Abstract

1490487 Blow moulded barrel MAUSER K-G 8 July 1976 [4 Oct 1975] 28423/76 Heading B5A [Also in Division B8] A barrel of plastics material is formed with an outwardly extending peripheral flange 6 of solid section and of a thickness greater than the barrel wall adjacent the barrel opening, by blow moulding a tube between mould halves 2, 3, Fig. 1, to form the wall of the barrel into an outwardly projecting hollow rib 4 and then, whilst the wall is still plastic, displacing the mould halves 2, 3, towards each other to collapse the axially opposite walls of the rib 4 together to form the rib into the flange 6. The blow moulded barrel is moulded with a corrugated neck portion 5, from above which blow moulded material is cut away to form the barrel opening. The flange 6 is outwardly tapered, between lower and upper surfaces which are respectively inclined to and at right angles to the barrel axis. The barrel is closed by a lid 11 sealing to the top of the neck 5 at a seal 17, and having an inner skirt 13 contacting the neck 5 and an outer skirt 14 terminating at an outwardly extending flange 15, at which the lid is clamped to the flange 6 by a ring 16.

Description

The present invention relates to a blow-moulded plastics barrels.
Plastics barrels are known in v/hich an outwardly-extending peripheral rib is rmed at a distance below the barrel opening. This rib acts as a peripheral bead, a opening is closed by a plastics lid which is dished to fit into the barrel openg. The lid also has a depending skirt terminating in an outwardly-extending jnge which may be clamped to the bead by a clamping ring.
Under vertical stacking loads of the kind which occur when several filled -rels are stacked one upon each other the peripheral bead is irregulaly compressed, isequently, the barrel stack may topple and the lid may become unsealed.
It is known to reinforce the peripheral ribs by forming inwardly-directed jhts, i.e. indentations from the outside of the rib, uniformly distributed along • circumference of the rib. Axial compression of the rib is thus substantially minated.
A disadvantage of the indentations is that they reduce the radial stiffness the barrel rib, and also the parts of the rib between the indentations hold idents after the barrel is emptied.
The invention provides a method of forming a plastics barrel by blow moulding, luding the step of blow moulding the wall of the barrel into an outwardly-extendperipheral rib adjacent a corrugated neck portion, the rib being defined interny between opposed wall surfaces and being collapsed while plastic so as to bring -2the opposed wall surfaces together to form an outwardly-extending peripheral flange adjacent the corrugated neck portion, the flange having a greater thickness than the wall.
The invention further provides a plastics barrel formed by the above-described method.
An embodiment of the invention will now be described with reference to the accompanying drawings, wherein: Figure 1 shows in longitudinal section part of the barrel during forming of the peripheral rib, Figure 2 is a similar view to Figure 1 but with the fold compressed to form a flange, and Figure 3 shows in longitudinal section part of the upper end of a barrel with a lid mounted thereon.
In Figure 1 a barrel wall has been blow moulded in two mould halves 2 and 3 so as to form an outwardly-extending peripheral rib 4. The rib 4 is spaced from one end of the barrel by means of a corrugated neck portion 5.
While the material of the barrel wall is still plastic, the two mould halves 2, 3 are moved axially towards each other in the direction of the arrows 18 in Figure 1 so that the rib 4 is collapsed to form an outwardly-extending flange 6 (Figure 2).
As can be seen from Figure 2, the flange has an upper peripheral surface 7, which extends outwardly at right angles from the longitudinal axis of the barrel, and a lower peripheral surface 8, which is inclined to the longitudinal axis of the barrel so that the cross section of the flange 6 decreases in an outwards direction.
The barrel wall 1 is removed from the mould and cut along a line 9 to form an open end 10. As can be seen from Figures 2 and 3 the peripheral flange 6 is considerably thicker than the barrel wall 1.
In Figure 3, the open end 10 is closed by a lid 11, which has a dished portion 12 fitting inside the open end 10. The lid 11 has an inner denending peripheral skirt 13, which contacts the inside of the neck 5. The lid 11 ηΐκυ baa an outer depending peripheral skirt 14, which surrounds the outside of the neck 5 and terminates in an outwardly extending peripheral flange 15. The flange 15 is clamped to the flange 6 by means of a clamping ring 16. A deformable seal 17 has -3>een inserted between the top end of the barrel neck 5 and that part of the lid 11 between the skirts 13, 14.

Claims (10)

1. A method of forming a plastics barrel by blow moulding, including the step of blow moulding the wall of the barrel into an outwardly-extending peripheral rib adjacent a corrugated neck portion, the rib being defined internally between opposed wall surfaces and being collapsed while olastic so as to bring the opposed wall surfaces together to form an outwardly-extending peripheral flange adjacent the corrugated neck portion, the flange having a greater thickness than the wall.
2. A method as claimed in claim 1, wherein the blow moulding is performed in two mould halves which are then moved towards each other along the barrel axis to collapse the rib.
