The public today has available to it a large selection of drinks to chose from in order to ingest at home, on the run, or in a restaurant or bar. Many of the available drinks are very thick, making them hard to drink using a drinking straw currently found on the market, or they may contain ice, seeds, pulp, unwanted physical contaminants or other non-dissolved items that should not, or may not, want to be ingested by the user.
The present invention relates to an inexpensive drinking straw that solves the problems of filtering drinks through the use of a filter element. The present invention can also be used to increase the open area that is available to the liquid in a drinking straw in order to reduce the effort needed by a user to ingest the liquid.
Numerous drinking fluid purification devices are known in the art for the filtering of biological or toxic dissolved materials in an attempt to make the fluid purified for drinking but these are not relevant to the present invention. U.S. Pat. Nos. 6,811,036 B1, 5,518,613 and 4,995,96.
Based upon the foregoing, there is a need for a device that can accomplish the filtering of drinks, in a simple and economic manner, in order to prevent the ingestion of any non-dissolved contaminants or other undesired physical elements contained in a drink without the use of complicated filtering materials that may be used for the removal of biological or toxic contaminants.
The object of the present invention is to provide an inexpensive device for the filtering of non-dissolved contaminates in a liquid from being ingested by the user of the straw. The present invention is unique in its field.
The following discussion describes in detail one embodiment of the invention and several other possible embodiments. As shown in
In another embodiment of the invention, both ends of the drinking straw are open, as shown in
In the above mentioned embodiments the number and size of the openings can be adjusted for the size of the objects to be filtered and for the viscosity of the drink to allow for easier drinking as shown in
Although the preferred embodiments of the invention have been disclosed for illustrative purposes, those skilled in the art will appreciate the various modifications, additions, and substitutions are possible, without departing from the scope and sprit of the invention as disclosed in the accompanying claims
