In this way, the beverage container equipped with a straw has a structure that makes it easy to drink the content liquid in the container using the straw. However, in a beverage container equipped with such a straw, while having a function of venting air inside the container, the operability of locking and unlocking the operation part for opening the lid is improved, the structure is simplified, and the durability of the straw is durable. Further improvement in sex is desired.

An object of the present invention is to improve operability, simplify the structure, and improve the durability of a straw in a beverage container stopper and a beverage container provided with a straw.

One aspect of the present invention is attached to the opening of the container body having an opening at the top, and is held by the plug body having a vent hole for the inside of the container body and the plug body in a state of penetrating the plug body, and at least from the plug body. A straw that can be elastically deformed at the part protruding upward, a lid that can be opened and closed freely via a hinge on the stopper body, an operation unit that opens the lid, and an operation unit that locks and unlocks the operation unit. It is a stopper for a beverage container provided with a slide portion for the purpose. In this beverage container stopper, the lid is urged to open by the restoring force of the elastically deformed straw by closing the lid, and the slide portion is placed on the outside of the operation portion and along the operation portion. The operation unit is provided so as to be slidable in the vertical direction, and the operation unit is provided so as to be able to move forward and backward in the radial direction of the plug body together with the slide unit. Further, when the lid is closed, the passage of the straw is blocked by the protruding portion of the lid, and the ventilation hole is sealed by the side surface opposite to the protruding portion of the straw.

According to such a configuration, the slide portion is covered on the outside of the operation portion, and these are provided so as to be able to advance and retreat in the radial direction, so that the mechanism in which the operation portion and the slide portion are set is simplified. Further, since the operation portion and the slide portion do not swing and move forward and backward in the radial direction, the protrusion during operation such as swing does not occur. Further, since the ventilation holes are sealed by the side surface of the straw, it is not necessary to provide a special mechanism for sealing the ventilation holes.

In the above-mentioned beverage container stopper, when the lid is closed and the ventilation holes are sealed by the side surface of the straw, the side surface of the straw is preferably bent at an obtuse angle. When the ventilation holes are sealed by bending the straw, the bending angle of the straw becomes obtuse and the area to be sealed can be widened, and since the straw does not have an acute angle, the load on the straw that is repeatedly bent by opening and closing the lid can be reduced. Can be done.

The beverage container stopper may further include a sliding resistance portion provided between the hinge and the lid. When the lid is opened by the restoring force of the straw, the sliding resistance portion does not give sliding resistance to the rotation of the lid in the first opening range from the closed position to exceeding 90 degrees, and the first In the second opening range until the opening is fully opened beyond the opening range, the lid is provided so as to give sliding resistance to the rotation of the lid. The restoring force of the straw is set to the force that causes the lid to reach the second opening range from the closed position, and the sliding resistance is the sliding resistance of the lid from the second opening range to the first opening due to the weight of the lid. It is preferable to set the size so that it does not move to the range. As a result, when the lid is opened to the second opening range by the restoring force of the straw, the lid can be kept open.

In the above-mentioned beverage container stopper, a step portion may be provided on the upper surface of the stopper body on the side opposite to the hinge from the protruding position of the straw. The stepped portion is the first step portion proximal to the protruding position and above the protruding position, the second step portion distal to the protruding position and located above the first step portion, and the first step portion. It has an inclined portion provided between the step portion and the second step portion, and a ventilation hole is provided at a position close to the inclined portion in the first step portion, and when the lid is closed, the elastically deformed straw is provided. It is advisable to continuously adhere from the inclined portion to at least the ventilation hole. As a result, while reducing the burden of bending the straw, the bent portion of the straw can be brought into close contact with the stepped portion in a wide range, and the ventilation holes can be appropriately sealed.

In the beverage container stopper, it is preferable that the peripheral region of the ventilation hole in the first stage portion is provided so as to project from a region other than the peripheral region. As a result, when the ventilation hole is sealed at the bent portion of the straw, the peripheral region of the ventilation hole can be easily brought into close contact with the straw, and the sealing of the ventilation hole can be improved. In addition, the peripheral area of the vent makes it easier to concentrate the pressure when blocking the passage of the straw.

In the beverage container stopper, it is preferable that the straw is provided with an asymmetrical flange portion and the stopper body is provided with a recess into which the flange portion is fitted. As a result, the straw can be attached to the stopper body in an appropriate direction by fitting the flange portion into the recess.

In the above-mentioned stopper for a beverage container, the operation portion is urged outward in the radial direction, and the lid is slightly opened in a raised position by pushing the operation portion inward in the radial direction while the lid is closed. The lid may be provided so as to be fully opened by releasing the pushing of the operation unit while the lid is temporarily stopped at the lifted position. As a result, when the lid is opened, it opens from the closed state to the raised position and temporarily stops, whereby the internal pressure of the container body can be reduced.

In the beverage container stopper, the lid has an engaging portion, and the operating portion has a first portion extending in the vertical direction and a second portion extending radially inward from the central portion of the first portion. A portion, an upper claw portion provided above the first portion and extending inward in the radial direction, and a lower claw portion provided between the upper claw portion and the second portion and extending outward in the radial direction. It may have a claw portion. In this beverage container stopper, when the lid is closed and the operating portion is urged outward in the radial direction, the engaging portion and the lower claw portion are engaged and the lid is closed. When the operation part is pushed inward in the radial direction, the engagement part and the lower claw part are disengaged, and then the engagement part and the upper claw part are engaged, and the lid is temporarily stopped at the raised position, and the lid body is stopped. When the push-in of the operation portion is released while the lid is temporarily stopped at the lifted position, the engagement portion and the upper claw portion are disengaged and the lid is fully opened. As a result, the position of engagement with the engaging part of the lid is performed step by step using the positional relationship between the upper claw and the lower claw, and the operation of pushing and releasing the operation part of the lid causes the lid to be engaged. It is possible to perform a temporary stop operation at the floating position and a fully open operation.

In the beverage container stopper, the radial advance / retreat operation of the operation portion is preferably guided by the upper surface of the lower claw portion and the lower surface of the second portion. As a result, the movement of the operating portion in the radial direction can be stabilized, and the lower claw portion and the second portion can also be used as a guide, so that the mechanism can be simplified.

In the above-mentioned beverage container stopper, the second portion has an elongated hole extending in the radial direction, and the operating portion is supported radially with respect to the stopper body by a pin inserted in the elongated hole. Is preferable. This enhances the operational stability of the operation unit.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same members are designated by the same reference numerals, and the description of the members once described will be omitted as appropriate.

(Composition of beverage container)
FIG. 1 is a perspective view illustrating the configuration of a beverage container according to the present embodiment.
2 (a) and 2 (b) are perspective views illustrating the beverage container stopper according to the present embodiment.
FIG. 2A shows a state in which the lid 30 is slightly open, and FIG. 2B shows a state in which the lid 30 is fully open.

The beverage container 100 according to the present embodiment includes a tubular container body 2 having an opening 2a at the top and a beverage container stopper 1 attached to the opening 2a of the container body 2. The container body 2 has, for example, a double structure made of stainless steel (for example, a vacuum heat insulating structure), and is configured in a tubular shape having a closed bottom and an opening 2a at the top. Beverages are stored in the container body 2 through the opening 2a with the beverage container plug 1 removed from the container body 2. If the container body 2 has a vacuum heat insulating structure, it is possible to improve the cold and heat insulating performance of the contained beverage.

In the present embodiment, the direction along the central axis of the cylinder in the container body 2 is the vertical direction, the side of the opening 2a of the container body 2 is the upper side (or the top), and the bottom side of the container body 2 (opposite to the opening 2a). The side) will be described as the lower side (or the lower side), the side far from the central axis in the radial direction of the cylinder in the container body 2 will be described as the outside, and the side closer to the center axis will be described as the inside. Further, the radial direction of the stopper body 10 described later is the same as the radial direction of the cylinder in the container body 2.

(Structure of stopper for beverage container)
The beverage container plug 1 includes a plug body 10 attached to the opening 2a of the container body 2, a straw 20 penetrating the plug body 10, a lid 30 that can be opened and closed from the plug body 10, and a lid 30. The operation unit 40 for opening operation and the slide unit 50 for locking and unlocking are provided.

The stopper body 10 has an annular body 11 attached to a position around the opening 2a of the container body 2 and an upper surface portion 12 provided on the upper side of the annular body 11. The stopper body 10 is formed of, for example, resin. The annular body 11 is screwed around the opening 2a of the container body 2 by, for example, a screw portion provided on the upper part of the container body 2. The method of attaching the annular body 11 to the container main body 2 may be fitting other than screwing, or may be attached to the container main body 2 via another member (may be attached with an intermediate member interposed therebetween. ).

The upper surface portion 12 is provided so as to cover the upper side of the annular body 11. The upper surface portion 12 is provided with a straw hole 20h through which the straw 20 penetrates to the inside of the container body 2. Further, the upper surface portion 12 is provided with a ventilation hole 10h for communicating the inside and the outside of the container main body 2. The diameter of the ventilation holes 10h is about 0.5 mm (millimeters) to about 1.5 mm, preferably about 1.0 mm.

The straw 20 is held by the plug body 10 in a state of penetrating the straw hole 20h provided in the upper surface portion 12 of the plug body 10. At least a portion (drinking mouth portion 21) of the straw 20 protruding upward from the stopper body 10 is provided with an elastically deformable material. Examples of the elastically deformable material are silicone resins. The straw 20 penetrating the stopper body 10 is provided up to the vicinity of the bottom of the container body 2.

For example, the upper surface portion 12 of the stopper body 10 is provided with a hinge 30a that serves as an axis for the rotational operation of the lid body 30. The lid 30 is urged in the opening direction by the restoring force when the drinking spout portion 21 of the straw 20 is elastically deformed. That is, in the present embodiment, it is not necessary to provide a separate spring on the lid body 30, and the restoring force of the straw 20 gives a force to open the lid body 30.

The operation unit 40 is provided so as to be able to move forward and backward in the radial direction of the plug body 10. That is, the operation unit 40 is not a swing type but a push button type. The lid 30 can be started to open by pushing the operation unit 40 inward in the radial direction while the lid 30 is closed. The operation unit 40 is urged outward in the radial direction by a spring 45 (see FIG. 3) incorporated between the operation unit 40 and the plug main body 10. Therefore, when the finger pushing the operation unit 40 is released (released), the operation unit 40 is returned to the outside by the urging force of the spring 45.

The slide unit 50 is a locking mechanism for locking and unlocking the operation by the operation unit 40. The slide portion 50 is placed on the outside of the operation portion 40 and is provided so as to be slidable in the vertical direction along the operation portion 40. The outer shape of the slide unit 50 is almost the same as the outer shape of the operation unit 40, and is slightly shorter in the vertical direction. By making the outer shape equivalent, it is possible to obtain a sense of unity in appearance between the slide unit 50 and the operation unit 40.

For example, when the slide unit 50 is slid downward, the lock state is set, and the pushing operation of the operation unit 40 can be prohibited. On the other hand, when the slide unit 50 is slid upward, for example, it becomes an unlocked state, and the pushing operation of the operation unit 40 can be permitted. The relationship between the vertical position of the slide portion 50 and the lock and unlock may be the reverse of the above. In the present embodiment, the slide portion 50 will be described as a locked state when the slide portion 50 is lowered, and an unlocked state when the slide portion 50 is turned up.

(Operation of slide part and operation part)
3A and 3B are cross-sectional views illustrating the operation of the slide unit and the operation unit.
FIG. 3A shows a locked state, and FIG. 3B shows an unlocked state.
4 (a) and 4 (b) are perspective views illustrating the configuration of the slide portion and the operation portion.
FIG. 4A shows an exploded perspective view, and FIG. 4B shows a perspective view of the slide unit 50 and the operation unit 40.

The operation unit 40 has a claw that engages with a first portion 41 extending in the vertical direction, a second portion 42 extending radially inward from the central portion of the first portion, and an engaging portion of the lid 30. It has a portion 43. The second portion 42 is provided with an elongated hole 42h extending in the radial direction, and the operating portion 40 is supported radially with respect to the plug body 10 by a pin 10p inserted into the elongated hole 42h. ..

A spring 45 is incorporated between the second portion 42 of the operation unit 40 and the plug body 10. The spring 45 urges the operating portion 40 outward in the radial direction. The position of the operating portion 40 toward the outside is restricted by the pin 10p coming into contact with the end of the elongated hole 42h. Since the movement of the operation unit 40 near the center is guided in the extending direction of the long hole 42h by the long hole 42h and the pin 10p, the forward / backward movement of the operation unit 40 in the radial direction is stable.

The slide portion 50 is placed on the outside of the first portion 41 of the operation portion 40. The slide portion 50 is provided with a pair of protruding pieces 50a, and the pair of protruding pieces 50a are fitted so as to hold the first portion 41 of the operating portion 40. A recess 41a is provided in the vertical direction at a position where the protruding piece 50a of the first portion 41 is fitted, and the protruding piece 50a can move within the range of the vertical length of the recess 41a. As a result, the slide portion 50 can slide in the vertical direction outside the first portion 41 of the operation portion 40. It should be noted that the upper position (unlock position) and the lower position (lock position) of the slide portion 50 may be fixed by giving a feeling of resistance at a predetermined position in the vertical movement of the slide portion 50.

With the operation unit 40 and the slide unit 50 assembled to the plug body 10, the convex portion 10a is provided at a position facing the protruding piece 50a of the slide unit 50 in the plug body 10. The convex portion 10a faces the protruding piece 50a only when the slide portion 50 is in the lower position (lock position), and does not face the protruding piece 50a when the slide portion 50 is in the upper position (unlocked position). It has become. Therefore, when the operation unit 40 is pushed together with the slide portion 50 with the slide portion 50 in the lower position, the protruding piece 50a hits the convex portion 10a and the pushing operation can be prevented (locked state). On the other hand, when the operation unit 40 is pushed together with the slide portion 50 with the slide portion 50 in the upper position, the protruding piece 50a does not hit the convex portion 10a and the pushing operation becomes possible (unlocked state).

As described above, in the present embodiment, the slide unit 50 is placed on the outside of the operation unit 40, and the operation unit 40 and the slide unit 50 can move forward and backward together in the radial direction, so that the operation unit 40 and the slide unit 50 can move forward and backward together. No protrusion during operation. Further, since the operation buttons for the lock / unlock and the opening operation of the lid 30 are integrally configured in appearance, the configuration can be simplified and the appearance can be simplified.

(Straw condition)
5 (a) and 5 (b) are cross-sectional views illustrating a state of a straw.
FIG. 5A shows a state in which the lid 30 is open, and FIG. 5B shows a state in which the lid 30 is closed.
The straw 20 is inserted into a spout portion 21 protruding upward from the plug body 10, an insertion portion 22 inserted into the container body 2 through a straw hole 20h provided in the upper surface portion 12 of the plug body 10, and a spout portion 21. It has a flange portion 23 provided between the portion 22 and the portion 22.

As shown in FIG. 5A, the drinking spout portion 21 of the straw 20 stands up when the lid 30 is open. The drinking spout portion 21 is provided with an angle in advance so that the tip thereof faces the side opposite to the hinge 30a in the vertical direction. This makes it easier for the user to hold the drinking mouth portion 21 of the straw 20 with his or her mouth.

The flange portion 23 is a stopper portion for preventing the straw 20 from coming off when the straw 20 is passed through the straw hole 20h from the lower side of the stopper body 10. The outer shape of the flange portion 23 is asymmetric when viewed in the vertical direction. A recess 15 corresponding to the outer shape of the flange portion 23 is provided at a position corresponding to the flange portion 23 of the plug main body 10.

The position of the straw 20 is fixed by fitting the flange portion 23 into the recess 15. At this time, since the flange portion 23 has an asymmetrical shape, the drinking port portion 21 of the straw 20 can be attached in an appropriate direction (so that it faces the side opposite to the hinge 30a).

The straw 20 can be removed from the stopper body 10 when cleaning the beverage container 100. In the present embodiment, since the lid 30 is opened by utilizing the restoring force of the straw 20, the orientation of the drinking spout portion 21 of the straw 20 is important. When the removed straw 20 is reattached, the flange portion 23 is fitted into the recess 15 at a fixed position, so that the direction of the drinking spout portion 21 of the straw 20 is not mistaken and the straw 20 is always attached in an appropriate direction. It becomes possible.

The upper surface portion 12 of the plug main body 10 is provided with a step portion 120 on the side opposite to the hinge 30a from the protruding position 12a of the straw 20. The step portion 120 is located proximal to the protrusion position 12a of the straw 20 and above the protrusion position 12a, and distal to the protrusion position 12a and above the first step portion 121. It has a second step portion 122 and an inclined portion 123 provided between the first step portion 121 and the second step portion 122.

A space is provided below the first stage portion 121. By providing this space, when the stopper main body 10 is molded with resin, it is possible to suppress the occurrence of sink marks on the first stage portion 121 during molding. The second portion 42 of the operation portion 40 is inserted into the space below the second stage portion 122 and the inclined portion 123, and the spring 45 is incorporated.

As shown in FIG. 5B, when the lid 30 is closed, the straw 20 is pushed down by the protruding portion 31 provided on the lid 30, and the straw is pushed down between the lid 30 and the upper surface portion 12 of the stopper body 10. 20 is stored in a state of being elastically deformed and bent. At this time, the side surface 20a on the side opposite to the protruding portion 31 of the straw 20 comes into continuous contact with the inclined portion 123 of the step portion 120 to at least the ventilation hole 10h. As a result, the bent portion of the straw 20 can be brought into close contact with the step portion 120 in a wide range, and the ventilation hole 10h can be appropriately sealed. Further, since the ventilation hole 10h is sealed on the side surface 20a of the straw 20 when the lid 30 is closed, it is not necessary to provide a separate mechanism for sealing the ventilation hole 10h, and the device configuration should be simplified. Can be done.

Further, the protruding portion 31 is provided at a position facing the ventilation hole 10h when the lid 30 is closed. Therefore, when the lid 30 is closed, the straw 20 is sandwiched between the protruding portion 31 and the first stage portion 121, and the passage of the straw 20 is blocked.

The ventilation hole 10h is provided at a position close to the inclined portion 123 in the first step portion 121. As a result, the ventilation hole 10h can be arranged near the center of the concave portion of the stepped portion 120 composed of the inclined portion 123 and the first stepped portion 121, and the side surface 20a of the straw 20 can be made convex and brought into close contact with the straw 20. can.

Further, it is preferable that the peripheral region of the ventilation hole 10h in the first step portion 121 slightly protrudes from the region other than the peripheral region. As a result, when the ventilation hole 10h is sealed at the bent portion of the straw 20, the peripheral region of the ventilation hole 10h can be easily brought into close contact with the straw 20, and the airtightness of the ventilation hole 10h can be improved. In addition, it becomes easier to concentrate the pressure when blocking the passage of the straw 20.

(Straw condition)
FIG. 6 is a cross-sectional view illustrating the state of the straw when the lid is closed.
In the present embodiment, when the lid 30 is closed, the passage of the straw 20 is blocked by the protruding portion 31 of the lid 30, and the ventilation hole 10h is sealed by the side surface 20a on the side opposite to the protruding portion 31 of the straw 20. Is done. At this time, the side surface 20a of the straw 20 opposite to the protruding portion 31 is bent at an obtuse angle.

Here, the obtuse angle of the side surface 20a of the straw 20 means that in the curved straw 20, the position of the side surface 20a opposite to the position where the protrusion 31 contacts is point B (see FIG. 5), and the straw is relative to the point B. The support point (or inflection point) on one side of the side surface 20a of 20 is point A (see FIG. 5), and the support point (or inflection point) on the other side of the side surface 20a of the straw 20 is point C with respect to point B. (See FIG. 5) means that the inflection angle of ∠ABC (see FIG. 5) is obtuse. When the straw 20 is curved, the ventilation hole 10h is closed around the point B of the side surface 20a.

In this way, the side surface 20a of the bent straw 20 has an obtuse angle, so that the side surface 20a of the straw 20 can easily adhere to each other in a wide range along the step portion 120, and the airtightness of the ventilation hole 10h can be improved. Can be done. Further, since the straw 20 does not have an acute angle when it is bent, it is possible to make it difficult for the straw 20 to bend and to reduce the load on the straw 20 which is repeatedly bent by opening and closing the lid 30. It is possible to increase the durability of the.

(Engagement of operation part and lid)
In the beverage container plug 1 according to the present embodiment, the lid 30 has an engaging portion 32 provided on the side opposite to the hinge 30a. The engaging portion 32 is a rod-shaped member provided at the edge portion of the annular body 11. The claw portion 43, which is the counterpart to engage with the engaging portion 32, is provided in the operation portion 40. The claw portion 43 has an upper claw portion 431 and a lower claw portion 432.

The upper claw portion 431 is provided on the upper side of the first portion 41 and extends inward in the radial direction. The lower claw portion 432 is provided between the upper claw portion 431 and the second portion 42 and extends outward in the radial direction. That is, the upper claw portion 431 and the lower claw portion 432 are provided so as to face each other in a stepped manner. The engaging portion 32 of the lid 30 engages with either the upper claw portion 431 or the lower claw portion 432 according to the rotation angle of the lid 30.

Utilizing the positional relationship between the upper claw portion 431 and the lower claw portion 432, the engagement position of the lid 30 with the engaging portion 32 is stepwise performed, and the pushing operation of the operating portion 40 and the disengaging operation are performed. By the (returning) operation, the opening operation of the lid 30 can be temporarily stopped and the lid 30 can be fully opened. The details of the operation of the lid 30 will be described later.

Further, the movement of the operating portion 40 in the radial direction is guided by the upper surface of the lower claw portion 432 and the lower surface of the second portion 42. That is, the second portion 42 moves forward and backward in the radial direction in the space under the step portion 120, but at this time, the upper surface of the lower claw portion 432 and the lower surface of the second portion 42 are in the space under the step portion 120. Will slide in the radial direction. As a result, the radial advance / retreat operation of the operation unit 40 can be stabilized, and the lower claw portion 432 and the second portion 42 can also be used as a guide for the advance / retreat operation, so that the mechanism can be simplified.

(Opening operation of the lid)
Next, the opening operation of the lid 30 in the beverage container stopper 1 will be described.
7 to 10 are cross-sectional views illustrating the opening operation of the lid.
As shown in FIG. 7, when the lid 30 is closed (fully closed), the drinking spout portion 21 of the straw 20 is elastically deformed and bent between the lid 30 and the stopper body 10. Be sandwiched. As a result, the passage of the straw 20 is blocked by the protruding portion 31 of the lid 30, and the ventilation hole 10h is sealed by the side surface 20a of the straw 20 opposite to the protruding portion 31. Therefore, when the lid 30 is closed, the beverage contained in the container body 2 does not leak to the outside.

When the lid 30 is fully closed and the operating portion 40 is urged outward in the radial direction by the urging force of the spring 45, the lower claw portion 432 engages with the engaging portion 32 of the lid 30 and the lid. Maintain the fully closed state of the body 30. If the slide unit 50 is moved downward in this state, it becomes locked and the operation unit 40 cannot be pushed in. This makes it possible to prevent the operation unit 40 from being inadvertently pushed and the lid 30 from opening.

When the slide unit 50 is moved upward, it becomes unlocked and the operation unit 40 can be pushed in. As shown in FIG. 8, when the operation unit 40 is pushed inward in the radial direction together with the slide unit 50 in the unlocked state, the operation unit 40 overcomes the urging force of the spring 45 and moves inward. As a result, the lower claw portion 432 and the engaging portion 32 are disengaged, and the lid 30 begins to open due to the restoring force of the elastically deformed straw 20.

Here, at the position where the lid 30 is slightly opened, the upper claw portion 431 of the operation portion 40 and the engaging portion 32 are engaged with each other. That is, although the lower claw portion 432 and the engaging portion 32 are disengaged by pushing the operating portion 40 inward, the upper claw portion 431 and the engaging portion 32 that have moved inward together with the operating portion 40 are engaged. The opening operation of the lid 30 is temporarily stopped. The position where the opening operation of the lid 30 is temporarily stopped is referred to as the floating position of the lid 30.

FIG. 8 shows a state in which the lid 30 is temporarily stopped at the raised position. When the lid 30 is in the raised position, the ventilation hole 10h blocked by the side surface 20a of the straw 20 is opened, and the passage of the straw 20 blocked by the protruding portion 31 of the lid 30 is also opened. .. As a result, when the internal pressure of the container body 2 is higher than the external pressure, air is evacuated from the ventilation holes 10h, and the internal pressure of the container body 2 can be lowered. Further, even when the internal pressure of the passage of the straw 20 is higher than the external pressure, the air is evacuated by opening the passage of the straw 20.

When the air is evacuated from the ventilation holes 10h and the straw 20, the lid 30 is stopped at the raised position, so that it is possible to prevent the beverage from being ejected from the ventilation holes 10h and the straw 20 and hitting the user. Can be done.

Here, in a configuration in which the lid 30 is opened by using the restoring force of the straw 20, it is desired to use the straw 20 having a strong restoring force as much as possible. However, the stronger the restoring force, the stronger the force to open the lid 30, but the stronger the rebound of the straw 20. If the lid 30 is not provided with a mechanism for temporarily stopping at the raised position, the lid 30 opens at once and the straw 20 also jumps up vigorously, and if the beverage is scattered or the internal pressure is high, the straw 20 is used. Air bleeding occurs suddenly, which may lead to the spouting of beverages.

If the lid 30 is temporarily stopped at the raised position as in the present embodiment, it is possible to effectively prevent the beverage from splashing or spouting even if the straw 20 having a strong restoring force is used.

Further, as described above, in the present embodiment, since the bending angle of the straw 20 is an obtuse angle, the upward angle of the drinking spout portion 21 tends to be low. Therefore, it is preferable that at least the opening of the drinking spout portion 21 is hidden inside the lid 30 with the lid 30 temporarily stopped at the raised position.

That is, at the raised position of the lid 30, (1) the sealing of the ventilation hole 10h by the straw 20 is released, (2) the obstruction of the passage of the straw 20 by the protruding portion 31 is released, and (3) drinking. It is preferable that the angle (position) satisfies that at least the opening (the tip of the passage of the straw 20) of the mouth portion 21 is hidden inside the lid 30. As a result, even if the air is evacuated at the floating position and the beverage is ejected from the straw 20, it can be prevented from bouncing back on the inside (back side) of the lid 30 and jumping out to the outside (user side).

Next, as shown in FIG. 9, the pushing of the operating portion 40 that had been pushed together with the sliding portion 50 is released (the finger is released). As a result, the operation unit 40 is moved (pushed back) to the outside by the urging force of the spring 45. As the operating portion 40 moves outward, the engagement between the upper claw portion 431 and the engaging portion 32 is disengaged, and the lid 30 starts to open again due to the restoring force of the straw 20.

Then, as shown in FIG. 10, the lid 30 is vigorously opened by the restoring force of the straw 20 and reaches the fully opened position. In the operation of opening the lid body 30, it is preferable to change the sliding resistance by a predetermined opening degree of the lid body 30. In the present embodiment, the sliding resistance portion 60 is provided between the hinge 30a and the lid 30. The sliding resistance portion 60 has a protruding piece 61 provided on the back side of the lid 30 and a convex portion 62 provided on the hinge 30a.

When the lid 30 is opened by the restoring force of the straw 20, the sliding resistance portion 60 is the lid 30 in the first opening range (see P1 in FIG. 10) from the closed position until the lid 30 exceeds 90 degrees. No sliding resistance is given to the rotation, and sliding resistance is applied to the rotation of the lid 30 in the second opening range (see P1 to P2 in FIG. 10) until the first opening range P1 is exceeded and the lid is fully opened. Provided to give.

That is, the protruding piece 61 and the convex portion 62 do not come into contact with each other until the lid 30 reaches the first opening range P1 from the closed position, and the protruding piece 61 and the convex portion 62 are not in contact with each other from the position beyond the first opening range P1. Contact with and increases sliding resistance. The contact between the projecting piece 61 and the convex portion 62 may be performed in the entire area of the second opening range P2, or may be performed in a part of the second opening range P2.

The magnitude of the sliding resistance generated in the sliding resistance portion 60 may be set so that the lid body 30 does not move from the second opening range P2 to the first opening range P1 due to the weight of the lid 30. preferable. As a result, the lid 30 opened to the second opening range P2 does not close due to its own weight, so that it is possible to prevent the lid 30 from closing naturally even if the beverage container 100 is tilted when drinking a beverage. be able to.

Further, the restoring force of the straw 20 may be set to a force that allows the lid body 30 to reach the second opening range P2 from the closed position at once even if the sliding resistance increase in the sliding resistance portion 60 functions. preferable. As a result, when the lid 30 is opened by the restoring force of the straw 20, the lid 30 can be opened at once beyond the first opening range P1 to the second opening range P2.

When closing the lid 30, the lid 30 is closed by hand. When the lid 30 enters the first opening range P1 from the second opening range P2, it can be easily closed without sliding resistance due to the sliding resistance portion 60. Further, when the lid 30 hits the straw 20 and then closes further, the straw 20 is naturally bent by the elastic deformation of the straw 20, and the ventilation holes 10h are sealed and the straw 20 is closed. Then, by closing the engaging portion 32 until it engages with the lower claw portion 432, the fully closed state of the lid 30 is maintained.

As described above, according to the present embodiment, it is possible to improve the operability, simplify the structure, and improve the durability of the straw 20 in the beverage container stopper 1 and the beverage container 100 provided with the straw 20. become.
