Description

  The present invention relates to an improvement in a straw-type beverage container with a lid for containing beverages such as milk and fruit juice.

2. Description of the Related Art Conventionally, for example, as a beverage container for infants and the like to drink beverages such as milk, fruit juice, and tea, a beverage container with a drinking straw is used. Some of such beverage containers can be sucked with a straw for drinking, and when not in use, the straw can be folded to close the lid.
Here, when warm milk or the like is put in such a beverage container, the lid is closed and the straw is sealed, the inside of the container becomes positive pressure, and when the infant or the like actually drinks, the lid is opened and the straw is opened at the same time. If it is in a state, warm milk or the like may be ejected from the straw.
Therefore, conventionally, such a beverage container has a structure in which a vent hole is formed to release the internal pressure to prevent milk or the like from being ejected from the straw.

Further, such a vent is provided with a movable cover and a check valve so that the beverage in the container does not leak out.
However, the conventional beverage containers provided with the vent holes and the movable cover as described above mainly have the following problems.

  When the movable cover is opened, the vents are opened, and the vents are opened when drinking. Therefore, even if the user drinks, there is an advantage that the inside of the container is not negative and easy to drink. When the container is tilted with the cover open, there is a problem that the beverage leaks from the vent hole.

Therefore, the present applicant, when the user drinks the beverage in the container body at the drinking port such as a straw, even if the container body is tilted, the beverage does not leak out, and the inside of the container body has a negative pressure or the like. As a beverage container that can prevent the beverage from becoming difficult to drink, the beverage container of Patent Document 1 is proposed.
As shown in FIG. 2 of Patent Document 1, this beverage container is a container body 11, a dome-shaped base member 12, and a lid that slides on the base member 12 along the outer shape of the base member 12. And a slide lid 15. The base member 12 includes a first ventilation portion 18 that adjusts a pressure change in the container body 11 and a second ventilation portion 17 that is a vent hole with a check valve. The slide lid 15 includes a first ventilation portion. Ventilation opening / closing means 15a and the like that can change 18 to a ventilation state or a closed state are formed. The ventilation opening / closing means allows the first ventilation portion 18 to be used in a portable state where the user can carry the beverage container (see FIG. 5) and a drinking state where the drinking mouth portion can be used by the user (see FIG. 2). Set to blocked status. In the operation state of FIG. 4, the first ventilation portion 18 is in a ventilation state.

Thereby, the state in which the slide lid 15 which is the lid is closed and carried, and the second ventilation portion 17 which is the vent hole with a check valve of the beverage container is closed by the ventilation opening / closing means 15a. The liquid beverage accommodated therein does not leak out from the second ventilation portion 17, and the liquid beverage does not leak out from the first ventilation portion 18 that is an opening-shaped ventilation hole.
Moreover, when arrange | positioning in the operation state which is the intermediate position which moves so that the slide cover 15 may be opened for drinking, the 1st ventilation part 18 will be in the ventilation | gas_flowing state. For this reason, even when warm milk or the like is accommodated in the container main body 11 and the pressure inside the container is positive with respect to the outside, the pressure is released to the atmosphere via the first ventilation portion 18.
When the slide lid 15 is further moved to increase the opening and is placed in a drinking state, the first ventilation portion 18 is closed, so that the user drinks the liquid drink inside by tilting the container body 11 from the mouth. However, the liquid drink inside does not leak from the first ventilation part 18. However, the second ventilation part 17 is formed in the base member 13.
For this reason, even if the user drinks the liquid beverage in the container main body 11 from the drinking mouth part, the internal volume decreases, and the inside of the container main body 11 becomes negative pressure, the check valve of the second ventilation part 17 opens, The outside air is guided into the container body 11 and the negative pressure state in the container body 11 is eliminated. Therefore, it is possible to prevent the occurrence of a situation in which the inside of the container main body 11 is in a negative pressure state and it becomes difficult for the user to drink the beverage from the drinking mouth portion.

WO2007 / 148441 (see FIG. 2 etc.)

In the beverage container with a straw of patent document 1, it has the base member 12 which has the arc-shaped upper surface which became convex upwards while closing the opening part of the container main body 11, and on the upper surface of this base member 12 The vent member 16 is formed so as to protrude to the outside.
Furthermore, the cross-section arc-shaped slide lid 15 slides on the arc-shaped upper surface of the base member to open and close the lid.
For this reason, the slide lid 15 and the upper end of the ventilation member 16 are always in contact with each other, and the upper end of the ventilation member 16 is worn by long-term use, and when the wear progresses, the possibility of liquid leakage is completely denied. I can't.

  The present invention has been made to solve the above problems, and improves durability, avoids damage to the ventilation member even when the lid opening / closing member is repeatedly operated, and effectively prevents liquid leakage. An object is to provide a beverage container that can be used.

  The present invention is a beverage having a container body that contains a liquid beverage and has a container opening for containing the liquid beverage, and a base member that covers the container opening and includes a straw that is elastically deformable as a drinking mouth. A slide having a curved surface that is convex toward the outside, wherein the base member has a curved surface that is convex outward, and slides on the curved surface of the base member and moves. A lid, and a tip of the slide lid comes into contact with an intermediate position in the length direction of the straw, and a support wall erected on the base member on the opposite side of the straw at the intermediate position. The straw is supported, and the slide lid is further slid in the closing direction from the contact position so that the straw is bent at the support position while being supported by the support wall. The base member is formed so that a ventilation member is exposed on the inner side of the slide lid, and the ventilation member is formed so as not to leak liquid from the straw. The container main body communicates with the outside, and a first ventilation portion that adjusts the pressure change in the main body, and when the inside of the container main body is in a negative pressure state with respect to the outside, introduces air from the outside, A second ventilation portion that can prevent leakage of the liquid beverage in the container body, and a carrying position for closing and closing the straw so that a user can carry the container by sliding movement of the slide lid In the drinking position where the slide lid is moved and arranged until the straw is exposed and extended so that the straw can be released and used, the first ventilation portion is closed, and the carrying position In the operation state in which the slide lid is moved and arranged at the middle position of the drinking position, the first ventilation portion is configured to be in a ventilation state, and the slide lid is completely opened at the drinking position. In this state, the tip of the slide lid does not substantially contact the straw, and when the slide lid slides from the drinking position, the vicinity of the tip of the slide lid comes into contact with the straw and bends the straw. A state in which the slide lid is deformed by riding on it and pushed up by the elastic force of the straw so that the proximal end side of the slide lid is separated from the ventilation member and is slid until the slide lid is completely closed. Then, since the force is applied so that the elastic force of the straw is pushed up from the bottom to the tip of the slide lid, the straw is abutted and supported from below. The base end side of the slide lid is biased downward with the distal end of the supporting wall as a fulcrum, so that it comes into contact with the ventilation member.

According to the above configuration, when in the operating position other than the drinking position, the ventilation member is opened by the seesaw principle using the elastic force of the straw, and the container body is filled with, for example, a high temperature beverage or carbonic acid. Since the positive pressure based on the accommodation of the beverage or the like is adjusted by being released to the atmosphere, the ejection of the beverage from the straw can be effectively prevented.
In the position where the slide lid is completely closed, a force is applied so that the elastic force of the straw is pushed up from the bottom against the tip of the slide lid. Since the base end side of the slide lid is biased downward with the support wall tip as a fulcrum, the base end side of the slide lid contacts the ventilation member based on the principle of this “seesaw”. Leakage can be effectively prevented.
In this way, in the operation position other than the drinking position and the closing position, the slide lid hardly contacts or rubs the ventilation member, and the wear of the ventilation member can be effectively prevented and used for a long time. No liquid leakage.

Preferably, the base member is provided with the ventilation member at a position close to a base end side of a slit that is opened and closed by the sliding movement of the slide lid with respect to a center of the curved surface of the base member. The ventilation member has an inclined surface with an upper end inclined toward the base end side, and the outer openings of the first ventilation portion and the second ventilation portion are exposed on the inclined surface. It is characterized by.
According to the above configuration, the slide lid that bends the straw and rides on the slide lid uses the elasticity of the straw as a power point based on the principle of “seesaw”, and the base end side of the slide lid is Since the ventilation member can be brought into contact with and separated from the ventilation member, and the ventilation member has an inclined surface having a gradient that decreases toward the base end side, friction in movement of the slide lid hardly occurs.

Preferably, the outer openings of the first ventilation part and the second ventilation part are formed so as to slightly protrude from the inclined surface, and the inner surface of the slide lid is formed on the inner surface of the slide lid at the drinking position. The function of the second ventilation part is brought into contact with only the first ventilation part, and the function of the second ventilation part is exhibited by opening the ventilation member in the operation position, and the function is performed in the carrying position. The ventilation member includes a plurality of protrusion-shaped ventilation opening / closing portions that respectively contact the ventilation portions of the first ventilation portion and the second ventilation portion of the ventilation member.
According to the above configuration, it is possible to prevent the beverage from being ejected from the straw only by sliding the slide lid, to adjust the inside of the container body to atmospheric pressure when drinking, and to allow liquid leakage when carried. Can be obtained.

Preferably, the slide lid is a curved belt-like member, and protrusions or slide ribs provided on both side edges in the width direction of the belt-like slide lid are formed at both sides in the width direction of the belt-like opening formed in the base member. , And is configured to be slid and supported by a protrusion or slide groove formed along the slide direction.
According to the said structure, compared with the structure which a cover body rotates by a hinge etc. and opens and closes, a clearance gap does not arise in a bearing side surface etc., and there is no danger of pinching a finger | toe.

Preferably, the base member is mounted with a hood member in which a wide slit is formed corresponding to an area in which the slide lid slides, and the slide lid always moves in the wide slit. It is characterized by having a configuration.
According to the above configuration, since the slide lid always moves inside the hood member, unnecessary protrusions and protrusions are not exposed to the outside, and it may cause an unexpected injury or cause an erroneous operation. Absent.

Preferably, a finger hook protruding upward is formed on the top surface of the tip of the slide lid, and a protrusion or wall protruding downward is formed as a stopper at the base end of the slit of the hood member. In addition, the slide lid is formed with a stopper that protrudes upward on the base end side with respect to the finger hook.
According to the said structure, a slide lid can be easily operated in a closing direction using the said finger hook. In addition, when the slide lid is opened, the stopper of the slide wall abuts against the stopper of the hood member in the fully open state, which is the drinking position, and can be easily aligned with the drinking position.

  It is possible to provide a beverage container capable of improving durability, avoiding damage to the ventilation member even when the opening / closing member of the slide lid is repeatedly operated, and effectively preventing liquid leakage.

The support wall 22 is a support wall that bends the straw 20 at its upper end when the straw 20 is pressed by opening and closing the slide lid 15 described later.

A hood member 14 is attached to the base member 13 so as to cover it from above. The hood member 14 also has a substantially dome-shaped outer shape so that it can be disposed outside the base member 13 corresponding to the shape of the base member 13. The hood member 14 covers the base member 13 and is detachably attached by being screwed with a screw portion provided on the outer periphery of the container main body 11.
The base member 13 and the hood member 14 are respectively provided with slits 13a and 14a having a strip-shaped opening by removing the upper part into a strip shape having a curved upper portion. In the present embodiment, the slits 13a and 14a have such a size that the top portions of the dome shape of the base member 13 and the hood member 14 are cut out slightly larger than a half circumference.
The slits 13a and 14a are opened and closed by a slide lid 15 described later. The slide lid 15 has a shape and size that closes the slits 13a and 14a, and is a molded product such as a synthetic resin that can be elastically deformed to some extent. The configuration will be described in detail later.
Further, as shown in FIG. 6, the base member 13 is integrally formed with a bottomed cylindrical body extending in the depth direction, and accommodates this when the slide lid 15 is opened. It is set to 19.

A ring-shaped packing 31 and a handle 32 are interposed between the base member 13 and the container body 11 as a sealing member for liquid-tight sealing. And the drink container 10 is fixed by laminating | stacking the handle 32, packing 31, and the base member 13 on the upper end side of the container main body 11, and pinching these by the hood member 14. As shown in FIG.
In this case, the handle 32 can be attached and detached by fitting a ring-shaped main body 33 into the upper end portion of the container main body 11, and a pair of handle-shaped handles 34, 34 are attached to the ring-shaped main body 33. Is extended. The handle 32 has engagement pieces 33 a provided at two locations on the inner peripheral surface of the main body 33. The engaging piece 33a of the main body 33 is engaged with an engaging concave portion 11a provided at a corresponding position of the container main body 11, so that the handle 32 is fixed at a predetermined position and is not rotated.

The structure around the base member 13, the hood member 14, and the slide lid 15 will be described with reference to FIG. 1, FIG. 2, and FIG. FIG. 6 is a schematic cross-sectional view of the upper structure of the beverage container 10 cut along the line CC in FIG.
Slide grooves 13b are provided along both side portions on the inner side in the longitudinal direction of the slit 13a of the base member 13 (see FIG. 2). A slide lid 15 is slidably attached to the slide groove 13b.
FIG. 5 is a schematic perspective view of the periphery of the base end portion 15b of the slide lid 15 as seen from the back side. As shown in FIG. 5, for example, slide ribs 35, 35 are formed on the slide lid 15 as protrusions along both side edges that are both ends in the width direction.
By inserting the slide ribs 35 and 35 into the slide groove 13b of the base member 13, the slide lid 15 can slide along the groove direction, and the slit 13a of the base member 13 is opened and closed. Yes.

Further, in the vicinity of the base end portion 15b of the inner surface of the slide lid 15, projecting portions 36 and 37 that slightly protrude are formed in parallel. The protrusions 36 and 37 constitute a ventilation opening / closing part of the ventilation member 16 to be described later, and one protrusion 36 communicates the container main body 11 with the outside, and adjusts a pressure change in the main body 11. It is a first ventilation opening / closing part that contacts and closes one ventilation part, and the other protrusion 37 introduces air from the outside when the inside of the container body 11 is in a negative pressure state with respect to the outside, and the container body 11 It is the 2nd ventilation opening / closing part which contact | abuts and blocks the 2nd ventilation | gas_flowing part which can prevent the leakage of the inside liquid drink. Further, another protrusion 38 is formed along the longitudinal direction of the slide lid 15, that is, the position close to the distal end portion 15 a of FIG. 2, and the protrusion 38 opens and closes the first ventilation portion. To do.
The protrusions 36 to 38 formed on the inner surface of the slide lid 15 are formed in a shape slightly extended in the longitudinal direction as compared with the openings of the first ventilation portion 17 and the second ventilation portion 18 of the ventilation member 16 described later. Yes. This is to prevent liquid leakage when the user accidentally drinks or carries the slide lid 15 at the operation position immediately before reaching the drinking position and carrying position described later. It is.
Further, on the inner surface of the slide lid 15, a ridge or linear rib 39 is formed that extends along the slide movement direction and slightly protrudes in the thickness direction. Preferably, as shown in FIG. 5, a plurality of ridges 39 are formed in parallel, and exhibit an effect of reducing sliding resistance when the slide lid 15 slides on the folded straw 20. It has become.

In FIG. 6, the upper surface of the tip 15a of the slide lid 15 is a finger hook projecting upward.
Further, a stopper 14b, which is a protrusion protruding downward, is formed at the base end portion which is the back side of the slit 14a of the hood member 14, whereas the slide lid 15 has the above-described finger. A stopper 15c protruding upward is formed on the base end side of the hook.
For this reason, the slide lid 15 can be easily closed using the tip 15a that is a finger hook, and when the slide lid 15 is opened, it is in the drinking position shown in FIG. In the fully open state, the stopper 15c of the slide lid 15 abuts on the stopper 14b of the hood member 14, and can be easily aligned with the drinking position.

The ventilation member 16 will be described with reference to FIGS.
As shown in FIG. 3, the ventilation member 16 includes a first ventilation part 17 and a second ventilation part 18.
As shown in FIG. 2, the ventilation member 16 is disposed at a position closer to the proximal end side of the slit 13 a with respect to the center position of the curved surface 13 c (see FIG. 6) that is the upper surface of the base member 13. The ventilation member 16 has an inclined surface whose upper end is inclined toward the proximal end side of the slit 13a, and the outer openings of the first ventilation portion 17 and the second ventilation portion 18 are exposed on the inclined surface. ing. This will be specifically described below.

As shown in FIG. 3, the ventilation member 16 is made of a resin molded product, and includes a main body 41, and a first ventilation part 17 and a second ventilation part 18 that protrude downward in parallel from the main body 41. .
As shown in FIG. 4A, the first ventilation part 17 forms a tubular ventilation path extending along the vertical direction of the main body 41 of the ventilation member 16, and is always open. As shown in FIG. 4B, the second ventilation portion 18 is formed by forming a check valve at the lower end of a tubular ventilation path extending along the vertical direction of the main body 41 of the ventilation member 16. The valve body is closed so that the liquid in the container body 11 does not leak to the outside. However, when the inside of the container body 11 becomes negative pressure, the valve body is opened to bring the inside of the container body 11 to atmospheric pressure.
The upper surface of the main body 41 of the ventilation member 16 is an inclined surface 44 that gradually descends toward the front of the page in FIG. The inclined surface 44 communicates with the first ventilation portion 17 and has an upper end opened. The abutment portion 42 slightly protrudes upward, and communicates with the second ventilation portion 18 and has an upper end opened. A contact portion 43 that slightly protrudes upward is formed.

Next, the operation of this embodiment will be described with reference to FIGS.
FIG. 6 shows a state where the beverage container 10 can be used to drink a liquid beverage, and shows the drinking position of the slide lid 15.
7, 8, 9, and 10 show operation positions for performing an operation of sliding the slide lid 15 from the drinking position and closing it.
FIG. 11 shows a so-called carrying position where the slide lid 15 is completely closed and the mother or the like can carry it in a bag without leaking liquid.

(Drinking position)
When drinking the liquid beverage in the container body 11, the slide lid 15 is slid in the direction of arrow E as shown in FIG.
At this time, the stopper 15c near the tip of the slide lid 15 contacts the stopper 14b of the hood member 14 and does not open any further. At this position, since the groove width of the slide groove 13b ("see FIG. 2", the same applies hereinafter) is narrow and there is almost no play, the slide lid 15 is kept open without rattling. At this position, the protrusion 38 on the back surface of the slide lid 15 described with reference to FIG. 5 blocks the contact portion 42 of the first ventilation portion 17 of the ventilation member 16 attached to the base member 14 without rattling. In this position, the slide lid 15 does not contact the straw 20 at the tip 15a, and does not bend the straw 20 so as not to prevent drinking.
As a result, when the liquid beverage is sucked from the container body 11 of the beverage container 10 and the inside of the container body 11 becomes negative pressure (negative pressure), the check valve of the second ventilation portion 18 is opened and the container body 11 Since it is released to the atmosphere, it does not become difficult to suck liquid drinks. In addition, since the protrusion 38 of the slide lid 15 closes the first ventilation portion 17, liquid leakage due to the inclination of the container body 11 does not occur.

(Operation position)
Please refer to FIG.
FIG. 7 shows an initial position in the operation position of the beverage container 10 of FIG. 1, and the slide portion 15 is slid in the direction of arrow D with the tip 15 a of the slide lid 15 as a finger hook. As a result, the tip end 15a side of the slide lid 15 is drawn out from the slide groove 13b shown in FIG. At this time, the straw 20 is bent near the upper end of the support wall 22 because the abutted opposite side is supported by the support wall 22.
Then, the distal end portion 15a side of the slide lid 15 that has received the force to which the bent straw 20 returns is pushed up, and the protrusion 38 on the back surface of the slide lid 15 described with reference to FIG. 5 is attached to the base member 13. The ventilation member 16 is separated from the contact portion 42 of the first ventilation portion 17. That is, in the drinking position shown in FIG. 6, the slide lid 15 is in a position in contact with the curved surface 13 c of the base member 13, but by riding on the straw 20, the base member 13 corresponds to the approximate thickness of the straw 20. It is separated from the curved surface 13c. Thereby, the protrusion 38 of the slide lid 15 is separated from the abutting portion 42 of the first ventilation portion 17, and the inside of the container main body 11 communicates with the outside.

FIG. 8 shows an intermediate position of the operation position of the beverage container 10.
As shown in the drawing, when the slide lid 15 moves in the direction of the arrow D and completely rides on the straw 20, the slide lid 15 slides at a position away from the curved surface 13c of the base member 13. Become. At this time, the slide lid 15 is positioned on the distal end side of the slit 13 a of the base member 13 from the support wall 22 on the distal end portion 15 a side. Therefore, the straw 20 is bent by the support wall 22 and the slide lid 15.

FIG. 9 shows a stage where the rear end (base end side) of the slide lid 15 has moved onto the ventilation member 16 at the operation position of the beverage container 10. At this time, the slide lid 15 has not reached the carrying position, which is the position where the slit 13a of the base member 13 is completely closed, but the protrusions 36 and 37 on the back surface of the slide lid 15 are in the longitudinal direction of the slide lid 15, that is, Since it is formed by being stretched in the slide movement direction, it is located on the ventilation member 16.
The force of the user's finger is applied to the distal end portion 15a of the slide lid 15 as F1, and this force is based on the vicinity of the distal end of the support wall 22 and the base end portion 15b side of the slide lid 15 is the principle of the seesaw. Therefore, the protrusions 36 and 37 on the back surface of the slide lid 15 are not in contact with the contact portions 42 and 43 of the ventilation member 16. Thereby, the ventilation member 16 is hardly worn by the sliding movement of the slide lid 15, and is effectively prevented from being damaged. Further, the beverage container 10 has a shape in which the protrusions 36 and 37 on the back surface of the slide lid 15 are extended in the slide movement direction as compared with the contact portions 42 and 43, so that the slide lid 15 is erroneously placed immediately before the carrying position. Even when the operation position is stopped, the ventilation member 16 can be closed.

FIG. 10 shows a stage where the tip 15 a of the slide lid 15 contacts the hood member 14 at the operation position of the beverage container 10.
The slide lid 15 cannot move any more in the direction of the arrow D, and in this state, the protrusions 36 and 37 on the back surface of the slide lid 15 are located immediately above the ventilation member 16. However, as long as the user's finger is placed on the distal end portion 15a of the slide lid 15, the force F1 moves upward on the base end portion 15b side of the slide lid 15 according to the seesaw principle with the vicinity of the distal end of the support wall 22 as a fulcrum. Therefore, the protrusions 36 and 37 on the back surface of the slide lid 15 are not in contact with the contact portions 42 and 43 of the ventilation member 16.

(Carrying position)
Next, in FIG. 11, when the user's finger is separated from the distal end portion 15 a of the slide lid 15, the distal end portion 15 a of the slide lid 15 is moved upward so that the elastic force F <b> 2 that the distal end side of the straw 20 attempts to return is illustrated. Since the base end portion 15b side of the slide lid 15 is moved downward by the seesaw principle with the vicinity of the tip of the support wall 22 as a fulcrum, the contact portions 42 and 43 of the ventilation member 16 are The protrusions 36 and 37 on the rear surface of the slide lid 15 come into contact with each other, and the first ventilation part 17 and the second ventilation part 18 are simultaneously closed.
Thereby, the slide lid 15 can liquid-tightly seal the main body 11 of the beverage container, and there is no risk of liquid leakage even if it is carried.

  Note that if the tip 15a of the slide lid 15 is opened with a finger, the state immediately becomes the state shown in FIG. 10, so that the first ventilation portion 17 is opened and high temperature milk or the like is accommodated in the container body 11. Since the positive pressure due to the air is immediately released to the atmosphere, it is possible to effectively prevent a situation where hot milk is spouted from the straw 20.

  In the above-described embodiment, the slide lid 15 that bends the straw 20 and rides and slides on the straw 20 uses the elasticity of the straw as a power point using the principle of “seesaw” and uses the base end of the slide lid 15. The portion 15b side can be brought into contact with and separated from the ventilation member 16, and the ventilation member 16 has an inclined surface (see reference numeral 44 in FIG. 3) that is a gradient that descends toward the proximal end side of the slide lid 15. Therefore, it is difficult to generate friction in the movement of the slide lid 15.

In addition, by simply sliding the slide lid 15, it is possible to prevent the beverage from being blown out from the straw 20, and to adjust the inside of the container body 11 to atmospheric pressure when drinking, making it easy to drink, and beverage that does not leak when carried. The container 10 can be obtained.
The slide lid 15 is a curved belt-like member, and the slide ribs 35 provided on both side edges in the width direction of the belt-like slide lid 15 are in the width direction of the slit 13 a that is a belt-like opening formed in the base member 13. In both sides, the slide groove 13b formed along the slide direction is supported and slid. For this reason, compared with the structure which a cover body rotates by a hinge etc. and opens and closes, a clearance gap does not arise in a bearing side surface etc., and there is no danger of pinching a finger | toe.

  Furthermore, the slide lid 15 is supported by the slide groove 13b in the vicinity of the base end of the belt-like opening (slit 13a). However, the groove width of the slide groove 13b is the same as that of the slide rib 35 of the slide lid 15 except for the drinking position. It is formed larger than the thickness t (see FIG. 5). Therefore, the slide lid 15 can slide and bend the straw 20 and ride on the straw 20. In the process, the tip 15 a side of the slide lid 15 is moved by the elastic force of the straw 20 according to the principle of “seesaw”. Float up. When the slide lid 15 rides on the straw 20 and the tip of the slide lid 15 exceeds the support wall 22, the base end portion 15b side of the slide lid 15 is pushed downward, so that the ventilation member 16 can be blocked.

In this embodiment, the slide lid 15 always moves inside the hood member 14, so that unnecessary protrusions and protrusions are not exposed to the outside, and may cause an unexpected injury or cause an erroneous operation. There is nothing.
Further, a finger hook protruding upward is formed on the upper surface of the distal end portion 15a of the slide lid 15, and a protrusion or wall-like protrusion protruding downward is formed at the base end portion of the slit 14a of the hood member 14. A stopper 14b is formed, and the slide lid 15 is further formed with a stopper 15c that protrudes upward toward the base end side relative to the finger hook. For this reason, the slide lid 15 can be easily operated in the closing direction using a finger hook. Further, when the slide lid 15 is opened, the stopper 15c of the slide lid 15 abuts against the stopper 14b of the hood member 14 in the fully open state that is the drinking position, and can be easily aligned with the drinking position.

  The present invention is not limited to the embodiments described above. For example, the first ventilation part and the second ventilation part may be provided separately. In addition, the individual configurations of the above-described embodiments may be partly omitted or arbitrarily combined with other configurations not described.
