Definitions

  • the object of the present application is to provide a can for processed or non-processed foods, for use by food companies or others. Said can has an enhanced construction in order to improve its use and efficiency over existing similar ones.
  • Cans for foods and other uses generally comprise three pieces with welded cylindrical bodies, seamed by a mechanical process at their upper ends by a top and at their lower ends by a bottom of the same shape, are already known in the state of the art. Said cans may or may not be provided with rims in the cylindrical body to reinforce it, allowing the use of thin sheets.
  • the present invention relates to a three-piece can, having a cylindrical shape with a top and a bottom of different diameters.
  • One of the ends undergoes an expansion process (increase in diameter or necking-out), but within certain limits not to compromise its rolling on flat guides and surfaces minimizing friction of the external part of the cylindrical body having a coating or artwork while rolling.
  • Said can may also be piled up, since it is provided with top and bottom of different diameters which fit in when stacked.
  • This embodiment of the can solves the above inconveniences, since the expanded cylindrical shape of the assembly allows for appropriate flexibility during the use, meeting various forms of use of stackable cans with the artwork already printed on the cylindrical body, especially in automatic thermal processing equipment of continuous rotating type (cooker cooler) where rolling of the can is required.
  • the can according to the invention also has the advantage of allowing the final user to open the can at either end with a conventional can opener, usually at the cleanest end due to stacking.
  • FIG. 1 is a partial cross section of a conventional three-piece can with top and bottom of same diameter
  • FIG. 2 is a partial cross section of a conventional three-piece can with top and bottom of different diameters and reduced diameter at one of the ends of the tube (necking);
  • FIG. 3 is a partial cross section of a can according to the present invention, provided with an expansion of its upper part (necked out);
  • FIG. 4 is a view of a stack of cans of the present invention.
  • FIG. 5 is a detailed view of a can rolling over a flat surface, showing the lack of contact between the body of the can (tube) and the surface due to the presence of a free space (gap).
  • the present invention is directed to a can L, made of a welded body 1 , which is initially cylindrical and which subsequently has one of its edges expanded (necked-out), the body 1 is optionally provided with reinforcement ribs 2 in its body when the metal sheet to form the body 1 is thin.
  • the can L is preferably made of tinplate and/or chrome-plated steel, appropriately smoothed and printed with the artwork defined by the user.
  • the cylindrical body 1 is formed by the conventional process of plate cutting, formation of the body, calendering and welding. Initially, the body 1 is built with the base dimension (smaller), the tube is expanded at one of its ends (necked-out), the flange (flap) is formed and subsequently the ribs 2 for radial reinforcement of the can L.
  • Said can L has an upper closing consisting of a conventional or easy-to-open top 3 and a conventional or easy-to-open bottom 4 .
  • Said top 3 or bottom 4 is seamed at one of the ends according to the needs of the user. When seamed, said top 3 and bottom 4 form upper 5 and lower 6 ends that support the body of the can when it is rolled.
  • Said ends 3 , 4 have different diameters, wherein the difference between them should be comprised within a range between 2 and 6 mm.
  • Said difference between diameters defines a range where the difference cannot be higher than 4 mm to allow the can to roll around its axis without deviation and, at the same time, allow it to be piled up.
  • the table below shows the ratio between the diameter of the top 3 and bottom 4 :
  • the can is sent to the user with one of the ends (larger or smaller) already seamed according to the client's requirements and/or tooling in the client's plant to close the cans after product filling.
  • the present invention presents several advantages to the conventional models, since the cans may be processed in continuous rotating autoclave systems (cooker cooler systems), and the cans may be stacked.
  • the proposed can with said construction, may be made in diverse sizes and capacities to meet different needs of users of this kind of packaging.
