Title: Container cap having identification function and its manufacturing method

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to a container cap having identification function and its manufacturing method. A method of manufacturing such a container cap is to have a label placed in a male mold of a cap-shaping mold in advance to let the main body of the label contacting with the inner side of the top wall of a cap and the extensions of the label contacting with the circumferential surface and extended to the positioning circumference of the cap when the cap body is being shaped. When the container cap is turned open, an abuttal portion between the circumferential surface and the positioning circumference of the cap is to be torn off, letting partial extension antennas broken off to block off or send forth radio frequency identification signals, thus producing efficacies of anti-counterfeiting and anti-theft. 
     2. Description of the Prior Art 
     A conventional radio frequency identification bottle cap, as disclosed in a Taiwan patent No. M355918, titled “ANTI-COUNTERFEITING BOTTLE CAP”, includes a main body, a neck and at least one joint portion. A gap is formed between the main body and the neck and the joint portion traverses the gap and connected with both the main body and the neck. The radio frequency system label is provided on the cap, with a first antenna and a chip disposed in the main body of the cap, a second antenna positioned in the neck of the cap and a third antenna traversing the gap and bridging both the first antenna and the second antenna. 
     When the anti-counterfeiting bottle cap is turned around, the neck will not be rotated together with the main body because a stop projection resists against at least one stop block of the bottle body and meanwhile, the joint portion will be broken and separated from the main body or from the neck because the joint portion traverses the gap and connected with the main body and the neck. In addition, since the first antenna and the chip are secured with the main body of the cap, the second antenna is fixed with the neck and the third antenna traverses the gap and is bridged with both the first antenna and the second antenna, therefore, when the anti-counterfeiting bottle cap is turned around, the third antenna will be broken and separated from the first and the second antenna and lose electrical function to disable a reader to read all the data stored by the radio frequency system label, thus able to confirm whether or not the anti-counterfeiting bottle cap was opened. 
     Obviously, the conventional anti-counterfeiting bottle cap makes use of the third antenna of the radio frequency system label to electrically connect with the second antenna and the third antenna and is based on the situation whether the data stored by the radio frequency system label can be read to confirm whether the anti-counterfeiting bottle cap was opened. However, bottled products for sale, such as expensive drugs, chemical materials or raw materials, need to be worried about whether they were opened and also need to be prevented from being stolen by thieves. To steal such bottled products, a thief may destroy the induction function of radio frequency identification system by means of destroying tools or in a way of heating, for example, apparatuses that can produce high energy, such as micro-wave ovens that are to be tried out for sale. Thus, the radio frequency identification system of the bottled products will lose efficacy of anti-theft and will result in losses to shop owners. Moreover, when the conventional anti-counterfeiting bottle cap is turned open, a condition that the third antenna cannot be torn off and separated from the second antenna will always occur and as a result, the radio frequency identification signal cannot timely be blocked off, thus impossible to produce a marked effect of anti-counterfeiting. 
     SUMMARY OF THE INVENTION 
     The objective of this invention is to offer a container cap having identification function and its manufacturing method, able to produce marked effects of anti-counterfeiting and anti-theft. 
     The container cap having identification function in the present invention includes a radio frequency identification label having a protective layer stuck thereon. The radio frequency identification label is made by having a radio frequency identification system provided on a substratum and having one side of the radio frequency identification system disposed with a gluey layer to be stuck with the protective layer. 
     The container cap having identification function in the present invention has the label provided with a main body for receiving the radio frequency identification system and antennas together with extension antennas. The main body of the label is formed with a plurality of extensions for setting the extension antennas thereon. 
     A method for manufacturing a container cap having identification function is to have the label placed in a male mold of a cap-shaping mold beforehand. When the cap is being shaped in the mold, the main body of the label will be contacting with the inner side of the top wall of the cap and the extension portions of the label will be contacting with the circumferential surface and extended to the positioning circumference of the cap. Thus, when the container cap is turned open, an abuttal portion of the circumferential surface and the positioning circumference of the cap will be torn off, letting partial extension antennas broken off to disconnect or send forth radio frequency signals for producing efficacies of anti-counterfeiting and anti-theft.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A first preferred embodiment of a container cap having identification function and its manufacturing method in the present invention, as shown in FIGS. 
       1 - 4 , includes a label  1  provided with a radio frequency identification label  10 . A first step of manufacturing the radio frequency identification label  10  is to have antennas  120  of a radio frequency identification system  12  printed or engraved on a substratum plate  11 , as shown in  FIGS. 1 and 2 , and then have the identification chips  121  of the radio frequency identification system  12  fixed on the substratum plate  11  and connected with the antennas via surface-mount technique (SMT). A second step is to apply adhesive material to one side of the radio frequency identification system  12  on the substratum plate  11  to make up a gluey layer  13 , as shown in  FIGS. 3 and 4 . A third step is to have a separable layer  14  stuck on the gluey layer  13  of both the substratum plate  11  and the radio frequency identification system  12 , as shown in  FIGS. 5 and 6 . A fourth step is to have all the radio frequency identification labels  10  respectively cut into shape for facilitating each radio frequency identification label  10  to be removed from the separable layer  14 , as shown in  FIGS. 7 and 8 . A fifth step is to remove the radio frequency identification labels  10  from the separable layer  14  and have each radio frequency identification label  10  stuck thereon with a protective layer  15 , which is the same as or partially different from the radio frequency identification label  10  in external looks, as shown in  FIGS. 9-11 . Thus, the label  1  is composed of the radio frequency identification label  10  and the protective layer  15  stuck together. 
     Referring to  FIGS. 9-11 , the label  1  is provided with a main body  1 A for receiving partial substratum plate  11  of the radio frequency identification label  10  and as previously described; the substratum plate  11  is printed thereon with the antennas  120  and the identification chips  121  of the radio frequency identification system  12 . The main body  1 A is formed with a plurality of extensions  1 B for receiving extension antennas  120 A of the antennas  120 . The extension antennas  120 A can be one set, as shown in  FIG. 14 , or two sets, as shown in  FIG. 10  or three sets, as shown in  FIG. 13  or more than three sets, depending on practical needs. Referring to  FIG. 12 , plural identification chips  121 ,  121 A of different purposes of anti-counterfeiting or anti-theft can be provided in this invention for producing different efficacies. For instance, when the extension antennas are broken off, the chips will produce or block off signals to produce different objectives. 
     The cap  2 , as shown in  FIG. 16 , is provided with a top wall  20  having its circumferential edge extended downward and formed with a circumferential surface  21  having a positioning circumference  22  disposed at an under side. A plurality of insert holes  23  are bored between the positioning circumference  22  and the circumferential surface  21 , as shown in  FIGS. 17 and 18 , and an abuttal portion  24  is formed between the adjacent insert holes  23 . 
     Referring to  FIG. 15 , through in-mold shaping technique, the label  1  is placed in the male mold  30  of a cap shaping mold  3  beforehand, letting the main body  1 A of the label  1  located at a front end  300  of the male mold  30  and the extensions  1 B of the label  1  closely touch the inner side  301  of the male mold  30 . A shaping slot way  32  for shaping the cap  2  will be formed after the female mold  31  and the male mold  30  of the cap-shaping mold  3  are combined together. 
     When the cap  2  is shaped in the shaping slot way  32  through plastic injection molding or vacuum forming or blow forming, the main body  1 A of the label  1  will be combined with the inner side of the top wall  20  of the cap  2 , as shown in  FIG. 16 , and the extensions  1 B of the label  1  will be contacting with the circumferential surface  21  and extended to the positioning circumference  22  of the cap  2 . 
     When the cap  2  of a container  2 A is turned open, as shown in  FIGS. 17 and 18 , the abuttal portion  24  of the circumferential surface  21  and the positioning circumference  22  of the cap  2  will be torn off, letting parts of the extension antennas  120 A broken off for blocking or giving out radio frequency identification signals and thus able to produce efficacies of anti-counterfeiting and anti-theft. 
     While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
