A security seal for assembly onto a staple to seal a hasp onto the staple, said seal being formed of a single piece of injection molded plastic and comprising a flexible strap, a fastener support body at each end of the strap, one of said bodies having an aperture in the upper surface leading to a set of resilient locking fingers, the other body having an upwardly projecting stud member positioned and dimensioned for locking engagement in said socket when the strap is folded at a medial portion to move said fastener support bodies together, said fastener support bodies each having a shape in cross-section perpendicular to the axis of the strap which provides a projecting portion which is positioned to extend radially from the axis of the engaged stud and socket generally at an angle of 45.degree. to the longitudinal axis of the folded strap and away from said folded strap, said bodies and said projecting portions being so dimensioned in relation to a staple and hasp with which the seal is to be assembled that when the seal is assembled with the staple so that the fastener bodies are positioned on opposite sides of the staple and with the stud extending through the staple into engagement with the socket and then rotated about the axis of the assembled fasteners from an initial assembled position in which the folded strap projects outwardly from the surface of the hasp to a position in which it lies against the surface of the hasp, said projecting portions frictionally and resiliently engage the surface of the hasp during such rotation in a manner such that the seal can snap from the initial assembled position to the final assembled position, whereby said projecting portions resist rotation of the seal away from the final assembled position.
A security seal for assembly onto a staple of a staple and hasp assembly of predetermined dimensions in which the staple protrudes through a slot in the hasp, said seal comprising a pair of seal bodies connected by a flexible member, said body portions each having a fastener carrying face on corresponding sides so positioned that when the flexible member is bent to a U-shape, the faces are closely adjacent and facing each other and may be positioned on opposite sides of said staple, one of said body portions having an internal socket opening to the face thereof, the other body portion having a stud protruding from the face thereof, the stud and socket being so dimensioned and being so positioned as to enable the stud to extend through said staple into locking engagement with the socket with the faces of the body portions being spaced apart by substantially the thickness of the staple, said body portions having substantially flat end portions adjoining the faces and which are generally perpendicular thereto and are substantially co-planar when the stud and socket are engaged and are so positioned in relation to the axis of the assembled stud and socket that the plane of said ends is, when the seal is assembled with a staple and hasp of said predetermined dimensions, disposed closely adjacent to the hasp to maintain the seal in a predetermined orientation in relation to the hasp.
A seal assembly comprising a hasp, a staple protruding through a hasp aperture, and a seal assembled onto the protruding portion of the staple, said seal comprising two body portions disposed on opposite sides of the staple and locking means extending from one body portion into locking engagement with the other body portion, said body portions being connected by a flexible shackle, and means on the body portions resiliently maintaining said body portions in a predetermined orientation in relation to the surface of said hasp.
A seal assembly comprising a container having a hasp with a slot, a staple protruding through the slot, said hasp being inclined slightly outwardly from the adjacent surface of the container and being resiliently movable inwardly, and a seal assembled into the protruding portion of the staple, said seal comprising a pair of body portions disposed on opposite sides of the staple and having locking means extending through the staple from one body portion into locking engagement with the other body portion, said body portions being connected by a flexible shackle, at least one body porton having a cross-sectional shape in a direction perpendicular to the hasp surface which provides a portion adjacent the hasp surface which is sufficiently far from the axis of the locking means that rotation of the seal around the fastener axis is effected only by engagement of said portion with the hasp surface to cause resilient movement of said hasp inwardly.
A security seal assembly, comprising a hasp, a staple arranged to protrude through the hasp, and a seal for assembly onto the staple, said seal comprising a flexible strap, a fastener support body at each end of the strap, one of the bodies having an aperture in a surface leading to a set of resilient fingers, the other body having a projecting stud positioned and dimensioned for extending through the staple into locking engagement in said socket when the strap is folded at a medial portion to move said fastener support bodies together, said fastener support bodies each having a shape in cross-section perpendicular to the axis of the stud which provides a corner on the end of each body, said bodies being so dimensioned in relation to the staple and hasp that when the seal is assembled with the fastener bodies positioned on opposite sides of the staple and with the stud extending through the staple into locking engagement with the socket and then rotated about the axis of the stud from an initial position in which the folded strap projects outwardly from the surface of the hasp to a position in which the strap lies against the surface of the hasp, one set of support body corners frictionally and resiliently engages the surface of the hasp during such rotation thereby allowing the seal to snap from the initial assembled position to a final assembled position, whereby the support body corners resist rotation of the seal away from the final assembled position.
