The invention relates to a security seal and, more preferably, to a one-piece security seal having a tail end, a receptacle end and a middle portion therebetween.
Plastic seals are used extensively within the trucking industry and do not vary significantly from vendor to vendor, with the primary market advantage being cost. The purpose of a plastic seal is generally to provide tamper evidence by breaking in a designed way when the cargo is accessed by anyone. The seal has a unique identifier and cannot be resealed once broken, providing immediate visual evidence that the load has been opened, or at the very least tampered with.
When a load is transported, tampering and theft are always concerns. While current seal designs generally deter theft by providing tamper evidence, it is conceivable that there are ways to bypass the tamper evident features of market seals by spinning the seal tip in its sealed position, or pulling the seal tail in different directions when it is in the sealed position, causing the seal tip to move side-to-side in the receptacle. When security seals on the market are tested for failure modes, some fail before their rated strengths when the seal tail is pulled in various directions.
In one construction, the disclosure provides a security seal having a receptacle including a bore with an exit end, at least one tab extending into the bore and an end plate having thereon a saddle; a tip having a cutout therein; and a middle portion between the receptacle and the tip, wherein the tip is insertable into the bore and engageable with the at least one tab and wherein the end plate is moveable with a living hinge to block the exit end and to insert the saddle into the cutout.
In another construction, the disclosure provides a one-piece security seal having: a tip having a slot; a middle portion; and a receptacle having a bore, at least one tab extending into the bore and an end plate, the bore having an exit end and the end plate having thereon a saddle; wherein the security seal has an open position wherein the tip is not positioned in the receptacle and the end plate is not positioned in the exit end and wherein the security seal has a closed position where the tip is positioned in the bore such that the saddle is housed in the slot, the end plate closes off the exit end and the tip is prevented from moving axially or radially within the bore.
In another construction, the disclosure provides a security seal having a one-piece plastic seal having a tail portion, a receptacle portion, and a middle portion therebetween, wherein the tail portion includes a tip having a rectangular portion and having a slot and wherein the receptacle portion includes a receptacle and a cap, the receptacle having a bore and having extensions extending inwardly into the bore adapted to engage with the rectangular portion of the tip, the cap having a saddle, and the cap adapted to be moved into an orientation such that the saddle is positioned in the slot and such that the cap closes off an end of the bore.
In another construction, the disclosure provides a security seal having a receptacle including a bore having an exit end and including a cap having a saddle; a tip having a slot therein; and a middle portion between the receptacle and the tip, wherein the tip is insertable into the bore and wherein the cap is moveable with a living hinge from an open position non-blocking the exit end of the bore to a closed position blocking the exit end of the bore with the saddle positioned in the slot.
In another construction, the disclosure provides a security seal having a receptacle including a bore and an end plate having thereon a saddle; a tip having a slot therein; and a middle portion between the receptacle and the tip, wherein the tip is positionable into the bore such that the saddle is positioned in the slot to prevent movement of the tip in the bore.
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 security seal 10 includes a tail end 12, a receptacle end 14, a middle portion 16 therebetween and a longitudinal axis 18. The tail end 12 includes a tip 20, a break point aperture 22 as is known in the art and a plurality of ridges 24. The tip 20 is adjacent to a narrow portion 26 which includes the break point aperture 22. The ridges 24 are on a wider portion 28 which is adjacent to the narrower middle portion 16.
As best shown in
Referring back to
The ridges 24 are preferable triangular shaped in cross-section, however other shapes can also be utilized. The ridges 24 are designed to provide a texture to aid the inserting of the tip 20 into the receptacle end 14.
The middle portion 16 is generally rectangular with a unform width, however, other shapes and widths can also be utilized.
The receptacle end 14 includes a wide portion 50, a receptacle 52 adjacent to the wide portion 50 and preferably secured to the wide portion 50 with a welding ridge 54 and terminates in a moveable saddle portion 56 which is connected to the receptacle 52 with a living hinge 58.

In operation and referring to
The single piece security seal 10 has anti-tamper features found in multiple piece security seals. The saddle 86 engaging with the head 30 prevents both side-to-side and rotational movement. The living hinge 58 enables the saddle portion 86 to be molded while maintaining a single piece design. The rectangular shape of the tip 20 engaging with the tabs 66 is a further anti-tamper feature.
Various features and advantages of the invention are set forth in the following claims.
