Definitions

• Can closure can lid and can
• the invention relates to a can closure, in particular for a milk can, according to the preamble of claim 1, a can lid according to claim 14 and a can according to claim 17 with such a can closure or can lid.
• beverage cans are known for beer or caffeinated lemonades, for example, which have a tear-open or press-in closure.
• a mostly triangular wall part is provided in the can lid, which is delimited from the rest of the can lid by a line of weakness and can be torn out by means of a tab or pressed into the beverage can to expose a pouring opening in the can lid.
• press-in or tear-open closures are not used in condensed milk cans, since the pouring openings which are formed would generally be too large. Beyond that would the can fold protruding from the edge of the can lead to the problems described at the beginning even with such a press-in or tear-open closure.
• the invention is therefore based on the object of creating a can closure which, in the case of a condensed milk can, enables clean pouring of condensed milk and prevents contamination by adhering residual condensed milk.
• the object is achieved by a can closure according to claim 1, a can lid according to claim 14 or a corresponding can according to claim 17.
• the invention encompasses the general technical teaching of creating a can closure which consists at least partially of plastic and has a pouring opening which can be opened manually by a user without tools, the pouring opening preferably being spaced apart from the can lid.
• the arrangement of the pouring opening spaced apart from the can lid offers the advantage that clean pouring is possible and contamination of the can lid by residues of the poured out liquid is prevented.
• the manufacture of the can closure according to the invention from plastic offers the advantage that it can be inserted into a cutout in the can lid and thereby seals the cutout.
• the lower part of the can preferably consists of two components that are of different hardness.
• the softer component of the lower part of the can serves as a seal and lies in the assembled state on the edge of the cutout in the can lid.
• the seal preferably lies not only on the edge of the cutout arranged in the can lid, but also surrounds the edge of the cutout, thereby protecting the edge of the cutout from corrosion.
• the can plate is usually covered with a protective lacquer layer before processing. When the cutout is punched out in the can lid, however, this protective lacquer layer is damaged at the edge of the cutout, which can lead to corrosion there.
• corrosion at the edge of the cutout in the can lid is advantageously prevented by the cutting edge being enclosed by the seal of the can closure according to the invention.
• Polyethylene (PE) and polypropylene (PP) are particularly advantageously suitable as the material for the can closure according to the invention, but the invention is not limited to these plastics with regard to the material for the can closure, but can also be realized with other plastics.
• the can closure has a lower closure part and a closure cover, the lower closure part being insertable into a cutout in the can lid and being able to be positively connected to the can lid, while the closure cover is connected to the lower closure part by a hinge and is pivotable from a transport position into a use position.
• a pouring opening is arranged in the bottom part of the closure and the closure lid has means for opening the pouring opening in the use position of the closure lid.
• the closure lid is thus preferably folded onto the bottom closure part, the pouring opening arranged in the bottom closure part being opened automatically.
• the pouring opening in the lower part of the closure is closed by a cover which has at least one predetermined breaking point before being opened for the first time.
• the closure cap then breaks this predetermined breaking point when it is pivoted for the first time from the transport position into the use position, as a result of which the pouring opening in the lower part of the closure is released.
• the predetermined breaking point in the lower part of the closure is preferably broken by means of a piercing rib which is arranged on the underside of the closing lid and presses against the cover of the pouring opening arranged in the lower part of the closure when the closing lid is pivoted out of the transport position into the use position.
• This piercing rib preferably has a bevel on the side facing the joint, the height of the piercing rib decreasing along the bevel toward the joint.
• the cover of the pouring opening arranged in the bottom part of the closure is held in a pivoted position by the bevel of the piercing rib, in which the pouring opening in the bottom part of the closure always remains open.
• the piercing rib provided in the sealing cover preferably serves as a handle for pivoting the sealing cover from the transport position into the use position.
• the lower closure part can have a circumferential, preferably groove-shaped recess, into which the mouth edge of a cutout arranged in the can lid engages in a form-fitting manner.
• the can closure according to the invention preferably has a surface contour on its underside or on the underside of the lower closure part in order to form a positive, intimate connection with a corresponding surface contouring on the can lid during a plastic injection process.
• a surface contouring can consist, for example, of small elevations, depressions or bores which are arranged in the can lid at the edge of the cutout for the lower closure part.
• the closure lid in the can closure according to the invention preferably remains independently in the use position after pivoting from the transport position into the use position.
• This can be achieved, for example, in that the closure cover forms an interference fit with the lower closure part.
• the lower closure part and the closure cover can have latching elements in order to form a latching connection between the lower closure part and the closure cover in the use position of the closure cover, so that the closure cover remains in the use position independently.
• the can closure according to the invention can preferably be closed again after opening for the first time.
• a closure flap can be provided, which is arranged on the closure cover and can be pivoted relative to the closure cover, for example by a joint, such as a film hinge.
• the invention comprises not only the can closure according to the invention described above, but also a correspondingly adapted can lid which has a cutout for receiving the lower closure part and a recess for receiving the closure lid in its transport position.
• the recess for the closure lid is preferably so large that the closure lid does not protrude above the can edge in the mounted position in the transport position.
• Such a design of the can closure and the associated can lid is advantageous because the filled cans can be stacked on top of one another without the can closure increasing the stack height or impairing the stackability.
• a surface contouring is preferably provided on the edge of the cutout for the lower closure part in order to form a positive, intimate connection with a corresponding surface contouring on the lower closure part during a plastic injection molding process.
• a surface contouring can consist, for example, of elevations, depressions or bores which are arranged on the edge of the cutout for the lower closure part.
• the invention also includes a can with such a can lid and / or a can closure according to the invention.
• a can with such a can lid and / or a can closure according to the invention.

• Figure 14 is a perspective view of an alternative embodiment of the can closure according to the invention.
• FIG. 15 shows a cross-sectional view of the can closure from FIG. 14 in the assembled state on a can.
• Figures 1 to 5 show a can closure 1 made of plastic, which essentially consists of a lower closure part 2 and a closure cover 3.
• the lower closure part 2 is connected via a hinge 4 to the closure lid 3, the hinge 4 consisting of a film hinge.
• the lower closure part 2 - as will be explained later - is fastened in a cutout 5 adapted to its shape within a can lid 6 of a can 7.
• the lower closure part 2 has a pouring opening 8 which is provided in the transport state of the can 7 (see FIG. 2) by means of a cover 9 in the form of a piercing surface.
• This cover 9 is connected in its areas delimiting the pouring opening 8 via thin-walled predetermined breaking points 10 to the lower closure part 2, while an area of the cover 9 opposite the pouring opening 8 is designed as a film hinge 11 and acts as a joint after being pierced.
• the closure lid 3 is also provided with a pouring opening 12 which can be closed again by means of a hinged closure flap 13 when the can 7 is in use.
• a piercing rib 14 which extends vertically across the pouring opening 12 and the function of which will be discussed later.
• FIG. 2 shows the can closure 1 integrated in the can lid 6 of the can 7, the cover 9 still being connected to the lower closure part 2.
• the cutout 5 is located in the can lid 6, into which the lower closure part 2 is introduced by means of an injection molding process and is thus held in the can lid 6 in a form-fitting manner. There is the possibility of providing smaller elevations or depressions or small bores on the inner contours of the cutout 5 in order to establish an intimate connection between the lower closure part 2 and the can lid 6.
• the can lid 6 also has a recess 15 which is adapted to the contours of the closure lid 3 and into which the closure lid 3 is introduced when the can 7 is in the transport state. This makes it possible to stack several cans 7 one above the other for transport purposes without the closure 1 having a disruptive effect on the stack height.
• the recess 15 is therefore so deep that the closure lid 3 does not protrude above the edge of the can 7 in the transport position.
• FIG. 5 also shows a circumferential latching edge 17 which is arranged on the lower closure part 2 and which interacts with a likewise circumferential latching receptacle 18 arranged on the closure cover 3.
• the pouring opening 12 in the closure lid 3 is covered by the closure flap 13 which permits reclosure.
• the liquid present in the can 7 can be removed via the pouring opening 8 and the pouring opening 12, the metering of the liquid being able to be influenced by the piercing rib 9.
• the dispensing opening 12 of the closure cover 3 is covered by the closure flap 13.
• This closure flap 13 can also be pivotally connected to the closure cover 3 via a film hinge 19 and latches with the closure cover 3 in the pressed-on state.
• the cover 3 also has a handle-like extension 20 with which the cover 3 can be removed from the lower part 2 again.
• a special feature of this exemplary embodiment is that a slit-shaped depression 21 'is arranged in the lower closure part 2', which is covered on its underside by a cover 22 'before the first opening, the cover Kung 22 'is connected to the lower closure part 2' by predetermined breaking points.
• FIGS. 14 and 15 The exemplary embodiment of a can closure 1 "according to the invention shown in FIGS. 14 and 15 largely corresponds to the exemplary embodiments described above, so that, in order to avoid repetition, reference is made to the above description and the same reference numerals are used below for corresponding components, which are only used to distinguish them are marked by two apostrophes.
• the lower closure part 2 consists of two plastic components which have a different hardness.
• the harder plastic component here forms a seal 25" which, in the assembled state, rests on the edge of the cutout in the can lid and thereby seals the cutout .
• the seal 25 also prevents corrosion at the edge of the cutout of the can lid by the seal 25" enclosing the cutting edge. This is advantageous because punching out the cutout damages the protective lacquer layer on the can plate and thus makes it susceptible to corrosion.
