Abstract: A filter device removably retainable within a bottle for filtering fluid passing out of the bottle. The filter device is arranged to be insertable into any bottle. The filter device includes an insert component and a filter cartridge component. The insert includes an inlet and an outlet. It enables removable insertion into the bottle mouth with an interface sufficient to ensure that fluid cannot easily leak out around the sides of the device when in use. The filter cartridge is arranged to retain one or more filter media therein. It includes a fluid entry configured to direct fluid from within the bottle to come into contact with the filter media prior to its passage to the outlet. The filter device may be formed as a unitary structure or as a multi-component structure.

Abstract: The invention relates a Bottle Insert comprising an insert that (optionally, removably) resides inside the uppermost portion of a wide mouth bottle. The insert is circular in shape and has sidewalls and an integral base portion. The base portion rises in one or more locations to a flat plane located near the top of the circular shape and extending approximately one third of the diameter distance into the circular shape. The raised flat portions comprise one or more cut out areas for the purpose of drinking liquid contained within the bottle. Each such cut out area follows the inner diameter of the circular shape at one edge and following the contour of the rest of the raised portion of the flat area. The lower base portion has one or more drain holes. The insert is constructed of injection molded, food grade plastic.
