Definitions

  • the present invention relates to a container cover with port. It particularly relates to the design of a lid assembly suitable for adapting to an insulated container for maintaining the contents below 10°C, even while the container is opened frequently at high ambient temperatures while providing for convenient loading of and easy accessibility to the contents. It also relates to a container equipped with such lid.
  • US 5743427 discloses a lid of a container with a discharge aperture in the lid to allow the consumption of a drink through the lid but the discharge aperture area is designed only for fluid food stuffs.
  • WO 9925622 provides a container with a reclosable discharge aperture for food stuffs in particular frozen foods and confections. This invention does not solve the problem of prolonged storage of material under conditions of repeated exposure to high temperature e.g. during vending of foodstuff.
  • a purpose of the present invention is to design a lid assembly for an insulated container provided with economical amounts of the cooling system that allows convenient loading and easy and frequent retrieval of the contents while maintaining the temperature of the contents below 10°C for long enough time periods .
  • It is a first object of the present invention to provide a thermally insulated lid assembly for an insulated container comprising a thermally insulated rotary lid capable of sealing the opening of the inner cavity of the container adapted to hold the objects to be stored therein, the said rotary lid being provided with at least one eccentrically positioned retrieval port and a thermally insulated plug for the said port.
  • the rotary lid can rotate around one axis or more than one.
  • the rotary lid rotates around one axis.
  • the lid assembly is seated on and rotates over a circular opening of the container leading to the inner storage cavity.
  • the rotation of the lid is facilitated by providing advantageous features such as smooth contact surfaces, lubrication, guided ball bearings in a channel, etc.
  • the rotary lid is provided with a fixed or detachable cooling arrangement such as one or more eutectic pads etc.
  • the face of the rotary lid on the inner cavity side can be provided with cooling means such as eutectic/coolant pads and devices to hold them in place. This allows for a further cooling capacity within the container while, in the prior art, where lids, when opened, show the whole container opening, it is not possible to have additional cooling means beneath the lid.
  • the retrieval port provided in the rotary lid is located eccentrically in order to maximise the area swept by the port over the storage cavity and hence provide a better view of the contents and facilitate access to the specific item from the storage cavity.
  • the plug of the port is opened to retrieve the contents during vending.
  • the port can be of any geometrically regular shape such as circular, oval, square, rectangular, triangular or any other irregular shape.
  • the area of the port with respect to the lid is less than 40%, preferably less than 25%, even more preferably less than 10%.
  • the plug may be free, hinged, flippable or otherwise fastened to the rotary lid or the outer part of the container.
  • the lid is transparent. This allows for seeing the inside of the container and rotating the lid in order to have the port above the product to be taken out.
  • the insulated storage container may be designed to have any suitable shape such as a parallelopiped, cube, sphere, cylinder or other attractive geometry.
  • the container can be employed in the horizontal position with the major dimension parallel to the ground or in the vertical position with the major dimension perpendicular to the ground.
  • the mouth and lid can be placed on top of the container or on any of its sides.
  • the container, rotary lid and the plug for the port may be made from any suitable material capable of withstanding low temperatures.
  • suitable materials of construction are low carbon steel, stainless steel, galvanised iron, aluminium, polymeric materials such as high/medium/low density polyethylene, linear low density polyethylene, polyvinyl chloride, polycarbonate, polyester, thermally insulating foams such as polyurethane foam and expanded polystyrene foam etc.
  • the container, rotary lid and the plug of the port can be thermally insulated using polyurethane foam, expanded polystyrene foam, vacuum superinsulation, glass wool, vacuum panels containing powder or open cell polyurethane foam or any other suitable material known in the art.
  • the preferred mode of thermal insulation for the container is multilayer vacuum superinsulation.
  • the vacuum in the annular space between the outer envelope and inner cavity is preferably of the order of 500 Pa or lower.
  • materials such as open cell polyurethane foam, speciality silica, multi-layered sheets of low thermal emmissivity alternating with low thermal conductivity spacer materials etc. may be provided to enhance structural integrity and/or minimise radiative heat transfer.
  • the preferred materials are multi- layered foils of aluminium spaced with thermal insulator or aluminised mylar films.
  • the preferred thermal insulation for the outer rotary lid and the plug to the port is by using polyurethane foam, expanded or extruded polystyrene foam.
  • the insulated container is provided with additional cooling means and preferably a coolant with a heat absorption capacity of >50 joules/gram in the temperature range of 10°C and -80°C.
  • a suitable coolant for the container as well as the rotary lid can be particles of dry ice.
  • sealed pads containing different coolants as specified above can be in the form of bags, arrays of ampoules, bottles, blocks, sachets, blister packs etc. to serve as "coolant batteries" for this purpose.
  • the coolant within the pads may be partially or fully frozen at a low enough temperature.
  • the pads may be loose filled or they can be stacked along the inner surface of the container using a retainer device to improve accessibility of the stored food articles.
  • the coolant pads may also be attached to the surface under the rotary lid.
  • the cooling surface may be provided in the form of pads or jackets fixed to the inner cavity of the container and cooled/frozen in place using primary refrigeration liquid such as R-12, CARE-30 circulated through conduits of appropriate design attached to the coolant pads/ ackets.
  • the source of primary refrigerant may be attached to the container or may be located separately and coupled to the container as and when required.
  • the sealed jackets/pads fixed to the inner vessel may be cooled using secondary refrigerant brines such as aqueous solutions of freezing point depressants or eutectic mixtures of salts in water circulated through conduits of appropriate design.
  • the source of circulating secondary refrigeration brines may be attached to the container or may be located externally and coupled to the container as and when required.
  • the inner cavity of the container may be cooled directly employing primary refrigerant liquid such as R-12, CARE -30 etc. circulated in coils/jackets/conduits of appropriate design.
  • the source of primary refrigerant may be attached to the container or may be located separately and coupled to the container as and when required.
  • the inner cavity of the container may be cooled using secondary refrigerant brines such as aqueous solutions of freezing point depressants or eutectic mixtures of salts in water circulated through coils/jackets/conduits of appropriate design.
