  • the front surface 160 of the HIC 100 includes a plurality of parallel lines that provide an area to input personal or other information.
  • the back surface 180 of the HIC 100 includes the information section 240 including a plurality of parallel lines that provide an area to input personal or other information.
  • the information section 240 allows a user or provider to include contact information so that the product may be returned to the user or provider if it becomes lost, to provide information about a product in the environment the HIC 100 is monitoring, and/or information about the HIC 100, for example, a guide to reading or replacing the HIC 100.
  • the front side 160 of the HIC 100 includes six indicators 120, the label 140 adjacent the indicators 120, the UHF tag 210, the EAS tag 220, and the information section 240. Accordingly, the HIC 100 provides humidity indication, security/inventory tracking, and presents information about the owner, the product and/or the environment the HIC 100 is monitoring, and/or information about the HIC 100.
  • the front side 160 of the HIC 100 includes six indicators 120 and the label 140 adjacent the indicators 120, and the back side 180 of the HIC 100 includes the UHF tag 210 and the information section 240. Accordingly, the HIC 100 provides humidity indication, security/inventory tracking, and presents information about the owner, the product and/or the environment the HIC 100 is monitoring, and/or information about the HIC 100.
  • the front side 160 of the HIC 100 includes six indicators 120, the label 140 adjacent the indicators 120, the UHF tag 210 and the EAS tag 220. Accordingly, the HIC 100 provides humidity indication and security/inventory tracking.
  • the HIC 100 may be used in a variety of ways. For example, as illustrated in FIG. 1 1 , the HIC 10 may be inserted into the container 300 having a product 320 contained therein. The HIC 100 thus monitors the humidity level inside the container 300 and provides the above-described security and inventory tracking features. Further, in some applications (such as embodiments where the product 320 is tobacco), it may be desirable to continually monitor the humidity level of the environment surrounding the product 320 throughout the life of the product 320. As such, the user will not typically be motivated to discard the HIC 100 until the product 320 is depleted.
  • the security tracking device e.g., the RFID 200
  • the HIC 100 is made of a fiber composite
  • the HIC 100 may be adhered or affixed to a humidity controller, e.g., the humectant system 1.
  • the HIC 100 may be adhered to a front surface or a back surface of the humectant bag 10.
  • the HIC 100 may be affixed or adhered to the humectant bag 10 by an adhesive 18.
  • the adhesive 18 may be any suitable adhesive, including glue, hot melt adhesive (or hot glue), single-sided tape, double-side tape, and/or adhesive backing.
  • the HIC 1 10 is adhered to the humectant bag 10 by hot melt adhesive.
  • the hot melt adhesive is well-suited for this application because it is able to withstand possible changes in temperature and relative humidity without significantly losing efficacy. Further, the hot melt adhesive provides a secure connection between the humectant bag 10 and the HIC 100.
  • the adhesive 18 may be applied to back edges and corners of the HIC 100 to effectively form a seal between the HIC 100 and the humectant bag 10, thereby preventing any substances from entering a space between the HIC 100 and the humectant bag 10 after they are adhered to each other.
  • the adhesive 18 is a hot melt adhesive having a .45 inch diameter applied by a 50W glue gun.
  • the adhesive 18 may serve as a barrier between the HIC 100 and the humectant bag 10 (and the humectant material 14 contained therein). Without the use of a suitable adhesive 18, the HIC 100 may provide a reading that more closely resembles the humidity level inside of the humectant bag 10 instead of the humidity level of the environment outside of and surrounding the humectant bag 10. As such, the adhesive 18 may also serve as a barrier between the HIC 100 and the humectant bag 10 to reduce or minimize the likelihood of an inaccurate reading from the HIC 100.
  • the humidity controller is the humectant system 1
  • the humidity controller is a desiccant, an oxygen scavenger, and/or a humectant. It will be appreciated that the same considerations regarding use of an adhesive for affixing the HIC 100 to a humidity controller including the humectant system 1 may be the same or similar as considerations related to affixing the HIC 100 to a humidity controller that is a desiccant, an oxygen scavenger, and/or a humectant.
  • a suitable adhesive 18 may be used to reduce the likelihood of inaccurate readings based on proximity of the HIC 100 and the desiccant, oxygen scavenger, and/or humectant, and the adhesive 18 may be placed to reduce the likelihood of product becoming entrapped between the HIC 100 and the desiccant, oxygen scavenger, and/or humectant.
