Drinking straw with integral filtration system

[0002] 1. Field of the Invention

[0003] The present invention relates generally to water filtration and, more specifically, to a drinking straw with an integral filtration system including a plurality of filter types to extract or neutralize toxins such as heavy metals, chemicals, microbiological cysts and other such impurities and contaminants from a fluid as it is being consumed.

[0004] 2. Description of Art

[0005] Numerous vehicle-drinking fluid purification devices are known in the art. While these devices may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present described.

[0006] A primary object of the present invention is to provide a drinking straw having a fluid filtration system integral with the straw wherein any fluid drawn therethrough by a user must pass through said filtration system to remove any undesirable contaminants or pathogens that might present a health hazard to the user prior to introduction into the users body.

[0007] Another object of the present invention is to provide a drinking straw having an integral filtration system comprising a plurality of filter elements each designed to remove specific contaminants.

[0008] Still another object of the present invention is to provide a drinking straw having an integral filtration system that allows the user to purify a beverage by simply drinking the fluid through the straw of the present invention.

[0009] Yet another object of the present invention is to provide a drinking straw having an integral filtration system including a charcoal filter, a wool filter and a bacterial filter in series.

[0010] Another object of the present invention is to provide a drinking straw having an integral filtration system that allows the user to purify beverages inconspicuously without bringing it to the attention of others.

[0011] One other object of the present invention is to provide a drinking straw having an integral filtration system that is compact enough to be carried in a users pocket.

[0012] Another object of the present invention is to provide a drinking straw having an integral filtration system that is simple and easy to use.

[0013] Yet another object of the present invention is to provide a drinking straw having an integral filtration system that is inexpensive to manufacture to and operate.

[0014] Additional objects of the present invention will appear as the description proceeds.

[0015] The present invention overcomes the shortcomings of the prior art by providing a drinking straw with an integral filter system to remove a wide range of pathogens that may compromise the health of the user if taken internally with the user only needing to drink the fluid through the straw to perform the purification process. The present invention may be used easily and inconspicuously in public.

[0016] The foregoing and other objects and advantages will appear from the description to follow. In the description reference is made to the accompanying drawing, a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. These embodiments will be described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that structural changes may be made without departing from the scope of the invention. In the accompanying drawing, like reference characters designate the same or similar parts throughout the several views.

[0017] In order that the invention may be more fully understood, it will now be described, by way of example, with reference to the accompanying drawing in which:

[0042] The following discussion describes in detail one embodiment of the invention and several variations of that embodiment. This discussion should not be construed, however, as limiting the invention to those particular embodiments. Practitioners skilled in the art will recognize numerous other embodiments as well. For a definition of the complete scope of the invention, the reader is directed to the appended claims.

[0043] Referring to FIG. 1, shown is the present invention in use. The purification system 10 of the present invention comprises a tubular member 12 having a throughbore 14 with said tubular member 12 having a first end 16 and second end 18. The first end 16 is inserted into the mouth while the second distal end 18 is inserted into a beverage 20 to be consumed. The tubular member 12 contains at least one filtering element, not shown, that is used to remove impurities from the beverage. The straw can be used anywhere suspicion of unfiltered drinking water exists, such as a park water fountain, restaurants, vacation trips or general travel.

[0044] Referring to FIG. 2, shown is a section view of the purification system 10, of the present invention. The tubular member 12 having a throughbore 14 with said tubular member 12 having a first end 16 and second end 18. The first end 16 is inserted into the mouth while the second distal end 18 is inserted into a beverage to be consumed. The tubular member 12 contains in the preferred embodiment a granulated carbon filter element 22, fibrous filter element 24 and biological filter element 26 that are used in combination to remove impurities from a predetermined beverage.

[0045] Referring to FIG. 3, shown is the filtering elements of the purification system 10 of the present invention. The tubular member 12 has a throughbore 14 wherein is fixedly positioned a plurality of filtering elements. One is a charcoal filtering element 22, fibrous filtering element, in the preferred embodiment wool 24 and a biological filtering element 26. Each of the filtering elements performs a function that will result in the removal from a predetermined beverage certain impurities that can be harmful to human life.

[0049] Referring to FIG. 7, shown is a chart 34 of the impurities and undesirable properties that the combination of the charcoal filtering element 22, fibrous filtering element 24 and biological filtering element 26 working in conjunction with each other will help to reduce if not eliminate. The purification system 10 is designed to reduce the intake of microbiological cysts, harmful contaminants and other impurities from a beverage.

[0050] Referring to FIG. 8, shown is a section view of the purification system 10 of the present invention having a fluid passing therethrough. The purification system 10 of the present invention comprises a tubular member 12 having a throughbore 14 with said tubular member 12 having a first end 16 and second end 18. The first end 16 is inserted into the mouth while the second distal end 18 is inserted into a beverage 20 to be consumed.
