DETAILED DESCRIPTION OF EMBODIMENTS

[0069] FIG. 1 shows an embodiment of a blank E for forming a waste container. The blank is a single sheet formed from paperboard. The blank E comprises four elongated side panels A, B, C and D. The panels are connected sequentially along their side edges. The blank further comprises two bottom panels F connected to the ends of side panels A and C. The first bottom panel F is connected to the same end of panel A as the end of panel C to which the second bottom panel F is connected. The blank further comprises a first closure panel 5a and a second closure panel 5b connected to side panels A and C at the opposite end to bottom panels F. The first and second closure panels 5a and 5b each have a handle aperture 3 for use as holding handles. The first closure panel 5a includes two tabs 4a. The second closure panel 5b includes two locator slots 4b for insertion of the two tabs 4a in use, as will be described in more detail below.

[0070] Double sided adhesive strips 6, covered by peels strips, are provided on the second closure panel 5b and on closure panels 5c, 5d to attached side panels B and D for irreversible sealing, as will be described in more detail below.

[0071] The panels are separated by score lines 1 to aid in the folding of the blank. Further score lines 1 are included in some of the panels to aid in the collapsing of the waste container once formed, as will be described below.

[0072] The edges of the blank to be joined to other portions of the blank when the waste container is formed therefrom include portions 2 for forming lapped joints. Cut lines 7 ensure that the blank can be folded where necessary.

[0073] FIG. 2.1 shows a side view with cut outs of an embodiment of a waste container formed from the blank of FIG. 1. The blank has been folded along scored lines 1, and adhesive applied to portions 2 to form lapped joints at the jointing surfaces 8, 9, 10, 11 and 12. The side panels A, B, C and D form side walls, and bottom panels F form a base. The blank thus forms a rectangular prism. The shape of the container, along with the material thereof form a self-supporting structure. The lapped joints at the jointing surfaces 8, 9, 10, 11 and 12 form waterproof seals. As such, the container body of the container is watertight.

[0074] FIG. 2.2 shows a side view of the waste container of FIG. 2.1 during its assembly from the blank of FIG. 1. Adhesive has been applied to the jointing surfaces 8, 9, 10, 11 and 12 prior to their attachment to other portions of the container.

[0075] FIGS. 3.1 and 3.2, 4.1 and 4.2 show a waste container being assembled from the blank of FIG. 1. Firstly, the waste container is formed by adhering the jointing surfaces together, as in FIGS. 2.1 and 2.2. FIG. 3.1 shows a partially constructed waste container, wherein side panels A and D have been adhered together. FIG. 3.2 shows a fully constructed waste container, wherein the bottom panels F have also been adhered both to each other and to side panels B and D. Pressure is then exerted on the vertical scoring lines to collapse the waste container, and the first and second closure panels are folded backwards. This forms a collapsed product ready for storage and transportation, as can be seen in FIG. 4.1. The container can then be prepared for use by an end user by expanding the container out into its expanded configuration, as can be seen in FIG. 4.2. The container has an opening at the end opposite the base formed by bottom panels F. Aside from this opening, the container is waterproof and watertight. The container can then be resealably closed or permanently closed, as described in more detail below.

[0076] FIG. 5.1 shows an embodiment of the waste container in its expanded configuration, the opening being resealably closed. The inside surface of the first closure panel contacts the inside surface of the second closure panel 5b, and the handle apertures 3 align so as to form a single handle. The tabs 4a are then aligned with the slots (not shown) for insertion therethrough (not shown).

[0077] FIGS. 5.2 and 5.3 show opposing side views of the top portion of a waste container of FIG. 5.1, wherein the tabs 4a are inserted into the slots 4b. In the illustrated embodiment, the tabs 4a are serrated to aid them to remain securely in the slots 4b. The tabs 4a can be extracted from the slots 4b to reopen the waste container.

[0078] FIGS. 6.1 and 6.2 show side views of the top portion of a waste container formed from the blank of FIG. 1. FIGS. 6.1 and 6.2 demonstrate the permanent closure of the opening of the container using the adhesive strips 6a, 6b. The user removes peel strips from the adhesive strips 6a, 6b in order to expose the adhesives. The user then folds panels 5c and 5d along their score lines, and folds the first closure panel 5a underneath the second closure panel 5b (FIG. 6.1). Panels 5c and 5d collapse onto themselves along the score lines. The second closure panel 5b folds between first closure panel 5a and the collapsed panels 5c and 5d. The user then exerts downward pressure on the top of the container. Adhesives 6b irreversibly seal panels 5c and 5d to themselves. The inside surface of the second closure panel 5b contacts the outside surface of the first closure panel 5a, and the adhesive 6a thereon, and irreversibly seals thereto. Thus, the container is irreversibly sealed, and ready for disposal. The seals formed by the adhesives render the container water and gas tight.
