[0008] The beverage container of this embodiment will be described in detail below 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. <Embodiment> Figure 1 is a perspective view showing a beverage container according to the embodiment. Figure 2 is an exploded perspective view showing a beverage container according to the embodiment. As shown in Figure 2, the beverage container 100 of this embodiment has a container body 1 with an annular opening 11, a lid 2, an inner stopper 3, and a gasket 4.

[0010] The container body 1 is, for example, a cylindrical shape with a bottom and has a vacuum double-wall structure that provides insulation. Examples of materials used for the container body 1 include stainless steel. A beverage is placed inside the container body 1. The beverage may be a carbonated drink. A stepped portion 11a is provided inside the container body 1, against which the packing 4 makes contact.

[0011] As shown in Figure 2, the lid 2 comprises a lid body 20 that covers the outer circumference 11b of the opening 11, and an annular handle 21. Inside the handle 21, there is a housing that accommodates a gripping part, which will be described later.

[0012] Further, the lid portion 2 has an opening 22 at the lower part of the handle 21. In the present embodiment, the front and rear side surfaces of the opening 22 are flat. The surfaces 23, 23 located outside the opening 22 function as an engaged portion with which an opening / closing lever 33 described later engages.

[0013] The middle plug portion 3 is detachable from the lid portion 2. Fig. 2 shows an exploded view of the middle plug portion 3. The middle plug portion 3 has a middle plug housing 31, a stopper member 32, an opening / closing lever (engaging portion) 33, an opening / closing spring 34, a punching shaft (shaft portion) 35, a punching spring 36, and a punching packing 37.

[0014] The middle plug housing 31 has a packing support portion 31a, a gripping portion 31b, and a through hole 31c. The packing support portion 31a supports the lower part of the packing 4. The gripping portion 31b is a portion that a user grips when attaching the lid portion 2 to the container body 1. The through hole 31c is where the punching shaft 35 is inserted.

[0015] The opening / closing lever 33, the opening / closing spring 34, the punching shaft 35, and the punching spring 36 are arranged inside the middle plug housing 31. The stopper member 32 is fixed to the middle plug housing 31. Thereby, the opening / closing lever 33, the opening / closing spring 34, the punching shaft 35, and the punching spring 36 are sandwiched and fixed between the middle plug housing 31 and the stopper member 32. The opening / closing lever 33 has a lever gripping portion 33a and a through hole 33b.

[0016] The lever gripping portion 33a is a portion that a user grips when detaching the lid portion 2 from the container body 1. The punching shaft 35 is inserted into the through hole 33b. Two protrusions 35a, 35a are provided at a side portion slightly below the central portion of the punching shaft 35 at an interval of 180 degrees.

[0017] The pressure relief spring 36 biases the pressure relief shaft 35 upward in the plane of the paper. The pressure relief packing 37 is attached to the lower end of the pressure relief shaft 35 after it has passed through the through hole 31c. When the pressure relief spring 36 is biasing the pressure relief shaft 35, the pressure relief packing 37 comes into contact with a recess provided on the lower surface of the packing support portion 31a, and closes the through hole 31c.

[0018] For example, as shown in Figure 1, when the lid 2 is attached to the container body 1, if the user pushes down the pressure relief shaft 35 against the biasing force of the pressure relief spring 36, the pressure relief packing 37 moves downward, and the gas inside the container body 1 is discharged to the outside through the through hole 31c. In this way, the main part of the pressure relief section that discharges gas from the container body 1 to the outside is formed by the pressure relief shaft 35, the pressure relief spring 36, the pressure relief packing 37, and the recess provided on the lower surface of the packing support part 31a. Figure 3 is a diagram illustrating the opening and closing lever.

[0019] The opening / closing lever 33 is provided with sloped sections 33c, 33c in the parts corresponding to the projections 35a, 35a. The sloped sections 33c, 33c have a gradient, and when the pressure relief shaft 35 is inserted into the through hole 33b, the projections 35a, 35a come into contact with the sloped surfaces of the sloped sections 33c, 33c.

[0020] As shown in Figure 3, the opening / closing lever 33 is rotatable clockwise or counterclockwise around the pressure relief shaft 35 as its axis of rotation. The opening / closing lever 33 is biased clockwise around the pressure relief shaft 35 by the opening / closing spring 34. That is, if the opening / closing lever 33 is grasped and rotated to a certain extent counterclockwise while the inner plug 3 is not attached to the lid 2, and then released, the opening / closing lever 33 will rotate clockwise due to the biasing force of the opening / closing spring 34.

[0021] Furthermore, the opening / closing lever 33 is equipped with a projection 33d. When the opening / closing lever 33 rotates clockwise due to the biasing force of the opening / closing spring 34, this projection 33d comes into contact with a contact portion (not shown) of the stopping member 32, causing the opening / closing lever 33 to stop at a predetermined position (hereinafter referred to as the stopping position). As shown in Figure 2, the stopping position is the position where, in a plan view, the lever gripping portion 33a of the opening / closing lever 33 intersects approximately perpendicularly with the gripping portion 31b.

[0022] Incidentally, as shown in Figure 3, when the opening / closing lever 33 rotates counterclockwise, the inclined portions 33c, 33c exert a downward force on the protrusions 35a, 35a. Consequently, the pressure relief shaft 35 descends. This allows the lid 2 to be easily detached from the container body 1. The mechanism for detaching the lid 2 using this operation will be described in detail later. Figure 4 is a diagram illustrating the positional relationship between the packing and the inner plug.

[0023] The packing 4 is positioned to surround the inner plug portion 3. As mentioned above, the lower part of the packing 4 abuts against the packing support portion 31a. In the following description, the inner plug portion 3 on which the packing 4 is positioned will be referred to as the "inner plug portion 3 with packing". Next, an example of how to use the beverage container 100 of the embodiment will be described. Figures 5 to 8 illustrate the process of attaching the inner stopper with packing to the lid. Figures 5 to 8 show a cross-section of the lid 2.

[0024] When a user attaches the inner stopper part 3 with the packing to the lid part 2, they grasp the gripping part 31b by hooking it with, for example, their index and middle fingers, and grasp the handle 21 with their thumb. Then, they apply force in the direction that brings the gripping part 31b closer to the handle 21. Alternatively, the user grasps the lower surface of the packing support part 31a with both thumbs, and applies upward force to push the lower surface of the packing support part 31a by pinching the handle 21 of the lid part 2 with both index and middle fingers.

[0025] As shown in Figure 5, the lid portion 2 has a guide 24. The guide 24 has an inclined surface 24a, and when a force is applied to move the lever grip portion 33a upward in Figure 5 while the lever grip portion 33a is in contact with the inclined surface 24a of the guide 24, the guide 24 rotates the lever grip portion 33a counterclockwise against the biasing force of the opening / closing spring 34, as shown in Figures 6 and 7.

[0026] As shown in Figure 8, the lever gripping portion 33a, having passed through the inclined surface of the guide 24, is supported by the front surface and the rear side surface of the opening 22. Figure 8 shows the rear side surface 22a of the opening. The upper side surface 4a of the packing 4 moves upward while sliding against the side surface 25 provided on the lid portion 2. The upper surface 4b of the packing 4 then contacts the packing contact portion 26 provided on the lid portion 2. In this state, even if you release your hand from the inner stopper portion 3 with the packing, the inner stopper portion 3 with the packing will not fall out due to the friction between the side surface 4a and the side surface 25 of the packing 4 and will be held inside the lid portion 2. In this embodiment, the lid portion 2 is attached to the container body 1 from this state.

[0027] When attaching the lid 2 to the container body 1, the user moves the grip portion 31b close to the handle 21, resisting the elasticity of the packing 4. When the grip portion 31b approaches the handle 21, portion 4c of the packing 4 is squeezed between the packing contact portion 26 and the packing support portion 31a and begins to contract (deform). Figure 9 illustrates the lid when attached to the container body. Note that the container body 1 is not shown in Figure 9.

[0028] As shown in Figure 9, the opening / closing lever 33 is positioned above the opening side surface 22a. When the pressure on the lever gripping portion 33a by the opening side surface 22a is released, the opening / closing lever 33 rotates clockwise while sliding along the surface 23 due to the biasing force of the opening / closing spring 34, and stops at the stopping position. At this time, the gripping portion 31b is housed in the housing portion 21a provided inside the handle 21, and becomes integrated with the handle 21.

[0029] The position at which the opening / closing lever 33 begins to rotate clockwise while sliding on the surface 23 due to the biasing force of the opening / closing spring 34 is an example of an engagement start / disengagement position. Figure 8 shows the engagement start / disengagement position of the embodiment with a circular dotted line. The guide 24 and the opening side surface 22a are examples of guide parts that guide the gripping part 31b to the engagement start / disengagement position. Figure 10 is a cross-sectional view of the beverage container at the stopping position.

[0030] The portion 4c, whose radius has increased due to the contraction of the packing 4, is supported at the top and sides by the step of the stepped portion 11a. In addition, the lower part of the packing 4 is supported by the packing support portion 31a. As a result, the packing 4 covers the opening 11 from the inside, and even if the user grips the handle 21 and applies force that would cause the lid 2 to detach from the container body 1, the lid 2 will not detach from the container body 1. Therefore, the user can carry the beverage container 1 by, for example, gripping the grip portion 31b with their index and middle fingers and gripping the handle 21 with their thumb.

[0031] Furthermore, the upper side surface 4a of the packing 4 is in contact with the side surface 25 provided on the lid 2, and the upper surface 4b of the packing 4 is in contact with the packing contact portion 26 provided on the lid 2. In addition, the pressure-relieving packing 37 is in contact with the recess 31d provided on the back surface of the packing support portion 31a. As a result, the inside of the container body 1 is kept airtight by the packing 4 and the pressure-relieving packing 37.

[0032] In the state shown in Figure 10, the user can press the pressure relief shaft 35 downwards, causing the pressure relief packing 37 to separate from the recess 31d, and allowing the gas inside the container body 1 to be discharged to the outside through the through hole 31c without having to detach the lid 2 from the container body 1. When the user releases their hand from the pressure relief shaft 35, the pressure relief shaft 35 moves upward due to the biasing force of the pressure relief spring 36, and the pressure relief packing 37 closes the recess 31d. Next, we will explain the operation when a user drinks the beverage in the beverage container 1, that is, when the lid 2 is detached from the container body 1. Figure 11 illustrates the operation when the lid of the embodiment is detached from the container body.

[0033] As shown in Figure 11, the user grasps the lever grip portion 33a of the opening / closing lever 33 and rotates it counterclockwise. As explained in Figure 3, when the opening / closing lever 33 rotates counterclockwise, a force acts to push down the projections 35a, 35a that abut the sloped portions 33c, 33c. This causes the pressure relief shaft 35 to descend. Consequently, the pressure relief packing 37 moves downward and separates from the recess 31d. As a result, the gas inside the container body 1 passes through the through hole 31c and is discharged to the outside. When the user further grasps the lever grip portion 33a of the opening / closing lever 33 and rotates it counterclockwise, as shown in Figure 12, the lever grip portion 33a detaches from the surface 23 and falls into the opening 22. The rotation angle from the stopping position until the lever grip portion 33a detaches from the surface 23 and falls into the opening 22 (when the engagement with the lid portion 2 is released) is, for example, 30 to 60°. As a result, the entire inner stopper portion 3 moves downward. Furthermore, due to the elasticity of the packing 4 itself, part 4c of the packing 4 stretches and separates from the stepped portion 11a. As described above, as shown in Figure 13, the user can detach the lid 2 from the container body 1 and drink the beverage inside.

[0034] Furthermore, when the lid 2 is detached from the container body 1, the airtight seal of the container body 1, which is maintained by the packing 4, is released, and the gas inside the container body 1 is discharged to the outside, all in a synchronized manner.

[0035] As described above, the beverage container 100 of the embodiment includes a container body 1 having an opening 11 for storing beverages inside, a lid 2 having an annular handle 21 that covers the outer circumference of the opening 11, a packing 4 that deforms to cover the opening 11 from the inside and keep the container body 1 airtight, an opening / closing lever 33 that engages with the lid 2 to maintain the deformed state of the packing 4, a gripping part 31b having a shape corresponding to the handle 21, which deforms the packing 4 when brought close to the handle 21 and engages the opening / closing lever 33 with the surface 23, and a pressure relief part (pressure relief shaft 35, pressure relief spring 36, pressure relief packing 37, recess 31d) that operates in conjunction with the release of the airtight seal of the container body 1 maintained by the packing 4 when the engagement between the opening / closing lever 33 and the surface 23 is released, and discharges gas inside the container body 1 to the outside. Therefore, when the lid 2 is detached from the container body 1, the airtight seal of the container body 1, which is maintained by the packing 4, and the operation of releasing the gas inside the container body 1 to the outside can be performed in conjunction.

[0036] As a result, when detaching the lid 2 from the container body 1, the user does not need to push down the pressure relief shaft 35. By gripping the lever grip 33a and rotating it counterclockwise, the pressure relief packing 37 moves downward before the airtight seal of the container body 1, which is maintained by the packing 4, is released, and the gas inside the container body 1 is discharged to the outside through the through hole 31c. Therefore, the lid 2 can be easily detached from the container body 1.

[0037] Furthermore, the inner plug portion 3 has an opening / closing spring 34 that biases the lever grip portion 33a toward the stop position when attached to the lid portion 2, and is equipped with a guide portion (guide 34, opening side surface 22a) that guides the lever grip portion 33a to the engagement start / release position against the biasing force of the opening / closing spring 34 when the inner plug portion 3 is attached to the lid portion 2, and when the lever grip portion 33a reaches the engagement start / release position, the lever grip portion 33a engages in a predetermined position due to the biasing force of the opening / closing spring 34. As a result, when attaching the inner plug portion 3 with a packing to the lid portion 2 with the opening / closing lever 33 in the stop position, the inner plug portion 3 can be attached to the lid portion 2 simply by gripping the grip portion 31b with, for example, the index finger and middle finger and gripping the handle 21 with the thumb, and applying force in the direction that brings the grip portion 31b toward the handle 21. Therefore, compared to beverage containers (different from beverage container 100) in which the user pre-positions the gripping part and then attaches the inner stopper to the lid, the effort required for attachment can be reduced.

[0038] 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]
