This invention relates generally to the field of cigarette filters and more specifically to helical shaped filter made of biodegradable material Cigarette type devices have been in use for many years as a means to smoke botanical materials such as tobacco or cannabis.
Cannabis has been made legal in many states recently. Therefore, the opportunity to sell a cannabis-based cigarette is now legally feasible. Cigarette filters are traditionally made of cellulose acetate, which is a plastic and not biodegradable. Therefore, the filters take many years to decompose and present an environmental problem. Additionally, traditional cigarette filters require a relatively hard draw, which may not be conducive to the smoking of cannabis type material These two issues create a deficiency in the prior technology
The primary object of the invention is to provide a helical shaped filter for a cigarette shaped smoking device that is biodegradable.
Another object of the invention is to provide a biodegradable helical shaped filter that impedes the release of shredded botanical material yet allows the flow of smoke and air.
Another object of the invention is to provide a biodegradable helical shaped filter that causes the inhaled smoke and air to take longer to reach the mouth of the user thereby allowing time for the smoke and air to become cooler.
Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.
In accordance with a preferred embodiment of the invention, there is disclosed a helical shaped filter made of biodegradable material comprising: a helical shaped member made of biodegradable material, said helical shape having an S shaped cross section, said biodegradable capable of withstanding temperatures as high as one hundred and eighty degrees Fahrenheit, said helical shaped member being fitted into the end portion of a cigarette containing shredded botanical material, said helical shaped member having a wall thickness of approximately fifty thousandths of an inch, said helical shaped member having an overall length of approximately three quarters of an inch to one and one quarter of an inch, and said helical shaped member having an overall diameter of approximately three hundred thousandths of an inch.
The drawings constitute a part of this specification and include exemplary embodiments to the invention, which may be embodied in various forms. It is to be understood that in some instances various aspects of the invention may be shown exaggerated or enlarged to facilitate an understanding of the invention.
Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.
Referring now to
The resulting filter 2 is totally biodegradable and is also FDA approved to be in close proximity to a user's mouth.
The filter 2 or 3 may be amended with additional materials for both flavoring and for added particulate capture. These include but are not limited to activated coco carbon, beet flour, rice flour, corn flour, quina flour, lentil, or bean flower.
Additionally, the biodegradable material used in conjunction with the present invention including a finely chopped paper version, cardboard version or an extruded clay version. These materials would be worked with in a similar way where they are formed in a moist format and then heated to dive out liquid to form a rigid filter product.
While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
