Description

[0001]
BACKGROUND OF THE INVENTION
This invention has an operating part inserted into a valve stem protruding from the upper end of the can of the aerosol container, and a lower end of the peripheral wall fitted to the mount at the upper end of the can so as to cover the entire operating part from above. The present invention relates to a trigger type aerosol cap configured such that a cap portion including a covered cover portion can be easily removed.
[0002]
[Prior art]
FIG. 1 is an overall external view of an aerosol container 10, where 1 is an aerosol can, 2 is a cap part of a trigger type aerosol cap, 31 is an operation part body, 34 is a trigger part, and 37 is a nozzle part. Reference numeral 7 denotes a virgin seal that is attached so that the operation unit is not moved by mistake during storage or transportation.
[0003]
FIG. 9 shows the cap part 2 taken out, FIG. 10 is a bottom view of the cap part 2 as viewed from below, and 3 is inserted into the valve stem 6 protruding from the upper end of the can 1 to operate the valve stem. This is an operation unit. Reference numeral 31 denotes an operation portion main body, 32 denotes a mounting plate, 33 denotes a mounting rod, and 34 denotes a trigger portion. Reference numeral 35 denotes an insertion portion of the valve stem, 36 denotes a liquid passage in the operation portion 3, 37 denotes a nozzle portion at the tip of the liquid passage, and 38 denotes a spray orifice fitted in the nozzle portion.
[0004]
Reference numeral 4 denotes a cover portion fixed to the mount 5 of the can 1, 41 denotes a holding rib of the mounting rod 33, 42 denotes a holding notch, 43 denotes a cover portion peripheral wall, and 44 denotes a clearance at the lower end of the peripheral wall. In the conventional aerosol cap, since this gap 44 is narrow, even if it is attempted to remove the cap part 2, a tool cannot be inserted , and even if a tool can be inserted, it is difficult to remove only the cap part 2. It was.
[0005]
[Means for Solving the Problems]
For this invention to solve the problem described above, the operation unit, the jetting nozzle portion and a trigger portion which is formed so as to protrude obliquely downward and radially outward at its lower, these portions and the diameter direction are integrally formed with the mounting plate and on the opposite side, and a mounting rod which is provided in a direction perpendicular to the mounting plate in the radial direction end portion opposite to the trigger part of the mounting plate, the mounting A tool for removing only the cover part at the lower end of the peripheral wall of the cover part on the side of the attachment saddle, wherein the scissors are rotatably held in the holding notch at the lower end of the support rib on the rear end side of the cover part. In order to facilitate the insertion and removal operations , a trigger-type aerosol cap is provided in which a gap having a sufficient circumferential length wider than the width of the mounting plate is provided .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
2 is a side view showing the cap portion taken out from the aerosol container shown in FIG. 1, FIG. 3 is a top view of FIG. 2 as viewed from the A direction, FIG. 4 is a bottom view of the same as viewed from the B direction, and FIG. FIG. 6 shows a rear view seen from the direction D, FIG. 7 shows a side sectional view of the state shown in FIG. 2, and FIG. 8 shows a state where the virgin seal can be removed and used. FIG. In each figure, the same reference numerals as those in FIGS. 9 and 10 denote the same parts.
[0007]
In FIG. 2 and FIG. 7, which is a side sectional view thereof, the operation unit 3 is held by the virgin seal 7 so as not to pivot downward with respect to the cap unit 2 , and the trigger unit is accidentally stored or transported. Even if force is applied to the valve 34, the valve stem 6 is lowered by the operating portion 3 so that injection is not performed. As shown in FIG. 8, when the virgin seal 7 is removed, the valve stem fitting / inserting portion 35 and the valve stem 6 are engaged , while the operation portion 3 has the attachment rod 33 engaged with the holding notch 42 of the rib 41. around, pivots counterclockwise by manipulating a finger subjected to the trigger unit 34 the trigger to pull memorial is intended to depress the nozzle stem 6.
[0008]
As can be seen from FIGS. 4 and 6, in the present invention, the gap 45 at the lower end of the cover peripheral wall 43 is wider in the circumferential width than the thickness of the mounting plate so that a tool can be inserted. It is possible to easily remove the aerosol can 1 from the mount 5 by inserting a tool and lifting only the cap portion 2 upward .
[0009]
【The invention's effect】
This invention provides a such of the structure, by wider than the thickness of the mounting plate along the gap between the lower end of the cover peripheral wall of the trigger-type aerosol cap in the circumferential direction, there since the tool can be inserted, aerosol cans It is possible to easily remove only the cap from .
