[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottle plug.

[0002]

2. Description of the Related Art A bottle body made of polyethylene terephthalate (hereinafter, referred to as "PET") is used for a bottle body for soy sauce or the like, and polyethylene (hereinafter, "PE") is provided at the mouth of the bottle body. ), And a cap made of PE or polypropylene (hereinafter, referred to as “PP”) is detachably attached to the distal end of the inner plug. It is screwed.

[0003] By the way, used bottles of this type are cut by a cutting machine. When the bottles are cut by a cutting machine, if the contents contain salt such as soy sauce, for example,
The salt corrodes the cutting machine and lowers durability.
To prevent this, it is necessary to clean the inside of the bottle body. However, since the opening, which is a spout formed in the inner plug of the bottle body, is small, not only the cleaning liquid injected into the inside of the bottle body cannot be completely discharged after cleaning, but also the injection and discharge of the cleaning liquid. Can not be done quickly so the washing bottle efficiency is poor. In this case, it is sufficient if the inner stopper is removed so that the cleaning liquid can be injected and discharged from the mouth of the relatively large-diameter bottle main body. In order to prevent tampering, the fitting portion at the base end is fitted to the mouth of the bottle body in a state where it is firmly tightened. For this reason, when separating the inner plug from the bottle main body, operations such as cutting and peeling the inner plug with a knife or the like are required, and the work of separating the inner plug is extremely troublesome. As a result, at present, since the cleaning liquid is discharged from the small spout described above, the cleaning liquid cannot be discharged quickly and completely, so that the salt contained in the cleaning liquid remaining in the bottle main body causes corrosion of the cutting machine.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve such inconvenience, and an inner stopper for a bottle body which can quickly and completely efficiently clean a used bottle body. The purpose is to provide.

First, the overall structure of the bottle will be described with reference to FIG. 1. The bottle 1 includes a PET bottle body 2 in which contents such as soy sauce are stored. Bottle body 2
Has a cylindrical mouth 3 at the upper end thereof.
Is fitted with an inner plug 4 made of PE which is an example of the embodiment of the present invention.

As shown in FIG. 2, the inner plug 4 has a cylindrical fitting portion 5 at a base end thereof, and an annular concave portion 6 is formed on an inner peripheral surface of the fitting portion 5. I have. By inserting the annular concave portion 6 into an annular convex portion 7 formed on the outer peripheral surface of the mouth portion 3 of the bottle body 2, the inner plug 4 tightly fastens the mouth portion 3 of the bottle body 2 so that the mouth portion 3 is tightly fastened. 3 is fitted. A cylindrical outer wall portion 8 having a smaller diameter than the fitting portion 5 is continuously provided at a tip portion of the fitting portion 5. On the outer peripheral surface of the outer wall portion 8 of the inner plug 4, a male screw portion 10 to which a cap 9 made of PE or PP is detachably screwed is formed.

In the space surrounded by the outer wall portion 8, a cylindrical spouting portion 11 having a smaller diameter than the outer wall portion 8 is provided with its tip projecting upward from the tip of the outer wall portion 8. . The tip of the pouring section 11 is formed in a shape that warps outward. A plug portion 13 is provided at the bottom of the pouring portion 11 so as to be broken by a score line 12. A pull ring 14 is attached to the stopper 13,
By pulling the pull ring 14 with a finger or the like, the plug 13
Is broken along the score line 12 to form a small opening 15 communicating with the inside of the bottle main body 2. The contents such as soy sauce packed in the bottle main body 2 are poured out from the opening 15. Between the outer periphery of the pouring section 11 and the tip of the outer wall section 8,
As shown in FIGS. 2 and 3, the connecting portions 16 are connected along the entire circumference in the circumferential direction.

The connecting portion 16 has a thin portion 17 which can be broken along the entire circumference in the circumferential direction when the distal end of the pouring portion 11 is pressed inward in the radial direction. As shown in FIGS. 3 to 6, the thin portion 17 has an annular first thin portion 18 formed on the entire back surface of the connecting portion 16 and has substantially equal intervals along the first thin portion 18. And a plurality of (16 in this embodiment) mountain-shaped second thin portions 19 integrally formed with the first thin portions 18 and protruding outward in the radial direction. Second
As shown in FIG. 4, the shape of the mountain of the thin portion 19 is such that the distal ends of the ridge lines 20 a and 20 b on both sides are respectively inwardly inclined, and the distal ends of the ridge lines 20 a and 20 b are linearly connected to each other. The connecting portion forms the top 21.

After the bottle body 1 is used, when the distal end of the spouting portion 11 is pressed radially inward with a finger or the like, the pressing force is firstly applied to the top of the second thin portion 19 according to the principle of leverage. 21 to rupture the top 21 and then break along the ridges 20a, 20b on both sides,
The first thin portion 18 and the remaining second thin portion 19 are broken along the entire circumferential direction. As a result, the connecting portion 16 is broken all around in the circumferential direction to remove the pouring portion 11, and the removed portion has a large diameter communicating with the inside of the bottle main body 2 having a larger diameter than the opening 15 of the plug portion 13. An opening 22 is formed. Therefore, when cleaning the bottle body 1, the cleaning liquid injected into the bottle body 2 can be completely discharged from the large-diameter opening 22.
