  In addition, an ejection nozzle 14 is provided on the side surface of the ejection head 13, and the inside of the container body 1 is connected via the tube 16 by the action of a known pump 17 provided in the mounting cap 11 by moving the ejection head 13 up and down. The liquid is sucked up and ejected from the ejection nozzle 14.

  A pair of rotation stoppers 20 for restricting the ejection head 13 from moving downward are provided on the side surface of the base cylinder portion 12. The rotation stopper 20 includes a first side portion 21 and a second side portion 22 that are arranged in parallel to each other, and a top side portion 23 that connects one ends of the first side portion 21 and the second side portion 22. This is a member formed in a substantially U shape in plan view. As shown in FIG. 1, rotating portions 24 and 25 are provided at the other ends of the first side portion 21 and the second side portion 22, and shaft portions 24 a and 25 a are provided on the inner surfaces of the rotating portions 24 and 25. Each is protruding.

Has been. The pair of rotation stoppers 20 are bearings provided such that the shaft portion 24 a of each first side portion 21 and the shaft portion 25 a of the second side portion 22 are symmetrically located on the side surface of the base tube portion 12. By being pivotally attached to 12a and 12b, respectively, they are supported so as to be rotatable with respect to the base tube portion 12, respectively.

  Further, knobs 27 and 28 each having a substantially semicircular arc shape are formed on the top side portion 23 of the pair of rotation stoppers 20, respectively. The knobs 27 and 28 are formed so as to protrude from the inner surface side of each rotation stopper 20, and the knob 27 formed on one rotation stopper 20 and the knob 28 formed on the other rotation stopper 20 are symmetrical to each other. Is made. Locking pieces 27a and 28a that are detachably engaged with each other are formed at portions where the knob piece 27 and the knob piece 28 face each other.

Next, the operation of the liquid ejection container will be described.
The pair of rotation stoppers 20 are rotated in the closing direction and the opening direction with the rotating parts 24 and 25 on both sides as rotation axes. As shown in FIG. 2, the pair of rotation stoppers 20 can be set in a standing posture (hereinafter referred to as a standing and closed state) by rotating in a closing direction. Also, as shown in FIG. 3, the pair of rotation stoppers 20 can be set in a substantially horizontal posture (hereinafter referred to as a horizontal open state) by rotating in the opening direction. And a pair of rotation stopper 20 can change between these two states as needed.

As shown in FIG. 2, when the pair of rotation stoppers 20 are set in the standing closed state, the locking pieces 27 a and 28 a provided on the pair of rotation stoppers 20 can be engaged with each other to maintain the standing closed state. It becomes. Further, as shown in FIG. 3, when the engagement by the locking pieces 27a and 28a is released, the pair of rotation stoppers 20 can be shifted to the horizontally opened state.

  In the standing closed state shown in FIG. 2, the top portions 23 of the pair of rotation stoppers 20 are disposed above the ejection head 13. For this reason, the ejection head 13 can be made difficult to be pressed. Then, by setting the pair of rotation stoppers 20 in the horizontally opened state shown in FIG. 3, it is possible to press the ejection head 13 and eject the content liquid.

  Here, as shown in FIGS. 1 to 3, the first side portions 21 of the pair of rotation stoppers 20 each have a cover recess 26 that closes the outer side and has an inner side formed as an opening. The configuration described above is preferable. In this configuration, when the pair of rotation stoppers 20 are in the standing and closed state, the ejection nozzle 14 can be wrapped from both sides by the both cover recesses 26. As a result, the ejection nozzle 14 is held by both cover recesses 26 and can be prevented from moving downward in the ejection head 13, thereby making it impossible to press the ejection head 13, and thus the liquid ejection container Even when the bag is carried in a bag or the like, leakage of the content liquid can be reliably prevented. Furthermore, it is possible to protect the tip of the ejection nozzle 14 and prevent adhesion of dust and the like.

  Further, in this case, a protrusion 18 extending in the longitudinal direction (height direction) is provided on the side surface of the ejection head 13, and a locking recess 19 is formed on the upper surface of the base tube portion 12. It is preferable that the recess 19 is engaged. In this configuration, the mounting cap 11 can be prevented from rotating in the circumferential direction, and the ejection nozzle 14 can always be positioned so as to face a certain direction. For this reason, when the pair of rotation stoppers 20 are in the upright closed state, both cover recesses 26 can reliably cover the ejection nozzle 14.

  Furthermore, it is also possible to form a locking recess made of a U-shaped notch on the lower side of the top side 23 on the head of the ejection head 13. When configured in this way, for example, when selling a liquid ejection container containing skin lotion or the like, the liquid ejection container is displayed in a suspended state by locking the locking recess with a wall-hanging hook or the like. It becomes possible and convenient.

Next, a lock mechanism that restricts rotation of the rotation stopper will be described.

Are formed respectively. Further, an upper locking groove 11c and a lower locking groove 11d that are horizontally formed with a predetermined interval in the height direction are formed on the surface of the vertical groove 11a. A locking projection 33 that can be engaged with the locking groove 11c and the lower locking groove 11d is projected. Further, a protrusion 31 that functions as a slip stopper is formed on the surface of the slide member 30.

  As shown in FIGS. 4A and 5A, the state in which the slide member 30 is moved to the lower position in the longitudinal groove 11a is the unlocked state. In the unlocked state, the pair of rotation stoppers 20 can be freely set to a standing closed state and a horizontal open state. In the unlocked state, the locking projection 33 on the slide member 30 side engages with the lower locking groove 11d on the vertical groove 11a side, and the slide member 30 can be held at the lower position in the vertical groove 11a. It has become.

As shown in FIGS. 4B and 5B, after the pair of rotation stoppers 20 are horizontally opened, the protrusion 31 is pushed with the finger to move the slide member 30 upward, and the upper end of the slide member 30 is moved from the upper surface of the mounting cap 11. Further, the locked state is a state in which it is protruded upward and fitted into both notches 29a of the pair of rotation stoppers 20.
In this locked state, the engaging protrusion 33 on the slide member 30 side engages with the upper engaging groove 11c on the vertical groove 11a side, so that the upper end of the slide member 30 protrudes to the upper position in the vertical groove 11a. It is possible to prevent the slide member 30 from moving to the lower position without permission during use. Therefore, in the locked state, the posture in which the pair of rotation stoppers 20 are opened approximately horizontally can be maintained as it is, and the transition to the standing closed state during use can be prevented.
For this reason, as shown in FIG. 6, for example, one of a pair of rotation stoppers 20 in a locked state and a horizontally open state is supported by the index finger and the other is supported by the middle finger, and the ejection head 13 is pushed down by the thumb. It is possible to realize a usage pattern such as jetting.

In the second embodiment, when the pair of rotation stoppers 20 reach the horizontal opening state, the locking projections 29b and the locking recesses 11e engage with each other, so that the posture reaching the horizontal opening state can be maintained. It has become.
In this lock mechanism, for example, in a usage mode in which the liquid ejection container is tilted to discharge the content liquid, the pair of rotation stoppers 20 in the horizontally open state rotate freely against the user's intention and are in the standing closed state It is possible to prevent the operation to return to the state.

FIG. 8 is a perspective view showing another embodiment of the liquid ejection container with a stopper.
In FIG. 8, gears 29 c are formed on the side surfaces of the rotating portion 24 of the first side portion 21 on the side of the pair of rotation stoppers 20. In this configuration, since both the rotating portions 24 rotate while the one gear 29c and the other gear 29c are engaged with each other, the rotation operations of the one rotation stopper 20 and the other rotation stopper 20 can be synchronized. For this reason, it becomes possible to operate the other rotation stopper 20 similarly to one rotation stopper 20 only by operating one rotation stopper 20, and the operability of the rotation stopper 20 can be improved.

  As mentioned above, although the structure of this invention and its effect were demonstrated along the Example, embodiment of this invention is not limited to the said Example.
