[Industrial applications]

 The present invention relates to a container with an inner stopper that also serves as a nozzle.

[0002]

[Prior art] [Problems to be solved by the device]

 The container body that erects the mouth and neck, the inner and outer double cylinders that hang down from the lower end of the screw cylinder with nozzle to the inside and outside surfaces of the mouth and neck through the wall part, and the inner plug that also serves as the nozzle, above. It consists of a cap with a screw cylinder hanging from the outer circumference of the top wall screwed onto the outer surface of the screw cylinder. Plate-closed containers are widely known.

The above-mentioned conventional container is used by removing the cap and opening the horizontal plate that closes the inner surface of the nozzle by pulling up the pull ring, but after use, it is capped again or the whole is discarded until it is removed. .

Recently, the reuse of resources has been demanded, but it is necessary to surely perform disinfection and cleaning for the reuse, and for that purpose, it is necessary to remove the inner plug from the container body. Will be needed. However, since the inner stopper is intended to ensure the tightness of the container, it is easily fitted so as not to come off from the mouth and neck of the container. It will be necessary.

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

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the container of the present invention is hung from the container body 2 standing up the mouth / neck portion 6 and the inner and outer surfaces of the mouth / neck portion 6 from the lower end of the screw cylinder with nozzle 8 to the outside through the wall portion 9. A nozzle-combined inner plug 3 fitted with an inner-outer double cylinder 10 and a peripheral wall 20 covering the outer circumference of the outer cylinder 10b and fitted in a vertically slidable manner. A flange 21 extends inward from the upper end edge. Along with the reinforcing ring 4, the lower surface of the flange 21 is placed on the upper surface of the overhanging wall portion 9, and the lower end of the flange 21 is suspended from the upper end of the peripheral wall 24. The inner plug 3 is made of a soft synthetic resin material, and a plurality of deep grooves 16 are vertically provided in the outer cylinder 10b so that the bottom of the groove 16 can be stretched and deformed. Alternatively, it is configured as a rupturable thin portion 17.

[0007]

[Action]

 When the cap 5 is unscrewed and the pull ring 15 is pulled up, the nozzle 7 is opened and the contents can be poured out. The cap 5 is screwed again while the contents remain.

When removing the inner plug 3 from the neck 6 of the container body after using the contents of the container body, after pulling out the reinforcing ring 4 and removing it, use an appropriate jig such as a screwdriver. Then, if the lower end of the outer cylinder 10b is pushed up, the thin portion 17 at the bottom of the deep groove 16 extends or breaks, and the diameter of the lower part of the outer cylinder 10b increases, so that the inner plug 3 can be easily removed.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which reference numeral 1 shows a container with an inner stopper that also serves as a nozzle. The container 1 is composed of a container body 2, an inner stopper 3, a reinforcing ring 4, and a cap 5.

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

The inner plug 3 is made of a soft synthetic resin, and includes an inner cylinder 10a and an outer cylinder 10b, which are formed from a lower end of a screw cylinder 8 with a nozzle 7 and an outwardly projecting wall 9 to form a double cylinder part. 10 is suspended, and the tubular portion 10 is fitted to the inner and outer surfaces of the mouth / neck portion 6. The lower end of the nozzle 7 is closed by a horizontal plate 11, and a thin wire 12 is provided near the outer periphery of the horizontal plate 11 to form an inner surrounding portion as a removing plate portion 13, and a connecting rod from a side portion of the removing plate portion 13. 14 is erected and a pull ring 15 is laid horizontally on the upper end.

In the present invention, an appropriate number of deep grooves 16 are vertically provided in the outer cylinder 10b, and the bottom of the grooves 16 is formed as a thin portion 17 capable of being stretched and deformed or broken. In this embodiment, the deep groove 16 is formed on the inner surface of the outer cylinder 10b from the outer position of the protrusion 18 of the container body neck 6 fitted to the lower end to the inner surface of the outer cylinder 10b. It may be drilled from the upper end to the lower end. Further, the deep groove 16 may be provided at the same position on the outer surface of the outer cylinder 10b. Reference numeral 19 is an engaging protrusion for engaging the lower surface of the protrusion 18 of the container neck 6 to prevent the inner plug 3 from coming off. Further, if the flange 27 is provided at a predetermined lower position on the outer surface of the neck portion 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 inwardly from the upper end edge of the peripheral wall 20 which is fitted by covering the outer periphery of the outer cylinder 10b. 21 The lower surface is placed on the upper surface of the outwardly projecting wall portion 9 and attached to the inner plug 3. Further, a large number of vertical protrusions 22 in the circumferential direction are vertically provided on the inner surface of the peripheral wall 20, and engage with the vertical protrusions 23 provided in the circumferential direction on the outer periphery of the outer cylinder 10b to prevent mutual rotation in the circumferential direction. In addition, the inner stopper 3 is fitted so that it can be pulled out upward.

The cap 5 is made of a synthetic resin such as polypropylene. The cap 5 is in contact with the inner peripheral edge of the upper surface of the flange 21 of the reinforcing ring 4 while the lower surface thereof is in contact with the outer peripheral portion of the screw cylinder 8. It has a peripheral wall 24 joined together, and a top wall 25 extends from the upper edge of the peripheral wall 24. In addition, a seal tube portion 26 that is fitted in a liquid-tight manner on the inner surface of the nozzle 7 is provided vertically from a predetermined position in the center of the back surface of the top wall 25.

[0016]

[Effects of the Invention] As described above, the container of the present invention has the above-described configuration. Therefore, when removing the inner plug that has used up the contents, after pulling up the reinforcing ring upward, the thin portion at the bottom of the deep groove is removed. The outer cylinder can be enlarged by stretching or breaking the outer cylinder, which makes it easy to remove.

Further, while the content remains, there is no fear that the thin deep groove will be deformed or broken due to the presence of the reinforcing ring and the inside plug will be inadvertently removed by an external force. is doing.
