Definitions

  • the object of the present invention is to provide a can model for processed foods or not, for use by food companies or others.
  • Said model has an enhanced construction in order to improve its use and efficiency over existing similar ones.
  • Cans for foods and other uses comprising 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 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 has been developed. It consists of a three-piece can, with cylindrical shape with top and bottom of different diameters, wherein one of the ends goes through an expansion process (increase in diameter or neck-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 with finish 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 form of embodiment of the can solves the presented 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 continous rotating type (cooker cooler) wherein rolling of the can is required.
  • the proposed model also has the advantage of allowing the final user to open the can at any of its end with a conventional can opener, usually at the cleanest end due to the piling up.
  • the object of the present application consists of a can L, made of a welded body (1), which is initially cylindrical and which afterward has one of its edges expanded (neck-out), being said body (1) provided or not with reinforcement rims in its body (2) 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 varnished 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 in a conical shape forming the flange (flap) and subsequently the rims for radial reinforcement of the can (2).
  • 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 an upper (5) and lower (6) end that support the body of the can when it is rolled.
  • Said ends (3, 4) have different diameters, being that the difference between them should be comprised within a range between 2 and 6 mm.
  • Said difference between diameters defines a range A, which as a function of the height C of the can L will provide an angle ⁇ .
  • Said angle ⁇ should be within the range from 0.5 to 2° for the can to roll without rotating around its own axis.
  • the table below shows the ratio between the diameter of the top (3), bottom (4), height C and angle ⁇ in relation to market conventional sizes: Top (3) Bottom (4) Height (C) Angle ⁇ 73 70 83 1,035 73 70 92 0,934 73 70 95 0,905 99 96 118 0,728 127 124 135 0,637 155 152 152 0,565 155 152 178 0,483 155 152 226 0,380
  • the conical 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, such as the cans may be processed in continuous rotating autoclave systems (cooker cooler systems), the cans may be stacked, and, since the cans are expanded cans, less steel is used in their manufacture, thus lowering manufacturing costs and sale price of the metal container.
  • continuous rotating autoclave systems cooker cooler systems
  • the proposed conical can, with said construction may be made in diverse sizes and capacities to meet different needs of users of this kind of packaging.
