Description

Field of engineering

The invention relates first to a method for producing a plurality of aluminum caps, wherein an aluminum cap has an aluminum cap part and a plastic part, which each form part of an outer surface of the aluminum cap, further used for producing the plastic part Plastic has a material color and the plastic part of each of the plurality of aluminum caps produced has a surface with a color design, and moreover, the plurality comprises at least a first and a second subset, all plastic parts of the first subset have a matching first color design and all plastic parts the second subset have a matching, but different from the first color design, second color design.

State of the art

Aluminum caps of the type in question are known. It is, for example, on the WO 2013/149844 A1 ( US 2015/0298414 A1 ). Such caps serve in particular the assignment to containers for receiving a pharmaceutical substance, so on, for example, to be arranged on an ampoule. The aluminum closure cap can be designed as a crimp cap, wherein an aluminum cap part serves as part of the aluminum closure cap, in particular for the holding arrangement of a rubber-like sealing stopper in the region of the container opening. The plastic part as a further part of the aluminum closure cap may be used, assigned to the aluminum cap part as a cover part and / or as an overcap. Plastic parts made of polypropylene (PP) or polyethylene (PE) are known in this regard. The plastic part may further form a tamper-evident closure for the aluminum closure cap as a whole.

With regard to the plastic part, it is known to produce this example. In plastic injection molding. Also, pressing methods are known in this context. To produce the plastic part, in the known solutions, a coloring additive may be added to the base polymer in order to give the desired color to the plastic part. A possible change in color of the plastic parts, as results in the production of a first subset and a color differing second subset, proves to be complicated in this conventional method, as for example. When produced in the plastic injection process, a time-consuming conversion period with respect to the plastic Spraying machine is created and can be incurred until the consummate conversion significant amounts of rejects.

Summary of the invention

In view of the above-described prior art, the object of the invention is to specify an improved method for producing a multiplicity of plastic parts.

A possible solution of the problem is given according to a first inventive concept in a method in which it is geared to that all plastic parts of the plurality are made of a plastic of the same material color and that the first and / or second color design by printing each of the plastic parts of the relevant Subset is generated.

The proposed method makes it possible to make a color change in the production of plastic parts without a costly conversion to the plastic injection machine itself. It is no longer necessary to provide differently colored plastic granules as base polymer. The different colors only need to be stored as printer ink. It is so, starting from plastic parts made in a same material color, allows to produce customized plastic parts in terms of color design.

It is thus possible, for example, first to produce a subset of a large number of plastic parts of a plastic material color in a first color and, preferably, virtually uninterrupted, hereafter a subset of plastic parts of the same starting material color in a second color or color scheme. The color change between two subsets of plastic parts of the aluminum caps is so effective, cheaper and faster enforceable. The color change can change in the context of a continuous manufacturing process of a plastic part to the next next plastic part.

The invention further relates to a method for producing a plurality of aluminum caps, wherein an aluminum cap comprises an aluminum cap portion and a plastic portion, each forming part of an outer surface of the aluminum cap, further wherein an aluminum cap portion is a cap portion surface having a cap color design, and further wherein the plurality comprises at least a first and a second subset, all aluminum cap parts of the first subset have a matching first cap color design and all aluminum cap parts of the second subset have a matching, but different from the first cap color design, second cap color design. Also in this context, reference should be made to the prior art already discussed. In particular to the WO 2013/149844 A1 , from which it is known in this context, adjust the color of the aluminum foil by means of a plastic layer.

On this basis, the invention has the object to provide an advantageous method for the production of aluminum caps.

This object is achieved in the subject matter of claim 2, wherein it is pointed out that the first and / or second cap color design is produced by printing each of the aluminum cap parts of the relevant subset.

According to the proposed solution results in an effective, inexpensive color design of the aluminum cap parts. By printing the aluminum cap parts an individual adjustment, especially color design is possible. Even in the course of a continuous production of a variety of aluminum cap parts a change in the color design between two subsets of aluminum cap parts is made possible without interruption. This results in a cost effective and effective production. A storage of aluminum sheets with different colors can be omitted.

The printing devices used for printing on the plastic parts and / or the aluminum cap parts can be designed for single-color printing or for multi-color printing, for example in the RGB or CNYK color space. In particular, the color printing results from the application of pigments or dyes to the surface of the plastic parts or aluminum cap parts.

The colors can be common basic colors (for example red / yellow / blue or, for example, red / green / blue or, for example, yellow / magenta / cyan), but also mixed colors. The colors may be differentiated by the temperature sensation, resulting in warm and cold colors, further through the portion within the electromagnetic spectrum for perceptible color stimuli between 380 and 780 nm.

The printing can be done with a conventional ink jet printer having a print head supplied via ink cartridges with color ink. In this connection, so-called continuous-ink-jet printers can also be used in which the ink jet exits the print head via a nozzle and this ink jet is modulated by way of a piezoelectric transducer.

Also, a so-called drop-on-demand printer can be used, in which targeted individual drops of ink are ejected from the print head.

Further, for example, a pad printing method can be used, in which printing ink is transferred from a cliche via an elastic pad, for example. Of silicone rubber, on the surface to be printed. By such a pad printing and curved surfaces, in particular convex, concave or even irregularly curved surfaces can be printed. In addition, curved surfaces can also be printed by inkjet processes up to a comparatively small radius of curvature.

Also, in this context, a direct UV printing is possible, in which preferably special UV ink is applied to the surface, for example via an inkjet printer or a pad printer, and finally a hardening of the ink application by an ultraviolet light source takes place.

Especially with a coloring of partial surfaces of the plastic parts and / or aluminum cap parts and screen printing is possible. Furthermore, complete or partial printing by spraying may also be provided.

In a preferred embodiment, the printing method and the printing inks used are adapted to the intended use of the printed parts, so for example in the present case for the production of aluminum caps approved for the pharmaceutical sector.

The colors and / or patterns may be indicative, for example with regard to the pharmaceutical substance stored in the container and / or, for example, with regard to the dosage.

A usual layer thickness of the paint application may, for example, be 1 to 10 μm, but possibly even up to, for example, 20 μm, in which case, in particular, paint jobs can be used which, for example, are also used in the food industry.

Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 1 and / or claim 2 or with features of further claims. But they can also be in an assignment to only individual features of claim 1 and / or claim 2 or the respective further claim or each independently of importance.

Thus it can be provided in a development that the color design of the plastic parts of all subsets of the plurality of aluminum caps is produced by printing on each of the plastic parts of the plurality of aluminum caps. In a production of the plastic parts, for example. In the plastic injection molding process, the plastic, from which all subsets of plastic parts are made, can result in a surface-side color design, which is selected according to a desired color design of a subset of plastic parts. Thus, for the color distinction of the subsets of the plastic parts to each other, if necessary, only the one or more further subsets to be printed in a different color design. Also, the selected plastic may have an overall neutral color design, possibly a transparency, according to which the color distinction of the subsets of plastic parts each subset of the printing on the surface side are designed differently in terms of color design.

This may also apply with respect to the aluminum cap parts, wherein the cap color design of the aluminum cap parts of all subsets of the plurality of aluminum caps may be created by printing on each of the aluminum cap parts of the plurality of aluminum caps.

In particular, the areas subjected to color design by printing may be wholly, i. based on the overall color to be decorated surface, uniform, possibly the same color and this case may further be provided with the same continuous pattern. However, the first and / or second color design or the first and / or second cap color design can also be composed of a plurality of differently shaped partial surfaces or cap partial surfaces. These different partial surfaces may differ with regard to the color selection, color temperature and / or the color brightness, but also alternatively or in combination with respect to a patterning. The design of a second partial area may also result from a plastic or cap material not printed in this area.

The plastic part may be designed disk-like, for example. To form a substantially transverse to a container axis of a container on which the aluminum cap is applied or is applied, extending cap cover or the like. The disc-like design may well include a circumferential, up against a disc bottom rising edge. According to one embodiment, such a circumferential edge can be fixedly connected to a facing edge section of the aluminum cap part and can have a peripheral tear-off zone in the connection region to the disk-shaped section of the plastic part. By dissolving the plastic part, for example. According to the rotation of the plastic part relative to the fixed aluminum cap part or in the course of lifting off aufhebbarer Verrastung between plastic part and aluminum cap part, the disc-like portion of the plastic part or the plastic part is a total to expose an opening, eg Puncture opening for a cannula or the like, liftable.

The disk-like configuration of the plastic part preferably has a circular disk-shaped floor plan design.

The printing can be made only on an outwardly facing surface or cap part surface. Here, the outwardly facing surface refers to a lying in the usual field of view for the user. Thus, for example, in the case of a plastic part serving as a closure and tamper-evident part after removal of the entire plastic part or of a partial section of the plastic part from the aluminum closure cap, the surface not visible before acceptance, in particular the lower surface, may not be printed according to the surface. Accordingly, the underside may have a different color from the surface, for example the basic color of the respective part, for example the plastic starting color in a plastic part or the aluminum color in the case of an aluminum cap part. An outwardly facing surface or visible surface can also result only after an operational removal of a portion of the aluminum cap.

Advantageously, according to the proposed method, an aluminum cap member can be made by deep drawing from an aluminum strip, the aluminum strip preferably being printed before deep drawing to produce the cap color design. This results in a favorable color design, since in this case a printing of the material surface takes place in two-dimensional printing. In a preferred embodiment in this case takes place a uniform, more preferably pattern-free or over the surface of the same pattern printing with a color. However, it is also possible in this case to print a partial area or to print with different partial areas, in which case, as a result of the subsequent forming process, pattern patterns in the conversion areas can be taken into account in the printer position. Alternatively or additionally, a printing of the produced (formed) aluminum cap part can be done.

In addition to a uniform and as a closed surface or partial area performing color printing are also possible with respect to the color design of the plastic parts and / or the aluminum cap parts, especially color, pattern imprints, imprints or typefaces.

In addition, for example, instructions or texts in general, possibly also in color, applied, further example. Identification means, such as. Barcodes (2D or 3D).

In a further embodiment, it is also possible to apply so-called micropatterns, which may only be recognizable by optical magnification. Such micropatterns are preferably applied in the inkjet process. Special optical devices or appropriately equipped devices, such as smartphones, can be used to detect and, if necessary, to encode the micropattern.

Such a micropattern can be used for serialization, for example in place of a matrix code, or as a tamper-evident indication. The latter can also be achieved by printing a UV ink, which is readable only under a UV light source.

Furthermore, the invention relates to a use of one-sided printed disc-like plastic parts to produce a color design as part of an aluminum cap, which comes as an overcap on a pharmaceutical substance containing and an elastomeric closure member having container used.

Moreover, the invention relates to a use of aluminum cap parts printed to produce a cap color design as part of an aluminum cap, which is used as an overcap on a container containing pharmaceutical substance and having an elastomeric closure part.

With regard to further features in connection with the respective use, the same applies to their demanding assignment as described above with respect to the process-related features.

Description of the embodiments

Shown and described, first with reference to the 1 and 2 , an aluminum cap 1 for placement on a container in the manner of an ampoule or the like.

The aluminum cap 1 has initially and essentially an aluminum cap part 3 on which, for example, from a flat aluminum strip 4 , like this example in the 11 and 13 is shown, in a not shown combined punching and forming process (deep drawing process) can be transformed.

The aluminum strip 4 may consist of an aluminum solid material or even, as from the above-mentioned WO 2013/149844 A1 known, from a laminate consisting of a metallic film layer, which may be coated on the upper and lower sides with a plastic layer.

The aluminum cap part 3 has a capped ceiling 5 and a preferably perpendicular to the cap blanket 5 and in the state of use downwardly extending cap partition wall 6 on. The center is in the cap part ceiling 5 an opening 7 punched out, which ultimately on the container 2 Applied state, such as, for example, in 2 is shown by a plate-like plastic part 8th can be covered.

In the in the 1 and 2 illustrated embodiment is the aluminum cap 1 on the upper part of the container 2 applied. In the mouth of the container 2 is an elastomeric stopper 9 used by the aluminum cap part 3 is covered on the upper side and flange side. The aluminum cap part 3 is further preferred to the lower handle to a container mouth edge 10 bent (crinkled). The relevant lower cap edge part can in the course of applying the aluminum cap part 3 on the container 2 by a pusher tool to rest against the container 2 , in the illustrated undergrip according to 2 to the mouth edge 10 to be pressed.

On the aluminum cap part 3 the plate-shaped plastic part 8 is further applied from above.

The plastic part 8th can in detail a plastic part cover 12 preferably over the entire surface of the aluminum cap portion 3 , its cap part ceiling 5 covering, extending. Preferably, the plastic part 8th made of a hard plastic, for example. Produced in plastic injection molding.

The underside is on the plastic part 8th can according to the illustrated embodiment, an extension 11 molded, one to the opening 7 in the aluminum cap part 3 adapted diameter. At the end the extension gives way 11 a collar-like radial extension 13 on, in the covering position according to the 1 and 2 the edge area of the opening 7 engages below.

The plastic part 8th can by tearing off the aluminum cap part 3 be removed. The radial extension 13 has elastic by the acting tensile force, so that the rear grip position is canceled.

The aluminum cap part 3 continues in the usual way, the already mentioned top-side opening 7 on. The opening 7 is according to the state in 2 from the plastic part 8th covered. After removing the plastic part 8th is the opening 7 for piercing through the sealing plug 9 free.

The preferred in a variety V in a manufacturing device 14 manufactured aluminum cap parts 3 or plastic parts 8th are preferably at least one in the application arrangement according to the 1 and 2 visible surface (initially) in each case the same material color or color design.

The manufacturing device 14 can in the case of making an aluminum cap part 3 a punching and bending device, in the case of the production of a plastic part 8th For example, as also preferred, a plastic injection device.

The color design of the respective surface can be given solely by the surface design by the material used, so for example in the cap part 3 through the material used aluminum. In a plastic molded part, for example. Plastic part 8th , The preferred consistent color design of the plurality of plastic parts 8th be given by the plastic material used, but possibly also by appropriate color additives in the starting plastic material.

So can further in particular the variety V the plastic parts 8th have a (partially) transparent or opaque color design.

A preferred different color design of subsets of the plurality V is achieved according to the invention by printing each individual part of the plurality V , The printing can according to the examples in the 5 to 10 take place after production of the part to be printed or even, according to the embodiments in the 11 to 14 , here in particular in context with the aluminum cap part 3 , before a final manufacturing process, for example. Punching and bending process.

By the proposed printing of laying down on the container 2 finished parts (aluminum cap part 3 or plastic part 8th ) or the aluminum strip 4 before the punching and bending process a different color design of the respective surface of the parts is made possible, so that in a uniform manufacturing process in the field of manufacturing 14 finally, first and second subsets T ₁ and T ₂ the variety V of parts, with the first subset T ₁ one opposite the second subset T ₂ can have different color design.

It can be a printing device 15 be provided. This may, as exemplified in 5 schematically illustrated to an ink-jet printing device 21 optionally, a UV direct printing device, further optionally followed by a UV curing device 22 ,

By means of the printing device 15 If necessary, only the surface of the part pointing outwards and if necessary also partially visible when using the part may be printed. For example, in the use state according to 2 upward facing flat side of the plastic part cover 12 or the cap blanket 5 (see. 7 and 8th ). It can only be a partial area 16 be provided with a color design, for example. A uniform uniform color design.

Also, for example, in an ink-jet printing process, two partial surfaces 16 and 17 be provided with different color design. In this case, as shown in FIG 10 around subareas 16 and 17 within a, for example, in a common plane extending ceiling surface or the like act. Also, the second part surface 17 extend in another plane, like the face 16 , Thus, for example, the outwardly facing surface of a partial ceiling may have a different color design than the outwardly facing surface of the collar adjoining the ceiling or the surrounding wall.

In addition, for example, the ceiling surface and the outwardly facing surface of the circumferential wall or the collar as shown in FIG 9 be the same color. Accordingly, a preferably identically designed printing takes place in at least two mutually different planes extending, for example, at right angles to one another.

For this purpose, for example, a printing in the tampon process can offer further, as shown by way of example and schematically in FIG 6 is shown. This is printing ink 18 through an elastic tampon 19 from a printing form 20 on the part to be printed, here aluminum cap part 3 or plastic part 8th , transfer. Due to the elastic design of the printing ink 18 transferring tampons 19 results in a high adaptability to the surface to be printed. Thus, even convex or concave curved surfaces can be printed conveniently. In addition, as shown in 6 an over the edge of the facing surface beyond printing the subsequent section, here the cap part wall 6 or the outer surface of a peripheral plastic part edge, can be achieved.

In addition, aluminum strips can also 4 according to the representations in the 11 and 13 be processed according to one of the above-described printing method with respect to their surface color design.

11 shows an aluminum strip 4 whose top is provided in the region of one of the flat sides with a continuous same color design. For this surface side consistently uniformly colored aluminum strip 4 becomes a correspondingly on the outwardly facing surface uniformly colored aluminum cap part 3 as shown in 12 punched and deep-drawn. Accordingly, the outwardly and in the state of assignment upwardly facing surface of the cap part ceiling 5 and the outwardly facing surface of the circumferential cap partition wall 6 an identical color scheme. Here, the surface of the cap part ceiling forms 5 a first partial area 16 and the surface of the cap part wall 6 a second subarea 17 ,

Also, in the course of printing the aluminum strip 4 ie before production of the aluminum cap part 3 by punching and deep drawing the aluminum strip 4 , a color design with different color faces 16 and 17 be achieved.

So can the aluminum strip 4 for example, as shown in FIG 13 , with a circular disk-shaped partial surface 16 be printed in a first color design and with a part of the surface forming the remaining surface of the surface 17 in a second color scheme.

The first part surface 16 Can after punching and deep drawing of the aluminum strip 4 the correspondingly colored surface of the cap part ceiling 5 form while the color is different than that subarea 16 designed partial surface 17 on the outside of the hood part wall 6 reflects.
