Description

Field of invention

[0001] The invention relates to a packaging made of sheet metal material with a tear-off foil lid, a material set for forming such packaging, a method for producing the material set and a method for producing filled such packaging according to the preambles of the independent claims. background

[0002] Packaging with peel-off lids (so-called peel-off ends or POE) is known from many different areas, especially as food packaging.

[0003] In their simplest form, such packaging consists of two parts: a single-piece container and a tear-off film that seals the container's filling and dispensing opening. However, these two-part packages with tear-off film lids have the disadvantage that the surfaces intended for sealing with the tear-off film can become contaminated during filling, potentially leading to a faulty seal and thus a leak. To minimize this risk, the filled container must be moved relatively slowly until the tear-off film is sealed, which significantly limits the production speed of such packaging. There is also the inherent risk that the contents will be contaminated during the sealing process and / or altered by temperature fluctuations.

[0004] To avoid the disadvantages of two-part packaging described above, three- and four-part packaging with tear-off foil lids was developed, in which the container is filled from the end of the container that is opposite the tear-off foil lid, and this end is then closed with a separate metal lid.

[0005] These three- and four-part packages feature a frame formed by a rolled and longitudinally welded sheet metal ring, which forms the container walls and is sealed at one end with the tear-off foil lid and at the other end with the aforementioned sheet metal lid. Depending on whether it is a three-part or four-part package, the tear-off foil is sealed directly onto a sealing flange formed by the frame (three-part) or onto a separate sheet metal ring that is connected to the end of the frame (four-part).

[0006] The disadvantage of the three-part versions is that the sealing flange is radially traversed by a weld seam, which is suboptimal from a process engineering perspective and can lead to sealing problems.

[0007] The disadvantage of the four-part versions is that an additional component (sheet metal ring with sealing flange) must be provided and processed, leading to higher material and production costs and additional waste during manufacturing.

[0008] The aforementioned three-part and four-part packaging also has the disadvantage that the metal lid for the packaging base must be provided and managed separately, which leads to significantly higher material and production costs and additional waste during manufacturing compared to two-part packaging.

[0009] From WO 2021 / 176112 A1, a three-part packaging is known, consisting of a deep-drawn cup which, after filling, is sealed with a two-part lid consisting of a metal ring whose central opening is covered by a sealing film. This packaging variant has the disadvantage that handling such two-part lids is problematic and consequently limits the production speed.

[0010] From CH 530 310 A, a can with a frame is known which has a crimped lid ring at its upper end, the dispensing opening of which is sealed with a tear-off foil. The frame is connected at its lower end by crimping to a sheet metal lid, which forms the packaging base, or it is formed in one piece by deep drawing with a can base molded onto it. Description of the invention

[0011] The task therefore is to provide packaging with a tear-off foil lid that does not have, or at least partially avoids, the aforementioned disadvantages of the prior art.

[0012] This problem is solved by the subject matter of the independent patent claims.

[0013] According to these, a first aspect of the invention relates to a packaging made of sheet metal with a tear-off foil lid. The packaging comprises a seamless frame produced by deep drawing, which forms a packaging wall enclosing the interior of the packaging. The frame has a first and a second end and forms a dispensing opening at its first end, surrounded by a sealing flange, which is closed with a tear-off foil lid glued or sealed onto the sealing flange. The second end of the frame is connected by crimping to a sheet metal lid, which forms the bottom of the packaging.

[0014] The packaging according to the invention can be manufactured cost-effectively from both sheet steel and aluminum sheet steel with low energy and material expenditure according to the methods also disclosed herein, has no weld seams, so that there are practically no problems with "blackening" and leaks, can be checked for tightness of the seal of the foil lid before filling and enables high filling speeds due to the fillability from the bottom side.

[0015] The sealing flange advantageously extends radially outwards from the packaging wall formed by the frame (away from the center of the dispensing opening), so that it projects outwards beyond the packaging wall in the plane of the tear-off lid. This allows for a dispensing opening that corresponds to the area of ​​the packaging's interior at the first end of the frame. This ensures that, with a cylindrical interior or one that widens conically from the second to the first end of the frame, a dimensionally stable product can be removed by turning the package inside out. This is particularly advantageous for food products that need to be easily presented in a specific shape for consumption, such as canned tuna or meat pies.

[0016] It is also preferred that the sealing flange has a circumferential rim that limits the sealing surface to the outside.

[0017] If the sealing flange and the packaging base are designed in such a way that the packaging base of a first package can be arranged within the outer edge of an identical second package that defines the sealing area, then good stackability is achieved with simultaneous positive centering of the stacked packages on top of each other by the respective edge of the sealing flange.

[0018] Advantageously, the packaging wall formed by the frame defines an essentially cylindrical interior space. This makes it possible to fill the frame from the second end with a dimensionally stable product and, in the case of packaging with a radially outward-extending sealing flange, to later remove this product without loss of shape by turning the opened package inside out through the dispensing opening at the first end of the frame.

[0019] If the packaging wall and the packaging base are made of identical sheet metal material, in particular identical coated steel sheet or aluminum sheet, which is preferred, the advantage is that only one type of sheet metal material needs to be managed for their production and particularly material-saving manufacturing processes become possible, in which very little sheet metal waste is produced.

[0020] If the packaging base is made of deep-drawn sheet metal, it becomes possible to manufacture the frame and packaging base in at least a partially shared manufacturing process.

[0021] A second aspect of the invention relates to a set of materials for forming packaging according to the first aspect of the invention.

[0022] The material set includes deep-drawn seamless frames for forming the packaging walls. Each frame has a dispensing opening at one end, surrounded by a sealing flange, which can be closed by gluing or sealing a tear-off foil lid onto the sealing flange. At the other end, it has a filling opening through which the interior enclosed by the packaging walls can be filled, particularly when a tear-off foil lid is glued or sealed onto the sealing flange.

[0023] The material set also includes sheet metal lids, which can be used to close the filling openings of the frames by creating a crimped connection between the frame and the respective sheet metal lid. The sheet metal lid then forms the base of the finished packaging.

[0024] If the sheet metal covers are made from a deep-drawn sheet metal material identical to that of the frames, the advantage arises that it is possible to manufacture the frame and sheet metal covers in a manufacturing process that is at least partially combined. However, it is also envisaged that the material set according to the invention is formed from separately manufactured frames and sheet metal covers, or from both jointly and separately manufactured frames and sheet metal covers.

[0025] In a preferred embodiment of the material set, the removal openings of the frames are each closed with a tear-off foil lid glued or sealed onto the sealing flange, so that the interior enclosed by the frame is closed at the first end of the frame and can be filled with a filling material.

[0026] Inventive material sets constitute preferred commercial forms of the invention.

[0027] A third aspect of the invention relates to a method for producing a material set according to the second aspect of the invention. The method comprises the following steps: a) Manufacturing identical deep-drawn, cup-shaped containers, each with a cup opening, a closed cup bottom, a circumferential closed cup wall extending between the cup bottom and the cup opening, and a sealing flange surrounding the cup opening; b) Separating the cup bottoms from the containers in such a way that first container parts are obtained, which consist essentially of the separated cup bottoms, and second container parts are obtained, which consist essentially of the respective cup wall and the sealing flange surrounding the respective cup opening; c) Forming the sheet metal lids from the first container parts and forming the frames from the second container parts.

[0028] The inventive method makes it possible to provide the frames and the cup bottoms in at least a partially joint manufacturing process, which results in significantly less waste being produced and material costs being saved compared to separate procurement of the cup bottoms.

[0029] Advantageously, the cup bottoms are separated from the container along with a portion of the cup wall, such that the separated portion forms a collar of uniform height around the cup bottom. This collar can then be further shaped in a subsequent processing step to form the flanged edge of the lid.

[0030] In a preferred embodiment, the method further comprises the step of sealing or gluing tear-off foil lids onto the sealing flanges of the second container parts, such that the cup opening is completely closed by the tear-off foil lid. This provides second container parts in which the interior enclosed by the frame is closed at the first end of the frame and can be filled with a product from the second end of the frame.

[0031] It is further preferred that, after sealing or gluing, a leak test is carried out on the second container part, which is fitted with the tear-off foil lid. In this way, leaking second container parts can be sorted out before filling, thus guaranteeing high packaging quality.

[0032] In yet another preferred embodiment, the method additionally comprises the step of forming the collars of the first container parts, or forming the collars of the first container parts and the ends of the cup walls of the second container parts that form the filling opening, in each case such that these areas can be further formed in a subsequent step to create a crimped connection between one of the first container parts and one of the second container parts, in order to close the filling opening of the second container part with the first container part. In the material set produced with this embodiment, the frames and the sheet metal lids are thus already prepared for the production of the crimped connection between them.

[0033] It is preferred that any necessary reshaping of the end of the cup wall of the second container part forming the filling opening takes place before sealing or gluing the tear-off foil lid onto the sealing flange.

[0034] The sealing flange of the cup-shaped container is preferably designed such that it extends radially outwards from the cup opening (i.e., away from the center of the cup opening) so that it projects outwards beyond the packaging wall in the plane of the tear-off foil lid. This makes it possible to provide a dispensing opening that corresponds to the area of ​​the packaging's interior at the first end of the frame, allowing for the removal of a dimensionally stable product by turning the opened package inside out, especially in the case of a cylindrical interior or an interior that widens conically from the second to the first end of the frame. This is particularly advantageous for food products that are to be easily presented in a specific shape for consumption, such as canned tuna or meat pies.

[0035] It is also preferred that the sealing flange be designed in such a way that it has a circumferential rim that limits the sealing surface to the outside.

[0036] Advantageously, the cup-shaped container is manufactured in such a way that the packaging wall formed by the frame defines an essentially cylindrical interior space. This makes it possible to provide material sets in which the frame can be filled with a dimensionally stable product from the second end, and this product, in embodiments with a radially outward-extending sealing flange, can later be removed without loss of shape by turning the opened package inside out through the dispensing opening at the first end of the frame.

[0037] In a further preferred embodiment of the method, the deep-drawn cup-shaped containers are each produced from a sheet metal blank, which is punched out at the place of manufacture of the cup-shaped container from a sheet metal web, in particular coated, especially made of sheet steel or aluminum sheet.

[0038] In yet another preferred embodiment of the method, the tear-off foil lids are die-cut from a film web at the manufacturing site of the cup-like container. This can be done outside or inside the sealing device.

[0039] This offers the advantage that the material set can be manufactured in a continuous process at one location from semi-finished materials, without the need for intermediate storage and / or transport of intermediate products.

[0040] A fourth aspect of the invention relates to a method for producing filled packages according to the first aspect of the invention. The method comprises the following steps: a) Manufacturing identical deep-drawn, cup-shaped containers with a cup opening, a closed cup bottom, a circumferential closed cup wall extending between the cup bottom and the cup opening, and a sealing flange surrounding the cup opening; b) Separating the cup bottoms with a portion of the cup wall from the respective container in such a way that a first container part is formed from the separated cup bottom together with the separated portion of the cup wall, wherein the separated portion of the cup wall forms a collar of uniform height around the cup bottom, and that a second container part is formed from the remaining cup wall and the sealing flange surrounding the cup opening, wherein the end of the remaining cup wall facing away from the sealing flange forms a filling opening;c) Sealing or affixing tear-off foil lids to the sealing flanges of the second container parts in such a way that the cup opening is completely closed by the tear-off foil lid; d) Forming the collars of the first container parts or forming the collars of the first container parts and the ends of the cup walls of the second container parts that form the filling opening in such a way that these areas can be formed in a further step into a crimped connection between one of the first container parts and one of the second container parts, so that the first container part closes the filling opening of the second container part; e) Filling the second container parts with a filling material after sealing or affixing the tear-off foil lid over the filling opening;and f) closing the filling openings of the filled second container parts with one of the first container parts by adjoining the first container part to the second container part and creating the flared connection between the first and the second container part.

[0041] In this process, one or more sets of materials are produced according to the second aspect of the invention and these are processed into filled packages according to the first aspect of the invention by filling the second container parts and closing the filling openings with the first container parts.

[0042] It is preferred that the filling opening of each filled second container part is closed with a first container part which has previously been separated from this second container part.

[0043] Alternatively, it is preferred that the filling opening of each filled second container part is closed with a first container part which has been separated from another of the second container parts.

[0044] In the event that individual first container parts are lost or become unusable, it is also provided that these first container parts are replaced by separately manufactured sheet metal lids.

[0045] In a preferred embodiment of the method according to the fourth aspect of the invention, the forming of the collar of the respective first container part, which is used to close the filling opening of the respective second container part, takes place during the period in which any forming of the end of the cup wall of the second container part forming the filling opening, the sealing or gluing of the tear-off foil lid to the sealing flange of the second container part, and / or the filling of the second container part are carried out. In this way, continuous production can be achieved without costly intermediate storage of the first container parts.

[0046] Any necessary reshaping of the end of the cup wall of the second container part that forms the filling opening is advantageously carried out before sealing or gluing the tear-off foil lid onto the sealing flange. This significantly simplifies the handling of the second container part for the forming step.

[0047] The sealing flange of the cup-shaped container is preferably designed such that it extends radially outwards from the cup opening (away from the center of the dispensing opening) so that it projects outwards beyond the packaging wall in the plane of the tear-off foil lid. This makes it possible to provide a dispensing opening that corresponds to the area of ​​the packaging's interior at the first end of the frame, allowing for the removal of a dimensionally stable product by turning the opened package inside out over the dispensing opening, especially in the case of a cylindrical interior or one that widens conically from the second to the first end of the frame. This is particularly advantageous for food products that are to be easily presented in a specific shape for consumption, such as canned tuna or meat pies.

[0048] It is also preferred that the sealing flange be designed in such a way that it has a circumferential rim that limits the sealing surface to the outside.

[0049] Advantageously, the sealing flange and the packaging base, or the crimped connection between the first and second container parts, are designed such that the packaging base of the first package can be positioned within the outer edge of the sealing flange of an identical second package, which defines the sealing area. This results in good stackability of the manufactured packages with simultaneous positive centering of the stacked packages against each other by the respective edge of the sealing flange.

[0050] The cup-shaped containers are preferably manufactured such that they have a substantially cylindrical interior. This makes it possible to fill the second container sections from the second end of the frame with a dimensionally stable product and, in embodiments with a radially outward-extending sealing flange, to later remove this product without loss of shape by turning the opened package inside out through the dispensing opening.

[0051] In a further preferred embodiment of the method, the deep-drawn cup-shaped containers are each produced from a sheet metal blank, which is punched out at the place of manufacture of the cup-shaped container from a sheet metal web, in particular coated, especially made of sheet steel or aluminum sheet.

[0052] In yet another preferred embodiment of the method, the tear-off foil lids are punched out from a foil web at the manufacturing site of the cup-shaped container.

[0053] This offers the advantage that the packaging can be manufactured in a continuous process at one location from semi-finished materials, without the need for intermediate storage and / or transport of intermediate products.

[0054] Before filling the second container sections, it is advantageous to perform a leak test on each section, which is fitted with a tear-off foil lid. This allows leaking sections to be removed before filling, thus ensuring high quality in the filled packages. Brief description of the drawings

[0055] Further embodiments, advantages, and applications of the invention will become apparent from the dependent claims and from the following description with reference to the figures. These figures show: Fig. 1 a perspective top view of a tuna can according to the invention with a tear-off foil lid; Fig. 2 schematically the production of a material set according to the invention for forming the tuna can from Fig. 1 ; and Fig. 3 schematically the production of the tuna can from Fig. 1 starting from the material set made of Fig. 2 . Ways to implement the invention

[0056] Fig. 1 shows a perspective top view of a packaging according to the invention in the form of a three-part can filled with tuna with a tear-off foil lid.

[0057] The can comprises a seamless frame 1 made of coated sheet steel produced by deep drawing, which forms a can wall 6 enclosing the circular cylindrical interior of the can.

[0058] At its upper end T (claimed first end), the frame 1 forms a dispensing opening surrounded by a sealing flange 2, which is closed with a tear-off foil lid 3 sealed onto the sealing flange 2 and is therefore not visible. The tear-off foil lid 3 has a tear tab 14 by means of which it can be pulled off the sealing surface of the sealing flange 2 to open the can.

[0059] At its lower end B (claimed second end), the frame 1 is connected by a flange 12 to a sheet metal lid 4, which forms the can base 7. The sheet metal lid 4 is made of the same material as the frame 1.

[0060] As can be seen, the sealing flange 2 extends radially outwards from the can wall 6 formed by the frame 1, so that it protrudes outwards over the can wall 6 in the plane of the tear-off foil lid 3.

[0061] The sealing flange 2 and the packaging base 7 are designed such that the packaging base 7 of a first can can be arranged within the outer edge 5 of an identical second can, which defines the sealing surface.

[0062] This results in good stackability of the cans with simultaneous form-fitting centering of the stacked cans on top of each other by the edge 5 of the sealing flange 2 of the respective lower can. Fig. 2 schematically shows the production of a material set according to the second aspect of the invention for forming the tuna can. Fig. 1For the sake of simplicity, only the production of a frame 1 and a lid 4 is shown. As can be seen, this starts with a deep-drawn cup 9 (claiming cup-shaped container) made of coated sheet steel, which has a cup opening, a closed cup bottom, a circumferential closed cup wall 6 extending between the cup bottom and the cup opening, and a sealing flange 2 surrounding the cup opening. The sealing surface of the sealing flange 2 of the cup 9 is bounded on the outside by an upwardly projecting rim 5.

[0063] In a first processing step, the deep-drawn cup 9 is divided into a first cup part 10 (claiming first container part) and a second cup part 11 (claiming second container part) by separating the cup bottom together with a portion of the cup wall 6a. The first cup part 10 consists of the separated cup bottom together with the separated portion of the cup wall 6a, wherein the separated portion of the cup wall 6a forms a collar of uniform height surrounding the cup bottom. The second cup part 11 consists of the remaining cup wall 6b and the sealing flange 2 surrounding the cup opening.

[0064] In a further step, the separated first and second cup parts 10, 11 are transformed into a frame 1 and a sheet metal lid 4 of the material set 1, 4. For this purpose, the collar 6a of the first cup part 10 and the end B of the cup wall 6b of the second cup part 11, which will later form the filling opening, are shaped such that these areas can be formed in a further step into a flanged connection 12 between the sheet metal lid 4 formed from the first cup part 10 and the frame 1 formed from the second cup part 11, for tightly sealing the filling opening of the frame 1 with the sheet metal lid 4.

[0065] Fig. 3 schematically shows the production of tuna cans according to Fig. 1 starting from frame 1 and sheet metal covers 4 according to Fig. 2 For the sake of simplicity, only the production of a can of tuna is shown and described here.

[0066] As can be seen, a frame 1 and a sheet metal cover 4 are arranged according to Fig. 2 and a tear-off foil lid 3 is provided and the tear-off foil lid 3 is sealed onto the sealing flange 2 of the frame 1, such that the original cup opening is completely and tightly closed by the tear-off foil lid 3. The tear tab 14 of the tear-off foil lid 3 is folded towards the center of the can.

[0067] After sealing the tear-off foil lid 3, the tray 1 is turned upside down so that the tear-off foil lid 3 points downwards and the filling opening formed by the bottom end B of the tray 1 points upwards. In this orientation, the tuna filling 13, in the form of a dimensionally stable press cake, is then introduced through the filling opening into the can interior 8 enclosed by the can wall 6 of the tray 1. This interior has a cylindrical shape complementary to the shape of the press cake, so that the interior 8 is practically completely filled with the tuna filling.

[0068] Preferably, before filling the frame 1, a leak test is first carried out on the frame 1 which is equipped with the tear-off foil lid 3, which is not shown here.

[0069] After filling, the sheet metal lid 4 is placed on the bottom end B of the frame 1 and then a flanged connection 12 is made between the sheet metal lid 4 and the frame 1, thereby sealing the frame 1 tightly at its bottom end.

[0070] After closing the filling opening with the metal lid 4, the now finished tuna can is turned upside down so that the tear-off foil lid 3 points upwards and the metal lid 4 forms the can bottom 7.

[0071] While preferred embodiments of the invention are described in the present application, it should be clearly pointed out that the invention is not limited to these and can also be carried out in other ways within the scope of the following claims.
