Abstract

PURPOSE:To prevent unrightful unsealing by a device wherein the lid can not be lifted from the spout unless a pull tab for unsealing at the outer lower end of an unsealing piece is raised to break fragile lines in the-left and right sides and disengage a fastening projection at the inner lower end from a fastening ring in the spout. CONSTITUTION:In a mouth cap 100 the outer circular surface in the lower part of a lid 110 is joined with the outer circular surface of a spout 120 with a connecting strap 130 therebetween. In this instance a fastening hollow 125 for the fastening to the wall board 11 of a paper container for liquid is formed in the outer circular side of the lower end of a ring-shaped base 124 of the spout 120 and a cylindrical circular wall 121 having a fastening ring 123 on the outer circular side is erected on the upper end of the ring-shaped base 124. On the outer circular surface of a circular wall 114 at a position opposite to the connecting strap 130 an unsealing piece 116 is provided, which is connected at its upper end to the roof 111 with a hinge 115 therebetween. On the other hand, at the lower end of the unsealing piece 116 a pull tab for unsealing 117 is provided on the outer side and a fastening projection 118 which engages with a fastening ring 123, on the inner side. The left side and right side are joined to the circular wall 114 with the interposition of fragile lines respectively.

ものである。However, the spout which tears and opens the thin fragile wire ring by the above-mentioned tension ring may require unexpected force for a housewife at the time of opening, the tension ring may be damaged, or the opening may be damaged. There were complaints such as liquid leakage when the resealed container was inverted. In addition, recently, mischief in products at stores has become more clever, and even if the appearance is quite normal, for example, the thin weakened ring is partially capped and capped. It was However, the fraud prevention plug of the liquid paper container is still in the development stage and has not been developed for practical use. Therefore, the present inventor
As an issue to solve the following, we have developed a fraud prevention plug for liquid paper containers. The problems are that it has a virgin function, that even if it is once opened, it can be recognized clearly even if it is reopened, it is easy for a housewife to open, and after opening, liquid leakage occurs when reopened. There was no structure. The present invention provides a tamper-proof plug for a liquid paper container that sufficiently solves the above problems.

容易に行うことができた。[0012] Next, the prepared plug is projected on the top opening of the sleeve (blank folded on the back) of the liquid paper container, and is heat-sealed by the ultrasonic sealing method. Load the attached sleeve into the liquid filling machine, and
After the sealing step, a liquid paper container (10) having the tamper evident opening stopper (100) of this embodiment shown in FIG. 2 attached to the peripheral wall plate (11) at the top was prepared. The stopper of this embodiment attached to this liquid paper container has a spout part fixed to the container, a lid part, and a locking projection provided on the inside of the lower end of the unsealing piece as a locking ring of the spout part. It was engaged and firmly fixed. This lid portion had a virgin function because the lid portion could not be removed from the spout portion unless the lines of weakness on both the left and right sides of the unsealing piece were cut. Next, pull up the opening knob provided on the outside of the lower end of the unsealing piece upward, cut the weak lines on both the left and right sides of the unsealing piece, remove the lid from the spout portion, open the container, and then open the lid again. The part was fitted to the spout part. Once the mouthpiece was opened, the lines of weakness on both the left and right sides of the opening piece were cut, so it was clearly and easily recognized that it was opened. Furthermore, the container with the mouth plug resealed was left standing upside down for 24 hours, but no water leakage occurred. The fragile lines on both the left and right sides of the unsealed piece could be easily cut by the housewife.

必要な強度に合わせて設定することができる。The tamper evident opening stopper for a liquid paper container according to the present invention has a spout portion projecting from and fixed to a peripheral wall plate of a liquid paper container, and a lid portion connected by a connecting band is attached to the spout portion. A locking projection provided on the inside of the lower end of the unsealing piece provided on the outer peripheral surface of the peripheral wall of the lid portion facing the connecting band engages with a locking ring of the spout portion and is fixed to the spout portion. Therefore,
Pull up the opening knob on the outside of the lower end of the opening piece,
The lid part cannot be removed from the spout part unless the weakening lines on both the left and right sides of the unsealing piece are cut and the locking projection inside the lower end is removed from the locking ring of the spout part. For this reason, the spout has a virgin function, and the fragile line once cut can be easily and clearly recognized from the outside, and also has a tamper-proof function. The cutting strength of the weak lines on both the left and right sides of the unsealing piece depends on how the weak lines are formed.
It can be set according to the required strength.

して、液漏れを起こすが極めて少ない。Further, the tamper-evident prevention stopper of the present invention is provided with an inner ring for pressing the tip of the peripheral wall of the spout portion against the inner surface of the top plate of the lid portion, and an outer ring or a contact ring. It has a leak-proof structure.
Therefore, even if the resealed container falls over after opening,
Compared to a spout in which a thin tension wire ring is torn and opened by a conventional tension ring having only a one-step liquid leakage prevention structure, liquid leakage is extremely small.
