[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spout that can be easily removed when reusing a bottle.

[0002]

2. Description of the Related Art For example, as shown in Japanese Utility Model Application Laid-Open No. 4-118348, the lower part of the inner peripheral wall of the inner plug fitted to the outer periphery of the container body so that the stopper fitted to the container body can be easily removed. Is known to be removed along a thin line provided on the peripheral wall.

[0003]

In the above-mentioned prior art, since the gripping piece projects outward from the distal end of the peripheral wall removing portion, the gripping piece impairs the appearance of the container, and another object hits the gripping piece. Could be damaged. The present invention eliminates such disadvantages.

The peripheral wall 2 hanging down from the lower end of the cap fitting tube 9 having the upper part as a discharge tube 11 to the outer periphery of the mouth of the bottle A through an outward flange-shaped annular top wall 7 is attached to the annular top wall. 7 below
A pair of left and right thin break lines 3, 3 are juxtaposed at a proper position inside the peripheral wall 2 with a small gap therebetween in the spout plug fitted with the top surface of the bottle opening abutting on the surface. The peripheral wall portion between the two breaking lines is a break removing portion 12 , and the upper end of the break removing portion is cut off from the other annular top wall portion by a cut 13 provided in the annular top wall 7. Of the annular top wall 7 from the cap peripheral wall 2 to the outer surface of the cap fitting cylinder 9.
When the was fitted, the lower surface of the cap peripheral wall was formed to have a width capable of covering most of the cut upper surface.

[0005]

With the above construction, when removing the bottle A from the mouth Aa, the peripheral wall 2 of the stopper main body 1 is broken open by a break line 3 mechanically or manually to open the bottle mouth. The tightness of the peripheral wall 2 fitted to Aa is loosened. Then, the stopper body 1 may be lightly pulled out thereafter.

[0006]

1 to 3 show an embodiment of the present invention. In the figure, A is a so-called pet bottle, B
Is a breakable opening-type spout with a pull ring fitted and fixed to the mouth Aa of the bottle, and C is a cap removably screwed to the spout, all of which are made of synthetic resin. Consisting of Bottle A is made of a saturated polyester resin,
Injection molding, the body is thinly injected and biaxially stretch-molded, and a locking ridge Ab is provided around the outer periphery of the mouth Aa, and a flange Ad is provided around the outer periphery of the neck Ac. ing. The breakable opening type pouring plug B with a pull ring has a closure wall 4 provided laterally inside the plug body 1, a breakage opening 5 is provided in the closure wall, and a pull ring 6 is integrally protruded upward from inside the breakage opening. are doing. The plug body 1 is appropriately injection molded of synthetic resin, and a peripheral wall 2 that fits on the outer periphery of the bottle opening Aa from the outer peripheral edge of the annular top wall 7 that is brought into contact with the top surface of the bottle opening Aa is vertically provided. A fitting ridge for engaging with the locking ridge Ab is provided around the inner peripheral edge of the peripheral wall, and the fitting fits inside the bottle opening Aa downward from the inner peripheral edge of the annular top wall 7. The cylinder 9 is vertically suspended, the screw cylinder 10 is integrally raised upward, and the upper end of the screw cylinder is once squeezed inward to connect the wide-mouth spout cylinder 11 integrally.
On the peripheral wall 2 of the plug body 1, a pair of left and right thin break lines 3, 3 are juxtaposed at a suitable place inside the stopper body 1 at a small interval, and a gap between the thin break lines is a break removing portion 12, The upper end of the break removal portion is separated from the other by a cut 13 provided in the annular top wall 7. The closing wall 4 is formed in a dish shape corresponding to the pouring cylinder 11 and is integrally connected to a lower end of the pouring cylinder.
A break opening 5 surrounded by a thin break line 14 is provided at an intermediate portion, and a pull ring 6 is integrally protruded from a part of the break opening adjacent to the thin break line 14 via a standing piece 15. .
The cap C is appropriately injection-molded with a synthetic resin. A screw 17 is provided around the inner periphery of the peripheral wall 16 so as to be detachably screwed to the screw cylinder 10. Dispensing cylinder
A stopper tube 19 that fits in the inside 11 is vertically provided integrally. The width of the annular top wall 7 is determined so that the lower end surface of the peripheral wall 16 covers most of the upper surface of the cut 13 provided in the annular top wall 7.

[0007] In the bottle A, contents such as a liquid seasoning are contained in the bottle A and supplied to the market. When the contents are to be poured out by the consumer, the cap C is unscrewed, the pull ring 6 of the breakable opening type spout B with pull ring is pulled up strongly, and the thin break line 14 of the closing wall 4 is broken. Then, the break opening 5 is removed and opened. The bottle A after use of the contents is collected by a contents maker, and the contents maker first removes the old pouring tap B which has been broken open from the mouth Aa of the bottle A. At that time, a force is applied to the upper end of the break removing section 12 at the notch 13 so as to push it open outward, thereby breaking the left and right thin break lines 3 and 3 (FIG. 3). Remove 12 Thereby, the tightness of the peripheral wall 2 is released. Next, the inside of the bottle A is sufficiently washed, and the contents are filled again.
The pull ring 6 of the new break opening type spout B with a pull ring is fitted to the mouth Aa, and is again put on the market.

[0008]

[Effects of the Invention] The present invention has the above-mentioned construction. A pair of left and right thin break lines 3 and 3 are juxtaposed at a proper position inside the spout plug peripheral wall 2 with a small gap therebetween. Is cut off from the other annular top wall portion by a cut 13 provided in the annular top wall 7, and the cut-away portion 12 is removed by using the cut. Thereby, the tightness of the peripheral wall 2 to the opening of the container body can be easily released. The width of the projection of the annular top wall 7 from the cap fitting cylinder 9 is set to a width that allows the lower surface of the cap peripheral wall to cover most of the upper surface of the cut 13 when the cap peripheral wall is fitted to the cap fitting cylinder. In addition, since the thin break lines 3 and 3 are provided inside the peripheral wall 2, a part of the cut 12 is removed in a state where the spout plug is fitted to the opening of the container body and the cap is fitted. Almost hidden, so that the cuts and break lines do not impair the appearance of the container.
