Embodiments for Carrying Out the Invention

[0008] Hereinafter, the beverage container of the embodiment will be described in detail with reference to the drawings.

[0009] The positions, sizes, shapes, and ranges of the components shown in the following drawings may not represent their actual positions, sizes, shapes, and ranges in order to facilitate understanding of the invention. Therefore, the present invention is not necessarily limited to the positions, sizes, shapes, and ranges disclosed in the drawings. In the embodiments, elements expressed in the singular form shall include the plural form unless otherwise clearly indicated in the text. <First Embodiment>

[0010] Figure 1 is a perspective view showing a beverage container according to the first embodiment. Figure 2 is an exploded perspective view showing a beverage container according to the first embodiment. Figure 3 is a perspective view illustrating the container body according to the first embodiment. The beverage container 1 of this 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 Figure 3. The beverage is not particularly limited, but examples include water, tea, and coffee. As shown in Figure 3, a lid placement section 22 is located below the opening 21, where a part of the lid 3 (including the lock switch 321 shown in Figure 2) is placed. Below the lid placement section 22, there is a threaded portion 23 that screws into the threaded portion of the lid 3. As shown in Figure 3, the lid placement section 22 is located on the opening 21 side of 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 the flow path for the beverage that flows out from the storage section 20.

[0012] The lid 3 is attached to the container body 2 so as to cover the opening 21. The lid 3 is attached to the container body 2 so as to cover the opening 21 and has a flow path for discharging the beverage from the storage section 20. Note that symbols not explained in Figures 1 to 3 will be explained later. Figure 4 is an exploded perspective view of the beverage container according to the embodiment. Figures 5 and 6 are exploded views of the lid according to the embodiment.

[0013] The lid section 3 includes an upper lid 31, a lower lid 32, and a flow path opening / closing mechanism 33. Part of the structure of the lower lid 32 and the flow path opening / closing mechanism 33 form an opening / closing mechanism for opening and closing the flow path when discharging beverages from the storage section 20.

[0014] As shown in Figure 5, the top cover 31 has a top portion 311 and side portions 312 that cover the opening of the bottom cover 32. The top cover 31 is also provided with a lever 313 and a protrusion 314. The protrusion 314 is an example of a fitting portion. The lever 313 is provided with a shaft pressing portion 313a. When a user pushes the lever 313 downwards, for example with their thumb, the shaft pressing portion 313a can press the tip of the shaft 334. The protrusion 314 is provided in the area corresponding to the lock switch 321 and is a plate-shaped member that protrudes inward from the side of the top cover 31. As shown in Figure 6, the lower cover 32 is provided with a pair of lock switches 321, 321, a screw-in portion 322, a lever placement portion 323, and a flow path 324, all separated by 180 degrees.

[0015] The lock switches 321, 321 are part of the locking mechanism used to secure the top cover 31 to the bottom cover 32. The locking mechanism provided by the lock switches 321, 321 will be described in detail later. The main part of the support is formed by the protrusion 314 and the lock switch 321, which support the upper cover 31 so that it does not separate from the lower cover 32. The threaded portion 322 is threaded into the threaded portion 23.

[0016] The lever arrangement section 323 has a shape corresponding to the lever 313. The lever 313 is positioned in the lever arrangement section 323 when the upper cover 31 is fixed to the lower cover 32. The flow path 324 is the flow path for the beverage flowing out from the storage section 20. The packing 325 shown in Figure 4 prevents the beverage inside the container body 2 from entering areas other than the flow path 324. Note that the packing 325 is not shown in Figure 6.

[0017] The flow path opening / 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. The lock rings 331 and 332, spring 333, packing 335, spring 336, base 337, and packing 338 are attached to the shaft 334.

[0018] The lock ring 331 engages with an engaging portion 334a provided on the shaft 334. This lock ring 331 serves to secure the spring 333 to the shaft 334. The lock ring 331 can be released from its engagement with the engaging portion 334a by rotation and can be detached from the shaft 334. The lock ring 332 is movable in the axial direction of the shaft 334, but when it comes into contact with a protrusion 334b ​​located in the middle of the shaft 334, its further movement toward the lock ring 331 is restricted. The packing 335 prevents the beverage inside the container body 2 from entering any passage other than the flow path 324 of the lower lid 32.

[0019] The spring 336 is compressed between the lock ring 332 and the base 337, biasing the lock ring 332 and causing the lock ring 332 to come into contact with the protrusion 334b ​​located in the middle of the aforementioned shaft 334.

[0020] The base 337 has a circular shape that is slightly raised towards the center. An opening (described later) is provided in the center of the base 337 through which the shaft 334 of the base 337 is inserted. The base 337 is in contact with the packing 325 due to the biasing force of the spring 333. By moving the base 337 downwards in the plane of the paper, the beverage inside the container body 2 can be poured into the flow path 324. The packing 338 seals the opening in the base 337 through which the shaft 334 is inserted. Figure 7 illustrates the arrangement of the lower cover and the flow path opening / closing mechanism. As shown in Figure 7, the lower cover 32 is provided with a shaft receiving portion 326.

[0021] The shaft support portion 326 is a long, narrow tube with openings at both ends 326a and 326b. The shaft 334 is positioned inside this shaft support portion 326. Furthermore, a recess 327 corresponding to the shape of the lock ring 332 (for accommodating the lock ring 332) is provided near the end portion 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, sandwiched between the lock ring 331 and the base 326c, biasing the shaft 334 upward in the drawing direction.

[0023] Furthermore, the base 337 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 when viewed from the side. Next, the locking mechanism using the lock switch 321 will be explained with reference to Figures 7 to 9. Figures 8 and 9 are side cross-sectional views illustrating the locking mechanism using a lock switch. Each lock switch 321 has a hook portion 321a, a recess 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 pivotally supported by the shaft of the bearing portion 321d, and can rotate clockwise and counterclockwise around the bearing portion 321d.

[0025] The hook portion 321a is biased outward from the lower cover 32 by a spring 321e. Specifically, the hook portion 321a on the left side of Figure 7 is biased to the left side of the paper by a spring 321e. The hook portion 321a on the right side of Figure 7 is biased to the right side of the paper by a spring 321e.

[0026] As shown in Figures 7 to 9, when the user grasps the end of the upper cover 31 and brings it close to the lower cover 32, the hook portion 321a contacts the protrusion 314. When the user applies further downward pressure to the upper cover 31 against the biasing force of the spring 321e, the hook portion 321a moves to the inside of the lower cover 32 (for example, the hook portion 321a on the left in Figure 7 moves to the right side of the page), and the protrusion 314 moves over the tip of the hook portion 321a. Once the protrusion 314 moves over the tip of the hook portion 321a, the hook portion 321a moves to the outside of the lower cover 32 due to the biasing force of the spring 321e, and the protrusion 314 is positioned in the recess 321b and fitted and fixed with the hook portion 321a. In addition, the shaft pressing portion 313a contacts the tip of the shaft 334. Furthermore, the contact surfaces of the hook portion 321a and the protrusion 314 have a sloping shape when viewed from the side, so that the hook portion 321a can easily move to the inside of the lower cover 32 when the protrusion 314 presses against it. Figure 10 is a side cross-sectional view illustrating the unlocking mechanism.

[0027] To detach the upper cover 31 from the lower cover 32, the user can grasp either of the pressing parts 321c (the right pressing part 321c in Figure 10) and apply force to compress the spring 321e, thereby releasing the engagement between the right hook part 321a and the protrusion 314 in Figure 10. In this state, by rotating the upper cover 31 counterclockwise around the engagement point between the left hook part 321a and the protrusion 314 as the center of rotation and lifting it upward, the protrusion 314 can be separated from the right hook part 321a.

[0028] By releasing the engagement of one of the lock switches 321, 321 located at both ends and rotating the other engagement part around the center of rotation, the other engagement part (circled in Figure 10) can be easily separated from the protrusion 314 on the left hook part 321a by moving the top cover 31, for example, in the direction of the arrow in Figure 10, without having to press the pressing part 321c. Next, an example of how to use the beverage container 1 of the first embodiment will be explained using Figures 7 to 9.

[0029] The user attaches the flow path opening / closing mechanism 33 to the lower cover 32. Specifically, the shaft 334, to which the lock ring 332, packing 335, spring 336, base 337, and packing 338 are attached, is inserted into the shaft receiving portion 326 from end 326b towards end 326a. Then, the spring 333 is positioned to surround the shaft receiving portion 326, the upper end of the spring 333 is held down by the lock ring 331, and the lock ring 331 is rotated 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 comes into contact with the packing 325.

[0030] Next, the user grasps the end of the upper lid 31 and brings it close to the lower lid 32, and engages the two lids using the lock switch 321. This supports the upper lid 31 on the lower lid 32.

[0031] The user then grasps the lid 3 and rotates it clockwise within the lid placement section 22, thereby engaging the threaded portion 322 with the threaded portion 23. This secures the lid 3 to the container body 2. Figures 11 and 12 illustrate a beverage container when the threaded portion is screwed into the threaded portion.

[0032] As shown in Figure 11, when the threaded portion 322 is screwed into the threaded portion 23, the lock switch 321 is positioned inside the lid mounting portion 22, making it invisible from the outside, and preventing the user from operating the lock switch 321. This prevents the upper lid 31 from coming off the lower lid 32 due to some malfunction. Figures 13 and 14 illustrate an example of the use of a beverage container according to the first embodiment.

[0033] When the user pushes down the lever 313, the shaft pressing portion 313a contacts the tip of the shaft 334, causing the shaft 334 to move downward against the biasing force of the spring 333. Consequently, the base 337 also moves downward, forming a gap s (circled by a dotted line) between the packing 325 and the upper surface 337a of the base 337, allowing the beverage to pass through, as shown in Figure 14. When the lever 313 is pushed in, it contacts the bottom 323a of the lever mounting portion 323. This causes the shaft 334 to stop in its downward position. When the beverage container 1 is tilted to a certain extent in this state, the beverage passes through this gap s. The beverage that has passed through the gap s is then discharged to the outside through the flow paths 324 and 25.

[0034] Furthermore, if the pressure inside the storage section 20 is higher than atmospheric pressure due to temperature differences or other factors, when the shaft pressing section 313a contacts the tip of the shaft 334 and the shaft 334 begins to move downward, the shaft 334 moves downward before the base 337 (before the base 337 begins to move), as shown in Figure 13. This is because the surface area of ​​the packing 338 is smaller than the surface area of ​​the lower surface of the base 337, and therefore the force exerted by the pressure inside the container body 2 is smaller than that on the base 337.

[0035] When the shaft 334 moves downward before the base 337, a gap is formed between the packing 338 and the opening in the base 337 through which the shaft 334 is inserted, allowing the pressure inside the reservoir 20 to pass through. The pressure inside the reservoir 20 escapes through this gap (pressure release mechanism). As a result, the user can move the base 337 downward with less force than would be possible without the pressure release mechanism. When the pressure inside the reservoir 20 returns to atmospheric pressure and the base 337 moves downward, the packing 338 closes the opening in the base 337 through which the shaft 334 is inserted.

[0036] When the user releases their hand from the lever 313, the base 337 is biased by the spring 333 and moves upward, coming into contact with the packing 325. This results in the state shown in Figure 12, and the inside of the storage section 20 is once again kept airtight. Incidentally, the beverage container 1 of this embodiment is equipped with a mechanism to suppress malfunction of the lock switch 321. Next, we will explain the mechanism for suppressing malfunction of the lock switch 321. Figure 15 illustrates a mechanism for suppressing malfunction of the lock switch in the first embodiment.

[0037] If a force is applied to separate the upper cover 31 from the lower cover 32 without using the lock switch 321 (for example, if the upper cover 31 is forcibly pulled upward without releasing the screwed state between the threaded portion 322 and the threaded portion 23 from the state shown in Figure 11), the protrusion 314 presses the hook portion 321a in the direction that compresses the spring 321e, causing the hook portion 321a to move slightly inward. At this time, the end 321f of the lock switch 321 opposite to the hook portion 321a, with the bearing portion 321d in between, comes into contact with the side of the cover placement portion 22, restricting the movement of the hook portion 321a, i.e., preventing the hook portion 321a from going over the tip of the protrusion 314. Therefore, the engagement between the hook portion 321a and the protrusion 314 is not released, and the upper cover 31 can be prevented from separating from the lower cover 32.

[0038] As described above, the beverage container 1 of the first embodiment has a container body 2 having a storage section 20 for storing beverages and an opening 21 for beverages to enter and exit, and a lid 3 attached to the container body 2 so as to cover the opening 21 and opening and closing the flow path when discharging beverages from the storage section 20. The lid 3 has a lower lid 32 having an opening, a flow path opening and closing mechanism 33 attached to the lower lid 32 that opens and closes the flow path by a predetermined operation, an upper lid 31 that covers the opening of the lower lid 32, and a lock switch 321 that supports the upper lid 31 so as not to separate from the lower lid 32. When the lid 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. Therefore, it is possible to prevent the lid from coming off due to malfunction. Therefore, it is not necessary to provide a separate locking mechanism or the like to prevent the release of the lock switch 321. Furthermore, when the lid 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] Furthermore, by devising the structure of the container body 2 and positioning the lid placement section 22 right next to the lock switch 321, a mechanism is provided to suppress malfunctions of the lock switch 321 by restricting its movement, thereby preventing unintended malfunctions by the user.

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

[0041] In this embodiment, a pair of lock switches 321 and protrusions 314 are provided, but the combination is not limited to this; one pair of lock switches 321 and protrusions 314 may be used. <Second Embodiment> Next, a beverage container according to the second embodiment will be described.

[0042] The following description focuses on the differences between the beverage container of the second embodiment and the first embodiment described above. Similar items (parts that have the same function as the first embodiment, even if their shape is slightly different) are denoted by the same reference numerals as in the first embodiment, and detailed explanations are omitted. Figure 16 is a perspective view showing a beverage container according to the second embodiment. The beverage container 1a of the second embodiment shown in Figure 16 differs from the beverage container of the first embodiment in the configuration and placement of the lock switch. The beverage container 1a of the second embodiment has a container body 2 and a lid 4. Figure 17 is a perspective view illustrating the lid portion of the second embodiment. The lid portion 4 includes an upper lid 41, a lower lid 42, and a flow path opening / 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 examples of first fitting parts. The holes 421a and 421b are examples of first fitted parts.

[0044] The lower cover 42 is provided with a threaded portion 322, a flow path 324, and a packing 325. The holes 421a and 421b are positioned so as not to obstruct the flow path 324 (in this embodiment, slightly above the flow path 324). Figure 18 is a perspective view illustrating the top cover of the second embodiment.

[0045] The lever 411 is provided with a shaft pressing portion 411a. When a user pushes the lever 411 downwards, for example with their thumb, the shaft pressing portion 411a can press against the tip of the shaft 334.

[0046] Furthermore, the top cover 41 is provided with a push switch 413 and a housing 414. The push switch 413 has hook portions 413a and 413b and a pressing portion 413c. The hook portions 413a and 413b are examples of second fitting portions. In this embodiment, the hook portions 413a and 413b and the pressing portion 413c are formed from a single component. The push switch 413 is biased by a spring (described later) in the direction of pushing the pressing portion 413c out of the housing 414. By pressing the pressing portion 413c, the hook portions 413a and 413b move into the housing 414 as the pressing portion 413c moves. By releasing the hand from the pressing portion 413c, the hook portions 413a and 413b pop out of the housing 414 to the position shown in Figure 18 as the pressing portion 413c moves.

[0047] As shown in Figure 18, the hooks 412a, 412b and 413a, 413b are positioned approximately 180 degrees apart in a plan view (when viewing the beverage container 1a from above). Figure 19 is a perspective view illustrating the lower cover of the second embodiment. The lower cover 42 is provided with a push switch placement area (notch) 422 that corresponds to the push switch 413.

[0048] Furthermore, the lower cover 42 is provided with hook receiving portions 423a and 423b at positions corresponding to the hook portions 413a and 413b. The hook receiving portions 423a and 423b are examples of second fitting portions. The hook receiving portions 423a and 423b have recesses for accommodating the hook portions 413a and 413b. Figure 20 is a plan view showing the lid of the second embodiment, and Figure 21 is a cross-sectional view taken along line AA in Figure 20.

[0049] When the upper cover 41 is fitted onto the lower cover 42, the hook portions 412a and 412b are located within the holes 421a and 421b, respectively. The hook portions 413a and 413b are located within the recesses of the hook receiving portions 423a and 423b, respectively. As previously mentioned, the push switch 413 is biased by the spring 415 in the direction of pushing the pressing portion 413c out of the 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 / closing mechanism 33 to the lower cover 42. Figure 22 is a diagram illustrating the method of attaching the top cover to the second embodiment.

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

[0051] If the user further increases the force with which they press the hook portions 413a and 413b against the hook receiving portions 423a and 423b, the spring 415 will contract further, causing the hook portions 413a and 413b to overcome the slopes of the hook receiving portions 423a and 423b, and the hook portions 413a and 413b will be positioned in the recesses provided by the hook receiving portions 423a and 423b. The user may also assist in the overcoming of the overhang by pressing the pressing portion 413c when the hook portions 413a and 413b overcome the slopes of the hook receiving portions 423a and 423b. Furthermore, in order to facilitate the contraction of the spring 415 when the hook portions 413a and 413b press against the hook receiving portions 423a and 423b, the contact surfaces of the hook portions 413a and 413b with the hook receiving portions 423a and 423b are each obliquely sloped in a side view.

[0052] The user then grasps the lid 4 and rotates it clockwise within the lid placement section 22, thereby engaging the threaded portion 322 with the threaded portion 23. This secures the lid 4 to the container body 2. Figure 23 is a plan view showing a beverage container according to the second embodiment, and Figure 24 is a cross-sectional view taken along line BB in Figure 23.

[0053] In this second embodiment of the beverage container 1a, when the threaded portion 322 is screwed into the threaded portion 23, the push switch 413 is positioned inside the lid placement portion 22, making it invisible from the outside, and preventing the user from operating the push switch 413 (pressing portion 413c). This prevents the upper lid 41 from coming off the lower lid 42 due to some malfunction.

[0054] To detach the lid 4 from the container body 2, the user grasps the lid 4 and rotates it counterclockwise to release the threaded portion 322 from the threaded portion 23.

[0055] To detach the upper cover 41 from the lower cover 42, the user presses the pressing part 413c to lift the upper cover 41, using the part where the hooks 412a and 412b are fitted with the holes 421a and 421b as the axis of rotation. This releases the engagement between the hooks 413a and 413b and the hook receiving parts 423a and 423b (as shown in Figure 22).

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

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