  However, in the lid braking structure disclosed in Patent Documents 1, 2, and 3, the protruding piece or tongue piece of the lid contacts or slides on the outer periphery of the bearing portion that hinge-connects the lid of the stopper. Even if resin springiness is given to the piece, it is easy to wear due to contact and sliding contact between resins that have a limit in springiness in terms of manufacturing, and problems such as early breakage if durability is ignored Occurs. Further, in the plug structure described in Patent Document 4, the rear edge of the lid is suddenly brought into contact with the protrusion on the outer periphery of the bearing portion of the plug while the lid is opened with a spring. They are large and tend to wear each other, and the braking function that allows the lid to be opened slowly cannot be expected.

  It is an object of the present invention to provide a bottle lid braking structure that can be opened gently by braking at least at the end with less mutual wear even when the lid is unlocked and opened. is there.

  In order to solve the above-described problems, the bottle lid braking structure of the present invention is attached so as to be detachable from the mouth of a vacuum double-structured bottle, and the contents liquid is allowed to flow out into the bottle and used for pouring and direct drinking. And a stopper that is hinged to the stopper to open and close the outer periphery of the stopper together with the outflow portion, and in a closed state, is automatically moved to the closed position by a spring member that is biased to maintain the locked position by a spring. In the bottle lid braking structure, which is configured to brake at least at the end of the opening operation of the lid, the lock member is biased by a spring to the hinge connection side and held in the locked position. When the lid is closed, the engaging part facing the hinge connection side automatically elastically engages with the locking part provided on the plug side facing the anti-hinge connection side to lock the lid in the closed position. Before at least the end of the lid opening movement It is one of the features that it has a spring to serve as a braking force to provide a resistance to the operation to the final open position of the lid.

  In such a configuration, when the lid is closed, the lock member supported by the lid is urged by the spring to the hinge coupling side, and the engagement portion facing the anti-hinge coupling side on the plug side faces the hinge coupling side. Since the joint portion automatically elastically engages and locks the lid in the closed position, the lid covers the outer periphery of the stopper, and the outlet portion of the stopper can be held closed. When the lid is unlocked and opened by the unlocking operation to the anti-hinge connection side against the spring of the lock member, the spring that the lock member biases it at least at the end is opened. It can be made to open slowly by acting as a braking force that gives resistance to the movement to the final opening position.

  The bottle lid braking structure of the present invention is also mounted so that it can be attached to and detached from the mouth of the vacuum double-structured bottle, and the stopper has an outflow part that allows the content liquid to flow out into the bottle and serve for pouring and direct drinking. The stopper is hinged to open and close the outer periphery of the stopper together with the outflow portion, and in the closed state, it is automatically locked in the closed position by a lock member biased so as to maintain the locked position by a spring. In a bottle lid braking structure comprising a lid and braking at least at the end of the opening operation of the lid, the lock member is biased by a spring on the hinge coupling side and held in the locked position, and is hinged when the lid is closed The engagement portion facing toward the side automatically and elastically engages with a locking portion provided on the plug side toward the anti-hinge connection side to lock the lid in the closed position, and the engagement portion resists the spring. Remove the lock from the locking part to the anti-hinge connection side and lock The unlocking operation section to be removed is provided so as to face the top surface of the lid, and at least at the final stage of the lid opening operation after unlocking, the spring acts as a braking force that provides resistance to the operation of the lid to the final opening position. This is another feature.

  In such a configuration, in addition to the case of one feature, the lock member that locks the lid closed by being biased by the spring on the hinge connecting side in the closed position, the operation unit facing the top surface of the lid is anti-hingeed. The lock can be released simply by operating the connecting side against the spring.

The bottle lid braking 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 the stopper has an outflow part that flows out into the bottle and is used for pouring and drinking directly, A lid which is hinged to the stopper, opens and closes the outer periphery of the stopper together with the outflow portion, and is automatically locked in the closed position by a lock member biased so as to maintain the locked position by a spring in the closed state; In the bottle lid braking structure, which is braked at least at the end of the opening operation of the lid, the lock member is urged by a spring on the hinge connection side and is held in the locked position, and on the hinge connection side when the lid is closed. The facing engaging portion automatically elastically engages with the engaging portion provided on the stopper side and on the anti-hinge connection side to lock the lid in the closed position, and at least the final stage of the lid opening operation after unlocking in the lid by the biasing force of the spring It is in sliding contact with the bearing portion for receiving an axis hinged, and that it has to Kassel work as a braking force to provide a resistance to the spring operation to the final open position of the lid and other features.

  In such a configuration, in addition to the case of one feature, the lock member is further slidably contacted with the outer periphery of the bearing portion that hinge-connects the spring that biases the lock member to the hinge connection side. Therefore, both of them can be made to act as a braking force without having springiness.

  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 characteristic of the bottle lid braking structure of the present invention, the engagement portion facing the hinge connection side of the lock member urged by the spring on the hinge connection side is formed on the anti-hinge connection side only by closing the lid. It automatically and elastically engages with the locking part of the plug that faces, and the cover is locked in the closed position, and the cover keeps the outer periphery of the plug and the outlet part of the plug in a closed state, thereby preventing liquid leakage and heat leakage. . The lock on the lid of the closed position, it is possible to release by the operation of the counter-hinged side against the spring of the locking member, the anti-hinged side like hand thumb gripping the bottle from the hinged side The release operation can be easily performed by a natural operation that pushes the button. Even though the lid is opened after unlocking, it is opened slowly with a spring that is biased by the locking member at least at its end as a braking force that provides resistance to movement of the lid to the final opening position. It is possible to avoid the premature damage due to the spring property being imparted to the member to reduce the lifespan, or the rough opening operation or the excessive opening operation by the spring bias.

According to another feature of the bottle lid braking structure of the present invention, in addition to the case of one feature, the lock member further operates the operation portion facing the top surface of the lid against the spring on the anti-hinge connection side. Since the lock can be released only by this, it is suitable for releasing the lock by pushing the bottle with the thumb of one hand holding the bottle from the hinge connecting portion side.

According to another feature of the bottle lid braking structure of the present invention, in addition to the case of one feature, the lock member further includes a spring biasing it toward the hinge coupling side, and the lid is hinged to the stopper. Therefore, the locking member and the bearing portion that are in sliding contact with each other need not be provided with spring properties, and both the lock member and the bearing portion are provided with spring properties. As compared with the case, it is possible to prevent damage at an early stage , and the life is improved.

  Hereinafter, a bottle lid braking structure according to an embodiment of the present invention will be described in detail with reference to one specific example shown in FIGS. 1 to 4 to provide an understanding of the present invention.

As shown in FIG. 1, the bottle of the present embodiment is attached to a bottle 1 mouth portion 1a having a vacuum double structure having a vacuum heat insulating space 2 between an inner wall and an outer wall made of stainless steel. A plug 4 having an outflow part 3 for allowing the content liquid to flow out into the inside and serving for pouring and direct drinking, and a hinge connected to the plug 4 by a shaft 24 to open and close the outer periphery of the plug together with the outflow part 3 and in a closed state The lid 6 is automatically locked in the closed position by the lock member 8 biased so as to maintain the locked position by the spring 27, and brakes at least at the end of the opening operation of the lid 6. In the illustrated example, the stopper 4 is provided with an intake portion 5 that leads into the bottle 1 and sucks in from the outside when the content liquid flows out, and is connected to the outlet 4 by a hinge to open and close the outer periphery of the stopper 4. When the lid 6 to be closed is closed, the intake portion 5 is also opened and closed via the seal member 7 together with the outflow portion 3, and in the closed state, the lock member 8 is automatically locked to the closed position, and the lock is released by the unlocking operation. The bottle 1 has an intake structure. However, such intake cultivation is not essential. As shown in FIGS. 1 and 2, the cup 9 is attached so as to be detachable so as to cover the outside of the lid 6 so that the content liquid can be received and drunk. However, this is not essential.

  In the lid braking structure of the present embodiment, as shown in FIGS. 1 and 2, the lock member 8 is biased by a spring 27 on the hinge connecting side and held in the locked position, and is hinged when the lid 6 is closed. As shown in FIGS. 1, 3, and 4, hook-like engaging portions 8 a as shown in FIGS. 1, 3, and 4 facing the connection side are provided on the stopper 4 side and facing the anti-hinge connection side. 1 automatically locks into a claw-shaped locking portion 43 to lock the lid 6 in the closed position as shown in FIG. 1, and the spring 27 is closed at least at the end of the opening operation of the lid 6 after unlocking. It is made to work as a braking force that gives resistance to the movement to the final opening position. Thus, when the lid 6 is closed, the lock member 8 supported by the lid 6 is urged by the spring 27 to the hinge coupling side and the locking portion 43 facing the anti-hinge coupling side on the plug 4 side is connected to the hinge coupling side. Since the engaging portion 8a facing the door automatically elastically engages and locks the lid 6 in the closed position, the lid 6 covers the outer periphery of the stopper 4, and the outlet portion 3 and the intake portion 5 of the stopper 4 are connected to the sealing member 7. The individual sealing members 12 and 11 can be held in a closed state. The lid 6 is unlocked and opened by the unlocking operation to the anti-hinge connection side against the spring 27 of the lock member 8, but the spring that the lock member 8 biases it at least at the end thereof 27 can be made to open slowly by acting as a braking force that gives resistance to the movement of the lid 6 to the final opening position.

  As a result, just by closing the lid 6, the engagement portion 43 facing the hinge connection side of the lock member 8 biased by the spring 27 on the hinge connection side becomes the locking portion 43 of the plug 4 facing the anti-hinge connection side. The lid 6 is automatically elastically engaged and locked in the closed position, and the lid 6 holds the outer periphery of the plug 4 and the outflow portion 3 and the intake portion 5 of the plug 4 in the closed state by the seal members 12 and 11. Liquid leakage and heat leakage can be prevented. Since the lock of the lid 6 to the closed position can be released by an operation to the anti-hinge connection side against the spring 27 of the lock member 8, the bottle 1 is moved to the anti-hinge connection side with the thumb of one hand holding the bottle 1 from the hinge connection side. The release operation can be easily performed by the natural operation of pushing. Although the lid 6 is opened after unlocking, the spring 27, which is biased by the locking member 8 at least at the end thereof, is slowly opened by acting as a braking force that provides resistance to the operation of the lid 6 toward the final opening position. Therefore, a spring (not shown) is applied between the stopper 4 and the lid 6 by imparting a spring property to the resin member to shorten the life, or by operating between the stopper 4 and the lid 6 by rough opening operation or attaching a vine part around the shaft 24. It is possible to avoid early damage due to excessive opening operation due to the urging of.

  Further, the lock member 8 includes a lock release operation portion 8b for releasing the lock by releasing the engagement portion 8a from the engagement portion 43 to the anti-hinge connection side against the spring 27 as shown in FIGS. Thus, it is provided so as to face the top surface 6a of the lid 6 through the window 6c. Thus, the lock member 8 that locks the closed lid 6 biased by the spring 27 toward the hinge connection side in the closed position opposes the operation portion 8b facing the top surface 6a of the lid 6 against the spring on the anti-hinge connection side. The lock can be released simply by operating. Accordingly, the lock member 8 can be unlocked simply by operating the operation portion 8b facing the top surface 6a of the lid 6 against the spring 27 against the anti-hinge connection side, so that the bottle 1 can be released from the hinge connection portion side. It is suitable for releasing the lock by pushing with the thumb of one hand holding.

Further, the lock member 8 hinge-connects the lid 6 of the plug 4 with the spring 27 as a braking force that provides resistance to the movement of the lid 6 to the final opening position at least at the end of the opening operation of the lid 6 after unlocking. It is made to work by sliding between the bearing portion 25 that receives the shaft 24. As a result, the lock member 8 is springy for both of the spring 27 urging the lock member 8 toward the hinge connection side due to the sliding contact relationship with the outer periphery of the bearing portion 25 that hinge-connects the lid 6 to the plug 4. It can work as a braking force without having. Accordingly, the lock member 8 causes the spring 27 urging it to the hinge connection side to act as a braking force by the sliding contact relationship with the outer periphery of the bearing 25 that hinge-connects the lid 6 to the plug 4. Neither the locking member 8 and the bearing portion 25 that are in contact with each other need to be provided with springiness, and damage is caused early by comparing with the case where both the locking member 8 and the bearing portion 25 are provided with springiness. Can be prevented and the service life is improved.

Specifically, the lock member 8 is made of a resin product so as to have a substantially Z-shaped cross section having two steps of large and small steps toward the hinge connection side as shown in FIGS. 1, 2, and 4C. A tail piece 8d that is formed and extends from the small step portion 8c to the hinge connection side is formed between the upper plate 61 and the lower plate 62 that make the lid 6 hollow. The operation part 8b formed by a large step part and the guide piece 8e extending from the operation part 8b to the anti-hinge connection side are also covered with the cover. faces fitted into the recess 64 of the top surface 6a navel through a window 6c formed in the top surface 6a of 6, is guided and tail piece 8d and guide piece 8e in the recess 64 of the top surface of the holding hole 63 and the lid 6 The right and left engaging portions 8a project from the left and right sides of the plug 4. And locking position of the hinge connection portion to be engaged with the engagement portion 43 provided in, and is to be stably slid between the unlocked position of the anti-hinged side. The tip of the tail piece 8d of the locking member is narrowed in a tongue-like shape so that the outer periphery of the bearing portion 25 and the friction width do not increase unnecessarily. Further, a cam surface 25a having a diameter around the shaft 24 is formed on the lid opening side on the outer periphery of the bearing portion 25 so that the braking force increases as the degree of opening of the lid 6 increases. A click function that allows the tongue 8d1 to engage with a step 25b between the end of the cam surface 25a and the outer periphery of the bearing portion 25 at the open position to give a light resistance to the operation of closing the lid 6 and stabilize the lid 6 in the open state. As a part. The cam surface 25b can also be a partial circumferential ridge that applies braking only in the required opening range of the lid 6.

More specifically the further, the inlet section 5, on at least an annular or tubular air inlet portion of the lid 6 side becomes the sealing member 11, closing shown in FIG. 1, the lid 6 is locked by the locking member 8 located It is closed in a sealed state with compression until it comes into contact with the lid 6 before reaching the closed position, and is restored by unlocking the lid 6 to push the lid 6 out of the locked closed position. I have to. 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, the outflow portion 3 includes an effluent guide portion 3a that is recessed in the middle plug portion 4a that fits into the mouth of the bottle of the plug 4, and an outflow port 3c that is open to the bottom portion 3b of the effluent guide portion 3a. The intake portion 5 is provided at a position away from the effluent guide portion 3a which is a recessed portion of the outflow portion 3 of the inner plug portion 4a. 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.

  Corresponding to this, the lid 6 enters the effluent guide portion 3a into the lower plate 62, presses against the outlet 3c by the seal member 12 and closes in a sealed state, and the seal member 11 of the intake portion 5. And a press-contact portion 62b that closes in a sealed state. Further, by utilizing this, the spring 27 is operated between the inside of the operation portion 8b and the effluent guide portion 3a facing each other in the sliding direction of the lock member 8.

  Furthermore, the stopper 4 is press-fitted so that it can be attached / detached via an annular seal packing 21 to the inner periphery of the stopper body 4b, which is attached to the outside of the mouth 1a of the bottle 1 so as to be attached / detached. The intake portion 5 is formed of an elastic seal member 11 having at least an intake port portion formed integrally with the seal packing 21 and is locked by the lock member 8 before the closed position. The lid 6 is closed with compression to the closed position, and is restored by unlocking the lid 6 so that the lid 6 is pushed open to the front of the closed position, and the lid 6 is biased toward the fully opened position. Even if the initial movement of opening the lid 6 may be delayed from the release of the unlocking operation force, the lid 6 will be re-locked by suppressing the biasing force as much as possible in order to make the spring to act. Inconvenience It is possible to avoid. Further, an annular seal packing 21 is provided on the inner periphery of the stopper main body 4b to which the inner stopper part 4a having the effluent guide part 3a and the outlet 3c is detachably attached to the outer periphery of the mouth 1a of the bottle 1. It is press-fitted through, and the mounting state is maintained by the seal pressure and seal friction acting between both sides, and it is possible to prevent liquid leakage between both sides, and also against the seal pressure and seal friction, the inner plug part 4a can be extracted from the inner periphery of the plug body 4b to make them independent of 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.

  Further, in order to install the cup 9 by screwing, the inner peripheral wall 42 of the stopper main body 3b is attached by being screwed to the screw 71 provided on the inner periphery of the mouth 1a of the bottle 1, and the stopper main body 3b A resin shoulder member 82 is forcibly fitted around the base of the mouth 1a exposed by making the outer peripheral wall 41 shorter than the mouth 1a, and is formed on the outer periphery of the shoulder member 82. The cup 9 is screwed onto the screw 84. The shoulder member 82 is provided with a connecting pin 85 for connecting a hanging strap (not shown). The cylindrical inner plug portion 4a includes a flange portion 32 that presses and seals between the lower end of the inner peripheral wall 42 of the plug main body portion 4b via a seal packing 29, and a lower end portion that extends to the flange portion 32 The seal packing 33 attached to the bottle 1 is pressed against an inward projection 1b in which the bottle 1 is drawn at the lower part of the mouth 1a of the bottle 1 so as to seal between the bottle 1. 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.
