If the infant accidentally falls down as in the case of above, the contents may leak out from the insertion opening of the straw or the like with the passage of time, and the surroundings may be stained. Moreover, the straw fell on the floor when the container fell, and it was unsanitary to leave it as it was. Further, even when the straw is capped and carried around in a sealed state, the contents may be pushed up from the straw due to the influence of the air pressure inside the container, and the contents may leak to the outside from the cap portion.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to improve the disadvantages of the prior art and, in particular, to provide a beverage container in which the contents are hard to leak.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a beverage container comprising a container, an upper lid, and a straw for sucking out the contents of the container to the outside. Is formed in a spherical shape, and an inner lid is provided between the container and the upper lid to prevent the contents of the container from flowing toward the upper lid. In the present invention, when the container is collapsed, the contents tend to flow toward the upper lid, but are blocked by the inner lid and do not flow toward the upper lid. For this reason, leakage from the upper lid can be prevented. Furthermore, the contents are always stored in the container side by being blocked by the inner lid, and the container side becomes heavy in the folded state. At this time, since the vicinity of the bottom of the container is formed in a spherical shape,
The container rises like a darling, depending on the weight of the contents. For this reason, the inconvenience that the contents do not leak out as a result of leaving the container lying down as in the related art can be prevented. Here, the upper lid and the inner lid do not necessarily have to be formed of independent members, and the upper lid and the inner lid may be formed integrally.

Further, the invention according to claim 2 adopts a configuration in which the thickness of the bottom of the container is formed to be thicker than the thickness of the periphery. In this case, since the bottom is heavier than the surroundings, even when the content of the container is small, the container can be raised like a darling.

Furthermore, the invention according to claim 3 adopts a configuration in which the bottom of the container is recessed toward the inside of the container. By doing so, the bottom of the container fits on the floor, so that the instability when the container is standing can be eliminated. On the other hand, the recessed portion appears as a convex portion inside the container, and for example, a circumferential depression is formed at the foot of the convex portion. Then, when the content is reduced, the content accumulates in this depression, so that it becomes easier to suck with a straw.

The invention according to claim 4 employs a configuration in which a claw for fixing the inner lid is protruded from the upper lid, and a knob for removing the inner lid from the upper lid is formed on the inner lid. I have. By doing so, the inner lid can be fixed inside the upper lid, and the inner lid can be easily removed from the upper lid by holding the knob formed on the inner lid, so that the lid can be easily cleaned.

Further, according to the invention of claim 5, according to claim 1,
In the beverage container described above, a configuration is adopted in which a cup opening is attached instead of the upper lid and the inner lid, and a support for suppressing the container from tipping over is provided. In the present invention, the vicinity of the bottom of the container is formed on a spherical surface, and it is easy to roll as it is. Therefore, when the opened cup is attached, the contents are easily spilled. Therefore, a support for suppressing the container from overturning is provided.

[0010] In the invention according to claim 6, in the beverage container for sucking the contents of the beverage container with a straw from the beverage container in which the container is closed with a lid, an inner cap is provided inside the container to close a mouth of the straw inside the container. The straw is made detachable from the inner cap. In the present invention, since the end of the straw is closed inside the container using the internal cap, it is possible to prevent the inconvenience that the contents are pushed up to the straw and spilled due to the increase in the pressure inside the container.

[0011] In the invention according to claim 7, in the beverage container in which the contents are sucked with a straw from the beverage container whose container is closed with a lid, the straw is extracted from the beverage container at a portion of the straw located inside the beverage container.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG.
A description will be given based on FIGS.

The beverage container shown in FIG. 1 includes a container 1 and an upper lid 2. A handle member 3 is inserted between the container 1 and the upper lid 2. Reference numeral 3a denotes a handle formed as a part of the handle member 3. The container 1 is a transparent plastic container and is formed in a hemispherical shape except for the bottom 4.
The bottom 4 is recessed toward the inside of the container 1. The container 1 is provided with a scale capable of measuring the contents. On the other hand, the upper lid 2 is formed in a hemispherical shape with an opaque plastic material,
An insertion hole 6 for the straw 5 is provided. This insertion hole 6
Has the same diameter as the straw 5 and the surface of the upper lid 2 other than the insertion hole 6 is closed. The outer shape combining the container 1 and the upper lid 2 is substantially spherical.

FIG. 2 is a longitudinal sectional view taken along the plane of FIG. Inside the upper lid 2, a middle lid 7 is detachably attached. The inner lid 7 is formed in a disk shape with a diameter substantially equal to or slightly larger than the diameter of the opening (hemispherical opening) of the upper lid 2. A plurality of claws 2a protrude from the inner wall of the upper lid 2 along the circumference of the opening of the upper lid 2. When the inner lid 7 is pushed into the inside of the claw 2a inside the upper lid 2, the inner lid 7 is pushed. Is locked by a plurality of claws 2 a and fixed inside the upper lid 2. A knob 7a is provided at the center of the surface of the inner lid 7 on the container 1 side. The knob 7a is pinched with a finger to push the inner lid 7 into the upper lid 2, or conversely, the inner lid 7 is closed. 2 can be removed. A straw 5 is provided near the center of the inner lid 7.
Is provided with a through hole 8. This through hole 8 is formed to have a diameter substantially equal to the diameter of the straw 5. The insertion hole 6 of the straw 5 provided in the upper lid 2 is arranged at a position rising from the hemispherical opening surface of the upper lid 2 by about 60 degrees. Also, the bottom 4 of the container 1 is spherically concave toward the inside of the container when viewed from the outside, and conversely rises on the spherical surface when viewed from the inside of the container 1. For this reason,
An annular depression 4a is formed at the foot of the swell. Further, the bottom 4 of the container 1 is formed thicker than the surroundings, and is heavier than the surroundings. The straw 5 is shaped or deformed into the shape of a "ku", and
Through the insertion hole 6 of the inner lid 7 and the insertion hole 8 of the inner lid 7, the end in the container 1 is disposed in the depression 4 a of the bottom 4.

Here, FIG. 3 is an enlarged view of the connecting portion A between the container 1 and the upper lid 2. The cross section of the end of the container 1 connected to the upper lid 2 is bent inward in a crank shape,
The end of the upper lid 2 covers the end of the container 1. A screwing portion 9 composed of a screw thread and a screw groove is formed on the outer surface of the end of the container 1 and the inner surface of the end of the upper lid 2. Connected as possible. In this state, the container 1 and the upper lid 2
, The handle member 3 is sandwiched.

FIG. 4 is a configuration diagram of the handle member 3. The lower figure is a front view, and the upper figure is a plan view. Handle member 3
Has a main body formed in an annular shape, and a pair of handles 3a pulled out from a position on the diameter of the main body. The pair of handles 3a extend in a direction normal to the surface including the annular main body (the back side of the paper). The inner diameter of the annular main body is set to be slightly larger than the diameter of the end of the container 1. Therefore, when the handle member 3 is put on the container 1 before the upper lid 2 is attached, the annular main body just surrounds the periphery of the end of the container 1, and the upper lid 2 is screwed into the container 1 from above. As a result, the cross section of the connection portion appears as shown in FIG. At this time, the handle 3a pulled out from the annular main body is turned to the container side, so that the arrangement of the handle 3a is as shown in FIG. Each component of the beverage container described above is desirably formed of heat-resistant plastic.

Next, the behavior of the beverage container according to the present embodiment will be described with reference to FIG. FIG. 5 shows the same cross section as FIG. When the beverage 11 is placed in the container 1, it is usually stable with the bottom of the container 1 on the floor (FIG. 5).
(A)). Next, for example, when the infant plays with the container and falls down as shown in FIG. 5B, the beverage 11 in the container 1 tends to flow toward the upper lid 2. However, top lid 2
Is closed by the inner lid 7, so that even if the entire container is inclined, the beverage 11 inside is stored in the container 1 side. For this reason, in the state of FIG. 5B, the left side of the figure, which is the container side, is heavier than the right side. For this reason, the whole container cannot maintain the inclined state when the external force is removed, and naturally returns to the normal state as shown in FIG.

According to this embodiment, since the bottom surface 4 of the container 1 is formed in a spherical shape near the bottom and the inner lid 7 is provided so that the beverage in the container 1 does not flow toward the upper lid 2, When the beverage 1 is turned over and the beverage tries to flow toward the upper lid 2, the beverage is blocked by the inner lid 7 and does not flow toward the upper lid 2. Therefore, leakage from the upper lid 2 can be prevented. Further, the beverage 11 is always stored in the container 1 side by being blocked by the inner lid 7, and the container 1 side becomes heavy in a folded state. At this time, since the vicinity of the bottom 4 of the container 1 is formed in a spherical shape, the container 1 stands up like a darling due to the weight of the beverage 11. For this reason, the inconvenience that the contents leak out as a result of leaving the container 1 lying down as in the related art can be prevented without the container 1 falling down.

Further, since the bottom 4 of the container 1 is formed thicker than its surroundings, the bottom 4 becomes heavier than its surroundings, so that even when the amount of the beverage 11 in the container 1 is small, it can be raised like a darling. Can be.

Furthermore, since the bottom 4 of the container 1 is recessed toward the inside of the container 1, the bottom 4 of the container 1 fits on the floor, and the instability when the container 1 stands can be eliminated. Also,
The recessed portion appears as a convex portion inside the container 1, and a circumferential depression 4 a is formed at the foot of the convex portion. Then, when the amount of beverage is reduced, the depression 4a
The contents accumulate in the straw, making it easier to suck with a straw.

Further, a claw 2a for fixing the inner cover 7 is projected from the upper cover 2 and a knob 7a for removing the inner cover 7 from the upper cover 2 is formed on the inner cover 7, so that the inner cover 7 is 2
And a knob 7 formed on the inner lid 7.
It is also easy to remove the inner lid 7 from the upper lid 2 while holding a. Therefore, the lids 2 and 7 can be easily cleaned.

In addition, by forming the inner lid 7 from an elastic body, the degree of sealing of the upper lid 2 by the inner lid 7 can be increased, and the degree of sealing of the through hole of the straw 5 provided in the inner lid 7 can also be improved. Can be enhanced. In addition, a situation in which the beverage leaks from the joint between the container 1 and the upper lid 2 by inserting an elastic material into the contact surface between the handle member 3 and the container 1 or the contact surface between the handle member 3 and the upper lid 2 is also effective. Can be prevented.

Next, another embodiment of the present invention will be described with reference to FIGS. Here, the same portions as those of the above-described embodiment are denoted by the same reference numerals, and the description thereof will not be repeated.

FIG. 6 is a longitudinal sectional view of the beverage container according to the present embodiment. In the present embodiment, a mounting portion 21 is protruded below the inner lid 7, that is, on the container 1 side, and an arm 22 is mounted on the mounting portion 21. The arm 22 is formed of, for example, heat-resistant plastic and has a hardness that does not easily deform. This arm 2
2 is detachable from the mounting part 21. The arm 22 extends from the mounting portion 21 toward the center of the bottom 4 of the container.
An inner cap 23 capable of closing the inner end of the container is formed. The straw through-hole portion 24 of the inner lid 7 is formed to be thicker than its surroundings, so that the contents are less likely to leak from the contact surface with the straw 5 to the upper lid 2 side. Also, the straw through-hole portion 25 of the upper lid 2 is
Is formed in a convex shape with a predetermined thickness toward the outside of the
Thus, care is taken to prevent the contents from leaking from the contact surface with the straw 5. Here, reference numeral 26 denotes a cap that seals the space around the straw opening. The cap 26 detachably fits with the convex shape of the straw through-hole portion 25 to form a closed space around the straw opening. Reference numeral 27 denotes a stopper protruding from the outer surface of the straw, and when the straw 5 is pulled,
This is to prevent the straw from being pulled out from the inner lid 7 and the upper lid 2. The reason is that if a toddler or the like accidentally pulls out the straw, the straw through-holes in the upper lid 2 and the inner lid 7 are opened, and the contents are liable to leak. Other parts are formed the same as the beverage container of the embodiment described above.

The beverage container of the present embodiment is used as follows. When putting the contents in the container 1, the contents are poured into the container 1 with the upper lid 2 and the inner lid 7 removed. On the other hand, the inner lid 7 is attached to the upper lid 2, and the straw 5 is inserted into both of them in advance. Further, the arm 22 is attached to the inner lid 7 in advance, and the tip of the straw 5 on the inner side of the container is inserted into the inner cap 23 in advance. At the stage where the preparation so far is completed, the upper lid 2 and the inner lid 7 are attached to the container 1. Also, the cap 26 is attached.

According to this, since the end of the straw 5 inside the container is closed by the internal cap 23, even if the pressure inside the container 1 rises, the contents are pushed up to the straw 5 and leak out to the outside. Can be prevented. For this reason, even if it is put in a bag when going out, it is not necessary to stain the inside of the bag.

On the other hand, when drinking the contents, the cap 26
And pull the straw 5 a little. Then, inside the container, the tip of the straw 5 is
, For example, the straw 5 moves to the position shown by the dotted line, and becomes ready to suck the contents. At this time, if the pressure inside the container is increased, the contents may protrude from the straw. Therefore, before removing the straw 5 from the inner cap 23, the upper lid 2 and the inner lid 7 are temporarily removed from the container 1, It is desirable that the pressure inside the container is balanced with the outside.
After use, the container and the like are washed, but the arm 22 can be removed from the inner lid 7 so that it is easy to wash. The means for preventing the straw from leaking by the inner cap as in the present embodiment can be widely used for a beverage container in which the contents are sucked out of a closed container with a straw, and the shape of the container is not limited.

Next, still another embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a configuration diagram in which an annular cup opening 30 is attached instead of the upper lid 2 and the inner lid 7 used in the embodiment described above. The attachment of the cup opening 30 to the container 1 is performed by screwing in the same manner as the above-described upper lid 2. When such a cup opening 30 is attached, since the bottom of the container 1 is spherical, the container 1 easily falls down as it is, and the contents easily spill out from the cup opening 30. In this embodiment, the handle member 3 is deformed so that the container 1 does not fall.

In this embodiment, the handle member 31 is formed as shown in FIG. The lower figure is a front view, and the upper figure is a plan view. The shape is such that the handle 3a of the handle member 3 appearing in the previous embodiment is extended to a position that is substantially flush with the bottom surface of the container 1, and its distal end has an annular shape in a plane parallel to the bottom surface of the container 1. The support 31b is formed. It is desirable that the vertical length of the handle 3a be substantially the same as or longer than the height of the container 1, but it is also possible to make it slightly shorter than the height of the container 1. As shown in FIG. 7, in this embodiment, the opening surface of the cup opening 30 and the surface including the annular support 31b are parallel to each other, and the contents are hardly spilled. As described above, since the shape of the handle member is deformed to provide the support for the container 1, the contents can be prevented from being spilled even when the cup opening is attached.

Here, the present invention is not limited to the above embodiments. The range in which the container is formed into a spherical shape is not limited as long as it is made for the purpose of raising the container. The mounting position of the inner lid is not limited to the inside of the upper lid, it may be attached to the container side,
It may be attached by sandwiching between the upper lid and the container. It is not necessary to make the bottom of the container concave in a spherical shape, and for example, it may be a rectangular concave. Further, the method of making the bottom heavier than the surroundings may be a method of attaching a weight to the bottom in addition to forming the bottom member thicker. The method of locking the inner lid is not limited to the claw-shaped projection, but may be, for example, a method in which a key-shaped engaging portion is provided which meshes with the upper lid or the container by rotating the inner lid relative to the container. In addition to the above-mentioned upper lid and cup opening, a lid provided with a suction opening, a lid provided with a nipple-shaped suction opening like a baby bottle, and the like can be attached to the container. In the case of a lid provided with a mouthpiece, if the mouthpiece is formed in a horizontally long or elliptical shape, it is easy to suck in conformity with the opening shape of a human mouth. The support of the container is not limited to an annular shape, and any shape may be used as long as the container can be prevented from tipping over. The inner cap may not be attached via the arm, and may be formed integrally with the inner wall of the container, for example. The mounting portion of the arm of the inner cap may be provided other than the inner lid. The arm of the inner cap does not necessarily have to be detachable from the mounting part.

[0031]

Since the present invention is constructed and functions as described above, according to the present invention, the vicinity of the bottom surface of the container is formed into a spherical shape, and the inner lid is prevented from flowing the contents of the container to the side of the upper lid. Is provided, even if the container is collapsed and the contents try to flow toward the upper lid, the contents are blocked by the inner lid and do not flow toward the upper lid. For this reason, leakage from the upper lid can be prevented. Furthermore, the contents are always stored in the container side by being blocked by the inner lid, and the container side becomes heavy in the folded state. At this time, since the vicinity of the bottom of the container is formed in a spherical shape, the container rises like a darling due to the weight of the contents. For this reason, the inconvenience that the contents do not leak out as a result of leaving the container lying down as in the related art can be prevented.

According to the second aspect of the present invention, the bottom of the container is formed to be thicker than the surroundings, so that the bottom is heavier than the surroundings, so that even when the container has a small amount of beverage, it can be shaped like a doll. You can get up.

Furthermore, in the third aspect of the present invention, since the bottom of the container is recessed toward the inside of the container, the bottom of the container fits on the floor, and the instability when the container stands can be eliminated. In addition, the recessed portion appears as a convex portion inside the container, and a circumferential depression is formed at the foot of the convex portion. Then, when the content is reduced, the content accumulates in this depression, so that it becomes easier to suck with a straw.

According to the fourth aspect of the present invention, a claw for fixing the inner lid is protruded from the upper lid, and a knob for removing the inner lid from the upper lid is formed on the inner lid. And the inner lid can be easily removed from the upper lid with the knob formed on the inner lid. For this reason, the lid can be easily cleaned.
