Definitions

• the invention relates to a beverage can or an equivalent openable beverage container which comprises a bottom part, a cylindrical side part and an annular cover structure, whereby said side part is attached to the cover structure either via a reducing collar formed at the upper end of the side part or without a reducing collar and said cover structure includes an openable hole for pouring the contents out of the can or for drinking the contents from said can directly.
• the impression-like sections are manufactured to the annular edge directed upwards from the cover structure by making it lower only partially. From this follows that the can cannot be totally emptied, even by turning it upside down. When drinking directly from the can, such lowering of the edge part somewhat directs the pass of the beverage.
• the present invention in a novel way introduces particularly an impression created in the collar part or the top edge of the cylindrical part of a metal beverage can which impression substantially improves the emptying of the can and which creates the drinker’s lower lip a particularly suitable countersurface when drinking directly from the can.
• a new invention which is characterized by forming an inwards-directed impression in a reducing collar or a top edge of the cylindrical part of the beverage can immediately at the point of the hole in the cover structure without substantially damaging the cover structure to form in the beverage can both a pouring spout and a shape improving the drinking event.
• Other embodiments of the invention are described in the dependent claims.
• Fig. 1 shows an inclined view of a beverage can according to the invention.
• Fig. 2 shows a top view of the beverage can according to Fig. 1.
• Fig. 3 shows a side view of the beverage can according to Fig. 1.
• Fig. 4 shows a partial section of the beverage can according to Fig. 3 along line A-A.
• Fig. 1 shows a metal beverage can 1 which comprises a cylindrical side part, a bottom and a cover structure 3.
• the cover structure 3 attaches to the cylindrical part via a reducing collar part 2.
• the can example includes a part of the cover which can be torn off and which forms a tearable part 5 by opening a hole 6.
• Around the planar cover structure 3 circulates an annular attachment part 4 which attaches the cover structure 3 tightly to the collar part 2 and, at the same time, the whole beverage can 1 when closing the can.
• An impression 7 according to the invention has been formed in the collar part 2 at the point of the hole 7 created when opening the beverage can 1.
• the inwards-directed impression 7 can be created in several ways.
• the impression 7 can be provided e.g. by a pressing tool by inserting a counterpart suitable for the purpose inside the can. Then, the cover structure 3 is not yet in its place. It is also preferable to provide a substantially vertical section in the impression 7 which section starts downwards from the edge part 4. In a case, this section can even be a little inwards descending from the vertical direction.
• the impression 7 is providable from the edge part 4 by compression or by aiming a punch to it.
• the edge part 4 does not exactly change its shape, but the impression 7 buckles due to these directions into a desired impression shape. Both the compression motion and the punch must be directed in exactly the correct direction in the solutions according to these methods.
• the metal raw material of the beverage can most often aluminium, endures the shaping according to the invention.
• the edge part 4 and the attachment included in it have held their tightness and substantially their shape in test situations.
• the impression 7 forms a pouring spout or an equivalent passage directing the beverage out of the hole 6 in the beverage can 1 such that the beverage can 1 will easily empty almost perfectly even before it has been turned totally around.
• the impression 7 also directs the drinker’s lower lip suitably under the annular part 4 when drinking directly from the can and, thus, possible dripping of the beverage from the sides is avoided.
• Fig. 2 shows a top view of a conventional beverage can.
• the impression 7 has been formed in the collar part 2 at the point of the hole 6.
• Fig. 3 shows a side view of the same beverage can 1, whereby it is possible to see that the impression starts immediately downwards from the annular part 4.
• Fig. 4 shows a section A-A of the top part of the beverage can 1.
• the section line passes downwards from the centre of the impression 7.
• Fig. 4 shows a vertical section of the impression 7 starting downwards from the edge part 4 which section is in this example substantially vertical. Its direction can obviously vary a bit as either descending inwards or descending slightly outwards.
• the lower edge of the impression 7 again bends smoothly towards the shape of the collar part 2 attaching to it.
• Fig. 4 shows as an example that the section of the impression 7 starting downwards from the edge part 4 has the same distance R from the centre line L of the beverage can 1 as the annular edge part 4. This is an advantageous and preferable embodiment for the impression 7 according to the invention.
• Fig. 4 shows a further embodiment in which the cover structure 3 includes immediately inside the edge part 4 a downwards-directed bracing shape 8. This keeps the cover structure 3 and the edge part 4 braced and thus ensures the firmness of the attachment part in the edge part 4.
• the impression 7 comes on the side part as directed inwards immediately below the annular edge part 4 at the point of the hole 6.
