Description

  The present invention relates to a plug. More specifically, the present invention relates to a spigot comprising a spout attached to a container and a cap connected to a lower portion of the cap body and provided with an opening history indicating band.

  Nowadays, in order to guarantee the quality of the container contents and prevent mischief, a stopper equipped with an opening history indicating band (also called a tamper-evidence band) that clearly indicates the opening history is widely used. And when this kind of plug is opened, the connection between the cap body and the opening history clarification band is cut off, thereby clearly indicating the fact that the plug is opened.

  Such a plug includes, for example, a spout fixed to the container and a cap screwed into the spout, and the cap is connected to the lower portion of the cap body via a breakable bridge portion (weakening portion). It consists of an opening history explicit band.

  When the cap body is turned in the opening direction, the bridge connecting the opening history explicit band and the cap body is broken, the opening history explicit band is disconnected, and the opening history explicit band is disconnected. We can recognize the fact that was opened.

  For example, a cap having an opening history indicating band connected by one or more bridge portions at a lower portion and a closure (corresponding to a spout) to which the cap is screwed, and a tapered portion is provided on an outer peripheral wall of the closure Further, there is a tamper-proof closure structure in which one or more concave portions into which the blade-like member provided on the inner peripheral surface of the opening history explicit band is inserted are provided in the tapered portion.

  In this closure structure, when opened, the bridge part that connects the cap body and the opening history clarification band (tamper-evidence band) is cut, leaving an opened mark, preventing tampering, and further opening the separated opening The history explicit band does not fall even if the container is turned upside down (Patent Document 1).

  Further, the lower part is composed of a cap having an opening history manifesting band connected by one or more bridge parts, and a closure main body to which the cap is screwed, and the opening history manifesting band has a free end at its distal end. The closure main body engages with the ratchet and the blade-like member that engages with the blade-like member to prevent the opening history manifesting band from rotating in the opening direction. There is a tamper-proof closure structure provided with a convex portion that prevents the upward movement of the opening history indicating band.

  Even with this closure structure, as with opening, the bridge part that connects the cap body and the opening history clarification band (tamper-evidence band) is cut, leaving an opening mark, preventing tampering, and separating. Dropping of the opened opening history explicit band is prevented (Patent Document 2).

  Known documents are shown below.

It is XX sectional drawing of FIG. In the stopper of the present invention, it is an explanatory view showing the state where the cap was plugged into the spout in a cross section.

Hereinafter, modes for carrying out the present invention will be described.
FIG. 1 is a front view of an example of the plug of the present invention. FIG. 2 is a longitudinal sectional view of an example of the spigot of the present invention. The left half is a vertical cross-sectional view of a portion with a spout-side raised portion, and the right half is a vertical cross-sectional view of a portion with a band-side protrusion. 3 is a cross-sectional view taken along line XX in FIG.

  As shown in FIG. 1, the spigot 100 of the present invention includes a cap 4 having an opening history indicating band 3 connected to a lower portion of a cap body 1 via a plurality of bridge portions 2 made of a weakened portion that can be cut, and a cap. 4 and a spout 5 which is screwed onto the screw 4.

  The cap body 1 includes a top plate portion 6, a shoulder portion 7 that is one step lower than the top plate portion 6, and a skirt portion 8 that hangs down from the peripheral edge portion of the shoulder portion 7.

  An anti-slip knurl 9 is formed on the outer surface of the skirt portion 8 so that the cap body 1 can be smoothly turned in the closing direction and the opening direction by turning by hand.

  As shown in FIG. 2, a female screw 10 is provided on the inner peripheral surface of the skirt portion 8. A male screw 12 is provided on the outer peripheral surface of the peripheral wall 11 of the spout 5. The cap body 1 of the cap 4 is screwed to the spout 5 with the female screw 10 and the male screw 12.

  The shoulder 7 of the cap body 1 is provided on the female screw 10 and the male screw 12 that are screwed together.

  And the band side protrusion 13 is provided in the inner peripheral surface of the opening history explicit band 3 under the bridge part 2 provided in the lower end of the cap main body 1. Further, on the outer peripheral surface of the peripheral wall 11 of the spout 5, a ring-shaped protrusion 14 is provided below the male screw 12 so that the band-side protrusion 13 does not go up.

  A spout-side raised portion 15 is provided on the outer peripheral surface of the spout 5 and is positioned so as to be sandwiched between the band-side protrusions 13. Therefore, when the cap body 1 is turned in the opening direction at the time of the initial opening, the rotation of the band-side protrusion 13 is prevented by the spout-side raised portion 15, and the band-side protrusion 13 moves upward by the ring-shaped protrusion 14. As a result, the opening history indicating band 3 stays at that position, and only the cap body 1 rotates and moves upward. Therefore, the bridge portion 2 is broken.

  A partition wall 16 is provided at the lower end inside the peripheral wall 11 of the spout 5 to close the lower end of the peripheral wall 11, and a thin portion 17 is provided between the partition wall 16 and the peripheral wall 11. A pull ring 18 is connected to one corner of the partition wall 16 near the thin portion 17. The pull ring 18 includes a ring portion 18 a for pulling with a finger and a column portion 18 b for connecting the ring portion 18 a and the partition wall 16.

  When the ring portion 18a is pulled with a finger, the partition wall 16 is pulled through the support column portion 18b, the thin portion 17 is broken, the partition wall 16 is removed, and the spout 5 is opened.

  At the lower end of the spout 5, a flange-like connecting portion 19 that extends outward is provided, and the connecting portion 19 is attached to the liquid paper container by being sealed. Further, a spout groove 20 that is recessed concentrically with the peripheral wall 11 is provided on the lower surface of the peripheral wall 11 of the spout 5.

  The spout groove 20 is provided with a plurality of spout groove partitioning portions 21 at equal intervals so as to partition the spout groove 20 in alignment with the lower surface of the connection portion 19 and the surface position. The spout groove 20 absorbs vibration when the stopper 100 is attached to the liquid paper container with an ultrasonic seal, and prevents cracks due to vibration from occurring in the thin portion 17.

Below the bridge portion 2 provided at the lower end of the cap body 1, a band-side protrusion 13 is provided on the inner peripheral surface of the opening history indicating band 3 as shown in FIG. 3. Further, a spout side raised portion 15 is provided on the outer peripheral surface of the spout 5, and the spout side raised portion 15 is disposed so as to be sandwiched between the band side protrusions 13.

The band-side protrusion 13 and the spout-side raised portion 15 are inclined at both circumferential ends. For this reason, when the cap 4 and the spout are assembled by being plugged, even if the circumferential alignment of the band-side protrusion 13 and the spout-side raised portion 15 is slightly shifted and overlapped, the circumferential position is shifted so as to be engaged by the inclination. Is fixed.

  Further, when the cap body 1 is turned to open the cap for the first time, the band-side protrusion 13 is prevented from rotating at the spout-side raised portion 15, the opening history indicating band 3 stays at that position, and only the cap body 1 rotates. Then move up. Therefore, the bridge | bridging part 2 is fractured | ruptured and the virgin property is ensured by this.

  FIG. 4 is an explanatory view showing, in section, a state in which the cap is plugged into the spout in the plug of the present invention.

  The cap 4 and the spout 5 are formed separately and assembled as a plug 100 by being assembled by a stopper. Molding is performed by injection molding, and a thermoplastic resin such as polyethylene or polypropylene is used.

  In order to assemble the cap 4 and the spout 5 with a stopper, first, the spout 5 is set on the cradle 22. At this time, the convex portion at the center of the cradle 22 is set in accordance with the lower recess formed by the peripheral wall 11 and the partition wall 16 of the spout 5 and the circumferential direction is set in accordance with the direction of the pull ring 18.

  Further, the spout groove 20 and the spout groove partitioning portion 21 provided so as to partition the spout groove 20 are aligned with the convex portion provided on the pedestal 22, thereby performing circumferential alignment.

  Then, the connection part 19 of the spout 5 is pressed against the receiving base 22 by the clamp 23. As a result, the spout 5 is fixed. The fixed male screw 12 of the spout 5 is covered with the circumferential position of the female screw 10 of the cap 4 approximately matching. Then, the presser jig 24 is used to push in from above. At this time, the presser jig 24 acts to push the shoulder 7 of the cap 4 downward.

In this way, since the shoulder portion 7 is located on the cylindrical peripheral wall 11 of the spout 5, the force is efficiently transmitted to the peripheral wall 11 and the skirt portion 8 below the shoulder portion 7, and the peripheral wall of the spout 5 11 extends beyond the male screw 12 provided on the skirt portion 8 of the cap 4, and the ring-shaped protrusion 14 provided on the spout 5 is replaced with the band-side protrusion provided on the cap 4. 13, the cap 4 and the spout 5 are assembled as shown in FIG.

  When assembled, even if the circumferential alignment of the band-side protrusion 13 and the spout-side raised portion 15 is somewhat shifted and overlapped, as shown in FIG. Thus, the circumferential position is corrected.

  Further, the angle between the upper surface of the male screw 12 provided on the outer peripheral surface of the peripheral wall 11 of the spout 5 and the horizontal surface, and the angle between the lower surface of the female screw 10 provided on the inner peripheral surface of the skirt portion 8 of the cap 4 and the horizontal surface. However, since each is 45 ° or more, preferably 60 ° or more, the male screw 12 of the spout 5 can be capped without using a special soft resin for the thermoplastic resin forming the cap 4 or the spout 5. The four female screws 10 can easily get over and can be easily fitted and assembled with a stopper.
