Benefits of technology

A further object of this invention is to provide such a filter which is simple to manufacture and easy to use.

Problems solved by technology

The known practices of utilizing a filter for holding the beverage making substances, however, does not provide for any removal of contaminants before or after the water reaches the beverage making substances.
As a result, the contaminants can have adverse effects, such as causing a bitterness in the resultant beverage.

Embodiment Construction

The present invention will be described in particular detail in accordance with an illustrated practice where the filter is used for making coffee. Thus, the fluid is a liquid, specifically hot water. It is to be understood, however, that the invention may be practiced with other fluids ranging from those used for making beverages or drinks for human consumption to any other contaminant containing fluid such as gasoline, kerosene, spent lubricating or cooking oils and other fluids which are not ingested by humans or animals. In such practices specific filter members would be selected in accordance with the contaminant being removed.

FIGS. 1-3 illustrate a fluid filter 10 in accordance with this invention for making coffee. As shown therein fluid filter 10 is in the form of a pair of layers of material 12,14 which are laminated together in at least their central portion to form a .Iadd.fluid contacting region or area 16 having an upstream .Iaddend.fluid contacting surface .[.16.].. A ...

Abstract

A filter for fluids includes a pair of layers or multiple layers or pairs of material joined together to form a laminate having a fluid contacting surface. A plurality of spaced pockets is formed between the layers of material in the contacting surface. The layers of material are fluid permeable at the pockets whereby fluid may flow through the laminate at the pockets. The fluid contacting surface is fluid impermeable except for the pockets to require the fluid passing through the laminate to be confined to flowing through the pockets. Filter members are in the pockets for removing any contaminants from the fluid. Alternatively, additive materials such as powdered cream or sugar in the pockets dissolve in the fluid passing through the pockets to enhance the fluid.

Description

BACKGROUND OF THE INVENTIONThe present invention relates to variations and aspects of the inventions in my application Ser. No. 08 / 019,709, filed Feb. 19, 1993, now U.S. Pat. No. 5,304,305, the details of which are incorporated herein by reference thereto.Various beverages are made by flowing a fluid or liquid, such as hot water, through a beverage making substance, such as coffee grounds or tea. Other beverages or fluids are also mixed with water including food concentrates such as cocoa, baking or cooking mixes, juices, flavors, milk, soup, infant formula. It is known to hold the beverage making substance such as coffee grounds in a filter material when the water passes through the coffee grounds in making coffee. The known practices of utilizing a filter for holding the beverage making substances, however, does not provide for any removal of contaminants before or after the water reaches the beverage making substances. As a result, the contaminants can have adverse effects, such ...
