  • the protector Since the protector must be encircled on the perimeter flange 36, the protector has an annular perimeter envelope, which defines an annular perimeter space suitable for housing inside the perimeter flange 36, where the annular perimeter envelope has an opening at its bottom. Consequently, the first annular surface 34 is also arranged adjacent to the annular perimetral envelope, and below, axially, of the annular perimetral envelope, where the internal diameter of the first annular surface 34 is less than the outer diameter of the annular perimeter space .
  • the longitudinal axis 30 is defined by both the can and the shield itself, as the prote own 'ctor has several elements (Ia first annular surface 34, the side section 3, the lower section 38, etc.) defining said longitudinal axis 30.
  • the can is a beverage can.
  • the lower cylindrical section 38 has a height, measured in the axial direction, less than 20 mm, and preferably less than 10 mm. Effectively, It is important that the protector partially covers the central cylindrical part 28 of the can. On the one hand, it is common for the user to touch the upper end of the central cylindrical part 28 with his lips. On the other hand, the protector is much better mounted on the can if it extends forming said cylindrical lower section 38 than if, on the contrary, it ends directly on the conical surface 32.
  • the perimeter of the seal 5 has a tangent that forms an angle greater than 0 or with the longitudinal axis 30 in at least 50% of its points (i.e., in 50% of its length), most preferably in Io minus 80% of your points. It is particularly advantageous for the tangent to form an angle greater than 30 ° in at least 90% of its points. Indeed, if the seal 5 has these geometries, then the breaking effort is much more progressive, which facilitates its breaking.
  • the seal 5 is torn by applying a force between 2 and 3 Newtons on the lower section 38 cylindrical in a circumferential direction.
  • the normal way to remove the protector is by applying a turning movement to the protector with the hand (as if it were to be unscrewed). This turning movement translates into a pair of forces. It has been observed that if the seal is torn by applying the indicated forces, this amounts to a "normal" effort for an average user. It should be taken into account that an expert in the field is able to modify the design parameters (shape and extension of the microperforate 5, total length of the perimeter of the seal, etc., taking into account the thickness and material of the plastic sheet) of such that the indicated tear forces are reached.
  • the seal 5 is symmetrical, since in this way it can be opened in the same way (and applying the same forces) by a right-handed person and by a left-handed person.
  • the seal 5 has a height, measured axially, which is less than or equal to 75% of the total height of the protector, preferably 65%, measured axially.
  • the upper section 26 has a second grooved annular surface 40, coaxial with the longitudinal axis 30, arranged adjacent to the perimeter flange 36, open at its top and closer to the longitudinal axis 30 than the perimeter flange 36, where the second annular surface 40 has a lower diameter, and the upper section 26 has a flat central surface 10, perpendicular to the longitudinal axis 30 and raised above the lower diameter. The central surface 10 is raised enough to accommodate underneath it a plurality of opening mechanisms of the can.
  • the central surface 10 were curved (for example hemispherical) then the image should be generated by means of a pad printing, which is slower and more expensive to make, and it would be more complex to add a label without it having a propensity to form wrinkles.
  • the upper section 26 has a plurality of prominences 6 that project in the radial direction, facilitating the grip of the protector.
  • These prominences can be of many different types. They can be teeth, such as those shown in Figure 2, but they can adopt many other geometries: different types of teeth with more or less teeth with different inclinations, small prominences or punctual protrusions, even roughnesses more or less pronounced, etc.
  • prominence is understood as any geometry that presents changes in height with respect to the original sheet, so as to achieve an increase in the finger grip. It should be borne in mind that it will be customary for these protectors to be mounted on cans of beverages arranged in refrigerators, so it will be very frequent for their surface to be wet and, consequently, slippery.
  • the second annular surface 40 has a coupling area suitable for accommodating the lower end of the can in a tight manner, thus allowing the stacking of a second can (identical to the can on which the protector is mounted) on the protector.
  • the first annular surface 34 has hemispherical grooves 4 that project inwards, that is, towards the container, that is, towards the longitudinal axis 30.
  • the perimeter flange 36 of the cans is not always exactly the same.
  • the perimeter flange 36 of the cans is not always exactly the same.
  • deviations from the nominal levels (although within a pre-established tolerances) inherent in any industrial process are inevitable.
  • the fact of including these hemispherical grooves 4 allows the protector to be optimally positioned, ensuring a good coupling between the protector and the can.
  • the first annular surface 34 preferably has an inward convex section (towards the container or the longitudinal axis 30) in which said internal radius is arranged.
  • This convex section which can have a semicircular cross section, also serves to improve the coupling between the protector and the can.

Abstract

L'invention concerne une protection pour récipients, hygiénique et réutilisable, pour liquides et/ou solides alimentaires, qui comprend une feuille de matière plastique thermoconformable qui présente une section supérieure (26) ajustée sur le bord supérieur (22) du récipient, et une section latérale (3) qui enveloppe partiellement la partie supérieure (20) du récipient et qui comprend un sceau microperforé. La section supérieure (26) comprend une première surface annulaire (34) cannelée, coaxiale à un axe longitudinal (30), disposée de manière adjacente à un rebord périphérique (36) du récipient, ouverte au niveau de son flanc latéral le plus éloigné de l'axe longitudinal (30), et disposée au-dessous, dans le sens axial, du rebord périphérique (36), de sorte qu'une liaison par encliquetage est établie entre les deux lors du montage de la protection sur la boîte. La section latérale (3) recouvre totalement une surface tronconique (32) supérieure du récipient et s'étend, formant une section inférieure (38) cylindrique, jusqu'à recouvrir partiellement la partie centrale (28) cylindrique du récipient.
