The present disclosure is in the field of cargo security seals and, more particularly, band seals for attachment to a locking hasp such as on a trailer door or a tanker hatch.
Band seals are commonly used to secure doors and hatches. In particular, band seals are used to secure trailer doors and tanker trailer hatches by threading the one-time use band seal through a locking hasp. The purpose of the band seal is to show evidence of tampering and deter unauthorized access to contents such as cargo in the trailer or tanker. Band seals have historically been constructed of plastic or tin/metal materials. They can be removed by hand due to their relatively low break strength of typically 20 to 100 lbf.
In one construction, the disclosure provides a band seal including a strap including a head portion, a middle portion and a tail portion, a retainer, an adhesive pad and a release liner secured to the adhesive pad. The band seal is positionable into three positions including a pre-attached position wherein the middle portion of the strap is in a non-looped orientation, a temporary position wherein the middle portion of the strap is in a looped orientation and the retainer holds the middle portion in this looped orientation with the tail portion being concentric with the middle portion, and an attached position wherein the release liner is removed from the adhesive pad and at least a part of the tail portion is secured to the adhesive pad.
In another construction, the disclosure provides a band seal including a strap having a head portion, a tail portion, a pair of shoulders, and a slot, the slot dimensioned to enable the head portion to pass therethrough, and the shoulders adapted to engage a portion of the strap adjacent the slot to hold the strap in a temporary position, an adhesive pad on the strap adjacent the shoulders and a release liner secured to the adhesive pad and removable from the adhesive pad after the strap is in the temporary position to enable the tail portion to adhere to the adhesive pad.
In another construction, the disclosure provides a band seal including a strap having a head portion, a tail portion and a restrainer, an adhesive pad on the strap and a release liner secured to the adhesive pad and removable from the adhesive pad to detach from the strap and to enable at least a part of the tail portion to adhere to the adhesive pad, the first release liner having identification indicia thereon. The restrainer is adapted to hold the strap in a temporary position and adapted to align the tail portion with the adhesive pad before the at least a part of the tail portion adheres to the adhesive pad.
In another construction, the disclosure provides a band seal including an elongate strap having a head portion, a tail portion, a pair of shoulders, identification indicia and a slot, the slot dimensioned to enable the head portion to pass therethrough and the shoulders adapted to engage a portion of the strap adjacent the slot and hold the strap in a temporary position, an adhesive pad on the strap adjacent the shoulders, a first release liner secured to the adhesive pad and removable from the adhesive pad to detach from the strap after the strap is in the temporary position to enable at least a part of the tail portion to adhere to the adhesive pad, the first release liner having identification indicia thereon and a second release liner secured to and removable from the first release liner to enable the first release liner to be secured to a surface.
In another construction, the disclosure provides band seal comprising a strap having a head portion, a middle portion, and a tail portion, the middle portion having indicia thereon, and the tail portion having a first part and having a second part with indicia thereon and being releasably secured to the first part; an adhesive pad on the strap; and a release liner secured to the adhesive pad and removable from the adhesive to enable the first part of the tail portion to adhere to the adhesive pad; wherein the second part of the tail portion is optionally removable from the band seal after the first part of the tail portion is adhered to the adhesive pad.
Other aspects of the disclosure will become apparent by consideration of the detailed description and accompanying drawings.
Before any constructions of the disclosure are explained in detail, it is to be understood that the disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The disclosure is capable of other constructions and of being practiced or of being carried out in various ways.

The strap 22 of the band seal 20 is preferably manufactured from a semi-rigid plastic extrusion such as strapping currently used in the shipping industry, however, any mass scale or similar plastic, ferrous, non-ferrous or composite material can also be utilized for economies of scale such as any band type strip. The adhesive pad 38 is preferably manufactured from acrylic or urethane using an adhesive such as very high bond (VHB) from 3M or others. The release liners 44 and 52 are preferably manufactured from polyethylene, polypropylene, polytetrafluoroethylene, polyester, acetyl, polyvinyl chloride, or silicone.
The strap 22 can be colored for unique identification or branding.
Due to the compact form factor of the band seal 20, multiple band seals take up far less space when stored as compared to other band seals. For example, a carton of 1,000 molded prior art plastic truck seals measures approximately 11″×11″×9.″ A carton of 1,000 band seals 20 will measure approximately 12″×12″×2″.

In this looped temporary position, the user can grasp the band seal 20 with their thumb and index finger using the finger grip 30 if needed as shown in
The now detached release liner 44 acts as an ID tag for tracking purposes. As shown in
Evidence of tampering or attempts to remove the band seal 20 will be clearly indicated by stress or damage to the adhesive pad 38 and/or damage to the strap 22.

An adhesive pad 88 is positioned adjacent the head portion 74. The adhesive pad 88 is preferably rectangular as shown in the drawings, however, other geometries can also be utilized.
Similar to the band seal 20, with the band seal 70, the tip 78 and head portion 74 are adapted to be pulled through the slot 86 such that the shoulders 82 engage the strap 72 adjacent the slot 86 and hold the strap 72 in this looped position. The shoulders 82 prevents the head portion 74 from slipping back through the slot 86. The shoulders 82 also enable the alignment of the first part of the tail portion 76A with the adhesive pad 88.
The band seal 70 includes a release liner 90 releasably covering the adhesive pad 88. The middle portion 75 of the strap 72 includes indicia 92 such as serial numbers, customer logo, bar code, QR or other identifying data or indicia, for example. The tail portion 76B includes indicia 94 such as serial numbers, customer logo, bar code, QR or other identifying data or indicia, for example. Preferably the indicia 92 and 94 are the same. Perforations 96 on the strap 72 separate the first and second parts of the tail portion 76A and 76B. Optionally, there is adhesive on the tail portion 76B on the side opposite the indicia 94.
The installation and use of the band seal 70 is similar to that of the band seal 20 described above with the following differences. In this looped temporary position, the user can grasp the seal 70 with their thumb and index finger using the finger grip 80 if needed. The user pinches the first part of the tail portion 76A to the strap 72 with the release liner 90 therebetween such that the tail portion 76, strap 72 and release liner 90 are all concentrically aligned one atop each other so that the first part of the tail portion 76A will be properly and completely adhered to the adhesive pad 88. The user pulls an end 98 of the release liner 90 while maintaining the pinch. The release liner 90 pulls away from the adhesive pad 88 disengaging entirely from the seal 70. The user further pinches the first part of the tail portion 76A to the adhesive pad 88 to secure the band seal 70 in its attached position. If desired, the user can remove the second part of the tail portion 76B by tearing at the perforations 96. The second part of the tail portion 76B with indicia 94 can then be secured to items such as a tracking form, report, shipping documentation or the like.
