Description

[Detailed description of the invention] The present invention relates to an improvement in a stopper that dispenses the liquid inside the liquid container body by operating a lever outside the stopper without rotating the stopper itself screwed onto the liquid container. The purpose is to provide a stopper for a liquid container that allows easy lever operation and does not cause fatigue to the fingers pressing the lever.

Hereinafter, embodiments of the present invention will be described based on the drawings. The liquid container 1 includes a container body 5 having a shoulder member 4 at the upper end of an outer case 3 surrounding a bottomed cylindrical inner bottle 2.
and a stopper 6 that is screwed into the central opening of the shoulder member 4 of the container body.

The shoulder member 4 of the container body has a liquid discharge port 7 at the front end, a handle 8 at the rear end, an opening communicating with the two openings of the inner bottle at the center, and a male thread on the inner circumferential wall forming this opening. is engraved.

Reference numeral 9 denotes a seal gasket interposed between the two openings of the inner bottle and the inner circumferential wall forming the opening of the shoulder member 4.

As shown in FIGS. 1 and 2, the upper part of the handle 8 has a cutout in the center except for the left and right walls. The stopper 6 has a female thread carved into the outer peripheral wall thereof to be screwed into the male thread of the shoulder member 4, an inlet 10 communicating with the opening of the inner bottle 2 at the lower end, and communicating with the inlet 10 at the front end. A spout 11 is provided which also communicates with the liquid discharge port 7 of the shoulder member.

A guide cylinder 12 is vertically provided inside the plug body above the center of the upper wall of the injection port 10, and a through hole is bored at the rear end of the plug body through which the front end of a shaft to be described later is inserted.

Reference numeral 13 denotes a plug cover that covers the top of the plug 6.
The valve body 14 that opens and closes the inlet 10 of the stopper body 6 has a push rod 15 fixed at the center of the upper part, which passes through the guide cylinder 12, and is formed into a substantially inverted T-shape in longitudinal section, as shown in FIG. , are in contact with the lower end of the peripheral wall forming the injection port 10 of the stopper via a packing 16.

The push rod 15 is capable of vertically sliding inside the guide tube 12, and has a catch at the top, which connects the push rod 15 to the injection port 1.
A spring 17 is interposed between the upper wall of 0 and the upper wall of 0.

This spring 17 constantly pushes up the valve body 14, and a gasket 1 is attached to the lower end of the peripheral wall forming the injection port 10.
6 and are in close contact with each other.

18 is a slide rod that slides up and down the push rod 15;
As shown in FIGS. 1 and 2, a shaft contact portion 18a that contacts the front end of a shaft to be described later, a push rod contact portion 18b that constantly contacts the upper end surface of the push rod 15,
A spring receiving portion 18c for receiving one end of a spring, which will be described later, is integrally molded, and can be slid back and forth within the plug body. The rear end of the shaft abutting portion 18a of the slide rod 18 is always located within the plug regardless of the back and forth sliding of the slide rod.

The push rod abutting portion 18b has a thin wall surface and a thick wall surface, and always comes into contact with the tip of the push rod, and as shown in FIG. is closed by the valve body 14, and the slide rod 18 is moved forward by a shaft to be described later, and when the upper end surface of the push rod 15 is in contact with the thick wall surface, the injection port 10 is opened.

A spring 19 is interposed between the front wall of the plug body and the spring receiving portion 18c of the slide rod, and constantly presses the slide rod 18 rearward.

As shown in FIGS. 1 and 2, 20 is a shaft that presses the slide rod forward, and is provided between the rear outer wall of the shoulder member 4 and the upper part of the handle 8, so that it can freely slide forward into the plug body 6. .

As shown in FIG.
As shown in the figure, only when the push rod 15 is lowered by operating a lever to be described later, the shaft contact portion 18a of the slide rod 18 passes through the shoulder member 4 and further through the through hole of the stopper 6.
come into contact with.

21 is a return spring for the shaft 20.

Reference numeral 22 denotes a lever, and as shown in FIGS. 1 and 2, a pin 23 is inserted through the left and right walls of the upper part of the handle 8.
It is attached via the shaft contact part 22.
a and the finger grip portion 22b are integrally molded. The shaft contact portion 22a of the lever 22 is always in contact with the outwardly extending rear end of the shaft.

Reference numeral 24 designates a lever return spring which has one end wound around the shaft abutment part 22a and the other end wound around a pin, and then arranged on the lower wall of the upper part of the handle.

The finger grip portion 22b of the lever 22 is connected to the outer case 3,
It is provided inside the handle between the handles 8.

To pour the liquid in the container body, as shown in FIG. 2, hook the finger of the hand holding the handle 8 onto the finger grip part 22b of the lever 22 and grip it together with the handle 8, and the shaft abutting part 22a of the lever will release. Move to the plug body 6 side via the pin 23, slide the shaft 20 forward against the shaft return spring 21, pass the tip of the shaft through the shoulder member 4 and the through hole of the plug body 6, and slide. The slide rod 18 is further slid forward against the spring 19 while making contact with the shaft contact portion 18a of the rod 18.

Due to this forward sliding of the slide rod 18, the upper end surface of the push rod 15, which had been in contact with the thin wall surface of the push rod contact section 18b, comes into contact with the thick wall surface of the push rod contact section 18b, and resists the spring 17. Then, at the same time, the valve body 14 that was in contact with the inlet 10 is also lowered,
Open the injection port 10.

The liquid can be poured by tilting the container body 5 while holding the lever 22 together with the handle 8.

To close the lever, release your finger from the lever, and the spring 17, spring 19, shaft return spring 21, and lever return spring 24 will release the valve body 14, push rod 15, slide rod 18, shaft 20, and lever 2.
2 return to their original positions, and the inlet 10 and the valve body 14 come into contact with each other and are closed.

As described above, in the present invention, a shaft abutting part and a finger grip part that come into contact with the rear end of the shaft are integrally molded on the rear end of the shaft that slides the valve body vertically via the slide rod. This lever is attached to a pin inserted through the left and right walls of the upper part of the handle, and via this pin, one end is connected to the shaft abutting part and the other end is connected to the lever return spring which is arranged on the lower wall of the upper part of the handle. The finger grip part of the lever is located inside the handle between the outer case and the handle, so the lever can be operated easily and without fatigue.

That is, the liquid can be poured simply by hooking the finger of the hand that is placed on the handle onto the finger grip part of the lever and gripping the handle together, and the pouring of liquid can be stopped by removing the finger from the finger grip part of the lever.

Moreover, the lever is operated in accordance with the natural movement of the fingers on the side of the hand that grips the handle, so there is no need to apply any force at all, and the fingers do not feel fatigued when operating the lever. Can be poured.

Furthermore, since the tip of the push rod is always in contact with the slide rod, the injection port can be reliably opened and closed as the slide rod slides back and forth. Furthermore, the rear end of the shaft is always in contact with the shaft abutting part of the lever, which is pivotally supported by a pin, and the lever is equipped with a lever return spring, so the lever can be returned reliably without wobbling back and forth. This makes it more comfortable to use.
