Filter for cannabis or tobacco consumption

Abstract

Filters of conventional design consist of a small paper tube which is filled with activated carbon and is closed at both ends by cellulose fibres and / or ceramic caps. Filters consisting only of cellulose also exist. The filters are used to rotate them with cigarette paper to form a cigarette or a joint. In normal use, one of the filter ends can be singed or burned when the cigarette or the joint is smoked to the end. In addition, specifically in the case of cannabis, oils emerging as a result of heat can clog the cellulose, but in particular also the small air passages of ceramic caps. The invention is intended, by means of the thermal insulation, to prevent scorching and clogging of the filter elements. The filter elements consist of cellulose and carbon or consist of ceramic cap / carbon or only cellulose and are to be placed centrally in a small tube consisting of paper. The cavities between the filter elements and the end of the tube are to be filled with specially shaped inserts made of paper or ceramic. The extension of the filter on both sides by the small paper tube is intended to ensure thermal insulation and to prevent the embers from being in direct contact with the cellulose filter or with the ceramic cap. As a result of the enlarged area, the specially shaped inserts made of paper or ceramic are intended to prevent clogging by emerging oils. In addition, the inserts prevent tobacco or cannabis particles from being able to fall unhindered into the paper tube.

Description

FILTER FOR CANNABIS OR TOBACCO CONSUMPTION Technical field:

[0001] Smoking accessories, cigarette filters State of the art:

[0002] It is known that filters for tobacco or cannabis are usually constructed from several layers or materials. The outer layer is typically made of paper or other porous materials that serve to channel and direct the smoke. Inside the filter, further materials such as activated carbon or cellulose are often arranged to remove harmful chemicals and particles from the smoke.

[0003] Activated carbon filters are typically embedded as a layer within the filter. This activated carbon layer consists of fine-grained carbon with a porous structure, providing a large surface area, which is usually encapsulated with ceramic caps. This structure allows the activated carbon to adsorb a wide variety of pollutants in the smoke, including heavy metals, volatile organic compounds, and other harmful substances. Cellulose filters are often used in conjunction with activated carbon or as a separate layer within the filter. These filters consist of fine fibers that allow for effective smoke filtration. The cellulose fibers trap particles and pollutants in the smoke before the purified smoke passes through the filter. By combining activated carbon and cellulose, filters can provide comprehensive smoke purification, thus improving the smoking experience. Inventions:

[0004] The invention specified in claim 1 addresses the problems that, with proper handling of conventional filters, there is a risk of the cellulose fibers burning, and, especially in the case of cannabis consumption, it prevents oils dissolved by heat from running into the cellulose filter or the ceramic cap and clogging it.

[0005] These problems are solved by the features listed in claim 1.

[0006] Claim 1 comprises a filter element for the consumption of cannabis or tobacco, which provides thermal insulation for the cellulose filter in the center. This filter element consists of a double-sided extended filter sleeve with specially shaped paper or ceramic inserts forming a grid. These inserts serve to surround the cellulose filter in the center and protect it from excessive heat transfer. The filter sleeve and the inserts are designed to maintain a defined safety distance from the center of the cellulose filter or the ceramic cap, respectively. This design allows the smoke to flow through the filter while preventing unwanted heat transfer to the filter material. This avoids the risk of burning or damaging the cellulose fibers. Simultaneously, when consuming cannabis, the heat-released oils cannot directly clog the cellulose or ceramic caps, as the filter housing and mesh significantly increase the surface area. The cellulose filter or cellulose-carbon filter unit is centrally located to allow for use from either side.
