Description

  The present invention relates to a cap for covering a spout, comprising a pilfer proof band for indicating that the cap has been initially opened.

  Conventionally, a carton having a cap attached to a spout has been widely used. With this kind of cap, even if the cap is removed once and the spout main body is opened, if the cap is tightened into the nozzle portion of the spout main body as before, the appearance will be the same as before opening the cap. For this reason, for example, even if someone removes a cap by tampering with a carton spout at a store and performs tampering such as opening it, it is not possible to tell if the cap is restored and whether or not tampering has occurred. There was a problem that it could not be recognized.

  Therefore, in order to easily identify the presence or absence of cap opening, the cap body is attached to the spout body by screw fitting, and the lower end of the cap body is connected via a connecting portion that can be broken when the cap body is opened. A cap including a pilfer proof band that is connected in such a manner that cannot be pulled out from the spout body is disclosed (for example, Patent Document 1). With this configuration, when the cap is opened, the connecting portion is broken and the pilfer proof band remains below the spout, so that the presence or absence of the opening can be distinguished.

The spout 4 is a flange portion 4F for attaching the spout 4 to the carton K, a cylindrical nozzle portion 4N, a shielding portion 4S for closing the nozzle portion 4N, and a part of the shielding portion 4S. An opening groove 4M provided to be able to be provided, and a pull ring 4P connected to a region surrounded by the opening groove 4M via a support column 4T. And the thread 4Y for screw-fitting the cap 1 is formed in the outer peripheral surface of the nozzle part 4N.

A slit S is formed between the cap body 2 and the pill fur proof band 3 over the entire circumference, and the cap 1 is formed on the cap body 2 above the slit S and the pill fur proof band 3 on the lower side. , Is divided into.
Below the screw thread 4N of the spout 4 is formed a protrusion 4B for separating the cap body and the pill fur proof band when the cap 1 is initially opened. The cap body and the pilfer proof band are separated by the tip of the proof band being caught by the protrusion 4B.

  As shown in FIG. 3, the child pilfer proof band 5 and the cap body 2 are connected via a plurality of connecting portions. And this connection part consists of the connection part 10 which fractures | ruptures simultaneously with initial stage opening, and the connection part 11 which does not fracture | rupture at the time of initial stage opening. At least one end portion of the child pill fur proof band 5 is connected to the cap body 2 via the connecting portion 11. Further, a plurality of connection portions 10 to be cut at the time of initial opening are formed from the vicinity of the other end of the child pilfer proof band 5.

The pilfer proof band 3 is formed with a plurality of blade members on the inner surface, and the blade members include a first blade 8, a second blade 9, and a third blade 12. These blade members (8, 9, 12) are inclined inward upward from the vicinity of the lower end of the pilfer proof band 3, and the tips of the blade members are in contact with the side wall of the spout.
The tip portion of the third blade 12 (cutting member) of the blade member is in contact with a protrusion 4B formed below the thread 4N of the spout 4 and the cap body 2 is moved upward when the cap 1 is initially opened. Even if moved, the tip of the third blade 12 of the pilfer proof band 3 is hooked on the protrusion 4B of the spout 4 so that the pilfer proof band 3 cannot move upward and only the connecting portion 10 is cut. And when the connection part 10 is cut | disconnected, the child pill fur proof band 5 will open outside on the connection part 11 by the repulsive force which the 1st blade | wing 8 (repulsion member) presses the side wall 4H of the spout 4, The initial opening of the cap 1 is completed.

  The cap 1 may be manufactured into a final shape by molding, that is, the cap main body 2 and the pilfer proof band 3 may be connected to each other via a connecting portion. And the pilfer proof band 3 are preferably formed so as to be connected over the entire circumference, and the boundary between the cap body 2 and the pilfer proof band 3 is separated by slitting except for the connecting portion. . For example, the cap main body 2 and the pilfer proof band 3 are molded in an integrated structure in which the pilfer proof band 3 having a plurality of blade members is connected to the inner surface, and the cap main body 2 of the cap 1 and the pilfer proof band 3 The boundary can be slit with a suitable cutter blade. In this way, the cap body 2 and the pilfer proof band 3 can be separated by the slit S having a very small thickness, and the slit S is inconspicuous. The advantage that it can be obtained. Further, at the time of slitting work for cutting between the pilfer proof band 3 and the cap main body 2, the distal end portions of the closing member 9 and the cutting member 12 formed on the inner surface of the pilfer proof band 3 are the spout 4. By abutting on the side wall 4H, the slit operation can be performed stably without causing the lower end of the cap 1 to bend inward during the slit operation.

Hereinafter, the configuration and operation of the cap with a pilfer proof band of the present invention will be described. FIG. 4 is a cross-sectional view of the pilfer proof band 3 including two child pilfer proof bands 5 on the left and right. A plurality of blade members are formed on the inner surface of the pill fur proof band 3 on the inner surface of the child pill fur proof band 5. This blade member pushes the second blade 9 (blocking member) for closing the gap formed between the pilfer proof band 3 and the spout 4 and the side wall 4H of the spout 4 when initially opened to pilfer proof. A first blade 8 (repulsion member) having a repulsive force for separating the band 3 from the spout 4 by a certain distance, and a third blade 12 (for separating the cap body 2 and the pilfer-proof band 3 at the time of initial opening) Cutting member).
The first blade 8 and the second blade 9 are provided so as to be inclined inward from the vicinity of the lower end of the inner surface of the pilfer proof band 3 toward the upper side (or from the upper side to the lower side). The inner surface of the proof band 3 is provided so as to be inclined inward upward from the vicinity of the lower end of the inner surface thereof.

  Before the initial opening of the cap 1, the first blade 8 and the second blade 9 of the child pilfer proof band 5 are connected to the cap body 2 by the connecting portion between the first blade 8 and the second blade 9, Since it is in close contact with the side wall 4H of the spout 4, it is smaller than the inward inclination angle after the initial opening. When the cap 1 is initially opened, the connecting portion 10 between the child pill fur proof band 5 and the cap body is broken. At this time, one end of one child pill fur proof band 5 is connected to the connecting portion. 11 is connected to the cap body 2 via 11, the child pilfer proof band 5 opens to the outside with respect to the spout 4 around the connecting portion 11. That is, when the cap 1 is initially opened, the first blades 8 (repulsive members) of the respective child pilfer proof bands 5 give a repulsive force to open at a normal inward inclination angle to the side wall 4H of the spout 4. As a result, the child pilfer proof band 5 is in a state in which the distal end portion of the first blade 8 is opened at a distance of pressing the side wall 4H with the connecting portion 11 as an axis. Further, the repulsion member 8 is provided in the vicinity of the connecting portion 11. On the other hand, the cutting member 12 is provided in the vicinity of the connecting portion 10. With this configuration, the opening degree of the child pilfer proof band 5 by the repulsion member 8 in the vicinity of the connecting portion 11 becomes larger when the cap 1 is initially opened.

  In this way, by dividing the pill fur proof band 3 into a plurality of child pill fur proof bands 5 and combining them, when the repulsion member 9 of each child pill fur proof band 5 is initially opened, the side wall 4H of the spout 4 is formed. Since the child pilfer proof band 5 is opened by pressing, it can be easily recognized that the cap 1 has been initially opened as shown in FIG. Further, even after the initial opening, the pilfer proof band 3 and the cap body 2 are not completely separated and are connected via the connecting portion 11. Therefore, even if the cap 1 is closed again after opening the cap 1, the pilfer Since the proof band 3 pushes the side wall 4H of the spout 4 and spreads again, it can be confirmed at a glance that the proof band 3 has already been opened.

  For the material of the cap body 2 and the spout 4 having the above-described configuration, a material used for a conventional spout may be used as appropriate. For example, a low density polyethylene resin, a medium density polyethylene resin, a high density polyethylene resin, a straight chain Examples of the resin include low-density polyethylene resin, polystyrene resin, ionomer resin, polypropylene resin, acrylic resin, nylon resin, polyester resin, and polycarbonate resin. Further, the number of pilfer proof bands is not limited to two, but may be one or three (FIG. 6B) and four (FIG. 6A) as shown in FIG. Thereby, since the pilfer proof band 3 after the initial opening draws a beautiful curved shape by the combination of the plurality of child pilfer proof bands 5, it is possible to provide the cap 1 having a beautiful and pleasant image.
