Description

Device for opening transport containers made of sheet metal. The invention relates to a device on sheet metal vessels, especially those with larger contents, which, for example, contain soft soap to the lid, bottom or other Part of the vessel through which access to the contents is to be made possible, conveniently to be able to remove.

There are already devices for opening the lid of sheet metal vessels known, in which, however, a part of the lid is always destroyed or unusable when opened is made. In no case was the lid immediately back on after removing it from the vessel useful.

In the device according to the present invention, the opening of the Vessel by simply bending open the beaded edge of the closure stiffener achieved a metal band guided from the inside to the outside, so that up to this edge part the shape of the closure part (lid) remains unchanged. Further use the closure part is therefore given, since its shape is still readily available on the Closing opening fits and the tight closure again by flanging the edge can be achieved.

In the drawing, the subject matter of the invention is in two embodiments brought to the illustration, namely shows: Fig. i a vertical section through the metal container and the lid with the opening device in Opinion.

Fig.2 shows the same section, but in a different embodiment in partially open condition.

Fig. 3 shows the tear tape of the embodiment shown in Fig.2 in single view with rectangular and round cross-section.

Fig. 4 partially shows a sheet metal container suitable for soft soap in view, partially in section and Fig. 5, the lid with the tear tape the first embodiment according to Fig. i, seen from the inside.

The edge of the vessel i is beaded around a wire 2 in a known manner. The lid 3 is then crimped with its edge around the beaded edge of the vessel, wherein the tear tape 4 is also crimped. The latter is in the embodiment according to Fig. i in the middle of the lid completely centered to the edge around the center 5 rotatably guided, so that thereby the tape receives a safe guide when torn. The free end of the tear tape 4 is provided with a ring 6 for easy gripping.

In the embodiment of Fig. 2, the tear tape 4 is with the Lid only connected as long as the vessel is still closed, up to the point in time where the lid 3 is completely lifted from the vessel i.

The band 4 (Fig. 3) is significantly shorter in this second version held, but reinforced at the inner end 7 so that it is not off the lid can solve. When tearing open, this reinforcement located inside the container is used as a stop and is guided around the wall of the container in a circle until the Lid is freed from container i at all points of the circumference.

Claims (2)

PATLNTANSPRÜCII C: i. Device for opening transport vessels made of sheet metal, in which the closure parts are fastened by flanging around a bead-shaped edge provided on the vessel jacket, characterized in that a metal band is crimped between the closure part and the vessel edge, which is led from the inside to the outside and which is stretched when it is tightened and thereby the piece of the beaded edge of the closure part lying above the metal band is bent open, whereupon by pulling the metal band transversely to the stretching direction on the circumference of the closure part, its bead is gradually bent open over the entire circumference. 2. Device according to claim i, characterized in that the metal strip by rotatable fastening on the inside of the lid or by appropriate Reinforcement of its free end part located inside the vessel against pulling out is secured.
