## Abstract

A child-resistant closure (10) is provided and comprises a base (15) and a lid (20). The base has an inner skirt (50) and an outer skirt (25). The closure has locking means (81, 86) tor releasably locking the lid in a closed position. The outer skirt has one or more pressing zones (80, 85) which can be pressed to release the locking means. The inner skirt has one or more cut-outs (65, 70) in register with the or each pressing zone whereby to allow greater deflection thereof.

## Claims

### Claim 1

A child-resistant closure comprising a base and a lid connected by a hinge, the base having an inner skirt and an outer skirt depending from a deck, their free ends terminating at approximately the same position, the closure further having locking means for releasably locking the lid in a closed position, the outer skirt having one or more pressing zones which can be pressed to release the locking means in a radially inward movement, characterised in that the inner skirt has one or more cut-outs, which extend through the inner skirt, in register with the one or more pressing zones whereby to allow greater deflection thereof.

### Claim 2 (depends on 1)

A closure as in claim 1, in which the locking means comprise a locking lug movable to an unlocked position by the pressing zone.

### Claim 3 (depends on 2)

A closure as in claim 2, in which the lid has one or more slots for receiving each locking lug and in the locked position the one or more lugs project through the one or more slots.

### Claim 4 (depends on 1)

A closure as in claim 1, in which each pressing zone comprises a recessed panel.

### Claim 5 (depends on 1)

A closure as in claim 1, in which the pressing zone/s comprise a pressing pad.

### Claim 6 (depends on 1)

A closure as in claim 1, in which the outer skirt comprises two pressing zones and the inner skirt comprises two corresponding cut-outs.

### Claim 7 (depends on 1)

A closure as in claim 1, in which the inner skirt comprises retention means for securing the closure to a container.

### Claim 8 (depends on 7)

A closure as in claim 7, in which the retention means comprise a locking bead.

### Claim 9 (depends on 8)

A closure as in claim 8, in which the locking bead is segmented.

### Claim 10 (depends on 1)

A closure as in claim 1, in which the cut-out comprises a notch.

### Claim 11 (depends on 10)

A closure as in claim 10, in which the notch extends over substantially the full height of the inner skirt.

### Claim 12 (depends on 1)

A closure as in claim 1, in which the cut-out comprises a window.

### Claim 13 (depends on 1)

A closure as in claim 1, in which the inner skirt is split into two identical arcuate sections which are positioned diametrically opposed to each other and separated by two generally U-shaped cut-out sections, and in which the free end of the inner skirt sections extend so that they terminate at approximately the same position as the outer skirt.

### Claim 14 (depends on 1)

A closure as in claim 1, in which the deck includes a spout section.

### Claim 15 (depends on 1)

The closure as in claim 1 in combination with a container.

### Claim 16 (depends on 1)

The closure of claim 1, wherein the one or more cut-outs divide the inner skirt into one or more arcuate sections.

### Claim 17

A child-resistant closure comprising a base and a lid connected by a hinge, the base having an inner skirt and an outer skirt depending from a deck, their free ends terminating at approximately the same position, the closure further having a lock for releasably locking the lid in a closed position, the outer skirt having one or more pressing zones which can be pressed to release the lock in a radially inward movement, characterised in that the inner skirt has one or more cut-outs extending through the inner skirt in register with the one or more pressing zones whereby to allow greater deflection thereof.

### Claim 18 (depends on 17)

The closure of claim 17, wherein the one or more cut-outs divide the inner skirt into one or more substantially identical arcuate sections.
