Abstract

A closure device 1 for the sealing closure of a container, in particular an oil or chemical drum, has a recess which projects into the interior of the container. The recess may contain accessories such as valves, drainage aids and tools. The recess may have a round, oval or rectangular shape and be tapered or widened in the direction of the interior of the container. The recess may also be provided with a lid e.g. in the form of adhesive tape which at least partially cover the recess. In addition, the recess may be compartmentalised and it may have means for receiving the accessories such as clamping means. The container closure is preferably provided with at least one and preferably two openings which may be for emptying and/or venting the container. Ideally, the recess allows accessories to be safely stored without affecting the stackability of drums.

Description

2320483 DescriT)tion Closure device

The Present invention relates to a closure device for the sealing closure of a container in accordance with the preamble of Claim 1.

In the past, various lid structures or closure devices were used for the sealing closure of a container. For example, a snap lid is known which is, as a rule, pushed over the outer rim of the container and seals the container because of its elasticity.

In addition, countersunk lids having cylindrical flange are known, such as those used, for example, to seal paint tins or other chemical containers.

Closure devices in the form of a circular lid for drums of all kinds are likewise known, the lid engaging by means of a closure clamping device which engages at the upper rim of the lid and at a projecting rim of the container situated opposite and seals the container by clamping in the circumferential direction.

In the case of drums, the lid frequently has preferably threaded openings through which a liquid content can be discharged, as a rule through the larger opening, the smaller opening simultaneously serving to equalize the pressure. Frequently, special accessoo'ries are needed which may comprise, for example, tools for unscrewing the drums and/or draining devices, stopcocks or the like in order to empty the drums properly. Since different standards on threads and bore diameters etc. frequently exist in different countries, it has become the custom that many chemical producers and petrochemical companies 2 supply their clients with the accessories along with their drums.

In the past, this was done. on the one hand, by means of separate accessory packages which were delivered together with the drums, which frequently resulted, however, in such separate parts being lost or interchanged so that said accessories then frequently had to be reordered, as a result of which a not inconsiderable time loss arose.

Furthermore, it is also not possible for practicability reasons to attach accessories to the side walls of the drums, for instance by means of adhesive strips, because this would impede the rolling of the drums over short is paths for the purpose of transportation and/or the accessories would be damaged.

On the other hand, the accessories were in some cases stuck directly to the lid of the drums by means of an adhesive tape. This likewise frequently resulted, however, in these parts being torn off and being lost during the transportation and, on the other hand, the stuck-on accessories impeded the stacking of the individual containers, in particular drums, on top of one another, which frequently resulted in unacceptable safety risks so that such drums could only be stacked alongside one another, which, conversely, had the consequence in turn that high transportation costs arose which had to be passed on to the end user.

Proceeding from this prior art, the object of the present invention was therefore to provide a possibility of arranging the accessories needed for specific containers safely on the container, the stackability not being impaired.

Claims

This object is achieved by the characterizing features of Claim 1.

According to the invention, a closure device for the sealing closure of a container is provided, wherein the closure device has a recess which projects into the interior of the container.

The accessory material is then arranged in said recess, for example by clamping in, sticking on, screwing on or the like so that the accessories do not project beyond the surface of the closure device, in particular the lid. As a result, the stackability of the containers, for example the drums, is not impaired.

Preferably, the recess may contain as accessories valves, drainage aids, tools or the like.

The closure device according to the invention is 20 particularly suitable for closing drum-type containers, in particular for sealing lubricant drums.

The recess may have a round, oval, rectangular or parallelepiped shape and may, if necessary, be tapered or widened in the direction of the. interior of the container in order thereby to be matched optimally to the accessories to be received.

Particularly preferably, the recess itself may have a lid 30 which prevents small parts being, lost on the transportation route.

Such a lid may comprise, for example, also adhesive tape which partially covers the recess.

In addition, it is advantageous if the recess is compartmented, that is to say it contains a plurality of 4 chambers into which various materials and/or accessory parts, such as screws, seals, tools, etc., can be introduced. The recess can also have means for receiving the accessory; such as, for instance, clamping devices.

Further advantages and features emerge from the description of an exemplary embodiment of the invention and also from the drawing.

In the drawing:

Figure 1: shows a cross section through a closure device according to the invention; Figure 2: shows a closure device according to the invention as a lid on a lubricant drum; Figure 3: shows a plan view of a closure device according to the invention.

In Figure 1, 1 denotes a closure device according to the invention, in the exemplary case the lid of a lubricant drum. The recess 2 oriented in the direction of the interior of the container is of conical design in the 25 exemplary case.

Situated in the interior 3 is the accessory 4, in the exemplary case a tapping cock.

Figure 2 shows the arrangement of the closure device 1 on a lubricant drum 5.

When the lubricant drum 5 is closed in a sealing manner with the lid 1, the recess 2 projects into the interior 6 of the lubricant drum 5.

Situated in the interior 3 of the recess 2 is the accessory 4. The recess 2 may, but need not, dip below the surface 7 of the lubricant in the interior 6 of the lubricant drum 5.

Figure 3 shows a plan view of the closure device according to the invention. In addition to the recess 2, which contains the accessory 4 in its interior, the closure device 1 has a screwable opening 8 which serves, for example, as venting opening. In addition, the closure device 1 likewise has a screwable drainage opening 9 into which the tapping cock can be screwed as accessory 4.

As a result of the present invention, accessories of all types can be safely arranged in the interior 3 of the recess 2 so that, on the one hand, they no longer get lost and, on the other hand, the containers, in the exemplary case lubricant drums, can be safely stacked without the accessories impeding the stacking.
