FABRIC CARE PRODUCTS
FIELD OF THE INVENTTON
The present invention relates to fabric care products having a self-venting press tap.
BACKGROUND OF THE INVENTION
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.
There is a need to provide a laundry care product that is free of venting chinineys and allows manufacturing to completely fill container with fabric care product, and yet still provide the convenience of a dispensing tap for larger sizes of fabric care products.
See e.g., WO 2007/108025; US 6,631,744; US 6,029,858; US D429,643.

DETAILED DESCRIPTION OF THE INVENTION
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.
One aspect of the invention provides a laundry care product that is free of a venting chimney. The term "venting chimney" means an opening in the container, typically releasably sealed with a venting closure, for the purposes of filling the container with a laundry composition and/or venting the container (i.e., introducing air into the container to release the vacuum that is otherwise created from dispensing the composition contained in the container).
The venting chimney typically has an inner diameter from about 2 cm to about 3 cm. The venting chimney may be integral to the container (e.g., formed as part of blow molding process).
The venting closure is typically functionally attached to the venting chimney.
Non-limiting examples of venting closures includes a screw cap, snap cap, pull cap, venting cap, or any sealing mechanism known in the art for removably sealing a venting chimney.
Another aspect of the invention provides a method of manufacturing a laundry care product comprising the steps: (i) providing a plastic container containing a contained volume and single opening accessing the contained volume; (ii) filling the plastic container with a liquid laundry care composition through the single opening until the composition occupies at least 92%
of the contained volume; (iii) functionally attaching a self venting tap to the single opening of the container.

Such a self-venting tap is described in WO 2007/108025 and the Canadian equivalent CA 2,646,575.
One aspect of the invention provides a laundry care product that is free of a venting chimney. The term "venting chimney" means an opening in the container, typically releasably sealed with a venting closure, for the purposes of filling the container with a laundry composition and/or venting the container (i.e., introducing air into the container to release the vacuum that is otherwise created from dispensing the composition contained in the container).
The venting chimney typically has an inner diameter from about 2 cm to about 3 cm. The venting chimney may be integral to the container (e.g., formed as part of blow molding process).
The venting closure is typically functionally attached to the venting chimney.
Non-limiting examples of venting closures includes a screw cap, snap cap, pull cap, venting cap, or any sealing mechanism known in the art for removably sealing a venting chimney.
There are typically instructions, on containers that have a venting chimney, that state, "Twist cap for quicker flow," or "Twist cap to vent" with an arrow directed the consumer which direction (e.g., counterclockwise). A non-limiting example of a venting chimney and venting closure includes one described in US 6,631,744, so called "vent 56" and "venting cap 58,"
respectively. In one embodiment, the product of the present invention is free of any venting closure (i.e., independent from the self venting tap). In another embodiment, the product is free of any other venting mechanism other than what is integral to the self-venting tap, such as, but not limited to, venting membranes or the like.
Another aspect of the invention is directed to maximizing the fill volume of the container with fabric care composition. The container of the fabric care product of the present invention contains fabric care composition. The volume (irrespective of what occupies the volume) that is contained by the container may be described by a contained volume. In turn, the contained volume may have a fluid volume of laundry care composition occupying the fill volume of the container (i.e., contained by the container) with the remainder as a void volume. Void volume is the volume (of the overall fill volume of the container) not occupied by the laundry care composition, e.g., air. In one embodiment, the fluid volume is about 92%, or more than about 92%, by volume of the contained volume; alternatively 93%, 94%, 95%, 96%, 97%, 98%, 99%, or more than 99% by volume of the contained volume. The void volume is about 5%, or less than about 3%, by volume of the contained volume; alternatively 7%, 6%, 5%, 4%, 3%, 2%, 1%, or less than about 1% of volume of the contained volume.
Without wishing to be bound by theory, the absence of a venting chimney allows the contained volume to be maximized with laundry care composition. In one embodiment, the volume of the fabric care composition contained in the container is from about 2 liters to about 8 liters, alternatively 3 liters to about 7 liters, alternatively from about 4 liters to about 6 liters, alternatively combinations thereof.
The containers of this invention can be made of plastic, preferably of a rigid plastic.
Non-limiting examples of plastic includes thermoform plastics and thermoset plastics, such as high density polyethylene, polymethylmethacrylate, polycarbonate, diethyleneglycol bisarylcarbonate, polyethylene terephthalate, polyethylene naphthalate, polyvinyl chloride, polyurethane, epoxy resin, polyamide-based resins, low density polyethylene, styrene butadiene copolymers, acrylonitrile, acrylonitrile-butadiene copolymer, cellulose acetate butyrate and mixtures thereof. The container may also comprise a handle, suitable for grasping by a consumer (see e.g., US 6,631,744 so called "handle 46"). The container may also comprise a measuring cup (see e.g., US 6,631,744 so called "closure/measuring cup 44").
The container may be made by blow-molding the plastic.
The fabric care composition of the present invention are preferably liquid, preferably water comprising compositions. In one embodiment, the fabric care composition comprises a liquid laundry detergent; preferably comprising detersive levels of anionic surfactant, ionic surfactant, or combinations thereof; preferably comprising a basic pH.
