Description

Drum container made of stainless steel

The invention relates to a stainless steel drum container for transporting, storing and holding liquids, in particular of chemicals, with a cylindrical container body having a lid and a bottom, and with a centered in the lid

Container opening, wherein the drum container has a projecting over the container opening annular cover frame.

Barrels made of stainless steel, for example, in the field of catering for filling and germ-free storage of

Drinks used. The reusable ones

Barrel containers, which are also called keg keg or bung barrel, have a cylindrical container body, in whose lid there is a closable container opening. About the container opening of the container body can be filled with a drink, for example with beer. Subsequently, the container opening is closed and the drum container transported to the place where the drink to be stored or kept ready for its removal from the drum container.

To remove the beverage, the container opening is opened again and a nozzle on the container opening

placed. About the nozzle can be a suitable

Propellant such as carbon dioxide or nitrogen in the container to be pressed. When the dispensing nozzle of the pressurized container body is opened, the beverage is forced out of the container body via the dispensing valve.

Such stainless steel drum containers are used not only in the field of catering for the storage and transport of beverages, but also in the field of chemical and pharmaceutical industry for transporting, storing and keeping ready of chemicals and liquid substances. The manufacturer or supplier of the liquid chemicals fills the drum container via the container opening, which is then closed. The filled drum container is transported by the manufacturer or supplier to the consumer and stored there. To be able to remove the liquid chemical from the drum container, the

Consumer the container opening and puts a reusable Multifunktxonsadapter on the open container opening, with the same time propellant

supplied and the pressurized chemical can be removed from the container body. The one for this

required valves are as well as a dip tube and optionally other components in the

Integrated multifunction adapter.

Such cask containers have become a widely used standard and are used by various

Companies offered and used by numerous predominantly commercial consumers. In most cases, on the consumer side specially adapted to the drum containers facilities for storage of drum containers and the removal of the content and provided for use.

Such known from practice barrel container for

Chemicals can be refilled several times and reused. The cleaning of such drum containers is inexpensive and reliable possible. The shape of the container body can be adapted to different volumes and pressure conditions during the removal of the liquid stored therein. The centrally disposed in the lid of the container body

Container opening is regularly sufficiently large

designed to allow easy and quick filling. The container opening can be reliably sealed with simple means to a

Contamination of chemicals and the possible undesirable contact of environmentally hazardous chemicals with the environment reliably avoided. With such cask containers and very sensitive nutrient solutions and high purity liquids can be transported from a manufacturer to a consumer and kept there ready for removal. Contamination of the contents must be ensured even under difficult transport and traffic conditions

Storage conditions can be excluded.

However, it is felt to be a disadvantage that prior to a possible removal of the in the container body

located liquid container opening must be opened and provided with a multi-function adapter. In contrast to the container body has the

Multifunctional adapter regularly on a complex shape, so that the multi-function adapter difficult of Chemical residues or other impurities can be cleaned. In addition, it can not be ruled out that after opening the container opening and before placing and sealing the multi-function adapter contamination of the liquid in the container body by the environment or accidentally by the consumer

he follows. An impurity is in particular in connection with water-sensitive substances and

Solvents feared that even at a

Exclusive contact with moist ambient air can not be excluded.

A drum vessel, as described for example in DE 20 2006 012 195 Ul, does not meet the standards established in practice and is not as

Transport container for transport between one

bottling and a consuming company. Furthermore, this barrel container has a

Multifunction adapter on, so the feared

Disadvantages associated with the use of a

Multifunctional adapter can not be avoided.

In addition, it has been found in practice that as the duration of use increases, the sealing elements used to seal the container opening become leaky. By occasionally occurring deformations of the sealing elements can be a contamination of the liquids in the container body and

optionally an exit from optionally

environmentally harmful vapors are no longer reliably prevented. In a drum container of the type mentioned, as described in DE 20 2006 005 890 Ul, is neither intended nor suitable for the transport and stockpiling of a liquid. Projecting frames are made of rubber, so that a liquid-filled such drum container can hardly be stacked and safely transported due to the weight. An extensive or complete removal during operation as

Water purifier introduced into the barrel container

Liquid is not possible due to the sampling tube running directly below the lid. Of the

Barrel container has no connections that are suitable for a closed removal of products and contamination of a located in the container

Avoid liquid during connection to incoming and outgoing lines. A reusable insert is not possible without the replacement of components, in particular without a new closure for the central container opening. It is therefore considered to be an object of the present invention to provide a drum container of the type mentioned at the outset

To design genus in such a way that the preceding

described advantages in the use of such a barrel container can be maintained while contaminating the contents of the barrel container

can be reliably prevented. It should

be ensured that the essential dimensions of the barrel container are maintained and the connection facilities required for handling as small as possible and changed in a manner that the

Barrel container continues to meet the already established standards and without major modifications in the storage and Terminal devices of the end user can be used by these, making a reusable insert

is relieved. This object is achieved in that spaced from the container opening and spaced

to each other a gas supply opening and a

Liquid removal opening in the lid on the

Container bodies are arranged that the

Gas supply opening a filling valve and the

Liquid removal opening has a removal valve and that the annular cover frame over the filling valve and the extraction valve protrudes. The filling of the container body can be done via the container opening as before. This can then be firmly closed and must not be opened before the liquid can be removed from the container body again. For the supply of the propellant gas and the removal of the located in the container body

Liquid each separate openings are provided. These openings can be a considerably smaller

Have diameter than the filling purposes advantageously large-sized container opening. Since a separate opening is provided for the gas supply and for the liquid removal, the use of a multi-function adapter is no longer necessary. It can be used simple, easy and reliable to clean valves.

To facilitate the handling of the barrel container for the consumer and the gas supply opening and the Fluid extraction opening easily accessible to

Positioning is provided that the gas supply opening and the liquid removal opening are each arranged in the lid of the container body.

The gas supply opening has a filling valve and the liquid removal opening has a removal valve. The filling valve may be configured such that a

Leakage of liquid, which is located in the container body, is prevented by an automatic closing mechanism and the filling valve allows only a filling of the container body from the outside. The liquid removal opening can be closed with a removal valve, which upon actuation of the

Withdrawal valve exclusively a removal of the in the

Container liquid and allows ingress of contaminants from the outside into the

Container body prevented inside. By the arrangement of the filling valve and the

Removal valve in the lid is not only easier to handle, but also a smaller space requirement

allows. In contrast to the known from practice ultimative adapters or valves, which are placed on the central filling opening and above this

Filling opening require space for their arrangement and operation and for the associated connection lines, the filling valve and the sampling valve can be made small and compact and with the associated

Connecting cables are connected. In order to be able to design the drum container in a stackable manner and at the same time be able to protect the filling valves and removal valves arranged in the region of the cover from damage, it is provided that the drum container has an annular cover frame projecting over the filling valve and via the removal valve. In the lid frame handle holes may be arranged to a transport and handling of the drum container to

facilitate. The bottom of the barrel container can be equipped with a matched to the lid frame bottom frame, a positive engagement with the lid frame and thus a simple and reliable stacking several

Drum container allows one above the other. The lid frame and optionally a floor frame as well as the drum container made of stainless steel.

The connection of the associated connection lines is much easier than the arrangement and sealing of a known multi-function adapter. The necessary for a removal of the liquid from the container body

Operations require in contrast to the use of a multi-function adapter in a suitable embodiment of the filling and removal valves no direct access to the container body, or the area of

Filling and removal opening.

To connect a drum container to the associated connection lines for filling the container body with propellant gas and for removing the liquid from the

To facilitate container body is provided that the filling valve or the sampling valve each one

Quick-release coupling device, which at a connection of the filling valve or the extraction valve with an associated connection line opens the filling valve or the extraction valve. Such coupling devices for valves are known in practice. As soon as the associated connection line is connected to the filling valve or to the removal valve with such a quick-action coupling device, the valve is opened and a flow through the valve with the supplied propellant gas or with the liquid forced out of the container body becomes possible. An additional manual actuation of the respective valve is not required.

To be able to avoid contamination of the contents of the drum container during the connection of connecting lines to the filling valve and in particular to the sampling valve is provided that in the filling valve and / or in the sampling valve, a filter device is arranged. The filter device can be used to prevent contamination of the contents of the drum container via contaminated connecting lines. Also can be prevented during the first time

Connecting the drum container to the connection lines provided at a consumer or later via the gas supply opening or the

Fluid removal port impurities or

Moisture can penetrate into the interior of the drum container. With regard to the lowest possible production costs can be provided that the filling valve and the

Extraction valve are substantially identical. There are Appropriate valves known and commercially available, which are equally suitable for liquid and gaseous fluids or can be adapted by the use of suitable seals to different fluids. Such valves can also be designed so that they can be flowed through in an open state only in one direction of the fluid, while a in the

Fluid flowing in the opposite direction closes the valve automatically and prevents the valve from flowing through it.

The filling valve and the removal valve may also have a different design in order to be adapted as best as possible to the respective function. In addition, it may be appropriate that the connection means of

Filling valve and the sampling valve are designed differently to prevent accidental exchange of the respective associated connection lines reliably

to be able to prevent.

It is preferably provided that the

Liquid discharge opening is connected to one end of a dip tube, the other end in one of

Liquid removal opening opposite area of the container body opens. With the help of the dip tube can be ensured that the pressed out of the container body liquid regardless of the respective level always out of the area within the

Removed container body and discharged through the dip tube, in which the dip tube opens, or in which the

Dip tube ends. Advantageously, the liquid removal opening is arranged in the region of the lid of the container body, so that the liquid removal opening opposite end of the dip tube in the region of the bottom of the container body has its mouth opening and out of this area

Liquid is removed.

In order to achieve the most complete removal of the liquid from the container body is provided that the dip tube in a centrally disposed recess in the

Bottom of the container body opens. In the recess whose diameter is smaller than the diameter of the drum, collects during the removal of the liquid, a small residual amount into which protrudes the dip tube, so that further liquid can be removed until the

Level also sinks in the depression so far that it falls below the mouth opening of the dip tube.

Only when a liquid level in the container body into the bottom area, or in the recess of the

Container body drops and almost no liquid is contained in the container body could propellant through the then exposed mouth of the dip tube in the

Dip tube penetrate and thereby a continuous

Remove liquid from the container body.

According to one embodiment of the inventive concept it is provided that the container opening of the drum container can be closed with a seal. Immediately after the

Filling process of the barrel container by the manufacturer, the Befüllungsöff can be tightly sealed and sealed. If the seal were damaged, then one could Manipulation of the contents of the drum or its contamination can no longer be excluded. In contrast, an undamaged seal is a recognized and

Documentable proof that the filling opening is not opened in the meantime and if necessary

was resealed. For special

Safety-relevant applications may additionally be provided that the gas supply opening and ie

Fluid discharge opening or the filling valve and the sampling valve with seals or with a

Tamper evident closures are closed so that even through these openings no access to the in the

Container liquid is possible until the seals or the closures are opened.

An embodiment of the invention will be explained in more detail, which is shown in the drawing. 1 shows a side view of a drum container

The cylindrical container body 2 has a lid 3 and a bottom 4, which are made in one piece together with a lid 3 to the bottom 4 connecting the container wall 5 and form the container body 2. In the container body 2, a container opening 6 is arranged centrally in the lid 3. The diameter of the

Container opening 6 corresponds to about a 1/6 of

Diameter of the cylindrical container body 2. The container body 2 can be filled through the container opening 6 easily and quickly with a liquid or liquid chemical, not shown in the drawing. The container opening 6 is in a filled state of

Container body 2 closed with a closure 7 in order to avoid contamination of the liquid contained in the container body 2 can.

In the lid 3, a gas supply opening 8 and a liquid discharge opening 9 are arranged laterally next to the container opening 6 opposite each other. Of the

Diameter of Gaszuführungsöff 8 and the

Liquid removal opening 9 is each considerably smaller than the diameter of the container opening 6. Die

Gas supply opening 8 is closed with a filling valve 10, while the liquid removal opening 9 is closed with a removal valve 11. The

Filling valve 10 and the extraction valve 11 each have a coupling device 12, 13, by means of which the filling valve 10 and the extraction valve 11 can be connected in a simple manner with an end piece adapted to an associated connection line. When the filling valve 10 and the extraction valve 11 are connected to the associated connection lines, via the gas supply opening 8, a propellant gas as

for example, carbon dioxide or nitrogen in the

Container body 2 are pressed to a

Actuation or opening of the extraction valve 11 to allow liquid to escape from the container body 2.

A dip tube 14 is connected to one end 15 with the

Liquid removal opening 9 connected. Another, the first end 15 opposite end 16 of the dip tube 14 opens in the region of the bottom 4 of the container body 2. About an immediately above the bottom 4 located

Inlet 17, the pressurized liquid can penetrate into the dip tube 14 and through the

Liquid removal opening 9 and the discharge valve 11 exit. In an upright storage of the drum container 1 is ensured via the dip tube 14 that an uninterrupted or undisturbed removal of liquid from the container body 2 is possible until a

Liquid level in the container body 2 so far

has fallen, that the inlet opening 17 is no longer covered by the liquid and propellant gas can escape. The container body 2 is then largely emptied and can then be cleaned and refilled.

In order to facilitate handling of the drum container 1 and to protect the filling valve 10 and the removal valve 11 from damage, the drum container 1 has a protruding in extension of the container wall 5 annular cover frame 18 and a bottom frame 19 adapted thereto. The bottom frame 19 has an inwardly offset, downwardly projecting annular bead 20 on. This bead 20 serves, on the one hand, to give the drum container 1 a reliable and non-tilting base.
