Abstract

(57) [Abstract] [Purpose] So-called PET bottles are widely used in general households, and liquid seasoning containers equipped with a break-opening type pouring stopper with pull ring are well known. Reuse of synthetic resin bottles of this type is being considered from the viewpoint of reducing the amount of materials and saving resources. The simplest method of this reuse is to reuse the bottle itself as is, in this case, in order to thoroughly clean the inside of the bottle and also to open the break-opening type outlet plug with its pull ring. In order to replace it with the old one, it is necessary to remove the old spigot that was already broken and opened. Therefore, when reusing various bottles, it is intended to make it possible to easily remove the old pouring stopper. [Structure] A break line 3 for breaking and opening the peripheral wall 2 of a stopper main body 1 fitted to the outer periphery of a mouth Aa of a bottle A is formed at an appropriate position.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pouring stopper that can be easily removed when reusing a bottle.

[0002]

[Prior art]

 So-called PET bottles are often used in general households, and liquid seasoning containers equipped with a rupturable opening-type pouring plug with pull ring are well known, but in recent years, such as reducing waste and saving resources. From this point of view, the reuse of this type of synthetic resin bottle is being considered.

[0003]

[Problems to be solved by the device]

 By the way, the simplest method of this reuse is to reuse the bottle itself as it is, but in this case, in order to thoroughly clean the inside of the bottle, and in addition, the breakage opening type pouring stopper with the pull ring is used. It is necessary to remove the old spigot that has already been broken and opened in order to replace it with an unopened one. Therefore, the present invention is intended to facilitate the removal of old taps when reusing various bottles.

[0004]

[Means for Solving the Problems]

 To achieve the above object, the present invention is characterized in that a breaking line 3 for breaking and opening the peripheral wall is formed at an appropriate position on the peripheral wall 2 of the stopper body 1 fitted to the outer periphery of the mouth portion Aa of the bottle A. .

[0005]

[Action]

 With the above configuration, when removing the bottle A from the mouth portion Aa, the peripheral wall 2 of the stopper body 1 is broken and opened mechanically or manually at the breaking line 3 to fit the bottle mouth portion Aa. The tight adhesion of the surrounding peripheral wall 2 is loosened. Therefore, after that, the stopper body 1 may be lightly pulled off.

[0006]

【Example】

 1 to 3 show an example of an embodiment of the present invention. In the figure, A is a so-called PET bottle, B is a broken opening type outlet plug with a pull ring fitted and fixed to the mouth portion Aa of the bottle, and C is detachably screwed to the outlet plug. A cap, which is formed by molding synthetic resin. Bottle A has a mouth Aa injection-molded from a saturated polyester resin, a body Ab injection-thin-walled and biaxially stretch-molded, and a locking projection Ab is provided around the outer circumference of the mouth Aa. A flange Ad is provided around the outer circumference of the neck Ac. In the breaking opening type pouring plug B with a pull ring, a closing wall 4 is provided inside the stopper body 1, a breaking opening 5 is provided in the closing wall, and a pull ring 6 is integrally projected upward from inside the breaking opening. is doing. The stopper body 1 is injection-molded from a synthetic resin as appropriate, and a peripheral wall 2 fitted to the outer periphery of the bottle mouth portion Aa is hung from the outer peripheral edge of the annular top wall 7 that abuts on the top surface of the bottle mouth portion Aa. An engaging projection 8 for engaging with the locking projection Ab is provided around the inner peripheral edge of the peripheral wall, and is fitted inside the bottle mouth portion Aa downward from the inner peripheral edge of the annular top wall 7. The fitting cylinder 9 is hung vertically, and the screw cylinder 10 is integrally erected upward. The upper end of the screw cylinder is once squeezed inward, and a wide spout cylinder 11 is continuously connected. Further, on the peripheral wall 2 of the stopper body 1, a pair of left and right thin rupture lines 3, 3 are juxtaposed at appropriate positions inside the plug main body 1 with a small gap therebetween, and the thin rupture lines 12 serve as rupture removal portions 12, The upper end of the fracture removing portion is separated from the other by a notch 13 provided in the annular top wall 7. The closing wall 4 is formed in a dish shape corresponding to the pouring tube 11, is integrally connected to the lower end of the pouring tube, and has a breaking opening 5 surrounded by a thin breaking line 14 at an intermediate portion. A pull ring 6 is integrally projected from a part adjacent to the thin break line 14 in the breaking opening via a standing piece 15. The cap C is injection-molded from a synthetic resin as appropriate, and a thread 17 is provided around the inner wall of the peripheral wall 16 so as to be detachably screwed into the threaded cylinder 10 above the inner surface of the top wall 18. A stopper cylinder 19 that fits into the pouring cylinder 11 is vertically provided integrally.

With the above configuration, the contents such as the liquid seasoning are contained in the bottle A and are put on the market. When the contents are to be poured out by the consumer, the cap C is unscrewed, the pull ring 6 of the breaking opening type discharging plug B with pull ring is strongly pulled up, and the thin breaking plug 14 of the closing wall 4 is broken. The breaking opening 5 is removed and opened. After using the contents, the bottle A is collected by the contents maker, and the contents maker first removes the old pouring stopper B that has been opened from the opening Aa of the bottle A. In that case, at the notch 13, a force is applied to the upper end of the fracture removing portion 12 so as to push it outward, and the thin fracture lines 3 and 3 on the left and right are fractured (Fig. 3). Get rid of 12. As a result, the tight adhesion of the peripheral wall 2 is released, and after that, it can be lightly pulled off. Then, the inside of the bottle A is thoroughly washed, the contents are filled again, and the pull ring 6 of the breaking opening type dispensing plug B with a new pull ring is fitted to the mouth portion Aa, and the bottle A is again put on the market.

FIG. 4 shows another example. In this case, in the breakage-opening type pouring plug B with a pull ring of the previous example, the notch 13 provided in the annular top wall 7 of the plug body 1 is removed and broken. A knob piece 20 is provided so as to project from the lower end of the removing portion 12. Therefore, in order to remove the breakage of the breakage removing portion 12, it is sufficient to pinch the knob piece 20 and apply a force to the outside.

[0009]

[Effect of device]

 According to the present invention, the break line 3 for breaking and opening the peripheral wall 2 of the stopper body 1 fitted to the outer periphery of the mouth portion Aa of the bottle A is formed at an appropriate position, so that the bottle A can be reused. At that time, the breaking line 3 can be broken to easily release the tight adhesion of the peripheral wall 2, and therefore the old pouring stopper having the breaking opening can be easily removed, and the used bottle A Can be effectively reused without any trouble.
