Definitions

  • the invention relates to an anti-intrusion device and a closure device comprising the anti-intrusion device.
  • an anti-intrusion device has the function of signalling that a container has been opened for a first time.
  • Various types of anti-intrusion devices are known, predisposed to be used in containers of various nature.
  • the great majority of the anti-intrusion devices of known type comprise a component which on first opening of the container to which it is combined, must necessarily be broken or detached by a further component in a way which is irreversible.
  • the aim of the present invention is to provide a new type of anti-intrusion device which is extremely simple and effective.
  • a further aim of the present invention is to provide a new type of closure device which is extremely simple and effective and which comprises the above-mentioned anti-intrusion device.
  • the anti-intrusion device of the present invention comprises a shaped plug 2, provided with a stalk 3 which exhibits at least a cuttable portion 3a.
  • the device further comprises a seating 4 predisposed for housing the stalk 3 of the shaped plug 2.
  • the seating 4 exhibits two portions 4a, 4b which are slidable with respect to one another between at least a first position, in which the two portions 4a, 4b are aligned to one another and can house the stalk 3, and at least a second position, in which the two portions 4a, 4b are not aligned with one another.
  • the relative sliding between the two portions 4a, 4b of the seating 4 from the first to the second position subjects the stalk 3 to a shear stress which when it goes above a certain intensity cuts the stalk 3 inserted in the seating 4.
  • the cuttable portion 3a of the stalk 3 comprises a gully 5, shaped in such a way as to weaken the stalk 3.
  • the gully 5 completely surrounds the stalk 3 at an intermediate transversal section of the stalk 3 itself.
  • the gully 5 can be shaped for example with a sharp bottom which concentrates the shear stress on a small section of the stalk 3.
  • a through-hole 6 can be afforded through the stalk 3 on the same plane as the gully 5, such that the transversal section of the stalk 3 at that point is further reduced.
  • the stalk 3 is preferably provided with a joint portion 7 which is engageable in a first portion 4a of the seating 4 such that the force required to cause the disengagement of the joint portion 7 is always greater than the force required to cut the cuttable portion 3a of the stalk 3.
  • the joint portion 7 exhibits a wedge shape which tapers in the direction of the end of the stalk 3 and exhibits at least a section of head 7a, a size of which is greater than the transversal section of the stalk 3.
  • the head section 7a is conformed such as to abut against an internal surface of the first portion 4a of the seating 4 such as to prevent extraction of the stalk 3 from the seating 4.
  • the anti-intrusion device of the present invention gives rise to a useful and effective closure device for a container.
  • the closure device comprises a first body 10, associable to a first portion 21 of a container 20, and a second body 11, associable to a second portion 22 of the container 20.
  • the first body 10 and the second body 11 are couplable to one another, preferably such as to define a cylindrical handle 23 for the support of the container 20.
  • the first and the second body 10, 11 are coupled in a closed configuration of the container 20 which, in the embodiment illustrated, is subdivided into two portions 21, 22 hinged to one another.
  • a cursor 12 is mobile with respect to the first body 10 and the second body 11 between at least a closure position in which it constrains the first and second bodies to one another, and at least an open position, in which the first and the second bodies 10, 11 are not constrained to one another.
  • the first and the second bodies 10, 11 can distance from one another such that the first portion 21 and the second portion 22 of the container 20 cannot rotate with respect to one another and the container 20 cannot be opened.
  • the cursor 12 is preferably in the form of a cylindrical sleeve, shaped such as to be able to be arranged about the first and the second body 10, 11.
  • the cursor 12 exhibits a longitudinal opening 12a the size of which is such as to enable passage of the first body 10.
  • the longitudinal opening 12a faces the plane of contact between the first and the second bodies 10, 11.
  • the longitudinal opening 12a faces the first body 10 which can pass through the opening 12a itself.
  • the displacement of the cursor 12 between the closure position and the open position consists in a rotation of about 90°C of the cursor 12 about the longitudinal axis thereof.
  • a first portion 4a of the seating 4 is afforded in the first body 10.
  • a second portion 4b of the seating 4 is afforded through the cursor 12 such that in the closure position of the cursor 12 the two portions 4a, 4b of the seating 4 are aligned to one another, while in the open position of the cursor 12 the two portions 4a, 4b of the seating 4 are not aligned to one another. In this way, by moving the cursor 12 from the closure position to the open position, the second portion 4b of the seating 4 slides with respect to the first portion 4a, causing the cutting of the stalk 3 of the shaped plug.
  • the shaped plug 2 can be provided with a flattened portion 8, preferably curved, predisposed to be positioned in contact with the cursor 12 when the stalk 3 is completely inserted in the seating 4.
  • the flattened portion 8 performs both a function as a reference for the shaped plug 2 with respect to the seating 4 and a function as a support for indicative writing or symbols.
  • the functioning of the opening device is very simple and effective. Starting from an initial configuration in which the container 20 is closed, the cursor 12 is in the closed position and the shaped plug 2 is inserted in the seating 4; at the first opening of the container it is necessary to rotate the cursor 12 from the closed position to the open position.
  • the rotation of the cursor 12 leads to the sliding between the first portion 4a and the second portion 4b of the seating 4.
  • the sliding of the two portions 4a, 4b of the seating 4 subjects the stalk 3 to a shear force located at the cuttable portion 3a. When the cutting force overcomes the resistance of the material, the stalk 3 is cut, enabling the cursor 12 to rotate towards the open position. It is clear, on considering the opening device, that the presence of a shaped plug 2 in intact position and correctly inserted in the seating 4 indicates that the container 20, following the positioning of the shaped plug 2, has not been opened.
