Abstract

<P>PROBLEM TO BE SOLVED: To prevent a finger from entering the root of an operating lever section when operating a trigger-type atomizer cap. <P>SOLUTION: The operating section 3 of an atomizer cap has a jetting cylindrical section 31, a mounting plate 32, an operating lever section 34 functioning as a trigger, a nozzle stem inserting/fitting section 35, a liquid channel 36, a spout section 37 (on which a jetting nozzle or the like is mounted) or the like. A thick section 50 is formed over an upper end portion of the section 34 from a lower side of the section 37. The section 50 does not allow the finger to be put into the root of the section 34. A protrusion may be provided at a lower section of the jetting section and/or an upper end of the operating lever in addition to the thick section, or a finger triggering section may be formed at the operating lever section. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  TECHNICAL FIELD The present invention relates to a so-called trigger type sprayer cap having an operation lever portion for operation called a trigger, which is used for an aerosol type or pump type sprayer container for injecting a composition such as an insecticide. .

FIG. 1 to FIG. 6 show a case where it is configured as an inner aerosol cap of a so-called trigger type sprayer cap. FIG. 1 shows an external view of the overall configuration of the sprayer container 10, and FIG. 2 shows a section of the sprayer cap 2 in section. In the figure, the sprayer cap 2 is attached to the upper end of the container 1 of the sprayer container 10. The sprayer cap 2 includes an operation unit 3 and a cover unit 4. As shown in FIG. 2, the cover portion 4 is attached to a mount 5 at the upper end of the container 1. The operation portion 3 is inserted into a nozzle stem 6 protruding from the upper end of the container 1 and is pivotally supported by the cover portion 4 so as to be swingable.
3 is a side view showing the operation unit 3 taken out, and FIG. 4 is a plan view of FIG. 3 as viewed from the direction A. In the operation unit 3, 31 is a barrel part, 32 is a mounting plate, and 33 is a mounting rod. , 34 is an operation lever portion called a trigger, 35 is a valve stem insertion portion, 36 is a passage of the injection liquid in the injection tube portion, 37 is an injection port portion at the tip of the injection tube portion, and 38 is a spray fitted in the injection port portion. Each orifice is shown. A mounting rod 33 at the tip of the mounting plate 32 of the operation unit 3 is held by a holding notch 42 at the lower end of the rib 41 behind the cover unit 4. When the operation lever portion 34 is pulled like a trigger with a fingertip, the entire operation portion swings counterclockwise about the attachment rod 33.
Reference numeral 7 denotes a virgin seal, which prevents the operating unit from being accidentally moved during storage and transportation before use as in the state shown in FIG.
FIG. 5 shows a state where the virgin seal 7 is removed. FIG. 6 shows that the operation lever portion 34 is pulled with a finger to swing the operation portion 3 counterclockwise, and the valve stem 6 is tilted to eject liquid. It shows where you are. In the figure, reference numeral 39 denotes a root of the operation lever portion 34.
In addition to the examples shown in the drawings, there is also devised a so-called multi-lever type in which the barrel part and the trigger part are separated (see, for example, Patent Document 1), It is not limited.

Japanese Examined Patent Publication No. 3-51468

  In the conventional trigger type sprayer cap as described above, since the operation lever portion 34 is formed directly from the barrel portion 31, when the operation lever portion 34 is pulled with a finger, the finger is the root of the operation lever portion 34. It enters the portion 39 (FIG. 6), and it becomes difficult to operate with a small force. Further, the disadvantage that the chemical liquid sprayed from the spray orifice 38 hangs down easily on the finger is unavoidable.

  In order to eliminate the above-mentioned drawbacks, the present invention eliminates the above disadvantage from the bottom of the nozzle part so that the finger does not enter the base of the operation lever part when the operation lever part of the sprayer cap is pulled with a finger. A trigger-type sprayer cap having a thick part extending over the part, a protrusion provided below the nozzle part and / or the upper end of the operation lever part, or a finger hook part formed on the operation lever part was obtained. Is.

  Since the trigger sprayer cap of the present invention is configured as described above, the sprayer container is used to inject the chemical solution, so that when the operation lever portion is pulled with a finger, the finger does not enter the base portion. Therefore, the lever can be operated with a small force, and since the barrel portion and the finger are separated from each other to some extent, the liquid that is sprayed and dripped does not come on the finger.

FIG. 7 shows the first embodiment, and a thick portion 50 is formed from the lower portion of the nozzle portion 37 of the operation portion 3 to the upper end portion of the operation lever portion 34.
FIG. 8 shows a second embodiment, in which a protrusion 51 is provided below the nozzle part 37. FIG. 9 shows a third embodiment, in which protrusions 52 and 53 are respectively provided below the nozzle part 37 and near the upper end of the operation lever part 34.
FIG. 10 shows a fourth embodiment, and two protrusions 54 and 55 are provided near the upper end of the operation lever portion 34.
FIG. 11 shows a fifth embodiment, and a finger hook 56 is formed at the tip of the operation lever 34. FIG. 12 shows a sixth embodiment, in which a finger hook portion 57 is formed at an appropriate position in the central portion of the operation lever portion 34.
In this invention, the shape of the protrusion, the thick portion, etc. may be any shape such as a square shape or a round shape, and the operator's finger does not enter the base during the lever operation even in the thickness or size. It only needs to be of a certain size, and the number of protrusions may be one or more.

  The trigger type sprayer cap of the present invention is configured as described above, and when the sprayer container is used, when the operation lever part is pulled with a finger, the finger does not enter the base of the operation lever part, so the operation lever can be operated with a small force. The part can be pulled, and even if the sprayed liquid drips, it does not hit the finger.
