Description

  The present invention relates to a mouthpiece with a tamper-evident function that protrudes from the inside of a liquid paper container that stores liquid contents of food and non-food.

Conventionally, a tamper-evident plug has been used as a plug that can be recognized as being tampered with in order to prevent unauthorized opening of the liquid paper container that stores liquid contents in the distribution process or in stores. It had been. This tamper-evident plug has a spout and a cap that is screwed onto the spout. The cap is tamper-evident through a plurality of brittle bridges below the cap body. A band (tamper evidence band) was connected. Then, when the cap body is rotated in the screwing direction in order to open the container, the cap body and the tamper evidence band are connected by the action of the locking flap provided on the inner peripheral surface of the tamper evidence band. A plurality of fragile bridges are cut, and the tamper evidence band is separated from the cap body, and the tamper evidence band is separated from the cap body to recognize that the tamper evidence band has been tampered with in advance. It was. When the cap body is unscrewed from the spout, the upper surface of the end of the tamper evidence band in the screwing direction is connected to the lower surface of the cap body by a single brittle bridge that does not break during screwing rotation. It was removed from the spout (see, for example, Patent Document 1).

  However, the above-described conventional tamper-evident plug has been tampered with once and the cap (cap body and tamper evidence band) is screwed on the spout and left unattended at first glance. I didn't understand that.

  The present invention solves the problems of the above-described conventional conventional tamper-evidence-equipped mouth plugs, and once tampered with, the cap (cap body and tamper-evident band) is screwed onto the spout. Thus, even if it is resealed, it is possible to provide a tamper-evidence-equipped mouth plug that can clearly recognize that it has been tampered with at first glance.

  That is, according to the first aspect of the present invention, a cap with a tamper-evident band is screwed onto the spout tube of the spout, and a plurality of temporary fixing projections are provided circumferentially above the outer peripheral surface of the annular pedestal portion of the spout. A plurality of locking flaps provided in the circumferential direction of the inner circumferential surface of the tamper-evidence band and an outer circumference of the spout cylinder of the spout when the cap body of the cap is rotated in the screwing rotation direction. A plurality of brittle bridges connecting the cap body and the tamper-evidence band are cut by an engaging action with a locking ring provided below the male screw on the surface, and the tamper-evident band is screwed and rotated. The tamper-evidence is provided in a mouthpiece in which an upper surface of a direction end portion is connected to the lower surface of the peripheral wall of the cap body by a fragile bridge stronger than the plurality of fragile bridges. Among the plurality of locking flaps provided in the circumferential direction of the inner peripheral surface of the band, the locking flap on the end side in the screwing rotation direction is a locking flap having a wider fitting than the other locking flaps, and A tamper-evidence-equipped mouth plug, wherein a gap of at least 0.3 mm is provided between the lower surface of the tamper-evidence band and the upper surface of the annular pedestal portion of the spout.

  According to a second aspect of the present invention, a cap with a tamper-evidence band is screwed onto a spout tube of a spout, and a plurality of temporary fixing projections are arranged at equal intervals in the circumferential direction above the outer peripheral surface of the tamper-evidence band. When the cap body of the cap is rotated in the screwing rotation direction, a plurality of locking flaps provided in the circumferential direction of the inner circumferential surface of the tamper-evidence band and the spout cylinder outer circumferential surface of the spout A plurality of brittle bridges connecting the cap body and the tamper-evidence band are cut by an engaging action with a locking ring provided below the male screw of the tamper-evident band, and the tamper-evidence band is screwed in the rotation direction. The tamper-evidence is provided in a mouthpiece in which an upper surface of the end portion is connected to the lower surface of the peripheral wall of the cap body by a weakened bridge stronger than the plurality of weakened bridges. Among the plurality of locking flaps provided in the circumferential direction of the inner peripheral surface of the belt, the locking flap on the end side in the screwing rotation direction is a locking flap having a wider fitting than the other locking flaps, and A tamper-evidence-equipped mouth plug, wherein a gap of at least 0.3 mm is provided between the lower surface of the tamper-evidence band and the upper surface of the liquid paper container.

  The spigot with a tamper-evident function (10) shown in FIG. 1 provided with a temporary fixing projection on the annular pedestal of the spout of the present invention has a plurality of locking flaps provided in the circumferential direction of the inner peripheral surface of the tamper-evident band. Among these, as shown in FIG. 2 (a), the engagement flap (124) having a wider fitting with the engagement flap on the end side in the screwing rotation direction (X) is wider than the other engagement flap (125). Therefore, the cap body is rotated in the screwing rotation direction (Y), and a plurality of brittle bridges connecting the cap body and the tamper evidence band are cut, and the end of the tamper evidence band in the screwing rotation direction is cut. When the tamper evidence band is separated from the cap body by connecting the upper surface of the cap portion and the lower surface of the peripheral wall of the cap body with a strong brittle bridge, as shown in FIG. As shown in FIG. 1, the gap between the lower surface of the tamper evident band (120) and the upper surface of the annular pedestal (210) of the spout (200) is large. Since there is a gap (h) of at least 0.3mm between them, even if the tamper-evident cap (cap body and tamper evident band) is screwed into the spout and resealed, at first glance , You can clearly recognize that it has been tampered with. Note that the gap is desirably 0.5 mm or more, and if the gap is longer, it is better.

  Further, the tamper-evidence-equipped mouth plug (10) shown in FIG. 3 in which the tamper-evidence band according to the present invention is provided with a temporary fixing protrusion is provided with a plurality of engagements provided in the circumferential direction of the inner peripheral surface of the tamper-evidence band. Among the flaps, as shown in FIG. 2 (a), the locking flaps on the end side in the screwing rotation direction (X) are wider than the other locking flaps (125). ), The cap body is rotated in the screwing rotation direction (Y), and a plurality of brittle bridges connecting the cap body and the tamper evidence band are cut, so that the tamper evidence band is screwed in the rotation direction. When the tamper evidence band is separated from the cap body by connecting the upper surface of the end portion and the lower surface of the peripheral wall of the cap body with a strong brittle bridge, as shown in FIG. The opening of the dent band (120) to the outside from the cap body (110) is large, and, as shown in FIG. 3, between the lower surface of the tamper evident band (120) and the upper surface of the liquid paper container (20). Since there is a gap (r) of at least 0.3 mm, even if the cap (the cap body and the tamper evidence band) that has been tampered with is screwed into the spout and resealed, You can clearly recognize that it has been opened.
