DE3939023C1 - Semi-liq. or solid product container - comprises sheet metal rectangular panels, tops folded outwards to form reinforcing channel - Google Patents

Abstract

A rectangular sheet metal container for semi-liquid or solid products includes four vertical sheet metal wall panels (9). The top end of the wall panels are folded outwards so that a reinforcing channel (8) is produced. The horizontal channel edge (10) is secured to the outside of the wall panel by welding seams (14). Triangular hook profiles (15) which are pressed out from the vertical channel wall (12) are used to secure plastic liners inside the container. The top edge of the wall panel (19) forms an angle of about 45 deg. to provide the location for the seal ring (20) on the container lid (7). ADVANTAGE - Rectangular sheet metal container with improved stability is produced with a reduced amount of welding work.

Description

The invention relates to a container according to the preamble of the main claim.

A generic container is e.g. in the DE-34 48 140 C2 described. This well-known container ter is stackable and has a frame construction on the actual container from damage protects and makes it more transportable. This frame construction naturally makes everyone more expensive Container.

DE-GM 17 54 346 is a stackable heavy Sheet steel load container known in its upper area has a peripheral edge profile, in the corner area upwards open elbows are arranged, the lying receiving pockets for form the foot pieces of another container. The Edge profile is directed towards the outside Bending the upper end of one wall of each Formed container-forming panel, this Ab edging is U-shaped. About this bend a reinforcement plate is placed, one inside has lying leg, with its edge on the inside of the panel forming the wall is welded while the outside is longer Thigh with its lower edge on the outside the board is welded on. So this exists Reinforcing sheet from a separate profile, the through several welds on the actual, in  upper area also be profiled bent Be is set on the edge of the container.

The container is lidless and has no circulation with pockets for the forks of a fork stacker equipped floor profile.

The invention has for its object the gat to improve education-forming construction by that in the upper edge area of the container by ent speaking design of the intended here running, one part with the wall of the container gene edge profile compared to the known construct a complex welding work avoiding Simplification is achieved, but at the same time one Improve stability and the required here sealing between the container, the edge and Cover.

This object underlying the invention will solved by the teaching of the main claim.

In other words, it is suggested that the upper edge profile by an outward ge straightened the upper end of each one Wall of the container forming panel is formed, so that a separate profile is not indicated here must be brought. This folding continues out that at the same time a good edition for the in  the actual container lid provided seal is achieved and that this edge continues at the same time to form the so-called sack holder can be used by the the bag holder forming fastening leg from the vertical Legs of the fold are punched out and forward be pre-bent.

The lower horizontal leg is assigned to the neten panel outside by welding where at the welds in the area of the hooks closures can be provided for the lid, so that - since there is a considerable pull on the sewer tion through the closure devices for the lid is exercised - here also the required strength speed is achieved without too large material influences from welding work occur.

At the same time, it is proposed according to the invention that the stability of the container through corner pillars he is increased, which is also achieved by folding be, the marginal edges of the respective panels the walls of the container can be folded that 90 ° corners of the container or flattened corners of the container can be achieved. This flattened Corners of the container have the advantage that the Ent emptying and cleaning is simplified.

Furthermore, it is proposed according to the invention that the container is not exactly vertically aligned Has walls, but that the walls have a certain Taper so that the inside of the container opens and expands something upwards so that thereby also the emptying process considerably can be simplified.

Embodiments of the invention will follow explained with reference to the drawings. The drawing The names show in

Fig. 1 is a view of a container ge according to the invention, in

Fig. 2 on a larger scale, the upper edge with associated lid in section and in view, in

Fig. 3 shows a first embodiment of a corner column and in

Fig. 4 shows a modified version of a corner pillar.

In Fig. 1, a container 1 is shown, which is supported by a bottom profile 2 . This Bodenpro fil 2 has foot pieces 3 and also a travel bags 4 are provided for the forks of a forklift.

In the upper region of the container 1 , an edge profile 5 is arranged, at the corner regions of which angle pieces 6 are provided which are designed such that they can accommodate the foot pieces 3 of another container, so that a stacking of several containers which is secure against displacement is possible. At 7 , the lid of the container 1 can be seen , which is fixed by the closure bracket 18 , which closure bracket 18 are provided all around the four side walls of the container 1 , so that a tight closure of the lid 7 is possible.

The upper edge profile 3 is - as shown more clearly in FIG. 2 - achieved by a bevel 8 . Here too the upper part of a panel 9 forming a wall of the container is bent outwards, so that a U-shaped bend is created. This U-shaped bend has a lower horizontal leg 10 , the ge see partially over its length via welds 14 with the outside of the board 9 is fixed. At the top, a horizontal leg 12 adjoins the horizontal leg 10 and merges into an upper leg 11 . The upper leg 11 but not at right angles to the upper edge of the board 9 , son changes including an angle α, which is less than 90 °, so that the lower end of the upper leg 11 to the vertical leg 12 at an angle β greater than 90 °. Here, a relatively sharp, upper sealing edge 19 is created, on which the seal 20 clamped in the edge of the cover lies when the cover is closed.

Fastening legs 15 are punched out of the vertical leg 12 of the bevel 8 , which are triangularly tapered downwards and into which the plastic bag suspended in the container can be clamped. So there is no separate welding of these so-called bag holders.

Fig. 3 shows a corner pillar, which is formed by a Stabili sierungsflansch 15 . In Fig. 3 is again a side wall forming panel 9 he recognizable, this panel 9 is guided to the outside and is folded in a manner known per se so that the stabilizing flange 15 is created with its ends 16 . As a result, considerable strength of the container is achieved in the simplest way.

Fig. 3 shows that the actual container edge te can be rectangular, while in the illustration in Fig. 4 the marginal edges of the board 9 are bent at an angle δ of about 135 °. This creates a container, the corner regions of which are flattened, so that easier emptying and cleaning of the container is achieved here, especially when pasty substances are stored in this plastic bag.

It is not apparent from the drawings that the Be container can be designed on the one hand so that the Container walls at right angles from the base plate run above or that on the other hand the container so can be designed so that the container walls open on the outside, the inside of the container is conical stalten, so that also a better and easier emptying of the container is possible.
