RELATED TECHNICAL FIELD

This invention relates to an air discharge nozzle providing air to escape during the discharge by positioning at the orifice portion of the structures used in the storage and transportation of the liquids such as barrels, drums and cans.

STATE OF THE ART

Structures such as cans, barrels and drums are usually large-sized structures in which the liquids are filled.

There are orifices at the top-upper portions of these structures to fill and discharge liquids.

During the discharge of the liquids, cans and barrels should be tilted in a way that their orifice is downwards. Although there are currently means for said tilting procedure, usually cans are lifted and tilted with manpower. As cans, barrel and drums are large-sized and large-volumed structures, they become very heavy when they are filled with a liquid. Therefore, it becomes very hard to control the cans while discharging either by means for tilting and lifting the cans or by manpower.

Due to their weight, the liquid comes out intensely out of the orifices of the cans during the discharge and thus the air and the liquid are unable to replace in a balanced manner, causing the liquid to overflow and splash onto the surroundings. This situations occur over and over again particularly in the discharge operations where a stop-discharge movement is required for using liquids for a mixture.

This causes the liquid substance to be wasted by overflowing onto the surroundings during the discharge. On the other hand, in case the liquid substance is a harmful chemical, spreading of the liquid in the surrounding constitutes a risk both for the persons performing the discharge and the environment.

In the standard can, drum and barrel structures, the reason why said overflowings and splashes happen is that the orifice portion of these structures cannot provide a balanced air circulation during the discharge. In order to eliminate said disadvantages of the structures such as cans, barrel and drums, tap structures were incorporated to the cans, barrels and drums. However, the taps may get deformed over time and their connection parts may get loose. Additionally clogging may occur in the taps over time depending on the properties of the liquid.

Another method to provide an air circulation during the discharge is cans with orifice constructions that have separate inlet and outlet channels for air and liquid.

In the construction with said separate channels, when the outlet for air circulation and the outlet for the liquid discharge are not adjusted properly, the liquid may come out of the air outlet.

These other structures are currently produced as one-piece articles with the can. In order to produce structures with said one-piece constructions, separate molding and manufacturing processes should be performed for each size of the cans. On the other hand, said orifice construction is provided only in the cans of 20-30 liters.

OBJECT OF THE INVENTION

One object of this invention is to prevent the liquid from spreading and splashing onto the surroundings by providing air discharge from these structures during the discharge of the liquid from the structures containing a liquid, such as cans, barrels and drums.

Another object of this invention is to provide a balanced, fluid and rapid discharge by providing air discharge from these structures during the discharge of the liquid from the structures containing a liquid, such as cans, barrels and drums.

DESCRIPTION OF THE INVENTION

The air discharge nozzle (1) of the invention has a structure that prevents the liquid from spreading and splashing onto the surroundings during the discharge from the can and provides an air circulation to provide a balanced and fluid discharge; and comprising a liquid outlet section (1.1) forming the section where the liquid comes out; an air channel (1.2) discharging the air in the can; and a fixing edge (1.3) allowing fixing the air discharge nozzle (1) to the can orifice in a sealed manner.

The air discharge nozzle (1) is fixed to the orifice portions of the structures such as cans, barrels and drums. After the air discharge nozzle (1) is fixed, the liquid discharged from the can comes out of the liquid discharge section (1.1) of the air discharge nozzle (1).

During the discharge of the liquid, the air channel (1.2) provides an air circulation. The air channel (1.2) extends downwards from the can orifice. The air in the can goes in through the lower gap of the air channel (1.2) extending downwards and goes out of the upper gap of the air channel (1.2). In this way, the air is discharged from the can and a balanced and fluid discharge of the liquid is provided.

The air discharge nozzle (1) of the invention has a liquid outlet section (1.1) which is 1.5 times larger the air channel (1.2).

The air discharge nozzle (1) of the invention can be produced with a mold in a one-piece manner. In the example of the invention, an air discharge nozzle (1) with a one-piece body of polypropylene (PP) is used.

The air discharge nozzle (1) of the invention can be applied to all liquid storage and transportation structures such as cans, barrels and drums with a capacity of 3 liters to 200 liters. The air discharge nozzle (1) can be produced with various diameters which are suitable for the orifice diameter of the can on which it is to be used. The air discharge nozzle (1) of the invention can be inserted at the can orifices during the production of the cans. In this way, there will be no need to insert and remove the air discharge nozzle (1) from the can.

In addition to being inserted to the can orifices during the production of the cans, the air discharge nozzle (1) can be fixed to the cans that are already in use. The air discharge nozzle (1) is fixed to the orifice of the can by nailing. In this way, the air discharge nozzle (1) body is located in the orifice of the can and the fixing edge (1.3) is fixed in a sealed way by fitting around the orifice of the can.
