Definitions

  • This description refers, as its title indicates to an easy-to-open lid, of the type used as a closing element for packaging.
  • quick-opening covers are known, which can be formed of metallic material or plastic material, such as that which is the object of this invention.
  • the easily opened lids made of plastic material, are obtained by molding the material and have a general body whose central area is closed by a laminar portion, provided with a ring, and limited by a thin line of material, which conforms a break line, so that when the ring is pulled, the central laminar portion is released, the central space covered by it being open.
  • This type of covers can be applied to close mouths of reduced dimensions, since if the removable laminar portion had a high surface, with a reduced thickness, obtaining it by molding would be practically impossible and at least excessively expensive.
  • the easy-open lid has been devised, object of this invention that has the particularity of being composed of a body of plastic material, which defines two annular configurations, one outer and one inner, joined by a portion of low thickness, forming a break line, and a laminar body, which is fixed, preferably by ultrasound, on the interior configuration of the original body, closing the central area of it.
  • the exterior configuration of the first body is intended to be immobilized on the mouth of a container, and the interior presents, as usual in this type of lids, a ring, integral to it by means of a returned portion, so that when pulling from the ring the interior configuration and the laminar body integral thereto are separated from the external configuration that remains attached to the container.
  • the lid is composed of an original body to which a laminar body is attached, allows the easily opened lid to have high dimensions, and that when extracting the interior configuration together with the laminar body, that the hole originated in the lid present a surface practically equal to the mouth of the container.
  • the laminar body that originally closes the central area of the container is formed of a transparent plastic material, which allows a visual inspection of the product contained inside the package without opening it, which It is currently impossible, taking into account that the lids to which we refer are applied in metal containers, so this particularity represents an important advantage over the plastic or metallic lids currently known.
  • FIG. 1 shows a plan view of the easy opening lid, which occupies us.
  • FIG. 2 represents an elevational view of the cover, diametrically sectioned by a vertical plane that passes through the area where the ring joins with the inner annular configuration.
  • the easy opening lid, object of this invention is originally composed of an annular body (1) and a laminar body (2).
  • the body (1) defines an outer annular configuration (11), intended to be immobilized on the container, preferably metallic, and internally has a peripheral portion (12), of small thickness, which forms a break line and, by means of which joins with an inner annular configuration (13).
  • This annular configuration (13) inside has one of its sides, and more specifically on the side corresponding to the outer area of the container, a reinforcement (14) from which a ring (15) emerges while on the opposite surface of this annular configuration (13) is fixed, preferably by ultrasound, the periphery of the laminar body (2), responsible for closing the central area of the lid.
  • This sheet body (2) is preferably composed of several layers of transparent plastic material, which allows, after fixing the lid on the container, to visually inspect the product contained inside the container, without opening the opening.

Abstract

Couvercle facile à ouvrir présentant un corps en matière plastique qui définit une configuration annulaire extérieure se prolongeant du côté interne par une partie périphérique de faible épaisseur et solidaire d'une configuration interne annulaire présentant en un point de sa périphérie un renforcement d'où part un anneau; le couvercle présente un second corps se composant d'une feuille transparente en matière plastique et jointe, de préférence au moyen d'ultrasons, à la surface inférieure de la configuration annulaire interne, fermant ainsi l'espace vide interne de cette dernière. Ce couvercle s'utilise de préférence pour se fixer sur l'embouchure de récipients métalliques afin d'en assurer leur fermeture.
