Modes for Carrying Out the Invention

[0011] First, with reference to FIGS. 1 to 6, the configuration of a beverage container 1 according to an embodiment of the present invention will be described.

[0012] As shown in FIGS. 1 and 2, the beverage container 1 includes a lower container 10, an upper container 20 connected to the lower container 10, a cup member 30 connected to the upper container 20, an inner container 40 housed in the lower container 10, a drinking mouth member 50 attached to the upper container 20, a nipple member 60 to be placed in an infant's mouth, a straw member 70, and a lid member 80 connected to the lower container 10.

[0013] First, the lower container 10 will be described. As shown in FIG. 3, the lower container 10 is a bottomed cylindrical container with an open top 11, and is a metal container such as stainless steel having a heat insulation structure of a double wall 12.

[0014] The double wall 12 consists of an inner wall 12a and an outer wall 12b, and the space between the inner wall 12a and the outer wall 12b is a vacuum heat insulation space 13. An annular protrusion 14 protruding radially inward is formed on the inner circumference of the lower container 10. The inner container 40 is releasably engaged with the protrusion 14.

[0015] A connection portion 15 to which the upper container 20 or the lid member 80 is connected is formed at the upper top 11 of the double wall 12, and a female screw 16 that is screwed with the upper container 20 or the lid member 80 is provided on the inner circumference of the connection portion 15. Note that the connection portion 15 may be formed as a double wall consisting of the inner wall 12a and the outer wall 12b.

[0016] Next, the upper container 20 will be described. As shown in FIG. 2, the upper container 20 is a cylindrical container with openings at both the upper end 21 and the lower end 22. The upper container 20 has an annular exposed portion 23 that is exposed from both the lower container 10 and the cup member 30 between the lower container 10 and the cup member 30. Since the upper container 20 is a container made of a polymer material such as transparent or translucent plastic or glass, the beverage in the beverage container 1 is visible through the exposed portion 23. Note that the polymer material includes elastomer made of rubber such as silicone rubber, plastic, and other materials mainly composed of polymers.

[0017] As shown in FIG. 1, on the exposed portion 23, there is provided a scale 24 composed of a plurality of scale lines 24a to 24g for checking the amount of the beverage in the beverage container 1. The scale lines 24a to 24g are each drawn as a straight line obliquely with respect to the vertical direction and consist of a pair of opposing lines. A numerical value "100" indicating 100 cc is printed between the scale lines 24b. Similarly, numerical values for checking the amount are also printed between the scale lines 24d and between the scale lines 24f. As will be described later, the scale lines 24a to 24g are scale lines corresponding to the liquid level of the beverage in the horizontal posture (see FIG. 7).

[0018] As shown in FIG. 2, the upper container 20 has an exposed portion 23, a lower connecting portion 25 connected to the lower container 10, and an upper connecting portion 26 to which the cup member 30 is connected and the drinking mouth member 50 is attached. The lower connecting portion 25 is formed below the exposed portion 23, and the upper connecting portion 26 is formed above the exposed portion 23. On the outer periphery of the lower connecting portion 25, an external thread 27 connected to the lower container 10 is provided.

[0019] The upper connecting portion 26 has a large-diameter portion 26a having substantially the same outer diameter as the lower connecting portion 25, and a small-diameter portion 26b having an outer diameter smaller than that of the large-diameter portion 26a. On the outer periphery of the large-diameter portion 26a, an external thread 28 to which the cup member 30 is connected is provided. On the outer periphery of the small-diameter portion 26b, an attachment portion 29 to which the drinking mouth member 50 is attached is provided. The attachment portion 29 is, for example, an annular convex portion for locking the drinking mouth member 50 by contact friction with the inner periphery of the drinking mouth member 50.

[0020] Next, the cup member 30 will be described. As shown in FIGS. 1, 2, and 6, the cup member 30 has a cup portion 31 that covers one end of the upper container 20, and a handle 32 through which a finger or a carabiner passes and that protrudes radially outward from the lower container 10. On the cup portion 31, irregularities 33 for improving the grip on the outer periphery are provided. The handle 32 may be made of a non-deformable material such as plastic, or may be made of an elastically deformable thermoplastic elastomer (rubber). By adopting a rubber material, the texture when passing a finger through the hole 34 can be improved.

[0021] The cup member 30 is a member that serves as a cup for pouring and drinking beverages, and can stand on its own with a flat top 35 as the bottom. Inside the opening end 36 of the cup member 30, a female screw 37 (see FIG. 6) is provided and screwed onto the male screw 28 of the upper container 20.

[0022] Next, the inner container 40 will be described. As shown in FIGS. 2 and 4, the inner container 40 is a bottomed cylindrical container with an open top 41, and is made of a polymer material capable of elastic deformation. In the present embodiment, the inner container 40 is made of silicone rubber or thermoplastic elastomer. The inner container 40 has a top 41 that abuts against the lower end 22 of the upper container 20, an engaging portion 42 that engages with the protruding portion 14 of the lower container 10, and an inner container body 43 that houses the beverage.

[0023] As shown in FIG. 4, the engaging portion 42 is provided on the outer periphery of the inner container 40 so as to be engageable with the protruding portion 14 of the lower container 10. The outer diameter W1 of the engaging portion 42 is formed smaller than the outer diameter W2 of the top 41 and the outer diameter W3 on the upper side of the inner container body 43. That is, the engaging portion 42 is formed to be recessed from the outer peripheral surfaces of both the top 41 and the inner container body 43.

[0024] The outer diameter of the inner container body 43 gradually decreases toward the bottom, and the outer diameter W4 on the lower side of the inner container body 43 is formed smaller than the outer diameter W3 on the upper side of the inner container body 43. Thereby, when the inner container body 43 passes through the protruding portion 14, the resistance due to contact with the protruding portion 14 is smaller when the lower side of the inner container body 43 passes through than when the upper side of the inner container body 43 passes through. For this reason, it is easy to accommodate the inner container 40 in the lower container 10.

[0025] When removing the inner container 40 from the lower container 10, insert a fingertip into the gap 17 formed between the inner circumference of the connecting portion 15 of the lower container 10 and the outer circumference of the top portion 41 of the inner container 40, and elastically deform the inner container 40 inward to remove it. Also, by pinching a part of the top portion 41 with a fingertip and pulling it upward, the inner container 40 can be elastically deformed, and the inner container 40 can be removed from the lower container 10. Further, by applying a fingertip to the inclined portion 44 formed on the back side of the engaging portion 42 and pulling it upward, the inner container 40 can be removed from the lower container 10 while being elastically deformed. In this way, when the inner container 40 is elastically deformed, the engagement between the engaging portion 42 and the protruding portion 14 is released.

[0026] In a state where the engaging portion 42 is engaged with the protruding portion 14, the inner container 40 is supported by the protruding portion 14, and a heat insulating space 18 by air is formed between the inner wall 12a of the lower container 10 and the inner container body 43 of the inner container 40. Therefore, the beverage inside the inner container 40 is kept warm or cold by the heat insulating spaces 13 and 18, and the inner container 40 housed in the lower container 10 has a higher heat retention and cold retention effect than a beverage container having only a simple vacuum double structure. Note that, in order for the inner container 40 not to be greatly deformed in shape by the weight of the beverage, for example, a support portion (not shown) that contacts the bottom surface of the inner wall 12a may be formed outside the bottom surface of the inner container body 43.

[0027] Next, the drinking mouth member 50, the nipple member 60, and the straw member 70 will be described. As shown in FIGS. 2 and 6, the drinking mouth member 50 is a cylindrical member having openings at the upper end 51 and the lower end 52, respectively. The user can directly drink the beverage by attaching the lips to the opening at the upper end 51, and can also pour the beverage from the opening at the upper end 51 into the cup portion 31.

[0028] In addition, a nipple member 60 or a straw member 70 can be attached to the drinking mouth member 50. As shown in FIG. 6, when attaching the nipple member 60 to the drinking mouth member 50, the nipple member 60 is inserted through the opening at the lower end 52 of the drinking mouth member 50 and protrudes from the opening at the upper end 51 to be attached to the drinking mouth member 50. At this time, the nipple member 60 is engaged with the engaging portion 54 formed inside the drinking mouth member 50 by the flange-shaped engaging portion 61 and is sandwiched between the drinking mouth member 50 and the upper container 20. The nipple member 60 attached to the drinking mouth member 50 is accommodated inside the cup member 30.

[0029] When attaching the straw member 70 (see FIG. 2) to the drinking mouth member 50, the straw member 70 is inserted through the opening at the upper end 51 of the drinking mouth member 50. The straw member 70 attached to the drinking mouth member 50 is also accommodated inside the cup member 30.

[0030] In this way, the beverage container 1 can be used in different modes, such as attaching the nipple member 60 to the drinking mouth member 50, attaching the straw member 70 to the drinking mouth member 50, using only the drinking mouth member 50, and using the cup member 30. Therefore, the beverage container 1 can be used by infants to adults. Specifically, infants can be made to drink breast milk or formula milk placed in the beverage container 1. Also, children can be made to drink milk or sports drinks placed in the beverage container 1. Moreover, various beverages can be placed in the beverage container 1 for adults. The beverage container 1 can keep various beverages warm or cold and be carried around without restrictions on use, such as only during infancy or only for children who have passed the lactation period, during the process of a child's growth from birth. Among them, a baby bottle becomes unusable after a child passes the infancy period, but the beverage container 1 can be used from infants to adults regardless of the season, so it can be used over a long period (that is, for a long life).

[0031] Next, the lid member 80 will be described. As shown in FIG. 2, the lid member 80 is a member connected to the lower container 10. The lid member 80 has a top plate 81 that seals the lower container 10 and the inner container 40, and a connecting portion 82 connected to the lower container 10. An external thread 83 connected to the lower container 10 is provided on the outer periphery of the connecting portion 82. The connecting portion 82 may be either hollow or solid. By bringing the lower end of the connecting portion 82 into close contact with the upper end surface 41a (see FIG. 4) of the top 41 of the inner container 40, the space between the lid member 80 and the inner container 40 is sealed.

[0032] When the lid member 80 is used, the height of the beverage container 1 can be suppressed compared to the case where the upper container 20 and the cup member 30 are used with respect to the lower container 10. In addition, since the surface area of the non-insulated structure of the entire beverage container 1 is reduced, the heat insulation of the beverage is enhanced.

[0033] Next, with reference to FIGS. 5 and 6, the sealing structure between the members will be described.

[0034] First, the sealing between the upper container 20 and the inner container 40 will be described. As shown in FIG. 5, the upper container 20 is attached to the lower container 10 by screwing the external thread 27 of the upper container 20 and the internal thread 16 of the lower container 10. When the upper container 20 is attached to the lower container 10, the lower end surface 22a of the upper container 20 abuts against the upper end surface 41a of the inner container 40, and the lower end surface 22a and the upper end surface 41a are brought into close contact and sealed by the axial force of screwing the upper container 20 into the lower container 10.

[0035] That is, when the upper container 20 is attached to the lower container 10, the internal space of the upper container 20 and the inner container 40 accommodated in the lower container 10 becomes integrated to form a space for accommodating the beverage. Then, the lower end surface 22a of the upper container 20 and the upper end surface 41a of the inner container 40 abut and are brought into close contact and sealed. In this way, the inner container 40 (upper end surface 41a) made of a polymer material also serves as a packing.

[0036] Next, the sealing between the lower container 10 and the inner container 40 will be described. As shown in FIG. 5, when the upper container 20 is attached to the lower container 10, the upper horizontal surface 45 formed at the engaging portion 42 of the inner container 40 is pressed against the protruding portion 14 of the lower container 10 by the force with which the upper container 20 presses the inner container 40 downward. As a result, the upper horizontal surface 45 and the protruding portion 14 are in close contact and sealed.

[0037] Next, the sealing by the drinking mouth member 50 will be described. As shown in FIG. 6, when the inner circumference of the connecting portion 53 of the drinking mouth member 50 abuts on the attaching portion 29 of the upper container 20, the space between the drinking mouth member 50 and the upper container 20 is sealed.

[0038] Further, when the nipple member 60 is sandwiched between the drinking mouth member 50 and the upper container 20, the flange-shaped engaging portion 61 of the nipple member 60 abuts on and is in close contact with the upper end 21 of the upper container 20 and is sealed. As a result, the internal spaces of the upper container 20 and the nipple member 60 become integrated.

[0039] Also, as shown in FIG. 6, on the inner circumference of the cup member 30, a sealing portion 38 that matches the shape of the outer peripheral portion 51a of the upper end 51 of the drinking mouth member 50 is formed in an annular shape so as to correspond to the outer peripheral portion 51a. When the cup member 30 is screwed to the upper container 20 to the lower limit position, the outer peripheral portion 51a and the sealing portion 38 abut on and are in close contact with each other and sealed, preventing the beverage from leaking to the outside.

[0040] The drinking mouth member 50 is formed of an elastically deformable material such as rubber, for example, and when the outer peripheral portion 51a and the sealing portion 38 abut on each other, the outer peripheral portion 51a deforms so as to widely follow the shape of the sealing portion 38 and comes into closer contact. On the other hand, the engaging portion 54 formed inside the drinking mouth member 50 is formed of a non-deformable material such as plastic, reliably compresses the engaging portion 61 of the nipple member 60, and enhances the adhesion with the nipple member 60. Thus, the drinking mouth member 50 may have a configuration in which an elastically deformable part (not shown) and a non-deformable part (not shown) are combined, or may be configured by a single member.

[0041] Here, when the straw member 70 is attached to the drinking mouth member 50, or when only the drinking mouth member 50 is attached to the upper container 20, the beverage can move from the opening of the drinking mouth member 50 into the inside of the cup member 30. However, as described above, since the space between the outer peripheral portion 51a and the seal portion 38 is sealed, leakage of the beverage downward from the seal portion 38 is prevented.

[0042] Further, when the cup member 30 is screwed to the lower limit position with respect to the upper container 20, the tip portion 63 of the nipple member 60 abuts against and seals the central portion 39 at the bottom inside the cup portion 31. For this reason, leakage of the beverage from the nipple member 60 is prevented.

[0043] Note that the drinking mouth member 50 may be integrally formed with the upper container 20 instead of being separate. In this case, the upper end 21 of the upper container 20 extends so as to abut against the seal portion 38 of the cup member 30, and the seal portion 38 is sealed by the upper container 20.

[0044] Incidentally, the upper container 20 and the inner container 40 are containers that come into contact with the beverage, and the lower container 10 is a container that does not come into contact with the beverage.

[0045] Therefore, even if a beverage containing salt such as artificial milk, milk beverage, sports drink, soup, or oatmeal is placed in the beverage container 1, since the lower container 10 does not come into contact with the beverage, the lower container 10 is not corroded by the salt contained in the beverage. On the other hand, members other than the lower container 10, such as the upper container 20, the cup member 30, and the inner container 40, are made of a polymer material that is not corroded by the salt contained in the beverage, so that various beverages can be accommodated.

[0046] Also, when the container is made of metal, in the case of disinfection by boiling, the double wall of the vacuum structure may be damaged, and in the case of disinfection with a chemical solution, the metal may be corroded by the chemical solution. Furthermore, since a metal material generates sparks when placed in a microwave oven and irradiated with microwaves, which may cause a fire, a disinfection method using a microwave oven cannot be applied to a metal container.

[0047] However, since the lower container 10 made of metal does not come into contact with the beverage, disinfection is not required. On the other hand, members other than the lower container 10 that come into contact with the beverage are made of a polymer material that can be disinfected by any of boiling, chemical solution, or microwave oven, so disinfection can be easily performed.

[0048] That is, the beverage container 1 has a heat insulation structure of the double wall 12 under the usefulness of the metal material that is excellent in workability and durability, and overcomes the difficulties of the metal material, namely, "possibility of corrosion" and "difficulty in easily performing disinfection", by adopting a structure in which the lower container 10 does not come into contact with the beverage. As a result, it is possible to put beverages containing salt or beverages that may spoil in the beverage container 1, and the beverage can be carried while maintaining a high heat retention and cold retention effect. Furthermore, since the beverage container 1 can accommodate multiple drinking methods through the drinking mouth member 50, it can be used for a long time.

[0049] In addition, when the beverage spoils, gas is generated and an expansion pressure is applied from the inside, leading to container breakage or accidents. However, since the inner container 40 can be turned inside out and washed, it is easy to clean and there is no residue due to washing residue. As a result, in the beverage container 1, the risk of the next beverage put in spoiling is reduced, so the risk of container breakage or accidents is reduced.

[0050] Next, with reference to FIG. 7, the scale 24 and the scale lines 24a to 24g provided on the exposed portion 23 will be described.

[0051] As shown in FIG. 7, the beverage container 1 can be placed with the lower container 10 and the handle 32 to take a stable stationary state. The stationary state is a posture for checking the amount of the beverage in the beverage container 1, and since the beverage container 1 is placed obliquely sideways, it is called a horizontal posture. The horizontal posture includes postures in which the beverage container 1 is placed obliquely or horizontally, and does not include the posture of standing the beverage container 1 upright.

[0052] When the beverage container 1 is in the horizontal position, the grounding portion 10a of the lower container 10 and the grounding portion 32a of the handle 32 are in contact with the installation ground 100. Since the grounding portion 32a has a predetermined width with respect to the installation ground 100, the horizontal position of the beverage container 1 is stabilized. Thus, the handle 32 is also used as a part for the beverage container 1 to take the horizontal position. Note that, regardless of the handle 32, a part for the beverage container 1 to take the horizontal position may be provided on the outer periphery of the lower container 10 or the cup member 30. Also, a member different from the handle 32 may be provided on the beverage container 1 to make the beverage container 1 take the horizontal position.

[0053] Also, in FIG. 7, the liquid levels S1 to S7 of beverages when different volumes of beverages are put into the beverage container 1 with the nipple member 60 attached are shown. Hereinafter, the liquid levels S1 to S7 will be described in correspondence with the scale lines 24a to 24g shown in FIG. 1.

[0054] The liquid level S1 shown in FIG. 7 is the liquid level when 50 cc of beverage is put in, and corresponds to the scale line 24a. The liquid level S2 is the liquid level when 100 cc of beverage is put in, and corresponds to the scale line 24b. The liquid level S3 is the liquid level when 150 cc of beverage is put in, and corresponds to the scale line 24c. The liquid level S4 is the liquid level when 200 cc of beverage is put in, and corresponds to the scale line 24d. The liquid level S5 is the liquid level when 250 cc of beverage is put in, and corresponds to the scale line 24e. The liquid level S6 is the liquid level when 300 cc of beverage is put in, and corresponds to the scale line 24f. The liquid level S7 is the liquid level when 350 cc of beverage is put in, and corresponds to the scale line 24g.

[0055] Thus, the scale lines 24a to 24g are provided corresponding to the liquid level of the beverage in the state where the beverage container 1 is in the horizontal position. Hereinafter, the reason why the scale 24 is provided on the exposed portion 23 will be described.

[0056] Referring to FIG. 1 or FIG. 6, since the metal lower container 10 is an opaque member, when the beverage container 1 is erected, if the liquid level of the beverage does not exceed the height of the lower container 10, the liquid level of the beverage cannot be visually recognized from the side through the exposed portion 23. Also, when the liquid level of the beverage is at the height of the cup member 30, if the cup member 30 is an opaque member, the liquid level of the beverage cannot be visually recognized from the side through the exposed portion 23.

[0057] On the other hand, as shown in FIG. 7, when the beverage container 1 is placed stationary in a horizontal position, regardless of the amount of beverage, the liquid level of the beverage can be visually recognized through the exposed portion 23. Therefore, the exposed portion 23 is provided with a scale 24 so that the user can place the beverage container 1 in a horizontal position and confirm the amount of beverage using the scale 24.

[0058] In this way, the beverage container 1 has both high heat insulation by the metal lower container 10 that is excellent in workability and durability, and a structure for confirming the amount of beverage by the upper container 20 made of a transparent or translucent polymer material.

[0059] In addition, when the user visually recognizes the beverage through the exposed portion 23, considering that the height of the liquid level appears refracted by the exposed portion 23, the scale lines 24a to 24g are provided on the inner periphery of the exposed portion 23.

[0060] Also, when the nipple member 60 is not attached, the beverage can move from the opening of the drinking mouth member 50 to the inside of the cup member 30. For this reason, even when the same volume of beverage is filled, the height of the liquid level of the beverage when the nipple member 60 is not attached is lower than the liquid levels S3 to S7 when the nipple member 60 is attached, respectively. For this reason, a scale line when the nipple member 60 is attached may be provided on one side of the exposed portion 23, and a scale line when the nipple member 60 is not attached may be provided on the other side of the exposed portion 23. At this time, an icon representing the nipple member 60 may be displayed together with the scale line on one side of the exposed portion 23, and an icon representing the drinking mouth member 50 may be displayed together with the scale line on the other side of the exposed portion 23.

[0061] Further, the scale lines 24a to 24g are not limited to straight scale lines, and may be broken lines or wavy lines. Also, when a non-transparent beverage is contained, the scale lines may be transparent or semi-transparent so that the scale lines can be visually recognized depending on the color of the beverage. Further, instead of the scale lines, for example, scales made of dots or scales consisting only of numerical values may be used.

[0062] Hereinafter, the configurations, operations, and effects of the embodiments of the present invention will be collectively described.

[0063] The beverage container 1 has a bottomed cylindrical lower container 10 having a double wall 12 for a heat insulating space and an open top 11, and a cylindrical upper container 20 having an open upper end 21 and a lower end 22, and the lower end 22 is connected to the top 11 of the lower container 10. The lower container 10 is made of metal, and the upper container 20 is made of a transparent or semi-transparent polymer material or glass.

[0064] According to this configuration, the beverage container 1 has a heat insulating structure with a double wall 12 in the metal lower container 10 that is excellent in workability and durability, and since the upper container 20 is transparent or semi-transparent, the user can visually recognize the amount of the beverage through the upper container 20.

[0065] The upper container 20 is provided with a scale 24 for confirming the amount of the beverage in the beverage container 1.

[0066] According to this configuration, when visually recognizing the amount of the beverage through the upper container 20, the user can confirm the amount of the beverage by the scale 24.

[0067] The beverage container 1 further has a cup member 30 connected to the upper end 21 of the upper container 20. The cup member 30 has a grounding portion 32a grounded to the installation ground 100 in order to take a horizontal posture for confirming the amount of the beverage in the beverage container 1. The scale 24 is scale lines 24a to 24g corresponding to the liquid level of the beverage when the beverage container 1 is in a horizontal posture.

[0068] According to this configuration, by causing the grounding portion 32a to hold the beverage container 1 in a horizontal posture, the user can visually recognize the liquid level of the beverage through the upper container 20 regardless of the amount of the beverage. Then, the user can confirm the amount of the beverage by the scale lines 24a to 24g corresponding to the liquid level of the beverage in the horizontal posture provided on the upper container 20.

[0069] Further, the beverage container 1 has the following configuration, operation, and effect.

[0070] A bottomed cylindrical lower container 10 having a double wall 12 for a heat insulating space and an open top 11, a bottomed cylindrical inner container 40 housed in the lower container 10 and detachable from the lower container 10 with an open top 41, and a cylindrical upper container 20 having an open upper end 21 and an open lower end 22, the lower end 22 being connected to the lower container 10 and abutting against the top 41 of the inner container 40. The upper container 20 is made of a polymer material or glass, and the inner container 40 is made of a polymer material.

[0071] According to this configuration, since the inner container 40 and the upper container 20 in contact with the beverage are made of a polymer material (or glass), they can be disinfected with a chemical solution or the like. The lower container 10 not in contact with the beverage has a heat insulating space due to the double wall 12, resulting in high heat insulation. Therefore, the beverage container 1 enables the inner container 40 and the upper container 20 to be easily disinfected, and the disinfection of the lower container 10 is unnecessary. Further, since the inner container 40 and the upper container 20 of the beverage container 1 are made of a polymer material (or glass) that has no possibility of corrosion compared to a metal material, a beverage containing salt can be contained.

[0072] The lower container 10 has an annular protruding portion 14 protruding in the radial direction, and the inner container 40 has an engaging portion 42 formed on the outer periphery and engaged with the protruding portion 14, and the engagement with the protruding portion 14 is released by elastic deformation of the inner container 40.

[0073] According to this configuration, since the engagement between the inner container 40 and the protruding portion 14 is released by elastic deformation, the user can apply force to the inner container 40 with a fingertip to release the engagement with the protruding portion 14, and it is easy to attach and detach the inner container 40 from the lower container 10.

[0074] An insulating space 18 by air is provided between the lower container 10 and the inner container 40.

[0075] According to this configuration, in addition to the insulating space 13 formed by the internal space of the double wall 12 of the lower container 10, an insulating space 18 is provided between the lower container 10 and the inner container 40, so that the heat retention and cold retention effects of the beverage in the inner container 40 are high.

[0076] The upper container 20 is pressed against the inner container 40 by the axial force connecting the upper container 20 to the lower container 10, so that the space between the upper container 20 and the inner container 40 is sealed.

[0077] According to this configuration, a packing as a separate member is not required between the upper container 20 and the inner container 40, and the structure of the beverage container 1 can be simplified.

[0078] The beverage container 1 further has a cup member 30 connected to the upper end 21 of the upper container 20, and an annular seal portion 38 that contacts the drinking mouth member 50 is provided on the inner periphery of the cup member 30.

[0079] According to this configuration, the seal portion 38 provided on the inner periphery of the cup member 30 seals the cup member 30 and the drinking mouth member 50, so that a packing as a separate member is not required for the cup member 30. Therefore, the structure of the beverage container 1 can be simplified.

[0080] A straw member 70 or a nipple member 60 for a baby to hold in the mouth can be attached to the drinking mouth member 50.

[0081] According to this configuration, when the target for drinking the beverage is a baby, the nipple member 60 can be attached to the drinking mouth member 50, and when the target for drinking the beverage is a child, the straw member 70 can be attached to the drinking mouth member 50. Therefore, the beverage container 1 can be used even when the target for drinking the beverage grows from a baby to a child, and the beverage container 1 can be used for a long time from the birth of the child.

[0082] At the top 11 of the lower container 10, instead of the upper container 20, a lid member 80 that closes the opening of the lower container 10 can be connected.

[0083] According to this configuration, when the lid member 80 is connected to the lower container 10, the height of the beverage container 1 can be suppressed. Also, since the ratio of the non-insulated space is smaller than when using the upper container 20, the heat insulation of the beverage is improved.

[0084] As described above, the embodiments of the present invention have been explained. However, the above embodiments merely show a part of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above embodiments.

[0085] For example, each container and member other than the lower container 10 may also have a double wall for a heat insulation structure, and the top plate 81 of the cup member 30 and the lid member 80 may also have a double wall.
