Container for small portioned media

Container packaging is available in various variations. It is tapered towards the removal point and has a predetermined breaking point that is activated by turning a tab. In containers with an applicator, the tab is then exposed.

After filling, a film is sealed under heat and pressure onto the open end of the container to form a base for the container. Once activated, these containers can be placed back on the sealed film without the remaining contents leaking out. The disadvantage of these containers is the heat generated when the sealing film is sealed. The container can deform and the film can warp, which in particular affects stability.

Description of the invention

The object of the invention is to further develop the above-mentioned container, in particular with regard to its stability in the opened state and a reduction in deformation and distortion.

The implementation of these criteria is achieved through the design of the closure and the resulting possible methods for connecting the container and the lid.

According to the invention, the container is closed by means of a smooth or pre-formed lid or one produced by injection molding. The lid can be designed as a single lid, as a latch or as multiple latches. The lid has a centering projection in the form of a profile, the external dimensions of which are slightly smaller than the internal dimensions of the container's filling opening. The profile, which is inclined towards the filling material, reduces the air space between the lid and the filling material. The lid and container are preferably connected by means of ultrasonic welding. This only involves a small amount of heat development and therefore only a small amount of

Warping and deformation of lids or containers. Other joining options such as cut-off welding with the same advantages can also be used.

Description of the implementation examples

Figure 1 shows an open (left) and a closed (right) container 1.0. This consists of a receiving body 3.0 and a closure 2.0 designed as a lid. The receiving body 3.0, preferably an injection-molded part, has a rotating tab 3.2 opposite its filling opening B, and above it a notch 3.3, which serves as a predetermined breaking point.

The upper end of the container 1.0 is widened to an edge 3.1, which forms a circumferential standing collar that runs at right angles to the central axis M. The standing collar 3.1 serves as a connection zone to the closure 2.0.

Figure 2 shows the container according to Figure 1 with an applicator 3.4 in section and a lid as closure 2.0, which can be manufactured using both deep-drawing and injection molding processes.

In the left illustration you can see the receiving body 3.0 in an unfilled state. Above it is the lid 2.0. The lid 2.0 has a profile in the form of a centering projection Z. The cross section b of the centering projection Z is slightly smaller than the cross section a of the filling opening B of the receiving body 3.0.

&iacgr;&ogr; After filling the receiving body 3.0 with the filling material F, the lid 2.0 is placed on the receiving body and is automatically centered, since the centering projection Z preferably protrudes into the receiving body 3.0 (Figure 2, middle) in a form-fitting manner and thus also reduces the remaining air space L in the container. The tight connection zone V between the receiving body 3.0 and the lid 2.0 is preferably achieved by ultrasonic welding.

Figure 2 on the right shows the opened container placed on the surrounding base S of the lid 2.0 with the rotating tab 3.2 broken off and the applicator 3.4 exposed.

Figure 3 shows various variations of the closure. The first representation shows the embodiment already described in Figure 2 with the lid 2.0 with a trough-like depression 2.2 as a profile that forms the centering projection Z.

Lid 4.0 differs from lid 2.0 in that it has no recess; instead, it is thickened in the area of the centering projection Z, so to speak, it is "solid". This results in a full-surface base S in the finished container.

A further embodiment of the lid 5.0 has a nose-shaped extension 5.1 on the side that is inclined towards the filling material F; this receives an applicator 5.2.

Figure 4 shows a second embodiment of the assembled container with the lid 5.0. The applicator 5.2 inserted in the nose-shaped attachment 5.1 is centered in the neck 3.4 of the receiving body 3.0 after being assembled and is exposed after the container head 3.5 is turned off.

For efficient production, it is advantageous to produce both the holder body and the cover in multiple versions:

&iacgr;&ogr; The upper illustration in Figure 5 shows multiple lids in the form of a bar 7.0. After filling all the receiving bodies, which are also combined as a bar 6.0, the locking bar 7.0 is placed on the bar 6.0 and welded. The final external shape X of the base is achieved by punching.

In separation welding, the individual shape is created during the welding process.

Both the receiving body and the lid in their various embodiments can be designed independently of one another as individual elements, latches or multiple latches and connected to one another; a multiple latch 8.0 of lids is shown as an example.
