  The screw cap and the hinge-shaft combined type as in Patent Document 1 do not have a drinking stopper structure for pouring a drink, so the front direction is difficult to recognize, and when viewed from above, the lid engagement It is difficult to recognize whether the lid is locked or released, that is, whether the lid is moving up or down.

  In the lid separation type in the screw cap type lid as in Patent Document 2, it is necessary to hold the removed lid by hand or place it on a desk, so that the detachability operability is not simple. On the other hand, in the case where the lid is connected to the stopper through a relatively long connecting member as in Patent Document 2, the lid that is hung when the container is tilted and drinks is an obstacle, and in some cases, the lid may fall on the forehead or the like. In addition, since the position and orientation move relatively freely in the removed state, it is necessary to operate the screw positions one by one when attaching, which is not convenient. Furthermore, in the one that rotates halfway as in Patent Document 4 and generates the flow gap, the drinking water flow path does not fully open, so it is difficult to recognize the flowability of the drink, that is, the change in flow rate, speed, and liquid level, Because it is difficult to control, there is a concern that the desired amount may not come out, or the amount may exceed the expected amount, which is not convenient and may cause burns.

  In addition, the one-touch open type as disclosed in Patent Document 5 requires a button / lock member for latching the lid and a spring member for biasing the lid / button, resulting in a complicated structure, assembling performance and product cost. If the protrusions of the button / lock member are located on the top or front of the stopper, it will be a hindrance when drinking, carrying, or storing, and the protrusion will be dropped. If it is damaged or caught in the bag, and the lid is ejected and rotated by a spring member, drinking water droplets adhering to the water-stopping packing of the lid will scatter when the lid is opened vigorously. The surroundings may get dirty or you may be surprised by the momentum of the lid opening.

  Moreover, since the manual flap type like Patent Document 6 is a non-water stop or simple water stop structure mainly used on a table, there is no or insufficient structure for locking the lid in the closed state. The lid may open at the time of dropping or dropping and the beverage may leak.

  Furthermore, in the manual injection hole lever rotating type as in Patent Document 7, since the container opening and the liquid flow path are not fully opened when drinking, it is difficult to recognize the outflow property of the beverage and it is difficult to control. There is a concern that the amount may not come out, or the amount more than expected may come out, which is not convenient and may cause burns. Further, since the liquid flow path is not fully opened, the cleaning property is poor and not hygienic.

  Furthermore, the arc length A of the liquid injection hole 33 is longer than the arc length B of the second female screw 29, and the arc length of the connecting bridge 34 from the arc length C of the gap 31 between the second female screws 29. The length D is formed small, and the connecting bridge portion 34 is arranged in the middle of the gap 31 in plan view. Further, the width E in the direction of the central axis 10 of the liquid injection hole 33 is formed larger than the thread of the second female screw 29, that is, the width F in the direction of the central axis 10 side.

  In addition, a recess 35 is formed on a part of the front side of the outer peripheral wall of the drinking mouth 18, and this recess 35 forms a liquid dripping receiving portion that also serves as a mouth attaching portion. A drinking mouth cover 36 that is disposed so as to face the connecting bridge portion 34 and that can cover the outside of the concave portion 35 is bent downward and connected to the front portion of the ring member 20.

Furthermore, the hinges accept part 16, the hinge portion 23, the hinge shaft 24 will be described. Around the rotational center axis 37 is a hinge shaft 24 be one that is horizontally disposed so as to face the central axis 10, hinges accept part 16 is a lateral cylindrical, peripheral wall 17 By forming a recess in the rear part, a pair is arranged on the left and right sides of the recess. The inner wall penetrating part 38 hinge shaft 24 is inserted are formed along a central axis of rotation 37, also facing each other in the right and left pair of hinges accept part 16 substantially in the center of the hinges accepted part 16 16A is formed in a state orthogonal to the rotation center axis 37. The diameter of the through portion 38 is formed to be the same as or slightly smaller than the diameter of the hinge portion shaft 24.

  The hinge portion 23 is formed by a convex portion that protrudes rearward and vertically in the center of the rear portion that is cut out to draw a string on the ring member 20, and is disposed between the pair of left and right inner walls 16A. 23 is formed in a laterally elliptical column shape as a whole, and its outwardly facing surface 23A facing in the left-right direction is orthogonal to the rotation center axis 37 and faces the inner wall 16A. Then, the width between the pair of left and right outward faces 23A before assembly and the protrusion of the click protrusion 42 to be described later provided in the direction of the rotation center axis 37 are provided on the pair of left and right outward faces 23A before the assembly from the width between the pair of left and right inner walls 16A. The total length is set slightly longer. For this reason, when assembling as shown in FIG. 3, the click protrusion 42 is in pressure contact with the inner wall 16A, and when the lid body 4 is opened and closed by rotating, the pair of left and right inner walls 16A faces a pair of left and right outwards. The click protrusion 42 provided on the surface 23A slides. Further, the horizontal elliptical columnar hinge part 23 is arranged with the minor axis direction in the outer direction of the ring member 20 and its peripheral surface, and the major axis direction parallel to the direction of the opening / closing operation disc part 25 and the short cylinder part 26. The hinge shaft hole 39, which is disposed and penetrates between the pair of left and right outward faces 23A through which the hinge shaft 24 is inserted, has an inverted L-shape whose longitudinal section is not circular but long in the major axis direction. It has a long hole shape. That is, the width of the hinge shaft hole 39 in the minor axis direction is the same as or slightly larger than the diameter of the hinge portion shaft 24. On the other hand, the length of the hinge shaft hole 39 in the major axis direction is about 1.5 to 2.5 times the diameter of the hinge shaft 24. Further, a recess 40 is formed at the upper end of the hinge shaft hole 39 toward the opening / closing operation disc portion 25 side, and this recess 40 protrudes in an arc shape toward the opening / closing operation disc portion 25 side. The depth of the hinge portion shaft 24 is less than half the diameter of the hinge portion shaft 24 so that the hinge portion shaft 24 can be locked. The length of the hinge shaft hole 39 in the major axis direction is changed from the closed state where the lid 4 is dropped into the lower cylindrical portion 14 to the open lid fixed state, or vice versa, as will be described later. The hinge part shaft 24 is formed in such a length that it can move correspondingly.

Furthermore, in order to kept tilted the lid 4 in the fully opened, providing a click mechanism between the hinges accept part 16 and the hinge portion 23. This click mechanism has a relief recess 41 formed on the inner wall 16A and a click projection 42 provided on the outward surface 23A. The click projection 42 is arranged on the upper portion of the outward surface 23A. Projecting in the 37 direction, the tip is in contact with the inner wall 16A. On the other hand, for the first time, the drinking mouth cover 36 is further inclined downward through the upward state from the closed state in the rotation locus of the click projection 42 when the lid body 4 is rotated about the hinge shaft 24 as the rotation center. An inner wall 16A is formed in which the tip of the click projection 42 does not come into contact with the fixed region. In the embodiment, the relief recess 41 is formed from the upper part of the inner wall 16A to the outer side, that is, the part opposite to the upper cylindrical part 12 and further to the lower part.

  Further, the elastic plate portion 43 is provided integrally with the hinge portion 23. The elastic plate portion 43 is disposed so as to face the inner wall 16A. In the embodiment, the click protrusion 42 is disposed on the upper portion of the outward surface 23A. Therefore, the outward surface 23A is parallel to the outward surface 23A. The slit 44 is formed by cutting from the upper surface direction of the lid 4 to the hinge shaft hole 39 on the inner side, that is, at the center side of the rotation center axis 37. The elastic plate portion 43 has a reverse U-shaped side surface between the slit 44 and the outward surface 23A, both base ends thereof are fixed, and a distal end is formed at a free end.

  Next, the effect | action is demonstrated about the said structure. In the closed state shown in FIGS. 2, 4, and 5, which is the locked state of the lid body 4, the second male screw 30 is engaged with the second female screw 29, so that both are locked. The lid 4 is fixed to the main body 11, and the elastic ring 27 is brought into contact with the upper part of the lower cylindrical portion 14, so that water is stopped. In this closed state, the second cylindrical portion 26 enters the position where the short cylindrical portion 26 faces the inner surface of the lower cylindrical portion 14, and the ring member 20 is fitted to the tapered cylindrical portion 13 from the upper surface side of the lid body. The male screw 30 is engaged with the second female screw 29.

  Further, in this closed state, the hinge shaft portion rotatably supported by the through portion 38 is located at the upper end in the hinge shaft hole 39. Further, the tip of the click protrusion 42 is arranged so as to face the escape recess 41 and is not in contact with the inner wall 16A. Therefore, both surfaces of the slit 44 in the direction of the rotation center axis 37 are arranged in parallel to secure the slit.

  Then, by holding and operating the opening / closing operation disc portion 25, the second male screw in the locked state is rotated by rotating the rotating member 21 as shown in FIGS. By releasing 30 from the second female screw 29, the locking by the screw between them is released. As a result, when the lid 4 moves upward along the central axis 10, the upper end of the ring member 20 is lifted from the upper end of the upper cylindrical portion 12 although the closed state is maintained. A visible step (or protruding appearance) 45 is generated to indicate a loose closed state.

  Further, when the cover body shifts from the latched closed state to the unlocked closed state, the lid body 4 is inclined in the circumferential direction (screw pitch) of the male and female screws due to the release of the latched state. The hinge part shaft 24 moves to the upper end of the hinge shaft hole 39 by rotating around and moving upward along the slope. Further, the tip of the click protrusion 42 is arranged so as to face the escape recess 41 and is not in contact with the inner wall 16A.

  Next, as shown in FIG. 8, which is in the open state, the lid body 4 is opened around the hinge portion 23. At this time, as will be described later, the lid body 4 is moved until the click projection 42 comes into contact with the inner wall 16A. The lid 4 can be rotated while the hinge cover 24 is tilted downward while the hinge 24 is freely moved in the longitudinal direction of the hinge shaft hole 39 while being rotated about the hinge shaft 24. it can.

Then, as shown in FIG. 9 in the fully open state, when the lid body 4 is further rotated around the hinge shaft 24, the click protrusion 42 escapes and climbs over the step between the recess 41 and the inner wall 16A. The protrusion 42 abuts against the inner wall 16A, so that even if the hand is released from the lid body 4, the lid body 4 in which the drinking mouth cover 36 is inclined downward is temporarily fixed at the rotational position. When the leading end of the click projection 42 thus comes into contact with the inner wall 16A, it is elastically deformed so that the elastic plate part 43 fall toward the center of the hinges accept part 16 narrows the width of the slit 44 by the contact force, Due to the restoring force of the elastic plate portion 43, the outward surface 23A comes into pressure contact with the tip of the click projection 42. As a result, the pressure contact force between the click projection 42 and the outward surface 23A is improved, and the temporary fixing force is applied to the relatively large lid 4. Can be demonstrated with Further, even when the click protrusion 42 is rotated inward (bottom plate 32 side) beyond the inner end of the inner wall 16A, the elastic deformation of the click protrusion 42 is eliminated, and the direction of the axis 37 of the pair of left and right click protrusions 42 Since the width of the protruding length is larger than the width between the pair of left and right inner walls 16A, the click protrusion 42 is locked to the edge of the inner end of the inner wall 16A, and the lid is rotated in the return direction (closing direction). It is regulated and the temporary fixing of the fully open state of the lid can be maintained.

  Next, by holding the container 1 with a hand and attaching the mouth to the drinking mouth 18 and tilting the container 1, the beverage contained in the container is passed through the liquid injection hole 33 and the lower cylindrical portion 14 and the upper cylindrical portion 12 are moved. It is possible to reach the peripheral wall portion 17 through. At this time, it is not only possible to put a mouth on the hinge part 23 side, but it becomes an obstacle when drinking, so when grasping the container 1 by hand, the front side located on the opposite side of the hinge part 23 around the central axis 10 is The container 1 is tilted downward so as to be on the lower side.

  At this time, the flow of the beverage in the container 1 is the appropriate flow rate from the liquid injection hole 33 by the opening area of the first process flow path 15A and the liquid injection hole 33 that prevent a large amount of outflow when hitting the middle bottom plate part 32A and the connecting bridge part 34. The second stroke flow path 15B for flowing out the proper flow rate that flows out of the bottle, and further, all or a part of the beverage flowing out from the liquid injection hole 33 hits the second female screw 29 projecting inward and flows to the gap 31 side. By passing through the third stroke flow path 15C for adjusting the flow width so that the width of the water flow, that is, the width of the water column is about 31, and through the fourth stroke flow path 15D of the outflow flowing out from the peripheral wall portion 17 It is. When such a beverage flows out, an air introduction path 46 for introducing air into which outside air flows into the container 1 is formed by the liquid injection hole 33 on the hinge portion 23 side that is not blocked by the beverage.

As described above, in the embodiment, by the action of connecting bridge portion 34 as a partition during outflow, together with the beverage outlet is separated into two collides with the communication fault bridge portion 34, the momentum of the outflow is inhibited .

  In addition, what is necessary is just to perform reverse operation with the above-mentioned opening operation | movement, when closing the cover body 4. FIG.
