Abstract
Abstract A safety closure for a container, e.g. an aerosol can, has a cap which covers the operative end of the can. An intermediate element is secured to the open end of the can and a breakable warranty tie or link immobilises the cap relative to the intermediate element to ensure that the container and its contents are tamper-proof prior to sale.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
142 words
A tamper-proof safety closure for an aerosol container and cap assembly comprising an axially elongated cylindrical container having an end wall of progressively decreasing diameter culminating in a neck, a cap having a cylindrical wall, an intermediate component between the cap and container and having a cylindrical side surface of substantially larger diameter than the neck and forming a sliding surface for the cap, first snap-action resilient means for securing the intermediate component to the cap, second snap-action resilient means for permanently locking the intermediate component to the neck, an underside bearing surface on the intermediate component bearing directly on the end wall, said first resilient means being independent of said bearing surface and including a ring adapted to separate by fracture from another portion of the closure to enable the cap to slide axially relative to the intermediate component upon separation.
Claim 2
Dependent Claim
142 words
A tamper-proof safety closure for an aerosol container and cap assembly comprising an axially elongated cylindrical container having an end wall of progressively decreasing diameter culminating in a neck, a cap having a cylindrical wall, an intermediate component between the cap and container and having a cylindrical side surface of substantially larger diameter than the neck and forming a sliding surface for the cap, first snap-action resilient means for securing the intermediate component to the cap, second snap-action resilient means for permanently locking the intermediate component to the neck, an underside bearing surface on the intermediate component bearing directly on the end wall, said first resilient means being independent of said bearing surface and including a ring adapted to separate by fracture from another portion of the closure to enable the cap to slide axially relative to the intermediate component upon separation.

Claim 5
Dependent Claim
50 words
A closure according to claim 1, wherein the ring is detachably connected to the cap and provided with a projection extending radially inwardly, the projection being arranged to abut against the intermediate component under the influence of a force tending to separate the container axially from the ring cap assembly.
Claim 6
Dependent Claim
39 words
A closure according to claim 1, wherein the ring is detachably connected to the intermediate component and provided with a projection extending radially inwardly, the cap having an outer surface formed with a recess arranged to receive the projection.
Claim 7
Dependent Claim
58 words
A closure according to claim 1, wherein the ring is frangibly linked to the intermediate component, the cap being provided with means secured to the ring for holding the cap axially, and with means for separating the ring from the intermediate element upon displacement of the cap relative to the assembly consisting of the intermediate component and ring.
Claim 8
Dependent Claim
29 words
A closure according to claim 6, wherein the frangible link comprises several breakable elements which are distributed circumferentially and arranged to break consecutively upon rotational displacement of the cap.
Claim 9
Dependent Claim
62 words
A closure according to claim 6, wherein the cylindrical wall of the cap has at least one lower extension arranged for insertion into an annular space between the intermediate component and the ring, and to be secured permanently to the ring by a groove and rim joint, and wherein the frangible link comprises at least one bridge element spanning said annular space.
Claim 10
Dependent Claim
26 words
A closure according to claim 8, wherein a cutting edge is formed on one said extension and arranged to come into contact with a bridge element.
Claim 11
Dependent Claim
47 words
A closure according to claim 8, characterized by a notch formed in the surface of one said extension and arranged to come into engagement with a bridge element after the bridge element has been severed, in a manner to lock the cap for rotation with the ring.
Claim 12
Dependent Claim
22 words
A closure according to claim 6, wherein an indication becomes visible after a displacement of the cap sufficient to cause the fracture.
Claim 13
Dependent Claim
39 words
A closure according to claim 11, wherein a window and a resilient tab are formed, one in the ring and the other in the cap, and arranged to come into alignment with each other to form said visible indication.
Claim 14
Dependent Claim
20 words
A closure according to claim 9, wherein the extension is formed with a blunt edge opposed to the cutting edge.
Claim 15
Dependent Claim
28 words
A closure according to claim 6, wherein after fracture of the link, the ring forms an intact annular rim on the cap, which is visible from the outside.
Claim 16
Dependent Claim
127 words
A closure according to claim 1, wherein the base of the cap comprises a part arranged for relative displacement by tilting about the vertical axis of the closure and by a downwardly extending partition formed on the lower surface of the said part of the cap, a sliding rod traversing the skirt of the cap is arranged to exert a horizontal thrust on the said partition to cause said tilting, the said rod being arranged to assume at least two angular positions by rotation on its axis, and means for permitting or preventing displacement of the displaceable part, depending on whether it occupies one or the other of the said positions, the link being arranged to secure the rod in the locked position of the displaceable part.
Claim 17
Dependent Claim
40 words
A closure according to claim 15, wherein the link comprises a tearable tab received in a notch formed in the outer end of the rod and secured to the skirt to prevent the rotation of the rod on its axis.
Claim 18
Dependent Claim

A closure according to claim 15, characterized by the presence at the inner end of the rod, at two positions arranged to be placed in alignment with the partition according as to whether the rod occupies one or thE other of the aforesaid positions, of a square step having a vertical face in abutment against the partition and a horizontal face situated at a distance from the lower end of the partition, and two fins adapted to enflank the partition, the lower extremity of the partition coming into contact with the base of the groove formed by the said fins.
Claim 19
Dependent Claim
16 words
A closure according to claim 1, wherein the ring is detachably connected to the intermediate component.
Claim 20
Dependent Claim
