Description

WASTE BIN

BACKGROUND TO THE PRESENT INVENTION

Conventional domestic and light commercial waste management systems typically rely upon a system of primary and secondary containment utilising products manufactured from [DPE (linear low density polyethylene) as primary containers, commonly referred to as bin liners, and from stainless steel and HDPE (high density polyethylene) as secondary containers, commonly referred to as bins and wheelie bins. Systems using primary and secondary waste containers promote the accumulation of bacteria within internal environments, through the permanent retention of secondary waste containers within internal spaces, and after disposal, particularly when refuse is stockpiled. Further, manufacturing of the primary and secondary containers depletes the finite levels of mined and extracted natural resources whilst disposal increases the enduring footprint of global contamination, whether disposal occurs at landfill sites or through alternative means of disposal including combined heat and power.

SUMMARY OF THE PRESENT INVENTION

From a first aspect, the present invention provides a waste container comprising an opening, a permanent closure member, and an adhesive attached to the closure member for irreversibly sealing the closure member to another part of the container so as to permanently close the opening in the container.

For the avoidance of doubt, the irreversible sealing of the closure member to another part of the container so as to close the opening of the container means that the closure member cannot be unsealed without destroying or damaging at least a portion of the container. Permanently closing the opening in the container means that the opening cannot be reopened without destroying or damaging at least a portion of the container.

Irreversibly sealing the container allows the user to dispose of the waste container without fear of leakage from the container, or of the container reopening, for instance if it is knocked onto its side. It also allows the user to leave the container undisposed for a time without waste or odours escaping before they dispose of the container.

When the opening of the container is sealed closed by the closure member, the opening may be entirely covered such that the interior of the container cannot be accessed therethrough.

When the opening of the container is sealed closed by the closure member, the container may be closed such that there are no openings through which the interior of the container can be accessed.

When the opening is sealed closed by the closure member, the container may be sealed closed in a watertight and/or gas-tight manner. The container may be considered to be sealed in a watertight and/or gas-tight manner when the pressure inside the container is atmospheric or ambient pressure.

The irreversible sealing means may comprise multiple strips and/or types of adhesives.

The adhesive(s) used as the irreversible sealing means may be provided directly to a surface of the closure member, with no additional pads necessary. Further, it lies flat against the surface, so does not interfere with the function of the container prior to its activation, when it is required to irreversibly close the container.

The adhesive(s) may be a double sided adhesive tape joined on one side to the closure member, the other side for engaging said another part of the container.

The closure member may further comprise a peel strip(s) covering the adhesive(s), wherein the peel strip(s) is releasably adhered to the adhesive so as to prevent the adhesive from adhering to other components prior to the peel strip being removed. In use, the peel strip may be removed to enable the adhesive to engage and adhere to said another part of the container so as to irreversibly seal the closure member to said another part of the container to permanently close the opening in the container.

The waste container may comprise a bottom panel for forming a base of the container, at least one top panel for forming the closure member, and at least one side panel for forming a side wall of the container; wherein the bottom panel is irreversibly sealed to at least one of the at least one side panels.

The bottom panel and at least one side panels may be irreversibly sealed together using waterproof joints such as lapped joints. By using waterproof joints. water and other fluids are unable to escape from the container through the joints between the panels, i.e. fluids cannot escape the container except through the opening.

The waste container may be formed from paperboard or cardboard. Paperboard and cardboard are strong, lightweight, easy to process and disposable. The container can thus be easily formed and disposed of. After use, the entire container can be disposed of with minimal environmental impact. Thus, the container can be manufactured, marketed, sold and used as a disposable item: once the container has been filled with waste, it can be irreversibly sealed, and the container along with its contents disposed of. The strength of the paperboard or cardboard enables the container to be self-supporting, and provides rigidity to the structure.

The paperboard or cardboard may be water resistant or waterproof.

The paperboard or cardboard may have a hydrophobic coating or layer to render it waterproof or water resistant. For example, the paperboard or cardboard may be waxed paperboard or cardboard.

The water resistant paperboard or cardboard enables the waste container to be used for wet or moist waste, for example kitchen waste. It prevents moisture soaking into the paperboard or cardboard, which could compromise the integrity of the paperboard or cardboard and, therefore, the container, and also allow liquid to escape from the container, for example to permeate through the bottom or sides thereof, which would be undesirable.

Further, if large amounts of liquid or moisture were to permeate into the paperboard or cardboard, the paperboard or cardboard would lose its rigidity and structural integrity, potentially causing the container to collapse or the panels or walls thereof to break or have holes formed therein. Providing water resistant paperboard or cardboard eliminates the need for a secondary containment layer, such as a bin liner, e.g. when used for wet or moist waste.

Although the container has been described as being formed from paperboard or cardboard, other material are contemplated. For example, although less desirable, the container may be formed from plastics.

The waste container may be formed from a single blank of material.

The waste container may further comprise a reversible closing mechanism for reversibly closing the opening prior to irreversibly sealing the container with the permanent closure member. This allows a user to reversibly close the container when it is only partially full, for example to prevent the waste therein from being visible, or to block odours emitted therefrom, then reopen the container when desired to put more waste therein. This operation can be completed as many times as necessary, before the waste container is full. The waste container can then by irreversibly sealed using the closure member before being disposed of.

The reversible closing mechanism may close the opening of the container by entirely covering the opening such that it is not possible to access the interior therethough.

This may close the opening of the container such that there are no openings through which the interior of the container can be accessed. The mechanism may reversibly close the opening of the container so as to allow the opening to be transferred from the closed state to an open (i.e. not closed) state as many times as desired without destroying or damaging any portion of the container.

The reversible closing mechanism may comprise a reversible closure member and a reversible sealing mechanism for reversibly sealing the reversible closure member to another part of the container so as to reversibly close the opening in the container.

The reversible sealing means may be an adhesive, hook and loop material, or any other kind of mechanical fastener, such as a cooperating tab and aperture that reversibly interlock. The reversible closure member may comprise a first mechanical fastener and said another part of the container may comprise a second mechanical fastener element for cooperating with the first mechanical element to perform the reversible sealing.

The permanent closure member and the reversible closure member may be the same member. Said same member may have the adhesive thereon in addition to the reversible sealing means.

The waste container may comprise a first closure panel and a second closure panel for reversibly closing the opening of the container.

One or more slots or apertures may located on the first closure panel, and one or more tabs may be located on the second closure panel for insertion through the slots or apertures to reversibly close the opening of the container.

The tabs can be inserted through the slots or apertures to close the container. The tabs can then be extracted from the slots or apertures to reopen the container. This operation is reversible and, thus, may be repeated as many times as necessary. This provides a simple resealing device.

One of the first and second closure panels may be said permanent closure member comprising said adhesive, and the other of said first or second closure panels may be said another part of the container.

The first and/or second closure panel may be a top panel for being closed over said opening.

When the container is reversibly sealed, the inside surface of one of the first and second closure panels may contact the inside surface of the other of the first and second closure panels.

When the container is irreversibly sealed, the first and second closure panels may overlap such that the inside surface of one of the first and second closure panels contacts the outside surface of the first and second closure panels.

The first and/or second closure panel may comprise a handle aperture for use as a lifting handle.

The container may have a height selected from the group consisting of: »=lOcm; »=2Ocm; »=3Ocm; »=4Ocm; »=SOcm; »=6Ocm; »=7Ocm »=8Ocm; »=9Ocm; and »=lOOcm.

The container may have a width selected from the group consisting of «=5Ocm; «=45cm; «=4Ocm; «=35cm; «=3Ocm; «=25cm; and «=2Ocm.

The waste container may be configured to fold between a folded collapsed state and an unfolded expanded in use state. The waste container can be provided to a user in the collapsed state. The user can then unfold and erect the container into the in use state.

The container in the collapsed state has a smaller volume than in the in use state, meaning it can be transported and stored more easily.

The area of the at least one top panel may be greater than the area of the top opening of the container.

The adhesive may form a watertight and airtight seal around the opening such that water and other fluids are unable to escape from the container after the opening has been closed by the permanent closure means.

The container may have at least three side walls and a closure panel extending from the upper edge of each side wall for folding over the opening so as to close the container, and wherein the side edges of each closure panel are connected or sealed to the side edges of the adjacent closure panels.

The container may have at least three closure panels configured to fold over the opening so as to close the container, wherein a first of the closure panels comprises said permanent closure member, and where at least one of the closure panels laterally adjacent to the first closure panel is configured to fold over on itself when said first closure panel is folded over the opening. The container may have at least four side walls. The laterally adjacent closure panels may be joined to different side walls of the container. The at least one laterally adjacent closure panel may comprise a closure member, such as an adhesive, configured to adhere the closure panel to itself whilst folded over on itself The connected or sealed side edges may be connected or sealed in such a manner that there is a gas and/or water tight seal between them. This prevents gas and/or water escaping from the container (at least between the closure panels) when the closure panels are closed over the opening.

DETAILED DESCRIPION OF EMBODIMENTS

Figure 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 Sa 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.

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.

The panels are separated by score lines ito 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.

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

Figure 2.1 shows a side view with cut outs of an embodiment of a waste container formed from the blank of figure 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, ii and 12 form waterproof seals. As such, the container body of the container is watertight.

Figure 2.2 shows a side view of the waste container of Figure 2.1 during its assembly from the blank of Figure 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.

Figures 3.1 and 3.2, 4.1 and 4.2 show a waste container being assembled from the blank of Figure 1. Firstly, the waste container is formed by adhering the jointing surfaces together, as in Figures 2.1 and 2.2. Figure 3.1 shows a partially constructed waste container, wherein side panels A and D have been adhered together. Figure 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 Figure 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 Figure 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.

Figure 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).

Figures 5.2 and 5.3 show opposing side views of the top portion of a waste container of Figure 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.

Figures 6.1 and 6.2 show side views of the top portion of a waste container formed from the blank of Figure 1. Figures 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 Sc and Sd along their score lines, and folds the first closure panel 5a underneath the second closure panel Sb (Figure 6.1). Panels Sc and Sd collapse onto themselves along the score lines. The second closure panel Sb folds between first closure panel 5a and the collapsed panels Sc and 5d. The user then exerts downward pressure on the top of the container. Adhesives 6b irreversibly seal panels 5c and Sd to themselves. The inside surface of the second closure panel Sb 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.
