Definitions

  • the present invention relates to an inflator arrangement.
  • the invention relates to an inflator arrangement 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 on 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.
  • the 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.
  • venturi tubes are often known as venturi airflow guns, which include a venturi tube, namely an air passage with a region of restricted diameter.
  • a venturi tube namely an air passage with a region of restricted diameter.
  • passage of air through the restricted region of a venturi tube creates a low-pressure region resulting in a suction effect used to draw air out of an attached container.
  • known inflator devices are difficult to assembly, operate and not flexible in operation and thus suffer from important limitations.
  • known inflator devices are in the shape of "pistols" which take up space and are difficult to assemble and operate in small and narrow spaces.
  • an inflator arrangement for inflating containers with non- rigid walls such as bags includes
  • a body including inflating means adapted to inflate containers with non- rigid walls such as bags, and having gripping means adapted to assist a user to hold the inflator arrangement; and (b) an enclosure cap member adapted to at least partially enclose the body, and having at least one control member for operating the inflating means.
  • the enclosure cap member may also include holding means adapted to assist a user to hold the inflator arrangement.
  • the enclosure cap member may be a top cover.
  • the arrangement may include locking means adapted to lock the enclosure cap member to the body.
  • the locking means may include a trigger, a trigger lever and a trigger lock.
  • the inflator arrangement may be assembled by positing the enclosure cap member into an upside down position and placing the body also in an upside down position into the enclosure cap member.
  • the body including the inflating means may include
  • the inflator arrangement may include a valve connector assembly attached to the outlet which is adapted to be releasably engaged to a valve.
  • the arrangement may include 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.
  • the arrangement may include sensor means associated with the body and being adapted to indicate the pressure in a container, such as a bag, joined to the body.
  • the arrangement may include a manually operable valve means being adapted cause the supply of compressed air into the air channel to be interrupted.
  • the arrangement may include 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.
  • the arrangement may include a shut-off valve in the container, such as a bag, and being in communication with the air channel.
  • the manually operable valve means may include a ball valve and/or a spring operated trigger valve and/or a shut-off valve.
  • the inflator arrangement may also be used to deflate the containers, whereby the first self-closing valve is removed and/or disabled and the venturi tube is reversed.
  • the sensor means may be adapted to continuously indicate the pressure inside the container whilst the container is being inflated.
  • the inflator arrangement may be a venturi-air flow apparatus.
  • 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 inflator arrangement may be used as a high speed inflator operating at low pressure.
  • the operating pressure of the inflator arrangement 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.
  • the venturi tube may include a frusto-conical bore.
  • the first inlet may be adapted to receive an air hose for supplying compressed air.
