Definitions

  • This invention relates to an anti-loose closure of the so-called "child-proof” type that is designed to prevent it from being opened by a child and to be used, in particular, for closing noxious substances bottles or containers, wherein the closing cap proper is an aluminium cap and is provided with a safeguard strip.
  • Child-proo.f closures are composed of an inner cap which is the sealing closure for the bottle or container concerned, and an outer cap that covers the inner cap and is nprmally free rotatable with respect to the inner cap but may be brought into engagement with this latter to cau se it to rotate, thereby threadingly opening or closing it.
  • the closure according to this invention is of simple and rather inexpensive conception and it has a safeguard strip provided on the inner cap which is removable or breakable on first opening of the associated container, while retaining the anti-loose or unthreading-preventing, requisite of this type of closure.
  • The.”child-proof" closure according to this invention has an inner cap that is provided with an annular rib located at such a level thereon as to interfere with an abutment surface on the outer cap to prevent this latter from being taken-off but to permit it to be moved in an axial direction as is necessary for bringing said outer cap from a disengaged position with respect to the inner cap, to an engaged position therewith to cause the inner cap to rotate and, thus, to be either threaded out or threaded down, the inner cap being extended in an out ward direction beyong the abutment surface on the outer cap so as to form a safeguard-strip that is detachable along a tear or break line formed immediately below said annular rib.
  • the means permitting the outer cap to engage with the inner cap comprise a knurled region provided inside the skirt of the outer cap near the bottom thereof, an external knurled region provided on the inner cap at the upper end of its skirts, and fin-shaped formations that project out of the bottom of the outer cap to interfer with the lower outer wall of the inner cap, and which are such as to hold the two knurled regions in a spaced apart relationship, but to resiliently yeld under the effect of an axial pressure so as to cause said two knurled regions to be brought into engagement with one another.
  • shown at 1 is the neck of a container, such as a bottle, on which an aluminium closure cap 2 is clamped, the cap 2 being provided with a thread 3 for enabling the cap to be threadingly applied onto, and removed from the bottom neck, on which neck the cap 2 is clamped in place by means of a safeguard strip 4 that has to be detached along a rupture line 5 in order to obtain the first opening of same cap 2.
  • the safeguard-strip 4 may be of the type that is pulled away manually by pulling on a tongue-shaped part thereof, or it may be detachable along the break line 5, shown in the figure, by unthreading of the cap 2.
  • the cap 2 has at its upper part a knurled rim 6 and is provided, just above the break line 5, with a rib 7 defining a lower shoulder 8.
  • a second cap 9 substantially cylindrical in shape, a lower edge 10 of which is bent inwardly in such a manner as to contract diametrally to define a bearing surface that fits underneath the shoulder 8 of rib 7. In/this way, once the outer cap 9 has been fitted.in place by pressing it down, the cap 9 cannot be withdrawn neither by itself nor by pulling action exerted thereon.
  • a second knurled region 12 designed to engage with the knurled region 6.
  • the knurled regions 6 and 12 are held in an axially spaced apart relationship by fin-shaped formations 13 that project out of the bottom 11 of cap 9 so as to retain the cap 9 in a raised position.
  • the cap 9 is free rotatatble with respect to the inner cap 2 and, thu-s, it is unable to cau se this latter to unthread, whereby the anti-loose action preventing childs from having acces to the bottle contents- such as, for example, a noxious substance-is ensured.
  • the protruding fin-formations 13, that are preferably arranged in a circle on the cap bottom 11, afford spring means which are such that, upon exerting a pressure on the cap 9 in an axial direction,' as shown by arrows F in the drawing , said fin-formations will resiliently deform to cause the knurled region 12 to descend axially to be brought into engagement with the knurled region 6 on the inner cap. Then, by turning the outer cap 9, also the inner cap 2 can be caused to turn therewith, thereby to thread out said cap 2 or thread it down, respectively, as desired.
  • the force that is necessary in order to deform the fin-for mations 13 to bring the two knurled regions into mutual engagement is normally greater than the force that is able of being exerted by, for example, a child, so that any effort by this latter aiming at causing the cap 9 to turn does not involve the risk of the inner cap 2 to be caused to turn therewith and, th-us, to be threaded out.
