DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid discharging device, that is, a stopper and a cap for discharging liquid.

[0002]

2. Description of the Related Art As disclosed in, for example, Japanese Patent Application Laid-Open No. 8-198307, a so-called pull-out liquid-ejecting cap with a pull ring is used to secure a sealed state when transporting a container.

[0003] As shown in Japanese Patent Application Laid-Open No. 8-72915, a cap with a nozzle is also known.

[0004]

As described above, both the cap with a pull ring and the cap with a nozzle are conventionally used, but the cap with a pull ring type nozzle is not used.

[0005] The reason is that, in the case of a pull ring type cap or plug, the pull ring is pulled up to remove the plate for removing the closing wall below the ring. It is necessary to open and close with a separately provided auxiliary lid and the like so that it can be opened and closed freely.In the case of a cap with a nozzle or a stopper, the top surface of the main cylinder such as the cap is closed with a top wall, From the upper front surface of the main cylinder, the nozzle protrudes forward by communicating with the inside of the main cylinder, so a pull ring type cap sealing method that requires an opening at the upper end of the main cylinder, a nozzle that needs to close the upper surface of the main cylinder It seems that it could not be adopted for the cap with a stick.

[0006] However, it is needless to say that it is desired to ensure the sealed state of the container at the time of transportation also in the nozzle type cap or stopper.

According to the present invention, an upper end surface of a main cylinder with a nozzle is opened, a sealing wall with a pull ring is horizontally provided on an inner surface of a lower portion of the main cylinder, and an upper end surface of the main cylinder is sealed with a removable lid. ,
This is a pull-out type liquid pouring device with a nozzle.

[0008]

Means for Solving the Problems A synthetic resin material, which is opened at both upper and lower end faces and from the front surface of the main cylinder 2 in which the lower cylinder portion can be attached to the container, communicates with the inside of the main cylinder and projects the nozzle 10 forward. A cylindrical member with a nozzle 1 integrally formed, and a lid 22 integrally formed of a synthetic resin material detachably fitted to the upper end of the main cylinder in a detachable and watertight manner; 1 is a case in which a sealing wall 5 is provided laterally on the inner surface of a main cylinder portion below a base end opening of a nozzle 10, and a thin breaking line 6 is provided on the sealing wall.
Around the sealing wall portion surrounded by the breaking line.
The connecting rod 8 was erected from a part of the outer peripheral edge of the removing plate portion, and a pull ring 9 was attached to the upper end of the rod in a state where the ring was laid horizontally in the upper portion of the main cylinder.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment shown in FIGS. 1 and 2 will be described below. Reference numeral 1 denotes a cylindrical member with a nozzle.
The member has an outward flange 3 at the lower portion of the main cylinder 2 and an engaging ridge 4 around the flange with a small gap below the flange. A sealing wall 5 is provided horizontally on the lower inner surface of the main cylinder 1 to divide the inside of the main cylinder into upper and lower portions, and a thin breaking line 6 is provided on the sealing wall to form a sealing wall portion surrounded by the breaking line. Is a plate portion 7 for removal. Further, a connecting rod 8 is erected from a part of an outer peripheral edge of the removing plate portion, and a pull ring 9 is provided on an upper end of the connecting rod 8 and the ring is
It is attached in a state of being laid horizontally in the upper part.

From the front of the main cylinder above the closed wall 5,
The nozzle 10 protrudes forward so as to communicate with the inside of the main cylinder 2.
In the nozzle, a partition wall 11 is provided laterally above the nozzle except for the inside of the front end of the nozzle where the palate is fitted. To
Each is formed.

The upper end of the main cylinder 2 is used as a fitting portion for a lid, which will be described later.
A concave groove on the inner surface slightly below the upper end to prevent the lid from being pulled out
There are 14 around.

Reference numeral 21 denotes a lid member with a palate, which has a lid 22 which is detachably fitted to the upper end of the main cylinder and is fitted in a watertight manner.
The lid hangs from the outer periphery of the top plate 22a to the outer peripheral wall 22b fitted to the outer surface of the upper part of the main cylinder, and is fitted to the inner surface of the upper part of the main cylinder to form the inner peripheral wall.
Hang 22c. On the outer surface of the lower end of the inner peripheral wall, a ridge fitted into the concave groove 14 is provided. From the rear lower end of the outer peripheral wall 22b, a knob 23 for removing the lid is projected rearward.

An elastic strip 24 protrudes forward from the front lower end of the outer peripheral wall of the lid, and a palate 25 attached to the tip of the strip is attached to the nozzle 10.
Is detachably fitted to the front end portion of the main body. As shown in FIG. 2, when the palate 25 is removed from the front end of the nozzle as shown in FIG. 2, the elastic strip 24 is elastically restored from the bent state when the palate is fitted as shown in FIG. Provide so as not to hinder liquid injection.

Reference numeral 31 denotes a boiler container having a mounting hole in a part of a top wall 32. The lower portion of the main cylinder 2 is forcibly pushed into the mounting hole, and the engaging projection 4 and the outward flange 3 are fitted. The mounting hole peripheral edge portion 33 is fitted in a groove-like portion formed between the watertight and watertight and non-extractable portion.

In the embodiment shown in FIG. 3, the outflow plug type liquid ejection device shown in FIGS. 1 and 2 is replaced with a cap type liquid ejection device, and the main cylinder below the sealing wall 5 and the nozzle 10 is used. The part is formed in the mounting cylinder 26 to the neck of the bottle-shaped container 34.

The cylindrical member 1 with a nozzle and the lid member with a palate
21 are each integrally formed of a synthetic resin material. The lid member 21 with the palate has a shape without the elastic band plate 24 and the palate 25, that is, instead of the lid member with the palate,
Only good.

[0017]

According to the present invention, the main cylinder 2 is provided.
A cylindrical member 1 with a nozzle whose lower inner surface is closed by a sealing wall 5 with a pull ring 9 and whose nozzle projects forward from the front of the main cylinder.
The upper end of the main cylinder 2 is opened, and the lid 22 separately provided on the upper end of the main cylinder is detachably and water-tightly fitted. Therefore, when the container is transported, the sealing wall 5 reliably prevents liquid leakage. At the same time, the lid 22 is removed at the time of use, the removal plate portion 7 is pulled up above the pull ring 9, the removal plate portion 7 is broken off, the sealing wall is opened, and the lid 22 is again fitted to the upper end of the main cylinder. In this way, a convenient pulling-type liquid dispensing device with a nozzle can be obtained. The mouth 22 is attached to the lid 22 via the elastic strip 24, and the mouth is fitted to the tip of the nozzle, thereby preventing dust or the like from adhering to the inside of the nozzle hole.
