[0007]
DETAILED DESCRIPTION OF THE INVENTION
First, a conventionally known part will be briefly described. Reference numeral 1 denotes an aerosol container. The container body has a large-diameter mouth-neck portion 4 erected from the upper end of the trunk portion 2 via a shoulder portion 3 of the skirt, and an outer peripheral portion of the top plate that closes the upper surface of the mouth-neck portion together with the upper end portion of the mouth-neck portion. It is tightened 5 outward. A stem 6 having a discharge valve at the lower end is passed through the center of the top plate, and the stem is provided so as to be pressed upward so that a small stroke can be pushed down. Liquid can be ejected through the stem by aerosol pressure application.
[0008]
11 is a push-down head in which the lower part of the nozzle communication cylinder 12 is fitted to the upper part of the stem 6, and the push-down head is provided to project the nozzle 13 laterally outward continuously from the upper end of the nozzle communication cylinder, and also serves as the upper part of the nozzle. From the outer periphery of the head top wall 14, the outer peripheral wall 15 is suspended through the nozzle tip.
[0009]
21 is an enclosing cylinder that is erected by fitting the lower cylinder portion to the outer surface of the upper end portion of the container body 1, and the enclosing cylinder is formed into a double cylindrical portion by folding the upper portion downward and inwardly; The upper part of the surrounding cylinder below the nozzle tip is formed in the lower part 22 so that the nozzle can be lowered. The outer peripheral wall 15 of the pressing head described above is fitted into the inner cylinder of the double cylindrical portion so as to be pressed down.
[0010]
In the above configuration, when the push-down head 11 is pushed down to the lower limit together with the stem 6 against the upward bias of the stem 6, the discharge valve provided at the lower end of the stem is opened, and the inside of the stem 6, the nozzle communication cylinder 12, and the nozzle 13 are opened. When the liquid in the container is ejected and the depressing head is released, the depressing head 11 rises to the upper limit together with the stem 6, and the discharge of the liquid is stopped by closing the discharge valve by the stem rising.
[0011]
In the present invention, a first recess 16 provided largely on a part of the outer surface of the pressing head outer peripheral wall 15, a second recess 17 provided continuously to the lower side of the first recess, And a third recess 18 provided independently on the upper side of the recess. As shown most clearly in FIG. 5, the second recess 17 and the third recess 18 are provided outside the opposing side of the first recess 16, but can also be formed outside the same side. is there. Each of these recesses will be described later.
[0012]
The surrounding cylinder portion corresponding to the first recess 16 does not have an inner cylinder, and by vertically forming split grooves 23, 23 from the upper surfaces of the left and right sides of the portion, an elastic engagement plate 24 is formed, and the upper end of the engagement plate The portion is refracted inward, and the inner end portion is used as a fitting protrusion 25. The fitting protrusion is usually provided so as to be located in the lower part of the first recess 16.
[0013]
In the illustrated example, groove-shaped separation lines are provided in the cylindrical wall portion below the engagement plate 24 to erect vertical lines 27, 27 from the left and right ends of the horizontal line 26. The separation line and the upper cylindrical wall portion The cylindrical wall portion that is surrounded by the substrate portion 28 is provided below the elastic engagement plate, and the substrate portion 28, the engagement plate 25, and the space between the substrate portion 28 and the engagement plate 24. An operation plate 29 is formed by the cylindrical wall portion. The operation plate has elastic coupling portions 30 and 30 formed by a gap between the lower end of the split groove 23 and the upper end of the vertical line 27 on both left and right sides of the intermediate portion in the vertical direction.
[0014]
The fitting protrusion 25 of the elastic engagement plate 24 described above is provided so as to be positioned in the lower portion of the first recess 16 as shown in FIG. When the lowering head is pushed down to the lower limit, the inside of the first recess 16 is relatively lifted so as to reach substantially the upper surface of the first recess 16. When the pressing head is released from this state, the fitting protrusion 25 moves relatively into the lower portion of the first recess 16 by the head rising.
[0015]
Further, by turning the pressing head or the surrounding cylinder 21 from this position, the fitting protrusion 25 moves into the upper end of the second recess 17 as shown in FIG. 3, and in this state, the second recess 17 When the upper surface of the tip of the fitting protrusion 25 is engaged with the upper surface, the pressing head cannot be pressed down.
[0016]
Further, from the position shown in FIG. 2, the push-down head 11 is pushed down to the lower limit, and the push-down head or the surrounding cylinder 21 is rotated so that the distal end surface of the fitting projection 25 is elastically deformed by the elastic engagement plate 24. 4, after riding on the outer surface of the non-recessed portion between the first recessed portion 16 and the third recessed portion 18, the elastic engaging plate 24 is fitted into the third recessed portion 18 by elastic restoration as shown in FIG. The pressing head 11 is stopped at the lower limit position. When the operation plate 29 is provided by forming the substrate portion 28 below the elastic engagement plate 24 as in the illustrated example, the outer surface of the non-recessed portion between the first recess 16 and the third recess 18 is fitted. When the projecting portion 25 gets over, the board portion 28 is pushed inward into the surrounding cylinder, and the operation plate 29 can be turned around the elastic connecting portions 30 and 30 to easily get over and over.
[0017]
The first, second, and third recesses 16, 17, and 18, the elastic engagement plate 24, and the operation plate 29 may be provided symmetrically to the left and right facing positions of the pressing head 11 and the surrounding cylinder 21, as shown in FIG. Shows the embodiment. In this case, both the second recesses 17 and 17 can be turned by turning the push-down head or the surrounding cylinder 21 from the state in which both the fitting protrusions 25 and 25 are both in the lower portions of the first recesses. From the state where both fitting projections 25 are located in the upper portions of both first recesses by pushing down the lowering head, both fitting projections are turned by turning the lowering head or the surrounding cylinder. Both parts are provided so that they can be fitted into the third recesses 18, 18.
[0018]
In the configuration described above, when the liquid in the container is ejected, the push-down head 11 may be operated with the fitting protrusion 25 positioned in the lower portion of the first recess 16 as shown in FIG. As shown in FIG. 3, the fitting projection 25 is moved into the upper portion of the second recess to lock, that is, the push-down operation of the push-down head is disabled. After the liquid in the container is exhausted, the push-down head is stopped at the lower limit position by fitting the fitting protrusion 25 into the third recess 18 as shown in FIG. Discard after release.
[0019]
【The invention's effect】
Since the present invention is configured as described above, the lock state in which the push-down head cannot be pushed down by being formed as in claim 1 and the discharge of residual gas after the liquid in the container is exhausted are separated. The first, second and third recesses 16, 17 and 18 are provided on the outer surface of the pressing head outer peripheral wall 15 and can be fitted in a state in which the pressing head can be pressed down. Since the protrusion 25 is provided so as to be positioned in the lower portion of the first recess 16, the upper portion of the first recess 16, the upper end of the second recess, and the third recess 18 can be seen from the outside. Therefore, the locking operation and the gas venting operation are facilitated.
[0020]
According to the second aspect, it is easy to cause the pressing head to descend and rise with respect to the surrounding cylinder 21 while maintaining a horizontal state.
[0021]
In particular, the fitting protrusion 25 can be easily moved from the upper portion of the first recess 16 into the third recess 18.
