Description

  The present invention is attached to the mouth of a vacuum double-structured bottle so that it can be attached to and detached from the bottle. An air intake part that sucks in from the outside when the liquid flows out is also provided, and the lid that is hinged to the stopper and opens and closes the outer periphery of the stopper is closed. The lock member is automatically locked in the closed position, and the lock relates to a bottle intake structure that is released by a lock release operation.

  This bottle intake structure makes use of the excellent heat insulation and slimness of vacuum double bottles, making it convenient for simple pouring and direct drinking while being widely used as a portable heat insulation and cold insulation container. Various ideas have been provided (for example, see Patent Documents 1 to 5).

  In each of Patent Documents 1 to 5, in addition to the outflow part of the content liquid suitable for a small flow rate for pouring or directly drinking the content liquid, the outside air for smooth outflow of the content liquid at a small flow rate is sucked in outside air Adopting a stopper structure with an intake part that closes the outflow part and the intake part by a lid that is automatically locked in the closed position in the closed state, and opening the cover opens the outflow part and the intake part Yes.

  For this purpose, the stopper structure disclosed in Patent Document 1 is such that the bottom wall of the recessed portion provided in the inner stopper portion that fits in the mouth of the bottle is inclined toward the front portion, and the front portion that is the lowest position of the bottom wall is provided. The lid that opens and closes the outlet around the inner plug part by opening the inlet and the inlet port at the rearmost part, which is the highest position, has a lid plug part that fits into the recessed part in the closed state. The outer periphery of the stopper is covered with a seal cap made of a seal member, and in addition to sealing the gap between the upper end opening of the recessed portion when the lid is closed, the seal cap is floated from the bottom wall of the recessed portion of the seal cap. When the hollow projection is brought into contact with the outlet and the outlet is closed, the backup projection backed up by the bottom wall of the cap recess is brought into contact with the inlet to close the inlet, and the lid is closed. Automatically closed by lock member It can be unlocked by unlocking the lock member, but a sub-block function is added to prevent the lid from being opened by manually hooking the latch on the closed lid separately from the lock member. However, even if an inadvertent external force is applied to the lock member and the lock is released, the lid is prevented from opening.

  The stopper structures disclosed in Patent Documents 2, 4, and 5 are a cylindrical outflow portion having a diameter that is almost half of the mouth of the bottle on the top surface of the stopper attached around the outside of the bottle mouth, An air intake opening that is open at the rear position is provided, a lid that is hinged to the stopper to open and close the outer periphery of the stopper, a seal part that abuts the outflow end of the outflow part in a closed state, and the intake opening A closing seal portion is provided. The seal that closes the air intake is made of a hollow body with a base attached to the boss of the lid, and closes the air intake and closes the air in the closed state when the cover is closed and locked to the closed position. The lid is opened until it is removed from the locked position by the restoring force when the is released. As a result, even if the unlocking operation is released immediately after the unlocking operation, it is possible to prevent the lid from being locked in the closed position again and hindering the subsequent opening operation of the lid.

The stopper structure disclosed in Patent Document 3 is attached so that it can be attached to and detached from the inner periphery of the bottle mouth, and is provided with a stopper body portion provided with an outlet and an inlet on the bottom wall of the recessed portion, a stopper body portion and a bottle mouth. A water-stop member that stops water except for the outflow port and the intake port, and hinged to the plug body, opens and closes the outer periphery of the plug body, and fits into the recess of the plug body when closed In addition to the lid having the lid plug portion, the cap-shaped sealing member covering the lid plug portion is backed up by a protrusion provided on the bottom wall of the lid plug portion, and the outlet portion and the intake air of the plug body portion when the lid is closed An outflow portion seal portion and an air portion seal portion that abut against the portions and individually close them are provided.

The plug structure disclosed in Patent Document 4 is
Japanese Patent No. 3620042 Japanese Patent No. 3937428 Japanese Patent No. 4203912 JP 2007-30992 A JP 2008-142425 A

  However, the plug structure disclosed in Patent Document 1 has a large bulky cap portion that has a cap portion that fits into a large recessed portion that substantially corresponds to the inner periphery of the mouth of the bottle formed on the lid side. It is easy to get in the way of handling and use such as hand washing, wiping, and supply / drainage of the contents liquid, and the sealing cap on the large lid stopper part separates the recessed part of the inner stopper part, the outflow part, and the intake part. Since sealing is performed, a cost increase is caused by a seal cap in which silicon rubber is often used for food hygiene and durability. In addition, in order to securely seal the outflow part and the intake part from the same side with one seal member, the back-up intake port seal part without play and the floating outlet seal part without backup flowed over pressure. Since it is absorbed by the outlet seal portion, excessive compression deformation and restoration thereof are repeated at the outlet seal portion, which causes a problem of fatigue.

  In the plug structures disclosed in Patent Documents 2, 4, and 5, since the outflow portion and the intake portion are sealed by individual seal members provided on the lid, there is no problem as in the case of sealing with one seal member. Since the seal member that closes the upper end of the diameter outflow portion becomes large, it cannot be made too small and the cost is increased accordingly, and the seal portion that closes the intake port is a hollow protrusion that supports the base on the protrusion of the lid, and the lid Since the bulge deformation to the surroundings is added to the deformation when compressed from the protruding side by closing, the deformation is complicated and the closure is locked by the restoring force when released from the compressed state when the lid is unlocked Since the amount of compression when the lid is closed is set large in order to push it out of the position, fatigue tends to occur and the life is shortened.

  In the plug structure disclosed in Patent Document 3, in the same manner as that described in Patent Document 1, the inner surface of the lid fits with the recessed portion of the plug body, and the three-dimensional shape on the inner side of the lid is greatly bulky. There is a problem that the seal cap shared by the outflow part and the intake part overlaid thereon is large, and that it is necessary to adjust the crimping to work on both the outflow part and the intake part from the same side. In addition, the cost is high due to the large number of parts that require a water-stop member comparable to the cap seal.

  In the present invention, both the outflow portion and the intake portion are individually closed by a small seal member without the cover being stretched, and the seal member provided at the intake port portion pushes the cover out of the lock position when unlocked. It is an object of the present invention to provide a bottle intake structure capable of exhibiting an opening function with high durability.

In order to solve the above-mentioned problem, the bottle intake structure of the present invention is attached so that it can be attached to and detached from the mouth of the vacuum double-structured bottle, and flows out into the bottle to allow the content liquid to flow out and be used for pouring and direct drinking. An air intake part that allows air to be sucked in from the outside when the liquid content flows out through the bottle, and a lid that opens and closes the outer periphery of the stopper is closed. In the bottle intake structure that is also opened and closed through the seal member and is automatically locked in the closed position by the lock member in the closed state, and the lock is released by the unlocking operation, the intake portion has at least its lid An annular or cylindrical air port to the side is made of a sealing member, and the sealing state is accompanied by compression until the lid comes into contact with the lid before reaching the closed position where the lid is locked by the locking member. Closed, and with one characterized by providing as pushed open to a position outside the closed to be the lock the cover to restore the unlocking of the lid.

  In such a configuration, the stopper attached to the mouth of the vacuum double structure bottle is accompanied by the intake of outside air into the bottle through the intake part, while allowing the content liquid to smoothly flow out through the outflow part, In the closed state, both the outflow part and the intake part are closed by the lid locked in the closed position. The intake part is independent of the outflow part, and is at least an annular or cylindrical intake port protruding toward the lid side. When the lid is closed, when the lid is closed, the lid is brought into contact with the lid from the closed position before the lid is locked by the lock member, and is closed with a ring pressure or cylindrical compression to the closed position. Leakage and heat leakage can be prevented, and it is restored by unlocking the lid, and the lid is pushed out of the closed position locked by the locking means. Be released can be avoided by locking the lid again.

  The bottle air intake structure of the present invention is also attached to a bottle having a vacuum double structure so that it can be attached to and detached from the bottle. In addition, an air intake part that allows air to be sucked in from the outside when the content liquid flows out through the bottle is attached, and the cover that is hinged to the stopper and that opens and closes the outer periphery of the stopper is closed. In the bottle intake structure that opens and closes and is automatically locked in the closed position by the lock member in the closed state, and the lock is released by the unlocking operation, the outflow portion fits in the mouth of the bottle of the stopper It has an effluent guide part recessed in the matching inner plug part and an outlet opening at the bottom of this effluent guide part, and the intake part is provided at a position away from the recessed part of the outflow part of the inner plug part. And at least its inlet Is made of an elastic seal member, is closed with compression to the closed position by contacting the lid from the closed position locked by the lock member, is restored by unlocking the lid, and the lid is pushed open to the closed position This is another feature.

  In such a configuration, in addition to the case of one feature, the outflow portion is further provided with an effluent guide portion that is recessed inside the inner plug portion that fits inside the mouth of the bottle, and an outflow port at the bottom thereof. In addition, the content liquid that has flowed out from the outflow port can be prevented from being disturbed by guidance in the range where the outflow liquid guide is recessed, and it is easy to prevent the outflow liquid from flowing to the intake portion side.

  The intake structure of the bottle of the present invention is attached so as to be detachable from the mouth of the vacuum double-structured bottle, and the bottle has an outflow part that flows out into the bottle and is used for pouring and direct drinking. An air intake part that allows air to be sucked in from the outside when the content liquid flows out is also provided, and the lid that is hinged to the stopper and opens and closes the outer periphery of the stopper is closed. In the intake structure of the bottle that is automatically locked in the closed position by the lock member in the closed state, and the lock is released by the unlocking operation, the stopper is attached so as to be detachable from the outside of the bottle mouth And an inner plug portion that is press-fitted to the inner periphery of the plug body portion via an annular seal packing, and the intake portion is separated from the recessed portion of the outlet portion of the inner plug portion. Provided in the position At least the inlet port portion is made of an elastic seal member integrally formed with the seal packing, and is closed with compression from the front of the closed position locked by the lock member to the closed position with compression to the closed position. Another feature is that it is provided so that it is restored by release and the lid is closed and pushed to the front.

  In such a configuration, in addition to the case of one feature, an inner stopper portion having an effluent guide and an outlet is further provided on the inner periphery of the stopper main body portion that is attached so as to be detachable from the outer periphery of the bottle mouth. It is press-fitted through an annular seal packing, and the mounting state is maintained by the seal pressure and seal friction acting between both sides, and liquid leakage between both sides can be prevented, and the seal pressure and seal friction can be prevented. It is possible to pull out the resistance inner stopper portion from the inner periphery of the stopper main body portion and make them independent from each other. In addition, the seal member of the intake port portion is integrally formed with the annular seal packing and can be equipped with a small number of parts.

  Further features of the present invention will become apparent from the following specific description and drawings. Each feature of the present invention can be used alone or in combination with various combinations.

  According to one feature of the bottle intake structure of the present invention, a lid that is locked in the closed position when the lid is closed while an intake portion is provided in addition to the outlet portion of the stopper to facilitate smooth outflow of the liquid contents. In order to prevent the content liquid from flowing out by closing the outflow portion and the intake portion through individual seal members that only need to be in a range corresponding to them, an annular or cylindrical intake port that protrudes toward the lid side of the intake portion Leakage is maintained in a closed state in a sealed state with a sufficient amount of compression in an annular or cylindrical shape with a high degree of freedom of deformation by contact with a lid locked in the closed position with the seal part as a seal member In addition to preventing heat leaks reliably, when the lid is unlocked, it can be surely pushed out of the closed position where the lid is locked by restoring from the compressed state, and the lock member can be released immediately from the release operation. The lid is re-locked That's on that to prevent, can be operated to open to fully open side simply by, for example, put a hand on the lid, which became a half-open state.

  According to another feature of the bottle air intake structure of the present invention, in addition to the case of one feature, the outflow portion further flows out from the outflow port at the bottom of the effluent guide recessed inside the inner plug portion. The spilled liquid is turbulently guided by the guide of the recessed part of the spilled liquid guide, and directly drinks, so it is easy to pour and easy to drink and prevents the spilled liquid from flowing to the intake side. Thus, it is easy to avoid the intake portion from being blocked by the outflow water and causing the intake failure.

  According to another feature of the bottle air intake structure of the present invention, in addition to the case of one feature, an inner plug portion having an effluent guide and an outlet is attached so as to be detachable around the outside of the bottle mouth. It is press-fitted through an annular seal packing so that it can be attached to and removed from the inner periphery of the plug body. Both parts can be separated for easy cleaning such as cleaning, and the sealing member of the air intake is formed integrally with the annular seal packing, so the number of parts and assembly man-hours can be reduced, reducing costs. There is an advantage that it does not take time to remove the seal member and wash it.

  Hereinafter, the bottle intake structure according to the embodiment of the present invention will be described in detail with the same reference numerals given to the members and portions common to some specific examples shown in FIGS. Use for understanding.

  As shown in FIGS. 1A and 1B and FIGS. 6A and 6B, the bottle of the present embodiment is a vacuum double-structured bottle having a vacuum heat insulating space 2 between an inner wall and an outer wall made of stainless steel. 1 and a stopper 4 that is detachably attached to the mouth portion 1a of the bottle 1 and has an outflow portion 3 that flows out into the bottle 1 and flows out into the bottle 1 for pouring and direct drinking. The stopper 4 is connected to the outlet 3 through the bottle 1 and sucks from the outside when the content liquid flows out. The stopper 6 is hinged to the stopper 4 and opens and closes the outer periphery of the stopper 4. In the bottle, the intake portion 5 is also opened / closed together with the outflow portion 3 via the seal member 7 and is automatically locked in the closed position by the lock member 8 in the closed state, and the lock is released by the unlocking operation. 1 intake structure.

  The bottle 1 shown in FIG. 6 (a) shows a design example exclusively for cold insulation, the bottle 1 shown in FIG. 6 (b) is a design example for both cold insulation and heat insulation, and the bottle 1 for exclusive use of cold insulation is cold preservation and heat insulation. The stopper portion is made slimmer than the dual-purpose bottle 1, and is easy to use by being gripped with one hand, so that it is suitable for easier use. In addition, slimming of the bottle 1 for exclusive use of cold insulation is achieved without a cup, and both the bottle 1 for cold preservation and heat insulation is used for the contents liquid as shown in FIGS. 1 (b) and 6 (b). The cup 9 is attached so as to be detachable so as to cover the outside of the lid 6 so that it can be received and drunk. However, even the bottle 1 for cold storage can be assumed to have a cup. In any case, these are not mandatory.

  The intake structure of the present embodiment is particularly common to the examples of FIGS. 1 to 3 and FIG. 6, and the intake portion 5 is sealed at least by an annular or cylindrical air opening toward the lid 6. 1 and FIG. 4, which is made of a member 11 and is locked by the lock member 8, and closes in a sealed state with compression until it comes into contact with the lid 6 and reaches the closed position. The lid 6 is restored by unlocking and the lid 6 is pushed out of the locked closed position. As a result, the stopper 4 attached to the mouth 1a of the bottle 1 having the vacuum double structure is adapted to suck out the outside air through the suction part 5 into the bottle 1 and smoothly discharge the content liquid through the outflow part 3. However, in the closed state of the lid 6, both the outflow portion 3 and the intake portion 5 are closed by the lid 6 locked in the closed position. The intake portion 5 is independent from the outflow portion 3, at least on the lid 6 side. An annular or cylindrical intake port projecting in the direction is formed of the seal member 11, and when the lid is closed, the lid 6 is in contact with the lid 6 from a position close to the closed position where the lid 6 is locked by the lock member 8 and reaches the closed position. Since it is closed by generating a sealing pressure with compression in the liquid, liquid leakage and heat leakage can be prevented, and it is restored by unlocking the lid 6 and the lid 6 is pushed out of the closed position locked by the locking means 8. Because it opens Click portion 8 can be prevented from locking the lid 6 once again be released from the release operation to unlock after immediately.

  As a result, the suction part 5 is provided in addition to the outlet part 3 of the stopper 4 so as to smoothly discharge the content liquid with the intake air, while the lid 6 is in the closed state, the lid 6 locked to the closed position corresponds to the outlet part 3. In order to prevent the contents liquid from flowing out through the seal member 11 in the range corresponding to the seal member 12 in the range and the seal member 11 in the range corresponding to the intake portion 5, an annular or cylindrical intake air projecting toward the lid 6 side of the intake portion 5 With the mouth portion as the seal member 11, the ring 6 or the tubular shape having a high degree of freedom of deformation is maintained in a closed state in a sealed state with a sufficient degree of freedom of deformation by contact with the lid 6 locked in the closed position. Liquid leakage and heat leakage can be reliably prevented, and when the lid 6 is unlocked, the lid 6 is reliably pushed out of the closed position by restoration from the compressed state, and the lock portion 8 is immediately released. Even when released from operation, the lid 6 is Tsu on that prevents click to be of a can be operated to open the fully open side easily by, for example, applying a hand on the lid 6 became half open state. Therefore, it is easy to use even if the spring for urging the lid 6 to the fully open position is not applied. Of course, a spring that urges the lid 6 to the fully open position may be provided. In that case, a loose spring that suppresses sudden opening of the lid 6 may be employed, and the opening speed when unlocking may be slow. By the push-opening action of the lid 6 by the seal member 11, it is possible to avoid the inconvenience that the opening of the lid 6 is delayed and re-locked with respect to the release from the unlocking operation of the lock member.

Further, in the case of FIGS. 1 (a) and 1 (b) and the example of FIG. 6 (b), the outflow portion 3 is an effluent guide portion that is recessed in the inner plug portion 4a that fits into the mouth of the bottle of the plug 4. 3a and an outlet 3c opened to the bottom 3b of the effluent guide part 3a, and the intake part 5 is separated from the extract guide part 3a which is a recessed part of the effluent part 3 of the inner plug part 4a. It is assumed that it was provided at the position. Thereby, the outflow port portion 3 has the effluent guide portion 3a that is recessed inside the inner plug portion 4a that fits in the inner periphery of the mouth 1a of the bottle 1 and the outflow port 3c of the bottom portion 3b. The turbulence of the content liquid flowing out from the outlet 3c can be adjusted by guiding the recessed area of the effluent guide 3a, and at least a step S is secured between the effluent guide part 3a and the upper end opening of the intake part 5. This makes it easier to prevent the effluent from flowing to the intake section 5 side. Therefore, the outflow portion 3 guides the range in which the content liquid that has flowed out from the outflow port 3c in the bottom 3b of the effluent guide portion 3a that is recessed inside the inner plug portion 4a is recessed in the effluent guide portion 3a. Since it is easy to pour and drink directly, the spilled liquid is prevented from flowing to the intake part 5 side and the intake part 5 is blocked by the spilled water. It is easy to avoid becoming. On the other hand, in the example of FIG. 6 (a), the outflow part 3 has a cylindrical shape that rises upward from an outlet 3c that is open to an inner stopper part 4a that is applied to the upper end of the mouth 1a of the bottle 1 via a seal member 21. By having the effluent guide portion 3a, the isolation from the intake portion 5 provided at a position away from the rising effluent guide portion 3c is further enhanced.

  Further, the stopper 4 is common to the examples of FIGS. 1A, 1B, 6A, and 6B, and is attached to the outside of the mouth 1a of the bottle 1 so as to be detachable. And an inner plug portion 4a that is press-fitted to the inner periphery of the plug main body portion 4b via an annular seal packing 21, and at least the intake port portion of the intake portion 5 is integrated with the seal packing 21. The seal member 11 is formed of an elastic seal member 11 and is closed with compression from the front of the closed position locked by the lock member 8 to the closed position with the compression to the closed position. Is provided so as to be pushed open to the close position. As a result, an annular seal packing 21 is provided on the inner periphery of the stopper main body 4b that is attached so that the inner stopper 4a having the effluent guide 3a and the outlet 3c can be attached to and detached from the outer periphery of the mouth 1a of the bottle 1. In addition to being able to prevent the liquid leakage between the two, the inner plug is resistant to seal pressure and seal friction. The parts 4a can be extracted from the inner periphery of the plug body part 4b to make them independent from each other. Moreover, the seal member 11 of the air inlet portion 5 is integrally formed with the annular seal packing 21 and can be equipped with a small number of parts.

  Accordingly, an annular seal packing is provided so that the inner plug portion 4a having the effluent guide portion 3a and the outlet port 3c can be attached to and detached from the inner periphery of the stopper main body portion 4b to be attached to the outer periphery of the mouth 1a of the bottle 1. It is press-fitted through 21 and can be handled as a single piece while maintaining the mounting state by seal pressure and seal friction, while separating both of them against seal pressure and seal friction, making it easy to clean and wash. In addition, since the seal member 11 of the inlet portion 5 is integrally formed with the annular seal packing 21, the number of parts and assembly man-hours can be reduced, and the cost can be suppressed. There is an advantage not to hang.

  Here, FIG. 1A will be described in more detail with reference to FIGS. The stopper body 4b includes an outer peripheral wall 41 that is screwed to a screw 23 formed on the outer periphery of the mouth 1a of the bottle 1 and an inner peripheral wall 42 that fits on the inner periphery of the mouth 1a. The peripheral wall 42 is formed as an individual resin molded product so that the degree of freedom of molding is increased to facilitate molding, and the flange portions facing each other are partially overlapped and integrated by high frequency welding or the like to be integrated into the mouth 1a. I try to cover it. A bearing portion 25 for hinge-connecting the lid 6 with a shaft 24 is integrally formed on the rear wall portion on the side of the outer peripheral wall 41 so that the rear portion of the lid 6 can be opened and closed. A locking portion 43 for locking the lid 6 in the closed position is integrally formed on the front portion of the inner peripheral wall 42 opposite to the bearing portion 25, and is pivotally supported by the shaft 26 on the front portion of the lid 6. The lock member 28 urged so as to hold the lock position by the spring 27 is automatically engaged with the hook 8a at the tip portion facing downward to the locking portion 43 when the lid 6 is closed. 6 can be locked in the closed position.

  On the other hand, the inner plug portion 4a has an upper flange portion 31 that is press-fitted from below through an annular seal packing 21 up to the inner peripheral upper end of the inner peripheral wall 42 of the plug main body portion 4b, and a lower end portion of the inner peripheral wall 42 through a seal packing 29. A lower lunge portion 32 that abuts from below, and the outflow portion 3 and the intake portion 5 have the form described above so as to penetrate between the lower flange portion 32 and the upper flange portion 31. It is integrally molded. The outflow part 3 is provided at a position near the front half of the inner plug part 4a to form a recessed effluent guide part 3a and an outlet 3c at the bottom part 3b. The upper flange part 31 and the lower part are formed at the rear part of the outflow part 3. An air intake portion is formed by a resin passage 5a that connects the flange portion 32 up and down, and a seal member 11 that is connected to the upper end of the resin passage 5a and forms an air port 5b that protrudes in a cylindrical shape on the upper flange portion 31 and thus on the lid 6 side. 5 is formed.

  The stopper main body 4b and the inner stopper 4a can be handled as an integrated body as described above in terms of the fitting structure in a sealed state via the sealing member 21, and the stopper main body 4b is connected to the mouth 1a of the bottle 1. When screwed, the seal packing 33 attached to the outer periphery of the lower end of the lower flange portion 32 of the inner plug portion 4a is pressed against a step portion 34 formed by drawing the inner peripheral portion of the base of the mouth 1a of the bottle 1 inward, The gap between the stopper 4 and the mouth 1a is sealed so that the content liquid does not flow. Further, when the entire stopper 4 is handled alone, the sealing members 21 and 29 prevent the liquid from entering between the inner peripheral wall 42 of the stopper main body 4b and the inner stopper 4a.

  Corresponding to the fact that the bottle 1 is a slim type that can be held and used with one hand, an unlocking member 35 that can be unlocked with the thumb of one hand that holds the bottle 1 is provided. . The unlocking member 35 has an inverted L-shaped cross section as shown in FIGS. 1 to 3, and can swing on the resin spring portion 36 provided at the front portion of the lid 6 in conjunction with the vertical slide and the locking member 8. 2 and held in the down-operated non-operation position shown in FIG. 2 (a), is flush with the outer surface of the lid 6 and holds the upward-released operation position bottle 1 shown in FIG. 2 (b). When it is slid with a thumb or the like, a release operation of projecting upward from the flush state with the lid 6 and pushing backward is possible. Therefore, when the unlocking member 35 is pushed backward in the state of FIG. 2B, the fine end unlocking member 35 of the locking member 8 pushes the portion end 8b of the locking member 8 and moves to FIG. ), The engagement with the locking portion 43 is released, so that the lock of the lid 6 to the closed position can be released by one member operation that can be performed with one continuous touch of the unlocking member 35. When the lock is released, the lid 6 is pushed open to the outside of the lock position by the elastic restoring force of the seal member 11. Therefore, the user can put the hand on the lid 6 that is half-opened and perform the opening operation toward the fully open side as shown in FIG.

  When the unlocking member 35 is released from the unlocking operation after the lid 6 is unlocked, the locking member 8 becomes free and returns to the state shown in FIG. When the lid 6 is closed in this state, the lock member 8 works to lock the lid 6 in the closed position again, and then the lock release member 35 is manually operated to move down to the non-operating position in FIG. Then you can return to the initial state. But the lock release member 35 can also be automatically returned to a non-operation position by the urging | biasing of a spring.

  The lid 6 includes a resin outer plate 61 equipped with a lock member 8 and an unlock member 35, and a hollow shaft 61a projecting from the lower surface of the outer plate 61 as shown in detail in FIGS. The hollow portion 62a corresponding to 3 is fitted into the outer plate 61 and the resin inner plate 62 integrated by ultrasonic welding or the like to form a hollow, and the inner plate 62 enters the effluent guide portion 3a to enter the lower end. A hollow projection 62b that presses against the outlet 3c with the sole member 12 attached thereto to close it in a sealed state, and a projection 62c that presses against the seal member 11 forming the intake port 5b and closes it into a sealed state. Is forming.

  In the example shown in FIG. 1 (b), a screw 63 having a diameter larger than that of the screw 3 and smaller than the diameter of the barrel portion of the bottle 1 is formed below the formation portion of the screw 23 for screwing the stopper 4 around the outside of the mouth 1 of the bottle 1. A cup 9 with a metal cover 9a is provided so that it can be screwed on and off, and the lid 6 can be slid back and forth on its top plate as shown in FIG. 1 (b), FIG. 4 and FIG. A lock member 8 is provided and urged rearward so as to be kept in a locked position by a spring 27. When the lid 6 is closed, a hook 8a at the front end formed to project to the left and right of the lock member 8 is connected to the plug 4. The lid 6 is automatically locked in the closed position by engaging with a pair of engaging portions 43 formed forward on the left and right sides of the top surface of the outer peripheral wall 41. It is. Therefore, the lock member 8 is pushed forward with its rearward stepped portion 8c with the thumb of the hand holding the bottle 1 with the cup 9 removed, thereby engaging the locking portion 43 of the hook 8a. By removing, there is an advantage that the lock of the lid 6 to the closed position can be released by a one-touch operation and the lock release member can be omitted. The other structure is not particularly different from the example shown in FIG.

  In the example shown in FIG. 6A, the lock member 8 pivots upward on the stopper 4 side, and the upward hook portion 8a is elastically engaged with a locking portion 43 provided on the free end side of the lid 6. The lid 2 is locked in the closed position, and the lock release operation member 35 provided on the side of the stopper 4 is moved downward so as to be positioned outside the lock member 8, and then the lower end is pushed to operate the lock member. The tail end 8b of 8 is pushed against the spring 27 so that the lock can be released. The sealing member 12 on the side of the lid 6 that closes the outflow portion 3 is fixed to the base portion 12a by fitting the base portion 12a to the cylindrical portion 6a integrally formed on the bottom surface of the top plate 6 so that it can be attached or detached. It has a flange portion 12b protruding from 12a and presses against the upper end of the cylindrical effluent guide 3a so as to close it in a sealed state. Further, the seal member 21 provided between the fitting portions of the plug main body 3b and the inner plug 3a follows the structure integrally formed with the seal member 11 of the intake section 3 as described above, The gap between the bottle 1 and the upper end of the mouth 1a is also sealed. Compared to other examples, the plug structure and the seal structure are simplified. Other structures are not particularly different from other examples.

  In the example shown in FIGS. 6B, 7, and 8, the screw 71 provided with the inner peripheral wall 42 of the stopper main body portion 3 b on the inner periphery of the mouth 1 a of the bottle 1 to screw and attach the cup 9. The shoulder member 82 made of resin cannot be forced around the base of the mouth 1a exposed by making the outer peripheral wall 41 of the plug body 3b shorter than the mouth 1a. The cup 9 is screwed onto a screw 84 formed on the outer periphery of the shoulder member 82. The shoulder member 82 is provided with a connecting pin 85 for connecting a hanging strap (not shown). The other structure is not particularly different from the example shown in FIG.

  The seal member 11 and the seal packing 21 are integrated, and can be attached and detached from a fitting portion such as a groove in which the seal packings 29 and 33 are individually attached.

  The present invention is practically used for an air intake structure attached to an outflow part for pouring or directly drinking the content liquid in a portable vacuum double structure bottle, and with a simple seal structure, liquid leakage, heat leakage, suction It functions without defects and can be pushed out of the locked position when the lid is unlocked to the closed position by the sealing member of the intake section.
