[0009] [Embodiment 1] <Revolving stopper beverage container> Fig. 2 is a schematic perspective view of a container according to this embodiment. As shown in Fig. 2, the container 2 according to this embodiment includes a container body 4 and a lid 6. The container 2 according to this embodiment is a container for holding a liquid such as a beverage inside the container body 4 and sealing the liquid inside the container body 4 with the lid 6.

[0010] The lid 6 is configured to be detachable from the container body 4. The lid 6 is attached to the container body 4 by screwing the lid 6 and the container body 4 together using a method described below. The lid 6 can be removed from the container body 4 by releasing the screw connection using a method described below.

[0011] Fig. 1 is a schematic cross-sectional view of position A indicated by a dotted line in Fig. 2 as viewed in the direction DA indicated by the arrow, illustrating the interior of container body 4 and lid 6 of container 2. Fig. 3 is a schematic exploded view showing each part of lid 6 of container 2. Note that Figs. 1 and 2 show a state in which lid 6 seals the interior of container body 4.

[0012] As shown in Figure 1, the container body 4 is an insulated container that includes an inner wall 8, an outer wall 10, and a vacuum layer 12 sealed between the inner wall 8 and the outer wall 10. The container body 4 also has an opening 14 that connects the inside and the outside, and stores a liquid or the like that is poured into the container body 4 through the opening 14. The container body 4 includes a resin part 16 that includes a drinking spout that comes into contact with the mouth of the user when the user of the container 2 directly places their mouth on the container body 4 to drink a beverage or the like, and a body thread 18 formed on the resin part 16.

[0013] The container body 4 may have any of various conventionally known shapes as long as the opening 14 can be closed by the lid 6. The inner wall 8 and the outer wall 10 of the container body 4 may be made of various metal materials including stainless steel, and the resin part 16 may be made of various resin materials including polypropylene.

[0014] 1 and 3, the lid portion 6 is provided with a packing 20, and is provided with a first packing holder 22 and a second packing holder 24 as packing holders that restrain the packing 20 relative to the lid portion 6. The packing 20 may be made of a material that is more flexible than the container body portion 4, such as silicone rubber, and the first packing holder 22 and the second packing holder 24 may be made of a material that is more rigid than the packing 20, such as polypropylene.

[0015] The packing 20 has a protruding portion 26 that protrudes beyond the periphery. As shown in FIG. 1 , when the lid portion 6 closes the opening 14, the protruding portion 26 of the packing 20 comes into close contact with the opening 14 of the container body 4. Therefore, when the lid portion 6 closes the opening 14, the close contact portion between the opening 14 and the packing 20 is sealed. When the lid portion 6 closes the opening 14, the protruding portion 26 of the packing 20 may come into close contact with the opening 14 over the entire circumferential direction of the opening 14. The length R1 of the protruding portion 26 from the periphery is 6 mm or less at any position.

[0016] As shown in FIG. 1 , the first packing holder 22 has a first claw portion 28, and the second packing holder 24 has a second claw portion 30. In this embodiment, the first claw portion 28 and the second claw portion 30 are engaged with each other in a forced fit and hold each other inseparably. This holds the first packing holder 22 and the second packing holder 24 inseparably. Note that the lid portion 6 according to this embodiment is not limited to this, and one of the first packing holder 22 and the second packing holder 24 may have a claw portion. In this case, the claw portion may hold the other first packing holder 22 or second packing holder 24 inseparably.

[0017] 1 and 2, the lid 6 has an outer shell 42 that forms part of the outer surface of the container 2. The outer shell 42 may be made of the same material as the first packing holder 22 or the second packing holder 24. The outer shell 42 may include a fourth claw 46 that engages with a third claw 44 formed on the first packing holder 22. Thus, the outer shell 42 may be inseparably constrained to the first packing holder 22.

[0018] Furthermore, outer shell 42 has lid threads 48 that protrude inward of lid 6 at a position that overlaps with container body 4 when viewed from the side of container 2 with lid 6 closing opening 14. Therefore, by screwing lid threads 48 and body threads 18 together, lid 6 can be detachably attached to container body 4.

[0019] The outer shell 42 is formed at a distance R2 from the tip of the protruding portion 26 of the packing 20. The distance R2 is preferably 12 mm or less. In other words, the lid portion 6 includes the outer shell 42 as a shielding portion distinct from the packing 20 within 12 mm from the tip of the protruding portion 26. The first packing holder 22 and the second packing holder 24 may form part of the outer shell of the lid portion 6, and in this case, the shielding portion may include at least one of the first packing holder 22 and the second packing holder 24.

[0020] The lid portion 6 includes an outer shell gasket 50 shown in Figures 1 and 3. The outer shell gasket 50 is located between the second gasket holder 24 and the outer shell 42 and is in close contact with both the second gasket holder 24 and the outer shell 42. This prevents liquids and the like from entering between the first gasket holder 22 and the outer shell 42 from outside the container 2. The outer shell gasket 50 may be made of the same material as the gasket 20.

[0021] The packing 20 is sandwiched between the first packing holder 22, the second packing holder 24, and the outer shell 42. In other words, the packing 20 is not fastened to the first packing holder 22, the second packing holder 24, and the outer shell 42 by the elastic force of the packing 20, but is arranged in such a way that the space formed between the first packing holder 22, the second packing holder 24, and the outer shell 42 is solid.

[0022] The packing 20 is also provided with a retaining portion 38 at one end, and the dimensions of the retaining portion 38 are set to prevent the packing 20 from slipping out from between the first packing holder 22, the second packing holder 24, and the outer shell 42. In other words, the retaining portion 38 is restrained between the first packing holder 22, the second packing holder 24, and the outer shell 42 due to the three-dimensional obstacles caused by the first packing holder 22, the second packing holder 24, and the outer shell 42, thereby reducing the likelihood of the packing 20 coming off.

[0023] Therefore, in the lid portion 6, the force that the packing 20 applies to the first packing holder 22 and the second packing holder 24 may be equal to or less than a predetermined value. For example, the force that the packing 20 applies to the first packing holder 22 and the second packing holder 24 is equal to or less than 20 N.

[0024] 3, when the first packing holder 22 and the second packing holder 24 restrain the packing 20, the inner diameter of the packing contact portion, which is the portion of the packing 20 that contacts the first packing holder 22, is defined as R3. In this embodiment, the change from R3 when the packing 20 is not restrained by the packing holders to R3 when the packing 20 is restrained by the packing holders is 10% or less.

[0025] 3, when the first packing holder 22 and the second packing holder 24 are restraining the packing 20, the outer diameter of the packing holder contact portion, which is the portion of the first packing holder 22 that contacts the packing 20, is defined as R4. In this embodiment, R4 is 110% or less of R3.

[0026] An air layer 40 is formed as a space between the first packing holder 22, the second packing holder 24, the retaining portion 38, and the outer shell 42. Therefore, the air layer 40 is sealed regardless of whether the opening 14 is opened or closed by the lid portion 6.

[0027] <Example of container manufacturing method> An example of a method for manufacturing the container 2 according to this embodiment will be described with reference to Fig. 4. Fig. 4 is a flowchart for explaining an example of a method for manufacturing the container 2 according to this embodiment.

[0028] In the manufacturing method of the container 2 according to this embodiment, first, each component of the lid portion 6 is molded (step S2). In particular, in this embodiment, the packing 20, the first packing holder 22, and the second packing holder 24 are molded.

[0029] The packing 20 may be molded by a conventionally known silicone rubber molding method. The first packing holder 22 and the second packing holder 24 may be molded by a conventionally known polypropylene molding method. In step S2, each of the components of the lid 6 except for the packing 20, the first packing holder 22, and the second packing holder 24 is also molded. Various conventionally known methods may be used to mold these components depending on the material or shape of each component.

[0030] Next, the components of the lid 6 are assembled (step S4). In particular, step S4 is a joining process in which the first packing holder 22 and the second packing holder 24 are joined together. In this embodiment, the first packing holder 22 and the second packing holder 24 are pressed against each other in a state in which the first claw portions 28 of the first packing holder 22 are in contact with the second claw portions 30 of the second packing holder 24.

[0031] As a result, the first claws 28 and the second claws 30 press against each other, causing the first packing holder 22 and the second packing holder 24 to bend slightly, and eventually the first claws 28 and the second claws 30 climb over each other. As a result, the first packing holder 22 and the second packing holder 24 are forced to engage with each other by the first claws 28 and the second claws 30, and are restrained from separating from each other.

[0032] In the joining step, the packing 20 is placed in advance so that the retaining portion 38 of the packing 20 is located between the first packing holder 22 and the second packing holder 24. By joining the first packing holder 22 and the second packing holder 24 in this state, the first packing holder 22 and the second packing holder 24 restrain the packing 20 so that it cannot be separated.

[0033] In step S4, the components of the lid 6 are also assembled, except for the above-mentioned packing 20, first packing holder 22, and second packing holder 24. Various conventionally known methods may be used to assemble the components, such as force fitting, screw fastening, or adhesive bonding. Through steps S2 and S4, the lid 6 shown in FIG. 1 etc. is manufactured.

[0034] Here, for example, in parallel with steps S2 and S4, the container body 4 is manufactured (step S6). In step S6 in this embodiment, for example, the container body 4 may be manufactured by forming each part of the container body 4 using a conventionally known stainless steel processing method, assembling each part, and forming the vacuum layer 12 using a vacuum chamber.

[0035] In this embodiment, after steps S4 and S6 are completed, the lid 6 is attached to the container body 4 (step S8). Step S8 may be performed, for example, by screwing the lid threads 48 and the body threads 18 together to attach the lid 6 to the container body 4. In this way, the container 2 is manufactured.

[0036] [Variation 1] <Modification of the air layer> A modified example of the container 2 according to this embodiment will be described with reference to FIG. 5. FIG. 5 is a schematic cross-sectional view illustrating the interior of the container body 4 and lid 6 of the container 2 according to this modification. The container 2 according to this modification differs from the container 2 according to this embodiment only in the configuration of the lid 6. Hereinafter, each part of the lid 6 according to each modification may have the same configuration as each part of the lid 6 according to this embodiment, unless otherwise specified. Note that in this specification, the schematic cross-sectional views of the container according to each modification of this embodiment all show a cross-section at the same position as the cross-section shown in FIG. 1.

[0037] In this modified example, the first packing holder 22 and the second packing holder 24 also hold each other inseparably and sandwich the packing 20 to hold it inseparably. Furthermore, when the lid portion 6 closes the opening 14, the packing 20 is in close contact with the opening 14.

[0038] In this modification, the packing 20 is inseparably restrained by the first packing holder 22 and the second packing holder 24 regardless of the presence of the outer shell 42 .

[0039] Furthermore, in this embodiment, the air layer 40 is formed by the packing 20, the first packing holder 22, and the second packing holder 24, regardless of the presence of the outer shell 42. The air layer 40 is sealed between the packing 20 and the first packing holder 22. The sealing of the air layer 40 is maintained regardless of whether the opening 14 is opened or closed by the lid 6. Note that the air layer 40 of the lid 6 according to this modification is not limited to the configuration shown in FIG. 5 , and for example, the air layer 40 may be formed between the packing 20 and at least one of the first packing holder 22 and the second packing holder 24.

[0040] Moreover, most of the surface of the packing 20 according to this modification is in contact with the first packing holder 22 or the second packing holder 24. Therefore, when the lid 6 is removed from the container body 4 to open the opening 14, the total area of ​​the exposed surface of the packing 20 according to this modification is reduced compared to the present embodiment.

[0041] For example, in this modification, the exposed surface area of ​​the packing 20 that is held in an inseparable manner by each packing holder is 50% or less of the total surface area of ​​the packing 20.

[0042] Like the container 2 according to the present embodiment, the container 2 according to this modification may be manufactured according to the flowchart shown in Fig. 4. In this case, the method for molding each member in step S2 and the method for assembling each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0043] [Variation 2] <Holder screw engagement> A modified example of the lid 6 of the container 2 according to this embodiment will be described with reference to Fig. 6. Fig. 6 is a schematic cross-sectional view illustrating the inside of the container body 4 and the lid 6 of the container 2 according to this modification. The container 2 according to this modification differs from the container 2 according to this embodiment only in the configuration of the lid 6.

[0044] The first packing holder 22 included in the lid portion 6 according to this modification has a first screw thread 52, and the second packing holder 24 has a second screw thread 56. In this modification, the first screw thread 52 and the second screw thread 56 are engaged with each other. This prevents the first packing holder 22 and the second packing holder 24 from separating from each other. The first screw thread 52 and the second screw thread 56 may each have a protrusion that restricts relative rotation between the first packing holder 22 and the second packing holder 24 in a direction in which the first screw thread 52 and the second screw thread 56 are disengaged from each other by being forced to engage with each other.

[0045] In this modified example, the first packing holder 22 and the second packing holder 24 also hold the packing 20 in an inseparable manner. Furthermore, when the lid 6 closes the opening 14, the packing 20 is in close contact with the opening 14.

[0046] Like the container 2 according to the present embodiment, the container 2 according to this modification may be manufactured according to the flowchart shown in Fig. 4. In this case, the method for molding each member in step S2 and the method for assembling each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0047] In particular, in the joining step according to this modified example, the first packing holder 22 and the second packing holder 24 are rotated relative to each other in a state in which the first screw thread 52 of the first packing holder 22 and the second screw thread 56 of the second packing holder 24 are in contact with each other. As a result, in the joining step, the first screw thread 52 and the second screw thread 56 are screwed together, and the first packing holder 22 and the second packing holder 24 are joined together.

[0048] [Variation 3] <Screw for locking the holder> Another modified example of the lid 6 of the container 2 according to this embodiment will be described with reference to Fig. 7. Fig. 7 is a schematic cross-sectional view illustrating the inside of the container body 4 and the lid 6 of the container 2 according to this modification. The container 2 according to this modification differs from the container 2 according to this embodiment only in the configuration of the lid 6.

[0049] Compared to the lid 6 according to the present embodiment, the lid 6 according to this modification further includes a screw 60. Furthermore, the first packing holder 22, the second packing holder 24, and the outer shell 42 according to this modification each have a first screw hole 62, a second screw hole 64, and a third screw hole 66 as screw holes. Furthermore, the screw 60 threadably engages with all of the first screw hole 62, the second screw hole 64, and the third screw hole 66. Therefore, in this modification, the first packing holder 22, the second packing holder 24, and the outer shell 42 are inseparably bound to one another by the screw 60.

[0050] In this modified example, the first packing holder 22 and the second packing holder 24 also hold the packing 20 in an inseparable manner. Furthermore, when the lid 6 closes the opening 14, the packing 20 is in close contact with the opening 14.

[0051] Like the container 2 according to the present embodiment, the container 2 according to this modification may be manufactured according to the flowchart shown in Fig. 4. In this case, the method for molding each member in step S2 and the method for assembling each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0052] In particular, in the joining process according to this modified example, the first packing holder 22, the second packing holder 24, and the outer shell 42 are positioned so that the first screw hole 62, the second screw hole 64, and the third screw hole 66 are positioned on a substantially straight line. Next, the screws 60 are screwed into the first screw hole 62, the second screw hole 64, and the third screw hole 66. As a result, the screws 60 hold the first packing holder 22, the second packing holder 24, and the outer shell 42 together so that they cannot be separated from one another.

[0053] [Variation 4] <Joining the holder by melting> Another modified example of the lid 6 of the container 2 according to this embodiment will be described with reference to Fig. 8. Fig. 8 is a schematic cross-sectional view illustrating the inside of the container body 4 and the lid 6 of the container 2 according to this modification. The container 2 according to this modification differs from the container 2 according to this embodiment only in the configuration of the lid 6.

[0054] Compared to the lid part 6 according to the present embodiment, the lid part 6 according to this modification includes a joint part 68 that is continuous with both the first packing holder 22 and the second packing holder 24. The joint part 68 includes materials of both the first packing holder 22 and the second packing holder 24. Therefore, in this modification, the first packing holder 22 and the second packing holder 24 are joined to each other by the joint part 68 inseparably.

[0055] In this modified example, the first packing holder 22 and the second packing holder 24 also hold the packing 20 in an inseparable manner. Furthermore, when the lid 6 closes the opening 14, the packing 20 is in close contact with the opening 14.

[0056] Like the container 2 according to the present embodiment, the container 2 according to this modification may be manufactured according to the flowchart shown in Fig. 4. In this case, the method for molding each member in step S2 and the method for assembling each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0057] In particular, in the joining process according to this modified example, for example, the first packing holder 22 and the second packing holder 24 are brought into contact with each other, and ultrasonic vibrations are propagated to the contact portion to vibrate the contact portion. As a result, frictional heat is generated at the contact portion, causing the first packing holder 22 and the second packing holder 24 to melt. Thereafter, by stopping the ultrasonic vibrations, the melted first packing holder 22 and the second packing holder 24 are mixed together to form a bonded joint 68, and the first packing holder 22 and the second packing holder 24 are joined together in an inseparable manner.

[0058] [Variation 5] <Joining holders using electromagnetic induction heating> Another modified example of the lid 6 of the container 2 according to this embodiment will be described with reference to Fig. 9. Fig. 9 is a schematic cross-sectional view illustrating the inside of the container body 4 and the lid 6 of the container 2 according to this modification. The container 2 according to this modification differs from the container 2 according to this embodiment only in the configuration of the lid 6.

[0059] The lid 6 according to this modification differs in configuration from the lid 6 according to the previous modification only in that it further includes conductive material 70 in the joint 68. In other words, also in this modification, the first packing holder 22 and the second packing holder 24 are inseparably joined to each other by the joint 68.

[0060] In this modified example, the first packing holder 22 and the second packing holder 24 also hold the packing 20 in an inseparable manner. Furthermore, when the lid 6 closes the opening 14, the packing 20 is in close contact with the opening 14.

[0061] The container 2 according to this modification may be manufactured, for example, in the same manner as the container 2 according to this embodiment, according to the flowchart shown in Fig. 4. In this case, the method for molding each member in step S2 and the method for assembling each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0062] In particular, in the joining step according to this modified example, the first packing holder 22 and the second packing holder 24 are brought into contact with each other with the conductive material 70 disposed between them. As a result, the first packing holder 22 and the second packing holder 24 sandwich the conductive material 70 at the contact portion.

[0063] Next, electromagnetic waves of a predetermined frequency are irradiated onto the conductive material 70. As a result, the conductive material 70 is heated by electromagnetic induction heating, and the heated conductive material 70 melts the first packing holder 22 and the second packing holder 24 at the contact portion between the first packing holder 22 and the second packing holder 24. As a result, the above-mentioned joint 68 is formed, and the first packing holder 22 and the second packing holder 24 are joined together inseparably.

[0064] [Variation 6] <Double seal structure> Another modified example of the lid 6 of the container 2 according to this embodiment will be described with reference to Fig. 10. Fig. 10 is a schematic cross-sectional view illustrating the inside of the container body 4 and the lid 6 of the container 2 according to this modification. The container 2 according to this modification differs from the container 2 according to this embodiment only in the configuration of the lid 6.

[0065] In this modified example, the first packing holder 22 and the second packing holder 24 also hold the packing 20 in an inseparable manner. Here, in particular, the packing 20 of the lid 6 according to this modified example further includes a protruding portion 72 that protrudes further than the surrounding area, in addition to the protruding portion 26. Furthermore, like the protruding portion 26, the protruding portion 72 is in close contact with the opening 14. Here, the protruding portion 72 is in close contact with the container body 4 at the periphery of the second opening, which is different from the periphery of the first opening, which is the position of the container body 4 where the protruding portion 26 is in close contact.

[0066] In other words, the packing 20 according to this modification includes the protrusion 26 as a first contact portion that comes into close contact with the periphery of the first opening of the container body 4 when the lid 6 closes the opening 14. The packing 20 according to this modification also includes the protrusion 72 as a second contact portion that comes into close contact with the periphery of a second opening, which is different from the periphery of the first opening of the container body 4, when the lid 6 closes the opening 14.

[0067] The container 2 according to this modification may be manufactured, for example, in the same manner as the container 2 according to this embodiment, according to the flowchart shown in Fig. 4. In this case, the method for molding each member in step S2 and the method for assembling each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0068] [Embodiment 2] <Single-opening stopper beverage container 1> A container 74 according to another embodiment of the present specification will be described with reference to FIGS. 11 to 15. FIG. 11 is a perspective view of the container 74 according to this embodiment, and FIG. 12 is a cross-sectional view of the container 74 shown in FIG. 11 taken along line CD. FIG. 13 is an enlarged schematic view of region E shown in FIG. 12, and is a schematic enlarged view for specifically explaining the lid 6 according to this embodiment, which will be described later. FIG. 14 is a schematic cross-sectional view of the lid 6, showing the same cross-section as that shown in FIG. 12, when a rotating portion and a stopper, which will be described later, are both in the open position. FIG. 15 is a schematic exploded view of the lid 6 according to this embodiment. Hereinafter, each part of the container according to each embodiment may have the same configuration as each part of the container according to any of the embodiments described above, unless otherwise specified.

[0069] Like the container 2 according to the previous embodiment, the container 74 according to this embodiment includes a container body 4 and a lid 6 that opens and closes the opening 14 of the container body 4. As shown in Fig. 11 , the container body 4 according to this embodiment has a plurality of belt holders 76 formed on the outer surface of the container body 4, through which a belt for holding the container 2 can be passed.

[0070] 12 to 14, the lid 6 according to this embodiment includes a packing 20, a first packing holder 22, and a second packing holder 24. In this embodiment as well, the first packing holder 22 and the second packing holder 24 hold each other inseparably and sandwich the packing 20 to hold it inseparably. Furthermore, when the lid 6 closes the opening 14 of the container body 4, the packing 20 is in close contact with the opening 14. In this embodiment as well, the lid 6 may be detachably attached to the container body 4 by threading the body thread 18 and the lid thread 48 together.

[0071] 12 to 15, the first packing holder 22 according to this embodiment has a discharge port 78, which is an opening that communicates with the inside of the container body 4 via the opening 14. This allows the liquid inside the container body 4 to be taken out of the container body 4 via the opening 14 and the discharge port 78, even when the lid 6 is attached to the container body 4.

[0072] 13 and 15, the cover 6 further includes a pivoting portion 80, a discharge port gasket 82, and a discharge port gasket holder 84. In this embodiment, the pivoting portion 80 and the discharge port gasket holder 84 may each have a fifth claw portion 106 and a sixth claw portion 108 that engage with each other in a forced fit. This prevents the pivoting portion 80 and the discharge port gasket holder 84 from separating from each other. The pivoting portion 80 and the discharge port gasket holder 84 also sandwich the discharge port gasket 82 to prevent it from separating. In other words, the discharge port gasket 82 performs the same function as the gasket 20, the pivoting portion 80 performs the same function as the first gasket holder 22, and the discharge port gasket holder 84 performs the same function as the second gasket holder 24.

[0073] In addition, the cover 6 includes a rotating part shaft 86 that rotatably restrains the rotating part 80 relative to the second packing holder 24. The rotating part shaft 86 is inserted into an opening of a first bearing 112 formed in the second packing holder 24 and an opening of a rotating part bearing 116 formed in the rotating part 80. In this way, the rotating part shaft 86 may rotatably restrain the rotating part 80 relative to the second packing holder 24. Furthermore, the discharge port packing 82 and the discharge port packing holder 84 rotate around the rotating part shaft 86 together with the rotating part 80.

[0074] The rotating unit 80 moves between a closed position shown in FIG. 12 and an open position shown in FIG. 14 by rotating around a rotating unit shaft 86. When the rotating unit 80 is in the closed position, the discharge port packing 82 contacts the first packing holder 22, and in particular, the discharge port packing 82 comes into close contact with the discharge port 78, thereby sealing the discharge port 78. When the rotating unit 80 is in the open position, the discharge port packing 82 moves away from the first packing holder 22, opening the discharge port 78. Note that a force may be applied to the rotating unit 80 by a spring or the like so that the rotating unit 80 always rotates toward the open position. Furthermore, as shown in FIG. 13, the rotating unit 80 may have a sealed air layer 40 between the discharge port packing 82 and the outer shell 42, regardless of whether the rotating unit 80 closes the discharge port 78.

[0075] 12 to 15, the lid portion 6 includes a stopper 88. The stopper 88 has a stopper claw 92 that engages with an outer shell first claw 90 formed on the rotating portion 80 when the rotating portion 80 is in the closed position. Therefore, when the rotating portion 80 and the stopper 88 are both in the closed position, the stopper 88 restrains the rotating portion 80 in the closed position.

[0076] The lid portion 6 also includes a stopper shaft 94 that rotatably restrains the stopper 88 relative to the second packing holder 24. For example, the stopper shaft 94 is inserted into an opening of a second bearing 110 formed in the second packing holder 24 and an opening of a stopper bearing 114 formed in the stopper 88, as shown in FIG. 15 . In this way, the stopper shaft 94 may rotatably restrain the stopper 88 relative to the second packing holder 24. In particular, the stopper 88 moves between the closed position shown in FIG. 12 and the open position shown in FIG. 14 by rotating around the stopper shaft 94. The stopper 88 may be moved between the closed position and the open position by, for example, being gripped and moved by a user of the container 74.

[0077] 12 to 15, the cover 6 includes a push button 96. The push button 96 has a push button claw 100 that engages with an outer shell second claw 98 formed on the pivoting part 80 when the pivoting part 80 is in the closed position. Therefore, when the pivoting part 80 and the push button 96 are both in the closed position, the push button 96 restrains the pivoting part 80 in the closed position.

[0078] The cover 6 includes a push button shaft 102 that rotatably restrains the push button 96 relative to the second packing holder 24. In particular, when the push button 96 is pressed from the outside, it rotates around the push button shaft 102 and moves so as to disengage the outer shell second claw 98 from the push button claw 100. The push button 96 may have a push button protrusion 104 that pushes the rotating portion 80 upward as it rotates around the push button shaft 102.

[0079] Therefore, when the stopper 88 is in the open position and the rotating unit 80 is in the closed position, pressing the push button 96 from the outside allows the rotating unit 80 to rotate about the rotating unit shaft 86 and move to the open position. On the other hand, when the stopper 88 is in the closed position and the rotating unit 80 is in the closed position, even if the push button 96 is pressed from the outside, the stopper 88 restrains the rotating unit 80, so that the rotating unit 80 remains restrained in the closed position. Note that when the push button 96 is not pressed from the outside, it may be maintained in a position that constantly restrains the rotating unit 80 in the closed position by a spring (not shown) or the like.

[0080] The container 74 according to this embodiment may be manufactured, for example, in the same manner as the container 2 according to the previous embodiment, according to the flowchart shown in Fig. 4. In this case, the molding method of each member in step S2 and the assembly method of each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0081] Here, in the joining step according to this embodiment, in addition to joining the first packing holder 22 and the second packing holder 24, the rotating part 80 and the discharge port packing holder 84 are joined together. Here, the rotating part 80 and the discharge port packing holder 84 may be joined together by any of the joining methods for the first packing holder 22 and the second packing holder 24 described above so that the rotating part 80 and the discharge port packing holder 84 sandwich the discharge port packing 82 and restrain it so that it cannot be separated.

[0082] [Embodiment 3] <Food container 1> A container 118 according to another embodiment of the present specification will be described with reference to Figures 16 and 17. Figure 16 is a perspective view of the container 118 according to this embodiment, and Figure 17 is a cross-sectional view of the container 118 shown in Figure 16 taken along the arrow FG line.

[0083] Like the containers according to the above-described embodiments, the container 118 according to this embodiment includes a container body 4 and a lid 6 that opens and closes the opening 14 of the container body 4. Here, the container body 4 according to this embodiment may consist only of a resin part 120 that forms the side and bottom. Furthermore, the container body 4 according to this embodiment may have a top part 122 formed on the side of the resin part 120 opposite the bottom.

[0084] 16 and 17, the lid 6 according to this embodiment includes a packing 20, a first packing holder 22, and a second packing holder 24. In this embodiment as well, the first packing holder 22 and the second packing holder 24 hold each other inseparably and sandwich the packing 20 to hold it inseparably. Furthermore, when the lid 6 closes the opening 14 of the container body 4, the packing 20 is in close contact with the opening 14. In this embodiment, each of the first packing holder 22 and the second packing holder 24 may form part of the outer shell of the lid 6.

[0085] The lid 6 closes the opening 14 of the container body 4 by inserting the top 122 of the container body 4 into the interior of the lid 6. As shown in Figure 17, when the lid 6 closes the opening 14 of the container body 4, the packing 20 tightly contacts the opening 14. In this way, the lid 6 seals the opening 14 of the container body 4.

[0086] In addition, when the lid part 6 closes the opening 14 of the container body part 4, the second packing holder 24 may abut against the side part of the resin part 120 of the container body part 4. Furthermore, the lid part 6 may be removed from the container body part 4 by applying an external force to the second packing holder 24, causing the lid part 6 to bend and releasing the abutment between the second packing holder 24 and the side part of the resin part 120.

[0087] Container 118 according to this embodiment may be manufactured, for example, in the same manner as the containers according to the above-described embodiments, according to the flowchart shown in Fig. 4. In this case, the molding method of each member in step S2 and the assembly method of each member in step S4 may be changed depending on the shape of each part of lid portion 6. Also, in this embodiment, step S8 may be performed by molding resin portion 120 using various conventionally known resin molding methods.

[0088] [Embodiment 4] <Single-opening stopper beverage container 2> A container 124 according to another embodiment of the present specification will be described with reference to Fig. 18. Fig. 18 is a schematic cross-sectional view of the container 124 according to this embodiment. Note that the cross-sectional views of the containers according to the following embodiments show cross sections on a plane that passes through the approximate center of the bottom of the container body 4 of each container and is parallel to the normal direction of the bottom.

[0089] Like the containers according to the above-described embodiments, the container 124 according to this embodiment includes a container body 4 and a lid 6 that closes the opening 14 of the container body 4 in an openable and closable manner.

[0090] The lid 6 according to this embodiment includes a stopper gasket 220 and a stopper gasket holder 222. In this embodiment, the stopper gasket holder 222 holds the stopper gasket 220 in an inseparable manner via an adhesive or the like. In the container 124, the lid 6 may be detachably attached to the container body 4 by threading the body thread 18 formed on the container body 4 with the lid thread 48 formed on the stopper gasket holder 222.

[0091] The plug gasket holder 222 has a discharge port 78. The lid 6 also includes a rotating part 80 that rotates around a rotating part shaft 86 and moves between a closed position and an open position, and a push button 96 that holds the rotating part 80 in the closed position. However, the lid 6 according to this embodiment does not necessarily include the stopper 88.

[0092] The lid portion 6 includes a discharge port gasket 20 (corresponding to the gasket 20 in other embodiments) that tightly contacts the discharge port 78 to seal the discharge port 78 when the pivoting portion 80 is in the closed position. The lid portion 6 further includes a first gasket holder 22 and a second gasket holder 24. The first gasket holder 22 and the second gasket holder 24 inseparably hold each other and sandwich the discharge port gasket 20 in a clamping manner. The first gasket holder 22 and the second gasket holder 24 may each have a fifth claw portion 106 and a sixth claw portion 108 that are engaged with each other in a forced fit. The second gasket holder 24 may be inseparably held by the outer shell 42. In this embodiment, a sealed air layer 40 may be formed between the pivoting portion 80 and the discharge port gasket 20, regardless of whether the discharge port 78 is opened or closed by the discharge port gasket 20.

[0093] The container 124 according to this embodiment may be manufactured, for example, in the same manner as the containers according to the above-described embodiments, according to the flowchart shown in Fig. 4. In this case, the molding method of each member in step S2 and the assembly method of each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0094] [Embodiment 5] <Tumbler> A container 126 according to another embodiment of the present specification will be described with reference to Fig. 19. Fig. 19 is a schematic cross-sectional view of the container 126 according to this embodiment. Like the containers according to the above-described embodiments, the container 126 according to this embodiment includes a container body 4 and a lid 6 that closes the opening 14 of the container body 4 in an openable and closable manner.

[0095] The lid 6 according to this embodiment, like the lid 6 according to embodiment 3, includes a packing 20, a first packing holder 22, and a second packing holder 24. In this embodiment as well, the first packing holder 22 and the second packing holder 24 hold each other inseparably and sandwich the packing 20 to hold it inseparably. Furthermore, when the lid 6 closes the opening 14 of the container body 4, the packing 20 is in close contact with the opening 14.

[0096] In the container 126, the lid 6 may be detachably attached to the container body 4 by threading the body thread 18 formed on the container body 4 with the lid thread 48 formed on the first packing holder 22. Also, in this embodiment, a sealed air layer 40 may be formed between the packing 20 and the second packing holder 24 regardless of whether the lid 6 opens or closes the opening 14 of the container body 4.

[0097] The container 126 according to this embodiment may be manufactured, for example, in the same manner as the containers according to the above-described embodiments, according to the flowchart shown in Fig. 4. In this case, the molding method of each member in step S2 and the assembly method of each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0098] [Embodiment 6] <Cup-type beverage container> A container 128 according to another embodiment of the present specification will be described with reference to Fig. 20. Fig. 20 is a schematic cross-sectional view of the container 128 according to this embodiment. Like the containers according to the embodiments described above, the container 128 according to this embodiment includes a container body 4 and a lid 6 that closes the opening 14 of the container body 4 in an openable and closable manner.

[0099] The lid portion 6 may include a plug gasket 220 and a plug gasket holder 222 that holds the plug gasket 220 in an inseparable manner with an adhesive or the like and has a discharge port 78 that communicates with the opening 14.

[0100] The lid portion 6 includes a discharge port packing 20, a first packing holder 22, and a movable valve 24. The movable valve 24 functions as the second packing holder 24 in other embodiments, as will be described later, and is rotatably constrained relative to the stopper packing holder 222 by a shaft (not shown). The movable valve 24 has a seventh claw 132 that engages with the sixth claw 108 of the first packing holder 22 in a forced fit manner, thereby constraining the first packing holder 22 and the movable valve 24 to prevent separation. The first packing holder 22 and the movable valve 24 also sandwich the discharge port packing 20 to prevent separation. In this embodiment, a sealed air layer 40 may be formed between the discharge port packing 20 and the movable valve 24, regardless of whether the discharge port 78 is opened or closed by the discharge port packing 20.

[0101] The container 128 according to this embodiment may be manufactured, for example, in the same manner as the containers according to the above-described embodiments, according to the flowchart shown in Fig. 4. In this case, the method for forming each member in step S2 and the method for assembling each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0102] [Embodiment 7] <Food container 2> A container 140 according to another embodiment of the present specification will be described with reference to Fig. 21. Fig. 21 is a schematic cross-sectional view of the container 140 according to this embodiment. Like the containers according to the embodiments described above, the container 140 according to this embodiment includes a container body 4 and a lid 6 that closes the opening 14 of the container body 4 in an openable and closable manner.

[0103] The lid 6 according to this embodiment, like the lid 6 according to embodiment 1, includes a packing 20, a first packing holder 22, and a second packing holder 24. In this embodiment, the first packing holder 22 and the second packing holder 24 also hold each other inseparably and sandwich the packing 20 to hold it inseparably. Furthermore, when the lid 6 closes the opening 14 of the container body 4, the packing 20 is in close contact with the opening 14. In the container 140, the lid 6 may be detachably attached to the container body 4 by threading the body thread 18 formed on the container body 4 with the lid thread 48 formed on the outer shell 42 of the lid 6.

[0104] The container 140 according to this embodiment may be manufactured, for example, in the same manner as the containers according to the above-described embodiments, according to the flowchart shown in Fig. 4. In this case, the molding method of each member in step S2 and the assembly method of each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0105] [Embodiment 8] <Pot> A container 142 according to another embodiment of the present specification will be described with reference to Fig. 22. Fig. 22 is a schematic cross-sectional view of the container 142 according to this embodiment. Like the containers according to the above-described embodiments, the container 140 according to this embodiment includes a container body 4 and a lid 6 that opens and closes the opening 14 of the container body 4. Here, the container 142 may include a gripping portion 144 that is formed on the container body 4 and that is used to grip and support the container body 4.

[0106] The lid 6 includes a packing 20, a first packing holder 22, and a second packing holder 24. The first packing holder 22 and the second packing holder 24 hold each other inseparably and sandwich the packing 20 to hold it inseparably. In the container 142, the lid 6 may be detachably attached to the container body 4 by threading the body thread 18 formed on the container body 4 with the lid thread 48 formed on the outer shell 42 of the lid 6. In this embodiment, a sealed air layer 40 may be formed between the packing 20 and the first packing holder 22 regardless of whether the lid 6 opens or closes the opening 14 of the container body 4.

[0107] The lid 6 according to this embodiment may include an additional packing 146 and an additional packing holder 148 that holds the additional packing 146 in an inseparable manner using an adhesive or the like. The additional packing 146 may be in close contact with the opening 14 when the lid 6 is attached to the container body 4.

[0108] The lid 6 according to this embodiment includes a push button 150, a flow path 152, and a discharge port 154. The push button 150 is constrained so as to be movable up and down relative to the outer shell 42. The flow path 152 is formed in the additional packing holder 148, and is located on the side of the container body 4 when the lid 6 is attached to the container body 4, and has an opening 156 that communicates with the opening 14. The discharge port 154 is located at the end of the flow path 152 opposite the opening 156, and communicates between the inside of the flow path 152 and the outside of the container 142.

[0109] Here, when the push button 150 is not pressed down, the packing 20 is in close contact with the opening 156. Therefore, when the push button 150 is not pressed down, the packing 20 seals the opening 156.

[0110] The push button 150 restrains the first packing holder 22. Therefore, when the push button 150 is pressed down by an external force, the first packing holder 22 is pressed down together with the second packing holder 24 and the packing 20.

[0111] When push button 150 is pressed downward, the adhesion between packing 20 and opening 156 is released, and opening 156 is opened. In this state, communication is established between the interior of container body 4 and the outside of container 142 via opening 14, opening 156, flow path 152, and discharge port 154. Push button 150 may be temporarily maintained in a pressed state, or, if push button 150 is pressed further from this state, push button 150 may move upward to its original position. This causes lid 6 to close opening 156 in an openable and closable manner.

[0112] The container 142 according to this embodiment may be manufactured, for example, in the same manner as the containers according to the above-described embodiments, according to the flowchart shown in Fig. 4. In this case, the method for forming each member in step S2 and the method for assembling each member in step S4 may be changed depending on the shape of each part of the lid portion 6, etc.

[0113] <Summary> Each of the containers according to the above-described embodiments includes a container body and a lid that closes the opening of the container body in an openable and closable manner. Each of the lids according to the above-described embodiments includes a packing, a first packing holder, and a second packing holder. The packing is in close contact with the opening when the lid closes the opening. The first packing holder and the second packing holder inseparably restrain each other and sandwich the packing, thereby inseparably restraining the packing.

[0114] With the above-described configuration, the lid portion according to each of the above-described embodiments can be manufactured by joining the first packing holder and the second packing holder so that the first packing holder and the second packing holder hold the packing in a non-separable state. Therefore, in the packing molding process, a step such as insert molding of one of the packing holders into a mold is not required, and a conventional molding method using a suitable mold can be employed. Therefore, the above-described configuration increases the design freedom of the packing and simplifies the manufacturing process.

[0115] In particular, with the above configuration, the packing may have a portion that is not in close contact with the first packing holder or the second packing holder. Therefore, a sealed air layer can be easily formed between the packing and the first packing holder or the second packing holder, regardless of whether the lid opens or closes the opening. This air layer allows the lid to reduce heat transfer between the inside and outside of the container body, improving the heat retention or cold retention function inside the container body.

[0116] The packing according to each of the above-described embodiments may have a protrusion that fits tightly against the opening, and the length of the protrusion that protrudes from the periphery may be 6 mm or less. Also, the lid may include a shielding portion different from the packing within 12 mm from the tip of the protrusion.

[0117] With the above configuration, the gripping margin of the protrusion is reduced, or the shielding portion that prevents gripping of the protrusion is located near the protrusion, making the protrusion difficult to grip with the fingers of the container user. Furthermore, the protrusion more strongly reminds the container user that the packing is not intended to be removed from the lid by gripping the protrusion. Therefore, the above configuration reduces the possibility of damaging the packing when attempting to forcibly remove it from the lid. Furthermore, when the shielding portion includes at least one of the first packing holder and the second packing holder, it is not necessary to design a member such as an outer shell to extend near the protrusion, simplifying the structure of the lid.

[0118] The joining of the first packing holder and the second packing holder is achieved by the joining process shown in the first embodiment or each of the modifications of the first embodiment. The joining of the first packing holder and the second packing holder may be performed by appropriately adopting a suitable method depending on, for example, the shapes of each part of the container, including the packing, the first packing holder, and the second packing holder. By adopting the above joining process, a process such as insert molding is not required to form the packing, and the packing can be formed using various molding methods, such as molding using a suitable mold. Therefore, the above configuration increases the design freedom of the packing and simplifies the packing molding process.

[0119] In each of the above-described embodiments, the exposed surface area of ​​the packing 20, which is held inseparably by each packing holder, may be 50% or less of the total surface area of ​​the packing 20. With the above-described configuration, the exposed area of ​​the packing inside the lid is sufficiently reduced, and contamination of the packing due to adhesion of dirt and the like to the packing can be reduced. As described above, the packings according to each of the above-described embodiments have a high degree of design freedom, making it easier to design a reduced exposed area of ​​the packing, including, for example, reducing the portion of the packing exposed from each packing holder.

[0120] In each of the above-described embodiments, the restraint of the packing by the first packing holder and the second packing holder may be achieved by setting the dimensions of the retaining portion of the packing to prevent it from slipping out from between the first packing holder and the second packing holder. With the above configuration, the specific shape of the retaining portion is not limited as long as the dimensions of the retaining portion satisfy the above. This increases the degree of freedom in the shape of the retaining portion, making it easier to design, for example, to form the above-described air layer between the packing, the first packing holder, and the second packing holder.

[0121] In each of the above-described embodiments, the packing may include a first contact portion that contacts a first opening periphery of the container body when the lid closes the opening, and a second contact portion that contacts a second opening periphery different from the first opening periphery. This configuration increases the area where the packing and the container body are in close contact, thereby improving the sealing performance of the packing between the container body and the lid. As described above, the packings according to the above-described embodiments have a high degree of freedom in design, making it easier to design the first and second contact portions.

[0122] The present disclosure is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining different technical means disclosed in the respective embodiments are also included in the technical scope of the present disclosure.
