BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates generally to an apparatus used for cleaning containers. More particularly, the present invention relates to an improved utensil for cleaning containers such as baby bottles and cups, including the internal surfaces thereof.
2. Brief Description of the Prior Art
The importance of proper hygiene when handling and cleaning infant feeding containers such as baby bottles cannot be overstated. Ideally, bottles should be thoroughly scrubbed with detergent, and thereafter sterilized between uses such as by immersion in boiling water or other similar process.
The use of bottle scrubbing brushes during the cleaning process is well known in the prior art. Such bottle brushes take many forms, but generally consist of a utensil having a shaft with a number of bristles secured at or near the distal end of said shaft. In most cases, such bristles radiate outwardly from the shaft to provide a cleaning brush that can be inserted into the interior of a bottle to be cleaned.
To scrub most effectively, the cleaning surfaces of the brush should be pressed firmly against the inside wall of a baby bottle. The larger the brush, the more such scrubbing pressure tends to be created when the brush is constrained within the bottle. Unfortunately, articles such as baby bottles have relatively narrow mouths or openings, and brushes must be passed through such restricted openings in order to fit within and access the inner surfaces of such bottles.
Accordingly, the need arose for a bottle brush (and, more particularly, the bristles of such brush) capable of compressing to pass easily through a narrowed opening of a bottle, while still generating sufficient expansive force for effectively scrubbing the interior surfaces of such bottle. Flexible brushes are desirable for combining the benefits of compressibility with the expansive force of a larger brush. Although flexible brushes are generally efficient utensils for scrubbing the interior of baby bottles, these articles present several difficulties in practice.
One very significant disadvantage resulting from the compressibility of flexible brushes is the resulting spray caused by the expansion of bristles as such brushes are withdrawn through a restricted bottle opening. The rapid expansion of a brush (and, more particularly, the flexing of the bristles) as a brush is removed from a bottle opening creates a spray capable of inadvertently contaminating sterile containers and/or clean surfaces across significant distances. Such spray can also spread to a person cleaning a bottle and/or the surrounding environment. For this reason, a need still exists in the art for a brush which will overcome known problems associated with cleaning bottles and other containers with conventional brushes.

SUMMARY OF THE PRESENT INVENTION

It is an object of the invention to provide an improved bottle brush apparatus, for cleaning articles such as baby bottles. It is a particular object of the present invention to provide an improved bottle brush apparatus that can generate sufficient expansive bristle force for scrubbing against the wall of a bottle when positioned within such bottle, yet can pass easily through a restricted opening of such bottle for insertion and removal. It is a still more particular object of the present invention to provide an improved bottle brush apparatus having a splash shield to prevent inadvertent contamination of people or objects in the vicinity of such apparatus.
The present invention provides a bottle brush apparatus having a splash shield removeably secured to a handle, wherein such splash shield surrounds a scrubbing portion at the end of the handle. The scrubbing portion includes a plurality of radially extending bristles disposed along the length of a bristle stem. The splash shield operates to contain any splashing caused during insertion of the scrubbing portion into, and withdrawal from, a container such as a baby bottle.
