Description

  The present invention relates to a handicap-type liquid container stopper safety structure capable of, for example, pouring a liquid inside by a handle or a container body.

  For example, a handy type liquid container in which a liquid such as hot water is placed inside, such as a coffee server or a thermos bottle, is sealed with a stopper so that the temperature of the contents does not decrease. As such a plug body, a plug body having a structure as shown in FIG. 17 has been proposed.

  The plug body 1 shown in the figure has a canopy 2, an operation lever 3, an inner plug 4, a valve member 5 and the like, and is assembled as one unit. The opening 7 is formed in an opening 7 of a liquid container 6 such as a coffee server or a thermos bottle. The inside of the liquid container 6 is detachably attached in such a manner that the internal thread 8 and the external thread 9 of the outer periphery of the plug body 1 are screwed together, and the liquid container 6 is hermetically sealed.

  Then, when the liquid container 6 is lifted by holding the handle 10 and the operation lever 3 is pushed down with the thumb as shown by the arrow and the liquid container 6 is tilted, the contents pass through the discharge passage 11 into the cup or the like from the spout 12. It is poured out (for example, refer to Patent Document 1).

  By the way, in the plug body 1 having such a structure, the engagement with the opening 7 is due to the screws 8 and 9, and it is necessary to provide the female screw 8 on the inner peripheral portion of the opening 7. There arises a problem that the diameter of the screw becomes small, or the contents are attached to the screw portion and need to be cleaned.

  In order to eliminate such an adverse effect, it is conceivable to use a one-touch type engagement means in which a one-touch type attachment / detachment lever is provided on the plug body 1 and the attachment / detachment lever and the opening 7 are locked. However, when such a one-touch type engaging means is employed, the stopper body 1 is pushed into the opening 7 from above by operating the detachable lever in a direction in which the engagement with the opening 7 is released. The plug body 1 is engaged in the opening 7 by this, but there is no problem if the push-in is sufficient, but for example, when the push-in force is insufficient or the plug body 1 is pushed in a tilted state The stopper main body 1 may not be accurately mounted in the opening 7 and a half-locked state in which the engagement between the detachable lever and the opening 7 is insufficient may occur.

  When such a half-locked state occurs, if the user tries to pour hot water without noticing the half-locked state of the plug body 1, hot water may leak from other than the spout 12 and it is dangerous.

JP 2008-168911 A

  The object of the present invention is to solve such a problem, and when the stopper main body and the opening are not sufficiently locked, the operation lever in a state where the stopper main body and the opening are sufficiently locked is provided.

  When the plug body 40 is attached, the reverse operation is performed, so that the detachable lever 92 in FIG. 1 is not operated, that is, the detachable lever 92 does not overlap the operating lever 80 in plan view.

  The stopper main body 40 is operated so that the two knob members 93 of the detachable lever 92 overlap with the operation lever 80 when the stopper is opened. The knob member 93 can be disposed in the vicinity of the center, the size of the detachable lever 92 in the radial direction can be reduced, and the entire plug body 40 can be downsized.

  An example in which the stopper body 40 is applied to a portable container is shown in FIG. FIG. 16A shows an example of a mug bottle, and FIG. 16B shows an example of a direct bottle. The detailed description is the same as that described above, and will be omitted.

  By the way, the one-touch type plug body 40 as described above is a type that is pushed into the opening 25 from above, and the pushing force is insufficient, or the plug body 40 may be inserted in an inclined state, When pushed in such a state, the locking claw 95b of the detachable lever 92 is not sufficiently inserted into the claw locking groove 33 of the shoulder member 27, and the locking between the plug main body 40 and the opening 25 is inadequate. Sufficient cases may occur.

  FIG. 14 shows such a state. In the figure, an example of insufficient locking is shown so that the left side is sufficiently locked and the right side is circled. As shown in the figure, the knob 93 is not positioned below the operation lever 80 when the left side is sufficiently locked. That is, the knob 93 is positioned below the operation lever 80 in a state where the right side is not fully latched (half-locked state). Therefore, when the user operates the operation lever 80 as usual, the operation lever 80 comes into contact with the knob member 93. As a result, the user can indirectly know that it is in an abnormal state, that is, that the plug body 40 is not sufficiently mounted. Therefore, it is possible to prevent an adverse effect that occurs when pouring hot water in a semi-locked state.

  In the state shown in FIG. 14 described above, the operating force of the operating lever 80 (that is, in a normal state) when the locking claw 95b of the detachable lever 92 and the claw locking groove 33 of the shoulder member 27 are sufficiently locked. The operation lever 80 cannot be operated in the opening operation by the operation force.

  However, when the operating lever 80 is pushed down with a force F larger than the operating force in the normal state as shown by the white arrow in the figure, the plug body 40 is pushed downward, and the locking claw 95b is moved by the spring 94. Since it is pushed left and right, it enters the claw locking groove 33. As a result, the stopper main body 40 is sufficiently attached to the opening 25 and the detachable lever 92 is sufficiently locked to the opening 25.

  The present invention is not limited to the configuration of the above-described embodiment, and can be appropriately changed in design without departing from the gist of the invention.
