[0013] At least one of the components presented here may also have been manufactured using the following 3D printing methods, which are not listed exhaustively. 1. The FDM (Fused Deposition Modeling) process

[0014] Alternative names: Fused Filament Fabrication (FFF), Fused Layer Modeling (FLM). This process involves the layer-by-layer application (extrusion) of a material through a hot nozzle. The consumable material is in the form of a long wire (filament) on a spool and is fed by the feed unit into a print head, where it is melted and deposited onto a build platform. The print head and / or build platform are movable in three directions, allowing layers of plastic to be applied one on top of the other. 2. The SLS process (Selective Laser Sintering)

[0015] Unlike sintering, where powdered materials are fused together under heat, SLS selectively uses a laser (alternatively an electron beam or infrared beam). Only a specific portion of the powder is fused together.

[0016] A thin layer of powder is applied to the print bed by the coating unit. The laser (or other energy source) is then precisely aimed at specific points within the powder layer to create the first layer of the print data. During this process, the powder is partially melted and then solidifies again upon slight cooling. The unmelted powder remains around the sintered areas and serves as support material. After a layer has solidified, the print bed lowers by a fraction of a millimeter. The coating unit then moves across the print bed and applies the next layer of powder. The second layer of the print data is then sintered by the laser (or other energy source). In this way, a three-dimensional object is created layer by layer. 3. Three-Dimensional Printing (3DP)

[0017] The 3DP process works very similarly to selective laser sintering, but instead of a directed energy source, a print head moves across the powder. This head deposits tiny droplets of binder onto the underlying powder layers, bonding them together. Otherwise, this process is identical to SLS. 4. Stereolithography (SLA)

[0018] Instead of plastic filament or powdered printing material, the stereolithography process uses liquid resins, so-called photopolymers. These are hardened layer by layer by UV radiation, thus creating three-dimensional objects. For this process, the build platform is lowered step by step into the resin bath. There are also variants (so-called PolyJet processes) that do not use a whole bath of liquid resin. In these, an epoxy resin is applied drop by drop from a nozzle and immediately cured by a UV laser. 5. Laminated Object Manufacturing (LOM)Alternative name: Layer Laminated Manufacturing (LLM)

[0019] The process is based neither on chemical reactions nor on a thermal process. A cutting tool (e.g., a knife or carbon dioxide laser) is used to cut a film or sheet (e.g., paper) along its contour, and the layers are glued together. Lowering the build platform then creates a layered object made of glued, overlapping films.

[0020] Alternatively, materials such as paper, cardboard, corrugated board, pressed board, etc. are also suitable.

[0021] The invention described here will be presented in more detail below with reference to four figures and the accompanying description, whereby it is a Fig. 1 around the adapter element 10, at Fig. 2 around the fill element 50, at Fig. 3 around the container 1 together with the adapter element 10 and the filling element 50, as well as at Fig. 4 is about the cap.

[0022] Fig. Figure 1 shows an adapter element 100 for insertion into an opening of a container 1, which comprises an adapter base body 10 having a substantially circular cross-section and a sleeve-shaped form.

[0023] The Fig. 1, Fig. 2 to Fig. Figure 3 shows that at least one fixing and / or holding element 20 is arranged on the adapter base body 10, so that after the adapter base element 10 is inserted, it remains stuck at the opening of the container 1 or rests on an edge of the container 1, wherein a thread 40 is provided on an inner wall of the adapter base body 10, for example milled, so that a closure or filling element 50 can be attached, through which a container 1, which is then at least partially filled, can be emptied.

[0024] Furthermore, one can see in the Fig. 1, that an outer diameter of the adapter base body 10, wherein the outer diameter is closed by an outer surface of the adapter base body 10, is smaller than an inner opening diameter of a neck piece 60, in order to be able to insert the adapter base body 10 into the neck piece via the opening without resistance, and that an outer diameter of the adapter base body 10, wherein the outer diameter is closed by an outer surface of the adapter base body 10, is larger than or approximately equal to an inner opening diameter of a neck piece 60, in order to be able to insert, for example, plug in, the adapter base body 10 into the neck piece 60 via the opening in the context of a transition or interference fit. Fig. Figure 1 shows that the adapter base body 10 has an internal thread 40 and the adapter base element 100 has an edge-side attachment element 70, which projects in an L-shape from the opening and is designed and intended to rest on the upper edge of the opening after the adapter base body 10 has been fully inserted. Fig. Figure 2 shows that the attachment element 50 has an insertion stop element 70 for the adapter base body 10 and the filling element 50 has an external thread 80, so that the filling element can be screwed into the internal thread 40 of the adapter base body 10 by means of the external thread 80, wherein the filling element 50 has at least one filling opening 90, so that fluid located in the container 1 can be discharged in a controlled and targeted manner via the filling opening 90.

[0025] Furthermore, Fig. 2 can be seen that the filling element 50 has the discharge opening via a geometric center point of the opening 90 of the container neck 60 and that the filling element 50 tapers conically or convexly in the direction towards the discharge opening 90.

[0026] Fig. 3 and Fig. Figure 4 shows that the plastic cap 2 can be fitted flush and securely onto the adapter system 100 in order to withstand external mechanical loads non-destructively through elastic coupling connections and to return to its original state after mechanical relief, whereby a child safety lock must be overcome to remove the cap 2.

[0027] The Fig. 1, Fig. 2, Fig. 3 to Fig.Figure 4 shows an adapter system 1000, comprising an adapter element 10 and an attachment element 50, wherein the attachment element 50 is screwable into the adapter element 10, and a container system 2000 for storing a fluid, comprising a container 1 for storing a fluid, wherein the container 1 has a neck area 60, into which an adapter element 10 and an attachment element 50, wherein the attachment element 50 is screwable into the adapter element 10, can be inserted from above and through the opening.
