Containers for holding materials
The invention provides for a container that may include a liquid-holding vessel and a skeleton shell supporting the liquid holding vessel. The liquid-holding vessel may comprise a flexible polymer or plastic material for preventing contact between a liquid stored in or dispensed from the container and the skeleton. The liquid-holding vessel and the closure may be formed from a minimal amount of polymer or plastic. The invention also provides for a connection of a liquid-holding vessel with a fitment to the skeleton shell using ultrasonic means. Further, a skeleton shell with mating features allowing the skeleton shell to be formed with smooth edges is provided.
1. A container comprising a hollow shell, the hollow shell defining a container body of the container, the container including a dispensing aperture, and a bag or liner provided within the hollow shell, and being secured to the hollow shell at least about the dispensing aperture, the hollow shell formed from a recycled and/or biodegradable pulp material, the shell being moulded as an open shell which is then folded to form the hollow shell or being moulded in a number of parts which are joined together to form the hollow shell, wherein a series of flap features are formed in an alternating configuration such that at least one of the flap features formed on one side of the shell is positioned from an inner surface of the hollow shell and in between flap features formed on another side of the shell to prevent separation, wherein the flap features on the two sides of the shell overlap along a length of the hollow shell creating a substantially smooth external shell surface suitable for handling, labeling or the attachment of labels without protrusion of the flap features.
2. A container according to claim 1 , in which the pulp material is selected from the group including wood pulp and paper pulp.
3. A container according to claim 1 , in which the bag or liner is attached by an adhesive, by tape, or by shrink wrapping.
4. A container according to claim 1 , in which the bag or liner is provided loosely within the hollow shell.
5. A container according to claim 4 , in which the bag or liner is connected to the inside of the hollow shell at discrete positions.
6. A container according to claim 1 , in which the bag or liner is formed of a biodegradable material.
7. A container according to claim 1 , in which the hollow shell includes at least an extension portion, flap or similar feature arranged to extend over and attach to another portion of the hollow shell to assemble the hollow shell.
8. A container according to claim 1 , in which the hollow shell includes one or more flanges that are joined together to join one or more parts of the hollow shell.
9. A container according to claim 1 , in which the connection between the bag or liner and the outer surface of the hollow shell is rupturable so that the bag or liner can be separated from an outer surface of the hollow shell and removed from the interior of the hollow shell.
10. A container according to claim 1 , where the flap features can be formed as hooks shapes, arrowheads shapes, T shapes, L shapes, J shapes and Y shapes.
11. A container according to claim 1 , the at least one of the flap features formed on one side of the shell is deformable to be inserted into a slotting feature of another side of the shell.
