. Then, the user brings hooks 413a and 413b close to hook receivers 423a and 423b as shown in Fig. 22. When the inclined surfaces of hooks 413a and 413b come into contact with the inclined surfaces of hook receivers 423a and 423b, a force is applied to hooks 413a and 413b to move them to the left side of the page, and spring 415 that biases push switch 413 contracts.

[0051] When the user further increases the force with which hook portions 413a and 413b are pressed against hook receiving portions 423a and 423b, spring 415 further contracts, causing hook portions 413a and 413b to climb over the slopes of hook receiving portions 423a and 423b, and hook portions 413a and 413b to be positioned in the recesses provided in hook receiving portions 423a and 423b. When hook portions 413a and 413b climb over the slopes of hook receiving portions 423a and 423b, the user may press pressing portion 413c to assist the climbing over. In addition, the contact surfaces of hook portions 413a, 413b and hook receiving portions 423a, 423b have an oblique slope shape in side view so that spring 415 can easily contract when hook portions 413a, 413b press hook receiving portions 423a, 423b.

[0052] Then, the user grips the lid portion 4 and rotates it clockwise within the lid placement portion 22 to screw the threaded portion 322 into the threaded portion 23. This fixes the lid portion 4 to the container body 2. FIG. 23 is a plan view showing a beverage container according to the second embodiment, and FIG. 24 is a cross-sectional view taken along line BB in FIG.

[0053] In the beverage container 1a of the second embodiment, when the threaded portion 322 is threaded into the threaded portion 23, the push switch 413 is disposed inside the lid placement portion 22, and is not visible from the outside, and the user cannot operate the push switch 413 (pressing portion 413c). This makes it possible to prevent the upper lid 41 from coming off the lower lid 42 due to some kind of malfunction.

[0054] When removing the lid portion 4 from the container body 2, the user grips the lid portion 4 and rotates the lid portion 4 counterclockwise to release the engagement between the threaded portion 322 and the threaded portion 23.

[0055] When removing the top lid 41 from the bottom lid 42, the user presses the pressing portion 413c and lifts the top lid 41 around the portion where the hook portions 412a, 412b are fitted into the holes 421a, 421b as the axis of rotation. This allows the hook portions 413a, 413b to be released from the engagement with the hook receiving portions 423a, 423b (the state shown in FIG. 22).

[0056] The beverage container 1a of the second embodiment can achieve the same effects as the beverage container 1 of the first embodiment. Furthermore, with this beverage container 1a, by operating the pressing portion 413c with the lower lid 42 in a state where the lower lid 42 is in contact with the ground, the upper lid 41 can be detached from the lower lid 42 with one hand.

[0057] While the beverage container of the present invention has been described above based on the illustrated embodiment, the present invention is not limited to this, and the configuration of each part can be replaced with any configuration having a similar function. Furthermore, any other components or steps may be added to the present invention. Furthermore, the present invention may be a combination of any two or more configurations (features) of the above-described embodiments. [Explanation of symbols]
