DESCRIPTION OF EMBODIMENTS

[0047] A perspective view from above and one corner of an embodiment of portable container 10 for transporting cakes is shown in FIG. 1. The portable container 10 comprises a container base 12, a first container section 14, a second container section 16 and a cover 18. The portable container 10 comprises six retaining members 20. As described in more detail below, four of the six retaining members 20 are used to prevent movement of a cake across the container base. The remaining two members 20 are stored in clips formed in the underside of the container base 12. The underside of the container base 12 defines sufficient number of clips to hold all the retaining members 20 when the retaining members are not in use. The container base 12 defines a substantially square support surface 22 for supporting a multi-tiered cake on its upper surface.

[0048] The container base is integrally formed from polypropylene which is coloured whereby the container base is opaque. The container base is described in more detail below with reference to FIGS. 2A and 2B. Each of the first and second container sections 14, 16 is open at a top and at a bottom and defines a space of substantially square cross-section which is enclosed by four sides of the container section. Each container section 14, 16 is integrally formed from polypropylene. As shown in more detail in FIGS. 3A and 3B, each container section 14, 16 comprises a living hinge 26 at the lower edge of each of the four sides. Each living hinge defines two elongate apertures spaced along the edge. Each container section 14, 16 further comprises two integrally formed elongate protrusions 28 at the upper edge of the outer surface of each of the four sides. The two elongate protrusions 28 are spaced apart along the upper edge at locations corresponding respectively to the elongate apertures of the living hinge 26. Furthermore, each elongate protrusion 28 and a corresponding aperture are sized and shaped such that the protrusion is a snap fit in the aperture in accordance with known practice for hinged connectors of this form. The cover 18 is closed at the top, open at the bottom and defines its recess of square cross-section by way of the closed top and four sides of the cover. The cover 18 comprises a handle 30 which is in the centre of the closed top of the cover and extends from the exterior upper surface of the cover. As is shown in more detail in FIG. 4, the cover 18 also comprises a living hinge 32 at the free edge of each of the four sides of the cover. Each living hinge 32 of the cover is of the same form and function as the living hinges 26 of the container sections 14, 16. The cover 18 is integrally formed from polypropylene. Each retaining member 20 is integrally formed from PC/ABS.

[0049] The portable container 10 is brought into use by locating a multi-tiered cake on the support surface 22 of the container base 12. According to a first example approach, the multi-tiered cake is formed in-situ on the container base 12. According to a second example approach, the multi-tiered cake is formed apart from the container base 12 and when complete is moved sideways onto the support surface 22 of the container base 12. The multi-tiered cake is then held in position on the support surface 22 against movement across the support surface by way of four of the retaining members 20. As described further below, each of the retaining members 20 is inserted in a respective slot 24 formed in the support surface 22 such that the retaining members are spaced around the cake and abut against the side of the bottom of the cake. For example, where the cake is of square footprint, a retaining member 20 is located against each of the four sides at the bottom of the cake. The first container section 14 is then lowered over the container base 12 such that the cake is received in the space defined by the first container section. When the lower edge of the first container section 14 abuts against the periphery of the container base 12, each of the four living hinges 26 of the first container section 14 is rotated downwards until it engages with the corresponding protrusion 34 which extends from the side of the container base 12 near the upper edge of the container base.

[0050] The second container section 16 is then lowered over the first container section 14 such that a further part of the cake is received in the space defined by the second container section. When the lower edge of the second container section 16 abuts against the upper edge of the first container section 14, each of the four living hinges 26 of the second container section 16 is rotated downwards until it engages with the corresponding protrusion 28 on the side of the first container section 14 near the upper edge of the first container section. Finally, the cover 18 is placed over the second container section 16 such that the remaining part of the cake is received in the recess defined by the cover. When the lower edge of the cover 18 abuts against the upper edge of the second container section 16, each of the four living hinges 32 of the cover 18 is rotated downwards until it engages with the corresponding protrusion 28 on the side of the second container section 16 near the upper edge of the second container section. The container base 12, the first and second container sections 14, 16 and the cover 18 are thus all held securely together whereby the portable container 10 may be lifted by the handle for transport of the cake elsewhere. Alternatively, and for example where the cake to be transported is particularly heavy, the portable container 10 may be lifted by way of the container base 12 as described below with reference to FIG. 2B.

[0051] FIGS. 2A and 2B are views from above and from one side respectively of the container base 12 of the portable container 10 of FIG. 1. Further features of the container base 12 will now be described. Four sets of slots 42 are defined in the support surface 22. The slots 44 in each set of slots 42 are spaced apart from each other in a direction which extends away from the centre of the support surface 22 towards an edge of the support surface. Directions of spacing apart of slots 44 in adjacent sets of slots 42 are at 90 degrees to each other. A retaining member 20 is inserted into one of the slots 44 in each set of slots 42 whereby cakes of different sizes may be accommodated. As may be seen from FIG. 2B, a lifting recess 46 is defined in the side of the container base 12. The lifting recess 46 is of sufficient dimensions to admit the fingers of one hand. A lifting recess 46 is defined in each of the four sides of the container base 12. The portable container 10 may be lifted by inserting the fingers of each of two hands in a respective one of two lifting recesses 46 on opposite sides of the container base 12.

[0052] The retaining member 20 will now be described in more detail with reference to FIGS. 5A and 5B which provide side and end views respectively of the retaining member. The retaining member 20 comprises a spine of sheet form, albeit sheet form which follows a nonlinear path and which defines a lower and two outwardly and hence oppositely directed side surfaces of the retaining member. A centre part of the spine defines the lower surface of a middle part 52. The spine extends from each side of the middle part and away from the middle part to define first and second protrusions 54, 56 on each side of the middle part. The spine further extends at the distal end of each of the first and second protrusions 54, 56 away from the lower surface of the first and second protrusions to define first and second end parts 60, 62.

[0053] As may be seen from FIG. 5B, the spine and hence the first and second end parts 60, 62 are of finger width. The retaining member 20 comprises a barrier portion 58 which extends up from an upper surface of the spine and which extends along the middle part 52 and part way along each of the first and second protrusions 54, 56. Ends of the barrier portion 58 therefore do not extend as far as the first and second end parts 60, 62. Each of the first and second end parts 60, 62 is such that it resiliently flexes in relation to the intervening parts of the retaining member 20. Each of the first and second end parts 60, 62 defines a locking protrusion 64 on its outwardly directed surface. The width and length of the retaining member 20 and each slot 44 formed in the support surface 22 are such that the first and second protrusions 54, 56 are a clearance fit in the slot. The retaining member 20 is locked in position in a slot 44 by applying pressure to the first and second end parts 60, 62 between thumb and forefinger whereby the first and second protrusions 54, 56 are drawn towards each other and to an extent sufficient to enable the retaining member to be fully inserted into the slot such that the locking protrusions 64 are received beyond the support surface 22. The first and second end parts 60, 62 are then released whereby the first and second end parts 60, 62 spring apart such that the locking protrusions 64 extend underneath the support surface 22 to thereby lock the retaining member 20 in place. The retaining member 20 is removed by applying pressure to the first and second end parts 60, 62 between thumb and forefinger whereby the locking protrusions 64 are withdrawn allowing the retaining member to be withdrawn from the slot 44.
