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 inner cap, and a cap formed by screwing a peripheral wall hanging down from the outer periphery of the top wall to the outer surface of the screw cylinder.The nozzle and inner plug is made of a soft synthetic resin, and the inner surface of the nozzle is provided with a pull ring. A container closed with a breakable horizontal plate is 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. When the container in which the contents remain is used, the inner stopper is securely fixed to the container, and after the contents are used, the inner stopper is easily removed from the container. We propose a new 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. A nozzle / intermediate plug 3 fitted with an inner / outer double tubular portion 10 hanging down through an overhanging wall portion 9, and a top wall 25 extending from an upper end edge of a peripheral wall 24 screwed to the outer surface of the screw tube 8. The inner plug 3 is formed of a soft synthetic resin material, and the flange 21 extends outward from the upper end edge of the outer cylinder 10b.
A locking cylinder 22 hanging outward from the outer cylinder 10b is integrally extended, and a cylindrical reinforcing ring 4 is fitted between the locking cylinder 22 and the outer cylinder 10b. The stop cylinder 22 is configured to be cuttable by a break portion 23, and a plurality of deep grooves 16 are provided vertically in the outer cylinder 10b, and the bottom of the groove 16 is configured as a thin portion 17 that can be elastically deformed or breakable.

[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 neck 6 of the container body after the use of the contents of the container body, the breaking portion 23 is broken, the locking cylinder 22 is cut off, and then the reinforcing ring 4 is pulled up. After removing it, the lower end of the outer cylinder 10b is pushed up using an appropriate jig such as a screwdriver, and the thin portion 17 at the bottom of the deep groove 16 is removed.
The inner plug 3 can be easily removed because the lower part of the outer cylinder 10b becomes larger in diameter by extending or breaking.

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

FIGS. 1 and 2 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a container with a nozzle and an inner plug. The container 1
Comprises 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 vertically in the circumferential direction on the inner surface of the outer cylinder 10b, and the bottom of the grooves 16 is formed as a stretchable or breakable thin portion 17. In the present embodiment, the deep groove 16 is formed in the portion extending from the lower end of the inner surface of the outer cylinder 10b to the center in the vertical direction. However, the present invention is not limited to this, and may be formed in the portion extending from the lower end to the upper end. Reference numeral 18 denotes an engagement ridge for engaging the lower surface of the ridge 19 provided on the container mouth neck 6 to prevent the inner plug 3 from coming off. In addition, the container body and neck 6
When the flange 20 is provided at a predetermined position below the outer surface, the inner plug 3 can be more easily removed by a jig such as a screwdriver.

A flange 21 extends outward from the outer periphery of the upper end of the outer cylinder 10b, and an engaging cylinder 22 for engaging the reinforcing ring 4 extends integrally below the outer periphery of the flange 21. Has been established. As shown in FIG. 2, the locking cylinder 22 is provided with a break 23 formed of a thin line so that the locking cylinder 22 can be cut off from the outer cylinder 10b. The breaking portion 23 includes an annular portion 23a provided on the inner peripheral edge of the flange 21 and a base end portion 23b that emits one end from the annular portion and reaches the other end to a notch at the lower end of the locking cylinder 22. . The locking cylinder 22 is formed to be relatively thin so as to be easily rolled up at the time of breaking at the breaking portion 23.

The reinforcing ring 4 is formed of a synthetic resin or the like, has a cylindrical shape fitted between the outer cylinder 10b and the locking cylinder 22, and is mounted for the main purpose of protecting the thin portion 17. ing.

The cap 5 is formed of a synthetic resin or the like, and has a peripheral wall formed by screwing an inner peripheral lower part to the outer periphery of the screw cylinder 8.
24, and a top wall 25 extends from the upper edge of the peripheral wall. 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.

[0017]

[Effects of the Invention] As described above, the container of the present invention has the above-described structure, and when the inner plug that has been used up is removed, the locking cylinder is cut off at the broken portion and then reinforced. The ring can be pulled upward, and the thin portion at the bottom of the deep groove can be stretched or broken so that the outer cylinder can be made larger in diameter, 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.

When attaching the inner plug to the container,
First, the reinforcing ring is loosely fitted around the outer periphery of the mouth and neck, and the inner plug is fitted to the mouth and neck before fitting the ring. Engagement can be performed reliably.
