Abstract
Abstract A safety closure device for threaded neck bottles which can not be opened by young children because to open it, it is necessary to simultaneously press and turn the closure cap. The closure cap is made of two parts housed the one within the other, the outer one comprising a guarantie ring and ratching formations cooperating with ratching formations of the inner part. Driving members provided on said outer and inner parts coopering together only when these two parts are displaced relatively against a spring means.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
148 words
A safety closure cap characterised by the fact that it comprises a cup and an internal part, which is retained within said cup but submitted to a resilient action tending to displace it toward the outside of said cup; corresponding ratching formations on the internal wall of the cup and on the outside wall of the internal part, cooperating to drive the internal part in rotation with the cup in only one direction of rotation, whatever the axial position of the internal part is with respect to the cup; and by the fact that corresponding driving formations provided on the internal surface of the cup and on the outside surface of the internal part, cooperate in order to drive the internal part through the cup in the other direction of rotation only when the internal part is axially displaced with respect to the cup against the resilient action.
Claim 2
Dependent Claim
148 words
A safety closure cap characterised by the fact that it comprises a cup and an internal part, which is retained within said cup but submitted to a resilient action tending to displace it toward the outside of said cup; corresponding ratching formations on the internal wall of the cup and on the outside wall of the internal part, cooperating to drive the internal part in rotation with the cup in only one direction of rotation, whatever the axial position of the internal part is with respect to the cup; and by the fact that corresponding driving formations provided on the internal surface of the cup and on the outside surface of the internal part, cooperate in order to drive the internal part through the cup in the other direction of rotation only when the internal part is axially displaced with respect to the cup against the resilient action.
Claim 3
Dependent Claim
37 words
Cap according to claim 1, characterised by the fact that the internal part comprises a spring piece, this spring piece carrying resiliently deformable lugs, fast with a ring, and extending out of the plan of said ring.

Dependent Claim
24 words
Cap according to claim 2, characterised by the fact that the resilient lugs of the internal part abutts against the bottom of the cup.
Claim 5
Dependent Claim
31 words
Cap according to claim 1, characterised by the fact that the upper face of the internal part carries resilient lugs extending toward the center and toward the bottom of the cup.
Claim 6
Dependent Claim
22 words
Cap according to claim 3, characterised by the fact that the spring piece is located between the cup and the internal part.
Claim 7
Dependent Claim
30 words
Cap according to claim 5, characterised by the fact that the spring piece carries, spaced around an outside skirt, the ratching formations cooperating with the ratching formations of the cup.
