This document relates generally to detectable sensors, such as Radio Frequency Identification (“RFID”) sensors and/or security tags used in Electronic Article Surveillance (“EAS”) systems to protect optical wear (e.g., eyeglasses and eyeglass frames). More particularly, this document relates to detectable sensors which do not stain items to which they are coupled.
In retail stores for optical articles, it is desirable to present a large variety of eyeglasses and eyeglass frames to prospective buyers in a manner which allows them easily to examine and compare a large number of different frames or eyeglasses. Eyeglasses and eyeglass frames are constructed with temple pieces or earpieces to engage a wearer's ears to hold the eyeglasses in place. The eyeglass temples are usually pivotally coupled to a lens support. The lens support may include spaced pads or an arch portion which fits the bridge of the nose. This construction is common to eyeglass frames, finished eyeglasses, sunglasses, reading glasses, goggles, protective eyewear and the like.
Eyeglasses and eyeglass frames may be expensive. Their value and relatively small size make these articles target for thieves. In order to prevent theft, optical retailers often display eyeglasses or frames in locked glass cases. This approach not only greatly increases the overhead, but also requires the presence of salespeople to allow a customer to try on a pair of eyeglasses. In addition, display cases present a barrier between the customer and the product.
Other attempts to overcome security problems include connecting eyeglass frames to a weight or fixture using cables or chains. Such devices allow customers to handle the eyeglasses and try them on without the assistance of personnel. The cable or chain connecting the model eyewear to the weight or fixture may be effective for preventing a thief from pocketing the eyewear, but there are shortcomings in this type of system as well. The cables or chains connected to the model eyewear can break or become tangled from customer handling. Tangled cables and chains prevent customers from fully accessing the model eyewear and make the display space look unattractive. Cables or chains attached to eyewear also interfere with the customer's ability to try on the eyewear comfortably. Sometimes cables or chains are removed by personnel to allow a customer to try on a product, which reduces the effectiveness of the security system.
The disclosure concerns implementing systems and methods for operating a security tag. The methods comprise: disposing a portion of an article (e.g., optical wear) between at least a first pad and a second pad of the security tag; applying a compressive force to the portion of the article disposed between the first and second pads; and concurrently providing by the first and second pads (A) a non-slip grip on the portion of the article and (b) prevention of article staining caused by at least one of oxidization, a chemical interaction, and outgassing.
In some scenarios, the article staining is at least partially prevented by using the first and second pads which comprise a ThermoPlastic Vulcanizates (“TPV”) material (e.g., Santoprene™). The first and second pads area adhered to a housing of the security tag via a double-sided tape or other adhesive means.
In those or other scenarios, the article staining is at least partially prevented by allowing gasses released from an outgassing material to pass through at least one channel formed between the first and second pads and be released into a surrounding environment. The channel is formed by a plurality of protrusions extending out and away from the first or second pad. At least two of the plurality of protrusions have the same shape or different shapes.
In some cases, the channel is formed by a first plurality of protrusions extending out and away from the first pad and a second plurality of protrusions extending out and away from the second pad. The first and second plurality of protrusions may comprise the same or different numbers of protrusions.

There are many security tags known in the art for eyewear. One such security tag is described in U.S. patent application Ser. No. 14/548,585 filed Nov. 20, 2014 entitled “SECURITY TAG.” This security tag is referred to herein as the '585 security tag. The '585 security tag can include a detectable sensor, such as an EAS marker and/or an RFID sensor. The '585 security tag allows customers to handle and try on eyewear without interference therefrom. The '585 security tags can be easily attached and detached from the eyewear by one or more authorized persons (e.g., store personnel).
The '585 security tag is generally configured to be attached to a side frame or temple of optical wear such that the security tag do not interfere with the wearers' vision. Parallel soft pads (usually formed of a flexible plastic material) are provided along with a securement mechanism of the security tag so as to minimize any damage to the side frame or temple of the optical wear to which a compression force is being applied by the securement mechanism. The securement mechanism is designed to apply a compression force which is effective for any frame or temple thickness.
However, it has been observed that conventional security tags (such as the '585 security tag), which use a plastic or rubber material for the soft pads, cause staining of the eyeglass stems or temples at the point where the eyeglass stems or frame contact the pads. This staining may be caused by (1) oxidization, (2) chemical interactions between the pad material and the eyewear material, and/or (3) outgassing from pad material and/or eyewear material.
It is well known in the relevant industries that most plastics and rubbers are made from petroleum (oil or natural gas), and can contain a chemical additives. These additives are usually not chemically bonded to the polymer, but are merely mixed into the plastic or rubber during its formulation. Over time, the additives leach out of the plastic or rubber material in a process known as outgassing. The outgassing from the eyewear material normally disperses. However, the plastic/rubber pad material used in the conventional security tags traps the gas released from the pad/eyewear on the surface of the eyewear, thereby causing staining of the eyewear.
Therefore, there exists a need for an improved EAS security system for optical wear and other articles that not only (1) allow customers to handle and try on the same without interference from the security tag and (2) can be easily attached and detached therefrom by one or more authorized persons (e.g., store personnel), but also (3) do not cause or contribute to the staining of the optical wear or other articles. Accordingly, the present disclosure concerns improved security tags for eyeglass frames, finished eyeglasses, sunglasses, reading glasses, goggles, protective eyewear and other types of articles having similar needs or attributes. In the optical wear scenarios, the security tags are generally configured to be attached to a side frame or temple of optical wear such that the security tags do not interfere with the wearers' vision.
Parallel soft pads are provided along with a securement mechanism of each security tag so as to minimize any damage to the side frame or temple of the optical wear to which a compression force is being applied by the securement mechanism. The securement mechanism is designed to apply a compression force which is effective for any frame or temple thickness. The pads are designed so that the eyewear is gripped in a manner that does not allow slipping of the security tag off of the eyewear. In this regard, the pads are formed of a material that has a non-slip gripping feature.
At least one of the pads may also have a plurality of features (e.g., protrusions) designed to provide traction for preventing slippage of the EAS security system off of any frame or temple. The features can be spaced apart from each other so as to create channels for facilitating the ventilation of outgasses from the pad material and/or eyewear material. Notably, the channels alone are not enough to prevent staining of the eyewear since at least a portion of the pad material directly contacts the eyewear frame to provide the requisite compression force. Therefore, the pads are additionally formed from a new material.
Notably, the novel pads of the present solution are not a slight structural change to security tags. In this regard, it should be understood that stain prevention is a significant additional feature for eyewear security tags, which is not easily or customarily achieved by those skilled in the art. Significant research and development was performed by the present inventors to obtain security tags with such a stain prevention feature to support the project at hand: security tags which do not stain eyewear being protected thereby. The stain prevention was achieved by employing a new material for the pads, namely a ThermoPlastic Vulcanizates (“TPV”) material.
TPVs are part of the ThermoPlastic Elastomer (“TPE”) family of polymers, but are closest in elastomeric properties to Ethylene Propylene Diene Monomer (“EPDM”) thermoset rubber, combining the characteristics of vulcanized rubber with the processing properties of thermoplastics. TPV is a dynamically vulcanized alloy consisting mostly of fully cured EPDM rubber particles encapsulated in a PolyPropylene (“PP”) matrix.
Stain prevention of the TPV pads is an unexpected result. In this regard, it should be understood that TPVs are typically used in automotive, industrial and demanding consumer applications for flexible engineered parts which require long term performance. Others have recognized the following benefits of using TPVs to replace thermoset rubber in these listed applications: reduce part weight and cost; increase reliability of part performance; and improve manufacturing efficiencies. However, others have not recognized the advantages or desirable features of a security tag resulting from solid or channeled TPV pads. In fact, the inventors assert that a security tag with a stain prevention feature is a surprising and unexpected result of a TPV implementation. For example, it is surprising and unexpected that staining does not occur when solid TPV pads are used in security tags to protect eyewear formed of outgassing materials.
A TPV material which is suitable for use in the present solution is produced and sold by the Exxon Mobile Corporation under the brand name Santoprene™. Santoprene™ is designed specifically for use in medical and healthcare applications, and not for consumer good protection applications. Still, the inventors considered this material during the research and development for security tag applications, and found surprising advantages associated with its use as a pad material.
Notably, in some scenarios, the security tags of the present solution further implement a one-click application method for enabling their attachment to articles. The one-click application method eliminates the human factor which during attachment may make the security tag easy to defeat due to insufficient compression force or otherwise make the security tags inoperable due to excessive compression force. The security tags also have a one-piece design, thus ensuring easy handling and less inventory management thereof. Known magnetic detachers can be used to detach the security tags from the articles.

During store hours, a customer (not shown) may desire to purchase the article 102. The customer can purchase the article 102 using a Point Of Sale (“POS”) station 104. The POS station 104 can include, but is not limited to, a traditional fixed Point Of Sale (“POS”) station (e.g., a checkout counter) or a mobile POS station. In either scenario, a retail transaction application executing on a computing device 108 of the POS station 104 facilitates the exchange of data between the article 102, security tag 132, customer, store associate (not shown) and/or Retail Transaction System (“RTS”) 118 of a corporate facility 152. For example, after the retail transaction application is launched, a store associate is prompted to start a retail transaction process for purchasing the article 102. The retail transaction process can be started simply by performing a user software interaction, such as depressing a key on a keypad of the computing device 108 or touching a button on a touch screen display of the computing device 108.
Subsequently, the store associate may manually input into the retail transaction application article information. Alternatively or additionally, the store associate may place a handheld device 106 of the POS station 104 in proximity of article 102. As a result of this placement, the POS station 104 obtains article information from the article 102. The article information includes any information that is useful for purchasing the article 102, such as an article identifier and an article purchase price. In some scenarios, the article information may even include an identifier of the security tag 132 attached thereto. The article information can be communicated from the article 102 to the handheld device of the POS station 104 via a short range communication, such as a barcode communication or a Near Field Communication (“NFC”).
In the barcode scenario, article 102 has a barcode 128 attached to an exposed surface thereof. The term “barcode”, as used herein, refers to a pattern or symbol that contains embedded data. Barcodes may include, for example, one-dimensional barcodes, two dimensional barcodes (such as matrix codes, Quick Response (“QR”) codes, Aztec codes and the like), or three-dimensional bar codes. The embedded data can include, but is not limited to, a unique identifier of the article 102 and/or a purchase price of article 102. The barcode 128 is read by a barcode scanner/reader (not shown in
In the NFC scenarios, article 102 may comprise an NFC enabled device 110. The NFC enabled device 110 can be separate from security tag 132 or comprise security tag 132. An NFC communication occurs between the NFC enabled device 110 and the handheld device 106 over a relatively small distance (e.g., N centimeters or N inches, where N is an integer such as twelve). The NFC communication may be established by touching components 102, 106 together or bringing them in close proximity such that an inductive coupling occurs between inductive circuits thereof. In some scenarios, the NFC operates at 13.56 MHz and at rates ranging from 106 kbit/s to 848 kbit/s. The NFC may be achieved using NFC transceivers configured to enable contactless communication at 13.56 MHz. NFC transceivers are well known in the art, and therefore will not be described in detail herein. Any known or to be known NFC transceivers can be used herein without limitation.
After the POS station 104 obtains the article information, payment information is input into the retail transaction application of POS station 104. In response to the reception of the payment information, the POS station 104 automatically performs operations for establishing a retail transaction session with the RTS 118. The retail transaction session can involve: communicating the article information and payment information from the POS station 104 to the RTS 118 via a public network 106 (e.g., the Internet); completing a purchase transaction by the RTS 118; and communicating a response message from the RTS 118 to the POS station 104 indicating that the article 102 has been successfully or unsuccessfully purchased. The purchase transaction can involve using an authorized payment system, such as a bank Automatic Clearing House (“ACH”) payment system, a credit/debit card authorization system, or a third party system (e.g., PayPal®, SolidTrust Pay® or Google Wallet®).
The purchase transaction can be completed by the RTS 118 using the article information and payment information. In this regard, such information may be received by a computing device 108 of the RTS 118 and forwarded thereby to a sub-system of a private network 100 (e.g., an Intranet). For example, the article information and purchase information can also be forwarded to and processed by a purchase sub-system 112 to complete a purchase transaction. When the purchase transaction is completed, a message is generated and sent to the POS station 104 indicating whether the article 102 has been successfully or unsuccessfully purchased.
If the article 102 has been successfully purchased, then a security tag detaching process can be started. During the security tag detaching process, a security tag detacher 112 of the POS station 104 is used to cause actuation of a detaching mechanism of the security tag 132. Once the security tag 132 has been detached from article 102, the customer 140 can carry the article 102 through the surveillance zone without setting off the alarm.

More detailed schematic illustrations of the security tag 132 are provided in
The housing 402 has a housing base 404 and a rotational clip 406. The housing base 404 is formed of a back cover 606 and a front cover 608, which may be ultrasonically welded together during assembly of the security tag 132. Covers 606 and 608 collectively define insert spaces 632, 640, 646, 652 in which various components of the security tag 132 are housed.
In some scenarios, one or more security sensors 618 is(are) disposed within the housing base 404 (as shown in
The rotational clip 406 is pivotally mounted on the housing base 404. As such, the rotational clip 406 can be rotated towards and away from the back cover 606 of the housing 402, as shown by bi-directional arrow 702 of
As shown in
The locking of the rotational clip 406 in its closed position is facilitated by an engagement member 654 thereof. The engagement member 654 comprises an aperture 628 and an angled surface 626. When the rotational clip 406 is moved towards the back cover 606, the engagement member 654 travels through an aperture 638 formed in the back cover 606. Thereafter, the angled surface 626 of the engagement member 654 engages an angled surface 624 of a latch 610. The angled surface 626 slides along angled surface 624 as the rotational clip 406 is further moved in a direction towards the back cover 606. This sliding movement causes the latch 610 to compress a latch spring 612. When an engagement structure 622 of the latch 610 becomes aligned with the aperture 628 formed through the engagement member 654 of the rotational clip 406, the latch spring 612 returns to its less compressed state whereby the engagement structure 622 of the latch 610 travels into the aperture 628 so as to lock the rotational clip 406 in its closed position. Notably, the latch 610 and latch spring 612 are disposed in an insert space 652 of the front cover 608. Also, an audible and/or tactile indictor may be generated and output when the rotational clip 406 is locked in its closed position so that the user knows when the article has been securely coupled to the security tag 132.
The rotational clip 406 can be unlocked by the application of a magnetic field to the latch 610 and the latch spring 612. In this regard, the latch and latch spring are formed of a magnetic material, such as metal. As shown in
The article 102 is retained between the housing base 404 and the rotational clip 406 via a frictional force and a compression force that is applied thereto. The frictional force is applied to the article 102 via two pads 602 and 604 if the article is pulled. In this regard, the pads are both formed of a frictional material, such as TPV material. During use, the article 102 cannot be removed from the locked security tag 132 by an unauthorized person since (s)he is unable to apply a load to the article 102 that is sufficient to overcome at least the frictional force applied by the pads 602, 604. Notably, the pads 602 and 604 have a plurality of purposes: (1) providing said frictional force when the security tag is being used; (2) ensuring that the article is not damaged by the security tag when clamped therein; and (3) ensuring that the article is not stained as a result of being clamped therein.
The compression force is applied to the article 102 by the rotational clip 406 and a cap 616 when the security tag 132 is in its locked position. In this regard, it should be understood that the cap 616 is a spring-loaded cap that can move in two opposing directions represented by arrows 810 of
The cap cover 620 acts as a fixed, unmovable structure for (1) retaining the cap spring 614 within insert space 646 and (2) maintaining the cap spring 614 in alignment with the cap 616. The first function (1) is facilitated by guide structures 650 and snap structures 674, 676. The guide structures 650 enable (1) proper alignment of the cap cover 620 when being assembled with the front cover 608 and (2) facilitate secure, unmovable coupling of the cap cover 620 with the front cover 608. The snap structures 674, 676 provide secure coupling mechanisms which snap into place when the cap cover 620 is pressed towards the front cover 608. In this regard, each snap structure 674, 676 snappingly engages an engagement structure 678 formed on an inner surface of the front cover 608.
In some scenarios, the security tag 132 is designed to expel ink when a sensor (e.g., sensor 2304 of

Notably, the pads 602 and 604 are formed of a TPV material. The TPV material provides a non-slip grip on to an article when compressed between the two pads 1002, 1004. Utilizing a TPV material as the pad material advantageously prevents staining of the eyeglass frames or stems as a result of oxidization, outgassing and/or chemical interaction. Extensive testing has been conducted with various materials, and TPV materials have been found to be well suited for this application.
The TPV pads 602 and 604 are respectively coupled to the rotational clip and cap via an adhesive. The adhesive includes, but is not limited to, glue and/or tape. In some scenarios, a double-sided tape is used to adhere the TPV pads to the tag body. The double-sided tape can include, but is not limited to, a double coasted tape available from 3M of St. Paul, Minn.

Pads 1002 and 1004 are configured to collectively surround and protect an eyeglass frame, temple or stem from damage while the security tag is coupled thereto. In this regard, pad 1002 is coupled to the rotational clip 406 and pad 1004 is coupled to the cap 616 in a manner that ensures their alignment with each other when the security tag is in its closed position (as shown in
Pads 1002 and 1004 are designed to prevent staining of eyewear frames when in use to protect the same. Both pads are shown in
The pads 1002, 1004 are formed from a TPV material. The TPV material provides a non-slip grip on to an eyewear frame or stem when compressed between the two pads 1002, 1004. Utilizing a TPV material as the pad material advantageously prevents staining of the eyeglass frames or stems as a result of oxidization, outgassing and/or chemical interaction.
The TPV pads are respectively coupled to the rotational clip 1008 and cap 1006 via an adhesive. The adhesive includes, but is not limited to, glue and/or tape. In some scenarios, a double-sided tape is used to adhere the TPV pads to the tag body 1006, 1008. The double-sided tape can include, but is not limited to, a double coated tape available from 3M of St. Paul, Minn.
The pads 1002, 1004 comprise protrusions 1010, 1012 extending out and away therefrom. The same or different number of protrusions can be provided on the pads. For example, as shown in
The protrusions 1010, 1012 are spaced apart from each other by a distance selected in accordance with a particular application. The protrusions 1010, 1012 also have an overall pattern selected for ensuring that: (1) the protrusions 1010 align with respective protrusions 1012 when the security tag 1000 is in its closed position; and/or (2) at least one channel is provided between the two pads 1002, 1004 when the security tag 1000 is in its closed position so that gases expelled by the eyeglass wear material are ventilated from the security tag. The overall pattern can have any shape, such as a rectangular shape (shown on pad 1004 in
In
The present solution is also not limited to the security tag architecture shown in
As shown in
During use, an eyewear frame or stem is compressed between the pads 1702, 1802. The security tag 1300 is placed in its locked position via a latch mechanism 1302. The latch mechanism 1302 is similar to a zip tie. In this regard, the rotational clip 1802 can be threaded through an end 1902 of the housing base 1702 and tightened so as to fasten the eyewear 2100 to the security tag 1300. A magnetic field can be applied to release the rotational clip 1802 from the housing base 1702.

In next step 2210, the rotational clip is further rotated. More specifically, the rotational clip is further rotated in step 2210 so that a compressive force is applied to the portion of the article disposed between the pad of the rotational clip (e.g., pad 1002 of
In some scenarios, the compressive force is applied by: rotating the rotational clip until an engagement member (e.g., engagement member 654 of
Sufficient retention of the article is provided in 2212 such that the security tag is unable to slip off of the article and/or be forcibly pulled off of the article, while staining of the article as a result of oxidization, outgassing and/or chemical interactions is also being prevented. The sufficient retention is facilitated by the compression of the article between the two pads and/or the provision of a non-slip grip of the security tag's pads to the article. The stain prevention is facilitated via the use of pads formed of a TPV material. In outgassing scenarios, venting of released gasses may be provided by allowing the gasses to pass through one or more channels formed between the first and second pads into a surrounding environment.
At some later time, a decision is performed to determine if the security tag should be decoupled from the article. If it is determined that the security tag should not be decoupled from the article [2214:NO], then method 2200 waits for a period of time before performing a second iteration of decision.
In contrast, if it is determined that the security tag should be decoupled from the article [2214:YES], then steps 2216-2220 are performed. Step 2216 involves applying a magnetic field to the latch so as to cause the latch to disengage the rotational clip. Compressing the rotational clip by the operator to relive the force from a cap spring may be required to allow the latch to travel under the magnetic force. Step 2218 involves rotating the rotational clip in a direction away from the housing base of the security tag. Step 2220 involves removing the article from the security tag. Thereafter, step 2222 is performed where method 2200 ends or is repeated using another article.
