Description

  The present invention relates to a liquid ejector that ejects liquid in a container to the outside.

  As a liquid ejector, one that pulls a trigger to drive a pump mechanism in conjunction with the movement of the trigger to eject the liquid in the container from the nozzle to the outside is known (see, for example, Patent Document 1). ). Furthermore, as a liquid ejector, what presses the head part integrally provided in the piston of the pump mechanism, and the pump mechanism drives and the liquid in a container is ejected outside from a nozzle is known.

  Such liquid ejectors are properly used according to the application to be used. For example, a trigger type liquid ejector is mainly used when a liquid is sprayed over a wide range, such as a deodorant, a cleaning agent, or a disinfectant. On the other hand, the pump-type liquid ejector is mainly used when taking a certain amount of liquid, such as a liquid hand soap, cosmetics or perfume. Therefore, even if the user already has a trigger type liquid ejector, for example, when a liquid hand soap or the like is accommodated in a container, the user needs to purchase a pump type liquid ejector. There is a risk that the type of liquid ejector is wasted.

It is the top view which showed the mode at the time of the non-operation of the liquid ejector to which this invention is applied.

  Hereinafter, a liquid ejector to which the present invention is applied will be described in detail with reference to the drawings. In addition, this invention is not limited to the following examples, In the range which does not deviate from the summary of this invention, it can change arbitrarily.

  As shown in FIG. 1, the liquid ejector 1 to which the present invention is applied is a liquid ejector that is attached to the mouth / neck portion 20 a of the container 20 and ejects the liquid stored in the container 20 to the outside.

  Specifically, the liquid ejector 1 has a cap member 2 that is detachably attached to the mouth and neck portion 20 a of the container 20. The cap member 2 has a space portion that opens downward. Further, on the inner peripheral wall surface of the space portion, there is formed a screw portion 2a that is screwed with a screw portion 20b formed on the outer periphery of the mouth neck portion 20a of the container 20. The cap member 2 is detachably attached to the neck 20a of the container 20 by the screw part 2a being screwed with the screw part 20b of the container 20. The cap member 2 may be detachably attached to the mouth / neck portion 20a of the container 20 by other known techniques.

  In addition, a pump mechanism 4 is provided inside the cap member 2 to suck up the liquid in the container 20 and supply it to the nozzle 3 to eject the liquid to the outside in the form of a mist, foam or liquid. The pump mechanism 4 is a conventionally known pump mechanism. For example, the upper end of the pump mechanism 4 is bent forward, the piston 5 is provided with the nozzle 3 at the tip thereof, and the liquid flows downward toward the nozzle 3 side. In addition to a check valve (not shown) that operates as described above, a suction pipe 6 is suspended from the lower end portion, and a piston 5 is slidably provided therein, and a coil spring ( (Not shown) and a cylinder 7 that urges the piston 5 upward via the coil spring, and an outside air introduction path (not shown) that is formed in the cylinder 7 and supplies outside air into the container 20. ing. Since the pump mechanism 4 is a conventionally known pump mechanism, detailed description thereof is omitted here. Furthermore, as the pump mechanism 4, various conventionally proposed ones can be appropriately selected and employed.

  Further, on the upper surface of the cap member 2, for example, an arm 8 protruding obliquely upward and rearward is provided. Further, the rear end of the trigger 9 is rotatably supported on the upper end of the arm 8 via the first rotation shaft 8a. The trigger 9 is substantially L-shaped, and is provided by drooping a front end operation portion 9a where the nozzle 3 at the tip of the piston 5 is exposed from the opening 10 downward and forward. Furthermore, a bearing portion 9 b that rotatably supports a second rotating shaft 5 c formed on the upper portion of the piston 5 of the pump mechanism 4 is formed in the middle portion of the trigger 9. As shown in FIG. 2, the bearing portion 9b is operated so that the operation portion 9a is pulled, and when the trigger 9 is rotated downward about the first rotation shaft 8a, the rotation is interlocked with this rotation. Then, the piston 5 of the pump mechanism 4 is pushed down to the cylinder 7 side via the second rotating shaft 5c. Therefore, when the operation portion 9a is operated, the trigger 9 causes the bearing portion 9b to push down the piston 5 of the pump mechanism 4 toward the cylinder 7 so that the liquid in the container 20 is ejected from the nozzle 3 to the outside by the pump mechanism 4. .

  Further, the liquid in the container 20 is ejected from the nozzle 3 to the outside on the upper surface of the distal end tube portion 5b which is bent with respect to the proximal end tube portion 5a on the cylinder 7 side of the piston 5 and the nozzle 3 is provided at the distal end thereof. A pressing operation unit 11 is provided. The pressing operation portion 11 is provided such that the shaft portion 11 a is inserted through a through hole 12 formed on the upper surface of the trigger 9, and the head portion 11 b at the tip of the shaft portion 11 a is disposed on the trigger 9. Further, as shown in FIG. 3, the shaft portion 11a of the pressing operation portion 11 is provided with such a length that the trigger 9 and the head portion 11b do not come into contact with each other even when the shaft portion 11a is pressed downward. . Furthermore, the pressing operation part 11 is provided so that the axis of the shaft part 11a and the axis of the proximal end pipe part 5a of the piston 5 coincide. Therefore, the pressing operation unit 11 can efficiently transmit the pressing force to the piston 5. Further, when pressed, the pressing operation unit 11 can prevent the proximal tube portion 5a and the distal tube portion 5b from being bent, and can be prevented from being damaged.

  Further, the through hole 12 formed on the upper surface of the trigger 9 and through which the shaft portion 11a of the pressing operation portion 11 is inserted, as shown in FIG. Even when the trigger 9 is operated to rotate downward, the trigger 9 and the pressing operation unit 11 are provided so as not to contact each other. Here, as shown in FIG. Yes. That is, the pressing operation unit 11 and the trigger 9 are driven separately.

  As shown in FIG. 3, when the pressing operation unit 11 having the above configuration is pressed downward by a user or the like, the piston 5 of the pump mechanism 4 is pushed down to the cylinder 7 side to The liquid in the container 20 can be ejected from the nozzle 3 to the outside.

  The pressing operation unit 11 may be provided integrally with the distal end tube portion 5b of the piston 5 by, for example, an adhesive or press-fitting, and a shaft portion in which a screw portion is formed at the distal end of a screw hole formed in the distal end tube portion 5b. You may make it attach to the front-end | tip pipe part 5b of piston 5 so that attachment or detachment is possible, for example by screwing 11a.

  The liquid ejector 1 to which the present invention having the above-described configuration is applied can cause the pump mechanism 4 to eject the liquid in the container 20 from the nozzle 3 to the outside by operating the operation portion 9 a of the trigger 9. Furthermore, the liquid in the container 20 can be ejected from the nozzle 3 to the outside by the pump mechanism 4 by pressing the pressing operation unit 11. Therefore, the liquid ejector 1 to which the present invention is applied can be used as a so-called trigger type liquid ejector mainly used when spraying a liquid over a wide range, and further, mainly a certain amount of liquid is used. It can also be used as a so-called pump-type liquid ejector that is used in the case of taking only a minute amount. Therefore, the liquid ejector 1 to which the present invention is applied can be used in either usage regardless of the usage, and is economical.

  In addition, the liquid ejector 1 to which the present invention is applied is not limited to the through hole 12 being formed in a long hole shape, and the trigger 9 is rotated downward when the trigger 9 is operated when not operated. As long as it is provided so that the trigger 9 and the shaft portion 11a of the pressing operation portion 11 do not come into contact with each other, for example, any shape such as a circle, a rectangle, or a polygon may be used.

  Further, in the liquid ejector 1 to which the present invention is applied, the pressing operation portion 11 is provided on the upper surface of the distal end tube portion 5b so that the axis of the shaft portion 11a coincides with the axis of the proximal end tube portion 5a of the piston 5. The present invention is not limited to this, and if the pressing operation unit 11 can be pressed, it may be biased and provided on the upper surface of the distal end tube portion 5b.
