Description

[Detailed description of the invention] This invention is a manual fluid dispensing device (so-called sprayer).
Regarding the improvement of parts.

Manual fluid dispensing devices essentially pump up and discharge fluid according to the principle of a pump, and require a stop valve for pumping, and ball valves, plate valves, etc. are used. Many recent products use a member called a spring holder. This has the advantage of making it easier to install the spring, which is difficult to handle, and being able to adjust the amount of discharge at one time.

Nevertheless, manual fluid dispensing devices are constructed from a relatively large number of parts, making their assembly complicated.

The present invention aims to integrate the spring holder and plate valve to reduce the number of parts and simplify assembly work.

According to the invention, there is provided a spring holder for a manual fluid dispensing device, characterized in that the spring holder is integrally formed and connected at its lower end to a stop valve by a flexible or flexible connecting part. provided.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a cross-sectional view of a known manual fluid dispensing device including the improved components of the present invention.

The manual fluid dispensing device includes a cylinder 20, a valve stem 50 partially housed within the cylinder and pushed upwardly by a spring 90, a nozzle piece 60 mounted on the upper end of the valve stem 50, and the cylinder 20.
It consists of a spring holder 70 that is housed in a cylinder and supports a spring with its lower end flange, and upper and lower stop valves 100 and 80. It is fixed to the neck 11. A suction pipe 110 is attached to the lower end of the cylinder. Furthermore, buckets 51 and 52 are formed at the lower end of the valve stem 50.

The cap is provided with an internal collar 41 for supporting the valve stem 50, which is provided with a side hole 42 for introducing outside air into the container, communicating with a side hole 33 provided in the cylinder.

In Figure 2, you can clearly see that the valve stem is pushed down and the outside air inflow path is open.

The manual fluid dispensing device described above and its function are well known and will not be described further.

A feature of the present invention is that the lower end 53 of the plastic spring holder 50, which is supported by the stepped portion of the cylinder, and the stop valve 80 are joined together by a soft or flexible wire member 71 to form one piece. .

The situation is shown in FIGS. 3A and 3B. Third
Figure B shows the view from below. A groove 72 is cut in the spring holder 70 to facilitate the passage of fluid, and the spring holder 70 is connected to a plate valve 80 by a filament 71 and molded integrally.

The present invention reduces steps and significantly simplifies assembly of a manual fluid dispensing device.

[Brief explanation of the drawing]

FIG. 1 is a normal cross-sectional view of a manual fluid dispensing device including a spring holder and a stop valve according to the present invention. FIG. 2 shows the manual fluid dispensing device shown in FIG. 1 with the valve stem depressed. 3A and 3B are side and bottom views of the spring holder and stop valve of the present invention. In these figures, 70... spring holder, 80... stop valve.
