Container systems with lids for unit dose detergent compositions

Abstract

A container system includes a tub including a front wall, a back wall opposite the front wall and side walls extending between the front wall and the back wall. A bottom extends between the front wall, back wall and side walls. A mouth structure includes a fastening feature configured for connecting to a lid. The mouth structure has an opening therethrough that provides access to a containing volume of the tub. A shoulder extends inwardly from the side walls to the mouth structure. A plurality of unitized doses of a detergent composition is located within the containing volume of the tub. A lid is connected to tub using the fastening feature. The lid has an open position for allowing user access to the containing volume and a closed position for preventing user access to the containing volume. A flexible membrane may be connected to the underside of the lid

Description

FIELD OF THE INVENTION[0001]One or more embodiments shown and described herein are generally directed to container systems and their lids for unit dose detergent compositions.BACKGROUND[0002]Detergent compositions, such as laundry detergent, may often be found in various forms such as powders, granules, liquids and gels, which are typically contained in a box-like container. Such containers may be perforated to allow formation of an openable lid to gain access to the detergent, or such containers may have a dispensing closure, such as a “push-pull” type of dispensing closure that can be selectably opened to allow a consumer to dispense the detergent from the container.[0003]Accordingly, improved detergent container systems are continually desirable.SUMMARY[0004]In certain embodiments detergent compositions in “unit dose” form may be provided. For example, detergent compositions may be provided in a single dose of compacted powdered detergent contained within a sealed, flexible membr...

[0004]In certain embodiments detergent compositions in “unit dose” form may be provided. For example, detergent compositions may be provided in a single dose of compacted powdered detergent contained within a sealed, flexible membrane to form such “unit dose”. During a wash cycle, the unit dose may be placed in water, wherein it disperses within the water of the wash cycle. Such unit dose detergent compositions may generally be sold in box-like plastic containers and a user may typically extract a unit dose for use by removing the lid of the container and then removing the desired unit dose through an opening of the container. Because unit dose composit
