Abstract

A drum (1) of rigid plastics, for bulk storage of lubricants and the like, has drum filling means (5) with a tamper-proof closure (6) and separate liquid dispensing means (14) for one-way dispensation of the drum contents, the dispensing means being also disposed in tamper-proof manner (20, 21) with respect to the drum (1).

Description

DRUM
Workshops , or other small industrial premises, conventionally store lubricants or other chemicals in drums constructed of steel, often with a size of about two hundred litres. These drums have an upper surface with means for filling and dispensing the drum contents. The drums are delivered by the supplier of the lubricant or other chemical and then removed when empty for refilling by the supplier.
There are many disadvantages in this system. Such drums are bulky, especially in the confined space of small workshops. While it is necessary to use a chemicals resistant material, steel is less than ideal in that it rusts and dents, so that the average life of a drum is about three cycles. Even more importantly, the drums need washing out before they can be refilled by the suppliers because of the danger that they have been contaminated on site, by use for storage of alternative materials or simply because of ingress of rubbish such as cigarette butts.
The present invention seeks to provide drums, particularly suitable for use in workshop locations, which overcome these difficulties.
According to this invention we provide, a drum, intended for bulk storage of lubricants or other Iiquid chemicals, substantially of rigid plastics construction and having drum filling means with a tamper proof closure and separate Iiquid dispensing means for one-way dispensation of said drum contents, which dispensing means is also disposed in tamper proof manner with respect to said drum.
The drum is preferably constructed of high density polyethylene, but may be manufactured of altemative materials such as polypropylene dependent on the nature of the contents. It is preferred to use the polyethylene in its natural clear/semi clear state. When natural polyethylene is employed, the drum surface is preferably graduated so that the user can see how much material is left in the drum.
The drums may be of any size suitable for the intended area of use. However, a preferred size is about one hundred litres.
The drum filling means is preferably an aperture in the top surface of the drum fitted with a cap by the supplier in tamper proof manner, for example by crimping on the cap. In this way, the supplier can make sure when he retrieves the drum that the user has not allowed ingress of any foreign matter through the aperture.
The liquids dispensing means is preferably also arranged in the top surface of the drum. It is preferably in the form of a one-way valve to which can be attached a proprietary pump such as a lever pump. The valve is preferably attached to the drum via mating screw threads which are chosen to be unique for that particular drum manufacturer. The valve is preferably used in conjunction with a suction tube which extends down the drum.
The valve is also disposed in tamper proof manner on the drum. This may be done, for example by securing the valve, for example by wiring, to eyes projecting from the drum surface. However, alternative tamper proofing means such as a removable or locking tamper band or other unique fastener could also be used.
The top surface of the drum may conveniently be inset to allow ready nesting of one drum above another for storage. The drums may conveniently be used in conjunction with a dolly for quick and easy movement about the floor of a workshop. While such drums are primarily intended for use for lubricants, they may be used for other chemicals where it is desired to exert tight control over the drum contents. The existence of tamper proofing for both filling and dispensing enables the supplier to exercise complete control and has the benefit of relieving the user from environmental concerns.
One form of the invention will now be described with reference to the accompanying drawing, wherein:
Figure 1 is a diagrammatic representation of the upper portion of a drum to which a dispensing pump has been attached.
Figure 2 is a cross section through the one-way valve shown in Figure 1.
The drum 1 , shown in Figure 1 is constructed of natural clear polyethylene.
The drum surface carries gradations (not shown) to indicate the filling level of the drum. The upper surface 2 has cylindrical protrusions 3 and 4.
Protrusion 3 defines a filling aperture 5 for the drum contents. It is fitted with a crimped tin plate seal 6.
The cylindrical protrusion 4, also shown in Figure 2, is internally screw threaded to receive a one-way valve generally indicated at 7. While the one-way valve may be of any design, suitably, it is externally screw threaded at 8 to match the internal screw thread of protrusion 4. The valve 7 comprises an upper cup portion 10 with a inner cup 11. The external surface of the inner cup and internal surface of the upper cup 10 are threaded at 12 and 13 respectively to receive respectively a connector 22 for connection to an air pump (not shown) or a standard lever pump 14 fitted with an optional locking device 15. The one way valve 7 also has a lower cup 16 internally threaded at 17 to receive a suction tube 18 extending to the region of the bottom of the drum.
The upper surface of the drum surrounding the cylindrical protrusion 4 has a series of radially disposed eyes 20 from which wires can extend for connection to eyes 21 on the exterior of the upper cup 10 of the one-way valve.
It is possible to use the lever pump 14 or an air pump with the one-way valve.
The drum shown in the figures has several advantages. The clarity of the polyethylene allows the user to see clearly the fill level of the contents. The material of the drum is robust. Thus it has been found in practice that such drums can be used for fifteen to twenty round trips between supplier and user.
The provision of a built in suction tube spares the user from the messy job of attaching a valve and suction tube arrangement to the drum as supplied by the supplier to his workshop. The double tamper proofing for both filling and delivery ensures that the user has passed environmental control of the drum to the supplier. Conversely, the supplier knows that the drum has not been tampered with and can refill in confidence without laborious and costly washing procedures.
