Description

  The present invention relates to a trigger type ejector.

  Various types of trigger-type ejectors are known in which a dispenser with a trigger is attached to a container body, and the liquid in the container body is ejected in the form of a mist, foam, or water column by a trigger operation. As a general form of these, the dispenser is fixed to the container body with a mounting cap screwed to the mouth and neck, and the trigger is suspended from the lower front portion of the main body extending on the mounting cap. The liquid in the container is sucked up by the action of the built-in pump mechanism by pulling in the trigger, and the liquid is ejected from the nozzle outlet fitted in the front part of the main body. (Patent Document 1)

In this type of conventional ejector, for example, the upper portion of the body portion of the container body is formed to have a small diameter, and the entire gripping portion is held, and the trigger operation is performed with one index finger or two fingers of the index finger and the middle finger. The length of the trigger is generally around 60 mm in consideration of the width of one or two fingers to be applied when the trigger is operated.

On the mounting cap 11, a main body portion 14 including a cylinder 13 that controls a pump mechanism is provided, and a trigger 15 is suspended from the front portion of the main body portion 14. In addition, a nozzle 16 is fitted to the front end of the main body 14, and a spout 17 is opened on the front surface thereof. The dispenser B can eject the liquid in the container into a liquid column shape, a foam shape, a mist shape, or the like by selecting a known pump mechanism incorporated therein and selecting an internal structure of the nozzle.

The trigger 15 is pivotably mounted with the upper end pivotally attached to the main body 14 and is configured to suck up and eject the liquid in the container body A by the action of the built-in pump mechanism by operating the trigger 15. ing. In the present invention, the trigger 15 includes a trigger body 18 and an extension cover 19.

  The trigger main body 18 is suspended in front of the container body A so as to be swingable, and a pivot base 20 at the upper end is pivotally attached to the main body 14. In the illustrated example, the pivot base 20 has side walls 20b extending rearward from both sides of the front wall 20a as shown in FIG. 6, and pivot shafts 21 projecting from the outer surfaces of the side walls 20b. Further, a rod-like protrusion 22 is provided on the rear surface of the front wall 20a, and a plunger (not shown) in the cylinder 1 is pushed in. In addition, a pair of plate-like parts 23 are provided in parallel downward from the pivot base 20. The plate-like portion 23 is curved so as to protrude forward as a whole, and a first locking ridge 24 for locking is provided on the outer side of the tip edge of each plate-like portion 23, respectively, on the inner side of the tip edge. A second locking ridge 25 for locking is provided in each case.

  Further, a step 26 for temporary fixing is formed at a predetermined upper position of each second locking protrusion 25, and a locking step 27 is formed at a predetermined lower position of the second locking protrusion 25. is doing. Further, a locking protrusion 28 that can be overcome is provided at a predetermined position above the locking step portion 27. Further, a fitting plate 29 serving as one end of an engaging means described later is provided behind each plate-like portion 23 of the trigger body 18. The fitting plate 29 is erected at a rear position between the plate-like portions 23 from the upper surface of the connection base portion 29 a spanned between the plate-like portions 23. The length of the trigger body 18 is preferably a length similar to that of a general trigger type dispenser, and a length of 57 mm is employed in the illustrated example.

  The extension cover 19 is for fitting the trigger body 18 to extend the length of the trigger, and from the state in which the whole is fitted to the outer surface of the trigger body 18, the extension cover 19 is not fitted with a predetermined width below the lower end of the trigger body 18. The sliding down to the state which extended the joint part is made possible. Moreover, the engaging means S in the said lowered position is provided.

In the illustrated example, the extension cover 19 has a cylindrical shape with a rear end opening provided with a vertically long front wall 30, both side walls 31, 31 and a bottom wall 32, and protrudes forward along with the curve of the trigger body 18.
