However, in such a beverage container 1, when a relatively high-temperature liquid is stored in the container body 2, the internal space S1 of the container is reduced.
There is a problem that the volume of air existing in the container expands due to the heat of the high-temperature liquid, so that the high-temperature beverage blows out through the straw 4 and is dangerous. In particular, when an infant drinks milk after preparing the milk, the above-mentioned adverse effects can be easily expected after the milk powder is put in the container body and stirred with high-temperature hot water.
Further, even when a cold beverage is stored in a container, if the beverage is placed in a warm room, the same phenomenon may occur because the air in the container is heated by the room temperature.

Therefore, an improvement as shown in FIG. 31 has been made. In the figure, the beverage container 5 includes a cap portion 6 for closing an upper opening of the lid member 3, and a base member 7 of the cap portion 6 is mounted. This base member 7
Has a through-hole through which the straw 4 passes, and a slit-like through-groove 8 extending laterally from the through-hole.

As described above with reference to FIG. 16, when the internal pressure is increased in the container body 2, the pressure can be released to the outside through the through groove 8, thereby preventing the beverage from being blown out from the straw. it can.

However, in such a beverage container 5, when the container main body 2 is tilted, the liquid beverage leaks from the through-groove 8, and especially when used by infants,
There is a disadvantage that the liquid beverage is easily spilled.

The present invention has been made in order to solve such a problem. In a beverage container using a straw, it is possible to prevent the liquid beverage from blowing out from the straw and to prevent the liquid beverage from leaking to the outside. It is an object to provide a beverage container that can be prevented.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are added. However, the scope of the present invention particularly limits the present invention in the following description. The embodiment is not limited to these embodiments unless otherwise stated.

FIG. 1 is a schematic perspective view showing the whole of a first embodiment of the beverage container of the present invention. In the figure, a beverage container 10 includes a container body 12 formed in a cup shape from, for example, transparent glass or plastic. The upper end of the container body 12 has an open opening, and a lid member 13 is attached so as to close the opening. That is, for example, the lid member 13 can be attached and detached by being screwed into a screw portion (not shown) formed around the upper end opening of the container body 12. Thereby, when the lid member 13 is removed, the upper end of the container main body 12 is widely opened, so that it is easy to add a liquid beverage or mix powdered milk with hot water to prepare the milk. . Further, for example, a pair of handles 11 are integrally formed on a side surface of the container body 12. The handle 11 may be configured to be detachable.

The lid member 13 is connected to the container body 12 as described above.
Is closed so that the stored beverage does not spill even if the container body 12 is tilted. Further, the lid member 13 supports the straw 14 in a state where the straw 14 projects from the upper surface thereof. For this purpose, the container body 12 is provided with a lid opening (described later) at the upper end, and the base member 17 of the cap portion 16 is attached to this opening. That is, the cap portion 16 is provided with the dome-shaped cap body 15.
And the base member 17, and the cap body 15 and the base member 17 are connected by a connecting member 18 made of a relatively flexible material like a belt.

The base member 17 is a cover-like member that covers the opening, and as shown in FIG.
First through-hole 2 as first communication means into which the first through hole 4 is inserted
1 and second through holes 22 as second communication means. This first through-hole 21 is
Is formed slightly larger than the diameter of. The second through hole 22 is formed in a region around the first through hole 21, and in this case, is formed as two arc-shaped through holes 22. The through holes 22 constitute a part of an internal pressure adjusting unit 24 described later. The opening area of the first through hole 21 and the opening area of the second through holes 22 are determined as described later.

FIGS. 2 to 4 are partially enlarged views showing the vicinity of the lid opening 23 of the lid member 13 on which the base member 17 is mounted. FIG. 2 is a partially enlarged plan view of FIG.
2 is a sectional view taken along line AA of FIG. 2, and FIG. 4 is a sectional view taken along line BB of FIG. In these figures, a lid opening 23 is formed at the center near the upper end of the upper surface of the lid member 13. The diameter of the lid opening 23 is set larger than the first through hole 21 of the base member 17 described above.

As shown in FIG. 2, around the lid opening 23, two communication holes and two closing portions are formed in each of the four divided areas. That is, with respect to the center of the lid opening 23, the closing portion 2 having the same height as the outer peripheral edge 27 of the lid opening so as to be at a position of 180 degrees from each other.
6, 26 (see FIG. 3) are provided. In addition, communication holes 25, 25 are formed between the closing portions 26, 26 so as to be at 180 degrees from each other. The communication hole 2
As shown in FIG. 4, the outer peripheral portions 5 and 25 have the same height as the outer peripheral edge 27 of the lid opening 23, respectively, and
3 is formed by an inclined hole gradually descending inward toward the lower end. The lid opening 23 and the communication holes 25 and 2
5 and the through holes 22 formed in the base member 17 of the cap portion 15 constitute the internal pressure adjusting means 24.

As shown in FIGS. 5 and 6, a cap portion 16 is attached to the lid member 13. That is, as described above, the cap portion 16 includes the dome-shaped cap body 15 and the base member 17. The cap body 15 and the base member 17 are connected by the belt-shaped connection member 18. I have. The base member 17 is a cover-shaped member having a substantially flat upper surface, and is mounted via a ring-shaped member 28 so as to cover the lid opening 23 of the lid member 13. As shown in FIG.
As described in the above, the first through hole 21 as the first communicating means into which the straw 14 is inserted, and the second through holes 22 as the second communicating means.

The cap body 15 of the cap portion 16 is formed in a transparent dome shape using, for example, a synthetic resin having a certain degree of elasticity, and the connecting member 18 is bent or extended, so that the structure shown in FIG. Open and close in the direction of the arrow. When the cap main body 15 is closed as shown in the figure, the peripheral edge (near the lower end) of the cap main body 15 is deformed, so that the lower peripheral edge 29 of the lower end of the base member 17 is forced into the inside of the cap main body 16. It is adapted to be fitted. The cap body 1 of the cap section 16
The connecting member 18 for connecting the base 6 to the base member 17 may be omitted. Further, in this case, if a knob piece or the like is provided around the base member 17, the rotation becomes easy.

The cap body 15 is connected to the base member 17.
The cap body 15 may be formed small and attached to the tip of the straw 14 without being connected to the straw. Still further, the cap body may be formed in a large size without connecting the cap body 15 to the base member, and may be constituted by a hood-shaped member capable of covering the entire upper portion of the lid member 13. Further, the cap body 15 may be omitted. In this case, preferably, the straw 14 is formed of a flexible material so as to protrude outside long, and is folded back in the middle, and the tip of the straw is fitted into a recess or opening formed on the upper surface of the lid member 13 and fixed. You may make it.

This embodiment is configured as described above, and its operation will be described below. When the cap portion 16 is rotated around the lid opening portion 23, the arc-shaped second through holes 22, 22 shown in FIG. It is turned to the first position by turning in the direction of the arrow shown by. When the second through holes 22, 22 assume the positions shown in FIG. 2 with respect to the lid member 13, as shown in FIG. 6, the second through holes 22, 22, of the base member 17,
The lower part is closed by closing parts 26, 26 of the lid member 13, and these through holes 22, 22 do not communicate with the lid opening part 23.

Therefore, the liquid beverage (not shown) stored in the container body 12 does not leak to the through holes 22 and 22. At this time, if the straw 14 (see FIG. 1) is inserted into the lid opening 23, the only place where the inside of the container body 12 and the outside communicate with each other is the liquid inside the container body 12. The beverage does not spill outside even if the beverage container 10 is tilted.

Further, the cap portion 16 is rotated by 90 degrees from the above-mentioned position around the lid opening portion 23 and moved to the second position. Then, the base member 1 shown in FIG.
The second arc-shaped second through-holes 22 rotate relative to the lid member 90 by 90 degrees in the direction of an arrow indicated by a chain line in FIG. This state is shown in FIG. 5, and in this position, the base member 17 constituting the internal pressure adjusting means 24 of FIG.
The second through holes 22, 22 and the communication holes 25, 25 are communicated with each other.

Thus, as shown by the arrow in FIG.
For example, when a relatively high-temperature liquid is contained in the container main body 12, the air A heated by the liquid A flows through the lid opening 23, the communication holes 25, 25, and the second through holes 22, 2.
2 to the outside. Therefore, if the cap body 15 is opened, the expanded air A is
The beverage is discharged to the outside of the beverage container, and the pressure in the container body 12 decreases. Thereby, the danger that the air confined in the container main body 12 is heated and expanded to push up the liquid beverage through the straw 14 and the hot liquid beverage blows out from the straw 14 is avoided. Moreover, if the cap member 15 is rotated to set the base member 17 at the first position, even if the beverage container 10 is inclined, the liquid beverage in the container body 12 hardly leaks to the outside.

Here, regarding the straw 14 of FIG. 1, in the case of a straw made of polyethylene, which is a relatively hard material,
The outer diameter is 6.2 mm plus or minus 0.1 mm (maximum diameter 6.3 mm), or in the case of a hydrogenated styrene isoprene copolymer resin which is a relatively soft material and a straw made of silicon, the outer diameter is 6. 5 mm plus or minus 0.15 mm (maximum diameter 6.65 mm), the diameter of the first through hole 21 is 8 mm, and approximately 160 until the eighth minute of the container body.
Experiments were performed on blowing, etc., when the area of the second through-holes 22 (sum of the areas of the two through-holes) was changed in a case where milliliters of hot water of 80 degrees Celsius was added. In this case, it is preferable that the area of the second through-hole (the sum of the areas of the two through-holes), which is a main component of the internal pressure adjusting means 24, is 10 square millimeters or more. When the area of the second through hole is smaller than the above lower limit value, blowout in a state where the cap main body 15 is removed is recognized, and it has been confirmed that the second through hole reaches a practically dangerous range. Also, the upper limit of the area of the second through hole is not always provided. Even if this area is large, if the cap body 15 is closed, the liquid does not leak even when the container is tilted. However, in consideration of the convenience in a case where the cap body 15 is opened and a milk preparation operation such as powdered milk is performed and the cap body 15 is used as it is, if the infant uses the cap body 15 without closing the cap body 15 If the area of the through hole 2 is too large, the amount of leakage of the liquid will increase. In this regard, it has been confirmed that if the area of the second through hole is 13 square millimeters or less, the amount of liquid leakage can be kept within a range that does not cause practical inconvenience. In addition, in actual use, the straw 14 is closed when the cap body 15 is completely closed.
When the liquid is sucked through, the pressure inside the container body 12 is reduced,
Since it is difficult to drink, the area of the second through hole of the lid member 13 is convenient when the area of the second through hole is set to 13 mm 2 or less and the cap body 15 is used in an open state.

FIGS. 7 to 9 show a second embodiment of the present invention. In FIG. 7, with respect to the beverage container 30 of the second embodiment, the portions denoted by the same reference numerals as those of the first embodiment have the same configuration.

Thus, even when the beverage container 30 is tilted, the liquid beverage in the container body 12 hardly leaks outside. Next, for example, when a relatively high-temperature liquid is stored in the container body 12,
As a result, the air expanded by heating pushes up the valve element 33 in the valve box 32 as shown in FIG. As a result, the lid opening 35 communicates with the communication ports 34, 34, and this air is discharged to the outside from the communication ports 34, 34, and the pressure in the container body 12 decreases. As a result, the air confined in the container body 12 is heated and expanded, and pushes up the liquid beverage through the straw 14, whereby
The danger of hot liquid beverage blowing out of the straw 14 is avoided.

FIGS. 10 to 12 show a third embodiment of the present invention.

In this case, the rotating body 1
Since the opening area is adjusted by screwing the screws 41, for example, when a scale or the like is formed at a predetermined position of the upper surface of the rotating body 141 and the lid member 13, the scale corresponds to the size of the opening area. A guide can be provided, and the user can easily adjust the opening area. Also, the lid member 1
Instead of directly forming a female screw in the third second opening 13a, a separate female screw member 142 is fitted. Here, since the lid member 13 has a screw engaging portion between the lid member 13 and the container body (see FIG. 24), the lid member 13 is engaged with the container body 12 when a mold for molding the lid member 13 is created. There is no need to provide a screw part separately from the joint part, and the mold can be easily made. Further, the rotating body 141 is provided with a packing 145.
, So that when it is fully tightened, the sealed state is completed. In this modification, the opening area of the through hole 147 of the female screw member 142 is set to be equal to or greater than 10 square millimeters, and preferably equal to or less than 20 square millimeters.

In the third modification shown in FIG.
A core member 155 is formed on the main body 122 of the main body. Core material 15
5 has a locking portion 151 at the lower end.
51 is rotatably fixed by being fitted into a through hole formed in the lid member 13. For this reason, the through-hole 154 that should communicate with the second opening 152 of the lid member 13
Are formed in the main body 122, and a through hole 153 is formed in the core 155 so as to communicate with the main body 122. Therefore, also in this modification, the same operation and effect as in the eleventh embodiment can be exerted by rotating the rotating body 121.

The present invention is not limited to the above embodiment.
In the first embodiment, the through-hole formed in the base member of the cap portion and the communication hole formed in the lid opening may have other shapes and forms.
