Description

The invention relates to a packaging and a packaging blank for a packaging and to a production method for such a packaging blank for a packaging for glass bodies.

To transport glass bodies, in particular optical glasses such as spectacle lenses or optical components for optical systems, they are packed in packaging to protect them from damage. The movements inherent in transport, possible shocks and vibrations can lead to relative movements between the packaging and the glass body. These relative movements generate frictional forces, which in turn can influence the surface quality of the glass body itself or a coating or imprint on it. For example, spectacle lenses have hydrophobic coatings in which the relative movements can result in local or even planar abrasion. This also applies to other coatings or informative prints on the glass body. In addition to minimizing the transport movements themselves, packaging must therefore also be provided which largely suppress a relative movement induced by external influences and / or compensate for the surface-damaging effects of the relative movement.

Usually, fleece or film sections are glued into the packaging as protective elements to protect the glass body. The pamphlet EP 2 275 360 A1 proposes a packaging with a protective element, which is formed for example from foam and has a recess.

The use of non-woven or film materials, however, limits the design variety due to the specified materials and their properties. In addition, minimum dimensions must be adhered to in order to ensure that the protective elements are glued in at a later stage with sufficient quality in terms of production technology. Ultimately, the implementation of a profiling that is adapted to the geometry of the element to be protected is associated with considerable production engineering costs.

In view of the disadvantages associated with the prior art, the object of the present invention is to provide a packaging and a packaging blank for packaging and a manufacturing method for such a packaging blank for packaging glass bodies, by means of which the glass body is protected in a simple manner can and increases the variety of designs.

The object of the invention is achieved by a packaging for a glass body according to claim 1, a packaging unit according to claim 7, a packaging blank for a packaging for a glass body according to claim 10 and a manufacturing method for a packaging blank according to claim 16. Further advantageous configurations of the invention emerge from the subclaims.

According to the invention, the packaging for a glass body comprises at least two packaging areas opposite one another when used appropriately to form a receiving opening for the glass body, the at least two opposite packaging areas each having an inner side facing the glass body when used appropriately. At least one inner side of the at least two opposite packaging areas has at least partially an anti-slip coating.

The expression "in an application-oriented use" serves to indicate the orientation reference of the packaging areas and inner sides. For those skilled in the art it is evident that the application-oriented use requires the introduction of a Provides glass body in the packaging. Correspondingly, the use of the expression “in an application-oriented way” enables a more unambiguous position assignment compared to the use of the solely non-reference terms “above”, “below”, “inside” or “outside”.

A “coating” is understood to mean a material which is applied by an application process, such as printing, spraying or roller processes, and which forms an adhesive layer on it. The coating can also be applied to a carrier material which is later connected to or placed on the surface to be provided with the coating using other connection methods, such as adhesive methods.

The use of coatings, which can be designed in one or more layers, increases the design options, such as the setting of spatially resolved properties, both in the area of the surfaces facing the glass body in application-oriented use and in the area perpendicular to the surface. For example, even in the case of a multi-layer structure of the coating, layers that do not come into direct contact with the contact body, properties can be set that serve for improved cushioning, but may not have the desired slip resistance. In such a case, the slip resistance of the coating is implemented via the layer of the multi-layer coating that comes into contact with the glass body.

The anti-slip property of the coating reduces the tendency for relative movements between the packaging and the glass body when the glass body in the packaging comes into contact with the coating. It is preferably provided that the packaging size is designed such that the glass body to be packaged is in permanent contact with the coating in the packaging state over at least one coating area and is thus held as long as no external influences exceed the holding force exerted via the packaging with the coating. The coating is preferably applied at least in the area or areas in which or in which there is contact between the packaging and the glass body during relative movements Packaging and glass body is likely. As an alternative or in addition, the coating is applied at least in one area or areas in which, in the event of contact between the packaging and the glass body in connection with a relative movement between the packaging in the glass body, an influence on the surface quality must be expected. If glass bodies have, for example, informative prints, the legibility of which is no longer guaranteed in the event of abrasion, the coating would be provided at least in the areas that are in contact with the print or could come into contact. The at least partial coating in sensitive contact areas is particularly advantageous if these areas are also to be protected against external influences in the form of impacts or compressive forces. If the coating is elastic, it also offers cushioning in such cases. Alternatively, the coating can also be applied in areas that are less sensitive to other areas. In this case, the coating serves to hold the glass body and, at the same time, to keep the sensitive areas at a distance from possible contacts to the packaging. If the glass body to be packaged is designed as a lens and there is an imprint outside the apex of a convex surface, the coating can be applied to the inside of the packaging area facing the convex surface of the lens in the area of the apex. The coating holds the lens centrally, while at the same time the print located outside the apex remains spaced from the inside of the packaging.

The coating is preferably applied to the packaging in a shapeless state, in particular in a fluid state. An "informal state" is a form of application of a medium that does not have a given shape in the sense of a geometric shape, such as a film cutout according to rectangular, round or other structural specifications, but the later form of the coating on the packaging through the application of the informal coating medium is determined. The shape of the coating is produced over a given area of application and in the height direction through the amount applied in one or more layers.

In particular, the coating is applied in a fluid state, in particular in the form of a viscous liquid. The fluid state is accessible to a large number of application methods, so that the coating application can be implemented in a simple manner. In addition, liquids can wet a substrate well and, depending on the suitability of the combination of coating medium and substrate, produce a direct adhesive bond. The suitability can also be established or improved by means of adhesion promoters. It can also be seen from this that the coating does not necessarily have to be applied directly to the packaging substrate, but that intermediate layers, such as those of an adhesion promoter, can also be provided. Powder materials or mixed forms, such as pastes, are also conceivable as alternative coatings. Depending on the coating medium used, curing mechanisms, such as UV radiation, or crosslinking mechanisms, for example for polymerization, can be used to adjust the coating properties.

The application of the coating in a shapeless state also makes it possible in a simple manner to set locally different coating properties by using different coatings. In this way, for example, property gradients, in particular with regard to coefficients of friction, can be generated. For this purpose, different coatings are applied one after the other and / or in parallel in a temporal sense, or further additives are added to a coating as required. Height profiles can also be generated through different coatings or application settings, such as partially higher application quantities and / or partially different numbers of layers. The flexibility is not limited to purely functional properties, but also enables different colors or optical effects to be set.

In particular, the coating is applied directly to the at least one inside. “Direct application” is understood to mean a coating which has been applied directly to a substrate, here the inside, and which forms an adhesive layer on it. On gluing and the associated disadvantages can thus be waived. The coating can be applied without wrinkles. The risk of warping the substrate is also minimized.

In the case of a direct application, the inside can also have previous coatings, such as a primer, which improves the quality of the slip-resistant coating then applied in terms of adhesion or a penetration property. Previous coatings can also include colored imprints for informational or decorative purposes. In this case, the anti-slip coating has transparent properties, at least in these areas, so that the colored prints remain recognizable. Alternatively or in addition, if the slip-resistant coating is applied to different prints, the slip-resistant coating then being different in each case, the slip-resistant coating can also have opaque properties, so that information from the print only becomes visible after the slip-resistant coating has been removed. Corresponding “hidden information” can then no longer be recognized without destroying the anti-slip coating, which can be used in the context of control procedures.

It has been found to be advantageous that the coating comprises a lacquer with silicone components, preferably is formed from this. Paints with silicone components have a slip-resistant effect without sticking to surfaces that come into contact. In particular, the varnish has predominantly silicone components, preferably 90% by weight to 100% by weight, particularly preferably 96% by weight to 99% by weight. In an exemplary embodiment, a 1% by weight proportion of a catalyst is added to a starting lacquer with 100% by weight silicone, so that a lacquer with a silicone content of 99% by weight is obtained for the coating.

The coating preferably has an application rate of 2 g / m ² to 10 g / m ² , preferably 3 g / m ² to 9 g / m ² , in particular 6 g / m ² to 8 g / m ² . If the amount applied is too low, there is no adequate anti-slip effect. Due to the costs associated with increasing order volumes, but also the With the increase in weight and the space required, sufficient slip resistance is achieved with the upper limits specified here.

Advantageously, the at least one inside, preferably starting from the center of the inside, has the coating over an area of 50 mm x 70 mm to 60 mm x 170 mm, preferably over the entire area or structured, in particular in the form of stripes or lines , Dots and / or circles and / or in a kind of herringbone pattern. In addition to the structuring in the sense of a pattern, the mentioned geometrical characteristics can also be provided as a single coating geometry element. In the case of a lens body, the convex lens side can, for example, be held in an annular, slip-resistant manner by means of a circular coating.

An area of 50 mm x 70 mm to 60 mm x 170 mm covers the area in the case of conventional spectacle lenses in which the spectacle lenses in the packaging can have a smaller distance to the inside of the packaging area facing them due to their curvature compared to their outer areas. Universal protection of endangered areas is implemented in a simple manner through the full-surface application. A structured order can also be carried out to reduce the order quantity. In addition, a structured order can also be an option if the number of possible contact surfaces is to be reduced. In particular, care can be taken to ensure that the structure leaves out the areas in which no contact with sensitive surface areas of a glass body is to be expected. However, if it is precisely the sensitive surface areas that should not experience any contact situations as far as possible, structuring should be provided on the inside of the packaging area, which come into contact with rather insensitive surface areas of the glass body.

The coating can only be applied to the inside of the packaging areas in order to reduce the amount of coating when areas of a glass body to be protected are only present on one side, for example. However, it can also be advantageous to apply the coating to all inner sides of the packaging areas. This not only provides protection Areas of a glass body to be protected on several sides. Even with areas of the glass body to be protected only on one side, an additional degree of freedom in the introduction of the glass body can result. For example, a lens with an imprint to be protected on a convex side with this side facing one or the other inside of the packaging areas. Thus, the imprint to be protected can also be achieved when the glass body is introduced contrary to its usually intended orientation. Alternatively or in addition, the hold of the glass body in the packaging can be increased by coating more than just one inside of the packaging areas. In a simple embodiment, for example, a mirror-symmetrical coating is provided on the opposite inner sides of the packaging areas. However, it can also prove to be advantageous to apply different contact surfaces on each side to the contact surfaces which are connected to the coating when the glass body is preferably oriented. This can also be applied to the coating of the packaging blank described later.

In one embodiment, the anti-slip coating is colored. The coloring can be done by applying paint after the coating. As an alternative or in addition, the anti-slip coating itself contains corresponding color additives, which means that the step of subsequent application of color can be dispensed with or restricted to partial areas. In this way, decorative and / or informative areas can be designed that also have functional properties.

The packaging areas are preferably made from offset paper or coated paper. Offset papers take up coatings, especially fluid coatings such as paints or varnishes, well, so that adhesion is supported. Coated papers have a coated surface so that they are less absorbent compared to offset papers. Nevertheless, they offer sufficient primer or can be provided with an adhesion promoter, whereby contours and coating boundaries can be depicted more precisely. An absorbent surface, like with offset papers, would have to be treated in advance by a to achieve a comparable effect. The invention is not limited to papers as distinguished from cardboard, but can also be applied to cardboard materials. In principle, the invention can be applied to all common types of paper.

In particular, the opposing packaging areas to form the receiving opening are folded towards one another via at least one folded edge and are connected to one another via at least one side flap on at least one side extending from the receiving opening to the folded edge. This enables a simple construction of the packaging, which is also accessible to packaging made from only one packaging blank. For improved protection against a glass body to be packaged falling out, a closure flap can also be provided which can close the receiving opening for the glass body. The closure flap is formed in a simple manner from a section of a packaging area which is lengthened with respect to the receiving opening and which is folded over a folded edge in such a way that it also encloses the opposite packaging area or engages in the receiving opening formed by the packaging areas. The locking effect can be supported by a form-fitting mechanism, such as engaging a tab in a slot, and / or traps.

The invention also relates to a packaging unit which comprises a packaging as described above and a glass body contained therein.

The glass body is preferably formed from a plastic with a hydrophopic coating. The hydrophobic coating is vapor-deposited under pressure and must be protected from scratches. In particular, however, an imprint applied to the hydrophobic coating must also be protected, which has fixing points for grinding in, for example in eyeglass lenses, for optimal processing of the lens and therefore must not be smeared or displaced. Due to the hydrophobic surface on which the print is applied, it is sensitive to the effects of friction. Up to now, such prints were repeatedly damaged in conventional packaging. In the now proposed packaging unit, the abrasion or shifting of the imprint on the hydrophobic coating can be reduced.

A method for producing the packaging unit, which has a packaging as described above and a glass body contained therein, comprises a step of forming a packaging from a packaging blank, as described below, and a step of inserting a glass body into the packaging. Depending on the design of the packaging, the method can include further steps, such as, for example, closing the packaging using a closure tab after the glass body has been inserted.

The invention also relates to a packaging blank for a packaging for a glass body, comprising at least two packaging areas that are opposite each other when used appropriately and between which a receiving opening for a glass body is formed, the at least two opposite packaging areas each having an inner side facing the glass body when used appropriately . At least one inner side of the at least two opposing packaging areas has at least partially a non-slip coating that is applied in a shapeless state, in particular a fluid state.

The packaging blank is used to produce packaging for a glass body as described above. This is punched out or cut in a simple manner from sheet or web material. Since the result is a two-dimensional cut, it can be seen that reference definitions result from the application-oriented use, i.e. in the later packaging state for packaging a glass body. In particular, the coating of flat material, such as sheets or webs, can be implemented in a simple manner in terms of production technology.

The coating is preferably applied directly to the at least one inside. This results in the advantages already described for the packaging.

It has been found to be advantageous that the coating comprises a lacquer with silicone components, preferably is formed from this. Paints with silicone components have a slip-resistant effect without sticking to surfaces that come into contact.

The coating preferably has an application rate of 2 g / m ² to 10 g / m ² , preferably 3 g / m ² to 9 g / m ² , in particular 6 g / m ² to 8 g / m ² . The advantages already described for the packaging result from this.

Advantageously, the at least one inside, preferably starting from the center of the inside, has the coating over an area of 50 mm x 70 mm to 60 mm x 170 mm, preferably over the entire area or structured, in particular in the form of stripes or lines , Dots and / or circles and / or in a kind of herringbone pattern.

With conventional spectacle lenses, an area of 50 mm x 70 mm to 60 mm x 170 mm covers the area in which, due to their curvature, the spectacle lenses in the packaging can have a smaller distance to the inside of the packaging area facing them than their outer areas. Universal protection of endangered areas is implemented in a simple manner through the full-surface application. A structured order can also be carried out to reduce the order quantity. In addition, a structured order can also be an option if the number of possible contact surfaces is to be reduced. In particular, care can be taken to ensure that the structure leaves out the areas in which no contact with sensitive surface areas of a glass body is to be expected. However, if it is precisely the sensitive surface areas that should not experience any contact situations as far as possible, structuring should be provided on the inside of the packaging area, which come into contact with rather insensitive surface areas of the glass body. The term “structure” thus includes not only regular structures in the sense of a repetitive pattern, but also irregular structures, such as demand-oriented order points, whereby the structured order is spread over Differentiates recessing areas of a reference surface from a full-surface application.

In one embodiment, the anti-slip coating is colored as already described.

Furthermore, the packaging areas are preferably made from offset paper or coated paper.

The invention also relates to a manufacturing method for a packaging blank, as described above, in which the coating is applied, preferably before cutting the packaging blanks, via a flexographic coating unit, a screen printing coating unit, by offset printing or by digital printing.

However, the invention is not fundamentally restricted to the preferred use of coating units in the above-mentioned higher-level printing processes. Finally, other printing processes are also conceivable.

The application of an anti-slip coating must not only benefit the later use to protect a glass body, but can also be used advantageously during the further handling of the packaging blank and / or the packaging formed from it. For example, the transport can be facilitated by the slip resistance and / or advantageous machine settings can be implemented. For this purpose, the surfaces or areas coated for later protection of the glass body can be used or, alternatively or additionally, coatings can be applied in the same application, that is to say without additional process steps.

Even if an order is conceivable in every manufacturing step of the packaging blank, this is an option before the cutting. Since the packaging blank is available as a larger material unit before it is cut, no individual blanks have to be aligned, for example. The application device can also be in a Cutting device can be integrated so that additional handling can be omitted.

In particular, the coating is applied to a packaging material, preferably offset paper or picture printing paper, in the form of a material tape or in the form of material sheets.

As already mentioned with regard to the preferred application of the coating to the packaging blank prior to cutting, the use of larger material units simplifies handling and reduces the individual consideration of the blanks. Material belts in particular offer endless processing, since the packaging blank to be coated can be fed in continuously. Material sheets can, however, offer advantages in a two-sided coating or other two-sided processing steps in which the packaging blank can be turned as a sheet instead of two-sided application or other processing devices.

Particularly advantageous developments of the invention are the subject of the dependent claims. Features and expediencies of the invention are also described below on the basis of exemplary embodiments with reference to the drawings. From the figures show:

Figure 1 shows an eyeglass pocket 1 as an example of a packaging for a glass body in a perspective view with a view of the packaging areas that are on the inside when used appropriately and the packaging tabs connected to them. In this view, the glasses pocket 1 has not yet been converted into its application-oriented state via the connection of the connecting straps 3, 4. The spectacle lens pocket 1 comprises two packaging areas 2a, 2b, which are opposite one another when used appropriately for the application, to form a receiving opening (9) for a spectacle lens 8 ( Fig. 2 ). In principle, however, more than two packaging areas can also be encompassed by one packaging if this is not designed as a bag, as shown here, but, for example, as a cuboid.

The two packaging areas 2a, 2b opposite one another in application-oriented use each have an inner side 21a, 21b facing the spectacle lens as an example of a glass body in its packaging. These are in Figure 1 each provided with an anti-slip coating 7a, 7b. The coatings 7a, 7b merge into one another or are formed via a continuous application, but can also be spaced apart from one another. Also shows Figure 1 a distance between the coating and the folded or side edges 2a-3, 2a-9, 2b-4 and 2b-5 surrounding the packaging areas 2a, 2b with the exception of the side edge formed by the folded edge 6. The fringing side edges 2a-3, 2a-9, 2b-4 and 2b-5 can be both outer edges, as well as folded edges to other packaging areas or Connecting tabs are formed, for example by the folded edges 2a-3 between the packaging area 2a and the connecting tabs 3 or the folded edges 2b-4, 2b-5 between the packaging area 2b and the connecting tabs 4 and the closing tab 5. By the spacing from the fold - or side edges 2a-3, 2a-9, 2b-4 and 2b-5, not only can the amount of coating be reduced, but also, especially in the case of folded edges, the folding can be facilitated by recesses. However, this is not mandatory, as is clear from the exemplary continuous application of coating on the inner sides 7a, 7b over the folded edge 6.

The glasses pocket 1 has the connecting straps 3, 4 already mentioned. The connecting tabs 3 adjoin the folded edges 2a-3 of the packaging area 2a, which are located on the side of the receiving opening 9 ( Fig. 2 ) for lens 8 ( Fig. 2 ) forming side edge 2a-9 or, in other words, connecting the receiving opening 9 with the forming side edge 2a-9 and the folded edge 6. The connecting tabs 4 adjoin the folded edges 2b-4 of the packaging area 2b, which extend laterally from the folded edge 2b-5 to the closure tab 5 or connect the folded edge 2b-5 to the closure tab 5 with the folded edge 6. The connecting straps 3, 4 are connected to one another on the respective sides of the spectacle lens pocket 1, as a result of which a lateral closure of the spectacle lens pocket 1 is formed, which is intended to prevent the spectacle lens 8 from slipping out laterally. In the in Figure 1 In the example shown, the connecting tab 3 is simple, while the connecting tab 4 has a further folded edge 41, 42, so that the connecting tab 4 is in an area 41 facing the packaging area 2b ( Fig. 3 , 4th ) and an area 42 facing away from the packaging area 2b ( Fig. 3 , 4th ) can be divided. The area 42 of the connecting tab 4 facing away from the packaging area 2b can be referred to as the connecting section and is connected to the connecting tab 3, preferably glued. Understandably, however, the connecting tab 3 can also be designed to be divided and / or the connecting tab 4 can be simple. The connecting tabs 3, 4 do not have to extend over the entire length of the respective folded edges 2a-3, 2b-4, but can only be provided over one or more partial sections. In particular, it has been found to be advantageous proven to cut out areas in the vicinity of adjoining side edges, especially in order to minimize material accumulations in folded edges.

The closure flap 5 adjoins the folded edge 2b-5 of the packaging area 2b facing the receiving opening 9 for the spectacle lens 8, but can also be provided on the side edge 2a-9 of the packaging area 2a facing the receiving opening 9. As shown here, the closure flap 5 preferably has two cutouts 51, which can also be used for an automated closure of the glasses pocket 1. The cutouts 51 can, however, also be provided independently of a use by the system technology for automated closing so that parts of an adhesive surface with which the closing flap 5 can be held in the closed state are not covered in the area of the cutouts. The adhesive surfaces that remain free can thus be used for labeling when a label is applied to the adhesive surfaces.

In the application-oriented use or application-oriented state, the connecting straps 3, 4 are connected to one another on the respective sides of the packaging areas 2a, 2b, so that the glasses pocket 1 is formed over them. Figure 2 shows the glasses pocket 1 in application-oriented use or condition in a sectional view perpendicular to the packaging areas 2a, 2b at a parallel spacing from the folded edges 2a-3, 2b-4 of the packaging areas 2a, 2b to which the connecting tabs 3, 4 adjoin. By folding around the folding edge 6 and the connection of the connecting tabs 3, 4, a receiving opening 9 for the spectacle lens 8 is formed by the latter together with the packaging areas 2a, 2b. The inner sides 21a, 21b of the packaging areas 2a, 2b, which are opposite to one another in this state, have the slip-resistant coating 7 on both sides. The coating 7a, which can be assigned to the packaging area 2a, extends, for example, over a sufficient length in order to be able to implement anti-slip properties for the flat side of the spectacle lens 8. The coating 7b, which can be assigned to the packaging area 21b, is designed in the same way for the convex side of the spectacle lens 8. The coatings 7a, 7b can are executed the same or at least differ in the type of coating medium, the application quantity and / or the application area. For example, different types of coating medium can be used in order to set different coefficients of friction. For example, the coating of an inside of a packaging area that faces a more insensitive side of the glass body when used appropriately for the application can be provided with a higher coefficient of friction through which a high degree of retention against relative movements can be achieved, while a coating with a lower coefficient of friction is applied to the opposite inside that offers less support, but reduces the risk of abrasion when relative movements occur. The use of different types of coating media is not only restricted to a respective packaging area, but can also be provided locally differently within the packaging area. This also applies to the order quantity, which can be varied locally as well as depending on the packaging area. Particularly in the case of glass bodies to be picked up which, according to their geometrical design, do not have a constant distance from the packaging, an increase in the distance between the packaging area and the glass body can be compensated for by increased application of coating material. The variation of the application surface, which not only includes the application surface in the sense of a full-surface coating area, but also the formation of individual structures or some other geometrical formation of a coating, can also be used for a coordination optimized for the respective glass body to be protected.

Figure 2 also shows the closure flap 5 which adjoins the folded edge 2b-5 of the packaging area 2b facing the receiving opening 9. The closure flap 5 is shown here in an open state and is used to close the glasses pocket 1 around the folded edge 2b-5 of the packaging area facing the receiving opening 9 2b folded. For further protection of the spectacle lens, the anti-slip coating can also be applied at least partially to the closure flap. This applies equally to an application of the coating in Figure 2 connecting straps 3, 4, not shown.

The Figures 3 and 4th show a top view of a packaging blank 10 for a glasses pocket 1 as an example of packaging for a glass body, in each case in the direction of view of the inner sides 21a, 21b of the packaging areas 2a, 2b, which are opposite each other when used appropriately for the application ( Fig. 3 ) as well as in the viewing direction of the outer sides 22a, 22b of the packaging areas 2a, 2b ( Fig. 4 ).

Since the packaging blank 10 can be understood as the origin of the packaging 1, i.e. generally a packaging blank can represent the origin of a packaging, statements on the packaging blank 10 and thus packaging blanks in general as well as glasses bags 1 and packaging for glass bodies in general are generally mutually transferable, provided that they are not the apparent characteristics of the respective packaging stage.

Due to the transferability of the packaging blank 10 in the glasses pocket 1 are in the Figures 3 and 4th the same reference numerals are used for the packaging blank 10 as in FIGS Figures 1 and 2 to the glasses pocket 1.

As already stated for the glasses pocket 1, the inner sides 21a, 21b of the packaging areas 2a, 2b have a coating 7 which partially extends over both inner sides 21a, 21b and which can be assigned as a coating 7a to the inner side 21a and as a coating 7b to the inner side 21b.

For this purpose, the coating is preferably applied using a printing process such as flexographic printing, screen printing or digital printing. A lacquer with silicone components, for example, is used as the coating medium. When using varnishes, such as the mentioned varnish with silicone components, but also when using other varnishes suitable according to the invention, printing varnish units are used in particular. However, the basic idea of the invention is not limited to conventional printing processes, but can also be transferred to application processes that can be traced back to painting or spraying the packaging blank. Ultimately, immersion processes are also conceivable.

To transfer the packaging blank 10 into a glasses pocket 1, the connecting tabs 3 are folded along the folded edge 2a-3 in the direction of the inside 21a of the packaging area 2a. The connecting tabs 4 are folded in a similar manner along the folded edges 2b-4 in the direction of the inside 21b of the packaging area 2b, a further fold being carried out along the folded edge 41, 42 so that the area 42 of the packaging area 2b facing away from the packaging area 2b in the original packaging blank state Connecting tab 4 now faces outwards again after folding. The term “outside” here refers to a reversal of the inwardly directed fold in relation to an alignment in the direction of the inside 21b, as is also the case with the perspective view of the glasses pocket 1 in FIG Figure 1 can be found. In addition, the inner sides 21a, 21b of the packaging areas 2a, 2b are folded toward one another along the folded edge 6. As a result, the folded connecting tabs 3 and on the respective sides of the packaging areas 2a, 2b also move towards one another. By folding the in Figure 4 connecting tab sides 31 shown and in Figure 3 The connecting flap sides 421 shown here of the area 42 facing away from the packaging area 2b in the original packaging blank state are approximated and can be connected to one another. The connection is preferably made by gluing the connection tab sides 31 and 421 at least in sections. Depending on the material and configuration, however, other connection methods, such as interlocking connection tabs and connection tab receiving slots, can also be used. In general terms, the connection can be based on material, force-fit and / or form-fit connection principles.

The closure flap can be pre-folded or only folded after receiving the spectacle lens when it is used appropriately.

Complementary is to Figure 4 , which shows the packaging blank in its original state in the direction of view of the outer sides of the packaging areas 2a, 2b facing outwards in application-oriented use, it should be noted that in this example no coating is applied. Such an outside one Coating can, however, be provided so that, in addition to providing slip resistance for the glass body to be packaged, slip resistance between the packs can also be achieved. This additional coating application is possible in a simple manner by rotating the sheet or web material from which the packaging blanks can be punched or cut out, or an application device working on both sides of the material. Particularly in the case of colored coatings, a decorative and / or informative application can thus be carried out at the same time, which can be used functionally at the same time. It can be seen that a decorative and / or informative print can also be associated with the coating of the inner sides 21a, 21b of the packaging areas 2a, 2b.

The invention is not restricted to the embodiments described. The packaging does not have to be designed as a glasses pocket, but can also be a pocket for other optical elements. The type of packaging is also not limited to bags. As further types of packaging, for example, cuboid boxes or other shapes adapted to the glass body to be packaged come into consideration.
