Definitions

  • the invention relates to an irregular aluminum cup and a method for manufacturing the same.
  • a cylindrical shaped aluminum cups is simple and can only have a same diameter for both the bottom and the mouth.
  • a truncated conical shaped aluminum cup is similar to a cylindrical one, also having a straight cup body though with a bottom diameter smaller than a mouth diameter.
  • cylindrical and truncated conical aluminum cups as well as spin formed trumpet-shaped aluminum cups lies in that they allow print on cup bodies to be freely designed and selected, as printing on straight bodies is not limited by printing processes.
  • the spin formed trumpet-shaped aluminum cup generally has a form with a smaller bottom and a larger mouth, it also has the following obvious disadvantages.
  • reprocessing of an aluminum cup body surface cannot be done through overall printing; instead, small-area processing such as local printing in a smaller range is used.
  • the diameter of the finished product increases all the way up, making it impossible to produce an aluminum cup with a shape having a concave central part or one with a convex central part and a recessed mouth. That is to say, diameters of different parts of an aluminum cup, from the bottom to the mouth, are gradually increased, which is irreversible so as to decrease the diameter.
  • any aluminum cup having recessed central part made from other conventional methods cannot have a convex body part with a diameter larger than that of the bottom.
  • Aluminum cups made through spinning and stamping processes can only have a diameter increased gradually from the bottom to the month, with no concave central part. In this sense, the two conventional processes can only produce simple shaped aluminum cups.
  • the invention provides an irregular cup and a method for manufacturing the same.
  • the irregular cup of the invention can have various shapes and completely maintain an appearance print design thereof.
  • An aspect of the invention provides an irregular aluminum cup, which comprises sequentially from bottom to mouth:
  • cup body with printing patterns on an exterior surface thereof and having one or more concave body parts and one or more convex body parts, with the concave body parts and convex body parts alternately arranged;
  • cup month having an edge curled outwardly and towards the cup body arranged at the top of the cup mouth;
  • cup bottom, the cup body and the cup mouth are of an integral structure.
  • the cup body has printing patterns on the whole exterior surface thereof.
  • the printing patterns have one to nine colors.
  • a diameter of a concave body part is equal to or larger than 70%that of the cup bottom.
  • a diameter a convex body part is smaller than or equal to 1.5 times that of the cup bottom.
  • the cup month is a convex mouth or a concave mouth.
  • the cup body comprises sequentially a concave lower body part and a convex upper body part, and the cup mouth is a concave mouth.
  • the cup bottom, the concave body part, the convex body part, the concave cup mouth and the curled edge are of an integral structure.
  • Another aspect of the invention provides a method for manufacturing the above irregular aluminum cup, the method comprises the following steps:
  • cup body comprising a concave body part and/or a convex body part
  • cup mouth by necking or expanding, multiple times, an expanded or necked upper part of the cup body via a necking process or an expanding process, a cup diameter being decreased or increased each time, and then curling the cup month via a stamping process.
  • the pre-formed cylindrical aluminum cup blank is formed by cold extruding an aluminum block and spraying a protection coating onto an inner wall of the aluminum cup blank via an internal coating machine, and preprinting patterns on an exterior surface of the aluminum cup blank is done via an offset printing press with 1 to 9 colors, the preprinted patterns are scaled or stretched as needed in advance.
  • the forming the concave body part (2) of step b comprises necking the body part through multiple processes by decreasing the cup diameter each time through a multistation flexible necking process; and the forming convex body part (3) of step b comprises expanding the body part through multiple processes by increasing the cup diameter each time through a multistation rigid expanding process.
  • a deformation quantity of the cup diameter in each step is less than or equal to 4 mm.
  • the irregular aluminum cup of and the method for manufacturing the same as provided by the invention have at least one of the following beneficial effects:
  • the aluminum cup may have various shapes. As the necking and expanding may be performed through several stages, the maximum diameter of the cup body may be increased to 1.5 times that of the cup bottom.
  • the cups may have various shapes, depending on different degrees of necking and expanding.
  • Printing on the exterior surface has rich decorative colors, which overcomes the difficulty faced by curved surface printing.
  • the inventive process of the invention performs printing before formation, and the preprinted patterns on the surface of the cups are sufficiently protected during the formation. The problem of the formed curved cup body being difficult to be printed on large area or as a whole in the conventional processes is thereby overcome.
  • the inventive aluminum cup and method for manufacturing the same fits for high-speed automated production, which improves the production efficiency.
  • the related apparatuses are modified accordingly to make it fit for high-speed automated production.
  • the conventional technology which works only on a single machine and has to be realized through multiple stages of production is improved and integrated into a technology suitable for full-automation.
  • the production efficiency is expected to be highly increased compared to the conventional technologies.
  • the product cost is reduced as losses caused by the multiple stages of production of the conventional technology is reduced, with the improvement and integration of the production processes. With the improvement in the production efficiency, the overall production cost is reduced.
  • Figure 1 is a three-dimensional schematic diagram of an irregular aluminum cup according to an embodiment of the invention.
  • Figure 2 schematically illustrates a cross section of a cylindrical aluminum cup blank at step a
  • Figure 3 schematically illustrates a diagram of the aluminum cup blank after a concave cup part is formed at step b;
  • Figure 4 schematically illustrates a diagram of the aluminum cup blank after a concave cup part and a convex cup part are formed at step b;
  • Figure 5 schematically illustrates a diagram of the aluminum cup blank at step c.

  • a cup month 4 having an edge 5 curled outwardly and towards the cup body arranged at the top of the mouth;
  • cup bottom 1, the cup body and the cup mouth 4 are of an integral structure.
  • the cup body has printing patterns on the whole exterior surface thereof, and the printing patterns have one to nine colors.
  • a diameter of a concave body part 2 is equal to or larger than 70%that of the cup bottom 1; and a diameter of a convex body 3 part is smaller than or equal to 1.5 times that of the cup bottom 1.
  • the cup month 4 is a convex mouth or a concave mouth.
  • the cup month is a convex month 4; when the cup body next to the cup month 4 is a convex body part 3, the cup month is a concave month 4.
  • Fig. 1 is a three-dimensional schematic diagram of an irregular aluminum cup according to an embodiment of the invention.
  • the embodiment of the invention provides an irregular aluminum cup, which comprises sequentially from bottom to mouth: a cylindrical cup bottom 1, a concave body part 2, a convex body part 3, and a concave cup month 4, an edge 5 curled outwardly and towards the cup body is arranged at the top of the mouth.
  • the cup bottom 1, the concave body part 2, the convex body part 3, the cup mouth 4 and the curled edge 5 are of an integral structure.
