Definitions
- the present invention relates to an inflation device.
- the invention relates to an inflation device for inflating containers with non-rigid-walls, such as dunnage bags
- dunnage bags are commonly used for cushioning loads shipped in trucks, trailers and containers transported by ships, trucks or rail. This is often the case when the cargo only partially fills the container and there exists the possibility of shifting during transport that could cause damage.
- dunnage bags are constructed of one or more layers of paper or woven polypropylene surrounding a plastic lining. The paper protects the bags from tearing - thus more layers are used in applications where the risk of damage to the dunnage bag is greater.
- a valve is attached by way of a hole cut in the bag during manufacture.
- dunnage bags are shipped flat from the manufacturer, and are inflated by packing and loading personnel as the containers are loaded with cargo.
- the bag is firstly placed in the space that it will occupy as cargo is loaded into a container, secondly the inflation device is attached to valve of the dunnage bag and subsequently the dunnage bag is filled with air until an appropriate air pressure within the bag is achieved. Typically this occurs within a few seconds.
- Various types of inflation devices exist for inflating containers with non-rigid walls and air-filled bags, such as sacks and dunnage bags commonly used to cushion cargo loads.
- Known inflation devices include tire inflation tools which have been converted or adapted and are attached to a hose leading from a source of compressed air.
- Some inflation devices incorporate venturi tubes and are often known as venturi air-flow guns, which include a venturi tube, namely an air passage with a region of restricted diameter.
- venturi air-flow guns which include a venturi tube, namely an air passage with a region of restricted diameter.
- PCT/IB2009/050851 STOPAK (PTY) LTD et al discloses an inflation device for inflating containers with non-rigid walls such as bags, which includes a body having a venturi shaped air channel. First and second air inlets lead into the air channel, with an outlet being adapted to allow air to exit from the air channel for inflating a container when joined to the outlet. The second inlet is adapted to be closed by a self-closing valve if air does not flow through the air channel.
- a sensor associated with the body is adapted to detect when a container, such as a bag, joined to the body has been filled to a predetermined degree and then causes the flow of air through the air channel to be interrupted automatically.
- this inflation device is expensive and requires electricity and batteries to operate which often are not available at the sites where dunnage bags are inflated.
- an inflation device for inflating containers with non- rigid walls such as bags includes
- a first self-closing valve located at the second inlet in the body and being adapted to close off the second inlet if the pressure in the air channel is greater than the ambient pressure
- a sensor means associated with the body and being adapted to indicate the pressure in a container, such as a bag, joined to the body;
- a manually operable valve means being adapted cause the supply of compressed air into the air channel to be interrupted .
- an inflation device for inflating containers with non-rigid walls includes
- a first self-closing valve located at the second inlet in the body and being adapted to close off the second inlet if the pressure in the air channel is greater than the ambient pressure
- a shut-off valve in the container, such as a bag, and being in communication with the air channel;
- a sensor means associated with the body and being adapted to indicate continuously the pressure in a container, such as a bag, joined to the body;
- a manually operable valve means being adapted cause the supply of compressed air into the air channel to be interrupted.
- a method of inflating containers with non-rigid walls, such as bags includes the steps
- the manually operable valve means may include a ball valve and/or a spring operated trigger valve and/or a shut-off valve.
- the inflation device may also be used to deflate the containers, whereby the first self closing valve is removed and/or disabled and the venture tube is reversed.
- the sensor means may be adapted to continuously indicate the pressure inside the container whilst the container is being inflated.
- the inflation device may be a venturi-air flow apparatus or gun.
- the venturi tube may include a supersonic nozzle.
- the air exiting the outlet may have an absolute pressure of about 0 to 9 bar.
- the compressed air entering the air channel may have a pressure of up to 9 bar absolute.
- the supersonic nozzle may be a shock-free type.
- the inflation device may be used as a high speed inflator operating at low pressure.
- the operating pressure of the inflation device may be about 9 bar absolute.
- the body may have a flange for securing the inflation valve to the container.
- the container may be a dunnage bag, a sack and/or any other flexible container to be pressurized.
- the body may include threads suitable for cooperating with complementary threads of a container's inlet.
- the device may include a valve connector assembly attached to the outlet of the air channel, which is adapted to be releasably engaged to a valve.
