Waste storage device
View Patent ↗A waste storage device is provided comprising a waste storage compartment for storing waste and a lid. The device further comprises a dispenser for dispensing an agent inside the waste storage device and an actuator arranged to activate the dispenser. A waste cartridge is also provided comprising a relatively rigid upper portion and a relatively flexible lower portion. The relatively flexible lower portion is arranged for storing waste items and the relatively rigid upper portion is arranged to be folded about an axis in a direction substantially towards the relatively flexible lower portion of the waste cartridge.
1. A waste cartridge comprising a relatively rigid upper portion and a relatively flexible lower portion, wherein said relatively flexible lower portion is arranged for storing waste items and wherein said relatively rigid upper portion is arranged to be folded about an axis in a direction substantially towards the lower portion of the waste cartridge wherein a first rib and a first recess are arranged on the rigid upper portion on one side of the axis and a second rib and a second recess are arranged on the rigid upper portion on the opposite side of the axis, wherein the relatively flexible lower portion is attached to the relatively rigid upper portion only between the first rib and the first recess and between the second rib and the second recess.
2. The waste cartridge as claimed in claim 1 wherein the relatively flexible lower portion comprises a bag.
3. The waste cartridge as claimed in claim 1 wherein the relatively rigid upper portion comprises a ring.
4. The waste cartridge as claimed in claim 1 wherein said relatively flexible lower portion is attached to an upper surface of said relatively rigid upper portion.
5. The waste cartridge as claimed in claim 4 wherein said relatively flexible lower portion is welded to the upper surface of said relatively rigid upper portion.
6. The waste cartridge as claimed in claim 1 the second recess located on the relatively rigid upper portion is arranged to cooperate with first rib, for sealing the upper portion in a folded configuration.
7. The waste cartridge as claimed in claim 6 wherein the first rib and cooperating second recess are arranged to trap material at the top of the relatively flexible lower portion there between, to form a sealed waste package when the relatively rigid upper portion is in a folded configuration.
8. A cartridge for storing waste comprising:
a lower relatively flexible material with an open top and a closed bottom;
a relatively rigid ring having
an upper ring surface,
a lower ring surface,
a first hinge substantially diametrically opposite a second hinge,
a hinge axis extending through the first hinge and the second hinge thereby defining a first ring portion and a second ring portion,
the lower ring surface of the first ring portion having a first rib and a first recess, and
the lower ring surface of the second ring portion having a second rib and a second recess;
wherein the lower relatively flexible material is secured to the relatively rigid ring only between the first rib and the first recess on the first ring portion and between the second rib and the second recess on the second ring portion; and,
wherein the first ring portion and the second ring portion are arranged to be folded about the hinge axis towards the lower relatively flexible material, such that the first rib cooperates with the second recess and the first recess cooperates with the second rib to secure the lower relatively flexible material between the first rib and the first recess on the first hinge portion and the second rib and the second recess on the second hinge portion.
9. The cartridge for storing waste as claimed in claim 8 wherein the lower flexible material is secured to the upper ring surface only between the first rib and the first recess on the first ring portion and only between the second rib and the second recess on the second ring portion.
