BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container with an inner cap which also serves as a nozzle.

[0002]

[Prior art]

SUMMARY OF THE INVENTION A container body erecting the mouth and neck, and an inner / outer double cylinder hanging down from the lower end of the threaded cylinder with a nozzle through an outwardly projecting wall are fitted to the inner and outer surfaces of the mouth and neck. A nozzle and an inner plug, and a cap in which a screw tube hanging down from the outer periphery of the top wall is screwed to the outer surface of the screw tube.The nozzle and inner plug is made of a soft synthetic resin, and the inner surface of the nozzle is pulled. BACKGROUND OF THE INVENTION Containers closed with rupturable transverse plates with knurls are widely known.

The above-mentioned conventional container is used by opening a horizontal plate for closing a nozzle inner surface by pulling up a pull ring by removing a cap, but after use, the entire container is discarded again with the cap closed or removed. .

Recently, there has been a demand for the reuse of resources.
For reuse, it is necessary to surely perform disinfection, cleaning, and the like, and for these, it is necessary to remove the inner plug from the container body. However, in order to ensure that the container is tightly sealed, the inner plug is easily fitted so as not to come off from the mouth and neck of the container body. Therefore, the removal of the inner plug at the time of reuse is troublesome and troublesome. It is what becomes.

The present invention has been made in view of the above points, and the inner plug is securely fixed to the container when the container in which the contents remain is used, and the inner plug can be easily removed from the container after the contents are used. We propose a container with a nozzle and inner stopper that is convenient for reuse of the container.

[0006]

In order to solve the above-mentioned problems, the container of the present invention has a container body 2 standing on the mouth and neck 6 and the inner and outer surfaces of the mouth and neck 6, and from the lower end of the screw cylinder 8 with nozzle outward. From the upper end of the peripheral wall 20 fitted with a nozzle / intermediate plug 3 fitted with an inner / outer double tubular portion 10 hanging down through the overhanging wall portion 9 and fitted vertically slidably to cover the outer cylinder 10b. A reinforcing ring 4 having a flange 21 extending inward and a lower surface of the flange 21 mounted on an upper surface of the overhanging wall portion 9.
And a cap 5 having a top wall 25 extending from an upper end edge of a peripheral wall 24 having a lower end suspended above the flange 21 and screwed to the outer surface of the screw tube 8. The inner plug 3 is made of a soft synthetic resin. A plurality of deep grooves 16 are vertically formed in the outer cylinder 10b.
The bottom portion was formed as a thin portion 17 that can be deformed or broken.

[0007]

When the cap 5 is unscrewed and the pull ring 15 is lifted, the nozzle 7 is opened and the contents can be poured out. While the contents remain, the cap 5 is screwed again.

When the inner plug 3 is removed from the mouth and neck 6 of the container body after using the contents of the container body, the reinforcing ring 4 is pulled up and removed, and then, for example, an appropriate jig such as a screwdriver is used. When the lower end of the outer cylinder 10b is pushed up, the thin portion 17 at the bottom of the deep groove 16 is extended or broken, so that the lower part of the outer cylinder 10b is enlarged, so that the inner plug 3 can be easily removed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a container equipped with a nozzle and an inner stopper. The container 1 includes a container body 2, an inner plug 3, a reinforcing ring 4, and a cap 5.

The container 2 is made of a synthetic resin such as polyethylene terephthalate or glass or the like, and has a mouth and neck 6 standing upright.

The inner plug 3 is formed of a soft synthetic resin. The inner plug 3 is formed of an inner and outer double cylinder formed by an inner cylinder 10a and an outer cylinder 10b via a wall 9 extending outward from a lower end of a screw cylinder 8 with a nozzle 7.
Then, the cylindrical portion 10 is fitted to the inner and outer surfaces of the mouth and neck portion 6.
The lower end of the nozzle 7 is closed by a horizontal plate 11, a thin line 12 is provided around the outer periphery of the horizontal plate 11, and an inner surrounding portion thereof is formed as a removing plate portion 13, and a connecting rod is formed from a side of the removing plate portion 13. 14 is erected, and a pull ring 15 is provided laterally at the upper end thereof.

In the present invention, an appropriate number of deep grooves 16 are provided in the outer cylinder 10b.
And the bottom of the groove 16 is formed as a thin portion 17 that can be deformed or broken. In this embodiment, the deep groove
16 is formed in the inner surface of the outer cylinder 10b so as to extend from the outer position to the lower end of the ridge 18 of the fitted mouth and neck 6 of the container body, and extends from the upper end to the lower end of the inner surface of the outer cylinder 10b. It may be perforated. Further, a deep groove 16 may be provided at the same position on the outer surface of the outer cylinder 10b. Reference numeral 19 denotes an engaging ridge for engaging the lower surface of the ridge 18 of the container body neck 6 to prevent the inner plug 3 from coming off. Further, when the flange 27 is provided at a predetermined position below the outer surface of the neck 6 of the container body, the inner plug 3 can be easily removed by a jig such as a screwdriver.

The reinforcing ring 4 is made of a synthetic resin such as polypropylene, and has a flange 21 extending inward from an upper end edge of a peripheral wall 20 fitted and fitted to the outer cylinder 10b. The lower surface 21 is placed on the upper surface of the outwardly protruding wall 9 and attached to the inner plug 3. Also, a large number of circumferential ridges 22 are vertically provided on the inner surface of the peripheral wall 20 and are mutually engaged with the vertical ridges 23 provided with a large number of circumferential ridges on the outer periphery of the outer cylinder 10b, so that rotation in the circumferential direction is impossible. And, it is fitted to the inner plug 3 so that it can escape upward.

The cap 5 is formed of a synthetic resin such as polypropylene. The lower surface of the cap 5 is in contact with the inner peripheral edge of the upper surface of the flange 21 of the reinforcing ring 4 and the lower inner peripheral portion is screwed to the outer periphery of the screw cylinder 8. A peripheral wall 24 is provided, and a top wall 25 extends from an upper edge of the peripheral wall 24. In addition, a seal tube portion 26 that fits liquid-tightly to the inner surface of the nozzle 7 is vertically provided from a predetermined position at the center of the rear surface of the top wall 25.

[0016]

[Effect of the Invention] As described above, the container of the present invention has the above-described structure. When the inner plug that has been used up is removed, the reinforcing ring is pulled upward, and then the thin portion at the bottom of the deep groove is removed. Can be stretched or broken to increase the diameter of the outer cylinder, and thus can be easily removed.

While the contents remain, there is no danger that the thin deep groove is deformed or broken due to the presence of the reinforcing ring and the inner plug is inadvertently detached by an external force. doing.
