Abstract
Abstract Security clip for discouraging theft of goods, comprising an ink-filled reservoir (10) having an outer circumference, a pin (5) and a pin-receiving member forming part of an electronic security system. The pin (5) is connected to the reservoir (10), and the reservoir has a rupture edge (6) which is situated between the pin and the circumference of the reservoir (10). The reservoir (10) consists of a dish (1) and a covering plate (2) which has a sloshing edge (7) that extends down into the dish (1). The outside (8) of the sloshing edge and the inside (9) of the dish (1) cooperate in an airtight way such that upon pushing the covering plate (2) towards the dish (1) a pressure increase is created within the reservoir (10). Thus, when the rupture edge is ruptured, the ink is distributed by this over-pressure.

Claim 4
Dependent Claim
34 words
Security clip according to claim 1, in which the reservoir (10) consists of a dish (1) and a covering plate (2) which has a sloshing edge (7) that extends down into the dish (1).
Claim 5
Dependent Claim
49 words
Security clip according to claim 3, in which the outside (8) of the sloshing edge and the inside (9) of the dish (1) cooperate in an airtight way such that upon pushing the covering plate (2) towards the dish (1) a pressure increase is created within the reservoir (10).
Claim 6
Dependent Claim

Claim 8
Dependent Claim
39 words
Security clip according to claim 5, in which the pin (5) is fitted into a plate (3) which is fastened in a cavity (11) of the covering plate (2), which cavity (11) is surrounded by the rupture edge (6).
Claim 9
Dependent Claim
36 words
Security clip according to claim 3, in which the outer wall (13) of the covering plate (2) and the upper part (14) of the dish fit together in such a way that they are ultrasonically weldable.
Claim 10
Dependent Claim
100 words
Process for manufacturing a security clip, comprising the steps of: a) passing a pin (5) through an opening (4) in a plate (3), b) fastening plate (3) into a cavity (11) in a covering plate (2), c) filling a dish (1) with ink, d) fitting the covering plate (2) into the dish (1) in such a way that an airtight seal is formed, e) pushing the covering plate (2) into the dish whilst maintaining the airtight seal and thereby creating a higher pressure in the dish (1), and f) fastening the covering plate (2) hermetically sealed on the dish (1).
