Description

  The invention of the present application comprises a beverage outlet, a lid covering the beverage outlet, a locking means for locking the lid in a closed state, and an opening / closing lever for releasing the locked state of the locking means, and the lid is opened by operating the opening / closing lever. The present invention relates to a structure of a stopper of a beverage container to be opened, and particularly to a structure of a stopper which prevents an inadvertent opening / closing operation of an opening / closing lever.

  In recent stainless steel bottles, a stopper provided with a spout capable of being directly drunk is fitted into an opening on the upper end side of the bottle main body for storing a beverage, and a lid covering the upper part thereof is provided. More.

  The lid is rotatably supported by a pivot such as a hinge provided on one side in the circumferential direction of the plug so as to be able to rotate in the vertical direction. While the part is covered and sealed, the drinking spout and the beverage spout are opened in a state where the part is rotated backward from above.

  The lid is provided with a lock lever for locking the lid in a closed state and an opening / closing lever for releasing the locked state of the lock lever.

  As the opening / closing lever, for example, an easy-to-operate one-push type is often used, and a pressing / rotating lever is provided at the front end of the lid in the front-rear direction of the plug. The lock state of the lock lever is released when pressed rearward (for example, see Patent Documents 1 and 2).

  However, with that alone, when the beverage container is carried in a bag or the like, the opening / closing lever may be inadvertently pressed against something, the lid may be opened, and the beverage may flow out.

  Therefore, recently, a slide-type lock cover member is provided on the opening / closing lever portion, and when carrying, for example, the lock cover member is slid to cover the pressing operation portion of the opening / closing lever so that the pressing operation cannot be easily performed. A safety lock type structure is also provided.

  However, even in the case of the above-described safety lock structure, the condition is that the lock cover member is slid to cover the pressing operation portion of the opening / closing lever, and if the user forgets to apply the lock cover, the state becomes exactly the same as before. Also, there is a risk that the opening / closing lever is inadvertently pressed.

  Further, since the safety lock structure merely slides the lock cover member to cover the pressing operation portion of the opening / closing lever, it comes into contact with other storage items in the bag and receives an external impact. As a result, the lock cover member may slide and the safety lock may be released.

The present invention has been made to solve such a problem, the lock lever to maintain the lid in the closed state, the upward against the lid opening lever downward first pressing operation and the first The lid opening / closing lever can be moved to other storage items in the bag by preventing the lever from being released unless a two-stage operation of the second pressing operation from the front to the rear performed under the pressing operation state is performed. The object of the present invention is to provide a stopper for a beverage container which realizes a reliable safety lock structure which is not easily opened by contacting and receiving an external impact, and which solves the above conventional problems. is there.

  Each of the inventions of the present application has the following effective problem solving means in order to achieve the above object.

(1) Means for Solving the Problems of Claim 1 Means for solving the problems of the present invention include a stopper body having a beverage outlet attached to an opening of a bottle body, and a stopper body on one side in a circumferential direction of the stopper body. is supported, and a lid having a sealing function of the beverage outlet of the arc rotation off vertically, and a lock lever for locking the lid in the closed state, the lid opening lever for releasing the locked state of the lock Kure bar with the door, the lock lever, a first pressing operation for pressing down the lid opening lever from above, under the pressing operation state of the first, second and further pressing the rear of the lid opening lever from the front 2. A stopper for a beverage container configured to be unlocked unless a pressing operation of 2. is performed, wherein the lid opening / closing lever is vertically movable with respect to a vertically movable slide member. Through the pivot And is lowered together with the slide member in response to the first pressing operation from the upper side to the lower side, and is rotated from front to rear in the lowered state in accordance with the second pressing operation. The lock clever is unlocked .

With this configuration, the cover opened closing operation of the cover opening lever is a first pressing operation for pressing down the lid opening lever from above and (safety lock release), under the pressing operation state of the first, the the first pressing operation has become to be performed through the operation of the two stages of the second pressing operation for pressing backward the cap opening lever different in direction from the front (the main lock release), the lid The lid is not opened only by performing the first pressing operation (safety lock release) from above to below on the opening / closing lever . On the other hand , when the second pressing operation from the front to the rear under the first pressing operation state is completed and the lid is opened, the state automatically returns to the original state before the first pressing operation, and is again performed. The state in which the safety lock is engaged (the state in which the second pressing operation cannot be performed unless the first pressing operation is performed) is set.

Also, in the case of this configuration, in the opening and closing lever alone configuration, the first, can be easily realized in the form of successive second pressing operation, other members, such as locking the cover member of the conventional safety lock And no special operation other than the operation of the opening / closing lever such as the operation of setting the safety lock and sliding the lock cover member for releasing the safety lock is required. Therefore, there is no need to forget to apply the safety lock. Therefore, with this configuration, it is possible to realize a secure lock structure and a secure lock function of the lid and the lid opening / closing lever.

Moreover, the safety and locking the first pressing operation for releasing, and the second pressing operation for the main unlocking different in direction from the first pressing operation, the operation of the two-stage motion contiguous to each other It is performed using a single opening / closing lever itself. Therefore, the user first operates the opening / closing lever in the first pressing state from above to below with the thumb or the like, and in the state where the first pressing operation is performed, the thumb or the like directly moves the opening / closing lever from the front to the rear. By operating in the second pressed state, the safety lock can be released, the main lock can be released, and the lid can be easily opened by an operation close to one action without releasing the finger from the opening / closing lever.

  Therefore, it is possible to fully operate with one hand without complicating the operation, while realizing the reliable safety lock function, and realize the original one-push open function by operating only the open / close lever. it can.

Further, in the case of the problem solving means of the present invention, such an opening / closing lever is attached via a rotation shaft to a vertically movable slide member which is always biased and supported in the ascending direction, and is constantly biased in the ascending direction. It is supported and descends together with the slide member in response to the first pressing operation, and in the lowered state, rotates from front to rear in response to the second pressing operation, thereby locking the lock clever. It is designed to be released.

Therefore, according to such a configuration, the vertical opening / closing operation of the opening / closing lever for the safety lock release and the safety lock setting, and the front-back rotation operation of the lid opening / closing lever for the main lock release and the main lock setting are performed. Are realized irrespective of the locked state and the unlocked state of the lock lever. That is, the first pressing downward from above the lid opening lever, the second pressing operation from front to rear, without locking lever-side and mechanical interconnection, respectively, are implemented in an independent form You.

Therefore, the lid opening / closing lever can be moved up and down by the slide member constantly biased and supported in the ascending direction regardless of the locked state of the lock lever and the unlocked state. When the safety lever is lowered to release the safety lock, and further rotated backward by the second pressing operation to release the lock of the lock lever, the slide member automatically returns to the original raised position, and then the lock lever is released. Irrespective of the locked state or the unlocked state, the safety lock is set. Therefore, the safety lock function is further enhanced.

(2) Means for Solving the Problems of Claim 2 According to the structure of the means for solving the problems of the invention, the upper end of the lid opening / closing lever which is always urged and supported in the ascending direction is provided. , Forming a part of the top wall portion of the lid at the ascending position .

According to such a configuration , the above-mentioned first pressing operation of the lid opening / closing lever from above to below can be easily realized by pressing a part of the top wall portion of the lid from above to below.

In the raised position where the cover is not pressed (the safety lock position where the lock of the lock lever cannot be released), since the lid opening / closing lever forms a part of the top wall portion of the lid, when the external shock is applied. , also in a case where hits another storage product in the bag, covered with a large lid top wall portion of the area, is unlikely to occur that only the lid opening lever portion is inadvertently pressed alone.

  As described above, according to the present invention, it is possible to provide a beverage container stopper having a much higher safety lock function than the conventional one.

Like the hinge brackets 53, 53, the plug cover 5 is integrally formed with the horizontal wall 51. As is apparent from the plan view of FIG. 6, for example, the hinge cover 55 includes a top wall portion 71 and a side wall of the lid cover 7 on the outer peripheral surface of the lid, which will be described later, in a locked state in which the lid 6 is closed with respect to the plug body 4. The outer peripheral surface of the portion 72 is formed into a soft curved surface in both the left-right direction and the front-rear direction so as to form an outer peripheral surface that is continuous in a substantially same circle as the outer peripheral surface.

  On the lower surface of the central portion of the top wall portion 61 of the lid 6, a small-diameter tubular drinking-seal packing attaching portion 64 extending downward is provided. A cylindrical first rubber packing portion 66a with a bottom for sealing the beverage outlet 43a of the portion 42, and a flat second rubber packing for sealing the entire tapered opening surface on the upper end side of the drinking mouth portion 42. 66b is detachably fitted from below from a rubber spout packing 66. The planar shape of the lid 6 is a substantially semicircular shape whose outer diameter is enlarged rearward corresponding to the shape of the drinking mouth portion 42 to be covered.

  A flange 62a having a predetermined width is formed integrally with the outer periphery of the lower end of the cylindrical side wall 62 of the lid 6 in the circumferential direction, and the flange 62a is formed using the flange 62a. A lid cover 7 which is an exterior body described below is integrally fitted (forcibly fitted via a force-fitting claw) to the outer periphery of 62a. The lid cover 7 is formed in a perfect circular shape so as to form a regular cylinder having the same diameter as the stopper cover 5 and having a sense of continuity when the lid 6 is closed. Therefore, the outer diameter of the flange portion 62a into which the lid cover 7 is fitted and integrated has a corresponding portion (a U-shaped cutout portion) with the hinge cover 55 (hinge brackets 53, 53) on the rear end side. Except for the parentheses, the shape is basically a perfect circle. The front end side predetermined width portion is, for example, as shown in FIG. 10 and FIG. 17, raised upward, and the lower end side engagement piece 84 a of the lock lever 84, which will be described later, faces downward. In addition, an opening 67 is provided for engaging with the engaging groove 56 provided in the lower part of the drinking mouth part 42.

  For this reason, the opening width of the opening 67 in the front-rear direction is such that the engagement piece 84 a of the lock lever 84 rotates forward of the plug, engages in the engagement groove 56, and rotates rearward of the plug. As a result, the lock is released and is sufficient to be released to the outside of the engagement groove 56.

By inserting and supporting a lever pin 90 between these lever pin support brackets 68, 68, the lock lever 84 is supported so as to be rotatable in the front-rear direction. The lower end side engagement piece 84a of the lock lever 84 faces downward from the opening 67 on the front end side of the flange portion 62a as shown in FIGS.

  A cylindrical boss portion for supporting one end (rear end) of a lock lever lever spring 85 described later in the front-rear direction is provided at a central position between the lever pin support brackets 68 at the front end of the side wall portion 62 of the lid 6. A lock lever lever spring 85 having a predetermined urging strength is provided between the boss portion 69 and the upper-side pressing piece 84b of the lock lever 84 and the back-side convex boss portion 84d to lock the lock lever 84. The engaging piece 84a of the lever 84 is always urged in a direction to be engaged in the lock lever engaging groove 56 on the drinking mouth member 42 side (see the configuration in FIG. 17).

  In this case, the rear end of the upper end side pressing piece 84b of the lock lever 84 is in the locked state of the lid 6, and as is apparent from FIGS. The rearward movement is restricted by the contact, and the opening / closing lever 81 is not pressed vertically downward from the upper side, so that the lock lever 84 is maintained in a stable locked state.

  On both sides of the lever pin support brackets 68, 68 at the front end of the side wall portion 62 of the lid 6, a slide provided with vertical slide grooves 60a, 60a for allowing a slide member 82 to be described later to be slidably and loosely fitted. Member instruction brackets 60, 60 are provided.

  Further, at a portion corresponding to the rear end side hinge cover 55 of the lid 6, a braking member (brake member when the lid is opened) 65 that exerts an effective braking force at the rear end side portion of the hinge cover 55 is provided. I have.

  Further, the lid cover 7 is a shallow cylindrical body provided with a top wall 71 having a circular shape in plan view and a cylindrical side wall 72 extending downward from the outer periphery of the top wall 71 to cover the outer periphery of the lid 6. Opening / closing lever fitting openings 71a and 72a, which will be described later, from the top wall 71 to the side wall 72 at the front end side, and hinge fitting openings 71b from the top wall 71 to the side wall 72 at the rear end side. , 72b are provided, respectively. On the back side of both side walls of the opening / closing lever fitting opening 72a, as shown in FIGS. 14 to 16, for example, there are provided guide grooves 73, 73 for vertically moving the opening / closing lever 81 extending vertically.

  The opening / closing lever 81 can be slid vertically in the opening / closing lever fitting openings 71a, 72a by using the guide grooves 73, 73, for example, before the lid cover 7 is assembled to the lid 6. It is fitted in a state. In this fitting, the pressing portion 81a fits into the fitting opening 71a on the top wall portion 71 side, and the rotating shafts 81c, 81c and the guide ribs 81d on both sides of the cover portion 81b fit into the fitting opening 72a on the side wall portion 72 side. 81d is fitted along the side.

  Then, the lid cover 7 fitted with the opening / closing lever 81 in this manner is provided with the slide member 82, the slide springs 83, 83, the lock lever 84, the lock lever spring 85, the lock lever pin 90, the hinge shaft 54, and the like as shown in FIG. The upper part of the lid 6 to which a hinge spring (not shown) or the like is assembled is fitted and integrated using a flange portion 62a on the outer peripheral side. This forms a lid with an auto-lock mechanism that performs a beneficial action as described below.

  Similarly to the case of the lid 6, the lid cover 7 is formed as a cylindrical body having a tapered surface structure in which the height on the front end side is high as a whole and the height decreases toward the rear end side. A substantially semicircular shape whose outer diameter is enlarged rearward of the lid 6 is provided between the front end of the cylindrical side wall 72 and the front end of the side wall 62 of the inner lid 6. From the shape difference between the (shape corresponding to the mouth part 42) and the round shape of the lid cover 7, a gap of a predetermined size is formed in the left, right, front and rear, and by utilizing this gap, A two-stage motion (two-action) type auto-lock mechanism is provided for setting and releasing the safety lock state, the main lock state, and the respective lock states of the lid opening and closing mechanism for opening and closing the lid 6. Have been.

  As shown in detail in FIGS. 17 and 18, the lock mechanism includes an opening / closing lever 81 that is pressed downward from above and a left / right sliding (elevating) vertically in response to the pressing operation of the opening / closing lever 81. , A pair of right and left slide springs 83, 83 for constantly biasing and supporting the slide member 82 in the ascending direction, and a lock for locking the lid 6 in a closed state and releasing the locked state as necessary. It comprises a lever 84 and a lock lever spring 85 which constantly urges the lock lever in the locking direction.

  As shown in FIGS. 6, 7, and 17 to 19, the opening / closing lever 81 is slightly forwardly formed on a curved surface forming a part of an arc portion at the front end of the top wall portion 71 of the lid cover 7. A pressing portion (pressing operation portion) 81a bulging from above to below and a cover portion 81b forming a part of a circular arc portion at the front end of the side wall portion 72, and pivot shafts are provided on both left and right sides of the cover portion 81b. (Lower) 81c, 81c and guide ribs (upper) 81d, 81d are provided. Then, via the rotating shafts 81c, 81c and the guide ribs 81d, 81d, the cover member 7 is engaged with and supported by a slide member 82 described below in a state in which it can be rotated in the front-rear direction. From the front end of the top wall 71 to the lower end of the front end of the side wall 72, the opening and closing lever fitting openings 71a, 72a, which are long and vertically opened with a predetermined width, are loosely fitted in substantially the same plane, and the guide ribs 81d, 81d are provided. While being guided up and down together with the slide member 82 described below, when the pressing portion 81a is pressed rearward at a position where the pressing portion 81a is pressed downward from above and lowered, the rotating shaft 81c, The lock lever 84 is rotated rearward by a predetermined angle about the rotation axis, and a lock release piece 84b of a lock lever 84 described later is moved rearward against the urging force of the lock lever spring 85. By pressing and tilting, the engagement between the engagement piece 84a of the lock lever 84 and the engagement groove 56 on the drinking mouth portion 42 side is released, and the lid 6 is opened as shown in FIGS. ing.

  That is, in the same configuration, first, the opening / closing lever 81 is pressed downward from above, which swells slightly on the round surface and forms a part of the arc portion at the front end of the top wall portion 71 of the lid cover 7. (A pressing operation portion) 81a and a cover portion 81b forming a part of an arc portion at the front end of the side wall portion 72, and the lid locking state in which the pressing portion 81a is not pressed downward in the vertical direction. In FIG. 21, for example, as shown in FIG. 21, the front end portions of the top wall portion 71 and the side wall portion 72 of the lid cover 7 form mutually continuous portions.

  However, from this state, the pressing portion (pressing operation portion) 81a swelling on the round surface toward the front of the opening / closing lever 81 from the upper side to the lower side is pressed, and for example, as shown in FIG. When the opening / closing lever 71 is lowered to the lower end of the opening / closing lever fitting opening 72a, the state of adjoining the opening end of the opening / closing lever fitting opening 71a of the top wall portion 71 of the lid cover 7 at the rear end of the pressing portion 81a of the opening / closing lever 81 is released. Pushing the unlocking piece 84b of the lock lever 84 rearward of the stopper, for example, as shown in FIG. 23, against the urging force of the lock lever spring 85 urging the lock lever 84 to the locked state. The engagement between the engagement piece 84a of the lock lever 84 and the engagement groove 56 on the drinking mouth portion 42 is released, and the lid 6 can be opened as shown in FIGS. .

  Then, once the lid 6 is opened, the opening / closing lever 81 returns to the original non-pressed state by the urging action of the lock lever spring 85 and the slide springs 83, 83, and automatically locks safely. When the lock 6 is closed, the main lock state by the lock lever 84 is further realized.

  The lower portion of the opening / closing lever fitting opening 72a on the side wall portion 72 side of the lid cover 7 into which the opening / closing lever 81 is loosely fitted is, for example, when the lid 6 is in a locked state, for example, FIGS. As shown in FIG. 17, since the opening / closing lever 81 is located at the upper end side, the opening is opened by a predetermined vertical width (downward stroke dimension), so that the main body front surface 82a of the inner slide member 82 can be seen from the outside. ing. Therefore, when the color of the front surface 82a of the main body of the slide member 82 is changed to red or the like, it can be seen from the color of the same portion that the locked state is established.

  Incidentally, the slide member 82 is composed of an arc-shaped main body member 82a having a predetermined length on the left and right, as shown in FIGS. 18 and 20A to 20C, for example. Bearings 82c, 82c for rotatably fitting and supporting the rotating shafts 81c, 81c on both sides of the opening / closing lever 81 are provided on the upper part of the opening / closing lever 81, and a slide provided on the lid 6 at the outer end. Slide ribs 82d are provided to be loosely fitted in the slide grooves 60a of the member indicating brackets 60.

  Then, by fitting the rotating shafts 81c, 81c on both sides of the opening / closing lever 81 into the bearings 82c, 82c, the opening / closing lever 81 is supported so as to be able to move up and down and to be able to arc backward. The slide ribs 82d, 82d are loosely fitted in the slide grooves 60a, 60a of the slide member indicating brackets 60, 60 via the pair of left and right slide springs 83, 83 at the lower side of the slide member 82. 7, a non-pressed state in which the upper end of the pressing portion 81a of the opening / closing lever 81 in FIGS. 7, 17, and 21 forms the same surface as the outer peripheral portion of the top wall portion 71 of the lid cover 7 ( (The locked state of the lock lever 84).

  On the lower surface side of the slide member 82, first boss portions 82f, 82f into which the upper ends of the slide springs 83, 83 are fitted, and on the flange portion 62a side of the lid 6, the slide spring 83 , 83 are provided with second bosses (not shown) to which lower ends of the slide springs 83, 83 are held.

  As described above, the opening / closing lever 81 can be moved up and down with respect to the vertically movable slide member 82 which is always urged and supported in the ascending direction via the rotating shafts 81c, 81c, and can be rotated in the front-rear direction. It is supported in the engaged state, and is lowered together with the slide member 82 by the above-described pressing operation from above to below in the vertical direction, and in the lowered state, independently presses and rotates from the front to the rear independently of the slide member 82. Thus, the lock of the lock lever 84 is released.

  Then, after the lock is released, when the opening / closing lever 81 is returned to the rear of the plug body by the lock lever spring 85, the opening / closing lever 81 is again moved to the original uppermost end position of the lid 6 together with the slide member 82 by the slide springs 83, 83. It is automatically returned to the safety lock setting state.

  According to such a configuration, the vertical movement of the opening / closing lever 81 for releasing the safety lock and the safety lock, and the turning movement of the opening / closing lever 81 in the front-back direction for releasing the main lock and the main lock are described. Two different operations are realized irrespective of whether the lock lever 84 is locked or unlocked.

  That is, the pressing operation of the opening / closing lever 81 from the upper side to the lower side and the pressing operation from the front side to the rear side are realized in an independent manner without being mechanically linked to the lock lever 84, respectively.

  Therefore, the opening / closing lever 81 can be moved up and down by the slide member 82 which is always biased and supported in the ascending direction by the slide springs 83, 83 irrespective of the locked state and the unlocked state of the lock lever 84. Is released by a first pressing operation from the upper side to the lower side to release the safety lock, and furthermore, the plug member is rotated rearward to release the lock of the lock lever 84 by the second pressing operation. (The slide springs 83, 83) automatically return to the original ascending position, and a state in which the safety lock is set irrespective of whether the lock lever 84 is locked or unlocked. Therefore, the safety lock function is further enhanced.

  In the above-described configuration, the main components constituting the lock mechanism, such as the slide member 82, the slide springs 83, 83, the lock lever 84, the lock lever spring 85, the lock lever pin 90, and the hinge shaft 54, which perform such an operation, are provided. First, a hinge spring and the like are assembled on the lid 6 side, and then the lid cover 7 in which the opening / closing lever 81 is fitted is fitted (forcibly fitted) to the lid 6 to provide a lock mechanism and a hinge spring. Since the lid can be configured, assembly is easy.

  The hinge portion is provided with hinge brackets 53, 53, a hinge shaft 54, and a hinge cover 55 covering the hinge spring, so that the hinge shaft 54, the hinge spring, and the like are not visible from the outside. Therefore, a sense of continuity and a sense of unity with the lid 6 are further improved.

  Further, in the above configuration, the upper end side pressing portion 81a of the opening / closing lever 81 forms a part of the front end portion of the top wall portion 71 of the lid cover 7.

  According to such a configuration, the pressing operation of the opening / closing lever 81 from above to below can be easily performed.

  On the other hand, since the opening / closing lever 81 forms a part of the top wall portion 71 of the lid cover 7, it receives an external impact or hits another stored item in a bag or the like. In such a case, it is unlikely that the lid cover 7 having a large area is covered and only the opening / closing lever 81 is inadvertently pressed alone.

  1 is a bottle main body, 3 is an opening, 4 is a plug main body, 5 is a plug cover, 6 is a lid, 7 is a lid cover, 10 is a plug, 41 is a cylinder, 42 is a spout, and 53 is a hinge bracket. , 56 are lock groove engagement grooves, 81 is an opening / closing lever, 82 is a slide member, and 84 is a lock lever.
