[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-209217 Summary of the Invention [Problem to be solved by the invention]

[0005] The portable beverage container disclosed in Patent Document 1 has a stainless steel container that comes into direct contact with the beverage, so if a beverage containing salt is placed inside, the stainless steel container may be corroded by the salt.

[0006] Furthermore, after pouring a potentially spoiled beverage into a container, the inside of the container needs to be disinfected. However, the commonly known disinfection methods of boiling, disinfection in a microwave oven, and disinfection with chemical solutions are all unsuitable for the stainless steel portable beverage container disclosed in Patent Document 1.

[0007] Boiling can damage the vacuum structure of the container due to deformation caused by heat. Disinfection by heating the container in a microwave with water is not suitable because the container is made of metal. Disinfection with a chemical solution containing sodium hypochlorite can corrode stainless steel containers.

[Figure 7] 1 is a cross-sectional view of a beverage container placed horizontally according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0012] First, the configuration of a beverage container 1 according to an embodiment of the present invention will be described with reference to FIGS.

[0013] As shown in Figures 1 and 2, the beverage container 1 comprises 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 spout member 50 attached to the upper container 20, a nipple member 60 to be placed in the mouth of an infant, a straw member 70, and a lid member 80 connected to the lower container 10.

[0014] First, we will explain the lower container 10. As shown in Fig. 3, the lower container 10 is a cylindrical container with a bottom and an open top 11, and is made of a metal such as stainless steel having a heat insulating structure with double walls 12.

[0015] 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 forms a vacuum insulating space 13. An annular protrusion 14 that protrudes radially inward is formed on the inner periphery of the lower container 10. The inner container 40 is releasably engaged with the protrusion 14.

[0016] A connecting portion 15 to which the upper container 20 or the lid member 80 is connected is formed at the top 11 of the upper side of the double wall 12, and a female thread 16 is provided on the inner periphery of the connecting portion 15 to be screwed into the upper container 20 or the lid member 80. The connecting portion 15 may be formed as a double wall consisting of an inner wall 12a and an outer wall 12b.

[0017] Next, the upper container 20 will be described. As shown in FIG. 2, the upper container 20 is a cylindrical container with an upper end 21 and a lower end 22 that are both open. The upper container 20 has an annular exposed portion 23 between the lower container 10 and the cup member 30, which is exposed from both the lower container 10 and the cup member 30. The upper container 20 is made of a polymeric material such as transparent or translucent plastic, or glass, so that the beverage in the beverage container 1 can be seen through the exposed portion 23. Note that the polymeric material includes elastomers containing rubber such as silicone rubber, plastics, and other materials whose main component is a polymer.

[0018] As shown in FIG. 1, the exposed portion 23 is provided with a scale 24 consisting of multiple scale lines 24a-24g for checking the amount of beverage in the beverage container 1. Each of the scale lines 24a-24g is a pair of opposing lines drawn diagonally with respect to the vertical. The number "100" indicating 100 cc is marked between the scale lines 24b. Similarly, numbers for checking the amount are also marked between the scale lines 24d and between the scale lines 24f. As will be described later, the scale lines 24a-24g correspond to the liquid level of the beverage when the container is placed horizontally (see FIG. 7).

[0019] 2, the upper container 20 has an exposed portion 23, a lower connection portion 25 connected to the lower container 10, and an upper connection portion 26 to which the cup member 30 is connected and to which the drinking spout member 50 is attached. The lower connection portion 25 is formed below the exposed portion 23, and the upper connection portion 26 is formed above the exposed portion 23. A male thread 27 connected to the lower container 10 is provided on the outer periphery of the lower connection portion 25.

[0020] The upper connecting part 26 has a large diameter part 26a that has approximately the same outer diameter as the lower connecting part 25, and a small diameter part 26b that has a smaller outer diameter than the large diameter part 26a. A male thread 28 to which the cup member 30 is connected is provided on the outer periphery of the large diameter part 26a. An attachment part 29 to which the spout member 50 is attached is provided on the outer periphery of the small diameter part 26b. The attachment part 29 is, for example, an annular protrusion that locks the spout member 50 in place by contact friction with the inner periphery of the spout member 50.

[0021] Next, the cup member 30 will be described. As shown in Figures 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 that protrudes radially outward from the lower container 10 and has a hole 34 through which a finger or carabiner can be passed. The cup portion 31 is provided with projections and recesses 33 to improve grip on the outer periphery. 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). Using rubber can improve the texture when passing a finger through the hole 34.

[0022] The cup member 30 is a member that serves as a cup into which a beverage is poured and drunk, and can stand on its own with a flat top portion 35 as the bottom. A female screw 37 (see FIG. 6) is provided on the inside of an open end 36 of the cup member 30, and is threadedly engaged with the male screw 28 of the upper container 20.

[0023] Next, the inner container 40 will be described. As shown in Figures 2 and 4, the inner container 40 is a cylindrical container with a bottom and an open top 41, and is made of a polymeric material that is elastically deformable. In this embodiment, the inner container 40 is made of silicone rubber or a thermoplastic elastomer. The inner container 40 has the 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 contains a beverage.

[0024] 4, the engaging portion 42 is provided on the outer periphery of the inner container 40 so as to be able to engage with the protruding portion 14 of the lower container 10. The outer diameter W1 of the engaging portion 42 is smaller than the outer diameter W2 of the top portion 41 and the outer diameter W3 of the upper side of the inner container body 43. In other words, the engaging portion 42 is recessed from the outer periphery of both the top portion 41 and the inner container body 43.

[0025] The outer diameter of the inner container body 43 gradually decreases toward the bottom, and the outer diameter W4 of the lower side of the inner container body 43 is smaller than the outer diameter W3 of the upper side of the inner container body 43. As a result, 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 than when the upper side of the inner container body 43 passes. This makes it easier to store the inner container 40 in the lower container 10.

[0026] When removing the inner container 40 from the lower container 10, the inner container 40 is elastically deformed inward by inserting a fingertip into the gap 17 formed between the inner periphery of the connecting portion 15 of the lower container 10 and the outer periphery of the top portion 41 of the inner container 40, thereby removing the inner container 40. The inner container 40 can also be elastically deformed and removed from the lower container 10 by grasping a part of the top portion 41 with the fingertip and pulling it upward. Furthermore, the inner container 40 can also be removed from the lower container 10 while elastically deforming by hooking a fingertip on the inclined portion 44 formed on the back side of the engaging portion 42 and pulling it upward. In this way, the inner container 40 elastically deforms, and the engaging portion 42 disengages from the protruding portion 14 as the inner container 40 elastically deforms.

[0027] When the engaging portion 42 is engaged with the protruding portion 14, the inner container 40 is supported by the protruding portion 14, and an air-insulated space 18 is formed between the inner wall 12a of the lower container 10 and the inner-container body 43 of the inner container 40. As a result, the beverage inside the inner container 40 is kept hot or cold by the insulating space 13 and the insulating space 18, and the inner container 40 housed in the lower container 10 has a higher heat / cold insulation effect than a beverage container that simply has a vacuum double structure. Note that the inner container 40 may have a support portion (not shown) formed on the outside of the bottom surface of the inner container body 43 that comes into contact with the bottom surface of the inner wall 12a to prevent the shape from being significantly deformed by the weight of the beverage.

[0028] Next, we will explain the drinking spout member 50, nipple member 60, and straw member 70. As shown in Figures 2 and 6, the drinking spout member 50 is a tubular member with openings at both an upper end 51 and a lower end 52. A user can drink a beverage directly by placing their lips over the opening at upper end 51, or can pour a beverage into the cup portion 31 through the opening at upper end 51.

[0029] A nipple component 60 or straw component 70 can also be attached to the drinking spout component 50. As shown in Figure 6, when attaching the nipple component 60 to the drinking spout component 50, the nipple component 60 is inserted through the opening at the lower end 52 of the drinking spout component 50 and protrudes from the opening at the upper end 51. At this time, the nipple component 60 is held between the drinking spout component 50 and the upper container 20, with the flange-shaped engaging portion 61 engaging with the engaging portion 54 formed on the inside of the drinking spout component 50. The nipple component 60 attached to the drinking spout component 50 is housed inside the cup component 30.

[0030] When attaching the straw member 70 (see FIG. 2) to the spout member 50, the straw member 70 is inserted through the opening at the upper end 51 of the spout member 50. The straw member 70 attached to the spout member 50 is also housed inside the cup member 30.

[0031] As described above, the beverage container 1 can be used in various ways, such as by attaching the nipple member 60 to the spout member 50, by attaching the straw member 70 to the spout member 50, by using the spout member 50 alone, or by using the cup member 30. Therefore, the beverage container 1 can be used by everyone from infants to adults. Specifically, infants can be given breast milk or prepared formula in the beverage container 1. Children can be given cow's milk or sports drinks in the beverage container 1. Various beverages can be stored in the beverage container 1 for adults. The beverage container 1 is not limited to use only in infancy or only for children who have passed the nursing stage, and can carry a variety of beverages hot or cold throughout a child's developmental process. While baby bottles are no longer used once a child passes infancy, the beverage container 1 can be used for a long period of time (i.e., has a long life) by everyone from infants to adults, regardless of the season.

[0032] Next, the lid member 80 will be described. As shown in Figure 2, the lid member 80 is a member that is 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 part 82 that is connected to the lower container 10. A male thread 83 that is connected to the lower container 10 is provided on the outer periphery of the connecting part 82. The connecting part 82 may be either hollow or solid. The lower end of the connecting part 82 is in close contact with the upper end surface 41a of the top part 41 of the inner container 40 (see Figure 4), thereby sealing the lid member 80 and the inner container 40.

[0033] By using the lid member 80, the height of the beverage container 1 can be reduced compared to when the upper container 20 and cup member 30 are used relative to the lower container 10, and the surface area of ​​the overall non-insulated structure of the beverage container 1 is reduced, thereby improving the insulation of the beverage.

[0034] Next, the sealing structure between the members will be described with reference to FIGS.

[0035] First, we will explain the sealing between the upper container 20 and the inner container 40. As shown in Figure 5, the upper container 20 is attached to the lower container 10 by threading the male thread 27 of the upper container 20 into the female 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 axial force applied when the upper container 20 is screwed into the lower container 10 causes the lower end surface 22a and the upper end surface 41a to tightly contact and form a seal.

[0036] In other words, when the upper container 20 is attached to the lower container 10, the internal spaces of the upper container 20 and the inner container 40 housed in the lower container 10 are integrated to form a space for housing a beverage. The lower end surface 22a of the upper container 20 and the upper end surface 41a of the inner container 40 come into contact with each other, forming a tight seal. In this way, the inner container 40 (upper end surface 41a) made of a polymeric material also serves as a packing.

[0037] Next, we will explain the sealing between the lower container 10 and the inner container 40. As shown in Figure 5, when the upper container 20 is attached to the lower container 10, the force with which the upper container 20 presses the inner container 40 downward presses the upper horizontal surface 45 formed on the engagement portion 42 of the inner container 40 against the protruding portion 14 of the lower container 10. This causes the upper horizontal surface 45 and the protruding portion 14 to come into close contact and form a seal.

[0038] Next, we will explain the sealing provided by the spout member 50. As shown in Figure 6, the inner periphery of the connection part 53 of the spout member 50 abuts against the attachment part 29 of the upper container 20, thereby sealing the space between the spout member 50 and the upper container 20.

[0039] Furthermore, when the nipple member 60 is sandwiched between the drinking spout member 50 and the upper container 20, the flange-shaped engaging portion 61 of the nipple member 60 comes into contact with the upper end 21 of the upper container 20, forming a tight seal. This unites the internal spaces of the upper container 20 and the nipple member 60.

[0040] 6, a ring-shaped seal portion 38 is formed on the inner periphery of the cup member 30 so as to correspond to the outer periphery 51a of the upper end 51 of the drinking spout member 50. When the cup member 30 is screwed onto the upper container 20 to its lowest position, the outer periphery 51a and the seal portion 38 come into contact with each other to form a tight seal, preventing the beverage from leaking outward.

[0041] The spout member 50 is made of an elastically deformable material such as rubber, and when the outer periphery 51a comes into contact with the seal member 38, the outer periphery 51a deforms to conform to the shape of the seal member 38 over a wide area, providing a tighter fit. The engaging portion 54 formed on the inside of the spout member 50 is made of a non-deformable material such as plastic, which reliably compresses the engaging portion 61 of the nipple member 60, enhancing the tightness of the fit with the nipple member 60. Thus, the spout member 50 may be constructed from a combination of an elastically deformable part (not shown) and a non-deformable part (not shown), or may be constructed from a single member.

[0042] Here, when the straw member 70 is attached to the spout member 50, or when only the spout member 50 is attached to the upper container 20, the beverage can move into the cup member 30 through the opening of the spout member 50. However, as described above, the gap between the outer circumferential portion 51a and the seal portion 38 is sealed, preventing the beverage from leaking downward from the seal portion 38.

[0043] Furthermore, when the cup member 30 is screwed onto the upper container 20 to the lowest position, the tip 63 of the nipple member 60 abuts and seals against the center part 39 of the inner bottom of the cup part 31. This prevents the beverage from leaking from the nipple member 60.

[0044] The drinking spout member 50 may be integral with the upper container 20 rather than being separate from it. In this case, the upper end 21 of the upper container 20 is extended 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.

[0045] The upper container 20 and the inner container 40 are containers that come into contact with the beverage, while the lower container 10 is a container that does not come into contact with the beverage.

[0046] Therefore, even if a beverage containing salt such as infant formula, milk drink, sports drink, soup, or porridge is poured into the beverage container 1, the lower container 10 does not come into contact with the beverage and is therefore not corroded by the salt contained in the beverage. On the other hand, the components other than the lower container 10, such as the upper container 20, cup member 30, and inner container 40, are made of polymeric materials that are not corroded by the salt contained in the beverage, so a variety of beverages can be stored therein.

[0047] Furthermore, if the container is made of metal, boiling the container may damage the vacuum-structured double wall, and chemical disinfection may corrode the metal. Furthermore, when metal materials are placed in a microwave oven and exposed to microwaves, sparks may occur, which can cause a fire, so metal containers cannot be disinfected using a microwave oven.

[0048] However, the metal lower container 10 does not need to be sterilized because it does not come into contact with the beverage. On the other hand, the components other than the lower container 10 that come into contact with the beverage are made of polymeric materials that can be sterilized by boiling, chemical solutions, or microwave ovens, so they can be easily sterilized.

[0049] In other words, beverage container 1 has the advantages of metal materials, such as their excellent workability and durability, and an insulated double-wall structure 12, eliminating the drawbacks of metal materials, such as the possibility of corrosion and the inability to easily disinfect, by designing the lower container 10 so that it does not come into contact with the beverage. This allows beverage container 1 to hold beverages that contain salt or that may spoil, and allows beverages to be carried with excellent heat and cold insulation. Furthermore, beverage container 1 can be used for a long time because it can be used in multiple ways via the drinking spout 50.

[0050] Furthermore, when a beverage spoils, gas is generated, causing expansion pressure from the inside, which can lead to damage to the container or an accident, but the inner container 40 can be turned upside down for easy cleaning, and no residue is left behind after washing. As a result, the risk of spoilage of the next beverage placed in the beverage container 1 is reduced, thereby reducing the risk of damage to the container or an accident.

[0051] Next, the scale 24 and the scale lines 24a to 24g provided on the exposed portion 23 will be described with reference to FIG.

[0052] As shown in Figure 7, the beverage container 1 can be placed in a stable, stationary state by connecting the lower container 10 and the handle 32. This stationary state is a position for checking the amount of beverage in the beverage container 1, and is called a horizontal position because the beverage container 1 is placed diagonally on its side. The horizontal position includes positions in which the beverage container 1 is placed diagonally and horizontally, but does not include positions in which the beverage container 1 is placed upright.

[0053] When the beverage container 1 is in a horizontal position, the ground contact portion 10a of the lower container 10 and the ground contact portion 32a of the handle 32 come into contact with the installation surface 100. The ground contact portion 32a has a predetermined width relative to the installation surface 100, so that the beverage container 1 is stable in a horizontal position. In this way, the handle 32 is also used as a part for allowing the beverage container 1 to assume a horizontal position. Note that, instead of the handle 32, a part for allowing the beverage container 1 to assume a horizontal position may be provided on the outer periphery of the lower container 10 or the cup member 30. Also, a member other than the handle 32 may be provided on the beverage container 1 to allow the beverage container 1 to assume a horizontal position.

[0054] 7 also shows liquid levels S1 to S7 of beverages of different volumes poured into a beverage container 1 equipped with a nipple member 60. Below, the liquid levels S1 to S7 will be explained in relation to the scale lines 24a to 24g shown in FIG.

[0055] The liquid level S1 shown in FIG. 7 is the liquid level when 50 cc of beverage is poured, and corresponds to the scale line 24a. The liquid level S2 is the liquid level when 100 cc of beverage is poured, and corresponds to the scale line 24b. The liquid level S3 is the liquid level when 150 cc of beverage is poured, and corresponds to the scale line 24c. The liquid level S4 is the liquid level when 200 cc of beverage is poured, and corresponds to the scale line 24d. The liquid level S5 is the liquid level when 250 cc of beverage is poured, and corresponds to the scale line 24e. The liquid level S6 is the liquid level when 300 cc of beverage is poured, and corresponds to the scale line 24f. The liquid level S7 is the liquid level when 350 cc of beverage is poured, and corresponds to the scale line 24g.

[0056] In this way, the scale lines 24a to 24g are provided corresponding to the liquid level of the beverage when the beverage container 1 is in a horizontal position. The reason why the scale 24 is provided on the exposed portion 23 will be explained below.

[0057] 1 or 6, since the metallic lower container 10 is an opaque member, when the beverage container 1 is held upright, the beverage level cannot be seen from the side through the exposed portion 23 unless the beverage level exceeds the height of the lower container 10. Also, even if the beverage level is at the height of the cup member 30, if the cup member 30 is an opaque member, the beverage level cannot be seen from the side through the exposed portion 23.

[0058] 7, when beverage container 1 is placed horizontally, the liquid level of the beverage can be seen through exposed portion 23 regardless of the amount of beverage. Therefore, scale 24 is provided on exposed portion 23 so that the user can place beverage container 1 horizontally and check the amount of beverage using scale 24.

[0059] In this way, the beverage container 1 has both high thermal insulation properties due to the lower container 10 made of metal, which is easy to process and durable, and a structure that allows the amount of beverage to be checked due to the upper container 20 made of a transparent or translucent polymeric material.

[0060] The scale lines 24a to 24g are provided on the inner circumference of the exposed portion 23, taking into consideration that the liquid level appears refracted by the exposed portion 23 when the user visually checks the beverage through the exposed portion 23.

[0061] Furthermore, when the nipple member 60 is not attached, the beverage can move from the opening of the spout member 50 to the inside of the cup member 30. Therefore, even when the same volume of beverage is poured, the liquid levels S3 to S7 of the beverage when the nipple member 60 is not attached will be lower than the liquid levels S3 to S7 when the nipple member 60 is attached. For this reason, a scale line for when the nipple member 60 is attached may be provided on one side of the exposed portion 23, and a scale line for when the nipple member 60 is not attached may be provided on the other side of the exposed portion 23. In this case, 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 spout member 50 may be displayed together with the scale line on the other side of the exposed portion 23.

[0062] Furthermore, the scale lines 24a to 24g are not limited to straight lines, but may be dashed or wavy. Furthermore, they may be transparent or semi-transparent so that when a non-transparent beverage is poured, the scale lines are visible due to the color of the beverage. Instead of scale lines, for example, scales using dots or scales with only numerical values ​​may be used.

[0063] The configuration, operation, and effects of the embodiment of the present invention will be described below.

[0064] The beverage container 1 comprises a cylindrical lower container 10 with a bottom and an open top 11, having a double wall 12 for an insulating space, and a cylindrical upper container 20 with an open top 21 and bottom 22, the bottom 22 of which 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 translucent polymeric material or glass.

[0065] According to this configuration, the beverage container 1 has a lower container 10 made of metal, which is easy to process and durable, and has an insulating structure with a double wall 12, and since the upper container 20 is transparent or translucent, the user can see the amount of beverage through the upper container 20.

[0066] The upper container 20 is provided with a scale 24 for checking the amount of beverage in the beverage container 1.

[0067] According to this configuration, when a user visually checks the amount of beverage through the upper container 20, the user can check the amount of beverage by looking at the scale 24.

[0068] It further has a cup member 30 connected to the upper end 21 of the upper container 20, and the cup member 30 has a grounding portion 32a that is grounded to the installation surface 100 so that the beverage container 1 can be placed horizontally to check the amount of beverage in the beverage container 1, and the scale 24 has scale lines 24a to 24g that correspond to the liquid level of the beverage when the beverage container 1 is placed horizontally.

[0069] With this configuration, by placing the beverage container 1 horizontally using the grounding portion 32a, the user can see the beverage level through the upper container 20, regardless of the amount of beverage. The user can then check the amount of beverage by looking at the scale lines 24a to 24g provided on the upper container 20, which correspond to the beverage level when the container is placed horizontally.

[0070] The beverage container 1 also has the following configuration, actions, and effects.

[0071] The container comprises a cylindrical lower container (10) with a bottom and an open top (11), having a double wall (12) for an insulated space, a cylindrical inner container (40) with a bottom and an open top (41) that is accommodated in the lower container (10) and is detachable from the lower container (10), and a cylindrical upper container (20) with an open upper end (21) and a lower end (22) that is connected to the lower container (10) and abuts against the top (41) of the inner container (40), the upper container (20) being made of a polymeric material or glass, and the inner container (40) being made of a polymeric material.

[0072] According to this configuration, the inner container 40 and upper container 20 that come into contact with the beverage are made of a polymeric material (or glass) and can be sterilized with chemicals, etc., while the lower container 10 that does not come into contact with the beverage has an insulating space formed by the double wall 12, providing high thermal insulation. Therefore, the inner container 40 and upper container 20 of the beverage container 1 can be easily sterilized, and sterilization of the lower container 10 is not necessary. Furthermore, since the inner container 40 and upper container 20 of the beverage container 1 are made of a polymeric material (or glass) that is less likely to corrode than metal materials, the beverage container 1 can hold beverages that contain salt.

[0073] The lower container 10 has a ring-shaped protrusion 14 that protrudes radially, and the inner container 40 has an engagement portion 42 formed on the outer periphery that engages with the protrusion 14 and is disengaged from the protrusion 14 by elastic deformation of the inner container 40.

[0074] According to this configuration, the inner container 40 disengages from the protrusion 14 due to elastic deformation, so the user can apply force to the inner container 40 with their fingertips to disengage it from the protrusion 14, making it easy to attach and detach the inner container 40 from the lower container 10.

[0075] An air-insulated space 18 is provided between the lower container 10 and the inner container 40 .

[0076] 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, which provides a high level of heat and cold insulation for beverages in the inner container 40.

[0077] The axial force connecting the upper container 20 to the lower container 10 presses the upper container 20 against the inner container 40, thereby sealing the gap between the upper container 20 and the inner container 40.

[0078] According to this configuration, there is no need for a separate packing between the upper container 20 and the inner container 40, and the configuration of the beverage container 1 can be simplified.

[0079] The container further includes a cup member 30 connected to the upper end 21 of the upper container 20, and an annular seal portion 38 that abuts against the drinking spout member 50 is provided on the inner periphery of the cup member 30.

[0080] According to this configuration, the cup member 30 and the drinking spout member 50 are sealed by the seal portion 38 provided on the inner periphery of the cup member 30, so there is no need for a separate packing on the cup member 30. This allows the configuration of the beverage container 1 to be simplified.

[0081] A straw member 70 or a nipple member 60 for placing in the mouth of an infant can be attached to the drinking spout member 50.

[0082] According to this configuration, when the subject to drink the beverage is an infant, the nipple member 60 can be attached to the spout member 50, and when the subject to drink the beverage is a child, the straw member 70 can be attached to the spout member 50. As a result, the beverage container 1 can be used even when the subject to drink the beverage grows from an infant to a child, and the beverage container 1 can be used for a long period of time from the birth of the child.

[0083] Instead of the upper container 20, a lid member 80 that closes the opening of the lower container 10 can be connected to the top 11 of the lower container 10.

[0084] 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 reduced. Also, since the proportion of non-insulated space is smaller than when the upper container 20 is used, the insulation of the beverage is improved.

[0085] Although the embodiments of the present invention have been described above, the above embodiments merely illustrate some of the application examples of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configurations of the above embodiments.

[0086] For example, each container or member other than the lower container 10 may also have a double wall for heat insulation, and the cup member 30 or the top plate 81 of the lid member 80 may also have a double wall. [Explanation of symbols]
