Definitions

  • the present invention refers to a composite closure cap provided with a tampering evidencing band, and of the snap type, i.e. that can be opened by laterally applying a force to a suitable jut with a finger of a hand, generally the thumb.
  • Composite caps are known, provided with a plastic molded ring or skirt portion and a separate metal cover or panel portion.
  • the ring or skirt portion is joined to a tampering evidencing band by means of breakable bridges, in order to immediately make recognizable any action whatsoever for tampering the packing to which such a cap has been applied, even before the real opening of the packing has taken place.
  • the ring or skirt portion is provided with a threading, in order to thraed fasten the composite cap to the container, and the opening of the packing is carried out by unscrewing the cap with respect to the container.
  • the main object of the present invention is to pro­vide a composite closure cap with evidencing of the tampering, of the snap opening type, for a better opening of the packing to which the same cap is applied.
  • Another object of the present invention is to provide a compos­ite cap with evidencing of the tampering, of the snap type, in which the tampering evidencing band is automatically taken apart from the skirt portion, upon the opening of the packing, and stays around the neck of the container as a proof that the tampering of the packing has been carried out.
  • Still another object of the present invention is to provide a composite cap with evidencing of the tampering, of the snap type, of simple and cheap construction, suitable for a mass production.
  • a composite closure cap in which a metal cover or panel portion is inserted from the top end in a lateral ring or skirt portion, plastic molded and joined, at its opposite end, to a tampering evidencing band by means of breakable bridges, is characterized in that at least one jut, designed to be engaged by hand to open the packing, is provided on the outer surface of the ring portion, and locking means are circumferentially located on the inner surface of said ring portion to cooperate with a bead of the container to keep the packing sealed.
  • the main advantage that is achieved with the composite cap according to the present invention is the opening easiness due to the fact that the sticking of the threads, peculiar of the thread caps, is prevented.
  • Another advantage of the present composite cap lies in the easiness of application to the conteiner, without the need that one is concerned about closure torques or sealing precautions.
  • a composite cap of the snap type comprises a plastic molded lateral ring or skirt portion 10, and a separated metal cover or panel portion 12.
  • the metal cover 12 is generally comprised of a stamped and sheared disk, with a sealing gasket 14, sprayed or of another kind.
  • the gasket 14 can be the usual gasket of sprayed plastisol or a cut disk, fastened to the edge or the whole surface of the cover 12.
  • the metal cover 12 is assembled in the upper portion of the plastic ring 10, in a housing delimited in its upper part by a continuous circumferential bead 16, which radially projects towards the inside of the plasting ring 10.
  • the housing for the metal cover 12 is also delimited in its lower part by a set of four shoulders 18, located at an equal distance along an internal circle on the plastic ring 10 and radially projecting towards the inside of the ring 10.
  • the housing for the metal cover takes up a shape elongated along the vertical cross-section of the figure 1, and in this housing there is inserted from the top end the metal cover 12, which is housed in a loose way so as to be able to carry out a certain translational motion with respect to the plastic ring 10, as it will be better explained in the following.
  • the circumferential edge 20 of the cover 12 is shaped so as to snap in its housing after having passed over the continuous circum­ferential bead 16 upon the assembling of the cap and then it can no longer leave its housing, making the cap handling operations easier.
  • the plastic ring 10 has four projections 22, located at an equal distance along an internal circle on the plastic ring 10, radially projecting towards the inside of the ring 10 and offset and alter­nated in the plan view, with respect to the shoulders 18, as it is better shown in figure 2.
  • the projections 22 on the plastic ring 10 are designed to coop­erate with a corresponding continuous circumferential bead 24 of the container 26 in order to keep the cap fastened to the container so as to sealingly close the packing.
  • the plastic ring 10 ends, at its lower part, in a tampering evidencing band 28, provided with a continuous circumferential tab 30, facing towards the inside of the cap.
  • the continuous circumferen­tial tab 30 has a shape with a V-shaped vertical cross-section with respect to the band 28, as it is better shown in figure 1, and it is designed to engage the bead 24 of the container 26 when the cap is in its position of complete closure of container 26.
  • the tampering evidencing band 28 is connected to the plastic ring 10 by a set of bridges, which remain in place after an inter­rupted weakening groove has been carried out around the whole cir­cumference of the ring 10 of the composite closure cap. Obviuosly, the bridges fasten the band 28 to the plastic ring 10 and are broken upon the opening of the packing.
  • a jut 32 is provided on the outer surface of the plastic ring 10, designed to be engaged by the thumb of the person who desires to open the packing. In fact, by acting on the jut 32, one can cause the projections 22 to jump over the bead 24 and therefore the composite cap to be disengaged from the container.
  • the continuous circumferential tab 30 is resilient enough to bend and then to snap, after having jumped over the bead 24 of the container 26, when the composite cap is applied to the container upon the closure of the packing, but, at the same time, having a continu­ous shape along its whole circumference, it provides the tampering evidencing band 28 with a stiffening feature, which allows it to certainly separate from the plastic ring 10 upon the removal of the cap to open the packing, when the continuous circumferential tab 30 remains locked under the bead 24.
  • the preferred embodiment of the present composite cap has been shown and described, it is obvious that some particulars can be changed to fulfil specific requirements. So, the number and ar­rangement of the shoulders 18 and/or projections 22 and their rele­vant mutual positions can be changed. Furthermore, the jut 32 can be repeated along the external circumference of the plastic ring 10 to provide more than one hold for the action of the thumb.
  • tampering evi­dencing band extends to a lower position with respect to the position shown in the drawing, in order to make the manufacture of the weaken­ing groove easier.
  • the continuous circumferential tab of the tampering evidencing band engages a second bead provided on the neck of the container, below the bead cooperating with the projections of the plastic ring to guarantee the sealing of the packing.
