Definitions

  • the present invention relates to systems for the transport of liquid goods in general, and in particular to systems for transporting hazardous liquid goods, in particular organic peroxides, under refrigerated conditions.
  • Liquid goods, and in particular hazardous liquid goods such as organic peroxides are usually kept in containers of small nominal capacities like for instance jerrycans holding 20 l, 30 l, 50 l or the like. Distributing larger quantities of a liquid among several individual containers reduces the sloshing amplitudes of the liquid during shipment as compared to the entire liquid being received in one big container only, and thus minimizes the risk of any build up of uneven weight distributions during transport.
  • the nominal capacity of an individual container is generally somewhat smaller than its actual volume to allow for gases possibly developing from the liquid held therein to be received in the excess volume without any build up of excessive pressure that would jeopardize the transport.
  • the basic element of a respective system is a container whose outer dimensions provide an optimum utilization of a reefer's loading space while further providing for a buffer zone large enough to allow for a possible bulging of the container when filled and clearances needed for safely placing the containers inside the reefer's loading space.
  • weight shifts along its short side direction have a greater impact on a transport vehicle's stability than longitudinal shifts, i.e. weight shifts along the reefer's lengthwise direction.
  • the small clearances also ensure that a shifting cargo will not gain enough kinetic energy to endanger the stability of the transport means.
  • the containers For enabling a loading and unloading of the reefer with conventional forklifts, the containers should be arrangeable in unit loads whose lateral maximum dimensions do not exceed 1500 mm.
  • the containers should furthermore not be designed too slim in order to avoid them being tipped over accidentally.
  • the short side of a container should therefore not be less than about half the container's height.
  • the liquid holding capacity of a container could be for example 30 l, 25 l or 20 l.
  • the height of a container is, for a given holding capacity and a prescribed additional volume, a function of its lateral dimensions, it should be designed to make a maximum use of the reefer's usable loading space height, which is 2500 mm, leaving some space in the reefer for lifting the unit loads upon loading and unloading and permitting the circulation of cooling air inside the reefer.
  • a liquid container in the form of a jerrycan designed to fit in an individual cargo space having a length of 380 mm, a width of 250 mm, and for example a height of 440 mm (nominal capacity of 30 l), a height of 365 mm (nominal capacity of 25 l), or a height of 310 mm (nominal capacity of 20 l).
  • the actual lateral dimensions of the jerrycan are of course somewhat smaller to allow a bulging of the jerrycan's sidewalls when filled to their maximum capacity.
  • the term “jerrycan” is used in this document in conformity with the European Agreement concerning the International Carriage of Dangerous Goods by Road and refers to a metal or plastics packaging of rectangular or polygonal cross-section with one or more orifices.
  • the invention relates to a liquid container, in particular for transport under refrigerated conditions, having sidewalls connected to each other by rounded edge portions, wherein the main faces of adjacent sidewalls are generally perpendicular to each other;
  • the top sidewall comprises at least one recessed portion containing an orifice adapted for being closed by a cap in a form fit and at least one handle above the bottom of the recess, the top of the handle being either flush with the main face of the top sidewall or located beneath it; and wherein the main faces of the liquid container define a rectangular cuboid geometry having a width of less than 250 mm and a length of less than 380 mm.
  • jerrycans By filling the loading space of a reefer with such jerrycans, six cans can be stored along the short side of the reefer and twenty cans along the long side of the reefer, with the length of the jerrycans aligned in parallel with the short side direction and the width of the jerrycans aligned in parallel with the long side direction of the reefer.
  • the unused spaces or clearances in the container will then amount to 20 mm along the reefer's width and to 42 mm along the reefer's length, and are thus within the limits described above.
  • a liquid container forming the basic element of a refrigerated liquid transport system as specified above comprises sidewalls connected to each other by rounded edge portions, whereby the main faces of adjacent sidewalls are generally perpendicular to each other.
  • the top sidewall of a respective liquid container comprises at least one recessed portion containing an orifice adapted for being closed using a cap.
  • the closure is implemented in a form fit manner to allow the orifice to be opened and closed repeatedly.
  • the top sidewall further includes at least one handle located above the bottom of the recess allowing the liquid container to be carried by a person.
  • the top of the handle is either flush with the main face of the top sidewall or located beneath it, so that the bottom sidewall of a liquid container of the same kind can steadily rest on the liquid container's top sidewall.
  • the main faces of the liquid container define or form part of a rectangular cuboid geometry having a width of less than 250 mm, a length of less than 380 mm, and a height of for example about 440 mm for a nominal 30 l capacity, a height of about 365 mm for a nominal 25 l capacity, and a height of about 310 mm for a nominal 20 l capacity. It will be apparent to one having ordinary skill in the art that the height of a liquid container can easily be adapted to the nominal capacity desired for the container.
  • main face is hereby used to refer to that part of a sidewall that defines a face of a rectangular cuboid representing the storage volume occupied by the liquid container.
  • generally perpendicular includes angles ranging from 80° to 100°.
  • a liquid container having features as specified above can be filled up to its nominal capacity, i.e. with up to 30 l, 25 l or 20 l of a liquid, whereby the liquid will then occupy about 90%, in some cases up to 94% of the space enclosed by the container.
  • the volume not used by the liquid can receive gases released from the liquid, thereby reducing the risk of excessive pressure building up in the container.
  • the term “refrigerated” is understood to mean conditions that enable a desired temperature of a product to be maintained. Said temperature is preferably between ⁇ 30° C. and +30° C.
  • the liquid container as defined above comprises at least one organic peroxide.
  • said liquid container comprises a liquid comprising and consisting of at least one organic peroxide.
  • Said at least one peroxide may be pure or present in an organic or aqueous solvent.
  • a further element of a refrigerated liquid transport system as specified above is a pallet providing a loading area of 1200 to 1300 mm in length, preferably of 1230 to 1270 mm in length, preferably of 1240 to 1260 mm in length and more preferentially of 1250 mm in length and of 710 to 810 mm in width, preferably of 740 to 780 mm in width, preferably of 750 to 770 mm in width and more preferentially of 760 mm in width.
  • the height of the pallet is preferably 100 to 200 mm, preferably 130 to 170 mm, preferably 140 to 160 mm and more preferentially 150 mm allowing the pallet to be handled with conventional forklifts.
  • liquid containers are placed on the pallet side by side in a way that the containers cover the pallet's loading area.
  • the liquid containers are preferably fixed on the pallet using e. g. a stretch wrap or stretch film.
  • a side by side arrangement of liquid containers covering an area corresponding to the loading area of the above pallet is in the following referred to as a layer of liquid containers.
  • Other forms of unit loads have two or more layers of liquid containers placed on the above defined pallet, in particular two, three or five layers.
  • unit loads with up to 5 layers of liquid containers placed on an above defined pallet can be formed.

  • the main face 301 ′ is formed by the outermost top surface of the top sidewall 301 , whereby possible protrusions 311 extending from the top main face 301 ′ are not taken into account.
  • the top main face 301 ′ has a U-shaped form, surrounding a recessed part 315 of the top sidewall.
  • the top sidewall 301 is configured with an orifice 312 and a handle 313 .
  • the orifice 312 is preferably located close to the front edge 304 ( f ) forming the transition between the top and the front sidewall. This enables a complete emptying of the container 300 .
  • Embodiments have the orifice 312 configured to cooperate with a closure (not shown in the Figures), for instance a screw closure like a screw cap or screw plug.
  • Other embodiments have the orifice configured to cooperate with a bayonet cap.
  • the orifice is disposed in a recess 315 .
  • the orifice is part of a spoutlike nozzle, the height of which is lower than the depth of the recess 315 , i.e. the vertical dimension of the recess.
  • the handle 313 is disposed above the bottom of the recess 315 with one end of it merging into the rear face of the recess 315 , and the other end forming a mechanical link to the bottom of the recess 315 near the nozzle providing the orifice 312 .
  • the handle is equally spaced from the side faces of the recess 315 and there is some clearance between the handle and the bottom of the recess.
  • protrusions 311 may be formed in the top main face 301 ′.
  • the protrusions 311 extend vertically from the top main face 301 ′ but are not part of that face, since they are to be received in complementarily designed recesses (not visible in the Figures) formed in the bottom main face of a container 300 placed on the top main face 301 ′, and therefore do not contribute to the storage volume occupied by the liquid container 300 .
  • the protrusions 311 together with the recesses of a container 300 placed on top, the protrusions 311 form a form fit preventing a lateral movement of the upper container relative to the lower container.
  • the protrusions usually have a frustumlike shape, i.e. a tapered geometry with a polygonal or round base and a corresponding polygonal rounded top face of smaller dimensions.
  • the main faces 303 ′ may be oriented vertically for a container 300 being placed on a horizontal area. One face or all of them may also be slightly inclined so that the circumference of the container 300 decreases towards its top sidewall. In this case, the respective sidewall or sidewalls do not form part of the rectangular cuboid geometry defining the storage space needed for the empty container 300 . The dimensions of the rectangular cuboid geometry are then defined by the outermost limits of the respective main face(s).
  • the dimensions of the rectangular cuboid geometry are thus, that its width is within a range from 225 mm and less than 250 mm, its length within a range from 360 to less than 380 mm and its height 440 mm or slightly less (30 l capacity), 365 mm or slightly less (25 l capacity), or 310 mm or slightly less (20 l capacity).
  • the term “slightly less” is to be understood as not more than 5 mm.
  • the length of the rectangular cuboid is advantageously in the range from 364 mm to 372 mm, preferably in the range from 366 mm to 370 mm, and is ideally 368 mm, and wherein the width of the rectangular cuboid is in the range from 228 mm to 234 mm, preferably in the range from 239 mm to 233 mm, and is ideally 231 mm.
