Description

[Detailed Description of the Invention] The present invention is an improvement on the discharge side of a pump injection container or the like.

When storing the discharge side as a set in the top cap, or when handling the discharge side after it has been removed from the valve stem, the discharge side and container are separated, which is extremely inconvenient in terms of handling, such as accidental loss. .

Therefore, in addition to setting and fixing in the normal state during use, the present invention allows the discharge side to be always held integrally with the injection container even if it is removed from the valve stem. The purpose is to simplify and conveniently handle the discharge side that is removed accordingly.

Below, the drawings showing the embodiments of the present invention will be explained.
Figure 1 is a front view of the pump component with the discharge side set upright, Figure 2 is a side view of a part of the pump component with the discharge side sectioned along the line ■-■ in Figure 1, and Figure 3 The figure shows the discharge side removed from the valve stem and fixed to the injection container as an unused set. A is the discharge side, 1 is the button, 2 is the valve stem, and 3 is a screw cap that can be screwed onto the neck of the container body. , 4 is a valve cylinder portion, which acts on the pump component B.

On the discharge side A, a short cylindrical portion 1a is provided on the lower surface of the button 1, so that the valve stem 2 can be fitted and fixed in a socket 5 opening on the lower surface, 6 is a vertical passage continuous above the socket 5, and 1b is a button. A beak-shaped discharge pipe protrudes from the outer periphery, and a horizontal road 7 is provided inside thereof communicating with the upper end of the vertical passage 6, and the outer end thereof is defined as a discharge lower a.

8 is a split elastic piece, and 9 is a fitting recess formed by the split elastic piece 8 and opened in the release direction on the same surface as the release pipe portion 1b.

The split elastic pieces 8 protrude from the outer wall of the short cylindrical part 1a directly below the discharge pipe part 1b at a constant interval 10 between adjacent parts on the same circumference,
A fitting recess 9 having a large diameter and a constant depth for the valve stem 2 is formed inside.

The predetermined adjacent spacing 10 imparts soft elasticity to the divided elastic pieces 8 so that the fitting valve rod 2 can be held therebetween.

The number of adjacent intervals 10 is changed as appropriate.

As shown in FIG. 3, the discharge side A removed from the valve stem 2 hangs down the discharge pipe part 1b along the valve stem 2, and the valve stem 2 is inserted into the fitting recess 9.
The upper end of the set is fitted and elastically clamped by the split elastic pieces 8 to form a fixed unused set.

In this way, when the discharge pipe part 1b is mounted in an upright position as shown in FIG.
When the discharge lower a protrudes outside the screw cap 3, it is convenient to take out the contents, but it has the disadvantage that the top cap cannot be attached, which is inconvenient. When fitting the discharge side A within the diameter range, it is not only necessary to simply fix the discharge side integrally,
It also makes it possible to attach a top cap, increasing the durability and appearance of the product.

FIG. 4 is a front view of the discharge side A showing another embodiment in which the fitting recess 9 is modified, and FIG. 5 is a schematic side view of another discharge side A in an unused set state.

Reference numeral 11 denotes a ring part which is integrally molded under the discharge pipe part 1b, and has a ring hole 12 with a larger diameter than the valve stem 2 inside to form a fitting recess and is fitted into the valve stem 2, as shown in FIG. Form an unused set fixed as shown.

The ring portion 11 may have an endless annular shape, or may have opposing outer ends 11a as shown.

In the latter case, it can be clamped and fixed using soft elasticity.

Furthermore, FIG. 6 shows still another modified embodiment, in which the hole diameters of the discharge lower a and the horizontal passage 7 of the discharge pipe portion 1b are approximately the same as the outer diameter of the valve stem 2.
The valve rod 2 is formed into a radial shape to form a fitting recess into which the valve rod 2 can be freely fitted and removed.

Until now, the convex part protruding from the upper end surface of the pump component B is the valve stem 2.
I have explained it using both.

As another embodiment, although not shown, a modified structure may be adopted in which a small protrusion is integrally provided on the upper end surface of the screw cap 3, and the discharge lower a of the discharge pipe portion 1b is fitted into the small protrusion.

As described above, the present invention provides a convex portion such as a valve stem or a small protrusion on the upper end surface of the pump component, and provides a fitting recess into which the convex portion fits on the outer surface of the discharge side. The discharge side, which is separate from the rod, can be fixed integrally with the injection container other than when mounted upright, making it convenient to handle and having a simple configuration that can expand its use. It has the advantage of being able to be accommodated stably without wobbling when installed, making it a valuable release side for practical purposes.
