DE10021117A1 - Large metal or plastic container with ribbed walls for storage and transport of hot-filled hazardous industrial chemicals with cylinder having a cylindrical mantle and two circular flat ends - Google Patents

Abstract

A container especially barrel made of sheet steel or plastic has a cylindrical mantle and two circular flat ends. In addition to the conventional horizontal circular ribs at top, bottom and selected points, the steel vertical walls are strengthened by a regular polygonal pattern of embossed or pressed e.g. regular hexagons.

Description

The invention relates to a large-volume industrial packaging container such as B. a bung or lid barrel made of sheet steel or plastic. Such Packaging containers or barrels are used for the storage and transport of u. a. also used environmentally hazardous liquid or solid contents.

A bung usually has a cylindrical barrel jacket, a disc shaped barrel bottom and a corresponding barrel top. in the The transition area between the barrel jacket and the barrel top is a circumferential support and transport ring (handling ring = L-ring) provided. In the top of the barrel at least one, preferably in a recessed bung housing (bung) arranged, gas- and liquid-tight closable bunghole opening with designed according to the upstanding bung.

In the case of a lid barrel, the barrel body, which is open at the top, is placed on top Drum lid and clamping ring lock closed. The barrel lid can also be used with a or two bung openings.

Anyone for the storage and transportation of particularly dangerous liquid Packaging containers suitable for filling goods must have an official approval certificate audited and approved. The container must meet certain requirements are sufficient and, for example, sufficient stacking capacity, drop resistance and Have tightness.

It is an object of the invention to provide a large-volume industrial packaging container for the storage and transport of especially hot filled goods ben who has all the necessary performance characteristics and performance data for a official approval and in particular increased rigidity against negative pressure after hot filling. The radial and / or axial strength or rigidity of the Barrel jacket should be increased.

Such a packaging container (= structured barrel) according to the invention with the technical teaching defined in claim 1 realized. The sub-claims included further advantageous design variants.

Important features of the packaging container according to the invention are from the Drawings can be seen.

The invention is illustrated below with reference to the drawings Exemplary embodiments in the form of barrels with vaulting structure explained in more detail and described. Show it

Description of the vault structure for barrels

Among large-volume packaging containers, there are in particular barrels with a Barrel size from about 60 to about 300 liters, preferably from about 220 liters understand. The barrel cross-section is circular with a cylindrical or almost cylindrical barrel jacket. The barrel material consists of sheet steel for steel - sheet pile or lid drums and made of thermoplastic material for preferably blown shaped PE-HD bung or lidded drums.

The vaulting is structured in the cylindrical barrel jacket area. The vault structure is advantageously - without providing additional material or an increase in wall thickness - an increase in radial and / or axial strength of the barrel jacket achieved.

In the case of steel drums, the vault structure is produced by pressing and embossing or rolling the barrel frame and with plastic barrels in blow molding in one correspondingly structured blow mold.

Embodiments

The exemplary embodiments are for 216.5 l steel sheet drums and for 216.5 l art Drawn fabric lid drums (approx. 585 mm, drum height approx. 880 mm).

The arch structure elements according to the invention can have different shapes:

• - in hexagonal design, hexagon border hexagon, the element Execution is recessed inwards in the center and on the outer edge of the element designed to be sublime;  
• - In circular design of the Wöfb structure elements border circle to circle; the element design is recessed in the center of the circle and along the circumferential lines raised on the outside;
• - diamond-shaped design of the vaulted structure elements border rhombus on rhombus, the center is recessed inwards and outwards on the outer edge of the element sublime;
• - The quadrilateral design of the vaulted structure elements adjoin the square Square, the center is recessed inwards and on the outer edge of the element raised on the outside;
• - in a modified design is a circumferential row of vaults Structural elements deepened inwards in the element center and in the neighboring row the vaulted structure elements are raised to the outside.

The differently designed vault structure elements can also be used together be carried out in combination.

The width of a structural element is z. B. 32 in a row next to each other Vault structure elements distributed over the circumference, preferably about 56 mm, at 24 Structural elements in a row approx. 75 mm, and with 20 structural elements in one Row about 92 mm. The best barrel jacket rigidity is achieved when the maximum depth of a vault structure element - on the cylindrical barrel diameter related - for steel drums between 2.5 mm to 4 mm, preferably about 3 mm, and for plastic drums between 3.0 mm to 8 mm, preferably about 4 mm. The large-volume industrial packaging containers designed according to the invention are characterized in particular by the fact that they are excellent for storage and Transport of hot filled contents are suitable. The higher rigidity against Formation of negative pressure after hot filling saves material because less Wall thicknesses with constant radial and axial strength or rigidity of the Barrel can be realized.
