Definitions

  • the present invention relates to security seals and is more particularly, although not exclusively, concerned with the sealing of meter covers using screw arrangements.
  • a screw In current electricity meters, a screw is used to secure a cover thereof and it is then sealed by passing Bowden cable through a cross-hole provided in the screw head and into a mating hole or slot in an adjacent portion of the cover and secured to restrict subsequent rotational movement of screw.
  • two sealing tags may be used - one tag being fixed by the screw and the other being slotted into the fixed tag to cover a standard screw head, the tags being sealed with Bowden cable.
  • the loose sealing tag can be misplaced when authorised opening of the cover takes place
  • FR-A-2,216,802 provides a security seal according to the preamble of claim 1 for a screw wherein an integrally formed moulding of a piece part to be secured includes a hinged member which prevents access to the screw without breaking a sealed tab. If the seal is damaged, the whole piece part moulding must be replaced.
  • a security seal for a screw according to claim 1 comprising a strip of material, having:-
  • each hinge portion can comprise a reduced thickness section within the strip of material. It is preferred that the cap portion is connected to the body portion by means of a second and a third hinge.
  • the body portion, the tab portion and the cap portion are integrally formed, and may comprise a substantially flat strip of material.
  • the strip of material comprises a plastics material, preferably, polypropylene.
  • the strip of material may be substantially elongate, and the body portion is substantially rectangular.
  • Wire means may further be provided for securing the cap portion over the body portion, the wire means passing through the second aperture over the cap portion after the tab portion has engaged the third aperture.
  • an electricity meter comprising a housing and a cover, the cover having a recess in which a security seal as described above is located.
  • a method of securing a cover using a security seal as described above, the cover having a recess formed therein for receiving the seal comprising the steps of:-
  • FIG. 1 illustrates a seal 10 in accordance with the present invention.
  • the seal 10 comprises a single integral moulding 12 having a body portion 14 with a hole 16, a cap portion 18 with a cap 20 and a slot 22, and a tab portion 24 with a hole 26 formed therein.
  • Hinges 28, 30, 32 are also formed as shown using well-known injection moulding techniques.
  • the hole 16 of body portion 14 receives a screw (not shown) and then, as the screw is tightened, the seal 10 is folded along hinge 28 and hinge 30 as the body portion 14 is drawn to the base of a recess (not shown).
  • the cap portion 18 can then be folded over along hinge 32 so that the cap 20 thereof covers the screw head (not shown) and tab portion 24 is inserted into slot 22 of cap portion 18, such that hole 26 is above the slot 22, and sealing wire (not shown) can be inserted into hole 26 in the tab portion 24.
  • the tab portion 24 When the screw 44 has reached the end of its travel, the tab portion 24 is upstanding and is substantially perpendicular to body portion 14, as shown in Figure 3, and cap portion 18 is in a position, hinged about hinge 30, such that it can be folded along hinge 32 in the direction of arrow 54 so that cap 20 of cap portion 18 fits over head 56 of screw 44 and slot 22 fits over end 58 of the upstanding tab portion 24 with hole 26 being above the slot 22.
  • the assembled seal 10 is shown in Figure 4 where a sealing wire 60 has been passed through hole 26 to retain the cap portion 18 below the hole 26.
  • Figures 5 to 7 illustrate an electricity meter 70 having a housing 72 to which a cover 74 is which is to be sealed.
  • the cover 74 corresponds to the cover 42 of Figures 2 to 4 and Figures 5 to 7 correspond to respective ones of Figures 2 to 4.
  • the seal 10 is placed on the cover 74 over a recess therein (not shown). Screw 44 is tightened and the seal 10 folds along hinges 28 and 30 to the position shown in Figure 6 and the cap portion 18 is folded over along hinge 32 so that hole 26 of tab portion 24 extends through slot 22 so that the sealing wire 60 can be threaded through the hole 26 and sealed in a loop with a crimp 76 as shown in Figure 7.
  • the seal 10 of the present invention can also be used in a shallow recess 80 formed in a cover 82 as shown in Figures 8 to 10.
  • the recess 80 has a hole 84 formed in its base for receiving a screw 86.
  • the seal 10 is initially placed over the recess 80 such that the body portion 14 lies over the recess 80.
  • Screw 86 is placed into hole 16 and screwed down into hole 84 formed in the bottom of the recess 80 in the direction indicated by arrow 88.
  • the body portion 14 of the seal 10 is drawn down towards the bottom of the recess 80.
  • tab portion 24 folds up in the direction indicated by arrow 90 along hinge 28
  • cap portion 18 folds up in the direction indicated by arrow 92 along hinge 30. Again, this folding action is produced by the shape of the recess 80.
  • the tab portion 24 When the screw 86 has reached the end of its travel, the tab portion 24 is upstanding and is substantially perpendicular to body portion 14, as shown in Figure 9, and cap portion 18 is in a position, hinged about hinge 30, such that it can be folded along hinge 32 in the direction of arrow 94 so that cap 20 of cap portion 18 fits over head 96 of screw 86 and slot 22 fits over end 58 of the upstanding tab portion 24 with hole 26 being above the slot 22.
  • the assembled seal 10 is shown in Figure 10 where a sealing wire 60 has been passed through hole 26 to retain the cap portion 18 below the hole 26 as before.
  • the cap 20 of cap portion 18 is sized to accommodate the head of the screw used.
  • the screw 44, 86 can be a conventional screw of a suitable length for the hole 46, 84 in the base of the recess 40, 80 formed in the cover 42, 82.
  • the screw 44, 86 may be a standard slotted cheese head screw.
  • the depth of the recess within which the seal 10 of the present invention is to be used must be at least as deep as the thickness of the body portion 14 thereof. This has the effect of preventing access to the body portion 14 within the recess.
  • the body portion 14 of the seal 10 is substantially rectangular and fits within a substantially rectangular recess.
  • any other suitable shape could be used for the body portion 14 and/or recess with the proviso that rotation of the seal within the recess is to be prevented.
  • the seal of the present invention has the advantage that, in use, it is captive, that is, it is retained in its recess by the screw. Furthermore, the assembled seal provides an anti-tamper or tamper evident device.
  • the seal 10 can be made of any suitable thermoplastic material, for example, polypropylene, which allows the formation of the hinges 28, 30, 32 and which allows the hinges to be repeatedly flexed without fracturing.
  • a thermoplastic material By using a thermoplastic material, the seal is simple and inexpensive to produce. Any standard screw can be used which makes it inexpensive compared with the cross-drilled screw described above.
  • thermoplastic materials may also be suitable for manufacturing the seal.
