Definitions

  • the invention relates to a method for producing tear-open lids according to the preamble of claim 1. Furthermore, the invention relates to a device for producing tear-open lids according to the preamble of claim 9 and a tear-open lid according to claim 15.
  • Tear-off lids are known, for example from DE-U 298 17 592 or off DE-U 92 03 953 . If the container, which is closed with the tear-off lid, contains a liquid, corrosive product, such as salt water, the bare cut edge of the lid opening can corrode. In the case of a tear-off lid with a so-called retort-curl, the rolling of the area with the cut edge upwards and outwards and the overlap with the tear-off foil provide a certain protection against the influence of the product. The bare or possibly corroded cut edge is also not visible. However, depending on the aggressiveness of the product and the storage time of the filled container, traces of corrosion can still be visible.
  • the invention is based on the object of creating an improved method with which tear-off lids can be produced industrially at a very high rate and at low cost, and in which the number of faulty lids with inadequate cut edge protection practically approaches zero.
  • the rolled-up area includes at least the actual retort curl, which adjoins the area of the cover ring that forms the sealing surface and in particular includes the entire area in which the strip of plastic material is present.
  • heating it is meant that the rolled-up area is brought to a temperature that enables the plastic material to melt, it being not mandatory, but preferred, that the entire rolled-up area is homogeneously brought to the same temperature.
  • the melting of the plastic material does not mean that the entire plastic material of the strip has to be brought to the melting temperature. It can be sufficient if the material layer of the plastic material adjoining the cover material melts in order to ensure the adhesion of the plastic material to the cover ring material.
  • the heating is also not restricted to the rolled-up area, it may be that the entire cover ring is heated, but heating is preferred that is essentially restricted or concentrated to the rolled-up area with the strip of plastic material. Any heat sources can be used for this.
  • the rolled-up area is preferably heated before the tear-off film is sealed onto the cover ring, so that this is a separate work step in the production of the cover.
  • the heating and melting of the plastic material can be carried out separately from the introduction of heat during the sealing of the tear-open film and the influence of the heating of the rolled-up area on the seal can also be avoided.
  • Cooling of the cover ring can also be provided between the heating of the rolled-up area and the sealing, for example by means of an air stream, so as not to influence the seal or the sealing parameters for the sealing of the tear-off film on the cover ring.
  • An inductive heating means is preferably used to heat the rolled-up area. This creates eddy currents in the metallic cover material, which cause it to be heated.
  • the heating can affect the entire lid ring. Provision can be made for the arrangement of the inductive heating means and, if necessary, a concentration of the field lines of the inductive heating by means of pole pieces to generate the eddy currents mainly in the rolled-up area.
  • the inductive heating of the metal material of the cover ring can cause the plastic material to be heated very quickly to the temperature at which the plastic material is melted.
  • Inductive heating means have long been used in the industrial environment for heating workpieces and are known to those skilled in the art and are also commercially available. Alternatively, the heating can also take place with infrared radiation or hot air.
  • a heating means contacting the rolled-up area is preferably provided in the sealing tool so that a direct heat transfer takes place from the heating means to the rolled-up area.
  • the heating of the rolled-up area can be carried out separately from the sealing of the tear-off film on the cover ring, so that the sealing is not influenced in a disruptive manner by the heating of the rolled-up area. It is possible to carry out the heating in two stages both outside the sealing tool, in particular inductively, and also inside the sealing tool.
  • plastic material of the strip in the present case includes that the strip comprises or consists of a polymer or a resin, and that the heating of the rolled-up area takes place at least to the melting temperature of the plastic material of the strip.
  • the rolled-up area is heated to a temperature in the range from 100 ° Celsius to 200 ° Celsius and in particular to a temperature in the range from 140 ° to 180 ° Celsius.
  • the top of the lid blank forming the heat-sealable sealing surface for the tear-off film is or comprises a polypropylene-modified lacquer system, or is a polypropylene laminated coating, or is another coating containing polypropylene, and that the underside of the lid blank has a coating of a can interior lacquer with polyester or acrylic or epoxy or polyvinyl chloride.
  • the named choice of material for the strip made of plastic and the named areas for the heating result in a particularly good connection between the named coatings of the cover blank or cover ring and the plastic strip.
  • a foaming agent can be added to the plastic material of the strip so that when the rolled-up area is heated, foaming occurs which can enlarge the area or the surface of the adhesion.
  • the invention is also based on the object of creating a manufacturing device for tear-open lids, by means of which tear-open lids can be manufactured at high speed and inexpensively, which have practically fault-free protection of the cut edge of the tear-open lid against corrosion.
  • the device is used to heat the rolled-up area and melt the Plastic material of the strip ensures optimal adhesion of the plastic material to both sides of the cover ring can be achieved, both of which adjoin the plastic material of the strip in the rolled-up area.
  • the device achieves a hermetic seal between the rolled-up area and the contents of the container to which the tear-open lid is applied. In this way, the corrosion of the cut edge in the case of tear-off lids which have been produced on a device according to the invention can be reliably avoided.
  • the rolled-up area is usually a retort curl that adjoins the area of the cover ring that forms the sealing surface.
  • the heating that can be achieved with the processing station means that the rolled-up area is brought to a temperature that allows the plastic material to melt, although it is not mandatory, but preferred, that the entire rolled-up area is homogeneous on the same Temperature is brought.
  • the melting of the plastic material does not mean that the entire plastic material of the strip has to be brought to the melting temperature. It can be sufficient if the material layer of the plastic material adjoining the cover material melts in order to ensure the adhesion of the plastic material to the cover ring material.
  • the heating is also not limited to the rolled-up area; it may be that the entire cover ring is heated, but heating is preferred that is essentially concentrated on the rolled-up area. Any heat sources can be used for this.
  • An induction heating means is preferably provided as a heat source in the further processing station. This allows a particularly rapid heating of the cover ring, and in particular of its rolled-up area, to the desired temperature, which is required for melting the strip made of plastic. This means that the high production rate for tear-off lids can also be maintained with the additional processing station.
  • the further processing station can be provided at any point along the conveying path of the device between the processing station which produces the rolled-up area and the sealing station. It can be arranged before or after a turning station of the device. The arrangement in front of the turning station is advantageous because it allows the cover rings to cool down again up to the sealing station.
  • An additional cooling station which cools the cover rings with an air stream, for example, can serve for cooling.
  • the cooling before the sealing station has the advantage that the sealing parameters are not influenced by the previous heating of the cover ring.
  • the further processing station is integrated in the at least one sealing station and has a heating means that contacts the rolled-up area in the sealing tool.
  • the further processing station is preferably integrated in the second sealing station.
  • the further processing station is designed in particular for heating the rolled-up area in the temperature range from 100 ° Celsius to 200 ° Celsius and in particular in the range from 140 ° to 180 ° Celsius. It is also preferred that the application station for applying the band-shaped plastic strip is designed in such a way that a strip with a substantially uniform thickness, in particular a thickness in the range from 0.05 mm to 0.5 mm and in particular with a thickness of approx , 1 mm, can be generated. The small thickness of the strip is advantageous for the rapid reaching of the melting temperature.
  • the invention further relates to a tear-open cover, comprising a circumferential fastening section, a sealing flange with a sealing flange Tear-off film, and a rolled-up area that runs around the sealing flange and laterally delimits the removal opening, the rolled-up edge having a seal made of a plastic, which term means a polymer or a resin, which is made by melting the plastic in the rolled-up area with the top and the underside of the tear-off lid is adhesively connected.
  • a plastic which term means a polymer or a resin, which is made by melting the plastic in the rolled-up area with the top and the underside of the tear-off lid is adhesively connected.
  • FIG. 1 shows a cover blank 1.
  • a stack 12 which contains a large number of such lid blanks, which are individually stacked and processed along the transport path by different processing stations, whereby lid rings are first formed from the lid blanks and these are then processed further to the finished tear-off lid.
  • the cover blanks are, for example, round disks made of coated metal and thus protected against corrosion, for example made of coated tinplate.
  • the coating of the in Figure 1 upper underside is usually different from that in Figure 1 underlying coating of the top of the blanks 1.
  • the conveying device 22 which conveys the lid blanks, the lid rings and the tear-off lid in the manufacturing device 20 along the transport path in the direction of the arrow A from one processing station to the next processing station, is formed in particular by two toothed belts running in parallel, on which receptacles for the lid blanks or Cover rings are provided, as will be apparent to those skilled in the art WO 2006/017953 known. This is also not explained further here.
  • the blank to be processed is lifted off the conveyor 22 and processed by the respective processing station and returned to the conveyor 22. This is indicated with arrows pointing up and down at the processing stations.
  • the drive of the machining stations is indicated below the conveyor. This is used to raise and lower the blanks and cover rings and to carry out the respective processing steps.
  • a cover ring 2 is first formed from the cover blank 1 by cutting out a central part 30 of the blank and disposing of it as waste. This forms the removal opening of the tear-open cover, which is closed with the tear-off film in a later manufacturing step.
  • a sealing flange 7 remains adjacent to the removal opening 15.
  • the metal material lies bare at the cut edge 31 or the sheet metal of the cover ring 2 is no longer protected there by the coating or coatings.
  • the edge of the removal opening is pulled upwards to form a collar 4 and this collar is rolled in a further processing station 25, so that a so-called retort curl 5 is formed.
  • the shape of the curl or the retort curl can be different.
  • the curling which forms the edge of the removal opening ensures that the user of the can is protected from the sharp-edged cut edge 31 when removing the contents of the can.
  • the turning station 26 follows, which turns the cover rings, so that during further processing the sealing flange 7 is at the top after the turning station in the conveyor device 22 and in the processing stations.
  • the tear-off film 8 is then sealed onto the sealing flange, which can be done in two stages with a first sealing station or pre-sealing station 27 and a second sealing station or a main sealing station 28.
  • the sealing process is also known to the person skilled in the art and is not explained further here. Further processing stations can follow in which the sealing film is embossed, the tear-off tab is positioned and the seal is tested for leaks. This is also known to the person skilled in the art and is not explained further here.
  • finished tear-off covers 10 ( Figure 5 ) output whose removal opening 15 is spanned by a tear-off film 8 which is sealed on the sealing flange 7.
  • the edge of the removal opening 15 is by a (in the position of the lid according to Figure 5 ) retort-curl 5 bent upwards and outwards.
  • the finished tear-off lid 10 can be attached to a can jacket (shown in FIG Figure 5 is only indicated with a wall part 11) are attached and thus closes the box. This takes place in the bottling plant in which the can has been filled with a product.
  • the filled can can be opened later by tearing the tear-off film away from the lid ring by means of its tear-off tab 18, with the result that the removal opening 15 is open.
  • Figures 6 and 7 show a cover ring in which the processing step of drawing the edge of the removal opening to form the collar 4 has already taken place. This took place in the processing station 24.
  • an inward curvature has been produced at the upper end 34 of the collar 4, which facilitates the subsequent curling to form the retort curl.
  • a plastic strip 32 has also been applied to the inside 40 of the collar 4 in one work step. This plastic layer is applied in a separate processing station 29, which is arranged between the drawing station 24 and the rolling station 25.
  • the band-shaped strip 32 made of the plastic material forms a seal for the cut edge 31 when it is rolled up, which is shown below.
  • the strip 32 consists of a plastic, which term here means a polymer or resin. Such plastics are commercially available and in particular also commercially available in qualities that reliably withstand the sterilization temperature during the sterilization of the filled container and thus do not melt again at the sterilization temperature, so that the seal formed by the strip is retained during the sterilization.
  • the strip is preferably of uniform thickness over the entire height of the band. It is provided as a thin plastic strip, which preferably has a thickness d in the range from 0.05 millimeters to 0.2 millimeters, preferably a thickness of approximately 0.1 millimeters.
  • the height H of the strip can be, for example, 1 to 3 mm.
  • the application is preferably carried out on the basis of the expert WO 2015/164986 A1 known way by spraying molten, liquid plastic material, with a relative movement of the nozzle and cover ring.
  • the cover ring is moved in a rotating manner in the processing station 29 and the inside 40 of the collar 4 is moved past the outlet opening of a spray nozzle which is statically arranged during application and from which the plastic emerges.
  • the cover ring is thus raised at the processing station 29, set in rotation and the application is activated when the cover ring has reached the correct position in relation to the outlet opening.
  • the cover ring After at least one full revolution, when a continuous band or such a strip is formed on the inside, the cover ring is moved back down to the conveyor, whereby the rotation is stopped so that the cover ring is placed back on the receptacles of the conveyor can. Then it is conveyed to the roll-in station 25.
  • the plastic of the band 32 cools down as soon as it is applied to the cover ring and solidifies so that the plastic does not flow during further conveyance and the band is stable in the form shown.
  • a coolant for example in the form of a fan, can be provided in the application station or processing station 29.
  • the strip 32 can also be applied to the cover ring in other ways. So it is possible to have a insert prefabricated strips of plastic material in the collar of the cover ring. This can take place in a separate processing station or when pulling the collar in station 24 or when rolling in the collar in station 25. In these cases the station 29 shown would be omitted.
  • the strip 32 is positioned on the inside 40 of the collar 4 that it is closer to the plane of the sealing flange 7 than to the cutting edge 31.
  • the positioning and dimensioning of the strip is approximately such that the strip 32 is the lower third of the Collar 4 to about the lower half of the collar 4 covered.
  • a greater height H of the strip is possible, but then the cost of material for the plastic used increases without this being necessary for further processing or for protecting the cut edge. In practice, the height H will be approx. 1 mm to 3 mm.
  • Lid ring provided with the plastic strip is provided with a retort curl 5 in the processing station 25 in a known manner.
  • This station 25 works with the rolling tools known for this, so that this does not have to be explained in detail here, since this is known to the person skilled in the art.
  • a modification which is obvious to a person skilled in the art may arise in the case of the tools if the collar 4 has already been pre-bent at its upper edge 34 for curling, which is preferred.
  • the Figures 8 and 9 show the cover ring after the turning station 26, that during the formation of the retort curl 5 the strip 32 forms a seal which prevents the entry of liquid into the interior of the retort curl.
  • the manufacturing device 20 for the tear-off lid comprises the processing station 29 for applying the tape 32 to the lid ring and the processing station 25 for rolling in the collar 4.
  • the rolled edge area is heated in order to melt the strip 32 at least in the contact area with the metal of the lid or the coatings on it.
  • the rolled-up edge area includes at least the retort-curl 5, as it is for example in Figure 9 can be seen and in particular the entire part of the tear-open cover covered by the strip 32.
  • a processing station 35 is provided in front of the turning station 26, in which processing station 35 the rolled-up area is heated. This can be done in such a way that the cover is also lifted off the conveying means 22 at this processing station 35, followed by heating in the processing station and then placing on the conveying means.
  • the cover ring or its rolled-up area can, however, also be heated in the processing station while it is on the conveying means 22, that is to say without being lifted off the conveying means.

  • the sealing tool has a special heating means 38, which directly contacts the rolled-up area and in particular the retort-curl 5 in order to bring the heat of the heating means 38 into the rolled-up area to heat the same and to melt the strip 32.
  • the thermal energy for the heating means 38 is provided by the heating elements 39, which also serve to heat the lower sealing tool below the sealing flange 7.
  • These heating elements 39 which are electrically heated, are in direct connection with the sealing tool and are in heat flow connection with the heating means 38 via a heat transfer layer 42.
  • This is a preferred example, but it is obvious to a person skilled in the art that it generates heat for the heating means 38 can also be used in other ways for the rolled-up area.
  • a tear-open cover 10 with a rolled-up area of the removal opening 15 is thus formed so that before the rolled-up cover is formed Area a plastic strip 32 is applied to the collar of the cover ring. After the rolled-up area has been formed, the plastic strip is melted in order to ensure good adhesion of the plastic to the top and bottom of the tear-open cover in the rolled-up area. This results in a practically hermetic sealing of the cut edge 31 of the tear-open cover in a cost-effective manner and with the possibility of production at high rates.
