  • Patent number: 12022889
    Abstract: A smoking system including a mouthpiece with a flavor releasing mechanism in its inner volume is provided. The mouthpiece includes a rigid material (e.g., glass or ceramic) that may be coupled to a smokable rod or cone. A force-applying member is located within the inner volume adjacent the flavor ball and is coupled to an elongate movable member extending out an end of the mouthpiece. Movement of the elongate movable member causes the force-applying member to apply a force to the flavor ball causing the ball to burst. Once the flavor ball bursts, the ball releases its flavoring substance into smoke passing through the mouthpiece to enhance the smoking experience.

  • Patent number: 9554594
    Abstract: A filter element incorporating an adsorbent material is provided. The filter element may comprise a first section of filter material and a second section of filter material spaced apart to form a compartment therebetween. The compartment may be filled with one or more adsorbents or the compartment may be divided into two regions, wherein one compartment region is filled with an adsorbent and the other compartment region is either filled with an ion-exchange resin or remains empty. The section of filter material adjacent to the tobacco rod may include one or more channels therethrough for passaging smoke directly from the tobacco rod into the adsorbent-filled compartment. The mouth end section of filter material may contain a breakable capsule, wherein the breakable capsule is filled with a flavoring agent capable of altering the taste characteristics of mainstream smoke.

  • Patent number: 9051797
    Abstract: A well chemical dispensing system includes a tubular sub for securing into a drill string. A ball stop is located within the passage. A ball filled with a liquid surfactant is pumped down the well. The ball is formed of a frangible material for shattering on impact with the ball stop, so as to dispense the surfactant, causing foaming when mixing with well fluid. Struts within the ball extend across an interior of the ball and join to inner surfaces of the ball. The struts are formed of a solid surfactant material. The ball has a spherical shape with dimples formed in an exterior surface of the sphere. A spring in the passage applies an upward force on the ball stop. The ball stop has upper and lower grids extending across the passage.

  • Publication number: 20150027477
    Abstract: [Problems] The present invention provides a filter containing built-in capsule in which a tobacco flavor enhancing liquid that can enhance flavor aspects such as taste, aroma, and richness is encapsulated, along with a cigarette and cigarette substitute comprising this filter. [Resolution means] The cigarette in which filter containing built-in capsule 1 according to the present invention is incorporated includes cut leaf 2, rolling paper 3, filter 4, and tip paper 5, with easily breakable capsule 6 incorporated in filter 4, and tobacco flavor enhancing liquid 8 including natural cacao extract encapsulated in film 7. When smoking, by pinching the filter part to crush capsule 6, film 7 bursts, causing tobacco flavor enhancing liquid 8 to ooze into filter 4 and enabling enhancement of the taste, aroma, richness, etc. specific to tobacco.
