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...

AI Technical Summary

Benefits of technology

The patent describes a new way to make detergent in single-use form. These deterges are packed into small, flexible packages that can be easily dissolved in water. However, traditional containers for these packages have a lid that's difficult to remove because it's designed to keep water out. The patent introduces a new container design that makes it easier to open and use the detergent inside. This design is easy to handle and works well against moisture, which is important for keeping the detergent fresher and more effective.

Problems solved by technology

However, in order to inhibit the entrance of water into the container, the lids may typically have a resistance to their removal such that it takes both hands to remove the lid, i.e., one hand on the container and one hand removing the lid.
