The upper container 20 has an annular exposed portion 23 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 polymeric material such as transparent or translucent plastic or glass, the beverage in the beverage container 1 can be visually recognized through the exposed portion 23 . Note that the polymer material includes elastomer including rubber such as silicone rubber, plastic, and other materials containing polymer as a main component.

As shown in FIG. 1, the exposed portion 23 is provided with a scale 24 consisting of a plurality of scale lines 24a to 24g for checking the amount of beverage in the beverage container 1. As shown in FIG. Each of the scale lines 24a to 24g consists of a pair of opposing lines drawn obliquely with respect to the vertical direction. Between the scale lines 24b, a numerical value "100" indicating 100 cc is marked. Similarly, between the scale lines 24d and between the scale lines 24f, numerical values for confirming the respective amounts are marked. 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 orientation (see FIG. 7).

As shown in FIG. 2, the upper container 20 includes 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 to which the drinking spout member 50 is attached. , have 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 . A male screw 27 connected to the lower container 10 is provided on the outer circumference of the lower connecting portion 25 .

The upper connecting portion 26 has a large diameter portion 26a having substantially the same outer diameter as that of the lower connecting portion 25, and a small diameter portion 26b having an outer diameter smaller than that of the large diameter portion 26a. A male screw 28 to which the cup member 30 is connected is provided on the outer circumference of the large diameter portion 26a. An attachment portion 29 to which the spout member 50 is attached is provided on the outer periphery of the small diameter portion 26b. The mounting portion 29 is, for example, an annular protrusion for locking the mouthpiece member 50 by contact friction with the inner periphery of the mouthpiece member 50 .

Next, the cup member 30 will be explained. As shown in FIGS. 1, 2 and 6, the cup member 30 is formed with a cup portion 31 covering one end of the upper container 20 and a hole 34 through which a finger or a carabiner is passed. and a handle 32 for holding. The cup portion 31 is provided with unevenness 33 for improving the grip of 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). can improve the texture of

The cup member 30 is a member that serves as a cup for pouring and drinking a beverage, and can stand on its own with a planar top portion 35 as the bottom. A female thread 37 (see FIG. 6) is provided inside the open end 36 of the cup member 30 and is screwed with the male thread 28 of the upper container 20 .

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 an elastically deformable polymeric material. In this embodiment, the inner container 40 is made of silicone rubber or thermoplastic elastomer. The inner container 40 has a top portion 41 that abuts on the lower end 22 of the upper container 20, an engaging portion 42 that engages with the projecting portion 14 of the lower container 10, and an inner container body 43 that accommodates the beverage.

As shown in FIG. 4 , the engaging portion 42 is provided on the outer circumference of the inner container 40 so as to engage with the projecting 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 portion of the inner container main body 43 . That is, the engaging portion 42 is recessed from the outer peripheral surfaces of both the top portion 41 and the inner container main body 43 .

The outer diameter of the inner container main body 43 gradually decreases toward the bottom, and the lower outer diameter W4 of the inner container main body 43 is formed smaller than the upper outer diameter W3 of the inner container main body 43. . As a result, when the inner container main body 43 passes through the protruding portion 14, resistance due to contact with the protruding portion 14 is greater when the lower side of the inner container main body 43 passes than when the upper portion of the inner container main body 43 passes. small. Therefore, it is easy to accommodate the inner container 40 in the lower container 10 .

When removing the inner container 40 from the lower container 10, insert 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 to elastically push the inner container 40 inward. Transform and remove. Also, the inner container 40 is elastically deformed by pinching a portion of the top portion 41 with the fingertips and pulling upward, so that the inner container 40 can be removed from the lower container 10 . Furthermore, the inner container 40 can be removed from the lower container 10 while being elastically deformed by placing a fingertip on the inclined portion 44 formed on the back side of the engaging portion 42 and pulling upward. In this manner, the engaging portion 42 is disengaged from the projecting portion 14 due to the elastic deformation of the inner container 40 .

When the engaging portion 42 is engaged with the projecting portion 14 , the inner container 40 is supported by the projecting portion 14 , and air is present between the inner wall 12 a of the lower container 10 and the inner container main body 43 of the inner container 40 . A heat insulating space 18 is formed. Therefore, the beverage inside the inner container 40 is kept warm or cold by the heat insulating space 13 and the heat insulating space 18, and the inner container 40 accommodated in the lower container 10 is more suitable than a beverage container having only a vacuum double structure. High heat and cold insulation effect. In order to prevent the shape of the inner container 40 from being greatly deformed 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 main body 43. good.

Next, the drinking mouth member 50, the teat member 60 and the straw member 70 will be described. As shown in FIGS. 2 and 6, the mouthpiece member 50 is a cylindrical member with an upper end 51 and a lower end 52 that are open. The user can drink the beverage directly by touching the opening of the upper end 51 with his/her lips, and can also pour the beverage into the cup portion 31 through the opening of the upper end 51 .

Also, a nipple member 60 or a straw member 70 can be attached to the spout member 50 . As shown in FIG. 6, when the nipple member 60 is attached to the mouthpiece member 50, the nipple member 60 is inserted through the opening of the lower end 52 of the mouthpiece member 50, protrudes from the opening of the upper end 51, and attached to the mouthpiece member 50. be done. At this time, the nipple member 60 is sandwiched between the mouthpiece member 50 and the upper container 20 with the flange-shaped engagement portion 61 engaged with the engagement portion 54 formed inside the mouthpiece member 50 . be. A nipple member 60 attached to the mouthpiece member 50 is housed inside the cup member 30 .

When the straw member 70 (see FIG. 2) is attached to the mouthpiece member 50 , the straw member 70 is inserted through the opening of the upper end 51 of the mouthpiece member 50 . A straw member 70 attached to the spout member 50 is also housed inside the cup member 30 .

Thus, the beverage container 1 can be used with the nipple member 60 attached to the mouth member 50, used with the straw member 70 attached to the mouth member 50, used with the mouth member 50 alone, and used with the cup member 30. A different mode of use is possible, the use of . Therefore, the beverage container 1 can be used by everyone from infants to adults. Specifically, infants can drink breast milk or prepared milk in the beverage container 1 . In addition, children can drink milk or sports drinks contained in the beverage container 1.例文帳に追加Moreover, various beverages for adults can be put in the beverage container 1. - 特許庁The beverage container 1 can carry various kinds of beverages while keeping them warm or cold without limiting the use to infants or babies past the nursing period in the process of growing up after the birth of the child. Among them, baby bottles are no longer used after a child passes infancy, but the drink container 1 can be used for a long time (that is, for a long life) because it can be used regardless of the season from infants to adults.

Next, the lid member 80 will be explained. 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 that is connected to the lower container 10 . A male thread 83 to be 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. The lower end of the connecting portion 82 is in close contact with the upper end surface 41a (see FIG. 4) of the top portion 41 of the inner container 40, thereby sealing the gap between the lid member 80 and the inner container 40. As shown in FIG.

When the lid member 80 is used, the height of the beverage container 1 can be reduced compared to the case where the upper container 20 and the cup member 30 are used with respect to the lower container 10, and the surface area of the non-insulated structure of the beverage container 1 as a whole can be reduced. The heat insulating property of the beverage is enhanced due to the smaller .

Next, the sealing structure by each member is demonstrated with reference to FIG.5 and FIG.6.

First, 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 male screw 27 of the upper container 20 and the female screw 16 of the lower container 10 together. 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 of screwing the upper container 20 into the lower container 10 causes the lower end surface 22a and the upper end surface to contact each other. 41a are tightly sealed.

That is, when the upper container 20 is attached to the lower container 10, the inner space of the upper container 20 and the inner container 40 accommodated in the lower container 10 are 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 are brought into contact with each other and sealed. Thus, the inner container 40 (upper end surface 41a) made of polymeric material also serves as a packing.

Next, 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 force of the upper container 20 pressing the inner container 40 downward causes the upper horizontal surface 45 formed at the engaging portion 42 of the inner container 40 to move downward. It is pressed against the protrusion 14 of the container 10 . As a result, the upper horizontal surface 45 and the projecting portion 14 are brought into close contact and sealed.

Next, sealing by the mouthpiece member 50 will be described. As shown in FIG. 6, the inner periphery of the connecting portion 53 of the spout member 50 abuts against the mounting portion 29 of the upper container 20, thereby sealing the gap between the spout member 50 and the upper container 20. As shown in FIG.

Further, when the nipple member 60 is held between the mouthpiece member 50 and the upper container 20, the flange-like engaging portion 61 of the nipple member 60 and the upper end 21 of the upper container 20 are in contact with each other and sealed. As a result, the internal spaces of the upper container 20 and the nipple member 60 are integrated.

In addition, as shown in FIG. 6, on the inner periphery of the cup member 30, a seal portion 38 is formed in an annular shape so as to correspond to the outer peripheral portion 51a of the upper end 51 of the drinking spout member 50. be done. When the cup member 30 is screwed into the upper container 20 to the lower limit position, the outer peripheral portion 51a and the seal portion 38 are brought into close contact with each other and sealed to prevent the beverage from leaking to the outside.

The mouthpiece member 50 is made of an elastically deformable material such as rubber, and when the outer peripheral portion 51a and the seal portion 38 come into contact with each other, the outer peripheral portion 51a deforms so as to widely conform to the shape of the seal portion 38. Get closer. On the other hand, the engaging portion 54 formed inside the mouthpiece member 50 is made of a non-deformable material such as plastic, reliably compresses the engaging portion 61 of the nipple member 60, and maintains close contact with the nipple member 60. Increased. In this way, the mouthpiece member 50 may be configured by combining elastically deformable parts (not shown) and non-deformable parts (not shown), or may be configured by a single member.

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

Further, when the cup member 30 is screwed into the upper container 20 to the lower limit position, the tip portion 63 of the nipple member 60 comes into contact with the center portion 39 of the inner bottom of the cup portion 31 and is sealed. Therefore, the beverage is prevented from leaking from the nipple member 60 .

In addition, the drinking spout member 50 may be integrated with the upper container 20 instead of being separate. In this case, the upper end 21 of the upper container 20 is extended so as to contact the seal portion 38 of the cup member 30 , and the seal portion 38 is sealed by the upper container 20 .

By the way, 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.

Therefore, even if a salt-containing beverage such as artificial milk, milk drink, sports drink, soup, or rice porridge is put in the beverage container 1, the lower container 10 does not come into contact with the beverage. not corroded by 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 polymeric materials that are not corroded by the salt contained in the beverage, so that various beverages can be accommodated.

Also, if the container is made of metal, sterilization by boiling may damage the double wall of the vacuum structure, and sterilization by chemical liquid may corrode the metal. Furthermore, metal containers cannot be sterilized in a microwave oven because metal materials can cause sparks and fires when exposed to microwaves in a microwave oven.

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

In other words, the beverage container 1 has a heat insulating structure with a double wall 12 under the usefulness of a metal material that is excellent in workability and durability, and has a "possibility of corrosion" and "cannot be easily disinfected." The difficulty of metal materials such as "" is solved by adopting a structure in which the lower container 10 does not come into contact with the beverage. As a result, the beverage container 1 can contain a beverage containing salt or a beverage that may spoil, and the beverage can be carried with a high heat/cold insulation effect. Furthermore, the beverage container 1 can be used for a long life because it can be used in a plurality of ways through the mouthpiece member 50 .

In addition, when the beverage spoils, gas is generated and the expansion pressure is applied from the inside, leading to breakage of the container and accidents. disappears. As a result, in the beverage container 1, the risk of spoilage of the next-filled beverage is reduced, thereby reducing the risk of breakage of the container and accidents.

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

As shown in FIG. 7, the beverage container 1 can be placed in a stable stationary state by placing the lower container 10 and the handle 32 thereon. The resting state is a posture for checking the amount of beverage in the beverage container 1, and is called a horizontal posture because the beverage container 1 is left standing obliquely sideways. The horizontal placement posture includes a posture in which the beverage container 1 is placed at an angle and a posture in which the beverage container 1 is placed horizontally, but does not include a posture in which the beverage container 1 is placed upright.

When the beverage container 1 is placed horizontally, the grounding portion 10a of the lower container 10 and the grounding portion 32a of the handle 32 are in contact with the installation surface 100. - 特許庁Since the grounding portion 32a has a predetermined width with respect to the installation surface 100, the horizontal position of the beverage container 1 is stabilized. In this way, the handle 32 is also used as a part for the beverage container 1 to take the horizontal posture. Instead of using the handle 32, a portion may be provided on the outer periphery of the lower container 10 or the cup member 30 so that the beverage container 1 can take the horizontal position. Also, a member different from the handle 32 may be provided on the beverage container 1 to allow the beverage container 1 to take the horizontal posture.

FIG. 7 also shows liquid levels S1 to S7 of beverages when different volumes of beverages are placed in the beverage container 1 to which the nipple member 60 is attached. Below, the liquid levels S1 to S7 will be described in correspondence with the scale lines 24a to 24g shown in FIG.

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

In this manner, the scale lines 24a to 24g are provided corresponding to the liquid level of the beverage when the beverage container 1 is placed horizontally. The reason why the scale 24 is provided on the exposed portion 23 will be described below.

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, it will be exposed. The liquid surface of the beverage cannot be viewed from the side through the portion 23. Further, even when the liquid level of the beverage is at the height of the cup member 30, the liquid level of the beverage cannot be visually recognized from the side through the exposed portion 23 if the cup member 30 is an opaque member.

On the other hand, as shown in FIG. 7, when the beverage container 1 is placed horizontally, the liquid surface of the beverage can be visually recognized through the exposed portion 23 regardless of the amount of the beverage. Therefore, a scale 24 is provided on the exposed portion 23 so that the user can check the amount of the beverage by using the scale 24 while placing the beverage container 1 horizontally.

As described above, the beverage container 1 has a high heat insulating property due to the lower container 10 made of metal with excellent workability and durability, and a structure for checking the amount of beverage due to the upper container 20 made of a transparent or translucent polymer material. have both.

When the user visually recognizes the beverage through the exposed portion 23, the scale lines 24a to 24g are drawn on the inner periphery of the exposed portion 23, considering that the height of the liquid surface is refracted by the exposed portion 23. provided in

Moreover, when the nipple member 60 is not attached, the beverage can be moved from the opening of the mouthpiece member 50 to the inside of the cup member 30 . Therefore, even if the same volume of beverage is put in, the liquid level of the beverage without the nipple member 60 is higher than the liquid levels S3 to S7 with the nipple member 60 attached. Each of them is lower than the liquid surfaces S3 to S7. Therefore, one side of the exposed portion 23 may be provided with scale lines when the nipple member 60 is attached, and the other side of the exposed portion 23 may be provided with scale lines when the nipple member 60 is not attached. At this time, an icon representing the nipple member 60 may be displayed with scale lines on one side of the exposed portion 23 , and an icon representing the spout member 50 may be displayed with scale lines on the other side of the exposed portion 23 .

Further, the scale lines 24a to 24g are not limited to linear scale lines, and may be dashed lines or wavy lines. Also, the graduation lines may be transparent or translucent so that the graduation lines can be visually recognized depending on the color of the beverage when a non-transparent beverage is added. Further, instead of the scale lines, for example, a scale of points (dots) or a scale of only numerical values may be used.
