Abstract
An element (1) punched out in a cover shape, for sealing of containers (7), includes a first ply (2) and a second inner ply (3) which is provided with a heat-sealable layer (5) on its side facing the container. The plies (2, 3) are connected to one another over their surface sides (2′, 3′.) facing one another by a cold-sealing layer (4), the adhesion between the plies (2, 3) being lower than that between the inner ply (3) and the container edge (8). On the inner ply (3) there can be scoring (10) which is exposed by peeling off the outer ply (2). If for example packaged material which is suited for heating in a microwave oven is stored in the container (7), the steam which forms during heating can escape through the scoring (10).
Description
- This invention relates to an element which is punched out in a cover shape for sealing of containers, consisting of a first outer ply and a second inner ply which is provided with a heat-sealable layer on its side facing the container.
- The use of two-ply covers for sealing of containers in order for example to enable the flavor protection which is required for foods is known.
- Furthermore it has been shown that especially in the case of perishable foods, for the consumer there is an increased demand for information relating to origin, contents, and storability. In order to provide enough space for this information, there has been a transition to printing it on the outer ply of the sealing cover, conversely the inner ply remains unprinted as much as possible. This is the case since possible contact of printing inks with foods is to be avoided.
- To open these packages the upper ply of the cover is pulled off and only after separating the inner, second ply is access to the package contents possible.
- But known approaches have the disadvantage that this partial opening process is often difficult, since sometimes the entire cover, therefore the two plies, are pulled off the container. But this is undesirable when flavor protection for the packaged contents is to continue to be maintained by the second inner ply. This is necessary for example for larger package contents which can only be consumed in portions, but also in packages for microwave dishes.
- Therefore the object of this invention is to devise an element of the initially mentioned type which is punched out in the shape of a cover, which preserves the package contents in a satisfactory manner, especially with respect to flavor protection, and which can be easily handled in a for the consumer when opening [sic].
- As claimed in the invention, this object is achieved with an element which is punched out in a cover shape and which is characterized in that its plies are connected to one another over their surface sides facing one another by a cold-sealing layer, and that the adhesion between the plies is lower than that between the inner ply and the container edge.
- This varied adhesion makes it possible for the consumer to easily partially open the container such that in the first opening step the outer ply is pulled, i.e. peeled, off the inner ply facing the container. In a second step the inner ply is pulled off the container edge, an increased force being necessary since the heat-sealable coating adheres more strongly to the container edge than the cold-sealing layer between the individual compound plies.
- Other embodiments of the element which is punched out in a cover shape as claimed in the invention are disclosed according to the dependent claims.
- The invention is detailed below using possible embodiments of the invention.
FIG. 1 shows one possible embodiment in which the ply of the element which is punched out in a cover shape, which ply faces the container, has an inherently closed surface. According toFIG. 2 this surface is provided with scoring, as shown inFIG. 3 with perforations for forming a pour opening. As shown inFIG. 4 , the inner ply of the element which is punched out in a cover shape is made in the form of a lattice. - In the production of the
element 1 which is punched out in a cover shape as claimed in the invention, for the present theouter ply 2 or theinner ply 3 is produced. - For producing the
outer ply 2, for example aluminum foil with a thickness in the range from 10 to 100 microns is used. It is however also possible to use plastic films in the thickness range from 10 to 100 microns. The plastics can be selected from the group polypropylene, polyethylene, polyester, polyacrylate, polyamide, or polystyrene. - The
outer ply 2 can furthermore be provided with typography on its surface 'side facing the viewer. It can be both smooth and also rough in its surface configuration. The surface roughness yields the desired typography by the irregular, but also regular arrangement of the print motifs. Furthermore the surface roughness of the typography facilitates the unstacking of the elements which are punched out in a cover shape and which are conventionally stored on top of one another in magazines. - The aforementioned typography can however also reproduce the information from which the consumer takes the origin, composition and storage life of the packaged material.
- After printing the
outer ply 2, it is provided with a cold-sealinglayer 4 on itssurface side 2′. Cold-sealing substances are characterized in that by using pressure, but without additional temperature use, adhesion between two plies can be produced. The cold-sealing layer can be prepared for example by applying a polymer-containing emulsion or dispersion. Polymer emulsions in aqueous form can be for example those with the commercial name “Crodaseal 22-055″ since they meet legal requirements relating to food. Furthermore it is conceivable to use a likewise food-compatible, softener-free polymer dispersion based on acrylic acid ester copolymers in water with the commercial name “Flexbond®”. - Regardless of the aforementioned production or lamination process of the
outer ply 2, theply 3 facing the container is produced or prepared in a further process step. It consists for example of plastics in a monostructure or compound structure, the thickness range from 10 to 100 microns being chosen. The plastics can be chosen from the group polypropylene, polyethylene, polyester, polyacrylate, polyamide, or polystyrene. - Then the
inner ply 3 facing the container is provided on itssurface side 3″ facing the container with a heat-sealable layer 5. It can be made for example from a hot sealing wax or a peelable plastic film. It is furthermore conceivable for the heat-sealable layer 5 to be applied by coextrusion coating. It is important that by choosing the heat-sealable compounds, their chemical composition and the degree of their crosslinking in the heat-sealing process, adhesion between theinner ply 3 and thecontainer edge 8 is produced such that it is greater than that adhesion which is produced by the cold-sealinglayer 4 between theplies - It is furthermore advantageous that the heat-
sealable layer 5 is made with a rough surface, since this greatly facilitates the unstacking of the cover elements which are conventionally stored on top of one another in magazines. The execution of the surface-rough heat-sealable layer 5 in the form of geometrically arrangedspacers 6 is especially advantageous. These spacers, due to their geometrical arrangement, enclose air in the likewise regularly arranged intermediate spaces so that the aforementioned unstacking process is additionally facilitated. A rapid unstacking process is especially of great advantage when, as in the case of perishable foods, they must be sealed especially carefully and airtight when being packaged. - The
inner ply 3 of thecover element 1, which ply is produced for example in this way, can now have an inherently closed surface, as is shown inFIG. 1 . - According to the embodiments as shown in
FIGS. 2 and 3 , theinner ply 3 however can also have scoring 10 or perforations 11. - The
scoring 1 0 is produced for example by slight punching and is used to enable escape of the steam which may be formed when microwave dishes are heated, without fouling the microwave oven. - The inner ply can furthermore be provided with perforations 11 which constitute for example the form of a pour opening 12. It is formed in a partial opening process and for large package contents also enables partial removal of the packaged material.
- Another possible embodiment of the element which is punched out in a cover shape is shown in
FIG. 4 . Here theinner ply 3 facing the container has the shape of abroken lattice 14. Thislattice 14 consists oflengthwise filaments 15 andcrosswise filaments 16 which are formed from heat-sealable plastics, for example from polypropylene, polyethylene, polyester, polyacrylate, polyamide, or polystyrene. Thelattice breaches 17 which are formed between the lengthwise andcrosswise filaments - After producing or preparing the
outer ply 2 and theinner ply 3, they are joined to one another over theirsurfaces sides 2′ and 3′ which face one another by the cold-sealinglayer 4 in a cold lamination process. This takes place for example in a lamination station consisting essentially of a laminating roller pair, theplies layer 4 which is attached for example to theply 3 is facing thesurface side 3′ of theply 3 which is guided over the second laminating roller. Due to the contact pressure which is formed in the roll gap, at room temperature via the cold-sealinglayer 4 an adhesive connection takes place over thesurface sides 2′ and 3′ of theplies sealable layer 5 remains in the deactivated state, i.e. no crosslinking reactions of any kind which cause adhesion which is undesirable in this stage take place. - The
plies surfaces 2′ and 3′ by the cold-sealinglayer 4. This combination is stored as rolled goods from which the elements for sealing can be punched out in the corresponding cover shape. In doing so there can also be formation of an opening aid, for example a pull tab 9, 9′, at locations free of cement. Thesecover elements 1 which are ordinarily stored in magazines can now be used for other applications, i.e. for sealing ofcontainers 7. Thecontainers 7 which can be filled with yoghurt, but also free-flowing packaged materials such as spices, salt or pepper, are continuously sealed with theelements 1 which are punched out in a cover shape as claimed in the invention in a heat sealing process. By using pressure at an elevated temperature the chemical compounds in the heat-sealable layer 5 are activated such that adhesion is produced in the range of greater than or equal (≧) 5 N/15 mm (measured according to DIN EN 28510-1 “Peel test for flexibly/rigidly cemented samples”) between thecover element 1 and thecontainer edge 8. This adhesion even after partial opening of thecontainer 7 results in that it is sealed at least partially airtight. To open it, as is shown in FIGS. 1 to 4, the pull tab 9 which is located in theouter ply 2 is gripped and pulled in the direction of the arrow F1. The adhesion between theplies outer ply 2 can be pulled entirely or partially off theunderlying ply 3. So that in this opening process thecover element 1 can in fact be partially peeled off, the adhesion between theouter ply 2 and theinner ply 3 is in the range from 0.2 to 4.5 N/15 mm (measured according to DIN EN 28510-1 “Peel test for flexibly/rigidly cemented samples”). - In order to be able to measure the average peeling force which is a characteristic quantity for the adhesion on the one hand between the
container edge 8 and theinner ply 3 and on the other hand between theouter ply 2 and theinner ply 3, to perform the peel test, samples of the compound partners, specifically the container material and theinner ply 3 on the one hand and theinner ply 3 and theouter ply 2 on the other, are produced in the form of partial combination. Thus, as claimed in the invention there is a partial combination of thecontainer material 7, the heat-sealable layer 5 and theinner ply 3 and a second partial combination of theinner ply 3, the cold-sealable layer 4 and theouter ply 2. For the peeling test, 15 mm wide and roughly 300 mm long strips are cut out of these partial combinations in the running direction. Then the compound partners are separated from one another on the ends of the samples by hand so that the free ends can be clamped in the clamping means of a tensile testing apparatus, for example from the Zwick company. The test proceeds at a pulling rate of 100 mm/min, a clamped length of a maximum 50 mm and a pulling angle of 90°. The measurement result or the variation of the peeling strength (adhesion) is either read on the tensile testing apparatus or is recorded with a diagram recorder. The average values in N/15 mm are computed from the results of each test series. - As is shown in
FIG. 2 c, it will be necessary to pull off theentire ply 2 from theply 3 since this embodiment of thecover element 1 as claimed in the invention is suited for sealing of microwave containers. Here theply 2 which consists for example of aluminum will be pulled off before use in the microwave so that aluminum does not disrupt or prevent the passage of microwaves. The steam which forms during heating can escape through the scoring 10 so that fouling of the microwave oven is prevented. - When the
container 7 is partially opened, as is shown inFIG. 3 c, however by applying the tearing force F1 at the same time a pour opening 12 is formed. This takes place by making a tear along the perforations 11 so that on theouter ply 2 which has been pulled off theply 3 the corresponding shape of the pour opening 12 remains adhering. In this embodiment it is sufficient for theouter ply 2 to be pulled off only partially at least in the area of the pour opening 12 in order to enable partial removal of the packaged material via this pour opening 12 for the consumer. For further storage it is possible, by pressing theouter ply 2 against theply 3, to ensure a type of resealability of the package. This takes place by the corresponding selection of the cold-sealing layer 4 which can be present for example in the form of a pressure-sensitive cement. - Even in the application as is shown in
FIG. 4 b, by pulling on the pull tab 9 in the direction of the arrow F1 at least in part the lattice-shapedstructure 14 is exposed. By means of the lattice breaches 17 a free-flowing packaged material, for example spices, salt or pepper, can be removed. In this form of packaging it will also be sufficient for theouter ply 2 to be only partially pulled off theunderlying ply 3. - In summary, it can therefore be stated that by differently setting the adhesion between the
plies container edge 8 and thecover element surface 3, an opening mechanism can be initiated in a purposeful manner such that theplies cover element 1 can be pulled off from one another in whole or in part. If theouter ply 2 is pulled completely off theinner ply 3, for example the scoring 10 on theinner ply 3 is exposed. If at this point packaged material which is suited for heating in microwave ovens is stored in thecontainer 7, the steam which is conventional during heating can escape through the exposed scoring 10 so that unwanted fouling of the microwave oven is prevented.
