Description

[Detailed description of the device]

[0001]

[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]

 A container body that erects the mouth and neck, and a nozzle-combined inner plug into which the inner and outer double cylinders that hang down from the lower end of the screw cylinder with nozzle through the outward projecting wall are fitted to the inner and outer surfaces of the mouth and neck, It consists of a cap in which the peripheral wall hanging from the outer periphery of the top wall is screwed onto the outer surface of the above-mentioned screw cylinder, and the inner plug that also serves as the nozzle is made of soft synthetic resin, and the inner surface of the nozzle is rupturable with a pull ring. A container closed by a horizontal plate is widely known.

The above 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, the cap is capped again or the whole is discarded until it is removed. .

Recently, it is required to reuse resources, but it is necessary to surely perform disinfection, cleaning, etc. for reuse, and for that purpose, it is necessary to remove the inner plug from the container body. Will be needed. However, in order to ensure the tight sealing of the container, the main body inner stopper is easily fitted so as not to come off the mouth and neck of the container body, and therefore it is troublesome and time-consuming to remove the inner stopper during the above reuse. It was something that

On the other hand, this kind of synthetic resin container is not impossible if the inner plug is forcibly removed. Therefore, the inner plug is removed without opening the nozzle hole, the contents are refilled, and then the inner plug is removed again. There is a possibility that a scandal such as illegal refilling of fitting the stopper may occur.

The present invention solves the above-mentioned drawbacks of the prior art, and proposes an excellent container that can easily remove the inner plug after use and can prevent unauthorized refilling of the contents. Is.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the container of the present invention comprises a container body 2 in which a mouth and neck 5 is erected and a flange 7 is provided around a predetermined position on the mouth and neck 5, and an outer periphery of the mouth and neck 5 above the flange 7. A flange 9 that abuts the upper surface of the mouth / neck portion 5 on the lower surface is extended from the upper end edge of the fitting cylindrical portion 8 fitted through the concave and convex engaging means, and is broken into a screw cylindrical portion 12 erected from the upper surface of the flange 9. From the inner plug 3 that also serves as a nozzle, which is provided with a nozzle 20 whose opening is closed by a possible horizontal plate, and the cap 4 that is detachably mounted by screwing the inner surface of the peripheral wall 23 onto the outer surface of the above-mentioned screw tube portion 12. The inner plug 3 is made of a soft synthetic resin material, and a plurality of deep grooves 14 in the circumferential direction are vertically provided at the lower end of the fitting cylinder 8.

[0008]

[Action]

 If the pull ring 21 is pulled up after the cap 4 is unscrewed, the nozzle 16 opens and the contents can be poured out.

When the inner plug 3 is to be removed from the neck 5 of the container body after the contents have been used, an appropriate jig, for example, a screwdriver or the like is pressed from the outer surface of the lower end of the fitting cylinder 8 to break the bottom of the deep groove 14. At the same time, the inner plug 3 can be easily removed by inserting the jig tip between the lower end of the fitting tubular portion 8 and the flange 7 of the container body 2, and then pushing up the lower end of the fitting tubular portion 8.

When the inner plug 3 is removed, the bottom of the deep groove 14 near the jig insertion part at the lower end of the fitting tubular part 8 is broken, so that the contents cannot be refilled with a normal appearance and illegal refilling is prevented. I can.

【Example】

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

1 to 4 show an embodiment of the present invention, in which 1 denotes a container with an inner stopper that also serves as a nozzle. The container 1 is composed of a container body 2, a nozzle-combined inner stopper 3, and a cap 4.

The container body 2 is made of synthetic resin such as polyethylene terephthalate or glass or the like, and the mouth / neck portion 5 is erected. A locking projection 6 is provided on the outer surface of the upper end of the mouth / neck portion 5, and a flange 7 is provided on the lower outer surface thereof.

The inner plug 3 is made of, for example, a soft synthetic resin such as polyethylene, and has a lower surface that is inward from the upper end edge of the fitting cylinder portion 8 fitted to the outer circumference of the mouth and neck portion 5 and a lower surface above the mouth and neck portion. A flange 9 which is in close contact with the surface is extended, and a seal tube portion 10 which extends downward from the inner peripheral edge of the lower surface of the flange 9 is tightly fitted to the inner surface of the mouth / neck portion 5 so that it cannot be slipped out of the container body 2. ing. Further, a threaded cylinder portion 12 around which a thread 11 is provided is provided upright above the inner peripheral edge of the upper surface of the flange 9.

The fitting cylinder portion 8 is fitted so as not to come out by engaging the locking projection 13 provided at a predetermined position on the upper part of the inner circumference over the lower surface of the locking projection 6 of the mouth / neck portion 5 from above to engage with the locking projection 13. The lower end edge is fitted with the upper surface of the flange 7 of the container body with almost no gap or with a slight gap. Further, a plurality of deep grooves 14 in the circumferential direction are vertically provided on the inner surface of the fitting tubular portion 8 so that the bottom of the grooves 14 can be pressed and broken.

Further, the central portion of the outer periphery of the nozzle 16 in the vertical direction is integrally connected to the inner peripheral edge of the short flange 15 extending inward from the upper end of the screw cylinder portion 12. The nozzle 16 has a cylindrical shape with its upper end spreading like a trumpet, and its lower end is closed by a horizontal plate 17. A thin wire 18 is provided in the vicinity of the outer periphery of the horizontal plate 17, and an inwardly enclosing portion of the thin plate 18 serves as a removing plate portion 19.A connecting rod 20 is erected from the side portion of the removing plate portion 19 and a pull ring is provided at the upper end thereof. 21 are installed horizontally.

The cap 4 is made of a synthetic resin such as polypropylene, and the screw 24 on the inner surface of the peripheral wall 23 hanging from the outer periphery of the top wall 22 is screwed onto the outer surface of the threaded cylindrical portion 12 of the inner plug 3. A seal cylinder portion 25 vertically extending from the central portion of the back surface of the top wall 22 is watertightly fitted to the inner surface of the upper portion of the nozzle 16 and is detachably attached to the inner plug 3.

The container 1 configured as described above presses the tip of the jig 26 such as a screwdriver from the outer surface of the lower end of the fitting cylinder portion 8 at the time of discarding after the contents are used up, for example, as shown in FIG. The inside plug 3 is inserted and removed from the container body 2.

[0019]

[Effect of device]

 As described above, since the container of the present invention has the above-described configuration, the deep groove bottom of the lower end of the fitting cylinder is broken by pressing a jig such as a screwdriver from the outer surface of the lower end edge of the fitting cylinder. The inner plug can be easily removed by inserting the tip of the jig between the tube and the flange of the container and pushing the fitting tube up.

Further, when the inner plug is removed, the breaking portion near the jig insertion portion at the lower end of the fitting tubular portion is broken, so that the contents cannot be refilled with a normal appearance, and illicit refilling can be prevented. ..
