Benefits of technology

"The present invention provides a laundry care product that includes a plastic container containing a laundry care composition and a self venting tap functionally attached to the container. The container is free of a venting chimney, which allows the composition to be dispensed from the container without the need for a separate vent. The product also includes a void volume and a fluid volume of the liquid laundry care composition, with the void volume being about 8% or less by volume and the fluid volume being about 92% or more by volume. The method of manufacturing the product involves filling the container with the liquid composition through a single opening and attaching the self venting tap to the opening. The technical effects of this invention include improved storage and dispensing of laundry care compositions in a more convenient and efficient manner."

Problems solved by technology

Consumer may find it undesirable to releasably open a venting chimney and to have fabric care composition come out through the opened venting chimney.

Embodiment Construction

[0008]One aspect of the invention provides a laundry care product that comprises a self venting tap functionally attached to the container of the product. “Self venting tap” means a tap suitable for dispensing liquids, preferably of varying viscosities, wherein the tap itself capable of venting, i.e., allowing air to pass from the outside of the container to inside the container to release a vacuum that is produced from when the liquid laundry care composition is dispensed from the container. In a preferred embodiment, the self venting tap is a self venting press tap. A non-limiting example of a self venting press tap includes one from Vitop Moulding S.R.I, Italy. Such a self-venting tap is described in WO 2007 / 108025 and the Canadian equivalent CA 2,646,575. The U.S patent publication or patent grant equivalent thereof is hereby incorporated by reference when it becomes available.

Abstract

Laundry care products comprising a plastic container containing a laundry care composition, wherein the container comprises a self venting tap functionally attached to the container, provides for a product that is free of a venting chimney and / or the container's fill volume to be maximized.

Description

FIELD OF THE INVENTION[0001]The present invention relates to fabric care products having a self-venting press tap.BACKGROUND OF THE INVENTION[0002]Laundry care products having press taps are well known. These products are typically characterized by larger sizes, i.e., about four liters or greater. These products typically have plastic containers that may have venting chimneys to allow air to enter into the container to release a vacuum that may be created when the composition is dispensed from the container via the dispensing tap. Venting chimneys may require a significant amount of plastic when containers are blow-molded (e.g., 6-11% by weight of the blow molded plastic container). Venting chimneys may also require manufactures not to fill container completely full. Consumer may find it undesirable to releasably open a venting chimney and to have fabric care composition come out through the opened venting chimney.[0003]There is a need to provide a laundry care product that is free ...
