In recent years, the technology of information display using an IC tag has come to be used to display product information such as date of manufacture and manufacturer / seller. An IC tag is also referred to as RFID (Radio Frequency Identification), and is formed in the shape of a tag (tag) by embedding an IC chip storing predetermined information in a dielectric material such as resin or glass together with a wireless antenna. It is a small communication terminal. Such an IC tag reads product information stored in the IC chip by wireless communication. For example, several hundreds of bytes of data can be recorded in the memory of the IC chip, and many pieces of product information can be stored. It is also proposed to use such an IC tag for the opening history explicitly because it has the advantage of being recordable.

A container lid comprising such an IC tag has also been proposed. For example, Patent Document 1 listed below includes an inner lid that can seal the container and an outer lid that covers the inner lid from the outside, and a top plate portion of the outer lid. In the case of a container lid comprising an upper lid having a protrusion extending downward from the inner surface of the lid, an IC tag is provided such that a tip end of the protrusion formed on the upper lid covers an opening formed on a top plate portion of the outer lid. There has been proposed a container lid which is fixed at the inner surface of the top plate portion and the tip of the projection, and the antenna is broken in the vicinity of the IC chip by removing the upper lid from the cap body.
Further, in Patent Document 2 below, a cap provided with an IC tag is proposed which is provided on an upper lid and provided with an IC tag formed on the top plate of the cap main body, and cuts the circuit of the IC tag by a cutter which moves with the opening operation of the upper lid.

As the flexible connecting portion 40 is further pressed to overlap the cylindrical side wall 50 from the lower end of the skirt portion 3 of the cap body 10, the upper end and the lower end are switched from the state of FIG. It moves as shown in FIG. 8 (C) and (D) and finally located between the cap body skirt 3 and the cylindrical side wall (FIG. 7 (B) and FIG. 8 (E)). In this state, as shown in FIG. 7 (D), the lower end of the skirt portion 3 and the lower end of the engagement protrusion 51 substantially coincide with each other, and the engagement protrusion 51 is outside by the skirt portion 3 and the flexible connecting portion 40. After being tightened, it moves inward and engages with the engagement projection 62 of the container opening. As a result, the cap with the IC tag does not come off the container opening.
In this embodiment, on the outer periphery on the inner surface side of the top plate portion 2 of the cap main body 10, members 9, 9 which are in contact with the container opening top surface 61 at the time of tapping are formed. This prevents the impact at the time of taping from being directly applied to the IC tag, thereby preventing the IC tag from being damaged.

Next, the lid opening operation of the IC tag attached cap according to the present invention shown in FIGS. 4 to 8 applied to the container opening will be described according to FIG.
FIG. 9A is a view showing a state in which the IC tag-attached cap 1 is applied to the container opening 60, and the upper lid 20 is lifted about the hinge 11 by pulling up the knob 24 of the upper lid 20. . As shown in FIG. 6, in the closed state, the first locking member 4 formed on the top plate portion of the cap body and the second locking member 23 formed on the upper lid 20 are nonreleasably locked. Therefore, as the upper lid 20 is raised, as shown in FIG. 4, the score 5 formed on the cap body top plate 2 is broken, and the top plate 2 a divided by the score 5 and the inside of the top plate 2 a The IC tag (not shown) embedded in is separated from the top plate 2b outside the area divided by the score 5 (FIG. 9 (B)). When the upper lid 20 is further pulled up, the score 8 formed on the skirt portion 3 extending downward from both sides of the hinge 11 is broken so as to be continuous with the score 5, and the skirt portion 3b divided by the score 8 is a skirt It separates from the part 3a (FIG. 9 (C)). When the upper lid 20 is further pulled up, the flexible connection portion 40 is separated from the outer surface of the cylindrical side wall 50 (FIG. 9 (D)). In this state, the projection 51 for engagement of the cylindrical side wall 50 at the part where the flexible connection part 40 is released is released from the tail tightening from the outside, and is in the state shown in FIG. The engagement of the portion 60 with the engagement projection 62 is released, and the cap 1 can be easily removed from the container opening 60.

For example, the first locking member and the second locking member formed on the upper surface of the cap body top plate portion and the inner surface of the upper lid lock the upper lid in a closed state and can not release the locking after the locking. If it is, various forms can be adopted.
In the specific example shown in the figure, the cap main body and the tubular side wall are connected by the plurality of strip-like flexible connecting members, but the example shown in the figure is preferable in terms of the ease of buckling. However, it may be an annular flexible connecting member. Furthermore, the plurality of members formed on the inner periphery of the cap body top plate portion and in contact with the container top surface may be annular members, which may not be necessary depending on the device used for taping, and also cylindrical The fixture formed at the upper end of the side wall may not necessarily be provided as long as the lower end of the cylindrical side wall can be fixed.
Furthermore, although the score formed in the top plate part was formed from both the inner and outer surface of the top plate part, it can also be formed only from the upper surface.

Furthermore, in the specific example shown in the figure, the weakened portion corresponding to the score is formed also in the IC tag, but it is not necessarily formed if the base is easily cut by the material and thickness of the base of the IC tag. do not have to.
In the specific example shown in the figure, the holes formed in the IC tag are also formed inside and outside the area divided by the score, but may be formed only outside the area divided by the score, or the IC tag In the case where the weakened portion corresponding to the score is formed, or when the material of the base material of the IC tag is excellent in the adhesiveness with the material of the cap, etc., it may not necessarily be formed.

The cap with an IC tag of the present invention can be suitably molded by injection molding, and by embedding the IC tag in the top plate portion by insert molding, the IC tag can not be visually recognized from the outside, and there is also a possibility of breakage. Caps with no IC tags can be easily molded.
As resin which comprises a cap main body, polyethylene, a polypropylene, etc. which were conventionally used for the hinge cap can be used.
Although the IC tag attached cap of the present invention has been described in the preferred embodiment in which the IC tag is embedded in the top plate using the attached drawings, the IC tag is firmly attached to the outer surface of the top plate and formed on the top plate As long as the antenna of the IC tag can be broken by breaking the score, the same effect can be obtained even if the IC tag is attached to the outer surface of the top plate. For example, the IC tag forms a score similar to the score formed on the top plate, and the IC tag is also broken simultaneously with the breakage of the score on the top plate, which makes it possible to reliably break the antenna.

Since the IC tag-attached cap of the present invention surely destroys the IC tag at the same time as opening, the refilling and mischief of the contents can be surely prevented, and in particular, the inexpensive contents are refilled and sold for the regular contents. It can be suitably used for caps of higher alcohols in which crime is occurring.
The cap with an IC tag of the present invention can also be applied directly to the container opening, or can be applied as an overcap over the cap applied to the container opening.
