DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

(8) The container 10 shown in FIG. 1 is formed from the blank 100 shown in FIG. 2 in the manner set out in FIGS. 3 to 5. The container 10 is used to reduce deterioration of horticultural produce. The container 10 includes a parallelogram base member 12; first and second parallelogram side members 14a, 14b, each extending substantially normally from respective opposed sides 16a, 16b of the base member 12. The container 10 also includes first and second parallelogram end members 18a, 18b, each extending substantially normally from respective opposed ends 20a, 20b of the base member 12. Further, the container includes four webbings 22a, 22b, 22c, 22d coupled between neighbouring end sections 23 of side members 14a, 14b and end members 18a, 18b.

(9) Each webbing 22a, 22b, 22c, 22d includes inner and outer triangular sections 24a, 24b having a common apex 26 at the base member 12. The inner triangular section 24a of each webbing 22a, 22b, 22c, 22d is foldable to overlie an external side 25 of a respective one of end members 18a, 18b.

(10) As particularly shown in FIGS. 4 and 5, each inner triangular section 24a extends between the base member 12 and an upper section 28 of a respective one of the end members 18a, 18b. The inner triangular section 24a of each webbing 22a, 22b, 22c, 22d is preferably coupled to an external side 25 of a respective end member 18a, 18b. Each inner triangular end section 24a is coupled to a respective end member 18a, 18b by a fastener 30. Preferably, the fastener 30 is a glue. Alternatively, any other suitable fastener 30 can be used.

(11) The outer triangular section 24b of each webbing 22a, 22b, 22c, 22d extends between the base member 12 and an upper section 32 of a respective side member 14a, 14b.

(12) A common side 34 of the inner and outer triangular sections 24a. 24b of each webbing 22a, 22b, 22c, 22d extends at an angle of 45 upwardly from a plane of the base member 12. Alternatively, the common side 34 extends at a suitable alternative angle which is around 45.

(13) The container 10 has been designed with a view to holding 10 Kilograms of broccoli, for example. In this embodiment, the container 10 includes the following dimensions:

(14) D.sub.1=210 mm

(15) D.sub.2=101 mm

(16) L=542 mm

(17) W=348 mm

(18) A=45

(19) The container 10, blank 100 and 200 could include any other suitable combination of the above mentioned dimensions.

(20) The upper end sections of the webbings 22a, 22b, 22c, 22d are raised a distance D.sub.2 of from the plane of the base member 12. This distance reduces loss of fluids, such as ice water. from the container 12. Further, the webbings 22a, 22b, 22c, 22d are folded around respective end members 18a, 18b which has a sealing effect which inhibits egress of fluids such as ice water from the container.

(21) As particularly shown in FIG. 6, the container 10 preferably includes the following layers of material:

(22) a. a polyethylene terephthalate (PET) film layer 40 of 17 GSM;

(23) b. a low density poly ethylene (LDPE) layer 42;

(24) c. an inner kraft layer 44 of 170 grams per square meter (GSM);

(25) d. a medium 190 GSM semi-chemical paper layer 46;

(26) e. a laminate layer 48 including:

(27) i. a kraft inside, 150 GSM Kraft Liner ii. a LDPE film 15 GSM; iii. a Kraft outside; MG50UnBL

(28) The PET film layer 42 provides at food grade water proof surface for ice and direct food contact.

(29) The container 10 shown in FIG. 3 is collapsible into a flat pack 200 for transportation by folding the end members 18a, 18b down over the base member 12, and folding the side members 14a, 14b down over the end members 18a, 18b in the manner shown in FIG. 4. The outer triangular sections 24b of each webbing 22a, 22b, 22c, 22d overlie an external side 25 of a respective end member 18a, 18b when collapsed into the flat pack 200. The flat pack 200 is expanded into the container 10 in the manner shown in FIGS. 4 and 5 by reversing this process.

(30) Advantageously, the outer triangular sections 24b of the webbings 22a, 22b, 22c, 22d are coupled to respective inner triangular sections 24a. The outer triangular sections 24b of the webbings 22a, 22b, 22c, 22d are preferably coupled to respective inner triangular sections 24a with a fastener such as an adhesive.

(31) The container 10, blank 100 and 200 includes any other suitable combination of materials, as described in U.S. Pat. No. 5,609,293.

(32) Outer or lid component being a full carton depth provides thermal insulation and a majority combined unit stacking strength. The layers of board also protect the inner vessel from impact and side intrusion from sharp objects.

(33) Corrugated packaging is a more environmentally friendly alternative to polystyrene packaging. To this end, the corrugated packaging is a recyclable product.

(34) The problems associated with warehousing the bulky poly styrene products are obviated by providing the erectable flat pack 200 to farmers. This also reduces cost of freight of erectable packaging to the farmers.

(35) Many modifications will be apparent to those skilled in the art without departing from the scope of the present invention

(36) Throughout this specification, unless the context requires otherwise, the word comprise, and variations such as comprises and comprising, will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
