Abstract

A container for storing gas or liquid under high pressure comprises a rotationally symmetrical support foot formed integrally with the lower end of a bottle cylinder and connected to a domed bottom of the bottle. The ratio of the support foot thickness and the wall thickness of the bottle cylinder is at least 2:1. The greatest depth between the bottle bottom and the support foot is at least 15% of the outer diameter of the bottle cylinder. The smallest depth between the bottle bottom and the support foot is at least 9.5% of the outer diameter of the bottle cylinder. <IMAGE>

Description

SPECIFICATION Container for storing fluids under pressure.
The invention reiates to a container for storing gases, acids or other liquid media which are subjected to a high pressure, in particular a steel bottle or the like having a rotation-symmetrical standing base, which is formed in one piece with the lower end of the bottle cylinder and is connected to the domed bottom of the bottle.
As a rule, steel bottles which serve for storing gases, acids or other liquid media which are subjected to a high pressure have a rotationsymmetrical cross-section; in this case the length of such bottles amounts to a multiple of their diameter.
Apart from the fact that bottles which are arranged or stored in an upright position must be secured against toppling over in accordance with the prevailing safety regulations, they must also possess an appropriately satisfactorily constructed support face in order to attain this object.
Known steel bottles are usually produced in one piece in a plurality of working steps. The production is effected in this case by means of hot flow pressing. The support face consists of a separate member, usually in the form of a ring which is shrunk onto the lower portion of the bottle body in a hot state. For certain cases of use, the underside of the support foot ring is additionally widened in a square manner prior to shrinking upon the bottle body, in order to provide the steel bottle thereby with a correspondingly large measure of standing reliability.
It is clear without difficulty that steel bottles of this kind are relatively expensive because of their involved production, in particular since the support feet require additionally a special treatment. In the case of a shrunk-on standing foot, corrosion effects between the same and the bottle body cannot be excluded. Thereby, too, safety risks are produced.
In the search for appropriate simplifications in the production of steel bottles, it has already been achieved successfully to form a standing face directly on the bottle body or the bottle bottom, respectively, by the method of hot flow pressing.
However, not last for reasons inherent in the work material, relatively narrow limits are set to such a support face formed in this way on the bottle body. These limits become evident in particular by the fact that it was impossible heretofore to render the support face correspondingly deep, or high, respectively, in relation to the bottle bottom. However, a commensurate depth, or height, respectively, of the support face is a condition for ensuring also, inter alia, a safe manual transport of bottles constructed in this way. Accordingly they must be constructed in an appropriate manually safely manageable and thereby at the same time also accident-proof manner.
In view of the limits inherent in these or similar known solutions the present invention is concerned with the problem to provide a steel bottle the supporting base of which is formed in one piece with the lower end of the bottle cylinder in a corresponding grip-favouring manner in the region of the domed bottle bottom in the course of the hot flow pressing process.
This probiem is solved according to the present invention substantially by the fact that a) the ratio of support foot thickness to wall thickness of the bottle cylinder amounts to at least 2:1, b) the greatest depth given between the bottle bottom and the standing foot amounts to at least 15% of the outer diameter of the bottle cylinder, and c) the smallest depth between the bottle bottom and the standing foot amounts to at least 9.5% of the outer diameter of the bottle cylinder.
The proposed invention is accompanied by a series of advantages: By means of a manner of construction and configuration occurring in accordance with the teaching of the present invention, a standing foot may now be formed on the bottle by the method of hot flow pressing the depth, or height, respectively, of which ensures satisfactory and above all safe manual manipulation. Thereby risks of accidents which cannot be excluded in the case of standing feet of less deep or high construction, are completely avoided.
In consequence of the unitary construction of bottle body and standing foot, not only an additional as well as also additionally produced constructional component is avoidable, but also the attachment thereof to the bottle body by means of shrinking. Moreover, corrosion effects between the bottle body and the standing foot are completely excluded by the proposed solution.
One constructional example of the invention is illustrated in the drawing. In this case the - single - Figure of the drawing illustrates a vertical section through a steel bottle with a standing foot formed thereon.
The steel bottle which is generally denoted by 1 consists substantially of the cylindrical portion 1 a, the hemispherical portion 1 b with neck 1 c, the neck ring 1 dwhich has been shrunk around the neck 1 c, the hemi-spherical bottom 1 e, as well as the standing foot 1 f.
The wall thickness of the cylindrical bottle portion 1 a is referenced by "s,", the standing foot thickness by "so", the greatest depth between the bottle bottom 1 e and the standing foot If by "t,,,", and the smallest depth between the bottle bottom 1 a and the standing-foot 1 fby "twin", whereas "dA" is the outer diameter of the cylindrical bottle portion 1 a.
Assuming that the wall thickness "s," amounts to 4 mm, according to the teaching of the invention and at a ratio of 1:2 the thickness of the standing foot "s," amounts to 8 mm.
For an - assumed - outer diameter of the cylindrical portion 1 a of the bottle 1 of 140 mm, the greatest depth "that" given between the bottle bottom 1 a and the standing foot 1 amounts to - 1 6% of the outer diameter "dA" or N 22 mm.
In analogy with the two preceding calculation examples, in the application of the teaching of the invention, the smallest depth "twin" between the bottle bottom 1 e and the -- assumd -- outer diameter "dA" = 140 mm of the cylindrical bottle portion 1 a is also determined as at least 10% or 14 mm.
Not last in consequence of the high internal pressure loading of the steel bottle 1, the stated values are minimum values; considerable importance is also attached to the constructional design configuration of the wall transitions by the provision of largest possible radii, for example in order to avoid indentation effects in the regions of relatively great accumulations of material or at the transition from greater to smaller wall thicknesses.
