Abstract

A diaper pail includes a housing and a lid assembly with a first lid that provides access to an interior of a flexible bag assembly, a second lid that provides access to the bag assembly's top structure, and a third lid cartridge that accommodates the bag assembly. An outer edge of the third lid cartridge forms a gap with the housing to allow a top portion of a bag through the gap. The lid assembly also includes a pair of overlapping planar sheets which pinch the bag to prevent odors from within the bag from passing to the outside.

Claims (36)

1 . A diaper pail, comprising:

a housing; and

a lid assembly attached to the housing, the lid assembly having:

a first lid that allows access to an interior of a flexible bag assembly housed within the housing;

a second lid that allows access to a top structure of the flexible bag assembly housed within the housing;

a third lid cartridge that accommodates the flexible bag assembly, wherein an outer edge of the third lid cartridge creates a gap with an inner surface of the housing to allow a top portion of a bag created by the flexible bag assembly therethrough; and

a pair of planar sheets that overlap with each other and pinch a portion of the bag formed by the flexible bag assembly, wherein the pair of planar sheets are composed of elastic material.

2 . The diaper pail of claim 1 , wherein the flexible bag assembly comprises a single use flexible bag having an attachment frame.

3 . The diaper pail of claim 2 , wherein the attachment frame is secured to the third lid cartridge.

4 . The diaper pail of claim 1 , wherein the flexible bag assembly comprises a cassette adapted to dispense a flexible tubing.

5 . The diaper pail of claim 4 , wherein the cassette is secured to the third lid cartridge.

6 . The diaper pail of claim 1 , wherein the flexible bag assembly comprises a single bag.

7 . The diaper pail of claim 6 , wherein the single bag is secured to the third lid cartridge by pulling an upper open end of the single bag over into the gap.

8 . The diaper pail of claim 1 , wherein the second lid and the third lid cartridge both have a central opening.

9 . The diaper pail of claim 1 , wherein the first lid rotates about a first hinge attached to an upper end of the housing.

10 . The diaper pail of claim 1 , wherein the second lid and third lid cartridge rotate about a second hinge attached to an interior of the housing.

11 . The diaper pail of claim 1 , wherein the pair of planar sheets are positioned in the third lid cartridge.

12 . The diaper pail of claim 1 , further comprising a linear gap which is formed by the overlap of one of the planar sheets over the other planar sheet.

13 . The diaper pail of claim 12 , further wherein the linear gap is a chord which extends from one point on a circular frame to another point on the circular frame, the chord not being a diameter of the circular frame.

14 . The diaper pail of claim 1 , wherein one of the planar sheets is positioned lower than the other planar sheet.

15 . The diaper pail of claim 14 , wherein the lower planar sheet has a U-shaped end that curves to an underside of a lower surface of the planar sheet.

16 . The diaper pail of claim 15 , wherein the U-shaped end of the lower planar sheet is positioned underneath an overlap area between the first planar sheet and the second planar sheet.

17 . A diaper pail, comprising:

a housing; and

a lid assembly attached to the housing, the lid assembly having:

a first lid that allows access to an interior of a flexible bag assembly having a bag and housed within the housing;

a second lid that allows access to a top structure of the flexible bag assembly housed within the housing;

a third lid cartridge that is pivotally attached to the second lid and accommodates the flexible bag assembly, wherein an outer edge of the third lid cartridge creates a gap with an inner surface of the housing to allow a top portion of the bag therethrough; and

a pair of planar sheets composed of elastic material and that overlap with each other and pinch a portion of the bag formed by the flexible bag assembly.

18 . A diaper pail, comprising:

a housing having an upper end and a lower end; and

a lid assembly attached to the upper end of the housing, the lid assembly having:

a first lid pivotally attached to the upper end of the housing and allows access to an interior of a flexible bag assembly having a bag and housed within the housing;

a second lid that allows access to a top structure of the flexible bag assembly housed within the housing;

a third lid cartridge pivotally attached to the second lid and that accommodates the flexible bag assembly, wherein an outer edge of the third lid cartridge creates a gap with an inner surface of the housing to allow a top portion of the bag created by the flexible bag assembly therethrough; and

a pair of planar sheets composed of elastic material and positioned within the third lid cartridge that overlap with each other and pinch a portion of the bag formed by the flexible bag assembly.
