Description

Packaging vessel The invention relates to a packaging vessel, in particular on a barrel with a thin-walled jacket and one with a double-fold connection Folded-in cover or base, which in the area of the head edges with the jacket edge outside or inside surrounding reinforcing rings is provided, the reinforcing rings and the jacket in the area outside of the folded seam joint with a joint Bead are provided, the largest diameter of which is larger than the outer diameter the edge connections and the reinforcing beads distributed over the jacket, and the end of the reinforcing ring opposite the folded edge through an im Container jacket provided inner or outer bead is supported.

To protect against mechanical effects during transport and during Use is made of the seam connections between jacket and cover or. Coat and The edge of the base is already surrounded by head reinforcement rings. The protective effect occurs, however in these arrangements not always to the desired extent, as the legs the surrounding rings are particularly suitable for the heavy loads that occur therefore often expand because the ring is self-supporting in terms of its load-bearing capacity and is therefore not sufficiently resistant.

There are also known vessels in which the vessel jacket is in the area the head edge is reinforced by inner rings, these rings with their the end facing away from the folded joint on an inner bead provided in the container jacket prop up. All known reinforcement ring arrangements have proven to be particularly at risk the vessel mantle points proved to be in the area of the transition from reinforcement to the container wall. Apart from that due to the strong execution of the well-known Reinforcement rings caused large material consumption, is the economy when using the first-mentioned, known reinforcing rings for this reason alone mostly unfavorable because the rings are subjected to an expensive pre-deformation and because of the high stresses that occur during the drawing process from high-quality and so that expensive material must be made.

In contrast, the task of the invention consists in the case of packaging vessels Of the type in question, it is particularly favorable in terms of strength and at the same time very good economic type of jacket-cover or. Achieve coat-floor connection.

To solve the problem of the invention, invention according to proposed that the reinforcement ring with its outermost, bent folded edge together with the folded edge of the vessel jacket from the lid or. Bodenfalzrand is completely enclosed. The new solvents in the present and neighboring field leave one new, surprising effects arise.

A particularly favorable embodiment of the proposed invention is seen in the fact that the folded edge of the reinforcement ring together with the folded edge of the vessel jacket is bent outwards by about 1800 and both edges are common are enclosed by the lid or bottom rebate edge.

Another special embodiment of the proposal is represented in that the folded edge of the reinforcing ring together with the The folded edge of the vessel jacket after an initial angle of approx. 1800 inwards, after the subsequent straight course again around 1800 in the same way Direction is bent and the two foremost bends of the folded edge of the Mantle and the folded edge of the reinforcement ring together from the lid or bottom folded edge are enclosed.

The proposals according to the invention result in packaging vessels of the type in question by crimping the edge of the reinforcement ring into the Connection between the edge of the vessel jacket and the edge of the lid or base and by enclosing it This fold through the bottom or cover fold edge has a special strength in terms of strength favorable jacket-cover or base connection.

The deformations that may arise during transport or the like essentially kept out of the area of the particularly sensitive connection points and introduced into the areas of the vessel jacket or lid, the such Deformations allow without breakage. Without prior deformation the deformation of the ring wall together with the fold formation of the lid or

Floor jacket edge done in one operation after the relative thin-walled reinforcement is pulled onto the edge of the jacket.

- The invention is explained with reference to the drawing.

The -Fig-t- and 2-4eaeils sections through the vessel are on the Mantel-Dewcke1z.-or. Shell-floor connection.

As can be seen in particular from Fig. 1; with 1 the coat ' des --vessels, whose folded edge 2 is bent outwards by around 1800.

The outermost folded edge 3 of the reinforcement ring surrounding the jacket 1 from the outside. 4 is angled together with the folded edge 2. The two folded edges 2 and 3 are-from Lid or Bodeufalzrand 6 enclosed, the outermost end between the outer jacket of the reinforcement ring 4 and its folded edge 3 is clamped. The one not bent Part of the reinforcement ring 4 extends beyond the fold area and runs a piece straight and concentric to the vessel jacket. Below the transition point from the reinforcement ring 4 to the vessel jacket 1, the jacket is provided with a bead 7, on which the reinforcement ring 4 is based. Jacket 1 and reinforcement ring 4 have continue to have a common bead 8, the outer diameter of which is greater than that Outside diameter of the head edges and the reinforcing beads distributed over the vessel jacket 1.

From Fig. 2 it can be seen on the basis of an exemplary embodiment, that the folded seam can also be placed in such a way that it does not exceed the diameter of the vessel protrudes. Here, jacket 1 and reinforcing ring 4 are common at their end angled twice inwards by 1800 in the same direction, whereby the lid or Bottom fold edge 6 in a hanging arrangement, the fold edges 2, 3 of jacket 1 and reinforcement ring 4 includes.
