Definitions

  • the present invention relates to a tamper evident closure for a liquid container having a neck that ends with a pourer orifice.
  • Tamper evident closures of the aforementioned kind are described for example in documents EP 1603809 , EP 1636110 , EP 988237 and EP 0829429 .
  • closures comprise a tubular member, which is open downwardly, and a plug member in order to selectively close and open the pourer orifice of the liquid container.
  • the tubular member consists of a top portion and a bottom portion, connected by a frangible portion which breaks at the first opening and provides evidence of the container having been opened.
  • the bottom portion is longitudinally constrained to the container by members that directly engage the container or by intermediate members which are in turn longitudinally constrained to the container.
  • closures provide evidence that an opening of the container has taken place, they are often subject to tampering attempts by fraudsters or counterfeiters, aiming to extract the closure from the container neck without damage (e.g. not breaking the frangible portion), so that the valuable liquid in the container can be removed and substituted with a lower quality liquid, thereafter closing the container again by replacing the unbroken closure, to appear as though the container has never been opened and that the contents are genuine.
  • This type of fraudulent activity has clear implications for consumer health and for the reputation of the bottler of the original content.
  • An object of the present invention is to provide a tamper evident closure, having a simple and inexpensive structure, which is able to highlight an attempt at tampering by way of extraction of the closure from the container on which it is applied.
  • a tamper evident closure 100 for application to a liquid container 1 is shown.
  • the liquid container 1 for example a bottle for spirits, has a neck 2 ending with an aperture or a mouth defining a pourer orifice 3.
  • the closure 100 comprises a tubular member 101, which is open at a bottom end 101a and extends along a longitudinal axial direction X-X between an upper or top end cap-like portion 102 and a lower or bottom end sleeve-like portion 103.
  • the sleeve-like portion 103 has a bottom edge 113 defining the bottom opening of the tubular member 101.
  • the lower edge may be provided with a face forming an angle of between 60° and 120° with the longitudinal axis X-X.
  • a frangible portion 107 connects the cap-like portion 102 with the sleeve-like portion 103.
  • the frangible portion 107 is formed by a circumferential weakened line consisting, for example, of cuts separated circumferentially by breakable links and is configured to break at the first opening, when the cap-like portion 102 is separated from the sleeve-like portion 103, as described below. It will be appreciated that other forms of frangible connection between the cap-like portion 102 and the sleeve-like portion 103 could be used instead.
  • the closure 100 further comprises a plug member 123 configured to close and open the pourer orifice 3 of the liquid container 1.
  • the plug member 123 comprises a lip 120 configured to engage inside the neck 2 of the container 1 and seal it.
  • the plug member 123 together with the cap-like portion 102 of the tubular member 101, form a removable cap 121 of the safety closure, which is removably connectable to the neck 2 of the liquid container 1 in order to open and close the pourer orifice 3.
  • the plug member 123 further comprises a tubular skirt 122 coaxial with the lip 120, both extending longitudinally downwardly from a top end 123a of the plug member 123.
  • the tubular skirt 122 has an internal thread 111 configured to engage with an outer thread 6 of the neck 2 in order to allow opening and closing the container 1 by screwing.
  • the plug member 123 is coupled to the cap-like portion 102 of the tubular member 101 such that gripping and turning the cap-like portion 102 results in turning of the plug member 123 and an axial displacement thereof by virtue of the threaded engagement of the internal thread 111 with the corresponding outer thread 6 on the neck 2.
  • the skirt 122 extends inside and is fixedly secured to the cap-like portion 102.
  • the plug member 123 and the cap-like portion 102 may be integrally formed as a unitary member.
  • the plug member 123 may be formed of plastics of the polyolefin family, such as LDPE.
  • the cap-like portion 102 and the sleeve-like portion 103 may be formed from plastics such as HDPE, PP, ABS, or SB.
  • the cap 121 may be covered by an aluminium shell having a frangible portion in correspondence with the frangible portion 107.
  • the sleeve-like portion 103 of the tubular member 101 is provided with inwardly-directed, circumferentially spaced rotational constraint members 109, configured to engage corresponding circumferentially spaced rotational constraint members 4 projecting outwardly from the neck 2 of the container 1 in order to constrain the tubular member 101 rotationally with respect to the container 1.
  • the torque applied is initially transmitted to the sleeve-like portion 103 through the frangible connection 107, but rotation of the sleeve-like member 103 is prevented by the respective rotational constraint members 4,109.
  • cap-like portion 121 and the sleeve-like portion 103 are initially coupled together via the frangible connection 107, rotation of the cap-like member 102, and therefore the connected plug member 123 is also initially prevented, until the force through the frangible connection 107 is large enough to break that connection. Once the frangible connection 107 has been broken, the cap 121 may be unscrewed from the container 1 to remove the plug member 123 from the pourer orifice 3 and thus to open the pourer orifice 3.
  • the sleeve-like portion 103 of the tubular member 101 is further provided with at least one inwardly radially extending constraint member 110, configured to engage at least one corresponding radially outwardly extending constraint member 5, disposed on the neck of the container 1, in order to constrain the tubular member 101 axially along the longitudinal direction X-X to prevent its removal, especially before the first opening of the closure.
  • the at least one inwardly radially extending constraint member 110 may comprise a series of radially inwardly-projecting members, or may comprise a single, continuous inwardly-projecting lip.
  • the corresponding at least one corresponding radially outwardly extending constraint member 5 may comprise a series of radially outwardly-projecting members, or may comprise a single, continuous outwardly-projecting lip.
  • the longitudinal constraint members 5,110 are intended to keep the tubular member 101 permanently fitted on the neck 2 of the container 1, while it is originally closed, before the first opening, and also to retain the sleeve-like portion 103 in position after an initial opening has taken place.
  • the sleeve-like portion 103 includes a recess or indent 115.
  • the recess 115 is positioned in the sleeve-like portion 103 between the bottom edge 113 and the longitudinal constraint members 110.
  • the recess 115 is blind and is formed in the inner surface of the tubular wall, therefore being invisible from the outside.
  • the lower tubular portion 103 is configured to deform, preferably outwardly, in case of an attempt to extract the tubular member 101 from the neck 2 of the container 1 on which the closure 100 is applied.
  • the deformation is shown in 115a and it is intended to be permanent or, at least, to provide a clear indication of the extraction attempt, therefore deterring further attempts on other liquid containers, for example containers arranged on the same shelf.
  • an attempt to extract the tubular member 101 from the neck 2 of the bottle usually takes place by applying a thrust to the bottom edge 113 of the sleeve-like portion 103. That thrust would have at least an axial component pointing toward the cap-like portion 102.
  • the respective constraint members 5,110 react to that upward thrust with a corresponding downward reaction force pointing toward the bottom end 101 a, by virtue of the respective constraint members 5,110 abutting against one another.
  • the recess 115 being placed between the bottom edge 113 and the constraint members 110, undergoes a compression stress that causes its deformation as shown in 115a.
  • the deformation is an outward buckle of thinner- walled material at the recess 115.
  • This visible deformation may be permanent and /or be accompanied by a visible change in the material, such as a change in colour.
  • the recess 115 is formed as an annular groove which extends around the entire circumference of the tubular member 101, therefore defining an annular weakened portion 115.
  • the weakened groove 115 has wall thickness S2 less than the wall thickness S1, and preferably the ratio of S2 to S1 is less than 0.5 or it will be between 0.2 and 0.8. According to the embodiment shown in figures 1 , 2 and 3 , the weakened groove 115 extends 5 mm axially.
  • a safety closure 200 is shown in isolation of the neck of a container on which it is to be applied, whereas with reference to figure 5 , the same safety closure 200 is shown assembled on a neck 244 of a bottle 245.
  • the closure 200 generally comprises a tubular member 201, a plug member 220 and a valve member 224.
  • the valve member 224 comprises a connecting member 241 that is fixedly secured inside the opening 243 of the neck 244 of the bottle 245 by means of a downwardly-extending annular skirt 242.
  • the connecting member 241 also includes an upwardly-extending annular collar 240 onto which a pourer body 219 is axially secured.
  • the collar 242 defines a valve seat 246 on which rests a valve body 247 that can move axially inside a cavity 248 of the pourer body 219 for opening and closing an aperture 249 defined within the collar 242.
  • the pourer body 219 defines a pourer orifice 218 at its upper end.
  • the tubular member 201 comprises, a cap-like portion 202 and a sleeve-like portion 203, initially connected by a frangible portion 207.
  • the cap-like member 202 includes a top wall 208.
  • the plug member 220 is formed in one piece with the top wall 208 and extends longitudinally from the top wall 208 inside the orifice 218 of the pourer body 219.
  • the cap-like portion 202 of the tubular member 201 is provided with at least one annular projection 228 on its outer surface for engagement with at least one corresponding circumferential groove 229 of a skirt member 230, thereby forming mutually interengaging circumferential features to couple the cap-like portion 202 and the skirt member 230 together axially.
  • the skirt member 230 is also radially connected to the upper tubular portion 203 by means of a plurality of axial indentations 231.
  • the removable cap 221 is used to selectively further open and close the pourer orifice 243 of the container.
  • the disclosed example is also provided with means for preventing an attempt of extraction of the closure 200 from the container 245 on which it is applied.
  • the sleeve-like portion 203 of the tubular member 201 is provided with slots 232 axially extending parallel to the axis X-X of the closure and open at the bottom edge 213.
  • Said slots 232 may be uniformly distributed around the circumference of the lower tubular portion 203 or, as an alternative, they may be grouped in a plurality of slots as shown, for instance, in figure 4 .
  • Said slots 232 in case of an attempt of extracting the safety closure from the neck 244 of the bottle 245, shall give rise to visible evidence of such an attempt through the deformation of the wall of the sleeve-like portion 203 in an analogous manner to that described with reference to the first embodiment of figures 1 , 2 and 3 .
  • the weakened portion 232 has wall thickness S200 less than the wall thickness S201, and preferably the ratio of S200 to S201 is less than 0.5 or it will be between 0.2 and 0.8.
  • the weakened portion 232 extends axially in by 2 mm.
  • the tubular member 301 comprises a sleeve-like portion 303 provided with an annular recess 315, which extends around the entire circumference of the tubular member 301, therefore defining an annular weakened portion 315.
