Definitions

• the invention relates to a drum, comprising a side wall, a bottom and a top wall, which bottom and top wall are connected by
• a * a folded joint to the side wall, and in which the top wall is provided with at least one closable aperture with a neck going out 5 from an outward-pressed part surrounding the neck, which top wall inwards from a circle in the plane of the top wall is curved in ⁇ wards and outwards from said circle has an edge strip, all this in such a way that in the inverted position of the drum the contents can run off through the aperture.
• Such a drum is known from, for example, German Gebrauchsmus- ter G 87 09594.7.
• the curvature and the conical surface shaped edge strip intersect each other approxi ⁇ mately at the centre lines of the apertures, so that these inter ⁇ sections form a valley which runs round in the peripheral direction
• This known drum was designed because the chemical industry has now set the condition for drum manufacturers that a drum, such
• a drum with an entirely flat top wall which is provided in the known manner with two apertures, also meets this condition, but a drum with such a flat top wall also has the problem of not being strong enough. Internal excess pressure can lead to permanent deformation. The curvature, as in the case of the above-mentioned known drum, does not have that problem.
• a disadvantage of the known drum is, however, that the re ⁇ maining liquid has to drain off through the small aperture, while in general there is a requirement that this must take place through the large aperture. It is possible to place the large aperture lower down than the small one and to make the groove of the small one slope towards the large aperture.
• the top wall in order to prevent the large closure from projecting beyond the edge of the drum, the top wall must be made of a greater depth. A considerably greater quantity of mate ⁇ rial is required for this.
• the object of the invention is then to provide a drum which meets the requirement set, remains simple to manufacture, and is strong enough.
• the circle surrounding the inward curvature has a diameter which is greater than the largest circle " within which the edge of the outward-pressed part surrounding the neck facing the folded joint is situated, but is smaller than the diameter of the inside face of the wall of the drum, so that an edge strip is formed between said curvature and the drum wall, and in that at this aperture the top wall has a strip which from the edge strip faces away from the drum wall, and which surrounds the outward-pressed part at least partially, and forms a small angle with a horizontal face lying at right angles to the centre line of the drum, in such a way that in the inverted position of the drum with the aperture downwards this strip forms a run-off face running from the edge strip in a down ⁇ ward slope.
• Fig. 1 is a top view of a part of the top wall of a drum.
• Fig. 2 is a cross-section through the top wall of the drum of Fig. 1, but where the drum is placed on its head.
• Fig. 3 is an enlarged cross-section through the righthand part of Fig. 2.
• the figures show a part of a drum with a drum wall 1 and a _ top wall 2.
• Fig. 2 shows the drum placed on its head, so that the top * 35 wall 2 is facing the ground surface 3 and rests on it with the folded joint 4, by which top wall 2 and drum wall 1 are connected to each other.
• a closable filling aperture 5 and a closable vent aperture 6 are situated in the top wall. These apertures are formed by bushes
• the top wall 2 is pressed inwards over virtually its entire surface with a large radius, so that an inward curvature is formed, which in the inverted position shown in Fig. 2 forms a run-off face ending at 10, at a short distance from the inside wall of the drum.
• a narrow edge strip 11 for example 8 mm wide, is left between the outside edge of the inward-curved part and the inside wall of the drum 1, said strip being essentially flat, i.e. runs horizontally and can have only a small gap 12 determined by the folded joint finish where the top wall connects to the drum wall.
• the top wall In order to reinforce the top wall, it can have various stepped slopes, such as the slope 13, 14.
• a run-off strip 15 running from the edge strip 11 and sloping at a slight angle, which is more clearly visible in Fig. 3.
• This run-off strip 15 runs from the edge strip 11, in the inverted position shown in the drawing, slanting downward at a slight angle, at least to the face 16 in which the flange of the bush 7 is situated.
• This run-off strip can also be surrounded by a sloping, for example U-shaped edge 17 running from the edge strip.
• Liquid will then remain behind at most in the gap 12, insofar as present, for it can also be filled up with an internal lacquer coating or the like. In any case, what liquid could remain behind is less than the earlier mentioned conditions.
