Definitions

  • the present invention relates to a can for beverages such as colas, sodas, fizzy drinks, beers, teas, energy drinks, and the like.
  • a generic can is constituted by a cylindrical container made of thin sheet metal, for example tinned iron plate or, more recently, aluminum, closed at its opposite ends by a bottom and by a lid made of the same material.
  • the cylindrical wall and the bottom can be formed monolithically by drawing.
  • the lid is usually applied separately by seaming and is provided with a lever-type opening mechanism which cannot be reclosed.
  • the lid is typically provided with an incision with a concave profile, which forms internally a tab.
  • a ring-shaped lever is coupled to the lid proximate to a region in which the incision is interrupted, so as to form substantially a first-order lever; in practice, by lifting one side of the ring, the opposite side pushes the tab toward the inside of the can, opening it, with a cut along the entire profile of the incision.
  • the opening mechanism described above has drawbacks from the hygienic standpoint, since the tab, by opening toward the inside of the can, dips into the drink both during opening and during consumption of the drink.
  • the entire product is often consumed grudgingly at once, or consumed only partially and then thrown away together with the can, with waste and further problems in relation to differentiated waste disposal.
  • a further drawback of traditional cans, when they contain carbonated beverages, is that their exposure to heat sources and/or shaking can cause, upon opening, an uncontrolled outflow of liquid due to overpressure, with spraying, foaming and consequent soiling of the user.
  • the aim of the present invention is to provide a beverage can provided within an opening mechanism that overcomes the hygienic shortcomings described above of known cans, can be closed, is fully recyclable and practical to dispose, and prevents the uncontrolled outflow of the product upon opening.
  • Figure 1 is a perspective view of a can according to the invention in a first operating configuration
  • Figure 2 is a view, similar to Figure 1, showing the can in a second operating configuration
  • Figure 3 is a plan view of the can of Figure 1 ;
  • Figure 4 is a plan view of the can of Figure 2;
  • Figure 5 is an axial sectional view of an upper portion of the can of Figure 1;
  • Figures 6 and 7 are two views, similar to Figure 5, of the can in respective two subsequent opening steps;
  • Figure 7 is a view, similar to Figure 5, showing the can in a first opening step
  • Figure 8 is an enlarged- scale view of a detail of Figure 5;
  • Figure 9 is an enlarged- scale view of a detail of Figure 6;
  • Figures 10 and 11 are two views, similar to Figures 1 and 2, of a can according to an alternative embodiment of the invention.
  • a beverage can 10 comprises a container provided with a cylindrical wall 12 made of thin sheet metal, for example aluminum, which is closed hermetically at its opposite ends by a bottom 14 and by a lid 16, which are made of the same material.
  • the cylindrical wall 12 and the bottom 14 can be formed monolithically by drawing, while the lid 16 is applied separately in a nonremovable manner by seaming along its edge 16a.
  • the lid 16 is provided with an opening mechanism 18 of the lever type.
  • the can 10, except for the opening mechanism 18, can be of a conventional type and therefore its description is not provided in detail herein.
  • the opening mechanism 18 comprises an incision 20 with a closed profile which is provided on the lid 16 and forms internally a tab 22, and a lever 24, which cooperates with the tab 22 for the separation of the latter from the lid 16.
  • the incision 20 is advantageously provided with a bean-shaped profile and can be laser-cut in a per se conventional manner.
  • the lever 24 is coupled at an intermediate point to a pin 26 which rises monolithically from the center of the lid 16.
  • the lever 24 has a pushing end 24a which is arranged proximate to the concave region of the bean- shaped profile of the incision 20 and an opposite annular grip end 24b.
  • a screen 28 made of thin flexible material is interposed between the lid 16 and the pushing end 24a of the lever 24 and is fixed to the tab 22 preferably by means of a welding spot W, and can move between a first position, in which it covers the incision 20, and a second position, in which it exposes the incision 20.
  • the screen 28 is supported so that it can rotate about the axis of the cylindrical wall 12 and more particularly is pivoted to the pin 26.
  • the screen 28 can be made of thin sheet metal, preferably of the same material as the can, for ease in disposal.
  • the screen 28 has an upper wall 28a with a substantially semicircular profile and a side wall 28b which covers the edge 16a of the lid and extends downward from the perimeter of the upper wall 28a so to cover an end portion of the cylindrical wall 12 over an angle of 180°.
  • the lower surface of the upper wall 28a of the screen 28, i.e., the surface that faces the lid 16, is provided with a wedge-shaped protrusion 30 which is superimposed on the incision 20 ( Figures 5 and 8).
  • the wedge-shaped protrusion 30 advantageously has a closed profile which matches with the profile of the incision 20.
  • the wedge-shaped protrusion 30 might have a profile that matches only with a portion of the profile of the incision 20.
  • the wedge-shaped protrusion 30 advantageously has an asymmetric sectional profile, with an inner side that is substantially perpendicular to the lid 16 and an oblique outer side.
  • the wedge-shaped protrusion 30 is preferably covered externally by a gasket 32 made of food-compatible plastic material.
  • the tab 22 has a stiffening ridge 33 which is extended proximate to the incision 20.
  • the lower edge 28c and the opposite longitudinal edges 28d of the screen 28 are advantageously rounded for scratch prevention.
  • the user rotates the screen 28 through 180° about the pin 26, as shown in Figures 2, 4 and 7.
  • the screen 28 carries with it the tab 22, which is welded thereto, thus exposing the opening 0 through which the product can be consumed.
  • a raised portion can be provided on the screen 28 which is adapted to engage alternately one of two recesses (not shown) provided in diametrically opposite positions on the cylindrical wall 12 or on the lid 16 of the can, or other equivalent solutions.
  • the outer surface of the tab 22 never makes contact with the product, with evident advantages from the hygienic standpoint. Furthermore, the screen 28 protects the lid 16 against contaminations in the region of the opening 0, whether the user rests his lips, with further advantages in terms of hygiene.
  • the can is fully recyclable and practical to dispose, since it can be made entirely of the same metallic material.
  • the screen 28 has the additional advantage of protecting the user against uncontrolled outflows of the product upon opening.
  • FIGS 10 and 11 are views of an alternative embodiment of the invention, in which the elements that correspond to the preceding embodiment are identified by the same reference number increased by 100.
  • This alternative embodiment differs from the preceding one merely in that the screen 128, instead of being extended over an angle of 180°, is extended over a broader angle for greater protection.
  • the screen may be provided with dimensions that are slightly larger than the can and with a cambered profile so that the wedge- shaped protrusion, after first opening, applies a slight pressure to the edge of the opening 0 so as to optimize closure.
  • the incision that delimits the tab might have a positioning, dimensions and profile which are different from what has been described. For example, it may have a circular, oval, or other arc-shaped or polygonal profile. Furthermore, the incision might be provided on the internal surface of the lid or two mutually opposite incisions might be provided on respective opposite faces of the lid.
  • the lever may have a shape and dimensions that are different from the ones described and illustrated, for example, it may have a profile shaped like a ring, an oval or a droplet.
  • the lever might even not be necessary and the can might be opened simply by pressing with the thumb on the tab.
  • the side wall of the screen might have a height that is different from what is shown, for example it might cover only the edge of the can or, depending on the circumstances, might even be absent.
