Definitions
- the invention relates to a method for producing a filled, closed, sterilized, from at least one Fuselage body and at least one closure part existing Container that can be opened without the use of tools can.
- Containers in general and packaging in particular in particular (although in used in a broad sense the term "container” will be) without the use of tools such as e.g. knives, can openers etc., can be opened, i.e. so-called easy-open systems, have been in recent years the significant simplification of handling by the Consumers are becoming increasingly important.
- the invention is therefore based on the object of the generic type To further develop methods in that the Disadvantages of the prior art can be avoided and without the risk of unintentional destruction of the filled Container during the sterilization process an easy-open system is made available.
- this object is achieved with a generic Process solved in that after filling with the intended Container contents, sterilization-proof closure and Sterilization of the container at temperatures leading to preservation of the container contents are sufficient, a weakening the connection between predetermined or through this process step defined container parts in the manner that a separation of these container parts without the help of Tool can be done.
- the base material of the Container different material is an adhesive material.
- the weakening or severing takes place of the fuselage body in an area adjacent to the closure part.
- the body of the container in the area the weakening or severing of the container wall on its inside with a substantially complete one sealing material encircling the circumference of the fuselage body is deposited.
- the Fuselage body in the area of the deposit with sealing material with at least two, essentially horizontal Beads is provided.
- the weakening takes place or severing the trunk body on one of the sikken.
- At least three beads are provided and the weakening or The fuselage body is severed on the central bead.
- the deposited sealing Material down to the intermediate area between the Fuselage body and the closure part extends into it.
- the weakening is provided or severing the closure part in the area of a Folding of the closure part takes place.
- the invention proposes that the edge region of the closure part with the outside of the outer surface of the trunk body of the Container is not releasably connected.
- the invention proposes that both in the trunk body and an interlocking thread in the closure part for opening of the container is provided.
- the interlocking thread above the weakening or Cut line arranged.
- the invention proposes that the interlocking Thread below the weakening or severing line is arranged.
- the weakening or The container wall is cut using laser technology.
- the weakening or severing the container wall on a substantially horizontal circumferential line can be provided that the weakening or severing the container wall on a substantially horizontal circumferential line.
- connection is weakened between the fuselage body and the closure part.
- the invention proposes that one essentially fully circumferential deformation in the area of the fold, the trunk body and locking part connects, takes place.
- the deformation such that the angle of the plane in which the radially at farthest outer contact surfaces of the fuselage body and Closure part run, is changed so that a separation between the fuselage body and the closure part without the aid of Tool is made possible.
- the plane in which the radial runs outermost fuselage body contact surfaces and the closure part run essentially after the deformation parallel to the wall of the fuselage body.
- the filled container before closing the same with the closure part with a Foil made of heat-sealable lacquered aluminum, plastic or a corresponding composite material is sealed.
- closure part any type of container closure is meant to be dependent on the shape of the container and the type of filling and the Closure of the container.
- closure part therefore, for example, the lid body or the base part be, for the sake of illustration largely on the lid body is referred to.
- the base material for example, the trunk body of the Metal box, fully rotating in an upstream step be severed, whereupon the two parts of the container by means of a material different from the base material, such as or a sterilization-resistant adhesive material become.
- a material different from the base material such as or a sterilization-resistant adhesive material become.
- the inventive method is only required in the intended area of the inner wall of the fuselage body a sealing material, for example a strip of the corresponding Plastic material to be applied after the final Weakening or severing of the trunk body in it Area continues for a secure sterile closure of the container.
- the weakening or severing the lid body such a deposit is required of the fuselage body with a sealing material
- the said weakening in the area of the fold of the lid body takes place and more precisely affects only the part of the fold, which is provided by the lid body.
- the security the sterile seal of the packaging is in this Fall through that usually between that through the trunk body on the one hand and the cover body on the other provided sealing component ensures the sealant introduced, even after the weakening according to the invention or severing in the area of the fold of the lid body still remains functional and for a safe sterile Closure provides.
- a sealing material e.g. a strip of appropriate plastic material for covering attached to the line of weakness or severing become.
- lid body placed or fastened across the trunk body is so that the inside of the lid body with the outside of the fuselage part is at least partially in contact and the edge area of the lid body with said outside is not detachable, for example by soldering.
- the weakening or severing of the container wall can be done in any way, in particular to a circumferential mechanical cutting or the Application of laser technology is intended.
- To prevent corrosion in the Avoiding the cutting area is preferably provided Area of final surface corrosion treatment to undergo.
- a at least partially deformable coating from, for example a copolymer of polypropylene and polyethylene based on the inside of the fuselage body and / or the lid body of the Container is provided when closing the container with the lid body compressed and under this pressure and if necessary deformed additional heat and thus forms another sealing closure of the interior of the container.
- Internal coating has the advantage that - if the lid body after opening the can and partially emptying it again should be - a closer seal is possible.
- a weakening of the connection between the fuselage body and the closure part, such as the cover part is provided.
- This weakening preferably takes place in that essentially fully circumferential deformation takes place in the region of the fold which connects the body of the body and the closure part.
- This deformation must be carried out in such a way that there is still a sufficiently firm closure between the body of the body and the closure part, which, however, no longer has to have the strength to withstand the internal pressures during sterilization, since the corresponding process step according to the invention is only provided after sterilization.
- the can body is 10 and the one on it crimped lid designated 20.
- a first embodiment is in the upper area the can body 10 just below the lid 20, the inner wall of the can body with a circumferential strip 30 sealing material, preferably made of plastic.
- a weakening or severing of the can body shown. The weakening at this point must be sufficient be that with mutual rotation of the upper section 10 'of the can body together with the lid 20 against the lower part 10 "of the can body this over the Detach the entire circumference of the can.
- the deposited plastic strip 30 can with this shear movement either tearing open in the area of weakening or Cutting line of the can body especially if at a complete cut through the plastic strips has already been "scratched", or a detachment from the Boundary layer 30 'between the can body 10 and the plastic strip 30 done.
- detachment occurs at interface 30 ', it should preferably in the area below the weakening or Cut line, because in this case a reclosability the opened cans is simplified. To This purpose could be thought of inside the can deposited plastic strips in the upper area more fix as in the lower area.
- FIG. 2 Another embodiment of the present invention is shown in Fig. 2, in which the deposit with the plastic strip 30 in the area of two essentially horizontally extending beads 16 and 17 is done.
- the weakening or In this embodiment, the can body is severed at a point 12 between the two beads.
- the guidance of the cutting tool can Attach the weakening or severing line easily adjusted or guided.
- 3 are a total of three in horizontal beads running at substantially the same distance 16, 17, 18 provided with a plastic strip 30, the weakening or severing of the base body on the middle bead 17. Because in this area deposited plastic material has its greatest thickness, there is a particularly high degree of certainty that if severed the base body does not include the deposited plastic material severed or damaged too much to another To ensure secure closure of the can in this area.
- Fig. 4 is also the plastic material 30 as far up on the inside of the can or the Cover 20 pulled down so far that the plastic material what protrudes into the area between the can body and the lid a particularly firm connection of the plastic material in the Guaranteed upper area 10 'of the can body and thus greater certainty that separation at the boundary layer 30 'below the weakening or severing line.
- a fold is formed, both the edge area of lid 20 as well as of can body 10 involved is.
- Sealing material is located between the two components 15.
- the weakening or severing of the invention Container in this case the can, takes place in the area of the fold at 11, the weakening or severing the component of the fold supplied by cover 20 relates. Not least due to the presence of sealing material 15 it is ensured that after the weakening or Cutting through the base material of the can lid in the rebate area the can is still tightly closed.
- Fig. 7 which with respect the location of the weakening or severing of the base material 6 may be similar be provided that cover 20 and can body 10 with a Interlock thread 40. In this case the Weakening or severing of the can body above the highest point of the thread.
- FIG Cover 20 In another embodiment shown in FIG Cover 20 is pushed over the upper region 10 'of the can body and closes it, the seat of the lid on the Can body is secured by thread 40. In the contact area between the upper area 20 'of the lid and the upper one Area 10 'of the can body contains sealing material 15 and ensures the sterilization-proof closure of the can.
- the lower area 20 '' of the lid is soldered to the socket body 10 and is therefore not detachable connected.
- the point 11 of weakening or severing the can-like packaging is in the present case in lower area 20 '' of the cover. Similar to that in Fig. 7 embodiment shown is plastic material 30 so far not required for the sealing material 15 to seal Closure after applying the weakening according to the invention or cutting through the base material of the can-like packaging guaranteed.
- FIG. 9 shows an overall schematic view of the embodiment 5, with instead of one - as previously described - essentially horizontal circumferential weakening or cut line a wavy line provided so that over certain areas of the can circumference a slope and thus a corresponding stroke when opening the can is created, which means the effort required to open the Can can be reduced.
- FIG. 10 shows an overall schematic view of the embodiment 7 consisting of can body 10 and lid 20, with cover 20 and can body 10 with a thread 40 mesh.
- this provides Thread for the reliable reclosability of the can-like packaging required closing force, whereas the far greater mechanical stress as it during of the sterilization process occurs, picked up by the fold after sterilization without the Negatively affect the functionality of the packaging, can be weakened or severed according to the invention.
- the can preferably have a gripping bead in the central region of the lid 20 25 may be provided, as indicated in the drawing.
- FIG 11 shows a schematic overall view of FIG 8 shows a partial cross-sectional view of a can-like one Packaging, here also the packaging from the can body 10 and cover 20 there. Similar to that shown in FIG. 7
- the concept is also thread in this embodiment 40 responsible for absorbing the locking force.
- force is given by the lower area 20 '' of the lid soldered to the can body 10 edge area guaranteed.
- the embodiment presented here lends itself to the can body provided with lid 20 10, which is not yet closed at the bottom, by the Bottom opening of can body 10 to fill and after completion of filling the can body with a bottom conventional way to close. Only after that Packaging and its contents have been sterilized, is according to the invention a weakening or severing of the base material of the Cover 20 brought about, said point of weakening or cutting below the lowest point of Thread 40 is.
- Fig. 12 is the upper edge area of a container, for example a can.
- the rest of those of Fig. 6 is both on the inside of the Lid body 20 as well as on the inside of the fuselage body 10 applied coating 50.
- This coating which preferably made of a polypropylene homopolymer or copolymer exists when the trunk body is closed by the Lid body compressed and under this pressure and possibly additional heat deformed, which is what is indicated in the drawing Bead 52 leads so that there is a better seal in this area results in addition to the outer seal the weakening or severing and the between Lid body and fuselage body introduced in the rebate area Sealing material 15 a further security for the tight closure the can yields.
- FIG. 13 of the drawing shows a further embodiment, in which the fuselage body 10 with a (sealable) Foil 70 made of, for example, a composite material made of aluminum and plastic is closed before the further closure done with the lid body.
- the closure with the sealable film is done by sealing in the edge area of the Fuselage body 10, for example, by sealing on the inside of the fuselage body in the specified area A.
- FIG. 14 shows two different possibilities of deformation in the fold area 80 of a sterilization-proof sealed can.
- the illustration on the left shows the typical fold closure a can that is suitable for sterilization to withstand occurring internal pressures, on the other hand What is certain is that this closure can be opened without assistance of tools is not possible.
- a deformation tool in the upper area of the fold area 80 is, according to the invention, after sterilization made a deformation in this fold area 80, such as them in two alternatives in the middle and right representation 14. This essentially takes place pressing the upper area of the fold area 80 inward, whereby essentially the flanging 81 at the top of the Can body 10 deformed, i.e. pressed more or less flat becomes. This will engage between the flare 81 of the can body 10 and the flanging 82 of the lid 20 weakened to such an extent that without the use of tools, i.e. by simply unscrewing and opening the can can. At the same time, the weakening of the connection between can body 10 and lid 20 not so extensive that accidental opening of the can during storage and transport is to be feared.
